Bacterial studies of leg ulcers.

--Bacteriologic studies of 30 chronic leg ulcers were studied in 18 adult patients before and after treatment with a local cleansing agent, Debrisan.--Results show that all ulcers, whether clinically inflamed or not, are secondarily infected.--The majority of ulcers grew more than 1 type of organism, up to 6 different types in 1 single ulcer.--The use of Debrisan reduces the types of organisms and colony counts in ulcers, allowing healthy granulation and epithelialization to proceed normally.--Control of infection reduces surrounding local edema and erythema.--By reducing types of organisms and colony counts in chronic leg ulcers successful skin grafting was readily achieved.

Basilic vein to brachial artery fistula: a new access for chronic hemodialysis.

A new vascular access for chronic hemodialysis is developed by creating a fistula in the upper arm between the end of the relocated basilic vein and anterior aspect of the brachial artery. The procedure has been used 24 times in 23 patients over the past 15 months (average eight months) with minimal complications and low failure rates. This fistula provides a straight, long, easily accessible conduit with high flows; it has only one vascular anastomosis and maintains the anatomic continuity of its venous end with the axillary vein. It also obviates the need for autologous, prosthetic, or heterografts. The procedure is indicated when suitable vessels in the forearm have been exhausted or are unavailable. However, additional clinical trials and continued long-term follow-up are necessary for more definite conclusions.

Early detection of acute rejection in renal allografts using radioiodinated autologous fibrinogen.

131I-labeled autologous fibrinogen was used to detect acute renal allograft rejection in the early postoperative period. Ratios of radioactive counts over transplanted kidneys to those over the heart increased with deposition of radioactive fibrinogen in kidneys undergoing rejection. The test was positive in all instances of acute rejection twelve to twenty-four hours prior to clinical ro biochemical changes. False-positive test results were noted in instances of perinephric hematoma, seroma, and wound abscess and in one patient with urinary tract infection. The test was negative in cases of renal failure secondary to acute tubular necrosis, uric acid nephropathy (in the absence of acute rejection), and chronic rejection. This test is simple, rapid, and practical. It can be performed at the bedside and is free from complications, particularly serum hepatitis.
