Background: A fatal outcome occurs in 2% of patients with Reversible Cerebral Vasoconstriction Syndrome (RCVS). Due to its rarity, guidelines for the management most severe forms RCVS are lacking. Case presentation: Here, we describe case a 55 year-old woman who died from complications and reviewed reported literature. In our patient, first episode neurological deterioration was preceded by an ...
Prostanoids derived from arachidonic acid (AA) have been shown to play a permissive role in the regulation of vascular tone and wall tension. Conventionally, epoxyeicosatrienoic acids (EETs) and prostacyclin have been considered as dilatators, whereas thromboxane (TX) and hydroxyeicosatetraenoic acid (HETE) were considered as vasoconstrictors. However, the role of these prostanoids in the media...
I AHPR = acute hypoxic pressor response T he pulmonary circulation responds to acute hypoxia with increases in pulmonary artery pressure and vascular resistance. This acute hypoxic pressor response (AHPR) is a unique physiologic feature distinguishing the pulmonary from the systemic circulation which dilates in response to hypoxia.’ Since Von Euler and Liljestrand described the phenomenon of ac...
Reflex vasoconstriction is attenuated in aged skin due to a functional loss of adrenergic vasoconstriction. Bioavailability of tetrahydrobiopterin (BH4), an essential cofactor for catecholamine synthesis, is reduced with aging. Locally administered BH4 increases vasoconstriction through adrenergic mechanisms in aged human skin. We hypothesized that oral sapropterin (Kuvan, a pharmaceutical BH4)...
