Risk determination for patients with direct access to physical therapy in military health care facilities.

Study Design: Nonexperimental, retrospective, descriptive design.

Objectives: This study was designed to ascertain whether direct access to physical therapy placed military health care beneficiaries at risk for adverse events related to their management.

Background: Military health care beneficiaries have the option at most US military hospitals and clinics to first enter the health care system through physical therapy by direct access, without referral from another privileged health care provider.

Identification and management of 2 femoral shaft stress injuries.

Study Design: Resident's case problem.

Background: Although femoral shaft stress fractures in the general population are rare, they are more common among endurance athletes and military recruits. Such individuals presenting with a complaint of hip, thigh, or knee pain should raise suspicion for femoral shaft stress injury.

Evaluation of specific ultraviolet absorbance as an indicator of the chemical composition and reactivity of dissolved organic carbon.

Specific UV absorbance (SUVA) is defined as the UV absorbance of a water sample at a given wavelength normalized for dissolved organic carbon (DOC) concentration. Our data indicate that SUVA, determined at 254 nm, is strongly correlated with percent aromaticity as determined by 13C NMR for 13 organic matter isolates obtained from a variety of aquatic environments. SUVA, therefore, is shown to be a useful parameter for estimating the dissolved aromatic carbon content in aquatic systems.
