Digital Rectal Examination Clinical Examination Guide Digital Rectal Examination Background and orientation Digital Rectal Examination is an intimate examination that requires the presence of a chaperone. When conducted by a student, a qualified supervisor (who may also act as a chaperone) is also required. A key aspect of this examination is examining the patient in the left lateral position and keeping a running commentary all through the examination. The clock face is traditionally used to describe lesions found during digital rectal examination, with 12 o’clock noting the anterior position (vaginal/scrotal), 6 o’clock for the posterior aspect (spinal). Note the orientation when the patient is in the left lateral position Components of the examination • Introduction and explanations. • Gather equipment and PPE • External inspection • Internal palpation • Prostate examination • Conclusion Introduction and Explanations • Introduce yourself, confirm patient ID • Explain the following as part of gaining informed consent: - The nature of the examination using non-technical language – exposure, external inspection and internal examination with a single gloved finger. - That it should not be painful but may cause some discomfort - The need for a qualified supervisor who will also act as a chaperone. - The patient may choose an additional chaperone if they wish. • Explain the left lateral position (lying on the left side with knees together and pulled up close to abdomen, buttocks close to the edge of the bed, facing away from you).

  • Type II Familial Synpolydactyly: Report on Two Families with an Emphasis on Variations of Expression
    European Journal of Human Genetics (2011) 19, 112–114 & 2011 Macmillan Publishers Limited All rights reserved 1018-4813/11 www.nature.com/ejhg SHORT REPORT Type II familial synpolydactyly: report on two families with an emphasis on variations of expression Mohammad M Al-Qattan*,1 Type II familial synpolydactyly is rare and is known to have variable expression. However, no previous papers have attempted to review these variations. The aim of this paper was to review these variations and show several of these variable expressions in two families. The classic features of type II familial synpolydactyly are bilateral synpolydactyly of the third web spaces of the hands and bilateral synpolydactyly of the fourth web spaces of the feet. Several members of the two families reported in this paper showed the following variations: the third web spaces of the hands showing syndactyly without the polydactyly, normal feet, concurrent polydactyly of the little finger, concurrent clinodactyly of the little finger and the ‘homozygous’ phenotype. It was concluded that variable expressions of type II familial synpolydactyly are common and awareness of such variations is important to clinicians.

  • High Quality Fecal Occult Blood Testing (FOBT) for CRC Screening: Evidence and Recommendations
    High Quality Fecal Occult Blood Testing (FOBT) for CRC Screening: Evidence and Recommendations Rationale for use of FOBT High sensitivity fecal occult blood testing (FOBT) is one of the colorectal cancer screening methods recommended in guidelines from the American Cancer Society, the US Preventive Services Taskforce, and every other major medical organization. In spite of this widespread endorsement, primary care clinicians often express conviction that colonoscopy is the “gold standard” test for colorectal cancer screening and that the use of FOBT represents sub-standard care. These beliefs persist in spite of well-documented shortcomings of endoscopy (missed adenomas and cancers, higher complication rates and higher one-time costs than other screening methodologies), and the fact that access to endoscopy is limited or non- existent for a significant proportion of the U.S. population. Many clinicians are also unaware that randomized controlled trials of FOBT screening have demonstrated decreases in colorectal cancer incidence and mortality, and modeling studies suggest that the years of life saved through a high quality FOBT screening program are essentially the same as with a high quality colonoscopy based screening programs. Recent advances in stool blood screening include the emergence of new tests and improved understanding of the impact of quality factors on testing outcomes. This document provides state-of-the-science information about high quality stool testing. Types of Fecal Occult Blood Tests Two main types of FOBT are available – guaiac and immunochemical. Both types of FOBT have been shown to have reasonably high detection rates for colon and rectal cancers; adenoma detection rates are appreciably lower.

  • Circular Motion Review KEY 1. Define Or Explain the Following: A
    Circular Motion Review KEY 1. Define or explain the following: a. Frequency The number of times that an object moves around a circle in a given period of time. b. Period The amount of time needed for an object to move once around a circular path. c. Hertz The standard unit of frequency. 1 cycle/second (or 1 revolution per second) d. Centripetal Force The centrally directed force that causes an object’s tangential velocity to change direction as it moves around a circle. e. Centrifugal Force The imaginary outward force which you feel as you go around a turn in a car. This “force” is a consequence of you being accelerating and your brain interpreting your tendency to move in a straight line as a force. 2. Which of the following is NOT a property of Centripetal Force? a. It is unbalanced b. It always has a real source c. It is directed outward from the center of the circle d. Its magnitude is proportional to mass e. Its magnitude is proportional to the square of speed f. Its magnitude is inversely proportional to the radius of the circle g. It is the amount of force required to turn a particular object in a particular circle 3. If an object is swung by a string in a vertical circle, explain two reasons why the string is most likely to break at the bottom of the circle. 1. The string tension needs to overcome the weight of the object to provide the needed centripetal force. 2. The object is moving the fastest at the bottom unless some force keeps the object at a constant speed as it moves around the circle.

  • Emerald Observatory Is an Ipad™ Application Which Displays a Variety of Astronomical Information
    Emerald Observatory is an iPad™ application which displays a variety of astronomical information. It is similar in that way to our flagship products, Emerald Chronometer® and Emerald Chronometer HD, but designed from the start to take advantage of the iPad's larger display. Much of the supporting technology, including NTP (atomic time) and the highly accurate astronomical algorithms, was derived from Emerald Chronometer. Clock First of all, it's an ordinary clock. The main hands (gold colored) display the hours, minutes and seconds in the usual 12-hour format. To read it more precisely use the small numbers and tick marks on the inner edge of the rings. The thin central hand with the large white arrow head and the large white numbers and tick marks indicate the time in 24-hour format (with noon on top by default). Emerald Observatory's time may not exactly match the time in the iPad's status bar becausethe iPad's clock is often not very accurate whereas Emerald Observatory's time is synchronized with the international standard atomic clocks. This is usually accurate to about +/- 0.100 seconds. This is accomplished with the Network Time Protocol (NTP) so it must have a Net connection to get a sync. If the Net is not available, it will fall back to the internal clock's value. It is also possible to change the clock's time and to animate it at very high rates. See Set Mode, below. Moon In the upper left Emerald Observatory displays the Moon as it appears from the current location at the clock's time.

  • Colorectal Cancer
    Colorectal Cancer Colorectal cancer is the second most common cancer in the United States, striking 140,000 people annually and causing 60,000 deaths. That’s a staggering figure when you consider the disease is potentially curable if diagnosed in the early stages. Who is at risk? Though colorectal cancer may occur at any age, more than 90% of the patients are over age 40, at which point the risk doubles every ten years. In addition to age, other high risk factors include a family history of colorectal cancer and polyps and a personal history of ulcerative colitis, colon polyps or cancer of other organs, especially of the breast or uterus. How does it start? It is generally agreed that nearly all colon and rectal cancer begins in benign polyps. These pre-malignant growths occur on the bowel wall and may eventually increase in size and become cancer. Removal of benign polyps is one aspect of preventive medicine that really works! What are the symptoms? The most common symptoms are rectal bleeding and changes in bowel habits, such as constipation or diarrhea. (These symptoms are also common in other diseases so it is important you receive a thorough examination should you experience them.) Abdominal pain and weight loss are usually late symptoms indicating possible extensive disease. Unfortunately, many polyps and early cancers fail to produce symptoms. Therefore, it is important that your routine physical includes colorectal cancer detection procedures once you reach age 50. There are several methods for detection of colorectal cancer. These include digital rectal examination, a chemical test of the stool for blood, flexible sigmoidoscopy and colonoscopy (lighted tubular instruments used to inspect the lower bowel) and barium enema.

  • Benefit of Rectal Examination in Children with Acute Abdomen
    Benefit of Rectal Examination in Children with Acute Abdomen Wasun Nuntasunti MD*, Mongkol Laohapensang MD** * Department of Surgery, Sisaket Hospital, Sisaket, Thailand ** Department of Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand Background: Acute abdomen is a condition that often mandates urgent treatment. PR or DRE (per rectal examination or digital rectal examination) is one of the fundamental physical examinations that doctors use to differentiate causes of acute abdominal pain. However, it is not a pleasant examination to undergo. Sometimes doctors ignore this examination. The benefit of per rectal examination has rarely been studied in children. Objective: This study was designed to demonstrate the benefit of rectal examination for contribution to the diagnosis of acute abdominal pain in children and reduction of unnecessary operation. Material and Method: A prospective cross sectional study of children ages 3 to 15 years old who presented with acute abdominal pain from January 2012 to December 2013 was conducted. The clinical parameters including DRE results were correlated to the diagnosis. The diagnoses prior to and after DRE were compared. The accuracy of DRE was analyzed by pair response analysis of pre and post-DRE results using McNemar‘s Chi-square test. Results: A total of 116 children with acute abdominal pain were enrolled in the study. The final diagnoses were appendicitis accounting for 27%, constipation 28%, non-surgical gastrointestinal diseases such as gastritis, diarrhea and food poisoning 9%, diseases of the female reproductive system 7% and others 29%. In comparing the diagnoses prior to and after digital rectal examination, it was demonstrated that rectal examination significantly helped differentiate diagnosis in 38.8% of patients, whereas 19% of the patients gained no benefit.DRE corrected the diagnosis in 45 cases which was significantly higher than misguiding the diagnosis in 3 cases.
