Objective: To describe the clinical and histopathological characteristics of malignant colon tumors acording to their location.
Material And Methods: Descriptive, retrospective study with 94 patients diagnosed with colon cancer.

Article Synopsis
- Cataract surgery with an intraocular lens implant is the most common surgical procedure globally, and the success relies heavily on accurately calculating the lens's dioptric power.
- This study aims to compare the dioptric power calculation in cataract patients with and without pupil dilation by analyzing various factors like age, gender, and biometry.
- The results showed no significant differences in dioptric power calculations between the two groups, indicating that pupil dilation does not significantly impact the accuracy of these calculations.
Objective: To determine the prevalence of pulmonary thromboembolism (PET) and identify it's risk factors in patients operated on a scheduled basis, in the general surgery service from the High Specialty Medical Unit Hospital de Especialidades de Puebla, of the Mexican Social Security Institute.
Method: Descriptive, retrospective and cross sectional study of 52 patients' records with PET and pulmonary angiotomography whose indication was respiratory distress; from 2612 operated patients from November 2015 to March 2018, the sampling was not probabilistic. The statistics was descriptive, with measures of central tendency and dispersion.
