High-pressure injection injuries to the hand.

Analysis of 14 cases of high-pressure injection injury to the hand revealed that the mechanism of injury, the nature of the injected substance, the site of injection, delay in treatment, and treatment specifics all influence prognosis. Injuries from paint or spray guns appear to be the most devastating; injuries to digits are worse than those to the hand. Paint, thinners, and solvents cause great impairment. Delay in treatment likely compromises the outcome; steroids may be effective in some cases in reducing eventual impairment. Early recognition of the gravity of these wounds is important and early decompression, tetanus prophylaxis, antibiotics, and judicious steroid usage are advocated. Significant impairment results from many high-pressure injuries despite seemingly adequate treatment.

Pyogenic granuloma of the hand.

Pyogenic granuloma is a benign, vascular lesion occasionally seen on the hand. It many be quite alarming to the patient. Adequate surgical excision is advocated as the treatment of choice.

Investigation of potential health effects associated with well water chemical contamination in Londonderry Township, Pennsylvania, U.S.A.

A community health survey was conducted by the Pennsylvania Department of Health in Londonderry Township, Dauphin County, Pennsylvania, in response to concerns about potential health effects associated with residential exposure to chemical contaminants in well water. The data indicate that there were no observable adverse health effects in the exposed group of residents, compared with the control group, which could be ascribed to long-term, low-level exposure to trichloroethylene (TCE) and other volatile organic chemicals. Significantly more individuals in the exposed group than in the control group experienced eye irritation, diarrhea, and sleepiness during the 12-month period prior to the survey. This indicated the possibility of an association of contaminated water with the manifestation of symptoms. It is hypothesized that the increased rate of symptoms observed in the exposed group, when compared to the control group, may have been caused by one or more of the following factors: (1) effect of TCE at a threshold level higher than 28 ppb, (2) effect of a single chemical entity other than TCE, and (3) additive or synergistic effects of several chemicals. It is also possible that there are factors other than water contaminants associated with the recorded symptoms, e.g., stress, that may have had an important influence in the exposed group but not in the control group.

Fatty replacement of spinal bone marrow due to radiation: demonstration by dual energy quantitative CT and MR imaging.

Dual energy CT and quantitative magnetic resonance (MR) imaging were used to evaluate marrow changes due to radiation. The bright signal intensity seen on MR was shown by the two quantitative techniques to be due to a threefold increase in the marrow fat content compared with nonradiated levels and to a normal control. Fat estimates by MR and dual energy CT were in excellent agreement. Single energy CT overestimates the amount of bone loss in the radiation field. Dual energy CT and quantitative MR can be used to correct this error.

Hemispherical spondylosclerosis: MR appearance.

We present a case of hemispherical spondylosclerosis (HSS) in a middle-aged woman with low back pain. The plain radiographic findings, CT and MR appearance, and pathological examination are described, and the difficulties encountered in differentiating HSS from malignancy and infection are discussed.
