An acute viral infection may lead to death, as seen in the recent novel 2009 influenza A (H1N1) virus pandemic that rapidly spread worldwide. Hemophagocytic lymphohistiocytosis (HLH) is a systemic disorder with high mortality rates and can be triggered by various etiological agents, including viral infections. ⋯ We report an unusual case of a rapidly progressive and fatal H1N1 infection that was complicated with HLH and MOF in a previously healthy 8-year-old Asian female who initially presented with fever and abdominal pain. To enable early recognition and proper treatment, physicians should be aware of the possibility of this fatal complication, which may present with unusual initial symptoms.

Patients with acute lobar nephronia (ALN) require a longer duration of antimicrobial treatment than those with acute pyelonephritis (APN), and ALN is associated with renal scarring. The aim of this study was to provide an understanding of ALN by comparing the clinical features of pediatric patients with ALN and APN. ⋯ The majority of clinical manifestations, laboratory findings, and microbiological features are similar between patients with ALN and APN. Clinicians should keep a high index of suspicion regarding ALN, particularly for those with ultrasonographic nephromegaly, initial higher CRP, nausea/vomiting, and fever for > 5 days after antimicrobial treatment.
