Bond Strength of Repaired Acrylic Denture Teeth Using Visible Light Cure Composite Resin
Authors: Muhsin Saja Ali 
Published: February 2017

Background:
Although bonding to denture teeth after surface treatment with chemical agents is desirable, there is little information on the use of Visible Light Cure composite resin (VLC) as bonding denture materials.

Objectives:
To determine the effect of various surface treatments on shear bond strength between Visible Light Cure composite resin and the acrylic denture teeth interface.

Methods:
Forty cylindrical sticks of acrylic resin with denture teeth mounted atop were prepared. Various treatments were implemented upon the acrylic resin teeth surfaces. The samples were divided into four groups (n = 10). Light-cured composite resin (LC) was applied over all treated and untreated surfaces of tested groups. The shear bond was tested using a universal tensile testing apparatus with the knife-edge of a 0.8mm shear tester. Data were statistically analyzed using one-way ANOVA performed at a confidence level of 95% and significant P-value of (P ≤ 0.05).

Results:
Analysis of variance (ANOVA) showed statistically significant difference (P < 0.05) between treated and untreated teeth surfaces. The treated surfaces exhibited various levels of bond strength depending on the type of treatment.

Conclusion:
Application of VLC bonding agent with prior treatment of methylmethacrylate (MMA) on the acrylic resin denture teeth resulted in maximum bond strength with composite resin.
Use of Saline as a Placebo in Intra-articular Injections in Osteoarthritis: Potential Contributions to Nociceptive Pain Relief
Authors: Bar-Or David , Rael Leonard T. , Brody Edward N. 
Published: February 2017

Background:
Osteoarthritis of the knee (OAK) is a severe debilitating condition characterized by joint pain, stiffness, and resultant limited mobility. In recent years, intra-articular (IA) injections have been used to relieve symptoms and have succeeded to varying degrees either with sodium hyaluronate preparations or with a biologic.

Objective:
The objective of this review is to evaluate multiple studies that demonstrate some relief from the symptoms of OAK in the saline arm of various clinical trials.

Method:
A thorough literature search (PubMed) was performed assessing the pain efficacy of various compounds compared to saline injections in clinical trials. A total of 73 studies were identified in the literature search including a total of 5,816 patients. These clinical trials all involved the IA injection of a viscosupplement (hyaluronate, platelet rich plasma (PRP), etc.) or a biologic (the low molecular weight fraction (< 5kDa) of human serum albumin (LMWF-5A)). For all of these studies, the control arm was injection of sterile physiological saline that approximates the salt concentration and total solute concentration of blood and most tissues.

Results:
Based on our review of the current literature, the tested compounds performed with mixed results when compared to saline injections. Moreover, OAK is a variable disease, with severity measured on the Kellgren and Lawrence (KL) scale where various hyaluronate preparations have a therapeutic effect mostly on KL 2-3 patients while a biologic works best on KL 3-4 patients.

Conclusion:
Since the effect of saline injection is always greater than no treatment, the evaluations of these treatments can be confounded in clinical trials. Therefore, the question of whether there are known therapeutic effects of saline injections might explain these results.

Within these values the adoption of environmental sustainable management voluntary systems such as ISO 14000 and EMAS has been evaluated and proposed. To this note the Initial Environmental Analysis (IEA) is presented allowing basic targets for improvement and implementation of environmental management programs as well as highlighting the effectiveness of the adoption of sustainable management of voluntary EMAS instrument.
Phases to define and evaluate the environmental factors were analysed and the relationship between the site and the surrounding zone was performed according to the characteristics of “sensitivity” and “vulnerability” of the affected area. Specifying different degrees of priority which the problems must be managed to a medium priority rating was found for short term interventions Some improvements in the hospital waste management were identified among these the preparation of guidelines applicable to current operational practices are the most reliable.
La capacitación como forma de prevención del bullying
Authors: Villalobos Torres Gabriela 
Published: February 2017

El bullying es una problemática social que afecta al alumnado de las diferentes instancias educativas: públicas o privadas, de primaria o secundaria, diurna o nocturna. La reiteración de las acciones y la premeditación de los hechos son elementos clave, a los cuales debe estar atento el personal docente y administrativo para determinar si algún estudiante está siendo víctima de este tipo de violencia. Sin embargo, la prevención es la mejor arma para combatir el bullying, ya que con ella se evitan dolorosas situaciones, tanto para las posibles víctimas como para quien es testigo de estos hechos. El grupo docente no actúa con la pericia debida en algunas situaciones, pues carece de conocimientos que lo faculten para un adecuado abordaje del bullying, ya sea en los niveles de prevención y atención o de seguimiento. De ahí que los procesos de capacitación se convierten en elementos necesarios para subsanar esas debilidades, sobre todo en la sociedad de la tecnología y la información donde los avances en aplicaciones, celulares, móviles, portátiles, juegos por computadoras y otros, se mueven más rápido cada vez.
Aspectos relevantes para la transversalización de la perspectiva de género en el proceso de desarrollo curricular universitario
Authors: Chaves Jiménez Rocío 
Published: February 2017

La transversalidad de género representa la acción de integrar la perspectiva de género en las ideas, prácticas y políticas institucionales, orientándolas hacia el propósito específico de lograr la igualdad entre mujeres y hombres, teniendo en cuenta, en todo momento, la necesidad de identificar los posibles impactos diferenciados sobre unas y otros. Estos impactos pueden conducir a cambiar los roles tradicionales, así como a eliminar las desigualdades de género, o bien, al reforzamiento o perpetuación de aquellas estructuras patriarcales que producen brechas entre mujeres y hombres. Las universidades tienen la responsabilidad de contrarrestar estos efectos de la cultura patriarcal y de evitar cualquier forma de exclusión que se produzca a partir de conclusiones basadas en los estereotipos de género, ya que los currículos que rigen nuestro sistema educativo son de carácter androcéntrico, el cual sitúa a las mujeres en una posición de subordinación y desventaja. Por ende, el trabajo de incorporar la visión de género radicará al menos en considerar los contenidos temáticos de los cursos, los diferentes medios didácticos, el uso de lenguaje inclusivo y no sexista, los diversos procesos de aprendizaje y la política y gestión institucional, con la intención de promover la capacidad crítica y una cultura de igualdad de género, que se origine desde la cotidianidad de la vida universitaria, transformando los sistemas discriminatorios en espacios de igualdad. En fin, la transversalidad de género sería tanto una estrategia metodológica como una estrategia política.
Martín Heidegger: crítica al concepto hegeliano de experiencia (segunda parte)
Authors: García Aguilar Rodolfo 
Published: February 2017

El presente trabajo tiene como objetivo retomar la temática expuesta por Martín Heidegger, en su artículo “El concepto hegeliano de experiencia”, para rescatar sus reflexiones en el campo de la ontología. Se busca abrir nuevamente la discusión en un mundo metafísico donde se consolida lo que el autor llama “la imagen del mundo”, y donde se considera esta, erróneamente, como la única forma de enfrentarse y apoderarse de la realidad.

Published: February 2017

Objective We proposed a novel technique for the quantitative examination of tip recoil. The technique measures nasal tip strain as an objective measure of tip recoil. We used the term tip recoilometry to refer to this measurement technique. Design We performed case studies in two phases. Phase 1 included 30 candidates with normal tip recoil and 30 candidates with weak tip recoil. Phase 2 included 40 patients who had undergone open rhinoplasty surgery by either columella strut or caudal extension graft methods. We evaluated tip support of patients 1 year after the surgery. Results The nasal tip strain of normal target group before any surgery was 0.158 and that of the patients with nasal tip ptosis was 35% more than that of the normal target group. The methods columella strut and caudal extension graft achieved 43% and 74% nasal tip strain reduction, respectively. Conclusion The proposed technique can help a surgeon to select a proper plan and to evaluate the success of the surgery.

Published: February 2017

Background Sinonasal inverted papilloma (SNIP) is noted for its high rate of recurrence and malignant transformation. Although many clinical studies have demonstrated the effectiveness of the endoscopic approach for SNIP, the surgical strategy has been the subject of much debate. Objective To evaluate the effectiveness of the endoscopic endonasal approach in SNIP. Methods A systematic review of patients with a diagnosis of SNIP and who had surgery at our institution from June 2005 to March 2013 was performed. All the patients who had postoperative follow-up for >2 years were enrolled. Each case was categorized into one of four stages as reported by Krouse. Demographic and tumor date, operative approach, complications, and recurrence rates were collected. Results A total of 125 patients were included in this study. There were 17 patients in stage 1, 40 in stage 2, 57 in stage 3, and 11 in stage 4. The overall recurrence rate was 8.0%. There was no significant difference in recurrence among the stages (all p > 0.05). Recurrence after endoscopic endonasal approach (8.4%) and a combined endoscopic and open exposure procedure (5.6%) were not significantly different (p > 0.05). The recurrence rate was significantly (p < 0.05) higher in patients with revision (15.6%) than in patients in the primary cases (3.8%). A common site of tumor origin was recorded to be from the maxillary sinus (40.2%). Twenty percent of recurrences were observed up to 5 years after surgery. Conclusion Endoscopic surgery may be preferred for treating SNIP. The elevated recurrence rate after revision emphasized the significance of the first surgery. We encourage a follow-up period of at least 5 years.

Published: February 2017

Background The use of bisphosphonates is very common among patients with osteoporosis and multiple myeloma as well as those with bone metastases from various malignancies. The benefits of bisphosphonates are well recognized, but it became evident during the past decade that these medications portend the major adverse effect of osteonecrosis of the jaw, known as bisphosphonate-related osteonecrosis of the jaw. Objective Our aim was to evaluate the specific manifestations of bisphosphonate use on the maxillary sinus in patients with documented bisphosphonate-related osteonecrosis of the jaw. Methods A retrospective review of all the patients diagnosed between October 2003 to August 2014 as having bisphosphonate-related osteonecrosis of the jaw in a large university-affiliated tertiary care medical center. The records of 173 patients diagnosed as having bisphosphonate-related osteonecrosis of the jaw during the study period were retrieved. The available head and neck computed tomographic images were analyzed for cases of involvement of the maxilla. Main Outcome Measures Manifestations of bisphosphonate-related osteonecrosis of the jaw as observed on physical examination and on imaging studies. Results Seventy-one patients (41%) had involvement of the maxilla, 86 patients (49%) had involvement of the mandible, and 16 patients (9%) had involvement of both the maxilla and the mandible. Computerized tomography studies were available for 50 patients with involvement of the maxilla: 36 (72%) had evidence of maxillary sinus opacification (in comparison, the incidence of maxillary sinus opacification as an incidental finding in the general population is reported to be 19%, p < 0.0001). Sixteen patients (32%) had evidence of oroantral fistula, and five patients (10%) had oronasal fistula. Conclusion In addition to its well-established effects on the mandible and maxilla, bisphosphonate-related osteonecrosis of the jaw significantly affected the maxillary sinus. Its radiologic manifestations should be recognized by clinicians and especially by otolaryngologists.

Authors: Huang Zhenxiao , Nayak Jayakar V. , Sun Yan , Huang Qian , Zhou Bing 
Published: February 2017

Background Analysis of recent research indicated that T-helper cells may play an important role in the pathogenesis of chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Objective The purpose of this study was to investigate the peripheral blood Th1 and Th2 cells and eosinophil population in patients with CRS. Methods Peripheral blood samples were obtained from nine nonatopic controls, 37 patients with CRSsNP, and 66 patients with CRSwNP. The samples were then analyzed by flow cytometry analysis (Th1 cell [CD4+, interleukin 4−, interferon γ+]; and Th2 cell [CD4+, interleukin 4+, interferon γ−]). The patients were stratified into four groups based on their allergic status by using skin-prick test results and immunoglobulin E level measurements as the following: (1) nonatopic CRSsNP, (2) nonatopic CRSwNP, (3) atopic CRSsNP, and (4) atopic CRSwNP. Eosinophil counts were also compared. The severity of nasal diseases in these patients was assessed via the Lund-Mackay score. Results No significant differences in peripheral blood Th1 and Th2 cells were found among all the atopic, nonatopic CRS groups, and the nonatopic control groups. Peripheral blood eosinophil levels in atopic CRSwNP were significantly elevated compared with the nonatopic controls (p < 0.05), but no significant difference was found among all atopic and nonatopic CRS groups. Conclusion Analysis of our data demonstrated that a proportion of systemic Th1- and Th2-skewed lymphocytes in all CRS groups were similar to that in healthy subjects, irrespective of atopic status. The patients with CRSwNP and with atopy but not the patients with CRSsNP and with atopy demonstrated systemic eosinophilic inflammation. Further studies are needed to investigate underlying pathophysiologic mechanism or endotypes.
Meaningful use: an electronic medical record tool for cerebrospinal fluid shunt history
Authors: Governale Lance S. , Hoffman Jeffrey M. 
Published: February 2017

The care of patients with shunted hydrocephalus can be complicated. The best assessment is provided when all data are available to the neurosurgery practitioner. However, data can be time-consuming to gather, especially in the setting of a busy practice, a trainee environment with duty-hour restrictions, and an electronic medical record (EMR) not specifically designed for the needs of subspecialists. For these reasons, the complete clinical picture, especially the historical component, is sometimes not assembled.
To address these shortcomings, the authors created a patient-level electronic CSF shunt history tool that leverages the power of the EMR concordant with the United States Centers for Medicare and Medicaid Services meaningful use principles. It is immediately available within the EMR for all users in all patient care contexts (e.g., outpatient, inpatient, perioperative, emergency, and remote access), centrally located, and designed to capture the vast range of circumstances inherent to the hydrocephalus population. Essential shunt data can be rapidly acquired and, as such, may decrease the likelihood of error in diagnosis and/or treatment. The tool also has the potential to aid the practicing neurosurgeon from clinical, quality improvement, and research standpoints. The authors have endeavored to describe this tool in a manner that would allow an interested neurosurgeon to share this publication with health information technology professionals to facilitate the development of a similar tool within their institution's own EMR platform.
Morbidity associated with 30-day surgical site infection following nonshunt pediatric neurosurgery
Authors: Sherrod Brandon A. , Rocque Brandon G. 
Published: February 2017

OBJECTIVE
Morbidity associated with surgical site infection (SSI) following nonshunt pediatric neurosurgical procedures is poorly understood. The purpose of this study was to analyze acute morbidity and mortality associated with SSI after nonshunt pediatric neurosurgery using a nationwide cohort.

METHODS
The authors reviewed data from the American College of Surgeons National Surgical Quality Improvement Program–Pediatric (NSQIP-P) 2012–2014 database, including all neurosurgical procedures performed on pediatric patients. Procedures were categorized by Current Procedural Terminology (CPT) codes. CSF shunts were excluded. Deep and superficial SSIs occurring within 30 days of an index procedure were identified. Deep SSIs included deep wound infections, intracranial abscesses, meningitis, osteomyelitis, and ventriculitis. The following outcomes occurring within 30 days of an index procedure were analyzed, along with postoperative time to complication development: sepsis, wound disruption, length of postoperative stay, readmission, reoperation, and death.

RESULTS
A total of 251 procedures associated with a 30-day SSI were identified (2.7% of 9296 procedures). Superficial SSIs were more common than deep SSIs (57.4% versus 42.6%). Deep SSIs occurred more frequently after epilepsy or intracranial tumor procedures. Superficial SSIs occurred more frequently after skin lesion, spine, Chiari decompression, craniofacial, and myelomeningocele closure procedures. The mean (± SD) postoperative length of stay for patients with any SSI was 9.6 ± 14.8 days (median 4 days). Post-SSI outcomes significantly associated with previous SSI included wound disruption (12.4%), sepsis (15.5%), readmission (36.7%), and reoperation (43.4%) (p < 0.001 for each). Post-SSI sepsis rates (6.3% vs 28.0% for superficial versus deep SSI, respectively; p < 0.001), wound disruption rates (4.9% vs 22.4%, p < 0.001), and reoperation rates (23.6% vs 70.1%, p < 0.001) were significantly greater for patients with deep SSIs. Postoperative length of stay in patients discharged before SSI development was not significantly different for deep versus superficial SSI (4.2 ± 2.7 vs 3.6 ± 2.4 days, p = 0.094). No patient with SSI died within 30 days after surgery.

CONCLUSIONS
Thirty-day SSI is associated with significant 30-day morbidity in pediatric patients undergoing nonshunt neurosurgery. Rates of SSI-associated complications are significantly lower in patients with superficial infection than in those with deep infection. There were no cases of SSI-related mortality within 30 days of the index procedure.

Published: February 2017

OBJECTIVEHemifacial spasm (HFS) is a movement disorder characterized by involuntary spasms of the facial muscles, and it can negatively impact quality of life (QOL). This retrospective study and systematic review with meta-analysis was conducted to investigate the QOL in patients with HFS following intervention with microvascular decompression (MVD) and botulinum toxin (BT).METHODSIn the retrospective analysis, a QOL questionnaire was administered to all patients undergoing MVD performed by a single surgeon. The QOL questionnaire included unique questions developed based on the authors' experience with HFS patients in addition to the health-related QOL HFS-8 questionnaire. The authors also report on a systematic review of the English literature providing outcomes and complications in patients with HFS undergoing treatment with either MVD or BT.RESULTSRegarding the retrospective analysis, 242 of 331 patients completed the questionnaire. The mean score of the 10 QOL questions improved from 22.78 (SD 9.83) to 2.17 (SD 5.75) following MVD (p < 0.001). There was significant improvement across all subscales of the questionnaire between pre- and postoperative responses (p < 0.001). Regarding the systematic review, it is reported that approximately 90% of patients undergoing MVD for HFS experience a complete recovery from symptoms, whereas the mean peak improvement of symptoms following treatment with BT is 77%. Furthermore, patients undergoing MVD reported a greater improvement in the mean supplemental index of QOL as compared with patients receiving BT therapy.CONCLUSIONSMicrovascular decompression offers a significant improvement in QOL in well-selected patients suffering from HFS, and may offer an increased benefit for QOL over BT injections.
