Synovial sarcoma is comparatively uncommon and highly malignant tumor, which usually arises in proximity to a joint and may affect the adjacent bones. Occurence in finger and severe bony involvement are rare. We present a case of synovial sarcoma of the thumb, because the tumor arose in an unusual site and was characterized by severe bony destruction.

A 26-year-old man with a one-year history of asthma and sinusitis presented with bilateral pleural effusions, patch basilar infiltrates on a chest x-ray and a pericardial effusion on an echocardiogram. The peripheral blood showed marked eosinophilia. An obstructive pattern was also observed during the pulmonary fuction test, which was responsive to bronchodilator inhalation. Nerve conduction studies showed right sural neuropathy. Thoracentesis yielded an acidotic exudative effusion with low glucose, low C3 and eosinophilia. An open lung biopsy revealed an eosinophilic interstitial pneumonitis associated with a necrotizing eosinophilic vasculitis, and granulomatous inflammation foci. In the literature, pleural effusions were reported in 29 percent of Churg-Strauss patients, but the number of effusions was low and their characteristics have not been well described. This report describes the characteristic findings of pleural fluid and its histologic features in a case of classical Churg-Strauss syndrome.

In an approach known as pharmacogenomics, many psychopharmacologists hope to match depressive patients to specific drugs based on the patients' genetic profiles. Many researchers and pharmaceutical companies are investing their efforts and vast amount of money in the pharmacogenomic aspects of many diseases. The numbers of pharmacogenomic reports are relatively small in the field of antidepressants because, in part, depressive disorders are multifactorial diseases with diversity of pathophysiology. In this review, the usefulness of therapeutic drug monitoring, phenotyping and genotyping of drug metabolizing enzymes before administration of antidepressants to depressive patients was discussed. Pharmacodynamic aspects of antidepressants, focused on the results of former studies about the relationship of the polymorphisms of the several genes (serotonin transporter genes, serotonin receptors, etc) and drug response, were also discussed.

A clinical analysis was done on 129 patients (131 cases) of the ankle fractures that were admitted and treated in Orthopedic Department, Inchon Christian Hospital from January 1973 to December 1980. The following results were obtained: l. Of the 129 patients, male was 104 patients and female 25 patients, the average age of the patients was 37. 2. The main cause of the injuries was traffic accident (38.2%), and the remain causes were industrial accident (28.2%), fall down (18.3%), slip down (11.5%), and sports injury (3.8%) in order. 3. The most common type by Lauge-Hansen classification was supination-external rotation type (37.4%). 4. In method of treatment, operative treatment was done in 72 cases and nonoperative in 59 cases. 5 The average duration of the cast immobilization in nonoperative treatment was 8 weeks and operative 7 weeks. 6. The better result was obtained by operative treatment than nonoperative one. 7. The most poor result was noticed in pronation-external rotation type according to Lauge-Hansen classification. 8. We agree that the accurate reduction of the lateral malleolus make the talus in good anatomic position in ankle joint. 9. We agree that Lauge-Hansen classification is useful in diagnosis and treatment of ankle fracture.

OBJECTIVE: To examine the effects of two stimulation waveforms on wound healing in rats. METHOD: 30 Sprague-Dawley rats with a 7-mm diametrical round incision including skin and subcutaneous tissue on the dorsum were divided into three groups. A(n=10) and B groups(n=10) were given rectangular and triangular monophasic pulsed current 1 hr daily until the wound healed completely (duty cycle 10%, absolute spatial current density 0.022 mA/cm2 for A group and 0.011 mA/cm2 for B group), and C group (n=10) received no electrical stimulation. As the indicator of wound healing effect, percentage of reduction in wound area, duration of complete healing and antibacterial effect were evaluated and statistically compared among three groups. RESULTS: The mean values of percentage of reduction in wound area were 75.1+/-3.0% for A group, 74.2+/-5.1% for B group and 68.7+/-5.4% for C group. The mean values of duration of complete healing were 11.1+/-1.3 days for A group, 12.0+/-1.4 days for B group and 16.1+/-1.0 days for C group. The mean antibacterial effect were 0.5+/-0.5 for A group, 0.6+/-0.5 for B group and 2.1+/-0.6 for C group on 2 days post wounding, and 0.4+/-0.5 for A group, 0.5+/-0.5 for B group and 1.4+/-0.7 for C group on 6 days post wounding. Although those for A and B groups were significantly different from those for C group, no significant difference in all values of three indicators existed between A and B groups. CONCLUSION: Results suggest that two stimulation waveforms have no significantly different effects on wound healing in rats.

PURPOSE: To report herein on Nystagmus Acuity Estimator Function (NAEF) based on the foveation time, obtained by analyzing waveforms of infantile nystagmus patients and comparing the results with the patients' actual visual acuity. METHODS: Electro-oculographic data of 27 patients with infantile nystagmus were reviewed. Data of patients only with jerk type nystagmus and reliable visual acuity were analyzed. The foveation time was measured, and NAEF was calculated and compared with the patients' actual best corrected visual acuity. RESULTS: A correlation analysis of the patients' best corrected visual acuity with NAEF was performed, and the retrieved coefficient was 0.4266. The p-value calculated using the Pearson correlation coefficient was 0.0282, implying that high NAEF correlates positively with visual acuity. CONCLUSIONS: Estimated visual acuity, calculated based on the waveforms, positively correlates with the patients' actual visual acuity with statistical significance. However, since the foveation time can be measured only in the patients with jerk-type nystagmus waveforms, further study should be performed on the measurement of the foveation time with other waveforms. Furthermore, the present study shows that such analysis is possible with electrooculogram settings in most general hospitals.
