RESUMO

Hereditary hemorrhagic telangiectasia(Osler-Rendu-Weber Syndrome) is characterized by telangiectasia of the skin and mucous membranes and intermittent bleeding from vascular abnormalities. About 20% of patients with this is syndrome have pulmonary arteriovenous fistulas. Pulmonary arteriovenous fistula is uncommon malformation which has an abnormal connection between the pulmonary capillary bed, in which venous blind in the pulmonary artery is shunted through the fistula into the pulmonary vein without exposure to alveolar oxygen and result in unoxygenated, desaturated systemic arterial blood, polycythemia, cyanosis and clubbing. Death often results from cerebral abscess and rupture of the malformation with massive hemorrhage. Therapeutic intervention is recommended for all symptomatic patients because of the risk of those serious complications. Treatment options include surgery and transcatheter obliteration with steel coils or detachable balloons. Therapeutic embolization has the advantages that multiple bilateral pulmonary arteriovenous fistulas can be occluded and also that the procedure can be repeated if necessary. Recently we experienced a case of the multiple bilateral pulmonary arteriovenous fistulas associated with telangiectatic change of hepatic artery and multiple angiodysplasia on the gastric mucosa in 41 years old female patient who had mild dyspnea of exertion(NYHA class II), clubbing finger, severe iron deficiency anemia. She was treated with embolization technique using steel coils and iron replacement. After the therapeutic embolization, significant improvement of dyspnea of exertion with disappearance of multiple pulmonary nodule on follow-up simple chest x-ray was noted. During the subsequent six months follow-up period, she bad the improvement of symptoms arid iron deficiency anemia.

RESUMO

BACKGROUND: Various combinations of treatment modalities have been reported in stage III non-small cell lung cancer (NSCLC), however, the standard treatment modality has not established yet. Recently, the efficacy of concurrent chemotherapy and radiation therapy has been reported in locally advanced lung cancer. We evaluate the response rate, toxicity, arid survival of concurrent chemotherapy with etoposide and cisplatin(EP) arid radiation therapy for unresectable stage III NSCLC. METHODS: Between October 1995 and December 1996, 32 patients with histologically proven unresectable stage III NSCLC without, malignant pleural effusion were entered into this study. Twenty-nine patients were eligible for the response, survival, and toxicity analysis. Induction was two cycles of chemotherapy with etoposide arid cisplatin plus concurrent chest RT to 4500cGy. Resection was attempted if the clinical response offered surgical resectability. Boost radiation therapy upto 5940cGy and one cycle of EP were performed if the disease were stable or responsive but still unresectable. RESULTS: Of 29 eligible patients, 22(75.9%) showed partial response(PR). The progression free interval was 6.3months(range 1.1 to 19.5months). Surgical resection was performed in one patient The median survival was l2.1months and one-year survival rate was 50.6%. The major toxicity was leukopenia(> or = grade 3,46%) Thrombocytopenia over grade 3 was found in 1%. Radiation pneumonitis occurred in 13 patients(46%). CONCLUSION: Concurrent chemotherapy(EP) pins radiotherapy was effective and tolerable in the treatment of unresectable stage III NSCLC.

RESUMO

Development of diffuse pulmonary infiltrates in patients receiving chemotherapy is a major diagnostic challenge. Diffuse pulmonary infiltrates may be due to infection, pulmonary hemorrhage, pulmonary edema or drug-induced lung injury. Among these, pulmonary toxicity caused by antineoplastic agent is being recognized more frequently. Cyclophosphamide, an alkylating cytotoxic drug, is used widely in the treatment of malignancies including lymphoma. The incidence of pulmonary toxicity is probably less than 1 percent, and its relation with total dosages and schedule of the drug is not yet defined. The typical pictures of cyclophosphamide-induced pulmonary toxicity are non-productive cough, dyspnea, fever, hypoxemia with respiratory alkalosis and interstitial pneumonitis. However, relatively infrequent pulmonary toxicity of cyclophosphamide and frequent development of infectious pulmonary infiltrate in the patients treated with chemotherapy may hamper the early diagnosis of cyclophosphamide toxicity. Interstitial pattern and unresponsiveness to antibiotics of the pneumonitis might be the clues of suspicion. The best ways to treat the patients with cyclophosphamide toxicity are early diagnosis, discontinuation of the drug and early corticosteroid trial, although usefulness of steroid has not been firmly established. Recently, we experienced three cases of interstitial pneumonitis developing during cyclophosphamide-containing chemotherapy for non-Hodgkin's lymphoma in the absence of neutropenia or thrombocytopenia. Early use of corticosteroid in later two cases could resolve the pulmonary complication completely, whereas the pneumonitis failed to improve in spite of the massive use of multiple antibiotics in the first case.

RESUMO

Placement of the self-expandable metallic stents for palliative treatment of malignant esophagogastric strictures has been thought to be easy, fast and effective method than conventional methods (bypass procedures, radiation therapy, laser treatment, esophageal intubation, etc.). The expandable metallic stent tubes were found to overcome some of the limitations of nonexpandable conventional tubes. Their implantation is better tolerated and safer than that of nonexpandable tubes, because the risks of migration and perforation are lower.On our knowledge, there has been no report of pyloric obstruction after this metallic stent insertion.We hereby report a case of pyloric obstruction caused by a migrated self-expandable metallic stent for palliative treatment of malignant esophageal stricture.
