Nanosilver Dressing in Treating Deep II Degree Burn Wound Infection in Patients with Clinical Studies

Background. Patients’ clinical antibiotic treatment of deep II degree burns usually fails to achieve the ideal effect; in order to avoid the late result in pigmentation, scarring, and even limb dysfunction, it also needs to deal effectively with burn wounds. Aim. The purpose of this study is to evaluate nanosilver dressing in treating deep II degree burn wound infection in patients with clinical studies. Materials and Methods. 106 burn patients were classified into the Sulfadiazine Silver Cream (SSC) group ( n = 53 ) and the Nanosilver Burn Dressing (NSBD) group ( n = 53 ). Both of them received basic wound treatment, and wound healing time and pigmentation fading away time of all patients were recorded. And the wound healing rate of the patients was calculated. Serum levels of tumor necrosis factor alpha (TNF-α) and interleukin-1beta (IL-1β) were detected pre- and posttreatment. Results. After basic treatment for all patients, Sulfadiazine Silver Cream was used in the SSC group, and Nanosilver Burn Dressing was used in the NSBD group. It was observed that after treatment, compared with the SSC group, there was significant efficiency; wound healing rate, healing time, and pigmentation fading away time were shortened in the NSBD group, and IL-1β levels were decreased, and the positive rate of bacterial culture was decreased (all P < 0.05 ). Conclusion. Nanosilver Burn Dressing in treating deep II degree burns can effectively reduce the wound infection and promote wound healing. The curative effect was distinct, which was worthy of popularization and application.

The immediate and late results for balloon angioplasty of native coarctation of aorta in pediatrics age group

Background: percutaneous balloon dilation of corotation of aorta is a less invasive and alternative to surgical repair for patients with discrete coaction of aorta and although the used of balloon angioplasty in patients with recurrent postoperative coarctation gained a wide consensus, the use this technique for native coarctation is still controversial in children less one years. Objective: to evaluate the immediate and late result of balloon dilation of native coarctation of aorta in infant and children. Type of the study: A prospective study. Subjects & Methods: The study was done on forty-five patients who were referred for cardiac catheterization and balloon angioplasty of native coarctation of the aorta at Ibn-AL-Bitar center for cardiac surgery between January 2015 to May 2016.Left heart catheterization was performed with evaluation of the morphology and pressure gradient across the stenotic segment of aorta. Follow up evaluations were done between 1 week and 18 months after discharge (mean 6 months) with transthoracic echocardiography. Results: The age of patients range from 1month to 4 years (median age at time of procedure was12.3month). Associated lesions in 11 patients (24.4%). Immediate results were reduction in gradient from 42.5± 17.3 to 10.3± 8.2 mm Hg in forty-two patients (93.3%). Late result during follow up period, 29 patients (69%) had maintain gradient less than 20mmHg. Complications were reported in 6 patients (13.3%). there was one procedure related death (2.2%). Conclusions: Balloon angioplasty for treatment of native coarctation of the aorta is effective with sustained benefit on long-term follow-up in infants and children >6 months. Transverse arch hypoplasia and children <6 months old has major effect on late outcome of recurrent coarctation of aorta.

Effects of Early- and Late-Arriving Room Reflections on the Speech-Evoked Auditory Brainstem Response

Room reverberation alters the acoustical properties of the speech signals reaching our ears, affecting speech understanding. Therefore, it is important to understand the consequences of reverberation on auditory processing. In perceptual studies, the direct sound and early reflections of reverberated speech have been found to constitute useful energy, whereas the late reflections constitute detrimental energy.This study investigated how various components (direct sound versus early reflections versus late reflections) of the reverberated speech are encoded in the auditory system using the speech-evoked auditory brainstem response (ABR).Speech-evoked ABRs were recorded using reverberant stimuli created as a result of the convolution between an ongoing synthetic vowel /a/ and each of the following room impulse response (RIR) components: direct sound, early reflections, late reflections, and full reverberation. Four stimuli were produced: direct component, early component, late component, and full component.Twelve participants with normal hearing participated in this study.Waves V and A amplitudes and latencies as well as envelope-following response (EFR) and fine structure frequency–following response (FFR) amplitudes of the speech-evoked ABR were evaluated separately with one-way repeated measures analysis of variances to determine the effect of stimulus. Post hoc comparisons using Tukey’s honestly significant difference test were performed to assess significant differences between pairs of stimulus conditions.For waves V and A amplitudes, a significant difference or trend toward significance was found between direct and late components, between direct and full components, and between early and late components. For waves V and A latencies, significant differences were found between direct and late components, between direct and full components, between early and late components, and between early and full components. For the EFR and FFR amplitudes, a significant difference or trend toward significance was found between direct and late components, and between early and late components. Moreover, eight, three, and one participant reported the early, full, and late stimuli, respectively, to be the most perceptually similar to the direct stimulus.The stimuli that are acoustically most similar (direct and early) result in electrophysiological responses that are not significantly different, whereas the stimuli that are acoustically most different (direct and late, early and late) result in responses that are significantly different across all response measures. These findings provide insights toward the understanding of the effects of the different components of the RIRs on auditory processing of speech.

The Almacık mafic-ultramafic complex: exhumed Sakarya subcrustal mantle adjacent to the İstanbul Zone, NW Turkey

The Almacık Mountains in northwestern Turkey expose an upper-amphibolite-facies complex consisting of alternating ultramafic (harzburgitic and websteritic) and mafic (metagabbroic) rock types. In the eastern part of this complex are island arc meta-tholeiites and transitional to calc-alkaline metabasites that are chemically quite similar to those of the Permo-Triassic Çele mafic complex north of Bolu, and this suggests an equivalence. However, much of the section exposes structurally deeper and chemically different mafic and ultramafic rocks, which have no equivalent in the Çele mafic complex, and isotopic dating has suggested that these rocks also formed during the Permian period and underwent Triassic and Jurassic metamorphism. Furthermore, sparse inherited ages, unlike those from İstanbul Zone granitoids, suggest a link with North African-derived Armorican-type basement (and hence the Sakarya Zone), rather than Amazonia-derived Avalonian basement. Alternating mafic and ultramafic rocks suggest structural repetition, supported by the exposure of discrete high-strain zones or poorly exposed shattered rock west of each outcrop of ultramafic rocks. The high grade of metamorphism, and the absence of either extrusive lavas or sheeted dyke rocks, suggests that the Almacık complex was not an ophiolite, but formed instead as subcontinental lower crust and subjacent mantle. Dominantly calc-alkaline geochemistry suggests that it formed the basement to an active continental margin bounding the north side of the Sakarya Continent, with S-dipping subduction of Palaeotethys. The Almacık complex was uplifted as a late result of compression against the southern margin of the İstanbul Zone in the Jurassic period. Lack of coeval high-grade metamorphism in the İstanbul Zone indicates that the latter was overthrust southwards over the Sakarya margin, and that there was therefore a change of subduction polarity in the Triassic period. The evidence further casts doubt on the existence of a Mesozoic Intra-Pontide Ocean in northwestern Turkey and suggests that the latest Permian magmatism, with subsequent Triassic and Jurassic metamorphism, was instead related to the closure of the Palaeotethyan Ocean.

The sacral revolution: the synthesis of analysis, religion and radical politics. Origins and reception

Following a brief introduction to the philosophical climate of the nineteenth century, and understanding psychoanalyis as a late result of the Enlightenment, in the historical first part of this article, the author traces the origins of an opposing tradition that is nearly as old as analysis itself: the synthesis of analysis, religion and radical politics. This synthesis was originally conceived during the meeting, some hundred years ago, of the psychoanalyst Otto Gross with the anarchist Erich Mühsam and his partner, the religious scholar Johannes Nohl, in the Swiss village of Ascona. At the start of modernity, in their first attempts at resacralizing both politics and analysis, these concepts form the very beginnings of a postsecular thinking and in this they point beyond the postmodern. A second part presents the reception of these ideas, before the article concludes with a critical evaluation from today's perspective.
