[Analysis and detection of fibres in the pulmonary tissue].

Microscopic techniques for the analysis of fibres in pulmonary tissue and bronchovesicular washing have provided information of great interest for a better understanding of diseases related to the inhalation of asbestos. These tests serve to help in establishing an individual estimation of previous exposure to asbestos. A mineralogical analysis of the concentration of intra-pulmonary fibres can be needed on some special occasions, for example when the data obtained from the occupational history are of scarce relevance or inconclusive. For these reasons, this type of study is increasingly used in clinical work and in resolving medico-legal problems, but the complexity of some of them makes the creation of reference laboratories useful as they make methodological homogenisation possible and facilitate the comparison of results. Plueropulmonary diseases related to inhaling asbestos are considered to be of occupational type and are therefore subject to a series of legal requisites for their recognition and possible compensation. A history of exposure with a suitable latency period, together with a compatible clinical-radiological picture, can be sufficient for the diagnosis but, in certain situations, such as when the exposure data are not precise, the analysis and detection of asbestos fibres in respiratory samples or from the pulmonary tissue can be clarifying.

[Tuberculosis as an occupational disease].

Health workers are exposed to numerous infectious diseases from which the patients they attend are suffering and that have been recognised as occupational infectious diseases. Those most frequently reported are acquired by the haematogenous path, especially hepatitis due to virus B. Numerous infectious diseases are transmitted through airways and until the coming of acute severe respiratory syndrome caused by a coronavirus, tuberculosis was one of the most dreaded. In this paper we analyse the reasons why tuberculosis is considered to be an occupational disease in health personnel; which activities entail most risk and the measures that should be adopted to reduce nosocomial transmission.

[Diagnosis and treatment of obstructive sleep apnea-hypopnea syndrome: the situation in Navarra (Spain)].

OBJECTIVE: To assess the diagnosis and treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS) in Navarra (Spain) and to know the characteristics of patients treated with nasal continuous positive airway pressure (n-CPAP) in our community. METHOD: All patients receiving nasal n-CPAP from the public health service of Navarra in July 2000 were enrolled. A nurse visited each patient and filled in a form with epidemiological data, and patient and clinical characteristics. The nurse then measured CO in expired air and the n-CPAP pressure used and recorded the hour counter reading on the n-CPAP device. Between one and two months later and without prior warning, the patient was once again contacted and a second visit was made. The counter was read again and expired CO was measured. RESULTS: The prevalence of treatment with n-CPAP in Navarra was 125/100,000 inhabitants, and a gradual increase in annual prescriptions was observed. Home visits were made to 535 patients (80.7% of the total). Pneumologists wrote 83.5% of the prescriptions. n-CPAP was used a mean 6.1 hours/day, and the numbers of declared and real hours of use were statistically correlated. The mean apnea-hypopnea index was 51.5, although results were not available for 4.2% of the patients. The treatment was well tolerated according to 83.7% of the patients and 24.8% had been following it for over four years. The pathology most often associated with OSAHS was obesity (73.4% of the patients), followed by high blood pressure (40%); 299 patients (55.8%) had two or more associated diseases and 54 (9.7%) had none. Conventional polysomnography was the diagnostic method used in 45.9% of the cases, and respiratory polygraphs were available for 49.7%. Pressure was adjusted with the aid of polysomnography for 19.4% patients, whereas 32.1% had undergone no testing. Side effects of treatment were reported by 50.8%. CONCLUSIONS: a) The prevalence of n-CPAP treatment in Navarra is high and prescriptions are increasing; b) patient tolerance of and compliance with therapy are good, c) polysomnographs or respiratory polygraphs are available for diagnosis of OSAHS in most cases but the n-CPAP pressure level is adjusted without the recommended studies for many patients.

Angiolymphoid hyperplasia with eosinophilia affecting the oral mucosa: report of a case and a review of the literature.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon disorder of unknown aetiology. Clinically, it is characterized by cutaneous papules or nodules on the head and neck, and extracutaneous involvement is rare. We report a 30-year-old woman who had an asymptomatic submucosal nodule on the upper lip, which histopathologically showed features of ALHE, and review the previously described 15 cases of oral ALHE.

Evolution of a case of lung plasma cell granuloma.

Plasma cell granuloma, on lung inflammatory pseudotumour, is a localized benign proliferation of plasma cells and mesenchymal cells. We report the case of a 45 yr old male, who first presented with mild pain in the left side of the chest. Chest radiography was normal. Eight weeks later he had more pain and an opacity in the left and lower zones of his left chest. After another 7 weeks he had fever and cough with yellowish-green sputum. Chest X-ray then showed a round density in the left upper lobe. The final diagnosis was established after thoracotomy histological examination.

[Endobronchial tuberculosis].

Eight hospitalized patients with endobronchial tuberculosis are reported. Diagnosis was reached in six patients by the demonstration of acid-alcohol resistant bacilli in the bronchial aspirate. In the fifth patient microscopic examination of the bacteria in the liquid obtained by aspiration of a paraspinal abscess was positive. In the last patient diagnosis was established by the positive growth in Lowenstein's medium of lymph node extracts. The clinical, radiologic, endoscopic and microbiologic features are discussed.

[Marking pulmonary nodules with a spiral harpoon using computerised tomography, for resection by minimally invasive surgery].

BACKGROUND: To show the efficacy of placing a spiral harpoon in pulmonary nodules under the control of computerised tomography for their subsequent resection by minimally invasive surgery. MATERIALS AND METHODS: Fifteen nodules of between 0.5-1.5 cm were localised in fifteen patients, of whom ten had antecedents of neoplasia, with the placement of spiral harpoon model Somatex, of 120 mm length and 18 G of Laboratorios Léleman, S.L., by means of computerised tomography, resecting them by minimally invasive surgery. RESULTS: Following the resection of the nodule it was confirmed that in the fifteen cases the harpoon was next to the nodule or encompassing it -- just as it had been placed on the scanner, in two cases objectifying a small intraparenchymatose haemorrhage and in one case a small pneumothorax. The time taken to place the harpoon oscillated between fifteen and thirty minutes. CONCLUSION: Marking a pulmonary nodule with a spiral type harpoon is a simple method that makes it possible to securely anchor the nodule for its subsequent resection by minimally invasive surgery.

[Evolution of the epidemiological characteristics of tuberculosis in Navarra (1994-2003)].

AIM: To describe the changes in the incidence and the epidemiological profile of tuberculosis in Navarra. METHODS: The cases of tuberculosis in the 1994-2003 period were analysed. Cases reported to the system of obligatory notifiable diseases, completed with the microbiological diagnoses and the cases collected in other health registers. RESULTS: The incidence of tuberculosis fell from 21 per 100,000 inhabitants in the five-year period 1994-1998 to 16 per 100,000 in 1999-2003. In both periods the number of cases in men doubled that in women, and the maximum incidence occurred in the age groups from 25 to 44 and over 65 years of age. The diagnoses of tuberculosis in persons with HIV infection fell from 15.1% to 6.6% and those in immigrants rose from 2.2% to 21.3%. Somewhat over 3% of the cases had received prior anti-tuberculosis treatment and about 6% showed resistance to some medicine, without significant differences between periods. The proportion of potentially transmissible tuberculosis (73%) underwent no significant changes, nor did that of those with positive sputum bacilloscopy. The number of outbreaks (groupings of two or more cases) rose from 18 to 26 and the percentage of cases secondary to another recent case rose from 3.6% to 10.1% (p<0,001). In the 1999-2003 period, pulmonary localisation occurred in isolated form in 67.7% of the patients, and in combination with other localisations in another 5.1%. The isolated pleural form appeared in 9.9% and the meningeal form in 1.5%. CONCLUSION: There has been an advance in the control of tuberculosis although its incidence is still high with respect to other European countries. Control of imported cases is one of the challenges to be faced in coming years, without neglecting control measures in the autochthonous population.
