An increasing use of complementary and alternative medicine(CAM) is apparent both in Asian and in Western countries for the management of numerous diseases to improve symptoms and to improve general health and well being. Many patients with benign prostatitc hyperplasia(BPH) and lower urinary tract symptoms(LUTS), erectile dysfunction(ED), urinary tract infection(UTI) are using CAM. Complementary and alternative medicines for urologic malignancies such as renal cell carcinoma, bladder cancer, and prostate cancer are also one of the important issues in the management of patients. Dietary supplements and nutraceuticals are commonly used modality for the patients with BPH/LUTS or ED. Vegetables and cruciferous fruits showed significant preventive effect on urologic malignancies in many studies. Phytotherapy for BPH including beta-sitosterols, saw palmetto, pygeum, and nettles etc, is under vigorous research for their therapeutic effect. No solid evidence showing better effective treatment modality for ED than placebo was found yet in CAM area. Recently, a potent NO donor, L-arginine is under research with promising results. Cranberry juice has been used for the patients with recurrent UTI but safety was a limit for its use. Various antioxidants have been studied for prevention of urological malignancies. Lycopene, isoflavone, vitamin A, C, and E, and polyphenols showed the possibility of decreasing cancer incidence in many studies but their effect is still controversial. Vitamin D is known to be associated with cancer progression and the effect of combination treatment with other chemotherapeutic agents for advanced cancer is under trial. CAM is used by a number of patients with urological diseases and urologists need to have both accurate knowledge and apprehension of CAM. The possible effects and side effects should be defined and offered to the urologic patients by urologists.

With regard to various pathologic conditions, it is important to understand not only MR findings, which dependon the anatomic location of intraventricular lesions, but also the anatomic location most appropriate for surgicalintervention. In this paper we will analyze and demonstrate the incidence and characteristic MR findings ofvarious intraventricular tumors according to the location of ventricles.

The incidence of congenital unilateral renal hypoplasia is extremely rare.Two cases of congenital unilateral renal hypoplasia were presented with review of literature.

Fifty three surgically resected gallbladders(49 cases of chronic cholecystitis with or without cholelithiasis, 4 cases of incidentally resected gallbladders) and 14 autopsy cases were subjected to the histotopographic analysis to identify the nature and distribution of metaplastic mucosal changes, and to determine the possible histogenesis of these mucosal lesions and diagnostic implication as a parameter of chronic cholecystitis. 1) Antral type glands were demonstrated in 47(88.7%), goblet cells in 19(35.8%) and surface epithelial changes in 27(50.9%) of total surgical specimens, indicating the benign metaplastic changes of the gallbladder mucosa toward the gastric or intestinal type. 2) Topographic distribution illustrated the extension of antral type gland to the middle and upper one third portions of the gallbladder mucosa in 37 cases, each. Goblet cells in the middle and upper one third of the mucosa were demonstrable in 13 cases(68%) an 8 cases(42%), respectively. 3) Average age by degree of extension was 50.0 years in Grade O-I, 50.1 years in Grade II and 56.4 years in Grade III. 4) Among 53 surgically resected gallbladders, gallstone was found in 31 cases, in which was a significant correlation between the distribution of metaplastic changes by degree of extent and cholelithiasis. 5) There was no statistical significance between incidence of metaplastic changes of the gallbladder and degree of inflammatory reaction by means of chronic and/or acute inflammatory cell infiltration and Rokitansky-Aschoff sinus formation. 6) Only two out of fourteen autopsy cases demonstrated focal and spotty presence of goblect cells. It is of authors assumption that the lining epithelium of the gallbladder undergos various types of metaplastic changes in the diseased conditions, in which cholelithiasis is included as one of preceding factor. And also, the diagnostic implication of epithelial metaplasia as an expression of chronic cholecystitis is discussed.

Malignant hyperthermia is a dramatic syndrome that rarely arises during anesthesia and which is still fatal in the majority of cases. It is a hypermetabolic muscle condition characterized by hyperpyrexia and skeletal muscle rigidity. Any potent inhalation anesthetic agent or any skeletal muscle relaxant can trigger this acute catast rophic reaction. A case is presented of a 28 year old femal with a family history of malignant hyperthermia in herrelatives. She sunderwent repair of a retinal detachment under N2O-O2-halothane withcinduction by thiopenthal and succinylcholine. One and half hours after induction, arrhythmia developed and was followed by unstable blood pressure, hyperpyrexia, muscular rigidity. Anesthesia was ended and vigorous emergency treatment was attempted. But she died postoperatively on the 4th day after anesthesia. The etiologic factors, incidence, clinical feature, prevention, treatment and prognosis of malignant hyperthermia are discussed.

Cervical plexus block has been evaluated clinically for surgery of the anterior neck in 13 patients during the 10 months(from July 1981 to April 1982) at the Department of Anesthesiology in Capital Armed Forces General Hospital. We have assessed CPB for technique, onset, anesthetized area, duration, complication and supplimentary agents, and reviewed the anatomical aspects of cervical plexus. The distribution of injected local anesthetics was demonstrated under radiography using Urographin. We experienced incomplete block in 9 cases which needed substitution with Thalamonal. The incidence of complications was few and most significant complication seen in this study was respiratory difficulty. However, There was no evidence for phrenic nerve paralysis. Cervical plexus block was performed safely and effectively for surgery of the anterior neck.

Spindle cell carcinoma of the upper aerodigestive tract mucosa was usually presented as polypoid mass and shows squamous cell carcinoma or dysplasia in the surface and underlying spindle cell proliferation. The spindle cell area discloses a variable pattern of sarcoma including rare osteosarcoma of 0~20% incidence. The histogenetic origin of the spindle cell component is now considered a metaplasia of squamous cell carcinoma. We experienced a case of spindle cell carcinoma of larynx showing massive underlying bone formation with proliferation of osteoclast-like cells in 75 year-old man. The immunohistochemical study demonstrates positive reaction with cytokeratin in area of squamous cells and with vimentin in area of spindle cells and osteoclasts. There are very focal reactivity for high molecular weight cytokeratin in spindle cell area.

Though basal cell carcinoma is the most frequent and increasing malignant tumor of the skin in Korea, its pathological analysis has been done only on the small numbers. So, we did a comprehensive pathologic study on the 283 patients with basal cell carcinoma diagnosed in the Department of Pathology, Seoul National(233cases) and Chung-Ang(50cases) University Hospital during 1975-1992. The age distribution was ranged from 15 to 84 years with highest incidence rate in the age group of 5th-8th decades and 83.7% of all patients were over 40 years of age. Sex difference was not noted. The most common site was face occuring in 235 out of 283cases(83.0%) especially in the eyelid(25.5%), nose(17.9%) and cheek(16.6%). The most frequent histopathologic type was solid type(54.0%) followed by mixed(23.9%), adenoid(7.5%), and metatypical(4.7%). Among 51 mixed type, all showed solid components with adenoid(51.0%) followed by morphea(25.5%) and metatypical type(13.7%). And among 14 recurrent cases, solid type is found in 50% of cases. The characteristic clinicopathological findings are solid arrangement of tumor cells with various histological pattern and predominant occurence on the face.
