Class attendance and cardiology examination performance: a study in problem-based medical curriculum.

BACKGROUND AND AIMS: Information on the effect of students' class attendance on examination performance in a problem-based learning medical curriculum is limited. This study investigates the impact of different educational activities on students' academic performance in a problem-based learning curriculum. METHODS: This is a retrospective cohort study conducted on the cardiology block at the College of Medicine, King Saud Bin Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia. All students who undertook the cardiology block during the academic year 2011-2012 were included. The students' attendance was measured using their overall attendance percentage. This percentage is a product of their attendance of many activities throughout the block. The students' performance was assessed by the final mark obtained, which is a product of many assessment elements. Statistical correlation between students' attendance and performance was established. RESULTS: A total of 127 students were included. The average lecture attendance rate for the medical students in this study was found to be 86%. A significant positive correlation was noted between the overall attendance and the accumulated students' block mark (r=0.52; P<0.001). Students' attendance to different education activities was correlated to their final mark. Lecture attendance was the most significant predictor (P<0.001), that is, 1.0% increase in lecture attendance has predicted a 0.27 increase in students' final block mark. CONCLUSION: Class attendance has a positive effect on students' academic performance with stronger effect for lecture attendance compared to attendance in other teaching modalities. This suggests that lecture attendance is critical for learning even when a problem-based learning medical curriculum is applied.

Prevalence and characteristics of abnormal Papanicolaou smear in Central Saudi Arabia.

OBJECTIVES: To assess the prevalence and characteristics of abnormal pap smear in the central region of Saudi Arabia. METHODS: In this retrospective case control study conducted in the Departments of Obstetrics and Gynecology, and Histopathology at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia, all pap smears screened for Saudi women between 2008 and 2011 were reviewed. Approximately 5000 pap smears are screened annually at King Abdulaziz Medical City utilizing the Bethesda III System (2001). All abnormal smears patients' data were collected and compared to the data of randomly selected 200 normal smears' patients. RESULTS: Abnormal pap smear prevalence was found to be 4.3% (841/19,650 Saudi patients were found with atypical epithelial cells abnormalities). Its prevalence in the years 2008 was 5.7%, 2009 was 4.9%, 2010 was 4.2%, and 2011 was 2.5%. Abnormal smear patients have lower parity (p=0.001), and were less likely to use intra-uterine devices (p=0.03) compared with normal smear patients. Presence of abnormal cervical appearance was associated with increased epithelial cell abnormalities (p=0.045). The only positive history that has characterized patients with epithelial cell abnormalities was their previous history of abnormal pap smear (p=0.001). Squamous cell abnormalities were identified in 91% of the patients (767/841), and glandular cell abnormalities were identified in 9% of the patients (74/841). CONCLUSION: Prevalence of abnormal pap smears in central Saudi Arabia is relatively low, while advanced glandular abnormalities prevalence was observed to be high. 

Maternal and neonatal risk factors for early-onset group B streptococcal disease: a case control study.

OBJECTIVES: To identify the prominent maternal and neonatal risk factors associated with early-onset group B streptococcus (EOGBS) disease in neonates and to determine their importance by comparing them with a control group. SETTING: Neonatal unit at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia. PATIENTS: Cases were infants <7 days of age with invasive group B streptococcus (GBS) disease diagnosed between January 1, 2000 and December 31, 2009. Controls were healthy infants born in the same hospital during the same period having the same birth weight and gestational age category. MAIN OUTCOME MEASURES: Maternal risk factors for developing EOGBS disease, feto-maternal and neonatal clinical data, their morbidities, mortalities, and length of hospital stay. RESULTS: A total of 99 cases and 200 controls were included. The majority of cases presented in the first 72 hours of life (62/99 [63.9%]), of which 87/99 (89.7%) had at least one clinical risk factor for the development of EOGBS disease. Mothers of neonates with EOGBS disease were more likely to have GBS bacteriuria (odds ratio [OR] 10.76, 95% confidence interval [CI] 1.24-93.42), infection in the peripartum period (OR 8.92, CI 2.87-27.68), and temperature ≥38°C (OR 7.10, CI 2.50-20.17). GBS disease was associated with premature rupture of membranes and fetal tachycardia (P<0.01 for both). Neonates with EOGBS disease were more likely to have respiratory distress disease and convulsions, require tube feeding, and have longer hospital stays compared with the controls (P<0.01 for all). Stepwise multiple logistic regression has identified three risk factors that were associated with the highest tendency for the development of EOGBS disease. These were lack of antenatal attendance (OR =0.30 and CI 0.98-0.88), rupture of membranes (OR =9.62 and CI 3.1-29.4), and antibiotic use in labor (OR =0.16 and CI 0.38-0.67). CONCLUSION: A number of maternal risk factors were significantly associated with EOGBS disease. Taking these factors into consideration may result in preventing the occurrence of EOGBS disease, improve maternal and neonatal medical care, decrease their hospital stay, and reduce unnecessary hospital resource utilization.
