Influence of the Length Ratio Between Second and Third Metatarsals After Modified Weil Osteotomy on Clinical Outcomes.

Metatarsalgia is a frequent foot disorder. The objective was to evaluate whether the length ratio between the second and the third metatarsals after Weil osteotomy influences clinical outcomes. This retrospective study included 37 patients (53 feet). Preoperative planning consisted of keeping the second metatarsal greater than or equal to the third metatarsal after Weil osteotomy of the second metatarsal or the second and third metatarsals. Based on postoperative weightbearing and digital AP radiographs after Weil osteotomy, we divided the patients into 2 groups: group 1, the second metatarsal was longer than or equal to the third metatarsal; and group 2, the second metatarsal was shorter than the third metatarsal. We investigated whether there were differences between the groups. In 35 (66%) feet, the second metatarsal was longer than or equal to the third metatarsal (group 1), and in 18 (34%) feet, the second metatarsal was shorter than the third metatarsal (group 2). Postoperative American Orthopaedic Foot and Ankle Society scores were 86.2 and 82.7, respectively (p = .32). Postoperative Visual Analog Scale scores were 1.26 and 1.67, respectively (p = .39). The sample showed 11.3% of transfer metatarsalgia to the third metatarsal. Group 1 had 9% of transfer metatarsalgia, whereas group 2 had 17% of transfer metatarsalgia (p = .40). The presence of a second metatarsal shorter than the third metatarsal, after Weil osteotomy of the second metatarsal or the second and third metatarsals, does not influence outcomes or incidence of transfer metatarsalgia to the third metatarsal.

Dilatação arterial mediada por fluxo na pré-eclampsia / Arterial flow mediated by expansion in preeclampsia

A função endotelial está alterada na pré-eclâmpsia e é um aspecto importante na fisiopatologia deste distúrbio hipertensivo da gestação. Pode ser avaliada mensurando-se a resposta vascular dependente do endotélio induzida pela tensão de cisalhamento promovida pelo fluxo sanguíneo através do vaso. Este artigo tem como objetivo revisar as alterações funcionais encontradas na pré-eclâmpsia, dando ênfase à disfunção endotelial e sua avaliação de forma não invasiva durante a gestação através da ultrassonografia com doppler pela técnica de dilatação mediada por fluxo.

Neuroimagem em paciente com SIDA / Neuroimaging in patients with aids

Este artigo tem por objetivo revisar as principais desordens do sistema nervoso central (SNC) em pacientes HIV positivos e com Síndrome de Imunodeficiência Adquirida (SIDA). Através de exames de neuroimagem serão discutidos os tipos de lesões e seus agentes, assim como suas implicações clínicas.
