Surgical management of contaminated hand wounds may seem anecdotal, but such injuries actually account for an appreciable amount of the activity in emergency hand centers, and recommendations put forward by scientific societies differ. Dealing effectively with this public health issue calls for clarifying the usefulness of the various available treatments. Our study's objective was to determine the effectiveness of surgical debridement. In this prospective study, 92 patients with contaminated hand wounds underwent surgical debridement...

Choosing the best option for reconstructing comminuted joint fractures in hand surgery raises technical challenges due to the small size of the anatomical structures and the required early mobilization. Single-stage reconstructions are clearly preferable, but when the infection risk is high, two-stage alternatives are needed. We report a case of fracture of the head of the 2nd metacarpal resulting from a crocodile bite treated by implanting an articular spacer.

: Unstable distal phalanx fractures are typically treated by pinning of the distal phalanx or the distal interphalangeal joint (DIP). Complications include unstable fixation, K-wire migration, septic arthritis and osteoarthritis. To limit these complications, we wanted to explore the benefits of using locked extra-articular DIP pinning. The cohort consisted of 12 patients (mean age 36.3 years) who had an extra-articular (6 cases) or intra-articular distal phalanx fracture (6 cases). All patients were treated surgically with a construct consisting of two connected K-wires: one was placed inside the shaft of the distal phalanx and the other was placed perpendicular to the middle phalanx...

The mechanisms of persistence and virulence associated to Candida glabrata infections are poorly understood, limiting the ability to fight this fungal pathogen. In this study, the multidrug resistance transporters CgTpo1_1 and CgTpo1_2 are shown to play a role in C. glabrata virulence. The survival of the infection model Galleria mellonella, infected with C. glabrata, was found to increase upon the deletion of either CgTPO1_1 or CgTPO1_2. The underlying mechanisms were further explored. In the case of CgTpo1_1, this phenotype was found to be consistent with the observation that it confers resistance to antimicrobial peptides (AMP), such as the human AMP histatin-5...

BACKGROUND: Simulations using fluorescent tracers can be useful in understanding the spread of pathogens and in devising effective infection control strategies. METHODS: During simulated patient care interactions in which providers wore gloves and gowns, we evaluated environmental and personnel dissemination of fluorescent lotion and bacteriophage MS2 from a contaminated mannequin. The frequency of skin and clothing contamination after removal of personal protective equipment (PPE) was compared before versus after an intervention that included education and practice in PPE donning and doffing...

BACKGROUND: Whilst numerous studies have investigated nurses' compliance with hand hygiene and use of alcohol-based hand rub (ABHR), limited attention has been paid to these issues in allied health staff. Reports have linked infections to breaches in infection control in the radiography unit (RU). With advances in medical imaging, a higher proportion of patients come into contact with RU staff increasing the need for good hand hygiene compliance. This study aimed to evaluate effectiveness on compliance of an intervention to improve awareness of hand hygiene in the RU of a district hospital...

Sparganosis is an important parasitic disease in Guangzhou and is mainly acquired by consumption of frog meat or contact with fresh frogs infected by larval stages (spargana) of the tapeworm species Spirometra mansoni (S. mansoni). In this study we assessed the prevalence of intestinal S. mansoni infections (with adult parasites) in dogs and cats on one hand and of extraintestinal S. mansoni infections (with spargana) in frogs on the other. In Addition, a questinnaire survey among residents in Guangzhou City was carried out in order to evaluate the awareness of autochthonous people about the medical and epidemiological relevance of Spirometra and sparganosis...

Polymyxins have become drugs of last resort for treatment of multi-drug resistant (MDR) Gram-negative infections. However, the mechanisms of resistance to this compound have not been completely elucidated. In this study, we evaluated the mechanisms of resistance to this antimicrobial in two A. baumannii clinical isolates, respectively, susceptible (A027) and resistant (A009) to polymyxin B before and after polymyxin B exposure (A027(ind) and A009(ind)). The pmrAB and lpxACD were sequenced and their transcriptional levels were analyzed by qRT-PCR...

Small animals such as the roundworm C. elegans are excellent models for studying bacterial infection and host response, as well as for genetic and chemical screens. A key methodology is the killing assay, in which the number of surviving animals is tracked as a function of the time post infection. This is a labor-intensive procedure, prone to human error and subjective choices, and often involves undesired perturbation to the animals and their environment. In addition, the survival of animals is just one aspect of a multi-dimensional complex biological process...

Granzyme B (GzmB) is a key cytotoxic molecule utilized by T cells to kill pathogen-infected cells or transformed tumor cells. Previous studies using allogeneic hematopoietic cell transplantation (allo-HCT) murine models showed that GzmB is required for CD8(+) T cells to cause graft-versus-host disease (GVHD). However, our recent study demonstrated that GzmB-mediated damage of CD8(+) T cells diminished their graft-versus-tumor (GVT) activity. In this study, we examined the role of GzmB in GVT effect mediated by conventional CD4(+)CD25(-) T cells (CD4(+) Tcon)...

Infection by Enterovirus A71 (EV-A71) is an important cause of hand, foot, and mouth disease (HFMD). Outbreaks including severe cases with neurological and cardiopulmonary complications have been reported particularly from Southeast Asia. In Europe, the epidemiology of EV-A71 is not well understood. In summer 2015, a two-year-old girl from Thuringia, Germany, presented with rhombencephalitis/brainstem encephalitis associated with severe neurological and cardiopulmonary complications. EV-A71 was detected in stool and almost the entire viral genome was amplified and sequenced...

Hand, foot, and mouth disease (HFMD) is a highly contagious disease that mainly affects infants and children. Enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are the major pathogens of HFMD. Two EV71 vaccines were recently licensed in China and the administration of the EV71 vaccines is believed to significantly reduce the number of HFMD-related severe or fatal cases. However, a monovalent EV71 vaccine cannot cross-protect against CA16 infection, this may result in that it cannot effectively control the overall HFMD epidemic...

Human adenovirus infects terminally differentiated cells and to replicate it must induce S-phase. The chief architects that drive adenovirus-infected cells into S-phase are the E1A proteins, with 5 different isoforms expressed during infection. E1A remodels the infected cell by associating with cellular factors and modulating their activity. The C-terminus of E1A is known to bind to only a handful of proteins. We have identified a novel E1A C-terminus binding protein, Ku70 (XRCC6), which was found to bind directly within the CR4 of E1A from human adenovirus type 5...

Worldwide, Salmonella spp. is a significant cause of disease for both humans and wildlife, with wild birds adapted to urban environments having different opportunities for pathogen exposure, infection, and transmission compared to their natural conspecifics. Food provisioning by people may influence these factors, especially when high-density mixed species flocks aggregate. White Ibises (Eudocimus albus), an iconic Everglades species in decline in Florida, are becoming increasingly common in urbanized areas of south Florida where most are hand-fed...

The clinical impact of enteroviruses associated with hand, foot and mouth disease (HFMD) is unknown outside Asia, and the prevalence of enterovirus A71 (EV-A71) in particular might be underestimated. To investigate the prevalence of enterovirus serotypes and the clinical presentations associated with HFMD in France, we conducted prospective ambulatory clinic-based surveillance of children during April 2014-March 2015. Throat or buccal swabs were collected from children with HFMD and tested for the enterovirus genome...
