statement of problem: physiologic pigmentation of oral mucosa is considered as a prevalent entity among black people and those having relatively dark skin. gingival physiologic pigmentation may cause problems for some patients specially ladies as far as esthetics is concerned. to overcome the issue, the surgery might be suggested which can cause some problems due to its side effects. cryotherap...

PURPOSE Hypertrophic scarring and depression are the principal problems of burn rehabilitation. This study was done to verify the effects of skin rehabilitation massage therapy (SRMT) on pruritus, skin status, and depression for Korean burn survivors. METHODS A pretest-posttest design using a nonequivalent control group was applied to examine the effects of SRMT for 3 months in a group of 18 ...

Mechanisms of animal skin pigment pattern formation have long been of interest to developmental and mathematical biologists. Although there has been a well-studied theoretical hypothesis—the reaction–diffusion system—that is able to reproduce the variety of skin patterns, a lack of molecular evieywords:

Skin pigmentary disorders and uneven skin tone represent common cosmetic concerns in Japan where fairer skin is culturally desirable. As the demographics of Asian countries continue to evolve, there is a need to understand the impact of cosmetic skin concerns on quality of life (QoL). 199 Japanese women self-claiming facial skin pigmentation disorders were asked to complete the BeautyQoL questi...

Background Lichen planus pigmentosus (LPP) is considered a chronic and progressive variant of lichen planus. Although pigmentation occurs in the sun exposed areas, the etiology remains unknown and there are no appropriate treatment guidelines. Association with thyroid disorder has been described in various disorders of pigmentation. Objective The objective of this study was to find the associat...

In Drosophila melanogaster, abdominal tergite pigmentation and the appearance of a trident-shaped thoracic pattern exhibit similar biogeographical variation and sensitivity to temperature. These pigmentation traits may be under common selection pressure in natural populations or may be genetically correlated. To investigate the nature of this interaction, replicated populations of D. melanogast...

Epidemiological studies have identified racial differences in susceptibility to numerous diseases, including several ocular and skin diseases characterized by increased vascular growth. In most cases, the specific mechanisms and genetic variants responsible for these differences have remained elusive. In this issue of the JCI, Adini et al. explore a direct connection between skin pigmentation a...

OBJECTIVES Alkaptonuria (AKU) is a genetic disorder caused by lack of the enzyme responsible for breaking down homogentisic acid (HGA), an intermediate in tyrosine metabolism. HGA is deposited as a polymer, termed ochronotic pigment, in collagenous tissues. Pigmentation is progressive over many years, leading to CTDs including severe arthropathies. To investigate the mechanism of pigmentation a...
