Chron’s Disease is a chronic inflammatory intestinal disease, first described at the beginning of the last century. The disease is characterized by the alternation of periods of flares and remissions influenced by a complex pathogenesis in which inflammation plays a key role. Crohn’s disease evolution is mediated by a complex alteration of the inflammatory response which is characterized by alterations of the innate immunity of the intestinal mucosa barrier together with a remodeling of the extracellular matrix through the expression of metalloproteins and increased adhesion molecules expression, such as MAcCAM-1. This reshaped microenvironment enhances leucocytes migration in the sites of inflammation, promoting a T H 1 response, through the production of cytokines such as IL-12 and TNF-α. IL-12 itself and IL-23 have been targeted for the medical treatment of CD. Giving the limited success of medical therapies, the treatment of the disease is invariably surgical. This review will highlight the role of inflammation in CD and describe the surgical approaches for the prevention of the almost inevitable recurrence.

BackgroundCognitive impairments in patients with myotonic dystrophy type 1 (DM1) have often been described, however, there are only few studies differentiating between partial performance disorders and mental retardation in common. This study focused on the evaluation of reading performance and the frequency of dyslexia in adult DM1 patients.MethodsWe performed a prospective cohort study including genetically confirmed adult DM1 patients registered in the DM registry of Germany or the internal database of the Friedrich-Baur-Institute, Munich, Germany. For the assessment of the patients’ reading and spelling performance, we used the standardized and validated test ‚Salzburger Lese- und Rechtschreibtest‘ (SLRT II). The ‚CFT-20 R Grundintelligenztest Skala 2‘ in revised (\"R\") version (CFT 20-R), determining the intelligence level, was appropriate to differentiate between dyslexia and general mental retardation. The diagnosis of dyslexia, the combined reading and spelling disorder, was based on the guidelines for diagnosis and therapy of children and adolescents with dyslexia 2015 (S3-guideline) providing (1) the criterion of the divergence from age level and (2) the criterion of IQ-divergence. ResultsFifty-seven DM1 patients participated in our study. Evaluating the reading performance, 16 patients fulfilled the divergence criteria of the age level and 2 patients the IQ-divergence criteria. In total, the diagnosis of a reading disorder was given in 18 DM1 patients (31.6 %). In 11 out of these 18 patients with a reading disorder, a relevant impairment of spelling performance was observed with at least three spelling errors. As there are no normative values for adults in spelling performance, we assume a combined reading disorder and dyslexia, in those 11 DM1 patients (19.3 %). Regarding the separate analyses of the test procedures, in the SLRT II the performance was below average in 40.4 % of all patients for ‘word reading’ and in 61.4 % of all patients for ‘pseudoword reading’. There was a significant positive correlation between the CTG expansion size and a reading disorder (p=0.027). The average IQ of 17 examined DM1 patients was in the lower normal range (86.1 ± 19.1). 54.5 % of patients with reading disorder had a normal IQ. ConclusionThe calculated prevalence of dyslexia in the DM1 study cohort was 19.3 % and thus considerably increased compared to the normal German population. As dyslexia is not equivalent to a general cognitive impairment, it is important not to miss dyslexic features in cognitive inconspicuous DM1 patients. Case-by-case one should consider a differential diagnostic approach, as individualized therapies can be offered to support dyslexic patients in their performance.

ObjectiveA multicentre observational study was aimed to assess the prevalence of late-onset Pompe disease (LOPD) in a large high-risk population, using the dried blood spot (DBS) as a main screening tool.Design/methods17 Italian neuromuscular centres were involved in the late-onset Pompe early diagnosis (LOPED) study. Inclusion criteria were: (1) age ≥5 years, (2) persistent hyperCKaemia and (3) muscle weakness at upper and/or lower limbs (limb-girdle muscle weakness, LGMW). Acid α-glucosidase (GAA) activity was measured separately on DBS by fluorometric as well as tandem mass spectrometry methods. A DBS retest was performed in patients resulted positive at first assay. For the final diagnosis, GAA deficiency was confirmed by a biochemical assay in skeletal muscle, whereas genotype was assessed by GAA molecular analysis.ResultsIn a 14-month period, we studied 1051 cases: 30 positive samples (2.9%) were detected by first DBS screening, whereas, after retesting, 21 samples were still positive. Biochemical and molecular genetic studies finally confirmed LOPD diagnosis in 17 cases (1.6%). The median time from the onset of symptoms/signs to diagnosis was 5 years. Among those patients, 35% showed presymptomatic hyperCKaemia and 59% showed hyperCKaemia+LGMW, whereas 6% manifested with LGMW.ConclusionsLOPED study suggests that GAA activity should be accurately screened by DBS in all patients referring for isolated hyperCKaemia and/or LGMW. A timely diagnosis was performed in five patients with presymptomatic hyperCKaemia, but two had already manifested with relevant changes on muscle morphology and MRI. Consequently, enzyme replacement therapy was started in 14/17 patients, including the 2 patients still clinically presymptomatic but with a laboratory evidence of disease progression.

Background The symptomatic treatment of myotonia and myalgia in patients with dystrophic and non-dystrophic myotonias is often not satisfactory. Some patients anecdotally report symptoms’ relief through consumption of cannabis. Methods A combination of cannabidiol and tetrahydrocannabinol (CBD/THC) was prescribed as compassionate use to six patients (four patients with myotonic dystrophy types 1 and 2, and 2 patients with CLCN1-myotonia) with therapy-resistant myotonia and myalgia. CBD/THC oil was administered on a low dose in the first 2 weeks and adjusted to a higher dose in the following 2 weeks. Myotonia behaviour scale (MBS), hand-opening time, visual analogue scales (VAS) for myalgia and myotonia, and fatigue and daytime sleepiness severity scale (FSS, ESS) were performed weekly to monitor treatment response. Results All patients reported an improvement of myotonia especially in weeks 3 and 4 of treatment: MBS improved of at least 2 points in all patients, the hand-opening time variously improved in 5 out of 6 patients. Chronic myalgia was reported by both DM2 patients at baseline, one of them experienced a significant improvement of myalgia under treatment. Some gastrointestinal complaints, as abdominal pain and diarrhoea, improved in 3 patients; however, 4 out of 6 patients reported new-onset constipation. No other relevant side effect was noticed. Conclusions These first empirical results suggest a potentially beneficial role of CBD/THC in alleviating myotonia and should encourage further research in this field including a randomized-controlled trial on larger cohorts.

The aim of this study was to determine the perioperative behavior of C-reactive protein (CRP) in Crohn’s disease (CD) patients undergoing elective ileo-cecal (IC) resection and to identify association between perioperative CRP levels and endoscopic recurrence at 1 year. Study hypothesis was that perioperative CRP changes are disease specific and could detect subset of patients with more aggressive pathopysiology. Seventy-five patients undergoing IC resection for CD were prospectively enrolled. Serial CRP levels were assessed: preoperative, postoperative day 1 (POD1) and day 5 (POD5). CD patients’ values were compared against same interval assessments of control groups undergoing right colectomy and appendicectomy. At POD1, the serum concentration increase was significantly higher in CD patients than in controls. Comparing with control groups, CRP levels remained remarkably high and showed a lower reduction in CD at POD5. Difference between groups was statistically significant. Optimal cutoff levels have been identified: serum CRP concentrations of >39.8 mg/l at POD1 and of >23.2 mg/l at POD5 have shown a significant association to endoscopic recurrence when using bivariate correlation. In this preliminary series, binary logistic regression could not demonstrate statistical relationship between endoscopic recurrence and any of the variables evaluated as prognostic factor. This is the only study so far that investigates and confirms a disease-specific upregulation of CRP response in the perioperative period for CD patients undergoing surgery. The postoperative CRP levels and kinetics seem to be related to the grade of mucosal inflammation and recurrence rate according to our 12 months endoscopic evaluation.

Background: Wireless vital parameter continuous monitoring (WVPCM) after discharge is compared to regular monitoring to provide data on the clinical-economic impact of complex patients (CPs) discharged from Internal Medicine Units of Ospedale dei Castelli, Lazio. Primary outcome: Major complications (MC) reduction. Secondary outcomes: Patients who reached discharge criteria within the 7th day from admission; difference in MC incidence at the conclusion of the standard telemonitoring/clinical monitoring phase, 5 and 30 days after discharge; and conditions predisposing to MC occurrence. Methods: Open label randomized controlled trial with wearable wireless system that creates alerts on portable devices. Continuous glycemic monitoring is performed for patients with diabetes mellitus. Results: There were 110 patients enrolled (mean age: 76.2 years). Comorbidity: Cumulative Illness Rating Scale CIRS-CI (comorbidities index): 3.93, CIRS SI (severity index): 1.93. About 19% scored a BRASS (Blaylock Risk Assessment Screening Score) ≥20 indicating need for discharge planning requiring step-down care. Globally, 48% of patients in the control group had major complications (27 out of 56 patients), in contrast to 22% in the intervention group (12 out of 54 patients). Conclusions: Since WVPCM detects early complications during the post-discharge CPs monitoring, it increases safety and reduces inappropriate access to the Emergency Room, preventing avoidable re-hospitalizations.

Background and purpose The Rasch‐Built Pompe‐Specific Activity (R‐PAct) scale is a patient‐reported outcome measure specifically designed to quantify the effects of Pompe disease on daily life activities, developed for use in Dutch‐ and English‐speaking countries. This study aimed to validate the R‐PAct for use in other countries. Methods Four other language versions (German, French, Italian, and Spanish) of the R‐PAct were created and distributed among Pompe patients (≥16 years old) in Germany, France, Spain, Italy, and Switzerland and pooled with data of newly diagnosed patients from Australia, Belgium, Canada, the Netherlands, New Zealand, the USA, and the UK and the original validation cohort (n = 186). The psychometric properties of the scale were assessed by exploratory factor analysis and Rasch analysis. Results Data for 520 patients were eligible for analysis. Exploratory factor analysis suggested that the items separated into two domains: Activities of Daily Living and Mobility. Both domains independently displayed adequate Rasch model measurement properties, following the removal of one item (\"Are you able to practice a sport?\") from the Mobility domain, and can be added together to form a \"higher order\" factor as well. Differential item functioning (DIF)‐by‐language assessment indicated DIF for several items; however, the impact of accounting for DIF was negligible. We recalibrated the nomogram (raw score interval‐level transformation) for the updated 17‐item R‐PAct scale. The minimal detectable change value was 13.85 for the overall R‐PAct. Conclusions After removing one item, the modified‐R‐PAct scale is a valid disease‐specific patient‐reported outcome measure for patients with Pompe disease across multiple countries.

Background & Purpose: The musculature of patients suffering from neuromuscular diseases (NMD) is mainly affected by atrophy/hypertrophy, fatty infiltration, and/or edematous changes [1]. Therefore, MRI is an important tool for diagnosis and monitoring. Concerning fatty infiltration, standard T1-weighted or T2-weighted DIXON TSE sequences enable a qualitative assessment of muscle involvement [2]. To achieve higher comparability semi-quantitative grading scales, such as the 4-point Mercuri scale [3], can be applied. However, the evaluation remains dependent on the reader's judgment. Therefore, effort is being invested to develop quantitative MRI techniques, such as proton density fat fraction (PDFF) mapping. The present work aims to assess the diagnostic value of PDFF mapping in correlation to Mercuri grading in patients with DM2, LGMD2A, and Pompe disease. Methods: T2-weighted DIXON TSE and PDFF mapping were performed in 13 patients (DM2: n = 5; LGMD2A: n = 5; Pompe disease: n = 3). Nine different thigh muscles were rated in all patients according to the Mercuri grading and segmented to extract PDFF values. Results: Mean PDFF values ranged from 7 to 37% in Pompe and DM2 patients and up to 79% in LGMD2A patients (Fig. 1). In all three groups a high correlation of the Mercuri grading and PDFF values was observed (Table 1). Conclusion: In the investigated patient groups PDFF mapping offers the same diagnostic value as the clinically established Mercuri grading. With its greater dynamic range (enabling the assessment of more subtle changes) and the increased objectivity, PDFF should be considered a potential biomarker and alternative to Mercuri grading in the assessment of fatty infiltration of muscle tissue.

Objectives: To compare whole body and regional (arms, legs and trunk) fat mass, fat-free mineral-free mass, bone mineral content and bone mineral density, measured by DXA, in cirrhotic patients and age, sex and BMI matched healthy volunteers. Design: Cross-sectional study. Setting: Two medical research institutions. Subjects: Twenty-two non ascitic cirrhotic patients and 16 age, sex and BMI matched healthy volunteers. Interventions: The Lunar DPX whole-body X-ray densitometer with Lunar software version 3.6z (Lunar Radiation Corp., Madison WI, USA) was used. Regional analysis was performed on the arms, legs, trunk and head. Results: Compared to controls, cirrhotic patients showed a significant reduction in percentage body fat. When differentiated by gender, however, the reduction in percentage body fat was evident in female cirrhotics only, particularly in the trunk. In male cirrhotic patients fat-free mineral-free mass was reduced in absolute terms in the whole body and the limbs. For both genders and in each body segment bone mineral content and density were reduced in cirrhotics compared to controls. In cirrhotic patients bone mineral density was significantly correlated to both fat-free, mineral-free mass (r=0.85; P <0.001) and to the Physical Activity Index (r=0.52; P <0.0l). Conclusions: Two different patterns of soft tissue loss may be found in cirrhotic patients: in women lean tissue is maintained while fat stores are reduced, as in early starvation; in men lean tissue is reduced, as seen under conditions of stress. Moreover, factors influencing lean body mass, such as nutritional depletion and physical inactivity, may contribute to the reduction of bone density frequently observed in cirrhotic patients.

Orbital myositis (OM) is a rare disease whose clinical heterogeneity and different treatment options represent a diagnostic and therapeutic challenge. We aim to review the state of knowledge on OM, also describing a cohort of patients diagnosed in our centre, to highlight some remarkable clinical features. A literature review was conducted in PubMed and Medline databases. The herein described cohort is composed of seven OM patients, diagnosed according to clinical, laboratory and neuroradiological features, whose clinical data were retrospectively analysed. OM is a non-infectious, inflammatory process primarily involving extraocular eye-muscles. It typically presents as an acute to sub-acute, painful ophthalmoplegia with signs of ocular inflammation, but atypical cases without pain or with a chronic progression have been described. The wide range of OM mimicking diseases make a prompt diagnosis challenging but orbit MRI provides valuable clues for differential diagnosis. Timely treatment is greatly important as OM promptly responds to steroids; nevertheless, partial recovery or relapses often occur. In refractory, recurrent or steroid-intolerant cases other therapeutic options (radiotherapy, immunosuppressants, immunoglobulins) can be adopted, but the most effective therapeutic management is yet to be established. In this review, we provide a detailed clinical description of OM, considering the main differential diagnoses and suggesting the most useful investigations. In light of the currently available data on therapy efficacy, we propose a therapeutic algorithm that may guide neurologists in OM patients’ management.
