Practical aspects of high resolution esophageal manometry.

High resolution esophageal manometry (HRM) is currently under development as can be seen in the various Chicago classifications. In order to standardize criteria in certain practical aspects with limited scientific evidence, the First National Meeting for Consensus in High Resolution Manometry of the Spanish Digestive Motility Group took place, bringing together a wide group of experts. The proposals were based on a prior survey composed of 47 questions, an exhaustive review of the available literature and the experience of the participants.

Esophageal Cicatricial Pemphigoid as an Isolated Involvement Treated with Mycophenolate Mofetil.

Cicatricial pemphigoid (CP) is a rare blistering autoimmune disease. Esophageal involvement occurs in widespread disease and rarely appears as the only affected organ. We report a 67-year-old Caucasian female with esophageal dysphagia and weight loss.

[Acute pancreatitis and space-occupying hepatic lesions in a patient with bone marrow transplant due to multiple myeloma].

Patients with multiple myeloma (MM) do not have a higher incidence of acute pancreatitis or pancreatitis of other etiologies than the general population. However, these patients may develop acute pancreatitis, or hyperamylasemia or isolated hyperlipasemia, due to etiologies that are highly infrequent in the absence of hematological disease. Liver involvement is found in 30-50% of patients with MM and mainly manifests as diffuse sinusoidal infiltration and less frequently in the form of nodules.

Thymidylate synthase expression pattern, expression level and single nucleotide polymorphism are predictors for disease-free survival in patients of colorectal cancer treated with 5-fluorouracil.

Several variables associated to thymidylate synthase (TS), the biological target of 5-fluorouracil (5FU) have been studied for their possible role as predictors of the clinical outcome and response to chemotherapy in colorectal cancer (CRC) patients. The level of protein expression and the number of variable tandem-repeats of a 28-bp sequence within the gene promoter have been proposed as predictive and/or prognostic factors with variable agreement, while consensus seems to be achieved with respect to the value of a single nucleotide polymorphism (SNP) described within this same region. More recently, an association between TS expression pattern and survival has been disclosed.
