Abstract
AIM The effectiveness of rectal washout was compared with no washout for the prevention of local recurrence after anterior rectal resection for rectal cancer. METHOD The following electronic databases were searched: PubMed, OVID Medline, Cochrane Database of Systematic Reviews, EBM Reviews, CINAHL and EMBASE. RESULTS Five nonrandomized studies including a total of 5012 patients were identified. Meta-analysis suggested that rectal washout significantly reduced the local recurrence rate (P < 0.0001; OR 0.57; 95% CI 0.43-0.74). It was also significantly lower after washout in patients having radical resection only (P = 0.0004; OR 0.54; 95% CI 0.39-0.76), patients treated by a curative resection (P < 0.0001; OR 0.55; 95% CI 0.42-0.72) and those undergoing preoperative radiotherapy (P = 0.04; OR 0.62; 95% CI 0.39-0.98). CONCLUSION Taking into account the limitations of the design of the included studies the meta-analysis showed that rectal washout is associated with reduced local recurrence and therefore should be routine during anterior resection for rectal cancer.

Abstract
Ethylene glycol monoethyl ether or 2-ethoxyethanol finds a wide industrial application as a solvent for lacquers, inks, dyes, household products and as a surfactant. It is also found in cosmetics such as nail products, face cleansers, liquid soaps, oral care products, hair colours and fixatives. The potential hazard to human health of 2-ethoxyethanol following inhalation and dermal exposure has been recently reviewed and the European Cosmetic, Toiletry and Perfumery Association (COLIPA) has issued recommendations suggesting its non-use as a cosmetic ingredient. Therefore a simple and fast monitoring method is necessary for routine control to identify and quantify 2-ethoxyethanol in raw materials and finished cosmetics. We have developed a sensitive and selective method to determine 2-ethoxyethanol in complex matrices by precolumn derivatization with 1-naphthyl isocyanate and RP-HPLC analysis. Four laboratory-made cosmetic formulations (a nail lacquer remover, a baby oil, a skin lotion and an emollient O/W emulsion) containing three known amounts of 2-ethoxyethanol (0.1%, 2.0%, 5.0%) have been studied. The obtained results show that this chromatographic procedure provides a good estimate of the true concentration of 2-ethoxyethanol in complex matrices and it is reliable for routine analyses in quality control.

Abstract
AIM Loop ileostomy is a suitable procedure for transitory faecal diversion after low colorectal anastomosis, but it causes relevant morbidities (discomfort, peristomal infections, dehydration) and requires a second operation to be closed. We already described an alternative technique of temporary percutaneous ileostomy (TPI) that can be removed without surgery. METHOD The data of 143 consecutive patients, undergoing elective laparoscopic anterior resection of the rectum for adenocarcinoma and low mechanical colorectal anastomosis, 68 with conventional loop ileostomy (CLI) and 75 with TPI, were analyzed. RESULTS Neither intra-operative complications nor deaths occurred during the follow-up period. Clinical anastomotic leakage occurred in 4 patients with CLI and in 1 with TPI (p = 0.191). The median time required for the emission of gases and faeces through the stoma was respectively 1 and 2.5 days in the CLI group, and 1 and 2 days in the TPI group (p = 0.259 and p = 0.126). The median post-operative stay was 8 days in the CLI group and 11 days in the TPI group (p < 0.001). PTIs were removed on the median of 9 days after surgery without major complications, whereas the CLIs were re-canalized in 79.4% of patients on an average of 106 days, with 2 major complications. CONCLUSION The temporary percutaneous ileostomy seems to be a valid alternative to conventional ileostomy, ensuring optimal faecal diversion and less patient discomfort. It can be easily removed without surgery, allowing patients a better outcome.

Abstract
AIM The aim of this systematic review was to compare laparoscopic and/or laparoscopic-assisted right colectomy (LRC) with open right colectomy (ORC). Many randomized clinical trial have shown that laparoscopic colectomy benefits patients with improved short-term outcomes and comparable overall survival in respect to the open approach. These results, however, could not be applied to right colectomy owing to its wide range of resection and more complicated vascular regional anatomy. METHOD We performed a meta-analysis of the literature in order to compare LRC vs ORC by examining 21 end-points including operative and recovery outcomes, early postoperative mortality and morbidity, and oncological parameters. A subgroup analysis of patients undergoing right colectomy for cancer was carried out. The meta-analysis was conducted following all aspects of the Cochrane Handbook for systematic reviews and Preferred Reporting Items for Systematic Reviews and Metanalysis (PRISMA) statement. The search strategies were developed using the following electronic databases: PubMed, EMBASE, OVID, Medline, Cochrane Database of Systematic Reviews, EBM reviews and CINAHL until March 2011. We included randomized and non randomized studies that compared the LRC vs ORC for benign disease and malignant neoplasm irrespective of publication status. Only studies in English, French, German, Spanish and Italian languages were considered for inclusion. Emergency right colectomies were excluded. To perform the statistical analysis we used the odds ratio (OR) for categorical variables and the weighted mean difference (WMD) for continuous variables. An intention-to-treat analysis was performed. RESULTS Seventeen studies, 15 nonrandomized clinical trials and two randomized clinical trials, involving a total of 1489 patients, were identified. The mean operative time was longer in the group of patients undergoing LRC [weighted mean difference (WMD) = 37.94, 95% CI: 25.01 to 50.88; P < 0.00001]. Intra-operative blood loss (WMD = -96.61; 95% CI: -150.68 to -42.54; P = 0.0005), length of hospital stay (WMD = -2.29; 95% CI: -3.96 to -0.63; P = 0.007) and short-term postoperative morbidity (OR = 0.64; 95% CI: 0.49 to 0.83; P = 0.0009) were significantly in favour of LRC. CONCLUSION Laparoscopic-assisted right colectomy results in less blood loss, a shorter length of hospital stay and lower postoperative short-term morbidity compared with ORC.

Abstract
BACKGROUND Apnoea of prematurity (AOP) frequently recurs in preterm infants. We have previously shown that a significant but variable proportion of AOP is induced by gastro-oesophageal reflux (GOR). AIM The aim of this study is to evaluate the efficacy of sodium alginate in reducing the frequency of GOR-related AOP. SUBJECTS Twenty-eight preterm infants with AOP were studied by a six-hour recording of combined multichannel intraluminal impedance and pH monitoring and polysomnography, including two three-hour postprandial periods: sodium alginate was given after one single meal named as drug-given (DG) meal, while the other as drug-free (DF). RESULTS During 165h of registration, 715 apnoeas were recorded, 368 after-DG and 347 after-DF (p=.99); furthermore, 851 GOR episodes were detected, 315 after-DG and 536 after-DF (p=.001). No differences in the number of AOP were found between DG and DF. A significant reduction in the number of acid GORs and in acid exposure was found during DG, while the administration of sodium alginate didn't influence non-acid GOR indexes. The frequency of GOR-related apnoeas didn't differ between DG and DF. DISCUSSION Sodium alginate doesn't reduce the total number of AOP nor GOR-related apnoeas. On the other hand, it reduces acid GOR features, while it had no effect on non-acid GOR indexes.

Abstract
BACKGROUND To evaluate whether physical and/or chemical features of gastro-esophageal reflux (GER) influence its relationship with apnea of prematurity (AOP). METHODS Fifty-eight preterm newborns (GA ≤ 33 weeks) with recurrent apneas were studied by simultaneous polysomnography and combined impedance and pH monitoring, to analyze whether the correlation between GER and AOP varies according to the acidity, duration and height of GERs. KEY RESULTS The frequency of apnea (number apnea/min) occurring after-GER [median (range) 0.07 (0-0.25)] was higher than the one detected in GER-free period [0.06 (0.04-0.13), P = 0.015], and also than the one detected before-GER [0 (0-0.8), P = 0.000]. The frequency of apneas detected in the 30'' after pH-GER [median (range), 0 min(-1) (0-1.09)] was higher than the frequency detected in the 30'' before [0 (0-0.91), P = 0.04]; even more, the frequency of apneas detected after non-acid MII-GER episodes [0 (0-2)] was significantly higher than the one detected before [0 (0-1), P = 0.000], whereas the frequency of apneas detected before acid MII-GER episodes [0 (0-0.67)] did not differ from the one detected after [0 (0-2), P = 0.137]. The frequency of pathological apneas detected in the 30'' after-GER (0 min(-1), range 0-0.55) was higher than the frequency detected before (0, range 0-0.09; P = 0.001). No difference in mean height or in mean duration was found between GERs correlated and those non-correlated to apnea. CONCLUSIONS & INFERENCES Non-acid GER is responsible for a variable amount of AOP detected after-GER: this novel finding must be taken into consideration when a therapeutic strategy for this common problem is planned.

Abstract
BACKGROUND Gastro-oesophageal reflux is common in preterm newborns; at present, no studies have evaluated the efficacy of sodium alginate in this population. AIM To evaluate the effect of sodium alginate on gastro-oesophageal reflux features in preterm newborns by combined pH and impedance monitoring (pH-MII). METHODS Thirty-two symptomatic preterm newborns underwent a 24 h pH-MII, during which each baby was fed eight times. Sodium alginate was given four times at alternate meals [drug-given (DG) vs. drug-free (DF) meals]. Gastro-oesophageal reflux features (i.e. number, acidity, duration and height of gastro-oesophageal reflux) after DG and DF meals were compared by Wilcoxon signed ranks test. RESULTS Sodium alginate significantly decreased the number of acid gastro-oesophageal reflux detected either by pH monitoring (DG vs. DF: median 17.00 vs. 29.00, P = 0.002) and MII (DG vs. DF: 4.0 vs. 6.00, P = 0.050), and also acid oesophageal exposure (DG vs. DF: 4.0% vs. 7.6%, P = 0.030), without any influence on non-acid gastro-oesophageal reflux. Furthermore, it decreased the number of gastro-oesophageal reflux reaching proximal oesophagus (DG vs. DF: 5.50 vs. 7.50, P = 0.030). CONCLUSIONS The use of sodium alginate in preterm infants seems to be promising, because this drug decreases gastro-oesophageal reflux acidity and height with the advantage of a nonsystemic way of action and a more favourable safety profile over H2 blockers and PPIs.

Abstract
AIM Loop ileostomy is a suitable procedure for transitory faecal diversion after colorectal or coloanal anastomosis. We describe here an easy alternative technique for ileostomy construction that does not require reintervention for the closure. METHOD In twenty patients undergoing anterior resection of the extraperitoneal rectum with colorectal and/or coloanal anastomosis, loop ileostomy was performed using a modified jejunotomy tube inflated with 10 ml of normal saline. The tube was deflated on the eighth post-operative day and removed on day 11 after a radiological contrast enema of the anastomosis. RESULTS Radiological control carried out on day 11 evidenced a premature dislocation of the jejunostomy tube in 1 patient, thus the tube was correctly removed without any complications. In another patient a delayed closure of the ileo cutaneous fistula was recorded that required simple medication over 15 days in the out patient clinic. No signs of anastomotic leakage, either clinical or radiological were evidenced. CONCLUSION We have described here a safe alternative technique for loop ileostomy with negligible complications related to construction as demonstrated in our results.

Abstract
The tyrosine kinase receptor RET51 is expressed in distinct families of neurons where it promotes different functions. FKBP52 is an immunophilin with neuroprotective effects on different kinds of neurons. In this paper, we demonstrate that RET51 activation by both glial cell line-derived neurotrophic factor (GDNF) and NGF triggers the formation of RET51/FKBP52 complex. The substitution of the tyrosine 905 of RET51, a key residue phosphorylated by both GDNF and NGF, disrupts the RET51/FKBP52 complex. NGF and GDNF have a functional role in dopaminergic (DA) neurons where RET51 and FKBP52 are expressed with a yet undefined function. To clarify if RET51/FKBP52 complex should exert its function in DA neurons, we used an indirect approach by screening the genes encoding for RET51 and FKBP52 in a group of 30 Parkinson's disease patients. The degeneration of DA neurons is the main feature of PD, which is associated to a complex multifactorial aetiology combining environmental, age-related and genetic factors. We found a compound heterozygous carrying two mutations in RET and FKBP52 that are sufficient to disrupt the RET51/FKBP52 complex, indicating its potential role in PD.

Abstract
BACKGROUND Protein content of preterm human milk (HM) is relatively low and extremely variable among mothers: thus, recommended protein intake is rarely met. OBJECTIVES To evaluate in a NICU setting if HM protein content after standard fortification meets the recommended intake, and also to check the effect of fortification on the osmolality of HM, as an index of feeding intolerance. METHODS Protein content of 34 preterm HM samples was evaluated by a bedside technique (Near-Infrared-Reflectance-Analysis - NIRA); osmolality was also checked. Seventeen samples were fortified with Aptamil BMF, Milupa (Group A) and 17 with FM85, Nestlé (Group B). Fortification was performed as recommended by the manufacturer ("full fortification [FF]") and also with a lower amount of fortifier ("low-dose fortification [LF]"). After fortification, actual protein content was calculated and compared to that needed to meet recommended intake (2.33-3g/dl), and osmolality was measured. RESULTS After FF, protein content was above 3g/dl in none of the samples, and below 2.33 g/dl in 16/34 samples (11 in Group A, 5 in Group B). After LF, protein content was above 3g/dl in none of the samples and below 2.33 g/dl in 32/34 samples (15 in Group A, 17 in Group B). Osmolality exceeded 400 mOsm/kg in 19 samples after FF (10 in Group A, 9 in Group B) and in 2/34 samples after LF (1 in each group). CONCLUSION HM protein content after standard fortification fails to meet the recommended intake for preterm infants in approximately half of the cases.

Abstract
A study was conducted in subjects admitted to hospital for chronic obstructive bronchopulmonary disease (COPD) in the city of Parma (Italy). The aim was to evaluate changes in patients' percent vital capacity (VC), forced vital capacity (FVC) and forced expiratory volume in one second (FEV1), as a function of changing degrees of atmospheric pollution as measured by PM10, NO2 and O3 concentrations in the outside air. Study results revealed an association between PM10 concentrations and hospital admissions for COPD. Statistically significant differences were found between PM10 concentrations measured three-four days before admission and in days not followed by admission to hospital. Regression analysis between PM10 concentrations at 24, 48, 72, and 96 hours before admission and respiratory function showed a significant association between FVC% and FEV1% and PM10 concentrations at 96 hours. The relative risk was calculated to be 1.016 (95% confidence intervals: 1.001-1.032), which corresponds to a 1.6% increased risk of admission to hospital for COPD for each unit increase in PM10 concentration in the outside air.

Abstract
An investigation by electron backscatter diffraction on gypsum shows that this technique can be used to study the microstructures and crystallographic preferred orientation of gypsum. Presented here are the methods, verification tests and data obtained from a naturally deformed sample of gypsum-rich rock. The electron backscatter diffraction data show the sample has a strong crystallographic preferred orientation.

Abstract
Gastro-oesophageal reflux (GOR) is common in preterm infants. Combined multichannel intraluminal impedance and pH monitoring (pH-MII) is emerging as an useful tool to study both acid and non-acid GOR in this population. We aimed to highlight main advantages and limits of pH-MII in preterm infants and to test whether the inclusion of GOR episodes detected only by pH monitoring details better the features of GOR. Fifty-two symptomatic preterm infants underwent a 24-hour, continuous and simultaneous measurement of pH-MII. Each layout was analyzed using two different options: option 1 included GOR episodes detected by MII and then classified as acid or non-acid according to the associated pH change; option 2 included GOR episodes detected by MII and also GOR episodes detected only by pH sensor. By adopting option 1, a total number of 2834 GOR episodes was detected by MII: 2162 of them were characterized as non-acid and 672 were characterized as acid. The median (range) number of acid MII-GOR episodes was 10 (1-52); the median (range) number of non-acid MII-GOR episodes was 36.5 (2-119). Median (range) acid MII-GOR-bolus exposure index was 0.28% (0.02-2.73%); median (range) non-acid MII-GOR-bolus exposure index was 1.03% (0.06-38.15%). By adopting option 2, an average of 53.2 acid GOR episodes and an average of 11% oesophageal exposure to acid GOR more than by option 1 was detected. An accurate and detailed description of GOR in preterm infants can be obtained only by including in the analysis all acid GOR episodes detected by pH sensor.
