RESUMO
Pneumomediastinum is a rare complication of a transbronchial lung biopsy. Common symptoms are chest pain, dyspnea, dysphagia, and specific electrocardiographic changes. We report a case of pneumomediastinum after a transbronchial lung biopsy. During the in-hospital stay, the symptoms and clinical picture rapidly improved without invasive treatment; therefore, the patient could be discharged after a few days. Approximately 1 month later, chest computed tomography was performed, which showed a complete resolution of the pneumomediastinum.
RESUMO
Co-infection with HBV and HCV seems to be associated with more severe liver disease in retrospective and cross-sectional studies in adults, but no data are available when co-infection is acquired in youth. The long-term outcome of infection acquired in youth was assessed in patients co-infected with HBV and HCV and in patients with HBV infection only. Twenty-seven patients with HBV and HCV co-infection and 27 patients infected with HBV only were enrolled. Seventy-six per cent of the patients were treated with alpha-interferon for 1 year. After a median follow-up of 23 years, the annual progression rate of fibrosis was 0.07 in patients co-infected with HBV and HCV, and in those infected with HBV it was 0.07 and 0.11 (P < 0.004) for HBe and anti-HBe-positive patients, respectively. In co-infected patients, the development of cirrhosis was observed in 2 (7.4%) and of hepatocellular carcinoma (HCC) in 1 (3.7%), while in those with HBV, cirrhosis appeared in one patient (3.7%). Alcohol intake (OR = 9.5 +/- 1.2; 95% CI = 6.6-13.9; P < 0.0001) was independently associated with cirrhosis and HCC. alpha-interferon showed no efficacy during treatment, but the treated group showed higher HCV RNA clearance during post-treatment follow-up. Co-infection with HBV and HCV and single HBV infection acquired in youth showed a low rate of progression to liver fibrosis, no liver failure, and low development of HCC during a median follow-up of 23 years (range 17-40).
