Little epidemiological research is available on the relationship between splenectomy and renal and perinephric abscesses. The purpose of the study was to examine this issue in Taiwan.We conducted a population-based retrospective cohort study using the hospitalization dataset of the Taiwan National Health Insurance Program. A total of 16,426 participants aged 20 and older who were newly diagnose...

OBJECTIVE To clarify presentations, organisms, and locations of deep neck abscesses in children. DESIGN Retrospective review. SETTING Tertiary children's hospital. The study population comprised 169 patients younger than 19 years who were surgically treated for deep neck abscesses between 1989 and 1999. MAIN OUTCOME MEASURE Resolution of abscess. RESULTS Neck mass (91%), fever (86%), ce...

Secondary infections as a result of tail biting cause substantial economic losses in pig production and are a subject of concern for animal welfare. The use of first-choice antibacterial agents in the treatment of tail biting in finishing pigs is hypothesized to be negatively correlated with the development of systemic infection. This would be expected to reduce the prevalence of post-mortem py...

Hyperbaric oxygen exposures were evaluated for treatment of progressive liver abscesses produced by intraperitoneal injection of combined cultures of Fusobacterium necrophorum plus either Bacteroides fragilis subsp. fragilis or Fusobacterium nucleatum in a mouse model. Infected control and hyperbaric oxygen-exposed mice were autopsied 5 or 6 weeks after inoculation of bacteria and were assigned...

The usual treatment of bacterial abscesses, except lung or tubo-ovarian abscesses, includes therapeutic drainage. Increasing evidence suggests that some abscesses respond to antimicrobial therapy without drainage. To study this issue, a MEDLINE search of the literature (1966-1994) was performed for cases of bacterial abscess in which treatment without definitive drainage was attempted. Four hun...

In nine consecutive patients with otogenic cerebral abscesses a mixed growth of aerobic and obligate anaerobic bacteria was isolated from the pus in five patients, and in the remaining four obligate anaerobes were the sole isolates. The commonest obligate anaerobe isolated was Bacteroides fragilis, which was present in all but one patient. The patients were all treated with metronidazole for th...

Animal models of liver abscess formation with Entamoeba histolytica suggest that the neutrophil is the first cell of the host immune system to interact with the invading ameba. In vitro studies have suggested that lysis of neutrophils by virulent amebae may exacerbate the damage seen in amebic liver abscesses. To investigate the role of neutrophils in vivo, we used the severe combined immunodef...

BACKGROUND Splenic abscesses in children are rare. In recent years aseptic abscesses have been recognized as a new disease entity, especially in adults. CASE PRESENTATION We present a rare case of a 15 year old girl with aseptic abscesses, in whom antibiotic therapy comprising metronidazole and meropenem was partly beneficial in improving the patient's clinical condition and inflammatory para...

AIM To evaluate whether crypt abscesses from inflammatory bowel disease (IBD) patients contain bacteria and to establish their nature. METHODS We studied 17 ulcerative colitis patients, 11 Crohn's disease patients, 7 patients with acute self-limited colitis (ASLC) and normal colonic biopsies from 5 subjects who underwent colonoscopy for colon cancer screening. A fluorescent in situ hybridizat...

BACKGROUND AND PURPOSE The relationship between prosthetic hip infection and a psoas abscess is poorly documented. We determined the frequency of prosthetic hip infections associated with psoas abscesses and identified their determinants. METHODS We conducted a 2-year observational study. Data from patients with psoas abscesses that were associated with prosthetic hip infections were examined...
