Restless legs syndrome in patients with multiple sclerosis: evaluation of risk factors and clinical impact.

INTRODUCTION: Restless legs syndrome (RLS) is a disorder characterised by an irresistible urge to move the legs, usually accompanied by unpleasant sensations. It is more frequent in patients with multiple sclerosis (MS) than in the general population. OBJECTIVES: To evaluate the prevalence of RLS, defined according to the 4 essential requirements included in the diagnostic criteria proposed by the International Restless Leg Syndrome Study Group, in a cohort of patients with MS; and to identify potential risk factors and the clinical impact of RLS. RESULTS: The sample included 120 patients with MS, with a mean age of symptom onset of 40 years and an average disease duration of 46 months. The prevalence rate of RLS was 23.3%. MS progression time was significantly shorter in patients with RLS (P=.001). A recent relapse, and symptoms of anxiety, depression, and neuropathic pain were significantly associated with risk of RLS (P=.001, P<.001, P<.001, and P=.001, respectively). In addition, patients with RLS had a greater risk of poor sleep quality, fatigue, daytime sleepiness, and poor quality of life than those without RLS (P=.002, P=.017, P=.013, and P=.009, respectively). CONCLUSIONS: RLS should be considered in the neurological evaluation of patients with MS; early diagnosis and treatment would improve the quality of life of patients with MS presenting RLS.

Síndrome de piernas inquietas en esclerosis múltiple: evaluación de factores de riesgo y repercusión clínica / Restless legs syndrome in patients with multiple sclerosis: evaluation of risk factors and clinical impact

Introducción: El síndrome de piernas inquietas (SPI) es un trastorno caracterizado por la necesidad imperiosa de mover las piernas, estando a menudo acompañado de sensaciones desagradables. Su frecuencia es superior en pacientes con esclerosis múltiple (EM) que en la población general. Objetivos: Evaluar la prevalencia del SPI, según el cumplimiento de los 4 requisitos esenciales incluidos en los criterios diagnósticos propuestos por la International Restless leg syndrome study group (IRLSSG, 2003), en una cohorte de pacientes con EM e identificar posibles factores de riesgo y repercusión clínica. Resultados: Se incluyeron 120 pacientes con EM, con una edad media de inicio de 40 años y un tiempo medio de evolución de 46 meses. La prevalencia de SPI, según el cumplimiento de criterios diagnósticos de la IRLSSG, fue del 23,3%. El tiempo de evolución de EM, desde la aparición de los primeros síntomas, fue significativamente menor en pacientes con SPI (p=0,001). La presencia de un brote reciente, así como de síntomas de ansiedad, depresión y dolor neuropático se asociaron de forma significativa con el riesgo de SPI (p=0,001, p<0,001, p<0,001 y p=0,001, respectivamente). Además, los pacientes con SPI y EM presentaron mayor riesgo de mala calidad de sueño, fatiga, somnolencia diurna y peor calidad de vida, que aquellos sin SPI (p=0,002, p=0,017, p=0,013 y p=0,009, respectivamente). Conclusiones: El SPI debe ser considerado en la evaluación neurológica de pacientes con EM, cuyo diagnóstico y tratamiento precoz mejoraría la calidad de vida de estos sujetos. (AU)

Rendimiento diagnóstico de la histerosalpingografía por resonancia magnética: resultados iniciales / Diagnostic performance of magnetic resonance hysterosalpingography: initial results Abstract

Objetivo: Determinar el rendimiento diagnóstico de la histerosalpingografía por resonancia magnética (HSG-RM), utilizando la laparoscopia como método de referencia. Materiales y métodos: Se incluyeron 22 pacientes. A todas se les realizó una HSG-RM con un resonador 1.5 Tesla y luego una laparoscopia con cromotubación. Dos radiólogos examinaron las RM, determinando la permeabilidad tubaria por consenso. Se realizaron análisis descriptivos y de rendimiento diagnóstico. Resultados: La HSG-RM tuvo una tasa de éxito del 91%. La duración del estudio fue 49ą15 minutos, el volumen inyectado 26 ą 16 cm³ y la escala de dolor 30ą 19 de 100. La sensibilidad y especificidad de la HSG-RM fueron del 100% para la prueba de Cotte global y a la izquierda, y del 25% y 93,3% para la prueba de Cotte a la derecha, respectivamente. Hubo 2 complicaciones menores y ninguna importante. Discusión: Nuestros resultados iniciales demostraron una alta sensibilidad y especificidad. Si bien otros estudios analizaron la capacidad de la HSG-RM para evaluar la permeabilidad tubaria con buenos resultados, el uso de un patrón de referencia defectuoso dejaba margen para una duda razonable, impidiendo una recomendación basada en pruebas sólidas. Sin embargo, al cotejar nuestros resultados con los publicados, observamos un alto grado de concordancia en tanto el derrame positivo se diagnostica correctamente con una especificidad de 100% o con un porcentaje cercano a esta cifra. Conclusión: La HSG-MR es una alternativa factible y segura de la HSG convencional o virtual, la histerosonografía y la cromotubación.

Objective: To determine the diagnostic performance of magnetic resonance hysterosalpingography (MRHSG) using laparoscopic chromotubation as a method of reference. Materials and methods: Twenty-two patients were included. The MRHSG was performed in a 1.5 Tesla MR scanner. Afterwards, patients underwent laparoscopic chromotubation. MR images were examined by two trained radiologists, and tubal patency was determined by consensus. A descriptive analysis was carried out, as well as an analysis of the diagnostic performance. Results: MRHSG had a 91% success rate. Exam duration of the examination was 49ą15min, with an injected volume 26ą 16cc, and pain scale 30ą 19 out of 100. Sensitivity and specificity of MRHSG was 100% for global and left Cotte, and 25% and 93.3% for right Cotte, respectively. Only 2 minor and no major complications were observed. Discussion: The initial results of MRHSG have shown high sensitivity and specificity. Even though other studies have analysed the potential of MRHSG with good results, the use of a flawed reference standard left a margin for a reasonable doubt as regards its true potential, thus preventing a solid evidence based recommendation. Nevertheless, if our results are compared to those published, a high level of agreement is observed in that positive spillage is correctly diagnosed with specificities near or at 100%. Conclusion: MRHSG is a feasible and safe alternative to conventional or virtual HSG, ultrasound-hysterography and chromotubation.

[Retrograde intramedullary nail fixation for Charcot neuroarthropathy]. / Evaluación del uso del clavo centromedular retrógrado bloqueado para artrodesis de tobillo en pacientes con neuroartropatía de Charcot.

Charcot arthropathy is defined as an articular degenerative, chronic, progressive disease that affects one or more peripheral joints, develops as a result of a failure in the normal sensory perception (pain and proprioception) in the innervation of joints located in the foot and ankle, is characterized by destructive bone lesions without the presence of infection. Neuropathy is directly associated with diabetes mellitus type 1 and 2. Surgery is indicated when there is severe involvement of soft tissue, foot joints are unstable, at the presence of chronic or recurrent ulcers or when the foot and ankle can not fit to a normal shoe, and had limitation to perform activities of daily living. MATERIAL AND METHODS: Charcot arthropathy is defined as an articular degenerative, chronic, progressive disease that affects one or more peripheral joints, develops as a result of a failure in the normal sensory perception (pain and proprioception) in the innervation of joints located in the foot and ankle, is characterized by destructive bone lesions without the presence of infection. Neuropathy is directly associated with diabetes mellitus type 1 and 2. Surgery is indicated when there is severe involvement of soft tissue, foot joints are unstable, at the presence of chronic or recurrent ulcers or when the foot and ankle can not fit to a normal shoe, and had limitation to perform activities of daily living. DESIGN: observational, prospective, transversal, descriptive. SAMPLE: patients diagnosed with Charcot neuropathy type 3a of Brodsky. Surgically treated by ankle arthrodesis with an intramedullary blocked nail, from January 2010 to August 2015. RESULTS: 16 patients were analyzed. Preoperative AOFAS score was 35.0 ± 5.2 points. Postoperative follow-up period of 4 years to 7 months. Postoperative AOFAS scale showed an improvement of 40 points (p = 0.0001). CONCLUSIONS: The proposed treatment allows bone stabilization, resulting in a full foot plantar support and decreases the occurrence of chronic ulcers that are difficult to treat, and is an alternative method that avoids lead to amputation.

La artropatía de Charcot se define como un padecimiento articular degenerativo, crónico y progresivo que se caracteriza por lesiones óseas destructivas sin presencia de infección. La neuropatía está asociada directamente con la diabetes mellitus tipo 1 y 2. La cirugía está indicada cuando existe compromiso de partes blandas, inestabilidad de las articulaciones del tobillo y pie, cuando se desarrollan úlceras recurrentes o no es posible adecuar el tobillo o el pie a un calzado normal o en los pacientes que presentan deformidad severa, úlceras o dolor crónico y limitación para realizar las actividades de la vida diaria. El presente es un trabajo observacional, prospectivo, transversal y descriptivo de pacientes con diagnóstico de neuroartropatía de Charcot tipo 3a de Brodsky tratados quirúrgicamente mediante artrodesis de tobillo con clavo centromedular retrógrado bloqueado, del 1o de Enero de 2010 al 31 de Agosto de 2015. Se analizaron 16 pacientes. En el preoperatorio la media de la escala de AOFAS fue de 35.0 ± 5.2 puntos. Un seguimiento postoperatorio de cuatro años con un mínimo de siete meses. En el postoperatorio la escala de AOFAS mostró un incremento de 40 puntos hacia la mejoría (p = 0.0001). La técnica revisada logra la estabilización ósea, resultando en un pie con apoyo plantígrado que disminuye la aparición de úlceras crónicas y mejora el desarrollo en las actividades de la vida cotidiana.
