Plexiform schwannoma is a rare variant of shwannoma, originating from the nerve sheath. It is very impoirtant to differentiate plexiform schwannoma from plexiform neurofibroma, which is pathognomonic of von Reckilnghausen's disease and carries a significant risk of malignant transformation. Plexiform schwannoma is not necessarily associated with von Reckilnghausen's disease and malignant transformation has never been observed. We present a 11-year-old boy who had a nodole on right forearm with tenderness and a tingling sensation. On the histopathological and immunohistochemical examinations, the lesion showed typical features of plexiform schwannoma, The nodule was totally excised under local anesthcsia. Recurrence has not been observed in the six months follow-up period.

The present study examined cortical cerebral microinfarcts (CMIs) on a 3T magnetic resonance imaging and investigated the impact of CMIs on the comprehensive functional outcomes during the post-stroke rehabilitation period. Patients with acute phase of firstever ischemic stroke were retrospectively recruited (n = 62) and divided into 2 groups with and without CMIs. Clinical parameters including age, sex, stroke lesion laterality, location, the National Institutes of Health Stroke Scale score, as well as history of hypertension, dyslipidemia, diabetes mellitus, and smoking were obtained. Functional outcomes were assessed twice at baseline and one month later with the Korean version of the MiniMental State Examination, the Berg balance scale (BBS), and the functional independence measure. Partial correlation and multiple linear regression analyses were used to examine the relationship between the presence of CMIs and the change in functional outcomes. At least one CMI was reported in 27 patients, who were older (p = 0.043). The presence of CMIs was significantly associated with functional impairment in all 3 functional outcomes, after controlling for confounding factors (p < 0.05). CMIs might contribute to poor functional outcomes during the post-stroke rehabilitation period. These results suggest that CMIs should be considered when establishing rehabilitation treatment strategies or making a prognosis.

PURPOSE: This cross-sectional study was designed to identify anger-expression typesof adolescent women and investigate the relation between the identified anger-expression types and their problem behaviors and health status. METHOD: One hundred ninety nine high school freshmen were recruited from September to November, 2003. Data wasanalyzed using descriptive statistics, cluster analysis, chi-square-test, ANOVA, and Duncan's multiple comparison test. RESULT: Three anger-expression types in adolescent women were found; Anger-out/in, Anger-control/in, and Anger- control type. Adolescent women with frequently using the anger-out/in type and with higher state anger reported more delinquent behaviors, more health risk behaviors, and higher psychosomatic symptoms. However, adolescent women with lower state anger and frequently using the anger-control type reported more depression scores. CONCLUSION: There is a need to further clarify the relationship between anger-expression typesand depression in adolescent women. The findings suggest the necessity of a development of the program for lowering the anger level and controlling the unfavorable anger expression types such as the anger-out in.

OBJECTIVE: To evaluate the viability and the characteristics of shed endometrial tissues obtained from menstrual fluid during in-vitro culture. METHODS: The menstrual fluids were collected using Wallace catheter from uterine cavity in 10 women with regular menstruation. The menstrual fluids were washed twice, and the pellets, containing blood cells and shed endometrium, were collected and diluted fivefold with Ham's F-10 medium containing 10% fetal bovine serum. The cell suspension was placed on culture dishes, and cultured for 7 days in an incubator. To evaluate the characteristics of the cultured endometrial cells, immunohistochemical (IHC) staining was performed using anti-cytokeratin and anti-vimentin antibody. RESULTS: The mean volume of menstrual fluids and pellets were 0.7ml and 0.3ml, respectively. Only 15% of the shed endometrial tissues were attached and proliferated in culture dishes, which was considered to have viability. Initially, endometrial epithelial cells and fibroblasts were attached and proliferated, and the area of these cells was increased according to prolong the culture time. Stromal cell colonys were located and proliferated on the epithelial cells. IHC staining showed strongly positive for cytokeratin in epithelial cells and for vimentin in stromal cells. In the confocal microscopic observation of 3-dimensional structure of cultured endometrium, cytokeratin-positive cells (epithelial cells) were located in the pheriphery and cytokeratin-negative cells (stromal cells) inside of the structure. CONCLUSION: From our study, shed endometrial tissues in menstrual fluid showed meaningful viability and closed relationship between epithelial cells and stromal cells during in-vitro culture. Thus, we suggest that the in-vitro culture system of shed endometrium is a suitable model for researches of endometriosis.

Hemangiopericytoma is a rare vascular tumor arising from pericytes. The tumor usually develops in the skin or subcutaneous tissue, particularly in the extremities.4 pulmonary origin of hemangiopericytoma is known to be quite rare. It has the potential to become a highly malignant lesion, so wide excision is the treatment of choice. We present a case of primary malignant hemangiopericytoma of the lung and discuss the clinical symptoms, diagnosis, therapy and prognosis within the context of a brief review.

OBJECTIVES: Hemodynamic measurements of chronic portal hypertension were done to study the mechanisms that maintain high portal pressure despite well developed collateral circulations. METHODS: A prehepatic portal hypertensive rat model was produced by partial portal vein ligation. Cardiac output, organ blood flow and porto-systemic shunt were measured by radioisotope labeled microsphere methods, and vascular resistance was calculated by standard equation. RESULTS: There was a significant reduction in the weight of the liver and increase in the weight of the spleen in the portal stenotic rats. Porto-systemic shunting, representing development of the collateral circulations, was 96.7+/-0.6% in the portal stenosis group compared with 0.9+/-0.2% in the control group (p<0.01). Portal pressure was significantly increased in the portal stenosis group compared with the control group(12.8+/-1.4 vs. 6.5+/-0.6mmHg; p<0.01). Mean arterial pressure was significantly decreased in portal stenosis group compared with control group(101.4+/-2.5 vs, 129.9+/-3.9mmHg; p<0.01). In the portal stenosis group, cardiac output(135.7+/-8.0 vs. 111.0+/-4.2ml/min; p<0.01) and splanchnic organ blood flow (28.97+/-2.03 vs. 17.90+/-1.27ml/min, p<0.01) were significantly increased, with concomitant decrease in total peripheral vascular resistance(58.0+/-3.3 vs. 88.2+/-4.8 dyne sec/cm5 X 105; p<0.01) and splanchnic vascular resistance(2.54+/-0.20 vs. 5.47+/-0.33 dyne sec/cm5 X 105; p<0.01), However, the portal venous resistance was not significantly different in both groups of rats (3.57+/-0.31 vs. 3.03+/-0.38 dyne sec/cm5 X 105; p>0.05). CONCLUSION: The hemodynamic results of this study indicate that hyperdynamic status of systemic and splanchnic circulation was present in chronic portal hypertension and that the primary factor contributing to the persistently elevated portal venous pressure was the markedly increased portal venous inflow.

Kimura's disease is a benign, uncommon, chronic inflammatory condition that usually presents with painless subcutaneous nodules or plaques. Head and neck are the most frequently involved sites in Kimura's disease. Mandible is the most commonly involved, followed by neck, cheek, scalp and forehead. Other possible sites are oral cavity, inguinal area and extremities, but there have been no reports involving the nose, especially the one that looks like a rhinophyma. We describe a case of Kimura's disease presenting like a rhinophyma.
