Retinal Thickness and Microvascular Pattern in Early Parkinson's Disease.

2020

A thinning of intraretinal layers has been previously described in Parkinson's disease (PD) patients compared to healthy controls (HCs). Few studies evaluated the possible correlation between retinal thickness and retinal microvascularization. Thus, here we assessed the thickness of retinal layers and microvascular pattern in early PD patients and HCs, using, respectively, spectral-domain optical coherence tomography (SD-OCT) and SD-OCT-angiography (SD-OCT-A), and more interestingly, we evaluated a possible correlation between retinal thickness and microvascular pattern. Patients fulfilling criteria for clinically established/clinically probable PD and HCs were enrolled. Exclusion criteria …

Efecto de la radiación ionizante persistente a bajas dosis en la angiogénesis del carcinoma renal de células claras : estudio morfométrico comparativ…

2013

La angiogénesis en el carcinoma de células renales claras (ccRCC) es un proceso influenciado por sustancias producidas en su mayoría por el tumor en respuesta a una reestructuración vascular necesaria en su etapa de crecimiento y metástasis. La exposición persistente a bajas dosis de radiación ionizante (CPLDIR) ha sido asociada a modificaciones nucleares que estimulan la proliferación celular neoplásica. Sus efectos en el proceso de neovascularización de los ccRCC han sido poco estudiados. Métodos: Estudiamos a través de un estudio morfométrico semiautomático e inmunohistoquímico, la densidad microvascular (MVD) y la expresión de factores angiogénicos en 124 pacientes con ccRCC de regiones…

Clinical characteristics of oral chronic graft-versus-host disease according to the 2014 National Institutes of Health (USA) consensus criteria.

2022

Chronic graft-versus-host disease (cGVHD) is a serious and common complication of allogeneic hematopoietic cell transplantation (alloHCT). The oral cavity is the second most common site affected by cGVHD. In 2014, the 2005 National Institutes of Health (NIH) consensus criteria were revised to address areas of controversy. The aim of this study was to evaluate the clinical characteristics of oral cGVHD using the 2014 NIH consensus criteria. The baseline data of oral manifestation of patients, who were diagnosed with oral cGVHD, in the first dental visit were analyzed (n=22). The oral mucosal disease was evaluated by NIH modified Oral Mucosa Rating Scale (OMRS) and Thongprasom sign score. The…
