Il versamento pleurico tubercolare è una causa comune di ricovero dei pazienti nell’ospedale Mulago, specialmente tra i pazienti affetti da HIV. L’istologia e la coltura del tessuto pleurico per MTB, il gold standard, comportano una procedura invasiva che richiede competenze specifiche e richiede molto tempo. Abbiamo testato l’accuratezza diagnostica del Gene Xpert specifico per MTB di Cepheid, un test in tempo reale basato sulla PCR che utilizza il liquido pleurico, con l’obiettivo di ottenere un metodo più rapido, più facile da usare, accurato e meno invasivo nella diagnosi della tubercolosi pleurica nel nostro contesto. Questo test ha dimostrato di migliorare la diagnosi della tubercolosi polmonare con accuratezza e in meno di 2 ore. Piccoli studi pilota hanno riportato livelli variabili di accuratezza di questo test nella diagnosi della tubercolosi pleurica. Tuttavia, uno studio sudafricano condotto da Sven et al. nel 2011 ha dimostrato una sensibilità del 25% e una specificità del 100% su 20 campioni di pazienti con TB pleurica confermata. Obiettivi: Determinare l’accuratezza del test Gene Xpert specifico per la TB nella diagnosi della TB pleurica tra i pazienti adulti con sospetto versamento pleurico tubercolare che hanno frequentato il Servizio di Pneumologia dell’Ospedale Mulago durante il periodo di studio.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...
