Epidemiology and histopathology of breast cancer in iran versus other middle eastern countries

Background: Breast cancer is the most prevalent cancer among females worldwide. This study compares the results of the most cited published Iranian studies and studies from other Middle East countries on breast cancer with data from the Ministry of Health and Medical Education and approximately 2000 cases from the Cancer Research Center of Shahid Beheshti Medical University of Iran. Methods: Data from the Cancer Registry System of the Ministry of Health and Medical Education and the Cancer Research Center were obtained in addition to data from other published Iranian articles to increase the accuracy of incidence, prevalence, disease burden, risk factors, clinical staging, clinical pathology, biological markers, clinical subtypes, and survival rate of breast cancer in the last decade and compare the epidemiological data with other areas of the world. Results: Overall, breast cancer was the most common cancer in Iran. The age-standardized rate for breast cancer was 33.21 per 100,000 according to the latest national databases. The mortality rate for breast cancer has not changed in the past 30 years in Iran. The age-standardized rate for mortality was 14.2 per 100,000 with a mean age of 49.84 years. The most common cancer in Iran is invasive ductal carcinoma. In our last review, 65.5-70.5 of cases were in the early stages (1 and 2) and less than 30 were in the advanced stages. The five-year overall survival rate was estimated at 72 in women and 60 in men. The stage and number of positive lymph nodes significantly affected the survival rate. In the Gulf Cooperation Council, ASR of the Kingdom of Saudi Arabia was (12.9), Bahrain (46.4), Kuwait (44.3), Qatar (35.5), United Arab Emirates (19.2), and Oman (14.4) per 100,000. Conclusion: Our study shows that epidemiology and histopathology of cancer is different with other neighborhood countries and is multi-dimension and needs multi-center involvement from government authorities, clinicians and scientists. © 2018, Shiraz University of Medical Sciences.

Traumatic Pulmonary Pneumatoceles (Pseudocyst)

Introduction: Traumatic pulmonary parenchymal cavitary lesions (TPPCs) are pulmonary pseudocysts raiding secondary to lung contusion. Method: To provide an overview of the etiology, presentation, diagnosis and treatment of TPPCs, and to discuss this in the context of a cohort of 12 retrospectively reviewed patients with TPPCs presenting to Sahlgrenska University Hospital, Gothenburg, Sweden, from January 2014 to December 2016. Between January 2014 and December 2016, a total of twelve trauma patients presented to Sahlgrenska University Hospital with TPPC following blunt trauma. Results: TPPCs are of limited clinical consequence. Inexperienced clinicians may treat these inappropriately. A Computed Tomography (CT) scan is the investigation of choice. Treatment is symptomatic. Intervention is indicated only in case of complications

Parasites of non-native freshwater fishes introduced into england and wales suggest enemy release and parasite acquisition

When non-native species are introduced into a new range, their parasites can also be introduced, with these potentially spilling-over into native hosts. However, in general, evidence suggests that a high proportion of their native parasites are lost during introduction and infections by some new parasites from the native range might occur, potentially resulting in parasite spill-back to native species. These processes were investigated here using parasite surveys and literature review on seven non-native freshwater fishes introduced into England and Wales. Comparison of the mean numbers of parasite species and genera per population for each fish species England andWaleswith their native ranges revealed\9 % of the native parasite fauna were present in their populations in England and Wales. There was no evidence suggesting these introduced parasites had spilled over into sympatric native fishes. The non-native fishes did acquire parasites following their introduction, providing potential for parasite spill-back to sympatric fishes, and resulted in non-significant differences in overall mean numbers of parasites per populations between the two ranges. Through this acquisition, the non-native fishes also had mean numbers of parasite species and genera per population that were not significantly different to sympatric native fishes. Thus, the non-native fishes in England and Wales showed evidence of enemy release, acquired new parasites following introduction providing potential for spill-back, but showed no evidence of parasite spill-over
