Four serologically confirmed fatal cases of nephropathia epidemica (NE), the mild form of hemorrhagic fever with renal syndrome (HFRS) are described. All the patients had disseminated intravascular coagulation. Autopsies revealed hemorrhage and necrotic areas of their pituitary glands, myocarditis, venous congestion and hemorrhage of the kidneys as well as pulmonary edema and hemorrhage of the lungs in all patients. This report provides new evidence that NE can be a fatal disease.

Systemic inflammatory response syndrome (SIRS) is characterized by body temperature abnormalities, tachypnea or hyperventilation, tachycardia, and leukocytosis or leukopenia. Although it is typically associated with a serious infection and referred to as sepsis, SIRS can stem from noninfectious causes, as well. We report the cases of four patients with toxic serum levels of salicylate (33.5 to 67.6 mg/dL) and SIRS, and we discuss mechanisms responsible for SIRS. Our patients showed temperature disturbances (35.5 degrees C to 39.8 degrees C), noncardiogenic pulmonary edema, and mixed acid base disturbances. Other abnormalities included coagulopathy (disseminated intravascular coagulation), encephalopathy, and hypotension. All four patients recovered from SIRS, probably due to early recognition and treatment; only one patient did not survive the hospitalization. Chronic salicylate toxicity should be considered as a cause of SIRS in the absence of a source of infection, since survival appears to be dependent on prompt diagnosis and management.

Plasmapheresis, ultrafiltration of blood, and hemodialysis were effectively used in the treatment of a 20-year-old woman after cesarean section who was transfused 300 ml of wrong group blood. The resultant hemotransfusion conflict was characterized by shock, disseminated intravascular coagulation, hemolysis, acute pulmonary edema and renal failure. Plasmapheresis helped abolish the hemolysis. Pulmonary edema was eliminated by ultrafiltration of 2 liters of blood. Six sessions of hemodialysis administered within 10 days arrested renal insufficiency. The treatment administered may be considered as the method of choice in such patients.

Nineteen adolescent patients with eclampsia were studied in the course of 6 years. In 68% of the cases eclampsia (E) occurred antepartum, in 5% intrapartum. Maternal mortality was 52.65% (one patient with HELLP syndrome). Serious maternal morbidity included disseminated intravascular coagulations (10.52%), abruptio placentae (15.8%), pulmonary edema (5.26%) and acute renal failure (5.26%). Abruptio placentae was strongly correlated with the development of disseminated intravascular coagulation (p 0.0001), acute renal failure (p 0.001) and pulmonary edema (p 0.001). Eclampsia and HELLP syndrome were the most dangerous complications in adolescent pregnancies. They are associated with a serious maternal morbidity, especially when it arises in the postpartum period.

HELLP syndrome in the parturient (hemolysis, elevated liver enzymes, and low platelet count) is associated with poor maternal and fetal outcomes. Maternal mortality has been estimated to be as high as 24%. Patients with HELLP syndrome are also at greater risk of pulmonary edema, adult respiratory distress syndrome, abruptio placentae, disseminated intravascular coagulation, ruptured liver hematomas, and acute renal failure. Perinatal mortality is equally high, ranging from 79 to 367 per 1,000 live births, and neonatal complications correlate with the severity of maternal disease. Many clinicians view HELLP syndrome as an entity of preeclampsia, and because of varied symptomatology, the initial diagnosis may be obscured. Prodromal signs include: (1) weakness and fatigue, (2) nausea and vomiting, (3) right upper quadrant and/or epigastric pain, (4) headache, (5) changes in vision, (6) increased tendency to bleed from minor trauma, (7) jaundice, (8) diarrhea, and (9) shoulder or neck pain. Before delivery, aggressive obstetric management is directed toward stabilization of the affected organ systems, if possible, and timely interruption of the pregnancy in the early phase of the accelerated disease progression. Definitive therapy is delivery. Parturients with HELLP syndrome are often critically ill; their infants are frequently premature and their conditions are compromised. Management criteria should include a multidisciplinary approach in a tertiary care center. Obstetric anesthesia personnel should perform a thorough preanesthetic evaluation and be familiar with the pathophysiologic changes of this syndrome. Determining the anesthetic of choice depends on the patient's condition, fetal well-being, and the urgency of the situation. In the presence of severe coagulopathy, regional anesthesia is contraindicated.

Malaria remains an overwhelming problem in tropical developing countries, with 300 to 500 million new cases and 1.5 to 3.5 million deaths per year. Malaria is a potentially life-threatening disease for travelers to the tropics. Imported malaria is an important clinical problem in nonendemic areas of the world because of increasing numbers of travelers, overseas workers, and immigrants from endemic areas. According to the World Health Organization's criteria, the recognition of one or more of the following clinical features should raise the suspicion of severe malaria: cerebral malaria (unrousable coma), severe anemia (hemoglobin <5 g/dL), renal failure (serum creatinine >3 mg/dL), pulmonary edema or adult respiratory distress syndrome, hypoglycemia (glucose <40 mg/dL), circulatory collapse or shock, disseminated intravascular coagulation, repeated generalized convulsions, acidosis (pH <7.25), macroscopic hemoglobinuria, hyperparasitemia (>5 percent of the erythrocytes infested by parasites), or jaundice (bilirubin >3 mg/dL). Although only a small proportion of patients with malaria develops severe manifestations, these patients require the most urgent and intensive care. Mortality among patients with cerebral malaria, even when treated in modern intensive care units, exceeds 30%, and when complicated by the adult respiratory distress syndrome, it may approach 80%. Among travelers, mortality remains a serious issue because of failure to obtain and use preventive measures, delay in seeking medical attention, and misdiagnosis.

Six patients with severe and complicated falciparum malaria (6.7 +/- 2.7 WHO criteria) were admitted to our Intensive Care Unit. All patients acquired the disease while travelling in tropical Africa without appropriate chemoprophylaxis. The clinical manifestations included hyperpyrexia (all patients), chills (4), sweating (2), asthenia (3), anorexia (2), headache (1), arthralgias (1), vomiting (4), diarrhoea or abdominal discomfort (3), jaundice (2) and disturbances of consciousness (4). All patients had anemia, thrombocytopenia, hyponatremia, hypoproteinemia, hypoalbuminemia, hypocalcemia and acute renal failure, in one case associated with anuria. A low grade parasitemia was observed in two patients and a high grade parasitemia (20%-58% of erythrocytes) in four. Exchange transfusion was performed only in high parasitemic patients and all of them survived. All patients were treated with quinine, a sulfonamide and pyrimethamine. Additionally, five patients received oxytetracycline, doxycycline or clindamycin. Three patients required hemodyalisis. Five patients had delirium, coma or seizures. All patients had at least one sign of hepatic impairment: liver enlargement, jaundice or increased bilirubin or aminotransferase levels. Two patients had spleen enlargement. Laboratory findings suggested disseminated intravascular coagulation in four patients. Four patients developed pulmonary changes and three of them required mechanical ventilation. A Swan-Ganz catheter was placed in four patients. In three of them (two with pulmonary edema) the pulmonary capillary wedge pressure was initially increased, which suggested a cardiogenic or hypervolemia mechanism, but soon returned to normal level. One patient with low grade parasitemia died because of adult respiratory distress syndrome after 18 days. In our series, the degree of parasitemia was not related to the severity of the disease.

Septic adrenal hemorrhage is classically caused by meningococcemia. An autopsied case is presented of a 45-year-old man with adrenal hemorrhage due to Klebsiella oxytoca bacteremia following placement of a central venous catheter. He died 5 hours after developing disseminated intravascular coagulation (DIC). The bacterial entry site may have been the catheter. The cause of death was considered to be pulmonary edema due to bacteremia rather than adrenal insufficiency due to hemorrhage. Septic adrenal hemorrhage should be recognized as a subtype of sepsis rather than adrenal insufficiency, and may be caused in conditions of severe sepsis with DIC, independent of the microorganic variety.

Hantaviruses are RNA viruses that belong to the genus Hantavirus, family Bunyaviridae. The main reservoir of hantaviruses are rodents. Humans become infected by inhaling particles of dust contaminated with faeces of rodents, that are found In Europe and Asia hantaviruses named: Hantaan, Seoul and Dobrava-Belgrade causing haemorrhagic fever with renal syndrome (HFRS) are prevalent. Typical clinical picture of HFRS consists of renal insufficiency (primarily anuria and then polyuria with disturbances of water and electrolytic balance), hypotension, shock and disseminated intravascular coagulation and fibrynolisis (DIC). The mild form of this disease caused by Puumala virus is found in Scandinavia. North and South America are the regions where the prevalence of viruses: Sin Nombre, Black Creek Canal, Bayou, and New York causing hantavirus pulmonary syndrome (HPS) has been noted. In the course of this disease non-cardiogenic pulmonary oedema requires immediate hospitalisation at intensive care ward with artificial ventilation. Mortality in HPS due to hypotension, hypoxia and shock ranges up to 40%.

The complication of thrombotic thrombocytopenic purpura or hemolytic uremic syndrome (TTP/HUS) can occur in cancer patients. It is characterized by a microangiopathic hemolytic anemia, severe thrombocytopenia, and renal failure. Pulmonary manifestations, especially pulmonary edema, are a common observation. Neurologic changes are also frequently seen. The etiology is unknown at this time. It has been observed in many different types of cancer and is most commonly seen in gastric adenocarcinoma followed by carcinoma of the breast, colon, and small cell lung carcinoma. The hemolysis can be massive and is due to red cell fragmentation, as schistocytes are present in all the cases. Though immune complexes are present in the plasma, the antiglobulin (Coomb's) test is negative. Chemotherapeutic agents, especially mitomycin C, have been implicated as causative factors. There is a correlation of this complication with the cumulative dose. However, chemotherapy cannot account for all the cases as the syndrome can occur in untreated patients. It can be differentiated from disseminated intravascular coagulation by the absence of a coagulopathy. Management should consist of plasma exchange, use of a Staphylococcus aureus column (Prosorba), and control of hypertension. Because of the susceptibility to pulmonary edema, blood volume overloading should be avoided.
