Background Post-Infectious Neurological Syndromes (PINS) are heterogeneous neurological disorders with post or para-infectious onset. PINS diagnosis is complex, mainly related to the absence of any recognized guidelines and a univocal definition. Aim of the study To elaborate a diagnostic guide for PINS. Materials and methods We retrospectively analysed patients younger than 14 years old admitted to Bambino Gesù Children’s Hospital in Rome for PINS from December 2005 to March 2018. Scientific literature using PubMed as research platform was analysed: the key words “Post-Infectious Neurological Syndromes” were used. Results A polysymptomatic presentation occurred in a percentage of 88% of the children. Motor signs and visual disturbances the most observed symptoms/signs were the most detached, followed by fever, speech disturbances, sleepiness, headache and bradipsychism. Blood investigations are compatible with inflammation, as a prodromal illnesses was documented in most cases. Normal cerebral spinal fluid (CSF) characteristics has been found in the majority of the study population. Magnetic resonance imaging (MRI) was positive for demyelinating lesions. Antibiotics, acyclovir and steroids have been given as treatment. Discussion We suggest diagnostic criteria for diagnosis of PINS, considering the following parameters: neurological symptoms, timing of disease onset, blood and CSF laboratory tests, MRI imaging. Conclusions We propose criteria to guide clinician to diagnose PINS as definitive, probable or possible. Further studies are required to validate diagnostic criteria.

Background.Nosocomial infections are still a major cause of morbidity and mortality among neonates admitted to neonatal intensive care units (NICUs).Objective.To describe the epidemiology of nosocomial infections in NICUs and to assess the risk of nosocomial infection related to the therapeutic procedures performed and to the clinical characteristics of the neonates at birth and at admission to the NICU, taking into account the time between the exposure and the onset of infection.Design.A multicenter, prospective cohort study.Patients and Setting.A total of 1,692 neonates admitted to 6 NICUs in Italy were observed and monitored for the development of nosocomial infection during their hospital stay.Methods.Data were collected on the clinical characteristics of the neonates admitted to the NICUs, their therapeutic interventions and treatments, their infections, and their mortality rate. The cumulative probability of having at least 1 infection and the cumulative probability of having at least 1 infection or dying were estimated. The hazard ratio (HR) for the first infection and the HR for the first infection or death were also estimated.Results.A total of 255 episodes of nosocomial infection were diagnosed in 217 neonates, yielding an incidence density of 6.9 episodes per 1,000 patient-days. The risk factors related to nosocomial infection in very-low-birth-weight neonates were receipt of continuous positive airway pressure (HR, 3.8 [95% confidence interval {CI}, 1.7-8.1]), a Clinical Risk Index for Babies score of 4 or greater (HR, 2.2 [95% CI, 1.4-3.4]), and a gestational age of less than 28 weeks (HR, 2.1 [95% CI, 1.2-3.8]). Among heavier neonates, the risk factors for nosocomial infection were receipt of parenteral nutrition (HR, 8.1 [95% CI, 3.2-20.5]) and presence of malformations (HR, 2.3 [95% CI, 1.5-3.5]).Conclusions.Patterns of risk factors for nosocomial infection differ between very-low-birth-weight neonates and heavier neonates. Therapeutic procedures appear to be strong determinants of nosocomial infection in both groups of neonates, after controlling for clinical characteristics.

OBJECTIVES: Because of the spread of drug-resistant Gram-positive bacteria, the use of linezolid for treating severe infections is increasing. However, clinical experience in the paediatric population is still limited. We undertook a multicentre study to analyse the use of linezolid in children. METHODS: Hospitalized children treated with linezolid for a suspected or proven Gram-positive or mycobacterial infection were analysed retrospectively. Side effects were investigated, focusing on younger children and long-term treatments. RESULTS: Seventy-five patients (mean age 6.8 years, range 7 days to 17 years) were studied. Mean ± SD linezolid treatment duration was 26.13 ± 17 days. Clinical cure was achieved in 74.7% of patients. The most frequent adverse events were diarrhoea and vomiting. Two patients had severe anaemia, two neutropenia and one thrombocytopenia. Two cases of grade 3 liver function test elevation and one case of pancreatitis were reported. The overall frequency of adverse events was similar between patients treated for >28 days and those receiving shorter treatments (30.8% versus 28.6%, P = 0.84). Children aged

As care improves many neonates with life-threatening disorders now survive. Nonetheless Nosocomial Infections (NI) are still a major cause of morbidity and mortality in NICUs. A prospective multicentric surveillance study was conducted in six Italian NICUs to describe the epidemiologic profile and determinants of NI in NICU. 1692 neonates, consecutively admitted to the NICUs from July 2000 to October 2002 and monitored for the development of NI were enrolled into the study. The standard definition criteria for NI formulated by the Centers for Disease Control in Atlanta were used. The cumulative probability and hazard ratios (HR) for the first episode of infection were estimated by the Kaplan-Meier method and the Cox model. A total of 217 neonates had 255 episodes of NI. The incidence rate of NI was 7 per 1000 patient-days. The cumulative probability of first infection was 20% (95% CI, 7.50–23.30) and 27.6% (95 CI, 23.20–32.80) at 30 and 60 days after admission to the NICU. After adjustment for the severity of illness, the main risk factors related to NI in very-low-birth-weight neonates (VLBW) were surgical procedures (HR 2.69;95% CI 0.60–12.08), nasal ventilation (CPAP) (HR, 2.51; 95% CI, 0.93–6.76), continuous enteral feeding (HR 1.89; 95% CI, 0.20–17.50), mechanical ventilation (HR, 1.70; 95%CI, 0.72–4.00) and intravenous infusions (HR 1.46; 95% CI, 0.32–6.52). Among neonates with a birth weight over 1500 g, risk factors for NI were parenteral nutrition with lipid emulsion (HR, 12.41; 95% CI, 4.19–36.78), surgical procedures (HR 2.78; 95% CI, 0.82–9.44), and intravenous infusions (HR, 2.63; 95% CI, 0.27–25.53). Risk factors for NI were related more to the severity of illness than to healthcare procedures in VLBW babies and more to medications among neonates weighing more than 1500 g at birth.
