introduction: port wine stains (pws) are congenital vascular malformations. pulsed dye laser (pdl) is the treatment of choice till now, although many lesions do not respond completely. one of possible options is long pulsed alexandrite laser. some literatures confirmed its efficacy. the aim of the present study is to determine the efficacy of this laser as an option in treating refractory pws i...

vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...

purpose : to report clinical and pathologic result of a young patient with isolated cavernous hemangioma of conjunctiva case report : a 26-year-old man who presented with smooth, red, lobular surface mass was seen in the bulbar conjunctiva in temporal side with engorged episcleral and conjunctival vessels around the lesion. excisional biopsy was performed. pathologist confirmed the diagnosis of...

BACKGROUND Pyrophosphate (PPi) is a potent inhibitor of vascular calcification and may be deficient in renal failure. We sought to determine whether plasma PPi is affected by dialysis or the mode of dialysis and whether it correlates with vascular calcification. METHODS PPi was measured in plasma samples stored from a recent study of vascular calcification in 54 HD patients, 23 peritoneal dia...

Background and aim: Lichen planus (LP) is a chronic inflammatory disease with an uncertain pathogenicity. Recent reports have revealed that angiogenesis is effective in the pathogenesis and biologic behavior of lesions. Considering the limitations of the studies related to angiogenesis in oral LP (OLP) and the controversial results, the present study aimed to compare the expression of vascular ...

BACKGROUND Cardiovascular magnetic resonance (CMR) of the vessel wall is highly reproducible and can evaluate both changes in plaque burden and composition. It can also measure aortic compliance and endothelial function in a single integrated examination. Previous studies have focused on patients with pre-identified carotid atheroma. We define these vascular parameters in patients presenting wi...

Endothelin-1 (ET-1) could play a role in the regulation of aldosterone secretion of the human adrenal gland. The presence of the endothelin-converting enzyme 1 (ECE-1) and ET-1 suggests that there is a local ET system in the adrenal cortex, but the in situ synthesis of ET-1 remains to be confirmed. The cellular distribution of the whole ET system was evaluated in 20 cases of aldosterone-produci...

hemangioma of the ovary is reported in a 66 years old woman. vascular tumors of the female genital tract are rare, especially those of the ovaiy. most cases are discovered incidentally. the case presented here was missed clinically.

Careful preoperative evaluation of patients undergoing vascular surgical intervention holds great significance since this group of patients has almost the highest percentage of accompanying diseases with poor outcome. It is well-known that vascular disease – irrespectively of its manifestation – is a generalized disorder, the majority of patients with vascular disease smoke and have chronic pul...

BACKGROUND Vascular progenitor cells (VPCs) are a heterogeneous population, containing a subpopulation co-expressing both endothelial and smooth muscle phenotypes. This study sought to determine whether the level of this subpopulation correlated with the coronary Gensini score. METHODS AND RESULTS VPCs were cultivated in 50 patients undergoing coronary angiography. A subpopulation of VPCs exp...
