Most common reactions for aromatics involve replacement of ring . hydrogens. by other atoms or groups . (substitution reactions). Mechanism of Electrophilic Aromatic Substitution Reactions. Electrophile. In addition to substitution, alkyl halides can also undergo elimination reactions, which lead to the formation of alkenes.. As with substitution reactions, elimination reactions come in two mechanistic types:. DEFINITIONS AND TYPES. Revision:. DO NOT WRITE- FOR YOUR INFO ONLY. We have looked at the period table, what atoms are, elements and compounds. You have learnt that atoms can join to make compounds or molecules and that we can mix compounds to make new compounds…..these are chemical reactions. patients -. A . reproducible didactic conference for medical . students. Robert F. McFadden, MD. Alexandra H. Sawicki, PGY1 Emory University. Abstract. We . describe . a one hour interactive conference given during medical students’ psychiatry clerkship. We introduce a framework for examining, classifying, and understanding reactions to difficult patients. This exposes students destined for all medical specialties to a consistent method of examining patient interactions. This conference brings psychodynamically-oriented faculty into contact with the entire student body in the service of improving students’ ability to respond to, diagnose, and care for patients. Some medical schools have held group discussions of problematic patient encounters without a structured didactic component. Prior to our conference, taught once per clerkship, students are surveyed and asked to describe a troubling psychiatry patient encounter. Information is gathered about what troubles students, and how the students reacted. This retrospective survey encourages growth of students’ observing ego regarding their feelings and reactions as a physician. During the real-time conference, we teach students to distinguish between three types of reactions: justified reactions, projective identification reactions, and counter-transference reactions. We lead students through a problem-based learning exercise to practice applying this concept. Time is allowed for discussion of how this classification can guide students after a troubling patient encounter. This conference addresses the important, often ignored issue of students’ reactions to troubling patient encounters with a systematic and reproducible classification system that could be taught in an hour-long lecture at medical schools throughout the country. This will give students a lifelong protective layer of insight that will allow them to respond in healthier, more empathetic ways to patients..
