Localized scleroderma (LoS) is a very heterogeneous connective tissue disease characterized by progressive sclerosis of the skin with possible involvement of extracutaneous structures. Both children and adults can be affected but show different frequencies for the individual subtypes of the disease. The clinical heterogeneity has already caused several modifications of existing classification criteria. Patients suffering from LoS can essentially be subdivided into five different subsets, which are defined by the horizontal and vertical extent of the tissue involvement. The quality of life of these patients is significantly impaired depending on the extent of the cutaneous and subcutaneous involvement. A causal treatment does not yet exist; however, patients should be treated with the currently available medications for progressive subtypes during the early phase of inflammation to reduce or avoid severe, cosmetic and functional impairments. Lichen sclerosus (LS) usually affects the genital as well as extragenital skin and both children and adults can be affected. This article focuses on the extragenital LS, which occurs more frequently in adults. The cause of the disease as well as causal treatment strategies are still lacking. Currently, treatment is adapted to the therapeutic strategies for LoS.

Einleitung: Eine Anämie wird häufig bei Patienten mit entzündlich-rheumatischen Erkrankungen beobachtet, wobei es bisher wenige Daten zum Vorkommen bei Patienten mit systemischer Sklerose (SSc) gibt. Das Ziel dieser Studie war es, die Häufigkeit einer Anämie und damit verbundener[zum vollständigen Text gelangen Sie über die oben angegebene URL], 44.

Systemic sclerosis (SSc) is a rare, chronic inflammatory autoimmune disease with unknown etiology, which leads to deposition of collagen and extracellular matrix proteins in the skin and affected internal organs. The diagnosis of SSc is based on clinical, serological, and paraclinical examinations. In 2013 new criteria for the classification of systemic sclerosis, which also take early forms of SSc into consideration, were developed. A complete clinical and paraclinical examination is important for the oligosymptomatic early stages and the subsequent disease course of SSc in order to diagnose and timely treat a developing organ involvement.

Digital ulcers (DU's) are one of the main symptoms of systemic scleroderma and occur in approximately 60% of all scleroderma patients. Due to possible complications such as infections, gangrene or amputation, they require regular medical attention and a good wound treatment by doctors and nursing staff. A definition of DU's has not yet been established. In 2009 the European League Against Rheumatism (EULAR) published guidelines for the treatment of DU's. An improvement of the healing of active ulcers has been described with Iloprost. Bosentan significantly reduced the frequency of occurrence of new DU's. In some small studies PDE-5 inhibitors appear helpful. Further studies with other therapeutic approaches will follow in the next few years.

Raynaud's phenomenon (RP) is characterized by repeated vasospastic attacks of the distal extremities induced by cold, humidity, vibrations or emotional stress. It typically presents a triphasic colour change from white (palor; vasoconstriction) to blue (cyanosis) and red (reactive hyperaemia). The symptoms are based on a primary RP in 90 %. Secondary RP is a symptom of an underlying disease. RP has to be distinguished from other colour changes of the distal extremities like acrocyanosis, erythromelalgia, perniosis and Chilblain-Lupus. Patients history, clinical examination, ANA, ESR/CRP and nailfold capillaroscopy are essential for the early diagnosis of an underlying disease. The initiation of angiologic tests is important in patients with digital ulcers, necrosis or gangrene. Important differential diagnoses in secondary RP are autoimmune rheumatic diseases like systemic sclerosis and systemic lupus erythematodes as well as vascular diseases like arterial occlusions and compression syndromes or concomitant medication (i. e. beta-blocker).

The diagnosis and therapy of systemic sclerosis (SSc) is demanding due to its nature as a multisystem disease and its chronic, severe course. To date, there are no generally accepted recommendations for diagnostic work-up either for the time of initial disease diagnosis or for the regular follow-up clinical examinations and diagnostic procedures required. However, due to recent advances, e.g. in the therapy of pulmonary arterial hypertension, regular examinations may contribute to early recognition and treatment of developing organ involvement. This manuscript describes the recommendations for initial and follow-up organ-specific clinical examinations and diagnostic work-up as compiled and carried out by the German Network for Systemic Scleroderma [Deutsche Netzwerk für systemische Sklerodermie (DNSS)].

Systemic scleroderma (SSc) is a rare, heterogenous, multisystem disease affecting different organ systems and therefore requires interdisciplinary management and patient care. The German Network for Systemic Scleroderma, funded by the country's Federal Ministry of Education and Research, was established 3 years ago and comprises dermatologists, rheumatologists, pulmonologists, and nephrologists from more than 40 medical centers. The registry contains data of more than 1800 patients. Analysis of the continually growing body of data will form the basis for the development of standardized recommendations for diagnosis and treatment of SSc.
