During the past 2 decades, the frequency of pectoralis major muscle injuries has increased in association with the increased popularity of bench press exercises. Injury of the pectoralis major can occur at the muscle origin, muscle belly, musculotendinous junction, intratendinous region, and/or humeral insertion-with or without bone avulsion. The extent of the tendon injury ranges from partial to complete tears. Treatment may be surgical or conservative, depending on the clinical scenario and anatomic characteristics of the injury...

EDITORIAL
Kari Chansky, Dragan Subotic, Nathan R Foster, Torsten Blum
BACKGROUND: Although survival analyses represent one of the cornerstones in oncology in general, some aspects of the reported survival data in lung cancer patients are still not fully elucidated. METHODS: After having defined several open questions, an evidence based approach was applied in order to answer these questions. Areas of interest were: (I) possible uncertainties in reported survival data; (II) survival surrogates; (III) recommended methods for evaluating progression free survival (PFS) as a surrogate endpoint in future datasets; (IV) postoperative lung cancer recurrence and survival...

Wrist ligaments are crucial structures for the maintenance of carpal stability. They are classified into extrinsic ligaments, connecting the carpus with the forearm bones or distal radioulnar ligaments, and intrinsic ligaments, entirely situated within the carpus. Lesions of intrinsic and extrinsic ligaments of the wrist have been demonstrated to occur largely, mostly in patients with history of trauma and carpal instability, or rheumatoid arthritis. Ultrasound allows for rapid, cost-effective, non-invasive and dynamic evaluation of the wrist, and may represent a valuable diagnostic tool...

BACKGROUND: Protruding ears represent the main abnormality of the external ear, which has required numerous anatomic and surgical studies. Most studies give attention to the absence of the antihelix as the anatomic defect responsible for the clinical deformity of the lateral aspect of the ear that leads to its anteversion. The reason for this study is the controversial origin of the fold of the antihelix within the auricle framework, a field of interest for aesthetic otoplasty. The current study examined the medial surface of the cartilaginous ear frame from cadaver specimens with right morphology to investigate the starting point of the fold of the antihelix...

BACKGROUND: Research across the formal, natural and social sciences has greatly expanded our knowledge about complex systems in recent decades, informing a broadly inclusive, cross-disciplinary conceptual framework referred to as Systems Thinking (ST). Its use in public health is rapidly increasing, although there remains a poor understanding of how these ideas have been imported, adapted and elaborated by public health research networks worldwide. METHOD: This review employed a mixed methods approach to narrate the development of ST in public health...

: Mammography-based screening has been a valuable imaging tool for the early detection of non-palpable lesions and has contributed to significant reduction in breast cancer associated mortality. However, the breast imaging community recognizes that mammography is not ideal, and in particular is inferior for women with dense breasts. Also, the 2-D projection of a 3-D organ results in tissue superposition contributing to false-positives. The sensitivity of mammography is breast-density dependent...

The lack of adequate access to opioids in India as analgesics and for agonist therapies, forces millions to live with severe unalleviated pain, or languish with suffering associated with drug dependence. Although India is a major opium exporter, the excessively prohibitive 1985 narcotics law formulated to control harmful use of drugs, impeded the availability and access to opioids for medical and scientific purposes. Amendment of this law in 2014 established a new national regulatory framework for improved access to essential opioid analgesics...

Navigating through space is fundamental to human nature and requires the ability to retrieve relevant information from the remote past. With the passage of time, some memories become generic, capturing only a sense of familiarity. Yet, others maintain precision, even when acquired decades ago. Understanding the dynamics of memory consolidation is a major challenge to neuroscientists. Using functional magnetic resonance imaging, we systematically examined the effects of time and spatial context on the neural representation of landmark recognition memory...

BACKGROUND: Generally, surgeons' perceptions of surgical safety are based on experience and institutional policy. Our recent pilot survey demonstrated that the acceptable duration of surgery and criteria for open conversion during laparoscopic cholecystectomy (LC) vary among workplaces. METHODS: A web-based survey was distributed to 554 expert LC surgeons in Japan, Korea, and Taiwan. The questionnaire covered LC experience, safety measures and recognition of landmarks, decision-making regarding conversion to open/partial cholecystectomy and the implications of this decision...

Jiao and Liu (Research Articles, 16 October 2015, aac4383) reported the crystal structure of the protein complex polycomb repressive complex 2 from Chaetomium thermophilum This landmark structure has brought invaluable insights into the activation mechanism of this essential methyltransferase. However, the analysis of the x-ray data discussed below suggests that the description of oncogenic H3K27M peptide binding to the active site is incorrect.

OBJECTIVE: To evaluate longitudinal patterns of response to standard of care (SOC) therapy in clinical trials for systemic lupus erythematosus (SLE) and identify characteristics that differentiate non-responders from persistent responders. METHODS: Data were obtained from the Collective Data Analysis Initiative of the Lupus Foundation of America on 147 patients treated with placebo plus SOC in two 52-week Phase II/III trials in moderately-to-severely active SLE patients without acute nephritis...

BACKGROUND: The direct oral anticoagulant (DOAC) dabigatran is a direct thrombin inhibitor. Its landmark trial, the RE-LY study, observed a trend towards a higher incidence of myocardial infarctions (MI) in dabigatran treated patients. Since then, it has been discussed whether dabigatran increases the risk of MI. OBJECTIVE: In this study, we aimed to assess platelet reactivity and platelet thrombin receptor expression in dabigatran-treated patients. METHODS: We conducted a cross-sectional study in 13 hospitalized patients with planned initiation of dabigatran medication...

Article Incorrect patient positioning and the resultant image distortion occur in many radiographic examinations. This study aimed to assess the effect of tilting, rotation and tipping of the head on the accuracy of maxillofacial transverse measurements made on cone beam computed tomography (CBCT) scans. The CBCT scans were obtained in central position of 10 dry human skulls. Using three-dimensional (3D) Dolphin software, six positions namely 10° and 20° tilts, rotations and tips were reconstructed of central position...

In this issue, the reader will find three articles examining different but converging perspectives on medically unexplained symptoms (MUS). In the first article, Gates, Petterson, Wingrove, Miller, and Klink (2016) examined 110,000 office visits to primary care providers between 2002 and 2010. In the second article, Clarke (2016), an internist and gastroenterologist, presents a model for diagnosing and treating MUS. The person most referenced in the first two articles and author of the landmark study-Kroenke (2016) writes the third article, an invited commentary...
