RESUMEN
We reported a 16-year-old boy who developed Henoch-Schönlein purpura (HSP) 15 days after receiving a seasonal influenza vaccine. His symptoms improved temporally with treatment but he developed HSP nephritis (HSPN) that relapsed multiple times over the following three years. This case of Henoch-Schönlein purpura may have been due to the seasonal influenza vaccine. The mechanism for this association is unclear. Practitioners should be aware of this possible complication.

BACKGROUND: China has become the world's largest producer and consumer of tobacco and lung cancer is China's leading cause of cancer deaths. The large majority of Chinese smokers are men. Tobacco consumption is of particular concern among China's internal floating (or migrant) population, which has become a permanent feature of Chinese society, because this population is very large (over 100 million persons) and it has a high prevalence of smoking. Considering additionally that like the general population of China, the smoking prevalence rate of women from this group is quite low, we therefore aimed to explore smoking-related knowledge, attitudes and behaviours among male smokers in the floating population to help inform the development of effective smoking cessation interventions in this important target group in China. METHODS: We interviewed 39 floating population male smokers in six focus groups and performed a qualitative content analysis of the interviews. RESULTS: Most participants knew that smoking is risky to health but they knew little about why. Habit and social participation were key drivers of smoking. Smoking was regarded as a core component of their identity by the urban residents. Some participants had tried to stop smoking but none reported having ever been educated about smoking. CONCLUSIONS: Smoking cessation interventions for China's male floating population would need to incorporate comprehensive education and information about why smoking is dangerous and the benefits of stopping.

448 public health practitioners in the district were selected randomly from Dec. 2010 to Mar. 2011. Blood specimens were collected and tested for anti-T. gondii IgG by ELISA. The result showed that the positive rate was 10.3% (46/448). No significant difference was found between males and females, so as different cities of origin (P > 0.05). The positive rate was higher in > or = 30 age group (14.9%, 29/195) than that in < 30 age group (6.7%, 17/253)(P < 0.05), and the highest sero-prevalence was recorded in 30-39 age group (15.8%, 16/101). The positive rate was higher in subjects engaged in the food production and processing enterprises (12.6%, 36/286) than those in other industries (6.2%, 10/162) (P < 0.05).
