Results VO2peak was significantly lower in patients with MCTD compared to the VO2peak of healthy subjects (z-score -1.9, p = 0.008). The strength of the proximal muscles (hip flexors, shoulder abductors, knee extensors) of the patients was significantly lower than the controls, whereas the strength of the distal muscles (dorsal flexors of the foot and grip strength) was rather similar. No clini...

Variants on muscles and tendons of the forearm or hand occur frequently in human beings. They are often discovered during educational cadaveric dissections and surgical procedures. Knowledge of such anomalies is necessary to the surgeons in order to avoid possible damage to adjacent muscles' tendons' blood vessels or nerves. Here we describe a rare muscular variant, the extensor indicis brevis ...

Malignant tumors involving the shoulder girdle can arise from four distinct locations: the proximal humerus, scapula, periscapular muscles, and axillary structures. This article describes a utilitarian shoulder approach that can be used to resect these tumors.

Myasthenia gravis (MG) characteristically involves ocular; bulbar, and proximal limb muscles. MG with predominant distal limb involvement is uncommon. We present a case of MG with distal, asymmetrical, upper limb involvement, seven years after disease onset.

Patient: A 79-year-old man presented with progressive weakness especially in the muscles of his lower limbs for about ten days before admission. He was diabetic, hypertensive and had coronary arterial disease with congestive heart failure for many years. He also had chronic renal insufficiency with a serum creatinine of 1.9 mg/dL. He had been treated with colchicine for gouty arthritis for the ...

The purpose of the present study was to determine the extent to which lower extremity muscular strength is an independent predictor of proximal femur BMD in healthy older adults. It was hypothesized that the BMD of the proximal femur in older adults would not be related to the maximum voluntary isometric strength of the hip, knee, and ankle muscles after adjusting for the influence of body weig...

The distinction between myasthenia gravis and Lambert Eaton myasthenic syndrome can usually be made by the clinical and neurophysiological features. A patient was observed with features which suggested a combination of both disorders. This has been described in few patients before. The importance of electromyography in both distal and proximal limb muscles for a correct diagnosis is demonstrate...

In order to test the regenerative capacity of atrophic axons, a constricting ligature was placed around the proximal tibial nerve of the rabbit, and the nerve crushed at the ankle one week later. Axonal atrophy with altered g ratios was subsequently confirmed in fibres distal to the site of ligature and proximal to the site of crush. In nerves with tight proximal ligatures the reinnervation of ...

Necrotizing autoimmune myopathy (NAM) is a rare subgroup of idiopathic inflammatory myopathies (IIM). This pathology usually affects proximal limb muscles and in some cases the myocardium. Patients usually display proximal limb weakness. Muscular biopsy is required to confirm the diagnosis. We report the case of a 64-year-old woman with an atypical first presentation of NAM, manifested by chest...

A patient is described with proximal diabetic neuropathy presenting with respiratory weakness. A 50 year old man developed progressive shortness of breath over 2 months. He also had weakness of hip flexion. Phrenic nerve responses were absent, and spontaneous activity was seen in the intercostal and lumbar paraspinal muscles with long duration neurogenic MUPs and reduced recruitment in the diap...
