Conclusion: Esophagectomy after prior anti-reflux surgery is chal

Conclusion: Esophagectomy after prior anti-reflux surgery is challenging, but the stomach is usually a suitable conduit for esophageal replacement. Patients with a history of anti-reflux surgery who undergo esophagectomy are at significantly increased risk for postoperative complications, anastomotic leak, selleck and need for reoperation.

“The present study examined the role of dopamine and D(1)-and D(2)-like dopamine receptors in ventrolateral orbital cortex (VLO)-evoked anti-hypersensitivity in a rat model of neuropathic pain, as well as the possible underlying mechanisms.

Results showed that microinjection of apomorphine [(R(-)-apomorphine hydrochloride)], a non-selective dopamine receptor agonist,

into the VLO attenuated spared nerve injury (SNI)-induced mechanical allodynia in a dose-dependent manner. This effect was completely blocked by the D(2)-like dopamine receptor antagonist S(-)-raclopride(+)-tartrate salt (1.5 mu g), but was enhanced by the D(1)-like dopamine receptor antagonist SCH23390 (R(+)-SCH-23390 hydrochloride, 5.0 mu g). The attenuating effect of apomorphine on mechanical allodynia was mimicked by application of the D(2)-like dopamine receptor agonist quinpirole [((-)-quinpirole hydrochloride, 0.5, 1.0, and 2.0 mu g)]. In addition, microinjection of larger doses (10 and 20 mu g) of SCH23390 SCH 900776 into the VLO significantly attenuated allodynia. Furthermore, microinjections of GABA(A) receptor antagonists, bicuculline [(+)-bicuculline, (S), 9(R)] and picrotoxin (200 and 300 ng for both drugs), into the VLO attenuated mechanical allodynia. A small dose. of bicuculline or picrotoxin (100 ng) resulted in increased quinpirole (0.5 mu g)-induced anti-allodynia. In contrast, GABA(A) receptor agonists, muscimol hydrochloride (250 ng) or THIP [(2,5,6,7-retrahydroisoxazolo(5,4-c)pyridine-3-ol

Flucloronide hydrochloride, 1.0 mu g)], blocked quinpirole (2.0 mu g)-induced attenuation. These results suggest that the dopaminergic system is involved in mediating VLO-induced anti-hypersensitivity, activation of D(2)-like dopamine receptors, and inhibition of D(1)-like receptors resulting in anti-hypersensitivity. In addition, the mechanisms of GABAergic disinhibition might be involved in D(2)-like receptor mediating effects in neuropathic pain. (C) 2010 IBRO. Published by Elsevier Ltd. All rights reserved.”
“Objective: Video-assisted thoracoscopic lobectomy remains controversial. We compared outcomes from participants in a randomized study comparing lymph node sampling versus dissection for early-stage lung cancer who underwent either video-assisted thoracoscopic or open lobectomy.
