[Smoking cessation in a population-based cohort study].

OBJECTIVE: To study the incidence rates and the determinants of smoking cessation in a population-based cohort. MATERIAL AND METHODS: We used data from the Cornellà Health Interview Survey Follow-up Study. Subjects who declared they were daily smokers at baseline (1994) and had complete follow-up, with information on smoking status in 2002, entered into analysis. We calculated incidence rates and the relative risks of cessation (with 95% confidence intervals) using the Cox model. RESULTS: Out of 353 daily smokers, 100 quit smoking during the follow-up period (cumulative incidence of 28.3%). The incidence rate of cessation was higher among men (42.34 per 1000 person-years) than among women (24.97 per 1000 person-years), with a relative risk of cessation of 1.69 (95% confidence interval, 1.02-2.79) for men. Age and level of education were associated with a higher relative risk of quitting in men. CONCLUSIONS: The main determinants for smoking cessation are sociodemographic (sex, age, and level of education).

Plasma cell granuloma of the hypothalamic region.

Two patients suffering from diabetes insipidus, with additional symptoms of impaired vision and signs of panhypopituitarism and increased intracranial pressure, showed a normal sella tursica in the X-ray examination of the skull but large, dense space-occupying lesions in the hypothalamus on CT scans of the brain. NMR performed in one patient disclosed suprasellar growth of a hypothalamic lesion. Proliferation of lymphoplasmocytes and mature plasma cells was seen by light microscopic and electromicroscopical examination of biopsy samples in both cases; histiocytes and multinucleated giant cells were absent; tuberculosis, syphilis and sarcoidosis were ruled out by appropriate tests. Plasma cells exhibited polyclonal immunoglobulin expression as revealed by immunocytochemistry using the PAP method. Taken together these features are typical of plasma cell granuloma. Transitory remission after radiotherapy was obtained in one patient.

Direct intracavernous obliteration of high-flow carotid-cavernous fistulas.

Four cases of high-flow carotid-cavernous sinus fistula (CCF), three of them posttraumatic and one spontaneous, have been treated by a direct surgical approach to the cavernous sinus. The CCF's were obliterated by the introduction into the cavernous sinus of muscle fragments and/or fibrin sealant. In the three cases with a preoperatively patent internal carotid artery (ICA), the CCF was occluded and the ICA flow preserved. One of these also had a posttraumatic false aneurysm that enclosed the two avulsed ends of a transected intracavernous ICA. This was treated by cervical ICA ligation following resolution of the CCF. A fourth patient, who had previously undergone an unsuccessful ICA trapping procedure elsewhere, also obtained a good result. The case histories and the surgical technique are presented. Direct intracavernous obliteration with muscle fragments and fibrin sealant fulfills the criteria for treatment of high-flow CCF's: occlusion of the arteriovenous fistula and preservation of the ICA circulation. While this surgical technique is a therapeutic option in some cases, it appears to have precise indications in others.
