Any type of urticaria may affect as many as 20% person during their lifetimes, yet the causes of this disorder is established in no more than 20% of cases. So, 308 patients with urticaria(acute ; 73, factitial; 120, chronic;115) were evaluated for results of historical and laboratory tests. The results were summerized as follows,' 1. The disesse primarily affected 2nd % 3rd decade(46.2%) with predominance of woman than man (M: F=1: 1.4). 2. Ninety-seven(31.5%) had at least one abnormal finding in the laboratory tests but, may be twenty-three(7.5%) would have causal relationship. 3. We sought serologic markers of Hepatitis B virus infection in serum from 8(14%) of 57 patients with urticaria. Of these, 4 were found to have abnormal liver function. 4. Sixty-five had taken at least one sort of drug previously or just before urticaria developed, but, may be forty-six(14.9%) would have a causal relationship and the predisposing drugs were analgesics, antibiotics, common cold medication & vitamin etc. 5. The predisposing conditions were as follows ; pulmory tuberculosis, viral hepatitis, hyperthyroidism, tonsillitis & ascariasis, etc. Of these, eleven(3.6%) of this patients were newly found to have underlying diseases. 6. This study showed inciting factors of urticaria in 27.2%(84/308).

OBJECTIVE: Internal carotid artery (ICA) trunk aneurysms are rare constituting about 0.9 to 6.5% of all ICA aneurysms. They may arise from medial, lateral, ventral (posterior) or dorsal (anterior) walls of ICA. The most frequent site of origin is dorsomedial, followed by dorsal, dorsolateral and ventromedial wall. ICA dorsal wall aneurysms can be divided into the saccular type and blister type, which have different shapes, wall histological features and surgical tactics. The authors report an analysis of 27 cases of ICA trunk aneurysms treated with surgical clipping or GDC embolization. METHODS: Of 145 cases of ICA aneurysms from May 1998 to December 2005, we found 27 cases (17.5%) of such unusual aneurysms located at nonbranching sites of the intradural ICA. Features of neuroimagings and medical records were analyzed. RESULTS: Out of 27 aneurysms, 10 were located at ICA dorsal wall, 8 aneurysms were developed at ICA medialwall. Seven aneurysms originated from ICA ventral wall. Seven cases presented with subarachnoid hemorrhage and 20 cases were found unruptured. Two patients had blister-like aneurysm, and the others had saccular aneurysms. All patients were treated successfully with microsurgical clippings or GDC embolization. Microsurgical clipping were performed in 14 cases and among them, removal of anterior clinoid process was done in 12 cases. Eleven aneurysms were occluded with detachabel coil. Two patients underwent balloon occlusion of ICA. Blister aneurysm was clipped including a portion of the normal ICA wall. Good outcomes were obtained in 25 patients, and two patients were dead. CONCLUSION: ICA trunk aneurysms are developed at any site of ICA circumference. Therefore we consider a variety of treatment strategies. On clipping of aneurysms at proximal ICA trunk, removal of anterior clinoid process is important. Endovascular treatment may be good an alternative. However, surgical treatment is essential for blister like aneurysms.
