Neuromuscular disorders in the background of critical illness are under diagnosed. Standardized screening for weakness in the intensive care unit (ICU) setting is uncommon and persistent weakness as a sequel of critical illness is usually not recognized by physicians in the ICU for whom survival from acute illness is the primary outcome. The spectrum of illness ranges from isolated nerve entrapment with focal pain or weakness, to disuse muscle atrophy with mild weakness, and to severe myopathy or neuropathy with associated severe, prolonged weakness. This update focuses on neuromuscular disorders occurring in the critical care set up associated with diffuse and severe weakness.

Review Case ReportsConcomitant choroid plexus papillomas involving the third and fourth ventricles: A case report and review of the literature.
Choroid plexus papillomas (CPP) are histopathologically benign and rare central nervous system (CNS) neoplasms arising from the epithelium of the choroid plexus. The most common site of presentation of these lesions is in the fourth ventricle in adults and lateral ventricles in children. Third ventricular CPP are uncommon. ⋯ Concomitant CPPs may be secondary to mere coincidental tumor occurrence or to biologic seeding of cerebrospinal fluid (CSF) from a primary CPP despite otherwise benign histopathology. The primary treatment for CPP is surgical resection. Post-operative chemotherapy or radiation for CPP is of controversial benefit.

Neuron-specific enolase and tau protein as neurobiochemical markers of neuronal damage are related to early clinical course and long-term outcome in acute ischemic stroke.
Analyses of neuron-specific enolase (NSE) and tau protein in patients with hyperacute ischemic stroke, their association with infarct volume, severity of the neurological deficit, the neurovascular status and functional outcome. ⋯ Release kinetics of NSE and tau protein are associated with patients' clinical deficits and infarct volume, and may be used as an additional predictor of the early course and functional outcome.

We report the case of a 20-year-old man with a gunshot injury as an example of spontaneous migration of a metallic foreign body within the brain. Computed tomography (CT) showed the bullet in the left temporoparietal region. At 10 days follow-up, CT revealed that the bullet had migrated posteriorly, due to the effect of gravity, lodging in the occipital lobe. Although there are a few literature reports of spontaneous migration of a bullet within the brain, this case was unique as the patient was fully conscious without any neurological deficit.
