Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

PURPOSE: The purposes of this study were to examine differences in depression and smartphone addiction among four styles of perceived parenting, and determine whether the perceptions of paternal and maternal parenting are associated with depression and smartphone addiction among college students. METHODS: A cross-sectional descriptive correlational design was used. A convenience sample of 378 undergraduate students responded to the survey. Data were analyzed using ANOVA, Pearson correlation, and multiple regression with IBM SPSS statistics version 21. RESULTS: Levels of depression and smartphone addiction were significantly different according to the four styles of perceived parenting (optimal parenting, affectionate constraint parenting, affectionless control parenting, and neglectful parenting). Scores of depression and smartphone addiction in the group with perceived affectionless control parenting were higher than those in the other groups. In a regression model, maternal care and paternal overprotection were significantly associated with depression. Also, maternal overprotection was the only significant predictor of smartphone addiction. CONCLUSION: These results suggest that students who perceive that both fathers and mothers are low in care, warmth, and support; but high in overprotection, control and intrusiveness are vulnerable to depression and smartphone addiction. Targeted interventions to change and reframe students' perception of paternal and maternal parenting in a positive way may reduce their depression and smartphone addiction.

The purpose of this study was to compare the dento-skeletal characteristics between functional and skeletal anterior cross-bite patients. Twenty-eight functional anterior cross-bite patients and thirty-one skeletal anterior cross-bite patients were selected as a test and a control group. Mean ages of the test and the control group were 9.6+/-1.8 and 9.8+/-1.9, respectively. Lateral cephalograms were taken. Forty-nine cephalometric variables were measured and statistical analysis was performed to find the morphological differences between the groups. Statistically significant differences were found in the cephalometric variables of cranial deflection, maxillary depth, ANB, convexity, NPo-AB, APDI, Mx 1-SN, Mx 1-NA angle, Mx 1-NA, Md 1-NB angle and Md 1-NB. The test group showed more Class III growth potential, more protruded maxilla, lesser maxillo-mandibular difference, more uprighted and retruded maxillary central incisor, more labially tipped and protruded mandibular central incisor.
