ReviewNeuropathic Pain and Sickle Cell Disease: a Review of Pharmacologic Management.
Sickle cell disease (SCD) remains among the most common and severe monogenic disorders present in the world today. Although sickle cell pain has been traditionally characterized as nociceptive, a significant portion of sickle cell patients has reported neuropathic pain symptoms. Our review article will discuss clinical aspects of SCD-related neuropathic pain, epidemiology of neuropathic pain among individuals with SCD, pain mechanisms, and current and future potential pharmacological interventions. ⋯ Neuropathic pain in SCD is a complicated condition that often has a lifelong and significant negative impact on life; therefore, improved pain management is considered a significant and unmet need. Neuropathic pain mechanisms are heterogeneous, and the difficulty in determining their individual contribution to specific pain types may contribute to poor treatment outcomes in this population. Our review article outlines several pharmacological modalities which may be employed to treat neuropathic pain in SCD patients.

ReviewUnusual Brain MRI Findings in Patients Imaged for Headache: a Case Series.
We describe a series of cases with unusual brain MRI findings in patients who present with headache disorders. ⋯ Incidental findings in patients imaged for headache include the following: aneurysm, arachnoid cyst, cerebral vascular malformations, Arnold-Chiari malformations, empty sella turcica, gray matter heterotopias, mastoiditis, mega cisterna magna, meningioma, normal variants of cerebral circulation, paranasal sinus disease, pineal cyst, pituitary tumor, Rathke's cleft cyst, skull hyperostosis, and vestibular schwannoma. The most common abnormal MRI findings encountered in migraine are nonspecific white matter lesions. The current 2019 guidelines from the American College of Radiology and American Headache Society recommend against ordering neuroimaging in patients with a high probability of a primary headache disorder not typically associated with diagnostic imaging findings and who have normal neurologic exam in addition to no red flags in history. Often, unnecessary neuroimaging yields incidental findings, and this typically results in patient anxiety and further unnecessary testing. Detailed below are a series of cases in which unusual findings were found in patients presenting to our clinic for further evaluation of headache disorders. Imaging may have been done prior to presentation to us or by us due to concern for secondary causes.

Our objective is to describe the various neurologic manifestations of Behcet's syndrome with special attention to headache syndromes. ⋯ Most recent studies have focused on data collection to better characterize the relatively rare disorder of neuro-Behcets (NBD). In patients with Behcet's disease (BD) who are experiencing headache, most are primary headache disorders, specifically tension type or migraines. Worsening headache can, however, be a sign of increased Behcets disease activity. Behcet's disease is a chronic, systemic, inflammatory disorder of unknown etiology. The prevalence of BD is most notable in countries along the ancient Silk Road, particularly the Middle East. BD occasionally has neurologic manifestations, further categorized into parenchymal and non-parenchymal syndromes. Headache is the most frequently reported neurological symptom of BD. Primary headaches are the most common headache type among patients with BD with comorbid headache disorders with debate regarding whether migraine or tension-type headache is most prevalent. Of the secondary causes of headache in BD, cerebral venous thrombosis is the most common.

The purpose of this review is to summarize the up-to-date pain management options and recommendations for the challenging disease, endometriosis. ⋯ The mainstays of endometriosis advances of both surgical and medical management continue to evolve. Experimental pharmaceuticals include Gestirone, and aromatase inhibitors have shown promise but are still under scrutiny. Surgical techniques include laparoscopic uterosacral nerve ablation/resection and presacral neurectomy. No studies have directly compared medical versus surgical management, and as such, no one treatment modality can be recommend as superior to the other. Patients may initially be given a medical diagnosis and treated with nonsteroidal anti-inflammatory drugs, neurolepitcs, OCP, GNRH agonists/antagonists, and Danazol. Assessing the success of these regimens has proved difficult. Surgical management relies on various methods including excision/ablation of the lesions, nerve ablation, neurectomy, hysterectomy, and oophorectomy.

In this review, we examine reported cases of cephalgia alopecia including the initial case report from 2006. The goal is to review the clinical description, pathophysiology, diagnosis, and treatment of cephalgia alopecia. ⋯ The pathophysiology of the headache and hair loss in cephalgia alopecia is believed to be related to neuroregulation of skin and nerve. It is hypothesized that the headache causes recurrent activation of trigeminal and upper cervical branches that innervate the hair cells. The repetitive activation of C fibers results in depletion of substance P and calcitonin gene-related peptide (CGRP), which leads to loss of hair growth promotion and disruption of immune system regulation. A case report suggests that cephalgia alopecia and nummular headache with trophic changes may represent a spectrum of disease involving head pain and cutaneous changes. Cephalgia alopecia is a rare headache disorder described as recurrent burning, stabbing head, and neck pain that is followed by hair loss in the corresponding region of the scalp. The mainstay treatment for both pain and hair loss is OnabotulinumtoxinA (onabotA). A patient's clinical history and response to onabotA treatment is used to make the diagnosis. Future research is needed to examine the hypothesized disease continuum of head pain and cutaneous changes. It will also be beneficial to assess if the grid-like onabotA technique used in nummular headache is effective in cephalgia alopecia. In addition, further studies are needed to assess the proposed pathophysiology.
