RESUMO

Objetivos: Evaluar la eficacia y la eficiencia de la biopsia prostática sistemática (BPS) y la biopsia de próstata por fusión cognitiva (BPFC) para diagnosticar el cáncer de próstata (CaP) y el CaP significativo (CaPs) y analizar si la BPFC podría reemplazar con seguridad a la BPS. Material y métodos: Una cohorte de 314 hombres consecutivos que tenían PI-RADS ≥2 en una biopsia previa 3T resonancia magnética multiparamétrica se sometieron prospectivamente a BPFC ecográfica transrectal (dos núcleos por área sospechosa hasta un máximo de tres áreas) y una BPS de 12 núcleos periféricos. Se consideró CaPs cuando el grado de la OMS fue superior a 2 (Gleason 4 + 3 o superior). Resultados: Se diagnosticó CaP en 133 pacientes (42,4%), de los que 83 (62,4%) fueron CaPs. La BPS detectó CaP en 114 hombres (85,7%) y BPFC en 103 (77,4%), p < 0,001. La BPS detectó CaPs en 64 hombres (77,1%) y BPFC en 71 (85,5%), p < 0,001. En 52 de los 81 hombres (64,2%) se detectó CaPs en BPS y BPFC. En 19 hombres solo se detectó CaPs en BPFC (23,5%), mientras que en 10 solo se detectó en BPS (12,3%). Se necesitaron 33,1 núcleos para diagnosticar un CaP en BPS y 8,5 en BPFC, p < 0,001. 58,9 núcleos fueron necesarios para diagnosticar un CaPs en BPS y 12,4 en BPFC, p < 0,001. Conclusiones: Las BPFC son más efectivas y también más eficientes que las BPS para detectar CaPs. Sin embargo, las BPFC aún no pueden reemplazar las BPS de manera segura porque no pueden detectar hasta el 15% de los CaPs


Objectives: To evaluate the efficacy and efficiency of systematic prostatic biopsy (SPB) and cognitive fusion PB (CFPB) to diagnose prostate cancer (PCa) and significant PCa (SPCa), and to analyse if CFPB could safely replace SPB. Material and methods: A cohort of 314 consecutive men having PI-RADS ≥ 2 in a pre-biopsy 3T mp-MRI were prospectively subjected to trans-rectal ultrasound CFPB (two cores per suspicious area until a maximum of three areas) and a 12 peripheral core SPB. SPCa was considered when the WHO grade was higher than 2 (Gleason 4+3 or higher). Results: PCa was diagnosed in 133 patients (42.4%), being 83 (62.4%) SPCa. SPB detected PCa in 114 men (85.7%) while CFPB in 103 (77.4%), P < .001. SPB detected SPCa in 64 men (77.1%) while CFPB in 71 (85.5%), P < .001. In 52 of the 81 men (64.2%) SPCa was detected in SPB and CFPB. In 19 men SPCa was only detected in CFPB (23.5%) while in 10, it was only detected in SPB (12.3%). 33.1 cores were needed to diagnose one PCa in SPB while 8.5 in CFPB, P < .001. 58.9 cores were needed to diagnose one SPCa in SPB, while 12.4 in CFPB, P < .001. Conclusions: CFPB are more effective and also more efficient than SPBs in detecting SPCa. However, CFPBs still can’t safely replace SPBs because they are not able to detect up to 15% of SPCa

RESUMO

Purpose. Recently neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been reported to be inflammatory parameters that confer poorer outcome in metastatic castration-resistant prostate cancer (mCPRPC). However, these ratios have not been analyzed in patients treated with abiraterone acetate. We explored the relationship between different values of PLR and NLR and survival in mCPRCP treated with abiraterone and their possible relation with a prostate specific antigen (PSA) response. Methods. We retrospectively analyzed 101 patients with mCRPC treated with abiraterone from January of 2012 to November of 2015 in two different hospitals. A cut-off value of 5 for NLR and 150 for PLR were used to compare survival by Kaplan-Meier method. Moreover, an association between these cut-off values and the PSA response was analyzed by a χ2 test. Results. In the case of NLR, the median DFS were 12, 1 months for NLR <5 and 7 months for NLR ≥5, p = 0.061. The median OS were 23.9 months for NLR <5 and 16.3 months for NLR ≥5, p = 0.046. In the case of PLR, the median DFS were 11.8 months for PLR <150 and 10.6 months for PLR ≥150, p = 0.549. The median OS were 27.4 months for PLR <150 and 15.9 months for PLR ≥150, p = 0.005. It was not observed a correlation between the different cut-off values of PLR or NLR and a PSA response ≥25% (p = 0.31). Conclusions. It is shown a better prognostic relationship between PLR and NLR low values and OS that is statistically significant in mCPRC patients treated with abiraterone. Furthermore, it was not shown a relation between PLR and NLR values and PSA response (AU)

RESUMO

La escombroidosis es una causa frecuente de intoxicación alimentaria a nivel mundial que se debe a la ingesta de pescado azul contaminado con bacterias que inducen la formación de grandes cantidades de histamina. Clínicamente se manifiesta sobre todo a nivel cutáneo, en forma de flushing descendente y/o rash eritemato-urticariforme facial y en el tronco superior. Aunque habitualmente tiene un curso autolimitado y benigno, pueden existir casos de compromiso vascular, broncoespasmo y arritmias. Es importante hacer un correcto diagnóstico diferencial, entre otros con la alergia al pescado. El tratamiento se basa en la administración de antihistamínicos orales. Lo más importante es su prevención mediante una correcta refrigeración del pescado. Este trabajo es una revisión práctica de la escombroidosis orientada para su uso por el dermatólogo


Scombroid poisoning is a common cause of food poisoning worldwide. It is caused by ingestion of oily fish contaminated with bacteria that trigger the formation of high concentrations of histamine. Scombroid poisoning manifests mainly as a skin complaint (flushing that spreads downward and/or an erythematous urticarial rash affecting the face and upper trunk). Although the clinical course is usually self-limiting and benign, vascular compromise, bronchospasm, and arrhythmias have been described. It is important to establish a differential diagnosis that includes conditions such as fish allergy. Oral antihistamines are the mainstay of treatment. Scombroid poisoning is best prevented by refrigerating fish properly. The practical review of scombroid poisoning provided here is intended for dermatologists

RESUMO

Objetivos: Presentar un registro nacional de pacientes con cáncer de próstata seguidos mediante vigilancia activa, con la intención de testar la hipótesis de que la mortalidad cáncer específica en pacientes de muy bajo riesgo y riesgo bajo es menor del 5% a 15 años. Material y métodos: Estudio multicéntrico observacional (AEU-PIEM/2014/0001) promovido por la Asociación Española de Urología mediante su plataforma para estudios multicéntricos, en donde los criterios de inclusión clínico-patológicos son: cT1a-cT3a, PSA ≤ 20 ng/ml, biopsia (Bx) inicial mínima de 10 cilindros, número de cilindros afectos ≤ 3, Gleason 1.° = 3 y Gleason 2.° ≤ 4, y volumen prostático conocido (en cc). No se establece un seguimiento unificado para todos los centros reclutadores, y sí una encuesta en la que se reflejen las características del seguimiento en función de unos parámetros tangibles que permitan su comparabilidad. Con la misma filosofía de flexibilidad no se considera obligada la utilización de determinados biomarcadores o de RMN mutiparamétrica para su inclusión. Resultados: Se presentan las características y posibilidades del registro a modo descriptivo y los resultados preliminares de 324 pacientes incluidos en sus primeros 5 meses de funcionamiento por 15 centros reclutadores. De la misma forma se describen las variables clínico-patológicas, biomarcadores, técnicas de radiodiagnóstico y cuestionarios de calidad de vida contemplados por la base de datos, así como las posibilidades de seguimiento indefinido y abierto a cualquier tratamiento activo reconocido en guías clínicas. Conclusiones: La AEU-PIEM/2014/0001 constituye una herramienta extremadamente útil a todos los urólogos españoles para la investigación clínica multicéntrica, y sin duda permitirá la difusión de la vigilancia activa entre nuestros pacientes de una forma más coordinada, permitiendo mantener las ventajas del screeningoportunista optimizado en cáncer de próstata sin incurrir en el sobretratamiento


Objectives: To present a National Registry of patients with prostate cancer as monitored through active surveillance, with the intention of testing the hypothesis that cancer-specific mortality in very low-risk and low-risk patients is less than 5% at 15 years. Material and methods: A multicentre observational study (AEU-PIEM/2014/0001) sponsored by the Spanish Association of Urology was conducted using their platform for multicentre studies. The clinical-pathological inclusion criteria were as follows: cT1a-cT3a, PSA ≤ 20 ng/ml, initial minimum biopsy of 10 cores, number of affected cores ≤ 3, 1st Gleason score of 3 and 2nd Gleason score ≤ 4 and a known prostate volume (in cc). A unified follow-up was not established for all recruiting centres; however, a survey was conducted that reflects the follow-up characteristics based on a number of tangible parameters that allow for their comparison. With the same philosophy of flexibility, the use of certain biomarkers and multiparametric MRI was not considered necessary for inclusion. Results: We describe the Registry's characteristics and possibilities, as well as the preliminary results from the 324 patients included in its first 5 months of operation in the 15 recruiting centres. We also report the clinical-pathological variables, biomarkers, radiodiagnosis technique and quality-of-life questionnaires considered for the database, as well as the possibilities for indefinite follow-up, remaining open to any active treatment recognized in clinical guidelines. Conclusions: The AEU-PIEM/2014/0001 represents an extremely useful tool for all Spanish urologists for multicentre clinical research. The registry will undoubtedly enable the dissemination of active surveillance of our patients in a more coordinated manner, thus maintaining the advantages of optimised opportunistic screening for prostate cancer without resulting in overtreatment

RESUMO

Objetivos: Conocer las características de la esquistosomiasis vesical por Schistosoma haematobium en pacientes inmigrantes. Material y métodos: Se presenta el estudio retrospectivo de 41 casos diagnosticados microbiológicamente en nuestro hospital en los últimos 16 años, recogiendo datos de origen, edad, forma de presentación, pruebas diagnósticas y tratamiento. Resultados: Todos eran pacientes africanos con edades comprendidas entre 4 y 32 años y presentaban hematuria macroscópica terminal. La mayoría (85%) eran varones. Se diagnosticaron con estudio microbiológico de orina en todos los casos y en uno de biopsia por cistoscopia de una lesión típica vesical. La hematuria terminal es el signo clínico más representativo. Se trataron con praziquantel. Conclusiones: La epidemiología y la hematuria terminal intermitente en pacientes africanos debe hacer sospechar esquistosomiasis vesical como primera opción diagnóstica. El estudio microbiológico de orina es una prueba rápida, no invasiva y con alta rentabilidad diagnóstica que evitaría la realización de exploraciones invasivas. Su sencillo tratamiento asegura un alto nivel de cumplimiento y consecuente eficacia


Objectives: To know the characteristics of vesical schistosomiasis caused by schistosoma hematobium in immigrant patients. Materials and methods: The retrospective study of 41 cases microbiologically diagnosed in our hospital over the last 16 years is presented. Data were collected on origin, age, presentation form, diagnostic tests and treatment. Results: All were African patients whose ages ranged from 4 to 32 years and who had terminal macroscopic hematuria. Most of the patients (85%) were men. In all of the cases, diagnosis was by a urinary microbiological study and in one case, cystoscopy with a biopsy of a typical vesical lesion. Terminal hematuria is the most representative clinical sign. They were treated with praziquantel. Conclusions: The epidemiology and intermittent terminal hematuria in African patients should lead to the suspicion of vesical schistosomiasis as the first diagnostic option. Urinary microbiological study is a rapid, non-invasive test with high diagnostic yield that would avoid performing invasive studies. Its simple treatment assures high level of compliance and consequent efficacy
