The illegal use of glucocorticoids (GCs) as growth-promoters (GPs) is prohibited in farm animals in the European Union because the strong pharmacological activity of most synthetic GCs produces residues that are dangerous for human consumption. Among the alternative methods proposed to increase the efficacy of official controls, histology was the technique of choice in Italy on account of its high performance level. The aim of this study was to evaluate the reliability of immunohistochemistry (IHC) using anti-cleaved-Lamin A antibody to enhance the performance of the histological test applied to GC-related microscopic changes in the thymus.

Glucocorticoids, used in a wide range of pathologies thank to their therapeutical properties, are also illegally used as growth-promoters in animal breeding even if the European Union regulates their use to protect consumers' health from the adverse effects of residues in food. The first aim of the study was to establish the applicability of two histological parameters - atrophy and cortex-medulla ratio - to detect glucocorticoids misuse in calves. The second aim was to concurrently test the potentiality of both parameters to discriminate between treated and untreated animals.

Under current European Union legislation the use of anabolic steroids in food-producing livestock is banned because of their long-term adverse effects on human health. We examined the expression profile of the immunohistochemical marker progesterone receptor in veal calves' sex accessory glands following experimental administration of anabolic compounds. The aim was to confirm the accuracy of the immunohistochemical approach in the detection of the over-expression of the progesterone receptor induced by the administration of sexual steroids at low levels (17β-estradiol and nandrolone alone or in combination).

Sarcosporidiosis is caused by ingestion of contaminated raw or undercooked bovine meat and, although considered a minor zoonosis, it can represent a threath for immunocompromised people. Aim of this study was to determine the prevalence of spp. in bovine minced meat intended for raw consumption collected from butcher shops and retail stores in Turin's province (Piedmont region, Northwest Italy).

Aim: This observational study evaluated the behavior and outcome of cutaneous breast cancer metastasis treated with eribulin.

Patients & Methods: From November 2012 to January 2013, oncologists completed a database with patient, tumor and treatment characteristics from 14 Italian cancer centers. Skin lesions were assessed by Response Evaluation Criteria In Solid Tumors and cutaneous symptoms by present/absent criteria.

Invariant natural killer T (iNKT) cells are a distinct subset of human T cells, which expresses an invariant T cell receptor Vα24 Jα18 and recognizes glycolipid antigens in the context of CD1d molecules. iNKT cells exert pivotal regulatory roles in many immune responses, including antitumor immune responses. Alterations in iNKT cell frequency, phenotype, and activation state have been reported in cancer patients.

Mutations of three different genes, encoding β-amyloid precursor protein (APP), presenilin 1 and presenilin 2 are associated with familial Alzheimer's disease (AD). Recently, the APP mutation A673V has been identified that stands out from all the genetic defects previously reported in these three genes, since it causes the disease only in the homozygous state (Di Fede et al. in Science 323:1473-1477, 2009).

Objective: The present report updates the mortality cohort study of "Eternit" workers in Casale Monferrato, one of the major plant for the production of corrugated and plain sheets, tubes and high-pressure pipes in asbestos-cement in Italy active between 1907-1986.

Design: Retrospective cohort study.

Setting: The cohort included 3,443 blue-collar workers (2,663 men and 780 women) active between 1950 and 1986.

Malignant mesothelioma (MM) is a rare and aggressive tumor of the pleura. The most important causal factor for the development of MM is occupational exposure to asbestos. Different lines of evidence suggest a role of genetic background in MM development, as for other cancers.

Objective: Combination therapies of fluorouracil (FU) with irinotecan (CPT-11) and docetaxel plus cisplatin have been proven to be active in metastatic gastric cancer. In this paper, we present the results of a phase III trial in which these two combinations given sequentially were compared to mitomycin C (MMC) monochemotherapy in an adjuvant setting.

Methods: 169 patients with radically resected gastric cancer were randomized to receive CPT-11 (180 mg/m2 day 1), leucovorin (100 mg/m2 days 1-2), FU (400-600 mg/m2 days 1-2, q 14; for four cycles; FOLFIRI regimen), followed by docetaxel (85 mg/m2 day 1), cisplatin (75 mg/m2 day 1, q 21; for three cycles; arm A), or MMC (8 mg/m2 days 1-2 as 2-hour infusion, q 42; for four cycles; arm B).

Aims of this study were to evaluate the activity and toxicity of gemcitabine and cisplatin combination in malignant pleural mesothelioma (MPM). Patients with histologically proven MPM, < 75 years of age, Eastern Cooperative Oncology Group (ECOG) performance status (PS) < or = 2, and measurable MPM were eligible. Patients received gemcitabine 1250 mg/m intravenously on days 1 and 8 and cisplatin 75 mg/m on day 2, every 21 days, for a maximum of 6 cycles.

Objective: The study aimed at evaluating the activity and toxicity of gemcitabine monochemotherapy in a unselected series of elderly patients with advanced bladder cancer. The secondary objectives were to establish whether there is a correlation between treatment and Comprehensive Geriatric Assessment (CGA) and, in addition, to determine overall patient survival.

Methods: Treatment consisted of six courses of chemotherapy with gemcitabine at a dosage of 1,200 mg/m2 on days 1 and 8, every 21 days.
