BB and pellet guns--toys or deadly weapons?

BB and pellet weapons are not included in gun control laws and are often sold as children's toys. Injuries caused by these weapons have been considered trivial unless they involve vulnerable surface organs such as the eye. The purpose of this study was to review the management of six cases of pellet or BB gun injuries that required abdominal exploration at the University of South Alabama Medical Center from January 1980 through June 1982. Five of the six patients had significant internal injuries including perforations of the stomach, jejunum, liver, and pancreas. The ballistics of pneumatic weapons are reviewed. The muzzle velocities of many of these weapons necessitate that wounds caused by these weapons be handled with the same principles as for any small-caliber, low-velocity (less than 1,200 feet/second) weapons. Public education programs are urgently needed to educate parents as to the potential danger involved in purchasing these weapons for unsupervised use as toys by children.

Retinofugal pathways from albino eyes embryonically transplanted to normal and albino axolotls.

Albino axolotl eyes were transplanted embryonically to normal and albino axolotl hosts. The animals were allowed to mature for several months and then their transplanted eyes were injected with tritiated proline. The projections from these albino eyes were compared with those obtained from similar transplants of normally pigmented eyes. Special attention was paid to the crossed and uncrossed components of the projections. No differences were found between normal and albino transplants. These results indicate that abnormal retinofugal crossing, which results from a lack of pigmentation in the mammalian eye, does not occur in the axolotl even when the fraction of retinal cells projecting ipsilaterally is experimentally increased by transplanting supernumerary eyes into embryos.

A nurse rehabilitator's impact on patients with myocardial infarction.

A nurse rehabilitator, supplementing routine physician/nursing coronary care unit (CCU) care, was found to be effective in increasing the return to work rate (p less than .05) and decreasing smoking (p less than .05) in a randomized trial of 102 patients with acute myocardial infarction (MI). These outcomes were thought to be due to the nurse rehabilitator's efforts in increasing patient knowledge of heart disease (p less than .01) and individual counseling.
