(A) Regional body pain and stiffness (B) Abnormal findings on neurological examinationl (C) Limited range of motion of the affected muscle (D) One or more trigger points (E) Referral (triggering) pain from a trigger point to a zone of reference .

21. Which of the following combination of lesion site with referral site describing pain referral is not common in cancer patients suffering from cancer pain? (A) (Diaphragmatic irritation) and (Shoulder) (B) (Urothelial tract) and (Inguinal region and genitalia) (C) (C7–T1 vertebrae) and (Interscapular) (D) (L1–2) and (Sacroiliac joint and hip) (E) all of the above are common found in patients with cancre pain

22. Which of the following suggestion is not advisable for the use of opioids in children with cancre pain? (A) Use the oral route first in most circumstances (B) Treat constipation pre-emptively. (C) If side effects are bothersome with one opioid, consider switching to another one. (D) Use sufficient doses to keep the patient comfortable should be avoided due to the possible occurrence of adverse effects (E) Use the oral route first in most circumstances.

25. Which of the following cell type sense the initial “endanger signal” and participates in the initial phase of pathogenesis of the nerve injury induced neuropathic pain? (A) Microglia (B) Spinal lamina I and II neuron (C) Astrocyte (D) oligodendrocyte

26. Which of the following description about spinal cord plasticity and pain is incorrect? (A) Some spinal nociceptive neurons receive convergent input from high- and low- threshold sensory fibers thus called wide–dynamic range neurons (B) Glutamate is the major fast excitatory neurotransmitter in all nociceptive afferent nerve fibers. Glutamate can bind to three types of ionotropic glutamate receptors and to G protein–coupled metabotropic glutamate receptors to modify neuroexcitability. (C) Hyperalgesia and allodynia can even be induced in humans in the absence of any sensory stimuli, such as during prolonged application of opioids or on abrupt withdrawal of opioids..(D) Spinal nociception is under powerful control from descending inhibitory and facilitatory pathways. Under normal conditions, descending facilitation appears to prevail over inhibitory pathway.

(D) Patients with cervical SCI are at risk of developing CRPS affecting upper limbs. (E) Below-level neuropathic pain is also referred to deafferentation pain.
