TL;DR: There is a need for a validated reproducible method of rotator cuff tendon biopsy evaluation and further studies with improved designs are required to effectively evaluate the histological and immunohistochemical features of rotators cuff tendinopathy.
Abstract: Background Rotator cuff tendinopathy is a common musculoskeletal ailment in sedentary and athletic individuals. Various mediators of inflammation have been detected in human tendons: they are thought to initiate or progress the course of tendinopathy. Sources of data An online search was conducted using AMED, CINAHL, Embase, The Cochrane Library, PEDro and Pubmed, using the terms tendinopathy, tendon, tendinitis, tendinosis, histology, histopathology, immunohistochemistry, immunohistochemical, rotator cuff and pain. Areas of agreement Histological examination of tendinopathic tendons shows degeneration of the collagen structure and infiltration of fat and vessels, together with increased expression of inflammatory cytokines, MMP-1, 2, 3, 9, 13, vascular endothelial growth factor and Hypoxia inducible factor (HIF). Areas of controversy Most of the studies about this topic exhibited limited validity because of lack of appropriately matched controls and no inclusion or exclusion criteria. The evidence associated with the histopathological analysis of the rotator cuff is limited. Growing points The histochemical and immunohistochemical features of rotator cuff tendinopathy are still unclear. A thorough understanding of the vascularity, innervation and biochemical mediators of pain could be used to target rotator cuff pathology, and possibly guide the therapy of painful rotator cuff disorders. Areas timely for developing research There is a need for a validated reproducible method of rotator cuff tendon biopsy evaluation. We require further studies with improved designs to effectively evaluate the histological and immunohistochemical features of rotator cuff tendinopathy.

TL;DR: Minimally invasive ipsilateral PB transfer and free ipsilaterally semitendinosus tendon graft with or without interference screw fixation are safe and effective procedures to reconstruct the Achilles tendon after a re-rupture, providing a significant improvement of the symptoms and function in the mid term.
Abstract: Purpose The purpose of this study was to compare outcomes of different minimally invasive techniques for reconstruction of Achilles tendon re-ruptures. Methods We prospectively enrolled 21 patients undergoing minimally invasive reconstruction using a transfer of the ipsilateral peroneus brevis (PB) (five patients) or the free ipsilateral semitendinosus tendon (ST) graft with or without interference screw fixation (ten and six patients, respectively). We assessed the maximum calf circumference and isometric plantar flexion strength before surgery and at the last follow up. TheAchillestendontotalrupturescore(ATRS)andnumberof single-leg heel lifts on the affected leg were evaluated at the last follow up. The median follow up was 39 months. Results The outcome of surgery was excellent/good in 17 (81 %) of 21 patients. In the operated leg, the maximum calf circumference and isometric plantar flexion strength were significantly improved after surgery (P<0.0001). The average ATRS was 86 (range 79-92), and the average number of single-legged heel lifts was 33 (range 11–48). No further reruptures were recorded. Conclusions Minimally invasive ipsilateral PB transfer and free ipsilateral ST graft with or without interference screw fixation are safe and effective procedures to reconstruct the Achilles tendon after are-rupture,providinga significant improvement of the symptoms and function in the mid term.

TL;DR: Although the three scoring systems used to evaluate the patients showed significant correlation with each other, they failed to correlate to patients' satisfaction and emphasis should be placed on individual variables, rather than on global elbow ratings.
Abstract: AIM The aim of this study was to assess the functional outcome of patients who had undergone elbow arthroscopy, evaluating the correlation between three elbow scoring systems and the patients' subjective perception of satisfaction METHODS Fourteen patients who had undergone elbow arthroscopy were retrospective reviewed to evaluate the correlation between three elbow scoring systems and the patients' subjective perception of satisfaction at a mean follow-up time of 24 months (range 12-64 months). Two independent orthopedic surgeons evaluated all patients using three elbow scoring systems, a simple satisfaction question and a visual analogue scale. RESULTS The three scoring systems showed significant correlation with each other (P<0.05). There was no correlation between the results of the three scoring systems and patients' satisfaction: patients with the same level of satisfaction could perform differently at the scoring systems. CONCLUSION Although the three scoring systems used to evaluate the patients showed significant correlation with each other, they failed to correlate to patients' satisfaction. In reporting the results of arthroscopic elbow procedures, emphasis should be placed on individual variables, rather than on global elbow ratings. Further studies are needed to develop a single outcome evaluation system which is reliable, valid and sensitive to changes of clinical importance, which takes into account both patients' and physicians perspective, and which is short and practical to use.

TL;DR: For surgeons who advocate immediate loading or motion of a side-to-side tendon repair, a pulley, running locked, or simple eight suture technique appears to provide a larger safety margin compared with a vertical mattress suture techniques.
Abstract: Background: Side-to-side tenorrhaphy is increasingly used, but its mechanical performance has not been studied.
Methods: Two porcine flexor digitorum tendon segments of equal length (8 cm) and thickness (1 cm) were placed side by side. Eight tenorrhaphies (involving sixteen tendons) were performed with each of four suture techniques (running locked, simple eight, vertical mattress, and pulley suture). The resulting constructs underwent cyclic loading on a tensile testing machine, followed by monotonically increasing tensile load if failure during cyclic loading did not occur. Clamps secured the tendons on each side of the repair, and specimens were mounted vertically. Cyclic loading varied between 15 N and 35 N, with a distension rate of 1 mm/sec. Cyclic loading strength was determined by applying a force of 70 N. The cause of failure and tendon distension during loading were recorded.
Results: All failures occurred in the monotonic loading phase and resulted from tendon stripping. No suture or knot failure was observed. The mean loads resisted by the configurations ranged from 138 to 398 N. The mean load to failure, maximum load resisted prior to 1 cm of distension, and load resisted at 1 cm of distension were significantly lower for the vertical mattress suture group than for any of the other three groups (p < 0.031).
Conclusions: All four groups sustained loads well above the physiologic loads expected to occur in tendons in the foot and ankle (e.g., in tendon transfer for tibialis posterior tendon insufficiency). None of the four side-to-side configurations distended appreciably during the cyclic loading phase. The vertical mattress suture configuration appeared to be weaker than the other configurations.
Clinical Relevance: For surgeons who advocate immediate loading or motion of a side-to-side tendon repair, a pulley, running locked, or simple eight suture technique appears to provide a larger safety margin compared with a vertical mattress suture technique.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care.
Abstract: XI. STRATEGIES FOR IMPROVING DIABETES CARE D iabetes is a chronic illness that requires continuing medical care and patient self-management education to prevent acute complications and to reduce the risk of long-term complications. Diabetes care is complex and requires that many issues, beyond glycemic control, be addressed. A large body of evidence exists that supports a range of interventions to improve diabetes outcomes. These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care. While individual preferences, comorbidities, and other patient factors may require modification of goals, targets that are desirable for most patients with diabetes are provided. These standards are not intended to preclude more extensive evaluation and management of the patient by other specialists as needed. For more detailed information, refer to Bode (Ed.): Medical Management of Type 1 Diabetes (1), Burant (Ed): Medical Management of Type 2 Diabetes (2), and Klingensmith (Ed): Intensive Diabetes Management (3). The recommendations included are diagnostic and therapeutic actions that are known or believed to favorably affect health outcomes of patients with diabetes. A grading system (Table 1), developed by the American Diabetes Association (ADA) and modeled after existing methods, was utilized to clarify and codify the evidence that forms the basis for the recommendations. The level of evidence that supports each recommendation is listed after each recommendation using the letters A, B, C, or E.

TL;DR: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors.
Abstract: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many
