Migraine is one of the most prevalent and disabling neurological disease, but the current pharmacotherapies show limited efficacy and often accompanied by adverse effects. Acupuncture is a promising complementary therapy, but further clinical evidence is needed. The influence of acupuncture on migraine is not an immediate effect, and its mechanism remains unclear. This study aims to provide further clinical evidence for the anti-migraine effects of acupuncture and explore the mechanism involved. A randomized controlled trial was performed among 10 normal controls and 38 migraineurs. The migraineurs were divided into blank control, sham acupuncture, and acupuncture groups. Patients were subjected to two courses of treatment, and each treatment lasted for 5 days, with an interval of 1 day between the two courses. The effectiveness of treatment was evaluated using pain questionnaire. The functional magnetic resonance imaging (fMRI) data were analyzed for investigating brain changes induced by treatments. Blood plasma was collected for metabolomics and proteomics studies. Correlation and mediation analyses were performed to investigate the interaction between clinical, fMRI and omics changes. Results showed that acupuncture effectively relieved migraine symptoms in a way different from sham acupuncture in terms of curative effect, affected brain regions, and signaling pathways. The anti-migraine mechanism involves a complex network related to the regulation of the response to hypoxic stress, reversal of brain energy imbalance, and regulation of inflammation. The brain regions of migraineurs affected by acupuncture include the lingual gyrus, default mode network, and cerebellum. The effect of acupuncture on patients' metabolites/proteins may precede that of the brain.

The results of surgical bypass and endarterectomy in Takayasu's arteritis (TA) were reported to be poor compared to usual atherosclerosis patients. However, if ischemic symptoms due to occlusive disease were severe, surgical procedures were inevitable. We report surgical experience of 5 patients with TA. Five women (ranged from 26 to 58 yr) were operated between June 1998 and May 2004. Three patients showed occlusion of main branches of aortic arch and had symptoms of cerebral ischemia. One patient showed near total occlusion in the midabdominal aorta and had symptoms of orthopnea and uncontrolled hypertension. One patient showed total occlusion of abdominal aorta at the level of aortic bifurcation and had a symptom of severe claudication on both legs. Bypasses from the ascending aorta to the carotid artery were performed in 3 cases. Bypass from the thoracic aorta to the left common iliac artery was performed in one case and endarterectomy of abdominal aorta in one case. The ischemic symptoms related with arterial occlusion were resolved after surgery. And the symptoms of cardiac failure disappeared. The symptomatic TA frequently required arterial reconstruction. The symptomatic improvement and excellent mid-term patency could be expected after arterial reconstruction and endarterectomy.

OBJECTIVETo summarize the clinical presentation, pathogenesis, neuroimaging, treatment, and outcome of stroke-like migraine attacks after radiation therapy (SMART) syndrome, and to propose diagnostic criteria for this disorder.

DATA SOURCESWe searched the PubMed database for articles in English published from 1995 to 2015 using the terms of "stroke-like AND migraine AND radiation." Reference lists of the identified articles and reviews were used to retrieve additional articles.

STUDY SELECTIONData and articles related to late-onset effects of cerebral radiation were selected and reviewed.

RESULTSSMART is a rare condition that involves complex migraines with focal neurologic deficits following cranial irradiation for central nervous system malignancies. The recovery, which ranges from hours to days to weeks, can be partial or complete. We propose the following diagnostic criteria for SMART: (1) Remote history of therapeutic external beam cranial irradiation for malignancy; (2) prolonged, reversible clinical manifestations mostly years after irradiation, which may include migraine, seizures, hemiparesis, hemisensory deficits, visuospatial defect, aphasia, confusion and so on; (3) reversible, transient, unilateral cortical gadolinium enhancement correlative abnormal T2 and fluid-attenuated inversion recovery signal of the affected cerebral region; (4) eventual complete or partial recovery, the length of duration of recovery ranging from hours to days to weeks; (5) no evidence of residual or recurrent tumor; (6) not attributable to another disease. To date, no specific treatment has been identified for this syndrome.

CONCLUSIONSSMART is an extremely rare delayed complication of brain irradiation. However, improvements in cancer survival rates have resulted in a rise in its frequency. Hence, awareness and recognition of the syndrome is important to make a rapid diagnosis and avoid aggressive interventions such as brain biopsy and cerebral angiography.

OBJECTIVETo analyzed the characteristics of migrainous vertigo (MV), a kind of paroxysmal vertigo, in order to demonstrate the extent of damage and dysfunction in MV and to judge whether MV is peripheral or central vertigo.

METHODSTwenty-two cases of acute (5 cases) or subacute (17 cases) MV were examined with oto-neurological tests, spontaneous nystagmus, positional nystagmus and auditory tests.

RESULTSThere were 6 males and 16 females. Among those patients, 15 had migraine, 17 motion sickness, 15 family history of migraine or motion sickness, 1 visual aura, 7 motion intolerance (vertigo from head movement and body movement), 4 photophobia, 6 phonophobia and 5 vertigo from insomnia and emotion. There were likely to have vertigo in menstrual period in 2 cases. The duration of vertigo lasted from minutes to days. For pure-tone audiometric, 9 were normal which from mild to moderate hearing loss. Three cases had abnormal high frequency ABR bilaterally and 10 abnormal unilaterally. Subjective visual vertical were normal in all of the cases. Vestibular evoked myogenic potentials were abnormal in 14 cases (13 had low amplitude and 1 had longer latency of P13 wave). Bithermal caloric test was abnormal in 3 cases and 11 had abnormal ocular movement (9 with low gain of optokinetic nystagmus, 1 with overshoot in saccade and 1 with vertical nystagmus after head shaking), in which 10 had abnormal high frequency ABR and 1 was normal.

CONCLUSIONSMV could be peripheral or central vertigo and MV should be included in the differentiation of peripheral and central vertigo.

OBJECTIVETo investigate the role of transient receptor potential melastatin 8 (TRPM8) channels in migraine mechanism in rats by measuring the changes in expression of TRPM8 in the trigeminal nerve of rats with migraine.

METHODSTwenty male Sprague-Dawley rats were randomly and equally divided into a blank control group and a model group. Nitroglycerin (10 mg/kg) was injected subcutaneously in the back of the neck once a week for 5 weeks, to prepared a rat model of migraine without aura. Normal saline was injected subcutaneously instead of nitroglycerin in the control group. At 4 hours after the final injection, behavior scoring of all rats was performed, and then the trigeminal nerve ganglions of rats in both groups were collected for measurement of expression of N-methyl-D-aspartate receptor (NMDAR), protein kinase A (PKA), and TRPM8 using immunohistochemical staining, immunofluorescence, and Western blot, respectively.

RESULTSThe behavior score in each week during the rat model preparing was significantly higher in the model group than in the control group (P<0.05). The expression of NMDAR, PKA, and TRPM8 in the model group was significantly higher than in the control group (P<0.01). Both the behavior score and the expression of NMDAR were positively correlated with the expression of TRPM8 (r=0.822 and 0.794 respectively; P<0.01).

CONCLUSIONSTRPM8 may be involved in migraine mechanism probably by activation of the NMDAR pathway.

OBJECTIVE: To analyze two groups of patients with migrainous vertigo (MV )and vertigo resulting from posterior circulation ischemia (PCIV) and investigate the differential diagnosis between them. METHOD: There were 60 patients with MV and 64 patients with PCIV. Clinical tests include high risk factors of posterior circulation ischemia (PCI), cerebral MRI, ocular motion and high stimulating rate ABR. RESULT: Among 64 patients with PCIV, 29 had abnormal blood pressure and 14 had abnormal blood fat and/or pathoglycemia; 37 had abnormality in cervical vascular ultrasound; 14 suffered from amaurosis or dizziness upon fast getting up. Twenty two had abnormal high stimulating rate ABR and 4 had cerebral lacunar infarction in MRI. As for 60 patients with MV, 45 suffered from motion sickness; 20 were sensitive to motion; 32 had photophobia and (or) phonophobia; 45 had migraine; 16 had abnormal ocular motion function; 3 had abnormal cerebral MRI and 40 had abnormal results in high stimulating rate ABR. The percentage of abnormal high stimulating rate ABR in MV and PCIV were 53% (22/42) and 67% (40/60) respectively. CONCLUSION The mean age of MV is younger than that of PCIV. Female is more prone to MV than male (2.75 : 1. 00); the sex difference in PCIV is lesser (1.46 : 1.00). Motion sickness, motion sensitivity, photophobia and (or) phonophobia are principal differential highlights to MV. The major characteristics of PCIV include abnormal blood pressure, abnormal blood fat, pathoglycemia and arteriosclerosis. Vestibular function tests could not serve as a differential point; Cerebral MRI might be helpful to differential diagnosis. The results of high stimulating rate ABR is not a differential point between PCIV and MV, but it might play a role in differentiating other kinds of vertigo.

OBJECTIVETo investigate the clinical and genetic characteristics of three Chinese Meniere's disease (MD) families and decipher the mechanism of MD further.

METHODSPersonal and family medical evidence of hearing loss, vestibular symptoms, and other clinical abnormalities of the participants were identified, clinical and genetic features were analyzed. Targeted 307 genes capture and high-throughput sequencing were performed on the two ascertained members of family 1007184.

RESULTSEight patients from these three families showed post-lingual sensorineural hearing loss, six women and two men were involved. Age of onset in these affected members concentrated in the middle age, with the average age of 39.3 years old. Among them, patients from 1407278 were accompanied by migraine. All of the three probands presented as recurrent vertigo firstly, and then fluctuated hearing loss showed up, accompanying by tinnitus and ear fullness feeling. The hearing loss manifested as late-onset, low frequency-involved pattern, with subsequent gradual progression from moderate to severe level. Some of the patients progressed to severe level involving all frequencies at higher ages. In addition, most of the cases showed revitalization. Four cases received vestibular function tests, three of which had varying dysfunction of vestibular function, while the other one had normal vestibular function. Patients who had abnormal vestibular function showed much more severe hearing impairment. The three-generation family 1007193 had an autosomal recessive genetic characteristics, family 1007184 showed autosomal dominant inheritance of characteristics, family 1407278 were either autosomal dominant or X-linked dominant pattern. Through target genes capture high-throughput sequencing technology, we identified two candidate variants in the two members of family 1007184, named c. 2057G>A in EGFLAM and c. 1961C>T in ITGA8.

CONCLUSIONMeniere's disease has some genetic and familial aggregation in Chinese population, but its complex genetic pathogenic mechanisms need further study.

We report on an angioedema patient with a genetic defect in complement 1 inhibitor, manifesting migraine-like episodes of headache, effective prophylaxis with Danazol, and triptan for a treatment of acute clinical episode. The patient was 44-yr-old Korean man with abdominal pain and headache, who was brought into the Emergency Department of Seoul National University Hospital, Seoul. He suffered from frequent attacks of migraine-like headache (3-7 per month), pulsating in nature associated with nausea. Severities were aggravated by activity and his headache had shown recent progression with abdominal pain. No remarkable findings were observed on radiologic examination, brain magnetic resonance images and intracranial and extracranial magnetic resonance angiography. Danazol 200 mg every other day was subsequently used. Following administration of Danazol, symptoms showed improvement and the patient was discharged. While taking Danazol, the migraine-like episodes appeared to be prevented for about 2 yr. At the eighth month, he suffered a moderate degree of migraine-like headache; however, administration of naratriptan 2.5 mg resolved his problem. A case of genetic defect of C1-INH deficiency presented with headache episodes, and was controlled by Danazol and triptan. It suggests that pathogenic mechanism of headache in hereditary angioedema may be mediated by the neurogenic inflammatory-like physiology of migraine.
