There is no standard treatment for patients with advanced hepatocellular carcinoma (HCC). We developed a product containing stem cells differentiation stage factors (SCDSF) that inhibits tumor growth in vivo and in vitro. The aim of this open randomized study was to assess its efficacy in patients with HCC not suitable for resection, transplantation, ablation therapy, or arterial chemoembolization. A total of 179 consecutive patients were enrolled. We randomly assigned the patients to receive either SCDSF or only conservative treatment. Primary end points were tumor response and survival. Secondary end points were performance status and patient tolerance. Randomization was stopped at the second interim analysis (6 months) of the first 32 patients recruited when the inspection detected a significant difference in favor of treatment (p = 0.037). The responses to the therapy obtained in 154 additional patients confirmed previous results. Evaluation of survival showed a significant difference between the group of patients who responded to treatment versus the group with progression of disease (p < 0.001). Of the 23 treated patients with a performance status (PS) of 1, 19 changed to 0. The study indicated the efficacy of SCDSF treatment of the patients with intermediate-advanced HCC.

Objective: We described an impressive cluster of hepatitis C in a single family. Of nine members of the family, six-the mother and five daughters-were affected by chronic hepatitis, hepatitis C virus (HCV) genotype 1b, of which two were co-infected with hepatitis B virus (HBV). Sharing a non-disposable injection equipment for intramuscular medical care was the most likely route of contagion. Twenty years after the first observation, we performed a follow up of this family. Methods: The clinical history was updated, and the members of the family underwent a clinical evaluation, extensive liver laboratory tests, and whole serology for hepatitis C and B. Protein chain reaction for HCV RNA was performed when indicated. The eight spouses of the offspring and their eight children underwent the same evaluation. Results: The main findings of this study are the favourable outcome of the two members of the family mono-infected by HCV, treated with peginterferon and ribavirin (sustained response and free of liver disease), in contrast with the ominous outcome of the two members co-infected with HCV and HBV, who evolved to decompensated cirrhosis, with hepatocellular carcinoma in one case, ultimately leading to death. A further feature is the absence of transmission of HCV to the spouses and to the third generation of children of this family, consistent with the assumption that sexual and vertical transmission is unlikely. Conclusions: A thorough epidemiological investigation of the two first generations of this family, the study of their spouses and children, and the twenty years of follow up provided a strong presumption that the infection with HCV had occurred within this family through the promiscuous use of the same inadequately sterilized glass syringe for intramuscular therapies, as was a common practice during the fifties and sixties worldwide and still is in some part of the world.

We studied 177 patients with pneumonia admitted to an internal medicine department over a period of 3 years to determine the incidence of two emerging pathogens, Legionellapneumophilaand Mycoplasma pneumoniae. Clinical, radiological and laboratory tests were performed and included blood cultures, serology, gram staining and sputum cultures. L.pneumophila was the agent involved in 9 patients (5.1%) and M. pneumoniae in 12 (6.8%). These prevalences were about in the middle of the range of previously published figures. Legionella pneumonia is a rare illness, which even in the absence of suggestive clinical signs must be considered because of its possibly serious course and to allow appropriate therapeutic decisions to be made.
