Thrombotic thrombocytopenic purpura is a rare, threatening disease characterized by thrombocytopenia, microangiopathic haemolytic anaemia and organ dysfunction, e.g., neurological impairment and renal insufficiency. We describe a patient with neurological impairment mimicking a meningoencephalitis in whom a thorough clinical evaluation along with appropriate laboratory tests led us to identify an underlying thrombotic thrombocytopenic purpura. The successful outcome of this patient was based on plasma exchange and immunosuppressive treatment. Thrombotic thrombocytopenic purpura should be considered in the differential diagnosis of patients presenting with any neurological abnormalities, anaemia and unexplained thrombocytopenia.

In experimental bacterial meningitis, adjunctive steroid treatment reduces the inflammatory response in the cerebrospinal fluid and subarachnoidal space, thereby improving neurological outcome. The clinical application of this concept was sustained by the European Dexamethasone Study which showed a beneficial effect of dexamethasone on neurological outcome and mortality in adult patients with bacterial--in particular S. pneumoniae-- meningitis. ⋯ Moreover, dexamethasone may have detrimental effects with regard to antibiotic efficacy and late severe neurological complications. Until further data about steroid use in bacterial meningitis becomes available, we propose that dexamethasone therapy in this setting should be abandoned.

Necrotizing fasciitis is rarely caused by Pasteurella multocida, a facultative anaerobic gram-negative coccobacillus found in the flora of the oro-gastrointestinal tract of many animals. We describe a rare case with overwhelming septicaemia resulting in multiple organ failure.

The abdominal compartment syndrome (ACS) refers to organ dysfunction that may occur as a result of increased intra-abdominal pressure (IAP). Successful management may require abdominal decompression and temporary abdominal closure (TAC). The aim of this study was to analyze the characteristics of patients requiring abdominal decompression, to describe the methods used for TAC, and to study the outcome of these patients. ⋯ Decompressive Laparotomy was effective in reducing IAP and was associated with an improvement in organ function. In most of the patients, the abdomen could not be closed after decompression, and fascial repair was delayed.

Sepsis and septic shock: pathophysiological and cardiovascular background as basis for therapy.
Sepsis and septic shock are common causes for admission to intensive care units. The morbidity and mortality remain unacceptably high despite the advanced treatments. ⋯ Further studies are needed to distinguish the importance of these various mechanisms. We recommend that further investigational work should focus on the recovery of the mitochondria-related bio-energetic shut down as the mitochondria could play a key role in the understanding of apoptosis and protective measures. Understanding the pathophysiology of sepsis and septic shock will inevitably lead to a more accurate treatment of these still too often fatal syndromes.
