The first case report of granular cell tumor was by Abrikossoff in 1926, the tumor has been named with more than 20 different synonyms. It is found usually in the tongue, oral cavity, and the skin. It occurs rarely in the esophagus. Esophageal granular cell tumor is a benign lesion which can be diagnosed by endoscopic biopsy. Large symptomatic lesion can be removed by polypectomy. A 29-year-old female visited our hospital for intermittent epigastric pain and anterior chest discomfort. Endoscopy showed a 0.6 *0.4 cm whitish yellow nodule in the mid-esophagus, 25 cm from the incisor teeth. Endoscopic polypectomy was performed with "O"-type rubber band for endoscopic variceal ligation(EVL). A case of esophageal granular cell tumor conformed by S-100 protein stain is reported with the review of literature.

PURPOSE: This study aimed to examine the effects of oral sildenafil on erectile function according to the number of accompanying cardiovascular risk factors. MATERIALS AND METHODS: The Q3 (the ability to achieve an erection) and Q4 (the ability to maintain an erection) scores of the International Index of Erectile Function (IIEF) were obtained, before and after the administration of oral sildenafil at least 4 times, in a total of 195 patients (mean age: 57.9 8.9 years) with erectile dysfunction. Of these, 125 had 1 (n=76), 2 (n=33) or 3 (n=16) cardiovascular risk factors. The effects of oral sildenafil for each group were compared by mean paired differences of the Q3 and Q4 scores after treatment. RESULTS: The mean Q3 and Q4 scores increased significantly in all patients, regardless of the presence and number of risk factors (p<0.001). The greater the number of risk factors, the lower the Q3 and Q4 scores, while the mean paired differences in the scores before and after treatment were not significantly different between patients without and with cardiovascular risk factors. CONCLUSIONS: Oral sildenafil improves the erectile function in patients with cardiovascular risk factors, and combined erectile dysfunction and the degree of improvement seem to be similar, regardless of the number of cardiovascular risk factors.

4.Diagnostic value of carvernosal artery systolic occlusion pressure: comparison with angiography, duplex sonography and penile brachial index.
Korean Journal of Urology 1992;33(6):1068-1074
Diagnostic value of the pressure difference (PDBC) between brachial artery systolic pressure (BASP) and cavernosal artery systolic occlusion pressure (CASOP) was comparatively analyzed with penile brachial index (PBI), cavernosal artery duplex ultrasonography (CADU) and selective internal pudendal arteriography in 60 cases (30 patients) with suggestive arteriogenic impotence. 1. When arteriogram set as a standard control. the specificity and sensitivity of PDBC were 58.8% 61.8%, those of CADU were 57.1%, 59.4% and those of PBI were 55.8%, 70.6%. 2. When PDBC set as a standard control, the specificity and sensitivity of internal pudendal arteriography were 43.5%, 75.0%, those of CADU were 34.8%, 67.9% and those of PBI were 34.3%. 68.8%. Those results suggest that PDBC is not significantly correlated with internal pudendal arteriogram and it has a limitation in evaluation of arteriogenic impotence. Thus, PDBC should be interpreted in comparison with PBI, CADU and/or arteriogram.

The lesions of central nervous system in tuberous sclerosis often calcify, especially those present in the perivascular region, allowing the computed tomography to make early and definite diagnosis, even when patients intelligence was normal, seizures were absent, or clinical findings were not specific, We report three cases of tuberous sclerosis, which showed pathognomic subependymal paraventricular calcification in brain CT.

This is a case report of a 50-year-old female who presented to our clinic with headache and left temporal pulsatile mass. Aneurysm was revealed incidentally on a computed tomography angiography of her head. Open surgical resection with aneurysmal trapping was performed under local anesthesia. Histological examination demonstrated a true aneurysm of the superficial temporal artery. There was loss of normal elastin in the internal elastin layer. This case report describes the rare entity along with a review of the literature.

BACKGROUND: As the pleural inflammation progresses, exudative pleural fluid becomes loculated rapidly with pleural thickening. Complete drainage is important 13 prevent pleural fibrosis, entrapment and depression of lung function Intrapleural urokinase instillation therapy has been advocated as a method to facilitate drainage of gelatinous pleural fluid and to allow enzymatic debriment of pleural surface. This study was designed to investigate the Predictors of effeotiveness of intrapleural urokinase in treatment of loculated pleural effusion METHOD: Thirty-five patients received a single radiographically guided pig-tail catheter ranging in size from 10 to 12 French Twenty-two patients had tuberculous pleural effusions, and 13 had non-tuberculous postpneumonic empyemas. A total of 240,000 units of urokinase was dissolved in 240 ml of normal saline and the aliquots of 80mL was instilled into the pleura1 cavity via pig-tail catheter per every 8hr. Effectiveness of intrapleural urokinase instillation therapy was assessed by biochemical markers, ultrasonography, and technical details. A greater than 50% improvement on follow-up chest radiographs was defined as success group. RESULT: Twenty-seven of 35 (77.1%) patients had successful outcome to urokinase instillation therapy. Duration of symptoms before admission was shorter in sucess group (11.8α6.9day) than in failure group (26.62α16.5day) (P<0.05). Amount of drained fluid during urokinsse therapy was larger in success group (917.1α392.7ml) than in failure group (613.8α259.7ml) (P<0.05). Pleural fluid glucose was higher in success group (89.7 α35.9mg/dl) than in failure group (41.2α47.1mg/dl) (P<0.05). Pleural fluid LDH was lower in success group (878.4α654.31U/L) than in failure group (2711.1α973.1IU/L) (P<0.05). Honeycomb septated pattern on chest ultrasonography was observed in six of eight failure group, but none of success group(P<0.05). CONCLUSION: Longer duration of symptoms before admission smaller amount of drained fluid during urokinase therapy, lower glucose value, higher LDH value in pleural fluid examination and honeycomb septation pattern on chest ultrasonography were predictors for failure group of intrapleural urokinase instillation therapy.

39 patients with tibial shaft fracture had treated by open reduction and internal fixation with AO DCP and screws applying on the medial surface of the tibia, at the Department of Orthopedic Surgery, Ulsan Dongkang Hospital, from January, 1983 to December, 1985. A clinical study was done on all the 39 cases with the follow-up check over 1 year. In general, because the lateral surface of the tibia is well covered by rich soft tissue, it is popularized to apply the plate on the lateral aspect of the tibia. In our department, we applied the plate on the medial aspect of the tibia, which resulted in mimi-zing soft tissue injuries and, by inserting the screws perpendicular to the surface of the bone, increased stability of the fixation; and therefore resulted in relatively short operation time, relatively low incidences of infection and non-union; but there had been some drawbacks such as focal skin necrosis, hematoma, adhesion after fixatives removal, and cosmetic disfiguring. But there were no problems during the follow up periods. So, this is a recommandable procedure of internal fixation with the plate for the tibial shaft fractures.
