However, effects in clinical outcome do not necessarily imply a superiority of the intervention from an economic point of view. Despite an increasing number of cost-utility and cost-effectiveness studies, systematic reviews outline the methodological heterogeneity of studies, which makes it impossible to perform meta-analyses and to draw conclusions from the studies. Recent publications add interesting information to the current discussion; these studies cover the long-term development of sickness absence post-intervention and the cost effectiveness of wor...

Much of the data analyzed comes from the recently published United States Cluster Headache Survey. This is the largest study of cluster headache patients ever published and is the first study to focus on inhaled oxygen and cluster headache in a large, non-clinic-based population.

Conversely, there has been little work focused on the patient–provider relationship in chronic pain settings despite the complexities and difficulties that are often involved in this area. This review provides a brief, broad overview of the literature on the patient–provider relationship and identifies key aspects that are specifically relevant to chronic pain settings. In addition to reviewing the literature in this area, a series of recommendations for future clinical and academic work are offered. Conte...

Tension-type headache and migraine are the commonest phenotypes that can result from head trauma, while the onset of cluster headache (CH) in close temporal relation to a head trauma has only been described in rare cases. Nevertheless, CH patients seem to incur more frequent traumatic head injuries during their lifetimes when compared to migraine controls and the general population. The basis of this association remains unclear, since only a limited number of methodologically robust studies have examined it. However, three main hypotheses can be proposed to explain this association: head trauma is the direct cause of CH; head trauma is a risk factor for the future development of CH; and head tra...

The operant model focuses on pain behaviors as a major component of the pain problem, and postulates that they are subject to environmental contingencies. The role of operant learning in pain behaviors generally has been supported by experimental studies, which are reviewed in the present article. Subsequently, the rationale, goals, and methods of operant behavioral treatment of chronic pain are outlined. Special attention is paid to three therapeutic techniques (graded activity, activity pacing, and time-contingent medication management), which are discussed in detail with regard to their operationalization, effectiveness, and (poss...

Patients with chronic migraine, chronic tension-type headache, hemicrania continua, and new daily-persistent headache have constant pain more often than not. Patients with trigeminal autonomic cephalalgias such as cluster headache commonly have interictal pain as well, usually much milder and unilateral to the side of attacks. Even those with rare headache types, including hypnic headache and trigeminal neuralgia, commonly have interictal pain. This review describes the incidence of interictal pain in primary headache disorders and suggests the significance and biological meanings of this pa...

Provocation discography, an invasive spinal procedure, has been suggested as a diagnostic test for internal disc disruption to provide information on disc morphology and reproduction of symptoms. Current applications consist of the evaluation of persistent spinal pain in individuals, including postoperative patients, as well as providing a guide for patient selection for spinal fusion surgery and minimally invasive interventional pain procedures. While the validity of discography has been questioned by multiple scientific studies, technical refinements have addressed many of the initial limitations. An updated review on the safety and utility of discography will be provided, covering key areas of ...

In this manuscript, the available evidence about the usefulness of diagnostic imaging and image guidance in planning and delivering pain treatment is critically reviewed. The use of image guidance has become a routine and integral component of pain treatment; however, there is insufficient scientific evidence to judge whether this has improved safety. The logical appeal is overwhelming, to the point that it is now unlikely that scientific comparisons of most techniques with and without radiographic guidance will ever be conducted. This analysis can serve to...

Several questionnaires have been used to assess dependent behavior in patients with MOH. Findings regarding underlying psychological profiles of dependence and MOH are not consistent. Nevertheless, several neuroimaging, genetic, and neurobiological studies support the existence of the common pathophysiological features of dependence and MOH and suggest a link between them. This review highlights recent studies on the relationship between dependence and MOH. This issue is important because it implie...

Secondary causes can be suspected through “red flags” in the history and examination. With a prevalence of at least 1% and several associations, primary CDH is a common, often complex, chronic pain syndrome in children and adolescents. The intricate associations between stressors, psychiatric disorders (especially anxiety and depression), and CDH can be explained by “the limbically augmented pain syndrome” proposed by Rome and Rome. Disorders of sleep and other pain syndromes also may co-occur. For these reasons, a multiaxial classification is ideal. Many with primary CDH have features of both chronic migraine and chronic tension-type headache, contributing to confusion in subtyping. Primary CDH is ...

The diagnostic block is considered to be a valuable tool for confirming facetogenic pain. It was demonstrated that a block of the ramus medialis of the ramus dorsalis is preferred over an intra-articular injection. The outcome of the consequent radiofrequency treatment is not different in patients reporting over 80% pain relief after the diagnostic block than in those who have between 50% and 79% pain relief. There is one well-conducted comparative trial assessing the value of one or two controlled diagnostic blocks to none. The results of the seven randomized trials on the use of radiofrequency treatment of facet joint pain demonstrate that good pati...

This article provides an evidence-based review of ESI, including data on efficacy, patient selection, comparison of types, and complications. The data strongly suggest that ESI can provide short-term relief for radicular symptoms but are less compelling for long-term effects or relief of back pain. Although it has been asserted that transforaminal ESIs are more efficacious than interlaminar injections, the evidence supporting this is limited.

Population-based studies have shown that those with CM demonstrate higher individual and societal burden because they are significantly more disabled than those with EM and have greater impaired quality of life both inside and outside the home. Proper diagnosis of both conditions requires clearly defined clinical criteria. Diagnosis enables the initiation of appropriate treatments and risk-factor modification, which ultimately improve functional status and quality of life for persons with migraine. Recognizing that both disorders are on the spectrum of migraine, this review serves as a guide to define the disease state of CM as ...

The most frequent external factor that leads to headache chronification is medication overuse. The neurobiological bases of headache chronification and of the vicious circle of medication overconsumption are not completely elucidated. More recently, the same neurophysiological methods used to study episodic migraine were applied to CM and medication-overuse headache (MOH). Studies of cortical responsivity tend overall to indicate an increase in excitability, in particular of somatosensory and visual cortices, reflected by increased amplitude of evoked responses, decreased activity of inhibitory cortical interneurons reflected in the s...

These changes include upregulation of calcitonin gene–related peptide, substance P, and nitric oxide synthase in trigeminal ganglia; expansion of receptive field and decreased nociceptive threshold of central trigeminal neurons; decrease in diffuse noxious inhibitory control; and increased susceptibility to develop cortical spreading depression (CSD). These changes indicate an increase in excitability of cortical and trigeminal neurons. The neuronal hyperexcitability may be the result of derangement of a central, possibly serotonin (5-HT)-dependent, modulating control system. Experiments wi...

It leads to diabetes and heart disease and shortens lifespan. Although not a risk factor for migraine, it is associated with an increased frequency and intensity of migraine. Obesity is also comorbid with chronic daily headache and is a major risk factor for chronification of episodic migraine in adults and children. Although obesity is not a factor in the effectiveness of migraine treatment, it does increase the peripheral and central events in migraine, ultimately increasing the neurologic potential for migraine. Although evidence suggests that obesity is a modifiable risk factor for migraine progression, it is unknown if weight loss is related to decrease in headache frequency. Recent surgical results sugges...

Primary headache patients do not necessarily develop MOH after acute medication overuse, although a pre-existing primary headache is inevitably present. Likewise, headache patients may deteriorate in terms of frequency without medication overuse, or suffer from chronic headache in the presence of drug abuse without any causal relationship. To classify and define diagnostic criteria for MOH in the absence of objective biomarkers is a difficult task that is presently based on clinical grounds and is limited in part by the relative lack of research in this fi...

Diagnosis of TTH is based merely on clinical features and on careful exclusion of all possible causes of headache. Most of the headaches that present in the context of medical disorders (e.g., hypothyroidism, sleep disorders, and hypertensive crisis) have clinical features overlapping with those of TTH; medical history and specific features of the systemic disorder are usually the clues to establish a correct diagnosis.

Mechanisms responsible for the increased myofascial pain sensitivity have been studied extensively. Peripheral activation or sensitization of myofascial nociceptors could play a role in causing increased pain sensitivity, but firm evidence for a peripheral abnormality still is lacking. Peripheral mechanisms are most likely of major importance in episodic TTH. Sensitization of pain pathways in the central nervous system due to prolonged nociceptive stimuli from pericranial myofascial tissues seem to be responsible for the conversion of episodic to chronic TTH. Treatment directed toward muscular factors inc...

Exercise is commonly recommended in the management of people with fibromyalgia, and interest in examining exercise benefits for those with the syndrome has grown substantially over the past 25 years. Research supports aerobic and strength training to improve physical fitness and function, reduce fibromyalgia symptoms, and improve quality of life. However, other forms of exercise (e.g., tai chi, yoga, Nordic walking, vibration techniques) and lifestyle physical activity also have been investigated to determine their...

Even though sleep recording is not part of the routine evaluation, polysomnography may disclose primary sleep disorders in patients with fibromyalgia, including obstructive sleep apnea and restless leg syndrome. In addition, genetic background and environmental susceptibility link fibromyalgia and further sleep disorders. Among nonpharmacological treatment proposed for sleep disturbance in fibromyalgia, positive results have been obtained with sleep hygiene and cognitive-behavioral therapy.

Medication management often is insufficient to adequately treat the ensuing pain or the complications of medical management limit acceptable dosage for pain control. In these instances, interventional modalities are an additional tool in the pain physician’s armamentarium. Most commonly employed are intrathecal opioids, local anesthetic and clonidine infusions, neurolytic-nerve and sympathetic-ganglion blockade, and radiofrequency techniques. These are discussed in this article concomitantly with current outcome data as reported in the medical literature. Content Type Journal ArticlePages 1-7DOI 10.1007/s11916-011-0206-2Authors ...

Up to one fourth of all women have migraine, and 20% of them experience migraine without aura attack in at least two thirds of their menstrual cycles. The current literature is analyzed in response to the question of whether menstrual and nonmenstrual migraine attacks are different. The different studies provide conflicting results, so it is not possible to answer the question firmly. Future studies should be based on the general population. Collection of both prospective and retrospective data is warranted, and headache diagnosis base on interviews by physicians with interest in headache are more precise than lay interviews or questionnaires.

Current evidence suggests that the temporal profile of the spontaneous electrical activity at an MTP is similar to focal muscle fiber contraction and/or muscle cramp potentials, which contribute significantly to the induction of local tenderness and pain and motor dysfunctions. This review highlights the potential mechanisms underlying the sensory-motor dysfunctions associated with latent MTPs and discusses the contribution of central sensitization associated with latent MTPs and the MTP network to the spatial propagation of pain and motor dysfu...

Pain severity is at least moderate for most patients experiencing cancer-related pain. Pain may also persist in long-term cancer survivors. Cancer-related pain adds to mood disturbance and disability in cancer patients. Despite the frequent occurrence and substantial impact from cancer pain, both patient and provider barriers limit the identification and treatment of pain in cancer patients.

Many psychophysical studies attempted to establish pain perception changes across menstrual cycle in animal models and healthy women or those with chronic pain. General results are quite uncertain in regard to consistent menstrual-related fluctuations of pain perception. The few studies applying neurophysiological procedures to test pain-related changes during menstrual cycle suggested a fluctuation of central modulation of pain across phases, with a prevalence of excitatory versus inhibitory control in the premenstrual period, which may explain the cyclic worsening of many syndromes, such as migraine. Whatever is the relevance of menstrual cycle on individual painful symptoms, it should be acce...

Epidemiological studies indicate that they are comorbid disorders. However, the nature of the comorbidity is not known with certainty, but a likely explanation may be common susceptibility genes. Another possibility is that, because they both are related to pain, increased pain sensitivity induced by one of the disorders may lead to a higher likelihood of developing the other, possibly mediated by nitrogen oxide or prostaglandins. A common link to the widespread use of estroprogestins may seem less probable. For physicians dealing with women with either of these disorders, awareness of ...

Treatment of chronic migraine headache with onabotulinumtoxinA has recently been shown to be effective in reducing the severity and frequency of chronic migraine headache, in the PREEMPT trials, a landmark achievement. However, the studies use a primarily fixed dose and site approach to treatment, allowing some individualized injections. However, the authors do not address the issue of myofascial trigger points as potential triggers of migraine that could be inactivated using onabotulinumtoxinA, despite several studies that support the role of myofascial trigger points in initiating some migraine headaches.

In December 2008, the US Food and Drug Administration issued a warning suggesting that the use of all AEDs is associated with an increased risk of suicidal ideation and behavior. This warning has been received by the medical community with great skepticism, and the validity of the findings of the meta-analysis that led to its publication has been questioned because of various methodological problems. Yet, migraine by itself is associated with an increased risk of suicidal ideation and behavior as well as with an increased risk of psychiatric disorders that facilitate the development of suicidal behavior. Furthermore, TP...

Weak opioids are used for mild-to-moderate pain as monotherapy or in a combination with nonopioids. For patients with moderate-to-severe pain, strong opioids are recommended as initial therapy rather than beginning treatment with weak opioids. Adjunctive therapy plays an important role in the treatment of cancer pain not fully responsive to opioids administered alone (ie, neuropathic, bone, and visceral colicky pain). Supportive drugs should be used wisely to prevent and treat opioids’ adverse effects. Understanding the pharmacokinetics, pharmacodynamics, interactions, and cautions with commonly used opioids can help determin...

Migraine without aura (MO) benefits from the hyperestrogenic state of pregnancy and the lack of hormonal fluctuations, while migraine with aura (MA) presents distinctive features. Indeed, a very strong improvement of MO has been documented across gestation, and only a minority of pregnant women still suffers during the third trimester. On the other hand, fewer women with MA report improvement or remission, and new onset of aura may be observed during pregnancy. After delivery, breastfeeding exerts a protective action on migraine recurrence. The persistence of migraine during gestation seems to affect neonatal outcomes, and several studies indicate a link between migraine a...

The paroxysmal and rather intense head pain usually is unilateral, spreading from the back of the head to the frontal and temporal regions, and triggered by certain movements or sustained provocative head positions. Digital pressure over triggering areas at the upper nuchal area reproduces the spontaneous pain pattern. Available clinical criteria differentiate this picture from other headache disorders, although superposition may be present in some cases. The neck is involved with other pain disorders apart from CeH. Migraine may be induced by cervical trigger factors in some cases, and whiplash lesions produce CeH-like symptoms as well as others. Occipital neuralgia refers to pain restricted to the dist...

Secondary headaches, such as headaches associated with vascular disease, head trauma, and neoplasm, are more common. Also, certain headache types tend to be geriatric disorders, such as primary cough headache, hypnic headache, typical aura without headache, exploding head syndrome, and giant cell arteritis. This review provides an overview of some of the major and unusual geriatric headaches, both primary and secondary. Content Type Journal ArticlePages 1-7DOI 10.1007/s11916-011-0196-0Authors Cynthia C.

By definition, the headache has to occur in a close temporal relationship to the intracranial disorder. Some of these headache disorders are caused by high or low cerebrospinal fluid pressure; noninfectious inflammatory diseases such as neurosarcoidosis, aseptic (noninfectious) meningitis, and lymphocytic hypophysitis; or intracranial neoplasm. Other nonvascular headaches, including hemicrania epileptica and postseizure headache, Chiari malformation type I, and the syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis, are attributed to hypothalamic or pituitary hyper- or h...

This review provides updated information about the classification, assessment, and treatment of BTcP, with special emphasis on the use of opioids. Due to its slow onset to effect, oral opioids cannot be considered an efficacious treatment of BTcP. More recently, different technologies have been developed to provide fast pain relief with potent opioid drugs, such as fentanyl, delivered by noninvasive routes. Transmucosal, buccal, sublingual, and intranasal fentanyl have been shown to provide rapid analgesia in comparison with oral morphine or placebo and are available for clin...

According to the second edition of the International Classification of Headache Disorders, there are 196 possible headache diagnoses, of which 113 have been described in pediatric population. Herein, we focus on unusual pediatric headache syndromes. We group them as headaches with migraine features, short-duration headaches with autonomic features, short-duration headaches without autonomic features, and potentially ominous forms of headaches. Although rare as single entities, providers focusing on pediatric headaches certainly will face some of these headaches and need to be comfortable on the diagnostic approach. Con...

This past year has yielded a wealth of clinical research focused on headache, which should streamline the diagnostic workup of nontraumatic headaches (particularly the search for subarachnoid hemorrhage) and several comparative efficacy trials, which help clinicians determine how best to treat acute migraine with parenteral medications. Herein, we review and contextualize the most important recent developments with regard to management of headache in the acute care setting.

Spontaneous and evoked neuronal excitability normally are well controlled by neural circuits. However, SCI produces maladaptive synaptic circuits in the spinal dorsal horn that result in neuronal hyperexcitability. After SCI, activated primary afferent neurons produce enhanced release of glutamate, neuropeptides, adenosine triphosphate, and proinflammatory cytokines, which are known to be major components for pain transmission in the spinal dorsal horn. Enhanced neurochemical events contribute to neuronal hyperexcitability, and neuroanatomical changes also contribute to maladaptive synaptic circuits and neuronal hyperexcitability. These neuroche...

Given the recent advances that brain-imaging techniques have contributed to our understanding of how chronic pain affects multiple aspects of brain function (including sensory, emotional, cognitive, and modulatory), opportunities to use these approaches in the clinic are clearly a focus of research laboratories around the world. The routine application of brain imaging as a clinical marker of disease state or therapeutic (drug) efficacy would significantly enhance the clinical process by providing objective measures for clinicians and patients.

The most needed changes concern so-called chronic migraine. The revised ICHD-2 (ICHD-2R) did introduce appreciable changes to the ICHD-2 diagnostic criteria for chronic migraine. To be more relevant to actual clinical practice, the classification should discriminate between forms of migraine without aura depending on low, medium, or high frequency of attacks. The classification should include transformed migraine, an appellation that seems preferable to c...

The problem could be attributed to a nonspecific diagnostic criteria, unknown pathophysiologic causes, and limited treatment options. The two forms of CRPS still are painful, debilitating disorders whose sufferers carry heavy emotional burdens. Current research has shown that CRPS I and CRPS II are distinctive processes, and the presence or absence of a partial nerve lesion distinguishes them apart. Ketamine has been the focus of various studies involving the treatment of CRPS; however, currently, there is incomplete data from evidence-based studies. The question as to why ...

Many population studies show that patients with migraine consume alcohol in a smaller percentage than the general population. Moreover, research has shown a decreased prevalence of headache with increasing number of alcohol units consumed. The classification criteria of alcohol-related headaches remain problematic. We discuss the role and mechanism of action of alcohol or other components of alcoholic drinks in relation to alcohol-induced headache. In accordance with data from a recent prospective study, we believe that reports overestimate the role of alcohol, as well as other foods, in the triggering of migraine. If a relationship bet...

Isolated tonsillar herniation is of limited utility and should be considered within the clinical context because these patients can be asymptomatic. Cine MRI showing compression of the cerebrospinal fluid (CSF) spaces in the foramen magnum area is a crucial technique for making treatment decisions. Congenital malformation is thought to be due to a volumetric small posterior fossa. The most common symptom in these patients is cough headache. Posterior fossa reconstruction is mandatory in patients with progressive symptoms/signs, hydrocephalus, or syringomyelia, but not in patients who are asymptomatic or those with stable and tolerable symptoms. Acquired tonsillar descent c...

Not only does it significantly affect quality of life, but it also is a source of frustration for both the patient and physician because the etiology for pain often is unknown. Although patients typically complain of neuropathic-type pain, nerve conduction studies and other conventional diagnostic procedures frequently fail to reveal objective evidence of neurologic disease. However, in recent years, the growing use of specialized tests such as skin biopsy and sudomotor testing has helped to establish the diagnosis of small-fiber neuropathy as the cause of pain in these patients via objective and quantifiable means. Management of sarcoidosis small-fiber neuropathy should consist...

Diagnosis of small-fiber neuropathy is determined primarily by the history and physical exam, but functional neurophysiologic testing and skin biopsy evaluation of intraepidermal nerve-fiber density can provide diagnostic confirmation. Management of small-fiber neuropathy depends on the underlying etiology with concurrent treatment of associated neuropathic pain. A variety of recent guidelines proposes the use of antidepressants, anticonvulsants, opioids, topical therapies, and nonpharmacologic treatments as part of the overall management of neuropathic pain. Unfortunately, little data about the treatment o...

Although there is some agreement that stable, moderate dosing is desirable; longer-term management of patients with chronic pain often confronts clinicians with difficult decisions regarding when to intensify opioid treatment and when to declare failure. Under these circumstances the concern for addiction arises with uncomfortable frequency in specialty settings. An emerging literature has defined a number of plausible markers of risk for aberrant opioid use behaviors in clinical chronic pain populations. Some of these risk factors involve the presence of comorbid psychiatric illnesses, which puts clinicians in the difficult position of deciding whether or not to limit treatment to patient...

With the increased prescription of opioids, some unintended consequences have occurred. After prolonged opioid exposure, opioid-induced hyperalgesia (OIH), the paradoxical effect that opioid therapy may in fact enhance or aggravate preexisting pain, may occur. Over the past several decades, an increasing number of laboratory and clinical reports have suggested lowered pain thresholds and heightened atypical pain unrelated to the original perceived pain sensations as hallmarks of OIH. However, not all evidence supports the clinical importance of OIH, and some question whether the phenomenon exists at all. Here, we present a nonexhaustive, brief review of the recent lit...

It will focus on four key practices that providers can engage in before and during the course of opioid therapy that we believe will enhance the likelihood that opioids, when used, are an effective tool for pain management: avoiding sole reliance on opioids; using adequate opioid doses to address pain; mitigating the risk of opioid misuse by patients; and fostering collaborative relationships for treating complex patients.

For example, in some cases, attempts to control, reduce, or cure pain through medication, medical procedures, or lifestyle changes can prove unsuccessful, and can dominate all other potential goals. The experience of chronic pain also includes other discouraging, painful, or unwanted psychological experiences, such as thoughts, feelings, and memories. Attempts to control or reduce some of these psychological experiences also can prove unsuccessful and even harmful, further reducing quality of life. This review highlights recent evidence for the utility of acceptance as an alternative when control-based...

Headaches increase in frequency over time, becoming less intense but more disabling and less responsive to treatment. Results of electrophysiologic and functional imaging studies indicate that chronic migraine is associated with abnormalities in the brainstem that may be progressive. Additionally, chronic migraine is associated with a greater degree of impairment in cortical processing of sensory stimuli than is episodic migraine, perhaps due to a more pervasive or persistent cortical hyperexcitability. These findings fit with the model of migraine as a spectrum disorder, in which the clinical and pathophysiological features of migraine may progress over time...

In CH, patients undergo single-session focused irradiation of the trigeminal nerve root (TN), sometimes coupled with irradiation of the sphenopalatine ganglion (SPG) as well. SRS provides early pain relief in most patients, but is associated with trigeminal sensory dysfunction in some patients. In the future, a prospective trial that compares a single target of TN to dual targets of both the TN and SPG may provide further understanding of the value of SRS for CH.

Hypothalamic involvement is supported by several neuroimaging, neuroendocrine, genetic, experimental pain, and animal studies. Unfortunately, these different studies were unable to resolve the paramount question of whether the detected hypothalamic alterations are pathognomonic for TACs or whether they merely represent an epiphenomenon of different pain conditions in general. This review summarizes studies on hypothalamic involvement in TAC pathophysiology, demonstrates ...

The critical features of the original description and the subsequent Silberstein-Lipton description was the onset: daily headache starts abruptly without a background of frequent or worsening headache. In 2004, the International Headache Society classification committee excluded an abundance of migrainous features. The exclusion of patients with too many migrainous features from the International Headache Society classification was contentious from the onset and is a source of consternation for many headache experts. Many contend that the sudden onset of a daily headache raises the same issue of what turned on the headache, irrespective of the headache features. Switch-relat...

DBS has a considerable history, and it can be used successfully for a wide number of pain syndromes. Epidural motor cortex stimulation (MCS) also is a treatment option for neuropathic pain. Less invasive than DBS, MCS has been rapidly adopted and studied since first described in 1991. A growing body of literature supports the use of MCS for facial pain, though further study to better define the mechanism of action and the most appropriate patient populations is ongoing.

Similar to other persistent pain conditions, the physical discomfort associated with NTOS can cause severe and often debilitating symptoms. In fact, those suffering from the syndrome report a quality of life impacted as significantly as those with chronic heart failure. This evidence-based literature review focuses on the classification, etiology, clinical presentation, diagnostic measures, and surgical treatment of NTOS, with a focus on nonoperative therapies such as physical modalities, pharmacological therapies, and more contemporary minimally invasive intramuscular treatments with botulinum toxin.

Since the term was first coined in 1984, more than 100 cases have been described worldwide. Most recently, detailed case series that provide more detailed information concerning the sometimes complex clinical presentation of HC have been reported. Functional imaging studies suggest a unique pattern of subcortical involvement in HC: contralateral to the pain posterior hypothalamic region, ipsilateral dorsal pons and ipsilateral ventral midbrain, which, along with the particular effect of indometacin, probably justifies its classification as a unique entity. Increasing the awareness of this primary headache form among clinicians wil...

The most commonly used definition is headache on more than 15 days per month in patients with migraine. Chronic migraine is difficult to treat and requires a multidisciplinary approach. Only two pharmacological treatments have been shown to be effective in placebo-controlled randomized trials: topiramate and local injection of botulinum toxin. Both therapies are effective in patients with chronic migraine with and without medication overuse. Many other substances have been investigated in chronic daily headache. All trials were underpowered and, therefore, recommendations concerning possible efficacy are not possible.

Emerging evidence suggests that episodic migraine and chronic migraine differ not only in degree, but also in kind. Compared with patients with episodic migraine, those with chronic migraine have worse socioeconomic status, reduced health-related quality of life, increased headache-related burden (including impairment in occupational, social, and family functioning), and greater psychiatric and medical comorbidities. Each year, approximately 2.5% of patients with episodic migraine develop new-onset chronic migraine (ie, chronification). Understanding the natural disease course, improving treatment and management, and preventing the onset could reduce the e...

Additionally, the number of patients who utilize complementary and alternative medicine as a treatment of pain either in lieu of, or concurrent with, standard conventional treatments continues to grow. While research into the mechanisms, side effect profiles, and efficacies of these alternative therapies has increased in recent years, much more remains unknown and untested. Herein, we review the literature on complementary and alternative medicine for pain, with particular emphasis on evidence-based assessments pertinent to the most common alternative therapies, including acupuncture, herbal therapy, massage therapy, hypnosis, tai chi, and biofeedback.

MOH manifests as increased frequency and intensity of migraine attacks and enhanced sensitivity to stimuli that elicit migraine episodes. Although the mechanisms underlying MOH remain unknown, it is hypothesized that repeated use of antimigraine drugs could elicit increased headache attacks as a consequence of neuronal plasticity that may increase responsiveness to migraine triggers. Preclinical studies show that exposure to either opiates or triptans can induce pronociceptive neuroadaptive changes in the orofacial division of the trigeminal ganglia that persist even after discontinuation of the drug treatm...

Two common causes are cervical facet arthropathy and occipital neuralgia. Clinical diagnosis is difficult because of the overlying features between primary headaches such as migraine, tension-type headache, and CH. Interventional pain physicians have focused on supporting the clinical diagnosis of CH with confirmatory blocks. The treatment of cervical facet arthropathy as the source of CH is best approached with a multidimensional plan focusing on physical therapy and/or manual therapy. The effective management of occipital neuralgia remains challenging, but both injections and neuromodulation are promising options. Content Type Journal ArticleDOI 10.1007/s11916-010-0151-5Authors J.

Even as treatment options continue to improve, quality of life should remain a priority. Headache drastically impacts the quality of life of patients with cancer and has a wide etiological scope, making diagnosis a challenge. Intracranial mass lesions are only one cause; others include extracranial tumors, paraneoplastic processes, and the consequences of diagnostic and therapeutic interventions used in cancer care. Fortunately, cancer-related headache is treatable, but a sound understanding of the variable etiologies is crucial to appropriate diagnostic evaluation and treatment.

These headache types can be differentiated based on strict clinical definitions that depend on the patient’s signs and symptoms. However, some of the clinical features can overlap, and in addition, the same comorbid conditions can occur in both headache types. Distinction between these headache types on occasion can be difficult due to comorbid conditions such as temporomandibular joint disorders and myofascial pain with forward head posturing, which may be present in both headache disorders, and thus result in similar features in both conditions. Furthermore, chronification, particularly of migraine, leads to a decrease in the associated symptoms of migraine, such as nausea, photophobia, and...

NDPH distinguishes itself from CTTH and the other forms of chronic daily headache by its continuous head pain from onset. However, despite formalized criteria that specify NDPH must resemble the acute onset of a headache identical to that of CTTH, NDPH commonly has migraine features. Here, we review the available literature on NDPH and compare its clinical features, epidemiology, prognosis, inciting factors, and treatment to CTTH.

We argue that the association between migraine and MS is biologically plausible and is confirmed by most studies. We discuss possible explanations for the association. First, we consider the possibility that the association is spurious. Next, we consider unidirectional causal models in which one of the conditions increases the risk of the other. A bidirectional model would suggest that each disease predisposes to the other. Alternatively, genetic or environmental risk factors shared by each condition may account for the association between them. We also address the question of whether coexisting migraine or te...

Radiation therapy potentially may be used for its treatment. Several key issues must be addressed in patients with emergent cancer pain before initiating radiation. These issues include whether the necessary diagnostic information is available, whether the tumor will respond rapidly to radiation, and whether there are additional patient factors that will affect treatment. If these questions have been addressed, it is more likely that a successful outcome will be obtained if radiation therapy is used for the management of emergent cancer pain.

Behavioral studies have not been useful in understanding the relationship between sex hormones and pain perception, and certainly have not helped to elucidate the mechanisms by which such effects may be mediated. This review aims to address the additional insights functional imaging has given us into the role of sex hormones in pain. Functional imaging techniques and experimental designs are discussed before the literature investigating specific questions relating to hormones and pain is reviewed.

There is significant variability in the frequency and severity of migraine throughout the menstrual cycle. Women report migraines occur more frequently during menses, and that those are more severe than other migraines. This creates a unique challenge of effectively treating menstrually related and pure menstrual migraines. As with treatment of other migraines, both abortive and prophylactic treatment regimens are used. Triptans demonstrate efficacy in the abortive management of menstrually related and pure menstrual migraines. For migraines that occur primarily during menses or that are particularly resistant to other therapies, intermittent prophylactic therapies can be used. Naproxe...

The most common causes for central pain are vascular lesions to the brain and the spinal cord, multiple sclerosis, and spinal cord injury. Clinically, central pain typically develops with a delay after the lesion. The pain typically is localized in an area of abnormal sensitivity corresponding to the preceding central lesion. Spontaneous pain and also evoked pains can be found. Pathophysiologically, ectopic neural activity and hyperexcitability are driven by pathological facilitatory and disinhibitory processes. In addition to medical history and clinical examination, diagnosis of central pain is based on imaging and electrophysi...

Targets include the spinothalamic tract, the trigeminal tract nucleus, the midline ascending visceral pain pathway, the brainstem spinal lemniscus, the thalamus, and the cingulate gyrus. Since the introduction of intrathecal opioids, the need for neurosurgical destructive procedures has been in decline. In recent years, cordotomy, trigeminal tractotomy, and dorsal root entry zone (DREZ) operations are the neurosurgical procedures most often utilized to treat cancer pain. The addition of CT guidance to spinal cord pain pathway ablation was a major addition and refinement to the procedure. Here the authors review the latest techniques and recently pu...

Although many women do not require specific treatment of their symptoms, approximately 20% to 50% report moderate to severe premenstrual symptoms and about 5% meet the diagnostic criteria for premenstrual dysphoric disorder, the most severe manifestation of premenstrual symptoms. While the etiology of premenstrual symptoms remains unclear, several theories have implicated sex steroids and neurotransmitters in the development and manifestation of symptoms. Further complicating the delineation of etiology is that premenstrual symptoms can be somatic, psychological, or behavioral, as well as a combination of all three. Developing successf...

Most studies have been case series and many show benefit for patients with migraine, cluster headache, and postconcussive headache. A double-blind, controlled trial of cluster headache has demonstrated that injectable steroids with local anesthetics benefit cluster headache patients. A double-blind, controlled trial of nerve blocks in occipital neuralgia, which may have actually been chronic migraine, was positive.

Myofascial trigger points merit special attention because its diagnosis requires examinations skills and its treatment requires specific techniques. If undiagnosed, the patients tend to be overinvestigated and undertreated, leading to chronic pain syndrome. Patients with myofascial pain syndrome present primarily with painful muscle(s) and restricted range of motion of the relevant joint. Palpable painful taut bands are named trigger points and are the main and pathognomonic finding on physical examination. Eliciting local twitch response and referred pain requires experience and examination skills. It may be useful to classify the patient...

Certainly, the role of female sex hormones in migraine has been well established, yet the mechanism behind this well-known relationship remains unclear. This review focuses on the potential role of hormonally related genes in migraine, summarizes results of candidate gene studies to date, and discusses challenges and issues involved in interpreting hormone-related gene results. In light of the molecular evidence presented, we discuss future approaches for analysis with the view to elucidate the complex genetic architecture that underlies the disorder. Content Type Journa...

In view of the aging demographics, myofascial pain promises to be an even greater challenge to health care in the future. Myofascial trigger points have been identified as important anatomic and physiologic phenomena in the pathophysiology of myofascial pain. While their pathophysiologic mechanisms are still unclear, emerging research suggests that trigger points may be initiated by neurogenic mechanisms secondary to central sensitization, and not necessarily by local injury. A variety of treatments are employed in the management of trigger points, including manual therapy, electrotherapy, exercise, and needle therapy. Therapeutic ultrasound demonstrates significant potential...

The widespread spontaneous pain pattern in fibromyalgia (FM) is a summation of multiple regional pains due to active MTrPs. A regional pain in FM is from local active MTrPs and/or referred from remote active MTrPs. Positive tender points specified in FM are MTrPs, either active or latent. Manual stimulation of active MTrPs located in the muscles in different body regions completely reproduced overall spontaneous FM pain pattern. Active MTrPs as tonic peripheral nociceptive input contribute tremendously to the initiation and maintenance of central sensitization, to the impairment of descending inhib...

Neurolytic blocks are a mainstay in the armamentarium of cancer pain management, more so in intractable pain from advanced cancer. There is no clear consensus on patient selection, technique, or timing of these blocks.

Headache as a result of trauma is one of the most common secondary headache types. Posttraumatic headache (PTH) remains a very controversial disorder, particularly with relation to chronic PTH following mild closed-head injury. PTH is one of several symptoms of PCS, and therefore may be accompanied by additional cognitive, behavioral, and somatic problems. PTH also is an important public health issue due to its associated disability and often refractory clinical course. While current awareness of PTH has become more prominent due to increased scrutiny given to both combat-related and sports-related head injuries, directed treatm...

Prevalence of headache in patients with MS was reported to be higher than 50%, but it is uncertain if this is different than what is seen in the general population. Nonetheless, it is possible that MS and headaches are comorbid. Case reports illustrated that isolated MS lesions (eg, in “strategic” regions like the midbrain) may cause severe headaches often resembling migraine. Furthermore, the role of MS disease-modifying agents needs to be taken into consideration. Mode of action and side effect profiles differ, and treatment per se may sometimes trigger headache in patients with MS. Thorough evaluation of headache in patients with MS is crucial to optimize patient m...

First described in 1988 by Raskin, this headache syndrome was adopted by the International Classification of Headache Disorders in 2004 within the “other primary headache” group (code 4.5). Since then, additional case reports and case series were published and provided data to best understand hypnic headache. This review highlights new findings to discuss the relevance of actual diagnostic criteria and the treatment approach of this nocturnal headache syndrome.

This has led to a rapid increase in opioid prescribing in an effort to address the growing public health problem of chronic pain. A new paradigm in noncancer pain management has emerged, that of risk assessment and stratification in opioid therapy. Techniques foreign to cancer pain management have now become commonplace in the noncancer pain setting, such as the use of monitoring compliance via urine drug screens. Amidst these strides in opioid use for pain management, cancer has been changing. The survival rate has increased, and a group of these patients with chronic pain were treated with opioid therapy. With opioid exposure being longer and against the backdrop o...

Although nearly everyone has occasional headaches, there are well-defined headache disorders that vary in incidence and prevalence. Among the unusual headache syndromes, headache due to external compression is a poorly studied headache considered to arise as a result of continued stimulation of cutaneous nerves by the application of pressure over the scalp or forehead. The wearing of bands around the head, specifically goggles (such as those worn for swimming), tight hats, or even professional helmets have been described as causative factors. The pain is often constant and more severe at the location where the object is pressing the head. In predisposed patients (ie, those with migrain...

While the vast majority of headaches are due to benign primary headache disorders, a small but important minority of headaches are due to secondary causes. Whereas significant emphasis is placed on educating physicians regarding prompt recognition of subarachnoid hemorrhage and headaches secondary to brain tumors, attention toward headaches secondary to infectious causes is often neglected. Unfortunately, a missed or delayed diagnosis of a headache secondary to meningitis, encephalitis, brain abscess, subdural empyema, or other infectious etiologies can lead to dire consequences for both the patient and physician. Accordingly, this article provides an overview of headaches attributed to systemic and intra...

Migraine and epilepsy are both chronic disorders with episodic attacks. Furthermore, headache may be a premonitory or postdromic symptom of seizures, and migraine headaches may cause seizures per se (migralepsy). Migraine and epilepsy are comorbid, sharing pathophysiological mechanisms and common clinical features. Several recent studies identified common genetic and molecular substrates for migraine and epilepsy, including phenotypic-genotypic correlations with mutations in the CACNA1A, ATP1A2, and SCN1A genes, as well as in syndromes due to mutations in the SLC1A3, POLG, and C10orF2 genes. Herein, we review the relationship between migraine and epilepsy, focusing on clinical aspects and some recent...

Fasting headache is coded to Group 10 of the second edition of the International Classification of Headache Disorders (“Headache attributed to disorder of homeostasis”). A study conducted in Denmark’s general population found a lifetime prevalence rate of 4.1% for fasting headache. Fasting headache is usually diffuse or located in the frontal region, and the pain is nonpulsating and of mild or moderate intensity.

The likelihood of developing fasting headache increases directly with the duration of the fast. Headache sufferers have a higher risk of developing headache dur...

Although they confer benefit to the patient, high doses and extended duration of use may lead to significant adverse effects. Adverse effects such as osteoporosis-induced fractures, osteonecrosis, myopathy and myalgias can cause significant pain and have a negative impact on the patient’s quality of life. In this paper, I will review the mechanisms involved in the toxicity, risk factors, prevalence, prevention, and treatment strategies.

Migraineurs report odours may trigger attacks, that they experience osmophobia during attacks, and olfactory hypersensitivity between attacks. In this paper we discuss olfactory mechanisms in migraine. We also present data from a pilot questionnaire study in a group of young women diagnosed with migraine. The study results confirm that hypersensitivity to odour is a common feature in women with migraine. Migraine pathophysiology likely explains this particular vulnerability. We discuss these pathophysiologic mechanisms and hypotheses relating odour intolerances and migraine.

Because of the complex pathologic mechanisms involved in chronic pain, optimal treatment is still under development. The spinal cord is an important gateway for peripheral pain signals transmitted to the brain. In chronic pain states, painful stimuli trigger afferent fibers in the dorsal horn to release neuropeptides and neurotransmitters. These events induce multiple inflammatory and neuropathic processes in the spinal cord dorsal horn, and trigger modification and plasticity of local neural circuits. As a result, ongoing noxious signals to the brain are amplified and prolonged, a phenomenon known as central sensitization. In this review, the molecular events associated with centr...

It is classified as type I (reflex sympathetic dystrophy) and type II (causalgia). CRPS cannot be reduced to one system or to one mechanism only. In the past decades, there has been absolutely no doubt that complex regional pain syndromes have to be classified as neuropathic pain disorders. This situation changed when a proposal to redefine neuropathic pain states was recently published, which resulted in an exclusion of CRPS from neuropathic pain disorders. We analyzed the strength of the scientific evidence that supports the neuropathic nature...

Proposed diagnostic criteria differentiate CEH from migraine and tension-type headache (TTH) in most of the cases. The best differentiating factors include side-locked unilateral pain irradiating from the back and evidence of neck involvement—attacks may be precipitated by digital pressure over trigger spots in the cervical/nuchal areas or sustained awkward neck positions. Migrainous traits may be present in some cases. Cervical lesions are not necessarily seen, and most common cervical lesions do not produce CEH. Whiplash may occasionally induce headaches. This is suspected when the pain onset and the whiplash trauma are close in time. Whiplash-related headaches tend to be short-lasting, admitting mostly...

An EMR for migraine should allow customization to include fields important in migraine, such as migraine frequency and severity, weight, blood pressure, and outcome measures, such as the Migraine Disability Assessment. The physical examination should focus on common abnormalities, such as muscle spasm, allodynia, or papilledema, and allow free text to describe uncommon findings. Information from previous notes should be available for inclusion in the current visit, such as diagnoses and the plan from the previous visit. In the future, EMR will work with clinicians to reco...

An argument is developed against the standard advice to avoid migraine triggers as the best way of preventing attacks, based on conceptual and practical criticisms, and consideration of cognate literatures on chronic pain, stress, and anxiety. A small number of studies suggest that exposure to headache triggers has the same effect as exposure to anxiety-eliciting stimuli, with short exposure associated with increased pain response and prolonged exposure associated with decreased pa...

By definition, angiographic abnormalities disappear within 3 months. The clinical course is usually benign, with a higher prevalence in young women. RCVS is idiopathic in the majority of the cases. However, recent papers have outlined the role of precipitating factors, including the use of vasoactive substances. Some patients, nevertheless, have a more severe clinical course with transient or permanent ischemic events. Hemorrhagic complicat...

Although many anatomical, molecular, and functional components have been identified, a comprehensive and integrated theory of pain perception has yet to be firmly established that fits the diverse clinical experience. Acute pain involves the activation of several varieties of small primary sensory neurons, collectively termed nociceptors, which have small-caliber unmyelinated or myelinated axons (C and Aδ fibers, respectively) that innervate all body tissues. They are stimulated by noxious stimuli that activate ion channels on the endings either directly or through the release of cytokines from damaged or stressed tissues. A variety of drugs successfully treats acute pain by targeting these ion channel...

Sufficient evidence links dysesthetic pain, trigeminal neuralgia, Lhermitte’s sign, and painful tonics spasms to plaque formation in the spinal cord and brain, whereas the association with headache and back pain remains unclear. Management varies according to the pain in question. For dysesthetic pain, drugs in use for neuropathic pain in general are recommended as first-line treatment, and emerging evidence suggests some benefit from cannabinoids and levetiracetam. Because of unique characteristics of MS-related trigeminal neuralgia, ganglion and root level neuroablative procedures are worth considering before microvascular decompression. Overal...

The calculated prevalence of CH in reproductive-aged women is 7.5 of 100,000 women. Although data suggest that CH during pregnancy is a relatively rare condition, when it does occur, attacks remain unchanged in character and severity in the majority of patients. Thus, treatment of CH in pregnant and lactating women may remain a significant therapeutic challenge. This manuscript briefly reviews the epidemiology of CH in women, and then focuses on treatment options for both acute and preventative management of CH in pregnant and lactating women.

Recent evidence from clinical trials shows that medically supervised modified fasting (200–500 kcal nutritional intake/day) with periods from 7 to 21 days is efficacious in the treatment of rheumatic diseases and chronic pain syndromes. Here, fasting is frequently accompanied by increased alertness and mood enhancement. The beneficial claims of fasting are supported by experimental research, which has found fasting to be associated with increased brain availability of serotonin, endogenous opioids, and endocannabinoids. Fasting-induced neuroendocrine activation and mild cellular stress response...

Recent studies indicate that 50% of all countries, including 79% of the G-20 countries, continue to practice systematic torture despite a universal ban. It is well known that torture has numerous physical, psychological, and pain-related sequelae that can inflict a devastating and enduring burden on its victims. Health care professionals, particularly those who specialize in the treatment of chronic pain, have an obligation to better understand the physical and psychological effects of torture. This review highlights the epidemiology, classification, pain sequelae, and clinical treatment guidelines of torture victims. In addition, the role of pharmacologic and psychologic interventions is explored in the context of...

Lidocaine is also an important anesthetic and topical agent that is useful in the treatment of multiple pain disorders, and mexiletine is commonly used for neuropathic pain and myotonia. Both intravenous lidocaine and mexiletine are increasingly used to treat pain syndromes and appear to be particularly effective in neuropathic pain. This suggests a role for these agents in patients with headache disorders. This article describes the role of intravenous lidocaine and mexiletine in the management of headache and trigeminal autonomic cephalalgias based on the published literature to date and provides practical guidelines for their use.

It is a strictly unilateral head pain that is associated with cranial autonomic symptoms and usually follows circadian and circannual patterns. Chronic cluster headache, which accounts for about 10% to 15% of patients with cluster headache, lacks the circadian pattern and is often resistant to pharmacological management. The sphenopalatine ganglion (SPG), located in the pterygopalatine fossa, is involved in the pathophysiology of cluster headache and has been a target for blocks and other surgical approaches. Percutaneous radiofrequency ablation of the SPG was shown to have encouraging results in those patients with intractable cluster headaches.

A genetic basis has been suggested by family and twin studies, but the mode of transmission seems to vary and the amount of heritability is unclear. The number of genetic association studies investigating variants implicated in the pathophysiology of CH is limited. The HCRTR2 1246G > A and the ADH4 925A > G polymorphisms have been associated with CH. The former has been confirmed and may affect the hypothalamic hypocretin system. However, it only appears to account for a part of the genetic susceptibility for CH, and additional genetic and environmental factors are likely implicated. Pharmacogenetic studies have suggested that the GNB3 825C > T polymorphism may modify treat...
