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.

To ease the convinience of indentification of common dermatophytes in Korea and to check the possibility of diseovering new species not yet reported in Korea, several species of dermatophytes were cultured on potato dextrose agar(PDA) at the room temperature. They were 46 strains isolated from Korea and 6 domestic strains from a foreign country. Gross and microscopic findings of their colonies were examined. The colonial morphology and microscopic appearance were compared with those of the same strains on Sabouraud dextrose agar(SDA) and corn meal agar(CMA). The results were as follows Typical T. rubrum and its varisnts showed characteristic wine red pigmentation which was rapid, diffuse and uniform, typically arrsnged microconidia were better on PDA. T. mentagrophytes showed yellow-brown pigmentation which were more rapid and darker in the center with gradual fading to the periphery. The mscroconidia, grape-like clusters of microconidia and spiral hyphae were seen better on SDA. T. tonsurans showed characteristic mahogsny colored pigmentation, ballooned microconidia and macroconidia which were seen better on PDA, but diffusible pigmentation of agar were present on SDA only. The gross morphology of T. verracosum were similar on PDA and SDA, but macroconidia were seen better on PDA and CMA, and tortuous hyphae with antler-like branching were seen better on SDA. T. rnegninii showed green-brown pigmentation which appeared rapidty and prominently on PDA. T. rubrum-like microconidia were seen better on PDA and CMA, but in SDA only hyphae were seen. The gross morpholgy of M. canis was similar on PDA and SDA, but spindle shaped macroconidia were seen more typically on PDA. The gross morphology and microscopic appearance of M. gypseum were very similar in all three media. M. ferruginenm showed characteristic rust colored pigmentation and bamboo hyphae which were seen more typically on PDA. The gross morphalogy of E floceosum were similar on PDA and SDA, but cluster formation of club shaped macroconidia were seen more prominently on PDA and CMA. These findings suggest that PDA is a mare convincing media t6Cifferentiate among dermatophytes belonging to genus Trichopkyton.

Osteoblastoma is a benign lesion somewhat similar to ostoid osteoma histologically but different from it clinically, roentgenologically and grossly. The autors have experienced a case of benign osteoblastoma of the neural arch of the Iumbar spine, and treated the case by total laminectomy and conflrmed with biopsy.

We present a case of multiple cutaneous leiomyoma in a 45 year old woman. About 20 years ago, multiple skin colored papules developed on right cheek and man4ibular area. About 10 years after the onset of the disease a uterine myoma developed which wae tree,ted by total hysterectomy. The skin lesions were gradually increasing in number and size, Some larger nodular lesions changed to brown in color and became painful after cold exposure. The histopathologic finding showed typical leiomyoma arieing from arrector pilorum muscle.

To evaluate the progress of clinical and histopathological changes of dermat ophytosis caused by M. gypseum, its inoculation study was done in 16 male New Zealand white rabbits(control: 4, innoculation : l2). The results were as follows . Clinically Initial erythema, scales, and crusts developed in 1 week after inoculation. They reached maximum severity on the 14th to 18th day and disappeared on the 25th to 44th day after inoculation. I-Iist,opathologically : The earliest findings were mild focal acanthosis and for al vascular ilatations and cellular infiltrations of the papillary dermis on the 4th day after inoculation. Their severity increased to the moderate degree until the. 8th day when mild hyperkeratosis was notec1, and lasted to the 13th day, Maximum degree of the findings including parakiratosis, intraepidermal microabscesses and middermal changes was seen on the 16th to 22nd day, and disapveared gradually between the 25th day and the 46th day. Hyphae and spores were founil on the PAS stainings until the 22nd clay. M. gypseum was not cultured from the lesions after the 25th day. seven of 10 rabbits injected intradermally with trichophytons became positive in 2 to 4 weeks after inoculation. All these findings suggest that the maximum inflammatory response is the result of immunologic reaction and the increased epidermal turnover rate may play a. major role in the shedding of remained fungi of the horny layer.

In January 1988, district medical insurance plan was executed on a national scale in Korea. We conducted an evaluation of the impact of execution of district medical insurance plan on number of hospital patients: number of outpatients; and occupancy rate. This study was carried out by Box-Jenkins time series analysis. We tested the statistical significance with intervention component added to ARIMA model. Results of our time series analysis showed that district medical insurance plan had a significant effect on the number of outpatients and occupancy rate. Due to this plan the number of outpatients had increased by 925 patients every month which is equivalent to 8.3 percents of average monthly insurance outpatients in 1987, and occupancy rate had also increased by 0.12 which is equivalent to 16 percents of that in 1987.
