Normal Composition

In order to define the normal composition of canine amniotic fluid and to detect differences between surviving and non-surviving newborn puppies, the present study determined the uric acid, glucose, lactate and creatinine concentrations and the lactate to creatinine ratio in amniotic fluids collected during elective Caesarean section from small-sized purebred bitches. The possible relationship between newborn survival and the studied parameters, as well as the effects of maternal parity, fetal gender and Apgar score were assessed. The study enrolled 27 small-sized purebred bitches submitted to elective Caesarean section at term. After opening the fetal membranes, amniotic fluid samples were collected aseptically from the amniotic sac of each fetus. The data obtained from 74 amniotic fluid samples collected from 27 bitches showed that amniotic glucose concentration was lower (P < 0.05) in non-surviving than in surviving puppies. Within the normal, surviving puppies, amniotic glucose concentration was higher (P < 0.05) in male than in female newborns, and the lactate/creatinine ratio was significantly higher in multiparous than in primiparous bitches (P < 0.05). These preliminary results demonstrate the relevance of amniotic glucose, but not of uric acid, lactate, creatinine and the lactate to creatinine ratio for detecting puppies at risk of death immediately after birth.

Abstract Parathyroid hormone-related protein (PTHrP), the hypercalcaemia of malignacy factor, is expressed in the tissues of the human uteroplacental unit, including the placenta, amnion and chorion. We have used three region-specific immunoassays to quantitate and compare the distribution of PTHrP in tissues obtained at term following spontaneous labour and vaginal delivery or elective Caesarean section. In non-labouring women highest PTHrP(1–86) and (37–67) immunoreactivity was found in amnion covering the placenta, rather than the decidua parietalis of the uterus (reflected amnion) (median 1020 vs 451 fmol/g; 2181 vs 1444 fmol/g respectively). In labouring women, the PTHrP(1–86) concentration in reflected amnion was inversely correlated with the interval between rupture of the membranes and delivery. Tissue PTHrP(1–86) concentrations were lower in placenta than in chorion and amnion (medians 12, 109 and 664 fmol/g respectively) and, in all tissues, PTHrP(1–34) and (37–67) concentrations were significantly higher than that of PTHrP(1–86). Bioactive PTHrP(1–34) was detected in placenta, chorion and amnion using the ROS cell bioassay. The PTHrP(1–86) concentration (mean ± s.e.m.=41·4 ± 4·5 pmol/l) was high in amniotic fluid at term, although in maternal and cord plasma levels were only modestly increased. The molecular forms of PTHrP present in tissues and amniotic fluid were investigated by column chromatography which confirmed its molecular heterogeneity and suggested that processing is tissue-specific and occurs at both amino- and carboxy-terminals of the peptide.

Spontaneous Labour

A 34-year-old primiparous woman presented in spontaneous labour and had an unassisted vaginal birth of a 3.5 kg infant. Postnatally, the patient experienced lower limb weakness and was unable to mobilise unassisted. A diagnosis of postpartum femoral neuropathy was made. Full recovery of normal motor function was not achieved until 5 months postpartum. She returned in her next pregnancy, seeking advice on how to avoid this complication from reoccurring. It was decided that an elective caesarean section was an appropriate mode of delivery, which she underwent at 39 weeks without complication and without recurrence of the femoral neuropathy.
