[Liaison psychiatry: a new perspective on mental health in Latin America].

The situation of Mental Health in Latin America is analyzed. Urgently creating a system able at handling the psychiatric disease increase in the years to come is a conclusion this paper strongly aims at. The beginning of Psychiatry is reviewed, and the importance of Psychiatry at the General Hospital is outlined as well as its rapprochement toward the community, which led to a better control and prevention in the field of Mental Health. A definition of Psychiatry is proposed, as a branch of Medicine which stands in between mental hospitals and communities. Active teamwork, coupled with the physician's work and the tasks other members of the health personnel are engaged in, has led to a more integrated approach onto the ill thus benefiting not only patients but also the whole community.

[Emphysematous cystitis].

Emphysematous cystitis constitutes an uncommon clinical radiological entity. (Approximately 160 cases in the literature). We offer five cases of emphysematous cystitis, all of which occurred in women aged 60-80 (X = 74.2). All of them except one proved to be known diabetics and the glycemia figures at the time of being attended were above the limits of normality. In no case was pneumaturia observed, and the main symptoms displayed were those of the cystitis type together with pain in the hypogastrium and macroscopic hematuria. Simple abdomen radiology was the diagnosis procedure in all cases. The treatment applied permitted the favourable evolution and resolution of the process.

Immunologic parameters in atopic dermatitis.

In view of the lack of agreement among the various authors regarding the pathogenesis of atopic dermatitis (AD) we decided to conduct an immunological study on patients affected by atopic dermatitis, whether associated with allergic respiratory disease or not. Twenty five patients were studied using T lymphocytes and their subpopulations, the lymphoblastic transformation test and serum immunoglobulin parameters. We found a decrease in the T mu/T gamma ratio in patients with pure AD relative to those with associated respiratory disease as well as a direct correlation between the T mu/T gamma ratio and IgE, which support the role of the T regulatory system in IgE production.

Carbuterol, salbutamol and DSCG in exercise-induced asthma.

We decided in this work to evaluate the prophylactic value of carbuterol in exercise-induced asthma (EIA), comparing this drug to salbutamol and DSCG in order to describe its usefulness in exercise-induced asthma, while employing the closing-pressure method for the early detection of airway constriction. The study involved 44 bronchial asthmatics with prior histories of EIA. Only 10 patients had noticeable symptoms after exercise. All patients were asymptomatic and without any medication for at least one week prior to the commencement of the study. A continuous running treadmill was chosen for the exercise test, and a 10 minute time-period with a maximum heart rate of 180 beats/min. was the limit. Measurements of the FEV1, PEF and Raw were also done. Drug therapy was carried out by administering 10.5 mg of carbuterol, or 4 mg of salbutamol orally, 1.5 hours, before the exercise, or a 20 mg DSCG capsule, 30 minutes also prior to exercise. We concluded that: DSCG is the drug of choice in the control of EIA, while salbutamol results were somewhat less effective. Orally administered carbuterol did not provide any protection effect as expected. Raw measurements enter as a new parameter for consideration in this type of disease, being entirely compatible with FEV1 and PEF values during assessment.

Standardized values of lower airway resistance in healthy individuals.

One hundred and seventy eight healthy individuals, smokers and non-smokers of both sexes were studied, grouping them according to the parameters of age, height, weight and body surface, with the aim to prepare a standard table of airway resistance. The method was performed with the apparatus APTA (Jaëger) based upon the closing pressure technique. Regarding resistance, the average value obtained was 0.66790 Kpc/L/sec-1 with a standard deviation of 0.26773. With respect to the statistical study, no significant correlations were found among the parameters of sex, age, weight, body surface and smoking habits in relation with airway resistance. Nevertheless, we obtained an inverse significant correlation between variables of height and airway resistance. As a consequence, a study of linear correlation was done between height and airway resistance, bringing about the correlation coefficient such as the equation of linear regression wherein we obtained the lines of regression and the formula of the equation.

Airway resistance in bronchial asthma and rhinitis.

Following the acceptance of the interrupter technique as one of the most sensitive in determining airway resistance, we decided to conduct a comparative study between healthy subjects and those patients with respiratory illness, in the varieties rhinitis and bronchial asthma. The study included 125 patients with respiratory illness, 42 diagnosed as having rhinitis and 83 with bronchial asthma with or without associated rhinitis. These groups were divided into symptomatic and asymptomatic at the time of the study. Hundred and eighty individuals were selected as a control group. A significant difference can be seen between the values for airway resistance of the control group (means = 0,651 7 kpc/l./sec.-1) and those with symptomatic rhinitis (means = 0,7732 kpc/l./sec.-1) or symptomatic bronchial asthma (means = 1,2602 kpc/l./sec-1). Values for airway resistance in asymptomatic patients (rhinitis and bronchial asthma) are similar to the control group. The rhinitis group which was clinically symptomatic at the beginning of the study was divided into two groups according to whether the airway resistance was within +/- 1 standard deviation of the mean or elevated analysis showed a statistical difference between the two groups. This makes us think that we are dealing here with distinct groups.

Study of lymphocyte subpopulations in contact dermatitis by sensitization to chrome and/or nickel.

Contact dermatitis is a hyperergic reaction mediated predominantly by T lymphocytes in which the target tissue is the skin. In this way and taking as a starting point that contact dermatitis is a reaction typically mediated by T lymphocytes, our aim is to study the possible existence of an unbalance between the lymphocyte subpopulations OKT-4+ and OKT-8- (T mu and T gamma) in comparison to a normal population and if, on the other hand, any of these subpopulations are involved in the increase of lymphocytes that form E active rosettes. We can see that there are no significant variations with regard to the number and function of the lymphocyte populations in individuals with contact dermatitis when we compare them to a control group. On the other hand, we consider it very important to emphasize that we have failed to detect differences in the parameters of lymphocyte populations and subpopulations studied before and after contact with the causal antigen responsible for the cutaneous condition.
