Aluminum phosphide (ALP) is highly toxic to the lungs, heart and blood vessels causing pulmonary edema, shock and arrhythmias. There is massive focal myocardial damage resulting in raised cardiac enzymes. This study included 92 patients of proven ALP poisoning. The age varied between 20-50 years and the majority (74) were females. Clinical manifestations were nausea and vomiting (92), dyspnea and palpitation (72 each), cyanosis (54), hypotension (32) and shock (46) etc. Cardiac arrhythmias were present in 80 cases and hypermagnesemia in 78 patients. Mean serum magnesium level (1.95 +/- 0.18 mE/l) was significantly (p less than 0.01) raised compared to mean magnesium level in control subjects (1.62 +/- 0.26 mEq/l). Hypermagnesemia results from myocardial and liver damage and to our knowledge has not been described in the literature. Of 92 cases studied, 66 died, 60 of whom died within 24 hours of ALP ingestion. Treatment is supportive.

Aluminium phosphide (ALP) a major suicidal agent in the developing countries is freely available as grain fumigant. It is highly toxic to lungs, heart and blood vessels causing pulmonary oedema, shock and arrhythmias. There is massive focal myocardial damage resulting in raised cardiac enzymes. Clinical manifestations were nausea and vomiting (32), dyspnoea and palpitations (25 each), cyanosis (12), hypotension (12) and shock (15). Cardiac arrhythmias were present in 28 cases and hypermagnesaemia in 13 patients. Mean serum magnesium level (1.95 +/- 0.2O, mEq/L) was significantly raised compared to mean magnesium level in control subjects (1.62 +/- 0.23 mEq/L). Hypermagnesaemia occurs due to myocardial and liver damage. Out of 32 cases studied, 22 died 18 within 24 hours of ALP ingestion. Thirty two cases of ALP were studied.

Androgen deprivation displays the mean therapy of advanced stage prostatic cancer, independently of palliative radiotherapy. The evolution to hormone-resistance status leads to a fatal tumor progression. High-dose fosfestrol (diethylstilbestrol diphosphate) has been suggested to circumvent hormone-resistance and to induce a direct cytotoxic effect. Sixteen patients with hormone-resistant prostate cancer were treated by continuous infusion of high-dose fosfestrol according to two schedules: 10 patients were included in a phase I trial of a daily escalating dose from 1.5 g/d to 4.5 g/d for 7 to 10 days. Six other patients were uniformly treated by 4 g/d for 3.5 h for 5 days. Between each course, patients received orally 300 mg/d fosfestrol and 200 mg/d salicylic acid. The mean age was 65 years (range 51-75). Mean number of courses was two (extremes 1-7). Toxicities: reversible weight gain was observed in five patients. One patient presented a pulmonary edema which was resolved immediately after diuretics. One patient and 9 patients respectively experienced grade III and II (OMS) nausea and vomiting. Transient perineal pruritus occurred in 5 patients. Responses: 15 patients were evaluable (one early death occurred on day 3 from tumor progression complicated by an intravascular coagulation disease). There were four objective stabilizations (NPCP criteria) lasting 2 m, 2 m, 5 m and 10 m respectively. Subjective improvement of pain was observed in five other patients. There was more than 50% reduction of PSA in eight patients. High-dose fosfestrol seems to have some objective activity with moderate toxicity and warrants further investigation.

The alkylator-like agent ifosfamide, which has been found to be useful in the treatment of a number of solid tumors, can have severe central nervous system (CNS) side effects in addition to causing myelosuppression, nephrotoxicity, nausea and vomiting, pulmonary edema, and interstitial pneumonitis. This article, including a case study and a protocol, prepares nurses to do patient education and to observe, assess, and provide care for patients who may experience the CNS toxicity that ranges from mild changes to severe disturbances of mental state.

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.

The absence of osmotic diuresis modifies the effects of hyperglycemia on body fluids in patients with advanced renal failure. To determine the relationship between clinical manifestations and abnormalities in tonicity and extracellular volume in such patients, we analyzed 43 episodes of severe dialysis-associated hyperglycemia (serum glucose exceeding 600 mg/dL) treated only with insulin. The main manifestations were dyspnea in 22 cases (pulmonary edema in 19), nausea and vomiting in 15, coma in 13 and seizures in 3, while 5 patients had no symptoms. Treatment with insulin resulted in a decrease in serum glucose value from 913 +/- 197 mg/dL to 170 +/- 78 mg/dL, an increase in serum sodium level from 125 +/- 5 to 136 +/- 5 mmol/L, and a fall in calculated serum tonicity value from 300 +/- 13 to 282 +/- 11 mmol/kg (all at p < 0.001). The ratio of the change in serum sodium level over change in serum glucose concentration was -1.50 +/- 0.22 mmol/L per 100 mg/dL. The percent increase in extracellular volume secondary to hyperglycemia developing from the prior euglycemic state and calculated from changes in serum sodium and chloride concentrations, was 10.9% +/- 4.6% (1.5% +/- 0.6% per 100 mg/dL increase in serum glucose level). All clinical manifestations dissipated after correction of hyperglycemia in 42 patients. One woman developed during treatment a fatal myocardial infarction. Dialysis patients with severe hyperglycemia may develop symptoms as a result of hypertonicity and extracellular expansion. Insulin alone may be sufficient treatment for these symptoms. The changes in serum tonicity and electrolytes during treatment are consistent with theoretical predictions.

Acute carbon monoxide poisoning is the most common cause of poison-related deaths in the U.S. A 21-year-old white woman was referred to Ruby Memorial Hospital after exposure to carbon monoxide (CO) from a faulty furnace. She developed acute weakness, dyspnea, nausea and vomiting. An electrocardiogram revealed sinus tachycardia, non-specific ST-T wave abnormalities, and a prolonged QTc interval. The chest X-ray revealed pulmonary edema and the 2-D echocardiography revealed decreased left ventricular systolic function with an ejection fraction of 25%. She was treated with high-flow oxygen and supportive medical therapy with complete resolution of the left ventricular dysfunction six weeks later. She has been followed for over one year without medical therapy and without recurrence of her symptoms. This case illustrates that the depressant effect of CO poisoning on the myocardium can be reversed in the short term with supportive medical therapy and recovery sustained in the long term without medical therapy.

Selenium is a ubiquitous element in the environment essential to the human diet and widely utilized in industrial processes. Fatal human selenium intoxication is rare. The authors report a case in which investigators recovered a bottle of gun-bluing agent beside a 24-year-old man. He exhibited signs and symptoms typical of acute selenium intoxication presenting with nausea and vomiting, followed by pulmonary edema and rapid cardiovascular collapse approximately 3 to 4 h after ingestion. Classic electrocardiographic (EKG) changes, which have been reported to occur in acute selenium intoxication, included sinus tachycardia with ST wave alteration. Toxicological results confirmed elevated blood and tissue concentrations. The cause of death was ascribed to acute selenium intoxication, which ensued rapidly after oral consumption. The manner of death was suicide. This case report, which presents an overview of acute and chronic selenium poisoning, underscores the value of thorough toxicologic analyses of tissue and body fluids in humans.

Severe uremia is now a rare occurrence in most developed nations, and yet is still present in many countries of the world. It includes clinical manifestations such as calciphylaxis and uremic frost, which are now rarely seen. Patients with extremely high levels of blood urea nitrogen (above 175 mg/dL) are at a higher risk of experiencing first-time hemodialysis-related complications, in particular dialysis disequilibrium syndrome (DDS). DDS is a central nervous disorder characterized by a wide variety of neurological symptoms that range from nausea and vomiting to even death due to cerebral edema. There are 2 main theories to explain its pathophysiology: the reverse urea effect, which considers that the shift of urea between brain intracellular space and plasma is not immediate, causing a higher concentration of urea within the brain and leading to cerebral edema. The second theory considers that after hemodialysis, patients have transient paradoxical metabolic acidosis within the central nervous system, displacing Na(+) and K(+) from organic anions, making them osmotically active and again leading to cerebral edema. The main goal is to prevent the occurrence of DDS, for which there are several proposed measures including continuous renal replacement therapies. Once established, treatment should be focused on supportive therapy. Another uncommon phenomenon described in patients who initiate hemodialysis is transient pulmonary leukocyte margination, which in conjunction with an inflammatory milieu, may lead to non-cardiogenic pulmonary edema. We present the case of a young adult with severe uremia who, despite application of recommended measures, developed DDS and non-cardiogenic pulmonary edema.
