We present a case of super-refractory status epilepticus secondary to anti-NMDAR encephalitis treated with emergent resective surgery. CASE STUDY A 7 years-old boy presented with progressive abnormal irritability. On the day after(More)
PURPOSE To compare the mydriatic efficacy and cardiovascular safety of the mydriatic options. METHODS This was a prospective randomized analysis of 90 eyes submitted to senile cataract surgery. Group A (30 eyes) included topical mydriasis, group B (30 eyes) included mydriasis with the ophthalmic insert (Mydriasert), and group C (30 eyes) included(More)
BACKGROUND Neuromyelitis Optica (NMO) is an inflammatory demyelinating disease of the CNS. There have been few epidemiologic studies on NMO, none in Portugal. OBJECTIVE To analyze the clinical, biological and MRI characteristics from a cohort of Portuguese patients who fulfilled the Wingerchuk 2006 NMO/NMOSD criteria. To identify and characterize those(More)
Parkinsonian features have been described in patients with POLG1 mutations. Notwithstanding, the clinical expression has been revealed heterogeneous and the response to dopaminergic treatment has been document in few cases. We aim to describe the longitudinal clinical features and the treatment response of three unrelated patients with neurodegenerative(More)
