Published: November 2016

Materials and methods. The authors studied gait biomechanics in respect of time, velocity and dynamics in 34 patients with verified ACL rupture including 11 patients (first group) before the surgery and 23 patients (second group) after the surgery. Patients of the first group were followed in the period from 1 week up to 6 years (mean – 18 months), of the second group – from 1.5 months up to 5.5 years (mean – 13 months). Patients of the second group underwent standard arthroscopic ACL reconstruction with semitendinous and gracillis tendon autograft. Biomechanical gait examination was performed using strap down inertial motion sensors that register rotation angles in space. The authors measured time phases of gait cycle, movements in hip and knee joints in three mutually perpendicular planes as well as walking shock load.Results. Time phases of gait cycle in both groups demonstrated normal values both on healthy and affected limbs. Movements in hip and knee joints were within the normal range, no reliable differences in the analogous indices for each limb were reported. Shock load in walking was registered within 1.6 g, symmetrical on both sides; shock load dynamics was absent in the group of patients after the surgery. Study results did not identify functional disorders during random flat surface waking that would be specific for ACL lesion as compared to normal values and to intact limb. However, a certain tendency was observed towards an increase of flexion-extension movement range in the knees following ACL reconstruction. The reported differences were not credible.Conclusion. The authors did not observe any specific functional knee joint instability during normal activities in the first group of patients with ACL rupture. On the one hand, that means that ACL lesion does not manifest in such circumstances, on the other - knee joint instability does not progress during flat surface walking at a random pace. The obtained results give certain ground to reconsider the concept of “knee joint instability”.

Introduction. Currently flexible intramedullary nailing (FIN) is the method of choice for treatment of diaphyseal forearm fractures in children.Purpose of the study: to perform a quantitative and qualitative analysis of failures and complications encountered in treatment of children with diaphyseal forearm fractures using FIN fixation.Materials and methods. The study included 55 consecutive continuous cases of diaphyseal forearm fractures in children operated by FIN fixation from October 2011 till October 2014. Follow up period covered timeframe from admission until implant removal but no less than 6 months. The authors studied age, gender, fracture pattern, surgical technique features, length of hospital stay, frequency of outpatient examinations, healing period, x-ray data and all complications.Results. Complications during treatment were reported in 10 patients. Two patients demonstrated two complications. In two cases a surgical procedure was required to address the complications. Early postoperative complications were observed in two cases (neuropathy of superficial branch of radial nerve). In other cases patients developed complications at outpatient stage starting one to six months after the surgery which did not impact the final outcome.Conclusion. Despite various complications observed following FIN fixation of diaphyseal forearm fractures in children, their severity and frequency had no impact on the final outcome in the authors’ case series. Majority of issues were related to violations in surgical technique and adverse fracture pattern.

Published: November 2016

Purpose: to identify anatomical landmarks on tibial articular surface to serve as reference in preparing tibial canal with respect to the center of ACL footprint during single bundle arthroscopic repair.Materials and methods. Twelve frozen knee joint specimens and 68 unpaired macerated human tibia were studied using anatomical, morphometric, statistical methods as well as graphic simulation.Results. Center of the tibial ACL footprint was located 13,1±1,7 mm anteriorly from posterior border of intercondylar eminence, at 1/3 of the distance along the line connecting apexes of internal and external tubercles and 6,1±0,5 mm anteriorly along the perpendicular raised to this point.Conclusion. Internal and external tubercles, as well as posterior border of intercondylar eminence can be considered as anatomical references to determine the center of the tibial ACL footprint and to prepare bone canals for anatomic ligament repair.

Published: November 2016

OBJECTIVE
To examine whether cardiovascular autonomic neuropathy (CAN) is an independent risk factor of cardiovascular disease (CVD) events during DCCT/EDIC.

RESEARCH DESIGN AND METHODS
Standardized cardiovascular autonomic reflex tests (R-R response to paced breathing, Valsalva maneuver, postural changes in blood pressure) were performed at DCCT baseline, every 2 years throughout DCCT, and at two time points in EDIC. CVD events were ascertained throughout the study and adjudicated by a review committee. Cox proportional hazards models were used to estimate the effect of CAN at DCCT closeout on subsequent CVD risk.

RESULTS
There were 299 adjudicated CVD events in 165 participants following the DCCT closeout assessment: 132 of 1,262 subjects (10%) without CAN at DCCT closeout who experienced 244 CVD events versus 33 of 131 subjects (25%) with CAN at DCCT closeout who experienced 55 events (hazard ratio 2.79, 95% CI 1.91–4.09 for time to first CVD event). The cumulative incidence of the first occurrence of any CVD event during EDIC was significantly higher in participants with CAN at DCCT closeout compared with those without CAN. The association remained marginally significant after adjustment for multiple risk factors, including the EDIC updated mean HbA1c. When analyzed as a continuous variable, R-R variation was significantly lower at DCCT closeout in participants who experienced a CVD event compared with those who did not (P = 0.0012).

CONCLUSIONS
In the DCCT/EDIC cohort, individuals diagnosed with CAN at DCCT closeout experienced a higher long-term risk of CVD events during follow-up in EDIC. This association was not independent of historic glycemic exposure and its metabolic memory effect, the principal determinant of both long-term CVD risk and CAN in type 1 diabetes.

Authors: Schmalz G , Hellwig F , Mausberg RF , Schneider H , Krause F , Haak R , Ziebolz D 
Published: November 2016

SUMMARY
Objective: The aim of this study was to investigate dentin protection of different desensitizing varnishes (light- and self-curing) during acid action/abrasion stress and thermocyclic loading in vitro.
Methods: Dentin discs of 2 mm thickness were cut from 120 human molars, embedded, and polished. Specimens were randomized into five groups (n=24): A, negative control; B, Gluma Desensitizer; C, Cervitec plus (self-curing); D, Seal&Protect; and E, Admira Protect (light-curing). In groups B-E, varnish was applied on two-thirds of the dentin surface, and one-third acted as internal control. Stress cycle (2 cycles/day) for specimens were as follows: 1, acid action (pH: 2.9: five minutes); 2, remineralization (synthetic saliva: 60 minutes); 3, brushing (100 strokes); 4, thermocycling (five cycles); and 5, remineralization (synthetic saliva: six hours) for each group (n=12) for 30 (15 days) or 60 times (30 days). Specimens were analyzed using an incident light microscope. Substance loss was measured in micrometers. Statistical analysis was performed with the multiple contrast test (p&lt;0.05).
Results: Groups B and C had a significantly lower dentin loss than A (p&lt;0.01). After 30 days, group A showed the highest dentin loss (p&lt;0.01), whereas the other groups lacked a significant difference regarding their substance loss (dentin and/or varnish; p&gt;0.05). Varnish layer loss was shown for groups D and E with a remaining protective layer; groups A-C showed dentin removal.
Conclusion: All four varnishes are protective compared with an untreated control. Light-curing varnishes might provide higher dentin protection than self-curing materials.

Published: November 2016

Abstract
OBJECTIVE To identify and evaluate 3 types of angiographic catheters for retrograde urinary bladder catheterization in healthy male goats.
ANIMALS 12 sexually intact yearling Alpine-cross bucks.
PROCEDURES Three 5F angiographic catheters of the same length (100 cm) and diameter (0.17 cm) but differing in curvature at the tip were labeled A (straight tip), B (tip bent in 1 place), and C (tip bent in 2 places). During a single anesthetic episode, attempts were made to blindly pass each catheter into the urinary bladder of each goat. Order of catheters used was randomized, and the veterinarian passing the catheter was blinded as to catheter identity. The total number of attempts at catheter passage and the total number of successful attempts were recorded.
RESULTS Catheter A was unsuccessfully passed in all 12 goats, catheter B was successfully passed in 8 goats, and catheter C was successfully passed in 4 goats. The success rate for catheter B was significantly greater than that for catheter A; however, no significant difference was identified between catheters B and C or catheters A and C.
CONCLUSIONS AND CLINICAL RELEVANCE 2 angiographic catheters were identified that could be successfully, blindly advanced in a retrograde direction into the urinary bladder of healthy sexually intact male goats. Such catheters may be useful for determining urethral patency, emptying the urinary bladder, and instilling chemolysing agents in goats with clinical obstructive urolithiasis.
Discord Between Approaches to Spinal and Extremity Disorders: Is It Logical?
Authors: Jull Gwendolen 
Published: November 2016

Rapid advances in the basic, clinical, and behavioral sciences are molding developments in conservative management of musculoskeletal disorders. Curiously, there seems to be discord developing between approaches to the assessment and management of patients, depending on whether they present with an extremity or spinal disorder. This viewpoint will comment on examples of differences emerging in some current practices. The aim is not to present a scientific treatise about underpinning sciences and evidence-based practice or to comment on what is correct or incorrect. Rather, the aim is to stimulate thought on the seeming discord in clinical practice, with respect to both the clinical evaluation of, as well as management approaches to, extremity and spinal disorders.

Study Design Cross-sectional study. Background Functional task performance in patients with chondrolabral pathology following hip arthroscopy is unknown. Objectives To investigate in people with chondrolabral pathology following hip arthroscopy (1) the bilateral differences in functional task performance compared to controls, (2) the association of hip muscle strength with functional task performance, and (3) the association of functional task performance scores with good outcome, as measured by International Hip Outcome Tool score. Methods Seventy-one patients who had unilateral hip arthroscopy for hip pain and 60 controls were recruited. Patient-reported outcomes included the 4 subscales of the International Hip Outcome Tool. Hip muscle strength measures included abduction, adduction, extension, flexion, external rotation, and internal rotation. Functional tasks assessed included the single hop test, the side bridge test, and the single-leg rise test. For aim 1, analyses of covariance tests were used. For aim 2, stepwise multiple linear regression analyses were used. For aim 3, receiver operating characteristic curve analyses were used. Results Compared to controls, the chondrolabral pathology group had significantly worse performance on both legs for each of the functional tasks (P<.001). Greater hip abduction strength was moderately associated with better performance on functional tasks in the chondrolabral pathology group (adjusted R2 range, 0.197–0.407; P<.001). Cutoff values associated with good outcome were 0.37 (hop distance/height) for the single hop, 16 repetitions for the single-leg rise, and 34 seconds for the side bridge test. Conclusion Patients with hip chondrolabral pathology had reduced functional task performance bilaterally 12 to 24 months after unilateral hip arthroscopy when compared to controls.

Synthesis and properties evaluation of β-SiAlON prepared by mechanical alloying followed by different sintering technique
Authors: Nekouee Khan Ali , Khosroshahi Rasoul Azari 
Published: November 2016

Abstract
In this study, sintering was investigated for making SiAlON by utilizing low cost Si3N4, Al2O3 and AlN powder precursors. These materials were mixed by mechanical ball milling, then processed by pressureless sintering or spark plasma sintering methods and the properties compared. XRD spectroscopy showed nano-scale and amorphous phases, which were produced after longer milling time. Investigation of the bulks after sintering revealed that increasing the pressureless sintering temperature resulted in an increase in density and mechanical properties of the specimens, as did changing the sintering technique from pressureless to spark plasma sintering. Furthermore, the wear mechanisms of adhesive or micro-abrasion of the rubbed surfaces were confirmed.
Metallographic Preparation of Hard Coatings for EBSD Analysis
Authors: Ramos-Moore E. 
Published: November 2016

Abstract
Metallographic preparation is an art, especially when relevant information hidden at the micro- or nano-scale has to be unraveled. In particular, electron backscattered diffraction (EBSD) is a technique that provides valuable information of the microstructure of bulk and coatings. Indeed, information regarding evolution of the morphology, size and orientation of grains is very relevant for the design and fabrication of new commercial coatings. Metallographic preparation for EBSD analysis of hard coatings consisting of Al2O3 and TiCN layers is presented in this work. In particular, preparation timing during grinding and polishing is discussed. EBSD data is presented and correlated with the metallographic preparation parameters. The main conclusions of this work highlight the importance of systematic preparation of all the successive metallographic procedures and the understanding of the quality parameters associated with the EBSD scans and data processing.
Marine Bryozoa of Greece: an annotated checklist
Authors: Gerovasileiou Vasilis , Rosso Antonietta 
Published: November 2016

Until today, a complete checklist of Bryozoa of the Greek seas had never been published and species records were scattered in several taxonomic and ecological studies. The aim of this paper is to produce a first checklist of marine bryozoan species of Greece, in the framework of the Greek Taxon Information System (GTIS) initiative of the LifeWatchGreece Research Infrastructure (ESFRI), by reviewing the existing literature and following the recent trends in the taxonomy of this group. ﻿
The marine bryozoan fauna of Greece comprises 237 species, classified in 127 genera, 66 families, 3 orders, and 2 classes. The vast majority belongs to the class Gymnolaemata (177 Cheilostomatida and 21 Ctenostomatida), while the remaining 39 species are Stenolaemata (all Cyclostomatida). Among these species, 12 are considered endemic to the eastern Mediterranean, while another 12 species are non-indigenous.

Published: November 2016

The checklist of Porifera of Greece was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of species recorded from Greece. An updated checklist of Porifera was created on the basis of a list of the Aegean Demospongiae and Homoscleromorpha published one decade ago. All records of species known to occur in Greek waters were taxonomically validated and cross-checked for possible inaccuracies and omissions. Then, all recent publications were reviewed and the species recorded from 2006 to date were added to the list.
The updated checklist of Porifera of Greece comprises 215 species, classified to 111 genera, 65 families, 24 orders, and 4 classes. In total, 34 new additions were made to the previous species list (8 Calcarea, 17 Demospongiae, 1 Hexactinellida, and 6 Homoscleromorpha) with Calcarea being listed for the first time from the area. The demosponge orders Poecilosclerida, Dictyoceratida, Tetractinellida, Haplosclerida, and Suberitida have the highest number of species covering 62% of the known Greek sponge species richness. It is worth mentioning that 8 species have been first described from Greek waters, 7 of which are considered endemic to this area. Our bibliographic overview also revealed knowledge gaps with regard to specific habitats typically rich in sponge diversity, and marine sectors of Greece.

Published: November 2016

The checklist of the ascidian fauna (Tunicata: Ascidiacea) of Greece was compiled within the framework of the Greek Taxon Information System (GTIS), an application of the LifeWatchGreece Research Infrastructure (ESFRI) aiming to produce a complete checklist of species recorded from Greece. This checklist was constructed by updating an existing one with the inclusion of recently published records. All the reported species from Greek waters were taxonomically revised and cross-checked with the Ascidiacea World Database.
The updated checklist of the class Ascidiacea of Greece comprises 75 species, classified in 33 genera, 12 families, and 3 orders. In total, 8 species have been added to the previous species list (4 Aplousobranchia, 2 Phlebobranchia, and 2 Stolidobranchia). Aplousobranchia was the most speciose order, followed by Stolidobranchia. Most species belonged to the families Didemnidae, Polyclinidae, Pyuridae, Ascidiidae, and Styelidae; these 4 families comprise 76% of the Greek ascidian species richness. The present effort revealed the limited taxonomic research effort devoted to the ascidian fauna of Greece, which is attributed to the lack of experts and low sampling effort. Therefore, major knowledge gaps on the ascidian diversity of Greece occur and further research in this field is needed.
Subclinical Synovitis Assessed by Ultrasound Predicts Flare and Progressive Bone Erosion in Rheumatoid Arthritis Patients with Clinical Remission: A Systematic Review and Metaanalysis

Published: November 2016

Objective.Subclinical synovitis can be detected by ultrasound in patients with rheumatoid arthritis (RA) who are in clinical remission. We aimed to confirm its predictive value for flare and progressive bone erosion.Methods.A systematic literature search was performed in Pubmed, Web of Science, Embase, and Cochrane Library on September 7, 2014. Baseline clinical and ultrasonographic characteristics were collected. Methodological quality was assessed. Pooled OR were calculated using Mantel-Haenszel model. We explored the source of heterogeneity through subgroup analysis and completed a cumulative metaanalysis.Results.Thirteen articles were included (8 with flare, 4 with bone erosion, 1 with both flare and bone erosion). Metaanalysis revealed an association between power Doppler (PD) positivity and the risk of flare (OR 4.52, 95% CI 2.61–7.84, p < 0.00001, I2 = 21%), the risk of progressive bone erosion on patient level (OR 12.80, 95% CI 1.29–126.81, p = 0.03, I2 = 52%) and the risk of progressive bone erosion on joint level (OR 11.85, 95% CI 5.01–28.03, p < 0.00001, I2 = 0%). Further subgroup analysis showed a higher risk of flare in patients with a study period < 1 year (OR 19.98 vs 3.41). No significant differences were observed in the subgroup analysis in duration of remission, disease duration, and medications. Moreover, cumulative metaanalysis indicated the validation and an increasing accuracy of PD positivity in predicting flare since 2012.Conclusion.Ultrasound-detected subclinical synovitis can predict the risk of flare and progressive bone erosion in RA patients with clinical remission. Additionally, the flare of RA tends to occur within a followup of 1 year.
