Digital tourniquets: a pressure study with clinical relevance.

This study measured the pressures under the three most commonly used digital tourniquets--the Penrose drain, the rolled rubber glove, and the rubber band. A miniature pressure transducer and a digital strain indicator were used to measure pressures generated by the various tourniquets. The rolled rubber glove technique was highly consistent, irrespective of the clinical experience of the subject, and uniformly generated pressures of less than 500 mm Hg. Pressures generated by Penrose drains and rubber bands were highly variable and were significantly greater than 500 mm Hg. The so-called calibrated Penrose drain generated the highest pressures in the study. The relationship between tourniquet pressures and neurovascular injury in the human digit is not clearly defined.

Tattoo removal: comparative study of six methods in the pig.

Six methods of tattoo removal were compared on tattoos of the same design made on a pig by a professional tattoo artist. Once the tattoos were healed and mature, each method was tried three times at 3-week intervals. Biopsies were taken before and after the treatment was completed to determine the depth of the pigment. Standardized color photographs were used to compare the gross appearance. The six methods of removal tried were (1) split-thickness tangential excision and dextranomer dressings, (2) superficial dermabrasion, (3) dermabrasion and dextranomer dressings, (4) salabrasion, (5) tannic acid solution overtattooing, and (6) CO2 laser. The removal of pigment with tannic acid overtattooing and laser were far more complete than the other techniques. Both techniques left acceptable scars. The overall appearance of the CO2 laser-treated tattoos was deemed the most cosmetically acceptable.

Simplified technique for replantation of the thumb.

Replantation of the thumb is more difficult than that of the fingers since the palmar vessels are out of the plane of the hand. A simplified technique is presented, in which vein graft extensions are anastomosed to the proper digital vessels prior to osteosynthesis. Utilizing this technique, arterial reconstruction can proceed at a more rapid rate with fewer positioning problems.

Lymphaticolymphatic anastomosis.

Lymphaticovenous anastomosis has proved valuable in the treatment of obstructive lymphedema. Histological studies of this anastomosis have shown the lymphatic component to be almost inactive in anastomotic healing. In order to clarify the role of the lymphatics, experimental lymphaticolymphatic anastomoses were performed in canine femoral lymphatics. The technique developed calls for eight to ten 19 mu sutures to prevent vessel wall collapse, and preservation of the vasa vasorum. Vessels were harvested from one hour to six weeks after anastomosis. Scanning electron microscopy and conventional light histology revealed the lymphatics to have active healing of the intima with complete reendothelialization by two weeks. The techniques developed in this study are directly applicable to human lymphaticovenous anastomosis.

Spontaneous rupture of the rectosigmoid colon with anal evisceration: a new complication of uterine prolapse.

Spontaneous large bowel perforations have been associated with chronic constipation. The previously reported episodes of anal evisceration of small intestine have occurred in patients with a rectal prolapse. An end-stage complication of chronic third degree uterine prolapse is presented. A laceration of the anterior rectosignoid colon wall permitted small bowel extrusion through the anus. The tearing effect exerted by the prolapsed uterus at the rectouterine fold presumably caused the rectosigmoid laceration.
