RESUMO

Introducción: La inflamación relacionada con la angiopatía amiloide es una entidad caracterizada por una respuesta inflamatoria alrededor de los depósitos de beta amiloide de la microcirculación cerebral. Métodos: Revisión retrospectiva de una serie de pacientes con inflamación relacionada con angiopatía amiloide, que cumplieran criterios clínico-radiológicos o con diagnóstico histopatológico confirmado. Resultados: Se incluyeron siete pacientes, cinco varones, con edad media de 79 años. El inicio fue agudo o subagudo en seis de los casos. La clínica más frecuente fue deterioro cognitivo (n = 6), alteraciones de conducta (n = 5), crisis epilépticas (n = 5), focalidad neurológica (n = 4) y cefalea (n = 2). El líquido cefalorraquídeo fue anormal en tres de cinco casos (pleocitosis linfocitaria e hiperproteinorraquia). Las imágenes de resonancia magnética cerebral más frecuentes consistieron en microhemorragias (n = 7), hiperintensidades subcorticales en secuencia T2-FLAIR (n = 7) y realce leptomeníngeo (n = 6). La afectación fue bilateral en tres de los casos, con predominio en regiones parieto-occipitales (n = 5). Se realizó una tomografía por emisión de positrones (PET) de amiloide en dos pacientes, resultando positiva en uno. Se obtuvo la confirmación histopatológica mediante una biopsia en dos de los casos. Todos los sujetos recibieron tratamiento inmunosupresor, objetivándose una respuesta clínica y radiológica inicial favorable, con recaída radiológica en dos de los casos tras la retirada del tratamiento, y mejorando tras la reinstauración. Conclusiones: El diagnóstico resulta imprescindible de cara a iniciar un tratamiento precoz, ya que ha demostrado mejorar el pronóstico y disminuir las recurrencias. Si bien el diagnóstico definitivo es histopatológico, los criterios clínico-radiológicos permiten el diagnóstico de esta entidad sin necesidad de biopsia.(AU)


Introduction: Cerebral amyloid angiopathy–related inflammation (CAA-ri) is an entity characterised by an inflammatory response to β-amyloid deposition in the walls of cerebral microvessels. Methods: We conducted a retrospective review of a series of patients with a diagnosis of CAA-ri according to histopathological study findings or clinical-radiological diagnostic criteria. Results: The study included 7 patients (5 men) with a mean age of 79 years. Disease onset was acute or subacute in 6 patients. The most frequent symptoms were cognitive impairment (n = 6), behavioural alterations (n = 5), epileptic seizures (n = 5), focal neurological signs (n = 4), and headache (n = 2). Cerebrospinal fluid was abnormal in 3 patients (lymphocytic pleocytosis and high protein levels). The most frequent MRI findings were microbleeds (n = 7), subcortical white matter hyperintensities on T2-FLAIR sequences (n = 7), and leptomeningeal enhancement (n = 6). Lesions were bilateral in 3 patients and most frequently involved the parieto-occipital region (n = 5). Amyloid PET studies were performed in 2 patients, one of whom showed pathological findings. Two patients underwent brain biopsy, which confirmed diagnosis. All patients received immunosuppressive therapy. An initially favourable clinical-radiological response was observed in all cases, with 2 patients presenting radiological recurrence after treatment withdrawal, with a subsequent improvement after treatment was resumed. Conclusions: Early diagnosis of CAA-ri is essential: early treatment has been shown to improve prognosis and reduce the risk of recurrence. Although a histopathological study is needed to confirm diagnosis, clinical-radiological criteria enable diagnosis without biopsy.(AU)

RESUMO

Cardiovascular risk (CVR) estimation is a fundamental tool for guiding therapy. Albuminuria indicates target organ damage in an accessible, economic and non-invasive manner. Improves high-risk patient identification, especially in chronic kidney disease (CKD) and diabetes mellitus (DM). In addition, anti-albuminuric treatments may improve CVR. This would position albuminuria as a guide and therapeutic objective. Although the capacity of albuminuria as an epidemiological CVR marker in specific populations (hypertension, CKD, DM) is accepted, its profile as a risk marker in the general population and as a therapeutic target is controversial. There is ambiguous evidence regarding its predictive capacity, added to the fact that treatments such as SLGT2 blockers reduce CVR events regardless of albuminuria presence or magnitude. This review analyzes the available evidence on albuminuria as a CVR marker, a treatment goal and therapeutic guide.

La estimación de riesgo cardiovascular (RCV) es una herramienta fundamental para dirigir la terapéutica. Albuminuria indica daño en órgano blanco de manera accesible, económica y no invasiva. Mejora la identificación de pacientes de alto riesgo, especialmente en enfermedad renal crónica (ERC) y diabetes mellitus (DM). Además, tratamientos antialbuminúricos mejorarían el RCV y la ocurrencia de eventos. Esto posicionaría a la albuminuria como guía y objetivo terapéutico. Si bien la capacidad de albuminuria como marcador epidemiológico de RCV en poblaciones específicas es aceptado, su perfil de marcador de riesgo en población general y como objetivo terapéutico es controvertido. Existe evidencia contrapuesta respecto a su capacidad de predicción, sumado a que tratamientos como los bloqueadores SGLT2 reducen eventos CV independientemente de la presencia y/o magnitud de albuminuria. En esta revisión se analiza la evidencia disponible sobre albuminuria como marcador de RCV, como objetivo de tratamiento y como guía terapéutica. (AU)

RESUMO

INTRODUCTION: Cerebral amyloid angiopathy-related inflammation (CAA-ri) is an entity characterised by an inflammatory response to ß-amyloid deposition in the walls of cerebral microvessels. METHODS: We conducted a retrospective review of a series of patients with a diagnosis of CAA-ri according to histopathological study findings or clinical-radiological diagnostic criteria. RESULTS: The study included 7 patients (5 men) with a mean age of 79 years. Disease onset was acute or subacute in 6 patients. The most frequent symptoms were cognitive impairment (n = 6), behavioural alterations (n = 5), epileptic seizures (n = 5), focal neurological signs (n = 4), and headache (n = 2). Cerebrospinal fluid was abnormal in 3 patients (lymphocytic pleocytosis and high protein levels). The most frequent MRI findings were microbleeds (n = 7), subcortical white matter hyperintensities on T2-FLAIR sequences (n = 7), and leptomeningeal enhancement (n = 6). Lesions were bilateral in 3 patients and most frequently involved the parieto-occipital region (n = 5). Amyloid PET studies were performed in 2 patients, one of whom showed pathological findings. Two patients underwent brain biopsy, which confirmed diagnosis. All patients received immunosuppressive therapy.

RESUMO

INTRODUCTION: To date, few studies have explored the specific risk factors of patients with listeriosis who develop rhombencephalitis, and there is insufficient information regarding imaging findings and clinical symptoms in patients with this disease. This work aimed to analyze the imaging findings associated with L. monocytogenes rhombencephalitis in a cohort of patients with listeriosis. MATERIALS AND METHODS: We conducted a retrospective observational study of all declared cases of listeriosis in a tertiary hospital from Granada, Spain, from 2008 to 2021. Risk factors, comorbidities, and clinical outcomes were collected for all patients. In addition, clinical symptoms and magnetic resonance imaging (MRI) findings were included for those patients who developed rhombencephalitis. Descriptive and bivariate analyses were performed using SPSS statistical software (IBM SPSS, version 21). RESULTS: Our cohort comprised 120 patients with listeriosis (41.7% women, mean age: 58.6 ± 23.8 years), of which 10 (8.3%) had rhombencephalitis. The most frequent MRI findings in patients with confirmed rhombencephalitis were T2-FLAIR hyperintensity (100%), T1 hypointensity (80%), scattered parenchymal enhancement (80%), and cranial nerve enhancement (70%), while the most frequent anatomical involvement were pons, medulla oblongata, and cerebellum. Complications occurred in 6 patients (abscess in 4, hemorrhage in 2, hydrocephalus in 1). CONCLUSIONS: Rhombencephalitis is associated with an increased in-hospital mortality in patients with listeriosis. The anatomical distribution and imaging characteristics of neurolisteriosis could be useful to suggest the diagnosis. Future studies with greater sample size should explore the association between anatomical location, imaging patterns, and associated complications (e.g., hydrocephalus, hemorrhage), and clinical outcomes.

Se produjeron complicaciones en seis pacientes (absceso en cuatro, hemorragia en dos e hidrocefalia en uno). Conclusiones. La rombencefalitis se asocia a un aumento de la mortalidad intrahospitalaria en pacientes con listeriosis. La distribución anatómica y las características de imagen de la neurolisteriosis podrían ser útiles para sugerir el diagnóstico. Futuros estudios con mayor tamaño muestral deberían explorar la asociación entre la localización anatómica, los patrones de imagen y las complicaciones asociadas (por ejemplo, hidrocefalia y hemorragia), y los resultados clínicos.

RESUMO

There is a lack of studies assessing whether wide excision surgery in hidradenitis suppurativa affected areas is useful for the global control of the hidradenitis suppurativa. We aimed to find whether surgery results were a better global control on the disease activity in both, the area where the surgery is performed and distant areas. We evaluated the disease course of 17 patients with hidradenitis suppurativa who underwent wide excision of complex fistula tracts between October 2018 and January 2022 at the Hospital Universitario de la Princesa, Madrid. We found that wide excision of complex fistulas produces an overall positive effect on the inflammatory activity in hidradenitis suppurativa that may be important to achieve an adequate control of the disease (AU)

RESUMO

Heavy metals (HMs) and metalloids (Ms) such as arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) represent serious environmental threats due to their wide abundance and high toxicity. Contamination of water and soils by HMs and Ms from natural or anthropogenic sources is of great concern in agricultural production due to their toxic effects on plants, adversely affecting food safety and plant growth. The uptake of HMs and Ms by Phaseolus vulgaris L. plants depends on several factors including soil properties such as pH, phosphate, and organic matter. High concentrations of HMs and Ms could be toxic to plants due to the increased generation of reactive oxygen species (ROS) such as (O2•-), (•OH), (H2O2), and (1O2), and oxidative stress due to an imbalance between ROS generation and antioxidant enzyme activity. To minimize the effects of ROS, plants have developed a complex defense mechanism based on the activity of antioxidant enzymes such as SOD, CAT, GPX, and phytohormones, especially salicylic acid (SA) that can reduce the toxicity of HMs and Ms. This review focuses on evaluating the accumulation and translocation of As, Cd, Hg, and Pb in Phaseolus vulgaris L. plants and on their possible effects on the growth of Phaseolus vulgaris L. in soil contaminated with these elements. The factors that affect the uptake of HMs and Ms by bean plants, and the defense mechanisms under oxidative stress caused by the presence of As, Cd, Hg, and Pb are also discussed. Furthermore, future research on mitigating HMs and Ms toxicity in Phaseolus vulgaris L. plants is highlighted.
