Creating a Digital Object Identifier Link

A digital object identifier (DOI) can be used to cite and link to electronic documents. A DOI is guaranteed never to change, so you can use it to link permanently to electronic documents.

To find a document using a DOI

  1. Copy the DOI of the document you want to open.
    The correct format for citing a DOI is as follows: doi:10.1016/S0140-6736(08)61345-8
  2. Open the following DOI site in your browser:
    dx.doi.org
  3. Enter the entire DOI citation in the text box provided, and then click Go.
    The document that matches the DOI citation will display in your browser window.

The DOI scheme is administered by the International DOI Foundation. Many of the world's leading publishers have come together to build a DOI-based document linking scheme known as CrossRef.

Objectives:

To prevent transmission of inherited diseases the PGD technique selects disease free embryos prior to uterine implantation.

Background:

During the last decades a number of inherited, monogenic cardiac diseases that may have a very grave prognosis have been identified.

Methods:

Genetic testing of embryos prior to implantation in the uterus allows for in vitro selection of an embryo without a specific gene mutation.

Results. We describe two familial cases in which the need for conventional prenatal diagnosis with the the implied possibility that a abortion would have to be considered was bypassed using the PGD technique.

Conclusions:

Younger patients from families afflicted with inherited diseases will demand a multidisciplinary approach including genetic counselling. Even if low pregnancy rates and high costs associated with PGD must be held against an individual evaluation of the health related risks faced by an afflicted child, cardiologists will need to bear this option in mind when managing patients with inherited cardiac diseases.
