[Episodic ++paroxysmal hemicrania or chronic paroxysmal hemicrania in pre-chronic state?].

Two women suffered from strictly unilateral, periocular headaches for many years. The clinical characteristics of headaches were those described in chronic paroxysmal hemicrania. However, both patients showed an episodic evolution of pain. In one case, this stage could be considered pre-chronic because it was later followed by the classic and apparently definitive chronic period of the disorder. In the second case the episodic stage persisted all along the evolution of the disease and the headache did not reach the chronic period. The patient has been free of pain without treatment for the last three years. This second observation can be considered as an example of episodic paroxysmal hemicrania. In the episodic cases the response of pain to indomethacin can be difficult to be ascertained.

[Pituitary study in benign intracranial hypertension].

Pituitary function studies were performed on 20 patients with benign intracranial hypertension. Abnormal results were only obtained in six cases and all of these findings could be attributed to sources other than the increased intracranial pressure. Once the disease as well as its cause had disappeared, a second study was carried out and the results for all the patients were then normal. Computerized tomographic scanning of the sella turcica detected an empty sella in one patient and a possible hypophyseal microadenoma without functional repercussions in another. No evidence was found that benign intracranial hypertension is provoked by an impairment in pituitary function, nor that it could be a secondary complication thereof.

[Davidenkow syndrome].

A 31-year-old female had since childhood walking difficulties on her right foot. She subsequently developed a right-sided scapuloperoneal amyotrophy with mild distal sensory sings. Nerve conduction velocities and nerve biopsy showed a peripheral neuropathy, and the case was thought to be an example of Davidenkow's syndrome. At the age of 41, the musculature innervated by the right V, VII, XI and XIIth cranial nerves became impaired and this suggested that the lower motor neuron was also involved precluding this picture from inclusion among the Hereditary Motor and Sensory Neuropathies (HMSN) to which Davidenkow's syndrome has been related.

[Non-paraneoplastic polioencephalomyelitis].

A 60-year-old male presented with cerebellar ataxia and ocular flutter which disappeared after ten months of evolution. The patient later had three other different bouts which caused cerebral, brainstem and polyradiculoneuritis-like symptomatology. The disease evolved in 20 months and at necropsy a primary polioencephalomyelitis was found. The remitting and relapsing course of the disease is better explained by an autoimmune-mediated lesion.

[Prophylactic treatment of episodic cluster headaches with methysergide and prednisone].

In two consecutive series of 25 cases each suffering from episodic cluster headache, one of the clusters was treated prophylactically in the first series with methysergide and in the other with prednisone. The duration of the clusters under treatment was similar in both series. The results of our study suggest that neither the methysergide nor the prednisone were able to shorten the duration of clusters.
