Immunological Profile of Periapical and Periodontal Lesions: Current Concepts in the Role of T Cells
Authors: Arun KV , Nainar Deepavalli Arumuga , Alamelu Swarna 
Published: July 2019

ABSTRACT
Periapical lesions of endodontic origin and periodontitis are the two common chronic conditions that constitute the immunoinflammatory responses to putative oral pathogens. Both the conditions encompass similar patterns of development and pathologic mechanisms of host-mediated tissue destruction and subsequent establishment of the lesion. This host inflammatory response is attributed to a large array of immune cells that play a regulatory role in the protective and destructive pathways culminating in these two diseases. Hence, knowledge of the host response involved in their pathogenesis is essential to comprehend the disease process and thus aid in establishing proper therapeutic strategies to keep the host response under control. This review will focus on the pivotal role played by the T cells and its various subsets, namely the T helper (Th)1, Th2, Th17, Treg, Th22, and Th9, and elicit deeper insights on the Th1/Th2 and the Th17/Treg paradigm.

Invasive Cervical Resorption: A Clinical Case Report demonstrating the Value of CBCT in Diagnosis and Treatment Planning
Authors: Canakapalli Venkat 
Published: July 2019

ABSTRACT
Invasive cervical resorption (ICR) is a common clinical entity. Invasive cervical resorption can be arrested using the “Heithersay approach” (i.e., mechanical debridement, treatment with TCA, and restoration). Prudent case selection and proper execution can lead to the successful treatment and long-term retention of the tooth. The key aspects are the location, size, and accessibility of the lesion and the structural integrity of the tooth. Cone beam computed tomography imaging is an invaluable tool to assess and treat ICR.

Comparison of Implantation Rates in Ultrasound-guided vs Clinical Touch Embryo Transfer
Authors: Jindal Manvi , Swarankar ML 
Published: July 2019

ABSTRACT

Aims
The present study was conducted in the fertility unit of a medical college to compare the implantation rate of embryo in ultrasound-guided vs clinical touch method of embryo transfer. Today, approximately 80% of women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) will reach the embryo transfer stage with good quality embryos. Traditionally, the ‘clinical touch’ method has been used to guide placement of the embryo transfer. The use of ultrasound to guide embryo transfer would allow accurate and atraumatic positioning of the catheter tip near the uterine fundus.

Materials and methods
A prospective study was conducted at fertility center of Mahatma Gandhi Hospital. A total 100 patients requiring IVF, from a period of July 2011—July 2013 were taken into the study. A total of 50 patients were subjected to USG-guided embryo transfer and 50 patients were subjected to clinical touch embryo transfer. Detailed patient history, clinical examination, relevant investigation and details of procedure were entered in a prestructured proforma. The data were entered and analyzed in Microsoft Office Excel.

Results
There was a significant improvement in the implantation rates in the USG-guided group (31.9%) as compared to clinical touch group (24.3%). There was also a significant improvement in the pregnancy rates in the USG-guided group (40%) as compared to the clinical touch group (28%). Compared with the traditional clinical touch method, the abdominal ultrasound-guided embryo transfer was found to have a number of advantages.

Authors: Kaur Avneet , Chhonkar Devendra Pal Singh , Sarawgi Aditi 
Published: July 2019

ABSTRACT
The neutral zone technique is an alternative approach for the construction of the complete dentures. It is most effective for cases where there is a highly atrophic ridge. The technique aims to construct a denture, i.e., shaped by muscle function and is in harmony with the surrounding oral structures. This clinical report describes the fabrication of complete dentures for a patient with poorly formed mandibular ridges.

Palatoradicular Groove Associated Defect Resolved with GIC, Alloplastic Graft and GTR Membrane
Authors: Mishra Pulak , Godara Sonia , Kapoor Radhika 
Published: July 2019

ABSTRACT
The region of maxillary lateral incisor is an area of embryological importance with major and minor malformations like, gemination, fusion, cysts, dens in dente, peg-shaped laterals, talon cusps, supernumerary roots, and palatogingival groove (PGG). Palatogingival groove is a developmental groove usually found on the lingual aspect of maxillary incisors. It can be simple or complex on the basis of its connection to the pulp. These grooves act as a nidus for plaque accumulation which destroys the sulcular epithelium and later deeper parts of the periodontium. Since proper cleaning of this region is difficult by patient himself, it can lead to serious localized periodontal lesion or can communicate with endodontic lesion. Suggested treatment modalities are curettage of the affected tissues, elimination of the groove by grinding (saucerization), or by sealing with a variety of filling materials. If the groove extends beyond the middle-third of the root apex, surgical procedures are required, including use of barriers and intraosseous alloplastic graft to correct the defect.

Premenstrual Syndrome: Correlation and Functional Impairment
Authors: Swami Murlidhar , Narain Mona , Kanwal Krishna 
Published: July 2019

ABSTRACT

Introduction
Premenstrual syndrome (PMS) and its more severe form “premenstrual dysphoric disorder (PMDD)” is a common yet underdiagnosed disorder. It is characterized by anxiety, mood changes, and several somatic symptoms in the last week of the luteal phase and began to remit within a few days after the onset of the follicular phase.

Aims
The aim of this study was to evaluate the prevalence of PMS and PMDD among females at a tertiary care center and evaluate the associated symptomatology, sociodemographic variables, and functional impairment.

Materials and methods
In an observational, cross-sectional study, 150 randomly selected females (18–30 years) were evaluated for menstrual history after sociodemographic profiling. Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV)-TR (SCID)-PMDD was applied among those who were positive on premenstrual symptoms screening tool. Statistical analysis was done using Statistical Package for the Social Sciences, version 14.0.

Results
The prevalence of PMS was 21.33%. Moderate to severe PMS was 14% and PMDD was 7.33% according to DSM-IV-TR criteria. Fatigue/lack of energy, decreased interest in work were the most commonly reported symptoms. Decreased school/work efficiency and productivity was the commonest form of functional impairment. Increased body mass index, onset of symptoms since menarche, duration of premenstrual symptoms, menstrual cramps, and family history showed statistically significant association with PMS/PMDD.

Conclusion
Premenstrual syndrome is fairly common and causes significant functional impairment. Screening females in relevant age group for its symptomatology may aid in early detection and better management.

A Variant Articular Facet on Left Second Rib
Authors: Mehra Simmi 
Published: July 2019

ABSTRACT
During routine scanning of bones in the Department of Anatomy, Mahatma Gandhi Medical College & Hospital, Jaipur, India, an unusual second rib belonging to left side was found having an oval facet, almost centrally placed along the inner border of the shaft. In the absence of the corresponding skeleton, it can be hypothesized that the left first rib or an extra rib articulated with the second rib at this facet. Such structural anomalies of ribs are quite rare and need to be documented. If present, they may lead to compression of neurovascular structures crossing the ribs leading to thoracic outlet syndrome. An incidence of 0.3% of synostosis of first and second ribs has been reported in the literature. Search of literature reveals that there are 22 known syndromes in which fused ribs are a constant component. Such a variant second rib as found in the present case could lead to neurovascular compression and a possible indicator of underlying systemic disorder.

Surgical Management of Chronic Bilateral Condylar Dislocation
Authors: Sharma Sunil , Chitlangia Punit , Sharma Dinesh C ,   Amit 
Published: July 2019

ABSTRACT
Dislocation is the complete separation of the articular surfaces of a joint and fixation in an abnormal position. In case of mandibular dislocation, the normal anatomic relationship of the mandibular condyle with the glenoid fossa disrupts and condyle seats in an unfavorable position which is mostly anterior. Dislocation can be of acute and chronic subtypes. Acute dislocation is once in a lifetime event, but chronic dislocations are painful and distressing to the patient. There are various nonsurgical and surgical treatment options available in the literature but the most sought after method is eminectomy. A case of chronic dislocation treated surgically with eminectomy is reported here.

Euthanasie en psychisch lijden
Authors: Lemmens Willem 
Published: July 2019

Abstract

Euthanasia and psychological suffering: empathy beyond any taboo?

Nowadays, when facing the death wish of a patient, a psychiatrist in Belgium or the Netherlands may legally initiate euthanasia. Proponents of this situation argue that a psychiatric patient’s autonomy and the seriousness of his or her suffering ought to be acknowledged and taken fully seriously. A psychiatrist’s consent to euthanasia will here have to be grounded on an assessment of psychological suffering that cannot be purely medical in character, which in turn will have to depend, for a good deal, on empathy. However, a closer look at such empathy uncovers various paradoxes and leads to the conclusion that a psychiatrist with the kind of empathy that is appropriate to his or her role, i.e., ‘cognitive’ empathy, will resist rather than go along with the patient’s death wish.
CALIOPE-Urban v1.0: coupling R-LINE with a mesoscale air quality modelling system for urban air quality forecasts over Barcelona city (Spain)
Authors: Benavides Jaime , Snyder Michelle , Guevara Marc , Soret Albert , Pérez García-Pando Carlos , Amato Fulvio , Querol Xavier , Jorba Oriol 
Published: July 2019

Abstract. The NO2 annual air quality limit value is systematically exceeded in many European cities. In this context, understanding human exposure, improving policy and planning, and providing forecasts requires the development of accurate air quality models at the urban (street level) scale. We describe CALIOPE-Urban, a system coupling CALIOPE – an operational mesoscale air quality forecast system based on the HERMES (emissions), WRF (meteorology) and CMAQ (chemistry) models – with the urban roadway dispersion model R-LINE. Our developments have focused on Barcelona city (Spain), but the methodology may be replicated for other cities in the future. WRF drives pollutant dispersion and CMAQ provides background concentrations to R-LINE. Key features of our system include the adaptation of R-LINE to street canyons, the use of a new methodology that considers upwind grid cells in CMAQ to avoid double counting traffic emissions, a new method to estimate local surface roughness within street canyons, and a vertical mixing parameterisation that considers urban geometry and atmospheric stability to calculate surface level background concentrations. We show that the latter is critical to correct the night-time overestimations in our system. Both CALIOPE and CALIOPE-Urban are evaluated using two sets of observations. The temporal variability is evaluated against measurements from five traffic sites and one urban background site for April–May 2013. While both systems show a fairly good agreement at the urban background site, CALIOPE-Urban shows a better agreement at traffic sites. The spatial variability is evaluated using 182 passive dosimeters that were distributed across Barcelona during 2 weeks for February–March 2017. In this case, the coupled system also shows a more realistic distribution than the mesoscale system, which systematically underpredicts NO2 close to traffic emission sources. Overall CALIOPE-Urban improves mesoscale model results, demonstrating that the combination of both scales provides a more realistic representation of NO2 spatio-temporal variability in Barcelona.
Geology of the Abitibi Greenstone Belt
Authors: Monecke Thomas , Mercier-Langevin Patrick , Dubé Benoît , Frieman Ben M. 
Published: July 2019

Abstract
The Abitibi greenstone belt, which straddles the border between Ontario and Quebec in eastern Canada, represents one of the largest and best-preserved Neoarchean greenstone belts in the world. The belt consists of E-trending successions of folded volcanic and sedimentary rocks and intervening domes of intrusive rocks. Submarine volcanism occurred between 2795 and 2695 Ma. Six volcanic assemblages have been defined, recording submarine volcanism during specific periods of time. Komatiite successions within some of these volcanic assemblages are host to magmatic sulfide deposits. However, economically more important are volcanogenic massive sulfide (VMS) deposits, which contain a total of ~775 million tonnes (t) of polymetallic massive sulfides. Approximately half of the endowment is hosted by volcanic rocks of the 2704 to 2695 Ma Blake River assemblage. VMS deposits of this assemblage also account for most of the synvolcanic gold in the Abitibi greenstone belt, totaling over 1,100 t (~35 Moz).
Submarine volcanism was followed by the deposition of large amounts of sedimentary material derived from a shallow marine or subaerial hinterland, created as a result of crustal thickening during an early phase of mountain building at ≤2690 to ≤2685 Ma. Submarine volcanic rocks and the overlying flysch-like sedimentary rocks of the Porcupine assemblage were affected by large-scale folding and thrusting during at least one deformational event prior to 2679 Ma. At this time, a terrestrial unconformity surface developed between the older and already deformed rocks of the Abitibi greenstone belt and molasse-like sedimentary rocks of the Timiskaming assemblage, which were deposited between ≤2679 and ≤2669 Ma. Deposition of the Timiskaming sedimentary rocks occurred in extensional basins and was locally accompanied by predominantly alkaline volcanism and related intrusive activity.
Crustal shortening and thick-skinned deformation resulted in the structural burial of the molasse-like sedimentary rocks of the Timiskaming assemblage after 2669 Ma. Panels of Timiskaming deposits were preserved in the footwall of these thrusts, which are today represented by major fault zones cutting across the supracrustal rocks of the Abitibi greenstone belt. The structural history of these fault zones is complicated by late-stage strike-slip deformation. The Porcupine-Destor and Larder Lake-Cadillac fault zones of the southern Abitibi greenstone belt as well as second- and third-order splays off these fault zones are host to a number of major orogenic gold deposits. The gold endowment of these deposits exceeds 6,200 t (~200 Moz), making the Abitibi greenstone belt one of the economically most important metamorphic terranes in the world.
Volcanogenic Massive Sulfide Deposits of the Noranda Camp
Authors: Monecke Thomas , Gibson Harold L. , Goutier Jean 
Published: July 2019

Abstract
The Noranda camp in the southern Abitibi greenstone belt comprises over 20 volcanogenic massive sulfide deposits hosted by volcanic rocks of the 2704–2695 Ma Blake River Group. Decades of research and exploration have provided a firm understanding of the characteristics of these deposits as well as the geological controls on deposit location. Observations made on the deposits of the Noranda camp significantly contributed to the syngenetic model of massive sulfide formation and shaped the current understanding of ancient and modern sea-floor hydrothermal systems.
The Horne and Quemont deposits, which are the largest deposits in the Noranda camp, are hosted by 2702 Ma felsic volcanic successions dominated by volcaniclastic rocks. The massive sulfide ores of these deposits largely formed through processes of subseafloor infiltration and replacement of the highly permeable wall rocks. Laterally extensive hydrothermal alteration halos dominated by chlorite and sericite surround the replacement ores. The Horne deposit formed in an extensional setting in a graben bounded by synvolcanic faults. Rapid extension accompanying deposit formation resulted in the upwelling of mantle-derived mafic melts and the emplacement of a thick package of mafic rocks in the stratigraphic hanging wall of the deposit.
Most of the massive sulfide deposits in the Noranda camp are hosted by a 2700–2698 Ma bimodal volcanic succession that formed in a large volcanic subsidence structure to the north. The ~2,000-m-thick lava flow-dominated volcanic package is floored by the large, multiphase, synvolcanic Flavrian pluton. The deposits in this part of the Noranda camp are small (&lt;5 million tonnes) and primarily formed as sulfide mounds on the ancient sea floor. Synvolcanic structures provided cross-stratal permeability for the hydrothermal fluids and controlled the location of volcanic vents. Thin tuffaceous units mark the sea-floor positions hosting the massive sulfide mounds within the flow-dominated volcanic succession. The concordant massive sulfide lenses overlie discordant alteration pipes composed of chlorite- and sericite-altered rocks. Contact metamorphism associated with the emplacement of the ~2690 Ma Lac Dufault pluton converted the hydrothermal alteration pipes into cordierite-anthophyllite assemblages.
Recent brownfields exploration successes have demonstrated that massive sulfide discoveries are still possible in one of Canada’s most mature mining camp through three-dimensional geological modeling performed at the camp scale. Geologic target generation through computer modeling has reversed the general trend of progressively deeper exploration with time in the Noranda camp. Deep exploration currently focuses on the reevaluation of a previously uneconomic low-grade ore zone at the Horne deposit.

Medezeggenschap ten aanzien van benoeming, beloning en ontslag van bestuurders: veel bevoegdheden, weinig invloed
Vanwege maatschappelijke onrust is de positie van de OR ten aanzien van beloning, benoeming en ontslag van bestuurders sinds 2000 aanzienlijk uitgebreid. De OR heeft informatierechten, standpuntbepalingsrechten en een adviesrecht zonder beroep. Recent is daar een overlegrecht over de beloningsverhoudingen bij gekomen. In deze bijdrage bespreekt de auteur deze bevoegdheden en vergelijkt ze deze met elkaar. Leiden al die bevoegdheden daadwerkelijk tot meer invloed van de OR op de beloning, benoeming en het ontslag van bestuurders?

Fabulaciones. La astucia de los mitos
Authors: Campra Rosalba 
Published: July 2019

El texto es un testimonio del itinerario de la autora a partir de su descubrimiento en la infancia de los mitos clásicos, que coincide con el descubrimiento de los distintos niveles de la lengua, y prosigue con el acercamiento al mundo mítico prehispánico. La realidad de los mitos y su persistencia en busca de nuevas voces se vuelve la materia de la propia escritura ficcional y de exploraciones en el campo de la imagen, experiencia aquí ilustrada a través de sus microrrelatos (tomados por lo general de R. Campra, Mínima Mitológica) y poemas (R. Campra, Moradas de los Mayores).
Tiempo mexicano: Miguel Ángel Tenorio y la teatralización del imaginario mítico contemporáneo
Authors: Di Matteo Angela 
Published: July 2019

Incorporada a su gramática dramatúrgica la perspectiva nacionalista de Rodolfo Usigli, Miguel Ángel Tenorio ha ido cuestionando, a lo largo de toda su producción, las figuras clásicas del imaginario mexicano para investigar una distinta representación del perfil histórico nacional. Con Travesía guadalupana(1996), que coloca en la actualidad contemporánea a los más poderosos personajes del pasado mitológico (Tonantzin, Coatlicue, Huitzilopochtli, Coyolxauhqui, Tezcatlipoca y Tlazoltéotl), Tenorio dibuja un viaje en las imágenes del estatuto ontológico de la memoria mítica y lleva al espectador al espacio circular de una superficie cronológica abierta, donde los distintos niveles temporales coinciden en un único supertiempo.
La reescritura poética de la historia inca en El enemigo y la mañana de Jorge Enrique Adoum
Authors: Gómez Soriano Miguel Ángel 
Published: July 2019

Se plantea un acercamiento crítico a la reescritura poética de la historia llevada a cabo en El enemigo y la mañanade Jorge Enrique Adoum. Este poemario, el segundo de la serie agrupada bajo el título Los cuadernos de la Tierra, toma como materia poética la expansión del Imperio Incaico hasta los territorios del actual Ecuador. El autor plantea una recreación de los mitos, la religiosidad, las costumbres y la historia del Tahuantinsuyo, en una labor de recuperación histórica nacida de una necesidad identitaria. Claro ejemplo de la reflexión histórica llevada a cabo en los años 50 y 60 del siglo pasado, el poemario expresa la conexión del pasado con la actualidad, en una crítica contra todo imperialismo y abuso de poder, al tiempo que esboza un nuevo mito para ese tiempo nuevo: el del patriota que lucha por su territorio, un mito que tiene evidentes conexiones con la filosofía del hombre nuevo expresada por Ernesto Che Guevara.
