We report three elderly patients who presented with increasing dyspnoea on exertion and radiological evidence of basal bullous emphysema. On further investigation they were found to have alpha-1-antitrypsin deficiency. We emphasize that alpha-1-antitrypsin deficiency can present much later than is usually the case especially if the patient is a life-long non-smoker.

A retrospective review of 400 Chinese children who had inhaled foreign bodies was undertaken. There has been a yearly increase in the total number of cases of airway foreign bodies removed in our hospital. Fifty-eight percent of the children presenting were from the countryside; 42% were townspeople. Approximately 90% of the patients were under 3 years of age, with the peak incidence of foreign body inhalation occurring between 1 and 2 years of age (57.8%). The male-female ratio was about 1.2:1. About 95% of the removed foreign bodies were organic in origin. The majority of the foreign bodies were found most often in the right bronchial tree (46%). A positive history of foreign body inhalation was obtained in 98% of the cases. Twenty-eight percent of the children presented at the hospital within 24 hours, 71% within 1 week, and 29% more than 1 week after inhaling the foreign body. The most common presenting symptoms of laryngotracheal foreign bodies were cough, wheezing, dyspnea, and hoarseness; those of bronchial foreign bodies were cough, wheezing, decreased air entry, and rhonchi. More than two-thirds of the children with larygotracheal foreign bodies had normal x-ray findings. The most common fluoroscopic findings in those children with bronchial foreign bodies were mediastinal shift (36.8%), obstructive emphysema (35.7%), and normal findings (35%). A total of 348 (87%) bronchial foreign bodies were removed by rigid bronchoscopy (81%), rod-lens bronchoscopy (5%), and spontaneous expulsion (1%); 52 (13%) laryngeal and tracheal foreign bodies were removed by direct laryngoscopy (12%) and tracheotomy (1%). A single endoscopic procedure successfully removed 92.5% of 400 foreign bodies detected in the airways. One child died during bronchoscopy, for a mortality rate of 0.25%.

The experience of diagnosis and treatment in 15 patients with mediastinal abscess was introduced in this paper. Most mediastinal abscesses are the results of secondary infection. One of the main causes is esophageal perforation. The main clinica manifestations are fever, chest pain, dysphagia and dyspnea. A toxic shock develops in serious cases. Chest X-ray examination is an important diagnostic method showing widened mediastinum, air-fluid level in mediastinum and subcutaneous emphysema. The writer holds that once diagnosis is made, an adequate drainage of abscess should be made by individualized route of entry. In order to maintain enough nutrition, gastrostomy should be performed followed by tube feeding. In this series, the above mentioned treatment regime gave quite satisfactory result. Twelve of the 15 cases got cured or improved. Three cases failed to respond and died.

A 68 year-old white male patient with previous diagnosis of pulmonary emphysema was submitted to acupuncture. The needles were inserted into the precordial area and the patient immediately complained of worsening dyspnea. Four days later pneumothorax was detected by chest X-rays. A thoracic tube was inserted with total lung expansion.

The long term outcome for 88 patients with bullous emphysema who had operations was analysed from the clinical, respiratory function and occupational point of view. In order to reduce to the minimum any bias which would be likely to appear as a result of a decrease in the number of patients with time respiratory function parameters were compared to those of a restricted number of patients for whom we knew all the values for each period determined. Before the operation all the patients showed radiological signs of bullous emphysema; the respiratory function measurements in 66 of them showed bronchial obstruction with distension, hypoxaemia at rest without hypercapnia. The clinical follow up and respiratory function was spread over more years. It showed a post operative improvement in dyspnoea which was perceptible in 77% of patients at 2 years, 68% at 3 years, 60% at 4 years, 51% at 5 years, 32% at 10 years. 2/3 of the patients who were working before the operation had taken up their normal work following it. the survival levels were 86% at 1 year, 83% at 2 years, 80% at 3 years, 78% at 4 years, 77% at 5 years, 73% at 6 years, 73% at 6 years, 58% at 10 years. Of 20 patients who died 12 had died of respiratory failure. All the spirographic parameters had improved following the operation but a secondary deterioration was noted around the 5th post operative year for the vital capacity, and at the third year for residual volume, FEV 1, and the FEV 1/VC ratio as well as PAO2.(ABSTRACT TRUNCATED AT 250 WORDS)

Severe alpha 1-antitrypsin (AAT) deficiency is a relatively common inherited condition in populations of Northern European heritage. Current estimates of the prevalence of the PiZ phenotype range between 1/3500 and 1/1670 in the United States. Clues to the whereabouts of the undiagnosed individuals with severe hereditary AAT deficiency can come from the existing information about the natural history and clinical course of disease. In the PiZ smoker, dyspnea develops soon after age 30 years or at least before age 40, and death from emphysema is likely by age 50. The PiZ nonsmoker has a prognosis only marginally worse than that of the susceptible smoker without AAT deficiency. Dyspnea often does not appear until after age 50 years, and clinically significant emphysema not usually until after age 60. All infants presenting with liver disease in the neonatal period should be tested for the deficiency. In adults, clinically significant dyspnea in the 30s and 40s, in association with abnormal lung function, should raise the suspicion of AAT deficiency. In nonsmokers, dyspnea at any age justifies further investigation. A serum AAT level below 80 mg/dl (11 microM) is considered abnormal; individuals falling in this range should be phenotyped. The formation of a Registry for severe hereditary AAT deficiency in the United States, under the auspices of the National Heart, Lung and Blood Institute of the NIH, is also described.

Chronic irreversible obstructive airways disease (COAD) is the end result of a number of disorders: airway damage from tobacco smoke, atmospheric pollution and occupational dust and fume, bronchiectasis, cystic fibrosis, bronchial asthma and a number of congenital disorders of defective airway defence. The clinical features include sputum, wheeze, breathlessness and infective and noninfective airway inflammation. The pathological consequences are airways obstruction, emphysema and respiratory failure. Except in bronchiectasis, the volume of daily sputum and bronchial infection is less than 20-30 years ago. At autopsy, bronchial gland hypertrophy is now an inconstant feature. Bronchial infection probably contributes little to airways obstruction, but the load of activated neutrophils in bronchiectasis is an important feature. Wheeze comes late to many patients with COAD. It is associated with less reversibility to bronchodilator drugs and more fixed airways obstruction compared to the conventional asthmatic and is probably of different aetiology. Breathlessness is of variable severity when the forced expiratory volume (FEV1) falls below 1.0 liters resulting in disability ranging from manageable to severe. The FEV1 declines an average by 70-80 ml/year (normal approx. 25 ml/year) until the value falls below 1.0 liters, then the rate of decline slows to a plateau which can persist for several years. During this period, hyperinflation, breathlessness and respiratory failure continue to worsen. Significant respiratory failure may be a terminal event or be present for many years. Arterial oxygen tension (PaO2) slowly declines in most patients--"pink puffers" generally have a minimal rate of fall until weeks or months before death, "blue bloaters," by contrast, several times as great.(ABSTRACT TRUNCATED AT 250 WORDS)

76 year-old man was transferred to emergency room because of severe epigastralgia and dyspnea. He was well until 5 hours before admission, when he suddenly felt severe epigastralgia followed by vomiting. He was found to be in warm shock state. Chest X-ray film showed dilation of mediastinum, pneumo mediastinum, left pleural effusion and subcutaneous emphysema, which were consistent with esophageal perforation. Esophageal contrast study was diagnostic. Emergency operation was performed in which rupture of the lowest esophagus causing remarkable mediastinitis and pleuritis was observed. Esophageal tear was primarily closed and chest drains were placed. Despite severe post-operative complications, he was discharged with recovery 5 months later.

The efficacy and safety of almitrine bismesylate, a new respiratory stimulant, in patients with the hypoxaemic form of chronic respiratory insufficiency caused by chronic bronchitis and emphysema has been assessed. The multicentre trial of 12 weeks duration was double-blind and placebo controlled, with individual and group comparisons. Twenty three patients received almitrine 50 mg b.d. p.o. and 17 took placebo. In the almitrine group a significant increase in PaO2 was achieved (control value 54.4 mm Hg, rising to 59.1 mm Hg after 6 weeks, and to 59.4 mm Hg after 12 weeks). There was also a significant decrease in PaCO2 in the almitrine group after 12 weeks. No correlation was found between the plasma almitrine concentration, PaO2 and PaCO2. Lung function (FVC, FEV1, FEV1/FVC, Raw, TLC, RV, FRC) did not change in either group, but the degree of dyspnoea and performance in the 6 min walking test were significantly improved in the almitrine group. Adverse reactions appeared in 6 out of 23 patients on almitrine bismesylate (headache, urticaria, breathlessness, diarrhoea, chest pain, nausea and vomiting), causing drop out of 4 patients. Thus, almitrine bismesylate can be considered useful in the treatment of patients with chronic respiratory insufficiency.

States of airflow obstruction are common disorders which span the spectrum from asthmatic-chronic bronchitis to emphysema. Asthmatic and chronic bronchitic states are at least potentially reversible by systematic, pharmacologically oriented therapy focusing on bronchodilators and corticosteroids. Both asthmatic bronchitis, particularly when it is not adequately treated, and emphysema result in the final common pathway of COPD. These are generally progressive states, unless smoking cessation can be achieved in early or mild stages of disease. The future focuses on the great challenge of early identification, classification, and intervention. Thus, all patients with cough, dyspnea, and wheeze should be carefully evaluated by health workers who understand the history, physical examination, and simple pulmonary function tests in the context of chest radiology. These clinical methods together can help define the disease states characterized by airflow obstruction. Often, a final definition of disease cannot be made until aggressive attempts at the treatment of the airflow obstruction and its attendant symptoms complex have been vigorously pursued by experienced clinicians.
