Inappropriate supplementation of Vitamin D can result in toxicity: a crosssectional study of paediatrics population.

OBJECTIVE: To evaluate children with suspected or definite hypervitaminosis D with respect to prevalence, clinical manifestations and pharmacological aspects. METHODS: The retrospective cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, and comprised medical records from January 1 to December 31, 2018, of children aged <18 years with 25-hydroxyvitamin D levels >50ng/ml. Clinical and pharmacological data was retrieved. Data was analysed using SPSS 23. RESULTS: Of the 118,149 subjects visiting the clinical laboratory during the study period, children tested for serum 25-hydroxyvitamin D levels were 16,316(13.8%) who had a median age of 9.78 years (interquartile range: 10.2 years). Children who registered for consultation were 2720(16.6%), and, out of them, 602(22%) had serum 25-hydroxyvitamin D >50ng/ml. The median 25-hydroxyvitamin D levels and age were 70.1ng/ml (interquartile range: 100ng/ml) and 3.1 years (interquartile range: 17.93 years), respectively, and 345(57.3%) of them were boys. Children supplemented with vitamin D were 197(33.1%) and 193(97.9%) of them were prescribed by physicians. Mega-doses were taken by 68(34.17%), while the remaining had used various combinations in syrup or tablet forms. Commonly prescribed mega-doses were 600,000IU 30((44.1%) and 200,000IU 31(45.5%) injections of vitamin D. The primary indications were pains/aches in 51(25.8%) cases, developmental delay 50(25.3%), and vitamin D deficiency 49(24.8%). The main symptoms of hypervitaminosis D or toxicity were abdominal pain 27(13.7%) and constipation 31(15.7%). CONCLUSIONS: Children should be given vitamin D supplements with caution as prolonged supplementation and repeated mega-doses can result in toxicity which may cause serious consequences.

Referral pattern and outcomes of neonates from secondary care setting of Aga Khan University Hospital to tertiary care centers in Pakistan.

OBJECTIVE: To determine the reasons of neonatal referrals from secondary-care to tertiary-care setting, and to assess neonatal outcomes for the referred cases. METHODS: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised data from July 2015 to June 2019 Related to all neonates born after 32 weeks of gestation at the satellite secondary-care centres in Kharadar, Garden and Karimabad who had been referred to the main tertiary care hospital. The reason for referral, need of mechanical ventilation, referral place and neonatal outcome were noted. Data was analysed using SPSS 22. RESULTS: Of the 348 cases, 211(60.6%) were boys. The overall mean gestational age was 36.42±2.61 weeks and the mean birth weight was 2.54±0.67 kg. The outcome was neonatal mortality in 42(12%) cases. Of the remaining 306(88%) cases, 284(92.81%) were discharged from the hospital and 22(7.18%) left against medical advice. Overall, mechanical ventilation was needed in 63(18.1%) patients. There was a significant association of mechanical ventilation with low Appearance, Pulse, Grimace, Activity, and Respiration score at 1 and 5 minutes (p<0.001), shorter duration of stay (p=0.007), and aggressive resuscitation requirement at birth (p<0.001). CONCLUSIONS: The most common reasons for referral of newborns to tertiary care hospital were respiratory diseases requiring respiratory support and surgical intervention.

A Neonate with Upper GI Bleeding.

Bleeding in the newborn is often a serious problem because of cardiovascular effects associated with a loss of blood and/or the damaging effects of bleeding on neonatal tissues, especially the brain. Gastric polyps are described as abnormal lesions that originate in the gastric epithelium or submucosa and protrude into the stomach lumen. Clinical presentation of gastric polyps in children varies widely, from incidental endoscopic finding to massive gastrointestinal bleeding. However, acute gastrointestinal bleeding in association with hyperplastic gastric polyps has been reported very rarely. We report a case of unusual upper gastrointestinal bleeding in newborn baby on 2nd day of life, secondary to gastric polyp, which was diagnosed and resected through endoscopy.

Harlequin Colour Change.

Harlequin colour change (HCC) is a rare, benign and transient colour change presenting in normal healthy neonates in initial days of life and resolves spontaneously. It is thought to be due to hypothalamic immaturity, leading to capillary bed dysregulation. Gravity might also play a role, as this is apparent on the dependent side. It is important for physicians to recognize this phenomenon so that they do not order any irrelevant investigations. Here, we present a case of a healthy neonate who had HCC, which was unilateral, well demarcated erythema, with patchy pallor. Baby was vitally stable at that time. This colour change was observed twice and each time resolved within 20 minutes of its appearance and was not observed again to date (after 20 days). Baby was discharged in a stable condition after 48 hours of life.
