We evaluated the muscle fiber characteristics, the mean proportion of muscle fiber types and its range of individual difference in human vertebral muscle. Muscle samples used were from subjects who had a relatively brief history of spinal dysfunction such as compression fracture, disc hernia etc., and obtained from precisely defined superficial and deep sites on both sides of the vertebral column. In particular, samples were collected from three different levels of the column and flash-frozen sections of biopsied adult vertebral muscles were stained for H–E, trichrome, PAS, regular and reversed myosin ATPase, and SDH. Discrimination of muscle fiber types in H–E and trichrome stained sections was not evident. Three types of muscle fibers were, however, evident in PAS-stained sections according to the degree of positivity in observed vertebral muscles. The mean proportion of musele fiber types was different in regular and reversed myosin ATPase, and SDH stains and the majority of fiber types in human vertebral muscles was type I in three different levels of vertebral clumn. There was a decreasing tendency in percentage of type I fibers at both superficial and deep levels as the vertebral column descended. The size of muscle fibers was relatively larger in deep levels than in superficial levels of vertebral muscles. The human vertebral muscle showed moderately individual and regional differences in the mean size of fiber types. The evaluation for the combination patterns of various enzyme histochemical activities showed that the common musele fiber types(type I, II A and II B) were moderately reduced in the mean proportions and unusual rare muscle fiber types increased in number. And the decreasing tendency in the mean proportion of type as the vertebral column descended was not evident in the combination patterns of histochemical activities

Diffuse neonatal hemangiomatosis is an uncommon disease that is characteristed by a diffuse nature of the lesions, and distinguished form a single or few, or superficial or deep, capillary, cavernous, or mixed hemangiomas occuring in early or adult life. We report an autopsy case of multiple hemangiomatosis, which is associated with massive osteolysis of right humerus and arteriovenous fistulae in surrounding soft tissues. The patient is a 23 day old female infant and had a 2.0x1.5 cm sized cystic destructive bony lesion which was located in the proximal shaft of right humerus. Right arm was hypertrophied, compared to the normal looking left. There were multiple hemangiomas in right humerus, lung, cutaneous skeletal muscles and nerves. This case shares clinical characteristics of Gorham's disease.

PURPOSE: This study was undertaken to determine the incidence of chromosome 22q11 deletion in patients with infundibular ventricular septal defect(VSD). METHODS: Sixty-two children with infundibular VSD were included in this study from January 1999 to December 2000. Chromosome 22q11 deletion was confirmed by FISH, using LSI DiGeorge/VCFS region dual color probe(Vysis, USA). RESULTS: Thirty-two patients had conotruncal cardiac defects:tetralogy of Fallot (TOF) in 15; TOF with absent pulmonary valve in 1; VSD with pulmonary atresia in 7; truncus arteriosus in 3; double outlet right ventricle in 2; interrupted aortic arch in 2; transposition of the great arteries in 2. Thirty patients had isolated infundibular VSD without conotruncal cardiac defect:perimembranous infundibular VSD in 15; subarterial infundibular VSD in 9; muscular infundibular VSD in 6. Chromosome 22q11 deletion was observed in 8 patients(male 5, female 3):TOF 2; VSD with pulmonary atresia 4; truncus arteriosus 1; perimembranous infundibular VSD 1. All of the patients with chromosome 21q11 deletion showed typical facial appearance. Low incidence was found of chromosome 22q11 deletion in patients with infundibular VSD without conotruncal cardiac defect than in those with conotruncal cardiac defect(3.3% vs 21.9%). CONCLUSION: These data indicate that a small proportion of isolated infundibular VSD is pathogenetically related to deletion of chromosome region 22q11.

Vibrio vulnificus infection is one of the most fatal diseases in Korea. This study was undertaken to determine the cellular fatty acid (CFA) compositions of ninety-five clinical strains of V. vulnificus isolated from Korea during 1985-1995. We compared these results with the CFA profile of V. vulnificus in the Microbial Identification System (MIS) (CLIN library version 3.9; Microbial ID Inc., Newark, Del.), and also evaluated the MIS ability to identify V. vulnificus. Subgrouping of V. vulnificus by CFA analysis was performed and its results were compared with those of serotyping. Most of the CFAs in V. vulnificus strains were similar to the CFA profile of V. vulnificus in the MIS, but some distinctive differences were observed. First, means of two major CFAs, 16:0 and 16:1w7c, were 22.16% and 18.26% in this study, but 23.52% and 25.44% in the MIS respectively. Second, all isolates had 11:Oiso3OH, which was not present in the MIS. Eighty-five strains (89.5%) disclosed the first choice identification of V. vulnificus by the MIS, but only two strains (2.1%) were identified with SI values of 0.6. Remaining ten strains (10.5%) showed 'NO MATCH' results. Cluster analysis of CFA could separate V. vulnificus into nine subgroups, and predominant subgroups were subgroup VII (45 strains) and V (36 strains). There was heterogeny between subgroups by CFA and serotypes of V. vulnificus. The strains of 04 serotype which accounted for 80% (76/95) of the isolates were distributed into six different subgroups such as VII (40 strains), V (27 strains), III (4 strains), I (2 strains) and VI (1 strain). These showed that V. vulnificus strains isolated from Korea had different characteristics in the CFA composition in comparison with the MIS V. vulnificus library. Subgrouping by the CFA analysis might be a useful tool for the epidemiological study of V. vulnificus infection in Korea.

The patient was a 1-day-old female with full term normal vaginal delivery. Petechiae and purpura were noted on body surface at birth. She did not have mongoloid face and hand-foot deformity. The skin nodules were bluish to slate-grey in color, and observed on all body surfaces. Hepatosplenomegaly was also noticed. Peripheral blood smear showed marked leukocytosis (109,400/microliter), thrombocytopenia (16,000/microliter) and leukoerythroblastosis. VDRL and TORCH tests were negative. The bone marrow was replaced by leukemic lymphoblasts. The normal hematopoietic cells were depleted. The leukemic lymphoblasts expressed markers of mature B cell differentiation, negative for Sudan black B, peroxidase, and positive for PAS (en bloc pattern) stain. Skin biopsy specimen showed diffuse infiltration of the leukemic cells. The diagnosis was congenital mature B cell lymphoblastic leukemia. This patient died at 7 days after birth.

BACKGROUND: When central venous catheter (CVC) related sepsis is suspected based on clinical symptoms, removal of catheter is both diagnostic and therapeutic, but this approach leads to wastage of many sterile lines. Therefore, a reliable method to diagnose or exclude CVC sepsis without catheter removal is desirable. We performed differential quantitative blood cultures for the diagnosis of CVC related sepsis, in catheterized patients who had previous positive blood cultures. METHODS: Differential quantitative blood cultures were performed by collecting the blood specimens simultaneously via catheter and peripheral vein in 1.5 mL Isolator tubes (Wampole, USA). Sixty-three samples from 61 catheterized patients were taken and the colony counts from catheter blood samples were compared with those from peripheral samples. RESULTS: In 17 samples (27%), the colony counts from catheter blood samples were 5-fold higher than those from peripheral samples (the C/P ratio, > OR =5), suggesting CVC related sepsis; in 7 samples the C/P ratio was below 5, suggesting that sepsis was not CVC related. Of 35 samples (56%) in which no organisms were cultured, 2 samples were diagnosed as CVC related sepsis by the catheter tip culture. In 19 cases with proven CVC related sepsis, Candida spp. (n=8) and Gram-negative rods (n=7) were the predominant causative organisms and 16 cases (84%) were improved after catheter removal. CONCLUSIONS: This data show that quantitative blood culture method using Isolator may be very useful for diagnosing CVC related sepsis, especially in patients with positive blood cultures.
