Modeling a complex disease: Multiple sclerosis—Update 2020
2021
Multiple sclerosis (MS) is a complex inflammatory disease of the central nervous system (CNS) with an unknown etiology. Thereby, MS is not a uniform disease but rather represents a spectrum of disorders, where each aspect needs to be modeled with specific requirements-for a systematic overview see our previous issue of this review (Kurschus, Wortge, & Waisman, 2011). However, there is broad consensus about the critical involvement of the immune system in the disease pathogenesis. To better understand how the immune system contributes to CNS autoimmunity, the model of experimental autoimmune encephalomyelitis (EAE) was developed. EAE can be induced in susceptible animals in many different wa…
Visualizing cell death in experimental focal cerebral ischemia: promises, problems, and perspectives
2011
One of the hallmarks of stroke pathophysiology is the widespread death of many different types of brain cells. As our understanding of the complex disease that is stroke has grown, it is now generally accepted that various different mechanisms can result in cell damage and eventual death. A plethora of techniques is available to identify various pathological features of cell death in stroke; each has its own drawbacks and pitfalls, and most are unable to distinguish between different types of cell death, which partially explains the widespread misuse of many terms. The purpose of this review is to summarize the standard histopathological and immunohistochemical techniques used to identify …
CLEFT PALATE ONLY: CURRENT CONCEPTS
2017
Cleft palate only (CPO) is one of the most common congenital malformations worldwide. The etiopathogenesis of CPO is not completely understood. Environmental factors, such as smoking, alcohol consumption, intake of drugs during pregnancy, advanced paternal age, have been demonstrated to be a risk of CPO, but conflicting results have also been published. Insufficient intake of folic acid during the pregnancy has been suggested to increase the risk for CPO. The demonstrated risk for siblings and the higher risk for monozygotic twins suggest a genetic etiopathogenesis for CPO. In some cases of CPO a prevalent mode of inheritance has been reported, but oligogenic models with reduced penetrance,…
Two pathways, one patient; UK asthma guidelines
2018
The first widely disseminated ‘asthma guideline’ came out of Australia and New Zealand in 1989,1 followed shortly by the British Thoracic Society (BTS) in 1990,2 the United States National Heart, Lung, and Blood Institute Expert Panel Report in 19913 and the Global Initiative for Asthma (GINA) strategy document in 1995.4 All have benefited from regular updates, the BTS collaborating with the Scottish Intercollegiate Guideline Network (SIGN) since 2003, most recently in 2016.5 Each new iteration of the asthma guidelines was written by experts in the field and based on best available evidence. It is not known whether these guidelines (or any others) have improved the care of people with asthm…
European Association for the Study of the Liver Hepatocellular Carcinoma summit 2014: old questions, new (or few) answers?
2014
, the European Association for the Study of the Liver (EASL) organized the 2014 EASL HCC Summit in Geneva, Switzerland from 13 to 16 February 2014. A number of interesting issues on the management of hepatocellular carci-noma (HCC) have been addressed during this meeting. However, our feeling is that only few answers have been given to those questions, mainly because of the still poor knowledge of the molecular basis and the natural history of HCC.HCC is a complex disease, associated in the wide majority of cases with under -lying cirrhosis. In addition, HCC pre-sents with high heterogeneity
Number VII Behcet's disease (Adamantiades syndrome)
2006
Behçet's syndrome (BS; Adamantiades syndrome) is the association of the triple symptom complex of recurrent aphthous stomatitis (RAS) with genital ulceration, and eye disease (especially iridocyclitis) though a number of other systemic manifestations may also be seen. BS mainly affects young adult males, and there is an association with HLA-B5 and HLA-B51 (B5101). Features such as arthralgia and leucocytoclastic vasculitis suggest an immune-complex mediated basis, which is supported by finding circulating immune complexes and, although the antigen responsible is unidentified, heat shock proteins have been implicated. An inflammatory disorder, BS is now considered as a systemic vasculitis, c…
ECTRIMS/EAN guideline on the pharmacological treatment of people with multiple sclerosis.
2018
Background and purpose: Multiple sclerosis (MS) is a complex disease of the central nervous system. As new drugs are becoming available, knowledge on diagnosis and treatment must continuously evolve. There is therefore a need for a reference tool compiling current data on benefit and safety, to aid professionals in treatment decisions and use of resources across Europe. The European Committee of Treatment and Research in Multiple Sclerosis (ECTRIMS) and the European Academy of Neurology (EAN) have joined forces to meet this need. The objective was to develop an evidence-based clinical practice guideline for the pharmacological treatment of people with MS to guide healthcare professionals in…
Mortality studies for multiple sclerosis: still a useful tool to analyse long-term outcome
2017
Mortality studies represent a useful way to look at the prognosis of a chronic complex disease and to evaluate the impact of therapeutic and caring strategies on long-term outcomes. Results should be interpreted keeping always in mind the following important aspects: first, to what extent the disease affects patient’s life in terms of life expectancy. Second, what is at this moment the real impact that the strategies and measures we adopt to cure and to take care of patients really have on clear and strong endpoints like mortality? In their JNNP manuscript, Lunde et al .1 show a significant reduction in life expectancy in people affected by multiple sclerosis (MS) over a study period of abo…
