Introduction: Adenosarcoma is a rare uterine tumor composed of benign epithelial and malignant stromal elements. In 20% of cases stroma contains heterologous elements (usually from stratified muscle type). Association between Tamoxifen usage (exogenous strogen) or ovarian thecoma (endogenous strogen) and occurance of this tumor has been reported. This is a case report of a uterine Adenosarcoma. Case: The patient was a 45 years old woman with history of 16 years OCP use who was admitted with a uterine mass and undergone total hysterectomy. Microscopic assessment of slides, stained by H&A, was indicator of Adenosarcoma with cartilage heterologous elements. Conclusion: Uterine Adenosarcoma is a rare tumor. Although there is a few reports of cartilage heterologous elements in uterine Adenosarcoma, this case had multiple cartilage points in stroma. Also in this case, the coexistance of this tumor with long- term OCP use was considerable.

Background: This investigation was designed to determine the effects of a selective A1-AR antagonist (DPCPX) on renal hemodynamic and excretory dysfunctions induced during the early hours of ischemia/reperfusion (I/R). Materials and Methods: In this experimental research, rats were anaesthetized by sodium pentobarbital, and their renal arteries were, then, occluded for 30 min, four hours after the reperfusion period. There was a clearance period during the last one hour of reperfusion period throughout which urine was collected under 30-mm of paraffin, and arterial blood samples were taken during its beginning and end. Animals were divided into four groups DPCPX (2 mg/kg) or normal saline were injected 30 min before renal ischemia to the two groups of I/R+DPCPX and I/R, respectively, and to DPCPX and Sham groups which were subjected to surgery without clamping of renal arteries, respectively. Results: I/R resulted in elevations of plasma osmolality, plasma concentrations of Na, K, creatinine, and urea, fractional excretions of Na, K, and bicarbonate, absolute bicarbonate excretion, and urinary pH, but it induced reductions in arterial bicarbonate concentration, pH and Pco2, creatinine clearance, absolute excretions of Na and urea, free-water re-absorption, and urinary osmolality in the I/R group in comparison to the Sham group. Comparison between I/R+DPCPX and I/R groups showed that applying DPCPX could improve I/R-induced alterations in most of these parameters. Conclusion: Activation of A1-AR during the early hours of reperfusion following renal ischemia definitely contributes to the development of disorders in hemodynamics, tubular Na re-absorption, as well as excretions of K, urea, and acid-base.

Background: Transient hip tenosynovitis is one of the common causes of pain and limping in children and includes 0.4% to 0.9% of admissions in emergency wards. The aim of this study is to evaluate this disease in terms of clinical presentations, age and sex distribution, and six-month recurrence. Materials and Methods: In this cross-sectional study, 51 children with diagnosis of transient hip tenosynovitis were investigated. Inclusion criteria were physician's clinical suspicion of acute tenosynovitis according to clinical presentations, physical exam, and age range of 3 to 8 years. Results: Among the 51 children with tenosynovitis, 34 patients were male with age of 61.70±19.1 months and 17 patients were female with mean age of 48.35±20.49 months that presented a significant statistical difference (p=0.026). The most common complaint was hip pain and the most commonly involved joint was the hip. Also, most of the patients had the history of viral diseases. Conclusion: Transient hip tenosynovitis is more common in boys. The right hip is the most involved joint and the majority of patients have the history of recent viral diseases.

Background: Nitric oxide is synthesized in endothelial cells by eNOS and acts as a pleiotropic regulator involved in carcinogenesis. Most gastric cancers develop from stomach epithelial cells therefore, NO may play a role in their development. Polymorphisms of eNOS have been shown to be associated with cancer susceptibility. In the present study, we investigated the association of the eNOS genotypes with gastric cancer risk in Guilan Population.

Materials and Methods: In this case-control study, we analyzed the Glu298Asp polymorphism of eNOS in 87 patients with gastric cancer and 90 healthy controls. The genotyping of eNOS polymorphism was performed using polymerase chain reaction–restriction fragment length polymorphism assays. All statistical analyses were conducted by the MedCalc statistical software.

Results: No association between the eNOS genotypes and gastric cancer risk was found. Among the 87 patients, 45 had Glu/Glu, 38 were Glu/Asp, and 4 were Asp/Asp. In the control group, 44 had Glu/Glu, 40 were Glu/Asp, and 6 were Asp/Asp. We found no significant differences in allele and genotype frequencies between control and patient specimens.

Conclusion: We found that there was no association between this polymorphism and gastric cancer risk. Results suggest that eNOS polymorphism may play a role in inhibition of gastric cancer. However, larger population-based studies are needed for clarifying the role of eNOS polymorphism in gastric cancer.
