title: Indications for eye removal over a 13-year period at an ophthalmology referral center in São Paulo, Brazil

description: ABSTRACT Purpose: To analyze the indications and types of eye removal at Latin America's highest-volume ophthalmic reference center in São Paulo, Brazil. Methods: A retrospective analysis was conducted of surgical pathological reports in the electronic database of the Ophthalmology Department of the Universidade Federal de São Paulo Hospital of patients who underwent eye-removal procedures between January 2000 and December 2012. Results: A total of 412 cases met the inclusion criteria for this study. The most common indications for eye removal were ocular melanoma and retinoblastoma, representing 35.4% and 31.1% of the total cases, respectively. Other frequent indications included endophthalmitis (6.3%), nonspecific inflammation (4.1%), squamous cell carcinoma (3.6%), panophthalmitis (3.4%), and phthisis bulbi (1.2%). The remaining indications accounted for 14.8% of all cases, with each accounting for &lt;1% of the total cases. Enucleation was the most common eye-removal procedure seen in our study. Conclusions: The two most common indications for eye removal were ocular melanoma and retinoblastoma. Alternative treatment options are effective in limiting the need for eye removal but are constrained by our public center's so cioeconomic context.

title: CARE FOR PEOPLE DEPRIVED OF FREEDOM WITH TUBERCULOSIS AND PERMANENT EDUCATION IN HEALTH

description: Abstract Tuberculosis is one of the main grievances to be combated throughout the world, and the high incidence among the population that is deprived of freedom (904.9/100 thousand inhabitants, in 2013) contributes to increase the dimension of the problem. This study presents the analysis based on action research, which was developed through an institutional intervention that used Ongoing Education in Health to reorganize the care provided to those deprived of freedom who have tuberculosis. The participants of the research were the nursing workers at a penitentiary in the state of Paraná, Brazil; the workers participated in seven Ongoing Education in Health workshops. Three of the workshops were on team work, user embracement and joint responsibility; two other workshops discussed the current aspects of the disease, the care practice developed, and a new work proposal was established by the team. The last two workshops monitored the implemented proposal and corrected mistakes. The action research combined with the Ongoing Education in Health was adequate regarding the development of the intervention, and enabled the change in the practices of the workers and the transformation of the care for people with tuberculosis in that institution.

title: Floral resins of Philodendron adamantinum (Araceae): secretion, release and synchrony with pollinators

description: ABSTRACT Philodendron is the only genus of Araceae in which resin release occurs in the inflorescence. The resinous secretion adheres to the smooth body surface of the pollinating scarab beetles and allows attachment of pollen grains, making its transport possible. In order to understand the process of resin synthesis and release to the external environment, we used structural, ultrastructural and histochemical analyses at different stages of development of the inflorescences of Philodendron adamantinum. Two types of secretory canals were observed in the spathe: small caliber canals near the abaxial face, and larger caliber canals in the adaxial region. Only the latter canals release secretion into the external environment. The secretory epithelium in these canals is formed by a layer of cuneiform cells, and exhibits secretory activity throughout the development of the spathe. Resin exudation is a peculiar characteristic of these canals and appears to result from pressure exerted by the secretory epithelium and by structural modifications in the wall of cells adjacent to the epidermis, which allow the formation of a separation zone whereby the resin is released. The observed synchrony between anther dehiscence and resin exudation of P. adamantinum enhances the role of this secretion in the pollination process.

title: Vitamin D level in patients with pterygium

description: ABSTRACT Purpose: To evaluate blood vitamin D level in patients with pterygium. Methods: This prospective study, compared 58 eyes of 58 healthy individuals (control group) with 63 eyes of 63 patients with pterygium (study group). Subjects were stratified by time spent indoors or outdoors. Participants were given comprehensive ophthalmic examinations; blood 25-hydroxyvitamin D (nmol/L) was assayed. Results: Vitamin D level was significantly higher in men with pterygium than without it (p=0.020), but the difference was not significant in women (p=0.86). In the pterygium group, vitamin D level was significantly increased in participants with outdoor activity (p=0.010). In the control group, vitamin D levels did not differ significantly with indoor and outdoor activity (p=0.126). Conclusion: Vitamin D level in participants with pterygium was significantly increased only in men and in those with more outdoor activity.

title: Prevalence and associated factors of external punctal stenosis among elderly patients in Turkey

description: ABSTRACT Purpose: To estimate the prevalence of external punctal stenosis (EPS) in the elderly population and investigate associated factors. Methods: A total of 278 patients ≥65 years of age were evaluated for evidence of EPS from January to July 2016. Associated systemic, ocular, demographic, and lifestyle factors were investigated. Multiple logistic regression analyses were applied to evaluate the factors related to having EPS. P values &lt;0.05 were considered statistically significant. Results: The prevalence of EPS in this study population was 63.3%, with a mean age of 70.67 ± 7.85 (65-92 years). The ocular factor that was most commonly related to EPS was chronic blepharitis (48.9%). EPS was also associated with taking glaucoma medications (95% CI, 0.08-0.96, p=0.043), smoking history (95% CI, 0.13-0.84, p=0.021), ectropion (95% CI, 0.004-0.26, p=0.001), complaints of tearing (95% CI, 1.11-3.52, p=0.02), and outdoor occupational activity (95% CI, 3.42-9.97, p&lt;0.05). Conclusions: EPS is more common in elderly patients than in the general population. Outdoor occupational activity, taking antiglaucomatous medications, ectropion, and smoking are significantly associated with EPS. In addition, surgical treatment decisions should be made after complete evaluation and interviewing the patients.

title: Unraveling algae and cyanobacteria biodiversity in bromeliad phytotelmata in different vegetation formations in Bahia State, Northeastern Brazil

description: ABSTRACT Knowledge of algal and cyanobacterial diversity of phytotelmata remains poorly-known, especially for bromeliads from different vegetation formations. We investigated the microalgae communities of four species of tank bromeliads from different vegetation formations in Bahia State, Northeast Brazil, highlighting the composition, richness and diversity of taxa. Sampling of water stored in bromeliads was carried out quarterly between 2014 and 2016, and abiotic variables and morphometric attributes of bromeliads were measured. A total of 89 taxa of algae and cyanobacteria were recorded for the four bromeliad species studied. The microalgae communities of the phytotelmata varied among vegetation formations, with one tank bromeliad, Alcantarea nahoumii, with more complex architecture (higher number of leaves and thus more cavities), being distinguished by its high species richness (73 taxa). The bromeliads exhibited little similarity in species composition, with only one species (Phacus polytrophos) occurring in all four species. Throughout the entire sampling period, classes with higher species richness, especially due to A. nahoumii, were Zygnematophyceae, Cyanophyceae and Chlorophyceae, which accounted for about 80 % of all species inventoried. Our results contribute to the knowledge of microalga communities of bromeliad phytotelmata in Brazil with regard to species richness and composition, as well as significant environmental characteristics.

title: Aqueous humor concentrations of topical fluoroquinolones alone or in combination with a steroid

description: ABSTRACT Purpose: To compare the aqueous humor (AH) concentrations of moxifloxacin 0.5% and gatifloxacin 0.3% solutions alone or when treatment was combined with steroids, and to correlate these concentrations with the minimum inhibitory concentrations (MIC) for the most common endophthalmitis-causing organisms. Methods: Patients undergoing phacoemulsification were enrolled to receive one drop of one of the following solutions: moxifloxacin (G1), moxifloxacin + dexamethasone (G2), gatifloxacin (G3), or gatifloxacin + c (G4), every 15 min, 1h before surgery. AH samples were collected before surgery and analyzed using HPLC-tandem mass spectrometry. Results: The mean antibiotic concentrations in the AH were: G1= 1280.8 ng/mL; G2= 1644.3 ng/mL; G3= 433.7 ng/mL; and G4= 308.1 ng/mL. The mean concentrations statistically differed between G1 and G2 (p=0.01), and G3 and G4 (p=0.008). All samples achieved the MIC for Staphylococcus epidermidis; 100% of the samples from G1 and G2, and 97% from G3 and G4 reached the MIC for fluoroquinolone-sensitive Staphylococcus aureus; 100% of the samples from G1 and G2, 88% from G3, and 72% from G4 reached the MIC for enterococci (p&lt;0.001); and 100% of samples from G1 and G2, 59% from G3, and 36% from G4 reached the MIC for Streptococcus pneumoniae (p&lt;0.001). For fluoroquinolone-resistant S. aureus, 23% from G1, 44% from G2, and no samples from G3 or G4 achieved the MIC (p&lt;0.001). Conclusions: Moxifloxacin + dexamethasone demonstrated a higher concentration in the AH than the moxifloxacin alone. Gatifloxacin + steroids demonstrated less penetration into the anterior chamber than gatifloxacin alone. Moxifloxacin was superior to gatifloxacin considering the MIC for enterococci, S. pneumoniae, and fluoroquinolone-resistant S. aureus.

title: Corneal biomechanical features in patients with ankylosing spondylitis

description: ABSTRACT Purpose: To evaluate the corneal biomechanical features and central corneal thickness in ankylosing spondylitis patients and to evaluate correlations of these parameters with disease activity. Methods: The study included 51 patients diagnosed with ankylosing spondylitis (mean age, 40.80 ± 13.15 years; range, 18-72 years) and 34 age- and sex-matched healthy controls (mean age, 42.00 ± 12.32 years; range, 18-60 years). All underwent a complete ophthalmological and physical examination, including visual acuity testing and biomicroscopic anterior and posterior segment examinations. Corneal hysteresis, corneal resistance factor, Goldmann-correlated intraocular pressure, and corneal compensated intraocular pressure were evaluated with an ocular response analyzer, and the central corneal thickness was measured with Sirius® corneal tomography. The Bath Ankylosing Spondylitis Disease Activity Index, Functional Index, and Metrology Index scores were recorded. Results: In the ankylosing spondylitis patients, the mean disease duration was 7.73 ± 6.05 (range, 1-30) years. There was no statistically significant difference between the patients and controls in the corneal biomechanical features. The Goldmann-correlated intraocular pressure and corneal compensated intraocular pressure both showed positive correlations with age (p=0.003 and p=0.001, respectively). There was a negative correlation between corneal hysteresis and disease duration (p=0.002), and between central corneal thickness and the Bath Ankylosing Spondylitis Metrology Index score (p=0.003). Conclusion: This study demonstrated a significant negative correlation between corneal hysteresis and disease duration in ankylosing spondylitis patients. Furthermore, the central corneal thickness value decreased with an increase in Bath Ankylosing Spondylitis Metrology Index score, which may result in an underestimate of intraocular pressure readings and thus an inaccurate risk assessment of glaucoma.
