Using prices of hospital admissions and visits to five types of physicians, we analyzed how provider and insurer market concentration-as measured by the Herfindahl-Hirschman Index (HHI)-interact and are correlated with prices. We found evidence that in the range of the Department of Justice's and Federal Trade Commission's definition of a moderately concentrated market (HHI of 1,500-2,500), ins...

Background Patients with lumbar disc disease may present with low back pain, pain that radiates down to the lower extremity (radiculopathy), and leg pain that increases with ambulation (neurogenic claudication). Patients may first undergo diagnostic studies (magnetic resonance imaging, computed tomographic examinations) to determine whether there is any significant nerve root or thecal sac comp...

Giant cell tumor (GCT) is classified as a benign bone tumor, and it is frequently identified at the epiphysis of long bones and relatively rare in the temporal bone. For orthopedists expert at recognizing bone and soft tissue tumors, the diagnosis of GCT is relatively easy; however, since head and neck surgeons experience few cases of GCT, it may be difficult to diagnose when it occurs in the t...

A group of 3 busy orthopedists attended coding education each year and did their best to accurately code and document their services. As a risk-reduction strategy, the group engaged our firm to conduct an audit to determine whether they were documenting their services properly and to provide feedback about how they could improve. What we found was shocking to the surgeons, but all too common, a...

STUDY DESIGN Cross sectional data from the Yamaguchi low back pain study conducted in Yamaguchi prefecture, Japan, was used for this analysis. METHODS A total of 320 patients were recruited from walk-in orthopedic clinics in Yamaguchi Prefecture, Japan. Patients visited the clinics primarily for low back pain (LBP) and sought treatment between April and May 2015. A self-questionnaire was comp...

OBJECTIVE This study evaluated the epidemiological profile of patients with suspected physical abuse, especially regarding the occurrence of fractures, treated in a referral hospital. METHODS The authors reviewed all reports of suspected abuse against children and adolescents (AACA) in this hospital from January 2005 to December 2015. They were assessed and separated by month and year. The ch...

The skeletal dysplasias form a large group of hereditary disorders characterized by abnormal growth and malformations of bone and cartilage. The clinical severity ranges from mildly affected short stature to lethal forms. Spranger classified approximately 200 different skeletal dysplasias in 1992, based on the clinical and radiographic features and the mode of genetic transmission. Etiopathogen...

This paper aims at estimating pathological subjects from a population through various physical information using genetic algorithm (GA). For comparison purposes, K-Means (KM) clustering algorithm has also been used for the estimation. Dataset consisting of some physical factors (age, weight, and height) and tibial rotation values was provided from the literature. Tibial rotation types are four ...

Rotator cuff (RTC) disease is a particularly prevalent cause of shoulder pain and weakness presenting to primary care physicians, internists, rheumatologists, and orthopedists. An understanding of the anatomy of the RTC tendons and the underlying pathogenesis aids in the diagnosis, which is based largely on history and specific physical examination tests. Imaging may further define the patholog...

INTRODUCTION The close anatomical relationship between the skeletal and connective systems of the pelvis, neurological, and vascular structures and pelvic organs are predisposing factors for structural and functional damages of the urogenital system. MATERIALS AND METHODS We performed PUBMED and MEDLINE search using terms "pelvic ring trauma/disruption, bladder injury, urethral injury, sexual...
