  ::   Introduction Top

A house to house morbidity survey in Malavani in December 1977 revealed that the prevalence of scabies was 47 per 1000 population.[1] Experience in the out patient department of dermatology of the K.E.M. Hospital, run by the Municipal Corporation of Greater Bombay, has shown that the results of unsuperivised home treatment of scabies are unsatisfactory. The present paper describes the results of a novel method of supervised treatment of scabies, in the entire family units, developed at the Malavani Health Centre.

  ::   Material and methods Top

The patients in this study (Group I) were those attending the Malavani Health Centre for treatment of scabies. The organization of the centre has already been described in an earlier paper.[1] The results of the new immersion (dip) method were compared with those of the conventional method of treatment in a group of patients (Group II) attending the dermatology outpatient department of the K.E.M. Hospital. The results of the treatments were evaluated at both places by the same team.
In every case in Group I, all members of a family were treated at one time. Each member of the family, including the index case, was examined by a doctor and the skin lesions were recorded on a chart. The patient was then made to take a bath with soap and water at the centre, and finally made to squat completely naked in 10% aqueous benzyl benzoate emulsion contained in an R.C.C. or a syntex tank. The tank measured 1 m x 1 m x 1 m and contained about 30 litres of 10% aqueous benzyl benzoate emulsion. Care was taken to see that the hips and the perineal area were immersed in the emulsion. The R.C.C. tank was fixed in the Health Centre whereas the syntex tanks were movable. While squatting in the tank, the patient scrubbed areas of skin lesions with a gauze piece to break open the lesions. The patient also smeared the emulsion all over the body. He/she then stood outside the tank to allow the body to dry. He/she then wore his/her clothes and was instructed not to remove them for the next 24 hours. The entire operation was supervised by the clinic staff, a male in the case of male patients and a female in the case of female patients. The same emulsion was used over and over again; about 100 litres were required for 500 patients. No other treatment such as an antipruritic agent or an antibiotic was used in these patients.
In Group II, the patient was advised to bring all the family members to the hospital for treatment. Each infected person was given 300 ml of a 25% aqueous benzyl benzoate emulsion for three applications at home. Those with a bacterial infection were given an antibiotic in addition.
The patient was labelled as cured if all the skin lesions disappeared at the end of a week, as partially cured if 50% or more lesions disappeared; and as a failure if fewer than 50% lesions disappeared. A second treatment was given to failures as well as to those whose itching persisted beyond 7 days after the first treatment.

  ::   Results Top

[Table - 1] shows the cure rate with both the immersion and conventional methods. The superiority of the immersion method is obvious.
[Table - 2] shows the rate of disappearance of itching with the two methods of treatment. Nine hundred and three 21.2%) of Group I patients and 748 (51.77%) of Group II patients required a second course of treatment; they included the `failures' shown in [Table - 1]
[Table - 3] shows the effectiveness of the second course of dip treatment when required.
The dip in aqueous benzyl benzoate emulsion was well tolerated by children and by adults and the only adverse effect occasionally recorded was chemical conjunctivitis which was self-limiting.
[Table - 4] shows the approximate cost of treatment of 500, patients at the prices prevailing in 1983. The conventional treatment was found to be roughly 8 times as costly as the dip treatment.

  ::   Discussion Top

The advantages of the supervised treatment have been well described in the case of tuberculosis.[3] Supervised treatment of scabies is being described for the first time to the best of our knowledge. Its effectiveness and low cost are well demonstrated by this study. The dip method is safe and can be supervised by paramedical or even non-medical personnel. Using portable syntex tubs, it can be applied even in the remotest parts of the countryside. Thus, the dip method of treating scabies is likely to prove to be the answer to the problem of scabies in the developing countries like India.
