Isonymy and the structure of the Provençal-Italian ethnic minority

Surnames were obtained for the second half of the 20th century from civil and religious marriage registers on fifteen Proven?al-Italian and five Italian villages of Cuneo Province, Italy. To insert in the analysis an outward comparison, surnames from two Italian villages of Turin Province, one parish of Turin, one village of Alessandria Province and one village of Asti Province were also collected. Ethnicity does not seem to be the main factor affecting the present genetic structure of the Proven?al-Italians. They are an open community, and evidence the end of the genetic isolation of the alpine populations.     

The Brain Collections of the Museum of Anthropology and Ethnography, University of Turin: Re-Evaluation and Scientific Investigation

The study of brain collections has played an important role in research on the Natural History of Man. Current knowledge on cerebral morphological evolution and development of the psyche, from non-human primates to Man, is the result of analyses of endocranial casts and brains collected in the nineteenth century from the various primate species dissected. This paper presents the brain collections of non-human and human primates housed in the Museum of Anthropology and Ethnography of the University of Turin put together in the early 1900s by A. Marro, father of Prof. Giovanni Marro, the founder of the Museum. These collections, which have required constant interventions aimed at their preservation and scientific re-evaluation, have undoubted historical interest and are essential to define Man, both biologically and culturally.     

Psychometric comparison of students in medicine and other faculties: social factors and psychologic symptoms

Few studies have investigated personality and psychopathological profiles associated to the choice of university education. Our study examined students from four faculties of Turin University, in Turin, Italy (Medicine, Engineering, Education, Law), comparing sociodemographic features, personality characteristics and psychiatric symptoms. A heterogeneous group of 1,323 students were assessed using a semistructured interview, the Personality Diagnostic Questionnaire-Revised (PDQ-R), and the Symptoms Checklist 90 (SCL-90). Statistical analysis included four logistic regression models, each fitted for one faculty, considering the other three as a control group. Associations were found in Medical and Engineering students concerning type of high school, school final score, and father?s socioeducational level. Factors associated with students of Law and Education included socioeducational characteristics, but stronger correlations were seen with PDQ-R personality scales and SCL-90 symptom clusters. In conclusion, four different profiles were identified. Medicine was not significantly related to personality and psychiatric factors. Engineering was related to male gender, choice of technical high school and father?s social level. Law was related to female gender and narcissistic personality profile. These data may be useful for counseling activities addressed to high school and university students.     

A multi-channel, tele-metric system for analysing biological data: extern work, the electrocardiogram, etc...

A new multichannel, telemetric system for analysing biological data was developed and tested, in collaboration with the Berta Firm in Turin. This system was tested on subjects at 4650 meters in Peru. The results obtained show the usefulness of this tool. In addition it is very good in evaluating the progress of post-myocardial infarctuated patients.     

Sequential sampling plan for Cameraria ohridella (Lepidoptera: Gracillariidae) on horse chestnut tree

A fixed precision sequential sampling plan for estimating the density of the horse chestnut, Aesculus hippocastanum L., leafminer Cameraria ohridella Deschka & Dimic (Lepidoptera: Gracillariidae) was developed. Data were collected from 2002 to 2004 in Turin, northwestern Italy, with the aim of developing a sampling strategy for estimating populations of C. ohridella mines. Taylor's power law was used as a regression model. Sampling parameters were estimated from 216 data sets, and an additional 110 independent data sets were used to validate the fixed precision sequential sampling plan with resampling software. Covariance analysis indicated that there were not significant differences in the coefficient of Taylor's power law between heights of the foliage, months, and years. Dispersion patterns of C. ohridella were determined to be aggregated. The parameters of the Taylor's power law were used to calculate minimum sample sizes and sampling stop lines for different precision levels. Considering a mean density value of five mines per leaf, an average sample number of only 49 leaves was necessary to achieve a desired precision level of 0.25. As the precision level was increased to 0.10, the average sample size increased to 303 leaves. The sequential sampling plan should provide an effective management of C. ohridella in the urban areas, minimizing sampling time and cost, and at the same should be an effective tool to reduce insecticide applications and prevent the esthetic damage.     

Presence of pathogenic yeasts in the feces of the semi-domesticated pigeon (Columba livia, Gmelin 1789, urban type) from the city of Turin

The results of a survey on the presence of pathogenic yeasts in pigeon droppings collected in Turin, are shown. The study was carried out in 8 densely populated areas, where human-animal contact is highest. A total of 427 pigeon dropping samples, most of which fresh, were collected. 550 yeast colonies, clinically interesting or at least pathologically significant, were isolated by the identification routine methods. The yeasts belong to the following species: Candida albicans, C. humicola, C. krusei, C. guillermondii, C. lypolitica, C. lambica, C. parapsilosis, C. tropicalis, C. rugosa, C. zeylanoides, Cryptococcus albidus, C. laurentii, C. neoformans, Hansenula anomala, Geotrichum sp., Kloekera apiculata, Rhodotorula glutinis, R. rubra, Saccharomyces cerevisiae, Torulopsis candida, T. glabrata, Trichosporon beigelii, T. capitatum, T. cutaneum, T. pullulans.     

Is TW3 height prediction more accurate than TW2? Preliminary data

BACKGROUND/AIMS: Skeletal maturation is considered a reliable variable in evaluating the 'tempo' of growth. It is important in the diagnosis of endocrinological diseases, in chronic diseases, in hormonal therapy follow-up and in computing height prediction for prognostic and therapeutic purposes. It is also used when chronological age is not available for minors without known birth dates. There are different methods to evaluate skeletal maturation and height prediction. The Tanner-Whitehouse (TW) method 2 (TW2) has been considered to be the most useful method so far, and has recently been updated with modified height prediction equations (TW2-Mark II). TW3 is the newest method. The aim of this study is to evaluate whether TW3 is more accurate in the assessment of height prediction than TW2-Mark II in a sample of healthy north Italian subjects. METHODS: Anthropometrical data were collected as part of a survey in 1977-1978 in Turin. The sample involved 1,384 healthy children. The children, now adults, have been traced and recalled to measure their final height in order to test height prediction reliability. At present, we have collected 118 adult heights. RESULTS: According to the TW2 method 40% of the males had a height prediction error larger than +/- residual SD (4.1 cm), and with TW3 this was 32.9%. The female height prediction error with TW2 was larger than +/- residual SD (3.6 cm) in 29.2% of girls, and the same value was found with TW3. CONCLUSION: According to our preliminary data, TW3 does not represent any real progress.     

Dogs' parasite and zoonotic risk: from old to new "emergencies" in the North-West of Italy

Toxocariasis due to soil contamination from dog and cat faeces has been long described and represents one of the zoonotic risk linked with pets presence in human settlements. Soil samples were collected from private backyards and school playgrounds in Turin and tested for the presence of Toxocara spp. eggs. Samples from dogs and cats living in the same area were also analysed and our results seem to indicate a decrease in soil contamination respect to a survey carried out in 1985. Considering that recently new foci of Canine Leishmaniosis and the presence of competent sand fly vectors have also been reported in the North-West of Italy, a survey was carried out on dogs and humans living in Asti province. To assess the risk of local Leishmania infantum transmission between dog and humans, samples were also analysed by Restriction Fragment Length Polymorphism (PCR-RFLP). Our results have shown that more than 10% of autochthonous dogs and human being living in this previously non-endemic area have been infected by L. infantum. The identity of PCR-RFLP patterns from 3 human clinical cases and from the dogs of one of them allows us to confirm the autochthonous origin of these cases.     

XRCC1 and ERCC1 variants modify malignant mesothelioma risk: a case-control study

Malignant pleural mesothelioma (MPM) is a rare aggressive tumor associated with asbestos exposure. The possible role of genetic factors has also been suggested and MPM has been associated with single nucleotide polymorphisms (SNPs) of xenobiotic and oxidative metabolism enzymes. We have identified an association of the DNA repair gene XRCC1 with MPM in the population of Casale Monferrato, a town exposed to high asbestos pollution. To extend this observation we examined 35 SNPs in 15 genes that could be involved in MPM carcinogenicity in 220 MPM patients and 296 controls from two case-control studies conducted in Casale (151 patients, 252 controls) and Turin (69 patients, 44 controls), respectively. Unconditional multivariate logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). Two DNA repair genes were associated with MPM, i.e. XRCC1 and ERCC1. Considering asbestos-exposed only, the risk increased with the increasing number of XRCC1-399Q alleles (Casale: OR=1.44, 95%CI 1.02-2.03; Casale+Turin: OR=1.34, 95%CI 0.98-1.84) or XRCC1 -77T alleles (Casale+Turin: OR=1.33, 95%CI 0.97-1.81). The XRCC1-TGGGGGAACAGA haplotype was significantly associated with MPM (Casale: OR=1.76, 95%CI 1.04-2.96). Patients heterozygotes for ERCC1 N118N showed an increased OR in all subjects (OR=1.66, 95%CI 1.06-2.60) and in asbestos-exposed only (OR=1.59, 95%CI 1.01-2.50). When the dominant model was considered (i.e. ERCC1 heterozygotes CT plus homozygotes CC versus homozygotes TT) the risk was statistically significant both in all subjects (OR=1.61, 95%CI 1.06-2.47) and in asbestos-exposed only (OR=1.56, 95%CI 1.02-2.40). The combination of ERCC1 N118N and XRCC1 R399Q was statistically significant (Casale: OR=2.02, 95%CI 1.01-4.05; Casale+Turin: OR=2.39, 95%CI 1.29-4.43). The association of MPM with DNA repair genes support the hypothesis that an increased susceptibility to DNA damage may favour asbestos carcinogenicity.     

763. GUNDELIA TOURNEFORTII

Gundelia tournefortii L. (Compositae: Gundelieae) is described and illustrated, and its strange inflorescence morphology highlighted. The history of the discovery of this fascinating plant is covered from one of the first natural history collections made in the late 16th century in the Levant. The problematic taxonomy of this genus is discussed, both supragenerically and infragenerically. The species has very rarely been cultivated throughout its recent history, making a commentary on its cultivation and propagation a little difficult. The wide range of uses cover a history dating back at least 10,000 years, from the Neolithic sites of Iraq and Turkey, to its present day usage in the region. The importance of herbarium specimen data, as well as literature, for the ethnobotany of taxa is emphasized. A possible biblical connection is commented on in relation to the Shroud of Turin.     

Seroprevalence study of Tick-borne encephalitis, Borrelia burgdorferi, Dengue and Toscana virus in Turin Province

Tick borne encephalitis virus (TBEV) is present in some European countries and it is transmitted by a tick bite. Ixodes ricinus is the main vector of the infection in Italy, where fortunately clinical neurological manifestations, typical of the more serious phase of the disease, are very rarely observed. This behaviour is different from other endemic Euroasiatic areas where numerous cases of encephalitis are described. However TBE transmission has not been widely investigated in Italy and available epidemiological data have been obtained only by studies performed in Central and Northern Regions of the country. In addition seroepidemiological researches were made prevalently on subjects at high risk of tick bite, such as hunters or forest guards from Trentin and Central Italy. No precise information about TBE virus diffusion was available in the Piedmont before our investigations. We found that hunters and wild boar breeders seem to be particularly exposed to the risk of TBE virus infection in Turin Province and in particular in the Susa valley, although no neurological involvement was observed in our population. In particular a seroprevalence of about 5% was detected by the use of purified antigens ELISA test, amongst the subjects at high risk of tick bite. Moreover low risk individuals showed a seroprevalence of below 2%. In addition a parallel seroepidemiological study was performed in Turin Province for Borrelia burgdorferi, the aetiological agent of Lyme disease, also transmitted by tick bite (e.g. Ixodes ricinus), for Dengue and Toscana (TOS) arboviruses, respectively transmitted by Aedes mosquitoes and phlebotomes. Data reported here demonstrate only a sporadic presence in our population of antibodies against Borrelia and Dengue infection. Moreover using an ELISA test performed with viral purified nucleoprotein, we reported a total percentage of about 3% of subjects positive for TOSV.     

Epidemiology of dermatophytosis in the metropolitan area of Turin

The study here presented deals with the problem of the dermatophytoses in Piedmont, with regard to their etiologic and, more generally, their epidemiologic aspects. From 586 patients who presented themselves at the Dermatology Clinic of the University of Turin, for mycological examinations, between the period of March–November 1979, 100 positive cases were selected. The study was set under way with the filling in of special forms for the epidemiologic investigation and with the classification of some species of fungi which had been isolated beforehand, using the methods of Ajello, Rebell and Taplin (1, 12). From the data collected, it was ascertained that the principal etiologic agents isolated were, in order of frequency: Microsporum canis, Tricophyton rubrum, Epidermophyton floccosum and T. mentagrophytes. The subjects that were affected most by these dermatophytes were the young (babies and schoolchildren) with the location of the infections being mostly in the scalp. As regards the period of manifestation, May–June and September–October were the periods with the highest incidence. It is noteworthy that the diffusion of the principal dermatophytes could be attributed to domestic animals such as cats and dogs.     

Observations on the Turin specimen ofMesopithecus pentelici (Wagner, 1839)

A fossil specimen ofMesopithecus pentelici Wagner, 1839, from the Pikermi paleontological assemblage and currently housed at the Geological Museum of the Earth Sciences Department of the University of Turin, is described herein. The left mandibular ramus displays dental features which permit us to assign it to a young female individual. Anatomical patterns are discussed and are compared with other similar remains of more recent discovery.     

Variation among early North American crania

The limited morphometric work on early American crania to date has treated them as a single, temporally defined group. This paper addresses the question of whether there is significant variability among ancient American crania. A sample of 11 crania (Spirit Cave, Wizards Beach, Browns Valley, Pelican Rapids, Prospect, Wet Gravel male, Wet Gravel female, Medicine Crow, Turin, Lime Creek, and Swanson Lake) dating from the early to mid Holocene was available. Some have recent accelerator mass spectrometry (AMS) dates, while others are dated geologically or archaeologically. All are in excess of 4500 BP, and most are 7000 BP or older. Measurements follow the definitions of Howells [(1973) Cranial variation in man, Cambridge: Harvard University). Some crania are incomplete, but 22 measurements were common to all fossils. Cranial variation was examined by calculating the Mahalanobis distance between each pair of fossils, using a pooled within sample covariance matrix estimated from the data of Howells. The distance relationships among crania suggest the presence of at least three distinct groups: 1) a middle Archaic Plains group (Turin and Medicine Crow), 2) a Paleo/Early Archaic Great Lakes/Plains group (Browns Valley, Pelican Rapids, Lime Creek), and 3) a spatially and temporally heterogeneous group that includes the Great Basin/Pacific Coast (Spirit Cave, Wizards Beach, Prospect) and Nebraska (Wet Gravel specimens and Swanson Lake). These crania were also compared to Howells' worldwide recent sample, which was expanded by including six additional American Indian samples. None of the fossils, except for the Wet Gravel male, shows any particular affinity to recent Native Americans; their greatest similarities are with Europe, Polynesia, or East Asia. Several crania would be atypical in any recent population for which we have data. Browns Valley, Pelican Rapids, and Lime Creek are the most distinctive. They provide evidence for the presence of an early population that bears no similarity to the morphometric pattern of recent American Indians or even to crania of comparable date in other regions of the continent. The heterogeneity among early American crania makes it inadvisable to pool them for purposes of morphometric analysis. Whether this heterogeneity results from different early migrations or one highly differentiated population cannot be established from our data. Our results are inconsistent with hypotheses of an ancestor-descendent relationship between early and late Holocene American populations. They suggest that the pattern of cranial variation is of recent origin, at least in the Plains region.     

Effect of Environmental Pollution on the Chromosomal Variability of Chironomus Riparius

Different frequencies of chromosomal alterations in salivary gland polytene chromosomes AB, CD and EF were described in larvae of Chironomus riparius (syn. Chironomus thummi) from the trace metal-polluted station of Santena on the river Banna, near Turin, and from the unpolluted station of Corio (40 Km from Turin) which was taken as a reference area. In a sample of 56 larvae from Santena, no specimen with the standard karyotype in all cells of the salivary glands was found. Different types of aberrations were found: 33 paracentric and five pericentric inversions, three deficiencies, four amplified sections and one chromatid break. Fifteen out of the 38 inversions and two amplified sections appeared to be inherited, while all the other aberrations were somatic. Most of the aberrations' breakpoints were located on both sides of the centromere regions, where constitutive heterochromatin is present. Also functional alterations were observed (mainly telomere and centromere decondensations and nine novel puffs). In a sample of 49 larvae of a population from the well-preserved area of Corio only six somatic and one inherited paracentric inversions were found. These results suggest that the strong destabilization of the genomes of C. riparius larvae from Santena could be a reaction to the activity of the toxic substances present in the polluted sediments of the river Banna. This revised version was published online in August 2006 with corrections to the Cover Date.     

Sources of fungal contamination in a burn-care unit

A microbiological study was carried out in the burn-care unit of the Centro Traumatologico Ortopedico of Turin (Italy) in order to detect the most important sources of fungal contamination in patients at high risk of infection. Identification of the fungi was carried out only for those of medical mycological interest, with the exclusion of the yeast isolates.     

Vincenzo Malacarne (1744-1816): a researcher in neurophysiology between anatomophysiology and electrical physiology of the human brain

Since his first years at Turin until the last years of his life at Padua, Vincenzo Malacarne devoted most of his time to the examination of the structures and the various parts of which the cerebellum and the human brain are composed. He is rightly considered as one of the first to have correctly described the anatomy of the cerebellum, as well in the field of human anatomy and comparative anatomy. However, his work cannot be reduced to these studies. He worked out a cerebral physiology, with organic and intellectual phenomena in mind, established on an anatomopsychic parallelism. This parallelism is itself founded on a rational and mathematical criterion: the number of lamellae contained in the cerebellum. A letter written by him in 1792 and addressed to Abbot Denina was recently found by the present author in November 2005 at the Academy of Sciences of Turin. Malacarne exposed his project of studying the animal electricity put forward by Galvani within the cerebral organ. May it be that Malacarne had in mind the physiology of his time while trying to record an electric activity within the brain?     

The Effect on Mortality of Fluconazole or Echinocandins Treatment in Candidemia in Internal Medicine Wards

The incidence of candidemia has increased over the past two decades, with an increased number of cases in Internal Medicine and a prevalence ranging from 24% to 57%. This single-center retrospective study was performed to evaluate the epidemiology and the risk factors associated with mortality of candidemia in patients admitted to Internal Medicine wards (IMWs) of the City of Health and Sciences, Molinette Hospital, Turin, from January 2004 to December 2012. For each patient, demographic, clinical and microbiological data were collected. A case of candidemia was defined as a patient with at least one blood culture positive for Candida spp. Amongst 670 episodes of candidemia, 274 (41%) episodes occurred in IMWs. The mortality was 39% and was associated at multivariate analysis with sepsis, cirrhosis and neurologic diseases, whilst removal of central venous catheter ≤48h was significantly associated with survival. In the 77 patients treated with early antifungal therapy the mortality was 29% and was not significantly different with caspofungin or fluconazole, whilst in patients with definitive therapy the mortality was significantly lower with echinocandins compared to fluconazole (11.7% Vs. 39%; p=0.0289), a finding confirmed by multivariate analysis. The mortality was significantly associated with sepsis, cirrhosis and neurologic diseases, whilst CVC removal ≤48h was associated with survival. In patients with early therapy, fluconazole or caspofungin were equally effective. However, echinocandins were significantly more effective as definitive treatment, a finding not explained by differences in treatment delays. Further studies are needed to understand the full potential of these different therapeutic strategies in IMWs.     

Clinicopathological Characteristics and Prognosis of Poorly Differentiated Thyroid Carcinoma Diagnosed According to the Turin Criteria

ObjectivePoorly differentiated thyroid carcinoma (PDTC) is the primary cause of death in patients with nonanaplastic follicular cell-derived thyroid carcinoma. We purposed to identify the clinical and pathological characteristics of PDTC and their relationship with prognosis.MethodsA retrospective analysis was conducted on patients diagnosed with PDTC at our institution from 2010 to 2018. All of their histopathology slides were reviewed by 2 experienced pathologists based on the Turin criteria. Furthermore, information regarding clinical characteristics, pathological characteristics, treatment strategy, and follow-up events were collected. The Kaplan-Meier method was used for survival analysis, while the log-rank test was used to compare survival curves. Then, the Cox proportional hazards model was used to perform univariate and multivariate analyses.ResultsTwenty-six patients with PDTC who met the Turin criteria were enrolled in this study. The median follow-up period of the included 26 patients was 76 months, while the 3- and 5-year survival rates were 40% and 18%, respectively. Notably, univariate analysis revealed that tumor size >4 cm (P = .038), extrathyroidal extension (ETE) (P = .020), distant metastases (P = .047), poorly differentiated areas >60% (P = .049), and Ki-67 labeling index >30% (P = .040) were associated with poor prognosis. On the other hand, multivariate analysis identified ETE (P = .007) and distant metastases (P = .031) as independent risk factors for poor prognosis.ConclusionPDTC is a rare carcinoma with high invasiveness and poor prognosis. Patients with ETE or distant metastases may have adverse outcomes.     

Immunological investigation of malaria and new perspectives in paleopathological studies

We applied a paleoimmunological investigation, using an immunoenzymatic assay revealing trophozoite derived Plasmodium falciparum histidine rich protein-2 antigen (PfHRP-2). The investigation was carried out on skin, muscle and bone samples. We examined predynastic egyptian mummies (3200 B.C.) from Gebelen, belonging to the Marro's Collection of the Anthropological and Ethnographic Museum of Turin, to assay the presence of malaria. The results obtained suggest an incidence of malaria of about 40% in the mummies of Gebelen group. Data are compatible with other observations effected on populations living in similar ecological conditions of malarial areas.
