[Etiological and prognostic factors in the late onset epilepsy].

The etiological and prognostic factors of epilepsy starting in adulthood have been studied globally and especially in the case of that group of patients whose epilepsy begins after the age of 60. However, a specific study of patients whose epilepsy has begun after the age of 40 has not been made so far. In this report the above-mentioned factors are analysed in patients who were examined consecutively in our center between May 1986 and December 1990, all of whom had had their first epileptic attack after the age of 40. During this period 85 patients [55 (74.07%) women: 30 (35.3%) men: average age: 65.41 +/- 13.23] fit in to this category. The starting age was 61.6 +/- 13.5. The most frequent causes of the epileptic attacks were cerebrovascular accident (41%) and alcoholism (16%). In 1% of cases, the cause of the attacks could not be identified. Antecedents such as chronic alcoholism and tobacco addiction, were more frequent among the men (30.9% against 3.3% p: 0.014 and 49.1% against 0% p: 0.0000, respectively). The most frequent etiology in the age group comprised of patients between 40 and 50 years of age was alcohol and drug consumption. In the group of patients aged between 70 and 80, the most frequent finding in computerised cranial tomography was encephalic infarction. The factor linked to an unsatisfactory development of the epileptic process was nonobservance of therapeutical recommendations registered clinically as well as by means of the calculation of plasmatic levels of antiepileptic medicaments (p: 0.0000). Consumption of alcohol was the factor linked in a significant manner to the nonobservance of therapeutical recommendations (p: 0.0128).

[The prevalence rate for cardiovascular diseases antecedents in patients with migraine].

Throughout the many studies carried out on patients suffering from migraine, we find that a series of diseases or abnormalities with cardiovascular etiologies may be associated with the risk of migraine. In some studies published so far there is a greater prevalence of distinct cardiovascular diseases among those patients suffering from migraine. The shortage of case-control studies which might otherwise definitely establish a relationship between migraine and other cardiovascular diseases leads us to cautiously interpret the meaning of these associations. We studied family and personal history of cardiovascular disease in a group of patients with migraine, and we carried out a case-control study to try to establish the greatest risk of suffering from these diseases by our patients. We found that family antecedents of migraine with the next of kin was a risk factor for getting migraine and that Raynaud's disease was associated with a greater risk of suffering with this pathology.

[Clinical, epidemiologic, and microbiologic study of urinary infection in patients with renal transplant at a specialized center in Argentina].

Sixty-four patients were evaluated for urinary tract infection (UTI) during the first six months after renal transplantation. Eighty per cent received the allograft from a living, related donor and 37% were female. The median age was 33.8 years. All the patients received cefazolin as perioperative antibiotic prophylaxis. No prophylaxis was given during the bladder catheterization period, which had a median duration of 5.9 days. Nineteen per cent developed predisposing urological factors (PUF). The incidence of UTI was 41% and 15% of all these patients developed bacteremia from this source. UTI was observed in 50% of the patients without PUF between the 5th and 12th days post-transplantation, and these cases had been detected by the control urine culture performed when the bladder catheter was withdrawn. This group of patients accounted for 14% of all the patients. Recurrence was present in 42% of the patients with UTI (19% had reinfection, 4% relapse and 19% both). They were more frequent in patients with PUF than in the patients without; 78% vs. 24%, respectively (p < 0.05). The overall UTI incidence was also higher; 75% vs. 33%, respectively (p < 0.05). The same was observed for the median number of episodes (3 vs. 1). The organisms most frequently isolated were E. faecalis (21%). E. cloacae (17%), and E. coli (17%). Species prevalence differs from that of other reports, probably due to the different institutional antibiotic management. Since half of the UTI episodes suffered by patients without PUF were associated to bladder catheterization, there is a need to institute antibiotic prophylaxis in our center.

[Non-invasive diagnosis of rejection in heart transplant: usefulness of Doppler echocardiography].

Cardiac transplantation is a valid therapeutic option for advanced chronic heart failure, with a one year survival of 60-80%. Although the introduction of cyclosporine has markedly improved survival in heart transplant recipients, early detection of cardiac allograft rejection remains the major problem to be solved. At present, the diagnosis of cardiac rejection has been based on the results of endomyocardial biopsy, which remains actually as the gold standard for rejection surveillance. However, ideally the detection of cardiac rejection should be noninvasive to allow frequent follow-up of the patients. Several attempts have been made to find a noninvasive alternative to replace endomyocardial biopsy, doppler-echocardiography being the most promising technique. A review of current noninvasive methods for graft rejection detection will be discussed emphasising the importance of doppler-echocardiography.

[Outpatient ENT surgery in a district hospital].

Our experience in out-patient surgery from October 1994 to July 1996 is reported. Patients were selected using anesthesiology criteria (anesthetic risk I or II, psychosocial criteria, operation time less that 1 h 30 min, age > 6 years). One hundred seventy-eight patients underwent surgery: 61 direct suspension laryngoscopy, 50 adenoidectomy, 48 septoplasty, 10 functional endoscopic sinus surgery, 8 myringotomy, and 1 nasal decortication. Fourteen patients (7.86%) required hospital admission. No patients required ENT care in the first 24 hours after release from the Ambulatory Surgery Unit.
