3 - Silicosis among PIT diggers in the region of Ibiapaba, State of Ceará, Brazil: from detection to control

Abstract PDF PT Portuguese Text

Silicosis among pit diggers was first described in 1984. Two years later, a focus of the disease was detected in the region of Ibiapaba, State of Ceará, Brazil. The aims of this study were: 1) to present the educational program to which these workers and their families were submitted; 2) to study, in this population, the impact of the educational program on the knowledge about silicosis and on the behavior changes in the pit digging activity. First, a primary preventing educational intervention (PPEI) was created as per the critical awareness-raising method by Paulo Freire, and applied to this population. Subsequently, the role of PPEI on silicosis control among the pit diggers was studied. In the region there were 1202 pit diggers, and 687 from 5 selected towns were submitted to PPEI. Out of these, 287 workers participated of the second part of the study. All of them were male, ages from 18 to 78 years, 115 were silicotic, 122 non-silicotic, and 46 did not know their health status. Results show that PPEI brought to silicotic and non-silicotic workers a deep knowledge about the relationship between pit digging and silicosis, and induced most of them (85.8%) to quit this activity. PPEI itself promoted an awareness of this population about silicosis, interrupting the epidemiological cycle of the disease in the region of Ibiapaba.

4 - Asthma morbidity and mortality in the State of Parana and in city of Curitiba from 1984 to 1995

Morbimortalidade por asma no Estado do Paraná e município de Curitiba no período entre 1984 e 1995

J Bras Pneumol.1999;25(1):12-16

Abstract PDF PT Portuguese Text

There has been an increase in hospital admissions and mortality rates for asthma in several countries. The objectives of this study were to assess hospital morbidity for asthma in Curitiba and mortality rates for asthma in Curitiba and in the State of Paraná. Hospital admissions for asthma in 1994 and 1995 were analyzed among users of SUS-Sistema Único de Saúde (Public health care system) in Curitiba. The authors verified asthma deaths that occurred from 1984 to 1995 in Curitiba and in the State of Paraná. Specific mortality rates for asthma were obtained through a mortality information system (SIM) of the State and City Departments of Health. Population data were obtained from IPARDES (Institute for Demographic and Statistical Information of the State of Paraná). Hospital admissions for asthma represented 0.8% of total admissions and remained unchanged in 1994 and 1995. Mean mortality rates for asthma was 0.24 ± 0.08/100,000 inhabitants aged 5 to 34 years. In 1989, the mortality rate was greater than the positive standard deviation, but was stable in the remaining years. In Curitiba, the mean mortality rate was 0.39 ± 0.28/100,000. Two peaks occurred in 1984 and 1989, respectively 1.04 and 0.81/100,000. Despite an increase in prevalence of asthma and increasing mortality rates in the past years, Curitiba and the State of Paraná remained with stable rates for ages 5 to 34.

5 - Pulmonary diseases in HIV positive patients. Evaluation of diagnostic techniques

Pneumopatias em pacientes positivos ao vírus da imunodeficiência humana. Avaliação de técnicas diagnósticas

Rosemeri Maurici da Silva, Mário Sérgio Soares de Azeredo Coutinho, Márcia Margaret Menezes Pizzichinni

J Bras Pneumol.1999;25(1):17-24

Abstract PDF PT Portuguese Text

Bronchoscopy with bronchoalveolar lavage, bronchial brush, and transbronchial biopsy are useful methods for the diagnosis of pulmonary diseases in patients infected with the human immunodeficiency virus (HIV). However, data on the accuracy of these techniques are conflicting. In order to estimate the sensitivity of the bronchoalveolar lavage, bronchial and transbronchial biopsy in pulmonary disease diagnosis in patients infected with HIV, the authors studied 71 consecutive patients, most of them with respiratory symptoms up to 15 days (58%) and radiologic signs of interstitial infiltrates (62%). The sensitivity was calculated taking as reference a constructed gold-standard, represented by the sum of all three techniques combined. Sensitivities for bronchoalveolar lavage, transbronchial biopsy, and bronchial brush were 86%, 43% and 5%, respectively. The association of bronchoalveolar lavage and transbronchial biopsy reached the sensitivity to 100%, reflecting how the gold-standard was constructed. The complication rate of the procedures was 3%. These results suggest that, in this population: (1) bronchoscopy with bronchoalveolar lavage, bronchial brush, and transbronchial biopsy are secure procedures with good diagnostic performance; (2) bronchoalveolar lavage alone has reached the highest sensitivity, whereas both bronchoalveolar lavage and transbronchial biopsy can be considered complementary techniques; (3) the association of bronchoalveolar lavage and transbronchial biopsy performed better than bronchoalveolar lavage alone; and (4) the use of bronchial brush in the sequence used in this protocol did not have any influence on the performance of diagnosis.

8 - Malignant pulmonary hemangiopericytoma: report of a case

Hemangiopericitoma pulmonar maligno: relato de caso

Mônica Flores Rick, Sonia Catarina de Abreu Figueiredo

J Bras Pneumol.1999;25(1):50-52

Abstract PDF PT Portuguese Text

The hemangiopericytoma is a rare malignant neoplasia that involves the lungs in about 10% of the cases. It usually presents as a great encapsulated mass in asymptomatic patients. The treatment of choice is surgical resection. The authors present a case of malignant lung hemangiopericytoma in a 62 year-old woman, followed by discussion and review of literature.

9 - Pulmonary microsporidiosis in AIDS: report of a case

Microsporidiose disseminada na AIDS: relato de caso

Aline Elisa Goulart, Agnaldo José Lopes, José Manoel Jansen, Daurita D. Paiva, Márcio Neves Bóia, José Mauro Peralta

J Bras Pneumol.1999;25(1):53-56

Abstract PDF PT Portuguese Text

Microsporidiosis is a rapidly emerging protozoon infection that has been reported predominantly in severely immunosuppressed persons with acquired immunodeficiency syndrome (AIDS). Since the first case of human microsporidian infection was reported in 1956, over 400 cases have been documented. The initial description of microsporidian infection in AIDS patients occurred in 1985. Five genera have been identified as the agents of microsporidiosis in immunocompromised persons (Enterocytozoon, Encephalitozoon, Septata, Pleistophora and Nosema). Respiratory tract infection due to microsporidia is associated almost exclusively with disseminated disease produced by members of the genera Encephalitozoon and Septata. Metronidazole and albendazole were recently reported to be responsible for clinical improvement of patients. The authors reported a case of a woman with AIDS and respiratory symptoms related to two pulmonary pathogens: Mycobacterium tuberculosis and Encephalitozoon cuniculi, identified by polymerase chain reaction (PCR) using diagnostic primers targeting the small subunit ribosomal RNA.
