Disc Displacement with Intermittent Lock: A Case Series of a Rarely-addressed Disorder

Aim: We describe a series of five cases presented with disc displacement with reduction and intermittent lock (DDwRIL), from presentation to follow-up. Background: Disc displacement with reduction with intermittent lock is a temporomandibular disorder in which the disc is displaced and reduced, along with temporary locking leading to limited opening. Due to the fact that it has only been recognized as a separate disease in 2013, there is no clear guideline on the management of these cases. Cases descriptions: We present five cases of clinically established DDwRIL in different age groups. We walk through clinical presentation and diagnostic workup. Several modalities were used in the management of described cases from noninterventional management with counselling only to physical and splint therapies. Conclusion: Disc displacement with reduction, with intermittent locking is a challenging temporomandibular disorder with risk to progress into disc displacement without reduction and hence necessitates a tailored approach and long-term follow-up. Clinical significance: To our knowledge, this is the first case series reported on DDwRIL which provides detailed clinical presentation, examination, management, and discussion for orofacial pain practitioners as well as for future studies on this disease

A Proposal of Standardised Data Model for Cloud Manufacturing Collaborative Networks

[EN] The growing amount of data to be handled by collaborative networks raises the need of introducing innovative solutions to fulfil the lack of affordable tools, especially for Small and Medium-Sized Enterprises, to manage and exchange data. The European H2020 Project Cloud Collaborative Manufacturing Networks develops and offers a structured data model, called Standardised Tables, as an organised framework to jointly work with existing databases to manage big data collected from different industries belonging to the CNs. The information of the Standardised Tables will be mainly used with optimisation and collaboration purposes. The paper describes an application of the Standardised Tables in one of the pilots of the aforementioned project, the automotive industry pilot, for solving the collaborative problem of a Materials Requirement Plan.The research leading to these results is in the frame of the “Cloud Collaborative Manufacturing Networks” (C2NET) project, which has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 636909.Andres, B.; Sanchis, R.; Poler, R.; Saari, L.

In vitro germination and growth of Argania spinosa of Beni Snassen (Eastern Morocco) at various concentrations of NaCl

Le présent travail se propose d’étudier l’effet du sel (chlorure de sodium) sur la germination et la croissance de l’arganier in vitro en testant différentes concentrations. L’étude a été réalisée dans une chambre de culture à température et à photopériode contrôlées. Les amandes sont mises à germer dans des tubes à essais sur un milieu gélosé (Agar + eau). Aucune différence significative de la germination des amandes entre le témoin et les essais en présence de 1g /l, 3 g/l et 5 g/l de NaCl. Au delà de 5 g/l, une différence significative a été révélée entre le témoin et les amandes à 7 g/l et 9 g/l de NaCl. L’émergence de l’axe de la tige suit la même évolution. En ce qui concerne la croissance, les mesures de la longueur de la racine principale et de l’axe de la tige montrent une différence significative pour les différentes concentrations. L’analyse statistique à 5% montre qu’il y a un effet du sel sur la production des biomasses aérienne et racinaire. Mots clés : Germination - Croissance - NaCl - Arganier - Beni-Snassen - MarocThe present work intends to study, salt effect (sodium chloride) on in vitro germination and growth of Argania spinosa. The test was conducted in a grouth chamber where temperature and photoperiod were controlled. Seeds were put to germinate in tubes test with a gelose middle (Agar + water). Six concentrations of NaCl were tested. Results showed that there is not significant difference of germination between the witness and NaCl concentrations of 1 g/l, 3 g/l and 5 g/l. A significant difference has been found between the witness and the germination of almonds to concentrations of NaCl to 7 g/l and 9 g/l. The emergence of the stem axis follows the same evolution. With regard to the growth, measures of lengths of the main root and the stem axis showed a significant difference for the all concentrations tested. The statistical analysis to 5% showed that there is a significant effect of salt on the production of the aerial and root biomass.

Supporting Smart Home Scenarios Using OWL and SWRL Rules

Despite the pervasiveness of IoT domotic devices in the home automation landscape, their potential is still quite under-exploited due to the high heterogeneity and the scarce expressivity of the most commonly adopted scenario programming paradigms. The aim of this study is to show that Semantic Web technologies constitute a viable solution to tackle not only the interoperability issues, but also the overall programming complexity of modern IoT home automation scenarios. For this purpose, we developed a knowledge-based home automation system in which scenarios are the result of logical inferences over the IoT sensors data combined with formalised knowledge. In particular, we describe how the SWRL language can be employed to overcome the limitations of the well-known trigger-action paradigm. Through various experiments in three distinct scenarios, we demonstrated the feasibility of the proposed approach and its applicability in a standardised and validated context such as SARE

Prevalence of oral behaviours in general dental patients attending a university clinic in Italy

Background: Oral behaviors represent a diverse array of habits beyond the physiological behaviors of the stomatognathic system. Objective: To describe the prevalence of different oral behaviors, as reported with the Oral Behavior Checklist (OBC-21), in a convenience sample of patients attending an Italian university clinic for routine dental cares. Methods: In this study, charts of adult patients presenting to the dental department of a regional hospital in Trieste, Italy, from January 2018 and January 2019 were reviewed. Patients with complete files were retrieved, and those with orofacial pain complaints were excluded. OBC-21 scores and grades (score of 0 corresponding to no risk, 1-24 to low risk, and higher than 24 to high risk) were analyzed and stratified according to age and sex. Results: Data from a total of 1424 patients were reported. The overall mean OBC score was 13.3 ± 9.9, with 6.7% no-risk grade, 79.6% low-risk grade, and 13.7% high-risk grade. In general, mean OBC scores decreased with increasing age. Females showed a higher frequency of high-risk grade than males. Most frequent prevalent habits included yawning (73.1%), eating between meals (66.9%) and chewing food on one side only (63.3%). Other behaviors were also highly prevalent, including pressing, touching, or holding teeth together other than while eating (52.7%) and awake clenching (47.5%). Conclusion: A low-risk grade of oral behaviors has been found to be frequent in our sample. Future studies are warranted to confirm these findings in larger, representative general populations and to assess if any of these habits are linked to negative effects on the stomatognathic system

Incidence of post-operative pain following a single-visit pulpectomy in primary molars employing adaptive, rotary, and manual instrumentation: a randomized clinical trial

Background and Objectives. To differentiate the intensity of postoperative pain after primary molar pulpectomy employing manual instrumentation versus two single-file systems with different kinetics (the XP-Endo shaper file with adaptive instrumentation vs. the Kedo-SG blue file with continuous rotation instrumentation). Materials and Methods. This three-arm, single-blind, randomized clinical trial included assessing 75 healthy children between 4 to 9 years who required pulpectomy for primary molars (mandibular first and second). The three groups each had an equal number of children. Children in Group 1 had their teeth instrumented with the XP-endo Shaper, children in Group 2 had their teeth instrumented with the Kedo-SG Blue file, and children in Group 3 had their teeth instrumented manually using K-files. The degree of postoperative pain was measured using a four-point pain scale at 6-, 12-, 24-, 48-, and 72-h following therapy. Each participant’s parent received five flashcards with four faces and a word characterizing each face. The data were analyzed using Kruskal–Wallis and chi-square tests. The level of significance was set to 5%. Results. During the follow-up period, there was a significant difference in postoperative pain intensity between the three groups. The XP-endo shaper was associated with considerably decreased post operative at the 6- and 12-h interval followed by Kedo-SG. The highest post-operative discomfort across the groups was related to the patients who underwent manual instrumentation. Conclusion. In comparison to rotary and manual instrumentation, postoperative pain severity was reduced with adaptive instrumentation

Development of a scale to measure stigma related to podoconiosis in Southern Ethiopia

Background: Health-related stigma adds to the physical and economic burdens experienced by people suffering from neglected tropical diseases (NTDs). Previous research into the NTD podoconiosis showed significant stigma towards those with the disease, yet no formal instrument exists by which to assess stigma or interventions to reduce stigma. We aimed to develop, pilot and validate scales to measure the extent of stigma towards podoconiosis among patients and in podoconiosis-endemic communities. Methods: Indicators of stigma were drawn from existing qualitative podoconiosis research and a literature review on measuring leprosy stigma. These were then formulated into items for questioning and evaluated through a Delphi process in which irrelevant items were discounted. The final items formed four scales measuring two distinct forms of stigma (felt stigma and enacted stigma) for those with podoconiosis and those without the disease. The scales were formatted as two questionnaires, one for podoconiosis patients and one for unaffected community members. 150 podoconiosis patients and 500 unaffected community members from Wolaita zone, Southern Ethiopia were selected through multistage random sampling to complete the questionnaires which were interview-administered. The scales were evaluated through reliability assessment, content and construct validity analysis of the items, factor analysis and internal consistency analysis. Results: All scales had Cronbach’s alpha over 0.7, indicating good consistency. The content and construct validity of the scales were satisfactory with modest correlation between items. There was significant correlation between the felt and enacted stigma scales among patients (Spearman’s r = 0.892; p < 0.001) and within the community (Spearman’s r = 0.794; p < 0.001). Conclusion: We report the development and testing of the first standardised measures of podoconiosis stigma. Although further research is needed to validate the scales in other contexts, we anticipate they will be useful in situational analysis and in designing, monitoring and evaluating interventions. The scales will enable an evidencebased approach to mitigating stigma which will enable implementation of more effective disease control and help break the cycle of poverty and NTDs

Factors related to discontinued clinic attendance by patients with podoconiosis in southern Ethiopia: a qualitative study

Background Podoconiosis is a lymphoedema of non-infectious cause which results in long-term ill health in affected individuals. Simple, effective treatment is available in certain parts of Ethiopia, but evidence indicates that not all patients continue collecting treatment supplies from clinic sites once started. We used qualitative techniques to explore factors related to discontinued attendance at outreach clinics of a non-government organization in southern Ethiopia. Methods A cross-sectional qualitative study was conducted in four clinic sites through unstructured in-depth interviews, key informant interviews and focus group discussions with the involvement of 88 study subjects. Results Discontinuation of clinic visits is common among podoconiosis patients. The reasons were: remoteness from the clinic sites, unrealistic expectation of ‘special’ aid, worry about increasing stigma, illness and misconceptions about treatment. Conclusions Several of these factors are remediable through community and individual information and education. Appropriate routes to deliver this information must be identified. Certain factors (such as distance to clinic sites and stigma) require substantial expansion of services or liaison with village-level government health services
