Background: Student absenteeism refers to the frequent absence from classes without any good reason and thought to be the primary concern in health profession education worldwide mainly in medical school. Methods and Material: This study is a cross sectional design conducted in 152 medical students of King Saud Bin Abdulaziz University for Health Sciences (KSAU-HS), Saudi Arabia. A self-reported questionnaire was used to determine absenteeism behavior, contributing factors of absenteeism, and level of satisfaction of medical students towards the medical program of the university. Adapted questionnaire from Timmins and Kaliszer (9) was also utilized to examine factors of stress among medical students. Descriptive statistics, linear correlation and Pearson correlational coefficient utilizing SPSS v22 for the analysis of data. Results: A total of 143 (92.76%) participated in the study. 104 or 72 % were male, and 28% were female with mean age of 22.5 (±2.02) and a mean GPA of 4.4 (±0.4). 77 (53.8%) of students were absent for 5 times or more in lectures/basic and clinical sciences sessions and clinical diagnostic sessions. These absences are mainly because of study (n=36, 25.2%) and course dissatisfaction (n=32, 22.4%). However, only 3 (2.1%) who had an absence for 5 times or more in Problem Based Learning (PBL) sessions. These absences in PBL sessions are mainly because of sleep (n=11, 7.7%) and family commitments (n=10, 7.0%). There is an inverse correlation between absenteeism and academic performance. Conclusion: Absenteeism has a negative impact on the academic performance of medical students.

Aim of the work: surgical site infections are the second most common cause of hospital acquired infections and happens in 10%-30% of all patients undertaking gastrointestinal surgery. They are more likely to be admitted in critical care unit and have five times higher mortality than those patients without surgical site infections. Prophylactic use of antimicrobials and other preparations before surgery have shown significant reduction in infectious complication. After surgery the treatment of postoperative bacterial or fungal infections comprises cause control, antimicrobial cure, supportive and adjunctive approaches with the help of various types of antimicrobials. Methodology: we conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE, from February 1986 to April 2017. The following search terms were used: perioperative surgical complications, post-operative infection after gastrointestinal surgery, antibiotics used in gastrointestinal surgery, MRSA in gastrointestinal surgery. This study aimed to explore the prevalence, prophylaxis and management of perioperative gastrointestinal infections and study about the types of antibiotics used for such management. Conclusion: better ways of post-operative management of infections must be studied such that the recommend use of antibiotics have full or specific coverage of pathogens and have minimal adverse effects
