The pathologist is a physician specializing in rendering medical diagnoses by examination of tissues and fluids removed from the body treatment jammed finger cheap indinavir 400 mg without prescription. These are less common now treatment quadricep strain purchase generic indinavir on line, since the development of fine needle aspiration (see below) pure keratin treatment purchase indinavir pills in toronto. Some types of tumors (such as lymphoma, a cancer of the lymphocyte blood cells) have to be examined whole to allow an accurate diagnosis, so enlarged lymph nodes are good candidates for excisional biopsies. Some surgeons prefer excisional biopsies of most breast lumps to ensure the greatest diagnostic accuracy. Some organs, such as the spleen, are dangerous to cut into without removing the whole organ, so excisional biopsies are preferred for these. This type of biopsy is most commonly used for tumors of the soft tissues (muscle, fat, connective tissue) to distinguish benign conditions from malignant soft tissue tumors, called sarcomas. It is done through a fiberoptic endoscope the doctor inserts into the gastrointestinal tract (alimentary tract endoscopy), urinary bladder (cystoscopy), abdominal cavity (laparoscopy), joint cavity (arthroscopy), mid-portion of the chest (mediastinoscopy), or trachea and bronchial system (laryngoscopy and bronchoscopy), either through a natural body orifice or a small surgical incision. The endoscopist can directly visualize an abnormal area on the lining of the organ in question and pinch off tiny bits of tissue with forceps attached to a long cable that runs inside the endoscope. Colposcopic biopsy this is a gynecologic procedure that typically is used to evaluate a patient who has had an abnor pathologist. These are smeared on a slide, stained, and examined under a microscope by the pathologist. Punch biopsy this technique is typically used by dermatologists to sample skin rashes and small masses. Hematologists do bone marrow biopsies all the time, but most internists and pathologists and many family practitioners are also trained to perform this procedure. With the patient lying on his/her stomach, the skin over the biopsy site is deadened with a local anesthetic. The needle is then inserted deeper to deaden the surface membrane covering the bone (the periosteum). A larger rigid needle with a very sharp point is then introduced into the marrow space. This suction step is occasionally uncomfortable, since it is impossible to deaden the inside of the bone. The contents of the syringe, which to the naked eye looks like blood with tiny chunks of fat floating around in it, is dropped onto a glass slide and smeared out. After staining, the cells are visible to the examining pathologist or hematologist. This part of procedure, the aspiration, is usually followed by the core biopsy, in which a slightly larger needle is used to extract core of bone. Even though the core biopsy procedure involves a bigger needle, it is usually less painful than the aspiration. Histologic sections this involves preparation of stained, thin (less than 5 micrometers, or 0. Permanent sections this technique gives the best quality of specimen for examination, at the expense of time. The fresh specimen is immersed in a fluid called a fixative for several hours (the necessary time dependent on the size of the specimen). The fixed specimen is then placed in a machine that automatically goes through an elaborate overnight cycle that removes all the water from the specimen and replaces it with paraffin wax.

Researchers Claxton and Murrell (1987) have grouped various models of learning styles into four general categories medications j tube cheap indinavir 400 mg with visa. Personality models refer to medicine hat college generic indinavir 400 mg with visa basic personality characteristics (for example symptoms urinary tract infection cheap indinavir 400mg amex, extrovert versus introvert). Social-interaction models focus on how students interact and behave in the classroom (for example, learning oriented versus grade oriented). Instructional preference models focus on the medium in which learning occurs (for example, listen ing, reading, direct experience). Instead, the focus here is on two of the better-researched models and their applications to improving instruction. An understanding of learning styles and orientations may enhance your teaching effectiveness: students may be more satisfied and more productive if they are studying with methods compatible with their styles (Cross, 1976; Matthews, 1991). Helping Students Learn and self-regulated learners by coaching them on how to improve their reading comprehension and retention, how to take notes, how to participate in class discussions, and how to study for tests. Ann Arbor: Center for Research on Learning and Teaching, Univer sity of Michigan, 1969. Collaborative team work and projects undertaken by heterogeneous groups encourage higher-order thinking and problem solving. For example, let students know what the important points are ("Be sure to underline this concept"). In addition to making comments to individual students, you can photocopy examples of good papers or hand out solutions to problem sets so that students can compare their performance to a standard. Most students tend to increase their effort in response to praise and encouragement rather than reprimands. Students who understand the demands of a given learning task and who consciously select appropriate learning strategies learn more effectively. Research shows that learning strategies can be taught to students (McKeachie, Pintrich, Lin, and Smith, 1986). You can help your students become more self-reflective 782 Helping Students Learn about the subject. This framework also affects which aspects of the new material they pay attention to and how they organize that new material. If you can relate what you are teaching to something already meaningful, relevant, or important to students, they are more likely to understand and remember the new material. In all courses, you can encourage students to draw connections between what they already know and what they are learning. So try to limit the number of new points you make in any single presentation to three or four. Broad concepts are more easily understood and remembered and are more meaningful than facts or details. Students learn best by doing, writing, discussing, or taking action, because active learning situations provide opportunities for students to test out what they have learned and how thoroughly they understand it. For example, discussions give students a chance to check their thinking with each other and to articulate their ideas clearly enough to prevent being misunderstood. Provide frequent oppor tunities for students to actively restate or apply key concepts. The more frequently students apply new concepts to different situations, the better they will be able to remember and use those new concepts. Let students summarize, paraphrase, or generalize about the important ideas in your class through group discussions, skits, role playing, simulations, case studies, and written assignments. Internships, field work, and hands-on activities provide a bridge between abstract and concrete learning and can free some students from strongly held or simplistic posi tions. Students may need guidance, empa thy, and understanding as they face the anxiety of appreciating multiple points of views, making wrong decisions, and dealing with uncertainties that lie beyond either-or thinking.
