PURPOSE: Food allergies can affect the growth and nutritional status of children with atopic dermatitis (AD). This study was conducted to determine the association between the number of sensitized food allergens and the growth and nutritional status of infants and young children with AD. METHODS: We studied 165 children with AD, aged 5 to 47 months, and who visited the Atopy Clinic of the Seoul Medical Center. We recorded the birth weight, time at which food weaning began, scoring of atopic dermatitis (SCORAD) index, eosinophil counts in peripheral blood, and total serum IgE and specific IgE to six major allergens (egg white, cow's milk, soybean, peanut, wheat, and fish). The height and weight for age and weight for height were converted to z-scores to evaluate their effects on growth and nutritional status. Specific IgE levels > or =0.7 kUA/L, measured via the CAP assay, were considered positive. RESULTS: As the number of sensitized food allergens increased, the mean z-scores of weight and height for age decreased (P=0.006 and 0.018, respectively). The number directly correlated with the SCORAD index (r=0.308), time at which food weaning began (r=0.332), eosinophil counts in peripheral blood (r=0.266), and total serum IgE (r=0.394). Inverse correlations were observed with the z-scores of weight for age (r=-0.358), height for age (r=-0.278), and weight for height (r=-0.224). CONCLUSIONS: A higher number of sensitized food allergens was associated with negative effects on the growth and nutritional status of infants and young children with AD. Therefore, a thorough evaluation of both growth and nutritional status, combined with adequate patient management, is crucial in pediatric AD patients presenting with numerous sensitized food allergies.

Portal vein gas and pneumatosis cystoides intestinalis are uncommon conditions and have been associated with poor prognosis. They are most commonly caused by necrotizing enterocolitis but may have other causes, and they can be associated with necrotizing and ischemic colitis, intra-abdominal abscess, small bowel obstruction, diverticulitis, colon cancer, and acute pancreatitis. With the more frequent use of computed tomography (CT) scans, portal vein gas and pneumatosis cystoides intestinalis have been increasingly detected in recent years. Because of its high mortality rate, necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis may be treated with emergent exploratory laparotomy. We report a case of necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis in a 47-year-old man treated with intensive medical management and delayed operation due to unstable condition and surgical mortality. He had good clinical results without complications after the delayed operation.

PURPOSE: Osteoarticular infections in children and adolescents are important because it can cause functional compromise if appropriate treatment is delayed. Therefore, this study was designed to describe the clinical presentations and causative organisms of osteoarticular infections in children and adolescents in order to propose early diagnosis method and an appropriate empiric antimicrobial therapy. METHODS: Forty-two medical records were reviewed retrospectively, which were confirmed as osteomyelitis (OM) or septic arthritis (SA) at Department of Pediatrics or Orthopedic Surgery in patients under 18 years old of Ewha Womans University Mokdong Hospital from March 2008 to March 2015. RESULTS: We identified 21 cases of OM, 13 cases of SA and 8 cases of OM with SA. There were 31 males and 11 females and mean age was 7.1 years old. The most common symptoms were pain and tenderness of involved site. Major involved bones were femur (10 cases, 34.5%), tibia (7 cases, 24.1%) and major involved joints were hip (9 cases, 42.9%), and knee (5 cases, 23.8%). Increased serum C-reactive protein and erythrocyte sedimentation rate were observed in 37 cases (88.1%) respectively. Magnetic resonance imaging was performed in 40 cases among 42 cases and was used to demonstrate osteoarticular infections and other adjacent infections. Nine cases (23.7%) among 38 cases and 20 cases (50.0%) among 40 cases were positive in blood culture and infected site culture respectively. The most common causative organism was Staphylococcus aureus, which was represented in 22 cases (75.9%), of which nine cases (40.9%) were resistant to methicillin. CONCLUSIONS: S. aureus was the most common causative organism of osteoarticular infections in children and adolescents and the proportion of MRSA was high in this study. Therefore, we recommend vancomycin as the first empiric antimicrobial therapy and suggest that further study is necessary to elucidate an appropriate guideline for treatment which takes into account MRSA proportion.

PURPOSE: Since 1988, the annual or biannual survey was conducted by Korean Association of Smoking and Health (KASH) to examine the smoking rate, knowledge and attitude on smoking of students attending middle and high school in Korea. The objective of this study was to investigate the test-retest reliability of self-administered smoking questionnaire for Korean middle and high school students. METHODS: For the test-retest study, we sampled 30 school among 106 schools which participated in annual survey on June of 2002. Among 30 schools, 26 schools (86.7%) were responded for this study. RESULTS: 1) For the subjects of 1st and 2nd surveys, there were no difference on smoking related variable including attitude, knowledge, perceived health status, father's smoking status, friend's smoking status, willingness to smoke, and readiness to quit smoking 2) For middle school students among male, current smoking rates were 3.5% for 1st survey and 3.0% for 2nd survey, which was statistically no significant. For high school students, however, current smoking rate of 1st survey was higher (21.1%) than that of 2nd (18.2%), although the rate was not significantly differed. 3) For middle school students among female, current smoking rates were 1.1% for 1st survey and 3.3% for 2nd survey, which was statistically no significant. Corresponding rate for high school students were 9.8% and 11.4%, respectively. CONCLUSION: The results indicated that smoking questionnaire has been conducted by KASH is reliable for use in estimation for prevalence of smoking for middle and high school students.

Attention-deficit hyperactivity disorder (ADHD) occurs with a high prevalence of comorbid disorders, and these comorbid disorders can affect assessment, clinical symptoms, prognosis, and treatment strategies for children with ADHD. The goal of this study was to develop a clinical practice guideline for ADHD and its specific comorbid disorders. Due to limited numbers of previous clinical studies, current recommendations are based on literature review and expert consensus among Korean child and adolescent psychiatrists. We suggest the use of multidisciplinary evaluations, interview techniques, and assessment tools in order to differentiate major comorbid disorders from ADHD. Specific ADHD comorbid disorders (e.g., medical comorbidity, oppositional defiant disorder, conduct disorder, bipolar disorder, major depressive disorder, anxiety disorder, specific learning disorder, tic disorder, and substance use disorder) have suggested treatment protocols that include pharmacological and behavioral treatments. Children and adolescents with ADHD may have comorbid disorders. The use of current clinical practice guidelines will be helpful when treating ADHD children with comorbid disorders.

BACKGROUND: This study aimed to evaluate the quality of surgical antibiotic prophylaxis (SAP) in a tertiary hospital. METHODS: Medical, anesthetic, and nursing records from the 27,320 procedures conducted in a tertiary hospital during 2012 were retrospectively reviewed. Three clinical performance indicators of SAP (selection of antibiotic, timing of the first administration, duration of prophylaxis) were included as part of the National Hospital Evaluation Program (NHEP) of the Health Insurance Review and Assessment Service. In addition, 2 other parameters were assessed according to recent guidelines (weight-based initial dosing for obesity, intraoperative re-dosing for excessive blood loss, and prolonged duration of procedures). RESULTS: Prophylactic antibiotics were administered in 19,637 (71.8%) of 27,320 total procedures. Quality of the 3 performance indicators was higher in the types of operations included in NHEP than in other procedures. However, additional doses were administered in 15 (1.2%) of 1,299 surgical procedures that lasted more than twice the half-life of the antibiotic used, and in 9 (3.3%) of 273 procedures with excessive blood loss greater than 1,500 mL. NHEP and non-NHEP results did not differ significantly. CONCLUSION: Three SAP quality indicators showed more improvement in NHEP surgical procedures than in non-NHEP, but the other parameters did not perform well regardless of NHEP assessment. Therefore, more measures to improve the appropriateness of SAP should be developed.

Primary small cell carcinoma of the paranasal sinuses is extremely rare. It is aggressively locally invasive, with high recurrence and metastatic rates. A combination of systemic chemotherapy and locoregional treatment, such as radiotherapy, is currently recommended based on the treatment of small cell carcinoma of lung. We report a case of small cell carcinoma originating from the maxillary sinus with distant metastasis at the time of diagnosis. The patient had a good initial therapeutic response to etoposide-cisplatin chemotherapy, but the cancer progressed after the sixth cycle of chemotherapy and the prognosis was poor.

OBJECTIVES: Kikuchi-Fujimoto disease (KFD) is characterized by lymphadenopathy and fever, and is usually self-limited. This study analyzed the clinical characteristics of pediatric patients with KFD. METHODS: This retrospective, observational, single-center study was conducted in South Korea from March 2008 to October 2015. KFD was diagnosed based on clinical, radiological or histological findings and excluded when there were any other causes of lymphadenopathy. Medical records were reviewed for clinical and laboratory manifestations. RESULTS: A total of 35 cases were included. The mean patient age was 12.1±2.9 years (range, 5 to 17 years); the male-to-female ratio was 1:0.8. The main clinical manifestations were cervical lymphadenopathy and fever in 34 cases (97%). The mean duration of fever was 12.2±8.3 days (range, 2 to 37 days). We noted enlargement of lymph nodes in the cervical, mesenteric (n=5, 14%), axillary (n=2, 6%), and inguinal (n=1, 3%) regions. Hepatosplenomegaly, loss of appetite, and rash were observed. On laboratory examinations, elevation of ferritin, leukopenia, and positivity for anti-nuclear antibodies were frequently observed. Twelve patients underwent biopsy and 23 cases were diagnosed by radiological findings. The mean duration of hospitalization for all cases was 7.9±2.9 days (range, 3 to 13 days) and steroids were administered in 10 cases. KFD recurrence was observed in 2 cases (5.7%) with the time to relapse of 7 months and 4 years. There were no cases with systemic lupus erythematous or other autoimmune disease. CONCLUSION: KFD should be considered in pediatric patients with lymphadenopathy and prolonged fever. Patients with KFD should be monitored for recurrence and the development of autoimmune disease.

The prevalence of small bowel cancer is relatively low. The abdominal pain that patients with small bowel cancer present as a symptom is non-specific and often interpreted as a normal finding on radiographic studies. To prevent delayed diagnosis of small bowel cancer, practitioners must maintain a certain level of suspicion. We report a case of delayed diagnosis of jejunal cancer as it was misdiagnosed as gastroparesis. A 69-year-old woman complained of recurrent nausea and vomiting. At the beginning of her hospitalization, we could not diagnose mechanical obstruction through esophagogastroduodenoscopy and abdominal computed tomography. A gastric emptying study revealed delayed gastric emptying. Although the patients received treatments, including administration of prokinetics and botulinum toxin injection, for gastroparesis, her symptoms aggravated. Subsequently, plain radiography of the abdomen revealed a double-bubble sign. Abdominal computed tomography was performed under the suspicion of small bowel obstruction; however, the diagnosis was not clear. Consequently, exploratory laparoscopy was performed. She underwent surgical management, including small bowel segmental resection and duodenojejunostomy, due to the jejunal mass with involvement of the stomach, pancreatic head, and mesentery of the transverse colon. The postoperative pathological results revealed a moderately differentiated adenocarcinoma of the jejunum.
