Isotopic evidence for age-related immigration to imperial Rome.

Oxygen stable isotope ratios (delta(18)O) have been determined in carbonate in paired first and third molar teeth from individuals (N = 61) who lived in the town of Portus Romae ("Portus") and who were buried in the necropolis of Isola Sacra (First to Third centuries AD) near Rome, Italy. We compare these analyses with data for deciduous teeth of modern Roman children. Approximately one-third of the archaeological sample has first molar (M1) values outside the modern range, implying a large rate of population turnover at that time, consistent with historical data. Delta (18)O(ap) values suggest that a group within the sample migrated to the area before the third molar (M3) crown had completely formed (i.e., between 10 and 17.5 years of age). This is the first quantitative assessment of population mobility in Classical antiquity. This study demonstrates that migration was not limited to predominantly single adult males, as suggested by historical sources, but rather a complex phenomenon involving families. We hypothesize that migrants most likely came from higher elevations to the East and North of Rome. One individual with a higher delta(18)O value may have come (as a child) from an area isotopically similar to North Africa.

Cytomegalovirus infection in day care centers in Rome, Italy: viral excretion in children and occupational risk among workers.

From nine day care centers in Rome, Italy, 253 children of middle to low socioeconomic classes were examined for cytomegalovirus (CMV) excretion in saliva. The overall excretion rate was 13%, with no marked differences between centers. Socioeconomic level, age of enrollment, chronological age, length of attendance, and number of siblings did not have any discernible influence on viral shedding. The most notable result is that during the second year of age, 100% of the excretors had been breast fed, but only 60% in the third year, indicating that maternal transmission is the most likely source of children's infection early in life. Serologic survey of 82 female workers in day care centers, 82 matched housewives, and 229 female students aged 14 to 18 years who were in training to care for children showed that at 14 years of age the CMV seropositivity rate is 85, which suggests that primary infection during childbearing age is an uncommon event in Rome.

A subject with abnormally short stature from Imperial Rome.

In spite of the rich iconographic and literary documentation from ancient sources, the skeletal evidence concerning individuals of abnormally short stature in the Greco-Roman world is scarce. The necropolis of Viale della Serenissima/Via Basiliano in Rome, mostly referable to the II century AD, recently yielded the skeleton of an individual characterized by proportionate short stature, gracile features suggesting female gender, and delayed epiphysial closure, associated with full maturation of the permanent dentition. These characteristics could be compatible with the phenotype associated with female gonadal dysgenesis. The skeletal individual described here, although poorly preserved, represents the first evidence of a paleopathologic condition affecting skeletal growth documented for the population of ancient Rome.

Bile duct injuries during laparoscopic cholecystectomy: a 1994-2001 audit on 13,718 operations in the area of Rome.

BACKGROUND: Bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC) still are reported with greater frequency than during open cholecystectomy (OC). METHODS: In 1999, a retrospective study evaluating the incidence of BDIs during LC in the area of Rome from 1994 to 1998 (group A) was performed. In addition, a prospective audit was started, ending in December 2001 (group B). RESULTS: In group A, 6,419 LCs were performed (222 were converted to OC; 3.4%). In group B, 7,299 LCs were performed (225 were converted to OC; 3.1%). Seventeen BDIs (0.26%) occurred in group A and 16 (0.22%) in group B. Overall, mortality and major morbidity rates were 12.1% and 30.3%, respectively, without significant differences between the two groups. CONCLUSIONS: The incidence and clinical relevance of BDIs during LC in the area of Rome appeared to be stable over the past 8 years and were not influenced by the use of a prospective audit, as compared with a retrospective survey.

Asbestos hazards in the city of Rome, Italy.

A review is made of asbestos as a health hazard, and attention is drawn to possible dangers due to exposure to asbestos in the city of Rome in and outside the work place. The exposure to asbestos of workers of the ATAC company (the public concern of urban passenger transport of Rome) is examined. This is particularly dangerous for workers who repair equipment with asbestos components, such as brake linings. Exposure to asbestos may also occur in inhabitants who live and work close to where asbestos fibres collect. The study evaluates the contamination of asbestos fibres in both work and urban environment among people directly or indirectly exposed to this pollutant.

Khat chewing spread to the Somali community in Rome.

The habit of chewing Khat (Catha edulis) to experience its euphorizing and psychostimulant effects has prevailed for centuries among the inhabitants of the Horn of Africa and the Arabian peninsula. In recent years, air transport has removed the major obstacle to the diffusion of Khat, its perishableness. Khat is now air-freighted to Europe and we were able to buy some in Rome. We report the results of interviews with 20 members of the Somali community in Rome, who had continued their habit of chewing Khat whilst abroad. They asserted that they gathered together whenever possible, but preferably at weekends, to chew moderate quantities of Khat (one bundle, about 400 g). The customary habit of drinking tea or other soft drinks containing methylxantines during Khat sessions was maintained and very few subjects admitted drinking alcohol. In this small study sample, Khat chewing still seems to be a social event, as it is in Somalia.

Epiphytic lichens as indicators of environmental quality in Rome.

A synthesis of the studies on lichen diversity carried out in Rome over the period 1982-2003 is presented. In this work, the Lichen Diversity (LD) method has been applied. Besides air pollution, the most important variable affecting the epiphytic lichen flora of Rome, currently updated to 102 taxa, is the influence of the Tyrrhenian Sea. Significant changes in the lichen flora have been noted over the past 20 years, with the lowest diversity now being found in the urban centre and in the eastern and southern sectors, while the "lichen desert" area has decreased in parallel with decreasing concentrations of CO, NO(x) and SO2.

Prevalence of Escherichia coli O157 in lambs at slaughter in Rome, central Italy.

A study on the prevalence of the faecal carriage of Escherichia coli O157 in lambs was performed in the major slaughterhouse in Rome, central Italy, during 2002. A total of 643 animals, consisting of 378 weaned and 265 suckling lambs, were assayed for the presence of E. coli O157. Five O157-agglutinating E. coli strains were isolated (0.8%, 95% CI 0.3-1.9). Only one was positive to PCR specific for the eae gene and produced verocytotoxin VT2, with a VTEC O157 overall prevalence of 0.2% (95% CI 0.0-1.0), whereas one strain possessed the eae gene only. All the other isolates were negative for the presence of all the virulence genes considered. The animals were either from local farms or imported from Eastern Europe. The results suggest an age-specific difference since the microorganism was isolated only from 0.3% (95% CI 0.0-1.7) of weaned lambs, while all samples from suckling lambs tested negative. From this study, the overall risk of human exposure to pathogenic E. coli O157 from lamb meat consumption derived from the major slaughterhouse in Rome can be considered reasonably low, particularly when suckling lamb meat is considered.

Skin diseases in immigrants seen as out-patients in the Institute of Dermatology of the University of Rome 'La Sapienza' from 1989 to 1994.

In the Institute of Dermatology of the University of Rome 'La Sapienza' (IDURLS) from 1989 to 1994, 2198 immigrants from countries outside the European Community were seen as out-patients. Their personal and pathological data were collected by a particular software 'Questio', set up together with colleagues of the Interdepartimental Center for Scientific Calculous (ICSC) of the University of Rome 'La Sapienza'. The number of patients has been increasing from 326 in 1989 to 436 in 1994. Most of the people were coming from Africa, but from 1989 to 1994 the number of patients from the regions of ex-Yugoslavia has been increasing. About one third of the immigrants were unemployed, whereas 40% of them had a job (worker or employee), and the remaining 20% was composed by students and housewives. Most immigrants (1474 patients) were 20-39-year-old. Their data were compared with those of a control group composed by 2100 Italian people of the same age and sex, seen as out-patients in IDURLS in the same period. The most frequent skin disorders observed in immigrants were skin infectious or parasitic diseases, above all scabies. Excluding people with scabies, both immigrants and Italian patients shared the same skin diseases typical of young adult people: many fungal infections, many contact dermatitis and very few skin malignant tumors.

Mortality among problem drug users in Rome: an 18-year follow-up study, 1980-97.

AIM: To analyse overall and cause-specific mortality among problem drug users (PDUs) attending treatment centres in Rome and to evaluate differences in mortality between genders. METHODS: A cohort of 11 432 PDUs entering treatment in Rome between 1980 and 1995 was enrolled and followed-up as of May 31, 1997. Directly standardized mortality rates and standardized mortality ratios (SMRs) and their 95% confidence intervals (95% CI) were calculated. RESULTS: The study population included mainly males (82%), heroin users (92%) and had a mean age of 26.6 (SD 5.9) at enrollment. At the end of the study period 1734 deaths were observed. Overall mortality rates began to increase in 1985-86 and decreased slightly afterwards. AIDS mortality peaked in 1991-92 (13.2/1000) and fell in the following years. A slight decrease in overdose mortality also occurred after 1989-90. Mortality for causes other than AIDS and overdose remained high and relatively steady for the whole study period. Women showed higher mortality rates for AIDS but lower mortality rates for overdose than males. Overall mortality risk among drug addicts was about 15 times higher compared to the general population of the same age among men, and 38 times higher among women. CONCLUSIONS: AIDS mortality among drug addicts began to decrease earlier than expected; the decrease was particularly significant in the period 1993-94 for both sexes. Afterwards a continuous but slight decrease was observed among males only. Even though overdose mortality has also decreased slightly in recent years, we still observe high mortality levels for both overdose and all other causes. These findings suggest that interventions directed specifically towards the reduction of baseline mortality are still needed.

Radiometric characterisation of more representative natural building materials in the province of Rome.

Natural building materials, characterised by middle-low-activity concentrations of primordial radionuclides ((40)K, (232)Th and (238)U series) are widely used in Italy. Since natural materials reflect the geological variability of their sites of origin, a systematic study was carried out in the province of Rome and the results are reported in this paper. In the present work, in order to evaluate average, minimum and maximum contents of primordial radionuclides, more representative lithologies outcropping on the territory of the province of Rome were identified and around 150 samples were collected. Also, these lithologies were characterised from a radioprotection point of view, by means of the evaluation of the index, I, when they are used as building materials. The results confirm the high-primordial radionuclide content within some materials used in Latium (central Italy). Although the study was carried out in a limited area, the results confirm considerable variation in the primordial radionuclide content depending on the sites of origin.

Air pollution and myocardial infarction in Rome: a case-crossover analysis.

BACKGROUND: Daily air pollution is associated with increased hospital admissions for cardiovascular diseases, but there are few observations on the link with acute myocardial infarction. To evaluate the relation between various urban air pollutants (total suspended particulate, SO2, CO, NO2) and hospital admissions for acute myocardial infarction in Rome, Italy, we performed a case-crossover analysis and studied whether individual characteristics act as effect modifiers. METHODS: We studied 6531 subjects residing in Rome and hospitalized for a first episode of acute myocardial infarction (International Classification of Diseases, 9th edition: 410) from January 1995 to June 1997. The following individual information was available: sex, age, date of hospitalization, coexisting illnesses (hypertension, 25%; diabetes, 15%), and cardiac severity (conduction disorders, 6%; cardiac dysrhythmias, 20%; heart failure, 11%). Daily air pollution data were taken from 5 city monitors. We used a time-stratified case-crossover design; control days were the same day of the week as the myocardial infarction occurred, in other weeks of the month. RESULTS: Positive associations were found for total suspended particulate, NO2 and CO. The strongest and most consistent effect was found for total suspended particulate. The odds ratio (OR) associated with 10 micro g/m3 of total suspended particulate over the 0- to 2-day lag was 1.028 (95% confidence interval [CI] = 1.005-1.052). The association with total suspended particulate tended to be stronger among people older than 74 years of age (OR = 1.046; CI = 1.005-1.089), in the warm period of the year (OR = 1.046; CI = 1.008-1.087), and among subjects who had heart conduction disorders (OR = 1.080; CI = 0.987-1.181). CONCLUSIONS: The results suggest that air pollution increases the risk of myocardial infarction, especially during the warm season. There was a tendency for a stronger effect among the elderly and people with heart conduction disturbances.

Associations of area based deprivation status and individual educational attainment with incidence, treatment, and prognosis of first coronary event in Rome, Italy.

BACKGROUND: Socioeconomic gradients in the occurrence of myocardial infarction are well known, but few studies have examined socioeconomic disparities in post-infarction outcomes. The objective of this study was to explore relations of socioeconomic status with the incidence, treatment, and outcome of first coronary event in Rome, Italy, during the period 1998-2000, examining effect modification by gender. METHODS: Subjects were Rome residents aged 35-84 years who died from first acute coronary event before reaching the hospital (n=3470) or were hospitalised for first acute myocardial infarction (n=8467). Area based deprivation status and patients' educational attainment were the exposure variables. The outcomes were: incidence of coronary event; recanalisation at the index hospitalisation and fatality within 28 days of hospitalisation; cardiac readmissions and fatality between 28 days and one year of index hospitalisation. RESULTS: Incidence rates increased as area based deprivation status increased; the effect was stronger among women than among men (men RR=1.40, 95%CI:1.30, 1.50, women RR=1.78, 95%CI:1.60, 1.98, most compared with least deprived). Rates of recanalisation were significantly lower in the most deprived patients than in the least deprived (OR=0.77, 95%CI:0.59, 0.99) and in the less educated than in the highly educated (OR=0.73, 95%CI:0.58, 0.90). Associations of short term fatality with area based deprivation status and educational attainment were weak and inconsistent. However, neither deprivation status nor education was associated with one year outcomes. CONCLUSIONS: Area based deprivation status is strongly related to incidence of coronary events, and more so among women than among men. Deprivation status and educational attainment are weakly and inconsistently associated with short term fatality but seem not to influence one year prognosis of acute myocardial infarction. Deprived and less educated patients experience limited access to recanalisation procedures.

Malignant melanoma in Rome, Italy, 1970-9.

An epidemiological study was conducted in the city of Rome and the incidence of malignant melanoma was determined retrospectively for the years 1970-9. All patients had legal residence in Rome and a histological diagnosis of melanoma during that period; only cases of malignant melanoma of the skin (ICD 172, 8th revision) were considered. A total of 17 public and 82 private hospitals were involved in the study with 11 081 and 6127 hospital beds respectively. All the hospitals in the study had one of the following therapeutic and diagnostic facilities: internal medicine, dermatology, oncology, radiology, surgery, plastic surgery, histopathology. Analyses of incidence are based on 500 cases, 237 males and 263 females, collected in the period 1970-9. The data indicate a positive time trend in incidence; the average annual increase is 0.27 cases/year per 100 000. The data show that in a Mediterranean and Latin country such as Italy the incidence of melanoma presents the same ascending trend as that of other Caucasian countries, whether European or not, the slope of the curves is similar for both sexes. The distribution of the primary site for both sexes is closely parallel to that described for all Caucasian populations, the lower limbs being more affected in females and the trunk in males.

Coronary artery bypass graft surgery: socioeconomic inequalities in access and in 30 day mortality. A population-based study in Rome, Italy.

OBJECTIVES: To evaluate whether coronary artery bypass graft (CABG) surgery is equally provided among different socioeconomic status (SES) groups in accordance with need. To estimate the association between SES and mortality occurring 30 days after CABG surgery. DESIGN: Individual socioeconomic index assigned with respect to the characteristics of the census tract of residence (level I = highest SES; level IV = lowest SES). Comparison of age adjusted hospital admission rates of ischaemic heart disease (IHD) and CABG surgery among four SES groups. Retrospective cohort study of all patients who underwent CABG surgery during 1996-97. SETTING: Rome (2 685 890 inhabitants) and the seven cardiac surgery units in the city. PARTICIPANTS: All residents in Rome aged 35 years or more. A cohort of 1875 CABG patients aged 35 years or more. MAIN OUTCOME MEASURES: Age adjusted hospitalisation rates for CABG and IHD and rate of CABG per 100 IHD hospitalisations by SES group, taking level I as the reference group. Odds ratios of 30 day mortality after CABG surgery, adjusted for age, gender, illness severity at admission, and type of hospital where CABG was performed. RESULTS: People in the lowest SES level experienced an excess in the age adjusted IHD hospitalisation rates compared with the highest SES level (an excess of 57% among men, and of 94% among women), but the rate of CABG per 100 IHD hospitalisations was lower, among men, in the most socially disadvantaged level (8.9 CABG procedures per 100 IHD hospital admissions in level IV versus 14.1 in level I rate ratio= 0.63; 95% CI 0.44, 0.89). The most socially disadvantaged SES group experienced a higher risk of 30 day mortality after CABG surgery (8. 1%) than those in the highest SES group (4.8%); this excess in mortality was confirmed even when initial illness severity was taken into account (odds ratio= 2.89; 95% CI 1.44, 5.80). CONCLUSIONS: The universal coverage of the National Health Service in Italy does not guarantee equitable access to CABG surgery for IHD patients. Factors related to SES are likely to influence poor prognosis after CABG surgery.

Exposure to benzene in urban workers: environmental and biological monitoring of traffic police in Rome.

OBJECTIVES: To evaluate the contribution of traffic fumes to exposure to benzene in urban workers, an investigation on personal exposure to benzene in traffic police from the city of Rome was carried out. METHODS: The study was performed from December 1998 to June 1999. Diffusive Radiello personal samplers were used to measure external exposures to benzene and alkyl benzenes during the workshift in 139 policemen who controlled medium to high traffic areas and in 63 office police. Moreover, as biomarkers of internal exposure to benzene, blood benzene, and urinary trans, trans-muconic and S-phenyl mercapturic acids were measured at the beginning and at the end of the workshift in 124 traffic police and 58 office police. RESULTS: Time weighted average (TWA) exposure to benzene was consistently higher among traffic police than among indoor workers (geometric mean 6.8 and 3.5 microg/m(3), respectively). Among the traffic police, the distribution of individual exposures was highly asymmetric, skewed toward higher values. Mean ambient benzene concentrations measured by municipal air monitoring stations during workshifts of traffic police were generally higher (geometric mean 12.6 microg/m(3)) and did not correlat with personal exposure values. In particular, no association was found between highest personal exposure scores and environmental benzene concentrations. Among the exposure biomarkers investigated, only blood benzene correlated slightly with on-shift exposure to benzene, but significant increases in both urinary trans, trans-muconic and S-phenylmercapturic acids were found in active smokers compared with non-smokers, irrespective of their job. CONCLUSION: The exposure to traffic fumes during working activities in medium to high traffic areas in Rome may give a relatively greater contribution to personal exposure to benzene than indoor sources present in confined environments. Smoking significantly contributed to internal exposure to benzene in both indoor and outdoor workers.

Malignant mesothelioma in Rome, Italy 1980-1995. A retrospective study of 79 patients.

AIM AND BACKGROUND: To evaluate the characteristics of a case-series of 79 malignant mesothelioma patients collected from the main teaching hospital of Rome, Italy, and other local clinics of Latium Region and to assess the role of asbestos exposure, since previous studies on the occurrence of the disease in this area were lacking. METHODS: The study included cytohistologically diagnosed malignant mesothelioma (71 pleural, 7 peritoneal, and 1 testicular tunica vaginalis) detected or referred for consultation during the period 1980-1995. Information regarding occupational and/or nonoccupational exposures was derived from clinical records and interviews, when available. RESULTS: Patients were resident in Rome and other towns of Latium; a few were from other parts of central and southern Italy. Exposure to asbestos was assessed for 45.5% of patients, another 45.5% had unknown exposure, and for the remaining 9% such information was lacking. Occupational exposure occurred in 53% of men for whom information was available and nonoccupational exposure occurred in 20% of women. The study identified two clusters of cases from an asbestos-cement plant and a facility where asbestos was ubiquitous. Furthermore, most exposed subjects reported occupations in the construction industry, which is particularly active in the Latium Region; others were railroad workers, naval mechanics and navy personnel, bakers, explosive workers and car mechanics. A few patients reported indoor exposure to asbestos at home and/or in the workplace. CONCLUSIONS: The study confirmed that mesothelioma risk is present in several job titles of the construction industry, and it is no longer confined to workers employed in the manufacture or application of asbestos products. The occurrence of malignant mesothelioma in patients with unexpected occupational and nonoccupational exposures indicates the need for further investigation on previously underestimated exposures.

Air pollution and hospital admissions for respiratory conditions in Rome, Italy.

Most of the evidence regarding the association between particulate air pollution and emergency room visits or hospital admissions for respiratory conditions and asthma comes from the USA. European time-series analyses have suggested that gaseous air pollutants are important determinants of acute hospitalization for respiratory conditions, at least as important as particulate mass. The association between daily mean levels of suspended particles and gaseous pollutants (sulphur dioxide, nitrogen dioxide, carbon monoxide, ozone) was examined. The daily emergency hospital admissions for respiratory conditions in the metropolitan area of Rome during 1995-1997 were also recorded. Daily counts of hospital admissions for total respiratory conditions (43 admissions day(-1)), acute respiratory infections including pneumonia (18 day(-1)), chronic obstructive pulmonary disease (COPD) (13 day(-1)), and asthma (4.5 day(-1)) among residents of all ages and among children (0-14 yrs) were analysed. The generalized additive models included spline smooth functions of the day of study, mean temperature, mean humidity, influenza epidemics, and indicator variables for day of the week and holidays. Total respiratory admissions were significantly associated with same-day level of NO2 (2.5% increase per interquartile range (IQR) change, 22.3 microg x m(-3)) and CO (2.8% increase per IQR, 1.5 mg x m(-3)). No effect was found for particulate matter and SO2, whereas O3 was associated with admissions only among children (lag 1, 5.5% increase per IQR, 23.9 microg x m3). The effect of NO2 was stronger on acute respiratory infections (lag 0, 4.0% increase) and on asthma among children (lag 1, 10.7% increase). The admissions for all ages for asthma and COPD were associated only with same-day level of CO (5.5% and 4.3% increase, respectively). Multipollutant models confirmed the role of CO on all respiratory admissions, including asthma and COPD, and that of NO2 on acute respiratory infections. Among children, O3 remained a strong indicator of acute respiratory infections. Carbon monoxide and photochemical pollutants (nitrogen dioxide, ozone) appear to be determinants of acute respiratory conditions in Rome. Since carbon monoxide and nitrogen dioxide are good indicators of combustion products from traffic related sources, the detected effect may be due to unmeasured fine and ultrafine particles.
