Abstract
We report the case of a young girl (17-year-old) wounded by an accidental gunshot. The bullet entered through the skin midline over the navel area, passed through the stomach perforating the vena cava and, by breaking the right pedicle of L4, moved inside the vertebral canal (bridging the cauda equina) stopping just in front of the body of S2. Because of the sudden onset of acute abdomen due to a massive retroperitoneal hematoma, the patient underwent emergency explorative laparotomy with the evacuation of the hematoma and the suture of the perforated cava vein, the peritoneum, and the stomach. No neurological deficits were observed after the gunshot. Two weeks later, the patient underwent spinal surgery to remove the bullet from the spinal canal, which was performed successfully without any instrumentation and with no onset of new neurological signs and symptoms or surgery-related complications. Patient was discharged on day 9 after surgery in good general conditions.

Video-assisted anterior retroperitoneal approach to the lumbar spine. A minimally invasive technique improved by the use of an endoscopic camera to treat lumbar spinal diseases. Consideration over 269 patients. J BIOL REG HOMEOS AG 2020; 34:7-14. Congress of the Italian Orthopaedic Research Society.

Abstract
We describe the technique we routinely use to perform the retroperitoneal anterior approach using a rigid endoscope coupled to a HDD screen to assist mini-open retroperitoneal anterior approach. Our experience was compared to those reported in the literature for the standard mini-open retroperitoneal approach. We retrospectively analyzed a total of 269 consecutive patients, 109 males and 160 females, underwent anterior lumbar approach in our department, using video-assisted anterior retroperitoneal approach to the lumbar spine. 202 patients had a single L5-S1 or L4-5 ALIF (75.09%), 14 patients received a double level ALIF (5.3%), while 53 patients underwent a double anterior and posterior approach (19.8%). The average preoperative VAS and Oswestry Disability Index (ODI) scores were 9.1±6.3 and 79.3±11.9. At least 16 months follow-up (from 16 months to 5 years), the average VAS and ODI values had improved to 1.6±1.5 and 13.1±13.2, respectively (p <0.05). The mean length of stay was 4.3±3.5 days. There were 6 major complications (2.2%) related to the approach: major vascular injuries (iliac vein injury) occurred in a total of 3 patients (1.1% of cases), whereas retrograde ejaculation occurred in 3 patients (2,75% of male cases in the series). No wound or deep infections occurred. In our opinion, this technique, compared with other mini-open approach, potentially reduces perioperative morbidity, length of surgery, surgical approach-related complications, and hospitalization.

Abstract
Anterior Lumbar Interbody Fusion (ALIF) has gained popularity in the last few years, thanks to its numerous advantages. Recently the use of lordotic cages has been described, allowing theoretically a better lordosis restoration of the lumbar disc space. We described the results obtained with the use of lordotic cages in 27 patients who underwent ALIF procedure for L5-S1 disc degenerative disease, in terms of segmental lordosis and global lumbar lordosis changes.

Abstract
BACKGROUND Synovial cysts are currently classified as degenerative lesions affecting the joint capsule or adjacent structures. MATERIALS AND METHODS In our study we describe the results obtained in an immunohistochemical study comprising 18 patients with synovial cysts, performed to evaluate the pathophysiological role of some inflammatory cytokines such as: interleukin (IL)-1β, IL-6 and tumour necrosis factor-alpha (TNF-α). RESULTS Results showed an over-expression of TNF-α, IL-1β and IL-6 which appears to be involved in the onset and progression of the disease. At the present time it is not possible to affirm that these molecules play a direct role also due to the absence of further and more specific investigations. The authors therefore hypothesize that inhibition of inflammation may have a significant role in the pathogenesis and regression of synovial cysts. CONCLUSIONS Hence, these inflammatory cytokines may be considered potential therapeutic targets. The development of synthetic inhibitors of these inflammatory factors could lead to a reduction in the intensity of inflammation, thus inhibiting the onset and development of the disease.

Guidance for diagnosis and treatment of acute angioedema in the emergency department: consensus statement by a panel of Italian experts. Intern Emerg Med 2014; 9:85-92.

Abstract
Angioedema attacks, characterized by the transient swelling of the skin and mucosae, are a frequent cause of visits to the emergency department. Swellings of the oral cavity, tongue, or larynx can result in life-threatening airway obstruction, while abdominal attacks can cause severe pain and often lead to unnecessary surgery. The underlying pathophysiologic process resulting in increased vascular permeability and plasma extravasation is mediated by vasoactive molecules, most commonly histamine and bradykinin. Based on the mediator involved, distinct angioedema forms can be recognized, calling for distinct therapeutic approaches. Prompt recognition is challenging for the emergency physician. The low awareness among physicians of the existence of rare forms of angioedema with different aetiologies and pathogenesis, considerably adds to the problem. Also poorly appreciated by emergency personnel may be the recently introduced bradykinin-targeted treatments. The main objective of this consensus statement is to provide guidance for the management of acute angioedema in the emergency department, from presentation to discharge or hospital admission, with a focus on identifying patients in whom new treatments may prevent invasive intervention.

Preoperative calculation of the necessary correction in sagittal imbalance surgery: validation of three predictive methods. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2013; 22 Suppl 6:S847-52. [PMID: 24061973 DOI: 10.1007/s00586-013-3025-9] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/14/2013] [Revised: 09/08/2013] [Accepted: 09/08/2013] [Indexed: 10/26/2022]
Abstract
INTRODUCTION Surgery for correction of sagittal imbalance has frequent adverse events and complications. The most frequent cause of failure is inadequate correction of imbalance. The aim of this study is to verify the accuracy of three published methods (exact method by Ondra, FBI method by Le Huec and spinofemoral angle method by Lamartina) to preoperatively calculate the needed correction. DESIGN This is a retrospective cohort study. METHODS Fifteen patients treated for correction of sagittal imbalance, with preoperative and postoperative lateral standing whole spine radiographs, were identified. Preoperative calculation of the amount of needed correction has been done using these methods. In postoperative X-rays, the amount of correction obtained with and the degree of correction of sagittal imbalance have been measured. RESULTS AND DISCUSSION The FBI and SFA methods obtain equivalent calculations of the amount of needed correction. The estimated correction angle with both methods is higher than that calculated with the exact trigonometric method. The difference between the latter and the former methods is equivalent to the observed excess of pelvic tilt.

High-dose probiotics for the treatment of active pouchitis. Dis Colon Rectum 2007; 50:2075-82; discussion 2082-4. [PMID: 17934776 DOI: 10.1007/s10350-007-9068-4] [Citation(s) in RCA: 123] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2006] [Revised: 12/11/2006] [Accepted: 12/11/2006] [Indexed: 12/13/2022]
Abstract
PURPOSE Pouchitis is the major long-term complication after ileal-pouch anal anastomosis for ulcerative colitis. Broad-spectrum antibiotics are the mainstay of treatment in this condition. Recently, we have shown the efficacy of a highly concentrated probiotic preparation (VSL#3, 900 billions/sachet lyophilized viable bacteria) in preventing relapses of chronic pouchitis and in preventing pouchitis onset. This study was designed to evaluate the efficacy of high-dose VSL#3 in the treatment of mildly active pouchitis. METHODS Twenty-three consecutive patients with mild pouchitis, defined as a score of between 7 and 12 in the Pouchitis Disease Activity Index, which includes clinical, endoscopic, and histological criteria, were treated with VSL#3, 2 sachets b.i.d. (3,600 billion bacteria/day) for four weeks. Symptomatic, endoscopic, and histologic evaluations were undertaken before and after treatment according to Pouchitis Disease Activity Index. Remission was defined as a combination of a Pouchitis Disease Activity Index clinical score of <or=2, endoscopic score of <or=1, and total Pouchitis Disease Activity Index score of <or=4. Patients in remission after treatment were treated with VSL#3, 1 sachet b.i.d. (1,800 billion bacteria), as maintenance treatment for six months. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire. RESULTS Sixteen of 23 patients (69 percent) were in remission after treatment. The median total Pouchitis Disease Activity Index scores before and after therapy were 10 (range, 9-12) and 4 (range, 2-11), respectively (P < 0.01). The median Inflammatory Bowel Disease Questionnaire score also significantly improved from 110 (range, 90-140) to 200 (range, 95-220; P < 0.001). All 16 patients who went into remission maintained remission during maintenance treatment. Only one patient experienced a transient bloating at the beginning of treatment. CONCLUSIONS High doses of the probiotic VSL#3 are effective in the treatment of mild pouchitis. Further controlled studies are warranted.

Cutaneous manifestations in inflammatory bowel diseases: eight cases of psoriasis induced by anti-tumor-necrosis-factor antibody therapy. Dermatology 2007; 215:295-300.

Abstract
BACKGROUND Ulcerous rectocolitis and Crohn's disease are the best known forms of inflammatory bowel disease (IBD). Skin manifestations are not uncommon in IBD and may be divided into specific cutaneous signs, aspecific cutaneous signs, and cutaneous signs caused by drugs used for IBD therapy. The specific signs (fistulas, rhagades and ulcers) are the result of the diffusion of the intestinal inflammatory process into the skin. Aspecific cutaneous signs (stomatic aphthosis, erythema nodosum, pyoderma gangrenosum, Sweet's syndrome, vasculitis, bullous diseases) are quite frequently found in those suffering from IBD, but also in apparently healthy subjects, and may sometimes be the first sign of the intestinal disease. Cutaneous manifestations due to drugs vary in clinical aspect and are the direct consequence of the therapies adopted, which in IBD patients can be quite numerous: steroids, immunosuppressants, 5-aminosalicylic acid, biological agents, antibiotics. OBJECTIVE AND METHODS Due to the frequent finding of cutaneous manifestations in patients affected by IBD, a collaboration was set up between the Dermatological Clinic of the University of Bologna and the Center for the Study of IBD of the same university hospital. The aim was to diagnose the cutaneous signs appearing during IBD and to establish their etiopathogenesis in order to assess whether they were the result of epiphenomena of the IBD or side effects of the therapies adopted. RESULTS The cutaneous manifestations we observed can be divided into three distinct groups: signs that were specific to the basic disease, aspecific signs and finally signs attributable to the drugs used for therapy. Particular attention was given to the aspecific signs and those consequential to therapy. The aspecific cutaneous signs seen in our clinic generally reflect those reported in the literature. The cutaneous manifestations due to drugs were further divided into three groups: rosacea, acneiform dermatitis and psoriasis-like dermatitis. The most notable aspect of our series is the high number of patients presenting psoriasiform-type dermatitides with a generally widespread diffusion. CONCLUSION We would like to draw attention to the fact that all patients with psoriasis had been undergoing treatment with drugs inhibiting tumor necrosis factor alpha (TNF-alpha) as part of IBD therapy. In all cases, the cutaneous reaction started after the third or fourth infusion of the biological drug. Anti-TNF-alpha agents have also been successfully used to treat psoriasis in the last few years. The reason for this apparently paradoxical effect of the therapy is still unclear.

Abstract
BACKGROUND Pouchitis is a common long-term complication after ileal pouch anal anastomosis for ulcerative colitis. Chronic refractory pouchitis is a treatment-resistant condition that affects 5-15% of patients. AIM To test the hypothesis of a small bowel involvement using wireless capsule endoscopy. MATERIAL AND METHODS This is a single-blind, prospective, cohort study. Twenty-four patients: 16 were patients with chronic refractory pouchitis and eight, with a macroscopically and histologically normal ileal pouch, were considered as control subjects. Diagnosis of pouchitis was confirmed using the pouchitis disease activity index. All subjects were submitted to wireless capsule endoscopy procedure. Within 2 weeks before wireless capsule endoscopy, patients underwent a pouch endoscopy and a small bowel follow-through. Re-examination of the colonic surgical and histological specimens was also performed. RESULTS One patient with chronic pouchitis was excluded because of incomplete bowel cleaning. At small bowel follow-through of 16 patients, two subjects (13%) showed only a focal ectasia of the middle ileum and a substenosis of the pouch. At wireless capsule endoscopy all the 15 evaluable patients with chronic pouchitis (100%) showed diffuse lesions from duodenum to ileum consisting of aphthae, erosions, erythema, atrophy, cobblestone, deep/fissural ulcers. CONCLUSIONS This enteropathy needs further research, and wireless capsule endoscopy could be useful to show involvement of small bowel in patients with chronic pouchitis.

Abstract
BACKGROUND Pouchitis is the major long-term complication after ileal-pouch nal anastomosis for ulcerative colitis. Ten to 15% of patients develop a chronic pouchitis, either treatment responsive or treatment refractory. AIM To evaluate the efficacy of oral budesonide in inducing remission and improving quality of life in patients with chronic refractory pouchitis. METHODS Twenty consecutive patients with active pouchitis, not responding after 1 month of antibiotic treatment were treated with budesonide controlled ileal release 9 mg/day for 8 weeks. Symptomatic, endoscopic and histological evaluations were undertaken before and after treatment according to Pouchitis Disease Activity Index. Remission was defined as a combination of Pouchitis Disease Activity Index clinical score of < or = 2, endoscopic score of < or = 1 and total Pouchitis Disease Activity Index score of < or = 4. The quality of life was assessed with the Inflammatory Bowel Disease Questionnaire. RESULTS Fifteen of 20 patients (75%) achieved remission. The median total Pouchitis Disease Activity Index scores before and after therapy were, respectively, 14 (range 9-16) and 3 (range 2-10) (P < 0.001). The median Inflammatory Bowel Disease Questionnaire score also significantly improved from 105 (range 77-175) to 180 (range 85-220) (P < 0.001). CONCLUSION Eight-week treatment with oral budesonide appears effective in inducing remission in patients with active pouchitis refractory to antibiotic treatment in this open-label study.

A health assessment of high status Christian burials recovered from the Roman-Byzantine archeological site of Elaiussa Sebaste, Turkey. HOMO-JOURNAL OF COMPARATIVE HUMAN BIOLOGY 2007; 58:173-90.

Abstract
The purpose of this study is to assess the state of health of 116 individuals whose remains were excavated from Byzantine period burials underneath the floor of an important Christian basilica from the site of Elaiussa Sebaste, Turkey. Elaiussa Sebaste was a Mediterranean coastal community, which began as a Roman town and continued as an early Christian Byzantine community until the end of the 7th century AD. The burials date from the middle of the 6th through the middle of the 7th centuries AD. We attempt to determine how high social status has influenced the type and frequency of skeletal lesions exhibited in this sample. All strata of this population show a number of chronic and acute health problems as indicated by skeletal lesions. Yet, only the frequency of degenerative joint disease (DJD) differs by sex, with males exhibiting a higher rate of DJD than females, p=0.09. There is no difference in the frequency of trauma among adult males and females. Non-specific skeletal lesions (cribra orbitalia, porotic hyperostosis, and periostitis) often associated with dietary and general stressors, but also with specific systemic diseases, are common in both sexes. The sub-adults primarily exhibit periostitis of the long bones and do not show skeletal lesions specific to malaria. It seems that high social ranking did not prevent serious ailments from affecting the health of individuals living in the Elaiussa Sebaste community.

Abstract
About two-thirds of patients with ulcerative colitis have an inflammatory involvement distal to the splenic flexure and therefore may be effectively treated with topical treatment. This allows the delivery of the active drug directly to the site of inflammation, limiting the systemic absorption and the potential side effects. Topical aminosalicylate therapy is the most effective approach, provided that the formulation reaches the upper extent of the disease. Suppositories should be considered the treatment of choice for proctitis and distal sigmoiditis. A 1 g Pentasa-suppository once daily induces a quicker clinical and endoscopic remission and was better tolerated than a 500-mg suppository twice daily. Enemas, foams and gel, thanks to their proximal spread, should be the treatment of choice for proctosigmoiditis and left-sided colitis. Oral aminosalicylates are less effective than topical therapies for patients with active disease; however, a combination of oral and topical aminosalicylates can be successfully tried in refractory patients. Topical aminosalicylates also play an important role in the maintenance of remission, and the combination of oral plus rectal 5-aminosalicylate is superior to the single agent. Patients who prefer not to continue on long-term rectal therapy can be treated with oral aminosalicylates.

Abstract
Many experimental and clinical observations suggest a potential role for intestinal microflora in the pathogenesis of inflammatory bowel disease (IBD). Manipulation of the luminal content using antibiotics may therefore represent a potentially effective therapeutic option. However, the available studies do not support the use of antimicrobials in ulcerative colitis and larger studies are required. These drugs are however effective in treating septic complications of Crohn's disease (CD). The use of antibacterial agents as primary therapy for CD is more controversial, although this approach is frequently and successfully adopted in clinical practice. Despite the fact that properly controlled trials have been not carried out, antimicrobials are the mainstay of the treatment of pouchitis. Rifaximin is a poorly absorbed, broad-spectrum antibiotic that, thanks to its efficacy and long-term safety, could represent the preferred tool of manipulating enteric flora in patients with IBD. Preliminary data suggest that rifaximin may be beneficial in the treatment of active ulcerative colitis (and pouchitis), mild to moderate CD as well as prevention of post-operative recurrence of CD.

Abstract
Many experimental and clinical observations suggest that intestinal microflora plays a potential role in the pathogenesis of inflammatory bowel disease (IBD). Manipulation of the luminal content using antibiotics or probiotics represents a potentially effective therapeutic option. The available studies do not support the use of antibiotics in ulcerative colitis (UC). Antibiotics are effective in treating septic complications of Crohn’s disease (CD) but their use as a primary therapy is more controversial, although this approach is frequently and successfully adopted in clinical practice.
There is evidence that probiotic therapy may be effective in the prevention and treatment of mild to moderate UC. In contrast, a lack of successful study data at present precludes the widespread use of probiotics in the treatment of CD.
Both antibiotics and probiotics appear to play a beneficial role in the treatment and prevention of pouchitis and further trials are warranted to fully quantify their clinical efficacy.

Abstract
AIM To investigate the single nucleotide polymorphisms (SNPs) in genes involved in bacterial recognition and the susceptibility to pouchitis or pouchitis severity. METHODS Analyses of CD14 -260C>T, CARD15/NOD2 3020insC, Toll-like receptor (TLR)4 +896A>G, TLR9 -1237T>C, TLR9+2848G>A, and IRAKM + 22148G>A SNPs were performed in 157 ileal-pouch anal anastomosis (IPAA) patients (79 patients who did not develop pouchitis, 43 infrequent pouchitis patients, 35 chronic relapsing pouchitis patients) and 224 Italian Caucasian healthy controls. RESULTS No significant differences were found in SNP frequencies between controls and IPAA patients. However, a significant difference in carriership frequency of the TLR9-1237C allele was found between the infrequent pouchitis and chronic relapsing pouchitis groups [P = 0.028, oddos ratio (OR) = 3.2, 95%CI = 1.2-8.6]. This allele uniquely represented a 4-locus TLR9 haplotype comprising both studied TLR9 SNPs in Caucasians. Carrier trait analysis revealed an enhanced combined carriership of the alleles TLR9 -1237C and CD14 -260T in the chronic relapsing pouchitis and infrequent pouchitis group (P = 0.018, OR = 4.1, 95%CI = 1.4 -12.3). CONCLUSION There is no evidence that the SNPs predispose to the need for IPAA surgery. The significant increase of the combined carriership of the CD14 -260T and TLR9 -1237C alleles in the chronic relapsing pouchitis group suggests that these markers identify a subgroup of IPAA patients with a risk of developing chronic or refractory pouchitis.

Abstract
BACKGROUND Obstructive sleep apnoea has been demonstrated to induce gastrooesophageal reflux through highly negative intrathoracic pressure during the attacks. However, we believe that gastrooesophageal reflux on its part may favour or aggravate the apnoea attacks. AIMS We investigated whether the treatment of gastrooesophageal reflux with omeprazole is able to decrease apnoea attacks. PATIENTS AND METHODS Twenty patients (mean age 55.4 years, range 49-73 years; 17 males) with confirmed obstructive sleep apnoea at overnight polysomnography and pathological gastrooesophageal reflux at ambulatory 24-h oesophageal pHmetry were asked to note in a diary the occurrence of apnoea attacks for a basal period of 4 weeks. Subsequently, the patients were randomly and in a double-blind manner treated with omeprazole 20mg (10 patients, group A) or placebo (10 patients, group B) by giving 1 cp 30 min before breakfast and 1 cp 30 min before dinner for another 6 weeks with a diary documentation. The results were averaged weekly and over the entire treatment duration and a statistical comparison was made between the groups and within each group before and after treatment. RESULTS The mean weekly frequency of apnoea attacks of group A during the entire period of treatment with omeprazole was significantly decreased with respect to the basal period and was significantly lower than that of group B. The weekly frequency of apnoea attacks in group A started to be significantly lower from the third week than the corresponding values of both group B and the basal period, reaching a decrease of about 73% in the sixth week. CONCLUSION The occurrence of apnoea attacks progressively decreased during the treatment of gastrooesophageal reflux with omeprazole. This fact suggests that gastrooesophageal reflux may play a role in triggering and/or worsening obstructive sleep apnoea.

Abstract
BACKGROUND Almost 20% of patients with active Crohn's disease are refractory to conventional therapy. Infliximab is a treatment of proven efficacy in this group of patients and it is not clear which variables predict a good response. AIMS.: To evaluate the role of infliximab looking at the predictors of response in a large series of patients with Crohn's disease. PATIENTS AND METHODS Five hundred and seventy-three patients with luminal refractory Crohn's disease (Crohn's Disease Activity Index (CDAI)>220-400) (312 patients) or with fistulising disease (190 patients) or both of them (71 patients) were treated with a dose of 5 mg/kg in 12 Italian referral centres. The primary endpoints of the study were clinical response and clinical remission for luminal refractory and fistulising disease. We evaluated at univariable and multivariable analysis the following variables: number of infusions, sex, age at diagnosis, smoking habit, site of disease, previous surgery, extraintestinal manifestations and concomitant therapies, and type of fistulas. RESULTS Patients with luminal refractory disease: 322 patients (84.1%) had a clinical response and 228 (59.5%) reached clinical remission. Patients with fistulising disease: 187 patients (72%) had a reduction of 50% of the number of fistulas and in 107 (41%) a total closure of fistulas was observed. For luminal disease, single infusion (OR 0.49, 95% CI 0.28-0.86) and previous surgery (OR 0.53, 95% CI 0.30-0.93) predicted a worse response for fistulising disease. Other fistulas responded worse than perianal fistulas (OR 0.57, 95% CI 0.303-1.097). CONCLUSION In Crohn's disease infliximab is effective in luminal refractory and in fistulising disease. A single infusion and previous surgery predicted a worse response in luminal disease whereas perianal fistulas predicted a better response than other type of fistulas.

Abstract
An increasing number of both clinical and laboratory-derived observations support the importance of luminal components in driving the inflammatory response in ulcerative colitis and Crohn's disease. Although its role is unclear, antibiotic therapy is commonly used in clinical practice for the treatment of moderately to severely active ulcerative colitis. Metronidazole and/or ciprofloxacin are currently employed in active Crohn's disease, particularly in patients with colonic involvement and with perianal disease. Rifaximin, a rifamycin-derived antibiotic, is characterized by a wide range of antibacterial activity and a very low systemic absorption. Some preliminary data show its efficacy in severe active ulcerative colitis, pouchitis and prevention of postoperative recurrence in Crohn's disease.

Abstract
BACKGROUND Probiotic therapy has been shown to prevent the onset of pouchitis and to improve the quality of life in ulcerative colitis patients who required ileal pouch anal anastomosis. Pouchitis has been associated with elevated levels of proinflammatory cytokines and chemokines. METHODS In this retrospective analysis of archived endoscopic samples from responding patients enrolled in the above-mentioned trial, we were interested in studying mucosal gene expression of the pleiotropic proinflammatory cytokines (interleukin-1beta, interleukin-6), TH1 cytokines (interferon-gamma, tumor necrosis factor-alpha, interleukin-12), regulatory cytokines (interleukin-10, transforming growth factor-beta), and the chemokine interleukin-8. In addition to assessment of cytokine gene expression, the presence of polymorphonuclear cells in the mucosal tissue was evaluated. RESULTS Data show that patients who were treated with probiotics had significant lower mucosal mRNA expression levels of interleukin-1beta, interleukin-8, and interferon-gamma compared with placebo-treated patients. In addition, a lower number of polymorphonuclear cells was present in the tissue of patients within the probiotic group compared with the number of polymorphonuclear cells in the tissue of patients receiving placebo and patients having an episode of pouchitis. CONCLUSIONS These data suggest that probiotic treatment regulates the mucosal immune response by reducing mucosal levels of neutrophil-chemoattractant IL-8 and tissue influx of polymorphonuclear cells, and may further act by inhibition of T-cell activation, by reinforcement of barrier function and by a tight control of the potent pro-inflammatory cytokine IL-1beta.

Abstract
Pouchitis, a non-specific inflammation of the ileal reservoir, is the most frequent long-term complication after pouch surgery for ulcerative colitis. Incidence rates vary widely. The etiology is still unknown, but genetic susceptibility and fecal stasis with bacterial overgrowth seem to be important factors. A clinical diagnosis should be always confirmed by endoscopy and histology, and Pouchitis Disease Activity Index (PDAI), based on clinical symptoms, endoscopic appearance and histologic findings, represents an objective and reproducible scoring system for pouchitis. The treatment of pouchitis is largely empiric given the few controlled studies available. Antibiotics, especially metronidazole and ciprofloxacin, are the therapy of choice. Chronic pouchitis occurs in about 10-15% of patients; in these cases, further diagnostic tests should be performed to exclude alternative diagnoses. Highly concentrated probiotics (VSL#3) have been shown to be effective in preventing the onset and relapse of pouchitis.

Abstract
About two-thirds of patients with ulcerative colitis have an inflammatory involvement distal to the splenic flexure, and therefore may be effectively treated with topical treatment, allowing the delivery of the active drug directly to the site of inflammation and limiting systemic absorption and potential side-effects. Topical aminosalicylate therapy is the most effective approach, and most patients will benefit hugely, provided that the formulation reaches the upper extent of the disease. Therefore, the choice of topical preparation should be based on the proximal extent of the disease and on patient preference. Oral aminosalicylates are less effective than topical therapies; however, a combination of oral and topical aminosalicylates can be successful in refractory patients. Alternatives to aminosalicylates are the new glucocorticoids, budesonide and beclometasone dipropionate, either as enemas or oral formulations (only beclometasone dipropionate). A combination of oral or rectal new glucocorticoids with rectal aminosalicylates should be considered in patients refractory to either approach. When these measures fail, treatment with oral glucocorticoids is necessary. An intensive intravenous steroid regimen is also helpful for patients refractory to oral steroids. Alternative treatments include short-chain fatty acid enemas, nicotine enemas and patches, acetarsol suppositories, ciclosporin enemas and epidermal growth factor enemas. Several factors potentially having a negative impact on therapeutic response include concurrent enteric pathogens, coexistent irritable bowel syndrome, patient nonadherence to therapy, inadequate dosing and duration of therapy, and proximal progression of the disease. Surgical colectomy may be required in those rare patients refractory or intolerant to pharmacotherapy.

Abstract
Ulcerative colitis (UC) is an idiopathic, chronic inflammation of the colon which may present with a range of mild to severe symptoms. The disease may be localized to the rectum or can be more extensive and involve the left side of the colon or the whole colon. Treatment in UC is directed towards inducing and maintaining remission of symptoms and mucosal inflammation. The key parameters to be assessed for the most appropriate treatment are the severity and extent of the inflammation. Meta-analyses of published trials have shown that topical treatment with 5-aminosalicylic acid (5-ASA) is the treatment of choice in active distal mild-to-moderate UC. Oral aminosalicylates are effective in both distal and extensive mild-to-moderate disease, but in distal disease, the rates of remission are lower than those obtained with topical 5-ASA. New steroids, such as budesonide and beclomethasone dipropionate (BDP), administered as enemas, constitute an alternative to 5-ASA therapy. In some studies, these have been shown to be as effective as conventional steroids but with significantly lower inhibition of plasma cortisol levels. Patients with unresponsive disease or those with more severe presentation will require oral corticosteroids and sometimes intravenous therapy. Approximately 10% of patients with unresponsive UC have severe attacks requiring hospitalization. Patients with severe disease should be managed jointly by a medical and surgical team, and intensive intravenous treatment should be started with high-dose steroids. Early recognition of failure of therapy will allow the introduction of immunosuppressive therapy with intravenous cyclosporine. Patients who respond are shifted to oral cyclosporine associated with azathioprine/6-mercaptopurine, whereas those who fail will require proctocolectomy. Oral aminosalicylates are the first-line therapy in maintenance of remission. Topical 5-ASA may play a role in distal disease. Patients who are steroid dependent can be started on azathioprine or 6-mercaptopurine although it may take up to 3 months for the treatment to become effective. They may have reversible immediate side effects, such as pancreatitis or bone marrow suppression, which disappear upon discontinuation of therapy. Close monitoring of these hematologic and biochemical parameters will improve safety. The use of biologic therapy with infliximab in more severe disease has not been established.

Abstract
The aetiology of inflammatory bowel disease is still unclean. Whilst a specific pathogen agent associated with these diseases has not been found, the rationale for probiotic therapy in inflammatory bowel disease is based on convincing evidence involving intestinal bacteria in their pathogenesis. Encouraging results have been obtained with probiotic therapy in several animal models of experimental colitis. The administration of highly concentrated probiotic preparations represents a valid approach both for the prevention of pouchitis onset and relapses. The encouraging results obtained in ulcerative colitis and Crohn's disease need to be further assessed in large double-blind trials.

Abstract
Refractoriness to conventional therapy is a common and intriguing problem in Crohn's disease patients. At the present time there is no agreement on its definition and several mechanisms are involved in its determination. Immunosuppressors, such as azathioprine (AZA), 6-mercaptopurine (6MP) and methotrexate (MTX) are effective drugs for controlling the inflammatory process and avoid chronic glucocorticosteroid treatment and its related side-effects. Recently, the introduction of tumour necrosis factor antibodies (infliximab) has dramatically changed the natural history of Crohn's disease and its therapeutic approach. Several studies have determined the efficacy, mechanisms and safety of infliximab. However, this molecular approach has also left several questions unanswered about the mechanisms of refractoriness, possible concomitant treatments and long-term safety and efficacy.
