Introducción La osteonecrosis avascular (ONA) de cadera y de hombro es una enfermedad poco estudiada y no se conocen bien los factores de riesgos predisponentes para desarrollarla. Existe un porcentaje alto de pacientes diagnosticados como osteonecrosis idiopática. Este estudio tiene como objetivo investigar la prevalencia de los posibles factores etiológicos de la ONA y realizar un cribado de la enfermedad de Gaucher en los pacientes diagnosticados de ONA idiopática. Material y método Estudio observacional retrospectivo y unicéntrico de los pacientes que hayan presentado al menos un episodio de osteonecrosis avascular de la cadera o del hombro en el Hospital de Poniente (Almería, España) desde enero de 2010 a diciembre de 2019. Se recogieron datos clínicos y analíticos. Los pacientes en cuya historia clínica no se describían factores etiológicos fueron cribados para enfermedad de Gaucher. Resultados Se incluyeron un total de 81 pacientes, de los cuales 58 eran hombres. La edad media de presentación de ONA fue de 45,9 años. Presentaron necrosis unilateral de cadera (n = 43), necrosis bilateral de cadera (n = 34), necrosis bilateral de cadera y unilateral de hombro (n = 3) y necrosis unilateral de hombro (n = 1). Los potenciales factores etiológicos más frecuentes fueron tabaquismo (46,9%) y obesidad (17,3%). Se realizó un cribado de la enfermedad de Gaucher en 10 pacientes, que resultó ser negativo. Conclusiones En nuestro estudio los principales potenciales factores etiológicos de aparición de la ONA fueron el tabaquismo y la obesidad. Existe un porcentaje alto de pacientes diagnosticados de osteonecrosis avascular idiopática. Creemos que en estos casos se debería realizar un estudio más exhaustivo de los factores de riesgo menos frecuentes (AU)
Introduction Avascular necrosis (AON) of the hip and shoulder is a little studied disease and the predisposing risk factors for its development are not well known. A high percentage of patients are diagnosed with idiopathic osteonecrosis. This study aims to investigate the prevalence of potential etiological factors for AON and to screen for Gaucher disease among patients with idiopathic AON. Material and methods This retrospective, single-center, observational study was conducted on patients who had at least one episode of AON of the hip or shoulder at the Hospital de Poniente (Almería, Spain) from January 2010 to December 2019. Clinical and analytical data were collected. Patients whose medical record described no etiological factors for this disease were screened for Gaucher disease. Result The study sample consisted of 81 patients, of whom 58 were male. The mean age at presentation of AON was 45.9 years. They presented with unilateral hip necrosis (n = 43), bilateral hip necrosis (n = 34), bilateral hip and unilateral shoulder necrosis (n = 3), and unilateral shoulder necrosis (n = 1). The most frequent potential etiological factors were smoking (46.9%) and obesity (17.3%). Screening for Gaucher disease was performed in ten patients, all of whom tested negative. Conclusions In our study population, the main potential etiological factors the onset of AON of the shoulder or hip were smoking and obesity. A high percentage of patients were diagnosed with idiopathic AON. We believe that a more exhaustive study of less frequent risk factors should be carried out in these cases (AU)

Objetivos. Blastocystis hominis (B. hominis) es uno de los parásitos intestinales más frecuentemente aislados en el ser humano. Puede producir sintomatología gastrointestinal o, en la mayoría de los casos, permanecer asintomático. Existen dudas sobre el carácter patógeno del parásito. El objetivo de este estudio fue analizar las características clínicas y epidemiológicas de la parasitación por B. hominis, con y sin otras coparasitaciones. Pacientes y métodos. Estudio observacional retrospectivo de aislamientos de B. hominis en heces, desde octubre del 2004 hasta marzo del 2016 en una Unidad de Medicina Tropical. Se revisó a todos los pacientes con parasitación exclusiva, o no, por B. hominis. Resultados. Se estudió a 3.070 pacientes. En 570 (18%) se diagnosticó infección por B. hominis, de los que en 245 (43%) representó el único aislamiento; 325 (57%) presentaron otras coparasitaciones (Entamoeba hystolitica o dispar, Strongyloides stercoralis, uncinarias y Schistosoma sp.). El síntoma principal fue dolor abdominal (41,8%). En un 31,2% el parásito se detectó en el cribado de enfermedades importadas en pacientes asintomáticos. De los que recibieron tratamiento con metronidazol, un 78,2% mejoró y en el 82,6% los parásitos se negativizaron. Conclusiones. La parasitación por B. hominis es una de las enfermedades más frecuentes en nuestra Unidad de Medicina Tropical. La mayoría de los pacientes están asintomáticos o bien la clínica puede ser atribuida a otras parasitaciones. En aquellos casos en los que persisten los síntomas sin poder ser atribuidos a otras causas, es recomendable un tratamiento específico
Objectives. Blastocystis hominis (B. hominis) is one of the most common intestinal parasites isolated in humans. The parasite can cause gastrointestinal symptoms or, in most cases, remain asymptomatic. There are issues concerning the parasite's pathogenic character. The aim of this study was to analyse the clinical and epidemiological characteristics of the parasite infection by B. hominis, with or without other parasitic co-infections. Patients and methods. An observational retrospective study was conducted of B. hominis isolates in faeces from October 2004 to March 2016 in a tropical medicine unit. We reviewed all patients with a parasite infection, exclusively or not by B. hominis. Results. We studied 3070 patients, 570 (18%) of whom were diagnosed with B. hominis infection, which was the only isolate in 245 (43%) of the 570 patients. A total of 325 (57%) patients presented other parasitic co-infections (Entamoeba histolytic or Entamoeba dispar, Strongyloides stercoralis, hookworm and Schistosoma spp.). The main symptom was abdominal pain (41.8%). In 31.2% of cases, the parasite was detected in the imported diseases screening of asymptomatic patients. Of those who underwent treatment with metronidazole, 78.2% improved. The parasite was neutralised in 82.6% of the patients. Conclusions. Parasite infection by B. hominis is one of the most common diseases in our tropical medicine unit. Most patients are asymptomatic, or their symptoms can be attributed to other parasite infections. In those cases in which symptoms persist without being able to attribute them to other causes, a specific treatment is recommended
