RESUMO O tratamento dos deslocamentos facetários cervicais traumáticos (DFC) é preferencialmente cirúrgico, conforme a literatura pertinente, mas há dúvidas quanto a melhor forma de abordagem da coluna: anterior, posterior ou combinada. Realizamos revisão sistemática para avaliar as indicações da abordagem anterior e da posterior nos DFC. A abordagem anterior permite restaurar a lordose cervical, com menor dor no pós-operatório e menos problemas relacionados a ferida cirúrgica. A abordagem posterior permite redução direta dos deslocamentos, bem como pode resultar em uma fixação biomecanicamente mais robusta. Acessos combinados são usados em casos complexos. Embora ambas possam ser usadas, há alguns pacientes que possivelmente se beneficiem preferencialmente de uma abordagem ao invés da outra, como discutido no presente manuscrito. Cirurgiões de coluna devem ser habilitados a realizar ambos os procedimentos para melhor os resultados do tratamento dos DFC.

ABSTRACT Surgical treatment is well accepted for patients with traumatic cervical facet joint dislocations (CFD), but there is uncertainty over which approach is better: anterior, posterior or combined. We performed a systematic literature review to evaluate the indications for anterior and posterior approaches in the management of CFD. Anterior approaches can restore cervical lordosis, and cause less postoperative pain and less wound problems. Posterior approaches are useful for direct reduction of locked facet joints and provide stronger fixation from a biomechanical point of view. Combined approaches can be used in more complex cases. Although both anterior and posterior approaches can be used interchangeably, there are some patients who may benefit from one of them over the other, as discussed in this review. Surgeons who treat cervical spine trauma should be able to perform both procedures as well as combined approaches to adequately manage CFD and improve patients’ final outcomes.

Neste estudo procuramos validar a escala Iowa-Netherlands Comparison Orientation Scale numa amostra de adolescentes portugueses. Esta escala mede níveis de orientação da comparação social. Participaram no estudo 238 estudantes portugueses, com idades entre os 13 e os 18 anos (M = 15.43, DP = 1.76). Verificou-se que a estrutura da escala estava de acordo com a versão original do instrumento, dividindo-se em duas dimensões com índices satisfatórios de consistência interna: Opiniões e Aptidões. A dimensão Opiniões correlacionou-se positivamente com a Autoestima e o Materialismo, e a dimensão Aptidões apresentou correlações positivas com o Self-comparado, o Materialismo e a Impulsividade na compra. No que diz respeito às diferenças de sexo, as raparigas apresentaram médias superiores na dimensão de Opiniões e os rapazes em Aptidões. Os resultados confirmam a adequação da versão portuguesa da escala para avaliar a tendência para a comparação social em adolescentes.

The aim of this study was to translate and search for validity evidence of Iowa-Netherlands Comparison Orientation Scale for adolescents' Portuguese context. This scale assesses levels of social comparison orientation. Participants were 238 adolescents, with ages between 13 and 18 years (M = 15.43, SD = 1.76). We verified that scale structure was in line with the original instrument version. Two dimensions emerged: Opinions and Abilities, both with satisfactory internal consistency indices. The dimension Opinions correlated positively with Self-esteem and Materialism; Abilities showed positive correlations with Self-compared, Materialism and Impulse buying. Regarding sex differences, girls showed higher mean for Opinions; boys higher mean for Abilities. Our results strengthen the Portuguese scale version adequacy to assess a tendency towards social comparison in adolescents.

Among other applications, Ipomoea pes-caprae is popularly used to treat jellyfish stings, supporting the development of a product for dermatological use. Hydroethanolic spray-dried extract was chosen for the further development of phytomedicines, and a stability-indicative HPLC-UV method was developed and validated for the determination of isoquercitrin and isochlorogenic acids A, B and C. The method was developed using a C18 column (250 x 4.6 mm, 5 µm) with an acetonitrile:water mobile phase at pH 3.0 in a gradient run. The four constituents and other unidentified components of the extract were appropriately resolved without interference of degradation products after stress tests (acid, alkali, neutral, oxidant, photolysis). The method showed linearity in the isoquercitrin concentration range from 5.0-50.0 µg mL-1, with adequate precision (RSD% < 2.5% for the intra- and inter-day studies), accuracy (recovery of 100.0 ± 2.0%), and robustness. Both the herbal drug and spray-dried extract of I. pes-caprae were subjected to stability studies in accelerated and long-term conditions over four months. The samples maintained their characteristics and marker contents (< 10% of variation).
