Use of immediate postoperative mastectomy prostheses.
From materials readily available in the operating room, a temporary breast prosthesis can be fashioned for use in the immediate postoperative period. These materials yield a prosthesis with good shape and form, filling a brassiere cup and providing the general pressure needed on skin flaps in the immediate postoperative period. Psychologically, filling the absent breast cup helps patients adjust to their new body image and eliminates the shock of gross asymmetry.

Laparoscopic repositioning of malfunctioning peritoneal dialysis catheters.
Continuous ambulatory peritoneal dialysis is commonly used for the maintenance of patients with chronic renal failure. A common complication associated with this treatment is outflow obstruction of the catheter. Noninvasive approaches to outflow obstruction such as enemas, infusions of saline, and body position changes are rarely successful in the management of these complications (1). Herein we report a review of our experience with the use of laparoscopy for the evaluation and management of peritoneal dialysis catheters with outflow obstruction.

Peritoneal dialysis catheter outflow obstruction due to oviductal fimbriae: a case report.
Outflow obstruction is a common cause of peritoneal dialysis catheter malfunction. We report an unusual case of outflow obstruction caused by oviductal fimbriae. Mini-laparatomy and repositioning of the catheter without excising the fallopian tube resulted in good outcome.

Injection of illicit drugs into the granulation tissue of chronic ulcers.
Chronic skin ulcers are rare among healthy young adults. Local injection of cocaine and heroin has been identified as a cause of chronic skin ulcers in young adults abusing intravenous drugs. These patients use both engorged veins surrounding the ulcers and the granulation tissue itself for the injection of drugs. We believe that chronic skin ulcers in young adults should be a marker for intravenous drug abuse, and should be considered in the differential diagnosis of nonhealing wounds.

Metallurgically bonded needle holder jaws. A technique to enhance needle holding security without sutural damage.
A new needle holder jaw face has been specifically designed and developed to increase needle holding security without sutural damage. Tungsten carbide particles have been metallurgically bonded into the stainless steel jaw to create a fine granular surface. This bonded jaw enhances needle holding security by limiting either twisting or rotation of the clamped needle. In addition, compression of the monofilament synthetic sutures by the bonded jaws does not reduce suture breaking strength.

Biomechanics of curved surgical needle bending.
Because needle bending resistance is such an important factor in the selection of surgical needles, a standard quantitative test of needle bending has been devised to study the biomechanics of deformation of needles from three different commercial manufacturers. The superior resistance to deformation of needles made by one manufacturer has been related to the specific alloy, ASTM 45500 stainless steel, employed in its production. The needles produced from ASTM stainless steel 45500 have stronger tensile and yield strengths than those of the other alloys, accounting for their greater resistance to bending.

New atraumatic rounded-edge surgical needle holder jaws.
A new atraumatic smooth needle holder jaw with rounded edges that does not damage synthetic monofilament sutures is described herein. These rounded edges were created by mechanical filing of the sharp edges of smooth needle jaws. Compression of the monofilament suture between the needle holder jaw with sharp edges reduces the suture breaking strength compared with that of control sutures. A quality control method has been devised to detect the potentially damaging sharp edges of smooth needle jaws that can be easily implemented by needle holder manufacturers.

A new quantitative measurement for surgical needle ductility.
Because surgical needle ductility is such an important factor in the selection of surgical needles, a new curved needle ductility test instrument was devised to measure the ductility of needles from three commercial manufacturers. The superior ductility of needles made by one manufacturer was related to the specific alloy, stainless steel ASTM 45500, used in their production. The ASTM 45500 stainless steel has a significantly greater tensile and yield strength than the other stainless steel alloys, accounting for its superior ductility.

Computed tomography diagnosis of acute facial swelling in an adult hemophiliac.
Acute facial swelling can be life-threatening due to airway obstruction. Hemophiliac patients presenting with acute facial swelling must have accurate and expedient diagnosis. We report the case of acute nontraumatic swelling in a hemophiliac patient that was easily and accurately diagnosed by the use of computed tomography scan.

Needle holder damage to surgical needles.
Clamping surgical needles between the jaws of needle holders with teeth markedly weaken the needles, making them prone to breakage. In contrast, clamping surgical needles between either smooth needle holder jaws or jaws embedded with tungsten carbide particles did not alter the ductility of surgical needles.

Splayed handle surgical scissors.
Splayed handle surgical scissors have distinct advantages over conventional scissors that limit hand fatigability. The ringlet configuration of the splayed scissors conforms to the normal resting posture of the hand. In addition, surgeons can apply greater force to the splayed scissor ringlets than that which could be applied to the ringlets of conventional scissors.

Emergency physician's needle holder.
A new needle holder is described that has jaws metallurgically bonded with tungsten carbide particles that enhance needle holding security without causing sutural damage during instrument ties. Scissors have also been incorporated into the needle holder to cut sutures. One ringlet on a handle has been offset to facilitate retrieval of the needle holder from a flat surface.

A new compound curved needle for intradermal suture closure.
A new compound curved needle has been designed and developed for intradermal suture closure from a unique stainless steel alloy, American Society of Testing Materials (ASTM) 45500. This needle has a short, straight, sharpened point with a reverse cutting edge, followed by a curved distal section. Despite its geometry, it exhibited a similar resistance to bending and breakage as did a curved needle with a single radius of curvature manufactured from the same alloy. The design of this new needle enabled the physician to pass it through the dermis with a greater accuracy to a controlled depth and length of bite than curved cutting edge needle with a single radius of curvature.

Emergency medicine magnifying loupes.
A magnifying loupe system has been evaluated for use in emergency medicine. Physicians uniformly preferred a Keplerian lens system over that of the Galilean lens system. The advantages of the Keplerian lens were its increased field of view and its brighter and clearer peripheral image. The Keplerian loupes allowed the physician to visualize the exquisite details of wound configuration and to perform wound closure using microsurgical techniques.

Evaluation of buoyant hydrofitness devices for leg musculoskeletal conditioning.
Air splints have been used for immobilization of fractures, skin graft stabilization and preprosthetic rehabilitation of the amputated lower limb. The purpose of this clinical study was to assess its use as a hydrofitness device to facilitate walking reeducation, to produce muscle strengthening and to increase joint extensibility in patients with weak legs. The performance of the air splint as a hydrofitness device was compared to that of the new foam hydrofitness device. The parameters used to assess the performance of these devices included durability, application and removal times, joint extensibility and the magnitude of the fluid drag forces. On the basis of this evaluation, the performance of the foam hydrofitness device was judged to be superior to that of the air splint for leg musculoskeletal conditioning.

Carburetor burns: preventable injuries associated with high morbidity and frequent litigation.
We have identified carburetor burns as a significant cause of preventable morbidity, both from long-term functional and cosmetic standpoints. The epidemiology of carburetor burns and our experience are described. All of our patients were male, with a mean age of 35 years. Average burn size was 11.3%. The anatomic distribution of these burns, most often on the dominant hand and on the face, contributes to the morbidity of these burns. This injury has been associated with increasingly frequent litigation. We believe that an active education campaign and the addition of warning labels to car engine compartments would make an impact in decreasing the incidence of carburetor burns.
