RESUMEN
Cattle encephalon glycoside and ignotin (CEGI) injection is a compound preparation formed by a combination of muscle extract from healthy rabbits and brain gangliosides from cattle, and it is generally used as a neuroprotectant in the treatment of central and peripheral nerve injuries. However, there is still a need for high-level clinical evidence from large samples to support the use of CEGI. We therefore carried out a prospective, multicenter, randomized, double-blind, parallel-group, placebo-controlled study in which we recruited 319 patients with acute cerebral infarction from 16 centers in China from October 2013 to May 2016. The patients were randomized at a 3:1 ratio into CEGI (n = 239; 155 male, 84 female; 61.2 ± 9.2 years old) and placebo (n = 80; 46 male, 34 female; 63.2 ± 8.28 years old) groups. All patients were given standard care once daily for 14 days, including a 200 mg aspirin enteric-coated tablet and 20 mg atorvastatin calcium, both taken orally, and intravenous infusion of 250-500 mL 0.9% sodium chloride containing 40 mg sodium tanshinone IIA sulfonate. Based on conventional treatment, patients in the CEGI and placebo groups were given 12 mL CEGI or 12 mL sterile water, respectively, in an intravenous drip of 250 mL 0.9% sodium chloride (2 mL/min) once daily for 14 days. According to baseline National Institutes of Health Stroke Scale scores, patients in the two groups were divided into mild and moderate subgroups. Based on the modified Rankin Scale results, the rate of patients with good outcomes in the CEGI group was higher than that in the placebo group, and the rate of disability in the CEGI group was lower than that in the placebo group on day 90 after treatment. In the CEGI group, neurological deficits were decreased on days 14 and 90 after treatment, as measured by the National Institutes of Health Stroke Scale and the Barthel Index. Subgroup analysis revealed that CEGI led to more significant improvements in moderate stroke patients. No drug-related adverse events occurred in the CEGI or placebo groups. In conclusion, CEGI may be a safe and effective treatment for acute cerebral infarction patients, especially for moderate stroke patients. This study was approved by the Ethical Committee of Peking University Third Hospital, China (approval No. 2013-068-2) on May 20, 2013, and registered in the Chinese Clinical Trial Registry (registration No. ChiCTR1800017937).

RATIONALE: Co-occurrence of headache and arrhythmia is not rare. However, their causal relationship remains unclear. Here, we described a case of migraine-like headache relieving with pacemaker implantation. Our case study indicates that arrhythmia is causal for migraine-like headache, which, to our knowledge, has never been reported. PATIENT CONCERNS: A 63-year-old woman patient suffered from paroxysmal headache with a visual aura presenting like migraine for 2 years. No ophthalmic or neurological disorder was found, but cardiac examination detected bradycardia, which was confirmed by 24-hour dynamic electrocardiogram (DCG) revealing sinus bradycardia mixed with ventricular premature beats and supraventricular tachycardia. Transcranial doppler (TCD) detected an equal echo flat plaque on the anterolateral wall of the common carotid artery (CA) bifurcation. DIAGNOSIS: Migraine-like headaches secondary to arrhythmia. INTERVENTIONS: The patient underwent pacemaker implantation. OUTCOMES: Both visual aura and headache were resolved following pacemaker implantation. LESSONS: To the best of the authors' knowledge, we are the first to report migraine-like headache as a secondary symptom of arrhythmia. Arrhythmia may aggravate insufficient blood supply to the brain due to CA lesion and induce a migraine-like headache. This case study indicated that pacemaker implantation could be a fundamental treatment for migraine-like headaches caused by cardiac arrhythmia.

RATIONALE: Clinically mild encephalitis/encephalopathy with a reversible splenial lesion of the corpus callosum (MERS) is a recently identified clinically and radiologically distinct syndrome. Clinical symptoms and lesions on the magnetic resonance imaging (MRI) often disappear in 1 week or a few weeks. However, MERS manifesting as a severe clinical course with significant sequela has not yet been reported. PATIENT CONCERNS: A 42-year-old male presented with a 3-day history of headache, fever, and irrational speech. Physical examination showed a body temperature of 39.5°C, dysarthria, dyscalculia, recent memory disturbance, and otherwise normal vital signs. The patient developed status epilepticus and progressive consciousness disturbance. MRI showed abnormal patchy signals in the splenium of the corpus callosum. DIAGNOSIS: The clinical feature and the characteristic of MRI are mostly consistent with MERS. At the same time, we made a differential diagnosis by testing the NMDARAb, AMPA1Ab, AMPA2Ab, LG1Ab, CASPR2Ab, GABABRAb in CSF and serum. INTERVENTIONS: The subject was treated with ganciclovir, antiepileptic, and antipyretic therapy. OUTCOMES: The subject was living a virtually normal life with persistent mild memory disturbance. MRI showed that the abnormal signals in the splenium of the corpus callosum had disappeared, but hyperintensity on T2-weighted and FLAIR imaging was noted in the centrum semiovale. LESSONS: MERS is a rare clinicoradiological syndrome, which can manifest as severe symptoms as well. Early diagnosis and treatment should be emphasized, and the diagnostic value of MRI is highlighted. Clinicians should be alert to the potential sequela.

Migraine is a debilitating disorder characterized by recurrent headache arising from neurovascular dysfunction. Despite recent progress in migraine research, the exact mechanisms underpinning migraine are poorly understood. Furthermore, it is difficult to develop an animal model of migraine that resembles all symptoms of patients. In this study, we established a novel animal model of migraine induced by epidural injection of calcitonin gene-related peptide (CGRP), and examined climbing hutch behavior, facial-grooming behavior, body-grooming behavior, freezing behavior, resting behavior, and ipsilateral hindpaw facial grooming behavior of rats following CGRP injection. CGRP significantly reduced climbing hutch behavior, and face-grooming behavior, and increased immobile behavior. We also found that the P15 and P85 percentile range of behavioral data exhibited a high positive rate (83.3%) for establishing the model with less false positive rate. Our results verified that the rat model of migraine induced by CGRP featured many behaviors of migraine patients demonstrated during migraine attacks. Our findings suggest that this new model can be a useful tool for understanding the pathophysiology of migraine and studying novel therapeutic strategies for the treatment of migraine.

Despite recent research focus on the association between Helicobacter pylori (H. pylori) infection and multiple sclerosis (MS) there is no consensus about the findings. To obtain a more comprehensive estimate of the association we conducted a meta-analysis to determine the prevalence of H. pylori infection in MS patients and healthy controls. Pubmed and EMBASE were searched to identify eligible studies. Nine studies were selected for inclusion, involving 2806 cases (1553 patients with MS and 1253 controls). Overall, the prevalence of H. pylori infection in MS patients was lower than that in control groups (24.66% vs. 31.84%, OR=0.69, 95% CI: 0.57-0.83, P<0.0001). Subgroup analysis revealed that the levels of H.pylori infection among MS patients were lower than for control subjects in Western countries (11.90% vs. 16.08%, OR=0.63, 95% CI: 0.43-0.91, P=0.01), but were not statistically significant in Eastern countries (39.39% vs. 43.82%, OR=0.79, 95% CI: 0.55-1.14, P=0.20). Our data show that H. pylori infection and MS is negatively correlated, especially in Western countries. Whether H. pylori infection is a protective factor against MS risk should thus be addressed in large-scale and prospective studies.

Nummular headache (NH) is defined as a focal head pain that is exclusively felt in a small area, which is typically 1-6 cm in diameter. Neurological examinations are normal in all patients, but this report describes a new variant. A patient was identified who presented with focal head pain that was approximately 8 cm in diameter and bitrigeminal hyperalgesia on neurological examination. Treatment with carbamazepine provided significant analgesic relief in terms of both the frequency and intensity of pain. The findings enlarge the clinical diversity of this headache disorder. The pathogenic mechanisms of NH may be similar to trigeminal neuralgia in particular patients.
