We report a diabetic woman who developed paroxysmal hemichorea during an episode of non-ketotic hyper-glycemia. A MRI showed a high signal intensity on T1-weighted images and a low signal intensity on T2-weighted images in the contralateral putamen. SPECT on the 30th day after the onset revealed an increased blood flow in the contralateral striatum. Although these abnormalities in the left putamen are considered to be the cause of her involuntary movement, the exact pathophysiological mechanisms of these abnormalities are not yet clear and further investigations are needed.

The precise nature of the underlying disturbance responsible for TTP is unknown, but recent work suggests that abnormalities of sodium channels play an important role. There are only a few electrophysiologic studies reported during an attack of paralysis of TTP and the electrophysiologic studies during paralytic attack in our two patients showed the following results, different only in severity. 1.Nerve conduction studies were normal in all the tested sensory nerves. Motor nerves showed normal conduction velocities, but low amplitudes of CMAPs except for median nerve. 2.Needle EMG showed markedly decreased insertional activities, and lowamplitude, short-duration, and polyphasic MUAPS, The recruitment patterns on maximal efforts were markedly reduced. There were no spontaneous activities. 3.Repetitive nerve stimulation of ulnar nerve showed significant incremental responses on digiti quinti muscle, marked during the early phase of stimulation. The degree of incremental responses was proportional to the frequency of stimulation.

PURPOSE: To report the technique of modified Thompson quadricepsplasty with postoperative treatment using string tie and the results for stiff knees. MATERIALS AND METHODS: From June 1987 to June 1997, we evaluated the results of 20 knees of 19 patients who were managed with modified Thompson quadricepsplasty for the stiff knee and were followed up for an average of 29 months (range, 18 to 49 months). We performed modified Thompson quadricepsplasty, which included arthrolysis, anterolateral or lateral approach, transverse incision on tensor fascia lata, release of middle and distal third of quadriceps muslce. If the knee flexion was less than 130 degree, Z-plasty on distal tendinous portion of rectus femoris was performed. Postoperatively, the knees were flexed with string tie for 3 hours. And then the knees were extended for 3 hours. This periodic passive exercise was started by the 21st day after the surgery. RESULTS: The average gain in flexion from preoperative to postoperative was 74.7 degree+/-25.1 degree. At the latest follow-up, the average loss of range of motion from that obtained in the operating room was 5.3 degree+/-7.2 degree. According to Judet's assessment of results, there were 17 excellent and 3 good results. There was one wound infection but it resolved after wound care and intravenous antibiotics for 3 weeks. CONCLUSIONS: The modified Thompson quadricepsplasty and postoperative care with string tie provided good results for the stiff knee.

The authors reported 100 cases of acute subdural hematomas confirmed by operation from Jan. 1972 to Sept. 1975. We discussed the relationship of the type of operation to mortality in acute subdural hematomas. The types of surgical operations were divided in 4 groups. The surgical mortality rate was 19% for frontotemporoparietal craniotomy, 29% for multiple burr holes technique, 42% for craniectomy and 48% for subtemporal decompression with burr holes and total over-all mortality was 36% in our cases. The authors reviewed the literatures described the surgical operative method and it's mortality and so we thought large frontotemporoparietal craniotomy is more valuable method for operation of the acute subdural hematomas.

Purpose:
To predict the presence of tractional retinal detachment (TRD) in eyes with dense vitreous hemorrhage (VH) and proliferative diabetic retinopathy (PDR) by evaluating the status of posterior vitreous detachment (PVD) in fellow eyes using optical coherence tomography (OCT).
Methods:
A total of 44 eyes from 22 patients who underwent vitrectomy due to dense VH with PDR were enrolled. Using OCT, the PVD status in the fellow eye was divided into two groups (incomplete and complete PVD). The incomplete PVD group included eyes without PVD and eyes with partial PVD. B-scan ultrasonography was performed on eyes with dense VH to evaluate the presence of TRD. Both OCT and B-scan images were reviewed by four ophthalmologists (two novices and two experienced), and the interobserver agreement was evaluated.
Results:
There was a difference in the interobserver agreement regarding the presence of TRD in eyes with dense VH evaluated by B scan between novice and experienced ophthalmologists (novice, κ = 0.421 vs. experienced, κ = 0.814), although there was no difference between novice and experienced ophthalmologists in the interobserver agreement regarding the status of PVD in the fellow eye evaluated by OCT (novice, κ = 1.000 vs. experienced, κ = 1.000). All observed TRD during vitrectomy occurred in eyes with incomplete PVD in the fellow eye. Logistic regression analysis revealed a statistically significant relation between TRD and the age of the patient (odds ratio [OR], 0.874; p = 0.047), and between TRD and incomplete PVD in the fellow eye evaluated by OCT (OR, 13.904; p = 0.042).
Conclusions
Evaluation of the PVD status in the fellow eye using OCT may be a useful predictor for detecting the presence of TRD in eyes with dense VH and PDR.

BACKGROUND AND AIMS: This research was conducted in order to study the clinical usefulness and stability of the propofol used for sedation during upper gastrointestinal endoscopy. METHODS: The objective of this research was to study one hundred patients, who were chosen based upon their preference to be examined through diagnostic upper gastrointestinal endoscopy accompanied with propofol from July 1998 to August 1998, and who showed normality in the pulmonary function test and ECG. The elements observed were hemodynamic variations, injection dosage, injection time, recovery time and side effects. RESULTS: All patatints had no recollection of the procedure during gastrointestinal endoscopy. It was found that the older the patients were, the less amount of propofol sleep was indued. Systolic blood pressure, diastolic blood pressure and the mean arterial blood pressure were lowered noticeably after sleep, compared with those before the injection of propofol, while the heart rate hardly changed. CONCLUSIONS: Profopol is believed to be a useful sedative for upper gastrointestinal endoscopy. As blood pressre can be lowered however, a cautious attitude should be considered when injecting propofol in the elderly or in patients who have cardiovascular disease.

Hematogenous spread from tuberculous lesions of other parts of the body represent the origin of intracranial tuberculomas. In most series of the literature, the cerebellum has about two thirds and the cerebral hemispheres about one third of the intracranial tuberculomas. It may occurs as a single lesion, but multiple intracranial tuberculomas varies from 10% to 33% of the cases due to the hematogenous spread. Calcium deposits are rare, occurring in about 6% of cases. Ramamurthi and Varadarajan described the two types of the intracranial tuberculoma; 1. Superficial and vascular type, produces early focal signs of increased intracranial pressure. 2. deep and avascular type, accompanied by signs of increased intracranial pressure. We have been experienced in one case of symmetrical and bilateral cerebellar tuberculomas probably originated from the pulmonary lesion.

PURPOSE: We assessed sexual function by using a questionnaire in women who were diagnosed with stress urinary incontinence and underwent mid-urethral tape sling surgery. MATERIALS AND METHODS: A retrospective survey was conducted of 151 women without evidence of detrusor overactivity or concomitant prolapse who underwent surgery (tension-free vaginal tape or tension-free vaginal tape-obturator) for stress urinary incontinence. The participants filled out a questionnaire regarding their preoperative and 6-month postoperative sexual function. Paired t-tests were used to compare changes over time. The generalized McNemar test was used to compare individual preoperative and postoperative findings. We considered a p-value less than 0.05 as significant. RESULTS: Of the 303 women who fulfilled the inclusion criteria, 204 (67.3%) returned the questionnaire. Of those 204 women, 151 were sexually active before and after surgery. No significant differences were observed after surgery in the frequency or appreciation of intercourse or the extent of sexuality. A significant reduction in leakage symptoms was observed after surgery (p<0.01). Of the 151 women, 29 (19.2%) reported an improvement in satisfaction with intercourse and 23 (15.2%) reported a deterioration after the anti-incontinence procedure. Partner discomfort remained unchanged. Of the 151 patients, 26 (17.2%) patients were unsatisfied with the surgical outcome because of persistence or recurrence of stress urinary incontinence and deterioration in satisfaction with intercourse after surgery. CONCLUSIONS: These results suggest that mid-urethral tape sling operations for stress urinary incontinence improved the continence rate, but had little effect on preexisting sexual disturbances. Additional and larger retrospective studies are warranted to support these preliminary findings.

We reviewed retrospectively 16 cases of renal or perirenal abscess who were admitted to the St. Mary hospital during the period from January 1977 to December 1986. The results were as follows : 1. The average age of the patients was 27 years. 2. The average duration of symptom was 15 days. 3. On laboratory findings, 6 cases (31%) of pyuria and 2 cases (13%) of positive urine culture were seen. 4. Abscess culture was performed in 10 patients and 5 cases of staphylococcus and 2 cases of E. coli were cultured. The remained 3 cases were sterile culture. 5. Predisposing factors were involved in 6 cases (38%). Urologic predisposing factors were 5 cases (31%) and non-urologic predisposing factors were 4 cases (25%). 6. Surgical treatment was performed in 10 cases (63%) by 9 cases of incision & drainage and 1 case of nephrectomy. Non-surgical treatment was successful in 6 cases (37%) by 5 cases of antibiotics only and by 1 case of antibiotics with ultrasound guided percutaneous drainage.
