ABSTRACT
BACKGROUND: A 26-year-old male presented with pain in his left tibia. Ultrasonography revealed no abnormalities. Tc-99m-bonescan was requested to rule out stress fracture. The scan confirmed the presence of a left tibial stress fracture, as well as an enhancing lesion in the left parietal bone. The patient had no neurological symptoms.
ABSTRACT
In this report, we present a very rare case of a small bowel GIST arising in a true jejunal diverticulum in a 56-year-old woman.

A case of a histologically proven rhabdoid tumor of the cervical spine in a 19-year-old Caucasian male is presented. Primary extrarenal rhabdoid tumors are very rare. When the central nervous system is involved, the tumor usually is located in the brain. Only three cases of primary spinal rhabdoid tumor have been reported. This case is the first reported extradural rhabdoid tumor of the spinal canal and the first case of a rhabdoid tumor located in the spinal canal with bony involvement.

The effects of piracetam on skin flap viability, capillary blood flow and temperature were studied in abdominal cutaneous flaps in rats. The drug significantly increased the viability of the distal (random) portion of the flap and this response was dose-related. Compared with controls, the area of skin necrosis was 12.4% less in the piracetam-treated animals and extended necrosis was not observed. Piracetam appeared to act by increasing the capillary blood flow, mainly in the distal portion of the flap. The improved perfusion was reflected as a smaller drop in the recorded temperature compared with controls. Blood levels of this drug in animals receiving the maximum effective dose corresponded to the active drug concentration in human rheology.
