The presence of cranial autonomic symptoms in migraine is well known and thought to represent activation of the trigeminal parasympathetic reflex pathway similar to trigeminal autonomic cephalalgias. However, studies regarding the prevalence of these symptoms are few. The characteristics of migraineurs with cranial autonomic symptoms and the association of cranial autonomic symptoms with laterality of headache have never been studied in a clinic population. Seventy-eight consecutive subjects with migraine were recruited from the Headache Clinic of the Department of Psychiatry after exclusion of subjects with secondary headache. Their demographic data and detailed history of headache were noted and leading questions were asked regarding cranial autonomic symptoms. chi(2) test and Fisher's exact test was used for categorical variables, whereas an independent sample t-test was applied on numerical data. Spearman's correlation was used for correlational analysis of categorical variables. Female subjects (78.2%) outnumbered males and the average duration of illness in the whole sample was 3.81 years. Migraine without aura (53.8%) was the commonest diagnosis, followed by migraine with aura (24.4%). Cranial autonomic symptoms were present in 73.1% of subjects and, commonly, they were ipsilateral to headache. Moreover, strictly unilateral cranial autonomic symptoms were reported by only 32% of patients. The anatomical side of headache did not affect the presence of autonomic symptoms. Those with or without autonomic symptoms did not differ with respect to gender, diagnosis, laterality of headache or associated symptoms except phonophobia, which was more common in subjects with autonomic symptoms (P = 0.05). Those with autonomic symptoms had longer duration of illness (P = 0.03) and longer headache episodes (P = 0.04). In addition, sleep was ineffective in relieving their headache (P = 0.02). Cranial autonomic symptoms are frequent in migraineurs and are common in subjects with long duration of illness and longer headache episodes. Clinical evidence in the present study suggests that subjects with cranial autonomic symptoms have a hyperactive efferent arm of trigeminal autonomic reflex. The connections of trigeminal nucleus with the locus coeruleus and dorsal raphe nucleus may account for the observed phenotypic differences between the two groups. Further research, however, is required to elucidate the underlying neural mechanisms of cranial autonomic symptoms in migraine.

In view of the substantial burden on family caregivers coupled with lack of adequate number of cancer hospitals, there is a public-health imperative to recognize this important group. All levels of health-staff in cancer hospitals in developing countries should be sensitized to the various burdens faced by family caregivers.

Background Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. Methods We pooled 2416 population-based studies with measurements of height and weight on 128•9 million participants aged 5 years and older, including 31•5 million aged 5-19 years. We used a Bayesian hierarchical model to estimate trends from 1975 to 2016 in 200 countries for mean BMI and for prevalence of BMI in the following categories for children and adolescents aged 5-19 years: more than 2 SD below the median of the WHO growth reference for children and adolescents (referred to as moderate and severe underweight hereafter), 2 SD to more than 1 SD below the median (mild underweight), 1 SD below the median to 1 SD above the median (healthy weight), more than 1 SD to 2 SD above the median (overweight but not obese), and more than 2 SD above the median (obesity). Findings Regional change in age-standardised mean BMI in girls from 1975 to 2016 ranged from virtually no change (-0•01 kg/m² per decade; 95% credible interval-0•42 to 0•39, posterior probability [PP] of the observed decrease being a true decrease=0•5098) in eastern Europe to an increase of 1•00 kg/m² per decade (0•69-1•35, PP>0•9999) in central Latin America and an increase of 0•95 kg/m² per decade (0•64-1•25, PP>0•9999) in Polynesia and Micronesia. The range for boys was from a non-significant increase of 0•09 kg/m² per decade (-0•33 to 0•49, PP=0•6926) in eastern Europe to an increase of 0•77 kg/m² per decade (0•50-1•06, PP>0•9999) in Polynesia and Micronesia. Trends in mean BMI have recently flattened in northwestern Europe and the high-income English-speaking and Asia-Pacific regions for both sexes, southwestern Europe for boys, and central and Andean Latin America for girls. By contrast, the rise in BMI has accelerated in east and south Asia for both sexes, and southeast Asia for boys. Global age-standardised prevalence of obesity increased from 0•7% (0•4-1•2) in 1975 to 5•6% (4•8-6•5) in 2016 in girls, and from 0•9% (0•5-1•3) in 1975 to 7•8% (6•7-9•1) in 2016 in boys; the prevalence of moderate and severe underweight decreased from 9•2% (6•0-12•9) in 1975 to 8•4% (6•8-10•1) in 2016 in girls and from 14•8% (10•4-19•5) in 1975 to 12•4% (10•3-14•5) in 2016 in boys. Prevalence of moderate and severe underweight was highest in India, at 22•7% (16•7-29•6) among girls and 30•7% (23•5-38•0) among boys. Prevalence of obesity was more than 30% in girls in Nauru, the Cook Islands, and Palau; and boys in the Cook Islands, Nauru, Palau, Niue, and American Samoa in 2016. Prevalence of obesity was about 20% or more in several countries in Polynesia and Micronesia, the Middle East and north Africa, the Caribbean, and the USA. In 2016, 75 (44-117) million girls and 117 (70-178) million boys worldw...
