A collision tumor is one where histology shows the presence of two distinct primaries involving the same organ without intermixture of individual cell types, ie, a side by side pattern. Here we present three rare cases of collision tumors involving the stomach and transverse colon. There were two cases of collision tumors involving the stomach, one of which was a combination of adenocarcinoma and low-grade non-Hodgkin’s (mucosa-associated lymphoid tissue) lymphoma, and the other showed the presence of non-Hodgkin’s lymphoma involving the entire stomach wall along with adenocarcinoma infiltrating the muscle layer. The third case comprised a mucinous adenocarcinoma and carcinoid tumor in the large gut.

Alterations in serum concentrations of several trace elements including copper, zinc, manganese, and the macroelement magnesium have been reported to occur in type-2 diabetes mellitus. This study is done to evaluate copper, zinc and magnesium status in diabetic and nondiabetic human subjects. In this comparative analysis, the serum concentration of copper, zinc and magnesium was estimated in 60 patients with type 2 diabetes mellitus without complication and 40 healthy non-diabetic subjects. The data was analyzed by students't' test and Pearson's correlation coefficient test.Mean serum concentration of copper was significantly elevated in diabetic patients compared to control subjects. Serum zinc levels were significantly low (p < 0.001) in diabetic subjects compared to controls . There were no significant differences in serum magnesium between groups. Fasting plasma glucose level has significant positive correlation with serum level of copper (r = 0.567; p < 0.001), while zinc has negative correlation (r = -0.311; p < 0.047), but there is no significant correlation of plasma glucose level with serum magnesium level. Diabetic patients have significantly lower mean serum zinc levels and significantly higher serum copper concentration compared with healthy controls respectively. Along with antidiabetic therapy, supplementation of zinc and magnesium and chelation of copper can reduce complications due to diabetes mellitus.

Methods :The present study reviews a total 48 women with single pregnancy. These participants were categorized into control (n = 40), mild preeclampsia(n = 38) and severe preeclampsia (n = 10). The three study groups were statistically similar in aspects of maternal and gestational age and body mass index.

Multiple myeloma (MM) is a clonal proliferation of plasma cells with multiple osteolytic lesions. Multiple myeloma in the thorax is relatively uncommon. Hereby, we present 2 cases of multiple myeloma involving the thorax (1) in a 55 years old nonsmoker, female (2) and in a 45-years-old, smoker, male.
