The preemptive analgesia with ibuprofen was insufficient to inhibit central sensitization, whereas its association with dexamethasone was more effective in preventing pain in third molar surgery.

Under these experimental conditions, there is no advantage in the administration of antibiotics in healthy patients undergoing extraction of fully impacted lower third molars with a controlled aseptic chain.

A double‐blind multicentre study was undertaken to compare the efficacy and safety of remoxipride in a controlled release (CR) formulation given once daily with haloperidol twice daily in patients with schizophrenic illness. In total, 114 patients were included. All were diagnosed as schizophrenic or schizophreniform according to DSM‐III. Their mean daily dose of remoxipride CR during the last week of treatment was 385 mg. In the haloperidol group the corresponding dose was 17 mg per day. The intended study period was 4 weeks with at least a one‐day washout. No significant differences were found between treatments regarding efficacy variables. The median total Brief Psychiatric Rating Scale (BPRS) score was 40 in the remoxipride CR group at start of treatment and 21 at last valid rating. For the haloperidol group the corresponding figures were 40 and 22. Treatment‐emergent extrapyramidal symptoms (Simpson and Angus rating) occurred statistically significantly more frequently and were more severe during haloperidol than during remoxipride CR treatment despite a statistically significantly higher concurrent use of anticholinergic drugs in the haloperidol group.

IntroductionEven though is rarely, mandibular fracture after the extraction of third molars can occur in almost 1% of the procedures. Gender, age, position of third molar, tooth volume, bone fragility, systemic disorders, associated lesions, and degree of mandibular atrophy are factors that contribute to increase the incidence of fracture. The installation of the titanium miniplate during exodontia is an important tool to prevent the fracture.Presentation of caseThe objective of this study is to present a clinical case of extraction of inferior impacted third molar, in atrophic mandible, with posterior installation of titanium miniplate, to prevent mandibular fracture.Discussion and conclusionpreventive installation of titanium miniplate was effective and indeed prevented the mandibular fracture. No trans-operative or immediate post-operative complications were observed. Post-operative follow-up was of three years, with no complications, showing the success of the procedure.

A Internet tem facilitado as pessoas do mundo inteiro a se comunicar, encontrar pessoas e se reunirem em grupos, tendo como base uma rede ampla de interesses culturais e afiliaes sociais. Tais grupos receberam a denominao de comunidades virtuais ou online e so construdos atravs de interesses sociais e polticos comuns. O presente trabalho trata de uma pesquisa que analisa os comportamentos e as razes de resistncia Globo em comunidades virtuais. Existem centenas dessas no site de relacionamento Orkut. Foram escolhidas e investigadas as cinco comunidades com o maior nmero de membros. Para cumprir tal objetivo foi escolhida a netnografia como meio de investigao do comportamento dos participantes dessas comunidades, em que dados foram copiados de fruns das comunidades virtuais, e a partir das observaes das interaes nas comunidades e da anlise do discurso, foram identificados cinco motivos para a resistncia organizao e o ciberativismo.
