Las enfermedades pulmonares intersticiales difusas constituyen un grupo heterogéneo de afecciones poco frecuentes del parénquima pulmonar (alvéolo, intersticio, pequeñas vías aéreas y vasos) e interfieren en el intercambio gaseoso.

CLINICAL CHARACTERISTICS IDENTIFYING BRAIN ATROPHY IN OLDER PATIENTS WITH BIPOLAR DISORDER
Clinical characteristics that may identify bipolar patients at high risk for developing brain atrophy in late life remain undiscovered. Forty-four bipolar I patients aged beyond 60 years were recruited in this study. Thirty-three of them had brain atrophy on structural magnetic resonance imaging at 1.5 T. The positive history of rapid cycling and lower hemoglobin levels during affective episodes provided the greatest predictive validity for brain atrophy.

  DIFFERENTIAL DIAGNOSIS OF LUNG CARCINOMA WITH LABEL-FREE IMAGING
This report describes a new class of endomicroscopy that combines chemical selective molecular vibrational imaging techniques, such as coherent anti-Stokes Raman scattering (CARS) imaging, with fiber optic delivery and quantitative analytics for obtaining histology-like images from inside the human body in real-time with no label. Endomicroscopes generally can achieve a resolution on the order of a µm and have a field-of-view of several hundred µm. Current endomicroscope products, however, often require fluorophores, which are excitable using laser lights, and limit their applications in clinics. The objective of the proposed label-free endomicroscope is to sidestep the use of flourophores by visualizing morphological patterns and detecting intrinsic biomarkers of cells and tissues via high-speed, chemical selective CARS imaging. The label-free endomicroscope is developed to post-process and characterize CARS images and provide diagnostic information using disease-related features and classification. The prototype device has shown high accuracy and specificity for differential lung cancer diagnosis and thus demonstrated its potential for clinical translations.

MULTIFOCAL-VEP, VEP, AND FDT PERIMETRY IN OPTIC NEURITIS Artículos relacionados
The clinical work-up and follow-up of optic neuritis patients should include firstly the conventional visual evoked potentials (VEP) and automated perimetry that are readily available in most centers. Multifocal-VEP may be added in those cases with early optic neuritis or with doubtful or negative test results on the previous tests.
