Acute abdominal pain and fever or suspected abdominal abscess.
A variety of clinical presentations occur in patients with acute abdominal pain accompanied by fever. This review concentrates on the evaluation of patients with acute diffuse abdominal pain, human immunodeficiency virus (HIV)-positive patients with acute abdominal pain and patients with suspected abdominal Abscess. Other Appropriateness Criteria® topics address acute right upper quadrant pain, acute right lower quadrant pain, and acute left lower quadrant pain. Imaging evaluation varies slightly among patients with different clinical presentations. In general, CT is the most important modality in evaluating patients with abdominal pain, more so in those with fever. Two reports have found CT superior to clinical evaluation for finding the cause of abdominal pain. CT was correct in 90%-95% of cases, while clinical evaluation was correct in 60%-76% of cases. Additionally, the use of CT in patients with acute abdominal pain increases the emergency department clinician's level of certainty and reduces hospital admissions by 24%. The presence of a white blood count (WBC) >11.5 has been correlated with a positive abdominal CT, and the combination of WBC >11.5, male sex, and age less than 25 years has been shown to correlate with a diagnosis of appendicitis. Abdominal CT without the use of oral or intravenous (IV) contrast has been advocated as an alternative to abdominal radiographs for evaluating appendicitis; however, the use of contrast agents greatly increases the spectrum of detectable pathology.

Surgery consists of opening and draining the Abscess. Laboratory tests are often done to examine the fluid. This can help identify the infection-causing organism so that more appropriate antibiotics or anti-fungals can be prescribed. The specific surgical procedure depends on the size and depth of the Abscess. The entire Abscess may be removed (excised) if it is near the surface and enclosed in a sac.
Note: Innate Immunity to Amebic Liver Abscess Is Dependent on Gamma Interferon and Nitric Oxide in a Murine Model of Disease
Previous studies in our laboratory showed that SCID mice were more susceptible to amebic liver Abscess than the congenic C.B-17 strain ( 2 ). We hypothesized that if IFN- plays a role in innate immunity against amebic liver Abscess, it would be detectable in SCID mice. Therefore, we bred IFN- receptor knockout mice on the 129/ Sv/ Ev C57BL/ 6 background with C.B-17 SCID animals and intercrossed the resulting double heterozygotes and screened them for homozygosity at both loci. These double-knockout animals (SCID and IFN- receptor negative) were subsequently backcrossed onto the C.B-17 SCID background for 6 generations, resulting in animals that theoretically should have 98 of the C.B-17 genome. In two separate experiments, groups of five C.B-17 SCID mice and groups of five C.B-17 SCID mice with targeted disruption of the IFN- receptor -chain gene underwent intrahepatic challenge with 10 6 HM1:IMSS amebic trophozoites. The histologic appearance of liver abscesses in C.B-17 SCID mice homozygous for the disruption of the gene encoding the IFN- receptor chain did not differ from that seen in C.B-17 SCID mice ( 2 ). However, we found that C.B-17 SCID mice homozygous for the disruption of the gene encoding the IFN- receptor chain had developed significantly larger amebic liver abscesses at 48 h following infection than C.B-17 SCID mice (Table 1 ). These data suggest that IFN- plays a role in innate immunity to amebic liver Abscess in SCID mice. We have previously shown that neutrophils are important for containment of amebic liver abscesses in SCID mice. IFN- may provide protection against amebic liver Abscess in SCID mice by activating neutrophils and/ or macrophages for amebicidal activity.
Definition of abscess - NCI Dictionary of Cancer Terms
An enclosed collection of pus in tissues, organs, or confined spaces in the body. An Abscess is a sign of infection and is usually swollen and inflamed.
Abscess
Abscess: A pocket of pus that
forms as the body's defenses attempt to wall off infection-causing
germs.
Abscesses
Abscesses that develop as a result of introduction of the normal endogenous flora into a normally sterile body site are often polymicrobial in nature. These flora can gain access to the sterile site by direct extension or secondary to laceration or perforation. Because of the uniqueness of the normal endogenous flora at the various body sites, the microbiology of such abscesses is generally predictable. This chapter describes the specific microbiology of polymicrobial abscesses that occur at various body sites. It also reviews the data that demonstrate the synergy between the aerobic and anaerobic components of these abscesses, and highlights the role of the bacterial capsule as a virulence factor that enhances the formation of an Abscess.

Mycotic Brain Abscess | CDC EID
To the Editor: A 38-year-old, HIV-seropositive Nigerian man sought treatment with an 8-month history of severe parietal headache, impaired memory, fatigue, paresthesia of the left arm, and left-sided focal seizures. He had no history of neurologic disorders, including epilepsy. On physical examination, the patient appeared well, alert, and oriented, with slurred speech. Evaluation of the visual fields showed left homonymous hemianopsia. All other neurologic assessments were unremarkable. The patient had a blood pressure of 120/ 80, a pulse of 88 beats per minute, and a body temperature of 37.3°C. Leukocyte count was 8,600/ µL, total lymphocyte count was 1,981/ µL, CD4+ cell count was 102/ µL, and CD4/ CD8 ratio was 0.07. HIV RNA-load was <50 copies/ mL; all other laboratory parameters were normal. The patient had received antiretroviral therapy (stavudine, lamivudine, nevirapine) for 5 months before admission, but no prophylaxis for opportunistic infections. Magnetic resonance imaging (MRI) of the brain disclosed 2 masses, 3.3 and 4.8 cm in diameter, respectively ( Figure A ), and signs of chronic sinusitis. A computed tomographic chest scan showed infiltration of both lower segments with multiple, small nodules ( Figure B ). Blood cultures were repeatedly negative. A computer-guided needle-aspiration of the brain lesions yielded yellow-brown, creamy fluid in which abundant septated fungal hyphae were detected microscopically ( Figure C ). Cytologic investigation was consistent with a necrotic Abscess. The cycloheximide-resistant isolate was strongly keratinolytic and identified as a Chrysosporium anamorph of Nannizziopsis vriesii ( 1,2 ). High-dose antimicrobial treatment with voriconazole (200 mg twice daily, subsequently reduce

Medical Encyclopedia: Abscess
Abscesses occur when an area of tissue becomes infected and the body's immune system tries to fight it. White blood cells move through the walls of the blood vessels into the area of the infection and collect within the damaged tissue. During this process, pus forms. Pus is the build up of fluid, living and dead white blood cells, dead tissue, and bacteria or other foreign substances.

15. The Respondent revised and resubmitted his claim to WPS for the post-operative examination and procedures performed at the initial post-operative visit on 10/ 16/ 02 on claim forms dated 8/ 7/ 03, 8/ 13/ 03, 9/ 9/ 03 and 9/ 24/ 03. On the revised and resubmitted claim forms dated 8/ 7/ 03, 8/ 13/ 03 and 9/ 9/ 03 for services rendered on 10/ 16/ 02, Respondent continued to bill $350.00 for incision and drainage of an Abscess on the patient s right hallux. The Respondent knew or should have recognized at the time he revised and resubmitted the claim forms dated 8/ 7/ 03, 8/ 13/ 03 and 9/ 9/ 03 that this claim for incision and drainage of an Abscess on the patient s right hallux was false. When the Respondent revised and resubmitted his claim to WPS for the post-operative examination and procedures performed at the initial post-operative visit on 10/ 16/ 02 on the claim form dated 9/ 24/ 03, he increased the amount of the bill to $495.00 and changed the procedure billed for from the incision and drainage of an Abscess to debridement of the skin, full thickness.

DISPOSITION SUMMARY
DNR - Abscesses
Abscesses are circumscribed collections of purulent material (pus) found in several species of animals in a variety of locations. This purulent inflammation is usually caused by one of four pyogenic (pus producing) bacteria: Corynebacterium, Pseudomonas, Streptococcus and Staphylococcus . Abscesses formed in mammals generally contain white, green or yellow creamy material whereas, because of the high body temperature of birds, their abscesses generally have a caseous (cheesy) exudate, are walled-off and are painless. An Abscess may be acute or chronic, focal or multiple, and may range in size from microscopic to unlimited dimensions. An Abscess occurring on the footpads of avian species is called bumblefoot.
The Role of Bacterial Capsule in the Development of Endophthalmitis from Liver Abscess Patients: a Neutrophil Phagocytosis Model of Klebsiella pneumoniae.
BACKGROUND: K. pneumoniae (K.P.) has been well documented as the most prevalent causative agent of bacterial liver Abscess especially in the Asian Pacific region. To better understand the role of serotype K1 or K2 in the development of endophthalmitis from liver Abscess, the resistance to neutrophil phagocytosis of K.P. with different capsular polysaccharides (CPS) isolated from liver Abscess (L.A.) and non-L.A. patients were compared. METHODS: A total of 70 K.P. isolates including serotype K1 (23)/ K2 (10) and non-K1/ K2 (37) were evaluated in this study. Acapsular mutant which was derived from capsular serotype K1 isolate was also included. Phagocytosis was measured by flow cytometry, fluorescence microscopy, and bioassay. RESULTS: K1/ K2 isolates were significantly more resistant (P

CDC - Primary Liver Abscess Caused by One Clone of Klebsiella pneumoniae with Two Colonial Morphotypes and Resistotypes
A 42-year-old man (patient A) was admitted on July 31, 2000, for a fever of 2 weeks duration. He had had diabetes mellitus for 20 years and alcoholism for >10 years. Physical examination and abdominal echography showed hepatomegaly and a huge Abscess (12 cm x 10 cm x 8 cm) over the right lobe of the liver. Laboratory tests showed leukocytosis (14,600/ L) with a left shift. After blood cultures, ceftriaxone (2 g every 12 hours) was given. A pigtail catheter was inserted for continuous drainage on the 5th hospital day. Abscess aspirate culture yielded K. pneumoniae with two colonial morphotypes (isolates on trypticase soy agar plates supplemented with 5% sheep blood [BBL Microbiology Systems, Cockeysville, MD] after 24 hours of incubation in ambient air) ( Figure 1 ) and two resistotypes (by the routine disk diffusion method). One (isolate A1) had mucoid, opaque colonies and was resistant to ampicillin but susceptible to cefazolin and cefoxitin, and the other (isolate A2) had nonmucoid, white colonies and was resistant to ampicillin, cefazolin, and cefoxitin. Both isolates were susceptible to amoxicillin-clavulanate and cefotaxime. Blood cultures were negative. Because of persistent fever, the antibiotic was changed to imipenem (500 mg every 6 hours) on the 11th hospital day. Fever subsided 3 days after imipenem administration was begun. Imipenem was continued for a total of 24 days, followed by ciprofloxacin (750 mg every 12 hours) for 3 weeks. A follow-up echography 4 months after antibiotic treatment ended showed that the Abscess had disappeared.
