Electrode impedance (EI) is the first objective assessment carried out during the surgical procedure and follow-up of cochlear implanted patients. This measure provides information on the integrity of electrodes and on the surrounding environment. It is one of the main factors responsible for energy consumption of the cochlear implant (CI). The aim of our study is to investigate changes over time in EI in adult recipients implanted with the perimodiolar array by comparing differences in various cochlear segments. In addition, we explore the relationship between these objective measures and subjective measures such as T-level and C-level. We studied 28 adult patients. Impedance values (IVs) were calculated in “common-ground” (CG) and in monopolar (M1+2) mode for electrode groups in basal middle and apical segments. We found significant decreases in IVs between activation and 1 month. We obtained higher values for basal impedance, whereas lower IVs were found for apical electrodes at all observation times. Statistical pairing over time between impedance and T/C values showed significant correlation for both global impedance (GI) and T-C levels at CG and M1+2 mode up to 6 months. Segregated statistical analysis also showed a significant and prolonged correlation of basal IVs and fitting parameters. The higher basal impedance over time can be explained by the higher proportion of newly formed tissue in this region. The linear correlation of impedances with the fitting parameters become not significant after 3/6 months for the apical and middle segments and remained significant only for the basal region over time. This behaviour underlines the importance of persistence in intra-cochlear factors in influencing fitting parameters in the basal segment. © 2017, Pacini Editore S.p.A. All rights reserved.

BACKGROUND AND OBJECTIVES: Gastric acidity is a major nonimmune defense mechanism against infections. The objective of this study was to investigate whether ranitidine treatment in very low birth weight (VLBW) infants is associated with an increased risk of infections, necrotizing enterocolitis (NEC), and fatal outcome. METHODS: Newborns with birth weight between 401 and 1500 g or gestational age between 24 and 32 weeks, consecutively observed in neonatal intensive care units, were enrolled in a multicenter prospective observational study. The rates of infectious diseases, NEC, and death in enrolled subjects exposed or not to ranitidine were recorded. RESULTS: We evaluated 274 VLBW infants: 91 had taken ranitidine and 183 had not. The main clinical and demographic characteristics did not differ between the 2 groups. Thirty-four (37.4%) of the 91 children exposed to ranitidine and 18 (9.8%) of the 183 not exposed to ranitidine had contracted infections (odds ratio 5.5, 95% confidence interval 2.9-10.4, P < .001). The risk of NEC was 6.6-fold higher in ranitidine-treated VLBW infants (95% confidence interval 1.7-25.0, P = .003) than in control subjects. Mortality rate was significantly higher in newborns receiving ranitidine (9.9% vs 1.6%, P = .003). CONCLUSIONS: Ranitidine therapy is associated with an increased risk of infections, NEC, and fatal outcome in VLBW infants. Caution is advocated in the use of this drug in neonatal age.

Purpose of review In the last years, the perioperative use of levosimendan in cardiac surgery patients is spreading. Moreover, newer indications have been suggested such as the treatment of sepsis-associated myocardial dysfunction. In the present review, we discuss the most recent evidences in these settings. Recent findings Levosimendan has been seemingly confirmed to reduce mortality in patients undergoing cardiac surgery. In particular, it appears to be the only inotropic drug to have a favorable effect on survival in any clinical setting. Moreover, levosimendan has been shown to exert a cardioprotective action and to reduce acute kidney injury, renal replacement therapy, and ICU stay in cardiac surgery patients. Finally, levosimendan has been suggested to reduce mortality in patients with severe sepsis and to improve renal outcomes in critically ill patients. Summary Although a strong rationale likely exists to use levosimendan in the setting of perioperative and critical care medicine, evidence mainly comes from small and often poor-quality randomized clinical trials, whose results acquire significance only when pooled in meta-analyses. Moreover, some aspects related to which subgroups of patients may derive the most benefits from receiving levosimendan, to the optimal timing of administration, and to the potential adverse effects need to be further clarified. Important insights will be hopefully provided soon by the several large multicenter investigations which are currently ongoing. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.

Hernia | Year: 2013

Purpose: The laparoscopic treatment of ventral incisional hernias is the object of constant attention and is becoming increasingly widespread in the international scientific-surgical community; however, there is ample debate on its technical details and indications. In order to establish a common approach on laparoscopic ventral incisional hernia repair, the first Italian Consensus Conference was organized in Naples (Italy) on 14-15 January 2010. Methods: The format of the Consensus Conference was freely adapted from the standards of the National Institute of Health and the Italian Health Institute. The parties involved included the followings: a Promotional Committee, a Scientific Committee, a group of Experts, the Jury Panel and a Scientific Secretariat. Results: Eleven statements, regarding three large chapters on the indications, the technical details and the management of complications were drafted on the basis of literature references collected by the Scientific Committee, documents developed by the Experts, reports presented and discussed during the Consensus Conference, and discussion among the members of the Jury. Conclusions: The laparoscopic approach is safe and effective for defects larger than 3 cm in diameter; old age, obesity, previous abdominal operations, recurrence and strangulation are not absolute contraindications. Ensuring an adequate overlap, careful adhesiolysis and correct fixing of the prosthesis are among the technical details recommended. Complications and recurrences are comparable to, and in some cases, less numerous than with the open approach. © 2013 Springer-Verlag France.

Purpose of review For over a decade, the importance of zinc in the treatment of acute diarrhea has beenrecognized. More recently, the mechanisms of action of zinc are becoming clearer. This review is focused on the new evidence on the mechanisms of action of zinc in acute diarrhea. Recent findings The vast majority of data derive from in-vitro studies using intestinal cell lines or from animal model. The positive action by zinc in acute diarrhea derives from a regulation of intestinal fluid transport, mucosal integrity, immunity, gene expression, and oxidative stress. A complex homeostatic network is also able to regulate zinc status at cellular and extracellular level. Summary All these data support the use of zinc in the treatment of acute diarrhea, but further clinical studies are needed to explore the selective effects of zinc against specific pathogens responsible for diarrhea. © 2010 Wolters Kluwer Health.

Purpose: To evaluate the anatomic and functional results of the treatment with intravitreal bevacizumab in complicated retinal arterial macroaneurysm (RAM). Design: A multicenter interventional, prospective, nonrandomized study. Methods: Thirty-eight macroaneurysms of 37 patients with foveal complications were evaluated. All patients underwent a comprehensive ophthalmologic examination, fluorescein angiography (FA), and spectral-domain optical coherence tomography (SD OCT) examination. Each patient underwent 3 monthly injections of bevacizumab 1.25 mg/0.05 mL; 3 follow-up visits were planned at week 2, 6, and 12. Results: Both best-corrected visual acuity (BCVA), expressed in logarithm of minimal angle of resolution (logMAR), and central retinal thickness (CRT) significantly improved during the follow-up visits (0.57 ± 0.21 vs 0.41 ± 0.15 vs 0.23 ± 0.13 vs 0.09 ± 0.10 and 520.38 ± 191.05 vs 396.24 ± 136.18 vs 283.86 ± 71.87 vs 214.84 ± 26.86, respectively, Friedman test P <.0001 for all variables). At 6 weeks of follow-up, FA showed complete closure of the RAM in 36 of 38 cases (94.7%). Four weeks following the third injection, the macular edema had completely resolved and hard exudates regressed slowly in 100% of patients. Conclusions: Intravitreal bevacizumab is an effective therapy for complicated RAM, quickly improving BCVA and CRT. Anti-vascular endothelial growth factor (VEGF) drugs might actively close the involved pathologically permeabilized retinal artery and normalize the vessel wall formation by localized inhibition of VEGF. © 2013 Elsevier Inc.

Objective:To investigate whether creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) can be used to predict neurodevelopmental outcome at 18 months in infants with perinatal asphyxia (PA). The diagnostic value of cTnI to assess myocardial dysfunction was considered as well.Study Design:Retrospective study of 178 neonates admitted with PA. cTnI concentrations measured within 12 h of birth were compared with medium-term outcome assessed with the Bayley Scales of Infant Development. cTnI concentrations measured within 12 h of birth were compared with clinical grade of hypoxic-ischemic encephalopathy (HIE) and with duration of inotropic support. Two-dimensional Doppler and color Doppler findings were recorded. Fractional shortening, tricuspid and mitral regurgitation were evaluated.Result:A statistically significant correlation between cTnI concentration and BSID-II score was found (mental development index r -0.69, P<0.05 and psychomotor development index r -0.39, P<0.05). There was no statistically significant correlation between CK-MB and BSID-II score (P>0.05).Serum cTnI concentrations and duration of inotropic support were significantly greater with increasing severity of PA. cTnI was negatively correlated with fraction shortening (r -0.64; P<0.05). The severity of tricuspid regurgitation was correlated with the cTnI concentration (r 0.61; P<0.05).Conclusion:In asphyxiated neonates, cTnI concentrations within 12 h of birth correlate with medium-term outcome. Early cTnI concentration correlates with severity of HIE, myocardial dysfunction and with Bayley II scores at 18 months. © 2014 Nature America, Inc.

Background: The aim of this study was to assess systolic left atrial (LA) reservoir function in patients with mitral stenosis (MS) using two-dimensional (2D) strain (ε) and strain rate imaging and its prognostic value in predicting atrial fibrillation (AF) at 4-year follow-up. Methods: One hundred one asymptomatic patients with pure rheumatic MS and 70 healthy controls were evaluated using standard Doppler echocardiography (mitral valve area, mean gradient, systolic pulmonary pressure, LA width, LA volumes, and LA ejection fraction) and 2D speckle-tracking. Results: LA width, volumes, and systolic pulmonary pressure were significantly increased (P <.0001), and LA 2D ε and strain rate were significantly impaired in patients with MS (P <.0001). At 4-year follow-up, 20 patients (20%) showed AF on standard electrocardiography or 24-hour Holter electrocardiography. Patients with MS who had AF were older than those who did not, without significant differences in LA dimensions, volumes, ejection fraction, and compliance index. Instead, atrial myocardial systolic 2D ε was significantly impaired in patients with events. On multivariate analysis (age, LA volume, planimetric mitral area, average annular Ea, and LA strain) the best predictor of AF was average LA peak systolic ε (coefficient, 0.43; SE, 0.098; P < .01), with an area under the receiver operating characteristic curve of 0.761 (SE, 0.085; 95% confidence interval, 0.587-0.888, P =.002) for a cutoff value of 17.4%. Conclusions: The results of 2D ε imaging are abnormal in patients with asymptomatic MS and predict AF at 4-year follow-up.Copyright 2013 by the American Society of Echocardiography.

Background In recent years, new devices providing multiple channels have made the performance of laparoscopic cholecystectomy through a single access site not only feasible but much easier. The potential benefits of laparoendoscopic single-site (LESS) cholecystectomy may include scarless surgery, reduced postoperative pain, reduced postoperative length of stay, and improved postoperative quality of life. There are no comparative data between LESS cholecystectomy and standard laparoscopic cholecystectomy (LC) available at present with which to quantify these benefits. Methods This study was a prospective, randomized, dual-institutional pilot trial comparing LESS cholecystectomy with standard LC. The primary end point was postoperative quality of life, measured as length of hospital stay, postoperative pain, cosmetic results, and SF-36 questionnaire scores. Secondary end points included operative time, conversion to standard LC, difficulty of exposure, difficulty of dissection, and complication rate. Results No significant differences in postoperative lengths of stay were found in the two groups. Postoperative pain evaluation using a visual analogue scale showed significantly better outcomes in the standard LC arm on the same day of surgery (P =.041). No differences in postoperative pain were found at the next visual analogue scale evaluation or in the postoperative administration of pain-relieving medications. Cosmetic satisfaction was significantly higher in the LESS group at 1-month follow-up (mean, 94.5 ± 9.4% vs 86 ± 22.3%; median, 100% vs 90%; P =.025). Among the 8 scales of the SF-36 assessing patients' physical and mental health, scores on the Role Emotional scale were significantly better in the LESS group (mean, 80.05 ± 29.42 vs 68.33 ± 25.31; median, 100 vs 66.67; P <.0001). Conclusions In this pilot trial, LESS cholecystectomy resulted in similar lengths of stay and improved cosmetic results and SF-36 Role Emotional scores but performed less well on pain immediately after surgery. A larger multicenter trial is needed to confirm and further investigate these results. © 2011 Elsevier Inc. All rights reserved.

In patients with a cochlear implant (CI), the first critical point in processing auditory information from sound stimuli that leads to comprehension is the interface between the electrode and the cochlear nerve, which is dependent on providing appropriate current input. The purpose of this work was to evaluate the longitudinal differences in psychoacoustic fitting parameters in CI users. We studied 26 profoundly deaf adults, aged between 18 and 58 years, who had been implanted in our department between 2009 and 2011. The lowest current levels that evoked an auditory sensation (T-level) and the highest current levels that did not elicit an uncomfortable loud sensation (C-level) were recorded at the time of activation, approximately 30 days after implantation (mean 28.5 days) (T0), after one month (T1), 3 months (T3), 6 months (T6) and one year (T12). Impedance values were calculated for electrode groups: basal, middle and apical. In all cases, the same model of perimodiolar implant (Cochlear™ Nucleus® CI24RE) and the same surgical technique (cochleostomy) were used. The values of T-level and C-level showed significant incremental changes between T0 and T1 and between T1 and T3. T-levels in the basal regions of the cochlea were higher than in other sites. T-levels in the basal turn exhibited higher values consistent with a greater amount of fibrosis, as reported in other studies. Our findings suggest that fitting sessions should be scheduled more frequently during the first three months as indicated by the greater slope of T- and C- level variations during that time frame.
