Methods This prospective, double-masked, randomized, placebo-controlled included 40 subjects divided into 2 treatment groups: group 1 (2% polyvinylpyrrolidone placebo) 0.1% butyrate, drop BID). The lasted for 30 days, visits at enrollment, baseline, day 15, 30, after 15 days discontinuation. At each visit, symptoms questionnaire, tear film...

The most common cause of the development odontogenic infection is untreated dental caries, which initially leads to pulpitis. If an left untreated, it will pass through limiting bone plate and infiltrate deeper structures. Odontogenic infections are different in adults children. study was conducted at Department Pediatric Otolaryngology Head Neck Surgery Upper Silesian Children’s Health Center Katowice 2020–2022. We included 27 patients aged 2–16 study. Patients were diagnosed with active,...

Polymethylmethacrylate (PMMA) has been irradiated by 365 nm UV wavelength at different exposition times in air and room temperature. The macromolecular modifications induced the polymer have investigated using attenuated total reflectance (ATR) coupled to Fourier transform infrared (FTIR) spectroscopy, UV-Visible surface profiler, wetting ability, electronic microscopy. observed chemical, optical morphological changes occurred as a consequence of irradiation suggest that chain scissions are...

To evaluate the effect of basic fibroblast growth factor (bFGF) eye drops on corneal epithelial healing after photorefractive keratectomy (PRK).One hundred patients treated with PRK for myopia were enrolled in this prospective, randomized study. Fifty postoperatively standard topical therapy and bFGF 50 patients, used as controls, received postoperative plus placebo (saline drops). Postoperatively, examined daily until epithelium healed. The velocity resurfacing was recorded. Corneal...

To investigate the ultrastructure of advanced Salzmann nodular degeneration (SND) and to correlate it confocal in vivo findings.The corneal degenerative nodules from four patients with SND were examined microscopy then removed processed for light (LM) transmission electron (TEM).The examination revealed elongated basal epithelial cells activated keratocytes anterior stroma near nodules. Occasional subbasal nerves tortuous stromal nerve bundles observed. With LM TEM, five zones described: one...

The pecten oculi is a highly vascular and pigmented organ placed in the vitreous body of avian eye. As no data are currently available on morphological organization Psittaciformes, budgerigar (Melopsittacus undulatus) was studied. eyes from adult male budgerigars were examined by light, transmission, scanning electron microscopy morphometric study both light transmission specimens also performed different parts organ. In budgerigar, type pleated. Its basal part had cranio-caudal...

Purpose: To evaluate the effect of aminoacid enriched artificial tears on ocular surface patients with dysfunctional tear syndrome (DTS). Methods: Forty were divided into two groups: group 1 treated for 90 days sodium hyaluronate (SH) 0.15% drop × 5 times/day; 2 SH + aminoacids mixture times/day. Symptom score questionnaire, break-up time (TBUT), corneal fluorescein stain, Shirmer's I test and confocal microscopy performed at baseline after 30 days. Confocal images underwent morphometric...

Purpose: The aim of this study was to analyze the corneal morphology features and define mutations in UbiA prenyltransferase domain–containing 1 (UBIAD1) gene patients with Schnyder dystrophy from a Polish population. Methods: Five affected 15 unaffected members originating 3 families were included study. Phenotype analysis consisted visual acuity, slit-lamp biomicroscopy photography, time domain optical coherence tomography, spectral confocal microscopy. Three underwent penetrating...

The purpose of this study was to analyze corneal sub-basal nerve plexus (SBNP) density and morphology their relationships with parameters refractive status. In single center study, in vivo confocal microscopy (IVCM) performed 76 eyes 38 healthy subjects aged 19-87 (mean age 34.987 ± 1.148). Nerve fiber analysis using Confoscan 4 microscope semi-automated software (Nidek Technologies, Italy) length (NFL) µm/mm2, (NFD) no./mm2, tortuosity coefficient (TC), beadings (NBD) no./mm were...

Background: Philadelphia-negative chronic myeloproliferative neoplasms are a group of clonal hematopoietic disorders including polycythemia vera, essential thrombocythemia, and primary myelofi-brosis. These characterized by an increased risk thrombotic complications. Several studies have highlighted that the study vessels retina offers opportunity to visualize, in vivo, damage microcirculation is common various systemic pathologies. Methods: our study, forty patients underwent...

Abstract Intraocular lens (IOL) made on Polymethylmethacrylate (PMMA) has been irradiated by a UV lamp at different exposure times, in air and room temperature. The macromolecular modifications induced the have investigated using attenuated total reflectance (ATR) coupled to Fourier transform infrared (FT-IR) spectroscopy Optical spectroscopy. Particular attention was devoted study of chemical irradiation, which chain scissions superficial PMMA layers. Results demonstrated that transmission...
