Abstract
PURPOSE Family-based treatment (FBT) has contributed significantly to the treatment of anorexia nervosa (AN) in young people (YP). However, parents are concerned that FBT and the active role of parents in the task of refeeding may have a negative impact on family relations. The aim of the review is to assess whether families engaged in FBT for AN are more or less impacted in their family wellbeing and caregiver burden, compared to families with a YP diagnosed with AN, who are not undergoing treatment with FBT. METHOD Computerized searches across six databases complemented by a manual search resulted in 30 papers being included in the scoping review. RESULTS The review identified 19 longitudinal studies on change in family wellbeing in families in FBT-like treatments, and 11 longitudinal studies on change in family wellbeing in treatment where parents are not in charge of refeeding. Only three randomized controlled studies directly compare FBT to treatment without parent-led refeeding. CONCLUSION The available research suggests no difference between intervention types regarding impact on family wellbeing. Approximately half of the studies find improvements in family wellbeing in both treatment with and without parent-led refeeding, while the same proportion find neither improvement nor deterioration. As parents play a pivotal role in FBT, there is a need for good quality studies to elucidate the impact of FBT on family wellbeing. Level of evidence Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Abstract
Background Despite advances in the etiology of anorexia nervosa (AN), a large subgroup of individuals does not profit optimally from treatment. Perfectionism has been found to be a risk factor predicting the onset, severity, and duration of AN episodes. To date, perfectionism has been studied predominantly by the use of self-report questionnaires, a useful approach that may, however, be impacted by demand characteristics, or other distortions of introspective or metacognitive access. Methods Here we circumvent these problems via a behavioral paradigm in which participants perform a modified Go/NoGo task, whilst self-evaluating their performance. We compared a group of 33 adolescent females during their first episode of AN (age = 16.0) with 29 female controls (age = 16.2), and 23 adolescent girls recovered from AN (age = 18.3) with 23 female controls (age = 18.5). The controls were closely matched by intelligence quotient and age to the two clinical groups. Results First-episode AN and control participants performed equally well on the task (reaction time and errors of commission), whereas the recovered group displayed significantly faster reaction times but incurred the same error rate. Despite performing at least as good as and predominantly better than control groups, both clinical groups evaluated their performances more negatively than controls. Conclusion We offer a novel behavioral method for measuring perfectionism independent of self-report, and we provide tentative evidence that this behavioral manifestation of perfectionism is evident during first-episode AN and persists even after recovery.

Abstract
OBJECTIVE The objective of this study was to investigate the predictive value of sex, age, body mass index (BMI), Eating Disorder Examination (EDE) score, social risk factors, and psychiatric comorbidities for hospitalization and hospitalization duration among children and adolescents suffering from eating disorders. METHOD This prospective cohort study involved 522 consecutive patients who had been referred to a specialized eating disorder unit between January 1, 2009 and December 31, 2015; participants were followed up until August 1, 2016 by medical records. We used regression analyses to evaluate the prognostic value of sex, age, BMI, EDE, eating disorder diagnoses, social risk factors, and psychiatric comorbidities concerning inpatient hospitalization and hospitalization duration. RESULTS We found that younger age, higher EDE global score, lower BMI percentile, anorexia nervosa, a higher number of social risk factors, and the presence of diagnosed self-harm increased the odds of being hospitalized, while being female and having a comorbid autism spectrum condition increased the duration of hospitalization. No other psychiatric comorbidity was found to significantly predict hospitalization or duration of hospitalization. DISCUSSION The odds of being hospitalized were predicted by the severity of anorexia nervosa and indicators of social risk factors in the family, whereas the duration of hospitalization was predicted by having a comorbid autism spectrum condition, indicating a difference between the factors affecting the risk of hospitalization and the factors affecting the duration of hospitalization. This calls for further exploration of tailored treatments for eating disorders. PUBLIC SIGNIFICANCE STATEMENT This study finds that hospitalization for an eating disorder is predicted by the severity of the illness, self-harm, and social risk factors. Duration of hospitalization is predicted by having a comorbid autism spectrum condition. These findings indicate that the treatment of eating disorders may require different treatment approaches depending on the presentation of the individual patient to reduce both the need for hospitalization and the length of inpatient stay.

Abstract
The aim of this randomized clinical trial was to evaluate the impact of all-trans retinoic acid (ATRA) in combination with non-intensive chemotherapy in older unfit patients (> 60 years) with newly diagnosed NPM1-mutated acute myeloid leukemia. Patients were randomized (1:1) to low-dose chemotherapy with or without open-label ATRA 45 mg/m2, days 8-28; the dose of ATRA was reduced to 45 mg/m2, days 8-10 and 15 mg/m2, days 11-28 after 75 patients due to toxicity. Up to 6 cycles of cytarabine 20 mg/day s.c., bid, days 1-7 and etoposide 100 mg/day, p.o. or i.v., days 1-3 with (ATRA) or without ATRA (CONTROL) were intended. The primary endpoint was overall survival (OS). Between May 2011 and September 2016, 144 patients (median age, 77 years; range, 64-92 years) were randomized (72, CONTROL; 72, ATRA). Baseline characteristics were balanced between the two study arms. The median number of treatment cycles was 2 in ATRA and 2.5 in CONTROL. OS was significantly shorter in the ATRA compared to the CONTROL arm (p = 0.023; median OS: 5 months versus 9.2 months, 2-years OS rate: 7% versus 10%, respectively). Rates of CR/CRi were not different between treatment arms; infections were more common in ATRA beyond treatment cycle one. The addition of ATRA to low-dose cytarabine plus etoposide in an older, unfit patient population was not beneficial, but rather led to an inferior outcome.The clinical trial is registered at clinicaltrialsregister.eu (EudraCT Number: 2010-023409-37, first posted 14/12/2010).

Abstract
OBJECTIVE Autism is more prevalent among persons with Restrictive type eating disorders (R-ED) compared to the general population and is associated with poorer outcomes across treatment modalities. Knowledge is sparse with regard to whether poorer outcomes are also associated with Family-based treatment (FBT), which is recommended as the first choice of treatment for young persons (YPs) with R-ED. This case series compares outcome between groups with and without autism in a large consecutive series of YPs with R-ED treated with FBT. METHOD In an earlier described consecutive series of 157 YPs with R-ED treated with FBT, we compared the outcomes of the subgroup with (N = 16) and without (N = 141) comorbid autism. Primary ICD-10 diagnoses were typical (50.0) or atypical anorexia nervosa (AN) (F50.1), the latter implying a condition as typical AN but with a failure to meet one of the diagnostic criteria. Autism diagnoses were clinically assigned. The outcomes were receiving intensified care, weight normalisation and overall successful treatment. RESULTS 10.2% (N = 16) of the sample had autism. 2.5% (N = 4) had autism diagnosed prior to the Eating Disorder (ED), and an additional 7.7% (N = 12) were diagnosed with autism during ED treatment. Significantly more YPs with autism (50%, N = 8) compared with YPs without autism (16%, N = 23) received intensified care (day programme or inpatient treatment) during their treatment. No significant difference between groups regarding neither weight normalisation nor successful ending of the treatment were found. CONCLUSION This small sample of YPs with autism suggests that comparable proportions of YPs with and without autism may restore normal weight and end the treatment successfully within 12 months. However, more YPs with comorbid autism needed more intensive treatment, indicating that outpatient treatment delivery may not be sufficient to bring about desired change in this patient group. Findings need confirmation in a larger sample with a systematic screening for autism.

Abstract
Anorexia nervosa (AN) is a disabling, costly and potentially deadly illness. Treatment failure and relapse are common after completing treatment, and a substantial proportion of patients develop severe and enduring AN. The time from AN debut to the treatment initiation is normally unreasonably long. Over the past 20 years there has been empirical support for the efficacy of several treatments for AN. Moreover, outpatient treatment with family-based therapy or individual psychotherapy is associated with good outcomes for a substantial proportion of patients. Early intervention improves outcomes and should be a priority for all patients. Outpatient treatment is usually the best format for early intervention, and it has been demonstrated that even patients with severe or extreme AN can be treated as outpatients if they are medically stable. Inpatient care is more disruptive, more costly, and usually has a longer waiting list than does outpatient care. The decision as to whether to proceed with outpatient treatment or to transfer the patient for inpatient therapy may be difficult. The core aim of this opinion review is to provide the knowledge base needed for performing safe outpatient treatment of AN. The scientific essentials for outpatient treatment are described, including how to assess and manage the medical risks of AN and how to decide when transition to inpatient care is indicated. The following aspects are discussed: early intervention, outpatient treatment of AN, including outpatient psychotherapy for severe and extreme AN, how to determine when outpatient treatment is safe, and when transfer to inpatient healthcare is indicated. Emerging treatments, ethical issues and outstanding research questions are also addressed.

Abstract
The Animated Triangles Task (AT) is commonly used to measure Theory of Mind (ToM). AT can be scored by clinicians based on participants’ verbal responses (AT-verbal) or using a multiple-choice paradigm (AT-MCQ). This study aimed to evaluate the validity of the less time-consuming AT-MCQ. To do this, we examined agreement and correlations between the AT-MCQ and the original AT-verbal scores in 1546 adolescents from a population-based sample. As a supplementary analysis of known-groups validity, we examined if AT-MCQ was as sensitive as AT-verbal in detecting ToM-limitations in 54 adolescents with autism spectrum disorder (ASD), using register-data. The agreement between AT-verbal and AT-MCQ varied markedly across test items. Scores on the two scoring methods were weakly correlated. Both scoring methods weakly detected differences between adolescents with and without ASD in this population-based sample. Most participants had appropriate responses on both AT-MCQ and AT-verbal, which yielded overall acceptable agreement. However, the feasibility of using either scoring methods to measure ToM-limitations in adolescents from the general population is questionable.

Abstract
BACKGROUND Family-based treatment (FBT) has demonstrated efficacy for anorexia nervosa (AN) in youth in randomized, controlled trials. It is important to assess if it shows a similar effectiveness when implemented in standard care. AIM To evaluate outcomes of FBT for restrictive-type eating disorders, delivered as standard care in a public mental health service. Outcomes are remission, frequency of hospital admissions and day-patient treatment, and frequency of other adaptations within 12 months from commencement of treatment. Second, to compare the collaborative clinical decisions of successful treatment in standard care made by family therapist at the end of treatment, with more objective definitions of recovery. METHODS The design is a prospective, uncontrolled study of a consecutive series of patients with restrictive-type eating disorders, treated with FBT in a specialty unit at the Child and Adolescent Mental Health Centre in the Capital Region of Denmark. RESULTS FBT was successfully completed within 12 months by 57% of participants, and 47% completed with 20 sessions or fewer. Weight restoration was achieved by 75% within 12 months, and 46% achieved both normalisation of body weight and behavioural symptoms of AN within 12 months. A total of 20% needed intensified treatment. All aspects of remission were often not present simultaneously, and the collaborative clinical decisions of successful treatment only partly aligned with other parameters of remission. CONCLUSION FBT showed good results when implemented as standard care, and it can be adapted to the specifics of local service organisation without compromising effectiveness.

Abstract
OBJECTIVE Studies have used the Autism Diagnostic Observation Schedule (the ADOS-2) in individuals with anorexia nervosa (AN), but the patterns of scores have not been assessed. We examined which subset of the ADOS-2 items best discriminate individuals with AN from healthy controls (HC), and assessed the potential clustering of AN participants based on different profiles of the ADOS-2 item scores. METHOD We combined datasets from two previous studies, and (a) compared mean ranks between young AN participants (N = 118) and HC (N = 42), (ii) replicated the item selection procedure of the existing ADOS-2 algorithm to assess sensitivity of items in the AN group, and (c) applied a two-step clustering analysis in the AN group (N = 149). RESULTS AN participants displayed significantly higher mean ranks than HC participants in five of 32 items. All five items are part of the existing ADOS-2 algorithm. We found two clusters of AN participants; one representing normal social behaviour, comprising 68% of the individuals with AN, and one representing less efficient social behaviour, comprising 32% of individuals with AN. CONCLUSIONS The items comprising the social affective cluster of the existing ADOS-2 algorithm are well suited to assess difficulties with social functioning in individuals with AN.

Abstract
Chronic myeloid leukemia (CML)-study IV was designed to explore whether treatment with imatinib (IM) at 400 mg/day (n=400) could be optimized by doubling the dose (n=420), adding interferon (IFN) (n=430) or cytarabine (n=158) or using IM after IFN-failure (n=128). From July 2002 to March 2012, 1551 newly diagnosed patients in chronic phase were randomized into a 5-arm study. The study was powered to detect a survival difference of 5% at 5 years. After a median observation time of 9.5 years, 10-year overall survival was 82%, 10-year progression-free survival was 80% and 10-year relative survival was 92%. Survival between IM400 mg and any experimental arm was not different. In a multivariate analysis, risk group, major-route chromosomal aberrations, comorbidities, smoking and treatment center (academic vs other) influenced survival significantly, but not any form of treatment optimization. Patients reaching the molecular response milestones at 3, 6 and 12 months had a significant survival advantage. For responders, monotherapy with IM400 mg provides a close to normal life expectancy independent of the time to response. Survival is more determined by patients' and disease factors than by initial treatment selection. Although improvements are also needed for refractory disease, more life-time can currently be gained by carefully addressing non-CML determinants of survival.

Abstract
Introduction Olfaction may be related to food restriction and weight loss. However, reports regarding olfactory function in individuals with anorexia nervosa (AN) have been inconclusive. Objective Characterize olfactory sensitivity and identification in female adolescents and young adults with first-episode AN and young females recovered from AN. Methods We used the Sniffin’ Sticks Odor Threshold Test and Odor Identification Test to assess 43 participants with first-episode AN, 27 recovered participants, and 39 control participants. Participants completed the Importance of Olfaction questionnaire, the Beck Youth Inventory and the Eating Disorder Inventory. We also conducted a psychiatric diagnostic interview and the Autism Diagnostic Observation Schedule with participants. Results Both clinical groups showed heightened olfactory sensitivity. After excluding participants with depression, participants with first-episode AN identified more odors than recovered participants. Conclusion Heightened olfactory sensitivity in AN may be independent of clinical status, whereas only individuals with current AN and without depression show more accurate odor identification.

Abstract
PURPOSE A subgroup of individuals with anorexia nervosa (AN) displays social difficulties; however, it is not clear if individuals with comorbid autism spectrum disorders account for these difficulties. METHODS We compared social function using the Autism Diagnostic Observation Schedule in 43 young females with first-episode AN who did not have comorbid autism spectrum disorder, 28 individuals recovered from adolescent-onset AN, and 41 healthy comparison individuals (age range 14-22 years). We measured adaptive behavior with the Vineland-II parent questionnaire, and aspects of social cognition with psychological tests, such as the Reading-the-Mind-in-the-Eyes test, Profile of Nonverbal Sensitivity short version, The Awareness of Social Inference Test, Animated Triangles, and the CANTAB Affective Go/No-go task. RESULTS Participants with first-episode AN and those recovered from AN displayed difficulties in social function, which were not associated with body mass index or other state factors of the disorder in those with first-episode AN. Mood problems and anxiety were not associated with these difficulties. Parents rated participants with first-episode AN lower than recovered and control participants on the Socialization Domain of Vineland-II. Finally, only participants recovered from AN demonstrated deficits in specific domains of social cognition: perceiving nonverbal bodily gesture and vocal prosody. CONCLUSIONS Young females with first-episode AN and those recovered from AN displayed impairments in social function, which may represent more stable traits of the disorder. Only participants recovered from AN demonstrated deficits in social cognition.

Abstract
BACKGROUND Young individuals with anorexia nervosa (AN) or recovered from AN display impairments of social function. To date, however, it is not clear whether they differ from controls with respect to neurocognitive performance and whether those functions contribute to the compromised social function observed in individuals with AN. METHODS We included 43 young females with first-episode AN, 28 individuals recovered from adolescent-onset AN, and 41 control individuals (14-22 yr), all without comorbid autism spectrum disorder. We compared the performance of participants across groups in seven neurocognitive functions relevant to social functioning: set-shifting, local processing, processing speed, working memory, sustained attention, verbal memory, and verbal abstraction. Further, we tested the association between neurocognitive function and social function, measured by Autism Diagnostic Observation Schedule (ADOS), with an ordinal logistic regression model. RESULTS First, participants did not differ on any neurocognitive function across groups. Second, only the neurocognitive function "verbal memory" was significantly associated with social function. Higher performance in verbal memory was associated with lower odds of impaired social function. Diagnostic group remained a significant factor, but the absence of an interaction between group and neurocognitive performance indicated that the association between verbal memory and social function was independent of group membership. CONCLUSION Young individuals with AN and those recovered from AN did not differ from controls with respect to neurocognitive performance. Verbal memory was associated with social function in all groups.

Abstract
Objective The aim of this study was to characterise the association between the cognitive profile and weight restoration in children and adolescents with anorexia nervosa. Methods The study was a longitudinal, matched case–control, multicentre study. An assessment of cognitive functions was conducted by using the Wechsler Intelligence Scale for Children–III/the Wechsler Adult Intelligence Scale–III, the Test of Memory and Learning–second edition, Trail Making Tests A and B, the Rey–Osterrieth Complex Figure Test and the Cambridge Neuropsychological Test Automated Battery. Results One hundred twenty individuals, 60 patients with anorexia nervosa with mean age of 14.65 (SD 1.820) years and 60 healthy controls with mean age of 14.76 (SD 1.704) years, participated. No association was found between weight recovery and cognitive functions. However, a significant increase in motor speed was found in Trail Making Test A (p = 0.004), Reaction Time (RTI) five‐choice movement time (p = 0.002) and RTI simple movement time (p = 0.011), resulting in a normalisation corresponding to that found in healthy controls. Furthermore, a significantly lower score in the perceptual organization index (p = 0.029) was found at follow‐up. Conclusions Weight recovery appears not to be associated with cognition.

Abstract
BACKGROUND Clinical and population-based studies report increased prevalence of autism spectrum disorders (ASD) in individuals with anorexia nervosa and in their relatives. No nationwide study has yet been published on co-occurrence of these disorders. AIMS To investigate comorbidity of ASD in individuals with anorexia nervosa, and aggregation of ASD and anorexia nervosa in their relatives. METHOD In Danish registers we identified all individuals born in 1981-2008, their parents, and full and half siblings, and linked them to data on hospital admissions for psychiatric disorders. RESULTS Risk of comorbidity of ASD in probands with anorexia nervosa and aggregation of ASD in families of anorexia nervosa probands were increased. However, the risk of comorbid and familial ASD did not differ significantly from comorbid and familial major depression or any psychiatric disorder in anorexia nervosa probands. CONCLUSIONS We confirm aggregation of ASD in probands with anorexia nervosa and in their relatives; however, the relationship between anorexia nervosa and ASD appears to be non-specific.

Abstract
Objective Few studies of cognitive functioning in children and adolescents with anorexia nervosa (AN) have been conducted. The aim of this study was to examine the neurocognitive and intelligence profile of this clinical group. Method The study was a matched case–control (N = 188), multi-centre study including children and adolescents with AN (N = 94) and healthy control participants (N = 94). Results The results suggest that Full Scale Intelligence Quotient (Wechsler Intelligence Scale for Children-III/Wechsler Adult Intelligence Scale-III) in this patient group is close to the normal population mean of 100. Individuals with AN exhibited significantly worse performance in nonverbal intelligence functions (i.e. Wechsler Intelligence Scale for Children-III/Wechsler Adult Intelligence Scale-III, Perceptual Organization Index) and in verbal memory (Test of Memory and Learning—Second Edition, Memory for Stories) and motor speed (Cambridge Neuropsychological Test Automated Battery, Simple and Choice Reaction Time) compared with healthy control participants. No significant difference in set-shifting ability (Cambridge Neuropsychological Test Automated Battery, Intra-Extra Dimensional Set Shift and Trail Making Test B) was found. Conclusions Inefficiency in nonverbal intelligence functions and in specific cognitive functions was found in this study of children and adolescents with AN. © 2014 The Authors.

Abstract
Primary mediastinal B-cell lymphoma (PMBL) is an aggressive extranodal B-cell non-Hodgkin's lymphoma with specific clinical, histopathological and genomic features. To characterize further the genotype of PMBL, we analyzed 37 tumor samples and PMBL cell lines Med-B1 and Karpas1106P using array-based comparative genomic hybridization (matrix- or array-CGH) to a 2.8k genomic microarray. Due to a higher genomic resolution, we identified altered chromosomal regions in much higher frequencies compared with standard CGH: for example, +9p24 (68%), +2p15 (51%), +7q22 (32%), +9q34 (32%), +11q23 (18%), +12q (30%) and +18q21 (24%). Moreover, previously unknown small interstitial chromosomal low copy number alterations (for example, -6p21, -11q13.3) and a total of 19 DNA amplifications were identified by array-CGH. For 17 chromosomal localizations (10 gains and 7 losses), which were altered in more than 10% of the analyzed cases, we delineated minimal consensus regions based on genomic base pair positions. These regions and selected immunohistochemistries point to candidate genes that are discussed in the context of NF-kappaB transcription activation, human leukocyte antigen class I/II defects, impaired apoptosis and Janus kinase/signal transducer and activator of transcription (JAK/STAT) activation. Our data confirm the genomic uniqueness of this tumor and provide physically mapped genomic regions of interest for focused candidate gene analysis.

Abstract
7513 Background: The addition of etoposide to CHOP (CHOEP) resulted in improved outcome of young patients with good-prognosis aggressive lymphoma (NHL-B1 trial; Blood 2004, 104:626). In order to improve results further, the maximal dose-escalated version of CHOEP-21 tolerable without stem cell support in a preceding dose-escalation study (Hi-CHOEP: C: 1400 mg/m2, H: 65 mg/m2, O: 2 mg, E: 175 mg/m2 × 3, P: 100 mg × 5) was compared to baseline CHOEP-21 in a randomized trial. Methods: Intention-to-treat-analysis comparing CHOEP-21 (n = 194) with Hi-CHOEP (n = 195) in 389 young (18–60 years) patients with good-prognosis (aaIPI = 0,1) aggressive lymphoma. Results: Despite excellent adherence to the protocol (median relative dose of myelosuppressive drugs CHOEP-21: 98%; Hi-CHOEP: 93%), CR/CRu (78.4% vs. 79.5%; p = 0.783), and progressions (12.4% vs. 9.7%; p = 0.409) were not significantly different. After 37 months median observation, there was no difference in the primary endpoint time to treatment failure (64% vs. 68%; p = 0.639) nor overall survival (83% vs. 86%; p = 0.849). Neither low-risk nor low-intermediate risk patients profited from Hi-CHOEP. In a multivariate analysis, elevated LDH and advanced stage (III&IV) were confirmed as independent risk factors for TTF and survival. Hi-CHOEP was considerably more toxic than CHOEP-21 (grade 3 & 4 leukocytopenia 100% vs. 87.2%, p < 0.001, thrombocytopenia 80.8% vs. 9.6%, p < 0.001; infections 19.7% vs. 5.4%, p ≤ 0.001; therapy associated deaths 2.6% vs. 0%). Conclusions: Due to its equal efficacy and lower toxicity, CHOEP-21 is to be preferred over dose-escalated Hi-CHOEP. Our results indicate that dose escalation (in contrast to dose-densification and/or addition of rituximab) does not hold promise for young good-prognosis patients with aggressive lymphoma.

Abstract
Recently, DNA microarray technology has opened new avenues for the understanding of lymphomas. By hybridization of cDNA to arrays containing >10,000 different DNA fragments, this approach allows the simultaneous evaluation of the mRNA expression of thousands of genes in a single experiment. Using sophisticated bioinformatic tools, the huge amount of raw data can be clustered resulting in (1) tumor subclassification, (2) identification of pathogenetically relevant genes, or (3) biological predictors for the clinical course. This approach already has provided novel insights into different entities of B-cell non-Hodgkin's lymphomas. Genomic DNA chip hybridization (matrix-CGH) is a complementary approach focussing on genomic aberrations. In this review, we discuss the impact of this new technology both with regard to methodological aspects as well as to novel findings influencing our understanding of lymphomas.

Abstract
Shiga toxin-producing enterohemorrhagic Escherichia coli is the major cause of acute renal failure in young children. The interaction of Shiga toxins 1 and 2 (Stx1 and Stx2) with endothelial cells is an important step in the renal coagulation and thrombosis observed in hemolytic uremic syndrome. Previous studies have shown that bacterial lipopolysaccharide and host cytokines slowly sensitize endothelial cells to Shiga toxins. In the present study, bacterial neutral sphingomyelinase (SMase) rapidly (1 h) sensitized human dermal microvascular endothelial cells (HDMEC) to the cytotoxic action of Stx2. Exposure of endothelial cells to neutral SMase (0.067 U/ml) caused a rapid increase of intracellular ceramide that persisted for hours. Closely following the change in ceramide level was an increase in the expression of globotriaosylceramide (Gb3), the receptor for Stx2. A rapid increase was also observed in the mRNA for ceramide:glucosyltransferase (CGT), the first of three glycosyltransferase enzymes of the Gb3 biosynthetic pathway. The product of CGT (glucosylceramide) was also increased. In contrast, mRNA for the third enzyme of the pathway, Gb3 synthase, was constitutively produced and was not influenced by SMase treatment of HDMEC. These results describe a rapid response mechanism by which extracellular neutral SMase derived from either bacteria or eukaryotic cells may signal endothelial cells to become sensitive to Shiga toxins.

Abstract
Analysis of genetic alterations in tumor cells represent a first step to understand the molecular mechanism of cancer etiology and development. Due to the progress in genome research, it is feasible to assess the complexity of genomic changes on a large scale. Protocols for gene expression profiling using cDNA arrays have been developed allowing to test the activity of almost all human genes in tumor cells. Another important approach is matrix-CGH which was recently developed to assess gains and losses on the genomic level with high resolution. This method not only allows to narrow down the position of novel oncogenes or tumor suppressor-genes but also contributes to a refinement of tumor classifications. Since matrix-CGH can be performed under highly standardized conditions in a fully automatized way, it is suited for diagnostics in clinical laboratories.

Abstract
Extranodal B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) type may represent a model of lymphoma progression, because a small cell component frequently occurs in the large cell variants. We studied 52 extranodal B-cell lymphomas: 18 extranodal marginal zone B-cell lymphomas of MALT type (MZBL,MT), 7 MZBL,MT of the gastro-intestinal tract with a diffuse large B-cell component (giMZBLplusLBCL), and 27 diffuse large B-cell lymphomas of the gastro-intestinal tract without small cell component (giLBCL). Analytical techniques were comparative genomic hybridization (CGH) and fluorescence in situ hybridization (FISH). The translocation t(11;18) was found as the sole aberration in two MZBL,MT only. In contrast to this, t(11;18)-negative MZBL,MT were characterized by frequent gains on chromosome 3 and DNA amplifications on 2p13-p15. Furthermore, we found a clonal lymphoma progression from the small to the large cell component with accumulation of gains and losses of chromosomal material in the large cell component in giMZBLplusLBCL. Aberrations overlapping with MZBL,MT and giMZBLplusLBCL included losses on chromosome 13, amplifications of the REL proto-oncogene, or gains on chromosome 12. In addition, the large cell component revealed gains on 8q24, including amplifications of the MYC proto-oncogene, and losses on 2q. The giLBCL had frequent gains on chromosomes 12 and 9, as well as on 11q, and losses on 6q. We conclude that, based on the distinctive and partly overlapping patterns of genetic aberrations, MALT lymphomas can be divided into different genetic subgroups.

Abstract
Little is known about the prognostic impact of chromosome aberrations in breast cancer. The aim of our study was to determine whether genomic aberrations of prognostic relevance can be identified in the context of a clinical study using molecular cytogenetics. Paraffin-embedded tumor samples of 44 patients with high-risk stage II/III breast cancer were analyzed by comparative genomic hybridization. All patients received identical therapy including dose-escalated chemotherapy followed by peripheral blood stem cell transplantation. The most frequent chromosomal aberrations were gains on chromosome arms 17q (24 cases), 1q (21 cases), 8q (17 cases), 20q (13 cases), 6p (9 cases) as well as losses on chromosome arms 13q (25 cases), 11q (20 cases), 5q (11 cases), 6q (11 cases), 9p (10 cases), 18q (10 cases), 8p (9 cases) and 16q (9 cases). In univariate analysis, the correlation with the clinical outcome revealed a higher risk for patients with tumors exhibiting 13q losses and a reduced risk for tumors exhibiting 16q losses (p = 0.020), 6q losses (p = 0.041) and estrogen-receptor positivity (0.051). In multivariate analysis using the Cox model, only the loss of 16q exhibited borderline significance (p = 0.065). These data show that comparative genomic hybridization can be performed in the context of a clinical trial. In our subgroup of high-risk breast cancer patients, chromosomal aberrations were valuable prognostic parameters.

Abstract
The B-cell lymphomas of the gastrointestinal (GI) tract have represented a field of extensive research ever since a close association was shown with such chronic inflammatory processes as Helicobacter pylori infection. Evidence suggested that the mucosa-associated lymphoid tissue induced by inflammation and autoimmune processes is the environment that gives rise to the small-cell lymphomas of the GI tract (eg, extranodal marginal zone B-cell lymphoma according to Revised European-American Classification of Lymphoid Neoplasms and the World Health Organization Classification of Neoplastic Diseases of the Hematopoietic and Lymphoid Tissue). The small B-cell lymphoma may then progress to highly malignant variants. The B-cell lymphomas of the GI tract may present a stepwise model for lymphomagenesis and progression. This review covers molecular biology and molecular cytogenetic aspects that lead to new insights into the biology of GI lymphomas and potential prognostic factors.

Abstract
BACKGROUND Microcystic adnexal carcinoma (MAC) is a rare tumor of the skin. Clinically it often masquerades as a firm, subcutaneous nodule on the head and neck regions. Microscopically it extends far beyond assessed clinical margins spreading locally in the dermal, subcutaneous, and perineural tissue planes. The local recurrence rate by standard excision is about 50%. Recent preliminary reports indicate more favorable cure rates with Mohs micrographic surgery (MMS). OBJECTIVE To present our data on 13 cases (12 patients) of MAC treated by MMS. In addition, we reviewed the medical literature to summarize the accumulated experience of MMS treatment in the management of MAC. We also present a case of bilateral MAC of the face and describe a renal transplant recipient on immunosuppressive therapy who developed MAC of the nasal bridge. METHODS We reviewed and updated our series of MAC cases treated by MMS over the last 9 years. A total of 13 cases of MAC are reviewed. We also searched the literature for MAC treated by MMS with a follow-up of more than 2-years. RESULTS One patient had bilateral MAC of the nose and cheek. Another patient developed a MAC of the nasal bridge 20 years after renal transplantation. In this patient predisposing factors were radiation for teenage acne and immunosuppression therapy. A total of 13 cases of MAC were treated by MMS with no recurrences, with a mean follow-up of 5.0 years (range 1.1-8.0 years). CONCLUSION We update the medical literature with 13 MAC cases treated by MMS. To our knowledge there have been 148 cases of MAC reported in the world literature. Including our series, there have been 73 cases of MAC treated with MMS. There were only four treatment failures. Regional and/or distant metastasis from MAC is rare, with only one reported death. Following MMS, the 2-year success rate was 89.7% (35 of 39). The accumulated data continue to confirm that when MAC is discovered early and is readily accessible to excision by MMS and other subspecialty support, a favorable outcome can be expected.

Abstract
Primary mediastinal B-cell lymphoma (MBL) is an aggressive Non-Hodgkin's Lymphoma, which has been recognized as a distinct disease entity. We performed a comprehensive molecular cytogenetic study analyzing 43 MBLs. By comparative genomic hybridization (CGH), the most common aberrations were gains of chromosome arms 9p and Xq, which were present in 56% and 40% of cases, respectively. Based on the limited resolution of CGH, this technique may underestimate the real incidence of aberrations. Therefore, we also did an interphase cytogenetic study with eight DNA probes mapping to chromosome regions frequently altered in B-cell lymphomas. With this approach, both 9p and Xq gains were found in more than 70% of cases (75% and 87%, respectively). The findings were compared with results obtained in 308 other B-cell lymphomas. Gains in 9p were identified in only six of the 308 cases, and only one of these lymphomas with 9p gains was not primarily extranodal in origin (P < 10-(20) for CGH data and P < 10-(11) for fluorescence in situ hybridization data). We also present a novel MBL cell line, MedB-1, which carries the genetic aberrations characteristic of this entity.

Abstract
BACKGROUND Merkel cell carcinoma (MCC) is an uncommon skin tumor that most frequently arises on sun-exposed facial sites. It rarely occurs on mucous membranes of the head region. The primary MCC is usually treated by wide excision followed by radiation to the primary site and regional lymph nodes. Using traditional surgery the local recurrence rate ranges from 20 to 50%. In our clinic, Mohs surgery is used to excise the primary MCC completely, followed by radiation. Here we present our treatment experiences and outcomes. OBJECTIVE To document our experience of MCC treated by Mohs surgery. We present our series of 12 cases of MCC, 2 cases of which arose from mucosal sites of the nasal cavity. METHODS We reviewed 12 cases of MCC from the Mohs clinic database. We also reviewed the literature for cutaneous and mucosal MCC. RESULTS There were 12 cases of MCC: 10 cutaneous and 2 mucous. The site distribution of cutaneous MCC was eight on the head, one on the neck, and one on the groin. Of these, nine were treated by Mohs excision. Two patients developed local recurrence following Mohs treatment. The local recurrence rate was 22% (2 of 9). The sites of mucosal MCC were the nasal septum and nasopharynx. One case had a history of previous radiation and developed an MCC 40 years later. This case also demonstrated epidermotropic spread of Merkel cells to the overlying mucous epithelium. This patient required extensive intranasal and cranial surgery to remove the tumor. Both patients with mucosal MCCs died of their disease. The overall mucocutaneous survival of MCC at 1 year was 80% and at 2 years was 50%. CONCLUSION In our series, local control of the primary MCC was achieved in 70% of patients (7 of 10) using combined Mohs excision and radiation. Two recurrences had primary tumors larger than 3.5 cm in diameter, while the other case was nonresectable by Mohs surgery. Tumor size appeared to determine the degree of local control. When the postoperative Mohs defect was less than 3.0 cm in diameter, local and regional control appeared to be more favorable. When the primary facial MCC is relatively small, removal by Mohs surgery followed by radiation was effective, therapeutic, and less disfiguring. Mucosal MCC is rare and may occur as a long-term sequelae after radiation therapy to the skin.

Abstract
Secondary chromosomal aberrations in follicle center cell derived lymphomas (FCDL) usually involve gains and losses of genetic material and may be an important prognostic value. In the present study, we aimed to determine the power of comparative genomic hybridization (CGH) as compared to standard chromosome analysis (CA) to detect such secondary aberrations. The same lymph node cell suspensions prepared from 30 patients with FCDL were analyzed in parallel by CGH and CA based on R banding. In all, 73 discrepancies were found. Sixty-two imbalances were detected only by CA and 11 only by CGH. In cases with completely resolved karyotypes (n= 17), the median number of discrepancies between CGH and CA was one. However, when the karyotype was partially resolved (n = 12), the median was four (P < 0.01). Discrepant results were further studied by fluorescence in situ hybridization using locus-specific probes. These data confirm, that not only for the detection of balanced aberrations, but also for the detection of unbalanced aberrations in FCDL, standard chromosome analysis is still the 'gold standard'. In contrast, CGH is useful to detect chromosomal imbalances when no metaphases are found or no fresh material is available.

Abstract
Cytogenetic methods have become increasingly important tools for both research in hematological malignancies and for the diagnostic workup of leukemias and lymphomas. The knowledge about specific chromosomal aberrations has been an essential prerequisite for the identification of pathogenetically relevant genes. Important examples are molecular genetic analyses of the breakpoint regions in chromosomal translocations, which resulted in the detection of protooncogenes such as ABL in chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL) [t(9,22)(q34;q11)], or MYC in Burkitt's lymphoma [t(8;14)(q24;q32); for a review see refs. 1 and 2].

Abstract
BACKGROUND Fluorescence in situ hybridization has improved the detection of genomic aberrations in chronic lymphocytic leukemia. We used this method to identify chromosomal abnormalities in patients with chronic lymphocytic leukemia and assessed their prognostic implications. METHODS Mononuclear cells from the blood of 325 patients with chronic lymphocytic leukemia were analyzed by fluorescence in situ hybridization for deletions in chromosome bands 6q21, 11q22-23, 13q14, and 17p13; trisomy of bands 3q26, 8q24, and 12q13; and translocations involving band 14q32. Molecular cytogenetic data were correlated with clinical findings. RESULTS Chromosomal aberrations were detected in 268 of 325 cases (82 percent). The most frequent changes were a deletion in 13q (55 percent), a deletion in 11q (18 percent), trisomy of 12q (16 percent), a deletion in 17p (7 percent), and a deletion in 6q (7 percent). Five categories were defined with a statistical model: 17p deletion, 11q deletion, 12q trisomy, normal karyotype, and 13q deletion as the sole abnormality; the median survival times for patients in these groups were 32, 79, 114, 111, and 133 months, respectively. Patients in the 17p- and 11q-deletion groups had more advanced disease than those in the other three groups. Patients with 17p deletions had the shortest median treatment-free interval (9 months), and those with 13q deletions had the longest (92 months). In multivariate analysis, the presence or absence of a 17p deletion, the presence or absence of an 11q deletion, age, Binet stage, the serum lactate dehydrogenase level, and the white-cell count gave significant prognostic information. CONCLUSIONS Genomic aberrations in chronic lymphocytic leukemia are important independent predictors of disease progression and survival. These findings have implications for the design of risk-adapted treatment strategies.

Abstract
Comparative genomic hybridization (CGH) has contributed significantly to the current knowledge of genomic alterations in hematologic malignancies. Characteristic patterns of genomic imbalances not only have confirmed recent classification schemes in non-Hodgkin's lymphoma, but they provide a basis for the successful identification of genes with previously unrecognized pathogenic roles in the development of different lymphomas. Based on its technical limitations, there is little reason to apply CGH to chromosomes of metaphase cells in routine diagnostic settings. However, the new approach of CGH to DNA microarrays, a procedure termed matrix-CGH, overcomes most of the limitations and opens new approaches for diagnostics and identification of genetically defined leukemia and lymphoma subgroups. Current efforts to develop leukemia specific matrix-CGH DNA chips, which are designed to meet the clinical needs, are presented and discussed.

Abstract
A physiological examination of mice harboring a null allele at the aryl hydrocarbon (Ah) locus revealed that the encoded aryl hydrocarbon receptor plays a role in the resolution of fetal vascular structures during development. Although the aryl hydrocarbon receptor is more commonly studied for its role in regulating xenobiotic metabolism and dioxin toxicity, a developmental role of this protein is supported by the observation that Ah null mice display smaller livers, reduced fecundity, and decreased body weights. Upon investigating the liver phenotype, we found that the decrease in liver size is directly related to a reduction in hepatocyte size. We also found that smaller hepatocyte size is the result of massive portosystemic shunting in null animals. Colloidal carbon uptake and microsphere perfusion studies indicated that 56% of portal blood flow bypasses the liver sinusoids. Latex corrosion casts and angiography demonstrated that shunting is consistent with the existence of a patent ductus venosus in adult animals. Importantly, fetal vascular structures were also observed at other sites. Intravital microscopy demonstrated an immature sinusoidal architecture in the liver and persistent hyaloid arteries in the eyes of adult Ah null mice, whereas corrosion casting experiments described aberrations in kidney vascular patterns.

Abstract
The BCL10 gene has recently been cloned from the 1p22 breakpoint of the translocation t(1 ;14)(p22;q32) observed in mucosa-associated lymphoid tissue (MALT) lymphoma. BCL10 was shown to be a proapoptotic-signaling gene encoding a protein that contains an amino-terminal caspase recruitment domain (CARD). Mutations within the BCL10 coding region resulting in truncated BCL10 proteins with loss of their proapoptotic function and preservation of their NF-kappaB activating function were detected in MALT lymphoma. Based on these findings it was proposed that BCL10 might have tumor suppressor function. Deletions involving 1p22 are commonly observed in mantle cell lymphoma (MCL). To investigate its role in MCL we have analyzed a series of 15 MCL for deletion and mutation of BCL10. Monoallelic 1p22 deletions were detected by fluorescence in situ hybridization in five of the 15 cases and were shown to affect BCL10 in all cases. BCL10 was screened for mutations by DNA sequencing of RT-PCR amplified transcripts. In none of the 15 MCL cases studied were mutations found in the BCL10 coding region. A previously reported polymorphism exhibiting a silent 24C > G substitution was found in eight MCL cases and in four healthy probands. A missense mutation 13G >T resulting in a substitution of a serine by an alanine was seen in one of the controls. Our results strongly suggest that BCL10 is not the candidate tumor suppressor gene inactivated by deletion or mutation in band 1p22 in MCL.

Abstract
Comparative genomic hybridization, a widely used method for screening for genomic imbalances, suffers from a lack of standardized evaluation. In order to compare a recently proposed data-driven procedure with the commonly used fixed cutoff values, we tested 257 events by both procedures as well as by fluorescence in situ hybridization using selected probes. With the data-driven procedure, a much higher fraction (42/218 vs. 8/218) of false positive results was obtained, whereas a higher sensitivity with respect to the detection of imbalances (30/39 vs. 19/39) was reached. Based on the significantly higher positive likelihood ratios and the positive predictive value, we strongly recommend the use of fixed diagnostic thresholds, because the alternative procedure generates an unacceptably high portion of incorrectly scored chromosomal imbalances.
