Computerized tomography(CT) has proven to be far superior to other diagnostic studies in the detection of intracranial lesions after head injuries. The procedure is especially appropriate for early and accurate diagnosis because it can be done quickly with no discomfort and minimal risk. CT was utilized as a screening diagnostic procedures in 100 consecutive patients of head injuries who were alert and neurologically no deficits in a 8 months period. 11 abnormal CT Scans found at 10 patients:six epidural hematomas, two intracerebral hematomas, one sudural hygroma and one temporal contusion. The cases presented are discussed in light of pertinent literature.

PURPOSE: To evaluate the characteristic CT findings of neuroblastoma, we studied neurobalstomas. METHODS AND MATERIALS: We analysed CT findings of available 25 cases among pathologically proved 51 neurobalstomas from Jan. 1983 to Sept. 1990. RESULTS: The most frequent site of origin is adrenl gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows:Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently septated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymphnodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neurobalstomas and 25% of mediastinal neuroblastomas. The most common organ of contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. CONCLUSION: We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings.

Rupture of an internal carotid artery pseudoaneurysm is a rare but lethal complication in patients with nasopharyngeal cancer. Here, we report a case of severe nasal bleeding from a left petrous internal carotid artery aneurysm after chemoradiotherapy in a patient with nasopharyngeal cancer. A 76-year-old man who was being treated with concurrent chemoradiotherapy and who had achieved a complete response for 14 months developed massive epistaxis . A postnasal space computed tomography scan showed an enhanced nodular lesion at the left petrous internal carotid artery, and angiography revealed a pseudoaneurysm measuring 11.5x9.1 mm in the left internal carotid artery. Bleeding was well controlled with endovascular occlusion using a coil. The patient showed no recurrence of bleeding during follow-up.

Vasoactive pharmacotherapy is now being widely used as practical and reliable method for the treatment of the patients with erectile dysfunction. But the individual vasoactive agent has limitations in its clinical success and potential for side effects. So, the synergistic effect and low drug volume of each vasoactive drug in polypharmacotherapy of erectile dysfunction have made it possible to reduce both systemic and local complications with excellent success rate. A total of 223 patients with erectile dysfunction underwent a trial of intracavernous self injection therapy with Trimix(the mixture of papaverine, phentolamine and prostaglandin E1). Major underlying diseases were DM(115patients, 51.6%), hypertension(11 patients, 4.9%), spinal injury(three patients, 1.3%) and prior pelvic surgery(three patients, 1.3%). The volume of drug used ranged between 0.04 and 0.6ml(average:0.19ml). After a mean followup of 7.6 months(3-15 months), 141 patients(63.2%) left in the home injection program and among them, 125 patients(88.6%) had very high satisfaction. The drop-out rate was 36.8%(82 of 223) with most of the cases during early home phase. The causes of drop-out were the fear of needle or injection, inadequate response to injection, loss of interest and complications. Priapism(six patients, 3.8%), pain(six patients, 3.8%) and granuloma on injection site(one patient, 0.6%) were noticeable complications, but coporal fibrosis and systemic side effect were not noticed. In conclusion, Trimix intracavernosal injection therapy is minimally invasive, simple, relatively safe and, most of all, very effective method for the treatment of the patients with erectile dysfunctions.

OBJECTIVE: Lethality of the chosen method during a suicide attempt is a strong risk factor for completion of suicide. We examined whether annual changes in the pattern of suicide methods is related to annual changes in suicide rates among older adults in South Korea and Japan. METHODS: We analyzed annual the World Health Organization data on rates and methods of suicide from 2000 to 2011 in South Korea and Japan. RESULTS: For Korean older adults, there was a significant positive correlation between suicide rate and the rate of hanging or the rate of jumping, and a significant negative correlation between suicide rate and the rate of poisoning. Among older adults in Japan, annual changes in the suicide rate and the pattern of suicide methods were less conspicuous, and no correlation was found between them. CONCLUSION: The results of the present study suggest that the increasing use of lethal suicide methods has contributed to the rise in suicide rates among older adults in South Korea. Targeted efforts to reduce the social acceptability and accessibility of lethal suicide methods might lead to lower suicide rate among older adults in South Korea.

Cerebral dural sinus thrombosis(CDST) has been described as a rare disease with a variety of patho-etiological factors. The diagnosis of CDST is difficult due to various symptoms and signs, none of which is specific to CDST. But timely diagosis is critical for effective management. The introduction and widespread use of computed tomography(CT), magnetic resonance imaging(MRI) and cerebral angiography made early diagnosis of CDST possible. In particular, MR venography is the most useful tool for establishing a correct diagnosis quickly. In early literature, mortality ranked between 30% and 50% but in more recent series it is between 5.5% and 30%. With the advent of diagnostic and therapeutic tools, early diagnosis and proper management has made the prognosis better. The appropriate therapy for CDST, however, has been the subject of much cortroversy. Individual variations of the venous system and collateral vessels are key factors to decide the proper treatment. In this report, we present two cases with symptomatic CDST treated without open surgical or direct endovascular interventions with good outcome.

PURPOSE: To analyze the improvement of symptoms and signs of dry eye after surgical punctual occlusion and to evaluate the effects of secondary systemic disease in dry eye patients. METHODS: From March 2011 to July 2014, 15 eyes of 8 dry eye patients with a history of punctal plug insertion underwent surgical punctal occlusion. Schirmer test was measured based on mean 2.9 mm. The patients consisted of 4 dry eye patients with Sjogren's disease, 1 with rheumatoid arthritis, 1 with graft-versus-host disease (GVHD), and 2 with no secondary systemic disease. Preoperative and postoperative ophthalmic examinations of log MAR visual acuity, subjective symptoms, corneal staining (National Eye Institute [NEI] score), and tear break-up time (BUT) were performed and the effects of secondary systemic disease in dry eye patients were evaluated. The results of surgical punctual occlusion were analyzed. RESULTS: All patients showed a statistically significant improvement of log MAR visual acuity, subjective symptoms, corneal staining (NEI score), and tear BUT. The patients with rheumatoid-related diseases showed improved symptoms after surgery, but the patient with GVHD showed no significant improvement after surgery. Among the study patients, 80.0% showed completely closed punctum and 20.0% showed partial recanalization. CONCLUSIONS: Surgical punctal occlusion is an effective alternative in patients with severe aqueous deficient dry eye who show recurrent punctal plug loss or complications associated with punctal plugs.

OBJECTIVE: In applying Electro-Convulsive Therapy(ECT) to patients, initial electric stimuli have been often determined without the adequate guidelines. This study was designed to determine adequate numerical value of parameters for initial electric stimuli inducing seizure successfully in ECT. We prepared Asan Medical Center(AMC) guidelines for 4 parameters based on our clinical experiences and MECTA(Monitored Electro-Convulsive Therapy Apparatus, MECTA Crop(R)) instruction manual, and investigated the success rate in the first session of ECT following AMC guidelines for parameters. METHOD: Twenty-two patients(male 10, female 12) treated with ECT using MECTA SR-1 model in Asan Medical Center between september 1996 and october 1998 were included in this study. We carried out bilateral ECT under anesthesia according to AMC guidelines. Seizure that persisted longer than 20 seconds was considered successful. RESULTS: 18 of 22 patients showed successful seizures in the first session (82%). Four patients failed to show successful seizures. One out of the foiled patients received inadequate stimuli due to premature release of switch burton and two patients were taking continuously anticonvulsants and anxiolytics, respectively prior to ECT. But all foiled patients except one, who was thought to have unusually high seizure threshold, demonstrated successful seizures in the second session with the same initial parameters. CONCLUSIONS: The bilateral ECT according to AMC guidelines resulted in the adequate seizures in all patients except one patient who had unusually high seizure threshold. These data show that AMC guidelines can be successfully applied in ECT using MECTA device.

OBJECTIVE: Gene expression of nm23 has been investigated in a number of tumors, including breast cancer, colon cancer, malignant melanoma, and hepatocellular carcinoma. Its down-regulation has been shown to be associated with metastasis or disease progression in some of the tumors. This study was carried out to define the relationship between nm23 protein expression and clinicopathological variables. METHODS: nm23 protein levels were investigated in 64 surgically resected specimens of stage III gastric cancer by immunohistochemical method, and association with clinicopathological parameters and survival rates were determined. RESULTS: The overall expression rates of nm23 was 68.7 %. There was no significant difference between nm23 protein expression and clinicopathological variables such as age, sex, stage, histology, tumor depth, number of metastatic nodes, tumor size, site and method of operation. Statistically, no significant differences between nm23 protein expression and overall survival rates were found. CONCLUSIONS: These results suggest that nm23 protein expression is an unsatisfactory prognostic indicator in stage III gastric adenocarcinoma.
