Because of distinct pain symptoms in the presence of an ascending partial paralysis-Brown-Sequard Syndrome-from T 5/6 upward in a 56-year-old patient, therapy with paravasalic injections of bupivacaine 0.125% in the area of the femoral artery (right) was given. The patient kept a pain diary with entries every 2 h for 61 weeks. Evaluation of the documentation demonstrates the success of the therapy and shows the possibilities of different kinds of evaluation of well-documented pain data.

Cervicogenic headache: anesthetic blockades of cervical nerves (C2-C5) and facet joint (C2/C3).
In a series of 14 patients with cervicogenic headache, cervical nerve blockades (C2-C5 and facet joint C2/C3) have been carried out in order to elucidate possible underlying mechanisms and to evaluate the diagnostic potential of these procedures. Blockade of the C2 nerve resulted in freedom from pain in 5 of 10 patients and seemed to be the most informative procedure. ⋯ C4 and C5 nerve blockades are probably of little value in the work-up of such patients. When evaluating the C2/C3 facet joint injection, one has to take possible leakage of anesthetic agent from the joint into consideration, since the third occipital nerve which runs close to the facet joint may be anesthetized through the leakage.

Case Reports
Caudal blockade in the management of aortic thrombosis following umbilical artery catheterisation.
A neonate, with a postconceptual age of 29 weeks, suffered thrombosis of the aorta as a consequence of umbilical artery catheterisation. This resulted in ischaemic lesions of the lower limbs and buttocks. Part of the management consisted of the insertion of an extradural catheter, via the caudal route, which provided good pain relief and may have improved lower limb blood flow.
