Vibrio parahaemolyticus is a gram-negative halophilic organism commonly associated with outbreaks of acute gastroenteritis which also sometimes causes serious wound infection. It is an uncommon cause of bacteremia. We have experienced a case of bacteremia due to Vibrio parahaemolyticus in a 59-year old man who initially presented with edema and dyspnea. He was diagnosed as liver cirrhosis, gastric cancer, and hepatoma. On hospital day 13, Vibrio parahaemolyticus was isolated from blood culture. The isolate showed typical cultural and biochemical characteristics such as salt tolerance and did not ferment lactose. The isolate was intermediate to ampicillin but susceptible to other agents.

BACKGROUND: Recent data suggest that the colonization rate of group B streptococci(GBS) in pregnant women and the incidence of neonatal infections by GBS is increasing trend in Korea, but the antimicrobial susceptibilities and serotypes in pregnant women have not been reported in Korea. So, we studied to define the antimicrobial susceptibility patterns and frequency of serotypes of GBS in pregnant women. METHODS: The susceptibility and serotyping of 60 GBS isolates from 27 pregnant women and four isolates from their two neonates were tested by an agar dilution method and agglutination test, respectively. The typing sera used in this study were Ia, Ib, II, III, IV, and V. RESULTS: Minimal inhibitory concentration range of 60 GBS from pregnant women were penicillin G 0.015-0.12 microgram/ml, vancomycin 0.5-2 microgram/ml, clindamycin 0.015-4.0 microgram/ml, chloramphenicol 2-4 microgram/ml, erythromycin 0.015-2 microgram/ml, tetracycline 0.5-256 microgram/ml, cephalothin 0.12-0.25 microgram/ml, ceftriaxone 0.03-0.12 microgram/ml, respectively. The resistance rate of GBS were 6.7% to clindamycin, 0% to erythromycin, and 98.3% to tetracycline. Most of GBS serotypes from pregnant women in decreasing order were Ib(48.3%), Ia(24.1%), III(20.7%). CONCLUSION: All GBS strains isolated from pregnant women are highly susceptible to commonly used antimicrobial agents with the exception of tetracycline. The low prevalence of severe neonatal GBS infections in Korea is not due to the absence of serotype III, but probably due to a low genital carriage rate of GBS by pregnant women.

BACKGROUND: Group B streptococci (GBS) are the most common cause of sepsis and meningitis in newborns in the United States and Europe, and maternal colonization rate of GBS is the most important factor of group B streptococcal neonatal infections. But, in Korea, studies on the maternal colonization rate of GBS are rare due to low incidence of neonatal group B streptococcal infections, particularly, data on colonization rate of GBS during first trimester is nearly absent. The aim of this study was to establish the rates of maternal carriage of GBS and the distribution of GBS serotypes in first trimester of pregnancy. METHODS: During the period of June to December 1997, we studied women attending private clinic. A total of 309 women in first trimester were enrolled in the study. Cotton swab specimens from vagina and cervix were placed to new Granada tube medium. The new Granada tube medium with specimen swab was incubated in 5% CO2 atmosphere at 35degreesC. For the identification of GBS, the colonies showing orange color on new Granada tube medium were tested with Streptex group B Streptococcus reagent (Wellcome Diagnostics, UK). Serotyping was done by Hemolytic Streptococcus Group B Typing Sera (Denka Seiken, Japan). The typing sera used in this study were Ia, Ib, II, III, IV, and V. RESULTS: Of the pregnant women in first trimester, 2.3% (7/309) were colonized with GBS, and all seven women who colonized GBS were positive in vagina and cervix at the same time. Frequency of serotype III and Ib were 71.4% (5/7) and 29.6% (2/7), respectively. Serotypes Ia, II, VI, and V were absent. CONCLUSIONS: Maternal carriage rate of GBS in first trimester of pregnancy was 2.3%, and serotype III was the most common serotype. Serotypes Ia, II, VI, and V were absent.

Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.

BACKGROUND: The erythromycin-resistance rate and phenotype distribution of Streptococcus propenes are quite different by geographical variation and study period. The aim of the present study was to determine the evolution of resistance to erythromycin and the frequency of erythromycin resistance phenotype of S. pyogenes isolated from Wonju Christian Hospital. METHODS: The minimal inhibitory concentrations (MICs) of erythromycin and clindamycin for 94 S. pyogenes isolated from clinical specimens between 1990 to 1998 were investigated. Double disk test of erythromycin (78microgram) and clindamycin (25microgram) were performed for 15 isolates of erythromycin resistant S. pyogenes to evaluate the erythromycin resistance phenotype. RESULTS: The resistance rates of 94 isolates of S. pyogenes were 16%(15/94) to erythromycin and 4%(4/94) to clindamycin. The frequency of erythromycin resistance phenotype in decreasing order were M phenotype (47%), inducible resistance phenotype (40%), and constitutive resistance phenotype (13%). Erythromycin-resistant S. pyogenes did not exist until 1993, but was isolated since 1994, and ranged from 14.0% to 24.0% during the period of 1994-1998. CONCLUSIONS: Our finding documents the emergence of high resistance rates to erythromycin in S. pyogenes at Wonju area since 1994. The M phenotype (47%) and inducible resistance phenotype (40%) account for the majority of erythromycin-resistant S. pyogenes.

Clinical characteristics of papular-purpuric gloves and socks syndrome consist of a purpuric erythema affecting the hands and feet in a gloves and stocking distribution. It is sometimes associated with fever and oral lesions. The disease is self-limiting and resolves within 1 to 2 weeks. Serological studies have shown that there is an association with parvovirus B19 infection in most patients affected by this syndrome. We report a case of gloves and socks syndrome in a 21-year-old female. She had a 4-day history of papular-purpuric eruptions of the hands and feet in a gloves-and-socks distribution. She also complained of fever(up to 39C) during the first 2 or 3 days of clinical onset. The oral mucosa was normal and there were no palpable lymph nodes. Laboratory and histopathological findings were non-specific. However, human parvovirus B19 DNA was detected in the serum by a polymerase chain reaction. Systemic manifestations were transient and disappeared within a few days, whereas the skin lesions resolved gradually over a period of 2 weeks.

Spindle cell lipoma was first described in 1975 by Enzinger and Harvey as a variant of lipomas. Histopathological findings show the lipomatous tissue to be replaced by a mixture of uniform spindle cells and mature fat cells closely associated with a mucoid matrix and a varying number of collagen fibers. Immunohistochemical staining is reported to give assistance in the differential diagnosis af spindle cell lipoma from other fibrous or neural tumors. Also, it can be used to investigate the origin of the spindle cells. We report a case of spindle cell lipoma in a 41-year-old female. She had a solitary, normal skin colored, bean sized, subcutaneous mass on the forearm. Most of the spindle cells were strongly positive for vimentin, CD34 and NSE, but negative for actin, factor VIII, S-100 protein and neuro- filaments. The tumor was excised. No recurrence was recognized in a 10 month follow up period.
