Osteopathic manipulative treatment is effective on pain control associated to spinal cord injury.

STUDY DESIGN: This study was designed as an experimental study (trial). OBJECTIVES: To verify the effects of the association between conventional pharmacological treatment and osteopathic manipulative treatment (OMT) for chronic pain management in spinal cord injury (SCI). SETTING: This study was carried out at Spinal Unit, Ospedale Niguarda Ca' Granda, Milan, Italy. Istituto Superiore di Osteopatia, Milan, Italy. METHODS: We enrolled 47 patients with SCI, 26 with pain of both nociceptive and neuropathic origin, and 21 with pure neuropathic pain. In all, 33 patients had a complete spinal cord lesion (ASIA level A) and 14 had incomplete lesion (ASIA level B, C and D). The patients were subdivided in a pharmacological group (Ph), a pharmacological osteopathic (PhO) group and a osteopathic (Os) group. The verbal numeric scale (VNS) was used at various time intervals to evaluate treatment outcomes. RESULTS: Ph patients reached a 24% improvement in their pain perception, assessed by the VNS scale after 3 weeks of treatment, whereas Os patients reached a 16% improvement in their pain perception for the same weeks. Both treatments per se failed to induce further improvements at later time points. In contrast, the combination of the two approaches yielded a significantly better pain relief both in patients with nociceptive or pure neuropathic pain in the PhO group. CONCLUSIONS: Our results suggest the OMT is a feasible approach in patients in whom available drugs cannot be used. Moreover, a benefit can be expected by the association of OMT in patients treated according to existing pharmacological protocols.

In vitro and in vivo antitumor efficacy of docetaxel and sorafenib combination in human pancreatic cancer cells.

The response of pancreatic cancer to treatments remains unsatisfactory, highlighting the need for more effective therapeutic regimens. Sorafenib, an orally available multikinase inhibitor, is active against different tumors, including pancreatic cancer. We studied the antitumor efficacy of sorafenib in combination with different antitumor drugs currently used in clinical practice in in vitro and in vivo experimental models of human pancreatic cancer. The cytotoxic effect of sorafenib and conventional antitumor drug combinations was evaluated in vitro in human pancreatic cancer cell lines and the efficacy of the most active combination was tested on tumor-bearing mice. Flow cytometric, Western blot and immunohistochemistry analyses were performed to investigate the mechanisms involved in the activity of single drugs and in their interaction when used in combination. Sorafenib showed a strong sequence-dependent synergistic interaction in vitro with docetaxel, which was highly dependent on the drug sequence employed. In vivo, human pancreatic cancer-xenografted mice treated with docetaxel followed by sorafenib reduced and delayed tumor growth, with complete tumor regression observed in half of the mice. This marked antitumor effect resulted in an overall increase in mouse survival of about 70% and in a complete cure in 3 of the 8 treated mice. The strong activity was also accompanied by marked apoptosis induction, inhibition of tumor angiogenesis and downregulation of ERK signalling. Our results show that the docetaxel and sorafenib combination exerts high therapeutic efficacy in experimental models of human pancreatic cancer, indicating a promising antitumor strategy for clinical use.
