Involvement of respiratory muscles is a nearly constant feature of neuromuscular disorders, leading to respiratory failure. A careful respiratory follow up adapted to the variable time course of each disease is therefore mandatory. As the first step, a systematic clinical evaluation is essential to detect the subtle respiratory symptoms and signs related to respiratory muscle failure. ⋯ A screening nocturnal oxymetry is useful to detect sleep apneas and hypoventilation. Criteria defining significant desaturations remain however controversial. Suspicion of obstructive sleep apnea syndrome on clinical grounds or oxymetry findings should be confirmed by a conventional polysomnography.

Glioma is seldom diagnosed during pregnancy. In this situation management presents difficult problems for both neuro-oncologists and obstetricians. We report four cases and discuss the management of this unusual situation. ⋯ The management of gliomas diagnosed during pregnancy should not be different from the standard management of gliomas in young non-pregnant adults. Pregnant women because of their young age can have a long survival. Their pregnancy should not prevent them from receiving the best treatment for their glioma. Treatment will depend upon clinico-radiological presentation, histology, gestational age and the patient's desires. Generally speaking, surgical resection of high-grade gliomas should not be delayed during pregnancy. Progress in anesthesia and neurosurgery have greatly reduced the risks for the foetus. After delivery, if the delay between surgery and delivery is too long it is possible to begin cerebral radiotherapy during pregnancy. After the first trimester of gestation this treatment can be given without any important risks for the child.

The influence of pregnancy in multiple sclerosis (MS) has been a matter of controversy for a long time. Women with MS were often discouraged to envisage pregnancy. The Pregnancy in Multiple Sclerosis (PRIMS) study was the first large-scale prospective study aimed at assessing the possible influence of pregnancy and delivery on the clinical course of MS. ⋯ It seems unwise therefore to use this kind of model to select women that would benefit from a putative preventive therapy. The PRIMS study had other major consequences: it fostered the development of specific therapeutic strategies to prevent post partum relapses (IV immunoglobulins, IV methylprednisolone), and suggested a potential role of sexual hormones in the natural history of MS during pregnancy and the post partum, therefore identifying them as a preferential target for prevention. The preventive effect of progesterone combined with estradiol on post partum relapses will be tested in a large-scale randomized and placebo-controlled European trial, the POPART'MUS study.

Although wasp stings can cause local reactions such as pain, flare, edema, swelling and severe reactions, including anaphylaxis; neurological vascular complications are rare. ⋯ It would thus be important to ask patients about any recent wasp sting, in order to provide appropriate treatment.

In third cranial nerve palsy, the lack of mydriasis evokes a noncompressive mechanism. Case report. We report a case of a slightly painful, pure extrinsic third-nerve palsy, complete except for the partial ptosis secondary to the compression by an intracavernous carotid aneurysm. Percutaneous endovascular embolization was followed by complete regression of the palsy within 4 weeks. The pupil may have been spared by the mechanism of compression after the separation of the pupillomotor and extrinsic fibers or the ischemia of the third nerve by its arterial trunk lesion. ⋯ This case report underlines that brain radiological explorations are necessary in some third-nerve pupil-sparing palsies.
