Screening for hearing impairment and deafness is not systematic in all Quebec hospitals. In certain situations, additional screening tests may be useful. Talk to your doctor if you have any concerns. The Canadian Task Force on Preventative Health Care sometimes recommends a blood test for iron deficiency anemia, especially if the baby weighed less than 2.

Diseases Screened The diseases detected, that is, 11 diseases by blood screening and 7 diseases by urine screening, may take different forms, but screening is done only for the most severe forms.
Cystic fibrosis Congenital hypothyroidism Hemoglobin diseases Metabolic diseases If left untreated, the diseases detected prevent the body from functioning normally. Cystic fibrosis Cystic fibrosis is a genetic disease that causes secretions to become thick and sticky, interfering with the proper function of the lungs and pancreas. Genetic Counselling: Though cancer is a disease that affects many families, the vast majority of common cancers such as breast, colon, and prostate cancer are not due to an inherited predisposition.
A combination of random biological events and certain environmental exposures are thought to contribute to the development of most cancers as we get older. Some characteristics of hereditary cancers include:. Our multidisciplinary team of cancer genetics specialists provides personalized cancer risk assessments based on medical and family history, and when indicated, help individuals navigate through the process of genetic testing.
Through supportive counseling and education about hereditary cancers, we help empower individuals to use genetic information to make informed decisions about cancer screening and primary prevention.
A notable feature of the Cancer Genetics Service is the timely integration of new knowledge and technologies to better serve our patient population. In serving our patients in the clinic, we strive to provide risk assessment and management recommendations based on the most up-to-date medical literature, and where possible, offer participation in research studies related to hereditary cancer.
Any person who has at least one grandparent of Ashkenazi Jewish background can be screened in our department. Although these conditions have been reported in individuals of various ethnic backgrounds, these diseases occur more frequently in people of Ashkenazi Jewish ancestry. Our clinic provides education and support to individuals with Huntington Disease, to their families and caregivers, as well as to health professionals involved in their care.
Our services include genetic consultation to those seeking information about Huntington Disease and those wishing to discuss family planning options.
We also provide predictive testing for individuals who wish to know their genetic status. We follow a specific protocol during which the individual can withdraw from the testing process at any time.
This conclusion is best supported by the results of a large controlled trial from Wessex, England [23] , and multiple subsequent cohort studies. Based on the USPSTF statement [8] , the update [2] and multiple subsequent studies, it is clear that newborn screening significantly lowers the age of diagnosis of moderate to severe hearing loss in children, with the greatest reductions occurring in children with moderate hearing loss [8] [23].
For example, in the Champagne-Ardenne region of France [24] , the median age at diagnosis of hearing impairment decreased from 17 months to 10 weeks with UNHS implementation.
The actual diagnosis of hearing loss in infants is both precise and reliable. Studies of the effectiveness of screening have examined the differences in outcomes of children who received newborn screening earlier intervention versus normally hearing children and versus unscreened hearing-impaired children later intervention; usually after 12 to 24 months of age. The impact of long-term language outcomes was ranked as uncertain in the review, and a call for further study was made.
A Cochrane review [26] , originally published in and now withdrawn due to lack of revision, cited a similar conclusion. In the most recent USPSTF review [2] , the authors concluded that there was adequate evidence demonstrating that children with an earlier diagnosis had improved expressive and receptive language scores.
Updated evidence from multiple studies [2] [27] [28] [29] now indicate that infants who are diagnosed and receive intervention before six months of age score 20 to 40 percentile points higher on school-related measures language, social adjustment and behaviour compared with hearing-impaired children who receive intervention later on [7].
Management of hearing loss is dependent on the etiology. Medical and surgical interventions focused on establishing functional access to sound have improved significantly as a result of technological advances during the past two decades.
Depending on the etiology and severity of hearing loss, this may involve hearing aids, cochlear implants or bone-anchored hearing aids. Surgical options exist for many conductive disorders including ear malformations, ossicular chain abnormalities, tumours and cholesteatomas.
Hearing aids, which offer sound amplification, are now widely available using advanced digital technology, and may be worn by very young infants. Environmental sound amplification devices, including FM and wireless devices, are also available for individuals of all ages.
Cochlear implants, used in children for the past 20 years, are electronic devices surgically placed in the cochlea to provide stimulation to the auditory nerve. A systematic study [30] showed clear effectiveness in hearing and language development. Cochlear implants, along with oral language habilitation, have transformed the hearing and language potentials of severely and profoundly deaf individuals, enabling highly functional language development.
Current recommendations for eligible children are bilateral implantation between eight and 12 months of age, coupled with auditory oral therapy [30]. This may take many forms including oral and gestural communication, or a combination of both. Families require clear, objective information on the interventional options and expected outcomes. Data from the Ontario newborn hearing screening program indicate that between and , Specialized auditory-verbal therapists, teachers of the deaf and speech therapists, who are trained to work with infants and young children and their families, are instrumental in the auditory habilitation process.
Therefore, child and family support is a key element of early intervention. For older children, liaisons with school services are important. In the position statement [7] , the JCIH summarized intervention strategies and provided recommendations. This question was systematically evaluated by Nelson et al [2] in Data were extracted from two fair-quality cohort studies and multiple survey studies.
In summary, it appears that screening is well accepted by the vast majority of parents, with rates of refusal estimated to be 0.
