International expert consensus recommendations for the use of dermocosmetics in acne.

Background: A wide variety of dermocosmetics (products with both active skincare and cosmetic activity) are available for the management of acne vulgaris. These products are important because they may be the first line of approach for patients desiring to self-treat and they can also have beneficial effects-reducing lesion counts and improving global acne severity. When used in conjunction with medical therapy, dermocosmetics can improve tolerability and enhance results.

Pseudomonas syringae coffee blight is associated with the horizontal transfer of plasmid-encoded type III effectors.

The emergence of new pathogens is an ongoing threat to human health and agriculture. While zoonotic spillovers received considerable attention, the emergence of crop diseases is less well studied. Here, we identify genomic factors associated with the emergence of Pseudomonas syringae bacterial blight of coffee.

Safety review of phenoxyethanol when used as a preservative in cosmetics.

Phenoxyethanol, or 2-phenoxyethanol, has a large spectrum of antimicrobial activity and has been widely used as a preservative in cosmetic products for decades. It is effective against various Gram-negative and Gram-positive bacteria, as well as against yeasts, and has only a weak inhibitory effect on resident skin flora. According to the European Scientific Committee on Consumer Safety, phenoxyethanol is safe for all consumers - including children of all ages - when used as a preservative in cosmetic products at a maximum concentration of 1%.

The impact of airborne pollution on skin.

Indoor and outdoor airborne pollutants modify our environment and represent a growing threat to human health worldwide. Airborne pollution effects on respiratory and cardiac health and diseases have been well established, but its impact on skin remains poorly described. Nonetheless, the skin is one of the main targets of pollutants, which reach the superficial and deeper skin layers by transcutaneous and systemic routes.

Indication guidelines for Mohs micrographic surgery in skin tumors.

Mohs micrographic surgery is a technique used to excise skin tumors based on comprehensive surgical mapping, in which the surgeon removes the tumor, followed by a complete histological evaluation of the tumor's margins. The correlation of the presence of a tumor in histological examinations and its precise location on the surgical map result in a complete removal of the tumor with maximum normal tissue preservation. The present article seeks to provide general practitioners and healthcare specialists with guidelines regarding recommendations for Mohs micrographic surgery to treat skin tumors, based on the most reliable evidence available in medical literature on the subject.

Microbiome in healthy skin, update for dermatologists.

The skin is a complex barrier organ made of a symbiotic relationship between microbial communities and host tissue via complex signals provided by the innate and the adaptive immune systems. It is constantly exposed to various endogenous and exogenous factors which impact this balanced system potentially leading to inflammatory skin conditions comprising infections, allergies or autoimmune diseases. Unlike the gut and stool microbiome which has been studied and described for many years, investigations on the skin or scalp microbiome only started recently.

[Gitelman's Syndrome: from diagnosis to follow-up during pregnancy].

Gitelman's Syndrome (GS) is a rare autosomal recessive salt-wasting nephropathy, classically characterized by hypokalemia, hypomagnesemia, hypocalciuria, metabolic alkalosis and low blood pressure. Fatigue, muscle weakness and muscle paralysis are common symptoms. Besides the typical electrolyte disturbances, others laboratory findings include hyperreninemia and secondary hyperaldosteronism.

Bannayan-Riley-Ruvalcaba syndrome with deforming lipomatous hamartomas in infant--case report.

Bannayan-Riley-Ruvalcaba Syndrome is a rare condition caused by mutations in the PTEN gene. It displays association of multiple lipomas, macrocephaly, hemangiomas, hamartomatous intestinal polyposis, developmental delay and speckled pigmented maculae on the male genitalia. We report the case of a nine-month-old boy who had fast growing and progressive tumors for three months, macrocephaly and lentigines on the penis.

Non-cultured melanocyte/keratinocyte transplantation for the treatment of stable vitiligo on the face: report of two cases.

There are many alternatives to treat vitiligo, including surgical procedures, which are recommended for patients resistant to other therapies. The melanocyte/keratinocyte transplantation consists in the separation of epidermal cells obtained from a donor site and spreading these cells on the depigmented and dermabraded recipient area. Two patients were submitted to transplantation, showing more than 70% repigmentation in the treated areas after four months, both with excellent degree of satisfaction.

Do you know this syndrome?

The Bourneville-Pringle syndrome is an autosomal dominant neurocutaneous disorder characterized by the development of multiple hamartomas in various systems, especially brain, skin, retina, kidney, heart and lung. The case of a patient with brownish plaques on the forehead and temporal region, pink malar and chin papules, and hypopigmented macules on the back and trunk is described. The diagnosis of the Bourneville-Pringle syndrome is based on clinical criteria.

Notalgia paraesthetica: a descriptive two-cohort study of 65 patients from Brazil and Germany.

Notalgia paraesthetica is a neuropathic pruritus on the back. The aim of this retrospective study was to examine patient characteristics in a consecutive cohort from Brazil and Germany. A total of 65 patients (49 women, 16 men; age range 25-80 years, mean 56.

Disabling acne fulminans.

Acne fulminans is a rare manifestation that may occur during the evolution of acne vulgaris primarily in male adolescents. Use of isotretinoin, testosterone, and exacerbated immune responses in the body are related triggers. Signs, symptoms and laboratory findings such as fever, hepatomegaly, polyarthralgia, leukocytosis, plaquetose, increased inflammatory markers and transaminases, are characteristic.
