This case involves a 36 year old non-smoker who worked in a factory producing food flavourings for potato crisps. He developed exertional breathlessness associated with fixed airway obstruction shortly after an uncharacteristically high exposure to the food flavouring chemical diacetyl. Unfortunately, even though he was removed from further exposure to this agent, his symptoms and spirometry di...

The key to maximize the chances of surviving exertional heatstroke is rapidly decreasing the elevated core body temperature. Many methods exist to cool the body, but current evidence strongly supports the use of cold water. Preferably, the athlete should be immersed in cold water. If lack of equipment or staff prevents immersion, a continual dousing with cold water provides an effective cooling...

Though migraine and tension-type headache are common, some primary headache syndromes are relatively rare and poorly recognized in daily practice. Despite the diagnostic challenges, the short-lasting primary headaches are important to recognize because of their excellent but highly selective response to treatment. In 1997 Goadsby and Lipton documented a nosological analysis and definition of a ...

PURPOSE The purpose of this study was a) to compare the effect of three different warm-up protocols upon rowing performance and perception of dyspnea, and b) to identify the functional significance of a respiratory warm-up. METHODS A group of well-trained club rowers (N = 14) performed a 6-min all-out rowing simulation (Concept II). We examined differences in mean power output and dyspnea mea...

Seven patients who developed a similar headache syndrome are described. They first developed severe, exploding headaches while swimming, and subsequently experienced less severe headaches during physical exertion. They also developed headaches during sexual activity, which were similar to the previous headaches brought on by swimming. Majority of them were women in their thirties or forties. Th...

results our study comprised 739 subjects (367 athletes and 372 non-athletes). among athletic university students, 152 (41.2%) participants complained of headache. such a complaint was present in 217 (58.3%) non-athletic university students. this lower prevalence of headache in athletes was statistically significant (p value < 0.001). among ten different sports fields, the prevalence of headache...

A previously healthy 45-year-old male patient seen in the Chest Pain Clinic giving a classical history for angina having developed exertional central chest/left arm discomfort while training for a marathon. He had a past history of infrequent migraines but nil else of note. He had a family history of ischaemic heart disease in first degree relatives and was an ex-smoker, he was just on aspirin....

Twenty-one patients experienced headache related to sexual activity. Two varieties of headache could be distinguished from the clinical histories. The first, developing as sexual excitement mount, had the characteristics of muscle contraction headache. The second, severe, throbbing or 'explosive' in character, occurring at the time of orgasm, was presumably of vascular origin associated with a ...

Headache is a common symptom of both the acute and post-COVID-19 periods which often persists for long time. leading among all neurological manifestations COVID-19, it also can be severe deconditioning disorder in about one fifth patients. A new type headache may occur or an existing primary cephalal gia pattern worsen patient with COVID-19. During period infection, cephalgia most patients cons...
