Background: Sweet syndrome is characterized by tender erythematous plaques and nodules with predominantly dermal neutrophilic infiltrates. Sweet syndrome is relatively rare in children and adolescents. To date, only a few cases have been reported in Korean literature. Objective: The aim of this study was to investigate the clinical and histopathological features of Sweet syndrome in Korean children and adolescents. Methods: A retrospective study was conducted on 15 pediatric patients (aged ＜18 years) who were diagnosed with Sweet syndrome between 1991 and 2019. We reviewed the clinical and histopathological features of Sweet syndrome. Results: The age of the 15 patients ranged from 4 months to 17 years. Among the 15 patients with Sweet syndrome, nine patients were females and six patients were males. Most patients (80%) had lesions on the upper extremities. Fever and tenderness (60%) were the most commonly associated symptoms. Transient infections such as upper respiratory infection or gastroenteritis were the most common identifiable cause, observed in 40% of patients. Histopathologically, dermal neutrophilic infiltration was observed in all patients. All patients were treated with systemic corticosteroids and showed a good response, although 26.7% of the patients experienced symptom recurrence.During the follow-up period, there were no incidences of any complications or extracutaneous manifestations in the patients. Conclusion In contrast to previous reports of pediatric Sweet syndrome, female predominance was observed in this study. Transient infection was the most common factor. All patients responded well to systemic corticosteroid therapy without complications or extracutaneous manifestations during the follow-up period.

BACKGROUND: Insulin resistance, decreased response of peripheral tissue to normal insulin levels, is known to be related to cardiometabolic diseases. Cardiopulmonary fitness is also considered to be related to these comorbidities. Therefore, we investigated the relationship between insulin resistance and cardiopulmonary fitness by performing a 3-minute step test in a Korean non-diabetes mellitus (DM) population. METHODS: A total of 118 non-DM subjects were enrolled during their routine health check-up. Insulin resistance was measured by calculating homeostatic model assessment-insulin resistance (HOMA-IR), and a 3-minute step test was performed to measure cardiopulmonary fitness. RESULTS: Post-60 seconds exercise heart rate after 3-minute test (R60 heart rate) was correlated with age (r = -0.21, P = 0.02), education (r = 0.17, P = 0.04), body mass index (r = 0.23, P = 0.01), waist circumference (r = 0.28, P < 0.01), fasting insulin (r = 0.28, P < 0.01), HOMA-IR (r = 0.25, P < 0.01), low density lipoprotein-cholesterol (r = 0.28, P < 0.01), high sensitivity C-reactive protein levels (r = 0.22, P = 0.02), and baseline heart rate (r = 0.56, P < 0.01). In a step-wise multiple regression analysis, baseline heart rate (beta = 0.79, P < 0.001), HOMA-IR (beta = 0.65, P = 0.02), and systolic blood pressure (beta = 0.15, P = 0.03) were identified as explanatory variables for R60 heart rates. CONCLUSION: Our results suggested that cardiopulmonary fitness was associated with insulin resistance in non-DM patients of a university hospital in Korea. Further studies are needed to elucidate the underlying mechanisms.

The Overlap syndrome is characterized by a combination of the major hepatobiliary autoimmune diseases such as autoimmune hepatitis, primary biliary cirrhosis and primary sclerosing cholangitis. It is frequently accompanied by inflammatory bowel disease. Chronic lymphoplasmacellular osteomyelitis is characterized by recurrent episodes of bacterial osteomyelitis and is associated with autoimmune diseases (especially inflammatory bowel disease). We report the case of a girl who was diagnosed with ulcerative colitis and autoimmune hepatitis at 4 years of age and with the overlap syndrome with primary sclerosing cholangitis at 6 years. At 9 years, she was diagnosed with chronic lymphoplasmacellular osteomyelitis.

PURPOSE: Ingested foreign bodies are removed by endoscopy, surgery or spontaneous passage, however, the decision of therapeutic modality chosen depends on the type, size, shape and location of the ingested foreign bodies. Therefore, this study was conducted to investigate the rate and characteristics of foreign bodies that were passed spontaneously out of the intestine. METHODS: One hundred and sixty patients who visited Samsung Medical Center for treatment of gastrointestinal foreign bodies between January 2001 to July 2007 were enrolled in this study. Related data was colleted by reviewing the medical records of patients with proven foreign bodies retrospectively, as well as by conducting phone interviews with the parents of the patients. All cases were classified based on the nature and location of the ingested foreign body, as well as whether it was treated by spontaneous passage. RESULTS: Of the 160 cases involving the passage of foreign bodies in children were included in this study (95 boys and 65 girls), endoscopic removals, operative removals or spontaneous passages were conducted in 80, 3 and 77 patients, respectively. The spontaneous passage rates for each type of object were as follows; coins (36.5%), bead and baduk stones (83.3%), long and sharp materials (52.6%), magnets (69.2%) and disc batteries (50.0%). In cases involving round-shaped foreign bodies, such as coins, the diverse spontaneous passage rates were more diverse. When foreign bodies were stuck below esophagus, similar sized coins and baduk stones had spontaneous passage rates greater than 80% regardless of age. CONCLUSION: It is better for clinicians to wait for spontaneous passage to occur in cases involving coins or round-shaped foreign bodies that are located at or below the stomach.

PURPOSE: This study was undertaken to evaluate the long-term treatment of esophageal strictures in children with corrosive esophagitis and to determine the effect of self-bougienage on recurrent strictures. MATERIALS AND METHODS: We reviewed the medical records of nine children that were treated for corrosive esophageal strictures from May 2000 to May 2008. Six males and three females were included and their average age was 30 months. Six patients had ingested acids, two patents had ingested alkali, and one ingested an unknown agent. RESULTS: The interval between caustic ingestion and esophageal stricture ranged from one to eight weeks. The average length of the esophageal strictures was 3.8 cm (range, 1 to 9.2 cm). Four patients had a long segment stricture (longer than 5 cm) and one patient had multiple strictures. The most common site of involvement was the upper third followed by the mid third of the esophagus. Eight patients received repeated dilatation using a balloon catheter or bougie dilator. Among the eight patients, two patients had complete resolution of symptoms and six patients required surgery. Among five patients that developed restenosis of the esophageal anastomosis site, three patients had improved symptoms after self-bougienage and two patients had improved symptoms with repeated balloon dilatation or endoscopic bougienage. There were no complications in these patients. CONCLUSION: Although a small number of patients were studied, self-bougienage was safe, less invasive, and effective for the management of esophageal restenosis in patients who required frequent dilation after surgery.

BACKGROUND: The purpose of this study was to compare the physical activity and caloric intake trends of lipid-lowering drug users with those of non-users among Korean adults with dyslipidemia. METHODS: This study was a repeated cross-sectional study with a nationally representative sample of 2,635 Korean adults with dyslipidemia based on the 2010-2013 Korea National Health and Nutrition Examination Survey. Physical activity was assessed using the International Physical Activity Questionnaire, and caloric intake was estimated through 24-hour dietary recall. All statistical analyses were conducted using IBM SPSS ver. 21.0 (IBM Co., Armonk, NY, USA). The changes in physical activity and caloric intake were investigated for lipid-lowering drug users and non-users using generalized linear models. RESULTS: The proportion of lipid-lowering drug users in the 2010-2013 survey population increased from 3.5% to 5.0% (P<0.001). Among adults of dyslipidemia, total of 1,562 participants (56.6%) reported taking lipid-lowering drugs, and 1,073 (43.4%) reported not taking lipid-lowering drugs. Drug users were more likely to be older and less educated and to have a diagnosis of diabetes, higher body mass index, and lower low density lipoprotein cholesterol level. Physical activity trends were tested separately for the lipid-lowering drug users and non-users, and a significant decrease was found among the drug users during the study period. Physical activity among the drug users in 2013 was 38% lower (1,357.3±382.7 metabolic equivalent [MET]; P for trend=0.002) than in 2010 (2,201.4±442.6 MET). In contrast, there was no statistically significant difference between drug users and non-users in the trend of caloric intake during the same period. CONCLUSION: Physical activity significantly decreased among lipid-lowering drug users between 2010 and 2013, which was not observed among non-users. The importance of physical activity may need to be re-emphasized for lipid-lowering drug users.
