Relative to a particular level of female mortality, male mortality is lower than expected, currently and historically, in Northwestern Europe, Southeastern Europe, and Tropical Latin America; it is higher than expected in Western-Central Europe and in the Far East. The geographical pattern of differentials is attributable primarily to variation in the masculinity of mortality from cardiovascular diseases, neoplasms, and influenza/pneumonia/bronchitis. Over time, male mortality has increased relative to a particular level of female mortality, and these same causes of death are principally responsible. In the 1960's, high masculinity of mortality was associated independently with low proportions in primary activities, high proportions hiring in large cities, and with high discrimination against females in school enrollment combined with poor nutritional standards. The former two variables once again operate primarily through cardiovascular disease, neoplasms, and the respiratory diseases, whereas the discrimination-nutrition interaction appears to operate through infectious diseases. Variations in levels of economic modernization are capable of accounting for a substantial portion of the regional differences, although certain constitutional factors such as physiotype are also plausibly implicated, and they are also congruent with trends in sex mortality differentials.

Physiological conditions of respiration in children are defined especially by - relative hyperventilation because of high oxygen uptake per body surface, - relative narrow and soft airways with high tendency to obstruction, causing atelectasis, pneumonia or severe bronchiolitis. It is useful to differentiate between bronchiolitis and spastic or asthmatoid bronchitis, the latter being sensible to Adrenalin and developing to asthma of adults. Characteristical signs of asthmatoid bronchitis are bronchial hyperreactivity, increased airway-resistance and residual volume, decreased FEV 1, pulmonary compliance, arterial PO2 and PCO2 with signs of pulmonary inhomogeneity. Mucviscidosis, starting from abnormal viscosity of bronchial secretion, is functionally characterized by similar signs, so are increased RV with air-trapping, decreased FEV 1, VC, PO2a and pulmonary inhomogeneity. Diffuse progressive interstitial pulmonary fibrosis (HAMMAN-RICH) of acute type being mostly lethal in children up to 2 years of age and of subacute type in older children shows diffusion disturbance and characteristical ventilation disturbance with reduction of inspiratory reserve volume and enlargement of functional residual capacity but normal FEV 1. Disturbances are sensible to corticoid-therapy.

An attempt was made to determine the frequency of lung cancer occurrence in different inflammatory processes in the bronchi and pulmonary tissue. 100 cases of lung cancer were studied according to case reports and autopsy finding, the main tumor node and metastases were explored histologically. The data obtained indicated that in 2.2% of cases the development of cancer was preceded by influenza with residual phenomenon such as purulent bronchitis or pneumonia, in 2.3% of cases cancer occurrence was found to be dependent on chronic pneumonia. In 12.1% of cases cancer has arisen in fibrous-focal or cirrhotic tuberculosis with the presence of old caverns; in 14.7% of cases its development was related with pneumosclerosis and bronchiectases, and in 17.8% of cases it developed against the background of purulent bronchitis.

A 78-year-old man with pneumonitis and pulmonary abscess associated with Moraxella nonliquefaciens is presented. This organism was found by culture of both transtracheal aspirate and sputum. No previous reports have associated M nonliquefaciens with infection of the lower respiratory tract, although sinusitis and bronchitis have been reported. Possible predisposing factors in our patient included carcinoma of the larynx, as well as alcohol ingestion and cigarette smoking.

One hundred and fourteen refugee children from South Vietnam showed similar disease prevalences to refugee children from Bangladesh. Common diseases were malnutrition, gastroenteritis, pneumonia and bronchitis, scabies and furunculosis. Seven children died, five from pneumonia complicated by malnutrition. Increased awareness of the high incidence of Pneumocystis pneumonia and more careful assessment of nutritional status may reduce mortality in future groups of refugee children evacuated to Australia.

A study was carried out to determine whether the preexisting decline in mortality rates from infectious diseases accelerated after the introduction of antibiotic and chemotherapeutic drugs. Linear regression curves showed that in Sweden mortality rates declined faster in septicemia, syphilis, and non-memingococcal meningitis after the introduction of these drugs. By contrast, for the ten other infectious diseases studied, (scarlet fever, erysipelas, acute rheumatic fever, puerperal sepsis, meningococcal infection, bronchitis, pneumonia, tuberculosis, typhoid fever, and acute gastroenteritis) no such accelerated decline in mortality could be detected. The findings suggest that antibiotic and chemotherapeutic drugs have not had the dramatic effect of the mortality of infectious diseases popularly attributed to them.

In a study of a cohort of over 2000 children born between 1963 and 1965, the incidence of bronchitis and pneumonia during their first year of life was found to be associated with several family factors. The most important determinant of respiratory illness in these infants was an attack of bronchitis or pneumonia in a sibling. The age of these siblings, and their number, also contributed to this incidence. Parental respiratory symptoms, including persistent cough and phlegm, and asthma or wheezing, as well as parental smoking habits, had lesser but nevertheless important effects. Parental smoking, however, stands out from all other factors as the one most amenable to change in seeking to prevent bronchitis and pneumonia in infants.

We wanted to assess the relative influence of various personal and family factors upon the development of ventilatory function in young children. The relationship of several such factors to peak expiratory flow rates measured at the age of five years was studied in 454 children. These children were members of a birth cohort born between 1963 and 1965 in Harrow, north-west London, who were examined regularly from birth through the first five years of life. Beside its expected association with height, peak expiratory flow rate at the age of five years was also related to a lesser extent with peak expiratory flow rate in parents. Children with a history of lower respiratory illness had mean peak flow rates which were lower than those of children who escaped these illnesses. The earlier the onset of the illness and the more frequent its recurrence, the more marked its effect on ventilatory function. The group of children with a history of asthma and bronchitis had the lowest mean peak expiratory flow rate, but a history of bronchitis or pneumonia alone (that is, without asthma) was also associated with reduced ventilatory function. Respiratory illness beginning in the first year of life was the most potentially modifiable determinant of peak expiratory flow rate in children in this study.

Clinico-morphological and histochemical studies of changes in the lungs were carried out in 15 fatal cases of Wegner's granulomatosis. Morphological manifestations of the lesions consisted in bilateral extensive destructive-productive panangiitis in the system of bronchial, was well as pulmonary arteries and veins. As a rule, there developed an extremely polymorphic granular tissue which subsequently underwent necrosis with resulting cavern formation. Deep and sometimes irreversible changes observed in the vessels of the microcirculatory bed led to alveolar-capillary blockade and hypoxia, the latter culminating with circulatory crisis. Drastic dyscirculatory disorders were complicated with auto- and superinfection: development of destructive-suppurative bronchitis, peribronchitis, interstitial and also confluent pneumonia with "motley" exudate in alveoli, not infrequently with an abscess formation, sometimes with formation of hyaline membranes. The whole complex of these changes play a significant part in pathogenesis of pulmonary-cardiac insufficiency occurring in the majority of patients with Wegener's granulomatosis and often is responsible for fatal outcomes.

Crying ventilatory function was measured in 487 infants shortly after birth. Over the following five years 129 infants suffered attacks of pneumonia or bronchitis. Their initial crying ventilatory function was compared with that of the 358 infants who escaped these illnesses. No statistically significant differences were found in crying ventilatory function between these two groups of infants. This has been interpreted as indicating that newborn infants who subsequently suffer attacks of pneumonia or bronchitis do not start life with deficits in their ventilatory function. In the same study crying ventilatory function was measured in 550 infants at their first birthday; 70 had suffered attacks of pneumonia or bronchitis by that age and made a clinical recovery. Their crying ventilatory function showed no consistent difference from the 480 infants who escaped their illnesses. The reasons for the lack of a difference in crying ventilatory function is discussed.
