20161738 Moreno-Torres A, Rosset-Llobet J, Pujol J, Fabregas S, Gonzalez-de-Suso JM: Work-related pain in extrinsic finger extensor musculature of instrumentalists is associated with intracellular pH compartmentation during exercise. PLoS One. 2010 Feb 9;5(2):e9091.

BACKGROUND: Although non-specific pain in the upper limb muscles of workers engaged in mild repetitive tasks is a common occupational health problem, much is unknown about the associated structural and biochemical changes.
In this study, we compared the muscle energy metabolism of the extrinsic finger extensor musculature in instrumentalists suffering from work-related pain with that of healthy control instrumentalists using non-invasive phosphorus magnetic resonance spectroscopy ((31) P-MRS).

Less is known about how oxidative capacities in distinct muscles, in the same individual, are affected by different levels of physical activity.
Phosphorus magnetic resonance spectroscopy was used to measure the rate of phosphocreatine recovery (k (PCr)), which reflects the rate of oxidative phosphorylation, following a maximal voluntary isometric contraction of the TA and VL in healthy untrained (7 women, 7 men, 25.7 +/- 3.6 yr; mean +/- SD) and trained (5 women, 7 men, 27.5 +/- 3.4 yr) adults.

We describe a patient with PHPT who presented with progressive proximal limbs weakness and dystrophic changes of leg muscles.
Serum calcium, alkaline phosphatase, and parathyroid hormone were elevated and serum phosphorus was low.

Cervical MRI demonstrated a 11 x 9 cm calcified tumoral mass extending to the cervical muscles and the lower cervical spine (C6, C7, T1), accompanied by C6 osteolysis.
Laboratory studies revealed secondary hyperparathyroidism with elevated calcium-phosphorus product.

At steady-state exercise, specific force of plantar flexion, phosphocreatine consumption measured by phosphorus spectroscopy and maximum perfusion measured by arterial spin-labeled (ASL) NMR imaging were identical in both groups.
Histology showed an increased proportion of type IIb fibers in hypertrophied muscles, but the distribution of capillary contacts per fiber between oxidative and glycolytic fibers was unaltered in mstn (-/-) compared with WT.
