Background: Kawasaki syndrome is considered as the leading cause of cardiovascular disease among children. The aim of the present study was to determine the prevalence of cardiovascular complications among Kawasaki patients of Yazd province.

Materials and Methods: In this cross-sectional study, the medical documents of all patients (no = 48) referring to Yazd hospitals with a diagnosis of Kawasaki syndrome (during the march 1996 – march 2006) were reviewed and the related demographic, clinical, paraclinical, echocardiographical and therapeutical data were collected through the questionnaire. The obtained data were analyzed using the Chi–square and t-test statistical tools.

Results: Nineteen (39.5%) out of the 48 Kawasaki diagnosed patients had cardiovascular affliction (male 63.2%). All Cardiovascular afflicted patients had coronary aneurysm and a history of more than 5 days fever, whereas this was the case in 89.7% of non- cardiovascular afflicted . ESR mean in cardiovascular afflicted patients was higher than that in the non–afflicted ones (p = 0.04) .

Conclusion: The high affliction of cardiovascular and coronary aneurysm among the Yazd Kawasaki patients is considerable. ESR levels may be helpful in diagnosing the high risk patients for Kawasaki syndrome.

Background: The presence of heavy metals in higher concentrations and more than their permissible levels in our environment is of great concern because of their toxicity. These metals enter the environment through different ways (e.g. industrial activities).

Materials and Methods: This study has quantified the contaminants in fish muscular tissue samples and followed the guidelines of U.S. Environmental Protection Agency (EPA) to estimate their hazard indices. The samples taken from Abramis brama were collected from Anzali Lagoon. Spectroscopic techniques were used for determination of Cd (Cadmium), Cr (Chromium) in fish muscular tissue.

Results: The concentration of Cr (0.88±0.09 µg/g dry wight) was higher compared with Cd (0.19±0.02 µg/g dry wight) the concentrations of other metals were not higher than the maximum permissible level. The suggested hazard index<1 was acceptable for dairy intake of human.

Conclusion: Although the heavy metals analyzed in Abramis brama from Anzali did not pose any immediate health risk to humans but due to the bioaccumulation and magnification of these heavy metals in humans, it is essential to reach safeguard levels of the metals in the environment.
