Qualitative and quantitative alterations of mitochondrial DNA (mtDNA) in the skeletal muscle from two patients with cirrhosis and severe asthenia have been studied. The 4977 bp (mtDNA(4977)) and the 7436 bp (mtDNA(7436)) mtDNA deletions, as well as other mtDNA deletions, revealed by long extension PCR (LX-PCR), were found in the two patients, whereas the 10,422 bp (mtDNA(10,422)) mtDNA deletion was absent. Altogether, the qualitative alterations of mtDNA in cirrhotic patients with severe asthenia were comparable to those of age-matched healthy individuals. The mtDNA content, on the contrary, was substantially decreased in both patients with respect to control. Such mtDNA depletion might be explained by an increased, disease-related, oxidative damage to mtDNA, which probably affects the replication of the mitochondrial genome as already suggested in other oxidative stress-associated diseases.

Vitamin B12 deficiency is a potentially severe condition with clinical manifestations ranging from nonspecific symptoms, such as asthenia and glossitis, to severe hematological problems, including pancytopenia and megaloblastic anemia. One of the rare phenomena associated with this condition is pseudo-thrombotic microangiopathy (pseudo-TMA), which can mimic diseases such as thrombotic thrombocytopenic purpura (TTP), leading to possible misdiagnosis and inappropriate treatment. In this article, we present the case of a 62-year-old man with a history of intravenous drug use, untreated hepatitis C, smoking, and alcoholism.

An enduring example of long-term safety, attainability, and versatility has been pentoxifylline (PTX). PTX is a phosphodiesterase inhibitor that modulates inflammatory mediators and affects most blood components and the blood vessels.

Introduction: In the literature, the data about the factors related to the choice of the setting at patient's first palliative care admission visit are scanty. In fact it seems that the choice between home or hospice care is mainly based on the opinions and needs of patients, families and physicians. This study aims to address the association between the clinical factors detected at the first palliative visit in advanced cancer patients and the choice of palliative care setting (i.
