[1] [18] The compression of these spinal nerve roots that control sensation and movement in the lower body results in the tingling, pain and weakness NC patients often experience. However, because the severity of symptoms does not correlate well with the degree of stenosis and nerve root compression, a clear understanding of the specific ...
Subacute combined degeneration of spinal cord; Diagram of the principal fasciculi of the spinal cord. (In subacute combined degeneration of spinal cord, the "combined" refers to the fact that the dorsal columns and lateral corticospinal tracts are both affected, in contrast to tabes dorsalis which is selective for the dorsal columns.)
The radioisotope thallium-201 (as the soluble chloride TlCl) is used in small amounts as an agent in a nuclear medicine scan, during one type of nuclear cardiac stress test. Soluble thallium salts (many of which are nearly tasteless) are highly toxic and they were historically used in rat poisons and insecticides. Because of their nonselective ...
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
Spurling's test is somewhat specific when used for individuals with an abnormal electromyogram study and is a relatively sensitive physical examination maneuver in diagnosing cervical spondylosis or acute cervical radiculopathy. It is not a very sensitive test when used for individuals without classic radicular signs suggestive of cervical ...
The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.
The thallium was slipped into bottles of Coca-Cola at the Carr and Trepal homes. [27] Thallium was the poison of choice for Saddam Hussein to use on dissidents, which even allowed for them to emigrate before dying. [28] In 1995, Zhu Ling was the victim of an unsolved attempted thallium poisoning in Beijing, China.
Thallium-201 is synthesized by the neutron activation of stable thallium in a nuclear reactor, [18] [19] or by the 203 Tl(p, 3n) 201 Pb nuclear reaction in cyclotrons, as 201 Pb naturally decays to 201 Tl afterwards. [20] It is a radiopharmaceutical, as it has good imaging characteristics without excessive patient radiation dose.
