6. Which of the following is the acceptable statement about pathogenesis of FMS?

(A) There is evidence to suggest that FMS is a disorder of abnormal processing of sensory

information within the central nervous system.

(B) Several neurochemical mediators of pain, substance P, nerve growth factor, dynorphin A,

glutamate, nitric oxide, serotonin and noradrenaline are viewed as pronociceptive because they

carry or amplify afferent signals, leading to the brain perception of increased pain.

(C) The elevation of cerebrospinal fluid substance P in FMS is due to lowered activity of

cerebrospinal fluid substance P esterase because the rate of cleavage of libeled substance P by

FMS cerebrospinal fluid was lower than normal.

(D) In different subtypes of FMS, it is believed that nerve growth factor may be responsible for the

elevated cerebrospinal fluid substance P through its effects on central sensitization and

neuroplasticity.

(E) A specific Gi-protein–coupled receptor in peripheral blood leukocytes was found to be

dysfunctional in patients with FMS. This resulted in lower baseline, also depressed intracellular

levels of cyclic AMP and proposed as a diagnostic test for FMS.

(C) For the majority of patients with neuropathic pain, the realistic goal of treatment, in a

multidisciplinary pain clinic, is total analgesia and improvement in functional status.

(D) Any operation for treating pain should aim to be specific, localized into the pain area, carry

minimal risk and long-lasting.

(E) Neurosurgeons generally try the most peripheral procedures before working centrally within

the CNS, while giving preference to non-neuroablative operation, if possible.

(C) Increases in hypnotic relaxation are associated with increases in regional cerebral blood flow in the occipital cortex.

(D) Deep relaxation, dissociated imagery and focused analgesia produced significant reductions on all pain-related measures.

(E) Descending projections from amygdale, PAG and locus coeruleus contribute to modulate nociceptive processes in the brain stem and the spinal cord.

15. About the intrathecal drug delivery system, which of the following statements is NOT correct?

(A) It places medication directly into the cerebrospinal fluid that surrounds the spinal cord.

(B) Morphine delivered directly to the intrathecal space is particularly effective because it does not
