ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) and major bleeding (MB) are common in cancer patients. Reduced-doses of antithrombotics as secondary prophylaxis have limited data. This work aims to describe and to compare treatments and outcomes for cancer-associated VTE. RESEARCH DESIGN AND METHODS: Retrospective study. Adults with cancer-associated VTE were included. After 3-6 months of full-doses of anticoagulants, three strategies were considered: A) lowering the doses; B) maintaining full-doses; C) stopping treatment. The strategy and medication used were shown in a descriptive analysis and the rate of bleeding and VTE-recurrence between those in a comparative analysis. RESULTS: A total of 420 patients were included, 56.2% received DOACs, 43.8% enoxaparin. Strategy was defined in 257 patients: A (50.2%), B (46.3%), and C (3.5%). Forty-one (9.8%) had VTE-recurrence and 15 (3.6%) had MB or clinically relevant non-major bleeding (CRNMB).According to strategy, recurrent-VTE was 8.5% (A), 4.2% (B), and 11.1 (C) (p = 0.22), MB or CRNMB was 0.8% (A), 1.7% (B), and 0% (C) (p = 0.64). CONCLUSIONS: DOACs and strategy A were the most frequently used agent and strategy, respectively. There were no differences between medications or strategies used. The results must be interpreted with caution, and it is a retrospective single-center study, probably with information and selection bias.

ABSTRACT

Resumen Introducción: La posturografía es un método de exploración complementario para valorar el grado de desplazamiento del centro de gravedad (COP); no debe usarse de forma aislada al evaluar equilibrio, pero se acepta para seguimiento de la respuesta a tratamiento. Es de baja disponibilidad, por su alto costo comercial. Como alternativa se documenta la plataforma Wii Balance Board (WBB) de Nintendo para registro posturográfico. Objetivo: Describir valores de normalidad en parámetros posturográficos en población chilena sin patología vestibular, usando un registro simple y accesible. Material y Método: Estudio transversal de valores referenciales en herramienta para evaluación del equilibrio. Se registraron valores posturográficos con versión adaptada del Sensory Organization Test (SOT) a adultos sanos. Mediciones con software WBB Sway Program mediante WBB. Se midieron índices somatosensorial, visual y vestibular, y patrones de control postural en ejes anteroposterior y mediolateral durante SOT-adaptado. Resultados: Se obtuvieron valores de velocidad de desplazamiento del COP, área del COP y desviaciones estándar correspondientes para 4 situaciones del SOT-adaptado de 35 sujetos entre 18-65 años, 21 mujeres, 14 hombres. Discusión: WBB permitió evaluar estos parámetros en población sana, como aproximación a determinar rangos de referencia. Esta herramienta de uso rápido y accesible constituye una alternativa útil para determinar patrones de control postural en sujetos sanos. Presentamos valores a utilizar como rango referencial en nuestra población; se sugiere utilizar estos valores como objetivo terapéutico en rehabilitación vestibular en pacientes evaluados en conjunto con otros parámetros clínico-sintomáticos.


Abstract Introduction: Posturography is a complementary method for evaluating the center of pressure (COP) displacement; it should not be used in isolation when assessing balance, but it is accepted for follow-up of the treatment response. Due to its high commercial cost and low availability, we documented the Nintendo Wii Balance Board (WBB) as an alternative for posturography. Aim: To describe the normal range of posturography parameters in the Chilean population without vestibular pathology, using a simple and accessible registry method. Material and Method: Cross-sectional study of referential values in a balance assessment tool. Posturography values were registered using an adapted version of the Sensory Organization Test (SOT) on healthy adults. Measurements with WBB Sway Program software through WBB. With adapted-SOT, somatosensory, visual and vestibular indices, as well as anterior/posterior and mediolateral axes postural control patterns, were measured. Results: Values of displacement velocity of the COP, COP area and corresponding standard deviations were obtained for 4 SOT-adapted situations from 35 subjects between 18-65 years, 21 women, 14 men. Discussion: As an approach to determine referential range values, WBB allowed to evaluate these parameters in healthy population. To determine healthy subjects postural control patterns this quick and accessible tool is a useful alternative. We present referential range values to use in our population; it is suggested to use these values as therapeutic objectives in vestibular rehabilitation in patients evaluated along with other clinical-symptomatic parameters.

ABSTRACT

Objetivo: Actualizar los resultados del registro BIOBADASAR sobre seguridad, duración y causas de interrupción del tratamiento luego de 8 años de seguimiento. Métodos: BIOBADASAR es un registro de seguridad de terapias biológicas establecido por la Sociedad Argentina de Reumatología. Se presenta la descripción de BIOBADASAR 3.0, una cohorte compuesta por 53 centros de Argentina seguidos prospectivamente desde agosto de 2010 hasta enero de 2018. Resultados: Se registraron 4656 pacientes, 6234 tratamientos [3765 casos (terapia con biológicos) y 2469 controles (terapia no biológicos)]. Se interrumpió el tratamiento en el 44,6% en los casos vs. 27,9% en los controles. Causa principal de discontinuación fue por ineficacia (40% casos vs. 32% controles). Se presentaron 3154 eventos adversos (2230 en casos vs. 924 en controles), de los cuales el 13,6% fueron graves (9,8% en casos y 3,7% en controles). El evento adverso (EA) más frecuente en ambos grupos fueron las infecciones (43,56% en casos vs. 34,31% en los controles, RR: 3,42; IC 95%: 3,02-3,88), y de ellas las de vías aéreas superiores (14,5%). Las neoplasias se presentaron en 78 casos vs. 45 en controles (RR: 1,98; IC 95%: 1,37-2,86). Conclusiones: En este sexto reporte no se observan tendencias diferentes sobre seguridad, duración y causas de interrupción del tratamiento respecto a informes previos. Las infecciones fueron el principal EA y la ineficacia, seguido por EA y la pérdida de pacientes las principales causas de suspensión del tratamiento. El advenimiento de nuevos agentes biológicos y la necesidad de control en seguridad a largo plazo, fortalece el uso de este tipo de registro.


Objective: Update the results of the BIOBADASAR registry on safety, duration and causes of treatment interruption after 8 years of follow-up. Methods: BIOBADASAR is a safety record of biological therapies established by the Argentine Society of Rheumatology. The description of BIOBADASAR 3.0 is presented, a cohort of 53 centers in Argentina followed prospectively from August 2010 to January 2018. Results: 4656 patients were registered, 6234 treatments [3765 cases (therapy with biologicals) and 2469 controls (non-biological therapy)]. Treatment was interrupted in 44.6% in cases vs. 27.9% in controls. Main cause of discontinuation was due to inefficiency (40% cases vs. 32% controls). There were 3154 adverse events (2230 in cases vs. 924 in controls), of which 13.6% were tombs (9.8% in cases and 3.7% in controls). The most frequent adverse event (AE) in both groups were infections (43.56% in cases vs. 34.31% in controls, RR: 3.42, 95% CI: 3.02-3.88), and the upper airway pathways (14.5%). Neoplasms were published in 78 cases versus 45 controls (RR: 1.98, 95% CI: 1.37-2.86). Conclusions: In this article, there are no different trends regarding safety, duration and causes of interruption of treatment compared to previous reports. Infections were the main causes of treatment discontinuation. The advent of new biological agents and the need for control over long-term security, strengthens the use of this type of registration.

ABSTRACT

Resumen Introducción: Existe una tendencia global al envejecimiento y con ello un aumento de patologías asociadas. En Chile la prevalencia de la colelitiasis o colecistolitiasis aumenta con la edad, siendo la cole-cistectomía una de las cirugías más frecuentes. Existen escasos estudios latinoamericanos referentes a la realidad de la población octogenaria expuesta a este problema. Objetivo: Estudiar la morbimortalidad posoperatoria en pacientes octogenarios operados de colecistectomía. Definir la precisión de distintas herramientas diagnósticas preoperatorias, estudiar variables operatorias y precisar costos hospitalarios. Materiales y Método: Estudio observacional retrospectivo de la ficha clínica electrónica del Hospital Clínico de la Universidad de Chile, entre enero de 2012 y mayo de 2017. Se incluyeron pacientes con edad igual o mayor a 80 años, en quienes se realizó una colecistectomía electiva o de urgencia por patología benigna. Resultados: Se incluyeron 145 pacientes, 51,7% fueron mujeres, el promedio de edad fue de 84,1 años y un 74,5% presentaba comorbilidades. El 62,1% de los casos ingresó por urgencia. 26,2% de toda la muestra presentó coledocolitiasis. La colecistectomía fue laparoscópica en 73,8% de la muestra global, la tasa de conversión fue de 14,5% en población de urgencia y 1,8% en población electiva (p = 0,009). La población operada totalmente por vía laparoscópica con coledocolitiasis fue resuelta en un 95,2% a través de Rendez-vous, con una tasa de éxito del 100%. La tasa de complicaciones fue de 17,9% siendo en su mayoría médicas, la mortalidad quirúrgica fue de 2,1%, siendo todos casos de urgencia. El costo promedio de atención en salud hospitalaria fue de $5.888.104 pesos chilenos (U$9.000). Conclusión: El paciente octogenario con colecistolitiasis representa un desafío quirúrgico, dado un mayor número de comorbilidades, un cuadro clínico más agresivo y una elevada tasa de coledocolitiasis. Es aconsejable valorar el abordaje mínimamente invasivo y realizar una colangiografía intraoperatoria de rutina.


Introduction: There is a global tendency to aging and associated pathologies. In Chile, the prevalence of cholecystolithiasis increases with age, cholecystectomy is one of the most frequent surgeries in the contry. There are few latinamerican studies regarding the reality of the elderly exposed to this problem. Objective: Study postoperative morbimortality in octogenarian patients undergoing cholecystectomy. Define the accuracy of different preoperative diagnostic tools, study operative variables and specify hospital costs. Materials and Method: Retrospective observational study of the Clinical Hospital of the University of Chile, between January 2012 and May 2017. Patients with age equal to or greater than 80 years were included, in whom an elective or emergency cholecystectomy was performed for benign pathology. Results: A total of 145 patients were included, 51.7% were women, the average age was 84.1 years, and 74.5% had comorbidities. The admission was throw the emergency department in 62.1% of the cases. Choledocholithiasis was diagnosed in 26.2% of the entire sample. Cholecystectomy was fully laparoscopic in 73.8% of the overall sample, the conversion rate was 14.5% in the emergency population and 1.8% in the elective population (p = 0.009). The population operated fully laparoscopically, that had choledocholithiasis, was resolved in 95.2% through Rendezvous technique, with a 100% clearance rate of common bile duct. The complication rate was 17.9%, most being medical. The surgical mortality was 2.1%, all cases operated from emergency. The average cost of hospital health care was $5,888,104.3 Chilean pesos (U$9.000). Conclusion: The octogenarian patient with cholecystolithiasis represents a surgical challenge, given a greater number of comorbidities, a more aggressive clinical setting and a high rate of choledocolithiasis. It is advisable to assess the minimally invasive approach and perform routine intraoperative cholangiography. In the postoperative period, the cardiopulmonary status and the infectious complications of the surgical site should be monitored closely.

ABSTRACT

El síndrome de encefalopatía posterior reversible (PRES) es una condición reversible, poco conocida en el lupus eritematoso sistémico (LES) que puede semejar al lupus neuropsiquiátrico. Las manifestaciones de PRES son cefalea, convulsiones, alteración del nivel de conciencia y amaurosis. En la mayoría de los casos, la TC (tomografía computarizada) del cerebro muestra lesiones hipodensas en el lóbulo parieto-occipital. Aunque este síndrome es poco común, el reconocimiento rápido y preciso permite un tratamiento temprano con resultados favorables. Presentamos un caso clínico de una paciente con debut de LES posterior a episodio de eclampsia, y que durante el puerperio tardío presenta hipertensión sostenida asociada a convulsiones y deterioro del nivel de conciencia en contexto de PRES


Posterior reversible encephalopathy syndrome (PRES) is a poorly recognized and reversible condition in systemic lupus erythematosus (SLE) that could mimic neuropsychiatric lupus. The manifestations of PRES are headache, seizures, altered level of consciousness and blindness. In most cases, computed tomography of the brain shows hypodense lesions in the parieto-occipital lobe. Although this syndrome is rare, rapid and accurate recognition allows early treatment with favorable results. We present a case report of a patient with the onset of SLE following the episode of eclampsia, and who during the late puerperium presented sustained hypertension associated with seizures and deterioration of the level of consciousness in the context of PRES.

ABSTRACT

La enfermedad de Still del adulto (ESA) es un proceso inflamatorio sistémico, de etiología desconocida, que se caracteriza por fiebre, artritis y eritema evanescente, además de valores elevados de ferritina sérica. Sin embargo, hasta la fecha, no hay una prueba definitiva de laboratorio o de imagen disponible para su diagnóstico, por lo tanto la ESA es un diagnóstico de exclusión. Presentamos el caso de una mujer de 44 años con manifestación cutánea atípica de ESA y cuadro clínico de 1 año de evolución caracterizado por fiebre de 40°C, linfadenopatía, hiperferritinemia, y que en la sistemática de estudio presentó positividad para anti-CCP (anticuerpo antipéptido cíclico citrulinado).


Adult Still's disease (ASD) is a systemic inflammatory process, of unknown etiology, characterized by fever, arthritis and evanescent erythema, in addition to elevated serum ferritin values. However, to date, there is no definitive laboratory or imaging test available to diagnose it, therefore ASD is a diagnosis of exclusion. We present the case of a 44-year-old woman with atypical cutaneous manifestation of ESA and positivity of ACPA (anti-cyclic citrullinated peptide antibody).

ABSTRACT

Pernio (chilblains) is an inflammatory condition classically characterized by localized erythema and swelling of acral sites upon exposure to cool and damp conditions. It is reported a case of a 59-year-old otherwise healthy woman with acute primary perniosis. She had a 3-day history of lesions on the toes brought on by cold, damp weather. On initial presentation, a biopsy sample was taken of a hallux lesion, and the patient was given a trial course of oral pentoxifylline, topical corticoid and nifedipine therapy. Follow-up at 2 weeks showed complete relief of symptoms and the biopsy results confirmed the diagnosis. Pentoxifylline therapy has been shown to be effective and should be considered the standard of care in the treatment of perniosis along with conservative environmental measures.The etiology and pathogenesis of perniosis are reviewed and discussed, as well as differential diagnoses and treatment options.

ABSTRACT

El síndrome antifosfolipídico fue descripto por Hughes y col. en 1983. Tiene múltiples manifestaciones clínicas en donde las vasculares y hemostáticas son las más prevalentes. Describimos cuatro casos que ilustran los problemas más comunes de la práctica clínica. El síndrome de Hughes ha extendido el uso del tratamiento antitrombótico al campo de la obstetricia donde la trombofilia es responsable de eventos serios como los abortos recurrentes. Esto es lo que justificó en nuestro hospital el funcionamiento de un consultorio de Hematología del Embarazo

ABSTRACT

INTRODUCTION: Antiphospholipid antibodies lupus anticoagulant (LA) and anticardiolipin antibodies (aCL) play a role in promoting arterial and venous thrombosis in several vascular territories. Acute vestibular syndromes are a common complaint in general and neurology practice. Approximately 9% of cases are due to central nervous system vestibular areas lesions, often associated with vascular disorders. OBJECTIVE: Define the potential relationship between these antibodies and central or peripheral vestibular failure. PATIENTS AND METHODS: We report the presence of antiphospholipid antibodies in 16 patients with central vestibular symptoms. All patients were seen in the Neuro otology and Vascular Neurology clinics at the Institute for Neurological Research in Buenos Aires. Magnetic resonance imaging (MRI) and ancillary neuro otologic tests were used to determine the etiology of vestibular manifestations. Determinations of LA and aCL were done using standard criteria. RESULTS: We evaluated 16 patients (13 women and 3 men), aged 44 4 years (21 65). Thirteen patients did not have stroke risk factors. MRI lesions were found in 11 subjects (1 cerebellar infarct, 3 pontine ischemic changes, and 9 white matter abnormalities). All patients had signs consistent with dysfunction of vestibulo cerebellar structures or the vestibular nuclei. All patients had positive LA and 4 of them had also elevated aCL. CONCLUSION: Our findings suggest a potential association between the presence of a prothrombotic state and central vestibular dysfunction of vascular etiology. To the best of our knowledge, this is the first report of such an association in the absence of clinically evident autoimmune disease.

ABSTRACT

Introducción. Los anticuerpos antifosfolipídicos (AF) -anticoagulante lúpico (AL) y anticardiolipinas (aCL)- desempeñan un papel que promueve trombosis arterial y venosa en diferentes territorios vasculares. Los síndromes vestibulares agudos representan una afección frecuente en la práctica neurológica. Aproximadamente el 9 per cent de los casos se deben a lesiones en áreas del sistema vestibular central, siempre asociadas con desórdenes vasculares. Objetivo. Definir la posible relación entre estos anticuerpos y los fallos vestibulares. Pacientes y métodos. Comunicamos la presencia de AF en 16 pacientes con síntomas vestibulares centrales. Todos los pacientes se evaluaron en el sector Neuro-Otológico y Vascular del Instituto de Investigaciones Neurológicas de Buenos Aires (FLENI) (1998-2000).Se realizó resonancia magnética cerebral (RMC) y tests neurootológicos para determinar la topografía y etiología de dichos síntomas.La determinación de AL y aCL se realizaron con los criterios estándar. Resultados. Evaluamos 16 pacientes (13 mujeres y tres hombres), de 44 ñ 4 años (21-65), trece de ellos sin factores de riesgo vascular. En 10 sujetos observamos lesiones en la RMC (un infarto de cerebelo, tres isquemias de protuberancia y ocho infartos en la sustancia blanca). Todos tenían signos de disfunción vestibulocerebelosa o de los núcleos vestibulares. Los 16 fueron positivos para AL y cuatro de ellos presntaron los aCL elevados. Conclusión. Estos hallazgos sugieren una asociación entre la existencia de un estado protrombótico y una disfunción vestibular central de etiología vascular. Este es el primer informe que relaciona dicha asociación en ausencia de patología autoinmune clínica evidente . Debería considerarse la determinación de AL y aCL en pacientes con manifestaciones vestibulares (AU)
