Spinal cord and brain tissue impairments as long-term effects of rugby practice? An exploratory study based on T and ihMTsat measures.

Rugby players are subject to multiple impacts to their head and neck that could have adverse neurological effects and put them at increased risk of neurodegeneration. Previous studies demonstrated altered default mode network and diffusion metrics on brain, as well as more foraminal stenosis, disc protrusion and neck pain among players of contact sports as compared to healthy controls. However, the long-term effects of practice and repetitive impacts on brain and cervical spinal cord (cSC) of the rugby players have never been systematically investigated.

[Parathyroid autotransplantation in hemodialysed chronic renal failure. Attempts to modulate secretion. First results apropos of 45 cases].

The authors report their experience of parathyroid autotransplantation in 45 cases of renal insufficiency undergoing hemodialysis. The operation, carried out by two teams, reduces to the minimum the time during which the grafts are exposed to environmental factors likely to impair their function. An immediate anatomopathological examination is necessary to determine the degree of hyperplasia in each gland and the corresponding choice of grafts.

Parathyroid carcinoma, adenoma and hyperplasia in a case of chronic renal insufficiency on dialysis.

A 62 year-old female patient with polycystic disease and chronic renal insufficiency who had required dialysis for 3 years, presented with diffuse but predominantly lumbar bone pain associated with lassitude. Radiologic studies showed diffuse osteoporosis and destruction of the 4th lumbar vertebra. Calcium levels were normal (2.
