[Postoperative bed header position after burr-hole drainage of chronic subdural haematoma: systematic review and meta-analysis of randomised controlled trials].

Introduction: Several studies have suggested the possible influence of postoperative bed header position on the risk of symptomatic recurrences and medical complications in patients who have been intervened due chronic subdural haematomas. Nevertheless, this hypothesis has not been assessed by a meta-analysis.

Methods: All randomised controlled trials analysing symptomatic recurrence rates in patients who underwent burr-hole drainage of chronic subdural haematomas, describing postoperative bed header positioning, were included.

Diagnostic accuracy of ultrasound for detecting posterior ligamentous complex injuries of the thoracic and lumbar spine: A systematic review and meta-analysis.

Background: Posterior ligamentous complex injuries of the thoracolumbar (TL) spine represent a major consideration during surgical decision-making. However, X-ray and computed tomography imaging often does not identify those injuries and sometimes magnetic resonance imaging (MRI) is not available or is contraindicated.

Objective: To determine the diagnostic accuracy of the ultrasound for detecting posterior ligamentous complex injuries in the TL spine.

[The influence of climate on the onset of intracranial hemorrhages].

Background: there are not studies exploring the potential role of weather conditions in the incidence of intracranial hemorrhages in Latin America.

Methods: a descriptive study was carried out in an emergency room from Cartagena de Indias (Colombia). Data for all adult patients with intracranial hemorrhage and meteorological variables of the days when intracranial hemorrhages occurred were recorded and compared to with those where not a single case.

[Intracerebral hemorrhages following drainage of chronic subdural hematomas].

Background: postoperative intracerebral hemorrhage after drainage of chronic subdural hematoma is a rarely reported complication; however, its incidence, according to different series may be underestimated.

Case Report: this report presents a 77 year old male patient who, after the drainage of bilateral chronic subdural hematomas, developed an extensive hemorrhage in the thalami, basal ganglia, midbrain and pons, with extension into the ventricles and obstructive hydrocephalus.

Conclusions: compression by extra-axial collection decreases cerebral blood flow on the affected hemisphere and alters its vascular self-adjustment.

[Brain stem compression preceded by trigeminal neuralgia in a patient with vertebro-basilar and bilateral carotid dolichoectasia].

We described a patient who had left trigeminal neuralgia by vertebro-basilar dolichoectasia, who underwent microvascular decompression separating the basilar artery of the trigeminal nerve by interposing a vascular graft piece. Symptoms resolved completely after surgery. Nine years later, he has a recurrence of facial pain associated with rapidly progressive brainstem compressive symptoms.
