BACKGROUND: Recently the percutaneous transradial approach for coronary angiography, transluminal coronary angioplasty or coronary stention were reported but there was no report in Korea. So we tested the safety and efficacy of the transradial appreach for coronary angiography in Korean. METHODS: Eleven patients(male 9, female 2, mean age 59.3 yeal old)with chest pain underwent percutaneous transradial coronary angiography with 5 french multipurpose catheter. We evaluated clinical efficacy and observed complication of percutaneous transradial coronary angiography by physical examination and DOpple ultrasonography of puncture site of radial artery. RESULTS: Right coronary angiography and left ventriculography were performed successfully in all cases, but left coronary angiogrphy was failed in three cases. In another three cases, the patient complained of arm pain which was aggravated during manipulation of the catheter. After the procedure, it took 10.3 minutes to stop the bleeding at the puncture site, Clinically significant complications were not observed after the procedure. The patients were not restricted to bed at all since the completion of the procedure. CONCLUSION: In our limited dexperience, percutaneous transradial coronary angiography could be performend on the outpatient basis without significant complications.

Respiratory effects of acute coronary embolism were studied in mongrel dogs. Coronary embolism was produced by Agress's method and respirtory effects were observed for two hours. In the experimental group, in which coronary embolism was produced, there were relative decreases in respiratory rate and arterial oxygen saturation along with relative increases in tidal volume, minute ventilation, ventilation equivalent and arteriovenous oxygen difference compared to those in the control group. However, differences in these various measurements between tow groups, those in tidal volume and arterial oxygen saturation, have greatly diminished in two hours. These facts suggest that changes in respiratory rate, minute ventilation, ventilation equivalent and arteriovenous oxygen difference in the experimental group are early but short-lasting responses to acute coronary embolism, whereas changes in tidal volume and arterial oxygen saturation occur early and last longer.

Meningiomas causing intracranial hemorrhage are rare, and hemorrhage from a lateral ventricular meningioma seems to be even rarer. We report a case of trigonal meningioma in a 43-year-old woman who presented with intraventricular hemorrhage, and describe the CT, MRI and angiographic findings.

Renal blood flow was measured by single injection technique of HippuranI13 in 13 patients with chronic glomerulonephritis and 11 control subjects. There was a significant decrease in renal blood flow in chronic glomerulonephritis particulary in those with elevated blood urea nitrogen. Renal blood flow was inversely proportionate to renal vascular resistance but no correlation was noted between renal blood flow and creatinine clearance.

PURPOSE: To establish the incidence of deep vein thrombosis among Koreans after primary total hip arthroplasty and the usefulness of color doppler ultrasonography for routine noninvasive screening for deep vein thrombosis. MATERIALS AND METHODS: We performed prospective, randomized routine venography and color doppler ultrasonography before and after operation in a consecutive series of 89 primary total hip arthroplasty in which no form of prophylaxis was used. RESULTS: Of the 89 cases, eleven (12.4%) were found to have deep vein thrombosis (three proximal veins and eight distal veins) by bilateral venography. Most of the thromboses except two were asymptomatic. No patient had a symptomatic pulmonary embolism. Statistical analysis of risk factors, age, gender, weight, height, fixation method, and duration of operation time, were performed and there was no statistical difference (P>0.05). The reliability of color doppler ultrasonography for detection of deep vein thrombosis was demonstrated. CONCLUSIONS: We found insufficient evidence to recommend routine thromboprophylaxis in primary total hip arthroplasty among Koreans. The authors recommend that routine bilateral color doppler ultrasonography screening be considered after primary total hip arthroplasty for detection of deep vein thrombosis

The purpose of this study was to elucidate the epidemiology and the clinical characteristics of herpes zoster and chicken pox. 703 patients with herpes zoster and 237 patients with chicken pox who were seen at the Department of Dermatology, St. Marys Hospital during 8 years were taken for this retrospective study. Both groups of the patients were evaluated in regard to annual, seasonal and monthly incidence, age incidence and sex ratio. Patients with herpes zoster were further assessed concerning associated conditions, dermatomic distributions and complications. The results were as follows, 1. The annual rate for chicken pox ranged from 0.03% to 0.18% (mean 0.13%) and revealed no epidemics, however, its incidence was higher in early summer and winter. There was no sexual difference. Chicken pox was seen most. frequently in the 0-9 year age group (91.1%). 2. The annual rate for herpes zoster ranged from 0.23% to 0.52% (mean 0.38%). There were no significant annual, seasonal and monthly variations, and there was a. equal sex ratio. Herpes zoster was seen most frequently in the 50-59 year age group (19.1%) 3. The frequencies of the associated conditions in herpes zoster, in descending order, were infectious disease (2. 7%), diabetes mellitus (2.3%), malignant neoplasm(1. 4%), immunosuppressive drug (l. 4%), autoimmune disease (0.6%), and radiation therapy (0.4%). 4. The dermatomic involvement of herpes zoster was most frequent on thoracic dermatome (53.5%) and others were cervical (16.5%), lumber (10.1%), ophthalmic branch of trigeminal nerve (8.8%), sacral (1.6%), maxillary branch of trigemenal nerve (1.3%), mandibular branch of trigemical nerve (0.6%) and facial nerve dermatome (0.1%). The incidence of involving two different dermatomes was 2.9% and was most common on cervicothoracic dermatome (1.8%). However, one case of cervico thoracic dermatome showed bilateral involvement. 5. The most common complication of herpes zoster was postherpetic neuralgia (6.5%) and others were secondary bacterial infection (2.6%), keratoconjunctivitis (0.6%), keloid formation (0.3%), generalized varicelliform eruption (0.1%), Ramsay-Hunt syndrome (0.1%) and recurrent herpes zoster (0.1%). The mean age of incidence for postherpetic neuralgia was 58.4 years and its incidence was the highest over 70 years (39.5%). Postherpetic neuralgia was most frequently seen in the involvement of ophtalmic branch of trigeminal nerve.

Background: Bone grafts can provide an optimal environment for permanent tooth to erupt and enhance the stability of the alveolar maxilla. Although autologous bone is an optimal source for osteogenesis, its inevitable donor site morbidity has led to active research on bone substitutes. This study was designed to evaluate the safety and feasibility of using biphasic calcium phosphate (BCP; Osteon) as a bone substitute in dogs. Methods: Bilateral third and fourth premolars of four 15-week-old mongrel dogs were used. All teeth were extracted except the third premolar of the right mandible, which was used as a control. After extraction of the premolars, each dog was administered BCP (Osteon), demineralized bone matrix (DBM; DBX), and no graft in the hollow sockets of the right fourth premolar, left fourth premolar, and left third premolar, respectively. Radiographs were taken at 2-week intervals to check for tooth eruption. After 8 weeks, each dog was sacrificed, and tooth and bone biopsies were performed to check for the presence of tooth and bone substitute particle remnants. Results: Four weeks after the operation, permanent tooth eruptions had started at all the extraction sites in each dog. Eight weeks after the operation, all teeth had normally erupted, and histological examination revealed BCP particles at the right fourth premolar. Conclusion: In all four dogs, no delay in the eruption of the teeth or shape disfigurement of permanent teeth was observed on gross inspection and radiologic evaluation. On histological examination, most of the BCP and DBM were replaced by new bone. Bone substitutes can be used as graft materials in patients with alveolar clefts.

We performed this study to analyse the morbidity and mortality of stoma formation in infants and children over a 17-year period. Thirty-seven stoma formations were performed in 37 patients: 21 for anorectal malformation, 9 for Hirschsprung's disease, 3 for necrotizing enterocolitis, 2 for multiple ileal atresia, 1 for volvulus neonatorum with perforation, and 1 for diaphragmatic hernia with colon perforation. There were 26 boys and 11 girls with a mean age of 0.4 years. Complications after stoma formation were encountered in 12 patients(32.4%) and included stomal prolapse, stenosis, retraction, dysfunction, skin excoriation and parastomal hernia. Four patients(10.8%) required stomal revision. The incidence of complications was neither related to the age nor to the primary indication for the stoma formation, but sigmoid colostomy was associated with a lower complication rate compared to transverse colostomy(22.1% versus 42.1%, P<0.05). Five patients died, but only one(2.7%) was dead, which was directly related to stoma formation. Eighteen of these children subsequently underwent stoma closure which was associated with complications in six patients(33.3%). The most common complication after stoma closure was wound sepsis in 4 children. In conclusion, because the significant morbidity of stoma formation still exists the refinements in surgical technique may help in reducing the incidence of complications and a sigmoid loop colostomy should be used whenever possible.
