Several lines of evidence suggest that, of the three main races of Singapore, peptic ulcers are more common among the Chinese and Indians when compared to the Malays. These include studies on hospital series of patients with or without appropriate control groups, studies on the incidence of surgery for perforated ulcer as well as mortality statistics. ⋯ The incidence of perforated ulcer in Singapore is increasing while ulcer mortality is declining. This is similar to the situation in Hong Kong but different from that in the western countries.

Case Reports
Nasal positive pressure ventilation in the treatment of chronic hypercapnic respiratory failure: a case report.
This paper describes the use of a nasal mask to deliver intermittent positive pressure ventilation to treat chronic respiratory failure in one patient with severe kyphoscoliosis. After two months of overnight nasal ventilation at home the patient achieved normal blood gases, showed improved inspiratory muscle strength, effort tolerance and was able to return to work. Intermittent nasal ventilation is a safe and effective ventilatory support modality for some patients with hypercapnic respiratory failure.
