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.

A 35-year-old male patient with hydrocephalus due to spontaneous subarachnoid hemorrhage secondary to brain tumor were treated with ventriculo-peritoneal shunt. Subsequently an unusual liver abscess developed at right lobe of liver which was drained successfully through the percutaneous puncture method. The liver abscess and ventriculitis was controlled with systemic, intrathecal and intraventricular antibiotics administrations. The authors have never seen a report of liver abscess after the ventriculoperitoneal shunt. The computed tomographic findings, managements of infection and a review of the literature is presented.

BACKGROUND: Plasma cell neoplasm is diagnosed by performing bone marrow examination, serum- and urine-protein electrophoresis, and quantification of free light chains of immunoglobulins. We characterized and quantified monoclonal proteins typical of different diagnosed conditions to determine the best screening test(s). METHODS: We retrospectively reviewed diagnosis of and the characteristics of monoclonal proteins from 113 patients with monoclonal gammopathy. Monoclonal proteins were detected by agarose-gel electrophoresis and capillary electrophoresis, and if the results were ambiguous, they were confirmed by immunofixation electrophoresis. Free light chains were measured using nephelometry. RESULTS: The concentrations of monoclonal proteins in 113 patients with different conditions were as follows: multiple myeloma (MM) (67%), 2.66 (0.87-9.48) g/dL; monoclonal gammopathy of undetermined significance (MGUS) (26%), 0.62 (0.08-2.95) g/dL; lymphoma (3%), 3.65 (1.59-6.54) g/dL; Waldenstrom's macroglobulinemia (2%), 1.99 (1.08-2.90) g/dL; amyloidosis (2%), 0.61 g/dL; and POEMS syndrome (1%), 0.99 g/dL. There was a significant difference in the concentration and kappa/lambda ratio (which was based on the immunetype of the monoclonal proteins) of the monoclonal proteins in patients with MM and MGUS (P<0.001 and P=0.004, respectively). The diagnostic sensitivity of serum-protein electrophoresis, free-light-chain assay, and bone marrow analysis was 87.6%, 84.1%, and 84.5%, respectively. The sensitivity of a combination of 2 or 3 of these tests was higher at 100%. CONCLUSIONS: A combination of protein electrophoresis with immunotyping and serum free-light-chain assay may be the best screening method for detecting monoclonal proteins since its non-invasiveness.

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.
