AIM:To use more representative sample size to evaluate whether computed tomography(CT)scan evidence of the concomitant presence of pneumatosis and portomesenteric venous gas is a predictor of transmural bowel necrosis.METHODS:Data from 208 patients who were referred for a diagnosis of bowel ischemia were retrospectively reviewed.Only patients who underwent a surgical intervention following a diagnosis of bowel ischemia who also had a post-operative histological confirmation of such a diagnosis were included.Patients were split into two groups according to the presence of histological evidence of transmural bowel ischemia(case group)or partial bowel ischemia(control group).CT images were reviewed for findings of ischemia,including mural thickening,pneumatosis,bowel distension,portomesenteric venous gas and arterial or venous thrombi.RESULTS:A total of 248 subjects who underwent surgery for bowel ischemia were identified.Among the208 subjects enrolled in our study,transmural bowel necrosis was identified in 121 subjects(case group),and partial bowel necrosis was identified in 87 subjects(control group).Based on CT findings,including mural thickening,bowel distension,pneumatosis,pneumatosis plus portomesenteric venous gas and presence of thrombi or emboli,there were no significant differences between the case and control groups.The concomitant presence of pneumatosis and porto-mesenteric venous gas showed an odds ratio of 1.95(95%CI:0.491-7.775,P=0.342)for the presence of transmural necrosis.The presence of pneumatosis plus porto-mesenteric venous gas exhibited good specificity(83%)but low sensitivity(17%)in the identification of transmural bowel infarction.Accordingly,the positive and negative predictive values were 60% and 17%,respectively.CONCLUSION:Although pneumatosis plus porto-mesenteric venous gas is associated with bowel ischemia,we have demonstrated that their co-occurrence cannot be used as diagnostic signs of transmural necrosis. 展开更多

Despite decreasing incidence and mortality rates, gastric cancer (GC) still remains the fourth most common cancer and the second most common cause of cancer-related deaths worldwide. Due to the limited treatment options, at present, prevention is likely to be the only effective means of controlling this disease. The success of a prevention strategy depends upon the understanding of etiological and pathogenic mechanisms underlying gastric carcinogenesis. The etiology of GC is multi-factorial, however, in the recent years, mounting evidence suggests that environmental factors play a key role. The most important environmental factors implicated in the pathogenesis of GC are diet and H pylori infection. Thus, modifications in lifestyle and dietary habit associated with eradication of H pylori infection could hypothetically represent the most promising potential targets for GC prevention. In this review we will address the evidence and the controversies on the role of these agents in noncardia GC by focusing on retrospective and prospective observational studies and interventional trials. 展开更多

We would like to share with the readers the results of our experience in 50 celiac disease(CD)patients,enrolled between September 2012 and April 2013,who were referred to our third-level CD Unit.The fecal calprotectin(FC)concentration of 50 adults with newly diagnosed CD was compared to that of a control group of 50 healthy subjects.FC level was determined by enzyme linked immunosorbent assay with diagnostic cutoff of 75μg/g.In addition,we tried to correlate the FC level with symptoms,histological severity of CD(Marsh grade)and level of tissue transglutaminase antibodies(aTg)in CD patients.Finally,FC level was increased in five CD patients and in four controls(10%vs 8%,P=NS);mean FC concentration of patients and controls were 57.7(SD±29.1)and 45.1(SD±38.4)respectively.Furthermore,no significant correlation was seen between FC levels and symptoms/Marsh grade/aTg.The five CD patients did not show inflammatory lesions(e.g.,ulcers,erosions)at upper endoscopy.The four healthy controls with positive FC were followed-up for further six months;in this observational period they did not show clinical signs of any underlying disease.On these bases,we think that FC is not able to investigate the subclinical inflammatory changes of active CD and FC should be considered a useless tool in the diagnostic work-up of uncomplicated CD but it should be accompanied by aTg when ruling out organic disease in patients with irritable bowel syndrome. 展开更多

Liver biopsy is considered the most accurate means to estimate the necroinflammatory activity and the extent of fibrosis. However, histology evaluation is an invasive procedure associated with risk to the patient, risk of sampling error and diagnostic inconsistencies due to inter- and intra-observer error. On the basis of histological studies performed so far, chronic hepatitis C in children appears morphologically benign in the majority of cases. At the Pediatric Liver Unit of our university, a total of 67 children with chronic hepatitis C underwent liver biopsy. Liver biopsy was repeated 5.5 years after the initial histological evaluation in 21 children. On a total number of 88 liver biopsies, micronodular cirrhosis was detected only in one genotype 1b-infected obese child. Since liver histology investigation of a child with chronic hepatitis C has few chances to highlight severe lesions, we question how liver biopsy helps in the management of children with chronic hepatitis C. 展开更多

Pancreatic vipoma is an extremely rare tumor accounting for less than 2% of endocrine pancreatic neoplasms with a reported incidence of 0.1-0.6 per million. While cross-sectional imaging findings are usually not specific, exact localization of the tumor by means of either computed tomography(CT) or magnetic resonance(MR) is pivotal for surgical planning. However, cross-sectional imaging findings are usually not specific and further characterization of the tumor may only be achieved bysomatostatin-receptor scintigraphy(SRS). We report the case of a 70 years old female with a two years history of watery diarrhoea who was found to have a solid, inhomogeneously enhancing lesion at the level of the pancreatic tail at Gadolinium-enhanced MR(Somatom Trio 3T, Siemens, Germany). The tumor had been prospectively overlooked at a contrast-enhanced multi-detector CT(Aquilion 64, Toshiba, Japan) performed after i.v. bolus injection of only 100 cc of iodinated non ionic contrast media because of a chronic renal failure(3.4 mg/mL) but it was subsequently confirmed by SRS. The patient first underwent a successful symptomatic treatment with somatostatin analogues and was then submitted to a distal pancreasectomy with splenectomy to remove a capsulated whitish tumor which turned out to be a well-differentiated vipoma at histological and immuno-histochemical analysis. 展开更多

Confocal laser endomicroscopy(CLE)is a newly introduced procedure that provide real-time,high-resolution imaging of the gastrointestinal mucosa during endoscopy,allowing the visualization of the pathology of the mucosal epithelium with its cellular and subcellular structures.Recently,the use of CLE was reported in the study of colonic mucosa in patients with inflammatory bowel diseases and in particular in patients affected by ulcerative colitis.CLE has the potential to have an important role in management of inflammatory bowel diseases(IBD)patients as it can be used to assess the grading of colitis and in detection of microscopic colitis in endoscopically silent segments.Moreover,CLE can be used in surveillance programs especially in highrisk patients.Finally,CLE has been effectively used in diagnosing a biliary dysplasia/neoplasia in patients with primary sclerosing cholangitis,a pathological condition frequently associated with IBD,with a coexisting bile duct stricture. 展开更多

Colonic volvulus is a relatively uncommon cause of large bowel obstruction usually involving mobile,intraperitoneal,colonic segments.Congenital or acquired anatomic variation may be associated with an increased risk of colonic volvulus which can occasionally involve retro-peritoneal segments.We report a case of 54-year-old female who presented to our Institution to perform a plain abdominal film series for acute onset of cramping abdominal pain.Both the upright and supine films showed signs of acute colonic obstruction which was thought to be due to an internal hernia of the transverse colon into the lesser sac.The patient was therefore submitted to a multi-detector contrast-enhanced computed tomography(CT).CT findings were initially thought to be consistent with the presumed diagnosis of internal hernia but further evaluation and coronal reformatting clearly depicted the presence of a colonic volvulus possibly resulting from a retro-gastric colon.At surgery,a volvulus of the ascending colon was found and a right hemi-colectomy had to be performed.However,a non rotated midgut with a right-sided duodeno-jejunal flexure and a left sided colon was also found at laparotomy and over-looked in the pre-operative CT.Retrospective evaluation of CT images was therefore performed and a number of CT signs of intestinal malrotation could be identified. 展开更多

Saphenectomy is one of the most validated criteria to treat varicose veins of the lower legs. Although many complications were well described, little is known about compartment syndrome due to muscle ischemia caused by constrictive bandages applied after stripping of varicose veins. We presented a case of successful conservative treatment of compartment syndrome after saphenectomy. Rehabilitation was found effective in improving fatigue, stiffness and tenderness showing the effectiveness of the combined conservative-rehabilitative treatment. However conservative treatment could not be considered the treatment of choice in daily practice. A severity score assessment of compartment syndrome should be useful to assess to which patients is allowed to not perform fasciotomy. 展开更多

Although well recognized for tubo-ovarian abscesses, we report, in our best knowledge, the first case of a vaginal drain of a pelvic abscess due to colonic diverticulitis. A 78-year-old patient presented with abdominal and pelvic pain, fever(39.3 ℃) and an elevated white blood cell count(18500/mL). After abdominopelvic computed tomography the patient was presumed to have a pelvic abscess, which developed as a complication of the sigmoid diverticulitis. Due to the numerous intervening structures that create obstacles to safe percutaneous access, we planned a trans-vaginal drain. A rapid recovery was obtained within 2 d from the procedure and, at present, the follow-up was uneventful after 18 mo. We believe that transvaginal drain of pelvic abscess could be a useful alternative, when percutaneous approach is not feasible. 展开更多

Transmural migrated retained sponges usually impact at the level of the ileo-cecal valve leading to a small bowel obstruction.Once passed through the ileo-cecal valve,a retained sponge can be propelled forward by peristaltic activity and eliminated with feces.We report the case of a 52-year-old female with a past surgical history and recurrent episodes of abdominal pain and constipation.On physical examination,a generalized resistance was observed with tenderness in the right flank.Contrast-enhanced multi-detector computed tomography findings were consistent with a perforated right colonic diverticulitis with several out-pouchings at the level of the ascending colon and evidence of free air in the right parieto-colic gutter along with an air-fluid collection within the mesentery.In addition,a ring-shaped hyperdense intraluminal material was also noted.At surgery,the ascending colon appeared irregularly thickened and folded with a focal wall interruption and a peri-visceral abscess at the level of the hepatic flexure,but no diverticula were found.A right hemi-colectomy was performed and on dissection of the surgical specimen a retained laparotomy sponge was found in the bowel lumen. 展开更多

The use of elastics to close a diastema or correct tooth malpositions can create unintended consequences if not properly controlled. The American Association of Orthodontists recently issued a consumer alert, warning of "a substantial risk for irreparable damage" from a new trend called "do-it-yourself" orthodontics, consisting of patients autonomously using elastics to correct tooth position. The elastics can work their way below the gums and around the roots of the teeth, causing damage to the periodontium and even resulting in tooth loss. The cost of implants to replace these teeth would well exceed the cost of proper orthodontic care. This damage could also occur in a dental office, when a general dentist tries to perform a simplified orthodontic correction of a minor tooth malposition. The present case report describes a case of tooth loss caused by a displaced intraoral elastic, which occurred during a simple preprosthetic orthodontic treatment. 展开更多

The aim of the research was to evaluate, at site scale, the influence of freezing and freeze/thaw cycles on the survival of faecal coliforms and faecal enterococci in soil, in a climate change perspective. Before the winter period and during grazing, viable cells of faecal coliforms and faecal enterococci were detected only in the first 10 cm below ground, while,after the winter period and before the new seasonal grazing, a lower number of viable cells of both faecal indicators was detected only in some of the investigated soil profiles, and within the first 5 cm. Taking into consideration the results of specific investigations, we hypothesise that the non-uniform spatial distribution of grass roots within the studied soil can play an important role in influencing this phenomenon, while several abiotic factors do not play any significant role. Taking into account the local trend in the increase of air temperature, a different distribution of microbial pollution over time is expected in spring waters, in future climate scenarios. The progressive increase in air temperature will cause a progressive decrease in freeze/thaw cycles at higher altitudes, minimising cold shocks on microbial cells, and causing spring water pollution also during winter. 展开更多
