[Benign paralysis of the last 4 cranial nerves. Arguments in favor of an ischemic mechanism].

The last four cranial nerves are fed by the ascending pharyngeal artery, a branch of the external carotid artery. The fact that paralysis of these nerves may occur immediately after arteriography of the external carotid artery demonstrates that ischaemic truncular neuropathies do exist. The deficit is sudden and usually regressive. Ischaemia may account for regressive paralysis of these nerves reported in diabetes, herpes zoster and after some traumas. Apparently idiopathic and benign paralysis might be due to the same mechanism. All 4 nerves may be affected, or only the IXth, Xth and XIth nerves, or the XIth nerve may be spared, being fed by two arteries. Apart from the obvious case of arteriographic accident, the diagnosis of paralysis of ischaemic origin can only be made after other causes, notably compression, have been excluded, since direct evidence of arterial obstruction is exceptionally obtainable; regression at follow-up is a major argument in favour of ischaemia.

[Delayed contralateral hemiplegia complicating ophthalmic herpes zoster].

Contralateral hemiplegia may develop a few weeks after the onset of an ophthalmic herpes zoster. This complication, which is not part of the herpetic encephalopathy, generally coexists with lesions of arteritis demonstrable by arteriography, affecting in most cases the proximal segments of the middle and anterior cerebral arteries and resulting in infarcts. The pathophysiology of these lesions is uncertain, but the vessels appear to be invaded by contiguity.

[Meningo-radiculitis following tick bite].

The authors report nine cases of acute inflammatory polyradiculoneuritis developing one to eleven weeks after a tick bite, regressive, painful and asymmetrical, with an albumino-cellular reaction in the CSF. They stress the very particular physiognomy of this type of meningo-radiculitis, its seasonal occurrence and the uncertain nature of its pathogenesis.

[Dexamethasone test in cluster headache].

Cluster headache and manic depressive illness share in common similarities like: periodic symptomatology, accessibility to lithium therapy, abnormalities in circadian rhythm of cortisol. Though, in contrast to periodic depression, D.S.T. was found normal in 9 patients with cluster headache.
