#1
William J Mullally, Kathryn E Hall
OBJECTIVE: To determine if a brain MRI scan in patients with a diagnosis of migraine, who insist on the performance of imaging, is of more benefit in detecting clinically significant unsuspected structural abnormalities than would be expected by chance. METHODS: This prospective, observational, single center study was performed from January 1, 2010 to December 31,2012 and included 100 subjects with a diagnosis of migraine and a normal neurologic exam. A brain MRI scan was performed on all patients, solely at their request, to detect an unsuspected clinically significant structural lesion...

A 23-year-old East Indian woman with no significant medical history, except a depot-norethisterone enanthate injection taken 3 weeks prior to admission, presented with a gradually worsening headache for the past 5 days. She had no fever, vomiting, neck stiffness, focal weakness or rash, and examination was unremarkable with no focal neurological deficits. Vasculitic, thrombophilia and sepsis screens were normal. A brain CT scan showed a left parietal lobe venous infarct, secondary to a venous dural sinus thrombosis, with MRI and Magnetic Resonance Venogram (MRV) confirming a signal void...

OBJECTIVE: Pediatric headaches are a common presentation to emergency departments accounting for almost half a million annual visits. Providers are left with the difficult task of deciding who has a secondary headache etiology that warrants neuroimaging. METHODS: We conducted a retrospective case-control study. Patients from a pediatric neuro-oncology clinic database with brain cancer and a headache at presentation were identified as cases. Controls were patients from 2 local pediatric tertiary care emergency departments with a final diagnosis of headache after negative neuroimaging...

BACKGROUND: We previously derived the Ottawa Subarachnoid Hemorrhage Rule to identify subarachnoid hemorrhage (SAH) in patients with acute headache. Our objective was to validate the rule in a new cohort of consecutive patients who visited an emergency department. METHODS: We conducted a multicentre prospective cohort study at 6 university-affiliated tertiary-care hospital emergency departments in Canada from January 2010 to January 2014. We included alert, neurologically intact adult patients with a headache peaking within 1 hour of onset...

OBJECTIVE: The primary objective was to systematically evaluate the existing evidence base on magnesium in migraine prophylaxis. METHODS: The search for clinical trials published from 1990 to 2016 was separately conducted by AvL and FR using standard search terms as well as MeSh terms on PubMed and EMBASE. Randomized, double-blind, placebo-controlled trials investigating prophylactic magnesium administration in migraineurs aged 18-65 were considered eligible. In a mutual effort, the studies found were sorted and analyzed under consideration of the guidelines for controlled trials for drugs in migraine by the International Headache Society and using predefined eligibility criteria...

BACKGROUND: The natural history of cavernous malformations (CMs) has remained unclear. This lack of knowledge has made treatment decisions difficult. Indeed, the use of stereotactic radiosurgery is nowadays controversial. The purpose of this paper is to throw light on the effectiveness of Gamma Knife radiosurgery (GKRS) therapy. METHODS: The authors reviewed data collected from a prospectively maintained database. A total of 95 patients (57 female and 38 male) underwent GKRS for high-surgical-risk CMs...

Ebola virus is a filovirus that can cause fatal hemorrhagic fever (HF) and five distinct species exist that vary in terms of geographical distribution and virulence. Once the more virulent forms enter the human population, transmission occurs primarily through direct contact with infected body fluids and may result in significant outbreaks. The devastating has been the recent West African outbreak. Clinically, signs and symptoms are similar to those of the other VHFs [4]. The incubation period is 2-21days, followed by fever, headache, myalgia, diarrhoea, vomiting and dehydration; thereafter, there may be recovery or deterioration with collapse, neurological manifestations and bleeding, that can lead to a fatal outcome...

Approximately 80% of individuals infected with West Nile virus (WNV) are asymptomatic, and less than 1% suffer from neuroinvasion that can result in permanent neurological deficits or mortality. Our institution's location in southern California predisposes it to a sizable case volume of neuroinvasive WNV. A 2-year retrospective study was performed at the Olive View-UCLA Medical Center to identify patients with confirmed WNV infection with neuroinvasion. Patient demographics, neurological exam findings, and laboratory diagnostics were reviewed...

Cryopyrin-associated periodic syndromes (CAPS) are linked to one single gene mutations, however they are associated with 3 syndromes, which are, from the mildest to the most severe phenotype familial cold urticaria, Muckle-Wells syndrome and chronic, infantile, neurologic, cutaneous, articular (CINCA) syndrome also called neonatal-onset multisystem inflammatory disease (NOMID). Autosomic dominant inheritance is present in most cases but in CINCA/NOMID syndrome where neomutations are more common. Mutations in the gene encoding cryopyrin, NLRP3, are associated with deregulation of caspase-1 activity, excessive interleukin-1 production and an autoinflammatory syndrome, which in familial cold urticaria and Muckle-Wells syndrome may be triggered or worsened by exposure to coldness...

Imaging of sinonasal pathology may occur for assessment of rhinosinusitis or mass lesions. Rhinosinusitis is prevalent in up to 16% of the US population with annual economic burdens estimated at 22 billion dollars. Rhinosinusitis is characterized as acute or chronic based on symptom duration; if four or more episodes occur annually, the term recurrent acute rhinosinusitis (RARS) is used. In acute uncomplicated rhinosinusitis when inflammatory change remains in the paranasal sinuses and nasal cavity, imaging may not be required...

Intracranial melanotic schwannomas (IMSch) are extremely rare nerve sheath tumors with features of Schwann cells that produce melanin. After a thorough review of the available literature since 1967, we report not only the 20th case of IMSch but a comprehensive modern-era analysis of radiographic and histological key-points to be considered when diagnosing and treating patients with this rare known entity. This is the case of a 43 years-old woman who presented with severe headaches 9 years ago (2008). At that time, MRI of the brain showed a 1...
