1/3. Avian mite bites acquired from a new source--pet gerbils: report of 2 cases and review of the literature.BACKGROUND: Cutaneous manifestations of avian mite bites are not well recognized by physicians or patients. Clinical signs and symptoms are usually caused by bites from avian mites that have infested domestic poultry or birds nesting in or near human habitation. This report details 2 cases of pruritic papules acquired from avian mites that had infested pet gerbils and reviews the dermatologic literature about avian mites. OBSERVATIONS: An 11-year-old boy and an unrelated 10-year-old girl each had mysterious, pruritic papules for many months before their pet gerbils were found to be infested with Ornithonyssus sylviarum (the northern fowl mite) and Dermanyssus gallinae (the chicken mite), respectively. Symptoms resolved when the gerbils were removed from the home. CONCLUSIONS: Because infestation of pet gerbils with avian mites has never been reported, cases of avian mite bites and dermatitis may have gone unrecognized or misdiagnosed. Inquiry about ownership of pet gerbils may be helpful in patients with mysterious bites.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/3. Ornithonyssus (acari: Macronyssidae) mite dermatitis in poultry field-workers in Almarg, Qalyobiya governorate.Cutaneous manifestations of bird and rat mite infestation in man are not easily recognized by physicians or patients. Clinical signs and symptoms are developed secondary to bites of mites that have infested rats, domestic poultry or birds nesting in or near human habitation and comes into contact with man. This study details 4 cases of pruritic dermatitis developed in four field workers in poultry farms in Al-Marg district, Qalyobia governorate, egypt. The zoonotic species of Ornithoyssus sp., (family Macronyssidae) was isolated from all samples collected from patients' habitat and the role played by Ornithonyssus mites in causing dermatitis in man was discussed.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/3. Nosocomial dermatitis and pruritus caused by pigeon mite infestation.We report an outbreak of pigeon mite infestation involving two patients, two nurses, and one physician on a medical ward in a municipal hospital. The index patient developed a diffuse, pruritic erythematous maculopapular rash on his trunk and extremities. Dermanyssus gallinae, a nonburrowing, blood-sucking avian mite was identified on the patient and his bedding. A second patient who complained of scalp pruritus had mites present on her pillow and bed linen. The intern taking care of both patients, and two nurses who had contact with these patients, had mite infestation. Pigeons roosting on the air conditioners and near the doors connecting the patients' rooms to a sunporch were the source of the mites. The outbreak abated after control measures were instituted that prevented pigeons from roosting on the porch. This outbreak illustrates an unusual cause of nosocomial pruritic dermatitis that may be misdiagnosed as scabies or pediculosis. physicians and health care personnel working in metropolitan areas are alerted to mites as a cause of pruritic dermatitis that may be chronic, recurrent, or unresponsive to ectoparasiticides.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
