ABSTRACT
The use of social media and social networks has increased significantly in recent years. They are becoming progressively more important as information channels in private and professional contexts. Also, in medicine, social media are already being used in a variety of ways. For example, professional societies and patient interest groups are being increasingly represented in social networks. The broad use and wide audience of these networks offer new opportunities for the field of rheumatology. This review article provides an overview of the characteristics of some major social media platforms and systematically analyses the existing publications in the context of rheumatology. Furthermore, advantages, but also potential risks that may arise due to social media use are being addressed.

Colchicine, the toxin of the autumn crocus, has various anti-inflammatory effects. For this reason, it is being used for the treatment of several autoinflammatory diseases, such as gout or familial Mediterranean fever (FMF). In addition, some interesting studies have been published which suggest the benefits of colchicine in cardiovascular diseases. Furthermore, various anti-inflammatory therapeutic approaches are currently being tested in clinical trials for the treatment of COVID-19. First publications suggest a potential benefit of colchicine in certain disease phases of the virus infection. This article provides an overview of the mechanisms of action, benefits and side effects as well as the various possible uses of colchicine in rheumatology. Furthermore, a brief preview of potential new areas for use of the drug, which are also of interest to rheumatologists, are presented.

Pericarditis is the term for inflammatory involvement of the pericardium, which can be associated with pericardial effusion and myocardial involvement (perimyocarditis). Pericarditis can be present in the context of systemic inflammatory rheumatic diseases but can also constitute a distinct disease entity. Idiopathic recurrent pericarditis (IRP) describes relapsing conditions of pericarditis with an unknown cause, which show essential common features with autoinflammatory diseases. This article gives an overview of the frequency of pericarditis in systemic rheumatic diseases. Moreover, the clinical manifestations and pathophysiology of IRP are discussed. Finally, the therapeutic algorithms for acute and idiopathic pericarditis are explained.

The increasing use of smartphones is accompanied by a significant increase in the use of mobile applications (apps). Chronically ill patients could permanently profit from this development.This development is fuelled by the Digital Healthcare Act (DVG), whereby patients have a legal claim to certain apps, so-called digital health applications (DiGAs), which are reimbursed by the statutory health insurance companies. Especially in the field of rheumatology, there are various opportunities to implement apps in the management of chronic diseases and their comorbidities. Furthermore, rheumatic patients and rheumatologists are becoming interested in apps and are willing to use them in the daily routine. This article tries to shed light on the chances and risks of apps and gives a first insight into the digital landscape of rheumatology apps in Germany.

Based on the case of a 33-year-old female patient with Löfgren's syndrome and skin changes in the region of a tattoo, this article describes tattoo sarcoidosis as a special manifestation of cutaneous sarcoidosis. Papulonodular changes that are strictly confined to a tattoo are highly suspicious for tattoo sarcoidosis. Interestingly, tattoo sarcoidosis is commonly associated with the involvement of other organs.

BACKGROUND: Myalgia is a common but unspecific set of symptoms that may be caused by orthopedic, neurological and internal medical conditions, often resulting in a diagnostic challenge. Muscular polyarteritis nodosa (PAN) is a rare differential diagnosis of myalgia with elevated serological inflammatory markers. OBJECTIVE: Based on three clinical cases and the literature this review describes the essential clinical and diagnostic features of muscular PAN. RESULTS: Muscular PAN typically presents with immobilizing myalgia confined to the lower limbs and elevated serological inflammatory markers but often normal creatine kinase (CK) levels. Contrast-enhanced magnetic resonance imaging of the affected muscles, which can often mimic myositis, and muscle biopsy provide the relevant histological findings that lead to the diagnosis of a vasculitis. CONCLUSION: With respect to own experiences and the reviewed literature, muscular PAN should be considered as a possible diagnosis in cases of myalgia with elevated inflammatory markers but normal CK levels and a lack of further symptoms typical for vasculitis.

A novel in situ product recovery (ISPR) approach for the (fully) integrated separation of L-phenylalanine (L-phe) from a 20 l fed-batch process with the recombinant L-tyrosine auxotrophic strain E. coli F-4/pF81 is presented. The strain was rationally constructed for the production of the aromatic amino acid. Glucose and tyrosine control is used. A reactive extraction system consisting of kerosene, the cation-selective carrier D(2)EHPA and sulphuric acid, all circulating in liquid-liquid centrifuges, is applied for the on-line L-phe separation from cell- and protein-free permeate. Permeate is drained off from the bioreactor bypass. Using the novel ISPR approach, a significantly extended product formation period at 0.25 mmol/(g*h) together with a reduced by-product formation and a 28% relative glucose/L-phe yield increase is observed. Thus, the ISPR approach is superior to the reference non-ISPR process and even offers extraction rates approximately three times higher than the published membrane-based process.
