Cryptococcus albidus, a non-neoformans species of the genus Cryptococcus, is generally regarded as a rare cause of disease. There have been only 14 previously reported cases in which this organism has been isolated as a pathogen, none of which occurred in a renal transplant recipient. A 23-year-old renal transplant recipient taking medication consisting of cyclosporine and prednisolone was admitted with a 10-day history of dry cough, fever and progressive dyspnea. The next day, his respiratory status deteriorated dramatically, and he developed acute respiratory distress syndrome (ARDS) and fulminant septic shock. On the eighth hospital day, tender macules on both his shins coalesced to form erythematous patches. Cryptococcus albidus was isolated by skin biopsy and tissue culture. We report here the first case of disseminated cryptococcosis caused by C. albidus in a renal transplant recipient who had been successfully treated with fluconazole monotherapy.

Wilms' tumor is the most common malignant abdominal tumor in the adolescent and pediatric period, whereas adult Wilms' tumor is uncommon. Wilms' tumor often originates in the kidney. Extrarenal Wilms' tumor is rare and has been considered "unstageable". Therefore, treatment and long-term survival have not been uniformly reported. We report a 24 year-old female who developed extrarenal Wilms' tumor, in the retroperitoneal space. She was misdiagnosed for ovarian neoplasm and underwent debulking operation, by which Wilms' tumor was confirmed. Palliative chemotherapy and radiotherapy were performed.

Omental leiomyosarcomas are rare intra-abdominal tumors. This report describes a case of primary leiomyosarcoma of the greater omentum. A 76-year-old female complained of palpable abdominal mass which was revealed to be a primary omental tumor by means of UGI, small bowel series, abdominal ultrasonography, and computed tomography. Upon laparotomy, no metastatic focus was found and a part of tumor was found adhered to gastric serosa. Total omentectomy including the mass was performed. Histological examinations of the tumor confirmed a diagnosis of leiomyosarcoma. At 36 months postoperatively, there is no sign of tumor recurrence or metastasis.

Spindle cell carcinoma of the esophagus containing both carcinomatous and sarcomatous elements is rare, accounting for approximately 1- 2% of all esophageal neoplasms. Terms used to describe this lesion include carcinosarcoma, pseudosarcoma, polypoid carcinoma, pseudosarcomatous squamous cell carcinoma and spindle cell variant of squamous cell carcinoma. Spindle cell carcinomas were originally classified as carcinosarcomas or pseu- dosarcomas, depending on the morphology and bilologic behavior of the particular lesian. However, pseudosarcoma and carcinosarcoma appear to be the same pathologic entity with varying degrees of anaplastic spindle cell metaplasia of the carcinomatous portion of the tumor. Thus, these lesions have been clsssified together as spindle cell carcinomas. A 59 year-old man who experienced weight loss for 4 months was hospitalized as a result of suffering from dysphagia for 2 months. A diffuse bulky protruding mass with superficial ulceration and easy friability on 25 to 35 cm from the incisors, which invaded the right intermediate bronchus and involved the right paratracheal and subcarnial lymph nodes, were obsetved in esophagogram, endoscopy and chest CT. Pathologic finding, including immunoreactivity to cytokeratin and vimentin, was consistent with spindle cell carcinoma. We report a case of spindle cell carcinoma of the esophagus.

Esophagea1 achalasia is a disease of unkown etiology characterized by abscenee of peristalsis in the body of the esophagus and failure of the lower esaphageal sphincter to relax in response to swallow. The cause has been suggested by the lack or abscence of ganglion cell in Auerbach's plexus. About 10% of patients with achalasis develop pulmonary complication such as aspiration pnuemonia, pulmonary fibrosis, pulmonary tuberculosis, culosis, bronchiectasis, lung abscess and bronchial asthma. Although aspiration pneumonia is the most common pulmonary complication in patients with achalasia, lung abscess is the extremely rare complication. A 48 years old female, who has experienced dysphagia and regurgitation for several years, is hospitalized because of high fever, cough and sputurn for 2 weeks. Lung abscess in apicoposterior segment of left upper lobe is observed in X-ray and chest CT. The findings of esophagogram, esophagogastroscopy and esophageal manometry are consistent with achalasia. We report a case of lung abscess associated with achalasia.

A study for seroprevalence of Hepatitis B virus markers (HBsAg, Anti-HBs, HBeAg and Anti-HBe) by EIA method and the Liver Function Test(SGOT and SGPT) using kinetic method was carried :out from January; to October 1995 :among male workers of a .major iron and steel manufacturing company, located,,in Pohang. The results were as follows; 1. The distribution of hepatitis B virus markers showed that the proportions of HBsAg(+)/Anti-HBs (-), HBsAg(-)/Anti-HBs (+) 'and HBsAg(+)/Anti-HBs (+) were 8.1%, 60.5% and 0.1%, respectively. The positive rate of HBsAg in all subjects was 8.2% whereas that of anti-HBs was 60.6%. 2. The proportions of HBsAg(+)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) increased significantly with age. While the distribution of hepatitis B virus markers exhibited no significant differences among the groups classified by educational background or work type. 3. The proportion of drinkers in HBsAg (+)/Anti-HBs (-) (73; 9%) was significantly lower than those of HBsAg (-)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (+) (84.6% and 85.7% respectively). The proportions of smoking for the three groups of HBsAg (-)/Anti-HBs(+),-HBsAg (+)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (-) were 54.3%, 53.7% and 53.0%, respectively (p<0.01). The proportion of the subjects with abnormal liver function test in HBsAg (+)/Anti-HBs (-) was 40.1%, whereas those in HBsAg (-)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) were 21.9% and 18.4%, respectively. 4. The distribution of e Ag markers among HBsAg (+) subjects showed that the proportions of HBeAg(+)/Anti-HBe(-), HBeAg(-)/Anti-HBe(+) and HBeAg(+)/Anti-HBe(+) were 31.3%, 55.0% and 1.6%, respectively. The proportion of HBeAg(+)/Anti-HBe(-) decreased significantly with age and those of HBeAg(-)/Anti-HBe(-) and HBeAg(-)/Anti-HBe(+) increased with age. The positive rate of HBeAg among HBsAg (+) subjects was 32.9%. In conclusion, as a screening method, EIA is. recommended to test hepatitis B virus markers, especially when examining Anti-HBs more sensitively. For the workers of the iron and steel manufacturing company studied, liver diseases caused by other than hepatitis B should be given a special care including an education avoiding alcohol drinking.

Primary malignant melanoma of vagina is a rare tumor which is easily misinterpretated in routine cytologic examination. We lately experienced a case of primary malignant melanoma of the vagina with direct cervical extension diagnosed by Pap smear. The cervicovaginal smear showed variable sized clusters of epithelial cells or singly scattered abnormal epithelial cells. Most of the tumor cells had round hyperchromatic nuclei with prominent nucleoli and brownish pigments in cytoplasm. The cytologic findings are compared with histologic features of resected specimen.

POSCO Health Care Center has collected health and environmental data using computerized system since 1987. One of the important roles of Industrial Health Care Center is to provide a comprehensive occupational health care, including therapeutic medical care, periodic medical examination and industrial hygiene control for the prevention of work-related illness. To strengthen the functions of an occupational health surveillance system since May, 1992, and it is scheduled to be completed by March, 1994. The modified POSCO Computerized Occupational Health Surveillance System (PCOHESS) contains three major area: health care, environmental monitoring, and personal information. The linkage among three area, lacking in the previous system, was emphasized in PCOHESS. The area of health care assists the management of preplacement examination data as well as the diseased and disabled data, and it will facilitate the preplacement for new employees and will enable an efficient care for the diseased and disabled. Environmental and personal sampling data, and personal information data, such as age, education and jobcode etc, that are linked to each employees, can assist the health care professionals to decide the type and time of medical examination and to periodically supply proper protectors. Data collected from the time of one's employment until his/her retirement can be used for the epidemiologic surveillance which will enable to evaluate the employee's health status related to his/her work environments, and to indentify the places that are necessary to be improved.
