Abstract
BACKGROUND More than 50% of patients with colorectal cancer (CRC) present or develop hepatic metastases (HM). The intraoperative use of the Habib 4X® radio frequency probe device is safe in resetting HM and allows a one-stage resection of both CRC and HM with a similar mortality rate than a two-stage surgical treatment. METHODS After an exhaustive residential training at the reference center for hepato-biliary surgery of the Imperial College of London, we treated at our unit of general surgery 40 consecutive patients with CRC and HM with the one-stage resection, using the Habib 4X® intraoperative radiofrequency probe device to reset HM. RESULTS None of the 40 patients died during the intra-operatory and post-operatory periods, none presented liver failures during the postoperative course nor complication related to the Habib's resection procedure (e.g. bleeding, abscess, bile leak). The amount of intra-operative liver bleeding was minimal. New HM arose in 10 (25%) cases, with a mean disease-free interval of 13 months, but the hepatic tissue close to previous resections remained cancer-free. The 69.7% of patients were disease-free at month 24 of the post-operative follow-up and 5-year rate was about 70%. CONCLUSIONS The data suggest that surgeons well trained at a reference center for hepato-biliary surgery may perform with excellent results the one-stage CRC and HM resection with the Habib 4X® device even in a Unit of general surgery.

Abstract
BackgroundThe impact of the severe acute respiratory syndrome Coronavirus 2 disease (COVID-19) pandemic on people with systemic autoimmune rheumatic diseases (SARDs) remains to be fully established. It is unclear whether SARDs are an independent risk factor for COVID-19 infection and poor outcome.ObjectivesThe aim of our study is to assess the incidence and prognosis of test-proven SARS-CoV-2 infection during the first COVID-19 wave in a large population of SARD patients of the Lazio Italian region.MethodsWe retrospectively evaluated in a cohort of 4.716.119 subjects aged over 18 years and affiliated to the health system of the Lazio Italian Region, the incidence and 30-day outcomes of COVID-19 infection in 40.490 SARD pts and compared to the affiliated population as incidence rate ratio adjusted for demographics and comorbidities (adjIRR). SARD diagnosis and comorbidities were derived from medical administrative records using the Chronic Related Group classification system. Data on COVID-19 infection were derived from a dedicated regional digital network.ResultsThe risk of COVID-19 infection was increased in patients with Psoriatic Arthritis (adjIRR=1.21, 95% CI 1.10-1.33) and Undifferentiated Connective Tissue Disease (adjIRR=1.26, 95% CI 1.03-1.54). The risk of hospitalisation was higher in patients with Axial Spondylarthritis (adjIRR=2.16, 95% CI 1.45-3.22), and Systemic Vasculitis (adjIRR=1.81, 95% CI 1.07-3.06) while the risk of Intensive care unit admission was higher in Systemic Erythematous Lupus (adjIRR=3.67, 95% CI 1.52-8.83) and primary Sjögren Syndrome (adjIRR=4.13, 95% CI 1.71-9.96) patients. An increased COVID-19 mortality was reported in patients with Rheumatoid Arthritis (adjIRR=1.50, 95% CI 1.04-2.17), Systemic Erythematous Lupus (adjIRR=2.67, 95% CI 1.10-6.44), primary Sjögren Syndrome (adjIRR=2.51, 95% CI 1.12-5.62), and Scleroderma (adjIRR=4.60, 95% CI 2.06-10.29).ConclusionThe incidence of severe COVID-19 is not increased in the same percentage in SARDs. Each SARD presents a peculiar pattern in terms of increased risk of COVID-19 incidence, hospitalisation, intensive care unit admission and death, that is not linked to the immunosuppressive behaviour of the disease.Disclosure of InterestsNone declared

Abstract
BackgroundUltrasound (US)-guided minimally invasive Synovial Tissue (ST) biopsy serves as a safe and well tolerated procedure for basic and translational research on chronic inflammatory joint disease.Objectives(i) to assess the diagnostic value of the Krenn score (KSS) on ST samples obtained from US-guided biopsies in a large bio-samples dataset of patients with Psoriatic Arthritis (PsA) across different disease phases; (ii) to develop a multiparametric nomogram integrating clinical and histological characteristics enabling treatment response prediction in naïve to treatment PsA.Methods410 patients fulfilling the CASPAR criteria for PsA who underwent US-guided ST biopsy were enrolled. At baseline, patients were categorized based on their disease phase and treatment: n=207 naïve to DMARDs; n=101 resistant to c-DMARDs; n=48 resistant to b-DMARDs and n=54 in sustained clinical and ultrasound remission or in low disease activity (LDA) state (DAPSA ≤ 4 or among 4-14, respectively). Clinical, demographic, and immunological characteristics were recorded for each patient. All ST specimens were stained with H&E and classified by a pathologist, blinded to clinical characteristics, using the Krenn score to assess ST inflammation degree (1) implemented with the determination of lymphocytes, plasma cells, granulocytes and tissue oedema presence. Each naive to treatment PsA was treated according to the EULAR recommendations (2) and DAPSA remission rate at 6 months was recorded.ResultsConsidering the whole enrolled cohort, the distribution of KSS was significantly different among patients across the different PsA phases (ANOVA p<0.001). In particular, among the different phases, KSS was significantly higher in b-DMARDs resistant (p<0.0001) and c-DMARDs resistant (p<0.0001) compared to remission/LDA disease patients as well as naive to treatment PsA (p<0.0001). Interestingly, regardless to the disease phase, KSS of the biopsied joint directly correlated to disease activity in terms of DAPSA (r=0.476, p<0.001) and DAS28 scores (r=0.476, p<0.001). Considering the naïve to treatment PsA cohort, patients achieving DAPSA defined-LDA/remission had, before treatment, significantly lower KSS (p<0.001), lower rate of ST plasmacells presence (p<0.001) and shorter symptoms duration (p=0.01) as compared to naïve to treatment PsA not achieving this clinical outcome. Moreover, considering distinct clinical phenotype domains, naive to treatment PsA patients with concomitant dactylitis and skin disease were less likely to achieve DAPSA LDA/remission (p<0.001), regardless of treatment scheme. On logistic regression, at baseline, having a KSS <5 [OR: 5.30 (95%CI:2.21-12.74) p<0.001], absence of plasma cells ST infiltrate [OR: 3.87 (2.11-7.10 95%CI) p<0.001], concomitant dactylitis [OR: 2.55 (95%CI:1.24-5.25) p=0.01] and skin involvement [OR: 2.06 (95%CI:1.17-3.62) p=0.01] were independent factors associated with DAPSA score-LDA/remission achievement at 6 months. Finally, a multiparametric nomogram integrating baseline clinical and histological characteristics of naïve PsA enabling to predict up to 75% of probability to achieve DAPSA remission at 6 months was developed.ConclusionKSS is a reliable tool for synovitis assessment in PsA, being contingent on disease phases, related to disease burden and included within a treatment response predictive multiparametric nomogram in naïve PsA.References[1]Krenn V, et al.

Multidetector Computed Tomography (MDCT) Findings of Complications of Acute Cholecystitis. A Pictorial Essay. Tomography 2022; 8:1159-1171. [PMID: 35448729 PMCID: PMC9025054 DOI: 10.3390/tomography8020095] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 04/07/2022] [Accepted: 04/12/2022] [Indexed: 12/19/2022] Open
Abstract
Acute cholecystitis stands out as one of the most common surgical pathologies that should always be considered in a right-upper abdominal pain emergency. For this, the importance of a correct diagnosis is well described. However, it has been demonstrated that the simple combination of clinical (pain, Murphy’s sign) and laboratory (leukocytosis) parameters alone does not provide for ruling in or ruling out the diagnosis of this condition, unless accompanied by a radiological exam. For a long time, and still today, ultrasonography (US) is by far the first-to-proceed radiologic exam to perform, thanks to its rapidity and very high sensibility and specificity for the diagnosis of simple acute cholecystitis. However, acute cholecystitis can undergo some complications that US struggles to find. In addition to that, studies suggest that multidetector computed tomography (MDCT) is superior in showing complicated forms of cholecystitis in relation to sensibility and specificity and for its capability of reformatting multiplanar (MPR) reconstructions that give a more detailed view of complications. They have shown to be useful for a precise evaluation of vascular complications, the anatomy of the biliary tree, and the extension of inflammation to surrounding structures (i.e., colitis). Therefore, based also on our experience, in patients with atypical presentation, or in cases with high suspicion for a complicated form, a MDCT abdomen scan is performed. In this review, the principal findings are listed and described to create a CT classification of acute complications based on anatomical and topographic criteria.

Abstract
INTRODUCTION Kidney transplant recipients and patients on the waiting list for kidney transplant who acquire SARS-CoV-2 infection are at serious risk of developing severe COVID-19, with an increased risk of mortality for the their immunosuppressive state; other risk factors for mortality have been identified in some comorbidities such as obesity, diabetes, asthma and chronic lung disease. MATERIALS AND METHODS The COVID-19 pandemic has led to a sharp reduction in kidney transplants in most countries, mainly due to the concern of patients on the waiting list for their potential increased susceptibility to acquire SARS-CoV-2 infection in healthcare facilities and for the difficulties of transplant centers to ensure full activity as hospitals have had to focus most of their attention on COVID-19 patients. Indeed, while the infection curve continued its exponential rise, there was a vertical decline in kidney donation/transplant activity. CONCLUSION This review article focuses on the damage induced by SARS-CoV-2 infection on kidney and on the adverse effect of this pandemic on the entire kidney transplant sector.

Outcomes of Renal Stone Surgery Performed Either as Predonation or Ex Vivo Bench Procedure in Renal Grafts from Living Donors: A Systematic Review. BIOMED RESEARCH INTERNATIONAL 2020; 2020:6625882. [PMID: 33335926 PMCID: PMC7723480 DOI: 10.1155/2020/6625882] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 11/15/2020] [Accepted: 11/18/2020] [Indexed: 12/26/2022]
Abstract
AIMS We aimed to summarize available evidence about intraoperative and postoperative donors' and recipients' outcomes following stone surgery in renal grafts from living donors performed either before donation or as ex vivo bench surgery at the time of living-donor nephrectomy. METHODS A systematic review of PubMed, ISI Web of Knowledge, and Scopus databases was performed in September 2020. We included full papers that met the following criteria: original research, English language, human studies, and describing the results of stone surgery in renal grafts from living donors performed either before transplantation or as ex vivo bench surgery. RESULTS We identified 11 studies involving 106 patients aged between 22 and 72 years. Predonation and bench stone surgery was performed in 9 (8.5%) and 96 (90.6%) patients, respectively. Predonation stone surgery involved extracorporeal shock wave lithotripsy, retrograde intrarenal surgery, and percutaneous nephrolithotomy in 8, 1, and 1 patient, respectively. The overall success rate of predonation stone surgery was 78%, and the complication rate was 0%. Bench stone surgery involved ureteroscopy, pyelolithotomy, or a combination of both in 79 (82.3%), 10 (10.4%), and 7 (7.3%) cases, respectively, with an overall success rate of 95.8% and an overall complication rate of 9.37%. CONCLUSIONS Predonation and bench stone surgery in grafts from living donors represents efficacious and safe procedures. Further studies on wider series with a longer follow-up are required.

Abstract
Kidney transplantation is the surgical operation by which one of the two original kidneys is replaced with another healthy one donated by a compatible individual. In most cases, donors are recently deceased. There is the possibility of withdrawing a kidney from a consenting living subject. Usually, living donors are direct family members, but they could be volunteers completely unrelated to the recipient. A much-feared complication in case of kidney transplantation is the appearance of infections. These tend to arise due to immune-suppressor drugs administered as anti-rejection therapy. In this review, we describe the gastrointestinal complications that can occur in subjects undergoing renal transplantation associated with secondary pathogenic microorganisms or due to mechanical injury during surgery or to metabolic or organic toxicity correlated to anti-rejection therapy. Some of these complications may compromise the quality of life or pose a significant risk of mortality; fortunately, many of them can be prevented and treated without the stopping the immunosuppression, thus avoiding the patient being exposed to the risk of rejection episodes.

Abstract
Background:Cardiovascular complications are the leading cause of death in patients with psoriatic arthritis (PsA), but current strategies for reducing cardiovascular risk are still inadequate. Depression is a common comorbidity in PsA patients and it is recognized as an independent cardiovascular risk factor in the general population. Endothelial dysfunction, assessed as a reduction in brachial artery Flow Mediated Dilation (FMD), is a predictor of major cardiovascular events in high and low risk populations.Objectives:To investigate the relationship between endothelial function and depressive symptoms in a cohort of patients with PsA.Methods:Sixty consecutive patients with PsA, aged between 30 and 79 years, with no history of major cardiovascular events, were characterized for traditional cardiovascular risk factors and features of psoriatic disease. The risk of cardiovascular events according to traditional risk factors was calculated using the Framingham Risk Score (FRS) and the presence of depressive symptoms was defined through the Hospital Anxiety and Depression Scale (HDS) using the validated cut-off of 8. Endothelial function was assessed by FMD. Serum IL-6 was quantified by ELISA, IL-17 and TNF-α levels by Luminex method.Results:Patients had an average age of 52.1±11.0 years, 43.3% of them were male, 23.3% obese and 25.0% active smokers; 38.3%, 25.0% and 11.7% were treated for high blood pressure, dyslipidemia and diabetes mellitus, respectively. The 10-year risk of major cardiovascular events estimated by FRS was 10.4%. The mean duration of PsA was 9.4 years, 30.0% of patients were in minimal disease activity (MDA) and 61.7% and 46.7% were treated with conventional and biotechnological DMARDs, respectively. The mean HDS value was 6.9±3.2 and 43.4% of patients had significant depressive symptoms. The severity of depressive symptoms according to HDS correlated with disease activity according to DAPSA (r=0.449, p=0.001). The mean FMD was 7.8±3.8%, this value correlated inversely with age (r=-0.408,p<0.001), risk of major cardiovascular events according to FRS (r=-0.327, p=0.011) and severity of depressive symptoms according to HDS (r=-0.285, p=0.027). The correlation between FMD and serum IL-6, IL-17 and TNF-alpha levels was not statistically significant. In multivariate linear regression models, the relationship between FMD and HDS was significant also when corrected for age (β=-0.26, p=0.03, R2=0.23) and FRS normalized through logarithmic transformation (β=-0.32, p=0.009, R2=0.22).Conclusion:The degree of endothelial dysfunction quantified by FRS correlates with the severity of the depressive symptoms in patients with PsA, independently of the cardiovascular risk attributable to classical risk factors. The weak relationship between FRS and serum levels of IL-6, IL-17 and TNF-alpha suggests a role of factors independent of inflammation in the regulation of endothelial function in patients with PsA. Systematic research and treatment of depressive symptoms could contribute to a more complete stratification and a better management of cardiovascular risk in patients with PsA.Disclosure of Interests:Enrico De Lorenzis: None declared, Angela Di Giorgio: None declared, Gerlando Natalello: None declared, Antonio Nesci: None declared, Dario Bruno: None declared, Donatella Lucchetti: None declared, Giacomo Tanti: None declared, Clara Di Mario: None declared, Pietro Rubortone: None declared, Maria Rosaria Magurano: None declared, Barbara Tolusso: None declared, Angelo Santoliquido: None declared, Giusy Peluso: None declared, Elisa Gremese Consultant of: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer, Speakers bureau: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer

Abstract
Background:Secukinumab (SEC) is the first interleukin-17A inhibitor showing efficacy in both ankylosing spondylitis (AS) and psoriatic arthritis (PsA) in randomised trials, but real-life data are lacking.Objectives:In this prospective observational study, we evaluated the effectiveness and safety of SEC in patients with AS and PsA in a real-life setting.Methods:From September 2018 to September 2019, data were collected from 168 consecutive outpatients at baseline (T0) and at 6 (T6) and 12 months (T12) after starting SEC (39 AS, 23%; 129 PsA, 77%).Results:Significant improvement was seen at T6 and T12 for all clinical variables, including TJC, SJC, ESR, CRP, DAPSA, ASDAS-CRP, and BASDAI, as well as in patient-reported outcomes such as VAS-pain. By multivariable regression analysis, in AS patients high BASDAI at T0 correlated with diagnostic delay (R2=0.4; p=0.009) and peripheral joint involvement (R2=0.4; p=0.04). During follow-up, reduction of BASDAI positively correlated with high ESR (R2=0.65; p=0.04). ASDAS-CRP at T0 positively correlated with high ESR (R2=0.34; p=0.004). Reduction of ASDAS-CRP from T0 to T6 correlated with current smoking status (R2=0.42; p=0.0005). In PsA patients, reduction of DAPSA score from T0 to T12 negatively correlated with the presence of metabolic syndrome (R2=0.41; p= 0.0025). Retention rate showed good drug survival and an influence of female sex (Figure 1) in the survival curve in only AS patients, but no differences based on BMI, gender and lines of treatment were observed (Figure 2). SEC was well tolerated: Eleven patients discontinued treatment for non-severe adverse events.Conclusion:We demonstrated the effectiveness and safety of SEC in patients with AS and PsA in a real-life setting for the first time. No gender differences were observed; however, less clinical improvement was seen in smokers and in patients with metabolic syndromeReferences:No references.Disclosure of Interests:Maria Sole Chimenti: None declared, giulia lavinia fonti: None declared, Paola Conigliaro: None declared, flavia sunzini: None declared, Rossana Scrivo: None declared, luca navarini: None declared, paola triggianese: None declared, giusy peluso: None declared, Palma Scolieri: None declared, rosalba caccavale: None declared, Andrea Picchianti-Diamanti: None declared, erica de martino: None declared, simonetta salemi: None declared, domenico birra: None declared, Alessio Altobelli: None declared, marino paroli: None declared, Vincenzo Bruzzese: None declared, Bruno Laganà: None declared, Elisa Gremese Speakers bureau: Abbvie, BMS, Celgene, Jannsen, Lilly, MSD, Novartis, Pfizer, Sandoz, UCB, fabrizio conti Speakers bureau: BMS, Lilly, Abbvie, Pfizer, Sanofi, Antonella Afeltra: None declared, Roberto Perricone: None declared

Abstract
Background:Methotrexate (MTX) is a first-line treatment for psoriatic arthritis (PsA). Gastrointestinal intolerance (GI) to the drug is a common adverse event that limits its use and can be mediated by autonomic dysfunction or classical conditioning phenomena to repeated drug exposure. Anxiety and depression could promote these processes.Objectives:To assess the prevalence of GI to MTX and its association with anxiety and depression in PsA patients.Methods:One hundred unselected PsA patients in stable MTX treatment were characterized by disease characteristics, adherence to treatment by Morisky Medication Adherence Scale (MMAS-8) and comorbidity by Rheumatic Disease Comorbidity Index (RDCI). Depressive and anxious symptoms were assessed by Hospital Anxiety and Depression Scale (HADS). The presence and the severity of nausea, vomiting, abdominal pain and diarrhoea after administration (associative symptoms) and just before or even at the thought of taking MTX (anticipatory symptoms) were recorded.Results:Patients had a mean age of 56.9±12.0 years and a disease duration of 9.5 years (0.1-58.0 years). They were male, smokers and overweight in 40.0%, 20.0% and 65.0% of cases, respectively. The prevalence of both significant anxious and depressive symptoms was 42.0%. DAPSA showed remission, low disease activity (LDA), moderate disease activity (MDA) and high disease activity (HDA) in 24.0%, 41.0%, 32.0% and 3.0% of patients, respectively. MTX was taken orally by 15.0% of patients and associated with another conventional or biological DMARD in 14.0% and 35.0% of cases, respectively. Symptoms of GI to MTX were complained by 69.3% of patients. Specifically, the prevalence of nausea, diarrhea, vomiting and abdominal pain was 59.0%, 23.0%, 21.0% and 30.0% with associative pattern and 43.0%, 12.0%, 10.0% and 16.0% with anticipatory pattern, respectively. Patients with anxious symptoms experienced more frequently moderate to severe associative nausea (71.4% vs 50.0%, p=0.032) and abdominal pain (42.9% vs 20.7%, p=0.017), and anticipatory nausea (42.9% vs 19.0%, p=0.009), vomiting (14.3% vs 6.9%,p=0.046), and abdominal pain (26.2% vs 8.6%, p=0.018) than non-anxious patients. Patients with depressive symptoms more commonly had associative diarrhea (33.0% vs 15.5%, p=0.037), with no difference in the prevalence of anticipatory symptoms. The presence of associative and anticipatory nausea was associated with higher anxiety scores (p=0.006 and p=0.02 respectively) without differences in the depression score. Associative nausea characterized younger patients (p=0.001), female (p=0.02), with lower BMI (p=0.02) and treated with higher MTX doses (p=0.05). Anticipatory nausea was associated with a lower age (p=0.02), a lower BMI (p=0.005), a longer disease duration (p=0.028), a lower DAPSA (p=0.02), an higher MTX doses (p=0.02) and a lower comorbidity burden (p=0.03). The anticipatory and associative nausea determined lower compliance according to MMAS-8 (p=0.007 and p=0.001, respectively). An anxious profile characterized patients with moderate to severe associative nausea also in the logistic regression model corrected for age (≥65 years), gender, BMI (≥25 kg/m2) and MTX dose (≥0.2mg/kg/week) (OR 3.0, IC 1.1-8.4, p=0.036), and patients with anticipatory nausea also in the model corrected for age (≥65 years), gender, BMI (≥25 kg/m2) and MTX dose (≥0.2mg/kg/week) and disease duration (≥6 years) (OR 3.0, IC 1.1-8.0,p=0.027).Conclusion:Up to two-thirds of patients with PsA who have been treated with MTX experienced symptoms of GI, leading to reduced therapeutic adherence. Associative and anticipatory symptoms characterize patients with a specific clinical and psychological profile.Disclosure of Interests:Gerlando Natalello: None declared, Enrico De Lorenzis: None declared, Giacomo Tanti: None declared, Pietro Rubortone: None declared, Maria Rosaria Magurano: None declared, Giusy Peluso: None declared, Elisa Gremese Consultant of: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer, Speakers bureau: AbbVie, Bristol-Myers Squibb, Celgene, Eli Lilly, Janssen, Merck Sharp & Dohme, Novartis, Sanofi, UCB, Roche, Pfizer

Abstract
INTRODUCTION Kidney transplantation (KT) is the gold standard for treatment of patients with end- stage-renal disease. To expand the donor reserve, it is necessary to use marginal/suboptimal kidneys. METHODS We retrospectively evaluated the short/long-term outcome of 34 KT elderly patients who received allografts with vascular abnormalities (MRA group), in comparison with 34 KT patients who received a kidney with a single renal artery (SRA group) pair-matched by age, length of time on dialysis, comorbidity and donor age. RESULTS All participants completed the International Physical Activity Questionnaire at KT, and then 4, 8, and 12 weeks after transplantation. Our data indicate that kidney with vascular anatomical variants may be successfully transplanted, since the overall rate of surgical complications was 20.6% in the SRA group and 17.6% in the MRA group and that the 5-year survival rate after KT was 100% in both groups. CONCLUSIONS The data also underline that individualized physical activity programs induced similar excellent results in both groups, improving physical capacities, arterial pressure, lipid metabolism, insulin sensitivity, quality of life and physical and mental status.

Abstract
INTRODUCTION Wound complication frequently arises after kidney transplantation and its risk factors are well known. In a previous paper we analyzed these factors, and in this new retrospective study we evaluate the influence of lymphocele in the development of wound complications. PATIENTS AND METHODS From January 2000 to December 2018, 731 consecutive kidney transplants have been performed in our center. We have analyzed the incidence of wound complication and lymphocele and their risk factors. RESULTS Out of 731 kidney transplants, we have observed wound complications in 115 patients (15.7%) and lymphocele in 158 patients (21.7%). Of these, 70 patients developed both complications (9.5%), but 6 patients have been excluded because they were in therapy with mammalian target of rapamycin inhibitors. Twenty-nine patients (45.3%) presented a first level and 35 patients (54.7%) showed second level wound complications. Lymphocele was the only present factor in just 3 cases (4.6%). The other patients showed diabetes in 28 cases (43.7%), overweight/obesity in 38 (59.3%), delayed graft function in 17 (26.5%), and 60 years or more in 38 (57.8%). The association has been found in 30 out 64 patients treated with tacrolimus (46.8%) and in 34 with cyclosporine (53.1%); 40 patients did not receive muscular layer's reconstruction (62.5%). CONCLUSION Our experience shows that lymphocele alone is not a predisposing factor for wound dehiscence after kidney transplantation, and they often coexist because they share the same risk factors, the most important being obesity, diabetes and delayed graft function, older age, and surgical techniques. No relation has been observed with calcineurin inhibitor therapy.

Abstract
Objective: The aim of the study was to investigate endothelial function in treatment-naïve polymyalgia rheumatica (PMR) patients and its modification during steroid therapy, in relation to changes in clinical and laboratory parameters.Method: This prospective observational study involved patients with a new diagnosis of PMR according to provisional American College of Rheumatology/European League Against Rheumatism 2012 criteria, who were naïve to steroid therapy, and control subjects matched for age, gender, and comorbidities. All participants underwent clinical and vascular ultrasound evaluations at baseline and after 1, 3, 6, and 12 months of steroid therapy. For the study of endothelial function, we evaluated the brachial artery reactivity, which has emerged as the most well-established technique used in adults, by assessing flow-mediated dilatation (FMD), which measures the endothelium-dependent vasodilatation.Results: Sixteen newly diagnosed PMR patients were compared with a population of 16 matched controls. FMD values in all subjects showed an inverse correlation with the values of erythrocyte sedimentation rate and C-reactive protein. At baseline, the FMD of PMR patients was significantly lower than controls and remained significantly lower with respect to controls until the sixth month of therapy, despite a clinical improvement already being evident after 1 month of therapy.Conclusions: PMR is characterized by an important chronic subclinical inflammatory component. This pilot study demonstrates that affected patients show endothelial dysfunction that slowly responds to steroid therapy. Further studies are needed to investigate the clinical relevance of these observations and, in particular, to monitor the cardiovascular risk profile of PMR patients.

Abstract
Background There is currently no standard treatment for desmoid tumors (DTs) associated with familial polyposis coli (FAP). Familial adenomatous polyposis in DT patients is sometimes a life-threatening condition. Methods We enrolled all consecutive patients with FAP treated at Unit of General Surgery and Transplant, University of Naples Federico II and evaluated the incidence of DTs on FAP between 1996 and 2016. Results We observed 45 consecutive patients with FAP; of these 5 were DT-FAP-associated. All 5 cases with FAP were young women, age 25 to 65 years, previously treated by colectomy. Of these, 4 patients presented a parietal localization and had been treated with a wide surgical exeresis; one patient had an intra-abdominal, mesenteric tumor that was unresectable at laparotomy. We performed CT-guided drainage, ureteral stenting, medical therapy (sulindac+tamoxifene), and chemotherapy (dacarba-zine+doxorubicine).All patients were alive and underwent follow-ups for 5 years post-surgery; only 1 patient with parietal localization showed a local relapse after 2 years. Conclusions We propose a modulated approach to the single patient with FAP, with surgery as treatment of choice for parietal localization disease and integrating different kinds of therapies (surgery alone or associated with RT, CT) for the intra-abdominal tumor.

Abstract
BACKGROUND Patients on peritoneal dialysis treatment represent 15% of the global dialysis population. The major complication of peritoneal dialysis is catheter and peritoneal infection. Peritoneal dialysis patients who receive kidney transplants are at increased risk of infection because of immunosuppressive therapy. AIM The purpose of this study is to show our ideal timing to remove peritoneal catheter after kidney transplant, which gives adequate security on renal function recovery and reduction of septic risk. METHOD OF STUDY We analyzed the outcomes of 65 patients on peritoneal dialysis who underwent kidney transplant between 2000 and 2016. RESULTS In 61 cases there was an immediate graft functional recovery. In 4 cases there was a delayed graft function (DGF), and we performed a hemodialysis with temporary placement of a venous catheter. In all patients we removed peritoneal dialysis catheter 30 to 45 days after transplant. There has been 1 case of catheter infection, which was treated with antibiotic therapy. DISCUSSION Our average time to remove the peritoneal dialysis catheter was shorter than times in previous studies, between the 30th and 45th postoperative day. In the 4 cases in which there has been a DGF, we performed hemodialysis treatment to avoid, in the immediate postoperative period, direct insults to the peritoneum by local dialysis procedures. CONCLUSION Our experience show that the 30th to 45th postoperative day is a good time frame, better yet a good watershed between the safe removal of peritoneal catheter when patients have a stabilized renal function and the possibility of leaving it in situ, to resume peritoneal dialysis in case of persistent DGF.

Ethical Issues in the Use of Suboptimal Kidneys for Transplants: An Italian Point of View. Transplant Proc 2018; 51:106-110.

Abstract
The shortage of organs leads to the need for utilizing suboptimal kidneys for transplantation. The distinction between optimal, marginal, and suboptimal kidneys leads surgeons to face not only technical problems but also ethical and legal issues related to clinical advantages offered by the transplant of a nonstandard kidney and the acquisition of consent. Between 1999 and 2015, we performed 658 transplants, 49 (7.5%) using suboptimal kidneys. All patients were alive and with vital graft throughout follow-up. We did not encounter any major surgical complications. From a technical point of view, our experience and literature review confirm that transplant of suboptimal kidney leads to good clinical results but exposes patients to a increased risks of surgical complications. Therefore, these interventions must take place in hospitals fully prepared for this type of surgery and performed by experienced transplant surgeons with proper matching between organ and recipient. Considering the insufficient resources available, from an ethical and legal point of view, doctors play an essential role in optimizing the use of these kidneys by avoiding wastage of organs, ensuring that transplants are done in suitable patients, and that patients are fully informed and aware of the risks and benefits associated with the specific suboptimal kidney being transplanted. We believe that, in highly specialized centers, the number of suboptimal kidney transplants should be increased, as their use has shown good clinical results and carries fewer ethical issues compared with marginal kidneys. Further, suboptimal kidneys may also be proposed for use in young patients with end-stage renal disease.

Abstract
Neurodegenerative diseases (NDs) and brain tumors are severe, disabling, and incurable disorders that represent a critical problem regarding human suffering and the economic burden on the healthcare system. Because of the lack of effective therapies to treat NDs and brain tumors, the challenge for physicians is to discover new drugs to improve their patients' quality of life. In addition to risk factors such as genetics and environmental influences, increased cellular oxidative stress has been reported as one of the potential common etiologies in both disorders. Given their antioxidant and anti-inflammatory potential, dietary polyphenols are considered to be one of the most bioactive natural agents in chronic disease prevention and treatment. Despite the protective activity of polyphenols, their inefficient delivery systems and poor bioavailability strongly limit their use in medicine and functional food. A potential solution lies in polymeric nanoparticle-based polyphenol delivery systems that are able to enhance their absorption across the gastrointestinal tract, improve their bioavailability, and transport them to target organs. In the present manuscript, we provide an overview of the primary polyphenols used for ND and brain tumor prevention and treatment by focusing on recent findings, the principal factors limiting their application in clinical practice, and a promising delivery strategy to improve their bioavailability.

Abstract
The aims of the study were to determine (1) whether the presence of High blood pressure (HBP) states in the youth associate a steeper rate of age-related change in arterial geometrical and wall properties with respect to subjects with no previous cardiovascular risk factor (CRF) exposure, (2) in which parameters and in what magnitude, and (3) the existence of a gender-related difference in the impact of this condition on arterial properties. 300 individuals (mean/range: 15/4-29 years; 133 females) were included. Two groups were assembled: (1) Reference: nonprevious exposure to traditional CRF and (2) HBP: subjects with arterial hypertension and/or elevated blood pressure (BP) levels during the study. Additionally, HBP subjects were separated in BP-related subgroups. Measured parameters were (1) central (aortic) arterial BP and aortic pulse wave analysis parameters, (2) carotid and femoral artery local (pressure-strain elastic modulus) and regional (pulse wave velocity; PWV) stiffness, and (3) arterial diameters and carotid intima-media thickness (CIMT). Age-related changes in these parameters (absolute values and z-scores) were explored by obtaining simple linear regression models for each group. HBP presented a steeper rate of change (accelerated vascular aging; VA) for most of the parameters assessed, mainly in central (aortic) hemodynamics. VA increased as the HBP level got higher. Both males' and females' aging rates were affected by this condition, but females presented a more marked relative age-related increase with HBP exposure. HBP states in the youth gradually associate accelerated VA, with a progressive hemodynamic-structural-functional onset of damage, with females presenting a more marked relative HBP-associated arterial repercussion.

Abstract
Hyperspectral Raman images of human prostatic cells have been collected and analysed with several approaches to reveal differences among normal and tumor cell lines. The objective of the study was to test the potential of different chemometric methods in providing diagnostic responses. We focused our analysis on the ν(CH) region (2800-3100cm-1) owing to its optimal Signal-to-Noise ratio and because the main differences between the spectra of the two cell lines were observed in this frequency range. Multivariate analysis identified two principal components, which were positively recognized as due to the protein and the lipid fractions, respectively. The tumor cells exhibited a modified distribution of the cytoplasmatic lipid fraction (mainly localized alongside the cell boundary) which may result very useful for a preliminary screening. Principal Component analysis was found to provide high contrast and to be well suited for image-processing purposes. Self-Modelling Curve Resolution made available meaningful spectra and relative-concentration values; it revealed a 97% increase of the lipid fraction in the tumor cell with respect to the control. Finally, a univariate approach confirmed significant and reproducible differences between normal and tumor cells.

Abstract
Fluoride-releasing restorative dental materials can be beneficial to remineralize dentin and help prevent secondary caries. However, the effects of fluoride release from dental materials on the activity of dental pulp stem cells are not known. Here we investigate whether different fluoride release kinetics from dental resins supplemented with modified hydrotalcite (RK-F10) or fluoride-glass filler (RK-FG10) could influence the behavior of a human dental pulp stem cell subpopulation (STRO-1(+) cells) known for its ability to differentiate toward an odontoblast-like phenotype. The 2 resins, characterized by similar physicochemical properties and fluoride content, exhibited different long-term fluoride release kinetics. Our data demonstrate that long-term exposure of STRO-1(+) cells to a continuous release of a low amount of fluoride by RK-F10 increases their migratory response to transforming growth factor β1 (TGF-β1) and stromal cell-derived factor 1 (SDF-1), both important promoters of pulp stem cell recruitment. Moreover, the expression patterns of dentin sialoprotein (dspp), dentin matrix protein 1 (dmp1), osteocalcin (ocn), and matrix extracellular phosphoglycoprotein (mepe) indicate a complete odontoblast-like cell differentiation only when STRO-1(+) cells were cultured on RK-F10. On the contrary, RK-FG10, characterized by an initial fluoride release burst and reduced lifetime of the delivery, did not elicit any significant effect on both STRO-1(+) cell migration and differentiation. Taken together, our results highlight the importance of taking into account fluoride release kinetics in addition to fluoride concentration when designing new fluoride-restorative materials.

Abstract
Three-dimensional (3D) volumetric ultrasonography (US) is an interesting tool that could improve the traditional approach to musculoskeletal US in rheumatology, due to its virtual operator independence and reduced examination time. The aim of this study was to investigate the performance of 3DUS in the detection of bone erosions in hand and wrist joints of early rheumatoid arthritis (ERA) patients, with computed tomography (CT) as the reference method. Twenty ERA patients without erosions on standard radiography of hands and wrists underwent 3DUS and CT evaluation of eleven joints: radiocarpal, intercarpal, ulnocarpal, second to fifth metacarpo-phalangeal (MCP), and second to fifth proximal interphalangeal (PIP) joints of dominant hand. Eleven (55.0%) patients were erosive with CT and ten of them were erosive also at 3DUS evaluation. In five patients, 3DUS identified cortical breaks that were not erosions at CT evaluation. Considering CT as the gold standard to identify erosive patients, the 3DUS sensitivity, specificity, PPV, and NPV were 0.9, 0.55, 0.71, and 0.83, respectively. A total of 32 erosions were detected with CT, 15 of them were also observed at the same sites with 3DUS, whereas 17 were not seen on 3DUS evaluation. The majority of these 3DUS false-negative erosions were in the wrist joints. Furthermore, 18 erosions recorded by 3DUS were false positive. The majority of these 3DUS false-positive erosions were located at PIP joints. This study underlines the limits of 3DUS in detecting individual bone erosion, mostly at the wrist, despite the good sensitivity in identifying erosive patients.

Abstract
AIM Squamous cell carcinoma developed on a chronic pilonidal cyst. CASE REPORT Authors describe the case of a squamous cell carcinoma developed on a chronic pilonidal cyst in a 63- years-old patient with a 43 years history of recurrent pilonidal sinus disease. RESULTS The patient underwent incisional biopsy, staging with total body CT and, finally, radical surgery. After 30 months there were no evidence of recurrence. DISCUSSION Pilonidal sinus disease is a common disease that affects especially male subjects, obese and with excess of body hair. The complications that arise most frequently are cellulitis, abscess formation and developments of recurrences. Malignant transformation appears rather rare and is reported in the literature with a percentage that goes from 0.02% to 0.1%. CONCLUSIONS Authors recommend accurate inspection of the pilonidal area in all chronic and longstanding inflammatory lesions and possibly practice incisional biopsies to exclude malignant degeneration.

Abstract
Cellular senescence is the permanent arrest of cell cycle, physiologically related to aging and aging-associated diseases. Senescence is also recognized as a mechanism for limiting the regenerative potential of stem cells and to protect cells from cancer development. The senescence program is realized through autocrine/paracrine pathways based on the activation of a peculiar senescence-associated secretory phenotype (SASP). We show here that conditioned media (CM) of senescent mesenchymal stem cells (MSCs) contain a set of secreted factors that are able to induce a full senescence response in young cells. To delineate a hallmark of stem cells SASP, we have characterized the factors secreted by senescent MSC identifying insulin-like growth factor binding proteins 4 and 7 (IGFBP4 and IGFBP7) as key components needed for triggering senescence in young MSC. The pro-senescent effects of IGFBP4 and IGFBP7 are reversed by single or simultaneous immunodepletion of either proteins from senescent-CM. The blocking of IGFBP4/7 also reduces apoptosis and promotes cell growth, suggesting that they may have a pleiotropic effect on MSC biology. Furthermore, the simultaneous addition of rIGFBP4/7 increased senescence and induced apoptosis in young MSC. Collectively, these results suggest the occurrence of novel-secreted factors regulating MSC cellular senescence of potential importance for regenerative medicine and cancer therapy.

Methods: Genomic DNA was obtained from two cohorts of patients with RA (100 with early RA (ERA) and 114 with longstanding RA (LSRA)) and from 248 gender-matched controls from the same geographical area. Clinical and immunological characteristics were recorded for all the patients. Results: The percentage of the 2/2 genotype was higher in patients with ERA (27.0%), and in patients with LSRA (34.2%), than in controls (14.9%) (ERA: OR = 2.11 (95% CI 1.20 to 3.70) vs controls; LSRA: OR = 2.96 (95% CI 1.76 to 5.00) vs controls). A lower representation of allele *3 was present in patients with ERA (2.0%) than in controls (6.0%; OR = 0.32 (95% CI 0.11 to 0.91)). No significant associations were found between polymorphisms and autoantibodies positivity. Conclusion: The HS1,2A allele *2 associates with early and longstanding RA.

L-Carnitine in the treatment of fatigue in adult celiac disease patients: a pilot study. Dig Liver Dis 2007; 39:922-8. [PMID: 17693145 DOI: 10.1016/j.dld.2007.06.013] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2007] [Revised: 06/11/2007] [Accepted: 06/28/2007] [Indexed: 02/07/2023]
Abstract
BACKGROUND Fatigue is common in celiac disease. L-Carnitine blood levels are low in untreated celiac disease. L-Carnitine therapy was shown to improve muscular fatigue in several diseases. AIM To evaluate the effect of L-carnitine treatment in fatigue in adult celiac patients. METHODS Randomised double-blind versus placebo parallel study. Thirty celiac disease patients received 2 g daily, 180 days (L-carnitine group) and 30 were assigned to the placebo group (P group). The patients underwent clinical investigation and questionnaires (Scott-Huskisson Visual Analogue Scale for Asthenia, Verbal Scale for Asthenia, Zung Depression Scale, SF-36 Health Status Survey, EuroQoL). OCTN2 levels, the specific carnitine transporter, were detected in intestinal tissue. RESULTS Fatigue measured by Scott-Huskisson Visual Analogue Scale for Asthenia was significantly reduced in the L-carnitine group compared with the placebo group (p=0.0021). OCTN2 was decreased in celiac patients when compared to normal subjects (-134.67% in jejunum), and increased after diet in both celiac disease treatments. The other scales used did not show any significant difference between the two celiac disease treatment groups. CONCLUSION L-Carnitine therapy is safe and effective in ameliorating fatigue in celiac disease. Since L-carnitine is involved in muscle energy production its decreased absorption due to OCTN2 reduction might explain muscular symptoms in celiac disease patients. The diet-induced OCTN2 increase, improving carnitine absorption, might explain the L-carnitine treatment efficacy.

Abstract
OBJECTIVE To investigate the effect of pilocarpine on the salivary peptide and protein profile in patients with primary Sjögren's syndrome (SS) and to study the differences between patients with primary SS, patients with SS associated with other rheumatic diseases, and healthy control subjects. METHODS Saliva specimens were obtained from 9 primary SS patients, 9 secondary SS patients, and 10 healthy controls. Samples were analyzed for levels of 62 different salivary proteins using high-performance liquid chromatography coupled with mass spectrometry using a spectrometer equipped with an electrospray ionization source. In 6 of the primary SS patients, saliva was collected at 30 minutes, 60 minutes, and 24 hours after taking 5 mg of pilocarpine. RESULTS Before pilocarpine, approximately 60% of salivary proteins in samples from primary SS patients were not identifiable or showed lower levels than those in healthy controls. After 30-60 minutes following pilocarpine treatment, approximately one-third of the less represented proteins was found in a similar percentage of primary SS patients and controls. Almost all of the proteins that were detectable at lower levels in primary SS patients compared with controls reached levels similar to those in controls at 30-60 minutes after pilocarpine. The parotid gland proteins had the best response to pilocarpine. Primary SS patients were characterized by higher alpha-defensin 1 levels and by the presence of beta-defensin 2. Secondary SS patients showed an intermediate protein profile between that of the primary SS patients and the controls. CONCLUSION Pilocarpine partially restored the levels and numbers of identifiable proteins in saliva from patients with primary SS. Higher levels of alpha-defensin 1 and the presence of beta-defensin 2 in the saliva of patients with primary SS could be markers of oral inflammation in this patient group.

Abstract
AIM It has been established that antiphospholipid antibodies (aPL) are associated with recurrent abortions, but the pathophysiologic mechanisms that characterize thrombosis and recurrent pregnancy losses are still not clear.However, it is known that they are associated with the presence of antibodies directed against anionic phospholipids and putative cofactors. In this study the pathogenetic role of annexin A5, a potent anticoagulant cofactor protein for its anticoagulant property in recurrent abortions, was investigated. METHODS Endothelial cells of human umbilical veins ''EAHY2936 Line'' in culture were used, incubated with antiphospholipid anticardiolipin (ACA) antibodies purified from plasma of patients with recurrent abortions. The expression of annexin A5 on the cells with ACA was investigated by immunofluorescence and by confocal microscope. The negative control was also carried out: EAHY cells in cultivation medium without ACA. RESULTS Confocal analysis revealed a uniform distribution of annexin A5 on the cellular membranes in the negative control. Instead, in EAHY cells with ACA, the annexin A5 appears distributed in irregular manners on the cellular membranes (cytoplasmic and nuclear). CONCLUSION The results of an irregular ''cluster'' distribution of annexin A5 on the EAHY cells in presence of aPL, and in agreement with the literature, demonstrated that aPL, inhibiting annexin A5 ability to protect anionic phospholipid, promote the coagulation factors to diffuse laterally against phospholipids.

Abstract
Metabolic profiling is defined as the simultaneous assessment of substrate fluxes within and among the different pathways of metabolite synthesis and energy production under various physiological conditions. The use of stable-isotope tracers and the analysis of the distribution of labeled carbons in various intermediates, by both mass spectrometry and NMR spectroscopy, allow the role of several metabolic processes in cell growth and death to be defined. In the present paper we describe the metabolic profiling of Jurkat cells by isotopomer analysis using (13)C-NMR spectroscopy and [1,2-(13)C(2)]glucose as the stable-isotope tracer. The isotopomer analysis of the lactate, alanine, glutamate, proline, serine, glycine, malate and ribose-5-phosphate moiety of nucleotides has allowed original integrated information regarding the pentose phosphate pathway, TCA cycle, and amino acid metabolism in proliferating human leukemia T cells to be obtained. In particular, the contribution of the glucose-6-phosphate dehydrogenase and transketolase activities to phosphoribosyl-pyrophosphate synthesis was evaluated directly by the determination of isotopomers of the [1'-(13)C], [4',5'-(13)C(2)]ribosyl moiety of nucleotides. Furthermore, the relative contribution of the glycolysis and pentose cycle to lactate production was estimated via analysis of lactate isotopomers. Interestingly, pyruvate carboxylase and pyruvate dehydrogenase flux ratios measured by glutamate isotopomers and the production of isotopomers of several metabolites showed that the metabolic processes described could not take place simultaneously in the same macrocompartments (cells). Results revealed a heterogeneous metabolism in an asynchronous cell population that may be interpreted on the basis of different metabolic phenotypes of subpopulations in relation to different cell cycle phases.

Abstract
Recent studies suggest a close relationship between cell metabolism and apoptosis. We have evaluated changes in lipid metabolism on permeabilized hepatocytes treated with truncated Bid (tBid) in the presence of caspase inhibitors and exogenous cytochrome c. The measurement of beta-oxidation flux by labeled palmitate demonstrates that tBid inhibits beta-oxidation, thereby resulting in the accumulation of palmitoyl-coenzyme A (CoA) and depletion of acetyl-carnitine and acylcarnitines, which is pathognomonic for inhibition of carnitine palmitoyltransferase-1 (CPT-1). We also show that tBid decreases CPT-1 activity by a mechanism independent of both malonyl-CoA, the key inhibitory molecule of CPT-1, and Bak and/or Bax, but dependent on cardiolipin decrease. Overexpression of Bcl-2, which is able to interact with CPT-1, counteracts the effects exerted by tBid on beta-oxidation. The unexpected role of tBid in the regulation of lipid beta-oxidation suggests a model in which tBid-induced metabolic decline leads to the accumulation of toxic lipid metabolites such as palmitoyl-CoA, which might become participants in the apoptotic pathway.

Abstract
BACKGROUND AND AIMS Ulcerative colitis (UC) is characterised by refractory inflammatory ulceration and damage to the colon. The mechanisms underlying impaired healing have yet to be defined. As transglutaminase expression resulting in matrix protein cross linking is associated with increased wound healing in a rat model of colitis, we hypothesised that different types of transglutaminase might also play a role in UC. PATIENTS AND METHODS Endoscopic and histological indices were studied in 26 patients with UC (10 active and 16 inactive) and in 20 normal controls undergoing colonoscopy. Transglutaminase activity was evaluated in plasma (factor XIIIa) by a radioenzymatic method. Factor XIIIa, tissue and keratinocyte transglutaminase protein content, and mRNA expression in the colon were evaluated by western blot analysis and semiquantitative reverse transcription-polymerase chain reaction (RT-PCR), respectively. Colonic location of transglutaminases and their reaction products, the epsilon-(gamma-glutamyl)lysine bonds, was evaluated by immunohistochemistry using specific monoclonal antibodies. RESULTS Transglutaminase activity was significantly lower in the plasma of patients with active UC (4.2 (2.4) mU/ml; p<0.05 v controls) than in those with inactive UC and controls (10.6 (2.2) and 12.1 (1.7) mU/ml). As shown by western blot, protein levels of tissue transglutaminase and factor XIIIa were unchanged in active UC compared with inactive disease and controls, while the keratinocyte form was reduced in active UC. Tissue transglutaminase and factor XIIIa immunostaining was strongly present in damaged areas colocalising with isopeptide bonds. In contrast, the keratinocyte form was almost absent in active UC and localised in the upper part of the crypts in normal subjects. RT-PCR showed upregulation of tissue transglutaminase mRNA in active UC (320% compared with controls) while keratinocyte transglutaminase gene expression was downregulated in active UC. CONCLUSIONS The results of the present study support the concept that, in the damaged colon, transglutaminases are needed in response to chronic injury and underline the key role of these enzymes in mucosal healing.

Abstract
After about 10 years of experience, laparoscopic adrenalectomy has become the gold standard for the treatment of adrenal lesions. Here, we describe the presenting features, imaging methods, and current surgical approaches to diseases of the adrenal gland. There is general agreement on the suitability of the laparoscopic approach for benign adrenal lesions, but controversy exists about using laparoscopy for suspected adrenal malignancy, metastasis, and partial adrenalectomy. This article reviews the literature on laparoscopic adrenalectomy. In particular, we focus our attention on the new surgical approaches to the gland. We evaluate the indications, operative techniques, and tools for partial adrenalectomy, and we discuss new surgical strategies such as cryosurgery and radiofrequency ablation.

Abstract
Neural stem cells (NSCs) could be very useful for the "cell therapy" treatment of neurological disorders. For this reason basic studies aiming to well characterize the biology of NSCs are of great interest. We carried out a molecular and immunocytochemical analysis of EGF-responsive NSCs obtained from rat pups. After the initial growth of NSCs as floating neurospheres in EGF-containing medium, cells were plated on poly-L-ornithine-coated dishes either in the presence or absence of EGF. We followed cell differentiation and apoptosis for 21 days in vitro and analyzed the expression levels of some genes having a major role in these processes, such as pRB, pRB2/p130, p27, and p53. We observed that EGF impairs neuronal differentiation. Furthermore, in the absence of mitogens, apoptosis, which appeared to proceed through the "p53 network," was significantly lower than in the presence of EGF. The cyclin kinase inhibitor p27, while important for cell cycle exit, seemed dispensable for cell survival and differentiation.
