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.

Leptospirosis is an infectious disease characterized by multisystemic involvement. The lung involvement is common, usually mild and frequently neglected. When respiratory manifestations are prominent in a patient with leptospirosis, there is the potential for diagnostic confusion. The authors report a severe case of leptospiral pneumonia, with the objective of highlighting this etiological possibility of community pneumonia, especially when there is suspicion of epidemic features.

Chronic eosinophilic pneumonia is a rare disease of unknown cause characterized by eosinophilic alveolar and interstitial infiltration. The authors describe the case of a 49-year-old caucasian woman, presenting dyspnea on minimum effort, with insidious beginning and progressive course in the last six months. The main findings were serum eosinophilia and in the sputum, chest radiographs showing multifocal infiltrations of irregular distribution in both lungs and a restrictive functional impairment. The patient was submitted to an open lung biopsy, which demonstrated a chronic eosinophilic pneumonia. There was a dramatic clinical, radiological, and functional response after corticosteroid therapy.

Objective: Staphylococcal pneumonia typically presents high rates of morbidity and mortality. It typically occurs in cases of influenza (airborne transmission) or during episodes of bacteremia (blood-borne transmission). Methods: A retrospective and descriptive study was conducted in patients admitted to our hospital between January of 1992 and December of 2003. All of he patients included had been diagnosed with community-acquired pneumonia caused by Staphylococcus aureus. All were older than 14 years of age, and none were intravenous drug users. Results: Community-acquired pneumonia was identified in 332 cases, of which 24 (7.3%) were identified as cases of staphylococcal pneumonia. Age ranged from 14 to 89 years. Fifteen patients were male, and nine were female. Twelve patients met the criteria for severe pneumonia. Chest X-rays showed unilateral consolidation in 14 cases, bilateral consolidation in 10, pleural effusion in 15, rapid radiological progression of pulmonary lesions in 14, cavitation in 6 and pneumothorax in 1. Most of the patients presented comorbidities, of which diabetes mellitus was the most common. Twelve patients presented complications such as empyema and septic shock. Four patients died, translating to a mortality rate of 16.6% in our sample. Conclusions: The clinical presentation of pneumonia caused by S. aureus is similar to that of pneumonia caused by other etiological agents. Radiological findings, epidemiological data and risk factors provide important clues to the diagnosis. These factors are important for clinical suspicion, since S. aureus is not typically addressed in empirical treatment.

Objective: To describe the characteristics of patients with influenza A (H1N1)-associated pneumonia treated at two hospitals in the region of Liguria, Italy, as well as to describe their treatment and outcomes. Methods: This was a prospective observational study including all patients older than 16 years of age with a confirmed diagnosis of influenza A (H1N1) who were admitted to Villa Scassi Hospital, in the city of Genoa, Italy, or to the Sestri Levante General Hospital, in the city of Sestri Levante, Italy, between September of 2009 and January of 2010. The primary outcome measure was mortality within 60 days after diagnosis. Secondary outcome measures were the need for mechanical ventilation and the length of hospital stay. Results: Of the 40 patients with a confirmed diagnosis of influenza A (H1N1), 27 presented pneumonia during the study period. The mean age of the 27 patients was 42.8 ± 14.8 years, and the mean length of hospital stay was 11.6 ± 8.2 days. Of the 27 patients, 20 had respiratory failure, 4 underwent invasive mechanical ventilation, and 5 underwent noninvasive ventilation. One patient had comorbidities, developed multiple organ failure, and died. Conclusions: During the influenza A (H1N1) pandemic, the associated mortality rate was lower in Italy than in other countries, and cases reported in the country typically had a milder course than did those reported elsewhere. Nevertheless, 9 of our cases (33%) rapidly evolved to respiratory failure, requiring mechanical ventilation.

48 years-old woman, asymptomatic, presented with radiographic findings of patchy airspace consolidation with nodular opacities in the upper right lobe, middle lobe and lingula. The differential diagnoses of neoplasms, sarcoidosis, granulomatous diseases and tuberculosis were considered. Diagnosis of Bronchiolitis obliterans organizing pneumonia was made by means of videothoracoscopy whereupon treatment with corticosteroids was begun. The patient had a positive evolution with resolution of the radiographic finding.

Pneumocystosis is an opportunistic infection that occurs frequently in immunodeficient patients, mainly in those with the acquired immunological deficiency (AIDS). The authors report the case of a patient with insidious symptoms of fever, cough, and weight loss. Thorax radiography revealed a tumoral image in the right costophrenic angle. Treatment for tuberculosis (therapeutic test) presented no response. An open lung biopsy was performed and the histological examination revealed Pneumocystis carinii pneumonia. The patient presented significant clinical and radiological improvement with specific treatment.

Keywords: pneumocystis carinii pneumonia; AIDS-related opportunistic infections

Objective: To determine the frequency of HRCT findings and their distribution in the lung parenchyma of patients with organizing pneumonia. Methods: This was a retrospective review of the HRCT scans of 36 adult patients (26 females and 10 males) with biopsy-proven organizing pneumonia. The patients were between 19 and 82 years of age (mean age, 56.2 years). The HRCT images were evaluated by two independent observers, discordant interpretations being resolved by consensus. Results: The most common HRCT finding was that of ground-glass opacities, which were seen in 88.9% of the cases. The second most common finding was consolidation (in 83.3% of cases), followed by peribronchovascular opacities (in 52.8%), reticulation (in 38.9%), bronchiectasis (in 33.3%), interstitial nodules (in 27.8%), interlobular septal thickening (in 27.8%), perilobular pattern (in 22.2%), the reversed halo sign (in 16.7%), airspace nodules (in 11.1%), and the halo sign (in 8.3%). The lesions were predominantly bilateral, the middle and lower lung fields being the areas most commonly affected. Conclusions: Ground-glass opacities and consolidation were the most common findings, with a predominantly random distribution, although they were more common in the middle and lower thirds of the lungs.

Most interstitial lung diseases (ILD) are indolent in nature, producing subacute or chronic symptoms that progress at various rates and are usually present for months to years before a diagnosis is established. This report describes a case of a fulminating and life-threatening variant of idiopathic bronchiolitis obliterans with organizing pneumonia (BOOP). Early suspicion, histologic diagnosis, and prompt initiation of corticosteroid therapy is important to prevent mortality.

Organized pneumonia secondary to amiodarone use is rare. Only eight cases have been reported in the literature. It is reported on the case of a 75-year-old female who, after a cumulative dose of 43 g of amiodarone, presented coughing, progressive dyspnea and bilateral infiltrates seen at thoracic radiographs. Transbronchial biopsy confirmed the diagnosis. As the drug was discontinued, there was functional and clinical improvement.

Nosocomial pneumonia, especially ventilator-associated pneumonia, is a common infection in ICUs. The main etiologic factors involve colonizing and opportunistic bacteria from the oral cavity. Oral hygiene measures, including the use of oral antiseptic agents, such as chlorhexidine, have proven useful in reducing its incidence. The objective of this article was to review the literature on the importance of the oral environment in the development of nosocomial pneumonia.

Psittacosis, also known as ornithosis, is a disease caused by Chlamydia psittaci. The most common clinical presentation is insidious onset, mild symptoms resembling a nonspecific viral illness and preference for the lungs. It is rarely a systemic and fatal disease. It is described a rare case of pneumonia due to Chlamydia psittaci that progressively developed into respiratory failure, requiring mechanical ventilation. It is very important to consider psittacosis in cases of atypical pneumonia whose evolution is unsatisfactory, with no response to antimicrobial therapy and epidemiology is positive for exposure to birds. Prompt recognition is vital as the response to appropriate treatment is excellent. Delayed diagnosis may lead to a severe course and fatal outcome.

Keywords: Mycoplasma pneumonia. Ornithosis.

A 50-year-old woman with chagasic esophageal achalasia and megacolon presented with nonproductive cough, chest pain and dyspnea. A chest X-ray showed bilateral opacity suggestive of lobar pneumonia. Open lung biopsy revealed lipoid pneumonia resulting from aspiration of mineral oil from a mineral oil-based laxative that the patient had been taking regularly for the last three years. The authors discuss concomitance of chagasic megacolon and esophageal achalasia with lipoid pneumonia and make recommendations regarding the use of mineral oil-based products by these patients.

Objective: To describe the results of the surgical treatment of children with necrotizing pneumonia. Methods: A retrospective analysis of the medical charts of 20 children diagnosed with necrotizing pneumonia and submitted to surgical treatment between March of 1997 and September of 2008 in the thoracic surgery departments of two hospitals in the city of Manaus, Brazil. We compiled data regarding age, gender, etiologic agent, indications for surgery, type of surgical resection performed, and postoperative complications. Results: The mean age of the patients was 30 months. Of the 20 patients studied, 12 (60%) were female. The most common etiologic agents were Staphylococcus aureus, in 5 patients (25%), and Klebsiella sp., in 2 (10%). The indications for surgery were sepsis, in 16 patients (80%), and bronchopleural fistula, in 4 (20%). The types of surgical procedures performed were lobectomy, in 12 patients (60%), segmentectomy, in 7 (35%), and bilobectomy, in 1 (5%). There were 8 patients (40%) who also underwent decortication. The postoperative complications were as follows: bronchopleural fistula, in 4 patients (20%); empyema, in 1 (5%); pneumatocele, in 1 (5%); and phlebitis of the left arm, in 1 (5%). Four (20%) of the patients died. Conclusions: Surgical resection should be considered in patients with evidence of pulmonary necrosis. Resection is indicated in cases of severe sepsis, high output bronchopleural fistula, or acute respiratory failure that are refractory to clinical treatment.

Objective: To describe aspects found on HRCT scans of the chest in patients infected with the influenza A (H1N1) virus. Methods: We retrospectively analyzed the HRCT scans of 71 patients (38 females and 33 males) with H1N1 infection, confirmed through laboratory tests, between July and September of 2009. The HRCT scans were interpreted by two thoracic radiologists independently, and in case of disagreement, the decisions were made by consensus. Results: The most common HRCT findings were ground-glass opacities (85%), consolidation (64%), or a combination of ground-glass opacities and consolidation (58%). Other findings were airspace nodules (25%), bronchial wall thickening (25%), interlobular septal thickening (21%), crazy-paving pattern (15%), perilobular pattern (3%), and air trapping (3%). The findings were frequently bilateral (89%), with a random distribution (68%). Pleural effusion, when observed, was typically minimal. No lymphadenopathy was identified. Conclusions: The most common findings were ground-glass opacities and consolidations, or a combination of both. Involvement was commonly bilateral with no axial or craniocaudal predominance in the distribution. Although the major tomographic findings in H1N1 infection are nonspecific, it is important to recognize such findings in order to include infection with the H1N1 virus in the differential diagnosis of respiratory symptoms.
