Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterised by epistaxis, mucocutaneous telangiectasia with systemic manifestations due to visceral telangiectasia and arterio-venous malformations (AVMs). We describe unusual complications of HHT in a 68-year-old male who developed high-output cardiac failure with pulmonary hypertension in combination with hepatic...
Patients with germline mutations in SMAD4 can present symptoms of both juvenile polyposis syndrome (JPS) and hereditary hemorrhagic telangiectasia (HHT): the JP-HHT syndrome. The complete phenotypic picture of this syndrome is only just emerging. We describe the clinical characteristics of 14 patients with SMAD4-mutations. The study was a retrospective, register-based study. SMAD4 mutations car...
INTRODUCTION More than 3 decades have passed since the first heterotopic heart transplantation (HHT) was reported. Nowadays, this surgical technique is used rarely, and only in patients who do not qualify for standard orthotopic heart transplantation (OHT). Current indications mainly comprise refractory pulmonary hypertension and a donor-recipient size mismatch (>20%). The objective of this stu...
BACKGROUND Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant vascular dysplasia characterised by mucocutaneous telangiectasis, epistaxis, gastrointestinal haemorrhage, and arteriovenous malformations in the lung and brain. Causative mutations for HHT have been identified in two genes, endoglin and ALK1, which encode proteins involved in serine-threonine kinase signalling in ...
Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant disorder with unknown pathophysiology that is characterised by arteriovenous lesions and recurrent haemorrhage in virtually every organ. Linkage of HHT to markers on chromosome 9q has recently been reported. In this study we report confirmation of this localisation in three unrelated families of Dutch origin. A fourth unrelat...
We study a special case of Hamming-Huffman trees, in which both data compression and error detection are tackled on the same structure. Given hypercube Q n dimension , we interested some aspects its vertex neighborhoods. For subset L vertices neighborhood is defined as union neighborhoods . The minimum problem that determining cardinality over all those sets This well-known has already been sol...
One of the main heritage tools used in scientific and engineering data spectrum analysis is the Fourier Integral Transform and its high performance digital equivalent the Fast Fourier Transform (FFT). Both carry strong a-priori assumptions about the source data, such as linearity, of being stationary, and of satisfjmg the Dirichlet conditions. A recent development at the National Aeronautics an...
BACKGROUND Hwangryunhaedok-tang (HHT) is a traditional herbal medicine that is used for the treatment of fever, inflammation, gastritis, and hypertension. In this study, we performed simultaneous determination of the five components, geniposide (1), baicalin (2), coptisine (3), palmatine (4), and berberine (5) in HHT by using a high-performance liquid chromatography-photodiode array (HPLC-PDA) ...
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominantly inherited disorder of the fibrovascular tissue. The most common symptoms are recurrent nose bleeds and multiple mucocutaneous telangiectases. Arteriovenous malformations (AVMs) are less obvious. Because there is no permanent cure available, patients often suffer from mental stress. Several studies have been performed to asse...
This is the first scientific report of hereditary hemorrhagic telangiectasia (HHT) epistaxis treatment by intranasal spraying of the vascular endothelial growth factor (VEGF) inhibitor bevacizumab (Avastin). Epistaxis in patients with HHT is a morbid, mortal condition that is difficult and unpleasant to manage. Nasal telangiectasia growth is modulated by VEGF, which is elevated in HHT patients....
