Objective To investigate the etiological and clinical characteristics of the outbreak of hand-foot-mouth disease (HFMD) in Chengdu in 2008. Methods A retrospective analysis was conducted to investigate 482 children with hand-foot-mouth disease in Chengdu from January to December 2008 in terms of epidemiology and clinical characteristics. Results Among the 482 children, 76.14% of the cases were infants, and male children numbered more than female ones. The proportion in the urban area was higher than that in the rural area. May to July was the peak epidemic period. Skin rash and fever were major clinical manifestations. Three cases were diagnosed as viral encephalitis. Conclusion The incidence of hand-foot-mouth disease is related to age and season. Effective prevention measures and isolated treatment are critical for prevention and therapy.
Objective To investigate the incidence of urolithiasis in the children who ingested milk powder tainted with melamine in the Chengdu area. Methods A total of 5 795 infants were screened for urolithiasis by ultrasound examination from September 17, 2008 to December 9, 2008. The data were analyzed using SPSS 13.0 software.Results Twenty-four children were diagnosed with urolithiasis with an incidence of 0.41%, including 12 males and 12 females. The mean age of those children with urolithiasis was 2.35±1.68 years old. No significant difference was shown in the incidence of urolithiasis between males and females (Pgt;0.05). The incidence of urolithiasis in the infants aged 0-3 was significantly higher than that in the children who were more than 3 years old (Plt;0.05). Conclusion The incidence of urolithiasis in the infants aged 0-3 in Chengdu and the surrounding areas is relatively high. Further data should be collected during the follow-up of these cases.
