Tracheobronchial foreign body aspiration in adults is rare when compared to children. In this case report, 76 year old female patient who aspirated a screw of tracheostomy cannula which was taken out by fiberoptic bronchoscopy (FOB) was presented. This case showed us that education of patients about stoma care is important. The FOB can be used safely to get foreign body from distal airways.
A rare case, a case of endobronchial metastasis from urinary bladder carcinoma is reported. A 70 years-old man was admitted with hematuria. He has a mass in urinary bladder and a mass in lung. He has no pulmonologic symptom. He is a smoker with 75 pack-years. Thorax computerized tomography revealed a mass in left lung upper lobe. Bronchoscopy demonstrated an endobronchial tumor in left upper lobe, apikoposterior segment. Histopathologically diagnosis was endobronchial metastasis from urinary bladder carcinoma. He received five courses of chemotherapy (cisplatin + gemcitabine). The mass was regressed after three months. Our patient lived for one year from diagnosis.
This study is aimed to evaluate the incidence of silicosis and the relation of it with personal and work-related factors among workers exposed to silica in ceramic factory. Workers were evaluated by respiratory symptoms, physical examination, pulmonary function and radiological findings. Occupational and Enviromental Pulmonary Disease Evaluation Questionnaire of the Turkish Thoracic Society Enviromental and Occupational Pulmonary Diseases Working Group was used. 365 of 626 workers had exposure to silica and the rest 261 were concerned as control group. There was no difference between mean age, duration of work and smoking pack year among the groups (p> 0.05). Cough and sputum rates were higher in silicosis group FEV1 and FVC values were lower in silica group but this was not statistically significant. When the two subgroups of silica group (the workers in high dust concentration and the ones in low concentration) were compared, the high concentrated group had significantly more sputum but the other symptoms and pulmonary functional parameters were not different significantly. 24 workers had parenchymal densities adjusted with pneumoconiosis. The workers with the pneumoconistic finding, had a higher mean age and longer duration of work. As a conclusion, ceramic industry has risk for silicosis. And the risk increase by time and age.
Though the high incidence of pancreatic metastasis of lung cancer has been reported in autopsy series, symptomatic cases with jaundice due to that is very rare. Dominant histological type with pancreatic metastases is small cell carcinoma and prognosis is poor. Hereby, we report a case initially presenting with gastroenterologic symptoms as jaundice, nausea, vomiting, weight loss and abdominal pain and then diagnosed as primary small cell carcinoma of the lung with metastasis to pancreas. He underwent a palliative surgery due to obstructive jaundice. This presented case is a rare one with its priority of gastroenterologic symptoms rather than pulmonary complaints.
Recent studies suggest that thoracal high resolution computed tomography (HRCT) of the thorax can detect the irreversible structural changes in chronic asthma cases. This study is aimed to evaluate these possible changes and their relation with asthma severity. Twenty-eight stable asthmatic patients with normal conventional radiography and 10 healthy controls were included. Twenty of the patients were female (71.4%) and the mean age of the group was 43 +/- 10.5 (30-61). The groups were divided into 2; as group 1 included mild intermittent and mild persistent cases, and group 2 included moderate and severe persistent cases. Asthma and control group, and group 1 and 2 were compared according to the thickness of airwall (T), thickness to outer diameter (T/D), wall area (WA), the percentage wall area (WA%). HRCT showed that air trapping, bronchiectasis, fibrotic lesions and airwall thickening were significantly more common in asthma group (p< 0.05). Emphysema, acinar pattern, collapse and mucoid impact were common in asthma group (p> 0.05). The incidence of T and WA was higher in asthma group but also did not reach statistical significance and the thickening of airwall in small airways was significantly more in asthma group. Any correlation between HRCT findings and asthma severity was not found. So reversible and irreversible bronchial and parenchymal changes, detected by HRCT but not by plain chest radiograms, may be present in asthma cases. The early detection of these changes may lead more aggressive asthma management.
