Minimally invasive posterior percutaneous transarticular C1-C2 screws: how I do it.

Background: Transarticular C1-C2 screw fixation, first described by Magerl, is a widely accepted used technique for C1-C2 instability with a good biomechanical stability and fusion rate.

Method: We present a 69-year-old woman, who was diagnosed with a C2 Odontoid fracture type III and primarily treated with conservative treatment and collar. During first 2 weeks of follow-up, the patient developed cervical pain associated with C1-C2 instability.

An exceptional presentation of pituicytoma apoplexy: A case report.

Pituicytomas are a rare form of indolent neoplasms, which typically present with visual disturbance and hypopituitarism. Complete resection by a trans-sphenoidal approach is the optimal treatment. Only 80 cases have been described thus far in the current literature and the present case is the first to describe the development of pituitary apoplexy in the context of a pituicytoma.

Comparison of Complications in Patients Receiving Different Types of Intracranial Pressure Monitoring: A Retrospective Study in a Single Center in Switzerland.

Objective: Intracranial pressure (ICP) monitoring has become "state of the art" in the management protocol for unconscious or sedated patients with intracranial pathologies; however, all current monitoring systems have significant drawbacks. We analyzed the complications of these monitoring devices as well as the risk factors for those complications.

Methods: We reviewed a total of 288 patients with ICP monitoring, i.

Bilateral ptosis: Lesion in the oculomotor nuclei or supranuclear lesion?

Background: Bilateral ptosis is a very interesting clinical challenge for doctors because of the multiple possible localizations of a lesion which can lead to this neurological sign.

Objectives: Through this case report, we aim to determine the difference between an apraxia of lid opening (ALO) with difficulty in initiating the act of lid elevation, in spite of adequate understanding, motor control and cranial nerve pathways, and a bilateral ptosis with a lesion in the oculomotor nucleus or blepharospasm.

Methods: The case report of a 50-year-old patient presenting bilateral ptosis and multiple ischemic lesions in the brainstem and bilateral frontal lobe lesions after the emergency removal of a large frontal tumor.
