There is no single malady which causes supplementary psychic disturbance and more general insecurity and feeling of inferiority than acne vulgaris with post inflammatory acne pigmentation marks does. It is strongly associated with depression and anxiety. In addition to individuals with little objective evidence acne with post inflammatory acne hyperpigmentation marks may endure severe subjectiv...
BACKGROUND Conventional short-pulsed Er:YAG lasers show less effective hemostasis and weak photothermal damage on papillary dermis. Recently, newer long-pulsed Er:YAG laser systems has been developed. OBJECTIVE To evaluate the clinical and histologic effects of long-pulsed Er:YAG laser resurfacing for pitted facial acne scars. METHODS Thirty-five patients with pitted facial acne scars were ...
Facial rhytides are a common problem that often presents for treatment. Because of the tendency for rhytides to involve delicate tissue areas, traditional treatment modalities have been limited by complications of scarring or pigmentary alterations. With the advent of the new-generation high-energy pulsed carbon dioxide lasers, skin requiring resurfacing can now be treated successfully with min...
introduction: tessier facial cleft is among the rarest facial clefts reported in literatures and there are many issues arguing about its multidisciplinary repairing techniques. tessier number 4 and 5 are extremely rare facial anomalies. there are few literatures describing these clefts and their surgical modalities. number 5 tessier cleft begins medial to oral commissure in the upper lip and ex...
Postinflammatory hyperpigmentation is a common sequelae of inflammatory dermatoses that tends to affect darker skinned patients with greater frequency and severity. Epidemiological studies show that dyschromias, including postinflammatory hyperpigmentation, are among the most common reasons darker racial/ethnic groups seek the care of a dermatologist.

We previously reported that three point mutations in SASH1 and mutated SASH1 promote melanocyte migration in dyschromatosis universalis hereditaria (DUH) and a novel p53/POMC/Gαs/SASH1 autoregulatory positive feedback loop is regulated by SASH1 mutations to induce pathological hyperpigmentation phenotype. However, the underlying mechanism of molecular regulation to cause this hyperpigmentation ...
