Youth-onset metabolic diseases, including obesity and type 1 and type 2 diabetes, and their associated cardiometabolic complications represent a major global health challenge. The incidence and prevalence of these conditions vary across regions, with rising trends and a heavier burden observed in middle- and low-income countries. Diet, physical activity and lifestyle choices are key factors in the development and progression of metabolic diseases during childhood and adolescence, along with additional risk factors such as genetic predisposition, ancestry, ethnicity, lifetime events (i.e. puberty) and other environmental factors. Disparities in access to healthcare, diagnostic and management capabilities and treatment options across the world affect outcomes, contributing to high morbidity and mortality rates, particularly in low-resource settings. Compared with onset during adulthood, an early diagnosis of metabolic diseases is associated with a higher risk and severity of complications, including adverse vascular outcomes and premature mortality. Although clinical signs of cardiovascular complications typically appear in adulthood, they are the result of a long, subclinical disease process that can begin in childhood and adolescence. This underscores the need for early prevention strategies and effective treatments to reduce the short- and long-term health impacts of these conditions. Addressing the rising prevalence of metabolic diseases, especially among vulnerable populations, requires comprehensive, culturally tailored actions that consider the available resources in diverse settings. Graphical Abstract

Context: Prolonged hypothyroidism in children commonly causes short stature with delayed bone maturation, and delayed puberty. However, a paradoxical occurrence of peripheral precocious puberty and pituitary enlargement in chronically untreated juvenile hypothyroidism was first reported by Van Wyk and Grumbach in 1960. Objective: To create increased awareness and a better understanding of this clinical entity among emergency room physicians, pediatricians, surgeons, gynecologists and oncologists. Methods: Case records of children diagnosed with Van Wyk–Grumbach syndrome (VWGS) were analyzed retrospectively. Results: Twenty-six girls and 4 boys were identified (2005-2020). All had profound primary hypothyroidism (total thyroxine [T4]: 2.5-33.5 nmol/L, thyrotropin: > 75-3744 μIU/mL). Hypothyroidism was not the referral diagnosis in any of the girls. Among them, 17 were referred for precocious puberty, 5 with a diagnosis of pituitary tumor on magnetic resonance imaging, and others for acute surgical abdomen in 7 girls (painful abdominal mass—2, ovarian tumor—2, ovarian torsion—2, ruptured ovarian cyst—1), acute myelopathy in 1, and menorrhagia with headache in another. All girls were successfully managed with levothyroxine replacement alone, except for the 2 with ovarian torsion, who required surgery. Menstruation ceased promptly with T4 therapy in all girls, occurring at an age-appropriate later date. All boys had testicular enlargement at presentation that regressed partially after T4 treatment. Catch-up growth was remarkable during the first treatment year, but the final height was compromised in all. Conclusion: Increased awareness of varied presentations of VWGS is vital among pediatricians to facilitate early diagnosis and targeted investigations, and to help in the initiation of the simple yet highly rewarding T4 replacement therapy to avoid all possible complications.

Objectives: Children with type 1 diabetes (T1D) need a supportive, non-stigmatizing school environment for self-care activities such as checking blood glucose (BG) and taking pre-meal insulin. Data about T1D self-care in schools in developing countries are scarce. We looked at diabetes self-care activities at school, and attitudes of school staff toward diabetes care. Material and Methods: We interviewed, over an 8-week period, consecutive patient-parent dyads attending T1D clinics in North (Delhi, Gurgaon, and Kanpur), West (Aurangabad), and South (Hyderabad) India. Results: We received responses from 397 patients, 51% of boys. Mean age was 11.7 years (SD: 3.7), mean age at diagnosis 7.2 years (SD: 3.7), and mean diabetes duration 4.5 years (SD: 3.5). A majority (69.8%) were attending private (fee paying) schools (PS) and the rest were studying at government (subsidized/free) schools (GS). More than half of the parents had high educational status: graduate or more (mothers: 52.1%, fathers: 56.9%). Parents visited school daily in 17.1%, significantly more if they had high educational status and if the child was <6 years. Less than half (47.4%) were administering a pre-meal insulin bolus at school (self-injection: 33%, by parent: 12.9%, and by staff: 1.5%); only 24.4% were checking BG regularly (< once per week) at school. The odds of performing diabetes self-care activities at school were significantly higher in children attending PS compared to GS (OR: 3.17, 95% CI: 1.99–5.03 for taking insulin, OR: 3.24, 95% CI: 1.75–5.98 for regular BG checking). The odds of taking insulin at school were also higher with higher parental education (OR: 2.81, 95% CI: 1.87–4.24 for mother’s education, OR: 3.02, 95% CI: 1.99–4.57 for father’s). Testing and injecting we done in classroom (26.2%); medical room (16.1%), staffroom (7.8%), or toilet (2.5%). School insisted on secrecy in 12.6%, excluded children with T1D from sports/excursions in 17.9%, refused permission for injecting in 4.3%, for testing 15.9%, and for pre-activity snack 7.6%. This non-supportive behavior was equal in PS and GS. PS had slightly better care infrastructure such as availability of glucometer (29.6% vs. 3.3%), sick room (21.7% vs. 0.3%), and dedicated nurse (9.7% vs. none). Conclusion: Half of our children were able to manage T1D self-care in school, as schools were often supportive, whether private or government. Parental educational status was positively associated with better care. Although self-care was better in PS and they had better infrastructure, there is much scope for improvement.

Background We present the results of the pilot study of a multinational “Diabetes Know-Me” project investigating knowledge regarding diabetes of medical students. This is the first collaborative project of the ISPAD JENIOUS group. Methods Students of the final year of medical studies from six countries answered a 25-question survey regarding basic knowledge concerning diabetes (1091 surveys handed out, response rate 86%). Results Among the responders (58% female) 90% confirmed attending diabetology classes; 11% planned to specialize in diabetology. There were significant differences between countries in the median score of correct answers ranging from 10/25 to 22/25. Attending diabetes classes (20 vs. 13/25, p < 0.0001) was the strongest factor associated with improved knowledge about diabetes (other factors analyzed were: gender, familiar/personal experience of diabetes, interest to specialize in diabetology). Conclusions Basic knowledge about diabetes remains a challenge. Participating in classes concerning diabetes contributed the most to the diabetes-related knowledge among students of the final year of medical faculties.

Background: Both calcium (Ca) and phosphorus (P) are needed to prevent and treat metabolic bone disease (MBDP). However, the predominant focus of many treating neonatologists lies in supplementing P and vitamin D. In this report, we describe a VLBW infant with severe MBDP due to inadequately treated calcium deficiency and discuss the need to recognize this entity.Case details and management: A 25-week, 700 gm baby boy had chronic lung disease and necrotizing enterocolitis. He received total parenteral nutrition, budesonide, furosemide, and caffeine. With high serum alkaline phosphatase (ALP: 1,700 IU/L) and low P (2.8 mg/dl), MBDP was diagnosed at 12 weeks, started on oral phosphate, human milk fortifier, and 1,400 IU/d of vitamin D before discharge. He was readmitted 2 weeks later with decreased lower limb mobility and respiratory distress. X-rays revealed severe osteopenia and fractures of both femurs. Serum P was 4.6 mg/dl but ALP was high (1,700 IU/L), and Ca was low (6.4 mg/dl). Parathyroid hormone (PTH: 605 pg/ml) and 25-hydroxy Vitamin D (25 OHD > 200 ng/ml) were very high. We discontinued his P and vitamin D, hypocalcemia treated with IV Ca gluconate, later oral Ca citrate, and calcitriol. Phosphate was added after normalization of Ca. Over the next many weeks, X-rays and biochemistry improved.Discussion: MBDP results from both Ca and P deficiencies, especially in VLBW infants with comorbidities. P supplementation without treating underlying calcipenia can precipitate hypocalcemia and worsen osteopenia with disastrous consequences. In severe calcipenia, active vitamin D might have a role in addition to an appropriate dose of elemental calcium.
