Visceral sensation and colitis: inflammation and hypersensitivity do not always go hand in hand.

Visceral sensitivity and inflammation are discussed in relation to novel observations in the current issue of the Journal by Larsson and her colleagues. This paper shows that neither acute nor chronic intestinal inflammation initiated by dextran sodium sulfate is associated with an increase in visceral sensitivity to balloon distension in mice. These findings are discussed in the context of recent work highlighting the role of mast cells, the induction of endogenous antinociceptive pathways and the role of altered bacterial flora in visceral hypersensitivity.

When left-handed mice live in right-handed worlds.

Many C57BL/6J inbred mice were tested for paw preference. In unbiased worlds, approximately 10 percent exhibited lateral preferences inconsistent with the world bias, and males were more strongly lateralized. Influences of world bias appear to be superimposed upon an already laterally dichotomized population. Initial left-right sense, it is posited, arises as an outcome of a seemingly random process.

Invisible hand or fatherly hand? Problems of paternalism in the New Perspective on health.

This article examines the charge that the "New Perspective" on health (as exemplified by the Lalonde Report in Canada, by Prevention and Health in the United Kingdom) represents an abandonment of liberal principles in favor of a collectivist and paternalistic role for the state. It looks first at the problems confronting modern health policy, and at the reasoning behind the New Perspective's approach. It then explores whether and how the charge of paternalism applies to that approach, and just what such a charge implies. The article concludes with a discussion of the "liberal paternalist" viewpoint towards health policy, a viewpoint that combines respect for individual liberty with an interest in taking effective public action to improve the health status of modern populations.

Isolated and painless (?) atrophy of the infraspinatus muscle. Left handed versus right handed volleyball players.

The suprascapular nerve originates from the upper trunk of the brachial plexus or less frequently from the root of C5. It runs a short way and crosses the suprascapular notch. It innervates the supraspinatus muscle and the acromioclavicular and glenohumeral joints. Then, it crosses the lateral edge of the spine of the scapula passing through the spinoglenoid notch, and innervates the infraspinatus muscle. These are potential sites of injury to the suprascapular nerve. Three cases of suprascapular nerve entrapment causing an isolated infraspinatus muscle atrophy in volleyball players were studied. It is suggested the hypothesis that the nature of the smash, in which the athlete uses the arm violently, more than does in volleyball service or in the art of reception, is the key to the pathogenesis of the lesion in volleyball players.

High impulse acceleration levels in hand-held vibratory tools. An additional factor in the hazards associated with the hand-arm vibration syndrome.

The measurement of the root-mean-square (rms) acceleration of vibration does does not take into consideration the short high peak values of the vibratory signal, which may be a hazard contributing to the development of vibration-induced disease. A method for evaluating the impulse character of vibratory signals is given, and impulsiveness is defined as the difference between the peak and rms signals. Measurements were taken during pedestal grinding, during chain sawing with three different generations of saws, and during chiseling with a pneumatic hammer. The measurements comprised (i) analyses done according to the International Organization for Standardization (ISO) draft, (ii) an evaluation of impulsiveness, and (iii) an analysis of the short-time history transient. The risk of vibration-induced white fingers was estimated by the ISO method, and the results were compared with those observed. It was found that the analysis of impulsiveness provided additional data and partly explained the observed symptoms of vibration-induced white fingers. The parameters for the impulsiveness of the vibration signal agreed with the short-time history analysis.
