Is Kawasaki disease incidence rising in Chandigarh, North India?

Objective To estimate incidence of Kawasaki disease (KD) over time among children in the city of Chandigarh, North India. Patients and methods We analysed records of all children with KD below 15 years of age at the Pediatric Allergy Immunology Unit, Advanced Pediatrics Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, from January 1994 to December 2008. Diagnosis and treatment of KD were based on American Heart Association criteria. Among these cases, children residing in Chandigarh were identified. Yearly incidence was calculated and compared from 1994 to 2008. Results During this period, 196 children were diagnosed as KD. Of these, 80 (40.8%; 48 boys, 32 girls) resided in Chandigarh. Four among these had coronary artery abnormalities (CAA) on echocardiography, while two had mitral regurgitation. Comparison of yearly data revealed increasing incidence of disease from 0.51 cases in 1994 to 4.54 cases per 100 000 children below 15 years of age in 2007. Majority (93.7%) of cases occurred in children ≤10 years of age with the highest incidence reported in the seventh year of life. Monthly distribution of disease showed two peaks with a maximum number of cases presenting in October followed by a second peak in May with a nadir in the month of February. Conclusion Increasing incidence of KD in Chandigarh could be due to increasing clinical recognition as a result of greater awareness among paediatricians in the city, or may represent an actual increase in numbers. Striking differences from KD series reported from other countries include the older median age of our patients, low rate of CAA and a different bimodal seasonality, which may be epidemiologic clues to the nature of this vasculitis.

Nutritional status and complications in children with diabetic ketoacidosis.

Objective: Diabetic ketoacidosis in children continues to be an important cause of morbidity and mortality, especially in developing economies as a result of malnutrition, a high rate of infections, and delay in seeking timely medical care. Malnutrition also increases the risk of diabetic ketoacidosis-related complications. The objective of this study was to assess the nutritional status of patients presenting with diabetic ketoacidosis and correlate it with the incidence of complications at presentation and those encountered during the course of illness. Design: Prospective study. Setting: Pediatric emergency and intensive care units, Advanced Pediatrics Centre, PGIMER, Chandigarh, India. Patients: Thirty-three children between 1 month and 12 yrs of age presenting with diabetic ketoacidosis between July 2008 and June 2009 were enrolled consecutively and assessed for nutritional status by anthropometric parameters (body weight, crown–heel length/height, mid–upper arm circumference, triceps and subscapular skin fold thicknesses), biochemical parameters (serum albumin, zinc, magnesium, vitamin A levels), and preillness dietary history (by pretested Food Frequency Questionnaire). Patients were classified as malnourished or normally nourished based on the weight for age criteria matched for Indian standards. The incidence of complications (electrolyte imbalances, hypoglycemia, sepsis, cerebral edema, etc.) and outcome in terms of survival or death in both the groups were compared with Student’s t-test for parametric data, Mann-Whitney U test for nonparametric data, and chi-square test for categorical variables. Interventions: None. Measurements and Main Results: Anthropometric assessment showed that 11 of 33 (33.3%) were malnourished. Preillness dietary history revealed that 16 (48.5%) were calorie- and protein-deficient (known diabetic n = 7; new onset n = 9), whereas 11 (33.3%) were only calorie-deficient (known diabetic n = 2). Hypoalbuminemia was seen in 21 (63.6%), hypovitaminosis A in eight (24.2%), and low zinc levels in three (9%). The malnourished and normally nourished groups were similar with respect to demographics, precipitating factors, severity of diabetic ketoacidosis, treatment received, and outcome. However, the incidence and severity of therapy-related hypokalemia (100% vs. 72.7%; p = .05) and hypoglycemia (63.6 vs. 13.6%; p = .004) were significantly higher in the former as compared with the latter. The mean ± SD admission serum potassium levels were similar in both the groups (3.4 ± 0.8 mEq/L in the malnourished vs. 3.5 ± 0.7 mEq/L in the normally nourished) with the malnourished group showing a significant fall at 6 hrs after start the of diabetic ketoacidosis protocol (2.8 ± 0.8 mEq/L vs. 3.6 ± 0.7 mEq/L; p = .033), although the mean rate and dose of insulin infusion were similar. The fall in blood glucose (mean ± SD mg/dL) at 12, 24, and 36 hrs after onset of the diabetic ketoacidosis protocol was also significantly greater in the malnourished group as compared with the normally nourished diabetic ketoacidosis (195 ± 69.1 and 272.61 ± 96.3, p = .02; 171 ± 58.5 and 257 ± 96.3, p = .05; and 153.75 ± 49.6 and 241.71 ± 76.3, p = .04, respectively). The incidence of hypophosphatemia, hypomagnesemia, cerebral edema, renal failure, sepsis, and septic shock was similar in both the groups. There were two deaths, both resulting from complicating cerebral edema and renal failure and unrelated to the nutritional status of the patients. Conclusions: The incidence and severity of therapy-related hypokalemia and hypoglycemia were significantly higher in the malnourished as compared to the normally nourished diabetic ketoacidosis. Other diabetic ketoacidosis-related complications and outcome were similar in both the groups.

Relationship of High Sensitivity C-Reactive Protein Levels to Anthropometric and other Metabolic Parameters in Indian Children with Simple Overweight and Obesity.

CONTEXT High senstivity C-reactive protein (hsCRP) levels correlate well other parameters of obesity related metabolic syndrome (MS) and can be used as predictors of future cardiovascular disease risk. There is limited data on hsCRP levels in Indian children with simple obesity. AIM To study the relationship of hsCRP levels with various anthropometric as well as metabolic parameters in children with simple overweight and obesity. MATERIALS AND METHODS This case control study was conducted in Paediatric Endocrinology clinic of a tertiary care hospital in Northern India. Levels of hsCRP were estimated in 100 overweight and obese children (BMI between 85(th) and 95(th) percentiles according to age & gender specific CDC 2000 growth charts) aged between 6 and 16 years and in 100 nearly age and sex matched healthy controls. These levels were then correlated to various anthropometric (body mass index, BMI; waist circumference, WC; hip circumference, HC; waist hip ratio, WHR; blood pressure) and biochemical (fasting blood glucose, FBG; total cholesterol, TC; high-density lipoprotein-cholesterol, HDL-C; low-density lipoprotein cholesterol, LDL-C; very low-density lipoprotein-cholesterol, VLDL-C; triglycerides, TG) parameters. RESULTS Mean levels of hsCRP were significantly higher in the study group (3.92±2.20 versus 2.15±1.05 mg/L) as compared to controls. Significantly more (58% versus 10%) subjects in the study group had hsCRP (>3 mg/L). Of all the parameters studied, only BMI showed a positive correlation with hsCRP levels in the study group. Multiple logistic regression analysis for predicting outcome of high hsCRP showed positive correlation with BMI; with every 1 kg/m(2) increase in BMI, odds of high hsCRP level were increased by 37% (OR=1.37; 95% CI 1.23-1.53, p-value <0.0001). Mean values of all the biochemical parameters except HDL-C were significantly higher in the study group. CONCLUSION Levels of hsCRP were significantly elevated in overweight and obese children as compared to non-obese children. In addition, these patients also showed abnormalities of lipid and glucose metabolism.

Evaluation of micronutrient profile of North Indian children with cystic fibrosis: a case-control study

Background:Data on the micronutrient levels in children with cystic fibrosis (CF) are not available from developing countries, wherein the nutritional profile of children is quite different from that of Western countries.Methods:Levels of fat-soluble vitamins (A, D, and E) and trace metals (iron, copper, and zinc) were measured in 27 CF cases and 27 controls.Results:CF cases had significantly low levels of all studied micronutrients compared with controls, and the levels were even lower in cases with exacerbation than in stable CF cases. Prevalence of deficiency of vitamin D, vitamin E, iron, copper, and zinc was significantly higher in cases than in controls, whereas vitamin A deficiency was almost equal in both the groups.Conclusion:The prevalence of deficiency of vitamins A, D, and E and iron, copper, and zinc was high in CF cases, and their levels were significantly lower in cases than controls. CF cases should be regularly monitored for these micronutrients, and appropriate supplementation should be considered.

Daily Versus Alternate Day Thyroxine Therapy to Maintain Euthyroidism in Children With Congenital Hypothyroidism

Background: Daily administration of thyroxine has proven efficacy in treatment of children with hypothyroidism. However, the possibility of treatment with longer dosing intervals that offers flexibility and choice in maintaining euthyroid state has not been tested in children. Objectives: To study the efficacy of an alternate day regimen to maintain euthyroidism in children with congenital hypothyroidism Patients and Methods: Forty patients given alternate day therapy, while 30 children continued on their daily regimen were followed up at monthly intervals for 3 months. Clinical and laboratory assessments were performed at each follow up visit. Results: The clinical and anthropometric parameters remained similar in both groups of patients during the study indicating a maintained euthyroid state clinically. The thyroid profiles also remained within normal limits suggesting biochemical euthyroidism status with alternate day therapy. However the baseline serum aminotransferase levels showed mild elevation in patients on alternate day regimen and the difference persisted during the follow up visits. Higher HDL and lower TC and LDL levels suggested some beneficial effect of alternate day schedule on lipid profiles. Conclusions: In short-term, alternate day schedule can be effectively used to maintain clinical and biochemical euthyroid state in children with congenital hypothyroidism beyond 4 years of age.

Randomized Controlled Trial on Effect of Intermittent Early Versus Late Kangaroo Mother Care on Human Milk Feeding in Low-Birth-Weight Neonates:

Background: Breastfeeding at discharge among sick low-birth-weight (LBW) infants is low despite counseling and intervention like kangaroo mother care (KMC). Research aim: The aim was to study the effects of early initiation of KMC on exclusive human milk feeding, growth, mortality, and morbidities in LBW neonates compared with late initiation of KMC during the hospital stay and postdischarge. Methods: A randomized controlled trial was conducted in level 2 and 3 areas of a tertiary care neonatal unit over 15 months. Inborn neonates weighing 1 to 1.8 kg and hemodynamically stable were randomized to receive either early KMC, initiated within the first 4 days of life, or late KMC (off respiratory support and intravenous fluids). Follow-up was until 1 month postdischarge. Outcomes were proportion of infants achieving exclusive human milk feeding and direct breastfeeding, growth, mortality and morbidities during hospital stay, and postdischarge feeding and KMC practices until 1 month. Results: The early KMC group (n = 80) achieved significantly higher exclusive human milk feeding (86% vs. 45%, p < .001) and direct breastfeeding (49% vs. 30%, p = .021) in hospital and almost exclusive human milk feeding (73% vs. 36%, p < .001) until 1 month postdischarge than the late KMC group (n = 80). The incidence of apnea (11.9% vs. 20%, p = .027) and recurrent apnea requiring ventilation (8.8% vs. 15%, p = .02) were significantly reduced in the early KMC group. There was no significant difference in mortality, morbidities, and growth during the hospital stay and postdischarge. Conclusion: Early KMC significantly increased exclusive human milk feeding and direct breastfeeding in LBW infants.

A boy with prepubertal gynecomastia, hyperprolactinemia, and hypothyroidism.

Abstract Non-physiologic prepubertal gynecomastia with an identifiable cause is an uncommon condition. Hyperprolactinemia due to hypothyroidism is known to result in gynecomastia in adults, but this observation has not been reported in children. We discuss here a boy who developed gynecomastia after the first year of age and was later diagnosed with congenital hypothyroidism.

Secular trends of body mass index in North Indian children with Type 1 diabetes do not support the Accelerator Hypothesis

The accelerator hypothesis, which proposes a link between Type 1 diabetes (T1D) and Type 2 diabetes (T2D) through weight‐related insulin resistance, remains untested in developing countries with increasing rates of childhood obesity and T1D, and different ethnicities. We aimed to test the accelerator hypothesis in the context of a significant increase in T1D at our centre.
