Thirty cases of rhabdomyosarcoma in patients under the age of 15 years were reviewed retrospectively to find out characteristics of histologic subtypes related to prognosis. Histologic diagnosis were embryonal in 21(70%), alveolar in 7(23%) and mixed type in 2(7%). Cellular anaplasia was noted in 6 cases. Round to polygonal cells with abundant eosinophilic cytoplasmic rim or globules were most characteristic cytologic feature or rhabdomyosarcomas, being followed by myofibrils. Myxoid and edematous stroma in embryonal type and alveolar pattern in alveolar type wee nost characteristic growth pattern. Immunohistochemically, tumors were positive for desmin, actin and myoglobin in 97%, 27%, and 40%, respectively. Consequently, characteristic cytologic features are important to differentiate rhabdomyosarcomas form other kinds of small round cell tumor and growth pattern is more critical in categorizing histologic subtypes. Desmin is far more useful than actin or myoglobin in the diagnosis of rhabdomyosarcoma.

PURPOSE: This study was designed to verify effects of perineal care with aroma essential oil on urinary tract infection(UTI) in patients with indwelling urinary catheter. METHOD: The research design was non equivalent control group pretest-post test design. The data were collected from March to August, 2005 at C university hospital in Seoul. The subjects were 43 patients who had a indwelling catheter in neurosurgery intensive care unit(NSICU). They were assigned to two groups, 21 subjects to the experimental group and 22 subjects to the control group. The experimental group received perineal care with 3% blending essential oil for 4 days. RESULTS: In the experimental group, white blood cells and bacteria in urine were significantly lower than control group. Bacteria in urine culture was lower in the experimental group at post test. CONCLUSION: Perineal care with aroma essential oil could be an effective intervention to reduce the UTI of patients in NSICU.

The aims of this study were to investigate the present status of skeletal maturation and to compare body composition parameters on the basis of the levels of skeletal maturity in boys aged 9 ~12 years. The subjects participated consisted of 258 elementary school boys. Anthropometric characteristics included body weight, height, sitting height, bone widths, circumferences, and skinfold thicknesses. Skeletal maturation was assessed by the Tanner -Whitehouse II method. Skeletal age was determined by RUS scores (radius, ulna, and short bones). Body composition variables were evaluated by bioelectrical impedance analysis (BIA Model 310). Means and standard deviations were calculated by descriptive statistics. To compare body composition variables among skeletal maturity groups one -way analysis of variance (ANOVA) was applied and Duncan's a posteriori tests. The results showed that RUS scores varied from 298.2 for 9 years to 482.6 for 12 years. TW2 -20 scores were 569.2 for 9 years, 628.8 for 10 years, 701.8 for 11 years, and 814.5 for 12 years. Skeletal ages were 9.7 for 9 years, 10.5 for 10 years, 11.7 for 11 years, and 13.6 for 12 years. It indicates that chronological age was lower than skeletal age in all age groups. Although no significant difference was found in 12 years for body composition according to the levels of skeletal maturity, in general advanced boys had higher body composition variables than retarded boys. In 9 years there were significant differences (p 0.05) among skeletal maturity groups for body mass index, WHR, and WTR. Also, differences were found in 10 years for percent body fat, fat -free mass, and body mass index. In 11 years advanced children (40.4 kg) have statistically significant (p 0.05) higher fat -free mass than retarded children (32.2 kg).

PURPOSE: We evaluated the efficacy and safety of a tension free vaginal tape (TVT) procedure for the treatment of stress urinary incontinence in women. MATERIALS AND METHODS: Forty-one women (32 with genuine stress urinary incontinence and 9 with mixed urinary incontinence) underwent a TVT procedure under spinal, epidural or general anesthesia. Three women experienced previously failed anti-incontinence surgery and nine women experienced previous pelvic surgery. The mean follow-up period was 17.1 0.4 months. RESULTS: The mean operation time was 31.8 1.2 minutes and mean hospital stay was 1.7 0.2 days. There were no significant intra- and postoperative complication. Four patients (9.8%) had immediate postoperative voiding difficulties necessitating an extra procedure (cutting or release of the tape) under local anesthesia. Six patients (14.6%) with de novo detrusor instability were improved by anticholinergics medication and release of the tape. Six (66.7%) of 9 women with urge incontinence were significantly improved or cured after surgery. Success rate was 97.6% in postoperative 3 months, 95.1% in postoperative 12 months. The patients satisfied with this procedure were 38 (92.7%) in postoperative 3 months and 37 (90.2%) in postoperative 12 months. There were no significant changes in the postoperative outcome over time. CONCLUSIONS: We consider the TVT procedure is a safe and effective surgical procedure for the treatment of female stress urinary incontinence, though longer follow-up is necessary to determine long term effect.

PURPOSE: To examine the fate of muscle-derived stem cells (MDSC) after injection into different host conditions and provide an insight for their mechanism of action. MATERIALS AND METHODS: MDSCs differentiated in vitro towards the endothelial lineage and transfected with lentivirus tagged with green fluorescent protein (GFP) were injected into two animal models mimicking vascular diseases: hindlimb ischemia and carotid injury models. Injected cells were tracked at the site of injection and in remote organs by harvesting the respective tissues at different time intervals and performing immunofluorescent histological analyses. Stem cell survival was quantified at the site of injection for up to 4 weeks. RESULTS: MDSCs were successfully tagged with fluorescent material GFP and showed successful implantation into the respective injection sites. These cells showed a higher affinity to implant in blood vessel walls as shown by double fluorescent co-stain with CD31. Quantification of stem cell survival showed a time-dependent decrease from day 3 to 4 weeks (survival rate normalized against day 3 was 72.0% at 1 week, 26.8% at 2 weeks and 2.4% at 4 weeks). Stem cells were also fo und in distant organs, especially the kidneys and liver, which survived up to 4 weeks. CONCLUSION: MDSCs were successfully tracked in different vascular disease models, and their fate was assessed in terms of cell survival and distribution. Better understanding of the donor cell properties, including their interaction with the host conditions and their mechanism of action, are needed to enhance cell survival and achieve improved outcomes.
