Objective: To review the use of transvaginal ultrasound for the diagnosis of placenta previa and recommend management based on accurate placental localization. Options: Transvaginal sonography (TVS) versus transabdominal sonography for the diagnosis of placenta previa; route of delivery, based on placenta edge to internal cervical os distance; in-patient versus out-patient antenatal care; cercl...

the human placenta has long been the subject of scientific interest due to the important roles which it performs during pregnancy in sustaining the fetus and maintaining fetomaternal tolerance. more recently, however, researchers have begun to investigate the possibility that the placenta’s utility may extend beyond fetal development to act as a source of cells with clinically relevant properti...

Placenta previa can be difficult to diagnose with transabdominal sonography during the third trimester of pregnancy, because of difficulties in imaging the cervix late in pregnancy. Although transperineal sonography offers an additional view of the cervix, its value in the diagnosis of placenta previa has not been studied. Accordingly, we performed transperineal sonography on 164 patients who h...

There is an expectation that animal suffering associated with pest management be minimised. The most humane methods that will achieve the control program’s aims must be used. Consideration of animal suffering should occur regardless of the status given to a particular pest species or the extent of the damage or impact created by that pest. While the ecological and economic rationales for the co...

BACKGROUND H3N8 canine influenza virus (CIV) infection might contribute to increased duration of shelter stay for dogs. Greater understanding of factors contributing to CIV within shelters could help veterinarians identify control measures for CIV. OBJECTIVES To assess community to shelter dog CIV transmission, estimate true prevalence of CIV, and determine risk factors associated with CIV in...

Attachment to pets has an important role in children's social, emotional, and cognitive development, mental health, well-being, and quality of life. This study examined associations between childhood attachment to pets and caring and friendship behaviour, compassion, and attitudes towards animals. This study also examined socio-demographic differences, particularly pet ownership and pet type. A...

Several major vascular tissues, such as the aorta-gonad-mesonephros region (AGM), yolk sac, and fetal liver have been confirmed to possess hematopoietic function. Recently, the placenta has been demonstrated as another hematopoietic organ. However, it is not conclusive whether the placenta possesses hematopoietic ability. Therefore, we undertook a series of experiments to study the hematopoieti...

Objective Concurrent placenta previa and placenta accreta increase the risk of massive obstetric hemorrhage. Despite extensive research on the management of placenta previa (including placenta accreta, increta, and percreta), the number and quality of previous studies are limited. We present a case of placenta accreta requiring an induced second-trimester abortion because of premature rupture o...
