Myceligenerans crystallogenes sp. nov., isolated from Roman catacombs.
(33/133)
Three xylan-degrading actinobacterial strains were isolated from different sampling sites in the Roman catacombs of Domitilla and San Callisto. The organisms showed morphological and chemotaxonomic properties such as peptidoglycan type A4alpha, L-lys-L-thr-D-Glu; whole-cell sugars (glucose, mannose and galactose); octa-, hexa- and tetrahydrogenated menaquinones with nine isoprene units; phosphatidylglycerol and diphosphatidylglycerol as the major phospholipids; anteiso-C(15 : 0), iso-C(15 : 0) and iso-C(16 : 0) as the predominant fatty acids; and a DNA G+C content of 72 mol%. These features are consistent with affiliation of these isolates to the genus Myceligenerans. The three isolates shared a 16S rRNA gene similarity of 99.9 % and were most closely related to Myceligenerans xiligouense DSM 15700T (97.9 % sequence similarity). The low level of DNA-DNA relatedness (about 14 %) and the differences in phenotypic characteristics between the novel strains and M. xiligouense DSM 15700T justify the proposal of a novel species of the genus Myceligenerans, Myceligenerans crystallogenes sp. nov., with CD12E2-27T (= HKI 0369T = DSM 17134T = NCIMB 14061T = VTT E-032285T) as the type strain.

An outbreak of aseptic meningitis due to echovirus 30 associated with attending school and swimming in pools.
(34/133)
OBJECTIVES: To identify the risk factors of an outbreak of meningitis associated with echovirus 30-infection that occurred in Rome, Italy, in late 1997 among children from two different schools. METHODS: A case-control study was carried out. A case was defined as a child from either of the two schools, A or B, who presented meningitis-like (fever, headache and vomiting), diarrhea, or respiratory tract symptoms. All asymptomatic students were included in the analysis as controls. RESULTS: Among 446 pupils (80%) who answered the questionnaire, 68 met the case definition. Twenty pupils developed a meningitis-like illness. Echovirus 30 was isolated from cerebrospinal fluid (CSF) in four and from stools in six. Forty-eight pupils reported other symptoms. The attack rate was 10.8% in school A and 0.8% in school B for meningitis-like illness; it was 12% and 10%, respectively, for other enterovirus-like illnesses. The risk of meningitis-like illness was higher among children attending school A (crude OR = 14.9; 95% CI = 4.3-52.1), among children using any public pool (OR = 3.8; 95% CI = 1.5-9.9) and those using an outside swimming pool X (OR=13.4; 95% CI=2.7-65.8 versus no swimming pool and OR = 8.3; 95% CI = 1.1-62.6 versus other pools). The epidemic curve appears to suggest a person-to-person transmission. CONCLUSIONS: The epidemic occurred by person-to-person transmission in a number of classrooms and at swimming pool X. (+info)
An integrated psychological strategy for advanced colorectal cancer patients.
(35/133)
BACKGROUND: There is evidence regarding the usefulness of psychosocial intervention to improve health related quality of life (HRQOL) in adult cancer patients. The aim of this report is to describe an integrated approach and to evaluate its feasibility in routine clinical practice in 98 advanced colorectal cancer (ACC) patients during chronomodulated chemotherapy. METHODS: A prospective non-randomised design was developed and applied in a cancer out-patient setting. The intervention consisted of an integrated approach, whereby the psycho-oncologist had an active role in the health care team with the physician and routinely included psychological understanding in the medical treatment program. The psychological evaluation assessed: a) adaptation, awareness, psychopathological disorders through a psychodynamic interview; b) anxiety and depression using the HAD scale; c) subjective perception of care quality through a structured interview and d) HRQOL evaluation assessment with the EORTC QLQ C30. Outcomes data were collected before and after 18 weeks of chemotherapy. RESULTS: After 18 weeks of chemotherapy a significant improvement of adaptation and awareness was observed. The HADs results showed a significant decrease in anxiety when compared to pre-treatment. The structured interview showed a significant increase of patients who positively experienced the impact of medical treatment on HRQOL, anxiety, depression, interpersonal relationships, free-time and who positively experienced the care quality. Indeed, a majority of patients positively experienced the team relationship modality during the whole treatment. All scales on the EORTC questionnaire remained unchanged during the entire treatment. CONCLUSION: Our results suggest that it is feasible to carry out an integrated approach during chemotherapy. These results seem to support the integrated approach as a tool in aiding advanced colorectal cancer patients' ability to cope with their diagnosis and treatment although an appropriately designed study is required to confirm this.

Fetal alcohol syndrome disorders: experience on the field. The Lazio study preliminary report.
(36/133)
In Italy, little is known about the problems related to alcohol drinking during pregnancy. In this paper, the Italian literature about this subject is briefly reviewed. This first Italian experience of a field study, aimed to the assessment of the prevalence of fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorders (FASD) in an area in the Rome province (Lazio region) is reported. This in-field study was performed in the school years 2003-2004 and 2004-2005 in cooperation with American researchers, most from University of New Mexico (Albuquerque), and Italian researchers from University "la Sapienza" of Rome. First grade children (n(o) = 1,086) of primary school were contacted to enter in the in-school study for the detection of FAS and FASD and were examined by the experts team of clinicians, pediatrics, psychologists. Preliminary consideration and the implications of this study for FASD prevention are discussed. (+info)
Clinical features and outcome of familial chronic lymphocytic leukemia.
(37/133)
The prognostic impact of the presence of a familial trait was analyzed in 1449 patient with chronic lymphocytic leukemia (CLL). A family history of hematologic malignancy (HM) was identified in 181 cases (12.5%) and recorded more frequently among female than male patients (HM: p < 0.05; CLL: p < 0.05). The relative was affected by CLL in 89 cases (6%). Familial and sporadic cases showed non-statistically different proportions of advanced stages (10.8 vs 7.1%) and patients requiring therapy (55 vs 60%) and a similar survival probability at 10 years (67 vs 66%). These data suggest that in CLL the presence of a familial trait does not imply an adverse prognosis. (+info)
Mortality study of employees in a factory of recovery and refining of catalytic converters in Rome, Italy.
(38/133)
The study objective is to describe cause specific mortality of employees in a plant engaged in production, recovery and refining of catalytic converters located in Rome. Previous epidemiological studies conducted in similar plants are not available. A total of 828 workers (642 males and 186 females) were followed up between 1956 and 31-12-2003. Cause specific standardized mortality ratio (SMR) and 90% confidence intervals (CI) were computed using regional rates for comparison. Among males hired between 1956 and 1993, followed up until 31/12/2003, mortality for all causes (SMR 0,8; 90% CI 0,7-1,0; 85 observed) and all neoplasms (SMR 0,6; 90% CI 0,42-0,87; 20 observed) is below expected; an increase is present for liver cirrhosis (SMR 2,74; 90% CI 1,47-5,1; 7 observed) and brain cancer (SMR 5,24; 90% CI 2,3-11,90; 4 observed). The present investigation complies with the proposed scientific standards for occupational cohort studies. The study was not prompted by well defined a priori hypotheses but it is included in a process intended to typify a potentially polluted site; the absence of a priori hypotheses and of previous epidemiological evidence, prevent from a causal interpretation of the increased mortality from liver cirrhosis and brain cancer. The implementation of cohort studies in industrial sites where industrial activities similar to the one here examined are present, are highly recommended. (+info)
Socioeconomic differentials in premature mortality in Rome: changes from 1990 to 2001.
(39/133)
BACKGROUND: While socioeconomic inequalities in mortality have widened in many countries, evidence of social differentials is scarce in Southern Europe. We studied temporal changes in premature mortality across socioeconomic groups in Rome between 1990 and 2001. METHODS: We analysed all 126,511 death certificates of residents of Rome aged 0-74 years registered between 1990-2001. A 4-level census block index based on the 1991 census was used as an indicator of socioeconomic position (SEP). Using routine mortality data, standardised mortality rates (per 100,000 inhabitants) were calculated by SEP and gender for four time periods. Rate ratios were used to compare mortality by gender and age. RESULTS: Overall premature mortality decreased in both genders and in all socioeconomic groups; the change was greater in the highest socio-economic group. In both men and women, inequalities in mortality strengthened during the 1990s and appeared to stabilise at the end of the 20th century. However, for 60-74 year old women the gap continued to widen. CONCLUSION: Socioeconomic inequalities in health in Rome are still present at the beginning of the 21st century. Strategies to monitor the impact of SEP on mortality over time in different populations should be implemented to direct health policies. (+info)
A questionnaire study on knowledge of and attitudes toward epilepsy in schoolchildren and university students in Rome, Italy.
(40/133)
PURPOSE: To estimate the knowledge of and attitudes toward epilepsy in schoolchildren and university students in Rome. METHODS: We administered a custom-designed questionnaire in Italian on general knowledge, specific knowledge and social impact of epilepsy to a random sample of upper-middle class pupils and university undergraduate students in Rome. RESULTS: The young people we studied have a reasonable knowledge of epilepsy: as many as 91% claimed to know something about the disease. Yet only 16% correctly stated the prevalence as being about 1 in 100. Middle-school pupils and university graduates consider epilepsy as an illness from which patients rarely recover and one that creates problems in finding employment. The largest number of correct answers for nearly all the questionnaire items came from university students. CONCLUSIONS: These findings suggest that apart from an encouragingly large number of the subjects we studied claim to know something about epilepsy (91% today versus 73% 22 years ago), Italian students still know little about epilepsy. These preliminary data should provide a starting point for a future in-depth population-based survey and information campaigns at schools in the Rome metropolitan area. (+info)
