The multiple myeloma (MM) has an incidence of 3-4/100,000 in the Caucasian population. MM has to be distinguished from smouldering MM and monoclonal gammopathy of uncertain significance (MGUS). In younger patients (<65 years) a good long-term remission is the aim of therapy, while in the elderly patients with comorbidities the aim is a good partial remission with good quality of life. ⋯ High-dose chemotherapy, often as a tandem transplantation, is part of standard therapy of MM patients <65 years. However, allogeneic stem cell transplantation is the only curative approach. New substances approved for treatment of relapsed MM include bortezomib, thalidomide, and lenalidomide.

The introduction of Drug Eluting Stents was an important step to reduce restenosis rate after coronary stent implantation. Unfortunately, reduction of restenosis was paid off by the price of potential increased late (>30 days) stent thrombosis. However, current data are not completely conclusive with respect to extent and duration of stent thrombosis and cardiovascular risk after drug eluting stent implantation. ⋯ However in selected high-risk patients (e.g. left main or multivessel stent implantation) control angiography may be useful. Medical therapy of risk factors (hyperlipidemia, hypertension, and diabetes mellitus) is essential also after coronary stent implantation. It is important to screen patients for diabetes mellitus, since approximately 1/3 of patients after coronary intervention have an otherwise unrecognized diabetes mellitus or glucose tolerance disturbance.

Immunoglobulin is a blood product prepared from the plasma of healthy donors. The therapeutic use of polyvalent immunoglobulins is an established therapy in primary antibody deficiencies, in idiopathic thrombocytopenic purpura (ITP) and in Guillain-Barré syndrome. ⋯ The paper presented here critically discusses the modern studies investigating the use of immunoglobulins in different diseases. The main focus is the use of immunoglobulins in patients with sepsis or septic shock.

Case Reports
[Acute thrombo-embolic elevated ST infarct in a patient with essential thrombocytosis].
A 48-year-old man presented with acute chest pain and a greatly increased platelet count. Emergency coronary angiographic revealed thrombotic occlusion of the right coronary artery. ⋯ Due to inadequate postinterventional platelet inhibition an intensified dual antiplatelet therapy with acetylsalicylic acid (ASS) and clopidogrel was applied to prevent stent thrombosis. Due to the thrombo-embolic complication and a platelet count over 1 million/microl a cytoreductive treatment with hydroxyurea was initiated.

A concept for combined enteral and parenteral nutrition for critically ill patients is described in which endogenous substrate production during the acute phase of illness is taken into consideration and hyperalimentation is avoided. The nutritional goal is defined by multiplication of the base rate, i.e. body weight (BW) in kg as delivery rate in ml/h (wedge 24 kcal/kg BW/24 h), with a target factor, which varies between 0.2 and 1.8. An equivalent composition of enteral and parenteral nutrition allows a transition between both forms without problems. Simultaneously, immunologic aspects of nutrition are considered as well and both forms of nutrition are complemented by immune-modulating substrates such as glutamine and antioxidants.
