abstract   backgrounds: pott's disease is a rare form of extrapulmonary tuberculosis, and   presents with several clinical patterns. delay in diagnosis and management may   cause serious complications. we conducted a retrospective study between 1991-   2006 to evaluate clinical presentation, radiologic and laboratory findings, and therapeutic   approaches to spinal tuberculosis.   methods:...

PURPOSE To describe the incidence of transient light-sensitivity syndrome (TLSS) after laser in situ keratomileusis (LASIK) with the femtosecond laser and to identify preventive strategies. SETTING Hospital NISA Virgen del Consuelo, Valencia, Spain. METHODS The first 765 eyes operated on with the 15 KHz femtosecond laser were prospectively analyzed for subjective complaints and clinical fin...

Exposure to constant light has a range of negative effects on behaviour and physiology, including reduced immune function in both vertebrates and invertebrates. It is proposed that the associated suppression of melatonin (a ubiquitous hormone and powerful antioxidant) in response to the presence of light at night could be an underlying mechanistic link driving the changes to immune function. He...

PURPOSE To compare the cost and effectiveness of three cycloplegic agents among Nigerian children. METHODS Two hundred thirty-three children aged 4 to 15 years attending outpatient eye clinics in Nigeria were randomized to (1) 1% cyclopentolate, (2) 1% cyclopentolate and 0.5% tropicamide, or (3) 1% atropine drops in each eye (instilled at home over 3 days). Ten children were lost to follow-up...

background: despite the effective pre- and post-exposure treatments, at least 60,000 deaths from rabies occur worldwide every year. post-exposure treatment is considered as one of the most significant measures for preventing human deaths in exposed individuals. the 2-1-1 rabies post-exposure treatment schedule known as zagreb regimen is an abbreviated immunization plan in which a tissue culture...

The use of platelet-rich plasma and growth factors is emerging as an anti-ageing regimen for the skin. We tested the safety and efficacy of 3D-MatrixLift®, a new treatment regimen for skin rejuvenation that combines medical needling and the application of a stem cell and growth factor-rich solution with irradiation by LED light. A total of 15 participants were enrolled in a single-centre, prosp...

Purpose The purpose of this study was to determine the effects of metformin on dysfunctional retinas in obesity-induced type 2 diabetic mice. Methods A high-fat diet (HFD)-induced diabetic mouse model (C57BL/6J) was used in this study. After 2 months of the HFD regimen, HFD mice were given daily metformin through oral gavage. Body weights, glucose tolerance, and retinal light responses were m...

The aim of this study was to assess polymerization ability of three light-curing units by evaluating the influence of the light source, curing regimen and permeant (water or ethanol) on sorption, solubility and amount of residual monomers of a dental adhesive. Specimens of Adper Single Bond 2 were fabricated using a stainless steel circular matrix (8 mm x 1 mm). One quartz-tungsten-halogen (QTH...
