The relationship between infective endocarditis and mycotic aneurysm formation appers clear : In about two to ten percent of patients with infective endocarditis harbor septic intracranial aneurysms. But the pathogenesis, natural course and management of these lesions remains controversial. Aggressive medical treatment of the underlying infected cardiac valve or surgical replacement therapy have significantly reduced the morbidity and mortality rates associated with infective endocarditis. Clinical predictors of mycotic aneurysm, especially neurologic prodromes prior to rupture have been ill-defined since most series contain few patients or include patients with infective aneurysms who have no infective endoarditis. Similarly there has been no consensus regarding the indications and timing of cerebral angiography in patients with infective endocarditis. We have experienced a case of cerebral mycotic aneurysm complicated with subarachnoid hemorrhage due to infective endocarditis in a 29 year-old female patient, who admitted to our hospital because of the pain and paralysis of sudden onset in right forearm, which was diagnosed by echocardiography, brain computed tomography and 4-vessel cerebral angiography. The patient died of sudden rupture of mycotic aneurysm in the 7th hospital day despite intensive medical treatment. We report one case of cerebral mycotic aneurysm with a brief of literature.

OBJECTIVE: The aim of this study was to identify a transcriptomic signature that could be used to classify subjects with autism spectrum disorder (ASD) compared to controls on the basis of blood gene expression profiles. The gene expression profiles could ultimately be used as diagnostic biomarkers for ASD. METHODS: We used the published microarray data (GSE26415) from the Gene Expression Omnibus database, which included 21 young adults with ASD and 21 age- and sex-matched unaffected controls. Nineteen differentially expressed probes were identified from a training dataset (n=26, 13 ASD cases and 13 controls) using the limma package in R language (adjusted p value <0.05) and were further analyzed in a test dataset (n=16, 8 ASD cases and 8 controls) using machine learning algorithms. RESULTS: Hierarchical cluster analysis showed that subjects with ASD were relatively well-discriminated from controls. Based on the support vector machine and K-nearest neighbors analysis, validation of 19-DE probes with a test dataset resulted in an overall class prediction accuracy of 93.8% as well as a sensitivity and specificity of 100% and 87.5%, respectively. CONCLUSION: The results of our exploratory study suggest that the gene expression profiles identified from the peripheral blood samples of young adults with ASD can be used to identify a biological signature for ASD. Further study using a larger cohort and more homogeneous datasets is required to improve the diagnostic accuracy.

Torsade de pointes (TdP) is a form of polymorphic ventricular tachycardia that is associated with prolongation of the QT interval. Although it occurs in many clinical settings, torsade de pointes is most commonly caused by drugs. The second generation antihistamines, including terfenadine and astemizole, have little sedation or other adverse effects on the CNS. They have been used widely to treat various allergic diseases, but it has been reported that overdoses or combinations with antifungal agents or macrolide antibiotics may lead to TdP. We report a case of TdP that occured during com-bination therapy of terfenadine and ketoconazole.

Takayasu's arteritis(TA) is a nonspecific areritis of unknown etiology affecting segmentally the aorta and its main branches, which result in stenosis, occlusion or aneurysm of involved arteries. The clinical manifestations present with a variety of symptoms such as headache, dyspnea on exertion, pain and weakness of extremities, pulse deficit, and hypertension according to involves arteries. Usually it can be managed by medical or surgical treatment, and recently by percutaneous transluminal balloon angioplasty. The type III classified by Lupi-Herrena and associates is the most frequent variety of TA. However the case of type III involving both subclavin arteries and both renal arteries has rarely been reported. We experienced a case of TA involving both subcalvian arteries, and both renal arteries presented with paroxysmal hypertension and right flank pain, in which the stenosis of both subclavian arteries were managed by percutaneous transluminal balloon angioplasty and the stenosis and occlusion of both renal arteries were successfully managed by aorto-renal bypass surgery with autogenous right iliac artery and synthetic vessel(Gortex). The patient was discharged uneventfully.

Sclerotic fibroma is a rare skin neoplasm that can occur seen sporadically or in association with Cowden's disease. Clinically, it presents as asymptomatic flesh-colored or pinkish slow-growing papules or nodules with a wide anatomical distribution. We report a rare case of pedunculated type of sclerotic fibroma resembling soft fibroma, which has not been reported in Korea.

Pseudo-inflammatory tumors are also known as plasma cell granuloma, inflammatory pseudo-tumor and inflammatory myofibroblastic tumor, and these tumors are a group of highly variable proliferations of myofibroblastic cells that are associated with a prominent inflammatory infiltrate. This tumor is known to most commonly occur in the lungs, bladder and gastrointestinal system with only a few cases having been reported in the skin. A previously healthy 26-year-old man presented with a 6-year history of an intermittently pruritic lesion on his back. On the histologic examination, there were spindle cells in fascicles and a mixed inflammatory cellular infiltrate of plasma cells and lymphocytes. A diagnosis of inflammatory fibroblastic tumor was made and the nodule was surgically removed. We report here on an additional case of this rare cutaneous entity, and it is probably the first such report from Korea.

Vitamin K1 dermatitis is a cutaneous adverse reaction to vitamin K1, and this malady presents as an erythematous eczematoid patch or pseudoscleroderma. At first, liver disease was thought to be related to vitamin K1 dermatitis. However, it is no longer considered as being related to liver disease due to the increasing case reports of patients with vitamin K1 dermatitis and who are without liver disease. Type IV hypersensitivity reaction was suspected to be the cause of this reaction. This disease can be easily ignored because of its low incidence. We hereby report on a case of vitamin K1 dermatitis that was confirmed by a skin test.

Kaposi's sarcoma (KS) is a multifocal proliferative vascular tumor involving cutaneous and extra-cutaneous tissues. KS has been reported in patients treated with immunosuppressive agents for autoimmune diseases. However, KS has rarely been reported in patients with iatrogenic Cushing's syndrome. A 77-year-old woman was evaluated with multiple asymptomatic violaceous nodules and plaques on both lower legs. She had been diagnosed with iatrogenic Cushing's syndrome and had been treated with low-dose corticosteroid replacement therapy for >10 years. A histopathologic study showed extensive vascular proliferation in the dermis with spindle-shaped cells. Immunohistochemical staining for CD31, CD34, human herpesvirus (HHV)-8, and D2-40 was positive. We hereby report a case of KS in a patient with iatrogenic Cushing's syndrome.

BACKGROUND: Exercise-induced coronary spasm is occasionally recognized in patients with variant angina, but the patterns of exercise-induced coronary spasm and its relation to clinical features are still not clear. METHODS: Eight consecutive patients with variant angina without significant stenosis of the coronary artery performed serial treadmill exercise tests during early morning, late morning, and in the afternoon. The subjects repeated the tests after administration of atropine and doxazosin or phentolamine. RESULTS: (Upon drug administration), anginal episodes with ST-segment changes (elevation 5, depression 1) Occurred repeatedly in 6 of the 8 patients during early morning; the episodes occurred in only 2 patients during the afternoon exercise test. Four patients showed exercise-induced angina and ST-segment changes during early morning but not in the afternoon, and 2 of them showed mild episodes of exercise-induced angina and ST-segment changes during late morning. Three of the four patients had the characteristic clinical history of angina in early morning during usual activities but not during daytime activities despite the activities being more strenuous. Another 2 patients showed both exercise-induced ST-segment elevation and angina in early morning and afternoon, and they had the characteristic history of more episodes at night and in early morning but only occasionally in the daytime with or without relation to activity. One of the two patients showed intermittent ST-segment elevation during the exercise test. The other two patients had exercise-induced episodes neither in the early morning nor in the afternoon; they had a characteristic history of episodes only at night during sleep but never in the early morning nor in the daytime. Atropine did not suppress the exercise-induced angina in 4 of 5 patients studied. Doxazosin or phentolamine suppressed the exercise-induced episodes in 3 of 5 patients studied but aggravated spontaneous episodes in 3 patients. CONCLUSION: These data suggest that there's possibility of presence of different patterns of exercise-induced coronary spasm, which may be induced by different mechanisms from those in spontaneous episodes in patients with variant angina.

PURPOSE: Febrile seizure (FS) is the most common type of seizure in children between 6 months to 5 years of age. A family history of febrile seizures can increase the risk a child will have a FS. Yet, prevalence of FS regarding external environment has not been clearly proved. This study attempts to determine the association between prevalence of FS and weather. METHODS: This study included medical records from the Korea National Health Insurance Review and Assessment Service. Data were collected from 29,240 children, born after 2004, diagnosed with FS who were admitted to one of the hospitals in Seoul, Korea, between January 2009 and December 2013. During the corresponding time period, data from the Korea Meteorological Administration on daily monitoring of four meteorological factors (sea-level pressure, amount of precipitation, humidity and temperature) were collected. The relationships of FS prevalence and each meteorological factor will be designed using Poisson generalized additive model (GAM). Also, the contributory effect of viral infections on FS prevalence and weather will be discussed. RESULTS: The amount of precipitation was divided into two groups for comparison: one with less than 5 mm and the other with equal to or more than 5 mm. As a result of Poisson GAM, higher prevalence of FS showed a correlation with smaller amount of precipitation. Smoothing function was used to classify the relationships between three variables (sea-level pressure, humidity, and temperature) and prevalence of FS. FS prevalence was correlated with lower sea-level pressure and lower humidity. FS prevalence was high in two temperature ranges (-7 to -1℃ and 18–21℃). CONCLUSION: Low sea-level pressure, small amount of precipitation, and low relative air humidity may increase FS prevalence risk.
