Cervical screening: your results explained

From January 2011, the Northern Ireland cervical screening programme no longer invited women aged under 25 to attend for screening. In addition, the screening interval for women aged 25-49 was reduced to every three years. This leaflet is one of a series of new information materials that was developed to reflect the policy changes and to give information to increase the uptake of information and interventions offered to protect and maintain the health of women in the target group. It explains the results of the cervical screening test.

In addition, the screening interval for women aged 25-49 was reduced to every three years. Thisbooklet describes the rationale for the change in policy so that primary care staff and smear takers can provide appropriate and accurate advice to patients.

Eye screening for diabetics - prevents blindness

Diabetes is a common condition affecting around 69,000 people in Northern Ireland. One of the possible complications of diabetes is a condition called diabetic retinopathy, which can cause sight loss and blindness. Retinopathy causes damage to the tiny blood vessels (capillaries) that nourish the retina, the tissues in the back of the eye that deal with light. This can seriously affect vision.Research shows that if retinopathy is identified early, for example through retinal screening, and treated appropriately, blindness can be prevented in the majority of people with diabetes, both type 1 and type 2.Screening programmeIn Northern Ireland, a diabetic retinopathy screening programme (DRSP), run by the Public Health Agency, has been put in place to screen all eligible people with diabetes aged 12 years and over. Dr Bernadette Cullen, Consultant in Public Health Medicine, PHA, said: "Screening detects problems early and allows appropriate treatment to be offered. It is vital that everyone with diabetes attends diabetic retinopathy screening when it is offered. Early detection of potential problems offers a very real opportunity to intervene and, with appropriate treatment, can prevent blindness in the majority of those at risk."The screening testThe screening test involves photographs being taken of the back of each eye, using a special camera. The test is painless and takes about 15 minutes. If the person is over 50 years of age, they will need to have drops put in their eyes about 15 minutes before the test to dilate their pupils.The photographs are sent to the regional screening centre for analysis by trained graders. Results will show whether patients require further referral for assessment or treatment by hospital eye services (HES). If this is not required, screening will be offered again the following year.GPs are informed of all results and if the patient is under the care of a diabetologist, they too will be informed. Patients are informed of results by their GP and if they need an urgent referral, protocols are in place to ensure this happens.Many people with diabetes attend their optometrist (optician) on a regular basis to have a sight test for glasses. It is important they continue to do this - this test is free to people with diabetes. It is also vital that people with diabetes attend for diabetic retinopathy screening when invited, regardless of how or where their diabetes is treated, or whether they visit a hospital consultant/GP for their diabetic care.Patients are invited to screening via their GP practice. An information leaflet to help patients make an informed decision to attend for screening is also sent. This can be accessed via the PHA website: www.publichealth.hscni.net.

Viremic blood donor found by a rapid screening method in a season of high human parvovirus B19 activity in Niterói, Rio de Janeiro, Brazil

Erythrovirus B19 infection is usually benign but may have serious consequences in patients with hemolytic anemia (transient aplastic crisis), immunodeficiency (in whom persistent infection can lead to chronic bone marrow failure with anemia), or who are in the first or second trimester of gestation (spontaneous abortion, hydrops fetalis, and fetal death). Being non-enveloped, B19 resists most inactivation methods and can be transmitted by transfusion. B19 is difficult to cultivate and native virus is usually obtained from viremic blood. As specific antibodies may be absent, and there is no reliable immunological method for antigen detection, hybridization or polymerase chain reaction are needed for detecting viremia. A rapid method, gel hemagglutination (Diamed ID-Parvovirus B19 Antigen Test), can disclose highly viremic donations, whose elimination lessens the viral burden in pooled blood products and may even render them non-infectious. In order to obtain native antigen and to determine the frequency of viremic donors, we applied this test to blood donors in a period of high viral activity in our community. Positive or indeterminate results were re-tested by dot-blot hybridization. We tested 472 donors in 1998 and 831 ones in 1999. One viremic donor was found in 1999. We suggest that in periods of high community viral activity the gel hemagglutination test may be useful in avoiding highly viremic blood being added to plasma pools or directly transfused to patients under risk.

AAA screening programme flyer

This flyer has been produced to help maximise awareness of the abdominal aortic aneurysm (AAA) screening programme in Northern Ireland. It provides important information on AAAs, the danger they pose to the health of men aged 65 and over, and the screening process. The flyers will be distributed to eligible men through the following channels, among others: public events, eg talks with men's groups, Farm Families Health Checks programme;health information stands in shopping centres, supermarkets etc;GP practices;pharmacies.

Mutation screening of SEMA3A and SEMA7A in patients with congenital hypogonadotropic hypogonadism.

Background:Congenital hypogonadotropic hypogonadism (HH), a rare disorder characterized by absent, partial, or delayed puberty, can be caused by the lack or deficient number of hypothalamic gonadotropin-releasing hormone (GnRH) neurons. SEMA3A was recently implicated in the etiology of the disorder, and Sema7A-deficient mice have a reduced number of GnRH neurons in their brains.Methods:SEMA3A and SEMA7A were screened by Sanger sequencing in altogether 50 Finnish HH patients (34 with Kallmann syndrome (KS; HH with hyposmia/anosmia) and 16 with normosmic HH (nHH)). In 20 patients, mutation(s) had already been found in genes known to be implicated in congenital HH.Results:Three heterozygous variants (c.458A>G (p.Asn153Ser), c.1253A>G (p.Asn418Ser), and c.1303G>A (p.Val435Ile)) were found in SEMA3A in three KS patients, two of which also had a mutation in FGFR1. Two rare heterozygous variants (c.442C>T (p.Arg148Trp) and c.1421G>A (p.Arg474Gln)) in SEMA7A were found in one male nHH patient with a previously identified KISS1R nonsense variant and one male KS patient with a previously identified mutation in KAL1, respectively.Conclusion:Our results suggest that heterozygous missense variants in SEMA3A and SEMA7A may modify the phenotype of KS but most likely are not alone sufficient to cause the disorder.

Dépistage organisé du cancer colorectal: défis et enjeux pour un essai pilote en Suisse. [Organized screening for colorectal cancer: challenges and issues for a Swiss pilot study].

Colorectal cancer is among the three most common and lethal neoplasms in Switzerland (about 4,000 new cases and 1,600 deaths per year, respectively). Several screening modalities are available. The effectiveness of colorectal cancer screening on mortality is established. The implementation of a successful screening intervention shall follow specified phases and conditions, and abide with global principles: pooling and coordinating efforts from all partners, setting goals and priorities, and identifying action plans. A feasibility (pilot) study is needed to verify requirements for quality, effectiveness, efficiency and innocuousness. Endeavours towards implementing a pilot programme for colorectal cancer screening in the Vaud canton (Switzerland) are presented and discussed.

The Impact of CAROtid plaque Screening on Smoking (CAROSS) cessation and control of other cardiovascular risk factors: rationale and design of a randomized controlled trial

BACKGROUND: Screening tests for subclinical cardiovascular disease, such as markers of atherosclerosis, are increasingly used in clinical prevention to identify individuals at high cardiovascular risk. Being aware of these test results might also enhance patient motivation to change unhealthy behaviors but the effectiveness of such a screening strategy has been poorly studied. METHODS: The CAROtid plaque Screening trial on Smoking cessation (CAROSS) is a randomized controlled trial in 530 regular smokers aged 40-70 years to test the hypothesis that carotid plaque screening will influence smokers' behavior with an increased rate of smoking cessation (primary outcome) and an improved control of other cardiovascular risk factors (secondary outcomes) after 1-year follow-up. All smokers will receive a brief advice for smoking cessation,and will subsequently be randomly assigned to either the intervention group (with plaques screening) or the control group (without plaque screening). Carotid ultrasound will be conducted with a standard protocol. Smokers with at least one carotid plaque will receive pictures of their own plaques with a structured explanation on the general significance of plaques. To ensure equal contact conditions, smokers not undergoing ultrasound and those without plaque will receive a relevant explanation on the risks associated with tobacco smoking. Study outcomes will be compared between smokers randomized to plaque screening and smokers not submitted to plaque screening. SUMMARY: This will be the first trial to assess the impact of carotid plaque screening on 1-year smoking cessation rates and levels of control of other cardiovascular risk factors.

Screening for memory disorders, dementia and Alzheimer's disease

Dementia and its most common cause, Alzheimer’s disease, affect memory and occur predominantly in the elderly. Dementia has become increasingly prevalent in the world as health has improved and life expectancy has increased. However, the fields of clinical care have not responded adequately to develop diagnostic tools and treatments for this rapidly increasing group of conditions. While scientists search for cures for the numerous causes of dementia, improvement of diagnostic measures are needed now and should begin with screening elderly populations for memory difficulties and other cognitive problems. This review examines the history of cognitive screening tests, the numerous excellent tests that are currently available and ready for use, and directions and methods that will lead to progressively better evaluations.

Evaluation of five screening tests licensed in Argentina for detection of hepatitis C virus antibodies

This study was conducted to compare among the most recent generation of five screening tests licensed in Argentina, in order to evaluate which of the tests has the best sensitivity for detection of antibodies against hepatitis C virus (HCV). The tests analyzed were: Detect-HCV™ (3.0) Biochem ImmunoSystems, Canada; Hepatitis C EIA Wiener Lab., Argentina; Equipar HCV Ab, Italy; Murex HCV 4.0, UK and Serodia-HCV particles agglutination test, Japan. The results obtained showed high discrepancy between the different kits used and show that some of the tests assessed have a low sensitivity for anti-HCV detection in both chronic infections and early seroconversion, and indicate that among the commercially available kits in Argentina, Murex HCV 4.0 (UK) and Serodia-HCV particles agglutination test (Japan) have the best sensitivity for HCV screening. Although the sensitivity of the assays is the first parameter to be considered for blood screening, more studies should be carried out to assess the specificity of such assays.
