Introduction: Compared with the general population, hemodialysis patients are at increased risk of vascular calcification, which in turn is associated with an increased risk of mortality. Regarding the role of vitamin D in bone formation, regulation of calcium, phosphate and iPTH level and correlation of these variables in survival, this study was performed to evaluate the vitamin D serum level...

Vascular anomalies are categorized into vascular tumours or vascular malformations on the basis of clinical features and histopathology. The literature regarding high flow arteriovenous malformations of the auricle is rare. A case of a patient clinically diagnosed with an arteriovenous malformation of the external ear and was managed with preoperative embolization, surgical excision and reconst...

background: subglottic stenosis is defined as inflammatory narrowing of the airway. it can be related to trauma, intubation, autoimmune disorders, vascular malformations, infection and congenital abnormalities. pot-wine stain (pws) is a small dermis venous malformation which is present at birth. pws is found on face and neck, but can occur in throat and can cause subglottic stenosis. case repor...

introduction: klippel–trenaunay syndrome (kts) is a rare congenital mesodermal abnormality characterized by varicose veins, cutaneous capillary malformation, as well as bone and soft tissue hypertrophy. case report: a 2-week-old female infant presented to our clinic because of vascular nevus and progressive enlargement of her right extremities and trunk since birth. the patient was treated with...

inflammation of blood vessels is a characteristic feature of kawasaki disease. neutrophils play a key role in the inflammatory responses where movement of neutrophils toward the site of inflammation depends on cd11b/cd18 expression as adhesion molecules on these cells. the purpose of this study was to investigate cd11b/cd18 expression in patients with kawasaki disease upon diagnosis and after t...

introduction: vascular abnormalities are relatively uncommon lesions, but head and neck is a common region for vascular malformation which is classified as benign tumors. in this paper, the authors report a rare presentation of vascular malformation in the tongue and its managements. case report: an 18 months 2 old child presented with a giant mass of tongue which caused functional and aestheti...

hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...

gastrointestinal (gi) bleeding in pediatric patients has several causes. vascular malformation of the small bowel is a rare disease leading to pediatric gi bleeding. to our knowledge, few reports describe ultrasound and computed tomography findings of venous malformations involving the small bowel. we present a case of long-segmental and circumferential vascular malformation that led to gi blee...

background: type 2 diabetic mellitus patients are amongst the most susceptible groups to vascular abnormalities, which predominantly lead to myocardial disease. the hypercoagulable state has been widely studied by researchers as being the major suspicious mechanism facilitating the consecutive chain of molecular events leading to these complications. however, there is no consensus on the defini...
