Giardiasis is one of the most common causes of infectious diarrhea and it has a worldwide distribution. Although it is a relatively common disorder, histologically confirmed Giardiasis is a rare occurrence and there have been no previous reports in Korea. A 34-year-old man presented with a 2-year history of epigastric discomfort and left flank pain. On stool examination, many cystic forms of Giardia lamblia were noted. In biopsy specimens of the small intestine, there was moderate chronic inflammatory cell infiltration and several trophozoites of Giardia were observed in the intervillous space and luminal surface. The trophozoites were pear shaped symmetrical organisms with two nuclei, and measured 9~10 micrometer in length.

A clinical observation was made on the 236 patients who had undergone transurethral resection of bladder tumor(TUR) between Jan. 1990. and Feb. 1996. in the Department of Urology, Korea Cancer Center focusing on complications. The mean operating time was 59.0 minutes(n=400). The most common immediate complication was bleeding(1.8%), and the remainder was nonurologic fever(0.8%). The delayed complication was urethral stricture(1.0%) requiting visual urethrotomy. The immediate postoperative morbidity was 2.5% and risk factors for immediate morbidity after TUR were operating time longer than 60 minutes and tumor, invading the muscle or more deeply(p<0.05, by Chi-square test). The delayed morbidity was 1. 0% and the only risk factor for delayed morbidity after TUR was the number of ~IJR more than 2(p<0.05, by Chi-square test). Careful attention to surgical details and indications is needed to reduce the amount and significance of the postoperative morbidity.

Pancreatic islet cell adenoma is a benign tumor of pancreatic beta-cell and a rare cause of hyperinsulinemic hypoglycemia in children. The authors experienced a case of pancreatic islet cell adenoma(Insulinoma)in a 11 year and 8 month old male who had frequent loss of consciousness and seizure. Enucleation was done after localization of tumor by selective celiac artery angiography and abdominal computed tomography. Diagnosis was confirmed by histologic findings as pancreatic-adenoma, gyriform growth pattern. A brief review of related literature was made.

Dermatofibroma with granular cells is composed mainly of spindle shaped cells mixed with in-conspicuous foamy cells that contain granular cytoplasm. We present a case of dermatofibroma with granular cells in a 36-year-old male who visited our clinic to evaluate a slow-growing nodule on the medial side of the left lawer leg. He have had the nodule for five years and sometimes felt an itching sensation. Biopsy of the nodule identified a dermal nodular tumor showing cellular spindle cell proliferation admixed with peripheral foamy histiocytes. With the immunohistochemical staining, the granular cell was positive for alpha-1-antitrypsin and CD68, and negative for S-100. A few electron-dense granules were seen in the cytoplasm on the electronmicroscopic study. These results suggested that the granular cells originated from histiocytes.

Prazosin hydrochloride, a new antihypertensive agent with a unique sympatholytic mode of action, was evaluated in 35 cases with essential hypertension. The treatment was started with 3 or 4 mg of prazosin daily divided into 2 or 3 doses, and the dosage was gradually increased weekly up to 20 mg per day depending on the response of the blood pressure. Observations with this drug varied from three to ten weeks, the average being five weeks. In 21 out of 35 cases (60.0%), satisfactory reductions in systolic and diastolic blood pressures with prazosin were noted in both supine and standing positions. These were accompanied by no significant postural hypotension. In 15 out of 21 cases of satisfactory responders, the diastolic blood pressure fell to 90mmHg or less, and in five cases out of 14 poor responders prazosin was given only for three weeks. The average time lapse before effectiveness of the drug in mild, moderate and severe hypertensive cases was 3.3, 3.5 and 6.5weeks, respectively. The average daily effective dosage of prazosin in these groups was 7.1, 9.1 and 12.0mg, respectively. The cardinal unpleasant symptoms appeared in eight out of 35 cases during the medication. These included postural dizziness, weakness, headache, drowsiness and urinary frequency. However, in all cases, except one in which urinary frequency was noted, the symptoms were mild and transient disappearing spontaneously despite continued administration of prazosin. No significant changes were noted in complete blood conuts and routine urinalysis as well as in S-GOT, S-GPT, blood urea nitrogen and serum creatinine levels examined during and after medication.
