In a two year period 44 endobronchial resections using the Neodymium-YAG laser have been performed in 28 patients. The majority of cases had either bronchogenic carcinoma (57%) or metastatic carcinoma (18%) involving the bronchial tree. Adenoid cystic carcinoma, benign tumours, lymphoma, tracheal papillomatosis, Wegener's granulomatosis and benign stricture comprised the other cases. Rigid bronchoscopy and general anaesthesia were used in the majority. Symptomatic improvement of dyspnoea when relief of bronchial obstruction occurred was marked in ten of 17 cases, moderate in four and absent in three. Haemoptysis was markedly improved in two of three cases and obstructive pneumonitis resolved in one of two cases. Significant respiratory function improvement was observed in Raw (most sensitive), FEV11, FVC and TLC. Laser treatment restored the lumen to normal calibre in 52% (including all patients with tracheal lesions), to greater than half normal in 28% and to less than half normal in 20% of cases. Re-expansion of a collapsed lung or lobe occurred in seven of eight patients. In six of these patients laser treatment was the initial therapy resulting in immediate re-expansion and symptomatic relief prior to further therapy. In patients with bronchogenic carcinoma the mean time to retreatment or death was 72 days. For metastatic carcinoma this was 60 days. Two early deaths (3 hours, 36 hours) due to respiratory failure occurred in patients with very severe bilateral bronchial obstruction too advanced for effective clearance. Other complications included laryngeal oedema requiring prolonged intubation (1), bronchospasm (1), atrial fibrillation (1), and acute pulmonary oedema (1). Laser treatment provides effective palliation for bronchial obstruction and haemoptysis in selected proximal endobronchial cancers.

Neurogenic, or postictal, pulmonary edema is a rare complication of grand mal seizures. At present, the etiology of this disorder is complex and not understood fully. This report describes a case of a young man who was previously healthy, but who subsequently developed acute pulmonary edema after a grand mal seizure. The patient presented with gross hemoptysis, which has not been described previously in this disorder. The pathogenesis, diagnosis, and treatment of neurogenic pulmonary edema are discussed.

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.

Acute pulmonary edema may be induced by diving and strenuous swimming. We report the case of a diver using closed-circuit, scuba equipment who developed acute dyspnea, hemoptysis, and hypoxemia following a dive in 18 degreesC (64.4 degrees F) water and physical exertion during the swim back to shore. With the growing popularity of recreational scuba diving, emergency physicians are liable to be faced with increasing numbers of diving-related medical problems. Diving-induced pulmonary edema should be included in the differential diagnosis of acute hypoxemia, sometimes accompanied by acid-base abnormalities, when this is seen in a diver.

Acute pulmonary oedema has been described in individuals participating in three aquatic activities: (i) scuba diving; (ii) breath-hold diving; and (iii) endurance swimming. In this review, 60 published cases have been compiled for comparison. Variables considered included: age; past medical history; activity; water depth, type (salt or fresh) and temperature; clinical presentation; investigations; management; and outcome. From these data, we conclude that a similar phenomenon is occurring among scuba, breath-hold divers and swimmers. The pathophysiology is likely a pulmonary overperfusion mechanism. High pulmonary capillary pressures lead to extravasation of fluid into the interstitium. This overperfusion is caused by the increase in ambient pressure, peripheral vasoconstriction from ambient cold, and increased pulmonary blood flow resulting from exercise. Affected individuals are typically healthy males and females. Older individuals may be at higher risk. The most common symptoms are cough and dyspnoea, with haemoptysis also a frequent occurrence. Chest pain has never been reported. Radiography is the investigation of choice, demonstrating typical findings for pulmonary oedema. Management is supportive, with oxygen the mainstay of treatment. Cases usually resolve within 24 hours. In some cases, diuretics have been used, but there are no data as to their efficacy. Nifedipine has been used to prevent recurrence, but there is only anecdotal evidence to support its use.

A 67-year-old woman abruptly developed acute pulmonary oedema, severe bradycardia and then cardiac arrest while in hospital 6 days after an elective hernia repair. She was resuscitated, intubated and transferred to the intensive care unit. Within 24 hours, she began to display repetitive, generalised myoclonic jerks that failed to respond to therapy with conventional anticonvulsants; an electroencephalogram confirmed myoclonic status. After administration of levetiracetam was begun on Day 3, myoclonic jerks reduced, and there was gradual clinical improvement. By Day 6 after the arrest, the patient was alert and oriented (Glasgow Coma Score, 15/15). Although she died on Day 11 after massive haemoptysis and cardiac arrest, this patient demonstrates the possibility of reasonable neurological recovery despite early onset of myoclonic status.

Acute pulmonary edema complicating electroconvulsive therapy is an extremely uncommon event that has rarely been described in the literature. Different theories, including one suggesting a cardiogenic component, have been proposed to explain its genesis. The present report describes a classic presentation of this condition with review of its potential mechanisms and diagnostic approach. After successful completion of a session of electroconvulsive therapy, a 42-year-old woman with major depressive disorder developed acute systemic high blood pressure, shortness of breath, and hemoptysis. A chest radiograph demonstrated diffuse bilateral pulmonary infiltrates. Initially cardiogenic pulmonary edema was presumed, but an extensive diagnostic work-up demonstrated normal systolic and diastolic left ventricular function, and with only supportive measures, a complete clinical and radiographic recovery was achieved within 48 hours. The present case does not support any cardiogenic mechanism in the genesis of this condition.

A 43-year-old full-term pregnant woman (gravida 2, para 1, medical history of gestational diabetes mellitus) developed a sudden and malignant hypertension with hemoptysis, sweat, and tachycardia during a scheduled C-section. A dead newborn was delivered and was successfully resuscitated. The mother died after resistant cardiac arrest. Autopsy and pathological analyses revealed an acute pulmonary edema and a necrotic and hemorrhagic voluminous tumor of the left adrenal gland, which was a pheochromocytoma. Pheochromocytoma is a rare tumor of the adrenal glands which secretes catecholamines. In pregnant women, its symptoms can mimic gestational hypertension, preeclampsia or eclampsia, and gestational diabetes mellitus. The gestational diabetes mellitus was presumed to be a symptom of the pheochromocytoma, and cardiopulmonary failure the result from the necrosis of the tumor provoked by gravid uterus compression. From a medico-legal point of view, the tumor could not have been suspected during the pregnancy.

Cocaine can be responsible for many psychiatric and/or somatic disorders. The aim of this systematic literature review of data was to expose relations between cocaine use and pulmonary complications. Cocaine can be responsible for acute respiratory symptoms (cough, black sputum, hemoptysis, dyspnea, wheezing, chest pain) and for various pulmonary disorders including barotrauma (pneumothorax, pneumomediastinum, subcutaneous emphysema, pneumopericardium), airway damage, asthma, bronchiolitis obliterans with organizing pneumonia, acute pulmonary edema, alveolar hemorrhage, alveolar pneumonia with carbonaceous material, bullous emphysema, acute eosinophilic pneumonia, pulmonary granulomatosis caused by talc or cellulose, interstitial pneumonitis and pulmonary fibrosis, vasculitis, pulmonary hypertension, pulmonary embolism and pulmonary infarction, mycotic pulmonary arterial aneurysms, septic emboli, aspiration pneumonia, community-acquired pneumonia, HIV-related opportunistic infections, latent tuberculosis infection, pulmonary tuberculosis, lung cancer and crack lung. Some of these complications are serious and may have a fatal outcome. Pulmonary function tests, thoracic tomodensitometry, bronchial fibroscopy with bronchoalveolar lavage and lung scintigraphy may be an aid to the diagnosis of these pulmonary compications. Cocaine use must be sought in case of respiratory symptoms in young persons.
