  • pott s puffy tumor and Epidural Abscess arising from dental sepsis a case report
    Laryngoscope, 2001
    Co-Authors: Binoy Chandy, John R Todd, Fred J Stucker, Cherieann O Nathan
    Abstract:

    Objective To present an unusual case of two uncommon cranial complications of frontal sinusitis: Pott's puffy tumor and Epidural Abscess arising from frontal sinusitis of dental origin, and also two systemic complications of sinusitis: septicemia and empyema, all occurring in an immunocompetent patient. Study Design A 21-year-old man presented with a scalp swelling and Epidural Abscess. Magnetic resonance imaging and computed tomographic scans revealed unilateral opacification of the frontal sinus and an Epidural Abscess with a direct connection to the scalp Abscess. Further history revealed that his symptoms occurred coincidentally with a tooth extraction 2 months before, and he was hospitalized soon after the tooth extraction for sepsis and a lung Abscess. Methods A combined neurosurgical and otolaryngologic approach was required to treat the sinusitis and the associated Epidural and scalp Abscess. Results Cultures returned as Streptococcus intermedius from all three sites. The patient was free of disease at the 3-month follow-up. Conclusions Odontogenic maxillary sinusitis is well documented; however, there is little reported of frontal sinusitis arising from dental disease. The prevalence of sinusitis of dental origin will be reviewed, including the microbiology of this particularly virulent organism that persisted despite earlier treatment with ampicillin. Also, the current thoughts on management of these cases will be discussed with particular reference to local therapy for sinusitis in addition to systemic treatment with antibiotics.

  • spinal Epidural Abscess due to staphylococcus aureus clinical manifestations and outcomes
    Journal of Microbiology Immunology and Infection, 2008
    Co-Authors: Wanchin Chen, Jiunling Wang, Janntay Wang, Yeechun Chen, Shanchwen Chang
    Abstract:

    Background and purpose Despite advances in diagnosis and treatment, spinal Epidural Abscess due to Staphylococcus aureus remains a challenge to clinicians. In this study, we describe the clinical features and outcomes of patients with spinal Epidural Abscess due to S. aureus. Methods Thirty one cases of spinal Epidural Abscess due to S. aureus treated at the National Taiwan University Hospital from January 2001 to December 2006 were retrospectively reviewed, using a standardized case collection form. Spinal Epidural Abscess was diagnosed by computed tomography or magnetic resonance imaging of the spine. Results The median age of subjects was 55 years (range, 20 to 90 years) and the male-to-female ratio was 4.2. All patients had spine pain and 18 (58.1%) had fever. Lumbar or lumbosacral region was the most frequently involved site of spinal Epidural Abscess (61.3%), and 83.9% of the patients also had vertebral osteomyelitis. Sixteen patients (51.6%) were treated successfully with antibiotics alone for a median duration of 70 days (range, 23 to 274 days), whereas the median duration of antibiotic therapy in patients undergoing surgical intervention was 102 days (range, 40 to 227 days). Renal failure, malignancy or underlying comorbid illness estimated by Charlson score was predictive of a poor prognosis with treatment failure or mortality. Conclusion Although medical treatment alone might benefit selected patients with spinal Epidural Abscess due to S. aureus and minimal neurologic sequelae, close monitoring of the evolution of neurologic deficits with radiographic imaging follow-up is necessary, since the rate of progression of neurologic impairment is difficult to predict.

  • candida albicans spinal Epidural Abscess secondary to prosthetic valve endocarditis
    Diagnostic Microbiology and Infectious Disease, 2001
    Co-Authors: Jader Liang, Yeechun Chen, Shanchwen Chang, Chitai Fang, Kwentay Luh
    Abstract:

    A 56-year-old woman, with underlying rheumatic heart disease status post mitral valve replacement, presented with fever, low back pain radiating to right leg, and congestive heart failure. Magnetic resonance imaging detected an L5-S1 spinal Epidural Abscess. A vegetation on prosthetic mitral valve was found by transesophageal echocardiography. Cultures of Epidural aspirate, surgical specimen, and blood all grew Candida albicans. She received surgical drainage of the spinal Epidural Abscess and i.v. amphotericin B 1 mg/kg/day for eight weeks. Clinical symptoms improved gradually and she was discharged without neurologic sequelae. She remained well and continued to lead an active life two years after discharge.
