Vitiligo is a skin condition characterized by white, hypopigmented macules. Melanocyte loss is a feature of the disease, and it has been hypothesized that an autoimmune mechanism could be responsible for the depigmentation. Melanoma is a malignancy that develops in melanocytes; if not detected and treated early, it is often deadly. Leukoderma, a condition characterized by depigmentation of the ...

OBJECTIVE Vitiligo is a rare side effect of carbamazepine whose exact mechanism is unknown. The aim of this report is to describe a single case of vitiligo induced by carbamazepine. METHODS The case was a patient with Bipolar I disorder whose medications were changed from valproate to carbamazepine and who developed vitiligo after a short while. We followed the case for about four years when ...

Two rare cases of Waardenburg type II are reported. First case had three main features of WS--profound SN hearing loss, hetrochromia iris and white forelock of hair. Second case had moderate SNHL and depigmentation of hair.

ISSN 0001-5555 Current therapy for vitiligo is largely unsatisfactory; hence there is a need for new treatment combinations to be assessed. Whereas stable vitiligo can benefit from surgical therapies, such as suction-blister epidermal grafting (SBEG) (1), the non-segmental counterpart usually s...

Tyrosinase is the key enzyme involved in the human pigmentation process, as well as the undesired browning of fruits and vegetables. Compounds inhibiting tyrosinase catalytic activity are an important class of cosmetic and dermatological agents which show high potential as depigmentation agents used for skin lightening. The multi-step protocol employed for the identification of novel tyrosinase...

Bilateral acute depigmentation of the iris (BADI) is a recently described entity characterized by acute onset of pigment dispersion in the anterior chamber, depigmentation of the iris, and heavy pigment deposition in the anterior chamber angle. Involvement is always bilateral, simultaneous, and symmetrical. We report the case of a 61-year-old man who presented with bilateral ocular pain, red ey...

A fungal pathogen Batrachochytrium dendrobatidis (Bd), which can cause morbidity and death of anurans, has affected amphibian populations on a worldwide basis. Availability of pure cultures of Bd isolates is essential for experimental studies to understand the ecology of this pathogen. We evaluated the relationships of body length of Hylodes cf. ornatus and Lithobates catesbeianus tadpoles to d...

Treatment for vitiligo is difficult and prolonged. Nevertheless, at present considerable knowledge accumulated during several decades on the pathogenic mechanisms, revealed important clues for designing new strategies to improve vitiligo depigmentation. With available medical therapies, high repigmentation percentages mostly on facial and neck lesions are achieved, although they are less effect...

Quinolones were first introduced in 1962, and their excellent oral absorption, good tissue distribution in tissue, and urinary concentrations, which exceed the minimum inhibitory concentration for many common pathogens, popularized their use in routine clinical practice. Structural modifications of quinolones resulted in improved pharmacokinetics, with a longer elimination half-life, which perm...
