2009 Lecture 1
A Course Introduction
Anatomical image of late pregnancy by Wilhelm Braune (1831-1892): Topographisch-anatomischer Atlas : nach Durchschnitten an gefrornen Cadavern, Leipzig: Verlag von Veit & Comp., 1867-1872. (Topographic-anatomical Atlas) Wilhelm Braune (1831-1892)
This first lecture will introduce the course and the subject of Embryology.
Firstly, an introduction to the course, its content and assessment and an opportunity to ask questions.
Secondly, some historic background to the subject and related current Australian trends.

Australian Statistics
The data below are highlights from the AIHW National Perinatal Statistics Unit recent annual publication: "Australia's mothers and babies 2005"
Mothers
- 29.8 years was the mean maternal age, continuing an upward trend. (More? Australian Statistics | Australian Maternal Statistics)
- 9,867 were of Aboriginal or Torres Strait Islander origin, making up 3.7% of all mothers.
- 17.4% reported smoking at all during pregnancy. (More? Smoking)
- 58.5% had a spontaneous vaginal birth (0.4% vaginal breech birth, 3.5% forceps and 7.2% vacuum extractions). (More? Birth Overview)
- 30.3% gave birth by caesarean section (19.5% in 1996) (More? Caesarean Delivery)
- 83.2% had previously had a caesarean section
- 1.7% had a multiple pregnancy (More? Twinning)
- 3.0 days median length of stay in hospital (caesarean section 5.0 days)
Babies
- 8.1% were preterm (less than 37 weeks gestation) (More? [../Child/birthpremature.htm Premature Birth] | [../Child/birthweight.htm Low Birth Weight])
- 6.4% of liveborn babies were of low birthweight (less than 2,500 grams) (More? [../Child/birthweight.htm Low Birth Weight] | [../Defect/page10.htm Fetal Origins Hypothesis])
- 105.5 male / 100 female live births
- 15.5% of liveborn babies admitted to a special care nursery or neonatal intensive care unit.
- 6,044 were admitted to level III neonatal intensive care units in Australia and met ANZNN’s high risk criteria, of which 78.0% were preterm.
- 7.3 /1,000 births fetal death rate (More? [../Child/birth7.htm Stillbirth and Perinatal Death])
- 3.2 /1,000 neonatal death rate / live births
- 10.5 /1,000 perinatal death rate / births
Australian Developmental Abnormalities
Ten most frequently reported birth defects in Victoria between 2003-2004 (More? Australian Statistics - Victoria)
- Hypospadias (More? Genital Abnormalities - Hypospadia)
- Obstructive Defects of the Renal Pelvis (More? Urogenital Abnormalities)
- Ventricular Septal Defect (More? Cardiovascular Abnormalities - Ventricular Septal Defect)
- Congenital Dislocated Hip (More? Musculoskelal Abnormalities - Congenital Dislocation of the Hip (CDH))
- Trisomy 21 or Down syndrome - (More? Abnormal Development - Trisomy 21)
- Hydrocephalus (More? Neural Abnormalities - Hydrocephalus)
- Cleft Palate (More? Head Abnormalities)
- Trisomy 18 or Edward Syndrome - multiple abnormalities of the heart, diaphragm, lungs, kidneys, ureters and palate 86% discontinued (More? Abnormal Development - Trisomy 18)
- Renal Agenesis/Dysgenesis - reduction in neonatal death and stillbirth since 1993 may be due to the more severe cases being identified in utero and being represented amongst the increased proportion of terminations (approximately 31%). (More? Kidney Abnormalities - Renal Agenesis)
- Cleft Lip and Palate - occur with another defect in 33.7% of cases. (More? Head Abnormalities)
