Newborn screening increases

Issue: BCMJ, vol. 51, No. 10, December 2009, Page 452 News

Newborns across the province are now being screened for an additional 12 (formerly 6) treatable disorders through the BC Newborn Screening Program.

The 18 disorders screened through the program, a service of the Pro­vincial Health Services Authority (PHSA), include metabolic, endo­crine, blood disorders, and cystic fibrosis. In October 2010, a 19th disorder (congenital adrenal hyperplasia) will be added.

Early identification of these disorders allows treatment that may prevent severe mental handicap, growth problems, health problems, and sudden infant death. Blood collection takes place at all BC and Yukon hospitals where babies are delivered. About 40000 babies are screened each year; one in 1000 will be affected with one of these disorders (about 40 babies per year). The amount of blood required for the additional testing has not increased.

BC is one of the first jurisdictions in Canada to implement second-tier testing (an additional test performed on the original blood sample when the first screen is positive) for selected disorders. Running two tests before reporting the results helps confirm abnormal results and reduce false-positive results. Second-tier testing for cystic fibrosis was implemented in November 2009 and in 2010 will be implemented for six other conditions.

The program encourages physicians to talk to their pregnant pa­tients about newborn screening so they are prepared for it at the baby’s birth. Physicians are also welcome to refer their patients to the program website for details about screening.

Above is the information needed to cite this article in your paper or presentation. The International Committee of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
