BACKGROUND: Vibrio vulnificus(V. vulnificus) is a pathogenic, marine, halophilic, Gram negative bacillus which causes fulminant infection in humans through skin wounds. or the ingestion of raw seafoods or Most cases are reported sporadically in summer in the south-western coastal area of Korea. OBJECTIVE: We studied the distribution of V. vulnificus in sea water, fishes, shellfish and sea mud from May to October in 1996 and the relationship between regional distribution and environmental factors. METHODS: We collected the sea water, sea mud, fishes and seafoods from May to October in Kunsan, Daechun, Moochangpo, Puan, Youngkwang and cultured it in Thiosulfate-Citrate-Bile salt-Sucrose(TCBS) agar, Cellobiose-Polymyxin B-Colistin(CPC) agar, and Sodium dodecyl sulfate- Polymyxin B-Sucrose(SPS) agar. At the same time we investigated environmental factors such as temperature, pH, salinity, turbidity, dissolved oxygen(DO), NO3 of sea water. RESULTS: Twelve strains(2.17%) of V. vulnificus were isolated from a total of 552 specimens. The V. vulnificas isolation rate from sea mud was higher than in sea water and shellfish. Areas where V. vulnipcus was isolated were Kunsan and Daechun. It was isolated during June, July and August. The Isolation rate was higher with CPC agar than TCBS, SPS agar. When V.vulnificus was isolated at Kunsan, the environmental factors of sea water noted were as follows: temperature, 25.3C; turbidity, 121Formazine turbidity units; salinity, 12.2%; DO, 7.3mg/L; pH, 7.37 and NO3, 1.18mg/L. CONCLUSION: CPC agar is the best medium of the three above used for the isolation of V. vulnificus from environmental samples. V. vulnificus was highly isolated in the Kunsan area because of the high water temperature and turbidity, low salinity and weak alkali state of the sea water in comparision with other areas. We suggest that high temperature and turbidity, low salinity and weak alkalinity of sea water are very important environmental factors for the growth of V. vulnificus.

3.Spontaneous Resolution of Dissecting Aneurysm Arising from the Posterior Cerebral Artery.
Journal of Korean Neurosurgical Society 2002;31(5):488-490
A case of isolated dissecting aneurysm of the posterior cerebral artery responsible for ischemic episode and subarachnoid hemorrhage is reported. Angiogram showed a fusiform dilatation of the P1-P2 segment of the right posterior cerebral artery. The dissecting aneurysm was disappeared spontaneously on follow-up angiogram. It is recommended that, in a subset of neurologically stable patient who represents fusiform dilatation angiographically, angiographic monitoring should be undertaken to assess the tendency for spontaneous resolution before planning of surgical intervention.

Fenestrations of anterior cerebral arteries are rare anomalies, which may be associated with saccular aneurysms at the fenestration itself or other intracranial vessels. This association is not infrequently the cause of angiographic diagnostic problem, as well as surgical difficulties. We report a case of aneurysm arising from a fenestrated proximal anterior cerebral artery that was confirmed at surgery and discuss together with a review of the literature.

Normal C3WHeN strain mice exposed to topical 8inethoxypsomlen plus long wave ultraviolet (PUVA) showed a reduction in contact hypersensitivity, (CH) which was localized to the skin in the area of PUVA treatment (local suppression), whereas systemic PUVA treatment caused diffuse suppression of CH reaction, regardless of the application site of 2,4-dinitro-1-fluorobenzene (DNFB). There seem to be two different mechanisms responsible for CH reduction by PUVA. Local suppression by topical PUVA treatment was thought to be a result of blocking the afferent phase of immune response, it was associated with a lack of CH effector cells in the peripheral lymph nodes and could not be reversed by indomethacin treatment. Diffuse suppression induced by systemic PUVA treatment seemed to be associated with blocking of egress of effector cells from the regional lymph nodes, this depressed CH response was prevented when indomethacin was administered before PUVA treatment.

6.A Ruptured Aneurysm in a Patient with Systemic Lupus Erythematosus: Case Report.
Journal of Korean Neurosurgical Society 2002;32(1):77-80
A case of ruptured aneurysm in the cerebral artery in a patient with established systemic lupus erythematosus is presented. A 28-year-old woman with a 1-year history of systemic lupus erythematosus was found to have a ruptured saccular cerebral aneurysm at the bifurcation of the left MCA with a fusiform dilatation at the top of the basilar artery. The ruptured aneurysm was treated surgically. Cerebral aneurysms associated with systemic lupus erythematosus are reviewed in the literature and the pathogenesis of these aneurysms is discussed.

PURPOSE: It has been known that there are several areas of T2 hyperintensities in normal white matter of brain, such as terminal zones of myelination, ependymitis granularis, ones of posterior internal capsule, and perivascular space. The aim of our study is to demonstrate another region of T2 hyperintensities in normal pediatric age group. MATERIALS AND METHODS: We have studied brain MR for 10 normal volunteers and 35 patients without having intracranial lesions in pediatric age group(3-19 years). RESULTS: In 5 among 45 cases, focal T2 hyperintensities were seen in the parietal periventricular white matter beneath the postcentral gyri. They were noted as poorly defined, 5--10mm sized areas of increased signal intensities on T2 weighted axial images. They were also characterized by bilateral, posteromedially oriented, short band-like or oval areas. Interestingly, they were directly continuous with the T2 hyperintensity of posterior internal capsule. In spite of the relatively high frequency in the pediatric population as in our study, this finding has not been reported in the asymptomatic adults. CONCLUSION: The results show that the bilateral anterior parietal hyperintense areas may be another terminal zones of delayed myelination affecting the parietopontine tract. They should be differentiated from pathologic T2 hyperintensities by their characteristic findings.

Congenital hypohidrotic ectodermal dysplasia is a rare genodermatosis. It is characterized by hypohidrosis hypotrichosis, dental hypoplasia and characterstic facial features, which reflect a wide constellation of developmental defec of tissue from the ectoderm. We have encountered three cases of congenital hypohidrotic ectodermal dysplasia in a 28-year-old female, her new-born baby, and a 10-month-old boy with a family history. All of the three patients had hypohidrosis, hypotrichosis, defective dentition, and characterstic facial features, which were characterstic features of this disorder. In addition, they showed dry skin, sparse and thin hairs. Histopathologic findings of previous cases revealed no eccrine gland structure in the dermis with routine and immunohistochemical stainning such cytokeratin and filaggrin. We report three typical cases of hypohidrotic ectodermal dysplasia with the review of literature.

BACKGROUND: Confluent and reticulate papillomatosis(CRP) of Gougerot and Carteaud is an uncommon disorder of unknown cause for which a variety of treatments have been proposed. OBJECTIVE: We attempted to evaluate the therapeutic effect of oral minocycline for CRP. METHOD: Nine patients(age range, 14 to 38; mean age, 21years) with CRP were included in this study. They took minocycline 100mg daily. The therapeutic effect was evaluated weekly by 5 scoring systems according to the percentage clearing of the skin lesion: poor (score 1), <25% clearing; fair (score 2), 26-50%; good (score 3), 51-75%; excellent (score 4), 76-95%, clear(score 5), >95%. RESULTS: Two out of 9 patients showed complete clearing(score 5) of the skin lesions within 2 weeks. Seven patients revealed incomplete clearing(score 4) within 3 to 8 weeks. The mean scoring for 9 CRP patients was 4.2. Recurrences were noted in two patients at 24 and 26 months, respectively, but they responded to re-treatment with minocycline. The patients did not show any adverse reactions apart from two patients who developed mild pruritus. CONCLUSION: We recommend minocycline as the first choice of treatment for CRP because minocycline is safe, economic and effective.

We report a 72-year-old female patient with spontaneous rupture of the left external iliac vein. She visited our hospital for abdominal and back pain. She had the abnormal finding of hemoperitoneum. We performed an emergency operation with diagnosis of left ovarian cyst rupture though she suffered from spontaneous rupture of the left external iliac vein. This case provides insight to the experience of spontaneous rupture of the left external iliac vein.
