Abstract
INTRODUCTION Testing for mutations of epidermal growth factor receptor (EGFR) is crucial to identify non-small cell lung cancer (NSCLC) patients eligible for treatment with EGFR tyrosine kinase inhibitors (EGFR-TKIs); This study aims to describe EGFR-mutation testing, treatment patterns, and overall survival (OS) in localized NSCLC patients. MATERIALS AND METHODS Patients with localized (Stage IB-IIIA) NSCLC registered in the Norwegian Cancer Registry during 2010-2017 were followed from diagnosis until emigration, death, or end of study in 2018. The cohort was linked to data from the Norwegian Patient Registry, the Prescription Database, and the Cause of Death Registry. RESULTS Of 2367 patients identified with localized NSCLC, 52 % were females and median age at diagnosis was 69 years. Most (66 %) were treated with surgery, while 16 % received curatively-intended radiotherapy (RT). EGFR-mutation testing increased significantly from 58 to 84 % during the study period. Testing frequencies varied across regions and comorbidity levels. Nine-percent of tested patients were EGFR-mutation positive (EGFRm+), of whom 27 % were treated with EGFR-TKIs. There was no correlation between initial treatment with either surgery or RT and EGFR-TKI use. The 3-year OS did not vary considerably by EGFR-mutation testing, but EGFRm+ patients had a higher 3-year OS (78.8 %) than wild-type EGFR (EGFRwt) patients (65.9 %). DISCUSSION Although EGFR-mutation testing is increasingly being implemented in the early-stage setting in line with national recommendations, some patients are still not being tested for molecular markers as part of their diagnostic workup-a prerequisite for providing equal access to effective targeted treatments, such as EGFR-TKIs, to eligible patients.

Abstract
BACKGROUND Despite advances in treatment strategies and improved clinical outcomes, an unmet need remains for NSCLC patients. With an increased real-world knowledge of NSCLC, clinicians could offer patients optimal tailored treatment and disease management. In this retrospective cohort study, we describe patient characteristics, treatment patterns and modality, and survival in NSCLC patients diagnosed and treated at Aarhus University Hospital, Denmark. METHODS Data on Stage III NSCLC patients aged ≥18 years diagnosed 2010-2018 were obtained from a regional cancer database and linked to national registries for information on socioeconomic and vital status. Patients were stratified by planned treatment intention at diagnosis (curative/palliative). Treatment patterns and overall survival (OS) were estimated using time-to-event methods. RESULTS Broad patient and diseases characteristics and multiple treatment options demonstrated the heterogeneity of this patient cohort. Of 851 Stage III NSCLC patients, 599 (70%) and 252 (30%) were offered curative- and palliative-intended treatment, respectively, upon evaluation by a multidisciplinary team (MDT). The most frequent treatment modalities were CRT (n = 328; 55%) and RT (n = 97; 38%) in the curative and palliative setting, respectively. Age, disease stage, performance status and comorbidity were associated with curative-intended treatment initiation. Curative-intended treatment was associated with an improved OS of 14.6 months (median OS 24.4 months, 95% CI 21.1-27.6). Being offered curative-intended treatment and/or being diagnosed in the more contemporary study period (2016-2018) were significantly correlated with better OS (p < 0.001). CONCLUSION Stage III NSCLC is a heterogeneous disease as regards patient and clinical characteristics, multiple treatment options, and outcomes. Age, disease staging, performance status, and comorbidity, as well as MDT evaluation and matching treatment intent, are important determinants of curative-intended treatment. Notably, an NSCLC diagnosis in the more contemporary study period was statistically significantly associated with better OS.

Abstract
BACKGROUND Multiple sclerosis (MS) patients have an increased risk of infections, but few population-based studies have reported infections occurring in MS in the years immediately after diagnosis. OBJECTIVE To explore incident infections in MS, stratified by age and sex. METHODS In a Swedish population-based cohort study 6602 incident MS patients (aged ≥18 years), matched at diagnosis with 61,828 matched MS-free individuals were identified between 1st January 2008 and 31st December 2016, using national registers. Incidence rates (IR) and incidence rate ratios (IRR) with 95% CI were calculated for each outcome. RESULTS The IRRs were 2.54 (95% CI 2.28-2.83) for first serious infection and 1.61 (1.52-1.71) for first non-serious infection. Compared with MS-free individuals, MS patients had higher IRs for skin, respiratory/throat infections, pneumonia/influenza, bacterial, viral, and fungal infections, with the highest IRR observed for urinary tract/kidney infections (2.44; 2.24-2.66). The cumulative incidence for most of these infections was higher among MS patients than MS-free individuals, both 0 to <5 and 5 to <9 years after index date. CONCLUSION The burden of infections around the time of MS diagnosis and subsequent infection risk, underscore the need for careful considerations regarding the risk-benefit across different disease-modifying therapies.

Abstract
Established cell culture systems have failed to accurately recapitulate key features of terminal erythroid maturation, hampering our ability to in vitro model and treat diseases with impaired erythropoiesis such as myelodysplastic syndromes with ring sideroblasts (MDS-RS). We developed an efficient and robust three-dimensional (3D) scaffold culture model supporting terminal erythroid differentiation from both mononuclear (MNC) or CD34+-enriched primary bone marrow cells from healthy donors and MDS-RS patients. While CD34+ cells did not proliferate beyond two weeks in 2D suspension cultures, the 3D scaffolds supported CD34+ and MNC erythroid proliferation over four weeks demonstrating the importance of the 3D environment. CD34+ cells cultured in 3D facilitated the highest expansion and maturation of erythroid cells, including generation of erythroblastic islands and enucleated erythrocytes, while MNCs supported multi-lineage hemopoietic differentiation and cytokine secretion relevant for MDS-RS. Importantly, MDS-RS 3D-cultures supported de novo generation of ring sideroblasts and maintenance of the mutated clone. The 3D cultures effectively model a clonal disease characterized by terminal erythroid failure and can be used to assess therapeutic compounds.

Abstract
The presence of lesions on the pig carcass is an indicator of poor animal welfare and has economic impact as it downgrades the carcass value. The assessment of the age of lesions on the carcass may help identify risk factors and ultimately prevent their occurrence. The aim of this study was to assess the age of lesions on pig carcasses through spectrophotometric color evaluation and to relate the results with gene expression and histological and histochemical parameters. A total of 96 barrows were mixed 4 times over 3 d before slaughter and 80 lesions were selected after skin lesion observations to define 4 age categories: < 7 h (T1), 7-25 h (T2), 25-30 h (T3), and 49-54 h (T4). A nonlesioned skin area was used as a control. At slaughter, 3 biopsies per lesion and control skin were taken immediately after bleeding for analyses of gene expression (, , , , , , , , , ), skin histological characteristics (inflammation, erosion or ulceration, and necrosis), and enzyme activity (alkaline phosphatase and adenosine triphosphatase). The number of lesions was counted on each carcass, and the color was assessed visually by a pictorial chart and instrumentally through a spectrophotometer. Delta values (Δ) were calculated as the difference between the value of the lesion and the value of the control for all measures, except for the histological analysis. Results indicated that visual color observation was not sufficiently accurate to discriminate lesions by time of infliction ( > 0.10), while the spectrophotometer ΔL* and Δa* values variation allowed the identification of < 7 h or > 25 h old lesions ( < 0.05). Similarly, the expression of , , , , and genes was higher ( < 0.05) in < 7 h old lesions, while gene expression was higher ( < 0.05) in < 25 h old lesions. As for the histological analysis, the severity of inflammation was correlated with the age of the lesion (lower score in < 7 h old lesions and higher score in > 25 h old lesions; < 0.05). To conclude, the spectrophotometric color assessment of the carcass lesions at slaughter appears to be a reliable method to discriminate between fresh and older lesions on the carcass at the abattoir.

Abstract
Mutations in the RNA splicing gene SF3B1 are found in >80% of patients with myelodysplastic syndrome with ring sideroblasts (MDS-RS). We investigated the origin of SF3B1 mutations within the bone marrow hematopoietic stem and progenitor cell compartments in patients with MDS-RS. Screening for recurrently mutated genes in the mononuclear cell fraction revealed mutations in SF3B1 in 39 of 40 cases (97.5%), combined with TET2 and DNMT3A in 11 (28%) and 6 (15%) patients, respectively. All recurrent mutations identified in mononuclear cells could be tracked back to the phenotypically defined hematopoietic stem cell (HSC) compartment in all investigated patients and were also present in downstream myeloid and erythroid progenitor cells. While in agreement with previous studies, little or no evidence for clonal (SF3B1 mutation) involvement could be found in mature B cells, consistent involvement at the pro-B-cell progenitor stage was established, providing definitive evidence for SF3B1 mutations targeting lymphomyeloid HSCs and compatible with mutated SF3B1 negatively affecting lymphoid development. Assessment of stem cell function in vitro as well as in vivo established that only HSCs and not investigated progenitor populations could propagate the SF3B1 mutated clone. Upon transplantation into immune-deficient mice, SF3B1 mutated MDS-RS HSCs differentiated into characteristic ring sideroblasts, the hallmark of MDS-RS. Our findings provide evidence of a multipotent lymphomyeloid HSC origin of SF3B1 mutations in MDS-RS patients and provide a novel in vivo platform for mechanistically and therapeutically exploring SF3B1 mutated MDS-RS.

Abstract
PURPOSE The aim of this study was to investigate homophobic attitudes in three European countries: Italy, Albania, and Ukraine. One thousand and forty-eight students were recruited in Italian (n = 766), Albanian (n = 180), and Ukrainian (n = 102) university centers. METHODS A socio-demographic questionnaire and Homophobia Scale (HS) were administered by our staff. RESULTS Cross-cultural and significant differences among Italian, Albanian, and Ukrainian students were found on the Homophobia Scale (HS; Italy: mean = 22.26 ± 16.73; Albania: mean = 38.15 ± 17.28; Ukraine: mean = 59.18 ± 16.23). The analysis of socio-demographic characteristics revealed that the male gender emerged as main predictor of homophobic attitude in all the three countries, although also a conservative political orientation and the religious belief predict higher homophobia levels in Italy and Albania, particularly. CONCLUSIONS This study revealed that in these European countries assessed, attitudes toward homosexuality are different. Ukrainians display higher levels of homophobia than Albanians and Italians, confirming the central role of cultural differences in homophobic attitudes. Nevertheless, some socio-demographic aspects such as identification as male have a similar influence on homophobic attitudes in all assessed populations.

Abstract
Refractory anaemia with ring sideroblasts (RARS) is distinguished by hyperplastic inefficient erythropoiesis, aberrant mitochondrial ferritin accumulation and anaemia. Heterozygous mutations in the spliceosome gene SF3B1 are found in a majority of RARS cases. To explore the link between SF3B1 mutations and anaemia, we studied mutated RARS CD34+ marrow cells with regard to transcriptome sequencing, splice patterns and mutational allele burden during erythroid differentiation. Transcriptome profiling during early erythroid differentiation revealed a marked up‐regulation of genes involved in haemoglobin synthesis and in the oxidative phosphorylation process, and down‐regulation of mitochondrial ABC transporters compared to normal bone marrow. Moreover, mis‐splicing of genes involved in transcription regulation, particularly haemoglobin synthesis, was confirmed, indicating a compromised haemoglobinization during RARS erythropoiesis. In order to define the phase during which erythroid maturation of SF3B1 mutated cells is most affected, we assessed allele burden during erythroid differentiation in vitro and in vivo and found that SF3B1 mutated erythroblasts showed stable expansion until late erythroblast stage but that terminal maturation to reticulocytes was significantly reduced. In conclusion, SF3B1 mutated RARS progenitors display impaired splicing with potential downstream consequences for genes of key importance for haemoglobin synthesis and terminal erythroid differentiation.

Abstract
The objective was to assess sows' lameness by measuring weight distribution on limbs using a force plate made up of 4 individual platforms each resting on 4 single-ended beam load cells. The weight was recorded at an average rate of 14 readings per s over a 15 min period. Ten sows (5 lame sows and 5 sound sows) were weighed twice on 2 different days to assess the repeatability of the measure. Sixty-one sows were then selected in 2 different sites and visually scored for lameness, using a 3-point scoring system (0=normal gait; 1=abnormal gait, and/or stiffness; and 2=shortened stride, and/or the sow puts less weight or avoids putting weight on 1 leg). Various measures were recorded from each sow using the force plate (percentage of weight, the ratio between the weights applied by contralateral legs, weight shifting, and amplitude of weight bearing and weight removing), kinematics (speed, stride length, swing time, stance time, foot height, and carpal and tarsal joints angle average and amplitude), and accelerometers (time spent standing during 24 h, frequency of stepping behavior during feeding, and latency to lie down after feed delivery). The within-sow CV for each measure taken from the force plate were lower than 15%, which reflects a good repeatability. Among force plate measures, only the weight shifting frequency and the ratio between the weights applied by contralateral legs differed between lameness scores. Sows that scored 2 had a higher frequency of weight shifting for fore legs (P=0.0003) and hind legs (P=0.0007) than sows scored 0 and 1. The ratio between the weights applied by contralateral legs decreased with the increase of lameness score for the hind limbs (P=0.014). However, these measures also differed between sites (P<0.01). These differences may be due to various reasons, including but not limited to genetics and housing systems. Nevertheless, the results suggest that force plate measures such as the asymmetry in the weight applied between a pair of legs and weight shifting are good indicators of lameness. Multivariate analysis on fore and hind legs showed independency between variables related to animals in movement (measures from kinematics) and variables related to static animals (measures from the force plate and accelerometers). Therefore, both static and dynamic methods need to be used to detect various lame sows.

Abstract
The Chronic Venous Insufficiency (CVI) of inferior limbs is a widespread disease, with an increasing incidence as a consequence of longer life expectance, life-style, obesity, smoking, use of drugs as oestrogens and progestins and working conditions. Medical therapy is still lacking for evidence of efficacy, and compression therapy is useful only in preventing a worsening of this condition. Surgical treatment is the only radical therapy effective for the advanced phases of the disease. In this context spa balneotherapy can be considered as a possible chance to improve some subjective and objective symptoms of CVI of inferior limbs, and to prevent worsening of this condition. The authors performed a review of the relevant scientific literature concerning the treatment of CVI of inferior limbs with mineral water balneotherapy, in order to evaluate its effects on objective and subjective symptoms and its effectiveness to prevent further worsening. We searched the PubMed/Medline, Cochrane Library, Embase, Web of Science databases for articles published between 1990 and 2011 on this topic. To this end, the authors selected few clinical-controlled and case-controlled studies; patients affected from CVI of inferior limbs were treated with balneotherapy at health spas with sulphureous, sulphate, salsojodic or salsobromojodic mineral waters. Baths in mineral waters were often associated with idromassotherapy and vascular pathway. Effects of spa balneotherapy are related to some aspecific properties, like hydrostatic pressure, osmotic pressure and water temperature, partly related with specific chemico-physical properties of the adopted mineral water. The controlled clinical studies on spa therapy showed significant improvement of subjective (such as itch, paresthesias, pain, heaviness) and objective symptoms (namely edema and skin discromias). These studies suggest that spa balneotherapy may give a good chance of secondary prevention and effective therapy of CVI of inferior limbs, but also that it needs of other clinical controlled trials.

Abstract
Refractory anemia with ring sideroblasts (RARS) is characterized by mitochondrial ferritin (FTMT) accumulation and markedly suppressed expression of the iron transporter ABCB7. To test the hypothesis that ABCB7 is a key mediator of ineffective erythropoiesis of RARS, we modulated its expression in hematopoietic cells. ABCB7 up and downregulation did not influence growth and survival of K562 cells. In normal bone marrow, ABCB7 downregulation reduced erythroid differentiation, growth and colony formation, and resulted in a gene expression pattern similar to that observed in intermediate RARS erythroblasts, and in the accumulation of FTMT. Importantly, forced ABCB7 expression restored erythroid colony growth and decreased FTMT expression level in RARS CD34+ marrow cells. Mutations in the SF3B1 gene, a core component of the RNA splicing machinery, were recently identified in a high proportion of patients with RARS and 11 of the 13 RARS patients in this study carried this mutation. Interestingly, ABCB7 exon usage differed between normal bone marrow and RARS, as well as within the RARS cohort. In addition, SF3B1 silencing resulted in downregulation of ABCB7 in K562 cells undergoing erythroid differentiation. Our findings support that ABCB7 is implicated in the phenotype of acquired RARS and suggest a relation between SF3B1 mutations and ABCB7 downregulation.

Abstract
Apolipoprotein L-1 (APOL1) gene variants are associated with end-stage renal disease in African Americans (AAs). Here we investigate the impact of recipient APOL1 gene distributions on kidney allograft outcomes. We conducted a retrospective analysis of 119 AA kidney transplant recipients, and found that 58 (48.7%) carried two APOL1 kidney disease risk variants. Contrary to the association seen in native kidney disease, there is no difference in allograft survival at 5-year posttransplant for recipients with high-risk APOL1 genotypes. Thus, we were able to conclude that APOL1 genotypes do not increase risk of allograft loss after kidney transplantations, and carrying 2 APOL1 risk alleles should not be an impediment to transplantation.

Abstract
More than 20 years of serological approach to diagnosis of celiac disease (CD) has deeply changed the classical clinical presentation of the disease, and some reports indicate that CD and obesity can coexist in both childhood and adolescence. We reviewed clinical records of 149 children with CD followed in our institution between 1991 and 2007, considering weight, height and body mass index (BMI), both at diagnosis and after at least 12 months of gluten-free diet (GFD). In all, 11% of patients had BMI z-score >+1 and 3% were obese (z-score >+2) at presentation. In our population, there was a significant (P=0.008) increase in BMI z-score after GFD and the percentage of overweight (z-score >+1) subjects almost doubled (11 vs 21%, P=0.03). Our data suggest the need for a careful follow-up of nutritional status after diagnosis of CD, especially addressing those who are already overweight at presentation.

Abstract
OBJECTIVES The objective of the study was to ascertain the appropriateness of indications for upper gastrointestinal (UGI) endoscopy in children with dyspepsia. METHODS We used the RAND/University of California at Los Angeles method to investigate the appropriateness of the opinions of a panel of experts. The panel judged 2304 theoretical patient scenarios defined by a combination of demographic and clinical variables. Descriptive and multivariate logistic regression analyses were performed. RESULTS The panel rated UGI endoscopy as appropriate in 27.2% of cases, inappropriate in 14.3%, and dubious in 58.5%. Disagreement emerged for 21% of cases. UGI endoscopy was considered increasingly appropriate in cases with a positive family history of peptic ulcer and/or Helicobacter pylori infection (odds ratio [OR] 8.518, P < 0.0001), when dyspepsia interfered with activities of daily living ("sleep" OR 7.540, P < 0.0001; "normal activities" OR 5.725, P < 0.0001), and when patients were older than 10 years ("<or=10 years" OR 0.310, P < 0.0001) the longer the duration ("0-2 months" OR 0.002, P < 0.0001; "3-5 months" OR 0.059, P < 0.0001; "6-11 months" OR 0.516, P = 0.0005) and the greater the severity ("mild" OR 0.002, P < 0.0001; "moderate" OR 0.013, P < 0.0001) of their dyspeptic symptoms. CONCLUSIONS UGI endoscopy is not appropriate for all children with dyspeptic symptoms, but only for cases with a family history of peptic ulcer and/or Helicobacter pylori infection, older than 10 years of age, with symptoms persisting for more than 6 months and severe enough to affect activities of daily living.

Abstract
Vehicle collisions represent more than 75% of mechanism of blunt abdominal trauma. In spite of the incomparable improvement of car safety devices, recent studies pointed out that the air bags might cause injuries, specially when it is not associated with seatbelt. In fact, some studies pointed out that crash victims using air bags alone have increased injury severity, hospitalisations, thoracoabdominal procedure, and rehabilitation. Some of the most frequently injured organs reported from air bag deployment are the liver (38%), the spleen (23%) and digestive system (17%). Injury of the hollow viscera are far less common. In particular, blunt abdominal trauma resulting in small bowel perforation is an infrequent lesion. These injuries are difficult to diagnose because specific signs are poor and a delay in treatment increases mortality and morbidity of the patients. We describe a case of thoracoabdominal trauma that occurred during a head-on collision after an air bag deployment without seatbelt use.

Abstract
AIMS Colorectal resection (CR) increases plasma VEGF levels which may promote residual tumor growth. This study assessed the effect of perioperative GMCSF on plasma levels of sVEGFR1, Ang-1 and Ang-2 and also the impact of post-GMCSF plasma on in vitro endothelial cell (EC) growth and invasion. Ang-2 increases while sVEGFR1 and Ang-1 impede angiogenesis. METHODS Fifty-nine CR cancer patients were randomized to 7 perioperative doses of GMCSF or saline for 3days prior and 4days after CR. Blood samples were taken pre-drug (PreRx) and on several postoperative days (POD). Protein levels were assessed and PreRx and POD 5 plasma added to EC cultures after which branch point formation (ECBPF) and invasion (ECI) were measured. RESULTS sVEGFR1 levels were significantly higher on POD 1 and POD 5 in both groups but the GMCSF POD 5 level was twice the control value (p=0.002). Ang-2 levels were higher on PODs 1 and 5 in both groups (p<0.05) but the control POD 5 value (vs. GMCSF) was greater (p=0.03). Ang-1 decreases were noted in all (p=not significant, ns). The control group POD 5 ECBPF was 35.8% greater than Pre Rx (p=0.001) while the GMCSF result was 18.0% lower (p=ns); the control POD 5 median percent change from baseline was greater than the GMCSF result(p=0.008). The POD 5 ECI was +12.2% for the control group vs. baseline (p=ns) and -17.2% for the GMCSF group (p=ns): the control median percent change was greater than in the GMCSF group(p=0.045). CONCLUSION CR-related plasma changes are proangiogenic (>Ang-2) and anti-angiogenic (>sVEGFR1); the net effect is promotion of in vitro ECBPF. GMCSF limits the proangiogenic changes (higher POD 5 sVEGFR1 levels and lower Ang-2 elevations, lower POD 5 ECBPF and ECI). The clinical import of these effects is unclear; perioperative GMCSF has anti-angiogenic plasma effects that may limit tumor growth. Further investigation is warranted.

Abstract
UNLABELLED In patients with community-acquired pneumonia (CAP), bacterial-cell-wall-derived fragments may induce the coagulation cascade. To contribute to the knowledge of underlying mechanisms, we have studied the fibrinolytic activity in children with CAP and parapneumonic effusions. PATIENTS AND METHODS Twenty previously healthy children admitted to our Department with CAP were studied; with (n = 11) or without (n = 9) pleural effusion (PPE). We also investigated 10 children with empyema. In all children we analyzed coagulation and fibrinolytic parameters and compared the results to nine controls. RESULTS Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were not significantly modified in the three groups as compared to controls (P = 0.975, P = 0.535, respectively). The fibrinogen levels were significantly increased in respect to the control group (P < 0.0001). The median values of D-dimer showed an increasing trend that was statistically significant: children with pneumonia 244 microg/L, with pneumonia and PPE 751 microg/L and with empyema 2003 microg/L, in respect to values (48 microg/L) of our control group (P < 0.0001). CONCLUSION The results suggest that plasma level of D-dimer can give an additional contribution for the evaluation of the severity of CAP and its complications in children.

Abstract
BACKGROUND Several studies have suggested a link between coeliac disease and other autoimmune diseases. AIM To compare the presence of autoimmune disease in children with coeliac disease and in controls. METHODS When coeliac disease was diagnosed, 267 children were evaluated for clinical autoimmune disease (with signs/symptoms), subclinical autoimmune disease (with autoantibodies and subclinical impairment of the target organ) or potential autoimmune disease (with autoantibodies only) and compared with 220 healthy controls. 170 coeliac disease patients were followed up for a mean 47 +/- 31 months, in complete remission on a gluten-free diet. Ninety-nine controls were followed up for 45 +/- 33 months. RESULTS When coeliac disease was diagnosed, 71 (27%) children had autoimmune disease vs. 1% among the controls (P < 0.001): 31 had clinical autoimmune disease and 40 had subclinical or potential autoimmune disease. During the follow-up, the clinical autoimmune disease cases slightly decreased from 12% to 11%, while the potential autoimmune disease cases increased from 14% to 21%. Of the 99 controls, none had any variation in their autoantibody profile. CONCLUSIONS Gluten-free diet does not modify the natural history of autoimmunity in patients with coeliac disease. However, gluten-free diet seems to produce a favourable effect on the previously present clinical autoimmune disease and to prevent the development of new clinical autoimmune disease, but does not affect the onset of potential autoimmunity, which tends to increase with time.

Abstract
OBJECTIVES To evaluate the esophageal involvement in patients with juvenile localized scleroderma (JLS). METHODS A cohort of patients with JLS underwent esophageal stationary manometry to evaluate esophageal motility and lower esophageal sphincter (LES) function, distal esophagus 24-hour pH-monitoring to detect gastroesophageal reflux (GER) and upper gastrointestinal (GI) endoscopy to evaluate the presence of esophagitis. RESULTS Fourteen patients (10 female, mean age 13.3 yrs, mean disease duration 4.7 yrs), took part in the study. Ten had linear scleroderma, three deep morphea, and one generalized morphea. Esophageal abnormalities were found in 8/14 patients (57%): pathological acid exposure on 24-hour pH-monitoring was found in 7; non-specific esophageal motor abnormalities in 5 and endoscopy-proved esophagitis in 5 symptomatic patients. Interestingly, 5 out of 8 patients with esophageal abnormalities were found to be ANA positive, and 2 were also RF positive. CONCLUSION Esophageal involvement is not unusual in patients with juvenile localized scleroderma, even in the absence of specific symptoms. These preliminary findings, if confirmed in a larger cohort of patients, may support the indication for an extensive GI evaluation especially in presence of positive autoantibodies or specific GI symptoms.

Abstract
Cryptorchidism has an incidence of 0.8 - 2%, being undescendent testis nonpalpable in 20% of the cases. The latters have an increased risk of malignant transformation, infertility and epididymal malformation. Surgical treatment of nonpalpable testis is prone to failure compared to the palpable ones. Many diagnostic methods have been described; the most promising is the use of diagnostic laparoscopy which, compared to the imaging modalities, is more reliable to determine the site of the nonpalpable testis.

Abstract
The peritoneal papillary serous carcinoma (PPSC) is a rare tumor more frequently revealed in female. The onset mean age is 56 years. It implicate peritoneum, ovary's surface and pelvis. The histology of this disease is similar to papillary serous carcinoma ovary (PSCO). The PPSC histogenesis is probably correlated to coelomatic embryonal epithelium. Clinical characteristics are abdominal swelling, constipation, nausea, emesis, inappetence, feel unwell, lose weight. The cytoreductive surgery and the cisplatinum chemotherapy, and other treatments like immunotherapy and radiotherapy, increase the PSCP patient survival. A case of a 51 years old patient with previous surgery for breast cancer is here described. She show some of the yet described clinical findings. At the surgery we found the typically serous peritoneal localizations. We performed a debulking, and the patient died 14 months after the operation due to the disease progression.

Abstract
Tele-mentoring is an interactive experimental method that allows young surgeons' education by distant learning tutoring of an expert surgeon. The problem about assessment of efficacy and quality of computer-assisted instruction is under evaluation today. Tele-mentoring is supported by videoconferencing system and it is not an exclusive methodology but an additional methodology to traditional didactic for clinicians and surgeons. It allows personal virtual trainings by computers and telecommunication systems. Videoconference allows tutoring for telemedicine, teletriage and telesurgery also.

Abstract
The aim of this preliminar report is to evaluate alfa and beta tubulins, components of cellular microtubules, alterated expression in sporadic colorectal cancer patients. The Authors considered 16 patients who underwent surgery for sporadic colorectal carcinoma with radical intent. Alfa and beta tubulins were evaluated in tumoral mucosa by immunohistochemistry. In 56.2% of the examined patients a low expression of alfa and beta tubulins was showed while the alteration of alfa tubulin was showed in 81.2% of the patients. This finding supports the hypothesis of Porter that alterations in microtubule structure might be part of the cellular response to DNA damage.
