Nationwide "Pediatric Nutrition Day" survey on the nutritional status of hospitalized children in South Korea.

Background/objectives: To evaluate the nutritional status and prevalence of malnutrition in hospitalized children at admission and during hospitalization in South Korea.

Subjects/methods: This first cross-sectional nationwide "Pediatric Nutrition Day (pNday)" survey was conducted among 872 hospitalized children (504 boys, 368 girls; 686 medical, 186 surgical) from 23 hospitals in South Korea. Malnutrition risk was screened using the Pediatric Yorkhill Malnutrition Score (PYMS) and the Screening Tool Risk on Nutritional status and Growth.

Acanthosis Nigricans as a Clinical Predictor of Insulin Resistance in Obese Children.

Purpose: This study aimed to evaluate the utility of acanthosis nigricans (AN) severity as an index for predicting insulin resistance in obese children.

Methods: The subjects comprised 74 obese pediatric patients who attended the Department of Pediatrics at Chosun University Hospital between January 2013 and March 2016. Waist circumference; body mass index; blood pressure; fasting glucose and fasting insulin levels; lipid profile; aspartate transaminase, alanine transaminase, glycated hemoglobin, C-peptide, and uric acid levels; and homeostatic model assessment insulin resistance (HOMA-IR) and quantitative insulin check sensitivity index (QUICKI) scores were compared between subjects with AN and those without AN.

Mesalizine-Induced Acute Pancreatitis and Interstitial Pneumonitis in a Patient with Ulcerative Colitis.

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease. Mesalizine for the first-line therapy of UC has adverse effects include pancreatitis, pneumonia and pericarditis. UC complicated by two coexisting conditions, however, is very rare.

Coexistence of gilbert syndrome and hereditary spherocytosis in a child presenting with extreme jaundice.

Gilbert syndrome is the most common inherited disorder of bilirubin glucuronidation. It is characterized by intermittent episodes of jaundice in the absence of hepatocellular disease or hemolysis. Hereditary spherocytosis is the most common inherited hemolytic anemia and is characterized by spherical, osmotically fragile erythrocytes that are selectively trapped by the spleen.

Combined aerobic and resistance exercise is effective for achieving weight loss and reducing cardiovascular risk factors without deteriorating bone health in obese young adults.

Purpose: Weight loss reduces cardiovascular risk factors in the obese. However, weight reduction through diet negatively affects long-term bone health. The aim of study was to determine the ability of combined aerobic and resistance exercise (CE) to reduce weight and cardiovascular risk without diminishing bone health.

Predictors of failure in medical students.

Purpose: This study aimed to identify the predictors of failure in medical students.

Methods: We conducted a 10-year follow-up survey of 231 medical students. The students' general characteristics, study-related factors, health-related behavior, and self-perceived health were examined using questionnaires that were given late in the first year of a premedical course.

Surgical treatment of cholelithiasis and choledocholithiasis in a 2-month-old premature and low birth weight infant.

Detection rates of cholelithiasis and choledocholithiasis in infants and children have increased since the introduction of ultrasonography, and surgical treatment is gradually tending to increase. However, for cholelithiasis and choledocholithiasis, controversies over etiology, diagnostic means, operation time, and operating method remain. Using ultrasonogram and magnetic resonance cholangiopancreatography (MRCP), we diagnosed cholelithiasis and choledocholithiasis in a premature and low birth weight infant who was admitted to the hospital with complaints of obstructive jaundice and alcoholic feces.
