The world is flat when it comes to aesthetic treatments, meaning women and men from all walks of life, regardless of culture and ethnicity or even socioeconomic status, are seeking ways to improve their appearance, prevent aging, and rejuvenate their skin. Year after year, statistics show a steady increase in people of color undergoing aesthetic treatments, with neurotoxins, fillers, laser resurfacing, and body contouring being the most sought-after procedures. When treating this cohort of patients, however, dermatologists need to be sensitized to how a patient's ethnicity affects facial structure, the tissue reaction to treatments, and patient's specific expectations for recommended therapies.

Facial lichen planus pigmentosus (LPPig), a rare variant of classic lichen planus, was first described in patients with frontal fibrosing alopecia (FFA) by Dlova [Br J Dermatol 2013; 168: 439-442] in 2013. The diagnosis of facial LPPig is sometimes not easy, since clinical signs and histopathological features may frequently be confused with melasma or postinflammatory hyperpigmentation. We describe a case of a postmenopausal black woman diagnosed with FFA who presented with an identical brown-grayish pigmentation of the face and upper eyelids and typical dermoscopy analysis on both regions.

Postinflammatory hyperpigmentation (PIH) and erythema are the most common adverse effects associated with laser treatment, particularly in dark-skinned individuals. Several methods have been used to prevent or minimize these adverse effects; however, to date, no definitive precautions/strategies are known to prevent post-laser PIH and erythema. We investigated whether the topical application of the α-adrenergic receptor agonist brimonidine could reduce laser treatment-related complications such as erythema and PIH. Read More

Background: Pigmentation of the skin occurs as a result of increased melanin production or deposition due to various reasons including age, hormonal imbalances, endocrine disease, inflammation, and/or exposure to damaging radiation, resulting in dermatologic conditions such as lentigines, melasma, or postinflammatory hyperpigmentation. Although numerous topical therapies exist for skin lightening, they are limited by efficacy and pigmentation recurrence after treatment cessation.

Color differences in skin are due to the amount and distribution of epidermal melanin. The number of melanocytes is almost the same in all skin types, but higher phototypes exhibit more melanocytes, which produce more melanin and melanosomes that are individually distributed throughout the keratinocyte layers. This characteristic ensures a natural, significant photoprotection in darker skins. Read More

We report a case of Cogan's syndrome presenting as fever of unknown origin in a 31-year-old woman who was admitted to the hospital with a 7-week history of fever, night sweats and other constitutional symptoms. The diagnosis remained elusive despite numerous investigations, and the patient subsequently developed rash, episcleritis, dizziness and sensorineural hearing loss. While initially thought to be a postinflammatory response to a previous infection, confirmation of the rash as a vasculitis together with the audiovestibular and ocular involvement led to a clinical diagnosis of Cogan's syndrome.

The presence of a fecal pellet in the colorectum causes ascending contraction and descending relaxation, propelling the pellet aborally. However, random occurrence of the reflexes at multiple sites would disturb sequential excretion of the pellets, resulting in inefficient defecation. Hence, we postulated that a regulatory mechanism to coordinate peristaltic motility initiated at adjacent portions of the colorectum may exist. Read More
