BACKGROUND: Body mass index (BMI) and waist circumference (WC) are associated with cardiovascular (CV) risk factors. The aim of this study was to investigate the correlation of CV risk factors by cross-tabulating central obesity with multiple BMI categories in Korea. METHODS: A total of 328,789 adults aged 30–84 years who completed health assessments for National Health Insurance in 2012–2013 in Korea were examined. The participants were divided into two WC and five BMI groups to investigate CV risk factors, including metabolic syndrome (MetS), hypertension, diabetes, and dyslipidemia. RESULTS: The proportions of central obesity and obesity were 24.2% and 39.5% in men and 19.4% and 28.1% in women, respectively, according to the Korean Society for the Study of Obesity and World Health Organization Asia-Pacific Guideline criteria. The odds ratios (ORs) of CV risk factors in all sexes increased with increases in BMI and WC. Compared to the group with a normal WC and BMI, the adjusted ORs (95% confidence intervals) for having MetS and diabetes in the centrally obese and highest BMI group (BMI ≥30.0 kg/m²) were 35.95 (33.75–38.30) and 3.51 (3.26–3.77) in men and 29.22 (27.36–31.20) and 4.35 (4.02–4.70) in women, respectively. Participants who were centrally obese and obese (BMI ≥25.0 kg/m²) had the strongest correlation with all CV risk factors compared with those who were not centrally obese or obese. CONCLUSION: The presence of central obesity in multiple BMI categories may significantly identify individuals at increased risk of CV risk factors.

Most acinic cell carcinomas arise within the parotid gland: extraparotid origin is rare. We encountered three cases of extraparotid acinic cell carcinoma arising in the buccal or palatal region, or the submandibular gland. All three tumors presented as a painless, slow-growing mass. CT imaging indicated that they were well defined, homogeneously enhanced, round masses. In one case, sonography demonstrated relatively homogeneous low echogenicity.

A 48-year-old man visited the emergency room with right hip pain that started abruptly while walking out of the bathroom. Computed tomography showed an intraosseous mass in the femoral neck. The patient had a 15-year history of gout and had numerous bilateral tophi in his hands, feet, knees, and elbows. After operation, we diagnosed a pathological fracture due to intraosseous tophi. Patients with hip pain who have many subcutaneous tophi and long-standing gout should be diagnosed carefully. Peri-hip joint pain caused by gout is uncommon, however, if a patient complains of pain, a simple X-ray may be required. If intraosseous tophi are present, appropriate treatment (e.g., strict hyperuricemia control with or without prophylactic internal fixation), may be required before fracture occurs.

PURPOSE: To demonstrate the incidence and variation of the meniscofemoral ligament in Koreans. MATERIALS AND METHODS: A total of 100 MR studies of 95 patients were reviewed with special attention to the appearance and incidence of the meniscofemoral ligaments. The ligament of Wrisberg was classified according to proximal insertion: type I, insertion at the posterofemoral condyle ; type II, insertion at the distal portion of the posteriorcruciate ligament ; type III, insertion at the distal portion of the posterior cruciate ligament. On T2-weighted images, the high signal at the meniscal insertion of the meniscofemoral ligament was classified according to itsshape. RESULTS: The ligament o Humprey was observed in 17 cases and the ligament of Wrisberg was in 90:type I in41 cases;type II, 19 cases;type III, in 28 cases; unclassified, in 2 cases. In 77 cases, the cleft with high signal intensity was seen between the meniscofemoral ligament and the posterior cruciate ligament. CONCLUSION: From our results, the incidence of the ligament of Wrisberg on MRI was moe prevelant than the ligament of Humprey. An exact knowledge of the meniscofemoral ligament could be helpful in distinguishing it from pathologic lesions.

Kernicterus is a neurologic syndrome, resulting from the preferential deposition of unconjugated bilirubin in the globus pallidus, subthalamus, hippocampus, and brain stem. The characteristic finding of kernicterus revealed by T2-weighted MR imaging is irreversible, bilaterally symmetrical high signal intensities in the globus pallidus. We report an atypical case of kernicterus, in which follow-up MR imaging of the globus pallidus demonstrated reversible signal intensity.

PURPOSE: The purpose of this study was to evaluate spatiotemporal evaluation of pERK1/2 protein expression in the forebrain following hypoxic-ischemic (HI) injury in adult Sprague-Dawley rats. METHODS: HI injury was induced by occlusion of the bilateral common carotid artery (CCA) and respiration with 5% O2 hypoxic gas for 8 minutes, followed by unilateral release of CCA. RESULTS: Immunoreactivity for pERK1/2 protein in the bilateral cortex began to increase at 2 hours, reached peak levels at 6 hours, and then decreased by 24 hours after HI injury. In a cortical neuron, the expression of pERK1/2 protein was observed in all cellular components and processes including dendrites, cell body and nuclei at 6 hours, but persisted only in the cell body by 24 hours after HI injury. Temporal changes in the immunoreactivity for pERK1/2 protein in the hippocampus was very similar to that of the cortex following HI injury. In contrast, the temporal changes in the cellular distribution of pERK12 protein in hippocampal neurons was largely different from that of the cortex following HI injury. CONCLUSION: The results of the present study suggest that HI injury causes an early activation of ERK1/2 signaling with a differential cellular distribution of pERK1/2 protein among different forebrain structures. Further study needs to be done in order to elucidate a possible role of ERK1/2 signaling for neural damage in the adult rodent HI model.

PURPOSE: The estimation of fluid deficit is crucial to the proper management of dehydrated children. Without well-documented serial weights on the same scale, the estimation of any given child's fluid deficit is imprecise and dependent largely on subjective clinical criteria. Despite the abundance of literature on clinical and laboratory evaluation of dehydration, few studies have focused on serum uric acid. So, we examined the usefulness of serum uric acid in gastroenteritis patients with dehydration. METHODS: Medical records of 90 gastroenteritis patients were retrospectively reviewed. By the body weight loss, we classified patients with mild, moderate, and severe dehydration groups. We studied the relevance of laboratory data (BUN, creatinine, serum bicarbonate, glucose, urine specific gravity, and uric acid) with dehydration. RESULTS: 54 children (60%) were dehydrated mildly, 24 (26%) dehydrated moderately, and 12 (14%) dehydrated severely. Statistically significant differences in BUN, creatinine, serum bicarbonate, glucose, and urine specific gravity could not be observed. But there was significant relationship between uric acid and the degree of dehydration. Data analysis suggested that the level of 7.0 mg/dL is the best cut-off value for predicting the development of moderate or severe dehydration. At this cut-off value, the sensitivity and specificity were 66.6% and 87.1%. CONCLUSION: Our study supports that the measurement of serum uric acid with traditional scales is useful for predicting the development of dehydration. But, in order to be used as the indicator for proper treatment at an earlier stage, further validation about serum uric acid is necessary.

Lower esophageal ring is unique disorder of the esophagus. It is composed entirely of mucosal fold, containing no muscle or scar tissue. It is one of the most common causes of dysphagia of adults, but an unusual cause of dysphagia in pediatric age group. This 14-year old male patient experienced progressive dysphagia for several years. Approximately 15 months prior to this visit, he began having trouble swallowing solid foods and lost body weight during the period. An esophagogram shows lower esophageal ring. Esophagoscopy revealed the ring just above the esophagogastric mucosal junction. The ring made a concentric narrowing that appeared to form a thin shelf in the lower esophagus. The diameter of the esophageal lumen was about 4mm. Then pneumatic balloon dilatation was performed by Rigiflex (r)-TTS dilator under fluoroscopic control. The ring was widened without resistance and symptom of dysphagia relieved. After pneumatic dilatation the diameter of the esophageal lumen increased to 12mm. We report a case of lower esophageal ring in childhood and review of the literatures.

Angiomyxolipoma is a rare variant of lipoma, which is described by Mai, 1996, at first. The nine cases of which have been reported to date. Microscopically, the lesion consists of adipose tissue with the paucicellular myxoid areas and fat tissue with numerous thin, dilated, and congestive blood vessels. The reported cases mostly located to the superficial layer on the scalp, subungual, extremities in adults. We report one case of angiomyxolipoma located in the submuscular and parosteal area in the distal femur around knee joint in a child.
