Purpose To determine the incremental value of clinical data in patients with ultrasonographic (US) examinations that were interpreted as being equivocal for acute appendicitis. Materials and Methods Institutional review board approval, with a waiver of informed consent, was obtained for this analysis of clinical and imaging data in patients younger than 18 years old who were evaluated for acute...

BACKGROUND Nonperforating appendicitis is primarily a disease of children, and nonperforating diverticulitis affects mostly older adults. Apart from these age differences, the diseases share many epidemiological features, such as association with better hygiene and low-fiber diets. HYPOTHESIS Nonperforating appendicitis and nonperforating diverticulitis are different manifestations of the sam...

The diagnosis of acute appendicitis can be somewhat obscure in a patient that presents with right lower quadrant abdominal pain. The advancement and ease of imaging have made CT scanning readily available in the emergency department. Management can be challenging when the patient has a high likelihood of appendicitis based on clinical suspicion and negative CT scan. The purpose of this case rep...

A variety of bacterial species play a major role in appendicitis. Both aerobic and anaerobic gram positive and gram negative bacteria such as, Bacteroides fragilis, Streptococcus species, Escherichia coli, Klebsiella species and Citrobacter freundii cause appendicitis. Appendicitis is usually polymicrobial. The case assumes importance because of single aetiological agent i.e. unimicrobial and n...

The diagnosis of acute appendicitis is mainly based on clinical examination and various diagnostic scores are available. We compared Alvarado and RIPASA scoring systems for the diagnosis of acute appendicitis and their negative appendectomy rate in 100 patients of appendicitis.

28 Background: Appendicitis occurs with increased frequency in HIV infected compared to 29 HIV uninfected persons. CMV-related appendicitis specifically presents with typical 30 appendicitis symptoms including surgical abdomen, fever and leukocytosis and may have 31 a more severe course with higher mortality than other types of infective appendicitis. We 32 report the first case of CMV appendic...

BACKGROUND Our previous retrospective study revealed the three preoperative predictors of complicated appendicitis (perforated or gangrenous appendicitis), which are body temperature ≥37.4 °C, C-reactive protein ≥4.7 mg/dl, and fluid collection surrounding the appendix on computed tomography. We reported here an additional prospective study to verify our ability to predict complicated appendici...

BACKGROUND Appendicitis occurs with increased frequency in HIV infected compared to HIV uninfected persons. CMV-related appendicitis specifically presents with typical appendicitis symptoms including surgical abdomen, fever and leukocytosis and may have a more severe course with higher mortality than other types of infective appendicitis. We report the first case of CMV appendicitis as a manife...

BACKGROUND The role of interval appendectomy (IA) after an episode of acute appendicitis is debated. HYPOTHESIS Patients treated nonoperatively for acute appendicitis do not require routine IA. DESIGN Retrospective cohort study using discharge abstract data. SETTING Twelve regional Kaiser Permanente hospitals in Southern California. PATIENTS A total of 32 938 patients were hospitalized ...

Background: Acute appendicitis is one of the common and urgent illnesses among children.  Children usually are unable to help the physicians completely due to weakness in describing the medical history. Moreover, acute appendicitis overlaps with conditions of other diseases in terms of Symptoms and signs in the first hours of presentation. These conditions lead to unwanted biases as well as err...
