Following nerve injury in humans, there is evidence that components of the pain state may develop a dependency upon sympathetic activity, as evidenced by the reversal of the pain state after sympathetic blockade. This suggests some interaction between sympathetic nervous system and the injured sensory nerve. Which of the following statements best describes our current understanding of the site or mechanism of that interaction?

A. Follow and peripheral nerve injury, there is sprouting of postganglionic sympathetic if efferent into the dorsal root ganglia and into the Neuroma.

B. While injury may cause sympathetic terminal to sprout, there is no physiological evidence that such sprouting affects the spontaneous activity of injured afferents.

C. Injury leads to an increase in sympathetic terminal activity, and this increase in circulating catecholamines accounts for the increased sensory terminal activity

D. Sympathetic blockade actually serves to block transmission in the sympathetic afferent the travels with the sympathetic efferents. It is a blockade of a transmission in these afferent that is in fact accounts for the observed pain relief produced, for example by regional sympathectomies.

E. Peripheral injury lead to an increased sympathetic innervation of spinal dorsal horn, neurons leading to a facilitation of their response to otherwise innocuous stimulation.

A/E ✔?

The key question is how and where does the sympathetic nervous system become coupled to the sensory nervous system to produce the pain observed in the clinical situation? The basic observation must be that activity in the sympathetic nervous system initiates abnormal impulse traffic in sensory neurones that leads to pain perception.

Tactile allodynia is a common component of post nerve injury pain state (causalgia). Based on our current appreciation of the effects produced by nerve injury, which of the following statements describe the mechanism that are believed to account for this allodynia?
Lost of intrinsic modulation by enkephalinergic projections
Sprouting of A-beta afferents from Lamina III into Lamina II✔

Loss of dorsal horn GABA/ Glycine modulatory neurons✔
a. 1,2,3 only
b. 1,3 only
c. 2,4 only
d. 4 only
e. All are correct

D ?
C✔

Understanding of the peripheral and central mechanisms of the mechanical allodynia has been perceived as follows:

1) increased excitability of peripheral and central terminals and their cell bodies, including local paracrine mechanisms; 2) The reduction in inhibition (disinhibition) in the spinal cord (i.e. the decreased inhibitory activity of GABA/glycinergic interneurons;
3) The reorganization of synaptic connections in the spinal dorsal horn (Aβ-afferents sprout into the superficial layer

The allodynia and hyperalgesia associated with neuropathic pain may be best explained by:

1) the development of spontaneous activity of afferent input 2) the sprouting of large primary efferents (eg. A-beta fibers from lamina 3 into lamina 1 and 2),
3) sprouting of sympathetic efferents into neuromas and dorsal root and ganglion cells,
4) elimination of intrinsic modulatory systems and
5) up regulation of receptors in the dorsal horn which mediate excitatory processes

25. Chronic daily headaches is most often associated with: a. Analgesic rebound b. Chronic cluster headache c. Hemicrania continua d. Orgasmic headache e. Transformed migraine

E? E✔ Transformed migraines are chronic (long-lasting), daily headaches that originate from episodic migraine headaches. Most patients who experience transformed migraines have a history of intermittent migraines, usually beginning in childhood or early adolescence. The onset of daily transformed migraine headaches generally occurs in people during their 20s and 30s.

26. All of the following are indomethacin responsive headaches EXCEPT: a. Hemicrania continua ✔ b. Paroxysmal hemicrania ✔ c. Ice pick headache ✔ d. Sexual headache e. Transformed migraine

D ? E ✔ Indomethacin-responsive headache syndromes represent a unique group of primary headache disorders characterized by a prompt and often complete response to indomethacin to the exclusion of other nonsteroidal anti-inflammatory drugs and medications usually effective in treating other primary headache disorders. Because these headache disorders can easily be overlooked in clinical practice, they likely are more common than previously recognized. Indomethacin-responsive headache syndromes can be divided into several distinct categories: a select group of trigeminal-autonomic cephalgias, valsalva-induced headaches, and primary stabbing headache (ice-pick headache or jabs and jolts syndrome). Each category can be differentiated clinically and by the extent to which the individual headache disorders respond to indomethacin. The paroxysmal and continuous hemicranias invariably respond in an absolute manner to indomethacin, whereas valsalva-induced and ice-pick headaches may respond in an equally dramatic, but somewhat less consistent fashion. Hypnic headache recently has been described as another primary headache disorder that may respond to indomethacin.

Patients with cerebellar ataxia will, generally, be unable to balance even with the eyes open;[6] therefore, the test cannot proceed beyond the first step and no patient with cerebellar ataxia can correctly be described as Romberg's positive. Rather, Romberg's test is a test of the proprioception receptors and pathways function. A positive Romberg's test has been shown to be 90% sensitive for lumbar spinal stenosis. The Romberg test is a test of the body's sense of positioning (proprioception), which requires healthy functioning of the dorsal columns of the spinal cord

B ? E ✔ Neuropraxia least severe Axonotmesis – more sevre Neurotmesis –most severe Classification Grade 1: Neuropraxia Conduction disruption with intact axon and preserved supportive structures Prognosis: Normally full recovery in days to weeks without surgical intervention Grade 2: Axonotmesis Disrupted axon with intact endoneurium; Wallerian degeneration takes place after 1-2 weeks Prognosis: Variable recovery, worse prognosis for proximal injuries and injuries that do not successfully re-implant in the muscle within 18 months Grade 3: Neurotmesis with preservation of perineurium Endoneurium is disrupted Prognosis: 60-80% recovery Grade 4: Neurotmesis with preservation of epineurium Prognosis: Nerve grafting is required Grade 5: Neurotmesis with complete transection of nerve trunk Prognosis: Bypass/jump grafting is required Explanation There are two classification schema used to describe nerve injuries. The first was published by Seddon in 1943, and separated injuries into three categories — neuropraxia, axonotmesis, and neurotmesis — largely based on the scale of injury from microscopic to macroscopic. In 1978, Sunderland expanded upon this idea, subdividing neurotmesis into three additional grades. The Seddon classification is useful to understand the anatomic basis for injury, while the Sunderland classification adds information useful for prognosis and treatment strategies.
