FIRST DETECTION OF CHROMOSPHERIC MAGNETIC FIELD CHANGES DURING AN X1-FLARE
Authors: Kleint Lucia 
Published: December 2016

ABSTRACT
Stepwise changes of the photospheric magnetic field, which often becomes more horizontal, have been observed during many flares. Previous interpretations include coronal loops that contract, and it has been speculated that such jerks could be responsible for sunquakes. Here we report the detection of stepwise chromospheric line-of-sight magnetic field (B

) changes obtained through spectropolarimetry of Ca ii 8542 Å with DST/IBIS during the X1-flare SOL20140329T17:48. These changes are stronger (<640 Mx cm−2) and appear in larger areas than their photospheric counterparts (<320 Mx cm−2). The absolute value of

more often decreases than increases. Photospheric changes are predominantly located near a polarity inversion line, and chromospheric changes near the footpoints of loops. The locations of changes are near, but not exactly co-spatial to hard X-ray emission and neither to enhanced continuum emission nor to a small sunquake. Enhanced chromospheric and coronal emission is observed in nearly all locations that exhibit changes of

, but the emission also occurs in many locations without any

changes. Photospheric and chromospheric changes of

show differences in timing, sign, and size and seem independent of each other. A simple model of contracting loops yields changes of the opposite sign to those observed. An explanation for this discrepancy could be increasing loop sizes or loops that untwist in a certain direction during the flare. It is yet unclear which processes are responsible for the observed changes and their timing, size, and location, especially considering the incoherence between the photosphere and the chromosphere.

ABSTRACT
Studying the Milky Way disk structure using stars in narrow bins of [Fe/H] and [α/Fe] has recently been proposed as a powerful method to understand the Galactic thick and thin disk formation. It has been assumed so far that these mono-abundance populations (MAPs) are also coeval, or mono-age, populations. Here we study this relationship for a Milky Way chemodynamical model and show that equivalence between MAPs and mono-age populations exists only for the high-[α/Fe] tail, where the chemical evolution curves of different Galactic radii are far apart. At lower [α/Fe]-values an MAP is composed of stars with a range in ages, even for small observational uncertainties and a small MAP bin size. Due to the disk inside-out formation, for these MAPs younger stars are typically located at larger radii, which results in negative radial age gradients that can be as large as 2 Gyr kpc−1. Positive radial age gradients can result for MAPs at the lowest [α/Fe] and highest [Fe/H] end. Such variations with age prevent the simple interpretation of observations for which accurate ages are not available. Studying the variation with radius of the stellar surface density and scale height in our model, we find good agreement to recent analyses of the APOGEE red-clump (RC) sample when 1–4 Gyr old stars dominate (as expected for the RC). Our results suggest that the APOGEE data are consistent with a Milky Way model for which mono-age populations flare for all ages. We propose observational tests for the validity of our predictions and argue that using accurate age measurements, such as from asteroseismology, is crucial for putting constraints on Galactic formation and evolution.
Baisse de la fécondité dans un contexte d’amélioration du statut des femmes ?
Authors: Lebugle Mojdehi Amandine 
Published: December 2016

La forte baisse de la fécondité observée en milieu rural iranien dans la seconde moitié du xx	e siècle interroge. Comment, dans un contexte d’isolement international, de prédominance de la religion, les populations rurales ont-elles réduit leur fécondité ? Pour y répondre, la question du statut des femmes est posée : a-t-on assisté à une meilleure égalité entre les sexes ? La baisse de la fécondité est-elle survenue alors que le déséquilibre des sexes prévaut toujours ? Trois dimensions du statut de la femme sont mobilisées ici : l’éducation, le travail et, au sein de la famille, l’entrée en vie maritale et la pratique contraceptive. S’appuyant sur des données de recensements, d’enquêtes socio-démographiques et d’une enquête de terrain, l’étude se focalise sur la société rurale, là où les transformations ont été les plus spectaculaires de par leur ampleur et leur rapidité.
Immigration et statistiques en Guyane
Authors: Cambrézy Luc 
Published: December 2016

Le département français de la Guyane se caractérise par une forte immigration dont le poids joue un rôle considérable dans l’évolution et la structure de la population. Mais les statistiques accessibles sur le sujet sont peu nombreuses, très formatées, et se révèlent à l’analyse difficiles à croiser et à interpréter. Plus grave, elles sont souvent peu fiables du fait de l’importance de la population « clandestine » mais aussi de la manière dont l’Institut national de la statistique et des études économiques (Insee) opère une distinction entre populations française et étrangère. Comme en écho à la perception floue sinon tronquée de la question migratoire, la population guyanaise est elle-même fortement segmentée par l’importante diversité ethnique et culturelle (Amérindiens, Noirs-marrons, Créoles, etc.). Ce « flou démographique » est au fond à l’image du caractère composite de la société guyanaise. Mais il en traduit aussi les ambiguïtés dans un contexte où l’immigration constitue la toile de fond des diverses revendications d’autochtonie qui s’expriment et qui interrogent sur l’identité guyanaise, ou ce que d’aucuns nomment encore la « guyanité ». Comprendre comment la mesure des phénomènes migratoires s’en trouve affectée permet de mieux appréhender cette réalité complexe.
South Africa in African agriculture : Investment models and their dynamics towards a structured conquest
Authors: Anseeuw Ward , Boche Mathieu 
Published: December 2016

Le capital agraire et entrepreneurial de l’Afrique du Sud investit aujourd’hui dans l’agriculture de 28 pays africains, à travers les exportations de ses agriculteurs, son agroindustrie en amont et en aval, et son expertise technique et de gestion. Ces investissements sont souvent soutenus par le gouvernement sud-africain, à travers des traités bilatéraux d’investissement et des accords commerciaux préférentiels. Cet article présente, sur la base d’un travail empirique approfondi, différents modèles selon lesquels l’Afrique du Sud est en train de conquérir le secteur agricole sur le continent, faisant valoir qu’il n’y a pas de « modèle sud-africain unique ». Il évalue également la dynamique et l’évolution de ces investissements, en précisant le nombre élevé des échecs, leur besoin de s’intégrer verticalement et la manière dont une dynamique plus organisée se structure actuellement. Bien qu’il semble que la présence sud-africaine sur le continent soit là pour durer, l’article remet en question ses implications réelles globales pour la transformation agraire de l’Afrique.
Bajaj en Égypte ou la diffusion discrète de l’ autorickshaw en Afrique
Authors: Tastevin Yann Philippe 
Published: December 2016

Moyen de transport populaire en Inde, le rickshaw à moteur part, au tournant du xxi	e siècle, à la conquête du monde. En Égypte, le succès commercial de la technologie indienne montre de manière exemplaire comment à l’axe nord-sud des importations s’ajoutent des flux d’investissement et de technologie entre l’Inde et le continent africain, à l’insu des constructeurs qui dominent la filière automobile. Partant de l’exemple de Bajaj, leader indien aujourd’hui de taille mondiale sur le marché des deux et trois roues, nous proposons d’explorer dans une perspective ethnographique une configuration qui, entre Inde et Égypte, inclut à la fois des individus et des dispositifs industriels. De l’importation à la distribution du véhicule, de l’échange rentable de pièces détachées à sa mécanique, de la filière égyptienne à son extension en Afrique, il s’agira d’analyser les pratiques et la stratégie d’une firme du Sud en voie de multinationalisation.
Des collaborations équivoques
Authors: Oberhauser Pierre-Nicolas 
Published: December 2016

Lorsqu’ils s’investissent dans des projets de recherche impliquant la mise en place d’une infrastructure numérique dédiée, les chercheurs en sciences humaines et sociales (SHS) sont amenés à collaborer avec des spécialistes des sciences et techniques informatiques (STI). Ces collaborations constituent un aspect important des transformations qu’impliquent les humanités numériques pour la recherche en SHS. Cet article en identifie certaines caractéristiques à partir d’un travail de terrain ethnographique auprès d’une équipe de recherche en psychologie du développement rattachée à un laboratoire d’humanités numériques. Nous décrivons dans un premier temps la vigilance qu’impliquent ces collaborations pour les chercheurs, qui sont régulièrement amenés à s’interroger sur la qualité des contributions des spécialistes en STI avec lesquels ils collaborent et sur leur adéquation aux objectifs poursuivis par le projet. Dans un second temps, nous revenons sur les efforts de planification déployés par les chercheurs pour assurer le bon déroulement du projet. Nous montrons comment ces efforts s’appuient de manière prépondérante sur les informations transmises par les spécialistes en STI et cherchons à éclairer les conséquences de cette dépendance épistémique. Le matériau analysé consiste en des entretiens semi-directifs avec les membres de l’équipe, des observations ethnographiques de situations de travail et des enregistrements vidéo de réunions rassemblant les différents participants au projet.
A Young Adult with Unintentional Acute Parenteral Iron intoxication Treated with Oral Chelation: The Use of Liver Ferriscan.
Authors: De Sanctis Vincenzo 
Published: December 2016

Acute iron poisoning in humans has not been adequately studied. Toxicity depends on the severity of iron overload. Manifestation of acute iron poisoning, defined as a serum iron concentration >300 µg/dL (55 µmol/L) within 12 hours of ingestion, by oral route include numerous symptoms which appear in progressive stages. Systemic toxicity is expected with an ingestion of 60 mg/kg. A 27 year old female nurse presented to hematology department with iron toxicity 1 week after self-injecting herself with 20 ampoules of IV iron (4000 mg elemental iron, 60 mg/kg). Her vital signs were stable but she had mild hepatic tenderness.
IS THERE A ROLE FOR MINIMAL RESIDUAL DISEASE MONITORING IN FOLLICULAR LYMPHOMA IN THE CHEMO-IMMUNOTHERAPY ERA?
Authors: Gritti Giuseppe , Pavoni Chiara , Rambaldi Alessandro 
Published: December 2016

After 25 years, evaluation of minimal residual disease (MRD) in follicular lymphoma (FL) has become a standardized technique frequently integrated in clinical trials for its consistent and independent prognostic significance. Achievement of a sustained MRD negativity is a marker of treatment sensibility that has been associated with excellent clinical outcome in terms of clinical response and progression-free survival, independently from the employed therapy. However, no survival advantages has been reported for MRD negative patients and despite the compelling results of clinical trials, MRD evaluation has currently no role in clinical practice. Ongoing clinical trials will help in clarifying the potential setting in which MRD monitoring may have a routine clinical application i.e. allowing de-escalation of standard maintenance therapy in very low risk patients. In this review the clinical implications of MRD monitoring in Rituximab-era are discussed in light of the current treatment paradigms most aimed at reducing toxicities, and the response definition that now routinely integrates PET scan.

Minimally Invasive Video-assisted Thyroidectomy vs Conventional Open Hemithyroidectomy in Asian Patients
Authors: Singaporewalla Reyaz M , Rao Anil D , Majumder Arunesh 
Published: December 2016

ABSTRACT

Introduction
Although the technique of minimally invasive video assisted thyroidectomy (MIVAT) is well established in continental Europe, data on it's role in Asian patients is limited. We compared the results of MIVAT with conventional open hemithyroidectomy in Asian patients.

Materials and methods
Over a 1-year period, patients undergoing hemithyroidectomy for benign symptomatic goiters were selected. Inclusion criteria for MIVAT were benign colloid goiters, recurrent cysts or follicular lesions and neoplasms with lobe volume of less than 40 cc or nodule diameter less than 35 mm. Larger goiters underwent conventional open surgery. Patients with previous neck surgery and proven malignancy were excluded. Operative time, complications, postoperative pain score, incision length and cosmetic satisfaction at 6 months were recorded.

Results
Thirty-six patients (MIVAT-21, Conventional-15) were included. Both groups were comparable in terms of demographic profile and co-morbidities. The mean operating time for both groups showed no significant difference (MIVAT = 111.67 ± 19.4 min, Conventional = 112.40 ± 25.06 min; p = 0.925). Minimally invasive video assisted thyroidectomy patients had significantly less pain in the immediate postoperative period (mean pain score 2.38 vs 4.8, p < 0.001). Mean incision length at end of surgery was significantly smaller in the MIVAT group (2.58 vs 6.3 cm; p < 0.001). Neck scar satisfaction at 6 months was excellent in 71.4% of MIVAT cases vs 26.6% of conventional hemithyroidectomy cases. There were no complications in any of the treatment groups.

Conclusion
In selected cases, MIVAT is as safe as conventional open surgery with distinct advantages of better postoperative pain control and cosmesis.

Ultrasound-guided Ethanol Ablation: Where does It fit in the Treatment of Recurrent Metastatic Papillary Thyroid Cancer?
Authors: Seiser Natalie , Pasternak Jesse D , Kluijfhout Wouter , Gosnell Jessica E , Shen Wen T 
Published: December 2016

ABSTRACT

Introduction
Ethanol (ETOH) ablation of metastatic neck nodes has been described as a potentially safe and effective alternative to surgical excision. We sought to describe a subset of these patients well suited for ETOH ablation.

Materials and methods
We report ultrasound-guided ETOH ablation of metastatic papillary thyroid cancer (PTC) at a Tertiary Care Endocrine Surgery Unit over 5 years. A retrospective review of all reoperative lymph node dissections was undertaken. Ethanol injection was used as second-line treatment to operative excision and was standardized with ultrasound guidance and the use of 1 cc/cm3 of 100% ETOH solution.

Results
Five treatments of ultrasound-guided ETOH ablation were studied. All patients had been previously treated with radioactive iodine (RAI) (mean: 1.25 treatments of 174mCi), however, in three cases with pretreatment I-131 scan, no uptake of radioiodine was seen in the treated disease. In four cases with pretreatment fludeoxyglucose-positron emission tomography (FDG-PET), treated lesions were avid. Median follow-up time for treatment was 28.5 months, with no disease progression in all ablated lesions. Serum thyroglobulin (Tg) values in patients without Tg-antibody were lower after treatment. There were no complications.

Conclusion
Surgeons seeking a less-invasive approach for nodal metastases in the neck can consider ETOH ablation. Small ultrasound detectable lesions in scarred necks (irradiated and/or reoperative) which are radioiodine non-avid and FDG-PET avid may be best suited for this treatment. As demonstrated by a small set of patients in a Tertiary Care Endocrine Surgery Unit, ETOH ablation is safe and effective at controlling progression of targeted local disease.

Large Substernal Thyroid Goiter Associated with Saddle Pulmonary Embolism
Authors: Nelson Daniel W , LoPinto Melissa , Sidani Charif , Lew John I 
Published: December 2016

ABSTRACT
A 75-year-old woman with a longstanding history of a substernal thyroid goiter presented with acute shortness of breath, and she was intubated due to respiratory distress. Computed tomography (CT) scan revealed a compressive substernal goiter with associated vascular compression, axillosubclavian thrombosis, and saddle pulmonary embolism. Weight-based heparin was immediately administered, and the patient subsequently underwent successful thyroidectomy via a cervical incision. This case report of a rare saddle pulmonary embolism associated with a substernal thyroid goiter underscores the importance of early elective thyroidectomy. Successful management of these potentially devastating pulmonary emboli (PE) associated with large substernal goiters is possible.

Surgical Techniques for operating on Large Adherent Cervical Nodal Metastases from Thyroid Cancer causing Severe Neck Pain and Compression Effects and encasing Major Vessels
Authors: Singh Kul R , Rana Chanchal 
Published: December 2016

ABSTRACT

Aim
We aim to refine and define surgical techniques for doing difficult adherent bulky cervical nodal metastases from thyroid cancer to help surgeons do dissections with better curability and lesser morbidity.

Background
Patients with thyroid cancer with large nodal metastases presenting with severe neck pain due to compression effects and encasing carotid artery and other major vessels pose a challenge to surgeons to do complete resections while preserving important structures in the neck.

Materials and methods
We define surgical planning and road map to dissect difficult bulky adherent cervical nodes encasing carotid artery and jugular vein by splaying the plane over carotid sheath by doing adventitial level dissection and dissecting medial and lateral to carotid sheath the large nodal mass adherent to adjacent structures preserving the major vessels and nerve plexus.

Conclusion
By appropriate surgical planning and meticulous dissection techniques, we can do major neck dissections with complete resections and same time preserving important structures in the neck minimizing morbidity.
Clinical significance: By doing neck dissections with complete oncological resections and saving vital structures in the neck, we aim to offer best possible chance of cure to the patient along with reduced morbidity at same time.

Influence of Age on Factors associated with Peri-implant Bone Loss after Prosthetic Rehabilitation over Osseointegrated Implants
Authors: Ramos Adilson Luiz , Pedro Rejane EL , De Carli João P , Linden Maria SS , Lima Igor FP , Costa Max D , Bós Ângelo JG 
Published: December 2016

ABSTRACT

Introduction
To verify the influence of age on factors associated with peri-implant bone loss after prosthetic rehabilitation over osseointegrated implants.

Materials and methods
This is an analytical, observational, and longitudinal study with initial 23 participants. Patients presenting with osseointegrated implants with their respective prostheses installed were included, and they could be carriers of chronic and degenerative diseases, such as diabetes, osteoporosis, hypothyroidism, cardiovascular disease (CVD), and systemic arterial hypertension. Thus, 18 participants with 57 implants were selected and followed up from 2009 to 2013. For statistical analysis, chi-square or Fisher's exact test was used for the association of systemic conditions and bone loss. Student's t-test was used for mean comparisons of age and number of total upper and lower implants.

Results
The average age of the sample studied was 71.05 years (65–80). The average implant per person was 3.2. Smoking had an influence on both mesial and distal bone loss, and the latter was significant (p = 0.0370). The association between bone loss and gender was also significant (p < 0.05). Moreover, male gender and upper implants were factors significantly associated with bone loss. The systemic conditions, when isolated, did not have significant influence on implant survival.

Conclusion
Age is not a factor that, alone, contraindicates implant-rehabilitating therapy. On the contrary, smoking has a significant influence on dental implant survival. Systemic diseases, such as osteoporosis, hypothyroidism, diabetes, hypertension, and heart diseases, when controlled, are not contraindication factors.

Clinical significance
This study is relevant for assessing peri-implant bone loss in elderly patients, right after implant installation and over time. Therefore, it was possible to verify that age is not a limiting factor for this procedure. Controlled systemic diseases do not contraindicate implant installation, but smoking is a factor that affects implant survival.

Prevalence, Location, and Size of Maxillary Sinus Septa: Computed Tomography Scan Analysis
Authors: Taleghani Ferial , Tehranchi Maryam , Shahab Shahryar , Zohri Zahra 
Published: December 2016

ABSTRACT

Introduction
The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT).

Materials and methods
In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evaluated in relation to their prevalence, height, and position; t-test and Mann–Whitney tests were used for the analysis of data.

Results
Sinus septa were detected in 44% of the subjects, with equal frequencies in the anterior, middle, and posterior positions. The mean height of the septa was 3.6 ± 1.56 mm.

Conclusion
In a population of Iranian subjects, in half of the cases, the sinus septa might be present in the anterior, middle, and posterior positions.

Clinical significance
In order to avoid intraoperative problems during sinus lift procedures, it is necessary to accurately evaluate the sinus, preferably with the use of CBCT.
