Postnatal cytomegalovirus infection and pulmonary vascular disease in extremely premature infants: A case series.

BACKGROUND: Pulmonary vascular disease (PVD) is a major determinant of both morbidity and mortality in extremely low birth weight infants. It is biologically plausible that postnatal cytomegalovirus (pCMV) infection may lead to PVD in premature infants secondary to pneumonitis or via derangement of pulmonary vascular development directly through endothelial dysfunction. Uncertainty remains, however, regarding thresholds for intervention in premature infants with cardiorespiratory instability and presumed CMV infection likely secondary to the limited understanding of the natural history of the disease. METHODS/RESULTS: We describe four cases of premature infants with clinical and echocardiography features of PVD, in the setting of postnatally acquired CMV. All patients had atypical PVD trajectories, refractory to vasodilator treatment, which improved after initiation of CMV treatment. CONCLUSION: We highlight the need to consider postnatally acquired CMV infection in patients with PVD non-responsive to standard pulmonary vasodilator therapies or disease severity which is out of proportion of the usual clinical trajectory. Treatment of extremely premature infants with CMV-associated PVD may have positive impact on cardiorespiratory health, although duration of therapy remains uncertain.

Reconstruction Techniques After Partial Nephrectomy: Classic vs. Sutureless Approach-A Narrative Review.

PURPOSE OF REVIEW: The purpose of this review is to update the information about the different types of reconstruction after partial nephrectomy, with special emphasis on the new methods of suture-free hemostasis currently available. RECENT FINDINGS: The aim of renal reconstruction is to avoid bleeding and leakage of the collecting system, but now the renorrhaphy technique used is considered one of the modifiable determinants of renal function after surgery. In an attempt to avoid the loss of renal function implicit in classic reconstruction, new techniques have been described to control hemostasis and urinary leakage, which employ fewer suture layers, different suture materials and designs, and a wide range of commercially available hemostatic materials. Multiple suture characteristics have been studied as a potential factor influencing the renal function observed after partial nephrectomy. Single-plane suture techniques, the use of bearded sutures, and running sutures seem to be associated with less deterioration in postoperative renal function, and deep medullary sutures should be avoided to avoid affecting the arcuate arteries. Sutureless hemostasis systems could prevent the deterioration of renal function and complications derived from suturing, also reducing ischemia time and surgical time without increasing the risk of complications.

Development of an immune-nutritional prognostic index in patients with muscle-infiltrating bladder cancer candidates for radical cystectomy.

INTRODUCTION: Muscle-infiltrating bladder tumor (MIBT) has a recurrence-free survival (RFS) of 50% at 5 years. Although neoadjuvant chemotherapy (NCT) has increased it by 8%, which group of patients benefits the most from this treatment remains unclear. OBJECTIVE: Evaluate the prognostic value of immune-nutritional status in patients with MIBT who are candidates for cystectomy, and to develop a score that allows identifying patients with a worse prognosis (pT3-4 and/or pN0-1). MATERIAL AND METHODS: A retrospective analysis was carried out on 284 patients with MIBT treated with radical cystectomy. Preoperative laboratory tests were analyzed and immune-nutritional indices were calculated. The Kaplan-Meier method was used to calculate the PFS. Cox regression was used for multivariate analysis. RESULTS: Univariate analysis showed a statistically significant relationship with leukocyte/lymphocyte index (p = 0.0001), neutrophil/lymphocyte index (p = 0.02), prognostic nutritional index (p = 0.002), and platelet/lymphocyte ratio (p = 0.002). In multivariate analysis, the leukocyte/lymphocyte ratio (p = 0.002) and PNI (p = 0.04) behaved as independent prognostic factors of decreased RFS. Based on these, a prognostic score was developed to classify patients into 3 prognostic groups. Eighty percent of patients with pT3-4 and/or pN0-1 tumors were in the intermediate-poor prognostic groups. CONCLUSION: The implementation of a precystectomy immune-nutritional score in clinical practice would help in the selection of a group of patients with a more unfavorable pathologic stage and worse PFS. We believe that these patients could benefit more from a NACT.

Elaboración de un índice pronóstico inmunonutricional en pacientes con cáncer de vejiga músculo-infiltrante candidatos a cistectomía radical / Development of an immune-nutritional prognostic index in patients with muscle-infiltrating bladder cancer candidates for radical cystectomy

Introducción El tumor vesical músculo-infiltrante (TVMI) tiene una supervivencia libre de recidiva (SLR) del 50% a los cinco años, la quimioterapia neoadyuvante (QTN) ha aumentado la misma un 8%, pero no está claro qué pacientes se pueden beneficiar en mayor grado de la misma. Objetivo Evaluar el valor pronóstico del estado inmunológico-nutricional en los pacientes con TVMI candidatos a cistectomía, y desarrollar un score que permita identificar precistectomía a los pacientes con peor pronóstico (pT3-4 y/o pN0-1). Material y método Se realizó un análisis retrospectivo de 284 pacientes con TVMI tratados con cistectomía radical. Se revisó la analítica preoperatoria y se calcularon índices inmunonutricionales. El método de Kaplan-Meier se utilizó para el cálculo de la SLR. Para el análisis multivariante se utilizó la regresión de Cox. Resultados Mediante análisis univariante se observó una relación estadísticamente significativa con el índice leucocito/linfocito (p = 0,0001), el índice neutrófilo/linfocito (p = 0,02) el índice pronóstico nutricional (p = 0,002), y el ratio plaqueta/linfocito (p = 0,002). En análisis multivariante, el ratio leucocito/linfocito (p = 0,002) y el IPN (p = 0,04) se comportaron como factores pronósticos independientes de disminución de SLR, y se elaboró con ello un score pronóstico que divide a los pacientes en tres grupos pronósticos. El 80% de los pacientes con tumores pT3-4 y/o pN0-1 se encontraban en los grupos de pronóstico medio-malo. Conclusión La incorporación en la práctica clínica de un score inmunonutricional precistectomía ayudaría a seleccionar a un grupo de pacientes con estadio patológico más desfavorable y peor SLR. Creemos que estos pacientes podrían beneficiarse en mayor medida de una QTN (AU)

Objetivo: Evaluación de la periodicidad de reinyección de ácido hialurónico (AH) en pacientes con gonartrosis. Objetivo secundario: relacionar el grado de artrosis con el tiempo entre infiltraciones y posible estudio por subgrupos entre los diferentes preparados comerciales. Diseño: Estudio observacional retrospectivo. Materiales y método: Revisión de historias clínicas y radiografías de los pacientes con gonartrosis tratados con AH intraarticular en el Servicio de Rehabilitación en el periodo entre enero de 2017 y junio de 2019. Variables: sociodemográficas, lateralidad, fecha del acto, grado de artrosis según Kellgren y Lawrence, AH utilizado, tiempo entre infiltraciones. Análisis estadístico mediante curvas de Kaplan-Meier considerando la reinfiltración como evento final y test de Kruskal Wallis para valores cuantitativos no paramétricos. Resultados: Analizamos 110 actos de infiltración en 67 pacientes: media de edad en momento de infiltración 72,12 años, 85,1% mujeres, 59,1% rodilla derecha. Cuatro tipos de AH: 33 casos al 1%; PM: 0,9 MDa (AH1); 12 al 1,5%; PM: 1,5 – 2 MDa (AH2), 42 al 2%; PM: 1,2 MDa (AH3) y 6 Hilano G-F20; PM: 6 MDa (AH4). En 17 ocasiones no se registró el ácido hialurónico utilizado (AH5). Se reinfiltró en 32 ocasiones (29,09%). Media de meses (Intervalo de Confianza [IC] 95%) entre infiltraciones: AH1 6,9 (5,7-8,16), AH2 12,5 (0- 35), AH3 9,3 (5,5- 13,1), AH4 5 (3 – 6,9). En dos casos en que no se pudo establecer el tipo de preparado infiltrado, el valor medio entre reinfiltraciones fue 8,5 (5,6- 11,4).No hubo resultados estadísticamente significativos al realizar un análisis comparativo el tipo de AH ni el grado de artrosis con el tiempo de reinfiltración. Conclusiones: En nuestro estudio se observa que el AH3 presentó un mayor tiempo entre infiltraciones con respecto a los otros tipos sin poder establecer diferencias significativas.(AU)

Objective: To evaluate the periodicity of hyaluronic acid (HA) reinjection in patients with knee osteoarthritis. Secondary aim: To relate the degree of arthrosis with the time between infiltrations and the possible study by subgroups between the different commercial preparations. Design: Retrospective observational study. Materials and method: Review of medical records and X-rays of patients with knee osteoarthritis that had been treated with intra-articular HA at the Rehabilitation Service in the period between January 2017 and June 2019. Variables: Socio-demographic, Laterality, Intervention Date, Degree of Arthrosis according to Kellgren and Lawrence, HA used, Time between filtrations. Statistical analysis carried out by Kaplan–Meier curves, taking into account the reinfiltration as final event, and Kruskal–Wallis test for non-parametric quantitative data. Results: We analysed 110 infiltration acts in 67 patients: average age at the time of infiltration 72.12 years, 85.1% women, 59.1% right knee. 4 types of HA: 33 cases at 1%. MW: 0.9MDa (HA1), 12 at 1.5%. MW: 1.5–2MDa (HA2), 42 at 2%. MW: 1.2MDa (HA3) and 6 Hylan G-F20. MW: 6MDa (HA4).We reinfiltrated in 31 occasions (28.2%).

Deceased donor kidney procurement: Systematic review of the surgical technique.

INTRODUCTION: Kidney procurement procedure must be carried out following a standardized technique in order to optimize kidney grafts for their subsequent implantation. OBJECTIVES: Review of the available literature on kidney procurement procedure. MATERIAL AND METHODS: Narrative review of the available evidence on deceased donor kidney procurement technique after a search of relevant manuscripts indexed in PubMed, EMBASE and Scielo written in English and Spanish. RESULTS: Deceased donor kidney procurement can be divided into two groups, donation after brain death (DBD) and donation after circulatory death (DCD). Kidney procurement in DBD frequently includes other chest and/or abdominal organs, requiring multidisciplinary surgical coordination. During the harvesting procedure, the renal vascular pedicle must remain intact for subsequent implantation and reduced ischemia time. CONCLUSIONS: Adequate execution and perfect knowledge of the technique for surgical removal and anatomy reduces the rate of graft losses associated to inadequate harvesting techniques.

Características clínicas y epidemiológicas asociadas con internación en niños con COVID-19 en un hospital pediátrico de alta complejidad: Estudio de cohorte enero-marzo 2022 / Clinical and epidemiologic characteristics associated with hospital admission in children with COVID19 in a tertiary-care pediatric hospital: A January-March 2022 cohort study

Introducción: La proporción de casos reportados de niños y adolescentes con COVID-19 aumenta progresivamente. La hospitalización relacionada con COVID-19 en niños es infrecuente, pero causa morbilidad y sobrecarga al sistema de salud. Objetivos: Describir las características clínicas y evolutivas de los niños con diagnóstico de COVID-19 en un hospital pediátrico de alta complejidad. Comparar los pacientes que requirieron internación y los que no. Material y métodos: Cohorte prospectiva. Se incluyeron todos los pacientes con diagnóstico virológico de COVID-19 desde 1.1.2022 a 1.3.22 en un hospital pediátrico de alta complejidad. Se compararon los antecedentes, características clínicas y evolutivas de los pacientes según requirieran o no internación. Se utilizó STATA 16. Resultados: n: 1764 pacientes, de ellos 958 eran varones (54%). La mediana de edad fue 56 meses (RIC 17-116). Tenían enfermedad de base 789 pacientes (46%). Las más frecuentes fueron: enfermedad oncohematológica 215 (12%), neurológica 103 pacientes (6%) , enfermedad pulmonar crónica 68 (4%), cardiopatías congénitas 65 (4%) y síndrome genético 57 pacientes (3%). Eran inmunosuprimidos: 292 (17%). Presentaron síntomas relacionados con COVID-19 1319 pacientes (79%). Requirieron internación 591 (34%). Tuvieron coinfección con otros virus respiratorios 33 pacientes (2%). Ingresaron a Cuidados intensivos en relación a la COVID-19 22 pacientes (1.3%) y fallecieron en relación con la infección 8 (0.5%). En el análisis univariado, la presencia de comorbilidades, la coinfección viral y la inmunosupresión se asociaron estadísticamente con el requerimiento de internación. El antecedente de 2 o más dosis de vacuna para SARS-CoV-2 fue un factor protector para la internación en los mayores de 3 años. En el modelo multivariado, los pacientes menores de 3 años (OR 6.5, IC95% 1.2-36.8, p 0.03), con comorbilidades (OR 2.04, IC 95% 1.7- 3.3, p 0.00) y los huéspedes inmunocomprometidos (OR 2.89, IC95% 2.1-4.1, p 0.00) tuvieron más riesgo de internación. Ajustado por el resto de las variables, haber recibido dos o más dosis de vacuna fue un factor protector para la internación (OR 0.65, IC 95% 0.49-0.87, p<0.01). Conclusiones: En este estudio de cohorte prospectivo de niños con diagnóstico confirmado de COVID-19 predominó la enfermedad sintomática. Fueron admitidos en relación con el COVID-19, 34% de los pacientes. La vacunación con dos o más dosis fue un factor protector para la internación en el modelo multivariado. Además, se asociaron estadísticamente con la hospitalización, la edad menor de 3 años, las comorbilidades previas y la inmunosupresión (AU)

Introduction: The rate of reported cases of children and adolescents with COVID-19 is progressively increasing. COVID-19-related hospital admission in children is uncommon, but leads to morbidity and places a burden on the healthcare system. Objectives: To describe the clinical characteristics and outcome of children diagnosed with COVID-19 in a pediatric tertiary-care hospital and to compare patients who required hospital admission with those who did not. Material and methods: A prospective cohort study. All patients with a virological diagnosis of COVID-19 seen between 1.1.2022 and 1.3.22 in a tertiary-care pediatric hospital were included. We compared patient history, clinical characteristics, and outcome according to whether or not they required hospital admission. STATA 16 was used. Results: n: 1764 patients, 958 of whom were male (54%). The median age was 56 months (IQR, 17- 116). Overall, 789 patients had an underlying disease (46%), the most frequent of which were hematology-oncology disease in 215 patients (12%), neurological disease in 103 (6%), chronic lung disease in 68 (4%), congenital heart disease in 65 (4%), and a genetic syndrome in 57 (3%); 292 were immunosuppressed (17%). Overall, 1319 patients (79%) had COVID-19-related symptoms and 591 (34%) required hospital admission. A coinfection with other respiratory viruses was observed in 33 patients (2%). Intensive care admission due to COVID-19 was required in 22 patients (1.3%) and 8 (0.5%) died with COVID-19. In univariate analysis, the presence of comorbidities, viral coinfecton, and immunosuppression were statistically significantly associated with the need for hospitalization. A history of two or more doses of the SARSCoV2 vaccine was a protective factor against hospital admission in children older than 3 years. In the multivariate model, patients younger than 3 years (OR 6.5, 95% CI 1.2-36.8, p 0.03), with comorbidities (OR 2.04, 95%CI 1.7-3.3, p 0.00) and immunocompromised hosts (OR 2.89, 95% CI 2.1-4.1, p 0.00) had a higher risk of hospital admission. When adjusting for the remaining variables, having received two or more doses of the vaccine was found to be a protective factor against hospital admission (OR 0.65, 95% CI 0.49-0.87, p<0.01). Conclusions: In this prospective cohort study of children with a confirmed diagnosis of COVID-19, symptomatic disease predominated. Thirty-four percent of the patients were admitted for COVID-19. Vaccination with two or more doses was a protective factor against hospitalization in the multivariate model. In addition, age younger than 3 years, previous comorbidities, and immunosuppression were statistically associated with hospital admission (AU)

Carcinomatosis peritoneal tras nefrectomía parcial laparoscópica en carcinoma de células renales: nuestra experiencia y revisión de la literatura / Peritoneal carcinomatosis after partial nephrectomy for renal cell carcinoma: Our experience and literature review

Objetivo: La carcinomatosis peritoneal asociada al carcinoma de células renales es una entidad infrecuente, normalmente asociada a grandes masas renales, siendo muy rara su presentación tras la cirugía de tumores renales localizados. Nuestro objetivo es revisar la literatura y analizar los factores implicados en el desarrollo de carcinomatosis peritoneal tras nefrectomía parcial laparoscópica en tumores localizados.Material y métodos: Presentamos nuestra experiencia con 2 casos de carcinomatosis peritoneal tras cirugía parcial laparoscópica. Realizamos revisión de la literatura y analizamos los factores asociados al desarrollo de carcinomatosis peritoneal tras cirugía parcial laparoscópica en carcinoma de células renales.Resultados: Entre 2005-2018 en nuestro servicio fueron sometidos a nefrectomía parcial laparoscópica 225 pacientes por neoplasia renal localizada. Dos pacientes desarrollaron carcinomatosis peritoneal en el seguimiento, uno al año y medio de la cirugía y un segundo caso a los 7 años. Pocos casos de carcinomatosis peritoneal tras cirugías de neoplasia renal han sido descritos en la literatura, estando más frecuentemente asociados a grandes masas renales, con múltiples metástasis al diagnóstico, siendo el pronóstico infausto. Entre los factores implicados en su desarrollo pueden estar la diseminación de células tumorales durante la cirugía, la extensión tumoral directa o la metástasis por vía hematógena.Conclusiones: La carcinomatosis peritoneal tras nefrectomía parcial laparoscópica constituye un evento muy raro, pero que debe ser tenido en cuenta y, dado que es el único factor en el que podemos influir, extremar al máximo las precauciones durante el acto quirúrgico, siguiendo los principios oncológicos. (AU)

Objective: Peritoneal carcinomatosis associated with renal cell carcinoma is an infrequent entity, usually associated with large renal masses, and with a very rare presentation after surgery of localized renal tumors. Our objective is to review the literature and analyze the factors involved in the development of peritoneal carcinomatosis after laparoscopic partial nephrectomy in localized tumors.Material and methods: We present our experience with two cases of peritoneal carcinomatosis after laparoscopic partial nephrectomy. We reviewed the literature and analyzed the factors associated with the development of peritoneal carcinomatosis after laparoscopic partial surgery in renal cell carcinoma.Results: Between 2005-2018, 225 patients underwent laparoscopic partial nephrectomy for localized renal neoplasia in our service. Two patients developed peritoneal carcinomatosis during follow-up, at 1.5 and 7 years after surgery. Few cases of postoperative peritoneal carcinomatosis for renal neoplasia have been described in the literature, being more frequently associated with large renal masses, with multiple metastases at diagnosis, with a poor prognosis. The dissemination of tumor cells during surgery, direct tumor extension or metastasis by hematogenous route, are among the factors involved in the development of this condition.Conclusions: Peritoneal carcinomatosis after laparoscopic partial nephrectomy constitutes a very rare event. However, it should be taken into consideration, and, since it is the only factor we can influence, we must maximize precautions during the surgical act, following oncological principles. (AU)

Two patients developed peritoneal carcinomatosis during follow-up, at 1.5 and 7 years after surgery. Few cases of postoperative peritoneal carcinomatosis for renal neoplasia have been described in the literature, being more frequently associated with large renal masses, with multiple metastases at diagnosis, with a poor prognosis. The dissemination of tumor cells during surgery, direct tumor extension or metastasis by hematogenous route, are among the factors involved in the development of this condition. CONCLUSIONS: Peritoneal carcinomatosis after laparoscopic partial nephrectomy constitutes a very rare event. However, it should be taken into consideration, and, since it is the only factor we can influence, we must maximize precautions during the surgical act, following oncological principles.

Influence of double J stent in the complications of ureterovesical anastomosis during kidney transplantation.

INTRODUCTION: Complications arising from ureterovesical anastomosis in kidney transplantation have an important influence on the success of the procedure. The most serious and frequent complications are fistula and stenosis of the ureterovesical junction. The placement of double J stents in anastomosis is currently recommended to reduce these complications. OBJECTIVE: The aim of the study is to evaluate whether the placement of a DJ stent affects complications of anastomosis. MATERIAL AND METHODS: Retrospective analysis of 697 patients treated with cadaveric donor renal transplant in our center from 1999 to 2018 was performed. Results were compared according to double J stent placement and the surgical technique employed for anastomosis. RESULTS: Transplantation was performed without DJ placement in 51.7% of the patients, compared to 48.3% who were treated with DJ stent placement. The most commonly used technique was Lich-Gregoir. Ureterovesical fistula occurred in 5% of cases, and ureterovesical stenosis in 4.2%. DJ stent behaved as a protective factor for ureterovesical fistula but did not significantly influence the development of stenosis. The Taguchi technique greatly increased the risk of developing both ureterovesical fistula and stenosis. The incidence of stenosis and fistula was significantly higher when the Taguchi technique was combined with no DJ stent placement. CONCLUSION: DJ stent placement acts as a protective factor for ureterovesical stenosis complications. The results of our study seem to agree with current literature.

Crown Reconstruction of Erosive Wear Using High-viscosity Glass Ionomer Cement: A Case Report.

The aim of this clinical report is to present a possible alternative treatment, with 24-month follow-up, for restoring tooth loss due to extensive erosive tooth wear. A 21-year-old male patient, complaining of intense sensitivity in the maxillary posterior teeth, and presenting severe wear on maxillary premolar and molar teeth due to gastroesophageal reflux, sought care in the university clinics. The planned treatment was to refer for medical treatment and perform restorations with the high-viscosity glass ionomer cement Equia Forte (GC Corporation, Tokyo, Japan), aiming to restore the dental anatomy and to consequently decrease the pain symptomatology. A silicone guide, obtained from a diagnostic waxing, was used during the restorative approach considering the patient's occlusion. After all the clinical steps of the restorative technique, an occlusal adjustment of restorations was performed. During monthly recalls up to 24 months, the treatment was stable and in service. In addition, the patient reported no pain and improved chewing, leading to a better quality of life.

Influencia del catéter doble J en las complicaciones de la anastomosis vesicoureteral realizada durante el trasplante renal / Influence of double J stent in the complications of ureterovesical anastomosis during kidney transplantation

Introducción: Las complicaciones surgidas de la anastomosis vesicoureteral en el trasplante renal influyen de forma importante en el éxito del trasplante; siendo las más graves y frecuentes la fístula y la estenosis de la unión ureterovesical. Actualmente se recomienda la colocación de catéteres doble J en esta anastomosis para reducir estas complicaciones.Objetivo: El objetivo del estudio es evaluar si la colocación de un CDJ influye en las complicaciones de esta anastomosis.Material y métodosSe ha realizado un análisis retrospectivo de 697 pacientes tratados con trasplante renal de donante cadáver en nuestro centro desde 1999 hasta 2018; y se ha comparado los resultados en función del uso o no de catéter doble J y la técnica quirúrgica realizada en la anastomosis.Resultados: En el 51,7% de los pacientes no se colocó CDJ; frente a un 48,3% en los que sí se colocó. La técnica más utilizada fue Lich-Gregoir. Se produjo fístula ureterovesical en un 5% de casos, y estenosis ureterovesical en un 4,2%. El CDJ se comportó como factor protector de fístula ureterovesical, pero no influyó significativamente en el desarrollo de estenosis. La técnica de Taguchi multiplicó el riesgo de desarrollar tanto fístula como estenosis ureterovesical. La incidencia de estenosis y de fístula fue significativamente mayor al combinar la técnica de Taguchi con la ausencia de catéter.Conclusión: El CDJ actúa como factor protector para las complicaciones de la estenosis ureterovesical. Los resultados de nuestro estudio parecen ir en concordancia con la literatura actual. (AU)

Online quality and readability assessment of Early childhood caries information available on websites from distinct countries: A cross-sectional study.

AIM: To assess the quality and readability of ECC-related Web information available in English, Spanish, and Brazilian Portuguese language. METHODS: This study assessed the quality and readability of information related to ECC in three different languages found on the most popular Internet search engines worldwide. Websites were retrieved from different search engines using specific strategies. DISCERN questionnaire, JAMA benchmark criteria, and language-based readability formulas were used by two independent investigators to evaluate the quality and readability of websites. Also, contents were categorised according to aetiology, prevention, and treatment of ECC. The statistical analysis was performed using Spearman's rank correlation coefficient, hierarchical clustering analysis by Ward's minimum variance method, and Mann-Whitney U test. P values < 0.05 were considered significant. CONCLUSION: ECC-related digital contents were considered simple, accessible and of poor quality, independently of their language and authorship. These findings indicate the importance of professional counseling to empower parents in selecting and consuming adequate information towards the improvement of children's oral health.
