[Descriptive study of a pneumonia episode due to Legionella].

BACKGROUND: Legionella is a gram negative aerobic bacillus. A total of 42 species with 64 serogroups have been described, Legionella pneumophila serogroup 1 being the one that causes the disease most frequently. OBJECTIVE: Describe an outbreak of legionellosis with some characteristics different from those communicated previously. MATERIAL AND METHODS: Descriptive study of the epidemiological and clinical characteristics of the patients affected by an outbreak of pneumonia due to Legionella pneumophila serogroup 1, that occurred in Vigo in September and October, 2000, seen in the Hospital Xeral-Cies. RESULTS: A total of 33 patients, with a mean age of 61 years, were diagnosed. Fifty-nine percent had underlying diseases. The most frequent symptoms were fever, cough, dyspnea, diarrhea and awareness level alterations. Elevation of creatinphosphokinase in 79% and hyponatremia in 12%. The X-ray pattern observed most frequently was unilateral alveolar with predominant involvement of inferior lobes. A total of 77% received treatment with beta lactamics and macrolides, 13% beta lactamics and quinolones and 7% quinolones. Clinical and gasometric improvement were observed at a mean of 5 and 7 days, respectively. X-ray abnormalities improved in 62% in the first week. Eighteen percent had multiorgan failure and four patients died. In the analysis of the variables considered to have poor prognosis, only multiorgan failure demonstrated a significant association with mortality. DISCUSSION: The characteristics of the patients affected by an episode of legionellosis in our health care area were similar to those described in other outbreaks, except for the rapid resolution of the pulmonary infiltrates and low presence of hyponatremia. Multiorgan failure was the only factor associated with poor prognosis.

[Clinical usefulness and cost-effectiveness of transbronchial needle aspiration for the diagnosis of mediastinal adenopathy].

Transbronchial needle aspiration (TBNA) of mediastinal or hilar enlarged lymph nodes is a useful and safe technique. Nevertheless, its use has not become widespread, and the necessity of a specific training to obtain good results has been reported. In order to evaluate the clinical usefulness and cost-effectiveness of TBNA in inexperienced brochoscopists in this technique, a prospective study was conducted of this technique used in all patients with a chest CT with paratracheobronchial lymph nodes larger than 10 mm who had a fiberbronchoscopy ordered. TBNA was performed in 66 lymph node staging in 59 patients. In 76% of cases adequate specimens were obtaned, and a cytohistologic diagnosis was established in 59%. In 44% of patients, TBNA avoided other more invasive diagnostic procedures. Had TBNA not been performed, cost was estimated to have been at least five times higher. We conclude that TBNA could be a useful cost-effective technique in inexperienced teams.

[Pulmonary inflammatory pseudotumor: report of 2 cases and review of the literature].

Inflammatory pseudotumor (IP) of the lung is a rare pathological entity and its ethiopatology is unknown. It is considered to be a benign lesion with an array of histologic appearances. Although, the pulmonary affection is the most frequent, any other organ can be involved. We report two cases de pulmonary IP, one of them endobronchial, and discuss the clinical and anatomopathological features and review the pertinent literature.

[Adenosine deaminase activity in the pleural effusion. A study of 64 cases].

Clinical and analytic data of 64 patients with firm etiologic diagnosis of pleural effusion with adenosine deaminase (ADA) present, were analyzed retrospectively. The patients had entered our hospital over a 40-month period. ADA activity in pleural fluid was analyzed by the Blake and Berman kinetic method. Mean ADA activity of the total sample was 32 U/l (SD:23.9). In patients with tuberculous pleural effusion ADA activity was higher than in the remaining patients (47.7, SD:21.4, versus 15.5 SD: 13.2; p < 0.0001). In the group of patients with tuberculous pleuritis diagnosed by pleural biopsy (22 cases) the presence of necrotizing granulomas was associated with slightly higher ADA activity although the difference was not statistically significant (49.2 SD 10.1 versus 41.3 SD 8.9; p = 0.07). Among only patients with tuberculous pleuritis or neoplasia with lymphocytic exudate, a cut off point greater than 23 U for ADA predicted a diagnosis of tuberculous pleuritis with a sensitivity of 0.96, specificity of 1, positive predictive value of 1, negative predictive value of 0.94, and a confidence limit of 0.97. In conclusion, ADA activity greater than 23 U determined by the kinetic method in pleural fluid with signs of lymphocytic exudate is strongly suggestive of pleural tuberculosis based on our sample of patients with pleural effusion.

[The use of oxygen as therapy in a general hospital].

A prospective study of the therapeutic use of oxygen in a general hospital was carried out. 120 patients who received oxygen during the first 24 hours of their admission were included. Oxygen was prescribed continually for 113 patients (94%). This was administered with a Venturi mask in 116 patients (97%). Medium FiO2 prescribed initially was of 0.29 (SD = 0.04). Basal arterial blood gas measurement was performed on 101 patients (84%). PaO2 was equal to or lower than 60 mmHg in 69 (68%). Arterial blood gas measurement control was carried out in 51 patients (42.5%). Of the patients with basal PaO2 lower or equal to 60 mmHg, 44 (64%) were submitted to posterior control measurement. 32 of the latter group showed PaO2 higher than 60 mmHg. We observed important deficiencies: increased prescription in patients with PaO2 greater than 60 mmHg; the frequent noncontrol of arterial blood gas measurement; the lack of correction of FiO2 when the initial application of O2 did not increase the PaO2 higher than 60 mmHg.
