RESUMEN
El Síndrome de Ramsay Hunt es una entidad infrecuente, con una incidencia de 5 por cada 100.000 personas por año. Esta condición se caracteriza por una reactivación del virus de la varicela-zoster en el nervio facial. Su diagnóstico implica un reto para el médico puesto que suele ser netamente clínico, con la aparición de una triada consistente en: otalgia, parálisis facial ipsilateral y vesículas en el canal auditivo. El objetivo del artículo es presentar el caso de una mujer de 49 años de edad, con antecedente de epilepsia en tratamiento anticonvulsivante, quien ingresa con la triada clínica antes descrita, asociada a visión borrosa derecha y vértigo. La paciente fue tratada con antivirales y corticoides orales, presentando una resolución clínica favorable dado una reducción de más del 50% de las lesiones cutáneas. No se identificaron diferencias respecto a la presentación clínica de este síndrome al compararse con pacientes no epilépticos.
Ramsay Hunt Syndrome is a rare entity, with an incidence of 5 per 100,000 people per year. This condition is characterized by a reactivation of the varicella-zoster virus in the facial nerve. Its diagnosis implies a challenge for the physician since it is usually a clinical diagnosis, with the appearance of a clinical triad consisting of: otalgia, ipsilateral facial paralysis and vesicles in the ear canal. The objective of the article is to present the case of a 49-year-old woman, with a history of epilepsy receiving anticonvulsant treatment, who was admitted with the aforementioned clinical triad, associated with blurred right vision and vertigo. The patient was treated with oral antiviral management and oral corticosteroids, presenting a favorable clinical resolution given a reduction of more than 50% of the skin lesions. No differences were identified regarding the clinical presentation of this syndrome when compared with non-epileptic patients.
RESUMEN
INTRODUCTION: Additional cytogenetic abnormalities (ACA) in patients with chronic myeloid leukemia (CML) are related to an increased risk of treatment failure, leukemic progression, and decreased survival. Currently, there are scarce data available for the Latin American population. The aim of this study was to outline the impact of ACA emergence in Mexican patients with CML. METHODS: We retrospectively analyzed clinical data from adult patients with CML treated with upfront imatinib between January 2001 and December 2016. Two groups were defined for comparison according to the presence or absence of ACA. RESULTS: Ninety-seven patients were included. ACAs were found in 30 patients, 20% at diagnosis and 80% during follow-up. In 90% of the patients, ACA emergence was detected in the CML-chronic phase. Regarding clinical outcomes, the complete cytogenetic response rate (16.5% vs. 59.8%; P < .001), progression-free survival (PFS) at 10 years (76% vs. 95%; P = .009), and failure-free survival (FFS) at 10 years (16% vs. 73%; P < .001) were significantly inferior in the ACA group. Multivariate analysis confirmed that ACA emergence was a deleterious independent prognostic factor for PFS (hazard ratio [HR] 8.9; 95% confidence interval [CI] 1.35-58.4; P = .023) and FFS (HR 3.7; 95% CI 1.54-8.58; P = .003). CONCLUSIONS: This study confirms previously reported data regarding the adverse impact of ACA over clinical outcomes in a Latin American population.
