“…The fetus actively changes its intrauterine presentation using a whole range of movements such as kicking, twisting, and locomotion (11). The cornual-fundal location of the placenta can directly, mechanically, prevent the turning of the fetus from cephalic to breech presentation in two ways.…”

AimTo investigate the association of cornual-fundal location of the placenta and breech presentation at term delivery.MethodsThis study was conducted at the Department of Obstetrics and Gynecology, Novi Sad, in 2011. The inclusion criteria were delivery at ≥37 weeks of gestation, singleton gestation, and cornual-fundal location of the placenta determined by ultrasonography at ≥37 weeks of gestation when 3/4 or more of the placenta was in the cornual-fundal region.ResultsOut of 2750 ultrasound examinations performed, 143 showed cornual-fundal location of the placenta (frequency 5.2%). Eighty six cases had cephalic presentation (60.14%) and 57 (39.86%) had breech presentation. Of the remaining cases with non- cornual-fundal location, 2585 had cephalic presentation and 22 (0.84%) had breech presentation. The difference in the frequency of breech presentation between the cornual-fundal and non-cornual-fundal groups was significant (χ2 = 77.78, P < 0.001).ConclusionCornual-fundal location of the placenta may be an important clue in resolving the etiology of a number of cases of breech presentation at term delivery.

“…In the second part of gestation there was an up to 95-100% increase in anterior (cephalic) presentation with a consequential decrease in posterior (breech) presentation and transverse lie (Reimers et al 1973;Scanlon 1975;Scanlon 1976;Miller & Kouam 1981;Cho et al 1985). In humans and sheep, the second part of gestation is characterised by the maturation of a higher level of CNS responsible for body posture and locomotion (Berger et al 1997;Sekulić 2000). The abovementioned altricial species (dog, pig) belong to the polytocous mammalian group.…”

“…This period is characterized by frequent changes from anterior (cephalic) into posterior (breech) presentation and vice versa. This period of gestation could be called the period of accidental presentation (Sekulić 2000). In the altricial species this period lasts till the end of gestation while in the precocial and human species it is followed by a period of exclusive increase in anterior (cephalic) presentation.…”

“…Posterior (breech) presentation is followed by an abnormal delivery mechanism with an increased incidence of perinatal morbidity and mortality of neonates (Sekulić 2000). In the altricial species both anterior and posterior presentations provide the physiological delivery mechanism.…”

“…In cases of the absence of postural development, the probability of breech and cephalic presentation is equal, i.e., 50 : 50. In the altricial species, postural and locomotor development mostly takes place postnatally, so at birth they show an equal incidence of anterior and posterior presentations (Sekulić 2000).…”

The aim of this research is to determine the probability of anterior and posterior presentation during the second half of gestation and at delivery among albino mice. Each day from the 10 th to the 21 st day of gestation, foetal presentation and lie were determined in uteri of six pregnant females. The chi-square test did not show any statistically significant difference in the incidence of anterior and posterior presentation between the right and left horn. In addition, there was no significant difference between anterior and posterior presentation in relation to the site in the horn or in relation to gestation days. At delivery, there was no significant difference in the incidence of anterior and posterior presentation (29 versus 31 cases). The results show that, in the albino mouse, foetal presentation during the second half of gestation and at birth is accidental, with equal probability for anterior and posterior presentation.

A Case of Maternal and Perinatal Death in Neolithic Southern Vietnam, c. 2100–1050 BCE

Despite ostensibly elevated rates of young female mortality in the past, believed to be associated with the risks of pregnancy and child birth, surprisingly few cases of pregnant female burials are reported in the bioarchaeological literature. This paper describes and discusses the case of a young female who died and was interred with an unborn full-term breech foetus at the Neolithic site of An Son, southern Vietnam c. 2100-1050BCE. Her exceptionally poor oral health, evidence for cribra orbitalia, linear enamel hypoplasia, small stature and compromised gynaecological competence, contributes to a differential diagnosis that explores a range of additional complications that may have contributed to the death of both mother and unborn child. An examination and appreciation of this case contribute to our knowledge of the reproductive age and health of young females in Neolithic Southern Vietnam and the challenges they faced during pregnancy and childbirth.
