Discovery of cell free fetal DNA in 1997 has deeply changed the outlook of prenatal diagnosis approaches as most of the clinically established screening tests are not sensitive/specific enough while the current practical diagnostic tests are also invasive in their nature. The most common prenatal screening test is routinely practiced for the diagnosis of Down syndrome (DS) which includes a 10% ...
Intrathoracic splenosis is a generally asymptomatic entity incidentally diagnosed after the completion of an Rx, CT scan or MRI for another reason. The performance of scintigraphy with (99m)Tc-labelled heat-denatured erythrocytes allows the noninvasive diagnosis of this entity and avoids more aggressive diagnostic techniques such as FNAP or thoracotomy. Because this splenic tissue may be partia...
In the Prenatal Diagnosis special issue of July 2010, a good prediction was made by the author (Dennis Lo, 2010) on non-invasive methods of diagnosis of fetal anomalies. Non-invasive prenatal diagnoses are useful in the detection of fetal genetic abnormalities, aneuploidies and high-risk pregnancy. Fetal DNA analysis in maternal plasma using single molecule analysis method, no doubt, will defin...
The natural history of Chagas' disease and its manifestations when the heart is involved are detailed clinically and pathologically. Three phases are recognized: the acute phase, lasting from 1-3 months, the latent phase, which may last from 10-20 years, and the chronic phase, which has the most serious manifestations. This phase is subdivided into three clinical stages. An analysis of the vari...
