Clindamycin is a lincomycin-derived antibiotic useful for the treatment of anaerobic and Gram-positive aerobic bacterial infections. Cutaneous adverse reactions are usually maculopapular exanthemas, although hypersensitivity syndrome, acute generalized exanthematous pustulosis, and Stevens-Johnson syndrome have also been reported (1). We report the case of a patient with a maculopapular rash triggered by clindamycin who developed cutaneous lesions on striae distensae (SD). A 47-year-old woman was referred to our clinic for pruritic cutaneous lesions which had started 6 days earlier...

Surgically induced fire is a life-threatening hazard; this topic has received little attention, although only 3 factors, the so-called fire triad, are needed for surgical fires to occur: an oxidizer, fuel and an ignition source. This systematic review aims to determine the impact of each component and to delegate every staff member an area of responsibility, thus ensuring patient health through prevention or protection. The trial was registered in Prospero CRD42018082656. A database search of eligible, preferably evidence-based studies was conducted...

Background: Diisocyanates (isocyanates), including methylene diphenyl diisocyanate (MDI), are the primary reactive components of spray polyurethane foam (SPF) insulation. They are potent immune sensitizers and a leading cause of occupational asthma. Skin exposure to isocyanates may lead to both irritant and allergic contact dermatitis and possibly contribute to systemic sensitization. More than sufficient evidence exists to justify the use of protective garments to minimize skin contact with aerosolized and raw isocyanate containing materials during SPF applications...

The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of magnesium sulfate, which functions as a bulking agent in cosmetic products and is reportedly used at concentrations up to 11% and 25% in leave-on and rinse-off products, respectively. The Panel noted that the history of safe medical use of magnesium sulfate provides further confidence that there are no significant toxicity concerns relating to systemic exposure to this ingredient after cosmetic product application. Furthermore, the extensive clinical experience of the Panel, including the results of numerous patch tests, indicates that magnesium salts do not have the potential to induce sensitization...

Introduction: Psoriasis is a common, chronic inflammatory disease characterised by typical scaly skin lesions. The role of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in the pathogenesis and development of this condition have been repeatedly emphasised in available literature. Aim: ROC analysis of selected MMPs (MMP-2, MMP-3, MMP-9, MMP-12, TIMP-2) and TIMPs (TIMP-2, TIMP-3) in psoriasis patients. The area under the ROC curve (AUC) indicates the clinical usefulness of a biomarker and its diagnostic power...

A series of fourteen novel synthesized arylazothiazole and arylhydrazothiazole derivatives were tested for their antifungal activity and structure-activity relationship. The activity of the compounds depends mainly on the side chains of the nucleus compound. The antifungal activity was more significant when both side chains are aromatic > one aromatic and one aliphatic and substituted aromatic with CH3 or OCH3  > non-substituted > substituted aromatic with chloro- or nitro-groups. Thiazole derivatives 7a, 7c, 7e, 7f, 7 g, 7i, 7 m, and 11a showed the most effective as antifungal compounds and were comparable with fluconazole as antifungal reference drug when investigated against Candida albicans, Microsporum gypseum and Trichophyton mentagrophytes...

OBJECTIVE: Introduction:Psoriasis affects about 2% of population. In 30-40% of occurrences arthropathic psoriasis (AP) is diagnosed and it leads to 11-19% of disability cases development. Recent studies have shown that psoriasis is often synergistically combined with herpesvirus of the 1st and 2nd type, which, according to many scientists, determines the severity, frequency of recurrences, and the course of this dermatosis. Recently, new biomarkers, i.e. a system of small ribonucleic microRNA acids, have been described...

Protothecosis is an unusual infection of both humans and animals caused by opportunistically pathogenic microalgae of the genus Prototheca . Until now, no standardized treatment protocols exist for the protothecal disease, boosted by a remarkable resistance of Prototheca spp. to a wide array of antimicrobial agents currently available in clinical use. Consequently, there is an urgent need for new effective drugs against Prototheca algae. In this study, the anti- Prototheca activity of 3-bromopyruvate (3BP), either alone or in combination with amphotericin B (AMB) was assessed in vitro , as well as the cytotoxicity of 3BP toward the bovine mammary epithelial cells and murine skin fibroblasts...
