Isolated anterior dislocation of the proximal tibiofibular joint.
Three cases of isolated anterior dislocation in the proximal tibiofibular joint are presented. The common aetiological feature was that injury occurred with the knee in hyperflexion and the foot inverted and extended. The symptoms of locking, pain and giving way may lead to an erroneous diagnosis of meniscal injury. Early diagnosis in the acute case enabled easy reduction. In the inveterate cases, resection of the head of the fibula gave complete relief of symptoms.

Therapy of infections with cefazolin.
16 patients with acute urinary tract infections, 6 with acute lower respiratory tract infections and 3 with miscellaneous infections were treated with 1 g cefazolin parenterally 3 times daily. All patients, except one in whom therapy was discontinued, were cured. Both intramuscular and intravenous administration resulted in high-peak serum levels, and concentrations after 8 h were still inhibitory to relevant pathogens. The drug was well tolerated and caused, after intramuscular injection, probably less pain than does cephalotin. Cefazolin is a rational choice of therapy in severe cases of acute urinary, respiratory, and other infections.

Multiplane transesophageal Doppler echocardiographic measurements of the velocity profile in the human pulmonary artery.
Eight healthy, unsedated volunteers were studied to introduce a new non-invasive method for detailed blood velocity measurements and to evaluate flow patterns in the human pulmonary artery during end-expiratory apnea. With a multiplane transesophageal ultrasonic probe, spectral Doppler velocity registration was performed in nine different spatial locations across the vessel area. The pulmonary trunk could be visualized in all patients. The mean temporal velocity profile was virtually flat despite an instantaneous skewness that rotated counterclockwise up to 180 degrees. Furthermore, our data indicate that a good estimate of the temporal and spatial mean velocity can be obtained from velocity recordings based on centrally placed sample volumes. This makes the future application of Doppler-based measurement of cardiac output in the pulmonary artery hopeful. The ability of multiplane transesophageal echocardiography to estimate the area of the elastic human pulmonary artery, however, has to be evaluated more extensively before the clinical importance of this tool for measurement of cardiac output can be established.
