The Algal Growth Potential Test has been an accepted standard test for measuring the bioavailability of nutrients in water bodies. A shortened seven day test has been developed, tested, and shown to have a strong correlation relationship with algal tests grown to maximum dry weight yields. The new test will save time in processing the samples and processing of test data.

Case: A 19-year-old female servicemember with history of ischiopubic rami stress fractures was referred to orthopaedic surgery for magnetic resonance imaging findings concerning for a tension-sided femoral neck stress fracture. However, her history and symptoms were discordant with the diagnosis of stress fracture. The patient was managed with protected weight-bearing for 6 weeks with gradual return to physical activity. Conclusion: Prophylactic surgical fixation is advocated for the management of tension-sided femoral neck stress fractures. However, surgeons should consider a broader differential diagnosis, to include a synovial inclusion cyst, when the clinical presentation is not consistent with a stress fracture.

During the months of March through September 1972, a biological survey was conducted on the effects of a 7,000-gallon diesel fuel spill into Boone Creek, a small stream near Salem, South Carolina. Boone Creek empties into Lake Keowee, an impoundment on the Keowee River. Macroinvertebrate organisms, periphyton, and fish were collected, preserved, identified, and enumerated. Sediment samples were taken for hydrocarbon analysis. Oil was observed in the creek during the entire six-month study period. Locations downstream from the oil spill generally contained reduced numbers and types of organisms. An estimated 90% of the fish community was killed during the initial oil spill. Periphyton growths, dominated by diatoms, increased at locations downstream from the oil spill during May and June. Analysis of substrate sediment samples revealed hydrocarbons still present in Boone Creek and Lake Keowee 13 months after the spill occurred.
