Isolated lateral ventricle after ventriculoperitoneal shunt for hydrocephalus can occur by obstruction of foramen of Monro. Two cases of isolated lateral ventricles after ventriculoperitoneal shunt are reported. Patients showed neurological deterioration and brain CT scan revealed unilateral dilatation of lateral ventricle after ventriculoperitoneal shunt. They were successfully managed by another shunt system into dilated lateral ventricle.

The objectives of this study are to investigate the prevalence of occupation related carpal tunnel syndrome(CTS) among workers in a condom industry; to analyse the sensitivity and specificity of clinical signs or symptoms such as hand diagram, Tinel's sign and Phalen's sign in carpal tunnel syndrome; and to test vibration threshold test using audiometry as a technically easy and noninvasive method in the diagnosis of carpal tunnel syndrome in stead of nerve conduction velocity(NCV). The study group was divided into exposed group(39 cases)and non-exposed group(48 cases) based on whether or not excessive use of wrist movements exist. 1. There are statistically significant differences in symptoms and signs of carpal tunnel syndrome such as hand diagram, Tinel's sign and Phalen's sign between exposed and non-exposed group(p<0.05). 2. Six cases(9 hands) were confirmed as carpal tunnel syndrome by NCV. Five cases(7 hands) belonged to exposed group, 1 case(2 hands) to nonexposed group. As there are significant differences in prevalence of carpal tunnel syndrome between two groups(p<0.05), excessive use of wrist in occupation is a risk factor of carpal tunnel syndrome. 3. When we use NCV as a gold standard in the diagnosis of carpal tunnel syndrome, sensitivity and specificity of hand diagram, Tinel's sign and Phalen's sign is as followed; hand diagram; sensitivity 88.9%, specificity 84.2%. Tinel's sign; sensitivity 55.6%, specificity 72.8%. Phalen's sign; sensitivity 14.3%, specificity 88.4%. Among above clinical signs and symptoms, hand diagram is the best clinical screening test. 4. The differences of vibration threshold between median and ulnar nerve at the same time are useful in the diagnosis of carpal tunnel syndrome but the time change of vibration threshold of median nerve over time are not sensitive enough. It is concluded that vibration threshold between median and ulnar nerve at the same time can be used as a supplementary or alternative criterion to indicate that the nerve dysfunction is located in the carpal tunnel.

OBJECTIVES: Elevated serum uric acid (UA) has been known to be associated with the prevalence of metabolic syndrome (MetS). However, no prospective studies have examined whether serum UA levels are actually associated with the development of MetS. We performed a prospective study to evaluate the longitudinal effects of baseline serum UA levels on the development of MetS. METHODS: A MetS-free cohort of 14 906 healthy Korean men, who participated in a medical check-up program in 2005, was followed until 2010. MetS was defined according to the Joint Interim Statement of the International Diabetes Federation Task Force on Epidemiology and Prevention. Cox proportional hazards models were performed. RESULTS: During 52 466.1 person-years of follow-up, 2428 incident cases of MetS developed between 2006 and 2010. After adjusting for multiple covariates, the hazard ratios (95% confidence intervals) for incident MetS for the second, the third, and the fourth quartile to the first quartile of serum UA levels were 1.09 (0.92-1.29), 1.22 (1.04-1.44), and 1.48 (1.26-1.73), respectively (p for trend <0.001). These associations were also significant in the clinically relevant subgroup analyses. CONCLUSIONS: Elevated serum UA levels were independently associated with future development of MetS in Korean men during the 5-year follow-up period.

Paraduodenal hernias are a rare congenital malformation, but they are the most common internal hernias. They develop secondary to a failure in midgut rotation, which may lead to small bowel obstruction or other clinical manifestations. The authors recently experienced a case of a left paraduodenal hernia presenting with unusual symptoms of left flank pain and vomiting.

OBJECTIVE: To examine the relationship between hypertension prevalence and the four commonest anthropometric measurements for obesity(body mass index(BMI), wasit-hip ratio(WHR), waist circumference(WC) and body fat in Korean adults. METHODS: We studied the cross-sectional association of the anthropometric indices and blood pressure in 1,197 individuals( who were participants in the population-based cohort study). Hypertension was defined as blood pressure 160/95 mmHg or current use of antihypertensive medication. Informations on life-style factors were obtained from personal interview. RESULTS: There were close associations between BMI, WHR and WC with blood pressure in both men and women. After age adjustment, BMI and WC showed significantly positive correlation with systolic and diastolic blood pressure levels in both men and women. Odds ratio(ORs) of being hypertensive were estimated comparing the highest to the lowest quantile, adjusting for age, smoking status, alcohol intake levels, education attainment. The simultaneously adjusted ORs of being hypertensive, comparing the highest vs the lowest categories, was for BMI 2.0(95% confidence interval(CI)=0.9-3.2) in men and 3.2 (95% CI=1.7-6.1) in women, for WC 2.1(95% CI=1.0-4.4) in men and 3.1(95% CI=1.6-5.9) in women, for fat(%) 4.2(95% CI=1.9-9.5) in men and 2.1(95% CI=1.2-3.6) in women. CONCLUSION: In addition to measures of overall obesity(BMI) as well as central obesity(WHR, WC), body fat(%) was independently associated with prevalence of hypertension. Among obesity indices, body fat was the most predictor variable in hypertensive state in male and BMI was in female.

PURPOSE: This study was designed to investigate the fitness of adjustable dental impression trays on the Chinese and the Japanese. MATERIAL AND METHODS: Initial design of the adjustable dental trays was developed from the results of the dental arch size of Korean adults. This design was applied to the CAD-CAM process in order to create tray model samples. Simple silicon-base molds were then replicated based on these sample models. Polyurethane injection into the silicon-base molds completed the process of creating a large number of test products. 60 Chinese dental students (male:30, female:30) from the Shanghai Second Medical University and 60 Japanese alumni from the Kumamoto high school (male:30, female:30) were selected for taking irreversible hydrocolloid impression with these trays. The width and length of the impression body were measured on several measuring points by Vernier caliper. The results were analyzed statistically to evaluate the fitness of the trays. RESULTS: 1. Uniform impression material thickness was achieved on the Chinese and Japanese by controlling the width of the tray using stops and beveled guides. The material thickness was generally within the range of 3 mm to 6 mm. 2. In the maxillary tray of the Chinese, average thickness of the impression material of the labial vestibule of the incisal teeth was 6.2 mm, the canine was 5.9 mm and the midpalatal part 10.5 mm and the posterior palatal part 9.7 mm. These were relatively large values. 3. In the mandibular tray of the Chinese, average length of the impression material of the lingual vestibule of first, second premolar contact point was 8.9 mm, the incisal teeth was 7.8 mm and thickness of the labial part of canine was 6.8 mm and premolars 7.0 mm. These were relatively large values. 4. In the maxillary tray of the Japanese, average thickness of the impression material of the labial vestibule of the incisal teeth was 7.4 mm, the canine was 7.7 mm and the midpalatal part 9.1 mm. These were relatively large values. 5. In the mandibular tray of the Japanese, average thickness of the impression material of the labial vestibule of first, second premolar contact point was 8.4 mm, and thickness of the labial part of canine was 7.4 mm. These were relatively large values. CONCLUSION: This adjustable dental tray shows good accuracy to Korean because it was designed by the analysis of the dental arch size of Korean adult model. With this result, it can be applied to Chinese and Japanese, we can take more easy and accurate dental impressions.

Although non-alcoholic fatty liver disease has been reported as a cardiometabolic risk factor, the effect of non-alcoholic fatty liver is yet to be clarified on abdominal obesity. Therefore, this study was conducted to investigate the longitudinal relationship of non-alcoholic fatty liver on the development of abdominal obesity. The study participants were composed of 11,212 Korean men without abdominal obesity. They were followed up from 2005 to 2010 to be monitored for the development of abdominal obesity according to their degree of non-alcoholic fatty liver disease (normal, mild, and moderate to severe). Cox-proportional hazard model was used to calculate the hazard ratios for abdominal obesity according to the degree of non-alcoholic fatty liver disease. While the average incidence was 15.5%, the incidence of abdominal obesity increased according to the degree of non-alcoholic fatty liver (normal: 11.6%, mild: 25.2%, moderate to severe: 41.0%, P < 0.001). Multivariable-adjusted hazard ratios for abdominal obesity independently increased proportionally to the degree of NAFLD (mild [1.07; 0.94-1.23], moderate to severe [1.58; 1.11-2.26], P for trend < 0.001). The risk of abdominal obesity increased proportionally to the degree of non-alcoholic fatty liver disease. This finding guarantees further studies to reveal the incidental relationship of abdominal obesity with non-alcoholic fatty liver disease.

PURPOSE: Lymph node metastasis is one of the most important prognostic factors in breast cancer. Survival of patients with axillary node positive breast cancer is worse than that of patients with axillary lymph node negative breast cancer. Recently, some authors suggest that axillary dissection may be avoidable if sentinel nodes of the breast cancer do not harbour metastasis. However, 15-20 % of patients with lymph node negative breast cancer recurs within 10 years. Micrometastasis, which was missed or not detected in routine histologic examination, is thought to be one of the reasons for recurrence of axillary node negative breast cancer patients. METHODS: We investigated the frequency of micrometastasis and any clinical significance of micrometastasis in the breast cancer by immunohistochemical staining with anti-cytokeratin antibody from July, 1996 to November, 1990. 70 patients who underwent curative resection for axillary node negative breast cancer were studied retrospectively. We used paraffin blocks of lymph nodes which did not show metastasis by conventional pathological examination. After preparation of tissue blocks with a serial sectioning technique, specimens were stained by an immunohistochemical method using anti-cytokeratin antibody. Hematoxylin-eosin stainings were also repeated. We define metastasis less than 2mm as a micrometastasis. RESULTS: The results showed that micrometastasis were found in 8 of 70 cases(11.4%). There was a significant relationship between the micrometastasis and tumor size. With median follow-up of 20 months, we found 3 recurrences in 70 patients. : 2 recurrences(3.2%) in the 62 axillary node negative breast cancer patients and 1 recurrences(12.5%) in 8 micrometastasis patients. CONCLUSIONSThe results showed that micrometastasis of lymph node in breast cancer might increase the rick for development of breast cancer recurrence. But, there was no significant relationship between the micrometastasis and recurrence of breast cancer because of small numbers of recurrences and relatively short follow-up period. Long tern follow-up will be needed for further evaluation.

A 49-year-old male patient was admitted with chief complaint of hemoptysis. Preoperative chest PA and CT scan revealed air-filled large cavitary lesion at the right upper lobe with typical meniscus sign. Serum anti-fungus antibody for Aspergillus was positive and he was diagnosed as aspergilloma. We planned RULobectomy but it was impossible due to severe pleural adhesion in apex and mediastinal pleura. Therefore, we performed a cavernostomy and serratus anterior muscle flap transposition in one stage. The patient recovered without complication and was followed up for 8 months without recurrence of hemoptysis.
