However, there have been very few studies addressing this issue in Iran. This study was conducted to determine the prevalence of intestinal parasitic infections in renal transplant recipients in Iran. Stool specimens from renal transplant recipients and control groups were obtained between June 2006 and January 2007. The samples screened for intestinal parasitic infections using direct smear, formalin-ether sedimentation, Sheather's flotation and modified Ziehl-Neelsen staining methods. Out of 150 renal transplant recipients, 33.3% (50), and out of 225 control group, 20% (45) were infected with one or more type of intestinal parasites. The parasites detected among patients included Entamoeba coli (10.6%), Endolimax nana (8.7%), Giardia lamblia (7.4%), Blastocystis spp. (4.7%), Iodamoeba butschlii (0.7%), Chilomastix mesnili (0.7%) and Ascaris lumbricoides (0.7%). Multiple infections were more common among renal transplant recipients group (p < 0.05). This study highlights the importance of testing for intestinal parasites among Iranian renal transplant recipients. Routine examinations of stool samples for parasites would significantly benefit the renal transplant recipients by contributing to reduce severe infections.
Background and Objectives:Breast cancer is a major threat to women's health. Evaluation of the changes in trend of the incidence rate provides valuable information for the assessment and planning of development indicators of each country. The aim of the present study was to apply the JoinPoint regression model for determining changes in the trend of the breast cancer incidence rate in Isfahan.Materials and Methods:In this cross-sectional study, 3640 women with breast cancer referring to oncology and radiotherapy departments of Seyed-al-Shohada and Milad cancer treatment centers of Isfahan during 2001–2010 were studied and sampling was not done. Joinpoint regression model was used to investigate the pattern of breast cancer incidence rate. Response and independent variables were the natural logarithm of the age-standardized incidence rates and year of diagnosis of breast cancer, respectively, in which various levels of cancer tumor characteristics (P < 0.05) were analyzed.Results:The incidence rates increased annually in the age groups of 40–44 years (6.2%), 45–49 years (5.3%), and 55–59 years (5.3%). The trend of incidence rates in women with tumor size ≤2 cm (18.2%), well (moderately) differentiated tumor grade [8% (10.2%)], positive estrogen (progesterone) hormone receptor status [10.5% (6.9%)], and the proportion of positive lymph node to surgery node ≤25% (nonsignificant) was upward.Conclusion:The trend of incidence rates with tumor size ≤2 cm, well-differentiated tumor grade, moderately differentiated tumor grade, and positive estrogen and progesterone hormone receptors was upward. The pattern of breast cancer can help in cancer prevention and prognosis, and in selecting the best type of surgery.
Background:Prognostic tools are widely used in the practice of Oncology and have been developed to help stratify patients into specific risk-related grouping. We sought to apply of two such tools used for patients with early-stage breast cancer and to correlate them with actual outcomes.Methods:A retrospective study was designed to include early-stage breast cancer cases seen from 1994 to 2014 at the Seyedoshohada Hospital in Isfahan, Iran. Information was derived from the patients’ records, and indices were derived from prognostic tools. Information was analyzed using descriptive statistics and one sample t-test.Results:In 233 patients, the difference between the predicted overall survival (OS) by the Adjuvant Online (AO) prognosis tools (69.28) and the observed OS (71.2) was not statistically significant (P = 0.52), and the AO prognosis tools had predicted the patients’ OS correctly. In the Nottingham prognosis index (NPI), this difference in all groups except the very poor prognosis group was not statistically significant.Conclusions:Adjuvant Online prognosis tools were capable of predicting the 10-year OS rate although not in all of the subgroups. The NPI was capable of distinguishing good, moderate, and poor survival rates, but this ability was not visible in more specific groups with moderate and poor prognosis.
The objective of this study is to evaluate tonsil odor as a contributor to halitosis and to study the reduction of oral malodor by mouth rinsing, without tonsil treatment. In 48 halitosis patients, tonsil odor and oral malodor were assessed through the 0-5 scale. In tonsil odor assessment, a dental burnisher was inserted into the tonsilar crypts and was sniffed by an odor judge. Oral malodor was analyzed through a plastic straw using the same scale by the same judge. The concentrations of H(2)S, CH(3)SH and (CH(3))(2)S were measured by a portable gas chromatograph (GC) (OralChroma) in ppb. After the baseline evaluations the subjects were instructed to scrape the surface of the tongue daily and rinse with a zinc-containing mouthwash twice daily for 1 month. After this period the same evaluations were repeated. Data were analyzed by SPSS software, paired t-test and Pearson correlation. Before mouthwash test: mean values of oral malodor scores and tonsil odor scores were 4.2 and 3.7, respectively. Pearson correlation analysis showed that oral malodor scores and tonsil odor scores had a significant correlation (p = 0.025). Oral malodor scores were correlated with the concentrations of H(2)S (p = 0.0001), CH(3)SH (p = 0.041) but not with (CH(3))(2)S concentration. After mouthwash test: mean values of oral malodor scores and tonsil odor scores were 2.2 and 3.0, respectively. Tonsil odor scores and oral malodor scores were not correlated. Also the paired t-test results showed that the effect of the mouthwash on the reduction of oral malodor and tonsil odor was not the same. Since oral malodor was successfully reduced while tonsil odor remained with a little reduction, it is concluded that tonsilar treatment such as tonsillectomy and laser cryptolysis might be considered only after the failure of mechanochemical therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
