A 57-year-old man was admitted with dyspnea and bloody sputum. The chest X-ray showed unilateral alveolar infiltration, and alveolar cell carcinoma was suspected. Physical examination showed orthopnea and a loud systolic murmur, and the echocardiogram showed mitral valve prolapse. A chest X-ray 4 days later revealed bilateral infiltration. The cardiac catheterization showed pulmonary congestion and the capillary wedge pressure revealed a prominent V wave. Papanicolaou's test of sputum was negative. These findings suggested heart failure due to mitral regurgitation rather than lung carcinoma. The patient underwent mitral valve replacement because of his refractoriness to the medical treatment. During the operation, the chordae tendineae of the anterior mitral leaflet was found to be completely ruptured. The mechanisms of unilateral pulmonary edema could not be ascertained, but the effect of posture and gravity was thought to be a possible mechanism.

The safety and efficacy of intravenous (i.v.) torsemide as adjunctive therapy for acute cardiogenic pulmonary edema was evaluated. Thirteen patients were treated with i.v. torsemide and six patients, with i.v. furosemide, as a positive control. Doses of torsemide, 20 mg or 40 mg, and furosemide, 40 mg or 80 mg, were administered initially. The dose was titrated as necessary over the next 24 hours. In patients who received i.v. torsemide, median fractional sodium excretion significantly increased from 2.88% (0.04-10.1%) at baseline to 6.76% (0.71-11.6%) at peak (P = 0.0342). Hourly urine volume increased from 134 mL (25-400 mL) to 375 mL (145-790 mL) (P = 0.0034). Torsemide administration resulted in a significant improvement in both pulmonary rales and orthopnea. None of the patients experienced serious adverse events or required withdrawal from the study. These results suggest that i.v. torsemide is an effective and well-tolerated diuretic in patients with acute cardiogenic pulmonary edema.

Pulmonary edema is a frequent and common cause of death in patients in critical care settings. It is seen as a complication of myocardial infarcts, hypertension, pneumonia, smoke inhalation, and high-altitude pulmonary edema. Pulmonary edema occurs when there are alterations in Starling forces and capillary permeability, opposition to lymphatic flow in the lungs, decreased plasma oncotic pressure, central nervous system lesions, and following some types of strenuous exercise. Pulmonary edema presents initially with crackles, wheezing, and dry cough and progresses to tachypnea, dyspnea, orthopnea, pink frothy sputum, and cyanosis. Treatment involves supportive therapy, reduction in blood volume, and oxygen therapy.

Medical records of 150 patients with high-altitude pulmonary edema seen over a 39-month period in a Colorado Rocky Mountain ski area at 2,928 m (9,600 ft) (mean age 34.4 years; 84% male) were reviewed. The mean time to the onset of symptoms was 3 +/- 1.3 days after arrival. Common symptoms were dyspnea, cough, headache, chest congestion, nausea, fever, and weakness. Orthopnea, hemoptysis, and vomiting were rare, occurring in 7%, 6%, and 16%, respectively. Symptoms of cerebral edema occurred in 14%. A temperature exceeding 100 degrees F occurred in 20%, and 17% had a systolic blood pressure of 150 mm of mercury or higher. Blood pressures were higher in patients older than 50 years (142 mm of mercury). Rales were present in 85%, and a pulmonary infiltrate was present in 88%; both were most commonly bilateral or on the right side. The amount of infiltrate was mild. Men appeared to be more susceptible than women to high-altitude pulmonary edema. Pulse oximetry in 45 patients showed a mean oxygen saturation of 74% (38% to 93%). Treatment methods depended on severity and included a return to quarters for portable nasal oxygen, an overnight stay in the clinic for continuing oxygen, or a descent to Denver for recovery or admission to a hospital. All patients received oxygen for 2 to 4 hours in the clinic. There were no deaths or complications.

A syndrome of acute pulmonary edema has been previously reported among scuba divers in cold, European waters. Because of the temperatures involved, the name "cold-induced pulmonary edema" was coined in the original 1989 description. We report six individuals who developed the identical syndrome, five while diving in Puget Sound and one in the Gulf of Mexico. The four women and two men ranged in age from 24 to 60 yr. They experienced one to six episodes apiece, each with the development severe dyspnea at depth without excessive exertion. Associated symptoms included cough, weakness, expectoration of froth, chest discomfort, orthopnea, wheezing, hemoptysis, and dizziness. Emergency medical evaluation of four divers revealed rales on examination and pulmonary edema on chest radiograph. In one diver with pulmonary edema on chest radiograph, pulmonary capillary wedge pressure was normal when measured acutely. Symptoms resolved either spontaneously over 1-2 days or with standard medial treatment for pulmonary edema. Prior history of cardiovascular disease was negative except for hypertension and mitral valve prolapse in one diver. Cardiac evaluations following recovery from the acute episodes were normal. Episodes in the cold waters of Puget Sound sometimes occurred despite the use of dry suits. Furthermore, one diver developed recurrent episodes in 27 degrees C water off Cozumel, Mexico. Development of pulmonary edema while scuba diving constitutes a distinct clinical entity which may occur in either "cold" or "warm" water. It is not associated with a decompression mechanism. Personnel caring for divers should be aware of the syndrome in order to provide optimal medical management.

The long term impact of pre-hospital thrombolysis in acute myocardial infarction on the subsequent development of heart failure symptoms was investigated in 362 consecutive patients. The pre hospital strategy, used in 61 patients, allowed for very early administration of streptokinase, within 1.2+/-0.6 (mean+/-S.D.) hours from pain onset. In contrast, 294 patients treated in hospital received lytic treatment within 2.0+/-0.9 hours. The pre hospital group showed faster reperfusion, as measured by the time to peak creatine kinase and to ST segment recovery, but only a slightly better ventricular function, as compared to hospital treated patients. Heart failure symptoms were significantly reduced in the pre hospital group during hospitalization and at long term follow up: there were less dyspnea, fatigue, orthopnea, nocturnal dyspnea, nocturia, peripheral edema and episodes of pulmonary edema. Angina was reduced as well. We conclude that the initial benefit of prehospital thrombolysis translates into long term reduction of heart failure symptoms, thus improving quality of life.

Epidemic dropsy results from the consumption of edible oils adulterated with Argemone mexicana oil by unscrupulous traders. Twenty consecutive 'in-door' patients of dropsy were intensively studied during the recent Delhi epidemic. Samples of edible oil used by them, their urine and their serum samples tested positive for sanguinarine on thin layer chromatography. The illness starts as a gastro-enteric illness followed by oliguria and pedal oedema. The following are often observed: cutaneous erythema with blanching and tenderness on pressure; violacious pigmentation of the skin; shortness of breath with orthopnoea; right-sided heart failure with normal left ventricle (LV) functions; as well as severe anaemia and hypoalbuminaemia. Renal function tests showed: bland urinary sediments; decreased glomerular filtration rate (GFR); mild to moderate azotaemia; acute tubular necrosis; patchy pneumonitis; moderate hypoxia with respiratory alkalosis; and restrictive ventilatory defects on blood gas analysis; and spirometry suggestive of interstitial pulmonary oedema of non-cardiogenic origin. 99mTc colloid sulphur liver scans showed colloid shift. There was marked dilatation and proliferation of dermal capillaries in the absence of significant inflammation in the biopsy specimens. Toxic alkaloids of Argemone mexicana oil induce widespread capillary dilatation and permeability causing leakage of protein rich plasma into the interstitial tissues of various organs. A hypovolaemic state is thus induced producing renal hypoperfusion which may progress to acute tubular necrosis. Interstitial fluid in alveoli causes restrictive ventilatory dysfunction with hypertension and right-sided failure with well-preserved LV function. The hepatic venous congestion induces Kupffer's cell dysfunction, which results in colloid shift on a radionuclide liver scan.

Quinine sulfate, which has been available for many years, has not been implicated definitively in the development of pulmonary toxicity. A variety of adverse effects, however, have been reported with quinine administration. A 45-year-old woman with longstanding rheumatoid arthritis experienced wheezing, severe anxiety, breathlessness, cough, orthopnea, mild fever, chills, and pleuritic chest discomfort after taking a single dose of quinine for nocturnal leg cramps. Radiographic imaging demonstrated diffuse, bilateral pulmonary infiltrates suggestive of pulmonary edema. No cause other than acute quinine ingestion could be identified despite thorough cardiac and infectious disease evaluations. Clinicians should be aware of a possible association between quinine sulfate and pulmonary toxicity.

A 33 years old woman was admitted to the hospital after four days with cough, dyspnea, orthopnea and hemoptysis. Blood pressure was 170/90 mmHg, pulse was 112 and temperature was normal. She had cyanosis and a left ventricular gallop, without heart murmurs. A chest radiograph revealed pulmonary edema and echocardiogram showed a global left ventricular systolic disfunction. Oxygen and furosemide were started, but cardiopulmonary collapse ensued. The patient was supported with mechanical ventilation and treated with inotropic drugs. A right sided cardiac catheterization showed pulmonary wedge pressure of 18 mmHg and a cardiac index of 3 l/min/m2. The levels of creatinine and urea nitrogen were elevated and a urine protein was 97 mg/dl. Coagulation tests were normal except by a positive lupic anticoagulant. Markers of connective tissue diseases or vasculitis were negatives. The clinical evolution suggested that a catastrophic antiphospholipid syndrome was ongoing. Intravenous corticoids, gammaglobulin and cyclophosphamide were administered with transient improvement. On her fourth day of treatment, the patient presented sudden pulmonary bleeding and embolism. A plasmapheresis was performed with improvement of renal, cardiac and pulmonary function. After this episode, the patient has been treated with prednisone and oral anticoagulants treatment for the last two years, without further clinical events.

Almost one mountain trekker or climber out of two develops several symptoms of high altitude illness after a rapid ascent (> 300 m/day) to an altitude above 4000 m. Individual susceptibility is the most important determinant for the occurrence of high altitude pulmonary oedema (HAPE). Symptoms associated with HAPE are incapacitating fatigue, chest tightness, dyspnoea at the slightest effort, orthopnoea, and cough with due to haemoptysis in an advanced stage of the disease pink frothy sputum. The hallmark of HAPE is an excessively elevated pulmonary artery pressure (mean pressures of 35 and 55 mm Hg), which precedes the development of pulmonary oedema. Elevated pulmonary capillary pressure and protein- as well as red blood cell-rich oedema fluid without signs of inflammation in its early stage are characteristic findings. Furthermore, decreased fluid clearance from the alveoli may contribute to this non-cardiogenic pulmonary oedema. Immediate descent or supplemental oxygen and nifedipine are recommended until descent is possible. Susceptible individuals can prevent HAPE by slow ascent: an average gain of altitude not exceeding 400 m/day above an altitude of 2500 m. If progressive high altitude acclimatization is not possible, a prophylaxis with nifedipine should be recommended.
