Surprising reservoirs for skin disease;https://f1000.com/6066962?key=7fz9gp0pj4wzw7r Mycobacterium ulcerans, the causative agent of the skin disease Buruli ulcer (BU), can be transmitted via terrestrial mammals, such as possums, challenging the prevailing belief that BU is contracted from aquatic invertebrates and environments.J.A. Fyfe, et al., "A major role for mammals in the ecology of Mycobacterium ulcerans," linkurl:PLoS Negl Trop Dis,;https://www.ncbi.nlm.nih.gov/sites/entrez/20706592?dopt=Abstract&holding=f1000%2Cf1000m 4(8):e791, 2010.

Researchers identify a new subset of T helper (Th) 2 cells that produce interleukin (IL)-17. The results underline the plasticity of these Th cells and could hold implications for the treatment of allergic asthma, for which these cells may play a pathogenic role.Y.H. Wang, et al., "A novel subset of CD4(+) T(H)2 memory/effector cells that produce inflammatory IL-17 cytokine and promote the exacerbation of chronic allergic asthma," linkurl:J Exp Med,;https://www.ncbi.nlm.nih.gov/sites/entrez/20921287?dopt=Abstract&holding=f1000%2Cf1000m 207(11):2479-91, 2010.

Physical forces fuel healing;https://f1000.com/5752961?key=fc8k4mx06g5bd23 Integrin alpha11beta1, a receptor on fibroblast cells, is an important factor regulating the differentiation of a characteristic cell type of healing wounds and fibrotic tissue, and is regulated by physical forces in the cell and extracellular matrix.S. Carracedo, et al., "The fibroblast integrin alpha11beta1 is induced in a mechanosensitive manner involving activin A and regulates myofibroblast differentiation," linkurl:J Biol Chem,;https://www.ncbi.nlm.nih.gov/sites/entrez/20129924?dopt=Abstract&holding=f1000%2Cf1000m 285(14):10434-45, 2010.

How to handle increasing skin infections;https://f1000.com/5763957?key=9tf4xv2jv9yl6kp When it comes to preventing dangerous infections and the recent wave of antibiotic-resistant pathogens, doctors may be doing both too much and not enough. A review of adult patients hospitalized for complicated skin and soft tissue infections in 2007 reveals that doctors frequently take potentially unnecessary measures, such as diagnostic tests, broad-spectrum antibiotic therapy, and prolonged treatment courses, and suggests a need for antimicrobial stewardship programs.T.C. Jenkins, et al., "Skin and soft-tissue infections requiring hospitalization at an academic medical center: opportunities for antimicrobial stewardship," linkurl:Clin Infect Dis,;https://www.ncbi.nlm.nih.gov/sites/entrez/20839951?dopt=Abstract&holding=f1000%2Cf1000m 51(8):895-903, 2010.

Key factor for natural moisturizers;https://f1000.com/6051956?key=wmjzxzftwyl9ph0 Bleomycin hydrolase (BH) is a key enzyme for the production of natural moisturizing factors in the skin that are critical for maintaining epidermal hydration. The results may have important implications for the treatment of various skin diseases.Y. Kamata, et al., "Neutral cysteine protease bleomycin hydrolase is essential for the breakdown of deiminated filaggrin into amino acids," linkurl:J Biol Chem,;https://www.ncbi.nlm.nih.gov/sites/entrez/19286660?dopt=Abstract&holding=f1000%2Cf1000m 284(19):12829-36, 2009.

Fatal disease from transplant;https://f1000.com/5966959?key=9jb919ym6d5xfkr The Center for Disease Control and Prevention (CDC) reports the first known transmission of a rare disease caused by Balamuthia mandrillaris, a free-living amoeba found in soil, via organ transplantation. Two kidney transplant recipients contracted the disease, one of whom died, highlighting the importance of awareness of this potentially fatal infection during organ transplantation.CDC, "Balamuthia mandrillaris transmitted through organ transplantation --- Mississippi, 2009," linkurl:MMWR Morb Mortal Wkly Rep,;https://www.ncbi.nlm.nih.gov/sites/entrez/20847719?dopt=Abstract&holding=f1000%2Cf1000m 59:1165-70, 2010.

Defining a new clinical condition;https://f1000.com/5967957?key=k34p61wyrq7knnj Mast cell activation syndrome (MCAS) has been used as a default diagnosis for patients with skin, gastrointestinal, cardiovascular, respiratory and/or neurologic symptoms that can be associated with the activation of mast cells. Here, the authors attempt to define the syndrome and propose criteria for its diagnosis, presenting a framework for further investigation.C. Akin, et al., "Mast cell activation syndrome: Proposed diagnostic criteria," linkurl:J Allergy Clin Immunol,;https://www.ncbi.nlm.nih.gov/sites/entrez/21035176?dopt=Abstract&holding=f1000%2Cf1000m 2010.
