ABSTRACT
Background: Lung cancer (LC) is a global public health priority. In this study, the epidemiology and current trends of primary LCs were investigated in northeast of Iran. Methods: Demographic and pathologic records of primary LCs during 1985-2012 in Mashhad (capital of northeast of Iran) were reviewed. Data were obtained from archives of the largest referral oncologic hospital and the only private outpatient radiation-oncologic clinic in the region. To investigate trends, study duration was classified into 3 periods: 1985-1995, 1995-2005, and 2005-2012. Patients were placed in one of these 3 groups, based on the date of their pathologic diagnosis. Data were analyzed by SPSS 16 software. T test, chi-squared, and ANOVA tests were used for data analysis, and statistical significant level was set at < 0.05. Results: Among 939 cases with pathologic diagnosis of primary LC, male-to-female ratio was 2.36. Mean±SD age at diagnosis was 61.47±12.01 years in males and 58.45±12.75 in females (p=0.001). Squamous cell carcinoma (SCC) was the most frequent pathologic subtype. Mean age at diagnosis and rate of smokers were unchanged during the study (p= 0.978 and 0.153, respectively). Relative frequency of leading pathologic subtypes changed in 3 intervals (p<0.001): it was increasing in adenocarcinoma and large cell carcinoma and decreasing in SCC and small cell lung cancer (SCLC). There were statistically significant differences in the mean age at diagnosis (p<0.001), rate of smokers (p<0.001), and male-to-female ratio (p=0.011) between leading pathologic subtypes. Conclusion: Similar to universal picture, rate of adenocarcinoma in northeast of Iran was rising during recent decades, especially among younger patients, women, and nonsmokers. These trends are indicative of changes in exposures and smoking habits and reveal the need for regional studies in these contexts.
ABSTRACT
Given the importance of heavy menstrual bleeding (HMB), we investigated the effect of plantain syrup on HMB. This randomized clinical trial was performed on 68 women with HMB who were referred to the traditional medicine clinics of Mashhad University of Medical Sciences. The intervention group received placebo capsule and plantain syrup, whereas the control group received mefenamic acid capsule and placebo syrup in the first 5 days of menstruation for three menstruation cycles. Patients were asked to complete pictorial blood assessment chart one cycle before the intervention and three intervention cycles. Hemoglobin was measured at the beginning and at the end of the study. The results showed that the bleeding duration and severity diminished in both groups. No significant difference was observed between two groups in severity of bleeding after intervention (Cohen's d = .24), but duration of bleeding in mefenamic acid group was reduced significantly in comparison with plantain group (Cohen's d = .57). Although mean hemoglobin alterations in mefenamic acid group had a significant difference before and after the intervention, there was no significant difference between the two groups in mean hemoglobin alterations postintervention. Plantain syrup could be suggested as a complementary treatment for HMB, but further studies are required.
