Apocrine sweat gland carcinoma is a very unusual malignant skin adnexal tumor and mostly occurs in areas where apocrine elands are abundant namely. axilla. upper arm. scalp. eyelid. vulva and external auditory meatus. The scrotal location is not yet reported. We report a case of apocrine sweat gland carcinoma of scrotum in a man aged 85, which was managed by local excision. The histologic finding is that of poorly differentiated adenocarcinoma. Evidence of decapitation secretion typical or apocrine glands. is present in some areas.

BACKGROUND: Prostaglandin system is known to participate in manifestation of the renin-angiotensin system. However, role of prostaglandins on the renin-angiotensin system in development of hypertension is not well established. This study was to examine whether the role of prostaglandins is altered in experimental hypertension. METHODS: Two-kidney, one-clip(2KIC) renal hypertension was made by clipping the left renal artery with a silver clip(internal gap of 0.2mm) and deoxycorticosterone acetate (DOCA)-salt hypertension by subcutaneous implantation of DOCA(200mg/kg) strip plus saline(1%) drinking. They were used 3 weeks later. Age-matched normal rats served as a control. Femoral artery was cannulated and arterial blood pressure and heart rate were monitored continuously. RESULTS: 1) In normotensive rats, saralasin infusion(20 microg/kg/min, IV) caused a decrease in mean arterial pressure without significant alterations in heart rate. Indomethacin-pretreatment(10mg/kg, IP) abolished the depressor response to saralasin. 2) The depressor response to saralasin was more marked in renal hypertensive rats than in normotensive rats. The magnitude of maximum decrease in blood pressure, however, was comparable between the hypertensive and normotensive rats. Indomethacin-pretreatment did not affect the depressor response to saralasin in renal hypertensive rats. 3) In DOCA-salt hypertensive rats, saralasin infusion rather caused an increase in mean arterial pressure without significant alterations in heart rate. The pressor response to saralasin was not affected by indomethacin-pretreatment. CONCLUSION: These results indicate that prostaglandin system may modify renin-angiotensin system in normotensive rats. It is suggested that mechanisms other than prostaglandin system participate in the full-blown manifestation of renin-angiotensin system in 2KIC renal hypertensive rats.

To build and to manipulate clinical data in one of the important works in the hospital. In order to accurately append the data and to quickly find and display the informations as the user need, we developed a software program running on the personal computer. Our system largely consists of four parts; registration of the clinical and departmental data, retrieving tool of articles in the medical journal, collection of special data for clinical survey and display system of the various reports. In our experiences, we consider the key factors for systemic management of clinical rearch data base as the follows; work analysis for data processing, design of data base, coding and classification of basic data and technique of registeration. Of these standarized coding system of the orthopedic diseases appeare to be of it most importance.

BACKGROUND: Kurt Semm, a German gynecologist, was first to describe a laparoscopic appendectomy for an incidental appendectomy in gynecologic surgery. At that time, it was limited to an incidental appendectomy performed during gynecologic surgery. The development of laparoscopic instruments and more experience has allowed surgeons to perform laparoscopic surgery easier than before. Nowadays, laparoscopy allows surgeons to perform appendectomies in a safe and effective way, and it reduces the risk of performing unnecessary appendectomies. METHODS: We reviewed the records of 201 patients who had an appendectomy at our hospital from February 1997 to December 1997. A laparoscopic appendectomy was carried out in 51 cases, and an open appendectomy was carried out in the others. RESULTS: 1) There was not a significant difference between the two groups in regard to age and sex. The male-to-female ratios were 1.32:1 in laparoscopic appendectomy group and 1.17:1 in the open appendectomy group. The mean ages were 30.3 years in laparoscopic appendectomy group and 29.7 years in open appendectomy group. 2) There was not a significant difference in pathologic severity between the two groups. The majority had suppurative appendicitis in both groups. Postoperative complications were less frequent in the open appendectomy group. 3) The mean operative times were 55.6 minutes in the laparoscopic appendectomy group and 42 minutes in the open appendectomy group. 4) The mean hospital stays were 4.69 days in the laparoscopic appendectomy group and 6.96 days in the open appendectomy group. 5) The mean postoperative periods until normal activity were 8.79 days in the laparoscopic appendectomy group and 12.85 days in the open appendectomy group. 6) The postoperative use of analgesics was less frequent in the laparoscopic appendectomy group. 7) Conversion to an open laparotomy occurred in 3 cases. CONCLUSIONS: We think that a laparoscopic appendectomy is a safer, more effective, more cosmetic, and less invasive procedure than an open appendectomy.

PURPOSE: Circumcision is widely practiced in Korea. Circumcision has been popularly performed with mechanical devices such as the Gomco clamp, the Plastibell device and other modified devices. We investigate the effect of using a new device (the circumcision clamp). MATERIALS AND METHODS: We conducted a retrospective study between December 2003 and February 2004 on 75 patients who wanted circumcision. 25 patients were operated on by performing conventional circumcision, and 50 patients were operated on by using the circumcision clamp. RESULTS: The mean operation time for the new device group was shorter than that for the conventional circumcision group (p<0.05). No significant difference of complications was noted between the conventional circumcision group and the circumcision clamp group. CONCLUSIONS: The new method with using the circumcision clamp has a benefit as it is designed to expose the glans and it saves operating time.

Various remedies have been developed for broad damage to soft tissue in limbs by traffic accidents and mechanical mishaps that have greatly increased in modern society. If the damaged part is trivial, it may be generally treated with local flap or skin graft. However, this has been limited by the ability to choose the flap available depending on the condition of the wounded part, so that, if it is rather large or severly inflamed, or if it occurred with a bone-fracture, it is inevitable to practice the free flap. In the past, the focus was on whether the free flap would survive or not. However, the function of donor the and recipient, as well as the problem of aesthetic appearance, gas become a matter of increqsing interest and concern as the survival rate of the flap has greatly improved due to the development of precise operations. In thes study, therefore, some complications were analyzed which may develop in a donor by a variety of free flaps. Preoperative plans, as well as intraoperative and postoperati-ve treatment were also studied to minimize the cause of complications. To investigate these questions, we undertook a clinical analysis of 91 followed patients from 1990 to 1997. There were 68 male and 23 female patients ranging in age from 6 to 67 years, with an average of 34.7 years. The length of follow-up ranged from 8 months to 6 years. The results of this study were as follows: Sufficient plans must be made on the donor before operation, single textures like muscle or fascia should be used if possible, and incision should be arranged along Langer`s line. Some measures to reduce wound tension should be pursued, and plans must be made to immobilize the site for an ample period after the operation. Some precautious should also be considered during the operation, such as avoiding traction surrounding nerves and vessels, preserving paratenon, practicing osteotomy with great care and properly stopping any bleeding. In addition, formation of a hematoma or seroma should be preventcd and the donor must be sutur-ed as soon as possible to reduce infection. With the application of the basic operational principles on the treatment of donors, the complications which might be caused by each free flap can be reduced, and furthermore, be protected against.

PURPOSE : Lung cancer is the leading cause of cancer death in the world, including Korea. The aim of this study was to investigate the clinical features of the lung cancer patients who were seen in a University hospital between 1994 to 1998. MATERIALS AND METHODS : We performed a retrospective review of lung cancer clinical information at Kosin University Gospel Hospital from 1994 to 1998. We analyzed the age, gender, pathologic types, treatment methods and survival. RESULTS : Among 1,547 patients, 1,232 patients (79.6%) were male. The age distribution ranged from 20 to 84 years, and the mean age was 60.2 years old. Squamous cell carcinoma was the most common type of lung cancer (39.7%), followed by adenocarcinoma (23.1%), and small cell carcinoma (16.4%). However, there was an increasing incidence of adenocarcinoma every year. The stages at the diagnosis were I : 6.6%, II : 6%, III : 45.6% and IV : 41.8%. For the small cell carcinoma, 44.6% of the patients were in a limited stage and 55.4% were in an extensive stage. The initial treatments included chemotherapy (46.5%), surgery (15.1%) and radiotherapy (5.1%), but 32.2% of the patients received supportive care only. For the cases receiving surgery, the 5 year survival rate for the stage I patients was 66%, that for the stage II patients was 43.2% and that for the stage III patients was 11.8%. The median survival time (MST) for patients who underwent surgery plus adjuvant chemotherapy was 3.22 year, but the MST of the surgery-treated only patients was 1.51 years. So, adjuvant chemotherapy prolonged survival (p=0.000). On the subgroup analysis, young age and female lung cancer patients who did not receive adjuvant chemotherapy showed poor survival. CONCLUSION : Squamous cell carcinoma was the most common type of lung cancer. The active treatments were important for the patients' prognosis. For the patients receiving surgery, adjuvant chemotherapy had a role in improving survival and especially for young age and female lung cancer patients
