Computed tomography of thymic abnormalities.

Computed tomographic examinations of 38 patients with surgically and histologically proven diagnosis were reviewed. Twenty subjects (52%) had an invasive thymoma and 16% an hyperplasic thymus. Myasthenia gravis was present in 6 cases (16%) of thymic abnormalities, four (10.

[Evaluation of pathology of the small intestine by computed tomography. Apropos of 34 cases].

A retrospective study reviewed computed tomography imaging findings in 34 patients with affections of the small intestine. In 68% of cases lesions were demonstrated by the CT scan before any other investigation. Whether the lesions were benign or malignant tumors, inflammatory or infectious disorders or malformations, all images showed segmental or localized parietal thickening of 5 mm or more.

Adjusted versus fixed-dose subcutaneous heparin in the prevention of deep-vein thrombosis after total hip replacement.

Venous thromboembolism after total hip replacement continues to be a serious problem. We conducted a study to determine whether adjustment of the dose of subcutaneous heparin to yield partial thromboplastin times in the high-normal range results in a greater reduction of postoperative deep-vein thrombosis than fixed doses of heparin. Seventy-nine patients undergoing elective hip arthroplasty were randomly divided into two groups two days before surgery.
