Background: Infections of skin and soft tissue (SSTI) commonly cause visits to hospital emergency departments (EDs). The Infectious Diseases Society of America (IDSA) has published guidelines for the management of SSTI, but it is unclear how closely these guidelines are followed in practice. Methods: We reviewed records of patients seen in the ED at a large tertiary care hospital to determine guidelines adherence in 4 important areas: the decision to hospitalize, choice of antibiotics, incision and drainage (I&D) of abscesses, and submission of specimens for culture...

The 2014 to 2016 Ebola outbreak, primarily based in 3 West African countries, had far-reaching global effects. Importantly, the crisis highlighted large gaps in reproductive health services in affected countries and inadequate health care system preparedness for obstetrical patients in the setting of highly contagious infectious diseases. We aim to review Ebola virus effects with a focus on the obstetrical implications in the context of this recent Ebola outbreak, discuss the lessons learned following this outbreak and propose current measures specific to obstetrics that should be considered in preparation for the next concerning emergent infectious disease...

During outbreaks of deadly emerging pathogens (e.g., Ebola, MERS-CoV) and bioterror threats (e.g., smallpox), actively monitoring potentially infected individuals aims to limit disease transmission and morbidity. Guidance issued by CDC on active monitoring was a cornerstone of its response to the West Africa Ebola outbreak. There are limited data on how to balance the costs and performance of this important public health activity. We present a framework that estimates the risks and costs of specific durations of active monitoring for pathogens of significant public health concern...

The continual emergence of new pathogens and the increased spread of antibiotic resistance in bacterial populations remind us that microbes are living entities that evolve at rates that impact public health interventions. Following the historical thread of the works of Pasteur and Darwin shows how reconciling clinical microbiology, ecology, and evolution can be instrumental to understanding pathology, developing new therapies, and prolonging the efficiency of existing ones.

OBJECTIVES: Physicians of many specialties encounter patients treated with immunomodulatory medications and must weigh the risk of infection when making medical decisions. We explored how physician perceptions of the infection risk of immunomodulatory medications differ by specialty and level of experience. METHODS: A survey was distributed to physicians from the internal medicine, family medicine, emergency medicine, rheumatology, dermatology, and infectious disease departments at 1 tertiary care institution...

Macrophages are linchpins of innate immunity, responding to invading microorganisms by initiating coordinated inflammatory and antimicrobial programs. Immediate antimicrobial responses, such as NADPH-dependent reactive oxygen species (ROS), are triggered upon phagocytic receptor engagement. Macrophages also detect and respond to microbial products through pattern recognition receptors (PRRs), such as TLRs. TLR signaling influences multiple biological processes including antigen presentation, cell survival, inflammation, and direct antimicrobial responses...

As a newly emerged infectious disease, duck "beak atrophy and dwarfism syndrome (BADS)" disease has caused huge economic losses to waterfowl industry in China since 2015. Novel goose parvovirus-related virus (NGPV) is believed the main pathogen of BADS disease; however, BADS is rarely reproduced by infecting ducks with NGPV alone. As avian circovirus infection causes clinical symptoms similar to BADS, duck circovirus (DuCV) is suspected the minor pathogen of BADS disease. In this study, an investigation was carried out to determine the coinfection of NGPV and DuCV in duck embryos and in ducks with BADS disease...

INTRODUCTION: Illegal gold mining is flourishing in French Guiana, existing outside the law due to both the high cost of gold mining permits and the challenges of law enforcement within the Amazon forest. We report the characteristics of, and the medical responses to, medical emergencies in illegal gold mining sites. METHODS: We performed a retrospective study of all medical emergencies reported from illegal gold mining sites to the centralized call office of SAMU 973 from 1998 through 2000 and from 2008 through 2010...

The 2014-2016 Ebola virus outbreak in West Africa led to advances in the development of vaccines against Ebola. This study examined factors associated with willingness to pay for an Ebola vaccine among a U.S. national sample during the recent Ebola outbreak. From April 30-May 8, 2015, a national survey was conducted using the GfK Group's KnowlegePanel®. Main outcome measures included willingness to pay at least $1; more than $50; and more than $100 for an Ebola vaccine. Analyses were conducted using weighted multivariable logistic regression...

Guillain Barré Syndrome (GBS) is a severe disorder of the peripheral nervous system with an inadequately known etiopathology. It is a post infectious immune mediated disorder, characterized by autoantibody production, complement activation as well as T reactivity against gangliosides. However, the precise etiopathogenesis remains poorly understood in a majority of the patients. Th17 cells, a recently identified lineage of Th cells have emerged as a predominant inducer of autoimmunity and inflammation in various immunological disorders...

Even though tremendous progress has been made in the last decades to elucidate the mechanisms of intestinal homeostasis, dysbiosis and disease, we are only at the beginning of understanding the complexity of the gut ecosystem and the underlying interaction networks. We are also only starting to unravel the mechanisms that pathogens have evolved to overcome the barriers imposed by the microbiota and host to exploit the system to their own benefit. Recent work in these domains clearly indicates that the 'traditional Koch's postulate', which state that a given pathogen leads to a distinct disease, are not valid for all 'infectious' diseases, but that a more complete and complex interpretation of the Koch's postulate is needed in order to understand and explain them...

Peste des petits ruminants (PPR) is a highly infectious disease of small ruminants and caused by small ruminant morbillivirus (SRMV), formerly called peste-des-petits-ruminants virus (PPRV). This disease is circulating in Africa (except most countries in southern Africa), the Arabian Peninsula, the Middle East, and Central, East and South-East Asia. Peste des petits ruminants is still regarded as an exotic disease in China, where its first outbreak was reported in the Ngari region of Tibet in 2007, but effectively controlled by slaughter, vaccination and animal movement restriction in PPR-infected areas...

BACKGROUND: Urinary tract infection (UTI) remains to be one of the most common infectious diseases diagnosed in developing countries. And a widespread use of antibiotics against uropathogens has led to the emergence of antibiotic resistant species. A laboratory based cross-sectional survey was conducted in Shashemene referral hospital to determine the prevalence and antibiotic susceptibility of uropathogens. METHODS: We have collected 384 clean catch mid-stream urine samples from all suspected UTI outpatients using sterile screw capped container...

Chris Lyttleton
Global health security is increasingly reliant on vigilance to provide early warning of transnational health threats. In theory, this approach requires that sentinels, based in communities most affected by new or re-emerging infectious diseases, deliver timely alerts of incipient risk. Medicalizing global safety also implies there are particular forms of insecurity that must be remedied to pre-empt disease spread. I examine vigilance in the context of spreading drug resistant malaria in Southeast Asian border zones and argue that to act as sentinels, marginal groups vulnerable to infection must be able to articulate what social and behavioral factors prompt proliferating disease risks...

Background Genetic alterations cause hereditary diseases (HDs) with a wide range of incidences. Some, like cystic fibrosi, occur frequently (1/1,000 newborns), whilst others, such as Pompe disease and other metabolic disorders are very rare (1/100,000 newborns). They are well under the threshold of 1/3,000, denoted by the European Community as rare diseases (RDs). Genetic alterations are also associated with multifactorial disorders like diabetes, and underline both somatic and germline mutations in cancer...
