comparative study on the efficacy of 0.4% sumethrine and 1% lindane in the treatment of pediculus humanus capitis in Turkey

Two different chemicals were used in the treatment of Pediculus h. capitis in cases which were found to be infested during the screening of 1 secondary and 3 elementary schools in Bostanli- Karsiyaka, Izmir. Sumithrin was found to be more effective than Lindane according to the follow up control performed a month after the treatment. While, the efficacy of Sumithrin in Emlakbank elementary school, Metin Asikoglu elementary school and Emlakbank secondary school was noted as 93%, 96% and 86.8%, respectively. The efficacy of lindane was found to be 67.5% in Murside Akyuz elementary school

Four species of house dust mites recovered from houses of patients with allergic respiratory diseases

In the present study, 4 species of mites were isolated from the dust collected from the houses of patients with allergic respiratory diseases. The species were Dermatophagoides pteronyssinus, D. farinae, Ornithonyssus bacoti and Hemogamasus pontiger. The 2 species of Dermatophagoides were the predominant mites, which are known to produce the most potent allergens. Studying the serum immunoglobulins level showed that the IgE had a highly significant concentration among respiratory allergic patients [28] with [5] or without [23] atopic dermatitis. It was concluded that house dust mites, that cause inhalant allergens, are one of the main etiological factors of allergic respiratory diseases, with or without atopic dermatitis

Mites [acari] infesting commensal rats in Suez canal zone, Egypt

Mites are arthropods distinguished from ticks by usually being microscopical in size and have a hypostome unarmed with tooth- like anchoring processes. They are group in a number of suborders, each with super-families and families including many genera of medical and economic importance. In this paper, commensal rodents [Rattus norvegicus, R. r. alexandrinus and R. r. frugivorous] were surveyed in the Suez Canal Zone for their acari ectoparasites. 4 species of mites were recovered. In descending order of mite indices, they were Eulaelaps stabularis [4.83 on 6 rats], Laelaps nuttalli [3.11 on 27 rats], Ornithonyssus bacoti [1.66 on 9 rats] and Dermanyssus gallinae [0.66 on 24 rats]. The overall mite indices in the 3 governorates were 3.66 in Suez, 2.82 in Ismailia and zero in Port Said. The medical and economic importance of the mites were discussed

Phthiriasis palpebrarum in Pakistan

A 14-year-old girl from Sindh Pakistan had phthiriasis paplpebraum, infestation with Phthirus pubis, of her right upper eyelid. This case in a Pakistani patient is most unusual in that the Muslim cleanliness practices include regular shaving of the pubic and axillary hair and the sociosexual mores do not permit sexual promiscuity, eliminating the two likely sources of phthiriasis. Pediculosis capitis and pediculosis coporis on the other hand are common due to widespread poverty in rural areas of Pakistan. [Pakistan Journal of Ophthalmology 9: 6, 20, January, 1993]
