Patients are looking for esthetic and functional changes when seeking orthodontic treatment and expect the remaining of a stable occlusion. Occlusion stability is one of the goals of the orthodontist; however, dental relationships changes in long-term can occur leading to a relapse of the treatment. Teeth and shape of arches tend to return to the original form, been the retention phase important after the appliance removal, even after several years of post-treatment. This article approaches a submission of a clinical case of Class II division 1 treated with extraction of premolars analyzing its long-term stability.

The early malocclusion treatment has increased interest of orthodontic community. Among these is the serial extraction that harmonizes the differences between the amount of dental material and permanent deficiency of supporting bone. The technique is applied in mixed dentition through a predetermined sequence of extractions between deciduous and permanent teeth, in order to reach spontaneous immediately alignment of remaining permanent teeth with a minimum orthodontic mechanics. It will be reported a case where the serial extraction was performed in a growing patient with biprotrusion, Class I malocclusion and severe crowding. All functional and aesthetics goals were reached.

The correction of a Class III malocclusion in adult patients is one of the major challenges in orthodontics due to facial deformities occurring during the unfavorable growth of this kind of pattern, as well as the treatment options capable of producing facial changes aesthetically acceptable and adequate for today's beauty standards. One acceptable alternative treatment is the removal of a lower incisor. For a Class III correction through a lower incisor extraction a thorough analysis and planning must be carried out by taking into consideration the amount of overjet and overbite, periodontal condition of the teeth and the possibility of obtaining a good dental occlusion with acceptable facial aesthetics. Will be presented two case reports of patients presenting an anteroinferior crowding, Class III malocclusion condition. The treatment through a lower incisor extraction and the reasons why this treatment was adopted will be discussed.

A catarata é a afecção da lente mais comum em cão, caracterizada por uma opacidade do cristalino e alteração de comportamento devido ao déficit visual. O exame oftálmico adequado e completo da lente permite a classificação adequada da catarata auxiliando na escolha do melhor tratamento de cada paciente. O tratamento preconizado para a catarata é o procedimento cirúrgico, que associado com o uso de anti-inflamatórios, midriáticos e antibióticos pré-operatórios e pós-operatórios melhoram os resultados visuais e previnem algumas complicações. A remoção da lente pode ser feita pelas técnicas de discisão, extração intracapsular, extração extracapsular e facoemulsificação, sendo que a escolha correta da técnica para cada caso contribui para o sucesso do procedimento e diminui as complicações pós-operatórias, porém as técnicas de escolha para a remoção da catarata são a extração extracapsular e a facoemulsificação. O objetivo da revisão sistemática é comparar as complicações de duas das técnicas para extração da catarata, extração extracapsular e facoemulcificação, ressaltando qual a técnica que apresentou menores complicações em cães. Foram analisados dez artigos pesquisados nas bases de dado PubMed e Google Acadêmico, sendo complementados com o uso de livros. Foram encontradas como complicações perda da visão, glaucoma, descolamento de retina, hemorragia intraocular, ruptura da cápsula posterior, alterações corneanas, endoftalmites, sinéquia posterior, fotofobia, blefaroespasmo e hiperemia conjuntiva. Essas complicações foram descritas em ambas as técnicas, porém inúmeros fatores

Persistent Organic Pollutants (POPs) are chemical substances extraordinarily toxic and persistent in the environment. Due to these properties, POPs are targets of the Stockholm Convention which aims to provide means to eliminate production and use by encouraging the reduction and, where possible, eliminating the release of these contaminants to the environment. One of the articles of this _Convention aims to assess the basal levels of such substances in the environment to monitor both the reduction of release to the environment, and to assess human exposure, using analyzes of milk and air for example. Although efforts to control POPs production and release to the environment have been made, data about their levels in Brazil are still scarce, mainly in the atmosphere or indoor environment. Considering the permanence of people inside its house, this study presents a method for POP extraction from XAD-2 sorbent employed in indoor air sampling, with identification and quantification by GC-ECD. GC-ECD linear range of the studied analytes, congeners of polychlorinated biphenyls (PCB) (28, 52, 101, 118, 138, 153 and 180), DDTs and their metabolites (DDDs, DDEs) and endosullan (isomers c - and 13 - and metabolite endosulfan sulfate) ranged between 0.5 and 16.0 ng mL-I with r2 > 0.967. The method developing consist of selecting the extraction solvent system by agitation (90 rpm, 1 hour) with n-hexan,e (2 mL) or n-hexane:acetone (1:1, v/v) (2 mL), concentration the extract with a gentle N2 stream, and evaluation of breakthrough with passage or air through the fortified XAD-2 cartridge before extraction, employing a low volume air suction pump (Pump Model 224 universal-PCXR8; 5-5000 mL min-1, SKC Inc., Eighty Four, PA, USA), Calibrator Dry-Cal DC-Lite (BIOS, Butler, NJ, USA)). Two fortification levels were employed, 15 and 30 ng. After selecting n-hexane as extraction solvent, with accuracy and precision ranging...
