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.

Tetanus is a neurologic disease which features the muscle spasm as the hallmark. It is an infectious disease with high mortality rate triggered by tetanospasmin produced by Clostridium tetani. This report concerns incidence of tetanus consequent to oriental medical care such as acupuncture and moxibustion. Although the tetanus occurrence has shown a remarkable decline since nationwide vaccinations in some of the developed countries, including Korea, it still remains to be an important issue, to be dealt within Korea, as the majority of the patients are old aged and Korean population is rapidly becoming an aging society. Furthermore, since more elders are coming to rely on Oriental medicine in Korea, the Korean elders are at a higher risk than elsewhere. The lack of medical experiences, including those in oriental medical field, has been hindering early diagnosis of Tetanus. This study aims to encourage rapid and accurate decisions in diagnosis and treatment through reviewing symptoms particularly specific to tetanus, and also to arouse attention to the riskiness of invasive procedures involving skin puncture.

Horizontal Mattress Suture Technique on Microvascular Anastomosis of rat (body weight: 200-250 gm) femoral artery was evaluated. The present study was conducted to compare the horizontal mattress suture with simple interrupted suture on the suture time, patency rate of the sutured vessels, and the histological changes of surgical site of the vessel wall during wound healing period. The mean suture time of the vessel wall with horizontal mattress suture technique was 15 min 49 sec ± 2.14, which is significantly shorter than that of simple interrupted suture technique. The patency rate of the sutured vessel in both groups was statistically not different each other till post-operative 3rd day but patency rate of horizontal mattress suture was higher than that of simple interrupted suture at post-operative 3rd week. The histological findings such as intimal noss, medial degeneration and intimal regeneration were similar in both groups.

To investigate the effect of diazepam on the contractility of the intestinal smooth muscle, longitudinal muscle strip isolated from rat ileum was prepared for myography in isolated organ bath. 1) Basal tone of ileal muscle was reduced by diazepam concentration-dependently. 2) Higher concentrations (30 and 100 microM) of diazepam inhibited (p<0.05, p<0.001) The carbachol-induced contraction in a concentration-dependent manner; but lower concentration of diazepam (10 microM) enhanced (p<0.05). 3) Histamine-induced contraction was inhibited by pretreatment with diazepam in a concentration-dependent manner. 4) Ca⁺⁺-induced tension recovery in calcium-free solution was inhibited in the presence of diazepam concentration-dependently. These results suggest diazepam reduces the contractility of the longitudinal muscle isolated from rat ileum via interference with influx of calcium into the muscle cells.

PURPOSE: Side firing laser prostatectomy(VLAP) is now considered as alternative promise of transurethral resection of the prostate(TURP). This study was designed to compare VLAP to conventional TURP in the efficacy and safety. MATERIALS AND METHODS: There was no significant differences in preoperative clinical characteristics between the TURP group and VLAP group. To evaluate the effectiveness and safety of VLAP, we compared the results of transurethral resection of prostate(TURP, n=115) to laser prostatectomy(VLAP, n=45) in international prostate symptom score(IPSS), maximal flow rate(Qmax), post-voiding residual urine at preoperative, after 1 month, 6 months and 12 months postoperatively. For the VLAP procedure, Nd: YAG was used. Patient was treated with 600micrometer internal reflector fiber covered by crystal glass cadding(SideTrackTM). RESULTS: There was no statistically significant difference in the results between TURP group and VLAP group. TURP group; IPSS of preoperative, after 1 month, 6 months, 12 months was 23.8, 9.0, 9.1, 9.0 and Qmax was 7.8ml/s, 17.0ml/s, 17.1ml/s, 17.6ml/s and residual urine was 159.3ml, 52.7ml, 40.0ml, 34.6ml. VLAP group; IPSS of preoperative, after 1 month, 6 months, 12 months was 22.8, 9.7, 9.8, 9.3 and Qmax was 8.1ml/s, 16.0ml/s, 16.7ml/s, 17.1ml/s and residual urine was 135.7ml, 46.8ml, 34.5ml, 28.1ml. Postoperative period of catheter indwelling and hospitalization was shorter in VLAP group than TURP group(3.7+/-2.0 days vs 5.3+/-1.9 days, 4.5+/-1.6 days vs 6.8+/-3.5 days). CONCLUSIONS: VLAP has no siginificant complications such as postoperative bleeding, TURP syndrome. VLAP would be recommended as following: 1) prostate weight is smaller, 2) physical status is poor, 3) anticoagulant treatment, 4) when patient wants more safe treatment. We had a good results by means of VLAP. The good results come from the use of internal reflecting type laser fiber. These results suggest that VLAP is considered the most promising alternative to TURP.

The most common cause of small bowel obstruction is postoperative adhesion, and besides a hernia, metastatic or primary cancer and small bowel tumors are possible causes. Superior mesenteric artery (SMA) syndrome is a rare cause of upper gastrointestinal obstruction and is associated with debilitating conditions with marked weight loss. SMA syndrome results from the compression of the third part of the duodenum due to the narrowing of the aortomesenteric angle. We report a 28-year-old woman with SMA syndrome after acute gastroenteritis. Her stomach was severely dilated due to the duodenal obstruction and computed tomography showed the compression of the third portion of the duodenum by SMA. She was conservatively cared for and thus favorably improved.
