Synovial cysts are uncommon lesions that may occur within the spinal canal. Most commonly synovial cysts arise from degenerative apophyseal joints, in particular at the L4-5 level, and are associated with spondylolisthesis. We present one case of lumbar synovial cyst located both intraspinally and extraspinally and originated from the defect of the pars interarticularis. The content of the synovial cyst was infected. The patient progressively developed low back pain and fever. The lesion was diag nosed by computed tomography and a magnetic resonance imaging. The synovial cyst was presented a huge lobulacted intraspinal and extraspinal mass and connected with the L4-5 facet joint on the right side. The dural sac was displaced by the intraspinal mass. Relieve of symptoms was achieved with decompressive laminectomy and removal of the mass. The content of the synovial cyst was infected with Staphylococcus aureus confirmed by the synovial fluid culture. The reasons for our report are to describe the previously unreported appearance of this lesion that was huge lobulated intraspinal and extraspinal mass with infected fluid content originated from the defect of the pars interarticularis.

Spontaneous rupture of the quadriceps tendon has heen rarely reported. We experienced four knees of 3 patients. Two patients with chronic renal failure(CRF) had been treated with peritoneal dialysis and the other patient was healthy without significant medical problem. In the CRF patients, laboratory studies were coincided with secondary hyperparathyoidism. Radiologic and operative findings suggested that the repeated minor trauma caused avulsion fracture of the bone near the insertion site of the tendon. Histologic findings revealed no elastosis of the tendon and no deposit of amyloid in the quadriceps tendon. In the non-CRF case, there was normal lahoratory data, and the rupture occurred at the musculotendinous junction, suggesting sudden contracture of the muscle causing failure without trauma history. All cases were treated successfully with open repair of the quadriceps tendon. It could be summarized that the site of spontaneous rupture in the CRF and normal patient were different.

A preliminary study was conducted to evaluate the immediate postoperative recovery and socioeconomic efficacy with the surgical release of Carpal tunnel syndrome by double incision technique. Sixty cases of carpal tunnel syndrome were operated by one surgeon between 1993 and 1995 and 44 cases in 39 patients were available for this study. Surgery was done under axillary block and patients were evaiuated preoperatively, 3 weeks and 6 weeks each postoperatively. The evaluation was focused on the immediate recovery in terms of subjective symptoms of pain and paresthesia, local tenderness, strength of grip power and pinch power and postoperative disability. 1l was noted that surgical release of carpal tunnel syndrome utilizing double incision technique was as effective as seen in the endoscopic release in terms of quicker recovery of pain, local tenderness and strength. It was also noted that this double incision technique was as safe and economically beneficial as observed in the conventional open procedure.

OBJECTIVES: To investigate the frequency and clinical characteristics of premenstrual syndrome(PMS)/premenstrual dysphoric disorder(PMDD) in high school students, and determine the correlates of PMS/PMDD in association with comorbid depression and anxiety. METHODS: A total of 1688 students were recruited from 5 high schools in Seoul, Korea. Subjects completed the questionnaire composed of scales to measure premenstrual symptoms, depression, and anxiety, as well as sociodemographic and reproductive variables. Subjects were categorized into 3 groups by using the Premenstrual Symptom Screening Tool(PSST) to determine the frequency and clinical characteristics of PMS/PMDD. Multivariate logistic regression was used to identify the correlates of PMS/PMDD. RESULTS: The frequency of moderate to severe PMS and PMDD was 20.1% and 6.4%, respectively. Irritability (78.8%), fatigue(76.4%), and emotional sensitivity(69.8%) were common premenstrual symptoms, and functional impairment in academic performance(67.1%) was dominant. Dysmenorrhea[odd ratio(OR)=3.68, 95% confidence interval(CI) 2.45-5.55], family history of PMS(OR=1.91, 95% CI 1.35-2.71), and use of oral contraceptive (OR=1.85, 95% CI 1.16-2.94) were associated with the increased risk of PMS/PMDD after adjustment for depression and anxiety. Negative attitude to menses(OR=15.60, 95% CI 3.61-67.42) was associated with the increased risk of PMS/PMDD, particularly in subjects without depression and anxiety. CONCLUSIONS: PMS was common, as the frequency of PMS more than moderate severity including PMDD exceeded 25%, and disrupted daily functioning in adolescents. PMS is associated with various sociodemographic and menstrual characteristics, and these associations are affected by comorbid depression and anxiety.

This study was undertaken to investigate the morphologic changes following flushing, preservation and reperfusion procedures in a canine lung allotransplantation model. Donor lungs were flushed with modified Euro-Collins (MEC) solution, low potassium dextran glucose (LPDG) solution or University of Wisconsin (UW) solution, then stored at 10oC for 20 hours. Light microscopic and electron microscopic features of the lungs were examined after flushing, preservation and 2 hours after reperfusion. After flushing light microscopy showed focal mild alveolar collapse and interstitial edema. After preservation the lung tissue showed multiple foci of alveolar collapse, consolidation, and alveolar epithelial cell damage. After reperfusion the lung tissue showed diffuse alveolar collapse, consolidation and many destroyed cellular debris in the alveolar lumina. After flushing electron microscopy showed focal alveolar collapse and mild swelling of type I epithelial cells. After preservation both type I epithelial cells and endothelial cells were swollen and destroyed focally. Some type I epithelial cells were detached from the basal lamina. The endothelial cells showed luminal protrusion of tactile-like structure and vacuoles of the cytoplasm. After reperfusion the lung tissue showed fibrin material in the alveoli, prominent type I epithelial cell swelling with fragmented cytoplasmic debris and marked endothelial cell swelling with vacuoles or tactile-like projections. The alveolar macrophages showed active phagocytosis. After preservation scanning electron microscopic examination of the pulmonary arteries showed multiple patchy areas of swelling or conglomerated lesions in the inner surface of the pulmonary arteries. In conclusion, the ultrastructural changes associated with flushing were mild in severity, the donor lungs were injured during the preservation, and further damage occurred during the reperfusion.
