Miocardiopatías restrictivas: Valoración por resonancia magnética cardiaca y tomografía multicorte / Restrictive Cardiomyopathies: Evaluation Using Cardiac MRI and Multidetector CT

Las miocardiopatías son condiciones que afectan al miocardio y generan alteración en la función cardiaca. Dentro de las miocardiopatías, el subgrupo de las restrictivas tiene como principal hallazgo la disminución en el llenado ventricular. A continuación se expone una revisión acerca de las miocardiopatías restrictivas, se analizan sus principales causas, y los hallazgos por resonancia magnética cardiaca y por tomografía computarizada. También se incluyen signos por imagen que ayudan a diferenciar las miocardiopatías restrictivas de la pericarditis constrictiva.

Cardiomyopathies are conditions that affect the myocardium and cause alteration in the cardiac function. Within the cardiomyopathies, the restrictive subgroup has as a main finding the decrease in the ventricular filling. In this manuscript we will review the restrictive cardiomyopathies and discuss their main causes, as well as their imaging findings on cardiac magnetic resonance and computed tomography. We will also include imaging signs that helps to differentiate restrictive cardiomyopathies from constrictive pericarditis.

Úlceras en intestino delgado por glucosamina con MSM: Reporte de un caso / Case report: Ulcers in the small intestine due to glucosamine and methylsulfonylmethane (MSM) use

Reportamos el caso de una paciente con dolor abdominal, anemia por deficiencia de hierro y sangre oculta positiva en materia fecal. Sin sangrado evidente. Historia de osteoartritis en manejo con glucosamina con metilsulfonilmetano. Endoscopia superior y colonoscopia no explican sangrado. Cápsula endoscópica muestra múltiples úlceras circunferenciales algunas de ellas con sangrado activo. Se descarta uso de AINES y enfermedad de Crohn. Al mes de suspender suplemento nutricional hay resolución de síntomas y de anemia con sangre oculta negativa. No hubo recurrencia de síntomas.

We report on the case of a female patient with abdominal pain, iron deficiency anemia who tested positive for fecal occult blood but had no overt gastrointestinal bleeding. Patient had a known history of osteoarthritis and used Glucosamine - MSM. Both upper GI endoscopy and colonoscopy were negative. Capsule endoscopy showed multiple concentric ulcers, several of which were actively bleeding. Patient reported no use of NSAIDs, and there was no evidence of Crohn's disease. Nutritional supplements were stopped. After four weeks abdominal pain improved, patient had anemia and a fecal occult blood test was negative. Symptoms have not recurred.
