Bruck syndrome is an autosomal recessive disease characterised by the clinical combination of both osteogenesis imperfecta and arthrogryposis multiplex congenita (AMC). It is caused due to collagen miss-folding and cross-linking defect resulting from a deletion in FKBP10 (OMIM #259450) and/or PLOD2

An asymptomatic woman aged 24 years was informed about the presence of a heart murmur by her attending obstetrician while she was hospitalised for a spontaneous abortion 6 months ago and was subsequently referred to us to rule out underlying heart disease. After clinical examination and relevant laboratory evaluation, a diagnosis of severe valvular pulmonary stenosis (PS) was established. Interestingly, our patient had undergone an open thoracotomy for surgical closure of a patent ductus arteriosus (PDA) under general anaesthesia 12 years ago in the absence of any appreciable shunt across the ligated ductus at present. Considering the severe gradient across her pulmonary valve, she underwent a successful percutaneous balloon pulmonary valvuloplasty (PBPV) procedure with excellent haemodynamic outcome. The pertinent literature concerning the rare combination of PDA in association with PS as well as the technicalities of PBPV procedure in an adult are discussed.

Background Children and adolescents with fragile X syndrome (FXS) manifest significant symptoms of anxiety, particularly in response to face-to-face social interaction. In this study we used functional near-infrared spectroscopy (fNIRS) to reveal a specific pattern of brain activation and habituation in response to face stimuli in young girls with FXS, an important but understudied clinical population. Methods Participants were 32 girls with FXS (age: 11.8 ± 2.9 years) and a control group of 28 girls without FXS (age: 10.5 ± 2.3 years) matched for age, general cognitive function and autism symptoms. Functional NIRS was used to assess brain activation during a face habituation task including repeated upright/inverted faces and greeble (nonface) objects. Results Compared to the control group, girls with FXS showed significant hyper-activation in the frontopolar and dorsal lateral prefrontal cortices in response to all face stimuli (upright + inverted). Lack of neural habituation (and significant sensitization) was also observed in the FXS group in the frontopolar cortex in response to upright face stimuli. Finally, aberrant frontopolar sensitization in response to upright faces in girls with FXS was significantly correlated with notable cognitive-behavioral and social-emotional outcomes relevant to this condition including executive function, autism symptoms, depression and anxiety. Conclusions These findings strongly support a hypothesis of neural hyper-activation and accentuated sensitization during face processing in FXS, a phenomenon that could be developed as a biomarker endpoint for improving treatment trial evaluation in girls with this condition.

Coexistence of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency and Turner Syndrome (TS) is rare. We report a 6-year-old Portuguese girl with mosaic TS [45,XO(39)/47,XXX(21)] presented with premature pubarche at the age of 5 years. Laboratory findings showed elevated 17-hydroxyprogesterone, dehydroepiandrosterone sulfate, androstenedione and total testosterone, and sex-determining region Y (SRY) was negative. CYP21A2 gene analysis revealed two mutations (c.[844G>T]; [CYP21A2del]), consistent with the non-classical form of CAH. Complete deletion of CYP21A2 allele occurred de novo. At 6 years and 4 months, she presented accelerated growth velocity and hydrocortisone at the dose of 5 mg/m2/day was initiated. This case highlights the need to perform global examinations looking for virilization signs in TS patients follow-up. It also supports the reported genetic combination of TS and CAH. Therefore, CAH should be kept in mind in TS patients with SRY negative and virilization signs, even in the absence of short stature.

Coarctation of the aorta, a stenotic disease of the juxtaductal aorta, causes upper extremity hypertension, lower extremity hypoperfusion, and various degrees of left ventricular hypertrophy or left ventricular failure depending on the tightness of the coarcted segment, the age at presentation, and associated cardiac lesions. Patients with coarctation of the aorta can be categorized into three major groups: (1) Patients with isolated coarctation (the greater majority), which can be associated with a bicuspid aortic valve; (2) Patients with coarctation and ventricular septal defect (VSD); (3) Patients who have associated complex heart disease, including truncus arteriosus, transposition of the great arteries, double outlet ventricles, or heterotaxy syndrome.

Aims. The relationship of tumour volume, radiotherapy treatment time and other prognostic factors affecting prognosis was evaluated. Methods. 184 patients with locally advanced head and neck cancer were treated with radical intensity modulated radiotherapy (IMRT) and compared retrospectively. Results. In the multivariate analysis the overall survival was dependent on gross tumour volume (GTV), clinical stage (CS), radiotherapy treatment time (RTT) and p16 status. Local control was influenced by GTV, overall RTT and age. DFS was significantly affected by GTV, CS, RTT, p16 status and concomitant chemotherapy (CHT). Conclusions. The tumour volume and the radiotherapy treatment time were the most significant prognostic factors with the best outcomes in patients with GTV ≤ 55 cc and RTT ≤ 48 days (mean LC 8.1, DFS 7.1 and OS 6.4 years) and worst outcomes with GTV > 55 cc and RTT >48 days (mean LC 4.4, mean DFS 3.2 and mean OS 2.6 years).

Early-onset forms of hereditary spastic paraplegia and inborn errors of metabolism that present with spastic diplegia are among the most common "mimics" of cerebral palsy. Early detection of these heterogenous genetic disorders can inform genetic counseling, anticipatory guidance, and improve outcomes, particularly where specific treatments exist. The diagnosis relies on clinical pattern recognition, biochemical testing, neuroimaging, and increasingly next-generation sequencing-based molecular testing. In this short review, we summarize the clinical and molecular understanding of: 1) childhood-onset and complex forms of hereditary spastic paraplegia (SPG5, SPG7, SPG11, SPG15, SPG35, SPG47, SPG48, SPG50, SPG51, SPG52) and, 2) the most common inborn errors of metabolism that present with phenotypes that resemble hereditary spastic paraplegia.

Objective Tricuspid annular size reduction with annuloplasty rings represents the foundation of surgical repair of functional tricuspid regurgitation. However, the precise effect of annular size reduction on leaflet motion and geometry remains unknown. Methods Ten sheep underwent surgical implantation of a pacemaker with an epicardial lead and were paced 200-240 beats/min to achieve biventricular dysfunction and functional tricuspid regurgitation. Subsequently, sonomicrometry crystals were implanted on the right ventricle, the tricuspid annulus, and on the belly of anterior, posterior, and septal tricuspid leaflets. Double-layer polypropylene suture was placed around the tricuspid annulus and externalized to a tourniquet. Simultaneous echocardiographic, hemodynamic, and sonomicrometry data were acquired with functional tricuspid regurgitation and during 5 consecutive annular reduction steps. Annular area, tenting height, and volume, together with each leaflet strain, radial length, and angles, were calculated from crystal coordinates. Results Rapid pacing reduced both left ventricle and right ventricle function and induced functional tricuspid regurgitation (0-3+) in all animals (from 0 ± 0 to 2.4 ± 0.7, P = .002), whereas tricuspid annulus diameter increased from 2.6 ± 0.3 cm to 3.3 ± 0.3 cm (P = .001). Tricuspid annular size reduction 1 to 5 resulted in 16% ± 7%, 37% ± 11%, 55% ± 11%, 66% ± 10%, and 76% ± 8% tricuspid annulus area reduction, respectively, and successively decreased tricuspid regurgitation. Tricuspid annular size reduction 2 to 5 induced anterior and posterior leaflet restricted motion and lower diastolic motion velocities. Tricuspid annular size reduction 5 perturbed septal leaflet range of motion but preserved its angle velocities. Tricuspid annular size reduction 3-5 generated compressive strains in all leaflets. Conclusions Tricuspid annular area reduction of 55% perturbed anterior and posterior leaflet motion while maintaining normal septal leaflet movement. More extreme reduction triggered profound changes in anterior and posterior leaflet motion, suggesting that aggressive undersizing impairs leaflet kinematics.

In 1961, K Merendino ‘in pure curiosity’, while tracking the murmur of mitral regurgitation, placed his stethoscope ‘on the vertex of the head’, and ultimately led to a medical curiosity and exam finding that not only bears his name, but awes medical learners at all stages of their careers. Merendino and colleagues collected seven such cases of the ‘Murmur on Top of the Head’ building on the work of others who provided a detailed description of mitral regurgitation and noted murmur radiation to the neck and cervical/lumbosacral spine. The majority of patients suffered from rheumatic heart disease or subacute bacterial endocarditis in native heart valves. Here, we report on a case of the ‘Murmur on Top of the Head’ and provide the reader/listener with a direct recording of the ‘Merendino murmur’ (as well as its spinal correlate) in an elderly woman with a bioprosthetic mitral valve.

Neonatal hyperbilirubinaemia is a very common entity witnessed in most of the newborns. Rarely are there events where the bilirubin levels reach extreme values mandating invasive therapy. Unconjugated hyperbilirubinaemia when solely present is easy to manage and diagnose the common aetiological factors associated with it. The issue arises when we come across a mixed picture of conjugated with unconjugated hyperbilirubinaemia and puts us in a dilemma as to what are we treating. Our case highlights a similar picture where we witnessed the highest documented levels of total bilirubin but to our surprise the major component of which was direct bilirubin. This report takes us through the differentials which were ruled out and our management strategies for solving this rare mystery.

Background Patients with Fontan circulation may develop heart failure resulting in atrial fibrillation during the late phase. Inotropic effects to ameliorate hemodynamics on the Fontan circulation are not well understood, especially when in atrial fibrillation. This study was performed to determine whether dobutamine therapy in patients with Fontan circulation has limited effects on improving hemodynamics. Methods Lumped computational models (sinus and atrial fibrillation) were employed including biventricular, atriopulmonary connection (APC), and extracardiac total cavopulmonary connection (TCPC) Fontan models. The condition of atrial fibrillation including lack of atrial beat, irregular ventricular contraction, and time-varying elastance for the ventricle was introduced. A different dose of dobutamine was given by varying the elastance of the ventricle, heart rate, and peripheral resistance. Results In all models, the cardiac output decreased by 22.5% to 25.8% in atrial fibrillation. At 10 μg/kg/min of dobutamine in sinus rhythm, the cardiac output increased by 32.3% in the biventricular model but by only 9.2% (p Conclusions In the Fontan circulation, atrial fibrillation itself reduced the cardiac output by approximately 25%, and dobutamine had a limited effect on increasing the cardiac output, especially when in atrial fibrillation. Maintaining sinus rhythm in patients with Fontan circulation is very important.

The widespread presence of microplastics (MPs) in the environment has led to the rise of the study on the interaction between MPs and microorganisms. The variety and characteristics of MPs in the environment make their interaction with microorganisms more complex. Recent studies have found that MPs can also serve as an important carrier for microorganisms to form fully developed biofilms on the substrates. The emergence of new ecological sites will also affect the ecosystem of water and soil. We present the latest knowledge of MPs' interactions with microorganisms and summarize their respective potential impacts on the environment. It was found that the main factors affecting microbial colonization on MPs were the characteristics of MPs, exposure time and environmental factors. Furthermore, microbial colonization on MPs can affect the composition and distribution of the microbial community in the environment, as well as the migration and transformation of other contaminants which also occur in the animal guts. When it come to the toxicity of MPs to microorganisms, it has been found that the main effects of MPs on microorganisms are the effect on microbial growth, photosynthesis of microorganisms and some single cells. In addition, the combined effects of MPs with heavy metals and organic compounds on microorganisms can be divided into antagonistic effects, synergistic toxicity, promoting effects and non-effects. In turn, microbes will have impacts on MPs in terms of degradation, absorption, transfer and deposition. In practical application, MPs will affect the biological treatment stage of sewage treatment. This review discusses the interaction mechanism and influencing factors between microorganisms and MPs. It also called for active exploration of methods for treating MPs with microorganisms in the actual environment, providing a theoretical basis for the treatment of microorganisms, and a better understanding of the environmental behavior and ecological risk assessment of MPs.

Objective To develop an insight scale for Prader-Willi Syndrome (PWS), a genetically determined neurodevelopmental disorder with different psychopathological and behavioural problems. Methodology A sample of 36 PWS patients (58.3% women) attended at the Endocrinological Department of the Corporacio Sanitaria Parc Tauli (Sabadell, Barcelona) was evaluated. Insight was assessed by means of an adapted version of the Scale of Unawareness of Mental Disorder (SUMD), including three general insight dimensions: awareness of having a PWS, awareness of the effects of psychopharmacological medication and awareness of the social consequences, as well as three items that assess awareness of each particular symptom of the disease (obesity/overweight, excessive appetite and excessive food intake). Results The final Scale included six items and demonstrated an adequate internal consistency (Cronbach Alfa of 0.857 for Caregivers and 0.798 for Clinicians) but a high inter-rate variability. External validation using an Analytical-Visual Insight Scale was adequate. Conclusions The Adapted version for Prader-Willi patients of the Scale of Unawareness of Mental Disorder (APW-SUD) showed adequate psychometric properties and it is an easy to administer means to assess insight in this population.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant genetic disease characterised by systemic hamartomas or benign tumours which affects multiple organs including brains, kidneys, heart, liver, eyes, lungs and skin due to inappropriate activation of mammalian target of rapamycin (mTOR)

To report a sporadic case of a familial adenomatous polyposis (FAP) discovered in a patient with bilateral retinal pigment epithelial lesions.Case report.A 30-year-old Asian woman presented for evaluation of bilateral pigmented lesions at the level of the retinal pigment epithelium. She had no personal or family history of colonic polyps or colon cancer. Colonoscopy revealed innumerable adenomatous polyps and genetic testing revealed a mutation in the adenomatous polyposis coli gene consistent with FAP. She subsequently underwent prophylactic total colectomy.The pigmented retinal pigment epithelium lesions of FAP have a characteristic appearance and it is vital for the retinal specialist to be familiar with them. De novo mutations in the APC gene are responsible for 20% to 30% of FAP cases. In the presence of the characteristic retinal pigment epithelium lesions, it is important to send the patient for work up of FAP even in the absence of family history of FAP.

The quality of care for patients admitted with a primary diagnosis of gout, both before and after admission, has not been systematically examined.To understand national trends in hospital admission for a primary diagnosis of gout in Aotearoa New Zealand over the past 10 years and the quality of care for gout received by these patients before and after the admission.Data from the Aotearoa New Zealand National Collections from 1 January 2007 to 31 December 2019 were analysed to determine rates of hospital admission for a primary diagnosis of gout. Admission data include cost-weight analysis, as well as quality of care data including gout-specific medication dispensing in the year prior and year after admission.There were 13 721 admissions with a primary diagnosis of gout over the analysis period, with an average cost per admission in 2019 of NZ$4301. The rate of admission per 100 000 population was highest in Pacific peoples followed by Māori. Although dispensing of any allopurinol increased in the year after admission, rates of regular allopurinol dispensing remained low; 38.1% for admissions in 2018. Patients who were younger (especially 20-44 years), not enrolled in a primary health organisation before admission and female had lower rate of regular allopurinol after admission.In this nationwide study, rates of admission for gout were highest in Pacific peoples and in Māori. Rates of regular allopurinol dispensing were low even after admission for a primary diagnosis of gout. These findings highlight the need for improvements in gout management in Aotearoa New Zealand, including in post-discharge planning from secondary care inpatient services.

This study investigated a 2-stage arterial switch operation (ASO) to treat transposition of the great arteries (TGA) with intact ventricular septum (TGA-IVS) in late referral patients.We retrospectively analyzed patients with TGA-IVS or TGA with restricted ventricular septal defects who had undergone 2-stage ASO at our institution from February 2007 to August 2018. Included were 41 patients: 21 (51.2%) who had undergone long-term 2-stage ASO and 20 (48.8%) who had undergone rapid 2-stage ASO.The long-term 2-stage group was older at ASO (3.5 vs 25 months; P.001). Results were more satisfactory in the long-term group than in the rapid group for intensive care unit time (P = .004), mechanical ventilation time (P = .004), and length of stay (P = .007). No in-hospital death occurred in the long-term group, and the postoperative course was more manageable in the long-term group than in the rapid group. However, the risk of significant neoaortic regurgitation was lower in the rapid group, which also had a better left ventricular ejection fraction.The long-term group achieved better early-term outcomes than the rapid group. However, a high risk of neoaortic regurgitation and myocardial dysfunction was also noted.

The hypoglossal canal (HC) is an unusual location of the posterior fossa dural arteriovenous fistula (AVF), which usually occurs in the transverse or sigmoid sinus. Herein, we report a case of HC dural AVF successfully treated with transvenous coil embolization using detachable coils in a 68-year-old woman who presented with headache and left pulsatile tinnitus for 2 months. Brain magnetic resonance imaging (MRI) and cerebral angiography revealed left HC dural AVF. The pulsatile bruit disappeared immediately after the procedure. Follow-up MRI showed complete disappearance of the fistula. Precise localization of the fistula through careful consideration of the anatomy and transvenous coil embolization using a detachable coil can facilitate the treatment for HC dural AVF.

Prader-Willi syndrome (PWS) is characterized by hypotonia, distinctive facial features, hyperphagia, obesity, short stature, hypogonadism, intellectual disability, and behavior problems. Uncontrolled hyperphagia can lead to dangerous food-seeking behavior and with life-threatening obesity. Severe obesity is prone to obstructive sleep apnea (OSA) and can lead to cor pulmonale. This study reports on a case involving a 21-year-old man with PWS who developed OSA due to severe obesity, which led to cor pulmonale, a life-threatening complication. Multidisciplinary care provided in the intensive care unit included weight reduction, ventilation support, antipsychotics, sedative drugs, rehabilitation, and meticulous skin care. The patient did recover. To prevent severe obesity in adults with PWS, hyperphagia must be controlled, and the patient must also be managed by an endocrinologist throughout childhood.

Summary Aim Comparison of gender personality traits in CAH-affected 46,XX patients with those in 46,XY patients with complete androgen insensitivity syndrome (AIS) or gonadal dysgenesis (GD). Patients and methods Thirty-six 46,XX CAH, three 46,XY AIS, four 46, XY GD patients. The Bem Sex-Role Inventory (BSRI) was used to measure masculinity, femininity and to research gender roles. Results The lowest femininity values were in the patients with CAH, the highest in patients with AIS. Age at study was not associated with the value of BSRI score. CAH patients with the Prader score 4 had lower median femininity score values than those who had the Prader score 3, however, the difference was statistically insignificant. Conclusion More masculinizied personality behavioral traits in females with CAH most likely result from exposure of the fetal brain to high levels of androgens.

Objective Alar batten grafts are used to treat in nasal valve dysfunction (NVD). They can be placed by open or closed rhinoplasty using rib, septal, or auricular concha cartilage. Our surgical team used a modified placement of the classic alar batten.We aim to describe these changes and to the technique and demonstrate that modified alar batten grafts can improve the effects of spreader grafts and classic alar batten grafts. Methods A retrospective study of 91 functional rhinoplasties was performed from March 2011 to November 2019 at a public university hospital in Murcia. The patients were divided into three groups. Group A included patients operated on using spreader grafts, group B included patients operated on using spreader grafts associated with alar batten grafts fixed to the caudal edge of the lateral crura of the lower lateral cartilage (LLC), and group C included patients operated on using modified alar batten grafts. Results A total of 91 functional rhinoplasties were performed, 31 patients were operated on in group A, 27 patients were operated on in group B, and 33 patients were operated on in group C. The success rate was 67.7% in group A, 70.4% in group B and 93.9% in group C. Conclusion Modified alar batten grafts achieved better results than spreader grafts and spreader grafts associated with classic alar batten grafts. The size, position and placement of the sutures of modified alar batten grafts were the key factors in improving our results.

Charcot-Marie-Tooth disease (CMT) is a common hereditary peripheral polyneuropathy encompassing distinct monogenetic disorders. Pathogenic mutations in mitofusin 2 (MFN2) are the most frequent cause of its axonal type, CMT type 2A, with diverse phenotypes. We herein report a Japanese patient with a novel heterozygous MFN2 pathogenic variant (c.740 G>C, p.R247P) and severe CMT phenotypes, including progressive muscle weakness, optic atrophy, urinary inconsistency, and restrictive pulmonary dysfunction with eventration of the diaphragm that developed over her 60-year disease course. Our case expands the clinico-genetic features of MFN2-related CMT and highlights the need to evaluate infrequent manifestations during long-term care of CMT patients.

The aim of this study was to evaluate the incidence, severity, and treatment modalities of retinopathy of prematurity (ROP) in moderate and late preterm infants with a gestational age (GA)31 + 6 weeks.ROP screening results of preterm infants with GA31 + 6 weeks to 36 + 6 weeks between March 2013 and January 2019 were evaluated retrospectively. Infants were divided into 2 groups according to GA as 32-33 + 6 weeks (moderate preterm) and 34-36 + 6 weeks (late preterm). In these groups, any ROP and severe ROP (requiring treatment) development rates and ROP types and treatment modalities were evaluated.A total of 4156 preterm infants, 1875 (45.1%) female and 2281 (54.9%) male, were included. Overall, 1466 (35.2%) of the infants were moderate preterm and 2690 (64.8%) were late preterm. The incidences of any ROP and severe ROP were 22% and 2.5%, respectively. The rate of severe ROP was 5.3% in moderate preterm infants and 0.9% in late preterm infants. Significant correlations were determined between duration of hospital stay, birth weight (BW), and GA with ROP development (r = +0.415, r = -0.258, r = -0.199, respectively; p0.001 for all). Of 102 patients (2.5%) requiring treatment, 64 (62.7%) had laser, 34 (33.3%) had intravitreal bevacizumab (IVB), 2 (1.9%) had sequential IVB and laser, and 2 (1.9%) had vitreoretinal surgery.ROP seems to still be an important health problem in moderate and late preterm infants in our country according to data from screening high-risk preterm infants with a GA31 + 6 weeks. In this cohort, ROP development correlates with GA, BW, and duration of hospitalization significantly.

Purpose To validate the performance of postnatal growth and retinopathy of prematurity (G-ROP) screening criteria in a Taiwanese cohort. Design Screening evaluation with retrospective data Method Premature infants who underwent retinopathy of prematurity (ROP) screening between January 2015 and April 2019 at a tertiary hospital were examined. Infants with known final ROP results and complete longitudinal weight records were included. G-ROP screening criteria, both original and simplified (G-ROP 180 g), were applied as the prediction model for type 1 ROP; sensitivity and specificity were analyzed. The reduction in the number of infants requiring ROP screening and the number of funduscopic examinations were calculated. Result A total of 303 infants with documented ROP outcomes and complete weight gain records were examined; 103 infants developed ROP, of whom 29 developed type 1 ROP, while the other 200 did not develop ROP. For the detection of type 1 ROP, the sensitivity and specificity of the original G-ROP screening criteria were 96.6% and 42.3%, and 100% and 31% for the simplified G-ROP 180 g model, respectively. The reduction in the number of infants requiring screening and funduscopic examinations was 32.6% and 33.5% for the original G-ROP criteria, and 28.1% and 23.2% for the G-ROP 180 g model, respectively. Conclusion Both the original G-ROP and G-ROP 180 g criteria attained high sensitivities in detecting type 1 ROP in the current Taiwanese cohort, with the G-ROP 180 g model outperforming the original one. Validation and modification may be required before applying G-ROP screening criteria to different populations.

BACKGROUND: There remains controversy regarding the outcomes resulting from treatment versus conservative management of patent ductus arteriosus (PDA) among preterm infants. The effects of extreme prematurity, hemodynamic status of the PDA, and age at treatment remain poorly defined. STUDY DESIGN: This retrospective case-control study including infants

Unifocalization of the major aorto-pulmonary collaterals (MAPCAs) followed by intra-cardiac repair with ventricular septal defect (VSD) closure and restoration of right ventricle to pulmonary artery (RV-PA) continuity is the ultimate treatment goal in a case of VSD with pulmonary atresia (PA) and MAPCAs. It may be achieved in a single stage or may require multiple surgeries. We present a case of a 2 year old boy with VSD/PA who underwent single stage unifocalization of MAPCAs through midline followed by intra-cardiac repair using two polytetrafluoroethylene (PTFE) tube grafts; one for unifocalization and other as a bicuspid valved RV-PA conduit.

OBJECTIVE: The study objective was to analyze survival and incidence of Fontan completion of patients with single-ventricle and concomitant unbalanced atrioventricular septal defect. METHODS: Data from 4 Dutch and 3 Belgian institutional databases were retrospectively collected. A total of 151 patients with single-ventricle atrioventricular septal defect were selected; 36 patients underwent an atrioventricular valve procedure (valve surgery group). End points were survival, incidence of Fontan completion, and freedom from atrioventricular valve reoperation. RESULTS: Median follow-up was 13.4 years. Cumulative survival was 71.2%, 70%, and 68.5% at 10, 15, and 20 years, respectively. An atrioventricular valve procedure was not a risk factor for mortality. Patients with moderate-severe or severe atrioventricular valve regurgitation at echocardiographic follow-up had a significantly worse 15-year survival (58.3%) compared with patients with no or mild regurgitation (89.2%) and patients with moderate regurgitation (88.6%) (P = .033). Cumulative incidence of Fontan completion was 56.5%, 71%, and 77.6% at 5, 10, and 15 years, respectively. An atrioventricular valve procedure was not associated with the incidence of Fontan completion. In the valve surgery group, freedom from atrioventricular valve reoperation was 85.7% at 1 year and 52.6% at 5 years. CONCLUSIONS: The long-term survival and incidence of Fontan completion in our study were better than previously described for patients with single-ventricle atrioventricular septal defect. A concomitant atrioventricular valve procedure did not increase the mortality rate or decrease the incidence of Fontan completion, whereas patients with moderate-severe or severe valve regurgitation at follow-up had a worse survival. Therefore, in patients with single-ventricle atrioventricular septal defect when atrioventricular valve regurgitation exceeds a moderate degree, the atrioventricular valve should be repaired. ispartof: JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY vol:163 issue:3 pages:1166-1175 ispartof: location:United States status: published

The present study included the first case of mucopolysaccharidosis (MPS) type VII in Taiwan. During pregnancy, the patient was diagnosed with hydrops fetalis and had ascites aspiration 4 times. In the following years, she presented gradually with chronic lung disease, developmental delay, short stature, dysmorphic features of coarse face, macroglossia and pigeon chest with scoliosis. Upon referral at age 4 years, she had corneal clouding, mild limitation of range of motion (ROM) and hepatosplenomegaly. X-ray showed paddle ribs and dysplastic vertebral bodies. MPS was suspected and urine glycosaminoglycans (GAGs) elevated were noted. The leukocyte enzymatic analyses for MPS I, MPS II, MPS IIIB, MPS IVA, and MPS VI were all normal. Afterward, the molecular analysis showed two heterozygous genetic variants of c.104C > A and c.1454C > T in trans in the GUSB gene ( NM_000181.4 ) which were the causes for MPS VII. Then, we checked the leukocyte β-glucuronidase activity for MPS VII and showed extremely low, therefore confirmed the diagnosis. Clinicians should increase the awareness on the early signs of MPS to have a prompt diagnosis and offer the correct treatment like enzyme replacement therapy (ERT) as early as possible.

Fanconi syndrome is a functional disorder of the proximal tubule, characterized by pan-aminoaciduria, glucosuria, hypophosphatemia, and metabolic acidosis. With the advancements in gene analysis technologies, several causative genes are identified for Fanconi syndrome. Several mitochondrial diseases cause Fanconi syndrome and various systemic symptoms; however, it is rare that the main clinical symptoms in such disorders are Fanconi syndrome without systematic active diseases like encephalomyopathy or cardiomyopathy. In this study, we analyzed two families exhibiting Fanconi syndrome, developmental disability and mildly elevated liver enzyme levels. Whole-exome sequencing (WES) detected compound heterozygous known and novel BCS1L mutations, which affect the assembly of mitochondrial respiratory chain complex III, in both cases. The pathogenicity of these mutations has been established in several mitochondria-related functional analyses in this study. Mitochondrial diseases with isolated renal symptoms are uncommon; however, this study indicates that mitochondrial respiratory chain complex III deficiency due to BCS1L mutations cause Fanconi syndrome with developmental disability as the primary indications.

Background Repair of complete atrioventricular septal defect with absent or diminutive primum defect is challenging because of atrial septal malposition and abnormal anatomy of the left atrioventricular valve. We sought to define the incidence, anatomy, and surgical outcomes of this entity. Methods We identified all patients in our institutional database presenting for complete atrioventricular septal defect repair from 2006 to 2018. Operative reports and echocardiograms were reviewed to determine the presence and size of the primum defect, atrioventricular valve anatomy, degree of atrioventricular valve regurgitation, repair method, and complications, including reoperation for atrioventricular valve regurgitation. Functionally univentricular patients and those receiving repair at an outside institution were excluded. Results Of 183 patients with complete atrioventricular septal defect, absent/diminutive primum defect occurred in 16 patients (8.7%; 10 absent, 6 diminutive). Six patients (38%) had leftward malposition of the atrium septum on the common atrioventricular valve. The rate of reoperation for left atrioventricular valve regurgitation was 31% (3 early, 2 late), for which preoperative predictors included leftward malposition of the atrial septum onto the common atrioventricular valve (4/6 patients with malposition required reoperation, P = .036, Fisher exact test). One patient exhibiting this risk factor died. The overall rate of moderate or greater left atrioventricular valve regurgitation on the most recent postoperative echocardiogram was 13% (2/16 patients; median follow-up, 141 days; range, 3-2236 days). Conclusions Complete atrioventricular septal defect with absent or diminutive primum defect is a unique variant of complete atrioventricular septal defect for which the risk of reoperation for left atrioventricular valve regurgitation after complete repair is high and risk factors include leftward malposition of the atrial septum on the common atrioventricular valve.

Immunohistochemistry (IHC) and/or MSI-PCR (microsatellite instability-polymerase chain reaction) tests are performed routinely to detect mismatch repair deficiency (MMR-D). Classical MMR-D tumors present a loss of MLH1/PMS2 or MSH2/MSH6 with MSI-High. Other profiles of MMR-D tumors have been described but have been rarely studied. In this study, we established a classification of unusual MMR-D tumors and determined their frequency and clinical impact. All MMR-D tumors identified between 2007 and 2017 were selected. Any profile besides the classical MMR-D phenotype was defined as unusual. For patients with unusual MMR-D tumors, IHC, and PCR data were reviewed, the tumor mutation burden (TMB) was evaluated and clinical and genetic features were collected. Of the 4948 cases of MMR testing, 3800 had both the available IHC and MSI-PCR results and 585 of these had MMR-D. After reviewing the IHC and PCR, 21% of the cases initially identified as unusual MMR-D were reclassified, which resulted in a final identification of 89 unusual MMR-D tumors (15%). Unusual MMR-D tumors were more often associated with non-CRC than classical MMR-D tumors. Unusual MMR-D tumors were classified into four sub-groups: i) isolated loss of PMS2 or MSH6, ii) classical loss of MLH1/PMS2 or MSH2/MSH6 without MSI, iii) four MMR proteins retained with MSI and, iv) complex loss of MMR proteins, with clinical characteristics for each sub-group. TMB-high or -intermediate was shown in 96% of the cancers studied (24/25), which confirmed MMR deficiency. Genetic syndromes were identified in 44.9% (40/89) and 21.4% (106/496) of patients with unusual and classical MMR-D tumors, respectively (P

The primary aim of this study is to compare the preoperative risk factors and postoperative outcomes between Charcot neuroarthropathy patients with dislocation versus purely fracture pattern breakdown. The secondary aim is to compare the same factors between Charcot neuroarthropathy patients with dislocation versus fracture-dislocation pattern breakdown. A total of 55 patients with forefoot, midfoot, or hindfoot Charcot Neuroarthopathy were assessed at a mean follow up of 2.99 years. Bivariate analysis compared preoperative risk factors and postoperative outcomes, and segmented multivariable regression analysis was performed. Dislocation pattern Charcot had statistically significant higher rates of broken hardware (p = .05), mean age (p = .01), and revisional exostectomy (p = .01) compared to pure fracture pattern Charcot. Dislocation pattern Charcot was 12 times more likely to have revisions exostectomy (odds ratio [OR] 12.0, 95% confidence interval [CI] 1.84-78.37), and was 8 times more likely to have osteomyelitis (OR 7.8, 95% CI 1.4-42.7, p = .02) compared to the fracture-dislocation pattern Charcot. The patients with pure fracture pattern Charcot were 58.8 times more likely to have Charcot breakdown involvement of the talonavicular joint compared to the dislocation pattern cohort (OR 58.83, 95% CI 1.1-3220.3). Involvement of the talonavicular joint, in the fracture pattern Charcot associate with medial column collapse occurring at the onset of Charcot breakdown. The dislocation pattern in Charcot Neuroarthropathy demonstrated a higher propensity for residual collapse as demonstrated by the higher rates of broken hardware, osteomyelitis, and need for revisional exostectomy.

Sickle cell disease (SCD) is the most common hereditary blood disorder in the United States. SCD is frequently associated with osteonecrosis, osteoporosis, osteopenia, and other bone-related complications such as vaso-occlusive pain, ischemic damage, osteomyelitis, and bone marrow hyperplasia known as sickle bone disease (SBD). Previous SBD models have failed to distinguish the age- and sex-specific characteristics of bone morphometry. In this study, we use the Townes mouse model of SCD to assess the pathophysiological complications of SBD in both SCD and sickle cell trait. Changes in bone microarchitecture and bone development were assessed by using high-resolution quantitative micro–computed tomography and the three-dimensional reconstruction of femurs from male and female mice. Our results indicate that SCD causes bone loss and sex-dependent anatomical changes in bone. SCD female mice in particular are prone to trabecular bone loss, whereas cortical bone degradation occurs in both sexes. We also describe the impact of genetic knockdown of cathepsin K– and E-64–mediated cathepsin inhibition on SBD.

Previous studies identified nonneutralizing FVIII-specific antibodies in the circulation of severe and nonsevere hemophilia A (sHA and nsHA) patients without FVIII inhibitors and also in some healthy individuals. To gain a better understanding of the nature of these nonneutralizing antibody responses, we analyzed and compared anti-FVIII antibody signatures in 3 study cohorts: previously treated sHA as well as nsHA patients without FVIII inhibitors, and healthy donors. FVIII-binding IgM, IgG1-4, and IgA antibodies were differentiated, FVIII-specificity was assessed, and associated apparent affinity constants were determined. Our results indicate that the nonneutralizing FVIII-specific antibody response in all study cohorts is dominated by IgG1 and IgA. Prevalences, titers, and affinities of these nonneutralizing antibodies were higher in the hemophilia A cohorts than in healthy donors. Stratification for the anti-hepatitis C virus (HCV) antibody status demonstrated the presence of FVIII-specific IgA with elevated titers in sHA patients with an active or past HCV infection when compared with HCV antibody-positive nsHA patients or HCV antibody-negative patients and healthy donors. Increased titers and affinities of FVIII-specific IgG1 antibodies were observed in a considerable number of hemophilia A patients as opposed to healthy subjects independently of the patients’ anti-HCV antibody status. Overall, our findings support the hypothesis that the generation of nonneutralizing anti-FVIII antibodies in healthy individuals and in noninhibitor hemophilia A patients might be based on similar immune mechanisms. However, differences in prevalences, titers, and affinities of these antibodies indicate distinct differences in the antibody evolution between healthy individuals and patients.

The von Frey filament test (vF) is a mainstay of clinical examination. However, its results can be affected by touch speed and other potentially confounding factors. Moreover, the differences between two adjacent filament levels are too large to detect subtle changes. Active vF (AvF) was developed to induce in-depth sensory change. The present study hypothesized that AvF produces different patterns of fingertip sensation; consequently, it could be used as a new assessment tool for neural impairment. The aim of the study was to provide preliminary normative comparative vF and AvF data. This study prospectively examined 32 healthy participants, using AvF and vF. The index and the fifth finger volar pad were examined using AvF and vF, without visual stimulation. The correlation between AvF and vF measurements was evaluated. In addition, differences according to innervation zone, right versus left hand, and gender, and the correlation between AvF values and subjects' age were analyzed. Mean AvF value was significantly higher and had greater variance than vF (111.3 ± 46.9 vs. 24.1 ± 9.8; P 0.01). The Spearman correlation coefficient between AvF and vF was 0.341. Values were similar in the index and fifth fingers and right and left hands. However, values were significantly different between women and men. The correlation between age and AvF values was 0.259. AvF provided more precise values, with continuous units for tactile sensation, excluding tester-dependent factors. Furthermore, AvF and vF values may not be correlated.

BACKGROUND: Sickle cell disease (SCD) is a rare hemoglobinopathy which can result in chronic liver disease and cirrhosis. Patients with SCD have an increased risk of hematologic malignancy, but the prevalence of hepatocellular carcinoma (HCC) in this population is unknown. Herein, the association of SCD with HCC was examined using registry data. METHODS: The SEER-Medicare database was queried to identify patients diagnosed with HCC between 2000 and 2015, and further stratified by SCD status. Propensity matching was performed to examine cancer-related survival and treatment outcomes. RESULTS: Overall 56,934 patients with HCC were identified, including 81 patients with SCD. Patients with SCD more frequently had cirrhosis [48.1% (39/81) vs 23.5% (13,377/56,853), p

Rationale and Objective To assess the possibility of differentiating pulmonary carcinoids from hamartomas and typical from atypical carcinoids by means of 18F-FDG PET/CT. Materials and Methods We retrospectively reviewed 139 patients with pathologically proven pulmonary carcinoids and hamartomas who underwent 18F-FDG PET/CT before surgical resection. Receiver operating characteristics curves were calculated to determine the potential of SUVmax to discriminate between pulmonary carcinoids and hamartomas, typical and atypical carcinoids. The correlation between SUVmax and tumor size was analyzed by Spearman correlation analysis. Results SUVmax was significantly higher in pulmonary carcinoids than in hamartomas (p Conclusion 18F-FDG PET/CT might be a useful tool in the differential diagnosis of carcinoids and hamartomas, and can also distinguish atypical from typical carcinoids. This may facilitate improved selection of patients for surgical resection and radiological follow-up.

Mismatch repair-deficient (MMRD) brain tumors are rare among primary brain tumors and can be induced by germline or sporadic mutations. Here, we report 13 MMRD-associated (9 sporadic and 4 Lynch syndrome) primary brain tumors to determine clinicopathological and molecular characteristics and biological behavior. Our 13 MMRD brain tumors included glioblastoma (GBM) IDH-wildtype (n = 9) including 1 gliosarcoma, astrocytoma IDH-mutant WHO grade 4 (n = 2), diffuse midline glioma (DMG) H3 K27M-mutant (n = 1), and pleomorphic xanthoastrocytoma (PXA) (n = 1). Next-generation sequencing using a brain tumor-targeted gene panel, microsatellite instability (MSI) testing, Sanger sequencing for germline MMR gene mutation, immunohistochemistry of MMR proteins, and clinicopathological and survival analysis were performed. There were many accompanying mutations, suggesting a high tumor mutational burden (TMB) in 77%, but TMB was absent in one case of GBM, IDH-wildtype, DMG, and PXA, respectively. MSH2, MLH1, MSH6, and PMS2 mutations were found in 31%, 31%, 31% and 7% of patients, respectively. MSI-high and MSI-low were found in 50% and 8% of these gliomas, respectively and 34% was MSI-stable. All Lynch syndrome-associated GBMs had MSI-high. In addition, 77% (10/13) had histopathologically multinucleated giant cells. The progression-free survival tended to be poorer than the patients with no MMRD gliomas, but the number and follow-up duration of our patients were insufficient to get statistical significance. In the present study, we found that the most common MMRD primary brain tumor was GBM IDH-wildtype. The genetic profile of MMRD GBM was different from that of conventional GBM. MMRD gliomas with TMB and MSI-H may be sensitive to immunotherapy but resistant to temozolomide. Our findings can help develop better treatment options., The authors examined 13 mismatch repair-deficient (MMRD)-associated primary brain tumors to determine molecular characteristics and biological behavior. MMRD occurred after chemotherapy and radiotherapy in two cases. The genetic profile of MMRD glioblastoma was different from that of conventional glioblastoma. Half of the MMRD-gliomas and all Lynch syndrome-associated GBMs were high in microsatellite instability. These tumors had high mutational burdens and tended to have shorter progression-free survival than glioma without MMRD.

While cystic hepatic lesions are frequently encountered in clinical practice, differentiation amongst the various entities can prove difficult if the histologic pitfalls and diagnostic caveats are unknown. Many patients present with vague clinical symptoms and overlapping imaging findings. Herein we discuss the most commonly encountered cystic hepatic lesions including abscesses (pyogenic and amebic), echinococcal cyst, simple hepatic cyst, ciliated hepatic foregut cyst, intrahepatic pseudocyst, mucinous cystic neoplasm, hemangioma, angiosarcoma, multilocular cystic hepatocellular carcinoma, cystic metastatic lesions, hematoma, and biloma.

Prader–Willi syndrome (PWS) is a rare genetic syndrome, caused by the loss of expression of the paternal chromosome 15q11-q13 region. Over the past years, many cases of patients with characteristics similar to PWS, but without a typical genetic aberration of the 15q11-q13 region, have been described. These patients are often labelled as Prader–Willi-like (PWL). PWL is an as-yet poorly defined syndrome, potentially affecting a significant number of children and adults. In the current clinical practice, patients labelled as PWL are mostly left without treatment options. Considering the similarities with PWS, children with PWL might benefit from the same care and treatment as children with PWS. This review gives more insight into the pheno- and genotype of PWL and includes 86 papers, containing 368 cases of patients with a PWL phenotype. We describe mutations and aberrations for consideration when suspicion of PWS remains after negative testing. The most common genetic diagnoses were Temple syndrome (formerly known as maternal uniparental disomy 14), Schaaf–Yang syndrome (truncating mutation in the MAGEL2 gene), 1p36 deletion, 2p deletion, 6q deletion, 6q duplication, 15q deletion, 15q duplication, 19p deletion, fragile X syndrome, and Xq duplication. We found that the most prevalent symptoms in the entire group were developmental delay/intellectual disability (76%), speech problems (64%), overweight/obesity (57%), hypotonia (56%), and psychobehavioral problems (53%). In addition, we propose a diagnostic approach to patients with a PWL phenotype for (pediatric) endocrinologists. PWL comprises a complex and diverse group of patients, which calls for multidisciplinary care with an individualized approach.

Mismatch repair deficiency (dMMR) predicts response to immune checkpoint inhibitor therapy in solid tumors. Long mononucleotide repeat (LMR) markers may improve the interpretation of microsatellite instability (MSI) assays. Our cohorts included mismatch repair (MMR) proficient and dMMR colorectal cancer (CRC) samples, MMR proficient and dMMR endometrial cancer (EC) samples, dMMR prostate cancer samples, MSI-high (MSI-H) samples of other cancer types, and MSI-low (MSI-L) samples of various cancer types. MMR status was determined by immunohistochemical staining and/or MSI Analysis System Version 1.2 (V1.2). The sensitivity and specificity of the LMR MSI panel for dMMR detection were both 100% in CRC. The sensitivity values of the MSI V1.2 and LMR MSI panels in EC were 88% and 98%, respectively, and the specificity values were both 100%. The sensitivity of the LMR panel was 75% in dMMR prostate cancer detected by immunohistochemistry. The 22 samples of other cancer types that were previously classified as MSI-H were also classified as MSI-H using the LMR MSI panel. For the 12 samples that were previously classified as MSI-L, 1 sample was classified as microsatellite stable using the LMR MSI panel, 8 as MSI-L, and 3 as MSI-H. The LMR MSI panel showed high concordance to the MSI V1.2 panel in CRC and greater sensitivity in EC. The LMR MSI panel improves dMMR detection in noncolorectal cancers.

Purpose: Cerebellar tonsillar herniation (TH) occurs frequently in syndromic craniosynostosis; however, the exact pathogenesis is unknown. This study evaluates the association between skull base deformities and TH in syndromic craniosynostosis. Methods: Retrospective study MRI study comparing syndromic craniosynostosis to controls. Measured parameters included clivus length, skull base angle, Boogard's angle, foramen magnum area, and cerebellar tonsillar position (TP). The association between skull base parameters and TP was evaluated with linear mixed models, correcting for age and risk factors for TH in craniosynostosis (hydrocephalus, intracranial hypertension, craniocerebral disproportion, and lambdoid synostosis). Results: Two hundred and eighty-two scans in 145 patients were included, and 146 scans in 146 controls. The clivus was smaller at birth, and its growth was retarded in all syndromes. The skull base angle was smaller at birth in Apert and Crouzon syndromes, and the evolution through time was normal. Boogard's angle was smaller at birth in Apert syndrome, and its evolution was disturbed in Apert and Saethre-Chotzen syndromes. The foramen magnum was smaller at birth in Crouzon and Saethre-Chotzen syndromes, and its growth was disturbed in Apert, Crouzon, and Saethre-Chotzen syndromes. TP was higher at birth in Apert syndrome, but lowered faster. In Crouzon syndrome, TP was lower at birth and throughout life. A smaller clivus and larger foramen magnum were associated with a lower TP in controls (p

Hemophilia is a hemorrhagic disorder with a sex-linked inherited pattern, characterized by an inability to amplify coagulation due to a deficiency in coagulation factor VIII (hemophilia A or classic) or factor IX (hemophilia B). Sequencing of the genes involved in hemophilia has provided a description and record of the main mutations, as well as a correlation with the various degrees of severity. Hemorrhagic manifestations are related to levels of circulating factor, mainly affecting the musculoskeletal system and specifically the large joints (knees, ankles, and elbows). This document is a review and consensus of the main genetic aspects of hemophilia, from the inheritance pattern to the concept of women carriers, physiopathology and classification of the disorder, the basic and confirmation studies when hemophilia is suspected, the various treatment regimens based on infusion of the deficient coagulation factor as well as innovative factor-free therapies and recommendations for the management of complications associated with treatment (development of inhibitors and/or transfusion-transmitted infections), or secondary to articular hemorrhagic events (hemophilic arthropathy). Finally, relevant reviews of clinical and treatment aspects of hemorrhagic pathology characterized by acquired deficiency of FVIII secondary to neutralized antibodies named acquired hemophilia.

BackgroundAtaxia-telangiectasia (A-T) is an autosomal recessive disorder with high clinical heterogeneity. A-T may present in complicated variable forms, including classic A-T and milder form of AT. Contrary to the classic A-T, the milder form does not present the cardinal features of A-T such as ataxia and telangiectasia. A few ATM mutations have been reported in variant A-T cases manifesting isolated generalized or segmental dystonia without any signs of classical A-T.MethodsAn A-T pedigree with predominant dystonia was collected. Genetic testing was performed by targeted panel of genes involved in movement disorders. The candidate variants were further confirmed by Sanger sequencing. We then reviewed previously published literatures of genetically confirmed A-T cases with predominant dystonia and summarized the clinical characteristics of dystonia-dominant A-T.ResultsTwo novel ATM mutations, p.I2683T and p.S2860P, were identified in the family. The proband presented isolated segmental dystonia without any signs of ataxia and telangiectasias. We reviewed the literatures and found that the patients with dystonia-dominant A-T tend to have a later-onset and slower progression of the disease.ConclusionTo our knowledge, this is the first report of A-T patient with predominant dystonia in China. Dystonia may appear as one of the predominant manifestations or initial symptom of A-T. Early ATM genetic testing should be considered for those patients with predominant dystonia, despite without accompanying ataxia or telangiectasia.

Gorham-Stout disease (GSD) is a rare disorder characterised by massive painless osteolysis due to lymphangiomatous tissue progression. GSD’s pathogenesis is still unclear, but osteoclasts' activation may play a role in its pathogenesis. There are multiple complications associated with GSD. One of the most severe and life-threatening complications is a chylothorax. Herein we discuss a case of a patient with a history of GSD who presented to the hospital with progressive dyspnoea secondary to a large left-sided pleural effusion, which was later confirmed to be a chylothorax. We will further discuss the current literature and treatment of chylothorax associated with GSD.

We present a case of an extreme preterm infant (Baby X) born at 24-week gestation. The echocardiogram showed evidence of hypertrophic cardiomyopathy (HCM) and a patent ductus arteriosus (PDA). There are a number of well-known causes of neonatal HCM including genetic, metabolic and endocrine. PDA is commonly present in preterm infants, and this can contribute to cardiac remodelling and result in cardiac changes mimicking HCM. Furthermore, medications such as steroids can also cause HCM through various mechanisms. A careful consideration of all the different aetiologies for HCM is important for appropriate management of such cases. This report examines the evidence in the literature for the above differential diagnoses and highlights the challenges in diagnosing the underlying cause of HCM in a preterm infant.

STUDY OBJECTIVES: Excessive daytime sleepiness is common in Prader-Willi syndrome (PWS), with prevalence ranging from 52% to 100%. The goal of this study was to establish the content validity (ie, evidence that an instrument measures an intended concept of interest) of the parent/caregiver version of the Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD), a measure of daytime sleepiness, in PWS. METHODS: Qualitative, dyadic semistructured video interviews were conducted with 18 caregivers and their children with PWS from April to June 2020. Concept elicitation and cognitive interview techniques were implemented. Thematic analyses allowed for examination of themes and data patterns. RESULTS: All caregivers (mean age 49 years) were mothers of individuals with PWS who experienced troublesome daytime sleepiness (mean age 14 years). The most prevalent observable signs/symptoms of daytime sleepiness were sleepy/sleepiness (n = 17; 94.4%), tired/tiredness (n = 16; 88.9%), exhaustion/exhausted (n = 5; 27.8%), anxious/stressed (n = 5; 27.8%), irritable/frustrated (n = 5; 27.8%), having tantrums/outbursts (n = 5; 27.8%), and lethargy (n = 4; 22.2%). Daytime sleepiness impacted various aspects of health including mental, emotional, physical, and social well-being. When caregivers were asked about the activities associated with daytime sleepiness, all salient concepts elicited mapped to the ESS-CHAD; saturation was met after the first 4 interviews. Only 2 concepts, after physical exertion and while inactive/bored, did not map. Caregiver statements indicated that these concepts, although related to daytime activities, were atypical of daily routines. The ESS-CHAD was well understood and relevant to caregivers. CONCLUSIONS: This study supports the content validity of the ESS-CHAD and its appropriateness for evaluating treatment efficacy of daytime sleepiness in PWS.

The lecture deals with the questions of evaluating auscultation pattern of the cardiac murmurs in children. The classification of cardiac murmurs in children, mechanisms of the onset of organic and functional murmurs were analyzed. In particular, their differentiation was described by such indicators as the phase of occurrence, the epicenter of murmur, intensity, tone, irradiation, dependence on the respiratory phase, on the position of a child, on physical exertion and others. The attention is focused on the physician’s approach in detecting various cardiac murmurs in children.
