BACKGROUND: It is assumed that recreational use of methamphetamine can trigger acute myocardial infarction (AMI) events, but estimates of longitudinal hazards of AMI among methamphetamine users are lacking. METHODS: Retrospective cohort study: Competing-risks analysis was used to estimate time-to-AMI patterns in methamphetamine versus matched appendicitis (population-proxy) and matched cocaine (drug-control) groups. Cohorts were propensity-score-matched using demographic and clinical variables...

Background: Metronidazole is traditionally dosed every 6-8 hours even though in adults it has a long half-life, concentration-dependent killing, and 3-hour postantibiotic effect. Based on this logic, some pediatric hospitals adopted once-daily dosing for appendicitis, despite limited pharmacokinetics-pharmacodynamics (PK/PD) in children. We studied pediatric patients with appendicitis given metronidazole once daily to determine whether this dosing would meet target area under the curve (AUC)/minimum inhibitory concentration (MIC) ratio of ≥70 for Bacteroides fragilis...

BACKGROUND: Delays in surgery for patients with acute appendicitis may increase the risk of perforation and complications. These risks must be balanced with the theoretical risk of night time operations. OBJECTIVE: To determine the effect of (i) time of day of surgery and (ii) time between triage presentation and surgery, on surgical complications in patient undergoing appendectomy for appendicitis. METHODS: Population level data from Ontario from 2009 - 2015 was used to conduct this retrospective cohort study...

We present a case of appendicitis within a De Garengeot hernia. The patient presented to the emergency department with 4 days of worsening abdominal pain. Computed tomography examination revealed an inflamed appendix within a femoral hernia. The patient underwent appendectomy and repair of the femoral defect. Pathological examination was consistent with acute appendicitis. De Garengeot hernia is a rare phenomenon, with less than 5% of femoral hernias containing the appendix and 0.08% to 0.13% containing an incarcerated acute appendicitis...

BACKGROUND: Acute appendicitis (AA) is a momentous, emergency, surgical pathology that has still been investigated for both etiopathogenetic unknowns and challenges in diagnosis. Presently, there is little information about the role of microRNAs (miRNAs), which have basic biological functions in the cell, can be a marker, and are associated with various pathologies, in patients with AA. The aim of this study was to investigate the expressions of some miRNAs in AA. METHODS: Overall, 41 miRNAs were screened in 48 individuals comprising 24 patients with AA and 24 healthy controls at Erciyes University Genome and Stem Cell Center (GENKOK)...

INTRODUCTION: Diverticula of the appendix (DA) have a reported incidence of up to 2.1%. They are primarily detected incidentally, through imaging and intraoperative or histologic diagnosis. This study's objective was to examine the prevalence of DA, and its relationship with inflammation and neoplasia, as well as review the literature with respect to clinical outcomes and ability to identify DA preoperatively. METHODOLOGY: A retrospective search of all patients undergoing an appendicectomy for right lower quadrant pain at a single institution between 2004 and 2017 was conducted...

INTRODUCTION: Fecal appendicular peritonitis (FAP) is a poorly studied, rare form of acute appendicitis, corresponding to peritoneal inflammation with the presence of feces secondary to ruptured appendix. The purpose of this study was to describe FAP and to compare FAP with purulent appendicular peritonitis (PAP). PATIENTS AND METHODS: This single-center, retrospective study was conducted in consecutive patients to compare the FAP group and the PAP group. The primary endpoint was the 30-day postoperative morbidity and mortality according to the Clavien-Dindo classification...

BACKGROUND: The World Society for Emergency Surgery determined that for appendicitis managed with appendectomy, there is a paucity of evidence evaluating costs with respect to disease severity. The American Association for the Surgery of Trauma (AAST) disease severity grading system is valid and generalizable for appendicitis. We aimed to evaluate hospitalization costs incurred by patients with increasing disease severity as defined by the AAST. We hypothesized that increasing disease severity would be associated with greater cost...

BACKGROUND: Acute appendicitis is a common pediatric surgical emergency; however, there are few grading systems to assign disease severity. The American Association for the Surgery of Trauma (AAST) recently developed a grading system for a variety of emergency surgical conditions, including appendicitis. The severity of acute appendicitis in younger patients in KwaZulu-Natal (South Africa) is unknown. We aimed to describe the disease severity in this patient population using the AAST grading system hypothesizing that the AAST grade would correlate with morbidity, management type, and duration of stay...

OBJECTIVES: Appendicitis is a common surgical condition that frequently requires diagnostic imaging. Abdominal computed tomography (CT) is the gold standard for diagnosing appendicitis. Ultrasound offers a radiation-free modality; however, its availability outside business hours is limited in many emergency departments (EDs). The purpose of this study is to evaluate the test characteristics of emergency physician-performed point-of-care ultrasound (POCUS) to diagnose appendicitis in a Canadian ED...

Primary malignancies of the appendix are rare. Of these, less than 5% are goblet cell carcinoid (GCC) tumours. The majority of GCC present with findings of acute appendicitis or advanced peritoneal spread. We describe a rare presentation of GCC as subtle mucosal abnormality of the appendiceal orifice seen on colonoscopy performed for iron-deficiency anaemia. Biopsies were interpreted as adenocarcinoma; however, final surgical pathology confirmed GCC of the appendix with caecal involvement. The patient recovered well from surgery, anaemia resolved and follow-up did not show metastatic disease...

BACKGROUND AND AIMS: Appendectomy is a common surgical procedure, but no overview of the long-term consequences exists. Our aim was to systematically review the long-term complications of appendectomy for acute appendicitis. MATERIALS AND METHODS: This systematic review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A protocol was registered on PROSPERO (CRD42017064662). The databases PubMed and EMBASE were searched for original reports on appendectomy with n ≥ 500 and follow-up >30 days...

Introduction: Clinical ultrasound (CUS) is highly specific for the diagnosis of acute appendicitis but is operator-dependent. The goal of this study was to determine if a heterogeneous group of emergency physicians (EP) could diagnose acute appendicitis on CUS in patients with a moderate to high pre-test probability. Methods: This was a prospective, observational study of a convenience sample of adult and pediatric patients with suspected appendicitis. Sonographers received a structured, 20-minute CUS training on appendicitis prior to patient enrollment...

Background and study aims  Clip-assisted endoscopic full-thickness resection has great potential for treatment of difficult-to-resect colorectal neoplasia. Here, we report on endoscopic full-thickness resection at the appendiceal orifice with the appendix in situ requiring emergency surgery due to acute appendicitis. Final histopathology showed appendicitis and residual serrated adenoma within the appendiceal stump, but unexpectedly, also a displaced adenoma fragment at the serosal surface of the cecum. Given the transmural placement of the clip prior to snare resection, translocation of neoplastic tissue to the extra luminal site in cases of incomplete adenoma/carcinoma resection could be a concern...

Introduction: Recurrent appendicitis is a disease process, distinct from acute appendicitis, which occurs with an approximate incidence of 10%. This clinical entity can pose diagnostic and therapeutic dilemma for clinicians resulting in delayed diagnosis and severe complications. Presentation of case: Herein, we described a case of recurrent appendicitis with a history of 18 years of right lower quadrant (RLQ) abdominal pain with very mild tenderness that we encountered in our hospital in January 2016, which has been misjudged as other abdominal conditions and got complete relief after appendectomy...

REVIEW
Giovanni Maconi, Laura Obici, Stefania Carmagnola, Stefano Guzzetti
Autoinflammatory diseases (AIDs) usually present with acute abdominal pain and fever, both of which are also the main causes of referral in the emergency department. As some patients with acute abdominal pain may be discharged from the emergency department without a definitive diagnosis, it is not surprising that, due to their rarity, most cases of AID remain undiagnosed or are misdiagnosed as acute appendicitis. Indeed, the diagnosis of familial Mediterranean fever and autoinflammatory syndromes requires a high index of suspicion and careful assessment of clinical history...

BACKGROUND: Appendectomy, the surgical removal of the appendix, is performed primarily for acute appendicitis. Patients who undergo appendectomy for complicated appendicitis, defined as gangrenous or perforated appendicitis, are more likely to suffer from postoperative complications. The routine use of abdominal drainage to reduce postoperative complications after appendectomy for complicated appendicitis is controversial.This is an update of the review first published in 2015. OBJECTIVES: To assess the safety and efficacy of abdominal drainage to prevent intra-peritoneal abscess after open appendectomy for complicated appendicitis...

OBJECTIVE: The aim of this study was to evaluate the ability of emergency physicians with various levels of Point of Care Ultrasound (POCUS) experience to detect appendicitis with POCUS among children visiting a pediatric Emergency Department (ED). METHODS: A prospective cohort study was conducted in an urban, tertiary care pediatric ED. Children aged 2 to 18 years old who presented with acute abdominal pain suggesting appendicitis were included. Patients were excluded if they had a history of appendectomy, hemodynamic instability requiring resuscitation, or were transferred with proven diagnosis of appendicitis...
