title: Impact of wildfire smoke in Buenos Aires, Argentina, on ocular surface

description: Purpose: To evaluate the acute impact of the wildfire smoke episode in 2008 on the ocular surface of subjects living in the Metropolitan Area of Buenos Aires (MABA). Methods: A total of 86 subjects were evaluated: Group 1 comprised patients from a public ophthalmology hospital (N=35) and Group 2 comprised healthy volunteers (N=51). All subjects answered a questionnaire on ocular symptoms and underwent ophthalmologic examination [bulbar conjunctival hyperemia, corneal fluorescein staining, rose bengal vital staining, tear break-up time (TBUT), Schirmer I test, tear lysozyme, and impression cytology] during and after the acute episode. Concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), and particulate matter (PM) were measured before, during, and after the acute episode. Results: Both groups showed a statically significant increase in ocular symptoms and bulbar conjunctival hyperemia and a statically significant decrease in tear break-up time during the acute episode. Group 1 showed more severe symptoms and a statistically significant increase in fluorescein and rose bengal staining intensities during the acute episode. We found a significant negative correlation between ocular symptoms and tear break-up time. During the episode, the levels of CO, NO2, and particulate matter in MABA were four times higher than the usual average levels for the same period in 2007 and 2009. Conclusions: Increased air pollution from the burning of biomass is associated with a decrease in the stability of the tear film (TBUT), generating areas of ocular surface exposure that may be the cause of the increased feeling of irritation. Group 1 was more affected by not having a healthy ocular surface, and thus consulted an ophthalmologist. Cytological changes in the conjunctiva were not observed, which could be due to the short duration of the episode.

title: Bilateral acute iris transillumination (BAIT) initially misdiagnosed as acute iridocyclitis

description: Bilateral acute iris transillumination (BAIT) is a relatively new clinical entity characterized by bilateral acute loss of iris pigment epithelium, iris transillumination, pigment dispersion in the anterior chamber, and sphincter paralysis. We report the case of a 30-year-old male who was initially diagnosed with acute iridocyclitis in a different clinic and treated with topical and systemic corticosteroids. He was referred to our clinic to seek another opinion because his symptoms did not improve. An ocular examination revealed bilateral pigment dispersion into the anterior chamber, diffuse iris transillumination, pigment dusting on the anterior lens capsule, atonic and distorted pupils, and increased intraocular pressure, suggesting a diagnosis of BAIT rather than iridocyclitis. Clinicians should be aware of the differential diagnosis of syndromes associated with pigment dispersion from iridocyclitis to avoid aggressive anti-inflammatory therapy and detailed investigation for uveitis.

title: Flexibility in Brazilian children and adolescents: a systematic review

description: Abstract Flexibility is a health-related physical fitness component that has its importance related to the maintenance of functional independence and achievement of activities of the daily living. This systematic review aims to analyze the existing evidence in the literature regarding physical capacity flexibility in Brazilian children and adolescents. Searches were conducted in the Virtual Health Library, Scientific Electronic Library Online, Sportdiscus databases through the EBSCOhost and Pubmed platform. There were 89,553 articles, of which 69,197 were excluded for duplicity, 20,124 for the title, 160 for the abstract, 56 after a full analysis of the article, remaining 16 articles for the qualitative analysis. Of these, from the reading of references, 57 titles partially eligible for the review were identified, and after the application of the eligibility criteria, there were only 18 for the qualitative analysis. Of the 34 studies included for the qualitative analysis, 25 studies were excluded and nine were included in the review. All articles presented the cross-sectional design and used the sit-and-reach test to assess flexibility. It was evidenced that: a) flexibility has been treated as co-adjuvant in studies with children and adolescents; b) although females have absolute flexibility values greater than the opposite sex, males have higher frequency of subjects that meet the health classification criteria in this variable; c) there is greater prevalence of the use of FITNESSGRAM and PROESP-BR reference standards.

title: Oculo-peritoneal shunt: draining aqueous humor to the peritoneum

description: In 2010, there were estimated to be approximately 60.5 million people with glaucoma. This number is expected to increase to 79.6 million by 2020. In 2010, there were 8.4 million people with bilateral blindness caused by glaucoma, and this number is expected in increase to 11.2 million by 2020. Filtering implants are special devices that have been developed to reduce intraocular pressure in patients with refractory glaucoma. The success rate of these implants is relatively low, and they continue to fail over time. To avoid failure caused by the formation of scar tissue around the implants, attempts have been made to drain the aqueous humor to various sites, including the venous system, lacrimal sac, sinuses, and conjunctival fornix. Recently, a system to shunt aqueous humor from the anterior chamber to the peritoneum has been developed. The surgical technique involved in this system is a modification of the technique currently used by neurosurgeons for the treatment of hydrocephalus. We present the first case operated using this technique.

title: Impression cytology in the evaluation of ocular surface tumors: review article

description: Impression cytology (IC) has been widely used as a method for evaluating the ocular surface and superficial cells layers in the diagnosis and follow-up after treatment of several ocular surface tumors of both epithelial and melanocytic origin. Information regarding this can be found in the English-language literature since 1992. Using either cellulose acetate or Biopore membranes for specimen collection, a high correlation has been found between IC and tissue histology. Compared with exfoliative cytology with spatula, IC is less traumatic to the patient’s eye, provides a precise location of the area being studied, and allows accurate observation of the cells the way they exist in vivo. The additional advantage of IC is the preservation of limbal stem cells responsible for continuous corneal epithelium renewal; these can be affected after incisional or excisional biopsy at the corneoscleral limbus, which is the most frequent site of appearance of tumors in the stratified epithelium. Treatment for ocular surface squamous neoplasia has historically included surgery, but nonsurgical interventions have also been adopted. Hence, in certain cases, ophthalmologists may prefer interventions less invasive than surgical biopsy such as of impression cytology for both initial diagnosis and therapeutic monitoring of treatment for ocular surface lesions. Nevertheless, it should be considered that IC may be less helpful if the results conflict with the clinical picture or if the clinical diagnosis is uncertain and results are negative. In such cases, surgical biopsy is required for accurate diagnosis. The purpose of this review is to examine the published literature on the utilization of IC for the diagnosis and management of ocular surface tumors and to discuss the requirement for further investigation on the subject.

title: Macular dystrophy associated with Kjellin’s syndrome: a case report

description: Hereditary spastic paraplegia (HSP) is characterized by weakness and spasticity of the lower extremities. Kjellin’s syndrome is a rare syndrome associated with HSP. The syndrome is characterized by the presence of bilateral retinal flecks, similar to the findings in Stargardt disease and fundus flavimaculatus. We report the case of a 34-year-old male who presented with complete features of Kjellin’s syndrome, with typical retinal findings observed on multimodal imaging (spectral domain optical coherence tomography [SD-OCT], near-infrared reflectance and autofluorescence imaging). The ophthalmological changes at early stages of the disease may not impair visual acuity. Therefore, the detection of central retinal degeneration requires thorough fundus examination.

title: Together yet separate: variation in soil chemistry determines differences in the arboreal-shrub structure of two contiguous rupestrian environments

description: ABSTRACT Rupestrian landscapes are characterized by vegetation mosaics comprised of different plant communities and strongly linked to environmental filters. These environments are nutrient-impoverished, and possess water retention deficits and high solar exposure. This study aimed to determine whether chemical properties of the soil shape the arboreal-shrub vegetation structure in two neighboring habitats; a rupestrian cerrado and a rupestrian grassland. We hypothesized that the habitat with higher soil chemical properties would have higher parameters for vegetation structure, and different species composition. We expected higher chemical properties of the soil to favor a greater variety of plant life-forms. A total of 1349 individuals of 85 species belonging to 24 families were recorded; 1141 individuals (65 species) in the rupestrian cerrado, and 208 individuals (20 species) in the rupestrian grassland. Overall, Asteraceae, Fabaceae and Melastomataceae had greater species richness in both areas. Both habitats floristic composition was strongly influenced by differences in soil chemistry. In the cerrado, species richness, composition, soil nutrient availability and acidity were greater than in the grassland. We demonstrated that variation in soil chemistry influences plant species richness and composition, and structural complexity of vegetation, in both contiguous rupestrian environments, and that soil chemistry heterogeneity yields different plant life-form strategies.

title: Pedagogical Preparation for Physicians and their Performance in the Medical Course

description: ABSTRACT Qualifying the medical profile to meet the population’s main health needs is a challenge for contemporary medical schools. In this process, the medical professor has a prominent place, since medical teaching practice is based on the production of models considered valid, previously learned, and the experience of medical practice. One questions, thus, the physician’s pedagogical aptitude to teach, since the professor-academic relationship occurs differently from the physician-patient relationship, starting from the need to understand which ways professors seek to acquire the teaching-specific skills. Objective To carry out an integrative review on the pedagogical training of physicians in the teaching context. Methods This is a non-observational, descriptive integrative review of the literature. Initially, we searched the databases at the Scientific Electronic Library Online (SciELO), Latin American and Caribbean Literature in Health Sciences (Lilacs), the US National Library of Medicine and the National Institutes of Health (PubMed) and the Cochrane Library with the help of the Boolean operator and the following descriptors: Health Human Resource Training; Faculty, Medical and Education, Medical, Continuing. The inclusion criteria were free, complete articles, published from 2012 to 2016, in Portuguese, Spanish and English. Results The search resulted in 24 articles those discuss the research theme. After exhaustive reading of the articles found, only five converged and answered the guiding question raised in the initial reflection. Teaching strategies and methodologies, as well as the evaluation of clinical supervision processes to construct the students’ technical knowledge appear as important topics on learning and teaching. In addition, these discussions raise professors’ need for continuing education programs, as well as the construction of evaluation tools for professors, tutors and preceptors. Conclusions This study highlights the continuous improvement in the professors’ pedagogical training and the development of permanent education programs and improvement of the faculty by the school.

title: Six-month outcomes of corneal crosslinking with dextran-free isotonic riboflavin solution

description: ABSTRACT Purpose: To analyze the short-term clinical and topographic outcomes in patients with keratoconus after corneal collagen cross-linking treatment (CXL) with dextran-free isotonic riboflavin solution. Methods: In this retrospective case series, 26 eyes from 26 patients with keratoconus were studied. The best corrected visual acuity (BCVA) and refractive and topographic findings were analyzed at a 6-month follow-up. Results: The mean BCVA (Snellen lines) values before and 1, 3, and 6 months after CXL were 0.51 ± 0.2, 0.48 ± 0.2, 0.57 ± 0.2, and 0.64 ± 0.2, respectively, and the difference between the preoperative and 6-month values was statistically significant (p=0.006). The mean spherical equivalent refraction decreased from -5.6 ± 2.4 diopters (D) preoperatively to -5.0 ± 2.1 D, and mean simulated keratometry decreased from 48.5 ± 2.5 D to 47.8 ± 2.6 D at 6 months. (p=0.145 and p=0.001, respectively). In addition, the maximum keratometry decreased progressively and significantly from the preoperative value during follow-up (p=0.003). The central and minimal corneal thicknesses, including those of the epithelium, also decreased from 442.8 ± 25.6 µm and 430.5 ± 23.9 µm preoperatively to 420.7 ± 31.8 µm and 409.3 ± 28.7 µm at the most recent follow-up (p&lt;0.001), respectively. No intraoperative or postoperative complications were observed. Conclusions: CXL with dextran-free isotonic riboflavin solution appears to be a safe treatment alternative for keratoconus and yields sustained short-term improvements in visual acuity, keratometric readings, and corneal thickness. However, long-term results are needed to confirm these outcomes.
