Case Reports
Lupus anticoagulants in two children--bleeding due to nonphospholipid-dependent antiprothrombin antibodies.
We describe two children with significant bleeding: one with multiple ecchymoses and the other with scrotal bleeding. In both patients, the activated partial thromboplastin time (APTT) was prolonged, with positivity for lupus anticoagulants (LA). However, the Owren prothrombin time (PT), usually insensitive for LA, was also prolonged. The presence of LA is associated with diverse clinical manifestations, with most patients being asymptomatic while others present venous or arterial thrombosis. Bleeding in conjunction with LA is rare and it is unusual to see prolongation of the Owren PT assay due to LA. An extended laboratory investigation of one of the patient's plasma revealed not only LA but also a specific nonphospholipid-dependent antiprothrombin antibody causing an acquired hypoprothrombinemia. ⋯ It is likely that the low prothrombin activity and not the LA caused the bleeding. The bleeding signs and symptoms in both patients subsided when the PT was normalized, although the prolonged APTT and the LA remained.

Pain management should be warranted for all children in every situation. Italian legislation proposes a model for pain assistance based on specialized tertiary centers which provide direct clinical management for complex cases and assure continuous cooperation with hospitals and family pediatricians for managing painful conditions every day. The Procedural Pain Service of the University of Padua Department of Pediatrics applies such model for procedural pain management. ⋯ Most frequently administered drug combinations were local analgesia + intravenous midazolam alone or midazolam and propofol or midazolam and propofol and ketamine; most frequently used non-pharmacological methods were distraction using cartoons and bubbles. Minor adverse events were recorded in 281 cases (2.5%), the most common being desaturation (2.1%). In conclusion, our model functions on two integrated levels, and it can be considered generally applicable as a solution for pain management.

Nutcracker syndrome (NCS) is an uncommon cause of hematuria. It refers to the compression of the left renal vein between the aorta and superior mesenteric artery. It can cause both microscopic and gross hematuria. Hematuria may be associated with left flank pain. The diagnosis of NCS is often delayed. Most patients may have symptoms for many years and non-diagnostic evaluations before accurate diagnosis can be established. It should be included in the differential diagnosis of unexplained hematuria. The diagnosis and treatment of nutcracker syndrome are discussed. ⋯ NCS is a rare but treatable clinical condition. An inclusion of this entity in the differential diagnosis of patients with unknown cause of hematuria and flank pain can achieve efficient management of this condition.

In order to compare sociodemographical data and preexisting risk medical conditions in patients requiring hospital admission for 2009 pandemic influenza A (H1N1) virus infection and those managed on an outpatient basis, a prospective observational, matched case-control study in 36 hospitals of the Spanish National Health Service was conducted from July 2009 to February 2010. Cases were patients aged 6 months to 18 years hospitalized for influenza syndrome, in whom 2009 influenza A (H1N1) virus infection was confirmed using real-time reverse-transcription polymerase chain reaction. ⋯ In a multivariate model, hospitalization was more frequent in children aged <2 years (odds ratio (OR), 13.8; 95% confidence interval (CI), 1.7-106.4), those with neurological and/or neuromuscular diseases (OR, 3.0; 95% CI, 1.1-8.2), and those whose parents had less than a secondary educational level (OR, 2.7; 95% CI, 1.4-5.2). Children aged <2 years, children with neurological diseases, and children from families with a lower educational status had a higher risk of hospitalization due to influenza A (H1N1) 2009 infection.

Randomized Controlled Trial
Efficacy of VeinViewer in pediatric peripheral intravenous access: a randomized controlled trial.
Peripheral venous access in infants and children is technically challenging, because their veins are small and located deep in subcutaneous tissue, which makes them difficult to palpate or visualize. The VeinViewer® (Luminetx Corporation, Memphis, TN, USA) is a near-infrared light device that delineates the running course of subcutaneous veins. In this study, we investigated whether the use of the VeinViewer® in infants and children facilitated peripheral venous access, especially in difficult cases. This study was a randomized, controlled trial of a convenience sample of pediatric patients between the ages of 1 month and 16 years who required peripheral venous access in the pediatric ward. Prior to randomization, difficult intravenous access (DIVA) score, a four-variable clinical prediction rule for first-attempt success, was estimated. We compared the first-attempt success rates and procedural times between the VeinViewer® group and a control group. We evaluated 111 patients: 54 in the VeinViewer® group and 57 in the control group. Patient demographics and factors related to the success of vein access were similar for both groups. The overall first-attempt success rate was 69.4%: i.e., 77/111 in the VeinViewer® group and 38/57 in the control group, a difference that was not statistically significant. However, the first-attempt success rate increased from 5/20 in the control group to 14/24 in the VeinViewer® group for difficult veins with a DIVA score greater than 4 (p=0.026). There were no significant differences in procedural time between the two groups. ⋯ The VeinViewer® facilitated peripheral venous access for pediatric patients with difficult veins, which enhanced first-attempt success rates.
