Prevalencia del habito de fumar en jóvenes y sus padres: asociaciones relevantes con educacion y ocupación

Rosario, with a million inhabitants, is the second major urban concentration in Argentina and serves as the commercial and industrial center for a large area. In view of the lack of information on the present prevalence of smoking in this area as for the country as a whole, a study was performed on random samples of young people and university students of medicine and economics, as well as on their parents. Information was obtained on their life smoking habits, education and occupation. The prevalence of the habit was higher: a) in men, both in the youngsters and their parents; b) in medical students than in those of the economic sciences; c) in parents with university education. The smoking habit of these subjects and parents was highly associated (p < 0.001) in the sample of young people, although no association was found between the prevalence of smoking among university students and their parents. Peer smoking was the main factor influencing the onset of cigarette smoking given by 69% of the subjects. Knowledge of specific adverse health effects of smoking was poor. Attitudes toward restrictive measures were highly associated (p < 0.001) with the non-smoker category. Based on these findings, we conclude that while there is a need for educational programs for the population in general, the university as a whole and specifically the school of medicine should implement a program to increase knowledge and awareness on this public health problem.Con el objetivo de conocer la prevalencia del hábito de fumar cigarrillos en los jóvenes, se estudiaron muestras aleatorias de varones de 18 años y de estudiantes universitarios de medicina y de economía, los que respondieron un cuestionario referido al hábito, escolaridad y ocupación propias y de sus padres, así como sus opiniones y motivaciones. La prevalencia del hábito fue mayor en los varones en ambas generaciones, en los estudiantes de medicina que en los de economía, y en los padres con nivel universitario. Se encontró asociación entre el hábito de los jóvenes de la problación general con el de sus padres (pCom o objetivo de conhecer a prevalência de hábito de fumar cigarros entre os jovens, estudaram-se amostras aleatórias de homens de 18 anos e de estudantes universitários de medicina e de economia, que responderam um questionário sobre o hábito, escolaridade e ocupação, próprios e de seus pais. A prevalência do hábito de fumar foi maior nos homens de ambas as gerações, nos estudantes de medicina, que nos de economia, e nos pais com educação universitária. Achou-se associação entre o hábito dos jovens representativos da população geral (p < 0,001), mas não entre o dos progenitores e de seus filhos universitários. Visto a participação fundamental que os universitários, em especial os médicos, deveriam ter na comunidade, surge a necessidade de programas educativos, não só nas escolas mas também nas universidades

Blood lipid associations in 18 year-old men

The association of cigarette smoking, physical activity at work, and social class with total cholesterol and with high and low density lipoprotein cholesterol were examined in a random sample of 238 males, of 18 years of age, of Rosario, Argerntina. The mean (mg/dl) total serum cholesterol of the whole sample was 174.7, the high density lipoprotein cholesterol 52.8, and the low density lipoprotein cholesterol 121.5. Black tobacco consumers, evenly distributed by social class, had higher levels of total and low density lipoprotein cholesterol. Total cholesterol was higher in the high social class, differently from what smokers' distribution by social class, would lead one to expect. While a highly negative association was found between social class and physical activity at work, there were no significant diferences in lipoprotein levels between manual and non-manual workers. It is possible that the nutritional differences by social class still prevail over the smoking habit in their influence on the lipoprotein levels in these subjects

Electrocardiographic alteration among first degree relatives with serologic evidence of Trypanosoma cruzi infection: a sibship study

To analyze whether electrocardiographic alterations (ECGA) in patients with antibodies to Trypanosoma cruzi showed a patttern of familial aggregation, a sample of 379 young adults (166 men and 213 women) distributed in sibships, were assessed for the presence of anti-T.cruzi antibodies, and subjected to a complete clinical examination and a standard resting electrocardiogram (ECG). Positive T. cruzi serology was detected in 165 individuals, 48 of them showing an abnormal ECG (overall prevalence 29 por cento). One hundred and eleven seropositive individuals were distributed in 45 sibships, each of them constituted by more than one seropositive sib, with ECGA being present in 34 out of these patients. Seropositive subjects with ECGA were detected in 27 sibships. Since the index case within each sibship is counted exactly once, affected individuals selected at random as propositi were extracted to calculate the prevalence of ECGA among first degree relatives of probands. Abnormal ECGs were recorded in 7 out of 45 sibs yielding a prevalence that did not differ from estimations registered in the general population or seropositive sibs. Data from the present sample show no familial aggregation for the occurrence of ECGA in patients with T.cruzi infection

Estudio transversal clínico y epidemiológico de la enfermedad de Chagas en una área rural del Nordeste Argentino Clinical and epidemiological transversal study on Chagas' disease in a rural area of the Argentinian Northeastern

Esta investigación tiene por objeto analizar las características epidemiológicas, clínicas, electrocardiográficas y radiológicas de una población de seropositivos y seronegativos al Trypanosoma cruzi en una área rural del Departamento San Miguel, provincia de Corrientes, Argentina. Se seleccionaron 132 pobladores (58 hombres y 74 mujeres) de todos los grupos etareos para la realización de un examen clínico y cardiovascular. Se registraron síntomas y signos compatibles con afección cardíaca, tensión arterial, electrocardiograma de 12 derivaciones y radiografía anteroposterior de tórax. En la signo-sintomatología, anomalías electrocardiográficas y en las alteraciones radiográficas detectadas, no se observaron diferencias estadísticamente significativas entre seropositivos y seronegativos. Se concluye que si bien en la población objeto de estudio la infección chagásica no se asoció a mayor prevalencia de cardiopatía, cabe destacar que los pacientes chagásicos pertenecían a un grupo etareo muy joven con un 54,0% de ellos menores de 20 años y que el 45,0% de los pacientes mayores de 41 años tenían alteraciones electrocardiográficas.<br>The main goal was to know the epidemiologic, clinical, electrocardiographic and radiologic characteristics among a population of seropositives and seronegatives to Trypanosoma cruzi in a rural area of the Departament of San Miguel, province of Corrientes, Argentina. One hundred and thirty-two patients of different ages: 2-79 years old were researched (58 males, 74 females). In order to make a thorough assessment clinical evaluation and cardiologic testing were carried out. Signs and symptoms consistent with heart disease, blood pressure, 12-lead ECG registry and chest x-ray (PA view) were registered. In signs and symptoms, abnormal ECG patterns and radiologic abnormalities, non-significant statistic difference were observed. Although we were unable to find a significant relationship between chagasic infection and a higher prevalence for heart disease, it is important to stress the fact that 54.0% of the studied population was largely composed of very young patients whose ages were less than 20 years old, and 45.0% of those older than 41 years showed ECG abnormalities

Unfavourable results in the repair of the cleft lip

Introduction: Unfavorable results in unilateral and bilateral cleft lip repair are often easy to spot but not always easy to prevent as to treat. We have tried to deal with the more common problems and explain possible causes and the best possible management options from our experience. Unilateral cleft lip repair: Unfavorable results immediately after repair involve Dehiscence and Scaring. Delayed blemishes include vermillion notching, a short lip, deficiency in the height of the lateral vermillion on the cleft side, white roll malalignment, oro-vestibular fistula, the cleft lip nose deformity, a narrow nostril and a "high-riding" nostril. We analyze the causes of these blemishes and outline our views regarding the treatment of these. Bilateral cleft lip: Immediate problems again include dehiscence as also loss of prolabium or premaxilla. Delayed unfavorable results are central vermillion deficiency, a lip that is too tight, bilateral cleft lip nose deformity, problems with the premaxilla and maxillary growth disturbances. Here again we discuss the causation of these problems and our preferred methods of treatment. Conclusion: We have detailed the significant unfavorable results after unilateral and bilateral cleft lip surgery. The methods of treatment advocated have been layer from our own experience
