Modified percutaneous repair of ruptured Achilles tendon.

Abstract: Percutaneous repair of the Achilles tendon is now well established. Sural nerve injury is one of the commonest complications following this method of repair. We present our current method of percutaneous repair which permits a less invasive approach to the tendon, accurate opposition of the tendon ends, and minimises the chance of sural nerve injury.

Epidemiology, genetics and biological factors of rotator cuff tears.

Abstract: Rotator cuff disease is among the most common musculoskeletal disorders with high direct and indirect costs in industrialized countries. Not all rotator cuff tears are symptomatic. Genetics has recently been investigated as a factor involved in the pathogenesis of rotator cuff pathology. Genetic factors seem to be involved in symptom presentation and tear progression. As rotator cuff disease is multifactorial, no single gene is directly involved in the pathology. Phenotypic expression of genetic susceptibility manifests at the level of ultrastructure of the tendon. Predisposing genes may also operate through apoptosis and regenerative capacity. Studies on cellular and molecular biology are more numerous, but still incomplete, and recently have focussed on the role of apoptosis in tendinopathy, analyzing its key mediators and cellular changes. Oxidative stress is responsible for reduction of collagen synthesis. Biological investigations have identified recently new risk factors. Preliminary reports introduced the possible role of glucose as a risk factor for rotator cuff tear. Further studies are required to fully clarify the genetic and biological factors involved in rotator cuff tears.

Oxygen species and overuse tendinopathy in athletes

Abstract: Purpose. To review the current concepts on tendon damage and reactive oxygen species (ROS). We suggest that tendons are subject to reactive oxygen generated both within the vicinity of the tendon and from the tenocytes themselves. Method. A literature search was conducted to trace relevant literature on tendon damage and ROS. Results. Tendinopathies have a complex aetiology. Tendon physiology and structure may preclude ROS involvement in various aspects of the predisposition to and participation in a failed healing response process and subsequent response to injury. However, given the ubiquitous nature of ROS production and their now accepted involvement in signal transduction, such highly active chemicals may influence signal transduction in the tendon. Therefore, the tendon is continually exposed to ROS during normal and athletic exercise which, in combination with lifestyle and possibly hereditary factors, may influence tendon integrity and orchestrate tendon repair. Conclusions. The production of ROS by tenocytes may be a response to hyperthermia and to repetitive ischaemia/ reperfusion, and may influence the development of tendinopathies.

Higher fasting plasma glucose levels within the normoglycaemic range and rotator cuff tears

Abstract: Objective: To determine the plasma glucose levels in non-diabetic patients with rotator cuff tear. Design: Frequency-matched case–control study. Setting: University Teaching Hospital. Participants: The study included 194 subjects who were operated on at our institution. Group 1 included 97 consecutive patients (36 men and 61 women; mean age: 62.9 years, range 37 to 82) who underwent arthroscopic repair of a rotator cuff tear in 2007 and 2008. Group 2 (control group) included 97 patients (36 men and 61 women; mean age: 61.6 years, range 36 to 80) who underwent arthroscopic meniscectomy for a meniscal tear in the same period, and had no evidence of shoulder pathology. These patients were frequency-matched by age (within 3 years) and gender with patients of Group 1. Main outcome measure: Measurement of fasting plasma glucose levels. Results: Patients with rotator cuff tears (Group 1) showed statistically significantly higher fasting plasma glucose levels within the normoglycaemic range (p = 0.007) than patients with meniscal tear (Group 2). Conclusions: The present study suggests that normal, but in the high range of normal, increasing plasma glucose levels may be a risk factor for rotator cuff tear. An enhanced understanding of these factors holds the promise of new approaches to the prevention and management of rotator cuff tears.

I and i

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 …

Standards of Medical Care in Diabetes

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.

Harrison's Principles of Internal Medicine

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
