A Prospective Study of Costs Associated With the Evaluation of Allergic Reactions to Radiological Contrast Media.

BACKGROUND AND OBJECTIVE: The prevalence of hypersensitivity reactions to radiological contrast media (RCM) is increasing owing to the improved performance of diagnostic and therapeutic tests that require RCMs. Objective: We carried out a year-long real-life observational study to prospectively evaluate patients referred to the allergy department from primary care, the emergency department, and other specialties with suspected moderate-to-severe RCM hypersensitivity reactions. METHODS: To study the costs of evaluating RCM hypersensitivity reactions, we systematically recorded direct and indirect costs. RESULTS: Sixty-nine patients with previous reactions to RCM were evaluated in the allergy department from June 1, 2017, to May 31, 2018.Total direct health care costs were €10 715.84, with a mean (SD) cost per patient of €155.30 (77.08). Specifically, direct non-health care costs reached €1605.42 (mean, €23.27 [41.14]), and indirect costs were €6490.85 (mean, €94.07 [110.61]). In summary, the total cost was €18 812.11, that is, a mean cost of €272.64 (164.77). CONCLUSION: Our study shows that the costs of an elective evaluation of hypersensitivity reactions to RCM are low, thus confirming that correct and safe management of affected patients are cost-effective. Therefore, our efforts should be directed toward ensuring the necessary logistics.

Antecedentes: La prevalencia de reacciones de hipersensibilidad a los medios de contraste radiológico (MCR) está aumentando debido al incremento en la realización de pruebas diagnósticas y terapéuticas que requieren MCR. Objetivo: Hemos realizado un estudio observacional de un año de duración para evaluar prospectivamente a los pacientes remitidos al Servicio de Alergología con sospecha de reacciones moderadas a graves por hipersensibilidad a MCR.Métodos: Para estudiar los costes de la evaluación de la hipersensibilidad a MCR, se registraron sistemáticamente los costes directos e indirectos. Resultados: Se evaluaron 69 pacientes con reacciones previas a MCR remitidos al Servicio de Alergología desde el 1 de junio de 2017 hasta el 31 de mayo de 2018. Los costes sanitarios directos totales fueron de 10.715,84 €, con un coste medio por paciente de 155,30 € ± 77,08. En concreto, los costes directos no sanitarios alcanzaron los 1.605,42 € (media 23,27 € ± 41,14 €) y los costes indirectos fueron de6.490,85 € (media 94,07 € ± 110,61 €). En resumen, el coste total fue de 18.812,11 €, lo que supone un coste medio de 272,64 ± 164,77 €. Conclusiones: Nuestro estudio refleja que los costes de una evaluación electiva de hipersensibilidad a MCR son bajos. Este hecho reafirma que el manejo correcto y seguro de estos pacientes podría ser rentable, por lo que nuestros esfuerzos deben estar dirigidos a implementar la logística necesaria (AU)

A Comprehensive Prospective Study of the Costs Associated With Evaluation of ß-Lactam Allergy.

BACKGROUND AND OBJECTIVE: Being labeled as allergic to penicillin (unverified ß-lactam allergy) can result in patients receiving broader-spectrum antibiotics than necessary that may be more toxic, less effective, and/or more expensive than alternative options. Objective: We aimed to evaluate the real costs of evaluating ß-lactam allergy. METHODS: We performed a prospective real-life observational study designed to evaluate all adult patients who consulted for suspected ß-lactam allergy over a 1-year period. Direct and indirect costs were systematically recorded. Direct health costs were calculated based on the number of visits and all additional and diagnostic tests performed, direct nonhealth costs based on the number of visits and the distance from their homes to the Allergy Department, and indirect costs based on absenteeism. RESULTS: A total of 296 patients with suspected allergy to ß-lactams were evaluated in our outpatient clinic from June 1, 2017 to May 31, 2018. Total direct health care costs were €28 176.70, with a mean (SD) cost of €95.19 (37.20). Direct nonhealth costs reached €6551.73, that is, €22.13 (40.44) per patient. Indirect health costs reached €20 769.20, with a mean of €70.17 (127.40). In summary, the total cost was €55 497.63, that is, a cost per patient of €187.49 (148.14). CONCLUSIONS: When all possible costs are taken into account, the evaluation of ß-lactam allergy is not expensive and can reduce future expense arising from unnecessary use of more expensive and less effective antibiotics.

A Comprehensive Prospective Study of the Costs Associated With Evaluation of beta-Lactam Allergy

BACKGROUND: Being labeled as allergic to penicillin (unverified beta-lactam allergy) can result in patients receiving broader-spectrum antibiotics than necessary that may be more toxic, less effective, and/or more expensive than alternative options. OBJECTIVE: We aimed to evaluate the real costs of evaluating beta-lactam allergy. METHODS: We performed a prospective real-life observational study designed to evaluate all adult patients who consulted for suspected beta-lactam allergy over a 1-year period. Direct and indirect costs were systematically recorded. Direct health costs were calculated based on the number of visits and all additional and diagnostic tests performed, direct nonhealth costs based on the number of visits and the distance from their homes to the Allergy Department, and indirect costs based on absenteeism. RESULTS: A total of 296 patients with suspected allergy to beta-lactams were evaluated in our outpatient clinic from June 1, 2017 to May 31, 2018. Total direct health care costs were (Euro)28 176.70, with a mean (SD) cost of (Euro)95.19 (37.20). Direct nonhealth costs reached (Euro)6551.73, that is, (Euro)22.13 (40.44) per patient. Indirect health costs reached (Euro)20 769.20, with a mean of (Euro)70.17 (127.40). In summary, the total cost was (Euro)55 497.63, that is, a cost per patient of (Euro)187.49 (148.14). CONCLUSIONS: When all possible costs are taken into account, the evaluation of beta-lactam allergy is not expensive and can reduce future expense arising from unnecessary use of more expensive and less effective antibiotics

INTRODUCCIÓN: Un diagnóstico no verificado de alergia a la penicilina o a los betalactámicos (BL) conlleva que los pacientes reciban antibióticos de amplio espectro, que pueden ser más tóxicos, menos efectivos, y/o de mayor coste. OBJETIVO: Evaluar los costes reales de un estudio de alergia a los betalactámicos. MÉTODOS: Se diseñó un estudio observacional prospectivo en condiciones de práctica clínica habitual en el que se evaluaron todos los pacientes adultos que consultaron por sospecha de alergia a BL durante un año. Los costes directos e indirectos se recogieron sistemáticamente. Los costes directos sanitarios se calcularon teniendo en cuenta el número de visitas y todas las pruebas diagnósticas realizadas; en los costes directos no sanitarios se consideraron el número de visitas y los kilómetros desde el domicilio hasta el Servicio de Alergología; en los costes indirectos se evaluó el absentismo. RESULTADOS: Se evaluaron 296 pacientes remitidos desde el 1 de junio de 2017 hasta el 31 de mayo de 2018. Los costes directos totales sanitarios fueron 28.176,70 (Euro): coste medio (desviación estándar, DS) de 95,19 (Euro) (37,20). Los costes directos no sanitarios alcanzaron, 6.551,73: coste medio 22,13 (40,44). Los costes indirectos fueron 20.769,20 (Euro): coste medio (DS) 70,17 (127,40). En resumen, la cantidad total fue de 55.497,63 (Euro), lo que supone un coste medio de 187,49 (Euro) (148,14). CONCLUSIONES: Considerando todos los costes posibles, la evaluación de la alergia a betalactámicos no es cara y puede ahorrar gastos futuros debido a una utilización innecesaria de antibióticos más caros y menos efectivos

Consensus document on dog and cat allergy.

The prevalence of sensitization to dogs and cats varies by country, exposure time and predisposition to atopy. It is estimated that 26% of European adults coming to the clinic for suspected allergy to inhalant allergens are sensitized to cats and 27% to dogs. This document is intended to be a useful tool for clinicians involved in the management of people with dog or cat allergy. It was prepared from a consensus process based on the RAND/UCLA method. Following a literature review, it proposes various recommendations concerning the diagnosis and treatment of these patients, grounded in evidence and clinical experience. The diagnosis of dog and cat allergy is based on a medical history and physical examination that are consistent with each other and is confirmed with positive results on specific IgE skin tests. Sometimes, especially in polysensitized patients, molecular diagnosis is strongly recommended. Although the most advisable measure would be to avoid the animal, this is often impossible and associated with a major emotional impact. Furthermore, indirect exposure to allergens occurs in environments in which animals are not present. Immunotherapy is emerging as a potential solution to this problem, although further supporting studies are needed.

[TVT and TOT for surgical correction of female stress urinary incontinence. Comparison between techniques]. / TVT y TOT para la corrección quirúrgica de la incontinencia femenina de stress. Comparacion de ambas técnicas.

OBJECTIVES: Retrospective analysis of a series of patients with stress urinary incontinence that underwent surgery in our department, by means of the TVT and TOT techniques. We evaluate post operative continence, considering "cured" the patient with complete continence and "failure" any type of involuntary stress urine leak, independently of its severity registering the time of its appearance. For this purpose we used the Kaplan-Meier analysis comparing both techniques with the Breslow test. Additionally, postoperative complications were evaluated. RESULTS: 128 patients who underwent surgery by TVT (69 patients, 53.9%) and TOT (59 patients, 46.1%). Mean age was 54.4 years for TVT (95% CI 52.0-56.8) and 59 years for TOT (95% CI 55.9-62.1). Mean follow-up time was 18.7 months for TVT (95% CI 15.6-21.9) and 7.4 months for TOT (95% CI 5.8-8.9). Overall continence rate was 86.7%, 88.4% for TVT and 84.7% for TOT The probability of being continent six months after surgery was 89.1% for TVT and 78.2% for TOT (no significant differences, p = 0.31), with almost all failures within the first six months after surgery. TVT was more frecuently associated with urgency symptoms (33.3%, p = 0.001) and urge incontinence (18.8%,p = 0.16), urinary retention (11.6%, p = 0.38), and prevesical hematoma requiring mesh retrieval. Greater post operative pain was observed with TOT (20.3%, p = 0.005). CONCLUSIONS: Our results evidence a similar efficacy with both techniques, with the failures appearing over the first months after surgery. Complications of the voiding urgency type are significantly more frequent with TVT.

TVT y TOT para la corrección quirúrgica de la incontinencia femenina de stress. Comparación de ambas técnicas / TVT and TOT for surgical correction of female stress urinary incontinence. Comparison between technique

Objetivo: Evaluar los resultados en nuestras manos con las técnicas TVT y TOT. Métodos: Análisis retrospectivo de pacientes con incontinencia urinaria de esfuerzo operadas en nuestro servicio, mediante las técnicas de TVT y TOT. Evaluamos la continencia postoperatoria, considerando a las pacientes curadas si presentaban continencia total y como fracaso a cualquier tipo de pérdida involuntaria con el esfuerzo, independientemente de su severidad, registrándose el momento de su aparición. Para ello se empleó un análisis Kaplan-Meier comparando ambas técnicas mediante test de Breslow. Además se evaluaron las complicaciones postoperatorias. Resultados: El análisis se realizó con 128 pacientes intervenidas mediante TVT (69 pacientes, 53,9%) y TOT (59 pacientes, 46,1%). La media de edad para el TVT fue de 54,4 años (IC 95% 52,0-56,8), y de 59 años para el TOT (IC 95% 55,9-62,1). El tiempo medio de seguimiento fue 18,7 meses (IC 95% 15,6-21,9) para el TVT y 7,4 meses (IC 95% 5,8-8,9) para TOT. La tasa global de continencia fue de 86,7%, siendo de 88,4% para TVT y 84,7% para TOT. La probabilidad de permanecer continente a partir de los 6 meses de la cirugía fue de 89,1% para el TVT y de 78,2% para el TOT (diferencia no significativa, p=0,31), con la práctica totalidad de los fracasos antes de los 6 meses postcirugía. Con el TVT se produjo mayor sintomatología de urgencia (33,3%, p= 0,001) e incontinencia de urgencia (18,8%, p= 0,16), retención de orina (11,6%, p=0,38), y dos pacientes con hematoma prevesical que requirieron la retirada de la malla. Se observó mayor dolor postoperatorio con el TOT (20,3%, p=0,005). Conclusiones: Nuestros resultados evidencian una eficacia similar con ambas técnicas, presentándose los fracasos durante los primeros meses tras el procedimiento. Las complicaciones tipo urgencia miccional son significativamente mayores con el TVT (AU)

[Urinary stress incontinence: surgical experience in our center]. / Incontinencia de esfuerzo: experiencia quirúrgica en nuestro centro.

INTRODUCTION: For the treatment of the urinary stress incontinence, there are many techniques, and today the gold standard is that described by Burch. We compared the global and each technique results about rates of postoperative continence and complications seen in our experience. MATERIALS AND METHODS: We made a retrospective analysis of 292 women that have the first surgery for urinary stress incontinence in our centre, between 1991 and 2006. We considered cure the patient who did not have any level of incontinence postoperative, we made a Kaplan-Meier analysis for the postoperative continence evaluation. Besides we studied the behaviour of the postoperative complications found. RESULTS: Mean age was 53.6 years old, and mean time of follow up was 15.6 months. The vaginal techniques were the most practised (138), followed by the TVT (57), abdominal Burch (38), vaginal wall Sling (33), and the less was the laparoscopic Burch (26). The best rates of postoperative continence after 2 years were observed in the patients treated by TVT (87.6%), then with vaginal wall Sling (84.9%), laparoscopic Burch (59.3%), abdominal Burch (59.1%), and the worst with vaginal techniques (48.2%) (p = 0.007). We found more urgency and urge incontinence in the patients treated by TVT (36.8% y 21.1% respectively), and postoperative pain with vaginal techniques (36.2%). Postoperative urine retention and postoperative high residual urine more with the vaginal wall sling (54.5%) and vaginal techniques (26.1%) respectively. CONCLUSIONS: We have the best results for the incontinence treatment in our population with the TVT technique.

Introducción: Para el tratamiento quirúrgico de la incontinencia urinaria de esfuerzo existen múltiples técnicas, en la actualidad la de referencia es la descrita por Burch. Comparamos los resultados globales y de cada técnica en cuanto a las tasas de continencia postoperatoria y de complicaciones observadas en nuestra experiencia. Materiales y métodos: Hicimos un análisis retrospectivo de 292 mujeres operadas por primera vez por presentar incontinencia urinaria de stress en nuestro Centro, entre 1991 y 2006. Consideramos a las pacientes curadas si no presentaban ningún grado de incontinencia postoperatoria, se realizó un análisis de Kaplan – Meier para la evaluación de la continencia postoperatoria. Además estudiamos el comportamiento de las complicaciones postoperatorias presentadas. Resultados: La media de edad de las pacientes fue de 53,6 años, con un tiempo de seguimiento medio de 15,6 meses. La mayoría de las intervenciones fueron técnicas vaginales (138), seguida por los TVT (57), Burch abdominal (38), Sling con parche de vagina (33), y la menos utilizada fue el Burch laparoscópico (26). Las mejores tasas de continencia postoperatoria a los dos años se consiguieron con el TVT (87,6%), luego con el Sling con parche de vagina (84,9%), las siguientes con Burch laparoscópico (59,3%), Burch abdominal (59,1%), y las peores con técnicas vaginales (48,2 %), (p=0,007). Se observó mayor urgencia y urgencia-incontinencia postoperatorias en las pacientes operadas mediante TVT (36,8% y 21,1% respectivamente), y mayor dolor postoperatorio tras las técnicas vaginales (36,2%). La retención urinaria postoperatoria y residuo postmiccional elevado más comunes entre el Sling con parche de vagina (54,5%) y las técnicas vaginales (26,1%) respectivamente. Conclusiones: La técnica con mejores resultados para manejo de incontinencia en nuestra población es el TVT

Selective hypersensitivity to boiled razor shell.

Many types of seafood require cooking before ingestion and it has been demonstrated that this cooking process may affect the antigenicity and allergenicity of the food. We describe a case of anaphylaxis caused by selective sensitization to razor shell, a mollusc. In vivo and in vitro studies confirmed sensitization to boiled razor shell. Analysis of the nature of the allergen yielded results that were consistent with the findings of other authors and suggested that allergens involved in seafood allergy are commonly high molecular weight proteins that, in most cases, are heat stable.

Rhinitis and asthma due to ranitidine.

Few reports exist on allergic reactions to ranitidine. We present a case of bronchospastic reaction to ranitidine occurred during a drug challenge test. After administration of a therapeutic dose of ranitidine, the patient showed dyspnea, cough and bronchospasm in all the lung fields. Personal respiratory background was negative for respiratory disease and asthma. On reviewing the literature we found no reports of bronchospastic reaction to ranitidine. Quickness and the clinical characteristics of the adverse reaction suggest a pathogenic mechanism of immediate-type hypersensitivity.

Traqueostomía percutánea de emergencia en un paciente politraumatizado / Emergency percutaneous tracheostomy in a polytraumatised patient

El abordaje de la vía aérea difícil en situación de urgencia supone un reto continuo para los médicos que trabajan con pacientes críticos. La técnica de la traqueostomía percutánea mediante múltiples dilatadores de calibre progresivo fue descrita por Ciaglia en1985. Desde entonces se han desarrollado nuevas variantes de las técnicas percutáneas por dilatación. Actualmente disponemos de procedimientos más sencillos, rápidos y con baja tasa de complicaciones, cuando son realizados por personal experimentado. Este hecho hace que las técnicas percutáneas actuales puedan plantearse, en determinadas situaciones, como alternativa a la cricotiroidotomía en el manejo de la vía aérea difícil en situación de urgencia, ofreciendo algunas ventajas sobre ésta. Presentamos un caso clínico que ilustra el abordaje de la vía aérea difícil en un paciente politraumatizado mediante la técnica de traqueostomía percutánea por dilatación en un solo paso con dilatador de calibre progresivo con cubierta hidrofílica (Ciaglia BlueRhino. Cook Critical Care®, Bloomington, EEUU) (AU)

Approaching the difficult airway in an emergency situation represents a continuing challenge for physicians working with critical patients. The technique of percutaneous tracheostomy by means of multiple progressive-size dilators was described by Ciaglia in 1985. since then, new variations have been developed in the percutaneous dilation techniques. At present we have available simpler and quicker procedures with a lower complication rate when they are carried out by experienced personnel. Because of this the current percutaneous techniques may be put forward, undercertain circumstances, as an alternative to cricothyroidotomy in the emergency management of the difficult airway, providing some advantages over the latter. We present one case illustrating the approach to the difficult air way in a polytraumatised patient using the single-step dilation percutaneous tracheostomy technique with a progressive-size dilator with hydrophylliccoating (Ciaglia Blue Rhino. Cook Critical Care®, Bloomington, USA) (AU)

Sensibilización al polen de Olea europaea en las diferentes comarcas de la provincia de Zamora / Pollen sensitization to Olea europaea in the different regions of Zamora province

La sensibilización al polen de olivo en la provincia de Zamora debería ser mínima debido a que el olivo, por sus características, no se adapta bien a las condiciones climáticas y a que se ha introducido recientemente en la mayoría de las zonas de la provincia como árbol ornamental. Hemos realizado un estudio retrospectivo descriptivo que ha observado una sensibilización llamativa al polen del olivo, que aumenta en las zonas urbanas

Sensitization to olive pollen should not be important in Zamora city and province because, due to its characteristics, this tree doesn´t adapt to weather conditions in the city and because it has been recently introduced in most of the province’s areas as an ornamental tree. We have performed a retrospective descriptive study observing a significant level of sensitization to olive pollen, which is growing in urban zones

Angioedema induced by inhalation of vapours from cooked white bean in a child.

BACKGROUND: There are few references of allergic reaction to beans in childhood. We report the case of a seven years old boy who suffered from angioedema associated to inhalation of vapours from cooked white bean. METHODS: skin prick tests (SPT) were performed by prick-by-prick with cooked white bean and legumes. It was also determined total IgE and specific IgE antibodies to bean and legumes with the use of the CAP enzymo-immunoassay. Subsequently, a oral challenge test was carried out with white bean. RESULTS: The prick-by-prick with white bean was positive in our case, and negative in ten controls patients. Specific IgE in patient serum, assayed by CAP was positive for white bean and green bean. The patient developed angioedema after ingestion cooked white bean. CONCLUSION: we demonstrated a type I hypersensitivity to white bean in a seven years old child by SPT, specific IgE antibodies and challenge test.

Antecedentes: Hay pocas referencias de reacciones alérgicas a alubias en la infancia. Presentamos el caso de un niño de siete años que refiere angioedema asociado a la inhalación de vapores de alubias blancas cocidas. Métodos: Se realizaron pruebas cutáneas por prick-by-prick con alubia blanca y legumbres. También se determinó IgE total e IgE específica a legumbres. Posteriormente, se realizó provocación oral con alubia blanca. Resultados: El prick-by-prick con alubia blanca fue positivo en el paciente y negativo en 10 controles. La determinación de IgE específica fue positiva para alubia blanca y alubia verde. El paciente desarrolló angioedema tras provocación oral con alubia blanca. Conclusión: Hemos demostrado una reacción de hipersensibilidad tipo I a alubia blanca en un niño de 7 años por pruebas cutáneas, IgE específica y provocación oral
