Cervicogenic headache is a relatively common and still controversial form of headache arising from structures in the neck. Cervicogenic headache is a unilateral fixed headache characterised by pain that starts in the neck and spreads to the ipsilateral oculo-fronto-temporal area. The pathophysiology of cervicogenic headache probably depends on the effects of various local pain-producing or eliciting factors, such as intervertebral dysfunction, cytokines and nitric oxide. ⋯ Various therapies have been used in the management of cervicogenic headache. These range from lowly invasive, drug-based therapies to highly invasive, surgical-based therapies. Unfortunately, the paucity of experimental models for cervicogenic headache and the relative lack of biomolecular markers for the condition mean much is still unclear about cervicogenic headache and the disorder remains inadequately treated.

The aim of this investigation was to assess the role that NO plays in the antinociceptive activity of tramadol using a rat model of neuropathic pain. Thirty male Wistar rats weighing 200-250 g were randomly divided into five equal groups. The neuropathic pain model used for the study was chronic constrictive injury (CCI) model. ⋯ L-NA+L-arginine) and Group 5 (i.t. L-NA+L-arginine) when compared to Group 1 (i.p. tramadol only) (p<0.05 for both). The results of this study support the involvement of the L-arginine/nitric oxide pathway in the antinociceptive effect of tramadol in a rat model of neuropathic pain.

Randomized Controlled Trial Comparative Study
[Comparison of effects of the administration of intraperitoneal local anesthetics for postoperative analgesia and prevention of shoulder pain].
Postoperative abdominal and shoulder pain are common complications after laparoscopy. The aim of this study is to compare the effects of intraperitoneal local anesthetics on postoperative abdominal and shoulder pain after laparoscopy. 55 women, physical status ASA I, who were undergoing diagnostic or minor gynecologic surgery, was enrolled to the study. ⋯ Shoulder and abdominal pain was assessed with a visual analogue scale, and any other complications were noted during the first 24 hours after surgery. Shoulder and abdominal pain intensity and frequency were significantly less in the local anesthetic groups than control group, similar between ropivacaine and bupivacaine groups.
