A 47-year-old man was admitted to our hospital because of progressive dyspnea and cough. Physical examination and chest radiographs showed the signs of cor pulmonale. A lung scan using perfused radionuclide revealed multiple peripheral perfusion defects and catheterization of the right heart showed severe pulmonary hypertension. A diagnosis of severe pulmonary embolism was made. Despite intensive care with anti-coagulation therapy, the patient died on the third-hospital day. Autopsy disclosed gastric cancer in the pylorus with metastases to the regional lymph nodes. There were no macroscopic pulmonary artery emboli or parenchymal lesions, but more than 60% of the small arteries and arterioles were occluded by casts of tumor cells. Cor pulmonale due to a pulmonary tumor embolism is a rare complication of cancer. This case is particularly unusual because the embolus-caused cor pulmonale was the initial manifestation of clinically occult, but pathologically advanced, gastric cancer.

Iloprost is a stable prostacyclin analogue with a pharmacokinetic profile allowing nebulised administration in patients with primary pulmonary hypertension (PPH). Inhaled iloprost is a potent acute pulmonary vasodilator with a duration of action of about 60 minutes. It may exert additional long-term benefit through antiproliferative and antithrombotic effects. Inhaled iloprost 2.5 or 5 microg six or nine times daily for 12 weeks (n = 101) significantly (p < 0.01) improved a combined clinical endpoint of a > or =10% increase in distance walked in 6 minutes and an improvement of > or =1 class in New York Heart Association functional class without clinical deterioration or death (16.8 versus 4.9% of placebo recipients, n = 102) in patients with severe PPH or selected forms of nonprimary pulmonary hypertension. Statistical analysis of the response for the PPH subgroup (20.8 versus 5.5% with placebo; n = 51 and 51) was not reported. Improvements from baseline in exercise capacity and haemodynamic/gas exchange variables have been reported in patients with PPH with continued use of inhaled iloprost. In addition, improvement in preinhalation vascular resistance occurred after 12 weeks of inhaled iloprost (p < 0.01 versus placebo) in a large randomised trial. Increased cough, headache, flushing and an influenza-like syndrome were the most common adverse events in the largest trial of patients receiving inhaled iloprost. Headache, flushing and jaw pain occurred significantly more frequently with inhaled iloprost than with placebo.

A case of pulmonary thromboembolism with transient pulmonary hypertension of a rare cause is presented. In 24-year-old woman myasthenia was recognised on the ground of ptosis and fixation of eyes muscles from the 14th year of age. The treatment with mestinon was ineffective. Before planned thymectomy serious disturbances of heart rhythm and conduction were confirmed. Stimulator was implanted and thymectomy was done. No improvement of neurological state was observed despite the treatment with mestinone and prednisone. When she was 30 years old disease of lung appeared with fever, cough and parenchymal and pleural lesions of right lung. Antibiotic therapy was ineffective. CT scan and US examination revealed large thrombus inside the right auricle connected with stimulator electrodes. Embolisation of right pulmonary arteria was confirmed also. Treatment with heparin was ineffective and thrombectomy was performed. Exact neurological examination stated that the patient had no typical symptoms of myasthenia and that symptoms related with eyes and heart could be result of mitochondrial myopathy. Diagnosis was confirmed by EMG examination and muscle biopsy.

We describe a patient wih subacute cor pulmonale caused by tumor emboli in the lungs. A 64-year-old female suffering from a subacute progressive cough and shortness of breathing died of severe pulmonary hypertension seven days after admission. Neither chest CT scans nor lung perfusion scintigraphy showed any abnormal findings. Microscopic examination after an autopsy revealed diffuse intravascular tumor emboli occluding not only the small pulmonary arteries and arterioles, but also the lymphatic vessels, which were suggested to be metastases of a breast carcinoma resected five years previously. Thus, pulmonary tumor embolism should be considered in the differential diagnosis of primary pulmonary hypertension, particularly in patients with a past history of cancers.

Cough, sleep fragmentation and oxyhaemoglobin desaturation have all been documented during sleep in patients with cystic fibrosis (CF). It has been proposed that repeated episodes of nocturnal hypoxia act as a stimulus for the development of pulmonary hypertension and right ventricular failure, a complication that is associated with a poor prognosis. In addition, sleep disturbance from these events could lead to poor daytime function and quality of life. This review provides a detailed description of the mechanisms underlying sleep disordered breathing in this population, what is known regarding its effects upon daytime function and current treatment options. Most importantly, we review what is needed from future research in this challenging area of care in patients with CF.

Obstructive sleep apnea (OSA) occurs commonly in the U.S. population and is seen in both obese as well as non-obese individuals. OSA is a disease characterized by periodic upper airway collapse during sleep, which then results in either apnea, hypopnea, or both. The disorder leads to a variety of medical complications. Neuropsychiatric complications include daytime somnolence, cognitive dysfunction, and depression. Increased incidence of motor vehicle accidents has been documented in these patients and probably reflects disordered reflex mechanisms or excessive somnolence. More importantly, vascular disorders such as hypertension, stroke, congestive cardiac failure, arrhythmias, and atherosclerosis occur frequently in these patients. The lungs may be affected by pulmonary hypertension and worsening of asthma. Recent data from several laboratories demonstrate that obstructive sleep apnea is characterized by an inflammatory response. Cytokines are elaborated during the hypoxemic episodes leading to inflammatory responses as marked clinically by elevated C-reactive protein (CRP). As elevated CRP levels are considered markers of the acute phase response and characterize progression of vascular injury in coronary artery disease, it is likely that obstructive sleep apnea could lead to worsening of vasculopathy. Moreover, as inflammatory mechanisms regulate bronchial asthma, it is also likely that cytokines and superoxide radicals generated during hypoxemic episodes could exacerbate reactive airway disease. Patients with Cough, Obstructive sleep apnea, Rhinosinusitis, and Esophageal reflux clustered together can be categorized by the acronym, "CORE", syndrome. The purpose of this manuscript is to review the inflammatory responses that occur in patients with obstructive sleep apnea and relate them to the occurrence of cardiopulmonary disease.

We report a case of a previously healthy 41-year-old man who was admitted for progressive dyspnea and cough, which culminated in respiratory failure, shock, and death. Lung and muscle biopsy results were consistent with interstitial lung disease secondary to polymyositis. Polymyositis and dermatomyositis are rare autoimmune diseases that primarily affect the muscles and skin, with frequent extramuscular and specifically pulmonary manifestations. Respiratory complications are in 2 categories: primary (the interstitial lung diseases, which can be acute or chronic) and secondary (aspiration pneumonia/pneumonitis, muscle weakness, infection, drug-induced disease, pulmonary congestion secondary to heart failure, pulmonary hypertension, and pneumomediastinum). Diagnosis of a specific interstitial lung disease relies mainly on high-resolution computed tomography of the chest and on tissue diagnosis. Prognosis depends on the histopathology findings and the specific form of interstitial lung disease and its response to therapy, which consists of high-dose steroids and immunomodulating agents. Unfortunately, patients with polymyositis/dermatomyositis associated with pulmonary complications have a worse prognosis than patients with isolated forms.

The authors report the results of a study on patients with chronic cor pulmonale hospitalized in the Departement of Cardiology (Dakar), from 1990 to 1998. The hospital prevalence is 0.9% with a male predominance (73.5%). The clinical signs were dominated by dyspnea and cough. The right heart failure is noted in 85.29% of cases. As far as the biological factor is concerned, it exists an polycythemia about 75% of cases, hypoxia (88.8%), hypercapnia (55.5%) and a respiratory acidoses (55.5%). The spirometry showed in 66% of cases, a mixed syndrom with obstructive predominance. The echocardiography showed in all cases right heart dilatation with pulmonary hypertension. The etiological factors are dominated by tobacco (21 cases). The hospital evolution has been favorable in 19 cases underoxygentherapy, lowdosediuretic, expectorant, bronchodilatators and salt restriction. However, 14 patients have died.

Pertussis, or "whooping cough," is a highly communicable disease caused by the coccobacillus Bordetella pertussis. Pertussis remains one of the most common causes of death from infectious diseases worldwide. We describe a 5-week-old infant girl who presented with severe pertussis infection associated with extreme leukocytosis and required prolonged extracorporeal membrane oxygenation (ECMO). Nitric oxide therapy resolved the pulmonary hypertension, and she was successfully weaned from ECMO and discharged home after 3 months. We report successful application of ECMO for severe pertussis-induced respiratory failure despite multiple grave prognostic indicators (<1 year age, leukocytosis, pulmonary hypertension) and discuss the role of extracorporeal life support in treating pertussis.

Idiopathic nontransplant-related childhood bronchiolitis obliterans is an uncommon disease. Most patients present with chronic recurrent dyspnea, cough and wheezing, which are also features of asthma, by far a much more common condition. The present case study reports on a six-year-old girl who presented to a tertiary care centre with recurrent episodes of respiratory distress on a background of baseline tachypnea, chronic hypoxemia and exertional dyspnea. Her past medical history revealed significant lung disease in infancy, including respiratory syncytial virus bronchiolitis and repaired gastroesophageal reflux. She was treated for 'asthma exacerbations' throughout her early childhood years. Bronchiolitis obliterans was subsequently diagnosed with an open lung biopsy. She did not have sustained improvement with systemic corticosteroids, hydroxychloroquine or clarithromycin. Cardiac catheterization confirmed the presence of secondary pulmonary hypertension. Treatment options remain a dilemma for this patient because there is no known effective treatment for this condition, and the natural history is not well understood. The present case demonstrates the need for careful workup in 'atypical asthma', and the urgent need for further research into the rare lung diseases of childhood.
