Primitive neuroectodermal tumors are fairly rare in uterus. A case of uterine body primitive neuroectodermal tumor in a 32-year-old Iranian woman is presented. ⋯ The tumor was strongly positive for CD99, NSE, and chromogranin; No reaction was seen for CD10, CD45 and myogenin. To the best of our knowledge, this is the first report of an uterine body primitive neuroectodermal tumor and the second report of uterine primitive neuroectodermal tumor from Iran.

Celiac disease (CD) is an immune disorder that is associated with gluten sensitivity in people who are genetically predisposed. In celiac disease, food containing gluten mounts inflammatory response that results in villous atrophy in small bowel and increased permeability. This disorder is not only related to complications in the small bowel, but also has association with manifestations outside the GI tract. ⋯ PubMed, Medline, Google scholar, SID, and Magiran were searched for full text articles published between 1999 and 2014 in Persian and English. The associated keywords were used, and papers, which described particularly the impact of infectious agents on celiac disease, were selected. In this review, we have focused on the role of infectious agents and gut microbiota in the pathogenesis of celiac disease.

High blood pressure is the second most important risk factor of cardiovascular diseases (CVDs) in Iran. It is imperative to estimate the burden of CVDs that can be averted if high blood pressure is controlled at the population level. The aim of the current study was to estimate the avertable CVD mortality in the setting of Golestan Cohort Study (GCS). ⋯ A very large proportion of CVD deaths can be averted if blood pressure is controlled in Iran. Effective interventions in primary and secondary health care setting are mandatory to be implemented as early as possible.

Alveolar hydatid disease is a highly malignant form of echinococcosis caused by the larvae of the cestode echinococcus multilocularis. Alveolar hydatid disease always affects the liver and can metastasise to the lung and brain. ⋯ The patient, who was presented with hepatomegaly, jaundice, and an infiltrative solid tumor, diagnosed by ultrasound and computed tomography. In contrast to hydatid cyst caused by echinococcus granulosus, this is a rare disease in Iran.

MicroRNAs are involved in key cellular processes regulating, and their misregulation is linked to cancer. The miR-302-367 cluster is exclusively expressed in embryonic stem and carcinoma cells. This cluster also promotes cell reprogramming and stemness process. In contrast, miR-145 is mostly regarded as a tumor suppressor, where it regulates cellular functions such as cell division, differentiation, and apoptosis. By suppressing the main pluripotency factors (OCT4, SOX2, MYC and KLF4), miR-145 silences the self-renewal program in ESCs. Therefore, the main aim of this study is to find a potential link between the expression level of hsa-miR-302b and hsa-miR-145 with tumor vs. non-tumor as well as high-grade vs. low-grade states of the esophageal tissue samples. ⋯ Our data revealed a significant down-regulation of miR-145 in ESCC tissue samples. Based on our ROC curve analysis data (AUC = 0.74, p < 0.001) miR-145 could be regarded as a potential tumor marker for diagnosis of esophageal cancer.
