1/8. Epidemic Norwegian scabies.Norwegian scabies is an ectoparasitic infestation by sarcoptes scabiei, characterized by hyperkeratotic lesions of the hands, feet, ears, and scalp, which contain many mites. An epidemic of Norwegian scabies involved 22 patients in a 25-patient ward of mentally and physically handicapped persons (mostly mongoloids). The pathogenesis of the prolific mite population is unclear, but either a specific immunologic deficit or the inability to effectively eliminate the mites by scratching is a plausible possibility.- - - - - - - - - - ranking = 1keywords = scabies (Clic here for more details about this article) |
2/8. dermoscopy for the in vivo detection of sarcoptes scabiei.We report the case of an 80-year-old patient who had intense pruritus which did not respond to a 3-month treatment with topical corticosteroids. On dermoscopy examination of the excoriations, we found the typical dermoscopic aspect of the scabies mite at a distance. dermoscopy allows identifying a triangular structure which corresponds to the anterior section of the mite including the mouth part and the 2 pairs of front legs. This aspect has been described as resembling a jetliner with its trail, a delta glider or a spermatozoid. Traditional diagnostic methods for scabies failed in this case because the mites were at a distance from the burrows. This was due to the fact that the reaction to the mite was less pronounced and the diagnosis is frequently missed. dermoscopy is a useful tool for the diagnosis of scabies either as a diagnostic test or to guide the traditional diagnostic tests.- - - - - - - - - - ranking = 0.5keywords = scabies (Clic here for more details about this article) |
3/8. Reactive perforating collagenosis associated with scabies in a diabetic.Reactive perforating collagenosis (RPC) in adults commonly manifests in patients with diabetes mellitus. pruritus and consequent induced scratching have been identified as the bases for the evolution of this skin disease. We present the unusual case of a 55-year-old female diabetic with characteristic umbilicated skin lesions and a long history of scabies. histology from a crusty nodule revealed transepidermal elimination of collagen. Following antiscabietic treatment, two courses of oral doxycycline demonstrated beneficial effects in controlling the perforating skin disorder.- - - - - - - - - - ranking = 0.83333333333333keywords = scabies (Clic here for more details about this article) |
4/8. A dilemma: bullous-pemphigoid-like eruption in scabies or scabies-induced bullous pemphigoid.Several diseases may be confused with scabies. Atypical manifestations of scabies have previously been reported, including urticaria, contact dermatitis, and dermatitis herpetiformis. There are also reports of scabies mimicking bullous pemphigoid. Here we report a case of scabies in a patient with manifestation similar to bullous pemphigoid. Direct smear of the bullous lesions was performed and was positive for scabies mites. The skin biopsy specimens submitted for light microscopy and direct immunofluorescence study were considered to be compatible with bullous pemphigoid. The patient treated with single dose oral ivermectin and prednisolone. The pruritus subsided and the eruption improved dramatically in 2 weeks.- - - - - - - - - - ranking = 2.1666666666667keywords = scabies (Clic here for more details about this article) |
5/8. Pseudouremic pruritus: a scabies epidemic in a dialysis unit.A scabies epidemic was studied in a university hospital dialysis unit. Itching in patients was initially attributed to uremic pruritus, and diagnosis of the epidemic was delayed until cases occurred among the staff. Sixteen cases (seven patients and nine staff) were identified by survey questionnaire and dermatologic examination. Application of 1% lindane lotion (Kwell, Reed and Carnrick, Piscataway, NJ) to all patients dialyzed in the unit and the entire staff eradicated the epidemic. A dialysis unit-associated nosocomial scabies epidemic has not been reported before and may mimic uremic pruritus in dialysis patients.- - - - - - - - - - ranking = 1keywords = scabies (Clic here for more details about this article) |
6/8. 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 = 0.16666666666667keywords = scabies (Clic here for more details about this article) |
7/8. Crusted (Norwegian) scabies in patients with AIDS: the range of clinical presentations.Crusted (Norwegian) scabies in AIDS patients can be manifested in both typical and atypical forms. Although the classic, hyperkeratotic, nonpruritic lesions are most common, reported cases have ranged in spectrum from crusting with pruritus to a pruritic, papular dermatitis to those resembling Darier's disease or psoriasis. We report two additional cases of crusted scabies in AIDS patients, one with typical crusted, hyperkeratotic though pruritic lesions and one with severe pruritis and rare papules, initially misdiagnosed as "pruritus of AIDS." Because of the extremely contagious nature of crusted scabies, as well as its potential for complete cure with appropriate therapy, a high degree of suspicion for this disorder should be maintained in AIDS patients, even when the lesions do not have the classical appearance. The discovery of crusted scabies, whether in its common or its atypical form should prompt testing for the human immunodeficiency virus (hiv).- - - - - - - - - - ranking = 1.3333333333333keywords = scabies (Clic here for more details about this article) |
8/8. scabies: case presentation.scabies is a skin infestation of a mite which is spread by skin-to-skin contact and causes an intense generalized intractable pruritus. This case presentation demonstrates how scabies can be mistaken for other skin conditions, and the importance of proper diagnosis, treatment, and followup.- - - - - - - - - - ranking = 0.16666666666667keywords = scabies (Clic here for more details about this article) |
