Cutaneous smooth muscle hamartomas are benign proliferations of smooth muscle bundles within the dermis. They can be congenital or acquired, and most cases are congenital. Congenital smooth muscle hamartomas (CSMHs) usually manifest at birth as well-circumscribed, frequently hypertrichotic, hyperpigmented or skin-colored patches or plaques on trunk or extremities. We report a case of CSMH in a 10 year-old girl, who showed a localized skin-colored patch showing prominent follicular papules on the lateral aspect of her right upper arm, which were found at birth. There was no hypertrichosis and the pseudo-Darier sign was negative. This patchy follicular variant is the less common clinical type of the disease.

Experiments were performed to investigate the effects of pinealectomy on the renin-angiotensin system in Sprague-Dawley rats. The results obtained were as follows. 1) There was no differences of systolic blood pressure, heart rate, water intake, and plasma electrolytes between pinealectomized and sham-operated rats. 2) Renin activity in plasma and pituitary gland did not differ in two experimental groups. 3) The pituitary gland contained the renin activity of about 50pg AI/hr/mg of wet weight. The results suggest that the pineal gland has no correlation with cardiovascular and renin-angiotensin system.

PURPOSE: This study evaluated the minimum ten-year result of primary total hip arthroplasty with a non-cemented Multilock femoral stem. MATERIALS AND METHODS: Fifty five total hip replacements in forty-four patients using a non-cemented Multilock femoral stem and Harris-Galante 2 acetabular component were performed between January 1992 and December 1994. Forty-four hips in thirty-six patients were available for follow up for an average of eleven years (range, ten to twelve years). The clinical results were evaluated based on the Harris hip scores. A detailed radiography analysis was performed by an evaluation of the radiolucent lines, femoral osteolysis, and fixation stability by Engh Method. RESULTS: The average Harris hip score improved from 54.3 points preoperatively to 93.6 points postoperatively. Non-progressive radiolucencies < 2 mm in width were observed in nine (20.5%), and femoral osteolysis was observed in thirteen cases (29.5%). For the fixation stability, osseous ingrowth was noted in thirty nine cases (88.6%) and fibrous ingrowth was observed in two (4.5%). There were three (6.8%) cases with unstable fixation. Two hips underwent revision. The survival rate of the femoral component was 93.2% (forty one cases) after a minimum ten-year follow up. CONCLUSION: The non-cemented Multilock femoral component provided excellent clinical and radiographic results. However, the rate of femoral osteolysis was relatively high (mostly restricted to zone 1 and 7).

PURPOSE: The most important step for patients who come to the emergency department with ureter stones is acute pain management. There have been insufficient studies on what factors affect acute pain management for ureteral colic the most. In this study, patients with ureteral colic were divided into two groups: one group, in which the pain was first managed with an analgesic, and another group with unmanaged pain, to find factors that most affect additive analgesics administration for ureter stones. METHODS: There were 121 patients, eventually confirmed for the presence of ureter stones through a computed tomography CT scan, included in this study. When ureter stones were suspected after the initial patient evaluation, initial pain was assessed through numerical rating scale (NRS) and the first analgesic was administered once. Pain was reassessed through NRS after 30 minutes. At that time, if the pain was managed, the patient was assigned to Group 1. If the pain persisted, another analgesic was administered for the second and third time, and the patient was assigned to Group 2. Finally, ureter stones were identified through CT scan. RESULTS: There were 58 patients (47.9%) in Group 1 and 63 patients (52.1%) in Group 2. There were no statistically significant differences in average age, serum creatinine, size of ureter stone, and severity of hematuria between the two groups. The differences in NRS measured initially and after 30 minutes were statistically significant (7.6+/-1.4 vs. 8.6+/-1.2, p<0.001; 1.4+/-1.3 vs. 6.6+/-1.9, p<0.001, respectively). The presence of hydronephrosis and perirenal edema were also statistically significant (p<0.001, p=0.007). The affecting factor for the administration of additive analgesics was hydronephrosis (odds ratio 7.213, p<0.001). CONCLUSION: Hydronephrosis is an important factor in the treatment of patients with additive analgesics. It can also be used as a predictive index to assess the severity of pain in patients with ureter stones.

PURPOSE: To investigate the factors which influence on the fixation failure after the compression hip screw fixation for unstable intertrochanteric fractures. MATERIALS AND METHODS: Eighty-two patients of unstable intertrochanteric fracture of A2 and A3 type who had underwent operation with compression hip screw were evaluated at least 1 year follow-up in regard to the age, degree of osteoporosis, fracture type, diastasis of fragment, sliding of lag screw, position of lag screw and status of reduction. RESULTS: 73 patients out of 82 patients had the union and 9 patients showed fixation failure. The results of fixation failure were 6 cases of migration of lag screw and 3 cases of cut-out of lag screw. There were statistically significant correlations between fixation failure and A2.3 and A3 type. The fixation failure group showed increased medial migration of medial cortex of proximal and distal fragment, which is significantly correlated with fixation failure. There were little statistical significant correlations between age, degree of osteoporosis, status of reduction, position of lag screw, sliding of lag screw and fixation failure. CONCLUSION: Another alternative fixation method and technique have to be considered for unstable A2-3 or A3 type because compression hip screw fixation only is very insufficient with high failure rate.
