Fractures in women lacrosse players: preventable injuries.
Women field-lacrosse players, except the goalkeeper, do not wear protective equipment and are therefore susceptible to bony injuries by either the lacrosse stick or ball. The purpose of this article is to document one case of a finger fracture and another of a nasal fracture caused by an impact injury from lacrosse sticks in women field-lacrosse players. The Consumer Product Safety Commission estimates that 73.6% of the fractures in women field-lacrosse players that occur annually are located in the head, face, hand, or fingers. These injuries could be easily prevented by protective equipment (face mask or helmet) or gloves.

Commotio cordis in a lacrosse goalie.
A case of commotio cordis has been documented in a male lacrosse goalie. The development of this injury is attributed to a defect in the design of the lacrosse chest protector. Insufficient foam padding over the sternum makes the goalie vulnerable to cardiac concussion. An improvement in the design of the chest protector is now being instituted by the manufacturers that should prevent this serious injury.

Performance of new wound closure tapes.
The purpose of this study was to determine the performance of six different wound closure tapes using a battery of standardized tests that included breaking strength, elongation, air porosity, and shear adhesion. The results of these tests were incorporated into a ranking system that provided an index of the overall performance of each tape. Because Nichi-Strip, Curi-Strip and Steri-Strip wound closure tapes achieved the highest rankings, we recommend their use in the emergency department.

Anesthetic properties and toxicity of bupivacaine and lidocaine for infiltration anesthesia.
The purpose of this study was to measure the toxicity and anesthetic properties of two anesthetic agents, bupivacaine and lidocaine. These anesthetic agents did not damage tissue defenses or invite infection in experimental animals. In addition, the pain of subdermal injection, the onset of anesthesia, and the frequency of satisfactory anesthesia in human volunteers were remarkably similar. Because the duration of anesthesia induced by bupivacaine was nearly four times longer than that by lidocaine, bupivacaine is recommended for infiltration anesthesia of lacerations treated in the emergency department.

Influence of cutting edge configuration on surgical needle penetration forces.
A standardized test for measuring the needle penetration forces has been developed that can be easily replicated in any laboratory. Using this test, conventional cutting edge needles utilized in the test produced lower penetration forces than reverse cutting edge needles. The lower penetration forces encountered by the conventional cutting edge needles imply that the physician should be able to handle these needles with more dexterity and precision than the reverse cutting edge needle.

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.

A fatal case of sun exposure in a multiple sclerosis patient.
A 35-year-old woman with a long standing history of relapsing-remitting multiple sclerosis became physically incapacitated by heat-induced muscle weakness while sunbathing and suffered fatal sun exposure. These deleterious effects of increased core temperature on the neurological symptoms have been documented for a half century. Elevation of the patient's core temperature may lead to either transient or permanent neurologic symptoms and signs that predispose to considerable morbidity and mortality.

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.

Multiple sclerosis and brain tumor: a diagnostic challenge.
Multiple sclerosis may present as a lesion indistinguishable clinically and radiologically from brain tumor. A case of multiple sclerosis is reported with clinical and radiologic features of a brain tumor. A brain biopsy was later undertaken that provided pathological confirmation of the diagnosis of this demyelinating disease. This case report in conjunction with those in the literature indicate that conservative treatment with steroid therapy and serial computed tomography should establish the diagnosis of multiple sclerosis without the need for surgical intervention.

Congenital giant hairy nevus: implications for treatment.
Congenital giant hairy nevi represent a special group of melanocytic lesions which generally cover large areas of the body surface. Giant hairy nevi assume special significance because of their predisposition to malignant transformation. Adequate treatment of this lesion involves complete surgical excision as early in the child's life as possible.

A beveled, conventional cutting edge surgical needle: a new innovation in wound closure.
A new beveled, conventional cutting edge needle has been developed with superior performance characteristics over those of other conventional cutting edge needles. It is composed of a unique stainless steel, ASTM 45500, that has been heat-treated after the curving process to enhance its resistance to bending. The angle of presentation of its cutting edges has been decreased to enhance needle sharpness. On the basis of the results of experimental and clinical investigations, this new needle is recommended for closure of lacerations.
