OBJECTIVE: To report the pregnancy which was made by in vitro fertilization using recombinant follicle stimulating hormone and gonadotropin releasing hormone antagonist. MATERIAL AND METHOD: Case report. RESULTS: Six oocytes were retrieved and all were fertilized by intracytoplasmic sperm injection. Six embryos were transferred and the pregnancy was confirmed. CONCLUSION: It is envisaged that the availability of recombinant gonadotropins and gonadotropin releasing hormone antagonists will ultimately lead to shorter, cheaper and safer treatments, using reduced dosages.

PURPOSE: To determine the radiographic findings which predict the presence of nonbronchial systemic feeding arteries (NBFAs) in patients undergoing embolotherapy to control hemoptysis. MATERIALS AND METHODS: In 48 patients (39 men and 9 women; mean age, 51 years) who underwent embolotherapeutic procedures for controlling hemoptysis, selective angiography was performed at the intercostal, subclavian and bronchial arteries in 65 hemithoraces (right 11, left 20, bilateral 17). Underlying diseases were tuberculosis (n=34, including three patients with aspergilloma), bronchiectasis (n=11), paragonimiasis(n=2) and metastatic cancer (n=1). The presence of NBFA at angiography was correlated with radiographic findings including pleural thickening, parenchymal distortion, and the location of lung lesions. RESULTS: NBFAs were found in 34 (77%) of 44 hemithoraces with pleural thickening, and in six (29%) of 21 without pleural thickening; the sensitivity and specificity of prediction were 85% and 60%, respectively. NBFAs were observed with greater frequency as the thickness of the pleura increased, and the extent of pleural thickening correlated less with the presence of NBFA than did thickness. NBFAs were found in 35 (78%) of 45 hemithoraces with parenchymal distortion, and in five (25%) of 20 without distortion (p<0.001). In addition, the distribution of the underlying disease in the upper lung zone showed close correlation with the presence of NBFAs (p<0.05). CONCLUSION: In patients with hemoptysis, the pleural thickening revealed by radiography has a high sensitivity and a relatively low specificity for predicting the presence of NBFA, and patients with parenchymal distortion and upper lung lesions have a high incidence of NBFA.

Rhabdomyosarcoma are reportedly the most common soft tissue sarcoma occuring in childhood, but the biliary tree is a rare site of origin for this tumor. Recently we experienced a case of embryonal rhabdomyosarcoma of the biliary tree in a 30-month-old child. UItrasonography showed hypoechoic mass filling the dilated left. intrahepatic & extrahepatic bile ducts, and CT showed hypodense mass with heterogeneous enhancement after contrast infusion. Intraoperative cholangiography showed filling defects within the dilated left. intrahepatic & extrahepatic bile ducts. Postoperative MRI showed residual mass within the left. intrahepatic duct which was hypointense on T1WI and hyperintense on T2WI.

The authors retrospectively reviewed the high resolution computed tomographic scans of 19 patients who had hematogenous or lymphangitic metastatic lung lesions. In all patients, the histologic diagnosis for primary cancers and the radiographic manifestations of pulmonary metastasis were established. Certain characteristic findings of metastatic lung tumors on HRCT scans were evident: uneven thickening of bronchovascular bundles, multiple small nodules, thickening of interlobular septum, and the presence of polygonal lines. The nodules are more predominent in hematogenous metastasis. The prevalent site of nodules is cortical portion of lung.

To evaluate the historical trend of anesthetic experience for the past 22 years a total of 68,473 cases which were performed at the National Medical Center from 1959 to 1981 were studied. To simplify the analysis statistically, the author selected the anesthetic cases every other year(12 years). 1) General anesthesia was performed in more than 78% of the total cases and of this number endotracheal intubation has been used with increasing frequency(average 92.8%). 2) For intravenous induction, thiopental sodium was used as the main agent, in more than 90% since 1980. 3) Trichlorethylene, cyclopropane and ethylchloride which had been used since 1961, were abandoned from 1978 except for training purposes. Methoxyflurane was used from 1973 to 1979, but given up there after because of it's nephrotoxicity. The use of halothane has steadily increased(86% of the total inhalation anesthetics) and ethrane has also been used with increasing frequency since 1980. 4) Pancuronium has been used as a primary muscle relaxant instead of gallamine and D-tubocurarine which had been used as the main durgs from 1959 till 1979. 5) Innovar and morphine as intravenous anesthetics, have recently been with increasing grequency.

Total vitrectomy and removal of the posterior hyaloid membrane were done in 7 patients who were diagnosed as macular hole with specific causative factors. The causative factor of 2 patients is high myopia and of remainers is trauma. Of the 7 patients treated by removal of the posterior hyaloid membrane during total vitrectomy, 3 patients showed anatomical and functional success, 2 patients only the anatomical success, and 2 patients failure. The postoperative complications included phthisis bulbi, proliferative vitreoreinopathy, optic atrophy, and macular degeneration, and iatrogenic rhegmatogenous retinal detachment. Two patients of the 3 success cases complained of mild diplopia after operation.
