Limb RIPC decreased EBC 8-isoprostane levels and other oxidative lung injury markers during lung lobectomy. RIPC also improved postoperative gas exchange as measured by PaO2/FiO2 ratio.
Anti-Hu paraneoplastic syndromes are usually associated with an underlying neoplasia, although a few patients who are anti-Hu-positive never develop cancer after long-term follow-up. Tumour therapy remains the mainstay of therapeutic options, and early immune therapy in parallel is advisable. When no tumour is found, immunologically-based therapies are nowadays the only options. Recent studies have shown rituximab associated with the tumour therapy to be effective for some patients with anti-Hu paraneoplastic syndrome. We report a case of a patient with anti-Hu antibodies-associated sensory neuronopathy and gastric pseudo-obstruction without an underlying neoplasia four years after the first manifestation who has achieved sustained improvement for two years after treatment with rituximab. This case report supports the effectiveness of rituximab in these syndromes, even for cases where no underlying neoplasia is demonstrated. Further studies are warranted in order to confirm these preliminary data.
During lung lobectomy, the operated lung is collapsed and oxidative injury occurs, with the levels of markers of oxidative stress increasing simultaneously in exhaled breath condensate and blood during one-lung ventilation. These increases were larger after resuming two-lung ventilation. Increases immediately before resuming two-lung ventilation and immediately after resuming two-lung ventilation were directly correlated with the duration of one-lung ventilation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
