Effects of a Primary Care Antimicrobial Stewardship Program on Meticillin-Resistant Staphylococcus aureus Strains across a Region of Catalunya (Spain) over 5 Years.

Primary care antimicrobial stewardship program (ASP) interventions can reduce the over-prescription of unnecessary antibiotics, but the impact on the reduction in bacterial resistance is less known, and there is a lack of available data. We implemented a prolonged educational counseling ASP in a large regional outpatient setting to assess its feasibility and effectiveness. Over a 5-year post-implementation period, which was compared to a pre-intervention period, a significant reduction in antibiotic prescriptions occurred, particularly those associated with greater harmful effects and resistance selection. There was also a decrease in methicillin-resistant Staphylococcus aureus (MRSA) strains and in their co-resistance to other antibiotics, particularly those with an ecological impact.

Submucosal fat accumulation in Crohn's disease: evaluation with sonography.

BACKGROUND/AIMS: The study objective is to investigate the ultrasound features that allow suspecting the presence of submucosal fat deposition, called the fat halo sign (FHS), in the intestinal wall of patients with Crohn's disease. METHODS: Computed tomography (CT) examinations over a period of 10 years were reviewed for the presence of the FHS in the bowel wall. A measurement of less than -10 Hounsfield units was regarded as indicative of fat. We included only patients who had undergone ultrasound examinations 3 months before or after CT. The study cohort group comprised 68 patients. Wall and submucosal thickness were measured on longitudinal ultrasound sections. A receiver operating characteristic curve was constructed to determine the best cutoff of ultrasound submucosal wall thickness value for predicting FHS in the bowel wall determined on CT. RESULTS: The FHS was present in 22 patients (31%) on CT. There were significant differences between submucosal thickness of patients with FHS and patients without FHS (4.19 mm vs. 2.41 mm). From the receiver operating characteristic curve, a threshold value of 3.1 mm of submucosal thickness had the best sensitivity and specificity to suspect FHS (95.5% and 89.1%, respectively; area under the curve, 0.962), with an odds ratio of 172. All of 16 patients with a submucosal thickness >3.9 mm had FHS. CONCLUSIONS: FHS in patients with Crohn's disease can be suspected on ultrasound in cases with marked thickening of the submucosa layer. In these cases, the activity of the disease should be measured by other parameters such as the color Doppler.

Impact of a Primary Care Antimicrobial Stewardship Program on Bacterial Resistance Control and Ecological Imprint in Urinary Tract Infections.

Antimicrobial stewardship programs (ASPs) are a central component in reducing the overprescription of unnecessary antibiotics, with multiple studies showing benefits in the reduction of bacterial resistance. Less commonly, ASPs have been performed in outpatient settings, but there is a lack of available data in these settings. We implemented an ASP in a large regional outpatient setting to assess its feasibility and effectiveness. Over a 5-year post-implementation period, compared to the pre-intervention period, a significant reduction in antibiotic prescription occurred, with a reduction in resistance in E. coli urinary isolates. ASP activities also were found to be cost-effective, with a reduction in medication prescription.

Microarray analysis of human keratinocytes from different anatomic sites reveals site-specific immune signaling and responses to human papillomavirus type 16 transfection.

BACKGROUND: Stratified human keratinocytes (SHKs) are an essential part of mucosal innate immune response that modulates adaptive immunity to microbes encountered in the environment. The importance of these SHKs in mucosal integrity and development has been well characterized, however their regulatory immunologic role at different mucosal sites, has not. In this study we compared the immune gene expression of SHKs from five different anatomical sites before and after HPV16 transfection using microarray analyses. METHODS: Individual pools of human keratinocytes from foreskin, cervix, vagina, gingiva, and tonsils (HFKs, HCKs, HVKs, HGKs and HTLKs) were prepared. Organotypic (raft) cultures were established for both normal and HPV16 immortalized HFKs, HCKs, HVKs, HGKs and HTLKs lines which stably maintained episomal HPV16 DNA. Microarray analysis was carried out using the HumanHT-12 V4 gene chip (Illumina). Immune gene expression profiles were obtained by global gene chip (GeneSifter) and Ingenuity pathway analysis (IPA) for each individual site, with or without HPV16 transfection. RESULTS: We examined site specific innate immune response gene expression in SHKs from all five different anatomical sites before and after HPV16 transfection. We observed marked differences in SHK immune gene repertoires within and between mucosal tracts before HPV 16 infection. In addition, we observed additional changes in SHKs immune gene repertoire patterns when these SHKs were productively transfected with HPV16. Some immune response genes were similarly expressed by SHKs from different sites. However, there was also variable expression of non-immune response genes, such as keratin genes, by the different SHKs. CONCLUSIONS: Our results suggest that keratinocytes from different anatomical sites are likely hard wired in their innate immune responses, and that these immune responses are unique depending on the anatomical site from which the SHKs were derived. These observations may help explain why select HPV types predominate at different mucosal sites, cause persistent infection at these sites, and on occasion, lead to HPV induced malignant and benign tumor development.

Sindrome de las tuberías oxidadas: reporte de caso / Rusty-Pipe Syndrome: case report

La telorragia bilateral o secreción sanguinolenta a través del pezón es un signo alarmante, pero durante el embarazo y la lactancia puede ser totalmente benigna. Es necesario un diagnóstico diferencial cuidadoso y evitar las intervenciones quirúrgicas, a menos que se descubra una causa subyacente de la misma. Este cuadro clínico es conocido como síndrome de las tuberías oxidadas o Rusty-Pipe syndrome. Se presenta el caso de una primigesta de 30 años que presentó telorragia bilateral tras un parto eutócico a las 40 semanas, en el Hospital Dr. Peset de Valencia, España.

Bilateral thelorrhagia or bloody discharge from the nipple is an alarm symptom, but it can be benign during pregnancy and breastfeeding. A careful differential diagnosis is required and surgical interventions should be avoided unless an underlying cause is discovered. This clinical condition is known as rusty-pipe syndrome. We report the case of a 30-year-old primiparous woman who presented with bilateral thelorrhagia after eutocic delivery at 40 weeks in the Dr. Peset Hospital, Valencia (Spain).

Principles and methodology for translation and cross-cultural adaptation of the Nordic Occupational Skin Questionnaire (NOSQ-2002) to Spanish and Catalan.

BACKGROUND: Occupational skin diseases are among the most frequent work-related diseases in industrialized countries. The Nordic Occupational Skin Questionnaire (NOSQ-2002), developed in English, is a useful tool for screening of occupational skin diseases. OBJECTIVES: To culturally adapt the NOSQ-2002 to Spanish and Catalan and to assess the clarity, comprehension, cultural relevance and appropriateness of the translated versions. METHODS: The International Society for Pharmacoeconomics and Outcomes Research (ISPOR) principles of good practice for the translation and cultural adaptation of patient-reported outcomes were followed. RESULTS: After translation into the target language, a first consensus version of the questionnaire was evaluated in multiple cognitive debriefing interviews. The expert panel introduced some modifications in 39 (68%) and 27 (47%) items in the Spanish and Catalan version, respectively (e.g. addition of examples and definitions, reformulation of instructions and use of direct question format). This version was back translated and submitted to the original authors, who suggested a further seven and two modifications in the Spanish and Catalan versions, respectively. A second set of cognitive interviews were performed. A consensus version of both questionnaires was obtained after final modifications based on comments by the patients. CONCLUSIONS: The final versions of the Spanish and Catalan NOSQ-2002 questionnaires are now available at www.NRCWE.dk/NOSQ.
