title: Dysfunction in the fellow eyes of strabismic and anisometropic amblyopic children assessed by visually evoked potentials

description: ABSTRACT Purpose: To evaluate visual acuity and transient pattern reversal (PR) visual evoked potentials (VEPs) in the fellow eyes of children with strabismic and/or anisometropic amblyopia. Methods: Children diagnosed with strabismic and/or anisometropic amblyopia were recruited for electrophysiological assessment by VEPs. Monocular grating and optotype acuity were measured using sweep-VEPs and an Early Treatment Diabetic Retinopathy Study chart, respectively. During the same visit, transient PR-VEPs of each eye were recorded using stimuli subtending with a visual angle of 60', 15', and 7.5'. Parameters of amplitude (in μV) and latency (in ms) were determined from VEP recordings. Results: A group of 40 strabismic and/or anisometropic amblyopic children (22 females: 55%, mean age= 8.7 ± 2.2 years, median= 8 years) was examined. A control group of 19 healthy children (13 females: 68.4%, mean age= 8.2 ± 2.6 years, median= 8 years) was also included. The fellow eyes of all amblyopes had significantly worse optotype acuity (p=0.021) than the control group, regardless of whether they were strabismic (p=0.040) or anisometropic (p=0.048). Overall, grating acuity was significantly worse in the fellow eyes of amblyopes (p=0.016) than in healthy controls. Statistically prolonged latency for visual angles of 15' and 7.5' (p=0.018 and 0.002, respectively) was found in the strabismic group when compared with the control group. For the smaller visual stimulus (7.5'), statistically prolonged latency was found among all fellow eyes of amblyopic children (p&lt;0.001). Conclusions: The fellow eyes of amblyopic children showed worse optotype and grating acuity, with subtle abnormalities in the PR-VEP detected as prolonged latencies for smaller size stimuli when compared with eyes of healthy children. These findings show the deleterious effects of amblyopia in several distinct visual functions, mainly those related to spatial vision.

title: Evaluation of the safety of intracameral trypan blue injection on corneal tissue using oxidative stress parameters and apoptotic activity: an experimental study

description: Purpose: The present experimental study aimed to investigate the effects of intracameral trypan blue (TB) on oxidative stress parameters and apoptosis in corneal tissue. Methods: Thirty rats were randomly assigned to three groups of 10 rats each: the sham group (Group 1); control group (Group 2); and treatment group (Group 3). The control group was administered 0.01 cc of balanced salt solution. The treatment group was administered 0.006 mg/0.01 cc of TB. The total antioxidant status (TAS) and total oxidant status (TOS) in corneal tissue and blood were measured and the oxidative stress index (OSI) was calculated. Finally, corneal tissue histopathology was evaluated using staining for caspase-3 and -8, and apoptotic activity was examined. Results: The TAS, TOS and OSI levels in the blood samples were not significantly different (p&gt;0.05 for all). Compared with the sham and control groups, the TOS and OSI levels in corneal tissue were significantly different in the treatment group (p&lt;0.05 for all). No significant difference was observed between the sham group and the control group (p&gt;0.05). Immunohistochemical staining for caspase-3 and caspase-8 demonstrated higher apoptotic activity in the TB group than in the sham and control groups. Conclusion: The present study showed that intracameral TB injection is safe systematically but may be toxic to corneal tissue, as demonstrated using oxidative stress parameters and histopathological evaluation.

title: Hemorrhagic retinopathy in an infant with hemolytic-uremic syndrome

description: We describe the case of a 23-month-old female infant with a diagnosis of hemolytic uremic syndrome (HUS) and hemorrhagic retinopathy. The patient had a past history of abdominal pain, bloody diarrhea, and acute renal failure. On ophthalmologic examination, indirect ophthalmoscopy revealed extensive areas of flame-shaped hemorrhage, cotton wool spots, macular edema and optic nerve head neovascularization in both eyes. Fluorescein angiography showed severe bilateral retinal ischemia and neovascularization leakage in disk. The patient, who had the visual acuity of 20/1000 in the right eye (OD) and 20/540 in the left eye (OS) at the first examination, was treated with panretinal photocoagulation (PRP) and presented at the end of the 6th month of follow-up improvement to 20/540 in OD and 20/270 in OS. There was also a regression of disc neovascularization, hemorrhages and macular edema. Despite intense retinal ischemia, there were no complications related to angiogenesis such as vitreous hemorrhage and/or neovascular glaucoma. We describe, in this report, the association between hemorrhagic retinopathy with features of Purtscher-like disease and HUS.

title: THE PHENOMENOLOGICAL METHOD IN HEALTH RESEARCHES IN BRAZIL: AN ANALYSIS OF SCIENTIFIC PRODUCTION

description: Abstract Phenomenology as an inquiry method reveals itself as a possibility of making the relationship between the health professionals and the users of the health care system closer. This study aims to contribute to the process of philosophical appropriation of this perspective within the researches in this field. The research was conducted with the goal of analyzing the periodical scientific production related to this subject, identifying the phenomena assessed in these studies, the theoretical phenomenological perspectives adopted, as well as the fields of origin of the articles found between 2010 and 2014. The data were collected between December 2014 and February 2015 in the Scientific Electronic Library Online, Virtual Health Library (“Biblioteca Virtual de Saúde”, in Portuguese) and Capes Periodical Portal (“Portal de Periódicos Capes”, in Portuguese) databases. In the 17 selected articles, the prevailing field is nursing, which follows this metho-dology; Alfred Schutz is predominant as a philosophical guide, followed by Heidegger. In 12 of the works, the studied topics were related to women. Most of the studies did not provide reflections about the phenomenological research, focusing on hearing the narratives and on the phenomenal description that is revealed with the use of thematizations. The Brazilian publications are scarce, and, moreover, they do not provide enough guidance for the production of the investigation of the essences.

title: Effect of macular hole volume on postoperative central macular thickness

description: ABSTRACT Purpose: To evaluate the association between macular hole volume (MHV) and postoperative central macular thickness (CMT) using spectral-domain optical coherence tomography (SD-OCT). Methods: Thirty-three eyes of 30 patients with a large full-thickness idiopathic macular hole with or without vitreomacular traction who underwent surgical intervention were included in this cross-sectional study. Complete ophthalmological examination, including SD-OCT, was performed for all participants during the pre- and postoperative visits. MHV was preoperatively measured using SD-OCT, which captured the widest cross-sectional image of the hole. For normal distribution analysis of the data, the Kolmogorov-Smirnov test was performed, and for statistical analyses, chi-square, Student's t-test, Mann-Whitney U test, and Pearson's correlation coefficient test were performed. Results: Mean preoperative best-corrected visual acuity (BCVA) and MHV were found to be 0.99 ± 0.36 (range, 0.3-2.0) logMAR and 0.139 ± 0.076 (range, 0.004-0.318) mm3, respectively. Mean follow-up was 16.3 ± 14.3 (range, 3-50) months. No statistical correlations were found between MHV and postoperative BCVA (p=0.588) and between MHV and disease recurrence (p=0.544). A weak negative correlation existed between MHV and final CMT scores (p=0.04, r=-0.383). Conclusions: Greater MHV was found to be weakly associated with lower postoperative CMT scores.

title: ITALIAN TRADE UNIONISM BETWEEN CRISIS OF REPRESENTATIVITY AND CHANGES IN INDUSTRIAL RELATIONS

description: Abstract Since the beginning of the 1980s, the Italian confederal unionism (CGIL, CISL, UIL) has been undergoing a crisis of representativity, explained by the reduction in the rate of unionization and the difficulty of representing the new forms of employment produced by labor market reform processes in the last three decades. At the same time, it managed to defend the existence of national collective labor agreements, even if the attempts to overcome national category contracts have been more evident in recent years, but the same second-level negotiation has not gained more space. New forms of organization in the representation of precarious workers, outside the scope of the traditional union, and the greater dynamism of extra-confederal unions in the representation of immigrant workers are two elements that contribute to this crisis today. However, this does not mean the loss of its importance in the definitions of the regulatory norms in industrial relations and with the State on matters of collective interest in the world of work (social welfare, labor market, etc.).

title: Social Representations and Special Education Teacher’s Epistemological Conceptions of Learning

description: ABSTRACT: The purpose of this paper is to investigate the teacher’s epistemological conceptions of learning (n = 12) during the continuing teacher education program of a Basic Education School, Special modality, from Curitiba, Paraná, Brazil. The qualitative research was developed from the hermeneutic phenomenological perspective, drawing from the Theory of Social Representations as a theoretical and methodological resource for data analysis. The IRAMUTEQ software was used for statistical analysis data obtained through the protocol of the observation of the meetings. The continuing teacher education program took place over eight meetings lasting two hours each. For each meeting, one researcher registered the speeches of the participants (theme registration) and another one registered the movements of the group (dynamics registration). The register of the teachers’ statements during the meetings formed a textual body which was submitted to similarity analysis and the graphic representation of word clouds by IRAMUTEQ software, giving rise to the categories of analysis. The innate and empirical epistemological conceptions of learning coexisted in the teachers’ social representations. The conceptions were anchored in the organicist view of disability and ideas that reinforce the handicaps of children with disabilities and not their potentialities. As a consequence, teachers work on the preparation of children with disabilities for their integration into society, and not on educational actions aimed at their effective inclusion in society. The results refer to the teacher’s continuing education, the promotion of reflective discussions with the pedagogical team about the role of the special school and the encouragement of interdisciplinary work in the institution.

title: Characterization and attributes of herbaceous vegetation in a Caatinga fragment in the State of Sergipe, Brazil

description: ABSTRACT Variations in environmental factors are expected to be responsible for the diversification of herbaceous plants in the Caatinga (dry forest). We analyzed the composition, floristic similarity and structure of the herbaceous vegetation in a Caatinga fragment in the municipality of Poço Verde, Sergipe State, Brazil. In addition, the influence of precipitation on richness among different Caatinga areas was evaluated. We installed 30 subplots and the floristic composition was complemented by collections made around these subplots. A total of 80 species were found, of which 43% are typically from disturbed areas of Caatinga. Among the Caatinga areas, precipitation did not explain the variation of richness; similarity values were determined by environmental heterogeneity. The parameters of Shannon-Wiener diversity and Pielou's evenness were within the range expected for Caatinga disturbed areas. Based on evidence supported by previous studies, we believe that human disturbance influences the composition and the structure of the studied herbaceous vegetation. Therefore, conservation actions are recommended.

title: Abdominal muscular endurance in Brazilian children and adolescents: systematic review of cross-sectional studies

description: Abstract The literature has demonstrated the importance of musculoskeletal fitness in the prevention of chronic noncommunicable diseases. Although current recommendations of physical activities include strengthening and muscular endurance aspects, little is known about the muscular endurance levels of children and adolescents in a national scope. The aim of this study was to systematically review the literature to identify the prevalence of Brazilian children and adolescents who meet health criteria for muscular endurance. A hierarchical search was conducted in four databases (MEDLINE; Scopus; SciELO; LILACS) using the following terms: “muscular endurance”, “muscle endurance”, “physical fitness”, “child”, “adolescent”, “adults” “school” and correspondents in the Portuguese language. Overall, 2,652 articles (2,269 had their title and abstract read) were found and 70 were eligible for reading in full. Seventeen studies were reviewed and evaluated for risk of bias. Among 32,661 children and adolescents, only 40.2% of boys and 31.9% of girls presented abdominal muscular endurance adequate for health, and most studies were conducted in the southern region of Brazil. The variability in procedures for evaluating abdominal muscular endurance and cut-points used for interpretation occurred due to the use of different standardizations (PROESP/BR®, FITNESSGRAM® and AAHPERD®). Less than half of Brazilian adolescents of both sexes have adequate abdominal muscular endurance for health. Studies investigating the causes and consequences of inadequate abdominal muscular endurance may contribute to strategies for disease prevention and health promotion of children and adolescents.
