BACKGROUND: Propioriacterium acnes plays an importantol in the development of inflammatory acne, and inflarnmatory lesions are improved by oralnc topical antibiotics. But as Pacnes frequently develop resistance to antibiotics in patients neing long term systemic antibiotic therapy, the theravuti effects diminish, and eventually thay fails. OBJECTIVE: The purpose of this study is to evaluate theerral susceptability of P. acnes to antibiotics and the difference in the MIC depending on the of oral and/or topical antibiotics, therapeutic effects and disease duration in patients with acie ulgaris. METHODS: We used twenty six strains of P. acnes which were obtained from patients with acne and performcd suseptibility testing for antibiotics usir the E test procedure. RESULTS: 1. The growth of P. acnes was completely inhibited by e ythromycin and chloramphenicol at concentrations of 0.023ug/ml and 0.064ug/ml, respectively cefoxitin at 0.094ug/ml, and by tetracycline and clindarnycin at 0.190 ug/ml. 2. P. acnes was mot susceptible to erythromycin, and olwed by chloramphenicol, cefoxitin, tetracycline, clindamycin in order of decreasing susceptibilit . 3. There were no significant differences in the MIC in reat in to previous antibiotic treatment. 4. For tetracycline, The MIC was significantly lower(p<0.01) in patients who improved after treatment. 5, For tetracycline and chloramphenicol, the MIC was grficantly lower(p<0.05) in patients with less than 2 years disease duration. CONCLUSION: The susptibility of antibiotics for P. acneias highest in erythromycin. There were no significant differences in the MIC in relation to prvious antibiotic treatment, and for some antibiotics the suseptibility was low in patients who dill not show clinical improvement or who had long disease duration.

BACKGROUND: Tandem duplication of chromosome 17p11.2-p12 including peripheral myelin protein 22 (PMP22) gene is the most frequent cause of Charcot-Marie-Tooth 1A (CMT1A). Patients carrying one extra copy of PMP22 develop CMT1A, whereas the deletion of the 17p11.2-p12 region causes hereditary neuropathy with the liability to pressure palsies (HNPP). In the present study, we established the genotyping methods of 6 microsatellite markers (D17S921, D17S9B, D17S9A, D17S4A, D17S918 and D17S122) within the 17p11.2-p12 regions by the hexaplex PCR for the genetic diagnosis of CMT1A duplication and HNPP deletion. METHODS: We established polymorphic behavior and genotyping methods of 6 microsatellite markers (D17S921, D17S9B, D17S9A, D17S4A, D17S918 and D17S122) within the duplication region. The 6 markers were amplified by hexaplex PCR reaction and analyzed by an automatic sequencing analyzer and genotyper program. RESULTS: The genotype distributions of all markers were not significantly deviated from the Hardy-Weinberg equilibrium (P>or=0.05). When comparing the control group and CMT1A, HNPP patients group by the distribution of allele, there is no significant difference in the 5 locus except in the 1 locus (D17S921) among HNPP patients. The specificity was more than 99.9%. The sensitivity of each CMT1 and HNPP was 56.3% (40/71 pedigrees) and 72.1% (31/43 HNPP pedigrees), respectively. CONCLUSIONS: The error rate for the system may be less than 0.001. According to this study, it is possible to have rapid and exact genetic diagnosis of both CMT1A and HNPP, which may be helpful for the development of personalized therapy according to genetic defects.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) continues to be a major cause of nosocomial infection and a molecular typing is necessary for proper epidemiologic investigations of sources and moles of spread in an outbreak. An nosocomial outbreak of MRSA in a neonatal intensive care unit at Ewha Womans University Mokdong Hospital was suspected. To investigate the clonality of isolates and control the spread of nosocomial outbreak, we performed plasmid restriction analysis of MRSA isolates from patients and medical staffs. METHODS: We studied 7 MRSA strains (umbilicus 4, blood 1, urine 1 and pus 1) from patients in a neonatal intensive care unit and the MRSA strains from nares and hands surveillance cultures of 26 medical staffs (4 medical doctors and 22 nurses). All MRSA strains were tested for antimicrobial susceptibility and plasmic analysis after EcoRI restriction. We analyzed the plasmid patterns of MRSA isolated from patients and compared with those from medical staffs. RESULTS: Ten MRSA strains (from 7 nares and 3 hands) were isolated from surveillance cultures of 26 medical staffs. Seven out of 10 MRSA strains from medical staffs revealed identical pattern of antibiogram which was the same pattern in all 7 MRSA strains from seven patients. Plasmid restriction patterns were classified 6 groups from A to F showing 2-10 bands. Six out of 7 MRSA strains from the patients showed group A(A1 5, A31) and 5 out of 10 MRSA strains from the medical staffs showed group A(A1 1, A21, A32, A41) and remainders showed different plasmid restriction analysis patterns. CONCLUSIONS: These results suggest that plasmid restriction analysis is a rapid, inexpensive, and good discriminating molecular typing of MRSA outbreak and is useful for the epidemiologic investigation of MRSA outbreaks in the clinical laboratory.

An unusual case of glroependymal cyst involving the lateral ventricle, 3rd ventricle, cerebellopontine angle cistern and prepontine cistern, simultaneously, is reported. The glroependymal cyst is benign developmental cyst that mainly occurs in the cerebrospinal axis in relation to ventricle, but occasionally occurs in relation to extraventricular system, such as subarachnoid space, brain stem and cerebral parenchyme. The histological characteristics of ependymal cyst wall are ependyma-like epithelium and neuroglial tissue.

In a small island community with a population of less than 100 residents, nine persons died and five experienced severe illness during the period from November 1986 to May 1988. Their initial symptoms were sore throat and fever. Renal failure and hepatitis developed which one week after the onset. Oral mucosal ulcer developed in some cases. After one week, progressive respiratory failure and dyspnea developed evidently and severe respiratory distress and hypoxia preceded those fatal cases. Chest X-ray findings revealed bilateral diffuse multiple cystic lesion with occasional multiple large emphysematous bullae. Based on these features paraquat poisoning was diagnosed and route of poisoning was investigated. In three sources of drinking water, trace amount of paraquat was detected in November 1988, six months after the incidence of recent fatal case. In November 1988, soybean sauces and soybean pastes from 12 households were found contaminated with high concentration of paraquat, the cause of this mass poisoning has been suggested.

The authors present a case of oligodendroglioma in the 4th ventricle which is extremely rare in occurrence. The patient is 11 year-old male whose complaints were severe headache and vomiting. In the brain computes tomogram, hyperdense mass seated in the 4th ventricle with marked hydrocephalus. The patient had operation for removal of the tumor. In the operating field, there are no relation of the choroid plexus and specific vesselas but the tumor attached firmly on the floor of the 4th ventricle. The tumor was removed totally. The pathologic specimens were verified oligodendroglioma.

Vascular lesions involving the upper extremities have been treated by different route of upper thoracic sympathectomy with varying success. More recently, the anatomic and physiologic interest for autonomic nervous system has been progressively mounted but the surgical attack has plateau. It may be worthy for academic interest and clinical practice to estimate and to compare with the different surgical method. This paper concerns the treatment of a case suffering from atherosclerotic occlusion whom were treated by upper thoracic sympathetic ganglionectomy through the transaxillary transpleural route. This operation seems to be simpler than other surgical methods with lower morbidity, fewer complication and satisfying results.
