RESUMO

Introduction: In neonatology, the accurate determination of vital parameters plays a pivotal role in monitoring critically ill newborns and premature infants, as well as aiding in disease diagnosis. In response to the limitations associated with contact-based measurement methods, substantial efforts have been directed toward developing contactless measurement techniques, particularly over the past decade. Methods: Building upon the insights gained from our pilot study, we realized a new investigation to assess the precision of our imaging photoplethysmography-based system within a clinical environment of the neonatal intermediate care unit. We conducted measurements in 20 preterm infants or newborns requiring therapeutic interventions. As a point of reference, we employed a conventional pulse oximeter. To analytically predict measurement artifacts, we analyzed the potential influence of confounding factors, such as motion artifacts, illumination fluctuations (under- and overexposure), and loss of region of interest prior to heart rate evaluation. This reduced the amount of data we evaluated for heart rate to 56.1% of its original volume. Results: In artifact-free time segments, the mean difference between the pulse oximetry and the imaging photoplethysmography-based system for 1 s sampling intervals resulted in -0.2 bpm (95% CI -0.8 to 0.4, LOA ±â€…12.2). For the clinical standard of 8 s averaging time, the mean difference resulted in -0.09 bpm (95% CI -0.7 to 0.6, LOA ±â€…10.1). These results match the medical standards. Discussion: While further research is needed to increase the range of measurable vital parameters and more diverse patient collectives need to be considered in the future, we could demonstrate very high accuracy for non-contact heart rate measurement in newborn infants in the clinical setting, provided artifacts are excluded. In particular, performing a priori signal assessment helps make clinical measurements safer by identifying unreliable readings.

RESUMO

Background: Randomized controlled trials have indicated reduced mortality rates in very preterm infants assigned to high compared to low oxygen saturation (SpO2) target levels, accompanied by higher rates of retinopathy of prematurity and bronchopulmonary dysplasia. However, the benefit-to-harm ratio may depend on the local background mortality risk. We therefore aimed to quantify the risk-benefit ratios of different SpO2 target ranges in 10 tertiary newborn intensive care units (NICUs) in East Germany. Methods: In a retrospective multicenter study, 1,399 infants born between 2008 and 2012 at a gestational age between 24 0/7 and 27 6/7 weeks and with a birthweight below 1,250 g were grouped according to the hospital's target SpO2 range [high oxygen saturation group (HOSG) above 90%], low oxygen saturation group (LOSG) below 90%] and the compliance of units with their target SpO2 range. The association between neonatal morbidities, neurodevelopmental outcomes, selected treatment strategies, and target SpO2 ranges was calculated using chi-squared and Mann Whitney U tests. Results: Nine of the ten participating NICUs met their SpO2 target ranges. Five units were considered as HOSG, and five units were considered as LOSG. Necrotizing enterocolitis and intraventricular hemorrhage grade ≥ 2 occurred significantly more frequently in the HOSG than in the LOSG (8.4% vs. 5.1%, p = 0.02; and 26.6% vs. 17.7%, p < 0.001). No significant differences in the mortality rate and the rate of retinopathy of prematurity were found. Conclusion: In our patient population, a lower SpO2 target range was not associated with increased safety risks in extremely preterm infants. We cannot be sure that our outcome differences are associated with differences in oxygen saturations due to the retrospective study design and the differences in site practices.

RESUMO

BACKGROUND: Renal oligohydramnios (ROH) describes an abnormally low volume of amniotic fluid (AF) during pregnancy. ROH is mostly caused by congenital fetal kidney anomalies. The ROH diagnosis frequently implies an increased risk of peri- and postnatal fetal mortality and morbidity. The present study aimed to evaluate the impact of ROH on pre-and postnatal development in children with congenital kidney anomalies. METHODS: This retrospective study included 168 fetuses with anomalies in the kidney and urinary tract. Based on the amount of AF measured by ultrasound, patients were divided into three groups: normal amniotic fluid (NAF), amniotic fluid in the lower normal range (LAF), and ROH. These groups were compared with respect to prenatal sonographic parameters, perinatal outcomes, and postnatal outcomes. RESULTS: Among the 168 patients with congenital kidney anomalies, 26 (15%) had ROH, 132 (79%) had NAF, and 10 (6%) had LAF. Of the 26 families affected by ROH, 14 (54%) decided to terminate pregnancy. Of 10 live-born children in the ROH group, 6 (60%) survived the observation time; of these, 5/6 presented with chronic kidney disease, stages I-III, at their last examination. The main differences in postnatal development between the ROH group and the NAF and LAF groups were: restricted height and weight gain, respiratory issues, complicated feeding, and the presence of extrarenal malformations. CONCLUSIONS: ROH is not a mandatory indicator of severe postnatal kidney function impairment. However, children with ROH have complicated peri-and postnatal periods, due to the presence of concomitant malformations, which must be considered in prenatal care. A higher resolution version of the Graphical abstract is available as Supplementary information.

RESUMO

PURPOSE: Ewing's sarcoma is a highly malignant childhood tumour whose outcome has hardly changed over the past two decades despite numerous attempts at chemotherapy intensification. It is therefore essential to identify new treatment options. The present study was conducted to explore the effectiveness of combined inhibition of two promising targets, ATR and ribonucleotide reductase (RNR), in Ewing's sarcoma cells. METHODS: Effects of the ATR inhibitor VE821 in combination with the RNR inhibitors triapine and didox were assessed in three Ewing's sarcoma cell lines with different TP53 status (WE-68, SK-ES-1, A673) by flow cytometric analysis of cell death, mitochondrial depolarisation and cell cycle distribution as well as by caspase 3/7 activity determination, by immunoblotting and by real-time RT-PCR. Interactions between inhibitors were evaluated by combination index analysis. RESULTS: Single ATR or RNR inhibitor treatment produced small to moderate effects, while their combined treatment produced strong synergistic ones. ATR and RNR inhibitors elicited synergistic cell death and cooperated in inducing mitochondrial depolarisation, caspase 3/7 activity and DNA fragmentation, evidencing an apoptotic form of cell death. All effects were independent of functional p53. In addition, VE821 in combination with triapine increased p53 level and induced p53 target gene expression (CDKN1A, BBC3) in p53 wild-type Ewing's sarcoma cells. CONCLUSION: Our study reveals that combined targeting of ATR and RNR was effective against Ewing's sarcoma in vitro and thus rationalises an in vivo exploration into the potential of combining ATR and RNR inhibitors as a new strategy for the treatment of this challenging disease.

RESUMO

BACKGROUND: Probiotics are often viewed as an immunity enhancing agent. The objective of this study was to investigate whether oral administration of Escherichia coli Nissle 1917 reduces the number of infections, their duration, and severity in the first 24 months after parturition in healthy neonates. SUBJECTS AND METHODS: This prospective, confirmatory, randomised, double-blind, placebo-controlled study enrolled 567 healthy neonates from four German and two Polish sites. Neonates received 10e8 viable E. coli Nissle (n=283) or placebo (n=284) daily in the first week and every second day in week 2 and 3. After 6 and 12 months, the subjects received additional instillations on ten subsequent days. The overall efficacy was assessed by the number of infections per observation period. RESULTS: Incidence rates of infection, infection duration and severity showed no statistically significant difference between groups after 24 months. Post-hoc analyses, however, revealed a short-term benefit of E. coli Nissle four weeks after treatment start which became less pronounced after eight weeks. E. coli Nissle was safe and well tolerated. CONCLUSIONS: A long-term effect after colonising the healthy neonate´s gut with E. coli Nissle to protect against infections could not be shown. Additional studies are needed to confirm a transitory, yet clinically significant role of probiotics in the first four weeks after parturition.

RESUMO

Acute SARS-CoV-2 infections in children and adolescents are usually mild. However, they can suffer from ongoing symptoms, generally referred to as long COVID. Sleep disorders are one of the most frequent complaints in long COVID although precise data are missing. We assessed the sleep behavior of children and adolescents who presented at our outpatient clinic between January 2021 and May 2022 with the Children's Sleep Habits Questionnaire (CSHQ-DE). We compared the sleep behavior at three different time points: pre-COVID-19; post-COVID-19 at the initial presentation; and post-COVID-19 at re-presentation. Data from 45 patients were analyzed. Of those, 64% were female and the median age was 10 years (range: 0-18 years). Asymptomatic or mild COVID-19 disease was experienced in 89% of patients; 11% experienced moderate disease. The initial presentation occurred at a median of 20.4 weeks (6 weeks-14 months) after the infection. The CSHQ-DE score increased significantly from pre-COVID-19 (45.82 ± 8.7 points) to post-COVID-19 (49.40 ± 8.3 points; p ≤ 0.01). The score then normalized at re-presentation (46.98 ± 7.8; p = 0.1). The greatest changes were seen in the CSHQ-DE subscale score "daytime sleepiness". Our data showed that children and adolescents with long COVID often suffer from sleep disturbances. For most children and adolescents, these sleep disorders decreased over time without any further medical intervention aside from a basic sleep consultation.

RESUMO

Newborns and preterm infants require accurate and continuous monitoring of their vital parameters. Contact-based methods of monitoring have several disadvantages, thus, contactless systems have increasingly attracted the neonatal communities' attention. Camera-based photoplethysmography is an emerging method of contactless heart rate monitoring. We conducted a pilot study in 42 healthy newborn and near-term preterm infants for assessing the feasibility and accuracy of a multimodal 3D camera system on heart rates (HR) in beats per min (bpm) compared to conventional pulse oximetry. Simultaneously, we compared the accuracy of 2D and 3D vision on HR measurements. The mean difference in HR between pulse oximetry and 2D-technique added up to + 3.0 bpm [CI-3.7 - 9.7; p = 0.359, limits of agreement (LOA) ± 36.6]. In contrast, 3D-technique represented a mean difference in HR of + 8.6 bpm (CI 2.0-14.9; p = 0.010, LOA ± 44.7) compared to pulse oximetry HR. Both, intra- and interindividual variance of patient characteristics could be eliminated as a source for the results and the measuring accuracy achieved. Additionally, we proved the feasibility of this emerging method. Camera-based photoplethysmography seems to be a promising approach for HR measurement of newborns with adequate precision; however, further research is warranted.

RESUMO

Introduction A common problem in the treatment of threatened preterm birth is the timing and the unrestricted use of antenatal corticosteroids (ACS). This study was performed to evaluate the independent effects of the distinct timing of antenatal corticosteroids on neonatal outcome parameters in a cohort of very low (VLBW; 1000 - 1500 g) and extreme low birth weight infants (ELBW; < 1000 g). We hypothesize that a prolonged ACS-to-delivery interval leads to an increase in respiratory complications. Materials and Methods Main data source was the prospectively collected single center data for the German nosocomial infection surveillance system (KISS) between 2015 and 2018. Multivariate regression analysis was performed to determine independent effects of the ACS-to-delivery interval on the need for ventilation, surfactant or the occurrence of bronchopulmonary dysplasia, neonatal sepsis or necrotizing enterocolitis. Subgroup analysis was performed for ELBW and VLBW neonates. Results A total of 239 neonates were included. We demonstrate a significantly increased risk of respiratory distress characterized by the need for ventilation (OR 1.045; CI 1.011 - 1.080) and surfactant administration (OR 1.050, CI 1.018 - 1.083) depending on the ACS-to-delivery interval irrespective of other confounders. Every additional day between ACS and delivery increased the risk for ventilation by 4.5% and for surfactant administration by 5%. Subgroup analysis revealed significant differences of respiratory complications in VLBW infants. Conclusions Our data strongly support the deliberate use and timing of antenatal corticosteroids in pregnancies with threatened preterm birth versus a liberal strategy. When given more than 7 days before birth, each day between application and delivery increases is relevant concerning major effects on the infant. Especially VLBW preterm neonates benefit from optimal timing.

RESUMO

BACKGROUND: Post-processing software can be used in digital radiography to achieve higher image quality, especially in cases of scattered radiation. SimGrid is a grid-like software based on a Convolutional Neuronal Network that estimates the distribution and degree of scattered radiation in radiographs and thus improves image quality by simulating an anti-scatter grid. S-Enhance is an algorithm programmed to improve contrast visibility of foreign material. OBJECTIVE: The objective of this study was to evaluate the SimGrid and S-Enhance digital radiography post-processing methods for neonatology and paediatric intensive care. MATERIALS AND METHODS: Two hundred and ten radiographs from the neonatal (n = 101, 0 to 6 months of age) and paediatric (n = 109, 6 months to 18 years of age) intensive care units performed in daily clinical routine using a mobile digital radiography system were post-processed with one of the algorithms, anonymized and then evaluated comparatively by two experienced paediatric radiologists. For every radiograph, patient data and exposure data were collected and analysed. RESULTS: Analysis of different radiographs showed that SimGrid significantly improves image quality for patients with a weight above 10 kg (range: 10-30 kg: odds ratio [OR] = 6.683, P < 0.0001), especially regarding the tracheobronchial system, intestinal gas, and bones. Utilizing S-Enhance significantly advances the assessment of foreign material (OR = 136.111, P < 0.0001) and bones (OR = 34.917, P < 0.0001) for children of all ages and weight, whereas overall image quality decreases. CONCLUSION: SimGrid offers a differentiated spectrum in image improvement for children beyond the neonatal period whereas S-Enhance especially improves visibility of foreign material and bones for all patients.

RESUMO

BACKGROUND: Preventing healthcare-associated infections (HAI) in neonatal intensive care units is a challenge of highest priority. For further insight into the incubator as direct patient environment and potential source for contamination, we present data correlating microbiological samples of very low birthweight infants in the form of colonization results of surveillance screenings with samples of their associated incubator in this study. METHODS: Samples were taken via rectal and throat swabs of neonates as well as Polywipe® sponges for the incubator. If the same bacterial species was found in corresponding neonate and incubator samples, whole genome sequencing via Illumina technology was performed. RESULTS: 52 microbiological species matches were found, and 30 matches were sequenced where we found 26 clonal pairs (12 E. faecalis, 10 S. aureus, 2 E. coli, 1 E. cloacae, and 1 E. faecium). CONCLUSION: The combinations of measurements of weekly screenings swabs, probing of surfaces with Polywipes®, and whole genome sequencing showed transmissions of microorganism and risk for potential non-physiological colonization of neonatal infants.

RESUMO

OBJECTIVES: Worldwide, more than half of all sepsis cases occur in pediatric and adolescent patients, particularly in neonates. Previous population-based studies in these age groups often were limited to either neonatal or pediatric patients admitted to ICUs. We aimed to investigate the overall and age-specific incidence and case fatality of sepsis in children in Germany, a high-income country with a total population of 82 million. DESIGN: Retrospective observational study based on the German Diagnosis-related Groups statistics of the years 2010-2016. SETTING: All acute care hospitals in Germany except for prison and psychiatric hospitals. PATIENTS: Pediatric patients less than or equal to 19 years with International Classification of Diseases, 10th Revision-coded sepsis, neonates with International Classification of Diseases, 10th Revision-coded neonatal sepsis. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We analyzed pediatric sepsis incidence in patients aged birth to less than or equal to 19 years old, case fatality, and underlying comorbidities, and neonatal sepsis incidence and case fatality within the neonatal period. We identified 14,635 pediatric sepsis cases among 15.4 million pediatric hospitalizations between 2010 and 2016 (= 0.1% of pediatric hospitalizations). The incidence of pediatric sepsis was 14 cases per 100,000 children between 0 and 19 years. Case fatality was 16.6% and decreased from 17.8% (2010) to 15.0% (2016). A total of 11.5% of hospital deaths in the age group 0-19 years were associated with pediatric sepsis. Sepsis incidence and case fatality were highest in children less than 1 year old and declined in older children and adolescents. Admissions with pediatric sepsis were more common in children with preexisting comorbidities compared with those without (0.52% vs 0.03% of pediatric admissions). In neonates, the incidence of neonatal sepsis was 1,006 cases per 100,000 live births. Case fatality was 3.9%. While 17.7% of very low birth weight infants had neonatal sepsis, only 2.1% of low birth weight and 0.6% of normal birth weight neonates were affected, respectively. CONCLUSIONS: Sepsis is also in Germany a common and frequently fatal condition in pediatric patients, particularly among neonates and children with comorbidities.

RESUMO

OBJECTIVES: Due to a substantial proportion of asymptomatic and mild courses, many severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections remain unreported. Therefore, assessment of seroprevalence may detect the real burden of disease. We aimed to determine and characterize the rate of SARS-CoV-2 infections and the resulting seroprevalence in a defined population. The primary objective of the study was to assess SARS-CoV-2 antibody seroprevalence using six different IgG-detecting immunoassays. Secondary objectives of the study were: (a) to determine potential risk factors for symptomatic versus asymptomatic coronavirus disease 2019 courses, and (b) to investigate the rate of virus RNA-persistence. METHODS: CoNAN is a population-based cohort study performed in the community Neustadt am Rennsteig, Germany, which was quarantined from 22 March to 5 April after six SARS-CoV-2 cases were detected in the village's population. The SARS-CoV-2 outbreak comprised 51 cases and 3 deaths. The CoNAN study was performed from 13 May to 22 May 2020, 6 weeks after a SARS-CoV-2 outbreak. RESULTS: We enrolled a total of 626 participants (71% of the community population) for PCR and antibody testing in the study. All actual SARS-CoV-2 PCR tests were negative. Fifty-two out of 620 (8.4%) participants had antibodies against SARS-CoV-2 in at least two different assays. There were 38 participants with previously PCR-confirmed SARS-CoV-2 infection. Of those, only 19 (50%) displayed anti-SARS-CoV-2 antibodies. We also show that antibody-positive participants with symptoms compatible with a respiratory tract infection had significantly higher antibody levels then asymptomatic participants (EU-assay: median 2.9 versus 7.2 IgG-index, p 0.002; DS-assay: median 45.2 versus 143 AU/mL, p 0.002). Persisting viral replication was not detected. CONCLUSIONS: Our data question the relevance and reliability of IgG antibody testing to detect past SARS-CoV-2 infections 6 weeks after an outbreak. We conclude that assessing immunity for SARS-CoV-2 infection should not rely on antibody tests alone.

RESUMO

Objectives MR compatible incubators (MRcI) offer the examination of preterm and critically ill infants in controlled environment. The aim of the study was to compare objective and subjective image quality as well as diagnostic value of MRI brain examinations with and without using the MRcI. Thus, predictive value of brain MRI at expected delivery date in general was investigated. Methods This retrospective study included MRI brain examinations conducted at patients' corrected age ≤6 months and presence of four standard sequences (PD TSE transversal, T2 TSE transversal, T2 TSE sagittal and T1 SE transversal). Signal-to-Noise Ratio (SNR) and Contrast-to-Noise Ratio (CNR) was calculated. Subjective image quality was estimated using a 5-point Likert scale. Findings of MRI were compared with those of previous transfontanellar ultrasound because of additional diagnostic information. Severe brain abnormality scaled by score of Kidokoro was related to results of Munich Functional Developmental Diagnostics (MFDD) within first year. Results One hundred MRI brain examinations (76 with MRcI, 24 without MRcI) were performed in 79 patients. Using the MRcI SNR and CNR were significantly higher in PD- and in T2-weighted sequences (p<0.05). TSE PD transversal demonstrated a higher risk of non-diagnostic quality using MRcI (OR 5.23; 95%-CI 1.86-14.72). MRcI revealed additional diagnostic information (OR 5.69; 95%-CI 1.15-28.24). Severe brain abnormality was associated with walking deficits (r=0.570; p=0.021). Conclusions The MRcI increased objective image quality and revealed additional diagnostic information to transfontanellar ultrasound. Nevertheless, prediction of infants' future development remains limited.

RESUMO

Intrauterine growth restriction (IUGR) is present in fetuses that do not achieve their full in-utero growth potential. IUGR needs to be discriminated from small for gestational age (SGA) because IUGR newborns in particular experience long-term side effects from their small growth. IUGR fetuses have a significantly increased risk of prematurity and a distinct risk profile compared to adequate-for-gestational-age preterm newborns. Complications of prematurity are more frequent, including bronchopulmonary dysplasia, intraventricular hemorrhage, and meconium ileus. IUGR newborns are at risk of long-term health issues like cerebral palsy, impaired lung function, and delayed speech development. Interdisciplinary and interprofessional care of IUGR pregnancies in the context of a standardized health care research project is feasible: Pregnant women at risk are identified, early therapy with acetylsalicylic acid is started as indicated, risk-adapted care at level III centers is organized including psychosocial interventions and neonatal consultations. Postnatally, integrated neonatal care focusing on parent-child interaction and optimized nutrition is a hallmark. Afterwards, in-depth pediatric follow-up visits with local pediatricians help to identify growth and neurodevelopment problems early. The effects, acceptance. and cost efficiency of this approach are evaluated prospectively as part of an Innovationsfonds project.

RESUMO

PURPOSE: The aim was to determine whether the quantitative ultrasound (QUS) parameter speed of sound (SOS) is sufficient for evaluation of reference data in the newborn and how they are influenced. MATERIALS AND METHODS: 219 full-term and 14 preterm infants (gestational age 28-41 weeks (GA), birth weight 590-4,930 g) were evaluated by Omnisense 7000 P on their tibia. Reference values were sampled in 178 eutrophic infants. RESULTS: SOS reference values at the tibia were 3028 m/s for GA<40 and 3057 m/s for ≥ 40 weeks. There was a significant correlation between SOS and gestational age. SOS was significantly higher in male (3058.3±93.3 vs. 3022.8±93.4 m/s; p 0.012) infants. If birth weight was below 3,800 g, there was a correlation between SOS and weight (p<0.05). Preterm infants showed lower SOS than term babies (p<0.05). CONCLUSION: Speed of sound can be evaluated sufficiently in preterm and term infants on the tibia. The estimated reference data can be used to identify osteopenia in the preterm infant with low birth weight.

RESUMO

BACKGROUND: The diagnostic proof of fungal infection in preterm infants is difficult. Antifungal treatment (AFT) is often initiated empirically when infants with suspected infection do not improve despite broad-spectrum antibiotic therapy. It was the aim of our study to determine the rate of exposure to empirical AFT in a large cohort of very low birth weight infants (VLBWI) of the German Neonatal Network and to address associated risks and outcomes. METHODS: The epidemiologic database consisted of n = 13,343 VLBWI born in 54 German Neonatal Network centers between 2009 and 2015. AFT was defined as number of neonates who got any dose of at least one of the following antifungal drugs: fluconazole, amphotericin B, voriconazole and caspofungin (denominator: number of infants enrolled in German Neonatal Network) for treatment (not prophylaxis) of (suspected) fungal infection. Univariate and logistic regression analyses were used to identify risk factors for exposure to AFT and associated short-term morbidities and long-term outcomes at 5-year follow-up. RESULTS: In our cohort, 724 out of 13,343 (5.4%) VLBWI were exposed to empiric AFT and had a mean gestational age of 25.7 (±2.1) weeks. Forty-four out of 13,343 (0.3%) had proven bloodstream infection with Candida spp. The main risk factors for exposure to AFT were gestational age, postnatal steroid treatment, need for abdominal surgery and use of carbapenems. Notably, AFT was associated with adverse outcomes such as bronchopulmonary dysplasia [adjusted odds ratio (OR): 1.9; 95% confidence interval (CI): 1.6-2.3; P < 0.001) and retinopathy of prematurity requiring intervention (adjusted OR: 1.69; 95% CI: 1.3-2.3; P <0.001) but not mortality. In the subgroup of infants available for 5-year follow-up (n = 895), exposure to AFT was associated with a risk for cerebral palsy (adjusted OR: 2.79; 95% CI: 1.11-7.04; P = 0.04) and intelligence quotient < 85 (adjusted OR: 2.07; 95% CI: 1.01-4.28; P = 0.049). CONCLUSIONS: A significant proportion of VLBWI is exposed to AFT, specifically those born <26 weeks. Exposed infants were found to have a higher risk for adverse outcomes, which may reflect their significant vulnerability in general. Given the observational design of our study, it remains unclear whether potential side effects of empirical or target AFT itself contribute to adverse outcome. Future studies need to include risk-based strategies and stewardship programs to restrict the use of antifungal management in VLBWI.

RESUMO

Pontine tegmental cap dysplasia is a rare hindbrain malformation syndrome with a hypoplastic pons, a tissue protrusion into the fourth ventricle, and cranial nerve dysfunction. We here report clinical, imaging, and genetic findings of the first extremely low-birth-weight preterm infant with pontine tegmental cap dysplasia born at 25 weeks of gestation and provide an overview of 29 sporadic cases. A prenatally diagnosed hypoplastic and rostrally shifted cerebellum was indicative of a hindbrain defect and later identified as an early sign of pontine tegmental cap dysplasia in our patient. The neonate exhibited severe muscle hypotonia, persistent thermolability, and clinical signs of an involvement of facial, cochlear, and hypoglossal nerves. Furthermore, paroxysmal episodes of agonizing pain with facial tics, tonic and clonic muscle contractions, blepharospasm, and singultus are highlighted as new phenotypic features of pontine tegmental cap dysplasia. With our report, we present a severe case of pontine tegmental cap dysplasia and provide a brief overview of current knowledge on this rare disease.

RESUMO

Systematic recording of practical implementation of current recommendations of KRINKO for the prevention of nosocomial infections in premature and newborn infants in children's hospitals in Thuringia. All neonatal treatment centers in Thuringia (n=18) were included in this survey. Answer were received from 83% (15/18). Degree of compliance was 100% in level-1 (3/3) and level-2 centers (5/5), and 70% in level-3 centers (7/10). The aim of the questionnaire was to evaluate infection prevention measures as well as structural/organizational parameters in neonatal centers in Thuringia. Preventive measures as well as weekly screening for colonization was fully performed in patients with a birth weight <1 500 g (n=205) at all centers. Additionally, prolonged screening and colonization surveillance measures were performed in 60% of all units until discharge from the hospital. Results related to structural/organizational parameters and especially structural conditions in neonatal centers in Thuringia pointed up challenges (2 m minimum distance between incubators in 27% (n=4/15), isolation in single room in 53% (n=8/15)). Insufficient number of staff also hamper the complete implementation of KRINKO recommendations (intensive care unit: patient/staff ratio (MW±SD) 2.5±1.1; newborn area 4.3±0.9). Analysis shows actual rate of implementation of KRINKO recommendations as well as structural/organizational parameters in neonatal treatment centers in Thuringia. It provides important points for discussion regarding necessary staff numbers and structural conditions. Analysis could also be used for future surveys in other regions in Germany.
