“…Two of the fetuses failed to exhibit independent motion or cardiac activity, and the third had a heart rate of 218 bpm, indicating fetal stress. 12 Fetal development was advanced, with visibility of the cerebral choroid plexi, and individual heart chambers consistent with at least 50 days’ gestation (Figure 1). Morphology of fetal organs was well defined and similar in all fetuses, indicating that the demise of two fetuses had occurred within the preceding 12 h. 12 The zonary placenta were varied in appearance, and at least one was subjectively thickened, with an irregular inner margin.…”

Case summary A 7-year-old female entire Birman presented with acute-onset haemorrhagic vulvar discharge. Moderate, normocytic, normochromic, non-/pre-regenerative anaemia, along with a moderate mature neutrophilia, were seen on haematology. Saline test for agglutination was positive. No haemotropic mycoplasmas were identified. Serum biochemistry revealed severe hyperbilirubinaemia. Retroviral testing was negative. Serology for toxoplasmosis revealed a titre of 1:512. Abdominal ultrasound identified a large uterus, containing at least three advanced-stage fetuses, two of which failed to exhibit independent motion or cardiac activity. Ovariohysterectomy was performed. Histology demonstrated mild, multifocal suppurative placentitis, with Gram staining revealing no evidence of bacteria. Complete resolution of the anaemia was seen within 1.5 months of ovariohysterectomy. Relevance and novel information Immune-mediated haemolytic anaemia (IMHA) in association with pregnancy has not been previously reported in cats. This case represents a potential novel cause for IMHA in cats, which resolved following ovariohysterectomy.

“…The ultrasonography is a better method than palpation and radiography because allows to do an early diagnosis of pregnancy and record embryo or foetus viability, as early as 10 days after mating (Davidson & Baker, ; Zambelli et al, ; Zambelli & Prati, ). Ultrasonography supports estimation of gestational age, embryonic or foetal maturation and the date of delivery by measuring various extra‐foetal and foetal structures (Beccaglia et al, ; Lopate, ; Topie, Bencharif, Briand, & Tainturier, ; Zambelli et al, ).…”

Contents The objective of study was to derive specific growth curves of ICC and BP for Maine Coon. Twenty‐three pregnant queens aged 1–6 years, with body weight of 4.5–7.6 kg, were included in the study. In each queen, serial ultrasonographic examinations of pregnancy were performed through the abdomen with the MyLab Gold Vet scanner with a 6.6–7.5 MHz microconvex probe (Turin, Italy). ICC or BP was measured, depending on the stage of pregnancy. Each examination was regarded as a separate observation. In 18 queens, ICC was measured 33 times, and in 21 queens, BP was measured 60 times. The linear regressions of specific models of ICC and BP in Maine Coon pregnancies and specific formulas for predicting the parturition date in this breed were derived. The ICC formula was: days before parturition (DBP) = −0.79 * mm + 57.9, and the BP formula was: DBP = −1.86 * mm + 49.3. The proposed fetometric formulas of ICC and BP for Maine Coons after application in clinical patients can improve obstetric management in this breed.

Prenatal diagnosis of foetal hydrocephalus and suspected X-linked recessive inheritance of cleft lip in a Chihuahua

A 3.5-year-old, 2.9 kg, multiparous Chihuahua presented with abdominal distension; pregnancy was diagnosed. On Day 7 before parturition, prenatal sonograms showed anechoic bilateral dilated cerebral lateral ventricles, suggesting fluid-filled regions (ventriculomegaly) in one foetus. A Caesarean section was performed and the male newborn had an abnormally enlarged dome-shaped head and a cleft lip, and died 6 days after birth. According to the family pedigree, the X-linked recessive inheritance of an orofacial cleft from the unaffected mother was suggested. This report clearly demonstrates that canine foetal ventriculomegaly (hydrocephalus) can be diagnosed in utero. For dog breeds predisposed to congenital ventriculomegaly, early detection is important for the prediction of perinatal survival and adequate supportive care can be applied at delivery.
