Streptococcus pyogenes, or group A Streptococcus, is a pathogen responsible for a wide range of clinical manifestations, from mild skin and soft tissue infections and pharyngitis to severe diseases. Its epidemiological characteristics should be comprehensively under surveillance for regulating the national prevention and treatment practice. Herein, a total of 140 S. pyogenes, including 38 invasive and 102 noninvasive isolates, were collected from infected patients in 10 tertiary general hospitals from 7 cities/provinces in China during the years 2009-2016...

BACKGROUND: Graft versus host disease (GVHD) is a significant complication following hematopoietic stem cell transplantation in the pediatric population. The most common clinical manifestation of GVHD is in the skin. This article will present a review of key concepts related to pediatric cutaneous GVHD, including pathophysiology, clinical epidemiology, diagnosis, and treatment options. GVHD is an immune-mediated process characterized by an inflammatory immune response in acute GVHD and mixed inflammatory and fibrotic states in chronic GVHD...

BACKGROUND: Skin autofluorescence, a biomarker for advanced glycation end products (AGEs) accumulation, has been shown to predict diabetes-related cardiovascular complications and is associated with several environmental and lifestyle factors. In the present study, we examined the association between various smoking behaviors and skin autofluorescence, as well as the association between several cotinine biomarkers and skin autofluorescence, using both epidemiological and metabolomics data...

BACKGROUND: Cutaneous larva migrans (CLM) is caused by the penetration and migration of canine or feline hookworm larvae into the skin, and frequently affects travelers from high-income countries returning from tropical and sub-tropical areas. Unfortunately, this pathology is neglected due to poor understanding among both physicians and travelers. This study describes the profile of cases reported in Marseille, France. PATIENTS AND METHODS: A retrospective study was performed in two specialized hospitals between 2003 and 2015...

REVIEW
Masutaka Furue, Takafumi Kadono
BACKGROUND: Comorbidities of cardiovascular diseases (CVDs), metabolic syndrome and autoimmune diseases with systemic inflammation are recent topics in medicine. Inflammatory skin diseases such as atopic dermatitis and psoriasis are an active source of diverse proinflammatory cytokines and chemokines, which are readily detectable in the circulation and are likely to be involved in developing comorbidities. EVIDENCE: Both atopic dermatitis and psoriasis are frequently comorbid with CVD, metabolic syndrome and autoimmune diseases, the consequence of which is called "inflammatory skin march", "psoriatic march" or "march of psoriasis"...

Few studies have addressed Leptospira seroprevalence and risk factors in urban populations in Colombia. This study aimed to determine seroprevalence and factors associated with Leptospira infection in inhabitants of an urban district of Cali, Colombia. We collected sociodemographic and environmental data, as well as blood samples, from 353 subjects selected through a multistage cluster sampling design. We performed microagglutination test for the eight main Leptospira serogroups circulating in the region, considering a cut-off titer of ≥ 1:100...

Anaphylaxis is an acute, life-threatening, multisystem syndrome resulting from the sudden release of mediators by mast cells and basophils. Although anaphylaxis is often under-communicated and thus underestimated, its incidence appears to have risen over recent decades. Drugs are among the most common triggers in adults, being analgesics and antibiotics the most common causal agents. Anaphylaxis can be caused by immunologic or non-immunologic mechanisms. Immunologic anaphylaxis can be mediated by IgE-dependent or -independent pathways...

PURPOSE OF REVIEW: Cutaneous sarcoidosis occurs in up to 30% of patients with sarcoidosis and skin findings are often the initial presenting symptom. Cutaneous sarcoidosis is a rare skin disease and many aspects of the disease presentation and treatment are not well understood. This review will highlight developments in the epidemiology, clinical presentation, diagnosis and treatment of cutaneous sarcoidosis over the past several years. RECENT FINDINGS: Epidemiological studies from several different populations reaffirm that cutaneous sarcoidosis is more common in women and is often the presenting symptom of systemic sarcoidosis...

Bacterial skin infections represent some of the most common infectious diseases globally. Prevention and treatment of skin infections can involve application of a topical antimicrobial, which may be an antibiotic (such as mupirocin or fusidic acid) or an antiseptic (such as chlorhexidine or alcohol). However, there is limited evidence to support the widespread prophylactic or therapeutic use of topical agents. Challenges involved in the use of topical antimicrobials include increasing rates of bacterial resistance, local hypersensitivity reactions (particularly to older agents, such as bacitracin), and concerns about the indiscriminate use of antiseptics potentially coselecting for antibiotic resistance...

Furocoumarins are a class of photoactive compounds found in several plant species and may be responsible for the observed association between consumption of citrus products and the risk of skin cancer. Furocoumarin contents of several foods have been reported previously, but no comprehensive database of furocoumarin content of foods is currently available. Therefore, this study aimed to determine the distribution of furocoumarins in popularly consumed foods in the U.S. Samples of three varieties of each of 29 foods known or suspected to contain furocoumarins were purchased, prepared for analysis using a solid phase extraction method, and analyzed using UPLC-MS/MS for the presence of seven major furocoumarins...

In recent years, the critical role that inflammation may play in the development and progression of acne has become increasingly recognized. The prevalence of acne is similar between Asian and Caucasian women, but Asian women have a higher prevalence of inflammatory acne. They also report their symptoms exacerbate during periods of high air pollution. The objective of this study was to review the current evidence that links air pollution to worsening of acne symptoms. Firstly, a group of five Asian and three European scientists with expertise in Dermatology reviewed the current literature and described current acne treatment practices in their countries...

Atopic dermatitis (AD) is a chronic inflammatory skin disorder with significant morbidity and quality-of-life impairment. The epidemiology of AD is complex and challenging to study. The 1-year US prevalence of AD was 12.98% in children in 2007-2008 and 7.2%-10.2% in adults in 2010-2012. There is considerable statewide and countrywide variation of AD prevalence and severity. The prevalence of childhood AD dramatically increased over the past few decades but may be leveling off in developed nations. AD is associated with increased direct and indirect costs to payers and patients, thereby contributing toward a considerable public health burden...
