Information about the epidemiology, clinical manifestations and comorbidities of sarcoidosis among Caucasians is relatively scarce. This review focuses primarily on the data from a recently published Caucasianpredominant population-based cohort from Olmsted County, Minnesota. Overall, the incidence rate was 10.0 per 100,000 population, which suggested that sarcoidosis is less common in Caucasians than in Blacks, but is more common in Caucasians than in Asians. Intrathoracic involvement was seen in the vast majority of patients, but less than half have respiratory symptoms...

Importance: Emergency department visits for skin infections in the United States have increased with the emergence of methicillin-resistant Staphylococcus aureus (MRSA). For cellulitis without purulent drainage, β-hemolytic streptococci are presumed to be the predominant pathogens. It is unknown if antimicrobial regimens possessing in vitro MRSA activity provide improved outcomes compared with treatments lacking MRSA activity. Objective: To determine whether cephalexin plus trimethoprim-sulfamethoxazole yields a higher clinical cure rate of uncomplicated cellulitis than cephalexin alone...

The purpose of this report is to document a unique location of an oropharyngeal foreign body, diagnosed via contrast computed tomography (CT), as well as a novel surgical approach to the pterygoid muscle region. Oropharyngeal foreign objects are an uncommon but potentially serious disease that can lead to chronic abscessation and pain. Two dogs were presented with chronic complaints, including pain and inability to fully open the mouth for a 1 yr and 5 mo duration, respectively. There was no history or evidence of skin sinus or submandibular/cervical swelling on physical examination of either dog...

Janis Spigulis
Optical tissue imaging has several advantages over the routine clinical imaging methods, including non-invasiveness (it does not change the structure of tissues), remote operation (it avoids infections) and the ability to quantify the tissue condition by means of specific image parameters. Dermatologists and other skin experts need compact (preferably pocket-size), self-sustaining and easy-to-use imaging devices. The operational principles and designs of ten portable in-vivo skin imaging prototypes developed at the Biophotonics Laboratory of Institute of Atomic Physics and Spectroscopy, University of Latvia during the recent five years are presented in this paper...

BACKGROUND: In Baltimore, MD, as in many cities throughout the USA, overdose rates are on the rise due to both the increase of prescription opioid abuse and that of fentanyl and other synthetic opioids in the drug market. Supervised injection facilities (SIFs) are a widely implemented public health intervention throughout the world, with 97 existing in 11 countries worldwide. Research has documented the public health, social, and economic benefits of SIFs, yet none exist in the USA. The purpose of this study is to model the health and financial costs and benefits of a hypothetical SIF in Baltimore...

Hansen's disease (HD) is an anthropophylic, infectious, chronic disease, caused by Mycobacterium leprae. The systemic disease, affecting both males and females at any age, involves mainly the skin and the peripheral nerves located in the limbs close to the skin. Traditionally the treatment of HD patients was entrusted to dermatologists. Current drug therapy given at an early stage can prevent many of the complications, and enables patients to go on with life. In 95% of the population there is an innate immunity, which following exposure, enables the development of an effective immune response preventing the development of overt clinical disease...

REVIEW
Jaiben George, Alison K Klika, Carlos A Higuera
Prosthetic joint infection (PJI) is a serious complication after total joint arthroplasty (TJA). Chlorhexidine is a widely used antiseptic because of its rapid and persistent action. It is well tolerated and available in different formulations at various concentrations. Chlorhexidine can be used for pre-operative skin cleansing, surgical site preparation, hand antisepsis of the surgical team and intra-articular irrigation of infected joints. The optimal intra-articular concentration of chlorhexidine gluconate in irrigation solution is 2%, to provide a persistent decrease in biofilm formation, though cytotoxicity might be an issue...

While some autoimmune disorders remain extremely rare, others largely predominate the epidemiology of human autoimmunity. Notably, these include psoriasis, diabetes, vitiligo, thyroiditis, rheumatoid arthritis and multiple sclerosis. Thus, despite the quasi-infinite number of "self" antigens that could theoretically trigger autoimmune responses, only a limited set of antigens, referred here as superautoantigens, induce pathogenic adaptive responses. Several lines of evidence reviewed in this paper indicate that, irrespective of the targeted organ (e...

The ESAT-6 secretion system (ESS) has been reported to contribute to the virulence and pathogenicity of several Staphylococcus aureus strains such as USA300 and Newman. However, the role of the ESS in community-associated S. aureus (CA-SA) lineage ST398 in China is not well understood. By comparing the ess locus of ST398 with the published S. aureus sequence in the NCBI database, we found one gene in the ess locus encoding a novel WXG superfamily protein that is highly conserved only in ST398. LC-MS/MS and Western blot analysis revealed that this protein is a novel secreted protein controlled by the ST398 ESS, and we named the protein EsxX...

Human papillomaviruses (HPV) are widespread DNA viruses that can infect epithelial cells of the skin and mucosa. Most HPV infections remain clinically unapparent and clear spontaneously. In few cases, however, HPV infections persist and can cause benign and malignant neoplasms at different anatomic locations. Malignant HPV-induced neoplasms are caused by distinct types of HPV (oncogenic or high-risk (HR) HPV types) and present in the anogenital (anus, penis, uterine cervix, vagina and vulva) and head and neck (particularly oropharynx) region...

Mycobacterium chelonae is a nontuberculous mycobacterium, classified as a Runyon type IV mycobacterium. In relation to humans, it is most commonly associated with tissue trauma or pulmonary infections. The majority of medical reports describe finding M. chelonae in the surgical setting, attributing infection to inadequate sterilization of surgical equipment. Symptoms are often nonspecific and include pain, erythema, and draining subcutaneous nodules and skin lesions. Therefore, the diagnosis of M. chelonae is often difficult to establish without prior suspicion of the disease, but can be confirmed with culture...

Fish skin is the largest immunologically active mucosal organ, providing first-line defense against external pathogens. However, the skin-associated immune mechanisms of fish are still unclear. Cryptocaryon irritans is an obligate ectoparasitic ciliated protozoan that infects almost all marine fish, and is believed to be an excellent pathogen model to study fish mucosal immunity. In this study, a de novo transcriptome assembly of Epinephelus coioides skin post C. irritans tail-infection was performed for the first time using the Illumina HiSeq™ 2500 system...
