When large polyps are involved, it may be useful to mark the polypectomy site with India ink (Figure 17). Site tattooing may help localize the area during subsequent surveillance colonoscopies and may assist the surgeon in locating the area to be resected. A,B, Endoscopic technique for marking a polypectomy site for subsequent surveillance. The most common complications of colonoscopy and polypectomy are bleeding or bowel perforation, which occurs in 0. When performing polypectomies of large polyps (Figure 18), use of excessive cautery may cause perforation or full wall thickness burn (postpolypectomy coagulation syndrome). A, B, C, Endoscopic technique for piecemeal removal of large polyp with a corresponding endoscopic view. Post-polypectomy Management Patients with only a small (<1cm) tubular adenoma do not have an appreciable increased risk of colorectal cancer and the general screening guidelines should be followed. For polyps larger than 1 cm or for multiple polyps, follow-up colonoscopies should be performed every year. In patients who have a suboptimal initial examination, colonoscopy should be repeated at 3 months. After one negative 1-year follow up, subsequent surveillance intervals may be increased to 3 years. If subsequent colonoscopy is not possible, a flexible sigmoidoscopy and an air contrast barium enema should be performed. However, it is important to individualize surveillance according to age and comorbidity of the patient. Surgical Therapy Colon Cancer the mainstay for the treatment of colorectal cancer is surgical resection. The goals of surgical therapy are to: 1 Remove the cancer completely with clear margins. The type of resection depends on a variety of factors including the location of the tumor, the presence of other associated cancers or polyps, the stage of the cancer, the risk of development of other colon cancer in the future, and finally, the patient’s preference. Some surgeons use manual suturing either in one or two layers, others prefer one of various stapling techniques. Colorectal resection, including regional lymph nodes, is based on the blood supply to the bowel (Figure 19). A right hemicolectomy (Figure 20) is the surgical procedure performed for patients with cancer between the cecum and ascending colon. A transverse colectomy (Figure 21) is performed for tumors in the transverse colon. The middle colic artery is ligated and the ascending and descending colon are anastomosed. Extended right colectomy is performed in cases in which the cancer is located in the proximal or mid transverse colon (Figure 22). This resection requires removal of the terminal ileum, cecum, ascending colon, hepatic flexure and a portion of the transverse colon. Left hemicolectomy (Figure 23) is the procedure for tumors of the descending colon. The left colic artery is ligated, the splenic flexure and descending colon removed and the transverse and upper sigmoid colon anastomosed. Rectal Cancer the surgical management of rectal cancer can be particularly complicated, depending on the location of the tumor. There are a variety of surgical procedures that are available to patients with rectal cancer ranging from local excision to radical abdominoperineal resection.

If you teach a course with a large number of discussion sections erectile dysfunction doctor los angeles order malegra dxt 130 mg amex, invite each section to erectile dysfunction recovery stories buy malegra dxt 130mg with visa select a delegate erectile dysfunction treatment atlanta buy malegra dxt 130 mg mastercard. Be sure, too, that the liaison students understand their function and encourage them to circulate and seek out information formally or informally from other students. The charge of the team is to identify problem areas and make suggestions for improve ment. Faculty who use this strategy have found it effective for improving course quality and are enthusiastic about the results (Kogut, 1984). Student teams have suggested improvements in procedural aspects of the course, instructors management style, course organization, readings, assignments, level and extent of student participation in discussion, board work, and pace of lecturing, among other topics. For a list of manuals on how to implement student management and resource teams and how to help students function effectively as team members, see Nuhfer, Perkins, Simonson, and Col leagues, 1992. If your campus has an electronic mail (e-mail) system, establish a computer account so that you can receive and send electronic mail. Let students know that if they have questions, concerns, or comments about the course, they can mail them directly to you. If you wish, you may also arrange for students to have individual accounts so that you can respond to their questions or comments. If you do institute electronic mail in your class, be prepared to answer queries daily. You can also write open letters to students throughout the course, inviting them to answer specific questions about the class. Of course, e-mail is not a replace ment for office hours; it is simply another way for faculty to hear from students. Voice mail and answering machines also permit students to register anonymous gripes. Place a manilla envelope in the back of the classroom, in the department office, or on your office door, and encour age students to drop off questions, comments, or problems. For other fast feedback ac tivities, such as e-mail or student teams, report back to the class as appropriate. Then consider their suggestions for improvement and group them into three categories: • Those you can change this semester (for example, the turnaround time on homework assignments) • Those that must wait until the next time the course is offered (for example, the textbook) • Those that you either cannot or, for pedagogical reasons, will not change (for example, the number of quizzes or tests) You may want to ask a colleague or a teaching consultant to help you identify options for making changes. Thank your students for their comments and invite their ongoing participation in helping you improve the course. Students appreciate know ing that an instructor has carefully considered what they have said. Clarify any confusions or misunderstandings about your goals and their expecta tions. Then give a brief account of which of their suggestions you will act upon this term, which must wait until the course is next offered, and which you will not act upon and why. For example, if students report that they are often confused, invite them to ask questions more often. Keep your tone and attitude neutral; avoid being defensive, indignant, or unduly apologetic. At the end of a class period, ask your students to write for a minute or two on the following two questions: "What is the most significant thing you learned today At the conclusion of a series of lectures or readings about a particular topic, ask students to write short phrases summarizing the three to five key concepts or main ideas about the topic. You can review these lists to verify whether your students have grasped the important ideas. You may want to initiate a class discussion that asks students to compare and contrast their entries or define and apply the concepts. During the last ten minutes of class, hand out a short questionnaire on the basic concepts covered that day. At the beginning of the class period, you can request oral or written paraphrases and then judge whether students have understood the assigned reading or the last lecture. Or you can request paraphrases at the end of the period to check on whether students understood the material you presented.
However erectile dysfunction doctor in karachi buy generic malegra dxt canada, there is a difference between “change management” and “change leadership” that’s not just a matter of semantics erectile dysfunction medicine in ayurveda buy genuine malegra dxt online. According to erectile dysfunction treatment dallas texas best purchase malegra dxt John Kotter, a leading management consultant, these terms are not interchangeable. Change management, which is the term most often used, refers to a set of basic tools or structures intended to keep any change effort under control. Change leadership, on the other hand, concerns the driving forces, visions, and processes that lead to the transformation of the organization. Change leadership is concerned with making the whole change process go faster, smarter, and more efficiently. Change management tends to be more associated—at least, when it works well—with smaller changes rather than a major transformation. Frequently, a challenging vision can stimulate movement, especially if the people in the organization are empowered to move forward. However, as good as change leadership can be in getting things moving, it also has the potential to get things a little bit out of control. It is impossible to ensure that everything happens in an expected or desired way at a time that is wanted. On the other hand, if leaders don’t constantly drive change, their organization will lose its effectiveness and its support from its stakeholders and funders. David Kolzow 232 Leaders and traditional managers tend to have different views of what change means. Traditional managers who are linked to the status quo frequently see change as a threat and as something that causes problems. Leaders, on the other hand, look forward to change as an opportunity to grow, to gain an advantage, and to attain excellence. In contrast to traditional management, leaders aim at movement and change, providing the opportunity to constantly reassess the organization and its goals and desired outcomes. A subsequent chapter in this book will focus on the differences between management and leadership, especially as it applies to local government agencies and nonprofit organizations. When you consider the components of successful organizational change the qualities of a transformative leader become clear: 227 • To begin with, successful change within an organization requires a clear and thorough understanding of what change truly means. Far too often, the leaders of an organization may have been thinking for a while about the need for a particular change but fail to communicate this 227. Instead, their energy is often spent crafting their message that announces the change. Very little effort may be made to involve all the members of the organization in understanding or agreeing with this need for change, how it will affect them personally and professionally, and how it will be implemented. The more that everyone is involved in looking at the options related to needed change and in suggesting ways to do things differently, the easier it will be to build the case for the next round of change. However, transformative change is not likely to occur if the staff is not on board to embracing this change. According to Ken Blanchard, the best way to initiate, implement, and sustain change is to increase the level of influence and involvement from the people being asked to change. As this process enfolds, the change leaders will need to ensure that any employee concerns are brought forth and resolved along the way. Resistance increases the more that people sense that they cannot influence what is happening to them. People who are left out of shaping change have a way of reminding us that they are really important. Robert Lee Facilitating Change Organization leaders need to recognize that people in the organization are likely to resist making major changes for a variety of reasons. These include fear of the unknown, a feeling of inadequacy to deal with the change, and whether the change will result in an adverse effect on their jobs. As was stated earlier, leaders must widely communicate the need for the change and how the change can be accomplished successfully. David Kolzow 234 change happens through good communication and collaboration, not by actions of the top leadership. It is also the responsibility of effective leaders to help people understand how this change will benefit each individual in the organization. Increasingly the leadership’s role is to interpret, communicate, and enable rather to instruct and impose, which nobody really responds to well.
