1. Coronavirus (CoV)-HKU1 accounts for 2.4% of community-acquired pneumonia. 2. Clinical features alone cannot differentiate this entity from other community-acquired pneumonia. 3. Further studies are needed to understand the significance of CoV-HKU1 in upper respiratory tract infection and its potential to cause outbreaks of acute viral respiratory illnesses.

A patient who was given metoclopramide for vomiting and diarrhoea developed circulatory collapse with his blood pressure dropping to 50/20 mm Hg. A gastrinoma was diagnosed histologically. The extent of the tumour was defined by octreotide scanning and magnetic resonance imaging. ⋯ Follow-up octreotide scanning did not show any residual tumour. Possible causes for the circulatory collapse are discussed. Our case is probably the first patient with gastrinoma to develop circulatory collapse after being given metoclopramide.

To investigate the association between obesity and airway inflammation and spirometric parameters in local children. ⋯ Increased airway inflammation as revealed by exhaled nitric oxide concentration was found in obese non-asthmatic children. Weight-for-height z-score as an indicator of childhood obesity correlated with exhaled nitric oxide concentration and spirometric parameters in children without asthma. Nonetheless, concomitant obesity does not influence exhaled nitric oxide concentration in asthmatic children. Further studies are needed to identify the pathophysiologic mechanisms for such associations.
