A retrospective study of allograft bone retrieved from 401 donors between January 1987 and March 1996 was performed to determine the incidence of bacterial contamination. Contamination according to type of donor (live, multiorgan, cadaveric) was also determined. Live donors donating a femoral head demonstrated a contamination rate of 13%; multiorgan donors,(More)
Although leg ulcers have many causes, the most common etiology is venous or arterial insufficiency. The prime objective in the evaluation of leg ulcers is to uncover the precipitating pathologic process, and the first goal of therapy is to correct or control this underlying condition. Simple laboratory tests and office procedures are adjuncts in diagnosis.(More)
A garment worker developed erythema multiforme concurrently with allergic contact dermatitis of the hands. Patch testing revealed sensitivity to nickel (which was present in her scissors) and to paraphenylenediamine (a commercial dye). During the course of the patch-test evaluation, both the hand dermatitis and the erythema multiforme became exacerbated.(More)
Twenty-two patients with 31 leg ulcers of various causes received local wound management consisting of the application of an adhesive hydrocolloid (HC) occlusive dressing (DuoDerm). Group 1 comprised 15 patients (11 outpatients) with 19 ulcers. Approximately two thirds (12/19) of the ulcers healed when treated solely with the HC dressing; mean treatment(More)
We present two unrelated patients with numerous infraocular milium-like lesions that histologically revealed syringoma with many overlying keratin cysts in the papillary dermis. A Fontana-Masson stain revealed no melanin-containing cells in the keratin cyst walls, suggesting that they originated from eccrine ductal structures. A classification of the(More)
Although elective laparoscopic cholecystectomy is today's gold standard for the treatment of symptomatic cholelithiasis, its safety and effectiveness for acute cholecystitis remain controversial. The authors present a retrospective study comparing laparoscopic cholecystectomy in the acute versus the elective setting. A total of 605 patients were treated(More)
From 1950 to 1982, fifteen patients were seen at the Mayo Clinic with a diagnosis of sclerodermoid changes of porphyria cutanea tarda. Fourteen patients had changes similar to scleroderma limited to the skin, and one patient had scleroderma-like skin changes accompanied by visceral abnormalities. Both light-exposed and unexposed areas of the body were(More)
The authors report a study of catecholamine levels in the spinal cords of monkeys following a 300 gm-cm blow to the midthoracic spinal cord. There was a progressive decrease in norepinephrine (NE) activity as a first-order process with a half-life of 6.4 hours. The NE activity in injured tissue never exceeded control levels, which remained unchanged both(More)
Increased serum iodide concentrations secondary to iodine absorption through wounds treated with povidone-iodine dressings is described. Hyperchloremic acidosis and a disparity between serum chloride concentrations determined by two different methods suggested the presence of an unidentified halide. Cardiovascular instability and renal failure occurred(More)
