A surgical approach to the motor branch of the ulnar nerve.

Isolated injury to the motor branch of the ulnar nerve is a relatively rare injury, often initially misdiagnosed. If repair is attempted through the original laceration without complete motor branch exposure, results can be less than satisfactory. A recent case illustrates this injury and provides us with an opportunity to review the surgical anatomy of the motor branch of the ulnar nerve. The surgical approach to the motor branch has been detailed and specifically emphasizes complete motor branch exposure from the main ulnar nerve trunk to the most distal motor branch entry into the adductor pollicis muscle. This approach permits definition of the exact level of the nerve injury, preservation of any intact proximal fine motor branches, and facilitates the mechanics of nerve repair.

Treatment of keloids by combined surgical excision and immediate postoperative X-ray therapy.

Sixty-eight histopathologically confirmed keloids were excised in 40 patients from 1970 to 1979. Surgery involved intrakeloidal excision with wound closure by direct, multilayered advancement repair or split-thickness skin grafting. All patients received x-ray therapy totaling 1,500 rads delivered in 3 equal doses, the first within several hours after surgery and the rest at two- to three-day intervals. There was a minimum of one year's follow-up in all cases, with a mean follow-up time of approximately twenty-four months. Recurrence rates of 21% per lesion and 28% per patient were obtained for the series. Earlobe keloids had recurrence rates similar to those noted for the series of a whole. Seventy-five percent of recurrences were evident within twelve months following treatment. Intrakeloidal excision combined with immediate postoperative x-ray therapy is effective in treating keloids.

Topical and systemic antimicrobial agents in burns.

Infection is the major cause of morbidity and mortality in burns. Burn wound infection is defined as burn wound bacterial proliferation in a density equal to or greater than 10(5) bacteria per gram of tissue. Gram-negative bacteria, notably Pseudomonas aeruginosa, as well as staphylococci and fungal opportunists, have been identified as prominent invaders. Topical and systemic antimicrobial agents are essential adjuncts in the prevention and treatment of burn wound infection. Topical antimicrobial therapy is indicated in all hospitalized burn patients. Short-term use of systemic antimicrobials for prophylaxis and treatment is required in all moderate and major burns, specifically for early prophylaxis, perioperative prophylaxis, and clinical infection. Antimicrobial choice is based on specific patient or environmental bacteriological data.
