[Tuberculosis in Santiago de Compostela from 1999 to 2002. An epidemiological study].

OBJECTIVE: The purpose of this study was to determine the epidemiological characteristics of tuberculosis (TB) in the Public Health System District of Santiago de Compostela (population : 386125) from 1999 to 2002. METHODS: Inclusion criteria were: 1). microbiological and/or pathological diagnosis of TB in any specimen, and 2). patient younger 35 years old with recent medical history of TB. Mantoux test positive, and pleural effusion with linfocitosis and adenosine deaminase >47 IU/ml. RESULTS: 946 patients were included (568 men and 378 women), with ages ranging from 2 months to 96 years. The incidence of TB was 60.9/100000 in 1999, 67.6/100000 in 2000, 61.9/100000 in 2001 and 54.6/100000 in 2002. The incidence rate of tuberculous meningitis was 1.03/100000 in 1999 and 2000, 0.77/100000 in 2001 and 0.51/100000 in 2002. The percentage of cases associated with HIV was 3.4% in 1999, 1.9% in 2000, 2.4% in 2001 and 2002. We found an increase in the rate of males over 55 years of age; with incidence per 100000 inhabitants of 122.4 in 1999, 142.8 in 2000, 115 in 2001 and 119 in 2002, whereas in females the incidence was 40.6 in 1999, 60.9 in 2000, 54.1 in 2001 and 39.1 in 2002. CONCLUSIONS: In last four years the incidence of tuberculosis has decreased but remains high in males over 55 years old.

[Non-invasive ventilation in chronic obstructive pulmonary disease patients with acute respiratory hypercapnic failure in a conventional hospital ward].

OBJECTIVE: To analyze chronic obstructive lung disease (COPD) subjects in acute hypercapnic failure who were treated with non-invasive mechanical ventilation in a general respiratory ward. METHODS: This was a two-year prospective study of 35 patients with acute exacerbation of COPD and mean FEV1/FVC relation in stable condition of 55.3 +/- 14.8% of predicted that were treated with positive pressure respiration using a facemask in a general respiratory ward. 17 (48.5%) receive long-term oxygen therapy. Analysis was made of blood gases, before and after treatment of non-invasive ventilation, complications, and failure during treatment. RESULTS: A significant improvement in blood gases was observed 24 hours after non-invasive ventilation treatment. The mean hospital stay was of 15.0 +/- 9.1 days and failures were registered in 3 cases (8.5%). Facial scares were the most common complication (13 patients) but it was possible to continue treatment. CONCLUSIONS: Non-invasive ventilation is a viable treatment for patients with chronic obstructive lung disease and acute hypercapnic failure being treated in a general respiratory ward.

[Respiratory symptoms and lung function in a geriatric population of a Galician rural community: a pilot study].

INTRODUCTION: Respiratory diseases are a frequent cause of health demands and have a large impact on morbidity and mortality of the Galician population, especially among the older one. Recent work shows that the diagnosis and treatment of these diseases is not optimal. This increases the utilisation of health care resources. MATERIAL AND METHODS: We studied 28 patients of the municipality of Val del Dubra (Northwest Spain) aged between 65 and 74 years. We performed a spirometric exploration and carried out a questionnaire interview on respiratory symptoms, life style, and occupational and health-related antecedents. RESULTS: Among men, 54% of were or are smokers. None of the women ever smoked. Respiratory symptoms were more frequent among women than among men (80% versus 54%). In the spirometric study, the largest volumes and flux are observed among non-smoking males who do not report dyspnea. DISCUSSION: Respiratory symptoms are frequent in the rural population aged between 65 and 74 years. Tobacco consumption is similar to other Spanish communities, but different from that seen in other countries. Male gender, non-smoking status and absence of respiratory symptoms are associated with higher spirometric figures.

[Pulmonary diffusion of carbon monoxide in patients with mitral stenosis].

OBJECTIVE: The aim of our work has been the study of CO diffusion capacity in mitral valve stenosis patients. METHOD: We have studied 15 control subjects and 15 patients with mitral valve stenosis. We performed spirometry study and CO pulmonary diffusion tests (DLCO) by single breath method to determine two components: pulmonary capillary blood volume (Vc) and membrane diffusion factor (Dm). In addition, in mitral valve stenosis patients we performed a ecocardiography-doppler study. RESULTS: The mitral valve stenosis group had higher values of DLCO and Vc and a lower ratio of Dm/Vc than the control group. There is a negative correlation between Vc and the mitral valve area (r = -0.63; p = 0.037). We do not find any another correlation between the rest of ecocardiography doppler parameters and lung function test variables that we have measured. We have not found any differences between both groups in Dm. CONCLUSIONS: Mitral valve stenosis patients present a increase of CO pulmonary diffusion capacity and pulmonary capillary blood volume without changes in membrane diffusion factor.

[Epidemiologic study on tuberculosis in the health area of Santiago de Compostela in 1995, 1996, 1997, and 1998].

BACKGROUND: We report the epidemiological characteristics of tuberculosis(TB) in the area of Santiago de Compostela (Spain) between 1995 and 1998. METHODS: Inclusion criteria were: 1) microbiological and/or pathological diagnosis of TB in any specimen, and 2) consistent recent medical history of TB with reading > 5 mm to 2 TU PPD tuberculin test 48-72 hours after injection, and adenosine deaminase in pleural effusion > 47 IU/ml. RESULTS: 1,150 patients were included (685 males and 465 females), with mean of age (X) 38.9 years (19.8 SD), range 3 months-88 years. The number of cases was 307 during 1995 and 1996, 302 in 1997 and 213 in 1998. The incidence rate (per 100,000 habitants) was 78.3 in 1995 and 1996, 79.8 in 1997 and 61.9 in 1998. The incidence rate of meningitis was 1.8 in 1995, 1.3 in 1996, 1.05 in 1997 and 0.8 in 1998, with no meningitis in children under 5 years. Cases in association with VIH were 4.2% in 1995, 3.3 in 1996, 5.4 in 1997 and 3.2 in 1998. More of the 50% of cases in both genders were between 15 and 40 years old with another peak over 65 years. The ratio men/woman was 1.8 in 1995 and 1.4 in 1996, 1997 and 1998. CONCLUSIONS: The incidence of tuberculosis has diminished during the last year, but is too early to know the real tendency.

[Sleep apnea syndrome and cardiovascular diseases].

The sleep apnea syndrome is a common disease, recognised as a public health problem. Cardiovascular disease is the most frequent cause of morbidity and mortality in these patients, however the underlying mechanisms of this association have not been clearly established. In sleep apnea syndrome different phenomena can be produced which may explain the appearance of cardiovascular problems, such a progressive hypoxia in relationship with the apnea, the increases of intrathoracic pressure cause by the efforts of ventilation system against close upper airway and the modifications of the autonomic nervous system associated with the arousals. In addition, the hypoxia episodes and reoxygenation, which appear in the sleep apnea syndrome, may play a important role in the alteration of the balance between vasoconstriction and vasodilatation substances affecting the vascular homeostasis and conditioning endothelial dysfunction. On the other hand, the increasing of platelets aggregation and the decreased of fibrinolisis in this group of patients may cause vascular diseases.

[An epidemiological study of tuberculosis in the health area of Santiago de Compostela during the years 1989, 1990 and 1991].

In order to assess the incidence of tuberculous disease in our health area, we reviewed the clinical records of patients from the three hospitals of the area under study during the years 1989, 1990 and 1991, who had positive bacilloscopy, positive Lowenstein's culture in any specimen and/or compatible anatomopathologic report. After excluding 26 patients because they belonged to other health areas, 885 patients remained in the study, out of which 251 (64% men and 36% women) were from the year 1989, 270 (64% men and 36% women) from the year 1990 and 364 (62% men and 38% women) from the year 1991. The mean age was 38.4 (SD 20.5). Fifty-one percent of the patients were between 20 and 35 years old. The rate of new cases was 65.87 per 100.000 population in 1989, 71.05 in 1990 and 95.53 in 1991. Seventy-four cases were HIV-positive (8%). Tuberculous meningitis was present in 12 patients. The highest mortality was 1.79 per 100.000 population in 1990. We conclude that tuberculosis presents a medium-high incidence in our health area.

[Metoprolol in the treatment of essential hypertension (author's transl)].

The cardioselective betablocking agent metoprolol was used to treat 21 outpatients with essential arterial hypertension graded 1 and 2 of the OMS scale. The treatment was given orally for a mean duration of nine weeks at doses of 100 mg/day for two weeks and 200 mg/day for the remaining time. The treatment caused a significant reduction of systolic and diastolic arterial pressure (p less than 0.001), both in the erect and the lying down position. The heart rate was also significantly reduced both in the lying down (p less than 0.01) and the erect (p less than 0.05) positions. Metoprolol was shown to be effective and well tolerated as an antihypertensive agent; the treatment had to be interrupted in a single case because of dizziness, tiredness and dullness.
