27 cases of uremia with abnormal appearances on the chest films were analysed. The results showed that the clinical features were cough, expectoration dyspnea and hemoptysis. However, the degree of these symptoms was relatively mild as judged from the amount of pulmonary edema found on the chest films. The chest X-ray finding in these group of patients were characterized by pulmonary blood stasis, interstitial edema of the lung and edematous alveoli. The pathogenesis of uremic lung was said to be related to blood urea nitrogen and creatinine retention and the concurrent presence of left side heart failure may also play a role. Hemodialysis and other comprehensive treatments could help the patients with uremic lung for relief the symptoms. But the fundamental managements to improve the prognosis for this disease are early treatment of the primary renal diseases, in order to prevent the occurrence of renal failure. Kidney transplantation should be advised.

Exercise and physical fitness are becoming increasingly popular in our society. As a result there are more individuals who are at risk for the development of acute respiratory emergencies associated with sports and athletics. EIB is a common feature of asthma and is characterized by a postexercise fall in FEV1 of more than 10 per cent. Although a variety of medications have been used for the prevention of EIB, cromolyn sodium and inhaled adrenergic agonists have been shown to be the most effective. EIA and cholinergic urticaria are two physical allergies in which hypotension can be brought on by exercise. In some individuals, EIA develops only in association with the ingestion of a particular food. Associated with sports and recreational activities in alpine areas is the risk of developing acute high-altitude medical problems. One of the most dramatic and potentially life threatening is high-altitude pulmonary edema. The management of this condition can be problematic, particularly if rapid descent to lower elevations is not possible. Although rare, spontaneous pneumothorax and pulmonary emboli do develop in the otherwise well-conditioned athlete. These entities must be considered when the physician evaluates any athlete in whom acute cough and dyspnea develop.

Nitrofurantoin is a widely prescribed antibiotic used for the treatment of urinary tract infections. In some patients it can produce an acute pulmonary reaction ranging from mild dyspnea to noncardiogenic pulmonary edema. Symptoms include fever, dyspnea, chills, cough, and chest pain. Physical examination generally reveals an acutely ill, extremely apprehensive patient in varying degrees of respiratory distress. Fever is usually present and there is an increase in heart rate and respiratory rate. Cyanosis, rales, and a maculopapular rash are common findings. Laboratory studies typically demonstrate a leukocytosis with eosinophilia, varying degrees of hypoxia and hypocapnia, and a mild to moderate elevation of the erythrocyte sedimentation rate. The chest x-ray study may be normal but more often demonstrates bilateral lower lobe interstitial infiltrates frequently accompanied by pleural effusions. Treatment in the majority of cases requires only stopping the drug, but steroids, bronchodilators, or antihistamines may be used in selected cases. Once the diagnosis is made and the drug withdrawn, prognosis for full recovery is excellent.

We present a rare case of aortitis syndrome associated with dilatation of aorta and coarctation-like effect due to the intraluminal flap formation originated from dissected wall of the aorta. A 31-year-old woman was admitted to our hospital complaining of shortness of breath, palpitation and cough. On admission, her physical status showed congestive heart failure and hypertension of upper extremities and hypotension of lower extremities. Bruits were audible over the neck, the anterior chest and the back. Serological studies showed active inflammation. Chest X-ray film showed upper mediastinal widening, cardiomegaly and pulmonary edema. Aortitis syndrome was strongly suggested by these clinical findings, so that prednisolone therapy was started on 3rd hospital day. Special examinations were performed several days later when inflammatory changes showed a tendency to improve. Chest CT scan, RI angiography and MRI studies showed an aneurysmal dilatation from the ascending aorta to the mid-thoracic aorta. Aortography demonstrated a flap at the terminal portion of this aneurysmal dilatation and grade II (Sellars) aortic regurgitation. There was a pressure difference of 80 mmHg between the parts abutting cranial and caudal sides of the flap. A surgical operation was, then, performed to correct the pressure difference. The dissected wall was extruded toward the aortic lumen creating a flap (2 cm in length). This flap was resected and an artificial graft was inserted. Histologically, the flap consisted of adventitia, media and intima.(ABSTRACT TRUNCATED AT 250 WORDS)

Two characteristics, volatility and biotransformation, make mercury somewhat unique as environmental toxicant, and make mercury poisoning as one of occupational diseases in the industry. Acute mercury vapor poisoning is a rare event. It often occurs during industrial accident or ignorant experiment. We report a case, a 28-year-old male waterworks technician, who developed dyspnea, cough, chest pain, metallic taste and ache in the whole body three hours after heating approximately 30 ml of liquid mercury during an experiment. Diarrhea with tarry stool occurred the next day. Chest roentgenogram revealed diffuse pulmonary infiltrates similar to pulmonary edema in both lungs, and was complicated by pneumomediastinum and subcutaneous emphysema later. The concentration of mercury in the plasma was over the toxic level. The urinary excretion of mercury greatly exceeded normal value. During hospitalization, the patient's liver and renal function tests were both normal. He was treated with penicillamine, 300 mg every six hours orally for 10 days in addition to a support treatment and oxygen therapy. He was discharged on the 15th hospital day with partial resolution of pulmonary infiltrates and was free of symptom.

197 cases of paediatric pneumonia from 2 hospitals were treated by Ning Fei Pian (NFP, the Lung Easing Tablets), a proprietary Chinese medicine for antipyresis, detoxication, blood invigoration, resolution of cough and phlegm; the control group was treated by penicillin, and the therapeutic results were comparable. Examinations of microcirculation and hemorrheology in the nailbed revealed improvements by NFP, which were conducive to the recovery of pneumonia. Electron-microscopically, the tablets also produced improvements in microcirculation, relief of lung edema, and the ratio of ventilation and blood flow.

The differential diagnosis of newly developed pulmonary infiltrate in CXR film of immunocompromised host including infection, neoplasm, pulmonary edema, pulmonary hemorrhage, cytotoxic drug induced pneumonitis, radiation pneumonitis and transfusion induced pneumonitis. If clinical course changed rapidly and the patient had fever, cough and dyspnea, then, opportunistic infection should be considered at first. Fiberoptic bronchoscopy with bronchoalveolar lavage (BAL), brushing and trans- bronchial biopsy (TBLB) will give most of informations. If the patient had hypoxemia, high, flow O 2 (even pure O 2) should be given to the patient and pulse oximeter used to monitor his state of oxygenation continuously. BAL should be done at first for its high yield in infectious cases. If the condition allowed us to perform more procedures, brushing and TBLB should also be considered. We present one case of polyarteritis nodosa with Pneumocystis carinii pneumonia after longterm endoxan and corticosteroid treatment. This patient had typical history and diagnostic procedures.

A 71-year-old man with a long-standing history of rheumatoid arthritis required methotrexate treatment since 1986, with a total dose of 210 mg. In April 1987, before arthroplastic surgery, methotrexate was discontinued. Four weeks later a syndrome of fever, dry cough, shortness of breath, and diffuse air-space consolidations on the chest radiograph evolved. An antibiotic therapy had no beneficial effect, and a bronchoscopy yielded no pathogens. An open lung biopsy led to the diagnosis of methotrexate-induced pneumonitis. This is the first report of a case where methotrexate-induced pneumonitis developed several weeks after cessation of the treatment. Methotrexate can cause four types of pulmonary adverse reactions: pneumonitis, pulmonary edema, pulmonary fibrosis, and pleuritis. Possible pathogenetic mechanisms, symptoms, treatment, and prognosis are discussed.

The interest in mountain tracking and climbing has increased and there is a need for knowledge of altitude-related diseases. About one million non-acclimatized individuals annually frequent areas around 2,000 to 3,000 m above sea level and incur unpleasant symptoms in the form of acute altitude sickness or potentially fatal conditions such as pulmonary and/or cerebral oedema. Headache is the most prominent sign of acute altitude sickness but fainting fits, loss of appetite, hesitant gait, euphoria, or confusion also occur. Dyspnoea, cyanosis at rest, and a dry cough are signs of pulmonary oedema. Cerebral oedema may be feared when inexperienced climbers are afflicted by severe headaches, vomiting, and hesitant gait. Coma ensues relatively soon. Treatment consisting in descent to lower altitude, administration of oxygen, and possible medicinal therapy is effective if immediately introduced.

The authors studied parameters of laryngopharyngeal (LPh) and tracheobronchial (TB) cough (the number of efforts--NE, the number of efforts per minute--NE.min-1, the intensity of the maximum effort--IME and the intensity of the attack--IA), respiratory parameters (VT, f, Cdyn), blood gas values (PaO2, PaCO2) and the pH in the arterial blood of anaesthetized cats (Pentobarbital Spofa, 35 mg x kg-1 i.p. with experimental pulmonary oedema. Oedema was induced by the i.v. administration of a fatty acid mixture (capric acid 3.8 g, caprylic acid 3.1 g and olive oil 3.0 g)--in a dose of 0.05 ml x kg-1 in group 1 and of 0.01 ml x kg-1 in group 2. Cough was elicited by stimulating the laryngopharyngeal and tracheobronchial mucosa with a silon fibre. Pulmonary oedema was determined from a macroscopic and microscopic examination of the lungs, from the ratio of lung weight to body weight and from the percentual dry weight of the right lungs. The authors found that the intensity of cough was depressed during pulmonary oedema, particularly in the case of TB cough. VT and Cdyn fell, f rose and the PaO2 and pH values steadily decreased.
