The incidence of the germs appartening to the tribe of Mimeae yolited during acute respiratory affections was studied. The isolement of M. polymorpha and of H. vaginicola results positive in the 15% of the subjects examined and particularly during acute laringo-tracheobronchitis and hyperpyretical bronchopneumonitis. The pathogen function expliqued by Mimeae during the affections of respiratory system is important over all in regard of annexed therapeutical problems.

The AA. present the results obtained determining by the F.C. test the antibodies for respiraotry viruses and for Mycoplasma pneumoniae over 1112 patients, of which 742 affected with pathological respiratory processes, during the period 1971-1975. 104 patient have shown a significant correlation between respiratory disease and antibody movement for M. pneumoniae. They have been classified according to their clinical-radiological properties as follows: 38 affected with pneumonia; 37 affected with pleuritis; 29 affected with tracheobronchitis. Particularly interesting is the range of occurrence of the disease: we have noticed a high incidence in the period 1971-1972, followed by an almost complete disappearance of pathological instances in the period 1973-first semester of 1975, and signs of a new recrudescence in the second semester of 1975. These data have been confirmed also by investigations carried out among healthy people. It has also to be pointed out the possibility of family's epidemicity, and the AA. report two epidemic cases under personal observation.

Progressive pulmonary insufficiency appears to be a universal response to the lung to a variety of injuries which damage the pulmonary-capillary emdothelium. Persistent hyperventilation, unresponsive to the administration of oxygen, is the earliest clinical sign of this complication of trauma and should prompt close monitoring of pulmonary function (measurement of arterial blood gas and pH levels, Vd/Vt A-aDo2, minute ventilation, vital capacity and inspiratory force) to assess the severity of the disease, the need for mechanical ventilatory support and the effectiveness of treatment. Other pulmonary complications of burn injury range from carbon monoxide poisoning and narcotics overdosage in the immediate postburn period through marked hyperventilation directly related to burn size occurring in the absence of significant parenchymal change to later occurring hematogenous and airborne pneumonia. Inhalation injury, a chemical tracheobronchitis which significantly increases the mortality of a given-sized burn, may be present immediately postburn but clinically inapparent for 48-72 hours. 133Xenon lung scans permit early diagnosis of this pulmonary injury and the timely institution of a graduated therapeutic response keyed to the severity of pulmonary disability. Knowledge of the pathogenesis of each of these complications is requisite for the physician caring for burn patients and permits the employment of rational preventive and therapeutic measures.

The efficacy of respiratory support devices has been compromised by respiratory infection possibly related to the support mechanism itself. Differentiation between airway contamination (tracheobronchitis) and parenchymal infection (pneumonitis) is clinically significant, as is the differentiation of respiratory infection from other foci of sepsis in the complicated surgical patient. Serial quantitative tracheal cultures provide excellent objective measures of the presence, progression, and/or resolution of respiratory infection with few false positive or negative observations. Indeed, such observations often allow earlier definitive diagnosis of infection than can be achieved with conventional clinical, chemical, or roentgenographic studies. The method represents a useful supplement to the care of the patient requiring respiratory support when infection is a realistic possibility.

Two young children inhaled sweets which dissolved in the tracheobronchial secretions and caused severe respiratory obstruction. The viscid fluid produced as the sweet dissolved was not expectorated and bronchoscopy was necessary. The oedema of the mucosa caused by the presence of a hyperosmolar sugar solution took up to 48 hours to resolve; antibiotics and steroid cover were considered necessary. The similarity of presentation with acute tracheobronchitis and the lack of reports in the literature suggest that such cases may be misdiagnosed.

Graded concentrations of oxygen were used to establish dose-duration relations for the effect of oxygen on tracheal mucous velocity and tracheobronchial histologic findings in the anesthetized dog. Observations of tracheal mucous velocity were made during 30-hour periods of breathing air (100-percent humidified and warmed to 38 degrees C) and oxygen mixtures (also 100-percent humidified and warmed to 38 degrees C). In animals breathing oxygen mixtures, the baseline tracheal mucous velocity was taken as the value while breathing room air at the experiment's start. No statistically significant differences in tracheal mucous velocity occurred during air breathing. Tracheal mucous velocity fell 45 percent from the baseline value after breathing 100-percent oxygen for two hours (P less than 0.01), fell 42 percent after 75-percent oxygen for nine hours (P less than 0.01) and fell 51 percent after 50-percent oxygen for 30 hours (P less than 0.001). Histologic examination of the trachea and major bronchi after six hours of 100-percent oxygen and 12 hours of 75-percent oxygen revealed signs of acute tracheobronchitis. Minor histologic alterations in the tracheobronchial tree occurred both in animals breathing air and 50-percent oxygen for 30 hours; therefore, histologic evidence of oxygen toxicity could not be established at 30 hours. These findings indicate that in the anesthetized dog, oxygen depresses mucous transport as a function of inspired oxygen concentration (FIO2) and that even FIO2 as low as 0.05 might be deleterious.

The increased cultivation and sales of Euphorbia fulgens Karw., originating in Mexico, has in the last few years led to occupational allergy, type I, in three growers manifesting itself as nasal disease, tracheobronchitis or bronchial asthma. Intracutaneous tests with pollen extracts were positive in all cases, even at high dilution. A specific hyposensitisation regimen, conducted over five months, gave highly promising results in one patient who had no symptoms in the following season, despite similar exposure. Such sensitisation by pollens of Euphorbia fulgens Karw. is probably widespread among growers and florists. The allergen is found only in the pollen, not in other parts of the plant. There is no relation to the toxic substances in the milk-sap of this plant family (Euphorbiaceae).

Oesophageal perforations associated with cervical fractures occur from a variety of injuries. Fractures of the cervical spine, blunt trauma and penetrating injuries such as gunshot wounds, knives and missiles, perforate the cervical oesophagus. This retrospective study consists of 24 patients with an oesophageal perforation and cervical fracture. Motor vehicle accidents were responsible for 54% of the oesophageal perforations. The other oesophageal injuries were related to anterior spine surgery, gunshot wounds and sports-related activities. The clinical features related to these injuries included the obvious signs of an oesophageal perforation as well as fever of unknown origin, leukocytosis and unexplained persistent tachycardia. A variety of techniques was used to establish the diagnosis. All the patients had treatment for the cervical fracture and 20 patients required surgical repair of the oesophagus. The most common oesophageal complications were stricture of the oesophagus (54%) and oesophageal diverticulum (10%). The other complications were atelectasis, pneumonia, tracheobronchitis, pulmonary embolism, cervical osteomyelitis, cervical abscess, mediastinitis, septicemia and cervical fistulae. These patients have a serious life-threatening illness that may be difficult to diagnose and treat.

A retrospective study was performed in order to compare the clinical evolution of chronic bronchial asthma with onset in childhood with that of bronchial asthma registered at adult age. The group included 150 cases (87 females and 63 males) out of which 108 (72%) asthma with late onset and 42 (28%) asthma symptoms registered in childhood and adolescence. The symptoms were: allergic rhinitis and spastic tracheobronchitis in 18 (42.8%), dyspneic recurrent bronchitis in 16 (38%), nasal polyposis in 4 (9.5%) and atopic dermatitis in 4 (9.5%) cases. A possible allergic etiology was not taken into consideration in these cases. According to the data obtained, it results that the evolution and the prognosis of bronchial asthma are more severe in patients with its onset in childhood, where there were noted: more severe clinical forms of the disease, higher ventilation dysfunction, more numerous social (family) consequences of the disease, and a higher necessity of long term, systemic corticotherapy than in cases of bronchial asthma with late onset. The delay in the preventive treatment or an incorrect application of it in childhood will condition to a great extent the unfavourable evolution of the disease.

Although most new 'high tech' industrial processes are developed in industrialized countries, many of these technologies are eventually transferred to the industrializing countries. Many of these new technologies are associated with the use of respiratory toxins. However, there has been little study of acute or chronic health effects of work in these industries. The semiconductor industry illustrates many of these issues. The past decade has been increasing globalization of semiconductor manufacturing. Semiconductor manufacturing uses many chemicals with extremely high respiratory toxicity, including gases such as arsine and phosphine, strong acids and bases, dopants and photoactive chemicals. In semiconductor manufacturing, gases and chemicals are strictly controlled, but little is known about the occurrence of respiratory symptoms or disease in this industry. Potential acute respiratory effects of these exposures include mucous membrane irritation, tracheobronchitis, pulmonary edema and death. Chronic effects may include airway sensitization and possibly respiratory cancer. Movement of 'high tech' industries to less industrialized countries may not be accompanied by the same degree of attention to the control of workplace exposures. The shortage of adequately trained health and safety personnel, greater attention to safety than to health issues, and the unorganized and unskilled workforce in industrializing countries may exacerbate this situation. More research is needed on the health effects of exposures in rapidly changing industries such as semiconductor manufacturing, and the results of this research must be communicated and safe practices implemented worldwide.
