Ability of short-time low peep challenge to predict fluid responsiveness in mechanically ventilated patients in the intensive care.

Short-time low PEEP challenge (SLPC, application of additional 5 cmHO PEEP to patients for 30 s) is a novel functional hemodynamic test presented in the literature. We hypothesized that SLPC could predict fluid responsiveness better than stroke volume variation (SVV) in mechanically ventilated intensive care patients. Heart rate, mean arterial pressure, stroke volume index (SVI) and SVV were recorded before SLPC, during SLPC and before and after 500 mL fluid loading.

Extracranial aneurysm of the posterior inferior cerebellar artery.

Aneurysms of the posterior inferior cerebellar artery (PICA) are rare, and may arise in unusual locations due to the complex and variable anatomy of this artery. The PICA does not usually originate from the extracranial vertebral artery. Of the few reported extracranial PICA aneurysms, all affected the distal segment.

The role of exudation in chronic subdural hematomas.

Object: Chronic subdural hematomas (SDHs) are a local inflammatory process that causes the formation of a granulation tissue often referred to as the external or outer membrane. This membrane has abnormally permeable macrocapillaries. Therefore, exudation from the macrocapillaries in the outer membrane of chronic SDH may play an important role in the enlargement of chronic SDH.

Primary solitary cervical amyloidosis: case report and review of the literature.

Study Design: A case report and literature review are presented.

Objective: To describe and review the clinical presentations, characteristic findings from imaging studies, types, differential diagnosis, prognosis, and treatment of amyloidoma arising within the vertebrae.

Summary Of Background Data: Amyloidoma can occur in the bone, skin, larynx, lymph nodes, urinary bladder, eye, tongue, and gastrointestinal system.

Cerebellopontine angle lipoma with extracranial extension.

Lipomas of the cerebellopontine angle (CPA) are rare. A recent literature review identified only 98 reported cases of CPA lipoma. We present here a case of CPA lipoma in a 28-year-old woman who was admitted to our hospital with hearing loss in her left ear.
