Abstract
The purpose of this study is to assess the feasibility and the perioperative outcomes of laparoscopic gynecological surgery in regional anesthesia (RA) from the point of view of the surgeon, anesthesiologist and patient. This is a prospective cohort study comprising sixty-six women planned to undergo gynecologic laparoscopy surgery for benign pathology at tertiary care gynecolgical center of the University Federico II of Naples. Women were assigned, according to their preference, to either RA (Group A) or general anesthesia (GA) (Group B). Surgical, anesthesiologic and postoperative recovery data were recorded. Postoperative pain was considered as the primary outcome. Secondary outcomes included mobilization, length of hospital stay, global surgeons and patient satisfaction, intraoperative pain assessment in Group A. Immediate postoperative pain was significantly lower in Group A 0 vs 2 (p < 0.001), with no significant differences at 24 h. The secondary outcome demonstrated early patient’s mobilization (p < 0.001) as well as early discharge (p < 0.001) and greater patient’s satisfaction for the Group A. In these patients, a maximum pain score of 3 points out of 5 was recorded through the entire surgery. RA showed to decrease the impact of surgical stress and to guarantee a quicker recovery without compromising surgical results. Although several surgical approaches can be employed to treat different conditions, RA technique could be a viable option for well-selected patients affected by gynecological diseases.

Abstract
Background:The pathogenesis of pSS relies on a complex interplay between both innate and adaptive immune responses in which B cells play a pivotal role. Their chronic aberrant hyperactivation may drive clonal escape and consequent lymphomagenesis [1]. In the last few years, B cells have emerged as potential effector cells, able to release a wide range of cytokines that actively contribute to shape the microenvironment they act in. Recently, IL-40, a novel B cell associated cytokine encoded by an uncharacterized gene (C17orf99; chromosome 17 open reading frame 99) was described. Naïve B cells can express IL-40 at both tissue and peripheral level and the stimulation of B cells with IL-4 and TGF-β significantly increases IL-40 release. In addition, human B cells lymphomas are able to constitutively produce IL-40 [2]. Taking into account this emerging evidence and considering the well-known role of IL-4 and TGF-β in pSS pathogenesis, as well as the association with lymphomas, we decided to focus our attention on IL-40 in pSS patients.Objectives:The aim of the present study was to investigate IL-40 expression in the salivary glands of patients affected by pSS and pSS-associated non-Hodgkin’s lymphoma (NHL).Methods:Minor salivary gland biopsies were obtained from 22 patients with pSS and 12 patients with non-specific chronic sialoadenitis (nSCS), included as controls. Paraffine-embedded samples of parotid glands from patients with a previous diagnosis of pSS-associated NHL (n=10) were selected from the biopsy bank of the Pathology Unit of the Ospedale Cervello (Palermo, Italy). Quantitative gene expression analysis by TaqMan real-time PCR and immunohistochemistry (IHC) for IL-40, IL-4, TGF-β1 was performed on salivary glands from patients and controls. The cellular sources of IL-40 among infiltrating inflammatory cells were determined by fluorescence-activated cell sorting (FACS) analysis and immunofluorescence (IF). Serum IL-40 levels were measured by ELISA in both patients (n=10) and controls (n=9).Results:IL-40 was significantly increased at both protein and mRNA level in the inflamed salivary glands of patients with pSS where a positive strong correlation between the IL-40 mRNA levels and the focus score (FS) was evidenced. The expression of IL-40 in parotid glands of pSS-associated NHL was also markedly increased (Figure 1). IL-40 expression correlated with the presence of IL-4 and TGF-β; both cytokines were significantly increased in pSS at mRNA and protein level. Among infiltrating immune cells, CD19+ B cells resulted the major source of IL-40. However, we identified CD4+, CD8+ T cells and CD68+ macrophages as additional producers of IL-40 in both FACS and IF analysis. The ELISA test also showed a significant increase of serum IL-40 concentration in pSS patients (p value = 0.0190), compared to controls.Conclusion:Our preliminary results suggest that IL-40 may play a role in the pathogenesis of pSS and pSS-associated NHL. To the best of our knowledge, this is the first demonstration of the overexpression of this cytokine in salivary gland tissue and sera in pSS. Moreover, we demonstrated that IL-40 is produced by several cellular types, such as T cells and macrophages, and is not exclusively released by B cells. Further studies are necessary to clarify IL-40 pathways and functions in order to unravel IL-40 possible role in pSS development.References:[1]Mariette X, Criswell LA. Primary Sjogren’s Syndrome.

Abstract
Ubiquitin Proteasome System (UPS) is an adaptable and finely tuned system that sustains proteostasis network under a large variety of physiopathological conditions. Its dysregulation is often associated with the onset and progression of human diseases; hence, UPS modulation has emerged as a promising new avenue for the development of treatments of several relevant pathologies, such as cancer and neurodegeneration. The clinical interest in proteasome inhibition has considerably increased after the FDA approval in 2003 of bortezomib for relapsed/refractory multiple myeloma, which is now used in the front-line setting. Thereafter, two other proteasome inhibitors (carfilzomib and ixazomib), designed to overcome resistance to bortezomib, have been approved for treatment-experienced patients, and a variety of novel inhibitors are currently under preclinical and clinical investigation not only for haematological malignancies but also for solid tumours. However, since UPS collapse leads to toxic misfolded proteins accumulation, proteasome is attracting even more interest as a target for the care of neurodegenerative diseases, which are sustained by UPS impairment. Thus, conceptually, proteasome activation represents an innovative and largely unexplored target for drug development. According to a multidisciplinary approach, spanning from chemistry, biochemistry, molecular biology to pharmacology, this review will summarize the most recent available literature regarding different aspects of proteasome biology, focusing on structure, function and regulation of proteasome in physiological and pathological processes, mostly cancer and neurodegenerative diseases, connecting biochemical features and clinical studies of proteasome targeting drugs.

Abstract
Several lines of evidence point to a compromised proteostasis associated with a reduction of the Ubiquitin Proteasome System (UPS) activity in patients affected by Alzheimer's Disease (AD) and suggest that the amyloid β peptide (Aβ) is an important player in the game. Inspired also by many reports, underlining the presence of ubiquitin (Ub) in the amyloid plaques of AD brains, here we set out to test whether Ub may bind the Aβ peptide and have any effect on its clearance pathways. By using an integrated array of MALDI-TOF/UPLC-HRMS, fluorescence, NMR, SPR, Microscale Thermophoresis (MST) and molecular dynamics studies, we consistently demonstrated that Aβ40 binds Ub with a 1 : 1 stoichiometry and K d in the high micromolar range. In particular, we show that the N-terminal domain of the Aβ peptide (through residues D1, E3 and R5) interacts with the C-terminal tail of Ub (involving residues K63 and E64), inducing the central region of Aβ (14HQKLVFFAEDVGSNK28) to adopt a mixed α-helix/β-turn structure. ELISA assays, carried out in neuroblastoma cell lysates, suggest that Aβ competitively binds Ub also in the presence of the entire pool of cytosolic Ub binding proteins. Ub-bound Aβ has a lower tendency to aggregate into amyloid-like fibrils and is more slowly degraded by the Insulin Degrading Enzyme (IDE). Finally, we observe that the water soluble fragment Aβ1-16 significantly inhibits Ub chain growth reactions. These results evidence how the non-covalent interaction between Aβ peptides and Ub may have relevant effects on the regulation of the upstream events of the UPS and pave the way to future in vivo studies addressing the role played by Aβ peptide in the malfunction of proteome maintenance occurring in AD.

Abstract
The results of an endoscopic bioptic study of 16 cases of primary gastric malignant lymphoma are reported. Endoscopic observation suggested a diagnosis of malignant lymphoma in 50% of the cases, while directed biopsy gave a similar diagnosis in 75% of the cases. A correlation of the endoscopic and the histologic results gave a diagnostic reliability of 87.5% (14 of 16 cases). In order to obtain also in this group of neoplasms the diagnostic positivity already obtained in the epithelial forms, both improvement in the bioptic sampling technique and a better knowledge of the endoscopic morphology of the lesions must be achieved.

Abstract
INTRODUCTION Chronic diseases are the leading cause of death and disability in almost all over the world; in Europe causing over 9 million deaths per year according to WHO estimates. A promising health organization model for chronic disease management is represented by the Chronic Care Model (CCM). In the 12th district of the ASL Roma 2 since 4 years was implemented a CCM for the management of patients affected by diabetes and/or at high cardiovascular risk. OBJECTIVE Aim of this study is to evaluate the effectiveness of the Chronic Care Model (CCM) for the management of chronic disease in terms of mortality reduction, avoidable hospitalizations reduction and improvement of clinical parameters. MATERIALS AND METHODS A retrospective cohort study will involve patients of 12th district of the ASL Roma 2 affected by diabetes and at high cardiovascular risk assisted through the CCM. Their health outcomes will be compared with those of patients in the same clinical conditions, residents in the same district but not assisted with CCM. The sample will be composed by adults (> 18 years) with a diagnosis of diabetes mellitus type 2 (DM2) or metabolic syndrome and / or arterial hypertension (IT) and two or more risk factors. Outcomes will be mortality from all causes and from causes related to DM and IT, preventable hospitalizations as defined in the Prevention Quality Indicators (PQI) by the Agency for Healthcare Research and Quality, and 10 clinical parameters. The data sources will be the records of causes of death (RENCAM), the hospital discharge records (SDO) and information systems for primary healthcare. CONCLUSION Data from the experience of CCM in Tuscany seem promising especially in the evaluation of patient satisfaction and clinical outcomes particularly on cardiovascular and neurological complications and long-term mortality.

Abstract
Introduction Klippel–Feil syndrome is characterized by a congenital fusion of cervical vertebrae. Intracranial teratomas are nongerminomatous germ cell tumors and they account for 0.3 to 0.9% of all intracranial tumors. Teratomas with malignant transformation refer to lesions which give rise to malignant cancer of somatic type. The association between tumors of dermoid origin and Klippel–Feil malformation is extremely rare. Only 23 other cases have so far been reported, and only one case of dermoid tumor with areas of dedifferentiation on squamous cell carcinoma has been described. Case presentation We report the case of a 72-year-old white man with a 2-year history of gait and balance disturbances. A brain magnetic resonance imaging revealed a fourth ventricle neoplastic process with infiltrative features. He was operated through a suboccipital craniectomy with a C1 laminotomy and bilateral vertebral artery transposition. At 6-months follow-up, magnetic resonance imaging showed an early regrowth of the fourth ventricle tumor, with the same radiological features. Conclusions Patients with Klippel–Feil malformation could develop posterior fossa dermoid tumors. The malignant potential of such tumors must be considered and surgery is recommended. Particular attention must be focused on the histopathological analysis in order to identify possible foci of malignant transformation.

Abstract
Aim The aim of this article is to analyze the epidemiological and clinical features of migraine in a pediatric headache center. Methods A retrospective study was performed over six years. Hospital record databases were screened for the diagnosis of migraine with aura (MA) or without aura (MO), based on the ICHD-II criteria. Statistical analysis: Fisher’s test or Mann-Whitney U test, significance at p < 0.05. Results Migraine was diagnosed in 495 children (29.7% MA, 70.3% MO). The majority of diagnoses were made between ages 9 and 14 years. After stratification for age into five groups, we observed an increase of diagnoses in females, with a peak after the age of 15 years, and an increase of MA. In both groups, the attacks were usually severe, infrequent (<1–3/month) lasting <2 hours, and associated with nausea/vomiting, photophobia, phonophobia (more frequent in MO). Osmophobia was reported in 24.7% of the patients with MO. Dizziness was more frequent in patients with MA. Visual auras were the most common occurrence (87.1%). Confusional state was observed in 10.88% of the patients. A positive family history of headache was observed in >88% of the patients. Conclusion We describe the characteristics of pediatric migraine based on the ICHD-II criteria, showing a likely significant loss of diagnoses using the ICHD-III beta. The incidence of migraine increases with age. MO occurs more commonly and shows more frequent attacks and a higher prevalence of associated symptoms, in particular osmophobia. Although males are prevalent in the entire sample, the proportion of females is higher among patients with MA in all of the age groups. Phenotype and sexual prevalence of migraine acquire adult characteristics and become more frequent in females from the onset of puberty.

Abstract
To obtain an easy and prompt differential diagnosis between lower airways infections and acute radiation pneumonitis in chemoradiation lung cancer patients. From 303 patients treated, only patients with severe pulmonary symptoms were hospitalized. Clinical and radiation scores were calculated evaluating clinical, biohumoral, dosimetric parameters. Out of 36 patients hospitalized, infections and acute radiation pneumonitis were reported in 66.7% and 33.3%, respectively. Patients with clinical score ≥ 2 had an Odds Ratio of 3.4 (1.4-8.3; p = .006) to have infectious pneumonia, while radiation score was not predictive.

Abstract
Reactive astrogliosis, a feature of neuro-inflammation is induced by a number of endogenous mediators including cytokines. Despite interleukin-1 beta (IL-1β) stands out as the major inducer of this process, the underlying mechanism and its role on neuronal viability remain elusive. We investigated in human astrocytoma cells and the rat brain striatum, the role of the nuclear factor-kB (NF-kB) intracellular Ca(2+) concentration ([Ca(2+)]i) calmodulin (CaM) and extracellular regulated mitogen-activated protein kinases (ERK1/2) in IL-1β-induced expression of glial fibrillary acidic protein (GFAP) and neuronal apoptosis associated to a brain trauma. Cell data showed that IL-1β (1 ng/ml) increased NF-kB, pERK1/2 and GFAP expression. Nevertheless, further increase in IL-1β levels reversed progressively these responses. Preventing ERK1/2 activation with 1,4-diamino-2,3-dicyano-1,4-bis[2-aminophenylthiol]-butadiene antagonized IL-1β-induced GFAP expression while inhibiting selectively nuclear translocation of NF-kB with caffeic-acid phenethyl-ester down-regulated both ERK1/2 and GFAP expression induced by IL-1β. The GFAP response was also prevented by antagonizing selectively increase in [Ca(2+)]i, CaM activity or inducible nitric oxide synthase expression with respectively ryanodine plus 2-aminoethoxydiphenyl-borate, N-(6-aminohexyl)-5-chloro-1-naphthalensulfonamide hydrochloride and N-[(3-(aminomethyl)-phenyl]methyl]-ethanimidamide dihydrochloride. Data in vivo supported these findings and showed that GFAP expression induced by IL-1β (50 ng/ml) correlated with attenuated glial scar formation and reduced neuronal apoptosis. Our data identified the NF-kB/Ca(2+)-CaM/ERK signaling pathway as a novel in vivo key regulator of IL-1β-induced astrogliosis which may represent a potential target in neurodegeneration.

Abstract
BACKGROUND Endoscopic mucosal resection (EMR) is an effective therapeutic technique well-standardized worldwide for the treatment of gastrointestinal neoplasm limited to the mucosal layer. To date, no study has compared technical and clinical differences based on the number of EMRs performed per year. This study aimed to compare EMR technical success, complications, and clinical outcome between low-volume centers (LVCs) and high-volume centers (HVCs). A total of nine endoscopic centers were included in the study. METHODS This prospective study investigated consecutive patients with sessile polyps or flat colorectal lesions 1 cm or larger referred for EMR. RESULTS A total of 427 lesions were resected in 384 patients at nine endoscopic centers. Males accounted for 60.4% and females for 39.6% of the patients. Most of the EMRs (84.8%) were performed in HVCs and only 15.2% in LVCs. All the lesions were resected in only one session. Argon plasma coagulation was performed on the margins of piecemeal resection in 15.7% of the patients in HVCs only. Complete excision was achieved for 98.6% of the lesions in HVCs and 98.8% of the lesions in LVCs. The complication rate was 4.4% in HVCs and 4.6% in LVCs (p = 0.94). Delayed bleeding occurred in 2.5% of the HVC cases and 3.1% of the LVC cases. Perforation occurred in 1.9% of the HVC cases and 1.5% of the LVC cases (p = 1.00). Recurrences were experienced with 15% of the lesions: 15.5% in HVCs and 14% in LVCs (p = 0.79). CONCLUSIONS The study showed that EMR can be performed also in LVC.

Abstract
Micro RNAs (miRs) are small non-coding RNAs aberrantly expressed in human tumors. Here, we aim to identify miRs whose deregulated expression leads to the activation of oncogenic pathways in human gastric cancers (GCs). Thirty nine out of 123 tumoral and matched uninvolved peritumoral gastric specimens from three independent European subsets of patients were analyzed for the expression of 851 human miRs using Agilent Platform. The remaining 84 samples were used to validate miRs differentially expressed between tumoral and matched peritumoral specimens by qPCR. miR-204 falls into a group of eight miRs differentially expressed between tumoral and peritumoral samples. Downregulation of miR-204 has prognostic value and correlates with increased staining of Bcl-2 protein in tumoral specimens. Ectopic expression of miR-204 inhibited colony forming ability, migration and tumor engraftment of GC cells. miR-204 targeted Bcl-2 messenger RNA and increased responsiveness of GC cells to 5-fluorouracil and oxaliplatin treatment. Ectopic expression of Bcl-2 protein counteracted miR-204 pro-apoptotic activity in response to 5-fluorouracil. Altogether, these findings suggest that modulation of aberrant expression of miR-204, which in turn releases oncogenic Bcl-2 protein activity might hold promise for preventive and therapeutic strategies of GC.

Abstract
Erythropoietin (EPO)-mediated mitogenic and anti-apoptotic effects involve all the cells expressing functional receptors for EPO (EPOR), as demonstrated by in vitro and in vivo studies. EPO shows pleiotropic effects and acts as an endogenous mediator of adaptive tissue response to metabolic stress protecting tissues from different injuries. Recently, the EPO/EPOR complex has been identified in several neoplastic cell lines and solid tumours. In this study, the authors investigated the mast cells (MCs) number, distribution and their immunoreactivity for EPOR in normal, dysplastic and neoplastic canine mammary gland. The results showed that MCs were more numerous in displastic glands compared with normal and neoplastic glands. As far as the EPOR immunoreactivity is concerned, we did not observe MCs reaction on cancer, in contrast with previously published data where epithelium of neoplastic gland showed an increase in EPOR expression along with the neoplastic progression. Overall, our results might be suggestive for MCs role in oncogenesis and offer new insight regarding to the expression of EPOR in mammary gland cancer in dog.

Abstract
Primary mucinous carcinoma of the skin (MCS) is a rare neoplasia described for the first time by Lennox et al. in 1952 and formally reviewed by Mendoza and Helwing in 1971. It is an uncommon subtype of sweat gland tumor. MCS affects men (58,8%) more than women (41,2%). It tends to occur in more elderly individuals (average 62,6 years, range 8-87 years), although the disease has been reported in a patient as young as 8 years old. In the english Literature are described 100 case of MCS. MCS has a varied clinical onset, tipically presenting as an asymptomatic, slow-growning, painless, papular or nodular, subcutaneous or cutaneous, ranging from 5 mm to 120 mm. The lesion is frequently single and isolated red, pink, gray, blue or purple coulored. Telangiectasia may or not be present. The surface may be smooth, ulcerated or crusted. Local recurrence occurs frequently (29,4%) after conventional excision, but the rate of distant metastasis is low (9,6%). In fact this tumour is tipically avascular, a factor that help to explain its low rate of metastasis. In September 2007, a 69 year old white man was referred to our observation for the evaluation of a painless, superficial nodular mass in left cheek that had slowly grown over 1 year to 2x1,4 cm current measures. The lesion was excised. Microscopic examination revealed a mucinous cutaneous carcinoma of the skin. Investigations for a primary visceral malignancy, including CT total body and colonoscopy, were negative.

Abstract
BACKGROUND Erythropoietin (EPO), the main haematopoietic growth factor for the proliferation and differentiation of erythroid progenitor cells, is also known for its angiogenic and regenerative properties. MATERIALS AND METHODS In this study, we aimed to test the regenerative effects of EPO administration in an experimental model of Sea bass (Dicentrarchus labrax) subjected to amputation of the caudal fin. RESULTS Erythropoietin-treated fishes (3000 UI of human recombinant EPO-alpha immediately after cutting and after 15 days) showed an increased growth rate of their fins compared with those untreated (anova variance: P: 0.01 vs. P: 0.04). By analysing fin length at established times (15 and 30 days after cut), EPO-treated fishes always showed an increased length compared with untreated ones (T-15: 1.1 +/- 0.2 vs. 0.7 +/- 0.2 cm, P: 0.03; T-30: 1.9 +/- 0.3 vs. 1.2 +/- 0.2 cm, P: 0.01). Moreover, exogenous EPO administration induced an enormous increase in EPO-blood levels at each observation time (T-15: 2240 +/- 210 vs. 16.7 +/- 1.8 mU mL(-1), P < 0.001; T-30: 2340 +/- 190 vs. 17.1 +/- 1.9 mU mL(-1), P < 0.001), whereas these levels remained quite unmodified in untreated fishes. Immunochemical analyses performed by confocal laser scanning microscopic observations showed an increased expression of EPO-receptors and PECAM-1 (an endothelial surface marker of vessels sprout) in the regenerating tissue, whereas no signs of inflammation or fibrosis were recognisable. CONCLUSIONS All these findings confirm EPO as a new factor involved in regenerative processes, also suggesting a potential, future utility for new therapeutical applications in the field of human regenerative medicine.

Abstract
BACKGROUND Physiological needs during prolonged exercise are a potent stimulus for the hypothalamic-pituitary-adrenal (HPA) axis. Hence, athletes undergoing daily endurance training sessions may have frequent and prolonged phases of endogenous hypercortisolism. Since chronic glucocorticoids treatment leads to down-regulation of glucocorticoid receptor alpha (GR-alpha) mRNA expression, endurance training could lead to modulation of GR expression. AIM The aim of the study was to evaluate GR-alpha and GR-beta mRNA expressions in peripheral blood mononuclear cells and plasma cortisol, ACTH and cortisol binding globulin (CBG) concentrations at rest in subjects undergoing different training regimes. SUBJECTS AND METHODS Nine high trained (HT) swimmers (training volume: 21.6+/-1.7 hours/week in 10-12 sessions) were compared with two age-matched control groups represented by 8 low trained (LT) runners (training volume: 6.4+/-2.6 h/week in 3-5 sessions) and 9 untrained subjects. Expression of GR was determined by RT-PCR of total RNA. Hormone levels were determined by radioimmunoassay methods. RESULTS HT athletes showed 10 times less GR-alpha mRNA expression than the untrained subjects, while LT athletes exhibited values about twofold less than the untrained subjects. GR-beta mRNA expression was undetectable in all subjects. No differences were observed among the three groups in hormone levels. CONCLUSIONS GR- alpha mRNA expression is repressed in proportion to the amount and frequency of the stressful stimuli due to training. Hence, this down-regulation may be a consequence of the frequent and prolonged exposure to cortisol acute elevations induced by training. GR-beta did not play an important role in inducing the down-regulation of GR-alpha mRNA expression observed.

Abstract
Most inflammatory diseases show elevated levels of endothelin-1 (ET-1) probably due to an alteration in vascular structure and function with activation/accumulation of inflammatory cells. The ET receptors (ET(A), ET(B)) are widely expressed in all human vessels, consistent with the main role of ET-1 in maintaining physiological vascular tone. Previous findings have shown the expression on inflammatory cells such as neutrophils (PMNs) and macrophages (MØs) of ET-1 and endothelin-converting enzyme-1 (ECE-1) (the key enzyme in the biosynthesis of ET-1). Therefore the role of ET-1 cannot be related only to the vasoactivity. Our study was aimed to determine the expression and the cellular location of ET receptors in both human PMNs and MØs by the use of RT-PCR assay, Western blot analysis and immunocytological methods. Our results showed for the first time that PMNs and MØs clearly expressed ET(A) (mRNA and protein). Considering that the overproduction of ET-1 following endothelial dysfunction and inflammation, contributes to pathophysiological processes such as vascular hypertrophy, cell proliferation and fibrosis, our results suggest that PMNs and MØs can also play a key role in vascular dysfunctions via the possible formation of an autocrine loop between ET-1 and ET(A).

Abstract
Aims:(a) To evaluate tissue eosinophil density, location of eosinophil cytotoxic products, histopathological muscle changes and inflammatory cell types in different eosinophilia-associated myopathies that are clinicopathologically heterogeneous. (b) To determine the immunohistological range of tissue eosinophil density in non-eosinophilic inflammatory myopathies.Methods:Muscle biopsy specimens from seven patients with blood and/or tissue eosinophilia and clinicolaboratory myopathic signs (five chronic course myopathies, one subacute onset fasciitis/myositis, one acute myositis), and from 18 non-eosinophilic inflammatory myopathies, underwent routine staining, inflammatory infiltrate immunophenotyping, immunostaining for eosinophil major basic protein (MBP) and transmission electron microscopy examination. Eosinophil and total inflammatory cell counts were statistically analysed.Results:Histological examination showed occasional or no infiltrating eosinophils in all cases. MBP staining showed that tissue eosinophil density and percentages in eosinophilia-associated myopathies were significantly higher than in idiopathic myositides. Extracellular MBP diffusion, the hallmark of eosinophil cytotoxicity, was recurrent on sarcolemma and endothelium. Electron microscopy showed eosinophils close to sarcolemma, abundant mast cells, and capillary endothelial swelling. Immunostaining detected a higher mean eosinophil density in idiopathic myositides than previously assessed histologically.Conclusions:MBP immunohistology on skeletal muscle, previously performed only for acute eosinophilic polymyositis, suggests that eosinophil-mediated injury of muscle cells may occur in a wider spectrum of less aggressive eosinophilia-associated myopathies than previously thought. As conventional histology is likely to underestimate this leucocyte subset, MBP staining may be a useful tool in the analysis of tissue infiltration of eosinophils as a possible treatment target.

Abstract
BACKGROUND Thiopurines are the most commonly used immunomodulatory drugs in inflammatory bowel diseases. AIM To evaluate the use, the therapeutic and safety profiles of thiopurines in a large sample of IBD patients. METHODS We reviewed 3641 case histories of IBD patients. Thiopurines were prescribed in 582 patients (16.0%); the analysis was performed on the 553 (267 ulcerative colitis, 286 Crohn's disease) with exhaustive clinical data. RESULTS The main indications for treatment were steroid-dependence (328/553, 59.3%) and steroid-resistance (113/553, 20.7%). Thiopurines were started when CD were younger than UC patients (p<0.001) but earlier from diagnosis in UC than in CD patients (p=0.003). Efficacy was defined as optimal (258/553, 46.6%), partial (108/553, 19.5%), absent (85/553, 15.4%) and not assessable (102/553, 18.4%). Efficacy was independent of disease type, location/extension or duration and age at starting. Side effects were observed in 151/553 (27.3%) patients, leading to drug discontinuation in 101 (18.3%). 15 out of the 130 (11.5%) patients who took thiopurines for more than 4 years relapsed, more frequently in CD than in UC (OR=3.67 95% C.I. 0.98-13.69; p=0.053). CONCLUSIONS Thiopurines confirm their clinical usefulness and acceptable safety profile in managing complicated IBD patients. The majority of patients treated for longer than 4 years maintain response. No clinical and demographic predictive factors for efficacy and side effects were identified.

Abstract
Merkel cell carcinoma (MCC) is a rare malignant cutaneous neuroendocrine tumour with an aggressive behaviour and frequent regional lymph node and distant metastases. It mostly occurs in old patients and the commonest sites are the skin of the head, neck and the extremities. Typically, the primary tumour presents as a fast-growing, painless, reddish nodule with an iceberg-like effect, broadening in the depth. Although the pathogenesis of MCC remains largely unknown, ultraviolet radiation and immunosuppression are likely to play a significant pathogenetic role. The authors describe an unusual case of MCC clinically presenting as lymphedema on the right leg due to an inguinal lymphonodal metastasis. Although extensive investigations were performed the authors were unable to discover the cutaneous primary tumor. The authors examine the etiopathogenesis and hypothesis of this rare tumour and describe the clinical differential diagnosis. They suggest that clinical features together with imaging studies and morphological and immuno-histochemical findings are important for the correct diagnosis.

Abstract
We investigated lymphatic morphology and expression of endothelin (ET-1) axis molecules in human eyelids affected by an inflammatory state (chalazion) and an age-related degenerative condition (dermatochalasis). Lymphatics were immunohistologically detected by D2-40/LYVE-1 staining. Absorbing lymphatic vessels were localized in papillary dermis and around skin appendages with distinctive morphology. In chalazion, D2-40 reactive flattened lymphatic profiles were compressed by inflammatory infiltrate; in dermatochalasis, large fully opened lymphatics were observed, with a significantly wider total area (lymphatic lumina/200x field; p < 0.05). The lymphatic density (number/200x field) in the two groups was within the same range. Lymphatic dilation is possibly dependent on reduction and fragmentation of the dermal elastic network as well as of oxytalanic fibers in the papillary dermis of dermatochalasis, as shown by Weigert's reaction. Multifunctional peptide ET-1, involved in vasomotion, inflammation and connective proliferation, was faintly and discontinuously localized on lymphatics, as was its type A receptor. In contrast, the consistent expression of type B receptor indicates that lymphatic endothelium is a physiological target for ET-1, whose effects are modulated by multiple pathophysiological conditions. Thus, vasoactive factors play a role in the physiology of richly vascularized eyelids, and therefore, morphofunctional characterization of lymphatic vessels may be useful in suggesting treatment options.

Abstract
Endothelin-1 (ET-1), a potent vasoconstrictor peptide, is involved in several functions of eye pathophysiology, such as regulation of intraocular tension and retinal reactive vasoconstriction. As ET-1 pro-inflammatory and fibrosing activity is emerging in different fields of pathology, we investigated the expression of ET-1 and endothelin-converting enzyme-1 (ECE-1) in chalazia, granulomatous lesions of the eyelid. ET-1 and ECE-1 were analyzed by immunohistochemistry (IHC) in twenty surgically removed chalazia, with regard to expression in eyelid structures and inflammatory infiltrate. Phenotype of ET-1 expressing inflammatory cells was established by double immunofluorescence. The cellular localization of prepro-ET-1 (pp-ET-1) mRNA and ECE-1 mRNA was studied by nonisotopic in situ hybridization (ISH). Neutrophils (PMNs), macrophages and T-lymphocytes were scattered in stroma, around alveoli and grouped in lipogranulomas. PMNs, macrophages, basal epithelium of meibomian adenomers and central ducts immunostained for ET-1. ECE-1 protein was found in meibomian adenomers, conjunctival epithelium, tarsal mucous glands and in inflammatory cells. Hybridization signals for pp-ET-1 mRNA and ECE-1 mRNA were recognized in healthy and degenerating meibomian ducts, adenomers, inflammatory cells, as well as in vessel walls. ECE-1 mRNA was also present in conjunctival epithelium and Henle's crypts. Our findings suggest that the multifunctional peptide ET-1 may have a role in molecular genesis of tissue damage in chalazia. ET-1 cytokine activity is likely to support the migration of inflammatory cells and the setting of lipogranulomas; ET-1 stimulation might contribute to proliferation of fibroblasts and collagen synthesis. ET-1 upregulation on meibomian adenomers and ducts may further enhance granulomas formation by stimulating lipid release.

Abstract
STUDY DESIGN Case reports and review of the literature. OBJECTIVE Intramedullary spinal cord metastases (ISCMs) are rare type of central nervous system (CNS) involvement of systemic malignant tumors. Since the advent of new neuroradiological techniques, their detection have become increasingly diagnosed in recent years and, although somewhat controversial, surgical treatment has been considered a valid option. SETTING Neurosurgical Clinic, Department of Clinic Neuroscience, University of Palermo, Italy. METHOD The authors describe the case of a 61-year-old woman who was admitted presenting with progressive tetraplegia. Investigations revealed an intramedullary spinal cord lesion at the cervical level. Magnetic resonance imaging of the brain did not reveal other CNS metastatic lesions. RESULT Patient underwent surgical treatment. The tumor was resected and the patient's neurologic deficits slowly improved. Histological examination of the lesion showed the typical features of a colon carcinoma metastasis. Patient was referred for proper oncological treatment but, unfortunately, she died of disseminated disease within 2 months. CONCLUSION Although uncommon, spinal cord metastases should be considered in the differential diagnosis of ISCM in order to rationalize the decisional-making process and improve the quality of life for these patients.

Abstract
Enantiomeric pairs of 11 dansyl derivatives of alpha-amino acids were used as analytes in electrokinetic chromatography to test the ability as chiral selectors of two pure derivatives of beta-cyclodextrin: the ethylendiamine derivative in primary position (CDen) and a member of a new class of receptors, the cysteamine-bridged hemispherodextrin THCMH. The selectivity obtained by the presence of the hemispherodextrin, appears particularly promising as shown by the large values of resolution obtained. The importance of a detailed analysis of these data is discussed in terms of suggestions for a rational approach to separation science.

Abstract
Erythropoietin (EPO), already known as the stimulating hormone for erythropoiesis, has shown different and interesting pleiotropic actions. It does not only affect erythroid cells, but also myeloid cells, lymphocytes and megakaryocytes. This hormone can also enhance phagocytic function of the polymorphonuclear cells and reduce the activation of macrophages, thus modulating the inflammatory process.Moreover, hematopoietic and endothelial cells probably have the same cellular origin, and the discovery of erythropoietin receptors (EPO-R) also on mesangial and myocardial cells, smooth muscle fibrocells and neurons has prompted the study of the non-erythropoietic functions of this hormone.The interaction between EPO and VEGF may be of particular importance in neovascularization and wound healing. Different studies have demonstrated that EPO has an important direct hemodynamic and vasoactive action, which does not depend exclusively on any increase in hematocrit and viscosity. Moreover EPO showed protective effects on myocardial cells against apoptosis induced by ischemia/repefusion injury, but it could negatively affect pulmonary hypertension in patient with chronic cor pulmonale.This review aims to stress the importance of the increasing interest in EPO applications and the necessity of further studies to gain a deeper knowledge of this hormone and its pleiotropic and complex actions.

Abstract
AIMS To find a predictor of extraprostatic extension in clinically localized prostate cancer (PCa), pre-operative ultrasound-guided prostate needle biopsies and clinico-pathological data were reviewed. METHODS One hundred and eighty-three consecutive patients who underwent radical retropubic prostatectomy for clinical T1-T2 PCa and serum PSA <10 ng/ml were reviewed. Pre-operative biopsy was performed according to an extended protocol and whole-mount prostatectomy specimens were processed. The following biopsy variables were categorized to this analysis: Gleason score (< or =6, >6), TPC (< or =20%; >20%), GPC (< or =50%; >50%), cancer-positive cores (< or =2; >2), cancer-positive cores in both lateral portions (yes; no), PCa (monolateral; bilateral). RESULTS Only 60/183 specimens showed an organ-confined PCa; the remaining ones showed pT3a in 57 cases, pT3b in 11 and pT3 with positive surgical margins in 55. A locally advanced PCa was found in 60.2 and 76.8% of T1c and T2 clinical stage, respectively. The positive predictive value and negative predictive value of biopsy findings to predict a locally advanced PCa was 89.9 and 75%, respectively. All biopsy variables associations were statistically significant; however, among these variables (non-categorized), in multivariate logistic regression analysis, only GPC was significantly associated with pathologic stage (odds ratio estimate was 1.075, 95% CI: 1.053-1.098). CONCLUSIONS Quantitative histology, especially GPC, seems to be helpful for pre-operative staging of PCa in patients with T1c-T2 clinical stage and PSA < 10 ng/ml.
