1/4. escherichia hermannii infection of a cephalohematoma: case report, review of the literature, and description of a novel invasive pathogen.We describe a neonate with bacterial infection of a cephalohematoma by escherichia hermannii and with meningitis. We review the literature on infected cephalohematomas and E. hermannii and document the first case of invasive disease due to this pathogen.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
2/4. The characterization of bacterial and nonbacterial prostatitis by prostatic immunoglobulins.Although inflammatory diseases of most human secretory surfaces are difficult to investigate clinically, the secretory immune system of the human prostate may be studied relatively easily because prostatic fluid may be obtained from the gland by digital massage. We studied inflammatory conditions of the prostate to establish whether we could use the humoral immune response to differentiate these conditions. Using a sensitive solid-phase radioimmunoassay, we measured total IgA and IgG, and IgA and IgG antibodies to enterobacteriaceae in the serum and prostatic fluid of men with and without prostatic inflammation. These studies show that levels of IgA and IgG in the prostatic fluid of men with bacterial prostatitis are higher than those in men without histories of urinary or prostatic infections. In men with bacterial prostatitis, prostatic antibodies to enterobacteriaceae were elevated 12 to 18 months after curative treatment and indefinitely after ineffective treatment; anti-Enterobacteriaceal IgG levels returned to normal after infection only with cure. Total IgA and IgG in the prostatic fluid of men with nonbacterial prostatitis--men who have signs of prostatic inflammation without evidence of old or ongoing bacterial infection--are also higher than levels found in uninfected individuals. Although this finding supports an inflammatory etiology for the symptoms seen in nonbacterial prostatitis, no significant IgA or IgG Enterobacteriaceal antibody titers were detected in these patients. This excludes a remote Enterobacteriaceal infection as a cause of nonbacterial prostatitis. These observations confirm that the prostate gland is a distinct part of the male secretory immune system.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
3/4. The spectrum of myositis and rhabdomyolysis associated with bacterial infection.OBJECTIVE. (1) To describe the clinical and radiographic features of 6 patients with myositis or rhabdomyolysis associated with bacterial infection. (2) To analyze the role of computed tomography (CT) in myositis associated with bacterial infection. methods. review of cases treated by the authors with literature review. RESULTS. Two patients had classical pyomyositis with staphylococcus aureus as the etiologic agent. One patient had pyomyositis with enterobacter cloacae (the first reported to our knowledge), 2 had myositis/fasciitis (one due to clostridium perfringens and one due to S. aureus), and one had fatal toxic rhabdomyolysis in association with C. perfringens bacteremia without evidence of gas gangrene. No patient had a completely normal CT scan of affected muscles, but CT scans in 3 patients failed to show abscesses that were subsequently discovered at surgery, while in another patient CT scanning falsely suggested a large abscess that was not present at surgery. CONCLUSION. Infection associated muscle involvement represents a spectrum of clinical manifestations that include pyomyositis, myonecrosis, fasciitis/myositis, and toxic rhabdomyolysis. diagnosis may be delayed by the often mild clinical presentation. CT scanning alone may be unreliable in distinguishing muscle abscess from swollen muscle unless combined with CT guided needle biopsy.- - - - - - - - - - ranking = 6keywords = bacterial infection (Clic here for more details about this article) |
4/4. Relapsing Henoch-Schonlein purpura associated with a tubo-ovarian abscess due to morganella morganii.Henoch-Schonlein purpura is the most common vasculitis in children. It is frequently preceded by either viral or bacterial infections of the upper respiratory tract. We present a 15-year-old female who developed recurrent episodes of Henoch-Schonlein purpura. Eventual investigation of the patient's abdominal pain, initially attributed to vasculitis involving the gastrointestinal tract, revealed a left tubo-ovarian abscess caused by morganella morganii. Salpingo-oophorectomy resulted in complete remission of the disease process.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
