Rescate con rituximab en paciente con liquen plano esofágico refractario

Esophageal lichen planus (ELP) is a rare condition with unknown prevalence that can sometimes be underestimated due to the subtle and nonspecific findings of diagnostic workup. Oral lesions rarely extend to the esophageal mucosa, but when they do, the most frequent symptoms are dysphagia and odynophagia. There is often a significant delay in diagnosis and inadequate treatment. We report the case of a 59-year-old woman diagnosed with ELP, successfully treated with rituximab, a chimeric monoclonal antibody that depletes CD20+B cells. To our knowledge, this is only the second report of this treatment in ELP.     

Electromiografía laríngea en el diagnóstico y tratamiento de los trastornos de la voz

Introduction and objectivesLaryngeal electromyography, together with clinical evaluation, is a valuable tool in voice disorder management. It assesses the integrity of laryngeal nerves and muscles, contributing to the diagnosis of many diseases, especially laryngeal movement disorders. Our purpose was to describe the experience of the first Spanish series with laryngeal electromyography in evaluating voice disorders.MethodsA prospective study was designed to evaluate laryngeal movement disorders with laryngeal electromyography. Both the cricothyroid and thyroarytenoid muscles were tested routinely and, in some cases, the posterior cricoarytenoid muscle. The laryngeal electromyography technique and result interpretation were performed by a laryngologist and a neurophysiologist.ResultsWe included 110 patients, with the most common symptom being dysphonia. Laryngeal electromyography was performed in 85% of cases. Primary diagnosis before electromyography was laryngeal immobility. Positive predictive value for diagnosis in cases of paralysis was 88%.ConclusionsLaryngeal electromyography is a useful adjunct, together with clinical evaluation, for diagnosis and management of motion abnormalities in the larynx in patients who present with dysphonia.     

Una causa excepcional de hepatitis aguda en el adulto: parvovirus B19

There are multiple causes of hepatitis. The most frequent etiologies are viral, usually hepatitis A, B and C viruses. However, other, non-hepatotropic viruses can cause this disease, including parvovirus B19. We present a case of acute hepatitis due to parvovirus B19, as well as a review of the epidemiological, clinical, diagnostic and therapeutic features of this entity.
