Brain plasticity is demonstrated in complex regional pain syndrome (CRPS), although it is unclear how it modulates at different stages of CRPS. The observation that symptoms can progress over time suggests that the pattern of brain changes might also evolve. We measured structural and functional changes as well as sensorimotor integration at early and late stages (ES and LS) of CRPS. Twelve ES patients, sixteen LS patients, and sixteen age- and sex-matched controls were recruited. Gray matter (GM) volume was estimated using voxel-based morphometry...

Objective: This prospective, open-label study was designed to evaluate the long-term effectiveness of 10-kHz high-frequency spinal cord stimulation (SCS) in the treatment of chronic axial low back pain with no history of spinal surgery. Methods: Patients with chronic low back pain without previous spinal surgery underwent assessment by a multidisciplinary pain and surgical team to confirm eligibility. After a successful temporary trial of 10-kHz HF-SCS therapy, defined by ≥50% back pain reduction, enrolled subjects underwent permanent system implantation and were followed up for 36 months...

Background Low frequency (LF) stimulation of the sphenopalatine ganglion (SPG) may increase parasympathetic outflow and provoke cluster headache (CH) attacks in CH patients implanted with an SPG neurostimulator. Methods In a double-blind randomized sham-controlled crossover study, 20 CH patients received LF or sham stimulation for 30 min on two separate days. We recorded headache characteristics, cephalic autonomic symptoms (CAS), plasma levels of parasympathetic markers such as pituitary adenylate cyclase-activating polypeptide-38 (PACAP38) and vasoactive intestinal peptide (VIP), and mechanical detection and pain thresholds as a marker of sensory modulation...

REVIEW
Patricia Tsui, Andrew Deptula, Derek Y Yuan
PURPOSE OF REVIEW: This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. RECENT FINDINGS: Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions...

Shweta Teckchandani, Meredith Barad
PURPOSE OF REVIEW: This review is intended to help the headache physician think through and plan for management issues concerning the use of opioids. We ask the headache physician to consider if there are instances where prescribing or continuing prescriptions of opiates is plausible, and if so, how can the physician proceed as safely as possible. Our goal is to start a conversation regarding the inevitable encounter with a patient on opiates or requesting opiates. RECENT FINDINGS: The use of opiates in our society has reached a crisis in staggering death and addiction rates...

BACKGROUND: We aimed to explore patients' preferences for headache treatments with a self-administered questionnaire including the Q-No questionnaire for nocebo. METHODS: Questionnaires from 514 outpatients naïve to neurostimulation and monoclonal antibodies were collected. RESULTS: Patients assessed that the efficacy of a treatment is more important than safety or route of administration. They preferred to use an external neurostimulation device for both acute (67...

Neuropathic pain is a common phenomenon that affects millions of people worldwide. Maxillofacial structures consist of various tissues that receive frequent stimulation during food digestion. The unique functions (masticatory process and facial expression) of the maxillofacial structure require the exquisite organization of both the peripheral and central nervous systems. Neuralgia is painful paroxysmal disorder of the head-neck region characterized by some commonly shared features such as the unilateral pain, transience and recurrence of attacks, and superficial and shock-like pain at a trigger point...

BACKGROUND: Migraine patients usually report a high prevalence of neck pain preceding or during the migraine attack. A recent investigation of musculoskeletal dysfunctions in migraine patients concluded that neck pain is not simply a symptom of the migraine attack but corresponds to identifiable muscle and joint alterations. Particularly pain provocation using palpation of the joints in the upper cervical spine was significantly more prevalent in patients with migraine than in headache-free participants...

PURPOSE OF REVIEW: The purpose of this article is to focus on an excruciating disorder of the face, named atypical facial pain or persistent idiopathic facial pain (PIFP). It is considered an underdiagnosed condition with limited treatment options. Facial pain can be a debilitating disorder that affects patients' quality of life. Up to 26% of the general population has suffered from facial pain at some point in their lives. It is important to highlight the different types of facial pain to be able to properly manage this condition accordingly...

REVIEW
Simon Vulfsons, Negev Bar, Elon Eisenberg
PURPOSE OF REVIEW: The clinical diagnostic dilemma of low back pain that is associated with lower limb pain is very common. In relation to back pain that radiates to the leg, the International Association for the Study of Pain (IASP) states: "Pain in the lower limb should be described specifically as either referred pain or radicular pain. In cases of doubt no implication should be made and the pain should be described as pain in the lower limb." RECENT FINDINGS: Bogduks' editorial in the journal PAIN (2009) helps us to differentiate and define the terms somatic referred pain, radicular pain, and radiculopathy...

REVIEW
Hida Nierenburg, Morgane Swift Morris
PURPOSE OF REVIEW: External nasal neuralgia is a rare syndrome of atypical facial pain for which there is limited reports in the scientific literature. We aim to review diagnosis and provide an update on treatments for this rare condition. RECENT FINDINGS: Etiology has been documented as post-traumatic due to direct trauma to the nose area and in few case reports, idiopathic. Sensory innervation of the nose arises from the ophthalmic and maxillary divisions of the trigeminal nerve...

Aims To critically appraise, compare and synthesise the quality and acceptability of multi-item patient reported outcome measures for adults with chronic or episodic headache. Methods Systematic literature searches of major databases (1980-2016) to identify published evidence of PROM measurement and practical properties. Data on study quality (COSMIN), measurement and practical properties per measure were extracted and assessed against accepted standards to inform an evidence synthesis. Results From 10,903 reviewed abstracts, 103 articles were assessed in full; 46 provided evidence for 23 PROMs: Eleven specific to the health-related impact of migraine (n = 5) or headache (n = 6); six assessed migraine-specific treatment response/satisfaction; six were generic measures...

Occipital neuralgia is defined as a paroxysmal shooting or stabbing pain in the dermatomes of the nervus occipitalis major and/or nervus occipitalis minor. The pain originates in the suboccipital region and radiates over the vertex. A suggestive history and clinical examination with short-term pain relief after infiltration with local anesthetic confirm the diagnosis. No data are available about the prevalence or incidence of this condition. Most often, trauma or irritation of the nervi occipitales causes the neuralgia...

Epicrania fugax (EF) was recently classified as a primary headache in the Appendix of the International Classification of Headache Disorders, third edition (ICHD-III). It is characterized by a paroxysmal pain rapidly radiating forward or backward along a linear or zigzag trajectory on the surface of the head. This article reports a 76-year-old woman who newly developed a paroxysmal EF-type pain distributed not only in the territories of the trigeminal and occipital nerves, but also in the territories of the cervical and thoracic nerves...

REVIEW
Abhijit S Nair, Basanth Kumar Rayani
The sphenopalatine ganglion (SPG) is a parasympathetic ganglion, located in the pterygopalatine fossa. The SPG block has been used for a long time for treating headaches of varying etiologies. For anesthesiologists, treating postdural puncture headaches (PDPH) has always been challenging. The epidural block patch (EBP) was the only option until researchers explored the role of the SPG block as a relatively simple and effective way to treat PDPH. Also, since the existing evidence proving the efficacy of the SPG block in PDPH is scarce, the block cannot be offered to all patients...

Cluster headache is characterized by severe, unilateral headache attacks of orbital, supraorbital or temporal pain lasting 15-180 min accompanied by ipsilateral lacrimation, rhinorrhea and other cranial autonomic manifestations. Cluster headache attacks need fast-acting abortive agents because the pain peaks very quickly; sumatriptan injection is the gold standard acute treatment. First-line preventative drugs include verapamil and carbolithium. Other drugs demonstrated effective in open trials include topiramate, valproic acid, gabapentin and others...

Cutaneous allodynia is an established marker for central sensitization in migraine. There is debate whether cutaneous allodynia may also occur in cluster headache, another episodic headache disorder. Here, we examined the presence and severity of allodynia in a large well-defined nationwide population of people with cluster headache. Using validated questionnaires we assessed, cross-sectionally, ictal allodynia and comorbid depression and migraine in the nationwide "Leiden University Cluster headache neuro-Analysis" (LUCA) study...
