Background: Certain immunotoxic peptides from gluten are resistant to gastrointestinal digestion and can interact with celiac-patient factors to trigger an immunologic response. A gluten-free diet (GFD) is the only effective treatment for celiac disease (CD), and its compliance should be monitored to avoid cumulative damage. However, practical methods to monitor diet compliance and to detect the origin of an outbreak of celiac clinical symptoms are not available. Objective: We assessed the capacity to determine the gluten ingestion and monitor GFD compliance in celiac patients by the detection of gluten and gliadin 33-mer equivalent peptidic epitopes (33EPs) in human feces. Design: Fecal samples were obtained from healthy subjects, celiac patients, and subjects with other intestinal pathologies with different diet conditions. Gluten and 33EPs were analyzed by using immunochromatography and competitive ELISA with a highly sensitive antigliadin 33-mer monoclonal antibody. Results: The resistance of a significant part of 33EPs to gastrointestinal digestion was shown in vitro and in vivo. We were able to detect gluten peptides in feces of healthy individuals after consumption of a normal gluten-containing diet, after consumption of a GFD combined with controlled ingestion of a fixed amount of gluten, and after ingestion of <100 mg gluten/d. These methods also allowed us to detect GFD infringement in CD patients. Conclusions: Gluten-derived peptides could be sensitively detected in human feces in positive correlation with the amount of gluten intake. These techniques may serve to show GFD compliance or infringement and be used in clinical research in strategies to eliminate gluten immunotoxic peptides during digestion. This trial was registered at clinicaltrials.gov as NCT01478867. © 2012 American Society for Nutrition.


Despite major improvements in diagnostics and interventional therapies, cardiovascular diseases remain a major health care and socio-economic burden both in western and developing countries, in which this burden is increasing in close correlation to economic growth. Health authorities and the general population have started to recognize that the fight against these diseases can only be won if their burden is faced by increasing our investment on interventions in lifestyle changes and prevention. There is an overwhelming evidence of the efficacy of secondary prevention initiatives including cardiac rehabilitation in terms of reduction in morbidity and mortality. However, secondary prevention is still too poorly implemented in clinical practice, often only on selected populations and over a limited period of time. The development of systematic and full comprehensive preventive programmes is warranted, integrated in the organization of national health systems. Furthermore, systematic monitoring of the process of delivery and outcomes is a necessity. Cardiology and secondary prevention, including cardiac rehabilitation, have evolved almost independently of each other and although each makes a unique contribution it is now time to join forces under the banner of preventive cardiology and create a comprehensive model that optimizes long term outcomes for patients and reduces the future burden on health care services. These are the aims that the Cardiac Rehabilitation Section of the European Association for Cardiovascular Prevention & Rehabilitation has foreseen to promote secondary preventive cardiology in clinical practice. © The European Society of Cardiology 2012 Reprints and permissions: sagepub.co.uk/ journalsPermissions.nav.

Objective In the present study an attempt was made to quantify and characterise the changes in the intracranial pressure (ICP) waveform over the wide pressure range covered during infusion studies by means of the central tendency measure (CTM). CTM is a non-linear approach using continuous chaotic modelling that summarises the degree of variability in a signal. Methods CTM of the ICP wave in the lumbar subarachnoid space was analysed in 77 infusion studies performed in patients with idiopathic and secondary forms of normal pressure hydrocephalus (median age 74 years, range 22- 88). Four artefact-free epochs were selected during the baseline, infusion, plateau and relaxation stages of every infusion study. The average pressure, pulse amplitude and CTM were determined for each epoch. Correlations among these parameters were explored. Results CTM of the ICP waveform decreases, i.e. variability increases, as infusion studies progress from baseline pressure to the plateau stage. Significant correlations were found during all phases of infusion testing, except at baseline, between CTM and pressure, CTM and amplitude and pressure and amplitude. Partial correlations emphasised the relationship between CTM and amplitude. When pulse amplitude is held constant, CTM and the pressure range do not correlate. Conclusions Volume loading leads to increased variability of the ICP signal measured by means of CTM. This finding summarises numerically the long-established phenomenon of increasing amplitude and rounding of ICP pulses associated with ICP elevation during infusion studies. CTM could be a suitable approach to quantify and characterise the pulsatile nature of the ICP wave. © Springer-Verlag 2012.

AML is an aggressive hematological malignancy with highest incidence in the older adults. The adverse features of AML in the elderly, and the frailties and comorbidities frequently present in them, make their management a particularly difficult therapeutic challenge. In this context, it is important to assess carefully patient- as well as disease-associated prognostic features with validated tools. The fittest patients should be considered for curative therapy, such as bone marrow transplantation, whereas low intensity options may be more appropriate for frail patients. Here we review how to assess patients with elderly AML and the treatments options available for them. © 2016 The Authors.

To establish evidence-based recommendations regarding the use of anti-Tumor Necrosis Factor alpha (TNF-α) agents for managing uveitis patients. Medline was searched via OVID (1950 - October Week 3, 2011) using a Cochrane highly sensitive search (phases 1 and 2). Additional literature searches were also conducted incuding the following databases: the Cochrane, LILACS and the TRIP Database. A total of 54 studies met all of the inclusion criteria and were included in this review. A different level of recommendation and evidence is assigned to each anti-TNF-α agent. The overall rate of reported side effects with anti-TNF-α agents for the treatment of uvetis which required discontinuation of therapy was 2.2% (26/1147 patients). Based on the evidence gathered, infliximab and adalimumab seem to be effective in the management of immune-mediated uveitis. Further randomized studies evaluating the efficacy of these agents are warranted. It is the most common cause of inflammatory eye disease, with an estimated prevalence of 115 cases per 100,000 persons. Endogenous or associated with a systemic disease, noninfectious uveitis accounts for approximately 75% of total cases comprising of a heterogeneous group of inflammatory conditions responsible for about 10% of legal blindness in developed nations. Endogenous uveitides are thought to have an autoimmune component mediated by T lymphocytes specific to intraocular antigens that have failed to successfully pass basic processes designed to maintain self-tolerance.

Aneurysms of peripheral arteries are infrequent, with an incidence <1%. Dorsalis pedis artery (DPA) aneurysms are extremely rare, and most of them are pseudoaneurysms secondary to trauma or iatrogenic injuries. We report the first case of simultaneous (synchronous) bilateral DPA true aneurysms and how we repaired them. We review the literature on DPA true aneurysms and focus on the surgical management.

The systematic analysis of a carpal transverse ligament (CTL) sample obtained during routine carpal tunnel syndrome (CTS) surgery may constitute a method of early diagnosis for systemic amyloidosis.Prospective study carried out on 147 consecutive CTL samples collected from patients intervened for CTS at the University Hospital of Len from April 2006 to May 2007. In those cases in which amyloid deposition was observed in the CTL sample, the study was completed with a fine needle aspiration biopsy (FNAB) of the subcutaneous fascia, using the Red Congo stain in both cases. Positive cases were referred to the Internal Medicine and/or Hematology departments, and their evolution was monitored for up to 8 years.CTL amyloid deposition was observed in 29 patients (19.7%), with a FNAB only being performed in 19 of them (65.5%). The test was positive in 11 cases (57.9%), and 4 patients in this subgroup (3% of the total) developed events attributable to amyloidosis over the following 3 years.A CTL routine biopsy carried out during CTS surgery may anticipate the systemic amyloidosis diagnosis.

Barretts oesophagus (BE) is an oesophageal injury caused by gastroesophageal acid reflux. One of the main aims of treatment in BE is to achieve adequate acid reflux control.To assess acid reflux control in patients with BE based on the therapy employed: medical or surgical.A retrospective study was performed in patients with an endoscopic and histological diagnosis of BE. Medical therapy with proton pump inhibitors (PPI) was compared with surgical treatment (Nissen fundoplication). Epidemiological data and the results of pH monitoring (pH time <4, prolonged reflux >5min, DeMeester score) were evaluated in each group. Treatment failure was defined as a pH lower than 4 for more than 5% of the recording time.A total of 128 patients with BE were included (75 PPI-treated and 53 surgically-treated patients). Patients included in the two comparison groups were homogeneous in terms of demographic characteristics. DeMeester scores, fraction of time pH<4 and the number of prolonged refluxes were significantly lower in patients with fundoplication versus those receiving PPIs (P<.001). Treatment failure occurred in 29% of patients and was significantly higher in those receiving medical therapy (40% vs 13%; P<.001).Treatment results were significantly worse with medical treatment than with anti-reflux surgery and should be optimized to improve acid reflux control in BE. Additional evidence is needed to fully elucidate the utility of PPI in this disease.
