BACKGROUND: We investigated the association between socioeconomic status and adherence to health check-ups in a Korean population aged 40 years or older. METHODS: This cross-sectional study included 12,311 participants who participated in the 2010–2012 Korean National Health and Nutrition Examination Survey. Self-reported questionnaires were used to assess each participant's socioeconomic status (household income, occupation, and education) and adherence to health check-ups. RESULTS: Men with a higher income (highest vs. lowest: odds ratio [OR], 1.799; 95% confidence interval [CI], 1.296–2.497) and men with a higher education level (≥12 vs. < 6 years: OR, 1.488; 95% CI, 1.078–2.054) and office workers compared with manual workers (men: OR, 1.431; 95% CI, 1.077–1.902; women: OR, 1.783; 95% CI, 1.256–2.532) appeared to undergo more health check-ups. In particular, men and women with a higher income and education appeared more likely to undergo opportunistic health check-ups (men: highest vs. lowest income: OR, 2.380; 95% CI, 1.218–4.653; ≥12 vs. < 6 years education: OR, 2.121; 95% CI, 1.142–3.936; women: highest vs. lowest income: OR, 4.042; 95% CI, 2.239–7.297; ≥12 vs. < 6 years education: OR, 2.475; 95% CI, 1.283–4.775). CONCLUSION: A higher socioeconomic status was associated with a higher rate of participation in health check-ups. More efforts are needed to identify the factors associated with disparity in adherence to health check-ups.

PURPOSE: To investigate trends in blood pressure (BP) and hypertension prevalence in Korea. MATERIALS AND METHODS: Based on the Korean National Health and Nutrition Examination Survey (KNHANES) I (1998), II (2001), III (2005), IV (2007–2009), V (2010–2012), and VI (2013–2014), 56077 participants (23974 men and 32103 women) were included. RESULTS: Mean systolic BP (SBP) and diastolic BP (DBP) decreased in both sexes (male SBP: 128.1 to 120.2 mm Hg, male DBP: 82.0 to 78.5 mm Hg; female SBP: 125.7 to 116.0 mm Hg and female DBP: 77.4 to 73.2 mm Hg from the KNHANES I–VI). The age-standardized prevalence of hypertension was significantly decreased in both sexes (male; 33.3% to 30.3%, female; 28.7% to 22.7%, all p for trend < 0.001). Regardless of taking anti-hypertensive medication or not, SBP and DBP declined universally in both sexes. Compared to the KNHANES I, the odds ratios (95% confidence intervals) of the KNHANES II to VI for less-than-normotensive and less-than-hypertensive BP increased in both sexes. CONCLUSION: Mean BP levels in both sexes and hypertension prevalence showed downward trends during the 16-year period.

Patients with inflammatory bowel disease (IBD) have an elevated risk of venous thromboembolism compared with the general population. The most common sites of venous thromboembolism in IBD patients are the deep veins of the legs, the pulmonary system, and portal and mesenteric veins. However, cerebral venous thrombosis is rarely associated with IBD. This report describes a case of cerebral venous thrombosis in a patient with Crohn's disease. A 17-year-old girl, diagnosed 4 years earlier with Crohn's disease, presented with headache and vomiting. Magnetic resonance imaging of the brain with venography showed venous thrombosis in the cortical veins, superior sagittal sinus, right transverse sinus, and right internal jugular vein. The patient immediately started anticoagulation therapy with intravenous heparin infusion followed by daily oral rivaroxaban 10 mg. Follow-up imaging after 2 weeks showed resolution of the thrombosis, with recanalization of the cortical veins, superior sagittal sinus, right transverse sinus, and right internal jugular vein. She continued rivaroxaban therapy for 6 months, and remained well, without neurologic sequelae. A high level of concern for cerebral venous thrombosis may be important when treating active IBD patients, because anticoagulation treatment can prevent fatal complications.

BACKGROUND: It has not been determined which obesity index might be most appropriate to predict nonalcoholic fatty liver disease in Asian populations. This study aimed to evaluate the usefulness of the waist-to-height ratio in assessing patients with nonalcoholic fatty liver disease and to identify the optimal cut-off values useful for predicting nonalcoholic fatty liver disease. METHODS: Receiver operating characteristic curve analyses were conducted in order to assess the accuracy of the waist circumference, body mass index, and waist-to-height ratio for detecting nonalcoholic fatty liver disease among 616 women aged 20 years or older. To evaluate the optimal value of anthropometric indices, the Youden J-index (sensitivity+specificity-1) was used. RESULTS: The area under the ROC curve of waist-to-height ratio was highest among anthropometric obesity indices as follows: 0.776 (0.731-0.822) for waist circumference, 0.775 (0.728-0.822) for body mass index, and 0.792 (0.748-0.836) for waist-to-height ratio, respectively. Using a waist-to-height ration cut-off value of 0.49, the sensitivity and specificity for detecting nonalcoholic fatty liver disease were 72.3 % and 74.7%, respectively. CONCLUSION: These results demonstrated that the waist-to-height ratio may be a better obesity index for identifying individuals at risk for nonalcoholic fatty liver disease in Korean women.

Lymphangioma is a benign vascular lesion with characteristics of subepithelial tumor which can proliferate in the lymphatic system. Lymphangioma of the small-bowel mesentery is rare, having been reported in less than 2% of all lymphangiomas. Lymphangioma does not require any specific treatment because it is absolutely a benign tumor. However, surgical exploration is rarely required for cases with disease-related symptoms or complications, or for those misdiagnosed as a malignant lesion. We recently experienced a case of mesenteric cavernous lymphangomas in a 53-year-old female who was misdiagnosed as having a liposarcoma. The final diagnosis was confirmed by a pathologic examination of the specimen that was obtained via laparoscopic exploration. Herein, we report a very rare case of mesenteric cavernous lymphangioma along with a brief review of relevant literature.

PURPOSE: To evaluate the safety and feasibility of a simplified zero ischemia technique using kidney donor computed tomographic (CT) angiography and conventional laparoscopic bulldog clamps. MATERIALS AND METHODS: We conducted a review of seven robot-assisted partial nephrectomies (RAPNs) performed by a single surgeon from January 2012 to May 2012. Using a simplified protocol of 3-dimentional reconstruction, tertiary arterial branches supplying the tumor were selectively clamped prior to resection. We used conventional laparoscopic bulldog clamps instead of microsurgical vessel clamps. The patients' demographic information, perioperative outcomes, pathologic outcomes and pre- and postoperative renal functions up to 3 months follow-up were analyzed. RESULTS: RAPN were successfully performed for seven complex renal hilar tumors. There were no significant differences in the total operation time, estimated blood loss or postoperative outcomes compared with published literature on standard RAPN. Negative surgical margins were reported in all cases. CONCLUSIONS: We presented a simplified-zero ischemia technique using kidney Donor CT angiography and conventional laparoscopic bulldog clamps. We have also demonstrated its safety and feasibility in patients with complex renal hilar tumors. This modified technique can be easily adopted by most surgeons who are currently performing RAPN.

Neuroendocrine carcinomas from an unknown primary site are uncommon. The authors report on a case of neuroendocrine carcinoma in a perigastric lymph node (LN) with no primary site. A 52-year-old male patient with early gastric adenocarcinoma underwent treatment by endoscopic submucosal dissection, and, six months later, findings on a computed tomographic scan of the abdomen revealed a LN enlargement measuring 2.0 cm in the perigastric region. The patient underwent subtotal gastrectomy and regional LN dissection under a suggestive preoperative diagnosis of gastric adenocarcinoma with LN metastasis. However, microscopically, no residual tumor was found in the stomach, and the perigastric LN showed poorly differentiated neuroendocrine carcinoma (PDNEC). After an extensive workup, no primary site was identified. The patient also received four cycles of etoposide and cisplatin. Despite its extremely rare incidence, this case suggests that PDNEC of an unknown primary site is limited to a single site, and that resection should be considered in combination with chemotherapy.

Although metastasis is relatively frequent in cases of renal cell carcinoma (RCC), metastasis in the cervical or supraclavicular lymph node (LN) is relatively rare. Moreover, cases of metastatic RCC with a non-identifiable kidney mass are extremely rare. Here, the authors report a case of metastatic RCC in a supraclavicular LN without a primary kidney lesion. A 69-year-old man presented with a progressively enlarging right supraclavicular mass. Incisional biopsy of the affected supraclavicular LN was performed, and histological examination revealed metastatic RCC. However, no tumor was found in either kidney, despite various examinations. The patient was treated with radiotherapy followed by sunitinib. After three months on sunitinib, a follow-up computed tomography scan revealed that the supraclavicular LN had markedly decreased, and after 20 months, the disease had not progressed. This case suggests that, even when there is no primary kidney lesion, clinicians must consider the possibility of metastatic RCC when evaluating patients with clear cell carcinoma with an unknown primary site.

The foreign bodies in vagina cause intense inflammation. Genital complaints in patients could indicate the presence of a vaginal foreign object. Vaginal bleeding and blood-stained, foul-smelling discharge are considered to be the main clinical manifestations of vaginal foreign bodies, and toilet tissue reported as the most commonly found foreign body. The insertion of foreign bodies into the vagina is not uncommon but presentation as lower abdominal pain in an gynaecological clinic is rare. The causes of insertion are sexual stimulation, sexual abuse, accident of post-surgery and most cases find a solution after vaginal speculum examination. We describe a case of foreign body in the vagina of a patient presenting with chronic lower abdominal pain but undetectable and unrecognized in general examination.

OBJECTIVES: We analyzed the relationship between body composition, metabolic parameters, and lumbar and femur bone mineral density (BMD) in pre-and post-menopausal women. METHODS: Of 394 females who participated in a medical check-up program, anthropometric measurements and fasting glucose levels and lipid profiles were measured. Body composition analysis was performed using the bioimpedence method and the BMD of the lumbar spine, femur neck, trochanter, ward's triangle, and total were measured by dual energy X-ray absorptiometry. RESULTS: The mean age was 49.5 +/- 9.8 years, and among the subjects, 203 (51.5%) were pre-menopausal and 191 (48.5%) were post- menopausal women. Skeletal muscle mass, fat- free mass, lean body mass, and basal metabolic rate had a positive correlation with the lumbar and femur spine BMD, even after adjustment for age and weight in pre-menopausal women. The abdominal fat ratio, fat mass, waist circumference, percent fat, and total cholesterol had a negative correlation with the lumbar and femur spine BMD, even after adjustment for age and weight in pre-menopausal women. The lean body mass in the legs and trunk, skeletal muscle mass, and fat free mass had a positive correlation with the BMD of the lumbar spine and femur neck, unlike the lean body mass of the arms did not, after adjustment for age and weight in post-menopausal women. CONCLUSION: In pre- and post-menopausal Korean women, body composition, lean body mass, fat -free mass, and skeletal muscle mass were positive correlates, and fat mass and percent fat were negative correlates with the lumbar spine and femur BMD.
