Abstract
With improvement in the outcomes for children with cancer has come an increasing focus on minimizing the morbidity from therapeutic interventions, including surgical procedures, while continuing to have a high likelihood of cure. Thus, an appreciation for the potential complications of surgery, both acute and long term, is critical when considering the risks and benefits of any procedure performed on a child with cancer. Although not meant to be an exhaustive review, here we discuss the most common and significant surgical complications that may occur when performing diagnostic, therapeutic, or supportive procedures in children with the most common malignant solid tumors.

JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2015; 50:232-238. [PMID: 26055687 DOI: 10.1016/j.jmii.2015.04.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2014] [Revised: 03/10/2015] [Accepted: 04/18/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND The aim of this study was to elucidate risk factors for mortality after developing sepsis in pediatric patients with hematologic and malignant disorders. METHODS A total of 90 patients (43 boys, 47 girls) with various hematologic and malignant diseases who experienced sepsis between June 2006 and March 2014 were enrolled. Clinical and laboratory features of 134 episodes of sepsis observed in the 90 patients were compared between those with and without sepsis-related death which was defined as death within 14 days after sepsis. RESULTS Age at hospitalization, sex, and type of underlying disease did not differ between patients with and without sepsis-related death. Sepsis episode-based univariate analysis identified patients with a history of relapse or in a refractory state of underlying disease (p<0.01), those with high C-reactive protein concentrations (≥50 mg/L) at the beginning of fever (p<0.01), those who had undergone hematopoietic stem cell transplantation (p<0.01), and those who were forced to change initial antibiotics (p = 0.02) because of being at high risk of sepsis-related death. The former two factors were further confirmed by multivariate analysis. More than half (52.9%) the isolates from sepsis-related death were Gram-positive cocci resistant to β-lactam antibiotics, but susceptible to vancomycin. CONCLUSION It was found that a history of relapse, a refractory state of underlying disease, and high C-reactive protein concentrations at the beginning of fever were significant risk factors for mortality after developing sepsis. Survival rate of patients with risk factors raised in this study might be improved by early introduction of vancomycin.

Abstract
BACKGROUND Cancer is the second most common cause of childhood deaths in the United Kingdom and infection contributes to a quarter of all cancer-related deaths. This study aimed to estimate the risk, aetiology and outcome of bloodstream bacterial and fungal infections in children with cancer within a geographically defined region in South-West London over a 3-year period. METHODS Web-based questionnaires were completed using case records of children with positive blood cultures admitted to five London hospitals during 2009-2011. RESULTS A total of 112 children with a median age of 5.4 (IQR 3.6-11.2) years had 266 significant blood cultures during 149 infection episodes. Haematological malignancy affected 68 patients (60.7%) and solid tumours 44 (39.3%). The overall bloodstream infection rate was 1.5 episodes per 1,000 days-at-risk (95% CI, 1.2-1.8) and was similar for those with haematological malignancies and solid tumours. Most episodes were attributed to central venous catheter infection (120/149, 80.5%). Coagulase-negative staphylococci were isolated in almost half the bloodstream infections (127/266; 47.7%), while Gram-negative organisms accounted for a further quarter (64/266; 24.1%). Fungal isolates from blood were uncommon (8/112 children, 7.1%) but significantly associated with neutropenia (18/149 [12.1%] vs. 1/114 [0.9%], P = 0.0004). Six children (5.4%) died, including three (2.7%; 95% CI, 0.6-7.6%) whose deaths were infection-related. CONCLUSIONS This study provides an updated risk estimate for bloodstream infections in children with cancer and adds to the framework for developing evidence-based guidance for management of suspected infections in this highly vulnerable group.

Abstract
AIM The aim of our study was to get epidemiological information on bacterial infections in children treated for ALL and to analyse which patients have an enhanced infection risk. METHODS Episodes of suspected or confirmed infections were evaluated during the first 12 months of treatment for childhood acute lymphoblastic leukaemia (ALL). RESULTS The number of patients was 73 (43 boys). The median age was 4.6 years. A total of 179 episodes occurred, varying from none in six patients to eight in one. Bacteria were cultured in 57 episodes (31.8%), the most common being coagulase-negative staphylococci. The number of episodes fell significantly with increasing age for suspected and confirmed infections (p < 0.001 and p = 0.03). The proportion of confirmed infections was significantly higher (p < 0.001) in the first episodes. The average number of suspected infections was higher in girls than in boys (p = 0.03), but confirmed infections were not. CONCLUSION Most of the serious infections occur early in the treatment and the number of suspected and confirmed infections falls with age. Suspicion of infection is more likely in girls, but the number of confirmed infections is equal in both sexes. Coagulase-negative staphylococcus was most commonly isolated, highlighting the importance of careful handling of central venous devices.

Abstract
PURPOSE There are limited prospective data on whether the method of flushing affects the complication rate of tunnelled central venous catheters (CVCs). PATIENTS AND METHODS During a 25-month period, 203 pediatric patients who had newly placed Broviac-Hickman CVCs were randomly assigned to standard flushing with heparin solution or to experimental flushing with normal saline via a positive-pressure cap. RESULTS Two hundred twenty-one complications were recorded among 75,249 CVC-days (2.94 per 1,000 CVC-days). A higher incidence of CVC occlusion (83 v 41 episodes; P = .0002) and bacteremia (24 v 9; P = .01) were found in the experimental arm. The cumulative probability of developing at least one CVC complication was higher in the experimental arm than in the standard arm (65.1% [95% CI, 55% to 75%] v 43.8% [95% CI, 34% to 54%], respectively; P = .01). No difference was found in either the cause or the frequency of premature removal of CVCs between the two study arms. After a median follow-up of 360 days (range, 4 to 1,073), CVC survival was similar: 77% (95% CI, 66% to 84%) for the experimental arm and 69% (95% CI, 53% to 80%) for the standard arm (P = .7). The factors associated with the occurrence of CVC complication were a diagnosis of leukemia/lymphoma, double-lumen CVC, and experimental flushing. The only factor significantly associated with premature removal of a CVC was a diagnosis of leukemia/lymphoma (hazard rate, 2.3; 95% CI, 1.1 to 4.7). CONCLUSION An increased complication rate was found with normal saline flushing, but additional investigation is warranted to clarify whether it is related to saline use or to once-a-week flushing.

Abstract
Blood samples were collected for quantitative 16S rDNA analysis from the vascular access device (VAD) of patients presenting with fever at participating centres of the UK Children's Cancer and Leukaemia Group. In total, 260 of 301 episodes of fever were evaluable and were classified as probable, possible, unlikely or unclassifiable VAD-associated infection. The sensitivity of the 16S rDNA assay declined concomitantly with delays from time of presentation to sampling. The sensitivity with >0.125 pg of bacterial DNA/microL of whole blood was 80% for the 20 probable VAD-associated infections diagnosed with samples collected on the day of or day following presentation. The specificity rose with increasing amounts of bacterial DNA, from 93% with >0.125 pg, to 98% with 0.25-0.5 pg, and to 100% with >0.5 pg/microL blood. The positive predictive value (for probable or possible) was 88% (95% CI 70-98%) with 0.25 pg/microL, and 100% (95% CI 83-100%) with >0.5 pg/microL. All 18 (6.8%) episodes with >0.5 pg of bacterial DNA/microL blood were associated with positive blood cultures. Identifications derived from the DNA sequence were consistent with the blood culture identifications for 15 of the 17 episodes with a DNA sequence identification. The VAD was removed because of suspected infection in six (2.8%) of 216 episodes with <0.125 pg of bacterial DNA/microL, in one (5%) of 20 episodes with 0.125-0.25 pg/microL, in one (16.7%) of six episodes with 0.25-0.5 pg/microL, and in nine (50%) of 18 episodes with >0.5 pg/microL. A bacterial DNA concentration of >0.5 pg/microL in blood drawn through a central venous catheter at the time of fever presentation had a high positive predictive value for VAD-associated infection and predicted an increased risk of VAD removal because of suspected infection.

Abstract
Septicaemia in neutropaenic patients is predominantly due to gut translocation [endogenous septicaemia] and contamination of the central venous catheter by microorganisms not carried by the patient [exogenous septicaemia]. To control both types of infection, a protocol was implemented based on pre 1990's parenteral and enteral antimicrobials together with strict hygiene. Surveillance cultures of throat/rectum were taken to distinguish exogenous from endogenous septicaemia and enteral non-absorbable antibiotics are administered as part of selective decontamination of the digestive tract (SDD). This protocol was evaluated in a 14-bedded paediatric oncology unit over a period of 3 years. 313 Septicaemia episodes were recorded in 131 children. 28.4% of the septicaemias were caused by microorganisms associated with the unit, equivalent to 0.82 episodes per 100 patient days. Low-level pathogens such as coagulase-negative staphylococci caused more than 70% of infections. Amongst the potential pathogens, Pseudomonas species (7.8%) and Staphylococcus aureus (5.5%) were predominant. Antibiotic resistance was rare with no superinfections or outbreaks. Four patients (3%) died, two due to Candida species and two due to Pseudomonas aeruginosa. We believe that the addition of enteral non-absorbable antibiotics to systemic antibiotics maintained a low level of resistance and mortality but a randomised controlled trial is indicated to confirm these observations.

Abstract
Static electricity within sterile packaging may result in bacterial contamination of central venous catheters (CVCs) prior to insertion. To prevent this, some surgeons inject saline into the pack before opening it. This trial was designed to determine the effect of this procedure. A double blind randomised controlled trial of 47 CVCs comparing injection of 2 ml of sterile saline into the pack prior to opening with no injection was performed. Five centimetre lengths cut from the tip of the catheter before and after subcutaneous tunnelling were sent for microbiological culture. Eight catheters (17%) showed evidence of bacterial contamination prior to insertion into the vein. Two (4.2%) were contaminated prior to tunnelling and seven (14.9%) afterwards. One catheter was contaminated before and after tunnelling. All but one of the contaminating bacteria were coagulase negative staphylococci. There was no significant difference in the contamination rate between catheters from packs that had been injected (5/25) and those that had not (3/22), P = 0.56. Just under one-fifth of the catheters were contaminated with bacteria prior to insertion into the vein but this was not influenced by prior injection of saline into the pack. We conclude that there is no evidence to support the practice of injecting the catheter pack prior to opening.

Abstract
BACKGROUND Current methods for in situ diagnosis of catheter-related bloodstream infections require concurrent collection of central venous catheter (CVC) and peripheral vein (PV) blood cultures. Both the pain and inconvenience of PV cultures are undesirable. METHODS A prospective study was conducted (August 2002 to March 2004) to assess the accuracy of diagnosing catheter-related bloodstream infections based on the difference in time to detection of blood cultures drawn concurrently from 2 lumens of a multilumen CVC. This difference in time to detection between 2 lumens was compared with results of the standard criterion with paired CVC and PV blood cultures. RESULTS Twenty-one infectious episodes were categorized as catheter-related bloodstream infections and 38 as non-catheter-related bloodstream infections. With a cutoff in difference in time to detection between 2 lumens of > or =180 minutes, the sensitivity of this test to diagnose a catheter-related bloodstream infection was 61% (95% confidence interval, 39-80%) and the specificity was 94% (95% confidence interval, 82-99%). In 4 of 7 episodes with false-negative results, the colony counts in cultures from both lumens were >400 colony-forming units/mL (maximal value reported), indicating the limitation of this method when both lumens of the catheter are colonized. With the pretest probability of catheter-related bloodstream infections ranging from 28% to 54%, the positive predictive value of a difference in time to detection between 2 lumens of > or =180 minutes for diagnosis of catheter-related bloodstream infections ranged from 81% to 93% and the negative predictive value ranged from 67% to 86%. CONCLUSION Within the context of its limitations, this novel method provides an alternative for diagnosing catheter-related bloodstream infections among patients with a CVC, without PV cultures.

Abstract
BACKGROUND The use of indwelling central venous catheters (CVCs) has become commonplace in the management of children undergoing anticancer treatment. Several types of CVC are available, while information on complications observed in children is scarce. We describe the experience of two tertiary care centers in Italy that prospectively followed up three types of CVC used at both institutions over a 30-month period. PATIENTS AND METHODS Between January 2000 and May 2002, double-lumen (DL) or single-lumen (SL) Hickman-Broviac (HB) catheters, and single-lumen pressure-activated safety valve (PASV) catheters were used and prospectively evaluated. Four types of possible complication were defined a priori: mechanical, thrombotic, malfunctioning and infectious. RESULTS Four hundred and eighteen CVCs (180 SL-HB, 162 DL-HB and 76 PASV) were inserted in 368 children, for a total of 107 012 catheter days at risk of complication. At least one complication occurred while using 169 of the devices (40%): 46% of the DL-HB, 46% of the PASV and 33% of the SL-HB (P=0.02) catheters. Subjects with hematological malignancies or non-malignant diseases had significantly more complications than those with solid tumors (P <0.0001). Overall, 234 complications were documented: 93 infectious [complication rate per 1000 catheter days at risk (CR)=0.87], 84 malfunctioning (CR=0.78), 48 mechanical (CR=0.45) and nine thrombotic (CR=0.08). SL-HB had statistically fewer infectious complications, while PASV had more mechanical complications. In a multivariate regression model, the most significant risk factors for having a CVC complication were hematological disease [relative risk (RR)=3.0; 95% confidence interval (CI) 1.8-4.8] and age <6 years at CVC insertion (RR=2.5; 95% CI 1.5-4.1). As for the type of CVC, compared with SL-HB, the DL-HB catheter had a statistically significant two-fold increased risk of any complication (RR=2.1; 95% CI 1.2-3.6), while the PASV catheter had a borderline RR of 1.8 (95% CI 1.0-3.6). Analysis by tumor type showed a higher risk of any kind of complication in patients with solid malignancies who had received a DL-HB catheter as compared with an SL-HB catheter (RR=7.2; 95% CI 2.8-18.7). CONCLUSIONS CVCs may cause complications in up to 40% of patients, with type of CVC, underlying disease and patient age being the three main factors that affect the incidence of CVC-related complications. SL-HB catheters have the best performance.

Abstract
Current methods for diagnosis of catheter-related infection (CRI) are cumbersome and may require removal of the central venous catheter (CVC). A prospective study was conducted to validate the difference in time to detection (DTD) of cultures of blood samples obtained simultaneously from a peripheral vein (PV) and from the CVC for differentiation of CRI and non-CRI. During a 15-month period, 9 episodes were categorized as CRI and 24 as non-CRI. The median DTD for patients with CRI was significantly higher than that for patients with non-CRI (457 vs. -4 min; P<.001). The optimum cutoff point for diagnosis of CRI was a DTD of > or =120 min (sensitivity, 88.9%; specificity, 100%). With pretest probability of CRI ranging from 28% to 54%, the positive predictive value of a DTD of > or =120 min for the diagnosis of CRI was 100%; the negative predictive value was 89%-96%. On the basis of findings from this study, which is the largest, to date, to involve pediatric patients with tunneled CVCs and the first to use paired quantitative blood cultures as a "criterion standard," DTD was found to be a simple, reliable tool for diagnosis of CRI in hospitals that use continuously read blood culture systems.

Abstract
We carried out a retrospective study on the infection rate--in episodes per 100 person months at risk (p/m/r)--of septicaemia and invasive mycoses in children with solid tumours treated at a single institution between 1985 and 1996. Among 982 patients, accounting for 8108 p/m/r, 257 infectious episodes were documented, for an infection rate of 3.2. The infection rate for "intensive" treatment was greater than that for "less intensive" treatments, 3.7 compared with 0.5, respectively; P<0.001. 58% of infectious episodes were associated with neutropenia, 22% were megatherapy-related, and 39% were related to central venous catheter (CVC), while in 13% of the episodes no risk factor was identified. Of the episodes, single organism Gram-positive bacteraemias accounted for 62%, single organism Gram-negative for 23%, multiple organism bacteraemias for 7%, invasive mycoses for 4%, and isolated fungaemias for 4%. The infection rate for Gram-positive organisms decreased significantly over time (-5.9% per year; P<0.01), but increased for the Gram-negative organisms (+3.4% per year; P=0.4). This study demonstrates that the risk of bacteraemia increases in parallel with the treatment intensity, and that a considerable number of children with solid tumours develop bacteraemia in the absence of an identifiable risk factor.

Abstract
OBJECTIVE To evaluate the insertion and use of implantable central venous accesses in medical oncology at the Institute Salah Azaïz. METHODS From January 1992 to June 2000, 205 patients including 179 adults (118F/61M) and 26 children aged 7 months to 72 years (mean 37 years) required the insertion of an implantable port (IP). Tumoral pathology was dominated by metastatic breast carcinoma (93/179), digestive cancer (42/179) and paediatric cancer (26 cases). RESULTS Excluding 3 initial failures, we inserted 205 IP for 202 patients. The supraclavicular anatomic way (Yoffa) was used in 156/205 cases and the subclavicular (Aubaniac) for the resting 32 cases with a jugular conversion in 17 cases. Initial complications were represented by 6 arterial puncture (2.9%), 3 pneumothorax (1.5%) and 1 catheter migration in the right pulmonary artery. Median life duration of the material was 210 days (3 to 1460 days) for adults and 185 days (3 to 1460 ays) for children. Mean life duration for the 205 IP was 240 days +/- 239 (3 to 1460 days) with a total of 49,200 IP-days. We explanted 17 IP for infection (8 cases), cutaneous ulceration (8 cases) and actinomycin extravasation (1 case). We observed 6 cases (2.9%) of subclavian and jugular thrombosis treated by anticoagulants and conservation management of the port. Presently, 58 patients are alive with IP in place. CONCLUSION Implantable ports represent a useful option in medical oncology for patients treated with prolonged chemotherapy and adjuvant treatments such as antibiotics, transfusion. This method allows a good comfort for the patients and also the treating team but requires a prealable training for the nursing team.

Abstract
STUDY OBJECTIVES To determine the magnitude of infection rate and antimicrobial resistance in a pediatric ICU (PICU), and to evaluate the efficacy of using broad-spectrum antibiotics. DESIGN A 3-month, prospective, observational cohort audit. SETTING A 12-bed tertiary, referral PICU. PATIENTS OR PARTICIPANTS All children admitted to the PICU for > 72 h. INTERVENTIONS Surveillance cultures of throat and rectum on admission and once weekly thereafter. MEASUREMENTS AND RESULTS Of the 150 admissions during the 3-month period, a total of 52 patients (24 girls and 28 boys) requiring mechanical ventilation for a minimum of 3 days were enrolled in the audit. The median age and interquartile range (IQR) was 17 months (IQR, 5.8 to 63); length of stay, 6.5 days (IQR, 4 to 13); ventilation days, 5 (IQR, 3 to 11); pediatric risk of mortality score, 14 (IQR, 9 to 19); and risk of mortality, 0.03 (IQR, 0.014 to 0.087). Fifteen patients (29%) developed 21 infections, mainly lower-airway infections and septicemias. Of the 52 children, 7 children carried multidrug-resistant bacteria and 3 patients progressed to develop four infections with those resistant bacteria. Of the seven carriers, six patients carried gentamicin-resistant Klebsiella. Methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae and gentamicin-resistant Pseudomonas aeruginosa each were carried by one child. Six of those nine resistant isolates were present in the admission flora. Despite the potent combination of piperacillin/tazobactam and amikacin, three children acquired the multidrug-resistant Klebsiella while in the PICU and became nosocomial carriers. CONCLUSIONS Only surveillance cultures allow the distinction between import of multidrug-resistance and resistant bacteria acquired while in PICU. In this study, two thirds of the resistant isolates were imported. The introduction of newer potent systemic antibiotic combinations failed to control the endemic reservoir of multidrug-resistant Klebsiella and suggests that such policies have little impact.

Abstract
OBJECTIVES To review infection and sepsis in patients with cancer and to provide an overview of controversies and research-based practices of infectious complications and management strategies. DATA SOURCES Research studies, review articles, web sites, and consensus documents. CONCLUSIONS Traditional assumptions about infection and its optimal management are redefined by research regarding transfusion and catheter-related infections, prophylactic antibiotic administration, use of growth factors, and antimicrobial therapy regimens. IMPLICATIONS FOR NURSING PRACTICE Infection is still the most common source of morbidity and mortality among cancer patients. The importance of recognizing high-risk patients, implementing infection prevention practices, and prompt intervention for infection symptoms has been established.

Abstract
A prospective cohort study was undertaken with two end points: (i) to compare the 48 h time cut-off with the carrier state criterion for classifying infections, and (ii) to determine a time cut-off more in line with the carrier state concept. All patients admitted to the intensive care unit and expected to require mechanical ventilation for a period > or = 3 days were enrolled. Surveillance cultures of throat and rectum were obtained on admission and thereafter twice weekly to distinguish micro-organisms that were imported into the intensive care unit from those acquired during the stay in the unit. A total of 117 patients with median age of 61 years and median Simplified Acute Physiology Score II of 42, were included in the study. Of these patients, 48 (41%) developed a total of 74 infection episodes. Using the 48 h cut-off point, 80% of all infections were classified as ICU-acquired. According to the carrier state criterion, 44 infections (60%) were of primary endogenous development caused by micro-organisms imported into the intensive care unit. Seventeen secondary endogenous (23%) and 13 exogenous (17%) infections were caused by bacteria acquired in the unit. The carrier state classification allowed the transfer of 49% of infections from the ICU-acquired group into the import group. A time cut-off of nine days was found to identify ICU-acquired infections better than two days. These data suggest that monitoring of carriage of micro-organisms may be a more realistic approach to classify infections developing in the intensive care unit.

Abstract
The advent of aggressive treatment protocols and the development of new techniques and procedures now require that the pediatric surgeon be an integral part of all aspects of pediatric oncology care. Supportive care issues, rather than primary tumor management decisions, now dominate the pediatric surgeon's experience and range from managing the different types of vascular access devices and their complications to assessing the surgical implications of the toxic complications of current chemotherapy protocols. New treatments such as bone marrow transplantation have presented new challenges to the pediatric surgeon, while new techniques such as minimally invasive surgery have dramatically improved our ability to render compassionate and more effective care to our patients as they undergo these potentially toxic treatment regimens.

Abstract
Although there have been many studies evaluating risk factors for catheter-related infections in children with cancer, none have examined whether swimming presents such a risk. Families of children with cancer were asked about specific swimming practices and central line care to determine whether there is an association between swimming and infection. Parents completed a self-report questionnaire and medical records were reviewed to document catheter-related intraluminal, tunnel, and exit-site infections. Ninety-one children with a total of 101 tunneled catheters participated in the study. Forty-nine children with a total of 50 catheters were swimmers; 46 children with 51 catheters were nonswimmers (four children had two catheters and swam with one catheter but not the other, therefore, these children were counted twice). There were no statistically significant differences in rates of catheter-related infections between the two groups (0.04/catheter-month in swimmers versus 0.25/in non-swimmers, relative risk; RR = 1.6, p = .16). When the analysis was confined to summertime infections per summertime catheter month, there were no significant differences in the rates of infections per summer month (0.06 for swimmers vs. 0.05 for non-swimmers, RR = 1.4; p = .50). When the analyses were performed to compare frequent swimmers with infrequent/non-swimmers, once again there were no differences found in rates of catheter-related infections between the two groups. These results suggest that swimming does not increase the risk of catheter-related infections in children with tunneled catheters.

Abstract
Central venous access has been widely used in the treatment of different categories of patients but it is associated with a wide range of complications. Different catheters, approaches and techniques have been employed to minimize those complications related to catheter insertion as well as those related to the prolonged use of catheters. This article reviews the technical aspects of central venous catheterization and associated complications.
