1/27. herpes zoster in seven disparate dermatomes (zoster multiplex): report of a case and review of the literature.Noncontiguous multidermatomal herpes zoster is very rare in both immunocompetent and immunocompromised persons. Most of the reported cases have been limited to 2 noncontiguous dermatomes. This unique presentation has been referred to as zoster duplex unilateralis or bilateralis, depending on whether one or both halves of the body are involved. Granulomatous dermatitis at sites of herpes zoster scars, a rare isotopic response, has only been reported in persons with contiguous dermatomes of zoster. We describe an immunocompromised patient who developed herpes zoster in 7 disparate dermatomes. Three months after resolution of the zoster, the patient developed a granulomatous dermatitis in a zosteriform distribution at the sites of previous infection.- - - - - - - - - - ranking = 1keywords = mite (Clic here for more details about this article) |

3/27. 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 = 12.022650150432keywords = mite, infestation (Clic here for more details about this article) |

5/27. dermatitis in humans associated with the mites Pyemotes tritici, Dermanyssus gallinae, Ornithonyssus bacoti and Androlaelaps casalis in israel.Multiple erythematous papules accompanied by severe pruritus were observed in humans bitten by the mites (acari) Pyemotes tritici (Newport) (Pyemotidae), Dermanyssus gallinae (De Geer) (Dermanyssidae), Ornithonyssus bacoti Hirst (Macronyssidae) and Androlaelaps casalis (Berlese) (Laelapidae). Eight case histories are presented and the impact of these species on human health is discussed.- - - - - - - - - - ranking = 5keywords = mite (Clic here for more details about this article) |
6/27. arthritis and interstitial granulomatous dermatitis (Ackerman syndrome) with pulmonary silicosis.OBJECTIVE: To describe the case of a patient suffering from pulmonary silicosis associated with a rheumatoid factor negative, antinuclear antibody positive, symmetrical, nonerosive synovitis, and interstitial granulomatous dermatitis (IGD) and compare it with similar cases reported in the literature. methods: literature search to identify published cases of IGD with arthritis and cases associated with silicosis. RESULTS: Thiry-eight cases of IGD with arthritis were found. These cases were associated with various conditions such as drug reactions, autoimmune diseases, chronic infections, or paraneoplastic syndromes for which no specific underlying cause was identified. The patient had skin lesions corresponding to the rope sign, as noted in other reports. histology showed a histiocytic, granulomatous dermatitis, which, in association with arthritis, was first described by Ackerman et al. Circulating immune complexes or altered apoptosis have been discussed as mechanisms, although there is no experimental evidence to support either hypothesis. As in other cases, treatment had limited success. Most relief was achieved with hydroxychloroquine, dapsone, and corticosteroids. CONCLUSIONS: arthritis and IGD associated with silicosis is a rare clinical entity that can be differentiated from other conditions. This condition should be considered when patients present with typical dermatologic features, such as the rope sign, and arthritis.- - - - - - - - - - ranking = 1keywords = mite (Clic here for more details about this article) |
7/27. Pet hamsters as a source of rat mite dermatitis.Rat mite dermatitis is characterized by pruritic papules in a patient exposed to the tropical rat mite Ornithonyssus bacoti. We report a case of a woman with rat mite dermatitis who developed this eruption after exposure to her pet hamster. mites were collected from the hamster and identified as O bacoti. Reported sources of rat mites, as well as avian mites and other mites that bite humans, are reviewed.- - - - - - - - - - ranking = 10keywords = mite (Clic here for more details about this article) |
8/27. adult T-cell leukaemia/lymphoma-like human T-cell leukaemia virus-1 replication in infective dermatitis.adult T-cell leukaemia/lymphoma (ATLL) is a malignant T-cell proliferation that occurs in 3-5% of individuals infected with human T-cell leukaemia virus-1 (HTLV-1). HTLV-1 infection is also linked to the development of infective dermatitis (ID), an exudative dermatitis of children that has been proposed as a cofactor of ATLL. Here, HTLV-1 replication was investigated over time in a girl with ID and multiparasitic infestation including strongyloidiasis, a disease also known to predispose HTLV-1 carriers to ATLL. Quantitative polymerase chain reaction (PCR) revealed extremely high proviral loads. During the 2-year period of the present study, the proportion of circulating infected cells ranged between 12% and 36%. Quadruplicate linker-mediated PCR amplification of HTLV-1 flanking sequences identified a pattern of extensive and persistent oligoclonal expansion of infected lymphocytes. As viral loads, both the number and the degree of infected T-cell expansion were independent of treatment or clinical signs. However, the temporal fluctuation of proviral loads correlated significantly with the degree of infected T-cell expansion, but not with the overall number of detected clones. This pattern of HTLV-1 replication over time is very different from that observed in asymptomatic carriers and reminiscent of that observed in ATLL, a result consistent with the proposal of ID as an ATLL cofactor.- - - - - - - - - - ranking = 0.022650150431879keywords = infestation (Clic here for more details about this article) |
9/27. Estrogen dermatitis that appeared twice in each menstrual period.A 23-year-old woman presented with millet-sized red papules that were scattered over her chest and abdomen. She stated that since the age of 20, she had recurrently suffered from pruritic eruptions that coincided with ovulation and the time prior to menstruation, and that they persisted for a few days before vanishing spontaneously leaving some pigmentation. A skin biopsy specimen revealed spongiotic bullae in the epidermis and marked infiltration of lymphocytes accompanied by some histiocytes and eosinophils in the upper dermis. An intradermal test for conjugated estrogen showed an urticarial reaction that faded in about four hours. Although the test did not strictly meet the criterion (erythema to remain for more than 24 hours for papulovesicular eruptions), it was concluded that the timing of the episodes along with the result of the test suggested that a diagnosis of estrogen dermatitis was highly probable. There have been several reports of this condition since it was first reported as a distinct entity in 1995; but whatever the reasons, the flares were observed only before menstruation in these cases, despite the fact that the serum estrogen levels showed a double-peaked pattern during each menstrual period. This is considered to be a rare case of estrogen dermatitis that flared twice in each menstrual period. Limited improvement was noted in the symptoms even without treatment.- - - - - - - - - - ranking = 1keywords = mite (Clic here for more details about this article) |
10/27. Seronegative systemic lupus erythematosus.We have presented a patient with severe clinical SLE but negative serological tests. This diagnostic difficulty, together with a presentation limited to the skin and an initial response to high dose steroids probably lead to a delay in starting immunosuppression. The finding of a retinopathy was important in deciding on therapy. An excellent response to immunosuppression was seen, with full recovery.- - - - - - - - - - ranking = 1keywords = mite (Clic here for more details about this article) |
