Primary hydatid cyst of the fallopian tube: A case report.

Background: Human hydatid disease is caused by echinococcus granulosus and has a global distribution. It mainly affects the liver, but can involve other organs. In this paper, we present a case of a primary hydatid cyst of the fallopian tube.

An increased lung cancer risk associated with codon 72 polymorphism in the TP53 gene and human papillomavirus infection in Mazandaran province, Iran.

The TP53 gene has a polymorphism in exon 4 at codon 72 that presents the arginine or proline genotype. The association of TP53 codon 72 polymorphism with lung cancer risk has been studied by several groups, although with inconsistent results. Our previous study showed that the human papillomavirus (HPV) infection is associated with the development of lung cancer in Mazandaran, north part of Iran (cases=25.

Relationship between lung cancer and human papillomavirus in north of Iran, Mazandaran province.

Lung cancer is a major health problem and the leading cause of cancer deaths in the world. The pathogenesis of lung cancer is complex, and is believed to be due to the interaction between environmental and genetic factors. Various evidences show that HPV might be involved in bronchial carcinogenesis.
