Cryoglobulins are immunoglobulins that precipitate in vitro at temperatures below 37 ̊C. Cryoglobulin-associated disease is heterogeneous, as not all patients present with it, includes various syndromic presentations (vasculitis is the most common, hyperviscosity syndrome is more exceptional), and can be associated with acute clinical pictures with high mortality. ⋯ Treatment should be modulated according to the predominant etiopathogenesis (vasculitis or hyperviscosity), the severity of internal organ involvement and, especially, the associated underlying disease. Due to the complex aetiological, clinical and pathological scenario of cryoglobulinaemia, early recognition of the most common clinical presentations, a comprehensive clinical assessment of the different organs that may be affected, and multidisciplinary work led by a unit specialised in systemic autoimmune diseases is essential.

Case Reports
The clinical relevance of inhalation technique in chronic obstructive pulmonary disease patients.
Numerous studies show that patients with chronic obstructive pulmonary disease (COPD) perform an incorrect inhalation technique (IT). This research aims to describe inhalation errors committed and their clinical importance, and to identify factors related to them. ⋯ Soaring incorrect technique rate, whose most common errors sparingly compromise the drug effectiveness. These errors are related to the way the patients perform the IT, and not to the difficulty in handling the device. This information demonstrates the relevance of training patients in a proper way.
