Abstract
Scientific interest related to the role of gut microbiome dysbiosis in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) has now been established and is constantly growing. Therefore, balancing dysbiosis, through probiotics, would be a potential therapy. In addition to scientific interest, on the other hand, it is important to evaluate the interest in these topics among the population. This study aimed to analyze, temporally and geographically, the public's interest in gut microbiome dysbiosis, NAFLD, and the use of gut probiotics. The most widely used free tool for analyzing online behavior is Google Trends. Using Google Trends data, we have analyzed worldwide volume searches for the terms "gut microbiome", "dysbiosis", "NAFLD" and "gut probiotic" for the period from 1, January 2007 to 31 December 2022. Google's relative search volume (RSV) was collected for all terms and analyzed temporally and geographically. The RSV for the term "gut microbiome" has a growth rate of more than 1400% followed, by "gut probiotics" (829%), NAFLD (795%), and "dysbiosis" (267%) from 2007 to 2012. In Australia and New Zealand, we found the highest RSV score for the term "dysbiosis" and "gut probiotics". Moreover, we found the highest RSV score for the term "NAFLD" in the three countries: South Korea, Singapore, and the Philippines. Google Trends analysis showed that people all over the world are interested in and aware of gut microbiome dysbiosis, NAFLD, and the use of gut probiotics. These data change over time and have a geographical distribution that could reflect the epidemiological worldwide condition of NAFLD and the state of the probiotic market.

Abstract
A Morgagni hernia is a congenital diaphragmatic hernia that is rarely diagnosed in adults, and the technique for its repair has not yet been standardized. This review will give an overview of the different laparoscopic methods reported by other authors, highlighting the key points indicating a good repair to help standardize the technique. A systematic review of the available articles on PubMed was conducted according to PRISMA 2020 by two authors independently in May 2022. Only articles written in English were included. A total of 180 case reports of laparoscopic Morgagni's hernia repair procedures were found; direct repair was performed in 59 patients, mesh was used in 119 patients, and mesh was not used in 2 patients. The hernia sac was removed in 71 patients, and the defect was closed before mesh placement in 49 patients. Nonabsorbable, dual or biologic mesh was used. The mean operative time was 92.65 min for direct repair and 84.11 min for mesh repair. One recurrence was reported in the direct repair series. The optimal method of repair has not yet been identified. The laparoscopic approach is associated to fewer complications and facilitates a faster recovery than the open approach. Several manoeuvres have been reported to help surgeons, who are not trained in laparoscopic knotting, perform extracorporeal knotting. Mesh should be placed when tension is too high after a direct repair or when primary closure cannot be achieved.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is one of the most widely practiced surgical procedures in abdominal surgery. Patients undergo LC during general anaesthesia; however, in recent years, several studies have suggested the ability to perform LC in patients who are awake. We report a case of awake LC and a literature review.
CASE SUMMARY A 69-year-old patient with severe pulmonary disease affected by cholelithiasis was scheduled for LC under regional anaesthesia. We first performed peridural anaesthesia at the T8-T9 level and then spinal anaesthesia at the T12-L1 level. The procedure was managed in total comfort for both the patient and the surgeon. The intra-abdominal pressure was 8 mmHg. The patient remained stable throughout the procedure, and the postoperative course was uneventful.
CONCLUSION Evidence has warranted the safe use of spinal and epidural anaesthesia, with minimal side effects easily managed with medications. Regional anaesthesia in selected patients may provide some advantages over general anaesthesia, such as no airway manipulation, maintenance of spontaneous breathing, effective postoperative analgesia, less nausea and vomiting, and early recovery. However, this technique for LC is not widely used in Europe; this is the first case reported in Italy in the literature. Regional anaesthesia is feasible and safe in performing some types of laparoscopic procedures. Further studies should be carried out to introduce this type of anaesthesia in routine clinical practice.

Abstract
There is growing evidence that gut microbiota dysbiosis is linked to the etiopathogenesis of nonalcoholic fatty liver disease (NAFLD), from the initial stage of disease until the progressive stage of nonalcoholic steatohepatitis (NASH) and the final stage of cirrhosis. Conversely, probiotics, prebiotics, and synbiotics have shown promise in restoring dysbiosis and lowering clinical indicators of disease in a number of both preclinical and clinical studies. Additionally, postbiotics and parabiotics have recently garnered some attention. The purpose of this bibliometric analysis is to assess recent publishing trends concerning the role of the gut microbiome in the progression of NAFLD, NASH and cirrhosis and its connection with biotics. The free access version of the Dimensions scientific research database was used to find publications in this field from 2002 to 2022. VOSviewer and Dimensions' integrated tools were used to analyze current research trends. Research into the following topics is expected to emerge in this field: (1) evaluation of risk factors which are correlated with the progression of NAFLD, such as obesity and metabolic syndrome; (2) pathogenic mechanisms, such as liver inflammation through toll-like receptors activation, or alteration of short-chain fatty acids metabolisms, which contribute to NAFLD development and its progression in more severe forms, such as cirrhosis; (3) therapy for cirrhosis through dysbiosis reduction, and research on hepatic encephalopathy a common consequence of cirrhosis; (4) evaluation of diversity, and composition of gut microbiome under NAFLD, and as it varies under NASH and cirrhosis by rRNA gene sequencing, a tool which can also be used for the development of new probiotics and explore into the impact of biotics on the gut microbiome; (5) treatments to reduce dysbiosis with new probiotics, such as Akkermansia, or with fecal microbiome transplantation.

Abstract
PURPOSE In the last 20 years, bariatric surgery has achieved an important role in translational and clinical research because of obesity comorbidities. Initially, a tool to lose weight, bariatric surgery now has been shown to be involved in several metabolic pathways. METHODS We conducted a narrative review discussing the underlying mechanisms that could explain the impact of bariatric surgery and the relationship between obesity and adipose tissue, T2D, gut microbiota, and NAFLD. RESULTS Bariatric surgery has an impact in the relation between obesity and type 2 diabetes, but in addition it induces the white-to-brown adipocyte trans-differentiation, by enhancing thermogenesis. Another issue is the connection of bariatric surgery with the gut microbiota and its role in the complex mechanism underlying weight gain. CONCLUSION Bariatric surgery modifies gut microbiota, and these modifications influence lipid metabolism, leading to improvement of non-alcoholic fatty liver disease.

Abstract
The rate at which obesity is becoming an epidemic in many countries is alarming. Obese individuals have a high risk of developing elevated intraocular pressure and glaucoma. Additionally, glaucoma is a disease of epidemic proportions. It is characterized by neurodegeneration and neuroinflammation with optic neuropathy and the death of retinal ganglion cells (RGC). On the other hand, there is growing interest in microbiome dysbiosis, particularly in the gut, which has been widely acknowledged to play a prominent role in the etiology of metabolic illnesses such as obesity. Recently, studies have begun to highlight the fact that microbiome dysbiosis could play a critical role in the onset and progression of several neurodegenerative diseases, as well as in the development and progression of several ocular disorders. In obese individuals, gut microbiome dysbiosis can induce endotoxemia and systemic inflammation by causing intestinal barrier malfunction. As a result, bacteria and their metabolites could be delivered via the bloodstream or mesenteric lymphatic vessels to ocular regions at the level of the retina and optic nerve, causing tissue degeneration and neuroinflammation. Nowadays, there is preliminary evidence for the existence of brain and intraocular microbiomes. The altered microbiome of the gut could perturb the resident brain-ocular microbiome ecosystem which, in turn, could exacerbate the local inflammation. All these processes, finally, could lead to the death of RGC and neurodegeneration. The purpose of this literature review is to explore the recent evidence on the role of gut microbiome dysbiosis and related inflammation as common mechanisms underlying obesity and glaucoma.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a prevalent, multifactorial, and poorly understood liver disease with an increasing incidence worldwide. NAFLD is typically asymptomatic and coupled with other symptoms of metabolic syndrome. The prevalence of NAFLD is rising in tandem with the prevalence of obesity. In the Western hemisphere, NAFLD is one of the most prevalent causes of liver disease and liver transplantation. Recent research suggests that gut microbiome dysbiosis may play a significant role in the pathogenesis of NAFLD by dysregulating the gut-liver axis. The so-called "gut-liver axis" refers to the communication and feedback loop between the digestive system and the liver. Several pathological mechanisms characterized the alteration of the gut-liver axis, such as the impairment of the gut barrier and the increase of the intestinal permeability which result in endotoxemia and inflammation, and changes in bile acid profiles and metabolite levels produced by the gut microbiome. This review will explore the role of gut-liver axis disruption, mediated by gut microbiome dysbiosis, on NAFLD development.

Abstract
Abstract
Background Play is an integral part of a child's life that could be effectively implemented for hospitalized children as well. It plays an important role in alleviating the psychological burden and enhancing self-efficacy of children undergoing surgery. Children benefit from play or games because they enjoy learning through them. The present study aims to assess the effectiveness of game-based learning on anxiety and postoperative self-efficacy among children undergoing surgery.
Materials and Methods Using nonprobability purposive sampling technique, 80 school-age children undergoing surgery were selected. Children in the interventional group received game-based learning, whereas those in the control group received routine care. A numeric 0 to 10 state anxiety scale and a self-efficacy scale were used for assessing anxiety and postoperative self-efficacy of children. The obtained data was analyzed using descriptive and inferential statistics.
Results Mann–Whitney U test showed significant difference (p < 0.05) between the mean pre- and posttests scores of anxiety in intervention group. Comparison of posttests anxiety scores between the groups also showed a statistical significance (p < 0.05). When compared self-efficacy scores within intervention and control groups, Wilcoxon signed-rank test value was significant (p < 0.05). Whereas between groups comparison the Mann–Whitney U test value was significant (p < 0.05) at 24 and 48 hours after surgery.
Conclusion The study concluded that game-based learning is effective in maintaining adequate postoperative self-efficacy and reducing the anxiety among the children undergoing surgery.

Abstract
In recent decades, haemodynamically stable patients with traumatic liver injuries have been managed conservatively. The primary aim of this study is to retrospectively analyse the outcomes of the authors' approach to blunt hepatic trauma according to the degree of injury. The secondary aim is to analyse the changes in the decision-making process for blunt liver trauma management over the last 10 years. A total of 145 patients with blunt liver trauma managed by one trauma team were included in the study. Causes, sites and grades of injury, clinical conditions, ultrasonography and CT results, associated injuries, laboratory data, types of treatment (surgical or non-operative management/NOM), blood transfusions, complications, and lengths of hospitalization were recorded and analysed. A total of 85.5% of patients had extrahepatic injuries. The most frequently involved liver segments were VII (50.3%), VI (48.3%) and V (40.7%). The most common injury was grade III OIS (40.6%). Fifty-nine patients (40.7%) were treated surgically, with complications in 23.7% of patients, whereas 86 patients (59.3%) underwent NOM, with a complication rate of only 10.5%. The evolution over the last 10 years showed an overall increase in the NOM rate. This clinical experience confirmed that NOM was the most appropriate therapeutic choice for blunt liver trauma even in high-grade injuries and resulted in a 100% effectiveness rate with a 0% rate of conversion to surgical treatment. The relevant increase in the use of NOM did not influence the effectiveness or safety levels over the last 10 years; this was certainly related to the increasing experience of the team and the meticulous selection and monitoring of patients.

Abstract
INTRODUCTION We report an extremely rare case of acute acalculous cholecystitis on a COVID-19 patient. In our knowledge, this is the first report of laparoscopic cholecystectomy performed on a COVID-19 patient. PRESENTATION OF CASE A COVID-19 patient was diagnosed with acute acalculous cholecystitis and a multidisciplinary team decided to perform a percutaneous transhepatic biliary drainage (PTBD) as the first treatment. SARS-CoV-2 RNA was not found in the bile fluid. Because of deterioration of the patient's clinical conditions, laparoscopic cholecystectomy had to be performed and since the gallbladder was gangrenous, the severe inflammation made surgery difficult to perform. DISCUSSION Acalculous cholecystitis was related with mechanical ventilation and prolonged total parenteral nutrition, in this case the gangrenous histopathology pattern and the gallbladder wall ischemia was probably caused by vascular insufficiency secondary to severe acute respiratory distress syndrome of COVID-19 pneumonia. The percutaneous transhepatic gallbladder drainage (PTBD) was performed according to Tokyo Guidelines because of high surgical risk. Laparoscopic cholecystectomy was next performed due to no clinical improvement. The absence of viral RNA in the bile highlights that SARS-CoV-2 is not eliminated with the bile while it probably infects small intestinal enterocytes which is responsible of gastrointestinal symptoms such as anorexia, nausea, vomiting, and diarrhoea. CONCLUSIONS Although the lack of evidence and guidelines about the management of patient with acute cholecystitis during COVID-19 pandemic, laparoscopic cholecystectomy, at most preceded by PTGBD on high surgical risk patients, remains the gold standard for the treatment of acute cholecystitis on COVID-19 patients.

Abstract
Introduction Duodenal rupture following blunt abdominal trauma is rare, and traumatic rupture of duodenal diverticula is exceptional. However, duodenum is the second most frequent location of intestinal diverticula following colon. Duodenal diverticula are common but only in few cases they are symptomatic due to the onset of complications such as inflammation, hemorrhage, or perforation. Perforation, although rare, especially post-trauma, is the most serious life threatening complication. Case presentation We report the case of a patient who, 24 hours after a blunt trauma secondary to a car accident, complained symptoms related to the perforation of a diverticulum of the fourth portion of the duodenum. A computed tomography was performed and extraluminal fluid-air collection was identified. During emergent laparotomy, a fourth portion perforated duodenal diverticulum was diagnosed, and resected. The recovery was uneventful. Discussion Diagnosis of perforated duodenal diverticulum represents a challenge in diagnosis and few guidelines exist about the management of this rare occurrence, especially in a traumatic setting. The present case is the first report of traumatic perforated diverticulum of the fourth duodenal portion. Conclusion Surgery still remain the most common approach in the treatment of this pathology, including diverticulectomy and primary repair. Duodenal diverticula are a frequent, but they are usually asymptomatic until they develop complications, as perforation. Traumatic perforation of duodenum is very infrequent and the traumatic rupture of duodenal diverticula is extremely rare. Perforation, usually involves the second part of the duodenum. The present case is the first report of traumatic perforated diverticulum of the fourth duodenal portion. Surgery remain the most common approach in the treatment of complicated duodenal diverticula.

Abstract
AbstractSublay mesh repair seems to be the most effective method for treating incisional hernias (IHs). The aim of this study was to report our experience with retromuscular repair and self-gripping mesh for the treatment of midline IHs. In addition, we provided a systematic review of the literature regarding the use of this novel combination. All patients undergoing elective IH repair from June 2016 to November 2018 were included. The self-gripping mesh was placed in the sublay position. Demographic data, defect sizes, postoperative complications and follow-up durations were collected. A systematic review of the available literature was conducted in January 2020 using main databases. A total of 37 patients (20/17M/F) were included in this study, and the mean age and body mass index (BMI) were 58 years and 27 kg/m2, respectively. Minor complications occurred in six patients. Long-term follow-up demonstrated recurrence in three patients. Regarding the review, five publications were considered relevant. The highest complication rate was 28.6%, and the recurrence rate varied from 0 to 5.1%. This is the first review of the literature regarding sublay IH repair using a self-gripping mesh. The low rates of postoperative complications and recurrence in our experience and those reported by most of the reviewed articles demonstrate that this is a safe and effective method for repairing IHs.

Abstract
Complex abdominal wall defects (CAWDs) can be difficult to repair and using a conventional synthetic mesh is often unsuitable. A biological mesh might offer a solution for CAWD repair, but the clinical outcomes are unclear. Here, we evaluated the efficacy of a cross-linked, acellular porcine dermal collagen matrix implant (Permacol) for CAWD repair in a cohort of 60 patients. Here, 58.3% patients presented with a grade 3 hernia (according to the Ventral Hernia Working Group grading system) and a contaminated surgical field. Permacol was implanted as a bridge in 46.7%, as an underlay (intraperitoneal position) in 38.3% and as a sublay (retromuscolar position) in 15% of patients. Fascia closure was achieved in 53.3% of patients. The surgical site occurrence rate was 35% and the defect size significantly influenced the probability of post-operative complications. The long-term (2 year) hernia recurrence rate was 36.2%. This study represents the first large multi-centre Italian case series on Permacol implants in patients with a CAWD. Our data suggest that Permacol is a feasible strategy to repair a CAWD, with acceptable early complications and long-term (2 year) recurrence rates.

Abstract
Microarray technology allows simultaneous measurement of the expression levels of thousands of genes within a biological tissue sample. The fundamental power of microarrays lies within the ability to conduct parallel surveys of gene expression using microarray data. The classification of tissue samples based on gene expression data is an important problem in medical diagnosis of diseases such as cancer. In gene expression data, the number of genes is usually very high compared to the number of data samples. Thus the difficulty that lies with data are of high dimensionality and the sample size is small. This research work addresses the problem by classifying resultant dataset using the existing algorithms such as Support Vector Machine (SVM), K-nearest neighbor (KNN), Interval Valued Classification (IVC) and the improvised Interval Value based Particle Swarm Optimization (IVPSO) algorithm. Thus the results show that the IVPSO algorithm outperformed compared with other algorithms under several performance evaluation functions.

Abstract
BACKGROUND Desmoid-type fibromatosis (DTF) is a "locally aggressive, but not metastasizing" proliferation of soft tissues that is difficult to diagnose pre-operatively. Surgical en bloc resection of abdominal DTF can be difficult or an overtreatment. The diagnosis is therefore crucial for the decision making to minimize unnecessary morbidity. CASE REPORT A 33-year old female patient with an incidental intra-operative diagnosis of a 20 cm mesenteric mass involving the duodenum, jejunum, ileum and right colon underwent extended resection for a DTF. A review of the literature, limited only to mesenteric localization of DTF, was performed for the diagnosis, treatment and outcome. RESULTS Twentyfive cases of DTF have been analyzed. Pre-operative diagnosis was suspected in 20% but 95,2% of all the patients underwent resection without pre-operative diagnosis. In two cases, intra-operative, frozen section diagnosis was unsuccessfully attempted. Complications were reported in 12%, recurrence in 4%, and mortality in 0% of the patients. CONCLUSION Pre-operative diagnosis of mesenteric DTF is challenging in most cases, but it can avoid unnecessary extended surgery. Efforts should be made to achieve a correct pre-operative diagnosis based on more reliable imaging and pathological features, to help in decision making.

Abstract
The Achilles' heel of pancreatic surgery is the management of the pancreatic stump. Leakage from pancreatic anastomosis with subsequent fistula, abscess formation, sepsis, or bleeding is one of the most common causes of morbidity and mortality, and it also contributes significantly to prolonged hospitalization and increased hospital expenses. Many surgical methods have been developed aimed at reducing the incidence of post-operative pancreatic fistula. However, the best technique for pancreatico-enteric reconstruction continues to be disputed. Herein, we describe an interim analysis of 35 consecutive pancreatico-duodenectomies, all with the same standardized technique that combines microsurgical technique for duct-to-mucosa pancreatico-jejunostomy with the routine use of fibrin sealant. The rate of leakage of pancreaticojejunostomy was 5,7% (n=2), all of which were grade A fistulas, treated conservatively. The increased precision of magnification instruments and microsurgical technique for duct to mucosa anastomosis, combined with routine sealing of the pancreatic anastomosis are key factors to efficiently manage the pancreatic stump. The good results obtained and especially the minimal rate of fistula suggests that this technical solution is a safe, feasible and reliable approach for pancreatic reconstruction after pancreatico-duodenectomy.

Abstract
INTRODUCTION Many surgical options exist to treat rectal prolapse with different indications, feasibility and results in urgent and complicated cases. These include perineal or abdominal approaches including rectopexy with or without resection. Perineal approaches have reduced surgical invasivity and hospital stay if compared to transabdominal approaches by open surgery or laparoscopy. Up to now there was still a clear dividing line for surgical treatment between the perineal approach, used more for complicated emergency case while the transabdominal open, or laparoscopic approach more common in elective surgery, but more complex to perform. PRESENTATION OF CASE A 37 year old female patient affected by psychiatric disease presented with an unreducible second recurrence of a complicated rectal prolapse. The patient was treated with a third Altemeier procedure but now performed under laparoscopic control. The patient recovered promptly without any complication or recurrence up to the 24 months follow-up. DISCUSSION To the best of our knowledge, this is the first case report describing the combined laparoscopic-perineal approach for the treatment of a complicated recurrence of rectal prolapse. The technical feasibility, the rapidity, the optimal outcome and the rationale behind this option all suggest that this laparoscopic assistance certainly allows an implementation of the effectiveness, safety and results of an established effective perineal approach. CONCLUSION This combined approach has the advantage of maintaining the simplicity and rapidity of conventional perineal surgery, adding the advantages of abdominal control and avoiding the risks, the invasivity, and the longer duration of more complex laparoscopic procedures.

Abstract
UNLABELLED Vaginal evisceration is a rare emergency complication which needs prompt surgical treatment. We report a rare case of a seventy-three year old patient presented with late onset of transvaginal intestinal evisceration, 20 years after hysterectomy. A short review of the literature focused on the last 10 years. The laparoscopic approach represents an additional risk factor for evisceration, but data are poor, and prospective studies are difficult to perform. The treatment of transvaginal evisceration is exclusively surgical, by abdominal, transvaginal or combined abdominal-vaginal approaches along with laparoscopy. The abdominal and combined vaginal-abdominal approaches, allow a complete inspection of the abdominal cavity and to apply a mesh for repairing and preventing recurrences. Transvaginal evisceration despite being rare, can still represent a challenging problem in emergency for general surgeons and gynecologists. Knowledge of the related problems and the surgical approach is mandatory to optimize the outcome. KEY WORDS Evisceration Complication, Mesh repair, Post-hysterectomy.

Abstract
BACKGROUND/AIMS The Barcelona Clinic Liver Cancer (BCLC) classification has been recently validated as the best system for treatment guidance for hepatocellular carcinoma (HCC). The aim of this retrospective study is to evaluate the usefulness of BCLC in the treatment of HCC comparing our treatment decision and the BCLC algorithm indications. METHODOLOGY In 102 patients affected by HCC observed from 1991 to 2002 a retrospective analysis was performed. The choice of treatment was compared with the treatment schedule proposed by BCLC. Whereas the second group of 62 patients observed from 2008 to 2010 was analysed both retrospectively in comparison with the BCLC classification. RESULTS We found a disagreement in between our decision making and the choices suggested by BCLC. We only found a statistical significance for age and performance status test. In surgical patients the median age and the PST class were lower with a statistically significant p value (0.04 and 0.03, respectively). CONCLUSIONS The BCLC system would not have changed our decision either in the past, or in present days, especially in surgical indications. Even if the decision making is affected by BCLC, actually that process still needs the support of the experience of each clinical centre involved.

Abstract
PURPOSE There is no standard anastomosis technique for performing reconstruction after right hemicolectomy, and, in the literature, studies on ileocolonic anastomosis are rare. The aim of this retrospective work was to analyze the type of anastomosis techniques used and the related results in a multicentric enquiry. METHODS A questionnaire was sent to the departments of surgery covering a 1.8 million inhabitant area to collect data concerning the anastomosis techniques used and the results related to complications. RESULTS Data for 999 patients from 14 departments of surgery were collected. 95.8% of the patients were affected by cancer and 4.2% were affected by inflammatory bowel disease (IBD). The positioning of the anastomosing bowel was side-to-side in 60.5% of the patients, end-to-side (E-S) in 38.1% of the patients and end-to-end in 1.3% of the patients. 46.4% of the anastomoses were handsewn and 53.6% were stapled. The complication rate in the cancer group was 5.1% for handsewn techniques and 4.7% for stapled techniques. The rate of anastomotic leakage was higher in the handsewn group than that in the stapled group (P < 0.05). The data for the IBD group were not statistically relevant. CONCLUSIONS This wide multicentric retrospective analysis showed that there remains variability in ileocolonic anastomosis techniques. Stapled anastomoses are associated with a lower incidence of leakage. In stapled anastomoses, the E-S configuration is also related to a lower incidence of leakage.

Abstract
BACKGROUND Until now no data on allergic sensitization to rodents allergens in Western Europe and Italy are available. The aim of this report was to investigate clinical significance and characteristics of IgE-mediated sensitization to mouse/rat (M/Rt) allergens in atopic subjects not occupationally exposed to these animals and living in urban area of Naples. METHODS In 1765 consecutive outpatients, we selected all subjects with an immediate skin reaction to M/WRt dander clinical history including a carefijul evaluation ofthe modality of exposure, the results of skin-prick tests (SPTs) and specific IgE antibodies were recorded. RESULTS Among 1185 SPT-positive patients, 22 were sensitized to M/Rt dander (respectively 1.60% and 0.59%). No patient was mono-sensitized Only three of 22 patients reported indoor conditions suggesting presence of rodents allergens at home. All patients exhibited low degree of SPT positivity and low levels of circulating IgE antibodies to M/WRt. Highfrequency of concomitant allergic sensitization to pet (and other animal) dander has been found. CONCLUSIONS Our results suggest that role of allergic sensitization to rodents is negligible in atopic subjects without occupational exposure living in urban area of Naples. However, highly atopic individuals especially those already sensitized to common pet dander should be tested by SPTs/evaluation of serum specific IgE to rodents in the case they could begin an occupational exposure to M/Rt or keeping these animals as pets.

METHODS: All patients admitted for obstructive jaundice, in the period 2005-2009, were prospectively enrolled in the study, obtaining a total of 102 patients. On admission, all patients underwent complete standard blood test examinations including C-reactive protein (CRP), bilirubin, CA19-9. Patients were considered eligible for the study when they presented obstructive jaundice confirmed by instrumental examinations and increased serum bilirubin levels (total bilirubin > 2.0 mg/dL). The standard cut-off level for CA19-9 was 32 U/mL, whereas for CRP this was 1.5 mg/L. The CA19-9 level was adjusted by dividing it by the value of serum bilirubin or by the CRP value. The patients were divided into 2 groups, MJ and BJ, and after the adjustment a comparison between the 2 groups of patients was performed. Sensitivity, specificity and positive predictive values were calculated before and after the adjustment.
RESULTS: Of the 102 patients, 51 were affected by BJ and 51 by MJ. Pathologic CA19-9 levels were found in 71.7% of the patients. In the group of 51 BJ patients there were 29 (56.9%) males and 22 (43.1%) females with a median age of 66 years (range 24-96 years), whereas in the MJ group there were 24 (47%) males and 27 (53%) females, with a mean age of 70 years (range 30-92 years). Pathologic CA19-9 serum level was found in 82.3% of MJ. CRP levels were pathologic in 66.6% of the patients with BJ and in 49% with MJ. Bilirubin and CA19-9 average levels were significantly higher in MJ compared with BJ (P = 0.000 and P = 0.02), while the CRP level was significantly higher in BJ (P = 0.000). Considering a CA19-9 cut-off level of 32 U/mL, 82.3% in the MJ group and 54.9% in the BJ group were positive for CA19-9 (P = 0.002). A CA19-9 cut-off of 100 U/mL increases the difference between the two groups: 35.3% in BJ and 68.6% in MJ (P = 0.0007). Adjusting the CA19-9 value by dividing it by serum bilirubin level meant that 21.5% in the BJ and 49% in the MJ group remained with a positive CA19-9 value (P = 0.003), while adjusting the CA19-9 value by dividing it by serum CRP value meant that 31.4% in the BJ group and 76.5% in the MJ group still had a positive CA19-9 value (P = 0.000004). Sensitivity, specificity, positive predictive values of CA19-9 > 32 U/mL were 82.3%, 45% and 59.1%; when the cut-off was CA19-9 > 100 U/mL they were, respectively, 68.6%, 64.7% and 66%. When the CA19-9 value was adjusted by dividing it by the bilirubin or CRP values, these became 49%, 78.4%, 69.4% and 76.5%, 68.6%, 70.9%, respectively.
CONCLUSION: The present study proposes CRP as a new and useful correction factor to improve the diagnostic value of the CA19-9 tumor marker in patients with cholestatic jaundice.

Abstract
The Internet and, in particular, social networks are an increasingly important part of daily life for both adolescents and adults who maintain a virtual relationship with others sharing interests and goals. Very often, they disclose more about themselves online than they do in person. However, cyberbullying and cyberostracism can be problematic for adolescents and sensitive individuals, who might be negatively affected by social networks. Some studies have shown an increased risk of depression, whereas others suggest beneficial effects through enhanced communication, social connection, and self-esteem. Bronchial asthma is an increasingly frequent disease in the industrialized world, and psychological implications play a role in increasing or in reducing its severity. One year after the case report of an asthma exacerbation that may have been triggered by Facebook, it seems reasonable to analyze the effects of social networks on bronchial asthma.

Abstract
Gastrointestinal tuberculosis (TB) is quite rare, representing only 3% of all extra-pulmonary cases. Blind gut and ileum are the most common gastrointestinal localizations, while appendix involvement is infrequent. Appendix involvement is usually related to symptoms of acute appendicitis since the caseous necrosis may lead to adhesions and surgical complications such as perforation. For this reason patients with suspected appendicular TB usually undergo surgery even without a secure diagnosis. In these cases, due to the absence of specific symptoms and signs, the diagnosis is delayed after surgery, thus resulting in a high percentage of important, and sometimes lethal, complications. Histopathological examination is often the only way to reach a diagnosis and to establish specific antibiotic therapy, while an early diagnosis could avoid surgical treatment. We report a case of appendicular TB not only for its rarity but also to discuss the difficulty in its diagnosis.

Abstract
BACKGROUND Different approaches are available for the treatment of combined cholecystocholedocholithiasis including totally laparoscopic (TL) treatment, simultaneous laparoendoscopic treatment, and sequential treatments (ST) combining endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (ES) with cholecystectomy. This review aimed to clarify the issue of the simultaneous laparoendoscopic rendezvous (RV). METHODS A careful analysis of papers was performed to determine the results, technical differences, limits, disadvantages, and advantages of RV compared with other options. RESULTS Data were collected from 27 papers concerning 795 patients. The overall effectiveness of RV was 92.3%. The morbidity rate was 5.1%, and the mortality rate was 0.37%. Almost all the authors were satisfied with the procedure. The authors' comparison to ST and TL showed that the advantages outweigh the disadvantages mostly related to logistical problems. CONCLUSIONS There is confusion concerning the definitions and techniques of RV due to differences in combining surgical and endoscopic steps of the procedure. The results are at least comparable with those of the other available approaches. The effectiveness of RV is greater with reciprocal implementation of surgical and endoscopic procedures. The morbidity and the risk of iatrogenic damage seem lower than with ERCP-ES and the risk of residual stones lower than with TL treatment. The RV procedure is safe and can sometimes be the preferable option, but collaboration between surgeon and endoscopist is mandatory.

Abstract
The study was designed to investigate whether exhaled breath condensate, obtained by cooling exhaled air in spontaneous breathing, could be a suitable matrix for toluene quantitative analyses. Nine healthy subjects were exposed for a short period (20 min) to a known concentration of toluene. Exhaled breath condensate samples were collected before and at the end of the exposure, while the environmental concentration of toluene was continuously monitored. Toluene was analysed by head-space gas-chromatography mass spectrometry, and assay repeatability was also estimated in vitro. Baseline and post-exposure measurement of hippuric acid, the urinary toluene metabolite, was performed to assess current toluene exposure. Before the exposure toluene concentrations in the exhaled breath condensate were lower than the detectable limit in all subjects, while after the exposure toluene was detectable with a median value 0.35 microg l-1 (range 0.15-0.55 microg l-1) in all the exhaled breath condensate samples. As compared with the standard calibration in distilled water, the curves obtained by exhaled breath condensate were linear and comparable with the range examined in vivo for toluene. A significant correlation was found between the environmental toluene levels and toluene in the exhaled breath condensate at the end of exposure. Furthermore, a significant relationship between increased exhaled breath condensate toluene levels and urinary hippuric acid after the exposure was found. In conclusion, exhaled breath condensate is a promising matrix for toluene assessment, although its application in humans requires further investigations.

Abstract
The leaves of Nerium indicum Mill. have been utilized traditionally to cure cancer. By Bioassay (BST) guided isolation method, six compounds were isolated from the CHCl3 extract of the leaves. Selectivity of these compounds (in 0.6-12,500 ng/ml) was tested on various human cancer (MCF7, EVSA-T, T47D, H226, IGROV, A498, WIDR, M19, HeLa) and normal (Vero) cells in vitro. Doxorubicin and cysplatin were used as positive controls. The result indicated that NiO2D (5alpha-oleandrin) possessed the best cytotoxic effect on HeLa cells (IC50, 8.38 x10(-6) mM) and NiO2C (16, 17-dehidrodeasetil-5alpha-oleandrin) on A498 cells (IC50, 1.43 x 10(-6) mM). Those two compounds were not cytotoxic to normal cell.

Abstract
BACKGROUND Exhaled nitric oxide (NO) measurement is a simple and non-invasive method for monitoring airway inflammation. Similarly, nasal NO has been proposed as a surrogate marker in inflammatory diseases of the upper airways, e.g. allergic rhinitis. A new portable analyser using an electrochemical sensor has been developed for measurements of exhaled NO, and its reproducibility and comparison with other analysers has been tested recently in healthy subjects and in patients with lower airways disease. The application of this hand-held analyser in nasal NO analysis was tested and compared to the gold standard represented by a chemiluminescence analyser. MATERIALS AND METHODS Thirty subjects including 15 patients with allergic rhinitis (AR) and 15 healthy subjects (HS) were studied. The intraindividual variability, calculated as the difference in nasal NO levels between two measurements from a single nasally exhaled breath manoeuvre, and the comparison between the electrochemical analyser (NIOX MINO, Aerocrine) and a chemiluminescence analyser (NOA, Sievers) were performed. RESULTS In AR patients mean nasal NO was 59.0 +/- 16.3 p.p.b. with the MINO and 58.3 +/- 15.6 p.p.b. with the NOA. In HS nasal NO was 49.1 +/- 10.8 p.p.b. with the MINO and 49.8 +/- 8.2 p.p.b. with the NOA. The Bland-Altman analysis showed bias values of 0.005 +/- 3.6 with the 95% limits of agreement from -6.97 to 6.98 p.p.b. CONCLUSION Measurements of nasal NO levels with a hand-held electrochemical analyser are reproducible and the results are comparable to a stationary chemiluminescence analyser.

Abstract
Upper gastrointestinal tract bleedings may represent the first clinical evidence of peptic ulcer and the related surgical emergency is still characterized by a high mortality rate. The presence of multiple complications, rare but possible in case of duodenal ulcer, such as the fistulization in the common bile duct alone or associated to others, can significantly increase the difficulty in the treatment. The Authors report a particularly complex case of a 77 years old male diabetic patient, with chronic bronchopaty, urgently admitted to our department for hematemesis. Soon after his hemodynamic stabilization, the patient was submitted to surgery which showed a duodenal ulcer with penetration/fistulization in the common bile duct associated to a perforation of the gallbladder with intra-hepatic abscess and erosion of the gastro-duodenal artery. Despite unfavourable outcome the case gave us the starting point for a review of the literature primarily related to the rarer biliary complications of duodenal ulcer. Bleeding ulcers today are usually treated by an interdisciplinary approach comprehensive of endoscopy, interventional radiology and, only rarely, surgery. The choice among the available options depends on the clinical presentation of the patient. Despite diagnostic and therapeutic progresses, peptic ulcer may still rarely have a dramatic presentation and be associated to uncommon and difficult anatomical aspects whose diagnosis and treatment may be not easy at all. The knowledge of all the aspects of peptic ulcer pathophysiology is therefore essential for the treatment of these patients.

Abstract
Traumatic lesions involving the rectum, perineum and anus are infrequent but difficult to treat, requiring experience with trauma and colo-proctological surgery. The aim of the treatment is to repair the lesions and to minimise the early complications which are the main cause of failure and of late complications and disability. The most complicated lesions present problems concerning either the surgical strategy or the surgical timing, both of which are essential for a successful outcome. The Authors analyse their recent clinical experience with 7 patients with complex traumatic lesions involving the rectum, perineum and anus, excluding those of gynaecological/obstetric origin and those not involving the sphincter. They evaluated the clinical history, causes and types of lesions, as well as treatment, complications and outcomes. Five of the lesions were caused by impalement, one by an explosion and one by a motorboat propeller blade. Six of the patients (85.7%) were treated by direct primary repair and one (14.3%) by secondary repair after a previous colostomy. All 7 patients achieved complete recovery of the lesions. Only two cases (28.6%) of early complications and one case (14.3%) of persistent minimal sphincter dysfunction occurred. On the basis of these good results, the clinical experience and the literature, the Authors suggest that these perineo-ano-rectal lesions, though often complex, may often be cured by early surgery, confining colostomy only to particular cases. In addition to experience with trauma and the timing of colo-proctological surgery, a knowledge of all the available surgical options is mandatory to achieve the best results.

Abstract
Gastrointestinal stromal tumour (GIST) of the stomach is extremely rare in the elderly. Surgical resection of the stomach by partial gastrectomy or wedge resection is the standard treatment. Today the resection can also be performed laparoscopically, especially in the case of small tumours as well as for larger GIST though there are unclearly defined oncological limits. The authors report the successful treatment of a large 7.5 cm GIST of the stomach by laparoscopic wedge resection in a 78-year-old patient. The GIST was almost entirely located intraperitoneally between the stomach and the spleen and could be radically resected with a minimal touch technique. The patient recovered promptly and manifested no recurrence at a 2-year follow-up. The authors focus on the main factors supporting the indication for laparoscopic resection of large gastric GIST, especially in the elderly. The surgical risk/benefit ratios of the different approaches, the surgeon's skills in laparoscopically respecting the rules of oncological surgery, and informed consent of the patient in relation to the limited scientific evidence concerning the main risk factors of recurrence are all important considerations.

Abstract
In the human respiratory tract, the main production sites of exhaled nitric oxide (NO) are the nose and paranasal sinuses. In the upper airways, NO has been suggested to be involved at different levels with regulatory, protective, defensive or deleterious effects. Therefore, we review some aspects of the origin, metabolism, and functions of NO in the upper airways, together with the role of NO in some upper airways inflammatory diseases. Furthermore, we discuss the recent improvements in nasal NO measurements, which may be useful to better characterize the involvement of the NO produced by nose and paranasal sinuses in upper airways inflammatory diseases such as allergic rhinitis, nasal polyposis, sinusitis, primary ciliary dyskinesia, and cystic fibrosis.

Abstract
Pulmonary alveolar microlithiasis (PAM) is a rare diffuse lung disease characterised by the accumulation of calcium phosphate microliths within the alveoli. The causative mechanism of PAM has only recently been discovered, and involves a gene mutation of sodium phosphate co-transporter, which is expressed by alveolar epithelial cells. This mutation may have variable consequences on the clinical phenotype. However, pulmonary cell immune phenotyping in familial PAM has not previously been assessed. In the present article, the analysis of bronchoalveolar lavage fluid of two siblings with PAM diagnosis revealed a pattern of lymphocytic alveolitis with accumulation of CD8+ T-cells. The clonal complexity of this lymphocyte's population was assayed by spectratyping, which showed an oligoclonal accumulation of T-cells with a restricted variable beta T-cell receptor (TCR) gene usage. TCR analysis in peripheral blood lymphocytes revealed no abnormal patterns of T-lymphocytes. In the pulmonary alveolar microlithiasis familial cases reported, CD8-mediated maladaptive immune response may have taken place in the bronchoalveolar compartment. The relationship between this immune dysregulation and genetic background in pulmonary alveolar microlithiasis warrants further investigation.

Abstract
The congenital intrapericardial hernia is a rare kind of diaphragmatic hernia. It is due to an embryologic defect of the central tendon of the diaphragm, often accompanied by other congenital malformations. This work presents a unique case report in the literature of the congenital association between intrapericardial diaphragmatic hernia and epigastric hernia in an adult woman. In spite of herniation of the colon and omentum the patient was completely asymptomatic, requesting surgery for an epigastric hernia for aesthetic reasons. The defect of the diaphragm was sutured and the abdominal wall was repaired with a prosthetic mesh.

Abstract
In this study, chicken infectious anemia virus (CIAV) DNA was detected from 12-day-old broilers. Clinical history showed that the clinical features were diarrhea, blue wing disease, depression, and death. Necropsy findings were pale liver, severe atrophy of bursa of Fabricius and thymus, and discoloration of the bone marrow as well as hemorrhages subcutaneously and a few in skeletal muscles. The majority of the necropsied broilers had developed gangrenous dermatitis. Histopathology showed hypoplasia of bone marrow and depletion of lymphocytes in spleen, bursa, and subcapsular thymic cortex. Karyorrhexis of lymphocytes was scattered in the thymic cortex and most pronounced in the bursal follicles. Eosinophilic intranuclear inclusion bodies were mainly located in lymphocytes of thymus, with a few in hemopoietic cells of bone marrow. CIAV DNA was detected by polymerase chain reaction from bursa, thymus, and bone marrow. A virus strain was detected and genetically characterized in 639 base pairs of VP1 gene. Phylogenetic analysis revealed that the Greek isolate was clustered together with isolates from Alabama, China, Slovenia, and Bangladesh.

Abstract
BACKGROUND The effects of severe obesity on right ventricular function in the absence of associated cardiopulmonary disease are not well known. Right myocardial performance index (R-MPI) is an echocardiographic index to non-invasively assess the right ventricular function. The aim of our study was to assess R-MPI in individuals with severe but uncomplicated obesity before and after a significant weight loss induced by bariatric surgery. PATIENTS AND METHODS Fifteen obese females (OB) without cardiovascular and pulmonary diseases were examined. In all subjects, R-MPI was calculated by Doppler echocardiography as the sum of isovolumetric contraction time and isovolumetric relaxation time divided by ejection time. Furthermore, pulmonary function test (PFT) and 6-min walking test (6mWT) were performed. Ten healthy subjects with normal weight (HS) were also evaluated as controls. R-MPI, PFT and 6mWT were also re-evaluated one year later in 12 obese subjects treated with gastric banding after a consistent weight loss (> 20%). RESULTS A prolongation of R-MPI was found in OB before bariatric surgery in comparison to the HS (0.47 +/- 0.04 and 0.29 +/- 0.05, respectively; P < 0.001). R-MPI significantly improved in OB 12 months after surgery (0.32 +/- 0.03) and was no longer different from HS. R-MPI positively correlated to body mass index (BMI). A significant association was found between the reduction of BMI after bariatric surgery and the distance walked during the 6mWT. CONCLUSIONS These results show a right ventricular dysfunction in severe uncomplicated obesity, associated with an impaired functional capacity which recovers after consistent weight loss.

Abstract
BACKGROUND The use of aerosol therapy is commonly suggested in the treatment of paranasal disorders but it is difficult to achieve an effective penetration of drugs into the sinuses. The authors have recently shown that an oscillating airflow produced by phonation (nasal humming) causes a large increase in the gas exchange between the nose and the paranasal sinuses. This is reflected by a high peak in nasally exhaled nitric oxide (NO) levels because NO accumulated in the sinuses is rapidly washed-out via the sinus ostia. OBJECTIVE This study was designed to test whether the increase in sinus gas exchange caused by an oscillating airflow could be used to enhance penetration of a drug into the sinuses. MATERIALS AND METHODS In six healthy subjects a nitric oxide-synthase inhibitor L-NAME was administrated into the nostrils by a jet nebulizer connected to a duck call, which could be modified to generate either a sounding airflow or a non-sounding airflow. The degree of L-NAME penetration into the sinuses was judged from the reduction in nasal NO during humming exhalations. Sinus drug deposition was also studied in a model of the nose and sinus. RESULTS In humans the delivery of L-NAME with the non-sounding airflow had no effect on the NO levels achieved during humming, whereas L-NAME administration with sound caused a significant 22-35% reduction in nasal NO. In the model the aerosol delivery with the sounding airflow caused a fourfold increase in sinus drug deposition as compared with an aerosol without sound. CONCLUSION A sounding airflow increases the delivery of an aerosolized drug into the paranasal sinuses.

Abstract
Latent class models were used to estimate the sensitivity (Se) and the specificity (Sp) of a serum ELISA and a faecal culture (FC) method for the diagnosis of paratuberculosis separately, in sheep and goats. The estimates were obtained by a Bayesian method. Possible dependence of diagnostic errors was investigated by comparing models where independence was assumed to models allowing for conditional dependence given the true disease status. ROC analysis for the serum ELISA was also performed and optimized cut-off values based on the misclassification cost term were determined. No evidence of conditional dependence was found. Assuming independence, posterior medians and 95% credible intervals for the Se(ELISA), Sp(ELISA), Se(FC) and Sp(FC), were 63% (42, 93%), 95% (90, 98%), 8% (2, 17%) and 98% (95, 100%) in goats and 37% (10, 80%), 97% (93, 99%), 16% (2, 48%) and 97% (95, 99%) in sheep. AUC was calculated 0.702 for sheep and 0.847 for goats. For the serum ELISA, there is need of species- and purpose-specific cut-off selection. For instance, with 20% prevalence situation and assuming equal and five-fold cost of a false negative to a false positive test result, the optimal cut-off is 0.3 and 0.05 in sheep, respectively, while it is 0.6 and 0.1 in goats, respectively. Serum ELISA performed better in goats than in sheep. Lowering the cut-off, in relation to the one recommended by the manufacturer, improved Se(ELISA) without seriously compromising Sp(ELISA), in either species.

Abstract
Thirty-nine Greek dairy herds, totalling 6333 cattle, enrolled in a voluntary bovine viral diarrhoea virus (BVDV) eradication programme based on the identification and removal of persistently infected (PI) animals. The aim of this study was to estimate the prevalences of BVD antigen-positive and PI animals, and investigate the significance of the associations between the prevalence estimates and herd size. Initially, all animals were bled and examined for BVDV, using an antigen ELISA. A second sample was collected from the positive animals, after a period of at least three weeks. Animals retested positive were classified as PI. Antigen positive and PI animals were detected in all herds. The respective mean prevalences, adjusted for the test's accuracy and the herd-clustering effect, were 14% (95%CI: 11-18%) and 1.3% (0.8-1.8%), respectively. Herd size was not associated with the prevalence of antigen-positive or PI animals.

Abstract
BACKGROUND When venous system of superior vena cava is not useful or when chest wall is not utilizable to place a reservoir, saphenous vein can be utilized for totally implantable venous access device (TIVAD) placement. Aim of this work is to establish the best location of the reservoir for the function and the comfort of the patient. PATIENTS AND METHODS All the patients submitted to TIVAD placement from January 1995 to October 2004 at the Department of Surgical Science, Organs Transplantations and Advanced Technologies of University of Catania have been considered to the present study. Age, sex, kind of disease, surgical procedure, early and late complications, function of the system and comfort to the patients in relation to the different site of reservoir placement have been studied. RESULTS 447 TIVAD have been implanted in 258 males and 189 females aged from 31 to 79 years in the period considered for the study. Solid tumors represent the majority of the indications and all the TIVAD have been implanted by surgical cutdown to avoid all the early complications related to the percutaneous approach. Two patients received their TIVAD using saphenous vein by surgical cut-down, and no early complications have been recorded. The reservoirs have been placed respectively: in the chest wall in the first patient; and in the anterior wall of the abdomen, close to the anterosuperior iliac crest, firstly and later in the anterolateral face of the thigh in the second one. The first patient had non complications instead the second one referred discomfort with both reservoir locations. CONCLUSIONS For the comfort of the patient related to the reservoir position in case of saphenous vein utilization chest wall should represent the best studies are required to validate the appropriate reservoir location.
