The novel picosecond lasers, initially developed for faster tattoo removal, have also shown great efficacy in endogenous pigmentary disorders. To describe the efficacy and safety profile of an alexandrite (755-nm) picosecond laser in a wide range of pigmented flat and elevated cutaneous lesions. A retrospective study was performed in which we collected all the clinical images of patients treated with the 755-nm alexandrite picosecond laser for 12 months (November 2016-November 2017). Clinical features were obtained from their medical charts...

Pityriasis rosea is a common self-limiting rash that usually starts with a herald patch on the trunk and progresses along the Langer lines to a generalized rash over the trunk and limbs. The diagnosis is based on clinical and physical examination findings. The herald patch is an erythematous lesion with an elevated border and depressed center. The generalized rash usually presents two weeks after the herald patch. Patients can develop general malaise, fatigue, nausea, headaches, joint pain, enlarged lymph nodes, fever, and sore throat before or during the course of the rash...

OBJECTIVE: The objective was to determine if the type and number of skin diseases can be clinical indicators of underlying immune status in HIV1 disease by estimating and correlating with the CD4 count and CDC stage. MATERIALS AND METHODS: This was a retrospective cross-sectional descriptive study. All consecutive patients infected with HIV1 followed at the Dermatology Department of Rabat Military Hospital between January 2008 and January 2017 were studied for dermatological manifestations, CD4 count and CDC clinical stage...

The skin of mammalian organisms is home for a myriad of microbes. Many of these commensals are thought to have beneficial effects on the host by critically contributing to immune homeostasis. Consequently, dysbiosis can have detrimental effects for the host that may manifest with inflammatory diseases at the barrier tissue. Besides bacteria, fungi make an important contribution to the microbiota and among these, the yeast Malassezia widely dominates in most areas of the skin in healthy individuals. There is accumulating evidence that Malassezia spp...

Seborrheic Dermatitis (SD) is a common inflammatory skin disease that presents as itchy, flaking skin in the seborrheic areas. Various environmental and intrinsic factors have been identified as predisposing factors for SD, but its etiology remains poorly understood. Although it was recognized that genetic factors play a role in SD etiology, there have not been studies that systematically review the literature specifically for causal mutations or protein deficiencies in SD. In this review, we searched various databases for gene mutations and protein deficiencies that cause SD or SD-like phenotype in humans and experimental animals, and summarize 11 gene mutations or protein deficiencies that were described in the literature...

Dasatinib is an oral tyrosine kinase inhibitor approved for imatinib-resistant chronic myelogenous leukemia. It has been investigated in treating other neoplasms, including non-small-cell lung cancer and a subset of melanomas. Seborrheic dermatitis is characterized by erythematous patches or plaques with scaling typically affecting the external ear, glabella, hair-bearing areas of the face, nasolabial fold, and scalp. Antitumor agents are often associated with mucocutaneous side effects, including seborrheic dermatitis...

BACKGROUND: Mucocutaneous manifestations are one of the first clinical signs in patients infected with human immunodeficiency virus (HIV). To the best of our knowledge, there has been no previous study describing dermatologic manifestations in Mauritanians infected with HIV. The aim of the present study was to determine the profiles of mucocutaneous manifestations in relation to CD4 T cell count in HIV-positive Mauritanian patients. METHODS: A total of 86 adult patients aged > 18 years old attending the Ambulatory Treatment Center of the National Hospital of Nouakchott, Mauritania, with newly diagnosed HIV and who were not under antiretroviral treatment were included in the study in 2015...

BACKGROUND AND PURPOSE: Seborrheic dermatitis is a chronic and recurrent superficial dermatitis in which Malassezia species play an important role. There are different Malassezia species, which have been recently reported to be resistant to common antifungals. Natural sources can be useful alternatives to reduce the emergence of this resistance. Kombucha tea is believed to have potential antimicrobial properties. Regarding this, the present study aimed to investigate the antifungal activity of Kombucha tea ethyl acetate fraction (KEAF) against Malassezia species obtained from the patients with seborrheic dermatitis...

Malassezia species are lipophilic and lipid-dependent yeasts belonging to the human and animal microbiota. Typically, they are isolated from regions rich in sebaceous glands. They have been associated with dermatological diseases such as seborrheic dermatitis, pityriasis versicolor, atopic dermatitis, and folliculitis. The genomes of Malassezia globosa, Malassezia sympodialis, and Malassezia pachydermatis lack the genes related to fatty acid synthesis. Here, the lipid-synthesis pathways of these species, as well as of Malassezia furfur, and of an atypical M...

Approximately 30% of Canadians will be members of a visible minority by 2031. When dermatology became an independent medical discipline in the late 18th and early 19th centuries, most residents of Canada and the United States were of Northern European descent. Morphology and descriptions of dermatoses are based on patients with light skin. Skin of colour dermatology refers to a unique field in dermatology dedicated to the diagnosis and management of disorders that are more prevalent in patients with moderately to richly pigmented skin...

As increasing numbers of patients of African descent seek treatment for hair and scalp-related diseases, it is imperative that all dermatologists be adequately trained to address the concerns of this patient population. We present must-know information to effectively approach the concerns of patients with seborrheic dermatitis, acquired trichorrhexis nodosa, acne keloidalis nuchae, pseudofolliculitis barbae, alopecia, and common pediatric hair and scalp disorders.

This contribution describes hidradenitis suppurativa (HS) occurring in Down disease that presented with morphology conforming to an overlap of stages 1 and 2 of the Hurley staging system, namely the formation of solitary or multiple isolated abscesses without scarring or sinus tracts, recurrent abscesses, and single or multiple widely separated lesions with sinus tract formation, occupying apocrine sweat gland-bearing areas: the inner thighs, groin, and buttocks. The lesions were bilateral and symmetrical, of rare occurrence...

Seborrheic dermatitis is an inflammatory and chronic disease with a high incidence and prevalence (1% to 3% in the general population, 3% to 5% in young adults, and 40% to 80% in HIV-positive individuals). Although the condition was first described in 1887, its clinical aspects and clinical forms have still not been well individualized, nor has its etiopathogenesis been fully elucidated. The disease, despite having clinical features similar to dermatitis, does not have the same histopathologic features or the same progressive clinical behavior...

The human body is inhabited by complex microbial communities, which positively impact different aspects of our health, and might also be related to the development of diseases. Progress in technologies, particularly sequencing methods and bioinformatics tools, has been crucial for the advances in this field. Microbial communities from skin can modulate immune response and protect the host against pathogens, and there are also data supporting their association with several skin conditions; including dandruff and seborrheic dermatitis...

BACKGROUND: Seborrheic dermatitis (SD) is a common inflammatory skin condition. The etiology is unclear, although overgrowth of Malassezia on the skin has been suggested to cause SD. This study investigated whether colonization with Staphylococcus plays a role in facial SD, which was not well addressed previously. METHODS: The study was conducted from September 1, 2011 to February 20, 2012 in the First Hospital of China Medical University. In the first phase, the study evaluated the level of transepidermal water loss (TEWL) and the number of colony-forming units (CFU) of Staphylococcus in defined skin areas of SD patients who were human immunodeficiency virus (HIV) seropositive (HIV [+] SD [+] group, n = 13), classical SD (HIV [-] SD [+] group, n = 24) patients, HIV seropositive-non-SD (HIV [+] SD [-] group, n = 16) patients, and healthy volunteers (HIV [-] SD [-] group, n = 16)...
