Recently with the development in computer technology and its communication system, many changes have come to the medical field. For example, Picture Archiving and Communication System(PACS) has been used in the medicine experimentally. But this system needs high cost and instrument, so this system is not used in personal generally. Our hospital established the medical forum for health and medical counseling in Computer communication network called HITEL. We analysed the questions about urologic problem especially from Sep, 1994 to Jan, 1997. Most of questions are related to external genitalia and sexually transmitted diseases and most of users were in their 2nd, 3rd and 4th decades and male-predominant. In conclusion, medical counseling using PC communication is an effective method especially in urologic field.

Current therapeutic approaches for presbyphonia are generally categorized into non-invasive and surgical methods. Voice therapy is commonly chosen as initial treatment modality used to reduce maladaptive compensatory muscle behavior and to improve glottal closure. Nevertheless, in advanced cases of presbyphonia, glottal insufficiency may be aggravated, reducing the benefits of voice therapy. To manage the glottal insufficiency observed in such cases, surgical intervention is performed to medialize the vocal folds. Available surgical modalities include injection laryngoplasty and type I thyroplasty. Additionally, cutting-edge regenerative treatments, such as the injection of basic fibroblast growth factor, are under investigation internationally and show promising outcomes. This review aims to elucidate the current indications and relevance of surgical interventions for presbylarynx.

OBJECTIVES: To investigate the effects of KCl on regulation of circadian gene CLOCK expression, we observed whether induction of CLOCK is influenced by KCl depolarization in B35 rat neuroblastoma cells. METHODS: B35 rat neuroblastoma cells were grown in Dulbecco's modified Eagle's medium supplemented with 10% FBS and 1% penicillin-streptomycin in a 37 degrees C humidified incubator with 5% CO2. Inhibitors including cycloheximide and actinomycin D were pretreated 1 hour before treatment with 50mM KCl. Immunoblotting with anti-CLOCK antibody was done. RESULTS: CLCOK is induced by 50 mM KCl in B35 Rat Neuroblastoma cells, and a maximal induction in CLOCK level reached peak at 8 to 20 hours. The pretreatment of cycloheximide and actinomycin D prevented the induction of CLOCK by 50 mM KCl. CONCLUSION: We suggest that KCl depolarization may play critical roles in several aspects of the circadian gene CLOCK expression.

An aneurysm of the distal superior cerebellar artery (SCA) is a highly rare disease. Fusiform aneurysms of the distal SCA are particularly challenging to treat. Clipping, trapping with or without bypass using microsurgery or endovascular treatment (EVT) were used to treat this condition. We describe the case of fusiform distal SCA aneurysms treated successfully with endovascular coiling with a 3-month follow-up. A 39 year-old male was presented with subarachnoid hemorrhage (SAH) and a 15 mm fusiform aneurysm of the ambient segment of the left distal SCA. EVT for parent artery occlusion and packing of the aneurysm was done. Left sixth nerve palsy appeared after 1 day of EVT. The symptom completely recovered within 1 week of the post-procedural period. No neurological deficit was seen during the clinical 3-month follow-up. EVT of fusiform distal SCA aneurysms with coils is a safe and feasible option to manage this rare condition. However, the treatment options must be carefully selected depending on the neurologic condition, development of collateral circulation, and configuration of the dissection.

OBJECTIVE: This study is to report our experience of 40 cases of spinal schwannoma. METHODS: From 1995 to 2006, medical records were retrospectively reviewed in 40 cases of spinal schwannoma. RESULTS:We treated 40 spinal schwannomas in 38 (22 male and 16 female) patients. The mean age was 50.2. Four cases were sited in the cervical spine, 11 cases in the thoracic spine, and 25 cases in the lumbar spine. Two patients showed recurrences. Thirty-eight cases were intradural-extramedullary type and 2 cases were extradural. Two cases (5%) including 1 recurred case had no postoperative motor improvement. Ninety-five percents of patients improved on postoperative motor grade. CONCLUSION: Spinal schwannoma is mostly benign and extramedullary tumor. There were 2 recurred cases (5%) that had history of previous subtotal removal at first operation and had shown worse prognosis compared with the cases without recurrence. To reduce the recurrence of spinal schannoma, total excision of tumor mass should be done.

OBJECTIVES: The Korean government in January 2006 instigated an exemption policy for hospitalized children under the age of six years old. This study examines how this policy affected the utilization of medical care in Korea. METHODS: A total of 1,513,797 claim records from the Health Insurance Review Agency were analyzed by complete enumeration methods. The changes of medical utilization were compared from 2005 to 2006. In addition, the changes of medical utilization between 2004 and 2005 were compared as a pseudocontrol group. RESULTS: The admission rate increased 1.14-fold from 15.20% in 2004 to 17.32% in 2005, and this further increased 1.08-fold to 18.65% in 2006. The increase of patients with a common cold (1.2-fold) was higher than that of both the general patients (1.08-fold) and the patients with the top 10 fatal diseases (0.91-fold). The average length of stay per case for clinics showed the highest increase rates (1.06-fold). The rates of patients with the common cold showed a higher increase (1.05-fold) than that of the general patients. The average medical expense per case was increased by 1.10-fold from 2005 to 2006, which was higher than that from 2004 to 2005 (1.04-fold). The increase rate for patients with the common cold was higher at 1.18-fold than that of the general patients. CONCLUSIONS: The cost exemption policy has especially led to an increase in the utilization of clinics and the utilization by patients with a common cold.
