T. verrucosum Infection has been reported for the first time in 1986 in Korea and has been increasing progressively. To evaluate the progress of clinical and histopathological change of dermatophytosis caused by T. verrucosum, inoculation study, using T. verrucosum isolated from infected human (human strain) and from infected cattle (cattle strain), was done in 24 male albino Hartley guinea pig. Their clinical and histopathological changes were evaluated. In addition, comparison for the growth rate between human strain and cattle strain on Sabouraud's glucose agar was made. The results were as follows: 1. Growth rate on Sabouraud's glucose agar: Cattle strain showed significantly more rapid growth rate than human strain on Sabouraud's glucose rate at 25℃ and 37℃. And cattle strain showed more rapid growth rate at 37℃ than 25℃. But human strain showed no significant difference of growth rate at both temperature. 2. Clinical findings: Initial erythema, scale and crust were developed about 8th after inoculation. All three findings reached maximum severity about 12th to 16th day and disappeared about 30th to 34th day after inoculation. There was no significant difference in progress of erythema, scale and crust between cattle strain and human strain. 3. Histopathological findings: Although mild acanthosis was noticed on the 3rd day after inoculation, the other findings including parakeratosis, intraepidermal abscess, spongiosis and vascular change, cellular infiltration were found on 9th day after inoculation. They reached maximum severity on the 12th day and lasted to the 25th day after inoculation. After that, all three findings were decreased gradually between 29th day and 33th day. On the PAS staining, hyphae and spores were found on the 6th day and disappeared on the 21th day after inoculation. 4. In trichophyton skin test, all of the 24 guinea pigs became positive within average 9.83±1.17 days These findings suggested that dermatophytosis caused by T.verrucosum induced rapid cell mediated immunity and contributed to rapid resolution of the lesion.

Purpura fulminans (gangrenosa) is a rare clinical syndrome characterized by sudden appearance of rapidly progressive symmetrical subcutaneous ecchymosis durimg the convalescent stage of various infectious disease. A 4 year-old. boy has developed multiple skin defects with necrosis on extrernities and gangrenous changes on the left foot following a meningococcemia. B-K amputation on left leg and. free skin graft for multiple skin defect on extremities were, carried out.

The purpose of this study was to examine the trends of length of hospital stay (LOS), which is most likely to be a major attribute to hospital performance From 1984 to 1994, an average LOS of each hospital was analyzed by factors such as medical departments, bed size, occupancy rate, region and ownership. This study was analyzed changing rate of LOS during 11 years. This rate was calculated by simple regression, which was used only with hospital without missing data during 11 years. This study findings are as follows. 1. The results indicated that the average LOS was steadily increased until 1990 but it was slightly decreased after 1990. 2. This trend could be found in all hospital scale and all group of occupancy rate. Specifically this trends of LOS were found in internal medicine, corporate owned hospitals, and hospitals in major city. But LOS of individual owned hospital was continuously increased until 1994. 3. Means of changing rates of LOS were calculated from 1984 to 1994. If we divided it into two parts, before 1990 and after 1990, most changing rates of LOS before 1990 except individual owned hospital were found positive sign. The changing rates after 1990 were negative sign but small hospital(lesser then 200 bed), individual owned hospital, national & public hospital and hospital in small urban have little change of LOS after 1990. Finally from this results we thought that most hospitals in korea began to be concerned with LOS. Nevertheless LOS of several hospital such as small hospital or individual owned hospital was increased. And this trend may be caused by a few patients, low occupancy rate, or low profit. This trend of LOS is different from that of other countries. Perhaps this phenomenon is resulted from the reimbursement method. Because of fee for service reimbursement system in korea the hospitals didn't need to shorten LOS in order to save the cost and increase the profit. Therefore reform of hospital cost reimbursement method will be reduced to reduce hospital cost in korea. we thought that the korean health authority should consider the reimbursement method by unit of bundle of services, for example DRG and prepayment in the united states. This study presents some limitations such as on insight of severity of disease, case-mix measurement of hospital, and other clinical characteristics that can possibly affect LOS, However, this study reports an important trend in LOS from 1984 to 1994.

Actinomycosis is a chronic suppurative and granulomatous bacterial infection characterized by contiguous spread, abscess formation and sinus tract formation. There are four clinical forms according to the lesional site, as 1) cervicofacial, 2) thoracic, 3) abdominal, and 4) disseminated form. Recently, we experienced a case of 54 year-old patient with left mandibular actinomycosis. The pathognomonic findings of actinomycosis is sulfur granule with multiple filaments in Gram-stain and the treatment of actinomycosis is surgical excision of mass or sinus tract with massive antibiotics (esp. Penicillin) therapy for 6 to 12 months.

Notch stenosis had been thought to be related with anterior cruciate ligament (ACL) injury. The purpose of this study is to evaluate the possible relationship between notch stenosis and ACL injury. We measured the notch seen on the axial section in MRI at popliteal groove. We have retrospectively analyzed 116 cases of knee MRI. All cases were divided into three groups ; Group I were fifty six normal knee. Group II were thirty knee with contact ACL injuries. Group III were thirty knee with non contact ACL injuries. The result were as follows; 1. Statistically significant difference was found in the notch width index (NWI) between group I and group III but no significant differences was found in the NWI between group I and group II. 2. Statistically significant correlation to non-contact ACL injuries was found in the NWI at both anterior and posterior outlet of the notch. 3. An unique shape of the notch was found in the majority of group III.There seemed to be an obvious relationship between notch stenosis and non-contact ACL injuries.

OBJECTIVE: The purposes of this article are to present 5 cases of intracranial meningioma with leptomeningeal dissemination (LD) and investigate the characteristics of this disease. METHODS: We present a retrospective case series of 5 females at our institutions (age ranged 21-72 years, mean 54.6 years) diagnosed with LD of an intracranial meningioma after surgery between 1998 and 2013. A database search revealed 45 cases with LD of meningioma in the English literature. Characteristic features were analyzed and compared. RESULTS: The incidence rate at our institutions of LD of meningioma was 0.9% (5/534). World Health Organization (WHO) grade was distributed as follows: I : 2, II : 2, and III : 1. Time to LD ranged from 2.5 months to 6.9 years; the patient with WHO grade III had the shortest interval to LD. The patient with an intraventricular meningioma (WHO grade II) had the second shortest interval to LD (1.7 years), and simultaneously revealed both LD and extraneuronal metastases. Four of 5 patients showed a disease progression, with the survival ranging from 1 month to 3.8 years after LD. Based on the literature, the initial tumor was an intraventricular meningioma in 9 patients, and their time to LD was shorter on average (mean 1.9 years). Histologically, 26 of 45 (58%) were initially diagnosed with a WHO grade II or III meningioma, and 6 of 19 patients (32%) with WHO grade I revealed malignant transformation. CONCLUSION: This study shows that intraventricular location and histologically aggressive features seem to increase the chance of LD of meningioma.
