Ovarian hyperthecosis in adolescent females: two case reports and a review of the literature.

OBJECTIVES: Ovarian hyperthecosis (OHT) is a rare cause of severe hyperandrogenism in the adolescent age group. We describe two case reports, and present an approach to management in this age group based on a review of the literature. CASE PRESENTATION: Patient A presented at age 13 years with a 2 year history of androphonia and hirsuitism. Her testosterone level was elevated at 8.3 nmol/L, and there was marked enlargement of her ovaries bilaterally. There were no focal adrenal or ovarian lesions identified on imaging. She was treated with a gonadotropin releasing hormone (GnRH) agonist and spironolactone with biochemical and clinical improvement. Patient B presented at age 14 years with secondary amenorrhoea, and a 2 year history of androphonia, hirsutism and androgenetic alopecia. Her testosterone level was 12 nmol/L, and a pelvic ultrasound revealed numerous follicles in each ovary which were otherwise normal in size. She was managed with GnRH agonist initially, and now continues on a combined oral contraceptive pill. CONCLUSIONS: Ovarian hyperthecosis needs to be considered in pre-menopausal women presenting with severe hyperandrogenism, after exclusion of androgen-producing adrenal and ovarian tumours. The principles of management in this age group are gonadotropin suppression and hormone replacement.

Fertility outcomes in male adults with congenital hypogonadotropic hypogonadism treated during puberty with human chorionic gonadotropin and recombinant follicle stimulating hormone.

AIM: Hormone replacement therapy with testosterone for pubertal induction in boys with congenital hypogonadotropic hypogonadism (CHH) achieves virilization but not spermatogenesis. By contrast, human chorionic gonadotropin (hCG) and recombinant follicle stimulating hormone (rFSH) provides both virilization and spermatogenesis. Fertility outcomes of boys treated with recombinant therapy during adolescence have been infrequently described. We report fertility induction and pregnancy outcomes in CHH patients treated with recombinant gonadotropins during puberty. METHODS: Data of six subjects with CHH (n = 3 Kallmann syndrome & n = 3 Isolated hypogonadotropic hypogonadism) treated with hCG and FSH for pubertal induction were reviewed. Of these, five underwent subsequent fertility induction while one desired fertility at the end of pubertal induction. RESULTS: Partners of all subjects achieved pregnancies using hCG and rFSH, all with full term live births. All infants were clinically normal. CONCLUSION: This study provides early evidence of proof of concept of use of gonadotropin induction of puberty being beneficial in subsequent fertility outcome.

Prevalence of type 2 diabetes risk factors, including overweight and obesity, among youth attending hospital-based paediatric care in Western Melbourne.

AIM: To determine the prevalence of risk factors for type 2 diabetes in overweight and obese adolescents attending hospital-based paediatric care in Western Melbourne. METHODS: One hundred overweight and obese adolescents (aged 10-17 years) who attended an outpatient clinic at Sunshine Hospital between May 2019 and May 2020 were randomly selected following a retrospective chart review of 10-17 years old for whom a height and weight had been documented. Additional risk factors for type 2 diabetes were ascertained via structured telephone interview. Data were analysed to determine the overall prevalence of risk factors for type 2 diabetes, and to evaluate for associations between each parameter with body mass index and the number of risk factors. RESULTS: Of the 487 adolescents who had height and weight data recorded, 45% were overweight or obese. 77% of those who were interviewed had an additional risk factor for type 2 diabetes. No association between the number of risk factors and body mass index standard deviation score was found. Additionally, there was no association between the number of risk factors for type 2 diabetes and either family history of type 2 diabetes or ethnicity. CONCLUSIONS: This paediatric subpopulation had a high rate of risk factors for type 2 diabetes in addition to overweight and obesity, and are at risk of premature mortality and chronic morbidity should they develop type 2 diabetes.

Parechovirus infection as a cause of necrotising enterocolitis in a premature neonate.

Parechovirus is becoming increasingly recognised as a cause of morbidity in the neonatal population. It is widely known to cause sepsis, encephalitis and myocarditis. We report a case of parechovirus as a possible cause of necrotising enterocolitis in a premature neonate. The infant, who was born at 28 weeks' gestation, deteriorated at 1 month of life with fever and abdominal distension and had evidence of intramural bowel gas on imaging. Parechovirus was subsequently isolated from naso-oropharyngeal and rectal swabs, and he was managed medically with antibiotics and cessation of enteral feeds.

A prospective quality improvement study in the emergency department targeting paediatric sepsis.

OBJECTIVE: Quality improvement sepsis initiatives in the paediatric emergency department have been associated with improved processes, but an unclear effect on patient outcome. We aimed to evaluate and improve emergency department sepsis processes and track subsequent changes in patient outcome. STUDY DESIGN: A prospective observational cohort study in the emergency department of The Royal Children's Hospital, Melbourne. Participants were children aged 0-18 years of age meeting predefined criteria for the diagnosis of sepsis. The following shortcomings in management were identified and targeted in a sepsis intervention: administration of antibiotics and blood sampling for a venous gas at the time of intravenous cannulation, and rapid administration of all fluid resuscitation therapy. The primary outcome measure was hospital length of stay. RESULTS: 102 patients were enrolled pre-intervention, 113 post-intervention. Median time from intravenous cannula insertion to antibiotic administration decreased from 55 min (IQR 27-90 min) pre-intervention to 19 min (IQR 10-32 min) post-intervention (p≤0.01). Venous blood gas at time of first intravenous cannula insertion was performed in 60% of patients pre-intervention vs 79% post-intervention (p≤0.01). Fluids were administered using manual push-pull or pressure-bag methods in 31% of patients pre-intervention and 84% of patients post-intervention (p≤0.01). Median hospital length of stay decreased from 96 h (IQR 64-198 h) pre-intervention to 80 h (IQR 53-167 h) post-intervention (p=0.02). This effect persisted when corrected for unequally distributed confounders between pre-intervention and post-intervention groups (uncorrected HR: 1.36, 95% CI 1.04 to 1.80, p=0.02; corrected HR: 1.34, 95% CI 1.01 to 1.80, p=0.04). CONCLUSIONS: Use of quality improvement methodologies to improve the management of paediatric sepsis in the emergency department was associated with a reduction in hospital length of stay.
