Authors: Hafez Ahmed , Yousef Ali
Published: March 2020

This article analyzes thoroughly the performance of the Multi-Pulse Diode Rectifiers (MPDRs) regarding the quality of input/output voltage and currents. Two possible arrangements of MPDRs are investigated: series and parallel. The impact of the DC side connection on the performance of the MPDRs regarding the operation parameters and rectifier indices are comprehensively examined. Detailed analytical formulas are advised to identify clearly the key variables that control the operation of MPDRs. Moreover, comprehensive simulation results are presented to quantify the performance and validate the analytical analysis. Test-rig is set up to recognize the promising arrangement of MPDRs. Significant correlation is there between simulation and practical results. The analytical results are presented for aircraft systems (400Hz), and power grid systems (60Hz). This is to study the impact of voltage and frequency levels on the topology type of MPDRs. In general, each topology shows merits and have limitations.

Authors: V. Sudhakar , Chandram Karri , A. Jaya
Published: March 2020

This paper presents a novel approach, Equal Incremental fuel cost (λ-Concept) approach, for solving Multi Area Economic Dispatch (MAED) problem. It is a simple approach and developed from the basic observation of incremental fuel cost of an area. The proposed approach has been tested on 4-area system with four generators in each area and a large 2-area system consists of 120 generators. The suggested algorithm has been tested extensively by considering the different tie line power transfer limits and useful recommendations are provided. Further, the impact of tie line power transfer limits on total fuel cost is also discussed. It is found from the test cases that the proposed method is shown to be robust, very fast and extensible to include a large class of problems. The simulation results of the proposed method have been compared with the existing methods.

Published: March 2020

The residential electrical load in the city of Mosul as well as in most of cities in Iraq, is the major problem for the administration of electricity distribution. Since this kind of load is increasing drastically compared with other loads such as industrial, agricultural tourism and others which are declining for the last two decades due to unstable condition of the county.
The residential electrical load components must be determined to solve the problems resulting from the significant increase in this load. This research aims to conduct a field survey to find out and identify the components of the residential electrical load ratios and qualitative change in the months of the year. The survey was conducted in the city of Mosul in northern Iraq. The results were analyzed, and a number of recommendations were given to rationalize consumption.

Authors: Rashid Abdulmuttalib , Zayer Wael , Rashid Mofeed
Published: March 2020

A new algorithm for multi-object recognition and localization is introduced in this paper. This algorithm deals with objects which have different reflectivity factors and distinguish color with respect to the other objects. Two beacons scan multi-color objects using long distance IR sensors to estimate their absolute locations. These two beacon nodes are placed at two corners of the environment. The recognition of these objects is estimated by matching the locations of each object with respect to the two beacons. A look-up table contains the distances information about different color objects is used to convert the reading of the long distance IR sensor from voltage to distance units. The locations of invisible objects are computed by using absolute locations of invisible objects method. The performance of introduced algorithm is tested with several experimental scenarios that implemented on color objects.
Saturation Throughput and Delay Performance Evaluation of the IEEE 802.11g/n for a Wireless Lossy Channel
Authors: Alabady Salah
Published: March 2020

Non-ideal channel conditions degrade the performance of wireless networks due to the occurrence of frame errors. Most of the well-known works compute the saturation throughput and packet delay for the IEEE 802.11 Distributed Coordination Function (DCF) protocol with the assumption that transmission is carried out via an ideal channel (i.e., no channel bit errors or hidden stations), and/or the errors exist only in data packets. Besides, there are no considerations for transmission errors in the control frames (i.e., Request to Send (RTS), Clear to Send (CTS), and Acknowledgement (ACK)). Considering the transmission errors in the control frames adds complexity to the existing analysis for the wireless networks. In this paper, an analytical model to evaluate the Medium Access Control (MAC) layer saturation throughput and packet delay of the IEEE 802.11g and IEEE 802.11n protocols in the presence of both collisions and transmission errors in a non-ideal wireless channel is provided. The derived analytical expressions reveal that the saturation throughput and packet delay are affected by the network size (n), packet size, minimum backoff window size (Wmin), maximum backoff stage (m), and bit error rate (BER). These results are important for protocol optimization and network planning in wireless networks.
Short Circuit Faults Identification and Localization in IEEE 34 Nodes Distribution Feeder Based on the Theory of Wavelets
Authors: Authafa Sara
Published: March 2020

In this paper a radial distribution feeder protection scheme against short circuit faults is introduced. It is based on utilizing the substation measured current signals in detecting faults and obtaining useful information about their types and locations. In order to facilitate important measurement signals features extraction such that better diagnosis of faults can be achieved, the discrete wavelet transform is exploited. The captured features are then utilized in detecting, identifying the faulted phases (fault type), and fault location. In case of a fault occurrence, the detection scheme will make a decision to trip out a circuit breaker residing at the feeder mains. This decision is made based on a criteria that is set to distinguish between the various system states in a reliable and accurate manner. After that, the fault type and location are predicted making use of the cascade forward neural networks learning and generalization capabilities. Useful information about the fault location can be obtained provided that the fault distance from source, as well as whether it resides on the main feeder or on one of the laterals can be predicted. By testing the functionality of the proposed scheme, it is found that the detection of faults is done fastly and reliably from the view point of power system protection relaying requirements. It also proves to overcome the complexities provided by the feeder structure to the accuracy of the identification process of fault types and locations. All the simulations and analysis are performed utilizing MATLAB R2016b version software package.

Authors: Chudhary Shafiq Ahmad , Imtiaz Shahid , Iqbal Nedal
Published: March 2020

Since mid-December 2019, several cases of a pneumonia like disease (with symptoms including fever, difficulty in breathing, cough and invasive lesions on both lungs) of unknown cause have emerged in the central Chinese city of Wuhan. Chinese authorities made a preliminary determination that the causative agent is a novel coronavirus(2019-nCoV). Coronaviruses are enveloped RNA viruses belonging to Coronaviridae family and the order Nidovirales. This subfamily consists of four genera alphacoronavirus, betacoronavirus, gammacoronavirus and deltacoronavirus on the basis of their phylogenetic relationships and genomic structures. These subfamilies are broadly distributed for causing infections in humans and other mammals. The alphacoronaviruses and betacoronaviruses infect only mammals. The gammacoronaviruses and deltacoronaviruses infect birds, but some of them can also infect mammals. The source of betacoronavirus 2019-nCoV is still unknown, although initial cases have been linked with south Huanan seafood market. Viral infections already known to produce similar symptoms are influenza, parainfluenza, Middle East respiratory syndrome (MERS-CoV) and severe acute respiratory syndrome (SARS-CoV). Laboratory investigations reported raised plasma levels of L2, IL7, IL10, GSCF, IP10, MCP1, MIP1A, and TNF? in patients.
The Important In Terms of Health of Flax (Linum usitatissimum L.)
Authors: ARSLANOĞLU Funda , AYTAÇ Selim
Published: March 2020

The flax is one of the oldest known cultivated plants of the World that benefited from seeds and fibers. It is an important nutrient because of the rich α-linolenic acid (ALA, omega-3 fatty acid), lignans, short chain polyunsaturated fatty acids, soluble and insoluble fibers, phytoestrogenic lignans (secoisolariciresinol diglycoside-SDG), waxy and mucilage compounds, protein and antioxidant compounds. In addition, the seed contains components effective in reducing cardiovascular disorders, diabetes, digestive system, urinary tract disorders, osteoporosis, cancer, arthritis, autoimmune and neurological diseases. Seed protein content varies between 20-30%, of which approximately 80% consists of globulins and 20% glutelines. The amino acid level is so rich and gluten-free. The unconscious consumption of seed may cause toxicity due to trypsin, myo-inositol phosphate inhibitors, cadmium and cyanogenic glycosides in the seed. The seed should be consumed as milled flour after absolute heat treatment. Side effects may be seen in pregnant and young men due to hormonal effects of lignan. It may be oxidized shortly after grinding due to the fatty acids present in the seed. Flax fibers (Linen) have been used in house and fabric textiles, sailing and tent making since 7040 BC. The fibers are gold-yellow in color, the qualitative and moisture absorption capacity is very low, easily creasing. For this reason, the linen keeps the skin cool and does not sweat. Fiber is also an important source for healthy insulation materials, biocomposites, structural application materials for automotive, contributing both to the environment and to human health. In this paper, the effects of flax on human health and methods of traditional uses in Turkey were discussed with references.

Authors: Alaood Omar , Alasqah Mohammed , Alhomodi Nawaf , Alqahtani Noorah , Gufran Khalid , Shafiq Sami
Published: March 2020

BACKGROUND: Gingival recession has been associated with dentinal hypersensitivity, root caries, and esthetic compromise. Root coverage procedures aim at providing both tangible and intangible benefits to the patients. Various procedures have been tried to obtain root coverage of single-rooted teeth. Miller Classes I and II gingival recessions hold out the best promise for root coverage as there is no interdental bone and soft-tissue loss associated with these recessions.
AIM: The objective of the study was to evaluate and compare the effectiveness of coronally advanced flap (CAF) with platelet-rich fibrin (PRF) membrane with CAF + connective tissue graft (CTG) on recession coverage.
MATERIALS AND METHODS: A total of 16 patients required recession coverage for a single tooth were divided into two groups. The test group received CAF + PRF while the control group got CAF + CTG. Different parameters were taken preoperatively (amount of recession, width, and thickness of attached gingiva) and repeated for the two groups 2 months after surgery.
RESULTS: Comparing the two groups after 2 months from surgery showed that the PRF not only has an effect in the management of recession but also has a greater effect on tissue thickness.
CONCLUSION: PRF is a minimum invasive approach and a promising material for root coverage and manipulating the gingival biotype.

Published: March 2020

BACKGROUND: Mood disorders such as generalized anxiety disorder (GAD), obsessive-compulsive disorders, and other mental disorders could be due to obesity which is a prevalent condition among majority of population nowadays, whereas changes in anxiety level of individuals are also thought to have an influence on body mass index (BMI).
AIM: The objective of the study was to investigate the relationship between BMI and anxiety status among Ahlia University students.
METHODS: A total of 80 male and female students from different colleges of Ahlia University were included in our study. Their ages ranged between 18 and 25 years old with different BMI. The students were asked to fill a (GAD 7 scale) questionnaire related to anxiety level; their BMI was calculated.
RESULTS: There was a significant relationship between BMI and anxiety status (negative correlation) (p < 0.019).
CONCLUSIONS: We concluded that BMI is inversely proportional to anxiety level, the reduction in BMI level is linked with elevated anxiety level and vice versa.

Authors: Hendriyani Heni , Sudargo Toto , Lusmilasari Lely , Helmyati Siti , Susetyowati Susetyowati , Nindrea Ricvan Dana
Published: March 2020

BACKGROUND: Complementary feeding is a crucial aspect of childrenâ€™s health and growth. Few children receive nutritionally adequate and safe complementary foods that meet the criteria of dietary diversity and appropriate feeding frequency. Applied to nutrition, self-efficacy may predict which dietary behavior people feel capable of changing, how much effort they will expend while trying to adopt the new behavior, and how long they will persist in the face of obstacles.
AIM: This paper aimed to recognize the attributes of the concept of complementary feeding self-efficacy.
METHODS: A search was conducted for articles in the scientific literature through PubMed and ProQuest using search terms: Feeding practices, self-efficacy, mother, confident, maternal, and infant. A manual search was also performed, which included textbooks. Concept analysis was done with the method developed by Walker and Avant. Inclusion criteria were defined and a database created with the articles included for the analysis.
RESULTS: The concept of complementary feeding self-efficacy is defined as motherâ€™s beliefs in her ability to give adequate complementary food in terms of time, portion, frequency, and variety as well as to give safe and hygiene foods. It also involves creating a comfortable and warm environment while children are eating and to give appropriate responses toward any childâ€™s cues while eating, including hunger and satiety. Education of mother, type of family, occupation of father, occupation of mother, infantâ€™s health, and family income status are antecedents for these attributes. The consequences are changes in behavior of mothers, childrenâ€™s food intake improvement, and physical growth.
CONCLUSION: The attributes identified contribute to the understanding of the complementary feeding self-efficacy concept. These results could be used to design behavioral intervention.
Behçet syndrome as a construct
Authors: YAZICI Hasan
Published: March 2020

We still do not know the cause(s) of Behçet syndrome. Most probably several, separate disease mechanisms are involved. I, like some others, propose we call it not a disease but a syndrome, a construct with a list of strong and weak elements. I like to think that this frank admission of our ignorance of its cause(s) will be an important semantic stimulus for more meaningful research.
La dynamique du modèle d’affaires des start-ups dans le secteur des TIC, le cas des entreprises sociales au Sénégal
Authors: Ndour Mamour , Alexandre Laurice
Published: March 2020

Cet article tente de répondre à la question suivante : « comment les différents éléments du modèle d’affaires des start-ups sociales évoluent dans le temps dans un pays en transition ? ». Grâce à l’étude approfondie de 10 start-ups sociales dans le secteur des TIC au Sénégal, il a été démontré que le modèle d’affaires évolue selon les phases de développement des entreprises, et la proposition de valeur peut évoluer de trois façons : (1) l’adaptation de l’offre par modification ou changement de l’offre ; (2) l’enrichissement de l’offre de départ par l’ajout de services annexes ; (3) la création d’une nouvelle offre liée ou non à l’offre de départ pour la cible actuelle ou pour une nouvelle cible. Il semblerait également que le modèle d’affaires social sénégalais n’a pas encore atteint la phase de maturité d’un modèle d’affaires social d’une entreprise française.

Authors: Cazabat Gérard , Grama-Vigouroux Simona , Saidi Sana , Sellami Mohamed
Published: March 2020

La présente étude examine les facteurs quantitatifs et qualitatifs qui influencent la solvabilité des bénéficiaires de microcrédit notamment chez les hommes et femmes en France. Nous nous intéressons à trois catégories de facteurs liés au bénéficiaire de microcrédit, à son projet et à l’institution de microfinance. Nous étudions l’impact de ces facteurs sur la solvabilité auprès de 222 femmes et 468 hommes bénéficiaires de microcrédit. Il en ressort que la situation familiale constitue un facteur de solvabilité distinctif chez les femmes bénéficiaires de microcrédit tandis que la motivation entrepreneuriale l’est davantage chez leurs homologues masculins. Nos résultats montrent que les projets lancés dans le domaine commercial influencent la solvabilité chez les femmes, alors que les projets initiés dans le secteur industriel impactent la solvabilité chez les hommes. En outre, les projets innovants constituent un critère déterminant de la solvabilité des femmes bénéficiaires de microcrédit.
Exploration du cheminement appropriatif des personnels onusiens suite au déploiement du système d’information intégré UMOJA au sein de l’ONU
Authors: Kengue Mayamou Pascal
Published: March 2020

Cet article a pour objet d’explorer le processus d’appropriation du nouveau système d’information de l’Organisation des Nations Unies (ONU) qui repose désormais sur un Système d’Information intégré nommé UMOJA – « unité » en Swahili – et qui est basé sur un progiciel de type ERP. Le système, ses processus et ses technologies supports seront ici abordés sous l’angle de leur contribution fonctionnelle à la fabrique de l’ information de gestion. Cet article se propose de présenter et décrypter les spécificités et limites – notamment en termes multiculturels – de l’appropriation de UMOJA au travers d’un corpus théorique centré sur les théories de l’appropriation des outils de gestion (Rivard et al ., 2008 ; de Vaujany, 2006, 2009) et sur les théories du bricolage et de l’improvisation organisationnelle (Ciborra, 1997). La démarche méthodologique retenue est qualitative de type étude de cas unique et longitudinale. Elle est basée sur des entretiens d’experts et d’agents de divers sites et agences onusiens. Les résultats insistent sur la diversité et l’originalité des modalités d’appropriation du système UMOJA et sur les rôles majeurs des langues anglaises et swahili.
La capacité dynamique de résilience : l’aptitude à faire face aux événements perturbateurs du macro-environnement
Authors: Altintas Gulsun
Published: March 2020

L’objectif de cet article est d’analyser la capacité dynamique de résilience afin de comprendre comment elle peut permettre de gérer des événements perturbateurs issus du macro-environnement. Notre analyse des deux littératures montre que la capacité dynamique de résilience peut permettre de faire face à des événements perturbateurs à travers l’évolution des routines favorable à la mise en œuvre de réponses opérationnelles pour gérer une situation inédite. La capacité dynamique de résilience peut également générer un apprentissage post-crise favorable à la mise en œuvre de changements pour pallier les défaillances organisationnelles. De cette façon, construire une capacité dynamique est favorable au développement d’une résilience passive. La capacité dynamique de résilience peut également générer la modification récurrente des ressources et compétences, même en périodes de turbulences permettant ainsi d’éviter la chute des activités. Dans cette optique, construire une capacité dynamique est favorable au développement d’une résilience active.
Propagande : entre l’intérêt de la pratique et les limites de la notion

Il n’est pas rare d’affirmer qu’un gouvernement, une armée ou un groupe hors-la-loi fait de la propagande, ceci afin de le discréditer. En effet, nul ne veut reconnaître ou vertement qu’il utilise un tel mode de communication. Pourquoi la propagande est-elle une pratique inavouable mais nécessaire ? En quoi se distingue-t-elle des autres techniques de persuasion ?

De la perception à la perceptude
Authors: Breton Stéphane
Published: March 2020

La souffrance psychique est souvent associée à une perception étroite, intense et répétée d’un événement traumatique. Le plus souvent, cette sensation entraîne chez le patient une incapacité à vivre pleinement sa vie. En hypnothérapie, François Roustang a développé ce qu’il a appelé la perceptude : une expérience perceptive globale, non segmentée et hiérarchisée, qui permet de replacer la personne au centre de son corps redevenu vivant.

Depuis l’époque de transition du jazz vers les formes électro-amplifiées des années 1940 et d’avènement financier du rock en 1950, on peut dire que le reste (ce qui suit et se poursuit depuis cette époque) est affaire de politique et de business, avec la cohorte des labellisations contre-culturelles, protestataires, sociétales, underground, rituellement érigées par opposition à un passé forcément décevant, « récupéré », « impur », « commercial », et considéré, dans un discours assez convenu, comme trop formaté par le marché des industries culturelles…
L’utilisation du concept « Système National d’Innovation » dans les P.E.D. : quelle pertinence conceptuelle pour quels indicateurs ?
Authors: Casadella Vanessa , Tahi Sofiane
Published: March 2020

À la fois approche conceptuelle et outil de formalisation des politiques scientifiques, le Système National d’Innovation existe aujourd’hui sous de multiples terminologies, à travers une variété de conceptualisations cherchant toutes à donner de réels moyens d’action aux décideurs publics sur la problématique de l’innovation et du développement. Tout comme sa conceptualisation, la mise en place d’indicateurs a suscité de nombreux débats. Néanmoins, la communauté scientifique s’accorde à penser qu’ils restent indispensables, malgré leur méthodologie largement débattue. Avant de proposer un certain nombre d’indicateurs pertinents dans les P.E.D., nous reviendrons sur les caractéristiques actuelles des S.N.I. en développement ainsi qu’à leur grande hétérogénéité. L’intérêt de cet article est de justifier à la fois la pertinence du concept S.N.I. dans les P.E.D. malgré l’existence de réseaux d’innovation multi-scalaires et d’appliquer une grille méthodologie appropriée à cet effet.Classification JEL : O55, O11, O33.
Genesis and Geography of University–Industry Partnerships in France: When Interpersonal Ties Matter
Authors: Ferru Marie , Bès Marie-Pierre , Grossetti Michel
Published: March 2020

Some case studies have recently advanced our understanding of university-industry partnerships, showing that the relationships used to form such collaboration are a key factor. However, the weight of interpersonal relationships in the formation of University-industry partnerships remains to be measured more precisely, along with their impact on the geography of partnerships. This paper compiles relational data collected through semi-structured interviews, to identify the interpersonal relationships that impacted the formation of 244 such partnerships. A quantitative treatment reveals that 43% of partnerships were made possible by interpersonal ties, but that only non-professional ties have a significant impact on the geography of partnerships.JEL classification: D71, D85, O31.

Objectives: The objective of this study is to describe the imaging features of medulloblastoma (MB) and correlate the MR characteristics with the different histological subtype of MB with 2-year survival. Materials and Methods: This is a retrospective descriptive study. A total of 29 patients diagnosed with MB from January 2005 to December 2015 were included in this study. The MRI brain and spine studies of these patients were retrieved and reviewed by a pediatric radiologist and a neuroradiologist independently, both blinded from the histological type of the MB. The HPE slides were also retrieved and reviewed by a pathologist. Results: 80% of desmoplastic MB showed the presence of intracranial leptomeningeal seeding and 57.1% of anaplastic MB showed the presence of necrosis. The presence of intracranial leptomeningeal seeding (P = 0.002) and necrosis (P = 0.019) was predictive of the histological subtypes. There is a significant correlation between the enhancement pattern and the 2-year outcome (P = 0.03) with 6 out of 8 patients whose tumors showed minimal enhancement having disease progression within 2 years. A significant correlation was also seen between the presence of necrosis with a poorer outcome (P = 0.03) and between the HPE subtype and 2-year outcome (P = 0.03) with anaplastic MB having the poorest prognosis. Conclusion: MR imaging features of intracranial leptomeningeal seeding and the presence of necrosis were correlated with a specific histologic subtype of MB. The enhancement pattern as well as necrosis correlated with 2-year poorer outcome of the disease.

Background and Aims: Besides providing a surgical roadmap, rectal MRI plays a major role in treatment planning. We recently started using a structured template for reporting rectal cancer via MRI. We study the impact of using this template at our hospital in terms of number of essential imaging parameters described in the reports as compared to the pre-template free-text reports. Methods: A structured rectal MRI reporting template was created in consensus with members of the colorectal tumour board and was introduced in the department, which included 14 essential parameters to be mentioned in the reports. We conducted a retrospective analysis of rectal MRI reports of 100 cases with histologically proven rectal cancer, comprising 50 consecutive free-text reports before the template was introduced and 50 consecutive structured reports after its introduction, checking for the presence or absence of inclusion of the 14 parameters. An anonymous online feedback survey was conducted as well after the introduction of the template for the members of the colorectal tumour board. Results: Overall, the total number of parameters reported increased from a median value of 10 (range 6-13) to 14 (range 12-14). The common unreported parameters prior to template introduction included T staging, presence or absence of restricted diffusion, anterior peritoneal reflection (APR) involvement, and presence or absence of extramural vascular invasion; these were reported in 16%, 22%, 30% and 50% respectively. These improved to 98-100% reporting after template introduction. Maximum improvement was in T staging (16% to 98%) (P < 0.0001), restricted diffusion on DWI (from 22% to 100%) (P < 0.0001) and APR involvement (from 30% to 100%) (P < 0.0001). The most common unreported parameter after template introduction was the “tumoral T2 signal intensity” (unreported in 4% cases). The results of the survey were as follows: 100% felt a decreased need to talk to the radiologist to clarify the report, 81.8% felt an improvement in the quality of reporting as compared to free style reports, and 91% felt that the new template is easier to interpret. Conclusion: The introduction of a structured template for rectal cancer significantly improved the quality of rectal MRI reports, along with the satisfaction of referring providers.

Intralenticular abscess is a very rare entity that occurs after trauma, cataract surgeries, or as metastatic infection. It is important to pinpoint this sequestrated infection and to evacuate the abscess surgically to prevent chronic endophthalmitis. In this report, we describe a case of posttraumatic lenticular abscess highlighting the characteristic clinical features and their management. Additionally, here we report the first time use of Anterior Segment Optical Coherence Tomography as a diagnostic tool in delineating lens abscess from traumatic cataract which further guide the management and prognosis of the case.

Published: March 2020

Infertility is a major social and clinical problem affecting 13–15% of couples worldwide. The pelvic causes of female infertility are categorized as ovarian disorders, tubal, peritubal disorders, and uterine disorders. Appropriate selection of an imaging modality is essential to accurately diagnose the aetiology of infertlity, since the imaging diagnosis directs the appropriate treatment to be instituted. Imaging evaluation begins with hystero- salpingography (HSG), to evaluate fallopian tube patency. Uterine filling defects and contour abnormalities may be discovered at HSG but usually require further characterization with pelvic ultrasound (US), sono-hysterography (syn: hystero-sonography/saline infusion sonography) or pelvic magnetic resonance imaging (MRI), when US remains inconclusive. The major limitation of hysterographic US, is its inability to visualize extraluminal pathologies, which are better evaluated by pelvic US and MRI. Although pelvic US is a valuable modality in diagnosing entities comprising the garden variety, however, extensive pelvic inflammatory disease, complex tubo-ovarian pathologies, deep-seated endometriosis deposits with its related complications, Mulllerian duct anomalies, uterine synechiae and adenomyosis, often remain unresolved by both transabdominal and transvaginal US. Thus, MRI comes to the rescue and has a niche role in resolving complex adnexal masses, endometriosis, and Mullerian duct anomalies with greater ease. This is a review, based on the authors’ experience at tertiary care teaching hospitals and aims to provide an imaging approach towards the abnormalities which are not definitively diagnosed by ultrasound alone.

Published: March 2020

Context: High perinatal mortality in India may be caused by inaccurate dating of pregnancy resulting from suboptimal uptake of antenatal care and ultrasound services during pregnancy. Aim: To determine the discrepancy in the last menstrual period (LMP) assigned expected date of delivery (EDD) and ultrasound assigned EDD in pregnant women in a rural district of central India. Methods: Data from an ongoing cross-sectional screening program providing fetal radiology imaging in Guna district of Madhya Pradesh from 2012–2019 was analyzed for recall of LMP and discordance between LMP and ultrasound assigned EDD. The discrepancy was present when EDD assigned by ultrasound differed by 3 or more days at gestational ages less than 8+6 weeks, 5–7 days at gestational ages 8+6 weeks till 14 weeks, and 7–10 days at gestational ages 14–20 weeks. Results: The program screened 14,701 pregnant women of which 4,683 (31.8+6%, 95% CI: 31.11, 32.61) could not recall LMP. EDD assigned by LMP and ultrasound matched in 7,035 (70.22%, 95% CI: 69.32, 71.12) of the remaining 10,018 pregnant women. EDD was overestimated by LMP for 26.06% (95% CI: 25.21, 26.93) women; these foetuses were at risk of being misclassified as a term fetus. In 2018, the project had no maternal deaths, infant mortality rate of 24.7, low birth weight rate of 9.69%, and 100% antenatal coverage. Conclusion: Accurate dating of pregnancy and systematic follow-up integrating radiology imaging and obstetrics care for appropriate risk-based management of pregnant women can significantly improve perinatal statistics of India.

Published: March 2020

Intussusception is commonly associated with celiac disease in adults. However, it is rarely reported in children in radiology journals. Here, we report a case of a 3-year-old girl with celiac disease presented with complaints of intermittent abdominal pain, distension, and vomiting for 6 months. The patient was underweight (8.6 kg). Her X-ray of the abdomen standing revealed abnormal air-fluid levels and ultrasound of the abdomen revealed single small bowel intussusception. Contrast-enhanced CT abdomen done before planning surgery and it revealed five small bowel intussusceptions with few dilated small bowel loops. Her IgA antibodies to tissue transglutaminase were done to look for the cause of failure to thrive and its titer raised significantly. Gluten-free diet was started for her and symptoms were resolved within 7 days without surgical management.
