Abstract
AIM The purpose of this prospective observational study was to analyze the role of Mib-1 immunostaining as a proliferation index in breast cancer. Correlations between Mib-1 expression and clinico-pathological characteristics as well as its prognostic value have been studied in a series of 432 node negative breast cancers. METHODS Mib-1 expression was evaluated by immunohistochemistry. Tumor sections from highly cellular invasive areas of cancer were stained by monoclonal antibody Mib-1 (Dako) and cells whose nuclei stained positive were counted in 10 randomly chosen HPFs and expressed as percentages of all epithelial cells. A minimum of 400 cells were counted. Correlation between Mib-1 staining and clinico-pathological factors was investigated by means of univariate and multivariate analyses. The prognostic impact on actuarial disease free (DFS) and overall survival (OS) was evaluated by univariate analysis using the log-rank test and by multivariate analysis using Cox regression model. RESULTS Tumors were considered as positive for Mib-1 expression when more than 15% of cells counted were stained. Mib-1 positivity was found in 190/432 cases and resulted in being significantly related to tumor grade, tumor size and absence of estrogen receptors at multivariate analysis. With a median follow-up of 66 months, Mib-1 positivity resulted in being the only independent predictor of OS (RR 2.92), and an independent predictor of DFS (RR 2.01) together with absence of estrogen receptors (RR 2.15). CONCLUSIONS Mib-1 index of proliferative activity correlates well to other established prognostic factors of breast cancer. Mib-1 index may improve the tailoring of adjuvant therapy in early breast cancer, and our experience adds evidence to its effectiveness as prognostic factor. Efforts to reach uniformity in the methodology and in the scoring system should be done to warrant a standardized procedure and make Mib-1 determination definitively reliable in the current clinical practice.

Abstract
Primary small-cell carcinoma (SmCC) of the stomach is a rare neoplasm with a poor prognosis and unclear histogenesis: to date, only 50 cases, including ours, have been reported in the literature. In the World Health Organization gastrointestinal tumours' classification, SmCC of the stomach has been recognized as an 'independent entity affecting the stomach'. In this paper, the authors present a clinical case and the surgical treatment of an adult with a SmCC of the stomach associated with gastric adenocarcinoma. After laparotomy, a large neoplasm with locoregional extension and multiple liver metastases were found. A palliative resection, subtotal gastrectomy, was performed, followed by systemic and intra-hepatic chemotherapy: computed tomography scan demonstrated a marked response, but the patient died 15 months after the operation. A review of the literature showed that the diagnosis of gastric SmCC is based on immunohistochemical findings. Our experience confirmed the high aggressiveness of this neoplasm, which is generally diagnosed in advanced stage and is unresponsive to chemotherapy, but the combined use of systemic and intra-hepatic chemotherapy shows an acceptable result in a palliative care perspective.

Abstract
We have investigated the activity of ITF2357, a novel hydroxamate histone deacetylase inhibitor, on multiple myeloma (MM) and acute myelogenous leukemia (AML) cells in vitro and in vivo. ITF2357 induced apoptosis in 8/9 MM and 6/7 AML cell lines, as well as 4/4 MM and 18/20 AML freshly isolated cases, with a mean IC(50) of 0.2 microM. ITF2357 activated the intrinsic apoptotic pathway, upregulated p21 and downmodulated Bcl-2 and Mcl-1. The drug induced hyperacetylation of histone H3, H4 and tubulin. When studied in more physiological conditions, ITF2357 was still strongly cytotoxic for the interleukin-6 (IL-6)-dependent MM cell line CMA-03, or for AML samples maximally stimulated by co-culture on mesenchymal stromal cells (MSCs), but not for the MSCs themselves. Interestingly, ITF2357 inhibited the production of IL-6, vascular endothelial growth factor (VEGF) and interferon-gamma by MSCs by 80-95%. Finally, the drug significantly prolonged survival of severe combined immunodeficient mice inoculated with the AML-PS in vivo passaged cell line already at the 10 mg/kg oral dose. These data demonstrate that ITF2357 has potent anti-neoplastic activity in vitro and in vivo through direct induction of leukemic cell apoptosis. Furthermore, the drug inhibits production of growth and angiogenic factors by bone marrow stromal cells, in particular IL-6 and VEGF.

Abstract
BACKGROUND Local recurrence occurs in 10%-20% of patients treated with breast-conserving surgery for stage I-II breast cancer. The aim of the present study was to investigate breast cancer local recurrence, potential risk factors, and prognostic impact. METHODS A total of 503 patients treated with breast-conserving surgery were included in the study. All patients underwent axillary dissection and postoperative radiotherapy, and all patients had negative margins at pathological examination. Median follow-up was 82 months. Local recurrence was classified as early when it occurred within 2 years from surgery. The risk factors for local recurrence and overall survival were estimated by univariate and multivariate analyses. RESULTS Forty-six cases (9.1%) of local recurrence were observed, 11 of which occurred within 24 months of surgery; the other 35, sometime later. Statistically significant risk factors for local recurrence were premenopausal status, peritumoral vascular invasion, multifocality, and absence of estrogen receptors. Independent negative prognostic factors for overall survival at 5 and 10 years were N stage, absence of estrogen receptors, and early time to recurrence. Overall survival at 10 years was 10.0% for patients with early recurrence, 87.5% for patients with late recurrence, and 87.9% for patients without recurrence. CONCLUSIONS None of the studied clinicopathological characteristics alone is a determinant for the choice of surgical treatment. Younger patients treated with breast-conserving surgery should receive aggressive postsurgical treatment and should be followed with an intensive follow-up program when metastatic axillary lymph nodes, negative estrogen receptors, or peritumoral vascular invasion are present.

Abstract
Meningococcal invasive disease is a life-threatening infection that affects mostly children and adolescents. The present study was performed during 2003-2005 to compare the phenotypic characteristics of meningococcal isolates from these two main groups at risk with those of isolates from other age groups to assess whether strategies for treatment and prevention implemented elsewhere can also be applied in Italy. The results showed that serogroup C meningococci were predominant, and that a dramatic increase in the circulation of strains with decreased susceptibility to penicillin was associated mainly with a prevalent phenotype C:2b:P1.5,2, which belongs to the hyper-virulent ST8/A4 cluster.

Abstract
A case of pseudoaneurysm of the splenic artery fistulized in the stomach and associated to a pancreatic pseudocyst is presented. A diabetic and alcoholist 40-year-old man was referred for gastrointestinal bleeding. Esophagogastro-duodenoscopy showed a tumefaction of the little gastric curve and a gastric bleeding fistula. A computed tomography demonstrated a pseudoaneurysm of the splenic artery fistulized in the stomach and associated to pancreatic pseudocyst. Marsupialization of the pancreatic pseudocyst, ligature of the splenic artery, splenectomy and closure of the gastric bleeding fistula were performed. There were no postoperative complications and the follow-up showed no other complications. Aneurysms and pseudoaneurysms of the splenic artery are very frequent, generally asymptomatic (70% of the cases) and in half of the cases they are occasionally diagnosticated. The bleeding of pseudoaneurysm for rupture or fistulization is a very rare and serious complication associated to a high percentage of mortality.

Abstract
In recent years many approaches to foreground extraction from images related to human movement have been presented. The foreground extraction represents a pre-processing procedure to be implemented in a system for capturing human movement in order to facilitate the tracking of anatomical landmarks on human bodies. In this work, an approach based on an unsupervised neural network has been studied: a Kohonen map has been designed to recognize and separate structures characterizing foreground and background. The proposed technique is fully automatic and its performance has been compared with those of two further approaches based on differences between foreground and background images. In order to quantify the segmentation quality, an already validated, objective, and automatic criterion has been used. The obtained results are adequate with the final aim of the application and show the feasibility of the proposed approach.

Abstract
AIM To evaluate the clinical implications of c-kit (CD117) expression in plasma cell myeloma (PCM). METHODS AND RESULTS We first evaluated the reliability of immunohistochemistry in assessing c-kit expression by comparing the results with those obtained by flow cytometry and gene expression arrays in 22 PCM and in 10 PCM cell lines. Immunohistochemical results showed a perfect concordance with those of flow cytometry; likewise, immunohistochemical and gene expression data were also concordant in all but one PCM and cell lines analysed. Then, we investigated the clinical implications of c-kit immunoreactivity in bone marrow biopsies of 85 PCM patients with a mean follow-up of 41 months. C-kit immunoreactivity was detected in 24 (28.2%) of the 85 cases and it was significantly associated with a high microvessel density, but not with traditional clinicopathological characteristics or with survival. CONCLUSIONS Our findings suggest that immunohistochemistry is a reliable indicator of c-kit gene expression and reinforce the notion that approximately one-third of PCM express high levels of c-kit. The lack of association with traditional clinicopathological parameters and patient survival suggests that c-kit expression may not be an adjunct in predicting the clinical course of the disease.

Abstract
BACKGROUND In head and neck squamous cell carcinoma, distinguishing second primary tumours and recurrences may help to orient clinical decisions concerning therapy. PATIENTS AND METHODS A panel of eight microsatellite markers was used to analyse the loss of heterozygosity and genomic instability in a selected group of 32 patients experiencing a recurrence after having undergone surgery for oral or oropharyngeal carcinoma, in order to establish the clonality and origin of the recurrence. RESULTS Twenty-three patients showed genetic changes in primary and/or relapsing tumour DNA: clonally-related patterns were detected in six cases, whereas the different patterns between paired tumours indicated the presence of a second primary tumour in 17 cases. None of the markers was informative in nine cases. CONCLUSION Our observations suggest that only a small proportion of patients have primary and secondary tumours developing from a single contiguous altered field (thus indicating a common clonal origin), whereas the metachronous tumour arises in unrelated fields in the majority of cases.

Abstract
Previous results suggest that GEM affects 5-fluorouracil (5-FU) metabolism and pharmacokinetics in cancer patients, while combined with oxaliplatin, levo-folinic acid, and 5-FU (GOLF regimen), at doses achievable in cancer patients, determines high cytotoxic and proapoptotic antitumour activity in colon cancer cells in vitro. On these bases we designed a phase I-II clinical trial testing the GOLF regimen in patients with metastatic colorectal carcinoma, who had received at least a prior line of chemotherapy. In total, 29 patients (20 males and nine females) enrolled in the study received every 2 weeks, gemcitabine (patients #1-3 received 600 mg m(-2); patients # 4-6 received 850 mg m(-2); while patients # 7-29 received 1000 mg m(-2)) on the day 1, levo-folinic acid (100 mg m(-2)) on the days 1 and 2; 5-fluorouracil (400 mg m(-2)) in bolus injection, followed by a 22-h continuous infusion (800 mg m(-2)) on the days 1 and 2, and oxaliplatin (85 mg m(-2)), 6 h after the 5-FU bolus on day 2. The most frequent side effect was grade I-II haematological toxicity. In total, 28 patients were evaluable for response: three achieved a complete response, nine a partial response, 10 had a stable disease, and six progressed. The average time to progression and overall survival of the patients was, respectively, 7.26 and 22 months. Our GOLF combination is well tolerated and seems promising for the treatment of advanced colorectal cancer.

Abstract
Reported here is a predominant clone of Neisseria meningitidis B:14:P1.13 that persisted over a 6-year period in the northernmost province of Italy, where it was responsible for a higher incidence of meningococcal disease compared to the rest of the country. Genetic relatedness of isolates was confirmed by multilocus sequence typing, pulsed-field gel electrophoresis and PorA variable region typing. All strains examined belonged to the ST44 complex/lineage III. Risk factors for infection were evaluated through a case-control study conducted with 21 cases and 63 age- and sex-matched controls. Risk factors for infection in the seven patients younger than 13 years were (i) residence in a rural area, (ii) exposure to passive smoke, and (iii) living in a home with rooms rented to tourists (all odds ratios infinite). The only risk factor for the older patients was previous influenza-like illness (odds ratio, 41.9; 95% confidence interval, 1.6-1068.9). Guidelines for the early treatment of patients and public information campaigns were successfully implemented to reduce disease transmission and the case fatality rate in the region.
