Postherpetic neuralgia is the most frequent complication of herpes zoster. Treatment of this neuropathic pain syndrome is difficult and often disappointing. Although postherpetic neuralgia is generally a self-limited condition, it can last indefinitely. Continuous epidural blockade for patients with acute zoster can shorten the duration of treatment. However, continuous epidural block has some complications such as infection, dural puncture, and total spinal and nerve damages. We report a case of myoclonus during continuous epidural block with ropivacaine, morphine, and ketamine in an acute zoster patient.

Erythromelalgia is a rare neurovascular pain syndrome characterized by a triad of redness, increased temperature, and burning pain primarily in the extremities. Erythromelalgia can present as a primary or secondary form, and secondary erythromelalgia associated with a myeloproliferative disease such as essential thrombocythemia often responds dramatically to aspirin therapy, as in the present case. Herein, we describe a typical case of a 48-year-old woman with secondary erythromelalgia linked to essential thrombocythemia in the unilateral hand. As this case demonstrates, detecting and visualizing the hyperthermal area through infrared thermography of an erythromelalgic patient can assist in diagnosing the patient, assessing the therapeutic results, and understanding the disease course of erythromelalgia.

Botulinum toxin (BTX) is used in various ways such as temporarily resolving muscular problems in musculoskeletal temporomandibular disorders, inducing a decrease in bruxism through a change in muscular patterns in a patient's bruxism, and solving problems in patients with tension headache. And also, BTX is widely used in cosmetic applications for the treatment of facial wrinkles after local injection, but conditions such as temporomandibular joint disorders, headache, and neuropathic facial pain could be treated with this drug. In this report, we will discuss the clinical use of BTX for facial wrinkle, intraoral ulcer, and cranio-maxillofacial pain with previous studies and share our case.

5-Hydroxytryptamine receptor 7 ($5-HT_7R$) is one of G-Protein coupled receptors, which is found to be involved in the pathophysiology of various neurological disorders including depression, sleep disorders, memory deficiency and neuropathic pain. After activation of $5-HT_7R$ by serotonin, it activates the production of the intracellular signaling molecule cyclic AMP. The availability of 3D structure of the receptor would enhance the development of new drugs. Hence, in the present study, homology modelling of human 5-hydroxytryptamine receptor 7 ($5-HT_7R$) was performed using comparative modelling (Easy Modeller) and threading (I-TASSER) approaches. The generated models were validated using Ramachandran plot and ERRAT plot and the best models were selected based on the validation results. The 3D model developed here could be useful for identifying crucial residues and further docking study.

In neurons, nitric oxide(NO) is produced by neuronal nitric oxide synthase following stimulation of N-methyl-D-aspartate(NMDA) receptors and the subsequent influx of Ca$\^$2+/. NO, induced in this manner, reportedly plays critical roles in neuronal plasticity, including neurite outgrowth, synaptic transmission, and long-term potentiation(LTP) (1-7). However, excessive activation of NMDA receptors has also been shown to be associated with various neurological disorders, including focal ischemia, epilepsy, trauma, neuropathic pain and chronic neurodegenerative maladies, such as Parkinson's disease, Hungtington's disease and amyotrophic lateral sclerosis(8). The paradox that nitric oxide(NO) has both neuroprotective and neurodestructive effects may be explained, at least in part, by the finding that NO effects on neurons are dependent on the redox state. This claim may be supported by the recent finding that tissue concentrations of cysteine approach 700 ${\mu}$M in settings of cerebral ischemia (9), levels of thiol that is expected to influence both the redox state of the system and the NO group itself(10).

Of 16 million diabetic patients in the USA, 2.4 millions have experienced diabetic foot ulcer and 67,000 have amputations every year. For treatment of diabetic foot ulcer, Americans spend more than $1 billion each year, including $36,000 per patient for complete treatment and $60,000 for each amputation. Neuropathy and ischemia, two common complications of diabetes mellitus, are the primary underlying risk factors for development of diabetic foot ulcers. Ischemic ulcers develop as a result of low perfusion pressure in the foot with inadequate blood supply, whereas neuropathic ulcers develop from loss of protective sensation. In addition, diabetes also increases the risk of infection by impairing the body's ability to eliminate bacteria. From these circumstances, results are chronic wounds with impaired healing ability.

Intravenous immunoglobulin (IVIg) is the treatment of choice for many autoimmune neuropathic disorders such as Guillain-Barre syndrome (GBS), chronic inflammatory Demyelinating neuropathy (CIDP), and multifocal motor neuropathy (MMN). IVIg is preferred because the adverse reactions are milder and fewer than the other immune-modulating methods such as steroid, other immunosuppressant such as azathioprine, and plasmapheresis. IVIg also has been used in other autoimmune neuromuscular disorders (inflammatory myopathy, myasthenia gravis, and Lambert-Eaton myasthenic syndrome) and has been known as safe and efficient agent in these disorders. Since IVIg would get more indications and be used more commonly, clinicians need to know the detailed mechanism of action, side effects, and practical points of IVIg.

Transcranial magnetic stimulation (TMS) is a noninvasive and safe technique for motor cortex stimulation. TMS is used to treat neurological and psychiatric disorders, including mood and movement disorders. TMS can also treat several types of chronic neuropathic pain. The pain relief mechanism of cortical stimulation is caused by modifications in neuronal excitability. Depression is a common co-morbidity with chronic pain. Pain and depression should be treated concurrently to achieve a positive outcome. Insomnia also frequently occurs with chronic lower back pain. Several studies have proposed hypotheses for TMS pain management. Herein, we report two cases with positive results for the treatment of depression and insomnia with chronic low back pain by TMS.
