[Cor pulmonale-PHT secondary to crest syndrome. Treatment with slow continuous ultrafiltration]. / Cor pulmonale hipertensión pulmonar secundaria a síndrome crest. Tratamiento con ultrafiltración lenta continua.

Pulmonary hypertension is a severe disease with complex treatment based on general measurements, anticoagulation and use of specific vasodilator drugs. Right heart failure initiated in final stages of the disease is treated with diuretics. We present the case of slow continuous ultrafilitration as treatment in right heart failure secondary to pulmonary hypertension associated to collagen disease refractory to diuretic treatment.

[Smoking prevention intervention among secondary school students in the Spanish province of Malaga]. / Intervención sobre tabaquismo en estudiantes de enseñanza secundaria de la provincia de Málaga.

OBJECTIVE: To assess the prevalence of smoking among 13- to 18-year-old students, analyze smoking-related factors in this population, and design an intervention program to reduce smoking. POPULATION AND METHODS: A 6-month smoking prevention intervention was designed for students at a public secondary school in the Spanish province of Malaga. The objective of the intervention was to inform students of the gravity of smoking and its deleterious effects on health. The efficacy of the intervention was subsequently assessed. RESULTS: Of the 337 students who completed the questionnaire, 27% declared they were smokers. Smoking prevalence was significantly higher among girls (36.1%) than boys (18.1%) (P<.001) and progressively increased with age. Initiation occurred at 13 to 14 years of age. The most common reason for starting was to try something new (52.2% of students). The greatest risk factor in the family environment was having a smoking sibling. After the program, 78% of smokers admitted that the intervention had not affected their smoking but had made them more aware of its detrimental effects, and 66.8% planned to quit in the future. CONCLUSIONS: The study shows the high prevalence of smoking among adolescents, particularly among girls. It also shows that health education increases understanding of the problems related to smoking, causing changes of attitude with regard to whether they will smoke in the future.

[Cancer of the lung in patients with HIV infection]. / Cáncer de pulmón en pacientes con infección por VIH.

OBJECTIVE: To know the characteristics of lung cancer among patients with HIV-1 infection. METHOD: The clinical records of patients infected with HIV-1 and lung cancer diagnosed at our institution from January 1991 to April 1995 were reviewed. The epidemiological, clinical, histological and evolutive factors were studied. RESULTS: A total of 1,258 patients were diagnosed of HIV-1 infection during that period of time. Seven patients out of those 1,258 had also a lung cancer. Six were males. All of them were smokers and had severe immunodepression. In four cases the histological diagnosis was epidermoid carcinoma, in two adenocarcinoma, and in one case undifferentiated large cell carcinoma. Five patients were on advanced stages at diagnosis, and lung cancer was the direct cause of death. CONCLUSION: The frequency of lung cancer among our patients with HIV-1 infection was 5.5 per thousand, with predominance of epidermoid carcinoma.
