The impact on patient outcome and the inappropriate use of antibiotics deserves further investigation.”
“Leishmaniasis is endemic in the Mediterranean region, and the prevalence of latent infection in this area is high. Treatment with tumour necrosis factor (TNF) antagonists represents a major breakthrough in the treatment of several inflammatory diseases, including psoriasis. Reports describing opportunistic leishmaniasis in European patients treated with TNF-alpha antagonist drugs are rapidly accumulating. learn more We describe a case of cutaneous leishmaniasis in a patient treated with infliximab and corticosteroids.”
“We report a case illustrating the potential use of 18F-fluorodeoxyglucose positron emission tomography

combined with computed tomography (PET/CT) for the diagnosis of infective endocarditis (IE) in an 84-y-old

woman who had a history of chronic left knee osteitis and a mitral cardiac valve bioprosthesis replacement and a pacemaker. She developed a polymicrobial knee FAK inhibitor infection 15 days after her total knee replacement. Transoesophageal echocardiography showed a new mitral regurgitation, but no vegetation or abscess. PET/CT showed hypermetabolic hyperactivity around the mitral cardiac valve prosthesis and the intracardiac pacemaker leads. We found 17 case reports and 2 case series of IE in which PET/CT showed encouraging results for the detection of IE. PET/CT may be used in patients with a suspicion Ribonucleotide reductase of IE who do not have echocardiographic evidence of IE. It may also be useful for identifying the portal of entry

of an infection and for identifying secondary foci (mycotic aneurysm).”
“For years, scientists from various disciplines have studied the effects of endocrine disrupting chemicals (EDCs) on the health and wellbeing of humans and wildlife. Some studies have specifically focused on the effects of low doses, i.e. those in the range that are thought to be safe for humans and/or animals. Others have focused on the existence of non-monotonic dose response curves. These concepts challenge the way that chemical risk assessment is performed for EDCs. Continued discussions have clarified exactly what controversies and challenges remain. We address several of these issues, including why the study and regulation of EDCs should incorporate endocrine principles; what level of consensus there is for low dose effects; challenges to our understanding of non-monotonicity; and whether EDCs have been demonstrated to produce adverse effects. This discussion should result in a better understanding of these issues, and allow for additional dialog on their impact on risk assessment. (c) 2013 Elsevier Inc. All rights reserved.”
“Given the increasing use of Wistar Han (WH) rats in regulatory toxicology studies, these studies were performed to characterize the onset of sexual maturation in maturing WH rats as compared to Sprague-Dawley (SD) rats.
