A randomized phase 3b/4 study to evaluate concomitant use of topical ivermectin 1% cream and doxycycline 40-mg modified-release capsules, versus topical ivermectin 1% cream and placebo in the treatment of severe rosacea.

Background: Randomized controlled studies of combination therapies in rosacea are limited.

Objective: Evaluate the efficacy and safety of combining ivermectin 1% cream (IVM) and doxycycline 40-mg modified-release capsules (ie, 30-mg immediate-release and 10-mg delayed-release beads) (DMR) versus IVM and placebo for treatment of severe rosacea.

Methods: This 12-week, multicenter, randomized, investigator-blinded, parallel-group comparative study randomized adult subjects with severe rosacea (Investigator's Global Assessment [IGA] score, 4) to receive either IVM and DMR (combination arm) or IVM and placebo (monotherapy).

Results from a pooled analysis of two European, randomized, placebo-controlled, phase 3 studies of ATX-101 for the pharmacologic reduction of excess submental fat.

Background: The injectable adipocytolytic drug ATX-101 is the first nonsurgical treatment for the reduction of submental fat (SMF) to undergo comprehensive clinical evaluation. This study aimed to confirm the efficacy and safety of ATX-101 for SMF reduction through a post hoc pooled analysis of two large phase 3 studies.

Methods: Patients with unwanted SMF were randomized to receive 1 or 2 mg/cm(2) of ATX-101 or a placebo injected into their SMF during a maximum of four treatment sessions spaced approximately 28 days apart, with a 12-week follow-up period.

Azelaic acid foam 15% in the treatment of papulopustular rosacea: a randomized, double-blind, vehicle-controlled study.

Rosacea is a common chronic inflammatory skin disease that primarily affects facial skin. Its etiology is unknown, and currently there is no cure. Rosacea can be associated with severe symptoms, including transient erythema (flushing), nontransient erythema, papules, pustules, and telangiectases, leading to substantial discomfort and an unattractive appearance.

A human folliculoid microsphere assay for exploring epithelial- mesenchymal interactions in the human hair follicle.

The search for more effective drugs for the management of common hair growth disorders remains a top priority, both for clinical dermatology and industry. In this pilot study, we report a pragmatic organotypic assay for basic and applied hair research. The patented technique produces microdroplets, which generate human folliculoid microspheres (HFMs), consisting of human dermal papilla fibroblasts and outer root sheath keratinocytes within an extracellular matrix that simulates elements of the hair follicle mesenchyme.

The advantages of topical combination therapy in the treatment of inflammatory dermatomycoses.

Dermatomycoses are contagious superficial fungal infections, which are highly prevalent in developed and developing countries. Caused by a range of Epidermophyton, Microsporum and Trichophyton species, dermatomycoses manifest on glabrous skin as 'ringworm', an annular scaly lesion with a variable inflammatory component. Itch is the chief subjective symptom, particularly in tinea cruris.

Epidemiological trends in skin mycoses worldwide.

Fungal infections of the skin and nails are a common global problem. The high prevalence of superficial mycotic infections shows that 20-25% of the world's population has skin mycoses, making these one of the most frequent forms of infection. Pathogens responsible for skin mycoses are primarily anthropophilic and zoophilic dermatophytes from the genera Trichophyton (T.

Matrix metalloproteinase-19 expression in normal and diseased skin: dysregulation by epidermal proliferation.

Most of the matrix metalloproteinases (MMP) are not expressed in normal intact skin but they are upregulated in inflamed or diseased skin. The recently cloned MMP-19 is one of the few MMP members that are also expressed in healthy epidermis. In this study, we found that MMP-19 is generally coexpressed with cytokeratin 14 that is confined to keratinocytes of the stratum basale.
