Establishment of quantitative PCR (qPCR) and culture laboratory facilities in a field hospital in benin: 1-year results.

No simple diagnostic tool is available to confirm Mycobacterium ulcerans infection, which is an emerging disease reported in many rural areas of Africa. Here, we report the 1-year results of a hospital laboratory that was created in an area of endemicity of Benin to facilitate the diagnosis of M. ulcerans infection.

Connecting the dots: could microbial translocation explain commonly reported symptoms in HIV disease?

Microbial translocation within the context of HIV disease has been described as one of the contributing causes of inflammation and disease progression in HIV infection. HIV-associated symptoms have been related to inflammatory markers and sCD14, a surrogate marker for microbial translocation, suggesting a plausible link between microbial translocation and symptom burden in HIV disease. Similar pathophysiological responses and symptoms have been reported in inflammatory bowel disease.

[Splenic cysts as an incidental finding--what's next?].

History And Admission Findings: A 55-year-old woman presented comfortable and well-nourished for a check up. The physical examination remained without pathological results. However lipase parameter in serum was conspicuously elevated we performed an ultrasound examination.

Worldwide emergence of colistin resistance in Klebsiella pneumoniae from healthy humans and patients in Lao PDR, Thailand, Israel, Nigeria and France owing to inactivation of the PhoP/PhoQ regulator mgrB: an epidemiological and molecular study.

The emergence of colistin-resistant Klebsiella pneumoniae (CRKP) is a major public health concern worldwide. In this study, the prevalence and molecular basis of colistin resistance in CRKP isolated from healthy individuals and patients in Lao PDR, Thailand, Nigeria and France were investigated. Stool samples were screened by culture for the presence of colistin-resistant Klebsiella spp.

Acinetobacter gandensis sp. nov. isolated from horse and cattle.

We previously reported the presence of an OXA-23 carbapenemase in an undescribed species of the genus Acinetobacter isolated from horse dung at the Faculty of Veterinary Medicine, Ghent University, Belgium. Here we include six strains to corroborate the delineation of this taxon by phenotypic characterization, DNA-DNA hybridization, 16S rRNA gene and rpoB sequence analysis, % G+C determination, MALDI-TOF MS and fatty acid analysis. The nearly complete 16S rRNA gene sequence of strain UG 60467(T) showed the highest similarities with those of the type strains of Acinetobacter bouvetii (98.

Prevalence and incidence of early childhood caries among African-American children in Alabama.

Objectives: This study aims to assess the prevalence and incidence of early childhood caries (ECC) in African-American children.

Methods: A cohort of 96 African-American children approximately 1 year of age at baseline were recruited in Uniontown, Alabama, and followed for 3 years. Oral examinations were conducted annually by one of three trained/calibrated dentists using portable equipment, without radiographs, following WHO criteria.

The impact of performing bacterial identification and antimicrobial susceptibility testing on bronchoalveolar fluid cultures 24 h a day in a microbiology laboratory.

We previously demonstrated the positive impact of performing bacterial identification and antimicrobial susceptibility testing (AST) after day hours (night service [NS]) for certain clinical samples on the treatment of infected patients. Our objective was to evaluate the impact of including positive bronchoalveolar lavage (BAL) cultures in our NS. Two major positive consequences were recorded: initiation of earlier appropriate treatment and earlier change to a reduced-spectrum but still effective regimen.

Clinical epidemiology of laboratory-confirmed Buruli ulcer in Benin: a cohort study.

Background: Buruli ulcer, caused by Mycobacterium ulcerans, was identified as a neglected emerging infectious disease by WHO in 1998. Although Buruli ulcer is the third most common mycobacterial disease worldwide, understanding of the disease is incomplete. We analysed a large cohort of laboratory-confirmed cases of Buruli ulcer from Pobè, Benin, to provide a comprehensive description of the clinical presentation of the disease, its variation with age and sex, and its effect on the occurrence of permanent functional sequelae.

Development and characterization of a novel, antimicrobial, sterile hydrogel dressing for burn wounds: single-step production with gamma irradiation creates silver nanoparticles and radical polymerization.

Patients with burn wounds are susceptible to wound infection and sepsis. This research introduces a novel burn wound dressing that contains silver nanoparticles (SNPs) to treat infection in a 2-acrylamido-2-methylpropane sulfonic acid sodium salt (AMPS-Na(+) ) hydrogel. Silver nitrate was dissolved in AMPS-Na(+) solution and then exposed to gamma irradiation to form SNP-infused hydrogels.

Gender Norms and Family Planning Practices Among Men in Western Jamaica.

The objective of this study was to identify the association between gender norms and family planning practices among men in Western Jamaica. A cross-sectional survey of 549 men aged 19 to 54 years attending or visiting four government-operated hospitals was conducted in 2011. Logistic regression models were used to identify factors associated with taking steps to prevent unwanted pregnancy, intention to have a large family size (three or more children), and fathering children with multiple women.

Evaluation of 16S rRNA gene PCR sensitivity and specificity for diagnosis of prosthetic joint infection: a prospective multicenter cross-sectional study.

There is no standard method for the diagnosis of prosthetic joint infection (PJI). The contribution of 16S rRNA gene PCR sequencing on a routine basis remains to be defined. We performed a prospective multicenter study to assess the contributions of 16S rRNA gene assays in PJI diagnosis.

First report of endocarditis caused by a Pseudoclavibacter species.

We describe the first case of Pseudoclavibacter species endocarditis in a 44-year-old patient. This genus, rarely isolated from humans, confirms here its role as a human pathogen.

Assessment of high-risk human papillomavirus infections using clinician- and self-collected cervical sampling methods in rural women from far western Nepal.

Introduction: Nepal has one of the highest cervical cancer rates in South Asia. Only a few studies in populations from urban areas have investigated type specific distribution of human papillomavirus (HPV) in Nepali women. Data on high-risk HPV (HR-HPV) types are not currently available for rural populations in Nepal.

A case of guilt by association: Water bug bite incriminated in M. ulcerans infection.

Buruli ulcer is a cutaneous mycobacterial disease caused by Mycobacterium ulcerans, whose incidence is increasing steadily, especially in West Africa. This study reports a first documented case of M. ulcerans infection which can be attributed to a water bug bite at the site of the primary lesion.

Cytotoxicity testing of silver-containing burn treatments using primary and immortal skin cells.

A novel burn wound hydrogel dressing has been previously developed which is composed of 2-acrylamido-2-methylpropane sulfonic acid sodium salt with silver nanoparticles (silver AMPS). This study compared the cytotoxicity of this dressing to the commercially available silver products; Acticoat™, PolyMem Silver(®) and Flamazine™ cream. Human keratinocytes (HaCaT and primary HEK) and normal human fibroblasts (NHF) were exposed to dressings incubated on Nunc™ polycarbonate inserts for 24, 48 and 72h.

Perceptions of barriers and facilitators to cervical cancer screening among low-income, HIV-infected women from an integrated HIV clinic.

Significantly elevated rates of cervical cancer and low rates of Papanicolaou (Pap) smear screening have been documented among HIV-infected women. However, little is known about women's perceptions of cervical cancer screening utilization. Hence, this study describes barriers and facilitators related to cervical cancer screening in a sample of HIV-infected women seeking care at an integrated HIV clinic in Houston, Texas.
