Analgésicos Tópicos

Background and objectives: Pain treatment involves the usage of common and opioid analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs) and adjuvant analgesics. Traditionally, these drugs are administered systemically or into the neuraxis. However, when analgesics are applied through these pathways, they are associated with significant side effects, which can hinder its use. Topical administration of analgesics is an alternative. The objective of this paper is to discuss topical analgesics, the mechanisms of action and clinical efficacy. Content: This is a review paper addressing the usage of the topical local anesthetics: capsaicin, clonidine, tricyclic antidepressants, ketamine, opioids and cannabinoids, discussing mechanism of action and effectiveness. Conclusions: Topical analgesics are promising as a strategy for pain treatment, as they are associated with lower incidence of side effects. The benefit of local anesthetics, NSAID's and capsaicin is well established. However, the efficacy of clonidine, tricyclic antidepressants, ketamine, opioids and cannabinoids is still questionable. Studies have shown that the multimodal approach is an alternative, but studies are needed to confirm this hypothesis. © 2012 Elsevier Editora Ltda.

Paradigmas diversos no campo da assistência social e seus estabelecimentos assistenciais típicos

In order to understand what is the situation of entities that serve children and adolescents today, as well as the institutional plot that comprises these institutions, we aimed to formulate a set of paradigmatic possibilities that would allow us to understand the configuration of the dialectical field of various pulses, in which these entities are located. We detected the subjects we associate with counterparts paradigms of Charity, of Human Promotion, of Philanthropy, of assistentialist government patronage, of Social Work as a State Policy, and finally, another set of events that we propose to designate as the paradigm of Citizen Subjects we associate with the ethical perspective of People Education. These paradigmatic possibilities range from the simply various and contrasting ones, including the similar and competing ones, to the dialectically contradictory ones. Its spectrum oscillates between tutelage and citizenship. The characterization of these didactic paradigms can provide us a compass that is required in a highly complex social field, allowing us to understand the variety of ethical effects promoted by these paradigms in the social field.

Estudo duplo cego com Isoconazol e Terbinafina tópicos no tratamento de um paciente com Tinea nigra plantaris bilateral e sugestões para novos diagnósticos diferenciais

The authors report a case of bilateral Tinea nigra plantaris treated through a double-blind study with the topical antifungal agents Isoconazole and Terbinafine. The objective of the study was to clinically compare the efficacy of these two topical antifungal agents on days 10, 20 and 30 of the treatment. No significant clinical differences were found, as all the plantar lesions regressed completely by the end of the treatment. Our conclusion was that in the case reported, the topical antifungal agents Isoconazole and Terbinafine demonstrated identical efficacy as a clinical cure. We also suggest the inclusion of injuries caused by arthropods of the Diplopoda Class in the differential diagnosis of Tinea nigra plantaris, due to the persistent acral hyperpigmentation.
