Improvement of quality of life in adolescents with epilepsy after an empowerment and sailing experience.

PURPOSE: Epilepsy in adolescents affects their psychological health, independence, and emotional adjustment. Psychological and self-management interventions might give benefits to adolescent with epilepsy in terms of quality of life, emotional well-being, and reduced fatigue. "Fondazione Tender To Nave Italia" promotes a project using sailing activities as an empowerment opportunity. The main aim of our study was to examine the empowerment effects on quality of life of adolescents with epilepsy attending sailing activities, and to compare the results perceived by adolescents and their parents. METHODS: Fifty-eight patients with a diagnosis of epilepsy were included in an empowerment project titled "Waves rather than spikes" from June 2013 to July 2018. Intellectual level was based on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria. Patients were administered Pediatric Quality of Life Inventory (PedsQL), adolescent and parent version. Behavioral data were collected by parent-report Child Behavior Checklist (CBCL). RESULTS: Thirty female and 28 male patients with a mean age of 15 years, referred to "Bambino Gesù Children's Hospital" in Italy, were included. Thirty-three (56.9%) patients had a history of refractory epilepsy; 34 (56.2%) received polytherapy, 19 (32.7%) monotherapy, and 5 (8.6%) were not taking antiepileptic drugs. Intellectual functioning was normal in 43 (74.1%), borderline in 9 (15.5%), and mildly impaired in 6 (10.3%). Results from PedsQL adolescent report revealed significant postintervention improvement for total score (p = 0.023) and in two domains: physical health (p = 0.0066) and emotional functioning (p = 0.015). Results from PedsQL parent report showed significant postintervention improvement for the domain of school functioning (p = 0.023). In the multivariate model, a low CBCL value was predicting a higher score in the health subscore difference between pre- and postempowerment activity (p = 000.8). CONCLUSION: Empowerments activities are crucial in order to reduce the burden of epilepsy in adolescents, and to improve quality of life. These are critical factors for a well-managed transition phase to adulthood.

Effectiveness of Trichoderma strains isolated from the rhizosphere of citrus tree to control Alternaria alternata, Colletotrichum gloeosporioides and Penicillium digitatum A21 resistant to pyrimethanil in post-harvest oranges (Citrus sinensis L. (Osbeck)).

AIMS: Penicillium digitatum, Alternaria alternata and Colletotrichum gloeosporioides are pathogens responsible for large decays and production losses of citrus. They are commonly controlled by fungicides, whose excessive applications have led to the emergence of resistant P. digitatum strains. Alternative approaches are imperative for sustainable and environmental harmless citrus production, being biological control a promising strategy. The objective was to evaluate the potential of Trichoderma strains native from the rhizosphere of citrus trees to control these pathogens. METHODS AND RESULTS: Seven strains were isolated and identified as Trichoderma harzianum, T. guizhouense, T. atroviride and T. koningiopsis through morphological and molecular analyses. Five of them showed effective antagonist performance in vitro against the pathogens. The strain T. harzianum IC-30 was the best biological control agent in vivo, obtaining a reduction of rot percentage around 80% after 3 weeks of infection of oranges with P. digitatum A21 (resistant to pyrimethanil). This strain also showed the highest chitinase and glucanase activities. CONCLUSIONS: Trichoderma harzianum IC-30 is an optimal antagonist for the control of green mould spreading and other pathogens in post-harvest citrus fruits. SIGNIFICANCE AND IMPACT OF THE STUDY: The strain combined with supplementary practices could lead to sustainable management of citrus fungal diseases, dispensing with synthetic fungicides.

Abdominal adiposity is an early marker of pulmonary function impairment: Findings from a Mediterranean Italian female cohort.

BACKGROUND AND AIMS: Abdominal adiposity may influence the respiratory function, especially in women. The aim of this prospective study is to evaluate the predictive role of body mass index (BMI) and waist circumference (WC) on lung function in healthy women. METHODS AND RESULTS: In 600 women randomly selected from the cohort of the "Progetto ATENA," anthropometric measures such as BMI, WC, and weight gain were recorded at baseline, and the spirometric parameters were measured 10 years later. The percentage values of forced expiratory volume in 1 s (FEV1%) and forced vital capacity (FVC%) and the ratio of FEV1/FVC were compared with the anthropometric measures after adjustment for several variables measured at baseline such as age, height, socioeconomic status, smoking habits, and history of respiratory allergies grouped in a basal model. WC is significantly associated with a decreased FVC (p = 0.008) and an increased ratio of FEV1/FVC (p = 0.031) after adjustment for the covariates of the basal model. The association between BMI and spirometric parameters reaches borderline significance only with the ratio of FEV1/FVC (p = 0.052). CONCLUSIONS: We suggest measuring both BMI and WC to assess the risk of future respiratory impairment.

Risk of permanent stoma in extensive Crohn's colitis: the impact of biological drugs.

AIM: The overall risk of permanent stoma was determined in patients with extensive Crohn's colitis. An attempt was made to analyse whether biological drugs have modified the surgical approach in patients with anorectal involvement. METHOD: In all, 233 patients with Crohn's disease colitis operated on between 1995 and 2010 were reviewed retrospectively. Fifty-one were treated before 2002 (prebiological era) and 182 after 2002 (biological era). The relationship was determined between the use of immunosuppressors, biological drugs, the presence of perianal disease and anorectal stenosis and the rate of permanent stoma formation. RESULTS: In the prebiological era 23 (45.1%) patients without anorectal involvement underwent colectomy and ileorectal anastomosis, 17 (33.3%) with severe anorectal disease had proctocolectomy and 11 (21.6%) with anorectal involvement had abdominal colectomy with permanent ileostomy. In the biological era 73 (40.1%) patients without anorectal involvement underwent colectomy and ileorectal anastomosis, nine (5%) with severe anorectal involvement had proctocolectomy and 100 (54.9%) with anorectal involvement had colectomy with terminal ileostomy. Of these 100, 75 have subsequently been treated with biological drugs with full regression of anorectal lesions in 81.3%. Rates of permanent stoma in the prebiological and biological era were 60.8% and 19.2% (P < 0.001). Univariate and multivariate analysis showed that only the use of biological drugs was significantly associated with an increased rate of rectal preservation (P < 0.05). CONCLUSION: The risk of a permanent stoma in patients with Crohn's colitis and anorectal involvement is significantly reduced with combined surgical and biological treatment.

The Intersection of COVID-19 and Autoimmunity: What is Our Current Understanding?

Viral infections have historically had a complex relationship with autoimmune diseases. For patients with preexisting autoimmune disorders, often complicated by immunosuppressive therapies, there are numerous potential effects of COVID-19, a disease of complex immunobiology, including the potential for an altered natural history of COVID-19 when infected. In addition, individuals without recognized autoimmune disease may be vulnerable to virally induced autoimmunity in the forms of autoantibody formation, as well as the development of clinical immune-mediated inflammatory diseases. Until quite recently in the pandemic, this relationship between COVID-19 and autoimmune diseases has been relatively underexplored; yet such investigation offers potential insights into immunopathogenesis as well as for the development of new immune-based therapeutics. Our review examines this relationship through exploration of a series of questions with relevance to both immunopathogenic mechanisms as well as some clinical implications.

Predictive power of modified frailty index score for pulmonary complications after major abdominal surgery in the elderly: a single centre prospective cohort study.

OBJECTIVE: The primary aim of this prospective cohort study was to evaluate the usefulness of the modified Frailty Index (mFI) score to predict postoperative pulmonary complications (PPCs) in elderly patients undergoing major open abdominal surgery. The secondary purpose was to compare the prediction power of mFI, Ariscat (Assess Respiratory Risk in Surgical Patients in Catalonia), and American Society physical status classification (ASA) scores. PATIENTS AND METHODS: After local Ethical Committee approval, 105 patients aged ≥65 years undergoing open major abdominal surgery were enrolled. Clinical data were compared between patients with or without PPCs (including respiratory failure, aspiration pneumonia, pulmonary infection, pleural effusion, pneumothorax, atelectasis, bronchospasm or un-planned re-intubation). t-test or χ2-test were performed for univariate analyses. Logistic regression analysis was used to identify independent predictors of PPCs. Non parametric ROC (Receiver Operating Characteristic) was used for cut-off calculation. AUCs (areas under ROC curve) of preoperative scores were compared using χ2-test. RESULTS: PPCs prevalence (11.3%) was associated with increased mFI, ASA, and Ariscat scores, greater age, hemoglobin levels <10 g/dl, peripheral oxygen saturation <95% (p=0.0001) and longer surgery duration. Logistic regression showed that mFI (p=0.0001) and Ariscat (p=0.04) were independent predictors of PPCs. The predictive power of mFI (AUC=0.90) was similar to that of Ariscat (AUC=0.81) (χ2=2.53; p=0.11) but greater than that of ASA (AUC=0.69) (χ2=9.85; p=0.002). An mFI≥0.18 was predictive of PPCs (sensitivity=90.91%; specificity=79.07%). An Ariscat score of 27 was the cut-off identified as determining factor for PPCs occurrence (sensitivity=90.91%; specificity=51.16%). CONCLUSIONS: Elderly patients with an mFI ≥0.18 and/or an Ariscat score ≥27 were at higher risk of PPCs after open major abdominal surgery. More attention should be paid to these patients by implementing both strict monitoring and strategies for PPCs prevention in the perioperative period.

T cell activation state in the induced sputum of asthmatics treated with budesonide.

Bronchial hyperresponsiveness and airway infiltration with eosinophils and T lymphocytes are key features of asthma. In particular, CD4+ T cells are currently believed to play a pivotal role as initiators and coordinators of the asthmatic inflammatory response and, therefore, they represent a crucial target of corticosteroid treatment. The aim of the present investigation is thus to evaluate, in patients with mild asthma, the effects of inhaled corticosteroid therapy on the following parameters: (i) functional state of CD4+ T cells; (ii) airway eosinophilia; (iii) bronchial hyperresponsiveness to methacholine. The study was completed by twenty asthmatic, atopic subjects, subdivided into two groups of ten and treated for 12 weeks with either inhaled budesonide (200 microg twice daily) or terbutaline alone (500 microg twice daily), respectively. Expression of CD4+ T cell activation markers was measured in induced sputum at baseline and after 1, 4, 8 and 12 weeks of treatment by flow cytometry, which showed a down-regulation of HLA-DR and CD25 surface proteins in the budesonide group, compared with the control group; these differences resulted as being statistically significant through weeks 4-12. Budesonide also induced a quick, sharp reduction in the percentage of eosinophils detectable in induced sputum, as well as a more gradual progressive improvement in airway hyperresponsiveness to methacholine. Therefore, in addition to assessing various indices of bronchial inflammation, flow cytometry can be reliably applied to induced sputum in order to monitor, even in mildly symptomatic patients, the effects of anti-asthma treatments on T cell activation.

Neuropeptide expression in the airways of COPD patients and smokers with normal lung function.

Neurogenic mechanisms seem to play a role in the pathogenesis of chronic obstructive pulmonary disease (COPD), as suggested by a number of in vitro data. However, few studies have investigated the presence of neuropeptides in the airways of patients with COPD, and they have yielded conflicting results. The aim of this study is to compare the expression of the neuropeptide substance P (SP), vasoactive intestinal peptide (VIP), and neuropeptide Y (NPY) in the airways of smokers with and without COPD. Surgical lung samples were obtained from 15 smokers with COPD and 16 smokers with normal lung function, who underwent lobectomy for a solitary lung carcinoma. Airway expression and distribution of SP, VIP, and NPY were identified by immunohistochemistry and analyzed by a computerized image analysis system. Compared to smokers with normal lung function, COPD patients exhibited an increased immunoreactivity for SP and VIP, paralleled by a decreased NPY expression in the epithelium and glands, and a decreased expression of all these three neuropeptides in the smooth muscle layer. Therefore, in the present study we have documented a different expression and distribution of the neuropeptides SP, VIP, and NPY in the airways of smokers with and without COPD. These findings suggest a possible involvement of such neuropeptides in the pathogenesis of some changes occurring in COPD.

A comparison of airway interventions and gastrostomy tube placement in infants with Robin sequence.

The purpose of this study was to evaluate feeding impairment following non-operative or operative management of airway obstruction in a large series of infants with Robin sequence (RS) by rate of G-tube placement. A retrospective study was conducted at Boston Children's Hospital including 225 patients (47.1% female) with RS treated between 1976 and 2018. Subjects were grouped by intervention required for successful management of airway obstruction: non-operative only (n = 120), tongue-lip adhesion (TLA, n = 75), mandibular distraction osteogenesis (MDO, n = 21), or tracheostomy (n = 9). The operative group had a higher rate of G-tube placement (58.1%) than the non-operative group (28.3%, P < 0.0001). Subjects in the TLA and tracheostomy groups had higher odds of G-tube placement than subjects in the MDO group: odds ratio (OR) 5.5 (95% confidence interval (CI) 1.8-17.3, P = 0.004) and OR 27.0 (95% CI 3.2-293.4, P = 0.007), respectively. Syndromic patients and those with gastrointestinal anomalies also had higher odds of G-tube placement: OR 3.5 (95% CI 1.7-7.2, P = 0.001) and OR 5.9 (95% CI 1.6-21.0, P = 0.007), respectively. Infants with RS who require an airway operation and those with a syndromic diagnosis or gastrointestinal anomalies are more likely to require placement of a G-tube. Of the operative groups, MDO was associated with the lowest G-tube rate, compared to TLA and tracheostomy.

Conformational impact of aliphatic side chains in local anaesthetics: benzocaine, butamben and isobutamben.

We studied the impact of aliphatic side chains on the stability and conformational landscape of the local anaesthetics benzocaine, butamben and isobutamben, combining high-resolution rotational spectroscopy in the microwave and millimetre regions and molecular modelling. The study reveals the connections between alkyl chain flexibility and molecular conformations.

Subcutaneous expanders and synthetic mesh for breast reconstruction: Long-term and patient-reported BREAST-Q outcomes of a single-center prospective study.

Recently, prepectoral breast reconstruction is experiencing a revival. Despite the growing body of early reports about subcutaneous breast reconstruction, literature lacks in long-term results and studies focusing on patient-reported outcomes and health-related quality of life. Between January 2012 and December 2016, patients undergoing mastectomy were enrolled at our institution. We selected patients diagnosed with breast cancer or genetic predisposition to breast cancer, undergoing conservative mastectomy, either nipple-sparing or skin-sparing mastectomy, and willing for prepectoral tissue expander reconstruction assisted by a synthetic mesh. Exclusion criteria were body mass index greater than 35 kg/m2 and pregnancy. BREAST-Q questionnaire was administered prior to surgery and after 1 year. Capsular contracture was evaluated using Baker scale. Oncological, surgical, and esthetic outcomes along with the changes in BREAST-Q score were analyzed over time. One hundred eighty-seven patients were enrolled, with an average age of 55.5 years. One hundred thirty-seven unilateral mastectomy and 50 bilateral mastectomy procedures were performed, accounting for a total of 237 operated breasts. The average follow-up period after the second stage was 36.5 months. Postoperative complications that require a second operation occurred in 16 cases (6.7%) (4 wound dehiscence, 2 skin-nipple necrosis, 7 infections, and 3 seroma cases). A locoregional recurrence occurred in 3 cases (1.9%) and a systemic recurrence occurred in 2 cases (1.3%). Patients scored high level of satisfaction with outcome. Overall satisfaction with breasts, psychosocial well-being, and sexual well-being was all significantly increased after the surgery (p < 0.05). Two-stage expander reconstruction technique provides the preservation of the pectoralis major muscle with an acceptable rate of complications. We confirm satisfactory patient-reported and esthetic results, with high patient comfort.

Oncoplastic conservative surgery for breast cancer: long-term outcomes of our first ten years experience.

OBJECTIVE: The main goal of oncoplastic breast surgery (OBS) is to optimize cosmetic outcomes and reduce patient morbidity, while still providing an oncologically-safe surgical outcome and extending the target population of conservative surgery. Although the growing number of reported experiences with oncoplastic surgery, few studies account for the long-term outcomes. PATIENTS AND METHODS: Between January 2000 and December 2010, 1024 consecutive oncoplastic surgeries were performed and prospectively included in a database. Demographic data, histological and oncological evaluation and surgical complications were recorded. The role of tumor and patients' characteristics on the development of local recurrence and metastases were assessed by multivariate analysis. RESULTS: Median follow up was 74.2 months. The average age of patients was 56.24. In 869 patients (84.9%) an invasive tumor and in 155 (15.1%) an in situ tumor (11% DCIS and 4% LIN) was found. The average size of the tumor was 24.5 mm. A positive margin presented in 67 (6.5%) patients. Forty patients (50%) underwent re-excision and 39 (49.4%) underwent mastectomy. The overall breast conservation rate was 96.2%. Reported complications were: 17 wound infections (1.7%); 106 hematomas (10.4%); 94 lymphorrheas (9.2%), 48 partial wound dehiscence (4.7%). Local recurrences (LR) were observed in 49 patients (4.7%). The risk of local recurrence was significantly higher in the group of patients with lymphovascular invasion and with high grade (G) (p < 0.05). 52 (5.07%) distant metastases were reported and the related risk was significantly higher in the group of patients with lymphovascular invasion and with negative receptors (p < 0.05). CONCLUSIONS: Oncoplastic surgery provides an acceptable oncological long-term outcome and can be used to treat with conservative surgery also a selected population of patients who would had otherwise undergone mastectomy in the past.

Nipple-sparing bilateral prophylactic mastectomy and immediate reconstruction with TiLoop® Bra mesh in BRCA1/2 mutation carriers: A prospective study of long-term and patient reported outcomes using the BREAST-Q.

BACKGROUND: Although demand for prophylactic mastectomy is increasing over time among women at a high risk for breast cancer, there is a paucity of studies on long term patient-reported outcomes after this procedure. METHODS: Between January 2011 and January 2015, 46 patients documented BRCA1/2 mutation carriers, eligible for prophylactic nipple-sparing mastectomy (NSM) and immediate breast prosthetic reconstruction were registered at our Institution. Patients underwent NSM and subcutaneous reconstruction with implant covered by a titanium-coated polypropylene mesh (TiLoop®). The BREAST-Q questionnaire was given to patients prior to surgery and at 1 and 2 years follow-up points. Capsular contracture was evaluated by Baker scale. Surgical outcomes along with the changes in BREAST-Q score were analyzed over time. RESULTS: Complications were reported in only one case and after two years the capsular contracture rates were acceptable (grade I: 65,2%; grade II: 32,6%; grade III 2,2%). At one year and two year follow-ups patients reported high rates in the measures of overall satisfaction with breasts (72,5 and 73,7 respectively), psychosocial well-being (78,4 and 78,6), sexual well-being (58,8 and 59,4), physical well-being (77,6 and 80,6) and overall satisfaction with outcome (75,7 and 79,7). A statistically significant increase in all BREAST-domains from the preoperative to the postoperative period was reported at one and two years follow-ups (p < 0,05). CONCLUSION: Following bilateral prophylactic NSM and immediate subcutaneous reconstruction with TiLoop®, patients demonstrated high levels of satisfaction and quality of life as measured by BREAST-Q. 2-years outcomes confirmed high patient comfort with increased scores from the preoperative baseline level.

Meta-analyses on intra-aortic balloon pump in cardiogenic shock complicating acute myocardial infarction may provide biased results.

OBJECTIVE: Intra-aortic balloon pump (IABP) is the device most commonly investigated in patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI). Recently meta-analyses on this topic showed opposite results: some complied with the actual guideline recommendations, while others did not, due to the presence of bias. We investigated the reasons for the discrepancy among meta-analyses and strategies employed to avoid the potential source of bias. MATERIALS AND METHODS: Scientific databases were searched for meta-analyses of IABP support in AMI complicated by CS. The presence of clinical diversity, methodological diversity and statistical heterogeneity were analyzed. When we found clinical or methodological diversity, we reanalyzed the data by comparing the patients selected for homogeneous groups. When the fixed effect model was employed despite the presence of statistical heterogeneity, the meta-analysis was repeated adopting the random effect model, with the same estimator used in the original meta-analysis. RESULTS: Twelve meta-analysis were selected. Six meta-analyses of randomized controlled trials (RCTs) were inconclusive because underpowered to detect the IABP effect. Five included RCTs and observational studies (Obs) and one only Obs. Some meta-analyses on RCTs and Obs had biased results due to presence of clinical and/or methodological diversity. The reanalysis of data reallocated for homogeneous groups was no more in contrast with guidelines recommendations. CONCLUSIONS: Meta-analyses performed without controlling for clinical and/or methodological diversity, represent a confounding message against a good clinical practice. The reanalysis of data demonstrates the validity of the current guidelines recommendations in addressing clinical decision making in providing IABP support in AMI complicated by CS.

Oncological safety of stromal vascular fraction enriched fat grafting in two-stage breast reconstruction after nipple sparing mastectomy: long-term results of a prospective study.

OBJECTIVE: Autologous fat transfer (AFT) is commonly used to treat implant palpability and prevent fibrosis and thinning in mastectomy skin flaps. A major limit to this procedure is volume retention over time, leading to the introduction of fat enrichment with stromal vascular fraction (SVF+AFT). Oncological concerns have been raised over the injection of an increased concentration of progenitors cells (ASCs) in the SVF. The aim of the study is to evaluate the long-term cancer recurrence risk of SVF+AFT cases compared to AFT, in patients undergoing Nipple Sparing Mastectomy (NSM). PATIENTS AND METHODS: A prospective study was designed to compare three groups of patients undergoing NSM followed by SVF+AFT, AFT or none (control group), after a two-stage breast reconstruction. Patients were strictly followed-up for at least 5-years from the second stage reconstructive procedure. Loco-regional and systemic recurrence rate were evaluated over time as the primary outcome. Logistic regression was used to investigate which factors were associated with recurrence events and independent variables of interest were: surgical technique, age above 50 years old, lympho-vascular invasion, oncological stage, adjuvant or neoadjuvant chemotherapy, adjuvant radiotherapy and adjuvant hormone therapy. RESULTS: 41 women were included in G1 (SVF+AFT), 64 in G2 (AFT), and 64 in G3 (control group). Loco-regional recurrence rate was 2.4% for G1, 4.7% for G2, and 1.6% for G3. Systemic recurrence was 7.3%, 3.1%, and 3.1%, respectively. Among the variables included, there were no significant risk factors influencing a recurrence event, either loco-regional or systemic. In particular, SVF+AFT (G1) did not increase the oncological recurrence. CONCLUSIONS: Our data suggest that both centrifuged and SVF-enhanced fat transfer have a similar safety level in comparison to patients who did not undergo fat grafting in breast reconstruction after NSM.

Oral budesonide in the treatment of chronic refractory pouchitis.

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.

Controlled study using wireless capsule endoscopy for the evaluation of the small intestine in chronic refractory pouchitis.

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.

Endoscopic appearance of GERD: putative role of cell proliferation.

BACKGROUND: Erosive esophagitis is a frequent endoscopic feature in patients with gastro-oesophageal reflux disease. However, most of patients with heartburn/regurgitation have a non-erosive reflux disease. The reason for this heterogeneous impact of gastro-oesophageal reflux disease on oesophageal mucosa is unknown to date. AIM: To evaluate the cell proliferation status of oesophageal epithelium in both healthy normal subjects and patients with gastro-oesophageal reflux disease with or without erosions. MATERIALS AND METHODS: All the subjects underwent endoscopy and biopsies were taken at 5 cm from the squamo-columnar junction. Specimens were analysed both at histology and at transmission electron microscopy. Cell proliferation was evaluated by MIB1 immunostaining. Of the 85 subjects were studied, 10 were healthy controls with normal pH-testing and macroscopical, histological and ultrastructural patterns; 37 were patients with erosive esophagitis, and 38 patients with non-erosive reflux disease. RESULTS: At histology, of the 37 patients affected by erosive esophagitis, 30 had normal mucosa and 7 showed mild oesophagitis. One patient with non-erosive reflux disease showed signs of oesophagitis at histology. At TEM, all patients with gastro-oesophageal reflux disease had ultrastructural patterns of damage i.e. dilations of intercellular spaces (DIS), and all controls had a normal ultrastructural pattern. The mean (+/-SD) MIB1-LI values of normal subjects and non-erosive reflux disease and erosive oesophagitis patients were 62.2% (+/-9.1), 29.7% (+/-7.2) and 16.2% (+/-5.2), respectively; there were significant differences among the three groups (p<0.001). CONCLUSIONS: Oesophageal mucosa of patients with reflux symptoms presents a decrease in MIB1 immunostaining of 50% and 25% in non-erosive reflux disease and erosive esophagitis patients with respect to normal subjects.

[Ticks bite in foresters]. / Punture di zecche in operai forestali.

The objective of the study is evalutation of the risk for ticks strings on foresters. The sample constituted by 325 foresters belong to Messina province as been submitted to medical examination venous tests. Whole sample had to answer to a questionnaire to consider. The prevalence of systemic and skin reactions and we have dose Immunoglobulines versus Brucella Melitensis, Rickettsie Conorii e Borrelia Burgdorferi. The results showed that the 19% has declared past stings of tick, and 4.9% reported symptoms probably deriving to a past infections determined by inquired microorganisms. The serum tests showed that 70% was positive for all microorganisms, instead only 31%. Was never infected by inquired microorganisms. In conclusion our study shows that zoonos is risk linked to stings of tick is relatively high in foresters.
