INTRODUCTION Hypovolemia and hypovolemic shock are life-threatening conditions that occur in numerous clinical scenarios. Near-infrared spectroscopy (NIRS) has been widely explored, successfully and unsuccessfully, in an attempt to use it as an early detector of hypovolemia by measuring tissue oxygen saturation (StO2). In order to investigate the measurement site dependence and probe dependence...

OBJECTIVE The objective of this study was to calculate central motor conduction time (CMCT) of median and ulnar nerves in normal volunteers. Conduction time across the lower part of the brachial plexus was measured by using magnetic stimulation over the motor cortex and brachial plexus and recording the evoked response in hand muscles. DESIGN This descriptive study was done on 112 upper limbs...

Functional magnetic resonance imaging (fMRI) is a technique that uses blood oxygen-level-dependent (BOLD) signals to elucidate discrete areas of neuronal activity. Despite the significant number of fMRI human brain studies, few researchers have applied fMRI technology to investigating neuronal activity within the human spinal cord. Our study goals were to demonstrate that fMRI could reveal the ...

In 1930 Foerster described an operation for restoring opposition of the thumb in cases of paralysis of abductor brevis and opponens pollicis ; a bone graft was inserted between the first two metacarpals to maintain the thumb in palmar abduction and opposition. The method was elaborated by Thompson (1942) and the results in seven cases were reviewed. Both authors were satisfied that the function...

Forty lumberjacks who had used a chain saw for 0-20 years and who had no general disease affecting the bones were studied by measuring the thenar muscle blood flow of both hands by the 133-Xe local clearance method. Bone mineral in the left forearm in the region of cancellous and cortical bone was assessed by the 241-Am gamma ray attenuation method. Virbration was found to decrease the blood fl...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014203963 DESCRIPTION Lipomas are among the most common of all tumours occurring almost anywhere in the body. They usually arise in the subcutaneous layer consisting of lobules of fat with a surrounding capsule which may become tethered to neighbouring structures. 2 Patients ar...

The mechanism of mirror movements in two patients was investigated; one with congenital mirror movement, the other with schizencephaly. Transcranial magnetic stimulation on one side elicited motor evoked potentials (MEPs) in their thenar muscles on both sides with almost the same latencies, minimal thresholds, and cortical topographies. During voluntary contraction of the thenar muscle on one s...

INTRODUCTION Subutex is a sublingual formulation of buprenorphine that is used to treat opioid dependency. It may be abused parenterally with disastrous consequences. CLINICAL PRESENTATION We present 4 cases of parenteral abuse of Subutex resulting in severe upper limb complications. TREATMENT Two vascular complications were treated with combinations of anticoagulants, vasodilators, brachia...

Inhibition of calcium-activated neutral protease, in muscle and nerve, by the tripeptide leupeptin after median nerve transection and epineural repair in monkeys (Cebus apella) was studied. Results indicate that inhibition of the protease after nerve repair facilitates morphologic recovery in denervated thenar muscles and in distal thenar nerve branches. In addition, functional recovery was fac...
