BACKGROUND: To compare the diagnostic usefulness of dobutamine stress echocardiography(DSE) and 99mTc-methoxyisobutyl isonitrile SPECT (MIBI SPECT), two studies were performed simultaneously. METHOD: Fifty-six consecutive patients undergoing coronary angiogram and MIBI SPECT for clinical indications without clincal evidence of myocardial infarction were studied prospectively. During the DSE, MIBI was injected at peak stress, and post-stress images of MIBI SPECT were required on hour later. Both echocardiographic and MIBI SPECT images were visually analysed in a blind fashion. RESULTS: On the basis of coronary angiographic findings, the sensitivites of the DSE and MIBI SPECT (n=36) were 89% and 86%, respectively. The specificities of those (n=20) were 90% and 85%, respectively. Among 33 patients without resting perfusion defect on MIBI SPECT, resting regional wall motion abnormalities on DSE were found in only one patient, whereas, resting perfusion defect on MIBI SPECT were found in 9 patients among 41 patients without resting regional wall motion abnormalities on DSE. Among 17 patients who had resting perfusion defects with partial reversibility on MIBI SPECT, resting wall motion abnormalities were present in 11 patients and five of them showed improvement in the regional wall motion during low dose dobutamine infusion. CONCLUSION: Both dobutamine stress echocardiography and MIBI SPECT are useful methods in the detection of the coronary artery disease, however, MIBI SPECT seems to overestimate the regional ischemic myocardium with contractile reserve that can hardly be evaluated with MIBI SPECT.

BACKGROUND: Pustular eruptions due to drugs are uncommonly reported. We studied the characteristics of clinical and histopathologic findings of pustular drug eruption. OBJECTIVE: We observed th.e causative agents, clinical featurs and histopathologic findings of pustular drug eruption and identified differential points of generlized pustular eruption. METHODS: We evaluated t,he clinical and histopathologic findings of 8 patients with pustular drug eruption and reviewed the literatures reported cases of pustular drug eruption. RESULTS: All patients diagnosed pustular drug eruption suffered from generalized pustular eruption associated with systemic symptoms such as fever, headachened myagia one to three days after treatment with causative agents. The causative agents of putular drug eruption are antibiotics such as ceftriaxone, analgesics and antipyretics. The pustule resolved after a few days of treatment with systemic corticosteroids and antihistamines. Laboratory findings revealed leukocytosis, neutrophilia, and analevated erythrocyte sedimentation rate, On histopatologic findings, we observed subcorneal pustuls containing neutrophils, eosinophils and some lymphocytes and spongiosis, exocytosis of acute iiflammatory cells. Perivascular infiltration of lymphocyte ancl edema of papillary dermis was also bserved in the dermis. CONCLUSION: Pustular drug eruption is characterized by generalized pustular eruption associated with systemic symptoms and histopathologic findings of that are sterile subcorneal pustules. Therefore differential diagnosis of other generalized pustular erupticns are relatively easy by careful history of medication, clinical and histopathologic findings.

BACKGROUND: Genus of Aspergilli are ubiquitous saprophytic molds in nature, but its change from a saprophytic fungus to a pathogenic organism has occurred since the use of various antibiotics. The fungus affects the chronically ill and debilitated population. Recently frequency of the fungal infection is increasing in Korea with abuse of antibiotics and glucocorticoids. METHOD: We analyzed medical records of 52 patients with pulmonary aspergillosis seen at Hanyang University Hospital from 1980 to 1994. The results were as follows; RESULTS: 1) Ages ranged between second to eighth decades with majority(50%) in the fourth to fifth decades. The male to female ratio was 1.1:1. 2) Hemoptysis and productive cough, the leading symptoms, occurred in 42.3% and 25% respectively. 3) On chest X-ray fingings, the characteristic 'fungus ball' pattern were observed in 53.8% of the 52 cases. 4) Sputum culture for aspergilli were positive in 21.6% of the cases. We performed foe needle aspiration in 22 patients and the diagnostic yield was 100%. 5) Thirty-six patients had history of treatment with antituberculous drugs under diagnosis of pulmonary tuberculosis for an average of 27.3 months. But sputum analysis for acid-fast bacilli were positive in 5.6%(2cases of 36cases), and postoperative pathologic findings showed that 38.9% (12 cases of 28cases) were combined with tuberculosis. 6) Right upper and left upper lobes were predominantly involved(34.6% and 19.2% respectively) and lobectomies were performed in 21 cases. 7) Underlying diseases were present in 47 cases and 48.9% of them were pulmonary tuberculosis. CONCLUSION: These results showed that pulmonary aspergillosis usually develops in patients with open cavitary pulmonary tuberculosis. And we must consider the possibility of pulmonary aspergillosis in a patient with hemoptysis and cavitary lung lesion.
