(E) all of the above are common found in patients with cancre pain

17. Pain is a frequent consequence of spinal cord injury (SCI). Which of the following statement is least likely: (A) Below-level neuropathic pain is most likely described as severe or excruciating months or years following initial injury. (B) Damage to the spinothalamic tracts is an important ingredient in the development of neuropathic pain following SCI.(C) Chronic musculoskeletal pain is common in tetraplegic patients after SCI. (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.

18. The innervation of deep somatic tissue like muscle and joint is quite complex. Which of the following description is not appropriate? (A) The nociceptors are predominantly activated by non-physiological stimuli which may cause damage to the structures (e.g. overload, twisting, strong pressure, ischemic contraction). information within the central nervous system. (B) During inflammation or after trauma, nociceptors of joint and muscle show pronounced sensitization, in particular for mechanical stimuli. (C) Descending inhibition is enhanced during chronic inflammation but seems to be normalized during acute inflammation. (D) Both primary afferent fibers as well as sympathetic reflexes may aggravate inflammatory lesions. (E) Reduced release of hormones from the hypothalamic-pituitary-adrenal (HPA) axis such as cortisol, adrenal androgens and testosterone may cause a relative loss of anti-inflammatory activity..

19. 關於鴉片類藥物的敘述，下列何者最不正確？ (A) Hydromorphone 效力比 morphine 強 3-5 倍(口服)，且具有 NMDA 受體拮抗劑與血 清素再吸收抑制(serotonin reuptake inhibitor)的特性 (B) Buprenorphine 具有 μ receptor partial agonist 及 κ antagonist 之性質 (C) Meperidine(pethidine)具有高度親脂性，容易引發「尋藥行為」(drug-seeking behavior) (D) Tapentadol 具有 μ agonist 與 noradrenaline reuptake inhibitor 之性質 (E) 以皮下作為給藥路徑可以提供緩慢穩定的吸收，唯給藥量不宜超過 5 mL/hr

20. Which of the following is not a common manifestation of the myofascial pain syndrome? (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 .

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.

23. Which of the following oral opioids is not recommended for padiatric patients with cancer pain?(A) morphine (B) hydromorphone (C) oxycodone (D) meperidine (pethidine) (E) all of the above can be prescribed for pediatric patients with cancre pain

24. Adjuvant analgesics are often prescribed for managing caner pain, but which of the following drug – indication is not considered ? (A) NSAIDs for Soft tissue pain (B) Anticonvulsants for Neuropathic pain (C) Steroids for Soft tissue pain (D) Baclofen for Muscle spasm (E) Benzodiazepines for Muscle spasm

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.

27. Which of the following statement concerning painful polyneuropathies with prevalent loss of small fibres is most likely: (A) Chronic renal failure neuropathy. I. (B) Diabetes mellitus neuropathy. (C) Alcoholic neuropathy. (D) Myeloma neuropathy.. (E) soniazid neuropathy.
