Eight cases of ecstasy related acute liver damage referred to a specialised liver unit are described. Two patients presented after collapse within six hours of ecstasy ingestion with hyperthermia, hypotension, fitting, and subsequently disseminated intravascular coagulation with rhabdomyolysis together with biochemical evidence of severe hepatic damage. One patient recovered and the other with evidence of hyperacute liver failure was transplanted but subsequently died, histological examination showing widespread microvesicular fatty change. Four patients presented with acute liver failure without hyperthermia. All four fulfilled criteria for transplantation, one died before a donor organ became available, and two died within one month post-transplantation of overwhelming sepsis. Histological examination showed submassive lobular collapse. Two patients presented with abdominal pain and jaundice and recovered over a period of three weeks; histological examination showed a lobular hepatitis with cholestasis. Patients developing jaundice or with evidence of hepatic failure particularly encephalopathy and prolongation of the international normalised ratio, or both, whether or not preceded by hyperthermia, should be referred to a specialised liver unit as liver transplantation probably provides the only chance of recovery.

Although rare, exertional collapse and sudden death are the most serious potential complications of sickle cell trait. Studies suggest that this condition may occur in susceptible persons when poor physical conditioning, dehydration, heat stress or hypoxic states precipitate sickling of the abnormal erythrocytes. Sickling leads to endothelial damage, which can cause vasoconstriction, disseminated intravascular coagulation and local tissue damage. Cardiac effects include acute ischemia and arrhythmias. Muscle damage results in acute compartment syndromes and release of myoglobin into the circulation. Acute renal failure is possible. Diagnosis is based on a high index of suspicion, and characteristic presentation and laboratory findings, including myoglobinuria, hyperkalemia, hypocalcemia, hyperphosphatemia and elevated creatine kinase levels. The differential diagnosis includes pulmonary embolism, acute cardiac events, anaphylaxis and heat stroke. Management is based on stabilization, rehydration, and the treatment and prevention of complications.

"Designer drugs" are derivatives of approved drugs abused for recreational effect and created by underground laboratories to circumvent legal restriction. By far the most controversial drug has been MDMA (3,4-methylenedioxymethamphetamine) and the newer derivative MDEA (3,4-methylenedioxymethamphetamine) often called "Eve". MDEA-related deaths have not been reported in the US, but there have been a death of MDMA and MDEA severe poisonings. Convulsions, collapse, hyperpyrexia, disseminated intravascular coagulation rhabdomyolysis, and acute liver and renal damage result from the ingestion of the drug. Complications may occur and severity and death possibly result. The case of a 31-y-old male, the first victim of MDEA in Greece, is reported. Blood MDEA was 3.1 micrograms/mL; MDEA concentrations in liver, lung and kidney were 4.8, 5.2, and 4.8 micrograms/g respectively.

Purpura fulminans is a devastating disorder characterized by rapidly progressing hemorrhagic necrosis of the skin, vascular collapse, and disseminated intravascular coagulation. It is most often seen in children, and it is usually preceded by meningococcemia or another infection. Most often, the disorder results in severe skin loss, but it can also result in the need for extremity amputations. In extreme cases, wound coverage after excision may be problematic because of the limited existence of donor sites and the need for amputation revisions. The case of a 21/2-year-old male requiring amputations of all four extremities due to severe purpura fulminans is presented to illustrate the use of Integra Artificial Skin (Integra Lifesciences Corp., Plainsboro, NJ) to obtain immediate wound closure. Integra Artificial Skin is a bilayered skin substitute that engrafts to a viable wound bed. In the case presented here, where the viability of the underlying tissue of the amputated stumps was questionable, the artificial skin acted as an indicator of that viability. It engrafted well onto the upper extremity stumps, which were of excellent viability, but it needed to be replaced on the lower extremity stumps, which required further debridement and amputation revisions. The use of artificial skin spared the patient the immediate use of his limited and valuable autograft sites. In conclusion, Integra Artificial Skin can be a useful adjunct in the treatment of severe purpura fulminans that includes skin and extremity necrosis.

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.

We describe five patients with complications following amphetamine overdose. Two of the patients died: one with disseminated intravascular coagulation and circulatory collapse, one with severe rhabdomyolysis and ischemic colitis. Among the other three cases, one developed acute psychosis, hyperthermia and rhabdomyolysis, one developed acute respiratory distress syndrome and one pericarditis. The effects of amphetamine are discussed along with the diagnosis and treatment of patients with such poisoning.

A 32-year-old woman was admitted with a diagnosis of impending premature delivery. In the 37th week of pregnancy, vaginal examination was performed. After ten minutes, vomiting, whole body flushing, and cold sweat appeared suddenly. Because fetal heart rate became 60-70 beats.min-1, emergency caesarean section was scheduled. When she arrived at the operating room, blood pressure was 75/45 and heart rate was 122 beats.min-1. Five minutes later, anesthesia was induced with thiopental and vecuronium, and operation was instituted concomitantly. After the delivery, pentazocine and midazolam were administered. During the operation, premature separation of normally implanted placenta or pressed cord was not observed. Hydrocortisone was administered for circulatory collapse. Gabexate mesilate was administered for the prevention of DIC. The scratch test, performed ten days later, revealed that latex was positive but lidocaine was negative. Therefore, it was concluded that anaphylaxis induced by latex gloves caused shock after internal examination.

We report the case of a 43-year-old schizophrenic who sustained, after 12 days of treatment including olanzapine (20 mg.day-1), carbamazepine, levomepromazine and alprazolan, a severe shock with bradycardia (HR: 40 b.min-1), circulatory collapse (SAP: 60 mmHg), hypothermia (T: 27 degrees C), coma and disseminated intravascular coagulation. A significant improvement was obtained with high doses of intravenous glucagon, whereas the normalization of central temperature, atropine, adrenaline and volume loading had been inefficient. Olanzapine, alone of associated with other psychotropics, could cause severe circulatory collapse with hypothermia and coma responding to a treatment including glucagon.

Endotoxic lipopolysaccharide (LPS) is a proinflammatory agonist produced by gram-negative bacteria and a contributor to the majority of the 400,000 septic shock cases recorded annually in US hospitals. The primary target cells for LPS are monocytes and macrophages. Their response consists of massive production of proinflammatory cytokines, reactive oxygen- and nitrogen-intermediates, procoagulants, and cell adhesion molecules. In turn, expression of these LPS-responsive factors contributes to collapse of the circulatory system, to disseminated intravascular coagulation, and to a 30% mortality rate. A common intracellular mechanism responsible for the expression of septic shock genes in monocytes and macrophages involves the activation of NF-kappaB. This transcription factor is regulated by a family of structurally related inhibitors including IkappaBalpha, IkappaBbeta, and IkappaBepsilon, which trap NF-kappaB in the cytoplasm. In this report, the investigators show that LPS derived from different gram-negative bacteria activates cytokine-responsive IkappaB kinases containing catalytic subunits termed IKKalpha (IKK1) and IKKbeta (IKK2). The kinetics of IKKalpha and IKKbeta activation in LPS-stimulated human monocytic cells differ from that recorded on their stimulation with tumor necrosis factor-alpha, thereby implying a distinct activation mechanism. LPS-activated IKK complexes phosphorylate all 3 inhibitors of NF-kappaB: IkappaBalpha, IkappaBbeta, and IkappaBepsilon. Moreover, LPS activates IKKbeta preferentially, relative to IKKalpha. Thus, IKK complex constitutes the main intracellular target for LPS-induced NF-kappaB signaling to the nucleus in human monocytic cells to activate genes responsible for septic shock.

Dengue virus infection can cause a wide spectrum of illness. Thrombocytopenia with concurrent haemoconcentration differentiates dengue haemorrhagic fever from classical dengue fever. Only cases with shock or unstable vitals signs need admission in the pediatric intensive care. The management is essentially supportive and symptomatic. The key to success is frequent monitoring and changing strategies. A rise in hematocrit of 20% along with a continuing drop in platelet count is an important indicator for the onset of shock. Patients in grade I and II should be closely monitored for signs of shock. The management of dengue shock syndrome (grade III and IV) is a medical emergency needing prompt and adequate fluid replacement for the rapid and massive plasma losses through increased capillary permeability. Early and effective replacement of plasma losses with plasma expanders or fluid and electrolyte solutions results in a favourable outcome in most cases. The ideal fluid management should include both cystalloids and colloids (including albumin). Cystalloids are given as boluses as rapidly as possible, and as many as 2 to 3 boluses may be needed in profound shock. Colloidal fluids are indicated in patients with massive plasma leakage and in whom a large volume of cystalloids has been given. Frequent recording of vital signs and determinations of haematocrit are important in evaluating the results of treatment. Apart from correction of electrolyte and metabolic disturbances, oxygen is mandatory in all patients of shock. Some patients develop DIC and need supportive therapy with blood products (blood, FFP and platelet transfusions). Polyserositis, in the form of pleural effusion and ascitis, are common in cases of dengue shock syndrome, and if possible, drainage should be avoided as it can lead to severe hemorrhages and sudden circulatory collapse. The prognosis depends mainly on the early recognition and treatment of shock.
