( fig. 2 ) as well as Sabouraud culture yeast colonies with a brain-shaped appearance that were identified as Trichosporon spp. The affected hairs were examined by dermoscopy that showed fusiform and yellow nodules of Trichosporon spp. around the hair shaft and attached to the distal parts of the hair ( fig. 3 ). The patient was treated with itraconazole 100 mg/day and topical selenium sulfur s...

A retrospective study was performed on potbellied pigs with skin disease over a 22-year period. Thirteen of 190 pigs (7%) were examined by the Dermatology Service. Three different dermatoses were diagnosed: (1) sarcoptic mange, (2) yeast dermatitis of the eyelids (blepharitis) and periocular skin, and (3) presumed ichthyosis. Sarcoptic mange was cured with ivermectin injections. Yeast dermatiti...

In this study, enzymatic hydrolysis and cationization with epoxypropyldodecyldimethylammonium chloride of wheat protein, an economic protein complex containing great amount of disulfide bonds, were conducted to improve properties such as solubility and disassociation behaviour for recovery of damaged hair when used in shampoo. The optimal conditions for enzymatic hydrolysis were pH 8.2, 55°C wi...

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (i...

White piedra is a rare fungal infection of the hair shaft characterized by small, firm, irregular white-brown nodules. The infection is caused by basidiomycetous yeasts in the genus Trichosporon. We report a case of a 28-year-old female patient who acquired the infection in Qatar. In this case, the scalp was the only site affected, but infection at that site was extensive. The hair had a Saccha...
