Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft-tissue sarcomas with a poor survival rate, presenting either sporadically or in the context of neurofibromatosis type 1 (NF1). The histological diagnosis of MPNSTs can be challenging, with different tumors exhibiting great histological and marker expression overlap. This heterogeneity could be partly responsible for the observed disparity in treatment response due to the inherent diversity of the preclinical models used. For several years, our group has been generating a large patient-derived orthotopic xenograft (PDOX) MPNST platform for identifying new precision medicine treatments. Herein, we describe the expansion of this platform using six primary tumors clinically diagnosed as MPNSTs, from which we obtained six additional PDOX mouse models and three cell lines, thus generating three pairs of in vitro-in vivo models. We extensively characterized these tumors and derived preclinical models, including genomic, epigenomic, and histological analyses. Tumors were reclassified after these analyses: three remained as MPNSTs (two being classic MPNSTs), one was a melanoma, another was a neurotrophic tyrosine receptor kinase (NTRK)-rearranged spindle cell neoplasm, and, finally, the last was an unclassifiable tumor bearing neurofibromin-2 (NF2) inactivation, a neuroblastoma RAS viral oncogene homolog (NRAS) oncogenic mutation, and a SWI/SNF-related matrix-associated actin-dependent regulator of chromatin (SMARCA4) heterozygous truncated variant. New cell lines and PDOXs faithfully recapitulated histology, marker expression, and genomic characteristics of the primary tumors. The diversity in tumor identity and their specific associated genomic alterations impacted treatment responses obtained when we used the new cell lines for testing compounds against known altered pathways in MPNSTs. In summary, we present here an extension of our MPNST precision medicine platform, with new PDOXs and cell lines, including tumor entities confounded as MPNSTs in a real clinical scenario. This platform may constitute a useful tool for obtaining correct preclinical information to guide MPNST clinical trials.

Abstract
Cutaneous neurofibromas (cNFs) are benign Schwann cell (SC) tumors arising from subepidermal glia. Individuals with neurofibromatosis type 1 (NF1) may develop thousands of cNFs, which greatly affect their quality of life. cNF growth is driven by the proliferation of NF1-/- SCs and their interaction with the NF1+/- microenvironment. We analyzed the crosstalk between human cNF-derived SCs and fibroblasts (FBs), identifying an expression signature specific to the SC-FB interaction. We validated the secretion of proteins involved in immune cell migration, suggesting a role of SC-FB crosstalk in immune cell recruitment. The signature also captured components of developmental signaling pathways, including the cAMP elevator G protein-coupled receptor 68 (GPR68). Activation of Gpr68 by ogerin in combination with the MEK inhibitor (MEKi) selumetinib reduced viability and induced differentiation and death of human cNF-derived primary SCs, a result corroborated using an induced pluripotent stem cell-derived 3D neurofibromasphere model. Similar results were obtained using other Gpr68 activators or cAMP analogs/adenylyl cyclase activators in combination with selumetinib. Interestingly, whereas primary SC cultures restarted their proliferation after treatment with selumetinib alone was stopped, the combination of ogerin-selumetinib elicited a permanent halt on SC expansion that persisted after drug removal. These results indicate that unbalancing the Ras and cAMP pathways by combining MEKi and cAMP elevators could be used as a potential treatment for cNFs.

Abstract
Neurofibromatosis type 1 (NF1) is caused by a nonfunctional copy of the NF1 tumor suppressor gene that predisposes patients to the development of cutaneous neurofibromas (cNFs), the skin tumor that is the hallmark of this condition. Innumerable benign cNFs, each appearing by an independent somatic inactivation of the remaining functional NF1 allele, form in nearly all patients with NF1. One of the limitations in developing a treatment for cNFs is an incomplete understanding of the underlying pathophysiology and limitations in experimental modeling. Recent advances in preclinical in vitro and in vivo modeling have substantially enhanced our understanding of cNF biology and created unprecedented opportunities for therapeutic discovery. We discuss the current state of cNF preclinical in vitro and in vivo model systems, including two- and three-dimensional cell cultures, organoids, genetically engineered mice, patient-derived xenografts, and porcine models. We highlight the models' relationship to human cNFs and how they can be used to gain insight into cNF development and therapeutic discovery.

Abstract
Neurofibromatosis type 1 is one of the most common genetic disorders of the nervous system and predisposes patients to develop benign and malignant tumors. Cutaneous neurofibromas (cNFs) are NF1-associated benign tumors that affect nearly 100% of patients with NF1. cNFs dramatically reduce patients' QOL owing to their unaesthetic appearance, physical discomfort, and corresponding psychological burden. There is currently no effective drug therapy option, and treatment is restricted to surgical removal. One of the greatest hurdles for cNF management is the variability of clinical expressivity in NF1, resulting in intrapatient and interpatient cNF tumor burden heterogeneity, that is, the variability in the presentation and evolution of these tumors. There is growing evidence that a wide array of factors are involved in the regulation of cNF heterogeneity. Understanding the mechanisms underlying this heterogeneity of cNF at the molecular, cellular, and environmental levels can facilitate the development of innovative and personalized treatment regimens.

Abstract
Neurofibromas are benign peripheral nervous system tumors associated with neurofibromatosis type 1, which originate from NF1(-/-) Schwann cell precursors. We describe a protocol to generate neurofibromaspheres by differentiating NF1(-/-) Schwann cells from induced pluripotent stem cells and combining them with neurofibroma primary fibroblasts. We also describe the development of neurofibroma-like tumors when neurofibromaspheres are engrafted in the sciatic nerve of nude mice. This model constitutes a versatile platform for drug screening and the study of neurofibroma biology. For complete details on the use and execution of this protocol, please refer to Mazuelas et al. (2022).1.

Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) are soft-tissue sarcomas of the peripheral nervous system that develop either sporadically or in the context of neurofibromatosis type 1 (NF1). MPNST diagnosis can be challenging and treatment outcomes are poor. We present here a resource consisting of the genomic characterization of 9 widely used human MPNST cell lines for their use in translational research. NF1-related cell lines recapitulated primary MPNST copy number profiles, exhibited NF1, CDKN2A, and SUZ12/EED tumor suppressor gene (TSG) inactivation, and presented no gain-of-function mutations. In contrast, sporadic cell lines collectively displayed different TSG inactivation patterns and presented kinase-activating mutations, fusion genes, altered mutational frequencies and COSMIC signatures, and different methylome-based classifications. Cell lines re-classified as melanomas and other sarcomas exhibited a different drug-treatment response. Deep genomic analysis, methylome-based classification, and cell-identity marker expression, challenged the identity of common MPNST cell lines, opening an opportunity to revise MPNST differential diagnosis.

Abstract
BACKGROUND Moderate-severe atopic dermatitis (AD) has a significant impact on patients' lives, with many requiring systemic treatment to manage symptoms (e.g., pruritus). Several drugs are used off-label to treat AD. This study describes sociodemographic/clinical characteristics, treatment patterns, health resource use (HRU) and costs in adults with AD who initiated systemic treatment or phototherapy in routine practice. METHODS This retrospective observational study of electronic medical records in the BIG-PAC database identified adults with prior diagnosis of AD (ICD-9: 691.8 or 692.9) starting oral corticosteroids, immunosuppressants, biologics or phototherapy between 01/01/2012 and 31/12/2016. Patients were followed for 3 years from treatment initiation, up to 31/12/2019. Data on patient characteristics, treatment patterns, HRU and costs were analyzed descriptively. RESULTS Patients (N=1995) had a mean age of 60 years, 64% were female, with a mean time of 23 years since diagnosis (84% were ≥18 years at AD onset). Main comorbidities were anxiety (38%), arterial hypertension (36%) and dyslipidemia (35%). Most patients used oral corticosteroids as first systemic (84%; median duration 29 days) and immunosuppressants in 13% of patients (median duration 117 days, 5% cyclosporine and 4% methotrexate). Half of patients required a second line systemic and 12% a third line. The use of immunosuppressants and biologics increased with treatment lines. About 13% of patients received systemic treatments continuously over the 3-year follow-up. The average 3-year per patient cost was 3835 euros, with an average annual cost of 1278 euros. CONCLUSIONS Results suggest a high comorbidity and economic burden in this real-world adult population with AD, and the need for systemic treatments indicated for use in AD.

Abstract
BACKGROUND Moderate-severe atopic dermatitis (AD) has a significant impact on patients' lives, with many requiring systemic treatment to manage symptoms (e.g., pruritus). Several drugs are used off-label to treat AD. This study describes sociodemographic/clinical characteristics, treatment patterns, health resource use (HRU) and costs in adults with AD who initiated systemic treatment or phototherapy in routine practice. METHODS This retrospective observational study of electronic medical records in the BIG-PAC database identified adults with prior diagnosis of AD (ICD-9: 691.8 or 692.9) starting oral corticosteroids, immunosuppressants, biologics or phototherapy between 01/01/2012 and 31/12/2016.

Abstract
NF2-related schwannomatosis (NF2-related SWN) is an autosomal dominant condition caused by loss of function variants in the NF2 gene, which codes for the protein Merlin and is characterized by the development of multiple tumors of the nervous system. The clinical presentation of the disease is variable and related to the type of the inherited germline variant. Here, we tested if phosphorodiamidate morpholino oligomers (PMOs) could be used to correct the splice signaling caused by variants at ±13 within the intron-exon boundary region and showed that the PMOs designed for these variants do not constitute a therapeutic approach. Furthermore, we evaluated the use of PMOs to decrease the severity of the effects of NF2 truncating variants with the aim of generating milder hypomorphic isoforms in vitro through the induction of the in-frame deletion of the exon-carrying variant. We were able to specifically induce the skipping of exons 4, 8, and 11 maintaining the NF2 gene reading frame at cDNA level. Only the skipping of exon 11 produced a hypomorphic Merlin (Merlin-e11), which is able to partially rescue the observed phenotype in primary fibroblast cultures from NF2-related SWN patients, being encouraging for the treatment of patients harboring truncating variants located in exon 11.

Abstract
Malignant peripheral nerve sheath tumors (MPNST) are soft-tissue sarcomas that are the leading cause of mortality in patients with Neurofibromatosis type 1 (NF1). Single chemotherapeutic agents have shown response rates ranging from 18% to 44% in clinical trials, so there is still a high medical need to identify chemotherapeutic combination treatments that improve clinical prognosis and outcome. We screened a collection of compounds from the NCATS Mechanism Interrogation PlatE (MIPE) library in three MPNST cell lines, using cell viability and apoptosis assays. We then tested whether compounds that were active as single agents were synergistic when screened as pairwise combinations. Synergistic combinations in vitro were further evaluated in patient-derived orthotopic xenograft/orthoxenograft (PDOX) athymic models engrafted with primary MPNST matching with their paired primary-derived cell line where synergism was observed. The high-throughput screening identified 21 synergistic combinations, from which four exhibited potent synergies in a broad panel of MPNST cell lines. One of the combinations, MK-1775 with Doxorubicin, significantly reduced tumor growth in a sporadic PDOX model (MPNST-SP-01; sevenfold) and in an NF1-PDOX model (MPNST-NF1-09; fourfold) and presented greater effects in TP53 mutated MPNST cell lines. The other three combinations, all involving Panobinostat (combined with NVP-BGT226, Torin 2, or Carfilzomib), did not reduce the tumor volume in vivo at noncytotoxic doses. Our results support the utility of our screening platform of in vitro and in vivo models to explore new therapeutic approaches for MPNSTs and identified that combination MK-1775 with Doxorubicin could be a good pharmacologic option for the treatment of these tumors.

Abstract
Abstract
Takotsubo syndrome (TTS) is a cardiomyopathy induced by physical and/or emotional stress, characterised by transient changes of the regional motion generally extending beyond the territory distribution of one single coronary vessel. The classic form of TTS presents, in 43.7% of cases, with ST segment elevation and in about 80% with cardiac apical ballooning. In 1.5% of TTS cases, however, regional changes in motion are observed which may mimic an acute coronary syndrome. We describe the case of a 77–year–old woman with hypertension and hypercholesterolemia. The patient came to the ER due to polytrauma secondary to an accidental fall. During hospitalisation, the patient complained of a sudden onset of a retrosternal aching chest pain radiating to the back and right shoulder, associated with neurovegetative symptoms. An electrocardiogram showed a normofrequent sinus rhythm and T–negative waves in the infero–lateral region. Upon cardiology consultation, a transthoracic echocardiogram was performed showing a left ventricle with akinesia of the middle and apical segments of the inferolateral wall with compensatory hyperkinesis of the other segments. When an acute coronary syndrome was suspected, urgent coronary imaging was performed, showing coronary arteries without significant stenosis, while ventriculography confirmed the alterations in ventricular motion. Blood chemistry tests showed a phasic increase in myocardial necrosis enzymes and, in particular, in HS troponin values (max value 2714 ng/L). Therapy with an ace–inhibitor and a beta blocker was introduced; seriate echocardiographic controls showed a progressive normalisation of the alterations in motion. A TTS diagnosis was therefore made, according to InterTAK 2018 diagnostic criteria. This case is of particular interest as it is a prime example of a rare variant of TTS: the clinical presentation, the ECG alterations and the regional akinesia may lead to a clinical suspicion of ACS. A good knowledge of the TTS, including the focal variant, enables the cardiologist to make a correct diagnosis and to initiate suitable therapy.

Abstract
Abstract
Arrhythmogenic cardiomyopathy (ACM) is characterised by myocardial structural alterations with fibro–adipose replacement/infiltration, most frequently affecting the right ventricle. Malignant arrhythmias represent the most dangerous clinical manifestation.
We describe the case of a 38–year–old man who came to the Emergency Room of our hospital due to polytrauma. Following the unexpected ECG finding of signs of necrosis in the infero–lateral area and negative T waves in the antero–lateral area, a cardiological examination was performed. The patient, a smoker, had non–contributory family and personal history of cardiovascular diseases and sudden cardiac death. However, he reported several unspecified episodes of “absence seizures”. The transthoracic echocardiogram showed mild reduction in global left ventricular systolic function (EF 45–50%) due to regional changes in motion extending beyond the territory distribution of one single coronary vessel. Holter–ECG showed a Sustained Ventricular Tachycardia (SVT) symptomatic for syncope. A coronary angiography was therefore performed, which excluded any significant coronary stenosis and a cardiac MRI revealed the presence of fibro–adipose replacement of the left ventricle and, to a lesser extent, of the right side of the interventricular septum. Medical therapy with Bisoprolol, Ramipril, Spironolactone was initiated and an ICD was implanted as secondary prevention. No endomyocardial biopsy was carried out due to the high risk of the procedure; genetic testing proved to be negative. A diagnosis of borderline arrhythmogenic cardiomyopathy was therefore made. This case is of special interest as ACM with predominant left ventricular involvement (LDAC) is a rare cardiomyopathy. Diagnosis is made difficult by the presence of phenocopies and by the fact that the diagnostic criteria in use mostly focus on the forms with predominantly right–sided involvement. In the case of suspicious ECG changes, SVT or resuscitated cardiac death with imaging compatible with cardiomyopathy, it is important to raise the diagnostic suspicion of LDAC.

Abstract
Abstract
Aortic dissection (AD) is the tearing of the tunica intima of the aortic wall with creation of a false lumen. Type–A AD, in which the intimal flaps originates in the aortic tract proximal to the left subclavian artery, is a surgical emergency because – if left untreated – it has mortality rates as high as 1–2% every hour, from the onset of symptoms. Certain collagenopathies, such as Marfan Syndrome, are a predisposing condition for AD. We describe the case of a 25–year–old man with Marfanoid habitus who came to the Emergency Room of our facility, with acute pulmonary oedema. He had been complaining about thoraco–abdominal pain, bloody mucus and worsening dyspnoea since the week before. Upon cardiology consultation, a transthoracic echocardiogram showed an aneurysm of the aortic root (70 mm) and the ascending aorta (90 mm), with dissection flap extended beneath the aortic valvular plane, with torrential aortic valve insufficiency and eccentric jet, a left ventricle severely dilated and a severe systolic dysfunction (EF 25%). On urgent CT angiography the dissection flap was observed to extend cranially to the right common carotid artery and caudally to the renal arteries. The patient then underwent cardiac surgery to replace the aortic valve with a mechanical prosthesis and the ascending aorta as per the Bentall procedure and to replace the aortic arch with reimplantation and debranching of the supra–aortic trunks. Four months after discharge, the patient presented again due to sustained ventricular tachycardia (SVT) which was interrupted by electric cardioversion. On this occasion, an ICD implant was indicated as a secondary prevention measure. After one month, recurrence of SVT was observed, which was successfully treated by the implanted ICD, and therefore indication was given for an electrophysiologic study and subsequent transcatheter radiofrequency ablation of the ventricular arrhythmia. The case presented is of particular interest as it highlights the crucial role of a rapid echocardiographic assessment focussed on making a diagnosis and directing treatment, despite a misleading clinical picture due to duration and atypicality of symptoms. It should also be stressed that an overall assessment of the patient, based on habitus and age, plays a major role in establishing a suspected diagnosis and guiding the patient towards the most appropriate treatment.

Abstract
Background Neurofibromatosis type 2 (NF2) is a genetic disease characterized by the appearance of multiple tumours in the nervous system. Cutaneous lesions are common and may provide useful diagnostic and prognostic information, but they have not been widely studied. Objectives To characterize cutaneous lesions in a Spanish cohort of patients with NF2 and investigate associations with clinical and genetic severity. Methods We studied the clinical and histologic characteristics of cutaneous lesions in 49 patients with NF2 and analysed correlations with phenotype‐ and genotype‐based severity scores. We collected information on the presence/absence of cutaneous lesions, location, age at onset, type of lesion, and histologic features. We also studied level of systemic involvement and genetic mutations involved. Results Forty‐nine patients (31 women [63.3%] and 18 men [36.7%]) were analysed, and 33 (67.3%) had cutaneous lesions presumed to be schwannomas. According to their clinical form, they were distributed as follows: 24 patients (48%) had deep tumours, 21 (42%) had plaque‐like lesions, and 3 (6%) had superficial tumours. Histologic examination from 27 lesions analysed out 23 patients showed classic schwannoma or hybrid schwannoma‐neurofibroma features in the 8 deep tumours biopsied and plexiform schwannoma features in the 17 plaque‐like lesions and the 2 superficial tumours analysed. Early onset (first 2 decades of life) was reported by all patients with plaques and superficial tumours. In our cohort, 100% of the patients with plaque‐like lesions and superficial tumours with microscopic features of plexiform schwannoma were in the 2 groups with the most severe clinical phenotypes, and 82.6% of them were in the 3 most severe genotype‐based classes. Conclusions and Relevance Cutaneous lesions, specially plexiform schwannomas, are common in NF2, and they usually appear at an early age providing useful diagnostic and prognostic information. These tumours are part of the spectrum of cutaneous manifestations in this disease. Although its diagnostic and prognostic value has been pointed out, there are few studies focussed on their analysis.

Abstract
Introduction Lung transplant recipients are at increased risk of SARS-CoV2 infection due to immunosuppression and their management has yet to be standardized. We report a case of prolonged COVID-19 infection in a lung recipient acquired after transplant during the hospital stay. Case Report A 52-year-old lady with interstitial disease associated to systemic sclerosis underwent bilateral lung transplantation on 04/10/21. Donors and recipient microbiological tests for SARS-CoV2 were negative on molecular swabs performed before transplantation (04/07 and 04/10). Transplantation was uneventful and the recipient was extubated the subsequent day. Twelve days later, a surveillance molecular nose-pharyngeal swab was positive for SARS-CoV2. The positivity for subgenomic analysis revealed productive infection. At first monitoring biopsy, multiple foci of diffuse alveolar damage, significant cytopathic features of pneumocytes, microthrombi of capillaries, and extensive edema were highly suggestive of COVID-19 pneumonia. High viral load was also detected in lung biopsy by RT-PCR. She presented mild respiratory symptoms (cough with low oxygen supplementation) and the CT scan revealed an area of consolidation at the right lower lobe. Monoclonal antibody therapy (Bamlanivimab and Etesevimab) associated with remdesevir was started, IV immunoglobulins were administered while mycophenolate mofetil was discontinued. The patient was closely monitored until the nose-pharyngeal swab turned negative two months after the first positivity associated with a significant clinical improvement. At the last follow-up, five months after transplantation, she had good pulmonary function, no immunological disorders and no signs related to long COVID-19. Summary This is a case of prolonged hospital acquired COVID-19 related pneumonia in a lung recipient. Immunocompromized patients present a longer viral clearance. In this fragile population a strict clinical, radiological and histopathological monitoring associated with encouragement of vaccination are mandatory.

Abstract
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder caused by pathogenic variants in NF1 Recently, NF1 testing has been included as a clinical criterion for NF1 diagnosis. Additionally, preconception genetic counselling in patients with NF1 focuses on a 50% risk of transmitting the familial variant as the risk of having a sporadic NF1 is considered the same as the general population. METHODS 829 individuals, 583 NF1 sporadic cases and 246 patients with NF1 with documented family history, underwent genetic testing for NF1. Genotyping and segregation analysis of NF1 familial variants was determined by microsatellite analysis and NF1 sequencing. RESULTS The mutational analysis of NF1 in 154 families with two or more affected cases studied showed the co-occurrence of two different NF1 germline pathogenic variants in four families. The estimated mutation rate in those families was 3.89×10-3, 20 times higher than the NF1 mutation rate (~2×10-4) (p=0.0008). Furthermore, the co-occurrence of two different NF1 germline pathogenic variants in these families was 1:39, 60 times the frequency of sporadic NF1 (1:2500) (p=0.003). In all cases, the de novo NF1 pathogenic variant was present in a descendant of an affected male. In two cases, variants were detected in the inherited paternal wild-type allele. CONCLUSIONS Our results, together with previous cases reported, suggest that the offspring of male patients with NF1 could have an increased risk of experiencing de novo NF1 pathogenic variants. This observation, if confirmed in additional cohorts, could have relevant implications for NF1 genetic counselling, family planning and NF1 genetic testing.

Abstract
Constitutional LZTR1 or SMARCB1 pathogenic variants (PVs) have been found in ∼86% of familial and ∼40% of sporadic schwannomatosis cases. Hence, we performed massively parallel sequencing of the entire LZTR1, SMARCB1, and NF2 genomic loci in 35 individuals with schwannomas negative for constitutional first-hit PVs in the LZTR1/SMARCB1/NF2 coding sequences; however, with 22q deletion and/or a different NF2 PV in each tumor, including six cases with only one tumor available. Furthermore, we verified whether any other LZTR1/SMARCB1/NF2 (likely) PVs could be found in 16 cases carrying a SMARCB1 constitutional variant in the 3'-untranslated region (3'-UTR) c.*17C>T, c.*70C>T, or c.*82C>T. As no additional variants were found, functional studies were performed to clarify the effect of these 3'-UTR variants on the transcript. The 3'-UTR variants c.*17C>T and c.*82C>T showed pathogenicity by negatively affecting the SMARCB1 transcript level. Two novel deep intronic SMARCB1 variants, c.500+883T>G and c.500+887G>A, resulting in out-of-frame missplicing of intron 4, were identified in two unrelated individuals. Further resequencing of the entire repeat-masked genomics sequences of chromosome 22q in individuals negative for PVs in the SMARCB1/LZTR1/NF2 coding- and noncoding regions revealed five potential schwannomatosis-predisposing candidate genes, that is, MYO18B, NEFH, SGSM1, SGSM3, and SBF1, pending further verification.

Abstract
BACKGROUND Neurofibromatosis type 2 (NF2) is an autosomal dominant disorder characterised by the development of multiple schwannomas, especially on vestibular nerves, and meningiomas. The UK NF2 Genetic Severity Score (GSS) is useful to predict the progression of the disease from germline NF2 pathogenic variants, which allows the clinical follow-up and the genetic counselling offered to affected families to be optimised. METHODS 52 Spanish patients were classified using the GSS, and patients' clinical severity was measured and compared between GSS groups. The GSS was reviewed with the addition of phenotype quantification, genetic variant classification and functional assays of Merlin and its downstream pathways. Principal component analysis and regression models were used to evaluate the differences between severity and the effect of NF2 germline variants. RESULTS The GSS was validated in the Spanish NF2 cohort. However, for 25% of mosaic patients and patients harbouring variants associated with mild and moderate phenotypes, it did not perform as well for predicting clinical outcomes as it did for pathogenic variants associated with severe phenotypes. We studied the possibility of modifying the mutation classification in the GSS by adding the impact of pathogenic variants on the function of Merlin in 27 cases. This revision helped to reduce variability within NF2 mutation classes and moderately enhanced the correlation between patient phenotype and the different prognosis parameters analysed (R2=0.38 vs R2=0.32, p>0001). CONCLUSIONS We validated the UK NF2 GSS in a Spanish NF2 cohort, despite the significant phenotypic variability identified within it. The revision of the GSS, named Functional Genetic Severity Score, could add value for the classification of mosaic patients and patients showing mild and moderate phenotypes once it has been validated in other cohorts.

Abstract
Malignant peripheral nerve sheath tumors (MPNST) are aggressive soft tissue sarcomas with poor prognosis, developing either sporadically or in persons with neurofibromatosis type 1 (NF1). Loss of CDKN2A/B is an important early event in MPNST progression. However, many reported MPNSTs exhibit partial or no inactivation of CDKN2A/B, raising the question of whether there is more than one molecular path for MPNST initiation. We present here a comprehensive genomic analysis of MPNST cell lines and tumors to explore in depth the status of CDKN2A. After accounting for CDKN2A deletions and point mutations, we uncovered a previously unnoticed high frequency of chromosomal translocations involving CDKN2A in both MPNST cell lines and primary tumors. Most identified translocation breakpoints were validated by PCR amplification and Sanger sequencing. Many breakpoints clustered in an intronic 500 bp hotspot region adjacent to CDKN2A exon 2. We demonstrate the bi-allelic inactivation of CDKN2A in all tumors (n = 15) and cell lines (n = 8) analyzed, supporting a single molecular path for MPNST initiation in both sporadic and NF1-related MPNSTs. This general CDKN2A inactivation in MPNSTs has implications for MPNST diagnostics and treatment. Our findings might be relevant for other tumor types with high frequencies of CDKN2A inactivation.

Abstract
Germline copy-number variants (CNVs) are relevant mutations for multiple genetics fields, such as the study of hereditary diseases. However, available benchmarks show that all next-generation sequencing (NGS) CNV calling tools produce false positives. We developed CNVfilteR, an R package that uses the single nucleotide variant calls usually obtained in germline NGS pipelines to identify those false positives. The package can detect both false deletions and false duplications. We evaluated CNVfilteR performance on callsets generated by 13 CNV calling tools on 3 whole-genome sequencing and 541 panel samples, showing a decrease of up to 44.8% in false positives and consistent F1-score increase. Using CNVfilteR to detect false-positive calls can improve the overall performance of existing CNV calling pipelines. AVAILABILITY CNVfilteR is released under Artistic-2.0 License.

Abstract
Cancer cells can develop a strong addiction to discrete molecular regulators, which control the aberrant gene expression programs that drive and maintain the cancer phenotype. Here, we report the identification of the RNA-binding protein HuR/ELAVL1 as a central oncogenic driver for malignant peripheral nerve sheath tumors (MPNSTs), which are highly aggressive sarcomas that originate from cells of the Schwann cell lineage. HuR was found to be highly elevated and bound to a multitude of cancer-associated transcripts in human MPNST samples. Accordingly, genetic and pharmacological inhibition of HuR had potent cytostatic and cytotoxic effects on tumor growth, and strongly suppressed metastatic capacity in vivo. Importantly, we linked the profound tumorigenic function of HuR to its ability to simultaneously regulate multiple essential oncogenic pathways in MPNST cells, including the Wnt/β-catenin, YAP/TAZ, RB/E2F, and BET pathways, which converge on key transcriptional networks. Given the exceptional dependency of MPNST cells on HuR for survival, proliferation, and dissemination, we propose that HuR represents a promising therapeutic target for MPNST treatment.

Abstract
OBJECTIVE Studies have shown that prenatal exome sequencing (PES) improves diagnostic yield in cases of fetal structural malformation. We have retrospectively analysed PES cases from two of the largest fetal medicine centres in the UK to determine the impact of results on management of a pregnancy. DESIGN A retrospective review of clinical case notes. SETTING Two tertiary fetal medicine centres. POPULATION Pregnancies with fetal structural abnormalities referred to clinical genetics via a multidisciplinary team. METHODS We retrospectively reviewed the notes of all patients who had undergone PES. DNA samples were obtained via chorionic villus sampling or amniocentesis. Variants were filtered using patient-specific panels and interpreted using American College of Medical Genetics guidelines. RESULTS A molecular diagnosis was made in 42% (18/43) ongoing pregnancies; of this group, there was a significant management implication in 44% (8/18). A positive result contributed to the decision to terminate a pregnancy in 16% (7/43) of cases. A negative result had a significant impact on management in two cases by affirming the decision to continue pregnancy. CONCLUSIONS We demonstrate that the results of PES can inform pregnancy management. Challenges include variant interpretation with limited phenotype information. These results emphasise the importance of the MDT and collecting phenotype and variant data. As this testing is soon to be widely available, we should look to move beyond diagnostic yield as a measure of the value of PES. TWEETABLE ABSTRACT Prenatal exome sequencing can aid decision-making in pregnancy management; review ahead of routine implementation in NHS.

Abstract
INTRODUCTION Germline CNVs are important contributors to hereditary cancer. In genetic diagnostics, multiplex ligation-dependent probe amplification (MLPA) is commonly used to identify them. However, MLPA is time-consuming and expensive if applied to many genes, hence many routine laboratories test only a subset of genes of interest. METHODS AND RESULTS We evaluated a next-generation sequencing (NGS)-based CNV detection tool (DECoN) as first-tier screening to decrease costs and turnaround time and expand CNV analysis to all genes of clinical interest in our diagnostics routine. We used DECoN in a retrospective cohort of 1860 patients where a limited number of genes were previously analysed by MLPA, and in a prospective cohort of 2041 patients, without MLPA analysis. In the retrospective cohort, 6 new CNVs were identified and confirmed by MLPA. In the prospective cohort, 19 CNVs were identified and confirmed by MLPA, 8 of these would have been lost in our previous MLPA-restricted detection strategy. Also, the number of genes tested by MLPA across all samples decreased by 93.0% in the prospective cohort. CONCLUSION Including an in silico germline NGS CNV detection tool improved our genetic diagnostics strategy in hereditary cancer, both increasing the number of CNVs detected and reducing turnaround time and costs.

Abstract
Background: The aim of this study was to test the feasibility and utility of developing
patient-derived orthotopic xenograft (PDOX) models for patients with
malignant peripheral nerve sheath tumors (MPNSTs) to aid therapeutic
interventions in real time. Patient & Methods: A sporadic relapsed MPNST developed in a 14-year-old boy was engrafted in
mice, generating a PDOX model for use in co-clinical trials after informed
consent. SNP-array and exome sequencing was performed on the relapsed tumor.
Genomics, drug availability, and published literature guided PDOX
treatments. Results: A MPNST PDOX model was generated and expanded. Analysis of the patient’s
relapsed tumor revealed mutations in the MAPK1, EED, and
CDK2NA/B genes. First, the PDOX model was treated with
the same therapeutic regimen as received by the patient (everolimus and
trametinib); after observing partial response, tumors were left to regrow.
Regrown tumors were treated based on mutations (palbociclib and JQ1), drug
availability, and published literature (nab-paclitaxel; bevacizumab;
sorafenib plus doxorubicin; and gemcitabine plus docetaxel). The patient had
a lung metastatic relapse and was treated according to PDOX results, first
with nab-paclitaxel, second with sorafenib plus doxorubicin after
progression, although a complete response was not achieved and multiple
metastasectomies were performed. The patient is currently disease free
46 months after first relapse. Conclusion: Our results indicate the feasibility of generating MPNST-PDOX and genomic
characterization to guide treatment in real time. Although the treatment
responses observed in our model did not fully recapitulate the patient’s
response, this pilot study identify key aspects to improve our co-clinical
testing approach in real time.

Abstract
Recent optomechanical experiments have observed nonclassical properties in macroscopic mechanical oscillators. A key indicator of such properties is the asymmetry in the strength of the motional sidebands produced in the probe electromagnetic field, which is originated by the noncommutativity between the oscillator ladder operators. Here we extend the analysis to a squeezed state of an oscillator embedded in an optical cavity, produced by the parametric effect originated by a suitable combination of optical fields. The motional sidebands assume a peculiar shape, related to the modified system dynamics, with asymmetric features revealing and quantifying the quantum component of the squeezed oscillator motion.

Abstract
Background Malignant peripheral nerve sheath tumor (MPNST) constitutes the leading cause of neurofibromatosis type 1–related mortality. MPNSTs contain highly rearranged hyperploid genomes and exhibit a high division rate and aggressiveness. We have studied in vitro whether the mitotic kinesins KIF11, KIF15, and KIF23 have a functional role in maintaining MPNST cell survival and can represent potential therapeutic vulnerabilities. Methods We studied the expression of kinesin mRNAs and proteins in tumors and cell lines and used several in vitro functional assays to analyze the impact of kinesin genetic suppression (KIF15, KIF23) and drug inhibition (KIF11) in MPNST cells. We also performed in vitro combined treatments targeting KIF11 together with other described MPNST targets. Results The studied kinesins were overexpressed in MPNST samples. KIF15 and KIF23 were required for the survival of MPNST cell lines, which were also more sensitive than benign control fibroblasts to the KIF11 inhibitors ispinesib and ARRY-520. Co-targeting KIF11 and BRD4 with ARRY-520 and JQ1 reduced MPNST cell viability, synergistically killing a much higher proportion of MPNST cells than control fibroblasts. In addition, genetic suppression of KIF15 conferred an increased sensitivity to KIF11 inhibitors alone or in combination with JQ1. Conclusions The mitotic spindle kinesins KIF11 and KIF15 and the cytokinetic kinesin KIF23 play a clear role in maintaining MPNST cell survival and may represent potential therapeutic vulnerabilities. Although further in vivo evidences are still mandatory, we propose a simultaneous suppression of KIF11, KIF15, and BRD4 as a potential therapy for MPNSTs.

Abstract
Permafrost degradation, rock-glacier thawing, and glacier retreat are influencing surface water quality at high elevations. However, there is a lack of knowledge on the dominant geochemical reactions occurring in different cryospheric conditions and how these reactions change during the ice-free season. In the Col d'Olen area (LTER site, NW Italian Alps), four ponds with similar sizes, located in basins with different cryospheric features (glacier, permafrost, rock glacier, none of these), are present in a geographically limited area. All ponds were sampled weekly in 2015 and partially in 2014. Major ions, selected trace elements, and biotic parameters (dissolved organic carbon-DOC, fluorescence index-FI, and nitrate) are examined to evidence the effect of different cryospheric features on water characteristics. Where cryospheric conditions occur chemical weathering is more intensive, with strong seasonal increase of major ions. Sulphide oxidation dominates in glacier and permafrost lying on acid rocks, probably driven by enhanced weathering of freshly exposed rocks in subglacial environment and recently deglaciated areas, and active layer thickness increase. Differently, carbonation dominates for the rock glacier lying on ultramafic rocks. There, high Ni concentrations originate from dissolution of Mg-bearing rocks in the landform. In all settings, pH neutralisation occurs because of the presence of secondary carbonate lithology and ultramafic rocks. Nitrate highest concentrations and changes occur in cryospheric settings while DOC and FI do not show strong differences and seasonal variations. The establishment of more frequent monitoring for water quality in high-elevated surface waters is necessary to provide greater statistical power to detect changes on longer time scales.

Abstract
Importance Neurofibromatosis type 2 (NF2) is a devastating genetic condition characterized by the development of multiple tumors of the nervous system. An early diagnosis of individuals with NF2 would facilitate treatment and reduction of disease impact because most severe effects of the disease do not usually develop before adolescence. Little attention has traditionally been paid to dermatological signs in NF2. However, skin plaques are commonly seen in patients with NF2, normally appearing either at birth or early childhood, providing an opportunity for early NF2 detection and testing. Objective To determine the clinical utility of skin plaque identification and characterization in children for reaching an early diagnosis of patients with NF2 and to evaluate their molecular pathogenesis and their use in the genetic diagnostics of NF2. Design, Setting, and Participants Diagnostic test study by the histological and genetic characterization of skin plaques from patients with NF2. Patients were 7 individuals with NF2 or clinical suspicion of NF2 treated at the Spanish Reference Center on Phakomatoses. Main Outcomes and Measures Histological evaluation of all skin plaques was performed. Fresh skin plaques were cultured to obtain Schwann cells and the NF2 gene was genetically analyzed. For all 7 patients, NF2 clinical history was reviewed. Results In all 7 patients (4 male and 3 female), all skin plaques analyzed were histologically characterized as plexiform schwannomas. Genetic analysis of primary Schwann cell cultures derived from them allowed the identification of a constitutional and a somatic NF2 mutation. Genetic testing allowed the early diagnosis of NF2 in a child only exhibiting the presence of skin plaques. Most of the patients with NF2 analyzed had an early presentation of skin plaques and a severe NF2 phenotype. Conclusions and Relevance This work emphasizes the clinical utility of a careful dermatological inspection and the correct identification of skin plaques in children for an early diagnosis of NF2. We show for the first time that Schwann cells derived from skin plaque plexiform schwannomas bear the double inactivation of the NF2 gene and thus constitute an excellent source of tissue for genetic testing, especially in the context of mosaicism.

Abstract
Organized and hosted by the Children's Tumor Foundation (CTF), the Neurofibromatosis (NF) conference is the premier annual gathering for clinicians and researchers interested in neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis (SWN). The 2016 edition constituted a blend of clinical and basic aspects of NF research that helped in clarifying different advances in the field. The incorporation of next generation sequencing is changing the way genetic diagnostics is performed for NF and related disorders, providing solutions to problems like genetic heterogeneity, overlapping clinical manifestations, or the presence of mosaicism. The transformation from plexiform neurofibroma (PNF) to malignant peripheral nerve sheath tumor (MPNST) is being clarified, along with new management and treatments for benign and premalignant tumors. Promising new cellular and in vivo models for understanding the musculoskeletal abnormalities in NF1, the development of NF2 or SWN associated schwannomas, and clarifying the cells that give rise to NF1-associated optic pathway glioma were presented. The interaction of neurofibromin and SPRED1 was described comprehensively, providing functional insight that will help in the interpretation of pathogenicity of certain missense variants identified in NF1 and Legius syndrome patients. Novel promising imaging techniques are being developed, as well as new integrative and holistic management models for patients that take into account psychological, social, and biological factors. Importantly, new therapeutic approaches for schwannomas, meningiomas, ependymomas, PNF, and MPNST are being pursued. This report highlights the major advances that were presented at the 2016 CTF NF conference.

Abstract
Motivation Data visualization is a crucial tool for data exploration, analysis and interpretation. For the visualization of genomic data there lacks a tool to create customizable non-circular plots of whole genomes from any species. Results We have developed karyoploteR, an R/Bioconductor package to create linear chromosomal representations of any genome with genomic annotations and experimental data plotted along them. Plot creation process is inspired in R base graphics, with a main function creating karyoplots with no data and multiple additional functions, including custom functions written by the end-user, adding data and other graphical elements. This approach allows the creation of highly customizable plots from arbitrary data with complete freedom on data positioning and representation. Availability and implementation karyoploteR is released under Artistic-2.0 License.

Abstract
Plexiform neurofibromas (PNFs) are benign peripheral nerve sheath tumors involving large nerves present in 30%-50% Neurofibromatosis type 1 (NF1) patients. Atypical neurofibromas (ANF) are distinct nodular lesions with atypical features on histology that arise from PNFs. The risk and timeline of malignant transformation in ANF is difficult to assess. A recent NIH workshop has stratified ANFs and separated a subgroup with multiple atypical features and higher risk of malignant transformation termed atypical neurofibromatous neoplasms with uncertain biological potential (ANNUBP). We performed an analysis of intratumor heterogeneity on eight PNFs to link histological and genomic findings. Tumors were homogeneous although histological and molecular heterogeneity was identified. All tumors were 2n, almost mutation-free and had a clonal NF1(-/-) origin. Two ANFs from the same patient showed atypical features on histology and deletions of CDKN2A/B. One of the ANFs exhibited different areas in which the degree of histological atypia correlated with the heterozygous or homozygous loss of the CDKN2A/B loci. CDKN2A/B deletions in different areas originated independently. Results may indicate that loss of a single CDKN2A/B copy in NF1(-/-) cells is sufficient to start ANF development and that total inactivation of both copies of CDKN2A/B is necessary to form an ANNUBP.

Abstract
Surgery for esophageal cancer is a highly stressful and painful procedure, and a significant amount of analgesics may be required to eliminate perioperative pain and blunt the stress response to surgery. Proper management of postoperative pain has invariably been shown to reduce the incidence of postoperative complications and accelerate recovery. Neuraxial analgesic techniques after major thoracic and upper abdominal surgery have long been established to reduce respiratory, cardiovascular, metabolic, inflammatory, and neurohormonal complications.The aim of this review is to evaluate and discuss the relevant clinical benefits and outcome, as well as the possibilities and limits of thoracic epidural anesthesia/analgesia (TEA) in the setting of esophageal resections. A comprehensive search of original articles was conducted investigating relevant literature on MEDLINE, Cochrane reviews, Google Scholar, PubMed, and EMBASE from 1985 to July2017. The relationship between TEA and important endpoints such as the quality of postoperative pain control, postoperative respiratory complications, surgical stress-induced immunosuppression, the overall postoperative morbidity, length of hospital stay, and major outcomes has been explored and reported. TEA has proven to enable patients to mobilize faster, cooperate comfortably with respiratory physiotherapists and achieve satisfactory postoperative lung functions more rapidly. The superior analgesia provided by thoracic epidurals compared to that from parenteral opioids may decrease the incidence of ineffective cough, atelectasis and pulmonary infections, while the associated sympathetic block has been shown to enhance bowel blood flow, prevent reductions in gastric conduit perfusion, and reduce the duration of ileus. Epidural anesthesia/analgesia is still commonly used for major 'open' esophageal surgery, and the recognized advantages in this setting are soundly established, in particular as regards the early recovery from anesthesia, the quality of postoperative pain control, and the significantly shorter duration of postoperative mechanical ventilation. However, this technique requires specific technical skills for an optimal conduction and is not devoid of risks, complications, and failures.

Abstract
BACKGROUND T-type calcium channels have been shown to play an important role in the initiation and maintenance of neuropathic pain and represent a promising therapeutic target for new analgesic treatments. Ethosuximide (ETX), an anticonvulsant and a T-type channel blocker has shown analgesic effect in several chronic pain models but has not yet been evaluated in patients with neuropathic pain. METHODS This proof-of-concept, multicentre, double-blind, controlled and randomized trial compared the efficacy and safety of ETX (given as add-on therapy) to an inactive control (IC) in 114 patients with non-diabetic peripheral neuropathic pain. After a 7-day run-in period, eligible patients aged over 18 years were randomly assigned (1:1) to ETX or IC for 6 weeks. The primary outcome was the difference between groups in the pain intensity (% of change from the baseline to end of treatment) assessed in the intention-to-treat population. This study is registered with EudraCT (2013-004801-26) and ClinicalTrials.gov (NCT02100046). RESULTS The study was stopped during the interim analysis due to the high number of adverse events in the active treatment group. ETX failed to reduce total pain and showed a poor tolerance in comparison to IC. In the per-protocol analysis, ETX significantly reduced pain intensity by 15.6% (95% CI -25.8; -5.4) from baseline compared to IC (-7.8%, 95% CI -14.3; -1.3; p = 0.033), but this result must be interpreted with caution because of a small subgroup of patients. CONCLUSION Ethosuximide did not reduce the severity of neuropathic pain and induces, at the doses used, many adverse events. SIGNIFICANCE This article shows that ETX is not effective to treat neuropathic pain. Nevertheless, per-protocol analysis suggests a possible analgesic effect of ETX. Thus, our work adds significant knowledge to preclinical and clinical data on the benefits of T-type calcium channel inhibition for the treatment of neuropathic pain.

Abstract
Microtubules (MTs), polymers of alpha/beta-tubulin heterodimers, are involved in crucial functions in eukaryotic cells. MTs physiology can be influenced by a variety of post-translational modifications (PTMs), including tyrosination, detyrosination, delta 2 modification, acetylation, polyglutamylation, polyglycylation. In mammalian oocytes, MTs are essential for meiosis, regulating the formation of meiotic spindle and chromosomes movements. Considering that the patterns of tubulin PTMs (tyrosination, detyrosination, acetylation, polyglutamylation and delta 2 modification) have not been investigated in ovine oocytes, this study has been designed to investigate their presence and quantification in in vitro matured (IVM) adult and prepubertal ovine oocytes. Oocytes from adult and lamb Sarda ewes, regularly slaughtered at the local abattoir, were in vitro matured, fixed, and processed by indirect immunofluorescence and confocal microscopy analyses at metaphase II stage. Our results revealed a well detectable signal for total, tyrosinated and acetylated α-tubulin in meiotic spindle of both sheep and lamb oocytes. On the other hand, no immunopositivity were appreciable for detyrosinated, polyglutamylated, and delta 2 tubulin in meiotic spindle of both sheep and lamb oocytes. As regard the tyrosinated and the acetylated α-tubulin PTMs, through the quantification of the fluorescence intensity, we did not find significant differences in their expression in meiotic spindle of sheep, while in lamb the acetylated tubulin levels were predominant in comparison with tyrosinated. Our results in addition to investigating for the first time the different tubulin PTMs in the spindle organization of ovine oocytes, showed a different microtubule pattern between adult and prepubertal oocytes. The microtubule cytoskeleton survey may thus suggest further cues to better understand skill-related problems in in the acquisition of oocyte competence.

Abstract
The extraordinary sensitivity of the output field of an optical cavity to small quantum-scale displacements has led to breakthroughs such as the first detection of gravitational waves and of the motions of quantum ground-state cooled mechanical oscillators. While heterodyne detection of the output optical field of an optomechanical system exhibits asymmetries which provide a key signature that the mechanical oscillator has attained the quantum regime, important quantum correlations are lost. In turn, homodyning can detect quantum squeezing in an optical quadrature but loses the important sideband asymmetries. Here we introduce and experimentally demonstrate a new technique, subjecting the autocorrelators of the output current to filter functions, which restores the lost heterodyne correlations (whether classical or quantum), drastically augmenting the useful information accessible. The filtering even adjusts for moderate errors in the locking phase of the local oscillator. Hence we demonstrate the single-shot measurement of hundreds of different field quadratures allowing the rapid imaging of detailed features from a simple heterodyne trace. We also obtain a spectrum of hybrid homodyne-heterodyne character, with motional sidebands of combined amplitudes comparable to homodyne. Although investigated here in a thermal regime, the method's robustness and generality represents a promising new approach to sensing of quantum-scale displacements.

Abstract
This study determined the influence of a short-term glucogenic nutritional treatment on circulating concentrations of glucose, insulin, insulin-like growth factor 1 (IGF-1), nonesterified fatty acids (NEFA), and urea, and on their correspondent levels in follicular fluid (FF) collected 12 h after the end of the treatment. After estrous synchronization with intravaginal progestagen-impregnated sponges, 20 Sarda ewes were randomly allocated into two experimental groups (GLU and WAT) and, from day 7 to day 10 (day 0 = day of sponge removal), the GLU group was gavaged with a glycogenic mixture, whereas the WAT group was gavaged with water (control group). Follicular development was stimulated by FSH administration from day 8 to 10. At day 11, ovaries were collected and follicular fluid processed. Plasma changes were assessed from day 6 to 11. In GLU group, circulating concentration of glucose (P < 0.0001), insulin (P < 0.0001), and IGF-1 (P < 0.01) rose significantly, whereas NEFA and urea concentrations decreased (P < 0.0001), as compared with controls. In particular, in FF the higher glucose concentrations found in GLU ewes compared with controls (P < 0.0001) were not accompanied by any increase in insulin and IGF-1 concentrations. NEFA (P < 0.0001) and urea (P < 0.0001) were lower in FF of GLU than WAT group, although NEFA clearance in the ovary proved to be less efficient than at the systemic level. No significant difference between groups was found in FF concentrations of pregnancy-associated plasma protein A (a protease regulating the levels of free IGF-1 in follicles), glutathione, and in its total antioxidant capacity. These results suggest that glycogenic mixture administration creates a suitable follicular microenvironment for the conception period in dairy ewes.

Abstract
OBJECTIVES Pain is a common experience, both physical and emotional. However we often feel powerless with our patients suffering pain. This paper aims to give a new heuristic and psychological understanding of pain. METHODOLOGY According to new theories, recent researches as well as different points of view, we form an analogy between pain and emotion. Throughout historical considerations pain has always been perceived through theories and beliefs, changing its definition. This is also the case for emotion. Could they be two ways of expressing a single phenomenon? RESULTS First, we must clarify the definition of emotion. In past, emotion was considered as a multiple-conditioned notion. To be considered as an emotion the pain had to fill numerous features, which differ according to the scientific opinions. The emotion may be considered as a physical expression or perceived only as the consequences of a real emotion, i.e., the subjective feeling. We propose as a way of thinking that emotion brings together these two concepts. We support a flexible vision of emotion. To investigate the field of the emotion different mental steps may be thought of: we should conceive of the emotion as a stimulus, as an emotional evaluation and as a tendency to action, which becomes an emotional response. These steps are colored by subjective feelings. It can be summarized in three levels: the situation decoding (1), the response organization (2) and the effectiveness of the response (3). Second pain can be considered as a complex notion involving personal and subjective feelings. We can use multidimensional patterns and consider emotion with its multiple features: the generating mechanisms, the pain perception, the pain behavior and the environment. Each stage can be divided in different ways. Hence pain treatment could be approached as an emotional treatment. Indeed, we can make a link between generating mechanisms and emotion situation decoding, between pain perception and emotion situation decoding and response organization, between pain behavior and environment and emotion response effectiveness and consequences. A heuristic analogy can be formed enriching therapeutic possibilities. First, emotion and pain could be considered as a unique phenomenon that can be expressed in different ways. We can let aside the opposition between psychological and physiological: these are two different levels of a same phenomenon. This point of view can be helpful to treat pain disorders because the skills to manage emotion disorders are well known.
