Small cell carcinoma of the ovary has been identified as a specific histopathologic entity. The first II cases were reported by Dickersin et a1, 1982, Since then only 80 cases were reported in literature. This rare and highly aggresive melignancy primarily affeets ehildren and young women(10-40) and grows rapidly, with hypercalcemia occuring frequently. Abscence of effective treatment results in early mortality. Recently we have experienced one case of primary sma11 cell carcinoma of the ovary, which is presented with a brief review of the literature.

Rosai-Dorfman disease is a rare histiocytic disorder, clinically characterized by massive, bilateral painless cervical lymphadenopathy with potential for extranodal manifestations. We report a 45-year-old male patient who presented with a slowly growing erythematous nodule of the left chin. The mass appeared non-vascular on computed tomography study, but ultrasonogram was suggestive of a vascular lesion. The lesion was excised with presumptive diagnosis of a hemangioma. However, histopathologic examination of the surgical biopsy revealed histiocytic infiltration with emperipolesis, which was pathognomic for Rosai-Dorfman disease. Additional imaging studies did not reveal lymph node enlargement or other extranodal manifestation. The patient was diagnosed with cutaneous form of the Rosai-Dorfman disease and was discharged home. He remains free of local recurrence at 8 months.

The ischemic coitis proximal to obstructive colon cancer was firstly reported by MacCallum and Kaisch in 1947. Nowsdays, its clinical importance and the study of pathogenesis is reported frequently. Because of the rare inciedence of this complicated condition this lesion could be overlooked which then could result anastomotic leakage, fecal fistula and peritonitis. Recently, we have examined a 61 year-old Korean male patient who had the complaints of acute abdominal pain and bloody diarrhea. The diagnosis of gangrenous ischemic colitis associated with obstucting rectal cancer was confirmed on the basis of sigmoidoscopic and operative and associated histopathological findings. After prompt surgical intervention, the patient was discharged with good improvement. The literatures are reviewed here with the case presentation.

Measurement of peak flow rate (PER) is useful to assess venilatory capacity of a critically ill patient and particulary in the evaluation of obstructive ventilatory disease because of it easy management. A number of studies have already shown the usefulness of PFR measurement for rapid determination of pumonary reserve, for preoperative assement of pulmonary function or in evaluating changes in patient's degree of pulmonary disability. In view of the close correlation between PFR & MBC(Maximal breathing capacity) peak flow determination should also be of value in patients in whom the MBC cannot be measured easily because of the patient's illness or lack of sustained cooperation. In this study, the correlation coefficient (r) was found to be 0.77 between PFR & MBC, 0.72 between PFR & FEV1(forced expiratory volume for one second) and 0.73 between PFR & VC(vital capacity). Therefore we think that the measurement of peak flow rate in detecting ventilatory disease or in following a patient's ventilatory capacity is recommended.

Clear cell sarcoma of kidney is highly malignant tumor that tends to occur in young infants, and has a tendency to metastasize to the bone. Our review of the literature disclosed 8 cases as to adults with clear cell sarcoma of kidney until December 1995. There was no report about it in the Republic of Korea. We report two adult patients, a young man and a young woman, who had a clear cell sarcoma of kidney.

PURPOSE: To investigate the effects of irradiation on the calcium content and calcific nodule formation in the MC3T3-E1 osteoblastic cell line. MATERIALS AND METHODS: Cells were irradiated with a single dose of 2, 4 and 8 Gy at a dose rate of 5.38 Gy/min using a Cs-137 irradiator. After irradiation, the calcium content and calcific nodule formation were examined on the 1st, 2nd, 3rd and 4th week. RESULTS: A decreasing dose-dependent tendency of the cell proliferation rate was found in all irradiated groups of this experiment when compared with the unirradiated control group. In accordance with the duration of culture, there was no significant difference in the cell proliferation rate after irradiation of 2 Gy when compared with the unirradiated group, however a decreasing tendency was found in 4 Gy- and 8 Gy-irradiated groups. While an increase in total calcium content after irradiation of 2 Gy was found at week 1, week 2, and week 4, there was a decrease in calcium content at week 1 through 4 in the 8 Gy- irradiated group. Calcific nodule formation was increased in irradiated experimental groups when compared with the unirradiated control group in the 2 Gyirradiated group, but decreased in the 4Gy- and 8Gy-irradiated groups at the same stage. CONCLUSION: The results showed a mild increasing tendency of the calcific nodule formation after irradiation of 2 Gy. However, a decreased calcific nodule formation in 4Gy- and 8Gy-irradiated groups was found. Taken together, the irradiation of 2 Gy mildly activated bone formation, however 4 Gy or 8 Gy suppressed bone formation by decreasing cell numbers in the MC3T3-E1 osteoblastic cell line.

Introduction of acrylic cement during total hip replacement has become popular in the las 30 years. Sometimes it precipitates severe hypotension and cardiac arrest, and may be due to toxicity of methylmethacrylae monomer. Fat embolism, air embolism, or neurogenic reflex may be other possible causes of the hypotension. The anesthetist should keep in mind these risk factors, and to prevent these adverse effects, the central venous pressure line, esophageal sterthoscope or Doppler ultrasonic transducer, and adequate fluid volume maintenance are required. We have experienced two cases of complication following bone cement insertion: One case developed severe hypotension and the other case cardiac arrest. The former occured under epidural anesthesia and the latter under general anesthesia after prosthetic implantation in a total hip replacement.
