BACKGROUND Osteoarticular disease is universally the most common complication of brucellosis. Sacro-iliac joint (SIJ) is the most frequent osteoarticular location of involvement. Sacroiliitis (SI) usually is associated with acute form of the disease, thus frank SIJ destruction caused by brucellosis is rare. PURPOSE To report the case of a patient(More)
BACKGROUND Assessment of endothelial function can provide essential information about the mechanisms of cardiovascular disease. Emerging data show that erectile dysfunction (ED) can precede the symptoms of ischemic heart disease, and this suggests that endothelial dysfunction is the link between these two clinical entities. OBJECTIVE To evaluate penile(More)
Aging, independently from the hormonal status, is a major risk factor for cardiovascular morbidity in healthy women. Therefore, we studied the effect of healthy aging on the cardiovascular homeostatic mechanisms in premenopausal and postmenopausal women with similar estrogen levels. Twelve healthy postmenopausal women, confirmed by follicular-stimulating(More)
The ability of L-3,4-dihydroxyphenylalanine (L-DOPA) to release noradrenaline (NA) from peripheral and CNS neurons was studied using isolated rat vas deferens and in vivo frontal cortex microdialysis. Application of L-DOPA (30 microM) to vas deferens increased basal NA efflux but not electrical field stimulation-evoked release of NA when the tissue was(More)
The use of a tourniquet to control bleeding is a necessity in both surgical and prehospital settings. Tourniquet application, if performed properly, can be a lifesaving procedure, particularly in a traumatic setting such as the battlefield. A tourniquet is easily applied and requires the use of a relatively uncomplicated piece of equipment. However,(More)
PURPOSE Penile endothelial function (EnF) is 1 of the major factors involved in the pathophysiology of erectile dysfunction. EnF assessment could offer crucial information on the etiology and degree of severity of cavernosal vascular pathology. In the present study we propose a new technique for the evaluation of penile EnF and test its applicability using(More)
OBJECTIVE Local regulatory mechanisms and microvascular function play a major role in the pathogenesis of hemodynamic and trophic changes in patients with complex regional pain syndrome-1 (CRPS). Venoarteriolar and venoarteriolar-myogenic reflexes (VAR, VMR, respectively) as well as endothelial-dependent vasodilatation are important contributors to local(More)
Local vasoconstrictor reflexes, the vascular myogenic response (VMR) and the veno-arterial reflex (VAR) are necessary for the maintenance of regional blood flow and systemic arterial blood pressure during orthostatic stress. Their molecular mechanism is unknown. We postulated that adenosine is involved in the activation of these local reflexes. This(More)
Premenstrual syndrome (PMS) presents with emotional and physical symptoms. Although the emotional symptoms have been extensively studied, the pathophysiology of the fluid-retention symptoms is not currently known. We tested the hypothesis that the fluid regulatory mechanisms are disturbed in PMS. Nine regularly menstruating women with PMS were compared with(More)
PURPOSE Although the effect of phosphodiesterase type 5 inhibitors on endothelial function in the systemic circulation has been extensively studied, its effect on penile endothelial function remains unexplored. Therefore, we evaluated the effect of daily sildenafil on penile endothelial function. MATERIALS AND METHODS A total of 60 patients with erectile(More)
