Onychomycosis among psoriasis patients is reported with varying prevalence. This prospective, controlled study investigates the occurrence of onychomycosis among inpatients with psoriasis versus inpatients with other skin diseases. The inclusion period was 15 months. Scrapings from clinically abnormal nails (both fingernails and toenails) were examined using microscopy and culture. The prevalen...

BACKGROUND Toenails were assessed as an alternative matrix to hair for retrospective monitoring of cocaine consumption of recreational and dependent users. Results/methodology: Toenail clippings, scrapings and hair samples from recreational and dependent cocaine users were analyzed for cocaine and metabolites. Dependent users displayed significantly higher concentrations in hair and toenail sam...

BACKGROUND Pincer nail deformity is a transverse overcurvature of the nail. This study aimed to define the anatomical characteristics of pincer nail deformity and to evaluate the surgical outcomes. METHODS A retrospective review was conducted on 20 cases of pincer nail deformity of the great toe. Thirty subjects without pincer nail deformity or history of trauma of the feet were selected as t...

Various techniques for nail reconstruction have been reported until now; however, a simple one providing good esthetic results was difficult to find. Arterialized venous toenail flap is a free flap that includes the nail bed and matrix with a pedicle formed solely by the subcutaneous vein of the toe. The use of this flap is minimally invasive and easy, and the flap has a high survival rate. The...

Six techniques not yet widely known or used in the dermatologic surgery of the nails are briefly described. Small-to-medium-sized tumours of the proximal nail fold (PNF) can be excised and the defect repaired with advancement or rotation flaps. A superficial biopsy technique of the matrix for the diagnosis of longitudinal brown streaks in the nail, which allows rapid histological diagnosis of t...

The numerous methods used for treating ingrowing toe-nails are testimony to the lack of a generally acceptable procedure with a low failure rate. A simple procedure with nail preservation is described, and the results of treatment assessed. The procedure consists of making a transposition flap of the nail wall after preliminary curettage of the granulation tissue in the nail groove. A total of ...

Fig. 2. Strong HMB-45 positivity of the tumour cells (×200). Sir, Subungual melanoma is a relatively rare disease with a reported incidence of between 0.7% to 3.5% of all melanoma cases in the general population (1). Most common sites of involvement are the big toe, the thumb and the index and ring fingers, respectively (2–4). Common signs include pigmentation of the nail bed, nail loss, and na...

Zadik’s operation and segmental ablation of the nail bed are common treatments for ingrowing toenails, but reported recurrence rates vary from 16% to 50% (Townsend and Scott 1966; Andrew and Wallace 1979; Wallace, Milne and Andrew 1979; Morkane, Robertson and Inglis 1984; Pettine et al 1988). Recurrence is often caused by growth of a nail spike due to incomplete excision of the germinal matrix....

In response to concerns regarding arsenic in soil from a pesticide manufacturing plant, we conducted a biomonitoring study on children younger than 7 years of age, the age category of children most exposed to soil. Urine samples from 77 children (47% participation rate) were analyzed for total arsenic and arsenic species related to ingestion of inorganic arsenic. Older individuals also provided...
