Recommendations for Fluid Resuscitation in Acutely Ill Patients

Although the use of resuscitation fluids is one of the most common interventions in medicine, no currently available resuscitation fluid can be considered to be ideal. In light of recent high quality evidence, a reappraisal of how resuscitation fluids are used in acutely ill patients is now required. The selection, timing, and doses of intravenous fluids should be evaluated as carefully as they are in the case of any other intravenous drug, with the aim of maximizing efficacy and minimizing iatrogenic toxicity.

Diagnostic Criteria for Dementia with Lewy Bodies (DLB)

Synucleinopathies, with and without dementia, encompass a wide range of diseases including Parkinson’s disease, multiple system atrophy, rapid eye movement (REM) sleep behavior disorder, and dementia with Lewy bodies (DLB). DLB is a neurodegenerative disorder resulting in slowly progressive and unrelenting dementia until death.

Classification and Clinico-Pathological Characteristics of Different Cryoglobulinemias

Cryoglobulinemia is usually classified into three subgroups according to Ig composition: type I cryoglobulinemia is composed of only one isotype or subclass of immunoglobulin. Both type II and type III mixed cryoglobulins are immune complexes composed of polyclonal IgGs, the autoantigens, and mono- or polyclonal IgMs, respectively; the IgMs are the corresponding autoantibodies with rheumatoid factor (RF) activity.

Features and Treatment of the Inherited Primary Hyperoxalurias

The autosomal recessive inherited primary hyperoxalurias types I, II and III are caused by defects in glyoxylate metabolism that lead to the endogenous overproduction of oxalate.

Indications for Antiviral Treatment in Patients with Herpes Zoster

Primary infection with varicella–zoster virus (VZV) results in chickenpox, characterized by viremia with a diffuse rash and seeding of multiple sensory ganglia, where the virus establishes lifelong latency. Herpes zoster is caused by reactivation of latent VZV in cranial-nerve or dorsal-root ganglia, with spread of the virus along the sensory nerve to the dermatome.

Intravenous Immune Globulin in Autoimmune and Inflammatory Diseases

Initially used for the treatment of immunodeficiencies, intravenous immunoglobulins (IVIg) have increasingly been used as immunomodulatory agent in autoimmune and inflammatory disorders. The mode of action of IVIg is enigmatic, probably involving Fc-dependent and/or F(ab’)2-dependent non-exclusive mechanisms of action. IVIg broadly interacts with the different components of the immune system: cytokines, complement, Fc receptors and several cell surface immunocompetent molecules. IVIg also has an impact on effector functions of immune cells. These mechanisms of action of IVIg reflect the importance of natural antibodies in the maintenance of immune homeostasis.

Modified Marsh Classification of Histologic Findings in Celiac Disease (Oberhuber)

Celiac disease is a systemic immune-mediated disorder triggered by dietary gluten in genetically susceptible persons. Gluten is a protein complex found in wheat, rye, and barley. Celiac disease is characterized by a broad range of clinical presentations, a specific serum autoantibody response, and variable damage to the small intestinal mucosa.

Diagnostic Criteria for Chronic HBV Infection

Chronic HBV infection is a necroinflammatory disease of the liver caused by persistent infection with HBV, and can be categorized as hepatitis B e antigen (HBeAg) positive or negative. Inactive hepatitis B surface antigen (HBsAg) carriers have HBV infection of the liver without significant, ongoing necroinflammatory disease. HBV infection is resolved when there is no further virologic, biochemical, or histologic evidence of active viral infection or disease.
