Cross-cultural adaptation of the SCORE survey and evaluation of the impact of Real-Time Random Safety Audits in organizational culture: A multicenter study / Adaptación transcultural de la encuesta SCORE y evaluación del impacto de los análisis aleatorios de seguridad en tiempo real en la cultura organizacional: estudio multicéntrico

Objective To establish a cross-cultural adaptation of the Safety, Communication, Operational Reliability, and Engagement (SCORE) survey and to use this instrument to evaluate the impact of a safety intervention. Design Cross-cultural adaptation and before-and-after evaluation study. Setting 5 ICU. Participants Medical residents, attending physicians, and nurses at those ICU. Interventions Adaptation of the SCORE survey to Spanish culture. The adapted survey was used to assess all safety-culture-related domains before and one-year after implementing the use of a safety tool, Real-Time Random Safety Audits (in Spanish: Análisis Aleatorios de Seguridad en Tiempo Real, AASTRE). Main outcome measure Adaptabiliy of the Spanish version of SCORE survey in the ICU setting and evaluation of the effect of AASTRE on their domains. Results The cross-cultural adaptation was adequate. Post-AASTRE survey scores [mean (standard deviation, SD)] were significantly better in the domains learning environment [50.55 (SD 20.62) vs 60.76 (SD 23.66), p<.0001], perception of local leadership [47.98 (SD 23.57) vs 62.82 (SD 27.46), p<.0001], teamwork climate [51.19 (SD 18.55) vs 55.89 (SD 20.25), p=.031], safety climate [45.07 (SD 17.60) vs 50.36 (SD 19.65), p=.01], participation decision making [3 (SD 0.82) vs 3.65 (SD 0.87), p<.0001] and advancement in the organization [3.21 (SD 0.77) vs 4.04 (SD 0.77), p<.0001]. However, post-AASTRE scores were significantly worse in the domains workload and burnout climate. Conclusions The cross-cultural adaptation of the SCORE survey into Spanish is a useful tool for ICUs. The application of the AASTRE is associated with improvements in six SCORE domains, including the safety climate (AU)Objetivo

Long-term results of a prospective randomized trial of midline laparotomy closure with onlay mesh.

PURPOSE: Incisional hernia (IH) continues to be one of the most common complications of laparotomy. The short-term protective effect of the use of mesh has been demonstrated in several studies. At present, there is little evidence on the long-term results of the prophylactic use of mesh. The aim of the present study is to analyze the long-term prevention of IH 5 years after a midline laparotomy during elective surgery. METHODS: A prospective study was performed including all of the 160 patients that had been previously included in the prospective, randomized, controlled trial performed between May 2009 and November 2012. The protocol and results at 1 year have been previously published in 2014. The patients in group A (mesh) were fitted with a polypropylene mesh to reinforce the standard abdominal wall closure. The patients in group B (non-mesh) underwent a standard abdominal wall closure and were not fitted with the mesh. All patients were followed for 5 years or until the diagnosis of incisional hernia was made, further surgery was performed, or the patient died. Cases lost to follow-up were also registered. RESULTS: Five years after surgery, in group A (mesh) we have found 4/80 (5.1%) incisional hernias, while in group B (no mesh) 37/80 patients were diagnosed with an incisional hernia (46.8%). The Kaplan-Meier survival curves for these results show statistically significant differences (p > 0.001). CONCLUSION: The protective effect of the use of an onlay mesh in abdominal wall closure is significantly maintained in the long-term, up to 5 years after surgery.

Factores relacionados con el cumplimiento de la posición semiincorporada en el paciente con ventilación mecánica según los profesionales: cuestionario CAPCRI-Q / Factors associated with compliance to the semi-recumbent position in the patient on mechanical ventilation: CAPCRI-Q questionnaire

Objetivo: Elaborar un cuestionario (CAPCRI-Q) para determinar los factores relacionados con el cumplimiento de la posición semiincorporada en pacientes con ventilación mecánica. Metodología: Se creó un cuestionario cerrado a través de la revisión de la literatura y la práctica clínica. La versión inicial constó de 61 ítems englobados en 5 categorías: variables del paciente, factores de equipo y profesionales, de actividad, de formación y entrenamiento, y equipamiento y recursos. Para elaborar el cuestionario se usó el método Delphi. En cada ítem se evaluó la comprensión, la pertinencia y la importancia, así como las recomendaciones de los expertos. Se realizó una prueba piloto cualitativa con 9 profesionales y, posteriormente, una prueba piloto cuantitativa con 67 enfermeras de 6 unidades de cuidados intensivos para analizar la consistencia interna del instrumento. Resultados: Se requirieron 3 rondas con 15 expertos para llegar al consenso. La versión final del cuestionario constó de 36 ítems englobados dentro de las mismas categorías que la versión inicial. El análisis de consistencia interna mostró valores superiores a 0,800 para cada ítem, cada categoría y el cuestionario global (0,873; IC 95%: 0,825-0,913). El análisis de las respuestas destacó los factores individuales del paciente, así como los organizativos e infraestructurales, como factores relevantes en el cumplimiento de la recomendación. Conclusiones: El cuestionario creado es fiable y tiene validez aparente y de contenido. Los factores más influyentes en el cumplimiento son los relacionados con el paciente y organizativos. Los resultados pueden usarse para evaluar los factores influyentes en el cumplimiento y establecer estrategias de mejora

Aim: To create a questionnaire (CAPCRI-Q) to determine the factors associated with the compliance of the semi-recumbent position in patients under mechanical ventilation Methods: A closed questionnaire was created using a literature review and clinical practice. The initial version consisted of 61 items placed into 5 categories: patient factors, team and professionals factors, activity, educational and training factors, and equipment and resources. A Delphi method was used to prepare the questionnaire. Comprehension, relevance and importance of each item were evaluated, as well as the recommendations of experts. A qualitative pilot test with 9 healthcare professionals was performed, followed by a quantitative pilot test with 67 nurses from 6 intensive care units to test the internal consistency of the instrument. Results: Three rounds with 15 experts were required to reach a consensus. The final version of the questionnaire consisted of 36 items enclosed in the same categories as the initial version. The internal consistency analysis showed values greater than 0.800 for each independent item, each category, and for the global questionnaire (0.873; 95% CI: 0.825-0.913). The analysis of the nurses’ responses emphasised the importance of the patient factors, as well as organisational and infra-structural factors, for the compliance of the recommendation. Conclusions: The questionnaire created is reliable and appears to have content validity. The most influential factors for compliance are those related to the patient and the internal organisation. The results of the questionnaire can be used to evaluate the factors influencing the compliance and to establish improvement strategies

Grado de adherencia al tratamiento antivírico recomendado durante la pandemia y periodo pospandémico de gripe A (H1N1) pdm09 en 148 unidades de cuidados intensivos españolas / Degree of adherence to recommended antiviral treatment during the pandemic and post-pandemic periods of influenza A (H1N1) pdm09 in 148 intensive care units in Spain

OBJETIVO: Evaluar el grado de adherencia a las recomendaciones sobre el tratamiento antivírico y su impacto en la mortalidad de pacientes críticos afectados por gripe A (H1N1) pdm09. DISEÑO: Análisis secundario de estudio prospectivo. ÁMBITO: Medicina intensiva (UCI). PACIENTES: Pacientes con gripe A (H1N1) pdm09 en el periodo pandémico 2009 y pospandémico 2010-11. Variables La adherencia a las recomendaciones se clasificó en: total (AT), parcial dosis (PD), parcial tiempo (PT) y no adherencia (NA). La neumonía vírica, obesidad y ventilación mecánica fueron considerados criterios de gravedad para el uso de dosificaciones elevadas de antivírico (CG). Análisis mediante «chi» cuadrado y t-test. Supervivencia mediante regresión de Cox. RESULTADOS: Se incluyeron 1.058 pacientes, 661(62,5%) en pandemia y 397 (37,5%) en pospandemia. La AT global del estudio fue del 41,6% (el 43,9% y el 38%, respectivamente; p = 0,07). Los pacientes con criterios de gravedad no fueron diferentes en ambos periodos (un 68,5% y un 62,8%; p = 0,06). En estos pacientes la AT fue del 54,7% durante el 2009 y del 36,4% en pospandemia (p < 0,01). La NA (19,7% vs. 11,3%; p < 0,05) y la PT (20,8% vs. 9,9%; p < 0,01) fueron más frecuentes durante la pospandemia. La mortalidad fue mayor en la pospandemia (30% vs. 21,8%; p < 0,001). El APACHE II(HR = 1,09) y la enfermedad hematológica (HR = 2,2) se asociaron a mortalidad y la adherencia (HR = 0,47) fue un factor protector. CONCLUSIONES: Se evidencia un bajo grado de adherencia al tratamiento en ambos periodos. La adherencia al tratamiento antivírico se asocia con menor mortalidad y debería ser recomendada en pacientes críticos afectados por gripe A (H1N1) pdm09

OBJECTIVE: To determine the degree of antiviral treatment recommendations adherence and its impact to critical ill patients affected by influenza A (H1N1) pdm09 mortality. DESIGN: Secondary analysis of prospective study. SETTING: Intensive care (UCI). PATIENTS: Patients with influenza A(H1N1)pdm09 in the 2009 pandemic and 2010-11 post-Pandemic periods. Variables Adherence to recommendations was classified as: Total (AT); partial in doses (PD); partial in time (PT), and non-adherence (NA). Viral pneumonia, obesity and mechanical ventilation were considered severity criteria for the administration of high antiviral dose. The analysis was performed using t-test or «chi» square. Survival analysis was performed and adjusted by Cox regression analysis. RESULTS: A total of 1,058 patients, 661 (62.5%) included in the pandemic and 397 (37.5%) in post-pandemic period respectively. Global adherence was achieved in 41.6% (43.9% and 38.0%; P = .07 respectively). Severity criteria were similar in both periods (68.5% vs. 62.8%; P = .06). The AT was 54.7% in pandemic and 36.4% in post-pandemic period respectively (P <.01). The NA (19.7% vs. 11.3%; P <.05) and PT (20.8% vs. 9.9%, P < .01) was more frequent in the post-pandemic period. The mortality rate was higher in the post-pandemic period (30% vs. 21.8%, P <.001). APACHE II (HR=1.09) and hematologic disease (HR = 2.2) were associated with a higher mortality and adherence (HR=0.47) was a protective factor. CONCLUSIONS: A low degree of adherence to the antiviral treatment was observed in both periods. Adherence to antiviral treatment recommendations was associated with lower mortality rates and should be recommended in critically ill patients with suspected influenza A(H1N1)pdm09

Feasibility and utility of the use of real time random safety audits in adult ICU patients: a multicentre study.

PURPOSE: The two aims of this study were first to analyse the feasibility and utility (to improve the care process) of implementing a new real time random safety tool and second to explore the efficacy of this tool in core hospitals (those participating in tool design) versus non-core hospitals. METHODS: This was a prospective study conducted over a period of 4 months in six adult intensive care units (two of which were core hospitals). Safety audits were conducted 3 days per week during the entire study period to determine the efficacy of the 37 safety measures (grouped into ten blocks). In each audit, 50% of patients and 50% of measures were randomized. Feasibility was calculated as the proportion of audits completed over those scheduled and time spent, and utility was defined as the changes in the care process resulting from tool application. RESULTS: A total of 1323 patient-days were analysed. In terms of feasibility, 87.6% of the scheduled audits were completed. The average time spent per audit was 34.5 ± 29 min. Globally, changes in the care process occurred in 5.4% of the measures analysed. In core hospitals, utility was significantly higher in 16 of the 37 measures, all of which were included in good clinical practice guidelines. Most of the clinical changes brought about by the tool occurred in the mechanical ventilation and haemodynamics blocks. Multivariate analyses demonstrated that changes in the care process in each block were associated with the core hospital variable, staffing ratios and severity of patient disease. CONCLUSIONS: Real time safety audits improved the care process and adherence to the clinical practice guidelines and proved to be most useful in situations of high care load and in patients with more severe disease. The effect was greater in core hospitals.

The mortality rate was higher in the post-pandemic period (30% vs. 21.8%, P<.001). APACHE II (HR=1.09) and hematologic disease (HR=2.2) were associated with a higher mortality and adherence (HR=0.47) was a protective factor. CONCLUSIONS: A low degree of adherence to the antiviral treatment was observed in both periods. Adherence to antiviral treatment recommendations was associated with lower mortality rates and should be recommended in critically ill patients with suspected influenza A(H1N1)pdm09.

Quality of life in patients operated on for digestive neoplasia: a prospective study.

AIM: The aim of this study was to evaluate the quality of life in patients having surgery for a digestive neoplasm and to monitor how the patient's perception evolves during the first 6 months after surgery. METHOD: A prospective study was carried out on the pre and postoperative quality of life of patients undergoing surgery for a digestive system neoplasm between May 2009 and December 2010. Patients were asked to complete the Short Form (36) Health Survey questionnaire (SF-36; spanish version 1.4). RESULTS: The study included 80 patients. At 1 month after surgery there was a statistically significant improvement in some domains of the SF-36. At 6 months, a statistically significant improvement was seen in physical functioning, social functioning, mental health and in the two physical and mental domains. We also found statistically significant differences, with women having a worse quality of life. CONCLUSION: Comparison of quality of life before and 6 months after surgical intervention showed improvement in both the psychological and the physical elements. This can be attributed to the fact that the patients have had time to recover from the surgery.

Edema of the uvula: etiology, risk factors, diagnosis, and treatment.

Edema of the uvula (EU) is a rare occurrence sometimes associated with angioedema, urticaria, and anaphylaxis. We analyze the causes, predisposing factors, and characteristics of EU in a group of 58 patients with a mean (SD) age of 48.2 (15.2) years over the course of a year. Of the 58 patients studied, 49 (84.5%) were male and 44 (75.9%) presented isolated EU. Thirty-two patients (55.1%) with no clear etiology were classed as idiopathic. Snoring and a high body mass index were more prevalent in these patients. A variety of probable causes were identified in 26 patients (44.9%). In this group, EU was usually accompanied by urticaria, angioedema, and anaphylaxis and there was also a greater prevalence of atopy. We found that EU was idiopathic in just over half of the patients studied and that the predisposing factors were being overweight and having a tendency to snore. Patients with EU should be tested for allergies to drugs, airborne allergens, and food.

Caspase-3 and caspase-6 in ductal breast carcinoma: a descriptive study.

Caspases are the main point in the apoptotic process. We have collected some information from 210 cases of Ductal breast cancer (pT1 - pT2) such as tumour size, histological differentiation degree, lymph node status and tumor necrosis in the infiltrating component and we have evaluated the number of apoptotic cells or bodies by TUNEL technique as well as immunohistochemical studies to evaluate the expression of caspase 3 and caspase 6, and proliferation index. Our results show that lymph node status and cell atypism are independent prognostic factors for recurrence and mortality and only tumour size is an independent prognostic factor for recurrence. However, the apoptotic index and the immunohistochemical expression of caspases and cell proliferation index have not turned out to be independent prognostic factors neither for recurrence nor mortality. These results show that classic prognostic factors known until now are the most important factors to predict the evolution of the illness.

MR assessment of the repaired rotator cuff: prevalence, size, location, and clinical relevance of tendon rerupture.

The objectives of this study were to use magnetic resonance (MR) imaging to evaluate the prevalence, size, location, and clinical relevance of tendon rerupture following complete repair of full-thickness rotator cuff tear (RCT). A total of 78 surgically proven full-thickness rotator cuff tears in 74 patients were retrospectively included in the study. Clinical assessment was performed using the University of California at Los Angeles score. Postoperative MR imaging was evaluated to determine prevalence, size, and location of tendon rerupture. At a mean 48.4 months' follow-up, 62 shoulders (79.5%) had favorable outcomes and 45 shoulders (57.6%) showed rerupture on MR imaging studies. Reruptures were significantly more prevalent among patients with intermediate-to-bad outcomes (81.3%), with surgically demonstrated two-tendon tears (78.9%) or three-tendon tears (100%), and with preoperative fatty degeneration of the supraspinatus muscle greater than 1 (91.6%). Reruptures were also significantly larger in those subgroups. Complete repair of RCT of all sizes may have favorable outcomes in a significant proportion of patients in spite of a high prevalence of reruptures. Preoperative tear size and degree of muscle fatty degeneration influence the prevalence and rerupture size. After repair of supraspinatus tears, reruptures tend to invade the posterior aspect of the tendon.

Surgically repaired massive rotator cuff tears: MRI of tendon integrity, muscle fatty degeneration, and muscle atrophy correlated with intraoperative and clinical findings.

OBJECTIVE: Our goal in this study was to evaluate by means of MRI the clinical significance of tendon integrity, muscle fatty degeneration, and muscle atrophy in surgically repaired massive rotator cuff tears and to correlate these and other prognostic factors with intraoperative and clinical findings. MATERIALS AND METHODS: Twenty-eight surgically proven massive rotator cuff tears were retrospectively included in the study. Twenty-two patients underwent complete repair, and six patients underwent partial repair. Preoperative and postoperative clinical assessment was performed by using the University of California at Los Angeles score. Preoperative and postoperative MRI studies were evaluated for the presence and extent of rotator cuff tear and for the degree of fatty degeneration and atrophy of the rotator cuff muscles. RESULTS: At a mean 44.4 months' follow-up, 20 patients (71.4%) had a favorable result. A total of 25 patients (89.2%) showed postoperative full-thickness rotator cuff tear, 19 of which were reruptures. A sagittal preoperative rotator cuff tear of less than or equal to 34 mm showed a specificity of 100% for predicting a favorable outcome. A coronal postoperative rotator cuff tear of less than or equal to 34 mm showed a specificity of 85.7% and a positive predictive value of 92.9% for predicting a favorable outcome. A postoperative fatty degeneration of infraspinatus muscle less than or equal to 2 had a specificity of 87.5% and a positive predictive value of 90.9% for predicting a favorable outcome. CONCLUSION: Open repair of massive rotator cuff tears may reach a favorable outcome in a significant proportion of patients, despite a high rate of recurrent or residual tears. Oblique coronal sizes of the recurrent or residual tear of less than or equal to 34 mm and postoperative fatty degenerations of infraspinatus muscle of less than or equal to 2 may allow a favorable outcome.

Epidemiology of urticaria in Spain.

BACKGROUND: In spite of the frequency of chronic urticaria there are very few epidemiological studies of its prevalence and distribution. OBJECTIVE: We wanted to approach the real prevalence of chronic urticaria in a population-based study and to depict demographic distribution and personal perception of the disease. We also wanted to describe the frequency of acute urticaria episodes in the population studied. METHODS: We conducted a population-based study among adults in Spain. We questioned 5003 individuals after calculating a sample size for a maximum variability (conservative approach p=q=0.5). RESULTS: We found a 0.6% (95% CI: 0.4-0.8) prevalence of chronic urticaria. The prevalence is significantly higher in women than in men with a OR=3.82 (95%CI 1.56-9.37). Chronic urticaria is a self-limited disease, yet in 8.7% of cases chronic urticaria lasts from one to 5 years and in 11.3%, for more than 5 years. The average age of onset is 40 years. CONCLUSIONS: We offer large epidemiology study data on the prevalence of chronic urticaria. The prevalence of chronic urticaria has not yet been defined in an adult population-based study. With this work we offer such data to describe the prevalence and features of this disease.

Prognostic value of apoptosis in breast cancer (pT1-pT2). A TUNEL, p53, bcl-2, bag-1 and Bax immunohistochemical study.

Apoptosis or programmed cell death produces cells breaking into several fragments of nuclei, cytoplasm or both nuclei and cytoplasm, known as apoptotic bodies which can be visualized in haematoxylin-eosin staining. Some genes (promoters and suppressors) control this process and certain mutations may induce the expression of abnormal proteins, which can be detected by immunohistochemical staining. Apoptosis can be detected by the TUNEL method either identifying apoptotic bodies or cells at the initial stages of the fragmentation process. We have studied 186 cases of infiltrating ductal breast carcinoma, stages pT1-pT2, and analysed the prognostic significance of tumour recurrence and overall survival of apoptotic index (AI) through univariate and multivariate analysis. We have also studied the immunohistochemical protein expression of apoptosis promoter and suppressors gene (p53, nuclear expression; bcl-2 and Bax, cytoplasm expression; BAG-1, nuclear and cytoplasm expression). The results indicate prognostic significance of p53 and bcl-2 related to patient death and bcl-2 and tumour size to tumour recurrence, bcl-2 acting as a protector factor (apoptotic suppressor) in both situations. On the other hand, we have not found useful prognostic information of AI either to tumour recurrence or overall survival in univariate or multivariate studies. In this study, Bax expression does not provide a new prognostic role in breast carcinoma, although it contrasts to the bcl-2 action and accelerates death.

Low risk of contrast nephropathy in high-risk patients undergoing spiral computed tomography angiography with the contrast medium iopromide and prophylactic oral hydratation.

BACKGROUND: Spiral computed tomography angiography (CTA) is a sensitive and specific technique for visualizing renal arteries and diagnosing renal artery stenosis (RAS). Whether spiral CTA is associated with increased risk of contrast nephropathy (CN) in patients with impaired renal function is unknown. METHODS: We prospectively studied 50 patients with chronic renal insufficiency (serum creatinine concentration greater than 1.58 mg/dl) who underwent spiral CTA with iopromide, a nonionic, low-osmolar contrast agent. Fourteen patients had diabetes mellitus. Patients were encouraged to drink 1 l of water 12 hours before and 2 l over 24 hours after the procedure. The presence of CN was defined by an increase of 20% or more in the baseline serum creatinine level within or 72 hours after administration of the radio-contrast agent. RESULTS: In the entire group, mean serum creatinine levels increased significantly from 2.92 +/- 1.39 to 3.06 +/- 1.55 mg/dl (p = 0.02) and mean creatinine clearance decreased from 29.8 +/- 12.9 to 28.9 +/- 12.8 ml/min (p = 0.009) 72 h after administration of the contrast medium. Two patients experienced an increase in serum creatinine level of 20%. Renal function returned to baseline within seven days in the 2 patients. Absolute changes in creatinine clearance after the administration of radiocontrast medium were similar in nondiabetic and diabetic patients and in the subgroup of patients, with a baseline serum creatinine of < 3 mg/dl and > or = 3 mg/dl. CONCLUSIONS: In patients with chronic renal insufficiency, spiral CTA performed with iopromide, a nonionic, low-osmolar contrast medium and a prophylactic oral hydratation, is a minimally invasive technique with low risk of contrast nephropathy.

Prevalencia de alergia en la población adulta española / Allergy prevalence in adult spanish population

Introduccián: En lo últimos decenios se está registrando un aumento de las enfermedades alérgicas en todo el mundo. Sin embargo hay pocos estudios de prevalencia de alergia en la población general española. Objetivos: Establecer la prevalencia de enfermedades alérgicas en una muestra de población general adulta del estado español. Así como establecer las causas y las manifestaciones de esta alergia. Material y métodos: Se realizó un estudio observacional de tipo tranversal. El tamaño de la muestra. suponiendo un nivel máximo de indeterminación prevalencia = 50%) y aceptando un error del 1.4% y un nivel de confianza del 95%. Fue de 5.003 sujeto . La muestra e seleccionó de forma aleatoria y automática del listín de teléfono, aplicando el control de cuotas de zona. el número de habitantes, el sexo y la edad. La recogida 1:1e datos se efectuó mediante encuesta telefónica siguiendo la técnica CATI (Computer-assisted Telephone Interview technique) con oporte Omnibus Phonebus de Taylor Ne/son Sofres Market Research. Resultados: De los 4.949 sujetos incluidos en el análisis. un 21,6% (IC 95% 20,4- 22,7%) refirieron ser alérgicos. La prevalencia fue mayor en mujeres (24,6%), en el grupo de 18 a 24 años de edad (26.9%) y en poblaciones de más de 500.000 habitantes (24,3%). mientras que fue menor en los varones (18,3%), en la región norte-centro ( 17 ,8%) y en poblaciones con menos de 10.000 habitantes ( 18.7% ). o hubo diferencia significativa en relación al nivel socioeconómico. La rinoconjuntivitis fue la manifestación alérgica más frecuente (45,4%) seguida del asma bronquial (24.9% ), la urticaria (24.6% ), la dermatitis (21,5%) y el angioederna (6% ). Las tres causas más frecuente de alergia fueron con diferencia los pólenes (31,5%). los medicamento (29,4%) y los ácaros del polvo domé tico (25.3%). Mucho menos frecuentes fueron los animales (6,8%). los metales (4.9%). los alimentos (4.8%), los hongos (3%), las picadura de insecto (2.5%), la exposición al sol (1,9%) y el látex (0,8%). Conclusiones: La prevalencia de alergia en la población adulta española es del 21,6%, y es más frecuente en las mujeres y en los núcleos urbanos de más de 500.000 habitantes. La manifestación más frecuente es la rinoconjuntivitis. Las manifestaciones cutáneas de la alergia no son despreciables. Las causas más frecuentes de alergia con los aeroalérgeno (pólenes y ácaros) y lo medicamentos (AU)

Background: In spite of the worldwide increase in allergic diseases over the recent years, few epidemiological studies have been conducted in Spain. Objective: We wanted to establish the real prevalence of allergy in a sample of adult general population. We then wanted to describe the profile. the causes and the type of caused disease. Methods: We conducted a population-based study among adults in Spain. We questioned 5003 individuals after calculating a simple size for a máximum undetermination level of (p = 50%). assuming a 1.4 error for global results and a 95% confidence interval (95% CI) l. Five thousands and three individual: were randomly selected from the telephone directory and matched according to sex, age and area. The phone survey was performed with each individual employing the Computer-assisted Telephone lnterview technique supported by Taylor elson Phonebus Company (Barcelona, Spain). Results: We found a 21.6% (95% CI: 20.4-22, 7%) prevalence of allergy. The prevalence was higher in wornen (24.6%) than in men (18.3%). Allergy condition was higher from 18 to 24 years old (26.9%). As it was expected. the prevalence was also higher in urban cities > 500.000 habitants (24.3%) than in rural cities with less than 10.000 habitants ( 18. 7% ). We did not find differences among economical status. The most cornrnon manifestation of allergic disease was rhinoconjunctivitis (45..+%) followed by bronchial asthrna (24.99'c), urticaria (24.6%). Dermatitis (21.5% ), and angioedema (6

Magnetic resonance imaging of anterior cruciate ligament tears: reevaluation of quantitative parameters and imaging findings including a simplified method for measuring the anterior cruciate ligament angle.

We evaluated the diagnostic utility of magnetic resonance imaging (MRI) for predicting anterior cruciate ligament (ACL) tears using both quantitative parameters and nonquantitative imaging findings. MRI examinations were retrospectively evaluated in a group of patients with arthroscopically confirmed complete ACL tear and in a control group with arthroscopically confirmed intact ACL. We evaluated multiple MRI features to compare their sensitivity and specificity for detecting ACL tears. Particular emphasis is put on the evaluation of three different quantitative parameters, including a simplified method for measuring the ACL angle. With a threshold value of 45 degrees the ACL angle reached a sensitivity and specificity of 100% for detecting ACL tears. With a threshold value of 0 degrees the Blumensaat angle had a sensitivity of 90% and a specificity of 98%. Finally, a threshold value of 115 degrees gave the posterior cruciate ligament angle a sensitivity of 70% and a specificity of 82%. Discontinuity was found to be the most useful of the ACL abnormalities. Of the secondary findings anterior tibial displacement was the best predictor of ligamentous injury. However, ACL abnormalities and secondary findings, alone or combined, failed to surpass the diagnostic value of the ACL angle for predicting ACL tears. Quantitative parameters are thus good predictors of ACL tears and may increase the overall sensitivity and specificity of MRI. The ACL angle may be confidently measured in a single MRI section and can be considered to be the most reliable quantitative parameter for detecting ACL tears.

[National survey of preoperative management and patient selection in ambulatory surgery centers]. / Encuesta nacional sobre manejo preoperatorio y criterios de selección de pacientes en las unidades de cirugía mayor ambulatoria españolas.

BACKGROUND: The objective of this study was to determine both the selection and preparation criteria in patients in various Spanish ambulatory surgery centers, as well as the impact of these criteria on their results. The results were compared according to the type of functional structure of the units (autonomous or integrated). MATERIAL AND METHODS: We performed a cross sectional, descriptive study through postal survey. The survey contained the following items: type of unit, surgical procedures, selection criteria, preoperative assessment and management, and qualitative and quantitative indexes of the activity performed in 2000. A total of 123 units were included with a response rate of 39%. RESULTS: The selection criteria showed a high degree of consensus. The outpatient anesthesia clinic was used for preoperative assessment by 97.9% of the units. Most units routinely requested preoperative tests (hemostasis and hemogram by 89%; biochemical parameters by 72.9%) and to a lesser extent chest X-ray (33.3%) and electrocardiogram (35.4%). The introduction of procedures for the management of coexisting diseases was scarce (25-64.6%). Units using the outpatient anesthesia clinic in all patients had a lower cancellation rate (1.5% vs 4.4%). Autonomous units were significantly more likely to accept patients with high surgical-anesthetic risk than integrated units. Autonomous units also showed a significantly lower number of admissions (1.2% vs 1.9%, p = 0.003), mean stay (240 min vs 367 min, p = 0.002), and recovery time (150 min vs 212 min, p = 0.001) than integrated units. No statistically significant differences were found in the remaining parameters. CONCLUSIONS: Scientifically based protocols for patient selection, preoperative assessment and perioperative management of distinct processes and for the rational use of laboratory tests should be more widely used. The need for an outpatient anesthesia clinic for preoperative assessment was notable. The results of our survey indicate that better results in performance indexes are achieved in autonomous ambulatory surgery units than in integrated units. Given the possibility of defining and validating quality standards, further multicenter studies should be performed.
