Caucasian male babies with blood type B or O are more likely than other types to be affected. [22] Infants exposed to erythromycin are at increased risk for developing hypertrophic pyloric stenosis, especially when the drug is taken around two weeks of life [24] and possibly in late pregnancy and through breastmilk in the first two weeks of ...

It is approximately 1.5 centimetres (5 ⁄ 8 inch) in diameter in newborns after 35 weeks of gestational age, [7] and 2.5–3 cm (1– 1 + 1 ⁄ 8 in) in diameter in adults. On abdominal X-rays , the small intestine is considered to be abnormally dilated when the diameter exceeds 3 cm. [ 8 ] [ 9 ] On CT scans , a diameter of over 2.5 cm is ...
A thoracic aorta diameter greater than 3.5 cm is generally considered dilated, whereas a diameter greater than 4.5 cm is generally considered to be a thoracic aortic aneurysm. [4] Still, the average diameter in the population varies by for example age and sex.
The American Congress of Obstetricians and Gynecologists (ACOG) guidelines recommend a full evaluation of the maternal-fetal status, the status of the cervix, and at least a 39 completed weeks (full term) of gestation for optimal health of the newborn when considering elective induction of labour.

Abdominal aortic aneurysms are commonly divided according to their size and symptomatology. An aneurysm is usually defined as an outer aortic diameter over 3 cm (normal diameter of the aorta is around 2 cm), [43] or more than 50% of normal diameter. [44] If the outer diameter exceeds 5.5 cm, the aneurysm is considered to be large. [42]
Dilation is described using centimetres; closed, 1cm, 2cm, 3cm, etc until fully dilated at 10 cm. Fetal station −3 −2 −1, 0 +1, +2 Fetal station describes the position of the fetus's head in relation to the distance from the ischial spines, which are approximately 3-4 centimetres inside the vagina and are not usually felt.
