Polycythemia vera combined with coagulation disorder: A case report.: Jae Hee Ahn, Du Ha Lee, Hyo Jin Chun, Myung Soo Hyun, Hyun Woo Lee, Chung Sook Kim; Yeungnam Univ J Med. 1989;6(2):247-255. Published online December 31, 1989; DOI: https://doi.org/10.12701/yujm.1989.6.2.247

Abstract PDF: We report a case of polycythemia vera combined with coagulation disorder. The patient was 54 years old man who complained of continuous bleeding after incision of skin abscess 20days ago. Laboratory tests were revealed prolonged aPTT and slightly prolonged PT. Coagulation factor, I, VIII, IX, XI and fibrinogen decreased, however FDP did not increased. It appears that patient with polycythemia vera have chronic activation of coagulation system, probably initiated by activation of factor XII. Platelet aggregation test to ADP, collagen, epinephrine was also revealed poor response.

One Case of Insulinoma.: Jae Hee Ahn, Hye Sang Seo, Sung Chul Yoon, Kyung Woo Yoon, Soo Bong Choi, Hyun Woo Lee; Yeungnam Univ J Med. 1988;5(2):205-211. Published online December 31, 1988; DOI: https://doi.org/10.12701/yujm.1988.5.2.205

Abstract PDF: Insulinoma is a rare tumor, occurring more often in women and in the older age range. Eighty percent of patients have a single benign tumor, usually 2 cm in diameter, located with about equal frequency in body, head or tail of pancreas and amenable to surgical cure. About 10% have multiple tumors. The remaining 10% of patients have metastatic malignant insulinoma. The symptom of insulinoma is characterized by the periodic attack of hypoglycemia of blood sugar level below 50mg%, by fasting or exertion, and rapid relief of symptom by oral or intravenous administration of glucose. Symptom often lead to misdiagnosis as a neurologic or psychiatric disorder. A case described by authors was 44-year old female with the chief complaints of the loss of consciousness, epileptic seizure although she has been treated by anticonvulsants. Serum blood sugar and insulin level during fasting suggested insulinoma but abdominal computed tomography shows no definitive mass in pancreas. Celiac angiography revealed insulinoma. She transferred to the department of General Surgery and was performed enucleation. Microscopic findings shows the islet cell tumor of pancreas. A brief review of the literature was made.

The Bronchodilatory Effect of Ipratropium Bromide on Bronchial Asthma.: Jae Hee Ahn, Tae Nyeon Kim, Young Hyeun Lee, Jae Chun Chung, Hyun Woo Lee; Yeungnam Univ J Med. 1988;5(2):95-100. Published online December 31, 1988; DOI: https://doi.org/10.12701/yujm.1988.5.2.95

Abstract PDF: Ipratropium bromide (IP) is a new anticholinergic bronchodilator. To evaluate its effect on bronchial asthma which is still unknown in Korea, a double blind and randomized study was done on all patients of bronchial asthma who visit out-patients clinic of out department from June to September 197 and showed 75 to 100% of FEV1/FVC ratio on prebronchodilator spirometry (pre BD). The selected patients were given 2 puffs of Fenoterol (FE) or Ipratropium inhalator blindly and Spirometry. The repeated results are: 1. In both FE and IP groups, there was a significant bronchodilatory effect on 5 and 60 minutes after administration. 2. One 5 minutes, effect of FE was significantly greater than IP (FVC p<0.05, FEV1 p<0.01). 3. One 60 minutes, effect of IP was slightly less than FE but statistically non-significant. On the basis of above results, we concluded that onset of effect of IP is slower than FE, but its effect is significant and nearly comparable to FE.
