Purpose of Review
This review highlights the importance of osteopathic manipulative treatment (OMT) in headache sufferers. OMT is a viable option for patients who either do not wish to use pharmaceuticals or who have contraindications to pharmaceuticals. Patients with headaches that are refractory to other treatment options may also be candidates for OMT. Multiple headache etiologies are amenable to this non-invasive treatment option and they will be reviewed here. Although there are advantages to using this treatment method, there are also shortcomings in the literature, which will be discussed.Recent Findings
Roughly 45 million Americans suffer from headaches every year. Many headache sufferers are unable to find relief through conventional treatment options. OMT is a useful non-invasive treatment option with little to no side effects. There are multiple headache types. Migraine, tension-type headache, combat-related events, post-traumatic headache, sinusitis, tooth extraction, concussions, and others have all shown benefit from OMT.Summary
OMT is a non-invasive treatment option for individuals suffering from various types of headaches. This treatment option is tailored to the individual needs of the patient and is delivered by licensed and experienced osteopathic physicians. This review of literature also highlights where there is need for further research in the field.2.
Background
Subcutaneous peripheral nerve field stimulation (sPNFS) is an established procedure for the treatment of chronic localized neuropathic pain of peripheral origin. The treatment of nummular headache primarily focuses on conservative methods with limited prospects of success. The role of sPNFS in the treatment of nummular headache has not been investigated as yet.Question
Is the sPNFS an option in the management of nummular headache?Materials and methods
In addition to a summary of established methods in the treatment of nummular headache, sPNFS as a possible form of therapy is discussed.Results
A positive effect of sPNFS in terms of the treatment of nummular headache is shown.Discussion
sPNFS stimulates free subcutaneous nerves and transmits a pleasant form of paraesthesia in the area of pain. If regular conservative therapy has already been exhausted, then sPNFS might be an effective new option in the treatment of nummular headache. sPNFS is a minimally invasive and low-risk procedure. However, the high treatment cost and restrictions regarding fitness to undergo MRI are points of criticism. Further studies are needed to define its potential and role in the treatment of nummular headache.3.
Purpose of Review
In recent years, the awareness of the detrimental impact of concussion and mild traumatic brain injuries (mTBI) is becoming more apparent. Concussive head trauma results in a constellation of cognitive and somatic symptoms of which post-traumatic headache is the most common. Our understanding of post-traumatic headache is limited by the paucity of well validated, characterized, and clinically relevant animal models with strong predictive validity. In this review, we aim to summarize and discuss current animal models of concussion/mTBI and related data that start to shed light on the pathophysiology of post-traumatic headache.Recent Findings
Each of the models will be discussed in terms of their face, construct, and predictive validity as well as overall translational relevance to concussion, mTBI, and post-traumatic headache. Significant contributions to the pathophysiology of PTH garnered from these models are discussed as well as potential contributors to the development of chronic post-traumatic headache.Summary
Although post-traumatic headache is one of the most common symptoms following mild head trauma, there remains a disconnect between the study of mild traumatic brain injury and headache in the pre-clinical literature. A greater understanding of the relationship between these phenomena is currently needed to provide more insight into the increasing frequency of this debilitating condition in both military and civilian populations.4.
Purpose of Review
In this short review, the most common non-invasive neuromodulatory techniques will be described, along with their advantages and disadvantages and their application in headache. Available preventive treatments can be unhelpful or may have unpleasant side effects; moreover, the rate of response to preventive drugs does not exceed 50%, lower in chronic migraine; alternative options would be welcome. Though the concept of neuromodulation was originally developed with invasive methods, newer non-invasive techniques are appearing.Recent Findings
The novel neuromodulatory techniques have been developed with encouraging results: compared with traditional pharmacotherapy, advantages of non-invasive neuromodulation include reduced incidence of adverse effects, improved adherence, and safety and ease of use. The results are encouraging for acute or preventive treatment of different kinds of headache.Summary
A variety of neuromodulatory approaches is expanding fastly and has opened new possibilities for treatment of patients suffering from many forms of headache, especially those who have failed traditional pharmacotherapy. The non-invasive treatments can be seen as supplementing traditional management in refractory patients. Current study results are encouraging but preliminary and larger and more rigorous trials are needed to clarify benefit and mode of action.5.
Purpose of Review
The purpose of this review is to provide an update on the clinical features, diagnosis, pathogenesis, epidemiology, and treatment of the rare primary headache disorders short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with autonomic symptoms (SUNA). Together these entities are known as short-lasting unilateral neuralgiform headache attacks (SUNHA).Recent Findings
Recent case reports of secondary SUNCT and SUNA due to medullary infarcts support the theory that the trigeminohypothalamic pathway is involved in the pathophysiology of SUNHA. While medical therapy for SUNHA has not significantly changed, surgical therapy for refractory SUNCT and SUNA has made advancements with a recent case series demonstrating the efficacy of deep brain stimulation.Summary
We will discuss the pathophysiology of both the pain and the autonomic symptoms experienced in SUNCT and SUNA attacks as well the medical, procedural, and surgical options for treatment with emphasis on recent advances. Specific secondary causes reported in the recent literature will be discussed in brief.6.
Purpose of Review
Chronic headache sufferers are estimated to be around 3% of the population. These patients have a high disease burden. When prophylactic treatments have low efficacy and tolerability, patients are in need of alternative therapeutic strategies and options.Recent Findings
In the last decade, a number of neuromodulation procedures have been introduced as treatment of chronic intractable headache patients when pharmacological treatments fail or are not well tolerated. Neurostimulation of peripheral and central nervous system has been carried out, and now, various non-invasive and invasive stimulation devices are available. Non-invasive neurostimulation options include vagus nerve stimulation, supraorbital stimulation and single-pulse transcranial magnetic stimulation; invasive procedures include occipital nerve stimulation, sphenopalatine ganglion stimulation and hypothalamic deep brain stimulation. In many cases, results supporting their use derive from open-label series and small controlled trial studies. Lack of adequate placebo hampers adequate randomized controlled trials.Summary
In this paper, we give an overview on the main neurostimulation procedures in terms of results and putative mechanism of cation.7.

Background
Intracranial abscesses are rare and life-threatening conditions that typically originate from direct extension from nearby structures, hematogenous dissemination or following penetrating cerebral trauma or neurosurgery.Findings
A 36-year-old male presented to our emergency department with complaints of left eye swelling, headache and drowsiness. On physical exam, the patient was febrile and his left upper eyelid was markedly swollen with fluctuance and drainage. Maxillofacial computed tomography was obtained to evaluate for orbital pathology but revealed bifrontal brain abscesses.Conclusions
Brain abscesses should be considered in the differential diagnosis for patients who present with the classic triad of headache, fever and neurological deficit.8.

Purpose of Review
This article provides an overview of headache in the setting of pituitary adenoma. The purpose of this article is to educate providers on the association, possible pathophysiology, and the clinical presentation of headache in pituitary tumor.Recent Findings
Recent prospective evaluations indicate that risk factors for development of headache in the setting of pituitary adenoma include highly proliferative tumors, cavernous sinus invasion, and personal or family history of headache. Migraine-like headaches are the predominant presentation. Unilateral headaches are often ipsilateral to the side of cavernous sinus invasion.Summary
In summary, this paper describes how the size and type of pituitary tumors play an important role in causation of headaches. Pituitary adenoma-associated headache can also mimic primary headache disorders making recognition of a secondary process difficult. Therefore, this paper highlights the association of between trigeminal autonomic cephalgias and pituitary adenomas and urges practitioners to maintain a high index of suspicion when evaluating patients with these uncommon headache presentations. However, on balance, given the prevalence of both primary headache disorders and pituitary adenomas, determining causality can be challenging. A thoughtful and multidisciplinary approach is often the best management strategy, and treatment may require the expertise of multiple specialties including neurology, neurosurgery, and endocrinology.10.

Purpose of Review
This review evaluates and explains our current understanding of a rare subtype of migraine, typical aura without headache, also known as migraine aura without headache or acephalgic migraine.Recent Findings
Typical aura without headache is a known entity within the spectrum of migraine. Its pathophysiology is suggested to be similar to classic migraines, with cortical spreading depression leading to aura formation but without an associated headache. No clinical trials have been performed to evaluate treatment options, but case reports suggest that most patients will respond to the traditional treatments for migraine with aura. Bilateral greater occipital nerve blocks may be helpful in aborting migraine with prolonged aura. Transcranial magnetic stimulation has shown efficacy in aborting attacks of migraine with aura but has not been specifically tested in isolated aura.Summary
Typical aura without headache occurs exclusively in 4% patients with migraine, and may take place at some point in 38% of patients with migraine with aura. Typical aura without headache commonly presents with visual aura without headache, brainstem aura without headache, and can also develop later in life, known as late-onset migraine accompaniment.12.
Purpose of Review
Pituitary tumors account for approximately 17% of all intracranial neoplasms, with the majority being pituitary adenomas. Often, these are found incidentally during a workup for headache; however, the relationship between symptom and pathology remains unclear. The purpose of this article is to review the most recent literature on the epidemiology, pathophysiology, and management of headaches in patients with pituitary tumors.Recent Findings
The current literature is limited, with few prospective trials focusing on this question. With the exception of pituitary apoplexy, the relationship between headaches and pituitary masses remains unclear. Intervention does not always improve headache and can lead to development of new headache syndromes.Summary
Further research is needed to better elucidate the relationship between pituitary tumors and headaches. Headache alone is rarely an indication for surgical management of a pituitary adenoma.13.

Purpose of Review
In contrast to well-established relationships between headache and affective disorders, the role of alcohol use in primary headache disorders is less clear. This paper provides a narrative overview of research on alcohol use disorders (AUDs) in primary headache and presents a meta-analysis of the role of alcohol as a trigger (precipitant) of headache.Recent Findings
The majority of studies on AUDs in headache have failed to find evidence that migraine or tension-type headache (TTH) is associated with increased risk for AUDs or problematic alcohol use. The meta-analysis indicated that 22% (95% CI: 17–29%) of individuals with primary headache endorsed alcohol as a trigger. No differences were found between individuals with migraine (with or without aura) or TTH. Odds of endorsing red wine as a trigger were over 3 times greater than odds of endorsing beer.Summary
An absence of increased risk for AUDs among those with primary headache may be attributable to alcohol’s role in precipitating headache attacks for some susceptible individuals. Roughly one fifth of headache sufferers believe alcohol precipitates at least some of their attacks. Considerable study heterogeneity limits fine-grained comparisons across studies and suggests needs for more standardized methods for studying alcohol-headache relationships and rigorous experimental designs.14.

Purpose of Review
This review synthesizes the utility of measuring migraine triggers for the purpose of forecasting future headache attacks. The nature of forecasting models, headache triggers as inputs to such models, and how these trigger exposures can be measured for forecasting are reviewed. A critical evaluation of the existing forecasting models in the context of their potential application for preemptive treatment is considered.Recent Findings
A substantial pool of candidate trigger factors could be considered in the creation of forecasting models. However, because mechanistic information about causal factors that precede a migraine attack is not well understood, and such factors are difficult to measure, empirical models that are based on trigger factors that are merely associated with the onset of headache activity are likely to be the focus of forecasting efforts in the near future. Of such factors, stress has considerable empirical support and has been used to successfully forecast future headache attacks within individuals over time. However, at present, existing models possess only modest levels of discrimination and lack strong resolution in generated predictions.Summary
Current headache forecasting models represent an important first step in accurately predicting future headache activity. However, to utilize these models in a preemptive treatment paradigm where the risk of headache is treated prior to the actual experience of pain, these models must achieve greater precision with good calibration and generate predictions that are clinically actionable by individuals in their real-time home environments.15.
Introduction
Chronic tension headache is a common medical problem. Many patients present to manual medicine specialists. Scientific data regarding the relevance of somatic dysfunction for the pathogenesis of chronic tension headache are inconsistent. In order to address this issue, a study protocol was developed. In the present study, the first two steps of the protocol were undertaken.Material and methods
In order to identify valuable functional findings and tests, the first step of the study was a Delphi process. The second step consisted of testing the inter-rater reliability of the suggested tests.Results
In total, 38 different clinical tests were identified to be relevant for chronic tension headache. Inter-rater reliability was reasonable for somatic dysfunction of the cervical spine, as was the test for muscular tension of the trapezius muscle. None of the other tests were found to be sufficiently reliable.Conclusion
We could show that a subset of tests assumed to be relevant for chronic tension headache are reliable. The other tests have to be refined or the study protocol has to adapted to obtain an even distribution of positive/negative findings.16.

Purpose of Review
Chiari malformations (CM) are a group of neuroanatomical pathologies resulting from overcrowding of the hindbrain. The purpose of this review is to characterize Chiari headache (CH) and describe diagnosis and treatment of the condition.Recent Findings
Recent research has helped solidify the criteria for diagnosis of CH. Imaging studies have expanded our understanding of the morphological features producing them and helped to better characterize the pathophysiology. Additionally, identifying this unusual headache disorder accurately has helped with specific treatment options.Summary
CH is a disabling condition which can effect multiple domains of a patient’s life. The diagnostic criteria has improved, and we now have a better understanding of the pathophysiology and imaging findings associated with CH. Future research is warranted to find new treatment options for individuals suffering from this condition.17.

Purpose
High-resolution ultrasound is increasingly used in the diagnosis of carpal tunnel syndrome; yet little is known about gender differences in clinical presentation and ultrasound findings.Materials and methods
In this high-resolution ultrasound-based retrospective study in 170 cases, we assessed gender influence in CTS in terms of the severity of neural alterations by wrist-to-forearm ratio (WFR), epineural thickening, loss of fascicular anatomy, as well as classical signs and symptoms. The control group consisted of 42 wrists.Results
Women present with a greater WFR at first admission are affected more often bilaterally, and report less subjective pain intensity, while men report fewer nightly pain episodes at higher WFR. Loss of fascicular anatomy is three times more frequent in women. An increase in epineural thickness, loss of fascicular anatomy, and involvement of more than 1.5 fingers correlate significantly with WFR regardless of sex.Conclusion
Women differ significantly from men in terms of clinical presentation and ultrasound findings upon first diagnosis of CTS, which should be included in further diagnostic considerations.18.

Purpose of Review
Post-traumatic headache (PTH) is a common headache type after traumatic brain injury (TBI). There are no FDA approved medications for PTH, and it is unknown how medications can affect the brain’s ability to recover from TBI. Thus, we sought to examine the biopsychosocial factors that influence PTH and the non-pharmacologic treatments studied for headache treatment. We also sought to determine if there is literature examining whether the non-pharmacologic treatments influence the biopsychosocial factors. The non-pharmacologic treatments assessed included cognitive behavioral therapy (CBT), biofeedback, progressive muscle relaxation therapy (PMR), acupuncture, and physical therapy (PT).Recent Findings
Factors associated with prognosis in PTH may include the following: severity of TBI, stress, post-traumatic stress disorder, other psychiatric comorbidities, sociocultural and psychosocial factors, litigation, base rate misattribution, expectation as etiology, and chronic pain. There are few high quality studies on the non-pharmacologic treatments for PTH. Thermal and EMG biofeedback appear to have been examined the most followed by CBT. Studies did not have secondary outcomes examining the psychosocial factors related to PTH.Summary
Most of the behavioral studies involved a multi-modality intervention limiting the ability to assess the individual non-pharmacologic interventions we sought to study. There were very few randomized clinical trials evaluating the efficacy of non-pharmacologic interventions. Therefore, future research, which considers the noted biopsychosocial factors, is needed in the field to determine if these interventions reduce PTH.19.
Background
Despite high acceptance of manual medicine and proven positive for diseases of the locomotor system in particular, it is not recognized by or established in academic medicine. The reason for this might be the lack of a defined therapeutic target. No other medical field is defined by the diagnosis and treatment of clinical findings (somatic dysfunction).Methods
Based on an expert panel and relevant literature, somatic dysfunction, the development of functional diseases, and factors influencing their chronification are discussed and defined.Results
The diagnostic and therapeutic target of manual medicine is the functional disease as well as the underlying primary and secondary somatic dysfunction. Functional diseases of the locomotor system are characterized by the following cardinal symptoms: pain and deficits in function, participation, and activities. Somatic dysfunctions are the result of a discrepancy between burden and endurance of the structure and/or tissues. Somatic dysfunctions precede functional diseases and are the basis thereof.Discussion
In order to establish manual medicine in academic medicine, an accepted definition of functional diseases as diagnostic and therapeutic target is essential. Specific primary and secondary somatic dysfunctions are the cause for functional diseases and should therefore be diagnosed and treated. Other factors can also influence functional diseases and play an important role in their chronification. For chronic functional diseases, a multimodal interdisciplinary diagnosis is essential for the therapeutic strategy.20.
