The Challenges of Cervicogenic Headache.

PURPOSE OF REVIEW: The purpose of this manuscript is to illuminate the diagnostic challenges in patients who present with both headache and neck pain. RECENT FINDINGS: The differential diagnosis for headache and neck pain includes many conditions. Furthermore, cervical musculoskeletal abnormalities including head forward posture and myofascial trigger points may play an overlapping role in many of these conditions. Multiple headache disorders may be present within the same patient. A multidisciplinary team approach addressing all components of the headache may lead to better outcomes for these patients.

An Unusual Case of Post-Traumatic Headache Complicated by Intracranial Hypotension.

We present a case of post-traumatic headache complicated by intracranial hypotension resulting in an acquired Chiari malformation and myelopathy with syringomyelia. This constellation of findings suggest a possible series of events that started with a traumatic cerebral spinal fluid (CSF) leak, followed by descent of the cerebellar tonsils and disruption of CSF circulation that caused spinal cord swelling and syrinx. This unusual presentation of post-traumatic headache highlights the varying presentations and the potential sequelae of intracranial hypotension. In addition, the delayed onset of upper motor neuron symptoms along with initially normal head computerized tomography scan (CT) findings, beg the question of whether or not a post-traumatic headache warrants earlier magnetic resonance imaging (MRI).

Systematic Review of Preventive and Acute Treatment of Menstrual Migraine.

OBJECTIVE: The aim of this systematic review is to identify the efficacy of different categories of treatments for menstrual migraines as found in randomized controlled trials or open label studies with similar efficacy endpoints. BACKGROUND: Menstrual migraine is very common and approximately 50% of women have increased risk of developing migraines related to the menstrual cycle. Attacks of menstrual migraine are usually more debilitating, of longer duration, more prone to recurrence, and less responsive to acute treatment than nonmenstrual migraine attacks. METHODS: Search for evidence was done in 4 databases that included PubMed, EMBASE, Science Direct, and Web of Science. Eighty-four articles were selected for full text review by 2 separate readers. Thirty-six of the 84 articles were selected for final inclusion. Articles included randomized controlled and open label trials that focused on efficacy of acute and preventative therapies for menstrual migraine. Secondary analyses where excluded because the initial study population was not women with menstrual migraine. RESULTS: After final screening, 11 articles were selected for acute and 25 for preventive treatment of menstrual migraine. These were further subdivided into treatment categories. For acute treatment: triptans, combination therapy, prostaglandin synthesis inhibitor, and ergot alkaloids. For preventive treatment: triptans, combined therapy, oral contraceptives, estrogen, nonsteroidal anti-inflammatory drug, phytoestrogen, gonadotropin-releasing hormone agonist, dopamine agonist, vitamin, mineral, and nonpharmacological therapy were selected. Overall, triptans had strong evidence for treatment in both acute and short term prevention of menstrual migraine. CONCLUSIONS: Based on this literature search, of all categories of treatment for menstrual migraine, triptans have the most extensive research with strong evidence for both acute and preventive treatment of menstrual migraine. Further randomized controlled trials should be performed for other therapies to strengthen their use in the care of menstrual migraine patients.

Diffuse optical spectroscopy measurements of healing in breast tissue after core biopsy: case study.

Diffuse optical spectroscopy (DOS) has been used to monitor and predict the effects of neoadjuvant (i.e., presurgical) chemotherapy in breast cancer patients in several pilot studies. Because patients with suspected breast cancers undergo biopsy prior to treatment, it is important to understand how biopsy trauma influences DOS measurements in the breast. The goal of this study was to measure the effects of a standard core breast biopsy on DOS measurements of tissue deoxyhemoglobin, hemoglobin, water, and bulk lipid concentrations. We serially monitored postbiopsy effects in the breast tissue in a single subject (31-year-old premenopausal female) with a 37x18x20 mm fibroadenoma. A baseline measurement and eight weekly postbiopsy measurements were taken with a handheld DOS imaging instrument. Our instrument used frequency domain photon migration combined with broadband steady-state spectroscopy to characterize tissues via quantitative measurements of tissue absorption and reduced scattering coefficients from 650 to 1000 nm. The concentrations of significant near-infrared (NIR) absorbers were mapped within a 50 cm(2) area over the biopsied region. A 2-D image of a contrast function called the tissue optical index (TOI=deoxyhemoglobinxwaterbulk lipid) was generated and revealed that a minimum of 14 days postbiopsy was required to return TOI levels in the biopsied area to their prebiopsy levels. Changes in the TOI images of the fibroadenoma also reflected the progression of the patient's menstrual cycle. DOS could therefore be useful in evaluating both wound-healing response and the effects of hormone and hormonal therapies in vivo.
