Mediastinitis due to cryptococcal infection: a new clinical entity in the HAART era.

Objectives: Highly active antiretroviral therapy (HAART) produces a rapid decline in plasma HIV-1 RNA levels with concomitant immune reconstitution. Probably due to the enhanced immune function, shortly after starting HAART, some latent opportunistic infections precipitated. The aim of this study was to illustrate the results of a survey on Cryptococcus associated mediastinitis occurring after HAART introduction, carried out at a referral centre of Infectious Diseases in the north-east of Italy, between October 1999 and October 2000.

[Treatment of hot thyroid nodule with percutaneous ethanol injection: indications, complications, and prognostic factors].

Percutaneous ethanol injection (PEI) has recently been proposed as an alternative therapy for toxic thyroid adenomas, instead of conventional treatments (pharmacological, surgical and radiometabolic therapies). The aim of this study was to investigate efficacy, complications and prognostic factors of PEI treatment in a group of 74 patients, 14 men and 60 women, treated from May, 1991, to December, 1994. Twenty-seven patients had nontoxic (pre-toxic) nodules (normal T3 and T4 and undetectable TSH serum levels) and 47 toxic nodules (high serum levels of thyroid hormones).
