Fracture of an elastic humeral nail. A case report.

The use of elastic intramedullary nails for the treatment of diaphyseal fractures of the humerus has been associated with few complications. We report a fracture of an elastic Marchetti-Vicenzi nail used to treat a pathological fracture of the humerus. The failure of the intramedullary nail followed low-energy trauma and was presumably the end result of metal fatigue, as the original fracture had only healed after 13 months.

Effects of lifetime volleyball exercise on bone mineral densities in lumbar spine, calcaneus and tibia for pre-, peri- and postmenopausal women.

To clarify the effects of habitual volleyball exercise on bone in women during the menopausal periods, we measured bone mineral densities (BMDs) of the lumbar spine, calcaneus and tibia every 12 months for 2 years and estimated factors related to the baseline values and annual loss rates. Forty Japanese female volleyball players 42-62 years of age, who had belonged to the district non-professional club for more than 10 years on average, were recruited. Twenty women had regular menstruation at the start, but 7 underwent menopause during the study. Fifty-nine healthy women who did not participate in habitual exercise, but were otherwise comparable with the players, were recruited as the controls. The lumbar and calcaneus BMDs were measured by dual-energy X-ray absorptiometry (DXA), and both the volumetric BMDs and cross-sectional geometry at the diaphysis of the tibia were measured by peripheral quantitative computed tomography. The baseline BMDs of all measured sites and the values of the cortical area and moment of inertia of the tibia in the players were significantly higher than the values in the control women. In the peri- and postmenopausal players, the baseline values of the lumbar and calcaneus BMDs related to total years of participating in regular exercises during adulthood including volleyball (TYE), body mass index (BMI) and years since menopause (YSM). Tibia cortical area and moment of inertia values related to TYE. Annual bone loss rates in the tibia and calcaneus of players were significantly smaller than those values in the controls. However, the bone loss rates in the lumbar spine did not differ significantly between the groups. The bone loss rate in the calcaneus was significantly related to the current number of training hours per week and YSM. The rate of bone loss in the tibia was related to BMI. These data indicated that the total number of years participating in exercise activity during adulthood have positive effects on lumbar and calcaneus BMDs and the cortical structure of the tibia. Habitual volleyball exercise apparently did not alleviate the menopause-related bone loss in the lumbar spine.

Increased uptake of 99Tcm-ethyl cysteinate dimer in patients with brain tumours.

We performed 229 99Tcm-ethyl cysteinate dimer (ECD) single photon emission tomography (SPET) studies in 185 patients with brain tumour. Increased uptake of the tracer was observed in 11 cases. In six of these 11 patients, focal intense activity was seen in the area surrounding the tumour. Five of these six patients had episodes of seizure, and ictal SPET showed further increased uptake in the area of hyperperfusion in one patient. Hyperperfusion surrounding the tumour might be related to seizure. In the remaining five patients, increased accumulation was seen in the tumour. Three of these five patients had a discrepancy between 99Tcm-ECD SPET and 201Tl SPET imaging. There could be some difference in the mechanism of accumulation in the tumour between 99Tcm-ECD and 201Tl.
