Pure sensory stroke as an isolated manifestation of the lateral medullary infarction.

Pure sensory stroke is a common manifestation of a thalamic stroke and may occur less frequently in the infarction of the brainstem, internal capsule, and parietal cortex. The authors report a 47-year-old man who presented with loss of pain and temperature sensation in the left face, arm, trunk, and leg and was found to have a right lateral medullary infarction on diffusion-weighted magnetic resonance imaging. To the authors' knowledge, this is the first case describing pure sensory stroke as a single, isolated manifestation of the lateral medullary infarction that was detected by diffusion-weighted magnetic resonance imaging.

Nonvasculitic autoimmune inflammatory meningoencephalitis.

Caselli and colleagues described five cases with encephalopathy, progressive cognitive decline, ataxia, abnormal CSF studies and steroid responsiveness, and proposed the term non-vasculitic autoimmune inflammatory meningoencephalitis (NAIM). Many of these cases had brain biopsy showing mild leptomeningeal perivascular lymphocytic inflammation, however, none of the cases had a post-mortem. Nonvasculitic autoimmune mediated meningoencephalitis has been described in patients with Sjogren's syndrome, systemic lupus erythematosus and, more recently, with Hashimoto's disease.

Perioperative management of patients with neurologic disease.

Because many of the perioperative problems of the neurologic patient are predictable, they should be anticipated by the neurologist so that measures can be taken to prevent as many complications as possible and to recognize and manage those that cannot be prevented in a timely, efficient manner.

Gait disorders.

Background: Disorders of gait and mobility are common neurologic abnormalities of aging and can have disastrous consequences. Etiology is multifactorial, and normal age-related changes are difficult to distinguish from those resulting from the disease.

Review Summary: Gait evaluation with special techniques provides scientific understanding of physiologic mechanisms, but experienced clinicians can make diagnoses based on general medical and neurologic history and physical examination.

Occipital condyle syndrome.

Objective: Review the clinical features of occipital condyle syndrome.

Background: Occipital condyle syndrome consists of unilateral occipital region pain associated with ipsilateral 12th cranial nerve paresis. It is typically due to metastasis to the skull base and is underdiagnosed.
