Introduction: Liquid biopsy is an innovative and efficient method for studying circulating tumor DNA. In conjunction with innovative techniques such as next-generation sequencing, it can provide real-time information on prognostic and predictive factors.

Case Presentation: We report a case of advanced, unresectable medullary thyroid carcinoma with various rearranged during transfection (RET) and Kirsten rat sarcoma viral (KRAS) mutations in both blood liquid and tissue biopsies.

Introduction: Standard therapy with corticosteroids (CS) and cyclophosphamide (CYC) followed by azathioprine has been shown to improve renal and patient survival in ANCA-associated renal vasculitis (rAAV). Mycophenolate mofetil (MF) has been progressively introduced for the treatment of rAAV in the last years because of its immunosuppressive efficacy combined with a lower toxicity profile. In this study, we retrospectively analyse the results of the introduction of MF for maintenance and induction therapy in rAAV in our institution from 2001 to 2013.

Microparticles (MP) are considered a key component in the haemostatic response. Beyond their in vitro procoagulant properties, a number of pieces of evidence points to procoagulant MP as efficient effectors in the haemostatic response and as pathogenic markers of thrombotic disorders and vascular damage. The aim of the present study was to analyze the procoagulant activity of MP and its correlation with clinical manifestations focusing on vascular involvement in patients with Behçet's disease (BD).

Splenectomy has been used in patients with common variable immunodeficiency disorders (CVID), mainly in the context of refractory autoimmune cytopenia and suspected lymphoma, but there are understandable concerns about the potential of compounding an existing immunodeficiency. With increasing use of rituximab as an alternative treatment for refractory autoimmune cytopenia, the role of splenectomy in CVID needs to be re-examined. This retrospective study provides the largest cohesive data set to date describing the outcome of splenectomy in 45 CVID patients in the past 40 years.

Background: To describe the clinical characteristics and evolution of a series of adult patients hospitalized for neuro-Behçet disease (NBD).

Methods: Consecutive patients admitted for NBD in a teaching hospital were retrospectively selected. Disability at discharge and during follow-up was graded with the modified Rankin Scale, and outcome classified as good or poor (grades 3-6).

Recently, an acute restriction of imiglucerase has occurred as a result of viral contamination and manufacturing problems. A position statement from the European Working Group for Gaucher Disease and European Gaucher Alliance established a set of key recommendations for identifying and monitoring at-risk patients. In Spain, a profile of the shortage situation was obtained through follow-up of patients with Gaucher disease (GD) and compliance with the therapy recommendations.

Article Synopsis
  • Between 30% and 60% of patients with thrombotic thrombocytopenic purpura (TTP) experience relapses, with a mortality rate of 15-20%. Rituximab, an anti-CD20 antibody, may help prevent these relapses.
  • A study involved 24 adult patients with acute TTP episodes who received daily plasma exchange and rituximab treatment; the medication was given weekly for a median of 13 days.
  • Results showed no severe side effects from rituximab, with 87.5% of patients achieving complete remission within 21 days and an overall high response rate during 30 months of follow-up.

Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by a low platelet count and bleeding, whose incidence is approximately 6.2 for each 100,000 adults per year. Intravenous immunoglobulins (IVIG) can be useful in patients with ITP to prevent bleeding or prior to surgery.

In POEMS syndrome the identification and biopsy of an osteosclerotic lesion or a lymph node typical of Castleman's disease (CD) is essential to establish the diagnosis and plan appropriate treatment. We report four patients in whom the localisation and identification of diagnostic bone lesions or lymphadenopathies were guided by fluorodeoxyglucose positron emission tomography integrated with computerised tomography (FDG PET/CT). FDG PET/CT identified bone lesions not detected with other techniques in one patient, and revealed hypermetabolic characteristics in bone lesions or adenopathies in the others, thus guiding the diagnostic biopsy in those with hypermetabolism.

Background And Aim: We show a descriptive study of a Rapid Diagnosis Unit as an alternative of the traditional hospital admission.

Material And Methods: An Internist, a Radiologist and a Nurse have constituted Rapid Diagnosis Unit. A retrospective and descriptive study of 1132 patients visited in the first and a half- year is described.

Background: Standard therapy with corticosteroids and cyclophosphamide followed by azathioprine has improved renal and patient survival in renal vasculitis. However, this regimen is associated with high toxicity. Mycophenolate mofetil (MMF), a less toxic immunosuppressive drug, has been proposed as a therapeutic alternative.

Background: Malabsorption syndrome often develops in patients with common variable immunodeficiency (CVID). Why structural damages appear in some CVID patients and not in others is not fully understood. Memory B cells (MBs) are responsible for the production of specific antibodies, and their defects have previously been related to autoimmune, granulomatous, and lymphoproliferative complications of CVID.

Article Synopsis
  • Cholesterol embolism (CE) is a growing but often overlooked medical issue where recognizing its clinical signs is crucial for accurate diagnosis.
  • A study of 26 male patients with CE, primarily aged 64, revealed that nearly all had multiple atherosclerosis risk factors, with skin lesions and renal failure being the most common symptoms; 58% of patients died, mostly due to pre-existing chronic renal failure.
  • The research highlights that CE is often misdiagnosed, with skin biopsies being a useful tool for confirmation, but the findings may not fully represent the broader population since the data was collected from a university hospital.
