Bevacizumab dramatically improves severe hereditary hemorrhagic telangiectasia (HHT) associated bleeding
(Elsevier) Patients with hereditary hemorrhagic telangiectasia (HHT) with severe bleeding, who were treated with intravenous bevacizumab, reported a marked reduction in nose bleeds and gastrointestinal bleeding and were able to stop or considerably reduce blood transfusions, resulting in significantly improved quality of life. A new study published in Mayo Clinic Proceedings provides good quality evidence for the excellent safety profile and efficacy of intravenous bevacizumab in the management of these patients.

Should I Worry About This Telangiectasia?
Discussion Vascular stains are common problems that parents seek guidance about as they are often particularly worried that there may be an underlying problem or that it may be a long-term cosmetic problem. Fortunately many resolve or become less prominent or have treatment available. The term vascular stains includes all vascular malformations but commonly refers more directly to capillary malformations which are quite common. Some common vascular stains include: Nevus simplex Names: Angel’s kiss (glabella or forehead), salmon patch, stork bite (nape of neck), nevus roseus, fading macular stain Epidemiology: Very ...

Inactivating mutations in Drosha mediate vascular abnormalities similar to hereditary hemorrhagic telangiectasia
We report that mice lacking Drosha in the vascular endothelium developed a vascular phenotype resembling HHT that included dilated and disorganized vasculature, arteriovenous fistulae, and hemorrhages. Exome sequencing of HHT patients who lacked known pathogenic mutations revealed an overrepresentation of rare nonsynonymous variants of DROSHA. Two of these DROSHA variants (P100L and R279L) did not interact with Smads and were partially catalytically active. In zebrafish, expression of these mutants or morpholino-directed knockdown of Drosha resulted in angiogenesis defects and abnormal vascular permeability. Together, our ...

Iron tablets may damage DNA
Conclusion This study showed that iron can induce a DNA damage response at a genetic level in isolated human endothelial cells in the laboratory. The study was early stage and packed with limitations and questions needing answers through further research. So it is not close to the stage where doctors need to change their approach to prescribing iron supplements. Similarly, this study is no reason to stop taking iron medication as prescribed, and stopping could be harmful. Keep calm and carry on. The fact iron causes a DNA repair response does not necessarily mean it causes damage or disease. It may stress the cell out, bu...
