Objective: The aim of this study was to use a Serbian-language version of the disease-specific, self-report Sarcoidosis Health Questionnaire (SHQ), which was designed and originally validated in the United States, to assess health status in sarcoidosis patients in Serbia, as well as validating the instrument for use in the country. Methods: This was a cross-sectional study of 346 patients with biopsy-confirmed sarcoidosis. To evaluate the health status of the patients, we used the SHQ, which was translated into Serbian for the purposes of this study. We compared SHQ scores by patient gender and age, as well as by disease duration and treatment. Lower SHQ scores indicate poorer health status. Results: The SHQ scores demonstrated differences in health status among subgroups of the sarcoidosis patients evaluated. Health status was found to be significantly poorer among female patients and older patients, as well as among those with chronic sarcoidosis or extrapulmonary manifestations of the disease. Monotherapy with methotrexate was found to be associated with better health status than was monotherapy with prednisone or combination therapy with prednisone and methotrexate. Conclusions: The SHQ is a reliable, disease-specific, self-report instrument. Although originally designed for use in the United States, the SHQ could be a useful tool for the assessment of health status in various non-English-speaking populations of sarcoidosis patients.

Objetivo: Realizar a tradução para a língua portuguesa e a adaptação cultural para uso no Brasil do Quality of Communication Questionnaire (QOC) para pacientes com DPOC em cuidados paliativos. Métodos: Após a aprovação do autor do questionário e do comitê de ética da instituição, a versão original do QOC com 13 itens foi traduzida, de forma independente, por dois tradutores brasileiros com fluência na língua inglesa. Uma síntese das duas traduções foi realizada por uma médica bilíngue e os dois tradutores, que chegaram a um consenso, gerando uma versão na língua portuguesa. Essa versão foi retraduzida por dois tradutores nativos de países de língua inglesa com fluência na língua portuguesa. Para resolver quaisquer discrepâncias, um comitê de especialistas comparou a versão original com todas as versões produzidas e, assim, obteve-se a versão pré-final do QOC. O pré-teste foi aplicado em 32 pacientes internados em UTIs de três hospitais públicos da grande Florianópolis (SC) para avaliar a clareza e a aceitabilidade cultural da versão pré-final do QOC. Resultados: A média de idade dos pacientes foi de 48,5 ± 18,8 anos. A maioria dos itens foi bem compreendida e aceita, recebendo pontuações ≥ 8. Um item, sobre morte, suscitou dificuldades na compreensão dos participantes do pré-teste. Ao submeter a retradução ao autor do QOC, ele solicitou alterações em dois itens, que foram acatadas. Após essas alterações, a versão final foi aprovada. Conclusões: A tradução e a adaptação cultural do QOC para uso no Brasil foi concluída com sucesso.

The objective of this study was to provide access to and disseminate a questionnaire used as an instrument to assess the organizational elements and the performance of primary health care clinics regarding TB control in Brazil, comparing selected organizational dimensions by health care clinic, by municipality and by actor (patients, health care workers and managers). The results show that municipalities where the coverage of supervised treatment was more extensive presented more favorable indicators regarding access to TB treatment. The organizational format of the health care clinics involved in TB treatment-family health programs and referral centers with specialized teams in TB control programs (TCPs)-was not a factor that expanded access to diagnosis. The TCPs involving a smaller number of patients presented better performance regarding the health care professional-patient relationship. The majority of the patients faced economic and social difficulties, and most managers were unaware of the amount of resources allocated to TB control activities. The instrument proved to be viable and to have the potential to adequately assess the performance of health care clinics in the urban areas studied.

In a 62-year-old white woman, submitted to preoperative evaluation for facectomy, urinary alterations were detected. The diagnosis established included left-sided kidney stones and homolateral exclusion. At pre-nephrectomy, interstitial widespread lung disease and thoracic adenopathy were evidenced and their investigation was postponed to after surgery. In the removed kidney, non cascous epithelioid granulomas were found. Later, transbronchial biopsy disclosed this same aspect. The patient was treated with methylprednisolone and presented slight pulmonary improvement, though no amelioration in renal function occurred. Final diagnosis was sarcoidosis with lung, thoraco-lymphatic and renal involvement.

Objective: To determine the prevalence of bronchial asthma among university hospital employees between the ages of 20 and 44 based on the criteria established in the European Community Respiratory Health Survey. Methods: A descriptive, prospective, randomized, stratified prevalence study was conducted, in which questionnaires completed between April and October of 2002 by 351 employees of the Universidade Federal de Pernambuco (Federal University at Pernambuco) Hospital das Clínicas were evaluated. For sample characterization, the independent variables used were the signs and symptoms of asthma, and one dependent variable (physician-diagnosed asthma, characterized by data related to attacks occurring within the 12 months preceding the study) was included. Results: The prevalence of asthma was 10.7%. Nocturnal dyspnea, chest tightness and nocturnal cough were the most frequent symptoms, although statistically significant correlations with asthma were found exclusively among females (p = 0.03, p = 0.04 and p = 0.001, respectively). Nocturnal dyspnea, wheezing within the last 12 months, dyspnea with wheezing and the use of asthma medication were more frequent among individuals between 20 and 29 years of age. The last two variables presented statistical significance (p < 0.001). Undertreatment of asthma was identified in 35 (10.7%) of the cases. Conclusions: The results of this pioneering study show that asthma prevalence in a sample composed of employees of a university hospital located in a developing country was slightly higher than that found in the literature and suggest that working in a university hospital does not reduce the frequency of undertreatment.

Objective: To translate the King's Brief Interstitial Lung Disease (K-BILD) questionnaire to Portuguese and culturally adapt it for use in Brazil. The K-BILD quantifies the health status of patients with ILD. Methods: The process involved the following steps: authorization from the author of the original (English-language) questionnaire; translation of the questionnaire to Portuguese by three translators, working independently; merging of the translations by a committee of specialists; back-translation of the questionnaire to English; revision and readjustment of the back-translation by the committee of specialists; evaluation by the original author; revision of the back-translation; cognitive debriefing (verification of the clarity and acceptability of the Portuguese-language version in the target population-i.e., patients with ILD); and finalization of the Portuguese-language version. Results: In the cognitive debriefing step, 20 patients with ILD were interviewed. After the interviews, the clarity and acceptability index of each question was ≥ 0.8, which is considered acceptable. Conclusions: The Portuguese-language version of K-BILD appears to be easily administered to and understood by patients with ILD in Brazil. To our knowledge, this is the only instrument in Brazilian Portuguese that is designed to evaluate the impact that ILD has on the various aspects of the lives of those it affects.

Sarcoidosis is a multisystem inflammatory disorder of unknown cause. It most commonly affects the pulmonary system but can also affect the musculoskeletal system, albeit less frequently. In patients with sarcoidosis, rheumatic involvement is polymorphic. It can be the presenting symptom of the disease or can appear during its progression. Articular involvement is dominated by nonspecific arthralgia, polyarthritis, and Löfgren's syndrome, which is defined as the presence of lung adenopathy, arthralgia (or arthritis), and erythema nodosum. Skeletal manifestations, especially dactylitis, appear mainly as complications of chronic, multiorgan sarcoidosis. Muscle involvement in sarcoidosis is rare and usually asymptomatic. The diagnosis of rheumatic sarcoidosis is based on X-ray findings and magnetic resonance imaging findings, although the definitive diagnosis is made by anatomopathological study of biopsy samples. Musculoskeletal involvement in sarcoidosis is generally relieved with nonsteroidal anti-inflammatory drugs or corticosteroids. In corticosteroid-resistant or -dependent forms of the disease, immunosuppressive therapy, such as treatment with methotrexate or anti-TNF-, is employed. The aim of this review was to present an overview of the various types of osteoarticular and muscle involvement in sarcoidosis, focusing on their diagnosis and management.

Pulmonary cavitation is rather uncommon in patients with sarcoidosis, and aspergilloma is even more uncommon in such cases. Here, we present the case of a 63-year-old female patient with cavitary lung disease who had been under treatment for TB for 9 months. A diagnosis of pulmonary sarcoidosis was established based on the fiberoptic bronchoscopy finding of noncaseating granuloma. Treatment with corticosteroids led to a dramatic improvement in symptoms. While under treatment for sarcoidosis, the patient developed an aspergilloma. She presented immediate skin test reactivity to Aspergillus fumigatus, as well as positivity for A. fumigatus serum precipitins. This is the first reported case of aspergilloma formation in a patient with cavitary sarcoidosis in India.

A pneumonia por Pneumocystis carinii (PPC), que é a infecção oportunista que mais comumente põe em risco a vida de pacientes com síndrome da imunodeficiência adquirida (SIDA), tem sido há bastante tempo associada a outros estados de imunodeficiência. Os relatos iniciais sugeriram que a apresentação clínica da PPC em SIDA difere de sua apresentação em outras situações, embora ambas tenham sofrido modificações nos últimos anos. O objetivo do presente estudo é comparar os achados clínicos e laboratoriais da PPC em SIDA com os de pacientes portadores de PPC sem SIDA. Foram revisados os prontuários médicos de todos os pacientes em nossa instituição que tiveram o diagnóstico confirmado de PPC e SIDA durante o ano de 1994 (17 pacientes) e sem SIDA no período de 1992-1994 (dez pacientes). Quando da apresentação, os pacientes sem SIDA tinham uma duração de sintomas significativamente menor (8,4 ± 7,7 vs 19,5 ± 10,2 dias, p < 0,05), menor PaO2 média a ar ambiente (47 ± 8,2 vs 63 ± 10mmHg, p < 0,05), e mais freqüente infiltrado unilateral no radiograma do tórax (60 vs 6%, p < 0,05). O índice de mortalidade da PPC foi marcadamente maior nos pacientes sem SIDA (40 vs 6%, p < 0,05), e este fato estava associado com retarde no início do tratamento específico nestes pacientes. Devido a seu curso mais agudo, apresentação radiológica atípica e alto índice de mortalidade, concluímos que o diagnóstico de PPC deve ser afastado em pacientes que recebem terapia imunossupressora e que profilaxia anti-PPC deve ser fortemente considerada em pacientes que serão imunossuprimidos.

Although hemophagocytic syndrome is a rare clinical condition, it is associated with high mortality and the number of cases described in the literature has progressively increased. The diagnosis of hemophagocytic syndrome is made on the basis of a finding of hemophagocytosis. Sarcoidosis is a highly prevalent disease whose course and prognosis might correlate with the initial clinical presentation and the extent of the disease. We report the case of a patient with long-standing sarcoidosis who presented with intermittent fever and fatigue. The diagnosis of hemophagocytic syndrome was made by bone marrow aspiration, and specific treatment was ineffective. This is the third case of sarcoidosis-related hemophagocytic syndrome reported in the literature and the first reported in Latin America. All three cases had unfavorable outcomes.

Sarcoidosis is a systemic disease of unknown etiology, characterized by noncaseating granulomas. Although it may affect any organ, morbidity and mortality are most commonly related to pulmonary involvement, which is found in 80-90% of patients. This study illustrates the principal manifestations of sarcoidosis seen in high-resolution computed tomography scans, including typical as well as atypical forms.

A 27-year-old male patient presented with respiratory symptoms, bilateral enlargement of the cervical lymph nodes and enlarged liver. In the imaging studies, bilateral enlargement of the hilar nodes was observed, together with pulmonary infiltrate. The patient was submitted to lung and liver biopsies, which revealed noncaseating granulomas. The clinical, radiological and histopathological findings were consistent with sarcoidosis and lymph node amyloidosis. The combination of sarcoidosis and amyloidosis has rarely been reported.

Objective: To investigate the significance of cellular immune markers, as well as that of collagen and elastic components of the extracellular matrix, within granulomatous structures in biopsies of patients with pulmonary or extrapulmonary sarcoidosis. Methods: We carried out qualitative and quantitative evaluations of inflammatory cells, collagen fibers, and elastic fibers in granulomatous structures in surgical biopsies of 40 patients with pulmonary and extrapulmonary sarcoidosis using histomorphometry, immunohistochemistry, picrosirius red staining, and Weigert's resorcin-fuchsin staining. Results: The extrapulmonary tissue biopsies presented significantly higher densities of lymphocytes, macrophages, and neutrophils than did the lung tissue biopsies. Pulmonary granulomas showed a significantly higher number of collagen fibers and a lower density of elastic fibers than did extrapulmonary granulomas. The amount of macrophages in the lung samples correlated with FVC (p < 0.05), whereas the amount of CD3+, CD4+, and CD8+ lymphocytes correlated with the FEV1/FVC ratio and VC. There were inverse correlations between TLC and the CD1a+ cell count (p < 0.05), as well as between DLCO and collagen/elastic fiber density (r = −0.90; p = 0.04). Conclusions: Immunophenotyping and remodeling both showed differences between pulmonary and extrapulmonary sarcoidosis in terms of the characteristics of the biopsy samples. These differences correlated with the clinical and spirometric data obtained for the patients, suggesting that two different pathways are involved in the mechanism of antigen clearance, which was more effective in the lungs and lymph nodes.

We report the case of a 41 year-old black woman who presented a sudden infiltration of old scars of her face. These scars were from a car accident 10 years prior. Histological analysis of a skin biopsy revealed non-caseous granulomas consistent with sarcoidosis, and computed tomography of the thorax revealed enlarged mediastinal lymph nodes. The lesions regressed spontaneously and no treatment was required.

Objective: To determine the frequency of and the factors related to delayed diagnosis of sarcoidosis in Brazil. Methods: We evaluated patients with a biopsy-proven diagnosis of sarcoidosis, using a questionnaire that addressed the following: time since symptom onset and since the first medical visit; and the number and specialty of the physicians visited. We divided the patients by the timeliness of the diagnosis-timely (< 6 months) and delayed ( 6 months)-comparing the two groups in terms of systemic and pulmonary symptoms; extrathoracic involvement; spirometric data; radiological staging; level of education; income; and tuberculosis (diagnosis and treatment). Results: We evaluated 100 patients. The median number of physicians consulted was 3 (range, 1-14). In 11 cases, sarcoidosis was diagnosed at the first visit. In 54, the first physician seen was a general practitioner. The diagnosis of sarcoidosis was timely in 41 patients and delayed in 59. The groups did not differ in terms of gender; race; type of health insurance; level of education; income; respiratory/systemic symptoms; extrathoracic involvement; and radiological staging. In the delayed diagnosis group, FVC was lower (80.3 ± 20.4% vs. 90.5 ± 17.1%; p = 0.010), as was FEV1 (77.3 ± 19.9% vs. 86.4 ± 19.5%; p = 0.024), misdiagnosis with and treatment for tuberculosis ( 3 months) also being more common (24% vs. 7%, p = 0.032, and 20% vs. 0%; p = 0.002, respectively). Conclusions: The diagnosis of sarcoidosis is often delayed, even when the imaging is suggestive of sarcoidosis. Delayed diagnosis is associated with impaired lung function at the time of diagnosis. Many sarcoidosis patients are misdiagnosed with and treated for tuberculosis.

Objective: To identify predictive features associated with the course of sarcoidosis at initial evaluation and to develop a predictive score. Methods: This was a retrospective study involving pulmonary sarcoidosis patients, classified as having a self-limited or persistent course of disease, comparing data between the outcomes by univariate analysis. Features related to persistent disease were selected by multivariate analysis and a prognostic score was designed. Results: The sample comprised 200 patients (mean age = 49 years). The median duration of symptoms to diagnosis was 12 months, and delayed diagnosis (> 12 months) was found in 43% of the cases. The most common radiological stage was II; 37% had reduced FVC. Relevant systemic involvement was detected in 37% of the patients. Treatment for tuberculosis was prescribed in 44 patients prior to sarcoidosis diagnosis. Treatment for sarcoidosis was required in 77% of the sample, and the disease course was persistent in 115 cases. Excluding 40 patients with fibrotic disease, prognostic factors to persistent disease were parenchymal involvement, delayed diagnosis, dyspnea, relevant systemic involvement, and reduced FVC. On the basis of the analysis, a 3-letter scoring system (A, B and C) was developed according to the selected factors. The positive predictive values for persistent course for A (= 1 point) and C scores (= 4 points) were 12.5% and 81.8%, respectively. Conclusions: A score can be derived by selected features at initial evaluation, allowing the prediction of outcomes in a significant number of sarcoidosis patients.
