[The internal consistency and content validity of the Spanish version of the Asthma Autonomy Questionnaire].

The Asthma Autonomy Questionnaire (AAQ) was designed to evaluate asthmatics' desire to learn about their disease and to make decisions. The AAQ consists of 26 items distributed in two scales: Preferences in the Search for Information (PSI, 8 items) and Preferences in Decision Making (PDM, 6 general items and 12 related to 3 scenarios depicting asthma in stable phase, during mild exacerbation and during severe exacerbation). The aim of this study was to analyze the internal consistency (Cronbach's-coefficient) and content validity (factorial analysis of principal components) of the AAQ. After translation and back translation, the Spanish version of the AAQ was administered to 115 adult asthmatics of both sexes and differing levels of severity. The alpha coefficients for the two scales and 3 scenarios ranged from 0.42 (PSI) to 0.73 (stable phase scenario); only for the stable-phase scenario were values high or statistically acceptable. Factorial analysis reproduced the content of the scales only approximately, with some items proving to relate to factors that were different from the scale they originally belonged to. These results indicate that, in its current formulation, the AAQ presents important measurement problems and revision is advisable.

Löfgren's syndrome revisited: a study of 186 patients.

PURPOSE: To evaluate the clinical features, the results of noninvasive tests and biopsies, and the outcome of patients with Löfgren's syndrome. SUBJECTS AND METHODS: Patients diagnosed as having Löfgren's syndrome at a university hospital in Barcelona, Spain, from 1974 to 1996, were prospectively followed. Löfgren's syndrome was defined as the association of erythema nodosum or periarticular ankle inflammation with unilateral or bilateral hilar or right paratracheal lymphadenopathy. RESULTS: Löfgren's syndrome was diagnosed in 186 patients. The mean age was 37 +/- 11 years, and 157 (85%) were women. In 91 patients (49%), symptoms started during the spring (P < 0.0001). Erythema nodosum, periarticular ankle inflammation, or both were present at onset in 173 patients (93%). At the time of diagnosis, 161 patients (87%) had no respiratory symptoms; 151 (81%) had stage I abnormalities on chest radiograph, 29 (16%) stage II, and 6 (3%) stage 0. Five percent of patients had decreased forced vital capacity, and 15% had decreased carbon monoxide diffusing capacity. Extrathoracic involvement was infrequent. Serum angiotensin-converting enzyme levels were increased in 50% of patients. Gallium-67 scans showed hilar uptake in all the studied patients, but it yielded useful additional diagnostic information only in those with normal chest radiographs or with unilateral hilar lymphadenopathy. The diagnosis was proven with biopsy results in 63% of patients. None of the patients without histologic confirmation were subsequently found to have a diagnosis other than sarcoidosis. In the 133 patients who were followed for a mean of almost 5 years, 11 (8%) continued to have active disease, and 8 (6%) had several recurrences between 18 months and 20 years after a complete resolution. A normal serum angiotensin-converting enzyme level at diagnosis was associated with disease resolution without recurrence. CONCLUSION: Löfgren's syndrome is usually a self-limiting form of sarcoidosis. Histologic confirmation is not necessary in typical cases. In a small number of patients, the disease may remain active or recur long after its onset, although usually with mild organ dysfunction.

[Information seeking and decision making in asthmatic patients].

Patient cooperation in controlling asthma is a key element for achieving the most efficient therapy possible according to current guidelines. Cooperation requires that the patient be adequately informed about his disease and able to make certain decisions. The aim of this study was to analyze whether patients really desire information about asthma and to what point they are disposed to cooperate actively in managing their disease. Ninety-five adult asthmatics with different levels of severity of disease were studied in stable condition. All responded to the Spanish version of the questionnaire on autonomy in asthma, an instrument with a scoring range of 0 to 100 and 26 items grouped in two subscales: preferences in the search for information (PSI) and preferences in decision making (PDM). The second subscale was based on three scenarios describing stable asthma, slight exacerbation and severe exacerbation. The results obtained indicate that although patients are greatly interested in receiving information (PSI scores of 86.4 +/- 8.7) they express substantially less desire to make decisions (PDM 45 +/- 10.2) (p < 0.01). Attitudes did not change in relation to education, number of exacerbations during the last year, duration of disease or severity as assessed by the patient. Only patient age (with older patients scoring higher on PSI) and presence of severe asthma (according to consensus guidelines) increased the desire for information (but not the preference for decision making). These data indicate the need to implement educational programs about asthma, components of which promote effective desire for self-management.

A way of obtaining isoresource consumption care episodes.

The purpose of this study is to identify groups of care episodes that involve pneumologic and cardiologic problems and that exhibit homogeneous patterns of frequentation and diagnostic test consumption in an ambulatory consulting room. A 1-year prospective study of care content was done, and the episodes were retrospectively analyzed 2 years later. Data were collected in an ambulatory cardiologic and pneumologic consulting room in Spain. Nonlinear principal components analysis was applied before cluster analysis. Five typologies with a homogeneous pattern of resource consumption were obtained: three related to acute episodes of care and two to chronic ones.

Usefulness of PCR and antigen latex agglutination test with samples obtained by transthoracic needle aspiration for diagnosis of pneumococcal pneumonia.

In a large number of cases, the etiology of community-acquired pneumonia (CAP) is not established. Some cases are probably caused by Streptococcus pneumoniae. Transthoracic needle aspiration (TNA) culture has a limited sensitivity which might be improved by antigen detection or gene amplification techniques. We evaluated the capacity of a PCR assay and a latex agglutination test to detect S. pneumoniae in samples obtained by TNA from 95 patients with moderate-to-severe CAP. Latex agglutination and PCR had sensitivities of 52.2 and 91.3%, specificities of 88.7 and 83.3%, positive predictive values of 62.3 and 65.6%, and negative predictive values of 83.3 and 96.5%, respectively, when culture techniques were used as the "gold standard." When we considered expanded criteria for the diagnosis of pneumococcal pneumonia as a standard for our calculations, latex agglutination and PCR had sensitivities of 53.6 and 89.7%, specificities of 93.0 and 90.0%, positive predictive values of 78.9 and 81.3%, and negative predictive values of 80.3 and 94.7%, respectively. The additional diagnosis provided by the PCR assay compared to latex agglutination was 12.2% (95% confidence interval of the difference from 0.4 to 20. 1%). PCR was more sensitive than TNA culture, particularly in patients who had received prior antibiotic therapy (83.3 versus 33. 3%). Although PCR is a very sensitive and specific technique, it has not proved to be cost-effective in clinical practice. Conversely, latex agglutination is a fast and simple method whose results might have significant implications for initial antibiotic therapy.

Microbial etiology and bacterial resistance.

The nature of the causative organisms involved in community-acquired pneumonia has always attracted the interest of investigators. Despite multiple studies using different methodological approaches, it remains a matter of controversy because a reliable cause cannot be obtained in a significant percentage of cases, even when using more sophisticated diagnostic procedures. The recent discovery of new pathogens such as the Legionella species or Chlamydia pneumoniae, highly prevalent worldwide shows the limitations of our knowledge in that field. Recently, common respiratory pathogens such as the pneumococcus or Haemophilus influenzae, among others, showed a progressive tendency to develop resistance to penicillins and other antibiotics. Although this phenomenon has a variable impact among different countries, its growing importance is changing the classical therapeutic approach to community-acquired pneumonia.

[The 1st case in Spain of detection of occult squamous carcinoma using LIFE system].

LIFE system (lung imaging fluorescence endoscope) is a new system of detection for early lung cancer using a He-Cd laser through a conventional fiberoptic bronchoscope. This system is able to capture and processing the autofluorescence from the bronchial mucosa and to show it in a video screen in real time. In the screen the normal tissue appears in green colour and the neoplastic tissue in brown colour. The first studies performed with LIFE system show the same specificity of the conventional bronchoscopy but the sensibility is 50% higher. In this paper we present the first case of detection of a occult squamous cell carcinoma with sputum and bronchial aspiration cytology positive for carcinoma but chest X ray, CT scanner and bronchoscopy negative for lung cancer. The LIFE system was able to detect carcinoma in the carina.

Current usefulness of procaine penicillin in the treatment of pneumococcal pneumonia.

The aim of this study was to determine whether procaine penicillin could be used in the treatment of suspected pneumococcal pneumonia of mild to moderate severity in an area with a high prevalence of penicillin resistance. Forty-nine patients were treated with 1.2 x 10(6) U of i.m. procaine penicillin every 12 h. By intent-to-treat analysis, 40 of 49 patients were cured and no patient died. Streptococcus pneumoniae could be demonstrated in 17 patients; 5 of 17 isolates were resistant to penicillin (MICs 0.25-4 microg/ml). Fifteen of 17 patients were cured with procaine penicillin, one presented allergy, and one was a therapeutic failure. Mean penicillin serum levels were 2.39 +/- 1.16 microg/ml (peak) and 0.61 +/- 0.38 microg/ml (trough). The results suggest that procaine penicillin may still be useful in the empirical therapy of suspected pneumococcal pneumonia.

Long-term mechanical ventilation in amyotrophic lateral sclerosis.

BACKGROUND: Acute respiratory insufficiency (ARI) with alveolar hypoventilation or incapacitating dyspnoea but without peripheral muscle involvement can be an early manifestation of respiratory involvement in amyotrophic lateral sclerosis (ALS). Some of these patients benefit from assisted ventilation. The object of this study was to analyse the results of long-term mechanical ventilation (LTMV) in ten patients with ALS. METHODS: A retrospective analysis of intensive care unit (ICU) or ambulant patients with ALS who underwent LTMV in a conventional hospital ward was performed. Erect and supine spirometry, blood gas analysis and pulse oximetry were performed before the start and during the course of ventilation. RESULTS: Ten patients on LTMV were included. Four from the ICU were ventilated via tracheostomy, and six ambulant patients had non-invasive (nasal) ventilation. In all cases, ventilation was performed in a conventional hospital ward. The ambulant patients improved symptomatically during ventilation, confirmed by measurement of gas exchange and of SaO2 by continuous pulse oximetry. Three of the ten patients survive in long-term care--two with nasal and one with tracheostomy ventilation. CONCLUSIONS: LTMV outside ICU was possible in ten patients, seven of whom returned home. Returning home is very difficult for patients dependent on a ventilator who lack family support.

Parallel airways inhomogeneity and lung tissue mechanics in transition to constricted state in rabbits.

To investigate whether changes of tissue resistance (Rti) during methacholine (MCh)-induced constriction correspond to an intrinsic mechanism or are an artifact of increased airways inhomogeneity, rabbits were studied after exposure to air (n = 7) or 1.5 parts/million O3 (n = 6). Animals were anesthetized and mechanically ventilated. Tracheal flow and pressure (Ptr) and four alveolar capsule pressures (Pcap) were measured during 3 min after administration of an intrajugular bolus of 0.8 mg/ml MCh. By adjustment of the equation of motion [P(t) = E . V(t) + R . dV(t)/dt + P0] [where P(t), V(t), and dV(t)/dt are pressure, volume, and flow as a function of time, respectively, E is elastance, R is resistance, and P0 is end-expiratory pressure] to Ptr, lung resistance (RL) and dynamic elastance (EL) were determined breath by breath. Rti and airways resistance (Raw) were determined from Pcap in phase with rate of change of pulmonary expansion. Hysteresivity (eta) was calculated. Parallel inhomogeneity was estimated from the coefficients of variation (CV) of every Pcap at end inspiration and end expiration. Increase in CV significantly lagged Rti, RL, and eta. A linear relationship between EL and Raw was observed. Our results suggest that changes in tissue mechanics during the transition to the constricted state are not artifactual.

Transtracheal catheter acceptance and adverse events in long-term home oxygen therapy.

The acceptance of transtracheal catheters (TTC) in chronic obstructive pulmonary disease (COPD) patients with severe hypoxaemia was analysed and the adverse events associated with this system of oxygenation described. Once the TTC (Oxycat) was inserted, each patient was monitored on an outpatient basis and information about the associated adverse events was collected. In a group of 70 patients that met the inclusion criteria, only 14 (20%) accepted TTC insertion. The observed adverse events were: haemorrhage through the stoma (3); ejection of the TTC in a cough reflex (2); subcutaneous emphysema (2); mucous plugging (1); and haemoptysis (1). Removal of the TTC was necessary in 29% of the cases, and was associated with the onset of an adverse event in all cases except one. Despite the proven benefits of oxygen therapy performance and the improvement in effort tolerance, transtracheal catheter has a low level of acceptance among patients with extremely disabling diseases. The adverse events observed were frequent, but could have been corrected and in no case worsened our patients' prognosis.

An analysis of decisions by European general practitioners to admit to hospital patients with lower respiratory tract infections. The European Study Group of Community Acquired Pneumonia (ESOCAP) of the European Respiratory Society.

BACKGROUND: The purpose of this study was to identify factors on which European general practitioners (GPs) base their decisions to admit to hospital patients with lower respiratory tract infections (LRTI). METHODS: A survey was carried out from December 1993 to January 1994 to identify factors that affect GPs' decisions to admit to hospital patients with LRTI by collecting data on 2056 patients from 605 GPs in France, Germany, Italy, Spain, and the UK. RESULTS: Only 93 (4.5%) of the patients included in the study were admitted to hospital. Univariate analysis showed that age > 60 years, institutionalisation of the patient, concomitant diseases, cardiac insufficiency, asthma, a diagnosis of pneumonia, and clinical signs such as chest pain, cyanosis, tachypnoea and hypotension significantly (odds ratio (OR) > 2.0, p < 0.002) influenced the decision to admit to hospital. No influence could be shown for sex, smoking habits, history of bronchiectasis or chronic bronchitis, the presence of fever, chills, myalgia, cough or purulent sputum, and the diagnoses of acute bronchitis, influenza or exacerbation of chronic bronchitis. In the multivariate analysis only the presence of chest pain (OR 2.3, 95% confidence interval (CI) 1.5 to 3.5), cyanosis (OR 4.1, 95% CI 2.4 to 7.1), dyspnoea (OR 4.9, 95% CI 3.1 to 7.9), and hypotension (OR 2.9, 95% CI 1.6 to 5.2), as well as a diagnosis of pneumonia (OR 6.6, 95% CI 4.3 to 10) (all p < 0.00001) remained as factors that significantly affected the decision to admit to hospital. CONCLUSIONS: Clinical signs of severe infection and a diagnosis of pneumonia are the main factors that induce GPs to admit patients with LRTI to hospital in Europe.

Are the pulmonary function tests and the markers of activity helpful to establish the prognosis of sarcoidosis?

The prognosis of sarcoidosis is difficult to establish. It depends mainly on the persistence of activity over time and the degree of functional impairment of the involved organs. The aim of this study was to analyze whether the pulmonary function tests and the more commonly used markers of activity, such as serum angiotensin-converting enzyme (SACE) and gallium-67 scan, are helpful to evaluate the prognosis of sarcoidosis, besides the clinical data. Over a 14-year period (1974-1987), 209 patients were diagnosed as having sarcoidosis at the Bellvitge Hospital, a 1,000-bed teaching hospital in Barcelona, Spain. Clinical, radiological, pulmonary function tests, and activity markers (SACE and gallium-67 scan) data at diagnosis were collected and classified as variables, and a definition of disease activity was established. One hundred sixteen patients were on follow-up, had all the variables available and were included in the statistical analysis. A Cox proportional-hazard regression model identified the following variables as independently influencing the persistence of activity over time: absence of erythema nodosum [risk ratio (RR) = 2.78; 95% confidence interval (CI): 1.48-5.18], age > or = 40 years (RR = 1.67; 95% CI: 1.008-1.04), SACE level > or = mean + 2 SD U/ml (RR = 1.45; CI: 0.99-1.07), hyperglobulinemia (RR = 2.47; CI: 0.98-6.24), forced vital capacity < 80% predicted (RR = 2.17; CI: 0.97-4.85), and male sex (RR = 1.8; CI: 0.95-3.45). We conclude that the pulmonary function tests and the SACE level but not the gallium scan are helpful to identify the factors predicting persistence of activity in sarcoidosis. Therefore, we recommend to add these tests to the initial clinical evaluation of patients with sarcoidosis in order to establish the prognosis and improve the therapeutic approach.

Protected bronchoalveolar lavage in the diagnosis of ventilator-associated pneumonia.

The aim of this study was to evaluate the diagnostic efficacy of protected bronchoalveolar lavage (PBAL) in ventilator-associated pneumonia (VAP), and to determine the effect of antibiotic therapy on its microbiological and cytological results. We prospectively studied 102 episodes of suspected VAP in 93 patients. Subsequent follow-up confirmed VAP in 35 of the 102 (34%) cases. In 55 of the 102 (55%) VAP was ruled out, and the diagnosis remained undetermined in 12 of the 102 (12%) episodes. In the VAP group, 30 of the 35 (86%) PBAL (> or = 10(4) colony-forming units (cfu)-mL-1) cultures were positive. In the non-VAP group, 5 of the 55 (9%) PBAL cultures were positive. A Giemsa stain of PBAL samples was performed in 32 of the 35 cases of VAP. Intracellular organisms (ICO) were found in 24 of the 32 (75%) cases. Seven of the other eight cases without evidence of ICO were already on antibiotics. In the non-VAP group, ICO were present in only 1 out of 55 (2%) cases. The mean ICO was significantly higher in the group who had not received antibiotics when compared with those patients previously treated for less than 48 h (p < or = 0.01) and those treated for more than 48 h (p = 0.009). The sensitivity of protected bronchoalveolar lavage quantitative cultures was 87% and the specificity 91%. The sensitivity of cytological analysis for intracellular organisms was 75% and the specificity 98%. According to our results, if the patient is already on antibiotics, the direct examination of protected bronchoalveolar lavage fluid is less reliable, although still helpful.

Initial antibiotic therapy for lower respiratory tract infection in the community: a European survey.

A survey of first-line antibiotic prescription in community-acquired lower respiratory tract infection (LRTI) by general practitioners (GP) was carried out simultaneously, using the same methodology in France, Germany, Italy, Spain and the UK. Data were obtained from 2,056 patients and 605 GPs. There was no antibiotic prescription in 17% of all LRTIs and 13% of community-acquired pneumonia (CAP) in the five countries taken together; and in 32% of all LRTIs and in 23% of CAP in Germany. Of patients with acute bronchitis, exacerbation of chronic bronchitis and viral lower respiratory tract infection, 87, 92 and 71% received antibiotics, respectively. The most frequent prescriptions were penicillins in France and the UK, third-generation cephalosporin in Italy, tetracycline in Germany and macrolide in Spain. The daily dosage of aminopenicillin prescribed was: 41% <1.5 g; 49% > or = 1.5 g and <3 g; and 10% > or = 3 g. In Italy, 53% of all antibiotics were injected in all LRTIs, and 71% in CAP; in contrast, antibiotic injection was lower than 2% both in the UK and Germany, with an average of 14% in the five countries combined. We conclude that there are variations in antibiotic prescription by GPs in Western Europe; differences are likely to be multifactorial, but could, in part, be explained by differences in health systems and sources of information available to GPs.
