title: DRESS syndrome in ophthalmic patients

description: ABSTRACT Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal adverse drug reaction associated with skin rash, fever, eosinophilia, and multiple organ injury. A number of pharmacological agents are known to cause DRESS syndrome such as allopurinol, anticonvulsants, vancomycin, trimethoprime-sulfamethoxazole, and pyrimethamine-sulfadiazine. Here, we describe two patients who developed DRESS syndrome during ocular treatment. The first case was being treated for late postoperative endophthalmitis with topical antibiotics, intravenous cephalothin, meropenem, and intravitreal injection of vancomycin and ceftazidime before symptoms developed. We were unable to identify the causal drug owing to the large number of medications concurrently administered. The second case presented with DRESS syndrome symptoms during ocular toxoplasmosis treatment. In this case, a clearer association with pyrimethamine-sulfadiazine was observed. As a result of the regular prescription of pharmacological agents associated with DRESS syndrome, ophthalmologists should be aware of the potentially serious complications of DRESS syndrome.

title: ANATOMICAL AND CHEMICAL PROPERTIES OF JUVENILE Schizolobium amazonicum WOOD

description: ABSTRACT The objective of this study was to determine the effects of tree age and of pith-bark and base-top positions on anatomical characteristics, and the effect of age on the chemical components of Schizolobium amazonicum (Paricá wood). The material was obtained from commercial plantations in the states of Maranhão and Pará with ages of 5, 7, 9 and 11 years. The first three logs (2.7 m length each) were obtained from the trees of each age. Only the effect of age was analyzed for the chemical characterization of the wood. The dimensions of the fibers increased along the pith-bark direction, while wall thickness decreased and the length of the fibers increased with aging. The width of the fibers and the lume diameter increased in the base-top direction. Paricá wood presented low extractive and hemicellulose content, and high cellulose content. The anatomical characteristics were more affected by the factors under study than the chemical composition, evidencing that the chemical elements of the wood are more stable with aging in relation to the anatomical characteristics.

title: Keratoacanthoma of the conjunctiva in a young patient

description: ABSTRACT Keratoacanthomas rarely occur in the conjunctiva. We report a case of a 24-year-old man with a rapidly growing conjunctival mass. The tumor was excised with a safety margin to exclude squamous cell carcinoma and was histopathologically diagnosed as a keratoacanthoma. There has been no recurrence over 2 years of follow-up. To the best of our knowledge, he is the youngest patient to be diagnosed with conjunctival keratoacanthoma who had no known risk factors such as skin disorders, trauma, surgery, or infection. In similar cases, we recommend complete early surgical excision and careful follow-up to exclude malignancy.

title: COST OF FOREST INSURANCE IN THE ECONOMIC VIABILITY OF EUCALYPTUS PLANTS

description: ABSTRACT The objective of this study is to carry out economic and risk assessment of eucalyptus plantations located in Minas Gerais, considering the influence of the cost of forest insurance, evidencing its impact on the project. The costs of implementation and driving come from eucalyptus plantations located in the Jequitinhonha Valley, Minas Gerais. The cost of forest insurance was obtained through a simulation of a quote from an insurer. For the economic evaluation, the Net Present Value (NPV), the Internal Rate of Return (IRR) and the Equivalent Periodic Benefit (EPB) were used. The risk sensitivity analysis was performed by the Monte Carlo method. The economic analysis was considered viable by all indicators used in all three situations. However, by the analysis of investment risk, we have a probability of 11.5% chance of NPV being below zero in situation 1, 18.5% in situation 2 and 25% in situation 3. The cost of Forest insurance increases the likelihood of negative value for economic indicators, as it increases the cost of the project, but it was input that less influenced the final value of the NPV. The government grant reduces the likelihood of investment risk as it lowers the cost of forest insurance.

title: Prevalence of Treponemaspp. in endodontic retreatment-resistant periapical lesions

description: This study investigated the presence of the Treponema species in longstanding endodontic retreatment-resistant lesions of teeth with apical periodontitis, the association of this species with clinical/radiographic features, and the association among the different target species. Microbial samples of apical lesions were collected from twenty-five adult patients referred to endodontic surgery after unsuccessful root canal retreatment. Nested-PCR and conventional PCR were used for Treponema detection. Twenty-three periradicular tissue samples showed detectable levels of bacterial DNA. Treponema species were detected in 28% (7/25) of the cases. The most frequently detected species were T. socranskii (6/25), followed by T. maltophilum (3/25), T. amylovorum (3/25), T. lecithinolyticum(3/25), T. denticola (3/25), T. pectinovorum (2/25) and T. medium(2/25). T. vicentii was not detected in any sample. Positive statistical association was found between T. socranskiiand T. denticola,and between T. maltophilumand T. lecithinolyticum. No association was detected between the presence of any target microorganism and the clinical or radiographic features. Treponemaspp.are present, in a low percentage, in longstanding apical lesions from teeth with endodontic retreatment failure.

title: Microstructure, Mechanical Properties and in vitro Biological Behavior of Silicon Nitride Ceramics

description: The bioinert surface of silicon nitride ceramics led us to investigate the additions of SiO2, CaO and Al2O3 in order to aid the liquid phase sintering and improve the mechanical properties and biological behavior of the final materials. The sintered materials reached ca. 97% of theoretical density and total α→β-Si3N4 transformation. The samples had relatively high values of fracture toughness while their elastic modulus values were lower than those of conventional silicon nitride ceramics. Apatite deposits were observed on the surfaces analyzed after SBF (simulated body fluid) immersions, suggesting their bioactivity. Osteoblasts proliferation and calcified matrix were also detected as response to cells/materials contact. This combination of properties suggests that all studied compositions are promising for applications in biomedical devices. Moreover, compositions with alumina additions and higher silica content had better in vitro biological behavior, densification and mechanical properties, suggesting greater potential to be used in bone substitute devices.

title: Effect of Growth Velocity and Zn Content on Microhardness in Directionally Solidified Al-Zn Alloys

description: In this study, Al-xZn (x=1, 3, 5, 7, 10 and 20 wt. %) alloys were prepared using metals of 99.99% high purity in the vacuum atmosphere. These alloys were directionally solidified upward with a constant temperature gradient, G (10.3 K/mm) and different growth velocities (V) between 8.25 and 165 µm/s in the directional solidification apparatus. The experimental results have revealed that with the increase of the growth velocity of the melts from 8.25 µm/s to 165 µm/s, the microstructures undergo a transition from cellular/cellular dendritic morphology to coarse dendritic form for each composition (Zn content, Co). The measurements of microhardness (HV) of the specimens were performed by using a microhardness test device. The dependence of HV on V and Co was analyzed, and it has been found that with increasing the V and Co the HV increases. Relationships between HV-V and HV-Co were obtained by linear regression analysis, and the experimental results were compared with the results of previous similar works.

title: A Comparison Among Simple Algorithms for Linear Programming

description: ABSTRACT This paper presents a comparison between a family of simple algorithms for linear programming and the optimal pair adjustment algorithm. The optimal pair adjustment algorithm improvements the convergence of von Neumann’s algorithm which is very attractive because of its simplicity. However, it is not practical to solve linear programming problems to optimality, since its convergence is slow. The family of simple algorithms results from the generalization of the optimal pair adjustment algorithm, including a parameter on the number of chosen columns instead of just a pair of them. Such generalization preserves the simple algorithms nice features. Significant improvements over the optimal pair adjustment algorithm were demonstrated through numerical experiments on a set of linear programming problems.

title: FROM VISIBLE TO NAMED: FRAMINGS OF THE HUMAN

description: ABSTRACT Through a cross reading that we put into relation, this paper tries to understand the processes of the constitution of senses and the production of subjectivities, having as an object a series of images, utterances and enunciations. We take the question of vagrancy as a place to think about how a kind of violence returns as it moves through the centuries in both its practices of repression and transgression. The objects to which we direct our eyes are thought of as events, in the sense that they are a kind of meeting point between a very familiar memory, that of slavery, of feminicide and of the crime of vagrancy in Brazil, with a and perversely daily reality, the contemporary (and not so contemporary) forms of life management, border demarcation and asymmetric distribution of violence by the state.

title: PROGRAMMATIC VULNERABILITY AS A CATEGORY TO EXPLAIN ETHICAL PROBLEMS WITHIN PRIMARY HEALTH CARE

description: Abstract Ethical problems in public health – especially those concerning primary health care – require a specific and adequate approach. The factor analysis of quantitative data about ethical problems in primary health care pointed to management, longitudinality, team experience, professional profile, secrecy and privacy as specific topics. In the subsequent qualitative stage, we searched for examples and solutions through a focal discussion with primary health care teams in the cities of Porto Alegre and Sapucaia do Sul, in the state of Rio Grande do Sul, Brazil. The adopted methodological approach was the Grounded Theory. The analysis of the results had as reference points the causal and intervening conditions and the strategies for action when facing these problems. The fragmentation of care and the lack of prominence, caused by insufficient planning and permanent education, weaken the users and the professionals. The refinement of these results through selective codification reached the nuclear category of programmatic vulnerability as an explanatory category for the occurrence of ethical problems in primary health care.

title: Methylene blue-related corneal edema and iris discoloration

description: ABSTRACT We report the case of a 70-year-old female patient who developed corneal edema and iris discoloration following the inadvertent use of 1% methylene blue instead of 0.025% trypan blue to stain the anterior capsule during cataract phacoemulsification surgery. Copious irrigation was performed upon realization of incorrect dye use. Corneal edema and iris discoloration developed during the early postoperative period and persisted at 24-months follow-up. However, keratoplasty was not required. The intracameral use of 1% methylene blue has a cytotoxic effect on the corneal endothelium and iris epithelium. Copious irrigation for at least 30 min using an anterior chamber maintainer may improve outcomes.

title: AEROBIC TRAINING IN OBESE ADOLESCENTS: A MULTIDISCIPLINARY APPROACH

description: ABSTRACT Introduction: The prevalence of excess weight/obesity in adolescence has increased, and physical training may be effective in combating this scenario. Objective: To analyze the effect of different intensities of aerobic training on the body composition of obese adolescents undergoing multidisciplinary intervention. Methods: In this study, 107 pubertal (Tanner 3 and 4), obese (BMI=34.72±4.10 kg/m²) adolescents (14.85±1.44 years) were randomly assigned to three groups: high intensity training (HITG – ventilatory threshold I (VTI)); low intensity training (LITG – 20% below the VTI) and control group (CG), without intervention. The adolescents in the HITG and LITG underwent nutritional and psychological (1x/week) and clinical (1 x/month) follow-up and physical training (3x/week) for 12 weeks. Results: Reductions in fat mass (FM) and body fat percentage (BFP) (p&lt; 0.001) and an increase in fat-free mass (FFM) (p&lt;0.001) were observed in all groups. There was a reduction in BMI only in the experimental groups (p&lt;0.001). Conclusion: The effects of multidisciplinary treatment on the body composition of obese adolescents occur independently of the intensity of aerobic physical training. Level of Evidence I; High quality randomized clinical studies with or without statistically significant difference, but with narrow confidence intervals.

title: Panophthalmitis with orbital cellulitis following glaucoma drainage implant surgery in a pediatric patient

description: ABSTRACT Here we report a case of childhood glaucoma refractory to angle and trabeculectomy surgery. The patient was treated with an Ahmed™ drainage implant that was subsequently complicated by rapid-onset panophthalmitis and orbital cellulitis. Intravenous and intravitreal antibiotic therapy was initiated and the drainage tube was removed. The infectious process resolved within 3 weeks; however, phthisis bulbi developed subsequently.
