A neurilemmoma or schwann cell tumor is a rare and distintive nerve sheath tumor. Neurilemmomas usually are solitary and affect woman more frequently than men withaut particular affinity for any age group. They occur commonly on the cranial nerve, with the most acoustic nerve. When peripheral neurilemmomas are found, they are seen to occur on nerves in the scalp, face, neck, extremities and also visceral organs. Clinically, they are rounded or ovoid with uniform texture and consistency varyingfrom soft to moderately firm in gray, pink or yellowish color and are accompanied with intermittent radiating pain along the course of a peripheral nerve. We present a case report in a 28 year old man who developed two coin size ovoid painful masses on the left extremity for 6 months and describe a brief review associated with the analysis of the statistics of 56 cases of neurilemmoma for the past 9 years' duration in our hospital.

In the real-time two-dimensional Doppler flow mapping(2DD) system, Doppler signals are processed using auto-correlation technique, so that the direction, velocity and turbulence of the intracardiac blood flow are displayed by coloration on the B mode image of the heart in real time. Aortic regurgitant flow is imaged as a mosaic jet spurting out from the aortic valve orifice to cardiac chamber. Dynamic features in the direction and extent of regurgitant flow and the site of regurgitation on the aortic valve orifice are readily obtained. Feasibility of the 2DD system in the assesment of aortic regurgitation was examined in 30 cases documented by angiography. In 30 cases, there were 20 cases with aortic regurgitation(AR) aged 16 to 57 years(mean 34) and 10 cases without AR aged 17 to 39 years(mean 30). The underlying disorders of AR were rheumatic in 15 cases, bicuspid aortic valve in 1, ventricular septal defect in 1, aortitis in 1, Marfan's syndrome in 1 and unknown in 1. The results are as follows : 1) In 19 out of 20 cases with AR the 2DD showed regurgitant jet spurting out from valve orifice(sensitivity=95%). One case missed by the 2DD had 1+AR. None of the 10 cases who had no AR manifested the evidence of AR on the 2DD(specificity=100%). 2) There was an excellent positive correlation between the maximal jet length of regurgitant flow on the 2DD and angiographic severity of regurgitation(r=0.998, p<0.001). The maximal jet length was less than 3cm for cases with 1+, 3-4.9cm for 2+, 5-5.9cm for 3+, and 6cm or more for 4+AR. 3) In 19 out of 20 cases with AR, the 2DD identifed the anatomic valvular site of regurgitation(sensitivity=95%, specificity=100%). 4) The regurgitant aortic valvular area was measured as 0.6cm2 or less in all of 12 cases with 2+ or less AR, while 0.9cm2 or more in 6 out of 7 cases with 3+or more AR. Thus, a less or greater than 0.8cm2 regurgitant aortic valvular area provides to discriminate between mild(< or = 2+) and severe(> or = 3+) AR. 5) In all 8 cases with fluttering of anterior mitral leaflet and 8 out of 9 cases with fluttering of interventricular septum, a regurgitant jet impinged on them. The results of this investigation indicate that the 2DD system is a very useful and unique noninvasive technique in the detection, estimation of severity and spatial orientation of AR.

BACKGROUND: The purpose of this study was to identify predictive factors for preventive behaviors of falls in elderly inpatients. METHODS: Data on 200 elderly inpatients at one university hospital were collected. Descriptive analysis, independent t-test, analysis of variance, and stepwise multiple regression analysis were done to analyze the data. RESULTS: The high risk group, scoring higher than 5.0 in the degree of self-awareness of fall risk, scored low in knowledge about falls while subjects with activity limitations and not using hearing aids scored significantly high in the same area. Subjects with no training regarding falls and the high risk group scored low in fall efficacy while subjects with activity limitations and using hearing aids scored significantly high in the same area. The degree of self-awareness of fall risk, knowledge about falls, and fall efficacy were significant factors affecting fall prevention activities. CONCLUSIONS: These findings suggest that self-awareness of the risk of falls, knowledge about falls, and fall efficacy are significant factors in preventing falls. These factors should be considered when developing nursing assessment tools and intervention programs for elderly inpatients.

On strains of dematophytes isolated from superficial fungal infection patients, susceptibility tests were undertaken to topical antifungal agents (econazole, clotrimazole, siccanin, and tolnaftate). Minimal inhibitory concentration of the drugs was cletermined after 4 days incubation at room temperature on Sabourauds dextroes agar. Diverse susceptibility pattern was observed among different fungal species. Minor variability of susceptibilities was noted within the same species except for Trichophyton rubrum to econazole and tolnaftate in which a marked variation of susceptibilities was noted, Among drug tested, tolnaftate showed the most strong antifungal action, and Trichophyton mentagrophytes was the least sensitive species to all drugs. Minimal inhibitory concentration levels of each drug are as follows; clotrimazole was in the range of 2-8 mcg/ml., econazole was in the range of 0.06-2 mcg/rnl., siccanin was in the range of 05-2 mcg/ml., and tolnaftate was in the range of 0.01-0.25 mcg/ml.

OBJECTIVE: To determine the differences of expression of Transforming Growth Factor (TGF)-beta1 and TGF-beta2 in the human proliferative, secretory, menopausal endometrium, and in hyperplasia and adenocarcinoma of the endometrium. MATERIALS AND METHODS: Fifty patients were divided into 5 groups. Twenty samples were collected from patients with endometrial hyperplasia (n=l0) and adenocarcinoma(n=10) after hysterectomy. Thirty samples were collected from the normal menstrual cycle and the menopausal women as a control group. The histological types of endometrium were proliferative(n=10), secretory(n=10), menopausal(n=10). Immunohistochemical staining was performed through the use of monoclonal antibodies against anti-human TGF-beta1/ beta2 polycolonal IgG rabbit antibody. Expression of TGF-beta1 and TGF-beta2 were judged positive when the staining revealed color development in 5% or more. Specimens were rated absent, trace, weak, moderate and intense. Then, they were scored 4 in case of intense positive for TGF-beta1 and TGF-beta2, and '0' in case of absent for TGF-beta1 and TGF-beta2 . RESULTS: Mean scores of TGF-beta1 in glandular cell were proliferative(1.0), secretory (2.3), menopausal endometrium(1.0), endometrial hyperplasia(0) and adenocarcinoma(0). Expression of TGF-beta2 in glandular cell were proliferative(3.8), secretory(3.3), menopausal endometrium(2.8), endometrial hyperplasia(0.3) and adenocarcinoma(0.3). No specific different expression of TGF-beta1 and TGF-beta2 was found between stromal, vascular and myometrium. However, there was similar expression of TGF-beta1 and TGF-beta2 in endometrial hyperplasia and adenocarcinoma gmup. CONCLUSIONS: TGF-beta1 and TGF-beta2 may have important roles to suppress the development of the precancerous or cancerous lesions in endometrial glandular cells.

BACKGROUND: Carotid atherosclerosis and aortic at herosclerosis are both a predictor of atherosclertic cardiovascular diseases. However, the relationship between carotid and aortic atherosclerosis is not well known. METHODS: We performed B-mode ultrasound examinations of the carotid arteries in 38 consecutive elderly cases(13 men, mean age 69+/-3 years and 25 women, mean age 69+/-5 years) who underwent transesophageal echocardiography, to assess whether atherosclerosis in the carotid artery correlates with thoracic aortic atherosclerosis or may be a marker for it. RESULTS: The incidence of carotid and thoracic aortic atherosclerotic plaques were 44.7% and 50%, respectively. There was a significant relationship between carotid atherosclerosis and thoracic aortic atherosclerosis(r=0.532, p<0.01), and a increase in the extent of aortic atherosclerosis with increasing grades of carotid atherosclerosis. In the entire study cases, the presence of carotid atherosclerosis had a sensitivity 63.2%, specificity 73.7%, positive value 72.6% and negative predictive value 66.7% in detec-ting thoracic aortic atherosclerosis. CONCLUSION: In the Korean elderly, B-mode ultra sound examination of the carotid arteries is a easy and useful technique for the prediction of the presence and severity of thoracic atherosclerosis.
