Abstract
Anorectal malformations (ARMs) constitute a group of congenital defects of the gastrointestinal and urogenital systems. They affect males and females, with an estimated worldwide prevalence of 1 in 5000 live births. These malformations are clinically heterogeneous and can be part of a syndromic presentation (syndromic ARM) or as a nonsyndromic entity (nonsyndromic ARM). Despite the well-recognized heritability of nonsyndromic ARM, the genetic etiology in most patients is unknown. In this study, we describe three siblings with diverse congenital anomalies of the genitourinary system, anemia, delayed milestones, and skeletal anomalies. Genome sequencing identified a novel, paternally inherited heterozygous Caudal type Homeobox 2 (CDX2) variant (c.722A > G (p.Glu241Gly)), that was present in all three affected siblings. The variant identified in this family is absent from population databases and predicted to be damaging by most in silico pathogenicity tools. So far, only two other reports implicate variants in CDX2 with ARMs. Remarkably, the individuals described in these studies had similar clinical phenotypes and genetic alterations in CDX2 CDX2 encodes a transcription factor and is considered the master regulator of gastrointestinal development. This variant maps to the homeobox domain of the encoded protein, which is critical for interaction with DNA targets. Our finding provides a potential molecular diagnosis for this family's condition and supports the role of CDX2 in anorectal anomalies. It also highlights the clinical heterogeneity and variable penetrance of ARM predisposition variants, another well-documented phenomenon. Finally, it underscores the diagnostic utility of genomic profiling of ARMs to identify the genetic etiology of these defects.

Abstract
Current practices vary widely regarding the immunological work-up and management of patients affected with defects in thymic development (DTD), which include chromosome 22q11.2 microdeletion syndrome (22q11.2del) and other causes of DiGeorge syndrome (DGS) and coloboma, heart defect, atresia choanae, retardation of growth and development, genital hypoplasia, ear anomalies/deafness (CHARGE) syndrome. Practice variations affect the initial and subsequent assessment of immune function, the terminology used to describe the condition and immune status, the accepted criteria for recommending live vaccines, and how often follow-up is needed based on the degree of immune compromise. The lack of consensus and widely varying practices highlight the need to establish updated immunological clinical practice guidelines. These guideline recommendations provide a comprehensive review for immunologists and other clinicians who manage immune aspects of this group of disorders.

Abstract
The tributaries flowing through Leamington, Ontario are unique in the Canadian Lake Erie watershed due to the broad spatial extent of greenhouse operations, which more than doubled in size and density from 2011 to 2022. These greenhouse operations are considered to be potential nutrient point sources with respect to observed nutrient concentrations in tributaries adjacent to greenhouse stormwater retention ponds (GSWPs). Identifying causal factors of nutrient release, whether this be chemical or biological, within these ponds may be critical for mitigating their impact on the watershed and ultimately the receiving waters of Lake Erie. Specifically, phosphorus and nitrogen accumulation in freshwater ponds can contribute to environmental damage proximal to adjacent streams, serving as a potential catalyst for algal blooms and eutrophication. This study compared correlations between the water column N:P stoichiometry, sediment nutrient retention capacity, and drivers of microbial metabolism within GSWP sediments. Correlations between water column TN:TP ratios and sediment nutrient retention capacity were observed, suggesting an interplay between N and P in terms of nutrient limitation. Further, clear shifts were observed in the bacterial metabolic pathways analyzed through metatranscriptomics. Specifically, genes related to nitrogen fixation, nitrification and denitrification, and other metabolic processes involving sulfur and methane showed differential expression depending on the condition of the respective pond (i.e., naturalized wetland vs. dredged, eutrophic pond). Collectively, this research serves to highlight the interconnected role of chemical-biological processes particularly as they relate to significant ecosystem processes such as nutrient loading and retention dynamics in impaired freshwater systems.

Abstract
Superfluid ^{4}He (He II) is a widely studied model system for exploring finite-size effects in strongly confined geometries. Here, we study He II confined in millimeter-scale channels of 25 and 50 nm height at high pressures using a nanofluidic Helmholtz resonator. We find that the superfluid density is measurably suppressed in the confined geometry from the transition temperature down to 0.6 K. Importantly, this suppression can be accounted for by rotonlike thermal excitations with an energy gap of 5 K. We show that the surface-bound excitations lead to the previously unexplained lack of finite-size scaling of suppression of the superfluid density.

Abstract
Introduction
Previous neuroimaging studies of individuals with nonsyndromic oral clefts have revealed subtle brain structural differences compared to matched controls. Additional studies strongly suggest that the higher incidence of neuropsychiatric issues observed in these individuals may be explained by these neuroanatomical differences. Currently there are no studies that have assessed the overall empirical evidence of the effect of oral clefts on the brain. Objectives
Our aim was to summarize available evidence on potential brain structure differences in individuals with nonsyndromic oral clefts and their matched controls. In the current presentation, we discuss the results of regional brain structural differences. Methods
Five databases were systematically searched in September 2020 for case-control studies that reported neuroimaging in healthy individuals and individuals with nonsyndromic oral clefts. Duplicate study selection, data extraction, random effects meta-analyses of mean differences (MDs) and their 95% confidence intervals were performed in order to compare regional brain MRI volumes. Results
We have identified 245 records following the database searches, from which 12 records met the inclusion criteria. Quantitative data on brain structure were available in three studies.The cerebellum, occipital and temporal lobes were significantly smaller in the cleft group compared to controls (MD: -12.46, 95% CI: -18.26, -6.67, n=3 studies; MD:-7.39, 95% CI: -12.80, -1.99, n=2 studies; MD: -10.53, 95% CI: -18.23, -2.82, n=2 studies, respectively). Conclusions There may be structural brain differences between individuals with nonsyndromic oral clefts and their controls based on the available evidence. Disclosure No significant relationships.

Abstract
Introduction
Following the mentalization of interpersonal relations can be improved through reading for which the influence of literary fiction can also serve as a model. Schizophrenia is characterized by extensive deficits in mentalization, and the amelioration of these impairments is a major focus in psychosocial treatment research. Reading literature can be a potential tool in improving mentalizing skills.
Objectives
We aimed to examine and compare healthy participants with patients living with schizophrenia, focusing on measuring mentalizing skills and the impact of reading literary fiction on their mentalization skills.
Methods
47 persons with schizophrenia in remission and 48 healthy controls were assessed and compared with Short Story Task (SST) a new measurement of ToM. SST proved to be a sensitive tool, to individual differences. After reading the short story “The End of Something” (Hemingway) a structured interview was done with 14 questions.
Results
We found that patients with schizophrenia performed significantly worse in their ToM scores compared to healthy controls (ANOVA test, p<0,05 ). Previous reading experiences correlated significantly with mentalizing scores not just in healthy controls (Independent Samples T-test, p<0,05) but also in patients with schizophrenia. ToM scores were twice as high among those who had prior reading experiences in the schizophrenia group ((MS= 3,91, SD=3,166, M=8,08, SD=4,542; p<0,05, t=-3,509).
Conclusions
We found that mentalization skills could be improved by regular reading. Our results could also be influenced by several other factors such as empathy skills, identification with the characters etc. Our results and conclusions are in line with the results of international research on this topic.
Disclosure
No significant relationships.

Abstract
Introduction Everyday social interactions are based on Theory of Mind (ToM) or mentalizing, whose complex processes are involved in understanding, representing one’s own and other people’s mental states. ToM is supposed to have two systems. The implicit ToM seems to be a fast, automatic, non-verbal processing. The explicit ToM is characterized by a slower, but more flexible processing, which is mostly verbal, interpretative. Several studies have described explicit ToM deficit in schizophrenic patients. Less research has investigated implicit ToM in patients, however recently, there has been a growing number of articles examining implicit ToM of patients with schizophrenia. Objectives The aim of our systematic review and meta-analysis is to summarize the results of the implicit ToM in schizophrenia. Methods A systematic search was performed in four major databases. We included 11 publications. 7 studies; and 5 studies were included the quantitative synthesis and the qualitative synthesis, respectively. Results We found significant differences in accuracy, reaction time and brain activation patterns during implicit ToM between schizophrenic patients and controls. The systematic review revealed further alterations in visual scanning, cue fixation, face looking time, and difficulties in perspective taking. Conclusions Based on our results implicit ToM is affected in schizophrenia in addition to explicit ToM deficit. However, based on these results we cannot exclude the possibility, that implicit ToM or at least some elements of it might be relatively unaffected (e.g. detection of intentionality), however its effectiveness is limited by non-mentalizing deficits (e.g. certain neurocognitive impairments). Our results may have important implications for the remediation of mentalizing skills.

Abstract
Introduction
Theory of Mind is the ability to attribute mental states to others. Investigations have distinguished implicit and explicit forms of ToM. It is known, that patients with schizoprenia have deficits in their explicit ToM, and they also show altered brain activations during examining explicit ToM.
Objectives
In this study our aim was to investigate the underlying neural substrates of implicit ToM in patients with schizophrenia with fMRI.
Methods
Seven healthy subjects and two patients with first episode schizophrenia were involved. We used: false belief condition and control condition. All movies consisted of a belief formation phase and an outcome phase. The belief formation phase started with an agent placing a ball on a table in front of an occluder. Then the ball rolled behind the occluder. The movies could continue in different ways leading to a true or false belief. At the end of each movie, the agent reentered the scene and the occluder was lowered. In the outcome phase the ball was either present or absent behind the occluder. The control conditions started with a ball rolled behind the occluder on a table ended up with two different ways as the ball was either present or absent behind the occluder. There was no agent in the control movies.
Results
We found that healthy subjects activated significantly stronger the left lingual gyrus as well as the right temporoparietal junction.
Conclusions
Our findings suggest deficits in implicit ToM in schizophrenia and our findings also might help to clarify the underlying neural substrates of implicit ToM.

Abstract
BACKGROUND Peanut allergy has a rising prevalence in high-income countries, affecting 0.5%-1.4% of children. This study aimed to better understand peanut anaphylaxis in comparison to anaphylaxis to other food triggers in European children and adolescents. METHODS Data was sourced from the European Anaphylaxis Registry via an online questionnaire, after in-depth review of food-induced anaphylaxis cases in a tertiary paediatric allergy centre. RESULTS 3514 cases of food anaphylaxis were reported between July 2007 - March 2018, 56% in patients younger than 18 years. Peanut anaphylaxis was recorded in 459 children and adolescents (85% of all peanut anaphylaxis cases). Previous reactions (42% vs. 38%; p = .001), asthma comorbidity (47% vs. 35%; p < .001), relevant cofactors (29% vs. 22%; p = .004) and biphasic reactions (10% vs. 4%; p = .001) were more commonly reported in peanut anaphylaxis. Most cases were labelled as severe anaphylaxis (Ring&Messmer grade III 65% vs. 56% and grade IV 1.1% vs. 0.9%; p = .001). Self-administration of intramuscular adrenaline was low (17% vs. 15%), professional adrenaline administration was higher in non-peanut food anaphylaxis (34% vs. 26%; p = .003). Hospitalization was higher for peanut anaphylaxis (67% vs. 54%; p = .004). CONCLUSIONS The European Anaphylaxis Registry data confirmed peanut as one of the major causes of severe, potentially life-threatening allergic reactions in European children, with some characteristic features e.g., presence of asthma comorbidity and increased rate of biphasic reactions. Usage of intramuscular adrenaline as first-line treatment is low and needs to be improved. The Registry, designed as the largest database on anaphylaxis, allows continuous assessment of this condition.

Abstract
Infantile fibrosarcoma (IFS) is nearly universally driven by gene fusions involving the NTRK family. ETV6-NTRK3 fusions account for ∼85% of alterations; the remainder are attributed to NTRK-variant fusions. Rarely, other genomic aberrations have been described in association with tumors identified as IFS or IFS-like. We describe the utility of genomic characterization of an IFS-like tumor. We also describe the successful treatment combination of VAC (vincristine, actinomycin, cyclophosphamide) with tyrosine kinase inhibitor (TKI) maintenance in this entity. This patient presented at birth with a right facial mass, enlarging at 1 mo to 4.9 × 4.5 × 6.3 cm. Biopsy demonstrated hypercellular fascicles of spindle cells with patchy positivity for smooth muscle actin (SMA) and negativity for S100, desmin, myogenin, and MyoD1. Targeted RNA sequencing identified a novel RBPMS-MET fusion with confirmed absence of ETV6-NTRK3, and the patient was diagnosed with an IFS-like tumor. A positron emission tomography (PET) scan was negative for metastatic disease. VAC was given for a duration of 10 mo. Resection at 13 mo of age demonstrated positive margins. Cabozantinib, a MET-targeting TKI, was initiated. The patient tolerated cabozantinib well and has no evidence of disease at 24 mo of age. We describe a novel RBPMS-MET driver fusion in association with a locally aggressive IFS-like tumor. MET functions as an oncogene and, when associated with the RNA binding protein RBPMS, forms an in-frame fusion product that retains the MET kinase domain. This fusion is associated with aberrant cell signaling pathway expression and subsequent malignancy. We describe treatment with cabozantinib in a patient with an IFS-like neoplasm.

Abstract
Turbulent flow restricted to two dimensions can spontaneously develop order on large scales, defying entropy expectations and in sharp contrast with turbulence in three dimensions where nonlinear turbulent processes act to destroy large-scale order. In this work we report the observation of unusual turbulent behavior in steady-state flow of superfluid ^{4}He-a liquid with vanishing viscosity and discrete vorticity-in a nearly two-dimensional channel. Surprisingly, for a range of experimental parameters, turbulence is observed to exist in two bistable states. This bistability can be well explained by the appearance of large-scale regions of flow of opposite vorticity.

Abstract
Sentinel lymph node biopsy (SLNB) is a standard procedure for regional lymph node staging and still has the most important prognostic value for the outcome of patients with thin melanoma. In addition to ulceration, SLNB had to be considered even for a single mitotic figure in thin (<1 mm) melanoma according to AJCC7th guideline, therefore, a retrospective review was conducted involving 403 pT1 melanoma patients. Among them, 152 patients suffered from pT1b ulcerated or mitotic rate ≥ 1/ mm2 melanomas according to the AJCC7th staging system. SLNB was performed in 78 cases, of which nine (11.5%) showed SLN positivity. From them, interestingly, we found a relatively high positive sentinel rate (6/78-8%) in the case of thin primary melanomas ˂0.8 mm. Moreover, the presence of regression increased the probability of sentinel positivity by 5.796 fold. After reassessing pT stage based on the new AJCC8th, 37 pT1b cases were reordered into pT1a category. There was no significant relation between other characteristics examined (age, gender, Breslow, Clark level, and mitosis index) and sentinel node positivity. Based on our data, we suggest that mitotic rate alone is not a sufficiently powerful predictor of SLN status in thin melanomas. If strict histopathological definition criteria are applied, regression might be an additional adverse feature that aids in identifying T1 patients most likely to be SLN-positive. After reassessing of pT1b cases according to AJCC8th regression proved to be independent prognostic factor on sentinel lymph node positivity. Our results propose that sentinel lymph node biopsy might also be considered at patients with regressive thin (˂0.8 mm) melanomas.

Abstract
CARMIL2 deficiency is a rare combined immunodeficiency (CID) characterized by defective CD28-mediated T cell co-stimulation, altered cytoskeletal dynamics, and susceptibility to Epstein Barr Virus smooth muscle tumors (EBV-SMTs). Case reports associated with EBV-SMTs are limited. We describe herein a novel homozygous CARMIL2 variant (c.1364_1393del) in two Saudi Arabian male siblings born to consanguineous parents who developed EBV-SMTs. CARMIL2 protein expression was significantly reduced in CD4+ T cells and CD8+ T cells. T cell proliferation on stimulation with soluble (s) anti-CD3 or (s) anti-CD3 plus anti-CD28 antibodies was close to absent in the proband, confirming altered CD28-mediated co-signaling. CD28 expression was substantially reduced in the proband's T cells, and was diminished to a lesser degree in the T cells of the younger sibling, who has a milder clinical phenotype. Defects in both T and B cell compartments were observed, including absent central memory CD8+ T cells, and decreased frequencies of total and class-switched memory B cells. FOXP3+ regulatory T cells (Treg) were also quantitatively decreased, and furthermore CD25 expression within the Treg subset was substantially reduced. These data confirm the pathogenicity of this novel loss-of-function (LOF) variant in CARMIL2 and expand the genotypic and phenotypic spectrum of CIDs associated with EBV-SMTs.

Abstract
Hypodysfibrinogenemia, the least frequently reported congenital fibrinogen disorder is characterized by low circulating levels of a dysfunctional protein, and is associated with phenotypic features of both hypo- and dysfibrinogenemia. Herein, we report an adolescent male with unprovoked venous thromboembolism and hypodysfibrinogenemia. Patient had recurrent, progressive thrombosis despite therapeutic anticoagulation with both low molecular weight heparin and warfarin. He had clinical and radiological improvement after transition to a direct thrombin inhibitor. Sequencing of the FGG gene identified a novel heterozygous mutation, c.1075G>T. Structural visualization of the identified variant was pursued and suggested that the mutation likely destabilizes the Ca2+ -binding site of fibrinogen resulting in pathogenicity.

Abstract
We present here a case of MIRAGE syndrome due to novel variant (c.2318T>C) in the sterile α motif domain-containing protein 9 (SAMD9) gene. Previous reports have described the clinical phenotype, which includes myelodysplasia, recurrent infections, restriction of growth and development, adrenal insufficiency, genitourinary abnormalities, and enteropathies, often resulting in fatality within the first few years of life. This report illustrates the variability in phenotype by describing an 11-year-old male, diagnosed with MIRAGE at age 9 years when his novel variant was identified through whole exome sequencing. A brief review of previously published cases of MIRAGE syndrome and the genotypic and phenotypic spectrum are presented.

Abstract
Abstract
Medulloblastoma is a pediatric embryonal tumor that can be classified into four molecular subgroups, each derived from a different progenitor cell. It is estimated that about 30-40% of patients will relapse, typically with recurrence at the primary site and of the same molecular subgroup. We present paired tumor/normal genomic analysis of an 18 year-old male who presented with non-Wnt/non-SHH medulloblastoma at age 12 and relapsed with metastatic disease of the falx cerebri 3 years later. Combination surgery, chemotherapy, and radiation were used in treatment of the primary and recurrent tumor. At a timepoint 6 years from original diagnosis, the patient presented with a cerebellar tumor histologically described as “consistent with recurrent medulloblastoma” with comment recommending genomics to confirm. The diagnosis was made based on near identifical morphology and retention of Neu-N and Synaptophysin in the tumor (confirmed by subsequent genetic analysis). The primary tumor and the tumor occurring 6 years after the primary diagnosis were analyzed by whole exome sequencing (blood and tumor tissues) to assess for germline variants, somatic mutation, and copy number variation. We observed no pathogenic germline variants in cancer predisposition genes. The tumor mutational profiles were distinct, with only 6 (1.8%) shared somatic variants between tumors. Specimen provenance was verified by germline variation and SRY coverage. Two targetable mutations within the RAS-MAPK pathway (PTPN11 p.Glu76Lys and PIK3CA p.Gly1007Arg) were present only in the new CNS tumor. Although the primary tumor harbored isochromosome 17q and a gain of chromosome 4, these somatic chromosomal aberrations were not detected in the new CNS tumor. RNA-seq was performed on both tumors and compared to pediatric CNS tumors from the University of California Santa Cruz Treehouse Initiative (n=434). The primary tumor clustered with the medulloblastoma patients by principal component analysis while the new CNS tumor clustered with a group of gliomas and non-medulloblastoma embryonal tumors. The primary tumor displayed evidence of overexpression of Group 4 medulloblastoma genes (e.g. EOMES, RBM24, SNCAIP, and UNC5D). These genes were not overexpressed in the new CNS tumor. Enrichment of genes commonly found in gliomas (e.g. BCAN, CHI3L2, PDGFRA, and SOX2) were noted in the new CNS tumor only. In summary, tumor genomic profiling of a primary medulloblastoma and the new CNS tumor arising 6 years later revealed two distinct sets of somatic mutations suggestive of second malignancy rather than recurrence in this patient. While second malignancy in the setting of medulloblastoma is a rare event, it has been documented, both in a time period consistent with that described in our patient and in the form of glioma. Thus, tumor profiling refined diagnosis in this patient allowing for a more accurate assessment of treatment and management options.

Abstract
Klippel-Feil syndrome (KFS) is an exceedingly rare constitutional disorder in which a paucity of knowledge exists about the disease and its associated morbidity and mortality. We present a 4-year-old male with KFS, who notably was also diagnosed with large-cell anaplastic medulloblastoma. We evaluated the genetic basis of co-occurring KFS and medulloblastoma and the role of MYO18B as related to medulloblastoma. Constitutional and somatic variant and copy number analyses were performed from DNA-based exome studies, along with RNA-sequencing of tumor tissue, to elucidate the genetic etiology of the co-existing disease states. We identified novel constitutional compound heterozygous frameshift variants (NM_032608.5: p.Leu2257SerfsTer16 and p.Arg2220SerfsTer74) each encoding a premature stop of translation in MYO18B, consistent with a diagnosis of KFS. We did not identify any somatic variants of known relevance or disease-relevant therapeutic targets in the tumor. The somatic copy number profile was suggestive of Group 3γ medulloblastoma. Relative to pediatric brain tumors, medulloblastoma, particularly, Group 3, had increased gene expression of MYO18B. In summary, coexisting constitutional and somatic diagnoses in this patient enabled the elucidation of the genetic etiology of KFS and provided support for the role of MYO18B in tumor suppression.

Abstract
Immunoassay based techniques are an important and fast option for the detection and quantification of mycotoxins. They are frequently used as on-site screening tools in grain elevators, storage and production facilities. However, accurate quantification may be hampered by the co-recognition of structurally related metabolites by the used antibodies. Therefore, it is crucial to assess their cross-reactivity to avoid misinterpretation of the results. Several immunoassays for the determination of deoxynivalenol (DON) are commercially available. Recently, novel trichothecene mycotoxins with structures similar to DON, the NX-toxins (NX-2, NX-3 and NX-4), were discovered, which can potentially co-occur with DON in cereals. So far, no data about the cross-reactivity of those toxins with DON-antibodies are available. The aim of this study was to assess the cross-reactivities of NX-toxins and some other DON-related metabolites with DON-antibodies in buffer solutions. Six commercially available enzyme-linked immunosorbent assays (ELISAs) and two previously developed DON-antibodies (Mab#1 and Mab#22) were tested. Cross-reactivity with NX-metabolites was not observed for any of the ELISA-kits nor Mab#22, whereas Mab#1 reacted moderately against NX-3 and NX-4 (cross-reactivity based on a molar basis of 14 and 30%, respectively). Modifications at position C-3 (3-acetyl-DON and DON-3-glucoside) led to moderate or high cross-reactivity with Mab#22 and the commercial ELISA-kits, whereas these compounds were not recognised by Mab#1. Similar to NX-metabolites, 15-acetyl-DON interacted only weakly with Mab#22 and the commercial ELISA-kits, but strongly with Mab#1. The results demonstrate the importance of proper antibody characterisation. If NX-metabolites prove to be widely distributed and reach significant levels, the development of specific antibodies targeting these novel metabolites might become necessary.

Abstract
BACKGROUND Pityriasis rubra pilaris (PRP) is a rare chronic inflammatory dermatosis with multifactorial aetiology. It is known that particular caspase recruitment domain family member 14 (CARD14) gene mutations are associated with familial PRP and certain forms of psoriasis. Additionally, few data are available about the role of CARD14 gene variants in sporadic PRP. The clinical picture is variable for the different types of PRP, therefore choosing the adequate treatment is often difficult, furthermore there are no specific guidelines for therapy. OBJECTIVE Our aim was to survey the efficacy of the applied therapies and to screen the CARD14 gene variants in our PRP patients. METHODS In this retrospective study, patients diagnosed with PRP between 2006 and 2016 at our clinic were involved. Besides the follow-up study of the treatments, the genetic analysis of CARD14 gene was performed. RESULTS We analysed 19 patients, among whom 17 were diagnosed with type I, one with type III, and one with type V PRP. The majority of the patients were successfully treated with acitretin in combination with systemic corticosteroids, and the remaining patients were treated with other systemic therapies with diverse effects. The genetic screening of CARD14 gene revealed two previously described mutations (rs114688446, rs117918077) and six polymorphisms (rs28674001, rs2066964, rs34367357, rs11653893, rs11652075, rs2289541). Ten of 19 patients carried different CARD14 genetic variants either alone or in combination. CONCLUSION Based on our experience, we propose that acitretin and an initial combination of short-term systemic corticosteroid therapy could be a successful treatment option for PRP. Although we identified several CARD14 variants in almost half of our cases, we did not find a correlation between the therapeutic response and the genetic background. Our data support the previous observation that CARD14 genetic variants are not specific to PRP, although they may indicate chronic inflammation.

Abstract
Leukaemia cutis is a relatively rare manifestation in chronic lymphocytic leukaemia, characterized by a diverse morphology of skin lesions. We report two patients who developed zosteriform skin symptoms; however, the histological analysis revealed leukaemia infiltration as the cause of their symptoms. Contrary to previous reports, varicella zoster virus DNA was detectable in the lesions. These findings suggest that varicella zoster virus plays an active role in the development of zosteriform leukaemia cutis.

Abstract
Gangliogliomas (WHO grade I) are rare tumors affecting the central nervous system and are most frequently observed in children. Next-generation sequencing of tumors is being utilized at an increasing rate in both research and clinical settings to characterize the genetic factors that drive tumorigenesis. Here, we report a rare BRAF somatic mutation (NM_004333.4:c.1794_1796dupTAC; p.Thr599dup) in the tumor genome from a pediatric patient in her late teens, who was initially diagnosed with low-grade ganglioglioma at age 13. This duplication of 3 nt introduces a second threonine residue at amino acid 599 of the BRAF protein. Based on previous studies, this variant is likely to increase kinase activity, similar to the well-characterized BRAF p.Val600Glu (V600E) pathogenic variant. In addition, although the p.T599dup somatic mutation has been documented rarely in human cancers, the variant has not been previously reported in ganglioglioma. The identification of this variant presents an opportunity to consider targeted therapy (e.g., BRAF inhibitor) for this patient.

Abstract
Allogeneic HCT is curative for SCN; however, a standard conditioning regimen or intensity has not been established. We describe a patient with SCN associated with c.1A>G (M1V) mutation in ELANE gene resulting in refractoriness to G-CSF, who received reduced-intensity HCT and developed secondary graft failure requiring a second myeloablative HCT. This case suggests that M1V mutation confers a poor G-CSF response and HCT using the best available donor is beneficial.

Abstract
BACKGROUND Despite universal screening that detects sickle cell trait (SCT) in infancy, only 16% of Americans with SCT know their status. To increase SCT status awareness, effective education for patients and their families is needed. The objective of this study was to assess caregivers' SCT knowledge before and after an in-person SCT education session. METHODS A trained educator provides in-person SCT education to caregivers of referred infants with SCT at Nationwide Children's Hospital. From August 2015 to July 2016, primarily English-speaking caregivers of infants with hemoglobin S-trait were recruited and completed a health literacy assessment and a SCT knowledge assessment (SCTKA) before and after receiving education. Caregivers repeated the SCTKA again after ≥6 months, if they could be contacted. RESULTS Thirty-eight (38.1%) percent of 113 caregivers had high SCTKA scores (≥75%) before education but 90.3% achieved high scores after education. Caregivers with low SCTKA scores after education had significantly lower health literacy (P = 0.029) and baseline SCTKA scores (P = 0.003) compared to those with higher scores after education. At ≥6 months, caregivers' scores were significantly higher (P = 0.014) than baseline, but only 73.3% scored ≥75%. CONCLUSION Our results suggest that caregivers' baseline SCT knowledge is low, improves with in-person education but may decline with time. Caregivers who do not achieve high SCT knowledge after education had lower health literacy and baseline knowledge. Future studies should determine if adapting in-person education to caregivers' health literacy and knowledge levels results in high and sustained SCT knowledge among all caregivers and more individuals who know their SCT status.

Abstract
Lipedema is a disproportional obesity featuring spontaneous or light pressure-induce pain and frequent hematoma formation due to even minor traumatic injuries. It is generally distinguished from general obesity primarily based on clinical hallmarks; however, this becomes difficult when appearing in a concomitant form (combination of obesity and lipedema). Our study group has recently demonstrated that lipedema-associated bruising is correlated with increased capillary fragility (CF) and also that CF could be significantly improved by complex decongestive physiotherapy (CDP). In this study, we measured CF in female subjects with lipedema (15) or non-complicated obesity (15) who were body mass index (BMI) and waist-to-hip ratio (WHR) matched. CF was evaluated with the vacuum suction method (VSM) using Parrot's angiosterrometer in both groups. Application of VSM resulted in a significantly higher number of petechiae in subjects with lipedema. Capillary fragility measurement appears to be a useful differential diagnostic tool between lipedema and obesity under these trial parameters.

Abstract
INTRODUCTION Prunus spinosa L. (blackthorn, sloe) is a com- mon species in the wild flora of Europe. Marmalade, syrup, and alcoholic beverages have been prepared from fruits. In folk medicine they'are used due to the astringent effect. However there are few studies on these indigenous fruits. According to the literature they contain tannins, anthocyanins, sugars, vitamin C etc. METHODS Our objective is to determine the antioxidant activity as related to their phenolic composition. For this purpose we prepared extracts using methanol, methanol-water (1: 1) and water. The antioxidant activity was determined by DPPH method and by photochemiluminescens (PCL) method. The total polyphenols, total anthocyanins and flavonoids were determined by colorimetric methods. Individual polyphenols were identified by a RP-HPLC-UVIVIS method. RESULTS The antioxidant activity decreased in the extracts as follows: methanol > methanol-water > water (IC₅₀= 1.33 mg/ml for DPPH; 11.94 μmol AAEIml for PCL > IC₅₀ = 1.87 mg/ml for DPPH; 10.35 μmol AAElml for PCL > IC₅₀ = 15.29 mg/ml for DPPH, 1.89 μmol AAElml for PCL) which is cor- related with the total polyphenol content (369 mg/100g > 244 mg1100g > 101 mg1100g) and total anthocyanin content (37.11 mg/100 g > 16.33 mg/100g > 7.76 mg/100g). The fla- vonoid content is similar in the three extracts (between 35.82 - 37.32 mg1100 g). The HPLC analysis shows high chloro- genic and neochlorogenic acid levels, followed by glycosides of quercetin. CONCLUSIONS Our results demonstrated that blackthorn fruits are a rich source of phenolic compounds, with anti- oxidant activity, which are best extracted with methanol or methanol-water.

Abstract
INTRODUCTION Individuals with Down syndrome (DS) have an increased risk of acute leukemia compared to a markedly decreased incidence of solid tumors. Medulloblastoma, the most common malignant brain tumor of childhood, is particularly rare in the DS population, with only one published case. As demonstrated in a mouse model, DS is associated with cerebellar hypoplasia and a decreased number of cerebellar granule neuron progenitor cells (CGNPs) in the external granule cell layer (EGL). Treatment of these mice with sonic hedgehog signaling pathway (Shh) agonists promote normalization of CGNPs and improved cognitive functioning. CASE REPORT We describe a 21-month-old male with DS and concurrent desmoplastic/nodular medulloblastoma (DNMB)-a tumor derived from Shh dysregulation and over-activation of CGNPs. Molecular profiling further classified the tumor into the new consensus SHH molecular subgroup. Additional testing revealed a de novo heterozygous germ line mutation in the PTCH1 gene encoding a tumor suppressor protein in the Shh pathway. DISCUSSION The developmental failure of CGNPs in DS patients offers a plausible explanation for the rarity of medulloblastoma in this population. Conversely, patients with PTCH1 germline mutations experience Shh overstimulation resulting in Gorlin (Nevoid Basal Cell Carcinoma) syndrome and an increased incidence of malignant transformation of CGNPs leading to medulloblastoma formation. This represents the first documented report of an individual with DS simultaneously carrying PTCH1 germline mutation. CONCLUSION We have observed a highly unusual circumstance in which the PTCH1 mutation appears to "trump" the effects of DS in causation of Shh-activated medulloblastoma.

Abstract
Next-generation sequencing (NGS) technology is increasingly utilized to identify therapeutic targets for patients with malignancy. This technology also has the capability to reveal the presence of constitutional genetic alterations, which may have significant implications for patients and their family members. Here we present the case of a 23 year old Caucasian patient with recurrent undifferentiated sarcoma who had NGS-based tumor analysis using an assay which simultaneously analyzed the entire coding sequence of 236 cancer-related genes (3769 exons) plus 47 introns from 19 genes often rearranged or altered in cancer. Pathogenic alterations were reported in tumor as the predicted protein alterations, BRCA2 “R645fs*15″ and MLH1 “E694*”. Because constitutional BRCA2 and MLH1 gene mutations are associated with Hereditary Breast Ovarian Cancer Syndrome (HBOCS) and Lynch syndrome respectively, sequence analysis of DNA isolated from peripheral blood was performed. The presence of the alterations, BRCA2 c.1929delG and MLH1 c.2080G>T, corresponding to the previously reported predicted protein alterations, were confirmed by Sanger sequencing in the constitutional DNA. An additional DNA finding was reported in this analysis, MLH1 c.2081A>C at the neighboring nucleotide. Further evaluation of the family revealed that all alterations were paternally inherited and the two MLH1 substitutions were in cis, more appropriately referred to as MLH1 c.2080_2081delGAinsTC, which is classified as a variant of uncertain significance. This case illustrates important considerations related to appropriate interpretation of NGS tumor results and follow-up of patients with potentially deleterious constitutional alterations.

Abstract
The 5, 10 methylenetetrahydrofolate reductase (MTHFR) enzyme is a catalyst in the folate metabolism pathway, the byproducts of which are involved in the remethylation of homocysteine to methionine. Methionine is a precursor for a major DNA methyl donor and is important for DNA methylation and gene regulation. Rare mutations in the MTHFR gene have been associated with autosomal recessive MTHFR deficiency leading to homocystinuria. In addition, two polymorphic variants in this gene (C677T and A1298C) have been implicated in a mild form of MTHFR deficiency associated with hyperhomocysteinemia. Mild to moderate hyperhomocysteinemia has been previously implicated as a risk factor for cardiovascular disease. Further, the presence of these variants, with and without mildly elevated levels of homocysteine, has been studied in relation to several multifactorial disorders including recurrent pregnancy loss, neural tube defects and congenital anomalies, cancer, and neurodevelopmental disorders. Given this wide spectrum of purported clinical implications and the prevalence of these polymorphisms, genetic counselors may encounter questions regarding the significance of MTHFR polymorphisms in a variety of settings. Here we present a brief background of the MTHFR polymorphisms, review of the literature regarding clinical considerations, and discussion of relevant genetic counseling aspects through case vignettes. Educational resources for patients and providers are also included.

Abstract
Background The purpose of this study was to investigate the consistency of working length control between hand instrumentation in comparison to engine driven Mtwo nickel-titanium rotary files. Material and Methods Forty extracted maxillary molars were selected and divided onto two parallel groups. The working lengths of the mesiobuccal root canals were estimated. The teeth were fixed in a phantom head. The root canal preparation was carried out group 1 (n=20) with hand K-files, (VDW, Munich, Germany) and group 2 (n=20) with Mtwo instruments (VDW, Munich, Germany). Vestibulo-oral and mesio-distal directional x-ray images were taken before the preparation with #10 K-file, inserted into the mesiobuccal root canal to the working length, and after preparation with #25, #30 and #40 files. Working lenght changes were detected with measurements between the radiological apex and the instrument tips. Results In the Mtwo group a difference in the working competency (p<0.05) could be noticed only in the vestibulo-oral direction from #10 to #40 file. The hand instrument group showed a significant difference in working length competency for each larger file size (p<0.05) (ANOVA). Regression analysis in the hand instrumentation group indicated a working length decrease with a mean of 0,2 mm after each consecutive file size (p<0.01). Conclusions The outcome of our trial indicated a high consistency in working length control for root canal preparation under simulated clinical condition using Mtwo rotary files. Mtwo NiTi rotary file did therefore proved to be more accurate in comparison to the conventional hand instrumentation. Key words:Working length, Mtwo, nickel-titanium, hand preparation, engine driven preparation.

Abstract
The interaction of CeO2-supported Rh, Co and bimetallic Rh-Co nanoparticles, which are active catalysts in hydrogen production via steam reforming of ethanol, a process related to renewable energy generation, was studied by X-ray diffraction (XRD), high resolution electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS) and low energy ion scattering (LEIS). Furthermore, diffuse reflectance infrared spectroscopy (DRIFTS) of adsorbed CO as a probe molecule was used to characterize the morphology of metal particles. At small loadings (0.1%), Rh is in a much dispersed state on ceria, while at higher contents (1-5%), Rh forms 2-8 nm particles. Between 473-673 K pronounced oxygen transfer from ceria to Rh is observed and at 773 K significant agglomeration of Rh occurs. On reduced ceria, XPS indicates a possible electron transfer from Rh to ceria. The formation of smaller ceria crystallites upon loading with Co was concluded from XRD and HRTEM; for 10% Co, the CeO2 particle size decreased from 27.6 to 10.7 nm. A strong dissolution of Co into ceria and a certain extent of encapsulation by ceria were deduced by XRD, XPS and LEIS. In the bimetallic system, the presence of Rh enhances the reduction of cobalt and ceria. During thermal treatments, reoxidation of Co occurs, and Rh agglomeration as well as oxygen migration from ceria to Rh are hindered in the presence of cobalt.

Abstract
From a dermatological aspect, it posed a considerable challenge the skin-limited form of mastocytosis, urticaria pigmentosa and indolent systemic mastocytosis (ISM) with cutaneous lesions. Despite the favourable prognosis, lifelong dermatological control is needed, during which the average symptomatic therapy does not always seem adequate. We report here the case of a female ISM patient with recurrent cutaneous symptoms that impaired her quality of life, with a follow-up time of 27 years. During this long follow-up period, the cutaneous lesions could be controlled by antihistamines, leukotriene antagonists, glucocorticoids, local immunosuppressants or local UV radiation for only relatively short periods. Imatinib mesylate was, therefore, introduced in an attempt to control the cutaneous lesions. Tyrosine kinase inhibition is an unusual dermatological therapeutic option. This case illustrates that imatinib mesylate was a good choice with which to achieve a reduction of the skin lesions in this KIT D816V mutation-negative disease: it led to a temporary appreciable improvement of the patient's quality of life.

Abstract
Schizophrenic patients have Theory of Mind (ToM) deficits even during remission, but it is yet unknown whether this could be influenced. We examined the neural correlates of irony understanding in schizophrenic patients, as an indicator of ToM capacity, and evaluated how linguistic help inserted into the context phase could affect irony comprehension. Schizophrenic patients in remission and healthy controls were subjected to event-related functional MRI scanning while performing irony, 'irony with linguistic help', and control tasks. Patients understood irony significantly worse than healthy controls. The patients showed stronger brain activity in the parietal and frontal areas in the early phase of irony task, however the healthy controls exhibited higher activation in frontal, temporal and parietal regions in the latter phase of the irony task. Interestingly the linguistic help not only improved the patients' ToM performance, but it also evoked similar activation pattern to healthy controls.

Abstract
Computerized treatment planning is routinely used in cranio-maxillofacial applications. For these therapeutic applications, it is of critical importance to have a precise model of the structures in question. Improved imaging techniques and advances in software engineering have moved three-dimensional (3D) computer models from the research and development area into routine clinical application. The importance of high-resolution source imaging is well understood by surgeons. The influence of image processing is poorly understood in the surgical community and we hypothesize that this may be a source of significant error. We evaluated the workflow for creating a virtual model using computed tomography data, and the impact that image processing decisions have on final virtual model accuracy. We chose to create a model of the dental surface since it is one of the most complex structures in the area. Individual image processing steps are explained and the magnitudes of their influence on model quality are demonstrated and compared. This study demonstrates that inappropriate image processing can introduce errors of similar magnitude as the use of inadequate source data. Finally, the study shows that errors caused by inappropriate image processing amplify the inaccuracies of low-resolution source imagery and eliminate the benefits of high-resolution source imaging.

Abstract
The correlation between activity concentrations of some natural radionuclides ((238)U, (226)Ra, (232)Th, (40)K) measured in soil and in sediment taken from the Danube River and nearby irrigation channels was studied. The soil samples were collected from the northern part of Serbia and the sediment from the Serbian part of the Danube River and from the surrounding irrigation channels. The correlation between (238)U and other natural radionuclides in irrigation channel sediments was not as good as in the Danube. One of the possible explanations for this weak correlation can be the different chemical dynamics of (238)U in the irrigation channel sediment or changes of the (238)U activity concentration in irrigation channel sediment due to some human activities. The evaluation of ratios of activity concentrations of some natural radionuclides could be a more sensitive method for the determination of contaminant, rather than the straightforward analysis of activity concentrations.
