Synovitis in secondary syphilis. Clinical, light, and electron microscopic studies.

Polyarthritis and tenosynovitis were seen as the presenting complaints in 7 patients with secondary syphilis. Synovial needle biopsy was obtained in 3 cases and showed mild synovitis with infiltration by lymphocytes, plasma cells, and polymorphonuclear leukocytes; vascular congestion; and slightly increased synovial lining cells. In addition, electron microscopy in these synovial membranes showed many necrotic polymorphonuclear leukocytes, much interstitial debris and fibrin, and in 2 patients, bodies suggestive of Treponema pallidum in the interstitium and in vessel lumens.

Is it possible to reduce tobacco consumption via alcohol taxation?

Recent studies with Spanish data suggest that indirect taxation is a potential instrument to reduce tobacco consumption but the magnitude of the estimated price elasticity limits the effectiveness of the taxes. However, if the separability restriction does not hold between tobacco and other goods, the results obtained could be misleading. This shortcoming of previous analyses leads us to formulate a demand system with alcohol, tobacco and other goods so as to estimate and test complementary effects and to assess the possibility for reducing consumption by indirect taxation of complementary commodities. We use the Spanish Family Expenditure Survey to carry out a cross-section study which allows us to estimate demand models under different assumptions about the nature of zero expenditures and to test the effectiveness of indirect taxation. The findings tend to support our initial suspicions about the inadequacy of imposing separability and point out the importance of alcohol taxation to reduce tobacco consumption. However, given the structure of the data used, these results should be viewed with caution and must be confirmed by additional evidence.

A study of sensory recovery following carpal tunnel release.

The purpose of this study was to define the testing parameters that are most sensitive to sensory loss in carpal tunnel syndrome and then to track recovery of these sensations postoperatively. Two dozen patients underwent standard nerve decompression and were subsequently re-evaluated at six weeks, three months, and six months. The test battery included provocative maneuvers, light-touch threshold determined by manually applied monofilaments and skin indentation with the Automated Tactile Tester (ATT), manual two-point discrimination, manual high-frequency vibration and ATT low-frequency vibration, and ATT warmth detection. The most sensitive indicators of sensory abnormality were the ATT low-frequency vibration and skin indentation tests. Responses to all but these two tests returned to normal within two months postoperatively. The ATT indentation and vibration tests showed continual improvement over the study period, returning to nearly normal values by six months. Recommendations concerning the use of automated methods for testing sensory function are made in light of these findings.
