Sleep deprivation was common in the studied cohort and it was associated with a decrease in Mathematics performance. Excessive sleepiness on rising and sleepiness during third and fourth lessons were associated with poorer grades in Mathematics and English. Excessive daytime sleepiness was reported in 25% of students. Bruxism and snoring were associated with excessive daytime sleepiness.

Around 40.6% of habitually snoring children continued to snore habitually as adolescents in the current study, while 9.2% of the initial non-habitual snorers became habitual snorers. Male gender and higher BMI were significant risk factors for both persistent and incident habitual snoring.

A 33-year-old Indian male was hospitalised for a 3-day history of headache and left lower limb weakness in December 2014. He had experienced no fever or seizures. He had visited New Delhi, India, the year before. Physical examination revealed the patient to be fully conscious with left lower limb monoparesis. There was no sensory deficit. Computed tomography (CT) revealed a superior parietal intraaxial lesion with a calcified focus (Fig 1a). Magnetic resonance imaging (MRI) delineated a 2 x 1.5 x 1.5 cm circumscribed hypointense cystic lesion with a contrast-enhancing wall and an eccentric intracystic signal with perilesional oedema (Figs 1b to 1d). Differential diagnoses included neurocysticercosis, brain abscess, brain metastasis, and malignant glioma. Craniotomy for excision was performed PICTORIAL MEDICINE
