Background: The recent literature suggests that the incidence and prevalence of myasthenia gravis (MG) are changing. We performed a population-based study of MG in the province of Trentino (524,826 inhabitants) and compared the results with those collected 20 years ago. Methods: Multiple sources of information (discharge diagnosis, antibody tests and anticholinesterase drugs) were analyzed. Incidence was calculated from 2005 to 2009. Prevalence was calculated on December 31, 2009. Comparison was made with descriptive statistics for 1981-1990 for the identical region. Results: Incidence and prevalence greatly increased in comparison with 1981-1990 data. The prevalence rate increased from 82.9 (95% confidence interval, CI, 58.4-114.3) in 1990 to 129.6 (95% CI 100.6-164.3) per million population, whereas the average annual incidence increased from 7.4 (95% CI 5-10.4) per million person-years in 1981-1990 to 14.8 (95% CI 10.5-20.3) in 2005-2009. This increase was mainly due to male patients with late-onset MG. Conclusions: The study confirms the increase in incidence and prevalence of late-onset MG in the same region 20 years apart. So we should consider MG also as a disease of the elderly. © 2011 S. Karger AG, Basel. Source

Background: The optimal management of high-risk prostate cancer remains uncertain. In this study we assessed the safety and efficacy of a novel multimodal treatment paradigm for high-risk prostate cancer.Methods: This was a prospective phase II trial including 35 patients with newly diagnosed high-risk localized or locally advanced prostate cancer treated with high-dose intensity-modulated radiation therapy preceded or not by radical prostatectomy, concurrent intensified-dose docetaxel-based chemotherapy and long-term androgen deprivation therapy. Primary endpoint was acute and late toxicity evaluated with the Common Terminology Criteria for Adverse Events version 3.0. Secondary endpoint was biochemical and clinical recurrence-free survival explored with the Kaplan-Meier method.Results: Acute gastro-intestinal and genito-urinary toxicity was grade 2 in 23% and 20% of patients, and grade 3 in 9% and 3% of patients, respectively. Acute blood/bone marrow toxicity was grade 2 in 20% of patients. No acute grade ≥4 toxicity was observed. Late gastro-intestinal and genito-urinary toxicity was grade 2 in 9% of patients each. No late grade ≥3 toxicity was observed. Median follow-up was 63 months (interquartile range 31-79). Actuarial 5-year biochemical and clinical recurrence-free survival rate was 55% (95% confidence interval, 35-75%) and 70% (95% confidence interval, 52-88%), respectively.Conclusions: In our phase II trial testing a novel multimodal treatment paradigm for high-risk prostate cancer, toxicity was acceptably low and mid-term oncological outcome was good. This treatment paradigm, thus, may warrant further evaluation in phase III randomized trials. © 2014 Guttilla et al.; licensee BioMed Central Ltd. Source

The folate metabolism pathway has a crucial role in tumorigenesis as it supports numerous critical intracellular reactions, including DNA synthesis, repair, and methylation. Despite its importance, little is known about the influence of the folate pathway on gastrointestinal stromal tumour (GIST), a rare tumour with an incidence ranging between 6 and 19.6 cases per million worldwide. The importance of folate metabolism led us to investigate the influence of polymorphisms in the genes coding folate-metabolising enzymes on GIST susceptibility, tumour characteristics and clinical outcome. We investigated a panel of 13 polymorphisms in 8 genes in 60 cases and 153 controls. The TS 6-bp deletion allele (formerly rs34489327, delTInsTTAAAG) was associated with reduced risk of GIST (OR=0.20, 95% CI 0.05-0.67, P=0.0032). Selected polymorphisms in patients stratified by age, gender, and other main molecular and clinical characteristics showed that few genotypes may show a likely correlation. We also observed a significant association between the RFC AA/AG genotype and time to progression (HR=0.107, 95% CI 0.014-0.82; P=0.032). Furthermore, we observed a tendency towards an association between the SHMT1 variant allele (TT, rs1979277) and early death (HR=4.53, 95% CI 0.77-26.58, P=0.087). Aware of the strengths and limitations of the study, these results suggest that polymorphisms may modify the risk of GIST and clinical outcome, pointing to the necessity for further investigations with information on folate plasma levels and a larger study population. © 2015 Macmillan Publishers Limited.

Rationale: Acute effects of ozone on mortality have been extensively documented in clinical and epidemiological research. However, only a few studies have focused on subgroups of the population especially vulnerable to these effects. Objectives: To estimate the association between exposure to ozone and cause-specific mortality, and to evaluate whether individual sociodemographic characteristics or chronic conditions confer greater susceptibility to the adverse effects of ozone. Methods: A case-crossover analysis was conducted in 10 Italian cities. Data on mortality were collected for the period 2001 to 2005 (April - September) for 127,860 deceased subjects. Information was retrieved on cause of death, sociodemographic characteristics, chronic conditions from previous hospital admissions, and location of death. Daily ozone concentrations were collected from background fixed monitors. Measurements and Main Results: We estimated a 1.5% (95% confidence interval [CI], 0.9-2.1) increase in total mortality for a 10 μg/m3 increase in ozone (8-h, lag 0-5). The effect lasted several days for total, cardiac and respiratory mortality (lag 0-5), and it was delayed for cerebrovascular deaths (lag 3-5). In the subgroup analysis, the effect was more pronounced in people older than 85 years of age (3.5%; 95% CI, 2.4-4.6) than in 35- to 64-year-old subjects (0.8%; 95% CI,20.8 to 2.5), in women (2.2%; 95% CI, 1.4-3.1) than in men (0.8%; 95% CI, 20.1 to 1.8), and for out-of-hospital deaths (2.1%; 95% CI, 1.0-3.2), especially among patients with diabetes (5.5%; 95% CI, 1.4-9.8). Conclusions:Agreater vulnerability of elderly people and women was indicated; subjects who died at home and had diabetes emerged as especially affected. Source

Several epidemiological studies reported an association between antibiotic consumption in the first year of life and later asthma, but results are conflicting and affected by potential biases. We examined this controversial issue in a population-based birth cohort. Using administrative data, we identified 143,163 children born in 1995–2011 in Friuli-Venezia Giulia (Italy) (median follow-up 5.25 years, 927,350 person-years). Antibiotic prescriptions in the first year of life and subsequent treated asthma (defined as ≥2 anti-asthmatic drug prescriptions within a 12-month period) were retrieved from drug prescription records. We estimated incidence rate ratios (IRR) using Poisson regression models, adjusted for perinatal variables and for hospitalizations for infections in the first year of life. We identified 34,957 new-onset asthma cases. Antibiotic consumption in the first year of life increased the risk of new-onset asthma [IRR 1.51, 95 % confidence interval (CI) 1.48–1.54] with a dose–response relationship (p-trend <0.001). The risk was highest for asthma identified at 13–35 months of life (IRR 2.07, 95 % CI 2.00–2.14), but remained statistically significant for asthma identified at 36–71 months (IRR 1.17, 95 % CI 1.14–1.21) and at ≥72 months (IRR 1.15, 95 % CI 1.08–1.22). Antibiotics increased the risk of current asthma at ≥6 years (IRR 1.35, 95 % CI 1.30–1.41) and at ≥13 years of age (IRR 1.19, 95 % CI 1.08–1.33). Antibiotic exposure in infancy is associated with an increased risk of asthma up to adolescence. The association detected at older ages is not explained by reverse causation; however, confounding by respiratory infections not leading to hospital admission cannot be excluded. © 2015, Springer Science+Business Media Dordrecht.
