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.

Of the many potential source of free radial generation, the enzyme xanthine oxidase has been shown to be important in ischemia in non-cerebral tissues. Oxygen-derived free radicals have been implicated in various pathological conditions including ischemia. Xanthine oxidase serve as a source of oxidizing agents such as superoxide radical and hydrogen peroxide. It is investigated that the effect of a specific xanthine oxidase inhibitor, allopurinol, on infarct size in a model of continuous partial cerebral ischemia in rats. Infarct volume was measured by triphenyl tetrazolium chloride staining of brains removed 24 hours after middle cerebral arterial occlusion. Cortical tissue was more effectively protected than basal tissue, especially in allopurinol pretreated group. On histological examinations, hemispheric swelling, PMN cell infiltration and endothelial damage were noted irrespective of allopurinol treatment. It was speculated that free radicals are important in infarction secondary to partial continuous cerebral ischemia and that xanthine oxidase may by the primary source of these radicals.

The intracranial arachnoid cysts are benign lesions in nature which thin walled cysts lying in relation to or enclosed by the subarachnoid space, filled with clear fluid. They may be due to developmental defects of the brain or meninges and secondary to inflammation, vascular occlusion or trauma but etiology of a large percentage is not well understood. In general, locations are near primary fissure and cisterns of the cerebral cortex and cerebellum. The clinical features and courses are unusual. Preoperative diagnosis is unlikely to be made but treatment is followed by good result. We had experienced two cases of intracranial arachnoid cysts which occurs in middle cranial fossa, and cerebral hemisphere. Pathologic diagnosis are arachnoid cysts.

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.

We have reported a case of acute spontaneous spinal epidural hematoma in a male patient aged 79-year-old who had suddenly felt a strong pain in the right buttock and lower abdomen. Shortly after he noticed weakness in his legs and two hours later he was completely paraplegic. Operation was undertaken 13 hours after the onset of the illness. A laminectomy was mode from T11 to L1 and a massive epidural hematoma removed mainly from the right posterolateral aspect of the cord.
