Cheiro-oral syndrome is characterized by sensory impairment confined to perioral area and ipsilateral fingers/hand. It results from an involvement of the ascending sensory tracts above the pons. However, a crossed pattern of perioral and acral paresthesia was rarely reported before. ⋯ The crossed cheiro-oral syndrome seems a mild form of Wallenberg's syndrome. Therefore, it predicts medullary involvement and is also a warning sign for progression.

ReviewThe therapy of multiple sclerosis with immune-modulating or immunosuppressive drug. A critical evaluation based upon evidence based parameters and published systematic reviews.
Today many different drugs are available for treatment of multiple sclerosis (MS). Interferons, glatiramer acetate, mitoxantrone, and natalizumab have been approved by the regulatory authorities of many countries for the treatment of MS. Evidence based medicine (EBM) principles allow physicians to better address the correct treatment for patients. ⋯ Due to its lower efficacy, glatiramer acetate should be used as a second choice in case of intolerable side effects or toxicity of interferon beta. Great efficacy has been demonstrated for mitoxantrone and natalizumab. These drugs should be, however, used with particular attention for their potential toxic effects.

Case ReportsChordoid glioma of the third ventricle attached to the optic chiasm. Successful removal through a trans-lamina terminalis approach.
Chordoid glioma of the third ventricle constitutes a rare, very recently recognized histological entity. Most reports of this neoplasm, focused on its distinct histological features, have hypothesized about a probable origin of the lesion at the third ventricle floor and/or the lamina terminalis. We report on a new case, presenting neuroradiological and intraoperative pictorial evidences of the tumoral attachment, limited to the chiasm-lamina terminalis junction. ⋯ Chordoid glioma should be included in the differential diagnosis of third ventricle tumors. Preoperative neuroradiological suspicion of this lesion should alert the neurosurgeon about the presence of a tight tumoral adherence at the level of the chiasm-lamina terminalis junction. The trans-lamina terminalis approach provides a suitable route for an early control of this attachment under direct vision, allowing a safe dissection of the mass from the third ventricle.

Case ReportsFeasibility and safety of intrathecal nimodipine on posthaemorrhagic cerebral vasospasm refractory to medical and endovascular therapy.
The effectiveness of balloon angioplasty and intra-arterial infusion of vasodilating agents for patients suffering from severe vasospasm following aneurysmal subarachnoid haemorrhage (SAH) is often unsatisfying and there is still demand for further last resort treatment strategies. In the current prospective study, we attempted the intrathecal lavage administration of nimodipine in cases of severe cerebral vasospasm that were refractory to medical and endovascular therapy. ⋯ The present study has for the first time demonstrated the feasibility and safety of intrathecal nimodipine lavage in patients with severe vasospasm resistant to the established medical and endovascular treatment strategies. The results of the study are therefore encouraging, and further experimental and clinical trials should be carried out so as to investigate the efficacy of intrathecal nimodipine lavage in vasospasm therapy.
