Aplicabilidad del índice de fragilidad hepática en pacientes cirróticos evaluados para trasplante / Applicability of the liver frailty index in cirrhotic patients evaluated for transplantation

Introducción. En las últimas décadas se han desarrollado diferentes scores y modelos para predecir el pronóstico en pacientes con enfermedad hepática crónica avanzada. Los más reconocidos y utilizados son el sistema de estadificación de Child-Pugh (CP) y el score de MELD, pero estos carecen de herramientas para evaluar objetivamente otros factores pronósticos. Por este motivo, se ha incorporado el concepto de fragilidad a la hepatología clínica. El objetivo de este artículo es examinar la aplicabilidad del índice de fragilidad hepática (IFH) en pacientes con cirrosis evaluados para trasplante hepático en Uruguay. Metodología. Estudio observacional, descriptivo y retrospectivo en el Servicio de Enfermedades Hepáticas del Hospital Central de las Fuerzas Armadas (HCFFAA) de enero de 2018 a diciembre de 2021. Resultados. Se evaluaron un total de 78 pacientes, excluyéndose 19 de estos, culminando con una muestra final de 59 pacientes. La edad media fue de 52 años, siendo el 66 % hombres. La principal etiología de la cirrosis fue la alcohólica, y la comorbilidad más frecuente fue el sobrepeso/obesidad (66 %). La media de IFH fue de 4,03 ± 0,45. El 90 % de los pacientes eran prefrágiles, el 10 % frágiles y ningún paciente fue clasificado como no frágil. El 76 % presentaba un estadio avanzado de la enfermedad al momento de la evaluación 42 % CP estadio B, 34 % CP C, 24 % CP A, con una media de MELD-Na de 17,8 ± 7,6. El 17 % tuvo complicaciones infecciosas. La mortalidad global (n=78) fue del 12 %, y la de los pacientes con IFH calculado fue del 22 %. Conclusiones. El cálculo del IFH es realizable en cirróticos como herramienta objetiva que brinda una mirada integral del paciente. A mayor severidad de la cirrosis, mayor es el IFH. Sin embargo, este índice no parece ser un predictor de la eventual realización del trasplante hepático, ni de muerte en lista de espera en nuestros pacientes.

Introduction. In recent decades, several scores and models have been proposed to predict prognosis in patients with advanced chronic liver disease. The most recognized and used are the Child-Pugh (CP) and the Model for End-stage Liver Disease (MELD) scores, but they lack tools to objectively evaluate other prognostic factors. For this reason, the concept of fragility has been incorporated into clinical hepatology. The objective of this study was to evaluate the applicability of the liver frailty index (LFI) in patients with cirrhosis evaluated for liver transplantation in Uruguay. Methodology. Observational, descriptive and retrospective study at the Hospital Central de las Fuerzas Armadas (HCFFAA) Liver Disease Service from January 2018 to December 2021. Results. A total of 78 patients were evaluated, 19 were excluded, culminating in a final sample of 59 patients. The mean age was 52 years, with 66% being men. The main etiology of cirrhosis was alcoholic and the most frequent comorbidity was overweight/obesity (66%). The mean LFI was 4.03 ± 0.45. 90% of patients were pre-fragile, 10% were fragile, and no patient was classified as non-fragile. 76% had an advanced stage of the disease at the time of evaluation: 42% CP stage B, 34% CP C, 24% CP A, with a mean MELD-Na of 17.8 ± 7.6. 17% had infectious complications. Overall mortality (n=78) was 12%, and that of patients with calculated LFI was 22%. Conclusions. The LFI can be calculated in cirrhotic patients, and it is an objective tool that provides a comprehensive view of the patient. LFI depends on the severity of the cirrhosis. However, this index is not a predictor of liver transplantation or death on the waiting list in our patients.

Diagnosis of Celiac Disease after Starting Antitubercular Medication: A Case Report

We present the case of a young patient from Argentina living in a rural area without any relevant medical history. He consulted the emergency department after blunt chest trauma, and during trauma studies, images compatible with pulmonary tuberculosis were found, a diagnosis made incidentally. After starting treatment, he exhibited gastrointestinal symptoms such as diarrhea, abdominal pain, and weight loss, which were initially considered an adverse effect of treatment with rifampin/isoniazid/pyrazinamide/ethambutol (RHZE). Upon completing the first phase of treatment and suspending the medication, the symptoms improved, and the bacilloscopies were negative. Subsequently, the severity of the symptoms drew attention. Additional paraclinical tests were performed with malabsorptive diarrhea results, considering the patient's origin and the fact that his diet included products that he grew himself without prior exposure to gluten. Celiac disease is suspected, and antibodies and biopsy results compatible with this entity were obtained. When reviewing the association of symptom onset with the RHZE/pyridoxine treatment, we found these medications may have wheat-based excipients, which explains the worsening of symptoms, not due to the gastrointestinal adverse effects of the antibiotic but its excipients. Finally, the case was analyzed, tuberculosis was ruled out, and treatment was suspended, refocusing the therapeutic effort on recovering the patient's nutritional status. Subsequently, no other hospital admissions were recorded, and he remained respiratorily asymptomatic, with weight gain and nutritional recovery.

Se presenta el caso de un paciente joven, proveniente de Argentina y residente de un área rural, sin ningún antecedente médico a resaltar. Consultó al servicio de urgencias después de un trauma cerrado de tórax y durante los estudios de trauma se encontraron imágenes compatibles con tuberculosis pulmonar, diagnóstico realizado de manera incidental. Luego del inicio de tratamiento presentó síntomas gastrointestinales dados por diarrea, dolor abdominal y pérdida de peso, lo que inicialmente se consideró un efecto adverso al tratamiento con rifampicina/isoniazida/pirazinamida/etambutol (RHZE). Al completar la primera fase del tratamiento y suspender la medicación mejoraron los síntomas, además de que las baciloscopias fueron negativas. Posteriormente, llamó la atención la gravedad de los síntomas, por lo que se realizaron paraclínicos adicionales con resultados a favor de diarrea malabsortiva; teniendo en cuenta la procedencia del paciente y el hecho de que basaba su dieta en productos que él mismo cultivaba, sin haber exposición previa al gluten. Se sospecha enfermedad celíaca, y se obtuvieron anticuerpos y resultados en la biopsia compatibles con esta entidad. Al revisar la asociación de inicio de síntomas con el uso de tratamiento de RHZE/piridoxina, se observa que estos medicamentos pueden tener excipientes a base de trigo, lo que explica el empeoramiento de los síntomas, no por efectos adversos gastrointestinales del antibiótico sino por sus excipientes. Finalmente, se analizó el caso, se descartó tuberculosis y se suspendió el tratamiento, redirigiendo el esfuerzo terapéutico hacia la recuperación del estado nutricional del paciente. Posteriormente, no se registran otros ingresos hospitalarios, continúa asintomático respiratorio, con ganancia de peso y recuperación nutricional.

Introduction. The objective of this study is to describe the characteristics of dog bite injuries in children seen at a children's hospital in Bolivia. Population and methods. This was an observational, retrospective study in patients seen between 2017 and 2021. Results. A total of 769 patients were studied. Dog bite injuries accounted for 5.6% of emergency visits and 0.8% of hospitalizations. They were more frequent in children younger than 5 years (55.1%), in whom the following were observed: greater injury severity (p = 0.008), history of animal provocation (p = 0.048), known attacking animal (p < 0.036), domestic accident (p = 0.021), greater frequency of post-exposure prophylaxis with anti-rabies serum (p = 0.005), and maxillofacial area as the main region involved (p < 0.001). There were 3 deaths due to human rabies and 1 due to hypovolemic shock. Conclusion. Dog bite injuries are a frequent cause of visit to the emergency department and hospitalization in pediatrics and have specific characteristics in children younger than 5 years.

Resultados maternos y fetales en mujeres embarazadas con enfermedad renal crónica basada en la tasa de filtración glomerular / Maternal And Fetal Outcomes In Pregnant Women With Chronic Kidney Disease Based On Glomerular Filtration Rate

Introducción: el embarazo causa adaptaciones en el riñón, tanto en anatomía como en función, para mantener el entorno extracelular, hemodinámico y hormonal. Sin embargo, estos pueden no llevarse a cabo de manera completamente óptima en presencia de enfermedad renal. El objetivo era estudiar la relación entre la enfermedad renal y los resultados maternos de fetal durante el embarazo, asociado con un rechazo por paciente y/o en relación con el tratamiento especializado. Material y métodos: estudio observacional y retrospectivo en una serie de casos, revisando 134 archivos de pacientes embarazadas con cierto grado de enfermedad renal antes del embarazo. Los resultados maternos registrados fueron: enfermedad hipertensiva durante el embarazo, deterioro renal agudo, necesidad de terapia de sustitución renal y en productos: prematuridad, restricción del crecimiento intrauterino, muerte fetal y aborto espontáneo. Resultados: Resultados maternos: tasa media de filtración glomerular (GFR) de 58.23 ml/min, aumento de peso de 7 kg; La preeclampsia fue diagnosticada en 92 mujeres (55 severas). 46 pacientes mostraron lesión renal aguda, 40 se resolvieron conservativamente; 1 requirió diálisis peritoneal y 15 hemodiálisis (con una decisión retrasada un promedio de un mes por rechazo por paciente y/o pariente). La resolución del embarazo fue por cesárea en 111 pacientes; Nacieron 116 productos antes de las 37 semanas de gestación, con un peso promedio de 1910 g, 94 mostraron restricción del crecimiento intrauterino. Conclusión: la enfermedad renal influyó directamente en el mayor número de resultados adversos maternos y fetales cuando se rechazó la atención médica especializada. Existe una correlación entre el ligero estado de Davison con los estados I, II y IIIA de Kdigo en el análisis de correspondencia

Introduction: Pregnancy causes adaptations in the kidney, both in anatomy and function, to maintain the extracellular, hemodynamic and hormonal environment. However, these may not be carried out completely optimally in the presence of kidney disease. The objective was to study the relation between kidney disease and maternal-fetal outcomes during pregnancy, associated with a rejection by patient and/or relative to specialized treatment. Material and Methods: Observational, retrospective study in a series of cases, reviewing 134 files of pregnant patients with some degree of kidney disease prior to pregnancy. Maternal outcomes recorded were: hypertensive disease during pregnancy, acute renal deterioration, need for renal substitution therapy, and in products: prematurity, restriction of intrauterine growth, fetal death and miscarriage. Results: Maternal outcomes: mean glomerular filtration rate (GFR) of 58.23ml/min, weight gain of 7 kg; preeclampsia was diagnosed in 92 women (55 severe). 46 patients showed acute renal lesion, 40 were conservatively resolved; 1 required peritoneal dialysis and 15 hemodialysis (with decision delayed an average of one month by rejection by patient and/or relative). Resolution of pregnancy was by cesarean in 111 patients; 116 products were born before 37 weeks of gestation, with average weight of 1910 g, 94 showed restriction of intrauterine growth. Conclusion: Kidney disease directly influenced the greater number of adverse maternal and fetal outcomes when specialized medical care was rejected. There is a correlation between slight Davison state with states I, II and IIIa of KDIGO in correspondence analysis.

Third National Registry of Cardiac Rehabilitation Programs in Mexico (RENAPREC III-2022) / Tercer Registro Nacional de Programas de Rehabilitación Cardiaca en México (RENAPREC III-2022)

Abstract Introduction: In Mexico, cardiac rehabilitation (CR) as an interdisciplinary intervention with therapeutic impact in patients with heart disease is growing. There is the need to know actual conditions of CR in our country. Objectives: The objective of this National Registry is to follow-up those existing and new CR units in Mexico through the comparison between the two previous registries, RENAPREC-2009 and RENAPREC II-2015 studies. This is a descriptive study focused on diverse CR activities such as assistance training, and certification of health professionals, barriers, reference, population attended, interdisciplinarity, permanence over time, growth prospects, regulations, post-pandemic condition, integrative characteristics, and scientific research. Results: Data were collected from 45 CR centers in the 32 states, 75.5% are private practice units, 67% are new, 33% were part of RENAPREC II-2015, and 17 have continued since 2009. With a better distribution of CR units along the territory, the median reference of candidates for CR programs is 9% with a significant reduction into tiempo of enrollment to Phase II admission (19 ± 11 days). Regarding to previous registries, the coverance of Phases I, II, and III is 71%, 100%, and 93%, respectively; and a coverance increases in evaluation, risk stratification, and prescription, more comprehensive attendance and prevention strategies. Conclusions: CR in Mexico has grown in the past 7 years. Even there is still low reference and heterogeneity in specific processes, there are strengths such as interdisciplinarity, scientific professionalization of specialists, national diversification, and an official society that are consolidated over time.

Consenso colombiano de la enfermedad inflamatoria intestinal pediátrica

está disponible en el texto completo

Introduction: Pediatric ulcerative colitis (CUP), pediatric Crohn's disease (PCD), and pediatric inflammatory bowel disease not classifiable (PIDNCID) have clinical and psychosocial particularities that differentiate them from those of adults and may condition different therapeutic approaches due to possible nutritional, growth and developmental repercussions, representing a challenge for the pediatrician and gastroenterologist. Objective: Develop expert consensus evidence-based recommendations for the timely and safe diagnosis and treatment of Pediatric Inflammatory Bowel Disease (PID) in children under 18 years of age for professionals caring for these patients and healthcare payers. Methodology: Through a panel of experts from the Colombian College of Pediatric Gastroenterology, Hepatology and Nutrition (COLGAHNP) and a multidisciplinary group, 35 questions were asked regarding the clinical picture, diagnosis, and treatment of PID. Through a critical review and analysis of the literature with particular emphasis on the main clinical practice guidelines (CPGs), randomized clinical trials (RCTs), and meta-analyses of the last ten years, from which the experts made 77 recommendations that responded to each of the research questions with their respective practical points. Subsequently, each of the statements was voted on within the developer group, including the statements that achieved > 80%. Results: All statements scored > 80%. PID has greater extension, severity, and evolution towards stenosis, perianal disease, extraintestinal manifestations, and growth retardation compared to adult patients, so its management should be performed by multidisciplinary groups led by pediatric gastroenterologists and prepare them for a transition to adulthood. Porto's criteria allow a practical classification of PID. In CPE, we should use the Paris classification and perform ileocolonoscopy and esophagogastroduodenoscopy, since 50% have upper involvement, using the SES-CD (UCEIS/Mayo in CUP) and taking multiple biopsies. Initial labs should include inflammatory markers and fecal calprotectin and rule out intestinal infections. Treatment, induction, and maintenance of PID should be individualized and decided according to risk stratification. Follow-up should use PCDAI and PUCAI for the last 48 hours. Immunologists and geneticists should evaluate patients with early and infantile PID. Conclusion: A consensus guideline is provided with evidence-based recommendations on timely and safe diagnosis and treatments in patients with ILD.

Manejo de embarazos únicos con diagnóstico antenatal de vasa previa / Management of singleton pregnancies with prenatal diagnosis of vasa previa

Introducción: vasa previa (VP) corresponde al paso de los vasos umbilicales por las membranas amnióticas, sin protección de gelatina de Wharton o placenta, antes de la presentación fetal, sobre el orificio cervical interno. Pese a su baja incidencia, el diagnóstico prenatal es relevante por las graves consecuencias que puede tener esta patología en caso de no ser diagnosticada. El objetivo de esta revisión es presentar la evidencia disponible para el manejo de embarazadas con diagnóstico antenatal de VP. Materiales y métodos: analizamos todos los estudios publicados (prospectivos, retrospectivos y reporte de casos) entre los años 1999 y 2023, con diagnóstico VP en embarazo único, reportando la edad gestacional de interrupción y el resultado neonatal. Resultados: incluimos 19 investigaciones (18 en la búsqueda primera y una adicional por relevancia). Las pacientes con manejo intrahospitalario desde las 34 semanas tuvieron mayor latencia al parto, mejores resultados neonatales y menor tasa de cesárea de urgencia que las pacientes con manejo ambulatorio. La edad gestacional de interrupción es variable entre los estudios, sin embargo, no se evidenció beneficio de interrupción a las 34 semanas comparado con manejo expectante hasta las 37 semanas de edad gestacional. Conclusión: existiría beneficio de hospitalización entre las 32-34 semanas en mujeres con diagnóstico de VP, siendo razonable la interrupción cercana a las 37 semanas por cesárea electiva.

Introduction: vasa previa (VP) corresponds to the passage of the umbilical vessels through the amniotic membranes, without the protection of Wharton's gelatin or placenta, in front of the fetal presentation, over the internal cervical os. Despite its low incidence, prenatal diagnosis is relevant due to the severe consequences of this pathology if the diagnosis is missed. This review presents the available evidence for pregnant women's management with an antenatal diagnosis of VP. Materials and methods: we analyzed all the studies published (prospective, retrospective, and case reports) between 1999 and 2023, with a diagnosis of VP in a single pregnancy, reporting gestational age at delivery and neonatal outcome. Results: We included 19 investigations (18 in the first search and another for relevance). Patients with in-hospital management from 34 weeks had a more extended latency period until delivery, better neonatal outcomes, and a lower rate of emergency cesarean section than patients with outpatient management. The gestational age at birth is variable between the studies; however, no benefit of delivery at 34 weeks was evidenced compared with expectant management until 37 weeks of gestational age. Conclusion: there would be a benefit of hospitalization between 32-34 weeks in women diagnosed with VP, being reasonable to schedule the delivery close to 37 weeks by elective cesarean section.

Description of changes in clinical outcomes following the implementation of an antibiotic stewardship program in a level IV hospital / Descripción del cambio en desenlaces clínicos posteriores a la implementación de un programa de gestión de antibióticos en un hospital de cuarto nivel de atención en salud

Introduction. Inadequate prescription of antibiotics has been recognized as a public health problem by the World Health Organization. In this context, antibiotic stewardship programs have been implemented as a tool to mitigate its impact. Objective. To describe the changes in clinical outcomes after the implementation of an antibiotic stewardship program in a level IV hospital. Materials and methods. We conducted a unique cohort study of patients hospitalized for infectious pathologies that were treated with antibiotics in an advanced medical facility. We collected the clinical history before the implementation of the antibiotic stewardship program (2013 to 2015) and then we compared it to the records from 2018 to 2019 collected after the implementation of the program. We evaluated changes in clinical outcomes such as overall mortality, and hospital stay, among others. Results. We analyzed 1,066 patients: 266 from the preimplementation group and 800 from the post-implementation group. The average age was 59.2 years and 62% of the population was male. Statistically significant differences were found in overall mortality (29% vs 15%; p<0.001), mortality due to infectious causes (25% vs 9%; p<0.001), and average hospital stay (45 days vs 21 days; p<0.001); we also observed a tendency to decrease hospital re- admission at 30 days for infectious causes (14% vs 10%; p=0.085). Conclusions. The antibiotic stewardship program implemented was associated with a decrease in overall mortality and mortality due to infectious causes, as well as in average hospital stay. Our results evidenced the importance of interventions aimed at mitigating the impact of inadequate prescription of antibiotics.

Introducción. La inadecuada prescripción de antibióticos es un problema de salud pública, reconocido por la Organización Mundial de la Salud. Los programas de gestión de antibióticos son implementados como una herramienta para mitigar su impacto. Objetivo. Describir los cambios observados en los desenlaces clínicos después de la implementación de un programa de gestión de antibióticos en un hospital de IV nivel de atención. Materiales y métodos. Se llevó a cabo un estudio de cohorte única de pacientes hospitalizados por patologías infecciosas y tratados con antibióticos en una institución médica de alta complejidad. Inicialmente, se recolectaron las historias clínicas anteriores a la implementación del programa de gestión de antibióticos (2013 a 2015) y luego se compararon con los datos obtenidos después de la implementación del programa de gestión de antibióticos de 2018 a 2019. Se evaluaron los cambios en los desenlaces clínicos como mortalidad y estancia hospitalaria, entre otros. Resultados. Se analizaron las historias clínicas de 1.066 pacientes: 266 con historia previa a la implementación del programa y 800 con historia posterior a la implementación. El promedio de edad fue 59,2 años y 62 % de la población era masculina. Se encontraron diferencias estadísticamente significativas en mortalidad global (29 Vs. 15 %; p<0,001), mortalidad por causa infecciosa (25 % Vs. 9 %; p<0,001) y promedio de estancia hospitalaria (45 Vs.21 días; p<0,001), con tendencia a disminuir nuevas hospitalizaciones en 30 días por patología infecciosa (14 Vs.10 %; p=0,085). Conclusiones. El desarrollo del programa de gestión de antibióticos se asoció con a una disminución en la mortalidad global, la mortalidad por causa infecciosa y la estancia hospitalaria. Esto demuestra la importancia de desarrollar intervenciones dirigidas a mitigar el impacto de la prescripción inadecuada de antibióticos.

Prospective evaluation of the effectiveness of combined treatment of macular edema secondary to retinal vein occlusion with intravitreal bevacizumab and dexamethasone implants / Estudo intervencionista prospectivo para avaliar a eficácia da associação do bevacizumabe intravítreo ao implante de dexametasona para edema macular secundário à oclusão da veia retiniana

ABSTRACT Purpose: To evaluate the effectiveness of in­­­travitreal bevacizumab injections following a single dexamethasone implant in the treatment of macular edema secondary to branch and central retinal vein occlusion. Methods: This was a prospective interventional non-comparative study, 44 eyes of patients with naïve macular edema related to branch and central retinal vein occlusion were treated with a dexamethasone implant. Patients were followed-up at four-week intervals from the second to the sixth month. If persistent or recurrent macular edema occurred during this period, the patient was treated with intravitreal bevacizumab injections on an as-needed basis. The outcome measures were best-corrected visual acuity and central macular thickness changes. Results: The mean best-corrected visual acuity changed from 0.97 ± 0.33 LogMAR at baseline to 0.54 ± 0.40 at the six-month post-implant examination (p<0.00001). Improvement ≥3 Snellen lines were seen in 20 eyes (45.54%). The mean central macular thickness at baseline was 670.25 ± 209.9 microns. This had decreased to 317.43 ± 112.68 microns at the six-month follow-up (p<0.00001). The mean number of intravitreal bevacizumab injections received in the six months post-implant was 2.32. The mean time from dexamethasone implant to first anti-VEGF injection was 3.45 months. Conclusions: Intravitreal bevacizumab injections following a single dexamethasone implant were found to improve best-corrected visual acuity and central macular thickness in patients with macular edema due to branch and central retinal vein occlusion at six months, with few intravitreal injections required.

RESUMO Objetivo: Avaliar a eficácia da combinação de in­jeções intravítreas de bevacizumabe em olhos com edema macular secundário à oclusão de ramo e da veia central da retina após um único implante de dexametasona. Métodos: Foi realizado um estudo prospectivo intervencionista não comparativo com 44 olhos de pacientes com edema macular relacionado à oclusão de ramo e veia central da retina, sem tratamento prévio e tratados com um único implante de dexametasona, que foram acompanhados em intervalos de quatro semanas do segundo ao sexto mês. Se fosse constatado edema macular persistente ou recorrente durante esse período, os pacientes eram tratados com injeções intravítreas de bevacizumabe em um regime ajustado conforme a necessidade. Foram estudadas a melhor acuidade visual corrigida e alterações da espessura macular central. Resultados: A média da melhor acuidade visual corrigida mudou de 0,97 ± 0,33 LogMAR iniciais para 0,54 ± 0,40 no exame de 6 meses (p<0,00001). Vinte olhos (45,54%) melhoraram 3 linhas de Snellen ou mais. A média da espessura macular central inicial foi de 670,25 ± 209,9 μm e diminuiu para 317,43 ± 112,68 μm na visita de 6 meses (p<0,00001). O número médio de injeções intravítreas de bevacizumabe em 6 meses foi de 2,32 e o tempo médio entre o implante de dexametasona e a primeira injeção de anti-VEGF foi de 3,45 meses. Conclusão: Injeções intravítreas de bevacizumabe após um único implante de dexametasona podem proporcionar um aumento da melhor acuidade visual corrigida e diminuição da espessura macular central aos 6 meses em pacientes com edema macular devido à oclusão de ramo e da veia central da retina, com poucas injeções intravítreas.

Objective: To describe the results of the evaluation in posgrado, through the educational modality at distance during the third regrowth of the pandemic of COVID-19. Methodology: A cross-sectional descriptive observational study was conducted between June and July 2021 at the Faculty of Stomatology, University of Medical Sciences of Santiago de Cuba. The following units of analysis were considered: teaching units, students (residents), the population consisted of 146 residents in the first year of specialization, a random sample was selected (n= 96). The variables studied were the results of the evaluations of each didactic unit and the general evaluation of the module (excellent, good, fair, and poor), level of difficulty (very difficult, difficult, and no difficulty), and level of satisfaction (satisfied, moderately satisfied, and dissatisfied). The evaluation and interview registers were used as measurement instruments, respectively, and the percentage was used as a summary measure. Results: More than 70% of the residents evaluated were in the good without difficulty category and were satisfied with the distance learning modality. Conclusions: The results "excellent" predominated only in didactic unit 1 and "good" in the final evaluation of the module. The "most difficult" didactic unit was didactic unit 2. Most residents were satisfied with the distance learning modality in the postgraduate program.

Caries dental y calidad de vida de escolares de 6 a 8 años / Dental caries and quality life of schoolchildren aged 6 to 8 years

Introducción: la caries dental ocasiona dolor y alteración de la salud. La calidad de vida se refiere a la percepción de uno con base en su situación física, emocional y social. Objetivo: analizar la percepción de la calidad de vida en un grupo de escolares con caries. Metodología: 270 escolares de 6-8 años de edad con y sin experiencia de lesiones cariosas contestaron con sus padres un cuestionario basado en la Scale of Oral Health Outcomes (SOHO). Las respuestas se registraron con escala de tipo Likert. Se obtuvieron frecuencias, porcentajes, promedios y desviación estandar. Se compararon los grupos con chi cuadrada y t de Student, y se calculó la razón de momios (RM). Resultados: el 58% presentó experiencia de caries. El 64% de los escolares con caries informó que tenía antecedentes de dolor dentario y la media en los dominios sobre funciones bucales y relación familiar fue mayor para los escolares con caries (p = 0.001). Tener caries fue determinante para presentar dificultades para comer: RM 8.7 (intervalo de confianza del 95% [IC 95%] 4.7-16); beber: RM 5.9 (IC 95% 3.4-10); dormir: RM 5.3 (IC 95% 3.1-9); jugar: 5.2 (IC 95% 2.7-10), p < 0.001. Desde la autopercepción del escolar, el 87% manifestó no sentirse contento por la presencia de caries. Conclusiones: la percepción de los escolares y padres del grupo con experiencia de caries dental mostró deterioro en la calidad de vida.

Background: Dental caries causes pain and alteration of integral health. Quality of life refers to oneself's perception of their physical, emotional and social situation. Objective: To analyze the perception of quality of life in a group of schoolchildren with caries. Methodology: 270 schoolchildren aged 6-8 years with and without experience of carious lesions, with their parents, answered a questionnaire based on the Scale of Oral Health Outcomes (SOHO). The answers were recorded with a Likert-type scale. Frequencies, percentages, averages and standard deviation were obtained. The groups were compared with chi squared and Student's t test, and odds ratios (OR) were calculated. Results: 58% presented caries experience. 64% of schoolchildren with caries reported antecedents of dental pain, and the mean in the domains on oral functions and family relationship was higher for schoolchildren with caries (p = 0.001). Having caries was determinant for eating difficulties: OR 8.7 (95% CI 4.7-16); drink: OR 5.9 (95% CI 3.4-10); sleeping: OR 5.3 (95% CI 3.1-9); play: OR 5.2 (95% CI 2.7-10), p < 0.001. From schoolchildren auto-perception 87% said they did not feel happy about their decayed teeth. Conclusions: The perception of the schoolchildren and parents belonging to the group with experience of dental caries showed deterioration in the quality of life.

ENDOMETRIAL CARCINOMA: NARRATIVE REVIEW

Endometrial cancer is the most common gynecological malignancy in developed countries and its incidence has been increasing over recent years. Symptoms include postmenopausal bleeding, abnormal vaginal bleeding, pelvic pain, and dyspareunia. Risk factors include obesity, unopposed estrogen exposure, family history of endometrial or ovarian cancer, and Lynch syndrome. Diagnosis is con?rmed through endometrial biopsy, hysteroscopy, or dilation and curettage.

Migración de catéter distal a nivel del recto como complicación de derivación ventriculoperitoneal. Reporte de caso / Catheter Migration Through the Rectum as Ventricular Peritoneal Shunt Complication. Case Report

Resumen La hidrocefalia es una entidad nosológica común que en muchos casos tiene como tratamiento de elección la derivación ventricular hacia cualquier cavidad. Dentro de las complicaciones más frecuentes, tenemos las abdominales con formación de colecciones, así como irrupción a sistema intestinal con posterior migración del mismo con presentación de sintomatología a este nivel. Presentamos el caso de un paciente con nula sintomatología abdominal y migración del catéter distal hacia el recto.

Abstract Hydrocephalus is a common nosological entity, with ventricular shunting towards any cavity as the treatment of choice in many cases. Among the most frequent complications, we have the abdominal ones with the formation of collections, as well as irruption to the intestinal system with subsequent migration of the same with presentation of symptoms at this level. We present the case of a patient with no abdominal symptoms and migration of the distal catheter towards the rectum.

Mucormicosis invasora en pacientes con COVID-19: reporte de 2 casos / Invasive mucormycosis during COVID-19 infection. Report of two cases

COVID-19 disease is associated with a significant number of opportunistic infections, including invasive fungal infections such as mucormycosis. The prevalence of the latter is rare, estimated to be between 0.005 and 1.7 per million inhabitants. Risk factors include hematological diseases, Diabetes Mellitus with poor metabolic control, solid organ transplantation, neutropenia, and prolonged administration of systemic corticosteroids. We report two males aged 60 and 75 years with pulmonary and tracheobronchial invasive mucormycosis, respectively. Both patients had a deficient metabolic control of their diabetes as a predisposing risk factor added to severe COVID-19 infection. High suspicion and early diagnosis are essential for prompt treatment, especially considering the associated high morbidity and mortality of this fungal infection.

Linfoma de Hodgkin clásico: diferentes caras, una misma entidad / Classic Hodgkin lymphoma: different faces, same entity

El linfoma de Hodgkin clásico es una neoplasia linfoide maligna derivada de las células B del centro germinal, que corresponde aproximadamente al 85 % de los casos de linfoma de Hodgkin. Esta entidad afecta principalmente a pacientes jóvenes, y cuenta con un excelente pronóstico gracias a los avances en los métodos diagnósticos para su estadificación y tratamiento. Su enfoque diagnóstico correcto y completo requiere de una historia clínica exhaustiva y una biopsia de ganglio linfático adecuada para el análisis e identificación de los hallazgos histopatológicos e inmunohistoquímicos característicos, ya que a diferencia de otros linfomas donde las células neoplásicas son una población importante o dominante, las células de Hodgkin y Reed-Sternberg generalmente representan menos del 10 % de la lesión tumoral. Aunque todavía falta mucho por entender sobre la naturaleza biológica de este linfoma y sus diferentes subtipos, en los últimos años se ha avanzado considerablemente en la comprensión de su linfomagénesis, especialmente cuando está relacionada con la infección por el virus de Epstein-Barr. Su alta heterogeneidad y posible superposición morfológica, obligan a continuar su estudio para poder identificarlo, al igual que a sus posibles diagnósticos diferenciales en aquellos casos donde se presente con una variante o patrón infrecuente. Este artículo pretende ofrecer una descripción integral resumida y actualizada sobre la fisiopatología, la clínica, el diagnóstico histopatológico con énfasis en aquellos patrones raros que podrían llegar a ser factores distractores y de confusión, y el pronóstico del linfoma de Hodgkin clásico, buscando lograr una mejor comprensión de la enfermedad

Classic Hodgkin lymphoma is a malignant lymphoid neoplasm derived from B cells in the germinal center, and accounts for approximately 85% of all Hodgkin lymphoma cases. This disease mainly affects young patients and has an excellent prognosis due to advances in diagnostic methods for staging and treatment. A correct and complete diagnostic approach requires a thorough clinical history and an adequate lymph node biopsy for the analysis and identification of characteristic histopathological and immunohistochemical findings. Unlike other lymphomas where neoplastic cells are an important or dominant population, Reed-Sternberg/ Hodgkin cells generally represent less than 10% of the tumor lesion. Although much remains to be understood about the biological nature of this lymphoma and its different subtypes, considerable progress has been made in understanding its lymphomagenesis in recent years, especially when it is related to Epstein-Barr virus infection. Its high heterogeneity and possible morphological overlap require ongoing study to identify it and its possible differential diagnoses in cases where it presents with a rare variant or pattern. This article aims to provide a comprehensive updated summary on the pathophysiology, clinical presentation, histopathological diagnosis, with emphasis on rare patterns that could become distracting and confusing factors, and prognosis of classic Hodgkin lymphoma, seeking to achieve a better understanding of the disease

Communication of medical errors in a simulated clinical scenario. Experience with a pediatric residency group / Comunicação de erros médicos em cenário clínico simulado. Experiência com residentes em Pediatria

ABSTRACT Objective: To determine the performance of groups of pediatric residents from a Buenos Aires hospital, in terms of correct recognition and communication of a medical error (ME), in a high-fidelity simulation scenario. To describe the reactions and communication attempts following the ME and the self-perception by the trainees before and after a debriefing. Methods: Quasi-experimental uncontrolled study conducted in a simulation center. First- and third-year pediatric residents participated. We designed a simulation case in which an ME occurred and the patient deteriorated. During the simulation, participants had to provide information on communicating the ME to the patient's father. We assessed communication performance and, additionally, participants completed a self-perception survey about ME management before and after a debriefing. Results: Eleven groups of residents participated. Ten (90.9%) identified the ME correctly, but only 27.3% (n=3) of them reported that a ME had occurred. None of the groups told the father they were going to give him important news concerning his son's health. All 18 residents who actively participated in this communication completed the self-perception survey, with an average score before and after debriefing of 5.00 and 5.05 (out of 10) (p=0.88). Conclusions: We observed a high number of groups that recognized the presence of a ME, but the communication action was substantially low. Communication skills were insufficient and residents' self-perception of error management was regular and not modified by the debriefing.

RESUMO Objetivo: Determinar o desempenho de grupos de residentes pediátricos de um hospital de Buenos Aires, em termos de reconhecimento e comunicação correta de um erro médico (EM),em cenário de simulação. Descrever as reações e tentativas de comunicação após o EM e a autopercepção pelos estagiários antes e depois de um questionário. Métodos: Estudo quase experimental não controlado realizado em centro de simulação. Participaram residentes pediátricos do primeiro e terceiro anos. Concebeu-se um caso de simulação em que ocorreu um EM com deterioração de um paciente. Durante a simulação, os participantes tiveram que fornecer informações relacionadas à comunicação do EM ao pai do paciente. Avaliou-se o desempenho da comunicação e, adicionalmente, os participantes completaram um inquérito de autopercepção sobre a gestão da EM, antes e depois de um questionário. Resultados: Onze grupos de residentes participaram. Dez (90,9%) identificaram corretamente o EM, mas apenas 27,3% (n=3) deles comunicaram que havia ocorrido o EM. Nenhum dos grupos disse ao pai que iria dar notícias importantes sobre a saúde do seu filho. Todos os 18 residentes que participaram ativamente da comunicação completaram o questionário de autopercepção com uma pontuação média antes e depois do questionário de 5,00 e 5,05 (máximo: 10 pontos) (p=0,88). Conclusões: Observamos elevado número de grupos que reconheceram a presença de um EM, mas a ação de comunicação foi rara. A capacidade de comunicação foi insuficiente e a autopercepção da gestão de erros por parte dos residentes foi regular, não sendo modificada pelo debriefing.

Eficacia del atenolol para prevenir la hipertensión perioperatoria en pacientes hipertensos durante la colecistectomía endoscópica

Introducción: La hipertensión perioperatoria constituye una de las principales alteraciones detectadas durante la colecistectomía video endoscópica. Se presume del efecto protector que tiene el atenolol con su acción beta bloqueadora en reducir esta condición morbosa. Objetivo: Evaluar la eficacia del atenolol en prevenir la hipertensión perioperatoria durante la colecistectomía video endoscópica en la unidad quirúrgica del Hospital Clínico Quirúrgico "Lucía Íñiguez Landín" de Holguín Método: Se realizó un estudio observacional, analítico, longitudinal y prospectivo de tipo cohorte con dos grupos paralelos de estudio, uno de tratamiento y un grupo control, desde enero a diciembre de 2018. El universo estuvo constituido por los 697 pacientes (N=697) atendidos en la consulta de evaluación preoperatoria y se tomó como muestra a 183 hipertensos (n=183) que se operaron por cirugía video endoscópica de litiasis vesicular, de ellos aleatorizados 95 al grupo de tratamiento con atenolol y 88 al grupo control. A los pacientes del grupo tratamiento se les administró atenolol 25 mg diarios durante 15 días antes de la cirugía. Las variables principales que se monitorizaron fueron las presiones arteriales sistólica, diastólica y media, y se emplearon indicadores para evaluar la efectividad del tratamiento. Resultados: Las presiones arteriales preoperatorias disminuyeron de forma significativa en el grupo de tratamiento con atenolol. La hipertensión perioperatoria fue más frecuente en el grupo control. El atenolol es un bloqueador selectivo de los receptores beta 1, ejerce su efecto hipotensor a nivel central al deprimir los centros cardiovasculares simpáticos como el vasomotor bulbar. Conclusiones: El tratamiento con atenolol fue eficaz en reducir la incidencia de hipertensión perioperatoria.

Introduction: Perioperative hypertension represents one of the leading alterations detected performing endoscopic cholecystectomy. It is presumed that atenolol has a protective effect able to reduce this morbid condition, likely due to its beta-blocking action. Objective: To assess the efficacy of atenolol on preventing perioperative hypertension performing laparoscopic cholecystectomy in the surgical unit of the Hospital Clínico Quirúrgico "Lucía Íñiguez Landín" of Holguín. Method: An observational, analytical, longitudinal and prospective cohort study was conducted with two study groups at the same time, experimental group and control group, from January to December, 2018. A total of 697 patients (N=697) evaluated in the preoperative consultation were involved in the study, the sample included 183 hypertensive patients (n=183) who underwent endoscopic surgery for gallbladder lithiasis, of whom 95 were randomized to the atenolol treatment group and 88 to the control group. Patients in the treatment group were administered atenolol at 25 mg daily for 15 days before surgery. Leading variables used were systolic, diastolic and mean arterial pressures, and specific indicators were used to evaluate treatment effectiveness. Results: Preoperative arterial pressures decreased significantly with the use of atenolol in the treatment group. Perioperative hypertension was more frequent in the control group. Atenolol is a selective beta 1 receptor blocker, who causes a hypertensive effects in the central level, depressing the bulbar vasomotor center. Conclusions: The results of this investigation show that the use of atenolol in treatment was an effective alternative, thus effectiveness reduce perioperative hypertension rate.
