A GROWING number of child abuse cases appear to centre on districts where living conditions are poor, a Kwong Wah Hospital paediatrician said yesterday. Consultant paediatrician Dr Robert Yuen Kar-ngai said the number of cases of shaken baby syndrome, which leaves youngsters physically disabled or permanently retarded, had increased in recent years. Doctors were concerned at the frequency with which children were being brought to hospitals with symptoms of the condition. 'My impression is that this shaken baby syndrome, which is usually done by parents or carers, is increasing,' Dr Yuen said. 'I have been told that child abuse might be more common in certain areas of Hong Kong such as Kwung Tong and the new urban areas, and this could be down to poor living conditions.' Dr Yuen was speaking after it was revealed on Friday that 10 such cases had been discovered at Tuen Mun Hospital since 1994. Four of the victims had died and the remainder suffered severe injuries. Meanwhile, consultant paediatrician Dr Daniel Ng Kwok-keung said a new sleep laboratory would be set up early next year to diagnose breathing disorders in children who snore. Dr Ng, also from Kwong Wah Hospital, said children's breathing patterns would be monitored as they slept. Studies indicated that children who snored every night could be exhibiting symptoms of a severe breathing disorder.
