Use of a Partial-thickness Flap for Guided Bone Regeneration in the Upper Jaw
Authors: Busa Alberto , Caccianiga Gianluigi 
Published: December 2017

ABSTRACT

Introduction
Guided bone regeneration (GBR) aims to restore adequate bone volume for the placement of implants in an ideal location. In this article, we analyze different surgical techniques for tissue management during GBR and a modified partialthickness surgical approach.

Materials and methods
In a year's time span, five patients were enrolled in the study: Four women and one man (aged 44–59 years). In four patients, a GBR with simultaneous implant placement was adopted, whereas in another patient, a delayed implant placement was done. The flap was of full thickness and overturned on the side palatal with the aim of a retractor, thus exposing the bone crest. The graft material was covered and protected with a resorbable collagen membrane (Geistlich Bio- Gide®, Switzerland). The periosteal layer of the flap was then positioned above the resorbable membrane without traction. The sutures as vertical mattress were then positioned. Each patient received an intramuscular betamethasone dose (4 mg/50 kg) and antibiotic therapy for 7 days (amoxicillin + clavulanic acid 1 gm every 12 hours) and was instructed to maintain oral hygiene and appropriate wound cleaning. The patients were recalled at different times to monitor the healing.

Results
No cases of tissue dehiscence were observed during the period of wound healing. One patient, however, showed a delayed exposure 4 months after surgery. This occurrence was managed without complications for the patient.

Conclusion
The design of proposed flap seems to be effective in controlling the risk of dehiscence during the healing time in the GBR. The vascular supply was rarely compromised. The results we obtained are encouraging even if further studies on this technique are needed.

Clinical significance
Lateral partial-thickness flaps seem to be effective in controlling tissue tension and consequently the risk of dehiscence. The incision vestibularly performed should favor the soft tissue healing.

ABSTRACT

Aim
This study aimed to estimate the frequency of oral lesions in dermatological diseased patients attending the outpatient department of Pravara Rural Medical and Dental College and Hospital, Pravara Institute of Medical Sciences (Deemed University), Loni, Ahmednagar, Maharashtra, India, and the Department of Dermatology at Medical College, Ahmednagar, Maharashtra, India.

Materials and methods
A cross-sectional hospital-based study was conducted in Loni from October 2013 to January 2014. A total of 310 patients (mean age 37.2 ± 16 years, 61.2% males) completed an oral examination and a personal interview. Oral lesions were recorded. Biopsy and smear were used as adjuvant techniques for confirmation. Data were analyzed using Statistical Package for the Social Sciences (SPSS) (version 15.0.1).

Results
Of 310 cases (n = 310) observed for skin lesions, 99 cases were psoriasis (31.93%) and 68 cases were lichen planus (LP; 21.9%), followed by herpes zoster in 44 cases (14.1%), herpes simplex in 13 cases (4.1%), pemphigus vulgaris (PV) in 15 cases (4.8%), erythema multiforme (EM) in 8 cases (2.5%), bullous pemphigoid (BP) in 4 cases (1.2%), chicken pox in 3 cases (0.9%), eczema in 52 cases (16.7%), and nutritional deficiency and candidiasis in 2 cases (Table 1).

Conclusion
The dermatologic diseases studied frequently occur in the oral cavity. Among them, psoriasis was the most common dermatological disease, and LP frequently showed.

Clinical significance
This study also depicts that diagnosis and management of these oral lesions should also be carried out by oral clinicians so as to improve the oral health functioning during the course of the disease. The intraoral examination should be incorporated to the routine of dermatologic assistance as the oral manifestations can represent preliminary signs or can coexist with the diseases.

Identifying Pediatric Trauma Data Gaps at a Large Urban Trauma Referral Center in Santiago, Chile
Authors: St-Louis Etienne , Roizblatt Daniel , Deckelbaum Dan L , Baird Robert , Millán César V , Ebensperger Alicia 
Published: December 2017

ABSTRACT
Background
Trauma registries contribute to improving trauma care, but their impact is highly dependent on the quality of the data. A simplified point of care pediatric trauma registry (PTR) was developed at the Centre for Global Surgery from the McGill University Health Centre (MUHC) for implementation in Low-middle income countries (LMICs). Pilot deployment was launched at a large urban trauma center in May 2016 in Santiago, Chile. Prior to deployment, we sought to identify missing data in existing trauma records in order to optimize PTR practicality and user benefit.

Materials and methods
The project was approved by the local Institutional Review Board. Retrospective chart review was conducted on trauma patients below the age of 15 who were evaluated at the emergency room (ER) of Hospital Dr. Sotero del Rio (HSR) between January 1st and June 30th 2015. Data missingness was evaluated for each component of the PTR (demographics, mechanism, injury and outcomes). Potential independent predictors of data missingness were evaluated using multiple linear regression.

Results
A total of 351 patients were included. Demographic data missingness ranged from 0% (age) to 95% (mode of arrival). Mechanism data missingness ranged from 6% (cause of injury) to 42% (site of injury). Injury physiology data missingness ranged from 37% (oxygen saturation) to 99% (respiratory rate). Interestingly, mean injury anatomy data missingness was significantly inferior to physiology data (0.6% vs. 78.6%, p < 0.05). Outcome data missingness reached 54% at 2 weeks.

Conclusion
In resource-limited settings, high quality data is essential to guide responsible resource allocation. We believe implementation of a simplified trauma registry has the potential to reduce data gaps for pediatric trauma patients by streamlining trauma data collection at point of care. This should include streamlined data collection with a short per-patient completion time, and should forego attempts to collect data at 2 weeks, which has proven unsuccessful.

RESUMO
Objetivo
Elucidar as características e o padrão epidemiológico dos acidentes com escorpião no ano de 2015 atendidos em um hospital de trauma terciário.

Materiais e métodos
Estudo epidemiológico, retrospectivo e descritivo, a partir de dados de notificação de acidentes escorpiônicos do Sistema de Informação de Agravos de Notificação (SINAN) sendo a coleta de dados feita por meio da Unidade de Toxicologia da instituição (CEATOX) e Núcleo Hospitalar de Epidemiologia (NUHEPI), referentes ao ano de 2015.

Resultados
No ano de 2015, 2652 vítimas de acidentes com escorpiões receberam auxílio médico no pronto atendimento do hospital de trauma em questão. Deste número, 1721 (64,9%) eram do sexo masculino. A capital, Fortaleza, era o município de residência de 2.465 (92,9%) dos pacientes. As regiões corpóreas mais acometidas foram pé e mão, ambos com 885 (33,4%) dos casos. Não foi necessária a infusão de soro antiescorpiônico em nenhuma ocasião. Ademais, em 2647 (99,8%) o acidente foi categorizado como leve.

Conclusão
Essa amostragem demonstra a ainda grande prevalência dessa causa externa de trauma no estado do Ceará, condição essa que pode acarretar risco de lesão grave de membros e complicações graves, incluindo o óbito. O agravo está, também, estreitamente relacionado com questões ambientais e com a falta de conhecimento da população sobre os aspectos da prevenção, tornando o profissional de saúde um agente transformador na redução dos índices e redução da demanda hospitalar pelos casos.

Significância clínica
Embora a maior parte dos acidentes com escorpião seja classificada como leve, alguns indivíduos, principalmente crianças e idosos, podem evoluir com quadros graves que terminem em óbito. Tornam- se assim imperativos tanto a implementação de medidas preventivas como o correto manejo clínico de cada caso.

Published: December 2017

Abstract. A new IASI methane product developed at the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) is presented. The retrievals are performed with the ASIMUT-ALVL software based on the optimal estimation method (OEM). This paper gives an overview of the forward model and retrieval concept. The usefulness of reconstructed principal component compressed (PCC) radiances is highlighted. The information content study carried out in this paper shows that most IASI pixels contain between 0.9 and 1.6 independent pieces of information about the vertical distribution of CH4, with a good sensitivity in the mid- to upper troposphere. A detailed error analysis was performed. The total uncertainty is estimated to be 3.73 % for a CH4 partial column between 4 and 17 km. An extended validation with ground-based CH4 observations at 10 locations was carried out. IASI CH4 partial columns are found to correlate well with the ground-based data for 6 out of the 10 Fourier transform infrared (FTIR) stations with correlation coefficients between 0.60 and 0.84. Relative mean differences between IASI and FTIR CH4 range between −2.31 and 4.04 % and are within the systematic uncertainty. For 6 out of the 10 stations the relative mean differences are smaller than ±1 %. The standard deviation of the difference lies between 1.76 and 2.97 % for all the stations.
Up to 10-year follow-up of the Symax stem in THA: a Danish single-centre study
Authors: Edwards Nina M. , Varnum Claus , Kjærsgaard-Andersen Per 
Published: December 2017

Introduction: The design of the cementless Symax-HA femoral stem is based on geometrical analysis of human femoral anatomy to optimise the fit within the femur. The stem combines an anatomical proximal section enabling a metaphyseal anchorage with a straight distal section. This results in an improved proximal load transfer. We aimed to determine the overall survival of total hip arthroplasty (THA) in patients operated at our institution with the Symax stem. Secondly, we investigated the cause of revision for patients having THA including the Symax stem. Methods: The study is a registry study with results from a single centre, Vejle Hospital. From the Danish Hip -Arthroplasty Registry, we identified all THAs operated with the Symax stem. The primary outcome was revision. The secondary outcomes were aseptic loosening, periprosthetic fracture, and all other causes for revision. Results: In total, 1,055 THAs were performed in 875 patients. The median 6.5-year survival rate was 97.5% (95% confidence interval [CI]: 96.6%-98.3%). 29 THAs had undergone revision due to the following causes: periprosthetic fracture (n = 11); aseptic loosening of the cup (n = 1); infection (n = 5); dislocation (n = 10); and component failure (n = 2). There was no revision due to aseptic loosening of the stem. Conclusions: From the Danish Hip Arthroplasty Registry, we identified the overall 6.5-year survival rate to be 95% for cementless THAs. In the present study, the Symax stem has a median 6.5-year survival rate at 97.5% (96.6%-98.3%). No revisions were due to aseptic loosening but the stem had a relative high prevalence of periprosthetic fractures.

Published: December 2017

Background: This paper presents results of in vitro trials of a wearable artificial kidney (WAK). Materials and methods: To carry out the trials, a test bench was developed. It consisted of a patient imitator, a tubing set and measuring equipment. Results: Our WAK can eliminate urea, uric acid and creatinine from spent dialysate with mean mass rates of 0.85 ± 0.1 g/h, 0.10 ± 0.04 g/h and 0.05 ± 0.01 g/h, respectively. Concentrations of Na+, Cl– and Ca2+ ions were kept in the 10% range from initial values. We demonstrated that our WAK can operate for 38 hours without having to replace expendable materials. Conclusions: The WAK that we developed can eliminate metabolites from spent dialysis fluid with mass rates that are sufficient to maintain stable, physiologically normal metabolite concentrations in patients’ blood.

Purpose: Inguinal lymphadenectomy (iLAD) reduces mortality in patients with cN0 penile cancer but yields high complication rates. Thus, its prophylactic role has been questioned and dynamic sentinel node biopsy (DSNB) was introduced to select men who should undergo the procedure. Our aim was to investigate the accuracy of a contemporary DSNB cohort. Methods: We performed a retrospective analysis of ≥T1 or ≥G2 cN0 penile cancer undergoing perioperative DSNB from June 2009 to June 2015 at a tertiary referral center. We excluded men with <18 months follow-up or with local recurrence after primary curative treatment. Complications were graded according to the Clavien-Dindo classification. Results: Thirty-five men underwent DSNB; 85.71% had ≤T2 penile cancer with ≤G2a histology. Per groin detection rate was 80% (scintigraphy being positive bilaterally in 60% and unilaterally in 20.0%). In no cases did DSNB prolong the postoperative course compared to primary surgery. Nine men (n = 15/109 nodes removed) had positive results, 8 of whom underwent iLAD. Among negative DSNB patients, 2 developed nodal penile cancer recurrence; none of them had node biopsy due to inconclusive scintigraphy. At a median follow-up of 42 months (interquartile range 30-78 months), if considering only men with scintigraphy detected inguinal nodes, per-patient sensitivity and specificity were 50% and 80% whereas positive predictive value and negative predictive value were 25% and 92.3%, respectively. Conclusions: Perioperative DSNB is a safe procedure, yielding promising results when performed at a tertiary referral center. Future prospective large studies are needed to investigate how to optimize detection rate and reduce false-negative rates.
The Human Struggle between Darkness and Light: A Virtue Ethic Study of John Steinbeck's The Winter of Our Discontent
Authors: Zheng Li 
Published: December 2017

Abstract
With the American psychologist Erich Fromm's humanistic ethics as a point of reference, this article analyzes The Winter of Our Discontent (1961), John Steinbeck's final work of fiction. This novel focuses on protagonist Ethan Allen Hawley as he succumbs to the influence of corrupt social values and thereby fails to actualize his primary potentiality for goodness. At the novel's end, however, as he is on the verge of suicide, he thinks about the innocence of his daughter, Ellen, and experiences an epiphany of light that leads to a realization of love for self and others. Overcoming his sense of alienation from the good, he embarks on a course of active freedom that will enable him to go on with his life. Steinbeck's exquisite depiction of Ethan's moral development reflects his own ethical concerns about the well-being of his beloved America.
Loading Rate Variations Along a Midcrustal Shear Zone Preceding the Mw6.0 Earthquake of 24 August 2016 in Central Italy

Published: December 2017

AbstractTo identify greater detail in the seismicity pattern preceding the 24 August 2016 Mw6.0 earthquake in Central Italy, we apply waveform matching using 1,028 events as templates. In the 8 months before the mainshock, we find ~2,000 additional earthquakes mostly located along a subhorizontal shear zone (SZ) bounding at depth the extensional fault system. Asynchrony is observed in the occurrence of events nucleating along the SZ compared to the ones on fault portions embedded in the shallower upper crust, with the former anticipating the latter. Within the SZ, we also observe along‐strike seismic migration episodes with earthquakes pointing toward the Mw6.0 mainshock nucleation zone. These episodes are followed by an apparent quiescence within the main fault area. We suggest that the variations in the seismic activity along the SZ represent the brittle signature of the tectonic loading process enabling portions of the overlaying normal faults to become unlocked.

Published: December 2017

AbstractAlthough sediment yield (SY) from water erosion is ubiquitous and its environmental consequences are well recognized, its impacts on the global carbon cycle remain largely uncertain. This knowledge gap is partly due to the lack of soil erosion modeling in Earth System Models (ESMs), which are important tools used to understand the global carbon cycle and explore its changes. This study analyzed sediment and particulate organic carbon yield (CY) data from 1,081 and 38 small catchments (0.1–200 km2), respectively, in different environments across the globe. Using multiple statistical analysis techniques, we explored environmental factors and hydrological processes important for SY and CY modeling in ESMs. Our results show clear correlations of high SY with traditional agriculture, seismicity and heavy storms, as well as strong correlations between SY and annual peak runoff. These highlight the potential limitation of SY models that represent only interrill and rill erosion because shallow overland flow and rill flow have limited transport capacity due to their hydraulic geometry to produce high SY. Further, our results suggest that SY modeling in ESMs should be implemented at the event scale to produce the catastrophic mass transport during episodic events. Several environmental factors such as seismicity and land management that are often not considered in current catchment‐scale SY models can be important in controlling global SY. Our analyses show that SY is likely the primary control on CY in small catchments and a statistically significant empirical relationship is established to calculate SY and CY jointly in ESMs.

Published: December 2017

AbstractThe charge transfer between molecules and materials can modulate the polarizability tensor of the molecules and lead to an enhancement of the Raman scattering. Surface‐enhanced Raman scattering on in‐plane anisotropic layered materials has suggested the crystalline‐axis‐dependent charge interactions between molecules and materials. However, the full understanding of the anisotropic charge transfer process is still lacking. The rigorous anisotropic nature and structural diversity of single‐walled carbon nanotube (SWNT) provide an ideal platform to systematically study the anisotropic charge transfer process. The present work reports the anisotropic Raman enhancement effect of molecules on horizontally aligned SWNT arrays and attribute it to the charge transfer efficiency that depends on the laser polarization direction and the resonance of SWNTs. The Raman signal of probe molecules on SWNT arrays is enhanced and reaches the maximum intensity when the incident laser is polarized along the SWNT axial direction, and the intensity is the minimum if they are perpendicular to each other. The different efficiencies of charge transfer are further confirmed by polarized optical absorption measurements and the energy alignment analysis. The present work provides a sensitive way to study the tunable charge interactions between molecules and anisotropic low‐dimensional materials, which are also important for polarization‐controlled optoelectronic applications.
Experimental study and evaluation of mixing mechanism and performance in triple‐screw extruder
Authors: Yang Kunxiao , Xin Chunling , Yu Dongquan , Yan Baorui , He Yadong 
Published: December 2017

AbstractThe mixing capacity of triangle‐arrayed triple‐screw extruder (TTSE) was evaluated through the extrusion of polypropylene/ethylene–propylene–diene monomer (PP/EPDM) at varying screw speeds. The micromorphology, mean residence time, melt flow rate (MFR), and mechanical properties of blends were measured for evaluation. Moreover, same experiments were applied on a twin‐screw extruder (TSE) for comparison. TTSE shows better mixing performance than TSE in comparison with micromorphology and mean residence time. But the high shear effect and temperature rising in TTSE promote the degradation of PP in blends which make the samples to have worse mechanical properties and higher MFR than those of TSE.
DIN 4109:2016 – Eine technische Regel in der MVV TB?
Authors: Fischer Heinz‐Martin 
Published: December 2017

AbstractDie Muster‐Verwaltungsvorschrift Technische Baubestimmungen (MVV TB) vom August 2017 hat lediglich die DIN 4109‐1 (Mindestanforderungen) als technisches Regelwerk für den baulichen Schallschutz vorgesehen. Ohne als technische Regel genannt zu werden, kann für die rechnerischen Nachweise DIN 4109‐2 in Verbindung mit DIN 4109‐31 bis 36 (Bauteilkatalog) herangezogen werden. Für „Bauteile im Massivbau” ist im Nachweisverfahren aber auch die Verwendung von Beiblatt 1 zu DIN 4109:1989 möglich. Diese alternative Verwendbarkeit neuer und alter Nachweisverfahren und eine Reihe weiterer Festlegungen der MVV TB sorgen bei der Anwendung der Schallschutznachweise im bauaufsichtlichen Bereich für unklare Verhältnisse und erhebliche Probleme. Der Beitrag beschreibt kritisch die Regelungen der MVV TB zum baulichen Schallschutz und erläutert die Probleme, die zu erwarten sind.
