Published: June 2017

ABSTRACT

Background
This study aims to evaluate dental emergency visits in a public hospital as the number of dental emergency visits has recently increased.

Materials and methods
This was a retrospective observational study. This study was approved by the local ethical committee and data were recorded from the dental emergency service record book between January 1, 2012, and December 31, 2013.

Results
In total, 1,477 (4.01%) patients were admitted to emergency dentist services. Mean age was 24.59 ± 11.07 (min–max: 2–76) and 978 (66.2%) patients were between 19 and 35 years old. The most common diagnosis was pulpitis or periapical abscess (n = 1033, 69.9%) and the most common practice was the prescription of antibiotics and/or analgesics (n = 885, 59.9%).

Conclusion
The latest increase in the number of dental emergency visits is a burden, and emergency physicians must be capable of differentiating the real emergencies from common uncomplicated complaints.

Published: June 2017

ABSTRACT
Dens invaginatus is a dental anomaly caused by an invagination of enamel that affects in most of the cases the crown of the tooth. The treatment depends on the degree of invagination and morphological involvement. This report describes a dental anomaly affecting the permanent lower lateral incisor of a 13-year-old patient, which resulted in swelling, pain, and dental impaction. The initial radiographic examination suggested a gemination, a fusion with a supernumerary tooth or a dens invaginatus extending to the root. For more accurate diagnosis and treatment plan of this anomaly, computed tomography scan was performed, which revealed the presence of enamel in the root. Due to pain and the impossibility of performing an orthodontic traction, the treatment of choice in this case was dental extraction. The final diagnosis was confirmed by histopathological examination and revealed the rare occurrence of a radicular dens invaginatus.

Published: June 2017

Introduction The role of proximal femur morphology to the development of certain proximal femur fracture types both femoral neck and trochanteric fractures has been observed. However, the relavance of acetabular morphology to the development of proximal femur fractures is not extensively questioned. Therefore the aim of the study was to determine whether there is a correlation between acetabular morphology and pathogenesis of 2 different hip fracture types after low energy trauma. Methods This retrospective study includes 60 cases (41 women, 19 men) with a proximal femoral fracture after a low energy trauma between July 2012 and December 2014. Acetabular depth and acetabular index were measured on pelvic radiographs. Neck shaft angle, hip axis length and cortical index were measured on pelvic computed tomography scans. All measurements were performed on the contralateral hip. Results Mean age was 77.56 ± 8.99 years (range 61-92 years). No statistically significant difference was found with regard to neck shaft angle, acetabular depth or cortical index measurements between patients with femoral neck fracture and patients with trochanteric femoral fractures (p>0.05). Acetabular index measurement was higher (p = 0.001) and hip axis length measurement was lower (p = 0.001) in trochanteric fracture group as compared to femoral neck fracture. Conclusions The rate of trochanteric femur fractures is higher in patients with high acetabular index, whereas the rate of femoral neck fractures is higher in patients with increased hip axis length.

Published: June 2017

Background A high rate of postoperative dislocation in total hip arthroplasty (THA) for Crowe IV developmental dysplasia of the hip (DDH) has been reported, 1 of the main reasons being higher true acetabular anteversion. If the cup is fixed with normal anteversion, the anterior rim will be excessively exposed, which reduces the contact areas of the cup and bone, affects prosthesis stability, and leads to iliopsoas tendinitis and persistent hip pain after THA. The aim of this study was to demonstrate that when cup anteversion is larger, adjusting femoral anteversion to bring the combined anteversion (CA) into the “safe zone” might prevent dislocation. Methods After having fixed the cup in the acetabulum according to the patients’ native acetabular anteversion, we shortened and rotated the proximal femur to reduce femoral anteversion, adjusting the CA into the “safe zone”. The Harris Hip Score (HHS) was used to evaluate hip joint function. Computerised tomography scanning was used to measure the anteversion angles. Results All patients were followed up without any dislocation. Preoperative and 12 months after surgery, the mean HHS were 43.3 ± 2.6 (38-47) and 88.1 ± 3.3 (78-92) respectively. Pre- and post-operation, the mean CA angles were 88.6° ± 9.4° (80.3°-119.4°) and 49.2° ± 2.6° (43.4°-54.4°) respectively. The bone healing time of femoral osteotomy ranged from 4 to 14 months, with a mean time of 7.5 months. Conclusions This CA technique in THA for Crowe IV DDH can effectively prevent postoperative dislocation and provide good hip function.

Introduction During the posterior approach to the hip, the short external rotators are detached and secured with stay sutures. At the time of definitive closure, some surgeons incorporate the initial sutures into their repair while others discard for fresh sutures, presumably as an infection prevention measure. We have conducted a pilot study to investigate whether the incorporation of the primary stay sutures may constitute an infection risk to the patient undergoing a total hip replacement through the posterior approach. Materials and methods The pilot study was conducted between August 2014 and June 2015. A pair of suture specimens were sent from 25 patients to microbiology, 1 set of primary stay sutures and 1 set of control sutures. All operations were carried out by the senior author through a posterior approach. Results All specimens were analysed for bacterial and fungal growth, using extended cultures. 1 set of primary sutures had a positive growth, likely from skin contamination; 1 set of control sutures also had a positive growth, likely from environmental contamination. Conclusions Our pilot study suggests that the practice of incorporating the primary stay sutures for definitive soft tissue repair of the short external rotators, rather than exchanging them for new sutures, can be deemed safe.

Background: Patient satisfaction, as measured by Press Ganey (PG) surveys, partially determines reimbursement rates. Knowing what influences these scores can lead to higher reimbursement for total hip arthroplasty (THA) surgeons. Currently, it is unknown whether gender biases exist in satisfaction surveys post-THA. Therefore, we asked: (i) which PG survey factors most influence hospital ratings among men and women after THA; and (ii) is there a difference in survey element responses and overall hospital ratings between men and women post-THA? Methods: We queried the PG database for patients who underwent THA from November 2009 to January 2015, which yielded 692 patients (277 men, 415 women). Weighted means were analysed for the scores of PG domains between men and women. A multiple regression analysis was performed for each gender, with overall hospital satisfaction as the dependent variable, in order to assess the influence (β-weight) of each PG domain. Results: For men, pain management (β = 0.317, p = 0.021) most influenced overall hospital rating. For women, staff responsiveness (β = 0.451, p<0.001) most influenced overall hospital rating. This was followed by communication with nurses (β = 0.373, p<0.001), and doctors (β = 0.236, p = 0.002). There were no significant differences in mean overall hospital rating between groups. Conclusions: It is advantageous for orthopaedic surgeons to focus on the PG domains most pertinent to each patient gender post-THA. Focusing efforts based on gender may allow for better patient satisfaction, optimised reimbursements, and improved hospital ratings.

Victims and restorative justice: experiences of (non)participants
This article describes some victim-related research results of both an action research into the Flemish practice of conferencing, as well as the results of a European comparative research on victim-offender mediation. Through these results, we examine what victims think of restorative justice and why they choose (not) to participate. This way, we aim to fill a certain gap in restorative justice literature especially when it comes to non-participating victims (Van Camp & Wemmers, 2016), a group which remains hard to interview.

Published: June 2017

According Sebire, Standage and Vansteenkiste (2008), goals contents (motives) are the major drivers of behavior, giving rise to the goal content theory, which is in the basis of Goal Content for Exercise Questionnaire (GCEQ: Sebire et al., 2008) development. So, the main goal of present study was to conduct the validation of GCEQ for a sample of Portuguese elderly (n = 311), with equal or higher ages than 60 years old (M = 68.53; DP = 6.69). The main results show us that CGEQ measurement model (5 factors, 20 items) only present adequate fit to data after the elimination of 3 items: S-Bχ²=219.9, df=109, p=.001, SRMR=.049, TLI=.916, CFI=.934, RMSEA=.057, RMSEA 90% CI=.046-.068, PCFI=.747). Besides that, the 5 factors show us acceptable values of composite reliability: between .76 and .88. Those findings allow us to conclude that GCEQ with 5 factors and 17 items can be used to measure goal content in a population of elderly Portuguese people in physical activity domain.

Published: June 2017

AbstractThe development of new tuning methods for π‐conjugated insulated molecular wires with strictly defined axle lengths as well as positions and degrees of macrocycle coverage would provide unprecedented insight into insulation effects in functionalized materials. Herein, iterative reactions of oligo(phenylene ethynylene) (OPE) linked with permethylated α‐cyclodextrins were carried out to fabricate insulated molecular wires with a defined length and insulation in desired areas. Insulated OPEs were elongated in a stepwise manner by performing sequential coupling/deprotection reactions. The insulated areas on the OPE units in each expansion step were selectively controlled by means of programmed solvent conditions (high/low polarity). Moreover, a completely insulated OPE (up to a linked [11]rotaxane) with high structural regularity and high covering ratio was synthesized by appropriate tuning of the Pd catalyst and an extension unit bearing a traceless capping unit based on a tert‐butyldimethylsilyl group. This strategy may guide the development of the selective synthesis of fully insulated, partially insulated, and uninsulated molecular wires with well‐defined lengths and covered/uncovered areas.

AbstractMid‐infrared (MIR, 2–20 μm) second‐order nonlinear optical (NLO) materials with outstanding performances are of great importance in laser science and technology. However, the enormous challenge to design and synthesize an excellent MIR NLO material lies in achieving simultaneously a strong second harmonic generation (SHG) response [dij >0.6 × AgGaS2 (AGS)] and wide band gap (Eg>3.5 eV). Herein three new MIR NLO materials, AZn4Ga5S12 (A=K, Rb, Cs) are reported, which crystallize in the KCd4Ga5S12‐type structure and adopt a 3D diamond‐like framework (DLF) consisting of MS4 (M=Zn/Ga) tetrahedra; achieving the desired balance with strong powder SHG response (1.2–1.4 × AGS) and wide band gap (Eg≈3.65 eV). Moreover, they also show large laser induced damage thresholds (LIDTs, 36 × AGS), a wide range of optical transparency (0.4–25 μm) and ultrahigh thermal stability (up to 1400 K). Upon analyzing the structure‐property relationship of AXII4XIII5Q12 family, these 3D DLF structures can be used as a highly versatile and tunable platform for designing excellent MIR NLO materials.
Grade efficiency for sieve classification processes
Authors: Hennig Manuel , Teipel Ulrich 
Published: June 2017

AbstractModelling of the screening performance for classification processes is important to obtain a first estimate for a new process in the planning phase. In this work especially the grade efficiency curves of sieve classifications with vibrating screens were examined. A sensitivity study was performed by changing the operating parameters of the sieving machine and the parameters of the charging material (i.e. mass flow, particle size, etc.). The aim was to correlate the input parameters with the grade efficiency curve of the classification process. The main aspect of the presented work is to find an appropriate method to adjust four screening parameters in a way that the measured grade efficiency curve is modelled correctly. Several methods for this adjustment step are reviewed. A sensitivity study using a tumbling screen was performed previously. It is apparent that for that study, different methods and models for the parameter adjustment need to be used. Furthermore it is shown that data reconciliation is necessary, since the mass balance of the particle streams may not be closed correctly. In summary this work is the first step to predict the screening performance of a sieving machine without material‐ and time‐consuming experiments.
Neural organization of afferent pathways from the stomatopod compound eye
Authors: Thoen Hanne H. , Strausfeld Nicholas J. , Marshall Justin 
Published: June 2017

AbstractCrustaceans and insects share many similarities of brain organization suggesting that their common ancestor possessed some components of those shared features. Stomatopods (mantis shrimps) are basal eumalacostracan crustaceans famous for their elaborate visual system, the most complex of which possesses 12 types of color photoreceptors and the ability to detect both linearly and circularly polarized light. Here, using a palette of histological methods we describe neurons and their neuropils most immediately associated with the stomatopod retina. We first provide a general overview of the major neuropil structures in the eyestalks lateral protocerebrum, with respect to the optical pathways originating from the six rows of specialized ommatidia in the stomatopod's eye, termed the midband. We then focus on the structure and neuronal types of the lamina, the first optic neuropil in the stomatopod visual system. Using Golgi impregnations to resolve single neurons we identify cells in different parts of the lamina corresponding to the three different regions of the stomatopod eye (midband and the upper and lower eye halves). While the optic cartridges relating to the spectral and polarization sensitive midband ommatidia show some specializations not found in the lamina serving the upper and lower eye halves, the general morphology of the midband lamina reflects cell types elsewhere in the lamina and cell types described for other species of Eumalacostraca.

AbstractNeurons expressing nitric oxide (NO) synthase (nNOS) and thus capable of synthesizing NO play major roles in many aspects of brain function. While the heterogeneity of nNOS‐expressing neurons has been studied in various brain regions, their phenotype in the hypothalamus remains largely unknown. Here we examined the distribution of cells expressing nNOS in the postnatal and adult female mouse hypothalamus using immunohistochemistry. In both adults and neonates, nNOS was largely restricted to regions of the hypothalamus involved in the control of bodily functions, such as energy balance and reproduction. Labeled cells were found in the paraventricular, ventromedial, and dorsomedial nuclei as well as in the lateral area of the hypothalamus. Intriguingly, nNOS was seen only after the second week of life in the arcuate nucleus of the hypothalamus (ARH). The most dense and heavily labeled population of cells was found in the organum vasculosum laminae terminalis (OV) and the median preoptic nucleus (MEPO), where most of the somata of the neuroendocrine neurons releasing GnRH and controlling reproduction are located. A great proportion of nNOS‐immunoreactive neurons in the OV/MEPO and ARH were seen to express estrogen receptor (ER) α. Notably, almost all ERα‐immunoreactive cells of the OV/MEPO also expressed nNOS. Moreover, the use of EYFPVglut2, EYFPVgat, and GFPGad67 transgenic mouse lines revealed that, like GnRH neurons, most hypothalamic nNOS neurons have a glutamatergic phenotype, except for nNOS neurons of the ARH, which are GABAergic. Altogether, these observations are consistent with the proposed role of nNOS neurons in physiological processes.
Chirality Induction from a Chiral Guest to the Hydrogen‐Bonding Network of Its Hexameric Resorcinarene Host Capsule

Published: June 2017

AbstractThe hexameric capsule of resorcin[4]arene 1 is capable of encapsulating tertiary amines, which has recently been used in the application of [(1)6(H2O)8] as (co‐)catalyst in various asymmetric reactions. However, not much is known about the highly asymmetric but conformationally very dynamic structure of the capsule after uptake of chiral molecules. Therefore, in this contribution, we utilize electronic circular dichroism and vibrational circular dichroism spectroscopy to investigate how several chiral guest molecules affect the structural preferences of the capsule [(1)6(H2O)8]. In particular, we show that one small chiral amine encapsulated in [(1)6(H2O)8] is sufficient to control and dictate the stereochemical preferences of the entire capsule. Furthermore, neither strong π–π interactions nor a significant steric bulk are required for this induction. The observation of such a chiral imprint of the guest's stereochemistry onto its host molecule is expected to have implications also for other supramolecular capsules.
