Headache is a predominant disorder in general population and is classified into primary and secondary forms by the International Headache Society. Fasting headache is currently classified in Group 10 of ICHD-III as “Headache attributed to disorders of homeostasis”. In spite of continuing research, there is still indistinctness regarding the exact cause of fasting headache. Hypoglycaemia, previous history of headache, stress, caffeine withdrawal, lack of sleep and female gender have been speculated as causative factors. Our rationale for this study is to find out what percentage of the population experiences fasting headache and to find out any link between the occurrence …

Polio Travel Restrictions: A Sledgehammer To Crack A Nut?, Rashid Jooma
Polio Travel Restrictions: A Sledgehammer To Crack A Nut?, Rashid Jooma
Section of Neurosurgery
Imposition by WHO of mandatory vaccination for international travelers from Pakistan has caused confusion and panic amongst travelers besides the adverse effect on the country's image from the widely reported statement. It is felt that the announced measure is not primarily supported by science but is rather a response to disillusionment in the donors about the repeatedly missed eradication targets set by WHO. In the past few years, exportation of poliovirus from Pakistan has caused outbreaks in China, Iraq and Syria besides the ongoing two way transmission with Afghanistan, but the carriers in these spreads are mainly land route travelers. …
