ABSTRACT: Background: Acanthosis nigricans (AN) is a common finding often associated with hyperinsulinemia and childhood obesity. There has been a lack of studies evaluating the association of AN with underlying cardio-metabolic risk factors in children and adolescents. Our objective was to study the association between AN and cardio-metabolic risk factors in children with overweight/obesity. Methods: This cross-sectional study included school-going children (6–16 years of age) with overweight/obesity. Physical examination, anthropometry, and blood pressure (BP) data were collected. Fasting blood samples were collected to measure insulin, glucose, homeostasis model assessment index (HOMAIR), and lipid profile. Results: Of 1930 children screened, 545 had overweight/obesity, and were included. Boys to girls ratio was 1.27. AN was present in 46.4% of children. Children with AN had higher body mass index [BMI] (P < 0.01), waist circumference [WC] (P < 0.01), systolic (P = 0.03), and diastolic BP (P = 0.02), hyperglycemia (P = 0.02), hyperinsulinemia (P < 0.01), and a higher HOMA-IR (P < 0.01) compared to those without AN. HDL level was lower in children with AN. Conclusions: Children with overweight/obesity who have AN have significant elevations of BP, insulin level, and HOMA-IR. AN is a clinical marker that seems to be associated with cardio-metabolic risk factors in children with overweight/obesity in the given study population. [ABSTRACT FROM AUTHOR]

We present a one-year old, developmentally normal toddler from a non Agarwal community, who presented to us with only a large head. The examination findings were unremarkable except a large head circumference. Neuroimaging confirmed the diagnosis of megalencephalic leukoencephalopathy (MLC). Although developmental delay and seizures are common manifestations in MLC, we want to highlight the fact that many children like ours may have no neurological manifestations at all which makes it necessary to do neuroimaging to establish the diagnosis and offer genetic testing for confirmation of the same.

Background: Over-weight/obesity is a new global pandemic affecting children with prevalence up to 36%. It is responsible for metabolic syndrome and its future complications in children; however, its effect on lung functions in children is not well studied., Aim: To compare lung function tests [forced expiratory volume in the first second (FEV1), FEV1/forced vital capacity (FVC), FVC, and % predicted] of children with over-weight/obesity to that of normal children., Method: it is a hospital-based cross-sectional study. Children of 6-14 years of age with over-weight [body mass index (BMI) >85 th centile] and obesity (BMI >95 th centile) attending the pediatrics outpatient department (OPD) were included. Age-matched children attending the OPD during the study period were selected as controls. Demographic and anthropometric details were collected, and pulmonary function tests were carried out in included children., Results: A total of 103 children were included (over-weight/obese = 56, control = 47). The percent predicted (%) FEV1 (86.23 ± 12.84 vs 91.77 ± 8.68) and FVC (81.93 ± 12.12 vs 88.62 ± 10.87) were significantly lower in the obese/over-weight group as compared to control group. A signification negative correlation was found between FEV1 (%) and FVC (%) and that of BMI and waist-hip ratio (WHR)., Conclusions: Pulmonary functions (FEV1, FVC) are found to be negatively correlated with BMI and WHR., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Family Medicine and Primary Care.)
