Clinical recommendations for the inpatient management of lower respiratory tract infections in children and adolescents with severe neurological impairment in Germany.

Children and adolescents with severe neurological impairment (SNI) require specialized care due to their complex medical needs. In particular, these patients are often affected by severe and recurrent lower respiratory tract infections (LRTIs). These infections, including viral and bacterial etiology, pose a significant risk to these patients, often resulting in respiratory insufficiency and long-term impairments. Using expert consensus, we developed clinical recommendations on the management of LRTIs in children and adolescents with SNI. These recommendations emphasize comprehensive multidisciplinary care and antibiotic stewardship. Initial treatment should involve symptomatic care, including hydration, antipyretics, oxygen therapy, and respiratory support. In bacterial LRTIs, antibiotic therapy is initiated based on the severity of the infection, with aminopenicillin plus a beta-lactamase inhibitor recommended for community-acquired LRTIs and piperacillin-tazobactam for patients with chronic lung disease or tracheostomy. Ongoing management includes regular evaluations, adjustments to antibiotic therapy based on pathogen identification, and optimization of supportive care. Implementation of these recommendations aims to improve the diagnosis and treatment of LRTIs in children and adolescents with SNI. What is Known: • Children and adolescents with severe neurological impairment are particularly affected by severe and recurrent lower respiratory tract infections (LRTIs). • The indication and choice of antibiotic therapy for bacterial LRTI is often difficult because there are no evidence-based treatment recommendations for this heterogeneous but vulnerable patient population; the frequent overuse of broad-spectrum or reserve antibiotics in this patient population increases selection pressure for multidrug-resistant pathogens. What is New: • The proposed recommendations provide a crucial framework for focused diagnostics and treatment of LRTIs in children and adolescents with severe neurological impairment. • Along with recommendations for comprehensive and multidisciplinary therapy and antibiotic stewardship, ethical and palliative care aspects are taken into account.

[Potential Nephrotoxicity of Combination of Vancomycin and Piperacillin-Tazobactam: Recommendations from the AG ABS of the DGPI supported by experts of the GPN]. / Potentielle Nephrotoxizität der Kombinationstherapie von Vancomycin und Piperacillin-Tazobactam: Empfehlungen der AG ABS der DGPI unter Beteiligung von Experten der GPN.

The combination of vancomycin and piperacillin/tazobactam (V+P/T) is used for empirical antibiotic treatment of severe infections, especially in immunocompromised patients and those colonized with multidrug-resistant bacteria. Nephrotoxicity is a frequently observed adverse effect of vancomycin. Its risk can be reduced by therapeutic drug monitoring and adjusted dosing. Piperacillin/tazobactam (P/T) rarely causes interstitial nephritis. The results of retrospective cohort studies in children predominantly show a low, clinically irrelevant, additive nephrotoxicity (defined as an increase in creatinine in the serum) of both substances. Due to the limitations of the existing publications, the ABS working group of the DGPI and experts of the GPN do not recommend against the use of P/T plus vancomycin. Preclinical studies and a prospective study with adult patients, which evaluated different renal function tests as well as clinical outcomes, do not support previous findings of additive nephrotoxicity. Time-restricted use of V+P/T can minimize exposure and the potential risk of nephrotoxicity. Local guidelines, developed in collaboration with the antibiotic stewardship team, should define the indications for empirical and targeted use of P/T and V+P/T. When using combination therapy with V+P/T, kidney function should be monitored through clinical parameters (volume status, balancing, blood pressure) as well as additional laboratory tests such as serum creatinine and cystatin C.

Inpatient Rsv-Management 2016-2022: Epidemiology and Adherence to A Bronchiolitis Treatment Standard at a German University Children's Hospital.

BACKGROUND: This study analyzes the RSV season 2021/2022 in a referral children's hospital, compares the epidemiology and illness severity with RSV-infected inpatients from 2016 to 2020 and audits the adherence to our internal therapy standard for RSV bronchiolitis. MATERIAL AND METHODS: Inpatients with rtPCR-confirmed RSV infection (Jan. 2016 to Jan. 2022). RESULTS: The audit comprises 306 RSV inpatients, on average 50 hospitalizations per year; in 03/2020, a rapid RSV Season-Offset was observed. In the winter season 2020/2021, no patient with RSV was hospitalized. Beginning in July, we noticed a rapid increase of RSV-admissions (most cases in Sept./Oct, duration until Dec. 2021; n=53). In 2021-2022, a significant larger share needed PICU admission (9.4% vs 3.2%, p=0.040). Adherence to the internal guidance was low; only 11.8% (n=36) of all patients received supportive treatment without inhalative or systemic medications, 37% of all patients received antibiotics. CONCLUSIONS: This audit confirms the strong impact of public preventive measures directed against SARS-CoV-2 transmission on RSV epidemiology. Few weeks after easing public COVID-19 restrictions (summer 2021), RSV inpatient cases rapidly increased, lasting until Dec. 2021. The audit of bronchiolitis management revealed surprisingly low adherence to the internal guidance, despite a face-to-face educational session with the attending pediatricians in Oct. 2021. Low adherence resulted in an unnecessary exposure of RSV patients to systemic medications of questionable benefit including antibiotics.

Study draft: "UVC-You Will See" study: longer vs. shorter umbilical venous catheter (UVC) dwell time (6-10 vs. 1-5 days) in very premature infants with birth weight < 1250 g and/or gestational age < 30 weeks.

BACKGROUND: Umbilical venous catheters (UVCs) are often used in preterm infants. Their use is associated with complications (infections, clot formation, organ injury). Very preterm infants with acquired bloodstream infection are at a higher risk for death and important morbidities (e.g., adverse neurodevelopmental outcomes). It is standard clinical practice to remove UVCs in the first days of life. Replacement of intravenous access is often performed using percutaneously inserted central catheters (PICCs). It is unclear whether serial central line use affects the rates of catheter-related complications. METHODS: A multicenter randomized controlled trial (random group assignment) was performed in 562 very premature (gestational age < 30 weeks) and/or very low birth weight infants (< 1250 g) requiring an UVC for administration of parenteral nutrition and/or drugs. Group allocation was random. HYPOTHESIS: A UVC dwell time of 6-10 days (281 infants) is not associated with an increased rate of central venous catheter (UVC, PICC)-related complications compared to 1-5 days (281 infants), and a longer UVC dwell time will significantly reduce the number of painful, invasive procedures associated with the need for vascular access as well as radiation exposure, use of antibiotics, and medical costs. PRIMARY OUTCOME PARAMETER: The number of catheter-related bloodstream infections and/or catheter-related thromboses and/or catheter-associated organ injuries related to the use of UVC/PICC was the primary outcome. CONCLUSION: Extending the UVC dwell time may significantly reduce the number of painful invasive procedures, with the potential to positively impact not only long-term pain perception but also important social competencies (attention, learning, and behavior). Thus, the "UVC-You Will See" study has the potential to substantially change current neonatal intensive care practice.

Association of viral load with TRAIL, IP-10, CRP biomarker signature and disease severity in children with respiratory tract infection or fever without source: A prospective, multicentre cohort study.

BACKGROUND: To investigate the association of viral load (VL) with (i) tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), interferon gamma-induced protein-10, C-reactive protein, and a combinatorial score (BV score), and (ii) clinical severity. STUDY DESIGN: In this prospective, multicentre cohort substudy, children with respiratory tract infection or fever without source were enrolled. VL for influenza virus, rhinovirus, respiratory syncytial virus, and adenovirus was measured from nasopharyngeal swabs. The reference standard diagnosis was established based on expert panel adjudication. RESULTS: Of 1140 recruited patients, 333 had a virus monodetection. VL for the aggregated data set correlated with TRAIL and IP-10 levels, with the length of oxygen therapy, and inversely with the BV score. At a single viral level, only the influenza VL yielded a correlation with TRAIL, IP-10 levels, and the BV score. Children with a viral reference standard diagnosis had significantly higher VL than those with bacterial infection (p = 0.0005). Low TRAIL (incidence rate ratio [IRR] 0.6, 95% confidence interval [CI] 0.39-0.91) and young age (IRR 0.62, 95% CI 0.49-0.79) were associated with a longer hospital stay, while young age (IRR 0.33, 95% CI 0.18-0.61), low TRAIL (IRR 0.25, 95% CI 0.08-0.76), and high VL (IRR 1.16, 95% CI 1.00-1.33) were predictive of longer oxygen therapy. CONCLUSION: These findings indicate that VL correlates with biomarkers and may serve as a complementary tool pertaining to disease severity.

Expression of TRAIL, IP-10, and CRP in children with suspected COVID-19 and real-life impact of a computational signature on clinical decision-making: a prospective cohort study.

PURPOSE: We evaluated the host-response marker score "BV" and its components TRAIL, IP-10, and CRP in SARS-CoV-2 positive children, and estimated the potential impact on clinical decision-making. METHODS: We prospectively analyzed levels of TRAIL, IP-10, CRP, and the BV score, in children with suspected COVID-19. Classification of infectious etiology was performed by an expert panel. We used a 5-point-questionnaire to evaluate the intention to treat with antibiotics before and after receiving test results. RESULTS: We screened 111 children, of whom 6 (5.4%) were positive for SARS-CoV-2. A total of 53 children were included for the exploratory analysis. Median age was 3.1 years (interquartile range [IQR] 1.3-4.3), and 54.7% (n = 29) were girls. A viral and a bacterial biomarker pattern was found in 27/53 (50.9%) and 15/53 (28.3%), respectively. BV scores differed between COVID-19, children with other viral infections, and children with bacterial infections (medians 29.5 vs. 9 vs. 66; p = 0.0006). Similarly, median TRAIL levels were different (65.5 vs. 110 vs. 78; p = 0.037). We found no differences in IP-10 levels (555 vs. 504 vs. 285; p = 0.22). We found a concordance between physicians' "unlikely intention to treat" children with a viral test result in most cases (n = 19/24, 79.2%). When physicians expressed a "likely intention to treat" (n = 15), BV test revealed 5 bacterial, viral, and equivocal scores each. Antibiotics were withheld in three cases (20%). Overall, 27/42 (64%) of pediatricians appraised the BV test positively, and considered it helpful in clinical practice. CONCLUSION: Host-response based categorization of infectious diseases might help to overcome diagnostic uncertainty, support clinical decision-making and reduce unnecessary antibiotic treatment.

[Outpatient Antibiotic Prescription Rates and Mastoiditis in Children and Adolescents, Saarland, 2014-2019]. / Ambulante Antibiotika-Verordnungsrate und Mastoiditis-Fälle bei Kindern und Jugendlichen im Saarland, 2014­2019.

BACKGROUND: Infections of the respiratory tract are the main indication for outpatient antibiotic therapy in children and adolescents. In recent years the antibiotic prescription rate (APR) in the pediatric population has decreased significantly. OBJECTIVES: The aim of the retrospective mastoiditis audit in the PaedineSaar network is to investigate the incidence of inpatient acute mastoiditis (AM) in Saarland (2014-2019) regarding to the decreasing APRs in children, as well as to gather data of the clinical course of AM. METHODS: All inpatient AM cases 2014-2019 were analyzed retrospectively from 6 hospitals for pediatrics and/or otorhinolaryngology in Saarland and Trier. Children and adolescents aged 0-17 years and residing in Saarland were included in the study. RESULTS: 2014-2019 53 inpatient treated AM cases have been recorded. During the study period there was no significant increase of AM incidence (mean incidence 2014-2019: 6.1/100,000). 34% (18/53) of the patients received prehospital antibiotic treatment (main indication: acute otitis media (AOM) 15/18, 83%). At least one complication occurred in 30% of the patients (16/53). There was a slight trend to more complications in children without oral antibiotic treatment before admission (14/35 (40%) vs. 2/18 (11%) p=0.056). CONCLUSIONS: The incidence of AM leading to inpatient treatment in children in Saarland did not increase 2014-2019 despite a significant and sustained decline in the outpatient APRs. The results of this audit should be used for the development of a more standardized approach concerning the diagnostics and treatment of children with AM.

[Time to Antibiotics (TTA) - Reassessment from the German Working Group for Fever and Neutropenia in Children and Adolescents (DGPI/GPOH)]. / Time to Antibiotics (TTA) ­ Überlegungen der Arbeitsgruppe Fieber bei Granulozytopenie im Kindes- und Jugendalter (GPOH/DGPI) zu einer Neubewertung.

BACKGROUND: The current German guidance from 2016 recommends a Time to Antibiotics (TTA) of<60 min in children and adolescents with febrile neutropenia (FN). METHODS: Critical analysis of available studies and recent meta-analyses, and discussion of the practical consequences in the FN working group of the German Societies for Paediatric Oncology and Haematology and Paediatric Infectious Diseases. RESULTS: The available evidence does not support a clinically significant outcome benefit of a TTA<60 min in all paediatric patients with FN. Studies suggesting such a benefit are biased (mainly triage bias), use different TTA definitions and display further methodical limitations. In any case, a TTA<60 min remains an essential component of the 1st hour-bundle in paediatric cancer patients with septic shock or sepsis with organ dysfunction. CONCLUSION: Provided that all paediatric FN patients receive a structured medical history and physical examination (including vital signs) by experienced and trained medical personnel in a timely fashion, and provided that a sepsis triage and management bundle is established and implemented, a TTA lower than 3 hours is sufficient and reasonable in stable paediatric cancer patients with FN.

Umbilical venous catheter- and peripherally inserted central catheter-associated complications in preterm infants with birth weight < 1250 g : Results from a survey in Austria and Germany.

BACKGROUND AND OBJECTIVE: Umbilical venous catheters (UVC) and peripherally inserted central catheters (PICC) are commonly used in preterm infants but have been associated with a number of serious complications. We performed a survey in Austria and Germany to assess the use of UVCs and PICCs in preterm infants with a birth weight < 1250 g and associated rates of catheter-related adverse events. METHODS: Electronic survey of participating centers of the NeoVitaA trial. Main outcome parameter was the reported rates of UVC- and PICC-associated complications (infection, thrombosis, emboli, organ injury, arrhythmia, dislocation, miscellaneous). RESULTS: In total, 20 neonatal intensive care units (NICU) providing maximal intensive care in Austria and Germany (level I) were contacted, with a senior neonatologist response rate of 12/20 (60%). The reported rates for UVC with a dwell time of 1-10 days were bacterial infection: 4.2 ± 3.4% (range 0-10%); thrombosis: 7.3 ± 7.1% (0-20%); emboli: 0.9 ± 2.0% (0-5%); organ injury: 1.1 ± 1.9% (0-5%); cardiac arrhythmia: 2.2 ± 2.5% (0-5%); and dislocation: 5.4 ± 8.7% (0-30%); and for PICCs with a dwell time of 1-14 days bacterial infection: 15.0 ± 3.4% (range 2.5-30%); thrombosis; 4.3 ± 3.5% (0-10%); emboli: 0.8 ± 1.6% (0-5%); organ injury: 1.5 ± 2.3% (0-5%); cardiac arrhythmia: 1.5 ± 2.3% (0-5%), and dislocation: 8.5 ± 4.6% (0-30%). CONCLUSION: The catheter-related complication rates reported in this survey differed between UVCs and PICCs and were higher than those reported in the literature. To generate more reliable data on this clinically important issue, we plan to perform a large prospective multicenter randomized controlled trial investigating the non-inferiority of a prolonged UVC dwell time (up to 10 days) against the early change (up to 5 days) to a PICC.

[Update Perioperative Antibiotic Prophylaxis in Neonatology]. / Update Perioperative Antibiotikaprophylaxe in der Neonatologie.

This narrative review discusses basic principles of the perioperative antibiotic prophylaxis (PAP) in premature and at term newborns and refers to some particularities concerning the indication and dosing issues. Although this is a vulnerable patient population, the spectrum of activity should not be unnecessarily broad and the regular PAP must not be prolonged beyond 24 hours.

SARS-CoV-2 in pediatric cancer: a systematic review.

The outbreak of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in December 2019 in Wuhan challenges pediatric oncologists in an unexpected way. We provide a comprehensive overview, which systematically summarizes and grades evidence (QoE) on SARS-CoV-2 infections in pediatric cancer patients at 1.5 years of pandemic. A systematic literature search in PubMed combined with an additional exploratory literature review in other international databases was conducted to identify studies on children (aged < 18 years) with a malignant disease and COVID-19 infections. In total, 45 reports on 1003 pediatric cancer patients with SARS-CoV-2 infections were identified out of 1397 reports analyzed. The clinical course of COVID-19 was reported mild or moderate in 358 patients (41.7%), whereas 11.1% of patients showed severe COVID-19. In 12.7% of patients, chemotherapy was postponed, whereas 19% of patients with different underlying malignancies received chemotherapy during SARS-CoV-2 infection. Twenty-five patients with SARS-CoV-2 infections died, potentially related to COVID-19. CONCLUSION: Despite a favorable COVID-19 outcome in most pediatric cancer patients, the morbidity is reported higher than in children without comorbidities. However, no severe COVID-19 complications were associated to the continuation of chemotherapy in some cohort studies and reports on two patients. Therefore, the risk of cancer progress or relapse due to interruption of chemotherapy has carefully to be weighed against the risk of severe COVID-19 disease with potentially fatal outcome. WHAT IS KNOWN: • Most of pediatric patients with malignant diseases show an asymptomatic, mild or moderate clinical course of SARS-CoV-2 infection. • Current need for a basis for decision-making, whether to stop or interrupt cancer treatment in a patient infected with SARS-CoV-2, and when to continue chemotherapy. WHAT IS NEW: • Review results comprising over 1000 pediatric COVID-19 cancer patients confirm mild courses of SARS-CoV-2 infection in most patients but also show the attributable mortality is at least 10 times higher compared to reports on hospitalized children without comorbidities. • Review identifies that chemotherapy was continued despite SARS-CoV-2 positivity in 18% of patients with individual chemotherapy modification according to the clinical course of SARS-CoV-2 infection and existing comorbidities. On this basis, no severe COVID-19 complications were associated to the continuation of chemotherapy in several cohort studies and two case reports.

Multidrug-resistant organisms in paediatric palliative care patients - Prevalence, risk factors and the impact of a liberal hygiene concept.

AIM: Multidrug-resistant organisms (MDRO) deserve special attention in health-care facilities for children with life-limiting conditions because these children have an increased risk for colonisation. To avoid nosocomial transmissions to other inpatients, single-room isolation is usually recommended. In the context of paediatric palliative care (PPC), such isolation counters the aim of participation in social activities for the patients. This study aimed to determine the prevalence of MDRO, the predictive value of risk factors and the incidence of nosocomial infections and nosocomial colonisations on a PPC inpatient unit applying a special hygiene concept that enables participation in social activities through risk-adaption and barrier nursing. METHODS: Two-year surveillance with MDRO screening of all intakes (N = 386) of a PPC unit on the day of admission and discharge. To determine the predictive value of pre-defined risk factors, logistic regression analyses were calculated. Receiver operating characteristic analyses were performed to determine the predictive power of the number of risk factors on the presence of MDRO. RESULTS: The rate of MDRO colonisation at admission was 12.7%; previous positive MDRO screening was the only significant individual risk factor. Over the 2-year period, no MDRO-related nosocomial infections occurred; nosocomial colonisation incidence density was 0.6. CONCLUSION: Results demonstrate that patients with at least one risk factor have to be cared for by barrier nursing until MDRO screening results are negative. Following these guidelines prevents nosocomial MDRO transmission.

Impact of School Closures on the Proportion of Children in the COVID-19 Pandemic: An Example from the Winter Lockdown in Germany.

BACKGROUND: In addition to widely used basic hygiene measures in school, school closures are applied to contain SARS-CoV-2 spread, although the effect on the pandemic is unclear. We proposed a simple approach to disentangle the effect of school closures from other lockdown measures on the pandemic course based on publicly available data in Germany. METHODS: We used data on the number of SARS-CoV-2 cases from the onset of the pandemic to 14th April 2021. We compared the proportion of children (5-14 years old) in all cases prior to the lockdown measures, including school closure, to that during a ten-week lockdown in Germany. The total number of paediatric cases occurring during lockdown was compared to the number expected in absence of school closures. The latter was calculated based on the actual weekly number of all cases and the pre-lockdown proportion of paediatric cases. RESULTS: The proportion of children in all cases was 2.3 percentage points lower at the nadir than the proportion before the lockdown. The estimated total number of paediatric cases prevented by school closures was estimated at 13,246 amounting to 24% of the expected cases in absence of school closures. CONCLUSION: School closure during the winter lockdown reduced the number of expected SARS-CoV-2 cases in children in absence of school closures. The contribution of these prevented cases to the total population incidence is small. These data might provide the basis to model the effect of school closures in addition to basic hygiene measures on the course of the COVID-19 pandemic.

[Recommendations for SARS-CoV-2/COVID-19 during Pregnancy, Birth and Childbed - Update November 2021 (Short Version)]. / Empfehlungen zu SARS-CoV-2/COVID-19 in Schwangerschaft, Geburt und Wochenbett ­ Update November 2021 (Kurzfassung).

Since the onset of the SARS-CoV-2 pandemic, the German Society of Gynecology and Obstetrics and the Society for Peri-/Neonatal Medicine have published and repeatedly updated recommendations for the management of SARS-CoV-2 positive pregnancies and neonates. As a continuation of existing recommendations, the current update addresses key issues related to the prenatal, perinatal, and postnatal care of pregnant women, women who have recently given birth, women who are breastfeeding with SARS-CoV-2 and COVID-19, and their unborn or newborn infants, based on publications through September 2021. Recommendations and opinions were carefully derived from currently available scientific data and subsequently adopted by expert consensus. This guideline - here available in the short version - is intended to be an aid to clinical decision making. Interpretation and therapeutic responsibility remain with the supervising local medical team, whose decisions should be supported by these recommendations. Adjustments may be necessary due to the rapid dynamics of new evidence.

Meropenem Use in Pediatric Oncology - Audit on Indication, Appropriateness and Consumption Comparing Patient Derived and Pharmacy Dispensing Data.

BACKGROUND: Meropenem is an important second- or third-line antibiotic in pediatric cancer patients with febrile neutropenia (FN). Concise utilization data of meropenem in this setting is limited. It remains unclear how drug dispensing data from the hospital pharmacy correlate with data derived from patients' files. METHODS: Retrospective audit of meropenem-consumption in a University-affiliated pediatric oncology center in days of therapy (DOT)/100 inpatient days. The individual indication for meropenem was critically reviewed. The real consumption (in g/100 inpatient days) was compared with the drug amounts dispensed by the hospital pharmacy (in gram and in defined daily doses (DDD)/100 inpatient days). All patients receiving at least one dose of meropenem from 1st of April 2016 until the 30th of June 2018 were included. RESULT: Of 235 consecutive patients, 45 (19%) received meropenem, comprising 57 FN events. The probability of receiving at least one dose of meropenem was significantly higher in patients with ALL, AML, NHL and certain CNS tumors. Preceding the use of meropenem, only 5% of patients were known to be colonized with multidrug-resistant Gram-negative pathogens. Meropenem was administered as first-line treatment in 26% of all meropenem cycles, in 74% of all FN events with meropenem, Piperacillin-Tazobactam was used for initial treatment. In 5 of 57 FN events (8.8%), initial blood cultures yielded a Gram-negative pathogen. Concerning definite treatment, appropriate alternatives to meropenem with a smaller spectrum of activity would have been available in 4 cases, but a de-escalation was not performed. The median length of therapy in the meropenem group was 6 days, the corresponding median for days of therapy (DOT) was 12 days. This corresponds with combination therapy in 56% of all meropenem treatments, mostly with teicoplanin. On average, drug dispensing data from the hospital pharmacy were 1.53 times higher than real use (relying on patients' data) without a significant correlation. A higher Case-mix Index positively correlated with meropenem-consumption. CONCLUSION: The use of meropenem should become a target of antibiotic stewardship programs in order to restrict its use to certain indications and preserve its outstanding role as second- or third-line antibiotic in this vulnerable population. Irrespective of the metrics used (g or DDD/100 inpatient days), pharmacy dispensing data do not accurately depict real patient-derived data concerning meropenem use in pediatric cancer patients.

[Prospektives Audit des Gentamicin Drug Monitorings in einem Kinderkrebszentrum]. / Prospective Audit of Gentamicin Drug Monitoring Practice in a Pediatric Cancer Center.

BACKGROUND: Many pediatric cancer centers still use Gentamicin as first line combination treatment in patients with fever and neutropenia. Since 2011, our center has implemented a dosing regimen with 250 mg/m2 BSA (max. 10 mg/kg, max. 400 mg) as a single daily infusion according to the German guideline. PATIENTS AND METHODS: In this prospective audit (February 2011 to December 2019), 105 Gentamicin treatment cycles were analyzed in 66 pediatric cancer patients, focusing on adherence to the dosing regimen and the drug monitoring results. RESULTS: Adherence to the dosing regimen was high (89%). In 64% of all cycles, the Cmax (drawn 1 h after the 2nd dose) reached the target of 10-20 µg/ml. Cmax significantly correlated with dosing in mg/m2 BSA (p=0,007), but not with dosing in mg/kg (p=0,366). Age below 6 years did not influence these results. The Gentamicin Ctrough (drawn 8-10 h after the second dose) was < 2 µg/ml in 93% of all cycles without any dose correlation. None of the patients experienced Gentamicin-associated nephrotoxicity. DISCUSSION AND CONCLUSION: This prospective audit of single daily infusion Gentamicin in pediatric cancer patients without impaired renal function elicits the feasibility and safety of the dosing regimen in mg/m2 BSA according to the German guideline. Since indications for first-line gentamicin are limited, a multicenter prospective study would be advantageous to confirm these observations.

[Antibacterial Prophylaxis in Children and Adolescents Undergoing Therapy for Cancer - Statement of the Society of Pediatric Oncology and Hematology (GPOH) and of the German Society for Pediatric Infectious Diseases (DGPI) on Two Current International Guidelines]. / Antibakterielle Prophylaxe in der Pädiatrischen Hämatologie und Onkologie.

Immunocompromised children and adolescents receiving treatment for cancer have an increased risk for potentially life-threatening infectious complications such as blood stream infections with Gram-positive and Gram-negative pathogens. Therefore, several centers for Pediatric Hematology and Oncology administer antibacterial prophylaxis to these patients to lower morbidity and mortality. Two pediatric specific guidelines on antibacterial prophylaxis were recently published. One of these guidelines was drawn up by an international group of pediatric experts of Europe, North and South America and Australia. The other guideline was prepared by an European group convened at the Eighth European Conference on Infections in Leukaemia (ECIL-8). In this review article, the working groups "Infections" of the Society of Pediatric Oncology and Hematology (GPOH) and "Fever in the neutropenic host" of the German Society for Pediatric Infectious Diseases" (DGPI) summarize the available data from randomized studies, systematic reviews and meta-analyses on antibacterial prophylaxis as well of current data on the emergence of resistance and discuss methodological aspects and the recommendations of the two guidelines.

Management of the First COVID-19 Wave in 45 Pediatric Practices in Saarland.

HINTERGRUND: Das Saarland ist in der ersten Welle der COVID-19-Pandemie eines der am stärksten betroffenen Bundesländer. Niedergelassene Kinder- und Jugendärzte sind für pädiatrische Patienten und ihre Familien erste Ansprechpartner. FRAGESTELLUNG: Darstellung der Herausforderungen und Maßnahmen zur Aufrechterhaltung der Patientenversorgung sowie der Zusammenarbeit während der COVID-19-Pandemie. METHODEN: Internet-basierte Befragung der niedergelassenen Kinder- und Jugendärzte sowie papierbasierte Befragung von nicht-ärztlichem Assistenzpersonal der Kinder- und Jugendarztpraxen im Saarland. ERGEBNISSE: Inhaber von 85% sowie Assistenzpersonal aus 81% der Praxen nahmen teil. Für 71% der Praxisinhaber bzw. 48% des Assistenzpersonals bestand ein erhöhtes persönliches Ausfallrisiko als Risikogruppenangehörige oder aufgrund von Betreuungsverpflichtungen. Es kam aber nur zu wenigen tatsächlichen Ausfällen. 85% halten die Hygiene- und Arbeitsschutzempfehlungen für sinnvoll, aber nur 32% stand bei Pandemiebeginn die notwendige Schutzausrüstung zur Verfügung. 89% der Praxen haben Ihr Praxis- und Patientenmanagement in der Pandemie umgestellt. Es wird ein deutlicher Verbesserungsbedarf in der Pandemievorbereitung (77%) und -bewältigung (61%), aber auch in der Zusammenarbeit mit dem öffentlichen Gesundheitswesen (59%) sowie mit Kindertagesstätten und Schulen (77%) gesehen. SCHLUSSFOLGERUNG: Die erste Welle der Pandemie hat die Praxen vor erhebliche Herausforderungen gestellt, die durch betrieblich-funktionelle Umstrukturierung und -organisation bewältigt wurden. Jedoch wird eine bessere Pandemievorbereitung und Unterstützung bei der Bewältigung einschl. verbesserter Zusammenarbeit mit den Gesundheitsämtern und Kinderbetreuungseinrichtungen gefordert.

Persistent aseptic meningitis in a child-think patch.

BACKGROUND: In patients with neurosurgical interventions requiring dura reconstruction, the use of bovine graft material may be required. PATIENTS AND METHODS: Case report. RESULTS: We present a 12-year-old girl with a profound graft reaction with severe neurologic symptoms mimicking post-neurosurgical bacterial meningitis after resection of an infra-tentorial brain tumour. CONCLUSION: It is important to take into consideration this rare clinical entity in children and adults after dura reconstruction using allogenic graft (bovine) material in order to avoid the unnecessary use of antibiotics and antiviral drugs.
