(C) Repeated diagnostic blocks are mandatory before any attempted chemical or physical denervation. (D) Are reliable as prognostic aids for neurolytic procedures. (E) Pain relief from a saline block does not indicate a psychogenic pain or malingered pain.

20. Choice a right description about acute pain associated with chemotherapy toxicity. (A) Intraperitoneal chemotherapy seldom induces abdominal pain. (B) Vincristine treatment can induce peripheral neuropathy. (C) ntrathecal methotrexate produces an acute menigitic syndrome in 80% of patients (D) 5-fluorouracil (5-FU) produces peripheral neuropathy but no chest pain. (E) None of above is right.

21. About the failed back surgery syndrome (FBSS), which one of the following procedure may be the last to be considered due to possible poor response? (A) caudal steroids injection (B) epidural adhesive lysis (C) spinal cord stimulation (D) radiofrequency denervation (E) lumbar sympathetic block

22.

24. About chemical neurolytic nerve blocks, which one of following statements is wrong? (A) Phenol or ethanol is usually used for chemical denervation. (B) The duration of these blocks is often disappointingly brief. (C) They may induce deafferentation-neuropathic type pain. (D) They are often indicated for patients with chronic pain and a normal life expectancy. (E) They can be used in patients with advanced cancer disease.

25. Choice a right description about treatment of cancer pain. (A) Because of the complexity of cancer pain, 3 analgesic ladder from WHO was not useful. (B) Surgery, Chemotherapy and radiotherapy are not the analgesic titration for cancer pain. (C) Only 10-20% of patients ultimately require regular strong opioids. (D) Constipation is common for opioid use, but laxative can be used only when symptom exists. (E) None of above is right

26. 有關 hyperalgesia 的描述何者為非？ (A) 組織受傷會導致許多促進發炎反應的化學物質的釋放，包括 bradykinin，prostaglandins， leukotrienes，serotonin，histamine，substance P，thromboxanes，platelet-activating factor， adenosine，ATP， protons 以及 free radicals 等等 (B) Hyperalgesia 不僅發生在受傷的區域，也會發生在周圍未受傷的區域 (C) 在周圍未受傷害的區域產生的 hyperalgesia 稱之為 primary hyperalgesia. (D) 在發炎反應的時候，marcopharges 會釋放 cytokines 來調節發炎反應。 (E) 促進發炎反應之因子，如 cytokine 會促進神經生長因子之產生，再直接或間接地加強疼 痛現象。

27. A 25-year-old, obese man complains of a burning pain in the anterolateral thigh. Deep tendon reflexes and findings in a motor examination are normal. There is a slight sensory deficit in the lateral thigh that corresponds to the painful area. What is the most appropriate diagnostic block to perform on this patient? (A) Epidural local anesthetic and sterioid (B) Trigger point injection (C) Lateral femoral cutaneous nerve block (D) Illioinguinal nerve block (E) Lumbar sympathetic block

28. Which of the following treatment is NOT the indication for limbs pain induced by increased spasticity after C7 incomplete spinal cord injury? (A) Joint positioning and range-of-motion (ROM) exercises. (B) Treat underlying spasticity-triggering events (infection, pressure ulcer, etc). (C) Serial casting or dynamic splinting to relieve already-occurred contractures. (D) Oral narcotics, like codeine or tramadol. (E) Anti-spasticity blocks via Botulinum toxins, phenol, or ethanol.

29. 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.
