Thoracic endometriosis is characterised by recurring pulmonary symptoms in association with the menstrual period. Pleural endometriosis manifests itself as recurring pneumothorax or hematothorax while pulmonary endometriosis is characterized by hemoptysis. The pathogenetic mechanism is not completely understood but it appears that hematogenous and lymphangitic embolization of endometrial tissue may play a significant part in parenchymal and pleural endometriosis respectively. Clinical symptoms begin with ovulation. Hemoptysis is explained by sloughing off of decidual tissue and an increased capillary fragility during menstruation. Rupture of pleurally based alveoli in the vicinity of endometrial tissue or necrosis of the diaphragm at the side of diaphragmatic endometrial implants might be causative for the development of a pneumothorax. Therapy of both forms of thoracic endometriosis consists in hormonal suppression but in some cases surgical intervention might become necessary.

A total of 161 patients with lobar or segmental consolidation were examined by realtime ultrasound and Doppler ultrasound. Air bronchograms were detected in 141 patients, fluid bronchograms in 27 patients, and parapneumonic effusion in 74 patients. In 36 patients with necrotizing pneumonia, ultrasound detected microabscesses in 33 (91.7%) compared with the air-fluid levels detected by standard chest radiographs in 20 patients (55.6%; p less than 0.05). Of 31 patients with tumors causing obstructive pneumonitis, 29 (93.5%) had tumors detected by chest ultrasound, whereas only 11 patients (35.5%) had chest radiographs that suggested a tumor was causing the obstructive pneumonitis (p less than 0.05). Chest ultrasound was used to guide thoracentesis for parapneumonic effusion in 65 patients, with a 100% success rate. Twenty-six patients with necrotizing pneumonia underwent ultrasound-guided needle aspiration of microabscesses. The procedure was successful in 24 patients (92.3%), and 21 patients (80.8%) had microbiologic confirmation. Twenty patients with tumor-associated obstructive pneumonitis received needle aspiration biopsy under ultrasound guidance; 19 patients (95.0%) had the histology confirmed. Five patients with malignancy manifesting as pulmonary consolidation underwent a diagnostic ultrasound-guided needle aspiration biopsy. Five patients (3.8%) developed complications of minimal pneumothorax or mild hemoptysis in 132 episodes of needle aspiration. We conclude that ultrasonography is useful for the evaluation of pulmonary consolidation. It can also be used for needle aspiration guidance for etiologic diagnosis of patients with complicated pneumonia.

Two hundred and eighteen patients, with thoracic tumors larger than 3 cm in size, underwent ultrasound-guided percutaneous transthoracic core biopsy with a large-bore Tru-Cut needle. Fifty-five tumors were in the mediastinum, and 122 tumors were located at subpleural area, and 42 tumors were within the lungs. In 122 subpleural tumors, the sensitivity of ultrasound-guided core biopsy for the diagnosis of malignancy was 96.8%, and accuracy was 97.5%. Sensitivity for the diagnosis of malignant tumors located within the lungs was 94.6%, and accuracy was 95.2%. In 54 patients with mediastinal tumors, definite histologic diagnosis could be obtained in 48 patients (88.9%). The sensitivity of ultrasound-guided biopsy for the diagnosis of malignancy in these 48 mediastinal tumors was 97.1%, with an accuracy of 97.9%. Three patients had complications with minimal pneumothorax and one with mild hemoptysis. We conclude that percutaneous transthoracic core biopsy with Tru-Cut needle under ultrasound guidance is a safe and sensitive way to obtain specimens for accurate histologic diagnosis of thoracic tumors. The diagnostic yield is high, and the technique, relatively simple, can also be used for outpatients.

Efficacy and safety of coaxial transthoracic fine-needle biopsy were evaluated in 54 patients with a history of malignant lymphoma and new chest lesions. Twenty-one patients had recurrent lymphoma. Correct diagnosis was made in 17 of the 21 patients (81%) after one biopsy. The sensitivity increased to 95% with repeat needle biopsy in three patients. Immunophenotyping (determining phenotype by means of immunologic examination) was essential for a definitive diagnosis of lymphoma in three patients. Non-lymphomatous malignancies were correctly diagnosed in 14 patients. An infectious organism was identified in 11 of 19 patients (58%) with benign lesions. Pneumothorax occurred in eight patients (15%), necessitating placement of a chest tube in two (4%). Mild hemoptysis was observed in four patients (7%). The authors conclude that coaxial transthoracic fine-needle biopsy in patients with a history of lymphoma is safe and accurate. The use of large cutting needles or surgical biopsy can be restricted to patients with false-negative findings at percutaneous biopsy and to patients in whom histologic transformation of lymphoma is suspected.

197 patients with either malignant (No. 175) or infections (No. 22) chest coin lesions had lung aspirations using fine-needles, 18 to 22 gauge. All the patients previously had flexible fiberoptic bronchoscopy with negative results. A positive diagnosis of malignancy was established in 138 (70%), with identification of cell type in 51 (37%), and of infectious disease in 11 (50%). The procedure's sensitivity for malignant lesions was 79.3% and the specificity was 96.5%. Complications were minimal (hemoptysis and pneumothorax), although some patients had COPD and hypoxemia.

During the 2 years of 1987 and 1988, 74 patients with suspected malignant lung lesions underwent fine needle aspiration biopsy at the Bradford Royal Infirmary. Using a 20Fr needle, sufficient specimen (smear and clot) was obtained in 70 (95%) patients for histological examination. The indications for the procedure were: failure to make a diagnosis at bronchoscopy and bronchial lavage in 32 (43%) patients, peripherally located lesion in 28 (38%) patients, poor anaesthetic risk in 20 (27%) patients, negative bronchoscopy and mediastinostomy in five (7%) patients and three (4%) patients refused operative intervention. There were no deaths and complications were few. Seven patients developed pneumothorax, three of whom required intercostal drainage. Transient haemorrhage as shown by haemoptysis occurred in one patient and one patient complained of pleuritic chest pain. Of the 60 patients with malignant disease eventually proven, 50 were diagnosed correctly. The overall sensitivity and specificity of the test were 81 and 100% respectively based on histological and/or clinical outcome of the lung lesion. The test was cost-effective, diagnostic yield was high and complications were few. The use of fine needle aspiration biopsy as part of the management policy in peripheral lung lesions is realistic in a district general hospital.

A 53-year-old male with a intra-pulmonary suture abscess was admitted with recurrent hemoptysis. Five year before this admission, he had undergone a partial resection of the left upper lobe for pneumothorax using unabsorbable sutures (braided polyester). Chest CT showed tumor shadow in the left S1(+2) a on admission. Because of recurrent hemoptysis, left upper lobectomy was performed. Hemoptysis was due to the presence of a suture abscess. Pathological and clinical analysis of the intra-pulmonary suture abscess showed that it was caused not only by foreign body reaction but also transbronchial infection.

Lymphangioleiomyomatosis is a rare devastating disease affecting women mostly of child-bearing age. It presents with spontaneous pneumothorax, chylous effusions, hemoptysis and progressive breathlessness. Most patients die from respiratory failure within 10 years. There are no controlled studies on the efficacy of various treatment regimens. We report our experience with progesterone therapy in three patients. Two failed to respond, one died about 11 years after presentation and another after 5 1/2 years. The third patient has survived 11 years after onset of disease.

We studied the safety and efficacy of unguided transthoracic fine needle aspiration biopsy (FNAB) in peripheral lung lesions in an outpatient setting in 62 patients. The diagnostic yield of unguided aspiration was 67.7 per cent. Smaller lesions usually required guided FNAB. Specific tissue diagnosis was obtained in all cases aspirated successfully. Complications were seen in 7 patients (pneumothorax in 4 and haemoptysis in 3 patients). With careful patient selection, unguided FNAB can be an effective out-patient procedure for diagnosing lung lesion beyond the reach of the fiberoptic bronchoscope.

A cystic fibrosis (CF) clinic for adults was established in 1977. We have reviewed the data on 164 patients who attended between 1977 and 1989. Twenty four patients had died, 11 being over 20 years of age at the time of death. Of the 140 patients still alive, 61% were male and 53% were aged over 20 years. Only 55% were diagnosed by one year and 88% by ten years. Almost all patients had respiratory symptoms and sputum culture yielded pseudomonas species in 69%. Other respiratory problems included major haemoptysis and pneumothorax, each in 10%. We found a wide range of respiratory impairment among older patients. Among 33 patients aged over 23 years, the mean (+/-S.D.) percent predicted FEV1 and FVC were 53.3% (+/- 18%) and 71.4 (+/- 20%) respectively. Mean weight in this group was 92.5% (+/- 14) of predicted. Malabsorption occurred in most patients and meconium ileus equivalent occurred in 34%. Other complications were clinical hepatomegaly (16%), diabetes mellitus (9%) and arthropathy (20%). Most patients were taking continuous antibiotics by mouth (89%) and by nebuliser (48%), beta-2 agonists by inhaler (57%) and oral steroids (29%). Almost all were taking multivitamins, pancreatic replacement therapy and multiple nutritional supplements. The number of CF "bed days" grew 12 fold since 1979 and the mean stay in hospital was double the hospital mean. The economic impact was such that over 1/4 of the annual hospital antibiotic budget was expended on CF patients.
