Frozen Shoulder: Diagnosis and Management.

Frozen shoulder is a common condition that causes pain and restriction of movement of the shoulder unrelated to secondary causes. It has three classic phases (freezing, frozen, and thawing), and is resolved in most cases within 1 to 2 years. Diagnosis is clinical based on global motion restriction and pain.

Selected Musculoskeletal Issues in Adolescents.

Musculoskeletal care of the adolescent patient involves unique knowledge of their rapidly changing physical and psychological health. In this article, the importance of preventing early sports specialization is elucidated, and an encouragement of the safety and necessity of resistance training in adolescents is undertaken. It also explores two common conditions, one affecting the immature skeleton (apophysitis), and one affecting the improperly developed muscular system (patellofemoral syndrome), both of which are diagnosed clinically, and require little advanced imaging.

Dietary supplements: physician knowledge and adverse event reporting.

Purpose: Dietary supplement (DS) use among US military personnel is widespread. Many consume several different DS with multiple ingredients one or more times each week, representing a potential public health concern. The overall purpose of the study was to assess the knowledge and behaviors of health professionals and physicians regarding patterns of DS use and possible adverse events (AE) associated with DS use.

Relative bioavailability and bioaccessibility and speciation of arsenic in contaminated soils.

Background: Assessment of soil arsenic (As) bioavailability may profoundly affect the extent of remediation required at contaminated sites by improving human exposure estimates. Because small adjustments in soil As bioavailability estimates can significantly alter risk assessments and remediation goals, convenient, rapid, reliable, and inexpensive tools are needed to determine soil As bioavailability.

Objectives: We evaluated inexpensive methods for assessing As bioavailability in soil as a means to improve human exposure estimates and potentially reduce remediation costs.
