We report a case of rapidly proliferative glomerulonephritis in a patient with secondary syphilis. A 40-year-old male with a history of human immunodeficiency virus (HIV), chronic hepatitis B virus, and chronic kidney disease stage 2 presented with fatigue, anorexia, weight loss, arthralgia, chills, and rash throughout the body. The patient was non-compliant with HIV medication and had unprotected sexual intercourse. Labs showed blood urea nitrogen of 57 mg/dL (range 7-23 mg/dL), creatinine 8.2 mg/dL (range 0.5-1.3 mg/dL), and high titers of rapid plasma reagin. The biopsy showed crescentic glomerulonephritis with c3 deposition in mesangium and basement membrane. The patient responded to treatment with penicillin therapy with gradual improvement in kidney function. Presenting material in a manner that is most palatable to students is important to improve the learning process. We evaluated the efficacy of different teaching styles including the flipped classroom and assessed the learning style preferences of a cohort of medical learners in a preclinical obstetrics and gynecology course. We conducted three teaching sessions with 35 physician assistant students. A different teaching style was implemented for each session including a traditional lecture with interactive learning technology augmentation, a flipped classroom, and a hybrid approach incorporating lecture and group work. Students were surveyed using a Likert scale regarding the efficacy of the format, clinical relevance of the material, and their learning preference for future sessions. Students rated the traditional approach as the most effective, most relevant, and most preferred method. Students preferred the flipped classroom least, but they rated it as slightly more effective and relevant than the hybrid app
