Paraganglioma carotídeo maligno. A propósito de un caso / Malignant carotid paraganglioma: a case report

Los tumores del cuerpo carotídeo son neoplasias poco frecuentes, de lento crecimiento, muy destructivos y vascularizados, que tienen un origen neuroectodérmico. Los tumores malignos representan el 5-13% de los casos y presentan un comportamiento agresivo local con infiltración de los ganglios linfáticos adyacentes o metástasis a distancia. Presentamos el caso de un varón de 60 años al que en el estudio por dolor y parestesias en miembro superior se le realiza una resonancia magnética donde se visualiza una gran tumoración en el espacio carotídeo izquierdo, la cual se biopsió obteniendo el diagnóstico histológico de paraganglioma. Al realizar el estudio de extensión se identificó la presencia de metástasis pulmonares y óseas, lo que confirma la malignidad del tumor

Tumors of the carotid body are uncommon neoplasms that originate in the neuroectoderm. These tumors are slow growing but well vascularized and very destructive. Between 5% and 13% of carotid body tumors are malignant, behaving aggressively at the local level, invading the adjacent lymph nodes, and resulting in remote metastases. We present the case of a 60-year-old man who was examined for pain and paresthesias in his arm. Magnetic resonance imaging showed a large tumor in the left carotid space. Histologic study of a biopsy specimen from the tumor revealed that it was a paraganglioma. Further studies to determine the extent of disease detected metastases in bone and lung, confirming the tumor's malignancy

Prevalencia de sarcopenia en una unidad de media y larga estancia / Prevalence of sarcopenia in a media and long stay Unit

Antecedentes. La sarcopenia se caracteriza por la pérdida de masa y fuerza muscular esquelética y representa un factor de riesgo de fragilidad, pérdida de independencia y discapacidad física. Este estudio pretende valorar la prevalencia de sarcopenia en una población de pacientes ingresados en una unidad de media-larga estancia. Pacientes y métodos. Estudio descriptivo, longitudinal y observacional que incluyó a 166 pacientes mayores de 18 años ingresados de forma consecutiva durante un año para tratamiento paliativo, convalecencia o rehabilitación. Se registraron datos administrativos y antropométricos. La detección de sarcopenia se realizó mediante la valoración de la fuerza muscular en cintura escapular y pélvica, fuerza prensil en manos, masa muscular y de la capacidad funcional física. Resultados. La prevalencia global de sarcopenia fue del 77,6%. La mayor parte de los pacientes con sarcopenia presentaban sarcopenia severa (91,2%), con los 3 parámetros valorados disminuidos: fuerza muscular (88,2%), masa muscular (85,5%) y rendimiento físico (94,70%). Conclusiones. La prevalencia de sarcopenia en los pacientes ingresados en nuestra unidad de media-larga estancia es muy elevada, superior a la descrita en población no institucionalizada, y con frecuencia tiene un grado importante de severidad (AU)

Background. Sarcopenia is characterized by the loss of skeletal muscle mass and strength and represents a risk factor for frailty, loss of independence and physical disabilities. This study aimed to assess the prevalence of sarcopenia in a population of patients admitted to a media and long-stay unit. Patients and methods. Descriptive, cross-sectional observational study that included 166 patients over 18 years who were admitted consecutively for a year to palliative care, convalescence or rehabilitation. Administrative and anthropometric data were recorded. Sarcopenia detection was performed by assessing the strength in the scapular and pelvic girdle muscles, grip strength in the hands, muscle mass and physical functional capacity. Results. The overall prevalence of sarcopenia was 77.6%. Most patients had severe sarcopenia (91.2%), with reduced levels of the 3 assessed parameters: muscle strength (88.2%), muscle mass (85.5%) and physical performance (94.70%). Conclusion. The prevalence of sarcopenia in patients admitted to our media and long-stay unit is higher than that reported in noninstitutionalized populations, and often has a significant degree of severity (AU)
