Sedentarismo y sobrepeso como factores de riesgo en la detección del cáncer de próstata y su agresividad

ObjectiveTo analyze the influence of sedentary (SE) and overweight (OW) in the risk of prostate cancer detection (CP) and aggressiveness.Material and methodWe performed prostate biopsy (PB) to 2,408 consecutive male, 5 ARIs untreated, because of elevated serum PSA above 4.0 ng/mL (91%) or suspicious digital rectal examination (9%). In all ultrasound guided PB, 10 cores were obtained plus 2 to 8 additionals, according to age and prostate volume. Physical activity was assessed using a survey (SE vs non-SE) and calculated body mass index (normal vs OW > 25 kg/cm²). The tumor aggressiveness was evaluated according to the Gleason score (high grade «HG»: Gleason> 7) and D’Amico risk (high risk «HR»: T > 3a or PSA > 20 or Gleason score > 7).ResultsWe found a significant association between SE (52.5%) and OW (72.9%), P < .001. The overall PC detection rate was 35.2%. In men with SE it was 36.7% and non-SE 33.6%, P = .048. The overall rate of AG tumors was 28.3%, 29.2% in men with SE and 27.1 in non-SE, P = .261. The overall rate of AR tumors was 35%, 39.7% in men with SE and 29.4% non-SE, P < .001. CP was detected in 38.1% of men with normal BMI and 34.3% in men with OW, P = .065. HG tumor rates were 18.1% and 31.4% respectively, P < .001 and AR tumor rates were 22.6% and 39.2% respectively, P < .001. Binary logistic regression showed that SE was an independent predictor of CP, OR .791 (95% CI: .625-.989), P = .030. SE and OW were independent predictors of HG: OR .517 (95% CI: .356-.752), P = .001, and OR 1.635 (95% CI: 1070-2497), p = 0.023. SE and OW were also independent predictors of HR: OR .519 (95% CI .349-.771), P = .001, and OR 1.998 (95% CI 1.281-3.115), P = .002.ConclusionsIn men who met criteria for prostate biopsy an association between sedentary and overweight exist. A sedentary lifestyle is associated with increased risk of PC detection while sedentary and overweight were associated with more aggressive tumors.     

Linfoma prostático y revisión de la literatura

Prostatic Lymphoma is an exceptional pathology, that usually is diagnosed because its prostatic symthomatology or as consequence of its invasion by an extraprostatic lymphoma. We present a case of a patient affected by a prostatic lymphoma and we perform a review of the literature in order to establish the diagnostic and therapeutic steps.     

Ensayo clínico,aleatorizado, abierto y prospectivo,de 3 años de seguimiento,que compara la eficacia del TVT y la colposuspensión de Burch como tratamiento de la incontinencia urinaria de esfuerzo femenina

BackgroundEvidence comparing the effectiveness of tension-free vaginal tape (TVT) with Burch colposuspension (CS) over a long-term follow-up is scarce.PurposeTo compare TVT with CS as primary treatment for female stress urinary incontinence (SUI).DesignOpen randomised clinical trial with a three-year follow-up period.Participants49 consecutive women aged 35 to 70 with SUI demonstrated by a urodynamic study.SettingUrology department of Severo Ochoa general hospital in Leganés, Madrid, Spain.Intervention24 random patients treated with TVT and 25 with CS.MeasurementsMain variable: assessment before treatment and at six months, one year and three years after the operation using the incontinence severity symptoms index (SSI) and the incontinence impact symptoms index (SII). Secondary variable: three groups for assessing cure, improvement and failure rates.ResultsTime in surgery, consumption of postoperative analgesics and length of the postoperative hospital stay were lower in the TVT group (41.1 ± 10.9 minutes; 6 [2.8-10.5] capsules and 1 [1-2] days vs. 57.1 ± 18.3 minutes, 23.5 [18.0-31.5] capsules and 3 [3-3] days [p < 0.0001]). There was a significant reduction in SSI and SII scores in both groups and no differences in surgical complications, urgency, obstruction, one-hour pad test, urine culture, flowmetry, costs and cure rates at any moment during follow-up (cured/improved 76.2%, 78.3% and 77.3% at six months, one year and three years for TVT vs. 87.5%, 87.5% and 91.3% for CS; p = 0.32, p = 0.4 and p = 0.19).LimitationsThe trial is open, which can create observer bias. A study with a higher number of patients or a longer follow-up time could show differences between the procedures that we were unable to observe in this study, due to our budget and time limits.DiscussionBased on both short-term and long-term results, TVT is as effective as CS for the treatment of SUI, and has similar subjective cure and surgical complication rates. Time in surgery, consumption of analgesics and length of postoperative hospital stay are all lower in the TVT group. In our clinical setting, with a one-day postoperative stay for TVT, the two procedures have similar costs.     

Efecto de la varicocelectomía en la fertilidad. Indicaciones,técnicas y resultados

We define varicocele as the dilation of the veins that make up the pampiniform plexus, which is made up of three branches, the internal spermatic, deferential and external spermatic. The World Health Organization (WHO) has determined that varicocele is an important cause of male infertility. This has been acknowledged by several studies that have shown this cause-effect relationship. Varicocele does not always generate infertility. In fact, many patients with varicocele are fertile, decreasing their percentage in the progression of the pathology and the association with other factors such as tobacco, marijuana or endocrine disorders (diabetes or hypothyroidism). Infertility is a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse (WHO).Surgical therapeuticsSurgery is indicated in cases of grade 3 varicocele (when seen through the scrotal skin and palpable as a ‘bag of worms’ without Valsalva maneuver), cases of atrophy or growth arrest with volume differences of more than 2 cm³ between testes, when accompanied by pain and alterations in the spermiogram in young patients.ConclusionThe presence of varicocele determines the performance of varicocelectomy, with the inguinal approach in its three branches being the approach of preference. The laparoscopic approach will be used in specific cases.     

La resonancia magnética y el índice MaRIA en la valoración preoperatoria de la enfermedad de Crohn ileal

BackgroundAccurate quantification of the inflammatory activity in Crohn's Disease is essential to determine adequate treatment for each patient. The aim of the present study is to assess the correlation between the pre-operative Magnetic Resonance Index of Activity (MaRIA) and the histologic degree of inflammation from surgically resected intestinal Crohn's Disease lesions.MethodsThis is a prospective study including a consecutive case series of patients with small bowel Crohn's Disease, who underwent surgical resection. Magnetic resonance enterography was performed in the 3 months prior to surgery, applying a pre-established protocol. Relative contrast enhancements, wall thickness, presence of edema or ulcerations were the parameters used to calculate the MaRIA Index. All patients underwent surgery and every specimen was analyzed. The modified Chiorean classification was applied for the histological analysis and an ordinal regression analysis was used to correlate MaRIA and the grade of inflammation for each lesion.Results59 lesions from 35 different patients were analyzed. The degree of inflammation of the lesions was statistically correlated to the MaRIA values (P=.002). The MaRIA index was significantly different (P<.001) between the different histological types of the Crohn's Disease lesions (inflammatory/ fibrotic). The best cut-off for detecting severe inflammation using MaRIA was 20 (AUC: 0.741; 74.1% sensitivity and 78.1% specificity).ConclusionMaRIA is a reliable tool to distinguish inflammatory from fibrotic lesions. Therefore, it could be considered essential for determining the most appropriate Crohn's Disease treatment for each patient.     

Sensibilidad,especificidad y fiabilidad de la escala RIPASA en el diagnóstico de apendicitis aguda en relación con la escala de Alvarado

Introduction

In order to avoid delay in the diagnosis of acute appendicitis and reduce the margin of error, the use of scales has been used. The aim of this study was to compare the effectiveness of the Alvarado and RIPASA scores in the clinical diagnosis of acute appendicitis and to correlate with the histopathological results.

Análisis de efectividad y costes sanitarios de la inmunoprofilaxis con autovacuna MV140, vacuna MV140 y tratamiento antibiótico continuado en la prevención de las infecciones urinarias recurrentes

IntroductionThe objective of this study was to compare the results on prevention of uncomplicated recurrent UTI between continuous use of antibiotics, MV140 autovaccine and MV140 polybacterial vaccine from collection strain.Methods377 patients were prospectively analyzed from January 2017 to August 2019 and divided into 3 groups according to the prophylaxis. Group A (126): antibiotics, Group B (126): MV140 autovaccine, Group C (125): MV140 polybacterial vaccine from the collection strain. Variables analyzed were: gender, age, menopause, number of UTI at baseline and 3 and 6 months after the end of prophylaxis, health cost along follow-up at 3 and 6 months.ResultsAt 3 months, group A had 0-1 UTI in 65%, group B had 0-1 UTI in 80.8% and group C in 81.7%. At 6 months, group A had 0-1 UTI in 44.4%, group B had 0-1 UTI in 61.6% and group C in 74.6%. Regarding health cost along follow-up, at 3 months group A had €21,171.87, group B had €20,763.73 and group C €18,866.14. At 6 months, health cost was €32,980.35 in group A, €28,133.42 in group B, and €23,629.19 in group C.ConclusionsMV140 autovaccine and MV140 polybacterial vaccine were more efficient with lower number of UTI at 3 and 6 months and lower health cost along follow-up compared to continued prophylaxis with antibiotics (p < .05). Polybacterial MV140 vaccine from collection strain had higher effect to reduce the number of UTI and less health cost than autovaccine.     

Confiabilidad interevaluador de la medición de la excursión diafragmática y fracción de engrosamiento diafragmático mediante ultrasonografía en voluntarios sanos

Background and objectiveTo determine the inter-rater reliability in the ultrasonographic (US) measurement of the diaphragmatic excursion (DE) and the diaphragm thickness fraction (DTF) performed by non-medical health professionals in healthy people.Participants and methodsProspective observational study in a third level hospital in Cali, Colombia. Measurements were made to 30 healthy volunteers chosen by convenience sampling, without a history of lung diseases, with ages between 18-60 years. A pilot test was previously carried out with 8 healthy volunteers. US measurements of DE, and DTF were based on previously published protocols. Each assessor independently observed several cycles of normal quiet breathing for 3 minutes to establish a baseline. The Intraclass Correlation Index (ICC) was used to evaluate the inter-rater reliability in the measurements of DE and DTF, with 95% confidence intervals and a P < .05.ResultsSubstantial agreement was identified in the measurement of DE in the splenic and hepatic windows because the ICC was greater than 0.6 (P < .05). The measurement of the DTF in the hepatic window showed slight agreement in both 2D and M modes (P > .05). In the splenic window, the measurement of the DTF in the 2D mode was found to be moderate agreement and for the M mode a slight agreement was found (P > .05)ConclusionsThe diaphragmatic US constitutes a reproducible method with acceptable inter-rater reliability for the measurement of inspiratory/expiratory thickness, and with little reliability for the measurement of DTF.     

Papel de PCA3 y SelectMDx en la optimización de la vigilancia activa en el cáncer de próstata

Introduction and objectivesA not negligible percentage of patients included in active surveillance (AS) for low and very low risk prostate cancer (PCa) are reclassified in the confirmatory biopsy or have disease progression during follow-up. Our aim is to evaluate the role of PCA3 and SelectMDx, in an individual and combined way, in the prediction of pathological progression (PP) in a standard AS program.Materials and methodsProspective and observational study comprised of 86 patients enrolled in an AS program from 2009 to 2019, with results for PCA3 and SelectMDx previous to PCa diagnosis or during their confirmatory period. Univariate and multivariate analysis were performed to correlate PCA3 and SelectMDx scores as well as clinical and pathological variables with PP-free survival (PPFS). The most reliable cut-offs for both biomarkers in the context of AS were defined.ResultsSelectMDx showed statistically significant differences related to PPFS (HR: 1.035; 95% CI: 1.012-1.057) (P = .002) with a C-index of 0.670 (95% CI: 0.529-0.810) and AUC of 0.714 (95% CI: 0.603-0.825) at 5 years. In our series, the most reliable cut-off point for SelectMDx was 5, with a sensitivity and specificity for PP of 69.8% and 67.4%, respectively. Same figure for PCA3 was 65, with a sensitivity and specificity for PP of 51.16% and 74.42%, respectively. The combination of both biomarkers did not improve the prediction of PP, C-index 0.630 (95% CI: 0.455-0.805).ConclusionsIn the context of low or very low risk PCa, SelectMDx > 5 predicted 5 years PP free survival with a moderate discrimination ability outperforming PCA3. The combination of both tests did not improved outcomes.     

Actualización y optimización de la vigilancia activa en cáncer de próstata en 2021

Introduction and objectivesWithin the paradigm shift of the last decade in the management of prostate cancer (PCa), perhaps the most relevant event has been the emergence of active surveillance (AS) as a mandatory strategy in low-risk disease. We carry out a critical review of the clinical, pathological and radiological improvements that allow optimizing AS in 2021.Material and methodsCritical narrative review of the literature on improvement issues and controversial aspects of AS.ResultsAdequate use of traditional criteria, optimized by enhanced biopsy and calculation of the prostate volume technique thanks to multiparametric magnetic resonance imaging (mpMRI) allow a better selection of patients for AS. This management should not be limited to patients under 60 years of age, and patients with intermediate-risk PCa should be carefully selected to be included. Biopsies are still required in the follow-up, which can be personalized according to risk patterns. The pathologist must identify the cribriform or intraductal histology on biopsies in order to exclude these patients from AS, in the same way as with patients with alterations in DNA repair genes.ConclusionsControversial indications such as the inclusion of patients from intermediate-risk groups, or the transition to active treatment due to exclusive progression in tumor volume, should be further optimized. It is possible that the future competition of tissue biomarkers, the refinement of objective parameters of mpMRI and the validation of PSA kinetics calculators may sub-stratify risk groups.     

Impacto de la resección no planificada y la reintervención de sarcomas de partes blandas en su pronóstico

IntroductionUp to 40% of all initial operations for soft tissue sarcoma (STS) are unplanned, which would leave residual macroscopic tumor in more than 50% of the cases. The effect this has on local recurrence rate, metastases rate and survival has never been fully established, due to the lack of randomized studies.MethodsRetrospective review of patients with STS treated in our unit between January 2001-January 2016. We classified them whether they had been treated by initial planned or unplanned operation. Outcomes were compared in both groups globally and stage-matched. Endpoints were local recurrence and distant metastases.ResultsTwenty-three patients of STS underwent a planned excision and 16 an unplanned excision, 13 of them underwent further re-excision. 40% of patients with planned excision had an advanced stage in regard to the unplanned excision group which presented earlier stages. 77% of patients with unplanned excision had residual tumor identified after surgical re-excision. Local recurrence rate in the unplanned excision group was considerably higher 73,5% vs. 43,8%. Metastases rate was lower in planned excision group, 45,5% vs 56,3% (P > .05). The recurrence pattern in the unplanned excision group was unstable, with worse outcomes in earlier stages.ConclusionThe unplanned excision of a soft tissue sarcoma may compromise disease local control, with higher rates of local recurrence and metastases, and worse functional out- comes, despite further oncological treatment. We need to recognize the clinical features for malignancy risk in soft tissue lumps for a safe diagnosis to avoid inadequate resections.     

Recomendaciones en el tratamiento antibiótico empírico de la infección intraabdominal

A significant number of patients with abdominal infection develop advanced stages of infection and mortality is still above 20%. Failure is multifactorial and is associated with an increase of bacterial resitance, inappropriate empirical treatment, a higher comorbidity of patients and poor source control of infection. These guidelines discuss each of these problems and propose measures to avoid the failure based on the best current scientific evidence.     

La incidencia acumulada y los factores predictivos de la cistitis rádica en pacientes con cáncer de próstata localizado

Evidencia en seguimiento y pronóstico del cáncer de unión esofagogástrica

Five-year survival of tumors of the esophagogastric junction is 50%, in the most favourable stages and with the most effective adjuvant treatments. More than 40% of patients will have recurrences within a short period, usually the first year after potentially curative surgery. Survival after this recurrence is usually less than 6 months because treatment is not very effective, be it palliative chemotherapy, radiotherapy or surgical excision of single recurrences. As the detection of asymptomatic recurrences allows for earlier and more effective treatments to be used, the type and frequency of follow-up has an influence on survival.
