Since 1980, 18 patients(12 males, 6 females) with intractable perineal and perianal pain caused by uncontrolled malignant neoplastic disease, were surgically treated with sacral rhizotomy. Patients ranged in age from 33 to 74 years ; the duration of symptoms ranged from 2 months to 17 months. The primary site of the malignancies were as follows : prostate cancer(3 cases), cervix cancer(5), colorectal cancer(10). All patients underwent preoperative psychological test, drug assessment, cystometry and trial block. The present criteria for selection were : 1) All patients should have uncontrolled malignant disease with metastasis. 2) The pain should be limited to the perineal or the perianal region. 3) The pain should be severe and refractory to medical and psychological management. 4) The pain should be of least 3 months. 5) Estimated life expectancy should be at least 3 months. 6) All patients should have had a previous colostomy. 7) The operative modification should be made according to the urinary disturbance. If there is no voluntary urination, the operation should include both S2 roots ; but, if the bladder is still functioning normally, the S2 root should be preserved in the least painful side. Postoperative results of pain control were no pain in 14 patients(78%), good in three(16%), and poor in one(6%). After reviewing the results, the authors believe that if the patients are selected properly, according to the criteria outlined, sacral rhizotomy is worthwhile, simple and relatively successful method of treating intractable perineal and perianal cancer pain.

Peutz-Jeghers syndrome is a rare autosomal dominant disorder defined by harmatomatous polyps of the gastrointestinal tracts and the occurrence of melanin spots on the lips(oral mucosa), hands and feet. This syndrome is associated with a variety of gastrointestinal and extraintestinal neoplasms, both benign and malignant. A 28-year old male was admitted to our hospital with abdominal pain and nausea for two months. He had melanin spots involving his lips, buccal mucosa, hands and feet. A small bowel series showed luminal obstruction at the forth portion of the duodenum. And abdominal CT scan showed target-like mass suggesting intussusception on the small bowel. On laparotomy, there was an annular constricting mass adherent to retroperitoneum with metastasis to preaortic lymph nodes. Palliative duodeno-jejunostomy was performed. The histologic finding disclosed signet-ring cell type adenocarcinoma.

OBJECTIVES: Catechol-O-methyltransferase (COMT) plays an important role in metabolizing catecholamines, including dopamine. Also, several single-nucleotide polymorphisms (SNPs) of the COMT gene are associated with schizophrenia. Therefore, this study aimed to find the association between COMT gene SNPs and schizophrenia in Koreans. METHODS: Participants were 366 schizophrenia patients and 359 normal controls. To identify the SNPs, we performed genetic analyses in 4 SNP regions, via SNP-ITTM assays. We compared allele, genotype, and haplotype frequencies between the two groups. Moreover, we built subgroups, based on onset age, and compared individual allele and genotype frequencies among these subgroups. RESULTS: In female patients, genotype frequencies showed a significant difference in rs2020917 among the 4 SNPs (p=0.0224), but haplotype frequencies showed no such difference among the 4 SNPs between patients and controls. We noted a significant difference in rs1544325 allele frequencies according to onset age. Also, in female patients, rs1544325 allele and genotype frequencies varied significantly according to onset age. CONCLUSION: This study found no genetic association between the COMT gene's 4 SNPs and schizophrenia in Koreans. However, our findings suggest genetic components for sex-specificity and onset age in Korean schizophrenics.

The methylglyoxal (MGO) trapping constituents from Malus baccata L. were investigated using incubation of MGO and crude extract under physiological conditions followed by HPLC analysis. The peak areas of MGO trapping compounds decreased, and their chemical structures were identified by HPLC-ESI/MS. Sieboldin was identified as a major active molecule representing MGO-trapping activity of the crude extract. After reaction of sieboldin and MGO, remaining MGO was calculated by microplate assay method using imine (Schiff base) formation of 2,4-dinitrophenylhydrazine (DNPH) and aldehyde group. After 4 h incubation, sieboldin trapped over 43.8% MGO at a concentration of 0.33 mM and showed MGO scavenging activity with an RC 50 value of 0.88 mM for the incubation of 30 min under physiological conditions. It was also confirmed that sieboldin inhibited the production of advanced glycation end products (AGE) produced by bovine serum albumins (BSA)/MGO. Additionally, MGO trapping mechanism of sieboldin was more specifically identified by 1 H-, 13 C-, 2D NMR and, confirm to be attached to the position of C-3' (or 5').

OBJECTIVES: Common genetic SNPs in two genes, encoding catechol-O-methyltransferase (COMT) and methylenetetrahydrofolate reductase (MTHFR), which are interconnected with COMT gene regulation, have been reported to contribute to schizophrenia risk. In this study, we evaluated the association between functional polymorphisms in COMT and MTHFR and schizophrenia risk with a case-control study in a Korean population. METHODS: We performed a case-control study by genotyping analysis using 360 cases and 348 controls in Korean subjects to determine the association between functional polymorphisms in COMT and MTHFR and schizophrenia risk. RESULTS: Four functional SNPs in COMT (Val158Met and rs165599) and MTHFR (C677T and A1298C) were genotyped by primer extension assay. None of the genotype distributions for the four SNPs was significantly different between cases and controls. Stratified analysis did not show any significant gender difference for any polymorphism. In addition, we found no evidence of a gene-gene interaction in the analysis of combined genotypes. CONCLUSION: Our results suggest no significant association between the selected functional polymorphisms of COMT or MTHFR in Korean schizophrenia subjects. However, further studies are required to confirm our findings in a larger number of subjects.

OBJECTIVES: This research aimed to know the actual condition and problems of medical information protection at a workplace with the target of industrial health care managers of small and medium-sized enterprises. METHODS: A self-administered questionnaire was given to industrial health-care managers of 216 enterprises from March 15 to May 17, 2010. The questionnaire was produced by referring to the Act on Personal Information Protection of Public Institutions, etc. This research evaluated agreement of cognition and practice according to 10 items of medical information protection using kappa and cross-analysis of significant factors between cognition and practice of medical information protection and general characteristics. RESULTS: Cognition about medical information protection appeared to be 85.4-97.1% and its practice appeared to be 44.1-95.3%, so practice was lower than cognition. In addition, the agreement of cognition and practice appeared significantly low (kappa 0.082-0.387). The practice of medical information protection tended to be lower when the managers were older and held a higher job title. Health examination results were being delivered only to workers except for an employer (94.2%), but there were many industrial health-care managers who felt discomfort about their work in group occupational health-care systems (58.1%). CONCLUSIONS: The practice of protecting medical information by industrial health-care managers was clearly lower than the cognition. Therefore, introduction of educational programs about personal information protection and provision of an independent place for group occupational health care service is urgent. In addition, in order to use the health examination results conveniently in group occupational health services, an institutional complement is necessary.

Foreign body ingestion is a relatively uncommon, but potentially serious condition. Most of gastrointestinal foreign bodies pass spontaneously. But, large objectives are usually lodged in the stomach and cause perforation, bleeding, and obstruction. Therefore, prompt retrieval of lodged foreign bodies are necessary before complications develop. Particularly, in the case of long metallic spoon, there have been no cases of spontaneous passage reported. Therefore, prompt retrieval of a metallic spoon are necessary. A 28-year-old woman with schizophrenia who ingested a long spoon for suicidal attempt was referred to our hospital. Simple abdomen showed a 18 cm sized long, metallic spoon with saw-toothed end placed in the stomach. We removed a spoon by an endoscopic technique and an extraction maneuver using a guidewire and a Magill forceps.

OBJECTIVES: The objective of this study was to identify the relationship between fish consumption and blood mercury levels in a sample of adult Koreans. METHODS: The study subjects were 299 residents of Busan (male: 65, female: 234) and 185 residents of Namhae (male: 69, female: 116), South Korea. Demographic characteristics, current smoking, current drinking, fish consumption per week, past history of amalgam treatment, and residential district were recorded by trained interviewers in June and July, 2009. We considered a portion of fish to be equivalent to 70 gm weight, and calculated amounts of fish consumed per week. Using chi-square tests, t-tests, ANOVA, and multiple linear regression analysis, we estimated the relationships between blood mercury levels and amount of fish consumed per week and other factors. RESULTS: The mean blood mercury level of our subjects was 6.61 microgram/L, higher than the criterion defined by the United States Environmental Protection Agency (EPA) (5.8 microgram/L). In multiple linear regression analysis, residential district and amount of fish consumed per week were associated with blood mercury levels. However, marital status, current drinking, and gender, and age were not associated with blood mercury levels. CONCLUSIONS: In conclusion, we suggest the implementation of systematic and periodic population-based studies to decrease the risks of mercury poisoning among South Koreans who consume fish as a regular part of the diet.
