Measurement of upper extremity torque production and its relationship to throwing speed in the competitive athlete.

This study was conducted to establish whether or not a correlation exists between peak torque production of upper extremity (UE) musculature and throwing speed. Eleven professional baseball players were tested for upper extremity peak torque production using a Cybex II Isokinetic Dynamometer. Throwing speed was measured with a radar gun. Results of statistical analysis performed on the data indicate a correlation between shoulder adductors and throwing speed.

Inflammatory pseudotumour of the central nervous system: clinicopathological study of one case and review of the literature.

A 58-year-old male who had been diagnosed as having polymyositis was found to have a mass in the fourth ventricle. This mass showed features of an inflammatory pseudotumour. This lesion has been described in many parts of the body including the central nervous system. This case showed some features different from the previously reported cases in the central nervous system (i.e. presence of necrosis and association with polymyositis) which may throw some light on the pathogenesis of the condition. Inflammatory pseudotumour is most likely to be caused by an exaggerated immunological process and is sometimes associated with high levels of serum immunoglobulin.

Infectious diarrhea in tourists staying in a resort hotel.

An outbreak of infectious diarrhea with 70 laboratory-confirmed cases (58 with Giardia lamblia) and 107 probable cases occurred in U.K. tourists who stayed in a hotel in Greece. After a cluster of six cases in persons who had stayed at the hotel was reported, the Communicable Disease Surveillance Centre began active case ascertainment. This outbreak illustrates the value of an approach to surveillance that integrates routine surveillance data with active case ascertainment.
