Observational Study
A High-Resolution Analysis on the Meteorological Influences on Spontaneous Intracerebral Hemorrhage Incidence.
To investigate the influence of meteorological factors on the incidence of intracerebral hemorrhage (ICH). ⋯ By using high-quality meteorological data analyzed with a sophisticated and robust statistical method that minimizes the confounding effect of seasonality, no clearly identifiable meteorological influence for the ICH events considered can be found.

Large or giant internal carotid artery (ICA) aneurysms often cause visual deficits and cranial nerve palsy. The aim of this study was to investigate the efficacy of ligation of the ICA with high-flow bypass. ⋯ Early treatment is recommended when the visual and ophthalmologic symptoms are present because treatment delay is a risk factor for nonimprovement of symptoms.

Patients with neurofibromatosis type 2 (NF2) are prone to develop multiple intracranial neoplasms, such as schwannomas of the cranial nerves and meningiomas. The aim of our study was to investigate 1) the median growth rate per year, 2) the growth-free interval, and 3) the growth patterns of NF2-associated intracranial tumors. ⋯ Most NF2-associated tumors display a saltatory growth pattern. Meningiomas and untreated vestibular schwannomas grow rapidly and overall at similar rates. Tumors of the CPA that have been operated on and non-vestibular schwannomas show less relative growth per year.
