Tibial artery false aneurysm: uncommon result of blunt injury occurring during athletics.

Two young men presented with symptoms following lower extremity injuries sustained in the normal course of participation in sports. One played baseball while the other competed in Tae Kwon Do. One case presented with digital ischemia, the other developed a pulsating hematoma.

Hepatic acute phase protein synthesis is indirectly regulated by tumor necrosis factor.

It has been proposed that tumor necrosis factor (TNF) is a direct regulator of postinjury hepatic protein synthesis. To test this hypothesis we investigated the total protein and specific acute phase protein synthesis response of murine hepatocytes to stimulation with mu-rTNF-alpha in vivo and in vitro. Total hepatocyte secretory protein synthesis was assessed by incorporation of [35-S] methionine into TCA-precipitated protein; and acute phase protein synthesis was assessed by induction of a 23-kD acute phase protein marker and by suppression of albumin synthesis determined by SDS-PAGE and autoradiography.

Focal histiocytosis X of the parietal lobe. Case report.

The authors describe a case of histiocytosis X of the parietal lobe presenting as a space-occupying lesion on a computerized tomography scan of the brain. The clinical, radiographic, and therapeutic aspects of the case are discussed. A brief review of the literature is presented.

Gray scale ultrasound: evaluation of iliopsoas hematomas in hemophiliacs.

Because of its insidious nature, intramuscular bleeding, in contrast to hemarthrosis, is missed or belatedly recognized in hemophiliacs. Sixteen patients with suspected iliopsoas bleeding were studied by gray scale ultrasonography. In 12 patients it was possible to confirm the diagnosis of iliopsoas hematoma because of enlargement and rounding of the psoas muscle.

Meat bolus impaction of the lower esophagus associated with a paraesophageal hernia. Successful noninvasive treatment with intravenous glucagon.

Ferrucci and Long recently reported the relief of esophageal food impaction with the use of intravenous glucagon in three patients. Our first experience in using this new procedure was very successful and gratifying. The essence and purpose of this brief communication is to record and further substantiate the efficacy of a new treatment modality.
