Lichen planus and vitiligo are common skin disorders. Colocalization which is rarely reported may consider the koebner phenomenon related to the photo damage causing initiation of lichen planus over vitiliginous skin. We report a 37-year-old mother and her 23-year-old daughter, both farmers and known cases of vitiligo with subsequent gradual onset of pruritic skin lesions of lichen planus start...

A 34 year man presented to us with itchy lesions on one half of the trunk for the past two months. The lesions started as erythematous to violaceous papules and plaques on the flank and gradually increased in number to involve the left side of the trunk (Figure 1 and 2). Some areas showed the Koebner phenomenon. These lesions were distributed along the lines of Blaschko. Examination of the oral...

All new cases of vitiligo reporting to Dermatology Outpatient of Combined Military Hospital, Panu Aqil, were included in the study. Of the 230 patients, 124 were male (53.9%) and 106 were female (46.1%). Males were more commonly affected. The disease affected all age groups. Mean age at presentation was 27.02 + 18.34 years and age at presentation ranged from 5.5 months to 82 years. The mean age...

Based on striking parallels between the cell kinetics in the epidermal lesion of psoriasis and the proliferation of hair matrix keratinocytes during the anagen phase of the hair growth cycle, the hypothesis is proposed that both phenomena may share the same "switch-on" mechanism. Particular emphasis is placed on a comparison between the Koebner phenomenon in psoriasis and wounding-induced anage...

Reverse addressing is an interesting realization of kinship terms in interactive, face to face communication. This descriptive study was proposed to examine the use of family address pronouns in Iran as a function of the classical sociological parameters of age, sex, and social distance. It investigated various aspects of reverse addressing as a vernacular phenomenon. Data were reported from th...

Many traditional and new musical instruments make use of an isomorphic note layout across a uniform planar tessellation. Recently, a number of hexagonal isomorphic keyboards have become available commercially. Each such keyboard or interface uses a single specific layout for notes, with specific justifications as to why this or that layout is better. This paper is an exploration of all possible...
