ReviewNeurosarcoidosis: a clinical approach to diagnosis and management.
Sarcoidosis is a rare but important cause of neurological morbidity, and neurological symptoms often herald the diagnosis. Our understanding of neurosarcoidosis has evolved from early descriptions of a uveoparotid fever to include presentations involving every part of the neural axis. The diagnosis should be suspected in patients with sarcoidosis who develop new neurological symptoms, those presenting with syndromes highly suggestive of neurosarcoidosis, or neuro-inflammatory disease where more common causes have been excluded. ⋯ In difficult cases, fluorodeoxyglucose positron emission tomography and gallium-67 imaging may identify subclinical disease and a target for biopsy. Symptomatic patients should be treated with corticosteroids, and if clinically indicated other immunosuppressants such as hydroxychloroquine, azathioprine, cyclophosphamide or methotrexate should be added. Anti-tumour necrosis factor alpha therapies may be considered in refractory disease but caution should be exercised as there is evidence to suggest they may unmask disease.

Significance of admission hypoalbuminemia in acute intracerebral hemorrhage.
Low levels of serum albumin may increase the risk of infections and mortality in critically ill patients. We tested the hypothesis that admission hypoalbuminemia predicted infectious complications and poor outcome in subjects with acute intracerebral hemorrhage (ICH). We analyzed a single center cohort of ICH patients collected between 1994 and 2015. ⋯ Low levels of albumin were also independently associated with higher mortality at 90 days (OR 1.78, 95% CI 1.30-2.44, p < 0.001). In conclusion, early hypoalbuminemia is common and predicts poor outcome in ICH patients. Increased susceptibility to pneumonia and sepsis may be the pathophysiological mechanism underlying this association.

Caregivers of patients with amyotrophic lateral sclerosis: investigating quality of life, caregiver burden, service engagement, and patient survival.
Few studies in amyotrophic lateral sclerosis (ALS) have profiled disease-specific features of the condition in conjunction with assessment of caregivers' burden, distress, quality of life, and investigated patient survival. Eighty-four ALS patients and their primary caregivers were enrolled. Patients completed ALS-specific measures of physical and cognitive function, while caregivers completed measures of anxiety, depression, caregiver burden, and quality of life. ⋯ However, significant differences were reported on subjective measures of anxiety (p < 0.000), depression (p < 0.001), distress (p < 0.000), and quality of life (p < 0.000). These data demonstrate the limited impact of ALS patient-related variables, i.e., ALSFRS-R and onset, on caregiver burden in ALS, and identify the importance of the psychological composition of caregivers. This study suggests that the subjective experience of individual caregivers is an important factor influencing the severity of experienced caregiver burden.

Characteristics of hypertrophic pachymeningitis in patients with granulomatosis with polyangiitis.
Hypertrophic pachymeningitis (HP) is an important neurologic complication of granulomatosis with polyangiitis (GPA, formerly Wegener's granulomatosis). The aim of this study is to investigate the clinical features, radiological findings, and diagnostic pitfalls of GPA-related HP. A retrospective chart review was performed to screen patients diagnosed with GPA at Samsung Medical Center between 1997 and 2016. ⋯ Patients with HP rarely had neurologic deficits (N = 3, 37.5%). Different clinical or radiologic features may be observed in GPA-related HP. Early recognition and accurate diagnosis of GPA-related HP are needed in addition to neuroimaging findings.

Longitudinal multi-modal neuroimaging in opsoclonus-myoclonus syndrome.
To investigate structural, metabolic, and functional connectivity changes in visual and oculomotor structures in a patient with paraneoplastic opsoclonus-myoclonus syndrome, serial resting-state functional and structural MRI, and FDG-PET data were collected during the acute stage and later on when the opsoclonus had resolved. In the acute stage, an FDG-PET scan demonstrated a substantially increased metabolism in structures around the deep cerebellar nuclei [e.g., fastigial nucleus (FN)] and a relatively reduced metabolism in the bilateral occipital lobes which normalized over 12 months. ⋯ The functional connectivity between the OMV and FN showed a positive correlation during the acute stage, which decreased later on. We provide a descriptive presentation of the changes of abnormal functional connectivity throughout visuo-oculomotor brain areas during opsoclonus and suggest directions for further research on the pathogenesis of opsoclonus.
