Spinal and paraspinal infections caused by Streptococcus pneumoniae remain a rare event. We present two cases from our institution, discuss the pathophysiology, and present a literature review of an additional 50 cases of spinal pneumococcal infections. Spinal epidural abscess and vertebral osteomyelitis as well as paraspinal abscesses caused by pneumococcus were included in the analysis. As has been reported for spinal infections due to other bacteria, persistent localized back pain with an elevation in inflammatory markers was almost universal. The lumbar spine was the most commonly involved. Pneumococcus was most frequently isolated from material obtained at the site of the infection; blood cultures were a less common source. The majority of patients with neurologic deficits had spinal epidural abscess or phlegmon, and had a higher mortality. Most patients were treated with 6 weeks of parenteral antimicrobials, and surgical intervention was not associated with a mortality benefit. 相似文献

Thirty-seven cases of microbiologically demonstrated pyogenic hepatic abscess were observed in a prospective study over a seven-year period. Biliary disease was the most common source of liver abscess (42%).Streptococcus milleri was the most common cause of hepatic abscess, accounting for 51% of the cases. Hepatic abscess is due toStreptococcus milleri clinically distinct from other forms of pyogenic liver abscess due to its torpid nature and the longer duration of its symptoms [42 vs. 11 days]. Occult hepatic abscess should be suspected if the blood culture is positive forStreptococcus milleri, since 28% of bacteremia cases due toStreptococcus milleri stem from hepatic abscesses. It is important to distinguishStreptococcus milleri from other members of the viridans streptococci group, which are frequently isolated as contaminants, but only exceptionally cause hepatic abscess. Unlike other pyogenic hepatic abscesses, those caused byStreptococcus milleri are frequently monomicrobial (79%). In the present study, empirical therapy of pyogenic hepatic abscess always included a drug that is effective againstStreptococcus milleri. 相似文献

Central nervous system tuberculosis is still one of the leading causes of morbidity in the developing world, and tuberculous abscess is one of its uncommon manifesting forms. It closely mimics a pyogenic abscess clinically, radiologically, and histologically. An accurate diagnosis is imperative due to therapeutic implications. In this study, 21 cases of tuberculous abscesses encountered over a period of 13 years (1995–2007) were reviewed to study the clinical, radiological, and histopathological spectrum of the disease. The presence of palisading epithelioid cells and sheets of foamy histiocytes, enclosing a neutrophillic exudate rich in fibrin with nuclear debris, were clues as to suspicion of a tuberculous abscess. The demonstration of acid fast bacilli in the wall of the abscess or necrotic contents by microscopy or culture is essential to confirm the diagnosis of tuberculous abscess. A high index of clinical suspicion is necessary particularly in countries endemic for tuberculosis to ensure an accurate diagnosis and application of an appropriate therapy. 相似文献

We describe a case of right ilio-psoas abscess caused by stump appendicitis 14 years after open appendectomy.
Stump appendicitis is a rare complication of appendectomy. Right ilio-psoas abscess was diagnosed in an immunecompetent patient and treated by ultrasound guided percutaneous drainage twice without identifying the cause of the
abscess. The patient did not improve until diagnostic laparoscopy was performed revealing a long stump appendicitis
to be the origin of infection. It was treated by completion appendectomy. Surgical exploration may be necessary in
persistent or recurrent ilio-psoas abscesses. We identified 4 reported cases of post-appendectomy ilio-psoas abscess
but without recognizing the cause of the abscess and its relation to appendectomy. This is the first reported case of
ilio-psoas abscess that developed as a complication of stump appendicitis. 相似文献

Three cases of brain abscesses due to Streptococcus MG-intermedius are reported, and the literature pertaining to this subject is reviewed. The importance of careful and complete identification of these etiological agents of infection is stressed. The clinical presentation, the origin of S. MG-intermedius producing brain abscess, and its relation to hepatic abscesses and endocarditis are discussed. 相似文献

This nationwide study aimed to provide risk estimates for a panel of infections subsequent to pyogenic liver abscesses (PLA) in Taiwan. In this study, we selected 12 050 patients diagnosed with PLA as our study cohort and 60 250 non-PLA patients as our comparison cohort. We individually tracked each subject for a 1-year period beginning with their index date to identify those who were subsequently diagnosed with any of the following infections: pneumonia, endophthalmitis, septic pulmonary embolism, pulmonary abscess, pleural empyema, meningitis, abscess of prostate, renal and perinephric abscess, epidural spinal abscess, osteomyelitis, necrotizing fasciitis, splenic abscess, psoas abscess and infectious endocarditis. We found that during the 1-year follow-up period, the subjects with PLA had a consistently higher incidence of all types of infections than comparison subjects. In particular, compared with subjects without PLA, the adjusted hazard ratios (HR) of pulmonary abscess, pleural empyema, renal and perinephric abscess, epidural spinal abscess and splenic abscess were 26.71, 18.56, 43.21, 51.32 and 126.51, respectively. We further analysed the HR of extra-hepatic Klebsiella pneumoniae infections among patients with PLA caused by K. pneumoniae. We found that the HR was higher for 12 of the 15 analysed extra-hepatic infections after restricting the analysis to only infections with K. pneumoniae aetiologies. 相似文献

A case of thyroid abscess due to Rhodococcus equi in an HIV-positive patient with previous pulmonary abscess is reported. Rhodococcus equi is a gram-positive rod that can cause infections in both immunocompetent and immunocompromised patients, though it occurs more frequently in patients with dysfunctional cellular immune systems. Several cases of Rhodococcus equi infection in persons infected with HIV have been reported. In these patients Rhodococcus equi usually invades the lungs, producing pneumonia. These infections often relapse, accompanied by intermittent bacteremia, despite conventional treatment. Extrapulmonary abscesses can occur. 相似文献

The polymicrobial nature of invasive pyogenic infections may be underestimated by routine culture practices, due to the fastidious nature of many organisms and the loss of viability during transport or from prior antibacterials. Pyrosequencing was performed on brain and liver abscesses and pleural fluid and compared to routine culture data. Forty-seven invasive pyogenic infection samples from 44 patients [6 intracerebral abscess (ICA), 21 pyogenic liver abscess (PLA), and 18 pleural fluid (PF) samples] were assayed. Pyrosequencing identified an etiologic microorganism in 100?% of samples versus 45?% by culture, p <0.01. Pyrosequencing was also more likely than traditional cultures to classify infections as polymicrobial, 91?% versus 17?%, p <0.001. The median number of genera identified by pyrosequencing compared to culture was 1 [interquartile range (IQR) 1-3] versus 0 (IQR 0-1) for ICA, 7 (IQR 1-15) versus 1 (IQR 0-1) for PLA, and 15 (IQR 9-19) versus 0 (IQR 0-1) for PF. Where organisms were cultured, they typically represented the numerically dominant species identified by pyrosequencing. Complex microbial communities are involved in invasive pyogenic infection of the lung, liver, and brain. Defining the polymicrobial nature of invasive pyogenic infections is the first step towards appreciating the clinical and diagnostic implications of these complex communities. 相似文献

We describe a patient who suffered from recurrent intraabdominal abscesses. The last two of the three abscesses were certainly caused by Salmonella paratyphi C. The time interval between the first and the second abscess was 25 years, and that between the second and the third abscess was 20 years. Single infection with this microorganism is very rare in Israel, with only four known cases in the last 20 years. The annual frequency in the United States is 0 to 2 cases per year. In recent years, this infection has also been very rare in other parts of the world. Our case is unique as it recurred two or three times. The infection was probably dormant for a very long time. During the dormant years, the patient was clinically healthy. To our knowledge a recurrent infection with this microorganism has not previously been reported in the literature. 相似文献

Oral Campylobacter species are rarely reported to cause extraoral infections. Here we present three cases of extraoral abscess caused by an oral Campylobacter sp. and a Streptococcus sp. The Campylobacter species were all isolated anaerobically and identified by sequencing analysis of the 16S rRNA gene. The cases included a breast abscess caused by Campylobacter rectus and a non-group A beta-hemolytic streptococcus in a patient with lymphoma, a liver abscess caused by Campylobacter curvus and an alpha-hemolytic streptococcus in a patient with complicated ovarian cancer, and a postobstructive bronchial abscess caused by C. curvus and group C beta-hemolytic Streptococcus constellatus in a patient with lung cancer. The abscesses were drained or resected, and the patients were treated with antibiotics with full resolution of the lesions. The C. curvus cases are likely the first reported infections by this organism, and the C. rectus case represents the second such reported extraoral infection. 相似文献

Streptococcus intermedius, included in the 'milleri group', is a commensal of the mouth and upper respiratory tract but it has often been associated with various pyogenic infections, such as endocarditis, pneumonia, abdominal or cerebral abscess, rarely with osteomyelitis, and exceptionally with muscular abscess. The first observed case of iliac osteomyelitis with gluteal muscle abscess caused by S. intermedius is reported. It is essential to recognise members of the 'milleri group' as possible agents of bone and muscle pyogenic infection because its management requires a timely diagnosis and prolonged antimicrobial treatment to achieve complete clinical and radiological recovery. 相似文献

Brain abscess is a life-threatening infection caused by spread from infected parameningeal or remote foci. Historically, streptococci have been the predominant organisms reported while brain abscess metastatic from liver abscess caused by Klebsiella pneumoniae has been a more recent emerging problem. This study retrospectively analyzed the characteristics of community-acquired brain abscess admitted during an 11-year period. There were 17 men and 7 women with age from 20 to 82 years (median, 41 years). The most common source of infection was liver abscess, followed by otitic infection and sinusitis. The classic triad of fever, headache and focal neurologic deficit was noted in only 25% of cases. Spread of the abscess to multiple lobes was common (n = 6). The most commonly identified organisms were Streptococcus spp. (n = 7) and K. pneumoniae (n = 5). All 5 cases of K. pneumoniae brain abscess also had concomitant pyogenic liver abscess and 4 of them had diabetes mellitus. In this study, brain abscess was common in young patients and in patients with diabetes mellitus. In Taiwan, Streptococcus spp. and K. pneumoniae are leading etiologies for community-acquired brain abscess. Liver abscess is the most likely source of K. pneumoniae brain abscess. 相似文献

A nosocomial pyogenic liver abscess caused by an extended-spectrum beta-lactamase-producing Klebsiella pneumoniae isolate presented in a man with adenocarcinoma of the stomach. The K. pneumoniae strain isolated from blood and liver aspirate cultures after antibiotic therapy for recurrent bacteremia was resistant to all extended-spectrum beta-lactams except imipenem and differed from K. pneumoniae strains causing community-acquired liver abscesses. 相似文献

Enterococcus hirae infection is extremely rare in humans. In this paper, we describe a case of Enterococcus hirae spondylodiscitis complicated with anterior epidural abscess and multiple psoas abscesses in a 55-year-old man with diabetes mellitus. Despite appropriate antimicrobial therapy, surgery was required. This is the first reported case of spondylodiscitis due to this microorganism. Only two other case reports of human infection by E. hirae are available in the medical literature worldwide. 相似文献

We describe a very late manifestation of pelvic abscesses after oocyte retrieval for in-vitro fertilization (IVF). In a twin pregnancy achieved after intracytoplasmic sperm injection, rupture of bilateral ovarian abscesses occurred at the end of the second trimester. An emergency laparotomy was necessary because of an acute abdomen. This complication led to severe maternal and neonatal morbidity, preterm birth and neonatal death. The rare occurrence of acute abdomen in pregnancy due to pelvic infection and the non-specific symptoms of a pelvic abscess after oocyte retrieval for IVF are discussed. 相似文献

We report a case of a brain abscess due to Bacillus macerans and Clostridium sp. following a penetrating periorbital injury by a wooden branch. Intracranial penetration by and retention of a foreign body were not suspected initially, and neurological symptoms developed only 2.5 months later. Previously reported cases of brain abscesses due to Bacillus species are reviewed. 相似文献

We developed a murine model of kidney abscess by direct renal injection of either Escherichia coli (1 x 10(6) to 7 x 10(6) organisms) or sterile medium. Bacterial infection produced renal abscesses, bacteremia, and late-onset leukocytosis in all animals. Controls were unaffected. This model may be useful for the study of various sequelae of kidney infection. 相似文献

Aspergillus nidulans is one of the several species of Aspergillus with low pathogenicity. The significant infections of A. nidulans in human have rarely been reported, almost exclusively in patients with chronic granulomatous disease (CGD). CGD is a primary immunodeficiency disease which results from the absence of the NADPH oxidase in the phagocytic cells, leading to recurrent pyogenic infection and granuloma and abscess formation. Here we report a fatal case A. nidulans infection in a six-year-old boy with chronic granulomatous disease. A. nidulans was isolated from the culture of a paraspinal abscess and Aspergillus was detected in the surgical tissue by in situ hybridization. The patient succumbed despite prolonged treatment with high-dose amphotericin B, itraconazole and interferon-alpha. To our knowledge, this is the first report of A. nidulans infection in Korea. 相似文献

We receive around 60 cases of hepatic abscess in a year. The commonest diagnosis reached at the time of discharge is amoebic liver abscess. The diagnosis of amoebic liver abscess is mostly presumptive and thus the patients are usually given a mixed treatment with injection ceftriaxone and tablet metronidazole. Here we report three cases of hepatic abscess diagnosed recently, where ascariasis was the probable etiology. Ascariasis may be a much commoner cause of hepatic abscesses in this region than we think. 相似文献

A case of meningitis and brain abscess due toHaemophilus paraphrophilus in a patient with congenital heart disease is reported. The abscess communicated with the cerebral ventricular system. Although the infecting strain was found to be highly sensitive to ampicillin, the patient died despite appropriate antimicrobial therapy. Characteristics distinguishingHaemophilus paraphrophilus and related species are discussed. 相似文献
