ABSTRACT
In this review we focused on the putative therapeutic effect of Hericium erinaceus extract in the treatment of pathologic conditions of the lower urinary tract in which intestinal inflammation may play a role. To this aim we reviewed the available evidence on pelvic cross-organ sensitization as a possible mechanism through which intestinal inflammation and dysbiosis may affect the lower urinary tract. Also, we reviewed the clinical and experimental evidence supporting the role of Hericium erinaceus extract as an anti-inflammatory agent highlighting the role of a number of putative mediators and mechanisms which might make this nutraceutical suitable for the management of 'difficult to treat' lower urinary tract disorders.

BACKGROUND: Percutaneous Endoscopic Gastrostomy (PEG) can involve some complications, despite the good safety of its track record. The Buried Bumper Syndrome (BBS) is a rare, late and dangerous complication that consists in the erosion of the internal bumper through the gastric wall. Case presentation We report the development of BBS in a man with chronic obstructive pulmonary disease (COPD) who had a persistent chronic cough which was prevalently but not solely in the morning and required placement of a PEG tube for continuous infusion of Levodopa/carbidopa intestinal gel for advanced Parkinson's disease. CONCLUSION: We believe that COPD with chronic cough while not representing an absolute contraindication to PEG placement, may potentially cause BBS and therefore an appropriate regimen of tube care by expert personnel is mandatory in this setting.

Ustekinumab (UST), a human anti-IL12/23p40 monoclonal antibody, was approved by FDA and EMA for the treatment of moderate to severe Crohn's disease (CD). Whether UST is effective in inducing deep remission, including mucosal healing and transmural healing, in patients with CD in a real life setting is not completely clear. This study was performed on 92 subjects with confirmed diagnosis of moderate to severe Crohn's disease and no neoplasia. Before inclusion, all patients had been exposed and had failed to respond to conventional and/or at least one biological therapy. All patients underwent endoscopic examination and bowel MRI and ultrasonography at baseline (T0). At week 52 (T52), patients underwent colonoscopy for assessment of mucosal healing and MRI or ultrasonography for assessment of transmural healing. CDAI was used for the assessment of clinical response and clinical remission. SES-CD was used to assess endoscopic response and remission. Incidence of treatment-related adverse events (TRAEs) was recorded during the study period. Clinical response at week 52 was achieved in 38 (50.5%) patients and clinical remission in 29 (39%). Twenty-six (34%) patients showed mucosal healing, 34 (45%) showed partial endoscopic response. We observed a reduction in SES-CD of at least 50% in 34 (45%) patients as well as an SES-CD ≤ 2 in 26 (35%) patients. All patients with mucosal healing also showed transmural healing. No major TRAEs were observed during treatment. In this multicenter, real life study, we show that UST was well tolerated and effective in inducing clinical response and clinical remission in patients with moderate to severe CD who had previously failed to respond to conventional or biologic therapy. UST showed limited efficacy in inducing deep remission (i.e. mucosal+transmural healing).

BACKGROUND AND AIMS: Hp(2-20), a Helicobacter pylori-derived peptide interacting with N-formyl peptide receptors (FPRs), accelerates the healing of gastric injury in rats. Whether Hp(2-20) affects the recovery of inflamed colonic mucosa is unknown. We evaluated whether Hp(2-20) accelerated the healing of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis and explored the mechanism(s) underlying any such effect. METHODS: Fifteen rats underwent rectal administration of Hp(2-20) 250-500 µg/kg/day, or of its control peptide Hp1 for 10 days, following induction of colitis with TNBS. Macroscopic and histological damage was quantified using predetermined injury scores. FPR1, COX-2, TNF-α, TGF-ß, HB-EGF and tissue transglutaminase (t-TG) messenger RNA (mRNA) expression in colonic tissue was determined by quantitative polymerase chain reaction; FPR1, TNF-α and COX-2 protein levels by Western blotting. RESULTS: (1) Hp(2-20) accelerated healing of TNBS-induced colitis compared to controls consistently with the expression of FPRs in colonic mucosa; (2) TNBS upregulated mRNA mucosal expression of COX-2, TNF-α, TGF-ß, HB-EGF and t-TG and (3) this, with the exception of HB-EGF, was significantly counteracted by Hp(2-20). CONCLUSIONS: Hp(2-20), an FPR agonist, accelerates the healing of TNBS-induced colitis in the rat. This effect is associated with a significant reduction in colonic tissue levels of COX-2, TGF-ß, TNF-α and t-TG. We postulate that FPR-dependent pathways may be involved in the repair of inflamed colonic mucosa.
ABSTRACT
BACKGROUND: Bisphenol A is an endocrine disrupting chemical associated with type 2 diabetes mellitus (T2DM), cardiovascular disease and liver enzyme abnormalities. AIM: To evaluate bisphenol A plasma and urine levels in non-alcoholic fatty liver disease (NAFLD) patients compared to healthy subjects. Furthermore, we evaluated, in human HepG2 cells, the effects of exposure to different concentrations of bisphenol A on both oxidative stress induction and cell proliferation. METHODS: We enrolled 60 patients with histological diagnosis of NAFLD with or without T2DM and sixty healthy subjects. In vitro, the proliferation of bisphenol A-exposed HepG2 cells at two different concentrations (0.025 and 0.05 µM) was evaluated, both at high (H-HepG2) and at low (L-HepG2) glucose concentrations for 48 h. Lipoperoxidation was assessed by thiobarbituric acid reactive substances (TBARS) assay. RESULTS: Bisphenol A levels were significantly higher in 60 NAFLD subjects, both in urine and in plasma (P < 0.0001) when compared to controls and, in this group, it appeared to be higher in 30 non-alcoholic steatohepatitis patients compared to 30 simple steatosis subjects (P < 0.05), independently from the presence of T2DM. After a bisphenol A-free diet for 1 month, NAFLD patients showed a significant reduction in bisphenol A circulating levels (P < 0.05), without a significant reduction in urine levels. H-HepG2 cells treated with bisphenol A (0.05 µM) increased proliferation compared to controls at 48 h (P < 0.0001). Bisphenol A increased TBARS levels at 48 h versus controls. CONCLUSIONS: Our study reveals a possible role of bisphenol A as an environmental factor involved in the promotion of NAFLD, particularly in T2DM patients.

Crohn's disease is a chronic inflammatory bowel disease potentially involving any segment of the gastrointestinal tract. Extra-intestinal manifestations may occur in 6%-40% of patients, and disorders of the skin are among the most common. This manuscript will review skin manifestations associated to Crohn's disease, with a particular focus on lesions associated to anti-tumour necrosis factor therapy.
ABSTRACT
Zeolites are microscopic minerals of volcanic origin, and the zeolite most commonly used in medicine is clinoptilolite. Over the years, clinoptilolite has been tested in several ways: as an antioxidant, as an adjuvant in anticancer therapy due to its ability to capture chemotoxins, as an antidiarrhoeal agent and as a chelating agent for heavy metals. The aim of this study was to evaluate the ability of clinoptilolite to absorb ethanol in vivo in healthy drinkers. We enrolled 12 healthy drinkers in this study. The study was conducted as follows: phase 1: consumption of a hydroalcoholic solution containing 25 g of ethanol; phase 2: use of a 16.25 mL medical device containing clinoptilolite (2.5 g of clinoptilolite within a single-dose sachet) + consumption of a hydroalcoholic solution containing 25 g of ethanol; phase 3: use of a 32.5 mL medical device (5 g of clinoptilolite within a single-dose sachet) + consumption of a hydroalcoholic solution containing 25 g of ethanol. At the time of blood sampling, alcohol ingestion was also measured using an Alcolmeter instrument, and the results showed that the two methods overlapped. Reductions of 43%, 35%, 41% and 34% in blood ethanol at 30, 60, 90 and 120 minutes, respectively, were observed after the consumption of 5 g of clinoptilolite + 25 g of ethanol in both males and females, whereas the consumption of 2.5 g of clinoptilolite did not result in a statistically significant reduction in blood ethanol. In particular, the blood ethanol reduction was more significant in males. Our study highlights and confirms the ability of clinoptilolite to decrease the absorption of ingested ethanol by reducing blood alcohol levels. This effect was statistically significant at a dose of 5 g.

BACKGROUND: The most commonly used second-line Helicobacter pylori eradication regimens are bismuth-containing quadruple therapy and levofloxacin-containing triple therapy, both offering suboptimal results. Combining bismuth and levofloxacin may enhance the efficacy of rescue eradication regimens. AIMS: To evaluate the efficacy and tolerability of a second-line quadruple regimen containing levofloxacin and bismuth in patients whose previous H. pylori eradication treatment failed. METHODS: This was a prospective multicenter study including patients in whom a standard triple therapy (PPI-clarithromycin-amoxicillin) or a non-bismuth quadruple therapy (PPI-clarithromycin-amoxicillin-metronidazole, either sequential or concomitant) had failed. Esomeprazole (40 mg b.d.), amoxicillin (1 g b.d.), levofloxacin (500 mg o.d.) and bismuth (240 mg b.d.) was prescribed for 14 days. Eradication was confirmed by (13) C-urea breath test. Compliance was determined through questioning and recovery of empty medication envelopes. Incidence of adverse effects was evaluated by questionnaires. RESULTS: 200 patients were included consecutively (mean age 47 years, 67% women, 13% ulcer). Previous failed therapy included: standard clarithromycin triple therapy (131 patients), sequential (32) and concomitant (37). A total of 96% took all medications correctly. Per-protocol and intention-to-treat eradication rates were 91.1% (95%CI = 87-95%) and 90% (95%CI = 86-94%). Cure rates were similar regardless of previous (failed) treatment or country of origin. Adverse effects were reported in 46% of patients, most commonly nausea (17%) and diarrhoea (16%); 3% were intense but none was serious. CONCLUSIONS: Fourteen-day bismuth- and levofloxacin-containing quadruple therapy is an effective (≥90% cure rate), simple and safe second-line strategy in patients whose previous standard triple or non-bismuth quadruple (sequential or concomitant) therapies have failed.

BACKGROUND: Alcohol consumption by adolescents and young adults is an issue of significant public concern. Internet-based Social Networking sites, such as Facebook, are potential avenues to reach young people easily. OBJECTIVE: to underline the innovation in proposing surveys to collect health-related information regarding young people alcohol consumption and other substances abuse by using Social Networking Websites, particularly Facebook. METHODS: A questionnaire investigating modalities of alcohol consumption, drinking patterns' risk behaviors and other substances abuse was proposed through a "Facebook event" to young Italian Facebook users aged between 16 and 32. Each Facebook user invited to the event was free to participate, to answer to the questionnaire and to invite his "Facebook friends". RESULTS: During the 89 days of permanence on the Social Network, 1846 Facebook users participated the event and 732 of them decided spontaneously to answer the questionnaire. The frequency of answering was 8.2 people per day. About 200 users wrote a positive comment to the initiative on the wall of the event. Sixty% of subjects participating the survey were females. Ninety-one% of people answering the questionnaire were alcohol consumers. More than 50% of alcohol consumers were also smokers. Approximately 50% of subjects were binge drinkers. Illegal drugs were used by the 22.2% of the interviewed people. CONCLUSIONS: Facebook resulted an efficient and rapid tool to reach young people from all over Italy and to propose surveys in order to investigate alcohol consumption and alcohol-related health problems in the youth.

Pyoderma gangrenosum is a rare, ulcerative, cutaneous condition. First described in 1930, the pathogenesis of pyoderma gangrenosum remains unknown, but it is probably related to a hyperergic reaction. There are various clinical and histological variants of this disorder. Pyoderma gangrenosum often occurs in association with a systemic disease such as inflammatory bowel disease, rheumatologic disease, paraproteinaemia, or haematological malignancy. The diagnosis, mainly based on the clinical presentation and course, is confirmed through a process of elimination of other causes of cutaneous ulcers. Local treatment may be sufficient for mild disease, while for severe cases, systemic immunosuppressants are the mainstay. Long-term treatment with these agents is often required, but this can expose patients to adverse side-effects.

Ulcerative colitis may be associated with a number of skin lesions such as erythema nodosum and pyoderma gangrenosum. We here describe an unusual case of a 33-year-old-caucasian male with ulcerative colitis and skin lesions diagnosed as leukocytoclastic vasculitis. An initial treatment with oral deflazacort led to little benefit, while treatment with oral mesalazine caused remission of the skin and intestinal manifestations in 2 weeks.
