Clinical signs consistent with those of atypical interstitial pneumonia (AIP) were induced in calves sensitized with infective Ascaris suum eggs at seven to 20 weeks of age and challenged at three-week intervals one or more times. These signs usually appeared on the sixth or seventh day postinfection and reached maximum severity between the tenth and 13th days following infection. Prominent signs were: dyspnea, often with expiratory grunt, coughing, mouth breathing and emphysema as well as increased respiration and heart rates. In general, the intensity of signs was dependent upon dose size, although a single small dose resulted in acute signs and death in one calf. Intermittent coughing and vesicular sounds were induced in calves given A. suum eggs continually over prolonged periods. No respiratory abnormalities resulted from challenge with Toxocara canis after sensitization with A. suum. Antihistamine therapy did not alter the clinical signs in A. suum infected calves.

A 16-day infection of Dictyocaulus viviparus in two groups of calves was treated with levamisole and fenbendazole respectively. Five days afterwards the calves were reinfected with 4000 larvae and necropsied 21 days later. Although the lungworm burdens of the two groups of calves were reduced by about 70 per cent compared to a control group the clinical signs of dyspnoea, tachypnoea and coughing were indistinguishable from a primary infection. This was due to pulmonary emphysema, oedema and an acute epithelialising pneumonia apparently associated with the death and disintegration of lungworms in situ, the result of an incompletely developed immune response. The results are compared with those obtained with the lungworm vaccine. It was concluded that the outcome of any system of "control" which depends on drug therapy and reinfection is unpredictable and that vaccination offers the only effective method of prophylaxis.

Patients with respiratory disease commonly report that their sleep is disrupted by nocturnal cough. We have recorded cough during the night in 10 patients with severe chronic bronchitis and emphysema (forced expiratory volume in one second, 1.0 +/- SEM 0.1/L) who complained of nocturnal cough and correlated cough with electroencephalographic sleep stage and arterial oxygenation. Cough was recorded using a directional microphone and an auto-editing tape recorder system. Each cough was subsequently verified by a listener. There was a mean of 14.6 +/- 4.5 bouts of coughing per patient per night, each bout lasting on average 3.9 +/- 0.2 s. Eighty-five percent of coughing bouts occurred during electroencephalographically confirmed wakefulness (p less than 0.02 versus sleep), and coughs during true sleep were rare, with only 1 patient coughing during rapid eye movement sleep and none during Stages 3 and 4 sleep. Cough was only once followed by arousal. There was no correlation between cough and either apneas or hypoxemia during sleep. We conclude that spontaneous cough is suppressed during sleep and only rarely awakens patients.

Respiratory infections of 10 subjects with underlying respiratory diseases were treated with cefmetazole (CMZ) and its clinical effects were studied. Five subjects of them were respiratory tract infection, 3 subjects were pneumonia and 2 subjects were pneumonia followed by empyema. The underlying diseases were chronic pulmonary emphysema in 4 subjects, diffuse panbronchiolitis in 3, chronic bronchitis in 2 and bronchial asthma in 1. The doses of CMZ were 4 to 8 grams per day and the durations of administration ranged 3 to 39 days. The clinical effects were judged from the changes of fever, cough, amount of sputum, dyspnea, rale, chest X-ray, white blood cell counts, erythrocyte sedimentation rates, sputum culture and PaO2. The clinical effects of 6 subjects were evaluated as good, those of 3 were fair and that of 1 was poor. In 3 subjects H. influenzae in the sputum was eliminated and in 1 subject both H. aphrophilus and alpha-Streptococcus found in the pleural effusion were eliminated. In 1 subject Klebsiella in the sputum was eliminated and replaced by Enterobacter. No side effects were observed. We conclude that CMZ is considerably useful in the treatment of respiratory infections of the patients with underlying respiratory diseases.

Diffuse panbronchiolitis (DPB) is a disease with chronic inflammation exclusively located in the region of respiratory bronchioles. The pathologic features of the disease are characterized by thickening of the wall of the respiratory bronchiole with infiltration of lymphocytes, plasma cells and histiocytes, and extension of the inflammatory changes toward peribronchiolar tissues. In the advanced stage, secondary ectasia of proximal bronchioli may occur. These changes appear as diffusely disseminated small nodular shadows throughout both lungs on the chest roentgenogram. Obstructive respiratory functional impairment, occasional symptoms of wheezing, and also cough and sputum resemble the feature of emphysema, bronchial asthma, or chronic bronchitis, respectively. In the advanced stage, large amounts of purulent sputum and dilatation of proximal terminal conducting bronchioli resemble bronchiectasis. However, diffuse panbronchiolitis belongs to a distinctly different category from these diseases, and should be distinguished from them, because it may often show rapid progression with fatal outcome. The disease is dominant in males and the onset is unrelated to age. More than 1,000 cases of probable diffuse panbronchiolitis and 82 histologically-confirmed cases have been collected in Japan.

Because the diagnosis of extrinsic allergic bronchiolo-alveolitis is usually on a clinical and serologic basis, recent histopathologic descriptions of the syndrome are rare. As the etiology may vary in different countries, so perhaps may the histopathology? Clinical and serological examination was combined with histopathology of open lung biopsy from 14 northern Finnish patients. All of them, after exposure to mouldy dust, had a typical clinical syndrome with cough and/or dyspnoea, some radiographic changes, and a reduced VC and/or DCO. Precipitating antibodies were demonstrated in 11 patients. Histopathologically, oedema, macrophages and granulomas were found in all patients, as were lymphocytic and plasmocytic infiltrates. Inflammatory changes were alveolar, interstitial and bronchiolar, including bronchiolar granulomas in all but one case. None of the patients had severe fibrosis or emphysema. There were no examples of clear-cut acute or chronic stages as described in previous studies. Instead, most of our specimens represented an "intermediate" stage, indicating differences in exposure or susceptibility of the population compared with other countries.

A case of erythroleukemia coexistent with pulmonary emphysema is reported. A 67-year-old male was admitted to our hospital in May 1981, with a few year history of cough, sputum and fatigue. He had already been diagnosed as having pulmonary emphysema and moderate anemia. On physical examination, except for pallor, no other findings were remarkable. The initial hematological examination showed hemoglobin, 9.6 g/dl, red cell count, 251 x 10(4)/microliters, platelet count, 7.3 x 10(4)/microliters, white cell count, 2600/microliters with neither myeloblasts nor erythroblasts. A sternal marrow aspiration revealed 21% myeloblasts and 40% erythroblasts including 7.5% megaloblastoids. Periodic Acid Schiff staining was strongly positive for a part of erythroblasts. A chest X-P finding was typical for pulmonary emphysema. Pulmonary function was moderately damaged. He was started on chemotherapy with AAAP (ACNU 50 mg/d i.v. drip over 4 hr x 4d, adriamycin 20 mg/d i.v. push x 4d, Methotrexate 20 mg i.v. push x 4d). The first course of AAAP brought him a complete remission with both disappearance of myeloblasts and erythroid precursors with megaloblastoid nuclei in the marrow and the normalization of white cell count and platelet count in the blood. He was discharged in September 1981 after completion of a consolidation chemotherapy with AAAP. Since then, he received two courses of AAAP as an intensification chemotherapy and has been in complete remission for more than 13 months. His pulmonary function has not been affected and no myocardial damage has been seen throughout AAAP therapy. Thus, AAAP therapy seems to be an excellent chemotherapy even for an aged patient with erythroleukemia.

Five unusual cases of pneumomediastinum are described. In three the probable cause was thoraco-abdominal straining against a closed glottis during violent exercise, in criminal assault, or competitive sport. The resultant increase in intra-alveolar pressure produces an air leak which passes via the pulmonary interstitium into the mediastinum. It can then pass up into the neck to produce widespread subcutaneous emphysema and down through the diaphragmatic hiatuses to produce extraperitoneal emphysema. This may outline the lower surface of the diaphragm to stimulate intraperitoneal air, but it can also leak through the parietal peritoneum to result in actual intraperitoneal air. Therefore, in the patient who has been hospitalised after violent physical stress with or without blunt trauma, pneumomediastinum does not necessarily indicate tracheobronchial or oesophageal rupture and subdiaphragmatic air does not necessarily indicate bowel rupture. Probably any form of exercise in which the Valsalva manoeuvre is performed may cause pneumomediastinum, as may other causes of increased intra-alveolar pressure such as mechanical ventilation, bronchospasm, coughing and vomiting. Vomiting is a likely contributing cause in the pneumomediastinum of diabetic ketosis, of which a case is described. Another case is presented in which air passed in the opposite direction, from perforated extraperitoneal bowel up into the mediastinum.

Based on the technique described by Gabler et al. several years ago, stabilization of the mediastinum after penumonectomy is obtained by introducing a blown up latex balloon into the operated side of the thorax. The balloon is introduced immediately following surgery after being distended by means of Kuss's apparatus, and is removed, after being emptied in the same way, five to seven days later. Good stabilization of the mediastinum during the immediate postoperative period allows rapid effective coughing to take place. The balloon also prevents postoperative emphysema through the mediastinal and parietal walls, especially in enlarged excisions. The method is of undoubted value in the postoperative period following pneumonectomy, particularly in chronic bronchitis cases. No particular complications were observed.

Transtracheal aspiration (TTA) was performed 35 times in 33 patients with acute pulmonary infections. The indications for the procedure included pulmonary infection in immune-depressed or debilitated patients in whom the pathogenic organism could not be identified, either because of lack of sputum or suspected over-colonization of the oral cavity. The procedure was performed under full sedation with diazepam (Valium), by introducing a catheter (Intracath) through the cricothyroid membrane into the trachea, without local anesthesia. This modification markedly reduces the cough reflex and complications like subcutaneous emphysema and bleeding. Only two of our cases developed subcutaneous emphysema. The procedure enables the physician to make accurate and rapid therapeutic decisions and is recommended as a diagnostic tool.
