Cluster headache (CH) is considered as a primary headache syndrome, thus neuroradiological investigations of the central nervous system should be normal in primary CH patients (1). However, symptomatic cluster-like headaches (CLH) have been reported in association with various disorders such as aneurysms, arteriovenous malformations, cervical trauma, medullary infarcts, inflammatory/infectious ...

A 15 year old patient with a 6 month history of cough headache was diagnosed as having a Chiari I malformation. The midsagittal T1 weighted MRI shows the tonsillar ectopia (figure A). A flow sensitive MRI, cardiac triggered gradient echo T2* weighted sequence obtained at 200 ms from the R wave, showed absence of CSF flow through the foramen of Magendie (figure B). After craniovertebral decompre...

AIMS This study was undertaken to evaluate the epidemiological features and the prognostic implications of syncope in young athletes. METHODS AND RESULTS A cohort of 7568 young athletes (5132 males, 2436 females, aged 16.2 +/- 2.4) underwent a pre-participation evaluation. A syncopal spell in the last 5 years was reported by 474 athletes (6.2%). Syncope was unrelated with exercise in 411 athl...

tracheobronchopathia osteochondroplastica (to) is a rare disorder of large airways with unknown etiology which is characterized by cartilaginous and bony nodules lining the mucosa of the trachea and major bronchi. generally, it is benign and asymptomatic, but it may present with cough, exertional dyspnea and wheezing. it could therefore be mistaken with asthma and chronic obstructive pulmonary ...

PURPOSE A recent study demonstrated that exertional desaturation is a predictor of rapid decline in lung function in patients with chronic obstructive pulmonary disease (COPD); however, the study was limited by its method used to detect exertional desaturation. The main purpose of this study was to explore whether exertional desaturation assessed using nadir oxygen saturation (SpO₂) during the ...

background: research into the role of neuroimaging in primary headaches such as tension type headache (tth) is ongoing. in the present study, we aim to evaluate the ability of neuroimaging to detect potential abnormalities in patients with new onset tth and normal neurological exam. materials and methods: in a prospective study, 294 cases of new onset tth with normal neurological exam, that had...

Objective Peripheral arterial disease (PAD) is a common complication of diabetes, associated with impairment in angiogenesis. Angiogenesis is regulated by angiogenic growth factors such as angiopoietin 1 (Ang-1), Ang-2, and vascular endothelial growth factor (VEGF). We studied the association between angiogenic growth factors versus PAD and exertional leg symptoms in diabetes patients in Ghana....

BACKGROUND Exertional heat stroke is a fatal condition and remains a health problem. This paper evaluates the publication trend regarding exertional heat stroke research between 1996 and 2015 using a bibliometric method. METHOD Articles regarding exertional heat stroke research published between 1996 and December 2015 were searched for in the SCI-EXPANDED database of Web of Science. The searc...
