Development of acetabulum and epiphysis of the femoral head following reduction in seventy-four patients with ninty-one congenitally dislocated hips were assessed radiologically. Acetabular index, CE angle of Wiberg, neck-shaft angle of the femur and overgrowth of the pelvis and femur were measured according to the various treatment. To evaluate results, the method of treatment was divided into four groups; closed reduction, open reduction, open reduction combined with pelvic osteotomy and modified Klisic operation (open reduction, pelvic osteotomy, femoral osteotomy and so on). Each treatment was compared with three subgroups according to ages; first subgroup was belong to patients under one year of age, second from one year to three years, third over three years. This paper agrees to Harris (1976) and Lindstrom (1979) about improvement of acetabular index and CE angle of Wiberg that showed a rapid rate of repair in the first 6 months and thereafter slowly progressed to normal range of degree. Overgrowth of pelvis and femur was also noticed in cases of hips treated pelvic and/or femoral osteotomy, moreover even in cases of open reduction only. The goal of this preliminary investigation may be supposed to propose the idea which method of treatment to the first visiting patient will approach the most satisfactory final result.

PURPOSE: To compare the pullout strength and insertion torque of proximally tapered screw (PT) with fully tapered screw (FT) and to investigate the correlation between the pullout strength and bone mineral density, morphology of pedicle, and insertion torque of the screw in osteoporotic lumbar spine. MATERIALS AND METHODS: Fifteen osteoporotic lumbar vertebrae from four white human cadavers were used. Bone mineral density, pullout strength and insertion torque were measured by dual energy x-ray absorptiometry, MTS and torque screw driver individually. RESULTS: The FT screw provided greater pullout force and insertion torque than the PT screw in 12 of 15 vertebrae tested (p<0.01). Pullout strength was correlated with insertion torque in PT (r=0.666, P=0.0006) and FT (r=0.464, P=0.19) screws. CONCLUSIONS: Results of this study indicate that the FT screws provide higher pullout strength and insertion torque than PT screws in osteoporotic lumbar spine and suggest that the development of tapered minor diameter may lead to an improved pedicle screw with high pullout strength and insertion torque. Nevertheless, further study is needed to investigate the effect of tapering the minor diameter on the mechanical bending strength of the screw.

Changes in the urinary tract associated with prolapse uteri have been known for a long time. However, women who have a prolapse uteri are often free of symptoms. When symptoms are present they are above all, urinary tract infection, difficulties in emptying the bladder, increased frequency of micturition, stress incontinence, and ureteral obstruction. We reviewed 82 patients who had prolapse uteri of grade II and III in order to evaluate the effects of prolapse uteri to the urinary tract. There were 5 patients (6.1%) who had urinary tract infection and urine culture revealed the growth of E. coli in 3 of them. Only 1 patient (1.2%) had high blood urea nitrogen. 51 (62.2%) out of 82 patients showed voiding problems (frequency, voiding difficulty, stress incontinence) and 53 (64.6%) out of 82 patients had cystocele of several degrees, but there was no difference between the degree of prolapse uteri and both voiding problems and cystocele. Vaginal hysterectomy with anterior and posterior colpoperineorraphy was performed in 68 (88. 3%) out of 77 patients who underwent surgical treatment by gynecologists, and in 22 (91.7%) out of 24 patients who showed difficult urination, their symptoms were improved immediately after surgery. Bladder neck suspension was performed simultaneously in 3 patients who showed stress urinary incontinence with prolapse uteri. Intravenous pyelography or abdominal ultrasonography was performed to evaluate accompanied ureteral obstruction in 8 patients who had severe cystocele. In 5 patients, upper tract deteriorations were noted. Bilateral hydroureteronephrosis was found in 3 patient, unilateral lower ureteral dilatation in 1 patient, and severe parenchymal damage in 1 patient. In conclusion, we believe that urologist should participate in managing those patients who have prolapse uteri to improve their voiding problems and prevent upper urinary tract deterioration.

The sleep homeostatic response significantly affects the state of anesthesia. In addition, sleep recovery may occur during anesthesia, either via a natural sleep-like process to occur or via a direct restorative effect. Little is known about the effects of isoflurane anesthesia on sleep homeostasis. We investigated whether 1) isoflurane anesthesia could provide a sleep-like process, and 2) the depth of anesthesia could differently affect the post-anesthesia sleep response. Nine rats were treated for 2 hours with ad libitum sleep (Control), sleep deprivation (SD), and isoflurane anesthesia with delta-wave-predominant state (ISO-1) or burst suppression pattern-predominant state (ISO-2) with at least a 1-week interval. Electroencephalogram and electromyogram were recorded and sleep-wake architecture was evaluated for 4 hours after each treatment. In the post-treatment period, the duration of transition to slow-wave-sleep decreased but slow wave sleep (SWS) increased in the SD group, but no sleep stages were significantly changed in ISO-1 and ISO-2 groups compared to Control. Different levels of anesthesia did not significantly affect the post-anesthesia sleep responses, but the deep level of anesthesia significantly delayed the latency to sleep compared to Control. The present results indicate that a natural sleep-like process likely occurs during isoflurane anesthesia and that the post-anesthesia sleep response occurs irrespective to the level of anesthesia.

Extra-adrenal paragangliomas are rare tumors of neural crest origin, usually arising from the carotid bodies, the glomus jugulare, or the retroperitoneum. And, though ten percents of cases are presented with malignancy, it`s prognosis is relatively good. In genitourinary area, there are a few reported cases of extra-adrenal paragangliomas of the urinary bladder and the spermatic cord. Herein, we report a case of paraganglioma arising in the scrotum, which is an extremely rare location.

Gas-forming infections in the genitourinary tract are usually associated with diabetes mellitus, and emphysematous pyelonephritis is a common disease among them. However, gas forming infection occurring in the scrotum is extremely rare. We experienced a case of gas-forming scrotal wall abscess in a 45-year-old diabetic man, who showed clinical symptoms mimicking acute epididymo-orchitis.

This research investigated on the medical recorder manpower relation by before / after medical record computerization for the object of 51 hospitals in 1998 year. Judging from the situation before / after computerization shown on this investigation, the number of personnels was more increased since computer work than manual work, and the medical recorder present conditions by years show that they have been gradually increasing. This is considered why affairs diversely change according to computerization, the auxiliary recorder present conditions shows the reduction of 98 year in comparison with 94 year. This is regarded that personnels were reduced by facilities like existing transporting pipes. Accordingly, vast data are produced and utilized in the medical record department(room) too, therefore information will be quickly / correctly dealt for this. The times invested for simple affairs will be easily diminished by making existing simple affairs be computerized, and so personnels will have to be invested to earnestly / diversely utilize vast information not to reduce personnels in proportion to diminished times.
