Eclampsia is defined as the occurrence of seizures in pregnancy or within 10 days of delivery, accompanied by at least two of the following features documented within 24 hours of the seizure: hypertension, proteinuria, thrombocytopenia or raised aspartate amino transferase. Eclampsia complicates approximately one in 2,000 pregnancies in the United Kingdom and it remains one of the main causes of maternal death. Up to 38% of cases of eclampsia can occur without premonitory signs or symptoms of pre-eclampsia-that is, hypertension, proteinuria, and oedema. Only 38% of eclamptic seizures occur antepartum; 18% occur during labour and a further 44% occur postpartum. Rare cases of eclampsia have occurred over a week after delivery. Outcome is poor for mother and child. Almost one in 50 women suffering eclamptic seizures die, 23% will require ventilation and 35% will have at least one major complication including pulmonary oedema, renal failure, disseminated intravascular coagulation, HELLP syndrome, acute respiratory distress syndrome, stroke, or cardiac arrest. Stillbirth or neonatal death occurs in approximately one in 14 cases of eclampsia. Up to one third of eclamptic seizures occur out of hospital. For this reason, initial management may involve accident and emergency departments. Early involvement of senior obstetric staff is crucial. Optimal emergency management of seizures, hypertension, fluid balance and subsequent safe transfer is essential to minimise morbidity and mortality.

Trauma is the most common cause of death under the age of 45. Many trauma patients die of multiple organ failure, especially acute respiratory distress syndrome. The basic cause of traumatic shock has only partially been elucidated. Data resources include research papers on the subject of trauma and shock from 1875 to the present. These papers numbered more than 40,000. Almost all of the papers proposed that traumatic shock was due to hypovolemia. The concept of a shock toxin as promulgated during World War I is correct. This toxin is a thrombogenic aminophospholipid that occurs only on the inner layer of all cell membranes and is liberated by cell destruction. It causes disseminated intravascular coagulation, which may obstruct the microcirculation of any and all organs producing multiple organ failure by microclots. These microclots may be lysed by plasminogen activator and circulation to the organs restored.

Previous studies suggest that there is a systemic activation of clotting and fibrinolysis in preterm infants with advanced respiratory distress syndrome (RDS). However, there are no data on the hemostatic status in the early stages of the disease; therefore, we studied some of the hemostatic parameters in these patients and made several studies at different times in preterm infants who did or did not develop RDS, using similar protocols. We found normal plasma fibrinogen, protein C, protein S, C4b-binding protein, thrombomodulin, antithrombin III, thrombin-antithrombin III complex, prothrombin fragment 1.2, plasminogen, tissue plasminogen activator, alpha-1 antitrypsin, alpha-2-macroglobulin and protein Z. However, lower D-dimer and higher plasminogen activator inhibitor and von Willebrand factor antigen levels were found within six hours of life in infants who later developed RDS compared to the control group. These findings suggest that disseminated intravascular coagulation is not prominent in the early stages of RDS. Moreover, reduced D-dimer and increased plasminogen activator inhibitor and von Willebrand factor antigen levels are probably related to the abnormalities in the fibrinolytic mechanism due to lung damage in RDS, but further studies are needed to show their pathogenic significance in RDS.

Hypovolemia, hypothermia, and hypotension are common postoperative findings that predispose the critically ill patient to secondary complications. This patient population is especially vulnerable to sepsis, hypoxia, and immune dysfunction. Careful monitoring is essential for early recognition of potentially life-threatening physiologic derangements. Early and aggressive intervention may help minimize systemic insult before it progresses to acute respiratory distress syndrome, acute renal failure, disseminated intravascular coagulation, or multiple organ failure.

In this report, we describe three patients with pulmonary tuberculosis with acute respiratory failure with an extensive tuberculous consolidation in bilateral lung fields. Disseminated intravascular coagulation (DIC) was present in one patient and miliary tuberculosis in two patients. They all developed acute respiratory distress syndrome (ARDS), nessecitating management by mechanical ventilation with a combination therapy of antituberculous agents and methylprednisolone (m-PSL) pulse therapy. Only one patient survived in whom the PaO2/FiO2 ratio recovered rapidly after the initiation of therapy. Two patients whose systemic condition upon admission was critically ill eventually died of hepatic failure and bacterial pneumonia, even though ARDS and pulmonary tuberculosis were successfully treated. Prognosis of pulmonary tuberculosis complicating ARDS and DIC is poor, and these patients need systemic intensive treatment, in which m-PSL therapy may be beneficial.

The view of the endothelium as a passive barrier has gradually changed as a number of endothelium-derived substances have been discovered. Substances like nitric oxide, prostaglandins and endothelins have potent and important properties, involving not only the circulation as such but also the response to stimuli like inflammation and trauma. The endothelin system, discovered in 1988, has not only strong vasoconstrictor properties, but also immunomodulating, endocrinological and neurological effects exerted through at least two types of receptors. Septic shock, a condition with high mortality, is associated with vast cardiovascular changes, organ dysfunction with microcirculatory disturbances and dysoxia. In the experimental setting, endotoxaemia resembles these changes and is, as well as septic shock, accompanied by a pronounced increase in plasma endothelin levels. The pathophysiology in septic and endotoxin shock remains to be fully elucidated, but several studies indicate that endothelial dysfunction is one contributing mechanism. Activation of the endothelin system is associated with several pathological conditions complicating septic shock, such as acute respiratory distress syndrome, cardiac dysfunction, splanchnic hypoperfusion and disseminated intravascular coagulation. Through the development of both selective and nonselective endothelin receptor antagonists, the endothelin system has been the object of a large number of studies during the last decade. This review highlights systematically the findings of previous studies in the area. It provides strong indications that the endothelin system, apart from being a marker of vascular injury, is directly involved in the pathophysiology of septic and endotoxin shock. Interventions with endothelin receptor antagonists during septic and endotoxin shock have so far only been done in animal studies but the results are interesting and promising.

We report a transient type I factor VIII inhibitor that arose in a 30-year-old hemophilia patient just after staphylococcal septicemia. This situation usually occurs early in the course of substitution therapy with factor VIII concentrate in hemophilia patients. Although disseminated intravascular coagulation and acute respiratory distress syndrome developed after septic shock, the patient recovered following intravenous administration of antibiotics (meropenem and gentamycin), an antithrombin preparation, high-dose methylprednisolone, and recombinant factor VIII concentrate (rFVIII). During this therapy, however, activated partial thromboplastin time gradually lengthened. On the seventh day of hospitalization, intracranial hemorrhage occurred with right hemiplegia, even though the substitution therapy had continued at the same dosage (30 U/kg per day) of rFVIII. At that point, 4 Bethesda units of the type I inhibitor against factor VIII were detected in the plasma. Increased amounts (46 U/kg per day) of rFVIII and prednisolone were administered, and hypothermic therapy was initiated. Following these treatments, the patient's general condition gradually improved, and within 25 days the inhibitor titer dropped to undetectable levels and did not recur during treatment. These clinical findings suggest that the staphylococcal septic shock may have acted as a trigger in the development of transient factor VIII inhibitor in this patient.

Sepsis and septic shock constitute an important cause of morbidity and mortality in critically ill children. Thus, the systemic response to infection and its management remains a major challenge in clinical medicine. Apart from antibiotic administration, the majority of available therapies are limited to supportive strategies, although considerable efforts are being undertaken to devise innovative approaches that modulate host inflammatory responses. In suspected sepsis, 2 or 3 days' empiric antibiotic therapy should begin immediately after cultures have been obtained without awaiting results. Antibiotics should be re-evaluated when the results of the cultures and susceptibility tests are available. The initial antibiotic (combination) is determined by the likely causative agent, susceptibility patterns within a specific institution, CNS penetration, toxicity, and the patient's hepatic and renal function. The likely offending micro-organism in turn depends primarily on the patient's age, coexistence of any premorbid condition leading to impaired immune response, and the presenting signs and symptoms. Close attention to cardiovascular, respiratory, fluid and electrolyte, haematological, renal and metabolic/nutritional support is essential to optimise outcome. Fluid resuscitation is of utmost importance to overcome hypovolaemia on the basis of a diffuse capillary leak. Monitoring and normalisation of the heart rate is essential. In case of nonresponse to fluid resuscitation, inotropic and vasoactive agents are commonly used to increase cardiac output, maintain adequate blood pressure and enhance oxygen delivery to the tissue. Because respiratory distress syndrome is seen in about 40% of critically ill children with septic shock, increased inspired oxygen is essential. To provide optimal relief from respiratory muscle fatigue and facilitate the provision of positive airway pressure, early intubation and mechanical ventilation should be considered. Renal support is essential to avoid prolonged renal shutdown in hypoperfusion states. Haematological support comprises replacement therapy of clotting factors to overcome disseminated intravascular coagulation. Metabolic support may include glucose support, extraction of ammonia from the body and recognition of liver dysfunction. Nutritional support may modify the inflammatory host response, and early enteral feeding can improve outcome in critical illness. To date, glucocorticoid and non-glucocorticoid anti-inflammatory agents have not shown significant benefit in septic patients.

A 56-year-old Japanese male was admitted to Toyohashi Municipal Hospital because of fever, cough, and dyspnea. Chest X-ray film showed bilateral alveolar infiltrates. He suffered from severe hypoxemia and was given a diagnosis of acute respiratory distress syndrome. He was also complicated with disseminated intravascular coagulation and pseudomembranous colitis. He fully recovered by intensive treatment with antibiotics, mechanical ventilation and endotoxin eliminating therapy. Legionella longbeachae was isolated from his respiratory specimens and was regarded as the etiologic agent of his pneumonia.

A 64-year-old woman, who was previously in good health was admitted because of progressive respiratory distress. Her chest radiograph revealed bilateral widespread alveolar infiltrates. She was given a diagnosis of pneumonia caused by Mycoplasma pneumoniae serologically, acute respiratory distress syndrome, and disseminated intravascular coagulation. She died of multiple organ failure despite intensive therapy with mechanical ventilation, intravenous erythromycin and corticosteroids, continuous hemodiafiltration, and plasma exchange. Although Mycoplasma pneumoniae infection is usually a benign self-limited disease, this case emphasizes its potentially serious nature even in normal healthy individuals.
