OBJECTIVES: To assess the usefulness of a technique for inserting hookwires guided by computed tomography to locate and resect pulmonary nodules by video-assisted thoracoscopy. To describe the procedure and its complications. PATIENTS AND METHODS: Nine pulmonary nodules were located in nine patients. All were = 2 cm in diameter, radiologically undefined and of unknown origin. Four patients had a history of cancer. The nodules were located using the needle/hookwire system (Kopans), guided by computed tomography and were resected by video-assisted thoracic surgery. RESULTS: The hookwire was placed correctly in 8 patients and incorrectly in 1. Thoracotomy was necessary for 1 patient. The histologic diagnosis was benign for all 9 nodules; 5 were hamartomas, 2 were necrotic or fibrotic nodules, 1 was a granuloma and 1 was an anthracotic node. Hospital stay ranged from 1 to 8 days (mean 3.3 days). CONCLUSION: The location of pulmonary nodes by hookwire and needle for later resection by video-assisted thoracoscopic surgery is a simple, safe way to facilitate removal in some cases, for diagnosis and treatment.

OBJECTIVE: In spite of improvements in imaging techniques, surgical procedures are often needed to diagnose and definitively treat mediastinal masses. The range of application of video-assisted thoracic surgery (VATS) in this context is still poorly defined. The present study describes and analyzes the experience of the Cooperative Group for Video-assisted Thoracoscopic Surgery of the Spanish Society of Pneumology and Thoracic Surgery (GCCVT-SEPAR), with the aim of determining the usefulness of the technique for treating mediastinal cysts and tumors. METHOD: For 2 years we gathered information prospectively on 1,573 consecutive VATS procedures in 17 hospitals. The data from 64 procedures performed for diagnosis and treatment of mediastinal cysts and tumors are analyzed. RESULTS: A definitive diagnosis was reached in all cases. Nineteen were malignant tumors and 45 were benign lesions. Twenty-five complete resections (39%) were performed: 6 pleuropericardial cysts, 4 bronchogenic cysts, 8 neurogenic tumors and other benign lesions. Radiologically poorly defined masses and those located in the anterior and median parts of the mediastinum were most often the object of diagnostic procedures, whereas cysts and well-defined solid lesions on the posterior mediastinum were usually the object of therapeutic interventions. Eleven percent of the cases required conversion to thoracotomy, mainly due to pleural adhesions. Four complications (6.3%) were recorded and no deaths occurred. The median hospital stay after surgery was 2.5 days; 7.8% of the procedures were performed on outpatients. CONCLUSIONS: VATS is performed on many mediastinal lesions in Spain. Cysts and benign tumors are selected for resection. Poorly defined and malignant lesions were diagnosed by biopsy. The experience reported demonstrates the efficacy and safety of this technique for selected cases.

OBJECTIVE: To investigate the occurrence and clinical correlation of the arg519-to-cys mutation in the type II procollagen gene in patients with osteoarthritis (OA). METHODS: Sixty-six subjects from 7 families with a strong family history of generalized OA and 13 patients with erosive OA were evaluated clinically and radiologically. Blood samples from 58 subjects in the familial OA group and from all 13 patients with erosive OA were obtained for DNA analysis. Exon 31 of COL2A1, which spans residue 519, was amplified by polymerase chain reaction. RESULTS: The arg519-to-cys mutation was detected in 2 of the 7 families with generalized OA. In these 2 families, the mutation was present in the 2 probands and in 19 other clinically affected family members, as well as in 3 (so-far) clinically unaffected family members (ages 25, 14, and 11 years). It was absent in 18 clinically unaffected members tested. The mutation was associated with a distinctive pattern of early-onset, aggressive, generalized OA with a mild spinal chondrodysplasia. Inheritance was autosomal dominant. No mutation was found in any of the patients with erosive OA. CONCLUSION: The arg519-to-cys mutation defines a new pathogenic factor in generalized OA with characteristic clinical and radiologic features. The demonstration of a mutation in 3 of 8 families with OA studied thus far suggests a significant incidence of genetically related clinical OA.

A case of a young woman with a 3-year history of mixed connective tissue disease who developed secondary pneumatosis intestinalis and pneumoperitoneum and died shortly after of rapidly progressive disease is reported. The pathogenesis, treatment and prognosis of this unusual complication in mixed connective tissue disease are discussed.

A retrospective study over an eight-year period of 33 episodes of leg ulceration in 26 patients with rheumatoid arthritis requiring inpatient management is reported. the aetiology of the ulcers was found to be multifactorial. The most common factors were venous insufficiency (45.5%), trauma or pressure (45.5%) and arterial insufficiency (36.4%). Vasculitis (18.2%) and Felty's syndrome (12.1%) were less frequent causes, and pyoderma gangrenosum was rare. Most patients had seropositive erosive disease with high rheumatoid factor titres and significant functional impairment; over half were on maintenance corticosteroids. Colonisation of the ulcers by organisms, predominantly Staphylococcus aureus, was common (69.7%). Skin grafting was required in 63.3%, but the rate of complete take was only 42.9% despite multiple attempts. Hospitalisation was prolonged (mean 47.9 days) and the recurrence rate requiring further hospitalisation was 26.9%. The diagnosis of vasculitis and the limited role of biopsy in establishing its presence are discussed.
