A 60 year-old right-handed man developed a sudden inability to find his way home from work. Neurologic examina-tions revealed no focal neurological deficit. Neuropsychological tests showed a memory deficit especially in the visu-ospatial domain along with visuospatial and frontal-executive dysfunction. A brain MRI revealed a small but discrete lesion in the right thalamus. The majority of the lesion was confined to the dorsomedial nucleus. These results suggest that a small unilateral thalamic infarction affecting the anterior area may be sufficient to produce "strategic-infarct dementia" without focal neurological deficit.

Primary tracheal tumors, especially lipoma, are very rare. Symptoms of tracheal tumor mimic common upper airway diseases. It is important that they may initially be misdiagnosi4 to bronchial asthma, chronic bronchitis, resulting in a delay in diagnosis. We report a case of tracheal lipoma who was found 6 months after first noticing symptoms including dyspnea, foreign body sensation, successfully removed by bronchoscopic polypectomy.

The provocation test of variant angina are known as ergonovine test, hyperventilation, acetylcholine, exercise and cold pressor test, but beta-blocker provocation test has not been reported as a case. So, this paper reports on the diagnosis of variant angina by beta-blocker provocation test and the case of subendocardial infarcion induced by this test. This study reports with literature and investigation about the following case : A 45-year-old man with a history of recurrent episode of typical angina on the early morning for the past 20 days. He was administrated beta-blocker given by oral route, and on the next morning there was chest pain as same degree as before, Holter EKG displayed ST segment elevation and ventricular tachycardia. It was confirmed focal spasm on coronary angiography, ST segment elevation on EKG, and newly developed hypokinesia on left ventriculogram and followed-up echocardiagraphy. When the chest pain is absent, EGK was normal. And we confirmed that elevation of cardiac enzyme was absent as a result of serial follow up study.

Coronary vasospasm plays an important role in the pathogenesis not only of variant angina, but also of ischemic heart disease in general, including other forms of angina pectoris, acute myocardial infarction, and sudden death. Vasoactive events leading to an acute reduction in regional myocardial flow in the presence of a normal or previously compromised circulation are a common cause of arrhythmias. However, coronary vasospasm-induced electrical and mechanical complications are rarely reported in patients with angiographically normal or near-normal coronary arteries. This paper presents our experience with a patient presenting with coronary vasospasm-associated ventricular fibrillation without findings of significant coronary artery disease.

PURPOSE: The aim of this study is to report on the results and discuss the role of free flap followed by ipsilateral vascularized fibular transposition (IVFT) for reconstruction of large bone and soft tissue defect combined with infection by open tibia fracture. MATERIALS AND METHODS: During the research period, lasting from December 2002 to June 2008 (Kyung Hee University Medical Center), data were collected from three patients who underwent IVFT after free flap. We analyzed the successiveness and persistency of the infection using free flapping, bone union, and hypertrophy between transposed fibula and tibia. RESULTS: Regarding free flap, successive results were observed in all examples. In the final follow-up results, transposed fibulas all survived, having hypertrophy similar to that of adjacent tibia. CONCLUSION: Reconstruction of tibia defect with free flap followed by IVTF is a useful and safe method for avoidance of the potential risk of infection for patients with a large tibial bone defect and soft tissue defect associated with infection.
