Aim: This study examines trends in paracetamol overdoses among Danish adolescents during and following the COVID-19 pandemic., Methods: A retrospective observational study was conducted using data from the national databases, covering all paediatric departments in Denmark from January 2016 to December 2023. Patients between 10 and 19 years of age diagnosed with paracetamol overdose were stratified by sex, age and number of hospital admissions. As the dataset covers the entire population, observed values reflect true parameters. A one-sample t-test compared post-COVID-19 values to the pre-COVID-19 mean., Results: A total of 4.448 patients accounted for 5.794 hospital admissions due to paracetamol overdoses, with a majority being girls. During the second year of the pandemic (2021), a rise in overdose cases (26.5%) and hospital admissions (30.3%) was observed, especially among girls. The average number of admissions per patient increased, indicating repeated self-harm attempts. Cases of severe overdoses leading to acute liver failure increased at Rigshospitalet. These trends reversed post-pandemic., Conclusion: The findings suggest an association between pandemic-related isolation and an increase in adolescent paracetamol overdoses. While rates began to normalise after restrictions were lifted, further research is needed to assess the long-term mental health impact of such restrictions., (© 2025 The Author(s).

Introduction: To assess the effect of long-term isolation on the mental state of Danish youth. This study aimed to investigate trends in paracetamol overdoses among people under 18 years of age in Denmark during Covid-19 restrictions as an indicator of mental health., Methods: All patients under the age of 18 years presenting with paracetamol overdose at one of the 18 paediatric departments in Denmark from 2016 to 2021 were included. They were identified in all Danish hospital databases using specific diagnostic codes., Results: From 2016 to 2021, a total of 3,217 people under 18 years of age were admitted for paracetamol overdose. Among these, 86% (n = 2,755) were girls and 14% (n = 462) were boys. During 2020, a slight (7%) decrease in admissions was observed among both boys and girls compared with the preceding four-year mean value. In 2021, the number of overdoses among girls exceeded by 35% the former all-time high from 2016. Furthermore, the number of overdoses among girls exceeded the pre-four-year period mean value by 43%. Among boys, an 8% increase was seen from the highest ever previous value recorded in 2019 and a 23% increase compared with the previous four-year mean value., Conclusions: During the first year of restrictions, a slight decrease in paracetamol overdoses was observed, possibly associated with limited accessibility. The second year showed a considerable increase in paracetamol overdoses, which may imply an affected mental state among youth during the prolonged lockdown restrictions as seen in previous epidemics. Therefore, further studies are warranted to develop a pandemic preparedness plan to protect general mental health., Funding: None., Trial Registration: Not relevant., (Published under Open Access CC-BY-NC-BD 4.0. https://creativecommons.org/licenses/by-nc-nd/4.0/.)

Context: Most Turner syndrome (TS) girls need exogenous estrogen treatment to induce puberty and normal uterine growth. After puberty, the optimal estrogen treatment protocol has not been determined., Objective: To compare 2 doses of oral 17ß-estradiol on uterine size., Design: A double-blind, 5-year randomized controlled clinical trial., Setting: Ambulatory care., Participants: Twenty young TS women (19.2 ± 2.5 years, range 16.0-24.9) participated. Sixteen patients completed the study. No patients withdrew due to adverse effects., Intervention: The lower dose (LD) group took 2 mg 17ß-estradiol/d orally and placebo. The higher dose (HD) group took 4 mg 17ß-estradiol/d orally., Main Outcome Measure(s): Uterine volume evaluated by transabdominal ultrasound yearly., Results: Uterine size increased significantly more in the HD group compared with the LD group (P = 0.038), with a gain in uterine volume within the first 3 years of treatment of 19.6 mL (95% confidence interval [CI] = 4.0-19.0) in the HD group compared with 11.5 mL (95% CI = 11.2-27.9) in the LD group. The difference in 3-year gain was 8.1 mL (95% CI = 0.7-15.9). At the last visit, there were no significant differences in uterine volume between the groups., Conclusion: HD oral 17ß-estradiol induces a steeper increase in uterine volume within the first years of treatment compared with the LD. However, the uterine growth potential seems to be the same in most young TS women making the duration of treatment equally significant as estrogen dose, although a few TS women did not experience sufficient uterine growth on 2 mg of estradiol., Clinicaltrials.gov: NCT00134745Abbreviations: BMI, body mass index; BSA, body surface area; DHEAS, dihydroepiandrosteronesulfate; HD, higher dose; HRT, hormone replacement therapy; LD, lower dose; TS, Turner syndrome; US, ultrasound., (© Endocrine Society 2019.

Background: Pain management in hospitalized children is often inadequate. The prevalence and main sources of pain in Danish university hospitals is unknown., Methods: This prospective mixed-method cross-sectional survey took place at four university hospitals in Denmark. We enrolled 570 pediatric patients who we asked to report their pain experience and its management during the previous 24 hours. For patients identified as having moderate to severe pain, patient characteristics and analgesia regimes were reviewed., Results: Two hundred and thirteen children (37%) responded that they had experienced pain in the previous 24 hours. One hundred and thirty four (24%) indicated moderate to severe pain and 43% would have preferred an intervention to alleviate the pain. In children hospitalized for more than 24 hours, the prevalence of moderate/severe pain was significantly higher compared to children admitted the same day. The single most common painful procedure named by the children was needle procedures, such as blood draw and intravenous cannulation., Conclusion: This study reveals high pain prevalence in children across all age groups admitted to four Danish university hospitals. The majority of children in moderate to severe pain did not have a documented pain assessment, and evidence-based pharmacological and/or integrative ('non-pharmacological') measures were not systematically administered to prevent or treat pain. Thus, practice changes are needed., (© 2016 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.)

Objective: To study the effect of growth hormone (GH) treatment on ovarian and uterine morphology and function in short, prepubertal small-for-gestational-age (SGA) girls., Design: A multinational, randomized controlled trial on safety and efficacy of GH therapy in short, prepubertal children born SGA., Setting: Not applicable., Patient(s): A subgroup of 18 Danish girls born SGA included in North European SGA Study (NESGAS)., Intervention(s): One year of GH treatment (67 μg/kg/day) followed by 2 years of randomized GH treatment (67 μg/kg/day, 35 μg/kg/day, or IGF-I titrated)., Main Outcome Measure(s): Data on anthropometrics, reproductive hormones, and ultrasonographic examination of the internal genitalia were collected during 36 months of GH treatment., Result(s): Uterine and ovarian volume increased significantly during 3 years of treatment (64% and 110%, respectively) but remained low within normal reference ranges. Ovarian follicles became visible in 58% after 1 year compared with 28% before GH therapy. Anti-Müllerian hormone increased significantly during the 3 years of GH therapy but remained within the normal range. Precocious puberty was observed in one girl; another girl developed multicystic ovaries., Conclusion(s): GH treatment was associated with statistically significant growth of the internal genitalia, but remained within the normal range. As altered pubertal development and ovarian morphology were found in 2 of 18 girls, monitoring of puberty and ovarian function during GH therapy in SGA girls is prudent. Altogether, the findings are reassuring. However, long-term effects of GH treatment on adult reproductive function remain unknown., Clinical Trial Registration Number: EudraCT 2005-001507-19., (Copyright © 2014 American Society for Reproductive Medicine.

A six-year-old boy presented with fever, neck pain, and ear pain. Within days, the motility of his neck limited, his temperature rose, and blood samples showed signs of infection. On suspicion of cervical spondylodiscitis, a bone scintigraphy was performed, but gave negative results. A magnetic resonance imaging of the neck area showed results, which led to the diagnosis of a retropharyngeal abscess. This case is a reminder that retropharyngeal abscess poses a diagnostic challenge for the physician, and that the prognosis is potentially serious.

Objective: To determine uterine and ovarian size in Turner syndrome (TS) and to compare uterine and ovarian size evaluated by transabdominal ultrasound (US) and magnetic resonance imaging (MRI) in girls with TS and two groups of controls., Design: A cross-sectional study., Patients: Forty-one girls with TS (17·0 ± 3·3 years, range 11·2-24·9 years), 50 healthy age-matched controls (16·9 ± 3·2 years, range 12·5-25·0 years) and 107 Tanner-stage-matched controls (15·0 ± 3·2 years, range 10·1-24·2)., Measurements: Uterine and ovarian volume by US and MRI., Results: Ovaries were detected in 37% in TS by US and in 55% in TS by MRI (P = 0·1). Total ovarian volume was lower in TS compared to both groups of controls (TS vs C-US: median 1·1 ml (range 0·1-29·3) vs 11·52 ml (1·9-77·9), P = 0·001, TS vs C-MRI: 1·0 ml (0·1-34·2) vs 13·2 ml (2·4-30·1), P < 0·0005). Mean difference in total ovarian volume measured by MRI and US in patients with TS was 2·3 ± 3·8 ml (P = 0·01). Mean uterine volume by MRI was lower in TS compared to controls (29·5 ± 25·1 vs 54·3 ± 23·3 ml, P < 0·0005). Uterine volume by US was lower in TS at Tanner stage B5 compared to controls (TS vs C: 33·6 ± 18·2 vs 50·2 ± 18·0 ml, P = 0·007)., Conclusions: A larger ovarian volume was detected by MRI in TS compared to US. This finding is important with the advancements of performing ovarian biopsies for cryopreservation and later reimplantation. Mean uterine volumes by MRI and US in fully matured TS were lower compared to controls despite appropriate hormonal replacement therapy in TS., (© 2011 Blackwell Publishing Ltd.)

Fibroblast growth factor receptor 3 (FGFR3) gene mutations in the germline are well-known causes of skeletal syndromes. Somatic FGFR3 mutations have been found in malignant neoplasms and more recently in several cutaneous elements. We present a 14-year-old girl with mild hypochondroplasia who developed acanthosis nigricans. The report of a K650Q mutation in the FGFR3 gene in a similar case prompted us to conduct a point mutation analysis. The K650Q mutation was confirmed, but in contrast to the previous case, we additionally report findings of hyperinsulinemia. In the recent literature, an increasing number of different cutaneous elements have been found to harbor mutations of FGFR3, suggesting that FGFR3 plays a role in the pathogenesis of these elements. We review the present literature, describing studies in which FGFR3 mutations have been investigated in skin lesions: primarily seborrheic keratoses and epidermal nevi, but also other benign skin tumors and a single case of a squamous cell carcinoma. In addition, an overview of the FGFR3 point mutations in relation to each cutaneous element is given. Based on the current knowledge, it seems likely that these cutaneous lesions have a common genetic background. Our case shows that FGFR3 mutation analysis should be considered in case of the coexistence of acanthosis nigricans and a skeletal dysplasia. Testing for hyperinsulinemia is essential, also if a gene mutation is confirmed., (Copyright (c) 2010 S. Karger AG, Basel.)

Individuals with Turner syndrome (TS) are prone to develop autoimmune conditions such as coeliac disease (CD), thyroiditis and type 1 diabetes (T1DM). The objective of the present study was to examine TS of various karyotypes for autoantibodies and corresponding diseases. This was investigated in a prospective cross-sectional study of Danish TS patients (n = 107, median age 36.7 years, range: 6-60 years). A medical history was recorded and a blood sample was analysed for autoantibodies against gliadin, transglutaminase, adrenal cortex, intrinsic factor, anti-thyroid peroxidase (anti-TPO) and glutamic-acid-decarboxylase 65 (GAD-65). Autoantibodies were present in 58% (n = 61) of all patients, whereof 18% (11) had autoantibodies targeting more than one organ. Patients with autoantibodies were significantly older than those without (P = 0.001). Anti-TPO was present in 45% (48) of patients, of whom 33% (16) were hypothyroid. Overall, 18% (19) presented with CD autoantibodies, of whom 26% (five) had CD. Anti-TPO and CD autoantibodies co-existed in 9% (10). Immunoglobulin A deficiency was found in 3% (three) of patients, who all had CD autoantibodies without disease. Among four patients with anti-GAD-65 none had T1DM, but two were classified as having T2DM. One patient had adrenocortical autoantibodies but not adrenal failure. Autoantibodies against intrinsic factor were absent. Anti-GAD-65 was increased in isochromosomal karyotypes (3/23 versus 1/84, P = 0.008) with no other association found between autoantibodies and karyotype. In conclusion, TS girls and women face a high prevalence of autoimmunity and associated disease with a preponderance towards hypothyroidism and CD. Thus, health care providers dealing with this patient group should be observant and test liberally for these conditions even before clinical symptoms emerge.

Gitelman's syndrome is a rare autosomal recessive syndrome presenting with hypocalciuria, hypomagnesiemia and hypokalemic metabolic alkalosis. This case reports a patient admitted with generalized seizures with the above-mentioned biochemical abnormalities, thus representing a rare onset of Gitelman's syndrome which - to our knowledge - has not been described previously. The patient had a homozygote deletion of the CLC-KB gene, CLCNKB. The case was successfully treated by correcting hypokalemia and hypomagnesiemia with supplemental potassium and magnesium.
