Abordaje integral del adulto mayor ante diferentes formas de abuso: un acercamiento desde la medicina familiar en Colombia / Comprehensive Approach to the Elderly in the Face of Different Forms of Abuse: Boarding from Family Medicine in Colombia

RESUMEN El envejecimiento poblacional es un tema de gran importancia por su crecimiento rápido y progresivo en los últimos años. Así mismo, con el aumento de la edad crece el grado de dependencia funcional, por consiguiente, mayor probabilidad de maltrato en el adulto mayor; convirtiéndose en un problema social y de salud pública a nivel mundial. El objetivo de este artículo es dar a conocer la importancia del abuso en el adulto mayor, sospecha y reconocimiento oportuno del mismo para realizar un abordaje integral desde la atención primaria. Se realizó una revisión narrativa que incluyó revisiones sistemáticas, revisiones de la literatura, reportes de caso y otros elementos, como noticias locales en Colombia, entre 2015 a 2019. No existe consenso alguno de la definición exacta, sin embargo, la más aceptada es la propuesta por la Organización Mundial de la Salud y la Organización de los Estados Americanos. Se han identificado factores de riesgo individuales, relacionales, socioculturales y comunitarios asociados a la perpetuación de este. Su clasificación está basada en dos grandes grupos: maltrato directo e indirecto. Existen diferentes herramientas de tamización de maltrato en el adulto mayor, dentro de estas la más utilizada es el Elder Abuse Suspicion Index (EASI), y estrategias que ayudan al médico de atención primaria al reconocimiento temprano y abordaje holístico del paciente. Tanto en Colombia como a nivel mundial, el Médico Familiar está en la capacidad de establecer un contacto más cercano con el anciano y su entorno generando un clima de confianza y empatía que permiten al profesional desde la atención primaria la detección temprana y prevención de cualquier tipo de abuso en esta población.

ABSTRACT Population ageing is an important issue due to its rapid and progressive growth in the last years. In addition, with increasing age, the degree of functional dependence increases, and with it, the likelihood of abuse in older adults, becoming a global social and public health problem. The aim of this article is to show the importance of abuse in older adults, and of early suspition and discovery, in order to carry out a comprehensive approach. This narrative review included systematic reviews, literature reviews, case reports, and other elements such as local news in Colombia, from 2015 to 2019. There is no consensus on the exact definition, however, the most accepted is the proposal of the World Health Organization and the Organization of American States. Several risk factors associated with its perpetuation have been identified, including relational, individual, sociocultural, and community factors. The abuse of older adults is classified into five groups: physical, emotional or psychological, economic or financial, sexual abuse, and neglect, the latter also includes abandonment. There are different screening tools for older adult abuse, among which the most used is the Elder Abuse Suspicion Index (EASI), and strategies that help the primary care physician to early recognition and carry out a holistic approach. Both in Colombia and worldwide, the Family Physician can establish closer contact with the older adults and their environment, generating a climate of trust and empathy that helps the primary care professional to early detection and prevention of any kind of abuse in this population.

Linfadenectomía inguinal por video endoscopia (VEIL) para el manejo de cáncer vulvar en el Instituto Nacional de Cancerología (Bogotá, Colombia) / Video endoscopic inguinal lymphadenectomy (VEIL) for the management of vulvar cancer at the Instituto Nacional de Cancerología (Bogotá, Colombia)

Resumen El cáncer de vulva representa el 2% al 5% de todos los cánceres ginecológicos a nivel mundial, dentro de los cuales, el más frecuente es el carcinoma escamocelular seguido por el melanoma. La cirugía es la piedra angular en el tratamiento de la neoplasia vulvar, y la evaluación del estado ganglionar es un poderoso predictor de supervivencia. La linfadenectomía inguinofemoral hace parte de las estrategias de tratamiento. La aproximación quirúrgica mínimamente invasiva por video endoscopia (VEIL) es una alternativa a la vía abierta que disminuye la morbilidad postoperatoria como dehiscencia de la herida quirúrgica, linfocele, linfedema, infección y deterioro psicosexual. A continuación, se describe la técnica quirúrgica VEIL como abordaje novedoso en Colombia para el manejo de la neoplasia vulvar.

Abstract Vulvar cancer represents 2% to 5% of all gynecological cancers worldwide, of which the most common is squamous cell carcinoma followed by melanoma. Surgery is the cornerstone in the treatment of vulvar neoplasia, and evaluation of lymph node status is a powerful predictor of survival. Inguinofemoral lymphadenectomy is part of the treatment strategies. The minimally invasive surgical approach by video endoscopy (VEIL) is an alternative to the open approach that reduces postoperative morbidity such as dehiscence of the surgical wound, lymphocele, lymphedema, infection, and psychosexual deterioration. The following describes the surgical technique of VEIL, as a novel approach in Colombia for the management of this cancer.

Papel de la linfadenectomía paraaórtica inframesentérica durante la histerectomía radical en pacientes con cáncer cervical estadio IB1 en el Instituto Nacional de Cancerología Bogotá, Colombia / Role of inframesenteric para-aortic lymphadenectomy during radical hysterectomy in patients with IB1 cervical cancer in Instituto Nacional de Cancerología Bogota, Colombia

INTRODUCCIÓN: El cáncer cervical es una patología común en países en vías de desarrollo. La histerectomía radical es el estándar de manejo en estadios tempranos sin deseo de fertilidad. La linfadenectomía paraaórtica como parte del tratamiento quirúrgico es controversial. El objetivo de este estudio es determinar la frecuencia de compromiso ganglionar paraaórtico en una serie retrospectiva de pacientes con carcinoma cervical estadio IB1 (clasificación FIGO 2009) llevadas a histerectomía radical mas linfadenectomía pélvica y paraaórtica en el Instituto Nacional de Cancerología durante el periodo de enero 1 de 2009 a marzo 31 de 2017. MÉTODOS: Estudio descriptivo, retrospectivo. Se describieron variables clínicas, operatorias e histopatológicas. Se determinó la frecuencia de compromiso ganglionar a nivel paraaórtico o pélvico, y concurrente. Se realizó análisis univariado en el software estadístico R Project versión 3.6.0. RESULTADOS: Se incluyeron 88 casos. El promedio de edad fue 44,24 ± 9,99 años. La mediana del número de ganglios pélvicos y paraaórticos resecados fue de 23 (6-68) y 4 (1-25), respectivamente. En el 12,5% de las pacientes se observó compromiso tumoral ganglionar pélvico. No se detectó compromiso metastásico de ganglios paraórticos en ningún caso. Dos pacientes presentaron recaída ganglionar paraaórtica durante el seguimiento, recibiendo tratamiento con quimioterapia y quimiorradioterapia de campo extendido, respectivamente. CONCLUSIÓN: En este estudio no se detectó compromiso paraaórtico en pacientes con cáncer cervical IB1 sometidas a histerectomía radical. Este resultado se debe considerar al ofrecer linfadenectomía paraaórtica en pacientes con ganglios pélvicos aparentemente normales en el acto operatorio y/o en los estudios de imágenes prequirúrgicas.

INTRODUCTION: Cervical cancer is a common pathology in developing countries. Radical hysterectomy is the standard of management in early stages without desire for fertility. Paraaortic lymphadenectomy as part of surgical treatment is controversial. The objective of this study is to determine the frequency of paraaortic lymph node involvement in a retrospective series of patients with stage IB1 cervical carcinoma (FIGO 2009 classification) underwent to radical hysterectomy plus pelvic and paraaortic lymphadenectomy at the Instituto Nacional de Cancerologia during the period of January 1 2009 to March 31 2017. METHODS: Descriptive, retrospective study. Clinical, operative, and histopathological variables were described. The frequency of paraaortic, pelvic, concurrent lymph node involvement and adjuvant treatment was determined. A univariate analysis of the variables was performed in the R project statistical software version 3.6.0. RESULTS: 88 cases were included. The mean age was 44,24 ± 9,99 years. The median number of resected pelvic and para-aortic nodes was 23 (6-68) and 4 (1-25), respectively. In 12,5 % of the patients, involvement of the pelvic lymph nodes was present. No patient had paraaortic lymph node involvement. Two patients presented para-aortic lymph node relapse during follow-up, receiving treatment with chemotherapy and extended field chemoradiotherapy, respectively. CONCLUSION: In this study, the frequency of paraaortic involvement in patients with cervical cancer IB1 was 0%. This result should be considered when offering paraaortic lymphadenectomy in patients with apparently normal pelvic nodes in presurgical imaging studies and during the procedure.

Disminución de complicaciones neurológicas peri-operatorias en pacientes con endarterectomía carotídea bajo anestesia regional

INTRODUCCIÓN: La endarterectomía carotídea es el estándar de oro para disminuir la incidencia de evento cerebral isquémico en pacientes con enfermedad ateroesclerótica carotídea sintomática o severa. Sin embargo, durante el procedimiento se requiere la interrupción de flujo sanguíneo cerebral por la carótida interna, lo que puede conllevar una inadecuada perfusión cerebral y un evento cerebrovascular perioperatorio. OBJETIVO: Determinar la incidencia de eventos cerebrovasculares perioperatorios, mortalidad y complicaciones, así como la estancia hospitalaria, en pacientes llevados a endarterectomía carotídea en el Hospital de San José, en Bogotá, Colombia. Además, se comparará el beneficio del uso de anestesia local, en comparación con anestesia general, en los pacientes llevados a este procedimiento quirúrgico, para disminuir el riesgo de eventos cerebrovasculares. METODOLOGÍA: Estudio de cohorte retrospectiva de pacientes llevados a endarterectomía carotídea entre noviembre del 2006 y noviembre del 2017. RESULTADOS: 32 pacientes fueron llevados a endarterectomía carotídea, de los cuales 12 (37,5 %) fueron bajo anestesia general y 20 (62,5 %) bajo anestesia regional. La incidencia de ECV global fue del 15,6 %. Requirieron shunt 12 pacientes (37,5 %), con una incidencia de infarto cerebral en pacientes en los que se usó shunt del 33,3 %, en comparación con el 5 % en los que no se usó. La mortalidad global y las complicaciones fueron de 3,1 % y la mediana de días de estancia hospitalaria en los pacientes de anestesia general fue de cuatro días (RIQ = 3,5-8,5), en contraste con los 2,5 días (RIQ = 2-7,5) en pacientes de anestesia regional. CONCLUSIONES: Según la experiencia obtenida en el Hospital de San José, existe una menor incidencia de ECV perioperatorio, menor tasa de mortalidad, una estancia hospitalaria y en UCI en los pacientes llevados a endarterectomía carotídea bajo anestesia regional.

SUMMARY INTRODUCTION: Carotid endarterectomy is the gold standard for reducing the incidence of ischemic stroke in patients with symptomatic or severe carotid atherosclerosis. However, the procedure requires the interruption of cerebral blood flow by the internal carotid, this can result in inadequate cerebral perfusion and a perioperative cerebrovascular event. OBJECTIVE: To determine the incidence of peri-operative cerebrovascular events, mortality and complications, as well as hospital stay, in patients undergoing carotid endarterectomy at the Hospital de San José de Bogotá. We also compared the benefit of using local anesthesia vs general anesthesia in patients taken to this surgical procedure to reduce the risk of cerebrovascular events METHODOLOGY: Study of a retrospective cohort of patients undergoing carotid endarterectomy between November 2006 and November 2017. RESULTS: 32 patients were taken to a carotid endarterectomy of which 12 (37.5 %) were under general anesthesia and 20 (62.5 %) were under regional anesthesia, the incidence of global CVD was 15.6 %. Twelve patients (37.5 %) required a shunt with an incidence of cerebral stroke in patients in whom a shunt of 33.3 % was used. 5 % in those that were not used. Overall mortality and complications were 3.1 % and median hospital stay in patients under general anesthesia for 4 days (RIQ: 3.5-8.5) versus regional anesthesia 2.5 days (RIQ: 2-7.5). CONCLUSIONS: According to the experience in the hospital of San José de Bogotá, there is a lower incidence of cerebrovascular events, in the perioperative period, a lower mortality rate, a hospital stay and in the lower intensive care unit in patients undergoing carotid endarterectomy under regional anesthesia.

Validation of a predictive model for successful vaginal birth after cesarean section / Validación de modelos predictivos para parto vaginal exitoso después de cesárea

Abstract Introduction: A strategy for reducing the number of cesarean sections is to allow vaginal delivery after cesarean section. Objective: To validate two predictive models, Metz and Grobman, for successful vaginal delivery after a cesarean section. Methods: Retrospective cohort study involving women with previous history of a previous segmental cesarean section, single pregnancy ≥37 weeks and cephalic presentation. The proportion of vaginal delivery in all pregnant women was determined, and it was compared with those (women) with successful delivery after cesarean section. Then, there were elaborated the models, and their predictive capacity was determined by curve-receiver-operator. Results: The proportion of successful delivery in pregnant women with a previous cesarean section and indication of vaginal delivery was 85.64%. The observed proportion of birth for each decile predicted in the Grobman model was less than 15%, except for the 91-100% decile, where it was 64.09%; the area under the curve was 0.95. For the Metz model, the actual successful delivery rate was lower than predicted in scores between 4 and 14, and within expected for a score between 15 and 23; the area under the curve was 0.94. Conclusions: The vaginal delivery rate after cesarean was lower than expected according to the predictive models of Grobman and Metz. The implementation of these models in a prospective way can lead to a higher rate of successful birth.

Resumen Introducción: Una estrategia de reducción del número de cesáreas es permitir el parto vaginal después de cesárea. Objetivo: Validar dos modelos predictivos, Metz y Grobman, para el parto vaginal exitoso después de una cesárea. Métodos: Estudio de cohorte retrospectivo con mujeres con antecedente de una cesárea segmentaria previa, embarazo único ≥37 semanas y presentación cefálica . Se determinó la proporción de parto vaginal en todas las gestantes y se comparó con aquellas con parto exitoso después de cesárea, se elaboró los modelos y se determinó la capacidad predictiva de ellos mediante curva-receptor-operador. Resultados: La proporción de parto exitoso en gestantes con cesárea previa e indicación de parto vaginal fue 85.64%. La proporción de parto observado para cada decil predicho en el modelo de Grobman fue inferior al 15%, excepto para el decil 91-100%, en el que fue 64.09%, el área bajo la curva fue 0.95. Para el modelo de Metz, la proporción de parto exitoso real fue menor a lo predicho en puntajes entre 4-14 y dentro de lo esperado para puntaje entre 15-23, con un área bajo la curva de 0.94. Conclusiones: La tasa de parto vaginal después de cesárea fue menor a lo esperado de acuerdo a los modelos predictivos de Grobman y Metz. La implementación de estos modelos en forma prospectiva puede llevar una mayor tasa de parto exitoso.

Suicidio en poblaciones lesbiana, gay, bisexual y trans: revisión sistemática de una década de investigación (2004-2014) / Suicide in lesbian, gay, bisexual and trans populations: systematic review of a decade of research (2004-2014)

Lesbian, gay, bisexual and trans (LGBT) populations have a high prevalence of suicide behaviors. Aim: To review the literature on suicide among LGBT populations. Material and Methods: A systematic review of the scientific literature published between 2004 and 2014 on suicidality among LGBT people was conducted. Forty-five articles were selected for a thematic analysis. Results: The research on suicide among LGBT people has increased during the last decade. The vast majority of studies have been conducted in the U.S. and other English speaking countries. At the same time, in a great part, these studies have been published in journals specializing in mental health and public health of sexual minorities. In general, they provide a significant foundation on protective and risk factors for suicide as well as their epidemiology. Conclusions: The focus of research on suicide among LGBT populations is mainly exploratory. More attention on these at-risk groups is required from the suicide research community in order to provide useful evidence for prevention and development of focalized and effective interventions.

Alterações hematológicas em cadelas portadoras de tumores de mama

In this study we describe the occurrence of hematological disorders in bitches with mammary neoplasm and analyze the possibility that alterations present can be used as a diagnostic parameter and prognosis. Two hundred and forty-six dogs with mammary neoplasms (123 with malignant and 123 with benign mammary tumor) and the same number of female dogs without mammary tumors were investigated for observation of hematologic abnormalities. The full blood test and measurement of proteins was carried out before any treatment for breast tumor. The diagnosis of mammary neoplasm was done by histopathology. Few animals with benign tumors had hematological disorders, but in malignant neoplasm the prevalence was 55%, and thrombocytosis, hyperproteinemia (hypergammaglobulinemia) and leucopenia (neutropenia) were the most prevalent abnormalities. Anemia and erythrocytosis had equilibrated occurrence (22 and 21%, respectively). Leukocytosis and thrombocytopenia were less hematologic changes observed. We concluded that because of the high prevalence of thrombocytosis, leukopenia and hyperproteinemia (hypergammaglobulinemia) in bitches bearing mammary tumors, the hematological abnormalities may be signaling of malignant neoplasm.

Neste estudo descrevemos a ocorrência de distúrbios hematológicos em cadelas com neoplasia mamária e sua possível relação com o diagnóstico e o prognóstico. Duzentos e quarenta e seis cadelas com neoplasias mamárias (123 com maligno e 123 com tumor mamário benigno) e o mesmo número de cadelas sem tumores mamários foram investigadas para a observação de anormalidades hematológicas. O exame de sangue completo e mensuração de proteínas foram realizados antes de qualquer tratamento para o tumor de mama. O diagnóstico de neoplasia mamária foi feito por exame histopatológico. Poucos animais com tumores benignos tinham distúrbios hematológicos, mas em neoplasia maligna a prevalência foi de 55%, sendo trombocitose, hiperproteinemia (hipergamaglobulinemia) e leucopenia (neutropenia) as anormalidades mais prevalentes. Anemia e eritrocitose tiveram ocorrência equitativa (22 e 21%, respectivamente). Leucocitose e trombocitopenia foram alterações hematológicas menos observadas. Concluiu-se que, devido à alta prevalência de trombocitose, leucopenia e hiperproteinemia (hipergamaglonulinemia) em cadelas com tumores mamários malignos, tais alterações hematológicas podem ser sinalização para o diagnóstico das malignidades e seu prognóstico.

Effect of strontium ranelate on bone remodeling

Osteoporosis is a disease in which the microarchitecture of bone tissue deteriorates, with consequent loss of bone mass. Strontium ranelate (SrR) is currently used for treatment of the condition. SrR may have a dual effect: anabolic (stimulating pre-osteoblast replication) and anti-catabolic (reducing osteoclastic activity). However, its mechanism of action has not yet been completely elucidated. The aim of this study is to evaluate the effect of SrR on bone remodeling in healthy Wistar rats. Two-month old female Wistar rats were administered SrR (2 g/L) in drinking water for 30 weeks. Oriented histological sections were prepared from lower jaw and tibia and stained with H&E, and the following histomorphometric parameters were evaluated: a) in interradicular bone: bone volume, and percentages of bone-formation, quiescent and bone-resorption surfaces; and b) in tibia: bone volume, total thickness of growth cartilage, thickness of hypertrophic cartilage zone and number of megakaryocytes. No significant difference was found in the parameters between the control animals and those treated with SrR. The results would therefore show that SrR does not alter the bone parameters studied in this experimental design.

La osteoporosis es una enfermedad caracterizada por el deterioro de la microarquitectura del tejido oseo y la consecuente perdida de masa osea. El ranelato de estroncio (RSr) es actualmente utilizado para su tratamiento ya que poseeria un efecto dual: anabolico (estimulando la replicacion de preosteoblastos) y anticatabolico (disminuyendo la actividad osteoclastica). Sin embargo, su mecanismo de accion aun no ha sido completamente dilucidado. El objetivo del presente trabajo es evaluar el efecto del RSr sobre la remodelacion osea en ratas Wistar sanas. Se utilizaron ratas Wistar hembras de dos meses de edad a las cuales se les administro RSr (2 gr/L) en el agua de bebida durante 30 semanas. Se realizaron cortes histologicos orientados de maxilar inferior y tibia coloreados con H&E y se evaluaron los siguientes parametros histomorfometricos: a) En hueso interradicular: volumen oseo, porcentaje de superficies en formacion, reposo y reabsorcion osea. b) En tibia: volumen oseo, espesor total del cartilago de crecimiento, espesor de la zona de cartilago hipertrofiado y numero de megacariocitos. No se observaron diferencias significativas en los parametros evaluados entre los animales control y los tratados con RSr. Por lo tanto, los resultados obtenidos indicarian que el RSr no altera los parametros oseos estudiados en el presente diseño experimental.
