Context Low bone mineral density has been reported in individuals with congenital adrenal hyperplasia (CAH), but the prevalence of fractures is unclear. Objective To study the prevalence of fractures in CAH. Design, Setting, and Participants Patients with CAH (n = 714, all 21-hydroxylase deficiency) were compared with controls matched for sex and year and place of birth (n = 71 400). Data were derived by linking National Population-Based Registers. Main Outcome Measures Number and type of fractures. Results Mean age was 29.8 ± 18.4 years. Individuals with CAH had more fractures compared to controls [23.5% vs 16.1%, odds ratio (OR) 1.61, 95% CI 1.35-1.91], and this was found in both sexes (females: 19.6% vs 13.3%, OR 1.57, 95% CI 1.23-2.02; males: 28.7% vs 19.6%, OR 1.65, 95% CI 1.29-2.12). Fractures were significantly increased in patients born before the introduction of neonatal screening but not in those born afterwards. Any major fracture associated with osteoporosis (spine, forearm, hip, or shoulder) was increased in all individuals with CAH (9.8% vs 7.5%, OR 1.34, 95% CI 1.05-1.72). The highest prevalence of fractures was seen in SV phenotype and I172N genotype while nonclassic phenotype and I2 splice genotype did not show increased prevalence. A transport accident as a car occupant and fall on the same level were more common in patients with CAH, both sexes, than in controls. Conclusions Patients with CAH had an increased prevalence of both any fracture and fractures associated with osteoporosis (both sexes) but not for patients neonatally screened. We conclude that fracture risk assessment and glucocorticoid optimization should be performed regularly.

Background Turner syndrome is the result of the partial or complete absence of an X chromosome in phenotypic girls. This can cause an array of medical and developmental difficulties. The intelligence quotient in females with Turner syndrome has previously been described as uneven, but considered within normal range. Although their social, intellectual, and psychiatric profile is described, it is unclear to what extent these females meet the clinical criteria for neurodevelopmental or psychiatric diagnoses. The aim of this study was to examine the prevalence of neurodevelopmental and psychiatric disorders in females with Turner syndrome. Methods A retrospective cohort study was performed with a total of 1392 females with Turner syndrome identified through the Swedish National Patient Register and compared with 1:100 age- and sex-matched controls from the general population. The associations between Turner syndrome and diagnoses of neurodevelopmental and/or psychiatric disorders were calculated using conditional logistic regression and is presented as estimated risk (odds ratio, OR, 95% confidence interval, CI) in females with Turner syndrome compared with matched controls. Results Females with Turner syndrome had a higher risk of neurodevelopmental or psychiatric disorder (OR 1.37, 95% CI 1.20–1.57), an eightfold increased risk of intellectual disability (OR 8.59, 95% CI 6.58–11.20), and a fourfold increased risk of autism spectrum disorder (OR 4.26, 95% CI 2.94‑6.18) compared with the controls. In addition, females with Turner syndrome had twice the risk of a diagnosis of schizophrenia and related disorders (OR 1.98, 95% CI 1.36–2.88), eating disorders (OR 2.03, 95% CI 1.42–2.91), and behavioral and emotional disorders with onset in childhood (OR 2.01, 95% CI 1.35–2.99). Conclusions Females with Turner syndrome have an increased risk of receiving a diagnosis of neurodevelopmental or psychiatric disorder. This warrants extensive assessment of intellectual and cognitive functions from early age, and increased psychiatric vigilance should be a part of lifelong healthcare for females with Turner syndrome.

Background The impact of adrenalectomy on morbidity in patients with mild hypercortisolism and non-functioning adrenocortical adenoma is unclear. The present study evaluated morbidity before and after adrenalectomy in patients with benign adrenocortical tumour with Cushing´s syndrome (CS), autonomous cortisol secretion (ACS) and non-functioning adrenocortical adenoma as assessed by national and quality registries. Methods Patients registered in the Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal Surgery (SQRTPA) 2009–2017 with CS, ACS or non-functioning adrenocortical adenoma, were included in this retrospective study and analysed with age- and sex-matched controls, 1:3. Morbidity associated with CS was assessed pre- and postoperatively by analysing data from the Swedish National Patient Register and the Swedish Prescribed Drug Register. Results Some 271 patients were included, CS (127), ACS (45) and non-functioning adrenocortical adenoma (99), with 813 matched controls. The frequency of hypertension was almost 50% in all tumour groups. Antihypertensive medication preoperatively was more frequent in all tumour groups compared with controls. No preoperative differences in medication were detected between patients with CS and ACS. A decrease in the use of hypertensive drugs was noticed annually for all patient groups after adrenalectomy. Conclusions Hypertension is common in patients with benign adrenocortical tumours regardless of cortisol hypersecretion. The use of antihypertensive drugs in patients with CS, ACS and non-functioning adrenocortical adenoma was reduced after adrenalectomy. These findings highlight the need for a randomized controlled trial to investigate the impact of adrenalectomy on morbidity in patients with mild hypercortisolism.

Objectives To determine trends in clinical practice for individuals with DSD requiring gonadectomy. Design Retrospective cohort study. Methods Information regarding age at gonadectomy according to diagnosis; reported sex; time of presentation to specialist centre; and location of centre from cases reported to the International DSD Registry and who were over 16 years old in January 2019. Results Data regarding gonadectomy were available in 668 (88%) individuals from 44 centres. Of these, 248 (37%) (median age (range) 24 (17, 75) years) were male and 420 (63%) (median age (range) 26 (16, 86) years) were female. Gonadectomy was reported from 36 centres in 351/668 cases (53%). Females were more likely to undergo gonadectomy (n = 311, P < 0.0001). The indication for gonadectomy was reported in 268 (76%). The most common indication was mitigation of tumour risk in 172 (64%). Variations in the practice of gonadectomy were observed; of the 351 cases from 36 centres, 17 (5%) at 9 centres had undergone gonadectomy before their first presentation to the specialist centre. Median age at gonadectomy of cases from high-income countries and low-/middle-income countries (LMIC) was 13.0 years (0.1, 68) years and 16.5 years (1, 28), respectively (P < 0.0001) with the likelihood of long-term retention of gonads being higher in LMIC countries. Conclusions The likelihood of gonadectomy depends on the underlying diagnosis, sex of rearing and the geographical setting. Clinical benchmarks, which can be studied across all forms of DSD will allow a better understanding of the variation in the practice of gonadectomy.

Purpose of review The introduction of synthetic glucocorticoids 70 years ago made survival possible in classic 21-hydroxylase deficiency (21OHD). The currently used glucocorticoid therapy may lead to unphysiological dosing with negative consequencies on health in addition to the problems that may arise due to androgen over-exposure. Recent findings Fertility in females with 21OHD seemed to be impaired, especially in the salt-wasting (SW) phenotype but when pregnancies did occur there was a higher risk for gestational diabetes and cesearean section. Increased fat mass, body mass index, insulin resistance and frequency of autoimmune disorders as well as impaired echocardiographic parameters and lower bone mineral density were found in 21OHD compared to controls. Negative effects on cognitive functions have been identified. Adrenal tumors, especially myelolipomas, were prevalent. Increased knowledge on steroid metabolism in 21OHD and urine steroid profiling may improve assessment of treatment efficacy. Nevanimibe, abiraterone acetate and anastrozole may have a place in the future management of 21OHD. Long-acting glucocorticoids may be a less favorable, especially dexamethasone. Summary The various clinical outcomes need regular monitoring. Negative consequencies are to large extent the result of the unphysiological glucocorticoid replacement. Modern management with improved follow-up and future addition of new drugs may improve outcomes.

Background Although congenital adrenal hyperplasia (CAH) is known to be associated with adrenal crises (AC), its association with patient- or clinician-reported sick day episodes (SDE) is less clear. Methods Data on children with classic 21-hydroxylase deficiency CAH from 34 centers in 18 countries, of which 7 were Low or Middle Income Countries (LMIC) and 11 were High Income (HIC), were collected from the International CAH Registry and analyzed to examine the clinical factors associated with SDE and AC. Results A total of 518 children—with a median of 11 children (range 1, 53) per center—had 5388 visits evaluated over a total of 2300 patient-years. The median number of AC and SDE per patient-year per center was 0 (0, 3) and 0.4 (0.0, 13.3), respectively. Of the 1544 SDE, an AC was reported in 62 (4%), with no fatalities. Infectious illness was the most frequent precipitating event, reported in 1105 (72%) and 29 (47%) of SDE and AC, respectively. On comparing cases from LMIC and HIC, the median SDE per patient-year was 0.75 (0, 13.3) vs 0.11 (0, 12.0) (P Conclusions The real-world data that are collected within the I-CAH Registry show wide variability in the reported occurrence of adrenal insufficiency–related adverse events. As these data become increasingly used as a clinical benchmark in CAH care, there is a need for further research to improve and standardize the definition of SDE.

Disorders of sex development (DSDs) may affect the gonadal function and thereby the puberty. The pubertal development may be absent, incomplete, or the hormonal effects may be different than anticipated. Because of a high risk of malignancy, gonadectomy is often performed. Hormone secretion from a gonadal tumor may even be the presenting symptom complicating the diagnosis. A need for treatment with testosterone or estrogen is not uncommon, also in cases with a spontaneous start of puberty. This review will focus on the clinical presentations during puberty in different types of DSDs, with the aim to facilitate identification of individuals with an atypical pubertal development indicative of a DSD and to ensure proper referrals and initiation of adequate investigations and treatments.

Purpose Surgery is recommended for most patients with gastro-entero-pancreatic neuroendocrine neoplasias (GEP-NENs). Rates of complications and perioperative mortality have been reported in few mostly retrospective single-center series, but there has been no detailed analysis on risk factors for perioperative complications and mortality to date. Methods Data of patients with GEP-NENs operated between January 2015 and September 2018 were retrieved from EUROCRINE©, a European online endocrine surgical quality registry, and analyzed regarding rate and risk factors of surgical complications. Risk factors were assessed by logistic regression. Results Some 376 patients (211 female, 167 male; age median 63, range 15–89 years) were included. Most NENs were located in the small intestine (SI) (n = 132) or pancreas (n = 111), the rest in the stomach (n = 34), duodenum (n = 30), appendix (n = 30), colon, and rectum (n = 22), or with unknown primary (n = 15). Of the tumors, 320 (85.1%) were well or moderately differentiated, and 147 (39.1%) of the patients had distant metastases at the time of operation. Severe complications (Dindo-Clavien ≥ 3) occurred in 56 (14.9%) patients, and 4 (1.1%) patients died perioperatively. Severe complications were more frequent in surgery for duodenopancreatic NENs (n = 31; 22.0%) compared with SI-NENs (n = 15; 11.4%) (p = 0.014), in patients with lymph node metastases operated with curative aim of surgery (n = 24; 21.4%) versus non-metastasized tumors or palliative surgery (n = 32; 12.1%) (p = 0.020), and in functioning tumors (n = 20; 23.0%) versus non-functioning tumors (n = 30; 13.5%) (p = 0.042). Complication rates were not significantly associated with tumor stage or grade. Conclusions Severe complications are frequent in GEP-NEN surgery. Besides duodenopancreatic tumor location, curative resection of nodal metastases and functioning tumors are risk factors for complications.

Purpose Patients with classic congenital adrenal hyperplasia (CAH) are treated postnatally with life-long glucocorticoid (GC) replacement therapy. Although prolonged exposure to GCs may have a negative impact on behaviour, few studies have studied this issue. We therefore investigated behavioural outcomes in male and female children and adolescents with CAH. Methods An observational study in which Swedish and Italian children and adolescents with CAH identified through neonatal screening for CAH (n = 57, age range 7–17 years) were compared with healthy population controls matched for age and sex (n = 72, age range 7–17 years). Thirteen (eight females) of the fifty-seven children and adolescents with CAH had been treated prenatally with dexamethasone (DEX). Standardised questionnaires for parents and self-report scales for children/adolescents were used to assess behavioural and emotional problems, social anxiety, temperament and scholastic competence. Results There were no statistically significant differences between CAH patients (not prenatally treated with DEX) and controls on most of the scales measuring adaptive functioning or behavioural problems. However, children with CAH were rated by their parents to have more social problems than controls (Child Behaviour Checklist, CBCL social problems, p = 0.032). In the small group (n = 13) of prenatally DEX-treated cases parents rated their children/adolescents to have more mood problems compared with non-DEX-treated children/adolescents with CAH (CBCL-withdrawn/depressed, p = 0.019). Conclusion Children/adolescents with CAH showed good overall adjustment. The clinical significance of the parentally perceived increase in social problems in children/adolescents with CAH requires further investigation. The findings underline the importance of psychological support for children/adolescents with a chronic condition.

Inborn errors of mitochondrial fatty acid oxidation (FAO), such as medium-chain acyl-CoA dehydrogenase deficiency (MCAD) and very long-chain acyl-CoA dehydrogenase deficiency (VLCAD) affects cellular function and whole-body metabolism. Carnitine uptake deficiency (CUD) disturbs the transportation of fatty acids into the mitochondria, but when treated is a mild disease without significant effects on FAO. For improved clinical care of VLCAD in particular, estimation of FAO severity could be important. We have investigated whether the oxygen consumption rate (OCR) of peripheral blood mononuclear cells (PBMCs) obtained from patients with MCAD, VLCAD, and CUD can be used to study cellular metabolism in patients with FAO defects and to determine the severity of FAO impairment. PBMCs were isolated from patients with VLCAD (n = 9), MCAD (n = 5–7), and CUD (n = 5). OCR was measured within 6-hours of venous puncture using the Seahorse XFe96. The PBMCs were exposed to glucose alone or with caprylic acid (C8:0) or palmitic acid (C16:0). OCR was significantly lower in cells from patients with β-oxidation deficiencies (MCAD and VLCAD) compared to CUD at basal conditions. When exposed to C16:0, OCR in VLCAD cells was unchanged, whereas OCR in MCAD cells increased but not to the levels observed in CUD. However, C8:0 did not increase OCR, as would be expected, in VLCAD cells. There was no clear relationship between clinical severity level and OCR. In patients with β-oxidation deficiencies, changes of mitochondrial respiration in PBMCs are detectable, which indicate that PBMCs have translational potential for studies of β-oxidation defects. However, further studies are warranted. Title in Web of Science: Altered mitochondrial metabolism in peripheral blood cells from patients with inborn errors of beta-oxidation

Contains fulltext : 244176.pdf (Publisher’s version ) (Closed access) Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders affecting cortisol biosynthesis. Reduced activity of an enzyme required for cortisol production leads to chronic overstimulation of the adrenal cortex and accumulation of precursors proximal to the blocked enzymatic step. The most common form of CAH is caused by steroid 21- hydroxylase deficiency due to mutations in CYP21A2. Since the last publication summarizing CAH in Endocrine Reviews in 2000 there have been numerous new developments. These include more detailed understanding of steroidogenic pathways, refinements in neonatal screening, improved diagnostic measurements utilizing chromatography and mass spectrometry coupled with steroid profiling, and improved genotyping methods. Clinical trials of alternative medications and modes of delivery have been recently completed or are under way. Genetic and cell-based treatments are being explored. A large body of data concerning long-term outcomes in patients affected by CAH, including psychosexual well-being, has been enhanced by the establishment of disease registries. This review provides the reader with current insights in congenital adrenal hyperplasia with special attention to these new developments.

Background Prenatal treatment with dexamethasone (DEX) reduces virilization in girls with congenital adrenal hyperplasia (CAH). The treatment is effective but may result in long-lasting adverse effects. In this study we explore the effects of DEX on metabolism in individuals not having CAH but treated with DEX during the first trimester of fetal life. Method All DEX-treated participants (n = 40, age range 5.1-26.4 years) and controls (n = 75, age range 4.5-26.6 years) were assessed with fasting blood samples to measure blood count, renal function, glucose homeostasis, and serum lipid profiles. Results There were no significant differences between DEX and control participants for birth parameters, weight and height, or body mass index at the time of testing. Analyzing the entire cohort, we found no significant effects of DEX on blood count, renal function, or serum lipid profiles. However, a lower HOMA-β index in the DEX-treated individuals (U = 893.0; P = 0.049) was observed. Post hoc analyses revealed an effect in girls (U = 152.5; P = 0.024) but not in boys (U = 299.5; P = 0.550). The effect on HOMA-β persisted (U = 117.5; P = 0.048) after analyzing data separately in the participants < 16 years of age. In addition, we observed higher plasma glucose levels (F = 14.6; P = 0.001) in the DEX-treated group. The participants ≥ 16 years of age in the DEX-treated group had significantly higher total plasma cholesterol (F = 9.8; P = 0.003) and higher low-density lipoprotein cholesterol levels (F = 7.4; P = 0,009). Conclusion Prenatal DEX exposure in early pregnancy has negative effects on beta-cell function and lipid profile in individuals without CAH already at a young age.

Context Prenatal treatment of human disease is rare. Dexamethasone (DEX) is used in pregnancies at risk for congenital adrenal hyperplasia (CAH) to prevent virilization in an affected female fetus. The safety and long-term consequences of prenatal DEX exposure on the brain are largely unknown. Objective We investigate whether first-trimester prenatal DEX treatment is associated with alterations in brain structure at adult age, and if these alterations are associated with DNA methylation, mood, and cognitive abilities. Design, Setting, and Participants T1-weighted and diffusion-weighted imaging scans, from a single research institute, are compared between 19 (9 women) first-trimester DEX-treated individuals, at risk of CAH but not having CAH, and 43 (26 women) controls (age range, 16.0-26.4 years). Results DEX-treated participants showed bilateral enlargement of the amygdala, increased surface area and volume of the left superior frontal gyrus, and widespread increased radial, mean, and axial diffusivity of white matter, in particular in the superior longitudinal fasciculi and corticospinal tracts. In the DEX-treated group, increased mean and radial diffusivity correlated with increased methylation of the promotor region of the FKBP5 gene. There were no group differences in cognition or in scales assessing depression or anxiety, and the relationship between brain structure and cognition did not differ between DEX-treated and controls. Conclusions First-trimester prenatal DEX treatment is associated with structural alterations of the brain at adult age, with an accompanying change in gene methylation. The findings add to the safety concerns of prenatal DEX treatment in the context of CAH.

Context Little is known about the physical health of individuals with 46,XY disorders of sex development (DSD). Objective To assess physical and reported subjective health of individuals with XY DSD. Methods As part of the dsd-LIFE study, patients with an XY DSD condition were analyzed in different diagnosis groups for metabolic parameters, comorbidities, metabolic syndrome, bone outcomes, and reported subjective health. Findings were evaluated by descriptive statistics. Results A total of 222 patients with XY DSD were included with a mean age of 28.8 ± 12.2 years, mean height of 175.3 ± 7.7 cm, mean weight of 74.3 ± 20.0 kg, and mean body mass index of 24.1 ± 6.0 kg/m2. Obesity rate was not increased when descriptively compared with Eurostat data. Fourteen patients had metabolic syndrome (14/175; 8.0%). In descriptive comparison with data from the DECODE study and World Health Organization, subjects fared better in the categories waist circumference, glucose, triglyceride, cholesterol, and high-density lipoprotein. Of participants with available bone health data, 19/122 (15.6%) patients had a Z-score ≤ –2.0 at lumbar spine indicating lowered bone mineral density (BMD). Mostly gonadectomized individuals with complete androgen insensitivity syndrome (CAIS) and no estrogen therapy had lowered BMD at lumbar spine. Individuals with XY DSD performed poorly in the category subjective health in descriptive comparison with Eurostat data. Conclusion Participants reported a lower subjective health status than Eurostat data but their overall metabolic health status was good. Decreased BMD at lumbar spine was especially present in gonadectomized individuals with CAIS and no estrogen therapy.

Summary Background Surgery is performed in many individuals with disorders/differences of sex development (DSD). Irreversibility of some surgical procedures, lack of information about the procedures, and lack of follow-up care for physical and psychological outcomes, lead to wish for more knowledge from both surgeons and patients. After the consensus conference in 2006, multidisciplinary care is provided to a higher degree with psychological support and more restricted surgical procedures. Outcome studies after genital surgery often lack of patient's perspective. Objective To describe surgical procedures in relation to diagnosis, to evaluate the outcomes of surgery through genital examination, and through patient's and observer's satisfaction with the anatomical and functional result after genital surgery. Study design In a cross-sectional clinical study performed in six European countries in 2014/15, we have included 500 participants where surgery was performed, from a total of 1040 adolescents (≥16years) and adults with a DSD. Diagnoses included Turner syndrome (n = 301), mixed gonadal dysgenesis (45,XO/46,XY; n = 45), Klinefelter syndrome (n = 218), XYY (n = 1), 46, XY DSD (n = 222) and 46, XX DSD (n = 253). Study protocol included clinical report files, an optional gynecological or urological examination, patient reported outcomes including received surgical interventions, satisfaction with appearance and function after surgery, and impact of the surgical procedure on life. Results Five hundred participants had received genital or breast surgery, with the highest rate in 46, XY DSD and the lowest in Turner syndrome. Altogether; 240 participants had feminizing surgery, 112 had masculinizing surgery, and 217 underwent gonadectomy. Physicians evaluated anatomical appearance at genital examination as poor in less than 10%. Dissatisfaction with anatomical appearance was reported by 22% of the participants, dissatisfaction with function by 20%. Being (very) dissatisfied with anatomical appearance and function was reported by 13% of the study participants. Most participants reported no impact, or positive impact, of the surgical procedures on their lives, but 29% experienced a negative effect of gonadectomy on their life. Discussion There might be a selection bias and/or a recall bias for participating in our studies. Due to poor data quality about surgical procedures performed in the past, we also relied on participants memory about surgical procedures in their past. Ideally, patient reported outcomes should be evaluated both before and after surgical procedures. Conclusion A vast majority are satisfied with appearance and function, but still genital or breast surgery have a long-lasting effect on patient's life. Self-reported satisfaction is usually lower than the observer's evaluation regarding both appearance and function.

Background Fertility in men with hypospadias may be affected due to anatomical, surgical, or etiological factors and associated conditions. Fertility is further influenced by psychosocial and genetic factors, often shared within families. Objective To evaluate fertility in men born with hypospadias and assess confounding by familial factors. Materials and methods A population-based cohort of 1.2 million men born in Sweden 1964-1998, identified through national demographic and healthcare registers. Associations between hypospadias and (a) being a biological father, (b) conceiving through ART, and (c) diagnosis of male infertility were investigated in the full cohort with logistic regression models and Cox proportional hazard models, expressed as odds ratios (ORs) and hazard ratios (HRs), respectively, with 95% confidence intervals (CIs). A stratified proportional hazard model, conditional on sibling group, was used to control for shared familial confounding. Results Men with hypospadias, as a whole group, had a lower probability of having biological children (adjusted HR 0.87, 95% CI 0.83-0.92). A significant association was present in both distal (adjusted HR 0.90, 95% CI 0.85-0.96) and proximal hypospadias (HR 0.59, 95% CI 0.42-0.81). Men with hypospadias more often became fathers through ART, regardless of concomitant cryptorchidism. The initial association between hypospadias and the diagnosis of infertility disappeared in sensitivity analyses excluding cryptorchidism. Discussion Men with hypospadias displayed lower birthrates as compared to their brothers and the general population. Mere birthrates may, however, be a questionable measure of fertility in a population using family planning. However, men with hypospadias were also at higher risk of reproducing through ART and did more often receive a diagnosis of male infertility. Altogether, these findings indicate impaired fertility in men with hypospadias. Conclusions Fertility in men with hypospadias is impaired, as shown by lower birthrates, increased use of ART and higher risk of receiving a diagnosis of male infertility.

Background Primary aldosteronism (PA) is the most common cause of secondary hypertension. Surgery is the mainstay of treatment for unilateral dominant PA, but reported cure rates varies. The aim of the present study was to investigate contemporary follow-up practices and cure rates after surgery for PA in Sweden. Methods Patients operated for PA and registered in the Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal Surgery (SQRTPA) 2009–2015 were identified. Patient data were extracted, and follow-up data (1–24 months) was recorded. Doses of antihypertensive medication and potassium supplementation were calculated using defined daily doses (DDD), and the Primary Aldosteronism Surgical Outcome (PASO) criteria were used to evaluate outcomes. Results Of 190 registered patients, 171 (47% female, mean age 53 years, median follow-up 3.7 months) were available for analysis. In 75 patients (44%), missing data precluded evaluation of biochemical cure according to the PASO criteria. Minimal invasive approach was used in 168/171 patients (98%). Complication rate (Clavien-Dindo >3a) was 3%. No mortality was registered. Pre/postoperatively 98/66% used antihypertensives (mean DDD 3.7/1.5). 89/2% had potassium supplementation (mean DDD 2.0/0) before/after surgery. Complete/partial biochemical and clinical success according to the PASO criteria were achieved in 92/7% and 34/60%, respectively. Conclusion In this study, reflecting contemporary clinical practice in Sweden complete/partial biochemical and clinical success after surgery for PA was 92/7% and 34/60%. Evaluation of biochemical cure was hampered by lack of uniform reporting of relevant outcome measures. We suggest mandatory reporting of surgical outcomes using the PASO criteria for all units performing surgery for PA.

Purpose The aim of the study was to examine subjective health-related quality of life (HRQoL) in patients undergoing adrenalectomy. Methods The study included patients scheduled for adrenalectomy 2014–2017 after giving informed consent. The SF-36 questionnaire was administrated before operation and 1 year postoperatively. Results were compared with published normative values in Sweden. Results Some 50 patients were included. SF-36 scores for the whole cohort improved significantly after adrenalectomy in all dimensions except for bodily pain. Compared with the general Swedish population, the patients reported a significantly reduced HRQoL before and after adrenalectomy in all domains except for bodily pain postoperatively. Patients with benign functional tumours had lower HRQoL in physical domains before adrenalectomy than patients with benign non-functional tumours; Physical Component Summary (PCS), median 33.1 (range 17.1–62.9) vs. 44.2 (20.0–66.5), p = 0.018. Postoperatively, HRQoL was similar in the two groups of patients. Patients with benign functional tumours reported significantly improved HRQoL in all dimensions after adrenalectomy: PCS 33.1 (17.1–62.9) preoperatively vs. 47.6 (19.8-57.3) postoperatively, p = 0.005; Mental Component Summary (MCS) 33.8 (11.8–62.0) preoperatively vs. 52.7 (16.4–59.8) postoperatively, p = 0.004. These improvements were not seen in patients with benign non-functional or malignant tumours. Patients with malignant tumours reported no difference in SF-36 scores before or after adrenalectomy compared with patients with benign non-functional tumours. Conclusions Adrenalectomy improved HRQoL in patients with benign functional tumours. Adrenalectomy did not improve HRQoL in patients with benign non-functional tumours or in patients with malignant tumours.

Prophylactic central neck dissection in patients with papillary thyroid carcinoma is controversial. Sentinel node biopsy might be an adjunct to optimize surgical treatment for these patients. Earlier studies reported inconsistent detection rates and diagnostic value of this technique, and the role of sentinel lymph node biopsy in thyroid cancer needs to be established. During a single-center prospective interventional study between 2010 and 2017, sentinel lymph node biopsy using 99mTc-nanocolloidal albumin tracer was performed on patients undergoing thyroid surgery for suspected thyroid cancer by fine needle aspiration cytology. All eligible patients without clinical lymph node involvement were invited to participate. Central neck dissection was performed on all patients after the detection of sentinel lymph nodes. Ninety-six patients participated in the study. The detection rates of the sentinel node were 67% and 45% by scintigraphy and intraoperative gamma probe, respectively. The detection rate was not associated with Bethesda score, malignancy, or presence of lymph node metastases. Sensitivity, negative predictive value, and accuracy were 80%, 97%, and 98%, respectively, for the sentinel node to represent the status of lymph node metastasis in the central neck compartment. The false negative rate was 20%. Sentinel lymph node biopsy had a low detection rate and only moderate sensitivity in patients with suspected thyroid carcinoma and is not a useful adjunct to surgery in the context of current treatment concepts.

Patients with neuroendocrine tumors (NETs) are often treated with somatostatin analogs (SSAs) for control of symptoms and tumor growth. Such therapy could theoretically lead to misinterpretation of somatostatin receptor imaging with 68Ga-DOTATATE PET/CT by interfering with tracer-receptor binding. Guidelines recommend an interval of 3-4 wk between the last dose and imaging. The aim of this study was to evaluate if long-acting (LA) SSA treatment changes the uptake of 68Ga-DOTATATE in patients with NETs. Methods: From 2013 to 2016, 296 patients with, or under evaluation for, NETs were included in this prospective observational study. The effect of LA SSA on tracer uptake was evaluated in 2 main patient populations: those undergoing 68Ga-DOTATATE PET/CT before starting LA SSA treatment and at least once afterward, and those receiving ongoing LA SSA therapy, in whom the effect of the interval between the last dose of LA SSA and the PET/CT exam was analyzed. A third, explorative, analysis was performed to evaluate if clinical disease progression, regression, or stable tumor status changed the uptake of 68Ga-DOTATATE. In the 3 analyses, measurements of SUVmax in normal liver and tumor lesions were compared. Results: The median SUVmax in normal liver was significantly higher before treatment (8.6; interquartile range, 7.4-10.2) than after treatment initiation (6.0; 4.7-8.0) (P < 0.001). No significant changes in SUVmax were seen in tumor lesions after treatment initiation. No significant differences in SUVmax were found in normal liver or tumor lesions dependent on the interval between last dose of LA SSA and PET/CT. Conclusion: Treatment with LA SSA does not change SUVmax in tumor lesions, whereas SUVmax in normal liver is significantly lower after treatment. The findings have implications for interpretation of 68Ga-DOTATATE PET/CT for response assessment after SSA therapy and for guidelines on discontinuation of treatment before PET/CT.

Context The prevalence of autoimmune disorders in individuals with 21-hydroxylase deficiency (21OHD) is unclear. The gene responsible, CYP21A2, is located in a highly immunologically active region. Objective To study the prevalence of autoimmune disorders in individuals with 21OHD. Design, Setting, and Participants Patients with 21OHD (n = 714) were compared with controls matched for sex, year, and place of birth (n = 71,400). Data were derived by linking National Population-Based Registers. Subgroup analyses were performed regarding phenotype and CYP21A2 genotype. Main Outcome Measures Number and type of autoimmune disorders. Results Mean age (± SD) was 29.8 ± 18.4 years. Individuals with 21OHD had more autoimmune disorders than did controls [7.4% vs 5.1%, P < 0.01; relative risk (RR) 1.47 (95% CI, 1.13 to 1.91)], especially male patients [6.8% vs 4.1%, P < 0.05; RR, 1.64 (95% CI, 1.08 to 2.49)], whereas it did not reach significance for female patients [7.9% vs 5.8%, P = 0.068; RR, 1.37 (95% CI, 0.98 to 1.92)]. Among the specific autoimmune groups and disorders, autoimmune endocrine disorders and autoimmune thyroid disorders, including Graves disease, were significantly increased in the entire cohort of patients and for male and female patients separately. Inflammatory bowel disease (IBD) and systemic connective tissue disorders did not reach significant levels for the entire cohort (P = 0.075 and 0.05, respectively), but male patients were more affected by IBD (P = 0.022). The groups with milder phenotypes and genotypes seemed to be more affected by autoimmune disorders. Conclusions 21OHD was associated with an increased prevalence of autoimmune disorders. The relatively young age of the patient cohort and possible protective effects by glucocorticoid treatment may have underestimated the risk.

Non-classic congenital adrenal hyperplasia (NCAH) is a relatively common disorder regardless of ethnicity, but most cases are never diagnosed, especially in males. A baseline 17-hydroxyprogesterone measurement may be used for screening, but 17-hydroxyprogesterone measurement after ACTH stimulation is the gold standard. We advocate a CYP21A2 mutation analysis to verify the diagnosis, for genetic counselling and for better prognostic and treatment guidance. Most patients are diagnosed in adolescence and adult life with hirsutism, acne, a PCOS-like picture and fertility issues. Many men with NCAH never seek medical attention and escape diagnosis. Although treatment is somewhat controversial, an early diagnosis and start of treatment may have positive implications on growth and be relevant for preventing and ameliorating the symptoms and consequences of androgen excess that develop over time, including fertility issues. Long-term treatment with glucocorticoids will improve the androgen symptoms but may result in long-term complications, such as obesity, insulin resistance, hypertension, osteoporosis and fractures. The glucocorticoid doses should be kept low. However, complications seen in NCAH, assumed to be caused by the glucocorticoid treatment, may also be associated with long-term androgen exposure. Oral contraceptive pills are a common treatment option for young females with NCAH. Regular clinical monitoring to improve the clinical outcome is recommended. It is important to acknowledge that glucocorticoid treatment will lead to secondary cortisol insufficiency and the need for stress dosing. Studies focusing on the specific difficulties patients with NCAH face, both those with a late clinical diagnosis and those with a neonatal diagnosis obtained by screening, are warranted.

Objective To identify cross-border international registries for rare endocrine conditions that are led from Europe and to understand the extent of engagement with these registries within a network of reference centres (RCs) for rare endocrine conditions. Methods Database search of international registries and a survey of RCs in the European Reference Network for rare endocrine conditions (Endo-ERN) with an overall response rate of 82%. Results Of the 42 conditions with orphacodes currently covered within Endo-ERN, international registries exist for 32 (76%). Of 27 registries identified in the Orphanet and RD-Connect databases, Endo-ERN RCs were aware of 11 (41%). Of 21 registries identified by the RC, RD-Connect and Orphanet did not have a record of 10 (48%). Of the 29 glucose RCs, the awareness and participation rate in an international registry was highest for rare diabetes at 75 and 56% respectively. Of the 37 sex development RCs, the corresponding rates were highest for disorders of sex development at 70 and 52%. Of the 33 adrenal RCs, the rates were highest for adrenocortical tumours at 68 and 43%. Of the 43 pituitary RCs, the rates were highest for pituitary adenomas at 43 and 29%. Of the 31 genetic tumour RCs, the rates were highest for MEN1 at 26 and 9%. For the remaining conditions, awareness and participation in registries was less than 25%. Conclusion Although there is a need to develop new registries for rare endocrine conditions, there is a more immediate need to improve the awareness and participation in existing registries.

Aim Population studies have shown an increased risk of neurodevelopmental disorders in males born with the congenital condition hypospadias, where the opening of the urethra is on the underside of the penis. We investigated overall psychiatric morbidity in cases and matched controls. Methods This study compared 167 men born with hypospadias from 1959 to 1994 in Stockholm or Gothenburg in Sweden using hospital registers. They were compared with controls from the Swedish population registry, who were contacted by regular mail and students who were recruited by local advertisements. The total sample had a mean age of 33.5 years (range: 19-54). They completed self-rating scales for depressive, anxiety and obsessive-compulsive symptoms and symptoms of attention deficit hyperactivity disorder. In addition, 33 cases and 47 controls underwent psychiatric morbidity interviews that covered the 17 most common psychiatric diagnoses. Results A fifth (21%) of both the cases and controls reported current or previous psychiatric symptoms. There were no significant differences in self-rated depression, anxiety or obsessive-compulsive disorder symptoms between the patients and controls or between the different phenotype groups. The distribution was not significantly affected by the severity of hypospadias. Conclusion Psychiatric morbidity was no higher in men with hypospadias than population-based controls.

Introduction Patients with midgut neuroendocrine tumours (NETs) suffer from decreased health-related quality of life (HRQoL), in large part due to bowel symptoms. However, it is unknown which bowel symptoms affect HRQoL the most. An enhanced understanding of this is essential to better focus treatment on this aspect of the disease. This study aimed to determine which bowel symptoms affect HRQoL the most in patients with midgut NETs. Methods Consenting patients with midgut NET completed the Memorial Sloan Kettering Bowel Function Instrument and the HRQoL questionnaire (EORTC QLQ-C30). The correlation between bowel symptoms and HRQoL was analysed using multiple linear regression, adjusting for age, Charlson Comorbidity Index score, presence of metastatic disease, chromogranin A, and BMI yielding ß-coefficients with 95% confidence intervals. Results Totally, 119 patients with midgut NET completed the questionnaires and were included in the study. Loose stool and bowel frequency ≥ 3/day were the most common bowel symptoms, reported by 47% and 56% of patients, respectively. However, sensitivity to certain types of food and beverages, a feeling of incomplete emptying of the bowel, and soiling were the symptoms most strongly correlated with decreased HRQoL, especially within domains concerning role and social function, with ß-coefficients for the strongest correlated symptoms of 15.0 and 14.6, respectively. Discussion While symptoms concerning stool consistency and frequency are common in patients with midgut NET, our study suggests that other, more socially stigmatising symptoms affect patients’ HRQoL more. Our findings could help caregivers understand patients’ perceptions of the disease and provide avenues for more directed therapies.

Newborn screening for congenital adrenal hyperplasia (CAH) using 17-hydroxyprogesterone (17-OHP) as an indicator of disease was first introduced in the 1970s [...]

Contains fulltext : 232500.pdf (Publisher’s version ) (Open Access) Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is a disorder of adrenal steroid biosynthesis, leading to hypocortisolism, hypoaldosteronism, and hyperandrogenism. Impaired quality of life (QoL) has been demonstrated in women with CAH, but data on men with CAH are scarce. We hypothesized that disease severity and poor treatment control are inversely associated with QoL. In this study, 109 men (16-68 years) with 21OHD were included. The WHOQOL-BREF questionnaire was used to measure self-reported QoL domain scores on a 0-100 scale, where higher scores reflect better QoL. QoL domain scores were compared to published data on healthy and chronically ill reference populations from France, Germany, the Netherlands, and the United Kingdom. Differences in QoL scores among groups of disease severity and treatment control were tested within the study population. Overall, the men with CAH in this study appeared to rate their QoL as good. Median domain scores were 78.6 (IQR: 67.9-85.7) for physical health, 79.2 (IQR: 66.7-87.5) for psychological health, 75.0 (IQR: 58.3-83.3) for social relationships, and 81.3 (IQR: 71.9-90.6) for environment. In general, these scores were similar to WHOQOL-BREF domain scores in healthy references and higher compared to chronically ill reference populations. The domain scores did not differ among genotype groups, but patients with undertreatment or increased 17-hydroxyprogestrone concentrations scored higher on several QoL domains (p

Patients' perceptions on quality of care and gaps in diagnosis/management of rare endocrine diseases (RED) were collected in a 21-item questionnaire, answered on-line in the patients' language. There were 598 (66% females) responses from 29 countries reflecting pituitary, adrenal, thyroid, parathyroid, gonadal, genetic and autoimmune diseases. While in 36% a diagnosis was made in 5 years. In 64% it took 2-7 professionals for a correct diagnosis, after which in >50% a specialist/specific treatment was available within 1 month; 60% were satisfied with current treatment. Most (59-67%) would have liked access to psychological support, social worker, dietician or physiotherapist/rehabilitation specialists. Half were satisfied with information received, treatment and health care follow-up; 87% contacted patient/support groups; 78% agreed that "The personal limitations related to the disease, impact on my everyday quality of life". Conclusion: Diagnostic delay in RED is still unsatisfactory in Europe, as well as specific needs impacting QoL.

Context Congenital adrenal hyperplasia (CAH) is a common monogenic recessive disorder. It has been suggested that CYP21A2 deficiency is common because carriers may have a survival advantage, 1 in 15,000 in most populations. Carriers of CYP21A2 mutations typically do not have clinical symptoms but have a defined phenotype with a more prompt cortisol response to ACTH. Objective We investigated whether the mortality was lower, and determined the cause of death in carriers and population controls. Design A total of 1143 obligate carriers of a CYP21A2 mutation (561 men) were identified from the Swedish National CAH Registry, encompassing >700 patients and the Multi-Generation Registry to identify their parents. The mortality and cause of death were identified through the Swedish Cause of Death Registry. The hazard ratios (HRs) and 95% CIs were calculated. The results were compared with controls from the general population, matched for sex and age. Results The overall mortality was lower in carriers of a CYP21A2 mutation compared with the controls (HR 0.79; 95% CI, 0.678 to 0.917; P = 0.002). The difference was more marked among carriers of a more severe mutation. Infection as the cause of death was significantly lower (HR 0.65; 95% CI, 0.48 to 0.87; P < 0.01), particularly for death in pneumonia (HR 0.22; 95% CI, 0.06 to 0.88; P = 0.03). The lower overall mortality among women compared with men in the general population was confirmed among both carriers and controls. Conclusion Obligate CYP21A2 carriers of a classic mutation had a reduced mortality. Specifically, a possible reduced mortality due to pneumonia was seen.

Congenital adrenal hyperplasia (CAH) has been associated with brain structure alterations, but systematic studies are lacking. We explore brain morphology in 37 (21 female) CAH patients and 43 (26 female) healthy controls, aged 16–33 years, using structural magnetic resonance imaging to estimate cortical thickness, surface area, volume, subcortical volumes, and white matter (WM) microstructure. We also report data on a small cohort of patients (n = 8) with CAH, who received prenatal dexamethasone (DEX). Patients with CAH had reduced whole brain volume (4.23%) and altered structure of the prefrontal, parietal, and superior occipital cortex. Patients had reduced mean FA, and reduced RD and MD, but not after correcting for brain volume. The observed regions are hubs of the visuospatial working memory and default mode (DMN) networks. Thickness of the left superior parietal and middle frontal gyri was associated with visuospatial working memory performance, and patients with CAH performed worse on this task. Prenatal treatment with DEX affected brain structures in the parietal and occipital cortex, but studies in larger cohorts are needed. In conclusion, our study suggests that CAH is associated with brain structure alterations, especially in the working memory network, which might underlie the cognitive outcome observed in patients.

Context Patients with classic congenital adrenal hyperplasia (CAH) are treated postnatally with lifelong glucocorticoid (GC) replacement therapy. Previous results on general cognitive ability in individuals with CAH have been conflicting. Objective To evaluate long-term cognitive effects of GC replacement therapy and the impact of early diagnosis in children with CAH. Design and Setting Observational study with patients from a single research institute. Patients 32 children with CAH (mean age 11.5 years) identified through the Swedish national neonatal screening program for CAH and 52 matched population controls (mean age 10.7 years). Eleven (6 female) children with CAH who were treated prenatally with dexamethasone (DEX), (CAH-DEX) (mean age 11.7 years). Intervention GC replacement therapy, neonatal screening for CAH. Measures Cognitive abilities assessed with standardized neuropsychological tests (Wechsler scales, Span Board Test, Stroop Interference Test, NEPSY list learning). Results Children with CAH (not prenatally treated) performed equally well as population controls on a series of tests assessing general intellectual ability and executive functions. No significant differences were observed in cognitive performance between patients with different genotypes (null, non-null). Patients with salt-wasting CAH performed poorer than patients with simple virilizing CAH in a test assessing visuo-spatial working memory (P = 0.039), although the performance was within the normal range for the population. Prenatally DEX-treated girls with CAH had lower verbal intellectual ability compared with CAH girls not exposed to prenatal treatment (P = 0.037). Conclusion Children and adolescents with CAH who were diagnosed early via a neonatal screening program and treated with hydrocortisone had normal psychometric intelligence and executive functions.

Papillary thyroid cancer is treated with total/near-total thyroidectomy (TT) with or without central lymph node dissection (CLND), depending on risk factors and tumour size. Balancing the risk of disease recurrence and surgical morbidity remains a challenge. A population-based nationwide study was undertaken to evaluate the risk of permanent hypoparathyroidism associated with CLND.Data on patients with stage pT1-3 papillary thyroid cancer, who underwent TT with or without CLND between 1 July 2004 and 30 June 2014 were retrieved from the Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal Surgery. Drug use was ascertained by cross-linking with the Swedish Prescribed Drug Register. Permanent hypoparathyroidism was defined as treatment with active D vitamin or oral calcium drugs for more than 6 months after surgery. Data were analysed separately for all patients and those who underwent TT + CLND. Univariable and multivariable logistic regression analyses were done, yielding odds ratios (ORs) with 95 per cent confidence intervals.A total of 722 patients were included in the study. Permanent hypoparathyroidism was more common in the TT + CLND group than the TT group: 30 of 265 patients (6·6 per cent) versus six of 457 (2·3 per cent) (P = 0·011). In multivariable logistic regression analysis, CLND was a risk factor for permanent hypoparathyroidism (OR 3·74, 95 per cent c.i. 1·46 to 9·59, based on use of combined therapy 6 months after surgery). In patients who had TT + CLND, node negativity was associated with a risk of permanent hypoparathyroidism (OR 3·08, 1·31 to 7·25).CLND is an independent risk factor for permanent hypoparathyroidism. Node negativity is associated with a higher risk of permanent hypoparathyroidism.El carcinoma papilar de tiroides se trata mediante tiroidectomía (thyroidectomy, TT) con o sin vaciamiento ganglionar cervical central (central lymph node dissection, CLND) dependiendo de los factores de riesgo y del tamaño del tumor. La valoración del equilibrio entre el riesgo de recidiva de la enfermedad y la morbilidad quirúrgica sigue siendo un desafío. Se llevó a cabo un estudio de base poblacional ampliado a toda una nación para evaluar el riesgo de hipoparatiroidismo permanente asociado a CLND. MÉTODOS: Los datos de los pacientes con cáncer papilar de tiroides, estadio pT1-3, tratados quirúrgicamente mediante TT con o sin CLND del 1 de julio de 2004 al 30 de junio de 2014, se recogieron a partir del registro escandinavo de calidad de cirugía tiroidea, paratiroidea y suprarrenal (Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal surgery, SQRTPA). El uso de fármacos se evaluó por información cruzada del registro nacional de prescripción de fármacos. El hipoparatiroidismo permanente se definió como necesidad de tratamiento con vitamina D activa o preparados de calcio orales durante más de 6 meses tras la cirugía. Se analizaron los datos de todos los pacientes y de los operados mediante TT+CLND por separado, utilizando análisis univariados y regresiones logísticas multivariables, expresando los resultados mediante la razón de oportunidades (odds ratio, OR) y los i.c. del 95%.La población de estudio estaba formada por 722 pacientes. El hipoparatiroidismo permanente fue más frecuente en el grupo de TT-CLND (n = 30, 6,6%) que en el grupo de TT (n = 6, 2,3%), P = 0,011. En el modelo de regresión logística, el CLND era un factor de riesgo de hiperparatiroidismo permanente, OR 3,74 (i.c. del 95% 1,46-9,59). En los pacientes operados mediante TT-CLND, la negatividad de los ganglios linfáticos se asoció con un riesgo de hipoparatiroidismo permanente, OR 3,08 (i.c. del 95% 1,31-7,25). CONCLUSIÓN: El vaciamiento ganglionar cervical central es un factor de riesgo independiente de hipoparatiroidismo permanente. La negatividad de los ganglios linfáticos se asociaba con un aumento del riesgo de hiperparatiroidismo permanente.

Background Contemporary patients with primary hyperparathyroidism are often diagnosed with mildly raised serum calcium levels. Previous studies have reported increased mortality in patients with primary hyperparathyroidism. This retrospective cohort study aimed to examine whether contemporary patients operated for primary hyperparathyroidism have higher mortality than the general population, and whether mortality in these patients is associated with serum calcium concentration, adenoma weight or multiglandular disease. Methods Patients from a Swedish national cohort consisting of patients registered in the Scandinavian Quality Register for Thyroid, Parathyroid, and Adrenal Surgery 2003–2013, were matched with population controls. The National Patient Register, the Swedish Cause of Death Register, and socioeconomic data were cross-linked. End of follow-up was 10 years after surgery, 31 December 2015, or emigration. Mortality was analysed by standardized mortality ratio, Kaplan–Meier survival estimates, and univariable and multivariable Cox regression. Multiple imputation by chained equations was performed on missing data. Results After exclusions, there were 5009 patients with primary hyperparathyroidism and 14 983 controls. Multivariable Cox regression analysis adjusted for age, sex, Charlson Co-morbidity Index, marital status, level of education, disposable income, and period of surgery showed lower mortality in patients than controls (hazard ratio (HR) 0.83, 95 per cent c.i. 0.75 to 0.92). In univariable Cox regression of mortality in patients, serum calcium concentration (mmoles per litre) was associated with mortality (HR 2.20, 1.53 to 3.16). This association remained in multivariable Cox regression after multiple imputation (HR 1.79, 1.19 to 2.70). Conclusion Mortality was not increased in patients operated for primary hyperparathyroidism compared with controls in a contemporary setting. Preoperative serum calcium concentration might, however, influence survival.

Congenital adrenal hyperplasia (CAH) was the fourth disorder added to the national Swedish neonatal screening program in 1986, and approximately 115,000 newborns are screened annually. Dried blood spot (DBS) screening with measurement of 17-hydroxyprogesterone (17OHP) is also offered to older children moving to Sweden from countries lacking a national DBS screening program. Here, we report an update on the CAH screening from January 2011 until December 2019. Results: During the study period, 1,030,409 newborns and 34,713 older children were screened. In total, 87 newborns were verified to have CAH, which gives an overall positive predictive value (PPV) of 11% and 21% for term infants. Including the five missed CAH cases identified during this period, this gives an incidence of 1:11,200 of CAH in Sweden. Among the older children, 12 of 14 recalled cases were found to be true positive for CAH. All patients were genotyped as part of the clinical follow-up and 70% of the newborns had salt wasting (SW) CAH and 92% had classic CAH (i.e., SW and simple virilizing (SV) CAH). In the group of 12 older children, none had SW CAH and two had SV CAH. Conclusion: The incidence of classic CAH is relatively high in Sweden. Early genetic confirmation with CYP21A2 genotyping has been a valuable complement to the analysis of 17OHP to predict disease severity, make treatment decisions and for the follow-up and evaluation of the screening program.

Background EuRRECa (European Registries for Rare Endocrine Conditions) is a group of web-based projects that work closely with the European Reference Network (ERN) for Rare Endocrine Conditions (endo-ern.eu) and helps the ERN with inventorying its clinical activity. To understand the number of new encounters of rare conditions within this network, it has launched an e-reporting programme for rare endocrine conditions (e-REC) that are covered within this network. Methods 46 endocrine centres within 18 countries volunteered to participate in e-REC from July 2018 to June 2019. An electronic reporting ‘card’ developed through REDcap was issued monthly to enquire whether clinicians had encountered a new case of any condition within the 8 Endo-ERN main thematic groups (MTGs). Results On a monthly basis over 1 year, a median of 14 (range 11, 21) paediatric centres and 13 (11, 25) adult centres actively reported cases. A median of 53 (22, 80) paediatric cases and 96 (42, 250) adult cases were reported monthly. Amongst paediatric cases, conditions within the Sex Development and Maturation (SDM) theme were most commonly reported comprising 38% of all reported conditions, with XY, DSD being the most commonly reported condition (24% of cases). Amongst adults, Pituitary and Thyroid conditions were most commonly reported, 34% and 26% of all conditions, respectively. Amongst conditions within the Pituitary group, pituitary adenoma was the most commonly reported condition (74% of cases) and non-metastatic thyroid carcinoma was the most commonly reported condition (95% of cases) amongst the Thyroid group. In children, the median number of cases reported per centre was 21 (9, 32) for conditions affecting SDM. In adults, a median of 37 (6, 75) Pituitary and 22 (5, 80) Thyroid cases were reported per centre. Conclusion e-REC is a simple, yet effective, platform that can be used to capture information on new encounters with patients with several rare conditions and can be adapted to serve the needs of other discrete networks that are interested in understanding the occurrence of rare conditions.

Background Patients with disorders/differences of sex development (DSD), especially those possessing the Y chromosome, have a higher risk of gonadal germ-cell tumours (GCTs). We aimed to examine the incidence of different types of gonadal neoplasia and associated risk factors. Methods A total of 1040 DSD patients aged ≥16 years participated in a cross-sectional multicentre European study (dsd-LIFE). Data on medical history were gathered from the patients’ archival medical documents. A web-based questionnaire was filled out individually by the participants. A physical examination was performed in all, while ultrasonography of gonads was carried out in 214 and semen analysis was performed for 53 patients. Results Germ-cell neoplasia was present in 12 % of patients with DSD and in 14 % of those with XY DSD. The highest risk (36 %) was observed in 46,XY patients with gonadal dysgenesis (GD): complete GD (33 %) and partial GD (23 %), but also in mixed GD (8 %) and complete androgen insensitivity syndrome (AIS) (6%). It was not reported in partial AIS, XX male, 46,XX DSD and congenital adrenal hyperplasia, Turner and Klinefelter syndromes, or in androgen biosynthesis defects. Benign sex cord-stromal tumours (Sertoli- and Leydig-cell tumours) were noted only in patients with complete AIS (3.1 %) and Klinefelter syndrome (14.3 %). A relationship between risk factors for GCT and gonadal neoplasia appearance, other than the Y chromosome, was not found. Conclusion Adult patients with GD and the Y chromosome have the highest risk of GCT and should be kept under thorough medical control and receive special medical follow-up to prevent the development of gonadal tumours.

Context Standardized description of external genitalia is needed in the assessment of children with atypical genitalia. Objectives To validate the External Genitalia Score (EGS), to present reference values for preterm and term babies up to 24 months and correlate obtained scores with anogenital distances (AGDs). Design, Setting A European multicenter (n = 8) validation study was conducted from July 2016 to July 2018. Patients and Methods EGS is based on the external masculinization score but uses a gradual scale from female to male (range, 0–12) and terminology appropriate for both sexes. The reliability of EGS and AGDs was determined by the interclass correlation coefficient (ICC). Cross-sectional data were obtained in 686 term babies (0–24 months) and 181 preterm babies, and 111 babies with atypical genitalia. Results The ICC of EGS in typical and atypical genitalia is excellent and good, respectively. Median EGS (10th to 90th centile) in males < 28 weeks gestation is 10 (8.6–11.5); in males 28–32 weeks 11.5 (9.2–12); in males 33–36 weeks 11.5 (10.5–12) and in full-term males 12 (10.5–12). In all female babies, EGS is 0 (0-0). The mean (SD) lower/upper AGD ratio (AGDl/u) is 0.45 (0.1), with significant difference between AGDl/u in males 0.49 (0.1) and females 0.39 (0.1) and intermediate values in differences of sex development (DSDs) 0.43 (0.1). The AGDl/u correlates with EGS in males with typical genitalia and in atypical genitalia. Conclusions EGS is a reliable and valid tool to describe external genitalia in premature and term babies up to 24 months. EGS correlates with AGDl/u in males. It facilitates standardized assessment, clinical decision-making and multicenter research.

The Bethesda system for cytopathology (TBSRTC) is a 6-tier diagnostic framework developed to standardize thyroid cytopathology reporting. The aim of this study was to determine the risk of malignancy (ROM) for each Bethesda category. Thyroidectomy-related data from 314 facilities in 22 countries were entered into the following outcome registries: CESQIP (North America), Eurocrine (Europe), SQRTPA (Sweden) and UKRETS (UK). Demographic, cytological, pathologic and extent of surgery data were mapped into one dataset and analyzed. Out of 41,294 thyroidectomy patient entries from January 1, 2015, to June 30, 2017, 21,746 patients underwent both thyroid FNA and surgery. A comparison of cytology and surgical pathology data demonstrated a ROM for Bethesda categories 1 to 6 of 19.2%, 12.7%, 31.9%, 31.4%, 77.8% and 96.0%, respectively. Male patients had a higher rate of malignancy for every Bethesda category. Secondary analysis demonstrated a high ROM in male patients with Bethesda 3 category aged 31–35 years (52.1%, 95% confidence interval (CI) 37.9–66.2%), aged 36–40 years (55.9%, 95% CI 39.2–72.6%) and aged 41–45 years (46.9%, 95% CI 33–60.9%). Patients with Bethesda 5 and 6 scores were more likely to undergo total thyroidectomy (65.9% and 84.6%); for patients with Bethesda scores 2 and 3, a higher percentage of females underwent total thyroidectomy compared to males in spite of a higher ROM for males. These data demonstrate that Bethesda categories 1–4 are associated with a higher ROM compared to the first edition of TBSRTC, especially in male patients, and validate findings from the second edition of TBSRTC.

The term differences of sex development (DSDs; also known as disorders of sex development) refers to a heterogeneous group of congenital conditions affecting human sex determination and differentiation. Several reports highlighting suboptimal physical and psychosexual outcomes in individuals who have a DSD led to a radical revision of nomenclature and management a decade ago. Whereas the resulting recommendations for holistic, multidisciplinary care seem to have been implemented rapidly in specialized paediatric services around the world, adolescents often experience difficulties in finding access to expert adult care and gradually or abruptly cease medical follow-up. Many adults with a DSD have health-related questions that remain unanswered owing to a lack of evidence pertaining to the natural evolution of the various conditions in later life stages. This Consensus Statement, developed by a European multidisciplinary group of experts, including patient representatives, summarizes evidence-based and experience-based recommendations for lifelong care and data collection in individuals with a DSD across ages and highlights clinical research priorities. By doing so, we hope to contribute to improving understanding and management of these conditions by involved medical professionals. In addition, we hope to give impetus to multicentre studies that will shed light on outcomes and comorbidities of DSD conditions across the lifespan., Differences of sex development (DSDs) comprise a large group of congenital conditions of the urogenital tract and reproductive system. This Consensus Statement summarizes recommendations for clinical indications, diagnosis and management of patients with a DSD.

Testicular adrenal rest tumors (TARTs) are presumably derived from ectopic adrenocortical tissue in the testis, affecting up to 49% to 94% of males with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. Few reports have described TARTs in rarer forms of CAH such as 3β-hydroxysteroid dehydrogenase type 2 deficiency (3βHSD2D). A man with 3βHSD2D presented with massive bilateral testicular tumors. He had been treated with glucocorticoids and mineralocorticoids since infancy, with difficulties in suppressing dehydroepiandrosterone sulfate. At the age of 13 years, bilateral testicular lumps were found, and a radiologic diagnosis of TARTs was proposed. Subsequent sonographic examinations showed progression, despite intensifying his glucocorticoid therapy with metabolic complications. Following an open testicular biopsy, concerns of a Leydig cell tumor and risk of malignant transformation were raised, and because the patient also had local symptoms and azoospermia, he underwent bilateral orchiectomy at age 33 years. Histopathology was consistent with bilateral TARTs, exhibiting widespread immunoreactivity for adrenocortical markers, whereas no histological features of Leydig cell tumors were seen. The distinction between TARTs and Leydig cell tumors is important but can be challenging, and in our case, orchiectomy was needed to rule out the latter diagnosis. TART should be considered a differential diagnosis also in patients with 3βHSD2D who have testicular lumps., This case report is a 34-year follow-up of a patient with 3βHSD2D who had infertility due to extensive bilateral TARTs and underwent bilateral orchiectomy at age 33 years.

Overall survival for patients with small intestinal neuroendocrine tumours (siNETs) is long, even with metastatic disease, making quality of life issues relevant. The impact of surgery on quality of life is not known. We investigated determinants of health-related quality of life in patients who had undergone surgery for a siNET. Patients operated for a siNET between 1998 and 2016 at Skane University Hospital (Lund, Sweden), who were alive in February 2017, were sent two questionnaires constructed by the European Organisation for Research and Treatment of Cancer (EORTC QLQ-C30, EORTC QLQ-GINET21). Global quality of life, physical function, disease-related worries, diarrhoea and endocrine symptoms were evaluated with linear and logistic regression in relation to patient-, tumour- and treatment-related factors. Statistical analysis was performed using STATA 11®. One hundred patients (84%) completed the questionnaires. Women had worse global quality of life (p = 0.019), more disease-related worries (p

Dexamethasone (DEX) is used to prevent prenatal virilization in female fetuses with congenital adrenal hyperplasia (CAH). Since treatment has to be started before the genotype of the fetus is known, 7 out of 8 fetuses will be exposed to DEX without benefit. Previously, we have observed negative effects on cognition and behavior in DEX treated children. Here we evaluated neuropsychological functions, psychopathology and autistic traits in non-CAH DEX-treated adults exposed during the first trimester of fetal life (duration 6.2 ± 2.2 weeks). Cognitive functions, psychopathology and autistic traits were compared between DEX-treated subjects (n = 23) and non-exposed controls (n = 58). Cognitive outcome was also evaluated longitudinally for DEX-treated participants. We used neuropsychological tests (Wechsler Scales and the Stroop Interference Test) and questionnaires assessing executive functions (the Barkley Deficit in Executive Functioning Scale), psychopathology (the Montgomery Åsberg Depression Ratings Scale, the Hospital Anxiety and Depression Scale, the Liebowitz Social Anxiety Scale) and autistic traits (Autism Quota). We did not observe any significant differences in cognition, psychopathology or autistic traits between DEX-treated individuals and population controls. A significant improvement in verbal working memory (p = 0.038) and in impulse inhibition (p = 0.011) was seen when subjects were evaluated longitudinally. In summary, first-trimester DEX-exposed adult individuals do not show any significant neuropsychological deficits nor an increase in anxiety, depression or autistic traits, compared with a control group from the general population. The results also suggest that the observed deficits in executive functioning during childhood may improve with time.

Background: Previous studies in quality of life (QOL) in individuals with disorders/differences of sex development (DSD) have been restricted to subpopulations of the condition. We describe QOL in adult persons with DSD compared to country specific references and assess the impact of diagnosis.Methods: The multicentre cross-sectional clinical evaluation (dsd-LIFE) took place in 14 specialized clinics in six European countries. Adolescents (≥16 years) and adults having a DSD condition were included from 02/2014 to 09/2015. The main outcome QOL was measured by the WHOQOL-BREF (domains of physical health, psychological, social relationships, and environment). QOL was compared to country specific reference populations by using unpaired t-tests. Linear regression models explained the additional variance of the diagnosis on QOL.Results: Three hundred one individuals with Turner Syndrome, 219 with Klinefelter Syndrome (including XYY), 226 with 46,XX CAH and 294 with rare DSD conditions (gonadal dysgenesis, androgen insensitivity syndrome, severe hypospadias, and androgen synthesis errors or other diagnosis) took part. Compared to healthy European populations, QOL was similar in psychological, slightly worse in physical health, and slightly better in environment. In social relationships, QOL was significantly poorer compared to healthy and non-healthy reference populations. In linear regression models health status was the most important predictor of QOL; additional variance was explained by feelings about household's income in all domains, and the relationship status in social relationships. Diagnosis explained nearly no additional variance.Conclusions: Except for social relationships, most people with DSD adapt well to their life circumstances and report a good QOL. Not diagnosis, but the individual's health status is much more important than previously thought. Therefore care for people with DSD should focus more on chronic physical or mental health problems both related and unrelated to the diagnosis itself.Trial registration: German Clinical Trials Register DRKS00006072.

Introduction Hypoparathyroidism is the most common complication following thyroidectomy. There are few population-based reports on the rate of hypoparathyroidism in children. The incidence of medical treatment of permanent hypoparathyroidism in children is reported using a national registry. Methods The study population included patients below 18 years of age undergoing total thyroidectomy reported to the Scandinavian Quality Registry for Thyroid, Parathyroid and Adrenal Surgery 2004–2014. Patients with previous thyroid or parathyroid surgery or treatment with vitamin D before surgery were excluded from analysis. Permanent postoperative hypoparathyroidism was defined as treatment with vitamin D for more than 6 months after thyroidectomy. Risk factors for permanent hypoparathyroidism were calculated with uni- and multivariable logistic regression. Using data from the Swedish Inpatient Registry, rates of readmissions and annual number of days in hospital after total thyroidectomy were compared between patients with and without permanent hypoparathyroidism. Results Some 274 children (215 girls and 59 boys) underwent total thyroidectomy. The median age was 14 (range 0–17) years. Indications for surgery were Graves’ disease (214, 78.1%), other benign disease (27, 9.9%) and thyroid cancer (33, 12%). Median follow-up was 4.8 years. Twenty (7.3%) children developed permanent hypoparathyroidism. No statistically significant risk factors for permanent hypoparathyroidism were identified. Rates of readmission and annual number of days in hospital after discharge were similar in patients with and without permanent hypoparathyroidism. Conclusions The rate of permanent hypoparathyroidism following total thyroidectomy in children was high and is a cause of concern.

Background: Complete and partial androgen insensitivity syndrome (CAIS, PAIS) are associated with an increased risk of gonadal germ cell cancer (GGCC). Recent guidelines recommend gonadectomy in women with CAIS in late adolescence. Nevertheless, many adult women prefer to retain their gonads. Aims: This study aims to explore attitudes towards gonadectomy in AIS in centres around the world, estimate the proportion of adults with retained gonads and/or who developed GGCC, and explore reasons for declining gonadectomy. Methods: A survey was performed among health care professionals who use the International DSD Registry (I-DSD). Results: Data were provided from 22 centres in 16 countries on 166 women (CAIS) and 26 men (PAIS). In CAIS, gonadectomy was recommended in early adulthood in 67% of centres; 19/166 (11.4%) women refused gonadectomy. Among 142 women who had gonadectomy, evidence of germ cell neoplasm in situ (GCNIS), the precursor of GGCC, was reported in 2 (1.4%) out of 8 from whom pathology results were formally provided. Nine out of 26 men with PAIS (34.6%) had retained gonads; 11% of centres recommended routine gonadectomy in PAIS. Conclusion: Although development of GGCC seems rare, gonadectomy after puberty is broadly recommended in CAIS; in PAIS this is more variable. Overall, our data reflect the need for evidence-based guidelines regarding prophylactic gonadectomy in AIS.
