DOUBLE-CELL-TYPE SOLAR MERIDIONAL CIRCULATION BASED ON A MEAN-FIELD HYDRODYNAMIC MODEL
Authors: Bekki Y. , Yokoyama T. 
Published: January 2017

ABSTRACT
The main object of the paper is to present the condition of the nondiffusive part of the Reynolds stress for driving the double-cell structure of the solar meridional circulation, which has been revealed by recent helioseismic observations. By conducting a set of mean-field hydrodynamic simulations, we confirm for the first time that double-cell meridional circulation can be achieved along with the solar-like differential rotation when the Reynolds stress transports the angular momentum upward in the lower part and downward in the upper part of the convection zone. It is concluded that in a stationary state, the accumulated angular momentum via the Reynolds stress in the middle layer is advected to both the upper and lower parts of the convection zone by each of the two meridional circulation cells, respectively.

Abstract
High-mass multiples might form via fragmentation of self-gravitational disks or alternative scenarios such as disk-assisted capture. However, only a few observational constraints exist on the architecture and disk structure of high-mass protobinaries and their accretion properties. Here, we report the discovery of a close (57.9 ± 0.2 mas = 170 au) high-mass protobinary, IRAS17216-3801, where our VLTI/GRAVITY+AMBER near-infrared interferometry allows us to image the circumstellar disks around the individual components with ∼3 mas resolution. We estimate the component masses to ∼20 and ∼18 M
⊙ and find that the radial intensity profiles can be reproduced with an irradiated disk model, where the inner regions are excavated of dust, likely tracing the dust sublimation region in these disks. The circumstellar disks are strongly misaligned with respect to the binary separation vector, which indicates that the tidal forces did not have time to realign the disks, pointing toward a young dynamical age of the system. We constrain the distribution of the Brγ and CO-emitting gas using VLTI/GRAVITY spectro-interferometry and VLT/CRIRES spectro-astrometry and find that the secondary is accreting at a higher rate than the primary. VLT/NACO imaging shows L′-band emission on (3–4)× larger scales than the binary separation, matching the expected dynamical truncation radius for the circumbinary disk. The IRAS17216-3801 system is ∼3× more massive and ∼5× more compact than other high-mass multiplies imaged at infrared wavelength and the first high-mass protobinary system where circumstellar and circumbinary dust disks could be spatially resolved. This opens exciting new opportunities for studying star–disk interactions and the role of multiplicity in high-mass star formation.

Objective.Several aspects of rituximab (RTX) retreatment in rheumatoid arthritis (RA) need to be further elucidated. The aim of this study was to describe the effect of repeated courses of RTX on disease activity and to compare 2 retreatment strategies, fixed-interval versus on-flare retreatment, in a large international, observational, collaborative study.Methods.In the first analysis, patients with RA who received at least 4 cycles with RTX were included. In the second analysis, patients who received at least 1 RTX retreatment and for whom information about the strategy for retreatment was available were identified. Two retreatment strategies (fixed-interval vs on-flare) were compared by fitting-adjusted, mixed-effects models of 28-joint Disease Activity Score (DAS28) over time for first and second retreatment.Results.A total of 1530 patients met the eligibility criteria for the first analysis. Significant reductions of mean DAS28 between the starts of subsequent treatment cycles were observed (at start of first treatment cycle: 5.5; second: 4.3; third: 3.8; and fourth: 3.5), suggesting improved response after each additional cycle (p < 0.0001 for all pairwise comparisons). A total of 800 patients qualified for the second analysis: 616 were retreated on flare and 184 at fixed interval. For the first retreatment, the fixed-interval retreatment group yielded significantly better results than the on-flare group (estimated marginal mean DAS28 = 3.8, 95% CI 3.6–4.1 vs 4.6, 95% CI 4.5–4.7, p < 0.0001). Similar results were found for the second retreatment.Conclusion.Repeated treatment with RTX leads to further clinical improvement after the first course of RTX. A fixed-interval retreatment strategy seems to be more effective than on-flare retreatment.

Published: January 2017

Objective.The Outcome Measures in Rheumatology (OMERACT) Shoulder Core Outcome Set Special Interest Group (SIG) was established to develop a core outcome set (COS) for clinical trials of shoulder disorders.Methods.In preparation for OMERACT 2016, we systematically examined all outcome domains and measurement instruments reported in 409 randomized trials of interventions for shoulder disorders published between 1954 and 2015. Informed by these data, we conducted an international Delphi consensus study including shoulder trial experts, clinicians, and patients to identify key domains that should be included in a shoulder disorder COS. Findings were discussed at a stakeholder premeeting of OMERACT. At OMERACT 2016, we sought consensus on a preliminary core domain set and input into next steps.Results.There were 13 and 15 participants at the premeeting and the OMERACT 2016 SIG meeting, respectively (9 attended both meetings). Consensus was reached on a preliminary core domain set consisting of an inner core of 4 domains: pain, physical function/activity, global perceived effect, and adverse events including death. A middle core consisted of 3 domains: emotional well-being, sleep, and participation (recreation and work). An outer core of research required to inform the final COS was also formulated.Conclusion.Our next steps are to (1) analyze whether participation (recreation and work) should be in the inner core, (2) conduct a third Delphi round to finalize definitions and wording of domains and reach final endorsement for the domains, and (3) determine which instruments fulfill the OMERACT criteria for measuring each domain.

Authors: Grace Sara F. , Cavuoto Kara M. , Shi Wei , Capo Hilda 
Published: January 2017

Purpose:
To describe the characteristics of the strabismus, surgical management, and outcomes of patients who underwent surgery for adult-onset esotropia.

Methods:
This was a retrospective case study of patients at an academic tertiary referral center who underwent surgical treatment of esotropia acquired at or after age 18 years. Primary outcome measures were resolution of diplopia in primary position and a deviation of 10 prism diopters or less in primary gaze. Additional clinical parameters were assessed.

Results:
Of 248 patients with adult-onset esotropia who underwent strabismus surgery, all experienced diplopia preoperatively except those with sensory esotropia. The four most common diagnoses were cranial nerve VI palsy in 36% (90 of 248), thyroid eye disease in 18% (45 of 248), age-related distance esotropia in 15% (38 of 248), and decompensated latent esodeviations in 13% (31 of 248) of patients. A variety of surgical procedures were employed, and adjustable sutures were used in 79% (196 of 248). Approximately 80% (158 of 197) of patients present at the 2-month postoperative follow-up visit were aligned within 10 prism diopters, and 72% (140 of 195) experienced resolution of diplopia. Success rates were significantly higher in patients with adjustable sutures. Reoperation rates were low overall at 15% (37 of 248) and were highest in cranial nerve VI palsies and lowest in age-related distance esotropia. Dose-response calculations showed a non-significantly smaller effect per millimeter of recession and resection in cranial nerve VI palsy and age-related distance esotropia.

Conclusions:
The causes of adult-onset esotropia are diverse. A variety of surgical approaches are employed and, in conjunction with adjustable sutures, provide a good rate of diplopia resolution and acceptable ocular alignment.

Morphological Evaluation of Meibomian Glands in Children and Adolescents Using Noncontact Infrared Meibography
Authors: Wu Yuan , Li Haili , Tang Yun , Yan Xiaoming 
Published: January 2017

Purpose:
To compare, in vivo, differences in meibomian gland morphology between children and adolescents.

Methods:

Sixty-nine patients were included in this study and divided into two groups: children (n = 31; age range: 3 to 11 years) and adolescents (n = 39; age range: 12 to 18 years). Images of meibomian glands were obtained by infrared meibography and analyzed using ImageJ software (developed by the National Institutes of Health; available at
http://rsb.info.nih.gov/ij/download.html
). Meibomian gland loss, the number of meibomian gland ducts, the relative width of the meibomian gland ducts, and the percent area of the meibomian gland acini were compared between the two groups.

Results:

Meibomian gland loss was found in both groups, but the meiboscore was not significantly different between the two groups (0.35 ± 0.6 vs 0.41 ± 0.8,
t
= −0.314,
P
> .05). The number of meibomian gland ducts (25.85 ± 3.25 vs 23.23 ± 3.06,
t
= −3.437,
P
< .05), relative width of the meibomian gland ducts (69.62% ± 5% vs 66.1% ± 7%,
t
= −2.454,
P
< .05), and percent area of the meibomian gland acini (57.7% ± 4% vs 55.5% ± 4%,
t
= 2.571,
P
< .05) in the upper eyelid were significantly greater in adolescents than in children. However, no significant differences were found in the lower eyelid between the two groups.

Conclusions:
Meibography is useful for the assessment of ocular surface conditions in children and adolescents. Meibomian gland loss occurs in both children and adolescents. The meibomian glands of the upper eyelid exhibit more morphological changes in adolescents than in children.

Examining the Factors that Facilitate Athletic Training Faculty Socialization into Higher Education
Authors: Mazerolle Stephanie M. , Barrett Jessica L. , Nottingham Sara 
Published: January 2017

Context: Doctoral education is the mechanism whereby athletic trainers can develop an awareness of their future roles and responsibilities in higher education. Evidence suggests that doctoral education may provide an incomplete understanding of these roles and responsibilities, warranting further investigation.Objective: To gain a better understanding on how athletic training faculty members are socialized into their role.Design: Qualitative study.Setting: Higher education institutions.Patients or Other Participants: Twenty-eight athletic training educators (14 men, 14 women) who had completed doctoral training. Participants' average age was 39 ± 6 years, with 11.6 ± 5.6 years of experience working in education.Main Outcome Measure(s): One-on-one interviews were completed with all participants following a semistructured framework. Data saturation drove sampling. Inductive analysis was used to evaluate the data. Member checks, peer review, and researcher triangulation established rigor.Results: The first theme, professional socialization, was defined by participants as those experiences in their doctoral training that provided role understanding. The second theme, organizational socialization, speaks to those experiences that occurred once the athletic training faculty member was employed full time in higher education. The category of mentorship was articulated, in both themes, as impactful in both professional preparations at the doctoral level and during the institutional socialization process once a novice faculty member is hired.Conclusions: Doctoral education provides the platform for role understanding, which allows the athletic trainer to be prepared to transition into the faculty member role. Specifically, engagement in the role and mentoring provided this role awareness, which is common within the socialization framework. Institutions also offer formalized orientation sessions as a means to assimilate, and mentoring is also available for support.
An Exploratory Study of Athletic Training Student Communication
Authors: Carr W. David , Volberding Jennifer L. , Timson Ben 
Published: January 2017

Context: Employers have reported that the ability to communicate is the greatest deficiency of new athletic training graduates. New graduates must be able to communicate effectively with a wide range of stakeholders to ensure the best health care of their patients. To date there have been no studies to determine which stakeholders the students are communicating with during clinical experiences.
Objective: To investigate the opportunity to communicate with various stakeholders by students during their clinical experiences.
Patients or Other Participants: Participants were 932 students (308 male, 624 female) from university athletic training programs.
Data Collection and Analysis: The study used an online survey instrument that allowed students to recall which stakeholders they had the opportunity to communicate with during the prior week of their clinical experiences. Basic descriptive statistics were calculated to describe the study sample and a χ2 contingency table analysis was used to determine significance. The dependent variables were stakeholders with whom they communicated (coach/clinic director, athlete/patient, parent, administrator, peer/colleague, and other health care professional) and the independent variables were demographics (sex, athletic affiliation of host institution, state/private affiliation of host institution, entry-level degree, year in program, clinical rotation setting, and athletic affiliation of clinical rotation).
Results: Year in program indicated a significant correlation with all of the dependent variables, with Cramer V ranging from 0.098 to 0.157. The highest significant correlation was found between clinical rotation setting and communication with parents (Cramer V = 0.418).
Conclusions: As one would expect, as students matriculate and gain higher levels of maturity, they report more opportunities to communicate. Similarly, students in multisport secondary schools or lower-level collegiate clinical experiences report more opportunities to communicate.
An unusual sigmoid phytobezoar in a patient with a transplanted kidney: A case report
Authors: Milillo Paola , Moffa Angelo Pio , Bertozzi Vincenzo , Vinci Roberta , Macarini Luca 
Published: January 2017

AbstractBezoars are masses formed by the concretion of stomach contents or debris within the gastrointestinal tract. Bezoars are rare and account for only 0.4–4% of all cases of gastrointestinal obstruction and mainly occur in the stomach or small intestine. Intestinal obstruction caused by colonic bezoars is extremely rare. A 39-year-old man with a transplanted kidney came to the hospital because of abdominal pain, constipation, and distension. We performed an abdominal computed tomography scan and found an ovoid intraluminal mass with a mottled gas pattern in the distal sigmoid colon. Subsequently, the patient underwent laparotomic surgery and removal of the bezoar. We report a rare case of large bowel obstruction due to colonic phytobezoar, which was confirmed intraoperatively.

Abstract
Background: Trochlear dysplasia is the most commonly encountered congenital etiologic factor of anterior knee pain. Aims: The purpose of this study was to evaluate the relationship between trochlear dysplasia with medial patellar plica as well as to investigate the distribution of plica types according to types of dysplasia. Settings and Design: This is a retrospective case-control study. Materials and Methods: This study was conducted among 138 knee magnetic resonance imaging (MRI) scans. The presence of medial plica and its types were compared among 69 patients in whom trochlear dysplasia had been detected and 69 individuals with normal trochlear who were of the same age and gender as the patient group. Statistical Analysis: Trochlear dysplasia and medial plica was compared by Chi-square with Yates correction and Fisher's exact probability tests (P < 0.001). The data were presented as mean, standard deviation, minimum–maximum, frequency, and percentage. Results: Of all the patients (n = 138), the number of patients in whom plica was observed was n = 104 (75.3%), and the distribution of plica type was as follows: n = 70 (67.3%) Type 1, n = 25 (24%) Type 2, and n = 9 (8.6%) Type 3. Medial plica was more frequently observed in patients with trochlear dysplasia (P < 0.001). Type 2 and Type 3 medial plica were more frequently encountered in trochlear dysplasia (P < 0.001). Type 3 plica was not seen in patients with normal trochlea. Conclusion: Medial patellar plica is more frequently seen in trochlear dysplasia. As the type of trochlear dysplasia progresses, the prevalence of thicker and shelf-shaped plica increases.
Myelopathy in adult aortic coarctation: Causes and caveats of an atypical presentation
Authors: Mourya Chandan , Verma Ashish , Bansal Anand , Shukla Ram C , Srivastava Arvind 
Published: January 2017

AbstractA 57-year-old female presenting with acute-onset paraplegia was referred for magnetic resonance imaging (MRI) of cervico-dorsal spine. On MRI, multiple tortuous dilated vessels were noted in the epidural space with long segment cord compression and imaging features of compressive myelopathy. Associated small acute cervico-dorsal epidural hematoma was also noted in the same region. Computed tomography (CT) angiography was performed subsequently which revealed post-ductal coarctation of aorta with multiple arterial collaterals in the chest wall and spinal canal. An extensive review of English language literature pertaining to the clinical presentations of adult aortic coarctation revealed only few reports of acute compressive myelopathy due to spinal epidural collateral vessels. Further, presentation at such a late age has not been reported before. In the present case, apart from a hypertrophied anterior spinal artery and perispinal collaterals, an anterior epidural hematoma was an additional important factor in the causation of myelopathy.

Published: January 2017

AbstractLymphatic malformations are congenital vascular malformations with lymphatic differentiation. Although the most common locations for lymphatic malformation are the neck and axilla, they can occur at several locations in the body including the abdomen. The abdominal location is rather rare and accounts for approximately 5% of all lymphatic malformation. Abdominal lymphatic malformation can arise from mesentery, omentum, gastrointestinal tract, and retroperitoneum. Clinical presentation includes an abdominal lump, vague abdominal discomfort, and secondary complications including intestinal obstruction, volvulus, ischemia, and bleeding. There is a broad spectrum of radiological manifestation. In the present review, we discuss the imaging appearance of abdominal lymphatic malformation. The diagnosis of lymphatic malformation in our series was based on the histopathological examination (in cases who underwent surgery) and fine needle aspiration cytology.
Percutaneous epidural drainage through a burr hole
Authors: Falsarella Priscila M , Rocha Rafael D , Garcia Rodrigo G 
Published: January 2017

AbstractIntracranial extradural collection may cause an increase in intracranial pressure, requiring rapid emergency treatment to reduce morbidity and mortality. We described an alternative CT-guided percutaneous access for extradural collection drainage. We report a case of a patient with previous craniectomy for meningioma ressection who presented to the Emergency Department with symptoms of intracranial hypertension. Brains CT showed a extradural collection with subfalcine herniation. After multidisciplinary discussion a CT-guided percutaneous drainage through previous burr hole was performed. The patient was discharged after 36 hours of admission, without further symptoms. We describe a safe and effective alternative percutaneous access for extradural collection drainage in patients with previous burr hole.
Neurotuberculosis immune reconstitution inflammatory syndrome in the setting of HIV infection: A case report and review of literature
Authors: Jaganmohan Deepasree , Chakkalakkoombil Sunitha V , Beena Anjana A , Krishnan Nagarajan 
Published: January 2017

AbstractImmune reconstitution inflammatory syndrome (IRIS) is an exaggerated immune response which can occur with various coinfections in human immunodeficiency virus (HIV) infected patients, of which the most commonly implicated in central nervous system (CNS)-IRIS are progressive multifocal leukoencephalopathy (PML), cryptococcosis, and tuberculosis (TB). TB-IRIS is a known complication of pulmonary TB or TB lymphadenitis coinfection in HIV infected patients who are on antituberculosis treatment (ATT) after the initiation of antiretroviral therapy (ART). However, development of IRIS in extrapulmonary TB such as CNS TB is very rare. Our case is that of an isolated CNS-TB-IRIS, presenting as increase in the size and perilesional edema of the ring enhancing lesions in the brain, which was observed in two sequential magnetic resonance imaging done over a period of 2 months in a retropositive patient who presented with clinical deterioration after commencement of ART. As prompt diagnosis was made and specific management aimed at IRIS was started without delay, the patient improved symptomatically.
