RESUMEN
OBJECTIVE: This study aimed to investigate changes in sleep parameters and self-perceived sleep quality in unilateral vestibular hypofunction participants after vestibular rehabilitation. METHOD: Forty-six unilateral vestibular hypofunction participants (before and after vestibular rehabilitation) along with a control group of 60 healthy patients underwent otoneurological examination, a one-week actigraphy sleep analysis and a series of self-report and performance measures. RESULTS: After vestibular rehabilitation, unilateral vestibular hypofunction participants showed a significant score decrease in the Pittsburgh Sleep Quality Index, a self-rated reliable questionnaire depicting sleep quality during the last month, as well as a reduction in sleep onset latency and an increase in total sleep time, indicating an objective improvement in sleep quality as measured by actigraphy analysis. However, after vestibular rehabilitation, unilateral vestibular hypofunction participants still showed statistically significant differences with respect to the control group in both self-rated and objective measurements of sleep quality. CONCLUSION: Vestibular rehabilitation may impact on sleep performance and chronotype behaviour, possibly by opposing long-term structural changes along neural pathways entangled in sleep activity because of the deafferentation of the vestibular nuclei.

RESUMEN
Umbilical cord hemangioma is an uncommon benign vascular neoplasm arising from the free segment of the umbilical cord, distinct from placental and fetal insertion, and is thought to originate from endothelial cells of the umbilical vessels. Cystic changes in the umbilical cord rarely occur as a consequence of the damage to the amnionic surface of the cord caused by the presence of the hemangioma. Until now, a total of 8 cases of umbilical cord hemangioma associated with cystic changes in the umbilical cord have been reported in the literature, however, among these cases, only one showed an associated cyst derived from inclusion of the amniotic epithelium, and the remaining seven cases consisted of hemangiomas with associated pseudocyst of the umbilical cord. We herein report a case of umbilical cord hemangioma with an associated amnionic epithelial inclusion cyst. Clinicopathological features and differential diagnostic considerations are also discussed.

Zuccagnia punctata Cav. (Fabaceae), a native plant from Argentina has been used traditionally as medicinal species. The aim of the study was to validate the antibiotic and anti-inflammatory potential of Z. punctata organic extract (ZpE) and the major compounds; 2',4'-dihydroxy-3'-methoxychalcone (DHMC), 2',4'-dihydroxychalcone (DHC), 7-hydroxyflavanone (7-HF) and 3,7-dihydroxyflavone (DHF); using an in vitro model. The antibiotic activity was determined using a broth microdilution method and the minimum inhibitory concentration (MIC) was determined. The extract and the isolation compounds affect the normal growth of all assayed Staphylococcus aureus strains. The MIC values for ZpE and isolated compounds were between 125 and 500 µg/mL and between 25 and 400 µg/mL, respectively, against all assayed strains. The inhibitory effect of extract and isolated compounds on biofilm formation and on pro-inflammatory enzymes (sPLA2, COX-2, LOX) was analyzed. The compound DHC was the most active on sPLA2 while DHF and DHMC showed the highest activity on LOX. Both the extract and pure compounds except DHMC were active against COX-2. It can be concluded that the phytocomplex and the pure compounds possessed antibiotic and anti-inflammatory activities under the conditions tested, and could be a good alternative therapy for infective and inflammatory processes.
RESUMEN
Quorum sensing (QS) is a cell-to-cell signaling communication system that controls the virulence behavior of a broad spectrum of bacterial pathogens, participating also in the development of biofilms, responsible of the antibiotic ineffectiveness in many infections. Therefore, QS system is an attractive target for antimicrobial therapy. In this study, we compare the effect of seven structurally related coumarins against bacterial growth, biofilm formation and elastase activity of Pseudomonas aeruginosa. In addition, the anti-pathogenic capacity of the seven coumarins was evaluated on the wild type and the biosensor strain of Chromobacterium violaceum. The comparative study of coumarins showed that molecules with hydroxyl groups on the aromatic ring displayed higher activity on the inhibition of biofilm formation of P. aeruginosa over coumarins with substituents in positions 3 and 4 or without the double 3,4-bond. These 3 or 4-hydroxylated positions caused a decrease in the anti-biofilm activity obtained for coumarin. However, the hydroxyl group in position 3 of the pyrone ring was important for the inhibition of C. violaceum QS and elastolytic activity of P. aeruginosa. The effects observed were active independently of any effect on growth. According to our results, coumarin and its hydroxylated derivatives represent an interesting group of compounds to use as anti-virulence agents against the human pathogen P. aeruginosa.

Five dammarane-type triterpenoids, five pentacyclic triterpenoids (three of them carrying a carboxylic acid group), and two aromadendrane-type sesquiterpenoids were isolated from an Argentinian collection of the liverwort Lepidozia chordulifera. Compounds were characterized by comparison of their spectral data with those previously reported and tested in their ability to control bacterial growth, biofilm formation, bacterial Quorum Sensing process (QS), and elastase activity of Pseudomonas aeruginosa, as well as bacterial growth and biofilm formation of Staphylococcus aureus. The key role played by biofilm and elastase activity in bacterial virulence make them a potential target for the development of antibacterial agents. The aromadendrane-type sesquiterpenoid viridiflorol was the most potent biofilm formation inhibitor, producing 60% inhibition in P. aeruginosa and 40% in S. aureus at 50µg/ml. Ursolic and betulinic acids (two of the pentacyclic triterpenoids isolated) were able to reduce 96 and 92% the elastase activity of P. aeruginosa at 50µg/ml, respectively. Among the analyzed triterpenoids, those that carry a dammarane skeleton were the most potent inhibitors of the P. aeruginosa biofilm formation and were active against both P. aeruginosa and S. aureus. Subsequently, a computer-assisted study of the triterpenoid compounds was carried out for a better understanding of the structure-activity relationships.

The effect of a mixture of potentially probiotic bacteria (MPPB; Lactobacillus reuteri DDL 19, Lactobacillus alimentarius DDL 48, Enterococcus faecium DDE 39, and Bifidobacterium bifidum strains) on the milk fatty acid (FA) profile, with emphasis on cis-9,trans-11 conjugated linoleic acid (CLA) in the middle stage of goat lactation, was determined. In addition, the effects of MPPB feeding on the FA profile in intestinal content and intestinal morphology in weaned goats were analyzed. The probiotic supplement was able to modify FA composition of milk and intestinal content. The unsaturated FA concentrations in milk (g of FA/L of milk) increased from 4.49 to 7.86 for oleic (18:1), from 0.70 to 1.39 for linoleic (18:2), from 0.063 to 0.187 for linolenic (18:3) acid, and from 0.093 to 0.232 for CLA. The atherogenicity index diminished 2-fold after MPPB ingestion. In the intestinal content of the weaned goats, no significant difference in saturated FA concentration compared with the control was observed. However, oleic acid, linolenic acid, CLA, and docosahexaenoic acid concentrations increased by 81, 23, 344, and 74%, respectively, after probiotic consumption. The ruminal production of CLA was increased by the MPPB. However, bacterial strains of MPPB were unable to produce CLA in culture media. By histological techniques, it was observed that the treated group had intestinally more conserved morphological structures than the control group. The results obtained in this study indicate that the MPPB administration in lactating and weaned goats allows for the production of milk with improved concentrations of beneficial compounds, and also produces a protective effect in the goat intestine. The results obtained in this study reinforce the strategy of probiotics application to enhance goat health with the production of milk with higher concentrations of polyunsaturated FA.

BACKGROUND: Several trials showed that early laparoscopic cholecystectomy is superior to delayed laparoscopic cholecystectomy for the treatment of acute cholecystitis. However actual practice does not conform to current evidence. The aim of this study is to compare outcomes and total hospital costs between early and delayed laparoscopic cholecystectomy for acute cholecystitis. PATIENTS AND METHODS: A retrospective analysis of patients with acute cholecystitis that underwent a laparoscopic cholecystectomy at our institutions was performed. Patients were divided into 2 groups on the basis of the treatment received and statistical analysis was performed. RESULTS: The study included 91 patients, 52 female and 39 male, with a mean age of 55. Early surgery was performed in 32 cases and delayed surgery in 59 cases. The two groups were comparable for demographics data and severity of disease on admission. There was a no significant difference (p = 0.174) in the mean operative time between early (54.8 min) and delayed group (47.8 min). Conversion rate was higher in the early group (34.3% vs. 20.3%), but difference was not statistically significant (p = 0.223). The overall complications rate was comparable (18.7% early vs. 16.9% delayed, p = 0.941). Length of postoperative stay (4.3 vs. 3.8 days) was similar (p = 0.437), but total hospital stay was significantly 4 days shorter in the early group (p < 0.0001). The mean total cost was higher for the delayed group (4171 vs. 6041), with a significant difference of 1870 Euro (p < 0.0001). CONCLUSIONS: Early laparoscopic cholecystectomy has an outcome comparable to the delayed procedure, with a shorter total hospital stay and lower total costs, and it should be considered as the preferred approach in treatment of acute cholecystitis.

BACKGROUND: Laparoscopic cholecystectomy has become the standard treatment for symptomatic gallstones. However, a conversion to open surgery is sometimes still required to complete the procedure safely. The aim of this study is to identify the predictive factors of conversion from laparoscopic to open cholecystectomy in both elective and emergency cases. PATIENTS AND METHODS: A retrospective review of all patients underwent laparoscopic cholecystectomy for symptomatic gallstones from January 2011 to October 2013 was performed. Data considered for analysis were: demographic data, comorbidities, preoperative laboratory values, preoperative ERCP, indication for surgery, and the timing of the intervention in acute cholecystitis. Conversion to open cholecystectomy was chosen as the dependent variable for both, univariate and multivariate analysis. RESULTS: 414 patients underwent laparoscopic cholecystectomy. 245 were female (59.1%) and 169 (40.8%) male, with a mean age of 51.7±16.4 years. The indication for surgery was acute cholecystitis in 91 cases (21.9%). Lithiasis of the bile duct was found in 40 patients (9.6%), and it was identified preoperatively in 37 patients, all treated with a preoperative ERCP. Conversion to open occurred in 33 cases (7.9%). Univariate analysis revealed as risk factor for conversion: increased age, acute cholecystitis, comorbidities, elevated white blood cell count, increased level of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transpeptidase, C-reactive protein, and fibrinogen. Multivariate logistic regression analysis showed that acute cholecystitis (OR 5.63) and age > 65 years (OR 3.025) were independent predictive factors for conversion. CONCLUSIONS: These patients should be properly informed of their increased risk of conversion and should be operated by surgeons skilled in laparoscopic procedures to reduce this risk.

AIM: The study compared the efficacy, safety and tolerability of a low-volume picosulphate/magnesium citrate preparation with that of polyethylene glycol plus ascorbic acid (PEG + ASC) in a randomized clinical trial (RCT). METHOD: A multicentre randomized, single-blinded study was designed. Adult outpatients undergoing colonoscopy received either picosulphate/magnesium citrate (Group 1) or PEG + ASC (Group 2). Bowel cleansing was assessed using the Boston Bowel Preparation Scale (BBPS) and rated as adequate if ≥ 2 in each segment. Patient acceptance, satisfaction and related symptoms were recorded. RESULTS: Two-hundred and eighty-five patients were included. Preparation was adequate in 75.7% of patients in Group 1 and in 76.5% of patients in Group 2. The mean BBPS scores for the entire colon and for the right colon were comparable between groups. In addition, 97.1% patients in Group 1 and 84.8% in Group 2 reported no or mild discomfort (P < 0.0003) and 97.8% and 83.4% expressed their willingness to repeat the preparation (P < 0.0001). Palatability was better in Group 1, whereas related symptoms occurred more frequently in Group 2. Regardless of which preparation was used, the split regimen was associated with better cleansing compared with the same-day method (OR = 3.39; 95% CI: 1.1-10.4; P = 0.03). Other predictors of poor cleansing were comorbidity, discomfort during preparation and incomplete (< 75%) preparation. CONCLUSION: Both picosulphate/magnesium citrate and PEG + ASC are effective for bowel preparation. Tolerability and palatability are better for picosulphate/magnesium citrate. A split schedule is associated with higher cleansing quality also for low-volume regimens.

BACKGROUND: The purpose of this study was to compare the microbiota around natural teeth and dental implants with different restorative platforms. Attention was focused on whether the microbiological environment could change according to the implant platform used i.e. traditional or Platform Switching implants. As the latter show less signs of bone resorption, a correlation with the presence of certain periodontal bacteria was suggested. METHODS: Seven partially edentulous patients with dental implants, either traditional or Platform Switching, were included in this study. All the implants were in function at least for 1 year. Gingival crevicular fluid samples were obtained before any periodontal probing from natural teeth and different implant platforms and assayed using DNA extraction and PCR sequences in order to determine quality and quantity of microbiota. Statistical analysis included chi square test were used to establish differences in the microbiological distribution between the two implant platforms. RESULTS: There were not statistical differences neither regarding the distribution of microbiota around natural teeth and implants nor between the two implant platforms. The presence of B.forsythus was revealed in the majority of the samples (from 90 to 100 percent) while A.actinomycetemcomitans was rarely found (from 0 o 25 percent). As for the other periodontal microbiota, their presence or absence showed a variation according to different sites or patients, without a predictable pattern. CONCLUSIONS: It was not possible to find a link between the colonization of certain types of bacteria and the reduction of bone loss which occurs around Platform Switching implants. Therefore the preservation of bone crest is only due to biomechanical aspects, which are related to the reposition of the implant-abutment interface away from the outer edge of the implant platform and from the bone.

Chronic postoperative pain is a common complication of inguinal hernia repair. An important Danish study revealed that 28.7% of patients undergoing hernioplasty suffered a varying degree of chronic pain, severe enough to interfere with normal daily activities in 11% of cases. The difficulty in treating this complication has led numerous surgeons to complete the surgical procedure ilioinguinal or iliohypogastric neurectomy. This method is proving effective in preventing the onset of chronic postoperative pain. We report the results obtained in patients undergoing neurectomy of the iliohypogastric nerve during anterior inguinal hernioplasty.

Laparoscopic surgery plays today an important role in the diagnosis and staging of abdominal lymphomas; in fact it provides adequate lymph node sampling for histological typing and immunophenotyping. The mini-invasive procedure is safe and effective. Intra-operative ultrasound permits to study the parenchimal organs in addition to intra-abdominal lymph node and/or masses.

Small bowel obstruction (SBO) is a very common condition, in the vast majority of cases caused by post-operative adhesions. It often requires surgical treatment. Traditionally, this consisted of a laparotomy, but nowadays a laparoscopic approach is also possible. This study discusses 24 cases of SBO and compares them with literature data. Successful complete laparoscopic treatment was feasible in 9 patients, while conversion to laparoscopically-assisted surgery or laparotomy was required for the others.

BACKGROUND: Angiosarcoma is a highly aggressive soft tissue sarcoma. Responses to anthracyclines plus/minus ifosfamide, and taxanes alone or in combination with gemcitabine are well documented. Very few data are available on gemcitabine as a single agent. PATIENTS AND METHODS: We retrospectively reviewed all cases of advanced progressive angiosarcoma treated with gemcitabine as a single agent (1000 mg/m(2) i.v. every week for 3 weeks every 4 weeks), at Istituto Nazionale Tumori and within the Italian Rare Cancers Network from January 2008 to November 2010. RESULTS: Twenty-five patients [mean age: 52 years; radiation therapy (RT)-related: 8] received gemcitabine. Best tumor response by RECIST was as follows: complete response = 2, partial response = 14, stable disease = 2, progressive disease = 7 cases, for an overall response rate (PR + CR) of 68%. Six of eight post-RT angiosarcomas responded to treatment. Median overall survival (OS) was 17 months. Median progression-free survival (PFS) was 7 months (range 1-40 months). One patient with a locally advanced thyroid angiosarcoma became resectable after 5 months of gemcitabine, with <10% residual viable tumor cells seen on surgical specimen. Overall, gemcitabine was well tolerated. CONCLUSIONS: Gemcitabine is active in both RT- and non-RT-related angiosarcoma, with dimensional and possibly long-lasting responses. A formal phase II study on gemcitabine as a single agent is warranted.

AIMS: Lactobacillus brevis IOEB 9809 is able to produce both tyramine and putrescine via tyrosine decarboxylase and agmatine deiminase enzymes, respectively, when cultured on synthetic media. The aims of this study were to assess the expression of L. brevis IOEB 9809 tdc and aguA1 genes, during wine fermentation and to evaluate the effect of substrate availability and pH on tdc and aguA1 expression, as well as on biogenic amine production and L. brevis viability. METHODS AND RESULTS: The relative expression of L. brevis IOEB 9809 tdc and aguA1 genes was analysed in wine by quantitative real-time RT-PCR (qRT-PCR) during a period of incubation of 30 days. Cell viability, pH values, putrescine and tyramine concentration were monitored throughout the experiments. CONCLUSIONS: The wine trials indicated that L. brevis IOEB 9809 is able to produce both tyramine and putrescine during wine fermentation. Increased cell viability was also observed in wine supplemented with tyrosine or agmatine. qRT-PCR analysis suggests a strong influence of substrate availability on the expression of genes coding for tyrosine decarboxylase and agmatine deiminase in L. brevis IOEB 9809. Less evident is the relationship between putrescine and tyramine production and tolerance to wine pH. SIGNIFICANCE AND IMPACT OF STUDY: To our knowledge, this study represents the first assessment of relative expression of L. brevis IOEB 9809 genes involved in biogenic amine production in wine. Furthermore, an effect of biogenic amine production on viability of L. brevis during wine fermentation was established.

Inguinal hernia repair is one of the most common surgical procedure performed in Western countries and it consumes a lot of healthcare resources. Several types of different mesh are now disposable and tension-free techniques represent the "golden standard". In our study, fifty male patients were operated on for inguinal hernia and a PAD (i.e., dynamic self-regulating prosthesis) used for the repair of the inguinal defect: this technique demonstrated to be safe, effective and easy to perform.
