Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.

Headache associated with moyamoya disease (HAMD) has been reported in about 20-30% of pediatric cases with moyamoya disease. However, the characteristic patterns of HAMD during disease progression are not completely known, although much is known on the incidence of HAMD and on the treatment effects of bypass surgery. In a child who presented with HAMD and had no infarction or hemorrhage till bypass surgery, we described the characteristic patterns of headache progression. At first presentation, the patient complained of severe bilateral headache despite mild stenosis only in the left internal carotid artery on brain magnetic resonance angiography. During all stages of progression, headache was severe and pressing in nature rather than throbbing. Nausea and vomiting were present even in the early stage, but photophobia, phonophobia and neck stiffness developed in the late stage. Headache was aggravated by menstruation and was relieved by analgesics and topiramate in the early stage, although the medication failed to provide relief when the headache increased in frequency and duration.

BACKGROUND: Vitiligo is an acquired depigmentary disorder characterized by loss of melanocytes from the epidermis. Autografting using the suction blistered epidermis technique is one of the surgical modalities of vitiligo treatment, and has been successfully used by several authots. OBJECTIVE: The purpose of this study was to evaluate the effect of the autografting using the suction blistered epidermis technique for the treatment of vitiligo. METHODS: 142 sites from 39 patients with vitiligo were treated with autografting using the suction blistered epidermis technique. The recipient sites were prepared by freezing with liquid nitrogen of the sites 48 hours prior to grafting. RESULTS: Better results were seen in cases with the following Factors: a) cases where the disease had been present for more than 3 years b) the post-operative period had been Longer than a year c) the Lesional sites of the vitiligo were on the trunk and neck rather than the neck and extremities d) the vitiligo had affected the grabous rather than the hairy areas on the face. However, there were no differences between the clinical types(such as generalized, localized, and segmental) in the success rate of treatment. Preopera'tive PUVA or post operative PUVA also did not affect the statistical results. CONCLUSION: On autografting using the suction blistered epidermis, it is better to select the patients who have had the disease for more than 3 years, and graft the epidermis which has increased melanocytes by preoperative PUVA for good treatment results and even pigmentation.

BACKGROUND: It has been recognized for many years that myocardial infarction is almost invariably associated with significant narrowing of one or more coronary arteries. However, the widespread use of selective coronary angiography has resulted in an increasing number of reports of patients with proved infarction and patent coronary arteries. The purpose of this study was to analyze whether any clinical features distinguishes patients with these findings from those having coronary arterial lesions. METHODS: The clinical association of myocardial infarction with no significant stenosis of major coronary artery on cineangiogram was analysed retrospectively. The findings on the 13 patients in this group was compared with those of myocardial infartion with significant coronary artery stenosis. RESULTS: There were no significant differences in risk factors, hemodynamic findings of cardiac catheterization and the site of infarction between both groups. However, the patients with no significant stenosis of coronary artery had fewer complications during hospitalization and lesser ST segment change during exercise test before discharge. CONCLUSION: It could be concluded that the acute myocardial infarction with no significant stenosis of coronary arteries would have the better prognosis. The mechanism of the acute myocardial infarction with no significant stenosis of coronary arteries might be studied in the aspect of the coronary artery spasm and the alternation of function of endothelial cell.

The free flaps have been used for reconstruction of the head and neck because of their superior results comparing with other types of flaps. Among them, radial forearm free flap has many advantages, its thinness, pliablilty, long vascular pedicle, large sensory flap, and compound flap including tendons and bone. We report 28 cases of head and neck reconstruction with radial forearm free flap between March 1991 and March 1997. Patient's age ranged from 21 to 76 years(mean 50.5 years). There were 23 men and 5 women. Mean follow-up period was 14 months. The most common cause was malignant tumor of the head and neck, especially squamous cell carcinomas(18 cases). We used this flap to reconstruct the oral cavity in 13 cases, the hypopharyngoesophagus in 6 cases, external surface of the head and neck in 7 cases, and the orbit in 2 cases. All of these flaps survived without complication. Two cases of fistula developed, in which forearm flaps were used for tongue and hypopharyngoesophageal reconstruction, and they were treated with conservative manners. Partial losses of skin graft at donor site of the forearm developed in 3 cases. They healed with split-thickness skin graft or local flap. The function of reconstructed upper aerodigestive tract and eye socket was good. The cosmetic result was not good in cases of reconstruction for external surface of the face with this flap, but it was better than other free flaps. So, we concluded the radial forearm free flap is available for reconstruction of the head and neck.

A Clinical observation was made on five patients with ruptured right aortic sinus of valsalva who admitted Soonchunhyang College Hospital during the period of may, 1983-Jan., 1985. 1) Age distribution was from 18 to 46 years and four patients were male and the rest one was female. 2) Chief complaints were dyspnea, chest pain and palpitation. Continuous murmur was heard at third and fourth intercostal space along left sternal border with palpable thrill in all cases. 3) The ECG showed left ventricular hypertrophy in 4 cases and the M mode echocardiogram revealed the increased internal dimesion and the augmented motion of the left ventricle in all cases. The 2 dimensional echocardiogram revealed the aneurysmal sac in the right ventricle in 4 cases. 4) The aortogram by DSA method showed regurgitant flow from aorta to right ventricle in 4 cases. The cardiac catheterization showed a significant oxygen step up in the right ventricle in all cases. 5) Operation was done successfully in all cases, of which ventricular septal defect were in 3 cases and aortic regurgitation was in one case.
