There is increased recognition of hypersensitivity lung disease among workers with laboratory animals as an occupational disease. Symptoms of asthma in 44 of 78 workers with laboratory animal dander allergy reflected the serious consequences of this occupational ailment. Affected employee profiles induced family history of atopy; immediate (Type I) allergic reaction; symptoms of rhinitis, asthma, and cough; hypersensitivity to one or more species, most often rats, mice, and rabbits. Diagnosis depends on history and physical, radiologic, and laboratory examinations, including skin tests with relevant antigens. Control and treatment depend on environmental change (reemployment or reduction of antigen contact); mechanical devices (masks and filters); chemotherapy (bronchodilators, steroids), prophylaxis and immunotherapy (hyposensitization). Standardization of medico-legal criteria covering occupational asthma is needed.

Extensive resection of the abdominal wall was performed on six patients to reconstruct defects caused by tumors or necroses. Autologous dermis covered by a flap plasty produced good clinical and functional results, documented by the measurement of intraabdominal pressures in response to coughing, pressing, and lifting of the legs. The autologous dermis graft represents a valuable tool for the closure of large defects of the abdominal wall.

A prospective study of 125 chemical workers was carried out for ten years to investigate the incidence of lung cancer. Some of the men were exposed to chloromethyl methyl ether containing bis(chloromethyl) ether as an impurity. Bronchogenic carcinoma was markedly increased among them, with a strong dose-response relationship. An unexpected inverse relationship was noted between smoking and the incidence of lung cancer. The neoplasms (all small-cell carcinomas) occurred in relatively young men. Symptoms of chronic bronchitis were reported more often among men exposed to chloromethyl ether, and a dose-response relationship was apparent, with smoking a cofactor. Ventilatory function was not significantly affected by chemical exposure. Periodic screening over the first five years of the study showed a decrease in chronic coughing and an increase in dyspnea while chemical exposure was diminishing.

Three cases illustrate the principal clinical and roentgenographic varieties of granular cell myoblastoma (GCM) of the lung. The vast majority are small benign intrabronchial tumors without roentgenographic findings. These remain asymptomatic and are detected accidentally at autopsy, surgery, or bronchoscopy (Case III). Larger obstructing lesions (Case I) cause focal atelectasis or pneumonitis, leading to cough, expectoration, and hemoptysis. Hilar enlargement from reactive lymph node hyperplasia is common. Clinically and roentgenographically these are indistinguishable from bronchial adenomas. Least often the tumor extends entirely extrabronchially (Case II) presenting as a parahilar parenchymal asymptomatic nodule, simulating a granuloma, hamartoma, arteriovenous malformation or a neoplastic nodule.

Three different low pressure cuffed endotracheal tubes (Lanz, Portex soft-seal, Kamen-Wilkinson) were studied in cadaver tracheas and patients in our intensive care unit during ventilation. In the air filled low pressure cuffs without controlled pressure system the cuff pressure and the ventilation pressure are almost identical. Rises of intrathoracic pressure during mechanical ventilation are reflected by increased cuff pressure. Tubes with controlled pressure system or foam-filled cuffs have lower peak cuff pressures, especially during sighing, coughing and suctioning.

1. Mucociliary clearance has been measured over a 6 h period by using the radioaerosol technique in seven normal male subjects lying supine, both during the day when awake, and during the night when asleep. 2. The percentage of radioaerosol cleared during the night, when asleep, was significantly less than during the day when awake (P less than 0.02). 3. A comparison of radioaerosol clearance before and after the time of onset of sleep demonstrates that reduced clearance occurred during sleep, indicating that this is probably a sleep-related phenomenon and not merely a result of diurnal variation. 4. This finding has important implications for patients with chronic bronchitis or asthma, in whom early morning cough or wheeze may be a predominant feature.

The results of a respiratory questionnaire and spirometric tests of 133 ex-smokers out of 649 male public servants aged 15--64 years have been analysed. When the population was adjusted for age, height and the presence or absence of chronic respiratory symptoms the FEV1 of the ex-smokers had not returned to normal but fell between that of the light (less than 10 a day) and moderate cigarette smokers. Factors contributing to this have been investigated. Factors affecting the FEV1 of the ex-smokers were found to include duration of smoking, quantum smoked and years since smoking ceased. An interactive effect has been demonstrated between quantum smoked and duration of smoking such that ex-smokers who used to smoke 10 or more cigarettes a day for more than 10 years had the lowest lung function but duration of smoking was not important if less than 10 cigarettes a day had been smoked. Only just over a third of the ex-smokers gave health related reasons for giving up smoking, a proportion which is considerably lower than has been found in other studies. Possible reasons for this difference are discussed. As in other studies less than 10 percent gave up smoking because of its cost. Respiratory screening to include questions on cough, phlegm and wheeze together with measurement of the FEV1 is an important way of demonstrating to individual smokers evidence of any damage caused by their smoking.

The effects of orally ingested dihomo-gamma-linolenic acid (DHLA), the natural biosynthetic precursor of prostaglandin E1 (PGE1), were assessed in human volunteers. Single doses of DHLA (0.1--2g) increased the proportion of DHLA relative to arachidonic acid in plasma and platelets and also increased the ex-vivo capacity of platelets to produce PGE1 and PGE2. More pronounced effects were observed during sustained treatment (five days to four weeks) when DHLA also accumulated in red cell membranes. These biochemical changes were accompanied by potentially antithrombotic changes in haemostatic function. The most common effect, which was consistently detected after 0.1-g single doses of DHLA or its methyl ester, was a decrease in plasma heparin-neutralising activity. Inhibition of platelet aggregation induced by adenosine diphosphate was also detected, though this was generally less pronounced. Sustained treatment in one subject also produced definite inhibition of ristocetin-induced platelet aggregation. There was only one possible adverse effect--a transient cough in a subject with a history of asthma. DHLA therefore seems to have considerable potential as an agent for preventing and treating human thromboembolic disease.

Our data in 74 patients demonstrate that procaine hydrochloride is a safe anesthetic adjuvant in doses of 1 mg/kg/min even when total doses are 5 to 7 g. Blood pressure, heart rate, electrocardiographic variables, and blood gases were not adversely affected. Patients had no nausea or untoward postanesthesia symptoms. Emergence from anesthesia was rapid, within less than 15 minutes in all patients, and most were fully awake before leaving the operating room. In two patients in whom blood levels were studied the drug disappeared within 40 minutes. Procaine is inexpensive, $1.16 for 10 g, and it is not a known liver or kidney toxin. Until studies on cardiovascular dynamics and analgesic effects as in whom a low plasma cholinesterase activity is present or suspected. The clinical appraisal in 56 patients indicates its usefulness in suppressing premature venticular contractions and cough reflexes during endoscopic procedures in the respiratory tract. Procaine can be used to advantage in supplementing general anesthesia in outpatient surgery because of its brief action. For these reasons, the drug merits further study.

Laryngotracheobronchitis (LTB) continues to occur in epidemics necessitating many hospital admissions. A short barking cough, stridor with a crowing sound on inspiration, and retractions of the intercostal respiratory muscles are hallmarks of the disease. LTB is most frequently a viral disease causing acute inflammation of the subglottic area, the trachea, and the segmental bronchus. Increasing subglottic edema and generalized fatigue of patients with this disease can cause progression of airway obstruction. Respiratory and cardiac arrest follow unless an immediate airway is established. The management of LTB is primarily medical and consists of moist air, sedation, close observation, and occasionally antibiotics. Patients with respiratory difficulties severe enough to require intubation should undergo direct laryngoscopy and bronchoscopy to rule out other causes of airway obstruction.
