Urinary tract infection due to Staphylococcus lugdunensis in a healthy child.

Staphylococcus lugdunensis is being increasingly reported as a pathogen with an outcome resembling that of Staphylococcus aureus rather than coagulase-negative staphylococci. The authors describe a case of a child with left grade II vesicoureteral reflux and pyelonephritis caused by Staphylococcus lugdunensis. The child was successfully treated with cefotaxime.

Late-onset neonatal sepsis due to Hafnia alvei.

Hafnia alvei infections are uncommon, and usually occur in patients with underlying illnesses, mainly adults. The authors describe a rare case of late-onset community-acquired neonatal sepsis in an infant without any underlying disease. The infant was successfully treated with cefotaxime.

Early-onset neonatal sepsis caused by vertical transmission of Morganella morganii.

The onset of Morganella morganii infection within the first 72 h after birth has only been reported on 1 occasion. The authors describe a second case in which M. morganii was cultured from both the neonate's blood and the mother's lochia.

Deep venous thrombosis associated with pulmonary tuberculosis and transient protein S deficiency.

Vascular complications associated with Mycobacterium tuberculosis infection have rarely been reported in children. We describe a case of deep venous thrombosis of the left leg in association with pulmonary tuberculosis. The patient had transient protein S deficiency and anticardiolipin IgG and IgM antibodies were also present.
