Post-traumatic pulmonary accumulation of Tc-99m sulfur colloid.

A case is reported in which accumulation of Tc-99m sulfur colloid in one lung occurred following trauma, although the lung remained clear radiographically. Another trauma case is mentioned in which the uptake was bilateral. The cause of this phenomenon is unclear; several potential mechanisms are discussed.

A kinematic analysis of an upper extremity ballistic skill: the windmill pitch.

The purposes of this study were (1) to determine the relative motions of the upper limb segments during the execution of the softball windmill pitch (2) to attempt to determine the effect of these motions on the performance of the skill. High speed motion picture film was used to calculate the kinematic parameters of the pitching arm segments during the pitch. Four highly-skilled pitchers were used as subjects. Each performed at least ten trials of the pitch, which were recorded by two motion picture cameras. The two trials with the fastest ball velocity for each of the four subjects were analyzed from a sagittal aspect only. The resulting kinematic analysis indicated that there was a definite proximal-to-distal sequence of these motions, with decelerations occurring in the proximal segments prior to release of the ball. It was concluded that one of the critical factors in highly-skilled performance of ballistic skills is the ability to decelerate such segments, which likely require very strong eccentric contractions of antagonistic muscle groups.

Vision and sports: a review of the literature.

The basis for training visual abilities to enhance sports performance is explored. Optometric intervention in sports assumes the following statements to be true: 1. Athletes have better visual abilities than non-athletes and better athletes have better visual abilities than the poorer athletes, 2. Visual abilities are trainable, and 3. Visual training is transferable to the performance of the athlete. The literature demonstrates that athletes have better visual abilities than non-athletes. Studies have shown this to be true in the following areas of vision: Larger extent of visual fields, larger fields of recognition (peripheral acuity), larger motion perception fields, lower amounts of heterophoria at near and far, more consistent simultaneous vision, more accurate depth perception, better dynamic visual acuity, and better ocular motilities. The literature also shows that all of the above skills are trainable. Two studies are cited that support the belief that visual training is transferable to athletic performance but they suffer from inadequate experimental design.

Blunt chest trauma: evaluation of the augmented breast.

Breast augmentation is being done increasingly, not only for women who consider their breasts too small but also for those with breast asymmetry, and post-mastectomy patients with reconstruction. It appears inevitable that traumatologists will have to evaluate injury to an augmented breast in a patient who has sustained blunt chest trauma. This paper discusses the differential diagnosis and treatment of implant rupture, hematoma, and spherical capsular contracture as a result of trauma.
