Total Knee Arthroplasty in a Case of Tuberculosis Knee in Healing Stage: Is it Safe?
Authors: Yadav Sanjay , Yadav Chandra Shekhar , Kumar Nishikant , Kumar Ashok 
Published: September 2015

ABSTRACT

Background
Association of tuberculosis and total hip joint replacement (THR) is described with or without antitubercular treatment (ATT) cover but total knee arthroplasty (TKA) in early disease in single-stage is uncommonly reported. We wish to share our clinical experience in such a case.

Case description
A 22-year-old male presented with pain and swelling of left knee for 7 months. It was drained at local health facility with sinus development. Tuberculosis was diagnosed by clinic-radiological evaluation and ATT was started. Sinus healed but disabling pain and knee stiffness with flexion deformity persisted. Radiographs revealed destructive osteoarticular arthritis with periarticular osteopenia. Debridement followed by TKA in single-stage was done with posterior-stabilized implant. Postoperative period was uneventful. Histopathological analysis confirmed chronic granulomatous synovitis with caseation necrosis suggestive of mycobacterial infection. After 1-year, ATT was discontinued and patient was disease-free.

Clinical relevance
Single-stage prosthetic knee joint arthroplasty can be safely performed under adequate ATT coverage in early disease provided response to medical treatment is good. Patient counseling regarding compliance with ATT and postoperative protocol is important in ensuring success.

Published: September 2015

ABSTRACT
Cerebrovascular disease (CVD) is the second most common cause of death and contributes to a high morbidity worldwide. The major etiology is an atherosclerosis. Many well-known risk factors, such as hypertension, dyslipidemia and diabetes, are defined as traditional risk factors. Treatment and control of traditional risk factors also improve both cardiovascular and cerebrovascular outcomes. To date, many studies reported an association between stroke and nontraditional risk factors, such as infectious diseases or inflammatory process. Periodontal disease (PD) is an infection of the gum and other toothsupporting structures, with an on going inflammatory process and affects a large number of populations worldwide. Current evidence demonstrated the local and systemic inflammatory effects in periodontitis induced an atherosclerosis. This review aims to provide the current knowledge on the association between periodontal disease and cerebrovascular disease.

Third Molar Socket Grafting after Surgical Extraction to prevent Periodontal Pocket Formation
Authors: Aljuboori Mohammed Jasim , Yi Ng Ying 
Published: September 2015

ABSTRACT
There is an incidence of periodontal pocket formation and gingival recession on the distal of the lower second molar due to bone defect after third molar surgical removal. Patient referred suffering from recurrent pericoronities; after clinical and radiographic examination, the lower left 3rd molar is partially erupted and angulated in mesial direction. The radiograph shows there is bone deficiency on the distal of the adjacent 2nd molar. After 3rd molar surgical removal, cancellous bone graft placed on the socket with guided bone regeneration (GBR) procedure and complete primary closure with rotational flap. Patient follow-up after 3 and 6 months, bone formation observed on the distal of 2nd molar with the absence of periodontal pocket. Third molar socket bone grafting with cancellous allograft may be a predictable procedure to prevent periodontal pocket on the distal of the second molar.

Esthetic Rehabilitation of Mutilated Anterior Teeth with Custom Cast Post and Core Porcelain-Fused-to-Metal Crowns
Authors: Saini Dinesh Kumar , Legha Virender Singh 
Published: September 2015

ABSTRACT
An endodontically treated anterior tooth requires extracoronal restoration when the tooth structure is weakened or lost due to caries, endodontic treatment, placement of previous restorations and/or is discolored. The reduced tooth structure makes retention of extracoronal restoration difficult. The purpose of post is to provide retention for the core restoration, which replaces lost coronal structure. This article describes restoration of mutilated maxillary central incisors by using cast post and core, followed with porcelain fused to metal restorations.

Home dealers, fixers and users-for-free. Residents and visitors of urban crack houses
This article is based on ethnographical research in 24 crack houses in Amsterdam, Rotterdam and The Hague. Crack houses were defined as the homes of crack users where crack is being sold and smoked together with other users. All crack houses were located in disadvantaged, multi-ethnic neighbourhoods. Both residents and visitors were men and women, middle-aged, of various ethnic origin and with a long history of hard drug use. In addition to economic benefits for residents (crack sales, getting crack for free from visitors) and sometimes also for visitors, crack houses predominantly serve as a safe haven for drug use and as a social meeting place. Two types of crack houses were found: dealing houses (with ‘home sellers’) and home circuits (divided into ‘fixers’ who arrange or facilitate that crack is available, and ‘users-for-free’, who allow that crack is sold or delivered and used in their apartment, in exchange for a bit of crack). To reduce the risk of discovery and closure, residents take various measures, but less if they are not a legal resident of the apartment. In comparison with the Anglo-Saxon literature about crack houses, there is less ethnic segregation, a less aggressive atmosphere and less involvement with prostitution.

Abstract

Context: Peyronie disease (PD) is a connective tissue disorder involving the formation of fibrous plaques in the tunica albuginea. Abnormal plaques and scar tissue create a chronic state of inflammation, causing increased curvature of the penis as well as erectile dysfunction.

Objective: To determine the feasibility and effects of using placental matrix–derived mesenchymal stem cells (PM-MSCs) in the management of PD.

Methods: In a prospective study, patients with PD were injected with PM-MSCs, and followed up at 6-week, 3-month, and 6-month intervals to assess changes in plaque volume, penile curvature, and erectile function status (measured using peak systolic velocity, end-diastolic velocity, and the International Index of Erectile Function questionnaire).

Results: In the 5 patients enrolled in the study, statistically significant increases in peak systolic velocity occurred after PM-MSC injection (P<.01). Of a total of 10 plaques managed, 7 had disappeared completely at 3-month follow-up. Changes in end-diastolic velocity, stretched penile length, and penile girth were not statistically significant.

Conclusion: To our knowledge, this study is the first on the use of stem cells to manage PD in humans. The results suggest that PM-MSCs may be beneficial and effective as a nonsurgical treatment in patients with PD. Future studies with long-term follow-up in a larger sample of patients are warranted.

A new dynamic fluid‐kinetic model for plasma transport within the plasmasphere
Authors: Wang Yan , Tu Jiannan , Song Paul 
Published: September 2015

AbstractA new dynamic fluid‐kinetic model is developed for investigating the plasma transport along a closed magnetic flux tube in the plasmasphere by coupling the field line interhemispheric plasma (FLIP) model with a generalized semikinetic (GSK) model. The coupling is achieved via an overlapped transition region (800 km–1100 km altitude) in each of the hemispheres. The flux tube is allowed to move both radially away from, toward, and azimuthally around the Earth. In addition to H+, ion species O+ and He+ are for the first time treated as simulation particles in a numerical model of the plasmasphere. The simulation particles are subjected to the field‐aligned electric field, magnetic mirror force, gravity, centrifugal force, and interspecies and intraspecies Coulomb collisions. The plasmaspheric refilling processes as an application of the model are studied. The simulation results show that the behaviors of O+ ions are substantially different from those of H+ and He+ ions.
Nighttime atomic oxygen in the mesopause region retrieved from SCIAMACHY O(1S) green line measurements and its response to solar cycle variation
Authors: Zhu Yajun , Kaufmann Martin , Ern Manfred , Riese Martin 
Published: September 2015

AbstractThis paper presents new data sets relating to the abundance of atomic oxygen in the upper mesosphere and lower thermosphere, which were derived from the nighttime green line emission measurements of the SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric CHartographY) instrument on the European Environmental Satellite (Envisat). These are compared to recently published data sets from the same SCIAMACHY green line measurements through the application of a different photochemical model and to data collected by the Sounding of the Atmosphere using Broadband Emission Radiometry instrument. We find that the retrieved atomic oxygen concentration depends on the choice of the underlying photochemical model. These dependencies explain a large proportion of the differences between recently published data sets. The impact of the 11 year solar cycle on volume emission rates and atomic oxygen abundances was analyzed for various data sets, with the finding that the solar cycle effect varies with the atomic oxygen data set used. The solar cycle impact on the SCIAMACHY data increases with altitude. Above 96 km, it is significantly larger than predicted by Hamburg Model of the Neutral and Ionized Atmosphere. Investigations indicate that these variations are primarily driven by total density compression/expansion variations during the solar cycle, rather than different photolysis rates.
MeV proton flux predictions near Saturn's D ring

AbstractRadiation belts of MeV protons have been observed just outward of Saturn's main rings. During the final stages of the mission, the Cassini spacecraft will pass through the gap between the main rings and the planet. Based on how the known radiation belts of Saturn are formed, it is expected that MeV protons will be present in this gap and also bounce through the tenuous D ring right outside the gap. At least one model has suggested that the intensity of MeV protons near the planet could be much larger than in the known belts. We model this inner radiation belt using a technique developed earlier to understand Saturn's known radiation belts. We find that the inner belt is very different from the outer belts in the sense that its intensity is limited by the densities of the D ring and Saturn's upper atmosphere, not by radial diffusion and satellite absorption. The atmospheric density is relatively well constrained by EUV occultations. Based on that we predict an intensity in the gap region that is well below that of the known belts. It is more difficult to do the same for the region magnetically connected to the D ring since its density is poorly constrained. We find that the intensity in this region can be comparable to the known belts. Such intensities pose no hazard to the mission since Cassini would only experience these fluxes on timescales of minutes but might affect scientific measurements by decreasing the signal‐to‐contamination ratio of instruments.
Learning By Tracing Worked Examples
Authors: Ginns Paul , Hu Fang‐Tzu , Byrne Erin , Bobis Janette 
Published: September 2015

SummaryCognitive load theorists have only recently begun to test the role of the body in learning. Tracing the index finger over the surface of instructions while reading, an embodied pedagogy based on Montessori's sandpaper letters, may hold substantial promise for learning by reducing cognitive load. Two experiments tested whether students who traced their index fingers against paper‐based worked example instructions in triangle geometry (Experiment 1; N = 52) and order of operations (Experiment 2; N = 54) would perform better on a subsequent test than students who only studied the materials visually. Students in the tracing condition outperformed the non‐tracing condition on transfer problems in both Experiment 1 (d = .78) and Experiment 1 (d = .50), but hypotheses regarding self‐reports of cognitive load during testing were not supported. Implications for research and practice are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

Published: September 2015

SummaryThe Self‐Administered Interview© (SAI) serves to elicit eyewitness statements directly after the crime. Witnesses could still experience stress then. Because stress during retrieval produces memory‐impairing effects, this study sought to compare the SAI with free recall under stress. An interaction between stress and interview was expected such that the SAI would elicit more comprehensive accounts than free recall in the control, but not in the stress group. One hundred and twenty‐seven participants underwent a stress or control task. They witnessed a live staged crime and completed an SAI or a free recall. The SAI elicited a higher number of correct verifiable event details and a higher number of correct and incorrect perpetrator details than free recall. Accuracy rates were unaffected. Unexpectedly, despite causing moderate stress‐induced cortisol elevations, stress exposure did not influence memory performance and did not interact with interview type. Hence, the SAI can safely be used, when witnesses are moderately stressed.Copyright © 2015 John Wiley & Sons, Ltd.
Prednisone Use and Risk of Mortality in Patients With Rheumatoid Arthritis: Moderation by Use of Disease‐Modifying Antirheumatic Drugs

Published: September 2015

ObjectiveMedications for rheumatoid arthritis (RA) may affect survival. However, studies often include limited followup and do not account for selection bias in treatment allocation. Using a large longitudinal database, we examined the association between prednisone use and mortality in RA, and whether this risk was modified with concomitant disease‐modifying antirheumatic drug (DMARD) use, after controlling for propensity for treatment with prednisone and individual DMARDs.MethodsIn a prospective study of 5,626 patients with RA followed for up to 25 years, we determined the risk of death associated with prednisone use alone and combined treatment of prednisone with methotrexate (MTX) or sulfasalazine. We used the random forests method to generate propensity scores for prednisone use and each DMARD at study entry and during followup. Mortality risks were estimated using multivariate Cox models that included propensity scores.ResultsDuring followup (median 4.97 years), 666 patients (11.8%) died. In a multivariate, propensity‐adjusted model, prednisone use was associated with an increased risk of death (hazard ratio [HR] 2.83 [95% confidence interval (95% CI) 1.03–7.76]). However, there was a significant interaction between prednisone use and MTX use (P = 0.03), so that risk was attenuated when patients were treated with both medications (HR 0.99 [95% CI 0.18–5.36]). However, combination treatment also weakened the protective association of MTX with mortality. Results were similar for sulfasalazine.ConclusionPrednisone use was associated with a significantly increased risk of mortality in patients with RA. This association was mitigated by concomitant DMARD use, but combined treatment also negated the previously reported beneficial association of MTX with survival in RA.

Published: September 2015

ObjectiveThe small size of many pediatric rheumatology programs translates into limited mentoring options for early career physicians. To address this problem, the American College of Rheumatology (ACR) and the Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed a subspecialty‐wide interinstitutional mentoring program, the ACR/CARRA Mentoring Interest Group (AMIGO). We sought to assess the impact of this program on mentoring within pediatric rheumatology.MethodsIn a longitudinal 3‐year study, participant ratings from the AMIGO pilot program were compared with those after the program was opened to general enrollment. Access to mentoring as a function of career stage was assessed by surveys of the US and Canadian pediatric rheumatologists in 2011 and 2014, before and after implementation of AMIGO.ResultsParticipants in the pilot phase (19 dyads) and the general implementation phase (112 dyads) reported comparable success in establishing mentor contact, suitability of mentor‐mentee pairing, and benefit with respect to career development, scholarship, and work‐life balance. Community surveys showed that AMIGO participation as mentee was high among fellows (86%) and modest among junior faculty (31%). Implementation correlated with significant gains in breadth of mentorship and in overall satisfaction with mentoring for fellows but not junior faculty.ConclusionAMIGO is a career mentoring program that serves most fellows and many junior faculty in pediatric rheumatology across the US and Canada. Program evaluation data confirm that a subspecialty‐wide interinstitutional mentoring program is feasible and can translate into concrete improvement in mentoring, measurable at the level of the whole professional community.

Published: September 2015

ObjectiveTo compare traditional cardiovascular (CV) risk factor management among patients with rheumatoid arthritis (RA) to that of matched non‐RA controls within a large US managed care setting.MethodsAdult patients with RA and age‐ and sex‐matched general population (general controls) or osteoarthritis (OA) controls were identified between January 1, 2007 and December 31, 2011. We compared health care utilization, measurement, treatment, and treatment target achievement of traditional CV risk factors among subgroups of CV comorbidity during 1 year of followup between RA and controls.ResultsA total of 9,440 RA patients, 31,009 general controls, and 10,352 OA controls were included. The proportions with measurements (blood pressure [BP], low‐density lipoprotein [LDL] cholesterol, or hemoglobin A1c), treatment (antihypertensive, statin, or anti–diabetes mellitus medications), and treatment target achievement were slightly higher in patients with RA compared with general controls. Controlling for other factors, RA patients were more likely to have a measurement of BP (odds ratio [OR] 16.77 [95% confidence interval (95% CI) 10.01–28.08]) or LDL cholesterol (OR 1.25 [95% CI 1.13–1.39]), and to receive antihypertensive (OR 1.84 [95% CI 1.47–2.30]) or anti–diabetic medications (OR 1.26 [95% CI 1.01–1.56]) compared to general controls. RA was not associated with receiving a statin (OR 1.01 [95% CI 0.92–1.12]); however, a target LDL level was more likely to be achieved in RA compared to general controls (OR 1.27 [95% CI 1.17–1.37]) as well as target levels of BP and hemoglobin A1c. These results were consistent with results for OA controls except for a lower probability of receiving a statin in RA compared to OA.ConclusionTraditional CV risk factors in patients with RA were not less aggressively managed compared to non‐RA controls.
