Naloxone is a non-selective, short-acting opioid receptor antagonist that has a long clinical history of successful use and is presently considered a safe drug over a wide dose range (up to 10 mg). In opioid-dependent patients, naloxone is used in the treatment of opioid-overdose-induced respiratory depression, in (ultra)rapid detoxification and in combination with buprenorphine for maintenance therapy (to prevent intravenous abuse). Risks related to naloxone use in opioid-dependent patients are: i) the induction of an acute withdrawal syndrome (the occurrence of vomiting and aspiration is potentially life threatening); ii) the effect of naloxone may wear off prematurely when used for treatment of opioid-induced respiratory depression; and iii) in patients treated for severe pain with an opioid, high-dose naloxone and/or rapidly infused naloxone may cause catecholamine release and consequently pulmonary edema and cardiac arrhythmias. These risks warrant the cautious use of naloxone and adequate monitoring of the cardiorespiratory status of the patient after naloxone administration where indicated.

In order to reduce intradialytic and interdialytic morbidity, it is important to obtain a zero sodium balance at the end of each dialysis session. This can be achieved by matching exactly the interdialytic sodium and water intake with the intradialytic sodium and water removal. A positive sodium balance can be obtained by using hypernatric dialysis or "sodium ramping" or convective techniques. While reducing the intradialytic side effects (hypotension, cramps, nausea, vomiting), these methods may increase the interdialytic side effects (thirst, weight gain, hypertension and pulmonary edema). Given the highly variable amounts of sodium introduced during the interdialytic periods, the use of sodium-conductivity kinetic models allows removing exactly the amount of sodium accumulated in the interdialytic period. This strategy may be advantageous towards cardiovascular stability in patients prone to dialysis hypotension.

A previously healthy 9-year-old Japanese boy with a 4-day history of vomiting and headache died suddenly and unexpectedly. An external examination revealed no abnormalities other than foam around the mouth and nose. An internal examination revealed severe pulmonary edema and hemorrhagic hemangiopericytoma arising from the choroid plexus of the right lateral ventricle. The cause of death was thought to be neurogenic pulmonary edema caused by the rapid growth of a hemangiopericytoma, with intratumoral hemorrhage.

Defined by the association of hemolysis, hepatic dysfunction and thrombocytopenia, the Hemolysis, Elevated Liver enzyme, Low Platelets (HELLP) syndrome can complicate preeclampsia and worsen maternal and fetal prognosis. It can be diagnosed in the immediate postpartum (30%) or in the absence of preeclampsia (10-20%). Clinical diagnosis can be difficult because there is no specific symptom. Abdominal pain or vomiting during the third trimester must lead to think about this diagnosis. Biological criteria are well defined: hemolysis by the presence of schistocytes, increased serum total bilirubin >12 mg/L or LDH >600 IU/L, hepatic dysfunction by increased transaminases and thrombocytopenia by a platelet count <100,000/microL. The evolution of those parameters is a major prognostic factor. With the HELLP syndrome, maternal morbidity is dramatically increased compared to isolated preeclampsia with complications such as eclampsia, placental abruptio, disseminated intravascular coagulation, pulmonary edema, acute renal insufficiency, subcapsular liver hematoma. The management of a HELLP syndrome requests level 3 hospital with intensive care units for neonate and mother. The treatment of this syndrome requires termination of the pregnancy as soon a possible, either by cesarean section or by vaginal delivery if cervical conditions are optimal (without any maternal or fetal complications). Before 32 weeks, a more expectative attitude could be acceptable with the prematurity permitting corticotherapy for fetal pulmonary maturation. This corticotherapy can improve temporary biological parameters but there are no proven benefits to consider improvement for long term maternal or fetal prognosis. During the postpartum, evolution is usually spontaneously favorable. Recurrences are not frequent.

High-dose interleukin-2 (IL-2), given via continuous intravenous (i.v.) infusion, induces lymphokine-activated killer (LAK) cell cytotoxicity against tumor cells. These LAKs exhibit enhanced cytotoxicity against tumor cells in vitro when they are subsequently pulsed with additional IL-2. Famotidine may increase LAK cytotoxicity against neoplastic cells by allowing for greater IL-2 uptake at the IL-2 receptor on lymphocytes. Twenty-three (23) patients received famotidine 20 mg i.v. twice per day and continuous-infusion IL-2 (18 MIU/m(2)/24 hours) for 72 hours, followed by a 24-hour rest, then 1-3 daily-pulse IL-2 doses of 18 MIU/m(2) over 15-30 minutes preceded by famotidine 20 mg i.v. Cycles were repeated every 3 weeks. The most common metastatic sites were lung, lymph node, and subcutaneous/soft tissue. The most common toxicities were fever, rigor, nausea/emesis, hypophosphatemia, hypotension, elevated creatinine, and pulmonary edema. There were no treatment-related deaths. One (1) complete (4%) and 9 partial responses (39%) were seen (43% total response rate; 95% confidence interval: 22%-65%). Median survival for all patients is 13 months. The combination of famotidine and high-dose continuous infusion + pulse IL-2 is active in metastatic melanoma.

A rare case of cardiac failure due to hypertensive crisis in pheochromocytoma in a 25-year-old young man is presented. In the Emergency Department the patient complained of persisting headache and vomiting; he was distressed but fully alert, his heart rate was 110 b/min and blood pressure 180/80 mmHg. Few hours after admission, the clinical course suddenly got worse with signs and symptoms of fatal cardiac shock (dyspnoea, cyanosis, pulmonary oedema, hypocontractility of left ventricle). Autopsy revealed a large tumour of the left adrenal gland. Histological examination confirmed macroscopic suspicion of pheochromocytoma. Catecholamine serum levels were analysed by high pressure liquid chromatography (HPLC) with electrochemical detection. The urine contained 35 microg/24 h norepinephrine and 184 microg/24 h epinephrine (normal range < or = 64 and < or = 36 microg/24 h respectively). These laboratory findings impressively demonstrate that the tumour was active, secreting high levels of epinephrine. Cardiac failure due to an acute catecholamine-related hypertensive crisis was established as the cause of death.

High altitude sickness is a common name for illnesses that can occur at high altitude, usually above 3000 meters from sea level. The cause is hypoxia but the pathophysiology of the diseases is a complex mixture of multiple factors, involving the human response to hypoxia. The most common symptom is headache, but loss of appetite, nausea and sleep disturbances are also common complaints. With rapid or high ascent there is increased risk of acute mountain sickness, with severe headache that responds poorly to pain medications, nausea, vomiting and extreme fatigue as the most common symptoms. The most severe forms of high-altitude sickness are high altitude cerebral edema and high altitude pulmonary edema. High altitude sickness can be prevented by slow ascent and avoiding overexertion. Medications can also be used to reduce symptoms. In this overview high altitude physiology and acclimatisation are reviewed. The main types of high altitude sickness are described with special emphasis on symptoms and diagnosis, but treatment and prevention are also reviewed.

The cases of two 6 and 9-year-old sisters with lethal poisoning by inhalation of aluminium phosphide, after its inadequate use in a rural environment, are described. The clinical symptoms consisted of sudden vomiting, cardiac arrhythmias, shock, dyspnea, pulmonary edema/acute respiratory distress, metabolic acidosis and hepatic dysfunction, and the patients died in spite of advanced life support. Although an early diagnosis might theoretically improve the poisoning outcome, its high lethality rate and the absence of a specific antidote, efforts must be directed towards prevention and restricting its use as pesticide and being aware of its toxicity.

Ethiofencarb is one of the carbamate compounds, which are, in general, less toxic than organophosphorus insecticides. This is due to their reversible acetylcholinesterase inhibition and relative inability to cross the blood-brain barrier. Generally, ethiofencarb is regarded to be of low toxicity (LD(50) > 200 mg/kg); however, severe poisoning and death are not uncommon. To our knowledge, no measurements of ethiofencarb and its metabolites in human postmortem whole blood have been published. We present here a case report of fatal ethiofencarb intoxication with quantitative analysis of ethiofencarb and its metabolites in ante- and postmortem blood. In addition, postmortem urine was collected and analyzed. A 56-year-old man, who worked as a gardener, was found in poor condition, sitting in his car seat. He had been vomiting. The man was admitted to the local hospital about 1 h later. At admission, he was conscious, but unable to speak clearly. His condition deteriorated, and he developed severe pulmonary edema. Resuscitation with atropine and adrenaline were attempted, but he died approximately 3 h after admission. The analysis of postmortem peripheral blood revealed 0.12 g/100 mL ethanol, 26.4 mg/L ethiofencarb, 37.9 mg/L ethiofencarbsulfoxide, and 0.9 mg/L ethiofencarbsulfone. Ethanol (0.26 g/100 mL), ethiofencarb, ethiofencarbsulfoxide, and ethiofencarbsulfone were also detected in urine.

Glyphosate-surfactant (GlySH) is a commonly used herbicide that has been used in attempted suicide. Most reports of GlySH toxicity in patients have followed ingestion of the commercial product "Round-up" (Monsanto Ltd; Melbourne, Victoria, Australia), which consists of a mixture of glyphosate (as a isopropylanine salt) and a surfactant (polyoxyethyleneamine). Ingestion of Round-up is reported to cause significant toxicity including nausea, vomiting, oral and abdominal pain. Renal and hepatic impairment and pulmonary oedema may also occur. Impaired consciousness and encephalopathy have been reported as sequelae but there are limited data on the central nervous system (CNS) effects of Round-up toxicity. We report a 71-year-old male who attempted suicide with GlySH and developed a prolonged but reversible encephalopathy suggestive of acute CNS toxicity.
