Parenteral nitrogen mustard for inflammatory arthritis.

A patient with progressive psoriatic arthritis refractory to methotrexate therapy was treated empirically with intravenous nitrogen mustard, or HN2. His response to therapy was compared with the responses of five rheumatoid arthritis patients treated with the same regimen. At 14 days after therapy was begun the patient with psoriatic arthritis showed significant improvement, at least comparable to that observed in the rheumatoid arthritis group. Intravenous HN2 therapy may be an alternative to methotrexate for progressive psoriatic arthritis.

Sarcoidosis of the female genital tract: a case presentation and survey of the world literature.

Sarcoidosis of the female genital tract is a rare clinical entity with only 20 cases reported in the world literature to date. An additional case is presented with a review of the previously reported cases. The diagnostic and histologic aspects of the disease are also discussed. The presence of granulomatous diseases in the female genital tract should initiate a thorough investigation for potential etiologies by both the pathologist and clinician. Etiologies of granuloma fraction must include coccidiomycosis, foreign body reactions, lymphogranuloma inguinale, and tuberculosis. Bacteriologic proof is essential to differentiate these from sarcoidosis.

Evaluation of smoking-induced effects on sympathetic, hemodynamic and metabolic variables with respect to plasma nicotine and COHb levels.

The effect of smoking cigarettes containing 1.5 mg and 0.08 mg nicotine per cigarette and of sham-smoking was studied in six healthy habitual smokers. Levels of carboxyhemoglobin (COHb) and plasma nicotine were measured simultaneously with hemodynamic variables, such as heart rate and blood pressure, and with the metabolic parameters, plasma DBH, cortisol, blood glucose, lactate and free fatty acids. All variables, with the exception of COHb are dose related to plasma nicotine levels. Blood pressure, heart rate and lactate show simultaneous peaks together with maximal nicotine levels, while DBH and cortisol, blood glucose and free fatty acids show a delayed reaction compared to nicotine concentrations. No effects of COHb, even with levels up to 5.6 +/- 0.5% have been observed on the variables investigated. These results demonstrate, that it is nicotine which induces considerable hemodynamic and metabolic alterations after smoking.

[Abdominal computer tomography].

In computer tomography of the abdomen the amount of diagnostic information obtained depends on the organ system examined and correlates with the topographical anatomy. The information gained by this non-invasive method results from the demonstration of contour alteration and from inherent density differences. Although at this point in time, while the process of evaluation is still in progress, it is too early to formulate definitive guidelines on the indications for computer tomography of the abdomen, we suggest, on the basis of experience hitherto, that computer tomography of the adrenals and the pancreas is better than the previously known image-producing diagnostic methods. The overall diagnostic value of computer tomography of the liver and spleen, depending on the pathology in question, is apparently at least equal to sonography, nuclear medicine and angiography. Computer tomography of the gastrointestinal tract and the kidneys, when compared to other diagnostic radiographic and sonographic investigations, at present adds little information, and for this reason has limited application in these systems. In contrast to this is the highly instructive computer tomographic examination of the extrarenal retroperitoneal space.
