The onset of nonpulsatile cardiopulmonary bypass is known to deteriorate microcirculatory perfusion, but it has never been investigated whether this may be prevented by restoration of pulsatility during extracorporeal circulation. We therefore investigated the distinct effects of nonpulsatile and pulsatile flow on microcirculatory perfusion during on-pump cardiac surgery. Patients undergoing co...
Sickle cell disease (SCD) is characterized by microvascular occlusion mediated by adhesive interactions of sickle erythrocytes (SSRBCs) to the endothelium. Most in vitro flow adhesion assays measure SSRBC adhesion during continuous flow, although in vivo SSRBC adhesive interactions occur during pulsatile flow. Using a well-plate microfluidic flow adhesion system, we demonstrate that isolated SS...
Pulsatile tinnitus usually means a turbulent flow within the vessels. We describe a 54-year-old man with a disabling objective pulsatile tinnitus due to a diverticulum of the sigmoid sinus toward the ipsilateral mastoid. We performed a surgical intervention via the endovascular route using coils to obliterate the diverticulum and a stent to avoid coil migration . The patient had a complete and ...
OBJECTIVES Amoxicillin and clarithromycin have been proven to be effective in the treatment of community-acquired pneumonia. This study investigated the in vivo bactericidal efficacy of a novel, pulsatile dosing strategy for amoxicillin and clarithromycin, when used as monotherapy and combination therapy. METHODS A neutropenic murine pneumonia model was used to assess the bactericidal activit...
The transition between puberty and adulthood is accompanied by a slowing in linear growth. Although GH is a key factor that drives somatic development into adulthood, early adulthood coincides with a reduction in circulating levels of GH. To this extent, a pathological decline in postpubertal GH secretion is detrimental to attainment of peak lean muscle mass and bone mass and promotes adiposity...
Pulsatile scrotal masses are extremely rare. We report the first case of pulsatile and painful scrotal mass that had an arterial collateral circulation, equivalent to an arterioarterial shunt, feeding an excluded internal iliac artery aneurysm after aortobifemoral bypass surgery.
