The increasing use of intravenous polyethylene catheters has led to a growing incidence of accidental catheter breakage and migration of fragments into the central vascular system usually in the inferior vena cave, the right atrium, of the pulmonary artery. The most common complications were formation of a thrombus in the area of the foreign body, infection with endocarditis, and perforation of the heart. And so obviously the polyethylene catheter must be removed. In 1967, Massumi and Ross et al have been successful in removing a catheter fragment from the right atrum percutaneously with a snare device. With some modification as suggested by Curry, method of retrieving fragments of polyethylene catheters from the heart without chest surgery utilize wire snares or endoscopic forceps. This report describe the technique and its use in successfully managing these complications in four consecutive cases.

Androgen acts via the androgen receptor and can play a critical role in the development and growth of the prostate and the pathophysiology of prostatic diseases. Testosterone is the most abundant circulating androgen and is converted to dihydrotestosterone (DHT), a more potent androgen, by steroid 5alpha-reductase. There are two 5alpha-reductase isoenzymes, type 1 and type 2, in humans and animals. Type 2 5alpha-reductase predominates in the prostate. While deficiency of type 2 5alpha-reductase causes male pseudohermaphroditism, increased DHT has been implicated in benign prostatic hyperplasia and prostate cancer. The aim of this article is to highlight the significance of 5alpha-reductase in the development and growth of the prostate and pathogenesis of prostatic diseases.

We report a case of angiosarcoma of the face and scalp in a 76-year-old man. Immunochemical staining with factor 8-related antigen and ultrastructural find ings confirm that this tumor was origined from endothelium. The patient had a good initial response to treatment with radiotherapy.

To observed whether the specific IgG antibody test using ELISA was useful in diagnosis of presently ill patients of paragonimiasis, a total of 95 sera were tested. The sera were collected from 21 egg positive cases, 8 from positive reactors of intradermal test, 7 from Clonorchis infected, 9 from other parasitic diseases and 50 from apparently non-infected cases. By the result, the sensitivity of the test was 86% and the specificity was 100%. There were no cross reactions between Paragonimus antigen and other parastic infections. Specific IgG antibody test by micro-ELISA was concluded to be useful for mass screening of the presently ill paragonimiasis in the field.

Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

BACKGROUND: As the pleural inflammation progresses, exudative pleural fluid becomes loculated rapidly with pleural thickening. Complete drainage is important 13 prevent pleural fibrosis, entrapment and depression of lung function Intrapleural urokinase instillation therapy has been advocated as a method to facilitate drainage of gelatinous pleural fluid and to allow enzymatic debriment of pleural surface. This study was designed to investigate the Predictors of effeotiveness of intrapleural urokinase in treatment of loculated pleural effusion METHOD: Thirty-five patients received a single radiographically guided pig-tail catheter ranging in size from 10 to 12 French Twenty-two patients had tuberculous pleural effusions, and 13 had non-tuberculous postpneumonic empyemas. A total of 240,000 units of urokinase was dissolved in 240 ml of normal saline and the aliquots of 80mL was instilled into the pleura1 cavity via pig-tail catheter per every 8hr. Effectiveness of intrapleural urokinase instillation therapy was assessed by biochemical markers, ultrasonography, and technical details. A greater than 50% improvement on follow-up chest radiographs was defined as success group. RESULT: Twenty-seven of 35 (77.1%) patients had successful outcome to urokinase instillation therapy. Duration of symptoms before admission was shorter in sucess group (11.8α6.9day) than in failure group (26.62α16.5day) (P<0.05). Amount of drained fluid during urokinsse therapy was larger in success group (917.1α392.7ml) than in failure group (613.8α259.7ml) (P<0.05). Pleural fluid glucose was higher in success group (89.7 α35.9mg/dl) than in failure group (41.2α47.1mg/dl) (P<0.05). Pleural fluid LDH was lower in success group (878.4α654.31U/L) than in failure group (2711.1α973.1IU/L) (P<0.05). Honeycomb septated pattern on chest ultrasonography was observed in six of eight failure group, but none of success group(P<0.05). CONCLUSION: Longer duration of symptoms before admission smaller amount of drained fluid during urokinase therapy, lower glucose value, higher LDH value in pleural fluid examination and honeycomb septation pattern on chest ultrasonography were predictors for failure group of intrapleural urokinase instillation therapy.
