OBJECTIVE To describe an outbreak of mycobacterial keratitis after laser in situ keratomileusis (LASIK), including the microbiologic investigation, clinical findings, treatment response, and outcome. DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Patients (n = 10) who underwent LASIK surgery between August 22 and(More)
We investigated the effect of low temperature and urea combined with high pressure on tobacco mosaic virus (TMV). The evaluation of its aggregation state and denaturation process was studied using gel filtration, transmission electron microscopy, and spectroscopic methods. The incubation at 2.5 kbar induced 18% dissociation, and decreasing of temperature to(More)
PURPOSE To report three cases of infectious crystalline keratopathy caused by non-tuberculous mycobacteria after LASIK surgery. METHODS Interventional case reports and literature review. RESULTS Infectious keratitis with clinical features of crystalline keratopathy after LASIK is described. Culture revealed Mycobacterium chelonae from the corneal(More)
AIM The present study aims (1) to provide reference percentile charts for the following measures of Physical Fitness (PF): the sit-and-reach, handgrip, standing long jump, 50 yards' dash, 4x10m shuttle run and 1-mile run/walk tests in children aged 6 to 10 years, and (2) to compare the performance of the Portuguese children with their age- and sex peers.

PURPOSE The purpose of this study was to analyze the cutaneous sensitivity to a variety of allergens in patients with vernal keratoconjunctivitis (VKC) and to demonstrate the relation between skin response and clinical aspects of the disease. METHODS Twenty patients with vernal keratoconjunctivitis were randomly chosen from the External Disease and Cornea(More)
Chlorophenylpiperazines (CPP) are psychotropic drugs used in nightclub parties and are frequently used in a state of sleep deprivation, a condition which can potentiate the effects of psychoactive drugs. This study aimed to investigate the effects of sleep deprivation and sleep rebound (RB) on anxiety-like measures in mCPP-treated mice using the open field(More)
PURPOSE To evaluate the efficacy and the toxicity of 0.15% ganciclovir gel in the treatment of adenoviral conjunctivitis and in preventing ocular complications after adenoviral conjunctivitis, such as corneal infiltrates and pseudomembranes. METHODS Double blind, interventional and randomized clinical trial. Thirty-three patients with clinical diagnosis(More)
OBJECTIVE To assess the usefulness of corneal esthesiometry for screening diabetic retinopathy. METHODS A cross-sectional study was carried out comprising 575 patients attending a diabetic retinopathy-screening program in the city of São Paulo. Corneal esthesiometry was assessed with the Cochet-Bonnet esthesiometer. The presence of diabetic retinopathy(More)
Proteolytic enzymes secreted by trophozoites (amoebic secretome) are suggested as the main virulence factor involved in the severity of Acanthamoeba keratitis. The degradation profile of the main glycoprotein components of anterior and posterior portions of the cornea and the cytopathic effect of secretomes on endothelial cells by contact-independent(More)
PURPOSE To analyze the frequency and the etiology of mycotic infectious eye diseases diagnosed by culture at the Ocular Diseases Laboratory of the Federal University of São Paulo (LOFT-UNIFESP), São Paulo, SP, Brazil, and the factors associated with fungal keratitis. METHODS We retrospectively analyzed the 14,391 laboratory requests regarding infectious(More)
