An indirect sign of cervical disc hernia is described, consisting of angulation of the alignment of the spinal apophyses of the cervical vertebrae above the site of the hernia in relation to the alignment of those of the vertebrae situated below the lesion.
The autors describe 3 recent cases of severe ischemic accidents from ergotism affecting different regions. Two of the cases resulted from taking Gynergene (ergotamine tartrate) for a short period, while the other case followed continuous administration of Desernil (Methysergide) for 3 years. The third case was treated at a late stage by continuous peridural anesthesia and various vasodilators without success and led to very severe mutilations in two young women. The third case was treated by continuous infusions of sodium nitropruside (SNP) under hemodynamic control, and recovery was rapid and complete. The value of SNP as an antidote for severe ergotism is discussed, together with its mode of administration, and precautions necessary when prescribing this extremely powerful vasodilator treatment for this indication.

After surgical evacuation of a subdural hematoma there is a constant relationship between the return of the deep veins to the midline, the clinical recovery and the absence of a new subdural collection, even when the anterior cerebral artery remains deviated across the midline.
This paper reports the experience of the authors using facial nerve excitability test in Bell's palsy as a tool to understand better the prognosis in that pathology. The authors made a retrospective study of 222 cases of Bell's palsy, followed by serial facial nerve excitability test. The goal of this study as to define correlations between facial nerve excitability test (N.E.T.) values, the rate and degree of recovery OF PATIENTS PRESENTING A Bell's palsy. Results indicated that incomplete paralysis with a normal N.E.T. forecasts a fast and complete recovery in less than three months. Complete paralysis with a normal N.E.T. also forecasts a complete recovery. Those cases of complete paralysis with an abnormally elevated (greater than 2 m. amp.) N.E.T. lead to unsatisfactory results in 27.7 per cent of patients and of these 66.6 per cent took more than three months to recover if at all. Of the patients with complete paralysis and no response to facial nerve stimulation, 73 per cent showed an unsatisfactory recovery.
