The arcuate skin staple: its influence on pain of staple penetration and removal.

The purpose of this study was to measure the degree of pain elicited by either staple implantation and by removal in human subjects. Included in the study were conventional rectangular staples and the new arcuate staples. The pain associated with staple implantation was significantly greater than that associated with staple removal. The configuration of the staple did not influence the magnitude of pain associated with either staple implantation or staple removal.

Excision of multiple epidermal facial cysts in Gardner's syndrome.

A rhytidectomy incision is recommended to excise multiple facial epidermal cysts in patients with Gardner's syndrome. The advantage of this approach is that it permits excision of excess skin over the cyst with esthetically pleasing hidden scars. The alternative to this procedure, a separate incision over each cyst, results in disfiguring and conspicuous scars.

Innovations in skin suture removal.

A cutting forceps and suture removal scissors have been specially designed for removal of percutaneous sutures. Our clinical experience with these instruments indicate that they facilitate removal of percutaneous sutures in the surgical patient.

Quality assessment of tetanus prophylaxis in the wounded patient.

New guidelines on tetanus prophylaxis in wound management have been prepared by the American College of Surgeons and are available in a poster format or in bulletins. The purpose of this study was to determine the impact of these educational brochures on tetanus prophylaxis in a hospital setting. The results of this study indicate that these informational brochures and posters had insignificant impact on the quality of prophylaxis against tetanus in our hospital. Innovative programs of information exchange and quality assurance are urgently needed to improve the delivery of health care.

Emergency department management of mammalian bites.

Mammalian bites have reached epidemic proportions with more than one half million people being bitten by an animal or another person. Although the bite wound may initially appear to be innocuous, it may lead to severe complication that can be prevented by a timely and comprehensive treatment program that is outlined in this report. Our approach to these challenging injuries includes a complete evaluation of the injury, planned surgical intervention, antimicrobial therapy, immunoprophylaxis, and appropriate postoperative care.

Clavicular fractures and acromioclavicular joint dislocations in lacrosse: preventable injuries.

Clavicular fractures and acromioclavicular joint dislocations occur frequently in high school lacrosse players. This injury is restricted to attackmen who are struck in the clavicular region by the stick of the defensemen. The conventional foam shoulder pads with or without flexible plastic inserts worn by the attackmen did not protect them from this injury. On the basis of this clinical experience, a new protective shoulder pad containing high-density polyethylene over the clavicle and acromioclavicular joint has been designed and manufactured to prevent these injuries. Our initial experience with this new shoulder pad indicates that it will protect lacrosse players from clavicular fractures and acromioclavicular joint dislocations.

Pseudofolliculitis barbae with keloids.

Pseudofolliculitis barbae is a common cutaneous infection occurring in the bearded area of the face of black men. The infection is caused by ingrown hairs that produce an inflammatory foreign body reaction characterized by papules and pustules at the point of hair penetration that may result in permanent scarring, usually in grooved patterns, and occasionally in keloids. The purpose of this article is to describe the successful treatment of a patient with pseudofolliculitis with keloids that was based on the pathophysiology of the disease and the biology of wound repair.

Epidemiology, pathology, and treatment of axillary hidradenitis suppurativa.

The epidemiology, pathology, and management of axillary hidradenitis suppurativa were examined in 11 patients with this disease. On the basis of this study, the following predisposing factors were incriminated in the epidemiology of the disease: predilection of the disease for women, obesity, hair removal by a safety razor, antiperspirants and deodorants, and local pyogenic infections distant from the axilla. Because antiperspirants do not effect transepidermal water loss of axillary skin, their potential deleterious effects are probably related to their chemical irritant effects on cut, nicked, or irritated axillary skin. Treatment of this disease will vary according to its severity. Incision and drainage are usually needed to treat the localized disease. Specific measures must also be instituted to prevent progression of the disease (eg, weight reduction, avoidance of safety razor and antiperspirants and deodorants, and control of localized pyogenic infections distant from the axilla). Management of the chronic phase of the disease is primarily excision of infected axillary skin.

Toxic epidermal necrolysis.

Toxic epidermal necrolysis (TEN) is a symptom complex characterized by a devastating skin disorder, erosive involvement of two or more mucous membranes, and severe constitutional symptoms. The disorder shares features with erythema multiforme and is thought to be an expression of the syndrome. Although a wide range of etiologic factors have been incriminated in TEN, only a few cases have provided convincing evidence of a direct causal link. Most cases of TEN have been associated with drug administration.

Clinical syndromes caused by staphylococcal epidermolytic toxin.

Coagulase-positive staphylococci of phage group II produce an epidermolytic toxin that results in a spectrum of diseases that include localized bullous impetigo, generalized scarlatiniform syndrome without exfoliation, and staphylococcal scalded-skin syndrome (SSSS). The mechanism of action of the toxin occurs at the level of the lower stratum granulosum, resulting in intraepidermal cleavage. Generalized exfoliative dermatitis, or SSSS, is one of the most severe infections characterized by generalized epidermolysis with desquamation. Generalized scarlatiniform syndrome is an erythematous rash without exfoliation. A localized infection that results in a bulla larger than 5 mm in diameter is bullous impetigo.

Tetanus.

Tetanus is produced by the action of the potent neurotoxin, tetanospasmin, which is elaborated during the growth of Clostridium tetani. The objectives of management of tetanus are to provide supportive care until the tetanospasmin that is fixed in tissue has been metabolized, to neutralize circulating toxin, and to remove the source of tetanospasmin. This disease, which is frequently fatal, is prevented by immunization.

Comparison of morbidity of outpatient general anesthesia administered by the intravenous or inhalation route.

PURPOSE: This study compares the morbidity between subjects receiving general anesthesia either by an intravenous or inhalation route for the extraction of impacted third molars in an outpatient setting. PATIENTS AND MATERIALS: Forty ASA Class I subjects, 21 females and 19 males (age range, 17 to 43 years), who presented for the extraction of four impacted third molars, were studied. Subjects were alternately assigned to receive general anesthesia either by the intravenous route (group I) or the inhalation route via an endotracheal tube (group II). The parameters for comparison included psychomotor recovery, cardiovascular changes 20% above or below baseline, the frequency of nausea and vomiting perioperatively and at 48 hours, occurrence of laryngospasm and bronchospasm, the frequency of sore throat both perioperatively and at 48 hours, procedure time, and recovery time. The Trieger dot test was administered to patients at three different intervals to evaluate psychomotor recovery. All parameters were recorded for each subject and compared both within and between groups. RESULTS: There was no statistical difference found between groups I and II with regard to psychomotor recovery, the frequency of nausea and vomiting, bronchospasm, laryngospasm, or median recovery time (P < .05). However, there was greater variability in both elevation and depression of blood pressure from baseline in the intubated subjects (P < .05). These deviations were both expected and easily managed. The probability of sore throat was greater in the intubated subjects (P < .05) than the nonintubated subjects. Procedure time, although a weak association, was nonetheless found to be significantly greater for the intubated group than for the intravenous group (P < .05). SUMMARY: The results show greater cardiovascular variability, increased probability of sore throat, and slightly lengthened procedure time with the administration of general anesthesia by an inhalational route via an endotracheal intubation. However, there was no difference with regard to psychomotor recovery, recovery time, the probability of nausea and vomiting, or incidence of laryngospasm or bronchospasm.
