Paradoxical brain embolism may not be uncommon-prospective study in acute ischemic stroke.
Proving that right-to-left shunt (RLS) represents the precise causative mechanism in ischemic stroke patients with RLS is difficult. The aim of this study was to examine the frequency and clarify the clinical characteristics of paradoxical brain embolism (PBE). ⋯ Clinical characteristics of PBE are a female preponderance, infarcts affecting both anterior and posterior circulations, and an absence of risk factors.

Hypnic headache is a rare form of primary headache with attacks occurring exclusively with sleep. As it is typical of the elderly, a wide range of alternative diagnosis must be considered. ⋯ We reviewed the literature to evaluate the usual diagnostic workup performed in hypnic headache patients. We suggest that 24 h ambulatory blood pressure monitoring may be included in the evaluation of nocturnal headache complaints especially in the elderly, in whom essential hypertension is a very frequent comorbidity.

Vitamin D levels in people with multiple sclerosis and community controls in Tasmania, Australia.
Adequate 25(OH)D levels are required to prevent adverse effects on bone health. Population-based data on factors associated with 25(OH)D levels of people with MS have been lacking. ⋯ The strong associations between disability, sun exposure and vitamin D status indicate that reduced exposure to the sun, related to higher disability, may contribute to the high prevalence of vitamin D insufficiency found in this population-based MS case sample. Active detection of vitamin D insufficiency among people with MS and intervention to restore vitamin D status to adequate levels should be considered as part of the clinical management of MS.
