Prospective evaluation of topical antibiotics for preventing infections in uncomplicated soft-tissue wounds repaired in the ED.

OBJECTIVE: To determine differences in infection rates among uncomplicated, repaired wounds managed with: topical bacitracin zinc (BAC); neomycin sulfate, bacitracin zinc, and polymyxin B sulfate combination (NEO); silver sulfadiazine (SIL); and petrolatum (PTR). METHODS: This was a prospective, randomized, double-blind, placebo-controlled study conducted at a military community hospital with an emergency medicine residency program. Patients were enrolled if they: presented to the ED within 12 hours of injury and did not have puncture wounds, allergies to the agents used, or a history of immunocompromise; were not receiving antibiotics, chemotherapy, or steroids at the time of presentation; had not taken antibiotics within the preceding seven days; did not have an underlying fracture; and were not pregnant as determined by history. Local anesthetics without epinephrine and high-pressure irrigation with normal saline were used for all patients. Wound scrubbing, débridement, and polyglactin subcutaneous (SQ) suture placement were carried out when necessary. Interrupted simple sutures using a monofilament, nonabsorbable material were used for skin closure. Numbered, randomized vials were given to all patients, with standardized instructions to inspect, clean, and redress their wounds three times a day. The wounds were evaluated for clinical infection at the time of follow-up. RESULTS: Among the groups, there was no difference in patient ages; gender; wound location, type, length, or depth; time elapsed from injury to ED treatment; number of wounds scrubbed or necessitating débridement; number of SQ and cutaneous sutures used; and rate of compliance with returning the used vial of dispensed topical agent. The wound infection rates for the treatment groups were: BAC, six of 109 (5.5%); NEO, five of 110 (4.5%); SIL, 12 of 99 (12.1%); and PTR, 19 of 108 (17.6%) (p = 0.0034). CONCLUSION: The use of topical antibiotics resulted in significantly lower infection rates than did the use of a petrolatum control. BAC and NEO had the lowest wound infection rates.

Alkaline chemical burn to the face requiring full-thickness skin grafting.

A case of a patient with an alkaline chemical burn to the face from the misuse of the aerosol form of an oven cleaner is presented. The low concentration of sodium hydroxide and lack of early pain delayed the patient's presentation to the emergency department for two hours. After this delay in seeking treatment, continuous irrigation in the ED did little to modify the pH of the patient's injured skin. Thus, she developed a full-thickness alkaline burn that eventually required skin grafting.

[Collodion baby: 32 new case reports]. / Bébé collodion. Trente-deux nouvelles observations.

A critical study of 69 cases of collodion baby observed between 1976 and 1984 is compared with the study conducted in 1976. These 69 cases are divided into 32 examined by the authors personally and 37 published in the literature. The total number of collodion babies is 267. A collodion baby is a high risk newborn who must be nursed in a specialized intensive care unit during the neonatal period. The vital prognosis has been improved by the prevention of metabolic disorders (dehydration with hypernatraemia) and of percutaneous intoxication with topical products, and by the early treatment of infections. The mortality rate, which was 33 p. 100 in 1976, had fallen to 11 p. 100 in 1984. Skin infection with systemic spread remains the major complication (the present situation is summarized in table II). The collodion baby is the neonatal expression of different disorders of keratinization and as such, constitutes a syndrome. Several conclusions can be drawn from a comparison of the keratinization disorders observed in our two series (table VI). Congenital ichthyosiform erythroderma and lamellar ichthyosis are responsible for 60 p. 100 of collodion babies. These two lesions may be the first signs of an ichthyosis transmitted as an autosomal dominant trait in 9.7 p. 100 of the cases. Trichothiodystrophy may be heralded by a collodion baby syndrome. In 9.7 p. 100 of the cases this syndrome disappears without sequelae. Sex-linked ichthyosis never begins with a collodion baby syndrome.
