Una radiografía epistemométrica de la Revista Médica de Chile / A scientometric radiography of Revista Médica de Chile

In the context of a festschrift to commemorate the 125th anniversary of the Revista Médica de Chile, a "radiography" of the journal has been depicted using several scientometric indicators. Among the mainstream journals in the category of Medicine, General & Internal and taking into account the wide editorial coverage and the language of the publication that fulfills the need for the required social appropriation of science that the country requires, the Revista Médica de Chile portrays healthy and quite relevant. Among the articles published between 1981 and 1995, some concerning public health have reached, particularly, an impact which surpasses their mean expected citation rate

[Changes in affect in the postoperative phase: droperidol versus dipotassium chlorazepate]. / Befindlichkeitsveränderungen in der postoperativen Phase: Droperidol versus Dikaliumclorazepat.

Various studies showed an increase of anxiety and agitation after premedication with thalamonal. Subject of the present study was to specify if the psychotropic effect of the neuroleptic drug dehydrobenzperidol given during surgery is also evident during the postoperative period. Patients undergoing tympanoplastic surgery under general anaesthesia were examined by means of a psychometric analogous self judgement scale seven hours following surgical intervention. Sleep behaviour during the first postoperative night was evaluated via a question sheet. The results show that changes in condition, known from the thalamonal discussion, e.g. increase of agitation, irritability, anxious depression -- also occur during the postoperative period. During the first postoperative night, sleep was greatly disturbed. The results of a comparison group who received the benzodiazepine dipotassium clorazepate instead of dehydrobenzperidol showed a better postoperative condition and sleep behaviour.

Situación de las adolescentes centroamericanas: Tendencias y perspectivas / Situation of female Central American adolescents: Trends and prospects

Con el fin de desarrollar las "Estrategias Globales para la Infancia en el Decenio de 1990", se hizo el estudio sobre la situación de las adolescentes en los siete países de Centroamérica en torno a aspectos cruciales de la vida de las mujeres: adolescencia, educación, salud, trabajo, aspectos socioeconómicos y de políticas estatales sobre los temas anteriores. Uno de los objetivos de esta información es el de asistir a los gobiernos a mejorar la condición y calidad de vida de las niñas y mujeres jóvenes y a aumentar la participación femenina en todos niveles

[Use of structured lights in the evaluation of thoracic deformity bound with cardiac activity. Study of apical impulse using Moiré technics]. / Utilisation des lumières structurées dans l'évaluation de la déformation thoracique liée à l'activité cardiaque. Etude de l'impulsion apicale à l'aide des techniques du Moiré.

Chest deformation due to cardiac activity can be studied with the use of techniques based on Moiré principle. The shadow technique allows to obtain well contrasted fringes, whereas the technique of projected Moiré allows an easier taking of camera pictures. The fringes in this case, although less contrasted, allow to recognize level differences of the order of 0.17 mm with a network of 20 traits/mm in the present configuration of our material. The best criteria of registration have been set up after the study of 10 young subjects. In the presented case topographic measurements allowed a quantitative evaluation of the apical impulse. The telesystolic image after treatment allowed a tridimensional reconstruction of chest deformation.

Differences in psychic performance with guanfacine and clonidine in normotensive subjects.

1. Doses of clonidine 0.15 mg or guanfacine 1.0 mg, respectively, and 2 h later additional doses of clonidine 0.3 mg or guanfacine 2.0 mg, respectively, were given to 24 healthy students. 2. Blood pressure was reduced by the same amount by both drugs. 3. Plasma noradrenaline concentrations decreased with both drugs, but the reduction was significantly greater following the administration of clonidine. 4. Mental activity in the EEG was less suppressed in the guanfacine group than in the clonidine group. The differences were statistically significant. 5. Self-estimations for well-being and mood showed only small changes due to guanfacine but significant changes due to clonidine. 6. The decrease of information processing and the increase in reaction time, measured by performance in different psychometric tests, were significantly more pronounced after clonidine treatment than guanfacine. 7. A dose-response relationship could only be observed in vigilosomnograms, in the tests of self-estimation related to well-being and mood and in the decrease in plasma noradrenaline in the clonidine group. 8. It was concluded that guanfacine had a lesser CNS depressant action than clonidine, when administered in equipotent hypotensive doses.
