Chorionic villus sampling (CVS) is a test used for prenatal diagnosis [5]. Safe to perform at an earlier stage in pregnancy [6] than amniocentesis, CVS is another invasive prenatal diagnostic test that can be performed as early as ten weeks after the woman?s last menstrual cycle. While this test does carry some risks, it is generally very effective at predicting heritable diseases during or soo...

BACKGROUND Research and surveillance work addressing ectopic pregnancy often rely on diagnosis and procedure codes available from automated data sources. However, the use of these codes may result in misclassification of cases. Our aims were to evaluate the accuracy of standard ectopic pregnancy codes; and, through the use of additional automated data, to develop and validate a classification a...

If diagnostic imaging during pregnancy is performed, potential risks not only for the mother but also for the fetus have to be considered. Ultrasonography should be performed primarily because it is harmless for the fetus. Other imaging modalities like x-ray, computed tomography (CT) and magnetic resonance imaging (MRI) should be reserved for cases in which results of ultrasonography are inconc...

OBJECTIVE To report frequencies of gestational diabetes mellitus (GDM) among the 15 centers that participated in the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study using the new International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria. RESEARCH DESIGN AND METHODS All participants underwent a 75-g oral glucose tolerance test between 24 and 32 weeks' gest...

background: vaginal sonograghy and serial -hcg are the most common diagnostic methods for ectopic pregnancy but about 50% of cases are initially misdiagnosed. in tubal pregnancy the zygote lies next to the muscular layer, and this invasion causes an increase in creatine phosphokinase (cpk) in blood. objective: assessment of cpk and its isoenzyme cpk-mb as a diagnostic marker for tubal pregnanc...

Current algorithms for the diagnosis of ectopic pregnancy do not take into account the heterogeneity in patient profiles. Such heterogeneity can lead to differences in the pre-test probability of ectopic pregnancy. In patients with clinical symptoms, for example, the probability of presence of an ectopic pregnancy is higher than in symptom-free patients. Any additional tests should then be inte...

BACKGROUND There is no UK consensus for screening methodology, diagnosis and management of gestational diabetes mellitus (GDM). AIM To evaluate routine practice for GDM management across the UK. METHODS Questionnaires were sent to all members of the Association of British Clinical Diabetologists. They were asked to describe how patients were screened for GDM, the diagnostic criteria and sub...
