We present the case of a woman in her 70s who was diagnosed with rheumatoid vasculitis (RV) after initially presenting with systemic joint pain and erythema. RV, a rare complication of rheumatoid arthritis, involves inflammation of blood vessels, leading to various skin manifestations. The patient's complaints included fever, generalized joint pain, and skin manifestations that initially resembled erythema multiforme.

A 65-year-old man was diagnosed as lumbar spinal canal stenosis and scheduled for operation. Preoperatively, he had chronic renal failure, mild aortic valve stenosis, and moderate mitral valve regurgitation.

An experimental study was performed to estimate the degree of corneal endothelial damage caused by ultrasound during phacoemulsification. Cultured corneal endothelium prepared from bovine eyes was exposed to ultrasound. Dead cell rates were determined by counting the number of cells positively stained by trypan blue under various conditions of ultrasonic radiation.

We designed an inductive aperture-type applicator, IATA, consisting of a one-turn, square, column-like coil made of a metal strip. In experiments using a phantom, this applicator was seen to have the following characteristics: (1) it does not excessively heat the fat layer; (2) deep portions can be heated effectively; (3) heat can be applied to the subject, without contact with the applicator; (4) excessive generation of heat does not occur in parts of tissue near the edge of the aperture; (5) size of the aperture can be changed for adaptation to size of the site to be heated; (6) the aperture can be modified to fit the shape of the subject and the depth of penetration is influenced by size of the subject being heated; (7) the applicator can be driven at an arbitrary frequency; (8) efficiency of heat generation to the input power is low. The inductive heating equipment, 'Inductron', which we have developed possesses the necessary requirements for adequate clinical application.
