Clinical Trial Controlled Clinical TrialPain intensity measurements in patients with acute pain receiving afferent stimulation.
Six different pain rating scales, including a "pain relief scale", were compared in 80 patients suffering acute orofacial pain. Pain intensity measurements were made before and after a 30 min period of afferent stimulation (TENS/vibration and placebo). ⋯ The verbal rating scale did not perform well. The pain relief scale and the numerical rating scale are interesting alternatives to the established visual analogue scale.

Enlargement of the third ventricle and hyponatraemia in aneurysmal subarachnoid haemorrhage.
Hyponatraemia following aneurysmal subarachnoid haemorrhage is associated with an increased risk of cerebral infarction. Whether the development of hyponatraemia was related to enlargement of the third ventricle on the admission CT scan was investigated in a consecutive series of 133 patients who were seen within 72 hours of aneurysmal haemorrhage. ⋯ The significant relationship between enlargement of the third ventricle and hyponatraemia remained after adjustment for the amount of cisternal blood, but not after adjustment for the amount of intraventricular blood. These results suggest that the size of the third ventricle is an important but not the only factor in the relationship between acute hydrocephalus and hyponatraemia in patients with aneurysmal subarachnoid haemorrhage.
