Use of prostheses and footwear in 110 inner-city partial-foot amputees.

The number of partial-foot amputations performed is increasing, and many recommendations have been made regarding the use of prostheses and footwear designed to prevent higher-level amputations in this population. The present study investigated the use of prostheses and shoe inserts and the types of footwear worn by partial-foot amputees in the inner city to determine whether previous recommendations are being followed as well as whether new prosthetic styles are being used. The study surveyed 110 patients (73 men and 37 women) with a mean age of 58.6 years (range, 21 to 86 years) with partial-foot amputations of all levels. The results showed that about one-half of all patients wore a shoe-insert orthosis. Although 54% wore some form of special footwear to accommodate and protect the residual foot, no patient in this study wore a shoe with a rocker-bottom sole. Only one patient with a transmetatarsal amputation used a brace and only one patient in the entire study wore a modern cosmetic foot prosthesis.

Rapid detection of streptococcal pharyngitis.

The authors discuss the controversy relating to treatment of streptococcal pharyngitis. They describe the kits now available for screening for this disorder, and their advantages, disadvantages in terms of patient welfare, cost effectiveness, and demands on staff. Sensible management and advice on the use of these kits is offered to the office practitioner.

Laboratory and clinical evaluation of isolation media for Campylobacter jejuni.

Six selective isolation media were evaluated for their ability to support the growth of Campylobacter jejuni. Colony counts of 70 isolated strains of C. jejuni and recovery studies on these strains in simulated positive feces samples demonstrated that Bolton and Hutchinson' charcoal, cefoperazone, deoxycholate agar and Karmali's charcoal-based selective medium produced the highest recovery rates with the greatest suppression of other fecal flora. C. jejuni colonies were more easily recognized on charcoal-based selective medium. A clinical evaluation performed on 2,780 human, animal, and avian feces specimens confirmed the results of the laboratory investigation. From human samples, 4 more strains of C. jejuni were isolated on charcoal-based selective medium than were isolated on Skirrow medium, and 19 more strains of C. jejuni or C. coli were isolated on charcoal-based selective medium from animal specimens. Suppression of normal fecal flora was also greater on charcoal-based selective medium.
