  • Clinical Characteristics and Incidence of Perianal Diseases in Patients with Ulcerative Colitis
    Annals of Original Article Coloproctology Ann Coloproctol 2018;34(3):138-143 pISSN 2287-9714 eISSN 2287-9722 https://doi.org/10.3393/ac.2017.06.08 www.coloproctol.org Clinical Characteristics and Incidence of Perianal Diseases in Patients With Ulcerative Colitis Yong Sung Choi1, Do Sun Kim2, Doo Han Lee2, Jae Bum Lee2, Eun Jung Lee2, Seong Dae Lee2, Kee Ho Song2, Hyung Joong Jung2 Departments of 1Gastroenterology and 2Surgery, Daehang Hospital, Seoul, Korea Purpose: While perianal disease (PAD) is a characteristic of patients with Crohn disease, it has been overlooked in pa- tients with ulcerative colitis (UC). Thus, our study aimed to analyze the incidence and the clinical features of PAD in pa- tients with UC. Methods: We reviewed the data on 944 patients with an initial diagnosis of UC from October 2003 to October 2015. PAD was categorized as hemorrhoids, anal fissures, abscesses, and fistulae after anoscopic examination by experienced proctol- ogists. Data on patients’ demographics, incidence and types of PAD, medications, surgical therapies, and clinical course were analyzed. Results: The median follow-up period was 58 months (range, 12–142 months). Of the 944 UC patients, the cumulative in- cidence rates of PAD were 8.1% and 16.0% at 5 and 10 years, respectively. The incidence rates of bleeding hemorrhoids, anal fissures, abscesses, and fistulae at 10 years were 6.7%, 5.3%, 2.6%, and 3.4%, respectively. The cumulative incidence rates of perianal sepsis (abscess or fistula) were 2.2% and 4.5% at 5 and 10 years, respectively. In the multivariate analyses, male sex (risk ratio [RR], 4.6; 95% confidence interval [CI], 1.7–12.5) and extensive disease (RR, 4.2; 95% CI, 1.6–10.9) were significantly associated with the development of perianal sepsis.

  • Perianal Abscess in a 2-Year-Old Presenting with a Febrile Seizure and Swelling of the Perineum Gregory M
    Oxford Medical Case Reports, 2019;01, 26–28 doi: 10.1093/omcr/omy116 Case Report CASE REPORT Perianal abscess in a 2-year-old presenting with a febrile seizure and swelling of the perineum Gregory M. Taylor, DO* and Andrew H. Erlich, DO Emergency Medicine Physician, Beaumont Hospital, Teaching Hospital of Michigan State University, Department of Emergency Medicine, Farmington Hills, MI, USA *Correspondence address. Beaumont Hospital, Teaching Hospital of Michigan State University, Farmington Hills, MI, USA. E-mail: Gregory.Taylor@ Beaumont.org Abstract An anorectal abscess, specifically a perianal abscess, is a relatively uncommon infection in children. It is a purulent fluid collection under the soft tissue outside the anus. Some of these abscesses may spontaneously drain and heal by themselves, while others may result in sepsis and require surgical intervention. The transition to a systemic illness requiring hospital admission is considered rare. We present the case of a 2-year-old male presenting with a febrile seizure and found to be systemically ill secondary to a perianal abscess. To our knowledge, this is the first case reported in the literature of a febrile seizure secondary to a perianal abscess. INTRODUCTION Vitals on arrival to the ED were as follows: 103.1°F, blood pressure of 96/78 mmHg, respiratory rate 27 breaths/min, heart A perianal abscess occurs most often in male children <1 year rate 126 beats/min, weight 12.8 kg and 100% oxygen saturation of age; however, they can occur at any age and in either sex [1]. on room air. As soon as he was brought back to the treatment In one study, an incidence was reported of up to 4.3% [1].

Kennedy Boulevard Suite 860 Philadelphia, PA 19103 1-877-825-9106 [email protected] www.surgicalcore.org SCORE Curriculum Outline for General Surgery The SCORE® Curriculum Outline for General Surgery is a list of topics to be covered in a five- year general surgery residency program. The outline is updated annually to remain contempo- rary and reflect feedback from SCORE member organizations and specialty surgical societies. Topics are listed for all six competencies of the Accreditation Council for Graduate Medical Education (ACGME): patient care; medical knowledge; professionalism; interpersonal and communication skills; practice-based learning and improvement; and systems-based practice. The patient care topics cover 27 organ system- based categories, with each category separated into Diseases/Conditions and Operations/ Procedures. Topics within these two areas are then designated as Core or Advanced. Changes from the previous edition are indi- cated in the Excel version of this outline, avail- able at www.surgicalcore.org. Note that topics listed in this booklet may not directly match those currently on the SCORE Portal — this outline is forward-looking, reflecting the latest updates. The Surgical Council on Resident Education (SCORE) is a nonprofit consortium formed in 2006 by the principal organizations involved in U.S. surgical education. SCORE’s mission is to improve the education of general surgery residents through the development of a national curriculum for general surgery residency training.

  • General Surgery for Family Medicine Residents
    GENERAL SURGERY FOR FAMILY MEDICINE RESIDENTS PROGRAM LIAISON: Dr.Randy Szlabick INSTITUTION(S): Altru Hospital LEVEL(S): PGY-1-PGY-5 I. GENERAL INFORMATION The General Surgery Department at Altru Clinic has six full-time staff surgeons specializing in the treatment of various surgical conditions. In keeping with the educational philosophy of the Surgical Department, we would like the residents to obtain a broad, in-depth experience while on the surgical rotation. While the resident will be assigned to various surgeons on specific days, we would like them to make as much use of their experience as possible, while preserving an adequate outpatient clinical exposure a minimum of one day per week. While there are some variations in particular patient mixes that each surgeon is seeing, exposure to a wider group of individuals will be that the resident will be involved in the pre-operative, intra-operative, and post-operative care of general surgical patients. II. GOALS & OBJECTIVES PGY-1 Resident Knowledge Ability to perform a detailed and comprehensive history and physical exam Differential diagnosis of acute abdominal pain Ability to detect soft tissue infection Differential diagnosis of leg pain Differential diagnosis of swelling of the extremity Differential diagnosis of chest pain Differential diagnosis of respiratory distress Understanding of normal post-operative recovery Principles of wound healing Ability to detect electrolyte abnormalities, anemia and coagulopathy Understanding principles of enteral and parental nutrition
