Published: September 2017

<p class="keywords"><span lang="EN-IN">Schwannoma is a rare neoplasm of nose and PNS which develops from Schwann’s cells of neural sheath and most are benign and encapsulated and amenable to surgical excision. The aim of this write-up is to report a rare case of schwannoma of nose and PNS. We report a case of 40 year old female, a housewife, presented in ENT OPD with complaints of nasal obstruction on right side, post nasal drip and headache. On diagnostic nasal endoscopy, there was a polypoidal mass coming from the middle meatus which was pushing the medial turbinate medially. NCCT and MRI of nose and PNS showed soft tissue density mass involving right ethmoidal air cells, maxillary sinus and bilateral sphenoid sinuses and eroding the lateral wall of right maxillary sinus reaching upto infratemporal fossa, superiorly mass was seen eroding the inferior wall of right orbit. The tumour was removed endoscopically piecemeal and sent for histopathology which showed it to be a schwannoma. The conclusion of the finding was schwannoma involving nasal cavity, maxillary sinus and sphenoid sinus eroded the lateral wall of maxillary sinus going into infratemporal fossa and floor of the orbit. Schwannoma should also be kept as a possibility in the differential diagnosis of tumors of nose and PNS. </span></p>

The aim: demonstration of our experience of surgical treatment of patients with migrated intrauterine device (IUD) into the abdominal cavity.
The results of surgical treatment of migrated IUDs in the pelvic cavity are summarized in 17 women. The average age of the patients was 33,23,4 years. The timing of implantation of the IUDs varied from 10 days to 24 months. In all cases, the intra operational finding was T-shaped a copper device.
The reason behind the women's consultation was an increase in pain syndrome in the lesser pelvis (n=15), dysuric phenomenon (n=1) and the onset of pregnancy (n=1). Perforation of the uterus and migration of the spiral occurred from 10 days to 2 years after its implantation. All patients were operated laparoscopicaly.
The average duration of operations was 45,510,5 minutes. In the postoperative period there were no complications from the pelvic organs and postoperative wounds. The period of hospitalization of patients was 3,50,7 days. In all cases there was a regression of clinical signs and recovery. In one pregnant patient (gestation period 5-6 weeks) the pregnancy proceeded without particular pathological abnormalities and resulted in the birth of a full-term child.
Laparoscopic removal of the IUD migrating from the uterine cavity to the abdominal cavity is the method of choice in the treatment of this group of patients, avoiding development of intra- and postoperative complications and a shorter length of stay in the hospital. The effectiveness of the procedure reaches 100%. The most common cause of complication of the IUD is the perforation of the uterus during its implantation.

Abstract
OBJECTIVE To assess pulmonary hemodynamics and alveolar oxygenation in dogs anesthetized with propofol or isoflurane during one-lung ventilation (OLV) in a closed-thoracic experimental model.
ANIMALS 6 healthy Beagles.
PROCEDURES Dogs were anesthetized with each of 3 protocols (constant rate IV infusion of propofol [0.4 to 1.0 mg/kg/min], isoflurane at the minimum alveolar concentration [MAC], and isoflurane 1.5 MAC), with a 7-day washout period between anesthetic sessions. During each session, dogs were intubated with a double-lumen endotracheal tube, positioned in right lateral recumbency, and administered atracurium (0.1 to 0.2 mg/kg, IV, q 30 min) to allow mechanical ventilation throughout a 2-hour observation period. Dogs underwent two-lung ventilation for 30 minutes, OLV of the right lung for 1 hour, and two-lung ventilation for another 30 minutes. Pulmonary hemodynamic and blood gas variables were evaluated at predetermined times and compared among protocols and over time within each protocol.
RESULTS Alveolar oxygenation was not impaired, and mean heart rate and pulmonary artery pressure and occlusion pressure were similar among the 3 protocols. One-lung ventilation caused a significant increase in the arteriovenous shunt fraction only when dogs were anesthetized with isoflurane at 1.5 MAC. Dogs developed respiratory acidosis, which was exacerbated by OLV, during all anesthetic sessions.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated pulmonary hemodynamics and alveolar oxygenation during OLV in a closed-thoracic model were similar regardless of whether dogs were anesthetized with propofol or isoflurane. One-lung ventilation can be successfully performed in dogs by use of a double-lumen endotracheal tube and either propofol or isoflurane.
Desain Konseptual Speech Recognition di Komunikasi Pesawat untuk Mengurangi Kesalahan Komunikasi Penerbangan
Authors: Widiastuti Nur Oktaviani 
Published: September 2017

Penyebab utama kecelakaan penerbangan adalah human error (55%) dengan salah satu penyebab adalah miskomunikasi. Miskomunikasi menjadi penyebab kasus kecelakaan terbesar di dunia seperti kecelakaan antara Pan Am dan KLM, Garuda dengan nomor penerbangan 152, dan kecelakaan yang baru-baru ini terjadi antara Batik Air dan Transnusa. Selain itu, KNKT pernah mengalami kebingungan saat menginvestigasi cockpit recorder Air Asia QZ8501. Saat miskomunikasi terjadi, instruksi sering kali sulit dipahami dan diperlukan pengulangan komunikasi, yang mempersempit waktu pengambilan tindakan. Penelitian ini ingin mengembangkan konsep speech recognition dengan sistem voice sign and text untuk prosedur pengecekan komunikasi kru penerbangan. Metode dalam penelitian ini adalah kajian pustaka dan perancangan sistem. Hasil dari penelitian ini adalah penambahan prosedur komunikasi dengan sign dan teks yang diperoleh dengan bantuan speech recognition. Pesan teks berasal dari ucapan yang diterjemahkan oleh speech recognition menjadi teks, kemudian teks akan diubah menjadi sign. Lalu sign dan teks akan ditampilkan dan dilihat langsung oleh pilot. Dengan penambahan sistem sign dan teks disamping komunikasi melalui suara diharapkan kesalahan dapat diminimalisir, pengambilan keputusan dapat dilakukan dengan cepat, dan kecelakaan dapat dihindari.
[Speech Recognition Conceptual Design in Aircraft Communications to Reduce Flight Communication Mistake] The main cause of aviation accidents is the human error (55%) in which one of its factor is the miscommunication. Miscommunication involved in the most accidents in the world including Pan Am and KLM accident, Garuda flight 152 (the biggest accident in Indonesia), and that was recently occurred between Batik Air and Transnusa Airline. Moreover, NTSC was confused when investigating the Air Asia QZ8501 cockpit recorder. When miscommunication occurs, the repetition of communication is prominently required due to the difficulty in understanding the instruction, which later narrowed the time to take any action. This study is intended to develop the concept of speech recognition with voice sign and text system for flight crew communication checking procedure. The methodology that is used in this research is the combining of literature review and system design. The results of this study is the addition of communication procedure by means of sign and text that obtained from speech recognition process. The text is produced from the translation of voice by speech recognition and converted into sign afterwards. Both of sign and text will be displayed, thus can be seen by the pilot. In addition to communication by voice, the implementation of sign and text is expected in minimalizing the error, supporting faster decision making, and avoiding the accident.
Analisis Flutter Pada Uji Model Separuh Sayap Pesawat N219 di Terowongan Angin Kecepatan Rendah

Published: September 2017

Fenomena flutter akan terjadi apabila ada gaya dan momen aerodinamika yang berinteraksi berlebihan di permukaan sayap di dalam terowongan angin atau pesawat sesungguhnya. Sayap akan bergetar dan berosilasi bertambah besar menuju ke keadaan tidak stabil. Osilasi osilasi membuat osilasi yang lebih besar terjadi sehingga frekuensi dan damping pada daerah kecepatan tertentu dengan mudah terlihat apabila terjadi flutter pada model separuh sayap. Penelitian ini, digunakan model separuh sayap dari pesawat N219 yang di uji pada terowongan angin kecepatan rendah BBTA3, kawasan Puspiptek, Serpong. Kecepatan flutter terjadi pada 40,5 m/s pada hasil analisis komputasional dan hasil pengujian di terowongan angin sebesar 40,83 m/s.

[The Analysis of Half Wing Flutter Test N219 Aircraft Model in The Low Speed Wind Tunnel] The flutter phenomenon will occur when the aerodynamic force and moment excessively interacted on the wing surface, whether it takes place in the wind tunnel or on the real aircraft. The wing will vibrate and oscillate towards an unstable condition. Each oscillation will subsequently build a greater one until the damping and frequency on a certain speed range can be seen easily when flutter occur on the half wing model. On this research, the half wing model of N219 aircraft was tested in the low speed wind tunnel of BBTA3, Puspitek Serpong. The flutter speed occurred at 40,5 m/s based on computational analysis while the wind tunnel result is at the speed of 40,83 m/s.
Ice Stream C, Antarctica, sticky spots detected by microearthquake monitoring
Authors: Anandakrishnan S. , Alley R. B. 
Published: September 2017

Microearthquakes at the base of slow-moving Ice Stream C occur many times more frequently than at the base of fast-moving Ice Stream B. We suggest that the microearthquake source sites are so-called “sticky spots”, defined as limited zones of stronger Subglacial material interspersed within a weaker matrix. The fault-plane area of the microearthquakes (O (102m2)) is therefore a measure of the size of the sticky spots. The spatial density of the microearthquakes (O (10 km-2)) is a measure of the distribution of sticky spots.The average stress drop associated with these microearthquakes is consistent with an ice-stream bed model of weak subglacial till interspersed with stronger zones that support much or all of the basal shear stress. We infer a weak inter-sticky-spot material by the large distances (O (103 m)), relative to fault radius, to which the microearthquake stress change is transmitted.
Seasonal variations of major ionic concentration levels in drifting-snow samples obtained from east Dronning Maud Land, East Antarctica
Authors: Osada Kazuo 
Published: September 2017

Drifting-snow samples were collected at Mizuho Station (74°42' S, 44°20' E, 2230 m a.s.1.) from February to October 1986 and along traverse routes in east Dronning Maud Land (1800-3000 m a.s.1.), East Antarctica, from October 1986 to January 1987. The typical sampling interval was about once a week but two sets of intensive sampling were made at the end of February and November at between 2 h and 1 d intervalsMeasurements for CI-, NO3,SO42and Na+ were made on the drifting-snow samples by ion chromatography. Oxygen-isotope ratios were .also measured .on the samples. Concentrations levels ofNO3-and SO4-show distinctive seasonal variations: high in summer (4.6 neq g-1 for NO3 and 3.3 neq g1 for SO42) and low in winter during mid-March to mid-November(1.0 neq g1 for NO3 and 0.5 neq g1 for SO42). Results obtained at Mizuho Station show that the transition from the summer high values to winter low values takes about 20 d for NO3 and SO42-.The variations in Cl and Na+ concentration levels are small in both autumn and spring (averages are about 1 neq g-l) with greater variability throughout the rest of the year. The intensive sampling data set shows that there is considerable variability within a day with NO3 and SO42- concentration levels up to about a factor of 4 associated with a 10%0 change in 3180 ratios.
The oceanic environment beneath the northwest Ronne Ice Shelf, Antarctica
Authors: Robinson Allan , Makinson Keith , Nicholls Keith 
Published: September 2017

Oceanographic data have been obtained from beneath the Ronne Ice Shelf at a site on the southeastern side of a sea-floor trough, the Ronne Depression. The data consist of 5 d of conductivity temperature depth (CTD) profiling and a long-term temperature record from a thermistor cable. The water column was found to be composed of two layers: a cold buoyant layer of lce Shelf Water (ISW) overlying a layer of unmodified Western Shelf Water (WSW).A change in the water column was observed on the last day of profiling, the WSW layer thinning, a cold intrusion appearing directly above the WSW and the ISW becoming colder. In addition, on three profiles the ISW cooled further and increased in salinity, becoming apparently statically unstable. The temperature record from the thermistor cable confirms that the ISW layer occasionally becomes colder. with greater variation in temperature than seen on the CTD profiles. These low temperatures and high salinities arc interpreted as indicating that water containing ice crystals in suspension has been advected beneath the site.
Melting and freezing beneath ice shelves: implications from a three-dimensional ocean-circulation model
Authors: Determann J. , Gerdes R. 
Published: September 2017

The thermohaline circulation below a regularly shaped ice shelf comparable in dimensions to the Ronne Ice Shelf, Antarctica, is investigated by means of a three-dimensional primitive-equation model. To handle the strongly inclined ocean surface as well as the bottom topography, we use scaled coordinates in the vertical direction. Preliminary results of two model versions containing open and closed open-ocean boundaries, respectively, prove the internal circulation is almost independent of the hydrography outside the ice shelf.Merely driven by the pressure-dependence of the sea-water freezing point (-0.000753 K dbar-1), a stationary circulation pattern evolves, forced by the buoyancy flux due to melting and freezing. The redistribution of ice from deep to shallow ice-shelf drafts resembles the ice-pump mechanism. Its strength depends on the ice-thickness gradients, namely, the differences of the freezing point at the ice-shelf base. As simulated melting and accumulation rates convincingly reproduce the interactions observed at the base of the Ronne Ice Shelf, the present model can act as a tool coupling ice-ocean dynamics.
A digital elevation model of the Antarctic ice sheet derived from ERS-1 altimeter data and comparison with terrestrial measurements
Authors: Bamber Jonathan L. 
Published: September 2017

The launch of ERS-1 provides coverage, by satellite altimetry, of 80% of the Antarctic ice sheet, allowing topographic mapping of areas which previously had a dearth of accurate elevation data. Four 35 d repeat cycles of fastdelivery altimeter data were used in this study, comprising a total of approximately 1000000 height estimates. About 40% of these were rejected during a careful filtering procedure designed to remove erroneous values caused by poor tracking or complete loss of the returned echo. The OSU-91A geopotential model was used to convert ellipsoidal elevations to geoidal values. Corrections for surface slope were applied and a Digital Elevation Model (DEM) was produced with a grid spacing of 20km.The precision of the data was assessed from an analysis of crossing points of ascending and descending tracks. For 43864 cross-overs, the standard deviation was 6.8m. Regional biases associated with geoid, orbit and topography-induced errors reduce the accuracy of the height measurements. This was assessed by a comparison with ground-survey data. The DEM was compared with a 700km levelling survey, with an accuracy ranging from 1 to 5m, from the Lambert Glacier basin region (≈73° S, 55° E). The mean difference was found to be-1.6m with a standard deviation of 14m. A similar result was obtained for a 600km traverse line in Wilkes Land (75° S,≈1l0° E).The DEM was then compared with a digitized version of the Scott Polar Research Institute (SPRI) Antarctic folio map. This map was derived from orthometric measurements of surface elevation, primarily from pressure altimetry. Differences in excess of 300 m were observed between the two data sets. Only 37% of the region covered showed agreement to better than 50m, and a significant proportion ofthis was composed of the Ross and Filchner-Ronne Ice Shelves. The largest discrepancies occurred in marginal areas where there is poor coverage by both satellite altimetry and terrestrial data. Inland, significant differences were also found.
Pour en finir avec la pensée psychanaloïde réactionnaire
Authors: Vidaillet Bénédicte 
Published: September 2017

La pensée réactionnaire et sa réussite au plan politique comme médiatique ont prospéré à partir de représentations totalement erronées de la société. Que dire quand ces représentations sont alimentées par une certaine psychanalyse qui s’autorise à intervenir de manière extrêmement normative sur de nombreux sujets de société, participant ainsi de manière décisive à discréditer l’ensemble de la psychanalyse, embrigadée pour soutenir les postures les plus réactionnaires. Ce texte propose d’identifier ce qui fait le noyau de cette pensée psychanaloïde à prétention sociologique et de retracer de quelle manière elle se constitue progressivement comme soubassement d’une « expertise » erronée sur la société. En contre-point, il donne aussi l’occasion de réfléchir aux conditions auxquelles la psychanalyse pourrait s’articuler à la fois aux travaux et recherches en sciences humaines et sociales pour faire signifier et y articuler la clinique, et s’inscrire plus franchement dans les pensées critiques contemporaines.
Les signifiants de Marine Le Pen
Authors: Wahnich Stéphane 
Published: September 2017

Le discours est l’essence même du politique. Tout commence par la parole qui permet avant toute action d’exprimer son idéologie, sa vision de la société et des individus. C’est par le discours que l’on peut conquérir le pouvoir. Historiquement, le Front national le sait bien. Pour Jean-Marie Le Pen, les mots constituent une « arme en politique » et Marine Le Pen l’a bien appris. C’est la raison pour laquelle, à l’instar de son père, les discours de Marine Le Pen sont travaillés, les mots sont ciselés afin que les signes émis par le discours soient les bons. Incapable électoralement de pouvoir gouverner ne serait-ce qu’une petite partie du territoire de France, Marine Le Pen sait que seul le discours lui permet d’exister politiquement. En politique, les mots précèdent les actes, Marine Le Pen va faire de l’usage discursif un enjeu existentiel. Cet article se propose de mettre en lumière les ressorts des mots de Marine Le Pen : la catholicité, les peurs, le complot, les signifiants…
La présentation clinique dans la pratique et la transmission de la psychanalyse : un acte analytique
Authors: Vidaillet Bénédicte 
Published: September 2017

La présentation clinique constituait pour Jacques Lacan un élément essentiel de la transmission de la psychanalyse au même titre que les textes, la cure et les études de cas cliniques, alors que cette pratique est initialement associée à la grande tradition de la formation en psychiatrie. La question traitée dans ce texte est alors la suivante : en quoi – et à quelles conditions – la présentation clinique, pratiquée sous la forme d’un entretien unique entre une personne hospitalisée dans un service psychiatrique, qui a accepté cet entretien proposé par l’équipe soignante, et un psychanalyste, devant un public de personnes concernées par la psychanalyse, est-elle bien le lieu d’un acte analytique ?
IL-22 Increases Permeability of Intestinal Epithelial Tight Junctions by Enhancing Claudin-2 Expression

Published: September 2017

Abstract
Dysfunction of the epithelial barrier is a hallmark of inflammatory intestinal diseases. The intestinal epithelial barrier is maintained by expression of tight junctions that connect adjacent epithelial cells and seal the paracellular space. IL-22 is critical for the maintenance of intestinal barrier function through promoting antipathogen responses and regeneration of epithelial tissues in the gut. However, little is known about the effects of IL-22 on the regulation of tight junctions in the intestinal epithelium. In this study we report that IL-22 signals exclusively through the basolateral side of polarized Caco-2 cell monolayers. IL-22 treatment does not affect the flux of uncharged macromolecules across cell monolayers but significantly reduces transepithelial electrical resistance (TEER), indicating an increase of paracellular permeability for ions. IL-22 treatment on Caco-2 monolayers and on primary human intestinal epithelium markedly induces the expression of Claudin-2, a cation–channel-forming tight junction protein. Furthermore, treatment of IL-22 in mice upregulates Claudin-2 protein in colonic epithelial cells. Knocking down Claudin-2 expression with small interfering RNA reverses the reduction of TEER in IL-22–treated cells. Moreover, IL-22–mediated upregulation of Claudin-2 and loss of TEER can be suppressed with the treatment of JAK inhibitors. In summary, our results reveal that IL-22 increases intestinal epithelial permeability by upregulating Claudin-2 expression through the JAK/STAT pathway. These results provide novel mechanistic insights into the role of IL-22 in the regulation and maintenance of the intestinal epithelial barrier.

Published: September 2017

AbstractPost-traumatic portal venous thrombosis is a rare event, and is usually seen in association with penetrating injuries. Portal venous thrombosis following blunt abdominal trauma is extremely rare with only few reports in the literature, some associated with underlying coagulation disorders. We report multidetector computed tomography findings in a case of blunt abdominal trauma with otherwise normal coagulation profile, which showed shattered spleen and MDCT evidence of acute thrombosis in the right branch of the portal vein. To the best of our knowledge, this is the first documented report of acute portal venous thrombosis in association with shattered spleen.
Horizontal gaze palsy with progressive scoliosis – A case report
Authors: Shalini P , Shah Virna M 
Published: September 2017

AbstractHorizontal gaze palsy with progressive scoliosis (HGPPS) is a rare congenital disorder characterized by absence of conjugate horizontal eye movements and accompanied by progressive scoliosis developing in childhood and adolescence. It occurs due to mutation in ROBO 3 gene/chromosome 11q23-q25. We report a case of a 60-year-old lady who presented with complaints of defective vision in both eyes. On examination, she had scoliosis with restricted abduction and adduction in both eyes with intact elevation and depression. Magnetic resonance imaging of the brain and orbit showed brainstem hypoplasia with absence of facial colliculi, presence of a deep midline pontine cleft (split pons sign), and a butterfly configuration of the medulla, which are the radiological findings seen in this disorder.
