[High performance of an implantable Holter monitor in the detection of concealed paroxysmal atrial fibrillation in patients with cryptogenic stroke and a suspected embolic mechanism].

Introduction: Implantable loop recorders (ILR) may allow detection of occult paroxysmal atrial fibrillation (PAF) in patients with cryptogenic ischemic stroke. However, optimal selection algorithm and ideal duration of monitoring remain unclear. AIM.

[Hemicrania continua: characteristics and therapeutic experience in a series of 36 patients].

Introduction: Hemicrania continua is characterised by a continuous unilateral pain, which frequently gets worse in association with autonomic symptoms. It is probably little known and underdiagnosed. Its diagnosis requires a response to indomethacin, which is not always well tolerated.

[Epicrania fugax: the clinical characteristics of a series of 18 patients].

Introduction: Epicrania fugax is a recently reported condition consisting in brief painful paroxysms that begin in the posterior regions of the brain and irradiate towards the ipsilateral eye, nose or temple.

Aims: To present 18 cases of epicrania fugax from a monographic headache centre in a tertiary hospital and to analyse their demographic and clinical features, as well as the indication and response to prophylactic treatment.

Patients And Methods: Between March 2008, when epicrania fugax was first reported, and March 2011, of a total of 1210 patients who were attended in that service (1.

Insulin resistance is associated with a poor response to intravenous thrombolysis in acute ischemic stroke.

Objective: Insulin resistance (IR) may not only increase stroke risk, but could also contribute to aggravate stroke prognosis. Mainly through a derangement in endogenous fibrinolysis, IR could affect the response to intravenous thrombolysis, currently the only therapy proved to be efficacious for acute ischemic stroke. We hypothesized that high IR is associated with more persistent arterial occlusions and poorer long-term outcome after stroke thrombolysis.

[Encephalitis due to antibodies against the NMDA receptor. A case report of a female patient with no associated tumour and a literature review].

Introduction: A severe form of acute encephalitis associated to antibodies against the N-methyl D-aspartate (NMDA) receptor has recently been reported. This clinical picture occurs in young people, not always with an underlying tumour and, despite the initial severity, if identified and treated at an early stage, complete recovery without any kind of sequelae can be achieved. We report on a new case and review the body of knowledge currently available on this recently identified condition.
