To analyze the low to medium distractor efficiency items in a multiple-choice question (MCQ) paper for item writing flaws. ⋯ Analyzing the low to medium DE items for item writing flaws, provides valuable information about item writing errors which negatively impact the distractor efficiency.
-
To investigate the effect of pan retinal photocoagulation (PRP) on Optic nerve head blood flow with OCT angiography in patients with proliferative diabetic retinopathy. ⋯ OCT angiography revealed there is significantly reduced optic nerve head blood flow in PRP treated eyes compared to non-PRP treated eyes.
-
To assess maternal and fetal morbidity associated with placenta previa and morbidly adherent placenta (MAP). ⋯ MAP is a dreadful complication of placenta previa with increased maternal morbidity. Regular antenatal care with adequate arrangement of blood transfusion and multidisciplinary approach can reduce maternal mortality.

Case Reports
Transient contrast induced neurotoxicity after coronary angiography: A contrast re-challenge case.
Contrast induced neurotoxicity (CIN) is a rare complication of cardiac catheterization and re-exposure to contrast medium carries the risk of recurrent CIN. We report a case of successful contrast re-challenge in a 60-year-old female patient who developed CIN after her first procedure of coronary angiography (CAG) which resulted in symptoms of disorientation, amnesia and cortical blindness. ⋯ Patient's symptoms resolved completely after 72 hours. Two months later, because of persistent exertional angina, patient was successfully re-challenged with lesser amount of contrast medium with administration of hydrocortisone prior to procedure, and PCI to LAD was completed without recurrence of CIN.

To explore the role of musculoskeletal ultrasound (MSUS) in the differential diagnosis of gouty arthritis (GA) and rheumatoid arthritis (RA) and to analyze the ultrasound imaging features of the two diseases. ⋯ MSUS has certain diagnostic value in the differentiation of GA and RA. Moreover, the two conditions have their own ultrasound imaging features.
