The aims of this study were to assess the incidence and risk factors of major central venous catheter (CVC)-related complications in a large cohort of children affected by oncological, hematological, or immunological diseases in a 7-year prospective observational study at a single center. Nine hundred fifteen CVCs were inserted in 748 children for a total period of 307,846 CVC-days. Overall, 298 complications were documented with a complication rate of 0.97/1,000 CVC-days: 105 mechanical complications (dislocations 0.30/1,000 CVC-days, ruptures 0.04/1,000 CVC-days), 174 infections (bloodstream infections 0.46/1,000 CVC-days, tunnel infections 0.10/1,000 CVC-days), and 19 thrombosis (0.06/1,000 CVC-days). Significant risk factors were: diagnosis of acute lymphoblastic leukemia (ALL) and age

Clinical features and outcome of 2009 H1N1 influenza virus in the paediatric setting is ill-defined. The epidemiologic and clinical features of children with confirmed H1N1 influenza virus infection admitted to an Italian tertiary paediatric hospital from August through December 2009 were evaluated. A total of 63 children (mean age 4.3 years) were studied; of these, 29 (46%) had chronic underlying diseases. The most frequent symptoms and signs at admission were fever (97%), cough (60%) and respiratory disturbances (24%). Forty patients (63.5%) had H1N1-related complications: 32 (51%) pulmonary diseases, three (5%) neurological disorders, such as acute encephalitis or acute disseminated encephalomyelitis, and two (3%) haematological alterations. Three patients were admitted to the Intensive Care Unit. Most children (81%) were treated with oseltamivir: one developed rash during treatment; no other adverse events were noticed. All children survived without sequelae. In conclusions, 2009 H1N1 influenza virus infection in children is associated with a wide spectrum of clinical manifestations. Neurological disorders are not exceptional complications. Oseltamivir therapy seems safe also in infants.

Tuberculosis (TB) is one of the leading causes of death worldwide. Over the last decades, TB has also emerged in the pediatric population. Epidemiologic data of childhood TB are still limited and there is an urgent need of more data on very large cohorts. A multicenter study was conducted in 27 pediatric hospitals, pediatric wards, and public health centers in Italy using a standardized form, covering the period of time between 1 January 2010 and 31 December 2012. Children with active TB, latent TB, and those recently exposed to TB or recently adopted/immigrated from a high TB incidence country were enrolled. Overall, 4234 children were included; 554 (13.1%) children had active TB, 594 (14.0%) latent TB and 3086 (72.9%) were uninfected. Among children with active TB, 481 (86.8%) patients had pulmonary TB. The treatment of active TB cases was known for 96.4% (n = 534) of the cases. Overall, 210 (39.3%) out of these 534 children were treated with three and 216 (40.4%) with four first-line drugs. Second-line drugs where used in 87 (16.3%) children with active TB. Drug-resistant strains of Mycobacterium tuberculosis were reported in 39 (7%) children. Improving the surveillance of childhood TB is important for public health care workers and pediatricians. A non-negligible proportion of children had drug-resistant TB and was treated with second-line drugs, most of which are off-label in the pediatric age. Future efforts should concentrate on improving active surveillance, diagnostic tools, and the availability of antitubercular pediatric formulations, also in low-endemic countries.
