Abstract
We observed the nearly edge-on debris disk system HD 111520 at the HJ and K1 near-infrared (NIR) bands using both the spectral and polarization modes of the Gemini Planet Imager. With these new observations, we have performed an empirical analysis in order to better understand the disk morphology and its highly asymmetrical nature. We find that the disk features a large brightness and radial asymmetry, most prominent at shorter wavelengths. We also find that the radial location of the peak polarized intensity differs on either side of the star by 11 au, suggesting that the disk may be eccentric, although, such an eccentricity does not fully explain the large brightness and radial asymmetry observed. Observations of the disk halo with the Hubble Space Telescope also show the disk to be warped at larger separations, with a bifurcation feature in the northwest, further suggesting that there may be a planet in this system creating an asymmetrical disk structure. Measuring the disk color shows that the brighter extension is bluer compared to the dimmer extension, suggesting that the two sides have different dust grain properties. This finding, along with the large brightness asymmetry, are consistent with the hypothesis that a giant impact occurred between two large bodies in the northern extension of the disk, although confirming this based on NIR observations alone is not feasible. Follow-up imaging with the Atacama Large Millimeter/submillimeter Array to resolve the asymmetry in the dust mass distribution is essential in order to confirm this scenario.

Cette contribution traite des articles de géographie dans deux œuvres majeures de diffusion des savoirs au xviii e siècle : le Dictionnaire Universel de Trévoux et l’ Encyclopédie de Diderot et d’Alembert. L’étude est conduite sur un corpus échantillonné de cent huit articles présents dans les deux nomenclatures et traitant de la France. Les caractéristiques discursives les plus saillantes de ce corpus sont d’abord isolées pour chaque œuvre, puis comparées entre elles et avec celles observables dans plusieurs dictionnaires plus anciens qui furent souvent utilisés comme sources par les auteurs.
Le regard encyclopédique de l’ Académie française
Authors: Pruvost Jean 
Published: June 2022

Depuis 1694, l’ Académie française offre dans chacune de ses éditions, et jusqu’à la dernière en date (la neuvième), des articles conçus à partir des mêmes principes – à la logique de présentation des mots près, regroupés en familles dans la première édition. Un corpus d’une telle homogénéité offre un point de vue privilégié pour mesurer la marche de l’esprit encyclopédique à travers le parcours accompli par le mot encyclopédie depuis son traitement dans le Dictionnaire françois de Richelet (1680) jusqu’à celui qu’il reçoit dans la septième édition (1878) du Dictionnaire de l’Académie française , contemporaine du presque achèvement de l’œuvre de Larousse (1866-1890).
Penser l’à-venir grâce aux principes polanyiens d’intégration économique

Published: June 2022

Si le succès de Karl Polanyi peut paraître paradoxal du fait d’un retour des logiques du marché concurrentiel, de la propriété privée et de l’individualisme qu’il a critiquées, ses concepts ont la capacité d’éclairer certaines caractéristiques majeures des évolutions/involutions/révolutions en cours ; telles que la financiarisation généralisée, les nouvelles formes de marchandisation de l’humain, les limites écologiques de la production et la reconnaissance des biens communs. Est ici principalement argumenté le concept polanyien de principe d’intégration économique.
Local Vibration Therapy, Oxygen Resaturation Rate, and Muscle Strength After Exercise-Induced Muscle Damage
Authors: Percival Stuart , Sims Dave T. , Stebbings Georgina K. 
Published: June 2022

Context
Exercise-induced muscle damage (EIMD) is associated with transient reductions in strength and athletic performance. Muscle microvascular damage and disruption of blood flow are believed to be among the causes. Previous researchers reported modulations in muscle blood flow, oxygenation, and strength with vibration therapy (VT).

Objective
To observe whether local VT alleviated the impairments and hemodynamic changes associated with EIMD.

Design
Controlled laboratory study.

Setting
Laboratory and public gymnasium.

Patients or Other Participants
A total of 10 healthy participants (6 men and 4 women; age = 38 ± 15 years; height = 1.72 ± 0.48 m; mass = 72.0 ± 10.4 kg) were randomized into experimental (VT) and control groups.

Interventions
Both groups performed 10 sets of 10 eccentric wrist flexions at 70% of their 1-repetition maximum to induce muscle damage. Subsequent assessment of flexor carpus ulnaris muscle oxygen saturation and wrist-flexor strength occurred at 1, 24, and 48 hours postexercise. The experimental group underwent 10 minutes of local VT (45 Hz) starting 1 hour postexercise and applied twice daily (separated by 8 hours) for 48 hours during habitual waking hours. The control group received no local VT.

Main Outcome Measure(s)
Resting muscle oxygen saturation (SmO2), grip strength, and muscle oxygen desaturation and resaturation rates.

Results
No difference in SmO2 resaturation was evident over time (P &gt; .05), but the VT group had a greater resaturation rate than the control group at 1 hour (P = .007, d = 2.6), 24 hours (P = .001, d = 3.1), and 48 hours (P = .035, d = 1.7) post-EIMD. No difference in grip strength was observed pre-EIMD, but the VT group demonstrated greater strength at 1 hour (P = .004), 24 hours (P = .031), and 48 hours (P = .021) post-EIMD than did the control group.

Conclusions
Local VT successfully attenuated the effects of EIMD and increased SmO2 resaturation in flexor carpus ulnaris muscles. Including local VT as part of a recovery protocol post-EIMD could be beneficial for rehabilitation and strength training purposes.

Authors: Shah Rutvij Asitkumar , Bedi Varinder S , Yadav Ajay R , Agarwal Sandeep , Satwik Ambarish , Srivastava Apurva , Chaudhari Nikhil Vilas 
Published: June 2022

Background:
Varicose veins is a common disease in nearly 37.25% of the Indian population significantly affecting the quality of life. Endovenous thermal ablation has been the first-line treatment for superficial venous reflux. A new technique, available now, is nonthermal nontumescent vein sealing system (VenaSeal™), which comprises endovenous delivery of cyanoacrylate tissue adhesive into the vein causing obliteration of lumen and has shown better results in terms of safety and efficacy. Being a new modality, only handful of institutes across India perform this procedure and there is a scarcity of Indian data on its outcomes.

Aims and Objectives:
To evaluate the outcomes of VenaSeal™ glue ablation in terms of vein occlusion rates and improvement in Venous Clinical Severity Score (VCSS). Materials and Methods: Single-centre prospective study of fifty patients over 1 year and 4 months with 3- and 6-month follow-up.

Results:
The study showed the mean age of the study group to be 43.8 years and the majority (90%) had an early varicose vein (C2/C3) disease. The average length of vein treated per limb was 89.1 cm, and the average glue used per limb was 2.95 ml. All patients showed improvement in VCSS score from preoperative average of 2.6 ± 1.4 to 0.32 ± 0.19 (P < 0.0001, n = 89) with target vein occlusion rate of 100% at 3 months and 97.75% at 6 months.

Conclusion:
Thus, VenaSeal™ glue ablation procedure is a promising and effective modality for the treatment of varicose veins with excellent treatment success rates, minimal complications, and maximum patient acceptability. It is a feasible Out patient department (OPD) based procedure.

Published: June 2022

Background:
There is globally increase incidence in vascular trauma as a result of increase rate of civilian violence and increase rate of road traffic accident. Vascular injury affects young males and associated with high mortality and long-term morbidity. Here, we present our experience as tertiary health centers in the management of this type of injury, also we present our result as regards to primary and secondary amputation rates. The most important factors affecting these rates were ischemia time and condition of surrounding soft tissue.

Aims and Objectives:
Detect rate of limb salvage after trauma injury in assuit university hospital, and risk factors for limb loss.

Materials and Methods:
Our study is prospective study of all patients who vascular lower extremity trauma from January 2014 to January 2015 during the period of the study(from January 2014 to January 2015), 135 cases of vascular injury presented to Assiut University Hospital, 87 of them had lower limb vascular injury representing 64.4%.

Results:
Surgical intervention was done in 82 patients representing 94.3%, endovascular intervention was done in 2 patients representing 2.3, 1 patient had endovascular balloon control then surgical intervention representing 1.15%, and two patients had conservative management representing 2.3%.

Conclusion:
vascular trauma is prevalent health problem in our locality, which have huge socioeconomic impact in our community as it affects mainly young men. The main controlling factor in secondary amputation rate is ischemia time, infection which accompanies severe soft tissue damage. At the end trauma with vascular injury is considered, a complex process needs urgent intervention with multidisciplinary team in well-equipped facility.

Authors: Onkar Prashant Madhukarrao , Dhok Avinash Parshuram , Nimje Varun Vasant , Mane Priyanka Jayant 
Published: June 2022

Background:
Vertebral artery pathologies are not as common on ultrasound examination. Careful ultrasound examination of the vertebral artery can provide useful information about the proximal brachiocephalic vessels as well as the intracranial portion of the vertebral artery.

Objectives:
To illustrate a variety of vertebral artery pathologies on ultrasound and their abnormal color Doppler findings with confirmation of some cases on magnetic resonance imaging.

Materials and Methods:
A 3-12 MHz linear ultrasound probe was used to examine the vertebral artery segments. The examination began with a B-mode examination of the first and second portions of the vertebral arteries, followed by color Doppler examination to determine the direction of blood flow. Spectral Doppler is used to identify flow anomalies.

Conclusion:
Evaluation of proximal great vessels by ultrasound can sometimes be difficult, so careful examination of vertebral artery by ultrasound can be an important tool to detect occlusions or stenosis of proximal great vessels. In addition, vertebral artery waveforms in the cervical segment provide useful information regarding the intracranial portion of the vertebral artery.
Role of Ankle Brachial Pressure Index (ABI) in Screening Patients with Risk Factors For Developing Peripheral Vascular Disease
Authors: Yadav Mithilesh , Haseen Mohd Azam , Rizvi Syed Amzad Ali , Yadav Mayank 
Published: June 2022

Background:
Peripheral vascular diseases (PVDs) are trigged by various risk factors. The presence of PVD is associated with higher cardiovascular morbidity and mortality. Ankle brachial index (ABI) is the sensitive and also cost-effective diagnosing tool for peripheral artery disease. ABI is important for screening of peripheral arterial disease in patients at risk and for diagnosing the disease in patients having lower-extremity symptoms.

Materials and Methods:
This prospective observational study was performed at J. N. Medical College, A. M. U., Aligarh, UP on 135 adult patients who are asymptomatic for PVD but have one or more risk factors. Demographic and clinical data were recorded. Systolic Blood pressure of both arms and lower limb were measured using sphygmomanometer and hand held Doppler. Ankle brachial pressure index (ABPI) is detected by dividing higher of the two ankle pressures by the higher of the two brachial artery pressure.

Results:
Majority of the patients were aged between 46 and 65 years, males more than females. It was observed that diabetes, hypertension, smoking, and dyslipidemia patients have significantly lower ABPI score (<0.9) compared to other patients. USG Doppler has showed 10.4% were having abnormal findings and the ABI (0.68 ± 0.17) was significantly lower than the normal ones (0.89 ± 0.09). Receiver operating curve shows that ABPI below 0.77 can be used as cut-off to predict the occurrence and risk of developing PVD for screening asymptomatic with sensitivity 88.4 and specificity 85.7 and accuracy 90.1%.

Conclusion:
Comorbid conditions such as smoking, diabetes, hypertension, and dyslipidemia increase the risk of PVD. ABPI is a valid method to screen PVD with high levels of sensitivity and specificity.

Authors: Rastogi Devarshi , Singh Shailendra , Ozair Ahmad , Waliullah Shah , Singh Shitanshu Kumar , Srivastava Rajeshwar Nath 
Published: June 2022

Introduction
Total hip arthroplasty (THA) has a demonstrated utility in the surgical management of patients with proximal femoral fractures that fail internal fixation, with good outcomes reported from high-income countries. Given the lack of data from resource-limited settings, this work sought to report the clinical outcomes of THA for failed proximal femoral osteosynthesis from a low- and middle-income country (LMIC).

Methods
The work was conducted and reported in accordance with Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. A retrospective cohort study was carried out on all patients who underwent rescue THA for failed osteosynthesis of proximal femoral fractures, from January 2016 to June 2020, at a tertiary care center in Northern India. Primary study outcomes were functional outcomes as assessed by Harris Hip Score (HHS) at 1-year postoperatively and the frequency of perioperative complication as assessed by Clavien-Dindo-Sink Grading System.

Results
Twenty-eight patients with mean age of 43.25 ± 10.5 years were included, with 18 males and 10 females. For their femur fracture stabilization, the most common method used had been dynamic hip screw (n = 16, 57.1%), followed by cannulated cancellous screw (n = 6, 21.5%), proximal femoral nail (n = 3, 10.7%), dynamic condylar screw (n = 2, 7.1%), and Schanz Screw (n = 1, 3.6%). Causes of failure had included cut-out of screw (n = 14, 50.0%), avascular necrosis (n = 8, 28.6%), back-out of screw (n = 3, 10.7%), non-union (n = 2, 7.1%), and secondary osteoarthritis (n = 1, 3.6%). THA was carried out after mean 26.64 ± 9.01 months after index procedure. HHS improved significantly from 39.71 ± 10.89 preoperatively to 79.54 ± 4.22 at 1-year follow-up (mean difference 39.82, 95% confidence interval 43.66–35.98, P < 0.001). Perioperative complications occurred in two patients of Clavien-Dindo-Sink Grade III and another of Grade II, with no mortality occurring by 1 year.

Conclusions
In resource-limited settings like LMICs, THA may be a safe and efficacious surgical modality for failed osteosynthesis of proximal femoral fractures.

Authors: Jain Gunjar , Datt Rameshwar , Nag Hira Lal , Mahmood Asjad , Shekhar Shubhankar , Nag Tapas Chandra 
Published: June 2022

Background
In the present study, we have examined the ultrastructure of chronically failed reconstructed anterior cruciate ligament (ACL). We aimed to investigate a faulty ligamentization process of a failed reconstructed anterior cruciate ligament. In other words, we want to study ultrastructural alterations a failed ACL graft undergoes.

Methods
Two patients who underwent revision ACL reconstruction for nontraumatic failure without discontinuity of the graft were included in the study. The first patient was a 40-year-old male who had undergone ACL reconstruction of his right knee 21 years back using the bone-patellar tendon-bone autograft. The second patient was a 23-year-old male who had sustained an ACL tear with a medial collateral ligament injury treated by isolated ACL reconstruction 3 years back using hamstring tendon autograft. We collected punch biopsy specimens from the failed ligaments of both the patients during revision ACL reconstruction. These specimens were examined for the density of collagen fibrils within a fascicle (per 1.5 mm2), cellular metabolism, and fibril diameter (nm) by transmission electron microscopy.

Results
Fibroblasts of both the ligaments showed features of increased metabolism, more so in the first patient. Compared to the second patient, the fascicles of the first specimen were more loosely arranged. Both ligaments had a unimodal distribution of collagen fibrils. The first patient had a mean fibril diameter of 45.2 (+/−8.5) nm and an average fibril density of 376.8 fibrils per 1.5 mm2. The second patient had an average fibril diameter of 64.1 nm (+/−7) and a mean fibril density of 152.9 fibrils/1.5 mm2. The difference in these parameters of the two patients was statistically significant (P < 0.001).

Conclusion
Our study suggests that the absence of thicker collagen fibrils with unimodal distribution, the altered density of the collagen fibrils within a fascicle, and ovoid fibroblasts with increased metabolism may symbolize bad ligamentization changes.

Published: June 2022

Purpose
Glenohumeral joint (GHJ) osteoarthritis (OA) in younger patients represents a challenging problem. This study assessed the efficacy of intra-articular hyaluronate injection in patients below the age of 55 years.

Methods
We reviewed our patient database from August 2013 to December 2016 for patients who received a fluoroscopic-guided intra-articular injection of hyaluronate. Those who had received interventional procedures within the preceding 12 months were excluded. We evaluated the response to the injection using the Oxford Shoulder Score (OSS). These scores were recorded before injection and at 6 weeks, 12 weeks, and 26 weeks postinjection. Radiographs were reviewed independently by two evaluators, and the severity of GHJ OA was categorized (mild, moderate, or severe) using the Samilson–Prieto classification.

Results
Fifty-five patients were identified, with a mean age of 43 years (18.6–54.6 years). These cases were classified as being mild in 11 (20%), moderate in 21 (38%), and severe in 23 (42%) using Samilson-Prieto classification. In the severe group, there was a statistically significant improvement in the OSS at all time points. In the moderate group, there were statistically significant improvements at 6 weeks and 12 weeks but not at 6 months. In the mild group, there were no statistically significant changes.

Conclusion
In patients under the age of 55 years with moderate-to-severe GHJ OA, there is a significant improvement in the OSS up to 12 weeks after intra-articular injection of hyaluronate, with improvements lasting up to 26 weeks in more severe cases. Hyaluronate is, therefore, a useful treatment option in younger patients and may potentially delay the need for arthroplasty.

Published: June 2022

ABSTRACT
Spinal cervical extradural and intra-extradural hemangioblastomas are exceptional, with only nine reported cases. This study reviews the diagnostic and surgical problems of this rare entity. Two female patients, aged 80 years and 25 years, respectively, one with Von Hippel–Lindau disease (VHLD), experienced brachial pain and weakness. On magnetic resonance imaging, a dumbbell intra-extraspinal hemangioblastoma was evidenced. The surgical resection through posterior laminectomy resulted in clinical remission of brachial pain and weakness. The magnetic resonance aspect of a dumbbell lesion suggests a neurogenic tumor; the correct preoperative diagnosis is possible in individuals with VHLD. The surgical problems include high tumor vascularity, vertebral artery control, and nerve root preservation. However, the surgical excision results in clinical remission.

ABSTRACT
Treatment of atlantoaxial pathology is often associated with significant morbidity and mortality. While surgical techniques for fixation are well established, approaches that minimize blood loss and muscle dissection are advantageous for expediting recovering and minimizing surgical risk. We present a 34-year-old female who presented with a Type III odontoid fracture requiring surgical fixation. She underwent a C1-2 fusion employing a novel minimally invasive modification of the Goel-Harms atlantoaxial fusion using percutaneous screws and intra-articular cage.

ABSTRACT

Study Design:
This was retrospective cohort study.

Purpose:
The current investigation uses a large, multi-institutional dataset to compare short-term morbidity and mortality rates between current smokers and nonsmokers undergoing thoracolumbar fusion surgery.

Overview of Literature:
The few studies that have addressed perioperative complications following thoracolumbar fusion surgeries are each derived from small cohorts from single institutions.

Materials and Methods:
A retrospective study was conducted on thoracolumbar fusion patients in the American College of Surgeons National Surgical Quality Improvement Program database (2006–2016). The primary outcome compared the rates of overall morbidity, severe postoperative morbidity, infections, pneumonia, deep venous thrombosis (DVT), pulmonary embolism (PE), transfusions, and mortality in smokers and nonsmokers.

Results:
A total of 57,677 patients were identified. 45,952 (78.8%) were nonsmokers and 12,352 (21.2%) smoked within 1 year of surgery. Smokers had fewer severe complications (1.6% vs. 2.0%, P = 0.014) and decreased discharge to skilled nursing facilities (6.3% vs. 11.5%, P < 0.001) compared to nonsmokers. They had lower incidences of transfusions (odds ratio [OR] = 0.9, confidence interval [CI] = 0.8–1.0, P = 0.009) and DVT (OR = 0.7, CI = 0.5–0.9, P = 0.039) as well as shorter length of stay (LOS) (OR = 0.9, CI = 0.9–0.99, P < 0.001). They had a higher incidence of postoperative pneumonia (OR = 1.4, CI = 1.1–1.8, P = 0.002). There was no difference in the remaining primary outcomes between smoking and nonsmoking cohorts.

Conclusions:
There is a positive correlation between smoking and postoperative pneumonia after thoracolumbar fusion. The incidence of blood transfusions, DVT, and LOS was decreased in smokers. Early postoperative mortality, severe complications, discharge to subacute rehabilitation facilities, extubation failure, PE, SSI, and return to OR were not associated with smoking.
