Abstract
BACKGROUND Although rare, allergic reactions to metal implants represent a diagnostic challenge in view of missing guidelines. OBJECTIVES To develop an European expert consensus on characteristics of metal allergy reactions and the utility of various diagnostic tools in suspected metal implant allergy. METHODS A nominal group technique (NGT) was applied to develop consensus statements. Initially an online literature database was created on a secure server to enable a comprehensive information. Twenty-three statements were formulated on potential aspects of metal implant allergy with a focus on diagnostics and grouped into five domains. For the consensus development, the panel of 12 experts initially did refine and reformulate those statements that were ambiguous or had unclear wording. By face-to-face (9/12) or virtual participation (3/12), an anonymous online voting was performed. RESULTS Consensus (≥80% of agreement) was reached in 20/23 statements. The panel agreed that implant allergy despite being rare should be considered in case of persistent unexplained symptoms. It was, however, recommended to allow adequate time for resolution of symptoms associated with healing and integration of an implant. Obtaining questionnaire-aided standardized medical history and standardized scoring of patient outcomes was also considered an important step by all experts There was broad consensus regarding the utility/performance of patch testing with additional late reading. It was recognized that the lymphocyte transformation test (LTT) has to many limitations to be generally recommended. Prior to orthopaedic implant, allergy screening of patients without a history of potential allergy to implant components was not recommended. CONCLUSIONS Using an expert consensus process, statements concerning allergy diagnostics in suspected metal implant allergy were created. Areas of nonconsensus were identified, stressing uncertainty among the experts around topics such as preoperative testing in assumed allergy, histological correlate of periimplant allergy and in vitro testing, which underscores the need for further research.

Abstract
AIMS To determine the association of micro-metastatic matrix metalloproteinase-2 (MMP-2) expression, the absolute lymphocyte count (ALC)) and outcome in stage II colon cancer. MATERIALS AND METHODS A single centre, prospective observational study, one month post-surgery blood for ALC, circulating tumour cell (CTC) detection and a bone marrow biopsy for micro-metastasis detection were obtained. CTCs were detected using differential gel centrifugation and immunocytochemistry with anti-CEA and anti-MMP-2, the bone marrow biopsy for the detection of micro-metastasis was processed as for CTCs . At each follow-up ALC and CTC counts were determined. Bone marrow sampling was repeated if the ALC decreased by >10%, at relapse or at the end of the study period. Three MRD subgroups were defined, Group I MRD negative, Group II only positive for micro-metastasis and Group III in which CTCs were detected. RESULTS One hundred and eighty one patients participated; 105 (58%) patients formed Group 1, 36 (20%) formed Group II and 40 (22%) formed Group III for a median follow-up of 4 years . Of Group I 3/105 (3%), Group II 16/36 (44%) and Group III 34/40 (84%) patients relapsed. The ALC was significantly higher in Groups I and II, the expression of MMP-2 and MMP-2 score in Group II was significantly lower than in Group III patients. A low ALC was associated with a higher expression of MMP-2 in the micro-metastasis and presence of CTCs. CONCLUSIONS Patients with stable ALCs did not relapse; decreasing ALCs were associated with increasing MMP-2 scores, the appearance of CTCs and relapse.

Abstract
BACKGROUND Artificial intelligence (AI) techniques are promising in early diagnosis of skin diseases. However, a precondition for their success is the access to large-scaled annotated data. Until now, obtaining this data has only been feasible with very high personnel and financial resources. OBJECTIVES The aim of this study was to overcome the obstacle caused by the scarcity of labeled data. METHODS To simulate the scenario of label shortage, we discarded a proportion of labels of the training set. The training set consisted of both labeled and unlabeled images. We then leveraged a self-supervised learning technique to pre-train the AI model on the unlabeled images. Next, we fine-tuned the pre-trained model on the labeled images. RESULTS When the images in the training dataset were fully labeled, the self-supervised pre-trained model achieved 95.7% of accuracy, 91.7% of precision and 90.7% of sensitivity. When only 10% of the data was labeled, the model could still yield 87.7% of accuracy, 81.7% of precision and 68.6% of sensitivity. In addition, we also empirically verified that the AI model and dermatologists are consistent in visually inspecting the skin images. CONCLUSIONS The experimental results demonstrate the great potential of the self-supervised learning in alleviating the scarcity of annotated data.

Abstract
Introduction: Minimal residual disease (MRD) is the net result of the biological properties of disseminated tumour cells and the effect of the immune system and treatment to eliminate them. The aim of this study was to analyse the effect of combined chemotherapy on the immune function as determined by the neutrophil-lymphocyte ratio (NLR) and if it was associated with changes in the subtype of minimal residual disease and outcome in stage III colon cancer. Methods and Patients: A prospective, single centre observational study; the NLR was determined immediately prior to and one, two and three months after completing chemotherapy. Circulating tumour cells (CTCs) and bone marrow micro-metastasis (mM) using immunocytochemistry with anti-CEA were determined prior to and one month after chemotherapy. The association of changes in the NLR with MRD subtypes classified as Group I (negative for CTCs and mM), Group II (positive for mM) and Group III (positive for CTCs) as a result of chemotherapy and five-year disease free progression (DFS) analysed. Results: One hundred and eighty eight patients participated of whom 83 (44.9%) relapsed. In non-relapsing patients the NLR significantly increased and was higher after chemotherapy compared with relapsing patients. Significant increases in the NLR were associated with changes to a better MRD prognostic subtype and decreases with a worse MRD subtype. Neither baseline NLR nor MRD subtype predicted response to chemotherapy. DFS for MRD subgroups were 88%, 56% and 6% for Groups I to III respectively. Conclusions: Immune function as measured by the NLR is associated with MRD prognostic subtypes, improvements in the NLR are associated with improvements in MRD post chemotherapy but neither baseline NLR or MRD predicted outcome.

Abstract
AIM Minimal residual disease (MRD) is the net result of the biological properties of disseminated tumour cells and the effect of the immune system and treatment to eliminate them. The aim of this work is to report the changes in MRD status and immune function (lymphocyte count) after FOLFOX chemotherapy, and the outcome in Stage III colon cancer patients. METHOD This study is a prospective, single-centre observational study. Lymphocyte counts were determined prior to and 1, 2 and 3 months after the completion of chemotherapy. Circulating tumour cells (CTCs) and bone marrow micrometastases were determined using immunocytochemistry with anticarcinoembryonic antigen prior to and 1 month after chemotherapy. MRD was classified as negative (Group I), micrometastasis positive only (Group II) and CTC positive (Group III). Changes in lymphocyte counts and MRD subtype following chemotherapy and relapse-free progression were analysed. RESULTS Of the total of 185 patients, 83 (44.9%) relapsed. The risk of relapse significantly increased from Groups I to III (p < 0.001) and with decreasing lymphocyte count (p < 0.01). The lymphocyte count significantly decreased from Groups I to III (p < 0.001). Multivariance Cox regression analysis showed hazard ratios of 3.58 (Group II), 17.43 (Group III) and 0.39 (lymphocyte count) in predicting relapse. Following chemotherapy, improved lymphocyte count was associated with improved MRD subtype (p < 0.0001). Neither baseline lymphocyte count nor MRD subtype predicted response to chemotherapy. Five-year relapse-free survival for combined lymphocyte-MRD subtypes was 95%, 57% and 5% for Groups I to III, respectively (p < 0.001). CONCLUSION Following chemotherapy, improvements in immune function were associated with improved MRD subtype and a better relapse-free survival.

Abstract
BACKGROUND Ex vivo confocal laser scanning microscopy (CLSM) enables bedside histology and offers the surgeon a direct intraoperative tissue examination. OBJECTIVES To determine whether this innovative, ultra-fast diagnostic tool can be expanded beyond nonmelanoma skin cancer, particularly basal cell carcinoma, to other indications including melanocytic lesions and autoimmune diseases. MATERIALS AND METHODS Review of literature and summary of the current knowledge and experience of the use of ex vivo CLSM in melanocytic lesions and in autoimmune diseases. RESULTS Up to date experience of the use of ex vivo CLSM in melanocytic lesions and in autoimmune diseases is limited but promising. Current knowledge on melanocytic lesions in ex vivo CLSM and their examples together with classic ex vivo CLSM features are presented. Previous results on the use of ex vivo CLSM in autoimmune dermatoses are presented, and future application possibilities of ex vivo CLSM are discussed. CONCLUSIONS The method is particularly suitable for the rapid examination of basal cell carcinomas during Mohs surgery but could also be used in the future for the intraoperative examination of melanocytic and autoimmune skin lesions.

Abstract
Ticks, notorious blood-feeders and disease-vectors, have lost a part of their genetic complement encoding haem biosynthetic enzymes and are, therefore, dependent on the acquisition and distribution of host haem. Solute carrier protein SLC48A1, aka haem-responsive gene 1 protein (HRG1), has been implicated in haem transport, regulating the availability of intracellular haem. HRG1 transporter has been identified in both free-living and parasitic organisms ranging from unicellular kinetoplastids, nematodes, up to vertebrates. However, an HRG1 homologue in the arthropod lineage has not yet been identified. We have identified a single HRG1 homologue in the midgut transcriptome of the tick Ixodes ricinus, denoted as IrHRG, and have elucidated its role as a haem transporter. Data from haem biosynthesis-deficient yeast growth assays, systemic RNA interference and the evaluation of gallium protoporphyrin IX-mediated toxicity through tick membrane feeding clearly show that IrHRG is the bona fide tetrapyrrole transporter. We argue that during evolution, ticks profited from retaining a functional hrg1 gene in the genome because its protein product facilitates host haem escort from intracellularly digested haemoglobin, rendering haem bioavailable for a haem-dependent network of enzymes.

Abstract
BACKGROUND The treatment of keratinocyte cancers (KC) strictly depends on their differentiation and invasiveness. Non-invasive diagnostic techniques can support the diagnosis in real time, avoiding unnecessary biopsies. This study aimed to preliminarily define main imaging criteria and histological correlations of actinic keratosis (AK), Bowen's disease (BD) and squamous cell carcinoma (SCC) using the novel device line-field confocal optical coherence tomography (LC-OCT). METHODS Dermoscopy and LC-OCT images of 73 histopathologically confirmed lesions (46 AKs, 11 BD and 16 SCCs) were included in the study. Exemplary lesions (10 AKs, 5 BD and 5 SCCs) were additionally investigated with optical coherence tomography and reflectance confocal microscopy. RESULTS Most common LC-OCT findings of KC in the descriptive statistics were hyperkeratosis/parakeratosis, disruption of stratum corneum, broadened epidermis, basal and suprabasal keratinocyte atypia, dilated vessels/neoangiogenesis and elastosis/collagen alterations. In the univariate multinomial logistic regression, a preserved DEJ was less common in SCC compared with AK and BD, BD displayed marked keratinocyte atypia involving all epidermal layers (bowenoid pattern), while SCC showed ulceration, increased epidermal thickness, keratin plugs, acantholysis, not visible/interrupted DEJ and epidermal bright particles. LC-OCT increased the diagnostic confidence by 24.7% compared with dermoscopy alone. CONCLUSIONS Our study describes for the first time specific LC-OCT features of different stages of KC and their histopathological correlates, focusing on keratinocyte morphology and architecture of the epidermis and DEJ. LC-OCT may open new scenarios in the bedside diagnosis, treatment planning and follow-up of KC.

Abstract
BACKGROUND Behçet's disease (BD) presents with lymphocytic and neutrophilic vasculitis of unknown aetiology. HLA-B*51 ERAP1 and IL12R/IL23R are genetic risk factors. IL-23 regulates IL-17A, which controls recruitment and activation of neutrophils. OBJECTIVES To determine pathological changes in BD skin lesions related to the complex genetic predisposition METHODS: We characterised the expression of IL-17A and IL-23A in various cell types by immunohistological double staining of sections from papulopustular skin lesions (PPL) of acute attacks of BD and lesions of psoriasis vulgaris (PV), another HLA-class I-associated T-cell mediated autoimmune disease in which excessive T-cell derived IL-17A production promotes neutrophil activation. RESULTS We found that in BD lesions, as in psoriasis, actively expanding CD8+ T cells were the predominant source of IL-17A. IL-17A+ CD8+ T (Tc17) cells outnumbered infiltrating IL-17A+ CD4+ T cells. Unlike the epidermal localisation of CD8+ T cells in psoriasis, Tc17 cells in BD lesions infiltrated mainly the perivascular tissue and also the blood vessel walls of dermis and subcutaneous tissue. They colocalised with a marked IL-23A expression by CD11c+ dendritic cells (DCs) and CD68+ macrophages. IL-17A expression was associated with extensive recruitment of neutrophils around blood vessels that formed neutrophil extracellular traps (NETs). CONCLUSIONS In BD, the genetic predisposition may mediate antigen-specific activation and differentiation of a Tc 17 response, possibly targeting endothelial antigens. Neutrophils recruited by IL-17A in this process may enhance tissue damage by extensive NET formation (NETosis). Thus, the IL-23/IL-17 axis presumably controls neutrophilic inflammation in BD vasculitis in the context of a predominant antigen-specific CD8+ T-cell response.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is the most common skin cancer in the general population. Treatments vary from Mohs surgery to topical therapy, depending on the subtype. Dermoscopy, reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) have gained a foothold in daily clinical practice to optimize diagnosis and subtype-oriented treatment. The new device Line-field confocal OCT (LC-OCT) allows imaging at high resolution and depth but its use is not yet been investigated in larger studies. OBJECTIVES To evaluate the main LC-OCT criteria for the diagnosis and subtyping of BCC in comparison to histopathology, OCT and RCM. METHODS Fifty-two histopathologically confirmed BCCs were evaluated for imaging criteria. Their frequency, predictive values and ROC curves were calculated. A multinominal regression with stepwise variables selection to distinguish BCC subtypes was performed. RESULTS Nodular BCCs were mainly characterized by atypical keratinocytes, altered DEJ, tumour nests in the dermis, dark clefting, prominent vascularisation and white hyperreflective stroma. Superficial BCCs showed a thickening of the epidermis due to a series of tumour lobules with clear connection to the DEJ (string of pearls pattern). Infiltrative BCCs were characterized by elongated hyporeflective tumour strands, surrounded by bright collagen (shoal of fish). The overall BCC subtype agreement between LC-OCT and conventional histology was 90.4 % (95% CI: 79.0, 96.8). CONCLUSION LC-OCT allows the non-invasive, real time identification of BCCs and their subtypes in vertical, horizontal and 3D mode compared to histology, RCM and OCT. Further larger studies are needed to better explore the clinical applications of this promising device.

Abstract
An ion cyclotron emission (ICE) diagnostic is prepared for installation into the W7-X stellarator, with the aim to be operated in the 2022 experimental campaign. The design is based on the successful ICE diagnostic on the ASDEX Upgrade tokamak. The new diagnostic consists of four B-dot probes, mounted about 72° toroidally away (one module) from the neutral beam injector, with an unobstructed plasma view. Two of the B-dot probes are oriented parallel to the local magnetic field, aimed to detect fast magnetosonic waves. The remaining two probes are oriented poloidally, with the aim to detect slow waves. The radio frequency (RF) signals picked up by the probes are transferred via 50 Ω vacuum-compatible coaxial cables to RF detectors. Narrow band notch filters are used to protect the detectors from possible RF waves launched by the W7-X antenna. The signal will be sampled with a four-channel fast analog-to-digital converter with 14 bit depth and 1 GSample/s sampling rate. The diagnostic's phase-frequency characteristic is properly measured in order to allow measuring the wave vectors of the picked up waves.

Abstract
The Charge Exchange Recombination Spectroscopy (CXRS) diagnostic has become a routine diagnostic on almost all major high temperature fusion experimental devices. For the optimized stellarator Wendelstein 7-X (W7-X), a highly flexible and extensive CXRS diagnostic has been built to provide high-resolution local measurements of several important plasma parameters using the recently commissioned neutral beam heating. This paper outlines the design specifics of the W7-X CXRS system and gives examples of the initial results obtained, including typical ion temperature profiles for several common heating scenarios, toroidal flow and radial electric field derived from velocity measurements, beam attenuation via beam emission spectra, and normalized impurity density profiles under some typical plasma conditions.

Abstract
INTRODUCTION Surgery in SCLC is limited to very early stages, but several reports suggest a potential broader role. Little is known of the influence of microenvironment on the biology of SCLC. METHODS We assessed the clinical prognostic factors in a large series of resected SCLC patients. The prognostic value of programmed cell death ligand 1 (PD-L1) expression in tumor cells and tumor infiltrating lymphocytes (TILs) and the percentage of CD3-, CD20-, CD45- and CD68-positive cells, were also investigated. RESULTS Two hundred five SCLC cases were resected between 2005 and 2015 and the median follow-up was 29 months (range: 2 to 135 months). Median survival of all patients was 69 months, and 5-year survival rates were 63.8%, 65.5%, 34.9%, and 0% for pathologic stages I, II, III, and IV, respectively. By multivariate analysis complete resection, cigarette index, lymph node metastatic rate, percentage of CD3-positive cells, PD-L1 expression in tumor cells, and TILs were independent prognostic factors. High PD-L1 expression was present in 3.2% and 33.5% of all tumor samples in tumor cells and TILs, respectively. High PD-L1 expression in tumor cells or TILs correlated with shorter survival, whereas high expression of CD3, CD20, and CD45 correlated with better survival. CONCLUSIONS Resected stage II SCLC patients have similar survival as stage I, suggesting that surgery could be extended to patients with hilar lymph node involvement. Survival was better in tumors with a higher percentage of T cells and B cells, whereas PD-L1 expression in tumor cells and TILs correlated with worse survival, which suggests a potential role of immunotherapy in resected SCLC.

Abstract
Using conditional cell reprogramming, we generated a stable cell culture of an extremely rare and aggressive neuroendocrine cervical cancer. The cultured cells contained HPV-16, formed colonies in soft agar and rapidly produced tumors in immunodeficient mice. The HPV-16 genome was integrated adjacent to the Myc gene, both of which were amplified 40-fold. Analysis of RNA transcripts detected fusion of the HPV/Myc genes, arising from apparent microhomologous recombination. Spectral karyotyping (SKY) and fluorescent-in-situ hybridization (FISH) demonstrated coordinate localization and translocation of the amplified Myc and HPV genes on chromosomes 8 and 21. Similar to the primary tumor, tumor cell cultures expressed very high levels of the Myc protein and, in contrast to all other HPV-positive cervical cancer cell lines, they harbored a gain-of-function mutation in p53 (R273C). Unexpectedly, viral oncogene knockdown had no effect on the growth of the cells, but it did inhibit the proliferation of a conventional HPV-16 positive cervical cancer cell line. Knockdown of Myc, but not the mutant p53, significantly inhibited tumor cell proliferation. On the basis of these data, we propose that the primary driver of transformation in this aggressive cervical cancer is not HPV oncogene expression but rather the overexpression of Myc.

Abstract
Metal implant sensitivity (intolerance) can cause pain, reduced mobility, loosening of the implant and skin rashes. Knowledge of differential diagnoses, histology and appropriate diagnostics are essential for proper diagnosis. To outline typical clinical signs and histology in metal-implant-associated skin lesions we present three exemplary patients from our implant allergy outpatient department and give an overview of the current literature regarding metal implant sensitivity. In patients with a negative patch test the lymphocyte transformation test may reveal metal sensitization. Even "pure" titanium alloys may contain traces of nickel. The histology of implant-associated skin reactions goes from teleangiectatic postimplantation erythema to eczema and vasculitis. Based on the synopsis of history, clinical picture, allergological testing and histology, metal implant sensitivity can be diagnosed more precisely.

Abstract
Wendelstein 7-X, a superconducting optimized stellarator built in Greifswald/Germany, started its first plasmas with the last closed flux surface (LCFS) defined by 5 uncooled graphite limiters in December 2015. At the end of the 10 weeks long experimental campaign (OP1.1) more than 20 independent diagnostic systems were in operation, allowing detailed studies of many interesting plasma phenomena. For example, fast neutral gas manometers supported by video cameras (including one fast-frame camera with frame rates of tens of kHz) as well as visible cameras with different interference filters, with field of views covering all ten half-modules of the stellarator, discovered a MARFE-like radiation zone on the inboard side of machine module 4. This structure is presumably triggered by an inadvertent plasma-wall interaction in module 4 resulting in a high impurity influx that terminates some discharges by radiation cooling. The main plasma parameters achieved in OP1.1 exceeded predicted values in discharges of a length reaching 6 s. Although OP1.1 is characterized by short pulses, many of the diagnostics are already designed for quasi-steady state operation of 30 min discharges heated at 10 MW of ECRH. An overview of diagnostic performance for OP1.1 is given, including some highlights from the physics campaigns.

Abstract
STUDY AIM To describe the main technical characteristics of biologic prostheses used for parietal reinforcement and to present the state of the art on their risk/benefit ratio. METHODS We conducted a technical analysis of manufacturer specifications of the biologic prostheses that are currently available in France accompanied by a literature review by selecting meta-analyses and systematic reviews, randomized controlled trials and publications of health technology rating agencies. RESULTS Biological implants for parietal reinforcement are mainly intended for use in a contaminated environment where the use of synthetic prostheses is contra-indicated. We identified fourteen systematic reviews and meta-analyses and one randomized controlled trial. Six ongoing clinical trials were identified as well as two clinical trials that had been interrupted. In the current state of knowledge, there are no high-level evidence data on the therapeutic contribution of biologic prostheses that allow prioritization of the various biologic prostheses according to their characteristics or their different manufacturing processes. CONCLUSION Pending the results of current randomized controlled trials to validate the indications and an eventual specific reimbursement, indications for the use of biologic parietal reinforcement prostheses seems to be limited to rare clinical situations and only after collegial discussion.

Abstract
BACKGROUND Optical coherence tomography (OCT) has become a valuable non-invasive tool in the in vivo diagnosis of non-melanoma skin cancer, especially of basal cell carcinoma (BCC). Due to an updated software-supported algorithm, a new en-face mode - similar to the horizontal en-face mode in high-definition OCT and reflectance confocal microscopy - surface-parallel imaging is possible which, in combination with the established slice mode of frequency domain (FD-)OCT, may offer additional information in the diagnosis of BCC. OBJECTIVES To define characteristic morphologic features of BCC using the new en-face mode in addition to the conventional cross-sectional imaging mode for three-dimensional imaging of BCC in FD-OCT. METHODS A total of 33 BCC were examined preoperatively by imaging in en-face mode as well as cross-sectional mode in FD-OCT. Characteristic features were evaluated and correlated with histopathology findings. RESULTS Features established in the cross-sectional imaging mode as well as additional features were present in the en-face mode of FD-OCT: lobulated structures (100%), dark peritumoral rim (75%), bright peritumoral stroma (96%), branching vessels (90%), compressed fibrous bundles between lobulated nests ('star shaped') (78%), and intranodular small bright dots (51%). These features were also evaluated according to the histopathological subtype. In the en-face mode, the lobulated structures with compressed fibrous bundles of the BCC were more distinct than in the slice mode. CONCLUSION FD-OCT with a new depiction for horizontal and vertical imaging modes offers additional information in the diagnosis of BCC, especially in nodular BCC, and enhances the possibility of the evaluation of morphologic tumour features.

Abstract
WHAT IS NEW AND OBJECTIVES Trends in the care of glioblastoma in actual practice settings are poorly described. In a previous pharmacoepidemiologic study, we highlighted changes in the management of patients with glioblastoma (GBM) newly diagnosed between 2004 and 2008. Our aim was to complete and to extend the previous report with a study of a cohort of patients diagnosed in 2011 to emphasize the trends in the pharmacotherapy of GBM over the last decade. METHODS A single-centre study was undertaken of three historic cohorts of GBM patients newly diagnosed during years 2004, 2008 and 2011 (corresponding to groups 1, 2 and 3, respectively) but limited to patients eligible for radiotherapy after initial diagnosis. The type of medical management was described and compared, as well as overall survival and total cost from diagnosis to death or the last follow-up date. Cost analysis was performed from the French sickness fund perspective using tariffs from 2014. RESULTS Two hundred and seventeen patients (49 in Group 1, 73 in Group 2, 95 in Group 3) were selected with similar baseline characteristics. Fluorescence-guided surgery using 5-ALA was increasingly used over the three periods. There was a strong trend towards broader use of temozolomide radiochemotherapy (39%, 73% and 83% of patients, respectively) as first-line treatment as well as bevacizumab regimen at recurrence (6%, 48% and 58% of patients, respectively). The increase in overall survival between Group 2 and Group 1 was confirmed for patients in Group 3 (17·5 months vs. 10 months in Group 1). The mean total cost per patient was 53368 € in Group 1, 70 201 € in Group 2 and 78355 € in Group 3. Hospital care represented the largest expenditure (75%, 59% and 60% in groups 1, 2 and 3, respectively) followed by chemotherapy drug costs (11%, 30% and 29%, respectively). WHAT IS NEW AND CONCLUSION This is the first study to report on changes in the management of GBM in real-life practice. The ten-year study indicates an improvement in overall survival but also an increase in total cost of care. The data should be useful for informing the care of GBM patients in settings similar to ours.

Abstract
The objective of this study was to determine whether cervicitis in dairy cows is an independent disease or occurs concomitantly with inflammation of the uterus, and to clarify possible effects of cervicitis on reproductive performance. Dairy cows (n = 416) from 33 dairy farms were examined by rectal palpation and vaginoscopy between 42 and 50 days postpartum. Inclusion criteria for this study were absence of abnormal vaginal discharge and abnormalities of the uterus (fluctuation) at rectal palpation. Cervicitis was diagnosed when the second cervical fold was swollen and prolapsed with (C2) or without (C1) reddening. Cytobrush samples from the uterus (n = 370) and the cervix (n = 402) were collected, and the percentage of neutrophils in the uterus (PMNU) and the cervix as indicators of inflammation (threshold: ≥5%) was determined. In addition, endometrial biopsies for histology were collected, 300 of which were suitable for evaluation. Cervicitis (C1/C2) was diagnosed in 253 of 416 (60.8%) of cows. Of these, the prolapsed cervical mucosa was hyperemic (C2) in 29.1% of cases. Of 370 available uterine cytology samples, 221 cows had a clinical cervicitis; however, 170 (76.9%) had PMNU less than 5%. Of 300 uterine histologic examinations, 82 (27.3%) did not reveal any abnormalities; the remaining cows either had uterine inflammation and/or degenerative uterine changes such as endometriosis and angiosclerosis. Furthermore, of 300 biopsied animals, 184 revealed a cervicitis (C1/C2); however, 30.4% of these animals had no histopathologic uterine findings. For further analysis, only animals either without histopathologic findings and normal uterine cytology or with solely endometritis (defined as PMNU ≥ 5% and/or positive histopathology of the uterine tissue) were evaluated (n = 157). Of these, 95 cows had cervicitis. Unexpectedly, 63 of 95 (66.3%) cows had cervicitis without endometritis. With regard to reproductive performance, days to first service were not affected by cervicitis. Number of days open in animals with cervicitis but without endometritis tended to be lower than in cows with cervicitis plus endometritis (P = 0.092). Also, number of days open relative to percentage of neutrophils greater than 5% was lower when the cervical compared to the uterine mucosa was affected (P < 0.05). Total conception and pregnancy rates of animals 200 days into lactation decreased significantly in cows with severe cervical inflammation (C2). In conclusion, the results of this study suggested that cervicitis occurs independent of endometritis, and a higher degree of cervicitis is associated with poorer reproductive performance.

Abstract
BACKGROUND Esthetic interventions are an integral part of today's dermatology. A plethora of novel agents and techniques is currently being launched on the market accompanied by a variety of side effects. METHOD We summarize the most common adverse events of fillers, laser treatments, and injection of botulinum toxin and present feasible means of prevention and management. RESULTS The profile of adverse events is more favorable in temporary fillers such as hyaluronic acid than in permanent ones. The most common filler-related adverse events include changes of skin color and unspecific swelling. Neural and vascular dysfunctions are observed less frequently, but may result in severe tissue necrosis or loss of vision. Undesirable events of laser treatments largely depend on the applied modality, localization, and indication. Local effects comprise erythema, swelling, crusting, blister formation, and weeping in extreme cases. The formation of laser-induced scarring is more likely to occur in lasers with high energies. Most adverse events of botulinum toxin are mild and transient. Pain and redness around the sites of injection are common. However, a poor injection technique and injection of too many units can trigger major motoric impairment with ptosis and dysarthria. CONCLUSION Excellent results can be achieved with esthetic interventions. To guarantee a maximum amount of safety and to minimize risks it is of paramount importance to work with clear indications and respect contraindications. It is important to recognize early adverse events to achieve satisfactory results and avoid severe complications.

Abstract
BACKGROUND Heparin, the standard perioperative anticoagulant for the prevention of graft vessel thrombosis in patients undergoing liver transplantation (LT), binds to the chemokine platelet factor 4 (PF4). Antibodies that are formed against the resulting PF4/heparin complexes can induce heparin-induced thrombocytopenia. LT is a clinical situation that allows the study of T-cell dependency of immune responses because T-cell function is largely suppressed pharmacologically in these patients to prevent graft rejection. OBJECTIVES To investigate the immune response against PF4/heparin complexes in patients undergoing LT. PATIENTS AND METHODS In this prospective cohort study, 38 consecutive patients undergoing LT were systematically screened for anti-PF4/heparin antibodies (enzyme immunoassay and heparin-induced platelet aggregation assay), platelet count, liver function, and engraftment. RESULTS At baseline, 5 (13%) of 38 patients tested positive for anti-PF4/heparin IgG (non-platelet-activating) antibodies. By day 20, an additional 5 (15%) of 33 patients seroconverted for immunoglobulin G (two platelet-activating) antibodies. No patient developed clinical heparin-induced thrombocytopenia. Two of six patients with graft function failure had anti-PF4/heparin IgG antibodies at the time of graft function failure. Graft liver biopsy samples from these patients showed thrombotic occlusions of the microcirculation. CONCLUSIONS Anti-PF4/heparin IgG antibodies are generated despite strong pharmacologic suppression of T cells, indicating that T cells likely have a limited role in the immune response to PF4/heparin complexes in humans.

Abstract
UNLABELLED HISTORY UND CLINICAL FINDINGS: Within a few weeks, two patients aged 16 and 75 years with fever of unknown origin were referred to the emergency unit. INVESTIGATIONS Laboratory tests revealed increased aminotransferase levels, progressive cytopenia and an increase of inflammatory markers. In the older patient a rapid clinical detoriation with multi organ failure was observed. Progressively increasing levels of ferritin and soluble-interleukin-2-receptor levels led to the diagnosis of hemophagocytic lymphohistiocytosis, which was confirmed by bone marrow examination in the case of the younger patient. TREATMENT AND COURSE Immunsuppressive treatment induced a clear improvement of clinical and laboratory findings and in the case of the older patient finally led to convalescence. CONCLUSION Hemophagocytic lymphohistiocytosis is a rare but potentially fatal differential diagnosis, which should be considered in patients with fever and cytopenia.
