Community control of scabies: a model based on use of permethrin cream.

For 18 years treatment with lindane or crotamiton products has failed to stem the epidemic of scabies among the Kuna Indians in the San Blas islands of the Republic of Panama. Permethrin 5% cream was introduced as the only treatment in a programme to control scabies on an island of 756 inhabitants and involving workers recruited locally. Prevalence fell from 33% to less than 1% after every person was treated. As long as continued surveillance and treatment of newly introduced cases was maintained, prevalence of scabies remained below 1.5% for over 3 years. When supply of medication was interrupted for 3 weeks, prevalence rose to 3.6%. When control was lost after the US invasion of Panama, prevalence rose to 12% within 3 months. Bacterial skin infections decreased dramatically when scabies was controlled. Permethrin is safe and effective even in areas where this disease has become resistant to lindane.

Comparison of crotamiton 10% cream (Eurax) and permethrin 5% cream (Elimite) for the treatment of scabies in children.

Permethrin 5% cream (Elimite) was approved as a treatment for scabies by the U.S. Food and Drug Administration in September 1989. In a double-blinded, randomized study, it was compared with crotamiton 10% cream (Eurax) for the treatment of scabies in children 2 months to 5 years of age. Two weeks after a single overnight treatment, 14 (30%) of 47 children were cured with permethrin 5% cream, in contrast to only 6 of 47 (13%) of subjects treated with Eurax. Four weeks after treatment the figures were 89% and 60% cured for the two agents, respectively. In 10 of the 19 patients whose treatment failed, the condition became worse after therapy. The difference in efficacy in favor of permethrin was significant (P = 0.002). That agent also demonstrated greater effectiveness in reducing pruritus and secondary bacterial infections. Elimite offers a safe, efficacious, and cosmetically elegant alternative to Eurax in the treatment of scabies in children.

Scabies, lice, and fungal infections.

Scabies and pediculosis capitis are frequent and often unrecognized causes of multiple streptococcal and staphylococcal pyodermas. Permethrin 1 per cent creme rinse (NIX) for head lice, and permethrin 5 per cent topical cream for scabies are new, highly effective, safe, and cosmetically elegant treatments which have shown superiority over older remedies. In populations in which pediculosis and scabies have resisted traditional lindane therapy, patients promptly responded to these permethrin products. Scabies in nursing homes is a persistent and expanding problem which demands a high level of diagnostic suspicion and an integrated approach to management. For fungal infections, several new broad-spectrum oral and topical agents have been introduced. Their successful use is enhanced by appropriate diagnostic tests which can be performed in the office setting. Recommendations and references are given to assist the physician in diagnosis and choice of therapy.

Sulconazole nitrate cream 1 percent for treating tinea cruris and corporis.

Sulconazole nitrate 1 percent cream, a new imidazole derivative, was tested in 117 Colombian Army soldiers with tinea cruris/corporis under hot, humid conditions. The results of two clinical trials demonstrate that sulconazole applied once daily was as effective as clotrimazole applied twice daily. After three weeks of therapy 100 percent of the patients treated either once or twice daily with sulconazole showed negative findings on potassium hydroxide preparations and cultures from lesions. Although sulconazole was well tolerated and caused no adverse reactions, four of twenty-seven clotrimazole-treated patients showed reactions consisting of erosive primary irritation. Sulconazole nitrate 1 percent cream appears to be highly effective in the treatment of tinea cruris/corporis when applied once or twice daily and may be very useful in hot and humid conditions where contact irritation reactions occur more often.

Permethrin 5% dermal cream: a new treatment for scabies.

Permethrin 5% dermal cream (Burroughs Wellcome Co.) was compared in an investigator-blinded, randomized study against lindane 1% lotion (Kwell) for the treatment of microscopically confirmed scabies. Eleven of twenty-three patients treated with permethrin cream were cured in 2 weeks (48%). Only two patients had scabies 1 month following a single treatment with this product, giving a cure rate of 91%. One of these two patients was considered to have a reinfestation. Only three of twenty-three (13%) patients treated with 1% lindane lotion (Kwell) were free of scabies 2 weeks after a single treatment and fifteen of twenty-three (65%) were cured at 1 month. The unusually high percentage of treatment failures (35%) following lindane therapy may have been related to extensive use of this agent for head lice and scabies in this village during the preceding 5 years. The higher cure rate at 1 month seen with permethrin cream was significant (p less than 0.025). Permethrin 5% dermal cream offers a new, cosmetically elegant alternative to lindane therapy and was effective in a community in which lindane demonstrated an unacceptable level of treatment failures.

Permethrin 1% creme rinse for the treatment of Pediculus humanus var capitis infestation.

Permethrin 1% creme rinse (NIX) was tested as a treatment for Pediculus humanus var capitis (head lice) in a placebo-controlled, double-blinded, randomized study. As a positive control, a third arm of the study included nonrandomized, but investigator-blinded, treatment with 1% lindane shampoo (Kwell). At 14 days after treatment, 97% of patients treated with permethrin were free of lice compared to 6% of placebo-treated patients (P less than 0.001) and 43% of the lindane-treated group. Permethrin was 70% ovicidal compared to 14% for placebo (P less than 0.001) and 45% for lindane. No adverse experiences were noted during this study. Permethrin 1% demonstrated high pediculicidal and ovicidal activities, which in combination with its low mammalian toxicity, residual activity, and cosmetic properties, make it an excellent treatment for pediculosis capitis.

Comparative efficacy of treatments for pediculosis capitis infestations.

Ovicidal activity and killing times were evaluated for six pediculicides, using viable eggs and recently fed head lice from infested children. Lice were continuously exposed to the products until death, and elapsed time was recorded. Eggs were immersed for ten minutes, rinsed, and dried. Four synergized pyrethrin products (RID, R&C Shampoo, A-200 Pyrinate Shampoo, A-200 Pyrinate Liquid) killed all lice in ten to 23 minutes, and 23% to 32% of treated eggs hatched; 0.5% malathion lotion (Prioderm Lotion) killed lice within five minutes and was highly ovicidal, with only 5% of eggs hatching. One percent lindane shampoo (Kwell Shampoo) was the slowest-acting pediculicide, requiring approximately three hours to kill all lice; 30% of the eggs hatched after treatment. The in vitro results for RID, Prioderm Lotion, and K well Shampoo were validated by clinical trials.

Eradication of scabies with a single treatment schedule.

A single application (16 to 20 hours) of 1% gamma benzene hexachloride (GBH) lotion, when applied to a total island population of 178 persons in which seventy-four clinically had scabies, resulted in a cure rate of over 98%. Re-examination of the population at 10 and 21 weeks revealed only one remaining individual still having scabies. On a neighboring island, only those with clinical evidence of scabies were treated (140 persons). Applications of 1% GBH lotion were applied with the same methods used on the first island. When the population was re-examined at 10 weeks, the prevalence of scabies was reduced by only 50%. Successful eradication of scabies from a population should include treatment of all contacts, whether clinically infected or not. Treatment of the entire population at risk at one time is preferable. Coexistent pyoderma should be treated, and a second treatment for scabies may be needed when the pyoderma has cleared.

A comparative trial of three treatment schedules for the eradication of scabies.

A trial of three treatment schedules, consisting of 1% gamma benzene hexachloride (GBH) lotion applied head to toe and left on the body for 2, 6, or 12 to 24 hours was conducted on an island of 2,076 persons, approximately 70% of whom had clinical evidence of scabies. The island is situated off the north coast of the Republic of Panama. Examination at 1 month after therapy showed that both the 6-hour and 12- to 24-hour cure rate was high (96% and 98%). There was a significantly lower cure rate in the 2-hour group, in which only 82% were cured. Eleven to twelve percent of the subjects became infested in all groups, presumably due to contact with untreated persons with scabies on the island. A single 6-hour application of 1% GBH lotion appears to be adequate therapy for scabies if properly applied. The entire population at risk should be treated at the same time if possible to reduce or eliminate the risk of infestation. No adverse reactions to 1% GBH lotion were observed.

Fatal Aeromonas hydrophila infection of the skin.

A 62-year-old woman developed a fatal Aeromonas hydrophila infection of the skin after dropping a crab trap on her leg. The area surrounding the punctures was erythematous and had several flaccid bullae. A biopsy specimen of the involved skin showed necrosis and suppuration in the dermis and subcutaneous fat. The A hydrophila sepsis resolved after treatment with gentamicin, but the patient developed secondary wound infections and died three months after injury.

A community outbreak of scabies.

An elementary school in Broward County, Florida, reported an outbreak of scabies in January and February 1975. Investigation identified 23 cases of scabies in schoolchildren, with at least two cases in each grade. The first case had appeared as early as July 1974, but most occurred after December. There was little contact between students in different grades; most transmission was found to have taken place within families and in the community. An additional 28 cases were found in families and contacts; altogether, 51 cases in 24 families were identified on clinical or historical grounds. Infestation was more frequent in children who exchanged clothes with friends or relatives and in those who, on occasion, spent the night with other children.

Superficial mycoses.

Twenty-five years ago many of the topical remedies for superficial mycoses were irritating, toxic, or allergenic. Total x-ray depilation of the scalp was the accepted mode of therapy for tinea capitis. The introduction of topical nystatin for candidiasis and tolnaftate for dermatophytosis were major advances, but tinea capitis, onychomycosis, and chronic tinea pedis still presented problems. Soon after its introduction in 1958, griseofulvin became the definitive form of therapy for all types of dermatophytosis and played a major role in abolishing large-scale epidemics of tinea capitis in some countries. Recently, haloprogin and the imidazole derivatives, miconazole and clotrimazole, which are topically active against dermatophytes and Candida albicans, have become available. Selective indicator media for isolating dermatophytes are useful diagnostic tools, but quicker methods of diagnosis which require little interpretation are still lacking. Epidemiologic studies in Vietnam again revealed the effects of climate and occlusion on the prevalence, incidence, and severity of superficial mycoses and led to renewed interest in host susceptibility, environment, and prevention of infections.
