The reader is advised, however, to check the product information sheet accompanying each drug to be familiar with any changes in the dosage schedule or in the contra- indications. This advice should be taken with particular seriousness if the agent to be administered is a new one or one that is infre- quently used. Board Review from Medscape describes basic principles of diagnosis and therapy. Because of the uniqueness of each patient and the need to take into account a number of concurrent considerations, however, this information should be used by physicians only as a general guide to clinical decision making. Board Review from Medscape is derived from the ACP Medicine CME program, which is accredited by the University of Alabama School of Medicine and Medscape, both of whom are accredited by the ACCME to provide continuing medical education for physicians. Board Review from Medscape is intended for use in self-assessment, not as a way to earn CME credits. EDITORIAL BOARD Editor-in-Chief Janet B. Henrich, M.D. David C. Dale, M.D., F.A.C.P.

Cystic lesions located in the paravaginal region are rare. When present, paravaginal cysts are typically benign and are incidentally found on routine gynecological exams; however, rarely they can be malignant. Treatment options for paravaginal cancers are not well studied and early diagnosis may help improve prognosis in these patients. Our case describes a 55-year-old female with a recurrent paravaginal cyst that was remarkable for serous papillary adenocarcinoma despite biopsy and fuid cytology negative for malignancy.

  • Grading Evidence
    Grading Evidence Analysis of the colonoscopic findings in patients with rectal bleeding according to the pattern of their presenting symptoms Journal Diseases of the Colon & Rectum Publisher Springer New York ISSN 0012-3706 (Print) 1530-0358 (Online) Issue Volume 34, Number 5 / May, 1991 Abstract Patients presenting with rectal bleeding were prospectively categorized according to the pattern of their presentation into those with outlet bleeding (n=115), suspicious bleeding (n=59), hemorrhage (n=27), and occult bleeding (n=68). All patients underwent colonoscopy and this was complete in 94 percent. There were 34 patients with carcinoma and 69 with adenomas >1 cm diameter. The percentage of neoplasms proximal to the splenic flexure was 1 percent in outlet bleeding, 24 percent with suspicious bleeding, 75 percent with hemorrhage, and 73 percent with occult bleeding. Barium enema was available in 78 patients and was falsely positive for neoplasms in 21 percent and falsely negative in 45 percent. Colonoscopy is the investigation of choice in patients with suspicious, occult, or severe rectal bleeding. Bleeding of a typical outlet pattern may be investigated by flexible sigmoidoscopy.

Department of Surgery, Case Western Reserve University School of Medicine, Cleveland, Ohio 44106. Abstract Rectal bleeding is a frequent presenting symptom of a number of benign anorectal disorders. However, it may also be a warning sign of more significant gastrointestinal pathology. For this reason, full colonic evaluation has been recommended in patients with intermittent bright red rectal bleeding.

  • Mario's ITE Database V2010.007 Document Copy for the Sole
    Mario’s ITE database V2010.007 Document copy for the sole personal use of Dr. Mario Alberto Jimenez Mario’s Family Medicine In-Training Examination (ITE) Database One of the most important objectives in creating this database is to help the physician in organizing and associating topics to increase memorization efficiency and retention. Another important objective is to allow the physician to focus on any particular organ systems or clinical category he/she might be interested by using simple search queries. For instance, in order to search for the organ system category of Cardiovascular, you only need to press Shift+Ctrl+F, type the letters “Car” after a “+” sign in the search box, i.e. type: “+Car” (do not include “ ), and click the search button, or to search for the clinical category of Care of Children, you only need to type: “+Cca” in the search box and click the search button. The ITE database was exported to adobe acrobat format to ease portability, readability and searchability. Other search examples include: questions that more than 50% of residents missed, type “>L”. This database is based on memorization techniques described here: http://www.web-us.com/memory/improving_memory.htm, but if you have difficulty memorizing all that is written here, remember the warning from one of the smartest and most creative minds of our times, Albert Einstein: "the spirit of learning and creative thought are lost in strict rote learning."

  • Volume - X Issue - Lx Nov / Dec 2013
    VOLUME - X ISSUE - LX NOV / DEC 2013 In medicine, inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon 1 Editorial and small intestine. The major types of IBD are Crohn's disease and ulcerative colitis. Disease The main forms of IBD are Crohn's disease and ulcerative colitis (UC). Inflammatory bowel 2 Diagnosis diseases are considered autoimmune diseases, in which the body's own immune system attacks elements of the digestive system. 9 Interpretation Accounting for far fewer cases are other forms of IBD, which are not always classified as typical IBD: Collagenous colitis, Lymphocytic colitis, Ischaemic colitis, Diversion colitis, Behçet's disease, 10 Bouquet Indeterminate colitis. Trouble The main difference between Crohn's disease and UC is the location and nature of the 11 inflammatory changes. Crohn's can affect any part of the gastrointestinal tract, from mouth to anus Shooting (skip lesions), although a majority of the cases start in the terminal ileum. Ulcerative colitis, in contrast, is restricted to the colon and the rectum. Microscopically, ulcerative colitis is restricted to 12 Tulip News the mucosa (epithelial lining of the gut), while Crohn's disease affects the whole bowel wall ("transmural lesions"). Finally, Crohn's disease and ulcerative colitis present with extra-intestinal manifestations (such as liver problems, arthritis, skin manifestations and eye problems) in different proportions. Rarely, a definitive diagnosis neither of Crohn's disease nor of ulcerative colitis can be made because of idiosyncrasies in the presentation. In this case, a diagnosis of indeterminate colitis may be made. Although a recognised definition, not all centres refer to this.
