Abstract
BACKGROUND The clinical and molecular epidemiology of health care-associated Clostridium difficile infection in nonepidemic settings across Canada has evolved since the first report of the virulent North American pulsed-field gel electrophoresis type 1 (NAP1) strain more than 15 years ago. The objective of this national, multicentre study was to describe the evolving epidemiology and molecular characteristics of health care-associated C. difficile infection in Canada during a post-NAP1-epidemic period, particularly patient outcomes associated with the NAP1 strain. METHODS Adult inpatients with C. difficile infection were prospectively identified, using a standard definition, between 2009 and 2015 through the Canadian Nosocomial Infection Surveillance Program (CNISP), a network of 64 acute care hospitals. Patient demographic characteristics, severity of infection and outcomes were reviewed. Molecular testing was performed on isolates, and strain types were analyzed against outcomes and epidemiologic trends. RESULTS Over a 7-year period, 20 623 adult patients admitted to hospital with health care-associated C. difficile infection were reported to CNISP, and microbiological data were available for 2690 patients. From 2009 to 2015, the national rate of health care-associated C. difficile infection decreased from 5.9 to 4.3 per 10 000 patient-days. NAP1 remained the dominant strain type, but infection with this strain has significantly decreased over time, followed by an increasing trend of infection with NAP4 and NAP11 strains. The NAP1 strain was significantly associated with a higher rate of death attributable to C. difficile infection compared with non-NAP1 strains (odds ratio 1.91, 95% confidence interval [CI] 1.29-2.82). Isolates were universally susceptible to metronidazole; one was nonsusceptible to vancomycin. The proportion of NAP1 strains within individual centres predicted their rates of health care-associated C. difficile infection; for every 10% increase in the proportion of NAP1 strains, the rate of health care-associated C. difficile infection increased by 3.3% (95% CI 1.7%-4.9%). INTERPRETATION Rates of health care-associated C. difficile infection have decreased across Canada. In nonepidemic settings, NAP4 has emerged as a common strain type, but NAP1, although decreasing, continues to be the predominant circulating strain and remains significantly associated with higher attributable mortality.

Abstract
Reporting of severe invasive group A streptococcal disease (IGAS) has increased in Canada over the past decade, highlighting the importance of optimal chemoprophylaxis and management strategies. Canadian guidelines have had variable uptake across Canada. This practice point updates relevant aspects of these guidelines, with a focus on chemoprophylaxis of contacts of IGAS cases and clinical management of IGAS. The importance of penicillin in treating group A streptococcal disease is reaffirmed, and the role of clindamycin is discussed. In situations in which chemoprophylaxis may be considered, preferred agents are summarized.

Abstract
The benefits of human immunodeficiency virus (HIV) testing in pregnancy, when combined with appropriate maternal antiretroviral therapy and intrapartum and postnatal prophylaxis, are well established. The vertical rate of transmission of HIV in North America is now well below 2%. Efforts must continue to ensure that these benefits are sustained. Women who have received little or no prenatal care and those who present for delivery with unknown HIV status need immediate testing. As more infants are exposed to antiretroviral agents, strategies need to be implemented to ensure adequate follow-up of these infants. Issues relating to the identification of HIV-exposed infants are highlighted.

Abstract
Transmission of infection in the paediatric office is an issue of increasing concern. This document discusses routes of transmission of infection and the principles of current infection control measures. Prevention includes appropriate office design and administrative policies, triage, routine practices for the care of all patients (e.g., hand hygiene; use of gloves, masks, eye protection, and gowns for specific procedures; adequate cleaning, disinfection, and sterilization of surfaces and equipment, including toys; and aseptic technique for invasive procedures), and additional precautions for specific infections. Personnel should be adequately immunized, and those infected should follow work-restriction policies.

Abstract
When children sustain injuries from needles discarded in public places, concerns arise about possible exposure to blood-borne viruses. The risk of infection is low, but assessment, counselling, and follow-up of the injured child are needed. This statement reviews the literature concerning blood-borne viral infections after injuries from needles discarded in the community, and provides recommendations for the prevention and management of such incidents.

Abstract
BACKGROUND Chronic postsurgical pain (CPSP) affects half a million children annually in the United States, with dire socioeconomic consequences, including long-term disability into adulthood. The few studies of CPSP in children are limited by sample size, follow-up duration, non-homogeneity of surgical procedure and factors evaluated. METHODS In a prospective study of 144 adolescents undergoing a single major surgery (spine fusion), we evaluated demographic, perioperative, surgical and psychosocial factors as predictors of a continuum of postsurgical pain: immediate, pain maintenance at 2-3 months (chronic pain/CP) and persistence of pain a year (persistent pain/PP) after surgery. RESULTS We found an incidence of 37.8% and 41.8% for CP and PP. CP and acute pain were both significant predictors for developing PP (p-value <0.001 and 0.003). Preoperative pain and higher postoperative opioid requirement was significantly associated with CP (p = 0.015, p = 0.002), while Childhood Anxiety Sensitivity Index (p = 0.002) and surgical duration (p = 0.014) predicted PP. The final regression models had reasonable predictive accuracy (c-statistic of 0.73 and 0.83 for CP and PP, respectively). Anxiety scores and catastrophizing for child and parent were found to be significantly correlated (p = 0.005, p = 0.013 respectively). Pain trajectories revealed that 65% of patients who developed PP reported CP and high pain trends; however, 33% of those who developed PP could not be identified using solely pain criteria. CONCLUSION Persistent postsurgical pain in children is a significant problem. It can be predicted in part by combinations of psychological and clinical variables, which may provide evidence-based measures to prevent development of CPSP in the future. SIGNIFICANCE In a homogeneous cohort of adolescents undergoing spine fusion, we report a high incidence of persistent postsurgical pain (41.8%) predicted by child anxiety, perioperative pain, and surgical duration. Our results stress timely preventive and therapeutic strategies.

Abstract
OBJECTIVE To provide an insight into the presentation, diagnosis and management of paediatric abdominal tuberculosis (TB) in developed countries. METHODS The records of all children at the Montreal Children's Hospital (MCH) admitted with abdominal TB between 1990 and 2014 were reviewed. An automated and manual literature search from 1946 to 2014 was performed. RESULTS (1) CASE SERIES: six cases were identified at the MCH. All were male between 5 and 17 years of age. All were from populations known to have high rates of TB (aboriginal, immigrant). Three underwent major surgical interventions and three underwent ultrasound (US) or CT aspiration or biopsy for diagnosis. (2) LITERATURE REVIEW: 29 male (64%) and 16 female subjects (36%) aged between 14 months and 18 years were identified, including the MCH patients. All patients except one were from populations with a high incidence of TB. Most presented with a positive tuberculin skin test (90%), abdominal pain (76%), fever (71%) and weight loss (68%). On imaging, 22 (49%) were classified with gastrointestinal TB with colonic wall irregularity (41%) and 19 (42%) with peritoneal TB with ascites (68%). A positive culture was obtained in 33 (73%) patients. Three cases used CT- or US-guided aspiration or biopsy to obtain tissue samples. A surgical intervention was performed in 34 (76%) children; 13 (38%) of these were for diagnosis. CONCLUSIONS Diagnosis based on clinical features (abdominal pain, fever and weight loss) and CT- or US-guided aspiration or biopsy may encourage physicians to adopt a more conservative approach to abdominal TB.

Abstract
The use of silver nitrate as prophylaxis for neonatal ophthalmia was instituted in the late 1800s to prevent the devastating effects of neonatal ocular infection with Neisseria gonorrhoeae. At that time - during the preantibiotic era - many countries made such prophylaxis mandatory by law. Today, neonatal gonococcal ophthalmia is rare in Canada, but ocular prophylaxis for this condition remains mandatory in some provinces/ territories. Silver nitrate drops are no longer available and erythromycin, the only ophthalmic antibiotic eye ointment currently available for use in newborns, is of questionable efficacy. Ocular prophylaxis is not effective in preventing chlamydial conjunctivitis. Applying medication to the eyes of newborns may result in mild eye irritation and has been perceived by some parents as interfering with mother-infant bonding. Physicians caring for newborns should advocate for rescinding mandatory ocular prophylaxis laws. More effective means of preventing ophthalmia neonatorum include screening all pregnant women for gonorrhea and chlamydia infection, and treatment and follow-up of those found to be infected. Mothers who were not screened should be tested at delivery. Infants of mothers with untreated gonococcal infection at delivery should receive ceftriaxone. Infants exposed to chlamydia at delivery should be followed closely for signs of infection.

Abstract
The Canadian Paediatric Society continues to encourage annual influenza vaccination for ALL children and youth ≥6 months of age. Recommendations from the National Advisory Committee on Immunization for the 2014/2015 influenza season include some important changes: Influenza vaccination is recommended for ALL individuals ≥6 months of age, with particular focus on those at high risk of influenza-related complications and their close contacts. Definitions of high-risk conditions and close contacts have not changed from those of 2013/2014.The preference for intranasal, live attenuated influenza vaccine (LAIV) over trivalent inactivated influenza vaccines for healthy children is restricted to individuals two to six years of age. There is insufficient evidence to recommend LAIV over trivalent inactivated influenza vaccines in older children or in children with chronic health conditions; either vaccine may be used unless there are specific contraindications.Quadrivalent influenza vaccines are expected to be available for the 2014/2015 season and may be used interchangeably with trivalent vaccines. They may offer improved protection.Trivalent or quadrivalent inactivated vaccines may be used in individuals with egg allergy; LAIV has not yet been evaluated in this population and is not recommended at this time.

Abstract
BACKGROUND Despite implementation of recommended best practices, our central line-associated bloodstream infection (CLABSI) rates remained high. Our objective was to describe the impact of chlorhexidine gluconate (CHG) bathing on CLABSI rates in neonates. METHODS Infants with a central venous catheter (CVC) admitted to the neonatal intensive care unit from April 2009 to March 2013 were included. Neonates with a birth weight of 1,000 g or less, aged less than 28 days, and those with a birth weight greater than 1,000 g were bathed with mild soap until March 31, 2012 (baseline), and with a 2% CHG-impregnated cloth starting on April 1, 2012 (intervention). Infants with a birth weight of 1,000 g or less, aged 28 days or more, were bathed with mild soap during the entire period. Neonatal intensive care unit nurses reported adverse events. Adjusted incidence rate ratios (aIRRs), using Poisson regression, were calculated to compare CLABSIs/1,000 CVC-days during the baseline and intervention periods. RESULTS Overall, 790 neonates with CVCs were included in the study. CLABSI rates decreased during the intervention period for CHG-bathed neonates (6.00 vs 1.92/1,000 CVC-days; aIRR, 0.33 [95% confidence interval (CI), 0.15-0.73]) but remained unchanged for neonates with a birth rate of 1,000 g or less and aged less than 28 days who were not eligible for CHG bathing (8.57 vs 8.62/1,000 CVC-days; aIRR, 0.86 [95% CI, 0.17-4.44]). Overall, 195 infants with a birth weight greater than 1,000 g and 24 infants with a birth weight of 1,000 g or less, aged 28 days or more, were bathed with CHG. There was no reported adverse event. CONCLUSIONS We observed a decrease in CLABSI rates in CHG-bathed neonates in the absence of observed adverse events. CHG bathing should be considered if CLABSI rates remain high, despite the implementation of other recommended measures.

Abstract
OBJECTIVE Describe the epidemiology of central line-associated bloodstream infections (CLABSIs) in neonatal intensive care units (NICUs) participating in a standardized and mandatory CLABSI surveillance program. DESIGN Retrospective cohort. Setting. We included patients admitted (April 2007-March 2011) to 7 level II/III NICUs who developed a CLABSI (as defined by the National Healthcare Safety Network). METHODS CLABSIs/1,000 central line-days and device utilization ratio were calculated; χ(2) test, Student t test, Kruskal-Wallis, and Poisson regression were used. RESULTS Overall, 191 patients had 202 CLABSI episodes for a pooled mean rate of 4.0 CLABSIs/1,000 central line-days and a device utilization ratio of 0.20. Annual pooled mean CLABSI rates increased from 3.6 in 2007-2008 to 5.1 CLABSIs/1,000 central line-days in 2010-2011 (P - .01). The all-cause 30-day case fatality proportion was 8.9% (n = 17) and occurred a median of 8 days after CLABSI. Coagulase-negative Staphylococcus was identified in 112 (50.5%) cases. Staphylococcus aureus was identified in 22 cases, and 3 (13.6%) were resistant to methicillin. An underlying intra-abdominal pathology was found in 20% (40/202) of CLABSI cases, 50% of which were reported in the last year of study. When adjusted for mean birth weight, annual CLABSI incidence rates were independently associated with the proportion of intra-abdominal pathology (P = .007) and the proportion of pulmonary pathology (P = .016) reported. CONCLUSION The increase in CLABSI rates in Quebec NICUs seems to be associated with an increased proportion of cases with underlying intra-abdominal and pulmonary pathologies, which needs further investigation.

Abstract
BACKGROUND In developed countries, typhoid fever generally occurs in travellers or recent immigrants from endemic areas. Our aim was to describe the epidemiology of Salmonella enterica serotype Typhi infections among children presenting to a pediatric teaching hospital in Montréal, Quebec. METHODS We included all patients less than 18 years of age who presented to the Montreal Children's Hospital between 1991 and 2011 with a laboratory-confirmed diagnosis of typhoid fever (Salmonella enterica ser. Typhi isolated from blood or stool) in a retrospective case series. RESULTS During the study period, we identified 39 cases of typhoid fever (mean age of patient 7.5 yr). Four (10.3%) of these cases occurred in newly arrived immigrants shortly after their arrival in Canada (median 15.5 d). Most cases (76.9%) occurred in children who had visited friends and relatives in their home country. None of the travellers had received a vaccination against typhoid fever before their departure. All cases presented with high fever (mean temperature 40.4°C) that lasted for a mean of 15.8 days. Common accompanying symptoms included anorexia, abdominal pain, vomiting and diarrhea. All 39 isolates of S. enterica ser. Typhi were susceptible to third-generation cephalosporins, and 7 were resistant to ciprofloxacin. Ampicillin resistance occurred in 10 (25.6%) of the isolates. No deaths occurred among the study participants. INTERPRETATION Most cases of typhoid fever occurred in children who had travelled to endemic areas to visit friends and relatives. Thus, there is a role for increased awareness on the part of family physicians and pediatricians caring for these children to discuss travel-related infections during regularly scheduled appointments, because parents might not consult travel clinics or discuss their travel plans before travelling back to their home country.

Abstract
BACKGROUND The extent to which pandemic H1N1 influenza (pH1N1) differed from seasonal influenza remains uncertain. METHODS By using active surveillance data collected by the Immunization Monitoring Program, Active at 12 Canadian pediatric hospitals, we compared characteristics of hospitalized children with pH1N1 with those with seasonal influenza A. We compared demographics, underlying health status, ICU admission, and mortality during both pandemic waves versus the 2004/2005 through the 2008/2009 seasons; influenza-related complications and hospitalization duration during pH1N1 wave 1 versus the 2004/2005 through the 2008/2009 seasons; and presenting signs and symptoms during both pH1N1 waves versus the 2006/2007 through the 2008/2009 seasons. RESULTS We identified 1265 pH1N1 cases (351 in wave 1, 914 in wave 2) and 1319 seasonal influenza A cases (816 from 2006/2007 through 2008/2009). Median ages were 4.8 (pH1N1) and 1.7 years (seasonal influenza A); P < .0001. Preexisting asthma was overrepresented in pH1N1 relative to seasonal influenza A (13.8% vs 5.5%; adjusted P < .0001). Symptoms more often associated with pH1N1 wave 1 versus seasonal influenza A were cough, headache, and gastrointestinal symptoms (adjusted P < .01 for each symptom). pH1N1 wave 1 cases were more likely to have radiologically confirmed pneumonia (adjusted odds ratio = 2.1; 95% confidence interval = 1.1-3.8) and longer median length of hospital stay (4 vs 3 days; adjusted P = .003) than seasonal influenza A. Proportions of children requiring intensive care and deaths in both pH1N1 waves (14.6% and 0.6%, respectively) were not significantly different from the seasonal influenza A group (12.7% and 0.5%, respectively). CONCLUSIONS pH1N1 in children differed from seasonal influenza A in risk factors, clinical presentation, and length of hospital stay, but not ICU admission or mortality.

Abstract
Healthcare-associated infections (HAIs), important threats to patient safety, are considered differently from other adverse events. Gardam and his colleagues discuss several reasons for this and outline approaches that may bring about changes in attitudes and enhance HAI prevention. We comment on the potential preventability of HAIs, the need for improved communication strategies and the different vision of the role of infection control personnel suggested by Gardam et al. Recent developments in infection control structure and management and patient safety in Quebec are summarized.

Abstract
La transmission des infections au cabinet du pédiatre est de plus en plus préoccupante. Le présent document expose les voies de transmission des infections et les principes sousjacents aux mesures actuelles pour contrôler les infections. Pour prévenir les infections, il faut bien concevoir le cabinet et adopter des politiques administratives et de triage convenables, de même que des pratiques de base pour les soins de tous les patients (p. ex., hygiène des mains, port de gants, de masques, de lunettes de protection et d’une blouse d’hôpital pour des interventions précises; nettoyage, désinfection et stérilisation convenables des surfaces et du matériel, y compris les jouets, et techniques d’asepsie en cas d’interventions effractives) et des précautions additionnelles en cas d’infections précises. Le personnel doit avoir reçu les vaccins pertinents, et les personnes infectées doivent respecter les politiques de restriction au travail.

Abstract
OBJECTIVES Influenza is a common childhood infection that may result in hospitalization. Our objectives were to (1) determine characteristics of children hospitalized for influenza and disease manifestations and (2) obtain baseline data before implementation of new recommendations for routine immunization of young children and their caretakers against influenza. METHODS All of the children hospitalized with laboratory-confirmed influenza at 9 Canadian tertiary care hospitals during the 2003-2004 influenza season were identified from virology laboratory reports, and their charts were reviewed. RESULTS There were 505 children admitted because of influenza. Fifty-seven percent were < 2 years old. Previously healthy children accounted for 58% of all of the cases. Pulmonary and neurologic disorders were the most common underlying chronic conditions. Fever and cough were the most frequent manifestations. Seizures occurred in 9% of cases. Serious complications included myocarditis (2), encephalopathy (6), and meningitis (1). There were 3 influenza-related deaths. Mean duration of hospitalization was 5.3 days. Twelve percent of children required ICU admission, and 6% required mechanical ventilation. Antibiotic therapy was administered in 77% of cases, and 7% received anti-influenza drugs. Information on influenza vaccination was available for 84 of 154 children identified as vaccine candidates. Twenty two had received vaccine, but only 7 children had been fully immunized > 14 days before the onset of illness. CONCLUSIONS Healthy young children and children with chronic conditions are at risk for serious illness with influenza. Ongoing surveillance is needed to evaluate the impact of changing immunization recommendations on the burden of influenza illness in children.

Abstract
To assess whether pertussis-containing vaccines cause encephalitis or encephalopathy, the IMPACT network of Canadian pediatric centers screened more than 12,000 admissions for neurologic disorders between 1993 and 2002. Seven cases of encephalopathy began within 7 days after pertussis vaccination, but a more likely cause was found in each instance. No attributable case followed administration of >6.5 million doses of vaccine.

Abstract
OBJECTIVE Acellular pertussis vaccines were introduced with the promise of an improved safety profile compared with whole-cell vaccines. In 1997-1998, Canada adopted 1 combination acellular pertussis vaccine, having previously used 1 particular combination whole-cell pertussis vaccine. We hypothesized that the change would result in a decrease in hospitalization rates for seizures and reports of hypotonic-hyporesponsive episodes (HHEs) temporally related to pertussis vaccination. METHODS Active surveillance was performed between 1995 and 2001 by the Immunization Monitoring Program-Active monitors at 12 hospitals using standard case definitions. Seizures had to occur within 72 hours after immunization with a pertussis-containing vaccine or 5 to 30 days after immunization with measles-mumps-rubella vaccine. HHE episodes had to occur within 48 hours of receipt of a pertussis-containing vaccine. Poisson regression models were used to compare the average number of monthly admissions for seizures and HHEs before and after introduction of the acellular pertussis vaccine. RESULTS We found a 79% decrease in febrile seizures associated with receipt of pertussis vaccine but no significant decrease in febrile seizures temporally related to measles-mumps-rubella between 1995-1996 and 1998-2001. There was a 60% to 67% reduction in HHEs associated with pertussis-containing vaccines between the same time periods, depending on case definition. CONCLUSIONS The risks of febrile seizures and HHEs after pertussis-containing vaccine declined significantly with the introduction of acellular pertussis vaccine in Canada. Active surveillance systems are important for detecting trends in uncommon adverse events after routine immunizations.

Abstract
OBJECTIVES To determine the rates of surgical-site infections (SSIs) after spinal surgery and to identify the risk factors associated with infection. DESIGN SSIs had been identified by active prospective surveillance. A case-control study to identify risk factors was performed retrospectively. SETTING University-associated, tertiary-care pediatric hospital. PATIENTS All patients who underwent spinal surgery between 1994 and 1998. Cases were all patients who developed an SSI after spinal surgery. Controls were patients who did not develop an SSI, matched with the cases for the presence or absence of myelodysplasia and for the surgery date closest to that of the case. RESULTS There were 10 infections following 125 posterior spinal fusions, 4 infections after 50 combined anterior-posterior fusions, and none after 95 other operations. The infection rate was higher in patients with myelodysplasia (32 per 100 operations) than in other patients (3.4 per 100 operations; relative risk = 9.45; P < .001). Gram-negative organisms were more common in early infections and Staphylococcus aureus in later infections. Most infections occurred in fusion involving sacral vertebrae (odds ratio [OR] = 12.0; P = .019). Antibiotic prophylaxis was more frequently suboptimal in cases than in controls (OR = 5.5; P = .034). Five patients required removal of instrumentation and 4 others required surgical debridement. CONCLUSIONS Patients with myelodysplasia are at a higher risk for SSIs after spinal fusion. Optimal antibiotic prophylaxis may reduce the risk of infection, especially in high-risk patients such as those with myelodysplasia or those undergoing fusion involving the sacral area.

Abstract
The role of vitamin E deficiency in the development of retinal pigment epithelial dystrophy was investigated in 11 cocker spaniels and four other dogs. The concentration of alpha-tocopherol was measured by high performance liquid chromatography in plasma samples obtained from the affected dogs and from 28 ophthalmoscopically normal, healthy control dogs. The mean (sd) plasma alpha-tocopherol concentration in the normal dogs was 20.2 (7.1) microg/ml, compared with 1.14 (0.67) microg/ml in the 11 affected cocker spaniels. The difference between the two groups remained highly significant when the alpha-tocopherol concentrations were expressed relative to the concentrations of the plasma lipids cholesterol and triglycerides. Low plasma concentrations of alpha-tocopherol were observed in the four affected dogs of other breeds, but the finding was not so consistent. The plasma lipid concentrations were normal in the affected dogs. The deficiency of alpha-tocopherol in the affected dogs appeared to be primary, because there was no clinical, biochemical or pathological evidence of underlying disease, or any indication of a dietary deficiency which might have contributed to the low concentrations of alpha-tocopherol.

Abstract
Young children readily transmit and acquire nosocomial infections. Children are also vulnerable to endogenous infections as a result of the breakdown of their normal defences by disease, invasive procedures or therapy. The increasing acuity of illness in hospitalized children and therapeutic advances have resulted in a patient population that is increasingly at higher risk for nosocomial infections. Antibiotic resistance has emerged as a problem in some paediatric hospitals, usually in intensive care and oncology units. Infection rates are the highest in neonatal and paediatric intensive care units (where bloodstream infections are the most frequent), and are usually associated with intravascular devices. On general paediatric wards, respiratory and gastrointestinal infections predominate, reflecting the occurrence in the community. The surveillance of nosocomial infections identifies priorities for infection control activities and permits evaluation of interventions.The prevention of transmission between patients and to personnel requires that certain measures be taken with all patients, and that additional precautions be taken with some infections, based on the route of transmission. The prevention of transmission from personnel involves ensuring that personnel are appropriately immunized and counselled about working with infections. The prevention of nosocomial infection also involves control of visitors, appropriate management of invasive procedures and devices, sterilization and disinfection of equipment, provision of a clean environment and adequate staffing. Severely immunocompromised children require extra protection, including ventilation systems that reduce the risk of exposure to filamentous fungi. Infection control in paediatrics is an evolving field that must adapt to changes in the paediatric patient population and in health care technology.
