Alopecia areata (AA) is a nonscarring form of inflammatory hair loss in humans. AA-like hair loss has also been observed in other species. In recent years the Dundee experimental bald rat and the C3H/HeJ mouse have been put forward as models for human AA. AA in all species presents with a wide range of clinical features from focal, locally extensive, diffuse hair loss, to near universal alopecia. Histologically, all species have dystrophic anagen stage hair follicles associated with a peri- and intrafollicular inflammatory cell infiltrate. Autoantibodies directed against anagen stage hair follicle structures are a consistent finding. Observations on AA pathogenesis suggest nonhuman species can provide excellent models for the human disease. Ultimately, animal models will be used to determine the genetic basis of AA, potential endogenous and/or environmental trigger(s), mechanism(s) of disease initiation and progression, and allow rapid evaluation of new and improved disease treatments.

“…Similar results have been reported in study a conducted by Baran R, Dawber RPR (1994). 10 In our study anaemia was present in 29 patients, psoriasis in 9 patients, palmoplantarkeratoderma in 4 patents and leprosy in 1 patient. The remaining patients had no obvious cause and appeared to be due to ageing process.…”

“…4 Platyonychia and koilonychia were observed in a Potter in our study could be attributed to working with clay.Similar changes have been found by Baran R,1994 in individuals working with clay and wet work. 10 The high prevalence of ragged cuticles and nailfolds with associated paronychia in some cases could be due to occupational exposure. These findings are consistent with the study by Raja babu KK.…”

“…Clubbing was associated with chronic obstructive pulmonary disease, hypertension and malnutrition. Other nail changes seen in our study were smooth / shiny nails (13 patients), brachyonychia (2 patients), longitudinal splitting (1 patient), 4 pterygium unguis secondary to brittle nails / trauma (1 patient), 10 platforming of nail plate or plicated nail (square shaped flattening of nail plate with sharply angled lateral margins) in 1 patient, 10 superficial powdery white patches of nail plate (1 patient), trauma induced onychoptosis (5 patients) 10 and subungual hematoma in 1 patient 3 were presumed to be due to ageing process.…”
