Summary

A 3033g male infant was born to a healthy mother at 39 weeks gestation by normal vaginal delivery with Grade 1 meconium stained liquor. There was no prolonged rupture of membranes or any antenatal risk factors for sepsis. The immediate neonatal period was uneventful and the baby was discharged after two days. At 6 weeks of age the baby was admitted with an 8-hour history of inconsolable crying. He was pyrexial. Initially the possibility of intussuception was considered, however, the submandibular swelling became more obvious and tender. His airway was clear. Chest x-ray and abdominal x-ray were normal. Ultrasound of the submandibular region showed soft tissue swelling with no fluid collection. CRP was initially 0.7 but increased to 87 the next day. Blood cultures grew group B streptococcus. (GBS) He was treated for five days with appropriate intravenous antibiotics. He was discharged home and recovered fully.
