Aseptic sialadenitis in preterm infants associated with long-term oro-gastric tube feeding.
Sialadenitis is a rare disease in the newborn and the pathogenesis in this age group is not fully understood. We report five cases of neonatal sialadenitis in stable preterm, gavage-fed infants at 2 to 6 weeks postnatal age. The occurrence of sialadenitis was observed in temporal relation to changes in enteral feeding routines in the unit which were initiated with the objective of promoting full breast feeding at discharge. Clinical presentation consisted of a tender palpable mass over one of the salivary glands, low-grade (37.5-38.3 degrees C) fever in conjunction with clinical malaise. C-reactive protein and white blood cell count were only moderately elevated. No suppuration from salivary ducts was present. Bacterial cultures were invariably negative. Viral investigations were not carried out. Aseptic sialadenitis was suggested as the cause of the symptoms. The clinical course was benign and the local tender mass over the salivary gland vanished shortly after intravenous fluids and antibiotics were started.


CONCLUSIONS
Long-term exclusive oro-gastric feeding may result in reduced reflex salivary gland stimulation, saliva production and hence ductal clearance of mucoid saliva, leading to functional ductal obstruction and local inflammation.
