    Pyogenic liver abscess is a rare entity, but it is fatal when untreated. With a peak incidence in the fifth decade of life, its early recognition and intervention are key to successful treatment and better prognosis of patients. In recent years, its approach has been enhanced by the use of percutaneous drainage, improved imaging techniques and a better microbiological characterisation, allowing for a more appropriate use of antibiotics. Clinical manifestations are variable and depend on the size of the abscess, the condition of the patient, associated diseases and possible complications. Among the most common symptoms that stand out are the pain in the upper quadrants of the abdomen, high fever, nausea and vomiting. The authors present the case of a patient who developed an atrial flutter as the initial presentation of a hepatic abscess that imagiologically mimicked a hepatic tumour. PMID:27170608

    AIM: To define optimum management of the pyogenic liver abscess and assess new trends in treatment. METHODS: One hundred and sixty nine patients with pyogenic liver abscess managed at Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir (India) from July 2001 to August 2006 were studied to evaluate and define the optimum treatment. RESULTS: Mortality in the surgically treated group of patients was 9.4% (12/119), while those treated non-surgically had a fatality rate of 16.66% (7/42). Multiple liver abscesses treated surgically had a surprisingly low mortality of 30%. The biliary tract (64.97%) was the most common cause of liver abscess. Multiple abscesses, mixed organisms and abscess complications are all associated with a significantly increased mortality. However, the lethality of the primary disease process was the most important factor in determining survival. CONCLUSION: Transperitoneal surgical drainage and antibiotics are the mainstay of treatment. Percutaneous drainage is recommended for high risk patients only. PMID:21206721

    Abstract Little is known on the association between appendectomy and pyogenic liver abscess. The objective of this study was to investigate the association between appendectomy and the risk of pyogenic liver abscess in Taiwan. This population-based retrospective cohort study was conducted using the hospitalization dataset of the Taiwan National Health Insurance Program. There were 212,530 subjects age 20 to 84 years with newly diagnosed appendectomy as the appendectomy group since 1998 to 2010, and 850,099 randomly selected subjects without appendectomy as the nonappendectomy group. Both appendectomy and nonappendectomy groups were matched with sex, age, comorbidities, and index year of diagnosing appendectomy. The incidence of pyogenic liver abscess at the end of 2011 was estimated in both groups. The multivariable Cox proportional hazards regression model was applied to investigate the hazard ratio (HR) and 95% confidence interval (CI) for risk of pyogenic liver abscess associated with appendectomy and other comorbidities including alcoholism, biliary stone, chronic kidney disease, chronic liver diseases, and diabetes mellitus. The overall incidence of pyogenic liver abscess was 1.73-fold greater in the appendectomy group than that in the nonappendectomy group (3.85 vs 2.22 per 10,000 person-years, 95% CI 1.71, 1.76). The multivariable regression analysis disclosed that the adjusted HR of pyogenic liver abscess was 1.77 for the appendectomy group (95% CI 1.59, 1.97), when compared with the nonappendectomy group. Appendectomy is associated with increased hazard of pyogenic liver abscess. Further studies remain necessary to confirm our findings. PMID:27368018

    Liver abscess is a common pathology in the Indian subcontinent and usually results from amoebic or bacterial infection. Pyogenic abscesses usually occur in those with underlying predisposing factors like intra-abdominal infections, biliary infections or comorbidities like malignancy, immunosuppression, diabetes mellitus and previous biliary surgery or interventional endoscopy. Citrobacter is an unusual cause of pyogenic liver abscess and may occur in the setting of underlying comorbidities. We report a 56-year-old man with diabetes (operated for periampullary carcinoma 20 years ago), who presented with a history of fever for 1 week and on evaluation was found to have Citrobacter koseri-related hepatic abscess. The patient was managed with parenteral antibiotics, repeated aspiration of liver abscess and pigtail drainage. PMID:23505286

    Even though Gemella morbillorum infection (GMI) is rare in humans, it may nevertheless, cause endocarditis, meningitis, brain abscess, pleural empyema, nephritis, mediastinitis, and occasionally, liver abscess. We are describing the case of a 64-years-old Caucasian male admitted with fever and abdominal pain. Laboratory parameters revealed inflammation signs, and instrumental examinations showed the presence of diverticula in the ascending colon. Abdominal ultrasound (US) and computer tomography (CT) showed two focal lesions in the right liver lobe. One had the characteristics of a simple cyst; the second was hypoechoic with a low density area, possibly containing necrotic material. US-guided needle biopsy was found negative for neoplastic cells, showing purulent infiltrate. Pus culture was found positive for GMI. Systemic antibiotic therapy coupled with repeated US-guided needle aspiration, induced the resolution of the hepatic abscess. Few cases have been reported of hepatic abscess caused by GMI in immunocompetent non-cirrhotic subjects. PMID:25100894

    Pyogenic liver abscesses are rare with an incidence of 0.5% to 0.8% and are mostly due to hepatobiliary causes (40% to 60%). Most are polymicrobial with less than 10% being caused by Staphylococcus aureus. Of these, few are caused by methicillin-resistant Staphylococcus aureus (MRSA) and fewer still by a community-acquired strain. Here we present a case study of a patient with a community-acquired MRSA liver abscess. The patient presented with fever since 1 month and tender hepatomegaly. Blood tests revealed elevated levels of alkaline phosphatase, C-reactive protein, erythrocyte sedimentation rate, and neutrophilic leukocytosis. Blood cultures were sterile. Ultrasound of the abdomen showed multiple abscesses, from which pus was drained and MRSA isolated. Computed tomography of the abdomen did not show any source of infection, and an amebic serology was negative. The patient was started on vancomycin for 2 weeks, following which he became afebrile and was discharged on oral linezolid for 4 more weeks. Normally a liver abscess is treated empirically with ceftriaxone for pyogenic liver abscess and metronidazole for amebic liver abscess. However, if the patient has risk factors for a Staphylococcal infection, it is imperative that antibiotics covering gram-positive organisms be added while waiting for culture reports. PMID:27540556

    The pyogenic liver abscess caused by Clostridium perfringens (C. perfringens) is a rare but rapidly fatal infection. The main virulence factor of this pathogen is its α-toxin (lecithinase), which decomposes the phospholipid in cell membranes leading to cell lysis. Once the bacteria are in blood stream, massive intravascular hemolysis occurs. This can present as anemia on admission with evidence of hemolysis as indicated by low serum haptoglobin, high serum lactate dehydrogenase (LDH), elevated indirect bilirubin, and spherocytosis. The clinical course of C. perfringens septicemia is marked by rapidly deteriorating course with a mortality rate ranging from 70 to 100%. The very rapid clinical course makes it difficult to diagnose on time, and most cases are diagnosed at autopsy. Therefore it is important to consider C. perfringens infection in any severely ill patient with fever and evidence of hemolysis. We present a case of seventy-seven-year-old male with septic shock secondary to pyogenic liver abscess with a brief review of existing literature on C. perfringens. PMID:26090240

    Several recent studies have demonstrated that virulence in Entamoeba histolytica is triggered in the presence of both pathogenic and nonpathogenic bacteria species using in vitro and in vivo experimental animal models. In this study, we examined samples aspirated from abscess material obtained from patients who were clinically diagnosed with amebic liver abscess (ALA) or pyogenic liver abscess (PLA). To determine the diversity of bacterial species in the abscesses, we performed partial 16S rRNA gene sequencing. In addition, the E. histolytica and Entamoeba dispar species were genotyped using tRNA-linked short tandem repeats as specific molecular markers. The association between clinical data and bacterial and parasite genotypes were examined through a correspondence analysis. The results showed the presence of numerous bacterial groups. These taxonomic groups constitute common members of the gut microbiota, although all of the detected bacterial species have a close phylogenetic relationship with bacterial pathogens. Furthermore, some patients clinically diagnosed with PLA and ALA were coinfected with E. dispar or E. histolytica, which suggests that the virulence of these parasites increased in the presence of bacteria. However, no specific bacterial groups were associated with this effect. Together, our results suggest a nonspecific mechanism of virulence modulation by bacteria in Entamoeba. PMID:26572872

    The purpose of this study was to explore the association between zolpidem use and pyogenic liver abscess in Taiwan.This was a population-based case-control study using the database of the Taiwan National Health Insurance Program since 2000 to 2011. We identified 1325 patients aged 20 to 84 years with the first-attack of pyogenic liver abscess as the cases, and 5082 patients without pyogenic liver abscess matched with sex, age, comorbidities, and index year of hospitalization for pyogenic liver abscess as the controls. Patients whose last remaining 1 tablet for zolpidem was noted ≤7 days before the date of admission for pyogenic liver abscess were defined as current use of zolpidem. Patients whose last remaining 1 tablet for zolpidem was noted >7 days before the date of admission for pyogenic liver abscess were defined as late use of zolpidem. Patients who never received 1 prescription for zolpidem were defined as never use of zolpidem. A multivariable unconditional logistic regression model was used to measure the odds ratio (OR) and 95% confidence interval (CI) to explore the association between zolpidem use and pyogenic liver abscess.After adjustment for possible confounding variables, the adjusted OR of pyogenic liver abscess was 3.89 for patients with current use of zolpidem (95% CI 2.89, 5.23), when compared with those with never use of zolpidem. The adjusted OR decreased to 0.85 for those with late use of zolpidem (95% CI 0.70, 1.03), but without statistical significance.Current use of zolpidem is associated with the increased risk of pyogenic liver abscess. Physicians should take the risk of pyogenic liver abscess into account when prescribing zolpidem. PMID:26266369

    A 21-year-old male with no significant past medical history, presented with right upper quadrant (RUQ) abdominal pain along with fevers and chills. Lab work revealed leukocytosis, anemia, and slightly elevated alkaline phosphatase. Viral serology for hepatitis B virus, hepatitis C virus, and human immunodeficiency virus were negative and he was immunocompetent. Computed tomography imaging revealed hepatic abscesses, the largest measuring 9.5 cm. Empiric antibiotics were started and percutaneous drains were placed in the abscesses. Anaerobic cultures from the abscesses grew Fusobacterium nucleatum. This is a gram negative anaerobic bacteria; a normal flora of the oral cavity. Fusobacterium is most commonly seen in Lemiere's disease, which is translocation of oral bacteria to the internal jugular vein causing a thrombophlebitis and subsequent spread of abscesses. Our patient did not have Lemiere's, and is the first case described of fusobacterium pyogenic liver abscess in a young immunocompetent male with good oral hygiene. This case was complicated by sepsis, empyema, and subsequent abscesses located outside the liver. These abscesses' have the propensity to flare abruptly and can be fatal. This case not only illustrates fusobacterium as a rare entity for pyogenic liver abscess, but also the need for urgent diagnosis and treatment. It is incumbent on physicians to diagnose and drain any suspicious hepatic lesions. While uncommon, such infections may develop without any overt source and can progress rapidly. Prompt drainage with antibiotic therapy remains the cornerstone of therapy. PMID:25834342

The objective of this study was to investigate the association between appendectomy and the risk of pyogenic liver abscess in Taiwan.This population-based retrospective cohort study was conducted using the hospitalization dataset of the Taiwan National Health Insurance Program. There were 212,530 subjects age 20 to 84 years with newly diagnosed appendectomy as the appendectomy group since 1998 to 2010, and 850,099 randomly selected subjects without appendectomy as the nonappendectomy group. Both appendectomy and nonappendectomy groups were matched with sex, age, comorbidities, and index year of diagnosing appendectomy. The incidence of pyogenic liver abscess at the end of 2011 was estimated in both groups. The multivariable Cox proportional hazards regression model was applied to investigate the hazard ratio (HR) and 95% confidence interval (CI) for risk of pyogenic liver abscess associated with appendectomy and other comorbidities including alcoholism, biliary stone, chronic kidney disease, chronic liver diseases, and diabetes mellitus.The overall incidence of pyogenic liver abscess was 1.73-fold greater in the appendectomy group than that in the nonappendectomy group (3.85 vs 2.22 per 10,000 person-years, 95% CI 1.71, 1.76). The multivariable regression analysis disclosed that the adjusted HR of pyogenic liver abscess was 1.77 for the appendectomy group (95% CI 1.59, 1.97), when compared with the nonappendectomy group.Appendectomy is associated with increased hazard of pyogenic liver abscess. Further studies remain necessary to confirm our findings. PMID:27368018

    An unexplained increase in the frequency of pyogenic liver abscesses of unknown etiology has, fourtunately, been paralleled by significant advances in diagnostic and therapeutic methods. This report reviews experience with 14 patients operated upon at NYU Medical Center since 1971. Eight cases (57%) were cryptogenic. Other abscesses were associated with biliary disease (3); abdominal sepsis (2); and trauma (1). Abscesses were present on hospitalization in 12 patients. Clinical findings included fever (101-108 F); 100%; leucocytosis, 71%; anorexia and vomiting, 50%; localized tenderness and hepatomegaly, 50%; hypoalbuminemia, 86%; hypocholesterolemia, 78%; elevated SGOT, 71%; and elevated aikaline phosphatase, 43%. Technetium hepatic scintiscans showed focal defects in 10 of 12 patients (83%), but did not detect multiple abscesses in 2 of these. Hepatic arteriography performed in 10 patients was highly accurate, outlining single abscesses in 6 and multiple abscesses in 4. Furthermore, in one patient a false positive scintiscan was demonstrated by negative arteriography, confirmed by autopsy. In 4 patients, arteriography indicated an abscess in the posterior-superior area of the right hepatic lobe. With precise anatomical localization, a trans-thoracic approach permitted uncomplicated drainage in each case. This approach provides excellent exposure and direct drainage for abscesses in this area. An additional therapeutic adjunct in two patients, with 4 and 11 abscesses each, was postoperative intraportal infusion of antibiotics through the umbilical vein. Thirteen patients (83%) recovered, one dying from pulmonary embolism. Primary hepatic abscesses occur with increasing frequency. Primary hepatic abscesses occur with increasing frequency. Primary hepatic abscesses occur with increasing frequency. The methods described allow more precise preoperative diagnosis and direct surgical drainage. Images Fig. 1. Fig. 2. PMID:1130869

    Background/Aims Although pyogenic liver abscesses (PLAs) can be successfully treated, the visual prognosis of patients with endogenous endophthalmitis (EE) associated with a PLA is poor. Early diagnosis and prompt intervention may salvage useful vision. Therefore, we investigated risk factors for EE in patients with PLA, to facilitate early diagnosis. Methods Data from 626 patients diagnosed with PLA between January 2004 and July 2013 were analyzed retrospectively. Patients were divided into two groups: those with liver abscess-associated endogenous endophthalmitis (LAEE) and non-LAEE. Results The prevalence of EE in PLA patients was 1.92%. The mean age for all patients (373 males, 59.6%) was 62.8 years. Upon multivariate logistic regression, a liver abscess or another systemic infection (odds ratio [OR], 5.52; p = 0.005), an abscess in the right superior segment (OR, 5.26; p = 0.035), and Klebsiella pneumoniae infection (OR, 3.68; p = 0.039), were risk factors for LAEE. The final visual outcomes of patients with LAEE included no light perception in seven, hand motion only in three, and decreased visual acuity in two. Vitrectomy and early intravitreal injections of antibiotics improved visual acuity and preserved useful vision. Conclusions PLA patients with other systemic infections, abscesses in the right superior segment, and K. pneumoniae infection require close monitoring and early intervention to treat LAEE. Intravitreal antibiotic injections or early vitrectomy may salvage useful vision. PMID:26161011

    Context: Pyogenic liver abscesses (PLAs) are the most common form of liver abscesses in the United States. Most cases are caused by enteric bacteria and anaerobes. We report a case of PLA caused by a rare pathogen, Fusobacterium nucleatum, from an unusual primary site of infection. Case Report: A 60-year-old male presented with subacute fever. Initial work-up revealed leukocytosis and elevated alkaline phosphatase (ALP). Dental examination and Panorex x-ray were normal. Imaging of the liver with abdominal computed tomography demonstrated a 5.5 cm abscess in the right lobe of the liver. Culture of the aspirate grew Fusobacterium nucleatum. He improved with abscess drainage and antibiotic therapy with moxifloxacin and metronidazole. Colonoscopy performed a few weeks later, demonstrated sigmoid ulceration most likely from the previous diverticulitis. Conclusion: PLAs can be a complication of sigmoid diverticulitis and as a result of occult dental disease as well. The clinical presentation of Fusobacterium infection is diverse and can be fatal if diagnosis is delayed. Therefore, early diagnosis and treatment are the keys to preventing serious complications.

    Forty-one consecutive cases of liver abscesses seen at the National University Hospital, Singapore from 1988 to 1994 were reviewed. Twenty-seven cases (65%) were pyogenic, six (15%) amoebic, two (5%) tuberculous and six (15%) indeterminate. The predominance of pyogenic abscesses is in marked contrast to previous studies from the region a decade ago in which amoebic abscesses were the commonest type. The commonest pathogen causing pyogenic abscess was Klebsiella pneumoniae. Two cases were due to Mycobacterium tuberculosis, and this organism needs to be actively looked for in smears and cultures of aspirated material. As the majority of organisms isolated were resistant to ampicillin, empirical antibiotic treatment for suspected pyogenic abscess should include gentamicin or a cephalosporin. Percutaneous needle aspiration of the abscess was performed for 85% of pyogenic abscesses and surgery was necessary in only two cases because of complications. We found that percutaneous aspiration of liver abscess is helpful to confirm the diagnosis, provides a better bacteriological culture yield, gives a good outcome, and may uncover clinically unsuspected conditions like malignancy and tuberculoma which may mimic the presentation of liver abscesses. We recommend routine cytological examination of aspirated abscess material as well as stains and cultures for acid-fast bacilli. PMID:9122104

    In the Ga-67 scintigram, most pyogenic liver abscesses appear to be areas of high radiotracer concentration; rarely photon-deficient lesions may also occur. We present a 58-year-old man with sepsis and hepatic abscess, demonstrated by a Tc-99m BIDA study and a computerized tomogram of the body, showing homogenous radiogallium uptake throughout the liver in the Ga-67 images. To avoid missing such a ''warm'' lesion, it is emphasized that abdominal Ga-67 scintigrams for localization of a focal inflammatory lesion should be done along with Tc-99m sulfur colloid or Tc-99m BIDA scintigraphy.

    Pyogenic liver abscess (PLA) is a potentially life-threatening disease, and early diagnosis may be difficult. In order to provide diagnostic clues and to enhance the prompt management of such cases, we retrospectively investigated the clinical characteristics of PLA during a 3-year period in a tertiary-care hospital. The crude incidence rate of PLA in our study was 446.1 per 100,000 hospital admissions. Male predominance and a mean age of 57.6 +/- 14.4 years were observed. Diabetes mellitus was the most common concomitant disease, and biliary pathologies were the most common predisposing cause of this type of abscess. The most common clinical features were fever, chills, and abdominal pain. Leukocytosis was found in 67.3% of the patients, and the observed C-reactive protein (CRP) values were high. The most common pathogen was Klebsiella pneumoniae. The mortality rate was 6.5%. A complete history, physical examination, evaluation of the white blood cell count and CRP, and the prompt arrangement of imaging studies may lead to an earlier diagnosis. The aggressive performance of image-guided catheter drainage and the appropriate administration of antibiotics may reduce the mortality rate of PLA. PMID:16377869

    Knowledge of etiology and timely treatment of underlying causes, when possible, play an important role in the successful therapy of patients with pyogenic liver abscess (PLA). Recent publications from Central Europe and Southeast Asia hint at considerable differences in etiology. In this article, we aim to elaborate these differences and their therapeutic implications. Apart from some special types of PLA that are comparable in Southeast Asia and Central Europe (such as posttraumatic or postprocedural PLA), there are clear differences in the microbiological spectrum, which implies different risk factors and disease courses. Klebsiella pneumoniae (K. pneumoniae) PLA is predominantly seen in Southeast Asia, whereas, in Central Europe, PLA is typically caused by Escherichia coli, Streptococcus or Staphylococcus, and these patients are more likely to be older and to have a biliary abnormality or malignancy. K. pneumoniae patients are more likely to have diabetes mellitus. Control of septic spread is crucial in K. pneumoniae patients, whereas treatment of the underlying diseases is decisive in many Central European PLA patients. PMID:20503444

    An 18-year-old, previously healthy man admitted with abdominal pain, high-grade fevers, nausea and emesis was found to have multiple hepatic abscesses. Aspiration cultures grew Fusobacterium necrophorum, a rare bacterium causing potentially fatal liver abscesses in humans. Following sequential percutaneous drainages and narrowing of antibiotics, the patient was discharged on a 6-week antibiotic course and showed no signs of infection. A week after presentation it was discovered that he had experienced upper respiratory symptoms and sore throat prior to presentation. Because oropharyngeal infections are a potential source of bacteremia, they must be considered in the differential diagnosis of patients presenting with hepatic abscesses and no evidence of immunocompromise.

    During a six-year period, eleven persons with primary pyogenic abscess of the psoas muscle were treated at the Mackay Memorial Hospital. Five were males and six were females and their average age was 47.2 years (range 6-83 years). The abscess was identified by CT in 7 patients, MRI in 2 and ultrasonography in 1. One abscess was found during laparotomy. Treatment included extraperitoneal drainage of the abscess in 7 patients and CT guided aspiration in 3. One patient improved after antibiotic therapy and they all recovered after treatment. The diagnosis of primary pyogenic abscess requires a high index of suspicion and the best treatment is early operative drainage and administration of systemic antibiotics. PMID:9549580

    From 1993 to 1998, 29 pyogenic psoas abscesses occurring in 27 patients were seen in Taichung Veterans General Hospital. Their age range was 25 to 85 years. Diabetes mellitus was the leading underlying disease. Fever and pain in the flank area, back and hip were the usual manifestations. The duration of symptoms prior to the diagnosis ranged from 3 days to 6 months. Most abscesses were diagnosed by computed tomography (CT) images and proven by abscess cultures, which were divided into primary and secondary types. Eighteen of 29 abscesses were regarded as primary. Staphylococcus aureus was the most common pathogen in the primary abscesses, followed by Streptococcus agalactiae, Escherichia coli, viridans streptococci, S. epidermidis, and Salmonella spp.. In the secondary abscess category, E. coli was the leading organism in this series, followed by S. aureus, Klebsiella pneumoniae, viridans streptococci and Candida albicans. The associated conditions included epidural abscess, osteomyelitis, septic arthritis, perirenal abscess, pulmonary tuberculosis, empyema, hydronephrosis and trauma history. The initial empiric therapy comprised mostly of cefazolin or oxacillin with or without an aminoglycoside. Thirteen patients underwent percutaneous drainage, while six received surgical debridement, including two with a recurrent abscess. One patient had both drainage and debridement. Others received medical treatment only. Two of the patients with primary abscess died in spite of percutaneous drainage. Therefore, open drainage, besides appropriate antibiotic treatment, is still required to control complex abscesses with sepsis. PMID:10650491

    Summary Background Liver abscess (LA) is an uncommon but potentially life-threatening disease with significant morbidity and mortality. Methods This review comprehensively describes epidemiology, pathogenesis, diagnosis, and treatment of LA, with a strong focus on antimicrobial treatment choices and the impact of multidrug-resistant pathogens. Results In industrialized areas, pyogenic liver abscess (PLA) accounts for over 80% of the cases, whereas Entamoeba histolyticais responsible for up to 10% of the cases, with a higher incidence in tropical areas. Highly virulent strains of Klebsiella pneumoniaehave emerged as a predominant cause of PLA in Asian countries and tend to spread to the USA, Australia, and European countries, therefore requiring special alertness. Most common symptoms of LA are fever, chills, and right upper quadrant abdominal pain, although a broad spectrum of non-specific symptoms may also occur. Conclusion Imaging studies (ultrasound, computed tomography scan) and microbiological findings play a crucial role in the diagnosis of LA. The treatment of choice for PLA is a multimodal approach combining broad-spectrum antibiotics and aspiration or drainage of larger abscess cavities. Amebic LA can be cured by metronidazole therapy without drainage. PMID:26287275

    Primary pyogenic psoas abscess, although quite a common condition, particularly in the tropics, is often overlooked as a clinical entity, probably because a psoas abscess has been traditionally associated with tuberculous spondylitis. The abscess is easily diagnosed by ultrasonography (US). Treatment by open drainage and antibiotics effective against Staphylococcus aureus results in complete reversal of symptoms and signs. In our series of 55 cases in the pediatric age group (0-12 years), pain and flexion at the hip were the most frequent clinical features at presentation. US was diagnostic in all cases in which it was performed. All except 1 patient showed complete resolution with extraperitoneal drainage, antibiotics, and skin traction. Although 4% of the cases were associated with suppurative external-iliac lymphadenitis, the remaining ones arose de novo in the psoas sheath, suggesting a primary pyomyositis of the psoas muscle.

    Fusobacterium is well characterized as an oropharyngeal pathogen that may induce a septic thrombophlebitis by direct extension of abscess into an adjacent neck vessel (Lemierre's syndrome); its potential for visceral abscess formation, however, remains under-recognized. A 65-year-old man with a recent history of multiple rim-enhancing liver lesions presented to the emergency room with fever and abdominal pain. Based on interval increase in the size of the lesions, abscess was suspected. A liver biopsy was performed, and although no organism could be identified on routine microscopy, Warthin-Starry stain revealed Gram-negative bacilli consistent with an anaerobic Fusobacterium species as the underlying etiology of liver abscess formation. Subsequent anaerobic culture results confirmed the diagnosis. This case highlights the importance of consideration for Fusobacterium infection in the setting of liver abscess if anaerobic organisms have not yet been excluded on initial culture evaluation.

    Objectives To identify the variables that predict the failure to treat amoebic liver abscesses. Methods We prospectively carried out a case–control study on a cohort of patients who had been diagnosed with amoebic liver abscesses using clinical, ultrasonic, and serologic methods. Patients with pyogenic abscesses, negative ELISA tests for amoebiasis, immunosuppression status, or previous abdominal surgery were excluded. All patients received metronidazole, and those who demonstrated 4 days of unfavorable clinical responses received percutaneous or surgical draining of the abscess. Demographic, laboratory, and ultrasonographic characteristics were assessed as prognostic indications of failure. Results Of 40 patients with amoebic liver abscess, 24 (mean age: 36.7±11.2 years) responded to medical treatment and 16 (41.8±11.6 years) required drainage, including 14 patients who underwent percutaneous drainage and two patients who required surgery. The albumin level, abscess volume, abscess diameter, and alkaline phosphatase level were all statistically significant (P<0.05) on the bivariate analysis. The highest (>99%) sensitivity and negative predictive value were observed for an abscess volume >500 ml and diameter >10 cm, while the best specificity and positive predictive value were achieved with the combination of low serum albumin level, high alkaline phosphatase level, and large abscess volume or diameter. Conclusions The prognostic indications of the failure to treat amoebic liver abscesses include low albumin, high alkaline phosphatase, and large abscess volume or diameter. The combination of these variables is a useful and easy tool for determining appropriate therapy. PMID:23265424

During follow-up, he presented with recurrent pyogenic meningitis with persistence of the lesion, therefore a diagnosis of pituitary abscess was considered. He underwent trans-sphenoidal surgery (TSS) with evacuation of pus and received antibiotic treatment for the same. After this he remarkably improved and had no recurrence of symptoms. He is on levothyroxine, glucocorticoids and testosterone replacement therapy for his respective hormone deficits. PMID:22767626

    2013-01-01

    Liver abscesses are infectious, space occupying lesions in the liver, the two most common abscesses being pyogenic and amoebic. A pyogenic liver abscess (PLA) is a rare condition with a reported incidence of 20 per 100 000 hospital admissions in the western population. The right lobe of the liver is the most common site in both types of liver abscess. Clinical presentation is elusive with complaints of fever, right upper quadrant pain in the abdomen and hepatomegaly with or without jaundice. The aetiology of PLA has changed in the past few decades and may be of biliary, portal, arterial or traumatic origin, but many cases are still cryptogenic. The most common organisms causing PLA are Gram-negative aerobes, especially Escherichia coli and Klebsiella pneumoniae. Studies have shown a high degree of antimicrobial susceptibility of isolated organism resulting in an overall lower mortality in PLA. Here, we present a case of PLA caused by multidrug-resistant Citrobacter freundii, which is an unusual organism to be isolated. PMID:23608848

    Bacterial flora of liver abscesses from cattle fed tylosin or no tylosin and susceptibilities of the predominant bacterial isolates to tylosin and other antimicrobial compounds were determined. Abscessed livers were collected at slaughter from cattle originating from feedlots that had fed tylosin (n = 36) or no tylosin (n = 41) for at least 2 yr, and segments of livers with one or two intact abscesses were transported to the laboratory. Abscesses were cultured for anaerobic and facultative bacteria. Fusobacterium necrophorum, either as single culture or mixed with other bacteria, was isolated from all abscesses. The incidence of subsp. necrophorum, as part of the mixed infection, was lower (P < .05) in the tylosin group than in the no-tylosin group (33 vs 61%). However, the incidence of Actinomyces pyogenes was higher (P < .01) in the tylosin group than in the no-tylosin group (53 vs 10%). Totals of 119 F. necrophorum and 21 A. pyogenes isolates were used for determinations of susceptibilities to bacitracin, oxytetracycline, chlortetracycline, lasalocid, monensin, tylosin, tilmicosin, and virginiamycin. The minimum inhibitory concentrations (MIC) of antibiotics were determined with a broth microdilution method. The mean MIC of tylosin for F. necrophorum and A. pyogenes were not different between isolates from tylosin and no-tylosin groups. We concluded that continuous feeding of tylosin did not induce resistance in F. necrophorum or A. pyogenes. Also, the higher incidence of mixed infection of F. necrophorum and A. pyogenes in liver abscesses of tylosin-fed cattle suggests a potential synergistic interaction between the two organisms in causing liver abscesses.

The lack of history of ingestion of foreign bodies, variable clinical presentation of the conditions and radiolucent natures of the foreign bodies all play a role in impeding the diagnosis preoperatively. This report emphasizes the role of ultrasound and computed tomographic scan in evaluating similar cases. Any patient with known risk factors for ingestion of foreign body should arouse suspicion and be investigated further. PMID:9286481

    For reasons which are not quite clear amoebic liver abscesses in the left lobe are relatively uncommon. On account of the lesser bulk of the left lobe, and the potentially greater space under the left hemidiaphragm, expansive lesions within it remain less obtrusive than corresponding lesions in the right. Sixteen such cases are analysed and five distinct modes of clinical presentation have been found. Eight of the patients presented late with perforation into either the peritoneal or pleural cavities. In seven of eight remaining cases, an abdominal mass suggestive of a left lobe lesion was present. Anaemia, leucocytosis and a raised erythrocyte sedimentation rate were usually present, and in the five cases seen in the last year a positive reaction was obtained to the indirect fluorescent antibody test. Confirmatory radiological features were present only in advanced cases. ImagesFig. 2Fig. 3Fig. 4Fig. 5 PMID:959101

    Abstract To investigate the clinical features, risk factors, and bacterial spectrum of liver abscess following transarterial chemoembolization (TACE) and evaluate the therapeutic effect of percutaneous catheter drainage (PCD) on the abscesses. A retrospective review of patient charts was performed in 3613 patients who suffered from liver malignancies (2832 patients with hepatocellular carcinoma and 781 with metastatic hepatic tumor) and had undergone 11,054 TACE procedures from January 2005 to October 2013. Liver abscesses were found in 21 patients. PCD was performed in all abscess patients. The clinical features, risk factors, and bacterial spectrum of liver abscess following TACE were investigated and the therapeutic effect of PCD was evaluated. The incidence of liver abscess was 0.58% per patient and 0.19% per procedure. Approximately 57.1% of the patients had a medical history of bilioenteric anastomosis or biliary stent implantation. On computed tomography scans, the abscesses appeared as low-attenuation lesions and high-density iodinate oil scattered in the abscesses. The ultrasound showed the well defined, heterogeneously hypoechoic lesions. Positive microbiological isolates were obtained in all pus cultures and in 47.6% of blood cultures. The most common bacterium was Escherichia coli (52.4%). Twenty patients (95.2%) were cured from abscesses by using PCD, and 1 died of sepsis. Patients with predisposing factors are prone to an increased risk of liver abscess following TACE. Bacterial culture and antibiotic sensitivity tests on pus and blood help on the antibiotics selection. PCD combined with aggressive antibiotics can be recommended as the first-line therapeutic regimen. PMID:27124055

    Introduction. Klebsiella pneumoniae is a well-known cause of liver abscess. Higher rates of liver abscess associated with Klebsiella pneumoniae are seen in Taiwan. Metastatic endophthalmitis is a common complication associated with a poor prognosis despite aggressive therapy. Case Report. We report a case of a 67-year-old Korean female with Klebsiella pneumoniae liver abscess. The patient developed metastatic endophthalmitis and ultimately succumbed to her disease despite aggressive medical and surgical treatment. Conclusion. Dissemination of Klebsiella pneumoniae is associated with significant morbidity and mortality. Liver abscesses preferably should be treated with percutaneous drainage, but surgical treatment is needed in some cases. Metastatic spread to the eye is a common complication that must be treated aggressively with intravenous antibiotics and surgical intervention if necessary. PMID:26788530

    Streptococcus intermedius is a member of the Streptococcus anginosus group of bacteria. This group is part of the normal flora of the oropharynx, genitourinary, and gastrointestinal tracts; however, they have been known to cause a variety of purulent infections including meningitis, endocarditis, and abscesses, even in immunocompetent hosts. In particular, S. intermedius has been associated with the development of liver and brain abscesses. There have been several case reports of S. intermedius liver abscesses with active periodontal infection. To our knowledge, however, there has not been a case following a routine dental procedure. In fact, the development of liver abscesses secondary to dental procedures is very rare in general, and there are only a few case reports in the literature describing this in relation to any pathogen. We present a rare case of S. intermedius bacteremia and liver abscess following a dental cleaning. This case serves to further emphasize that even routine dental procedures can place a patient at risk of the development of bacteremia and liver abscesses. For this reason, the clinician must be sure to perform a detailed history and careful examination. Timely diagnosis of pyogenic liver abscesses is vital, as they are typically fatal if left untreated. PMID:25197585

    Brain abscesses develop in response to a parenchymal infection with pyogenic bacteria, beginning as a localized area of cerebritis and evolving into a suppurative lesion surrounded by a well-vascularized fibrotic capsule. The leading etiologic agents of brain abscess are the streptococcal strains and S. aureus. Abscesses may also be secondary to fungal or parasitic organisms. Brain abscess represents a significant medical problem, accounting for one in every 10,000 hospital admissions in the United States, and remains a serious situation despite recent advances made in detection and therapy. These lesions often produce complex clinical and radiologic findings and require prompt recognition and treatment to avoid a fatal neurologic outcome. Subdural empyema represents an important type of intracranial suppurative infectious-inflammatory disorder. Clinically, these patients initially have signs and symptoms of meningitis, but this course might be complicated later by the development of seizures and focal neurologic signs. PMID:24029180

    The incidence of spinal infections has increased in the past two decades, owing to the increasing number of elderly patients, immunocompromised conditions, spinal surgery and instrumentation, vascular access and intravenous drug use. Conventional MRI is the gold standard for diagnostic imaging; however, there are still a significant number of misdiagnosed cases. Diffusion-weighted imaging (DWI) with a b-value of 1000 and apparent diffusion coefficient (ADC) maps provide early and accurate detection of abscess and pus collection. Pyogenic infections are classified into four types of extension based on MRI and DWI findings: (1) epidural/paraspinal abscess with spondylodiscitis, (2) epidural/paraspinal abscess with facet joint infection, (3) epidural/paraspinal abscess without concomitant spondylodiscitis or facet joint infection and (4) intradural abscess (subdural abscess, purulent meningitis and spinal cord abscess). DWI easily detects abscesses and demonstrates the extension, multiplicity and remote disseminated infection. DWI is often a key image in the differential diagnosis. Important differential diagnoses include epidural, subdural or subarachnoid haemorrhage, cerebrospinal fluid leak, disc herniation, synovial cyst, granulation tissue, intra- or extradural tumour and post-surgical fluid collections. DWI and the ADC values are affected by susceptibility artefacts, incomplete fat suppression and volume-averaging artefacts. Recognition of artefacts is essential when interpreting DWI of spinal and paraspinal infections. DWI is not only useful for the diagnosis but also for the treatment planning of pyogenic and non-pyogenic spinal infections. PMID:24999081

    The incidence of spinal infections has increased in the past two decades, owing to the increasing number of elderly patients, immunocompromised conditions, spinal surgery and instrumentation, vascular access and intravenous drug use. Conventional MRI is the gold standard for diagnostic imaging; however, there are still a significant number of misdiagnosed cases. Diffusion-weighted imaging (DWI) with a b-value of 1000 and apparent diffusion coefficient (ADC) maps provide early and accurate detection of abscess and pus collection. Pyogenic infections are classified into four types of extension based on MRI and DWI findings: (1) epidural/paraspinal abscess with spondylodiscitis, (2) epidural/paraspinal abscess with facet joint infection, (3) epidural/paraspinal abscess without concomitant spondylodiscitis or facet joint infection and (4) intradural abscess (subdural abscess, purulent meningitis and spinal cord abscess). DWI easily detects abscesses and demonstrates the extension, multiplicity and remote disseminated infection. DWI is often a key image in the differential diagnosis. Important differential diagnoses include epidural, subdural or subarachnoid haemorrhage, cerebrospinal fluid leak, disc herniation, synovial cyst, granulation tissue, intra- or extradural tumour and post-surgical fluid collections. DWI and the ADC values are affected by susceptibility artefacts, incomplete fat suppression and volume-averaging artefacts. Recognition of artefacts is essential when interpreting DWI of spinal and paraspinal infections. DWI is not only useful for the diagnosis but also for the treatment planning of pyogenic and non-pyogenic spinal infections. PMID:24999081

    We describe four cases of multiple, cryptogenic, and streptococcal liver abscesses which were cured with antibiotic therapy. Two of the patients were referred for medical management as a last resort after open surgical drainage failed to eradicate the suppurative process. The other two patients were treated from the time of diagnosis with antimicrobial agents alone. Blood cultures or needle aspirates of the abscesses yielded a pure growth of streptococci in all instances. All isolates were susceptible to penicillin G. Cryptogenic streptococcal abscesses may represent a subset of multiple hepatic abscesses particularly amenable to successful medical therapy consisting of a minimum of 6 weeks parenteral antibiotic therapy followed by a period of oral antibiotics until clinical, biochemical, and radiological resolution of the abscesses has occurred.

    Study Design A retrospective study. Purpose The purpose of this study was to evaluate outcomes in patients with pyogenic spondylitis accompanied by iliopsoas abscess who were treated by percutaneous drainage combined with hyperbaric oxygen (HBO) therapy. Overview of Literature To the best of our knowledge, there have been no previous reports of the use of percutaneous drainage combined with HBO therapy for the treatment of this condition. Methods Twenty-three patients (13 men, 10 women; mean age, 69.0 years; range, 45-85 years) were treated with percutaneous drainage combined with HBO therapy in addition to commonly used conservative therapy. Mean follow-up duration was 27.7 months (range, 12-48 months). Clinical outcomes and imaging examinations were retrospectively investigated. Results Symptoms such as low back pain, radicular pain, and hip pain resolved in all patients immediately after treatment. Mean time from the start of treatment to the return of C-reactive protein levels to normal or baseline values recorded before the onset of spondylitis was 28.3 days (range, 8-56 days). In the final set of follow-up radiographic studies, all patients were free from progressive destructive changes. Follow-up magnetic resonance images or computed tomography with contrast enhancement confirmed the disappearance or near-total resolution of the iliopsoas abscess cavity with healing of the pyogenic spondylitis in all 23 patients. No recurrences were observed during follow-up. Conclusions The present study suggests that patients with pyogenic spondylitis accompanied by iliopsoas abscess can be cured without a prolonged period of therapy or recurrence using this treatment.

    Nursery-age pigs (n=198) were used to evaluate the difference in abscess formation at needle-free jet and conventional needle-and-syringe injection sites. Needle-free jet injection was used to administer injections in the neck and ham on one side of the animal whereas needle-and-syringe was used for neck and ham injections on the opposite side. Immediately prior to injection, the injection site surfaces were contaminated with an inoculum of Arcanobacterium pyogenes. Each pig was humanely euthanized 27 or 28 days after injections. Histopathological results showed that needle-free jet injection was associated with more abscesses than needle-and-syringe injection at both neck (P=0.0625) and ham (P=0.0313) injection sites. Out of 792 injection sites, only 13 abscesses were observed, with 12 of those present at needle-free jet injection sites. Needle-free jet injection may increase the occurrence of injection site abscesses that necessitate carcass trimming at pork processing plants. PMID:22854129

    Case Presentation. This is a case of a 44-year-old male, farmer, known to be diabetic, presenting with two-week history of vague abdominal pain associated with high grade fever. Abdominal CT scan showed localized liver abscess at segment 8 measuring 7.5 × 6.8 × 6.1 cm. Patient subsequently underwent laparoscopic ultrasound guided pigtail insertion for drainage of abscess. Culture studies showed moderate growth of Burkholderia pseudomallei in which the patient completed seven days of IV Meropenem. On follow-up after 12 weeks of oral Sulfamethoxazole/Trimethoprim, taken twice a day, the patient remained asymptomatic with no residual findings based on the abdominal ultrasound. Discussion. Diagnosis of melioidosis, a known "great masquerader," relies heavily on culture studies. Consensus with regard to the management of liver abscess caused by Burkholderia pseudomallei has not yet been established due to the rarity of cases. Surgical intervention through either a percutaneous or open drainage has shown good outcomes compared to IV antibiotics alone. In Philippines, the possibility of underreporting is highly plausible. This write-up serves not only to report a rare presentation of melioidosis but also to add to the number of cases reported in the country, possibly indicative of disease emergence. PMID:27529039

    Invasive infections caused by Brevundimonas vesicularis are very rare in humans. We experienced an unusual case of liver abscess due to B. vesicularis in an immunocompetent young male. The patient was successfully treated by liver abscess drainage and with antimicrobial therapy of ceftriaxone followed by ampicillin/sulbactam. The organism found in the aspiration culture of the abscess material was initially reported, by using a VITEK 2 system, as Sphingomonas paucimobilis. However, later, B. vesicularis was confirmed as the true pathogen through 16S rRNA gene sequencing. To our knowledge, this is the first case of liver abscess caused by B. vesicularis. PMID:22767540

    A diverse group of the pathologic process can produce the enlargement of soft tissues in the oral cavity and often present a diagnostic challenge. This soft tissue enlargement may represent a variation of the normal anatomic structure, inflammatory reaction, cyst, neoplasm, and developmental anomalies. A group of reactive hyperplasias, which develop in response to chronic recurring tissue injury that stimulates an excessive tissue repair response. The pyogenic granuloma (PG) is a reactive enlargement that is an inflammatory response to local irritation such as calculus, a fractured tooth, rough dental restoration, and foreign materials or hormonal (pregnancy tumor) and rarely associated with bone loss. This paper presents a rare case of PG associated with periodontal abscess and bone loss in a 30-year-old male. PMID:22090773

    Background. Tuberculosis of the liver without active pulmonary or miliary tuberculosis is considered as an uncommon diagnosis. The aim of the present study was to determine the etiological role of tuberculosis in adult patients presenting with features of liver abscess. Methods. A total of 40 patients with liver abscess were included in the study. The liver abscess aspirate was subjected to microscopy, culture, and polymerase chain reaction to determine the role of tuberculosis as an etiological factor in liver abscess. Results. Of the 40 patients enrolled, 25% (10/40) were diagnosed with having tubercular liver abscess. In a total of 40 specimens, 2.5% (1/40) were positive for acid fast bacilli by Ziehl-Neelsen method, while 10% (4/40) were positive for M. tuberculosis by culture using BACTEC 460 and the yield increased to 25% (10/40) by polymerase chain reaction for M. tuberculosis. Conclusion. 25% of the patients presenting with liver abscess had tubercular etiology without features of active pulmonary or miliary tuberculosis. Liver can act as the primary site of involvement in the absence of activity elsewhere in the body. Tuberculosis should be considered as an important differential diagnosis of liver abscess irrespective of evidence of active tuberculosis elsewhere in the body. PMID:27595021

    Of 210 patients with hepatocellular carcinoma (n = 135), metastatic liver cancer (n = 71) and cholangiocarcinoma (n = 4) who underwent intra-arterial infusion of adriamycin and/or mitomycin C oil suspension (ADMOS) and cisplatin, and both regimens, pyogenic liver abscess occurred in seven (3.3%). The percentages of abscess formation in the respective types of liver cancer were 0.8, 7.0 and 25%. These differences among the three types of liver cancer were attributed to the volume of the tumor vascular beds to be embolized, which might determine the relative amount or regional Lipiodol retention in the tumor and normal liver tissue. Four of seven patients with hepatic abscess had received the intra-arterial infusion of ADMOS, and their angiographic findings showed sequential decreases in the vascular beds of the tumor in comparison with those of previous infusion procedures; all had hypovascular liver tumors angiographically. We have never experienced this complication in other treatments such as embolization of the hepatic arteries and intra-arterial infusion of water-soluble anticancer drugs alone. These results suggest that the most important factor leading to abscess formation is the ischemic destruction of the intrahepatic ducts secondary to occlusion of the peribiliary arterial plexus by Lipiodol and/or the direct effects of anticancer drugs on these vessels. To avoid this complication, the volume of Lipiodol used for intraarterial infusion therapy should be carefully determined, especially when the patient has hypovascular tumors of the liver and a history of multiple previous intraarterial infusion procedures of anticancer drug. The use of ADMOS should be avoided in patients with hypovascular tumors of the liver such as secondary deposits and cholangiocarcinoma. PMID:1313961

    Entamoeba histolytica is a causative agent of amoebic liver abscess (ALA) and is endemic in many underdeveloped countries. We investigated antigenic E. histolytica proteins in liver abscess aspirates using proteomics approach. Pus samples were first tested by real-time PCR to confirm the presence of E. histolytica DNA and the corresponding serum samples tested for E. histolytica-specific IgG by a commercial ELISA. Proteins were extracted from three and one pool(s) of pus samples from ALA and PLA (pyogenic liver abscess) patients respectively, followed by analysis using isoelectric focussing, SDS-PAGE and Western blot. Unpurified pooled serum samples from infected hamsters and pooled human amoebic-specific IgG were used as primary antibodies. The antigenic protein band was excised from the gel, digested and analysed by MALDI-TOF/TOF and LC-MS/MS. The results using both primary antibodies showed an antigenic protein band of ∼14kDa. Based on the mass spectrum analysis, putative tyrosine kinase is the most probable identification of the antigenic band. PMID:23680184

    Pyogenic sacroiliitis is a rare entity in children. Diagnosis is often delayed because of its variable clinical presentation, low suspicion by the examining physician, and rare findings on radiographs. Delayed diagnosis, however, results in complications such as iliopsoas abscess. We report the case of a 12-year-old girl hospitalized with a 21-day history of fever, pain in the left iliac fossa, and flexion contracture of the hip. On examination, she had fever (38.9 degrees C), psoitis, localized tenderness at the left sacroiliac joint, and pain elicited by lateral compression of the pelvis. The abdominal examination was normal. The erythrocyte sedimentation rate was 130 mm in the first hour, C-reactive protein was 186 mg/l, and the white blood cell count was 18,400/mm(3), with 79% neutrophils. Urinalysis was normal. Blood cultures were negative. Radiographs of the pelvis showed irregular left sacroiliac borders. The CT scan provided the diagnosis of sacroiliitis complicated by an ilioapsoas abcsess. Treatment was based on antibiotic therapy associated with surgical drainage. Bacteriologic investigation revealed Staphylococcus aureus. The patient's temperature returned to normal on the second day. Antibiotics were continued for 3 months, leading to full recovery. PMID:19962864

    Introduction: Brodie’s abscess of cuboid bone is one of the rarest diagnosis in children which most often is hematogenous in origin. Although Streptococcus pyogenes has been uncommonly implicated as causative organism in other bones, it is not yet reported in the cuboid. Case Report: We report the case of 14-year-old boy who presented with a lytic lesion in the cuboid bone. It was preceded by a penetrating injury with a small iron nail. He was treated with simple curettage without the addition of bone graft. Frank pus present in the cavity in the cuboid bone grew S. pyogenes on bacterial culture. Symptoms resolved after 6 weeks of antibiotics, however, complete radiological healing was obtained after 9 months. Conclusion: Although very rare, S. pyogenes associated Brodie’s abscess should strongly be suspected in a posttraumatic lytic lesion in the cuboid bone and bone grafting is not always required for bone healing even in presence of large pus-filled cavity.

    Protozoal infections are common in the tropics. Amoebic colitis is the commonest of these infections and can lead to liver abscess as a complication. Balantidium coli is a rare free moving protozoal parasite which is known to infest human large intestine causing a type of colitis very similar to that caused by Entamoeba histolytica. However this pathogen is not known to cause liver invasion in humans. We report here a case of liver abscess caused by B. coli, which is probably the first such case reported in Indian literature.

    Two rare cases of amebic pericardial effusion as a complication of amoebic liver abscess in the left lobe are described. The pericardial amebiasis should be suspected in a patient presenting with signs and symptoms of pericardial effusion with an evidence of hepatic abscess (in the left lobe) or in a patient with pericardial effusion of uncertain etiology. Aspiration of "anchovy sauce" pus from both the pericardial cavity and the liver should be regarded as confirming the diagnosis of amebic pericarditis secondary to amebic liver abcess because demonstration of Entamoeba hystolytica is seldom possible. Removal of pericardial pus and metronidazole intake were markedly effective in treating our patients. PMID:123716

    AIM: To evaluate the clinical characteristics and progression of liver abscess caused by toxocara. METHODS: We retrospectively reviewed the medical records of patients with serum IgG antibody to Toxocara canis and liver abscess diagnosed using abdominal computed tomography between February 2010 and February 2015. Among 84 patients exhibiting serum IgG antibody to Toxocara canis, 34 patients were diagnosed with liver asbscess and treated with albendazole. A follow-up period of 1 year was conducted. RESULTS: Mean patient age was 53 (34-79) years, with 26 (76.5%) patients being male. Twenty-one (61.7%) patients were moderate or heavy drinkers, 23 (67.6%) patients had a history of eating raw meat or liver and 6 (17.6%) patients owned pet dogs or cats. Main patient symptoms consisted of right upper quadrant pain, fever, and fatigue; 18 (52.9%) patients, however, presented with no symptoms. Lung involvement was detected in 444 (11.7%) patients. The eosinophil count increased in 29 (85.3%) patients at initial diagnosis, and decreased in most patients after albendazole treatment. The initial serum IgE level increased in 25 (73.5%) patients, but exhibited various response levels after albendazole treatment. Liver abscess formation improved in all patients. CONCLUSION: The liver abscess was improved with albendazole treatment. PMID:27366302

    Hypervirulent Klebsiella pneumoniae is an emerging cause of community-acquired pyogenic liver abscess. First described in Asia, it is now increasingly recognized in Western countries, commonly afflicting those with Asian descent. This raises the question of genetic predisposition versus geospecific strain acquisition. We leveraged on the Antibiotics for Klebsiella Liver Abscess Syndrome Study (A-KLASS) clinical trial ongoing in ethnically diverse Singapore, to prospectively examine the profiles of 70 patients together with their isolates’ genotypic and phenotypic characteristics. The majority of isolates belonged to capsule type K1, a genetically homogenous group corresponding to sequence-type 23. The remaining K2, K5, K16, K28, K57 and K63 isolates as well as two novel cps isolates were genetically heterogeneous. K1 isolates carried higher frequencies of virulence-associated genes including rmpA (regulator of mucoid phenotype A), kfu (Klebsiella ferric uptake transporter), iuc (aerobactin), iro (salmochelin) and irp (yersiniabactin) than non-K1 isolates. The Chinese in our patient cohort, mostly non-diabetic, had higher prevalence of K1 infection than the predominantly diabetic non-Chinese (Malays, Indian and Caucasian). This differential susceptibility to different capsule types among the various ethnic groups suggests patterns of transmission (e.g. environmental source, familial transmission) and/or genetic predisposition unique to each race despite being in the same geographical location.

    Patient: Male, 47 Final Diagnosis: Bilateral psoas abscess • acute lower extremity deep vein thrombosis • bilateral pulmonary embolism Symptoms: Progressive left leg swelling • productive cough with whitish sputum • right flank pain Medication: Antibiotics and anticoagulation Clinical Procedure: CT-guided percutaneous drain placement Specialty: Internal Medicine/Critical Care Objective: Unusual presentation Background: Psoas abscesses are a known cause of back pain, but they have not been reported as a cause of acute lower extremity thromboses and bilateral pulmonary emboli. We report a patient with bilateral psoas abscesses causing extensive pulmonary emboli through compression of the iliac vein. Case Report: A 47-year-old man presented with bilateral leg swelling over 4 weeks. Physical examination revealed a thin male with bilateral leg swelling, extending to the thigh on his left side. He had hemoglobin of 10.5 g/dl, leukocytosis of 16 000/ml, and an elevated D-dimer. A computed tomography (CT) angiogram of his chest showed extensive bilateral pulmonary emboli and infarcts. He remained febrile with vague flank pain, prompting a CT of his abdomen and pelvis that showed large, multiloculated, septated, bilateral psoas abscesses with compression of the left femoral vein by the left psoas abscess and a thrombus distal to the occlusion. Two liters of pus was drained from the left psoas abscess by CT-guidance, and although the Gram staining showed Gram-positive cocci in clusters, cultures from the abscess and blood were negative. A repeat CT showed resolution of the abscesses, and the drain was removed. He was discharged to a nursing home to complete a course of intravenous antibiotics and anticoagulation. Conclusions: Although the infectious complications of psoas abscesses have been described in the literature, the mechanical complications of bilateral psoas abscesses are lacking. It is important to assess for complete resolution of psoas abscesses through

    Background Abscesses involving the inguinal region as manifestations of complex soft-tissue infections are rare, and the infectious route is usually unclear. The purpose of this study was to ascertain the importance of imaging study and whether the clinical presentations differ between the extrapelvic and intrapelvic origin. Methods Patients who presented with inguinal abscess between January 2003 and December 2010 were evaluated retrospectively. All patients received broad-spectrum antibiotic therapy and debridement. Imaging studies, including computed tomography or magnetic resonance imaging, were performed in all patients to elucidate the origin and extent of infectious disease, and the results were reviewed. Clinical data, laboratory examination findings, and culture results were analyzed. Results Twenty-eight patients were enrolled in the study: 13 patients whose infections were of extrapelvic origin (Group 1) and 15 patients of intrapelvic origin (Group 2). Imaging studies yielded information that helped guiding the treatment. Gram-positive coccus infection was more frequent in Group 1 (p < 0.001), while mixed pathogen and anaerobic bacterial infection were more frequent in Group 2 (p = 0.002 and p = 0.006, respectively). Group 2 had a higher incidence of history of malignancy and chronic renal failure (p = 0.044 and p = 0.038, respectively). Conclusions Computed tomography and magnetic resonance imaging are helpful in diagnosing cases of inguinal abscess and determining the extent of infection. In patients presenting with acute pyogenic inguinal abscess, a higher prevalence of chronic renal failure and history of malignancy were found in those with an intrapelvic, as compared with an extrapelvic, origin of infection.

    Background Amoebic liver abscess (ALA) and pyogenic liver abscesses (PLA) appear identical by ultrasound and other imaging techniques. Collection of blood or liver abscess pus for diagnosis of liver abscesses is an invasive procedure, and the procedure requires technical expertise and disposable syringes. Collection of urine is a noninvasive procedure. Therefore, there has been much interest shown towards the use of urine as an alternative clinical specimen for the diagnosis of some parasitic infections. Here, we report for the first time the detection of E. histolytica DNA excreted in the urine for diagnosis of the cases of ALA. Results E. histolytica DNA was detected in liver abscess pus specimen of 80.4% of ALA patients by a nested multiplex polymerase chain reaction (PCR) targeting 16S-like r RNA gene. The nested PCR detected E. histolytica DNA in all 37 (100%) liver abscess pus specimens collected prior to metronidazole treatment, but were detected in only 53 of 75 (70.6%) pus specimens collected after therapy with metronidazole. Similarly, the PCR detected E. histolytica DNA in 21 of 53 (39.6%) urine specimens of ALA patients. The test detected E. histolytica DNA in only 4 of 23 (17.4%) urine specimens collected prior to metronidazole treatment, but were detected in 17 of 30 (56.7%) urine specimens collected after treatment with metronidazole. The enzyme-linked immunosorbent assay (ELISA) for the detection of lectin E. histolytica antigen in the liver abscess pus showed a sensitivity of 50% and the indirect haemagglutination (IHA) test for detection of amoebic antibodies in the serum showed a sensitivity of 76.8% for the diagnosis of the ALA. Conclusion The present study for the first time shows that the kidney barrier in ALA patients is permeable to E. histolytica DNA molecule resulting in excretion of E. histolytica DNA in urine which can be detected by PCR. The study also shows that the PCR for detection of E. histolytica DNA in urine of patients with ALA

    We describe the case of a patient with sigmoid colon cancer liver metastasis accompanied by multiple liver abscesses. The 59-year-old female patient presented with a fever at a body temperature of 39.0°C. On abdominal computed tomography (CT), multiple liver abscesses were detected, and percutaneous transhepatic abscess drainage (PTAD) was performed. The day after the PTAD, the patient's fever subsided and her inflammatory response abated. A lower gastrointestinal examination, performed to identify the origin of her symptoms, revealed a type 1 tumor in the sigmoid colon. A biopsy indicated a moderately differentiated adenocarcinoma. Prior to surgery, a second abdominal CT scan was performed, and a single liver metastasis was detected. Laparoscopic sigmoidectomy and partial liver resection were simultaneously performed. The histopathological diagnosis of the colon cancer was tub2, pN1, pH1, P0, ly1, v1, stage IV. To date, the patient remains free from hepatic abscess and colon cancer recurrence. Gastrointestinal examinations should be performed as early as possible to identify the cause of hepatic abscesses. Moreover, therapeutic decisions should only be made after imaging and examinations have been performed, which will be sufficient to identify the presence of liver metastases. PMID:25731285

    The complete sequence of morphologic events during amebic liver abscess formation in the hamster has been studied, from the lodgement of amebas in the hepatic sinusoids to the development of extensive liver necrosis. Following intraportal inoculation of live amebas, the early stages of the lesion (from 1 to 12 hours) were characterized by acute cellular infiltration composed of an increasingly large number of polymorphonuclear leukocytes, which surrounded centrally located trophozoites. Histiocytes and lysed leukocytes were situated on the periphery of the lesions. Hepatocytes close to the early lesions showed degenerative changes which led to necrosis; however, direct contact of liver cells with amebas was very rarely observed. At later stages, the extent of necrosis increased, macrophages and epithelioid cells replaced most leukocytes, and well-organized granulomas developed. Extensive necrosis associated with fused granulomas was present by Day 7. The results suggest that Entamoeba histolytica trophozoites do not produce amebic liver abscesses in hamsters through direct lysis of hepatocytes. Rather, tissue destruction is the result of the accumulation and subsequent lysis of leukocytes and macrophages surrounding the amebas.

    Solitary small (<5 cm) amoebic liver abscesses in the right lobe are generally treated using medication alone, while large abscesses are typically treated via a combination of medication and drainage. However, the therapeutic indications for multiple medium (5-10 cm) amoebic liver abscesses remain unclear. We herein report the findings of a 53-year-old woman who was receiving lenalidomide for multiple myeloma and subsequently developed multiple amoebic abscesses. Metronidazole alone was unsuccessful, although metronidazole and repeated percutaneous catheter drainage of the right lobe, left lobe, and thorax proved to ultimately be successful. Therefore, the successful use of medication alone may be associated with the total combined abscess volume. PMID:27523014

    Streptococcus salivarius is an oral commensal bacterium that rarely causes disease in humans. Here, we report a case of liver abscess associated with S. salivarius in a 41-year-old woman who presented with continuous abdominal discomfort, fatigue, and fever. She was diagnosed with multiple liver abscesses; she underwent percutaneous transhepatic abscess drainage. Thereafter, S. salivarius was isolated in all bacterial cultures of the drained abscesses, and it was sensitive to penicillins. She made a good recovery after treatment. In the absence of an infective source other than chronic periodontitis, the cause of liver abscesses was attributed to oral S. salivarius. S. salivarius is a normal oral commensal, and oral commensals must be considered if the infective origin of liver abscess cannot be determined. PMID:25100350

    Desulfovibrio spp. are gram-negative, sulfate-reducing, and anaerobic bacteria found in the digestive tract of humans. Because Desulfovibrio spp. are infrequent causative agents of infectious diseases and are difficult to isolate and to identify from clinical specimens, the appropriate antibiotic therapy to infection with Desulfovibrio spp. has not been determined. We report the first case of liver abscess with bacteremia due to Desulfovibrio desulfuricans to show the clinical presentation and treatment. The patient was successfully treated with intravenous piperacillin-tazobactam and oral amoxicillin-clavulanic acid. PMID:25632357

    The genus Ruminococcus which are anaerobe Gram positive cocci, previously classified as Peptostreptococcus, may colonize the upper respiratory tract, gastrointestinal tract, vagina and skin of humans and animals. In this report a case of liver abscess and a case of infective endocarditis caused by Ruminoccocus productus, which is very rarely encountered in the clinical practice were presented. The first case was a 32 years old male who was admitted to the hospital in 2002, with the complaints of fever lasting for 20 days and pain while breathing. The abdominal ultrasonography revealed the presence of a liver abscess, and the drainage material from the abscess yielded Ruminococcus productus, identified in BACTEC 9200 (Becton Dickinson, Sparks, Md) anaerobe system. As the isolate was found to be sensitive to penicilin, the empirical gentamicin and ampicillin/sulbactam therapy was continued. The second case was a 25 years old male who was admitted to the hospital in 2005, with the signs of fever lasting for 3-4 months, chills, bone and joint pains. As multiple vegetations were detected in echocardiography, blood cultures were collected and empirical therapy with ceftriaxone and gentamicin was initiated with the preliminary diagnosis of infective endocarditis. Bacteria which were isolated from blood cultures by BACTEC 9200 system have been identified as R. productus. As this strain was also sensitive to penicillin, the empirical therapy was changed to penicilin and gentamicin. These two cases indicated that R. productus should be considered in complicated infections even if it is a rarely isolated species from the clinical samples. PMID:17205698

    A 69-year-old Caucasian man presented with fever, chills/rigors and night sweats since 6 days. Blood cultures (4/4) initially reported Gram negative lactose-fermenting rods. Physical examination was fairly benign which included a normal abdominal examination. Laboratory tests were significant for an elevated white cell count, erythrocyte sedimentation rate and C reactive protein . Empirically, he was treated with piperacillin tazobactam. A chart review showed that he had undergone a choledochojejunostomy for a pancreatic head tumour 7 years before. We found a few reported cases of hepatic abscesses after choledochojejunostomy presenting years after the procedure. An abdominal CT scan confirmed our suspicion. Percutaneous drainage was performed and his antibiotics were switched to ciprofloxacin and metronidazole, based on the sensitivity report. The patient's clinical condition steadily improved.

    The primitive abcess of psoas muscle is a rare affection which involves mainly the young. The authors report 18 cases of primitive pyogenic abcess of psoas collected during a period of six years in the urology service of UHC Ibn Rochd Casablanca. The purpose of this review is to discuss the different therapeutic attitudes. The study concerned 11 men and seven women, their mean age was 35 years. The mean delay of evolution was 45 days. The physical exam found a psoitisis (five cases) and a flunk swelling (14 cases). The ultrasound exam showed the collection which was hypoechogenic in seven cases and heterogenous in 11 cases. The CT scan showed an heterogenouse hypodense collection without enhansment in seven cases. The use of antibiotherapy alone (four cases) and percutaneous drainage (four cases) permitted the recovery just respectively in one and two cases. Fifteen patients (83%) were operated through a postero-lateral lumbotomy route without costal resection. The bacteriological exam of the pus found a Staphylococcis aureus (ten cases) and Escherichia coli (two cases). The evolution was favorable in 14 cases; one patient was dead at fifth day post operatively by heart infarction. For the authors, the surgical drainage remains the treatment of choice. PMID:11774765

    A 74-year-old man was referred to our hospital because of a high fever. He had undergone a dental extraction about 1 month prior to admission because of apical periodontitis. Imaging study revealed liver abscess lesions. Infection with Streptococcus anginosus was confirmed using both stab and blood culture. An adequate selection of antibiotics was administered, and a good outcome was obtained. There have been no case reports of liver abscess caused by intraoral commensal flora related to dental extraction in healthy adults. This case shows that liver abscesses can occur secondary to dental extractions, even in healthy adults. PMID:26250133

    Patient: Male, 66 Final Diagnosis: Toxic myocarditis Symptoms: — Medication: — Clinical Procedure: Emergency Specialty: Cardiology Objective: Rare disease Background: Chills, high fever, right upper abdomen pain, and increased white blood cell count are the main and common clinical features of bacterial liver abscess. It is rare to see bacterial liver abscess present symptoms of myocardial injury first, and this can lead to misdiagnosis. Case Report: We report a case of toxic myocarditis caused by bacterial liver abscess. The patient first presented with chest pain, ST segment elevation, and elevated TNI, which misled us to diagnose myocardial infarction, but the coronary artery had no stenosis or obstructive lesions after emergency coronary angiography. Then we modified the diagnosis to toxic myocarditis. Bacterial liver abscess was the proposed etiology after a series of auxiliary examinations. Finally, antibiotics and percutaneous liver puncture catheter drainage were used to improve the clinical outcome. Conclusions: It is rare that patients with bacterial liver abscess first present symptoms of myocardial injury. Differential diagnosis between myocarditis and myocardial infarction should be careful, as myocarditis is a diagnosis of exclusion, and coronary angiography is necessary to confirm coronary disease. Percutaneous liver puncture catheter drainage can effectively cure bacterial liver abscess. PMID:26726772

    Objectives: Pyogenic liver abscess (PLA) is a rare but potentially lethal infectious complication after radical surgical resection of hilar cholangiocarcinoma (HC), this study is aimed to identify the risk factors, management and prognosis of PLA after curative surgical resection of HC. Methods: Between January 2003 and October 2013, 95 patients who underwent surgical resection of HC at a tertiary center were included in this study. The risk factors pertaining to PLA formation were identified by exact logistic regression. Results: PLA developed in 8 of 95 patients. The median duration of PLA formation following surgical procedure was 145 days (range, 16-295 days) and the most commonly isolated microorganism was Escherichia coli (4/8). Though most patients who developed PLA after surgery were successfully managed with antibiotics and invasive therapy, the overall survival was statistically poorer than those without PLA formation (median, 16.9 vs. 34.2 months, P=0.048). Univariate analysis revealed that coexisting biliary disorders (37.5% vs. 8.0%, P=0.036), vascular reconstruction (37.5% vs. 9.2%, P=0.041) and margin status (62.5% vs. 21.8%, P=0.023) were associated with PLA formation, whereas only vascular reconstruction (odds ratio (OR), 10.31; 95% confidence interval (CI), 1.03-142.73; P=0.047) and margin status (OR, 8.45; 95% CI, 1.13-109.38; P=0.035) were identified as independent risk factors by multivariate analysis. Conclusions: Intraoperative vascular reconstruction and positive margin status pose greater risks for PLA formation after radical resection of HC. For patients with high risk factors, careful follow-up is needed for early detection and management of this infrequent complication. PMID:26885067

    Hepatic abscesses are potentially lethal diseases if early diagnosis and treatment are not instituted. They are prevalent all over the globe and pyogenic abscesses are predominant over amoebic. With better control of intra abdominal and systemic infections by a spectrum of antibiotics, aetiology of pyogenic abscesses are secondary to interventions and diseases in the biliary tree to a large extent today. The common organisms isolated are the Gram negative group. Amoebic abscesses continue to plague some regions of the world where hygiene and sanitation are questionable. Over the years, diagnosis, treatment and prognosis have evolved remarkably. Imaging modalities like ultrasonography and CT scan have become the cornerstone of diagnosis. The absence of ionizing radiation makes MRI an attractive alternative in patients who require multiple follow up scans. Serological testing in amoebic abscesses has become more reliable. Though antibiotics have remained the principal modality of management, percutaneous drainage of abscesses have vastly improved the chances of cure and bring down the morbidity drastically in pyogenic abscesses. Amoebic abscesses respond well to medical treatment with nitroimidazoles, and minimally invasive surgical drainage is an option in cases where open surgery is indicated. PMID:24532886

    A 48-year-old man with an unremarkable medical history was admitted with vague conditions of fever, chills, myalgias and malaise. Physical examination was remarkable for only scleral icterus. Laboratory evaluation revealed elevated aminotransferases, alkaline phosphatase and bilirubin. Imaging demonstrated two masses in the right lobe of his liver, which were ultimately drained and cultures demonstrated Actinomyces and Eikenella. He continued to have fever on broad-spectrum antibiotics until catheter drainage of the abscesses was performed. He was eventually discharged in improved condition on amoxicillin-clavulanate. His aminotransferases, alkaline phosphatase and bilirubin continued to improve and he remained afebrile and asymptomatic. A repeat CT 2 months after discharge demonstrated resolution of the abscesses. Actinomyces and Eikenella are rare causes of liver abscesses and treatment requires drainage and an extended course of antibiotics. The polymicrobial character typical of liver abscesses makes antibiotic therapy challenging when cultures reveal rare organisms such as Actinomyces and Eikenella. PMID:23867879

    We report a rare case of Klebsiella pneumoniae meningitis associated with liver abscess, which was successfully treated with cefotaxime (CTX), one of the third-generation cephalosporins. A 53-year-old man was admitted to Keio University Hospital on June 13, 1988, because of a fever and a headache. On June 3, he suddenly started shivering and his temperature rose to 39 degrees C. He then began to complain of polydipsia, polyuria, and a weight loss of 4 kg a week. On June 11, he developed a severe headache. Four years prior to this incident, he had been diagnosed as having diabetes after a routine medical examination, but had neglected to undergo medical treatment. On admission, laboratory data showed leukocytosis, hyperglycemia (394 mg/dl) and ketonuria (4+). A lumbar puncture yielded cloudy cerebrospinal fluid (CSF) containing 500/3 cells/mm8, of which about 70% were neutrophils. A diagnosis of diabetic ketoacidosis and purulent meningitis was made. A treatment with ampicillin (ABPC) and CTX, (12 g/day, each) was begun. On the third day, cultures of a blood specimen and CSF yielded both K. pneumoniae. The MICs of CTX to K. pneumoniae isolated from blood and CSF were both 0.05 microgram/ml. ABPC was discontinued, gentamicin was administered for 2 days, CTX was continued at the same dosage level and an administration of prednisolone 40 mg daily was begun.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2691713

    Amebic liver abscess (ALA) is endemic in developing countries. The epidemiology and clinical characteristics of the disease in developing countries are well described. Travelers from nonendemic countries can serve as a model for the natural history of ALA. Currently, the available literature on travelers is limited. This is a retrospective observational study on Israeli travelers diagnosed with ALA. Data regarding travel history, clinical presentation, imaging, and treatment were collected and analyzed. Among 6,867 ill returning Israeli travelers, amebiasis was diagnosed in 53 travelers (0.77%), of whom 14 were with ALA (0.2%). Twelve ALA cases (86%) had an exposure in the Indian subcontinent. The male to female ratio was 1:1, with no significant clinical differences between the sexes. The average lag period between exposure and onset of symptoms was 17.1 months. The lack of male predominance and the prolonged lag period may imply that behavioral factors are pivotal in the development of ALA. Larger case series of travelers are required. PMID:26928829

    Amebic liver abscess (ALA) is a serious, but readily treatable form of hepatic infection. In order to understand the clinical features of this condition in the United States, we reviewed the medical histories of 56 patients with ALA at two large San Francisco Hospitals from 1979 to 1994. Patients were divided into the following groups based on the presumed manner in which they had acquired ALA: those born or raised in the United States, with a history of travel to an endemic area (Tr-ALA); those from an endemic area, but living in the United States for less than one year (En-ALA); and those neither from nor having traveled to an endemic area (N-ALA). We found distinct clinical patterns in patients from different epidemiological groups. Patients with Tr-ALA were a decade older than those from endemic regions, were more likely to be male, and tended to have an insidious onset. Furthermore, compared to patients with En-ALA, those with Tr-ALA were more likely to have hepatomegaly (P < 0.0001) and large abscesses (ALA > 10 cm; P < 0.01). One third of the patients studied had no associated travel history or endemic origin as risk factors. Of these, 63% had a condition consistent with severe immunosuppression, such as infection with the human immunodeficiency virus (HIV), malnourishment with severe hypoalbuminemia, or chronic infection. In patients with N-ALA, the presence of a presumed immunosuppressed state increased significantly, as compared to patients with endemic or travel risk factors for ALA. During the last five years of the study, one third of all patients diagnosed with ALA were HIV positive (including 2 with a new diagnosis of AIDS), many of whom were discovered to be HIV-infected only after presentation with ALA. We conclude that travel to and origin in an endemic area are important risk factors for the development of ALA, and patients in these different epidemiological groups appear to have distinct clinical features. Further, in the absence of recognized

    Chronic granulomatous disease (CGD) is a rare inherited disorder caused by defective nicotinamide adenine dinucleotide phosphate oxidase enzyme and characterized by recurrent bacterial and fungal infections. Although liver abscess is a common manifestation of CGD, its management in CGD patients is not well-defined. In addition, the generalized guidelines for treating liver abscesses do not necessarily apply to CGD patients. Corticosteroids are commonly used to control granulomatous complications, such as inflammatory gastrointestinal and genitourinary lesions, in patients with CGD, Corticosteroids have also been used in combination with antimicrobials to treat refractory infections in patients with CGD. Because corticosteroids are capable of suppressing symptomatic inflammation, all potential infections must be adequately controlled prior to corticosteroid initiation. We report 3 typical CGD cases with liver abscesses refractory to conventional treatments that were successfully treated with the concomitant use of corticosteroid and antimicrobials. It remains unclear whether corticosteroid therapy is required for liver abscesses in CGD refractory to conventional treatments. However, based on our observations, use of corticosteroids in combination with optimal antimicrobials should be considered for refractory liver abscesses in CGD. PMID:27186231

    A 72-year-old man consulted in November 2012 for abdominal pain in the right upper quadrant. The patient had a history of suspected hepatic amebiasis treated in Senegal in 1985 and has not traveled to endemic areas since 1990. Abdominal CT scan revealed a liver abscess. At first, no parasitological tests were performed and the patient was treated with broad-spectrum antibiotics. Only after failure of this therapy, serology and PCR performed after liver abscess puncture established the diagnosis of hepatic amebiasis. The patient was treated with metronidazole and tiliquinol-tilbroquinol. Amebic liver abscess is the most frequent extra-intestinal manifestation. Hepatic amebiasis 22 years after the last visit to an endemic area is exceptional and raises questions on the mechanisms of latency and recurrence of these intestinal protozoan parasites.

    Seven definite and three probable cases of pyogenic sacroiliitis are presented and compared to 72 cases found in the English literature. Patients may present with a subacute localized or an acute systemic illness. Six of our patients were parenteral drug abusers. Sacroiliac uptake of gallium 67 citrate and/or technetium 99m pyrophosphate suggested the diagnosis which was confirmed by fluoroscopically controlled joint aspiration when blood cultures were sterile. Gram-negative organisms, group B streptococci and a Staphylococcus were isolated. Antibiotic treatment for four to six weeks was uniformly successful. Surgery should be reserved for abscess or sequestrum formation, neither of which were encountered in this series.

    A 43-year-old man was admitted to our hospital because of an abnormal shadow on chest X-ray. Blood testing showed elevated levels of C-reactive protein and white blood cells. Computed tomography revealed multilocular masses of the right hepatic lobe, reticulonodular shadowing on both lungs, left kidney masses, and aortic arch aneurysm. Fusobacterium nucleatum was isolated from the hepatic abscess after percutaneous transhepatic drainage. Because of severe dental caries, he was diagnosed with liver abscess caused by dental infection with F. nucleatum. Administration of cefmetazole and meropenem was not effective; however, he showed remarkable improvement after treatment with metronidazole and continuous drainage. PMID:27151479

    Amebiasis, infection with the protozoan Entamoeba histolytica, affects at least 10% of the world's population, with an incidence exceeding 30% in tropical and subtropical regions. Amebic liver abscess (ALA) is the most common extraintestinal form of invasive amebiasis and is a serious life-threatening disease in children. Recent experience indicates the prognosis of ALA in childhood to be improved with early identification of abscesses and prompt institution of treatment. The authors incorporate experience with a case of ALA in infancy with a review of current literature (1974-1983) to delineate clinical and radiologic features of ALA in childhood and further define the role of hepatic imaging in the diagnosis and treatment.

    PurposePatients without a competent sphincter of Oddi due to prior surgical or endoscopic therapy are at high risk for liver abscess following chemoembolization despite aggressive antimicrobial prophylaxis. We examined a cohort of such patients undergoing Y-90 resin radioembolization and compared them to a cohort of chemoembolized patients.MethodsReview of our quality-assurance database identified 24 radioembolizations performed in 16 patients with prior biliary intervention. An aggressive prophylactic regimen of oral levofloxacin and metronidazole 2 days pre-procedure continuing for 14 days after, oral neomycin/erythromycin bowel prep the day before, and IV levofloxacin/metronidazole the day of treatment was prescribed. Patients underwent resin microsphere radioembolization dosed according to the BSA method. Patients had clinical, imaging, and laboratory assessment 1 month after each treatment, and then every 3 months. The chemoembolization cohort consisted of 13 patients with prior biliary intervention who had undergone 24 chemoembolization procedures.ResultsNo radioembolization patient developed an abscess. In the cohort of chemoembolized patients who received the same prophylaxis, liver abscess occurred following 3 of 24 (12.5 %) procedures in 3 of 13 (23 %) patients, one fatal.ConclusionsThis preliminary experience suggests that the risk of liver abscess among patients with prior biliary intervention may be lower following radioembolization than chemoembolization, which could potentially expand treatment options in this high-risk population.

  11. Amoebic liver abscess – a cause of acute respiratory distress in an infant: a case report

    2009-01-01

    Introduction The usual presentation of amebic liver abscess in children is extremely variable and unpredictable. It presents with a picture of common pediatric illness that is fever, lethargy, and abdominal pain, and can go on to develop into a rare complication of rupture into the pleura to cause acute respiratory distress, which is another common pediatric illness. In our patient, diagnosis was not made or suspected in these two stages. Case presentation This is the report of a 2-year-old male infant who presented with a 2-week history of anorexia, fever, and abdominal pain. A few hours after admission, he suddenly developed acute respiratory distress; chest X-ray demonstrated massive right pleural effusion that failed to response to tube thoracostomy. Limited thoracotomy revealed a ruptured amebic liver abscess through the right cupola of the diaphragm. The content of the abscess was evacuated from the pleural cavity, which was drained with two large chest tubes. Serological examination confirmed the diagnosis of ruptured amebic liver abscess. Postoperative treatment with antibiotics including metronidazole continued until full recovery. Conclusion Diagnosis of such a rare disease requires a high degree of suspicion. In this patient, the diagnosis was only made postoperatively. The delay in presentation and the sudden onset of respiratory distress must be emphasized for all those physicians who care for children.

    Various hepato-biliary complications are an increased incidence in patients with inflammatory bowel disease, and portal bacteremia is well documented in patients with ulcerative colitis (UC). However, few reports mention UC in association with liver abscesses. Recently, there are several reports describing cytomegalovirus (CMV) infection in association with disease exacerbation and steroid refractoriness in patients with UC. Here we present a case of refractory UC accompanied with multiple liver abscesses and CMV colitis. The patient, a 72-year-old male, with a five-year history of repeated admissions to our hospital for UC, presented with an exacerbation of his UC. Sigmoidoscopy performed on admission suggested that his UC was exacerbated, then he was given prednisolone and mesalazine orally, and betamethasone enemas. However, he had exacerbated symptoms. Repeat sigmoidoscopy revealed multiple longitudinal ulcers and pseudopolyps in the rectosigmoid colon. Although immunohistochemical staining of biopsy specimens and the serum testing for antigenemia were negative on admission and after the repeat sigmoidoscopy, they became histologically positive for CMV. Nonetheless, the patient developed spiking fevers, soon after ganciclovir was administered. Laboratory studies revealed an increased white cell count with left shift, and Enterococcus fecalis grew in blood cultures. An abdominal computed tomography (CT) scan was obtained and the diagnosis of liver abscesses associated with UC was made, based on CT results. The hepatic abscesses were successfully treated with intravenous meropenem for 6 wk, without further percutaneous drainage. To our knowledge, this is the first reported case of multiple liver abscesses that develop during UC exacerbation complicated by CMV colitis. PMID:16127763

    Fascioliasis is an endemic zoonotic disease in Iran. It occurs mainly in sheep-rearing areas of temperate climates, but sporadic cases have been reported from many other parts of the world. The usual definitive host is the sheep. Humans are accidental hosts in the life cycle of Fasciola. Typical symptoms may be associated with fascioliasis, but in some cases diagnosis and treatment may be preceded by a long period of abdominal pain and vague gastrointestinal symptoms. We report a case with epigastric and upper quadrant abdominal pain for the last 6 months, with imaging suggesting liver abscess and normal biliary ducts. The patient had no eosinophilia with negative stool examinations, so she was initially treated with antibiotics for liver abscess. Her clinical condition as well as follow-up imagings showed appropriate response after antibiotic therapy. Finally, endoscopic ultrasonography revealed Fasciola hepatica, which was then extracted with endoscopic retrograde cholangiopancreatography. PMID:25473389

    Amebic liver abscess (ALA) is the most common extraintestinal manifestation of human infection by the enteric protozoan parasite Entamoeba histolytica. In contrast to intestinal infection, ALA greatly predominates in males but is rare in females. Since humans are the only relevant host for E. histolytica, experimental studies concerning this sexual dimorphism have been hampered by the lack of a suitable animal model. By serial liver passage of cultured E. histolytica trophozoites in gerbils and mice, we generated amebae which reproducibly induce ALA in C57BL/6 mice. Interestingly, all animals developed ALA, but the time courses of abscess formation differed significantly between the genders. Female mice were able to clear the infection within 3 days, whereas in male mice the parasite could be recovered for at least 14 days. Accordingly, male mice showed a prolonged time of recovery from ALA. Immunohistology of abscesses revealed that polymorphonuclear leukocytes and macrophages were the dominant infiltrates, but in addition, γ,δ-T cells, NK cells, and natural killer T (NKT) cells were also present at early times during abscess development, whereas conventional α,β-T cells appeared later, when female mice had already cleared the parasite. Interestingly, male and female mice differed in early cytokine production in response to ameba infection. Enzyme-linked immunospot assays performed with spleen cells of infected animals revealed significantly higher numbers of interleukin-4-producing cells in male mice but significantly higher numbers of gamma interferon (IFN-γ)-producing cells in female mice. Early IFN-γ production and the presence of functional NKT cells were found to be important for the control of hepatic amebiasis as application of an IFN-γ-neutralizing monoclonal antibody or the use of NKT knockout mice (Vα14iNKT, Jα 18−/−) dramatically increased the size of ALA in female mice.

TVGHKP93 retained its high virulence compared with that of the isogenic strain (TVGHKP60) with wild-type resistance from the first liver abscess. Our conjugation experiment showed the successful transfer of the blaCMY-2-carrying plasmid from TVGHEC01 into TVGHKP60. The transconjugant showed both high virulence and the multidrug-resistant phenotype, as did TVGHKP93. PMID:25987637

    Amebiasis, infection by the intestinal protozoan parasite Entamoeba histolytica, is a leading parasitic cause of death. As a step in the development of a recombinant antigen vaccine to prevent E. histolytica infection, we looked at the ability of a recombinant version of the serine-rich E. histolytica protein (SREHP) to elicit a protective immune response against invasive amebic disease. Gerbils, a standard model for amebic liver abscess, were immunized with either a recombinant SREHP/maltose-binding protein (MBP) fusion, recombinant MBP alone, or phosphate-buffered saline (PBS), all combined with complete Freund's adjuvant. In the first trial (group 1), gerbils received a primary and two booster immunizations intraperitoneally; in the second trial (group 2), gerbils were immunized by a single intradermal injection. SREHP/MBP-immunized gerbils in both groups produced antibody to native SHEHP and developed delayed-type hypersensitivity responses to recombinant SREHP. All gerbils were challenged by an intrahepatic injection with 5 x 10(4) virulent E. histolytica HM1-IMSS trophozoites. Complete protection from amebic liver abscess was seen in 64% of the SHEHP/MBP-immunized gerbils in group 1 and in 100% of the SREHP/MBP-immunized gerbils in group 2. There was no protection observed in MBP- or PBS-immunized gerbils in either group. Our results indicate that the SREHP molecule has potential as a vaccine to prevent amebic infection and demonstrate that successful vaccination of animals with recombinant E. histolytica antigen vaccines is possible.

    Invasive cerebral aspergillosis always developed in immunocompromised host. Early diagnosis may save life in this critical condition; however, it is difficult to reach. Herein, we presented an unusual case of invasive cerebral aspergillosis in a cirrhotic patient. A 47-year-old man presented with progressive deterioration of consciousness for three days. The patient had a history of alcoholic liver cirrhosis, Child-Pugh class C. Magnetic resonance imaging (MRI) of brain showed multi-focal parenchymal lesions, which was consistent with multiple brain abscesses. The diagnosis of invasive cerebral aspergillosis was made by molecular based laboratory methods including Aspergillus galactomannan antigen assay and oligonucleotide array. Despite treatment with the antifungal agent, Amphotericin B, the patient died at the ninth day of hospitalization. Our findings suggest that liver cirrhosis can be one of risk factors of invasive cerebral aspergillosis, and support the diagnosing usefulness of MRI, Aspergillus galactomannan antigen assay, and oligonucleotide array.

    Abstract The worldwide incidence of Klebsiella pneumoniae liver abscess (KLA) is increasing. It is important to accurately diagnose this life-threatening disease to provide timely and appropriate treatment. Here we report the case of a 38-year-old man with acute renal failure and a tumor-like liver abscess and septic pulmonary embolism. Initially, his clinical symptoms, laboratory tests, and radiological findings presented equivocal results of malignancy with metastases. Fine needle aspiration of liver tumor was performed, which showed purulent material with a culture positive for K pneumoniae. KLA symptoms are atypical, and radiological findings may mimic a malignancy with tumor necrosis. In some circumstances, liver aspiration biopsy may be necessary to confirm the real etiology, leading to prompt and timely treatment. Moreover, we should be alert for the impression of KLA when facing a diabetic patient with liver mass lesion and acute renal failure. PMID:26986170

    Hepatic abscess caused by foreign body penetration of the alimentary tract is rare. We report a case of gastric antrum penetration due to a toothpick complicated by liver abscess formation. A 41-year-old man was admitted to our hospital with the chief complaint of upper abdominal pain for 2 mo. Esophagogastroduodenoscopy performed at a local clinic revealed a toothpick penetrating the gastric antrum. Computed tomography (CT) of the abdomen at our hospital revealed a gastric foreign body embedded in the posterior wall of gastric antrum with regional phlegmon over the lesser sac and adhesion to the pancreatic body without notable vascular injury, and a hepatic abscess seven cm in diameter over the left liver lobe. Endoscopic removal of the foreign body was successfully performed without complication. The liver abscess was treated with parenteral antibiotics without drainage. The patient’s recovery was uneventful. Abdominal ultrasonography demonstrated complete resolution of the hepatic abscess six months after discharge. Relevant literature from the PubMed database was reviewed and the clinical presentations, diagnostic modalities, treatment strategies and outcomes of 88 reported cases were analyzed. The results showed that only 6 patients received conservative treatment with parenteral antibiotics, while the majority underwent either image-guided abscess drainage or laparotomy. Patients receiving abscess drainage via laparotomy had a significantly shorter length of hospitalization compared with those undergoing image-guided drainage. There was no significant difference in age between those who survived and those who died, however, the latter presented to hospitals in a more critical condition than the former. The overall mortality rate was 7.95%. PMID:24707157

    Liver abscesses are the primary liver abnormality of feedlot cattle at slaughter. The incidence of liver abscesses is highly variable, but generally ranges from 10% to 20%. The incidence of total and the proportion of severely abscessed livers (A+) are greater in Holsteins fed for beef production and culled dairy cows than in beef breeds. The reason for the greater incidence of liver abscesses in Holstein steers is not known, but one of the reasons is likely because of increased days on feed. The high prevalence in cull cows is likely because no specific intervention, such as use of tylosin in the feed, is approved for use in dairy cows. Liver abscesses are generally a sequela to ruminal acidosis and rumenitis in cattle fed diets high in readily-fermentable carbohydrates and low in roughages; thus, the term "acidosis-rumenitis-liver abscess complex." Liver abscesses are almost always polymicrobial infections with Gram negative anaerobes constituting the predominant flora. Almost all studies have concluded that , a ruminal bacterium, is the primary causative agent and (formerly ) is the secondary pathogen. A limited number of studies have been done on the bacterial flora of liver abscesses of culled dairy cows and Holstein feedlot steers. A recent study has reported on isolation of from liver abscesses of Holstein cattle. The control of liver abscesses in feedlot cattle has depended on the use of antibiotics, particularly tylosin, in the feed combined with sound nutritional management to minimize occurrence of acidosis and subsequent rumenitis. Although there is no evidence of resistance development in , the future of tylosin use as a feed additive in feedlot cattle is uncertain. Regardless, beginning January 2017, the use of tylosin in feedlot cattle for the prevention of liver abscesses will be under veterinary oversight. Although tylosin is widely used in the feedlot industry, there is considerable interest in evaluating antibiotic alternatives, such as essential

    Using combined Tc-99m sulfur colloid and In-113m chloride eluate imaging, studies from 32 patients with proven amebic liver abscess were analyzed. The results revealed good perfusion of the amebic lesion in three, poor perfusion in 11, and absent perfusion in 18. These results appear to depend on abscess size and age. Images with In-113m seem to be better than those with Tc-99m sulfur colloid in depicting amebic liver abscess during antiamebic therapy. Overall, the In-113m images provide more precise information concerning abscess size and shape.

    The authors deal with the problem of application of a therapeutic fine needle aspiration puncture in abscesses and other purulent foci in organs of abdominal cavity and retroperitoneum. The treatment using this method under continuing antibiotic therapy has been used in 60 patients (40 men, 20 women), 25 of them suffering from liver abscesses, 28 other from purulent foci of pancreas and seven patients from purulent foci of the kidney. In most patients there were solitary foci (43 persons). The total volume of the evacuated pus was higher than 20 ml in most patients (52), being even more than 100 ml in 2 patients. No relation ship was found among the number of foci, their volume and efficiency of the treatment. The average number of punctures until the abscesses and other purulent foci were healed up was 2.76 in the liver, 2.5 in pancreas and 1.1 in the kidney. The efficiency of therapy was higher in liver abscesses (96%), in purulent foci of pancreas (82%) and lower in the kidney abscesses (57%). The higher efficiency in the purulent foci of pancreas was probably influenced by predominant representation by infected pseudocysts in this group. The lower average number of punctures until the abscesses were healed up and the lower success in the kidney were influenced by a more radical approach of urologists who, having made the first evacuation puncture, performed a radical operation intervention. The complications were encountered in 9.5% of all punctures, being always insignificant. The results obtained demonstrated the contribution of aimed therapeutic aspiration puncture in the therapy of purulent foci of parenchymal organs of abdominal cavity and retroperitoneum as compared with surgical treatment. The advantage of the applied method in the therapy of purulent foci of the liver and pancreas may be seen in the higher success rate, low invasiveness and a low risk of complications together with a low financial cost and wide availability.

    Hepatic arterial flow is paramount in preserving biliary integrity. We present an interesting clinical scenario of a liver transplant recipient with biliary anastomotic stricture who developed biliary abscess and sepsis after Endoscopic Retrograde Cholangiopancreatography. The abscess did not respond to maximal medical management, percutaneous drainage, and adequate endoscopic biliary drainage. Clinically, patient continued to deteriorate and imaging identified hepatic artery stenosis which was treated with percutaneous intra-arterial stenting. Revascularization and perfusion of infected area led to rapid resolution of abscess and sepsis. This case emphasizes the anatomic basis of biliary ductal pathology. An important educational point is to understand that interrupted hepatic arterial supply can lead to biliary complications in liver transplant recipients and early correction of perfusion deficit should be pursued in such cases. In nonresolving hepatobiliary infections after liver transplantation, hepatic arterial compromise should be looked for and if present promptly treated. Reperfusion of biliary system in our patient led to improved antibiotics penetration, resolution of abscess and sepsis, and healing of biliary stricture. PMID:27340588

    Streptococcus pyogenes, a common pathogen of humans, was isolated from the carcass of a free-living European hedgehog (Erinaceus europaeus) found in northern England in June 2014. The animal had abscessation of the deep right cervical lymph node, mesenteric lymph nodes and liver. The S. pyogenes strain isolated from the lesions, peritoneal and pleural cavities was characterised as emm 28, which can be associated with invasive disease in humans. This is the first known report of S. pyogenes in a hedgehog and in any free-living wild animal that has been confirmed by gene sequencing. As close associations between wild hedgehogs and people in England are common, we hypothesise that this case might have resulted from anthroponotic infection. PMID:26242215

    Arcanobacterium pyogenes, a commensal on the mucous membranes of many economically important animal species, is also a pathogen, causing abscesses of the skin, joints, and visceral organs as well as mastitis and abortion. In food animals, A. pyogenes is exposed to antimicrobial agents used for growth promotion, prophylaxis, and therapy, notably tylosin, a macrolide antibiotic used extensively for the prevention of liver abscessation in feedlot cattle in the United States. Of 48 A. pyogenes isolates, 11 (22.9%) exhibited inducible or constitutive resistance to tylosin (MIC of > or = 128 microg/ml). These isolates also exhibited resistance to other macrolide and lincosamide antibiotics, suggesting a macrolide-lincosamide resistance phenotype. Of the 11 resistant isolates, genomic DNA from nine hybridized to an erm(X)-specific probe. Cloning and nucleotide sequencing of the A. pyogenes erm(X) gene indicated that it was >95% similar to erm(X) genes from Corynebacterium and Propionibacterium spp. Eight of the erm(X)-containing A. pyogenes isolates exhibited inducible tylosin resistance, which was consistent with the presence of a putative leader peptide upstream of the erm(X) open reading frame. For at least one A. pyogenes isolate, 98-4277-2, erm(X) was present on a plasmid, pAP2, and was associated with the insertion sequence IS6100. pAP2 also carried genes encoding the repressor-regulated tetracycline efflux system determinant Tet 33. The repA gene from pAP2 was nonfunctional in Escherichia coli and at least one A. pyogenes isolate, suggesting that there may be host-encoded factors required for replication of this plasmid.

    Saliva is an easily-accessible and a non-invasive clinical specimen alternate to blood and liver pus. An attempt was made to detect Entamoeba histolytica DNA released in the saliva of amoebic liver abscess (ALA) patients by applying 16S-like rRNA gene-based nested multiplex polymerase chain reaction (NM-PCR). The NM-PCR detected E. histolytica DNA in the saliva of eight (28.6%) of 28 ALA patients. The NM-PCR result was negative for E. histolytica DNA in the saliva of all the eight ALA patients who were tested prior to treatment with metronidazole but was positive in the saliva of eight (40%) of 20 ALA patient who were tested after therapy with metronidazole. The NM-PCR detected E. histolytica DNA in liver abscess pus of all 28 (100%) patients with ALA. The TechLab E. histolytica II enzyme-linked immunosorbent assay was positive for E. histolytica Gal/GalNAc lectin antigen in the liver abscess pus of 13 (46.4%) of the 28 ALA patients. The indirect haemagglutination (IHA) test was positive for anti-amoebic antibodies in the serum of 22 (78.6%) of the 28 ALA patients and 2 (5.7%) of 35 healthy controls. The present study, for the first time, demonstrates the release of E. histolytica DNA in the saliva of ALA patients by applying NM-PCR. PMID:19069620

    Nocardia thyroid abscess with pneumonia is a rare clinical presentation. We reported a liver transplant recipient with Nocardia thyroiditis and pneumonia after receiving high dose immunosuppressants to preserve his graft. The patient is a 50-year-old male who developed hepatitis C virus-related liver cirrhosis and received a liver transplant. Seven months post-transplantation the patient developed graft rejection, which was treated with 3 days pulse dose methyl-prednisolone followed by an increased dose of his tracolimus, mycophenolate and prednisolone. He presented to the hospital with a 2 week history of fever, tenderness in his anterior neck and dry cough. On admission his temperature was 39.5°C. The right wing of his thyroid gland was swollen to 3 cm in size, fluctuant and tender. On auscultation of his lungs there were fine crepitations and increased vocal resonance in the right middle lung field. On laboratory testing, a complete blood count (CBC) revealed leukocytosis (19,900/mm3) with neutrophils (97%). A chest X-ray showed an patchy infiltrates and round circumscribed densities in the superior segment of the right lower lobe of his lung. A CT scan of his neck revealed a diffusely enlarged right wing of the thyroid gland, 3.8 cm in diameter that had an abnormal hyposignal area. A CT of his chest revealed consolidation of the superior segment of the right lower lobe and necrotic right paratracheal lymph nodes with inflamed strap muscles. Fine needle aspiration of the right lobe of thyroid gland was performed. Modified acid-fast bacilli (MAFB) staining showed partially acid-fast beaded branching filamentous organisms and a culture grew out Nocardia asteroides. He was treated with trimethoprim-sulfamethoxazole for 6 months. He improved clinically and his chest X-ray also cleared. PMID:26867364

    Pyogenic haematogenous cervical epidural abscess complicated by tetraplegia is an uncommon entity, but its clinical importance overshadows its rarity. Predisposing risk factors for spinal epidural abscess include diabetes, intravenous drug abuse, liver disease, renal failure, malignancy, HIV, infection elsewhere, rheumatoid conditions, trauma and a number of spinal interventions. Lack of recovery and death are much more frequent when complete paralysis exists since more than 24 to 48 hours. Most authors combine decompressive laminectomy and antibiotics. Anterior decompression and needle aspiration are rarely used, the former more specifically in case of anterior abscess formation. A high index of suspicion along with reliance on gadolinium-enhanced MRI is essential to diagnose the pathology and institute appropriate treatment on an individual basis. The authors report on a diabetic male patient who developed a cervical epidural abscess with tetraplegia after dental extraction. He was treated within six hours by one stage anterior/posterior decompression and fusion, with complete recovery. PMID:21954768

    Host invasion by Entamoeba histolytica, the pathogenic agent of amebiasis, can lead to the development of amebic liver abscess (ALA). Due to the difficulty of exploring host and amebic factors involved in the pathogenesis of ALA in humans, most studies have been conducted with animal models (e.g., mice, gerbils, and hamsters). Histopathological findings reveal that the chronic phase of ALA in humans corresponds to lytic or liquefactive necrosis, whereas in rodent models there is granulomatous inflammation. However, the use of animal models has provided important information on molecules and mechanisms of the host/parasite interaction. Hence, the present review discusses the possible role of neutrophils in the effector immune response in ALA in rodents. Properly activated neutrophils are probably successful in eliminating amebas through oxidative and non-oxidative mechanisms, including neutrophil degranulation, the generation of free radicals (O2(-), H2O2, HOCl) and peroxynitrite, the activation of NADPH-oxidase and myeloperoxidase (MPO) enzymes, and the formation of neutrophil extracellular traps (NETs). On the other hand, if amebas are not eliminated in the early stages of infection, they trigger a prolonged and exaggerated inflammatory response that apparently causes ALAs. Genetic differences in animals and humans are likely to be key to a successful host immune response. PMID:26880421

    Even in the absence of Amebic colitis, Amebic liver abscess (ALA) is the most common extraintestinal complication of Entamoeba histolytica infection. In the USA, it is most prevalent in middle aged immigrant males from endemic countries such as Africa, Mexico, and India. One of the complications of ALA is inferior vena cava (IVC) thrombosis, which is believed to result from the mechanical compression of the IVC and the consequent thrombogenic nidus elicited from the resultant inflammatory response. There are very few reported cases and even fewer in which the thrombus became a harbinger to pulmonary thromboembolism. We present the case of a 43-year-old male from West Africa who presented with the chief complaint of right upper quadrant abdominal pain for one week associated with persistent nonproductive cough. He had a positive serum Entamoeba histolytica antibody with CT scan findings of a hepatic abscess with thrombosis of the hepatic vein and inferior vena cava and numerous bilateral pulmonary emboli. This amebic liver abscess was successfully treated with metronidazole and paromomycin, whereas the pulmonary thromboembolism was managed with medical anticoagulation. Based on current knowledge, this is the first reported case in the USA. PMID:26294987

    The innate immune response is supposed to play an essential role in the control of amebic liver abscess (ALA), a severe form of invasive amoebiasis due to infection with the protozoan parasite Entamoeba histolytica. In a mouse model for the disease, we previously demonstrated that Jα18-/- mice, lacking invariant natural killer T (iNKT) cells, suffer from more severe abscess development. Here we show that the specific activation of iNKT cells using α-galactosylceramide (α-GalCer) induces a significant reduction in the sizes of ALA lesions, whereas CD1d−/− mice develop more severe abscesses. We identified a lipopeptidophosphoglycan from E. histolytica membranes (EhLPPG) as a possible natural NKT cell ligand and show that the purified phosphoinositol (PI) moiety of this molecule induces protective IFN-γ but not IL-4 production in NKT cells. The main component of EhLPPG responsible for NKT cell activation is a diacylated PI, (1-O-[(28∶0)-lyso-glycero-3-phosphatidyl-]2-O-(C16:0)-Ins). IFN-γ production by NKT cells requires the presence of CD1d and simultaneously TLR receptor signalling through MyD88 and secretion of IL-12. Similar to α-GalCer application, EhLPPG treatment significantly reduces the severity of ALA in ameba-infected mice. Our results suggest that EhLPPG is an amebic molecule that is important for the limitation of ALA development and may explain why the majority of E. histolytica-infected individuals do not develop amebic liver abscess.

We explored the distribution of Q223R mutation in leptin receptor gene of amoebic liver abscess (ALA) patients of North India. A total of 55 ALA samples along with 102 controls were subjected to PCR-RFLP analysis. The frequency of allele “G” (coding for arginine) was in general high in Indian population irrespective of the disease. Our results of Fisher exact test shows that heterozygous mutant (QQ versus QR, P = 0.049) and homozygous mutant (QQ versus RR, P = 0.004) were significantly associated with amoebic liver abscess when compared with homozygous wild (QQ).

    Amebic liver abscess (ALA), a parasitic disease due to infection with the protozoan Entamoeba histolytica, occurs age and gender dependent with strong preferences for adult males. Using a mouse model for ALA with a similar male bias for the disease, we have investigated the role of female and male sexual hormones and provide evidence for a strong contribution of testosterone. Removal of testosterone by orchiectomy significantly reduced sizes of abscesses in male mice, while substitution of testosterone increased development of ALA in female mice. Activation of natural killer T (NKT) cells, which are known to be important for the control of ALA, is influenced by testosterone. Specifically activated NKT cells isolated from female mice produce more IFNγ compared to NKT cells derived from male mice. This high level production of IFNγ in female derived NKT cells was inhibited by testosterone substitution, while the IFNγ production in male derived NKT cells was increased by orchiectomy. Gender dependent differences were not a result of differences in the total number of NKT cells, but a result of a higher activation potential for the CD4− NKT cell subpopulation in female mice. Taken together, we conclude that the hormone status of the host, in particular the testosterone level, determines susceptibility to ALA at least in a mouse model of the disease. PMID:23424637

    Introduction The Streptococcus anginosus group of bacteria are low-virulence bacteria existing as commensals in the oral flora and gastrointestinal tracts of humans. S. anginosus may spread to the blood in individuals with poor oral hygiene in cases of oral infections, such as gingivitis and tooth abscesses, that develop following the loss of mucosal unity. This may lead to infections in the whole body, primarily as brain and liver abscesses. Case Presentation A 32-year-old male patient presented with complaints of nausea, vomiting, and diffuse abdominal pain. Diffuse abdominal tenderness and rebound tenderness were detected particularly in the epigastrium and right upper quadrant. Laboratory assessment revealed a leukocyte count of 20,500/mm3. Free fluid around the liver and heterogeneous areas of abscess formation in the right lateral gallbladder were revealed on abdominal computed tomography. Diffuse adhesions between the bowel and seropurulent free liquid in the abdomen were detected on surgical exploration, and a sample was taken for cultures. The patient was discharged without complications on the sixth postoperative day and his antibiotic course was completed with 4 weeks of oral treatment. We reviewed the literature for similar cases of disseminated pyogenic infections caused by the S. anginosus group. Conclusions It should be kept in mind that the oral flora bacterium S. anginosus may cause transient bacteremia and deep-seated organ abscesses in immunodeficient patients with poor oral hygiene. Such patients with intra-abdominal abscesses should be treated with antibiotics and surgery.

    Background Entamoeba histolytica is an intestinal protozoan parasite that causes amoebiasis, including amebic dysentery and liver abscesses. E. histolytica invades host tissues by adhering onto cells and phagocytosing them depending on the adaptation and expression of pathogenic factors, including Gal/GalNAc lectin. We have previously reported that E. histolytica possesses multiple CXXC sequence motifs, with the intermediate subunit of Gal/GalNAc lectin (i.e., Igl) as a key factor affecting the amoeba's pathogenicity. The present work showed the effect of immunization with recombinant Igl on amebic liver abscess formation and the corresponding immunological properties. Methodology/Principal Findings A prokaryotic expression system was used to prepare the full-length Igl and the N-terminal, middle, and C-terminal fragments (C-Igl) of Igl. Vaccine efficacy was assessed by challenging hamsters with an intrahepatic injection of E. histolytica trophozoites. Hamsters intramuscularly immunized with full-length Igl and C-Igl were found to be 92% and 96% immune to liver abscess formation, respectively. Immune-response evaluation revealed that C-Igl can generate significant humoral immune responses, with high levels of antibodies in sera from immunized hamsters inhibiting 80% of trophozoites adherence to mammalian cells and inducing 80% more complement-mediated lysis of trophozoites compared with the control. C-Igl was further assessed for its cellular response by cytokine-gene qPCR analysis. The productions of IL-4 (8.4-fold) and IL-10 (2-fold) in the spleen cells of immunized hamsters were enhanced after in vitro stimulation. IL-4 expression was also supported by increased programmed cell death 1 ligand 1 gene. Conclusions/Significance Immunobiochemical characterization strongly suggests the potential of recombinant Igl, especially the C-terminal fragment, as a vaccine candidate against amoebiasis. Moreover, protection through Th2-cell participation enabled effective

    A novel cytotoxin (intermedilysin) specific for human cells was identified as a cytolytic factor of Streptococcus intermedius UNS46 isolated from a human liver abscess. Intermedilysin caused human cell death with membrane blebs. Intermedilysin was purified from UNS46 culture medium by means of gel filtration and hydrophobic chromatography. The purified toxin was resolved into major and minor bands of 54 and 53 kDa, respectively, by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. These proteins reacted with an antibody against intermedilysin. Five internal peptide fragments of intermedilysin were sequenced and found to have 42 to 71% homology with the thiol-activated cytotoxin pneumolysin. However, the action of intermedilysin differed from that of thiol-activated cytotoxins, especially in terms of a lack of activation by dithiothreitol and resistance to treatments with N-ethylmaleimide and 5,5'-dithio-bis-(2-nitrobenzoic acid), although cholesterol inhibited the toxin activity. Intermedilysin was potently hemolytic on human erythrocytes but was 100-fold less effective on chimpanzee and cynomolgus monkey erythrocytes. Intermedilysin was not hemolytic in nine other animal species tested. Since human erythrocytes treated with trypsin were far less sensitive to intermedilysin than were the intact cells, a cell membrane protein(s) may participate in the intermedilysin action. These data demonstrated that intermedilysin is distinguishable from all known bacterial cytolysins. PMID:8757839

    The Entamoeba histolytica EhCPADH complex, formed by a cysteine proteinase (EhCP112) and an adhesin (EhADH112), is involved in adherence, phagocytosis and cytolysis. This makes this complex an attractive candidate as a vaccine against amoebiasis. Here, we produced the recombinant polypeptide EhADH243, which includes the adherence epitope detected by a monoclonal antibody against the EhCPADH complex. EhADH243 was purified, and the effect of the polypeptide on in vitro and in vivo virulence was studied. Antibodies against EhADH243 reacted with the EhCPADH complex and with the recombinant polypeptide. EhADH243 and antibodies against this polypeptide inhibited adherence, phagocytosis and destruction of cell monolayers by live trophozoites, but had little effect on cell monolayer destruction by trophozoite extracts. EhADH243 recognized a 97 kDa protein in the MDCK membrane fraction that could be a putative receptor for E. histolytica trophozoites. Hamsters immunized with EhADH243 developed humoral response against EhCPADH, and animals were partially protected from amoebic liver abscess. PMID:15009028

    Patient: Male, 67 Final Diagnosis: Pancreatic abscess Symptoms: Jaundice • fatigue • anorexia • subjective weight loss Medication: — Clinical Procedure: Therapeutic endoscopic ultrasound guided fine needle aspiration • biliary stenting • endoscopic cholangiopancreatography Specialty: Gastroenterology and Hepatology Objective: Rare coexistance of disease or pathology Background: Pancreatic abscesses are rare. They may be seen in patients with pancreatic inflammation or pancreatitis. Patients with pancreatic abscesses may have abdominal pain, fever, chills, and nausea/vomiting or an inability to eat. Presentation with alternate symptomatology is extremely unusual. Case Report: A 67-year-old Asian male presented with painless, afebrile obstructive jaundice and a CA 19-9 of 1732 IU. He was found to have a 3.1×2.4 cm low-density lesion in the head of the pancreas and the right lobe of the liver, suggesting malignancy. Surgical management was considered, however additional diagnostic workup, including an endoscopic retrograde cholangiopancreatography (ERCP), was performed to complete staging of the presumed mass. A smooth, 3-cm-long, tapering stricture was found it the common bile duct. It was stented from the common hepatic duct to the duodenum. Subsequent endoscopic ultrasound (EUS) evaluation of the pancreatic head lesion revealed a drainable fluid collection that was aspirated and found to contain pyogenic material on pathology. The patient’s symptoms resolved, and he was subsequently managed conservatively. A repeat ERCP confirmed complete resolution of the previously visualized cystic lesion. Interestingly, laboratory values showed concomitant normalization of CA 19-9 to 40 IU. Conclusions: EUS-guided biopsy is not widely regarded as a required step before surgery, in the management of patients with pancreatic masses. It is generally reserved for determination of resectability or staging, and only utilized when clinically indicated. However, this

    Trueperella pyogenes is a commensal and opportunistic pathogen normally causes mastitis, liver abscesses and pneumonia of economically important livestock. To date, no specific control measure was reported to prevent T. pyogenes infections. In this study, we first constructed a recombinant plasmid pVAX1-PLO based on the main virulent factor pyolysin gene as DNA vaccine against T. pyogenes infection. Subsequently, transient expression of pVAX1-PLO and pcDNA3.1/V5-fIL-1β were identified in Human embryonic kidney cells (HEK293T) by immunofluorescence assay. Humoral and cellular immune responses were evaluated in mice to compare the immunogenicity between different immunized groups. The results showed that the successful expression of PLO or fIL-1β protein was detected by confocal microscopy for cells transfected with plasmid pVAX1-PLO and/or pcDNA3.1/V5-fIL-1β. The mice immunized with pVAX1-PLO elicited a higher titer of PLO-specific antibody than the control group. The levels of IFN-γ and IL-2 were significantly increased in the pVAX1-PLO immunized mice, while the expression level of IL-4 was slightly increased but not significant. These findings suggested that the DNA vaccine pVAX1-PLO can primarily induce Th1 immune response. The residual Colony-Forming Units (CFUs) from the liver and peritoneal fluid were decreased obviously in the pVAX1-PLO treated mice compared with the control. Importantly, co-immunization with pcDNA3.1/V5-fIL-1β and pVAX1-PLO could enhance host humoral and cellular immune responses and significantly protect mouse from T. pyogenes infection. In conclusion, our study provides a promising strategy against T. pyogenes infections and implies the potential clinical application of combined DNA vaccines in diseases control. PMID:27091688

    Over a 5-year period, 56 psoas abscesses occurring in 51 patients were managed by image-guided percutaneous drainage, either by needle aspiration (n = 10) or by catheter drainage (n = 46) in conjunction with medical therapy. Twenty-seven patients had tuberculous abscesses (bilateral in five) while 24 patients had pyogenic abscesses. Percutaneous treatment was successful in 16 of the 24 patients (66.7%) with pyogenic abscesses. The reasons for failure were co-existent bowel lesions, phlegmonous involvement of muscle without liquefaction, multiloculated abscess cavity and thick tenacious pus not amenable to percutaneous drainage. Surgery was required in seven patients, either for failed percutaneous drainage or for the management of co-existent disease. Percutaneous drainage was initially successful in all 27 patients of tuberculous psoas abscesses. However, eight patients presented with recurrence requiring repeat intervention. The average duration of catheter drainage was longer in patients with tuberculous abscess (11 days) than in patients with pyogenic abscess (6 days). Percutaneous drainage under image guidance provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses. PMID:9313737

    Background & objectives: Amoebiasis is a common parasitic infection caused by Entamoeba histolytica and amoebic liver abscess (ALA) is the most common extraintestinal manifestation of amoebiasis. The aim of this study was to standardise real-time PCR assays (Taqman and SYBR Green) to detect E. histolytica from liver abscess pus and stool samples and compare its results with nested-multiplex PCR. Methods: Liver abscess pus specimens were subjected to DNA extraction. The extracted DNA samples were subjected to amplification by nested-multiplex PCR, Taqman (18S rRNA) and SYBR Green real-time PCR (16S-like rRNA assays to detect E. histolytica/E. dispar/E. moshkovskii). The amplification products were further confirmed by DNA sequence analysis. Receiver operator characteristic (ROC) curve analysis was done for nested-multiplex and SYBR Green real-time PCR and the area under the curve was calculated for evaluating the accuracy of the tests to dignose ALA. Results: In all, 17, 19 and 25 liver abscess samples were positive for E. histolytica by nested-multiplex PCR, SYBR Green and Taqman real-time PCR assays, respectively. Significant differences in detection of E. histolytica were noted in the real-time PCR assays evaluated (P<0.0001). The nested-multiplex PCR, SYBR Green real-time PCR and Taqman real-time PCR evaluated showed a positivity rate of 34, 38 and 50 per cent, respectively. Based on ROC curve analysis (considering Taqman real-time PCR as the gold standard), it was observed that SYBR Green real-time PCR was better than conventional nested-multiplex PCR for the diagnosis of ALA. Interpretation & conclusions: Taqman real-time PCR targeting the 18S rRNA had the highest positivity rate evaluated in this study. Both nested multiplex and SYBR Green real-time PCR assays utilized were evaluated to give accurate results. Real-time PCR assays can be used as the gold standard in rapid and reliable diagnosis, and appropriate management of amoebiasis, replacing the

    Amebiasis is an endemic disease and a public health problem throughout Mexico, although the incidence rates of amebic liver abscess (ALA) vary among the geographic regions of the country. Notably, incidence rates are high in the northwestern states (especially Sonora with a rate of 12.57/100,000 inhabitants) compared with the central region (Mexico City with a rate of 0.69/100,000 inhabitants). These data may be related to host genetic factors that are partially responsible for resistance or susceptibility. Therefore, we studied the association of the HLA-DRB1 and HLA-DQB1 alleles with resistance or susceptibility to ALA in two Mexican populations, one each from Mexico City and Sonora. Ninety ALA patients were clinically diagnosed by serology and sonography. Genomic DNA was extracted from peripheral blood mononuclear cells. To establish the genetic identity of both populations, 15 short tandem repeats (STRs) were analyzed with multiplexed PCR, and the allelic frequencies of HLA were studied by PCR-SSO using LUMINEX technology. The allele frequencies obtained were compared to an ethnically matched healthy control group (146 individuals). We observed that both affected populations differed genetically from the control group. We also found interesting trends in the population from Mexico City. HLA-DQB1*02 allele frequencies were higher in ALA patients compared to the control group (0.127 vs 0.047; p= 0.01; pc= NS; OR= 2.9, 95% CI= 1.09-8.3). The less frequent alleles in ALA patients were HLA-DRB1*08 (0.118 vs 0.238 in controls; p= 0.01; pc= NS; OR= 0.42, 95% CI= 0.19-0.87) and HLA-DQB1*04 (0.109 vs 0.214; p= 0.02; pc= NS; OR= 0.40, 95% CI= 0.20-0.94). The haplotype HLA-DRB1*08/-DQB1*04 also demonstrated a protective trend against the development of this disease (0.081 vs. 0.178; p=0.02; pc=NS; OR= 0.40, 95% CI= 0.16-0.93). These trends suggest that the prevalent alleles in the population of Mexico City may be associated with protection against the development of ALA

    Pyogenic psoas abscess in the pediatric age group is a primary condition caused mostly by Staphylococcus aureus. The preferred treatment is percutaneous or surgical drainage under a cover of systemic antibiotics. Laparoscopic drainage scores over open surgery in terms of minimal invasion, shorter hospital stay, better patient comfort, and more complete drainage compared with the percutaneous approach. The authors report a case of a 4-year-old boy with a psoas abscess that was effectively drained laparoscopically through an extraperitoneal approach. PMID:15359416

    The recent WHO report on antibiotic resistances shows a dramatic increase of microbial resistance against antibiotics. With only a few new antibiotics in the pipeline, a different drug delivery approach is urgently needed. We have obtained evidence demonstrating the effectiveness of a cell based drug delivery system that utilizes the innate immune system as targeting carrier for antibacterial drugs. In this study we show the efficient loading of neutrophil granulocytes with chlorhexidine and the complete killing of E. coli as well as Fusobacterium necrophorum in in-vitro studies. Fusobacterium necrophorum causes hepatic abscesses in cattle fed high grain diets. We also show in a mouse model that this delivery system targets infections of F. necrophorum in the liver and reduces the bacterial burden by an order of magnitude from approximately 2•106 to 1•105.

    In a previous study, we demonstrated that oral immunization using Autographa californica baculovirus driving the expression of the Gal-lectin LC3 fragment (AcNPV-LC3) of Entamoeba histolytica conferred protection against ALA development in hamsters. In this study, we determined the ability of AcNPV-LC3 to protect against ALA by the intramuscular route as well as the liver immune response associated with protection. Results showed that 55% of hamsters IM immunized with AcNPV-LC3 showed sterile protection against ALA, whereas other 20% showed reduction in the size and extent of abscesses, resulting in some protection in 75% of animals compared to the sham control group. Levels of protection showed a linear correlation with the development and intensity of specific antiamoeba cellular and humoral responses, evaluated in serum and spleen of hamsters, respectively. Evaluation of the Th1/Th2 cytokine patterns expressed in the liver of hamsters showed that sterile protection was associated with the production of high levels of IFNγ and IL-4. These results suggest that the baculovirus system is equally efficient by the intramuscular as well as the oral routes for ALA protection and that the Gal-lectin LC3 fragment is a highly protective antigen against hepatic amoebiasis through the local induction of IFNγ and IL-4.

    Three cases of pituitary abscess are presented. The history of recurrent attacks of aseptic meningitis, together with radiological and clinical features suggestive of pituitary tumor, appear to form a fairly typical picture of the condition. Long follow-up was possible in two of the cases. There are no radiological features which distinguish the lesion from pituitary tumor, hence the importance of recognizing the significance of such a clinical presentation with radiological evidence of sellar enlargement. Pituitary abscesses seem to occur in preexisting pituitary tumors. The possible relationship with pituitary infarction is discussed. PMID:865667

    We here compared pathogenic (p) and non-pathogenic (np) isolates of Entamoeba histolytica to identify molecules involved in the ability of this parasite to induce amoebic liver abscess (ALA)-like lesions in two rodent models for the disease. We performed a comprehensive analysis of 12 clones (A1–A12) derived from a non-pathogenic isolate HM-1:IMSS-A and 12 clones (B1–B12) derived from a pathogenic isolate HM-1:IMSS-B. “Non-pathogenicity” included the induction of small and quickly resolved lesions while “pathogenicity” comprised larger abscess development that overstayed day 7 post infection. All A-clones were designated as non-pathogenic, whereas 4 out of 12 B-clones lost their ability to induce ALAs in gerbils. No correlation between ALA formation and cysteine peptidase (CP) activity, haemolytic activity, erythrophagocytosis, motility or cytopathic activity was found. To identify the molecular framework underlying different pathogenic phenotypes, three clones were selected for in-depth transcriptome analyses. Comparison of a non-pathogenic clone A1np with pathogenic clone B2p revealed 76 differentially expressed genes, whereas comparison of a non-pathogenic clone B8np with B2p revealed only 19 differentially expressed genes. Only six genes were found to be similarly regulated in the two non-pathogenic clones A1np and B8np in comparison with the pathogenic clone B2p. Based on these analyses, we chose 20 candidate genes and evaluated their roles in ALA formation using the respective gene-overexpressing transfectants. We conclude that different mechanisms lead to loss of pathogenicity. In total, we identified eight proteins, comprising a metallopeptidase, C2 domain proteins, alcohol dehydrogenases and hypothetical proteins, that affect the pathogenicity of E. histolytica.

Comparison of a non-pathogenic clone A1np with pathogenic clone B2p revealed 76 differentially expressed genes, whereas comparison of a non-pathogenic clone B8np with B2p revealed only 19 differentially expressed genes. Only six genes were found to be similarly regulated in the two non-pathogenic clones A1np and B8np in comparison with the pathogenic clone B2p. Based on these analyses, we chose 20 candidate genes and evaluated their roles in ALA formation using the respective gene-overexpressing transfectants. We conclude that different mechanisms lead to loss of pathogenicity. In total, we identified eight proteins, comprising a metallopeptidase, C2 domain proteins, alcohol dehydrogenases and hypothetical proteins, that affect the pathogenicity of E. histolytica.

    A 2 x 2 factorial experiment with 48 crossbred steers (with Hereford, Angus, and Charolais genetics, and an initial BW of 373 +/- 8.4 kg) was conducted to evaluate the effects of dietary sunflower seeds (SS) and tylosin phosphate (TP) on production factors, carcass characteristics, liver abscess incidence, and fatty acid composition of the muscle (pars costalis diaphragmatis; PCD) and subcutaneous fat. Individually penned steers were fed either a control diet of 84.5% rolled barley, 14% barley silage, and 1.5% mineral and vitamin mix on a DM basis, or an SS diet, in which SS replaced 15% of the diet. Half the animals fed each diet received TP at 11 mg/kg of DM as a top dressing. Interactions were significant for all production factors. A reduction (P = 0.008) in DMI was observed from 10.1 +/- 0.4 kg/d, in steers fed the control diet, to 8.9 +/- 0.3 and 8.6 +/- 0.3 kg/d, in steers fed the SS and SS + TP diets, respectively. Greater (P = 0.014) ADG was observed for steers fed the control diet than for those fed the SS or SS + TP diet (1.4 vs. 1.1 and 1.2, SE = 0.1 kg/d, respectively); however, G:F ratios were greater (P = 0.011) in steers fed the control diets than in those fed the SS diets. Steers fed the control and SS diets had the heaviest and lightest HCW (347 +/- 6.9 vs. 325 +/- 8.4 kg; P = 0.025), respectively. Lean meat yield (%) of steers fed SS was greater (P = 0.117) than in steers fed the control diets, whereas total lean yield [(HCW x lean meat yield)/100] was similar (P = 0.755). Provision of the SS or SS + TP diet eliminated (P = 0.08 for interaction) liver abscesses compared with the 36 and 9% incidence in steers fed the control or control + TP diet, respectively. Fatty acid weight percentages (wt%) followed similar patterns in PCD and subcutaneous fat. Feeding the SS diets led to greater (P = 0.001) wt% of 18:0 and 18:2n-6, but reduced the wt% of 16:0, 9-cis (c)-18:1, and 18:3n-3 in PCD compared with that in steers fed the control diets, but the wt

  6. Two cases of monomicrobial intraabdominal abscesses due to KPC - 3 Klebsiella pneumoniae ST258 clone

    2011-01-01

    Background Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of Klebsiella pneumoniae carbapenemase-producing bacteria is an emerging cause of abdominal infections. Case presentation We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by Klebsiella pneumoniae Sequence Type 258 producing K. pneumoniae carbapenemase 3 (KPC-Kp). In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection of a pancreatic pseudocystic lesion caused by KPC-Kp. In case 2, a 64-year-old HIV- negative Italian woman with pancreatic neoplasm and liver metastases developed a liver abscess due to KPC after surgery. Both women were admitted to our hospital but to different surgical units. The clonal relationship between the two isolates was investigated by pulsed-field gel electrophoresis (PFGE). In case 2, the patient was already colonized at admission and inter-hospital transmission of the pathogen was presumed. A long-term combination regimen of colistin with tigecycline and percutaneous drainage resulted in full recovery and clearance of the multidrug-resistant (MDR) pathogen. Conclusions Timely microbiological diagnosis, the combined use of new and old antibiotics and radiological intervention appeared to be valuable in managing these serious conditions. The emergence and dissemination of MDR organisms is posing an increasing challenge for physicians to develop new therapeutic strategies and control and prevention frameworks. PMID:21961811

    Mucosal vaccination against amoebiasis using the Gal-lectin of E. histolytica has been proposed as one of the leading strategies for controlling this human disease. However, most mucosal adjuvants used are toxic and the identification of safe delivery systems is necessary. Here, we evaluate the potential of a recombinant Autographa californica baculovirus driving the expression of the LC3 fragment of the Gal-lectin to confer protection against amoebic liver abscess (ALA) in hamsters following oral or nasal immunization. Hamsters immunized by oral route showed complete absence (57.9%) or partial development (21%) of ALA, resulting in some protection in 78.9% of animals when compared with the wild type baculovirus and sham control groups. In contrast, nasal immunization conferred only 21% of protection efficacy. Levels of ALA protection showed lineal correlation with the development of an anti-amoebic cellular immune response evaluated in spleens, but not with the induction of seric IgG anti-amoeba antibodies. These results suggest that baculovirus driving the expression of E. histolytica vaccine candidate antigens is useful for inducing protective cellular and humoral immune responses following oral immunization, and therefore it could be used as a system for mucosal delivery of an anti-amoebic vaccine.

    The role of calreticulin (CRT) in host-parasite interactions has recently become an important area of research. Information about the functions of calreticulin and its relevance to the physiology of Entamoeba parasites is limited. The present work demonstrates that CRT of both pathogenic E. histolytica and nonpathogenic E. dispar species specifically interacted with human C1q inhibiting the activation of the classical complement pathway. Using recombinant EhCRT protein, we demonstrate that CRT interaction site and human C1q is located at the N-terminal region of EhCRT. The immunofluorescence and confocal microscopy experiments show that CRT and human C1q colocalize in the cytoplasmic vesicles and near to the surface membrane of previously permeabilized trophozoites or are incubated with normal human serum which is known to destroy trophozoites. In the presence of peripheral mononuclear blood cells, the distribution of EhCRT and C1q is clearly over the surface membrane of trophozoites. Nevertheless, the level of expression of CRT in situ in lesions of amoebic liver abscess (ALA) in the hamster model is different in both Entamoeba species; this molecule is expressed in higher levels in E. histolytica than in E. dispar. This result suggests that EhCRT may modulate some functions during the early moments of the host-parasite relationship. PMID:24860808

    Filter paper was used as a support to absorb micro samples of finger prick blood for detection of antibodies to Entamoeba histolytica (causative organism of amebiasis) by a rapid dipstick dot-EIA technique; 8 microliters of blood was sufficient to saturate discs (diameter 6 mm) of Whatman paper No. 3. Conditions of elution of blood from the discs were optimized and the best results were obtained when 0.4 ml of buffer was used for elution for 30 minutes at room temperature. The filter paper technique is extremely useful for field use and for diagnosis of amebic liver abscess on a large scale since it does not involve centrifugation of blood and use of sterile vials because blood dried on paper can be stored in polythene bags at room temperature for up to 3 months and for a week at 42 degrees C without significant loss of antibody activity, thereby eliminating the need of refrigeration of samples for storage or transportation to a reference laboratory. Elution of blood from different discs of the same patient was found to be highly reproducible without appreciable loss of sensitivity or specificity. Twenty-four confirmed ALA, 29 non-ALA, and 25 apparently normal healthy controls, with no previous history of amebiasis, were tested. Sensitivity and specificity of the test was found to be 96% and 92%, respectively. PMID:8189328

    Infectious diseases are the leading cause of FUO. A case of prolonged fever with hepatic and pulmonary tuberculosis as a final diagnosis is herein presented. A 4-year-old, otherwise healthy boy presented with an axillary temperature of up to 39.5ºC for the previous 3 weeks. His medical history revealed an occasional increase in body temperature up to 38.5ºC for the last 6 months. Physical examination revealed coarse breath sounds on the basal lung area. Chest X-ray showed mediastinal lymphadenomegaly and computed tomography revealed paratracheal conglomerated lymph nodes and a groundglass appearance on the right lung. There were multiple contrast-enhanced, hypoechoic nodules with central necrosis in the liver parenchyma on abdominal magnetic resonance imaging. Open liver biopsy yielded chronic granulomatous inflammation compatible with pathological findings of tuberculosis infection. The culture specimen was positive for Mycobacterium tuberculosis. The patient improved rapidly after antituberculous therapy was initiated. Tuberculosis, especially in its disseminated form, poses a distinct diagnostic challenge in cases of prolonged fever with unproven etiology, and thus persistence should be exercised in disclosing the cause of such fevers.

    Entamoeba histolytica in culture produces a pentapeptide (MQCNS). This oligopeptide inhibits the in vitro and in vivo locomotion of human monocytes, hence its denomination Monocyte Locomotion Inhibitory Factor (MLIF). The original isolated peptide and its synthetic construct display similar effects, among others, being inhibition of the respiratory burst in monocytes and neutrophils, decrease of Dinitrochlorobenzene (DNCB) skin hypersensitivity in guinea pigs and gerbils, and delay of mononuclear leukocytes in human Rebuck skin windows with inhibition of vascular cell Very late antigen (VLA)-4 and Vascular adhesion molecules (VCAM) in endothelia and monocytes. The MLIF molecular mechanism of action is unknown, but data reveal its implication in Nuclear factor-kappa B (NF-κB) and Mitogenactivated protein kinase (MAPK) pathways. This could explain MLIF multiplicity of biological effects. On the other hand, the amebic peptide has been useful in treating experimental amebiasis of the liver. The amebic peptide is effective in reducing inflammation induced by carragenin and arthritis in a Collagen-induced arthritis (CIA) model. Microarray data from experimental arthritis revealed an MLIF gene expression profile that includes genes that are involved in apoptosis, cell adhesion, extracellular matrix, and inflammation / chemotaxis. MLIF could be involved in unsuspected biological factions because there is increasing data on the peptide effect on several cell activities. This review also presents uses of MLIF as described in patents. PMID:22074573

    Propionibacterium acnes is a rare, but established, cause of intracranial abscesses. We describe a case of P. acnes brain abscess in an immunocompetent man without prior neurosurgery. A 49-year old man with mild psoriasis presented with a two-week history of gait changes, generalized weakness and a two-day history of headaches, aphasia and confusion. Imaging revealed a left thalamic mass and surgical biopsy suggested a pyogenic abscess. Cultures of biopsy samples of the abscess grew P. acnes alone. MRI and serial neurological exam showed marked clinical improvement with intravenous antibiotics. The significant reduction in the abscess was sustained on MRI obtained at six weeks after completion of antibiotic therapy. In conclusion, P. acnes must be considered as a differential diagnosis in individuals presenting with features suggestive of a brain abscess even in the absence of immunosuppression or previous neurosurgery.

    Obturator internus muscle (OIM) abscess is an uncommon entity often mistaken for septic arthritis of the hip. We describe seven children with OIM abscess and review seven previously reported cases. The most common presenting symptoms were hip or thigh pain (14 patients), fever (13), and limp (13). The hip was flexed, abducted, and externally rotated in 11 patients. Magnetic resonance imaging and computed tomography (CT) were diagnostic for OIM abscess in the 14 patients. Associated abscesses were located in the obturator externus muscle (5 patients), psoas muscle (2), and iliac muscle (1). The etiologic agents were Staphylococcus aureus (8 patients), Streptococcus pyogenes (2), Neisseria gonorrhoeae (2), and Enterococcus faecalis (1). Three patients underwent CT-guided percutaneous drainage, and three had surgical drainage. Three patients had ischial osteomyelitis in addition to OIM abscess. The 11 children with uncomplicated OIM abscess were treated for a median of 28 days. All patients had an uneventful recovery. PMID:10028081

    Primary hepatothiasis (HL) and recurrent pyogenic cholangitis (RPC) are two terms describing the different aspects of the same disease, with HL emphasizing the pathologic changes and RPC emphasizing the clinical presentation and suppurative inflammation. It is predominantly a disease of the Far East. In the 1960s, it was the third most common cause of emergency abdominal surgery at a university hospital in Hong Kong. Thereafter, its incidence has decreased considerably, possibly due to improved standards of living and Westernized diet. Clinically, patients may present acutely with recurrent bacterial cholangitis and its possible complications, such as liver abscess and septicemic shock, or with chronic complications, such as cholangiocarcinoma. Pathologically, it is characterized by pigmented calcium bilirubinate stones within dilated intrahepatic bile ducts featuring chronic inflammation, mural fibrosis, and proliferation of peribiliary glands, without extrahepatic biliary obstruction. Episodes of suppurative inflammation cumulate in sclerosing cholangitis of peripheral ducts and parenchymal fibrosis resulting from collapse and scarring. Mass-forming inflammatory pseudotumor and neoplasms like intraductal papillary neoplasms and cholangiocarcinoma are increasingly recognized complications. Modern imaging techniques allow definitive diagnosis, accurate assessment for treatment planning, and detection of complications. A multidisciplinary team approach (interventional endoscopist, interventional radiologist, hepatobiliary surgeon, and intensivists) is important for optimal patient outcome. PMID:21344349

This case report describes the clinical and echocardiographic findings in an 8 year old Brown Swiss cow presented with an intramural myocardial abscess. The main clinical findings were anorexia, drop in milk yield, fever, tachycardia, and hyperfibrinogenemia. Neither heart murmurs nor cardiac arrhythmias were present on auscultation. Transthoracic echocardiographic examination revealed a prominent intramural mass embedded in the left ventricular free wall and bulging into the lumen of the left ventricle. Diagnosis was confirmed at necropsy. A culture of the abscess grew Trueperella pyogenes. PMID:26900053

    Pyogenic sacroiliitis is an extremely rare disease in the field of obstetrics and gynecology, and especially for the cases discovered and treated during pregnancy, only five cases can be found in literature. We experienced one case of the disease in which the patient needed urgent hospitalization due to dysbasia caused by fever and pain at the left hip at the 27th week of her pregnancy. The patient was a 31-year-old primipara presenting typical clinical symptoms of pyogenic sacroiliitis along with evidence of severe infection as represented by fever of 39.7 degrees C and CRP of 12.6 mg/dl. She showed a good response to meropenem (MEPM) at 1 g twice a day for 8 days and then at 0.5 g twice a day for 2 days, followed by faropenem (FRPM) at 200 mg three times a day for 12 days, which successfully improved her subjective and objective findings as well as her laboratory test values, resulting in a complete cure. The definitive diagnosis of the disease in the patient was made on the basis of MRI findings, but no pathogen was identified. The patient was found to have marginal placenta previa as a complication, but she had an uneventful trans-vaginal delivery at the 37th week of her pregnancy and left hospital after both she and her baby showed favorable post-delivery progress. The case reported here is the first case of pyogenic sacroiliitis that has ever been discovered and treated during pregnancy in Japan. PMID:11729713

    Study Design. A case report and review of the literature. Objective. The aim of this study was to describe the conservative management of pyogenic spondylitis around the odontoid process. Summary of Background Data. Atlantoaxial subluxation after pyogenic spondylitis is rare. The therapeutic approach to infection of the upper cervical spine is controversial. Methods. Medical chart and radiological images of a 76-year-old male patient were retrospectively reviewed. Radiography revealed atlantoaxial subluxation, and an abscess was seen around the odontoid process on magnetic resonance images. Intravenous antibiotics and a halo vest were used to treat the patient. We then observed the patient's conservative treatment course. Results. C-reactive protein levels returned to normal 4 weeks after administration of the intravenous antibiotics. The patient's muscle weakness also completely recovered 8 weeks after administration of the intravenous antibiotics. Because the patient was able to walk without any support, surgical treatment was not necessary. Conclusions. Pyogenic spondylitis of the upper cervical spine is a rare manifestation. Surgical or conservative treatment must be selected carefully based on the patient's symptoms. If early diagnosis and treatment can be provided to the patients, conservative treatment can be achieved. PMID:26090255

    We report a case of cervical pyogenic spondylitis complicated by epidural abscess with quadriplegia during treatment of severe burns. The patient was a 49-year-old man with 3rd-degree burns to 20% of his body, involving the lower extremities. We performed escharectomy of the 3rd-degree necrosis on days 7 and 16, followed by the first skin graft on day 23. Pseudomonas aeruginosa was detected in the postoperative graft wound culture. On day 23 after the skin graft, he became febrile and began to experience cervical pain and muscle weakness of the extremities. By day 24, quadriplegia had developed. A cervical vertebral magnetic resonance imaging (MRI) scan showed pyogenic spondylitis with an epidural abscess, which was causing the quadriplegia. We treated the patient by performing curettage of the pyogenic lesion and anterior fixation of the cervical vertebral bodies. The fact that P. aeruginosa was detected in the pyogenic focus culture indicated that burn wound sepsis was responsible for the infection. This case reinforces that acting on a strong suspicion helps to establish a diagnosis and initiate appropriate treatment early. PMID:17072727

    Pyogenic granuloma (PG) is a kind of inflammatory hyperplasia seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection. In reality it arises in response to various stimuli such as low-grade local irritation, traumatic injury or hormonal factors. It predominantly occurs in the second decade of life in young females possibly because of the vascular effects of female hormones. It is also called as pregnancy tumor because of its high frequency of occurrence during the early part of pregnancy. Even though, this lesion is non-neoplastic and treatment procedure is simple, it should be diagnosed correctly before proceeding with the treatment. The most common site for PGs is gingiva (75%) and rarely in the palate. In this case report, we are going to present very rare occurrence of pregnancy tumor in the hard palate. PMID:23956603

Statistical tests showed no significant difference between the colony counts of S. pyogenes by itself and growth when mixed with Lactobacilli, and no significant difference between the colony counts of S. pyogenes in the four different concentrations of Lactobacilli. Conclusion. The statistical data representing the growth of these two organisms suggests that Lactobacilli did not inhibit the growth of S. pyogenes. Also, S. pyogenes did not inhibit the growth of Lactobacilli. PMID:20508738

    A study of cases of retropharyngeal abscess in Nigerian children was carried out. It occurred most commonly in children under the age of 6 months and in more male children than female in a ratio of 5:3. Most children seen at the Lagos University Teaching Hospital were brought in late with the upper airway already obstructed. A diagnostic tool of soft-tissue x-ray examination of the neck is not foolproof. In fact, 22.58 percent of soft-tissue x-ray examinations of the neck in this study produced false-positive results. Factors contributing to these results are discussed. Bacteriology showed the main organisms to be Hemophilus influenzae (45.84 percent) and Streptococcus pyogenes (33.33 percent). All cases were found to be secondary to upper respiratory tract infection. PMID:3950981

    Significant advances in the diagnosis and management of bacterial brain abscess over the past several decades have improved the expected outcome of a disease once regarded as invariably fatal. Despite this, intraparenchymal abscess continues to present a serious and potentially life-threatening condition. Brain abscess may result from traumatic brain injury, prior neurosurgical procedure, contiguous spread from a local source, or hematogenous spread of a systemic infection. In a significant proportion of cases, an etiology cannot be identified. Clinical presentation is highly variable and routine laboratory testing lacks sensitivity. As such, a high degree of clinical suspicion is necessary for prompt diagnosis and intervention. Computed tomography and magnetic resonance imaging offer a timely and sensitive method of assessing for abscess. Appearance of abscess on routine imaging lacks specificity and will not spare biopsy in cases where the clinical context does not unequivocally indicate infectious etiology. Current work with advanced imaging modalities may yield more accurate methods of differentiation of mass lesions in the brain. Management of abscess demands a multimodal approach. Surgical intervention and medical therapy are necessary in most cases. Prognosis of brain abscess has improved significantly in the recent decades although close follow-up is required, given the potential for long-term sequelae and a risk of recurrence. PMID:25360205

    Hepatic abscess due to perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon. Pre-operative diagnosis is difficult as patients are often unaware of the foreign body ingestion and symptoms and imagiology are usually non-specific. The authors report a case of 62-year-old woman who was admitted with fever and abdominal pain. Further investigation revealed hepatic abscess, without resolution despite antibiotic therapy. A liver abscess resulting from perforation and intra-hepatic migration of a bone coming from the pilorum was diagnosed by surgery. The literature concerning foreign body-induced perforation of the gastrointestinal tract complicated by liver abscess is reviewed. PMID:17457985

    Pyogenic sacroiliitis is a rare osteoarticular infection, occurring most frequently in children and young adults. Diagnosis of the disease is challenging because of a general lack of awareness of the disease and its nonspecific signs and symptoms. Staphylococcus aureus is the most common causative bacteria in pyogenic sacroiliitis. Methicillin-resistant S. aureus (MRSA) has typically been considered a hospital-associated pathogen; however, community-acquired (CA)-MRSA infections are becoming increasingly common in Korea. We report the first domestic case of acute pyogenic sacroiliitis with abscess and bacteremia caused by CA-MRSA. The pathogen carried the type IV-A staphylococcal cassette chromosome mec (SCCmec) without the Panton-Valentine leukocidin (PVL) gene, and was identified as sequence type (ST) 72 by multilocus sequence typing.

    To characterize patients with parapharyngeal abscess admitted to a Danish tertiary care centre and evaluate our management. This is a retrospective chart review. All records of patients with parapharyngeal abscess admitted to the Ear-Nose-Throat Department at Aarhus University Hospital, Denmark, from January 2001 through December 2011 were reviewed. In total, 63 patients (41 males), aged 4-89 years (median, 45 years) were included in the study. The mean annual incidence of parapharyngeal abscess was 0.9 cases/100,000 population. Thirty-three (52%) patients had concomitant peritonsillar abscess. In two patients the parapharyngeal abscess was accompanied by necrotizing fasciitis. The most frequent surgical approach used was intrapharyngeal incision in combination with tonsillectomy. The most commonly used antibiotic regimen was benzylpenicillin plus metronidazole. Seven (13%) patients returned to the operating theatre due to post-tonsillectomy haemorrhage or insufficient abscess drainage. Tonsillectomy and internal incision of the abscess in combination with a narrow-spectrum intravenous penicillin and metronidazole is a safe and efficient approach for managing parapharyngeal abscesses. This approach, however, carries a relatively high complication rate, requiring close surveillance in the early post-operative period. This is especially true for parapharyngeal abscess patients without peritonsillar abscess. In our series, these patients were more ill, more likely to experience complications, require intensive care, intubation, and tracheotomy, than parapharyngeal abscess patients with concurrent peritonsillar abscess. The frequent co-existence of parapharyngeal abscess and peritonsillar abscess favours careful consideration of addition of tonsillectomy to intrapharyngeal incision. PMID:23982668

    Iliopsoas abscess (IPA) is rare in children, particularly in neonates. A male neonate was born at 38 weeks of gestation with a weight of 2915 g. On day 22 after birth, his family noticed that his right thigh was swollen. Abdominal computed tomography showed a mass extending to the right iliopsoas from the right thigh with thick septa. Puncture to the right groin yielded purulent fluid, and so a diagnosis of abscess was made. The puncture was followed by surgical drainage through a small inguinal incision, and the abscess cavity was irrigated thoroughly using normal saline. Culture of abscess fluid was positive for Streptococcus pneumoniae, so intravenous ABPC infusion was continued. The postoperative magnetic resonance imaging indicate that the IPA was derived from arthritis of the hip, and the patients received Riemenbügel for the incomplete hip dislocation. He is doing well at 2 years of age. PMID:23005905

    INTRODUCTION Thyroid abscesses are uncommon because the gland is relatively resistant to developing infection due to its rich blood supply, well-developed capsule and high iodine content. However, clinicians must be aware of this differential to make an early diagnosis. PRESENTATION OF CASE We present the case of a patient who required urgent operative resection as definitive treatment for a thyroid abscess secondary to infection with Staphylococcus aureus. DISCUSSION Although this is rare, a thyroid abscess left untreated can lead to serious morbidity. Therefore, clinicians must be aware of the presenting features and therapeutic options. CONCLUSION Thyroid abscess is an uncommon diagnosis but can lead to significant morbidity. Therefore clinicians must be aware of the diagnosis in order to institute early aggressive management.

    Brain abscess is a life threatening illness, demanding rapid diagnosis and treatment. Its development requires seeding of an organism into the brain parenchyma, often in an area of damaged brain tissue or in a region with poor microcirculation. The lesion evolves from a cerebritis stage to capsule formation. Brain abscesses can be caused by contiguous or haematogenous spread of an infection, or by head trauma/ neurosurgical procedure. The most common presentation is that of headache and vomiting due to raised intracranial pressure. Seizures have been reported in up to 50% of cases. Focal neurological deficits may be present, depending on the location of the lesion. Treatment of a brain abscess involves aspiration or excision, along with parenteral antibiotic therapy. The outcome has improved dramatically in the last decades due to improvement in diagnostic techniques, neurosurgery, and broad-spectrum antibiotics. The authors provide an overview of the pathogenesis, diagnosis and management of brain abscesses. PMID:23341403

    A spinal epidural abscess developed in a renal transplant recipient; results of a serum radioimmunoassay for Aspergillus antigen were positive. Laminectomy disclosed an abscess of the L4-5 interspace and L-5 vertebral body that contained hyphal forms and from which Aspergillus species was cultured. Serum Aspergillus antigen radioimmunoassay may be a valuable, specific early diagnostic test when systemic aspergillosis is a consideration in an immunosuppressed host.

    Splenic abscess is a rare clinical entity but may be underreported. A retrospective study at Srinagarind Hospital revealed 60 cases of splenic abscess between 1992 and 2001. The causative organisms were identified in 41 cases (68.3%). Gram negative bacilli were commonly isolated and Burkholderia pseudomallei was the most predominant. Diabetes mellitus and leukemia were common underlying diseases found in 46.3 per cent and 9.7 per cent of culture confirmed cases, respectively. The patients usually presented with fever, left upper quadrant pain, tenderness and splenomegaly. Multiple abscesses were more commonly found in the melioidosis than in the non-melioidosis group (p = 0.032), but a single abscess was more commonly found in the non-melioidosis than in the melioidosis group (p = 0.032). Concurrent liver abscesses, often multiple, were not different in both groups. Antimicrobials alone were given in 66.7 per cent of cases with melioidosis and 64.7 per cent of non-melioidosis group. Splenectomy and percutaneous aspiration were performed only in 29.3 per cent and 4.9 per cent of cases with splenic abscess. The overall mortality rate of splenic abscess was only 4.9 per cent in the present series. In conclusion, splenic abscess is not uncommon. Burkholderia pseudomalleli is the most common causative agent found in the present series. Therefore, it should be targeted in the initial empirical antibiotic therapy before the culture results are available especially when multiple lesions in the spleen and concurrent multiple liver abscesses are seen. Prolonged treatment with appropriate antimicrobials alone is usually effective. Splenectomy and/or aspiration may be useful in selected patients. PMID:12859100

    Aim: We evaluated the potential of magnetic resonance imaging (MRI) in the diagnosis of spinal infections and specifically its accuracy in differentiating tubercular and pyogenic spondylodiscitis. Materials and Methods: Totally, 50 patients referred for MRI scans with the clinical diagnosis of spinal infections were included in our study. The patients were classified as tubercular (TS), pyogenic (PS), and indeterminate spondylodiscitis on the basis of imaging findings and were correlated with the final diagnosis made by histopathology/cytology/culture/biochemistry or with successful therapeutic outcome. Imaging findings were subsequently analyzed for differentiating tubercular and pyogenic spondylodiscitis using the Chi-square test. Results: The most common pattern of spinal infection was spondylodiscitis (78% incidence rate) with epidural extension (86%) and cord compression (64%) being most common complications observed. Imaging (postcontrast study) and final diagnosis correlated in 93.7% tubercular (sensitivity of 75% and specificity of 90%) and 75% pyogenic (sensitivity of 90% and specificity of 83.3%) spondylodiscitis. The patients with tubercular spondylitis had a significantly (P < 0.05) higher incidence of following MRI findings: A well-defined paraspinal abnormal signal (80% in TS vs. 40% in PS), a thin and smooth abscess wall (84.2% in TS vs. 10% in PS), presence of intraosseous abscess (35% in TS vs. 0% in PS), focal and heterogenous enhancement of the vertebral body (75% in TS vs. 20% in PS), vertebral destruction more than or equal to grade 3 (71.8% in TS vs. 0% in PS), loss of cortical definition (75% in TS vs. 20% in PS), and spinal deformity (50% in TS vs. 5% in PS). Conclusion: Contrast-enhanced images improve the sensitivity and specificity of detection and differentiation of tubercular and PS. PMID:26283836

    Pyogenic granuloma is thought to represent an exuberant tissue reaction to local irritation. It occurs in second decade of life in young females. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic growth, pedunculated or sessile, which usually bleeds on provocation. Oral pyogenic granuloma preferentially affects the gingiva. On rare occasion, it can be found extragingivally on lips, tongue, buccal mucosa, and palate which may mimic more serious pathological conditions such as malignancies. This article reports an unusual case of extra gingival pyogenic granuloma occurring on the right buccal mucosa in a female patient and discusses the features that distinguish this lesion from other similar oral mucosal lesions.

    Background and Objectives: Brain abscess remains a potentially fatal central nervous system (CNS) disease, especially in developing countries. Anaerobic abscess is difficult to diagnose because of cumbersome procedures associated with the isolation of anaerobes. Materials and Methods: This is a hospital-based retrospective microbiological analysis of 430 brain abscess materials (purulent aspirates and/or tissue), for anaerobic organisms, that were received between 1987–2014, by the Microbiology Laboratory in our Institute. Results: Culture showed growth of bacteria 116/430 (27%) of the cases of which anaerobes were isolated in 48/116 (41.1%) of the cases. Peptostreptococcus (51.4 %), was the predominant organism isolated in four cases followed by Bacteroides and Peptococcus species. Conclusion: Early diagnosis and detection of these organisms would help in the appropriate management of these patients. PMID:27307977

    Background Understanding the distribution of disease in wildlife is key to predicting the impact of emerging zoonotic one health concerns, especially for wildlife species with extensive human and livestock interfaces. The widespread distribution and complex interactions of white-tailed deer (Odocoileus virginianus) with humans suggest deer population health and management may have implications beyond stewardship of the animals. The intracranial abscessation suppurative meningitis (IASM) disease complex in deer has been linked to Arcanobacterium pyogenes, an under-diagnosed and often misdiagnosed organism considered commensal in domestic livestock but associated with serious disease in numerous species, including humans. Methods Our study used standard bacterial culture techniques to assess A. pyogenes prevalence among male deer sampled across six physiogeographic regions in Maryland and male and female deer in the Upper Eastern Shore under Traditional Deer Management (TDM) and Quality Deer Management (QDM), a management protocol that alters population demographics in favor of older male deer. Samples were collected from antler pedicles for males, the top of the head where pedicles would be if present for females, or the whole dorsal frontal area of the head for neonates. We collected nasal samples from all animals by swabbing the nasopharyngeal membranes. A gram stain and catalase test were conducted, and aerobic bacteria were identified to genus and species when possible. We evaluated the effect of region on whether deer carried A. pyogenes using Pearson's chi-square test with Yates’ continuity correction. For the white-tailed deer management study, we tested whether site, age class and sex predisposed animals to carrying A. pyogenes using binary logistic regression. Results A. pyogenes was detected on deer in three of the six regions studied, and was common in only one region, the Upper Eastern Shore. In the Upper Eastern Shore, 45% and 66% of antler and nasal

    Intracranial abscess disease is a cause of natural mortality for mature male white-tailed deer (Odocoileus virginianus). Most cases of abscesses are associated with bacterial infection byTrueperella (Arcanobacterium) pyogenes, but a complete understanding of the epidemiology of this disease is lacking. We quantified the effects of individual characteristics, site-specific herd demographics, land cover, and soil variables in estimating the probability of this disease. We examined 7,545 white-tailed deer from 60 sites throughout Georgia US for signs of cranial abscesses, the predecessor of intracranial abscesses, and recorded the presence or absence of cranial abscesses for each individual examined. We detected no cranial abscesses in 2,562 female deer but 91 abscesses in 4,983 male deer examined (1.8%). A generalized linear mixed model, treating site as a random effect, was used to examine several potential explanatory risk factors including site-level landscape and soil characteristics (soil and forest type), demographic factors (deer density and male to female ratio), and individual host factors (deer sex and age). Model results indicated that the probability of a male having a cranial abscess increased with age and that adult sex ratio (male:female) was positively associated with this disease. Site-specific variables for land cover and soil types were not strongly associated with observations of the disease at the scale measured and a large amount of among-site variability remained. Given the demonstrated effect of age, gender, and local sex ratios but the remaining unexplained spatial variability, additional investigation into spatiotemporal variation of the presumed bacterial causative agent of cranial abscesses appears warranted.

The patient had a drainage of the abscess through a flank incision followed by percutaneous nephrostomy and open ureterolithotomy. Metabolic acidosis, hyperuricemia, hypocitraturia, and hypercalciuria appear to be significant in the pathogenesis of urolithiasis in patients with GSD-1. Regular ultrasonography of the abdomen along with optimal metabolic control may delay or prevent urolithiasis and its complications in GSD-1 patients. PMID:16932895

He was found, on abdominal ultrasound, to have a right lobe hepatic cystic lesion. MRI of the abdomen confirmed a hepatic abscess. Cultures obtained under CT guidance showed the abscess to be caused by Fusobacterium necrophorum. This is a rare bacterium that can cause potentially fatal liver abscesses. Following drainage and intravenous antibiotic treatment, the patient improved and was discharged on a 4-week antibiotic course. An abdominal CT, performed 6 weeks after discharge, showed total resolution of the abscess. The patient had, 2 weeks prior to the development of the liver abscess, undergone routine dental cleaning. Neither upper respiratory symptoms nor sore throat had been identified prior to the presentation. PMID:26933183

    Hepatic artery pseudoaneurysms (HAP) are uncommon, occurring mostly as a complication of trauma (accidental or iatrogenic). Liver abscess rarely causes HAP and multiple HAP associated with cholangitic abscesses have not been reported in the literature. We present a patient of acute necrotizing pancreatitis with stent block cholangitis and multiple cholangitic abscesses who developed hemorrhagic output through drainage catheter in the liver abscess. A multiphasic CT angiography demonstrated three HAP, which were treated with a combination of endovascular coil embolization and percutaneous thrombin injection. The fact that cholangitic abscesses may be associated with pseudoaneurysms should not be neglected, considering the potentially catastrophic complication and relatively easy radiological management. CT angiography permits accurate diagnosis and lays down the roadmap for endovascular procedures. PMID:27081232

    Brain abscess (BA) is defined as a focal infection within the brain parenchyma, which starts as a localized area of cerebritis, which is subsequently converted into a collection of pus within a well-vascularized capsule. BA must be differentiated from parameningeal infections, including epidural abscess and subdural empyema. The BA is a challenge for the neurosurgeon because it is needed good clinical, pharmacological, and surgical skills for providing good clinical outcomes and prognosis to BA patients. Considered an infrequent brain infection, BA could be a devastator entity that easily left the patient into dead. The aim of this work is to review the current concepts regarding epidemiology, pathophysiology, etiology, clinical presentation, diagnosis, and management of BA. PMID:24174804

    AIM: To evaluate the computed tomography (CT) features of intraperitoneal tuberculous abscess (IPTA). METHODS: Eight patients with IPTA confirmed by pathology were analyzed retrospectively. The clinical symptoms, medical images, and surgical findings were evaluated. Involvement of the intestine, peritoneum, viscera, and lymph nodes was also assessed. RESULTS: All 8 patients had a history of abdominal discomfort for 1 to 6 mo. Physical examination revealed a palpable abdominal mass in 6 patients. Three patients had no evidence of pulmonary tuberculosis (TB). All IPTAs (11 abscesses) were seen as a multiseptated, peripherally enhanced, hypodense mass with enlarged, rim-enhanced lymph nodes. The largest abscess diameter ranged from 4.5 cm to 12.2 cm. CT showed 2 types of IPTA: Lymph node fusion and encapsulation. Of the 8 patients, one had liver tuberculosis and one had splenic and ovarian tuberculosis. Two cases showed involvement of the terminal ileum and ileocecal junction. Ascites were found in 4 cases. Three patients had peritonitis and mesenteritis. Three patients showed involvement of the omentum. Three patients had histological evidence of caseating granuloma, and 5 had histological evidence of acid-fast bacilli. CONCLUSION: CT is crucial in the detection and characterization of IPTA. Certain CT findings are necessary for correct diagnosis. PMID:26435779

    Recurrent soft tissue abscesses of the jaw, wrist, and arm developed in a 73-year-old housewife with nephrotic syndrome and immunoglobulin A(κ) gammopathy of unknown etiology. Conventional cultures remained negative, despite visible gram-negative rods on microscopy. Broad-spectrum PCR revealed Legionella cincinnatiensis, which was confirmed by isolation of the organism on special Legionella medium. Infections due to Legionella species outside the lungs are rare. L. cincinnatiensis has been implicated in only four cases of clinical infection; these involved the lungs in three patients and the central nervous system in one patient. We conclude that broad-spectrum PCR can be a valuable tool for the evaluation of culture-negative infections with a high probability of bacterial origin and that Legionella might be an underdiagnosed cause of pyogenic soft tissue infection.

    The median waiting time for patients with MELD ≥ 35 decreased from 18 days in 2012 to 9 days in 2014, after implementation of the Share 35 policy in June 2013. Similarly, mortality among candidates listed with MELD ≥ 35 decreased from 366 per 100 waitlist years in 2012 to 315 in 2014. The number of new active candidates added to the pediatric liver transplant waiting list in 2014 was 655, down from a peak of 826 in 2005. The number of prevalent candidates (on the list on December 31 of the given year) continued to decline, 401 active and 173 inactive. The number of deceased donor pediatric liver transplants peaked at 542 in 2008 and was 478 in 2014. The number of living donor liver pediatric transplants was 52 in 2014; most were from donors closely related to the recipients. Graft survival continued to improve among pediatric recipients of deceased donor and living donor livers. PMID:26755264

    Acute appendicitis may occasionally become extraordinarily complicated and life threatening yet difficult to diagnose. One such presentation is described in a 60-year-old man who was brought to the hospital due to right lumbar pain and fever for the last 15 days. Ultrasonography showed a right perinephric gas and fluid collection. Abdominal computed tomography with multidetector-row CT (MDCT) revealed gas-containing abscess in the right retroperitoneal region involving the perinephric space, extending from the lower pole of the right kidney up to the bare area of the liver. Inflamed retrocecal appendix was seen on thick multiplanar reformat images with its tip at the lower extent of the abscess. Laparotomy and retroperitoneal exploration were performed immediately and a large volume of foul smelling pus was drained. A ruptured retrocecal appendix was confirmed as the cause of the abscess.

    Dental abscess is a frequently occurring infectious process known to the health practice. The fate of the infection depends on the virulence of the bacteria, host resistance factors, and regional anatomy. Serious consequences arising from the spread of a dental abscess lead to significant morbidity and mortality. Acute dental abscess is polymicrobial, comprising of strict anaerobes, such as anaerobic cocci, Prevotella, Fusobacterium species, and facultative anaerobes, such as viridans group streptococci and the Streptococcus anginosus group. Numerous novel, uncultivable and fastidious organisms have been identified as potential pathogens with the use of non-culture techniques. The majority of localized dental abscesses respond to surgical treatment while the use of antimicrobials is limited to severe spreading infections. There is a need for good-quality clinical trials of sufficient size to identify the ideal treatment. The microbiology of the acute dentoalveolar abscess and its treatment in the light of improved culture and diagnostic methods are reviewed. PMID:24348613

    Interleukin-1 receptor associated kinase 4 (IRAK-4) deficiency is a primary immunodeficiency that predisposes to opportunistic pyogenic infections in affected patients. The presentation can be variable, and the microbiological and immunologic management of this condition has been documented; however, the atypical nature of its presentation calls for a different approach in its surgical management. This is the first reported case of transcranial progression of a soft tissue abscess in a patient with IRAK-4 deficiency, with an emphasis on a multidisciplinary approach to treat infection at an extremely vulnerable anatomic site.

    Fungi are a relatively uncommon cause of brain abscess in neonates and early infancy. They are usually associated with predisposing factors like prematurity, low birth weight, use of broad-spectrum antibiotics, and prolonged stay in the intensive care unit. Candida tropicalis (C. tropicalis) is rapidly emerging as a nosocomial threat in the neonatal intensive care settings. This case report describes a neonate with C. tropicalis brain abscess who was diagnosed early and managed aggressively with a favorable outcome. Inadvertent use of intravenous antibiotics can have serious complications such as invasive fungal infection. Correct microbiological diagnosis is the key to successful treatment of deep-seated pyogenic infection. Fungal etiology should always be studied in relevant clinical settings. PMID:25506171

    This study evaluated the safety, feasibility, and clinical utility of transhepatic drainage of inaccessible abdominal abscesses retrospectively under real-time computed tomographic (CT) guidance. For abdominal abscesses, 12 consecutive patients received percutaneous transhepatic drainage. Abscesses were considered inaccessible using the usual access route because they were surrounded by the liver and other organs. The maximum diameters of abscesses were 4.6-9.5 cm (mean, 6.7 {+-} 1.4 cm). An 8-Fr catheter was advanced into the abscess cavity through the liver parenchyma using real-time CT fluoroscopic guidance. Safety, feasibility, procedure time, and clinical utility were evaluated. Drainage catheters were placed with no complications in abscess cavities through the liver parenchyma in all patients. The mean procedure time was 18.8 {+-} 9.2 min (range, 12-41 min). All abscesses were drained. They shrank immediately after catheter placement. In conclusions, this transhepatic approach under real-time CT fluoroscopic guidance is a safe, feasible, and useful technique for use of drainage of inaccessible abdominal abscesses.

    The virulent organism Staphylococcus aureus produced brain abscesses that were quantitatively and qualitatively different from those caused by less virulent organisms. S. aureus abscesses created larger lesions, as earlier ependymitis, delayed progress toward healing, and caused areas of inflammatory escape outside the collagen capsule. Imaging tests revealed similar findings: the abscesses were larger, had more extensive central necrosis, and showed earlier evidence of ependymitis. This virulent organism also demonstrated that white matter is more susceptible than overlying gray matter to destruction by infection. The pattern of spread and other histologic findings suggest that collagen capsule formation has less of an infection "containment" function than was previously thought. PMID:3085444

    A 60-year-old woman with colorectal adenocarcinoma underwent surgical mass resection in 2003; hepatic segmentectomy due to hepatic metastasis was performed in 2005. A port-a-cath for the administration of chemotherapy was cannulated. In April 2007, the patient developed fever and shivering, and the catheter was removed. Catheter and blood cultures were positive for methicillin-sensitive Staphylococcus aureus. TEE showed a very mobile mass (3 x 2 cm) at the junction of the posterior and anterior leaflets of the tricuspid valve. The mass had large echolucent areas inside, exhibiting an appearance like a 'ball of wool' (Panel B). Cardiac MRI confirmed the presence of a mass attached to the tricuspid valve, as shown in the delayed enhancement sequence. At surgery, a ruptured tendinous cord as well as a large abscess within the septal leaflet of the tricuspid valve was found. PMID:19196752

    Very few studies have so far been dedicated to the systematic analysis of protein interactions occurring between surface and/or secreted proteins in bacteria. Such interactions are expected to play pivotal biological roles that deserve investigation. Taking advantage of the availability of a detailed map of surface and secreted proteins in Streptococcus pyogenes (group A Streptococcus (GAS)), we used protein array technology to define the “surface interactome” in this important human pathogen. Eighty-three proteins were spotted on glass slides in high density format, and each of the spotted proteins was probed for its capacity to interact with any of the immobilized proteins. A total of 146 interactions were identified, 25 of which classified as “reciprocal,” namely, interactions that occur irrespective of which of the two partners was immobilized on the chip or in solution. Several of these interactions were validated by surface plasmon resonance and supported by confocal microscopy analysis of whole bacterial cells. By this approach, a number of interesting interactions have been discovered, including those occurring between OppA, DppA, PrsA, and TlpA, proteins known to be involved in protein folding and transport. These proteins, all localizing at the septum, might be part, together with HtrA, of the recently described ExPortal complex of GAS. Furthermore, SpeI was found to strongly interact with the metal transporters AdcA and Lmb. Because SpeI strictly requires zinc to exert its function, this finding provides evidence on how this superantigen, a major player in GAS pathogenesis, can acquire the metal in the host environment, where it is largely sequestered by carrier proteins. We believe that the approach proposed herein can lead to a deeper knowledge of the mechanisms underlying bacterial invasion, colonization, and pathogenesis. PMID:22199230

    Streptococcus pyogenes causes human infections ranging from mild pharyngitis and impetigo to serious diseases including necrotizing fasciitis and streptococcal toxic shock syndrome. The objective of this study was to compare molecular emm typing and pulsed field gel electrophoresis (PFGE) with multiple-locus variable-number tandem-repeat analysis (MLVA) for genotyping of Chinese S. pyogenes isolates. Molecular emm typing and PFGE were performed using standard protocols. Seven variable number tandem repeat (VNTR) loci reported in a previous study were used to genotype 169 S. pyogenes geographically-diverse isolates from China isolated from a variety of disease syndromes. Multiple-locus variable-number tandem-repeat analysis provided greater discrimination between isolates when compared to emm typing and PFGE. Removal of a single VNTR locus (Spy2) reduced the sensitivity by only 0.7%, which suggests that Spy2 was not informative for the isolates screened. The results presented support the use of MLVA as a powerful epidemiological tool for genotyping S. pyogenes clinical isolates. PMID:25843529

On clinical examination the patient was found to have tenderness of the cervical and the lumbar spine with great motion restriction. The blood tests revealed high erythrocyte sedimentation rate and C-reactive protein, abnormal liver function tests and a positive rheumatoid factor. Serological test for Brucella was positive while cervical MRI revealed epidural abscess and spondylodiscitis. Conservative treatment with streptomycin (it was substituted by rifampicin after the third week) and doxycyclin for 4 months significantly improved her symptoms. The frequency as well as the diagnosis and management of this manifestation are discussed. PMID:23188848

    Iliopsoas abscess is usually secondary to the spread of infection from a contiguous focus. Primary disease is uncommon, except in children where Staphylococcus aureus is the main pathogen. We report a 60-year-old woman who developed a primary iliopsoas abscess as a result of haematogenous spread of Capnocytophaga sputigena from a palatal fistula and chronic sinusitis due to previous treatment for nasopharyngeal carcinoma. Pyomyositis due to unusual and fastidious Gram-negative bacilli should be considered in patients with head and neck tumours who have previously received radiotherapy. PMID:20634330

    Three cases of pyogenic sacroiliitis are described, and the English literature from 1878 to 1990 reviewed, for a total of 166 cases. In 1 patient the source of infection was identified at the site of an intravenous line; 1 patient had 2 risk factors for developing the disease (pregnancy and intravenous drug use); and a third patient had no source of infection and no associated risk factors. The diagnosis of pyogenic sacroiliitis was made in each patient by history, physical examination, and positive skeletal scintigraphy or computed tomography of the sacroiliac joint. The infectious agent causing septic arthritis was identified by fine-needle aspiration of the sacroiliac joint under fluoroscopic guidance. Two of the 3 patients also had an open biopsy of the sacroiliac joint--one to confirm the organism causing septic arthritis, and the other for surgical drainage of the infected sacroiliac joint. Cultures from all 3 patients grew organisms uncommon for this disease, and all were treated for 6 weeks with intravenous antibiotics. In all patients pain diminished after treatment. Pyogenic sacroiliitis is a relatively rare condition (1-2 cases reported/year) that may be clinically difficult to diagnose unless the clinician is familiar with the disease. A prompt diagnosis can prevent significant morbidity and reduce serious complication. Major predisposing factors include intravenous drug use, trauma, or an identifiable focus of infection elsewhere, but 44% of patients have no predisposing or associated factors identified. Most patients present with an acute febrile illness with pain in the buttocks and pain on movement that stresses the affected sacroiliac joint. There is no specific blood test which points to the diagnosis of pyogenic sacroiliitis, although the erythrocyte sedimentation rate may be greater than 100 mm/hr. The diagnostic procedure of choice is bone scan with attention to the early perfusion phase, which usually localizes the affected sacroiliac joint

    An 81-year-old man was referred to our institution for evaluation of high fever and a liver tumor that had been detected by ultrasonography. Computed tomography revealed a low-density mass with peripheral ring-like enhancement in S5 of the liver. The liver mass was in contact with the gallbladder, and the boundary between the mass and the gallbladder was unclear. On the suspicion of liver abscess, percutaneous transhepatic drainage was performed. The cavity of the abscess communicated with the gallbladder. Because the cavity had no tendency to reduce in size, we performed surgical resection under a preoperative diagnosis of liver abscess or primary liver carcinoma invading to the gallbladder. Intraoperative findings revealed a liver tumor invading the transverse colon and gallbladder. Subsegmentectomy of S4a and S5 of the liver combined with gallbladder and transverse colon resection was performed. Histopathological findings indicated the growth of a mass forming type intrahepatic cholangiocarcinoma with invasion to the transverse colon and gallbladder, and the pathological stage of the tumor was pT3N0M0, fStage Ⅲ. Thus far, the patient is alive without recurrence 9 months after surgery. Here, we report an extremely rare case of intrahepatic cholangiocarcinoma that invaded other organs and was associated with an intra-tumor abscess. PMID:26805160

    The capsule of Streptococcus pyogenes serves as an adhesin as well as an anti-phagocytic factor by binding to CD44 on keratinocytes of the pharyngeal mucosa and the skin, the main entry sites of the pathogen. We discovered that S. pyogenes HSC5 and MGAS315 strains are further thermoregulated for capsule production at a post-transcriptional level in addition to the transcriptional regulation by the CovRS two-component regulatory system. When the transcription of the hasABC capsular biosynthetic locus was de-repressed through mutation of the covRS system, the two strains, which have been used for pathogenesis studies in the laboratory, exhibited markedly increased capsule production at sub-body temperature. Employing transposon mutagenesis, we found that CvfA, a previously identified membrane-associated endoribonuclease, is required for the thermoregulation of capsule synthesis. The mutation of the cvfA gene conferred increased capsule production regardless of temperature. However, the amount of the capsule transcript was not changed by the mutation, indicating that a post-transcriptional regulator mediates between CvfA and thermoregulated capsule production. When we tested naturally occurring invasive mucoid strains, a high percentage (11/53, 21%) of the strains exhibited thermoregulated capsule production. As expected, the mucoid phenotype of these strains at sub-body temperature was due to mutations within the chromosomal covRS genes. Capsule thermoregulation that exhibits high capsule production at lower temperatures that occur on the skin or mucosal surface potentially confers better capability of adhesion and invasion when S. pyogenes penetrates the epithelial surface.

    Streptococcus pyogenes is commonly believed to be resistant to trimethoprim-sulfamethoxazole (SXT), resulting in reservations about using SXT for skin and soft tissue infections (SSTI) where S. pyogenes is involved. S. pyogenes' in vitro susceptibility to SXT depends on the medium's thymidine content. Thymidine allows S. pyogenes to bypass the sulfur-mediated inhibition of folate metabolism and, historically, has resulted in apparently reduced susceptibility of S. pyogenes to sulfur antibacterials. The low thymidine concentration in Mueller-Hinton agar (MHA) is now regulated. We explored S. pyogenes susceptibility to SXT on various media. Using two sets of 100 clinical S. pyogenes isolates, we tested for susceptibility using SXT Etests on MHA containing defibrinated horse blood and 20 mg/liter β-NAD (MHF), MHA with sheep blood (MHS), MHA alone, MHA with horse blood (MHBA), and MHA with lysed horse blood (MHLHBA). European Committee on Antibacterial Susceptibility Testing (EUCAST) breakpoints defined susceptibility (MIC, ≤ 1 mg/liter) and resistance (MIC, >2 mg/liter). In study 1, 99% of S. pyogenes isolates were susceptible to SXT on MHA, MHBA, and MHLHBA, with geometric mean MICs of 0.04, 0.04, and 0.05 mg/liter, respectively. In study 2, all 100 S. pyogenes isolates were susceptible to SXT on MHF, MHS, MHA, and MHLHBA with geometric mean MICs of 0.07, 0.16, 0.07, and 0.09 mg/liter, respectively. This study confirms the in vitro susceptibility of S. pyogenes to SXT, providing support for the use of SXT for SSTIs. A clinical trial using SXT for impetigo is ongoing. PMID:23052313

    Six patients with bacteriologically proven pyogenic osteomyelitis of the spine were followed serially with computed tomography (CT). Initial evaluation of the involved vertebral bodies and adjacent soft tissues showed a drop in CT numbers when compared to normal cancellous bone and soft tissues. A soft-tissue mass was seen in all cases. After appropriate antibiotic therapy, all six patients showed an increase in bone density and a diminution of the soft-tissue mass (p < 0.05). Five of the six patients showed a further decrease in soft-tissue CT numbers.

  10. Ovarian Abscess Following Therapeutic Insemination

    Background: Artificial insemination is a commonly performed procedure for the treatment of various forms of infertility. Infectious complications have only rarely been noted as a complication of intrauterine insemination (IUI). Case: In this presentation, we report the first case of an ovarian abscess following IUI with the husband's semen. Despite treatment with triple antibiotics, an oophorectomy was required. Surgical as well as pathological evaluation confirmed the diagnosis of an ovarian abscess. Following surgery, the patient responded well to antibiotic therapy. Conclusion: Since pelvic infections are ascending processes, the violation of the natural cervical barrier with IUI can theoretically place the patient at increased risk for this complication. While few advocate routine cultures of semen samples, the clinician must be acutely alert to potential infectious morbidity following this procedure. Early diagnosis and intervention are necessary to minimize morbidity and optimize treatment. PMID:18472883

    Mucocutaneous lymph node syndrome, Kawasaki disease, is a potentially fatal pediatric disease characterized by prolonged high fever, conjunctivitis, stomatitis. myocarditis, aseptic meningitis and coronary artery vasculitis. We present peritonsillar abscess as a previously unreported otolaryngologic symptom and presentation of Kawasaki disease. A previously healthy 7-year-old boy required hospitalization for a peritonsillar abscess. Despite adequate surgical drainage and appropriate intravenous antibiotics, the patients' systemic symptoms persisted. After the week of hospitalization, the child was transferred to the intensive care unit with acute myocarditis, heart failure and severe arthritis. The diagnosis of Kawasaki disease was confirmed with echocardiographic evidence of coronary artery aneurysms and the development of the characteristic hand and foot desquamation. The patient's symptoms resolved with salicylates and intravenous gamma globulin therapy. He was discharged in good condition after 3 weeks of hospitalization. This is the first report of Kawasaki syndrome presenting with peritonsillar abscess. Although we discuss a unique presentation of this disease. Kawasaki syndrome often exhibits other otolaryngologic findings early in its course. A literature review of the clinical characteristics, pathogenesis and therapy of this disease is presented.

    Non-resolving pneumonia leading to lung abscess is always a challenge to the treating physician especially in a diabetic patient. Atypical radiological features of lung abscess should raise the suspicion of unusual organisms. This is a case report of a 42 year old diabetic male presented with features suggestive of lung abscess and multiple target organ damage. Subsequent work up revealed that the etiological agent is a rare fungus - Basidiobolus. To the best of our knowledge this is the first case of Basidiobolus lung abscess reported from India.

    Odontogenic origins are rarely implicated in the formation of brain abscesses. The relative paucity of this kind of infection and the difficulty in matching the causative microorganisms of a brain abscess to an odontogenic source can explain the late management of patients. We herein describe a case of a 46-year-old man with a cerebellar abscess that was probably due to an odontogenic infection. The diagnosis supported by imaging and microscopic identification, mini craniectomy for abscess drainage followed by eradication of all potential dental infectious foci, and an antibiotic regimen based on cephalosporins, metronidazole, and vancomycine contributed to a successful outcome.

    Beginning in 1990, gram-positive rods resembling Actinomyces pyogenes were found with increasing frequency in mixed cultures from various infectious processes, most of them from patients with otitis, empyema, pilonidal cysts, perianal abscesses, and decubitus ulcers. Ribotyping and hybridization showed that these gram-positive rods could be divided into five groups not related to known Actinomyces species. Biochemical markers for reliable differentiation into these groups, however, could not be found. Therefore, naming new species is not warranted unless parameters are discovered that allow identification without DNA hybridization. These gram-positive rods have been isolated only in mixed cultures with anaerobes, Staphylococcus aureus, Streptococcus "milleri," enterococci, and gram-negative rods. Their exact role in these possibly synergistic infections needs further investigation. Images PMID:8501213

    Some common agents were tested for their effectiveness against Corynebacterium pyogenes. The pathogen proved most susceptable to Wofasteril. All germs were killed within ten minutes by a 0.005% solution. Equally good action was recorded from all the other tested agents as well (lactic acid, Lugol's solution, formalin, cupric sulphate, alcohol, and aethacridine. Other studies were conducted with the view to testing the survival capacity of Corynebacterium pyogenes in different media and storage conditions. The pathogen survived three months in routine media and mastitis secretion at room temperature. Regrowth of 38 in 50 strains took place after nine months of refrigerator storage in slanting blood agar tubes with paraffin plugs. Germs sampled from mastitis secretion and stored in a refrigerator were cultivable even after one year had elapsed. The detectability rate of Corynebacterium pyogenes did not change over months by storage of wound infection material at 12 degrees C below zero. The pathogen remained detectable five days from artificial contamination of cattle skin. PMID:336001

    A 48-year-old man presented to the emergency department with complain of severe neck pain and anterior chest pain. Intermittent fever in the recent 2 days was also noted. There is a track maker over his left side of neck. The laboratory examination showed leukocytosis and high C-reactive protein level. Urine drug screen was positive for opiate. Empirical antibiotic administration was given. Blood culture grew gram-positive cocci in chain, and there was no vegetation found by heart echocardiogram. However, progressive weakness of four limbs was noted, and patient even cannot stand up and walk. The patient also complained of numbness sensation over bilateral hands and legs, and lower abdomen. Acute urine retention occurred. We arranged magnetic resonance imaging survey, which showed evidence of inflammatory process involving the retropharyngeal spaces and epidural spaces from the skull base to the bony level of T5. Epidural inflammatory process resulted in compression of the spinal cord and bilateral neural foramen narrowing. Neurosurgeon was consulted. Operation with laminectomy and posterior fusion with bone graft and internal fixation was done. Culture of epidural abscess and 2 sets of blood culture all yielded methicillin-sensitive Staphylococcus aureus. For epidural abscess, the most common involved spine is lumbar followed by thoracic and cervical spine. Diagnosis and treatment in the drug abusers are still challenging because they lack typical presentation, drug compliance, and adequate follow-up and because it is hard to stop drug abuser habit. Significant improvement of neurological deficit can be expected in most spinal abscess in drug abusers after treatment. PMID:26298050

    Acute apical abscess is the most common form of dental abscess and is caused by infection of the root canal of the tooth. It is usually localized intraorally, but in some cases the apical abscess may spread and result in severe complications or even mortality. The reasons why dental root canal infections can become symptomatic and evolve to severe spreading and sometimes life-threatening abscesses remain elusive. Studies using culture and advanced molecular microbiology methods for microbial identification in apical abscesses have demonstrated a multispecies community conspicuously dominated by anaerobic bacteria. Species/phylotypes commonly found in these infections belong to the genera Fusobacterium, Parvimonas, Prevotella, Porphyromonas, Dialister, Streptococcus, and Treponema. Advances in DNA sequencing technologies and computational biology have substantially enhanced the knowledge of the microbiota associated with acute apical abscesses and shed some light on the etiopathogeny of this disease. Species richness and abundance and the resulting network of interactions among community members may affect the collective pathogenicity and contribute to the development of acute infections. Disease modifiers, including transient or permanent host-related factors, may also influence the development and severity of acute abscesses. This review focuses on the current evidence about the etiology and treatment of acute apical abscesses and how the process is influenced by host-related factors and proposes future directions in research, diagnosis, and therapeutic approaches to deal with this disease.

    The authors describe four cases of obturator internus muscle (OIM) abscess in children, including their clinical presentations and treatment. This was a retrospective chart review. Children and adolescents younger than 18 years discharged between July 1, 1985, and September 30, 1998, from Brenner Children's Hospital with the diagnosis of muscle abscess or pelvic abscess were identified. A total of 56 patients were identified with the diagnosis of muscle abscess or pelvic abscess. OIM abscess was defined by radiologic findings of an inflammatory process with fluid collection in the OIM, along with the clinical findings suggestive of an OIM abscess. Four of the patients met the definition of OIM muscle abscess. The common presenting features were fever, limp, and hip pain. Computed tomography or magnetic resonance imaging was diagnostic in all four patients, and Staphylococcus aureus was the causative agent in each. All the patients recovered, one after surgical drainage and the other three after antimicrobial therapy alone or with needle aspiration. The presentation of OIM pyomyositis is similar to that of psoas muscle pyomyositis and other infectious processes of the pelvis and hip. The S. aureus is the most common etiologic agent but not the only one reported. Most patients can be managed without open surgical drainage, but needle aspirations may be helpful both therapeutically and diagnostically. PMID:11675547

Patients had been diagnosed with alcoholic liver cirrhosis and gastric varices bleeding and received a Histoacryl® injection for the variceal bleeding. Patients had fever and abdominal tenderness and were diagnosed with an adrenal abscess at 2 months following the Histoacryl® injection. One patient received open drainage and the other underwent percutaneous drainage. When a patient has previously been injected with Histoacryl® for the treatment of variceal bleeding and presents with fever, an evaluation for an unusual complication such as adrenal abscess is recommended.

    Pyogenic flexor tenosynovitis is an orthopedic emergency most commonly caused by Staphylococcus aureus and streptococci and occasionally, when associated with water exposure, Mycobacterium marinum. Shewanella algae, a gram-negative bacillus found in warm saltwater environments, has infrequently been reported to cause serious soft tissue infections and necrosis. In this case, S. algae caused complicated flexor tenosynovitis requiring open surgical irrigation and debridement. Flexor tenosynovitis caused by S. algae rapidly presented with all 4 Kanavel cardinal signs as well as subcutaneous purulence, ischemia, and necrosis, thus meeting the requirements for Pang et al group III classification of worst prognosis. Because of its rarity and virulence, S. algae should always be considered in cases of flexor tenosynovitis associated with traumatic water exposure to treat and minimize morbidity appropriately.

    Pyogenic granuloma is thought to represent an exuberant tissue response to a local irritation or trauma. It is a reactional response to constant minor trauma and it might be related to hormonal changes. Clinically, these lesions usually present as single nodules or sessile papules with smooth or lobulated surfaces. These may be seen in any size, from a few millimetres to several centimetres. Pyogenic granuloma of the oral cavity is known to involve the gingiva more commonly (75% of all the cases). An extragingival occurrence of pyogenic granuloma is rare. This paper has described an extragingival pyogenic granuloma which occurred on the upper labial mucosa in a 30 years old female patient. PMID:23905151

    Acute lingual abscess is a rare yet life-threatening clinical entity. Lingual abscess must be appropriately diagnosed and treated in the emergency department to avoid acute airway compromise. A 68-year-old woman on immunomodulatory medication for rheumatoid arthritis presented to the emergency department with left facial pain and swelling. An anterior lingual abscess was diagnosed on computed tomographic scan. The most common cause of lingual abscess is direct trauma, although immunocompromised state is a predisposing risk factor. Intravenous antibiotics are the primary treatment modality, with consideration given to adjunctive surgical drainage. We present this case to increase awareness surrounding this diagnosis among emergency physicians. Spontaneous lingual abscess should be considered in immunocompromised patients who present to the emergency department with tongue pain and edema even in the absence of lingual trauma. PMID:24332904

    We describe the rare occurrence of an Actinomyces meyeri cerebral abscess in a 55-year-old woman following a dental extraction. This patient presented with a 2-day history of hemisensory loss, hyper-reflexia and retro-orbital headache, 7 days following a dental extraction for apical peridonitis. Neuroimaging showed a large left parietal abscess with surrounding empyema. The patient underwent craniotomy and drainage of the abscess. A. meyeri was cultured. Actinomycosis is a rare cause of cerebral abscess. The A. meyeri subtype is particularly rare, accounting for less than 1% of specimens. This case describes an unusually brief course of the disease, which is usually insidious. Parietal lobe involvement is unusual as cerebral abscesses usually have a predilection for the frontal and temporal regions of the brain. Although there are no randomised trials to guide therapy, current consensus is to use a prolonged course of intravenous antibiotics, followed by 6-12 months of oral therapy. PMID:25870213

    Nerve abscess is an infrequently reported complication of leprosy. We describe a patient with a pure neuritic type of leprosy with multiple nerve abscesses, who presented with tingling and numbness in the medial aspect of his right forearm and hand. Subsequently he developed pain, redness and swelling over the medial side of his right elbow and the flexor aspect of his right wrist. High-resolution ultrasound showed diffuse thickening of the right ulnar nerve with hypoechoic texture housing a cystic lesion with internal debris suggesting an abscess, at the cubital tunnel. Histopathological examination of the pus and tissue obtained from the abscess revealed presence of granulomas with lepra bacilli. The patient responded to surgery and multidrug therapy. In conclusion, the nerve abscess as the first manifestation of leprosy is uncommon and a high index of suspicion is required to make a correct diagnosis. PMID:24171239

    Enterobacteriaceae is a leading pathogen of community-onset bacteremia. This study aims to establish a predictive scoring algorithm to identify adults with community-onset Enterobacteriaceae bacteremia who are at risk for abscesses. Of the total 1262 adults, 152 (12.0%) with abscess occurrence were noted. The 6 risk factors significantly associated with abscess occurrence-liver cirrhosis, diabetes mellitus, thrombocytopenia and high C-reactive protein (>100 mg/L) at bacteremic onset, delayed defervescence, and bacteremia-causing Klebsiella pneumoniae-were each assigned +1 point to form the scoring algorithm. In contrast, the elderly, fatal comorbidity (McCabe classification), and bacteremia-causing Escherichia coli were each assigned -1 point, owing to their negative associations with abscess occurrence. Using the proposed scoring algorithm, a cut-off value of +1 yielded a high sensitivity (85.5%) and an acceptable specificity (60.4%). Although the proposed predictive model needs further validation, this simple scoring algorithm may be useful for the early identification of abscesses by clinicians. PMID:26456388

    We herein report a rare case of pyogenic vertebral osteomyelitis (PVO) coexisting with breast carcinoma. A 71-year-old female presented with neck pain without fever. Magnetic resonance imaging (MRI) showed suspected metastatic lesions in her neck (C7 and Th1). Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased FDG uptake in the neck spines and in the left breast. A core needle biopsy of the left breast revealed the presence of invasive ductal carcinoma. Our first tentative diagnosis of the patient was left breast carcinoma with bone metastases, and first-line endocrine therapy was started. However, surgical intervention for the spines had to be considered, because her neurological symptoms progressed. A repeated MRI scan showed a narrowing of the disc space and fluid accumulation around the vertebrae. This suggested the presence of PVO rather than metastases. Surgery confirmed the presence of PVO in C7 and Th1, and a culture of the abscess yielded Escherichia coli. The patient's neurological symptoms dramatically improved after surgery. Breast conserving surgery was performed 3 months after the surgery for PVO. The patient is well and has no clinical evidence of disease 18 months after the breast conserving surgery. PVO is rare, but should be included in the differential diagnosis in patients presenting with early breast carcinoma. PMID:22382854

    There are no satisfactory animal models for the study of anaerobic lung abscess. Aspiration of food, gastric mucin, or hydrochloric acid, or any combination of these, along with oropharyngeal bacteria, is commonly believed to cause aspiration pneumonia and lung abscess. In the animal model described, none of the adjuvants was effective in producing anaerobic lung abscesses. Anaerobic bacteria derived from dental scrapings of a healthy adult (Peptococcus morbillorum, Fusobacterium nucleatum, Eubacterium lentum, and Bacteroides fragilis), when inoculated transtracheally without any adjuvants into New Zealand male white rabbits, consistently produced lung abscesses. Neither B fragilis by itself nor a mixture of P. morbillorum, F. nucleatum, and E. lentum without the addition of B. fragilis produced lung abscesses. The bacterial isolates used in this study were stored in prereduced chopped-meat-glucose medium and subcultured several times and were found effective in reproducing anaerobic lung abscesses repeatedly. This animal model is suitable for the study of pathogenesis, diagnosis, and treatment of B. fragilis-associated anaerobic lung abscess. Images PMID:7216463

There were very few reports about urinary tract infections such as renal abscess, perinephric abscess, and emphysematous pyelonephritis complicated with psoas muscle abscess; however, psoas muscle abscess associated with emphysematous cystitis has not yet been reported. Here, we report a case of bilateral posas muscle abscess following emphysematous cystitis in an 81-year-old nondiabetic man, who was treated successfully with prolonged antibiotic therapy and supportive care. Early recognition of psoas muscle abscess can prevent aggressive interventional procedure and warrant good prognosis. PMID:25755669

    Streptococcus pyogenes is the most common bacterial pathogen causing pharyngotonsillitis, and also can lead to diseases such as otitis media, impetigo, necrotizing fasciitis, bacteremia, sepsis and toxic shock-like syndrome. M protein encoded by emm gene is an important virulence factor of S.pyogenes and it is used for genotyping in epidemiological studies. The aims of this study were to determine the M protein types of group A streptococci (GAS) by using emm gene sequence analysis method, to compare the M types in terms of analogy with the vaccine in development and to determine the antibiotic susceptibilities of the isolates. A total of 35 GAS strains isolated from various clinical specimens in our laboratory were included in the study. Strains growing in blood culture were considered as invasive, strains growing in throat and abscess cultures were considered as non-invasive. The isolates have been identified by conventional methods and 16S rRNA sequence analysis at species level. emm genotyping of strains identified as S.pyogenes, was performed by PCR method as proposed by the CDC. Amplicons were obtained and sequenced in 23 out of 35 isolates. The results were compared with CDC emm sequence database. Antibiotic susceptibility of the isolates was performed by agar dilution method and evaluated as recommended by CLSI. Twenty-three out of 35 isolates could be typed and 15 different emm genotypes were detected. The most common emm types were emm1 (22%), emm89 (13%), emm18 (9%) and emm19 (9%). The detection rate of other emm types (emm5, 12, 14, 17, 26, 29, 37, 74, 78, 92, 99) was 47%. Types emm1, 12, 19, 74, 89 and 99 were observed in strains isolated from blood cultures.

    We report an unusual case of brain aspergillosis with multiple recurrent abscess in a 40 year-old immunocompetent woman, with good therapeutical outcome. The patient presented a subarachnoid hemorrhage caused by a ruptured pericallosal artery aneurysm and was submitted to a craniotomy for aneurysm surgery. Five months later, she developed multiple Aspergillus cerebral abscess. Two craniotomies and amphotericin B became necessary during treatment. Fourteen years later, she is asymptomatic. Treatment of brain aspergillosis abscess implied the combination of both surgical and drug therapy with amphotericin B. PMID:16400435

  20. The role of coagulation/fibrinolysis during Streptococcus pyogenes infection

    The hemostatic system comprises platelet aggregation, coagulation and fibrinolysis and is a host defense mechanism that protects the integrity of the vascular system after tissue injury. During bacterial infections, the coagulation system cooperates with the inflammatory system to eliminate the invading pathogens. However, pathogenic bacteria have frequently evolved mechanisms to exploit the hemostatic system components for their own benefit. Streptococcus pyogenes, also known as Group A Streptococcus, provides a remarkable example of the extraordinary capacity of pathogens to exploit the host hemostatic system to support microbial survival and dissemination. The coagulation cascade comprises the contact system (also known as the intrinsic pathway) and the tissue factor pathway (also known as the extrinsic pathway), both leading to fibrin formation. During the early phase of S. pyogenes infection, the activation of the contact system eventually leads to bacterial entrapment within a fibrin clot, where S. pyogenes is immobilized and killed. However, entrapped S. pyogenes can circumvent the antimicrobial effect of the clot by sequestering host plasminogen on the bacterial cell surface that, after conversion into its active proteolytic form, plasmin, degrades the fibrin network and facilitates the liberation of S. pyogenes from the clot. Furthermore, the surface-localized fibrinolytic activity also cleaves a variety of extracellular matrix proteins, thereby enabling S. pyogenes to migrate across barriers and disseminate within the host. This review summarizes the knowledge gained during the last two decades on the role of coagulation/fibrinolysis in host defense against S. pyogenes as well as the strategies developed by this pathogen to evade and exploit these host mechanisms for its own benefit.

    We present the case of poor neurological recovery and subsequent death secondary to a thalamic abscess in a 53-year-old man. This patient initially presented with sudden dysarthria and left hemiparesis while driving. Neuroimaging showed a multilobular abscess involving the right thalamus with oedema extending to the basal ganglionic region and brainstem. The source of the abscess was initially unknown and it required draining multiple times while the different causes were being explored. The patient's neurological state along with intubation made for a difficult and inconclusive oral examination. It was only after neuroimaging included tooth-bearing areas that it became evident that this patient had extensive periodontal disease with multiple areas of periapical radiolucencies. The patient underwent complete dental clearance alongside repeated drainage of the abscess. Despite initial postoperative improvement, the patient never recovered from the neurological damage and died 3 weeks later. PMID:26678690

    Brain abscess is an uncommon but a compelling reality in neurosurgical practice. Its focal, local, and systemic manifestations conceal its infective and obsessive nature. There are many a lesson that a brain abscess, as a bio-phenomenon, offers to the medical fraternity in general and the neurosurgeons, in particular. From Skt. puyati = to stink, comes the word "pus," meaning something foul, putrid, or rotten. From ab = away, and cedre = to go, comes the term "abscess" which is but nature's ingenious way of creating a fluid-filled cavity that will eventually rupture to an exterior to get rid of the non-self contents and proceed to healing. A brain abscess is special in the sense that it is, in general, more solid than fluid for reasons the human body and brain know best. PMID:26053804

    Pyogenic granuloma is a reactive hyperplasia of connective tissue in response to local irritants. It is a tumourlike growth of the oral cavity, frequently located surrounding the anterior teeth or skin that is considered to be neoplastic in nature. It usually arises in response to various stimuli such as low-grade local irritation, traumatic injury, hormonal factors, or certain kinds of drugs. Histologically, the surface epithelium may be intact, or may show foci of ulcerations or even exhibiting hyperkeratosis. It overlies a mass of dense connective tissue composed of significant amounts of mature collagen. Gingiva is the most common site affected followed by buccal mucosa, tongue and lips. Pyogenic granuloma in general, does not occur when excised along with the base and its causative factors. This paper presents some cases of a pyogenic granuloma managed by surgical intervention.

    A commercially available biochemical test panel, commercially available diagnostic tablets and gas-liquid chromatography (GLC) of cellular fatty acids were used to find out whether Arcanobacterium haemolyticum and Actinomyces pyogenes could be further differentiated from each other. Xylitol and alpha-methyl-D-glucoside fermentation, Voges-Proskauer reaction and tributyrate hydrolysis were found to be useful additional tests which differentiated Arc. haemolyticum and A. pyogenes. GLC analysis revealed major differences in the cellular 16:0, 18:2(9,12) and 18:1(9) fatty acid composition of the two species. Especially the Voges-Proskauer test available as diagnostic tablets can be easily performed in clinical microbiology laboratories, in addition to the tests now used to differentiate Arc. haemolyticum from A. pyogenes.

    Background Deep eosinophilic granulomatous abscesses, as distinguished from eosinophilic subcutaneous abscesses, are rare. Most reports are from the Far-East and India where the most commonly attributed cause is Toxocara. Sulaimaniyah in Northeastern Iraq has experienced an outbreak of eosinophilic granulomatous liver and gastrointestinal (GI) abscesses beginning in 2009. The purpose of this study was to determine the etiology and guide treatment. Methods The study was an ongoing investigation of patients having a histopathologic diagnosis of eosinophilic granulomatous abdominal abscesses in Sulaimaniyah hospitals from May 2009 to August 2012. Tissues were examined for organisms, and Enzyme Linked Immunoabsorbent Assays (ELISA) were performed for serum antibodies to Fasciola hepatica, Toxocara, and Echinococcus granulosus. Results Fourteen patients had granulomatous inflammation surrounding a central necrotizing eosinophilic exudate identified in surgical pathology specimens from abdominal surgeries. Two children and four adults had abscesses that formed GI masses. These patients included a 39 year old male with oropharyngeal and transverse colon disease, and a 48 year old male with liver and GI abscesses. All sites demonstrated a Zygomycete fungus surrounded by eosinophilic Splendori-Hoeppli material consistent with basidiobolomycosis. Five of the six patients with fungal disease were treated by surgery and 4 to 7 months of itraconozol. One child died of intestinal perforation while receiving IV amphotericin B; two adults required additional surgery for recurrent GI obstruction. Eight patients had isolated liver abscesses with no organisms identified by histopathology: ELISA results for F. hepatica were positive for five, borderline for one, and negative for two patients. These eight patients were treated for fascioliasis by surgical resection of localized abscesses and albendazol. One patient serologically positive for F. Hepatica was found to have a common duct

    Pyogenic granuloma is one of the inflammatory hyperplasia seen in the oral cavity. The term is a misnomer because it is not related to infection and arises in response to various stimuli such as low-grade local irritation, traumatic injury, or hormonal factors. It is most commonly seen in females in their second decade of life due to vascular effects of hormones. Although excisional surgery is the treatment of choice for it, this paper presents the safest and most minimally invasive procedure for the regression of pyogenic granuloma. PMID:22567459

    Streptococcus pyogenes is an important global pathogen, causing considerable morbidity and mortality, especially in low and middle income countries where rheumatic heart disease and invasive infections are common. There is a number of promising vaccine candidates, most notably those based on the M protein, the key virulence factor for the bacterium. Vaccines against Streptococcus pyogenes are considered as impeded vaccines because of a number of crucial barriers to development. Considerable effort is needed by key players to bring current vaccine candidates through phase III clinical trials and there is a clear need to develop a roadmap for future development of current and new candidates.

    Influenza virus infections are associated with a significant number of illnesses and deaths on an annual basis. Many of the deaths are due to complications from secondary bacterial invaders, including Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, and Streptococcus pyogenes. The β-hemolytic bacteria S. pyogenes colonizes both skin and respiratory surfaces, and frequently presents clinically as strep throat or impetigo. However, when these bacteria gain access to normally sterile sites, they can cause deadly diseases including sepsis, necrotizing fasciitis, and pneumonia. We previously developed a model of influenza virus:S. pyogenes super-infection, which we used to demonstrate that vaccination against influenza virus can limit deaths associated with a secondary bacterial infection, but this protection was not complete. In the current study, we evaluated the efficacy of a vaccine that targets the M protein of S. pyogenes to determine whether immunity toward the bacteria alone would allow the host to survive an influenza virus:S. pyogenes super-infection. Our data demonstrate that vaccination against the M protein induces IgG antibodies, in particular those of the IgG1 and IgG2a isotypes, and that these antibodies can interact with macrophages. Ultimately, this vaccine-induced immunity eliminated death within our influenza virus:S. pyogenes super-infection model, despite the fact that all M protein-vaccinated mice showed signs of illness following influenza virus inoculation. These findings identify immunity against bacteria as an important component of protection against influenza virus:bacteria super-infection. PMID:25077423

    ABSTRACT This study retrospectively analyzed 12 patients with brain abscesses. Half of the patients were diagnosed inaccurately in the initial stage, and 7.2 days were required to achieve the final diagnosis of brain abscess. The patients presented only with a moderately elevated leukocyte count, serum CRP levels, or body temperatures during the initial stage. These markers changed, first with an increase in the leukocyte count, followed by the CRP and body temperature. The degree of elevation tended to be less prominent, and the time for each inflammatory index to reach its maximum value tended to be longer in the patients without ventriculitis than in those with it. The causative organisms of a brain abscess were detected in 10 cases. The primary causative organisms from dental caries were Streptococcus viridians or milleri, and Fusobacterium nucleatum. Nocardia sp. or farcinica were common when the abscess was found in other regions. The primary causative organisms of unrecognized sources of infection were Streptococcus milleri and Prolionibacterium sp. Nocardia is resistant to many antibiotics. However, carbapenem, tetracycline and quinolone were effective for Nocardia as well as many other kinds of bacteria. In summary, the brain abscesses presented with only mildly elevated inflammatory markers of body temperature, leukocyte and CRP. These inflammatory markers were less obvious in the patients without ventriculitis and/or meningitis. The source of infection tended to suggest some specific primary causative organism. It was reasonable to initiate therapy with carbapenem. PMID:23092104

    Background. Pyogenic granuloma is a reactive tumor-like lesion commonly affecting the oral cavity. These lesions usually appear as localized solitary nodule with a sessile or pedunculated base and colour varying from red, purplish, or pink, depending on the vascularity of the lesion. Pyogenic granuloma shows predilection for gingiva and is usually slow growing, but at times it shows rapid growth. The natural course of this lesion can be categorized into three distinct phases, namely, (i) cellular phase, (ii) capillary phase/vascular phase, and (iii) involutionary phase. Histopathologically, pyogenic granuloma is classified into lobular capillary hemangioma (LCH) and non-lobular capillary hemangioma (non-LCH). Case Presentation. In this series, four cases (varied age groups and both genders) of pyogenic granuloma showing varying histopathological presentation in relation to its clinical course have been described. The lesion in its early phase reveals diffuse endothelial cells, with few budding into capillaries. Among the capillary phase, the LCH type shows numerous blood vessels organized into lobular aggregates whereas the non-LCH type does not show any such organization and resembles granulation tissue. The involutionary phase shows healing of the lesion and is characterized by extensive fibrosis in the connective tissue. Conclusion. In conclusion, knowledge of the various histopathological presentation of this lesion is necessary for proper identification. PMID:27382492

    The past 2 decades have brought worrying increases in severe Streptococcus pyogenes diseases globally. To investigate and compare the epidemiological patterns of these diseases within Europe, data were collected through a European Union FP-5-funded program (Strep-EURO). Prospective population-based surveillance of severe S. pyogenes infection diagnosed during 2003 and 2004 was undertaken in 11 countries across Europe (Cyprus, the Czech Republic, Denmark, Finland, France, Germany, Greece, Italy, Romania, Sweden, and the United Kingdom) using a standardized case definition. A total of 5,522 cases were identified across the 11 countries during this period. Rates of reported infection varied, reaching 3/100,000 population in the northern European countries. Seasonal patterns of infection showed remarkable congruence between countries. The risk of infection was highest among the elderly, and rates were higher in males than in females in most countries. Skin lesions/wounds were the most common predisposing factor, reported in 25% of cases; 21% had no predisposing factors reported. Skin and soft tissue were the most common foci of infection, with 32% of patients having cellulitis and 8% necrotizing fasciitis. The overall 7-day case fatality rate was 19%; it was 44% among patients who developed streptococcal toxic shock syndrome. The findings from Strep-EURO confirm a high incidence of severe S. pyogenes disease in Europe. Furthermore, these results have identified targets for public health intervention, as well as raising awareness of severe S. pyogenes disease across Europe. PMID:18463210

A 67-year-old man came to our first aid for an acute pain in the left iliac fossa, in the flank, and in the ipsilateral thigh. Ultrasonography and computed tomography revealed a left abdominal wall, retroperitoneal, and iliopsoas abscess that also involved the ipsilateral obturator muscle. It proceeded with an exploratory laparotomy that showed a tumor of the descending colon adhered and perforated in the retroperitoneum with abscess of the iliopsoas muscle on the left-hand side, with presence of a fistula and liver metastases. A left hemicolectomy with drainage of the broad abscess was performed. Pathologic report findings determined adenocarcinoma of the resected colon. PMID:24744948

He had a puncture history of tongue by fishbone, which was immediately removed 3 weeks ago. The subsequent contrast-enhanced computed tomography scan of neck disclosed an abscess formation with a faint linear radiopaque material inside, consisting with remnant fishbone retention. The patient was treated conservatively with intravenous antibiotics, followed by an uneventful course during subsequent follow-up for more than 9 months until now. Tongue abscess is a rare but potentially life threatening clinical entity.

    The case of a patient with apparently primitive pituitary abscess is presented along with a review of the current literature on the subject. Pituitary abscess is rare and should be suspected in patients with hypopituitarism or a febrile chiasma syndrome as well as in the presence of acute or chronic relapsing aseptic meningitis. Diagnosis is based upon radiologic examination particularly tomography of the sella turcica and computerized axial tomography. With early surgical treatment the prognosis is favourable resulting at times in partial or total correction of pituitary function. Twenty-six patients were studied. In twelve of these patients no origin of the abscess was found. Pituitary tumor was found in eight patients and sphenoidal sinusitis in six patients. PMID:6261360

    Non typhoidal Salmonellae spp. causes clinical symptoms especially in neonates, infants, aged and immunocompromised patients. Hematogenous dissemination may occur in complicated cases whereas the formation of abscess is rare. A 61-year old woman presented to our hospital with pain and a mass in her left arm, without fever and leukocytosis. She was using methotrexate, corticosteroids and quinine for rheumatoid arthritis. She had a history of cervix cancer and was given radiotherapy and chemotherapy 3 years ago. Upon physical examination and magnetic resonance imaging, the mass was considered as an abscess and was surgically drained. Salmonella enterica spp. enterica was yielded in the culture of the drainage material. Ceftriaxon 2g/day was started intramuscularly and continued for 4 weeks. Salmonellosis is usually a self-limited disease, generally restricted to gastrointestinal tract and acquired following food poisoning. Management of Salmonella abscess requires a combination of antibiotherapy, surgical drainage and eradication of primary foci. PMID:24396582

    A 32-year-old woman presented with sepsis nine days after a transrectal incision and drainage of a recurrent supralevator abscess. The findings included a large mass arising from the pelvis containing multiple, leaking, and infected endometrial cysts. After a supracervical hysterectomy, bilateral salpingo-oophorectomy, sigmoid loop colostomy, appendectomy, and extensive irrigation and debridement, her condition improved with no recurrence at two-year follow-up. This case illustrates the varied presentations of endometriosis, the importance of identifying the source of a perirectal or perianal abscess, and that when a supralevator abscess develops from an intraabdominal process, the process must be addressed to prevent recurrence, fistulization, or other complications.

    A 56-year-old Caucasian lady presented with a short history of pleuritic chest pain on the background of a 2-month history of fever, chills, 10-kg weight loss and cough with brown sputum after a laparoscopic cholecystectomy. She had persistent eosinophilia and was diagnosed with a lung abscess as seen on chest x-ray. She did not respond to standard intravenous broad spectrum antibacterial medication and her chest CT scan showed a moderate pleural collection in continuity with the abscess. She also underwent bronchoscopy, the microscopy of the bronchial washings revealing eggs of the trematode Fasciola. The bacterial and fungal cultures of the washings were sterile. She had visited Turkey in the previous year but did not remember consuming any watercress or aquatic plants. She was successfully treated with two doses of the antiparasitic agent triclabendazole. Ectopic Fasciola can be a rare cause of a lung abscess. PMID:23595175

    Salmonella typhi is a true pathogen, which is capable of causing both intestinal and extraintestinal infections. Unusual presentations of Salmonella should always be kept in mind as this organism can cause disease in almost any organ of the body. S. typhi has been reported to cause the life-threatening infections such as meningitis, endocarditis, myocarditis, empyema, and hepatic abscess. Renal involvement by S. typhi is a relatively rare presentation. We report a case of renal abscess caused by S. typhi in an afebrile, 10-year-old child who did not have any clinical history of enteric fever. To our knowledge, this is the first reported case of isolation of S. typhi from the renal abscess, and interestingly this isolate was found to be resistant to quinolones. PMID:26417164

    We describe a complicated ruptured Streptococcus pyogenes tubo-ovarian abscess (TOA) and peritonitis in a 24-year-old woman, necessitating eventual hysterectomy and a prolonged intensive care unit (ICU) admission 3 years after successful tubal occlusion with Essure® (Conceptus, Inc., Mountain View, CA) microinsert devices. The patient is a 24-year-old gravida 3, para 2, aborta 1 (G3P2Ab1) who had a 1-day history of worsening right lower quadrant pain without associated fever or cervical motion tenderness. Patient's medical history was complicated by mitochondrial neurogastrointestinal encephalopathy (MNGIE). Upon her admission to the hospital, an exploratory laparoscopy was performed. Intraoperative findings revealed a ruptured right-sided TOA. S. pyogenes was isolated from the peritoneal fluid and cervicovaginal cultures. After the laparoscopy, the patient experienced initial improvement but abruptly worsened and on postoperative day 7 was returned to the operating room for a planned repeat exploration and total abdominal hysterectomy. Gross pathological examination of the uterus showed appropriate Essure insert placement. Based on this case, tubal occlusion by induced fibrosis may not be a sufficient obstacle in preventing ascending pelvic infections. PMID:21599428

    A brain abscess is uncommon but potentially lethal. Common predisposing risk factors include congenital cyanotic heart disease, immunocompromised status, and the presence of septic foci. We describe a left frontal brain abscess accompanied by fever, headache, and weight loss for a 3-month period. The presumptive source of the brain abscess involved a left peritonsillar abscess. To the best of our knowledge, one similar case was reported in the literature in 1929. The specific signs of peritonsillar abscess in our patient included trismus, decreased phonation, and a muffled voice. The peritonsillar abscess was not clinically diagnosed, but incidentally detected on lower axial sections of cranial magnetic resonance imaging. Fever and trismus improved after surgical drainage of the peritonsillar abscess. The cerebral abscess was conservatively treated with intravenous antibiotics. The patient developed hydrocephalus as a sequela to the involvement of the basal meninges. PMID:23127268

    Abstract Pyogenic sacroiliitis is exceptional in very young children. Diagnosis is difficult because clinical examination is misleading. FABER test is rarely helpful in very young children. Inflammatory syndrome is frequent. Bone scintigraphy and MRI are very sensitive for the diagnosis. Joint fluid aspiration and blood cultures are useful to identify the pathogen. Appropriate antibiotic therapy provides rapid regression of symptoms and healing. We report the case of pyogenic sacroiliitis in a 13-month-old child. Clinical, biological, and imaging data of this case were reviewed and reported retrospectively. A 13-month-old girl consulted for decreased weight bearing without fever or trauma. Clinical examination was not helpful. There was an inflammatory syndrome. Bone scintigraphy found a sacroiliitis, confirmed on MRI. Aspiration of the sacroiliac joint was performed. Empiric intravenous biantibiotic therapy was started. Patient rapidly recovered full weight bearing. On the 5th day, clinical examination and biological analysis returned to normal. Intravenous antibiotic therapy was switched for oral. One month later, clinical examination and biological analysis were normal and antibiotic therapy was stopped. Hematogenous osteoarticular infections are common in children but pyogenic sacroiliitis is rare and mainly affects older children. Diagnosis can be difficult because clinical examination is poor. Moreover, limping and decreased weight bearing are very common reasons for consultation. This may delay the diagnosis or refer misdiagnosis. Bone scintigraphy is useful to locate a bone or joint disease responsible for limping. In this observation, bone scintigraphy located the infection at the sacroiliac joint. Given the young age, MRI was performed to confirm the diagnosis. Despite the very young age of the patient, symptoms rapidly disappeared with appropriate antibiotic therapy. We report the case of pyogenic sacroiliitis in a 13-month-old child. It reminds the risk

    Parotid abscess is an uncommon condition in infants. It is frequently associated with prematurity, prolonged gavage feeding, and dehydration. Mumps is a viral disease caused by paramyxovirus. It frequently involves the parotid gland and is only rarely found in the pancreas, testis, or brain. The authors describe a rare case of a 10-month-old infant with mumps who developed the classical manifestations of unilateral acute parotitis progressing to formation of a parotid abscess that responded to 2 rounds of surgical drainage and antibiotic therapy.

    Prostatic abscess is a rare disease. In the light of two cases, the authors discuss the diagnostic and therapeutic aspects of this disease. Two patients, aged 17 and 55 years, presented nonspecific clinical features. Medical imaging (US, CT) established the diagnosis by showing a loculated cystic prostatic mass. Treatment consisted of transurethral drainage and antibiotics with a favourable course in both cases. Prostatic abscess is a rare disease for which the diagnosis has been facilitated by progress in medical imaging. The treatment of choice remains transurethral endoscopic drainage. PMID:10857153

    Staphylococcus aureus is a versatile bacterial pathogen that produces T cell-activating toxins known as superantigens (SAgs). Although excessive immune activation by SAgs can induce a dysregulated cytokine storm as a component of what is known as toxic shock syndrome (TSS), the contribution of SAgs to the staphylococcal infection process is not well defined. Here, we evaluated the role of the bacterial superantigen staphylococcal enterotoxin A (SEA) in a bacteremia model using humanized transgenic mice expressing SAg-responsive HLA-DR4 molecules. Infection with S. aureus Newman induced SEA-dependent Vβ skewing of T cells and enhanced bacterial survival in the liver compared with infection by sea knockout strain. SEA-induced gamma interferon, interleukin-12, and chemokine responses resulted in increased infiltration of CD11b(+) Ly6G(+) neutrophils into the liver, promoting the formation of abscesses that contained large numbers of viable staphylococci. Hepatic abscesses occurred significantly more frequently in S. aureus Newman-infected livers than in livers infected with the Newman sea knockout strain, promoting the survival of S. aureus in vivo. This represents a novel mechanism during infection whereby S. aureus utilizes SAgs to form a specialized niche and manipulate the immune system. PMID:24914221

    Patient: Male, 73 Final Diagnosis: Salmonella typhimurium abscess of the chest wall Symptoms: — Medication: Ciprofloxacin Clinical Procedure:— Specialty: Infectious Diseases Objective: Unusual clinical course Background: Non-typhoid Salmonella extra-intestinal infections usually develop in infants and in adult patients with pre-existing predisposing conditions. Blood stream infections and urinary tract infections are the most common clinical presentations, but other sites of infection may be involved as well. Case Report: We describe a case of invasive salmonellosis caused by Salmonella typhimurium involving the chest wall in a 73-year-old man. The patient had suffered from gastroenteritis followed by left basal pneumonia with pleural effusion 7 weeks before. The CT scan of the chest wall showed a pericostal abscess with shirt-stud morphology near the left last cartilaginous arch. The abscess was surgically drained and patient was cured after a 40-day ciprofloxacin treatment. Conclusions: A review of the literature on extra-intestinal non-typhoid salmonellosis shows that pleuropulmonary and soft-tissue infections are uncommon. We argue that non-typhoid Salmonella might be considered as a possible cause of chest wall abscess in individuals with recent history of gastroenteritis complicated by pneumonia and pleural effusion.

    A study of 12 patients with giant horseshoe abscess of the abdominal and pelvic cavities seen at the Surgical Services of the University of Cincinnati Medical Center has emphasized the complexity and bizarre nature of these lesions. These infections represented a huge abscess or series of communicating abscesses extending from one subphrenic space along the corresponding paracolic gutter into the pelvis, up and along the opposite paracolic space, and into the other subphrenic space. Since these lesions occurred infrequently, they were often not recognized until they had become far advanced and had produced profound effects on the patients. The diagnosis was difficult and obscured by various factors including the postoperative state after laparotomy for complex diseases or serious injuries of the biliary tract, the genitourinary tract, or the alimentary tract. An important etiologic component of the formation of these giant abscesses was the continuing escape and collection of large volumes of fluid resulting from lesions of the biliary tract, postoperative hemorrhage, or an unrecognized large perforated peptic ulcer. Nine patients were treated successfully and 3 died. The many diagnostic and therapeutic problems presented by the patients with this interesting and complex lesion have emphasized the importance of earlier and more accurate diagnosis, early and adequate surgical drainage, intelligently applied antibiotic therapy and appropriate supportive treatment. Failure to recognize and drain effectively each of the component sections of this lesion led to continuing sepsis with prolonged morbidity, progressive debility, and death. Images Fig. 1. Fig. 2.

    A superior subperiosteal orbital abscess (SSPOA) is a collection of purulent material between the periorbit and the superior bony orbital wall, and is typically a complication of frontal sinusitis. SSPOA is characteristically managed by classic external surgical drainage. The aim of our study was to assess the role of surgical intervention in SSPOA. A retrospective medical chart review of patients diagnosed with SSPOA secondary to rhinosinusitis between the year 2005 and 2013 was conducted. Collected data included age, gender, co-morbidity, clinical presentation, prior antibiotic management, CT scans, surgical approach, outcome and complications. Six patients were included in our study, three males and three females with a mean age of 22.8 (range 9-58). Two patients were treated with amoxicillin clavulanic acid for 3 days prior to admission. Only the youngest patient with the smallest abscess responded successfully to conservative treatment, while the rest were managed surgically: three patients were treated successfully by the endonasal endoscopic approach and two patients were treated by utilizing the combined endonasal endoscopic and external approach. In patients who underwent the combined approach, the abscess was located in a more antero-lateral position than those treated endonasal endoscopically only. The location of a SSPOA dictates the surgical approach. The most antero-lateral SSPOAs should be drained by the combined approach, while more posterior abscesses should be approached endoscopically. Furthermore, a small SSPOA is first to be reported to resolve with conservative treatment. Level 4 (case series). PMID:25700832

    A case of multiple intracranial abscesses in an immune-competent young girl is reported. She had chicken pox. Two weeks later, she presented with multiple intracranial abscesses. No significant cardiac abnormality was detected on transthoracic echocardiogram (TTE). The condition was treated medically. However, one of the abscesses adjacent to the CSF pathways enlarged on treatment and caused obstructive hydrocephalus that required stereotactic aspiration. Gram stain showed gram positive cocci in chain. Pus was sterile on culture. She was treated with broad spectrum IV antibiotics based on Gram staining report for 6 weeks followed by another 8 weeks of oral antibiotics. She made good recovery and had been leading a normal life. The abscess capsules took 30 months to resolve completely on MRI. A repeat TTE done in the follow up showed enlarged right heart chambers with a suggestion of a venosus ASD. A trans-esophageal echocardiogram (TEE) confirmed the presence of sinus venosus ASD from the SVC side with mainly left to right shunt. There was also partial anomalous drainage of the pulmonary veins. The patient underwent correction of the defect and has been doing well. PMID:24551007

    A 2-year-old boy with underlying congenital cyanotic heart disease presented with seizures and fever and was found to have bilateral parietal cerebral abscesses. Drainage of the pus from the abscesses was done in stages; on the day of admission, four days after admission and 3 weeks after admission. Although the pus from the first drainage did not grow any organisms, the pus from the second drainage on the fourth day of admission yielded a mixed growth of Eikenella corrodens and Streptococcus milleri. Following the second drainage of pus, the child was noted to have mild weakness (grade 3/5) and increased tone in the left upper limb. Three weeks after admission, due to recurring fever, further neurological signs and findings of an enlarging right cerebral abscess on a repeat CT scan, a third drainage was carried out. However no growth was obtained from this specimen. This patient was managed both surgically and with appropriate antibiotics. Over the next four months, serial CT scans revealed gradual resolution of the abscesses with disappearance of the surrounding oedema. The child showed gradual recovery of his left sided weakness with resolution of tone and reflexes to normal. PMID:16190107

    Intra-abdominal abscess is seldom adequately treated by systemic antibiotics alone and often requires surgical or computed tomography-guided drainage for resolution. Abscess penetration of six currently used antibiotics was examined in a murine intra-abdominal abscess model. Ampicillin/sulbactam, cefmetazole, clindamycin, and trospectomycin penetrated intra-abdominal abscesses to a greater degree than cefoxitin and ceftriaxone. Abscess pus antibiotic levels were not significantly higher after multiple doses than after a single dose. Pus antibiotic levels below the MIC90 for Bacteroides and E. coli within intra-abdominal abscess were observed for most antibiotics with the doses used in this study. Selection of antibiotics with a greater ability to penetrate abscess may be important in optimally treating patients with abdominal infection. PMID:7762902

    The clinical information and imaging data from 27 patients with hematogenous pyogenic vertebral osteomyelitis were reviewed. All patients had roentgenographic and magnetic resonance imaging examinations. Seventeen patients had computed tomograms; 17 had technetium Tc 99m medronate bone scans; and seven had gallium citrate Ga 67 scans. Magnetic resonance imaging, when used as a part of the initial radiologic evaluation, detected abnormalities consistent with osteomyelitis in all 27 patients. Magnetic resonance imaging also demonstrated paravertebral and/or epidural extension of infection in 14 patients, including seven patients who had neurologic signs of lower-extremity weakness. Roentgenograms, computed tomograms, technetium bone scans, and gallium scans had findings suggestive of the diagnosis in 48%, 65%, 71%, and 86% of the patients, respectively. We recommend magnetic resonance imaging as an important and perhaps critical imaging modality for detection of pyogenic vertebral osteomyelitis.

    Pyogenic granuloma (PG) is a small, almost always solitary, sessile or pedunculated, raspberry-like vegetation of exuberant granulation tissue. Conservative treatment by techniques such as cryosurgery, laser surgery, and electrodesiccation are usually adequate, whereas excisional treatment can often result in noticeable scars. We attempted a different approach using an injection of absolute ethanol in five patients with recurrence due to inadequate cryosurgery. This therapy is less invasive than surgical excision and appears to be an alternative therapy for PG. PMID:15187331

    The Gram-positive bacterium Streptococcus pyogenes is a major human pathogen causing substantial morbidity and mortality in society. S. pyogenes has evolved numerous molecular mechanisms to avoid the various actions of the human immune system and has established means to modulate both adaptive and innate immune responses. S. pyogenes produces and secretes proteolytic enzymes, which have an important impact on the ability of the bacteria to survive in the human host. Prominent among these are two immunoglobulin-degrading enzymes: the newly discovered streptococcal cysteine proteinase, IdeS, and the classical cysteine proteinase of S. pyogenes, SpeB.

    Pyogenic granuloma is one of the diseases sometimes seen in otorhinolaryngology clinics. The clinical features of this disease are understood to be that the lesion is located in the oral cavity in the majority of cases that its causative agent is usually discovered and that it most likely grows as a malignant tumor. However, the entity of pathological diagnosis has not been established. Thirty-one cases of oral pyogenic granuloma, including 16 males and 15 females, are reported in this paper. The granuloma was located most frequently at the tongue, followed, in order, by the gingiva, buccal mucosa, hard palate, lip and oral floor. The period between the patient's first visit to our clinic and the onset of his/her complaint was variable. It was relatively shorter in those cases with the lesion at the gingiva or tongue as compared to other locations. The size of the lesion was smaller than 10 x 10 mm. We classified the pathological features into three patterns; granuloma type, hemangioma type, and intermediate type. Many cases of lesions located at the back of the tongue, buccal mucosa, or hard palate were of the hemangioma type, while many cases of lesions located at the top of the tongue, gingiva, or oral floor were of the granuloma type. We have the impression that pyogenic granuloma could be one of the purulent changes associated with benign oral tumors. PMID:1779270

    Summary Although they possess a well-characterized ability to porate the bacterial membrane, emerging research suggests that cationic antimicrobial peptides (CAPs) can influence pathogen behavior at levels that are sub-lethal. In this study, we investigated the interaction of polymyxin B and human neutrophil peptide (HNP-1) with the human pathogen Streptococcus pyogenes. At sub-lethal concentrations, these CAPs preferentially targeted the ExPortal, a unique microdomain of the S. pyogenes membrane, specialized for protein secretion and processing. A consequence of this interaction was the disruption of ExPortal organization and a redistribution of ExPortal components into the peripheral membrane. Redistribution was associated with inhibition of secretion of certain toxins, including the SpeB cysteine protease and the Streptolysin O (SLO) cytolysin, but not SIC, a protein that protects S. pyogenes from CAPs. These data suggest a novel function for CAPs in targeting the ExPortal and interfering with secretion of factors required for infection and survival. This mechanism may prove valuable for the design of new types of antimicrobial agents to combat the emergence of antibiotic-resistant pathogens. PMID:22780862

    Tuboovarian abscess is a well-recognized complication of acute salpingitis and has been reported in as many as one third of hospital admissions for acute salpingitis. The incidence of tuboovarian abscess is expected to increase as a result of the current epidemic of sexually transmitted diseases and their sequelae. Patients with tuboovarian abscess most commonly present with lower abdominal pain and an adnexal mass(es). Fever and leukocytosis may be absent. Ultrasound, computed tomographic scans, laparoscopy, or laparotomy may be necessary to confirm the diagnosis. Tuboovarian abscess may be unilateral or bilateral regardless of intrauterine contraceptive device usage. Tuboovarian abscess is polymicrobial with a preponderance of anaerobic organisms. An initial conservative antimicrobial approach to the management of the unruptured tuboovarian abscess is appropriate if the antimicrobial agents used can penetrate abscesses, remain active within the abscess environment, and are active against the major pathogens in tuboovarian abscess, including the resistant gram-negative anaerobes such as Bacteroides fragilis and Bacteroides bivius. However, if the patient does not begin to show a response within a reasonable amount of time, about 48 to 72 hours, surgical intervention should be undertaken. Suspicion of rupture should remain an indication for immediate operation. Once operation is undertaken, a conservative approach with unilateral adnexectomy for one-side tuboovarian abscess is appropriate if future fertility or hormone production is desired.

    Trueperella pyogenes and Clostridium perfringens are two kinds of conditional pathogens frequently associated with wound infections and succeeding lethal complications in various economic livestock. Pyolysin (PLO) and phospholipase C (PLC) are the key virulence factors of these two pathogens, respectively. In our study, a chimeric protein called rPC-PD4, which is composed of the binding regions of PLO and PLC, was synthesized. The toxicity of rPC-PD4 was evaluated. Results revealed that rPC-PD4 is a safe chimeric molecule that can be used to develop vaccines. Immunizing BALB/c mice with rPC-PD4 induced high titers of serum antibodies that could efficiently neutralize the hemolytic activity of recombinant PLO and PLC. After the challenge with T. pyogenes or C. perfringens was performed through the intraperitoneal route, we observed that rPC-PD4 immunization could provide partial immunoprotection and reduce lung, intestine, and liver tissue damage to mice. This work demonstrated the efficacy of the rationally designed rPC-PD4 chimeric protein as a potential vaccine candidate against C. perfringens and T. pyogenes. PMID:27473983

    Pasteurella multocida is classically responsible for local soft tissue infections secondary to dog bites or cat scratches. It can be responsible for meningitis in infants and elderly persons. We report the case history of a 5-year-old male child admitted to our pediatric unit for meningitis. Cerebrospinal fluid analysis revealed an infection with P. multocida. The suspected mode of contamination was either from the saliva of a pet dog or through an unnoticed skull fracture sustained after an accident 1 year prior to the occurrence of meningitis. In spite of the neurologic complication (cerebral abscess), the progression was favorable after drainage of the abscess, 5 weeks of parenteral treatment, and 3 weeks of oral antibiotic therapy. Meningitis due to Pasteurella sp. is rare and can lead to neurologic complications. The notion of bites or scratches can be absent and the mode of contamination is sometimes difficult to unveil.

    Controversy regarding the use of anticoagulants, the evacuation of the sinus, or the use of medical treatment alone surrounds the treatment of lateral sinus thrombosis. Treatment of an epidural abscess associated with coalescent mastoiditis is much less controversial-drainage is usually recommended. The differing treatments of these complications mandate accurate diagnosis. The advent of more sophisticated radiological studies has facilitated diagnosis of these complications; however, tests are not infallible. We present three cases in which preoperative imaging demonstrates an epidural abscess mimicking lateral sinus thrombosis by compression of the vessel. A false-positive computed tomography (CT) or magnetic resonance imaging (MRI) study may lead to the wrong diagnosis and, consequently, improper treatment. In light of this possibility, we recommend surgical exploration in all such cases. ImagesFigure 1Figure 2Figure 3Figure 4 PMID:17171148

    Background: Nocardia infection of the central nervous system leading to brain abscess is a rare condition but has a high mortality rate. Among the species of Nocardia, only three cases of brain abscess due to Nocardia asiatica infection have been reported. Case Description: A 65-year-old man with a history of autoimmune hemolytic anemia treated with prednisolone presented to our hospital because of occipital headache. Brain magnetic resonance imaging showed bilateral occipital lesions. The patient underwent craniotomy and resection of the left occipital lobe lesion. N. asiatica was identified by 16S rRNA sequencing of the resected specimen. Treatment with trimethoprim/sulfamethoxazole led to a complete resolution of the brain lesion. Conclusion: Because of the different antimicrobial sensitivity patterns among Nocardia species, both appropriate subtyping and susceptibility testing of uncommon species such as N. asiatica are required for the successful treatment of nocardial infections.

    Descending necrotizing mediastinitis secondary to a nontraumatic retropharyngeal abscess is very rare. This form of mediastinitis in the era of potent antibiotics often ends up with lethal outcome. It usually occurs in immunocompromised patients and requires intensive multidisciplinary treatment approach. We report a case of nontraumatic retropharyngeal abscess complicated by descending necrotizing mediastinitis in a 70-year-old man with insulin dependent diabetes mellitus. The patient was admitted to our hospital after clinical and radiological diagnosis of retropharyngeal abscess. During treatment for retropharyngeal abscess with antibiotic therapy and transoral incision, the patient showed mild clinical improvement but his condition suddenly aggravated on day 4 of hospital stay. He had high fever, chest pain with tachypnea, tachycardia, hypotension, and showed signs of occasional disorientation. Emergency computed tomography (CT) scan of the neck and thorax showed inflammation in the retropharyngeal space, as well as thickening of the upper posterior mediastinum fascia with the presence of air. Emergency surgery including cervicotomy and drainage of the retropharyngeal space and posterior mediastinum was performed. The patient promptly recovered with improvement of the clinical status and laboratory findings. After 16 days of treatment he was discharged from the hospital in good condition. Descending necrotizing mediastinitis can be a serious and life threatening complication of deep neck infection if the diagnosis is not quickly established. Besides inevitable application of antimicrobial drugs, good drainage of the mediastinum is necessary. We believe that transcervical approach can achieve high-quality drainage of the upper mediastinum, especially if it is done timely as in this case. Its efficacy can be verified by intensive monitoring of the patient clinical condition, by CT scan of the thorax, and by laboratory tests. In the case of inefficacy of this type

    As the breadth of bacterial diversity in the oral cavity has been deciphered by molecular studies, several newly identified species/phylotypes have emerged as potential pathogens. We hypothesized that many of these species/phylotypes could also be involved with the etiology of endodontic abscesses. Abscess aspirates from 42 persons were analyzed for the presence of 81 species/phylotypes by means of a reverse-capture checkerboard hybridization assay. Associations between the most frequently detected taxa were calculated. The most prevalent taxa were Fusobacterium nucleatum, Parvimonas micra, and Porphyromonas endodontalis. Other frequently found taxa included Olsenella uli, streptococci, Eikenella corrodens, some as-yet-uncultivated phylotypes (Bacteroidetes clone X083 and Synergistes clone BA121), and newly named species (Prevotella baroniae and Dialister invisus). Several positive bacterial associations were disclosed. Findings not only strengthen the association of many cultivable species with abscesses, but also include some newly named species and uncultivated phylotypes in the set of candidate pathogens associated with this disease.

    We report a case of brain abscess caused by a penetrating head injury that occurred 9 years earlier. A 14-year-old girl presenting with fever, headache, and stiff neck was admitted to our hospital. She was diagnosed with aseptic meningitis and treated conservatively. Seven days after admission she became stuporous and showed left hemiparesis. Computed tomography (CT) revealed two ring-enhancing masses with perifocal edema in the right frontal lobe. We diagnosed brain abscess and performed right fronto-temporal decompressive craniectomy and stereotactic aspiration, followed by systemic antibiotic therapy. Post-surgery bone window CT revealed a well-defined, low-density foreign body passing from the left orbita to the right frontal lobe through the ethmoid sinus. We learned that the patient had been struck with a plastic chopstick in the left medial eyelid at the age of 5 years. No particular symptoms developed during the following 9 years. After the cerebral edema had diminished over the next 10 days, a second surgery was performed to remove the residual chopstick, repair the fistula at the base of the skull, and perform cranioplasty. The patient was discharged with only slight hyposmia after a 4-week course of antibiotics. This case showed that it is necessary to remove a residual foreign body and to close the dural fistula if there is a possibility of recurrent central nervous system infection. When a child presents with brain abscess, previous penetrating head injury should be considered. PMID:17491344

    Background: Nocardial brain abscesses are a rare central nervous system infection with high morbidity and mortality. Infection is acquired through inhalation or direct innoculation and then spreads hematogenously. They are usually associated with immunocompromised patients but may appear in otherwise healthy individuals. Treatment is based on surgical aspiration and antibiotics for several months. Case Description: We present four cases of nocardial brain abscesses treated at our institution and review the literature regarding these lesions. Ages ranged from 22 to 71 years. One patient was a healthy individual without any predisposing condition. Patients were treated with surgical evacuation and long term parenteral antibiotics. Two patients made a full recovery; one patient died and one recovered with significant morbidity. In one case malignancy was suspected, probably delaying diagnosis. Conclusions: Nocardial brain abscesses are a rare condition that needs to be considered in the differential diagnosis of brain lesions. They are not necessarily associated with predisposing factors such as immunosupresion. Treatment must be started as soon as possible with surgical evacuation and long term parenteral antibiotics in order to avoid significant morbidity. PMID:23050202

    A 20-month-old boy presented with 1-year history of persistent fever, cough, and progressive abdominal distention. Abdominal ultrasonography showed hepatomegaly and multiple calcifications in the liver and spleen. Thoracic computed tomography showed multiple mediastinal lymph nodes and consolidation in both lungs. Additionally, there was a 2-cm thick retroperitoneal soft tissue mass destroying the T7-8 and L1-L2 vertebral bodies. The patient was preliminarily diagnosed with miliary tuberculosis (TB) and Pott's disease, and began administering anti-TB treatment consisting of isoniazid, rifampin, ethambutol, and pyrazinamide. Acid-resistant bacilli analysis and mycobacterial culture of the biopsy specimen of Pott's abscess were positive. Mycobacterial culture and PCR of gastric aspirate were also positive. The patient's condition progressively improved with anti-TB treatment and he received 12 months of antiTB therapy. At the end of the treatment all of the patient's symptoms were relieved and he was well except for kyphosis. Miliary TB complicated by Pott's abscess is a very rare presentation of childhood TB. The presented case shows that when Pott's abscess is diagnosed and surgically corrected without delay, patients can recover without squeal. PMID:25983412

    Antiresorptive drugs have been widely used to treat patients with hypercalcemia caused by malignancy, bone metastasis, multiple myeloma, and osteoporosis. However, it is well known that antiresorptive drugs can cause osteonecrosis of the jaw (ONJ). Herein, we report a rare case of nasal septal abscess caused by medication related osteonecrosis of the jaw (MRONJ) in a breast cancer patient. A 69-year-old woman was referred to our clinic for evaluation of nasal obstruction. Physical examination revealed a cherry-like swelling of the nasal mucosa emanating from the septum that obstructed both nasal cavities and a fistulous tract showing pus discharge after extraction of the bilateral maxillary central incisors (MCI) and the right maxillary lateral incisor (MLI). Computed tomography and panoramic radiography revealed extensive osteonecrosis of the maxilla and swelling of the nasal mucosa. The clinical diagnosis was nasal septal abscess caused by osteonecrosis of the maxilla. Surgical procedure was undertaken for this case. An indwelling drain was placed in the oral cavity, and sequestrectomy was performed with incision and drainage of the anterior portion of left nasal septum. The patient was doing well at the 7-month follow-up. The patient had a medical history of breast cancer with bone, lung, liver metastases, and had received intravenous bisphosphonate, which is one of the antiresorptive medicines, over the past 4 years. We suspect that this history played an important role in MRONJ induced nasal septal abscess. PMID:26775849

    Luc abscess is an uncommon suppurative complication of otitis media. Unfamiliarity of this complication leads to delayed diagnosis and treatment. This abscess is usually benign. Infection in the middle ear spreads via anatomic preexisting pathways, and this process results with subperiosteal pus collection. Conservative treatment with drainage under empirical wide spectrum antibiotic is efficient.

    Trueperella (T.) pyogenes is an opportunistic pathogen that causes suppurative diseases in domestic animals. In this work, the properties, pathogenesis and phenotypic diversity of T. pyogenes isolates from bovine mastitis were studied. Both pyolysin (plo) and collagen-binding protein (cbp) virulence factor genes were detected by PCR in all T. pyogenes isolates (n = 50). Using the tissue culture plate method, 90% of T. pyogenes isolates were able to form biofilms. The minimum inhibitory concentrations (MICs) of 13 antimicrobials against T. pyogenes isolates were determined. High susceptibility was observed to rifampin (96%), ampicillin (94%), ciprofloxacin (94%), and penicillin (92%), while low susceptibility was found to trimethoprim-sulphamethoxazole (10%) and bacitracin (2%). The intracellular assay revealed that T. pyogenes isolates had different cytopathogenic effects on cells. The high percentage (28.6%) of T. pyogenes isolates suggests that this bacterium is an important contributor to mastitis. Moreover, the high occurrence of multidrug resistance, biofilm production, intracellular survival, and the temporal dynamics of T. pyogenes interactions are key factors for a better understanding of how immunity acts on infections with these bacteria and how they evade immune surveillance, thus highlighting the need for the prudent use of antimicrobial agents in veterinary medicine.

    Pyogenic granuloma (PG) is a benign inflammatory lesion, nonneoplastic in nature, which occurs in the oral cavity and skin. This lesion arises in response to various stimuli such as low-grade local irritations, traumatic injury, or hormonal factors. Recently, in some cases, the occurrence of recurrent PGs in skin associated with vascular lesions, such as port-wine stains, has been described. It has been postulated that this association is promoted by arteriovenous anastomoses in the vascular lesions, leading to the development of PG. The authors discuss 2 cases of recurrent PG in patients with a port-wine stain, and the treatment options adopted. PMID:22134277

Oral PGs have never been described previously in hemophilia. We describe 2 pediatric patients with hemophilia A, who developed PGs with inadequate factor therapy for bleeding. PG pathophysiology suggests an association with hemophilia given chronic vascular damage and low-grade inflammation at sites of bleeding in hemophilia patients. Knowledge about the occurrence of PGs in hemophilia patients is essential for prompt diagnosis and early institution of factor therapy, which in turn allows more rapid cessation of bleeding and lesion involution.

    Intracranial abscesses are serious complications of chronic suppurative otitis media (COM). This study included 32 patients presenting with intracranial abscesses from 780 patients hospitalized for treatment of COM. The 32 patients had 59 intracranial complications. Perisinus abscess (13 of 32) was the most common intracranial abscess, followed by temporal lobe abscess (8 of 32), epidural abscess (7 of 32), cerebellar abscess (6 of 32) and subdural empyema (2 of 32). Headache (93%), fever (87%) and altered mental status (62%) were the most common presenting symptoms and signs, along with symptoms of COM. All patients were treated with intravenous antibiotics and canal wall down mastoidectomy. Cholesteatoma with granulation tissue and bony defects at the sinus plate and/or dural plate were seen in most of the patients. Gram negative bacilli and anaerobes were the most common organisms cultured from the abscesses. Three patients had neurological sequels. One patient died. The early diagnosis of these complications requires a high index of suspicion and imaging studies. A multidisciplinary and coordinated approach is important for the management of these patients.

    That a female patient with abdominal pain is often considered to have pelvic inflammatory disease until proven otherwise is ubiquitous in the medical literature. This view is dangerous and should be challenged because it has resulted in episodes of ruptured appendix, death from ruptured ectopic pregnancies, and serious morbidity from delayed diagnoses of such entities as diverticulitis and endometriosis. Proper diagnostic steps should be taken for all patients with abdominal pain of unclear etiology. This article reviews the pathogenesis of tubo-ovarian abscesses so as to separate and clearly identify fact from fiction. Diagnostic steps and management guidelines are discussed. PMID:3537321

    Pyogenic cervical facet joint infections are rare and such infections from a dental origin are even less common. Of these few cases, none have described infection with Streptococcus intermedius as the pathogen. A 65-year-old orthopaedic surgeon complained of fevers, right-sided radiating neck pain, stiffness, swelling, erythema, and right upper extremity weakness one month after he had broken a crown over his right mandibular premolar, a continued source of pain. Imaging of the cervical spine showed a right C4-C5 facet inflammatory arthropathy and a small epidural abscess that was cultured and initially treated with intravenous antibiotics. The oral maxillofacial surgery team performed an extraction of the infected, symptomatic tooth. For continued right upper extremity weakness, the patient underwent C4-C5 laminoforaminotomy and irrigation and debridement of the right C4-C5 facet joint. After 6 weeks of intravenous antibiotics, the patient's infectious and inflammatory markers had normalized. By 4 months, he had regained full strength at his upper extremity and a painless and full range of motion of his cervical spine.Pyogenic cervical facet joint infection is very rare and potentially dangerous. A high clinical suspicion and appropriate imaging, including magnetic resonance imaging, are important for correct diagnosis. Prompt medical and surgical treatment may avert complications, and although the patient presented made a complete recovery, patients may be left with neurological compromise. PMID:27620549

    The sal lantibiotic locus plays an important role in the virulence of Streptococcus pyogenes. Our transcriptional analysis of the sal locus provides new information on the complex regulation of this operon. Transcription of the operon is regulated by a promoter upstream of the operon and by a second internal promoter upstream of the salKRZ genes. Here we identify the location of the internal promoter and provide information on how this promoter is autoregulated by proteins within the locus. We determined by primer extension that the salKR promoter is located within the salY gene and identified several regulatory regions important for expression. The higher activity of the promoter in a salKR deletion strain indicates a role in repression by the SalR response regulator. Further, this promoter had higher activity in a salA deletion strain, implicating corepression or a signaling role for the SalA peptide. Finally, we demonstrate that this promoter can be controlled by host factors. Analysis of transcriptional regulation of this locus provides a better understanding of the function of the sal locus in S. pyogenes pathogenesis. PMID:24244008

    2016-01-01

    The aim of this article is to present a rare case of a bilateral recurring pyogenic granuloma around dental implants supported by autogenic bone graft. A 55-year-old woman was treated with vertical bone augmentation and dental implants on both sides in the mandible. The patient was followed up for 2 years. Growing granuloma was observed 3 weeks after implants were loaded with splinted porcelain-fused-to-metal crowns. The granulomatous tissue was removed and samples were evaluated histologically and microbiologically with real-time polymerase chain reaction. The pathologic lesion recurred four times on one side and three times on the other side and was removed after each recurrence. Finally, the patient decided to have the implants removed due to the aggressive, permanent, and relapsing nature of the proliferative lesions associated with exposed implant threads. After implant removal, no hyperplasia was seen. Microbiologic contamination was excluded as a cause of this recurring granuloma, and it was presumed that the lesion could have been associated with an insufficient zone of attached gingiva around the implants and exposure of implant threads. However, the etiology of this pyogenic granuloma remains unknown. Due to the high recurrence rate of reactive hyperplastic lesions, a long-term follow-up is necessary. PMID:27333016

    Introduction: Pyogenic granuloma (PG) is one of the inflammatory hyperplasia seen in the oral cavity. It is a reactional response to minor trauma or chronic irritation and also might be related to hormonal changes. Rarely, PG occurs extragingivally.The most common treatment of PG is surgical excision but alternative approaches such as laser excision have also been proposed. Case report: Herein, we present a case of lip pyogenic granuloma in a 15-year-old male whom had been under orthodontic treatment. The lesion was first excised with diode laser as a conservative method, but the lesion had immediately recurred and was excised with surgical blade as the traditional method. No recurrence or scarring was observed in 6 months follow-up. Results and conclusion: Although the use of laser as modern medicine offers a new tool for treatment of oral lesions, scalpel (blade) surgical excision still seems to be the successful treatment of choice in minimizing the recurrence of lesion especially when exacerbating factors such as hormonal imbalances exist.

    Background The occurrence of pyogenic granuloma in association to dental implants is rare and only five cases have been reported in the literature. Material and Methods Patients charts were analyzed to select patients who had been diagnosed for pyogenic granuloma and its association with dental implants had been evaluated. The clinical status of the dental implants and the prosthesis had also been assessed. Results Clinical and histopathological diagnosis of pyogenic granuloma had been reached for soft mass growth in association with dental implants in 10 patients. Histological analysis of all samples was performed to obtain a firm diagnosis of finding against pyogenic granuloma lesions. Accumulation of dental plaque due to poor oral hygiene and improper design of the prosthesis had been related to the occurrence of pyogenic granuoloma. This lesion showed no predilection to specific surface type and had no significant association with marginal bone loss. Conclusions Pyogenic granuloma should be included in the differential diagnosis of soft mass growth around dental implants. Key words:Reactive lesion, soft mass, pyogenic granuloma, dental implant, titanium. PMID:26535087

    Pyogenic granuloma is a benign nodular lesion occurring most commonly on the gingiva of females during periods of elevated sex hormones such as puberty and pregnancy. Possible molecular mechanisms responsible for the appearance of pyogenic granuloma in this demographic have been suggested. Increased incidence of pyogenic granuloma in post menopausal women on hormone replacement therapy has not been reported. A 49-year-old woman with preexisting titanium implant placement in the left posterior mandible presented with complaint of food impaction and slight discomfort associated with the implant. Clinical examination revealed slight soft tissue erythema and edema, but no foreign body could be identified. Subsequently, a nodular gingival lesion associated with the implant developed and was treated by conservative surgical excision. Histologic characteristics of the lesion were consistent with pyogenic granuloma. The patient was informed of the diagnosis. No evidence of recurrence could be identified after 6 months. Like peripubertal and pregnant women, postmenopausal women treated with hormone replacement therapy may be at increased risk for pyogenic granuloma. Observational studies designed to establish an association between hormone replacement therapy and pyogenic granuloma have not been conducted. Dentists should be aware of putative pathophysiologic mechanisms for pyogenic granuloma formation and the possibility that hormone replacement may trigger these mechanisms. PMID:21409768

    Endoscopic tattooing with India ink is generally regarded as a safe procedure that enables ready identification of endoluminal cancer from the serosal surface. However, significant complications have been reported, including local inflammatory pseudotumor formation, peritonitis, rectus muscle abscess, small bowel infarction, and phlegmonous gastritis. Although the mechanism of complication is not completely understood, it may be related to the chemical compounds contained in the ink solution and enteric or extraenteric bacterial inoculation by injection needle or the ink itself. Authors encountered a case of a 60-year-old man with a resectable sigmoid colon cancer which was tattooed with India ink for subsequent localization in the intraoperative setting. During the laparoscopic operation, the proximal and distal margin of the lesion appeared edematous with bluish color. The distal resection margin was extended approximately 5 cm more than expected because of long extent of edematous mucosa. Histologic examination of the edematous tattooing area revealed an ink abscess spreading laterally above the muscularis propria. Although tattooing is widely used and relatively safe, the presented case indicates the risk of infection or inflammation by tattooing. PMID:25073671

    Methicillin-resistant Staphylococcus aureus (MRSA) is a rare cause of cerebral abscesses, however it is a relatively more common etiologic agent in post-neurosurgical abscesses and the main antibacterial therapy option is vancomycin. In this report, a case of brain abscess due to MRSA which did not respond neither to moxifloxacin + vancomycin nor vancomycin + rifampin combination therapies, and merely treated by linezolid + rifampin combination, has been presented. Fifty-one years old female patient who was operated 40 days ago for subarachnoid bleeding and aneurysm in middle cerebral artery bifurcation, was hospitalized due to purulent leakage from the operation area. She did not have fever and her physical examination, including the neurologic system, was normal. Computerized tomography revealed an approximately 1 cm lesion compatible with subdural empyema and cerebral abscess in the right frontoparietal area in supratentorial sections. The patient was operated for wound revision and moxifloxacin was initiated. Since the operation materials revealed MRSA growth, vancomycin (4 x 500 mg, IV) was added to the treatment. The isolate was identified by conventional methods, and antibiotic susceptibility test performed by disk diffusion method showed that it was susceptible to levofloxacin, linezolid, rifampin, vancomycin and teicoplanin. Since no clinical response was obtained in two weeks, moxifloxacin was switched to rifampin (300 mg 1 x 2). On the 10th day of vancomycin + rifampin therapy, radiological findings showed development of cerebritis and therefore vancomycin was changed with linezolid (2 x 600 mg, IV). The control CT of the patient revealed regression of the brain lesion and linezolid + rifampin treatment continued for six weeks. The patient did not develop any hematological, liver or renal toxicity during the therapy and the radiological findings regressed. No relapse were detected in the one year follow-up period. This case suggested that linezolid might

    AIM: To elucidate the clinical, radiological and laboratory profiles of renal abscess (RA) and perinephric abscess (PNA), along with related treatment and outcome. METHODS: Ninety-eight patients diagnosed with RA or PNA using the primary discharge diagnoses identified from the International Statistical Classification of Diseases and Related Health Problems Tenth Edition (ICD-10) codes (RA: N15.101, PNA: N15.102) between September 2004 and December 2014 in West China Hospital were selected. Medical records including patients’ characteristics, symptoms and signs, high-risk factors, radiological features, causative microorganisms and antibiotic-resistance profiles, treatment approaches, and clinical outcomes were collected and analyzed. RESULTS: The mean age of the patients was 46.49 years with a male to female ratio of 41:57. Lumbar pain (76.5%) and fever (53.1%) were the most common symptoms. Other symptoms and signs included chills (28.6%), anorexia and vomiting (25.5%), lethargy (10.2%), abdominal pain (11.2%), flank mass (12.2%), flank fistula (2.0%), gross hematuria (7.1%), frequency (14.3%), dysuria (9.2%), pyuria (5.1%) and weight loss (1.0%). Painful percussion of the costovertebral angle (87.8%) was the most common physical finding. The main predisposing factors were lithiasis (48.0%), diabetes mellitus (33.7%) followed by history of urological surgery (16.3%), urinary tract infections (14.3%), renal function impairment (13.3%), liver cirrhosis (2.0%), neurogenic bladder (1.0%), renal cyst (1.0%), hydronephrosis (1.0%), chronic hepatitis B (1.0%), post-discectomy (1.0%) and post-colectomy (1.0%). Ultrasound (US) and computed tomography were the most valuable diagnostic tools and US was recommended as the initial diagnostic imaging choice. Escherichia coli (51.4%), Staphylococcus aureus (10.0%) and Klebsiella pneumoniae (8.6%) were the main causative microorganisms.

    Despite good results of orthotopic liver transplantation in patients with fulminant hepatic failure the need still exists for an effective and safe artificial liver, able to temporarily take over the complex liver function so as to bridge the gap with transplantation or regeneration. Attempts to develop non-biological artificial livers have failed, mostly when controlled clinical trials were performed. In the last decade several different types of bioartificial livers have been devised, in which the biocomponent consists of freshly isolated porcine hepatocytes or a human hepatoblastoma cell line. The majority use semipermeable hollow fibers known from artificial kidney devices. The liver cells may lie either inside or outside the lumen of these fibers. In vitro analysis of liver function and animal experimental work showing that the bioartificial liver increases survival justify clinical application. Bioartificial livers are connected to patients extracorporeally by means of plasmapheresis circuit for periods of about 6 hours. In different trials about 40 patients with severe liver failure have been treated. No important adverse effects have not been reported in these phase I trials. Results of controlled studies are urgently needed. As long as no satisfactory immortalised human liver cell line with good function is available, porcine hepatocytes will remain the first choice, provided transmission of porcine pathogens to man is prevented.

    The hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber disease) is an inherited autosomal dominant disease with angiodysplasia of the skin, mucosa, parenchymal organs, and it can affect the central nervous system. In 40% of the cases neurological complications, most frequently intracerebral abscesses occur. In this study, the case history of a patient with central nervous system manifestation of hereditary hemorrhagic telangiectasia showing familiar aggregation of brain abscess will be presented. A young male patient was admitted to Neurological Department because of his first epileptic seizure and progressive right hemispheric symptoms. His examinations showed frontal abscess, which was surgically removed. The frequent nose-bleeding of the patient and recurrent brain abscess in his brother's history provided the possibility of hereditary hemorrhagic telangiectasia. The background of brain abscess were multiple pulmonary arteriovenous malformation, which were embolized by repeated angiography. Familiar brain abscess is very rare. However, in the case of brain abscess especially with familiarity diagnosis of the Rendu-Osler-Weber disease should be considered. PMID:11760648

    Background The incidence of prostatic abscess (PA) has markedly declined with the widespread use of antibiotics and the decreasing incidence of urethral gonococcal infections. Objectives To evaluate different treatment methods for prostatic abscess and to describe technical points that will improve the outcome of transurethral (TUR) drainage of prostatic abscess. Patients and Methods We performed a retrospective study of a series of 11 patients diagnosed with prostatic abscess, who were admitted and treated in Farwaniya Hospital, Kuwait, between February 2008 and November 2010. Drainage was indicated when antibiotic therapy did not cause clinical improvement and after prostatic abscess was confirmed by TRUS (Transrectal ultrasonography) and/or CT computed Tomographyscan. TUR drainage was indicated in 7 cases, ultrasound-guided transrectal drainage was performed in 2 cases, and ultrasound-guided perineal drainage was performed in 2 cases. Results All patients that underwent TUR-drainage had successful outcomes, without the need of secondary treatment or further surgery. Conclusions TUR drainage of a prostatic abscess increases the likelihood of a successful outcome and lowers the incidence of treatment failure or repeated surgery. Less invasive treatment, with perineal or transrectal aspiration, may be preferred as a primary treatment in relatively young patients with localized abscess cavities. PMID:23573466

    Background and objectives Acute apical abscesses are serious endodontic diseases resulting from pulpal infection with opportunistic oral microorganisms. The objective of this study was to identify and compare the oral microbiota in patients (N=18) exhibiting acute apical abscesses, originating from the demographic region in Portland, Oregon. The study hypothesis is that abscesses obtained from this demographic region may contain unique microorganisms not identified in specimens from other regions. Design Endodontic abscesses were sampled from patients at the Oregon Health & Science University (OHSU) School of Dentistry. DNA from abscess specimens was subjected to polymerase chain reaction amplification using 16S rRNA gene-specific primers and Cy3-dCTP labeling. Labeled DNA was then applied to microbial microarrays (280 species) generated by the Human Oral Microbial Identification Microarray Laboratory (Forsyth Institute, Cambridge, MA). Results The most prevalent microorganisms, found across multiple abscess specimens, include Fusobacterium nucleatum, Parvimonas micra, Megasphaera species clone CS025, Prevotella multisaccharivorax, Atopobium rimae, and Porphyromonas endodontalis. The most abundant microorganisms, found in highest numbers within individual abscesses, include F. nucleatum, P. micra, Streptococcus Cluster III, Solobacterium moorei, Streptococcus constellatus, and Porphyromonas endodontalis. Strong bacterial associations were identified between Prevotella multisaccharivorax, Acidaminococcaceae species clone DM071, Megasphaera species clone CS025, Actinomyces species clone EP053, and Streptococcus cristatus (all with Spearman coefficients >0.9). Conclusions Cultivable and uncultivable bacterial species have been identified in endodontic abscesses obtained from the Portland, Oregon demographic region, and taxa identifications correlated well with other published studies, with the exception of Treponema and Streptococcus cristae, which were not commonly

    Pyogenic granuloma (PG) is a rare, benign, vascular, hyperplasic, soft tissue lesion caused by diverse factors, including traumatic injuries. This article presents a case involving the surgical removal of PG on the tongue of a 4-year-old boy who had difficulty with speech and eating because of the tongue lesion. The parents reported that the child had the habit of nibbling on and sucking his tongue. The lesion was excised and histopathological analysis confirmed the diagnosis of PG; however, because the child continued to nibble and suck on his tongue, the lesion recurred. A second surgery was performed with the same histopathological diagnosis. At a one-year follow-up, the child had ceased his tongue habits, and no recurrence was seen. PMID:23928434

    ABSTRACT The ability to hide in the animal kingdom is essential for survival; the same is true for bacteria. Streptococcus pyogenes is considered one of the more successful stealth bacteria in its production of a hyaluronic acid capsule that is chemically identical to the hyaluronic acid lining human joints. It has also acquired the capacity to enter eukaryotic cells to avoid the onslaught of the host’s immune defenses, as well as drugs. From this intracellular vantage point, it may remain dormant from days to weeks, only to cause disease again at a later time, perhaps causing a relapse in a drug-treated patient. We now learn that it is able to enter macrophages as well, enabling the Streptococcus to use this “Trojan horse” approach to be transported to distant sites in the body. PMID:27190219

It has also acquired the capacity to enter eukaryotic cells to avoid the onslaught of the host's immune defenses, as well as drugs. From this intracellular vantage point, it may remain dormant from days to weeks, only to cause disease again at a later time, perhaps causing a relapse in a drug-treated patient. We now learn that it is able to enter macrophages as well, enabling the Streptococcus to use this "Trojan horse" approach to be transported to distant sites in the body. PMID:27190219

    2015-01-01

    Pyogenic granulomas (PGs) in the oral cavity present as an inflammatory hyperplasia usually caused by trauma, hormonal imbalance, chronic irritation, or as the response to a wide variety of drugs. PGs with atypical presentation and behavior may clinically mimic malignant tumors. Thus, histological examination is required to rule out cancer development. Lesions in the oral cavity have been described to be either an isolated entity or present in multiple forms and with multiple recurrences. Conservative surgical excision is the standard choice of treatment in almost every scenario. However, the severity of the lesions and the affected sites often challenge surgical treatment. In this report, we describe the clinical scenario of a recurrent PG, where surgical excision of the lesion was questioned. As an alternative, we describe a noninvasive approach with lesional steroid injections. PMID:26668570

    The palatal mass can pose a difficult diagnostic dilemma for the clinician. In differential diagnosis of the palatal mass, dental causes must be considered because they are so common. The palatal abscess typically represents the palatally directed drainage of an infection of pulpal or periodontal origin. The palatal abscess is often observed in the premolar-molar region and presents as a compressible mass or swelling usually lateral to the midline. This study reports the unusual case of a 5-year-old girl with a palatal abscess adjacent to the midline. PMID:19212536

    Background: Stroke is a common provisional diagnosis in patients presenting to the emergency department (ED) with unilateral neurological deficit. Cervical epidural abscess (CEA) may also present clinically with a unilateral neurological deficit. Objects: To highlight the inherent problems with diagnosing cervical epidural abscess and possible consequences of delay in diagnosis. Case Report: We would like to highlight two cases provisionally diagnosed as stroke. Both cases turned out to be cervical epidural abscesses. The delay in diagnosis and treatment led to suboptimal outcome in both cases. Summary: Cases with suspected stroke who deteriorate while under treatment or whose diagnosis is doubtful should have MRI whole spine in order to avoid potential complications. PMID:24551026

    Renal abscesses are rare in childhood. The diagnosis is often complicated by non-specific symptoms and the typical signs of urinary tract infections are frequently absent. The currently available imaging methods are necessary and helpful for a differentiated therapeutic approach; nevertheless, cases are continuously being found in which a renal abscess is only diagnosed intraoperatively. In most patients a combined intravenous therapy including an antibiotic which is effective against staphylococci is sufficient. The therapy is supported if necessary by percutaneous abscess drainage. Open revision or even nephrectomy is rarely required. PMID:25190305

    Three cases of multiple cerebral nocardial abscess are presented. All were cured by a combination of chemotherapy and surgery, a unique experience. Early detection, appropriate chemotherapy, absence of underlying immune malfunction, and surgically remediable disease are good prognostic indices in cerebral nocardiosis. If other adverse prognostic factors are absent, however, multiple abscess formation does not preclude the possibility of cure. Accurate localisation of nocardia cerebral abscesses by computerised axial tomography is a great help in management if multiple lesions are present. Images PMID:501368

    Immunity to common bacteria requires the generation of antibodies that promote opsonophagocytosis and neutralise toxins. Pooled human immunoglobulin is widely advocated as an adjunctive treatment for clinical Streptococcus pyogenes infection however, the protein targets of the reagent remain ill defined. Affinity purification of the anti-streptococcal antibodies present within pooled immunoglobulin resulted in the generation of an IgG preparation that promoted opsonophagocytic killing of S. pyogenes in vitro and provided passive immunity in vivo. Isolation of the streptococcal surface proteins recognised by pooled human immunoglobulin permitted identification and ranking of 94 protein antigens, ten of which were reproducibly identified across four contemporary invasive S. pyogenes serotypes (M1, M3, M12 and M89). The data provide novel insight into the action of pooled human immunoglobulin during invasive S. pyogenes infection, and demonstrate a potential route to enhance the efficacy of antibody based therapies.

    Aim: The aim of this study is to highlight the development of pyogenic granuloma and hemangioma after the placement of dental implants. Materials and Methods: A literature search was performed using MEDLINE, accessed via the National Library of Medicine PubMed Interface, for articles published between 2000 and 2014 in English, relating to the occurrence of pyogenic granuloma or hemangioma in relation to dental implants. Results: Our search identified only four case reports of pyogenic granuloma and hemangioma related to dental implants as reported in the English literature. Conclusion: Placement of dental implants can cause development of pyogenic granuloma and hemangioma, indicating that placement of dental implants requires well-trained specialists with perfect skills in dental implantology. Furthermore, the critical selection of the appropriate case is of paramount importance to avoid the occurrence of such complications. PMID:25992330

    Streptococcus pyogenes secretes many proteins that influence host-pathogen interactions. Despite their importance, relatively little is known about the regulation of these proteins. The rgg gene (also known as ropB) is required for the expression of streptococcal erythrogenic toxin B (SPE B), an extracellular cysteine protease that contributes to virulence. Proteomics was used to determine if rgg regulates the expression of additional exoproteins. Exponential- and stationary-phase culture supernatant proteins made by S. pyogenes NZ131 rgg and NZ131 speB were separated by two-dimensional electrophoresis. Differences were identified in supernatant proteins from both exponential- and stationary-phase cultures, although considerably more differences were detected among stationary-phase supernatant proteins. Forty-two proteins were identified by peptide fingerprinting with matrix-assisted laser desorption mass spectrometry. Mitogenic factor, DNA entry nuclease (open reading frame [ORF 226]), and ORF 953, which has no known function, were more abundant in the culture supernatants of the rgg mutant compared to the speB mutant. ClpB, lysozyme, and autolysin were detected in the culture supernatant of the speB mutant but not the rgg mutant. To determine if Rgg affected protein expression at the transcriptional level, real-time (TaqMan) reverse transcription (RT)-PCR was used to quantitate Rgg-regulated transcripts from NZ131 wild-type and speB and rgg mutant strains. The results obtained with RT-PCR correlated with the proteomic data. We conclude that Rgg regulates the transcription of several genes expressed primarily during the stationary phase of growth.

    Infectious orbital complications after strabismus surgery are rare. Their incidence is estimated to be 1 case per 1,100 surgeries and include preseptal cellulitis, orbital cellulitis, subconjunctival and sub-Tenon's abscesses, myositis, and endophthalmitis. This report describes the case of an otherwise healthy 3-year-old boy who underwent bilateral medial rectus recession and disinsertion of the inferior obliques. A few days after surgery, the patient presented with bilateral periorbital edema and inferotemporal chemosis. A series of CT scans with contrast revealed inferotemporal orbital collections OU. The patient immediately underwent transconjunctival drainage of fibrinous and seropurulent collections in the sub-Tenon's space and experienced rapid improvement a few days later. The patient is reported to be in stable condition in a follow-up examination performed more than a year after the reported events. PMID:24896771

    The extracranial internal carotid artery aneurysm (EICAA) is an uncommon arterial lesion. Patients typically present with neurologic symptoms resulting from impaired cerebral perfusion and compression symptoms of cranial nerves. Often EICAA presents as a pulsatile neck mass, which is otherwise asymptomatic. We present a case of an 84-year-old female, who was initially referred to the Emergency Department for Otolaryngology with suspected peritonsillar abscess. The patient had a history of recent upper airway infection and cardiovascular comorbidities, including hypertension and ischaemic stroke complicated by extensive neurologic deficits. Physical examination revealed a compact, nonpulsatile mass in the lateral parapharyngeal space and local erythema of the mucosa. Duplex Doppler Ultrasonography and Computed Tomography revealed an atherosclerotic aneurysm of the right internal carotid artery, measuring 63 × 55 × 88 mm, stretching from the skull base to the angle of the mandible.

    Salmonella vertebral osteomyelitis is an uncommon complication of Salmonella infection. We report a case of a 57-year-old transgender male who presented with lower back pain for a period of one month following a fall. Physical examination only revealed tenderness over the lower back with no neurological deficits. MRI of the thoracic and lumbar spine revealed a spondylodiscitis at T10-T11 and T12-L1 and right posterior epidural collection at the T9-T10 level. He underwent decompression laminectomy with segmental instrumentation and fusion of T8 to L3 vertebrae. Intraoperatively, he was found to have acute-on-chronic osteomyelitis in T10 and T11, epidural abscess, and discitis in T12-L1. Tissue and wound culture grew Salmonella Typhi and with antibiotics susceptibility guidance he was treated with intravenous ceftriaxone for a period of six weeks. He recovered well with no neurological deficits. PMID:27034871

    Abstract Brain nocardiosis is a serious opportunistic infection with high mortality. It exists more common in the immunocompromised hosts than the immunocompetent patients. Trimethoprim-sulfamethoxazole (TMP-SMZ) has been mostly considered as the choice of the medical treatment. Linezolid is also newly found to be effective to avoid the invasive surgery. The authors reported a case of patient with multifoci nocardial brain abscesses who failed with the combination of linezolid and TMP-SMZ alone but recovered with the surgery intervention and sequential antibiotics for 2 years. The patient lived a high quality life without recurrence and complications during the 30 months follow-up. Through the literature review, we recommend earlier stereotactic aspiration for diagnosis, combination with surgery intervention and prolonged anti-infection therapy would improve the prognosis.

    Burkholderia, an aerobic gram-negative rod, is the causative organism behind melioidosis and is a common soil and water organism found predominantly in South-East Asia. We report the case of a 68 year-old man returning from an extended trip to the Philippines, with splenic hypodense lesions on abdominal computer tomography scan, later confirmed to be culture-positive for Burkholderia pseudomallei. The patient was treated with a course of intravenous ceftazidime followed by eradication therapy with oral doxycycline and trimethoprim-sulfamethoxazole. He recovered with complete resolution of symptoms at follow up. In a returning traveler from an endemic area, melioidosis should be considered as part of the differential for any febrile illness with abscesses. PMID:25874071

    Chicken pox is the most frequent exantematic illness; usually its course is self-limited and benign. Several bacterial complications are described due to the disruption of the skin as a defensive barrier because of the characteristics of the injuries and the associated inmunodepression. Psoas abscess is a rare illness and it's difficult to diagnose, with a general unspecified clinical presentation. We present the case of a 5-year-old girl, on her fifth day of chicken pox, who consults about a febrile convulsion, from which she recovers without any neurological symptoms, referring to functional impotence of her inferior left limb and pain in the lumbar and gluteal zone, which irradiates to the homolateral hip, making deambulation impossible. The definitive diagnosis was made with a CAT at hospital admission. The germ isolated was community-acquired methricillin-resistant Staphilococcus aureus. Treatment consisted in surgical drainage and endovenous antibiotics. PMID:20544129

    Background There are limited data describing the clinical characteristics of pyogenic spondylitis caused by Gram-negative bacteria (GNB). The aim of this study was to investigate the predisposing factors and clinical characteristics of pyogenic spondylitis caused by GNB compared to Gram-positive cocci (GPC). Methods We performed a retrospective review of medical records from patients with culture-confirmed pyogenic spondylitis at four tertiary teaching hospitals over an 8-year period. Results A total of 344 patients with culture-confirmed pyogenic spondylitis were evaluated. There were 62 patients (18.0%) with pyogenic spondylitis caused by GNB and the most common organism was Escherichia coli (n = 35, 10.2%), followed by Pseudomonas aeruginosa (n = 10, 2.9%). Pyogenic spondylitis caused by GNB was more frequently associated with the female gender (64.5 vs. 35.5%, P <0.01), preexisting or synchronous genitourinary tract infection (32.3 vs. 2.1%, P< 0.01), and intra-abdominal infection (12.9 vs. 0.4%, P< 0.01) compared to patients with GPC. Although pyogenic spondylitis caused by GNB presented with severe sepsis more frequently (24.2 vs. 11.3%, P = 0.01), the mortality rate (6.0 vs. 5.2%) and the proportion of patients with residual disability (6.0 vs. 9.0%), defined as grade 3 or 4 (P = 0.78) 3 months after completion of treatment, were not significantly different compared to GPC patients. Conclusion GNB should be considered as the etiologic organism when infectious spondylitis develops in a patient with preexisting or synchronous genitourinary tract and intra-abdominal infection. In addition, the mortality rate and clinical outcomes are not significantly different between pyogenic spondylitis caused by GNB and GPC. PMID:25978839

    Based on clinical features alone, pyogenic granuloma can be difficult to differentiate from a peripheral giant cell granuloma, a more aggressive oral lesion that could have consequences such as teeth displacement and alveolar bone resorption. A thorough clinical and radiographic examination is important to determine whether teeth and/or bone are involved. Furthermore, the early onset of puberty in females may increase the prevalence of pyogenic granuloma at a young age. PMID:12116517

    Jost, B H; Songer, J G; Billington, S J

    2001-07-01

    Arcanobacterium pyogenes is an opportunistic pathogen, associated with suppurative infections in domestic animals. In addition to pyolysin, a pore-forming, cholesterol-binding toxin, A. pyogenes expresses a number of putative virulence factors, including several proteases and neuraminidase activity. A 3,009-bp gene, nanH, was cloned and sequenced and conferred neuraminidase activity on an Escherichia coli host strain. The predicted 107-kDa NanH protein displayed similarity to a number of bacterial neuraminidases and contained the RIP/RLP motif and five copies of the Asp box motif found in all bacterial neuraminidases. Recombinant His-tagged NanH was found to have pH and temperature optima of 5.5 to 6.0 and 55 degrees C, respectively. Insertional deletion of the nanH gene resulted in the reduction, but not absence, of neuraminidase activity, indicating the presence of a second neuraminidase gene in A. pyogenes. NanH was localized to the A. pyogenes cell wall. A. pyogenes adhered to HeLa, CHO, and MDBK cells in a washing-resistant manner. However, the nanH mutant was not defective for adherence to epithelial cells. The role of NanH in host epithelial cell adherence may be masked by the presence of a second neuraminidase in A. pyogenes. PMID:11401983

    Summary Objectives Despite over a century of research and the careful scrutiny of many promising targets, there is currently no vaccine available for the prevention of Streptococcus pyogenes infection. Through analysis of the protective, anti-streptococcal components of pooled human immunoglobulin, we previously identified ten highly conserved and invariant S. pyogenes antigens that contribute to anti-streptococcal immunity in the adult population. We sought to emulate population immunity to S. pyogenes through a process of active vaccination, using the antigens targeted by pooled human immunoglobulin. Methods Seven targets were produced recombinantly and mixed to form a multicomponent vaccine (Spy7). Vaccinated mice were challenged with S. pyogenes isolates representing four globally relevant serotypes (M1, M3, M12 and M89) using an established model of invasive disease. Results Vaccination with Spy7 stimulated the production of anti-streptococcal antibodies, and limited systemic dissemination of M1 and M3 S. pyogenes from an intramuscular infection focus. Vaccination additionally attenuated disease severity due to M1 S. pyogenes as evidenced by reduction in weight loss, and modulated cytokine release. Conclusion Spy7 vaccination successfully stimulated the generation of protective anti-streptococcal immunity in vivo. Identification of reactive antigens using pooled human immunoglobulin may represent a novel route to vaccine discovery for extracellular bacteria. PMID:26880087

    Psoas abscess is a rare infectious disease with nonspecific clinical presentation that frequently causes a diagnostic difficulty. Its insidious onset and occult characteristics can cause diagnostic delays. It is classified as primary or secondary. Staphylococcus aureus is the most commonly causative pathogen in primary psoas abscess. Secondary psoas abscess usually occurs as a result of underlying diseases. A high index of clinical suspicion, the past and recent history of the patient, and imaging studies can be helpful in diagnosing the disease. The delay of the treatment is related with high morbidity and mortality rates. In this paper, 54-year-old patient with severe hip pain having an abscess in the psoas muscle due to metastatic cervical carcinoma is presented. PMID:25685574

    2013-01-01

    Salmonella neck infections represent an uncommon cause of focal salmonellosis. While the incidence of nontyphoid salmonellosis is estimated at over 2 million cases annually, extraintestinal manifestations account for less than 1% of cases. This paper describes two patients with Salmonella neck abscesses as the initial presentation of diabetes mellitus. The first patient was diagnosed as having Salmonella enterica serotype Enteritidis sternocleidomastoid pyomyositis and the second patient Salmonella enterica serotype Typhimurium parapharyngeal abscess. Both patients had elevated hemoglobin A1c levels and had not been previously diagnosed with diabetes mellitus. Salmonella spp. should be on the differential as a causative pathogen in patients presenting with neck abscesses and poorly controlled glucose levels. Diabetes may be a risk factor for salmonellosis due to decreased gastric acidity and prolonged gastric transit time. Prompt incision and drainage accompanied by antibiotics remains the treatment of choice for infected neck abscesses. PMID:24307959

    Subperiosteal abscess formation is almost exclusively seen secondary to underlying hematogenous infected osteomyelitis or secondary as a result of a contagious focus. We present an unusual case of a 9-year-old girl with progressive ankle pain due to an isolated subperiosteal abscess of the distal fibula without concomitant osteomyelitis. The subperiosteal abscess was most likely caused by hematogenous spread to the periosteal region of the distal fibula located above the highly vascularized metaphysis. Remarkably, there were no signs of osteomyelitis on either MRI or during surgical inspection. She was successfully treated with debridement and antibiotic therapy. We hypothesize that subperiosteal abscess formation near the metaphysis originates in the periosteal region and not from outward extension from the sinusoidal veins in the intrametaphyseal area to the cortex and subperiosteal region.

    Abstract Hepatic abscess (HA) remains a serious and often difficult to diagnose problem. HAs can be divided into three main categories based on the underlying conditions: infectious, malignant, and iatrogenic. Infectious abscesses include those secondary to direct extension from local infection, systemic bacteremia, and intra-abdominal infections that seed the portal system. However, over the years, the etiologies and risks factors for HA have continued to evolve. Prompt recognition is important for instituting effective management and obtaining good outcomes.

    We report a case of Scedosporium apiosporum brain abscesses in an immunocompetent 69-year-old man with a history of silicosis. Delayed diagnosis and institution of antifungal therapy was associated with neurological impairment, with subsequent complications resulting in death, highlighting the need for early diagnostic aspiration of brain abscesses non-responsive to antibiotics. We propose that, in the absence of identifiable immunosuppression, silicosis may have been a contributing factor to the development of central nervous system infection. PMID:24432222

    Purpose Tuberculosis can be responsible for extensive spinal lesions. Despite the efficacy of medical treatment, surgery is indicated to avoid or correct significant deformity, treat spinal instability, prevent neurological compromise, and to eradicate an extensive tuberculous abscess. In this paper we present our experience in the surgical management of spinal tuberculosis complicated with large abscess. Patients and Methods Fifteen patients with spinal tuberculosis complicated with extensive abscess were identified; and nine of those patients had extension of the infection into the epidural space. The average age at treatment was 34 years old. Seven patients had thoracic infection, seven patients had lumbar infection and one had thoracolumbar infection. Six patients had neurological deficit at presentation. All patients were surgically treated with abscess debridement, spinal stabilization and concurrent antituberculous chemotherapy. A single anterior surgical approach was used in three cases, a posterior approach was used in four others and a combined approach was performed in eight patients. Results Surgical management allowed for effective abscess debridement and sspinal stabilization in this cohort. In combination with antituberculous drugs, surgical treatment resulted in infection eradication and bone fusion in all patients at 24 month average follow-up. Satisfactory neurological outcomes with improved American Spinal Injury Association (ASIA) scores were observed in 100% of patients. Conclusion Surgical treatment for spinal tuberculosis abscess can lead to satisfactory clinical outcomes. PMID:25328472

    Summary Pituitary abscess is a rare life-threating entity that is usually misdiagnosed as a pituitary tumor with a definite diagnosis only made postoperatively. Over the last several decades, advances in healthcare have led to a significant decrease in morbidity and mortality due to pituitary abscess. We report a case of a 34-year-old woman who was admitted to our department for investigation of a pituitary mass and with symptoms of pituitary dysfunction, headaches and impaired vision. During her admission, she developed meningitis-like symptoms and was treated with antibiotics. She eventually underwent transsphenoidal surgery for excision of the pituitary mass. A significant amount of pus was evident intraoperatively; however, no pathogen was isolated. Six months later, the patient was well and had full recovery of the anterior pituitary function. Her menses returned, and she was only on treatment with desmopressin for diabetes insipidus that developed postoperatively. Learning points Pituitary abscess is a rare disease and the reported clinical features vary mimicking other pituitary lesions. The diagnosis of pituitary abscess is often very difficult to make and rarely included in the differential. The histological findings of acute inflammatory infiltration confirm the diagnosis of pituitary abscess. Medical and surgical treatment is usually recommended upon diagnosis of a pituitary abscess.

    Streptococcus pyogenes adapts to different niches encountered in the human host via the activity of numerous regulatory proteins including the Rgg family of transcriptional regulators. The S. pyogenes chromosome encodes four Rgg paralogues designated Rgg1 (RopB), Rgg2 (MutR), Rgg3, and Rgg4 (ComR). In order to understand the role of the Rgg2 protein in the regulation of metabolic and virulence-associated properties of S. pyogenes, the rgg2 gene was inactivated in the M1 serotype strain SF370. Inactivation of rgg2 increased the growth yield of S. pyogenes in THY broth, increased biofilm formation, and increased production of SIC, which is an important virulence factor that inhibits complement mediated lysis. To identify Rgg2-regulated genes, the transcriptomes of SF370 and the rgg2 mutant strains were compared in the middle-exponential and post-exponential phases of growth. Rgg2 was found to control the expression of dozens of genes primarily in the exponential phase of growth, including genes associated with virulence (sse, scpA, slo, nga, mf-3), DNA transformation, and nucleotide metabolism. Inactivation of rgg2 decreased the ability of S. pyogenes to adhere to epithelial cells. In addition, the mutant strain was more sensitive to killing when incubated with human blood and avirulent in a murine bacteremia model. Finally, inoculation of mice with the avirulent rgg2 mutant of S. pyogenes SF370 conferred complete protection to mice subsequently challenged with the wild-type strain. Restoration of an intact rgg2 gene in mutant strain restored the wild-type phenotypes. Overall, the results demonstrate that Rgg2 is an important regulatory protein in S. pyogenes involved in controlling genes associated with both metabolism and virulence. PMID:25486272

    Introduction: Pyogenic granuloma (PG) is a common tumor-like growth of the oral cavity, considered to be of non-neoplastic nature, often caused by constant low-grade trauma as well as poor oral hygiene and maybe due to hormonal disturbances. Surgical excision, and removal of underlying cause in some cases, is the preferred method of treatment as it is only a benign lesion.In order to remove this lesion, scalpel, cryosurgery and laser are used. Currently different lasers, with adequate parameters, are used for the surgery of PG, which include CO2 (Carbon Dioxide Laser), Nd:YAG (Neodymium-Doped Yttrium Aluminium Garnet), Diode and Er Family amongst others. In this present case, due to the proximity of the lesion with dental hard tissue, Er:YAG (Erbium-Doped Yttrium Aluminum Garnet) laser appears to be the more appropriate laser. The application of Laser is also a newly recommended technique. The aim of this study is to assess the stages of treatment, recovery and recurrence of PG when the Er:YAG laser is used. Furthermore this study aims to also evaluate the friendliness of this method with regards to the surgeon (therapist). Case report: A 24-year-old female was referred to the Laser Research Center of Dentistry of Tehran University of Medical Sciences with a complaint of gingival overgrowth and bleeding. This lesion was in the buccal and palatal side of the 5 and 6 maxillary teeth. Treatment plan included an excisional biopsy of the lesion using Er:YAG laser (3W, 300mJ, 10Hz, Short pulse, with contact headpiece). The bones were then cleaned of soft tissue before being smoothed using a curette. The excised specimen was preserved and sent for histopathological examination. Results: The patient reported no pain after surgery and did not use any systemic antibiotics. The patient was satisfied after the surgery. Chlorhexidine mouthwash was given to the patient. Pathology results confirmed Pyogenic granuloma.After 2 weeks, complete healing was observed. The 9-month

    A 20-year review was conducted of children presenting with psoas abscess at two major pediatric hospitals. Eleven children with psoas abscesses were identified. The extreme variability in the clinical presentation of this condition is shown. Psoas abscess was most difficult to differentiate from septic arthritis of the hip in pediatric patients. This study also shows the often circuitous investigative route traversed before arriving at the diagnosis of psoas abscess. Atypical features, such as femoral nerve neurapraxia or bladder irritability in association with hip pain, should alert the clinician to consider psoas abscess. Based on this study, a diagnostic algorithm to differentiate between psoas abscess and septic hip was formulated. PMID:11603678

    Background: We reviewed the literature regarding the pathogenesis, clinical presentation, diagnosis, and management of spinal epidural abscess (SEA). Methods: Utilizing PubMed, we performed a comprehensive review of the literature on SEAs. Results: SEA remains a difficult infectious process to diagnose. This is particularly true in the early stages, when patients remain neurologically intact, and before the classic triad of fever, back pain, and neurologic deficit develop. However, knowledge of risk factors, obtaining serologic markers, and employing magnetic resonance scans facilitate obtaining a prompt and accurate diagnosis. In patients without neurologic deficits, lone medical therapy may prove effective. Conclusions: More prevalent over the previous three decades, SEA remains a rare but deleterious infectious process requiring prompt identification and treatment. Historically, identification of SEA is often elusive, diagnosis is delayed, and clinicians contend that surgical debridement is the cornerstone of treatment. Early surgery leads to more favorable outcomes and preserves neurologic function, particularly in the early stages of disease when minimal or no neurologic deficits are present. The advent of improved imaging modalities, diagnostic techniques, and multidrug antimicrobial agents has enabled medical/spinal surgical consultants to more rapidly diagnose SEA and institute more effective early medical treatment (e.g., data suggest that lone medical therapy may prove effective in the early management of SEA).

    In the experimental animal, desferal (DFO) given intravenously washes out Ga-67 from all tissues. This effect is not uniform: blood activity is reduced very markedly, while liver activity is less affected. Maximal effect of DFO occurs if given close to the Ga-67 injection. When the time interval between the two is increased, the absolute amount of Ga-67 excreted in the urine in excess of the spontaneous excretion is reduced. Administration of DFO does not effect Ga-67 gastrointestinal excretion. In three animal tumor models (EMT-6 sarcoma in Balb/c mice, spontaneous adenocarcinoma in mice, and spontaneous adenocarcinoma in the rabbit) and in sterile abscess-bearing rats, the administration of DFO 24 hrs after Ga-67-citrate improves significantly the target-to-nontarget ratio. Animals given 50 mg/kg DFO I.V. after Ga-67 citrate showed a significant reduction in the whole-body activity as seen in a one-week follow up.

    Autosomal Dominant Polycystic Kidney Disease (ADPKD) is one of the most common monogenic disorders and the leading inheritable cause of end-stage renal disease worldwide. Cystic and noncystic extrarenal manifestations are correlated with variable clinical presentations so that an inherited disorder is now considered a systemic disease. Kidney and liver cystic infections are the most common infectious complications in ADPKD patients. Furthermore, it is well known that ADPKD is commonly associated with colonic diverticular disease which recently has been reported to be linked to increased risk of infection on hemodialysis patients. Herein, we present a case of anterior abdominal wall abscess caused by Enterococcus faecalis in a patient with ADPKD undergoing hemodialysis. Although the precise pathway of infection remains uncertain, the previous medical history as well as the clinical course of our patient led us to hypothesize an alternative route of infection from the gastrointestinal tract through an aberrant intestinal barrier into the bloodstream and eventually to an atypical location.

    Having no known environmental reservoir, Streptococcus pyogenes, a bacterium responsible for a wider variety of human diseases than any other bacterial species, must rely on its host for metabolic substrates. Although a streptococcal aldolase, LacD.1, has been adapted to virulence gene regulation, both LacD.1 and a paralogous protein, LacD.2, are predicted to function in the tagatose 6-phosphate pathway for lactose and galactose utilization. In order to gain insight into the mechanism of the LacD.1 regulatory pathway and the role of genome context in the emergence of LacD.1's novel regulatory functions, we compared the function and regulation of the Lac.1 and Lac.2 loci. The Lac.1 operon is not inducible, and regulation by LacD.1 is independent of a functional tagatose 6-phosphate pathway and enhanced by the conserved truncation of upstream Lac.1 genes. In contrast, Lac.2 expression is sensitive to environmental carbohydrates, and LacD.2, not LacD.1, contributes to growth on galactose. Thus, we conclude that the Lac.1 locus has been specialized to participate in regulation, leaving efficient utilization of carbohydrate sources to the Lac.2 locus. The adaptation of LacD for transcription regulation may be an underappreciated strategy among prokaryotes, as homologues of this multifaceted enzyme are present in a broad range of species.

    Dale, R C

    Streptococcus pyogenes (or group A beta hemolytic streptococcus) is a pathogenic bacterium that can give rise to a range of invasive and autoimmune diseases, although it is more widely known as the cause of tonsillitis. It is particularly interesting to note that this germ only causes disease in humans. For many years it has been acknowledged that it can cause an autoimmune brain disease (Sydenham s chorea). Yet, the spectrum of post streptococcal brain disorders has recently been extended to include other movement disorders such as tics or dystonia. A number of systematic psychiatric studies have shown that certain emotional disorders generally accompany the movement disorder (particularly, obsessive compulsive disorder). The proposed pathogenetic mechanism is that of a neuronal dysfunction in which antibodies play a mediating role. The antibodies that are produced after the streptococcal infection cross react with neuronal proteins, and more especially so in individuals with a propensity. This represents a possible model of immunological mimicry and its potential importance with respect to certain idiopathic disorders such as Tourette syndrome and obsessive compulsive disorder.

    Pyogenic granuloma (PG) is a benign non-neoplastic mucocutaneous lesion. It is a reactional response to constant minor trauma and might be related to hormonal changes. In the mouth, PG is manifested as a sessile or pedunculated, resilient, erythematous, exophytic and painful papule or nodule with a smooth or lobulated surface that bleeds easily. PG preferentially affects the gingiva, but may also occur on the lips, tongue, oral mucosa and palate. The most common treatment is surgical excision. This paper describes a mucocutaneous PG on the upper lip, analyzing the clinical characteristics and discussing the features that distinguish this lesion from other similar oral mucosa lesions. The diagnosis of oral lesions is complex and leads the dentist to consider distinct lesions with different diagnostic methods. This case report with a 4 year-follow-up calls the attention to the uncommon mucocutaneous labial location of PG and to the fact that surgical excision is the safest method for diagnosis and treatment of PG of the lip, even when involving the mucosa and skin.

    Streptococcus pyogenes (group A streptococci, GAS) is an exclusive human bacterial pathogen. The virulence potential of this species is tremendous. Interactions with humans range from asymptomatic carriage over mild and superficial infections of skin and mucosal membranes up to systemic purulent toxic-invasive disease manifestations. Particularly the latter are a severe threat for predisposed patients and lead to significant death tolls worldwide. This places GAS among the most important Gram-positive bacterial pathogens. Many recent reviews have highlighted the GAS repertoire of virulence factors, regulators and regulatory circuits/networks that enable GAS to colonize the host and to deal with all levels of the host immune defense. This covers in vitro and in vivo studies, including animal infection studies based on mice and more relevant, macaque monkeys. It is now appreciated that GAS, like many other bacterial species, do not necessarily exclusively live in a planktonic lifestyle. GAS is capable of microcolony and biofilm formation on host cells and tissues. We are now beginning to understand that this feature significantly contributes to GAS pathogenesis. In this review we will discuss the current knowledge on GAS biofilm formation, the biofilm-phenotype associated virulence factors, regulatory aspects of biofilm formation, the clinical relevance, and finally contemporary treatment regimens and future treatment options.

    Hematogenous pyogenic vertebral osteomyelitis (HPVO) continues to be a diagnostic problem for clinicians due to nonspecific presentation of the disease (1,2). We reviewed our experience of the last 10 years to determine the diagnostic usefulness of radionuclide bone studies in this disease. We found 15 patients whose primary diagnosis was HPVO. Of the 15 patients, 12 had (99mTc)MDP bone scans which were all positive. Five of the 12 patients had positive (/sup 67/Ga)citrate scans and one patient with chronic active HPVO had negative /sup 67/Ga and (/sup 111/In)WBC bone images. At the same time, three patients' spine x-rays and one patient's CT scan of the vertebra were normal. Additionally, in three patients spine x-rays were interpreted as consistent with degenerative joint disease that contributed to the delay of the diagnosis. We conclude that when HPVO is suspected an abnormal (99mTc)MDP bone image increases the probability of the disease, even if the x-rays and CT scans of the spine are normal. An abnormal /sup 67/Ga image following an abnormal 99mTc bone image increases the specificity of the diagnosis. Normal (99mTc)MDP and (/sup 67/Ga)citrate bone images of the vertebra virtually exclude the diagnosis of HPVO.

    The aim of this study was to investigate the emm types and superantigen profiles of bacteraemic group A streptococcal (GAS; Streptococcus pyogenes) isolates and to detect possible associations between the molecular characteristics of isolates and the clinical presentations of disease. In this population-based study, 87 bacteraemic GAS isolates from adult patients in Pirkanmaa Health District (HD), Finland, during the period 1995-2004 were emm typed and genotyped for superantigen (SAg) profiles. The epidemiological and clinical data of the patients were analysed with the microbiological characterisation data. Among the 87 isolates, 18 different emm types were found. emm1, emm28 and emm81 were the three most common types, covering 52% of isolates. The prevalence of specific emm types showed high variability during the 10-year study period. We could not find any association between the emm type and clinical features of bacteraemic infection, such as underlying diseases, disease manifestations or case fatality. Of nine superantigen genes examined, speA and speC were identified in 20 and 30% of the strains, respectively. No association was found between disease manifestation and the presence of single superantigen genes. The 26-valent GAS vaccine would have covered only 62% of isolates causing invasive disease in Pirkanmaa HD during the study period. PMID:21877175

    Cutaneous toxicities under therapy with selective BRAF inhibitors such as vemurafenib or encorafenib (LGX818) are frequent, including plantar hyperkeratosis, squamous cell carcinoma, and second primary melanoma. Pyogenic granuloma is a benign, rapidly growing, eruptive hemangioma that often bleeds and ulcerates. Common causes are mechanical trauma and cast immobilization, as well as multiple drugs such as retinoids and antineoplastic agents. However, the development of pyogenic granuloma under treatment with encorafenib (LGX818) has not yet been reported. These three cases might be further examples for paradoxical activation of the mitogen-activated protein kinase pathway. We report three male patients with metastatic BRAFV600E-mutated melanoma who developed pyogenic granulomas 16, 10, and 12 weeks after treatment initiation with the selective BRAF inhibitors vemurafenib or encorafenib (LGX818). Except for one patient receiving retinoids, the clinical history for other frequent causes of pyogenic granuloma was negative. Pyogenic granulomas are not listed in the drugs investigator brochure but seem to be associated with selective BRAF inhibitors and might be a cutaneous phenomenon of paradoxical mitogen-activated protein kinase pathway activation. This correlation has to be confirmed by further observations. PMID:27116335

    The infection of epithelial cells is a necessary step for Mycobacterium bovis BCG dissemination, but the mechanism of mycobacterial epithelial interactions is not completely understood. Similarly, Streptococcus pyogenes is a strictly human pathogen that favorably colonizes the skin and the pharynx. Effective cytokine secretion is essential in order to fabricate a suitable inflammatory response against an infection. In this data article, the cytokine profile in BCG and S. pyogenes activated THP-1 cell line in media after the acute phase of infection by ELISA is described. The interleukin-8 level was increased in response to both BCG and S. pyogenes, but was quite prominent after 24 h and further increased upto 72 h post infection. On the other hand, an increase in IL-6 response to S. pyogenes was observed while there was no response to BCG even after 48 h of infection. A low level of TNF-α was detected upon BCG and S. pyogenes infection. PMID:27014727

    A 67-year-old woman with non-insulin dependent diabetes mellitus with a history consistent with a right axillary abscess, presented to her general practitioner (GP). A diagnosis of folliculitis was made and the GP started a course of flucloxacillin. Despite antibiotics, the patient's symptoms worsened and the abscess increased in size. This prompted her GP to perform an incision and drainage procedure of the abscess. The practice nurse subsequently oversaw the follow-up care of the wound. Two months after the incision and drainage, and after regular wound dressing, the patient was referred to the acute surgical team with a complicated, non-healing right axillary abscess cavity and associated generalised right breast cellulitis. There was no history of breast symptoms prior to the onset of the axillary abscess. The patient underwent wound debridement, washout and application of negative pressure vacuum therapy. Biopsies revealed primary breast lymphoma (B-cell). She underwent radical chemotherapy and is currently in remission. PMID:26446318

    Streptococcus pyogenes is commonly found on pharynx, mouth and rarely on skin, lower gastrointestinal tract. It is a potential pathogen causing tonsillitis, pneumonia, endocarditis. The present study was undertaken to study the effects of low shear modeled microgravity on growth, morphology, antibiotic resistance, cross-stress resistance to various stresses and alteration in gene expression of S. pyogenes. The growth analysis performed using UV–Visible spectroscopy indicated decrease in growth of S. pyogenes under low shear modeled microgravity. Morphological analysis by Bio-transmission electron microscopy (TEM), Bio-scanning electron microscopy (SEM) did not reveal much difference between normal and low shear modeled microgravity grown S. pyogenes. The sensitivity of S. pyogenes to antibiotics ampicillin, penicillin, streptomycin, kanamycin, hygromycin, rifampicin indicates that the bacterium is resistant to hygromycin. Further S. pyogenes cultured under low shear modeled microgravity was found to be more sensitive to ampicillin and rifampicin as compared with normal gravity grown S. pyogenes. The bacteria were tested for the acid, osmotic, temperature and oxidative cross stress resistances. The gene expression of S. pyogenes under low shear modeled microgravity analyzed by microarray revealed upregulation of 26 genes and down regulation of 22 genes by a fold change of 1.5.

    Introduction Anorectal abscess is one of the most common anorectal conditions encountered in practice. However, such abscesses may rarely extend upward and cause life-threatening medical conditions. Presentation of case A 53-year-old woman presented with symptoms of anorectal abscess and evidence of severe inflammatory response and acute kidney injury. Computed tomography revealed a widespread abscess extending to the bilateral retroperitoneal spaces. Surgical drainage was performed via a totally extraperitoneal approach through a lower midline abdominal incision, and the patient had a rapid and uncomplicated recovery. Discussion Although retroperitoneal abscesses originating from the anorectal region are rare, they are life-threating events that require immediate treatment. Percutaneous abscess drainage has been recently evolved; however, surgical drainage is required sometimes that may be challenging, particularly in the case of widespread abscesses, as in our case. Conclusion The midline extraperitoneal approach reported here might be an effective surgical option for patients with bilateral widespread retroperitoneal abscesses. PMID:26701843

    Radionuclide liver scans and gray scale ultrasonography of the liver were compared in 456 patients with various abnormalities including normal variants, jaundice, abscesses, and metastatic diseases. In general the better resolution of sonography detected smaller and deeper focal lesions than nuclide scans, but nuclide studies were more informative in hepatocellular disorders. Nuclide studies frequently demonstrated lesions that could be further delineated by sonography as either cystic or solid. This ability was of particular significance in isolated liver lesions found during metastatic surveys. PMID:6823576

    Pyogenic granuloma is defined as a benign neoplasm of vascular phenotype. This case describes the clinical and histopathological features of a gigantic mucogingival pyogenic granuloma, in a 14-year-old healthy black boy. This exophytic gray-purple mass, related to a toothpick injury, had more than twelve-month evolution on the anterior mandible involving lingual area besides to the floor of the mouth pressing the right salivary duct. Conservative excision was performed, followed by uncomplicated healing with no recurrence in two years. The histopathological examination reported a pyogenic granuloma (lobular capillary haemangioma). The authors provide a discussion of the presurgical differential diagnosis of the lesion. This case report presents an extremely uncommon location of a gigantic pyogenic granuloma, involving mucogingival complex and affecting the salivary outflow. This clinical manuscript may shed light on the controversies about possible mechanisms inducing oral pyogenic granuloma. PMID:24987485

    Pyogenic granuloma is tumor-like proliferation to a nonspecific infection. Clinically, pyogenic granuloma presents as sessile or pedunculated exophytic mass with a smooth or lobulated surface which has a tendency to bleed easily. These lesions tend to occur slightly more in females, frequently involving the gingiva of the maxillary region. Histologically, these lesions show an excessive proliferation of vascular type of connective tissue to a nonspecific infection. The most common treatment is surgical excision with eradication of local irritants. This case report describes a pyogenic granuloma on the labial mucosa in a 33-year-old male, discussing the clinical features and histopathologic features that distinguish this lesion from other similar oral mucosa lesions.

    Background. Although the incidence of pregnancy-associated pyogenic sacroiliitis is low, it is associated with significant morbidity and mortality. Timely diagnosis of the condition is challenging due to its nonspecific clinical features. Case. A 31-year-old primigravida had an uncomplicated pregnancy and labour. Postpartum, she developed persistent fever and debilitating hip pain on ambulation. White cell count was normal (7.3 × 109/L) and C-reactive protein was elevated (468.4 mg/L). Streptococcus pyogenes was identified on vaginal swabs and blood cultures, and a pelvic magnetic resonance imaging scan revealed bilateral sacroiliitis. Conclusion. Pyogenic sacroiliitis is a potentially lethal cause of postpartum pain. It should be considered as a differential diagnosis even in low-risk women who present with debilitating pelvic pain in or around pregnancy, particularly when initial therapy appears unsuccessful. PMID:24396619

    The human pathogen Streptococcus pyogenes primarily infects the upper respiratory tract and skin, but occasionally it disseminates and causes severe invasive disease with high mortality. This study revealed that the activity of extracellular EndoS, which hydrolyzes the functionally important N-linked oligosaccharides on opsonizing immunoglobulin G (IgG), contributes to increased survival of S. pyogenes in human blood ex vivo. The inability to kill the bacteria is due to reduced binding of IgG to Fc receptors and impaired classical pathway-mediated activation of complement. In addition, the activity of extracellular SpeB, which cleaves IgG into Fc and Fab fragments, also increases bacterial survival. This suggests that S. pyogenes expresses two enzymes, EndoS and SpeB, which modulate IgG by different mechanisms in order to evade the adaptive immune system. PMID:12438337

    Pyogenic sacroiliitis and pyomyositis are uncommon infectious diseases and their diagnoses are often delayed. They are typically seen in children and young adults and are rare in middle-aged people especially in those affected by rheumatic diseases. We present the first case of a Staphylococcus aureus related pyogenic sacroiliitis associated with iliacus and gluteal pyomyositis occurring in a patient with systemic lupus erythematosus. Antibiotic treatment was administered for a total of 6 weeks with a total recovery. Pyogenic sacroiliitis and pyomyositis, although remaining rare events, should be remembered as severe complications in immunosuppressed patients with inflammatory diseases. Early clinical suspicion, imaging diagnosis, and adequate therapy are decisive for the satisfactory outcome. PMID:25165609

    Pyogenic granuloma is a commonly occurring inflammatory hyperplasia of the skin and oral mucosa. It is not associated with pus as its name suggests and histologically it resembles an angiomatous lesion rather than a granulomatous lesion. It is known by a variety of names such as Crocker and Hartzell's disease, granuloma pyogenicum, granuloma pediculatum benignum, benign vascular tumor and during pregnancy as granuloma gravidarum. This tumor like growth is considered to be non-neoplastic in nature and it presents itself in the oral cavity in various clinical and histological forms. Due to its frequent occurrence in the oral cavity, especially the gingiva, this article presents a case report of a large pyogenic granuloma of the gingiva and its management, reviews the literature and discusses why the term “pyogenic granuloma” is a misnomer.

    The postoperative diagnostic imaging examinations of 44 children who underwent 59 orthotopic liver transplantations were reviewed. The imaging modalities used for the evaluation of suspected complications include plain roentgenography, ultrasonography (US), computed tomography (CT), nuclear scintigraphy, arteriography, percutaneous and operative cholangiography, and endoscopic retrograde cholangiopancreatography. The main postoperative complications included ischemia, thrombosis (hepatic artery and portal vein), infarction, obstruction or leakage of the biliary anastomosis, hepatic and perihepatic infection, and allograft rejection. US, the most frequently used abdominal imaging modality, was best suited for detection of biliary duct dilatation, fluid collections in or around the transplanted liver, and hepatic arterial, inferior vena caval, and portal vein thrombosis. CT was especially helpful in corroborating findings of infection and in locating abscesses. Technetium 99m sulfur colloid (early- and late-phase imaging) provided a sensitive, although nonspecific, means of assessing allograft vascularization and morphology. Angiography showed vascularity most clearly, and cholangiography was the most useful In the assessment of bile duct patency. A diagnostic imaging algorithm is proposed for evaluation of suspected complications. PMID:3901104

    Odontogenic infections can spread to any organ of the body and in some cases cause life threatening infections. We report a case of multiple odontogenic brain abscesses resulting from undetected tooth decay. Whereas most odontogenic brain abscesses occur following dental treatment, this report documents brain abscesses prior to dental treatment, signifying the dangers of covert dental infections. This case report updates the literature on the topic of odontogenic brain abscesses. PMID:22524927

    Psoas abscesses are classified into primary or secondary according to infectious etiology. However, the psoas abscess caused by actinomycete together with Escherichia coli infection is very rare. Here we report a case of psoas abscess caused by actinomycete together with Escherichia coli infection in a young woman. The disease was treated successfully. A literature review of psoas abscess in relation to its etiology, identification, and difficulties in the treatment is also presented. PMID:25356161

    Anastomoses often leak after esophageal surgery; if they are not detected in time, leaks can give rise to complications like fluid collections, superinfections, and mediastinitis. Although these complications usually require surgical treatment, different series of patients successfully treated with conservative or minimally invasive approaches have been reported. We present the case of a patient who developed a mediastinal abscess after epiphrenic diverticulectomy. We treated the abscess with US-guided percutaneous transhepatic drainage to avoid surgical reintervention. Although other cases of a transhepatic approach to thoracic lesions have been reported, to our knowledge this is the first report of this technique in mediastinal abscesses. We recommend that transhepatic drainage be considered a therapeutic option in the management of these complications. PMID:22464798

    Brain abscess formation as a sequelae of community-acquired pneumococcal meningitis is extremely rare, accounting for less than 1% of all meningitis complications. Although metastatic seeding from a distal peripheral septic focus has been observed, this phenomenon most commonly occurs in the context of ear, nose and throat infections, post-cranial neurosurgical procedures, traumatic open cranial injury, or immunosuppression. We present the case of a man, 61 years old, on etanercept therapy for ankylosing spondylitis who developed multiple brain abscesses as a complication of pneumococcal meningitis. We believe that the predisposition to this extremely rare complication of a particularly aggressive pneumococcal meningitis was most likely due to the underlying immunosuppression resulting from etanercept therapy. As far as we know, this case is the first report linking multiple brain abscess formation in a patient with community-acquired pneumococcal meningitis with etanercept therapy. PMID:22634540

    We report a case of a middle aged, man with diabetes who presented with dysphagia and odynophagia. On evaluation, he was diagnosed to have an acute prevertebral abscess with an unusual aetiology, an infected pseudocyst of pancreas. Contrast-enhanced CT revealed an enhancing collection in the prevertebral space extending to the retrogastric space and communicating with the body of the pancreas via the oesophageal hiatus. Transoral incision and drainage of the prevertebral abscess were performed. Nasogastric tube was placed in the prevertebral space for continuous drainage and daily irrigation. Supportive intravenous broad spectrum antibiotic therapy along with the surgical intervention led to the resolution of the prevertebral abscess and the infected pancreatic pseudocyst. PMID:24408943

    Listeria monocytogenes is an uncommon cause of illness in the general population. Meningoencephalitis is the most common central nervous system (CNS) manifestation of listeriosis. However, brain abscess represents 1-10% of all CNS listeriosis. To our knowledge, L. monocytogenes brain abscess in multiple myeloma patients has not been previously reported. Thus we report a 58-year-old male patient with multiple myeloma who developed a brain abscess due to L. monocytogenes. Due to a history of penicillin allergy, he was treated with intravenous trimethoprim/sulfamoxazole (TMP-SMX) for a total of 12 weeks, and gentamicin for the first two weeks, followed by oral therapy of TMP-SMX for a total of nine months. He is alive six and a half years after the diagnosis of myeloma with occasional brief seizures despite being on two anticonvulsants. PMID:21252468

    Midurethral slings (MUS) have been used for female stress urinary incontinence throughout the past decade on a worldwide scale. Although this minimally invasive treatment has high success rates, formation of groin abscesses, as well as vaginal and urethral erosions, can occur after the procedure. We report a patient presenting with groin abscess and sinus tract formation after a transobturator tape procedure. The patient exhibited a swollen sinus tract, which drained the abscess at the site of the tape entry to the obturator foramen within her inner left groin. She was referred to our department after unsuccessful medical and surgical treatments. Surgical exploration revealed a forgotten MUS connector located between the mesh and hook within the skin incision. To the best of our knowledge, this is the first report of such a case.

    Summary Background: Rhodococcus species are relatively rare human pathogens, but are being increasingly recognized as causes of infection especially in immunosuppressed patients. Case Report: We present a case of Rhodococcus lung abscess in a patient 10 months post-cadaveric renal transplant, successfully treated with a combination of antibiotics. She required a prolonged course of oral antibiotics for 6 months. She did not require surgical intervention. Chest X-rays and CT thorax showed complete resolution of the initial lesion. We also review the medical literature related to Rhodococcus infection in patients with renal transplantation. Rhodococcus infection should be considered as in the differential diagnosis of immunosuppressed patients who present with lung abscess/mass. Conclusions: A literature review indicates this is a potentially fatal condition with disseminated sepsis/abscesses. PMID:23569526

    The authors report a case of abscess in the obturator internus muscle, which is a rare occurrence. It was managed with antibiotics and surgical intervention was not necessary. Pyomyositis involving the muscles around the hip needs to be differentiated from septic arthritis and transient synovitis of the hip because these pathologies more commonly afflict this joint. However, when present, abscesses usually affect the psoas or the glutei. Only rarely is the obturator internus involved by the abscess. Magnetic resonance imaging is the imaging modality of choice to image the obturator internus and to ascertain the diagnosis. Lack of awareness of the existence of this condition leads to a delay in the correct diagnosis. PMID:19471173
