Motorcycle accidents have been rapidly growing throughout the years in many countries. Due to various social and economic factors, this type of vehicle is becoming increasingly popular. Over the past years, automated mechanisms to inspect traffic violations such as radars and surveillance cameras are being used ever more. This paper’s goals are the study and implementation of some methods for automatic detection of motorcycles on public roads. Traffic images captured by cameras were used. For feature extraction of images, the algorithms SURF, HAAR, HOG and LBP were used as descriptors. For image classification, Multilayer Perceptron, Support Vector Machines and Radial-Bases Function Networks were used as classifiers. Finally, the results are presented and discussed.

The objective of the study is to establish the main aspects of workers' exposure to chemical agents and to define the relationship with the risks capable of making their health and quality of life unstable. This is an integrative review of the literature, in which the studies and works made available on the SCIELO and Google Scholar platform were compiled and analyzed theoretically. As a result, the nursing actions of the work in the awareness of the participating agents, the strategic degree actions to maintain the psychological and physical conditions, the effective participation of the states and organs in the formulation of preventive proposals, the relevance of protective equipment aiming at the elimination of risks and enhancing the personal safety of the worker, are strong and positive points for the prevention of risk to workers. The involvement of nursing professionals in the construction and implementation of actions and programs needs to be stimulated, emphasizing systematic efforts in the area of health, especially in primary health care.

We live in a technological world and full of constant changes, which is not distinctive when it comes to health. The enteroparasitoses are a serious problem and that has affected the population, mainly the citizens who do not have adequate hygienic-sanitary conditions. The objective of this article is to search for available evidence in the literature on the prevalence of epidemiological aspects of enteroparasitosis in children in Brazil. The study was carried out by means of a bibliographical review, through a survey of scientific articles using the main bases of scientific indexing, such as: Scielo and MedLine. The prevalence of enteroparositosis in Brazil is high, with social problems and partial access to public policies as collaborators in the spread of diseases, among them intestinal parasitoses, of which they occupy the top. Public health policies should be inserted and enjoyed by the unassisted community in these places, since children by virtue of their physiological conditions are more sensitive to such manifestations.

RESUMO.Os otohematomas ou hematomas aurais são alterações resultantes de um acúmulo de sangue dentro da cartilagem auricular, ocasionados por diversos fatores, como otites de variadas etiologias. Existem vários procedimentos clínicos e cirúrgicos para o tratamento do otohematoma, porém nem todos trazem resultados satisfatórios. Este relato tem por objetivo relatar o caso de um felino, sem raça definida, de quatro anos e quatro meses de idade, diagnosticado com hematoma aural recidivante, devido à otite. Palavras chave: Felino, hematoma aural, otite Aural hematoma in young cat: Case reportAbstract. Otohematoma or aural hematoma are affections defined as an accumulation of blood within the atrial cartilage, caused by several factors, such as otitis of many etiologies. There are several clinical and surgical procedures for the treatment of otohematoma, but few with satisfactory results. The purpose of this arcticle is to report a case of a four year and four months old feline, diagnosed with recurrent aural hematoma due to otitis.

Plants with potential biological activity in the organism have important applicability in the present day as soon as the use is present in the culture of which it was adhered by the ancestors. The mikania, better known as guaco is used for several pathological conditions, both for cases related to the respiratory system and anti-inflammatory functions in various organs. This work aims to review the literature on the pharmacological effects of Mikania and to know the most used species. In studies done, it was verified that Mikania have several pharmacological effects, with antibacterial in dental infections, anti-hemorrhagic in cases of snakebite, anti-nociceptive with opioid-like actions, anti-inflammatory and antipyretic, useful in cases such as dengue. And this is due to its chemical constitution, since it holds a concentration of important active substances, especially coumarins. It is evident that secondary metabolites have biological activities in the body, with desired effects. M. glomerata was the most searched with positive results against tests. More effort is needed in the evaluation of compounds that can be used by society in the form of drugs with minimal side effects.

Background: The brown bear (Ursus arctos) is considered one of the largest terrestrial carnivores, native from temperate forest regions of North America, Europe and Asia. In Brazil, they are founded in captivity and their safe capture and immobilization are obtained with one effective anesthesia for management and surgical and diagnostic procedures. Some anesthetic protocols are described for these purposes, however, there is a lack for data on the anesthetic and adverse effects they have on bears when used. The aim of this case is to report the use and effects of the association of dexmedetomidine with tiletamine and zolazepam in the chemical containment of a captive adult brown bear.Case: A 33-year-old female brown bear, weighing 100 kg, belonging to the Zoobotanic Park of Teresina, Piauí, Brazil, was chemically immobilized for an incisional biopsy of a cutaneous nodule with 1.0 cm diameter in the right face region. The anesthetic protocol included 6 μg/kg of dexmedetomidine associated with 3 mg/kg of tiletamine and zolazepam, administered intramuscularly by dart into the gluteal region of the right pelvic limb. The animal showed moderate ataxia at 5 min and assumed sternal decubitus 7 min after anesthetic administration. The bear's degree of sedation was considered adequate and safe to perform the biopsy at 10 min after administration. Heart rate (47 ± 3 bpm), respiratory rate (17 ± 2 mpm) and rectal temperature (38.7 ± 0.1ºC) were monitored. The bear remained immobile and unconscious throughout the procedure, with intense muscle relaxation, bilateral eyeball rotation, absent lateral palpebral reflex and mild medial reflex and without nystagmus. Complementary sedative doses were not necessary. At the beginning of anesthetic recovery, the bear received 6 µg/kg of atipamezole, intramuscularly. After 25 min of administration of atipamezole, the animal showed signs of recovery in the level of consciousness and reactivity to external stimuli, and assumed the quadrupedal position at 60 min after reverser application.Discussion: Even in captivity, the bears behavior is unpredictable and attack can occur, causing trauma or death to people. For this, the chemical immobilization is important to keep safety of everyone. This procedure was performed using blowgun-assisted darts thrown by a staff member who had experience in using this method, who darted accurately and effectively. The latency time observed after administration of the anesthetic protocol used is similar to reported in other studies with bears that also received intramuscular dexmedetomidine and tiletamine and zolazepam and showed intense muscle relaxation and immobility. The doses used contributed to the absence of bradycardia and hypoventilation and, performing the procedure in the morning, when the temperature is milder in the city, minimized the chance of hyperthermia and thermal stress in the animal, not requiring body cooling. The use of dexmedetomidine in chemical containment protocols for short and minimally invasive procedures allows the subsequent use of its antagonist, atipamezole, contributing to a shorter recovery time, return of the animal’s degree of consciousness and lower incidence of ataxia after assuming a quadrupedal position. The anesthetic protocol used was considered efficient, providing a quick and gentle chemical containment, adequate anesthetic plan and good anesthetic recovery in an adult brown bear from captivity.Keywords:atipamezole, dexmedetomidine, wildlife.Título: Manejo anestésico de um urso pardo (Ursus arctos) cativo submetido a biópsia incisional de nódulo cutâneoDescritores: atipamezole, dexmedetomidine, animais selvagens.
