Abstract
From November 2008 to July 2010 we made 8300 drug tests to verify the absence of drug addiction or drugs/psychotropic substances consumption. We found 101 positive subjects (1.2%) at the first screening test; for fifty-five of them (54.5% of positives) we obtain a confirmation at second level test (0.7% of total tests). Sixty percent of these were positive for cannabinoids, 18.1% for opiates, 12.7% for cocaine, 9.0% for methadone, 3.6% for ecstasy and nobody for amphetamines. We noticed a good correlation between screening and confirmation tests for cannabinoids, methadone and cocaine. The analysis of the population of positive subjects shows that it's almost entirely composed by males, Italians, middle aged, heavy smokers and generally overweight, in apparent good health (average blood tests, any reported illnesses, any disability or any contraindications/limitations in employment).

Abstract
AIM Several randomized trials on conservative surgery compared with mastectomy in early-stage breast cancer have validated this technique in terms of local and distant relapse and survival of patients. Standard conservative approach includes surgical removal of the cancer with adequate cancer-free margins, axillary dissection, postoperative breast irradiation and adjuvant treatments when required. METHODS From 1987 to 2003, 500 early stage breast carcinoma were treated on 494 patients with conservative surgery and postoperative radiotherapy. Surgery consisted in a wide tumorectomy, with intraoperative control of R0 margins. The total postoperative radiation dosage was 50 Gy on the whole breast, associated with a boost of 10 Gy on tumor bed (20 Gy in T2 neoplasms). Before 1997 node-positive patients were treated with axillary irradiation with 50 Gy. Postoperative chemotherapy and/or hormonal therapy were administered to patients according with node-involvement, age and menopausal status. AJCC-stage was T1N0 in 44%, T2N0 in 15%, T1N1 in 19% and T2N1 in 22% of the patients. RESULTS In a postoperative setting, we observed 9% of axillary seromas or hematomas and 7% of oedema of the arm. At a median follow-up of 150 months (range 48-248 months), actuarial local recurrence rates were 7% at 5 years and 14% at 10 years. The actuarial rates of distant metastases were 18% at 5 years and 33% at 10 years. Ten-year overall and disease-free survival rates were 81% and 60%, respectively. Cosmetic results were good/excellent in 80%, satisfactory in 10% and poor in 10% of patients. CONCLUSION Recurrence and survival rates in breast-conserving surgery are consistent with indexed literature on conservative treatment of early breast cancer. Women eligible for conservative treatment should be offered the choice of either wide tumorectomy or quadrantectomy with axillary lymph nodes removal and postoperative radiotherapy, or modified radical mastectomy.

Abstract
The regulation of the work activity of young people (younger and apprentices) evolved in Italy - as in the others industrialized countries - in the last century. In the 1967 was promulgated the Law 977 (Protection of children and adolescent at work), still in force. To start the work activity, young people must be older than fifteen years and need to have ended the compulsory school. The most recent laws extend to the student the worker's rights. Many studies are conducted on the populations of apprentices - a sort of "virgin" subjects respect to work hazards - with the aim of early identify the subjects susceptible to develop, in future, illness related to work. In particular, many studies show an increased percentage in sensitization to high weight proteins, present in many working process, during the apprenticeship period. The practical stage activity, mainly necessary in the technical schools, can hide various hazards for the health of young students. The student must be followed by two different tutors, tightly collaborating together, one of the school and the other of the company where the work activity is done. The health status of the student could be evaluated before starting an hazardous work.

Abstract
e15138 Background: Bevacizumab (BEV) has shown clinical activity in metastatic colorectal cancer patients (mCRC)and randomised phase III trials have demonstrated that this agent significantly improves overall and/or progression-free survival when added to first-line irinotecan based chemotherapy (CT) regimens. We evaluated the efficacy and safety of BEV plus FOLFIRI (irinotecan, 5- fluorouracil, and leucovorin) as first line treatment in 27 consecutive metastatic colorectal cancer cases, with the primary end point to calculate the median time to clinical response with this chemotherapeutic schedule. Methods: Between October 2007 and January 2008 we collected the data on 27 patients with mCRC treated with first line chemotherapy with BEV plus FOLFIRI. Elegibility criteria had to be: mCRC; no prior CT for metastatic disease; ECOG PS 0/1, adequate organ function; no CNS metastases. The treatment consisted of a minimum of six cycles of irinotecan plus infusional 5-FU/LV according to the classical FOLFIRI schedule; BEV (5mg/kg) was given on day 1 with CT and then every 2 weeks until disease progression. Safety and response were assessed at the time of first CT and every 4 weeks thereafter. Results: 27 pts were evaluable (male 18; median age 61 years (range 45–77), ECOG PS 0: 52%, PS 1: 48%. The sites of metastases were: liver (15 pts), lung (5 pts), liver and lung (5 pts), peritoneal wall (2 pts).Median follow-up was 18 weeks. Two patients had complete response(CR) and 13 pts partial response (PR), with an overall response rate of 57.7%. Five patients had stable disease and 6 patients showed progressive disease. A clinical benefit was demonstrated in 77 % of pts. We observed a median time to clinical response of 11 weeks, evaluated with tumor markers and with CT/NMR/US examinations. A grade 3 or 4 neutropenia was detected in 39% of pts and grade 2 or 3 hypertension in 9%. We did’nt observe cases of thrombosis, bleeding and gastrointestinal perforation, sometimes related to the use of BEV. Conclusions: In this little experience the efficacy and safety of BEV associated with FOLFIRI schedule, a first line therapy in mCRC,is consistent with results from other previous studies, showing moreover a short time to clinical response with this association. No significant financial relationships to disclose.

Abstract
This study was designed to assess the efficacy and tolerability of MAS065D (Xclair) compared to a vehicle control in the management of radiation dermatitis in patients receiving radiotherapy for breast cancer. Twenty patients were randomized blindly to use the two study substances, three times daily, on separate sections of irradiated skin throughout the duration of radiotherapy and for two weeks afterwards. Patients were monitored before therapy, weekly during therapy, and for 2 weeks after radiotherapy was completed. Skin appearance according to National Cancer Institute (NCI) toxicity criteria, erythema rating, transepidermal water loss (TEWL), skin hydration, patients' view of itch, pain, acceptance, and view of each cream and adverse events, were monitored; at the final visit patients and investigators expressed their preference for one of the creams. MAS065D showed statistically significant superiority in the outcomes of NCI grading for radiation dermatitis and erythema. Patients' and investigators' preferences for one of the study substances were statistically in favor of MAS065D. Very few patients recorded nonzero itch and pain scales, so no significant differences emerged between the two groups. It was concluded that MAS065D can provide an effective option for managing radiation dermatitis although further studies are needed to assess its effect on pain and itch.

Abstract
The purpose of this work is to introduce a new treatment approach and technique for partial breast irradiation in only one session to patients in prone position by using a dedicated positioning device. The patients were treated on a home-made treatment table top that allows the breast to hang down. A particular immobilization system was introduced in order to assure the reproducibility of patient positioning between the CT acquisition session and the treatment session. The clinical target volume (CTV) was outlined according to surgical clips position and/or tumor location on preoperative mammography. Because of negligible movement due to respiration, only an additional margin of 3 mm was added to obtain the planning target volume (PTV). Based on radiobiological calculations, a dose of 21 Gy was prescribed to PTV. The tumor bed was treated with 3D-CRT technique by using 5 fields and rotating the table while the gantry was approximately 90 or 270 degrees. Thirty patients were enrolled for this study chosen in conformity to an approved clinical protocol. The average percentage of PTV volume enclosed in the 90% and 95% of prescribed dose were 99.9 and 98.6% respectively, while only 3.4% of PTV volume received more than 105% of prescribed dose. Dose to 3% of skin volume was, on average, 15.2 Gy. In 97% of patients, less than 50% of the ipsilateral breast received a dose greater than half the prescribed dose. Mean doses to lungs, heart and contralateral breast were negligible. With a median follow-up of 9 months, no important early toxicity was observed both for skin and breast tissue. The treatment of breast tumor bed in prone position in only one session by using the 3D-CRT is technically feasible and seems to be a promising alternative to other accelerated partial breast irradiation techniques.

Abstract
We want to evaluate the incidence of allergic problems in a population of catering students at the beginning and after 3 and 5 years of their course. We enrolled in the study 601 students of a professional catering school: 412 in the first year and 189 in the fifth years. We used two questionnaires to investigate respiratory problems and dermatological ones. All the subjects were also patch tested with 10 aptens. The incidence of reported symptoms of allergy was higher in fifth year than in first one. We can observe a rising in positive reaction between the two group of students to Balsam Perù, Nickel, Fragrance mix and Garlic. In particular we found an higher incidence of positive patch reaction in female population. On the contrary the rising in positive reaction to Garlic is higher in male. About two third of the subjects positive to garlic present a sensitization to diallyl disulphide. The rising of positive patch test reactions to Garlic and Balsam Perù should be caused by the contact with cooking spices. The higher incidence of allergic pathology between students during fifth year of school and students at first year is probably due to scholastic practical activity.

Abstract
The evolution of the modern anaesthesiologic technique aimed to detect more manageable and less toxic aesthetic gas, but adequately efficacy. This study considered the environmental and biological evaluation of the Careggi Hospital in Florence between 1991 and 2005. The pollution threshold of each aesthetic gas used (Nitrous oxide, Isoflurane and Sevoflurane) is reduced as time passed. The higher values about the pollution threshold have been found in the ophthalmology and in the otolaryngology operating room. We observed clinical and biological data of 74 health care workers (HCW). The anaesthetists and assistants were the more exposition. We didn't found any correlation between the exposure at gas and the clinical, and biological data. Some neurological and nonspecific symptoms (like head-ache and reduction of attention threshold) appear from the clinical informations; these symptoms suggest a possible effects on the HCW' health also for low pollution threshold.

Abstract
Respiratory diseases are frequent in tunnel construction workers. A group of 144 subjects randomly selected from the population of 2516 workers engaged in the construction of the railway tunnel under the Appennine Mountains, from Bologna to Firenze was investigated. A group of 69 males comparable for age, living area and habits was studied as a control group. Assessment of air pollutants (NO, NO2, SO2, total dust, silica %) was carried out by means of fixed monitoring stations as well as personal monitors. All the subjects included in the study were examined with a standardised protocol which included physical examination, lung function tests (before and after shift work) and a questionnaire to college respiratory symptoms. Low concentrations of environmental pollutants were evidenced. Significantly lower values of FEV1 and PEF were determined in the worker group pared to controls. A significant decrease in respiratory parameters was shown after shift work. Variables capable of influencing the decrease in parameters include smoking habits, work activity, presence of cough and expectoration, period of the year (spirometries resulted worse in the winter time). Significantly lower values of FEV1 and PEF were evidenced in the workers compared to controls. In spite of the present low work environmental exposure conditions, some physiologic parameters appear altered in tunnel construction workers. This may depend on a variety of noxious agents present in the working environment.

Abstract
The aim of this study is the evaluation of exposure to airborne, high-level disinfectants to efficiently organize prevention of the risks due to the manipulation of these substances in the endoscopic units in medical facilities. In field and personal samples in the breathing zone of the workers were taken in 27 endoscopic units in a hospital during the replacement of high-level disinfectants in basins, tubes and lavaendoscopes. After a campaign of environmental monitoring of glutaraldehyde in nineteen endoscopic units (176 employees) of the hospital and considering the entity of glutaraldehyde problem, two substitutes, peracetic acid and electrolyzed acid water, have recently been introduced. The level of glutaraldehyde was higher than the TLV-Ceiling in 13 out of 19 working units, while the value of peracetic acid resulted higher than TLV-TWA in 1 out of 15. EAW has recently been used in two units and the chlorine environmental concentrations resulted lower than the sensibility limit of the method (<75 microg/m3). The results obtained during this study of measurements allowed to identify those operations which have the highest degree of risk for employees; this serves for taking suitable measures for prevention and individual protection as well as for evaluating current practices and decisional processes in the hospital.

Abstract
4642 Background: The magnitude of the benefit of adding adjuvant hormonal treatment to radiotherapy for locally advanced prostate cancer is still unclear. We performed a pooled-analysis of phase III trials, to quantify the eventual benefit in recurrence decrease. Methods: All prospective phase III trials were considered eligible. A pooled analysis was accomplished, and event-based relative risk ratios (RR) with 95% confidence interval (CI) were derived through both a fixed- (FEM) and a random-effect model (REM) approach. Significant differences in primary outcome (recurrence rate), and secondary outcomes (overall survival), were explored. Magnitude outcome measures were: absolute benefits and number of patients needed to treat (NNT) for 1 patient to benefit. Heterogeneity test was applied as well. Results: Six trials designed to look if hormonal treatment plus radiotherapy decreases recurrence rate (3,571 patients) were gathered. In the primary outcome, the combined approach significantly improves the recurrence rate when applying the FEM (RR 0.72, 95% CI 0.68, 0.77, p < 0.0001), with an absolute benefit of 10.7%. The NNT was 9 patients. Although significant heterogeneity was found (p = 0.00001), the benefit remains significant at the REM as well (RR 0.67, 95% CI 0.54, 0.82, p < 0.0001). Although significant at FEM (RR 0.93, 95% CI 0.86, 1.00, p = 0.039) but heterogeneous (p = 0.0007), the overall survival demonstrated a not-significant trend in favour of the combined strategy at REM (RR 0.90, 95% CI 0.75, 1.10, p = 0.263). Conclusions: Considered all the available phase III trials, the combination of adjuvant hormonal treatment with radiotherapy over standard exclusive radiotherapy significantly decreases the recurrence rate in patients affected by localized prostate cancer. The significant heterogeneity in the analysis underscores the existing difference in patient’ characteristics. No significant benefit in overall survival was found. No significant financial relationships to disclose.

Abstract
1581 Background: The use of cytotoxic drugs concurrent with RT represents a promising approach in the combined treatment of malignant gliomas. Gemcitabine (dFdCyd) is a drug widely explored for its potential radiomimetic activity in different tumors. The present study was aimed to evaluate the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of weekly prolonged dFdCyd infusion, administered in combination with RT as first line treatment, in adult pts affected by supratentorial GBM. Methods: Within 6 weeks after surgery, in the presence of measurable residual disease and KPS >70, pts were treated with fractionated RT at a dose of 2.0 Gy/daily fractions, 5 days a week (global dose 60 Gy). From 24 to 72 hours before the first RT application, and afterwards once weekly, pts received concurrent dFdCyd, at fixed dose rate of 10 mg/m2/min, over a total period of six weeks. Planned dose levels of dFdCyd started from 200 mg/m2/weekly (level 1), with sequential steps of 25 mg/m2/w based on toxicity. Results: Ten pts were enrolled into the study: six were male, median age 55.2 years (range 44–75), with a median KPS at baseline of 85 (SD 9.71). The median time from diagnosis to the start of treatment was six weeks (range 4–7). The median RT duration was 6 weeks (range 4–7), all but one pt received the planned dose and all pts received concomitant CT. Four pts entered at Level 1; one pt was excluded from the study, due to rapid progressive disease during the treatment. Two of the three valuable pts presented a relevant neurological worsening; on this basis the dFdCyd dose was reduced to 175 mg/m2/w (Level -1). A total of six pts were entered at Level -1, and none of them reported DLT. No hematological grade 3–4 toxicity was reported. Grade 3 non-hematological toxicity was observed in one pt (transaminases increase). After a median follow-up of 13.4 months (range 3–24), the median progression-free survival was 8 months (CI 95% 1–18), and the median overall survival was 14 months (CI 95% 12–17). Conclusions: The recommended dose of prolonged infusion of dFdCyd concomitant with RT is 175 mg/m2/w. The observed activity has been considered interesting enough to support a phase II study of this concurrent CT-RT schedule as first line treatment in GBM. [Table: see text]
