Background:This study was designed to evaluate the role of epidural methadone-lidocaine in cancer pain combined or not to epidural dexamethasone.Methods:In all, 72 cancer patients, 32- to 67-year-old were randomized to six groups (n=12) and prospectively studied to examine analgesia and adverse effects for 3 weeks. Patients received single-dose protocol epidural test drugs: Control group (CG) received epidural 40-mg lidocaine diluted to 10-ml volume with saline. Dexamethasone group (DG) 40-mg lidocaine plus 10-mg dexamethasone. The 2.5MetG 2.5-mg epidural methadone with 40-mg lidocaine; the 5MetG, 5-mg epidural methadone plus 40-mg lidocaine, the 7.5MetG, 7.5-mg epidural methadone plus 40-mg lidocaine and finally the 7.5Met-DexG, 7.5-mg methadone with 40-mg lidocaine and 10-mg dexamethasone.Results:Groups CG, DG and 2.5MetG were similar regarding analgesia and side effects. Patients from 5MetG and 7.5MetG took 3±1 and 5±1 days, respectively, to restart oral morphine. Patients from 7.5MetDG took 14±2 to restart oral morphine (P<0.001). Daily somnolence and appetite improved in the 7.5MetDG during 2-week evaluation (P<0.005). Fatigue improved for both DG and 7.5MetDG during 2-week evaluation (P<0.005). By the third week of evaluation, all patients were similar.Conclusions:Epidural methadone plus lidocaine resulted in dose-dependent analgesia, further improved by epidural dexamethasone, which also improved fatigue.

Myofascial pain syndrome was observed in 1 of 9 patients after head and neck cancer treatment and a worse QOL was observed among them. Tumor site and neck dissection were found to be risk factors for myofascial pain syndrome.

RESUMO: Pacientes com obstrução biliar extra-hepática apresentam particularidades que os tornam susceptiveis às alterações hemodinâmicas, cardíacas, sistêmicas e renais. Este artigo versa sobre os fatores indutores da função renal pós cirurgia descompressiva da via biliar, da instabilidade vascular, dos distúrbios da hemostasia e da ação dos sais biliares e bilirrubinas envolvidos na patogênese das complicações decorrentes da icterícia obstrutiva.
