Spontaneous Cirrhosis Regression in an IFN-beta-induced AIH-like Syndrome Following Drug Withdrawal: Art of Facts or Artifacts?

Autoimmune hepatitis (AIH) is a disease of unknown aetiology with drug-induced AIH being the most complex and not fully understood type. We present the case of a 57-year-old female patient with acute icteric hepatitis after interferon-beta-1b (IFNβ-1b) administration for multiple sclerosis (MS). Based on liver autoimmune serology, histology and appropriate exclusion of other liver diseases, a diagnosis of AIH-related cirrhosis was established. Following discontinuation of IFNβ-1b, a complete resolution of biochemical activity indices was observed and the patient remained untreated on her own decision. However, 3 years later, after a course of intravenous methylprednisolone for MS, a new acute transaminase flare was recorded which subsided again spontaneously after 3 weeks. Liver biopsy and elastography showed significant fibrosis regression (F2 fibrosis). To our knowledge, this is the first report showing spontaneous cirrhosis regression in an IFNβ-1b-induced AIH-like syndrome following drug withdrawal, suggesting that cirrhosis might be reversible if the offending fibrogenic stimulus is withdrawn.

Metallurgia del piombo e siderurgia nel sito protostorico di Brunku ’e s’Omu (Sardegna centro-occidentale): inquadramento funzionale dei manufatti e ricostruzione dei processi produttivi

The archaeological excavations carried out in 2013 in the hut n. 16 of the protohistoric settlement of Brunku ’e s’Omu (central-western Sardinia) returned some metal products. The morpho-metric and functional study of these artifacts al-lowed the identification of two mending strips and other remains related to Bronze Age (late II millennium BC) ceramic vessels reparing. Some uncertainly dated slags and metal fragments were also identified. Visual examination and archaeometric investigation carried out by means of portable energy dispersive X-ray fluores-cence spectrometry (pXRF) were performed on these metals. The analyses were able to relate some remains to iron manufacturing and highlighted the lead composition of the other ones. The chosen approach further clarified some as-pects of nuragic metallurgists’ behaviour in selecting and processing metalliferous geo-materials.

Preliminary Notes on Two Seasons of Research at Oplontis B (2014-2015)

The complex known as Oplontis B lies in the shadow of Vesuvius, about 3 kilometers west of Pompeii and 300 meters from the well-known Villa A. Since its first excavation and reconstruction in the 1970s and 1980s, Oplontis B has languished in abandonment ―virtually unstudied. The Oplontis Project, led by John Clarke and Michael Thomas, began investigating the site in 2012 after completing its work on Villa A. The documentation of the complex is a primary task. In the past few years members of the Project team have cataloged the previously excavated materials, recording over 1200 wine amphorae as well as a variety of other artifacts. At the same time, Marcus Abbott has laser-scanned the building to produce a detailed plan of the site. The excavations have similar aims: to record the 79 CE level of the complex and to investigate its development. This paper discusses the preliminary results of the last two seasons of excavations and cataloging efforts which build on our previous work conducted in 2012 and 2013.
