Los inicios de la radiología en Málaga / The beginnings of radiology in Malaga

El descubrimiento de los rayos X se conoció en Málaga el 2 de marzo de 1896 mediante la prensa local, que recoge además diversas noticias sobre el uso de los rayos X y evidencias del uso literario del descubrimiento de Roentgen por periodistas y escritores de esa época. Entre ellas, destaca la existencia de un periódico administrativo y de intereses generales denominado Los Rayos X. Los primeros equipos de rayos X se instalaron progresivamente en los hospitales de la época, y la primera instalación en un gabinete médico privado data de 1900. En Málaga, la asimilación y evolución del uso diagnóstico y terapéutico de la radiología fue lenta y con peculiaridades determinadas por las circunstancias sociales, económicas y culturales de la época. La presencia de médicos relevantes y con voluntad de superación consiguió elevar la práctica médica a un nivel similar al de otras ciudades de parecidas características

[Long-term renal function in Wilms tumor survivors]. / Función renal a largo plazo en supervivientes de tumor de Wilms.

OBJETIVE: To evaluate long-term renal function and morbimortality in non-syndromic Wilms tumor (WT) survivors. METHODS: Retrospective study about WT patients treated in 1993-2017, according to SIOP protocols. Mortality, glomerular filtration rate (GFR), prevalence of hypertension and requirement of dialysis and renal transplant were evaluated. Chronic kidney disease (CKD) was defined as GFR <90 ml/min/1.73 m2. RESULTS: Thirty-nine children were treated in the 25 analyzed years. Median time of follow-up was 6 years (0.5-21 years). 48% (19 patients) debuted with stage I or II. Four cases had high-grade histo-logy. Mortality rate was 10%. GFR data were found in 37 patients. Chronic kidney disease (grade I-II) turned up in 6 patients (16%). No patient required renal replacement therapy or renal transplant. 16% of patients developed CKD in both unilateral and bilateral WT, (p>0.05); OR 1.04 (IC 95% 0.09-10.9). Identical results were obtained comparing patients treated with or without radiotherapy (16%). Children with stage I-III had CKD in 11% vs. 40% of patients with stage IV (p=0.12); OR 5.3 (IC 95% 0.61-45). None of them presented hypertension in addition. CONCLUSIONS: In the current study the prevalence of CKD was low but not negligible, although no patients required renal replacement therapy or renal transplant. Bilateral renal involvement and radiotherapy were not associated with CKD development. Metastatic disease determines a higher risk of CKD.

OBJETIVOS: Evaluar la función renal y la morbimortalidad a largo plazo, en supervivientes de tumor de Wilms (TW) no sindrómico. MATERIAL Y METODOS: Estudio retrospectivo de pacientes con TW entre 1993-2017 tratados según protocolos SIOP. Evaluamos mortalidad, filtrado glomerular (FG), prevalencia de hipertensión arterial (HTA), necesidad de diálisis y trasplante renal. Se definió enfermedad renal crónica (ERC) como FG <90 ml/min/1,73 m2. RESULTADOS: En los 25 años analizados se trataron 39 pacientes con edad media diagnóstica de 3,6 años (0,3-11 años). Mediana de seguimiento 6 años (0,5-21 años). El 48% (19 pacientes) debutaron con estadio I o II. Cuatro pacientes presentaron histología de alto riesgo (10%). La mortalidad fue del 10%. El 16% (6 pacientes) desarrolló ERC (grados I-II). Ningún paciente precisó terapia renal sustitutoria (TRS) o trasplante. La presencia de ERC tanto en enfermedad unilateral como bilateral fue del 16%, p>0,05; OR 1,04 (IC 95% 0,09-10,9). Se obtuvieron idénticos resultados (16%) comparando pacientes que recibieron radioterapia frente a aquellos que no. Los pacientes en estadio I, II y III presentaron una prevalencia de ERC del 11% vs. 40% en estadio IV (p=0,12); OR 5,3 (IC 95% 0,61-45). Ningún paciente asoció HTA crónica. CONCLUSIONES: En el presente estudio la prevalencia de ERC en supervivientes de TW no sindrómico es baja pero no desdeñable, aunque ninguno precisó trasplante renal o TRS. La presencia de enfermedad bilateral y la radioterapia no se asociaron al desarrollo de ERC. La enfermedad metastásica condiciona un riesgo mayor de ERC.

Calidad de vida en pacientes tratados con metadona: el WHOQOL-BREF, estudio psicométrico y resultados de aplicación / Quality of life in patients treated with methadone: The WHOQOLBREF, psychometric study and application results

Objetivo. De entre los muchos instrumentos propuestos para medir la calidad de vida de los pacientes con adicción a opiáceos tratados con metadona el WHOQOL-BREF, propuesto por la World Health Organization, es el que más se utiliza en la actualidad. Este trabajo pretende estudiar la fiabilidad y la validez de constructo de la prueba, aplicada a una muestra amplia y representativa de pacientes, y comparar los resultados con los datos disponibles para población general en España. Se reclutó una muestra de 523 sujetos que se encontraban en tratamiento con metadona, en Madrid y Extremadura. Se efectuó un análisis factorial confirmatorio para probar la estructura teóricamente propuesta y, seguidamente, un análisis paralelo optimizado para conocer el número más adecuado de componentes de la prueba. Los resultados muestran que la prueba presenta sólidos valores de consistencia interna, tanto a nivel del ítem como de las escalas. La estructura tetradimensional teórica se confirma en la muestra con adecuados indicadores de ajuste, aunque también se obtienen serios argumentos para considerar su unidimensionalidad. Se estudió la relación estructural entre los cuatro dominios. El WHOQOL-BREF se muestra como una prueba fiable y válida para su uso en pacientes tratados con metadona, proporcionando una medida multidimensional de la calidad de vida percibida, que incluye factores sociales y ambientales ausentes en otros instrumentos, que son de enorme importancia en el tratamiento de los problemas adictivos

The most commonly instrument used to measure quality of life in patients with addictive behaviors is the WHOQOL-BREF, developed by the World Health Organization. No studies have been found to explore the psychometric properties in Spanish clinical samples. This paper aims to study their reliability as well as the construct validity in a representative sample of patients and comparing the results to the data available for the general population in Spain. A sample was recruited comprised of 523 subjects who were undergoing treatment with methadone in Madrid and Extremadura. A confirmatory factor analysis was completed to test the theoretically proposed structure and then an optimized-parallel analysis was done to establish the most adequate number of components. The result offers solid values for internal consistency both as concerns the items and the scales. The theoretical tetra-dimensional structure is confirmed in the sample although serious arguments are also found for considering its onedimensionality. The structural relationship between the four domains was studied. The WHOQOL-BREF proves to be a reliable and valid test for use on patients treated with methadone, providing a multi-dimensional measure of perceived quality of life that includes social and environmental factors of great importance in treating addiction problems

Trends and risk factors of hepatitis A in Catalonia after the introduction of a hepatitis A+B vaccination programme.

At the end of 1998, universal hepatitis A+B vaccination of 12 year olds was introduced in Catalonia. The aim was to examine trends in hepatitis A during 2005-2015 and assess risk factors by age group. We carried out an observational epidemiological study of the incidence and risk factors of hepatitis A reported to the surveillance system. Information on exposure was recorded for each case for the 2-6 weeks before symptom onset. Spearman's coefficient was used to evaluate the trends of rates. The chi-square test was used to compare categorical. We studied 2621 hepatitis A cases; the age mean was 26.6 years (SD=18.2), and >50% of cases were in the 20-49 years age group. The incidence decreased from 3.28/100 000 in 2005 to 1.50/100 000 in 2015. The rate for women decreased over time (P = .008), but the reduction was not significant in men (P = .234). Men consistently had higher rates than women with the biggest difference being in the 20-34 years age group (rate 8.8 vs 2.8). The greatest risk factor was travel to an endemic country (42.1%) in the 0-19 years age group and male-to-male sexual contact (18.6%) in the 20-49 years age group. The case fatality rate in adults aged >49 years was 0.4%. In conclusion, the vaccination programme of preadolescents resulted in a reduction in hepatitis A cases. However, a significant amount of cases still appear in immigrants and men who have sex with men. Hepatitis A in adults is an emerging health problem that will require new strategies.

RESUMEN Objetivo: Identificar el nivel de autoeficacia percibida y su relación con variables biodemográficas y psicosociales en adultos mayores. Material y método: Diseño descriptivo correlacional, muestreo aleatorio estratificado, de 754 adultos mayores inscritos en centros de salud de Antofagasta, Chile. Mediciones: antecedentes socio-demográficos, estado de salud, autoeficacia percibida; Examen de Funcionalidad del Adulto Mayor (parte B); Calidad de vida relacionada con la salud, medida con el Cuestionario SF-12 y Fragilidad. Resultados: 61,4% de mujeres versus 38,6% de hombres; la edad osciló entre los 65 y 90 años, con una media de 73 años (DE= 6,0); el 78,9% declaró de dos a seis años de estudios. Los antecedentes mórbidos presentados con mayor frecuencia fueron: Hipertensión arterial, Dislipidemia y Diabetes Mellitus. El 86,3% no presentó depresión. La autopercepción de salud calificada como "excelente a buena" alcanzó sobre el 60%. La autoeficacia fue percibida alta en un 68,3%. La calidad de vida relacionada con salud global fue percibida con satisfacción por el 55,6%. Los niveles de fragilidad alcanzaron el 73,5%. El 59,3% de los adultos mayores fueron clasificados como autovalente sin riesgo. Se encontraron diferencias estadísticamente significativas entre las categorías de autoeficacia y temor a caerse, estado nutricional, depresión, calidad de vida relacionada con salud y la autopercepción de salud. Conclusión: Se identificó y relacionó una alta autoeficacia percibida, tanto en variables biodemográficas como psicosociales, que podría ser un factor facilitador para promover un envejecimiento activo.

ABSTRACT Objective: Identify the level of perceived self-efficacy and its relationship with biodemographic and psychosocial variables in older adults. Material and method: Descriptive correlational design, stratified random sampling, of 754 older adults registered in health centers of Antofagasta, Chile. Measurements : sociodemographic background, health status, perceived self-efficacy; Functional Test of the Elderly (part B); Quality of life related to health, measured with the SF-12 and Fragility Questionnaire. Results: 61.4% of participants were women and 38.6% were men; the ages ranged between 65 and 90 years, with an average of 73 years (SD = 6.0); 78.9% declared between two and six years of schooling. The morbid antecedents most frequently presented were: Arterial Hypertension, Dyslipidemia and Diabetes Mellitus. 86.3% did not present depression. Self-rated health rated "excellent to good" reached over 60%. Self-efficacy was perceived as high by 68.3% of participants. A 55.6% was satisfied with their quality of life in relation to global health. Fragility levels reached 73.5%. 59.3% of older adults were classified as self-reliant without risk. Statistically significant differences were found between the categories of self-efficacy and fear of falling, nutritional status, depression, quality of life related to health and self-perception of health. Conclusion: A high perceived self-efficacy was identified and related, both in biodemographic and psychosocial variables, which could be a facilitating factor to promote active aging.

Rentabilidad diagnóstica de la resonancia magnética lumbosacra solicitada desde las consultas de urología pediátrica / Diagnostic yield of lumbosacral magnetic resonance imaging requested by paediatric urology consultations

Objetivos: En series históricas, la rentabilidad diagnóstica de la resonancia magnética lumbosacra para descartar disrafismo espinal oculto (o mielodisplasia oculta), solicitada desde urología pediátrica oscila entre el 2 y 15%. El objetivo del estudio es definir nuestra rentabilidad en niños con síntomas miccionales, y definir variables que aumenten la posibilidad de encontrar disrafismo espinal oculto. Pacientes y métodos: Selección de pacientes con disfunciones miccionales a los que se solicitó resonancia magnética desde las consultas de urología pediátrica, por persistencia de síntomas tras tratamiento, disfunción de vaciado, o por otros hallazgos clínicos o urodinámicos. Se analizaron variables clínicas (ITU, fugas diurnas, enuresis, disfunción de vaciado, urgencia, ecografía renal, radiografía lumbosacra, antecedentes de retención aguda de orina, estigmas cutáneos, mialgias) y urodinámicas (hiperactividad o arreflexia, micción disfuncional, patrón interrumpido, valor de acomodación y flujo máximo). Análisis univariante con SPSS 20.0 Resultados: Analizamos a 21 pacientes en el periodo 2011-2015. Mediana de edad: 6 años (3-10). Tres pacientes (14,3%) presentaron disrafismo espinal oculto: un lipoma raquídeo, un filum lipomatoso y un síndrome de regresión caudal con estenosis de canal. Las variables con diferencia estadísticamente significativa fueron las mialgias y el antecedente de retención aguda de orina (66,7 vs. 5,6%; p = 0,04; OR = 34; IC95%: 1,5-781 para ambas variables). Conclusiones: La rentabilidad diagnóstica de la resonancia magnética solicitada a niños con disfunciones miccionales sin estigmas cutáneos ni alteraciones neuroortopédicas es baja, aunque no desdeñable. En este grupo, los pacientes con antecedentes de retención aguda de orina y/dolor muscular (dolor, «calambres») pueden presentar una rentabilidad diagnóstica o valor predictivo positivo mayor

Objectives: In the historical series, the diagnostic yield of lumbosacral magnetic resonance imaging to rule out occult spinal dysraphism (or occult myelodysplasia), requested by paediatric urology, ranged from 2% to 15%. The aim of this study was to define our cost-effectiveness in children with urinary symptoms and to define endpoints that increase the possibility of finding occult spinal dysraphism. Patients and methods: A screening was conducted on patients with urinary dysfunction for whom an magnetic resonance imaging was requested by the paediatric urology clinic, for persistent symptoms after treatment, voiding dysfunction or other clinical or urodynamic findings. We analysed clinical (UTI, daytime leaks, enuresis, voiding dysfunction, urgency, renal ultrasonography, lumbosacral radiography, history of acute urine retention, skin stigma and myalgia) and urodynamic endpoints (hyperactivity or areflexia, voiding dysfunction, interrupted pattern, accommodation value and maximum flow). A univariate analysis was conducted with SPSS 20.0. Results: We analysed 21 patients during the period 2011-2015. The median age was 6 years (3-10). Three patients (14.3%) had occult spinal dysraphism: one spinal lipoma, one filum lipomatosus and one caudal regression syndrome with channel stenosis. The endpoints with statistically significant differences were the myalgias and the history of acute urine retention (66.7% vs. 5.6%, P = .04; OR = 34; 95%CI: 1.5-781 for both endpoints). Conclusions: The diagnostic yield of magnetic resonance imaging requested for children with urinary dysfunctions without skin stigma or neuro-orthopaedic abnormalities is low, although nonnegligible. In this group, the patients with a history of acute urine retention and muscle pain (pain, «cramps») can experience a greater diagnostic yield or positive predictive value

[Long-term results of hypospadias surgery. Urinary and sexual function, and psychological impact]. / Resultados a largo plazo de la cirugía de hipospadias. Función urinaria, sexual e impacto psicológico.

OBJECTIVES: To determine the current status of the patients operated on for hypospadias in our region, in order to adapt the surgical technique to their real needs. MATERIAL AND METHODS: A descriptive and observational study. Interviews were conducted with hypospadias surgery patients in our hospital between 1976 and 1996, focusing on their urinary and sexual function and psychological impact. We performed a descriptive statistical analysis and comparisons between types of hypospadias (SPSSv19). RESULTS: 566 patients were operated on for hypospadias during the study period, interviewing 100 aged between 18 and 40 years. The 73% were distal and 27% proximal. Of all patients, 30% do not have an orthotopic meatus, 10% have fistula, 18% have some degree of stenosis and 52% have penile curvature. The 13% feel to have had disadvantages in their life. They consider they have a different penis in: size (19%), glans shape (17%), curvature (14%), scars (10%) and lowest hole (7%). Sexual satisfaction was valued at 8.9 on a scale of 1 to 10, with no differences between the types of hypospadias. Proximal hypospadias patients have more ejaculation problems: 42% versus 11% in distal hypospadias. The 68% of the proximal ones would like to improve compared to 20% of the distal in: appearance (17%), size (11%) and way to urinate (11%). CONCLUSIONS: Anatomic abnormalities are maintained but the aspects that values the adult patient differ from those persecuted by practiced surgeries. A significant percentage of patients would try to get another surgery. Keeping the size of the penis and natural appearance of the glans should be a priority in hypospadias surgery.

OBJETIVOS: Conocer el estado actual de los pacientes intervenidos por hipospadias en nuestra región, para adaptar la técnica quirúrgica a sus necesidades reales. MATERIAL Y METODOS: Estudio descriptivo y observacional. Se entrevistó a pacientes intervenidos de hipospadias en nuestro hospital entre 1976 y 1996, incidiendo en su función urinaria, sexual e impacto psicológico. Realizamos análisis estadístico descriptivo y comparaciones entre tipos de hipospadias (SPSSv19). RESULTADOS: 566 pacientes fueron intervenidos de hipospadias en el período estudiado, entrevistándose a 100, con edades entre 18 y 40 años. El 73% fueron distales y 27% proximales. En el 30% el meato no es ortotópico, 10% presenta fístula, 18% presenta algún grado de estenosis y 52% presenta curvatura. El 13% siente haber tenido desventajas en su vida. Consideran su pene diferente en: tamaño (19%), forma glande (17%), curvatura (14%), cicatrices (10%) y orificio más bajo (7%). La satisfacción sexual fue valorada en 8,9 en una escala del 1 al 10, sin diferencias entre los tipos de hipospadias. Los proximales presentan mayores problemas de eyaculación: 42% frente al 11% de los distales. El 68% de los proximales desearían mejorar frente al 20% de los distales, en apariencia (17%), tamaño (11%) y forma de orinar (11%). CONCLUSIONES: Se mantienen alteraciones anatómicas pero los aspectos que más valora el paciente adulto difieren de los perseguidos en las cirugías que se practicaban. Un porcentaje importante de pacientes se reoperaría de nuevo. Mantener el tamaño del pene y aspecto natural del glande debe ser un objetivo prioritario durante la cirugía de hipospadias.

Three patients (14.3%) had occult spinal dysraphism: one spinal lipoma, one filum lipomatosus and one caudal regression syndrome with channel stenosis. The endpoints with statistically significant differences were the myalgias and the history of acute urine retention (66.7% vs. 5.6%, P=.04; OR= 34; 95%CI: 1.5-781 for both endpoints). CONCLUSIONS: The diagnostic yield of magnetic resonance imaging requested for children with urinary dysfunctions without skin stigma or neuro-orthopaedic abnormalities is low, although nonnegligible. In this group, the patients with a history of acute urine retention and muscle pain (pain, «cramps¼) can experience a greater diagnostic yield or positive predictive value.

Biofeedback animado para el tratamiento de la micción disfuncional / Animated biofeedback for the dysfunctional voiding syndrome

Objetivos. Se pretende analizar resultado clínico y electromiográfico del tratamiento de la micción disfuncional (MD) con Biofeedback (Bfb) animado. Además, se estudia si existen variables clínicas o electromiográficas asociadas a mayor tasa de éxito. Pacientes y métodos. Se realizó corte transversal de pacientes con MD, que en 2010- 2015 siguieron programa de Bfb animado. El control post-tratamiento se realizó con Uroflujometría más Electromiografía y cuestionario validado. Se excluyeron los pacientes con mielodisplasia, malformaciones anatómicas, y a los que recibieron menos de 3 sesiones. Las variables clínicas estudiadas fueron: edad, número de sesiones, fugas diurnas, enuresis nocturna, estreñimiento, ITU, RVU. Las flujométricas fueron: morfología de curvas, electromiograma, flujos, y residuo postmiccional (RPM) elevado. Resultados. De 37 pacientes que recibieron Bfb, se seleccionaron 27 niñas que cumplieron criterios de inclusión. Edad media: 7,8 años (DE: 2,5). Doce (44%) presentaron hiperactividad del detrusor asociado a la MD. De manera global, todos los parámetros clínicos y flujométricos mejoraron. Clínicamente 33,5% presentó resolución completa de síntomas y el 37% mejoraron (desaparecieron más del 50% de los síntomas según criterios ICCS). El 29% no presentó mejoría. Electromiográficamente el 74% logró flujometrías normales. El estreñimiento al inicio del estudio se asocia a tasas menores de éxito (curación: 13 vs. 58%, p= 0,019; curación + mejoría: 60% vs. 83% p > 0,05). La ausencia de RPM al final del estudio se relacionó con la mejoría clínica (curación: 66,7% vs. 0%, p= 0,012; curación + mejoría: 89% vs. 60%, p > 0,05). Conclusiones. El Bfb en la micción disfuncional proporciona tasas de curación/mejoría clínica y de resolución electromiográfica del 69 y 74%, respectivamente. La ausencia de estreñimiento se asocia a mayores tasas de éxito. La persistencia de clínica se relaciona con RPM elevado post-tratamiento

Objectives. To analyze clinical and electromyographic treatment outcome of dysfunctional voiding (DV) with animated Biofeedback (Bfb). Clinical or electromyographic variables associated with higher success rate were checked. Patients and Methods. Cross-sectional study of patients with DV, that in 2010- 2015 followed animated Bfb program. Efficacy was measured with Uroflowmetry, Electromyography (EMG) and validated clinical questionnaire. Inclusion criteria: no myelodysplasia, no anatomical malformations and a minumin of 3 Bfb sessions. Clinical variables: age, number of sessions, daytime leaks, nocturnal enuresis, constipation, UTI, VUR. Flow measurement variables: morphology of curves, electromyogram, flows, and elevated post void residual (PVR). Results. Of 37 patients who received Bfb, 27 girls who met inclusion criteria were selected. Mean age: 7.8 years (2.5). Twelve (44%) had detrusor overactivity on urodynamics concomitantly. Globally, all clinical and flowmetry parameters improved. Clinically 33.5% had complete resolution of symptoms, 37% improved (> 50% of symptoms according to criteria ICCS) and 29% had no improvement. In EMG, 74% achieved normal perineal relaxation. Constipation at baseline is associated with lower rates of success (cure: 13 vs. 58%, p = 0.019; cure + improvement: 60% vs. 83% p> 0.05). The absence of RPM at the end of the study was associated with clinical improvement (cure: 66.7% vs. 0%, p = 0.012; cure + improvement: 89% vs. 60%, p> 0.05). Conclusions. Bfb in DV provides cure or improvement and electromyographic resolution are 69 and 74% respectively. The absence of constipation is associated with higher success rates. The High RPM correlates with persistence of clinics

Lamellipodin promotes invasive 3D cancer cell migration via regulated interactions with Ena/VASP and SCAR/WAVE.

Cancer invasion is a hallmark of metastasis. The mesenchymal mode of cancer cell invasion is mediated by elongated membrane protrusions driven by the assembly of branched F-actin networks. How deregulation of actin regulators promotes cancer cell invasion is still enigmatic. We report that increased expression and membrane localization of the actin regulator Lamellipodin correlate with reduced metastasis-free survival and poor prognosis in breast cancer patients. In agreement, we find that Lamellipodin depletion reduced lung metastasis in an orthotopic mouse breast cancer model. Invasive 3D cancer cell migration as well as invadopodia formation and matrix degradation was impaired upon Lamellipodin depletion. Mechanistically, we show that Lamellipodin promotes invasive 3D cancer cell migration via both actin-elongating Ena/VASP proteins and the Scar/WAVE complex, which stimulates actin branching. In contrast, Lamellipodin interaction with Scar/WAVE but not with Ena/VASP is required for random 2D cell migration. We identified a phosphorylation-dependent mechanism that regulates selective recruitment of these effectors to Lamellipodin: Abl-mediated Lamellipodin phosphorylation promotes its association with both Scar/WAVE and Ena/VASP, whereas Src-dependent phosphorylation enhances binding to Scar/WAVE but not to Ena/VASP. Through these selective, regulated interactions Lamellipodin mediates directional sensing of epidermal growth factor (EGF) gradients and invasive 3D migration of breast cancer cells. Our findings imply that increased Lamellipodin levels enhance Ena/VASP and Scar/WAVE activities at the plasma membrane to promote 3D invasion and metastasis.

Clinical characteristics and pertussis costs in cases reported to epidemiological services and cases detected in household contacts in Catalonia (Spain).

PURPOSE: To assess the clinical characteristics and direct health costs associated with pertussis cases reported to and confirmed by epidemiological services and cases detected among household contacts in Catalonia (Spain) in 2012-2013. METHODS: All pertussis cases confirmed by the epidemiological services (n = 641) and all cases detected among the household contacts (n = 422) were included in the study. The chi-square test and odds ratios were used to compare percentages and the t-test was used to compare mean pertussis costs, with p < 0.05 being considered statistically significant. RESULTS: Cases reported to epidemiological services had a higher percentage of hospitalizations (OR = 32.2, p < 0.001) and severe disease (OR = 27.7, p < 0.001) than cases detected among the household contacts. The total health costs associated with pertussis cases were €871,648, €799,704 (92 %) for cases reported to epidemiological services and €71,944 (8 %) for cases detected among the household contacts. Total treatment, detection, and quimiprophylaxis costs were € 809,702, € 44,312, and € 17,635, representing 92.5 %, 5.5 %, and 2 % of total pertussis costs respectively. The mean costs were significantly higher (p < 0.001) in cases reported to epidemiological services than in cases detected among the household contacts, for all cases (€1248 vs €170), and for severe (€4546 vs €1073), moderate (€204 vs €165), and mild (€153 vs €133) disease. CONCLUSIONS: The burden of pertussis in Catalonia was high in terms of health costs, especially in infants aged less than 1 year. Active epidemiological surveillance activities could prevent pertussis transmisison and reduce pertussis costs.

Oxidant/antioxidant effects of chronic exposure to predator odor in prefrontal cortex, amygdala, and hypothalamus.

The incidence of anxiety-related diseases is increasing these days, hence there is a need to understand the mechanisms that underlie its nature and consequences. It is known that limbic structures, mainly the prefrontal cortex and amygdala, are involved in the processing of anxiety, and that projections from prefrontal cortex and amygdala can induce activity of the hypothalamic-pituitary-adrenal axis with consequent cardiovascular changes, increase in oxygen consumption, and ROS production. The compensatory reaction can include increased antioxidant enzymes activities, overexpression of antioxidant enzymes, and genetic shifts that could include the activation of antioxidant genes. The main objective of this study was to evaluate the oxidant/antioxidant effect that chronic anxiogenic stress exposure can have in prefrontal cortex, amygdala, and hypothalamus by exposition to predator odor. Results showed (a) sensitization of the HPA axis response, (b) an enzymatic phase 1 and 2 antioxidant response to oxidative stress in amygdala, (c) an antioxidant stability without elevation of oxidative markers in prefrontal cortex, (d) an elevation in phase 1 antioxidant response in hypothalamus. Chronic exposure to predator odor has an impact in the metabolic REDOX state in amygdala, prefrontal cortex, and hypothalamus, with oxidative stress being prevalent in amygdala as this is the principal structure responsible for the management of anxiety.

A modified device to facilitate flow measurements during voiding cystometry studies in infants.

INTRODUCTION: Urodynamic studies (UDS) in infants are traditionally hampered by technique and flow collection; both are difficult and have not yet been standardized. METHODS: A very simple device has been developed to collect urine during the voiding phase in UDS. It is based on a urine-collection adhesive bag, which is connected to a tube that conducts the urine to a flowmeter. RESULTS: Eleven infants (4-23 months) were selected and a complete UDS was performed on all of them. A diagnosis was obtained for all of the infants. DISCUSSION: This device is easily available in every pediatric clinic; it is also disposable and inexpensive. It enables UDS in infants to be complete and achievable.

Indicadores de fragilidad en adultos mayores del sistema público de salud de la ciudad de Antofagasta / Rates of frailty among older people ascribed to chilean primary care clinics

Background: Frailty is not universal among older people but increases the risk of dependence. Aim: To assess frailty among older people and its relationship with biological, psychological and social factors. Material and Methods: Seven hundred fifty four older people aged 73 ± 6 years (61% females), attending a public primary care were assessed. Frailty was defined according to Fried criteria that considers inexplicable weight loss, tiredness, muscle weakness and lack of physical activity. Results: Absence of frailty, pre-frailty and frailty was found in 26, 69 and 5% of participants, respectively. Significant differences between frailty groups were observed for age, gender, years of studies, minimental and self-efficacy scores. Among participants defined as being in a pre-frail condition, 59% were non-disabled without risk and 41% non-disabled in risk, according to the functional assessment for older people used in Chilean primary care clinics. Conclusions: Frailty among older people is associated with increasing age, education, cognitive status and self-efficacy.

Quistes mesentéricos en la edad pediátrica: ¿qué son en realidad? / Mesenteric cysts in children

OBJETIVOS: Los quistes mesentéricos (QM) son tumores quísticos benignos, integrados en el tejido del mesenterio o del epiplón. Hemos revisado los casos de QM no enterógeno. MATERIAL Y MÉTODOS: Revisión de historias clínicas y biopsias de los casos intervenidos de QM en el periodo 2002-2012. RESULTADOS: Encontramos a 7 pacientes, edad media de 5,3 a˜nos (rango 3-11). El diagnóstico fue ecográfico en todos, salvo en uno. Todos presentaron dolor abdominal; 5 (71,4%) vómitos; 4 (57%) distensión abdominal; 3 (42,8%) fiebre; ninguno presentó obstrucción abdominal completa, aunque 2 pacientes (28,6%) presentaron suboclusión. El quiste fue pediculado o sésil en todos menos en uno, que englobaba raíz de mesocolon y retroperitoneo. La histología de todos ellos reveló malformación linfática. No hubo recurrencias. CONCLUSIONES: Los quistes mesentéricos en niños son en su mayoría malformaciones linfáticas del mesenterio, con clínica muy variada. En el 50-60% están integrados en el mesenterio y requieren resección del asa afectada y anastomosis

OBJECTIVES: Mesenteric cysts (MC) are benign cystic tumors that grow within mesentery or omentum tissue. We have reviewed the cases of MC reported and operated on in our centre. MATERIAL AND METHODS: Retrospective review of clinical records of MC cases during the period 2002-2012 RESULTS: A total of 7 patients were found. Mean age was 5.3 years (range 3-11). Abdominal ultrasound was the diagnostic tool in all cases, except for one, which was diagnosed during laparotomy. All presented abdominal pain, 5 (71.4%) vomiting, 4 (57%) gross abdominal distension, 3 (42.8%) fever, and none presented complete abdominal obstruction, although 2 patients (28.6%) had slight sub-occlusion symptoms. All MC were pedicled or sesil, except for our last case, which extended into the retroperitoneum. All specimens were reported as Limphatic Malformation. None recurred. CONCLUSIONS: MC in children are mostly Lymphatic Malformations of mesentery or omentum origin, and clinical presentation varies from chronic abdominal pain to sudden-onset peritonitis or volvulus. About 50-60% require intestinal resection and anastomosis
