Abstract
Background ad aim of workː the position of Italian law regarding participation of prophylactically treated hemophiliacs to organized sport trainings and competitions remains unclear and this study focuses on the eligibility of pediatric patients in particular. Methodsː 16 patients age 3 to 15 years old, with severe haemophilia and prophylaxis starting age of 20,2 ± 2,2 months were enrolled. Weight, height, body mass index (BMI) and joint status (Hemophilia Joint Health Score [HJHS] and Haemophilia Early Arthropathy Detection with UltraSound, HEAD-US score) of patients were evaluated at start (T0) and after 12 months (T12) of a HIITS sport activity program. Resultsː All patients qualified for Italian competitive sport medical certification. Their weight and height increased after 12 months, without an increase in BMI (T0= 17,2; T1= 18,7; p>0,05). HJHS score did not change significantly (T0: 1.6 ± 1; T1: 2.1 ± 1.3; p>0.05). All children were right-handed and atrophy for the muscles of the right elbow significantly decreased (no atrophy seen at T0 in 4 of 16 patients and at T1 in 8 of 16 patients; p=0.045). Conclusionsː Hemophilic children, prophylactically treated, are capable to be included in sport groups and physical activity programs.

Abstract
Hemophilias are hemorrhagic congenital rare diseases. The gold standard of therapy in hemophilics is the intravenously replacement therapy. We can infuse intravenously plasma derived factors (FVIII for Hemophilia A and FIX for Hemophilia B) or recombinant products (i.e. clotting factor synthetically produced). Venipuncture is not a safe procedure in subjects with hemorrhagic diseases. It is considered an invasive technique with potential massive bleeding and it requires standardized procedures to prevent complications. Local pressure after the procedure (with eventually ice rest) must be always done. In case of bleeding a rapid replacement therapy must be conducted. A severe complication in hemophilia is compartment syndrome. We report a case of massive bleeding in a hemophilic newborn after venipuncture and a literature review of compartment syndrome in hemophiliacs. The aim of this paper is to help physicians in the clinical management to prevent the evolution of a massive bleeding in compartment syndrome.

Abstract
BACKGROUND MiRNAs are a class of small non-coding RNAs that are involved in the post-transcriptional regulation of gene expression. MiRNAs are considered a class of epigenetic biomarkers. These biomarkers can investigate disease at different stages: diagnosis, therapy or clinical follow-up. OBJECTIVE The aim of this paper is to highlight the innovative use of miRNAs in several childhood diseases. METHODS We conducted a literature review to search the usage of miRNAs in pediatric clinical routine or experimental trials. RESULTS We found a possible key role of miRNAs in different pediatric illnesses (metabolic alterations, coagulation defects, cancer). CONCLUSION The modest literature production denotes that further investigation is needed to assess and validate the promising role of miRNAs as non-invasive biomarkers in pediatric disorders.

Abstract
In a previously published double-blind, placebo-controlled study, we showed that probiotics intake exerted a positive effect on sleep quality and a general improvement across time in different aspects of the profile of mood state, like sadness, anger, and fatigue in 33 healthy individuals. The present work investigates the impact of the probiotic product, constituted of Limosilactobacillus fermentum LF16, Lacticaseibacillus rhamnosus LR06, Lactiplantibacillus plantarum LP01 (all former members of Lactobacillus genus), and Bifidobacterium longum 04, on the gut microbiota composition of the same cohort through a metabarcoding analysis. Both the placebo and probiotic treatments had a significant impact on the microbiota composition. Statistical analysis showed that the microbiota of the individuals could be clustered into three groups, or bacteriotypes, at the baseline, and, inherently, bacterial compositions were linked to different responses to probiotic and placebo intakes. Interestingly, L. rhamnosus and L. fermentum were retrieved in the probiotic-treated cohort, while a bifidogenic effect of maltodextrin, used as placebo, was observed. The present study shed light on the importance of defining bacteriotypes to assess the impact of interventions on the gut microbiota and allowed to reveal microbial components which could be related to positive effects (i.e. sleep quality improvement) to be verified in further studies.

Abstract
OBJECTIVE Immune thrombocytopenia (ITP) is an acquired immuno-mediated disorder characterized by thrombocytopenia with an increased risk of bleeding. In recent years 1,25[OH]2D3 has been rediscovered as an immune modulator. We decided to evaluate serum Vitamin D levels in a cohort of children with immune thrombocytopenia in order to discover if Vitamin D concentrations may predict ITP duration. METHODS Thirty children were enrolled in this study (sixteen with chronic ITP and fourteen with newly diagnosed ITP) to assess serum Vitamin D levels. RESULTS The results showed that 80% of the enrolled children presented a D hypovitaminosis status. Children with newly diagnosis ITP showed no statistically significantly higher median values of Vitamin D compared to chronic ITP. CONCLUSION This study may suggest that Vitamin D deficiency does not represent a chronicity factor for ITP. However, further studies are needed to understand the role of Vitamin D in ITP pathogenesis.

Abstract
Venous thromboembolism (VTE) in children is a rare occurrence, although in recent decades we have seen an increase due to several factors, such as the rise in survival of subjects with chronic conditions, the use of catheters, and the increased sensitivity of diagnostic tools. Besides inherited thrombophilia, acquired conditions such as cardiovascular diseases, infections, chronic disorders, obesity and malignancy are also common risk factors for paediatric VTE. The treatment of paediatric VTE consists of the use of heparins and/or vitamin K antagonists to prevent dissemination, embolization, and secondary VTE. Randomized clinical trials of direct oral anticoagulants in paediatric VTE are ongoing, with the aim to improve the compliance and the care of patients. We reviewed the physiological and pathological mechanisms underlying paediatric thrombosis and updated the current diagnosis and treatment options.

Abstract
Human coronaviruses (HCoVs) commonly cause mild upper-respiratory tract illnesses but can lead to more severe and diffusive diseases. A variety of signs and symptoms may be present, and infections can range in severity from the common cold and sore throat to more serious laryngeal or tracheal infections, bronchitis, and pneumonia. Among the seven coronaviruses that affect humans (SARS)-CoV, the Middle East respiratory syndrome (MERS)-CoV, and the most recent coronavirus disease 2019 (COVID-19) represent potential life-threatening diseases worldwide. In adults, they may cause severe pneumonia that evolves in respiratory distress syndrome and multiorgan failure with a high mortality rate. Children appear to be less susceptible to develop severe clinical disease and present usually with mild and aspecific symptoms similar to other respiratory infections typical of childhood. However, some children, such as infants, adolescents, or those with underlying diseases may be more at-risk categories and require greater caution from clinicians. Available data on pediatric coronavirus infections are rare and scattered in the literature. The purpose of this review is to provide to clinicians a complete and updated panel useful to recognize and characterize the broad spectrum of clinical manifestations of coronavirus infections in the pediatric age.

Abstract
BACKGROUND A link between small intestinal bacterial overgrowth (SIBO) and celiac disease (CD) has been hypothesized. METHODS Literature search was performed in main medical databases. Methods of analysis/inclusion criteria were based on Preferred Reporting Items for Systematic reviews and Meta-Analyses recommendations. The end-point was to estimate, by a pooled-data analysis, SIBO prevalence in CD. Proportions/percentages and their 95% confidence intervals (CI) were calculated by inverse variance method, whereas odd ratios (OR) and their 95% CI were estimated, where available, based on the Mantel-Haenszel method. Data were entered into the RevMan 5.3 software. KEY RESULTS Eleven articles fulfilled considered criteria. The pooled mean prevalence of SIBO in CD was 20% (95% CI of 10%-30%). In comparison to asymptomatic controls, CD was associated to higher risk of SIBO, with an OR of 10.52 (95% CI 2.69-41.21, P=.0007). Jejunal aspirate culture assessed SIBO prevalence of 11% (95% CI 3%-19%) in CD, whereas breath tests detected a higher value (23%, 95% CI 10%-37%). The pooled prevalence of SIBO in CD patients who were symptomatic despite a GFD was 28% (95% CI 10%-47%), higher than in asymptomatic celiac patients (pooled prevalence of 10%, with a 95% CI of 3%-16%), despite not statistically significant (P=.06). When GFD-unresponsive CD was defined only by clinical persistence of symptoms, the prevalence of SIBO was higher than in the case of villous atrophy association (31% vs 16% P=.33). CONCLUSIONS The heterogeneity of available studies may not support a relationship SIBO-CD. Nevertheless, SIBO could be more common in CD when symptoms do not improve after GFD.

Abstract
BACKGROUND It is unclear whether the efficacy and long-term outcome of treating patients with hepatitis C virus (HCV)-positive cirrhosis with the new protease inhibitors will extend to those with Child C cirrhosis. AIM To assess the effectiveness of the interferon-free regimens in Child C cirrhotic patients with HCV infection. METHODS A systematic Medline search was conducted to retrieve studies describing the treatment of Child C patients with direct-acting agents. Citations from identified studies were cross-referenced and abstracts from European Association for the Study of the Liver (EASL) and American Association for the Study of Liver Disease (AASLD) meetings were checked. Extracted data were evaluated using a meta-analysis to calculate a weighted response rate. RESULTS Seven full-text records and two conference abstracts were retained for analysis from the 649 records identified. Data from an Italian real-life trial were also interrogated. Information on treatment outcome was available for 228 of the 240 Child C patients evaluated in the 10 trials. Overall, the weighted mean sustained virological response (SVR12) was 74.9% (95% CI: 65.6-82.4%). Neither duration of treatment (24 or 12 weeks), nor addition of ribavirin influenced these rates. The weighted SVR12 was 65.4% (95% CI: 46.8-80.2) after sofosbuvir/simeprevir, 76.0% (95% CI: 54.4-89.3%) after sofosbuvir/daclatasvir and 83.0% (95% CI: 73.4-89.6) after sofosbuvir/ledipasvir. Some studies did not provide information on the rate of post-treatment relapse or functional improvement. However, in those studies that did provide such data, a relapse was documented in 12.1% of patients and an improvement of ≥2 points on the model for end-stage liver disease (MELD) score in 61.1% of patients. CONCLUSION The improvement in MELD scores strongly suggests HCV-positive patients with Child C cirrhosis should be treated with these agents.

Abstract
Oral antibiotics, especially tetracyclines, are commonly used to treat moderate to moderately severe acne vulgaris. There are hints suggesting that a combination treatment with oral tetracyclines and topical retinoids can cause a greater and prompter improvement of acne than monotherapy with tetracyclines. We evaluated the clinical activity of a 12-week combined therapy with oral lymecycline (300mg/day for 2 weeks and then 150mg/day) and topical adapalene (gel or cream) in 419 patients with inflammatory acne. A significant reduction in the number of acne lesions was noted at 4 and 12 weeks (P<0.0001). Thereafter, 400 patients underwent a maintenance treatment with adapalene alone for 12 weeks. At week 24 a relevant improvement of acne lesions still persisted (P<0.0001) in most patients. Only 16 patients relapsed and required additional use of oral lymecycline which proved again successful. No substantial differences were noted in the magnitude of clinical response between patients treated with adapalene gel and those treated with cream formulation. Treatment was well tolerated. Local adverse reactions occurred in 11.7 % of patients and resulted in premature discontinuation of treatment in 1.4 %. Systemic (gastrointestinal) untoward effects developed in 1.2 % of patients and caused treatment interruption in 0.7 % of cases. No serious adverse events occurred.

Abstract
Tumour necrosis factor (TNF)-alpha plays an important role in the pathogenesis of psoriasis. Infliximab is an anti-TNF-alpha chimeric monoclonal antibody, which is licensed for the treatment of rheumatoid arthritis and Crohn's disease. Some reports have shown the efficacy of infliximab, either in monotherapy or in combination with methotrexate, for the treatment of psoriatic arthropathy and psoriasis. The efficacy and tolerability of infliximab monotherapy was evaluated in 29 patients with moderate to severe psoriasis, unresponsive to conventional treatments. Fourteen patients suffered from concomitant arthropathy. Patients received intravenous infliximab, 5mg/kg, at weeks 0, 2, and 6. After this 3-dose-induction regimen, patients were followed-up at monthly intervals and retreated with a single-dose infusion in case of relapse of signs and symptoms. Clinical assessment was performed using the psoriasis area and severity index (PASI) to monitor psoriasis activity; pruritus and joint pain were assessed on a scale of 0 to 3. A marked improvement of skin lesions and subjective symptoms was noted in the majority of patients; an excellent reduction of PASI score (⩾75%) was observed in 13.8% of cases at week 2, 71.4% at week 6 and 78.6% at week 10. During the follow-up period, some patients maintained satisfactory clinical results without requiring any additional infusions. In general, skin lesions showed a trend towards a more prolonged and sustained improvement as compared with subjective symptoms. Treatment was well tolerated and no serious adverse events occurred.

Abstract
BACKGROUND/OBJECTIVES There are conflicting data on the effect of a gluten-free diet (GFD) on the nutritional status of celiac patients. In the present study, we evaluated, in adult celiac patients, the influence of a long-term, strictly GFD on their nutritional status and compared it with matched healthy volunteers. SUBJECTS/METHODS Our study included 39 celiac patients and 39 healthy volunteers. The body mass index (BMI) of patients and controls was evaluated at enrollment, while the patients' BMI before the GFD was retrieved from clinical records. In addition, at enrollment, in both groups, we compared BMI, fat mass (FM), bone mineral density (BMD), as well as their dietary intake, recorded on a 7-day diary. RESULTS At the time of diagnosis, the majority of celiac patients (82.0%) had a normal BMI or were overweight, while 10.3% were malnourished. After the GFD, patients with a normal BMI showed a significant weight increase (P=0.002), but none of them switched in the overweight or obese category. Two (50%) of the four malnourished patients achieved a normal BMI. Controls and patients on a GFD had a similar BMI, FM, BMD and total calorie intake, but the amount of lipids and fiber intake was significantly different in the two groups (P=0.003 and P<0.0001, respectively). CONCLUSIONS Our study demonstrates that a GFD is able to improve the nutritional status of celiac patients without inducing overweight or obesity. Our findings are related to a celiac population adopting a GFD based on a Mediterranean-type diet.

Abstract
BACKGROUND AND PURPOSE Microparticles (MPs), small membrane-bound particles originating from different cell types during activation or apoptosis, mediate intercellular communication, exert pro-coagulant activity and affect inflammation and other pathophysiological conditions. Monocyte-derived MPs have undergone little investigation and, to our knowledge, have never been evaluated for their possible autocrine effects. Therefore, we assessed the ability of monocyte-derived MPs to stimulate human monocytes and monocyte-derived macrophages (MDM). EXPERIMENTAL APPROACH MPs were generated from supernatants of human monocytes stimulated by the calcium ionophore A23187 (12 µM), and then characterized. Human monocytes and MDM of healthy donors were isolated by standard procedures. Cells were challenged by MPs or phorbol 12-myristate 13-acetate (PMA, used as standard stimulus), in the absence or presence of PPARγ agonists and antagonists. Superoxide anion production (measured spectrophotometrically), cytokine release (elisa), PPARγ protein expression (immunoblotting) and NF-κB activation (EMSA assay) were evaluated. KEY RESULTS Monocyte-derived MPs induced, in a concentration-dependent manner, oxygen radical production, cytokine release and NF-κB activation in human monocytes and macrophages, with lower effects than PMA. In both cell types, the PPARγ agonists rosiglitazone and 15-deoxy-Δ(12,14) -prostaglandin J(2) (15d-PGJ(2) ) inhibited MPs-induced stimulation and this inhibition was reversed by a PPARγ antagonist. In human monocyte/macrophages, MPs as well as rosiglitazone and 15d-PGJ(2) induced PPARγ protein expression. CONCLUSION AND IMPLICATIONS In human monocyte/macrophages, monocyte-derived MPs exert an autocrine activation that was modulated by PPARγ ligands, inducing both pro-inflammatory (superoxide anion production, cytokine release and NF-κB activation) and anti-inflammatory (PPARγ expression) effects.

Abstract
AIM Despite an obvious need for rehabilitative treatment, some parents deny consent and some others withdraw their children from a previously accepted program. There is limited literature concerning how to prevent this, serving the child's best interest, and the existing is mainly focused on legal implications. METHODS This was a naturalistic study, carried out using data obtained during the diagnostic evaluation of 166 children (all those seen in the Child Neuropsychiatry Unit). For 25 children (15.1%), parents refused or interrupted suggested treatment. RESULTS Statistical analysis showed that there is a significant difference in terms of impairment in children of parents accepting or refusing the rehabilitative treatment. Treatment discontinuation is related to the diagnosis (higher percentage in severe language disorders or complex developmental disorders), higher reduction in global functioning, higher disability burden, need for integrated treatment, lower age. CONCLUSIONS Findings of this study could be useful in order to better plan rehabilitative options and goals. It is possible that an attempt to increase parental involvement in the rehabilitative program could lead to a decrease in treatment discontinuation. Anyway, more research is needed because we are still far from having a good predictive model to anticipate and, if possible, avoid treatment discontinuation.

Abstract
BACKGROUND AND PURPOSE Tobacco smoke represents a relevant risk factor for coronary heart disease (CHD). Although peroxisome proliferator-activated receptor (PPAR)gamma activation reduces inflammation and atherosclerosis, expression of PPARgamma in cells and its modulation by smoking are poorly investigated. We previously reported that monocyte/macrophages from healthy smokers exhibited an enhanced constitutive expression of PPARgamma. Here, we evaluated PPARgamma expression and basal cytokine release in monocytes and monocyte-derived macrophages (MDMs) from 85 CHD patients, classified by their smoking habit (smokers, non-smokers and ex-smokers), and assessed the role of PPARgamma ligands in this context. EXPERIMENTAL APPROACH PPARgamma protein was detected by Western blot and semi-quantified by PPARgamma/beta-actin ratio; cytokine release was measured by elisa and nuclear factor-kappaB (NF-kappaB) translocation by electrophoretic mobility shift assays. KEY RESULTS As compared to the other groups, MDMs from smoker CHD patients exhibited a reduced PPARgamma/beta-actin ratio and an increased spontaneous release of tumour necrosis factor-alpha (TNF-alpha) and interleukin-6, but with no major variations in monocytes. In cells from selected CHD patients, rosiglitazone inhibited TNF-alpha release and NF-kappaB translocation induced by phorbol-12-myristate 13-acetate. The selective PPARgamma antagonist GW9662 reversed these effects, with some variations related to smoking habit. CONCLUSIONS AND IMPLICATIONS In CHD patients, exposure to tobacco smoke profoundly affected PPARgamma expression, and this was related to levels of secretion of pro-inflammatory cytokines. MDMs from CHD smokers showed the lowest PPARgamma expression and released more inflammatory cytokines. Moreover, rosiglitazone's ability to inhibit cytokine release and its reversal by GW9662 clearly indicated PPARgamma involvement in these changes in CHD patients.

Abstract
BACKGROUND AND PURPOSE Phenolic compounds exert cytoprotective effects; our purpose was to investigate whether the isosteric polyphenolic compounds clovamide and rosmarinic acid are neuroprotective. EXPERIMENTAL APPROACH Three in vitro models of neuronal death were selected: (i) differentiated SH-SY5Y human neuroblastoma cells exposed to tert-butylhydroperoxide (t-BOOH), for oxidative stress; (ii) differentiated SK-N-BE(2) human neuroblastoma cells treated with L-glutamate, for excitotoxicity; and (iii) differentiated SH-SY5Y human neuroblastoma cells exposed to oxygen-glucose deprivation/reoxygenation, for ischaemia-reperfusion. Cell death was evaluated by lactate dehydrogenase measurements in the cell media, while the mechanisms underlying the effects by measuring: (i) t-BOOH-induced glutathione depletion and increase in lipoperoxidation; and (ii) L-glutamate-induced intracellular Ca(2+) overload (fura-2 method) and inducible gene expression (c-fos, c-jun), by reverse transcriptase-PCR. The ability of compounds to modulate nuclear factor-kappaB and peroxisome proliferator-activated receptor-gamma activation was evaluated by Western blot in SH-SY5Y cells not exposed to harmful stimuli. KEY RESULTS Both clovamide and rosmarinic acid (10-100 micromol x L(-1)) significantly protected neurons against insults with similar potencies and efficacies. The EC(50) values were in the low micromolar range (0.9-3.7 micromol x L(-1)), while the maximal effects ranged from 40% to -60% protection from cell death over untreated control at 100 micromol x L(-1). These effects are mediated by the prevention of oxidative stress, intracellular Ca(2+) overload and c-fos expression. In addition, rosmarinic acids inhibited nuclear factor-kappaB translocation and increased peroxisome proliferator-activated receptor-gamma expression in SH-SY5Y cells not exposed to harmful stimuli. CONCLUSION AND IMPLICATIONS Clovamide and rosmarinic acid are neuroprotective compounds of potential use at the nutritional/pharmaceutical interface.

Abstract
BACKGROUND AND PURPOSE Substance P (SP) and peroxisome proliferator-activated receptor-gamma (PPAR-gamma) play important roles in different inflammatory conditions and are both expressed in human monocytes and macrophages. However, it is not known whether or not they interact. This study was undertaken to evaluate the effects of SP on PPAR-gamma protein expression in monocytes and macrophages (MDMs: monocyte-derived macrophages) from healthy smokers and non-smokers. EXPERIMENTAL APPROACH PPAR-gamma protein was detected by western blot and quantified by calculating the ratio between PPAR-gamma and beta-actin protein expression. Constitutive tachykinin NK(1) receptor expression in monocytes and MDMs from healthy smokers and non-smokers was evaluated by western blot. Cytokine release was evaluated by ELISA. KEY RESULTS In the concentration range 10(-10)-10(-6) M, SP stimulated PPAR-gamma protein expression in monocytes and MDMs, being more effective in cells from healthy smokers. Moreover, in these cells there was a constitutively increased expression of NK(1) receptors. SP-induced expression of the PPAR-gamma protein was receptor-mediated, as it was reproduced by the NK(1) selective agonist [Sar(9)Met(O(2))(11)]SP and reversed by the competitive NK(1) antagonist GR71251. SP-induced maximal effects were similar to those evoked by 15-deoxy-Delta(12,14)-prostaglandin J(2); an endogenous PPAR-gamma agonist, and were significantly reduced by a PPAR-gamma antagonist. NK(1) and PPAR-gamma agonists exerted opposite effects on TNF-alpha release from monocytes and MDMs. CONCLUSIONS AND IMPLICATIONS Enhancement of PPAR-gamma protein expression represents a novel activity for SP, which could contribute to a range of chronic inflammatory disorders.

Abstract
The purpose of this study was to establish if estrogen-induced hepatocyte proliferation in vitro involves the cell cycle regulators cyclin D1, p21(Cip1), and p27(Kip1). Male rat hepatocytes were cultured in presence of 17-beta-estradiol (E2) +/- ICI-182780, a pure estrogen antagonist, and [3H]-thymidine, as required. DNA synthesis as well as p21(Cip1), p27(Kip1), and cyclin D1mRNA and protein levels were evaluated at different times (12, 24, 36, and 48 hours) of incubation. E2-increased DNA synthesis was correlated with cyclin D1 and p21(Cip1) (mRNA and protein) variations that were reversed by the addition of ICI-182780. p27(Kip1) protein levels progressively increased regardless of the presence of E2 or ICI-182780. Our data confirm that estrogens' stimulatory effect is related to their ability to increase cyclin D1 levels. The increase of p21(Cip1) is probably related to the reentry of hepatocytes in the quiescent state. p27(Kip1) protein is not able to arrest hepatocyte proliferation.

Abstract
BACKGROUND Helicobacter pylori clarithromycin resistance is increasing worldwide and different mutations are involved in its mechanisms. Recently, molecular methods have been proposed to assess these mutations. AIM To assess prevalence of primary clarithromycin resistance in two Italian areas, and the distribution of involved mutations, by using a novel method for real-time polymerase chain reaction. METHODS Two hundred and thirty-two H. pylori-positive patients undergoing oesophagogastroduodenoscopy in two Italian towns (Rome, centre Italy; Foggia, south Italy) were enrolled. Helicobacter pylori infection was detected by histology, rapid urease and urea breath tests. Clarithromycin resistance was assessed by TaqMan real-time polymerase chain reaction on paraffin-embedded antral biopsies. Results Primary clarithromycin resistance was detected in 62 (26.7%) patients. Its prevalence did not differ between the two areas (31.5%, centre vs. 23.3%, south; P=0.17) and between non-ulcer dyspepsia and peptic ulcer patients (28.4% vs. 20.7%, P=0.2). The A2143G point mutation was detected in 35 (56.4%) patients, A2142G in 14 (22.6%), A2142C in eight (12.9%), whilst a double mutation (A2143G plus A2142C or A2142G) was present in the remaining five (8.1%) cases. CONCLUSIONS Our study found that primary clarithromycin resistance is highly prevalent in both central and southern Italy, and that A2143G is the most frequent point mutation involved in these areas.

Abstract
Association between Crohn's disease (CD) and lupus nephritis is very rare and, to the best of our knowledge, it has been described only once. We report here a clinical case of CD occurred in a young woman 8 years after a diagnosis of lupus nephritis according to clinical, laboratory and histological criteria. CD was unresponsive to steroids and immunosuppressants and, therefore, the patient was treated with anti-tumour necrosis factor alpha monoclonal antibody (Infliximab). This therapy led to the remission of both CD (50% of Crohn's Disease Activity Index--CDAI--decrease) and lupus nephritis (disappearance of pyuria in absence of infection, significant increase of serum albumin and improvement of renal function tests). The immunological background of both diseases has to be taken into account to explain either the association of the two disorders or the therapeutic response. Moreover, this clinical case confirms and extends the concept that in patients with CD a more accurate detection of autoimmune associated disorders is required.

Abstract
BACKGROUND A novel 10-day sequential treatment regimen recently achieved a significantly higher eradication rate than standard 7-day therapy in both peptic ulcer disease and non-ulcer dyspepsia. Its higher performance has recently been confirmed using a halved clarithromycin dose in peptic ulcer disease. AIMS To evaluate whether an acceptable eradication rate could also be obtained by halving the clarithromycin dose in dyspeptic patients and to assess the role of possible factors affecting the outcome of therapy. METHODS In a prospective, open-label study, 162 patients with non-ulcer dyspepsia and Helicobacter pylori infection, assessed by rapid urease test and histology, were enrolled. Patients were randomized to receive either 10-day sequential therapy, comprising rabeprazole 20 mg b.d. plus amoxicillin 1 g b.d. for the first 5 days, followed by rabeprazole 20 mg b.d., clarithromycin 250 mg b.d. and tinidazole 500 mg b.d. for the remaining 5 days (low-dose therapy), or a similar schedule with clarithromycin 500 mg b.d. (high-dose therapy). Four to six weeks after therapy, H. pylori eradication was assessed by endoscopy/histology. RESULTS A similar H. pylori eradication rate was observed following low- and high-dose regimens for both per protocol (94% vs. 95%; P = N.S.) and intention-to-treat (93% vs. 94%; P = N.S.) analyses. No major side-effects were reported. Halving the clarithromycin dose leads to a per patient saving in pharmaceutical costs of 24.6 euros. None of the variables examined affected the effectiveness of eradication of the sequential regimen. CONCLUSION A reduction of the clarithromycin dose does not affect H. pylori eradication with the sequential regimen in non-ulcer dyspepsia and affords lower costs.

Abstract
Emollients play an important role in the management of atopic dermatitis (AD). The aim of this study was to evaluate the efficacy and the “steroid-sparing” activity of an emollient cream (Xanthena® cream) in patients with mild to moderate AD. Patients were asked to apply twice a day for 7 days a cream containing hydrocortisone butyrate on the lesionai skin and then to apply Xanthena® cream only on the left side of affected areas. During the 2-month study period, the use of the corticosteroid cream was resumed in case of flare-up in any side.The results obtained show significant differences of both the total severity score and the intensity of each symptom and sign of AD between the skin areas treated with Xanthena® cream and the control areas (P<0.05); a relevant reduction of steroid requirement was also noted in correlation with the use of this emollient cream (P<0.05). A significant improvement was observed even after the first month of therapy for most symptoms, except for excoriations/fissuring, oozing/crusting and burning which improved only at 2 months. Treatment was well-tolerated by the majority of patients; adverse local reactions, mostly transient and of mild intensity, were observed in 7% of cases.

Abstract
BACKGROUND/AIMS Alpha-interferon (alpha-IFN) and lamivudine are the two licensed drugs for patients with chronic hepatitis B, however, their efficacy in precore mutant chronic hepatitis B is limited. The aim of this study was to investigate the efficacy of 1 year alpha-IFN-lamivudine combination therapy for anti-HBe/hepatitis B virus- (HBV)-DNA positive patients. METHODS Between 1997 and 1999, 29 consecutive anti-HBe/HBV-DNA positive patients entered this prospective pilot study. Patients received 100mg lamivudine orally daily and alpha-IFN 6 million units (MU) three times weekly for 52 weeks. All patients were followed-up for 12 months after stopping therapy. Primary end points were loss of serum HBV-DNA and alanine transaminase normalization at week 52. RESULTS Overall, the end-treatment biochemical and virological response was 93% while the sustained response at week 104 was 14%. HBV-DNA negative patients did not experience a viral breakthrough during treatment; no tyrosine-methionine-aspartate-aspartate amino acid motif of HBV polymerase (YMDD) variant emerged. At week 52, 46% of patients with paired liver biopsies slides available, showed an histological improvement (histological activity index > or =2). CONCLUSIONS Combination of lamivudine and interferon for 1 year is followed by high end-treatment virological and biochemical response rates, by improvement of liver histology and by the prevention of the emergence of YMDD mutation; however, the sustained response rate remains low.

Abstract
We describe the cases of two patients with Crohn's disease affected by severe perineal fistulae resistant to conventional therapies, successfully treated with FK 506, a new immunomodulatory drug. It is well absorbed from diseased bowel and preliminary experiences have indicated its short-term use in complicated Crohn's disease. The first patient was a 24-year-old male with perineal fistula and severe skin ulceration (8 cm of external opening diameter). He had undergone colectomy and ileostomy because of severe pancolitis refractory to medical treatment and had been treated with azathioprine and metronidazole. Two months after starting FK 506, a dramatic improvement made further surgical operation unnecessary. Local and general benefit was observed during the following 26 months, until FK 506 was withdrawn. The second patient was a 28-year-old male with a diagnosis of ulcerative pancolitis changed to Crohn's disease two months after the onset of a perineal fistula, recurring despite drainage procedures, steroid therapy, and total parenteral nutrition. FK 506 was administered for two months with a complete healing of fistula. Successively, it was stopped and corticosteroids (associated to enteral nutrition) were given because of recurrent rectal bleeding. Our experience encourages the use of oral FK 506 in complicated Crohn's disease and suggests the possibility of a long-term primary therapy other than the use as a "bridge" to other treatments.

Abstract
Several clustered slow earthquakes have been recorded by a geodetic interferometer in central Italy. The strain rise times of the events range from tens to thousands of seconds, and the seismic moment scales with the square root of the rise time. This scaling law contrasts with the conservative assumption of constant rupture velocity in fault modeling but is consistent with the occurrence of a slow rupture propagation analogous to heat diffusion in a slab.

Abstract
BACKGROUND This is a report of the results of a multicenter study performed in children with dyspepsia from five pediatric centers in Puglia, a region in southern Italy. In the study, clinical features of Helicobacter pylori infection, the reliability of diagnostic techniques, and the involvement of bacterial strains were examined. METHODS Fifty-three outpatients with dyspepsia enrolled in our study and compiled a diary recording clinical symptoms in patients before they underwent the following diagnostic techniques: endoscopy, biopsy for histologic analysis, rapid urease test, 13C urea breath test, serology specific for immunoglobulin (Ig)G and anti-CagA and VacA. RESULTS H. pylori showed a prevalence of 30.2% (n = 16). Histologic positivity was seen in all patients at the antral level (H. pylori-associated chronic gastritis). In the gastric body, bacterial chronic active gastritis was present only in six patients (H. pylori-associated chronic pangastritis). Clinical evaluation showed a significant difference in favor of subjects positive for H. pylori only for epigastric burning and/or pain (p < 0.001). The comparison of results of diagnostic tests, using histology as the gold standard, showed sensitivity and specificity of more than 93% for 13C urea breath test and more than 85% for rapid urease test and serology. Anti-CagA antibodies were found in 64.3% and anti-VacA antibodies in 42.8% of H. pylori-positive patients. CONCLUSIONS H. pylori prevalence in children with dyspepsia from the geographic area studied is comparable with that found in other developed countries. Approximately 50% of the studied patients were infected by cytotoxic strains. The urea breath test was the most reliable noninvasive diagnostic tool and is suitable for routine use, although endoscopy with histologic assessment remains the definitive investigation and is particularly important in patients with positive serology for CagA and VacA. Finally, the frequency of aggressive strains in our region seems to affect the clinical pattern; this emphasizes the importance of definitive diagnosis in children and offers a new role for serology.

Abstract
INTRODUCTION Autonomic neuropathy is thought to play a role in the pathogenesis of slow-transit constipation, but other gastrointestinal organs may also be involved, even if they are symptom-free. We investigated whether motility in gastrointestinal organs other than the colon was impaired in patients with slow-transit constipation and whether the autonomic nervous system was involved. METHODS Twenty-one consecutive patients (18 females; median age, 46 years) with severe chronic constipation (< or = 2 defecations/week and delayed colonic transit time) were studied. Autonomic neuropathy function was tested with esophageal manometry, gastric and gallbladder emptying (fasting and postprandial motility) by ultrasonography, orocecal transit time (H2-breath test), colonic transit time (radiopaque markers), and anorectal volumetric manometry. The integrity of the autonomic nervous system was assessed by a quantitative sweat-spot test for preganglionic and postganglionic fibers, tilt-table test, and Valsalva electrocardiogram R-R ratio. RESULTS Esophageal manometry showed gastroesophageal reflux or absence of peristalsis in five of the seven patients examined. Gallbladder dysmotility (i.e., increased fasting, postprandial residual volume, or both) was observed in 6 of 14 (43 percent) patients. Gastric emptying was decreased in 13 of 17 (76 percent) patients. Orocecal transit time was delayed in 18 of 20 (90 percent) patients; median transit time was 160 (range, 90-200) minutes. Median colonic transit time was 97 (range, 64-140) hours. Anorectal function showed abnormal rectoanal inhibitory reflex and decreased rectal sensitivity in 11 of 19 (58 percent) patients. Signs of autonomic neuropathy of the sympathetic cholinergic system were found in 14 of 18 (78 percent) patients. Only one of nine patients had vagal abnormalities detected with the Valsalva test and four of five patients with a history of orthostatic hypotension had a positive tilt-table test. CONCLUSIONS Slow-transit constipation may be associated with impaired function of other gastrointestinal organs. More than 70 percent of patients with slow-transit constipation present some degree of autonomic neuropathy. Severe constipation may be the main complaint in patients with a systemic disease involving several organs and possibly involving the autonomic nervous system. This should be considered in the management of such cases.

Abstract
With the aim of investigating a possible relationship between "objective" halitosis (established by sulfide levels in the breath) and Helicobacter pylori, we performed a study in 58 dyspeptic patients reported to suffer from "bad breath." Furthermore, we evaluated the effects on halitosis of eradication therapy (only for H. pylori-positive patients) and chlorhexidine antiseptic mouth rinses (in all patients). Sulfide compound assay indicated objective halitosis in 52/58 patients, 30 of whom were positive and 22 negative for H. pylori. In 19/30 eradication by double therapy provoked a decrease to below the cutoff value of sulfide levels in 15. In the other 11 of the 30 subjects, in whom H. pylori positivity persisted, halitosis parameters did not change. Chlorexidine reduced sulfides to below the cutoff value in 16/22 H. pylori-negative patients, but did not provoke any change in the 11 unsuccessfully treated H. pylori-positive subjects. In these, objective halitosis disappeared only after a successful eradication by triple therapy (9/11). Our results show a possible association between halitosis and H. pylori since bacterial eradication may resolve the symptom. Antiseptic mouthwashes may be effective only in absence of H. pylori, when halitosis may be due to oral putrefactive microbial activity. In a small number of subjects the cause and treatment of halitosis need to be clarified.

Abstract
BACKGROUND Impaired changes in gastric epithelium proliferation have been described in Helicobacter pylori infection, and a progressive increase of proliferating cells has been shown with the progression of mucosal lesions. AIMS Purpose of this investigation was to study the effect of eradication on bacterium-induced proliferative changes, evaluated by the proliferating cell nuclear antigen labelling index (PCNA LI) and its relationship to the ras oncoprotein p21, involved in early events of gastric carcinogenesis. PATIENTS AND METHODS This retrospective study was performed, before and after therapy, in five different groups of patients with progressive stages of Helicobacter pylori damage (N: normality; HG: histological gastritis with normal endoscopy; EHG: histological gastritis with endoscopic chronic erosions; CIM: complete intestinal metaplasia; IIM: incomplete intestinal metaplasia). RESULTS Six months after eradication, a normalization of PCNA LI was observed in the areas of gastritis, but not in those of intestinal metaplasia, which showed on unchanged type. Moreover, immunohistochemical membrane expression of ras oncoprotein p21 was only associated to intestinal metaplasia. The protein was also expressed in the cytoplasm in 3 patients with incomplete type. CONCLUSIONS These results suggest that the development of intestinal metaplasia may be associated with an alteration in the control of gastric epithelium proliferation and could represent an initial stage in gastric carcinogenesis. Nevertheless, further genetic changes are necessary for a complete progression to neoplastic disease. A long-term follow-up on extension, type, proliferative situation and oncoprotein expression in areas of intestinal metaplasia may be helpful to explain whether the present data provide new information on the mechanism of Helicobacter pylori induced gastric carcinogenesis.

Abstract
Helicobacter pylori (HP) infection is the main etiopathogenetic agent responsible for inflammatory and ulcerative changes in gastroduodenal mucosa and the basis for both intestinal and diffuse types of gastric carcinoma. In this latter case, intestinal metaplasia is the intermediary between gastritis and cancer. In this study we describe the proliferative activity of gastric epithelium in the progressive stages of HP infection. The expression of proliferating cell nuclear antigen (PCNA), which has proven to be a reliable method for this evaluation, was used as a marker. The study was performed on endoscopic biopsies of the gastric antrum of 40 patients, who were divided into five groups, eight in each group: normal histology and endoscopy, HP-; histological HP+ gastritis with normal endoscopy; histological HP+ gastritis with endoscopic evidence of chronic erosions; complete and incomplete intestinal metaplasia in a HP+ stomach. PCNA was detected by immunohistochemistry and expressed as labeling index, ie, percentage of positive nuclei either in the whole or upper third of foveolae. Our data show a progressive increase of epithelial proliferation in the successive stages of HP infection ranging from gastritis alone to the development of incomplete intestinal metaplasia, a well-known precancerous condition. The proliferative pattern tended to expand towards the upper foveolar third, which in normal conditions does not represent a site of epithelial renewal. These alterations may be related to the development of neoplastic transformations of gastric epithelium. It is well known that genetic mutations are facilitated in proliferating cells. Therefore, our results indicate that the high epithelial turnover, expressed by PCNA LI, may be an indicator of increased risk of neoplastic changes in long-standing untreated HP+ chronic gastritis.

Abstract
In the last six years, 544 consecutive patients with nonsmall-cell bronchogenic carcinoma were studied with MRI. MR results were compared with surgical specimens and pathologic findings. Both TNM classification and ATS nodal mapping were considered. Local tumor extent (T parameter) was correctly identified in 67.2% of cases, understaged in 19.4% and overstaged in 13.4%. Lymph node metastases (N parameter) were adequately assessed in 55.5% of cases, understaged in 20.3% and overstaged in 24.2%. Considering two groups of patients, the first one with early stage disease (T1-T2, N0-N1) and the second one with advanced stages (T3-T4, N2-N3), MRI exhibited 84.6% overall accuracy, 57.3% sensitivity and 93.7% specificity for the T parameter and 72.3% accuracy, 65.2% sensitivity and 75.1% specificity for the N parameter. In conclusion, MRI did not provide the expected results in the staging of nonsmall-cell bronchogenic carcinoma, but improvement will probably be achieved with technological evolution.

The authors describe the experience gained during the four-year period 1988-1991 regarding the treatment of the pancreatic stump after DCP independently of the base pathology. The techniques used and conceptual evolution which led us to leave the pancreatic anastomosis are shown here; likewise the morbid physiology induced by this technique with all this variation is here tested. The positive results obtained support the method and encourage further developments.

Abstract
The goals of radiologic imaging in the study of tumors can be summarized as follows: 1) Definition of the exact volume and site of the lesion; 2) Tumor differentiation from surrounding structures; 3) Possible definition of tumor nature; 4) Follow-up. The radiologic imaging modalities to be considered are: a) conventional radiography; b) angiography; c) US; d) CT; e) MR. Of the above techniques, MR imaging can be considered as adequate to differentiate benign from malignant masses. Moreover, MR provides detailed information on both lesion and surrounding structure and allows histopathologic diagnosis. Finally, it is superior to CT with i.v. contrast medium in recognizing small lesions. Thus, dynamic MR imaging with paramagnetic contrast medium is currently considered the method of choice in evaluating recurrences and differentiating the latter from recent fibroses. MR limitations include the small number of units, their complexity and cost and exam duration.

Abstract
Estrogen (E) and epidermal growth factors (EGF) receptors were assayed in the liver of nine patients with hepatocellular carcinoma (HCC). Total E and nuclear E receptors were decreased significantly in neoplastic tissue as compared to the levels found in surrounding nonneoplastic tissue. The EGF receptor was decreased also in neoplastic tissue. On the basis of binding data, a decrease in the number but not in affinity of both the E and EGF receptors was found.

Abstract
Recently reports have indicated that both cimetidine and ranitidine delay cell proliferation in rats following 70% partial hepatectomy and result in an increased mortality following this procedure. The present study was designed to determine whether three H2 blocking agents (cimetidine, ranitidine, famotidine) and a new, powerful antisecretory drug (omeprazole) specifically influence hepatocyte proliferation in primary culture. Hepatocytes were isolated from livers of normal male rats by the standard collagenase perfusion technique. Hepatic DNA synthesis and percent of labelled nuclei were determined after 48 h incubation. Hepatocytes in culture were incubated with the H2 blocking agents and omeprazole or with different concentrations of serum obtained from sham-operated or 70% hepatectomized rats treated or not with the same agents. Rats were injected intraperitoneally at 8:00 a.m. on two consecutive days. In hepatectomized rats, the first dose was injected at 8:00 a.m. immediately after surgery, the second, 24 h later. The serum of sham-operated or 70% hepatectomized rats that did not receive drugs served as control. No changes in DNA synthesis, percentage of labelled nuclei and transaminase were detected when the agents were added to the hepatocytes in culture at concentrations within the effective pharmacological dosage and 30 times higher. Similarly, no changes in these parameters were obtained when different concentrations of serum obtained from sham-operated rats treated with H2 blocking agents or omeprazole were added to the basal culture medium. However, a significant inhibition of DNA synthesis and of percentage of labelled nuclei was observed when hepatocytes were incubated in the presence of serum from 70% hepatectomized rats that had been treated with cimetidine or with ranitidine. The serum of 70% hepatectomized rats treated with famotidine and omeprazole had no effect on hepatocyte proliferation in vitro. No effect on transaminase was found in these conditions.

Abstract
The intraseptal administration of the neurotoxin kainic acid (KA) induced a significant depletion of the neuronal population and glial proliferation in medial septal areas. The behavioral effects induced by this selective destruction of the neurons indigenous to the medial septal areas were investigated. KA produced a marked increase in urine output and a transient reduction in body weight, but failed to affect water and food intake.

Abstract
Cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) were assayed in ascitic fluid from 27 patients with ovarian carcinoma and 23 patients with liver cirrhosis. The value of these cyclic nucleotides was correlated with standard methods for the clinical evaluation of tumors. No change in the cGMP levels was found in either of these groups. The cAMP content, however, was increased in 23 of the 27 cases of ovarian carcinoma. The high cAMP level was correlated with the cytological findings in only 13 (48.1%) of these cases.

Abstract
The effect of glucagon on fasting gastrin levels was studied in normal subjects and in patients with advanced liver cirrhosis. Intravenous glucagon was given e.v. at a dose of 200 ng/kg/h and produced a significant decrease of serum gastrin levels at 50 min in controls while in cirrhotic patients there was no significant decrease. (p less than 0,01) Gastrin inhibition in normal subjects during glucagon infusion was significantly correlated to a simultaneous increase found in plasma cAMP and glucose levels. These findings suggest that hypergastrinemia in cirrhosis could be consequence of the failure of glucagon metabolic interactions.
