seasonal and diurnal variations of aneury-smal subarachnoid hemorrhage

Seasonal and Diurnal Variations of Aneurysmal Subarachnoid Hemorrhage

The seasonal and diurnal variations in the incidence of hypertension, cerebrovascular accident, coronary heart disease were well documented, but the relation between season and daytime on the onset of aneurysmal subarachnoid hemorrhage (ASAH) was a subject of controversy. In the present study we aimed to evaluate the role of season of year and diurnal changes on the onset of ASAH. The time was ...

Seasonal and diurnal variations of particulate nitrate and organic matter

Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Nitrate and several organic compounds such as dicarboxylic acids (e.g. succinic acid, glutaric acid), Polycyclic Aromatic Hydrocarbons (PAHs) or n-alkanes form the group o...

Seasonal and diurnal variations of Hg over New England

Factors influencing diurnal to interannual variability in Hg over New England were investigated using multiyear measurements conducted by AIRMAP at the Thompson Farm (TF) coastal site, an inland elevated site at Pac Monadnock (PM), and two month measurements on Appledore Island (AI) in the Gulf of Maine. Mixing ratios of Hg at TF showed distinct seasonality with maxima in March and minima in Oc...

Cardiac Complication Following Subarachnoid Hemorrhage

Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...

Subarachnoid Hemorrhage.

Aneurysmal subarachnoid hemorrhage (SAH) is a neurological emergency with high risk of neurological decline and death. Although the presentation of a thunderclap headache or the worst headache of a patient's life easily triggers the evaluation for SAH, subtle presentations are still missed. The gold standard for diagnostic evaluation of SAH remains noncontrast head computed tomography (CT) foll...
