This study indicates that H. pylori was found in increased prevalence in the nasal polyps. However, further controlled epidemiologic studies would be necessary to confirm our results and clarify the potential underlying pathogenetic mechanisms.
In the light of these findings, it might be concluded that topical local anesthetic ointments in routine settings may have a preventive role against some bacteria.
Infection with Helicobacter pylori (H. pylori) strains secreting cytotoxin-associated gene A (CagA) and vacuolating cytotoxin A (VacA) proteins is associated with more severe gastroduodenal pathologies. However, this association varies among geographical regions and ethnic groups. We investigated the frequencies of antibodies to CagA and VacA proteins in 131 H. pylori-infected dyspeptic patients [40 duodenal ulcer (DU), 19 gastric ulcer (GU), 28 gastric cancer (GC), and 44 non-ulcer dyspepsia (NUD)] across 30 H. pylori-infected and endoscopically normal asymptomatic subjects (AS). Anti-CagA and anti-VacA antibodies were detected by Western blotting. The positivity rates of anti-CagA and anti-VacA antibodies were higher in patients with DU (92.5 and 75%), GU (89.5 and 84.2%) and GC (96.4 and 85.7%) than patients with NUD (70.5 and 50%) and AS (50 and 23.3%) (p < 0.05). CagA+ VacA+ phenotype was more frequent in patients with DU, GU and GC than patients with NUD and AS (75, 84.2, 85.7 vs. 47.7 and 20%, respectively) (p < 0.01). Our results showed that there is a significantly positive association between the presence of anti-CagA and anti-VacA antibodies and DU, GU and GC in our region.
Listeria monocytogenes is an uncommon cause of bacterial meningitis beyond the neonatal period. Patients with immunosuppression or neoplastic disease are at increased risk of developing serious invasive disease, particularly meningitis. L. monocytogenes meningitis in two previously healthy, immunocompetent children aged 7 years and 18 months is described. One of them was successfully treated with ampicillin and amikacin. In the other there was resistance to ampicillin, and meropenem, vancomycin and amikacin were given. One patient developed unilateral abducens paralysis and inappropriate antidiuretic hormone secretion. L. monocytogenes should be suspected in children with bacterial meningitis who fail to respond to empirical antibiotic therapy.
Objective: We aimed to retrospectively determine the distribution of antibiotic resistance rates of P. aeruginosa strains which were isolated from samples sent to our hospital's microbiology laboratory between the years 2011-2015. Methods: Various samples sent from different clinics to our laboratory for the isolation of P. aeruginosa were inoculated on blood agar and EMB agar plates and incubated at 37° C for 18-24 hours. Grown bacteria were identified by conventional techniques and MALDI Biotyper (Bruker, Germany) system. Antimicrobial susceptibility testing of isolates for the years 2011-2014 were studied in accordance to recommendations of Clinical Laboratory Standards Institute (CLSI) and for the year of 2015 according to The European Committee on Antimicrobial Susceptibility Testing (EUCAST) recommendations. Antimicrobial susceptibilities were evaluated by the disk diffusion method with Mueller-Hinton medium in outpatients and by Phoenix automated system (BD, Sparks, MD, USA) in service and intensive care patients. Results: P. aeruginosa strains isolated from 1026 outpatients and 408 inpatients between the years ÖZET Amaç: Hastanemiz mikrobiyoloji laboratuvarına gönderilen örneklerden izole edilen P. aeruginosa suşlarının 2011-2015 yıllarındaki antibiyotik direnç yüzdelerinin dağılımının saptanması amaçlanmıştır.
BackgroundThis is the first report of breast abscess due to Salmonella enterica serotype Typhimurium. Staphylococcus aureus is known as the most common cause of breast abscess. Salmonella spp. may occasionally form localized abscesses after dissemination to various organ systems following a bacteraemia. But breast abscess related to Salmonella spp is a very rare complication.Case presentationA 43-year-old female patient referred to our hospital with a lump, fever and mild pain in her breast. The patient was not pregnant or lactating at that time. She had a history of rheumatoid arthritis for 5 years and was under immunosuppressive therapy. Ultrasonography of the breast revealed an abscess. The abscess was drained and sent for culture to medical microbiology laboratory. The microorganism was identified as Salmonella enterica serotype Typhimurium and found to be sensitive to all antibiotics tested. The patient was cured after surgical debridement and antibiotic therapy. The abscess did not recur again.ConclusionsThis case is presented to draw attention to non-typhoidal Salmonella as rare causes of breast abscess and submission of specimens to the microbiology laboratory for accurate diagnosis and treatment especially in patients with underlying immunosuppressive diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
