In premature birth and postpartum damage to the developing lung, processes of formation pulmonary vessels alveoli are disrupted, leading bronchopulmonary dysplasia (BPD). BPD is a multifactorial disease pathogenesis lung tissue still not fully understood. Studies angiogenesis biomarkers can be informative for assessing development BPD. this study we examined blood serum 65 infants aged 6 180 da...

it is sometimes difficult to recognize a jaw lesion as osteosarcoma, ossifying fibroma or ‎fibrous dysplasia in routine hematoxylin and ‎eosin staining and a more accurate technique is needed to differentiate these ‎lesions. ‎many studies have shown the potential usefulness of silver-stained nucleolar organizer region (agnor) parameters for the diagnosis of various neoplasms. this study was car...

Anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID) is characterized according to its various manifestations, which include ectodermal dysplasia, vascular anomalies, osteopetrosis, and diverse immunological abnormalities such as susceptibility to pathogens, impaired antibody responses to polysaccharides, hypogammaglobulinemia, hyper-IgM syndrome, impaired natural killer cell cytotoxi...

Many endoscopic imaging modalities have been developed and introduced into clinical practice to enhance the diagnostic capabilities of upper endoscopy. In the past, detection of dysplasia and carcinoma of esophagus had been dependent on biopsies taken during standard white-light endoscopy (WLE). Recently high-resolution (HR) endoscopy enables us to visualize esophageal mucosa but resolution for...

Single umbilical artery (SUA) is the most common abnormality of the umbilical cord. It is associated with an increased incidence of atresia of hollow organs, renal abnormalities, limb reduction defects and spontaneous abortions. The aetiopathogenesis, although unknown, is attributed to vascular disruption. In this study, 15 foetal autopsies with SUA, seen over a one-year period have been review...

Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu-Disease (OWRD) is a rare autosomal dominant disorder that affects blood vessels and consequently multiple systems resulting in a tendency to bleed. Also known as vascular dysplasia, the condition is more or less diagnosed clinically and has a variable prognosis depending on prompt recognition and severity. However, there is no cur...

Osler-Weber-Rendu disease (OWRD) or Hereditary Hemorrhagic Telangiectasia (HHT) is a rare autosomal dominant disorder that causes muco-cutanesous and visceral vascular dysplasia and results in increased tendency for bleeding [1-4]. Patients with HHT may present with variety of symptoms and management differs accordingly. Epistaxis is the most common symptom of HHT and mucocutaneous telangiectas...

Background Bronchopulmonary Dysplasia (BPD) is a multifactorial disease with a significant genetic component. Twin studies indicate that heritability of BPD is estimated at 53 to 79% [1]. Association studies have identifiedseveral potential candidate genes encoding components of innate immune and antioxidant defenses, mechanisms of vascular and lung remodeling, matrix remodeling proteins, surfa...
