Abstract
The immune system of semi- (from ≥105 to <110 years old) and supercentenarians (≥110 years old), i.e. oldest centenarians, is thought to have characteristics that allow them to reach extreme longevity in relatively healthy status. Thus, we investigated variations of the two principal subsets of Tγδ, Vδ1, and Vδ2, and their functional subsets using the markers defining Tαβ cells, i.e. CD27, CD45RA, in a cohort of 28 women and 26 men (age range 19-110 years), including 11 long-living individuals (from >90 years old to<105 years old), and eight oldest centenarians (≥105 years old), all of them were previously analysed for Tαβ and NK cell immunophenotypes on the same blood sample collected on recruitment day. Naïve Vδ1 and Vδ2 cells showed an inverse relationship with age, particularly significant for Vδ1 cells. Terminally differentiated T subsets (TEMRA) were significantly increased in Vδ1 but not in Vδ2, with higher values observed in the oldest centenarians, although a great heterogeneity was observed. Both naïve and TEMRA Vδ1 and CD8+ Tαβ cell values from our previous study correlated highly significantly, which was not the case for CD4+ and Vδ2. Our findings on γδ TEMRA suggest that these changes are not unfavourable for centenarians, including the oldest ones, supporting the hypothesis that immune ageing should be considered as a differential adaptation rather than a general immune alteration. The increase in TEMRA Vδ1 and CD8+, as well as in NK, would represent immune mechanisms by which the oldest centenarians successfully adapt to a history of insults and achieve longevity.

Abstract
Diffuse Large B-Cell Lymphomas (DLCBL) and mucosa-associated lymphoid tissue (MALT) are the two most common primary gastric lymphomas (PGLs), but have strongly different features. DLBCL is more aggressive, is frequently diagnosed at an advanced stage and has a poorer prognosis. The aim of this retrospective study was to explore the role of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (2-[18 F]-FDG-PET/CT) and radiomics features (RFs) in predicting the final diagnosis of patients with PGLs. Ninety-one patients with newly diagnosed PGLs who underwent pre-treatment 2-[18 F]-FDG-PET/CT were included. PET images were qualitatively and semi-quantitatively analyzed by deriving maximum standardized uptake value body weight (SUVbw), maximum standardized uptake value lean body mass (SUVlbm), maximum standardized uptake value body surface area (SUVbsa), lesion to liver SUVmax ratio (L-L SUV R), lesion to blood-pool SUVmax ratio (L-BP SUV R), metabolic tumor volume (gMTV) and total lesion glycolysis of gastric lesion (gTLG), total MTV (tMTV), TLG, and first-order RFs (histogram-related and shape related). Receiver-operating characteristic (ROC) curve analyses were performed to determine the differential diagnostic values of PET parameters. The final diagnosis was DLBCL in 54 (59%) cases and MALT in 37 cases (41%). PGLs showed FDG avidity in 83 cases (90%), 54/54 of DLBCL and 29/37 of MALT. All PET/CT metabolic features, such as stage of disease and tumor size, were significantly higher in DLBCL than MALT; while the presence of H. Pylori infection was more common in MALT. At univariate analysis, all PET/CT metrics were significantly higher in DLBCL than MALT lymphomas, while among RFs only Shape volume_vx and Shape sphericity showed a significant difference between the two groups. In conclusion we demonstrated that 2-[18 F]-FDG-PET/CT parameters can potentially discriminate between DLBCL and MALT lymphomas with high accuracy. Among first-order RFs, only Shape volume_vx and Shape sphericity helped in the differential diagnosis.

Abstract
This retrospective study investigated the prognostic role of disease dissemination features (Dmax and Dmaxbsa) measured by 2-[18F]FDG PET/CT in newly diagnosed Burkitt Lymphoma (BL) patients, comparing their performance with other metabolic parameters. We included 78 patients diagnosed with BL between 2010 and 2022 with an available baseline PET, interim PET/CT (iPET) and end of treatment PET/CT (eotPET) and with a minimum of two 2-[18F]FDG avid lesions present at the baseline scan. Dmax was calculated from the three-dimensional coordinates of the baseline metabolic tumor volume (MTV) by using LIFEx software; Dmaxbsa was calculated as Dmax normalized for body surface area according to the Du Bois method. We evaluated their effect on metabolic treatment response evaluated by PET, on progression free survival (PFS) and on overall survival (OS). Dmaxbsa was significantly associated with tumor stage, bulky and extranodal disease, MTV and TLG. At a median follow-up of 49 months, the median PFS and OS were 45 and 48 months. Dmax and Dmaxbsa were significantly higher in not complete metabolic response than complete metabolic response group at iPET and eotPET.As far as PFS, parameters including iPET/CT, eotPET/CT outcomes, MTV and TLG showed to be independent prognostic factors while Dmax and Dmaxbsa were not significantly associated with the outcome. Dissemination features, together with eotPET/CT results, MTV and TLG, demonstrated to be significantly correlated with OS. In conclusion, in this study we demonstrated that dissemination features derived by 2[18F]-FDG PET/CT were significantly correlated with response to treatment and long-term outcome, independently from other PET features.

Abstract
Cellular senescence is implicated in ageing and associated with a broad spectrum of age-related diseases. Importantly, a cell can initiate the senescence program irrespective of the organism's age. Various stress signals, including those defined as ageing hallmarks and alterations leading to cancer development, oncogene activation, or loss of cancer-suppressive functions, can trigger cellular senescence. The primary outcome of these alterations is the activation of nuclear factor (NF)-κB, thereby inducing the senescence-associated secretory phenotype (SASP). Proinflammatory cytokines and chemokines, components of this phenotype, contribute to chronic systemic sterile inflammation, commonly referred to as inflamm-ageing. This inflammation is linked to age-related diseases (ARDs), frailty, and increased mortality in older individuals. Additionally, senescent cells (SCs) accumulate in multiple tissues with age and are believed to underlie the organism functional decline, as demonstrated by models. An escalating effort has been dedicated to identify senotherapeutics that selectively target SCs by inducing apoptosis; these drugs are termed senolytics. Concurrently, small molecules that suppress senescent phenotypes without causing cell death are known as senomorphics. Both natural and synthetic senotherapeutics, along with immunotherapies employing immune cell-mediated clearance of SCs, currently represent the most promising strategies to combat ageing and ARDs. Indeed, it is fascinating to observe that information regarding the immune reaction to SCs indicates that regulation by specific lymphocyte subsets, elevated in the oldest centenarians, plays a role in attaining extreme longevity. Regardless, the application of methods already utilized in cancer treatment, such as CAR cells and monoclonal antibodies, broadens the spectrum of potential approaches to be utilized.

Abstract
Background and Objectives: Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in developed countries, which can evolve into aggressive lymphoma variants, a process called Richter transformation (RT). The aim of this retrospective study was to analyze the role of 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography (2-[18F]-FDG PET/CT) and its semiquantitative and radiomics features in detecting RT and evaluate the impact on overall survival (OS). Materials and Methods: One hundred and thirty-seven patients with histologically proven CLL were retrospectively recruited. PET/CT images were qualitatively and semiquantitatively examined by estimating the main metabolic parameters (the maximum standardized uptake value body weight (SUVbw), lean body mass (SUVlbm), body surface area (SUVbsa), lesion-to-blood-pool SUV ratio (L-BP SUV R), lesion-to-liver SUV ratio (L-L SUV R), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) and radiomics first- and second- order variables of the lesion with highest uptake. The role of these parameters in predicting RT and OS was analyzed. Results: One hundred and thirty (95%) PET/CT scans were positive, showing an increased tracer uptake at the site of disease, whereas the remaining 7 (5%) scans were negative. SUVbw, SUVlbm, SUVbsa, L-L SUV ratio, and L-BP SUV ratio were significantly higher in the RT group (p < 0.001 in all cases). Radiomics first- and second-order features were not significantly associated with RT. After a median follow-up of 44 months, 56 patients died; OS was significantly shorter in patients with RT than patients without RT (28 vs. 34 months; p = 0.002). Binet-stage, RT, and L-BP SUV R were shown to be independent prognostic features. Conclusions: Semiquantitative PET/CT parameters such as SUVbw, SUVlbm, SUVbsa, L-L SUV ratio and L-BP SUV ratio may be useful in discriminating patients with a high risk of developing RT, whereas Binet-stage, RT, and L-BP SUV R are also significant in predicting OS.

Abstract
The immunophenotype of oldest centenarians, i.e. semi- and supercentenarians, could provide important information about their ability to adapt to factors associated with immune changes, including ageing per se and chronic Cytomegalovirus infection. We investigated, by flow cytometry, variations in percentages and absolute numbers of immune cell subsets, focusing on T cells, and pro-inflammatory parameters in a cohort of 28 women and 26 men (age range 19-110 years). We observed variability in hallmarks of immunosenescence related to age and Cytomegalovirus serological status. The eight oldest centenarians showed the lowest percentages of naïve T cells, due to their age, and the highest percentages of T-effector memory cells re-expressing CD45RA (TEMRA), according to their cytomegalovirus status, and high levels of serum pro-inflammatory parameters, although their means were lower than that of remaining 90+ donors. Some of them showed CD8 naïve and TEMRA percentages, and exhaustion/pro-inflammatory markers comparable to the younger ones. Our study supports the suggestion that immune ageing, especially of oldest centenarians, exhibits great variability that is not only attributable to a single contributor but should also be the full result of a combination of several factors. Everyone ages differently because he/she is unique in genetics and experience of life and this applies even more to the immune system; everybody has had a different immunological history. Furthermore, our findings on inflammatory markers, TEMRA and CMV seropositivity in centenarians, discussed in the light of the most recent literature, suggest that these changes might be not unfavourable for centenarians, and in particular for the oldest ones.

Abstract
In this paper, we present demographic, clinical, anamnestic, cognitive, and functional data, as well as haematological, haematochemical, immunological, and genetic parameters of an exceptional individual: A.T., a semi-supercentenarian who held the title of the oldest living Italian male centenarian from 28 December 2020, to 23 September 2021. The purpose of this study is to provide fresh insights into extreme phenotypes, with a particular focus on immune-inflammatory parameters. To the best of our knowledge, this study represents the first phenotypic investigation of a semi-supercentenarian, illustrating both INFLA-score, a metric designed to assess the cumulative impact of inflammatory markers and indicators of age-related immune phenotype (ARIP), recognized as significant gauges of biological ageing. The aim of this study was, indeed, to advance our understanding of the role of immune-inflammatory responses in achieving extreme longevity. The results of laboratory tests, as well as clinical history and interview data, when compared to the results of our recent study on Sicilian centenarians, demonstrate an excellent state of health considering his age. Consistent with previous studies, we observed increased IL-6 inflammatory markers and INFLA score in A.T. More interestingly, the semi-supercentenarian showed values of ARIP indicators such as naïve CD4+ cells, CD4+/CD8+ ratio, and CD4+TN/TM ratio in the range of young adult individuals, suggesting that his immune system's biological age was younger than the chronological one. The results support the notion that the immune system can play a role in promoting extreme longevity. However, this does not rule out the involvement of other body systems or organs in achieving extreme longevity.

Abstract
The immune system of semi- and supercentenarians (i.e., the oldest centenarians) is believed to have peculiar characteristics that enable them to reach extreme longevity in a relatively healthy state. Therefore, in previous papers, we investigated, through flow cytometry, variations in the percentages of the main subsets of Tαβ and Tγδ cells in a Sicilian cohort of 28 women and 26 men (age range 19-110 years), including 11 long-living individuals (>90 years old) and 8 oldest centenarians. These investigations suggested that some observed immunophenotypic changes may contribute to the extreme longevity of the oldest centenarians. In the present study, to further characterize the immunophenotype of the oldest centenarians, we examined the percentages of Natural Killer (NK) cells identified as CD3-CD56 + CD16+ in the previously described Sicilian cohort. We found a highly significant increase in NK cell percentages with age. When stratified by gender, this significant increase with age was maintained in both sexes, with higher significance observed in males. Our findings on NK cells, together with the previously obtained results, discussed in the context of the literature, suggest that these changes are not unfavourable for centenarians, including the oldest ones, supporting the hypothesis that immune aging should be considered as a differential adaptation rather than a general immune alteration. These adapted immune mechanisms allow the oldest centenarians to successfully adapt to a history of insults and achieve remarkable longevity.

Abstract
We introduce the Fast Algorithm for Motion Correction (FALCON) software, which allows correction of both rigid and nonlinear motion artifacts in dynamic whole-body (WB) images, irrespective of the PET/CT system or the tracer. Methods: Motion was corrected using affine alignment followed by a diffeomorphic approach to account for nonrigid deformations. In both steps, images were registered using multiscale image alignment. Moreover, the frames suited to successful motion correction were automatically estimated by calculating the initial normalized cross-correlation metric between the reference frame and the other moving frames. To evaluate motion correction performance, WB dynamic image sequences from 3 different PET/CT systems (Biograph mCT, Biograph Vision 600, and uEXPLORER) using 6 different tracers (18F-FDG, 18F-fluciclovine, 68Ga-PSMA, 68Ga-DOTATATE, 11C-Pittsburgh compound B, and 82Rb) were considered. Motion correction accuracy was assessed using 4 different measures: change in volume mismatch between individual WB image volumes to assess gross body motion, change in displacement of a large organ (liver dome) within the torso due to respiration, change in intensity in small tumor nodules due to motion blur, and constancy of activity concentration levels. Results: Motion correction decreased gross body motion artifacts and reduced volume mismatch across dynamic frames by about 50%. Moreover, large-organ motion correction was assessed on the basis of correction of liver dome motion, which was removed entirely in about 70% of all cases. Motion correction also improved tumor intensity, resulting in an average increase in tumor SUVs by 15%. Large deformations seen in gated cardiac 82Rb images were managed without leading to anomalous distortions or substantial intensity changes in the resulting images. Finally, the constancy of activity concentration levels was reasonably preserved (<2% change) in large organs before and after motion correction. Conclusion: FALCON allows fast and accurate correction of rigid and nonrigid WB motion artifacts while being insensitive to scanner hardware or tracer distribution, making it applicable to a wide range of PET imaging scenarios.

Abstract
Recently, several studies introduced the potential prognostic usefulness of maximum tumor dissemination (Dmax) measured by 2-deoxy-2-fluorine-18-fluoro-D-glucose positron-emission tomography/computed tomography (18F-FDG PET/CT). Dmax is a simple three-dimensional feature that represents the maximal distance between the two farthest hypermetabolic PET lesions. A comprehensive computer literature search of PubMed/MEDLINE, Embase, and Cochrane libraries was conducted, including articles indexed up to 28 February 2023. Ultimately, 19 studies analyzing the value of 18F-FDG PET/CT Dmax in patients with lymphomas were included. Despite their heterogeneity, most studies showed a significant prognostic role of Dmax in predicting progression-free survival (PFS) and overall survival (OS). Some articles showed that the combination of Dmax with other metabolic features, such as MTV and interim PET response, proved to better stratify the risk of relapse or death. However, some methodological open questions need to be clarified before introducing Dmax into clinical practice.

Abstract
Rhus coriaria Linn is a little plant growing in the Mediterranean basin, including Sicily, where it is known as Sicilian Sumac. Since antiquity, it has been used as a medicinal herb, considering its pharmacological properties and its recognized anti-inflammatory, antioxidant, and antimicrobial effects. Multiple studies have highlighted that the beneficial properties of Sumac extracts depend on the abundance of phytochemicals such as polyphenols, fatty acids, minerals, and fibers. Despite its wide use as a spice, the literature on Sumac effects on humans’ health and aging is still scarce. Considering its great nutraceutical potential, Sumac could be used to treat age-related diseases such as those in which the inflammatory process plays a crucial role in manifestation and progression. Thus, Sumac could be an interesting new insight in the biomedical field, especially in aging biomedicine.

Abstract
The clinical outcome of patients affected by Differentiated Thyroid Carcinoma (DTC) and an indeterminate response (IR) after initial therapy is not yet clear. IR includes three different sub-groups of patients: (1) IRTg+ group: Detectable thyroglobulin (Tg), regardless of antithyroglobulin antibodies (TgAb) presence or imaging studies; (2) IRTgAb+ group: Positive TgAb, regardless of Tg levels and nonspecific imaging findings; (3) IRImaging+ group: Nonspecific findings on neck ultrasonography or faint uptake in the thyroid bed on the whole-body scan, negative TgAb, and undetectable Tg. The main aim of this retrospective study was to investigate the dynamic evolution and prognostic role of these patients. From January 2010 to December 2017, 2176 patients who received radioiodine for DTC after total thyroidectomy were included. Two-hundred-eighty-eight patients had IR one year after therapy (187 TgAb+, 76 Tg+, 25 imaging+). After two years, 110 patients (38%) were reclassified as an excellent response and 5 (2%) as an incomplete response; after five years, 221 (77%) achieved an excellent response and 11 (4%) showed an incomplete response. One-year stimulated Tg and nodal disease at diagnosis may predict the final status of the disease. Progression-free survival was significantly shorter in IRTg+ than in IRTgAb+ and IRimaging+ groups. Considering Tg+ patients, a threshold of 3.3 ng/mL is best to predict prognosis.

Abstract
In the present paper, we have analysed the role of age and sex in the fatal outcome of COVID-19, as there are conflicting results in the literature. As such, we have answered three controversial questions regarding this aspect of the COVID-19 pandemic: (1) Have women been more resilient than men? (2) Did centenarians die less than the remaining older people? (3) Were older centenarians more resistant to SARS-CoV-2 than younger centenarians? The literature review demonstrated that: (1) it is women who are more resilient, in agreement with data showing that women live longer than men even during severe famines and epidemics; however, there are conflicting data regarding centenarian men; (2) centenarians overall did not die less than remaining older people, likely linked to their frailty; (3) in the first pandemic wave of 2020, centenarians > 101 years old (i.e., born before 1919), but not "younger centenarians", have been more resilient to COVID-19 and this may be related to the 1918 Spanish flu epidemic, although it is unclear what the mechanisms might be involved.

Abstract
Although mortality from COVID-19 progressively increases with age, there are controversial data in the literature on the probability of centenarians dying from COVID-19. Moreover, it has been claimed that men in their 90s and 100s are more resilient than women. To gain insight into this matter, we analysed, according to gender, mortality data during the first year of pandemic of Sicilian nonagenarians and centenarians. We used mortality data from the 2019 as a control. The crude excess mortality between the two years was calculated. Data on deaths of Sicilian 90 + years show that, in line with what is known about the different response to infections between the two genders, oldest females are more resilient to COVID-19 than males. Moreover, centenarians born before 1919, but not "younger centenarians", are resilient to COVID-19. This latter datum should be related to the 1918 Spanish flu epidemic, although the mechanisms involved are not clear.

Abstract
Several studies suggest that genetic variants that influence the onset, maintenance and resolution of the immune response might be fundamental in predicting the evolution of COVID-19. In the present paper, we analysed the distribution of GM allotypes (the genetic markers of immunoglobulin γ chains) in symptomatic and asymptomatic COVID-19 patients and in healthy controls, all born and residing in Sicily. Indeed, the role played by GM allotypes in immune responses and infection control is well known. Our findings show that the GM23 allotype is significantly reduced in healthy controls. Interestingly, in a previous study, Sicilians carrying the GM23 allotype were associated with the risk of developing a symptomatic Human Cytomegalovirus infection. However, a note of caution should be considered, due to the small sample size of patients and controls.

Abstract
Natural killer (NK) cells play a role in defence against viral infections by killing infected cells or by producing cytokines and interacting with adaptive immune cells. Killer immunoglobulin-like receptors (KIRs) regulate the activation of NK cells through their interaction with human leucocyte antigens (HLA). Ninety-six Sicilian patients positive to Human Immunodeficiency Virus-1 (HIV) and ninety-two Sicilian patients positive to SARS-CoV-2 were genotyped for KIRs and their HLA ligands. We also included fifty-six Sicilian patients with chronic hepatitis B (CHB) already recruited in our previous study. The aim of this study was to compare the distribution of KIR-HLA genes/groups of these three different infected populations with healthy Sicilian donors from the literature. We showed that the inhibitory KIR3DL1 gene and the KIR3DL1/HLA-B Bw4 pairing were more prevalent in individual CHB. At the same time, the frequency of HLA-C2 was increased in CHB compared to other groups. In contrast, the HLA-C1 ligand seems to have no contribution to CHB progression whereas it was significantly higher in COVID-19 and HIV-positive than healthy controls. These results suggest that specific KIR-HLA combinations can predict the outcome/susceptibility of these viral infections and allows to plan successful customized therapeutic strategies.

Abstract
Long-lived individuals (LLIs) are considered an ideal model to study healthy human aging. Blood fatty acid (FA) profile of a cohort of LLIs (90-111 years old, n = 49) from Sicily was compared to adults (18-64 years old, n = 69) and older adults (65-89 years old, n = 54) from the same area. Genetic variants in key enzymes related to FA biosynthesis and metabolism were also genotyped to investigate a potential genetic predisposition in determining the FA profile. Gas chromatography was employed to determine the FA profile, and genotyping was performed using high-resolution melt (HRM) analysis. Blood levels of total polyunsaturated FA (PUFA) and total trans-FA decreased with age, while the levels of saturated FA (SFA) remained unchanged. Interestingly, distinctively higher circulatory levels of monounsaturated FA (MUFA) in LLIs compared to adults and older adults were observed. In addition, among LLIs, rs174537 in the FA desaturase 1/2 (FADS1/2) gene was associated with linoleic acid (LA, 18:2n-6) and docosatetraenoic acid (DTA, 22:4n-6) levels, and the rs953413 in the elongase of very long FA 2 (ELOVL2) was associated with DTA levels. We further observed that rs174579 and rs174626 genotypes in FADS1/2 significantly affect delta-6 desaturase (D6D) activity. In conclusion, our results suggest that the LLIs have a different FA profile characterized by high MUFA content, which indicates reduced peroxidation while maintaining membrane fluidity.

Abstract
Population ageing is a great achievement of humanity, but it also represents a challenge that the Western world is currently facing, as ageing is associated with increased susceptibility to age-related inflammatory diseases. Therefore, it is necessary to fully understand the mechanisms of healthy ageing to prevent the harmful aspects of ageing. The study of long living individuals (LLIs) is a great model for trying to achieve this goal. Accordingly, the oxy-inflammatory status of Sicilian LLIs was reviewed in the present paper. Based on the reported data, anti-inflammatory and anti-oxidative stress strategies have been discussed, useful for delaying or avoiding the onset of age-related diseases, thus favouring a healthy ageing process.

Abstract
Vaccination, being able to prevent millions of cases of infectious diseases around the world every year, is the most effective medical intervention ever introduced. However, immunosenescence makes vaccines less effective in providing protection to older people. Although most studies explain that this is mainly due to the immunosenescence of T and B cells, the immunosenescence of innate immunity can also be a significant contributing factor. Alterations in function, number, subset, and distribution of blood neutrophils, monocytes, and natural killer and dendritic cells are detected in aging, thus potentially reducing the efficacy of vaccines in older individuals. In this paper, we focus on the immunosenescence of the innate blood immune cells. We discuss possible strategies to counteract the immunosenescence of innate immunity in order to improve the response to vaccination. In particular, we focus on advances in understanding the role and the development of new adjuvants, such as TLR agonists, considered a promising strategy to increase vaccination efficiency in older individuals.

Abstract
The number of people that are 65 years old or older has been increasing due to the improvement in medicine and public health. However, this trend is not accompanied by an increase in quality of life, and this population is vulnerable to most illnesses, especially to infectious diseases. Vaccination is the best strategy to prevent this fact, but older people present a less efficient response, as their immune system is weaker due mainly to a phenomenon known as immunosenescence. The adaptive immune system is constituted by two types of lymphocytes, T and B cells, and the function and fitness of these cell populations are affected during ageing. Here, we review the impact of ageing on T and B cells and discuss the approaches that have been described or proposed to modulate and reverse the decline of the ageing adaptive immune system.

Abstract
ABSTRACT An 80-year-old man with a history of prostate cancer, treated with radical prostatectomy and bilateral obturator nodal dissection, underwent an 18F-choline PET/CT because of biochemical recurrence. The scan revealed an intense focal uptake in the right testicle. A subsequent orchifunicumlectomy demonstrated the presence of a classic seminoma. At present, 18F-FDG PET/CT is useful for initial staging of testicular cancer and determining the viability of residual masses >3 cm after completion of treatment, especially in patients with seminoma.

Abstract
Using the murine monoclonal antibody (MoAb) B1.1 we have analyzed the immunochemical profile and the tissue distribution of a human melanoma associated antigen (MAA) carrying an epitope shared by the 180 kd CEA. Results of this study have demonstrated that the epitope expressed by the MAA is carried by a distinct set of molecules of 110-140 kd. Similarly to the 180 kd CEA molecules synthesized by carcinomas, the expression of the melanoma associated CEA like components (MA-CEA) is upregulated by IFN-α. The tissue distribution of MA-CEA is not restricted to malignant primary and metastatic melanocytic lesions but is found also at low levels in 64% of benign nevi. No circulating CEA was found in patients bearing widespread metastatic disease of MA-CEA positive lesions. Preliminary clinical evaluation of stage I melanoma patients bearing MoAb Bl. l positive lesions has not shown a significative prognostic association of this phenotypic marker with clinical course of the disease.

Abstract
AIM The aim of this paper to report the main clinical and immunopathological findings of our case series of 159 patients with dermatitis herpetiformis (DH). METHODS All DH patients that were diagnosed from 1995 to 2012 at the Section of Dermatology of the University of Florence were included in the study. Clinical data were collected for each patient. Moreover, histopathological examination on both the skin and the small bowel, direct immunofluorescence on perilesional skin as well as the search for anti-endomysium and anti-tissue transglutaminsase antibodies (tTG) were performed. RESULTS A total of 159 patients with a male predominance were enrolled. About 36% of the patients were below the age of 20. The most frequent clinical features seen in our DH patients were represented by figurate erythema, wheals, papules and scratching lesions, while the knees, elbows and buttocks were the most commonly involved sites. All the 22 patients that underwent a bowel biopsy showed the typical alterations found in celiac disease. Moreover, 100% of the patients showed granular IgA deposits at the papillary tips. Finally, anti-endomysium and anti-tTG antibodies were present in 90% and 96% of the patients, respectively. CONCLUSION We reported one of the largest case series of patients with DH from a single center. Our study confirmed most of the data from the Literature, and in particular the association of DH to histologically proven CD in all the biopsied cases. Another interesting finding of our study is the high prevalence of DH within pediatric patients, that is usually underreported.

Abstract
CONTEXT Previous observations showed a condition of low bone turnover and decreased osteoblast activity in both type 1 and 2 diabetes mellitus (DM1 and DM2). Sclerostin is a secreted Wnt antagonist produced by osteocytes that regulates osteoblast activity and thus bone turnover. Its levels increase with age and are regulated by PTH. OBJECTIVES The aim of the present study was to evaluate circulating sclerostin levels in patients with DM1 or DM2 with normal renal function and to analyze its relationship with PTH, 25-hydroxyvitamin D, and bone turnover markers. DESIGN, AND SETTING: This was a cross-sectional study conducted at a clinical research center. PARTICIPANTS Forty DM2 and 43 DM1 patients were studied and compared with a reference control group (n = 83). RESULTS In the overall cohort, sclerostin levels were higher in males than in females and significantly increased with age in both genders. The positive correlation between sclerostin and age was maintained in DM1 but not in DM2 patients. Moreover, sclerostin levels were higher in DM2 than in controls or DM1 patients, and this difference persisted when adjustments were made for age and body mass index. Consistent with previous clinical and experimental observations, sclerostin was negatively associated with PTH in nondiabetic patients (r = -0.30; P < 0.01), independently of age and gender. Conversely, an opposite but nonsignificant trend between PTH and sclerostin was observed in both DM1 (r = 0.26; P = 0.09) and DM2 (r = 0.32; P = 0.07) cohorts. CONCLUSIONS These findings suggest that sclerostin is increased in DM2. Moreover, the transcriptional suppression of sclerostin production by PTH might be impaired in both DM1 and DM2.

Abstract
Hospitalization for decompensated heart failure (HF) is associated with extraordinarily high rates of morbidity and mortality. Despite its high prevalence its pathophysiologic mechanisms and future risk stratification remain poorly defined and understudied. Several clinical Risk Scores to recognize high risk patients, has been purposed in the past but they are not able to completely identify future adverse events. In this sense, laboratory biomarkers play an important role in heart failure, but there remain unanswered questions regarding optimization of their use. One of the biggest hopes for utilizing biomarker testing is to determine the level of disease severity in a manner to triage medical decisions as well as to monitor their responses. Early diagnosis is very important for a better therapy optimization and outcome improving. Indeed, identification is often difficult because of symptoms unspecificity and the lack of gold standard protocol to make diagnosis. B-type natriuretic peptide is a useful tool to confirm or rule out heart failure. Therefore, BNP is one of the most best prognostic indicator in all stages of heart failure predicting outcome in both hospitalized and outpatients. Other neurohormonal, inflammatory and metabolic markers may add complementary information to that provided by currently available B-type natriuretic peptide assays. However all specific and general laboratory parameters cannot substitute to traditional clinical evaluation but could be used in adjunction for more precise evaluation and assessment. We reviewed traditional and some of emerging biomarkers of potential clinical application in HF setting.

Abstract
Objective: B-type natriuretic peptide (BNP) has been employed as a risk marker in patients with coronary artery disease (CAD) with ST elevation and non-ST elevation. It is not yet established if early BNP measurements provide additional information to troponin and electrocardiographic analysis in patients without ventricular enlargement and systolic dysfunction. Design: This study compared BNP levels in patients with stable angina (SA) and acute coronary syndromes with non-ST elevation in relation to angiographic lesions (NSTEMI-ACS). Moreover, the diagnostic utility of BNP was determined using the receiver operating characteristic curve. Patients: 280 patients with CAD without ST elevation and preserved systolic function were studied. BNP samples were measured in all recruited patients within 24 hours of hospitalization. Results: BNP values increased progressively with the severity of diagnosis: SA ( n = 85; 50.4 ± 50 pg/ml) NSTEMI-ACS ( n = 195; 283 ± 269 pg/ml; p < 0.0001). The analysis of BNP in relation to the number of involved vessels demonstrated significantly increased levels in patients with multivessel disease compared to patients with 1- or 2-vessel disease ( p < 0.001 and p < 0.003). Values of BNP >80 pg/ml were shown to be able to predict CAD severity and coronary vessel involvement (AUC = 0.80; p = 0.0001) with a sensitivity of 78% and a specificity of 72%. In multivariate analysis, BNP levels >80 pg/ml, CAD history, and ST deviation >2 mm were confirmed as independent predictors of CAD severity. Conclusions: Circulating BNP levels appear elevated in NSTEMI-ACS, without left ventricular systolic dysfunction. A BNP cut-off value of 80 pg/ml is a good predictor of CAD extension.

Abstract
Little is known about the effect of anemia correction with erythropoietin (EPO) on B-type natriuretic peptide (BNP) levels, NYHA class, and hospitalization rate. The aim of the study was to investigate, in patients with cardio-renal anemia syndrome, the effects of EPO on hemochrome and renal function parameters and BNP levels. We also analyzed the effect of EPO therapy on hospitalization rate and NYHA class after 12 months in comparison with a population undergoing to standard therapy. We performed a randomized double-blind controlled study of correction of the anemia with subcutaneous α (group A n = 13) or β (group B n = 14) EPO for 12 months in addition to standard therapy with oral iron in 27 subjects. Control group (n = 25 patients) received only oral iron. Significant increase in hemoglobin (Hb), hematocrit (Hct), and red blood cells (RBC) were revealed in EPO groups at 12 months; Hb, group A 12.3 ± 0.6; group B 11.7 ± 0.8; control group 10.6 ± 0.5 g/dl P < 0.0001; Hct group A 34.2 ± 2.3, group B 34 ± 2, control group 32.3 ± 1.8% P < 0.01; RBC, group A 3.9 ± 0.2, group B 3.8 ± 0.2, control group 3.3 ± 0.2, (P < 0.0001). Plasma BNP levels in EPO groups were significantly reduced after 12 months (group A: 335 ± 138 vs. group B: 449 ± 274 pg/ml control group 582 ± 209 pg/ml (P < 0.01). After 12 months of treatment, hospitalization rate and NYHA class were reduced in EPO groups with respect to control group (P < 0.05). Finally, an inverse correlation was observed between BNP and Hb levels in EPO Groups (r = -0.70 P < 0.001). EPO treatment reduces BNP levels and hospitalization rate in patients with cardio-renal anemia syndrome. The correction of anemia by EPO treatment appears able to improve clinical outcome in this subset of patients with heart failure.

Abstract
BACKGROUND Although anemia is frequently found in congestive heart failure (CHF), little is known about the effect of its correction with erythropoietin (EPO) on cardiac structure and function. OBJECTIVES The present study examines in patients with advanced CHF, chronic renal insufficiency, and anemia the effects of beta-EPO on left ventricular (LV) systolic diameter and volume (LVSD and LVSV), LV diastolic diameter and volume (LVDD and LVDV), LV mass, LV ejection fraction (LVEF), pulmonary artery pressure (PAP), and B-type natriuretic peptide (BNP) levels. METHODS Fifty-one consecutive subjects affected with advanced CHF and anemia were studied. We performed a randomized double-blind controlled study of correction of anemia with subcutaneous EPO for 4 months (group A, 26 patients) using saline as the placebo in the control group (group B, 25 patients). We then maintained the EPO treatment in the treated group for another 8 months. Both groups received oral iron throughout the total 12-month period. Echocardiographic evaluation, BNP levels, and hematological parameters are reported at 4 and 12 months. RESULTS The patients in group A during the double-blind phase (4 months) demonstrated an increase in LVEF and mild reduction in LVSD and LVSV with respect to baseline and to group B with no differences in PAP, LVDD, and LVDV. Over the 12-month period, the hemoglobin increased from 10.40.6 to 12.4 +/- 0.8 g/dL (P < .01) in group A but did not change in group B. Compared with group B, group A had lower LVDD, LVSD, LVDV, LVSV, LV mass, PAP, and BNP and higher LVEF. The serum creatinine and creatinine clearance remained unchanged in the 2 groups. CONCLUSIONS In anemic patients with CHF, correction of anemia with EPO and oral iron over 1 year lead to an improvement in LV systolic function, LV remodeling, BNP levels, and PAP compared with a control group in which only oral iron was used.

Abstract
BACKGROUND AND PURPOSE Diffusion and magnetization transfer (MT) techniques have been applied to the investigation with MR of epilepsy and have revealed changes in patients with or without abnormalities on MR imaging. We hypothesized that also in the coeliac disease (CD), epilepsy and cerebral calcifications (CEC) syndrome diffusion and MT techniques could reveal brain abnormalities undetected by MR imaging and tentatively correlated to epilepsy. MATERIALS AND METHODS Diffusion and MT weighted images were obtained in 10 patients with CEC, 8 patients with CD without epilepsy and 17 healthy volunteers. The whole brain apparent diffusion coefficient (ADC) and MT ratio (MTR) maps were analyzed with histograms and the Statistical Parametric Mapping 2 (SPM2) software. We employed the non-parametric Mann-Whitney U test to assess differences for ADC and MTR histogram metrics. Voxel by voxel comparison of the ADC and MTR maps was performed with 2 tails t-test corrected for multiple comparison. RESULTS A significantly higher whole brain ADC value as compared to healthy controls was observed in CEC (P = 0.006) and CD (P = 0.01) patients. SPM2 showed bilateral areas of significantly decreased MTR in the parietal and temporal subcortical white matter (WM) in the CEC patients. CONCLUSION Our study indicates that diffusion and MT techniques are also capable of revealing abnormalities undetected by MR imaging. In particular patients with CEC syndrome show an increase of the whole brain ADC histogram which is more pronounced than in patients with gluten intolerance. IN CEC patients, voxel-based analysis demonstrates a localized decrease of the MTR in the parieto-temporal subcortical WM.

Abstract
BACKGROUND Anemia is now recognized as being a common finding in CHF and is associated with increased mortality and morbidity. However, it is uncertain whether the anemia is actually causing the worse prognosis or is merely a marker of more severe cardiac disease. Previous intervention studies with subcutaneous (s.c.) beta-EPO in combination with iron have either been uncontrolled or case-controlled studies. We report a randomized, double-blind, placebo-controlled study of the combination of s.c. EPO and oral iron versus oral iron alone in patients with anemia and resistant CHF. OBJECTIVES The present study examines, in patients with advanced congestive heart failure (CHF) and anemia, the effects of beta-erythropoietin (EPO) and oral iron on the anemia and on cardiac and renal functional parameters. METHODS Forty consecutive subjects with moderate to severe CHF and anemia (hemoglobin [Hb] <11 g/dL) were studied. They were randomized to receive, in a double-blind fashion, either (a) (group A, the treatment group, 20 patients) s.c. beta-EPO for 3 months twice weekly, in addition to daily oral iron, or (b) (group B, the placebo group, 20 patients) normal saline in s.c. injections and daily oral iron. Two patients in group B were eventually excluded because of a fall of Hb <8 g/dL requiring transfusion, leaving 18 patients in group B. After the 3-months study, the group A patients were maintained on the same treatment for an additional 9 months, whereas in Group B, the placebo and oral iron were stopped. RESULTS In group A, after a mean of 3.5 +/- 0.8 months of treatment, there was a significant increase in Hb from 10.4 +/- 0.6 to 12.4 +/- 0.8 g/dL (P < .01); a significant improvement in New York Heart Association functional class from 3.5 +/- 0.6 to 2.8 +/- 0.5 (P < .05); a longer endurance time on exercise testing, from 5.8 +/- 2.2 to 7.8 +/- 2.5 minutes (P < .01); a greater distance walked on exercise testing, from 278 +/- 55 to 356 +/- 88 meters (P < .01); a significant increase in the peak oxygen consumption (VO2) from 12.8 +/- 2.8 to 15.1 +/- 2.8 mL/kg per minute (<.05); and the VO2 at the anaerobic threshold, from 9.2 +/- 2.0 to 13.2 +/- 3.6 mL/kg minute (P < .01). There was also a significant fall in plasma B-type natriuretic peptide levels from 568 +/- 320 to 271 +/- 120 pg/mL (P < .01), a significant reduction in serum creatinine (P < .01), and an increase in estimated creatinine clearance (P < .05). In group B, there were no significant changes in any of the above parameters over the study period. At the end of the 1-year study, the Hb was still higher in group A than group B, and the rate of hospital admissions/patients over the year averaged 0.8 +/- 0.2 in group A and 1.7 +/- 0.8 in group B (P < .01). CONCLUSIONS In anemic CHF patients, correction of anemia with EPO and oral iron leads to improvement in New York Heart Association status, measured exercise endurance, oxygen use during exercise, renal function and plasma B-type natriuretic peptide levels and reduces the need for hospitalization.

Abstract
Several emerging cardiac markers constitute strong predictors among patients with coronary artery disease. In particular, brain natriuretic peptide (BNP), troponin T (TnT), and C-reactive protein (CRP) are related to increased risk of recurrent ischemic events and death. However, little is known about the utility of these biomarkers in combination. This study examined risk assessment in patients with coronary artery disease and preserved systolic function. We studied 208 consecutive patients (138 men, 70 women) with stable angina, unstable angina, and non-Q-wave myocardial infarction whose plasma BNP, TnT, and CRP levels were measured at hospital admission. All recruited patients underwent echocardiographic examination, and selective coronary angiography was performed. After adjusting for clinical presentation, age, gender, and common risk factors, BNP was demonstrated as a strong predictor of heart failure (6 months, odds ratio [OR] 2.03, 95% confidence interval [CI] 1.24 to 2.9, p <0.01; 12 months, OR 2.65, 95% CI 1.69 to 3.5, p <0.001) and mortality at 3, 6, and 12 months (p <0.001). BNP was also significantly related to extent of coronary artery disease and left anterior descending artery involvement (p <0.01). Patients with a BNP level >80 pg/ml in all 3 groups had a significantly poorer prognosis with increased incidence of heart failure and death. CRP was related to recurrent ischemic events (infarct or recurrent angina, OR 1.4, 95% CI 1.14 to 2.08, p <0.01) and was associated with major cardiac revascularization at 12 months (OR 1.51, 95% CI 1.29 to 1.73, p <0.001). TnT demonstrated a mild correlation with recurrent infarct or angina at 12 months (OR 1.1, 95% CI 0.96 to 1.22, p <0.05) but appeared related to multivessel coronary artery disease (OR 1.47, 95% CI 1.05 to 1.99, p <0.01). In conclusion, BNP appears to be associated with a long-term increased risk of mortality and heart failure in patients with apparently mild risk. BNP is also associated with a larger extent and greater severity of myocardial ischemia. Early BNP measurement could provide incremental information to TnT and CRP, and it may be the strongest independent predictor of cardiac outcome in subjects without left ventricular dysfunction or enlargement.

Abstract
BACKGROUND Recently, it was shown that B-type natriuretic peptide levels are increased in patients with acute coronary syndromes. AIMS To assess the relation between B-type natriuretic peptide and ischemia in patients with stable and unstable angina pectoris with normal left ventricular function in relation to the extent of ischemia and response to revascularization. METHODS Fifty-nine consecutive patients were enrolled in the study, patients were divided into two groups: stable angina patients (group I, n=18), and unstable coronary patients (group II, n=41). Baseline characteristics were compared with 15 age-matched and sex-matched participants. B-type natriuretic peptide levels were measured at baseline and 3, 7 and 90 days after coronary revascularization in group I and II. RESULTS Patients with unstable angina pectoris had increased B-type natriuretic peptide levels compared with stable angina pectoris patients (B-type natriuretic peptide levels: controls 15.5+/-13 pg/ml, stable angina pectoris group 28.4+/-19 pg/ml, unstable angina pectoris group 104+/-81 pg/ml; P<0.01). A relationship between the number of affected coronary vessels and B-type natriuretic peptide was assessed (one-vessel 29.9+/-21 pg/ml, two-vessel 93.8+/-87 pg/ml, three-vessel 119+/-88 pg/ml; P<0.01). After revascularization, B-type natriuretic peptide levels decreased in groups I and II (25+/-20 vs. 39+/-28 pg/ml) and were similar after 90 days in percutaneous transluminal coronary angiograghy and in coronary artery bypass grafting groups (percutaneous transluminal coronary angiography 26+/-22 pg/ml, coronary artery bypass grafting 36+/-26 pg/ml; NS). CONCLUSIONS B-type natriuretic peptide levels increase in unstable angina pectoris patients and are linked to the extent of coronary disease in patients with normal left ventricular systolic function, and returned to baseline level after surgical or catheter revascularization.

OBJECTIVES The aim of the study was to investigate the occurence of anti-tissue transglutaminase antibodies (tTGA) in peripheral nerve disorders, and to correlate them with neurophysiologic findings and anti-glycolipid antibodies. MATERIALS AND METHODS We examined tTGA immunoglobulin-A serum level from 220 patients with polyneuropathy (acute inflammatory: n=90; chronic inflammatory: n=56; non-inflammatory: n=74) and 110 with motor neuron disease (MND). RESULTS Seven of the 330 neurologic patients (2.1%, six with polyneuropathy and one with MND) were positive for tTGA. Sixty-one of the 330 neurologic patients (18.4%) had slightly increased tTGA values compared with healthy controls. Increased tTGA values were associated with greater impairment of neurophysiologic findings, but not with the presence of anti-glycolipid antibodies. CONCLUSIONS We found a high prevalence of tTGA reactivity in patients with peripheral nerve disorders or MND. However, we were unable to demonstrate an increased risk of celiac disease in these diseases.

Abstract
UNLABELLED We examined the prevalence of PDB in Italy from radiological, scintigraphic, and biochemical surveys in two Italian towns. Prevalence rates varied from 0.7% to 2.4%, were higher in males than in females, and slightly differed between the two towns. Unlike previous studies in populations of British descent, no secular trend for a decreasing prevalence emerged. INTRODUCTION Clinical, radiological, and necropsy data from different countries suggested pronounced geographical variations in the prevalence of Paget's disease of bone (PDB). Despite the impact of the disease on the population, there are limited data on the prevalence of PDB in Italy. MATERIALS AND METHODS The objective of this study was to estimate the prevalence of PDB in the district of Siena (Central Italy) and Turin (Northern Italy) from radiological, biochemical, and scintigraphic surveys. We examined a sample of 1778 consecutive pelvic radiographs performed between 1999 and 2000 at the Hospital Radiology Unit in Siena and 6609 pelvic radiographs performed in 1986-1987, 1992-1993, and 1999-2002 from the Radiology Department of Molinette Hospital in Turin. In Siena, 7906 consecutive (99m)TC-MDP bone scans performed over a 4-year period (January 2000 to May 2004) were also screened for the presence of PDB, and the prevalence of elevated alkaline phosphatase (ALP) levels (>300 UI/liter) was estimated from 7449 computerized medical records over a 3-year period (January 2000 to February 2003). The finding of PDB on the pelvic radiograph and bone scan was based on standardized radiological criteria. RESULTS At the end of the radiological surveys, 16/1778 pelvic PDB cases (8 males and 8 females) were observed in Siena and 41/6609 (27 males and 14 females) in Turin. The crude prevalence of the disease was 0.89% in Siena and 0.62% in Turin. Given that pelvic involvement is commonly described in 60-90% of PDB patients, the estimated overall prevalence of PDB ranged from 1.0% to 1.5% in Siena and from 0.7% to 1.0% in Turin. No decrease in the prevalence of PDB was evident after comparison of prevalence rates from different periods. Biochemical analyses showed 296/7449 subjects with elevated ALP levels and normal liver enzymes, 87 of whom had confirmed diagnosis of PDB. The estimated prevalence of biochemical PDB was 1.5%. The scintigraphic survey showed a PDB prevalence of 194/7906 (2.4%), which was significantly higher than the radiological and biochemical estimates. CONCLUSIONS Our surveys suggest that PDB in Italy has an estimated prevalence of at least 1%, comparable with that observed in United States and other European countries, but lower than that described in Britain and New Zealand. No secular trend for a decreasing prevalence of PDB was observed.

Abstract
UNLABELLED This study examined the characteristics of 147 PDB cases from Italy. Our data showed a reduced clinical severity of PDB with respect to other populations and provided further support of the importance of environmental factors (rural area of residence and animal contact) in the pathogenesis of PDB. Familial aggregation was observed in 15% of cases. INTRODUCTION The etiology of Paget's disease of bone (PDB) remains unknown. Current evidence suggests that interactions among genetic or exogenous factors seem to be necessary for disease expression. Major epidemiological studies were performed in the United Kingdom and in other populations of British descent. To date, there are no reliable data on PDB characteristics among the Italian population, and its frequency in different areas of the country remains unknown. MATERIALS AND METHODS In an attempt to evaluate clinical characteristics, the proportion of familial cases and the influence of environmental features on the occurrence of the disease, we studied 147 consecutive PDB patients. For all subjects, a detailed medical history was obtained, and constitutional features were recorded. Characteristics of PDB patients were compared with those obtained from 323 consecutive non-Pagetic outpatient control subjects. RESULTS AND CONCLUSIONS Of the 147 PDB patients, 22 (15%) had at least one other family member affected, 19 (13%) reported one family member with suspected features of PDB, and 106 (72%) were classified as sporadic PDB. Even though we observed a reduced clinical severity of PDB with respect to other populations (mean number of affected sites, 2.2 +/- 1.6), we did not find any evidence of a decreased severity of the disease over time. We also found an association of PDB with animal contact (odds ratio [OR], 2.22; p < 0.0005) and a significant prevalence of PDB in rural versus urban districts (OR, 2.42; p < 0.0005). Osteoarthritis (45%), fractures (14%), hearing loss (14%), and valvular calcifications (15%) were the most observed complications. Interestingly, the geographical distribution of PDB showed a concentration of cases in rural areas of Campania and Tuscany. These areas may indicate local clustering of PDB cases in Italy, similar to that observed in other countries.

Abstract
Osteoporosis (OMIM166710) is a common skeletal disorder characterized by low bone mass and microarchitectural deterioration of bone tissue with increased susceptibility to fracture. Osteoporosis has a complex etiology and is considered a multifactorial polygenic disease in which genetic determinants are modulated by hormonal, environmental, and nutritional factors. Estrogens are known to play an important role in regulating bone homeostasis and preventing postmenopausal bone loss. They act through binding to two different estrogen receptors (ERs), ER alpha (OMIM133430) and ER beta (OMIM601663), which are members of the nuclear receptor superfamily of ligand-activated transcription factors. Different polymorphisms have been described in both the ER alpha and ER beta genes. Although a large number of association studies have been performed, the individual contribution of these polymorphisms to the pathogenesis of osteoporosis remains to be universally confirmed. Moreover, an important aim in future work will be to define their functional molecular consequences and their interaction with the environment in the causation of the osteoporotic phenotype. A further promising application of these polymorphisms comes from their pharmacogenomic implications, with the possibility of providing better guidance for therapeutic regimens, such as estrogen replacement therapy and selective ER modulators. At the moment, no recommendations for population-based screening can be made.

Abstract
The vectors of bluetongue virus are certain species of Culicoides biting midges, and in the Mediterranean area Culicoides imicola has long been considered to be the only field vector. In Sicily an entomological and serological surveillance programme has been in operation since the autumn of 2000, which has shown that the prevalence and abundance of C. imicola is lower than in many other Italian regions. Moreover, in 2002, there were outbreaks of bluetongue in the absence of C. imicola, and in these regions bluetongue viral RNA was detected by means of a nested reverse-transcriptase PCR in wild-caught, non-blood-engorged, parous Culicoides pulicaris. Furthermore, bluetongue virus serotype 2 was isolated on five occasions from extracts of non-blood-engorged parous C. pulicaris by using embryonated hens eggs and BHK-21 cells as assay systems. These findings suggest that in parts of Italy and possibly in other areas of Europe, where C. imicola is absent or rare, C. pulicaris may act as a fully competent vector of bluetongue virus.

Abstract
BACKGROUND The spinocerebellar ataxias (SCAs) are clinically heterogeneous disorders caused by triplet repeat expansions in the sequence of specific disease genes. Spinocerebellar ataxia type 8 (SCA8), originally described in a family characterized by pure cerebellar ataxia with slow disease progression, presents with expansion of combined CTA/CTG repeats. OBJECTIVE To perform SCA8 repeat expansion analysis in a heterogeneous group of ataxic patients, to determine the prevalence of this mutation in our patients and establish the frequency of expanded CTA/CTG repeats in a large group of control subjects. PATIENTS One hundred sixty-seven patients affected by sporadic, autosomal dominant and recessive hereditary ataxia were clinically examined and analyzed for SCA8 expansion. We further studied 161 control subjects and 125 patients with psychiatric disorders. RESULTS We found abnormally expanded CTA/CTG repeats in 5 ataxic patients, 3 of them characterized by pure cerebellar ataxia. One patient had vitamin E deficiency and 1 patient with a sporadic case was affected by gluten ataxia. No evidence of expanded alleles was found in healthy control subjects and in patients with psychiatric disorders. CONCLUSIONS Our data support the evidence that CTG expansions may be linked to SCA8, since the pathogenic expansions have been found only among patients with genetically unidentified forms of hereditary and sporadic ataxia. Patients carrying expanded alleles present peculiar phenotypic features, thus suggesting that unknown additional factors could probably predispose to the disease.

Abstract
The study of the antiproliferative action of somatostatin (ss) is important not only to understand the regulation of neuroendocrine tumours that express receptors (sst), but also non-endocrine tumours which express these receptors. We previously demonstrated the presence of sst2 in a wide panel of cell lines from human neuroblastoma. Although hypotheses have been put forward that treatment with ss or its analogs may be beneficial in oncological patients, this does not appear to be the case in neuroblastoma; patients with high sst2 levels (who are therefore sensitive to ss treatment) have per se a relatively positive outcome. Therefore, adjuvant treatment with ss is not necessary. Viceversa, patients with a poor prognosis are essentially characterized by a low expression of sst2 (and therefore are insensitive to a therapy with ss). In these patients adjuvant treatment with ss might be indicated, but would have little chance of success. Although the majority of neuroendocrine tumours expresses sst2, pancreas and prostate cancer express sst1 but not sst2, and are therefore insensitive to octreotide treatment which binds preferentially to sst2. Tumours like colorectal carcinoma and breast cancer also express sst2 in their more favourable forms. However, the concentration of sst2 in colorectal cancer is similar, if not lower than that in the surrounding normal tissue. Therefore, the probability of successful adjuvant therapy with ss is relatively low. In breast cancer, it is possible that sensitivity to estrogens may have a positive influence on the expression of sst2. This might justify clinical trials with ss in breast cancer.

Abstract
The repair of gastric ulcers requires the reconstitution of epithelial structures and the underlying connective tissue, including vessels and muscle layers. Several growth factors have been implicated in this process, since they are able to regulate important cell functions, such as cell proliferation, migration, differentiation, secretion, and degradation of extracellular matrix, all of which are essential during tissue healing. Epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), hepatocyte growth factor (HGF), and trefoil factors (TFFs) are mainly involved in the reconstitution of the epithelial structures. Platelet derived growth factor (PDGF), basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), and transforming growth factor-beta (TGF-beta) play a major role in the reconstitution of connective tissue, including vessels and smooth muscle cells, and provide the extracellular matrix substrate for cell migration and differentiation. The expression of these growth factors and their receptors is increased during ulcer healing and, in some cases, intracellular signaling related to receptor binding and transduction has been demonstrated. EGF, TGF-alpha and TFFs are normally present either in the gastric juice or in the mucosa, and may exert their effects immediately after damage, before newly synthesized EGF and TFFs are released from the ulcer margin. The inhibition of their effects by neutralizing antibodies may result in delayed ulcer healing, while the administration of recombinant or natural analogues may improve ulcer repair. In this review, we will summarize the basic molecular characteristics of some of these growth factors, and will discuss available evidence supporting their role in the ulcer repair process.

Abstract
We designed long-term in vivo experiments to study rabbit urethral regeneration and remodelling over a hyaluronan biodegradable prosthesis. Seven months after the resection of a 1.5-cm-long tract of the urethra and its substitution with the prosthesis, radiological analysis showed the disappearance of the implant and the re-establishment of urethral continuity along the transmural defect. The regenerated tissue remodelled around the implant and exhibited good distensibility under pressure. Histological evaluation showed that the neo-urethra was lined with transitional epithelium and the stroma contained abundant elastic fibres. An examination of the pattern of the major cytoskeletal and cytocontractile proteins of smooth muscle cells and fibroblasts was able to distinguish fibroblasts from smooth muscle cells and myofibroblasts in the neo-urethra. These experiments provide evidence for the potential, successful use of biocompatible/bioresorbable devices for reconstructive surgery of the urethra.

Abstract
We investigated the outcome of reconstructive surgery of the urethra through guides composed of a novel biodegradable and highly biocompatible polymer, Hyaff-11. A tract of about 1.5 cm of the rabbit pendulous urethra was totally resected and replaced by a Hyaff-11 tubular graft. Eleven animals were analysed at each of the time points ranging from 7 days to 4 weeks following surgery. Histological and radiological evaluation showed a satisfactory remodelling of the neo-urethra around the implant. The regenerated connective tissue connected both urethral stumps within the first 7 days. On postoperative week 3, the Hyaff-11 guide had disappeared. At the 4-week time point the retrograde urethrogram showed a good distensibility of the neourethra. The regenerated stroma consisted of fibroblastic cells, and collagenous and elastic fibres. The neo-epithelium was pluristratified and exhibited cells of the cuboidal type.
