Non-touch treatment to solve the persistent contamination of culture plates with Aspergillus niger in a clinical microbiology laboratory of Spain.

A pseudo-outbreak of Aspergillus caused by false positive cultures can have a high sanitary impact. We determined the effectiveness (fungal load elimination) of a non-touch disinfection system, vs conventional disinfection methods, to solve steady contamination of culture plates with Aspergillus niger at a clinical microbiology laboratory. Routine cleaning-disinfection (RCD), intensive cleaning-disinfection (ICD), and terminal airborne disinfection (TAD) were employed in stages. Air sampling was carried out before and after each procedure. The effectiveness of TAD on contact surfaces was tested by surface sampling. After RCD, ICD, and TAD, there was a mean decrease of 5.4 (95% CI = 1.8-9.0), 19.2 (95% CI = 12.4-26.0), and 4.4 (95% CI = 2.5-6.3) CFU per tested area, and 46.2%, 21.7%, and 95.5% of contaminated areas became sterile, respectively. There was a mean decrease of 30.6 CFU per tested surface (p < 0.0007) and 50% of tested surfaces became sterile. Global effectiveness of RCD, ICD, and TAD was 68.8% (95% CI = 68.5-69.1), 82.2% (95% CI = 82.1-82.3), and 99.0% (95% CI = 98.8-99.2), respectively. The effectiveness was higher with TAD (4.1 CFU/cm2 less than with ICD; p = 0.0290). No further contamination has occurred since then. When construction and renovation activities are discarded and RCD and ICD practices are insufficient, non-touch disinfection remove residual dust contamination and avoid recurrence.

Anthropometric assessment of schoolchildren from the La Mancha-Centro health area. Comparison with the Spanish Cross-Sectional Growth Study 2010.

OBJECTIVES: To determine weight, height and body mass index (BMI) of schoolchildren from the La Mancha-Centro health area and compare them with those determined by the Spanish Cross-sectional Growth Study 2010 (SCGS-2010). METHODS: Cross-sectional study of 954 schoolchildren aged 6-12 years. Mean, standard deviation, and percentile distributions of weight, height, and BMI by gender and age were obtained. Differences in each 6-month age group were analyzed. RESULTS: There was a progressive increase in BMI with age, which was significant in girls from nine years of age on and in boys from 8.5 years on. From age 10, average BMI was 2.3 kg/m2 higher than at younger ages (p < 0.001). The biggest difference between genders occurred at age 12: 2 ± 0.98 kg/m2 higher in boys (p = 0.042). Overall, no significant differences were found in weight, height and BMI vs. SCGS-2010, although mean weight of male children from La Mancha-Centro aged between 8.5 and 11.5 years was 3.9 kg higher than that of the rest of Spanish male children. CONCLUSIONS: Anthropometric parameters of schoolchildren from La Mancha-Centro do not significantly differ from national standards; however, preadolescent males from La Mancha-Centro weigh almost 4 kg more.

Feasibility and efficacy of the Vojta therapy in subacromial impingement syndrome: a randomized controlled trial.

Subacromial impingement syndrome (IS) is a common disorder associated with functional impairment and disability of the shoulder. The aim of this study was to evaluate the efficacy of Vojta therapy (VT) techniques compared with standard therapy (ST) in patients with subacromial IS. A randomized controlled trial was performed, with 60 patients with IS (mean age, 61±12 years) randomized into two groups: ST (n=30) and ST plus Vojta therapy (SVT, n=30). Both received 15 treatment sessions over 4 weeks. Outcome measures included pain intensity, functionality, joint range of motion (RoM), strength, and quality of life measurements. The efficacy of both treatments was analysed, both comparatively and separately, immediately after completion of treatment and after 3 months. After the intervention, both groups showed statistically significant differences in visual analogue scale (P=0.001), RoM (P<0.01), and strength (P<0.001), which were also seen 3 months after the intervention. SVT is more efficient in both the short and medium term in reducing pain, improving functionality, increasing articular RoM and strength, and offering a better quality of life in IS patients.

[Carbapenamase OXA-23 like-producing Acinetobacter baumanii epidemic outbreak in a hospitalization unit.] / Brote epidémico por Acinetobacter baumanii productor de carbapenamasa OXA-23 like en una unidad de hospitalización.

OBJECTIVE: Despite its great ubiquity and morbidity and mortality, the scientific evidence on the hospital control of multiresistant Acinetobacter baumanii (ABMR) outside the Intensive Care Units in Spain is scarce. The objective was to describe an epidemic outbreak by MRAB and analyze the effectiveness of the actions carried out. METHODS: Prospective observational study of admitted-rotated patients in a multipathological control at the University Hospital of Guadalajara, Spain, during the outbreak (September 20-November 3, 2017); using Mambrino Electronic Health Record. A genetic study of the resistance mechanism and molecular characterization of the strains were carried out. Frequency measurements were estimated, with subsequent comparative analysis of cases vs controls. RESULTS: The median age of the study population (N=138) was 83.2 years (Interquartile Range [IR]=69.7-90.1). There were 3 cases of ABMR infection among them. Thirteen percent required issolation, 17% because of MRAB. The MRAB incidence was 2.2 cases/100 admitted-rotated (mortality rate=33%). The excess stay for cases was 17±4.3 (95%CI=8.5-25.6), with an incidence density of 3 cases/103 days. The responsible strain was carbapenemase OXA-23. We found a single case in the colonization study of contacts. No MRAB was isolated from environmental samples. CONCLUSIONS: Along with epidemiological research, coordination and compliance with precautions; prompt identification and management of an outbreak are crucial to minimize the colonization pressure and to stop dissemination.

OBJETIVO: Pese a su gran ubicuidad y morbimortalidad, la evidencia científica sobre el control hospitalario de Acinetobacter baumanii multirresistente (ABMR) fuera de las Unidades de Cuidados Intensivos en España es escasa. El objetivo fue describir un brote epidémico por ABMR y analizar la efectividad del manejo. METODOS: Se realizó un estudio observacional retrospectivo de los ingresados-rotados (N=138) en un control de pluripatológicos del Hospital Universitario de Guadalajara (España), durante el brote (20 septiembre-3 noviembre de 2017), utilizando la Historia Clínica Electrónica Mambrino. Se realizó un estudio genético del mecanismo de resistencia y caracterización molecular de cepas. Se estimaron medidas de frecuencia y análisis comparativo de casos respecto a controles. RESULTADOS: La mediana de edad de la población expuesta fue de 83,2 años (Rango Intercuartílico [RI]=69,7-90,1). Hubo entre ellos tres casos de infección por ABMR. Requirieron aislamiento un 13% de los ingresados-rotados, el 17% por ABMR. La incidencia de ABMR fue de 2,2 por cada 100 ingresados-rotados (tasa de mortalidad=33%). El exceso de estancia de los casos fue de 17±4,3 días (IC95%=8,5-25,6), con una densidad de incidencia de 3/103 días. La cepa responsable fue carbapenemasa OXA-23. En el estudio de colonización de contactos se evidenció un caso. El estudio ambiental resultó negativo. CONCLUSIONES: Junto a la investigación epidemiológica, la coordinación y el cumplimiento de precauciones, la prontitud en la identificación y gestión del brote son determinantes para minimizar la presión de colonización y frenar la cadena de diseminación.

Vacunación sublingual con bacterias inactivadas en pacientes nefrológicos con infección urinaria recurrente: experiencia en un centro de España / Sublingual vaccination with inactivated bacteria in recurrent urinary tract infection of nephrologic patients: experience in a center in Spain

Resumen Introducción: las infecciones del tracto urinario (ITU) son frecuentes en pacientes con enfermedad renal crónica (ERC). Una opción de tratamiento cuando estas infecciones son recurrentes es la vacunación bacteriana sublingual. Objetivo: determinar la respuesta a la vacunación bacteriana sublingual en pacientes nefrológicos con ITU recurrente. Materiales y métodos: estudio cuasi experimental en el que se evaluó la evolución en 15 meses de los pacientes con ITU recurrente que asistieron a consulta externa de nefrología. Tras recibir tratamiento antibiótico según antibiograma para cada ITU, los participantes tomaron un ciclo de la vacuna sublingual bacteriana Uromune® durante tres meses. Se recogieron datos sociodemográficos y sobre factores de riesgo asociados, análisis de sangre y orina, episodios de ITU en los seis meses previos y posteriores, microorganismos causantes, tratamiento antibiótico concomitante, respuesta al tratamiento y resolución de la ITU. Resultados: se incluyeron 26 pacientes (80,8 % mujeres) con una media de edad de 61,9±18,4 años, de los cuales el 46,2 % tenía diabetes y el 47,7 %, afectación de la función renal. La media de ITU fue 3,62±1,77 (rango: 1 -7) antes de la vacuna y de 1,69±1,77 (rango: 0-5) después. Se recogieron 184 urocultivos: 74,9 % positivos, 16,9 % negativos y 8,2 % contaminados. Las bacterias más frecuentes fueron Escherichia coli (55,4 %), Enterococcus faecalis (6 %) y Enterobacter cloacae (2,7 %). El 50 % de los participan- tes presentó síndrome miccional, que se asoció inversamente con la edad (p<0,05). El 26,9 % no volvió a tener ITU y el 73,1 % tuvo menos episodios. Los pacientes con ERC avanzada (estadios IV-V) respondieron peor a la vacuna (92,9 % vs 50 %, p=0,025). Conclusiones: la vacunación bacteriana sublingual es una buena opción de tratamiento para la ITU recurrente de pacientes con ERC, siendo más eficaz en los que presentan mejor función renal.

Abstract Introduction: Urinary tract infections (UTIs) are common in patients with chronic kidney disease. A treatment option in recurrent UTI is sublingual bacterial vaccination. The objective of this study was to determine the response to vaccination in nephrologic patients with recurrent UTI. Method: Quasi-experimental study before-after (15 months) in patients with recurrent UTI from the outpatient nephrology consultation. After receiving antibiotic treatment for each UTI, patients took one cycle of the sublingual bacterial vaccine Uromune? for three months. Sociodemographic data, associated risk factors, analysis, UTI in the previous and subsequent six months, microorganisms, concomitant antibiotic treatment, response to treatment and resolution of UTI were collected. Results: Twenty-six patients (80.8% female) of 61.9 ±18.4 years, 46.2% with diabetes and 47.7% with impaired renal function were included. The episodes of UTI were 3.62 ±1.77 (1-7) before and 1.69 ± 1.77 (0-5) after vaccination. In total, 184 urine cultures were collected: 74.9% positive, 16.9% negative and 8.2% contaminated. The most frequent bacteria were Escherichia coli (55.4%), Enterococcus faecalis (6%) and Enterobacter cloacae (2.7%). Fifty percent had voiding syndrome, which was inversely associated with age (p < 0.05); 26.9% did not have a UTI again and 73.1% had fewer episodes. Patients with advanced chronic disease (stages 4-5) reponded worse to the vaccine (92.9% vs 50%, p =0.025). Conclusions: Sublingual bacterial vaccination is a good treatment option in recurrent UTI of nephrologic patients, being more effective in those with better renal function.

Temporada de gripe y VRS 2018-19 y efectividad vacunal frente a la necesidad de atención hospitalaria por gripe en la provincia de Guadalajara / Flu and VRS 2018-19 Season and vaccine effectiveness against the need for hospital flu treatment in Guadalajara province, Spain

INTRODUCCIÓN: El objetivo fue estimar la efectividad de la vacuna (EV) trivalente inactivada para prevenir atenciones hospitalarias por gripe (AHG) en Guadalajara, Castilla-La Mancha (CLM), España, temporada 2018-2019. MATERIAL Y MÉTODOS: Estudio de cohortes retrospectivo; semanas 40/2018 a 13/2019. Fuentes: Programa Microbiología; historia clínica electrónica; censo poblacional (INE, 1/7/2018). Casos: AHG (urgencias y/u observación de urgencias o ingreso), confirmadas mediante prueba antigénica o PCR. Se calcularon: fracciones preventivas ([FPv(vacunados) y FPp(poblacional)]) y número necesario de pacientes a vacunar (NNV). RESULTADOS: Hubo 228 AHG (tasa incidencia [TI] acumulada=8,9/104; ≥ 65 años=65%; cobertura vacunal=13% [≥ 65 años=58%]; mortalidad=9%); con máxima incidencia en la semana 6.ª (TI=1,7/104) (en CLM, en la 4.ª). El mayor pico de VRS ocurrió en la 3.ª semana (en CLM, en la 52). La FPv entre 14-65 años fue del 96% (FPp=58%) y en ≥ 65, del 32% (FPp=21%). NNV=414. Como en España, predominó el virus A, siendo A(H3N2) un 13% más prevalente (cepa no concordante con la vacunal). CONCLUSIONES: La temporada se retrasó por una sostenida circulación del VRS. La EV resultó inferior a la nacional. Sería imprescindible impulsar próximas campañas para mejorar la cobertura

INTRODUCTION: The objective was to estimate the effectiveness of inactivated trivalent vaccine (VE) in preventing hospital flu care (HFC) in Guadalajara, Castile-La Mancha (CLM), Spain, 2018-19 season. MATERIAL AND METHODS: Retrospective cohort study (40/2018 to 13/2019 weeks). Sources: Microbiology programme; electronic medical history; population census (INE, 1/7/2018). Cases: Population requiring HFC (hospital emergencies and/or emergency observation unit and/or hospital admissions), confirmed by antigenic test and/or PCR. Preventive fractions [PFv(vaccinated) and PFp(population)] and Necessary number of patients to be vaccinated (NNV) were calculated. RESULTS: 228 HFT occurred [cumulative incidence rate (IR)=8.9/104; ≥65 years=65%; vaccination coverage=13% (≥65 years=58%); mortality=9%); maximum incidence in the 6th week (IR=1.7/104) (in CLM, in 4th)]. Highest peak of RSV occurred in the 3rd (in CLM, in the 52th). PFv (14-65 years) was 96% (PFp=58%) and in ≥65, 32% (PFp=21%). NNV=414. As in Spain, influenza virus A predominated, with A(H3N2) being 13% more prevalent (strain not included in the vaccine). CONCLUSIONS: The season was delayed by sustained VRS circulation. The VE was lower than the national one. It is be essential to promote future campaigns to improve vaccination coverage

Uso de sujeciones físicas en relación con el riesgo de caídas en una residencia de ancianos / Physical restraint use in relation to falls risk in a nursing home

ANTECEDENTES Y OBJETIVO: El uso de sujeciones físicas (SF) es común en el cuidado de los ancianos. Sin embargo, su eficacia y seguridad son cuestionadas por la evidencia científica. El objetivo de este estudio fue determinar el papel de las SF en la prevención de caídas. MATERIALES Y MÉTODOS: Se realizó un estudio de cohorte retrospectivo. Examinamos todas las caídas (n=575) que se produjeron en ancianos mayores de 65 años que residieron en una residencia entre febrero de 2009 y septiembre de 2013. Analizamos la asociación entre el uso de SF y riesgo de caídas mediante una regresión logística multivariable que ajusta las características de los residentes que se asociaron con el uso de SF según un análisis bivariado. RESULTADOS: Los factores de riesgo de caídas, teniendo en cuenta el uso de SF, fueron: riesgo de caída (Test de Tinetti) (OR 4,57; IC 95% 1,76-11,75); capacidad de caminar (OR 6,40; IC 95% 2,78-14,74); déficit auditivo (OR 2,12; IC 95% 1,05-4,29); y la historia de caídas (17,81; IC 95% 8,83-35,93). El riesgo de caídas fue mayor en los residentes sujetos ambulantes con deterioro cognitivo (OR 18,95; IC 95% 7,06-50,85). No encontramos diferencias en las lesiones entre las caídas que ocurrieron con y sin SF. CONCLUSIONES: El uso de SF no se asoció significativamente con menos caídas y lesiones. En los residentes ambulantes con deterioro cognitivo podrían aumentar el riesgo de caídas. Por tanto, habría que considerar si las SF proporcionan una protección adecuada contra el riesgo de caídas

BACKGROUNDS AND OBJECTIVES: The use of physical restraints (PR) is common in the care of the elderly. However, their efficacy and safety are not supported by scientific evidence. The aim of this study was to determine the role of PR in preventing falls. MATERIALS AND METHODS: A retrospective cohort study design was used, in which each fall incident (n=575) was examined in the residents over 65 years of age who resided at the one nursing homes from February 2009 to September 2013. An analysis was made of the association between the use of PR and risk of falls using a multivariate logistic regression, adjusting for the characteristics of residents that were associated with the use of PR according to a bivariate analysis. RESULTS: Risk factors for falls after accounting for PR use, include: risk of falling (Tinetti test) (OR 4.57; 95% CI 1.76-11.75); ability to walk (OR 6.40; 95% CI 2.78-14.74); hearing impairment (OR 2.12; 95% CI 1.05-4.29); and history of a previous fall (OR 17.81; 95% CI 8.83-35.93). The risk of falls was greater in restrained, ambulatory residents with cognitive impairment (OR 18.95; 95% CI 7.06-50.85). No differences were found in injuries between falls that occurred with and without PR. CONCLUSIONS: Restraint use was not significantly associated with fewer falls and injuries. The risk of falls could increase in ambulatory residents with cognitive impairment. The study results suggest the need to consider whether restraints provide adequate protection against the risk of falls

Vojta Therapy versus transcutaneous electrical nerve stimulation for lumbosciatica syndrome: A quasi-experimental pilot study.

BACKGROUND: Lumbosciatica is a common condition that affects patients' quality of life. OBJECTIVE: To determine the efficacy of Vojta Therapy and transcutaneous electrical nerve stimulation (TENS) in the treatment of lumbosciatica. METHODS: A "pre-post" quasi-experimental pilot study was carried out on 12 patients between 31 and 74 years of age who had been diagnosed with lumbosciatica and referred to the Physiotherapy Unit of the Quintanar de la Orden Health Center. Subjects were prescribed either TENS or Vojta, assigned alternately (6:6). All patients received one session of 30 min per day for 15 days. Tests to evaluate pain, disability, functionality, and radiculopathy were performed. RESULTS: The differences between pre-post measures and improvement after both treatments were analyzed with nonparametric tests. Significant improvements were noted after both treatments in indices for pain, disability, and flexibility, with the exception of disability after TENS, according to the Roland-Morris test (p = 0.066). Improvements in radiculopathy (Làsegue sign) were only observed with Vojta (p = 0.031). An overall decrease in scores obtained after Vojta was observed with respect to those obtained after TENS (difference V-T): pain according to the Visual Analog Scale (V-T = 2.84; p = 0.033) or Oswestry back pain (V-T = 2.67; p = 0.030) and leg pain tests (V-T = 3.25; p = 0.063); disability according to Oswestry (V-T = 28.33; p = 0.005) and Roland-Morris (V-T = 5.67; p = 0.044); flexibility according to Schöber (average gain V-T = 0.43; p = 0.292) and the fingertips to floor distance test (V-T = 7.5; p = 0.016). CONCLUSIONS: Vojta Therapy led to significantly greater improvements in pain, disability, flexibility, and radiculopathy than TENS. Future studies will require larger samples to confirm these findings.

Tendencia y estacionalidad de las resistencias de Escherichia coli comunitarios y su relación dinámica con el consumo de antimicrobianos mediante modelos ARIMA / Trend and seasonality of community-acquired Escherichia coli antimicrobial resistance and its dynamic relationship with antimicrobial use assessed by ARIMA models

INTRODUCCIÓN: Estudiamos la tendencia y estacionalidad de las resistencias en Escherichia coli comunitario y se cuantifica su asociación con el uso previo de determinados antibióticos. MÉTODOS: Estudio de series temporales de las resistencias de aislados comunitarios de E. coli y su relación con el consumo de antibióticos en un área de primaria durante 2008-2012. La tendencia y estacionalidad de las resistencias se estudiaron mediante regresión de Poisson. RESULTADOS: Se observó un aumento significativo de la resistencia promedio de E. coli a cefalosporinas, nitrofurantoína y aminoglucósidos. La estacionalidad de las resistencias fue significativa en otoño-invierno para amoxicilina-ácido clavulánico y ciprofloxacino. Observamos un retardo de 7, 10 y 12 meses entre el consumo de cotrimoxazol (p < 0,038), fosfomicina (p < 0,024) y amoxicilina-ácido clavulánico (p < 0,015), respectivamente, y la aparición de resistencias. CONCLUSIONES: Detectamos un retardo medio de 10 meses entre la utilización de amoxicilina-ácido clavulánico, cotrimoxazol y fosfomicina, y la aparición de cepas resistentes de E. coli comunitarios

INTRODUCTION: We studied the trend and seasonality of community-acquired Escherichia coli resistance and quantified its correlation with the previous use of certain antibiotics. METHODS: A time series study of resistant community-acquired E. coli isolates and their association with antibiotic use was conducted in a Primary Health Care Area from 2008 to 2012. A Poisson regression model was constructed to estimate the trend and seasonality of E. coli resistance. RESULTS: A significant increasing trend in mean E. coli resistance to cephalosporins, aminoglycosides and nitrofurantoin was observed. Seasonal resistance to ciprofloxacin and amoxicillin-clavulanic acid was significantly higher in autumn-winter. There was a delay of 7, 10 and 12 months between the use of cotrimoxazole (P < 0.038), fosfomycin (P < 0.024) and amoxicillin-clavulanic acid (P < 0.015), respectively, and the occurrence of E. coli resistance. CONCLUSIONS: An average delay of 10 months between the previous use of amoxicillin-clavulanic acid, cotrimoxazole and fosfomycin and the appearance of resistant community-acquired E. coli strains was detected

There was a delay of 7, 10 and 12 months between the use of cotrimoxazole (P<0.038), fosfomycin (P<0.024) and amoxicillin-clavulanic acid (P<0.015), respectively, and the occurrence of E. coli resistance. CONCLUSIONS: An average delay of 10 months between the previous use of amoxicillin-clavulanic acid, cotrimoxazole and fosfomycin and the appearance of resistant community-acquired E. coli strains was detected.

Validity and Reliability of Administrative Coded Data for the Identification of Hospital-Acquired Infections: An Updated Systematic Review with Meta-Analysis and Meta-Regression Analysis.

OBJECTIVE: To conduct an updated assessment of the validity and reliability of administrative coded data (ACD) in identifying hospital-acquired infections (HAIs). METHODS: We systematically searched three libraries for studies on ACD detecting HAIs compared to manual chart review. Meta-analyses were conducted for prosthetic and nonprosthetic surgical site infections (SSIs), Clostridium difficile infections (CDIs), ventilator-associated pneumonias/events (VAPs/VAEs) and non-VAPs/VAEs, catheter-associated urinary tract infections (CAUTIs), and central venous catheter-related bloodstream infections (CLABSIs). A random-effects meta-regression model was constructed. RESULTS: Of 1,906 references found, we retrieved 38 documents, of which 33 provided meta-analyzable data (N = 567,826 patients). ACD identified HAI incidence with high specificity (≥93 percent), prosthetic SSIs with high sensitivity (95 percent), and both CDIs and nonprosthetic SSIs with moderate sensitivity (65 percent). ACD exhibited substantial agreement with traditional surveillance methods for CDI (κ = 0.70) and provided strong diagnostic odds ratios (DORs) for the identification of CDIs (DOR = 772.07) and SSIs (DOR = 78.20). ACD performance in identifying nosocomial pneumonia depended on the ICD coding system (DORICD-10/ICD-9-CM  = 0.05; p = .036). Algorithmic coding improved ACD's sensitivity for SSIs up to 22 percent. Overall, high heterogeneity was observed, without significant publication bias. CONCLUSIONS: Administrative coded data may not be sufficiently accurate or reliable for the majority of HAIs. Still, subgrouping and algorithmic coding as tools for improving ACD validity deserve further investigation, specifically for prosthetic SSIs. Analyzing a potential lower discriminative ability of ICD-10 coding system is also a pending issue.

Association between atopic manifestations and eosinophilic esophagitis: A systematic review and meta-analysis.

BACKGROUND: Eosinophilic esophagitis (EoE) has repeatedly been associated with atopic manifestations, which are reported more frequently in these patients than in the general population. OBJECTIVE: To systematically assess the evidence and strength of the associations between EoE and atopy. METHODS: We performed a systematic search of the MEDLINE, EMBASE, and SCOPUS databases for case-control studies comparing the frequency of atopic diatheses among patients with EoE and control subjects representing the general population without EoE. Using random-effects meta-analyses, we calculated summary estimates, including 95% confidence intervals (CIs), for bronchial asthma, atopic rhinitis, and eczema. Publication bias risks were assessed by means of funnel plot analysis and specific statistical tests. RESULTS: Of the 2,954 references identified, data were collected from 21 studies, including a total of 53,542 patients with EoE and 54,759 controls. The criteria for defining a diagnosis of atopy in patients with EoE or controls was not structurally considered in most of the studies. Overall, allergic rhinitis was significantly more common among patients with EoE compared with control subjects (odds ratio [OR], 5.09; 95% CI, 2.91-8.90; I2 = 86.7%) as were bronchial asthma (OR, 3.01; 95% CI, 1.96-4.62; I2 = 84.5%) and eczema (OR, 2.85; 95% CI, 1.87-4.34; I2 = 57.1%). Food allergies and other atopic conditions were also assessed. No significant publication bias was found for studies dealing with allergic rhinitis and eczema in EoE. CONCLUSION: Despite pointing to a significant association between atopy and EoE, most of the studies provided no normalized diagnostic criteria for atopy. Further research should provide clear and standardized definitions of such conditions. TRIAL REGISTRATION: www.crd.york.ac.uk/PROSPERO Trial Identifier: CRD42016036161.

Quality assessment of clinical practice guidelines for eosinophilic esophagitis using the AGREE II instrument.

BACKGROUND: High-quality evidence-based clinical practice guidelines can guide diagnosis and treatment to optimize outcomes. We aimed to systematically review the quality of international guidelines on eosinophilic esophagitis (EoE). METHODS: MEDLINE and Scopus databases were searched for appropriate guidelines up to 2016. Two gastroenterologists and two methodologists independently evaluated the documents using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. RESULTS: Amongst the 25 records initially retrieved, four guidelines developed by recognized scientific organizations met inclusion criteria. AGREE II results varied widely across domains, but none achieved an overall assessment score of over 60%. Scope and purpose (61.82 ± 19.24%), clarity of presentation (57.13 ± 40.56%) and editorial independence (93.75 ± 1.69%) showed the highest mean rating, whereas stakeholder involvement (28.82 ± 11.19%), rigor of development (32.29 ± 12.02%) and applicability (21.62 ± 7.14%) did not reach quality thresholds. Intraclass correlation coefficients for agreement was excellent among appraisers (0.903), between gastroenterologists and methodologists (0.878) and for each individual guideline (0.838 to 0.955). CONCLUSION: Clinical practice guidelines for EoE vary significantly in quality, are invariably limited and currently, none can be 'strongly recommended'.

Sonographic assessment of the optic nerve sheath diameter in the diagnosis of idiopathic intracranial hypertension.

OBJECTIVE: Sonographic assessment of the optic nerve sheath diameter (ONSD) is a useful technique in detecting raised intracranial pressure (ICP) in neurocritical care patients. Its utility in idiopathic intracranial hypertension (IIH) is less known. The aim of this study was to evaluate the diagnostic accuracy of ONSD for detecting IIH. MATERIAL AND METHODS: Ultrasound measurement of ONSD was performed in 19 patients with IIH and in 11 patients with different neurological diseases without raised ICP that required undergoing a lumbar puncture. The validity of this technique for diagnosing IIH was established with cerebrospinal fluid manometry values. RESULTS: Patients with IIH showed significantly enlarged ONSD than those without IIH. The best cut-off point for detecting raised ICP was 6.3 mms, with a sensitivity, specificity and positive likelihood ratio of 94.7%, 90.9% and 10.4, respectively. After a therapeutic lumbar puncture an 87% of cases had a partial reduction of ONSD values. CONCLUSION: Sonographic assessment of ONSD seems to be a useful and reliable technique for detecting raised ICP. While the spinal manometry is not replaced in usual clinical settings, transorbital sonography alternatively allows a suitable and harmless screening of patients with suspected IIH. It would be desirable to perform an internal validation of the technique in each hospital in order to get the optimal cut-off point.

Validity and reliability of the minimum basic data set in estimating nosocomial acute gastroenteritis caused by rotavirus.

INTRODUCTION: Rotavirus is the principal cause of nosocomial acute gastroenteritis (NAGE) under 5 years of age. The objectiveis to evaluate the validity and reliability of the minimum basic dataset (MBDS) in estimating the NAGE caused by rotavirus (NAGER) and to analyze any changes during the three years that the Rotarix® and Rotateq® vaccines were used in Spain. MATERIAL AND METHODS: A descriptive, retrospectivestudy was carried out in the University Hospital of Guadalajara(UHG) (Spain) between 2003-2009 using the MBDS, positive microbiological results for rotavirus (PMRs), and medical histories.Three methods of estimation were used: 1) An ICD-9-CM code 008.61 in the secondary diagnosis fields (DIAG2) of MBDS; 2) method 1 and/or PMRs with a current or recent hospitalization; and 3) the reference method or method 2 contrasted with patient medical histories. The validity of methods 1 and 2 was determined -sensitivity, specificity, predictive values and likelihood ratios (LRs)-, along with their agreement with method 3 (Kappa coefficient). In addition, the incidence rate ratio between the NAGER rate in 2007-2009 (commercialization period of both vaccines) was calculated with respect to 2003-2005 (precommercialization period). RESULTS: Method 1 identified 65 records with a DIAG2 of 008.61. Method 2 found 62 probable cases, and the reference method, 49 true cases. The sensitivity of the MBDS was 67 %,the positive predictive value was 51 %, and both negative LR (LR-) and reliability were moderate (LR- 0.33, Kappa coefficient 0.58). During 2007-2009, the NARGE decreased by 5 cases per 103 hospitalizations and by 9 per 104 days of hospitalization. Method 2 overestimated both the decline in incidence by 2 per 103 hospitalizations and the decreased risk per day of stay by 10 %. The MBDS found no differences between the two three-year periods, but, like method 2, showed an excellent level of diagnostic evidence (LR+ 67). CONCLUSION: The MBDS taken together with microbiological results, is more exact, safer and more reliable than the MBDS alone in estimating NAGER; and more useful in ruling out it. Nevertheless, the MBDS alone may be used to estimate and compare such disease in contexts with different prevalences.
