A rare case of Pancoast's syndrome caused by non-Hodgkin's lymphoma is reported. The diagnosis was made on the grounds of examination of the tissue obtained by pulmonary needle biopsy. The necessity of accurate histologic diagnosis and immunohistochemical study is emphasized.

Background: Normal diagnosis of clubbing is clinical; however use of objective criteria may improve the accuracy of findings Objective: To present a simple method of obtaining finger images for the purpose of studying clubbing. Method: Shadow images of the index fingers obtained by projection through a transparent glass plate virtually without distortion and displayed on a common sheet of paper yielded the profile (PA) and hyponychial (HA) angles; as well as the ratio between distal phalangean and interphalangean depths (DPD/IPD). Upon physical examination of 306 adult bearers of pulmonary disease, 116 disclosed presence of clubbing (YES); 126 absence (NO); and 64 were doubtful cases (DBT). Also studied were 452 normal adult individuals. Among these 71.0% of the bearers and 33.4% of the controls were smokers. Results: Values found in normal individuals and in patients bearers of clubbing (YES) were, respectively, 172.8±5.9º vs. 183.4±5.9º for PA, 181.5±5.0º vs. 201.4±6.5º for HA, and 0.904±0.029 vs. 1.014±0.062 for DPD/IPD (significant differences, p<0.001). In the doubtful) cases (DBT) the three values were also higher than in normal controls (p<0.001). Furthermore, it was shown that among controls PA, HA and the DPD/IPD ratios were significantly larger in male smokers (p<0.005) while only the DPD/IPD ratio was larger in female smokers (p<0.05). Conclusions: This is a simple method of obtaining clear index finger images. The hyponychial angle determined on the images was the most useful measurement to discriminate digits clinically with and without clubbing (sensitivity of 76.7%, specificity of 83.2%, predictive positive value of 95.5% and predictive negative value of 96.9%).

Objective: To objectively evaluate the reversal of digital clubbing (DC) in a series of surgically treated lung cancer patients, and to review the literature on the subject. Methods: Sixty-one patients with non-small cell lung cancer-40 with and 21 without DC-were treated by pulmonary resection. Eleven (18%) received additional postoperative radiation therapy. Preoperatively, as well as on postoperative days 7, 18, and 90, the hyponychial angle (HA) and the distal phalangeal depth/interphalangeal depth (DPD/IPD) ratio were determined on profile shadow projections of the index fingers. A review of the literature on reversal of DC (1954-2007) was also performed. Results: From the preoperative period to postoperative day 90, HA decreased from 200.5 ± 5.0° to 193.3 ± 6.8° (p < 0.001), and the DPD/IPD ratio decreased from 1.014 ± 0.051 mm to 0.956 ± 0.045 mm (p < 0.001) in the group of 40 patients with DC. The HA and the DPD/IPD ratio decreased in 33 (82.5%) but remained the same in 7 (1.7%), 6 with unfavorable evolution. In the 21 patients without DC, HA (184.5 ± 5.5°) and the DPD/IPD ratio (0.937 ± 0.046 mm) remained unchanged after surgery. In the literature (1954-2007), we found 52 cases, 5 of which were lung cancer cases, in which reversal of DC, observed in several clinical conditions, was explicitly reported. Conclusion: In most lung cancer patients, DC resolves after effective surgical treatment of the tumor, as can occur in patients with other conditions.

Background: Bronchiectasis is a frequently found disease in medical practice in Brazil leading to significant morbidity and decrease in quality of life of the affected individuals. Objectives: To study diagnostic and therapeutic aspects in a series of hospitalized patients with bronchiectasis in a department of pulmonary diseases. Methods: Signs, symptoms, microbiological and radiographic data, and therapeutic results were studied in 170 hospitalized patients between 1978 and 2001 - females 62.4%, males 37.6%, and aged from 12 to 88 years (mean age 36.8 yrs). Previous history of pneumonia in childhood was detected in 52.5% of the patients, tuberculosis in 19.8%; 8.8% had bronchial asthma, and 2 had Kartagener's syndrome. Results: The most common symptoms were cough (100.0%), expectoration (96.0%) and pulmonary rales (66.0%). The pulmonary lesions were unilateral in 46.5% of the cases. Pneumococcus, H. influenzae or mixed flora were found in 85.0% of the examined sputa. All 170 patients received antibiotics and postural drainage, and 88 of them (younger and with a higher functional reserve) were also submitted to pulmonary resections (82 unilateral and 6 bilateral). Two deaths occurred, and repetitive hospitalizations were more frequent among the clinically treated patients. The follow up showed that most of the surgically treated patients had significant symptoms improvement and rarely needed to be re-hospitalized. Conclusions: In the majority of the patients, lung resection surgery improved permanently the prolonged bronchopulmonary symptoms of patients with bronchiectasis, differently from the patients who received only clinical treatment.

Objective: To relate the experience of the staff at a health care facility specializing in the management of patients with aspiration lung abscess. Methods: Diagnostic aspects and therapeutic results of 252 consecutive cases of lung abscess seen in patients hospitalized between 1968 and 2004. Results: Of the 252 patients, 209 were male, and 43 were female. The mean age was 41.4 years, and 70.2% were alcoholic. Cough, expectoration, fever and overall poor health were seen over 97% of patients. Chest pain was reported by 64%, 30.2% presented digital clubbing, 82.5% had dental disease, 78.6% reported having lost consciousness at least once, and 67.5% presented foul smelling sputum. In 85.3% of the patients, the lung lesions were located either in the posterior segments of the upper lobe or in the superior segments of the lower lobe, and 96.8% were unilateral. Concomitant pleural empyema was seen in 24 (9.5%) of the patients. Mixed flora was identified in the bronchopulmonary or pleural secretions of 182 patients (72.2%). All patients were initially treated with antibiotics (mainly penicillin or clindamycin), and postural drainage was performed in 98.4% of cases. Surgical procedures were performed in 52 (20.6%) of the patients (drainage of empyema in 24, pulmonary resection in 22 and drainage of the abscess in 6). Cure was obtained in 242 patients (96.0%), and 10 (4.0%) died. Conclusion: Lung abscess occurred predominantly in male adults presenting dental disease and having a history of loss of consciousness (especially as a result of alcohol abuse). Most of the patients were treated clinically with antibiotics and postural drainage, although some surgical procedure was required in one-fifth of the study sample.
