Medical education is perceived as being stressful, and a high level of stress may have a negative effect on cognitive functioning and learning of students in a medical school. This cross-sectional study was conducted to determine the prevalence of stress among medical students and to observe an association between the levels of stress and their academic performance, including the sources of their stress. All the medical students from year one to year five levels from the College of Medicine, King Saud University, were enrolled in the study. The study was conducted using Kessler10 psychological distress (K10) inventory, which measures the level of stress according to none, mild, moderate, and severe categories. The prevalence of stress was measured and compared with the five study variables, such as gender, academic year, academic grades, regularity to course attendance, and perceived physical problems. The response rate among the study subjects was 87% (n=892). The total prevalence of stress was 63%, and the prevalence of severe stress was 25%. The prevalence of stress was higher (p<0.5) among females (75.7%) than among males (57%) (odds ratio=2.3, χ2=27.2, p<0.0001). The stress significantly decreased as the year of study increased, except for the final year. The study variables, including being female (p<0.0001), year of study (p<0.001), and presence of perceived physical problems (p<0.0001), were found as independent significant risk factors for the outcome variables of stress. Students' grade point average (academic score) or regularity to attend classes was not significantly associated with the stress level. The prevalence of stress was higher during the initial three years of study and among the female students. Physical problems are associated with high stress levels. Preventive mental health services, therefore, could be made an integral part of routine clinical services for medical students, especially in the initial academic years, to prevent such occurrence.

Increased PAI and PRI after orthodontic treatment correlated with the quality of endodontic treatment.

Patient: Male, 16-year-old Final Diagnosis: Splenic epidermoid cyst Symptoms: Abdominal asymmetry • abdominal distention • decreased oral intake Medication: — Clinical Procedure: Open splenectomy Specialty: Surgery Objective: Rare coexistence of disease or pathology Background: Splenic epidermoid cysts rarely occur and the majority of cases are discovered incidentally. However, large cysts can present with symptoms due to mass effect. Splenectomy is the treatment indicated for most splenic cysts and definitive diagnosis can only be made after histopathological examination. Case Report: A 16-year-old boy was referred to the general surgery clinic from a local hospital with a history of abdominal asymmetry, distention, decreased oral intake, and early satiety. Abdominal computed tomography (CT) was performed and revealed a large splenic mass measuring 18.4×14×17.4 cm with multiple mural calcifications at the rim. The mass was displacing the stomach, jejunal loops, pancreas, left kidney, and transverse colon. Preoperative biopsy was not possible because a parasitic cyst was suspected; therefore, splenectomy was performed through midline laparotomy. The patient recovered well, with no complications except for transient reactive thrombocytosis. Histopathology was reported as benign epithelial cysts, with the most likely diagnosis being a splenic epidermoid cyst. Subsequently, the patient was followed up at the surgery clinic. During the last outpatient visit, the patient exhibited good recovery with no problems. Conclusions: Large splenic epidermoid cysts are rare, particularly in the pediatric population. Nonspecific clinical and radiological findings are hurdles to an accurate diagnosis. Preoperative diagnosis is crucial to determine the type of intervention. However, a final diagnosis can only be made after histopathological examination.
