We experienced a case of venous hemangioma occuring on the inner aspect of right forearm of 40-year-old woman. The skin lesion was slight tender, pea sized, dark brown surfaced, subcutaneous mass. The entire dermis was filled with numerous coiled thick walled vessels surrounded by fibrous stroma on the histopathologic examination. The wall, lined by a single layer of endothelial cells, lacked elastic fibers on the specimen of Verhoeff-Van Gieson and Massons trichrotne stains.

Leiomyoma Cutis is an unusual benign tumor of smooth muscle derivecl either from the arrector pili muscle, from the media of blood vesseles, or from smooth muscles of scrotum, labia or nipple. Two casea of leiomyoma cutis confirmed by H&E stain and Massons stain is presented, one with lesion on the left thigh and the ather with lesion of the left ankle. The first case was a 49 year-old female with solitary pinhead sized subcutaneous firm mass with intermittent pain and tenderess for 10 months, The second case waa a 36 year-old female with painful solitary peanut sized firm nodule which had pinkish center of 1 year duration.

OBJECTIVES: The aim of this study was to evaluate the differences in patients with positional dependent sleep apnea according to their non-supine apnea-hypopnea index (AHI, > or =5 vs. <5). METHODS: 92 patients with positional sleep apnea were evaluated. The patients were divided into two groups : group I was non-supine AHI having > or =5 ; group II was non-supine AHI having less than 5. Statistical analysis was performed to find the difference between two groups. RESULTS: In 92 patients, the number of group I patients was 11 (12%) and the number of group II patients was 81 (88%). In the severe AHI group, percentage of group I was dominated (70%) and showing a significant difference compared with the mild and moderate AHI groups (p<.05). In the severe body mass index (BMI) group, percentage of group I was dominated (54.5%) and showing a significant difference compared with of the mild and moderate BMI groups (p<.05). The percentage of group I was significantly higher than group II (p<.05) in the AHI, supine AHI, non-supine AHI and snore time. CONCLUSIONS: In patients with positional sleep apnea, severe OSA and high BMI are more common in patients with non-supine AHI> or =5 than non-supine AHI<5.

Abutment screw loosening of implant restorations is a common problem in the treatment of dental implant. The purpose of this study was to calculate stress and preload from the elongation measurements and to determine maximum tightening torque without plastic deformation of the screw. The length of each gold alloy UCLA screw was measured after tightening to the manufacturer's recommended torque of 32 N-cm. Similarily, titanium UCLA screws were measured after tightening to the manufacturer's recommended torque of 20 N-cm. Loosening torque was also measured after tightening to 32 N-cm torque for gold alloy abutment screws and 20 N-cm for titanium abutment screws. The results were as follows ; 1. There was a regressive relationship between screw elongation and tightening torque (gold alloy : r2 = 0.987, titanium : r2 = 0.978), and the mean preload calculated from elongation measurements was 501.11 +/- 26.85 N (gold alloy) and 399.43 +/- 7.61 N (titanium). 2. Stress calculated for the gold alloy and titanium screws at maximum recommended tightening torque was less than 60% of their respective yield strengths and within the elastic range. Maximum tightening torque without plastic deformation was 61 N-cm(gold alloy) and 39 N-cm(titanium). 3. For titanium screws, there was a significant difference between loosening after trial 1 and loosening after trials 2 to 5 (p<0.05). No statistically significant difference was seen in mean loosening torques between the first and subsequent trials for gold alloy screws.

We present herein a case of painless piezogenic pedal papules occurring on the both heels of 25-year-old female patient, Histopathologic findings showed normal adipose tissue surrounded by loose fibrous tissue in the nid-dermis and thickening of venous wall. Hyalinized thick collagen bundles were distributed below the herniated adipose tissue in the nodular pattern. Her parents, one brother and sister had the sarne clinical features.
