BACKGROUND: Polycystic ovary syndrome (PCOS) treatment in adolescents currently focuses on lifestyle interventions, with pharmacological treatment options often limited to hormonal contraceptives. Several of these carry broad side-effect profiles and are not always accepted by young girls. There is growing interest in non-hormonal therapies for PCOS. We aimed to collate the evidence on the use of myoinositol or D-chiro-inositol in the improvement of PCOS symptoms in symptomatic adolescents...

OBJECTIVES: Investigate serum vitamin D (vit D) levels' relation to uterine volume in idiopathic central precocious puberty (ICPP) girls and compare findings with normal peers. METHODS: Analyzed 278 ICPP cases from January 2017 to September 2022 alongside 239 normally developing girls. Collected clinical data and lab markers and performed subgroup analysis based on vit D levels. Correlation and regression analyses were conducted. RESULTS: The ICPP group exhibited elevated uterine volume and lower serum vit D compared to controls (p<0...

OBJECTIVES: Pseudohypoparathyroidism (PHP1B) is most commonly caused by epigenetic defects resulting in loss of methylation at the GNAS locus, although deletions of STX16 leading to GNAS methylation abnormalities have been previously reported. The phenotype of this disorder is variable and can include hormonal resistances and severe infantile obesity with hyperphagia. A possible time relationship between the onset of obesity and endocrinopathies has been previously reported but remains unclear...

OBJECTIVES: To assess auxological parameters, adult height outcome and its determinants in Indian girls with idiopathic central precocious puberty (iCPP) treated with gonadotropin-releasing hormone analogues (GnRHa). METHODS: Retrospective study. Inclusion: data on girls with iCPP from initiation to stopping GnRHa (n=179). Exclusion: boys, peripheral, organic central precocity. RESULTS: Mean age of starting GnRHa: 8.2± 1.1 years, duration: 2...

Patients with congenital hypogonadism will encounter many health care professionals during their lives managing their health needs; from antenatal and infantile periods, through childhood and adolescence, into adult life and then old age. The pubertal transition from childhood to adult life raises particular challenges for diagnosis, therapy and psychological support, and patients encounter many pitfalls. Many patients with congenital hypogonadism and delayed or absent puberty are only diagnosed and treated after long diagnostic journeys, and their management across different centres and countries is not well standardised...

OBJECTIVES: Neuronal ceroid lipofuscinosis type 11 (NCL11) is a rare disease that presents with progressive cognitive decline, epilepsy, visual impairment, retinal atrophy, cerebellar ataxia and cerebellar atrophy. We present herein a case of NCL11 in a patient diagnosed with neuromotor developmental delay, epilepsy, bronchiolitis obliterans and hypothyroidism. CASE PRESENTATION: A 4-year-old male patient was admitted to our clinic with global developmental delay and a medical history that included recurrent hospitalizations for pneumonia at the age of 17 days, and in months 4, 5 and 7...

OBJECTIVES: Gonadotropin-releasing hormone (GnRHa) is the first choice for the treatment of patients with central precocious puberty (CPP). However, the effects of GnRHa on the endocrine system of CPP patients, including insulin sensitivity, lipid level, thyroid function, bone mineral density (BMD), and testosterone (T) level, are currently contradictory. Therefore, the long-term safety of GnRHa therapy remains controversial. CONTENT: A systematic literature search was performed using PubMed, Embase, Cochrane Library, and CNKI databases...

OBJECTIVES: We aimed to identify perinatal risk factors associated with hyperinsulinemic hypoglycemia in neonates. Secondary objectives included an examination of clinical and biochemical characteristics at the time of diagnosis and an exploration of the duration of diazoxide therapy. METHODS: A case-control study was conducted, involving individual chart reviews of inborn infants diagnosed with hyperinsulinemic hypoglycemia (the HH group) between 2014 and 2021...

OBJECTIVES: Abdominal pain is a common presentation in patients of diabetic ketoacidosis (DKA). However, this pain generally resolves with resolution of dehydration and acidosis. Persistence of abdominal pain even after resolution of ketosis and acidosis should warrant careful reassessment to find evidence of sepsis and concomitant abdominal pathology. CASE PRESENTATION: We report a rare case of type 1 diabetes mellitus in a 15 year old girl diagnosed 6 months ago who presented with mild DKA (pH 7...

OBJECTIVES: Newborn screening (NBS) for primary carnitine deficiency (PCD) exhibits suboptimal performance. This study proposes a strategy to enhance the efficacy of second-tier genetic screening by adjusting the cutoff value for free carnitine (C0). METHODS: Between January 2021 and December 2022, we screened 119,898 neonates for inborn metabolic disorders. Neonates with C0 levels below 12 μmol/L were randomly selected for second-tier genetic screening, employing a novel matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) assay...

Congenital hyperinsulinism (CHI) with variants in ABCC8 and KCNJ11 is highly correlated with poor responsiveness to diazoxide, a first-line medication of CHI. Currently, there is only one reported case of a patient with CHI due to double heterozygous variants of ABCC8 and KCNJ11 . Little is known about the long-term prognosis of the CHI patient with ABCC8 and KCNJ11 double heterozygous variants. Herein, we report a CHI patient with ABCC8 and KCNJ11 double heterozygous variants after 6 years of follow-up.
