Review on the screening of urine glucose for early diagnosis of type 2 diabetes mellitus in school children and adolescents with obesity in Hong Kong.

Objectives: Obesity and type 2 diabetes mellitus (T2DM) are growing health concerns. Since 2005, Student Health Service (SHS) and Hong Kong Paediatric Society formulated a protocol on urine glucose screening (UGS) for early diagnosis of T2DM in students with obesity in Hong Kong. This study reviews students with T2DM captured by this screening program and compare the data with the Hong Kong Children Diabetes Registry (HKCDR) database, to see if the UGS program facilitates early diagnosis of T2DM.

Ovarian Hyperthecosis in a 12-year-old Chinese Girl Presenting With Virilization.

All girls presenting with virilization (which signifies severe hyperandrogenism) warrant thorough investigation. Ovarian hyperthecosis (OHT) is a rare cause of virilization in premenopausal women. Here, we report the case of a previously healthy 12-year-old Chinese girl with signs of virilization at puberty.

A Baby With Complete Androgen Insensitivity Syndrome and the Fortuitous Discovery of 45,X/46,XY Mosaicism.

Disorders of sex development (DSD) are caused by defects in the complex sexual differentiation cascade, resulting in discordance among an individual's genetic, gonadal, and genital sexes. It affects one in 4,500 live births. A wide spectrum of genital phenotypes can be found depending on the underlying pathogenic mechanism and the developmental stage that is affected.

Lithium as an alternative option in thionamide-resistant Graves' disease.

Conventional treatments for Graves' disease include thionamides, radioactive iodine therapy (RAI), and thyroidectomy. Occasionally, patients may develop resistance to thionamides and may require additional treatment. We present the case of an adolescent girl with thionamide-resistant Graves' disease who was successfully treated with lithium and subsequent RAI after stabilizing her thyroid hormone levels.

Diabetic ketoacidosis in children with new-onset type 1 diabetes mellitus: demographics, risk factors and outcome: an 11 year review in Hong Kong.

Objectives: Diabetic ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes (T1D). The aim of this study is to analyze the incidence, clinical characteristics, management and outcome of children presenting with DKA in new-onset T1D from 2008 to 2018 in Hong Kong.

Methods: Data was extracted from the Hong Kong Childhood Diabetes Registry.

Incidence and clinical characteristics of pediatric-onset type 2 diabetes in Hong Kong: The Hong Kong childhood diabetes registry 2008 to 2017.

Objective: With increasing prevalence of childhood obesity worldwide, the incidence of pediatric-onset type 2 diabetes (T2D) is also increasing in many countries. We aim to analyze the time trend and incidence of T2D in children in Hong Kong from 2008 to 2017, and to characterize clinical characteristics at diagnosis.

Methods: Data were retrieved from the Hong Kong Childhood Diabetes Registry.

Increasing incidence of type 1 diabetes among Hong Kong children and adolescents: The Hong Kong Childhood Diabetes Registry 2008 to 2017.

Objective: The incidence of childhood-onset type 1 diabetes (T1D) has been reported to be rising but there is also evidence that it has been attenuated in recent years. We described the time trends and the incidence of T1D in children in Hong Kong from 2008 to 2017 and compared with the previous local registry in 1997 to 2007.

Methods: Data were extracted from the Hong Kong Childhood Diabetes Registry, which was established in 2016.

Water deprivation test in children with polyuria.

Polyuria is an uncommon clinical presentation in paediatric practice. When diabetes mellitus has been excluded by history taking and preliminary investigations and impaired renal concentrating ability is confirmed, water deprivation test (WDT) is necessary to differentiate among central diabetes insipidus (CDI), nephrogenic diabetes insipidus, or primary polydipsia. Traditionally, responsiveness to desmopressin injection is defined as urine osmolality >750 mOsm/kg.

A 12-year-old chinese girl with Cushing syndrome and virilization due to adrenocortical carcinoma.

A Chinese adolescent girl presented with secondary amenorrhea. During follow-up, she gradually developed Cushingoid features and virilization. After a series of endocrine investigations, including urinary steroid profiling, a diagnosis of adrenocortical carcinoma was made.
