ABSTRACT

BACKGROUND AND AIM: Respiratory failure in SARS-CoV-2 patients is characterized by the presence of hypoxemia and hypocapnia without relevant dyspnea. To date, the use of respiratory parameters other than PaO2/FiO2 ratio to stratify the risk of worsening of these patients has not been sufficiently studied.  Aim of this work was to evaluate whether the ratio between partial pressure levels of carbon dioxide (PaCO2) and the fraction of inspired oxygen (FiO2) measured at emergency department (ED) admission is predictive of the clinical course of patients suffering from SARS-CoV-2 pneumonia. METHODS: We retrospectively studied 236 patients with SARS-CoV-2 pneumonia evaluated at the ED of the Perugia Hospital. The end-points were: in-hospital mortality, need for invasive mechanical ventilation (IMV) and length of in-hospital stay (LOS). Clinical, blood gas and laboratory data were collected at ED admission. RESULTS: Of the 236 patients 157 were male, the mean age was 64 ± 16. Thirtythree patients (14%) needed IMV, 49 died (21%). In the univariate analysis, the PaCO2/FiO2 ratio was inversely associated with the need for IMV (p <0.001), mortality (p <0.001) and LOS (p = 0.005). At the multivariate analysis the PaCO2/FiO2 ratio was found to be predictive of the need for IMV, independently from age, gender, number of comorbidities, neutrophils, lymphocytes, glomerular filtrate, d-dimer, LDH and CRP. CONCLUSIONS: the PaCO2/FiO2 ratio is predictive of the risk of respiratory failure worsening in patients with SARS-CoV-2 pneumonia, independently from other several confounding factors.

ABSTRACT

OBJECTIVE: To analyse paediatric exposures to pod and traditional laundry detergents in Italy and changes in exposure trends. METHODS: Analyses of a series of patients aged <5 years and exposed to laundry detergents between September 2010 and June 2015, identified by the National Poison Control in Milan. RESULTS: In comparison with patients exposed to traditional laundry detergents (n=1150), a higher proportion of those exposed to pods (n=1649) were managed in hospital (68% vs 42%), had clinical effects (75% vs 22%) and moderate/high severity outcomes (13% vs <1%). Exposure rates were stable over time for traditional detergents (average 0.65 cases/day), but an abrupt decline in major company pods was seen in December 2012, 4 months after the introduction of opaque outer packaging (from 1.03 to 0.36 cases/day and from 1.88 to 0.86 cases/million units sold). The odds of clinical effects was higher for exposure to pods than for traditional detergents (OR=10.8; 95% CI 9.0 to 12.9). Among patients exposed to pods, the odds of moderate/high severity outcomes was four times higher for children aged <1 years than for the other age groups (OR=3.9; 95% CI 2.2 to 7.0). Ten children exposed to laundry detergent pods had high severity outcomes while no children exposed to traditional laundry detergents developed high severity effects. CONCLUSIONS: The study confirms that exposure to laundry detergent pods is more dangerous than exposure to traditional detergents. In Italy, 4 months after the introduction of opaque outer packaging by a major company, product-specific exposure rates decreased sharply, suggesting that reducing visibility of laundry detergent pods may be an effective preventive measure. Further efforts are needed to improve safety.

ABSTRACT

OBJECTIVES: European legislation requires reporting from Member States on acute poisoning incidents involving pesticides. However, standard rules for data collection and reporting have not yet been set out. The new categorization system presented in this paper is aimed at enabling Member States to gather comparable data and provide standard reporting on pesticide poisoning exposures. MATERIALS AND METHODS: European Regulations providing separate official categorization of biocidal and plant protection pesticides, were used as a basis to build up a unified pesticide categorization and coding system. Data on selected pesticide exposures collected by Poison Control Centres in six EU countries were reviewed, categorized and reported according to the proposed system. RESULTS: The resulting pesticide categorization system has two dimensions. The first part identifies the main category of use, i.e. biocide/plant protection pesticide/unknown, and the secondary category of use, e.g. Rodenticides, Insecticides and acaricides. The second part of the system is organized into two levels: level one identifies chemical grouping, e.g. Coumarins, Pyrethrins/pyrethroids, while level two identifies the active compound by using its Chemical Abstract Service Registry Number. The system was used to provide a unified categorization to compare exposures to plant protection and biocidal Rodenticides and Pyrethrins/pyrethroids Insecticides and acaricides identified by six EU member states. CONCLUSION: The developed pesticide categorization system was successfully applied to data extracted from different databases and was able to make the required information comparable. The data reported filling in common templates containing a pre-ordinate list of active compounds categorized according the proposed system, highlighted different capabilities in data collection and recording, showing that some of the collaborating centres were not able to distinguish between main categories of pesticide products or provide information on active compounds. The results indicate that a special effort should be dedicated to support detailed data recording at national level. Providing common tools to systematically report to the EU Commission hazardous exposures to pesticides, as well as to other selected categories of products, could allow for data comparability between Member States and greatly improve post marketing surveillance and alerting systems in Europe.

ABSTRACT

PURPOSE: Methylergometrine maleate is an ergot alkaloid frequently used in obstetrics for prevention and treatment of post partum haemorrhage. Accidental administration of this medicine to newborns can cause severe effects and should be carefully prevented. The present paper is aimed at describing the main characteristics of cases accidentally exposed to this medicine in Italy before and after Novartis, the manufacturer of Methergin®, a widely used methylergometrine maleate-containing gynecological medication, decided to withdraw the drop preparation from the European market. METHODS: The study design is a case-series study. The database of the National Poison Control Centre of Milan was searched retrospectively (from 1 January 2005 to 31 December 2011) and prospectively (from 1 January 2012 to 31 December 2013) in order to provide a descriptive analysis of the main characteristics of cases unintentionally exposed to methylergometrine maleate and to document the impact of Novartis' decision. RESULTS: In the first period under study (2005-2011), a total of 642 cases of exposure to methylergometrine maleate were identified. Most of them were children aged <1 year (No. 483, 75%). Patients aged 1-2 and 3-5 years accounted for 13% (No. 85) and 9% (No. 56) of cases, respectively. Among children aged <1 year, about 76% (No. 368) were exposed during the first month of life, including 44% (No. 211) of cases exposed in the first week of life. The main cause of exposure was medication error (No. 432, 89%), mainly due to oral administration of methyltergometrine maleate in place of a paediatric preparation (No. 469, 97%). About 14% of these cases suffered clinical effects as a consequence of the exposure. Severity of poisoning was minor in 45 cases, moderate in 12, and severe in one case. The main cause of exposure among children aged 1-2 and 3-5 years was uncontrolled access to the medicine, accounting for 78% (No. 66) and 77% (No. 43) of cases, respectively. Some 9% (No. 8) of cases aged 1-2 years and 7% (No. 4) of those aged 3-5 years developed signs/symptoms possibly related to the exposure. For all of them, severity of clinical effects was low, but one case suffered moderate effects. Exposure to the medicine in drops was reported for 87% (No. 74) and 84% (No. 47) of cases aged 1-2 and 3-5 years, respectively. In 2012-2013 a total of 25 cases were observed. Among them, two patients were aged <1 year (8%). Both cases occurred in 2012 and were inadvertently administered the medicine in drops still available (present) in the home. Fourteen (56%) and 8 (32%) cases were aged 1-2 and 3-5 years, respectively. All of them were exposed to the tablet formulation following uncontrolled access to the medicine. CONCLUSIONS: The observations here reported indicate that having different formulations for methylergometrine maleate-containing products intended for the mother and paediatric medicines can successfully prevent medication error due to medicine exchange in the first months of life.

ABSTRACT

The relationship between arterial stiffness, measured as pulse wave velocity (PWV), and the left ventricle is confounded by the effects of blood pressure. We evaluated the relationship between carotid-femoral PWV and cardio-ankle vascular index (CAVI), a less pressure-dependent measurement of the stiffness constant (ß) of the aorta and the iliac, femoral and tibial arteries, and obtained prognostically relevant measurements of left ventricular structure and systolic function. CAVI, carotid-femoral PWV and echocardiographic left ventricular mass and systolic function were determined in 133 subjects with either hypertension or high-normal blood pressure (33% treated; 56 ± 16 years, blood pressure 145/89 ± 21/12 mm Hg). Carotid-femoral PWV exhibited a direct relationship with systolic and diastolic blood pressure (r = 0.33/0.26, P < 0.001/0.014), whereas CAVI demonstrated no such relationship (r = 0.12/-0.05, both P > 0.1). Both CAVI and PWV correlated significantly with left ventricular mass index (r = 0.31, P<0.001; r = 0.21, P = 0.014). Subjects with inappropriately high left ventricular masses for a given cardiac workload (n = 44) had higher CAVI values (9.1 ± 2.0 vs. 7.9 ± 1.6, P < 0.001), but not higher PWV values (8.5 ± 2.5 vs. 8.7 ± 2.4, P>0.1). In a multivariate regression model, CAVI was independently associated with inappropriate left ventricular mass (ß = 0.40, P < 0.001), along with body mass index. CAVI also demonstrated a negative relationship with left ventricular midwall fractional shortening (r = -0.41, P = 0.001) that was independent of age, sex, blood pressure and left ventricular mass in a multivariate analysis. In conclusion, a high CAVI is associated with inappropriately high left ventricular mass and low midwall systolic function. As a marker of arterial diastolic-to-systolic stiffening, CAVI may have a relationship with left ventricular structure and function that is independent of blood pressure levels.

ABSTRACT

Elevated nighttime blood pressure (BP) and a reduced day-night BP fall ("nondipping" condition) are strong predictors of cardiovascular complications, both in hypertension and in the general population. A reduced or inverted nocturnal BP fall might also be theoretically used to define the most appropriate timing for drug administration. In a systematic review of the available evidence, we show that bedtime dosing of antihypertensive medication reduces nocturnal BP and increases day-night BP fall more than standard morning dosing. The effects of such an approach on average 24-hour BP are more modest and less univocal, with a considerable between-center heterogeneity. Admittedly, the mechanisms underlying non-dipping condition have not been fully understood yet, and it is still a matter of debate whether restorating a dipping pattern may reduce the cardiovascular risk associated with non-dipping independently from the effects on 24-hour BP. Under this regard, evidence from a single trial strongly suggests that bedtime dosing of antihypertensive medications may greatly reduce cardiovascular morbidity in hypertensive patients. The provocative results of that trial deserve to be explored further in larger intervention trials.

ABSTRACT

Short-term blood pressure (BP) variability predicts cardiovascular complications in hypertension, but its association with large-artery stiffness is poorly understood and confounded by methodologic issues related to the assessment of BP variations over 24 hours. Carotid-femoral pulse wave velocity (cfPWV) and 24-hour ambulatory BP were measured in 911 untreated, nondiabetic patients with uncomplicated hypertension (learning population) and in 2089 mostly treated hypertensive patients (83% treated, 25% diabetics; test population). Short-term systolic BP (SBP) variability was calculated as the following: (1) SD of 24-hour, daytime, or nighttime SBP; (2) weighted SD of 24-hour SBP; and (3) average real variability (ARV), that is, the average of the absolute differences between consecutive SBP measurements over 24 hours. In the learning population, all of the measures of SBP variability showed a direct correlation with cfPWV (SD of 24-hour, daytime, and nighttime SBP, r=0.17/0.19/0.13; weighted SD of 24-hour SBP, r=0.21; ARV, r=0.26; all P<0.001). The relationship between cfPWV and ARV was stronger than that with 24-hour, daytime, or nighttime SBP (all P<0.05) and similar to that with weighted SD of 24-hour SBP. In the test population, ARV and weighted SD of 24-hour SBP had stronger relationships with cfPWV than SD of 24-hour, daytime, or nighttime SBP. In both populations, SBP variability indices independently predicted cfPWV along with age, 24-hour SBP, and other factors. We conclude that short-term variability of 24-hour SBP shows an independent, although moderate, relation to aortic stiffness in hypertension. This relationship is stronger with measures of BP variability focusing on short-term changes, such as ARV and weighted 24-hour SD.

ABSTRACT

BACKGROUND: Inflammatory rheumatic diseases have been associated with increased cardiovascular risk and arterial stiffness. Polymyalgia rheumatica (PMR), a disease which affects primarily older people, is characterised by a systemic inflammatory response but little is known about aortic involvement in PMR. A study was undertaken to investigate whether aortic stiffness is increased in PMR and whether it improves after steroid treatment. METHODS: Thirty-nine patients with PMR (age 72 ± 8 years, 44% men, blood pressure (BP) 134/75 ± 16/9 mm Hg) and 39 age-, sex- and BP-matched control subjects underwent aortic pulse wave velocity (PWV) determination. Aortic augmentation as a measure of the impact of the reflection wave on central haemodynamics was also measured and corrected for heart rate. Twenty-nine of the patients were re-examined after 4 weeks of treatment with prednisone at a dose of 15 mg/day. RESULTS: Aortic PWV was higher in patients with PMR than in control subjects (12.4 ± 4 vs 10.2 ± 2 m/s, p<0.01). Treatment was followed by a reduction in heart rate (from 78 ± 12 to 70 ± 10 beats/min, p<0.001) and no significant change in BP. Aortic PWV decreased after prednisone treatment (from 11.8 ± 3 to 10.5 ± 3 m/s, p=0.015), and the difference was independent of BP and heart rate changes. The change in aortic PWV had a direct correlation with percentage change in plasma C reactive protein (r=0.40, p=0.037). Treatment was also associated with a significant reduction in aortic augmentation index (from 34 ± 7% to 29 ± 8%, p=0.012). CONCLUSIONS: Polymyalgia rheumatica is associated with increased aortic stiffness which may improve upon reduction of systemic inflammation induced by treatment with glucocorticoids.

ABSTRACT

Objective To evaluate the impact of a television advertising campaign on the risk of oral ingestion of a topical non-prescription gynaecological preparation containing benzydamine hydrochloride. Design An interrupted time series design with data routinely collected. Setting A National Poison Control Centre. Participants 215 cases of hazardous exposure to the preparation under study occurred in Italy from January 2005 to December 2010. Primary and secondary outcome measures Mean daily rate of cases of exposure by gender in three different periods, that is, pre-advertisement period, before the advertisement was broadcast (from 1 January 2005 to 19 December 2009), advertisement period, when the advertisement was repeatedly launched (from 20 December 2009 to 27 February 2010), post-advertisement period (from 28 February 2010 to 6 March 2010); observed/expected ratios of cases, with expected cases based on data from the pre-advertisement period, adjusted for estimated variations in the number of users. Comparison of the distribution of the main characteristics of cases in the three different periods by means of Pearson's χ(2) test or Fisher's exact test. Results The adjusted observed/expected ratio of cases in women was 7.48 (95% CI 5.76 to 9.56) in the advertisement period and 2.97 (95% CI 2.24 to 3.85) in the post-advertisement period. Regarding the characteristics of cases, there was an increased proportion of cases of exposure due to confusion about the correct administration route in the advertisement and post-advertisement periods (81% and 55%, respectively, compared to 16% for the pre-advertisement period.) and of individuals with clinical effects (55%, 52% and 27%, respectively). Conclusions In Italy, an advertisement for a non-prescription medicine seems to have confused consumers regarding the administration route. This effect was observed even after the advertisement had stopped being broadcast. These results highlight the need for the monitoring of medication errors and adverse effects before, during and after advertising.

ABSTRACT

OBJECTIVE: Aortic stiffness, a prognostically adverse marker of arteriosclerosis, is critically dependent on blood pressure (BP). Office BP may not always reflect BP behaviour away from the medical environment, and it is uncertain whether office or out-of-office BP values are stronger determinants of arterial stiffness. METHODS: Twenty-four-hour BP and carotid-to-femoral pulse wave velocity (PWV)--a direct measure of aortic stiffness--were measured in 539 never-treated hypertensive patients and in 71 normotensive individuals. RESULTS: Sustained hypertensive patients had a higher age and heart-rate-adjusted aortic PWV than normotensive individuals (9.7 ± 2 vs. 8.5 ± 2 m/s, P<0.001), even after further adjustment for office mean pressure as a measure of distending pressure (P=0.018). The higher aortic PWV in white-coat hypertensive patients as compared with normotensive individuals (9.3 ± 2 vs. 8.5 ± 2 m/s, P=0.026) did not hold after adjustment for office mean pressure (P=0.16). To examine the independent effect of office BP on aortic PWV beyond the influence of 24-h BP, patients were classified according to the difference between observed and predicted office systolic BP (the latter determined by regressing 24-h BP on office BP). Despite having comparable 24-h BP values (131/82 vs. 131/84 mmHg), the patients with higher-than-predicted office BP had higher aortic PWV than those with lower-than-predicted office BP (10.1 ± 2 vs. 9.2 ± 2 m/s, P<0.001). Similarly, after regressing office BP on 24-h BP, the group with higher-than-predicted 24-h BP also had higher aortic PWV (9.9 ± 2 vs. 9.5 ± 2 m/s, P<0.05) despite having identical office BP (152/95 vs. 152/96 mmHg). In a multivariate regression model, both 24-h and office mean BP independently predicted aortic PWV. CONCLUSIONS: Both office and out-of-office BP are independent predictors of aortic PWV in hypertension. Elevated BP values over the 24 h are associated with increased isobaric aortic stiffness.

ABSTRACT

The present paper describes a case of shoe contact dermatitis from DMF identified by the Poison Control Centre of Milan (PCCM), Italy, in 2009. A 35 year old woman was affected by irritant reactions while wearing shoes contaminated with DMF. Exposure to these shoes was limited to a 8 hour period and was not repeated. In the following days the patient suffered feet blistering and swelling limited to the area in contact with shoe vamp. Topical application of cortisone did not prevent development of bullous eczema. After 20 days from exposure, the lesions were healed but the skin remained red, dry and very sensitive. Chemical analyses of shoes quantified an average concentration of DMF of 383 mg/kg. The patient refused to be patch tested. The observation here reported confirm that DMF should be considered a possible causal agent in shoe contact dermatitis. Documentation of cases exposed to this chemical provide a relevant support to characterize clinical manifestations and to identifying contaminated articles.

ABSTRACT

OBJECTIVE: To describe methanol poisoning exposures in Italy and to investigate a cluster of methanol-related deaths due to abuse occurred in Sicily among immigrants from East Europe. DESIGN: the human methanol exposures handled by the Poison Control Centre of Milan, the major national centre for toxicological advise active in Italy, were reviewed retrospectively (January 2004-September 2006) and prospectively (October 2006-October 2008). SETTING: For each case of managed human exposure, the Poison Control Centre of Milan uses a standard format to collect patient information, substance/exposure information, clinical effects, therapy, outcomes. The database arising from that procedure was searched for all cases exposed to methanol and/or reporting selected clinical signs (i.e., metabolic acidosis with ocular effects and/or central nervous system depression and/or respiratory depression). Each case was reviewed and classified according to standard criteria. MAIN OUTCOMES: Three commercial products containing more than 70% methanol available on the market in Sicily and associated with lethal exposures due to abuse among immigrants were identified. RESULTS: In the period under study, the Poison Control Centre of Milan examined 29 methanol poisoning exposures (none in 2004, 6 in 2005, 6 in 2006, 15 in 2007, and 2 in 2008). Among them, 17 occurred in Sicily, with a peak of 11 cases in 2007, and 12 in other regions. The patients included 16 men and 13 women with a median age of 49,5 years (range 1-81 years). Fifteen cases were immigrants from East Europe (14 Rumanian and one Polish). Eleven cases reported minor effects, two cases moderate effects, four cases major effects, and 12 cases died. Twelve cases were accidental exposures (5 occurred at work, 3 at home and 4 in other places), while 17 cases were intentional exposures (14 due to abuse, 2 to attempted suicide and 1 to misuse). Minor effects were reported in 11 cases, moderate effects in two cases, major effects in four cases and death in 12 cases. The most frequently reported clinical effects included: coma (13 cases), metabolic acidosis (10 cases), mydriasis (4 cases), visual loss (3 cases), gastric pyrosis (2 cases), constriction of the visual field (2 cases), and vertigo (2 cases). Blood methanol level was reported for 15 cases (< 50 mg/dL in 2 cases; 50-99 mg/dL in 2 cases; 100-499 mg/dL in 4 cases; >500 mg/dL in 1 case; positive, unknown value in 6 cases). All cases due to abuse (n. 14) and, among them, lethal (n. 12) occurred in Sicily and involved immigrants. On the other hand, all methanol poisonings occurring in the other Italian regions involved Italian citizens unintentionally exposed and with minor effects, except for one case of attempted suicide with consequent major effects. The investigations performed in Sicily lead to identifying three locally produced and marketed detergents containing more than 70% methanol, improperly labelled and packaged. Furthermore, a detergent for domestic use was identified containing 25-30% methanol without any labelling information. Two of the detergents containing more than 70% methanol were withdrawn from the market in November 2007, while the other, that was identified later, was withdrawn in July 2008. The detergent for domestic use, containing 25-30% methanol was withdrawn in December 2007. Starting from July 2008, no new cases of methanol poisonings were observed. CONCLUSION: The availability in Sicily of products containing high concentrations of methanol, improperly packaged and labelled, determined a generalised risk of accidental exposures and favoured voluptuary assumption of methanol among selected groups. The observations highlight the importance of a surveillance system of toxic exposures based on the information collected by the Poison Control Centres and its ability to provide timely identification of unexpected and dangerous events and to support preventive actions.

ABSTRACT

BACKGROUND: A positive association between maternal occupational exposure to pesticide and spontaneous abortion has been reported in some studies. Work in greenhouses may imply exposure of pregnant women to pesticides continuously and at elevated level. METHODS: A total of 717 women working in greenhouses provided information on 973 pregnancies, including 110 spontaneous abortions. These pregnancies were classified as exposed or not exposed according to maternal occupation, re-entry activities and application of pesticides in greenhouses during at least 1 month in the first trimester of pregnancy. The ORs for spontaneous abortion were estimated through a generalised estimate equations model for all orders of pregnancy together, and through a logistic regression model limited to first pregnancies. RESULTS: Increased risks of spontaneous abortion were found for maternal re-entry activities within 24 hr after pesticides were applied (all orders of pregnancy: OR 3.2, 95% CI 1.3-7.7; first pregnancies: OR 3.8, 95% CI 1.0-13.9) and for those who applied pesticides (all orders of pregnancy: OR 2.6, 95% CI 1.0-6.6; first pregnancies: OR 3.7, 95% CI 0.7-20,6) CONCLUSIONS: The observed results support the hypothesis of an association between maternal work in greenhouses and spontaneous abortion. The main limitations of the study are lack of information on the specific chemicals used and the small number of pregnancies heavily exposed to pesticides.

ABSTRACT

AIM: To determine the use of personal protective equipment (PPE) among pregnant greenhouse workers in Italy and to identify risk factors related to the non-use of appropriate preventive measures. METHODS: A structured questionnaire was administered by trained interviewers, to Italian female greenhouse workers regarding their use of PPE and the occurrence of adverse pregnancy outcomes in their first pregnancy. RESULTS: Two hundred and thirty-two workers participated. Although most pregnant women used at least one form of PPE while working, there were differences in PPE use in different social groups. Overall, the protection was inadequate in the south of Italy and among the less educated. Pregnant women performing the most dangerous jobs often did so without using PPE. Even the use of gloves was absent in 50% of pregnant women who during their pregnancy prepared and mixed pesticides, and among 38% of those who applied pesticides directly. CONCLUSIONS: The use of protective measures was inadequate in the south of Italy and among less educated women. The study indicates the need for urgent interventions aimed at improving PPE use during pregnancy.

ABSTRACT

Between 1 February and 31 March 2006, the Poison Control Centers (PPC) active in Lombardy collaborated with an integrated surveillance system carried out in Piedmont during the Olympic Games 2006. The collaborating PPC notified to the system 697 human cases of exposure occurred in Piedmont during the observation period. Among these cases, 70% were exposed accidentally, 40% were 6 years old or younger, and 45% reported at least a clinical effect. The agents more frequently reported were: cleaning substances (household) (110 cases), fumes/gases/vapors (63 cases, comprising 38 cases accidentally exposed to carbon monoxide), and sedative/hypnotics/antipsychotics (53 cases). Although very limited, the available observations focused the attention on specific hazards and were able to highlight the potential of a toxic exposure surveillance system based on the information reported by the Italian PPC.

ABSTRACT

The aim of the study was to evaluate the possible effect of maternal work in greenhouses, as characterised by potentially high exposure to pesticides, on female fertility. Nine hundred and ten women active in 34 greenhouse flower growing enterprises in 1998-2000, with at least one pregnancy, and aged less than 50 years were identified. Seven hundred and seventeen (79%) agreed to be interviewed and reported 1699 pregnancies, of which 713 had complete information on time to pregnancy and occupation. These pregnancies were classified as exposed or non-exposed according to the maternal occupation in greenhouses at the moment of conception and analysed using logistic regression and survival analysis methods. We found a slightly higher proportion of pregnancies with delayed conception (more than 6 months) in the exposed group. However, after adjustment for confounding variables, the estimated hazard ratio for reduced fertility among the exposed was not significantly different to that of the non-exposed pregnancies (HR=0.96, 95%CI: 0.81, 1.13). A significant reduction in fecundability was observed in older women and with a daily consumption of one or more alcoholic beverages or cups of tea.

ABSTRACT

In Italy several studies have examined the association between cancer and occupation in agricultural settings, focusing on exposure to pesticides. Most of the cohort studies evaluated cancer mortality in licensed pesticide users. Many case-control studies considered hematolymphopoietic malignancies, and the most recent studies observed increased risks for use of specific chemical classes of pesticides. Preliminary data on pesticide-related illnesses must be taken into account, and a national surveillance system should be implemented to identify areas at high risk and to promote exposure-control programs.

ABSTRACT

Aim of the present cohort study was to evaluate the mortality pattern among workers in a cigar and cigarette factory in Lucca, Italy. The study followed 2341 workers (1585 women and 756 men) registered in the company payrolls and employed for at least six months from 1 January 1960 through 1 January 1994. Follow-up was between the start of employment in the factory and 1 June 2002 (totally 74363,5 person-years). For both sexes, all-causes mortality was lower than expected (men: SMR= 0.8; CI95% 0.7-0.9; 158 deaths; women: SMR= 0.9; CI95% 0.8-1.0; 584 deaths) and no excess of mortality was reported for all malignant neoplasms. Among female workers, the frequency of deaths from pleural cancer was elevated at a statistically significant level (SMR= 6.0; CI95% 2.4-12.6; 5 deaths). One death for pleural cancer also occurred among men versus 0.4 expected. All women deceased from pleural cancer had been working in tobacco manufacturing for at least 30 years. The excess of pleural neoplasms reported in this study suggests the opportunity to evaluate the risk due to asbestos use in many manifacturing industries, especially where steam was used for extractive or warming purpose.

ABSTRACT

OBJECTIVE: Aim of the present study is to provide a preliminary description of agricultural pesticide-related poisonings in Italy. DESIGN: The study focuses on the cases with at least one sign or symptom due to exposure to agricultural pesticides occurred in 2000-2001 and referred to the Poison control centre of Milan, the Italian centre more frequently consulted nationwide. RESULTS: During the study period, 872 agricultural pesticide-related poisonings were identified. Most of the observed cases occurred in Sicily (n=199), Lombardy (n=100), Apulia (n=99), Veneto (n=75), Emilia-Romagna (n=67) and Campania (n=59). About 86% of the observed cases were unintentional and about 76% of them were men. Children aged 10 or less accounted for about 6% of the total. The poisonings occurred more frequently at home (about 38%) than at workplace (about 24%). The chemical classes of agents more frequently reported were: organophosphates (233 cases), copper and sulphur compounds (140 cases), carbamates (126 cases) and pyrethrins/pyrethroids (102 cases). The top six pesticides associated with poisonings were methomyl (97 cases), dimethoate (59 cases), copper sulfate (58 cases), glyphosate (53 cases), sulphur compounds other than copper sulfate (47 cases), and paraquat dichloride (41 cases). CONCLUSION: The data here presented provide an initial support to identify priorities for prevention in agricultural settings.

ABSTRACT

Our study evaluates the association between prostate cancer and exposure to pesticides in agricultural settings in Italy. The data were derived from a hospital-based multi-site case-control study carried out in 5 rural areas between 1990-92. In our study, 124 new cases of prostate cancer were ascertained and interviewed, along with 659 cancer controls. A team of agronomists assessed past exposure to pesticides by using a checklist of 100 chemical families and 217 compounds applied from 1950-85 in the areas considered. The association between prostate cancer and different occupational risk factors was measured by maximum likelihood estimation of the odds ratio, controlling for potential confounders. "Ever been employed in agriculture" was associated with a 40% increased risk (OR = 1.4, 95% CI = 0.9-2.0). Prostate cancer was also related positively to food and tobacco (OR= 2.1, 95% CI = 1.1-4.1), and chemical products (OR = 2.2, 95% CI = 0.7-7.2) industries. The analyses carried out to estimate the association between different types of pesticides and prostate cancer showed increased risks among farmers exposed to organochlorine insecticides and acaricides (OR = 2.5, 95% CI = 1.4-4.2), more specifically to the often contemporary used compounds DDT (OR = 2.1, 95% CI = 1.2-3.8), and dicofol (OR = 2.8, 95% CI = 1.5-5.0), whose effects could not be well separated.
