Prophylactic antibiotics in aesthetic and reconstructive surgery.

The widespread use of antibacterial agents for prophylaxis has altered surgical practice markedly in the past 20 years and now represents one of the most frequent uses of antibiotics in hospitals, accounting for as many as half of all antibiotics prescribed. The present study was undertaken to determine the patterns of and reasons for antibacterial agent usage by today's practicing plastic surgeons in Israel. A survey of 78 Israeli plastic surgeons certified by the Israeli Association of Plastic Surgery was conducted. Questionnaires were mailed to all the certified plastic surgeons; 66 (84.6%) were completed and returned. The results indicate that prophylactic antibiotics are administered in a high percentage of aesthetic and reconstructive surgeries except for those in eyelids and nose. Most of the surgeons prefer to prescribe cephalosporins as their antibiotics of choice and the timing of administration is before or at the beginning of surgery. Placement of drains did not change the decision to use prophylaxis. Diabetes mellitus, steroid treatment, and chronic lung disease have a direct influence on the decision to use antibiotics; however, conditions such as ischemic heart disease, hypertension, and cigarette smoking do not influence their use. Personal experience was the main reason for prescribing antimicrobial agents. We conclude that although the infection rate in aesthetic and reconstructive operations is extremely low, most Israeli plastic surgeons still prefer to administer prophylactic antibiotics though no scientific hard data is available.

Prolonged elimination half-life of phenol after dermal exposure.

BACKGROUND: Phenol is a general protoplastic poison which has been in use in medicine and industry for decades. It is readily absorbed through the skin causing both local and systemic toxicity. CASE REPORT: A 47-year-old male had 90% phenol spilled over his left foot and shoe (3% of body surface area). After a 4 1/2-hour exposure, manifestations included confusion, vertigo, faintness, hypotension, ventricular premature beats, atrial fibrillation, dark-green urine, and tense swelling, blue-black discoloration, hypalgesia, and hypoesthesia of the affected area. Treatment consisted of irrigation with copious amounts of water, incisions, and supportive measures. RESULTS: Peak serum phenol was 21.6 micrograms/mL, considered in the fatal range. Peak urine phenol plus urine-conjugated phenol was 13,416 mg/g creatinine, indicating a major absorption. Elimination half-life was 13.86 hours, considerably longer than previously reported. CONCLUSIONS: Prolonged skin contact with concentrated phenol in an occlusive environment may result in a major absorption and a long elimination half-life even if the area involved is small. Prolonged elimination may be explained by extensive tissue distribution or by "slow-release reservoir" properties of the skin. Such exposure may be associated with severe systemic and local toxicities. Immediate removal from exposure and aggressive decontamination of the skin are essential to reduce these risks.

Cystic kidney dysplasia and polydactyly in 3 sibs with Bardet-Biedl syndrome.

Two infants with cystic kidney dysplasia and polydactyly were born to consanguineous parents. One infant died at age 2 months, and the other is currently 3.5 years old. A third pregnancy was terminated following ultrasonographic visualization of large echo-dense fetal kidneys and polydactyly. Although none had apparent brain anomalies, they were considered to represent the Meckel syndrome. Extinguished responses on electroretinography in our 3.5-year-old patient has led to the diagnosis of Bardet-Biedl syndrome. This observation offers an opportunity to revisit the Bardet-Biedl syndrome and provides further evidence that structural renal abnormalities are characteristic of the syndrome. We wish to alert the clinician to the diagnosis of Bardet-Biedl syndrome in patients with infantile cystic kidney dysplasia.

Dextrocardia, microphthalmia, cleft palate, choreoathetosis, and mental retardation in an infant born to consanguineous parents.

We report on an infant (born to consanguineous parents) with an unusual face, microphthalmia, cleft palate, dextrocardia, choreoathetosis, and mental retardation. This child has many traits in common with an infant recently described by Aughton [1990] as a probable new syndrome.

Apert's syndrome with occipital encephalocele and absence of corpus callosum.

A case of Apert's syndrome with posterior (occipital) encephalocele and absence of corpus callosum is described. This is a rare combination. The mechanisms involved are discussed.
