Brief summary
HHT is a relative rare autosomal dominant inherited disorder of the fibrovascular tissue. Diagnosis of HHT is often delayed for decades (Pierucci 2012). However, it would be desirable to achieve an early diagnosis as early screening and treatment decrease disease-associated complications and increase life expectancy (Kroon 2018). Our approach is a nationwide call and awareness campaign to dentists in Germany, as nearly all persons visit a dentist from time to time. This approach is promising to us, as most patients develop nosebleeds and multiple, typical telangiectases of the skin or mucosa. A predilection site is the oral mucosa and the face, including the lips (Shovlin 2000).
Detailed description
The German self-help group is taking down the number of inquiries from patients and physicians per months since April 2017. In June 2018 an article about HHT is planned to be published in the journal of the German dental association and the Federal Association of Fund Dentists of Germany. This journal is distributed to all dentists in Germany and is a set book for them. Total circulation in 2017 was 77,621 (http://www.aerzteverlag.de/portfolio/fachwissen-medizindental/zm-zahnaerztliche-mitteilungen/profil/ ). The article describes the case of visceral abscesses after dental screening in a patient with HHT and pulmonary arteriovenous malformations. These could probably have been prevented if the dentist had prescribed an antibiotic prophylaxis to the patient. The article includes a call to search for telangiectases. If those are seen the dentist is recommended to ask the patient if he or relatives have nosebleeds. If both apply, the dentist is asked to inform the patient about HHT and give him the address of the national German self-help group. After 3 and 6 months a reminder shall be published in the same journal.
