Clinical and subclinical cardiovascular disease in female SLE patients: Interplay between body mass index and bone mineral density.

BACKGROUND AND AIMS: Since accelerated atherosclerosis has been reported in systemic lupus erythematosus (SLE), predictive biomarkers of cardiovascular disease (CVD) are needed. Among non-traditional risk factors, bone mineral density (BMD) has been related to CVD. However, its role in SLE remains controversial. This study aims to analyze the associations of subclinical atherosclerosis with traditional and non-traditional CV risk factors. METHODS AND RESULTS: In a cross-sectional study, atherosclerosis burden was compared between 112 female SLE patients and 31 controls. Plaque number and carotid intima-media wall thickness (cIMT) were assessed by ultrasonography. In a retrospective study, BMD determinations obtained 5-years before the ultrasonography assessment were analyzed in a subgroup of 62 patients. Plaque frequency was increased in SLE, even in patients without CV events or carotid wall thickening. cIMT was increased in patients with CVD, positively correlated with body mass index (BMI). Interestingly, a paradoxical effect of BMI on carotid parameters was observed. Whereas underweight patients (BMI < 20) showed increased prevalence of carotid plaques with low cIMT, those with BMI > 30 showed higher cIMT and plaque burden. Overweight patients (25 < BMI<30) exhibited both elevated cIMT and plaque number. BMI was an independent predictor of BMD. In our retrospective study, patients with either clinical or subclinical CVD exhibited lower BMD levels than their CV-free counterparts. A low lumbar spine BMD independently predicted CVD development after adjusting for confounders. CONCLUSION: SLE was associated with a higher subclinical atherosclerosis burden, a bimodal effect being observed for BMI. Decreased BMD can be a CV risk biomarker in SLE.

[Appraisal of cerebral atrophy in multiple sclerosis by means of the corpus callosum index]. / Valoracion de la atrofia cerebral en la esclerosis multiple mediante el indice de cuerpo calloso.

INTRODUCTION: The course of multiple sclerosis is characterised by the development of cerebral atrophy. It is of interest to monitor it in order to evaluate the treatment response, and the preferred technique consists in performing brain volume analyses, which are currently restricted to the field of research. AIM: To analyse the corpus callosum index (CCI) as a possible alternative to the methods based on brain segmentation. SUBJECTS AND METHODS: Our sample was made up of 109 patients with recently diagnosed demyelinating diseases (90 relapsing-remitting multiple sclerosis, 7 primary progressive forms and 12 isolated demyelinating syndromes), and the CCI was calculated in their first magnetic resonance brain scan, together with 101 healthy controls. The sequences of the patients were submitted to a volumetric analysis using the software package MSmetrix. RESULTS: The mean value of the CCI was 0.377 in patients and 0.411 in the controls, and the difference was statistically significant (p < 0.001). The CCI also showed a statistically significant correlation with the brain volume (p < 0.001; r = 0.444) and with the lesional volume in the FLAIR sequence (p < 0.001; r = -0.521), while no association was observed with the volume of grey matter (p = 0.058). CONCLUSIONS: The CCI is related to the overall brain volume obtained by volumetric techniques and may reflect the presence of atrophy in the initial stages of demyelinating diseases, which makes it a fast and easy to calculate alternative.

TITLE: Valoracion de la atrofia cerebral en la esclerosis multiple mediante el indice de cuerpo calloso.Introduccion. La esclerosis multiple se caracteriza en su evolucion por el desarrollo de atrofia cerebral. Su monitorizacion resulta de interes para evaluar la respuesta al tratamiento, y son de eleccion los analisis volumetricos cerebrales, actualmente confinados al ambito de la investigacion. Objetivo. Analizar el indice de cuerpo calloso (ICC) como una posible alternativa a los metodos basados en la segmentacion cerebral. Sujetos y metodos. Se reune a 109 pacientes con enfermedades desmielinizantes de reciente diagnostico (90 con esclerosis multiple remitente recurrente, 7 con formas primarias progresivas y 12 con sindrome desmielinizante aislado) y se calcula el ICC en su primer estudio de resonancia magnetica cerebral, asi como en 101 controles sanos. Las secuencias de los pacientes se someten a analisis volumetrico mediante el programa MSmetrix. Resultados. El valor medio del ICC es de 0,377 en los pacientes y 0,411 en los controles, y la diferencia es estadisticamente significativa (p < 0,001). El ICC muestra una correlacion estadisticamente significativa con el volumen encefalico (p < 0,001; r = 0,444) y con el volumen lesional en secuencia FLAIR (p < 0,001; r = ­0,521), mientras que no se demuestra asociacion con el volumen de la sustancia gris (p = 0,058). Conclusiones. El ICC se relaciona con el volumen encefalico global obtenido mediante tecnicas volumetricas y puede reflejar la presencia de atrofia ya en los estadios iniciales de las enfermedades desmielinizantes, por lo que se presenta como una alternativa de rapido y sencillo calculo.

Análisis del primer año del nuevo protocolo de código ictus en Asturias. Experiencia de un único centro / Analysis of the new code stroke protocol in Asturias after one year. Experience at one hospital

Introducción: Los sistemas de código ictus prehospitalario han demostrado ser eficaces en la mejoría del acceso a una atención médica especializada en el ictus agudo y en condicionar un mejor pronóstico en la enfermedad, que es una de las principales causas de muerte y discapacidad en nuestro medio. El objetivo de este estudio es analizar los resultados del primer año de puesta en marcha del nuevo protocolo de código ictus (CI) en Asturias en un solo centro. Pacientes y métodos: Se incluye de forma prospectiva a los pacientes que acuden dentro del protocolo de código ictus a un centro de tercer nivel asistencial durante el periodo de un año. Resultados: Se analiza a 363 pacientes. La edad media fue de 69 años y en el 54% de los casos se trataba de varones. Para el mismo periodo del año previo las activaciones extrahospitalarias de CI fueron 236. Se llevaron a cabo 147 tratamientos recanalizadores (66 fibrinólisis y 81 trombectomías mecánicas o tratamientos combinados), lo que supuso un incremento del 25% con respecto al año previo. Conclusiones: Los recientes avances en la terapéutica del ictus agudo hacen necesaria la instauración de protocolos coordinados de CI que se adapten a las necesidades de cada región concreta, lo que puede resultar en un incremento del número de pacientes atendidos precozmente, así como de los tratamientos revascularizadores realizados (AU)

Introduction: Prehospital code stroke (CS) systems have been proved effective for improving access to specialised medical care in acute stroke cases. They also improve the prognosis of this disease, which is one of the leading causes of death and disability in our setting. The aim of this study is to analyse results one year after implementation of the new code stroke protocol at one hospital in Asturias. Patients and methods: We prospectively included patients who were admitted to our tertiary care centre as per the code stroke protocol for the period of one year. Results: We analysed 363 patients. Mean age was 69 years and 54% of the cases were men. During the same period in the previous year, there were 236 non-hospital CS activations. One hundred forty-seven recanalisation treatments were performed (66 fibrinolysis and 81 mechanical thrombectomies or combined treatments), representing a 25% increase with regard to the previous year. Conclusions: Recent advances in the management of acute stroke call for coordinated code stroke protocols that are adapted to the needs of each specific region. This may result in an increased number of patients receiving early care, as well as revascularisation treatments (AU)

Relationship between serum levels of VIP, but not of CGRP, and cranial autonomic parasympathetic symptoms: A study in chronic migraine patients.

Background Cranial autonomic parasympathetic symptoms (CAPS) appear in at least half of migraine patients theoretically as a result of the release of peptides by the trigemino-vascular system (TVS). Cranial pain pathways become sensitised by repeated episodes of TVS activation, leading to migraine chronification. Objective The objective of this article is to correlate the presence of CAPS with serum levels of vasoactive intestinal peptides (VIP) and calcitonin gene-related peptide (CGRP). Patients and methods Patients with chronic migraine (CM) were asked about the presence - during migraine attacks - of five CAPS, which were scored from 0 to 10 by using a quantitative scale. Serum VIP and CGRP levels were determined by ELISA. Results We interviewed 87 CM patients (82 females; mean age 44.7 ± 10.6 years). Seventeen had no CAPS, while 70 reported at least one CAPS. VIP levels ranged from 20.8 to 668.2 pg/ml (mean 154.5 ± 123.2). There was a significant positive correlation between scores in the CAPS scale and VIP levels (Spearman correlation coefficient = 0.227; p = 0.035). VIP levels were significantly higher in CM patients by at least one point in the scale vs those with 0 points ( p = 0.002). Analysing symptoms individually, VIP levels were numerically higher in those patients with symptoms, though they were significantly higher only in those patients with lacrimation vs those without it ( p = 0.013). There was no significant correlation between CGRP levels and the score in the CAPS scale. Conclusions Serum VIP, but not CGRP, levels seem to reflect the rate of activation of the parasympathetic arm of the TVS in migraine.

[Description of a series of hospital patients with a spinal fistula]. / Descripcion de una serie hospitalaria de pacientes con fistula espinal.

INTRODUCTION: Although spinal fistulas account for 70% of all spinal arteriovenous malformations, they are an underdiagnosed condition. The arteriovenous shunt produces vascular congestion that gives rise to a progressive myelopathy, sometimes irreversible if it is not treated in the early stages. AIM: To describe the clinicoradiological characteristics of a series of patients with spinal fistulas. PATIENTS AND METHODS: A retrospective search was conducted for patients diagnosed with a spinal fistula who were hospitalised in the neuroscience area of a tertiary care hospital. RESULTS: A total of 19 patients (7 females and 12 males) were identified, with a mean age of 56 years. The spinal fistula was type I in 79% of patients, and a dorsal location was the most frequent. Most of the cases (90%) presented a progressive course. Magnetic resonance imaging was used in the diagnosis in 74% of the patients. In four cases angiography was required to reach a diagnosis, and in one of them it was necessary to perform an intraoperative biopsy. Three lumbar punctures were performed, two of which revealed lymphocytic pleocytosis and high protein levels in cerebrospinal fluid. The average diagnostic delay was nine months. Seventy-nine per cent of the patients were treated and only 10% of them improved. CONCLUSIONS: When faced with a clinical picture suggestive of a spinal fistula, a diagnostic spinal angiography must be carried out, although the patient under study may present atypical cerebrospinal fluid characteristics and normal results in magnetic resonance imaging of the spinal cord.

TITLE: Descripcion de una serie hospitalaria de pacientes con fistula espinal.Introduccion. Aunque las fistulas espinales suponen el 70% de las malformaciones arteriovenosas espinales, son una entidad infradiagnosticada. El shunt arteriovenoso produce una congestion vascular que da lugar a una mielopatia progresiva, en ocasiones irreversible si no se trata de forma precoz. Objetivo. Describir las caracteristicas clinicorradiologicas de una serie de pacientes con fistula espinal. Pacientes y metodos. Se realizo una busqueda retrospectiva de pacientes con diagnostico de fistula espinal ingresados en el area de neurociencias de un hospital de tercer nivel asistencial. Resultados. Se identificaron 19 pacientes (7 mujeres y 12 varones) con una edad media de 56 años. La fistula espinal fue de tipo I en un 79% de los pacientes y la localizacion dorsal fue la mas frecuente. La mayoria de los casos presento un curso progresivo (90%). Un 74% de los pacientes se diagnostico mediante resonancia magnetica. En cuatro casos fue necesaria la realizacion de una angiografia para llegar al diagnostico, y en uno de ellos se preciso una biopsia intraoperatoria. Se realizaron tres punciones lumbares, en dos de las cuales se objetivo pleocitosis linfocitaria e hiperproteinorraquia. El retraso diagnostico medio fue de nueve meses. Se trato a un 79% de los pacientes, y de ellos solo mejoro el 10%. Conclusiones. Ante una clinica sugestiva de fistula espinal, debe realizarse una angiografia espinal diagnostica aunque el paciente estudiado pueda presentar caracteristicas licuorales atipicas y normalidad en la resonancia magnetica medular.

Características sociodemográficas de una cohorte de pacientes con migraña crónica en un área sanitaria de Asturias / Sociodemographic characteristics of a cohort of patients with chronic migraine from a health district in Asturias

Introducción: La migraña crónica (MC) con o sin abuso de fármacos es una patología frecuente en la población general. Tradicionalmente se ha asumido que presentarla conlleva un detrimento del nivel socio-laboral y educacional. Nuestro objetivo ha sido analizar descriptivamente estas características en una cohorte de pacientes con MC y compararlas con las de nuestra población. Material y métodos: Analizamos, mediante una entrevista telefónica y una encuesta diseñada ad hoc, las características sociodemográficas de 150 pacientes diagnosticados de MC en nuestra consulta de cefaleas según los criterios de la Clasificación Internacional de Cefaleas. Los resultados se compararon con los obtenidos en la III Encuesta de Salud de Asturias llevada a cabo en el año 2012. Resultados: De los 150 pacientes, 142 (95%) eran mujeres. El 59,3% de los pacientes entrevistados estaban casados, 22% solteros, 12,6% divorciados y 6% eran viudos. Con respecto al nivel educacional encontramos que un 73% de nuestros pacientes habían cursado estudios secundarios o superiores frente a un 25% que habían cursado solo estudios primarios. Un 60% de los pacientes está activo laboralmente, mientras que el resto se encuentra inactivo. En global, estas cifras no difieren de las arrojadas por la III Encuesta de Salud de Asturias. Discusión: La idea clásica de que la MC causa un deterioro en la situación laboral, personal y educacional de los pacientes que la presentan no se confirma en nuestra serie, en la que la mayoría de pacientes con MC tienen un nivel educacional medio-alto y una buena situación socio-laboral. Es posible que estos resultados se deban a que nuestra serie comprende solo a pacientes con MC que acuden a una consulta especializada y, por tanto, no sean necesariamente aplicables al global de pacientes con MC

Introduction: Chronic migraine (CM), with or without medication overuse, is a common condition in the general population. It has traditionally been assumed that suffering CM has an impact on a patient's socio-occupational and educational level. Our goal was to analyse these characteristics in a cohort of patients with CM and compare them to the general population. Material and methods: We used a telephone interview and an ad hoc questionnaire to record and analyse the sociodemographic characteristics of 150 patients with a diagnosis of CM according to the criteria of the International Headache Classification. Results were compared to those obtained by the Third Health Survey of Asturias, conducted in 2012. Results: Of the 150 patients, 142 were women (95%). Married patients accounted for 59.3% of the total interviewees, while 22% were single, 12.6% divorced, and 6% were widowed. Regarding educational level, we found that 73% of our patients had completed secondary or higher education and 25% had completed only primary education. Sixty per cent of these patients are occupationally active, while the rest are not actively employed. Overall, these figures do not differ from those published by the Third Health Survey of Asturias. Discussion: The classic idea that CM has a negative impact on patients’ educational, personal, and occupational situations was not confirmed in our series. In fact, most patients with CM reported a medium-high educational level and a good socio-occupational status. However, since our series includes only CM patients attended in a specialist clinic, our results are not necessarily applicable to all patients with CM

Successful treatment of Old World cutaneous leishmaniasis caused by Leishmania infantum with posaconazole.

Old World cutaneous leishmaniasis is a widespread and potentially disfiguring protozoal infection that is endemic in the Mediterranean basin, Africa, and parts of Asia. Human infection is caused by several species of Leishmania parasites, such as Leishmania infantum. Available systemic and topical treatments vary in efficacy and are often unjustified due to their toxicity. We report on a case that was treated with posaconazole, a drug typically considered an antifungal agent but which also targets specific metabolic pathways of the parasite.

Amiodarone and itraconazole: a rational therapeutic approach for the treatment of chronic Chagas' disease.

In the Americas, approximately 20 million people suffer from the chronic phases of Chagas' disease, of which chagasic cardiomyopathy is the most important clinical feature. The elimination of Trypanosoma cruzi is a pivotal step in arresting the evolution of the disease. Unfortunately, currently available chemotherapy is mostly ineffective due to its limited efficacy and toxic side effects. The following case highlights the efficacy of new diagnostic and follow-up methods in the evaluation of novel trypanocidal compounds such as amiodarone and itraconazole.

Extensive chromoblastomycosis caused by Fonsecaea pedrosoi successfully treated with a combination of amphotericin B and itraconazole.

Chromoblastomycosis is a chronic infection caused by dematiaceous (dark-colored) fungi which affect the skin and subcutaneous tissues, and is characterized by a wide variety of clinical and dermatological features including papillomatous, verrucous and vegetating lesions. Although it has been described world-wide, most cases originate in tropical and sub-tropical areas. In general, present treatments of the disease are unsatisfactory as one of the most common etiologic agents, Fonsecaea pedrosoi is difficult to manage from a therapeutic point of view. We report a case of extensive chromoblastomycosis of 22 years duration caused by F. pedrosoi and review the clinical course, diagnosis and management of this disease.
