Abstract
PURPOSE In contrast to adults, immune protection against SARS-CoV-2 in children and adolescents with natural or hybrid immunity is still poorly understood. The aim of this study was to analyze different immune compartments in different age groups and whether humoral immune reactions correlate with a cellular immune response. METHODS 72 children and adolescents with a preceding SARS-CoV-2 infection were recruited. 37 were vaccinated with an RNA vaccine (BNT162b2). Humoral immunity was analyzed 3-26 months (median 10 months) after infection by measuring Spike protein (S), nucleocapsid (NCP), and neutralizing antibodies (nAB). Cellular immunity was analyzed using a SARS-CoV-2-specific interferon-γ release assay (IGRA). RESULTS All children and adolescents had S antibodies; titers were higher in those with hybrid immunity (14,900 BAU/ml vs. 2118 BAU/ml). NCP antibodies were detectable in > 90%. Neutralizing antibodies (nAB) were more frequently detected (90%) with higher titers (1914 RLU) in adolescents with hybrid immunity than in children with natural immunity (62.5%, 476 RLU). Children with natural immunity were less likely to have reactive IGRAs (43.8%) than adolescents with hybrid immunity (85%). The amount of interferon-γ released by T cells was comparable in natural and hybrid immunity. CONCLUSION Spike antibodies are the most reliable markers to monitor an immune reaction against SARS-CoV-2. High antibody titers of spike antibodies and nAB correlated with cellular immunity, a phenomenon found only in adolescents with hybrid immunity. Hybrid immunity is associated with markedly higher antibody titers and a higher probability of a cellular immune response than a natural immunity.

Abstract
PURPOSE Hyposmia in childhood is poorly characterized. The "U-Sniff Test", validated for children with anosmia, can be used to objectify olfactory impairment but has not been used to distinguish between hyposmia and normosmia. Therefore, we investigated children with enlarged adenoids with respect to hyposmia, its correlation with adenoid size, and the sensitivity of questionnaires to predict olfactory impairment. METHODS In a prospective comparison, olfaction was assessed by "U-Sniff Test" (score 0-12; <8 hyposmia) in 41 children (5-18 years) with adenoid hyperplasia and compared with 196 children without any respiratory affection (control) after exclusion of previous SARS-Cov2-infection from December 2020 to December 2021. ENT-related complaints were collected using a self-designed questionnaire. We were able to include 13 children in a follow-up examination to compare preoperative performance in the "U-Sniff Test" with postoperative outcome after adenoidectomy. STATISTICS chi-square-test (p < 0.05), odds-ratio, Spearman's rho, ROC-, cluster analysis. RESULTS Severe hyposmia was present in 36.6% of children with adenoid-hyperplasia compared to 3.1% of the control-group. Adenoid-children scored significantly more often between 8 and 10 points (58.5%) than the control (31.6%; p < 0.01). Adenoid size and olfactory performance correlate significantly (r: 0.83; CI -0.89 … -0.72). Hyposmia in the adenoid group is characterized predominately by loss of the odors banana, butter and rose. None of children with hyposmia or parents reported impaired olfactory performance. Postoperatively, olfactory function improved significantly in 85% of cases (p 0.01, SD ± 1.71, Δ3.54points). CONCLUSION Questionnaires are insufficient to detect hyposmia in this cohort. In contrast, the "U-Sniff Test" detects even reduced olfactory performance without reaching the cut-off value, which represents the majority of test results in the adenoid group. Therefore, we recommend the classification of moderate hyposmia (8-10 points) to be included for our study population.

Abstract
Exhaled breath contains numerous volatile organic compounds (VOCs) known to be related to lung disease like asthma. Its collection is non-invasive, simple to perform and therefore an attractive method for the use even in young children. We analysed breath in children of the multicenter All Age Asthma Cohort (ALLIANCE) to evaluate if 'breathomics' have the potential to phenotype patients with asthma and wheeze, and to identify extrinsic risk factors for underlying disease mechanisms. A breath sample was collected from 142 children (asthma: 51, pre-school wheezers: 55, healthy controls: 36) and analysed using gas chromatography-mass spectrometry (GC/MS). Children were diagnosed according to Global Initiative for Asthma guidelines and comprehensively examined each year over up to seven years. Forty children repeated the breath collection after 24 or 48 months. Most breath VOCs differing between groups reflect the exposome of the children. We observed lower levels of lifestyle-related VOCs and higher levels of the environmental pollutants, especially naphthalene, in children with asthma or wheeze. Naphthalene was also higher in symptomatic patients and in wheezers with recent inhaled corticosteroid use. No relationships with lung function or TH2 inflammation were detected. Increased levels of naphthalene in asthmatics and wheezers and the relationship to disease severity could indicate a role of environmental or indoor air pollution for the development or progress of asthma. Breath VOCs might help to elucidate the role of the exposome for the development of asthma. The study was registered at ClinicalTrials.gov (NCT02496468).

Abstract
BACKGROUND Cystic fibrosis (CF) is a rare genetic multisystemic disorder with progressive abdominal and pulmonary involvement. Pain is still an underestimated symptom in CF patients. METHODS A comprehensive review of guidelines and scientific literature on the topic was performed and combined with findings from pain management in a young CF patient with progressive thoracic pain. RESULTS German CF guidelines do not cover diagnosis and management of pain in these patients. Studies from Europe and the United States report interactions between intensity of pain and mortality in CF, but do not include data on the efficacy of pain management. These data and clinical observations of a CF patient with episodes of intense thoracic pain are used to illustrate the specific challenges in pain relief. CONCLUSION Pain management in CF requires meticulous monitoring as well as an interdisciplinary approach and should be implemented in the German CF guidelines. The authors also want to suggest recommendations for the treatment of thoracic pain in CF. The range and severity of organ involvement complicates the use both of opioids and non-opioids. Especially opioid treatment carries the risk of hypoxia and opioid-induced constipation (OIC) and needs close medical supervision.

Abstract
Intestinal epithelial cells absorb nutrients through the brush border, composed of dense arrays of highly ordered microvilli at their apical membranes. A protocadherin-based intermicrovillar adhesion complex localized at microvilli tips mediates microvilli packing and organization. Here, we identified a second adhesion complex localized at the proximal base region of microvilli. This complex contained the immunoglobulin superfamily member TMIGD1, which directly interacted with the microvillar scaffolding proteins EBP50 and E3KARP. Complex formation with EBP50 required the activation of EBP50 by the actin-binding protein ezrin and was enhanced by the dephosphorylation of Ser162 in the PDZ2 domain of EBP50 by the phosphatase PP1α. Binding of the EBP50-ezrin complex to TMIGD1 enhanced the dynamic turnover of EBP50 at microvilli. Enterocyte-specific inactivation of Tmigd1 in mice resulted in microvillar blebbing, loss of intermicrovillar adhesion, and perturbed brush border formation. Thus, we identified a second adhesion complex in microvilli and propose a mechanism that promotes microvillar formation and dynamics.

Abstract
Contact inhibition of locomotion (CIL) is a process that regulates cell motility upon collision with other cells. Improper regulation of CIL has been implicated in cancer cell dissemination. Here, we identify the cell adhesion molecule JAM-A as a central regulator of CIL in tumor cells. JAM-A is part of a multimolecular signaling complex in which tetraspanins CD9 and CD81 link JAM-A to αvβ5 integrin. JAM-A binds Csk and inhibits the activity of αvβ5 integrin-associated Src. Loss of JAM-A results in increased activities of downstream effectors of Src, including Erk1/2, Abi1, and paxillin, as well as increased activity of Rac1 at cell-cell contact sites. As a consequence, JAM-A-depleted cells show increased motility, have a higher cell-matrix turnover, and fail to halt migration when colliding with other cells. We also find that proper regulation of CIL depends on αvβ5 integrin engagement. Our findings identify a molecular mechanism that regulates CIL in tumor cells and have implications on tumor cell dissemination.

Abstract
Die Primäre Ciliäre Dyskinesie (PCD, MIM 242650) ist eine seltene hereditäre Multisystemerkrankung mit klinisch heterogenem Phänotyp. Leitsymptom ist eine chronische Sekretretention der oberen und unteren Atemwege, welche durch die Dysfunktion motiler respiratorischer Zilien entsteht. In der Folge kommt es zur Ausbildung von Bronchiektasen, häufig zu einer Infektion durch Pseudomonas aeruginosa sowie einer abnehmenden Lungenfunktion bis hin zum Lungenversagen. Bislang gibt es kaum evidenzbasierte Therapieempfehlungen, da randomisierte Langzeitstudien zur Behandlung der PCD fehlten. In diesem Jahr wurden die Daten einer ersten placebokontrollierten Medikamentenstudie bei PCD veröffentlicht. Anlässlich dieses Meilensteins im Management der PCD wurde der vorliegende Übersichtsartikel als Konsens von Patientenvertretern sowie Klinikern, die langjährige Erfahrung in der Behandlung der PCD haben, verfasst. Diese Arbeit bietet eine Zusammenfassung aktuell eingesetzter Behandlungsverfahren, die überwiegend auf persönlichen Erfahrungen und Expertenmeinungen beruhen oder von anderen Atemwegserkrankungen wie der Cystischen Fibrose (CF), COPD oder Bronchiektasen-Erkrankung abgeleitet werden. Da es derzeit keine kurative Therapie für PCD gibt, stehen symptomatische Maßnahmen wie die regelmäßige Reinigung der Atemwege und die Behandlung von rezidivierenden Atemwegsinfektionen im Fokus. Nicht respiratorische Manifestationen werden organspezifisch behandelt. Um neben der ersten Medikamentenstudie mehr evidenzbasiertes Wissen zu generieren, werden weitere Projekte etabliert, u. a. ein internationales PCD-Register. Hierüber wird Patienten der Zugang zu klinischen und wissenschaftlichen Studien erleichtert und die Vernetzung behandelnder Zentren gefördert. Des Weiteren können Erkenntnisse über eine Genotyp-spezifische Erkrankungsschwere erlangt werden, um folglich die therapeutische Versorgung der Patienten zu verbessern und somit zu individualisieren.

Abstract
The present guideline aims to improve the evidence-based management of children and adolescents with pediatric community-acquired pneumonia (pCAP). Despite a prevalence of approx. 300 cases per 100 000 children per year in Central Europe, mortality is very low. Prevention includes infection control measures and comprehensive immunization. The diagnosis can and should be established clinically by history, physical examination and pulse oximetry, with fever and tachypnea as cardinal features. Additional signs or symptoms such as severely compromised general condition, poor feeding, dehydration, altered consciousness or seizures discriminate subjects with severe pCAP from those with non-severe pCAP. Within an age-dependent spectrum of infectious agents, bacterial etiology cannot be reliably differentiated from viral or mixed infections by currently available biomarkers. Most children and adolescents with non-severe pCAP and oxygen saturation > 92 % can be managed as outpatients without laboratory/microbiology workup or imaging. Anti-infective agents are not generally indicated and can be safely withheld especially in children of young age, with wheeze or other indices suggesting a viral origin. For calculated antibiotic therapy, aminopenicillins are the preferred drug class with comparable efficacy of oral (amoxicillin) and intravenous administration (ampicillin). Follow-up evaluation after 48 - 72 hours is mandatory for the assessment of clinical course, treatment success and potential complications such as parapneumonic pleural effusion or empyema, which may necessitate alternative or add-on therapy.

Abstract
BACKGROUND Transmembrane and immunoglobulin domain-containing protein 1 (TMIGD1) is a recently identified cell adhesion molecule which is predominantly expressed by epithelial cells of the intestine and the kidney. Its expression is downregulated in both colon and renal cancer suggesting a tumor suppressive activity. The function of TMIGD1 at the cellular level is largely unclear. Published work suggests a protective role of TMIGD1 during oxidative stress in kidney epithelial cells, but the underlying molecular mechanisms are unknown. RESULTS In this study, we address the subcellular localization of TMIGD1 in renal epithelial cells and identify a cytoplasmic scaffold protein as interaction partner of TMIGD1. We find that TMIGD1 localizes to different compartments in renal epithelial cells and that this localization is regulated by cell confluency. Whereas it localizes to mitochondria in subconfluent cells it is localized at cell-cell contacts in confluent cells. We find that cell-cell contact localization is regulated by N-glycosylation and that both the extracellular and the cytoplasmic domain contribute to this localization. We identify Synaptojanin 2-binding protein (SYNJ2BP), a PDZ domain-containing cytoplasmic protein, which localizes to both mitochondria and the plasma membrane, as interaction partner of TMIGD1. The interaction of TMIGD1 and SYNJ2BP is mediated by the PDZ domain of SYNJ2BP and the C-terminal PDZ domain-binding motif of TMIGD1. We also find that SYNJ2BP can actively recruit TMIGD1 to mitochondria providing a potential mechanism for the localization of TMIGD1 at mitochondria. CONCLUSIONS This study describes TMIGD1 as an adhesion receptor that can localize to both mitochondria and cell-cell junctions in renal epithelial cells. It identifies SYNJ2BP as an interaction partner of TMIGD1 providing a potential mechanism underlying the localization of TMIGD1 at mitochondria. The study thus lays the basis for a better understanding of the molecular function of TMIGD1 during oxidative stress regulation.

Abstract
SETTING In June 2014, we became aware that shortages of purified protein derivative (PPD), the test substance used for the tuberculin skin test (TST), had occurred in several European health care institutions providing care for children with tuberculosis (TB). OBJECTIVE To establish the extent of the shortage, a survey was performed. DESIGN Survey conducted over a 1-month period (June-July 2014) among members of the Paediatric Tuberculosis Network European Trials Group (ptbnet). RESULTS Thirty-five physicians from 23 European countries contributed data. The most commonly used PPD product was RT23 (Statens Serum Institut; n = 22, 63%). Twenty-one (60%) participants reported that their institution was experiencing a PPD shortage. The majority (n = 17, 81%) of those reporting a shortage were using RT23. Thirteen (37%) participants reported changes in screening practices resulting from the shortage, including sourcing PPD from alternative manufacturers, restricting remaining supplies to patients at greatest risk or replacing TST by an interferon-gamma release assay. CONCLUSIONS The data show that a PPD shortage occurred in 2014, affecting multiple European countries. The shortage resulted in changes in TB screening capabilities and practices, potentially compromising both patient care as well as public health efforts. Appropriate actions to prevent future PPD shortages should be explored urgently by public health agencies and key stakeholders.

Abstract
The World Health Organization European Region has one of the highest rates of multidrug-resistant tuberculosis (MDR-TB) in the world, resulting in many vulnerable children being exposed each year. Evidence for preventive therapy following MDR-TB exposure is limited and current guidance is conflicting. An internet-based survey was performed to determine clinical practice in this region. Seventy-two clinicians from 25 countries participated. Practices related to screening and decision-making were highly variable. Just over half provided preventive therapy for children exposed to MDR-TB; the only characteristic associated with provision was practice within the European Union (adjusted OR 4.07, 95%CI 1.33-12.5).

Abstract
BACKGROUND Abnormal transcranial Doppler velocities (TCD) indicate an increased risk of stroke in patients with sickle cell anemia (SCA) and require regular blood transfusions. Hematopoietic stem cell transplantation (HSCT) is under discussion as an alternative to chronic transfusion in these patients. PATIENTS AND METHODS This retrospective analysis includes 9 patients with SCA undergoing HSCT at a single center in Germany. Special focus was given to the neurologic follow-up and to the results of TCD studies. RESULTS High risk of stroke or previous stroke was an HSCT-indication in 8 of 9 patients, although most patients had more than one indication for HSCT. TCD was normalized in all 5 patients after HSCT in whom this test was available. None of the patients developed a stroke after HSCT. No further strokes occurred even in patients that experienced recurrent strokes during chronic transfusion before HSCT. 2 of the 9 patients received a 10/10 HLA-matched unrelated donor graft, the others matched related grafts.All patients were alive, free of SCA symptoms and transfusion-independent with stable chimerism 3-11 years after HSCT. Pulmonary function tests normalized in 1 patient with severe sickle cell lung disease. CONCLUSION HSCT is able to prevent stroke in patients with SCA. Its perspectives and limitations should be discussed early during the treatment of a patient with complicated SCA.

Abstract
BACKGROUND AND OBJECTIVE In a prospective, non-randomised, multicentre cohort study we compared intensive surveillance to symptom-oriented control in the follow-up of patients with early breast cancer after curative surgical treatment. Five-year overall survival had shown that symptom-oriented follow-up was not inferior to intensive control. However, a more intensive, instrumental based follow-up is still claimed by many patients and their physicians. In this context the recent data of 10-year overall survival (OS) are reported. PATIENTS AND METHODS In the prospective, non-randomised, multicentre cohort study carried out between 1995 and 2000, 244 patients underwent an intensive follow-up (scheduled laboratory tests including CEA and CA 15-3, chest X-rays and liver ultrasound). 426 patients were monitored in a symptom-oriented manner (additional tests only in the case of symptoms indicating possible recurrence). Mammography, structured histories and physical examinations were done regularly in both groups. RESULTS In the clinical follow-up group, 90 deaths (21.2 %) were observed with an estimated 10-year overall survival rate of 83.0 % (95 % CI 79.1 -86.3 %). In the intensive follow-up group, 59 deaths (24.2 %) were observed with an estimated 10-year overall survival rate of 78.5 % (95 % CI 72.6 -83.2 %). The Cox proportional hazards model for OS includes the variables follow-up form, stage of primary tumor and lymph nodes, hormone receptor status, grading and age at diagnosis. This model resulted in a hazard ratio of 1.10 (95 % CI 0.78-1.54) for the follow-up protocol (intensive vs. clinical). Welleks' test for non-inferiority showed that clinical follow-up is not inferior in comparison to intensive follow-up (p < 0.05) for a non-inferiority limit of + 7 % at 10-years. CONCLUSION This analysis of 10-year overall survival of patients with early breast cancer after curative primary treatment confirms that follow-up without regular imaging and laboratory tests is not inferior in the sense of a relevant higher mortality. To what extent new concepts in the treatment of breast cancer have any influence on follow-up care has to be examined in further studies.

Abstract
BACKGROUND Treatment decisions in breast cancer depend on TNM classification and the assessment of additional variables with have an impact on survival. We examined whether histological subtyping breast cancer as either ductal or lobular is related to disease outcome. PATIENTS AND METHODS We examined a large data base of 14198 breast cancer patients. RESULTS Histological sub-classification of invasive breast cancer as either ductal or lobular is not correlated with disease outcome. However, the data further showed that invasive lobular carcinomas have a higher probability of being oestrogen receptor (ER)- and progesterone receptor (PR)-positive and a lower probability of being c-erbB2-positive. They also showed a higher average age at the time of diagnosis in comparison with invasive ductal carcinoma. Local recurrence rates were lower in invasive lobular carcinoma in comparison with invasive ductal carcinoma (3.5% vs. 6.2%; p = 0.031). The multivariable Cox regression analysis showed that ER, PR, nodal status, grade and tumour size predicted disease outcome with statistical significance, while the histological subtype (invasive ductal or lobular) was not a significant predictor of disease outcome. CONCLUSION Histological sub-classification of invasive breast cancer as either ductal or lobular is not correlated with disease outcome. On the other hand our data gives some indication that lobular and ductal breast cancer appear to be different biological entities.

Abstract
Tracheal intubation with the intubating laryngeal mask airway or the Bonfils intubation fibrescope was performed in 80 patients with predicted difficult airways. Mallampati score, thyromental distance, mouth opening and mobility of the atlanto-occipital joint were used to predict difficult airways. The overall success rate, time to the first adequate lung ventilation and time taken for the successful placement of the tracheal tube were recorded, as well as a subjective assessment of the handling of the device and the incidence of postoperative sore throat and hoarseness. The median [range] time to the first adequate ventilation was significantly shorter with the intubating laryngeal mask airway than with the Bonfils intubation fibrescope (28 [6-85] s vs. 40 [23-77] s, p < 0.005). Tracheal intubation was significantly slower with the intubating laryngeal mask airway than with the Bonfils intubation fibrescope (76 [45-155] s vs. 40 [23-77] s, p < 0.0001. Patients in the Bonfils group suffered less sore throat and hoarseness than those in the other group.

Abstract
We report on a market research study on the acceptance of computer systems in surgeries. 11,000 returned questionnaires of surgeons--user and nonuser--were analysed. We found out that most of the surgeons used their computers in a limited way, i.e. as a device for accounting. Concerning the level of utilisation there are differentials of Men-Women, West-East and Young-Old. In this study we also analysed the computer using behaviour of gynaecologic surgeons. As a result two third of all nonusers are not intending to utilise a computer in the future.

Abstract
A distributed-feedback (DFB) dye laser that is pumped by a standing Bessel-beam wave is constructed. Because of the long line focus of the Bessel beam, the laser medium is pumped in only a very thin filament (a few micrometers) along the optical axis. At the same time, longitudinal-mode selection is achieved because of the DFB effect. It is demonstrated that when the effective wavelength of the Bessel pump beam is varied, the Bragg wavelength for DFB is altered, and as a result the output wavelength can be tuned.

Abstract
In our study we compared five methods of testing the sensitivity of yeasts against 5 Fluorocytosine. We examined these five methods with regard to their ability for the laboratory routine. We found, in accordance with other authors, the microtiter technique to be the most useful one. In the second part of our study we were able to show, that it is possible to induce in yeasts a secondary resistance to 5 FC in vitro.
