Background and Objective: N-terminal pro-brain natriuretic peptide (NT-proBNP) is a useful predictor of cardiovascular events in patients without clinical evidence of cardiovascular disease. It is unknown if the cardiovascular risk factors control can modify these levels. We studied if atorvastatin treatment decrease NT-proBNP levels in hypercholesterolemic subjects, with and without hypertension., Patients and Method: It was an open, prospective study in 39 patients with hypercholesterolemia without clinical evidence of cardiovascular disease. 15 (38.5%) had hypertension. Blood samples were collected initially and 12 and 24 weeks after beginning treatment with 20 mg of atorvastatin., Results: The median age was 54 years, and 41% were males. NT-proBNP (pg/ml) values were: 193 (294) at baseline; 141 (211) (p < 0.05) after 12 weeks therapy, and 89 (130) (p < 0.01) at 24 weeks. In hypertensive patients value changed from: 275 (388) at baseline, 196 (290) (p < 0.05) and 112 (124) (p < 0.001) after 12 and 24 weeks treatment. And the levels in normotensives patients were: 137 (198) at baseline, 103 (129) (p = NS), and 74 (135) (p < 0.001) at 12 and 24 weeks after treatment with atorvastatin. We didn't find any correlations between the percentage decrease in NT-proBNP levels, and change of total cholesterol, systolic blood pressure, C reactive protein, or nitrites/nitrates blood levels, at 12, and 24 weeks compared to baseline levels., Conclusions: In middle-aged hypercholesterolemic patients, without evidence of cardiovascular disease, atorvastatin therapy decrease NT-proBNP blood levels, in both hypertensive and normotensives subjects.

Background: Invasive fungal infections (IFI) are one of the most important causes of mortality in liver transplant (LT) recipients. The aim of this study was to describe the characteristics of IFI in the LT program of our institution with an special emphasis in the differences between Candida infections (CI) and that caused by other fungi (NCI)., Patients and Methods: Retrospective analysis of the hospital charts of 21 patients who underwent a LT from February 1987 to December 1995. The diagnosis of IFI required the histological evidence of tissue invasion or a positive culture in a tissue sample or in an usually sterile fluid. Esophageal candidiasis was not considered as IFI. Antifungal prophylaxis was performed either with nystatin or fluconazole., Results: Twenty-one of 356 patients (6%) developed a total of 23 episodes of IFI. Pathogens were Candida spp. (n = 10), Aspergillus (n = 8), Zygomicetes (n = 4) and Cryptococcus (n = 1). Fifty-seven percent of the episodes of IFI (80% of those caused by Candida and 38% of those produced by other fungi; p < 0.05) developed in the first 3 months after transplantation and only 5 episodes appeared after the sixth month. The diagnosis of IFI was done at autopsy in 6 patients (29%). Overall, NCI (13 episodes) predominated over CI (10 episodes), being the later the cause of the 54% of the episodes in the first 178 recipients but only the 30% in the last 178 patients (p = 0.09). No differences were found in the distribution of the risk factors amongst those patients with CI or NCI. Seventeen of the 21 patients (71%) died and 15 of these deaths (72%) were attributable to fungi; 15 patients who died either did not receive amphotericin (n = 6) or received a cumulative dose lower than 500 mg. Six patients received a cumulative dose of more than 1.5 g (mean, 3.2 g) and four of them were cured. Mortality in the nonfungal infection group was 26% (p < 0.001)., Conclusions: IFI was a rare but severe complication in our LT recipients. The relative frequency of CI was progressively decreasing during the study period, being NCI the predominant infections. Amphotericin therapy was effective only when a high cumulative dose could be administered.

The paradoxical embolism or the crossing of an embolism through a permeable foramen ovale is considered to be a rare mechanism of cerebral embolism although its real frequency is unknown. Reports demonstrating the embolism during its crossing through cardiac cavities are scarce. Two cases of moving paradoxical embolism are presented. In the first, an infarction of the superior branch of the left middle cerebral artery was produced during the course of deep vein thrombosis and pulmonary thromboembolism with transesophageal echocardiography demonstrating the crossing of the embolism through the foramen ovale. Surgery performed 12 days later did not discover the auricular thrombus. In the second case, a mass was discovered in the right auricle with a permeable foramen ovale during the course of a left middle cerebral artery infarction and a large auricular thrombus was demonstrated in surgery. The diagnostic usefulness of early transsesophageal echocardiography in the diagnosis of moving paradoxal embolism is discussed.

Background: Stroke is the cardiovascular disease which causes the greatest number of deaths in Galicia, mortality, particularly in women, being higher than in the rest of Spain. The aim of this study was to investigate the risk factors of stroke and its importance in Galicia., Methods: A hospitalary study of cases and controls was performed including 76 patients with stroke and 76 controls individually paired for age, sex, population habitat and date of admission with anamnesis, weight, height and blood pressure, analysis and electrocardiogram being carried out in all., Results: An association was found between the disease and family history of stroke (odds ratio = 3.6, confidence interval 95% = 1.2-13.3), personal history of stroke (17.9; 4.0-79.1), personal history of atrial fibrillation (15.0; 3.3-68.3), high blood pressure (4.5; 1.9-11.6) and ingestion of alcohol greater than or equal to 80 g/day in comparison with abstemious patients adjusted for the effect of high blood pressure (2.5; 1.1-5.7). An association was also observed with serum cholesterol levels greater than or equal to 250 mg/dl (6.46 mmol/l) (3.3; 1.2-8.8, in comparison with cholesterol less than 200 mg/dl). No association was found with the cigarette smoking (1.2; 0.7-2.3)., Conclusions: The results observed for high blood pressure and the ingestion of alcohol regardless of the same are of importance in primary prevention due to being modifiable risk factors. The association with family history of stroke and auricular fibrillation reinforce the needs for primary prevention measures in these subpopulations while having had a stroke or a transitory ischemic attack is the characteristic with the most risk reinforcing the need for secondary prevention measures which have found to be effective. The controls presented abnormally low cholesterol levels that do not reflect those of the population from which they originate, thus existing the possibility that the association observed is spurious.

Background: The coexistence of syphilis and infection by the human immunodeficiency virus (HIV) appears to modify the natural history of both diseases. The aim of this study was to know the prevalence of syphilis in a population of patients with HIV infection, the possible association with certain risk practices and the validity of the reaginic test in such patients., Methods: Three hundred sixty-seven patients with HIV infection who went for the first time to a monographic clinic of a university hospital were studied. Syphilis serology was carried out: rapid plasma reaginic (RPR) and hemagglutination (MHA-TP) tests., Results: Out of all the patients 26 (7.1%) had positive MHA-TP. The proportion of homosexuals was greater among those who had a positive treponemic test (69%) than among those who were negative (6.4%; odds ratio [OR] = 32.6; confidence interval 95%: 16.2-65.4). The positivity of MHA-TP was more frequent among those presenting criteria of the acquired immunodeficiency syndrome (AIDS) at the diagnosis (18% versus 5.6%; OR = 3.6 [1,5-8,9]). Seventy-four false positive reactions were observed with the RPR (20%) corresponding almost exclusively (96%) to intravenous drug users who presented false positivity in 25% of the cases., Conclusions: The prevalence of syphilis detected by treponemic serology among subjects with infection by the human immunodeficiency virus is related with homosexuality as the principal practice of risk. One quarter of the intravenous drug users with infection by the human immunodeficiency virus presented false positive results to the reaginic test thus leading to the recommendation that therapeutic measures should not be initiated without confirmation with a treponemic test.

Background: Disseminated infection by Mycobacterium avium-intracellulare is almost exclusively produced in individuals with HIV infection. The incidence of this infection in Spain is unknown., Methods: The clinical and microbiologic registries of 30 patients with AIDS and disseminated infection by Mycobacterium avium are reviewed., Methods: Twenty-three percent of the patients with AIDS had, at some time in their evolution, disseminated infection by M. avium. The clinical picture included prolonged fever, digestive symptoms, weight loss and appearance of lymph node enlargement. This infection appeared in patients with severe alteration of cellular immunity (mean CD4 lymphocytes: 0.19 x 10(9)/l). Although medium term prognosis was bad the causes of death of the patients were other opportunistic diseases related with the immunodeficiency., Conclusions: Infection by Mycobacterium avium is frequent among the population of individuals with HIV infection. With the appearance of prolonged fever in a patient with HIV infection and CD4 lymphocyte count lower than 0.2 x 10(9)/1 appropriate microbiologic studies including blood cultures for mycobacteria should be initiated.

Background: To evaluate the efficacy of flurbiprofen (nonsteroidal anti-inflammatory drug) in the treatment of biliary colic pain as compared with the drugs commonly used (analgesics and/or spasmolytics)., Methods: Eighty-four patients aged between 21 and 86 affected by intense pain of simple hepatic colic participated in the study. Following a single intramuscular dose of 150 mg of flurbiprofen (FRI, n = 30), 20 mg of N-hyoscine butylbromide (HBB, n = 25) or 30 mg of pentazocine (PTZ, n = 29) the patients were observed during the 6 hours after administration., Results: The evolution of the pain was significantly better in the patients treated with FRI with differences being detected between the three drugs after 30 minutes of administration. A greater number of adverse reactions were seen among the patients who received PTZ with the differences being statistically significant with the other 2 treatments (p less than 0.02)., Conclusions: Intramuscular flurbiprofen was more effective and generally better tolerated than pentozocine and hyoscine butylbromide.

The mortality rate and clinical, analytical, radiographic and pathologic data from 31 patients with acute appendicitis over 60 years of age are compared to those from 100 patients under 60. The elderly group showed a greater delay in medical consulting, a more diffuse abdominal pain and a greater incidence of perforated and gangrenous appendicitis. This last fact could be related not only to the consulting delay, but also to the own characteristics of the aged appendix. There were no significant differences between both groups regarding analytical results and radiographic findings. Mortality rate was 13 percent in the elderly, while it was null in the younger series.

One hundred cases of acute abdomen in patients over 70 years of age were studied. Mechanical occlusion was the most common cause among these patients, as opposed to acute appendicitis, which is the primary cause of the same condition among young people and adults. Irreducible hernias and visceral neoplasias were the most frequent etiologies among cases of mechanical occlusion. Cholecystitis took second place in our series. Visceral peforations were more often due to localized infections or visceral neoplasias than to gastric or duodenal ulcers. Overall mortality among these patients was 29 percent. Patients with visceral perforations due to localized infections or visceral neoplasias and all of the patients with vascular diseases had a negative prognosis.
