Spontaneous intracranial hypotension: from cerebral venous thrombosis to neurosurgical treatment: a case series experience from a Brazilian tertiary health care center.

Background: Spontaneous intracranial hypotension (SIH) is a secondary cause of headache and an underdiagnosed disease. The clinical presentation can be highly variable. It typically presents with isolated classic orthostatic headache complaints, but patients can develop significant complications such as cerebral venous thrombosis (CVT).

Bone marrow cells are able to increase vessels number during repair of sciatic nerve lesion.

The aim of this study was to compare the outcomes of nerve autografts (GRF) and venous grafts containing mononuclear bone marrow cells (BMCs) in sciatic nerve-lesioned rats. Control animals underwent sham operations (SHAM), received empty venous grafts (EPV), or received venous grafts containing BMC vehicle (AGR). Outcome was evaluated through sciatic functional index (SFI), morphometric and morphologic analyses of the nerve distal to the lesion, and the number of spinal cord motor neurons positive for the retrograde tracer, Fluoro-Gold.

Moving ear syndrome: the role of botulinum toxin.

We report a 30-year-old man with moving ear syndrome caused by focal myoclonic jerks of the right temporal muscle. This focal myoclonus would disappear while the patient was sleeping, swallowing, or speaking. He was treated with botulinum toxin type A with a favorable outcome.
