Cabral G, Serôdio M, Krupka D, Ferreira VM, Calado S, Baptista MV. Are there differences between patients with unifocal nummular headache and those who progress to bifocal nummular headache? A retrospective observational study. Headache 2024. [PMID: 38860505 DOI: 10.1111/head.14751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 03/28/2024] [Accepted: 05/13/2024] [Indexed: 06/12/2024]
Abstract
OBJECTIVES This retrospective observational cohort study aimed to compare clinical characteristics and treatment responses in patients exclusively experiencing unifocal nummular headache (NH) with those who develop the bifocal variant. METHODS A retrospective study was conducted on patients diagnosed with NH who attended a neurology (headache) outpatient clinic between January 2018 and December 2022. The cohort was divided into two groups: Group 1, exclusive unifocal NH; and Group 2, those developing a secondary focal area of pain, i.e., bifocal NH. Data were collected on demographic characteristics, clinical features, other headache comorbidities, and treatment-related information. RESULTS A total of 23 patients were included in this study: 12 were categorized as unifocal NH (Group 1) and 11 as bifocal NH (Group 2). There were no differences between the two groups in terms of demographic characteristics, clinical features, or treatment response. Nonetheless, patients with bifocal NH exhibited spontaneous remission rates in the first pain area when compared to the unifocal NH group, with statistically significant differences (36% vs. 0%, p = 0.020). CONCLUSION In our sample, patients with bifocal NH demonstrated spontaneous remission rates in the initial pain area, a phenomenon not observed in patients with unifocal NH. It is worth noting the limited sample size in the present study, highlighting the need for larger cohorts to validate and further explore our findings.

Abstract
BACKGROUND Nummular headache and epicrania fugax are two primary headaches that fall under the heading of epicranial headaches. METHODS This article reviews the epidemiological and clinical features of nummular headache and epicrania fugax, proposed pathogenic mechanisms and state-of-the-art management, according to the literature. RESULTS AND CONCLUSIONS Nummular headache and epicrania fugax are generally viewed as rare headache disorders, but no population-based epidemiological data are available. Nummular headache is characterized by continuous or intermittent head pain, which remains circumscribed in a round or oval area of the scalp, typically one to six centimeters in diameter. Epicrania fugax manifests with brief paroxysms of pain that move along the surface of the head, following a linear or zigzag trajectory through different nerve territories. Nummular headache and epicrania fugax are mostly primary headaches, but some secondary cases have been reported. The pathogenesis of these headaches is not fully understood. Nummular headache could probably originate in epicranial tissues or adjacent intracranial structures, while the origin of epicrania fugax could be extracranial or intracranial. Diagnostic assessment requires careful examination of the symptomatic areas. Underlying disorders should be excluded by additional investigations, including neuroimaging and appropriate blood tests. No controlled clinical trials have been conducted in nummular headache or epicrania fugax. Analgesics and anti-inflammatory drugs, botulinum toxin and gabapentin are currently the most recommended treatment options for nummular headache. In epicrania fugax, the most used treatments are gabapentin, lamotrigine, and other antiseizure medications.

Abstract
Side-locked headaches are a common symptom having a wide-ranging differential. Unchanging in laterality, these headaches can represent neuralgias, trigeminal autonomic cephalgias, ophthalmologic disorders, otolaryngologic and craniofacial disorders, vascular disorders, and malignancy. In rarer situations, they have presented secondary to neurosurgical or dermatologic considerations. Loss of cranial nerves and visual changes warrant additional evaluation.

Abstract
PURPOSE This article provides an overview of a diverse group of primary headache disorders that are categorized in the International Classification of Headache Disorders, 3rd Edition (ICHD-3), as "other primary headache disorders." This article provides clinicians with a distilled understanding of the diagnoses and their epidemiology, pathophysiology, and management. RECENT FINDINGS Cough-induced headache requires neuroimaging to exclude posterior fossa pathology and recently has been reported as a common symptom in patients with CSF-venous fistula. Clinical overlap is observed between patients with primary exercise headache and primary headache associated with sexual activity. Patients with recurrent thunderclap headache associated with sexual activity should be presumed to have reversible cerebral vasoconstriction syndrome until proven otherwise. De novo external-pressure headache is a common sequela among health care workers using personal protective equipment during the COVID-19 pandemic. New daily persistent headache is an important mimicker of chronic migraine or chronic tension-type headache and is distinguished by a daily-from-onset progression of persistent headache; a treatment-refractory course is often observed, and early involvement of a multidisciplinary team, including a psychotherapist, is advised. SUMMARY Patients with primary headache disorders that are classified as "other primary headache disorders" have presentations with unique diagnostic and management considerations. The disorders are highly recognizable, and an appreciation of the diagnoses will aid clinicians in providing safe and effective care for patients presenting with headache.

Abstract
Temporomandibular disorders (TMD) is a chronic pain disease affecting 4-60% of general population. Its suggested etiology includes mechanical overloading to related structures, psychosocial factors, and genetic vulnerability. However, its pathogenesis is yet to be fully understood, especially in cases with a higher level of pain and more associated comorbidities. Recently chronic systemic inflammation and possible autoimmunity has been indicated in several pain conditions as the underlying mechanism of chronicity but this aspect has not been rigorously investigated in TMD. This article focuses on analyzing the levels of cytokines, chemokines, autoantibodies and nonspecific inflammatory markers and comparing their levels according to pain severity and duration in 66 female TMD patients in their 20 s and investigating their association with clinical indices of TMD and comorbidities. The high pain disability group showed decreased range of jaw function and more pain on palpation of capsule areas compared to the low pain disability group. Comorbidities such as anxiety and sleep disturbance were also significantly more prevalent. The level of IL-8 and IgG were significantly higher in the high pain disability group. IL-2, -8, -13, IFN- γ, RANTES, PGE2, and thrombopoietin levels showed a significant effect on indices reflecting jaw function, generalized pain intensity, and health related quality of life. Such results imply that longer pain duration and higher pain intensity is associated with higher levels of systemic inflammation suggesting the possible role of immunologic disturbance as an underlying factor of chronic TMD pain and warranting further investigation for its consideration in diagnosis and treatment.

Abstract
PURPOSE OF REVIEW The purpose of this manuscript is to shed light on systematic work-up of a diagnostic challenge such as nummular headache (NH), and to summarize the relevant literature on NH. RECENT FINDINGS The specific nature of the shape of the pain site is usually characteristic of NH. Multiple modalities of investigation including succinct imaging are necessary to successfully rule out other similar conditions. A 26-year-old female patient of Asian-Indian origin presented to the clinic with the chief complaint of chronic persistent left parietal headache for more than 10 years, which has been worsening over the past few days with no specific identifiable trigger. The diagnosis of nummular headache is challenging and confusing due to the rare occurrence and inadequate references in the literature. Appropriate imaging was done, which revealed no pathology that could explain the headache presentation. These findings are consistent with our diagnosis of nummular headache, and helped in the successful management of the case.

Abstract
BACKGROUND Head trauma has been described as a precipitating event in Nummular Headache (NH). We aimed to describe the largest NH published series and compare characteristics between idiopathic and post-traumatic cases. METHODS Patients attended in a Headache Unit in a tertiary hospital (January 2008-January 2018). NH diagnosed according to International Classification of Headache Disorders (ICHD) criteria. We prospectively considered clinical and epidemiological data, comparing idiopathic cases with those precipitated by a cranial trauma. RESULTS We included 225 patients (145 women, 80 men) with NH. Median latency between onset and diagnosis was 10 months (IQR: 5-24). Symptomatic treatment was used in 190 patients (84.4%) among which 142 (74.7%) experienced response to it. Preventive treatment was necessary in 127 patients (51.4%), among which 95 (74.8%) achieved response. 29 patients (23 women, 6 men) described a head trauma related to beginning of pain. When comparing groups with or without previous trauma, age of onset was higher among post-traumatic patients (59.9 ± 17.4 vs 48.1 ± 18 years, p: 0.001). Allodynia upon palpation was encountered more frequently in trauma triggered painful areas (53.3% vs. 32.7%, p: 0.02). No other clinical characteristics differences were observed. CONCLUSION Cranial trauma is not a rare trigger of NH. Patients with post-traumatic forms are older and the presence of allodynia is more frequent.

Abstract
Nummular headache (NH) is an unusual disorder attributed to a dysfunction of the epicranial nerves. We report a new series of cases, highlighting some clinical features, the association with other headaches, and the therapeutic response. Data of patients with NH, fulfilling ICHD-3 criteria, observed in a Headache Outpatient clinic during 5 years, were retrieved from records. Response to onabotulinumtoxinA was recorded prospectively and evaluated with a Headache Impact Test (HIT). Twenty-four patients, aged 53.8 (±14.6) years at diagnosis, 13 women, had definitive ( N = 21) or probable ( N = 3) NH for an average of 2.4 years. Headache was consistently localized, more frequently extratrigeminal ( N = 15) and parietal, and confined to the scalp. Pain was unremitting since onset in 58.3% of mild-to-moderate severity often with superimposed paroxysms (66.7%) and local allodynia (70.8%). In five cases, there was a possible precipitant. Thirteen patients reported other headaches, preceding NH by 8.2 years. In eight persistent cases, there was a significant improvement on HIT, after onabotulinumtoxinA. Despite its persistence, NH may go unrecognized for years. It often follows other headache types and has some tropism for hair-covered regions of the scalp. OnabotulinumtoxinA seems effective in persistent cases.

Abstract
The overview is dedicated to the neuroimmunological mechanisms of headache development and chronification. Based on the analyzed data, the authors determined the relationship between immunological parameters and duration, intensity and other characteristics of this disease. These findings confirm that immunocompetent cells can be used as headache biomarkers and predictors of treatment efficacy. Questions about the role of separate parts of the immune system in the development and maintenance of a headache require further research. Studies of humoral immunity appeared to be very promising.

Abstract
Complex regional pain syndrome (CRPS) is a painful, disabling, chronic condition whose etiology remains poorly understood. The recent suggestion that immunological mechanisms may underlie CRPS provides an entirely novel framework in which to study the condition and consider new approaches to treatment. Using a murine fracture/cast model of CRPS, we studied the effects of B-cell depletion using anti-CD20 antibodies or by performing experiments in genetically B-cell-deficient (μMT) mice. We observed that mice treated with anti-CD20 developed attenuated vascular and nociceptive CRPS-like changes after tibial fracture and 3 weeks of cast immobilization. In mice with established CRPS-like changes, the depletion of CD-20+ cells slowly reversed nociceptive sensitization. Correspondingly, μMT mice, deficient in producing immunoglobulin M (IgM), failed to fully develop CRPS-like changes after fracture and casting. Depletion of CD20+ cells had no detectable effects on nociceptive sensitization in a model of postoperative incisional pain, however. Immunohistochemical experiments showed that CD20+ cells accumulate near the healing fracture but few such cells collect in skin or sciatic nerves. On the other hand, IgM-containing immune complexes were deposited in skin and sciatic nerve after fracture in wild-type, but not in μMT fracture/cast, mice. Additional experiments demonstrated that complement system activation and deposition of membrane attack complexes were partially blocked by anti-CD20+ treatment. Collectively, our results suggest that CD20-positive B cells produce antibodies that ultimately support the CRPS-like changes in the murine fracture/cast model. Therapies directed at reducing B-cell activity may be of use in treating patients with CRPS.

Abstract
Nummular headache (NH) is a newly categorized headache disorder characterized by a consistent clinicographics in each attack. Currently, it is considered as a primary headache disorder due to epicranial neuralgia but the pathomechanism is still unknown. We report a woman, whose recurrent NH subsided after trans-sphenoidal surgery for her pituitary oncocytoma. The recovery of NH in this patient encourages the central mechanism for NH occurrence. After a review of literature concerning, NH and intracranial secondaries we propose that central NH is a referral pain from pain-sensitive structures, such as meninges, superimposing by pre-existing lower pain threshold or pain modulation.
