Abriendo puertas para la vida: Programa de prevención de conductas suicidas a través de docentes Gatekeepers / Opening doors to life: A suicidal behavior prevention program involving Gatekeeper teachers / Abrindo portas para a vida: Programa de prevenção ao comportamento suicida por meio de professores Gatekeepers

Introducción: El suicidio es la tercera causa de muerte de jóvenes entre 15 y 19 años. Ante esto, los ambientes escolares pueden favorecer el fomento de la salud mental de los adolescentes, permitir la identificación temprana de factores de riesgo y aportar en la prevención de conductas suicidas. Una de las estrategias de prevención es el entrenamiento de "gatekeepers". Objetivo: Determinar el efecto del programa "Abriendo Puertas para la Vida" sobre conocimientos, actitudes y prácticas en prevención de conductas suicidas en un grupo de profesores de secundaria de una institución educativa de San Juan de Pasto, Colombia. Materiales y métodos: Estudio preexperimental, con un grupo de intervención y medidas pre y pos-seguimiento. Participaron nueve docentes voluntarios durante dos jornadas de formación. Resultados: Se identificaron cambios positivos en conocimientos, actitudes y prácticas de los participantes entre pretest y postest, en la mayoría de las subdimensiones evaluadas; sin embargo, tres años después, estos cambios se mantuvieron tan solo en conocimientos sobre las conductas suicidas y en actitudes hacia la prevención. Conclusión: El programa "Abriendo Puertas para la Vida" evidenció efectividad y pertinencia, sin embargo, el mantenimiento de sus efectos requiere de acciones de seguimiento y acompañamiento a los docentes formados.

Introduction: Suicide is the third cause of death in young people aged between 15 to 19 years. Thus, school environments can promote mental health of adolescents through early identification of risk factors and prevention of suicidal behaviors. One prevention strategy is the training of "gatekeepers". Objective: To determine the impact of the "Opening Doors to Life" program on the knowledge, attitudes, and practices regarding prevention of suicidal behavior in a set of high school teachers from an educational institution in San Juan de Pasto, Colombia. Materials and methods: A pre-experimental study with an intervention group and pre- and post-follow-up measurements. Nine volunteer teachers participated during two training sessions. Results: Positive changes regarding knowledge, attitudes, and practices of the participants during pretest and posttest were observed for the majority of evaluated sub-dimensions. However, after three years, the positive measures prevailed only for knowledge about suicidal behavior and attitudes toward prevention. Conclusion: The "Opening Doors to Life" program showed effectiveness and relevance. However, maintaining its impact requires follow-up actions and support of trained teachers.

Resultados cardiometabólicos de largo plazo tras cirugía bariátrica: control de comorbilidades, pérdida y reganancia de peso a los 5 años de seguimiento / Long-term cardiometabolic results after bariatric surgery: Control of comorbidities, weight loss and regain at 5 years of follow-up

Introducción. La cirugía bariátrica y metabólica (CBM) es efectiva en lograr pérdida de peso a corto plazo. Sin embargo, existe evidencia limitada en desenlaces clínicos y metabólicos a largo plazo. Métodos. Estudio longitudinal retrospectivo con pacientes llevados a baipás gástrico en Y de Roux (BGYR) o gastrectomía en manga (MG) por laparoscopia en Bogotá, D.C., Colombia, entre 2013 y 2021. El cambio de peso, control de comorbilidades y resultados metabólicos se recopilaron al inicio del estudio, 3, 6 y 12 meses después de cirugía, y anualmente hasta el quinto año. Las tasas de control de comorbilidades se evaluaron mediante la prueba Kaplan-Meier. Se utilizó un modelo de riesgos proporcionales de Cox para evaluar el efecto de covariables en la reganancia de peso. Resultados. De 1092 pacientes con CBM (71,4 % MG y 28,6 % BGYR), 67 % eran mujeres, con mediana de edad 48 años e índice de masa corporal de 35,5 Kg/m2. Después de cinco años de seguimiento, la tasa de control en diabetes mellitus fue 65,5 %, en hipertensión 56,6 % y en dislipidemia 43,6 %. La tasa de reganancia de peso fue 28 %, sin diferencias entre MG vs BGYR (p=0,482). El tiempo promedio hasta peso nadir fue 14 meses. La edad al momento de CBM fue el mejor predictor independiente de reganancia (HR=1,02, IC95% 1,01-1,04), pero con efecto clínico modesto. Conclusión. La CBM es segura y muestra beneficios a largo plazo en la pérdida de peso y control de comorbilidades en población colombiana.

Introduction. Bariatric and metabolic surgery (BMS) has shown its efficacy in achieving short-term weight loss. However, there is limited evidence regarding long-term clinical and metabolic outcomes. Methods. Retrospective longitudinal study with patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) interventions in Bogotá, Colombia, between 2013 and 2021. Weight change, comorbidity control, and metabolic outcomes were collected at the onset, 3-, 6-, and 12-month post-surgery, and annually up to the fifth year. Comorbidity control rates were assessed using the Kaplan-Meier test. A Cox proportional hazards model was used to evaluate the effect of covariates on weight regain. Results. Of 1092 patients with BMS (71.4% SG and 28.6% RYGB), 67% were women, with a median age of 48 years, BMI 35.5 kg/m2. After five years of follow-up, the control rate in diabetes mellitus was 65.5%, in hypertension 56.6%, and dyslipidemia 43.6%. The weight regain rate was 28% with no differences between SG vs RYGB (p=0.482). The mean time to nadir weight was 14 months. Age at the time of BMS was the best independent predictor of weight regain (HR=1.02, 95%CI: 1.01-1.04), but with a modest clinical effect. Conclusion. BMS is safe and shows long-term benefits in weight loss and control of comorbidities in Colombian population.

Risk factors for shunt-dependent hydrocephalus after spontaneous subarachnoid hemorrhage.

INTRODUCTION: Subarachnoid haemorrhage (SAH) is one of the most frequent neurosurgical emergencies, most of them due to intracranial aneurysm rupture. Hydrocephalus is a prevalent complication with a high rate of complications. The aims of this study are to identify predictors of shunt-dependent hydrocephalus following aneurysmal SAH and to quantify the complications arising from ventriculoperitoneal shunts. METHODS: This study is about an observational retrospective analytic study of the patients with spontaneous SAH admitted to Miguel Servet Universitary Hospital between 2017 and 2022. Patients' clinical and radiological characteristics, type of treatment, diagnoses and treatment of hydrocephalus, complications of ventriculoperitoneal shunts and mortality are some of the data achieved in this study. A descriptive study of these variables has been done and, subsequently, the most relevant variables have been statistically analysed to identify patients with increasing risk of shunting for hydrocephalus. This study was authorized by the Ethics Committee prior to its elaboration. RESULTS: A total of 359 patients with spontaneous SAH were admitted to Miguel Servet Universitary Hospital between 2017 and 2022, with an intrahospitalary death rate of 25.3%. 66.3% of the total of patients with SAH were due to intracranial aneurysm rupture (n = 238). 45.3% of the patients with aneurysmal SAH required an external ventricular drain (EVD) to treat acute hydrocephalus. 11.7% (n = 28) developed a shunt-dependent hydrocephalus. Statistical significance was found between shunt-dependent hydrocephalus and the following: high score in modified Fisher scale and placement of EVD. The mean interval from EVD to ventriculoperitoneal shunt placement was 26.1 days. The mean rate of reoperation of patients after shunt was 17.7%, mostly due to infection. CONCLUSIONS: The most significant risk factor for shunt-dependent hydrocephalus after aneurysmal SAH was high Fisher grade and previous need of EVD. Shunt infections is the main cause of shunt reoperation. Early shunt placement in selected patients might reduce the rate of infectious complications.

COPD patient profiles in primary care. Referral criteria.

COPD is a disease with a high prevalence that diminishes the quality of life of many patients. Despite this, there are still high rates of under-diagnosis in Spain, partly due to a lack of recognition of the pathology by patients. In this context, the role played by primary care teams becomes fundamental, as they are one of the first lines of entry into the health system. In this paper we explain the different COPD profiles that may be present, and update the tools for diagnosis and treatment, which, together with an attitude of active suspicion of the disease, can help in the correct management of patients, whether they are undiagnosed or have subsequent complications.

Why do patients with urinary diversions have an increased risk of bone fracture? A systematic review on risk factors for osteoporosis and bone mineral density loss in this group of patients.

INTRODUCTION: Patients undergoing radical cystectomy with urinary diversions (UD) are at increased risk of bone fractures compared to the general population. Although a loss of bone mineral density (BMD) has been described in patients with UD, we still do not know with certainty why these patients follow this tendency. OBJECTIVE: We performed a systematic review of the available literature to analyze the prevalence of osteoporosis and bone alterations in patients with ileal UD and the possible associated risk factors. EVIDENCE ACQUISITION: We systematically searched PubMed® and Cochrane Library for original articles published before December 2022 according to PRISMA guidelines. EVIDENCE SYNTHESIS: A total of 394 publications were identified. We selected 12 studies that met the inclusion criteria with 496 patients included. Six of the twelve studies showed decreased BMD values. Prevalence of osteoporosis was specified in three articles, with values ranging ​​from 0% to 36%. Risk factors such as age, sex, body mass index, metabolic acidosis and renal function appear to have an impact on bone tissue reduction, while type of UD, follow-up, 25-hydroxyvitamin D and parathormone had less evidence or contradictory data. The heterogeneity of the studies analyzed could led to interpretation bias. CONCLUSIONS: UD are associated with multiple risk factors for osteoporosis and bone fractures. Identifying patients at highest risk and establishing diagnostic protocols in routine clinical practice are essential to reduce the risk of fractures and the resulting complications.

Usefulness of third ventricle volumetry in patients with normal pressure hydrocephalus.

OBJECTIVE: To use third ventricle morphometric variables as a tool for the selection of patients with idiopathic normal pressure hydrocephalus (iNPH) who are candidates for ventriculoperitoneal shunts (VPS). MATERIAL AND METHODS: Retrospective study enrolling patients with iNPH. Katzman infusion test was performed and a Rout > 12 mmHg/mL/min was considered a positive result. The transverse diameter and the volume of the third ventricle were measured in the preoperative MRI. Postoperative improvement was assessed with the NPH score. The results were analysed with SPSS software. RESULTS: 52 patients with a mean age of 76 years were analysed. There was no difference in the diameter of the third ventricle among patients with a positive result and those with a negative result in the infusion test (12.28 vs 11.68 mm; p = 0.14). Neither were difference detected in the ventricle volume of both groups (3.6 vs 3.5cc; p = 0.66). Those patients who improved after VPS had a smaller third ventricle compared to those who did not respond after surgery (11.85 mm vs. 12.96 mm; p = 0.009). Diameter and volume of third ventricle present a significant strong correlation (Pearson correlation coefficient = 0.72; p < 0.0001). CONCLUSION: Morphometric variables of third ventricle may be useful in predicting a good response to VPS in patients with idiopathic normal pressure hydrocephalus.

[Consensus on criteria and minimum data set for the referral of candidate patients for home enteral nutrition teleconsultation: TELENUT project]. / Consenso sobre criterios y conjunto mínimo de datos para la derivación de pacientes candidatos a teleconsulta de nutrición enteral domiciliaria: proyecto TELENUT.

Introduction: Introduction: teleconsultation is a useful healthcare tool in the multidisciplinary management of patients with indications of home enteral nutrition (HEN). The use of different teleconsultation platforms, as it happens in the Andalusian Health System (SAS), results in heterogeneous referral processes between Primary Care and hospital services in the same region. Objectives: to establish a consensus on patient profiles and the minimum data set necessary to guarantee an adequate referral to NED teleconsultation regardless of the existing platform. These agreed aspects in Andalusia can serve as a reference in other regions. Methods: three consecutive steps were followed: a) non-systematic review of the indexed literature on teleconsultation in clinical nutrition in Spain; b) survey to know the implementation and unmet needs of teleconsultation platforms in Andalusian public hospitals; and c) working meetings and consensus of 14 health professionals of Primary Care (n = 4) and endocrinology and hospital clinical nutrition (n = 10). Results: three referral forms were agreed in which three patient profiles were defined, with the corresponding minimum set of data necessary to request NED teleconsultation. The Primary Care team should provide this set of data to the clinical nutrition specialist via a teleconsultation platform, implemented in the SAS. Conclusions: three agreed forms between healthcare professionals involved in the referral process serve to standardize the request for teleconsultation of NED between healthcare teams based on patient profiles.

Introducción: Introducción: la teleconsulta es una herramienta asistencial útil en el manejo multidisciplinar de pacientes con indicación de nutrición enteral domiciliaria (NED). El empleo de diferentes herramientas de teleconsulta de NED, como ocurre en el Sistema Andaluz de Salud (SAS), conlleva heterogeneidad en los procesos de derivación entre los servicios de Atención Primaria (AP) y hospitalaria en una misma región. Objetivos: consensuar perfiles de pacientes y conjunto de datos mínimos necesarios para garantizar una derivación adecuada a la teleconsulta de NED, independientemente de la herramienta existente. Estos aspectos consensuados en Andalucía pueden servir de referencia en otras regiones. Métodos: se siguieron tres pasos consecutivos: a) revisión no sistemática de la literatura indexada sobre la teleconsulta en nutrición clínica en España; b) encuesta para conocer la implementación y las necesidades no satisfechas de las herramientas de teleconsulta en los hospitales públicos andaluces; y c) reuniones de trabajo y consenso de 14 profesionales sanitarios de AP (n = 4) y endocrinología y nutrición clínica hospitalaria (n = 10). Resultados: se consensuaron tres formularios de derivación en los que se definieron tres perfiles de pacientes, con el correspondiente conjunto mínimo de datos necesario para solicitar la teleconsulta de NED. El equipo de AP debe proporcionar este conjunto mínimo de datos al especialista en nutrición clínica a través de una herramienta de teleconsulta, implementada en el SAS. Conclusiones: tres formularios consensuados entre profesionales sanitarios involucrados en el proceso de derivación sirven para estandarizar la solicitud de teleconsulta de NED entre equipos asistenciales en función de perfiles de pacientes.

TIPS en pacientes cirróticos con trombosis venosa portal: una revisión de la literatura / TIPS in cirrhotic patients with portal vein thrombosis: A review of the literature

En los últimos años, la trombosis de la vena porta entre los pacientes cirróticos se ha comportado como una entidad reconocida y cada vez más estudiada, no solo por su creciente incidencia, sino por la asociación con gravedad y mal pronóstico en cirrosis. Asimismo, se hacen objeto de estudio las terapias disponibles para el manejo tanto médico como quirúrgico de estos pacientes, lo que ha dado un papel importante a la derivación portosistémica transyugular intrahepática (TIPS). El uso de TIPS en esta población se posiciona como una alternativa de manejo aceptable, no solo por brindar mejoría en las complicaciones derivadas de la hipertensión portal, sino también por sus resultados prometedores en diferentes estudios sobre el flujo y la recanalización portal, y por su perfil de seguridad. Sin embargo, la eficacia, los efectos adversos a largo plazo y el pronóstico de dicha intervención en la compleja fisiopatología de la cirrosis deben continuar en estudio. El objetivo de este artículo es revisar los avances del uso de TIPS en el manejo de pacientes con cirrosis hepática y trombosis portal.

In recent years, portal vein thrombosis among cirrhotic patients has been a well-recognized and continuously studied entity, not only because of its increasing incidence but also because of its association with severity and poor prognosis in cirrhosis. Likewise, therapies available for both medical and surgical management in these patients are being studied, which has given an important role to the transjugular intrahepatic portosystemic shunt (TIPS). The use of TIPS in this population is positioned as an acceptable management alternative, not only because it provides improvement in complications derived from portal hypertension, but also because of its promising results in different studies on portal flow and recanalization upgrade, and for its safety. However, the efficacy, long-term adverse effects, and prognosis of this intervention in the complex pathophysiology of cirrhosis must continue to be studied. The objective of this article is to review the advances in the use of TIPS in the management of patients with liver cirrhosis and portal vein thrombosis.

Short-term outcomes after selective shunt during carotid endarterectomy: a propensity score matching analysis.

INTRODUCTION AND OBJECTIVES: Carotid cross-clamping during carotid endarterectomy might lead to intraoperative neurologic deficits, increasing stroke/death risk. If deficits are detected, carotid shunting has been recommended to reduce the risk of stroke. However, shunting may sustain a specific chance of embolic events and subsequently incurring harm. Current evidence is still questionable regarding its clear benefit. The aim is to determine whether a policy of selective shunt impacts the complication rate following an endarterectomy. MATERIAL AND METHODS: From January 2013 to May 2021, all patients undergoing carotid endarterectomy under regional anesthesia with intraoperative neurologic alteration were retrieved. Patients submitted to selective shunt were compared to a non-shunt group. A 1:1 propensity score matching (PSM) was performed. Differences between the groups and clinical outcomes were calculated, resorting to univariate analysis. RESULTS: Ninety-eight patients were selected, from which 23 were operated on using a shunt. After PSM, 22 non-shunt patients were compared to 22 matched shunted patients. Concerning demographics and comorbidities, both groups were comparable to pre and post-PSM, except for chronic heart failure, which was more prevalent in shunted patients (26.1%, P=0.036) in pre-PSM analysis. Regarding 30-day stroke and score Clavien-Dindo ≥2, no significant association was found (P=0.730, P=0.635 and P=0.942, P=0.472, correspondingly, for pre and post-PSM). CONCLUSIONS: In this cohort, resorting to shunting did not demonstrate an advantage regarding 30-day stroke or a Clavien-Dindo ≥ 2 rates. Nevertheless, additional more extensive studies are mandatory to achieve precise results concerning the accurate utility of carotid shunting in this subset of patients under regional anesthesia.

[Comprehensive approach to vertigo: Diagnostic algorithm, causes, treatments, and referral criteria from the perspective of primary care. SEMERGEN consensus document]. / Abordaje integral del vértigo: algoritmo diagnóstico, causas, tratamientos y criterios de derivación desde la perspectiva de atención primaria. Documento de consenso SEMERGEN.

Vertigo is a common symptom that can have various causes and may require a comprehensive approach for its diagnosis and treatment from primary care. A diagnostic algorithm based on the classification proposed by the Otoneurology Commission of the SEORL-PCF is suggested, which facilitates the classification of the different types of vertigo and provides referral criteria for patients from primary care to other specialties. A review of the available treatments based on the underlying cause is conducted for appropriate therapeutic management. This document is expected to become a valuable tool for professionals treating patients with vertigo. The document is based on scientific evidence and on the experience of experts in the field from various medical specialties; and seeks to improve the understanding and clinical approach to acute vertigo from primary care.

What do we see when we do not see the bladder? Review of the main urinary diversion techniques and their complications.

OBJECTIVE: To review the different types of urinary diversion surgeries (UDS) in order to recognize the expected findings in a postoperative study, using different imaging techniques. To recognize the main postoperative complications, both early and late. CONCLUSION: UDS are surgical procedures whose purpose is to redirect urine flow after cystectomy, generally in an oncologic context. The imaging evaluation of urological surgeries is often a radiological challenge, with CT being the most commonly used image modality. Therefore, it is essential to know the main surgical techniques, the expected postoperative findings and the optimization of imaging techniques for early diagnosis and correct evaluation of postoperative complications.

Introduction. Bariatric surgery is a valid strategy of treatment for severe obesity. The aim of this study is to evaluate weight loss and resolution of comorbidities comparing two procedures, Roux-en-Y gastric bypass and sleeve gastrectomy. Methods. Descriptive study of analytical type that included patients with obesity grades II and III. Demographic and perioperative variables were analyzed. The weight reduction was evaluated among others with the percentage of excess of body weight loss. Comorbidities associated with obesity were also analyzed. A univariate descriptive analysis was performed, using medians, interquartile ranges, frequencies, and proportions. The Mann-Whitney U and Chi squared tests were used for analysis of groups. A value of p <0.05 was considered statistically significant. Median follow-up was 28 months. Results. A total of 201 patients were included in the analysis. The median percentage of excess of body weight loss at 18 months was 77.4% for Roux-en-Y gastric bypass group vs 69.5% for sleeve gastrectomy group (p=0.14). The majority of patients presented resolution or improvement of hypertension (76%), diabetes mellitus (80%), dyslipidemia (73%), sleep apnea (79%), and arthropathy (94%), without significant differences according to the surgical technique used. Major complication rate was 1.9%. There was not mortality. The median follow-up was 28 months. Conclusion. Roux-en-Y gastric bypass and sleeve gastrectomy are both very safe and effective procedures for excess weight reduction and resolution of comorbidities associated with obesity

Colangiopancreatografía endoscópica asistida por laparoscopia para el tratamiento de coledocolitiasis en pacientes con Y de Roux / Laparoscopic-assisted endoscopic cholangiopancreatography for the treatment of choledocholithiasis in patients with Roux-en-Y

Introducción. Los pacientes con antecedente de baipás gástrico que presentan coledocolitiasis no pueden ser tratados con la técnica convencional de colangiopancreatografía retrógrada endoscópica. En estos casos, la vía transgástrica abierta o asistida por laparoscopia, se convierte en una excelente alternativa a la exploración abierta de la vía biliar. Métodos. Estudio retrospectivo que incluyó pacientes adultos con coledocolitiasis y antecedente de gastrectomía subtotal o baipás gástrico con Y de Roux, llevados a colangiopancreatografía endoscópica transgástrica laparo-asistida, entre enero de 2019 y diciembre de 2021, en la Clínica CES de Medellín, Colombia. Resultados. Se encontraron siete pacientes, todos con antecedente de baipás gástrico para el manejo de la obesidad. La tasa de identificación y canulación de la vía biliar y extracción de cálculos fue del 100 % mediante el abordaje transgástrico laparo-asistido. Conclusión. De acuerdo con varias revisiones sistemáticas, esta técnica es relativamente fácil de implementar y segura, presentando una tasa de complicaciones inferior a 5 %. Se propone una variante de esta técnica

Introduction. Patients with a history of gastric bypass who present with choledocholithiasis cannot be treated with the conventional technique of endoscopic retrograde cholangiopancreatography. In these cases, the open or laparoscopic-assisted transgastric approach becomes an excellent alternative to open bile duct gastric exploration. Methods. A retrospective review of patients with choledocholithiasis and a history of subtotal gastrectomy or gastric bypass with Roux-en-Y, who underwent laparo-assisted transgastric endoscopic cholangiopancreatography, was conducted between January 2019 and December 2021 at Clínica CES de Medellín, Colombia. Results. Seven patients were found, all with a history of gastric bypass secondary to obesity. The rate of bile duct identification and cannulation, and stone removal was 100% using the laparo-assisted transgastric approach. Conclusion. According to several systematic reviews, this technique is relatively easy to implement and safe, presenting a rate of complications less than 5%. A variant to this technique is proposed

Prevalence of metabolic acidosis in ileal diversions more than one year after radical cystectomy and associated secondary metabolic effects.

INTRODUCTION AND OBJECTIVE: Metabolic acidosis (MA) is a well-known complication in patients with ileal urinary diversions. It is common in the early postoperative stages and decreases over time. Our objective is to investigate the prevalence of MA after more than one year of follow-up, identify the associated risk factors, and analyze its secondary metabolic consequences. MATERIALS AND METHODS: We conducted an observational study between January 2018 and September 2022 following the STROBE guidelines. MA was defined as a serum bicarbonate level ​​<22mEq/L. Finally, we analyzed 133 patients with a mean follow-up of 55.24 ± 42.36 months. RESULTS: MA was observed in 16 (12%) patients. Patients with and without MA were comparable in age, sex, and follow-up time. The group with MA presented a higher rate of anemia (68,75% vs 19,65%, p < 0.001) and renal failure (100% vs 45,29%, p < 0.001), statistically significant higher levels of serum creatinine, chloride, potassium, parathyroid hormone, and phosphorus but lower serum values ​​of hemoglobin, renal glomerular filtration rate, total cholesterol, vitamin D, calcium, and albumin (all p < 0.05). Renal glomerular filtration rate was the only independent risk factor related to the development of MA (OR 0.914; 95% CI 0.878-0.95; p < 0.0001), proving a close correlation with venous bicarbonate values ​​(r = 0.387, p < 0.001). CONCLUSIONS: MA is a little prevalent disorder in ileal urinary diversions more than one year after radical cystectomy is performed but it has secondary consequences on hematologic, renal, protein, lipid, and bone metabolism. We recommend to a close follow-up in patients with renal failure for early diagnosis and treatment.

Self-esteem and quality of life in patients with neurogenic dysfunction and continent urinary diversion and/or procedures for anterograde enemas.

INTRODUCTION AND OBJECTIVE: The importance of evaluating the self-esteem and quality of life of patients with a chronic disease has become increasingly relevant. The study describes self-esteem and quality of life outcomes in patients with neurogenic dysfunction and continent urinary diversions and/or antegrade enema procedures. MATERIALS AND METHODS: Cross-sectional observational study, including patients with neurogenic dysfunction who required a continent urinary diversion and/or an antegrade enema conduit during their treatment. The self-esteem evaluation was done with the Rosenberg scale and the quality of life with the KIDSCREEN-27 questionnaire. VARIABLES MEASURED: socio-demographic, clinical and economic characteristics. Descriptive statistics were applied. RESULTS: The mean age of the 9 patients was 15.6 years, the mean time elapsed from surgery to application of the questionnaires was 60.9 ±â€¯37.1 months. With a perception of improvement in 8 of the 9 patients and a normal or higher self-esteem score in all cases. In the description of physical activity and health, it was found that 7 of the 9 young people presented a perception of good health in general. A considerable reduction in the use of diapers was achieved after the intervention, going from consuming 6.2 ±â€¯1.4 diapers per day to only 1.7 ±â€¯1.3 diapers per day. CONCLUSIONS: Despite the sequelae, comorbidities and procedures, the results of self-esteem and quality of life in patients with neurogenic dysfunction are high.

Frecuencia de referencias ambulatorias injustificadas, en base a diagnósticos no pertinentes, realizadas a un hospital peruano de tercer nivel / Frequency of unjustified ambulatory referrals bases on no pertinent diagnosis sent to a third level Peruvian hospital

Objetivo: Determinar la frecuencia y describir las características de referencias injustificadas, en base a diagnósticos no pertinentes, enviadas al servicio de consulta externa adultos de un hospital de tercer nivel. Material y métodos: Estudio transversal, observacional y descriptivo, realizado en el Hospital Cayetano Heredia (HCH) en el periodo abril a diciembre del 2019. Se utilizaron los datos del aplicativo "REFCON" con una población de 99 891 referencias. Para la variable "justificación de la referencia", se utilizó un listado de diagnósticos que no deberían derivarse a hospitales de la DIRIS Lima Norte. Adicionalmente, se estudiaron las variables de edad, sexo, grupo etario, especialidad de destino, categoría del EESS de origen, distrito de origen, y diagnóstico del grupo de referencias injustificadas. Se utilizó estadística descriptiva. Resultados: La frecuencia de referencias injustificadas fue de 8,4 %. El 34,2 % fue de pacientes adultos; el 65,8 %, de adultos mayores; y el 67 %, de pacientes mujeres Las especialidades con más referencias injustificadas fueron cardiología, geriatría, medicina interna, medicina familiar y neurología. Los diagnósticos injustificados más frecuentes fueron hipertensión esencial, lumbago no especificado y cefalea. Conclusiones: La frecuencia de referencias injustificadas al HCH por diagnósticos no pertinentes fue 8,4 %, tasa similar a otros dos estudios, pese a la emisión de una lista de diagnósticos que no deberían derivarse a hospitales de la DIRIS Lima Norte.

SUMMARY Objective: To determine the frequency and to describe the characteristics of unjustified ambulatory referrals bases on no pertinent diagnosis done at an adult outpatient clinic of a third level Peruvian hospital. Methods: A cross-sectional study was carried-out from April to December 2019 at Hospital Cayetano Heredia. Data were extracted from REFCON with a population of 99 891 referrals. To justify the reference, a list of diagnosis that does not require referral was used. In addition, variables such as age, sex, specialty of destination, category of EESS, district of origin and diagnosis of the unjustified referral. Descriptive statistics was used. Results: the frequency of unjustified referrals was 8.4%; 34.2% comprised the adult population; 65.8% were elder and 67% were female. Specialties with more unjustified referrals were geriatrics, internal medicine, family medicine and neurology. The most common unjustified diagnosis was essential hypertension, nonspecific low back pain and headache. Conclusions: Despite of socializing a list of unjustified referral diagnosis a frequency of 8,4% remain in this category, which is like results from two previous studies.

Shunt portosistémico, una causa poco frecuente de hepatitis colestásica en neonatología. A propósito de un caso / Portosystemic shunt, a rare cause of neonatal cholestatic hepatitis. A case report

El shunt portosistémico congénito es una anomalía vascular venosa que comunica circulación portal y sistémica, por la que se deriva el flujo sanguíneo, salteando el paso hepático. Es una entidad poco frecuente, cuya incidencia varía entre 1/30 000 y 1/50 000 recién nacidos. Puede cursar de forma asintomática o presentarse con complicaciones en la edad pediátrica o, menos frecuente, en la edad neonatal. Ante el diagnóstico, se deberá definir la necesidad de intervención quirúrgica o intravascular para el cierre. Esta decisión depende de las características anatómicas de la malformación, de las manifestaciones clínicas y complicaciones presentes. Se presenta el caso de un paciente de un mes de vida derivado a nuestro centro para estudio de hepatitis colestásica neonatal, con diagnóstico de shunt portosistémico extrahepático. Se realizó cierre intravascular de la lesión con mejoría significativa posterior.

Congenital portosystemic shunt is a venous vascular abnormality that connects portal and systemic circulation, resulting in diversion of the blood flow, bypassing the hepatic passage. It is a rare malformation; its incidence varies from 1:30 000 to 1:50 000 newborns. It may be asymptomatic or present with complications in the pediatric age or, less frequently, in the neonatal age. Upon diagnosis, the need for a surgical or an intravascular intervention for closure should be defined. This decision depends on the malformation anatomical characteristics, clinical manifestations, and complications. We present the case of a 1-month-old patient referred to our center for the study of neonatal cholestatic hepatitis, with a diagnosis of extrahepatic portosystemic shunt. Intravascular closure of the defect was performed with significant subsequent improvement.

Attitudes and beliefs of argentinian medical oncologists regarding palliative care referral / Actitudes y creencias de los médicos oncólogos argentinos sobre la derivación a cuidados paliativos

Abstract Introduction: Local evidence suggests insufficient access to palliative care (PC) for advanced cancer patients. The objective was to investigate the attitudes and beliefs of Argentinian medical oncologists regarding PC referral of their patients. Methods: All medical oncologists listed in the main national Clinical Oncology Associations (N = 831) were invited to participate in a telephone survey. Results: Fifty nine percent (N = 489) completed the survey. Most reported being informed about the scopes of PC (83%) and having accessible PC service/specialists (71%). However, 53% did not work collaboratively, and 55% exceptionally or never referred their patients. Oncologists who usually referred their patients did so mainly due to uncontrolled pain (67%) or absence of curative treatment (48%). Only 19% supported early-referral criteria. Those who exception ally referred their patients argued that PC was not meaningful/beneficial/a priority (78%) or that they preferred to handle the patient's problems by themselves (55%). End-of-life care (33%) and improvement in quality of life (32%) were stated as primary benefits of PC for cancer patients. Addressing psychological aspects was consid ered the least important item (2%). Having an accessible PC service (P = 0.002) and being well informed about PC (P = 0.008) were associated with frequent referral. Having ≤10 years or >30 years from graduation were associated with exceptional or no referral (P = 0.012 and 0.001, respectively). Discussion: Oncologists report awareness of the potential advantages of PC and have accessible PC services, but rarely refer patients. They mainly use late-referral criteria. Younger and older age are negatively associated with referral. More research is needed to improve the referral rate and timing of cancer patients to PC.

Resumen Introducción: La evidencia local sugiere un acceso insuficiente a los cuidados paliativos (CP) para los pacien tes con cáncer avanzado. El objetivo fue investigar las actitudes y creencias de médicos oncólogos argentinos respecto de la derivación de sus pacientes a CP. Métodos: Todos los médicos oncólogos registrados en las principales Asociaciones Nacionales de Oncología Clínica (N = 831) fueron invitados a participar en una encuesta telefónica. Resultados: El 59% (N = 489) completó la encuesta. La mayoría informó estar informado sobre los alcances de CP (83%) y tener especialistas/servicios de CP acce sibles (71%). Sin embargo, el 53% no trabajaba de forma colaborativa y el 55% excepcionalmente o nunca derivaba a sus pacientes. Los oncólogos que habi tualmente derivan a sus pacientes lo hacen principalmente por dolor no controlado (67%) o ausencia de trata miento curativo (48%). Solo el 19% mencionó criterios de derivación temprana. Aquellos que excepcionalmente derivan a sus pacientes argumentaron que los CP no era significativos, beneficiosos o prioritarios (78%) o que preferían manejar los problemas del paciente por sí mismos (55%). La atención al final de la vida (33 %) y la mejora de la calidad de vida (32 %) se señalaron como los principales beneficios de los CP para los pacientes con cáncer. El abordaje de los aspectos psicológicos fue el ítem menos señalado (2%). Tener un servicio de CP accesible (P= 0,002) y estar bien informado sobre CP (P = 0,008) se asociaron con la derivación frecuente. Tener ≤10 años o >30 años desde la graduación se asoció con una derivación excepcional o nula (P = 0,012 y 0,001, respectivamente). Discusión: Los oncólogos refieren conocer las ventajas potenciales de los CP y tienen servicios de CP accesibles, pero rara vez derivan pacientes. Utilizan principalmente criterios de derivación tardía. Las edades más jóvenes y mayores se asocian negativamente con la derivación. Se necesita más investigación para mejorar la tasa y momento de derivación de los pacientes con cáncer a CP.

Sinking bone flap due to overdrainage of a ventriculoperitoneal shunt. A case report and review of the literature.

The widespread use of decompressive craniectomy and subsequent cranioplasty has led to a better understanding of its complications. However, cases of a sunken bone flap have hardly ever been described. We present the eighth case reported up to date and perform a review of the literature of this sporadic complication. A 40-year-old Caucasian male suffered a traumatic brain injury that required a decompressive craniectomy. One month after initial trauma autologous cranioplasty was performed. A ventriculoperitoneal shunt was also placed. Neurological status progressively improved but his therapist noted cognitive status decline 8 months later. Follow-up computed tomography showed a progressive sinking bone flap. The patient underwent bone flap removal and a custom-made calcium phosphate-based implant was inserted, leading to symptoms resolution. Bone resorption has been described as the main cause of sinking bone flap following cranioplasty. This entity may manifest with symptoms of overdrainage in patients with cerebrospinal fluid shunt devices.
