[EX Q]: Abstract: In this report, 11 cases of angiosarcoma of the head and neck are reviewed. The patients ranged in age from newborn to 78 years; mean age was 64 years. There were eight men and three women. Sites of involvement included the scalp and forehead, cheek, nose and ethmoid sinuses, neck, and mandible. Surgery was the primary method of treatment. The 2-year survival rate was 50% (5/10) and the 5-year survival rate was 22% (2/9). Regional metastases were seen in 18% (2/11). We found that the tumors were poorly circumscribed and spread horizontally within the dermis for considerable distances, especially in the scalp. Total surgical excision using frozen section control before reconstruction may offer the best chance for control of disease.

[EX Q]: Abstract: Seventy two patients (39 women) with colonic adenomas were compared with 72 adenoma free controls (39 women) to investigate the possible association between previous cholecystectomy and the subsequent development of adenomas. Data were gathered retrospectively from medical records. Overall there was no significant association between colonic adenomas and previous cholecystectomy. When women are considered separately, however, eight cases and no controls had undergone cholecystectomy (odds ratio infinity lower 95% confidence limits 1.7, p greater than 0.01). No association between previous cholecystectomy and large bowel adenomas was found in men. Four of nine (44.4%) women with right sided colonic adenomas had undergone previous cholecystectomy compared with only three of 23 (13%) women with left sided adenomas.

[EX Q]: Abstract: A technique for ipsilateral femoral neck and shaft fracture using the sliding compression hip screw with plate combined with trochanteric antegrade Ender nailing of the femur was applied in two cases. Ender nails can be passed without difficulty past a compression hip screw and the bicortical plating screws. The hip and femur can be fixed internally through a single approach in a single position. Sliding compression hip screw devices can provide excellent preliminary stable femoral neck fixation. Blood supply to the femoral head is not disturbed while the femoral intramedullary fixation is performed. Antegrade Ender nailing avoids the common knee complications associated with other retrograde techniques. Decreased operative time, less blood loss, less technical difficulty, and early mobilization are important factors in the multiple-injured patient. Femoral intramedullary fixation may require open reduction, circlerage to ensure stability, and maintenance of alignment in case of significant comminution to allow early crutch ambulation. This mode of fixation may be advantageous for selected cases.
