The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n=16, 100%), hyperattenuation of MCA (n=3), obscuration of lentiform nucleus (n=6), loss of insular ribbon (n=6) and subtle low density in hemisphere (n=5). The most frequent findings was effacement of cortical sulci in our study, and it was though to be the most important sign of early acute cerebral infarction.

We analyzed the MR findings of spinal epidural mass in 23 patients retrospectively. MR images were performed at 1.5T unit. The lesions were confirmed as metastasis(12 cases), lymphoma (2 cases), leukemia(1 cases), multiple myeloma(2 cases), meningioma(3 cases), neurofibroma(1 case), dysraphism with lipoma(1 case) and lipomatosis(4 cases), Most MRI examinations consisted of T1, proton density and T2 weighted sagittal imaging of the spine, with additional pulse sequences or image planes as needed for clarification. The level of the spinal epidural mass was cervical spine level in 2 cases, thoracic in 15 cases, lumbar in 7 cases, and sacral in 2 cases. The location of epidural mass within the spinal canal was eccentric in 20 cases, multiple in 2 cases, and encircled in 4 cases. Paraspinal mass was seen in 11 cases. Signal intensity of epidural mass was variable. The marrow of spine revealed low signal intensity(SI) on TIWI and high SI on T2WI in 14 cases. In conclusion, MRI is a useful diagnostic tool for the evaluation of spinal epidural mass.

OBJECTIVE: This study was done to evaluate the risk factors and prevalence of symptom-giving pelvic girdle relaxation in pregnant women. METHODS: Three hundreds thirty-two postpartum women were asked to fill out a questionnaire within one week after their parturition. The diagnostic criteria of this lesion were adopted from the Norwegian Medical Association's and Larsen's criteria. The questionnaire were included age, parity, BMI(kg/cm2), weight gain during the pregnancy, history of symptom giving pelvic girdle relaxation in previous pregnancy, level of exercise and vocational status during and before the pregnancy and baby's birth weight. The answers were evaluated to determine the risk factors. The correlation was tested by student t-test and logistic regression. RESULTS: The prevalence of symptom-giving pelvic girdle relaxation during pregnancy was 18.9%. The history of symptom-giving pelvic girdle relaxation in previous pregnancy, multiparity and the absence of regular exercise before and during pregnancy showed correlation with symptom-giving pelvic girdle relaxation in pregnancy (p<0.05). CONCLUSION: It is suggested that women who experienced symptom-giving pelvic girdle relaxation in previous pregnancy should be checked for this lesion before pregnancy. Regular exercise is required to lower the incidence and lessen the severity of this lesion in pregnancy.

Maintenance of normal rate of tear production and elimination is essential for the proper controlled envionment for the cornea and the conjunctiva. We analyzed tear turnover rates in normal subjects, which mainly depend on tear production. We scanned 65 eyes of 36 normal subjects after instillation of 2% fluorescein solution 1u into the lower conjunctival fornix, using fluorophotometer (Fluorotron Master). After instillation of fluorescein solution, we scanned the eyes every 3 minutes for 30 minutes to measure tear film fluorescence. We calculated the tear turnover rate using tear film fluorescence valuse. Mean tear turnover rates were 12.3+/-6.6 %/min in normal subjects, 12.7+/-6.9 %/min in men, and 11.7+/-6.6 %/min in women. Mean tear turnover rates of men did not differ significantly from those of women (p>0.05). Mean tear turnover rates of younger subjects(25 years old~40 years old) (16.2 +/-7.4 %/min) were found to be significantly higher than ghose of older subjects(41 years old~73 years old) (9.1+/-40 %/min) (p<0.05). The morning tear turnover rates (13.5+/-1.6 %/min) were found to be higher than those for the afternoon (10.2+/-4.9 %/min), but the differences were not significant(p>0.05). We think that this study might be useful to study the diagnosis and treatement of tear secretory system disorders.

Calcaneus was the most commonly involved bone among the tarsal bone fractures. Although various methods have been practiced in treating calcaneal fractures, controversy exists between conservative and operative ones. Also there have been many complications such as persistent pain and limitation of motion on subtalar joint which compromised final result. The purpose of this study is that open reduction of the subtalar joint, especially posterior facet joint, could reduce the complications. Twenty seven cases of displaced intra-articular fracture of calcaneus were treated with open reduction, internal fixation, and cancellous bone graft from 1984 to 1989 at the Department of Orthopedic surgery, Kang-Nam General Hospital Public Corporation. Seventeen cases were analysed with more than one year follow-up and summarized as follow:1. All of the cases were the type IV and V on the basis of Rowe's classification. 2. The lateral approach was used in all cases. 3. The pre-operative Bohler's angle was from −30°to 15°(average −1.4°). The postoperative Bohler's angle was from 15°to 40°(average 24.5°), which was increased significantly. 4. Based on Rowe's grading, excellent and good results were obtained 13 cases. 5. Among 3 cases of fair result, arthritis of the subtalar joint occurred in 2 cases and peroneal spasm in one. In one case of poor result, postoperative infection occurred. 6. It was thought that open reduction of the posterior facet joint of calcaneus could restore the congruity of subtalar joint near to normal, and contributed to a large extent to the decrease of foot pain commonly developed after calcaneal fracture.

Myasthenia gravis is a disorder characterized by fluctuating muscle weakness. This is frequently associated with thymoma or thymic hyperplasia, and thymectomy is an important step of treatment. We present one case of primary wquamous cell carcinoma of the thymus in myasthenia gravis. Review of literature indicate relative good prognosis.

Primary small cell carcinomas of the prostate are rare, and their histogenesis and clinical behavior remain poorly defined. The origin of small cell carcinoma remains uncertain, but several hypothesis has been put forward, one of this is that the tumor is derived from the argentaffin or argyrophil cells normally present in the prostate, and the other is that arises from the totipotential basal or reserve cells of the prostatic acini. Primary small cell carcinoma of the prostate is a highly aggressive tumor. causing widespread metastasis and early death. The mean survival is 5 to7 months after diagnosis of the small cell carcinoma regardless of the proportion of small cell component or cell size. We report one case of primary small cell carcinoma of the prostate with brief review of literatures.

PURPOSE: The purpose of this study is to evaluate the CT and MR findings of brain absecss with emphasis on the thickeness and signal intensity of abscess wall. MATERIALS AND METHODS: Twenty CT scans and seven MR studies of 23 patients with brain abscess (27 abscesses) were retrospectively reviewed with respect to thickeness and signal intensity of abscess wall, shape and size of abscess, etc. Thickness of abscess wall was measured in the greatest abscess diameter on the CT scans and MR images obtaihed after intravenous administration of contrast material. RESULTS: Enhancing abscess wall was 2mm--6mm (average 3mm) thick. The abscess wall was uniform in thickness in 14 cases (52%), thinner in the roedial wall than lateral wall in 8 cases (30%), and thicker in the medial wall than lateral wall in 5 cases (18%). Signal intensity of abscess wall was isointense relative to gray matter on Tl-weighted MR images and hypointense on both proton- and T2-weighted MR images in 7 out of 8 lesione (88%). The inner margin of the abscess wall was smooth in 14 (52%) and irregular in 13 lesions (48%). The outer margin was smooth in 15 (55%) and irregular in 12 lesions (45%). The size of the abscesses was variable, ranging from lcm to 6cm in diameter. They were round (16 cases), elliptical (6 cases), or multilobulated (5 cases) in shape. Satellite or daughter abscesses were found in 5 patients. CONCLUSION: Abscess wall showed variable thickness in the medial and lateral walls with no specific findings. Other CT and MR findings were also nonspecific, although hypointensity of abscess wall on T2-weighted MR images may be helpful in diagnosis of brain abscess.
