A report of Fetus in fetu (FIF) by Murtaza et al.1 in Oman Medical Journal 25 (2010) was an interesting presentation. One must congratulate the authors for a good presentation. There are however some areas to be highlighted for the benefit of the scientific world. The patient presented by Murtaza A at al.1 is not the oldest patient in the literature to date. Hoeffel at al.2 review shows that on...

OBJECTIVES This study was conducted to investigate the presentation and outcome of patients with Ebstein's anomaly of the tricuspid valve. BACKGROUND Ebstin's anomaly may present at any age and has a highly variable clinical course. Previous natural history studies have been based on clinical and angiographic diagnosis and have included mainly older children and adults. Echocardiography, howe...

Abstract Objectives Fetus-in-fetu is a rare congenital anomaly that occur secondary to abnormal embryogenesis in diamniotic monochorionic pregnancy. Its diagnosis can be accurately made by imaging ultrasonography, radiography, computed tomography, or magnetic resonance imaging. Differential an important issue because FIF, teratoma and cystic meconium peritonitis are very different terms of thei...

How the fetus escapes rejection by the maternal immune system remains one of the major unsolved questions in transplantation immunology. Using a system to visualize both CD4+ and CD8+ T cell responses during pregnancy in mice, we find that maternal T cells become aware of the fetal allograft exclusively through "indirect" antigen presentation, meaning that T cell engagement requires the uptake ...

The immunologic interaction between the fetus and the mother is a paradoxical communication that is regulated by fetal antigen presentation and/or by recognition of and reaction to these antigens by the maternal immune system. There have been significant advances in understanding of abnormalities in the maternal-fetal immunologic relationship in the placental bed that can lead to pregnancy diso...

Background: Immune-mediated haemolytic disease of the newborn refers to a specific category anaemia that results from transplacental passage IgG antibodies pre-sensitized mother her fetus in utero. This occurs due blood group incompatibility between and fetus. The clinical presentation covers wide spectrum spanning still births erythroblastosis fetalis as well infants born with only mild haemol...

Observations were made on 475 fetuses carried by 71 pregnant rabbits. 63 or 88.7 per cent of the 71 does were sacrificed from 28 to 31 days after the last fertile mating, and these does bore 401 or 88.2 per cent of the total of 455 fully developed fetuses. The following information was available with reference to each fetus: age, weight, weight of corresponding placenta, horn, i.e., right or le...
