Tritrichomonas foetus, a venereal pathogen of cattle, was recently identified as an inhabitant of the large intestine in young domestic cats with chronic diarrhea. Recognition of the infection in cats has been mired by unfamiliarity with T. foetus in cats as well as misdiagnosis of the organisms as Pentatrichomonas hominis or Giardia sp. when visualized by light microscopy. The diagnosis of T. ...

Foetus in foetu, a descriptive term attributed to Meckel (circa 1800), should be applied only to those rare cases where a parasitic twin is found included within the abdomen of its partner. Lord (1954; 1956) reported two definite cases and reviewed other possible cases. In contrast, the variety of teratoma which occurs in the retroperitoneal space is much less defined. Since the description of ...

drug retention at a time when her dietary intake was below the level of 400 ,zg folic acid-the level shown by Kahn to be necessary to counteract co-trimoxazole antagonism of folic acid. In addition to these factors, however, it may be expected that her folic acid consumption was much higher than normal as she had evidence of a significant haemolytic anaemia. It is well known that a haemolytic a...

The first Rh-sensitized pregnancies of Rhnegative women do not end in death of the embryo or foetus more often than do the pregnancies of other women. In subsequent sensitized pregnancies the death rate of Rh-positive foetuses is markedly increased. These latter foetal deaths always occur in the second half, and most of them in the last third, of pregnancy: Rh-sensitization is not a cause of de...

Regulation of foetal development in sheep depends on interactions between the intrinsic capacity of the foetus for growth and the maternal environment. Lambs born in multi-foetus litters have relatively small placentae with fewer cotelydons, and lower birth weights. Litter-size-dependent intrauterine growth restriction (IUGR) is evident at mid gestation when metabolic needs of the conceptus are...

The case here presented casts doubt on the absolute reliability of Spalding's sign, and indicates that loss of tissue fluids in the foetus may lead to overlapping of bones while the foetus may be, in fact, still alive, though perhaps in a weakened condition. It may further be noted here that, in a dead foetus, the general loss of tone may lead to a degree of collapse of the chest wall, which ma...

Thyroid hormones are essential for normal brain development, growth and energy metabolism [1]. During early pregnancy, the foetus is entirely dependent on maternal thyroid hormones and in the second and third trimesters, maternal thyroid hormones continue to provide sufficient thyroid hormones until birth [2,3]. Maternal thyroid disease is common during pregnancy with hyperthyroidism during pre...

Amnioscopy is available as an out-patient procedure, whenever hazards threaten the life of the foetus during late pregnancy. An endoscope-the amnioscope-is passed into the cervical canal so that the amniotic fluid can be inspected through the intact forewaters. Amniotic fluid which is clear, or milky from emulsification of vernix, indicates that conditions within the uterus are normal. Green or...

Breast cancer is one of the most commonly diagnosed cancers in pregnant women. Diagnosis and treatment in these women are particularly challenging as the necessary investigations and treatment modalities may potentially harm the developing foetus. Nonetheless, it appears that initial diagnostic investigations may be carried out as for non-pregnant women, but bearing in mind the risks of exposin...
