TL;DR: This study confirms the good clinical and radiological results reported in the literature and indicates the trend towards improvements over time requires confirmation by longer-term studies, which will also have to establish that the increased wasting of the upper subscapularis muscle and fatty degeneration of the muscle belly have no adverse effects.
Abstract: Until the introduction of arthroscopic-assisted surgery for rotator cuff repair, the frequency of subscapularis tears was underestimated. These tears remain challenging to treat even with arthroscopy. The absence of a specific classification system has hampered communication about the treatment and outcomes of the various types of subscapularis tears. The objective of this prospective multicentre study was to validate the relevance of arthroscopic subscapularis tendon repair based on an assessment of short-term outcomes according to the initial extent of the anatomic lesions. A prospective multicentre study sponsored by the French Society for Arthroscopy was conducted from March 2010 to January 2011 in 208 patients with subscapularis lesions that were either isolated or associated with limited anterosuperior tears. The Constant and UCLA scores were used to assess clinical outcomes. Anatomic and prognostic results were evaluated based on the physical examination, preoperative and postoperative imaging study findings, and anatomic lesions. Clinical data were available for 103 patients after at least 1 year of follow-up and radiological data for 129 patients after at least 6 months. Our study confirms the good clinical and radiological results reported in the literature. Our classification system distinguishing four lesion patterns was applicable during the imaging workup. The main finding from this classification system was the difference in results between Type 2 and Type 3 lesions. The trend towards improvements over time requires confirmation by longer-term studies, which will also have to establish that the increased wasting of the upper subscapularis muscle and fatty degeneration of the muscle belly have no adverse effects.

TL;DR: Limited uterine artery embolization using large microspheres has good clinical success rate with low postprocedural pain and complications and women can expect excellent midterm results with a high level of symptom control and significant fibroid volume reduction.
Abstract: Purpose: A French multicenter registry was set up to confirm the safety and efficacy of large calibrated tris-acryl gelatin microspheres for embolization of symptomatic fibroids Methods: Technical recommendations included embolization using large microspheres (>500 µm) with no secondary embolization agent Postprocedural pain, clinical improvement and adverse events were prospectively evaluated during a follow-up period of at least 6 months Results: Eighty-five women complaining of fibroid-related symptoms entered the study In seven women, a secondary embolization agent was used in addition to microspheres Complete resolution of menorrhagia was achieved in 84% of women at 24 months and significant uterine and fibroid volume reductions were noted after 6 months (37% and 73%, respectively) Three women experienced definitive amenorrhea (4%) and two women required hysteroscopic resection of a fibroid Eight women were treated by hysterectomy because of treatment failure In seven of these women, treatment failure was explained by an additional cause of symptoms including diffuse adenomyosis, endometrial hyperplasia or ovarian artery supply to the fibroids Conclusion: Limited uterine artery embolization using large microspheres has good clinical success rate with low postprocedural pain and complications Women can expect excellent midterm results with a high level of symptom control and significant fibroid volume reduction Confidence in the end-point recommended here may require the experience of several cases

TL;DR: In this article, the authors used the capacities of a computer and the knowledge about the count fluctuations to perform an automated comparison of the images, which can be used to detect the changes between two images.
Abstract: The detection and visualisation of the changes between two images is the basis or the goal of several imaging techniques. Thus, digitized subtraction angiography consists in visualizing the differences between two images obtained without and with iodine contrast, intravenously injected. In Nuclear Medicine, the comparison of two scintigraphic images of the same organ explored under varying conditions (images acquired at different times, with different tracers, after various physiological or pharmacological interventions) is a routine problem. The visual comparison of the images is often a difficult task for the following reasons: The differences can be too low to be visually identified. In certain types of images, there are normal statistical fluctuations which can mask or simulate a difference. The gray level intensities can be different in the images which must be first normalized. Therefore, it seems reasonable to use the capacities of a computer and the knowledge about the count fluctuations to perform an automated comparison of the images. Better performances than those given by the visual inspection can be expected from such a procedure. To form this comparison, it is necessary to first register the images (alignment, normalization, magnification,…) (1,2,3,4,5) and second detect the changes by analyzing the images point by point (6,7).

TL;DR: This standardized CT scan analysis after Latarjet procedure has shown to accurately describe graft positioning in the axial plane with both good intra-observer reproducibility and inter-ob server reproducible.
Abstract: The success of shoulder stabilization with the Latarjet procedure depends on the correct positioning of the coracoid graft at the glenoid. The aim of this study was to assess intra-observer reproducibility and inter-observer reproducibility of a new standardized CT scan analysis for coracoid graft positioning in the axial plane after the Latarjet procedure and to assess the positioning in the study group. A consecutive series of 27 patients (22 men, 5 woman, 26.1 ± 6.4 years—13 right, 14 left shoulders) were followed up with CT scans between 2010 and 2012. The analysis of the CT scans (2.4 ± 0.7 months postoperatively) was performed with Osirix™ software. The assessment included two criteria in the axial plane: relation of the graft to the articular surface of the glenoid and impingement of the graft with the maximal humeral head circumference. Grafts were judged to be lateral, congruent, flush or medial. The strength of intra-observer agreement and inter-observer agreement was measured by the Kappa coefficient. The Kappa coefficient for intra-observer agreement was “substantial” (K = 0.64 ± 0.14, z = 4.6) to “almost perfect” (K = 0.81 ± 0.14, z = 5.7). The Kappa coefficient for inter-observer variability was “substantial” (K = 0.59 ± 0.14, z = 4.3) to “almost perfect” (K = 0.89 ± 0.14, z = 6.0). In our study, in the axial plane, 3 (11 %) transplants were lateral; 6 (22 %) transplants were congruent; 16 (60 %) flush and 2 (7 %) medial. This standardized CT scan analysis after Latarjet procedure has shown to accurately describe graft positioning in the axial plane with both good intra-observer reproducibility and inter-observer reproducibility. Case series, treatment study, Level IV.

TL;DR: The results imply that Se supplementation does not lead to a general protection during infection, but may help protect the heart from inflammatory damage, as indicated by a lower cardiac isoform of creatine kinase levels.
Abstract: Chagasic patients with cardiomyopathy have low levels of selenium (Se), a fundamental trace element We evaluated the effect of supplementing infected mice with Se (025-16 ppm) Supplementation with 025 or 1 ppm Se led to parasitaemia and survival curves similar to those of the control group Mice treated with 4-16 ppm showed a dose-dependent decrease of parasitaemia, significant for the highest concentration This was probably due to a direct effect on the parasites, which were lysed after in vitro incubation with Se Survival rates did not change significantly; however, heart damage was reduced in infected mice supplemented with 4 ppm Se, as indicated by a lower cardiac isoform of creatine kinase levels Our results imply that Se supplementation does not lead to a general protection during infection, but may help protect the heart from inflammatory damage The effect of Se supplementation in the course of T cruzi infection depends on the host-parasite pair employed
