The rate of saturated-to-unsaturated FA conversion increased as the concentration of vancomycin in the growth media was increased. Therefore, it is concluded that S. aureus tend to modify their membrane lipid chemistry from saturated to unsaturated in order to survive in a vancomycin stress environment.”
“Purpose of review
To present the latest findings regarding interstitial lung disease (ILD) in idiopathic inflammatory myopathies, focusing on the phenotype of ILD and auto-antibodies, pathogenesis and treatment.
Recent findings
Interstitial lung disease is a common manifestation of myositis
and different phenotypes of ILD associate with various clinical or serological phenotypes. Thus, antisynthetase antibodies are strongly associated with ILD, especially for non-Jo-1 (anti-PL-7 and anti-PL-12) where the association
approaches 90-100%. A rare form of ILD with a very poor prognosis, AZD1152 nmr acute and rapidly progressive lung disease, is strongly associated with clinically amyopathic dermatomyositis (CADM) and a novel – anti-CADM-140 auto-antibody. A combination of anti-Jo-1 and anti-SSA/Ro antibodies is another marker of severe pulmonary involvement. The use of immunossuppresive therapy in myositis-associated ILD is based on clinical experience, and a few new case reports indicate beneficial effect of tacrolimus in antisynthetase syndrome and rituximab in resistant or acute forms of lung disease but further studies are needed.
Summary
Interstitial Baf-A1 lung disease is a common manifestation of myositis.
Auto-antibody profile seems to determine the frequency, course and severity of lung disease. New biological therapies such as rituximab show promising results in resistant and acute lung disease but controlled trials are needed.”
“In Japan, beta-lactamase-nonproducing, ampicillin-resistant organisms have been evident among Haemophilus influenzae type b (Hib) isolates since 2000, when no appropriate vaccine had been approved. We therefore performed molecular analysis of agents causing H. influenzae BYL719 meningitis nationwide over the following 10 years. Some 285 institutions have participated in surveillance since 2000. The capsular type and resistance genes of 1,353 isolates and 23 cerebrospinal fluid samples from pediatric patients with meningitis we had received from 2000 to 2011 were analyzed by polymerase chain reaction. Blood and spinal fluid test results obtained when patients were admitted were examined for correlation with outcomes. Hib was found in 98.9 % of isolates. We received more than 100 Hib isolates per year until vaccination began in December 2008, when these isolates decreased, especially since establishment of a special fund to promote vaccination in November 2010. Decreased incidence among infants 7 months to 2 years old has been particularly notable.
