A fast parallel solver for the forward problem in electrical impedance tomography.

Electrical impedance tomography (EIT) is a noninvasive imaging modality, where imperceptible currents are applied to the skin and the resulting surface voltages are measured. It has the potential to distinguish between ischaemic and haemorrhagic stroke with a portable and inexpensive device. The image reconstruction relies on an accurate forward model of the experimental setup.

Streptococcus anginosus-constellatus infection of the sternoclavicular joint.

We describe the first reported instance of sternoclavicular pyarthrosis caused by Streptococcus anginosus-constellatus. Infections caused by this organism are unusual in a nonimmunocompromised host. Common conditions predisposing to sternoclavicular joint infection were not present.

Carpal tunnel syndrome as the initial manifestation of tuberculosis.

Two patients presenting with carpal tunnel syndrome as the initial manifestations of tuberculosis were seen during a recent four month period at a larg city-county hospital. Although the clinical picture of the carpal tunnel syndrome was typical, a definite diagnosis could not be made until the time of surgery because of the many other causes of the carpal tunnel syndrome. A review of the experience with musculoskeletal tuberculosis and carpal tunnel syndrome at our hospital indicates that although this combination is not common, it is one of the treatable causes of the carpal tunnel syndrome.

Esophageal varices in Felty's syndrome: A case report and review of the literature.

A case of upper gastrointestinal tract hemorrhage secondary to esophageal varices in a patient with Felty's syndrome prompted a review of the pathogenesis and treatment of this condition. Six previously reported cases of this association were found. The clinical picture is that of long-standing rheumatoid arthritis with severe articular and extraarticular manifestations including splenomegaly, depression of the blood elements, mild liver function abnormalities, portal hypertension without cirrhosis or portal vein obstruction, an elevated splenic blood flow, and a reduction in portal hypertension by simple splenectomy.
