TSH reference values in the first trimester of gestation and correlation between maternal TSH and obstetric and neonatal outcomes: a prospective Brazilian study

ABSTRACT Objective To define the normal range of TSH in the first trimester of gestation and to evaluate the correlation between maternal TSH and obstetric and neonatal outcomes. Subjects and methods Prospective study. Women without known or clinically suspected thyroid disease and without risk facto...

Mean platelet volume in patients with prolactinoma

ABSTRACT Objective Prolactin is a multifunctional pituitary hormone. The effect of prolactin on platelet activation is not well understood. Prolactinomas are the most common type of pituitary adenomas, and they are medically responsive to dopamine agonists. Mean platelet volume (MPV) is a marker of pla...

Dynamic changes in optic disc morphology, choroidal thickness, anterior chamber parameters, and intraocular pressure during Valsalva maneuver

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT Purpose: To investigate the effects of the Valsalva maneuver (VM) on optic disc morphology, choroidal thickness, and anterior chamber parameters. Methods: This prospective observational study included 60 eyes of 60 healthy subjects. The anterior chamber parameters, including central corneal th...

Differentiation of mild keratoconus from corneal warpage according to topographic inferior steepening based on corneal tomography data

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT We report two cases of suspicious asymmetric bow tie and inferior steepening on topographic evaluations with reflection (Placido) and projection (Scheimpflug). Rotating Scheimpflug corneal and anterior segment tomography (Oculus Pentacam HR, Wetzlar, Germany)® was performed in the first case, w...

Evaluation of choroidal and retinal thickness measurements in adult hemodialysis patients using spectral-domain optical coherence tomography

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT Purpose: To assess the effect of hemodialysis on retinal and choroidal thicknesses using spectral-domain optical coherence tomography (SD-OCT). Methods: In this prospective interventional study, 25 hemodialysis patients (17 male, 8 female) were enrolled. All participants underwent high-speed, ...

Short-term effects of intravitreal dexamethasone implant (OZURDEX®) on choroidal thickness in patients with naive branch retinal vein occlusion

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT Purpose: The objective of this study was to evaluate subfoveal choroidal thickness (SFCT) using enhanced depth imaging optical coherence tomography (EDI-OCT) in patients with naïve branch retinal vein occlusion (BRVO) before and after intravitreal dexamethasone implant (Ozurdex®) injection. ...

Oxidative stress of crystalline lens in rat menopausal model

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT Purpose: To evaluate lenticular oxidative stress in rat menopausal models. Methods: Forty Wistar female albino rats were included in this study. A total of thirty rats underwent oophorectomy to generate a menopausal model. Ten rats that did not undergo oophorectomy formed the control group (Gr...

Economic evaluation of the new oral anticoagulants for the prevention of thromboembolic events: a cost-minimization analysis

Säo Paulo med. j; 134 (4), 2016
ABSTRACT CONTEXT AND OBJECTIVE: Randomized clinical trials have shown that the new oral anticoagulants have at least similar impact regarding reduction of thromboembolic events, compared with warfarin, with similar or improved safety profiles. There is little data on real costs within clinical practice...
