1.Isolated Lateral Ventricle after V-P Shunt.
Journal of Korean Neurosurgical Society 1991;20(4):253-256
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.

Authors experienced the lumboperitoneal shunt in 13 patients. There were 8 communicating hydrocephaluses, 2 benign intracranial hypertensions, 2 cerebrospinal fluid fistulas and 1 postcraniectomy bulging. Lumboperitoneal shunt was thought to be a very simple extracranial procedure which reduce the complications from ventriculoperitoneal shunt such as subdural fluid collection, subdural hematoma, slit ventricle syndrome and conversion from communicating hydrocephalus to non-communicating hydrocephalus. The efficacy of this procedure was documented and literatures were reviewed.

OBJECTIVE: This study is designed to investigate the association of tumorigenesis with DNA repair gene, N-methylpurine-DNA-glycosylase(MPG) in astrocytic tumors. METHODS: MPG mRNA expression and localization in the 30 astrocytic tumors and 7 tumor-adjacent brain tissues was examined by reverse transcriptase-polymerase chain reaction(RT-PCR) and RNA in situ hybridization. Expression and intracellular localization of MPG protein was determined by immunohistochemistry. Statistical analysis was performed by ANOVA with a p value<0.05 considered statistically significant. RESULTS: MPG mRNA expression in RT-PCR was significantly higher in grade IV tumor tissues than in brain tissues adjacent to tumor or in grade II-III astrocytic tumor tissues(p<0.05). MPG mRNA in in situ hybridization was detected both in brain tissues adjacent to tumor and in astrocytic tumor tissues, regardless of the tumor grades. However, MPG protein localization in immunohistochemical study was detected only in the nucleus of all tumor tissues. In brain tissues adjacent to tumor, immunohistochemical study for MPG was not stained both in the nucleus and in cytoplasm. CONCLUSION: These results suggest MPG's role in human astrocytic tumors and raise the possibility that the increased mRNA level and intracellular localization could be associated with astrocytic tumorigenesis. Further studies about control of MPG gene expression in astrocytic tumors are warranted.

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.
