Post-concussion syndrome (PCS) is defined as the presence of 3 or more of the following signs and symptoms after experiencing head injury such as headache, dizziness, fatigue, irritability, insomnia, difficulty of concentration or memory difficulty. In Ethiopia, even though there was no research conducted on post-concussion syndrome, it is common health problems after experiencing head trauma that affect the productive age group, which directly or indirectly influences the development of the country. ⋯ About 41.5% of study participants had at least three symptoms of PCS. Occupation, cause of injury and location of injury were significantly associated with the occurrence of PCS.

Several studies examined headaches as a symptom of brain neoplasms. Nevertheless, very few studies attempted to specifically evaluate the role of headaches as a risk factor. This study aimed to investigate the risk of migraine occurrence in the preceding years among patients diagnosed with brain tumors and unaffected controls. ⋯ This is the first report demonstrating the occurrence of brain tumors to be associated with a prior migraine history, for both men and women, in a population-based study.

Cognitive dysfunction has recently gained attention as a significant problem among migraine sufferers. All of the clinical studies show poor cognitive performance during migraine attacks, though, the interictal data are conflicting. Migraineurs show impaired cognitive function interictally in most of the clinic-based studies. ⋯ Longitudinal studies do not suggest progressive cognitive decline over time in migraine patients. Preventive medications and comorbid disorders such as depression and anxiety can impact cognitive function, but cannot fully explain the cognitive impairment in migraine. In contrast to migraine, tension type or cluster headache are not associated with cognitive impairment, at least during headache-free periods.

Review
The publication trend of neuropathic pain in the world and China: a 20-years bibliometric analysis.
There has been tremendous change on neuropathic pain research in the past 20 years in China and around the world. We analyzed the global trend of neuropathic pain research and compared China's quantity and quality of neuropathic pain-related publications with other developed countries. ⋯ Global neuropathic pain research increased rapidly during the 1998 to 2017 period. The USA was still the leader of neuropathic research. Although China had made great achievements, there was a significant gap in the high-quality studies between China and other leading countries.

Multicenter Study
Headache attributed to aeroplane travel: the first multicentric survey in a paediatric population affected by primary headaches.
This multicentric survey investigates the prevalence and characteristics of Airplane Headache in children affected by primary headaches. ⋯ Our study shows that Airplane Headache is not a rare disorder in children affected by primary headaches and highlights that its features in children are peculiar and differ from those described in adults. In children Airplane Headache prevails in females, is more often bilateral, has frequently accompanying symptoms and occurs at any time during the flight. Further studies are needed to confirm the actual frequency of Airplane Headache in the general pediatric population not selected from specialized Headache Centres, with and without other concomitant headache condition, and to better clarify the clinical characteristics, pathophysiology and potential therapies.
