In a US cohort of 70 children with CNO, coexisting autoimmunity was a risk factor for multifocal involvement and treatment with immunosuppressive agents. Disease-modifying antirheumatic drugs and biologics were more likely to lead to clinical improvement than NSAIDs.

Although results are mixed, the highest level of evidence suggests that antiviral therapy confers a protective benefit on neonates with hearing loss and symptomatic CMV. Cochlear implantation can result in advancement of speech and language skills, but there are mixed results compared with non–CMV-infected patients.

We present a case of cat-scratch disease in a 9-year-old girl, complicated by encephalopathy and seizures. Bartonella (formerly Rochalimaea) henselae is the causative agent in cat-scratch disease; methods now available for detection of this pleomorphic, gram-negative bacterium, including polymerase chain reaction amplification and indirect fluorescence antibody testing, may lead to changes in standard criteria used to verify a diagnosis of cat-scratch disease.

We report on 5 neonates with obstructive urinary tract candidiasis in whom percutaneous nephrostomy had a major role in management. The advantages of percutaneous nephrostomy in this setting include prompt drainage of the obstructed renal pelvis or ureter, direct access to obtain specimens from the renal pelvis to confirm the diagnosis, direct irrigation of the fungus balls with amphotericin B and an access route for fragmentation of fungus balls by guide wire manipulation. In 3 cases percutaneous placement of the nephrostomy tube was successful in obtaining and maintaining access to the renal pelvis, while in 2 surgical intervention was required because of problems maintaining placement of the percutaneous catheters. Percutaneous nephrostomy with antegrade amphotericin B irrigation, coupled with systemic antifungal therapy, is the mainstay of treatment. The usefulness of ultrasonography in the early diagnosis of renal candidiasis also is emphasized.
