On the other hand, immune thrombocytopenia (ITP) represents an acquired and often self-limiting benign hematologic disorder, associated with peripheral, immune-mediated, platelet destruction requiring different management modalities than those used in congenital bone marrow failure syndromes, including FA. Here, we describe the clinical course of two independent FA patients with atypical - namely immune - thrombocytopenia. While in one patient belonging to complementation group FA-A, the ITP started at 17 months of age and showed a chronically persisting course with severe purpura, responding well to intravenous immunoglobulins (IVIG) and later also danazol, a synthetic androgen, the other patient (of complementation group FA-D2) had a self-limiting course that resolved after one administration of IVIG. No cytogenetic aberrations or bone marrow abnormalities other than FA-typical mild dysplasia were detected. Our data show that acute and chronic ITP may occur in FA patients and impose individual diagnostic and therapeutic challenges in this rare congenital bone marrow failure/tumor predisposition syndrome. The management and a potential context of immune pathogenesis with the underlying marrow disorder are discussed.}, language = {en} } @article{HornickRichterHarpoleetal.2022, author = {Hornick, Thomas and Richter, Anett and Harpole, William Stanley and Bastl, Maximilian and Bohlmann, Stephanie and Bonn, Aletta and Bumberger, Jan and Dietrich, Peter and Gemeinholzer, Birgit and Grote, R{\"u}diger and Heinold, Bernd and Keller, Alexander and Luttkus, Marie L. and M{\"a}der, Patrick and Motivans Švara, Elena and Passonneau, Sarah and Punyasena, Surangi W. and Rakosy, Demetra and Richter, Ronny and Sickel, Wiebke and Steffan-Dewenter, Ingolf and Theodorou, Panagiotis and Treudler, Regina and Werchan, Barbora and Werchan, Matthias and Wolke, Ralf and Dunker, Susanne}, title = {An integrative environmental pollen diversity assessment and its importance for the Sustainable Development Goals}, series = {Plants, People, Planet}, volume = {4}, journal = {Plants, People, Planet}, number = {2}, doi = {10.1002/ppp3.10234}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-276487}, pages = {110 -- 121}, year = {2022}, abstract = {Societal Impact Statement Pollen relates to many aspects of human and environmental health, which protection and improvement are endorsed by the United Nations Sustainable Development Goals. By highlighting these connections in the frame of current challenges in monitoring and research, we discuss the need of more integrative and multidisciplinary pollen research related to societal needs, improving health of humans and our ecosystems for a sustainable future. Summary Pollen is at once intimately part of the reproductive cycle of seed plants and simultaneously highly relevant for the environment (pollinators, vector for nutrients, or organisms), people (food safety and health), and climate (cloud condensation nuclei and climate reconstruction). We provide an interdisciplinary perspective on the many and connected roles of pollen to foster a better integration of the currently disparate fields of pollen research, which would benefit from the sharing of general knowledge, technical advancements, or data processing solutions. We propose a more interdisciplinary and holistic research approach that encompasses total environmental pollen diversity (ePD) (wind and animal and occasionally water distributed pollen) at multiple levels of diversity (genotypic, phenotypic, physiological, chemical, and functional) across space and time. This interdisciplinary approach holds the potential to contribute to pressing human issues, including addressing United Nations Sustainable Development Goals, fostering social and political awareness of these tiny yet important and fascinating particles.}, language = {en} } @article{KaemmererTribiusCohrsetal.2023, author = {K{\"a}mmerer, Peer W. and Tribius, Silke and Cohrs, Lena and Engler, Gabriel and Ettl, Tobias and Freier, Kolja and Frerich, Bernhard and Ghanaati, Shahram and Gosau, Martin and Haim, Dominik and Hartmann, Stefan and Heiland, Max and Herbst, Manuel and Hoefert, Sebastian and Hoffmann, J{\"u}rgen and H{\"o}lzle, Frank and Howaldt, Hans-Peter and Kreutzer, Kilian and Leonhardt, Henry and Lutz, Rainer and Moergel, Maximilian and Modabber, Ali and Neff, Andreas and Pietzka, Sebastian and Rau, Andrea and Reichert, Torsten E. and Smeets, Ralf and Sproll, Christoph and Steller, Daniel and Wiltfang, J{\"o}rg and Wolff, Klaus-Dietrich and Kronfeld, Kai and Al-Nawas, Bilal}, title = {Adjuvant radiotherapy in patients with squamous cell carcinoma of the oral cavity or oropharynx and solitary ipsilateral lymph node metastasis (pN1) — a prospective multicentric cohort study}, series = {Cancers}, volume = {15}, journal = {Cancers}, number = {6}, issn = {2072-6694}, doi = {10.3390/cancers15061833}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-311024}, year = {2023}, abstract = {(1) Background: Evaluation of impact of adjuvant radiation therapy (RT) in patients with oral squamous cell carcinoma of the oral cavity/oropharynx (OSCC) of up to 4 cm (pT1/pT2) and solitary ipsilateral lymph node metastasis (pN1). A non-irradiated group with clinical follow-up was chosen for control, and survival and quality of life (QL) were compared; (2) Methods: This prospective multicentric comprehensive cohort study included patients with resected OSCC (pT1/pT2, pN1, and cM0) who were allocated into adjuvant radiation therapy (RT) or observation. The primary endpoint was overall survival. Secondary endpoints were progression-free survival and QL after surgery; (3) Results: Out of 27 centers, 209 patients were enrolled with a median follow-up of 3.4 years. An amount of 137 patients were in the observation arm, and 72 received adjuvant irradiation. Overall survival did not differ between groups (hazard ratio (HR) 0.98 [0.55-1.73], p = 0.94). There were fewer neck metastases (HR 0.34 [0.15-0.77]; p = 0.01), as well as fewer local recurrences (HR 0.41 [0.19-0.89]; p = 0.02) under adjuvant RT. For QL, irradiated patients showed higher values for the symptom scale pain after 0.5, two, and three years (all p < 0.05). After six months and three years, irradiated patients reported higher symptom burdens (impaired swallowing, speech, as well as teeth-related problems (all p < 0.05)). Patients in the RT group had significantly more problems with mouth opening after six months, one, and two years (p < 0.05); (4) Conclusions: Adjuvant RT in patients with early SCC of the oral cavity and oropharynx does not seem to influence overall survival, but it positively affects progression-free survival. However, irradiated patients report a significantly decreased QL up to three years after therapy compared to the observation group.}, language = {en} } @article{HechtMeierZimmeretal.2018, author = {Hecht, Markus and Meier, Friedegund and Zimmer, Lisa and Polat, B{\"u}lent and Loquai, Carmen and Weishaupt, Carsten and Forschner, Andrea and Gutzmer, Ralf and Utikal, Jochen S. and Goldinger, Simone M. and Geier, Michael and Hassel, Jessica C. and Balermpas, Panagiotis and Kiecker, Felix and Rauschenberg, Ricarda and Dietrich, Ursula and Clemens, Patrick and Berking, Carola and Grabenbauer, Gerhard and Schadendorf, Dirk and Grabbe, Stephan and Schuler, Gerold and Fietkau, Rainer and Distel, Luitpold V. and Heinzerling, Lucie}, title = {Clinical outcome of concomitant vs interrupted BRAF inhibitor therapy during radiotherapy in melanoma patients}, series = {British Journal of Cancer}, volume = {118}, journal = {British Journal of Cancer}, doi = {10.1038/bjc.2017.489}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-227970}, pages = {785-792}, year = {2018}, abstract = {Background: Concomitant radiation with BRAF inhibitor (BRAFi) therapy may increase radiation-induced side effects but also potentially improve tumour control in melanoma patients. Methods: A total of 155 patients with BRAF-mutated melanoma from 17 European skin cancer centres were retrospectively analysed. Out of these, 87 patients received concomitant radiotherapy and BRAFi (59 vemurafenib, 28 dabrafenib), while in 68 patients BRAFi therapy was interrupted during radiation (51 vemurafenib, 17 dabrafenib). Overall survival was calculated from the first radiation (OSRT) and from start of BRAFi therapy (OSBRAFi). Results: The median duration of BRAFi treatment interruption prior to radiotherapy was 4 days and lasted for 17 days. Median OSRT and OSBRAFi in the entire cohort were 9.8 and 12.6 months in the interrupted group and 7.3 and 11.5 months in the concomitant group (P=0.075/P=0.217), respectively. Interrupted vemurafenib treatment with a median OSRT and OSBRAFi of 10.1 and 13.1 months, respectively, was superior to concomitant vemurafenib treatment with a median OSRT and OSBRAFi of 6.6 and 10.9 months (P=0.004/P=0.067). Interrupted dabrafenib treatment with a median OSRT and OSBRAFi of 7.7 and 9.8 months, respectively, did not differ from concomitant dabrafenib treatment with a median OSRT and OSBRAFi of 9.9 and 11.6 months (P=0.132/P=0.404). Median local control of the irradiated area did not differ in the interrupted and concomitant BRAFi treatment groups (P=0.619). Skin toxicity of grade ≥2 (CTCAE) was significantly increased in patients with concomitant vemurafenib compared to the group with treatment interruption (P=0.002). Conclusions: Interruption of vemurafenib treatment during radiation was associated with better survival and less toxicity compared to concomitant treatment. Due to lower number of patients, the relevance of treatment interruption in dabrafenib treated patients should be further investigated. The results of this analysis indicate that treatment with the BRAFi vemurafenib should be interrupted during radiotherapy.

In this paper, we present our novel approach to surgical extrusion and subsequent management of teeth using a vertical extraction system (Benex), which has become the method of choice in the authors' practice for many teeth that would otherwise be deemed unrestorable. We describe the clinical procedure in detail and discuss the advantages and disadvantages compared to alternative approaches, including surgical crown lengthening and orthodontic extrusion.}, language = {en} }
