Introduction For low-risk prostate cancer (PCa), curative treatment with radical prostatectomy (RP) can be performed, reporting a biochemical relapse-free survival rate (bRFS) at 5 and 7 years of 90.1% and 88.3%, respectively. Prostatic specific antigen (PSA), pathological stage (pT), and positive margins (R1) are significant predictors of biochemical relapse (BR). Even though pelvic lymphadenectomy is not recommended during RP, in the literature, it is performed in 34% of these patients, finding 0.37% of positive lymph nodes (N1). In this study, we aim to evaluate the 10-year bRFS in patients with low-risk PCa who underwent RP and extended pelvic lymph node dissection (ePLND). Methodology All low-risk patients who underwent RP plus bilateral ePLND at the National Cancer Institute of Colombia between 2006 and 2019 were reviewed. Biochemical relapse was defined as 2 consecutive increasing levels of PSA > 0.2 ng/mL. A descriptive analysis was performed using the STATA 15 software (Stata Corp., College Station, TX, USA), and the Kaplan-Meier curves and uni and multivariate Cox proportional hazard models were used for the survival outcome analysis. The related regression coefficients were used for the hazard ratio (HR), and, for all comparisons, a two-sided p-value ˂ 0.05 was used to define statistical significance. Results Two hundred and two patients met the study criteria. The 10-year bRFS for the general population was 82.5%, statistically related to stage pT3 (p = 0.047), higher Gleason grade group (GG) (p ≤ 0.001), and R1 (p ≤ 0.001), but not with N1. A total of 3.9% of the patients had N1; of these, 75% had R1, 25% GG2, and 37% GG3. Among the N0 (non-lymph node metástasis in prostate cáncer) patients, 31% of the patients had R1, 41% GG2, and 13% GG3. Conclusions Our bRFS was 82.5% in low-risk patients who underwent RP and ePLND. With higher pT, GG, and presence of R1, the probability of BR increased. Those with pN1 (pathologicaly confirmed positive lymph nodes) were not associated with bRFS, with a pN1 detection rate of 3.9%. Details: In low-risk PCa, curative treatment with RP can be performed, reporting a bRFS rate at 5 and 7 years of 90.1% and 88.3%, respectively. Despite the fact that pelvic lymphadenectomy is not recommended during RP in clinical guidelines, in the literature, it is performed in 34% of these patients, finding 0.37% of N1. In this study, we report the 10-year bRFS in patients with low-risk PCa who underwent surgery.

Objective To describe the five-year overall survival (OS) and perioperative morbidity of patients with renal cell carcinoma (RCC) with venous tumor thrombus (VTT) treated through radical nephrectomy and thrombectomy. Materials and Methods We evaluated a cohort of 530 patients with a diagnosis of RCC from January 2009 to December 2019, and found VTT in 42 of them; these 42 patients composed the study sample. The patients were stratified according to the Neves Thrombus Classification (NTC). The baseline and perioperative characteristics, as well as the follow-up, were described. The Kaplan-Meier curve and its respective Cox regression were applied to present the 5-year OS and the OS stratified by the NTC. Results The average age of the sample was of 63.19 ± 10.7 years, and there were no differences regarding gender. In total, VTT was present in 7.9% of the patients. According to the NTC, 30.9% of the cases corresponded to level I, 21.4%, to level II, 26.1%, to level III, and 21.4%, to level IV. The 5-year OS was of 88%. For level-I and level-II patients, the 5-year OS was of 100%, and of only 38% among level-IV patients. Complications, mostly minor, occurred in 57% of the cases. Conclusions Radical nephrectomy with thrombectomy is a morbid procedure; however, most complications are minor, and the five-year mortality is null for patients in NTC levels I and II, and low for levels III and IV, and it may be even lower in level-III patients when standardizing transesophageal echocardiogram intraoperatively and routinary extracorporeal bypass. Thus, we recommend considering this surgery as the first-line management in patients with RCC and VTT.

Objetivo Exponer los factores que han sido asociados al desarrollo de disfunción eréctil (DE) en las personas con virus de la inmunodeficiencia humana (VIH) y cuál es la prevalencia de la disfunción eréctil en esta población. Métodos Se realizó una revisión de alcance utilizando las siguientes bases de datos: MEDLINE, CENTRAL, Embase, Scopus, Lilacs, y Psycinfo. Los artículos incluidos debían tener cualquier información relacionada con la DE en personas con VIH, su prevalencia, y posibles factores asociados. Se filtraron un total de 2.726 artículos por título y resumen, y, de estos, se seleccionaron 22 referencias para revisión de texto completo y análisis. Resultados Se encontró que las personas con VIH tienen una mayor probabilidad de presentar DE en comparación con las personas sin VIH. Algunos estudios han establecido una asociación entre la DE y trastornos psicológicos o factores orgánicos, como la lipodistrofia, la hipertensión arterial, la hipercolesterolemia, la diabetes mellitus, la depresión, la ansiedad, y el hipogonadismo. La ingesta de terapia antirretroviral (TARV), más específicamente los inhibidores de la proteasa, sigue siendo cuestionada como causante de DE en pacientes con VIH. Conclusiones Ante un paciente con diagnóstico de VIH, se debe ahondar sobre DE con el fin de recomendar e iniciar conductas terapéuticas que aseguren un mejoramiento en su calidad de vida.

Purpose To identify metabolites in humans that can be associated with the presence of malignant disturbances of the prostate. Methods In the present study, we selected male patients aged between 46 and 82 years who were considered at risk of prostate cancer due to elevated levels of prostate-specific antigen (PSA) or abnormal results on the digital rectal examination. All selected patients came from two university hospitals (Hospital Universitario del Valle and Clínica Rafael Uribe Uribe) and were divided into 2 groups: cancer (12 patients) and non-cancer (20 patients). Cancer was confirmed by histology, and none of the patients underwent any previous treatment. Standard protocols were applied to all the collected blood samples. The resulting plasma samples were kept at -80°C, and a profile of each one was acquired by nuclear magnetic resonance (NMR) using established experiments. Multivariate analyses were applied to this dataset, first to establish the quality of the data and identify outliers, and then, to model the data. Results We included 12 patients with cancer and 20 without it. Two patients were excluded due to contamination with ethanol. The remaining ones were used to build an Orthogonal Projections to Latent Structures Discriminant Analysis (OPLS-DA) model (including 15 non-cancer and 10 cancer patients), with acceptable discrimination (Q2 = 0.33). This model highlighted the role of lactate and lipids, with a positive association of these two metabolites and prostate cancer. Conclusions The primary discriminative metabolites between patients with and without prostate cancer were lactate and lipids. These might be the most reliable biomarkers to trace the development of cancer in the prostate.
意图 鉴定人类体内可能与前列腺恶性病变相关的代谢产物。方法 在本研究中,我们选择了年龄在46岁至82岁之间的男性患者,他们因前列腺特异性抗原(PSA)水平升高或直肠指检结果异常而被认为有患前列腺癌症的风险。所有入选的患者均来自两所大学医院(瓦莱大学医院和Clínica Rafael Uribe Uribe),并分为两组:癌症(12名患者)和非癌症(20名患者)。癌症经组织学证实,无一例患者接受过任何治疗。标准方案适用于所有采集的血液样本。所得血浆样品保持在-80°C,并使用既定实验通过核磁共振(NMR)获得每种血浆样品的图谱。将多变量分析应用于该数据集,首先确定数据的质量并识别异常值,然后对数据进行建模。后果 我们纳入了12名癌症患者和20名非癌症患者。两名患者因乙醇污染而被排除在外。剩下的用于建立潜在结构判别分析(OPLS-DA)的正交投影模型(包括15名非癌症患者和10名癌症患者),具有可接受的判别(Q2 = 0.33)。该模型强调了乳酸盐和脂质的作用,这两种代谢产物与前列腺癌症呈正相关。结论 癌症患者和非前列腺患者之间的主要鉴别代谢产物是乳酸盐和脂质。这些可能是追踪前列腺癌症发展最可靠的生物标志物。

Introducción y Objetivo El reflejo bulbocavernoso (RBCV) se ha observado ausente incluso en pacientes neurológicamente sanos. Los trastornos funcionales del piso pélvico deben incluir su evaluación.Nuestro objetivo primario fue evaluar la prevalencia de ausencia de RBCV en pacientes sanos. El objetivo secundario fue observar la afectación del RBCV en presencia de otras comorbilidades cómo enfermedad neurológica y diabetes mellitus tipo 2. Métodos Estudio descriptivo y retrospectivo, en el que se revisaron mil expedientes clínicos de pacientes sometidos a estudio urodinámico a quienes se les realizó exploración mecánica del RBCV como parte de una exploración rutinaria. Se realizó estadística descriptiva para las variables cuantitativas y cualitativas utilizando la prueba tde Student y la de chi cuadrado, respectivamente. Se consideraron estadísticamente significativos valores de p < 0,05. Resultados La muestra tenía una media de edad de 59,84 años (desviación estándar [DE]: ± 14,13 años), y contenía 36,19% de mujeres y 21,13% de hombres sin enfermedad neurológica y RBCV ausente. Se observó mayor ausencia de RBCV en pacientes con presencia de enfermedad neurológica en comparación con pacientes neurológicamente sanos: 21,6% versus 10,6%, respectivamente (p < 0,0001); además, se observó una ausencia importante de RBCV en presencia de diabetes mellitus en comparación con pacientes no diabéticos: 30.8% versus 18.8%, respectivamente (p < 0,0001). No se observaron diferencias al comparar grupos con respecto a disfunción vesical. Conclusión La ausencia de RBCV no es exclusiva de una enfermedad neurológica con repercusión de síntomas del tracto urinario inferior, y la proporción de pacientes neurológicamente sanos con ausencia de RBCV no es despreciable. No se encontró una diferencia significativa en los grupos con ausencia de RBCV con respecto a disfunción vesical.

Objectives Ionizing radiation imaging is commonly used for diagnosis and follow up in children with vesicoureteral reflux (VUR). We aim to measure the effective dose (mSv) in patients with VUR. Methods We reviewed our electronic database of patients under 8-years-old with VUR. Primary endpoint was to calculate the effective radiation dose (ED). Absolute frequencies and percentages were reported for global qualitative variables. This study conducted a logistic regression model to calculate the odds ratio for radiation exposure. Analysis was performed using STATA version 14.0 (StataCorp LLC, College Station, TX, EEUU). Results A total of 140 patients were found, 97 were assessed for eligibility. We included 59 patients in the final analysis. Mean age was 20 ± 17.9 months, 66% were females. Most cases of VUR were bilateral (44%) and high grade (93.4%). The lowest number of studies per patient was two, with a minimum radiation of 5.7 mSv. The highest radiation was estimated at 20.7 mSv corresponding to a total of five studies. Logistic regression showed that highest grades of VUR and age of first UTI episode were associated with higher ED (OR, 1.7; 95% CI, 0.87-3.31), (OR 1.02; 95% CI 0.97-1.07) respectively. A mean ED for children with VUR was estimated of 5.5 ± 3 mSv/year. Conclusion In our study, the children with VUR were exposed to 5.5 mSv/year without counting the natural background radiation, which is alarming, and we believe should raise awareness worldwide in how we are unnecessarily diagnosing indolent VUR cases and following patients.

Objective Research on gender dysphoria (GD) has been growing over the last decades with increasing interest in understanding and characterizing the causal relationships between psychological, genetics, hormonal, and sociocultural factors. Changes and acceptance of this condition as non-pathologic have led to significant changes in general perspective and its management over time. Our objective is to carry out a bibliometric analysis to know the publication trends and quality of evidence related to gender dysphoria. Methods A systematic search and critical review of the literature was carried out between January 1900 and December 2018 to perform a bibliometric analysis. Research was done in the following databases: OVID, PubMed, EMBASE, Scopus, Web of Science and Google Scholar. The medical subject headings (MeSh) terms used were: gender dysphoria; and surgery and psychology. The results were plotted using the VOSviewer version 1.6.8. Statistical analyses were performed with the IBM SPSS, Version 25.0. Results A total of 1,239 manuscripts were identified, out of which 1,041 were selected. The average number of cited times per year per manuscript is 1.84 (interquartile range [IQR] 0-2.33). The average impact index was 47.8 (IQR 20-111.6). The median of total citations per manuscript was 3 (IQR 0-33.1), and the highest number of citations per manuscript was 484. Most publications focus on the psychological aspects of GD, and there is a significant amount of manuscripts related to social and anthropological issues. Most articles have a low level of scientific evidence. Conclusion There is a great amount of published literature on GD; however, there is a significant level of disagreement in many respects on this topic. Regarding surgical gender-affirmation, there is a lack of information supported by high level of evidence to uphold the emerging expansion of medical practices.

Objective Among regional blocks, the quadratus lumborum fascial plane block (QLB) has been well described, but the description of its use and efficacy for pediatric patients undergoing upper abdominal urologic surgery is limited. We present a case series examining the use of the QLB for postoperative pain management in children undergoing upper tract surgery. Methods From August 2019 to August 2020, through a chart review, we identified 5 patients who had undergone a QLB for upper urinary tract surgery via a flank incision. Posterior QLB was performed after induction of general anesthesia. A single injection of 0.5mL/kg of either 0.25% or 0.5% ropivacaine with 1mcg/kg of clonidine was administered. Patients received fentanyl IV (1 mcg/kg), and acetaminophen IV (15mg/kg) as adjuvants during the operation. Postoperative pain was managed with oral acetaminophen and ibuprofen. Results The average postoperative pain score during the entire admission was 1, with the lowest being 0 and highest, 3. No administration of rescue narcotics was required in the postanesthesia care unit or on the floor. The average length of stay ranged from 0 to 1 day. No complications associated with the regional QLB were identified. Conclusions Our series suggests the QLB may be considered as a regional anesthetic option to minimize narcotic requirements for children undergoing upper abdominal urological surgery via flank incision. Additional studies are needed to compare the efficacy of the QLB versus alternate regional anesthetic blocks for upper tract urological surgery via flank incision in children and to determine effective dosing and use of adjuvants.

Resumen Introducción y Objetivo Con el advenimiento de nuevas tecnologías, vienen controversias respecto al espectro de sus aplicaciones. El costo derivado de estas tecnologías juega un papel muy importante en el momento de la toma de decisiones terapéuticas. Es por esto que consideramos relevante estimar la costo-efectividad de la nefrolitotomía percutánea comparada con la nefrolitotomía retrógrada flexible con láser de holmio en pacientes con litiasis renal de 20 mm a 30 mm en Colombia. Materiales y Métodos Por medio de la construcción de un modelo de árbol de decisión usando el programa Treeage (TreeAge Software, LLC, Williamstown, MA, EE.UU.), se realizó una comparación entre la nefrolitotomía percutánea y la nefrolitotomía retrógrada flexible con láser de holmio en pacientes con litiasis renal de 20 mm a 30 mm. La perspectiva fue la del tercer pagador, y se incluyeron los costos directos. Las cifras fueron expresadas en pesos colombianos de 2018. La mejoría clínica, definida como el paciente libre de cálculos, fue la unidad de resultado. Se hizo una extracción de datos de efectividad y seguridad por medio de una revisión sistemática de la literatura. La razón de costo-efectividad incremental fue calculada. Resultados El modelo final indica que la nefrolitotomía percutánea puede ser considerada como la alternativa más costo-efectiva. Los hallazgos fueron sensibles a la probabilidad de mejoría clínica de la nefrolitotomía percutánea. Conclusión Teniendo en cuenta las variables económicas, los supuestos del modelo y desde la perspectiva del tercer pagador, la nefrolitotomía percutánea para el tratamiento de pacientes con cálculos renales de 20 mm a 30 mm es costo-efectiva en nuestro país. Estos hallazgos fueron sensibles a los costos y a la efectividad de los procedimientos quirúrgicos.
