The aim of the paper is to give a review of jet-lag (Time Zone Change Syndrome) with regard to aetiology, symptomatology and pathophysiology. Furthermore we give recommendations on treatment of jet-lag. ⋯ Both phototherapy and melatonin have the capability to accelerate reentrainment of the circadian rhythm after flights across multiple time zones, thereby reducing jet-lag. We stress the importance of correct timing of phototherapy and use of melatonin and suggest that the traveller adapts to the "social" rhythm at the flight destination as well.

We report a case of a 5-week-old infant admitted with respiratory arrest. He had been fed with honey for two weeks. Infant botulism was suspected and confirmed by the finding of Clostridium botulinum toxin in the serum and faeces, and in the honey. The infant needed 7.5 months of ventilatory support.

Case Reports[Respiratory insufficiency caused by dapsone-induced methemoglobinemia].
We present a case of pneumonia and dapsone-induced methaemoglobinaemia. Methaemoglobinaemia leads to impaired delivery of oxygen to tissue. In our patient we observed that methaemoglobin interferes with the accuracy of pulse oximeter data. The patient was successfully treated with methylene blue, which converts methaemoglobin back to haemoglobin.
