Chapter 2 Neonatal disorders

Conditions of umbilicus (navel)

Navel ill (omphalophlebitis)

Clinical features

lacking skin or any other protective layer, the moist, fleshy navel cord is particularly prone to infection until it dries up, normally within 1 week of birth. In the first calf (2.3) (shown at 3 days old) the enlarged and still moist navel cord is seen entering an inflamed and swollen umbilical ring. Navel ill is uncommon at this age.

The more typical case is pyrexic, with a swollen, painful navel exuding a foul-smelling creamy-white pus (2.4). Culture usually reveals a mixed bacterial flora including Escherichia coli, Proteus, Staphylococcus, and Arcanobacterium pyogenes. This case persisted for several weeks.

Alopecia on the medial aspects of the thighs (2.5) is due to a combination of urine scald and excessive cleansing of the navel by the owner. Some cases show no gross discharge, but the tip of the swollen navel will be moist and malodorous.

In other cases an intra-abdominal abscess may develop in the omphalic (umbilical) vein. In 2.6, A shows the intra-abdominal abscess in the grossly distended umbilical vein, adjacent to the navel, B. Spontaneous rupture of the abscess can lead to death from peritonitis, as in this calf. Occasional cases involve the urachus to produce a cystitis which can lead to stunted growth, sickness, and death several months after birth.

Septicemia can result in localization of infection in the joints (2.48, 2.49), meninges, endocardium, or end-arteries of limbs.
