Aims. Acute cholecystitis is one of the most common emergencies of general surgery. Although there is an increase in the incidence of acute cholecystitis in the summer season when the temperature increases, its cause is not fully understood. The aim of this study is to determine the relationship between acute cholecystitis and temperature. Material and Methods: 271 patients admitted to the general surgery service in 2021 were included in this study. Patient data were obtained retrospectively from patient files and data from national centers were used for meteorological data. Conformity of continuous variables to normal distribution was evaluated using visual and analytical methods. Results: According to the percentage distribution of cases, acute cholecystitis was most common in summer and least in winter. A very strong positive correlation was found between monthly mean temperature values and monthly incidence of acute cholecystitis (correlation coefficient: r= 0.759 and p=0.004). Conclusions: The incidence of acute cholecystitis also increases with increasing ambient temperature, and this is important in terms of planning health services.
Purpose: The De Ritis ratio (Aspartat transaminase/alanine transaminase) is a critical prognostic factor for some kinds of malignant tumors. Nevertheless, the De Ritis ratio’s prognostic value in preoperative colon cancer staging is unclear. The purpose of this research was to determine the De Ritis ratio in colon cancer and to determine its prognostic significance for colon cancer. Materials and Methods: The clinicopathological data of 271 individuals with malign colon cancer were analyzed retrospectively, from January 2010 to January 2018 at a single center. The relationship between the De Ritis coefficient and clinicopathological findings in patients were evaluated before treatment. To compare groups, the Mann-Whitney U test and the Kruskal Wallis test were performed. Results: The results indicated that there were no statistically significant differences between the groups, in terms of pre-treatment De Ritis ratio assessment as a staging, localization, tumor diameter, lymph node metastasis, age and overall survival. However, differences in T staging between groups of male participants were shown to be statistically significant. Conclusions: The De Ritis ratio evaluated before to treatment was not an independent variable a prognostic factor in the diagnosis and staging of colon cancer. However, future study may demonstrate the significance of the De Ritis ratio with more participants.
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.
