Pulmonary diffusive capacity by the carbon monoxide method was evaluated in 43 patients two years after myocardial infarction, and without evidence of other types of heart disease. The patients did not have primary lung disease or clinic bronchitis. Special interest was given to the effects of cigarrette smoking and moderate pulmonary congestion. A significant decrease in diffusion capacity was observed in smokers and former smokers compared to none smokers. In moderate pulmonary congestive the oposite effects was registered. pO2 was decreased in half the patients with old myocardial infarction but there was no significant statistical correlations with D1co values. Mean values for pO2, pCO2, pH, EB did not show statistically valid differences among the subgroups under study. Different factors which may influence the evaluation of diffusion capacity are discussed.

380 athletes in optimal performance were examinated within 10 years between 2 and 13 times (average: 4 times): ECG were taken at rest, during breathing tests and under maximal physical load by ergometry. 88 (23.2%) of them showed arrhythmias, 32 in the same examination different forms of premature beats. All kinds of arrhythmias were seen except atrial flatter, total av-block and paroxysmal tachycardias. Breathing tests provoked most of arrhythmias followed by the recovery after maximal physical load. Follow-up studies and clinical examinations proved that in 86 sportsmen these arrhythmias were not a symptom of heart disease. Only in 2 athletes heart injury could not be excluded. But in nearly 50% extracardial inflammations, like tonsillitis, bronchitis etc., were found. It is discussed that bradycardia and vagotonia of the highly trained sportsmen cause the arrhythmias. This vagotonia is intensified by breathing tests. But arrhythmias found in athletes should cause an examination for other chronical sicknesses.

Schizophrenia has been defined as an indentifiable disorder based on phenomenologic classification. Support for this concept is derived from consistent observations of a low frequency of the disorder in general populations throughout the world but substantially higher frequency of occurrence in siblings of affected individuals. The rates of concurrence in diagnosis for schizophrenia, surprisingly, vary in similar degree to those found for a series of physical disorders such as cervical cancer, emphysema and bronchitis, and electrocardiographic evaluations of cardiac disorder. The most recent findings from cross-national diagnostic studies of mental disorder uphold the need for a regular, more definitive classification system that is considered from both the service and research points of view.

Twenty-eight children with Down syndrome (DS) and acute lymphocytic leukemia (ALL) were compared to non-DS control leukemics matched by age, white blood cell (WBC) count, and treatment protocol to evaluate presenting manifestations, toxicity, and outcome. The DS children with ALL did not have unique clinical or biologic characteristics to distinguish their disease from that of non-DS patients. Eleven of the DS patients had successfully banded cytogenetic studies of their leukemic cells with the distribution of model chromosome number of 46 (n = 1), 47 (2), 48 (5), and greater than 50 (3). The abnormal leukemic line involved an isochromosome of the long arm of chromosome 9[i(9q)] in 3 cases. Multiagent chemotherapies induced complete remissions in 25 patients (85%), yet overall 5 year event-free survival was only 23 +/- 8% when compared to 64 +/- 9% for control children receiving similar therapies (P less than 0.01). A significant cause of treatment failure was late marrow recurrence in the DS children. Host toxicity was striking in these children. Severe congenital heart disease present in one-third contributed to 2 deaths during antileukemia therapy. Hyperglycemia secondary to diabetogenic agents and repeated bronchitis were common toxicities. Intolerance to the antifolate methotrexate with severe gastrointestinal and skin toxicities was universal. We conclude that the poor prognosis for the child with DS and ALL stems in part from their increased risk of complications and toxicity from intensive modern leukemia therapies, specifically antifolates.

Non-drinkers and heavy drinkers tend to have higher total and cardiovascular mortality rates than light or moderate drinkers. The finding is not disputed; it is the interpretation of this U-shaped curve that is controversial, and in particular the belief that light and moderate drinking protects against coronary heart disease. The British Regional Heart Study of middle-aged British men has shown that 70% of non-drinkers are ex-drinkers. Those ex-drinkers have high rates of doctor-diagnosed illnesses including heart disease, hypertension, diabetes and bronchitis as well as high prevalence rates of measured hypertension, obesity, current smoking and regular medical treatment. Over a five-year period men who were diagnosed as having heart disease, had multiple diagnoses or were put on regular medication had an increased likelihood of becoming non-drinkers or occasional drinkers. The study suggests a downward drift from heavy and moderate drinking towards non-drinking under the influence of accumulating ill health. The data strongly suggest that the observed alcohol-mortality relationships in prospective studies are produced by symptoms and disease present at the time of screening, and by the prior movement of men with such disorders into non-drinking or occasional drinking categories. The concept of a protective effect on mortality which ignores the dynamic relationship between ill health and drinking behaviour is likely to be ill-founded. A review of the major prospective studies reveals an inadequate exploration of the nature of non-drinkers, who are clearly unsuitable for use as a baseline in studies of the effects of alcohol on health.

Deadspace is defined in terms of the efficiency of the lung in eliminating carbon dioxide. The airway deadspace is the volume of the airway in which gas moves chiefly by convection. The alveolar deadspace is caused by ventilation/perfusion inequalities at the alveolar level. The commonest causes of increased alveolar deadspace are airways disease--smoking, bronchitis, emphysema, and asthma. Other causes include pulmonary embolism, pulmonary hypotension, and ARDS. In addition, right-to-left shunting (cyanotic heart disease, atelectasis) causes an apparent or virtual deadspace, which, although not representing non-perfusion of any compartment, nevertheless reduces the efficiency of ventilation.

Nine cases of respiratory infections caused by syncytial respiratory virus which were diagnosed by direct immunofluorescence with monoclonal antibodies are presented here. Six of them have been clinically diagnosed as bronchiolitis and the remaining three are diagnosed as obstructive bronchitis, upper respiratory cold and respiratory distress respectively. Seven are male and two are female. Their ages vary from 13 days to eleven months. Its usefulness is indicated given its speed and the current availability of specific antiviral therapeutics. The test would be especially indicated in atypical cases like nursing babies with apnea or those with congenital heart disease or other underlying lung diseases and also to prevent intrahospital epidemias. The conclusion is reached that direct immunofluorescence seems to be an attractive alternative for laboratories that do not have costly cell culture equipment.

During a winter epidemic, 87 infants were admitted to Necker-Enfants-Malades hospital with a severe respiratory syncitial virus (RSV) infection. These infants fell into two groups: 37 infants without any medical history and 50 showing an underlying pathology (immune deficiencies, heart disease, CNS disorders, digestive malformations, allergic manifestations). Of the 37 infants with no medical history, most were below the age of 6 months and the RSV infection was manifested clinically by bronchiolitis or bronchitis. Most of the infants in the other group were more than 6 months of age and presented mostly with pneumonia or bronchiolitis. A respiratory distress syndrome was observed in 17 of the 87 infants, and virtually all of them were younger than 6 months. No significant difference was observed between the two groups with regards to the incidence of respiratory distress. Pulmonary infections complicating the course of the illness, most often due to commensal flora bacteria of the upper respiratory tract, were observed in 19 infants but with no greater frequency in the group at risk. Direct detection of viral antigens in nasopharyngal secretions not only enabled rapid diagnosis in all the infants but also allowed antiviral therapy to be started rapidly. Antiviral treatment by ribavirine, administered over a period of 5 days in 20 mg/ml doses by aerosol was instituted in 10 patients whose course might have become serious. In 8 of these patients, disappearance of the virus from secretions and recovery occurred. Two patients in the group at risk died despite treatment, with one case being considered a true therapeutical failure since the virus was still present in nasopharyngeal secretions.(ABSTRACT TRUNCATED AT 250 WORDS)

A study of the geographical distribution of cerebrovascular disease in Scottish communities during three quinquennia between 1959 and 1983 showed a marked tendency for high SMRs to be present in the west of Scotland and low SMRs in the east. Cerebrovascular disease was significantly correlated with coronary heart disease, with bronchitis, emphysema and asthma, and to a lesser extent with other heart disease, with other circulatory disease and with indices of overcrowding. It was not associated with either urbanization or industrialization.

16 patients of the Medical ambulatory at the University of Basel born between 1940 and 1945 were explored with the State-Trait Anxiety Inventory (STAI) of Spielberger for the presence of anxiety. With this self-rating inventory state anxiety as well as general trait anxiety can be recognized. The examined group was not selected on specific diagnoses. Two patients with a heavy organic disease (Aids, Friedreich's ataxia) showed an increased state anxiety and an increased general trait anxiety. Six patients with hypertension showed decreased, average as well as increased values of state anxiety and general trait anxiety. In one patient with epilepsia decreased general trait anxiety and average state anxiety were manifest. A patient with a depressive neurosis and functional abdominal pain showed increased general trait anxiety and average state anxiety. Finally, in six patients with different diseases, such as patients with different diseases, such as bronchitis, diabetes, coronary and congestive heart disease, obesity and myalgias, no deviation of their state and general trait anxiety values was evident when compared with standard values. The results are discussed.
