Chlorhexidine gluconate (CHG) use helps reduce hospital-acquired infections (HAIs). Chlorhexidine gluconate effectiveness can be reduced by use of skin care products. Although laboratory work can be performed to prove compatibility, such work has limitations. The purpose of this study was to compare HAI rates when CHG antiseptic wipes were used in conjunction with a silicone- and micronutrient-based skin care product line (SMSP) and when CHG wipes were used without the SMSP. Using commercial distribution data, 17 hospitals that purchased both CHG wipes and SMSP were identified...

Marine parasites such as trematodes often compromise the fitness of their hosts. Such effects are generally considered to be density-dependent, i.e. the greater the infection intensity in the host, the greater the detrimental impact on host fitness. However, the mechanisms determining infection in marine hosts are still poorly understood. Here, we investigated the effect of cercarial dose and exposure frequency (single vs. trickle infections) of a marine trematode parasite, Himasthla elongata (Trematoda: Echinostomatidae), on infection intensity and success in its second intermediate host, the blue mussel Mytilus edulis, an abundant and widely distributed bivalve in European coastal waters...

INTRODUCTION: This retrospective study investigated the clinical etiology of community-acquired bacteremic Klebsiellapneumoniae infections, and characterized laboratory and genetic markers which may be associated with primary liver abscess (PLA). METHODS: Community-onset K. pneumoniae bacteremic episodes from 2010 to 2011 were identified from the laboratory information system. Isolates were retrieved for susceptibility testing, hypermucoviscosity testing, PCR-based serotyping (K1, K2 and K5) and PCR detection of virulence genes (rmpA, alls, kfu and aerobactin)...

Mycoplasma pneumoniae (M. pneumoniae) is a major cause of community acquired respiratory infections. And it also causes a number of extrapulmonary manifestations including cardiovascular, dermatological, musculoskeletal, and hematological systems. But, acute hepatitis without lung involvement is rare in adults. Here, we report a case of 32-year-old man who presented with fever, chilling, myalgia, and headache. Biochemical analysis showed severely impaired liver function and leukopenia. Laboratory tests and liver biopsy demonstrated a hepatocellular pattern of M...

Every year Christian pilgrims from around the world visit the holy sites located around the Sea of Galilee. Some become ill during their stay with infectious diseases that were acquired in their country of origin, and are hospitalized at Poriya Medical Center. They pose a diagnostic challenge due to language barriers, the rarity of these infections in Israel, and the fact that diagnostic tests are not readily available. All patient records from 2015 of Holy Land tourists hospitalized at Poriya Medical Center were screened for the diagnosis of imported zoonotic diseases that are not commonly diagnosed in Israel...

BACKGROUND: Retrospective case series suggest that abnormalities in fluid, electrolyte, and acid-base homeostasis may occur among infants with a febrile urinary tract infection. Potentially inaccurate laboratory methods of sodium testing have often been used. METHODS: Between January 2009 and June 2016, we managed 80 previously healthy infants (52 males and 28 females) ≥4 weeks to ≤24 months of age with their first episode of acute pyelonephritis. Ionized sodium, ionized potassium and ionized chloride were determined by direct potentiometry, as recommended by the International Federation of Clinical Chemistry...

Community-acquired pneumonia (CAP) is a common childhood infection and often a reason for inpatient admission, especially when a child is hypoxic or in respiratory distress. Despite advances in technology and diagnostics, it remains difficult to accurately differentiate bacterial CAP from a viral process. Most of the laboratory tests routinely done in inpatient medicine, such as complete blood counts and acute phase reactants, do little to differentiate a viral pneumonia from a bacterial pneumonia. Clinicians must rely heavily on the clinical presentation and decide whether to treat empirically with antibiotics...

BACKGROUND: Hand hygiene practices (HHP), as a critical component of infection prevention/control, were investigated among physiotherapists in an Ebola endemic region. METHOD: A standardized instrument was administered to 44 randomly selected physiotherapists (23 males and 21 females), from three tertiary hospitals in Enugu, Nigeria. Fifteen participants (aged 22-59 years) participated in focus group discussions (FGDs) and comprised 19 participants in a subsequent laboratory study...

The aim of this study was to ascertain farmers' knowledge of the risk of spread of infection from animals to humans, and their transmission prevention practices. This was a survey of farmers who submitted material to Ireland's Regional Veterinary Laboratories in 2015. There was an 84% response rate (1044 farmers). Ninety per cent of farmers were not aware that infection can be acquired from apparently healthy animals. Over half were not aware that disease could be contracted from sick poultry or pets. Conversely, the knowledge of the risk to pregnant women of infection from birthing animals was high (88%)...

Mycoplasma pneumoniae is a frequent cause of community acquired pneumonia, especially in children. Discovered by Eaton in the 1940s, it has long been considered as a virus, in part because of its difficult growth in cultures. M. pneumoniae can cause many complications, some of which are severe such as dermatological lesions or affections of the central nervous system. The laboratory diagnosis of M. pneumoniae is difficult, notably because of the fastidious growth conditions, the persistence of IgM antibody after acute infection and the debated existence of asymptomatic carriers...

REVIEW
Stephen J Aston
Community-acquired pneumonia (CAP) is a common cause of morbidity and mortality in adults worldwide, but its epidemiology varies markedly by region. Whilst in high-income countries, the predominant burden of CAP is in the elderly and those with chronic cardiovascular and pulmonary co-morbidity, CAP patients in low-income settings are often of working age and, in sub-Saharan Africa, frequently HIV-positive. Although region-specific aetiological data are limited, they are sufficient to highlight major trends: in high-burden settings, tuberculosis (TB) is a common cause of acute CAP; Gram-negative pathogens such as Klebsiella pneumoniae are regionally important; and HIV-associated opportunistic infections are common but difficult to diagnose...

BACKGROUND: Among hospital-acquired infections (HAIs) in children, ventilator-associated pneumonia (VAP) is the most common after blood stream infection (BSI). VAP can prolong length of ventilation and hospitalization, increase mortality rate, and directly change a patient's outcome in Pediatric Intensive Care Units (PICU). OBJECTIVES: The research on VAP in children is limited, especially in Iran; therefore, the identification of VAP incidence and mortality rate will be important for both clinical and epidemiological implications...

PURPOSE: Resistant Gram-negative bacterial (GNB) infections, apart from tremendously escalating the cost of treatment, are a cause for substantial morbidity and mortality among hospitalized patients. Such bacteria are rapidly acquiring resistance to many antimicrobial agents, especially the beta-lactams which are the most frequently prescribed antimicrobials in hospital and community patient care settings, and now also to colistin; a last-line drug to treat infections with such bacteria...

BACKGROUND: Cytomegalovirus (CMV) is a common HIV-1 copathogen. Since CMV infection is an important contributor to immune activation, the driving force of HIV disease, an anti-CMV strategy might be beneficial to HIV-infected patients. Shin et al. (J Acquir Immune Defic Syndr 2014; 65:251-258) reported that anti-CMV therapy with valganciclovir in coinfected individuals results in a decrease of HIV viral load that is not accompanied by a decrease of immune activation. This suggests an alternative mechanism for HIV inhibition other than suppression of CMV-mediated inflammation...

To investigate the trends of antimicrobial resistance in pathogens isolated from skin and soft-tissue infections (SSTI) at dermatology departments in Japan, a Japanese surveillance committee conducted the first nationwide survey in 2013. Three main organisms were collected from SSTI at 30 dermatology departments in medical centers and 10 dermatology clinics. A total of 860 strains - 579 of Staphylococcus aureus, 240 of coagulase-negative Staphylococci, and 41 of Streptococcus pyogenes - were collected and shipped to a central laboratory for antimicrobial susceptibility testing...

Bacterial biofilms form when bacteria adhere to a surface and produce an exopolysaccharide matrix ( Costerton Science 1999 , 284 , 1318 ; Davies Science 1998 , 280 , 295 ; Flemming Nat. Rev. Microbiol. 2010 , 8 , 623 ). Because biofilms are resistant to antibiotics, they are problematic in many aspects of human health and welfare, causing, for instance, persistent fouling of medical implants such as catheters and artificial joints ( Brunetto Chimia 2008 , 62 , 249 ). They are responsible for chronic infections in the lungs of cystic fibrosis patients and in open wounds, such as those associated with burns and diabetes...

We describe an 8-year-old boy with acquired hemophilia A (AHA) associated with streptococcal infection and amoxicillin. Laboratory data revealed low factor VIII activity (FVIII:C, 1.5 IU/dl), and FVIII inhibitor (15.9 BU/ml). Comprehensive coagulation function assays, including rotation thromboelastometry (ROTEM(®)), revealed a markedly prolonged clotting time. Thrombin and plasmin generation (TG/PG) appeared to be moderately impaired. The inhibitor epitope of his anti-FVIII autoantibody recognized light and heavy chains...
