Hutchison's Clinical Methods, first published over a century ago, is the classic textbook on clinical skills. It provides an outstanding source of learning and reference for undergraduate medical students and postgraduate doctors. It seeks to teach an integrated approach to clinical practice, so that new methods and investigations are grafted onto established patterns of clinical practice, rather than added on as something extra. The text is organised so that both system-related and problem-oriented chapters are included. Particular emphasis is placed on the importance of the doctor-patient relationship, the essential skills needed for clinical examination, and for planning the appropriate choice of investigations in diagnosis and management.
The conventional methods of prenatal diagnosis are being challenged by recent technologies. Chromosomal microarrays already in mainstream use for postnatal genetic diagnosis are increasingly used for prenatal diagnosis, mainly in pregnancies with sonographic anomalies but also for routine screening after any invasive procedure. Arrays have demonstrated the ability to detect submicroscopic copy number variations, providing an approximately 2.1 % increase in the detection rate of pathogenic copy number variations regardless of the referral indication, and rising to an approximately 5.3 % increase above conventional karyotyping in the presence of sonographic anomalies. More recently, novel technologies and methods of non-invasive prenatal testing are reaching clinical applications beyond fetal sex determination and rhesus blood group genotyping. Massively parallel sequencing methods have been shown to confidently detect trisomy 21 from cell-free DNA isolated from a maternal plasma sample and are rapidly entering clinical use. Targeted methods including epigenetic differences between the fetal and maternal genomes such as differential methylation are also being applied for non-invasive aneuploidy detection. It can be anticipated that very soon chromosomal microarrays will become the first-tier test for invasive prenatal diagnosis. In addition, we believe that non-invasive prenatal testing will gradually replace the need for invasive prenatal diagnosis with the associated risk of pregnancy loss.
The ethical questions posed and lessons learnt in the application of arrays to prenatal diagnosis will assist greatly as sequencing of the fetal genome by non-invasive methods moves closer to clinical applications. Additionally, the experience currently being gained in clinical diagnostic whole-genome/exome sequencing will assist in considering how these techniques can be best offered in the prenatal setting and ultimately for non-invasive prenatal diagnosis. 2b1af7f3a8
