1/4. First report of a parasitic mite, Leptotrombidium (Hypotrombidium) subquadratum (Lawerence) (acari: trombiculidae: Trombiculinae), from dogs and children in the Bloemfontein area, south africa.Leptotrombidium subqunadratum larvae were collected for the first time in 1994 from dogs in Bloemfontein. The larvae have been collected annually, during the summer months, over a period of 6-7 years. Previously the only known hosts were scrub hare (Lepus saxatilis) (locality unknown) and short-snouted elephant shrew (Elephantulus brachyrhynchus) (Kruger National Park). These mites cause severe itching and dermatitis in humans and dogs.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
2/4. Successful treatment of two dogs with allergic dermatitis by anti-allergic peptides (MS-antigen).The effects of non-specific immunotherapy with anti-allergic peptides extracted from the urine of human allergic patients (MS-antigen), in two dogs with allergic dermatitis (AD) have been described. Clinically, severe pruritus accompanied by secondary bacterial pyoderma did not respond to conventional therapy with systemic antibiotics. The first clinical change appeared as a significant reduction in pruritus within 3 months, around the time of the 15th injection in both cases. The clinical condition was stabilized after 5 months, allowing the gradual withdrawal of concurrent therapies and an increase of injection intervals. The correlation between the results of intradermal skin tests before and after treatment and the improvement of clinical signs was not obvious.- - - - - - - - - - ranking = 5keywords = dermatitis (Clic here for more details about this article) |
3/4. necrolytic migratory erythema without glucagonoma versus canine superficial necrolytic dermatitis: is hepatic impairment a clue to pathogenesis?The case of a 57-year-old diabetic man with necrolytic migratory erythema in the absence of glucagonoma is reported. The clinical and pathologic features of his dermatitis and subsequent clinical course are compared with those of canine superficial necrolytic dermatitis, an unusual cutaneous necrotizing eruption of dogs that is identical histologically to necrolytic migratory erythema. In addition to a necrolytic dermatitis, both our patient and most dogs with superficial necrolytic dermatitis have diabetes mellitus and hepatic failure in the absence of glucagonoma. Thus hyperglucagonemia most likely is not a factor in the origin of the necrotizing dermatitis in this patient or in dogs. The role of hepatocellular dysfunction in the pathogenesis of necrolytic migratory erythema and superficial necrolytic dermatitis is considered.- - - - - - - - - - ranking = 10keywords = dermatitis (Clic here for more details about this article) |
4/4. Demodex (follicular mite) infesting a boy and his pet dog.Intense iritation and dermatitis, somewhat resembling that produced by scabies can result from various mites living as temporary ectoparasites on the skin of man. Demodex folliculorum is a worm-like mite that infests hair follicles above the level of sebaceous glands in various mammals. In this paper, Demodex folliculorum was recovered from a boy and his pet dog. Both the boy and the dog were successfully treated with permethrin.- - - - - - - - - - ranking = 1keywords = dermatitis (Clic here for more details about this article) |
