MRI visualization of bilateral quadriceps tendon rupture in a patient with secondary hyperparathyroidism: implications for diagnosis and therapy.

Many musculoskeletal conditions have in the past been best defined on a clinical basis. However, because of pain, limitation of motion and hematomas, tendon ruptures can often be misdiagnosed clinically and it would be quite helpful to the clinician to have a noninvasive imaging technique. This communication defines the role of MRI in the early diagnosis of a nontraumatic rupture of the quadriceps tendons bilaterally in a patient with renal failure and known secondary hyperparathyroidism. The imaging techniques accurately defined the presence of hemorrhage extending into muscle from the ruptured tendons as well as the actual site and extent of tendon rupture. Since tendons have low mobile proton content and have low signal on MRI--disruptions are easily seen--MRI is the ideal noninvasive imaging technique for tendon injury, acute.

Treatment of herpes zoster and postzoster neuralgia by subcutaneous injection of triamcinolone.

Based on a study of 400 patients (272 patients with herpes zoster and 128 with postzoster neuralgia), the subcutaneous injection of triamcinolone in saline is concluded to be a safe and effective measure for reducing pain. The acute eruption and symptoms of herpes zoster cleared in an average of less than four days. Postzoster neuralgia developed in only 2.9% of the patients, although nearly 70% of these patients were more than 50 years of age. In cases of postzoster neuralgia, 35% cleared completely; 28.9% improved enough so that they could live with the occasional pain, itching, or numbness, and therapy was not beneficial for an additional 15.6%, and it failed in 18.7% of the cases. The results were satisfactory in 63.9% of the patients, and the side effects were minimal.

Review of calcium methodologies.

A review of calcium methodologies for serum has been described. The analytical systems developed over the past century have been classified as to type beginning with gravimetry and extending to isotope dilution-mass spectrometry by covering all of the commonly used technics which have evolved during that period. Screening and referee procedures are discussed along with comparative sensitivities encountered between atomic absorption spectrophotometry and molecular absorption spectrophotometry. A procedure involving a simple direct reaction for serum calcium using cresolphthalein complexone is recommended in which high blanks are minimized by repressing the ionization of the color reagent on lowering the dielectric constant characteristics of the mixture with dimethylsulfoxide. Reaction characteristics, errors which can be encountered, normal ranges and an interpretative resume are included in its discussion.
