[Recommendations about immunizations in patients with inborn errors of immunity].

Inborn errors of immunity (IEI) are a heterogeneous group of hereditary disorders that affect in number and/or function different components of the immune system, resulting in an increased risk and severity of infections, autoimmune diseases, allergic manifestations, autoinflammation and malignancy. Inactivated vaccines are generally safe in these patients, but may be ineffective in some cases, due to difference in immunogenicity. However, live viral and bacterial vaccines may lead to disease, with high morbidity and mortality, so it is essential a previous immunological work-out.

Asbestos exposure affects poly(ADP-ribose) polymerase-1 activity: role in asbestos-induced carcinogenesis.

Asbestos is known to induce malignant mesothelioma (MM) and other asbestos-related diseases. It is directly genotoxic by inducing DNA strand breaks and cytotoxic by promoting apoptosis in lung target cells. Poly(ADP-ribose) polymerase-1 (PARP1) is a nuclear zinc-finger protein with a function as a DNA damage sensor.

Relationship of job satisfaction, psychological distress and stress-related biological parameters among healthy nurses: a longitudinal study.

Objective: To examine the relationship between job satisfaction, psychological distress, psychosocial processes and stress-related biological factors, and to evaluate whether over time changes of work satisfaction could affect the immunological-inflammatory status of workers.

Methods: One hundred and one nurses were enrolled at the Clinic of Occupational Medicine, Polytechnic University of Marche, Ancona, Italy. Perceived job satisfaction, psychological distress, and social support were assessed every 4 mo over a 1-yr period using 4 self-reported questionnaires.

Assessment of biomarkers in asbestos-exposed workers as indicators of cancer risk.

Epidemiological studies have shown that mortality from malignant mesothelioma (MM) and lung cancer have increased with increasing cumulative exposure to asbestos. To investigate whether tumour-related biomarkers can contribute towards the evaluation of the carcinogenic risk in populations exposed to asbestos, the DNA adduct 8-hydroxy-2'-deoxyguanosine (80HdG), interleukine-6 (IL-6), platelet-derived growth factor (PDGF-BB), hepatocyte growth factor (HGF), basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGFbeta) and soluble mesothelin-related peptides (SMRPs) were analysed in a cohort of workers differently exposed to asbestos fibres at the workplace. To document biomarker levels in an unexposed population, 54 age-matched subjects were enrolled.

Gleason grading of prostate carcinoma in needle biopsies vs. radical prostatectomy specimens.

The Gleason grading system for prostatic carcinoma is the dominant method used around the world in research and in daily practice. It is based on glandular architecture. The grading system should be applied to all prostatic tissue samples, including needle core biopsies and radical prostatectomy specimens.

Urothelial changes induced by therapeutic procedures for bladder cancer. A review.

Topical and systemic therapeutic agents and treatment modalities, such as thiotepa and mitomycin C, cyclophosphamide, bacillus Calmette-Guerin, radiation therapy, photodynamic and laser therapy, and gene therapy, produce a host of changes in the bladder, some of them mimicking cancer. Pathologists must be aware that following these types of treatment, the clinical utility of urinary cytology is reduced.

Molecular mechanisms in prostate cancer. A review.

Genetic studies have provided remarkable clues to the causes of prostate cancer (PCa). For example, in addition to the expected role of androgens in facilitating the development of PCa, the possibility that infections might lead to prostate cancer has been raised with the identification of RNASEL and MSR1 as familial prostate cancer genes; that insight will profoundly affect future studies and may ultimately lead to new approaches to the prevention of prostate cancer. The identification of key molecular alterations in prostate cancer cells implicates carcinogen defenses, including GSTP1, growth factor signaling pathways (such as NKX3.
