Little is known about the relationship between proton pump inhibitors use and pyogenic liver abscess. The objective of this study was to evaluate the correlation between proton pump inhibitors 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. Subjects aged 20 to 84 who experienced their first episode of pyogenic liver abscess were enrolled as the case group (n = 1372). Randomly selected subjects aged 20 to 84 without pyogenic liver abscess were enrolled as the control group (n = 1372). Current use, early use, and late use of proton pump inhibitors was defined as subjects whose last one tablet for proton pump inhibitors was noted ≤30 days, between 31 to 90 days and ≥91 days before the date of admission for pyogenic liver abscess. Subjects who never received a prescription for proton pump inhibitors were defined as nonusers of proton pump inhibitors. A multivariable unconditional logistic regression model was used to measure the odds ratio and 95% confidence interval to evaluate the correlation between proton pump inhibitors use and pyogenic liver abscess. After adjusting for confounders, the adjusted odds ratio of pyogenic liver abscess was 7.59 for subjects with current use of proton pump inhibitors (95% confidence interval 5.05, 11.4), when compared with nonusers. Current use of proton pump inhibitors is associated with a greater risk of pyogenic liver abscess.

To report the first case of endogenous Klebsiella endophthalmitis associated with liver abscess in Iran. A 79-year-old man was referred to our hospital due to severe pain and visual loss in the left eye. On physical examination, conjunctival hyperemia, corneal edema, hypopyon and severe vitreous cellular reaction were identified in the left eye; however, yellowish conjunctival discoloration was more apparent in the right eye. Abdominal CT scan showed a right liver lobe abscess that was confirmed by sonographically guided percutaneous liver mass biopsy. Blood, vitreous and liver mass aspirate cultures revealed Klebsiella pneumoniae growth. The patient was thus diagnosed with endogenous Klebsiella endophthalmitis secondary to bacteremia associated with liver abscess. This report suggests that, rather than being confined to Taiwan, endogenous endophthalmitis secondary to a liver abscess due to K. pneumoniae may be a global problem. Therefore, physicians should be aware of the possibility of endophthalmitis whenever a patient with K. pneumoniae liver abscess complains of ocular symptoms.

Tuberculous liver abscess is a rare disease entity even in endemic areas of Mycobacterium tuberculosis. It is usually accompanied by pulmonary tuberculosis or enteric tuberculosis. Further, an isolated tuberculous liver abscess is extremely rare. The disease is diagnosed by laparotomy or postmortem autopsy in most cases, and some authors adopted a 9-month antituberculosis regimen. We herein report a case of an isolated tuberculous liver abscess that initially manifested as persistent fever and general malaise, which was diagnosed by liver biopsy and treated successfully with a 6-month antituberculosis regimen and percutaneous abscess drainage.

Klebsiella pneumoniae liver abscess in diabetic patients: association of glycemic control with the clinical characteristics

PubMed Central

2013-01-01

Background Klebsiella pneumoniae liver abscess (KPLA) has been reported with increasing frequency in East Asian countries in the past 3 decades, especially in Taiwan and Korea. Diabetes is a well-known risk factor for KPLA and highly associated with septic metastatic complications from KPLA. We investigated the association of glycemic control in diabetic patients with the clinical characteristics of KPLA in Taiwan. Methods Adult diabetic patients with KPLA were identified retrospectively in a medical center from January 2007 to January 2012. Clinical characteristics were compared among patients with different levels of current hemoglobin A1c (HbA1c). Risk factors for metastatic infection from KPLA were analyzed. Results Patients with uncontrolled glycemia (HbA1c ≥ 7%) were significantly younger than those with controlled glycemia (HbA1c < 7%). Patients with uncontrolled glycemia had the trend to have a higher rate of gas-forming liver abscess, cryptogenic liver abscess, and metastatic infection than those with controlled glycemia. Cryptogenic liver abscess and metastatic infection were more common in the poor glycemic control group (HbA1c value >; 10%) after adjustment with age. HbA1c level and abscess < 5 cm were independent risk factors for metastatic complications from KPLA. Conclusions Glycemic control in diabetic patients played an essential role in the clinical characteristics of KPLA, especially in metastatic complications from KPLA. PMID:23363608

Background/Aims Many parasites induce changes in the lipid profiles of the host. Cholesterol increases the virulence of Entamoeba histolytica in animal models and in vitro culture. This study aimed to determine, in patients with an amebic liver abscess, the correlation between cholesterol and other features, such as the size and number of abscesses, standard hematological and serum chemistry profiles, liver tests, and duration of hospital stay. Methods A total of 108 patients with an amebic liver abscess and 140 clinically healthy volunteers were investigated. Cholesterol and triglycerides were measured in the sera. The data from medical observations and laboratory tests were obtained from the clinical records. Results A total of 93% of patients with an amebic liver abscess showed hypocholesterolemia not related to any of the studied parameters. Liver function tests correlated with the size of the abscess. The most severe cases of amebic liver disease or death were found in patients whose cholesterol levels continued to decrease despite receiving antiamebic treatment and hospital care. Conclusions Our results show that the hypocholesterolemia observed in patients with an amebic liver abscess is not related to any of the clinical and laboratory features analyzed. This is the first study relating hypocholesterolemia to severity of hepatic amebiasis. PMID:25071907

Pyogenic liver abscess is a rare cause of hospitalization, related to a mortality rate ranging between 15% and 19%. Treatment of choice is represented by image-guided percutaneous drainage in combination with antibiotic therapy but, in some selected cases, surgical treatment is necessary. In extremely rare cases, spontaneous rupture of liver abscess may occur, free in the peritoneal cavity or in neighboring organs, an event which is generally considered a surgical emergency. A 95-years-old woman was hospitalized with fever, upper abdominal pain, mild dyspepsia and massive swelling of the anterior abdominal wall. Computed tomography revealed an oval mass located in the abdominal wall of 12cm×14cm×7cm, in continuity with an abscess of the left hepatic lobe. Because Proteus mirabilis was detected in both the liver abscess and the abdominal wall abscess, the patient was diagnosed with a ruptured pyogenic liver abscess. After spontaneous drainage to the exterior of the hepato-parietal abscess, she was successfully treated with antibiotics alone. Pyogenic liver abscess is a serious and life-threatening illness. Abscess rupture might occur. Many authors consider this complication a surgical emergency, but the site of abscess rupture changes the clinical history of the disease: in case of free rupture into the peritoneum, emergency surgery is mandatory, while a rupture localized in neighboring tissues or organs can be successfully treated by a combination of systemic antibiotics and fine needle aspiration and/or percutaneous drainage of the abscess.

Hepatic liver abscesses are often misdiagnosed on initial presentation because pyogenic liver lesions are a rare occurrence in the United States. This leads to a delay in proper treatment and results in increasing morbidity and mortality. Our case report demonstrates the atypical presentation of a hepatic liver abscess in the elderly. The source of infection was found to be periapical abscesses of the teeth, which subsequently seeded the portal blood stream of our patient. Our findings validate the potential hazard of Viridans streptococci and illustrate how untreated dental infections can serve as a reservoir for a systemic infection. PMID:29796365

Recently, a striking new clinical manifestation of Klebsiella pneumoniae (KP) infection referred to as invasive KP liver abscess syndrome (IKPLAS), defined by liver abscess with contemporaneous metastatic KP infections at other body sites has been documented. Until now, however, there have been relatively few reports regarding its radiologic features. To describe the clinical and radiological features of IKPLAS patients, and to compare them with those with KP liver abscess without metastatic infections to ascertain possible predictors of IKPLAS. From January 2008 to May 2010, 35 patients (26 men and 9 women; mean age, 59.4 years) with both liver abscess and metastatic KP infections were diagnosed with IKPLAS. Their clinical and radiological features were retrospectively evaluated and compared with those of 25 contemporaneous non-metastatic patients to investigate predictive factors for metastatic infections. The rate of intensive care unit admissions and overall mortality was 34.3% and 17.1% in IKPLAS patients, and was significantly higher than those of the non-metastatic group (8% and 0%, respectively). As for metastatic infections, the lung was the most common site and multiple nodules or masses (n = 9) were the most common manifestations. Univariate analysis revealed that liver abscess ≤5.8 cm, bilobar involvement of abscess and altered mentality were significantly related with IKPLAS. At multivariate analysis, liver abscess ≤5.8 cm was proven to be a significant independent predictor of IKPLAS (OR, 3.6; P = 0.038). In addition, altered mentality was present solely in IKPLAS (25.7% vs. 0%) although its P value (P = 0.052) did not reach a statistical significance at multivariate analysis. IKPLAS has significantly worse prognosis than non-metastatic KP abscess patients. In patients with KP liver abscess, liver abscess ≤5.8 cm can be used as an independent predictor of IKPLAS and altered mentality as a very specific feature in diagnosing IKPLAS. © 2013 The Foundation Acta Radiologica.

An unusual case of infective endocarditis and concurrent multiple liver abscesses both caused by Streptococcus anginosus in a splenectomised patient is reported. The microorganism is a very rare cause of endocarditis and its presentation with multiple liver abscesses is highly unusual. It was initially misdiagnosed as Streptococcus sanguinis and issues relating to the different clinical presentations of S. anginosus including the rare cases of endocarditis, the role of the patient's splenectomy and problems that may contribute to its potential laboratory misidentifications are discussed. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

A 27-year-old man with a 4-month history of treatment for miliary tuberculosis at another hospital was admitted to our hospital for continued treatment. Computed tomography showed new lesions in the S8 area of the liver and spleen, despite resolution of chest radiographic findings. Because these new lesions were still present after 8 months of treatment, we performed laparoscopic drainage of the liver abscess. Purulent material drained from the lesion revealed positive polymerase chain reaction results for Mycobacterium tuberculosis, and identification of granuloma with infiltrating lymphocytes and plasma cells confirmed the diagnosis of tubercular liver abscess. Pathological changes in the spleen over the clinical course were also regarded as representing tubercular abscess. Postoperative course was good, and tuberculosis treatment ended after 12 months. Tubercular liver abscess subsequently showed prominent reduction, and the tubercular splenic abscess disappeared on abdominal ultrasonography. Tubercular hepatosplenic abscesses appearing during tubercular treatment are rare. We report this valuable case in which laparoscopic drainage of a liver abscess proved useful for diagnosis and treatment.

Fourteen percent of U.S. cattle slaughtered in 2011 had liver abscesses, resulting in reduced carcass weight, quality, and value. Liver abscesses can result from a common bacterial cause, , which inhabits rumen lesions caused by acidosis and subsequently escapes into the blood stream, is filtered by the liver, and causes abscesses in the liver. Our aim was to identify SNP associated with liver abscesses in beef cattle. We used lung samples as a DNA source because they have low economic value, they have abundant DNA, and we had unrestricted access to sample them. We collected 2,304 lung samples from a beef processing plant: 1,152 from animals with liver abscess and 1,152 from animals without liver abscess. Lung tissue from pairs of animals, 1 with abscesses and another without, were collected from near one another on the viscera table to ensure that pairs of phenotypically extreme animals came from the same lot. Within each phenotype (abscess or no abscess), cattle were pooled by slaughter sequence into 12 pools of 96 cattle for each phenotype for a total of 24 pools. The pools were constructed by equal volume of frozen lung tissue from each animal. The DNA needed to allelotype each pool was then extracted from pooled lung tissue and the BovineHD Bead Array (777,962 SNP) was run on all 24 pools. Total intensity (TI), an indicator of copy number variants, was the sum of intensities from red and green dyes. Pooling allele frequency (PAF) was red dye intensity divided TI. Total intensity and PAF were weighted by the inverse of their respective genomic covariance matrices computed over all SNP across the genome. A false discovery rate ≤ 5% was achieved for 15 SNP for PAF and 20 SNP for TI. Genes within 50 kbp from significant SNP were in diverse pathways including maintenance of pH homeostasis in the gastrointestinal tract, maintain immune defenses in the liver, migration of leukocytes from the blood into infected tissues, transport of glutamine into the kidney in response to acidosis to facilitate production of bicarbonate to increase pH, aggregate platelets to liver injury to facilitate liver repair, and facilitate axon guidance. Evidence from the 35 detected SNP associations combined with evidence of polygenic variation indicate that there is adequate genetic variation in incidence rate of liver abscesses, which could be exploited to select sires for reduced susceptibility to subacute acidosis and associated liver abscess.

Liver abscesses occurring just below the diaphragm can penetrate or perforate the thoracic cavity, resulting in lung abscess or pyothorax. Although surgical or percutaneous transpleural drainage is often required in such cases, the latter approach has some risks, including hemothorax and bronchopleural fistula formation when the cavity is surrounded by normal lung parenchyma. The present report describes a treatment technique of percutaneous transhepatic drainage through the diaphragmatic fistula to avoid the risks of a transpulmonary approach in a case of lung abscess caused by a penetrating liver abscess.

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

We report 2 cases of laparoscopic surgery for patients who had liver abscess as the initial manifestation of underlying colon cancer. The first case was in an 80-year-old woman who presented to our hospital with a diagnosis ofliver abscess. Percutaneous transhepatic abscess drainage(PTAD)was performed as initial treatment. Subsequent colonoscopy revealed a type 1 tumor in the cecum, and biopsy results ofthe mass indicated adenocarcinoma. The patient underwent laparoscopic right hemicolectomy as curative treatment. The pathological findings were as follows: tub1, T2, N0, M0 and Stage I . Two years later, she remains disease free. The second case was in a 59-year-old man with liver abscess. Colonoscopy also revealed a type 2 tumor in the sigmoid colon. After treatment of the liver abscess with PTAD, laparoscopic sigmoidectomy was performed with a preoperative diagnosis of sigmoid colon cancer. The pathological findings were as follows: tub2, T3, N0, M0 and Stage II . Lung metastases appeared 10 months after surgery, and systemic chemotherapy was administered. In conclusion, liver abscess is occasionally caused by malignancy, and complete gastrointestinal evaluation should be conducted. Laparoscopic radical surgery can be safely performed in cases in which the liver abscesses are controlled.

In Klebsiella pneumoniae liver abscess (KP-LA), K. pneumoniae K2 is the most frequently isolated serotype after K1, but this serotype has been much less studied. In the present study, the molecular types sequences type (MLST) of serotype K2 isolates from three different regions in Asia were identified and the virulence of these isolates was investigated. Eight different MLSTs were found among 26 isolates (ST 65, 66, 86, 373, 374, 375, 380, and 434). There were two major MLST groups, ST-65-like (42%) and ST86-like (46%). No isolates contained allS while all isolates contained rmpA. The prevalence of aerobactin gene and kfu were 25/26 (96%) and 3/26 (11.5%) respectively. Although liver abscess isolates were generally more resistant (11/15 isolates) to serum killing, there was no specific distribution of serum killing resistant or susceptible ST types between stool carriage and liver abscess isolates. Neutrophil phagocytosis showed that the liver abscess and carriage isolates varied in their susceptibility to phagocytosis. Strains with resistance to both neutrophil phagocytosis and serum killing were generally hypervirulent with lethality at LD50 < 10(3) colony forming units by intraperitoneal injection. In conclusion, Anti-phagocytosis and resistance to serum killing are two parameters that most predict hyperviurlence in serotype K2 isolates. Unlike serotype K1 KP-LA that mainly belong to ST-23, ST-65-like and -86-like are the two major MLST types among serotype K2 isolates from Singapore, Hong Kong and Taiwan.

A 36-year-old man was referred to the general medical team with endophthalmitis. He was noted to have raised inflammatory markers and deranged liver function tests on admission. Subsequent abdominal ultrasound scan revealed a liver abscess requiring percutaneous drainage. A common human pathogen, Klebsiella pneumoniae, was cultured from multiple sites. K pneumoniae has virulent serotypes (K1 and K2) that can cause primary liver abscess with metastatic infections. Cases have previously been predominantly reported in Southeast Asia but are increasing in prevalence in Europe and North America. The main known risk factor for the disease is diabetes mellitus. Swift antibiotic therapy, ophthalmology review and percutaneous drainage of any liver abscess are essential. Early recognition of the syndrome, despite potentially few initial symptoms, can significantly reduce morbidity and mortality. The authors report the first recorded case of K pneumoniae liver abscess with endophthalmitis in the UK. PMID:23559652

We designed a population-based retrospective cohort study to investigate the association between the event of alcohol intoxication and the risk of pyogenic liver abscess. The present study enrolled 245,076 patients with a history of alcohol intoxication from 2000 to 2010 and matched each of them with four comparison patients, with similar mean age and sex ratios. We determined the cumulative incidences and adjusted hazard ratios (aHRs) of liver abscess. A significant association was observed between alcohol intoxication and liver abscess. The incidence density rate of liver abscess was 3.47-fold greater in the alcohol intoxication (AI) cohort than in the non-AI cohort (12.2 vs. 3.43 per 10,000 person-years), with an adjusted HR (aHR) of 2.64 (95% CI = 2.26 to 3.08). This population-based study positively associated the event of alcohol intoxication with increased risk of liver abscess. Our findings warrant further large-scale and in-depth investigations in this area. Copyright © 2017 Elsevier Inc. All rights reserved.

Pyogenic liver abscess has become a health problem in Taiwanese society. However, the extent of this problem has remained unclear because of the lack of a population-based study. We therefore performed a nationwide analysis of pyogenic liver abscess in Taiwan from 1996 through 2004. We analyzed 29,703 cases from the Taiwan National Health Insurance database and 506 cases from National Taiwan University Hospital. Our analysis showed that the annual incidence of pyogenic liver abscess increased steadily from 11.15/100,000 population in 1996 to 17.59/100,000 in 2004. Diabetes, malignancy, renal disease, and pneumonia were associated with a higher risk for the disease. By contrast, death due to pyogenic liver abscess decreased over time, although population-based abscess-related death increased slightly. Renal disease, malignancy, pneumonia, and heart disease correlated with higher death rates; Klebsiella pneumoniae infection and therapeutic procedures were related to lower death rates. Diabetes did not significantly change death rates for the 506 patients from the hospital. PMID:18826824

Cryptogenic liver abscess (CLA) is a well-known disease entity that has puzzled clinicians for centuries. With the advancement of diagnostic modalities, comes the decreasing incidence of liver abscess labelled as ‘cryptogenic’ in nature. Colonic diseases have been identified as a possible underlying condition found in patients with liver abscesses. Although rare, tubullovillous adenomas have been implicated as one of the colonic causes of a CLA. We present a case of a CLA in a 53-year-old man with a potentially associated tubullovillous adenoma found via colonoscopy. PMID:22778477

Tuberculous liver abscesses are rare. Paradoxical response in tuberculosis is common and occurred between 2 weeks and 12 weeks after anti-tuberculous medication. We report here a case of tuberculous liver abscess that developed in a paradoxical response during chemotherapy for tuberculous peritonitis in a 23-year-old male. He was hospitalized, complaining of ascites, epigastric pain. He was diagnosed tuberculous peritonitis by expiratory laparoscopic biopsy and took medication for tuberculosis. After 2 months, a hepatic lesion was detected with CT scan incidentally. Chronic granulomatous inflammation was seen in ultrasound-guided liver biopsy, and tuberculous liver abscess was diagnosed. It was considered as paradoxical response, rather than treatment failure or other else because clinical symptoms of peritoneal tuberculosis and CT scan improved. After continuing initial anti-tuberculous medication, he was successfully treated. Herein, we report a case of tuberculous liver abscess as paradoxical response while treating peritoneal tuberculosis without changing anti-tuberculous treatment regimen.

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

Fusobacteriae are facultative anaerobic gram-negative bacilli which cause a range of invasive infections, amongst which pyogenic liver abscesses are rare. We describe a case of Fusobacterium nucleatum liver abscess and review the relevant literature. A 51-year-old lady presented with a 4-day history of abdominal pain, diarrhoea, fever, rigors, and lethargy. Imaging revealed an abscess which was drained. Cultures of the blood and abscess aspirate grew Fusobacterium nucleatum and Prevotella pleuritidis respectively. She achieved full recovery following treatment. A MEDLINE search was undertaken using free-text and Medical Subject Headings (MeSH), keywords "Fusobacterium" and "Liver abscess". Non-English language reports and cases without confirmed growth of Fusobacterium species were excluded. Additional cases were identified by surveying the references of each report and by using the same keywords in a web-based search. Forty-eight cases were identified, 41 in men. The median age was 42.5, with an interquartile range of 33. F. nucleatum and F. necrophorum were in involved in 22 cases each, and 4 cases were not further speciated. Among cases of F. nucleatum liver abscess, nine were attributed to periodontal disease, four to lower gastrointestinal tract disease, one to Lemierre's Syndrome, and eight were considered cryptogenic. All patients treated made a full recovery. Antimicrobial treatment duration ranged from 2 weeks to 6 months with a median of 6 weeks. Fusobacterium nucleatum is an uncommon cause of liver abscess generally associated with good clinical outcomes with contemporary medical and surgical care.

Papillon-Lefevre syndrome (PLS) is an autosomal recessive disease that is characterized by symmetric palmoplantar keratodermatitis and severe periodontal destruction. Mutations in the cathepsin C gene (CTSC) have recently been detected in PLS. Immune dysregulation, due to a mutation in CTSC, increases the risk of pyogenic infections in PLS patients. A child with PLS is presented here with liver abscesses and peritonitis caused by Rhizopus oryzae. His liver abscess and peritonitis were cured with amphotericin B without surgical care. This is the first case in the literature liver abscess due to Rhizopus oryzae in a child with PLS.

Purpose: To explore the metabolic characterization of host responses to drainage-resistant Klebsiella pneumoniae liver abscesses (DRKPLAs) with serum 1H-nuclear magnetic resonance (NMR) spectroscopy. Materials and Methods: The hospital records of all patients with a diagnosis of a liver abscess between June 2015 and December 2016 were retrieved from an electronic hospital database. Eighty-six patients with Klebsiella pneumoniae ( K. pneumoniae ) liver abscesses who underwent percutaneous drainage were identified. Twenty patients with confirmed DRKPLAs were studied. Moreover, we identified 20 consecutive patients with drainage-sensitive Klebsiella pneumoniae liver abscesses (DSKPLAs) as controls. Serum samples from the two groups were analyzed with 1H NMR spectroscopy. Partial least squares discriminant analysis (PLS-DA) was used to perform 1H NMR metabolic profiling. Metabolites were identified using the Human Metabolome Database, and pathway analysis was performed with MetaboAnalyst 3.0. Results: The PLS-DA test was able to discriminate between the two groups. Five key metabolites that contributed to their discrimination were identified. Glucose, lactate, and 3-hydroxybutyrate were found to be upregulated in DRKPLAs, whereas glutamine and alanine were downregulated compared with the DSKPLAs. Pathway analysis indicated that amino acid metabolisms were significantly different between the DRKPLAs and the DSKPLAs. The D-glutamine and D-glutamate metabolisms exhibited the greatest influences. Conclusions: The five key metabolites identified in our study may be potential targets for guiding novel therapeutics of DRKPLAs and are worthy of additional investigation.

The purpose of the paper was to explore the relationship between herpes zoster and pyogenic liver abscesses in Taiwan. This was a nationwide cohort study. Using the database of the Taiwan National Health Insurance Program, there were 33049 subjects aged 20-84 years who were newly diagnosed with herpes zoster from 1998 to 2010 that were selected for our study, and they were our herpes zoster group. 131707 randomly selected subjects without herpes zoster were our non-herpes zoster group. Both groups were matched by sex, age, other comorbidities, and the index year of their herpes zoster diagnosis. The incidence of pyogenic liver abscesses at the end of 2011 was then estimated. The multivariable Cox proportional hazard regression model was used to estimate the hazard ratio and 95% confidence interval for pyogenic liver abscesses associated with herpes zoster and other comorbidities. The overall incidence rate was 1.38-fold higher in the herpes zoster group than in the non-herpes zoster group (4.47 vs. 3.25 per 10000 person-years, 95% confidence interval 1.32, 1.44). After controlling for potential confounding factors, the adjusted hazard ratio of pyogenic liver abscesses was 1.34 in the herpes zoster group (95% confidence interval 1.05, 1.72) when compared with the non-herpes zoster group. Sex (in this case male), age, presence of biliary stones, chronic kidney diseases, chronic liver diseases, cancers, and diabetes mellitus were also significantly associated with pyogenic liver abscesses. Patients with herpes zoster are associated with an increased hazard of developing pyogenic liver abscesses.

A 43-year-old man was admitted to our hospital with right hypochondriac and epigastric pain. An abdominal radiograph showed a large niveau in the right subphrenic space. An abdominal CT scan demonstrated a large liver abscess (diameter, 13 cm) with gas formation. Klebsiella pneumoniae cells were isolated from the abscess, and the patient was treated with antibiotics and percutaneous drainage. It is very important to treat gas-forming liver abscess immediately, because subsequent bacteremia and septic shock are frequently noted, and the associated mortality rate is high.

Emphysematous liver abscesses are defined as liver abscesses accompanied by gas formation. The fatality rate is extremely high at 27%, necessitating prompt intensive care. The patient was a 69-year-old Japanese man with type 2 diabetes. He visited the emergency outpatient department for fever and general malaise that had been ongoing for 2 weeks. Abdominal computed tomography revealed an abscess 5 cm in diameter accompanied by gas formation in the right hepatic lobe. Markedly impaired glucose tolerance was observed with a blood sugar level of 571 mg/dL and a glycated hemoglobin level of 14.6%. The patient underwent emergency percutaneous abscess drainage, and intensive care was subsequently initiated. Klebsiella pneumoniae was detected in both the abscess cavity and blood cultures. The drain was removed 3 weeks later, and the patient was discharged. Emphysematous liver abscesses are often observed in patients with poorly controlled diabetes, and the fatality rate is extremely high. Fever and malaise occasionally mask life-threatening infections in diabetic patients, necessitating careful examination.

Fusobacteria are anaerobic gram-negative, non-spore forming bacilli found in normal flora of the oral cavity, urogenital tract, and gastrointestinal tract. Fusobacterium nucleatum has been seldom reported as a cause of liver abscess, particularly in immunocompetent hosts. A 55-year-old man with frequent periodontal disease visited our hospital with intermittent fever and headache for 2 months. Abdominal CT scan revealed an 8.2 × 6 cm mass in the right hepatic lobe with central low density. Abscess culture revealed F. nucleatum as the causative organism. Percutaneous abscess drainage and intravenous administration of antibiotics for 4 weeks improved symptoms and decreased the abscess size. We report a rare case of liver abscess due to F. nucleatum in an immunocompetent man with periodontal disease.

Introduction Prior enterobiliary manipulation confers a high risk for liver abscess formation after hepatic ablation. We aimed to determine if prophylactic antibiotics could prevent post-ablation abscess in patients with a history of hepaticojejunostomy. Materials and Methods This single-institution retrospective study identified 262 patients who underwent 307 percutaneous liver ablation sessions between January 2010 and August 2014. Twelve (4.6%) patients with prior hepaticojejunostomy were included in this analysis. Ten (83>%) had received an aggressive prophylactic antibiotic regimen consisting of levofloxacin, metronidazole, neomycin, and erythromycin base. Two (16.6%) had received other antibiotic regimens. Clinical, laboratory, and imaging findings were used to identify abscess formation and antibiotic-related side effects. Results Twelve ablation sessions were performed during the period studied. During a mean follow-up period of 440 days (range, 77–1784 days), post-ablation abscesses had developed in 2 (16.6 %) patients, who both received the alternative antibiotic regimens. None of the 10 patients who received the aggressive prophylactic antibiotic regimen developed liver abscess. One of the 10 patients who received the aggressive prophylactic antibiotic regimen developed grade 2 antibiotic-related diarrhea and arthralgia. Conclusion An aggressive regimen of prophylactic antibiotics may be effective in preventing liver abscess formation after liver ablation in patients with prior hepaticojejunostomy. PMID:26984694

2013-07-17

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.

The article studies the traits of diagnosis and treatment of 134 patients with amebic affections of liver. It is indicated that on the basis of clinical data it is possible to detect the development of amebic hepatitis or amebic abscess of liver. The most effective methods for treatment are: in case of amebic hepatitis--trans-umbilical injection of amebocytes; in case of amebic abscess of liver--percutaneous puncture of abscess under the ultrasonic sensor control, active aspiration of the content, cavity washing with antiamebic solutions and its trans-umbilical injections.

A wide clinical spectrum of bacteremic disease caused by Fusobacterium has been presented in this journal. We wish to extend this spectrum by presenting a case of myopericarditis resulting from a liver abscess caused by F. nucleatum. While F. nucleatum plays an important role in periodontal disease, and has been isolated from skin ulcers, liver abscesses, urinary tract infections, and endocarditis, a single case of F. nucleatum-induced pericarditis is documented in the literature.

Klebsiella pneumonia is a well-known human pathogen, and recently, a distinct invasive syndrome caused by K. pneumoniae serotypes K1 and K2 has been recognized in Southeast Asia. This syndrome is characterized by primary liver abscess and extrahepatic complications resulting from bacteremic dissemination. We report the first adult case of primary liver abscess caused by the definite K2 serotyped pathogen, with endogenous endophthalmitis in Japan. A 64-year-old woman was admitted to a nearby hospital for a high fever and diarrhea. She had visual loss of her right eye, renal dysfunction, and thrombocytopenia within 24 h from admission. She was transferred to our institution. On admission, she had no alteration of mental status and normal vital signs; however, she had almost complete ablepsia of the right eye. Laboratory data showed severe inflammation, liver dysfunction, thrombocytopenia, an increased serum creatinine level, and coagulopathy. Computed tomography showed a low density area in the right lobe of the liver. Invasive liver abscess syndrome probably caused by K. pneumonia was highly suspected and immediately administered broad-spectrum antibiotics for severe sepsis. Concurrently, endogenous endophthalmitis was diagnosed, and we performed vitrectomy on the day of admission. The blood culture showed K. pneumoniae infection. Percutaneous drainage of the liver abscess was also performed. Although she was discharged in a good general condition on day 22, she had complete ablepsia of the right eye. The K2A gene was detected by polymerase chain reaction (PCR), which is consistent with the K2 serotype. PCR was also positive for the virulence-associated gene rmpA. Final diagnosis was invasive liver abscess syndrome caused by K2 serotype K. pneumonia. Although the primary liver abscess caused by K. pneumoniae with a hypermucoviscous phenotype is infrequently reported outside Southeast Asia, physicians should recognize this syndrome, and appropriate diagnosis and treatment is essential for saving patients' lives and preserving organ function, especially for visual acuity.

The emergence of a new hypervirulent variant of Klebsiella pneumoniae, which can cause serious infections in the Asian population, is under investigation. We report a case series of six Asian patients hospitalized at our institution from January 2013 to November 2015 for liver abscess due to Klebsiella pneumoniae. Case Report: Charts of six Asian patients were retrospectively reviewed. Four patients were male and two were female. The mean age was 53 years (range: 35–64 years). All patients had no known past medical history of immunodeficiency. Three patients had multiple liver abscesses at the time of initial presentation. In five patients, the source of entry of the pathogenic microorganism was unknown and in one patient the suspected source of entry was the gastrointestinal tract. In three patients there was also concomitant Klebsiella pneumoniae bacteremia. The mean duration of antibiotic treatment was seven weeks and the mean duration of hospital stay was 13.5 days. Conclusions: Liver abscess should always be included in the differential diagnosis in cases of sepsis without obvious source and/or in the clinical scenarios of fever, abdominal pain, and liver lesions.

In Thailand, the burden of liver abscess, a life-threatening infectious disease, has not been thoroughly evaluated. We developed a predictive scoring system to estimate survival of patients with liver abscess using information from the 2008–2013 Nationwide Hospital Admission Data to evaluate the burden of liver abscess in Thailand. All patients with primary diagnosis of pyogenic liver abscess (PLA) and amoebic liver abscess (ALA) were included. Epidemiological data, baseline characteristics, hospital course, and survival were analyzed. Overall, 11,296 admissions comprising 8,423 patients from 844 hospitals across Thailand were eligible for analysis. The mean age was 52 ± 17 years and 66.1% of patients were male. ALA was significantly prevalent in southern and western border regions of Thailand, and PLA occurred nationwide. The highest incidence of liver abscess occurred in the rainy season (June–November, P < 0.01). The median length of hospital stay was 8 days (interquartile range = 4–13 days), and mean direct cost of hospitalization was 846 ± 1,574 USD. The overall inhospital mortality rate was 2.8%. Incidence of ALA decreased over the 5-year study period, whereas PLA incidence increased (P < 0.01). Using multivariable Cox regression methods with stepwise variable selection, we developed a final model with five highly significant baseline parameters associated with increased 60-day mortality: older age, PLA, underlying chronic kidney disease, cirrhosis, and human immunodeficiency virus infection. Range of estimated probability of 60-day survival was 95–16% at cumulative risk score 0–13. This simplified score is practical, and may help clinicians prioritize patients requiring more intensive care. PMID:27325801

PurposeThis study was performed to evaluate the accumulation of lipiodol emulsion (LE) and adverse events during our initial experience of balloon-occluded trans-catheter arterial chemoembolization (B-TACE) for hepatocellular carcinoma (HCC) compared with conventional TACE (C-TACE).MethodsB-TACE group (50 cases) was compared with C-TACE group (50 cases). The ratio of the LE concentration in the tumor to that in the surrounding embolized liver parenchyma (LE ratio) was calculated after each treatment. Adverse events were evaluated according to the Common Terminology Criteria for Adverse Effects (CTCAE) version 4.0.ResultsThe LE ratio at the level of subsegmental showed a statistically significant difference between the groups (tmore » test: P < 0.05). Only elevation of alanine aminotransferase was more frequent in the B-TACE group, showing a statistically significant difference (Mann–Whitney test: P < 0.05). While B-TACE caused severe adverse events (liver abscess and infarction) in patients with bile duct dilatation, there was no statistically significant difference in incidence between the groups. Multivariate logistic regression analysis suggested that the significant risk factor for liver abscess/infarction was bile duct dilatation (P < 0.05).ConclusionThe LE ratio at the level of subsegmental showed a statistically significant difference between the groups (t test: P < 0.05). B-TACE caused severe adverse events (liver abscess and infarction) in patients with bile duct dilatation.« less

Neonatal liver abscess is an uncommon seen condition in neonatology and it holds a very high neonatal mortality because of difficulty in diagnosis and treatment. Till today, only few instances are reported that too are mainly in preterm. Its diagnosis requires a high index of suspicion. Fungal hepatic abscess is very rare and in medical literature very few case reports are there in the medical literature. Here, we report a case of Candida albicans liver abscess in a preterm neonate, secondary to malpositioned umbilical lines that presented with respiratory difficulty and other clinical features of sepsis that was managed medically and discharged successfully.

Amebiasis still remains as a major public health problem in the world. It is one of the most common reasons for medical consult. There are more than half a million cases of amebiasis just at the Mexican Institute of the Social Security. There is still a lack of epidemiologic information on amebiasis in Mexico. To describe the secular trend fro amebiasis and for amebic liver abscess in the Mexican population, as well as in those covered by IMSS Solidaridad. An ecologic trend study was carried on. Incidence rate of amebiasis in all of its forms of presentation, and of amebic liver abscess, were plotted against each year for the 1986-1994 period. Amebiasis incidence in all of its forms of presentation showed a stable trend in this period, as it was seen with amebic liver abscess. Amebiasis is more common in the first years of life. On the contrary, amebic liver abscess showed an inverted 'J' pattern; its occurrence is higher in the extreme years of life. Fatality rates have shown a descendent trend. Amebiasis reflects socioeconomic conditions in Mexico and the fact that Mexican is still an endless culture. There is a need to promote health education, better diagnostic procedures and detection of asymptomatic carriers. Health policies for mothers that are asymptomatic carriers should be reviewed, due to the high rates of amebiasis and amebic liver abscess in children under one year of age.

Initial presentations and final outcomes of primary pyogenic liver abscess: a cross-sectional study

2014-01-01

Background Although pyogenic liver abscess (PPLA) fatalities are decreasing owing to early diagnosis and effective treatments, PPLA-associated complications still exist. The purpose of this study was to analyze the characteristic features of initial presentations and final outcomes of PPLA caused by different pathogens. Methods This retrospective study collected and analyzed information regarding initial presentations and final outcomes in patients diagnosed with PPLA at admitted at Changhua Christian Hospital from January 1 to December 31, 2010. Results During the study period, we analyzed the records of a total of 134 patients with documented PPLA. There were no significant causative pathogen-related differences in symptoms at initial presentation. Compared with the survivor group, patients in the mortality group were characterized by male gender (p < 0.001), malignancy (p < 0.001), respiratory distress (p =0.007), low blood pressure (p = 0.024), jaundice (p = < 0.001), rupture of liver abscess (p < 0.001), endophthalmitis (p = 0.003), and multiple organ failure (p < 0.001). No patients received liver transplantation or were diagnosed with HIV during the study period. According to univariate logistic regression analysis, gender (OR = 1.185, 95% CI: 0.284–11.130, p = 0.006), malignancy (OR = 2.067, 95% CI: 1.174–13.130, p = 0.004), respiratory distress (OR = 1.667, 95% CI: 1.164–14.210, p = 0.006), low blood pressure (OR = 2.167, 95% CI: 2.104–13.150, p = 0.003), jaundice (OR = 1.9, 95% CI: 1.246–3.297, p = 0.008), rupture of liver abscess (OR = 5.167, 95% CI: 2.194–23.150, p = 0.003), endophthalmitis (OR = 2.167, 95% CI: 1.234–13.140, p = 0.005), and multiple organ failure (OR = 3.067, 95% CI: 1.184–15.150, p = 0.001) differed significantly between the mortality and survivor groups. Conclusion Although the initial presentations of PPLA caused by different pathogens were similar, there were significant differences in mortality in cases involving: (1) male patients, (2) malignancy, (3) initial respiratory distress, (4) initial low blood pressure, (5) jaundice, (6) rupture of liver abscess, (7) endophthalmitis, , and (8) multiple organ failure. We strongly recommend using a severity score of the disease to determine the risk of mortality for each patient with PPLA. In order to prevent complications and reduce mortality, more attention must be paid to high-risk PPLA patients. PMID:25066384

The virulence role of surface antigens in a single serotype of Klebsiella pneumoniae strain have been studied, but little is known about whether their contribution will vary with serotype. To investigate the role of K and O antigen in hyper-virulent strains, we constructed O and K antigen deficient mutants from serotype K1 STL43 and K2 TSGH strains from patients with liver abscess, and characterized their virulence in according to the abscess formation and resistance to neutrophil phagocytosis, serum, and bacterial clearance in liver. Both of K1 and K2-antigen mutants lost their wildtype resistance to neutrophil phagocytosis and hepatic clearance, and failed to cause abscess formation. K2-antigen mutant became serum susceptible while K1-antigen mutant maintained its resistance to serum killing. The amount of glucuronic acid, indicating the amount of capsular polysaccharide (CPS, K antigen), was inversed proportional to the rate of phagocytosis. O-antigen mutant of serotype K1 strains had significantly more amount of CPS, and more resistant to neutrophil phagocytosis than its wildtype counterpart. O-antigen mutants of serotype K1 and K2 strains lost their wildtype serum resistance, and kept resistant to neutrophil phagocytosis. While both mutants lacked the same O1 antigen, O-antigen mutant of serotype K1 became susceptible to liver clearance and cause mild abscess formation, but its serotype K2 counterpart maintained these wildtype virulence. We conclude that the contribution of surface antigens to virulence of K. pneumoniae strains varies with serotypes.

Diabetes mellitus is an important risk factor for Klebsiella pneumoniae liver abscess, but many patients with pyogenic liver abscess (PLA) do not have diabetes. This study was conducted to compare the clinical characteristics and prognostic factors of K. pneumoniae PLA with that caused by other organisms in non-diabetic patients. The medical charts of patients with a diagnosis of PLA were retrospectively reviewed from January 2005 to December 2007. The clinical symptoms and signs, laboratory data, and risk factors were analyzed. There were 50 patients in the K. pneumoniae group and 34 patients in the non-K. pneumoniae group. The clinical presentations did not differ between the 2 groups. The patients in the non-K. pneumoniae group had a higher prevalence of malignant disease than those in the K. pneumoniae group (58.8% vs 6.0%; p < 0.001). Non-K. pneumoniae PLA was strongly associated with hepatobiliary tumor (p = 0.015). Among the non-K. pneumoniae isolates, Escherichia coli was the most common pathogen (n = 20; 58.8%). Forty seven K. pneumoniae isolates (94%) were susceptible to all tested antimicrobial agents except ampicillin, while the non-K. pneumoniae Gram-negative pathogens had greater resistance to first-generation cephalosporins. Poor prognostic factors included chronic renal failure (p = 0.005), abscess rupture (p = 0.036), and right lower lung infiltration (p = 0.049). Hepatobiliary malignancy and newly diagnosed malignancy were risk factors for non-K. pneumoniae liver abscess in non-diabetic patients. Physicians should ascertain the presence of underlying malignancy in patients with non-K. pneumoniae PLA.

Monomicrobial Klebsiella pneumoniae Necrotizing Fasciitis With Liver Abscess: A Case Report and Literature Review.

Necrotizing fasciitis is one of the most life-threatening soft tissue infections and usually follows a major or minor trauma. Published reports regarding single microorganism liver abscess caused by Klebsiella pneumoniae in Taiwan indicate a septic metastasis rate about 12%. Although a hematogenous origin of necrotizing fasciitis from a liver abscess is rare in Taiwan, it remains possible in our clinical practice. A 75-year-old man with a history of diabetes and liver abscess had a status of postdrainage 5 years earlier. The patient presented with elevated body temperature, swelling, and pain over the left hand and forearm for 4 days before coming to our emergency room. We performed a fasciotomy procedure under the preliminary diagnosis of necrotizing fasciitis. The patient's blood cultures yielded K. pneumoniae, and therefore recurrence of liver abscess was confirmed by ultrasonography. After treating with percutaneous drainage and third cephalosporin intravenously, the patient recovered and discharged on the 50th day after admission. Necrotizing fasciitis is a life-threatening soft tissue infectious disease. Once K. pneumoniae is identified both in blood and wound cultures of a diabetic patient with necrotizing fasciitis, it is recommended that the metastatic lesions undergo complete abdominal evaluation by the hematogenous route.

Background Worldwide, amoebic liver abscess (ALA) can be found in individuals in non-endemic areas, especially in foreign-born travelers. Methods We performed a retrospective analysis of ALA in patients admitted to French hospitals between 2002 and 2006. We compared imported ALA cases in European and foreign-born patients and assessed the factors associated with abscess size using a logistic regression model. Results We investigated 90 ALA cases. Patient median age was 41. The male:female ratio was 3.5∶1. We were able to determine the origin for 75 patients: 38 were European-born and 37 foreign-born. With respect to clinical characteristics, no significant difference was observed between European and foreign-born patients except a longer lag time between the return to France after traveling abroad and the onset of symptoms for foreign-born. Factors associated with an abscess size of more than 69 mm were being male (OR = 11.25, p<0.01), aged more than 41 years old (OR = 3.63, p = 0.02) and being an immigrant (OR = 11.56, p = 0.03). Percutaneous aspiration was not based on initial abscess size but was carried out significantly more often on patients who were admitted to surgical units (OR = 10, p<0.01). The median time to abscess disappearance for 24 ALA was 7.5 months. Conclusions/Significance In this study on imported ALA was one of the largest worldwide in terms of the number of cases included males, older patients and foreign-born patients presented with larger abscesses, suggesting that hormonal and immunological factors may be involved in ALA physiopathology. The long lag time before developing ALA after returning to a non-endemic area must be highlighted to clinicians so that they will consider Entamoeba histolytica as a possible pathogen of liver abscesses more often.

We report a case of a 16-year-old female patient with sickle-cell disease with a liver abscess secondary to methicillin-resistant Staphylococcus aureus (MRSA). She had initially presented with jaundice and abdominal pain and subsequently underwent endoscopic retrograde cholangio-pancreaticography followed by laparoscopic cholecystectomy for removal of gallstones. However, post-cholecystectomy she presented with generalized abdominal pain and computed tomography scan of the abdomen revealed a liver abscess. A pigtail catheter was inserted into the abscess and culture of the aspirate yielded MRSA (susceptibility pattern of the organism was compatible with community-acquired MRSA). She was treated with intravenous clindamycin for 6 weeks with complete resolution of the abscess.

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.

A 72-year-old woman with diabetes mellitus was admitted with fever and general fatigue. Blood biochemistry showed elevated hepatic and biliary enzyme levels, abdominal computed tomography showed multiple liver abscesses with portal and superior mesenteric vein thrombosis, and total colonoscopy revealed a submucosal bacterial abscess in the ascending colon. The abscesses were determined to be associated with Enterococcus faecalis infection. The patient was treated conservatively with antibiotics (meropenem) and anticoagulants (warfarin), which led to a gradual amelioration of symptoms and resolution of thrombosis.

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. 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. 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. 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 conventional molecular methods.

Amebiasis Presenting as Pleuropulmonary Disease

1985-01-01

Seven patients with amebic liver abscess presenting as pleuropulmonary disease were admitted to hospital initially because of pulmonary symptoms and were found to have amebic liver disease. Three categories of pleuropulmonary involvement included reactive inflammation of the pleura or lung, rupture of a hepatic abscess into the pleural space and rupture of a hepatic abscess into the bronchial airways. The preferred medical treatment is with metronidazole, but rupture of hepatic amebic abscess into the pleural space requires drainage in addition to medical therapy. In contrast, rupture into the bronchus may provide spontaneous drainage so that only medical therapy is needed. Recovery from amebiasis in all three categories is generally complete. Morbidity and mortality increase with failure to correctly identify amebic infection of the liver as the underlying cause. Because, in new cases, no findings specifically suggest that pleuropulmonary disease is a complication of hepatic amebic abscess, this possibility needs to be considered, especially in persons who are at risk of having been infected with amebae.

This paper presents liver abscesses, as studied in the ancient Greek and Greco-Roman bibliography. Numerous references concerning this entity can be found in the writings of the Hippocratic doctors (5th cent. B.C.), Archigenes of Apamea (1st cent. A.D.), Galen (2nd cent. A.D.), Aretaeus of Cappadocia (2nd cent. A.D), Oribasius (4th cent. A.D.), Theophilus Protospatharius (7th cent. A.D.), and Paulus Nicaeensis (7th-10th cent. A.D.). In most cases the clinical manifestations, the prognosis and the method of treatment are presented. In all ancient writings we studied, the rupture of a liver abscess is also part of the main theme. In specific, the path that the fluid would follow after a rupture was considered to be a main prognostic factor, i.e. if the fluid "coursed into the stomach", the patient would definitely die. In this work, an attempt is also made to correlate the ancient descriptions to modern medical entities, such as amebic or pyogenic liver abscess.

Purpose To compare the clinical and computed tomography (CT) appearances of liver abscesses caused by non-Klebsiella pneumoniae bacterial pathogens in elderly and nonelderly patients. Materials and Methods Eighty patients with confirmed non-Klebsiella pneumoniae liver abscesses (non-KPLAs) were enrolled and divided into two age groups: elderly (age ≥65 years, n=42) and nonelderly (age <65 years, n=38). Diagnosis of non-KPLA was established by pus and/or blood culture. We compared clinical presentations, outcomes, and CT characteristics of the two groups, and performed multivariate analysis for significant variables and receiver-operating-characteristic analysis to determine the cutoff value of abscess diameter for predicting non-KPLA. Results Elderly patients with non-KPLA were associated with a longer hospital stay (p<0.01). Regarding etiology, biliary sources had a strong association in the elderly group (p<0.01), and chronic liver diseases were related to the nonelderly group (p<0.01). Non-KPLAs (52.5%) tended to show a large, multiloculated appearance in the elderly group and were associated with bile duct dilatation (p<0.01), compared with the nonelderly group. The abscess diameter (cutoff value, 5.2 cm; area under the curve, 0.78) between the two groups was predicted. In multivariate analysis, underlying biliary tract disease [odds ratio (OR), 3.58, p<0.05], abscess diameter (OR, 2.40, p<0.05), and multiloculated abscess (OR, 1.19, p<0.01) independently predicted elderly patients with non-KPLA. Conclusion In the elderly patients with non-KPLA, a large, multiloculated abscess with a diameter greater than 5.2 cm was the predominant imaging feature. PMID:25684004

We studied 13 emergency cases of liver abscess. Five cases of septic shock or clouding of consciousness were identified on admission. Six patients had diabetes mellitus. Twelve patients met the diagnostic criteria for systemic inflammatory response syndrome, and nine met the criteria for disseminated intravascular coagulation. Plasma endotoxin levels improved rapidly after drainage. Causative organisms were isolated in all patients, and the most common organism was Klebsiella pneumoniae (seven cases). Percutaneous transhepatic abscess drainage (PTAD) was performed not only in single cases but also in multiple cases with main huge abscesses. Surgical treatment was performed in the following three cases: a ruptured abscess, an ineffective PTAD, and a case of peritonitis after PTAD. Irrigation of abscesses with strong acidic electrolyzed water revealed a significant decrease in treatment duration. In the majority of our cases, severe conditions were identified on admission. Strong acidic electrolyzed water was useful for management of PTAD.

The protozoan parasite Entamoeba histolytica is the causative agent of amoebiasis, a human disease characterized by dysentery and liver abscess. The physiopathology of hepatic lesions can be satisfactorily reproduced in the hamster animal model by the administration of trophozoites through the portal vein route. Hamsters were infected with radioactively labeled amoebas for analysis of liver abscess establishment and progression. The radioimaging of material from parasite origin and quantification of the number inflammation foci, with or without amoebas, described here provides the first detailed assessment of trophozoite survival and death during liver infection by E. histolytica. The massive death of trophozoites observed in the first hours postinfection correlates with the presence of a majority of inflammatory foci without parasites. A critical point for success of infection is reached after 12 h when the lowest number of trophozoites is observed. The process then enters a commitment phase during which parasites multiply and the size of the infection foci increases fast. The liver shows extensive areas of dead hepatocytes that are surrounded by a peripheral layer of parasites facing inflammatory cells leading to acute inflammation. Our results show that the host response promotes massive parasite death but also suggest also that this is a major contributor to the establishment of inflammation during development of liver abscess.

A 63-year-old woman presented with fever, tachycardia and tachypnoea, with right sided chest and hypochondrial pain. Chest radiograph showed right basal consolidation and she was treated for community acquired pneumonia with intravenous antibiotics. Subsequent clinical deterioration in presence of a previous history of complicated diverticulitis, persistent right hypochondrial pain and deranged liver function tests prompted further investigations that confirmed presence of a large pyogenic liver abscess. Following appropriate antibiotic treatment and image guided drainage of the abscess, the patient made a complete recovery. This case illustrates the importance of considering a subdiaphragmatic source of sepsis even in the presence of chest radiographic abnormalities, when a patient fails to respond to initial treatment for pneumonia.

Ultrasound examinations were done to evaluate clinically palpable abdominal masses in 125 children. The examinations were normal in 21 patients. In 15 patients, the clinically palpable masses were actually anterior abdominal wall abscesses or hematomas. Final diagnosis was available in 87 of 89 patients with intraabdominal masses detected on ultrasound. The majority (71%) were retroperitoneal masses where two-thirds were of renal origin. Ultrasound diagnosis was correct in 68 patients (78%). All cases of hydronephrosis were correctly diagnosed based on characteristic ultrasound appearances. Correct diagnoses of all cases of adrenal hematoma, psoas abscess, liver hematoma, liver abscess and one case of liver metastases were achieved with correlation of relevant clinical information.

Klebsiella pneumoniae liver abscess is the most common etiology of liver abscess in Singapore and much of Asia, and its incidence is increasing. Current management includes prolonged intravenous antibiotic therapy, but there is limited evidence to guide oral conversion. The implicated K1/K2 capsule strain of Klebsiella pneumoniae is almost universally susceptible to ciprofloxacin, an antibiotic with high oral bioavailability. Our primary aim is to compare the efficacy of early (< one week) step-down to oral antibiotics, to continuing four weeks of intravenous antibiotics, in patients with Klebsiella liver abscess. The study is designed as a multi-center randomized open-label active comparator-controlled non-inferiority trial, with a non-inferiority margin of 12%. Eligible participants will be inpatients over the age of 21 with a CT or ultrasound scan suggestive of a liver abscess, and Klebsiella pneumoniae isolated from abscess fluid or blood. Randomization into intervention or active control arms will be performed with a 1:1 allocation ratio. Participants randomized to active control will receive IV ceftriaxone 2 grams daily to complete a total of four weeks of IV antibiotics. Participants randomized to intervention will be immediately converted to oral ciprofloxacin 750 mg twice daily. At Week four, all participants will undergo abdominal imaging and be assessed for clinical response (CRP < 20 mg/l, absence of fever, plus scan showing that the maximal diameter of the abscess has reduced). If criteria are met, antibiotics are stopped; if not, oral antibiotics are continued, with reassessment for clinical response fortnightly. If criteria for clinical response are met by Week 12, the primary endpoint of clinical cure is met. A cost analysis will be performed to assess the cost saving of early conversion to oral antibiotics, and a quality of life analysis will be performed to assess whether treatment with oral antibiotics is less burdensome than prolonged IV antibiotics. Our results would help inform local and international practice guidelines regarding the optimal antibiotic management of Klebsiella liver abscess. A finding of non-inferiority may translate to the wider adoption of a more cost-effective strategy that reduces hospital length of stay and improves patient-centered outcomes and satisfaction.

Since 1985, amoebic liver abscess (ALA) has been a public health problem in northern Sri Lanka. Clinicians arrive at a diagnosis based on clinical and ultrasonographic findings, which cannot differentiate pyogenic liver abscess (PLA) from ALA. As the treatment and outcome of the ALA and PLA differs, determining the etiological agent is crucial. All clinically diagnosed ALA patients admitted to the Teaching Hospital (TH) in Jaffna during the study period were included and the clinical features, haematological parameters, and ultrasound scanning findings were obtained. Aspirated pus, blood, and faecal samples from patients were also collected. Pus and faeces were examined microscopically for amoebae. Pus was cultured in Robinson's medium for amoebae, and MacConkey and blood agar for bacterial growth. ELISA kits were used for immunodiagnosis of Entamoeba histolytica infection. DNA was extracted from selected pus samples and amplified using nested PCR and the purified product was sequenced. From July 2012 to July 2015, 346 of 367 clinically diagnosed ALA patients admitted to Jaffna Teaching Hospital were enrolled in this study. Almost all patients (98.6%) were males with a history of heavy alcohol consumption (100%). The main clinical features were fever (100%), right hypochodric pain (100%), tender hepatomegaly (90%) and intercostal tenderness (60%). Most patients had leukocytosis (86.7%), elevated ESR (85.8%) and elevated alkaline phosphatase (72.3%). Most of the abscesses were in the right lobe (85.3%) and solitary (76.3%) in nature. Among the 221 (63.87%) drained abscesses, 93.2% were chocolate brown in colour with the mean volume of 41.22 ± 1.16 ml. Only four pus samples (2%) were positive for amoeba by culture and the rest of the pus and faecal samples were negative microscopically and by culture. Furthermore, all pus samples were negative for bacterial growth. Antibody against E. histolytica (99.7%) and the E. histolytica antigen were detected in the pus samples (100%). Moreover, PCR and sequencing confirmed these results. To our knowledge, this is the first report from Sri Lanka that provides immunological and molecular confirmation that Entamoeba histolytica is a common cause of liver abscesses in the region.

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 conventional molecular methods. PMID:26997014

Liver cysts are divided into congenital and acquired. Congenital cystic lesions include polycystic liver disease, simple cysts, duct related and ciliated hepatic foregut cysts. Acquired cystic lesions are divided into infectious and non-infectious. The infectious cysts are the hydatid cyst, the amoebic abscess, and the pyogenic abscess, whereas the non-infectious cysts are neoplastic cysts and false cysts. While modern medicine provides a lot of minimally invasive therapeutic modalities, there has emerged a pressing need for understanding the various types of liver cysts, the possible minimal therapeutic options along with their indications and complications. We aim is to clarify the role of minimally invasive techniques in the management of hepatic cysts. A literature review was performed using the MEDLINE database. The search terms were: liver cyst, minimally invasive, laparoscopic, percutaneous, drainage and fenestration. We reviewed 82 English language publications articles, published until October 2017. Minimally invasive management of liver LC is an emerging field including many therapeutic modalities ranging from the percutaneous aspiration of pyogenic abscesses to laparoscopic hepatectomy for hepatic cystadenomas. The most used techniques are percutaneous drainage, laparoscopic fenestration, and laparoscopic hepatectomy. The application of the various minimally invasive approaches, as well as their indication and complications, depend on the type of the cystic lesion, its size and its position in the liver. Percutaneous drainage is mostly used in simple cysts, hydatid cysts, pyogenic abscesses and bilomas. Laparoscopic fenestration is mostly used in simple cysts and polycystic liver disease. Finally, laparoscopic hepatectomy is mostly used in polycystic liver disease, hydatid cysts, and cystadenomas.

We studied prospectively all cases of suspected liver abscesses admitted to our unit over 2 years (1990 & 1991). A special case sheet was prepared. Daily follow up of patients was carried out in hospital for at least 10 days. Patients were later followed up by ultrasound after discharge. We compared the rate of infection from the hospital records over the last 9 years up to the end of 1998. We found the clinical features of the disease similar to those mentioned in essential text books of medicine, except that pain is not always epigastric while fever may be absent and hepatomegaly is not marked. Ultrasound is a simple, cheap diagnostic test, which is available. Metronidazole is an effective treatment and none of the patients required an invasive method for diagnosis or treatment. None had secondary bacterial infection. Amoebic liver abscess if untreated is a grave disorder. We concluded that recognizing the disorder clinically and proving it by ultrasound is the main method for diagnostic confirmation. Following the hospital records of the last 9 years, it seems that the rate of infection is declining in this area.

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 accordingmore » 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.« less

AIM: To elaborate the clinicopathologic features of colorectal cancer-related pyogenic liver abscess (PLA). METHODS: Reported cases of colorectal cancer-related PLAs were collected from the literature published up to October 2011 and evaluated for their clinicopathologic features. Data of collected cases included demographics, clinical presentation, microbial findings and treatment. Categorical variables were compared by χ2 analysis and continuous variables were evaluated using Student’s t test. RESULTS: A total 96 cases of colorectal cancer-related PLA were collected from the previous literature. Most patients (60%) were male and 40% cases occurred in the age group of 61-70 years. Apart from some special types of PLA, there were significant differences in the microbiological spectrum between Eastern Asia and non-Eastern Asian countries, which implied different risk factors and courses of the disease. Gram negative bacteria especially Klebsiella pneumoniae (K. pneumoniae) PLA was predominant in Eastern Asia (80.0%) in contrast to non-Eastern Asian countries (P < 0.01). Meanwhile, most of the Eastern Asian patients exhibited smaller size of liver abscess and atypical presentation. Sigmoid colon and rectum (72.73%) were the main sites of tumor in Eastern Asian patients, whereas tumor sites were uneven among most of the non-Easter Asian PLA patients. CONCLUSION: K. pneumoniae PLA was strongly associated with colorectal cancer, especially those occurring in sigmoid colon and rectum, in elderly Eastern Asian male patients. PMID:22736918

Pyogenic liver abscess (PLA) is a rare pediatric disease. Typically, PLA is found in adults with biliary disease. There are no typical physical findings or symptoms. Often, pathogenic organisms are not recovered for identification. This case illustrates a teenager presenting with prolonged episodes of fever and vomiting. With percutaneous drainage and month-long antibiotic therapy, the PLA resolved. This case illustrates that a high index of suspicion is needed for diagnosis.

OBJECTIVES: Septic pulmonary embolism caused by a Klebsiella (K.) pneumoniae liver abscess is rare but can cause considerable morbidity and mortality. However, clinical information regarding this condition is limited. This study was conducted to elucidate the full disease spectrum to improve its diagnosis and treatment. METHOD: We reviewed the clinical characteristics, imaging findings, and clinical courses of 14 patients diagnosed with septic pulmonary embolism caused by a K. pneumoniae liver abscess over a period of 9 years. RESULTS: The two most prevalent symptoms were fever and shortness of breath. Computed tomography findings included a feeding vessel sign (79%), nodules with or without cavities (79%), pleural effusions (71%), peripheral wedge-shaped opacities (64%), patchy ground-glass opacities (50%), air bronchograms within a nodule (36%), consolidations (21%), halo signs (14%), and lung abscesses (14%). Nine (64%) of the patients developed severe complications and required intensive care. According to follow-up chest radiography, the infiltrates and consolidations were resolved within two weeks, and the nodular opacities were resolved within one month. Two (14%) patients died of septic shock; one patient had metastatic meningitis, and the other had metastatic pericarditis. CONCLUSION: The clinical presentations ranged from insidious illness with fever and respiratory symptoms to respiratory failure and septic shock. A broad spectrum of imaging findings, ranging from nodules to multiple consolidations, was detected. Septic pulmonary embolism caused by a K. pneumoniae liver abscess combined with the metastatic infection of other vital organs confers a poor prognosis. PMID:26106957

Amebic liver abscesses (ALA) are not commonly described in travelers. The ALA diagnosis is usually based on serology and Entamoeba histolytica polymerase chain reaction (PCR) is a new tool. We retrospectively reviewed all ALA cases diagnosed by PCR on the liver abscess pus aspirate of patients admitted in French hospitals between 2007 and 2011. Fourteen cases (10 male, median age 48 years) were included. The median lag time between return and onset of symptoms was 23 days (interquartile range [IQ] 18–24). All patients had an elevated cardiopulmonary resuscitation level, and 11 had leukocytosis. The ALA was multiple in five patients, localized in the right lobe in 12, and higher than 5 cm in 11. Serology was initially negative in one patient, whereas PCR was positive. There was bacterial co-infection in one patient. The outcome was good. Liver puncture allows a rapid diagnosis of ALA with PCR and helps identify the association with a bacterial dual infection. PMID:23033402

Lesions of the segmental and lobar hepatic ducts.

Despite reports to the contrary, unobstructed drainage of 50% of an otherwise normal liver through either the right or left uninfected hepatic duct is adequate to restore normal liver function, even if the obstructed lobe remains in place. An undrained liver lobe, if present, may require no further treatment. As long as it is completely obstructed and uninfected, it will undergo a progressive asymptomatic atrophy. Cholangitis invariably develops behind a partial lobar ductal obstruction, producing jaundice, pruritis, and fever. Unless unobstructed, uninfected biliary flow can be achieved through a segmental or lobar duct, it is better that the duct be completely obstructed and the affected liver parenchyma allowed to atrophy, provided there is normal biliary flow from the residual 50% of liver. This concept is important in the management of injured anomalous segmental or lobar hepatic duct and in the palliative treatment of bile duct carcinoma. Localized intrahepatic infections communicating with abnormal biliary ducts will require hepatic resection of the infected parenchyma and ducts for cure. The abnormality may be saccular dilatation of the intrahepatic ductal system with abscess formation or intrahepatic abscess associated with stenosis of the ductal system from trauma to the duct, to the duct and liver, or to retained intrahepatic stones. Diffusely situated intrahepatic abscesses secondary to ductal abnormalities can be treated with systemic antibiotics, local drainage of a dmoninant abscess, and efforts to improve biliary drainage.

Eosinophilic granulomatous gastrointestinal and hepatic abscesses attributable to basidiobolomycosis and fasciolias: a simultaneous emergence in Iraqi Kurdistan

PubMed Central

2013-01-01

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 fluke two years after initial diagnosis. Serological testing for Toxocara and Echinococcus granulosus was negative in all 14 patients. Conclusions Basidiobolomycosis and F. hepatica are implicated as the cause of abdominal eosinophilic granulomatous abscesses in 12 of 14 patients identified over a period of 40 months in northern Iraq. Treatment was complicated by chronic biliary tract disease in fascioliasis and perforation and recurrent intestinal obstruction with basidiobolomycosis. PMID:23421741

An unexplained increase in the frequency of pyogenic liver abscesses of unknown etiology has, fortunately, 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 percent) 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 to 108 F), 100 percent; leucocytosis, 71 percent; anorexia and vomiting, 50 percent; localized tenderness and hepatomegaly, 50 percent; hypoalbuminemia; 86 percent; hypocholesterolemia, 78 percent; elevated SGOT,more » 71 percent; and elevated aikaline phosphatase, 43 percent. Technetium hepatic scintiscans showed focal defects in 10 of 12 patients (83 percent), 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 transthoracic 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 percent) recovered, one dying from pulmonary embolism. Primary hepatic abscesses occur with increasing frequency. The methods described allow more precise preoperative diagnosis and direct surgical drainage. (auth)« less

Wernicke’s encephalopathy associated with liver abscess.

PubMed

Verma, Rajesh; Garg, Vipul

2017-07-31

Wernicke's encephalopathy is a rare neurological disorder caused by thiamine deficiency, characterised by ocular motor dysfunction, ataxia and impairment in consciousness. It predominantly affects brain regions with a high metabolic rate such as mammillary bodies, medial thalamic nuclei, the tectal region and the cerebellum. Although chronic alcoholism is the most common cause of Wernicke's encephalopathy, various other conditions not related to alcohol consumption such as bariatric surgery, acute pancreatitis, hyperemesis gravidarum, prolonged fasting and gastrointestinal surgery have been implicated in its aetiology. We report the case of a patient who underwent surgery for liver abscess and subsequently developed Wernicke's encephalopathy; he showed a positive response to thiamine supplementation. This is the first report describing liver abscess as the cause of Wernicke's encephalopathy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

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.

We herein report two separate cases in which a tuberculous abscess of the chest wall invaded the liver by penetrating through the diaphragm. After confirming the presence of tuberculous lesions in the chest wall and liver, both patients received preoperative anti-tuberculosis (TB) medications for two weeks; after which, the lesions were surgically removed. Following surgery, both patients fully recovered and were asymptomatic, but continued to receive routine postoperative care involving anti-TB medications. Neither patient showed recurrence of TB during a 15-month follow-up period.

This is a metastatic spread of squamous cell lung carcinoma to lungs, liver, lymph node, bone and subcutanous region as multiple abscess-like lesions. A fifty-five years old man admitted to the out-patient clinic with fever, cough, hemopthysis, night sweats, chest pain, abdominal pain and weight loss. In a short period of time abcess like lesions developed in his lungs, liver, lymph node, bone and subcutanous region. Though the clinical presentation is suggestive for an infectious condition, no success to antimicrobial treatment and negative results of microbiological studies have arised a need to further investigations. Histopathological studies of the abscess wall ultimately gave the definitive diagnosis as metastatic squamous cell carcinoma. We believe that case report is interesting because of the uncommon metastatic lesions masquerading the abscesses and also wide-spread multiple distant invasions of a squamous cell lung carcinoma in a short time period.

Melioidosis: A Rare Cause of Liver Abscess

Teh, Catherine S. C.; Casupang, Ma. Amornetta J.

2016-01-01

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

A Klebsiella pneumoniae liver abscess presenting with myasthenia and tea-colored urine

PubMed Central

Deng, Lihua; Jia, Rong; Li, Wei; Xue, Qian; Liu, Jie; Miao, Yide; Wang, Jingtong

2017-01-01

Abstract Rationale: Rhabdomyolysis is a well-known syndrome in clinical practice, although rhabdomyolysis caused by a liver abscess is rarely reported and the patient may lack symptoms that are associated with a primary site of infection. Early recognition of this possibility is needed to avoid diagnostic delay and facilitate treatment. We report the case of a 71-year-old woman with a Klebsiella pneumoniae (KP) pyogenic liver abscess who presented with myasthenia and tea-colored urine and also review the 77 reported cases of bacterial rhabdomyolysis. Patient concerns: The patient was 71 years old and presenting with a 7-day history of myasthenia and a 3-day history of tea-colored urine, but without fever or abdominal pain. Diagnoses: Laboratory testing in our case revealed rhabdomyolysis, and blood culture revealed KP. Abdominal ultrasonography revealed a hypoechoic enclosed mass, and computed tomography (CT) revealed an enclosed low-density mass (8.3 × 6.6 × 6.1 cm). The main diagnoses were a pyogenic liver abscess with rhabdomyolysis. Interventions: Empirically intravenous piperacillin-sulbactam and intravenous potassium treatment, as well as fluid infusions and other supportive treatments were provided after admission. After the diagnosis was confirmed and susceptibility test results were available, we adjusted the antibiotics to cefoperazone and sulbactam, which were maintained for 6 weeks. Outcomes: The patient's symptoms relieved and the abnormal laboratory parameters corrected. Follow-up abdominal ultrasonography at 24 months after her discharge revealed that the abscess had disappeared. Lessons: Early recognition and careful consideration of the underlying cause of rhabdomyolysis are critical to improving the patient's prognosis. Thus, physicians should carefully consider the underlying cause in elderly patients who present with rhabdomyolysis, as they may lack symptoms of a primary infection. PMID:29390582

Transarterial chemoembolization (TACE) is a common treatment modality to locally manage hepatocellular carcinoma. Liver abscess and bile duct injury are common complications of TACE. However, hepatobronchial fistula is a rare complication. Herein, we report a case of lung abscess due to hepatobronchial fistula after TACE. A 67-year-old man, who had underwent TACE 6 months ago, presented cough and bile-colored sputum. He was diagnosed with lung abscess and hepatobronchial fistula. We performed endoscopic retrograde cholangiopancreatography; however, there was no improvement in his symptoms. Thereafter, partial hepatectomy and repair of fistula were successively conducted.

Liver abscess and bacteremia caused by lactobacillus: role of probiotics? Case report and review of the literature.

Lactobacilli are non-spore forming, lactic acid producing, gram-positive rods. They are a part of the normal gastrointestinal and genitourinary microbiota and have rarely been reported to be the cause of infections. Lactobacilli species are considered non-pathogenic organisms and have been used as probiotics to prevent antibiotic associated diarrhea. There are sporadic reported cases of infections related to lactobacilli containing probiotics. In this paper we discuss a case of an 82 year old female with liver abscess and bacteremia from lactobacillus after using probiotics containing lactobacilli in the course of her treatment of Clostridium difficile colitis. The Lactobacillus strain identification was not performed and therefore, both commensal microbiota and the probiotic product should be considered as possible sources of the strain. Lactobacilli can lead to bacteremia and liver abscesses in some susceptible persons and greater awareness of this potential side effect is warranted with the increasing use of probiotics containing lactobacilli.

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.

Roles of cell adhesion and cytoskeleton activity in Entamoeba histolytica pathogenesis: a delicate balance.

The protozoan parasite Entamoeba histolytica colonizes the human large bowel. Invasion of the intestinal epithelium causes amoebic colitis and opens the route for amoebic liver abscesses. The parasite relies on its dynamic actomyosin cytoskeleton and on surface adhesion molecules for dissemination in the human tissues. Here we show that the galactose/N-acetylgalactosamine (Gal/GalNAc) lectin clusters in focal structures localized in the region of E. histolytica that contacts monolayers of enterocytes. Disruption of myosin II activity impairs the formation of these structures and renders the trophozoites avirulent for liver abscess development. Production of the cytoplasmic domain of the E. histolytica Gal/GalNAc lectin in engineered trophozoites causes reduced adhesion to enterocytes. Intraportal delivery of these parasites to the liver leads to the formation of a large number of small abscesses with disorganized morphology that are localized in the vicinity of blood vessels. The data support a model for invasion in which parasite motility is essential for establishment of infectious foci, while the adhesion to host cells modulates the distribution of trophozoites in the liver and their capacity to migrate in the hepatic tissue.

2014-01-01

Background and Objective The primary therapy for deep tissue abscesses is drainage accompanied by systemic antimicrobial treatment. However, the long antibiotic course required increases the probability of acquired resistance, and the high incidence of polymicrobial infections in abscesses complicates treatment choices. Photodynamic therapy (PDT) is effective against multiple classes of organisms, including those displaying drug resistance, and may serve as a useful adjunct to the standard of care by reduction of abscess microbial burden following drainage. Study Design/Materials and Methods Aspirates were obtained from 32 patients who underwent image-guided percutaneous drainage of the abscess cavity. The majority of the specimens (24/32) were abdominal, with the remainder from liver and lung. Conventional microbiological techniques and nucleotide sequence analysis of rRNA gene fragments were used to characterize microbial populations from abscess aspirates. We evaluated the sensitivity of microorganisms to methylene blue-sensitized PDT in vitro both within the context of an abscess aspirate and as individual isolates. Results Most isolates were bacterial, with the fungus Candida tropicalis also isolated from two specimens. We examined the sensitivity of these microorganisms to methylene blue-PDT. Complete elimination of culturable microorganisms was achieved in three different aspirates, and significant killing (p < 0.0001) was observed in all individual microbial isolates tested compared to controls. Conclusions These results and the technical feasibility of advancing optical fibers through catheters at the time of drainage motivate further work on including PDT as a therapeutic option during abscess treatment.

The primary therapy for deep tissue abscesses is drainage accompanied by systemic antimicrobial treatment. However, the long antibiotic course required increases the probability of acquired resistance, and the high incidence of polymicrobial infections in abscesses complicates treatment choices. Photodynamic therapy (PDT) is effective against multiple classes of organisms, including those displaying drug resistance, and may serve as a useful adjunct to the standard of care by reduction of abscess microbial burden following drainage. Aspirates were obtained from 32 patients who underwent image-guided percutaneous drainage of the abscess cavity. The majority of the specimens (24/32) were abdominal, with the remainder from liver and lung. Conventional microbiological techniques and nucleotide sequence analysis of rRNA gene fragments were used to characterize microbial populations from abscess aspirates. We evaluated the sensitivity of microorganisms to methylene blue-sensitized PDT in vitro both within the context of an abscess aspirate and as individual isolates. Most isolates were bacterial, with the fungus Candida tropicalis also isolated from two specimens. We examined the sensitivity of these microorganisms to methylene blue-PDT. Complete elimination of culturable microorganisms was achieved in three different aspirates, and significant killing (P < 0.0001) was observed in all individual microbial isolates tested compared to controls. These results and the technical feasibility of advancing optical fibers through catheters at the time of drainage motivate further work on including PDT as a therapeutic option during abscess treatment. © 2013 Wiley Periodicals, Inc.

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

Rhabdomyolysis is a well-known syndrome in clinical practice, although rhabdomyolysis caused by a liver abscess is rarely reported and the patient may lack symptoms that are associated with a primary site of infection. Early recognition of this possibility is needed to avoid diagnostic delay and facilitate treatment. We report the case of a 71-year-old woman with a Klebsiella pneumoniae (KP) pyogenic liver abscess who presented with myasthenia and tea-colored urine and also review the 77 reported cases of bacterial rhabdomyolysis. The patient was 71 years old and presenting with a 7-day history of myasthenia and a 3-day history of tea-colored urine, but without fever or abdominal pain. Laboratory testing in our case revealed rhabdomyolysis, and blood culture revealed KP. Abdominal ultrasonography revealed a hypoechoic enclosed mass, and computed tomography (CT) revealed an enclosed low-density mass (8.3 × 6.6 × 6.1 cm). The main diagnoses were a pyogenic liver abscess with rhabdomyolysis. Empirically intravenous piperacillin-sulbactam and intravenous potassium treatment, as well as fluid infusions and other supportive treatments were provided after admission. After the diagnosis was confirmed and susceptibility test results were available, we adjusted the antibiotics to cefoperazone and sulbactam, which were maintained for 6 weeks. The patient's symptoms relieved and the abnormal laboratory parameters corrected. Follow-up abdominal ultrasonography at 24 months after her discharge revealed that the abscess had disappeared. Early recognition and careful consideration of the underlying cause of rhabdomyolysis are critical to improving the patient's prognosis. Thus, physicians should carefully consider the underlying cause in elderly patients who present with rhabdomyolysis, as they may lack symptoms of a primary infection. Copyright © 2017 The Authors.

An array of management tools exists within the beef industry to improve animal welfare and productivity; however, the ability to assess the outcomes of these tools is needed. Deficiencies in management commonly manifest as bovine respiratory disease complex or nutritional disorders such as acidosis; therefore, lung, liver, and rumen gross pathology lesions present at slaughter were measured as part of the Harvest Audit Program (HAP) and associations with performance determined. Individual gross pathology data from 19,229 cattle at commercial packing plants in Kansas and Texas were collected. Corresponding individual preharvest and carcass data were obtained on a subset of 13,226 cattle. Associations between lesions and performance were modeled using multivariable mixed effect models. Regression coefficients were used for estimation of lesion associative effects on continuous outcomes and odds ratios for dichotomous outcomes. Across the entire population, 67.3% of the cattle had no pulmonary lesions; 22.5 and 9.8% of cattle displayed mild and severe lesions, respectively. Severe pulmonary lesions were associated with a decreased ADG of 0.07 kg and a HCW 7.1 kg less than cohorts with no pulmonary lesions (P < 0.01). Overall, 68.6% of cattle observed had normal livers. Of cattle severely affected by liver abscesses (A+; 4.6%), 14.9% also displayed severe pulmonary lesions and 28.3% displayed mild pulmonary lesions. Rumenitis lesions were observed in 24.1% of the overall study population. Of cattle with mildly abscessed livers (A-), moderately abscessed livers (A), and severely abscessed livers, 20.6, 21.6, and 9.24% displayed mild or severe rumenitis lesions at slaughter. Severe rumenitis lesions were associated with a significant decrease in ADG and HCW (0.025 and 2.20 kg, respectively; P < 0.001). Although the majority of the cattle in this population would be considered low risk, after adjustments for cattle with multiple lesions, 22.9% of cattle in the overall population were observed with a severe lesion (lung, liver, or rumen). In conclusion, a gross pathology monitoring system is feasible and the 22.9% prevalence of severe lesions (lung, liver, or rumen) indicates that significant opportunity exists to improve beef cattle health, well-being, and productivity. Data generated using HAP may be used to support decisions concerning the implementation or removal of managerial practices and health interventions in beef cattle production systems.

Noniatrogenic pituitary abscess remains a rare clinical entity, and is the indication for surgery in <1% of transsphenoidal approaches. Correct diagnosis of this rare entity is often delayed. Without timely treatment, morbidity and mortality are high. Of the 200 cases reported to date, less than one-half have identified a causative organism. We report the second case of a pituitary abscess caused by Candida species, and also provide an intraoperative video showing the endoscopic management of this pathology. A 33-year-old woman presented with headache, hypopituitarism, and vision loss in the setting of diabetic ketoacidosis, and was found to have multiple abscesses in the liver, lung, kidney, and uterus. Brain magnetic resonance imaging revealed a 15-mm cystic sellar mass with restricted diffusion. The patient underwent urgent evacuation of the abscess via an endoscopic endonasal transsphenoidal route, with obvious purulent material filling the sella, later identified as Candida glabrata. Antimicrobial therapy was refined appropriately, and she exhibited significant improvement in neurologic function, although endocrinopathy has persisted. With timely management, including a combination of surgical drainage and appropriate antimicrobial therapy, neurologic outcomes are good in most cases of pituitary abscess; however, endocrinopathy often does not improve. Although most reported cases with identified causative organisms speciate bacteria, some cases are of fungal etiology and require different antimicrobial agents. This further underscores the importance of identifying the causative agent. Copyright © 2017 Elsevier Inc. All rights reserved.

The future for vaccine development against Entamoeba histolytica

PubMed Central

Quach, Jeanie; St-Pierre, Joëlle; Chadee, Kris

2014-01-01

Entamoeba histolytica is the causative agent of amebiasis, one of the top three parasitic causes of mortality worldwide. In the majority of infected individuals, E. histolytica asymptomatically colonizes the large intestine, while in others, the parasite breaches the mucosal epithelial barrier to cause amebic colitis and can disseminate to soft organs to cause abscesses. Vaccinations using native and recombinant forms of the parasite Gal-lectin have been successful in protecting animals against intestinal amebiasis and amebic liver abscess. Protection against amebic liver abscesses has also been reported by targeting other E. histolytica components including the serine-rich protein and the 29-kDa-reductase antigen. To date, vaccines against the Gal-lectin hold the most promise but clinical trials will be required to validate its efficacy in humans. Here, we review the current strategies and future perspectives involved in the development of a vaccine against E. histolytica. PMID:24504133

2013-01-01

A liver abscess formation is a rare complication of a gallbladder perforation, with a cholecystohepatic communication. Niemeier, in 1934, classified free gallbladder perforations and generalised biliary peritonitis as an acute or a Type I gallbladder perforation, a pericholecystic abscess and localised peritonitis as a subacute or a Type II gallbladder perforation, and cholecystoenteric fistulas as chronic or Type III gallbladder perforations. We are describing a 50–year–old male patient who presented with right upper quadrant pain and was found to have an intrahepatic perforation of the gallbladder. Our patient had a Type II perforation. We have discussed the diagnostic work-up and the management of this rare entity. Due to the high mortality that can be caused by a delay in making the correct diagnosis, a gallbladder perforation represents a special diagnostic and surgical challenge. PMID:24179927

Pyogenic liver abscess: An audit of 10 years’ experience

AIM: To describe our own experience with pyogenic liver abscesses over the past 10 years and investigate the risk factors associated with failure of initial percutaneous therapy. METHODS: A retrospective study of records of 63 PLA patients presenting between 1998 and 2008 to Australian tertiary referral centre, were reviewed. Amoebic and hydatid abscesses were excluded. Demographic, clinical, radiological, and microbiological characteristics, as well as surgical/radiological interventions, were recorded. RESULTS: Sixty-three patients (42 males, 21 females) aged 65 (± 14) years [mean ± (SD)] had prodromal symptoms for a median (interquartile range; IQR) of 7 (5-14) d. Only 59% of patients were febrile at presentation; however, the serum C-reactive protein was elevated in all 47 in whom it was measured. Liver function tests were non-specifically abnormal. 67% of patients had a solitary abscess, while 32% had > 3 abscesses with a median (IQR) diameter of 6.3 (4-9) cm. Causative organisms were: Streptococcus milleri 25%, Klebsiella pneumoniae 21%, and Escherichia coli 16%. A presumptive cryptogenic cause was most common (34%). Four patients died in this series: one from sepsis, two from advanced cancer, and one from acute myocardial infarction. The initial procedure was radiological aspiration ± drainage in 54 and surgery in two patients. 17% underwent surgical management during their hospitalization. Serum hypoalbuminaemia [mean (95% CI): 32 (29-35) g/L vs 28 (25-31) g/L, P = 0.045] on presentation was found to be the only factor related to failure of initial percutaneous therapy on univariate analysis. CONCLUSION: PLA is a diagnostic challenge, because the presentation of this condition is non-specific. Intravenous antibiotics and radiological drainage in the first instance allows resolution of most PLAs; However, a small proportion of patients still require surgical drainage. PMID:21472130

A 38-year-old man was given a diagnosis of as sigmoid colon cancer and underwent sigmoid colectomy. Post-operative pathological staging was stage IIIb. He then underwent adjuvant chemotherapy. One year and 4 months after the surgery, CT scans revealed multiple liver and lung metastases. He was given mFOLFOX6+bevacizumab, which was changed later to FOLFIRI+bevacizumab. After these chemotherapies, he was admitted to the hospital due to sudden abdominal pain and high grade fever. Obstructive jaundice was initially diagnosed, but detailed study of initial CT revealed intragastric wall abscess. After the drainage of the abscess, his conditions improved. We speculated that the abscess formation was caused by mucosal damage due to bevacizumab.

[Immunological status of patients with amebic hepatic abscess].

1975-01-01

The authors studied 10 cases of amoebic hepatic abscess documented by clinical evidence and confirmed by laboratory tests, liver scan and a good response to treatment. The immunological state of the patients was determined by protein electrophoresis, immunoelectrophoresis, counter-immunoelectrophoresis, radial immunodiffusion and roset formation for T and B lymphocytes. It is concluded that the alterations of cellular and humoral immunity is evident in cases of amoebic hepatic abscess; this alterations are more clear in the acute form of the illness and the immunological deficiency is more significant in the celular immunity.

To evaluate the role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the differentiation of hepatic abscesses from non-infected fluid collections. In this retrospective study, 22 hepatic abscesses and 27 non-infected hepatic fluid collections were examined in 27 patients who underwent abdominal MRI including DW-MRI. Two independent observers reviewed T2-weighted + DW-MRI and T2-weighted + contrast-enhanced T1-weighted (CET1W) images in two sessions. Detection rates and confidence levels were calculated and compared using McNemar's and Wilcoxon's signed rank tests, respectively. Apparent diffusion coefficient (ADC) values of abscesses and non-infected fluid collections were compared using the t-test. Receiver operating characteristic (ROC) curves were constructed. There was no statistically significant difference in the accuracy of detecting abscesses using T2-weighted + DW-MRI (both observers: 21/22, 95.5%) versus T2-weighted + CET1W images (observer 1: 21/22, 95.5%; observer 2: 22/22, 100%; p < 0.01). Mean ADC values were significantly lower with abscesses versus non-infected fluid collections (0.83 ± 0.24 versus 2.25 ± 0.61 × 10(-3) mm(2)/s; p < 0.001). With ROC analysis there was good discrimination of abscess from non-infected fluid collections at a threshold ADC value of 1.36 × 10(-3) mm(2)/s. DW-MRI allows qualitative and quantitative differentiation of abscesses from non-infected fluid collections in the liver. Copyright © 2014 The Royal College of Radiologists.

Entamoeba histolytica. Phagocytosis as a virulence factor

PubMed Central

1983-01-01

In this paper, we attempted to define the role of phagocytosis in the virulence of Entamoeba histolytica. We have isolated, from a highly phagocytic and virulent strain, a clone deficient in phagocytosis. Trophozoites of wild-type strain HM1:IMSS were fed with Escherichia coli strain CR34-Thy- grown on 5-bromo,2'-deoxyuridine. The trophozoites that had incorporated the base analog through phagocytosis of the bacteria were killed by irradiation with 310 nm light. The survivors, presumably trophozoites defective in phagocytosis, were grown until log phase and submitted two more times to the selection procedure. Clone L-6, isolated from a subpopulation resulting from this selection procedure, showed 75-85% less erythrophagocytic activity than the wild-type strain. The virulence of clone L-6 and strain HM1:IMSS was measured. The inoculum required to induce liver abscesses in 50% of the newborn hamsters inoculated (AD50) of HM1:IMSS was 1.5 X 10(4) trophozoites. Clone L-6 trophozoites failed to induce liver abscesses in newborn hamsters even with inocula of 5 X 10(5) trophozoites. Virulence revertants were obtained by successive passage of L-6 trophozoites through the liver of young hamsters. The trophozoites that recovered the ability to produce liver abscesses simultaneously recuperate high erythrophagocytic rates. These results show that phagocytosis is involved in the aggressive mechanisms of E. histolytica. PMID:6313842

Low serum albumin concentration is a predictor of failure of source control for intra-abdominal infection. However, data on dynamics of albumin synthesis in these patients and to what extent these changes contribute to hypoalbuminemia are relatively scarce. We investigated in a group of patients with gastrointestinal fistula the dynamic response of liver albumin synthesis to intra-abdominal abscess and how these related to hypoalbuminemia and circulating endocrine hormone profiles. Eight gastrointestinal fistula patients scheduled to undergo percutaneous abscess sump drainage were enrolled prospectively to measure albumin synthesis rates at different stages of the inflammatory response (immediately after diagnosis and 7 d following sump drainage when clinical signs of intra-abdominal sepsis had been eradicated). Eight age-, sex-, and body mass index-matched intestinal fistula patients were studied as control patients. Consecutive arterial blood samples were drawn during a primed-constant infusion (priming dose: 4 micromol·kg(-1), infusion rate: 6 micromol·kg(-1)·min(-1)) to determine the incorporation rate of L-[ring-(2)H5]-phenylalanine directly into plasma albumin using gas chromatography/mass spectrometry analysis. Patients suffering from intra-abdominal infection had reduced plasma albumin and total plasma protein concentrations, compared with control patients. Albumin fractional synthesis rates in patients with intra-abdominal abscess were decreased, compared with those in the control group. When the source of infection was removed, albumin synthesis rates returned to control values, whereas albumin concentrations did not differ significantly from the corresponding concentrations in control subjects and patients with intra-abdominal abscess. Despite nutritional intervention, albumin synthesis rate is decreased in intestinal fistula patients with intra-abdominal abscess; albumin synthesis returns to control values during convalescence.

PubMed

Davido, B; Dinh, A; Rouveix, E; Crenn, P; Hanslik, T; Salomon, J

2017-09-01

Splenic abscess is septic collection which occurs after haematogenous spread or local dissemination. Splenic abscess is an uncommon and rare condition, more frequently affecting male and immunocompromised patients. There are no guidelines regarding its diagnosis and management. Computed tomography (CT) scan is highly sensitive and specific (95% and 92%, respectively) in the diagnosis of splenic abscess. Diagnosis is based on blood cultures which are positive in 24 to 80% of cases. Bacterial growth culture of abscess after drainage is more efficient (50-80%) and can be performed after surgery or percutaneous drainage under imaging, including CT scan. Microorganisms involved are frequently enterobacteriaceae, gram-positive cocci and anaerobes. This particular ecology leads to an empiric broad-spectrum antibiotic therapy, with a variable duration, from 10days to more than one month. Management remains very close to the one applied in case of liver abscesses. The role of splenectomy in the prevention of recurrence remains controversial. We reviewed the literature regarding splenic abscesses, from diagnosis to therapy. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS.

Oral Campylobacter Species Involved in Extraoral Abscess: a Report of Three Cases

PubMed Central

Han, Xiang Y.; Tarrand, Jeffrey J.; Rice, David C.

2005-01-01

Oral Campylobacter species are rarely reported to cause extraoral infections. Here we present three cases of extraoral abscess caused by an oral Campylobacter sp. and a Streptococcus sp. The Campylobacter species were all isolated anaerobically and identified by sequencing analysis of the 16S rRNA gene. The cases included a breast abscess caused by Campylobacter rectus and a non-group A beta-hemolytic streptococcus in a patient with lymphoma, a liver abscess caused by Campylobacter curvus and an alpha-hemolytic streptococcus in a patient with complicated ovarian cancer, and a postobstructive bronchial abscess caused by C. curvus and group C beta-hemolytic Streptococcus constellatus in a patient with lung cancer. The abscesses were drained or resected, and the patients were treated with antibiotics with full resolution of the lesions. The C. curvus cases are likely the first reported infections by this organism, and the C. rectus case represents the second such reported extraoral infection. PMID:15872299

Melioidosis is a tropical infectious disease associated with significant mortality due to early onset of sepsis. We sought to review case reports of melioidosis from Malaysia. We conducted a computerized search of literature resources including PubMed, OVID, Scopus, MEDLINE and the COCHRANE database to identify published case reports from 1975 to 2015. We abstracted information on clinical characteristics, exposure history, comorbid conditions, management and outcome. Overall, 67 cases were reported with 29 (43%) deaths; the median age was 44 years, and a male preponderance (84%) was noted. Forty-one cases (61%) were bacteremic, and fatal septic shock occurred in 13 (19%) within 24-48 hours of admission; nine of the 13 cases were not specifically treated for melioidosis as confirmatory evidence was available only after death. Diabetes mellitus (n = 36, 54%) was the most common risk factor. Twenty-six cases (39%) had a history of exposure to contaminated soil/water or employment in high-risk occupations. Pneumonia (n = 24, 36%) was the most common primary clinical presentation followed by soft tissue abscess (n = 22, 33%). Other types of clinical presentations were less common-genitourinary (n = 5), neurological (n = 5), osteomyelitis/septic arthritis (n = 4) and skin (n = 2); five cases had no evidence of a focus of infection. With regard to internal foci of infection, abscesses of the subcutaneous tissue (n = 14, 21%) was the most common followed by liver (18%); abscesses of the spleen and lung were the third most common (12% each). Seven of 56 males were reported to have prostatic abscesses. Mycotic pseudoaneurysm occurred in five cases. Only one case of parotid abscess was reported in an adult. Of the 67 cases, 13 were children (≤ 18 years of age) with seven deaths; five of the 13 were neonates presenting primarily with bronchopneumonia, four of whom died. Older children had a similar presentation as adults; no case of parotid abscess was reported among children. The clinical patterns of cases reported from Malaysia are consistent for the most part from previous case reports from South and Southeast Asia with regard to common primary presentations of pneumonia and soft tissue abscesses, and diabetes as a major risk factor. Bacteremic melioidosis carried a poor prognosis and septic shock was strong predictor of mortality. Differences included the occurrence of: primary neurological infection was higher in Malaysia compared to reports outside Malaysia; internal foci of infection such as abscesses of the liver, spleen, prostate, and mycotic pseudoaneurysms were higher than previously reported in the region. No parotid abscess was reported among children. Early recognition of the disease is the cornerstone of management. In clinical situations of community-acquired sepsis and/or pneumonia, where laboratory bacteriological confirmation is not possible, empirical treatment with antimicrobials for B. pseudomallei is recommended.

Tuberculosis of the liver in association with generalized miliary tuberculosis is not an uncommon clinical entity. A solitary tuberculous liver abscess, however, is rare. Two such cases, in which there was no clinical evidence of extrahepatic tuberculosis, are reported. The similarities between this condition and other causes of hepatic lesions are discussed, with particular emphasis placed on the imaging patterns of various diagnostic imaging procedures.

OBJECTIVES: Septic pulmonary embolism is an uncommon but life-threatening disorder. However, data on patients with septic pulmonary embolism who require critical care have not been well reported. This study elucidated the clinicoradiological spectrum, causative pathogens and outcomes of septic pulmonary embolism in patients requiring critical care. METHODS: The electronic medical records of 20 patients with septic pulmonary embolism who required intensive care unit admission between January 2005 and December 2013 were reviewed. RESULTS: Multiple organ dysfunction syndrome developed in 85% of the patients, and acute respiratory failure was the most common organ failure (75%). The most common computed tomographic findings included a feeding vessel sign (90%), peripheral nodules without cavities (80%) or with cavities (65%), and peripheral wedge-shaped opacities (75%). The most common primary source of infection was liver abscess (40%), followed by pneumonia (25%). The two most frequent causative pathogens were Klebsiella pneumoniae (50%) and Staphylococcus aureus (35%). Compared with survivors, nonsurvivors had significantly higher serum creatinine, arterial partial pressure of carbon dioxide, and Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores, and they were significantly more likely to have acute kidney injury, disseminated intravascular coagulation and lung abscesses. The in-hospital mortality rate was 30%. Pneumonia was the most common cause of death, followed by liver abscess. CONCLUSIONS: Patients with septic pulmonary embolism who require critical care, especially those with pneumonia and liver abscess, are associated with high mortality. Early diagnosis, appropriate antibiotic therapy, surgical intervention and respiratory support are essential. PMID:27759843

Sepsis due to Enterobacter aerogenes (E. aerogenes) is rare after liver transplantation but is also a serious infection that may cause liver abscess. The purpose of this case report is to relate an unusual presentation of liver transplantation to show how successive treatment can be an appropriate option in septic patients after liver transplantation. We report on a patient with liver transplantation who developed sepsis due to extended spectrum beta-lactamases and AmpC-producing E. aerogenes. A 39-year-old man had a biliary fistula and then was found to have multiple liver abscesses through abdominal ultrasound and an abdominal computed tomography scan, and carbapenem-sensitive E. aerogenes infection was confirmed. The patient was not successfully treated with conservative treatment consisting of intravenous carbapenems, percutaneous transhepatic cholangial drainage, and biliary stent placement by endoscopic retrograde cholangiopancreatography, so a second liver transplantation followed. Carbapenem-resistant E. aerogenes was detected in bile and blood after a five-week course of carbapenem therapy. The patient developed septic shock and multiple organ dysfunction syndrome. We first report an unusual case of sepsis caused by E. aerogenes after liver transplantation in China. Carbapenem-resistant E. aerogenes finally leads to uncontrolled sepsis with current antibiotics. We hypothesize that the infection developed as a result of biliary fistula and predisposing immunosuppressive agent therapy. Further research is progressing on the aspect of immunomodulation therapy.

Tuberculosis and liver disease: management issues.

Tuberculosis is one of the most common diseases in India and has attained epidemic proportions. Tuberculosis and liver are related in many ways. Liver disease can occur due to hepatic tuberculosis or the treatment with various anti-tubercular drugs may precipitate hepatic injury or patients with chronic liver disease may develop tuberculosis and pose special management problems. Tuberculosis per se can affect liver in three forms. The most common form is the diffuse hepatic involvement, seen along with pulmonary or miliary tuberculosis. The second is granulomatous hepatitis and the third, much rarer form presents as focal/local tuberculoma or abscess. Tubercular disease of liver occurring along with pulmonary involvement as in disseminated tuberculosis is treated with standard regimen for pulmonary tuberculosis. Granulomatous hepatitis and tubercular liver abscess are treated like any other extra-pulmonary tubercular lesions without any extra risk of hepatotoxicity by anti-tubercular drugs. Treatment of tuberculosis in patients who already have a chronic liver disease poses various clinical challenges. There is an increased risk of drug induced hepatitis in these patients and its implications are potentially more serious in these patients as their hepatic reserve is already depleted. However, hepatotoxic anti-tubercular drugs can be safely used in these patients if the number of drugs used is adjusted appropriately. Thus, the main principle is to closely monitor the patient for signs of worsening liver disease and to reduce the number of hepatotoxic drugs in the anti-tubercular regimen according to the severity of underlying liver disease.

Background Melioidosis is a tropical infectious disease associated with significant mortality due to early onset of sepsis. Objective We sought to review case reports of melioidosis from Malaysia. Methods We conducted a computerized search of literature resources including PubMed, OVID, Scopus, MEDLINE and the COCHRANE database to identify published case reports from 1975 to 2015. We abstracted information on clinical characteristics, exposure history, comorbid conditions, management and outcome. Results Overall, 67 cases were reported with 29 (43%) deaths; the median age was 44 years, and a male preponderance (84%) was noted. Forty-one cases (61%) were bacteremic, and fatal septic shock occurred in 13 (19%) within 24–48 hours of admission; nine of the 13 cases were not specifically treated for melioidosis as confirmatory evidence was available only after death. Diabetes mellitus (n = 36, 54%) was the most common risk factor. Twenty-six cases (39%) had a history of exposure to contaminated soil/water or employment in high-risk occupations. Pneumonia (n = 24, 36%) was the most common primary clinical presentation followed by soft tissue abscess (n = 22, 33%). Other types of clinical presentations were less common—genitourinary (n = 5), neurological (n = 5), osteomyelitis/septic arthritis (n = 4) and skin (n = 2); five cases had no evidence of a focus of infection. With regard to internal foci of infection, abscesses of the subcutaneous tissue (n = 14, 21%) was the most common followed by liver (18%); abscesses of the spleen and lung were the third most common (12% each). Seven of 56 males were reported to have prostatic abscesses. Mycotic pseudoaneurysm occurred in five cases. Only one case of parotid abscess was reported in an adult. Of the 67 cases, 13 were children (≤ 18 years of age) with seven deaths; five of the 13 were neonates presenting primarily with bronchopneumonia, four of whom died. Older children had a similar presentation as adults; no case of parotid abscess was reported among children. Conclusions The clinical patterns of cases reported from Malaysia are consistent for the most part from previous case reports from South and Southeast Asia with regard to common primary presentations of pneumonia and soft tissue abscesses, and diabetes as a major risk factor. Bacteremic melioidosis carried a poor prognosis and septic shock was strong predictor of mortality. Differences included the occurrence of: primary neurological infection was higher in Malaysia compared to reports outside Malaysia; internal foci of infection such as abscesses of the liver, spleen, prostate, and mycotic pseudoaneurysms were higher than previously reported in the region. No parotid abscess was reported among children. Early recognition of the disease is the cornerstone of management. In clinical situations of community-acquired sepsis and/or pneumonia, where laboratory bacteriological confirmation is not possible, empirical treatment with antimicrobials for B. pseudomallei is recommended.

Extra-intestinal manifestations of Clostridium difficile infection are uncommon. Most cases are associated with gastrointestinal disease and often occur as a mixed infection with other gut flora. We report a case of breast abscess following monomicrobial C. difficile bacteraemia in a female with background chronic hepatitis C infection and alcoholic liver disease. No evidence of colitis was found. Our case shows that C. difficile is indeed capable of spreading from the gastrointestinal tract.

Amebic lung abscess with concurrent lung cancer, but without either a liver abscess or amebic colitis, is extremely uncommon. Here, we report a 70-year-old man presenting with pulmonary amebiasis and coexisting lung adenocarcinoma. During his first-time hospitalization, the diagnosis of lung amebiasis was confirmed by morphological observation and PCR in formalin-fixed and paraffin-embedded sediments of pleural effusion. Almost four months later, the patient was readmitted to hospital for similar complaints. On readmission, lung adenocarcinoma was diagnosed by liquid-based sputum cytology and thought to be delayed because coexisting amebic lung abscess. This case demonstrated that sediments of pleural effusion may be used for further pathological examination after routine cytology has shown negative results. At the same time, we concluded that lung cancer may easily go undetected in the patients with pulmonary amebiasis and repetitive evaluation by cytology and imaging follow-up are useful to find potential cancer.

A 66-year-old man was admitted to our hospital with high fever. We diagnosed a gas-containing liver abscess and performed percutaneous abscess drainage. However, 15 hours after admission, he developed massive intravascular hemolysis and acidosis. Sepsis due to Clostridium perfringens was suspected and we treated the patient intensively with multidisciplinary approaches, including antibiotics, mechanical ventilation, and renal replacement therapy. Furthermore, we administered freeze-dried gas gangrene antitoxin. Despite intensive care, the patient died 43 hours after admission.

Hepatic rupture

Abstract Rationale: Currently, percutaneous catheter drainage (PCD) is regarded as the first-line treatment modality of pyogenic liver abscess. Severe complications associated with PCD were uncommon. Hepatic rupture is an uncommon but life-threatening liver trauma with high mortality. Its management is challenging because a delay in the diagnosis may lead to fatal hemorrhagic shock. To our knowledge, PCD-associated hepatic rupture has never been reported. Patient concerns: We report herein a rare case of PCD-associated hepatic rupture. Its clinical courses and our therapeutic approaches are presented. Moreover, the clinical significance, underlying causes, and current views on severe liver trauma management will be discussed briefly. Diagnoses: A diabetic patient suffering from fever and malaise was diagnosed with a pyogenic liver abscess. PCD was performed because intravenous antibiotics were ineffective. The patient developed a liver rupture following PCD, with clinical and imaging confirmation but without further progression. Interventions: Surgical repair and vascular intervention were both inappropriate. As a result, medical treatments with supportive care were adopted and were found to be effective. Outcomes: The patient's condition improved gradually, with stabilized imaging and laboratory performance. He recovered uneventfully during follow-ups. Lessons: Hepatic rupture should be listed as an extremely rare but severe complication of PCD. Immediate suspicion and effective intervention may avoid an unfavorable consequence. PMID:29480839

Pyogenic liver abscess (PLA) is relatively common in patients with diabetes mellitus (DM), but it is unclear whether there are differences between patients with and without DM. We conducted a study to identify the possible differences and factors that affect fatality. We included PLA patients treated at a medical center from April 2001 to March 2004 and compared the clinical characteristics of patients with and without DM. We applied chi-square, Fisher's exact, and t-tests to evaluate the differences between the two groups and used logistic regressions to identify predictors of fatality. Of the 377 patients included, 182 (48.3%) had DM. Patients with DM had higher prevalence rates of cryptogenic etiology, gas-forming nature, thrombocytopenia, hyperglycemia, growth of Klebsiella pneumonia in blood cultures, metastatic infection, and bacteremia, but lower prevalence rates of biliary origin, right upper quadrant pain, and growth of Escherichia coli in pus cultures. Whereas creatinine >1.3 mg/dl (adjusted odds ratio (OR) 7.3, 95% confidence interval (CI) 2.2-24.5) and gas-forming nature (adjusted OR 9.4, 95% CI 3.0-24.5) were predictors of fatality, DM was not. We discovered that C-reactive protein and neutrophil were good biomarkers of PLA, but not asparate aminotransferase and alanine aminotransferase. PLA patients with and without DM have different clinical characteristics, but DM is not a predictor of fatality. We have identified several biomarkers that might help reduce the misdiagnosis of PLA.

Klebsiella pneumoniae (KP) is the most common pathogen of pyogenic liver abscess in East and Southeast Asia and diabetes mellitus (DM) is a major risk factor. The effect and mechanism of diabetes on KP liver abscess was examined in streptozotocin-induced diabetic mice and Akita mice (C57BL/6J-Ins2Akita). KP translocation to liver and plasma alaine transaminase levels were increased and liver clearance of KP was decreased in DM mice. Diabetic mice exhibited overgrowth of Enterococcus as well as E.coli and decreased lactobacilli/bifidas growth in intestine, increased intestinal iNOS protein and nitrite levels in portal vein, and increased IL-1β and TNF-α expression of Kupffer cells. Fructooligosaccharides (FOS) or dead L. salivarius (dLac) supplementation reversed diabetes-induced enteric dysbiosis, NO levels in portal vein, and KP translocation to liver. L-NAME treatment decreased intestinal iNOS protein expression as well as Kupffer cell activation and increased liver clearance of KP in DM mice. Dead E.coli (2×108 CFU/ml) feeding for one week induced iNOS and TLR4 expression of intestine in germ-free (GF) mice. Dead bacteria feeding induced IL-1β and TNF-α expression of Kupffer cells in GF mice but not in GF TLR4-/- mice. In conclusion, balance of intestinal microflora is important for preventing intestinal iNOS expression, Kupffer cell activation, and KP liver translocation in diabetes. Reversal of diabetes-induced enteric dysbiosis with FOS or dead L. salivarius decreases diabetes-induced intestinal iNOS expression and KP liver translocation. Diabetes induces Kupffer cell activation and KP liver translocation through enteric dysbiosis and nitric oxide production. PMID:28493939

Sparganosis of liver: a rare entity and review of literature.

Humans are known to serve as the secondary intermediate host for some larval forms of canine or feline tapeworms. Sparganosis is caused by plerocercoid larva of Spirometra of which there are three main species; Spirometra mansoni (or Spirometra erinaceieuropaei), Spirometra mansonoides and Spirometra proliferum. A one-and-half-year-old patient presenting with febrile illness was diagnosed radiologically as a case of liver abscess. The aspirate from the abscess cavity had a thin thread-like worm which was identified as a larval stage of Pseudophyllidea that was further confirmed as belonging to genus Spirometra. Aspiration of the worm and antiparasitic therapy with metronidazole led to complete recovery. Reports of sparganosis from Indian subcontinent are scanty and these cases had involvement of brain, kidney and eye. To the best of our knowledge this is the first case of hepatic sparganosis from India.

Hepatobiliary fascioliasis in non-endemic zones: a surprise diagnosis.

PubMed

Jha, Ashish Kumar; Goenka, Mahesh Kumar; Goenka, Usha; Chakrabarti, Amrita

2013-03-01

Fascioliasis is a zoonotic infection caused by Fasciola hepatica. Because of population migration and international food trade, human fascioliasis is being an increasingly recognised entity in nonendemic zones. In most parts of Asia, hepatobiliary fascioliasis is sporadic. Human hepatobiliary infection by this trematode has two distinct phases: an acute hepatic phase and a chronic biliary phase. Hepatobiliary infection is mostly associated with intense peripheral eosinophilia. In addition to classically defined hepatic phase and biliary phase fascioliasis, some cases may have an overlap of these two phases. Chronic liver abscess formation is a rare presentation. We describe a surprise case of hepatobiliary fascioliasis who presented to us with liver abscess without intense peripheral eosinophilia, a rare presentation of human fascioliasis especially in non-endemic zones.

Objective To characterize the Entamoeba histolytica (E. histolytica) antigen(s) recognized by moribound amoebic liver abscess hamsters. Methods Crude soluble antigen of E. histolytica was probed with sera of moribund hamsters in 1D- and 2D-Western blot analyses. The antigenic protein was then sent for tandem mass spectrometry analysis. The corresponding gene was cloned and expressed in Escherichia coli BL21-AI to produce the recombinant E. histolytica ADP-forming acetyl-CoA synthetase (EhACS) protein. A customised ELISA was developed to evaluate the sensitivity and specificity of the recombinant protein. Results A ∼75 kDa protein band with a pI value of 5.91-6.5 was found to be antigenic; and not detected by sera of hamsters in the control group. Tandem mass spectrometry analysis revealed the protein to be the 77 kDa E. histolytica ADP-forming acetyl-CoA synthetase (EhACS). The customised ELISA results revealed 100% sensitivity and 100% specificity when tested against infected (n=31) and control group hamsters (n=5) serum samples, respectively. Conclusions This finding suggested the significant role of EhACS as a biomarker for moribund hamsters with acute amoebic liver abscess (ALA) infection. It is deemed pertinent that future studies explore the potential roles of EhACS in better understanding the pathogenesis of ALA; and in the development of vaccine and diagnostic tests to control ALA in human populations.

Metronidazole is an antibiotic classically used against most anaerobic bacteria and protozoa. Because an intravenous form of metronidazole has recently entered the market, the use of this antibiotic is attracting renewed interest in many clinical settings in Japan. However, neurotoxicity is a major adverse event: in the central nervous system metronidazole-induced encephalopathy is a rare but serious condition. We performed a literature review of 34 cases including 2 of our cases, 25 from domestic conference abstracts, and 7 cases presented in full research papers. The mean patient age was 64.7 years. The conditions most commonly treated with metronidazole were brain abscess (35.3%), liver abscess (17.6%), and Clostridium difficile infection (14.7%). The most common predisposing conditions were liver dysfunction (26.5%), diabetes and other metabolic disorders (20.6%), and hematologic or solid organ malignancy (14.7%). The mean period of administration before the onset of encephalopathy symptoms was 61.3 days, and the mean total dose was 95.9g. The initial chief complaints were dysarthria (in 70.6% of the cases) and ataxia (61.8%); 82.4% of the cases were diagnosed on the basis of MRI (T2-weighted or FLAIR imaging). The key imaging finding was high intensity in the dentate nucleus bilaterally (82.4%). Stopping the metronidazole led to symptom remission within 8.5 days, but the MRI changes remained longer than the clinical symptoms. Two patients (6.0%) developed irreversible disturbance of consciousness. Although the mechanisms of this type of encephalopathy have not yet been elucidated, localized nerve-cell edema is likely caused by decreased metronidazole metabolism associated with liver and metabolic dysfunction. Careful observation for neurologic signs should be conducted during the treatment of brain abscesses associated with metronidazole administration, because patients with brain abscesses are naturally at high risk of metronidazole-induced encephalopathy.

Pyogenic liver abscess (PLA) formation is thought to originate from the transmission of infection via three major routes including the biliary tract, portal vein and hepatic artery. However, about 50% of PLA cases are considered to be cryptogenic. Here we report an unusual autopsy case of PLA associated with periodontopathic bacterial infection. A 59-year-old female suddenly developed cardiopulmonary arrest and died. Despite macroscopic and microscopic examinations, the infectious routes and source of infection were unidentified, and the case appeared to be cryptogenic. Since this patient had suffered severe periodontitis for a long period of time, we investigated the involvement of periodontal infection in PLA formation by performing immunohistochemical analyses. We identified several periodontopathic bacterial species in the PLA of this patient, including Fusobacterium nucleatum, Treponema denticola, Prevotella intermedia and Porphyromonas gingivalis. Thus, we demonstrate here that periodontal infection is a potential source of infection in the formation of PLA.

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

AIM: To analyze 67 cases of splenic abscess in a medical center of Taiwan during a period of 19 years. METHODS: From January 1986 to December 2004, a total of 67 patients with splenic abscess were enrolled for the retrospective study. The clinical characteristics, underlying diseases, organism spectra, therapeutic methods, APACHE II scores, and mortality rates were analyzed. RESULTS: There were 41 males and 26 females with the mean age of 54.1 ± 14.1 years. Multiple splenic abscesses (MSA) account for 28.4% and solitary splenic abscess in 71.6% of the patients. Twenty-six of sixty-seven patients (35.8%) had extrasplenic abscesses, with leading site of liver (34.6%). Microbiological cultures were positive in 58 patients (86.6%), with 71.8% in blood culture and 93.5% in abscess culture. Gram negative bacillus (GNB) infection predominated (55.2%), with leading pathogen of Klebsiella pneumoniae (22.4%), followed by gram positive coccus (GPC) infection (31%). Splenectomy was performed in 26 patients (38.8%), percutaneous drainage or aspiration in 21 (31.3%), and antibiotic therapy alone in 20 patients (29.9%). Eventually, 12 of 67 patients expired (17.9 %). By statistics, spleen infected with GNB was likely to develop multiple abscesses compared with infection with GPC (P = 0.036). Patients with GNB infection (P = 0.009) and multiple abscesses (P = 0.011) experienced a higher mortality rate than patients with GPC infection and solitary abscess. The mean APACHE II score of 12 expired patients (16.3 ± 3.2) was significantly higher than that of the 55 survivals (7.2 ± 3.8) (P < 0.001). CONCLUSION: MSA, GNB infection, and high APACHE II scores are poor prognostic factors. Early surgical intervention should be encouraged when these risk factors are present. PMID:16489650

Abstract Background: The cancer of the splenic flexure of the colon is a rare medical entity with severe morbidity because of its insidious onset. Methods: We present the case of a 59-year-old male patient with dull left upper quadrant pain, leukocytosis, and anemia. A splenic abscess described as an air-fluid level with splenocolic fistula was found on CT scan imaging. Surgery was done for splenic pus drainage. He was again admitted 2 months later for intestinal obstruction. Results: An exploratory laparotomy showed multiple hard, gray liver nodules as well as a hard mass in the small bowel. Owing to extensive adhesions and a late stage of cancer involvement, the splenic flexure tumor was not resected. A loop transverse colostomy was done and a ColoplastTM Colostomy bag placed. We also reviewed the literature-linking colon cancer and splenic abscess with specific attention to the carcinoma of the splenic flexure. As the latter invades through the spleen matter, there is the creation of a splenocolic fistula, which allows the migration of normal gut flora into the spleen. This leads to the formation of the splenic abscess. Conclusion: This is the 13th case report pertaining to invading colonic cancer causing a splenic abscess. Although the treatment for splenic abscesses is shifting from splenectomy to image-guided percutaneous pus drainage, the few reported cases make the proper management of such complication still unclear.

Gene Expression Profiling in Entamoeba histolytica Identifies Key Components in Iron Uptake and Metabolism

2014-01-01

Entamoeba histolytica is an ameboid parasite that causes colonic dysentery and liver abscesses in humans. The parasite encounters dramatic changes in iron concentration during its invasion of the host, with relatively low levels in the intestinal lumen and then relatively high levels in the blood and liver. The liver notably contains sources of iron; therefore, the parasite's ability to use these sources might be relevant to its survival in the liver and thus the pathogenesis of liver abscesses. The objective of the present study was to identify factors involved in iron uptake, use and storage in E. histolytica. We compared the respective transcriptomes of E. histolytica trophozoites grown in normal medium (containing around 169 µM iron), low-iron medium (around 123 µM iron), iron-deficient medium (around 91 µM iron), and iron-deficient medium replenished with hemoglobin. The differentially expressed genes included those coding for the ATP-binding cassette transporters and major facilitator transporters (which share homology with bacterial siderophores and heme transporters) and genes involved in heme biosynthesis and degradation. Iron deficiency was associated with increased transcription of genes encoding a subset of cell signaling molecules, some of which have previously been linked to adaptation to the intestinal environment and virulence. The present study is the first to have assessed the transcriptome of E. histolytica grown under various iron concentrations. Our results provide insights into the pathways involved in iron uptake and metabolism in this parasite. PMID:25210888

Liver abscesses (LA) are a source of economic loss for feedlot cattle feedlots, and the 2017 veterinary feed directive has restricted further use of tylosin phosphate to prevention and control of LA. Our objective was to evaluate effects of intermittent tylosin phosphate feeding on incidence and severity of liver abscesses in feedlot cattle and presence of total antimicrobial resistant Enterococcus spp. Steers (n=312, 411.4 ± 6.71 kg) were blocked by initial BW and randomly assigned to a treatment group. Treatments included a negative control group (no tylosin phosphate throughout the finishing period), a positive control group (tylosin phosphate fed continuously throughout the finishing period), and a group that received tylosin phosphate off-label by feeding the drug on a repeated intermittent basis (1 week on, 2 weeks off). Steers were housed in 24 soil-surfaced pens with 13 steers per pen. Bodyweights of cattle were obtained every 28 d and at the end of 119 d the steers were weighed and harvested at a commercial abattoir. Fecal samples were collected on day 0, 21, and 118 to characterize antimicrobial resistant Enterococcus spp. Total LA percentage was greater (P = 0.012) for the no tylosin phosphate treatment compared to the other treatments, but did not differ between the continuous tylosin phosphate treatment and the intermittently fed tylosin phosphate treatment (P = 0.716). No difference was observed among treatments for ADG (P = 0.21), DMI (P = 0.28), or G:F (P = 0.75). Marbling score was lower (P = 0.022) for tylosin phosphate treatment when compared both to intermittent treatment and continuous tylosin phosphate treatment. Enterococcus spp. bacterial counts did not differ by treatment group over time (P > 0.05); however, there was a strong period effect for macrolide resistance among all groups (P < 0.01), suggesting an important environmental component as cattle were first placed in pens and then progressed through the feeding period. We conclude that feeding tylosin phosphate intermittently during the finishing phase decreases the total percentage of LA and maintains feedlot performance and carcass characteristics to the same extent as feeding tylosin phosphate throughout the finishing phase; further, we hypothesize that enteric antimicrobial resistance is a result of longer term antibiotic usage in a particular environment rather than a direct short-term result of the treatment during any given feeding period.

Bronchobiliary fistula (BBF), a rare complication of liver disease, is an abnormal communication between the biliary tract and bronchial tree. BBF may occur as a consequence of local liver infections such as hydatid or amebic disease, pyogenic liver abscess or trauma to the liver, obstruction of biliary tract, and tumor. As such management of liver disease with BBF is very difficult and often associated with a high rate of morbidity and mortality. Therefore, timely diagnosis of BBF is imperative. Hepatobiliary scintigraphy along with hybrid single photon emission computed tomography/computed tomography using Tc99m-mebrofenin is a very useful noninvasive imaging modality, in the diagnosis of BBF.

Ninety-six medium frame, Angus and Angus cross steer calves (average initial weight 540 lb.) were allotted to a heavy or light weight block and then randomly assigned to one of four dietary treatments for a 167 or 189-day finishing phase, respectively. Treatments were control (supplemental soybean meal), alfalfa leaf meal (ALM) providing 33%, 66%, 100% of supplemental protein. Finishing diets were formulated to contain .61 Mcal NE{sub g}/lb dry matter, 12.5% crude protein, .6 % Ca and .3 % P. There were no significant (P >.05) effects of dietary treatments on daily gain or dry matter required /lb of gain.more » Steers fed 100 % ALM consumed more (P <.05) dry matter than steers fed either of the other three treatments. Dry matter consumption increased linearly (P >.05) with increasing ALM. There was no significant (P >.05) dietary treatment effect on marbling, KPH %, yield grade, quality grade, or liver abscesses. There was an apparent trend in reduced liver abscess incidence in steers fed 100 % ALM. Steers fed 66 % ALM had significantly (P <.05) greater backfat measurements, backfat also had a cubic effect (P <.05). Hot carcass weight had a quadratic relation (P <.05) with level of ALM. Substituting alfalfa leaf meal for soybean meal in diets of finishing steers increased DM intake, but this increase was accompanied by an increase in gain which resulted in similar feed efficiency. There may be an advantage in blending ALM and soybean meal as feed efficiency was improved when cattle were fed the blend. Also, feeding ALM may result in lower incidence of liver abscess.« less

The 29-kDa peripheral membrane protein of Entamoeba histolytica has recently been demonstrated to have epitopes on pathogenic clinical isolates which were not detected by monoclonal antibodies on nonpathogenic isolates. To analyze the serological response to this protein, we tested 93 serum specimens (from 33 patients with amebic liver abscess, 7 patients with colitis, 2 patients with ameboma, 18 individuals harboring a nonpathogenic zymodeme strain, 10 healthy Mexican migrant workers, and 23 healthy controls) by enzyme-linked immunosorbent assay (ELISA) using immunoaffinity-purified native or recombinant protein. When tested by ELISA with the native antigen, 79% (26 of 33) of the serum specimens from patients with amebic liver abscess, 4 of 9 serum specimens from symptomatic patients with colitis or ameboma, and serum from one migrant worker were positive. None of the 18 subjects harboring a nonpathogenic strain or 23 control individuals were seropositive to the native antigen (sensitivity, 71%; specificity, 98%). Of 30 serum specimens from patients with amebic liver abscess tested with recombinant antigen, 27 were seropositive (90%). In addition, six patients with colitis or ameboma and two individuals who harbored a nonpathogenic strain were seropositive to the recombinant antigen. One healthy Mexican migrant worker tested positive by both ELISAs (sensitivity, 87%; specificity, 94%). Immunoblotting of 51 serum specimens to sodium dodecyl sulfate-denatured native 29-kDa protein was less sensitive (65%) than ELISA in detecting serum antibodies to the antigen. These results suggest a similar antibody response to native and recombinant antigens (r = 0.86) and support the potential utility of a quantitative assay with defined recombinant antigen for the serodiagnosis of invasive amebiasis in nonendemic areas in conjunction with other diagnostic tools.

Invasive aspergillosis is one of the most important and fatal complications after liver transplant, especially in patients with involvement of the central nervous system. We present a case of a patient who developed cerebral and pulmonary aspergillosis, coinfected with cytomegalovirus, after liver transplant for toxic fulminant hepatitis. The patient was treated successfully with neurosurgical intervention and voriconazole. Voriconazole is considered more effective in cerebral aspergillosis than other anti-fungal agents due to the greater penetration into central nervous system and higher cerebrospinal fluid and brain tissue levels.

The large intestine reacts relatively monomorphically to different stimuli. From this differential-diagnostic problems may result. The history of a patient is described which could be pursued clinically over 12 weeks and during the course of which the correction of the diagnosis ulcerative colitis into amoebic colitis was necessary. It is concluded that in every symptomatology of colitis bacterial and parasitologic examinations of the faeces should be performed primarily specially if there is a history of overseas travel. In these cases it must be also thought of spontaneous amoebic infections.

Although infectious diseases are the most prevalent cause of fevers of unknown origin (FUO), this diagnosis remains challenging in some pediatric patients. Imaging exams, such as computed tomography (CT) are frequently required during the diagnostic processes. The presence of multiple hypoattenuating scattered images throughout the liver associated with the history of cohabitation with cats should raise the suspicion of the diagnosis of cat-scratch disease (CSD), although the main etiologic agent of liver abscesses in childhood is S taphylococcus aureus . Differential diagnosis by clinical and epidemiological data with Bartonella henselae is often advisable. The authors report the case of a boy aged 2 years and 9 months with 16-day history of daily fever accompanied by intermittent abdominal pain. Physical examination was unremarkable. Abdominal ultrasound performed in the initial work up was unrevealing, but an abdominal CT that was performed afterwards disclosed multiple hypoattenuating hepatic images compatible with the diagnosis of micro abscesses. Initial antibiotic regimen included cefotaxime, metronidazole, and oxacillin. Due to the epidemiology of close contact with kittens, diagnosis of CSD was considered and confirmed by serologic tests. Therefore, the initial antibiotics were replaced by clarithromycin orally for 14 days followed by fever defervescence and clinical improvement. The authors call attention to this uncommon diagnosis in a child presenting with FUO and multiple hepatic images suggestive of micro abscesses.

Unfortunately, there is confusion among the medical community regarding the management of amoebic liver abscess (ALA). Therapeutic options range from simple pharmacotherapy to use of interventions like a needle or catheter aspiration under ultrasound guidance to surgical intervention. There is a plethora of thresholds for parameters such as the maximum diameter of the abscess and volume on ultrasound examination suggested by various authors to serve as a criterion to help to decide when to use which modality in these cases. To assess the outcome of patients with uncomplicated ALA treated using a conservative approach. Moreover, to identify factors associated with its failure. A prospective, observational study was carried out at a large municipal urban health care center over a period of 3-year (2011-2014) in India. Patients with uncomplicated ALA were recruited. All patients were managed with pharmacotherapy initially for a period of 72 h. Response to treatment was assessed by resolution of symptoms within the given time frame. Failure to respond was considered an indication for intervention. Needle aspiration was offered to these patients and response assessed within 72 h. Failure to respond to aspiration was considered an indication for catheter drainage. Data recorded were entered in a Microsoft Office Excel Sheet and analyzed using the SPSS version 16.0 (IBM). Sixty patients with ALA were included in the study over its duration. Forty-nine (81.67%) patients were managed conservatively, while 11 (18.33%) patients needed an intervention for relief. Patients who required intervention had deranged liver function at presentation, a larger abscess diameter (10.09 ± 2.23 vs. 6.33 ± 1.69 cm P < 0.001) and volume (399.73 ± 244.46 vs. 138.34 ± 117.85 ml, P < 0.001) compared to those who did not need it. Patients that required intervention had a longer length of hospital stay (7.1 ± 2.4 vs. 4.8 ± 0.9 days, P < 0.001). On post hoc analysis, a maximum diameter of >7.7 cm was found to be the optimal criterion to predict the need of intervention in cases of ALA. A conservative approach is effective in the management of ALA for a majority of patients. Failure of conservative management was predicted by the size of the abscess (maximum diameter >7.7 cm). Even in the cases of failure, a gradual step-up with interventions was found to be safe and effective.

Hematoma or abscess of the liver ligaments is extremely rare, and hematoma of the falciform ligament has been sporadically reported. We report the case of a 70-year-old female who presented with a three-day history of right upper quadrant abdominal pain, fever and nausea. With a preoperative diagnosis of probable perforated acalculous cholecystitis, the patient underwent emergency surgery. Hematoma of the falciform ligament was found. Wide excision of the falciform ligament including the hematoma with abscess was performed. Although pathology of the falciform ligament is rare, it should be included in the differential diagnosis of acute abdomen, especially in the case of antiaggregant drug usage.

There are no published abattoir bovine hepatic lesion prevalence studies in cattle in Rwanda. This study estimated that 12.3% of the livers (n=4751) examined at Nyabugogo slaughterhouse in Kigali were condemned. Condemnation prejudiced the nation of 3492.00kg of meat with attendant economic losses of US$8932.40 during the study period. Risk factors for these lesions were also assessed. Male and female animals from 11 districts were used in this study. Hepatic lesions were higher in females (14.6%; n=1494) than in males (11.1%; n=3257). About 78.7% of the condemnations were due to fascioliasis, followed by abscesses (5.7%), hepatitis (5.3%), cirrhosis (4%) and other lesions (6.3%). Female animal livers showed more fascioliasis and abscesses (82.2% and 9.5%) than male animal livers (73.3% and 3.3%). The highest rate of condemnation was observed from Kayonza (40.2%; n=413) and the least was from Gakenke district (0.9%; n=1031). Cattle from the Eastern Province showed significantly (P<0.05) higher prevalence of condemnations (26.8%) than the rest of the provinces. Liver specimens of animals below 3 years and above 6 years of age had a significantly higher (P<0.05) condemnation rate (14.4%) (n=3000 and n=769) than the 3-6year age-group at 4.1% (n=982). We conclude that fascioliasis was responsible for a significant proportion of the liver condemnations at Nyabugogo slaughterhouse. Being a zoonosis, we recommend an epidemio-surveillance, implementation of control measures and anthelmintic resistance investigation for fascioliasis in Rwanda. Copyright © 2016 Elsevier B.V.

Liver fungal infections: an overview of the etiology and epidemiology in patients affected or not affected by oncohematologic malignancies

2018-01-01

Fungal infections of the liver, most commonly caused by Candida spp., often occur in patients with hematologic malignancies treated with chemotherapy. Colonization of the gastrointestinal tract is thought to be the main origin of dissemination of Candida; mucositis and neutropenia facilitate the spread of Candida from the gastrointestinal tract to the liver. Hepatic involvement due to other fungi is a less common infectious complication in this setting. Fungal infections represent a less common cause of hepatic abscesses in non-oncohematologic population and the trend appears to be decreasing in recent years. Understanding of the etiology and epidemiology of fungal infections of the liver is indicated for an appropriate antimicrobial therapy and an overall optimal management of fungal liver infections.

The left gastric artery (LGA) is commonly severed when the gastric tube is made for esophageal reconstruction. Sacrifice of the LGA can cause liver ischemic necrosis in patients with an aberrant left hepatic artery (ALHA) arising from the LGA. We experienced a case of life-threatening hepatic abscess after severing the ALHA. Therefore, the purpose of this study is to evaluate clinical outcomes of severing the ALHA. We retrospectively enrolled 176 consecutive patients who underwent esophagectomy with gastric tube reconstruction. They were classified into the ALHA (N = 16, 9.1%) and non-ALHA (N = 160, 90.9%) groups. Univariate analysis was performed to compare the clinicopathological variables. Long-term survival was analyzed using the Kaplan-Meier method in matched pair case-control analysis. The postoperative morbidities were not statistically different between the two groups, although serum alanine aminotransferase levels on postoperative days 1 and 3 were significantly higher in the ALHA group (36 IU/L, 14-515; 32 IU/L, 13-295) than in the non-ALHA group (24 IU/L, 8-163; 19 IU/L, 6-180), respectively (p = 0.0055; p = 0.0073). Overall survival was not statistically different between the two groups (p = 0.26). Severe hepatic abscess occurred in 6.3% of the patients with the ALHA after esophagectomy, even though the results presented here found no statistical differences in morbidity or mortality with or without the ALHA. Surgeons should probably attempt to preserve the ALHA especially in patients with altered liver function while making a gastric tube for esophageal reconstruction.

Subphrenic and Pleural Abscess Due to Spilled Gallstones

Varker, Kimberly A.; Zaydfudim, Victor; McKee, Jason

2006-01-01

Background: A 70-year-old male approximately 3 years after laparoscopic cholecystectomy presented to his primary care physician with a 4-month history of generalized malaise. Methods: A workup included magnetic resonance imaging that revealed a perihepatic abscess. The patient underwent ultrasound-guided drainage, with the removal of 1400 mL of purulent fluid and placement of 2 drains. Computed tomographic scanning showed resolution, and he was discharged home on oral antibiotics. At 2-month follow-up, the patient was asymptomatic, denying any constitutional symptoms. However, abdominal computed tomographic scanning revealed recurrence of the abscess, which measured approximately 18x9x7.5 cm, with mass effect on the liver. The patient was placed on intravenous antibiotics and scheduled for operative drainage. The abdomen was entered with a right subcostal incision, and 900 mL of purulent fluid was drained. We also noted abscess erosion through the inferolateral aspect of the right diaphragm into the pleural space. The pleural abscess was loculated and isolated from the lung parenchyma. Palpation within the abscess cavity revealed 9 large gallstones. Following copious irrigation and debridement of necrotic tissue, 3 drains were placed and the incision was closed. Results: The patient had an uneventful recovery and was discharged home on postoperative day number 6. Follow-up imaging at 3 months demonstrated resolution of the collection. Conclusion: Spillage of gallstones is a complication of laparoscopic cholecystectomy, occurring in 6% to 16% of all cases. Retained stones rarely result in a problem, but when complications arise, aggressive surgical intervention is usually necessary. PMID:16709371

There have been no large-scale population-based studies to estimate the subsequent risk of primary liver cancer (PLC) among patients with pyogenic liver abscess (PLA). This study aimed to provide relevant data. The Taiwan Longitudinal Health Insurance Database for the years 2000 and 2005 was used. The PLA group were adult inpatients who were newly diagnosed with PLA from 2000 to 2008. The control group was randomly selected and matched with the PLA group in terms of age, sex, and date in which medical treatment was sought other than for PLA. There were 1,987 patients each in the PLA and control groups. In total, 56 had PLC, 48 (2.4%, 601.5 per 100,000 person-years) from the PLA group, and 8 from the control group. After adjusting for potential covariates, the hazard ratio of PLC for the PLA group was 3.4 times that of the control group (95% confidence interval = 1.6-7.3, p <0.001). The PLC risk for the PLA group was significantly higher within the first year after PLA diagnosis (hazard ratio: 35.4) as compared with the control group and became insignificant (hazard ratio: 2.0, 95% confidence interval = 0.8-4.9) more than one year after PLA diagnosis. Patients with PLA have a higher rate of PLC than matched controls, especially within the first year after the diagnosis of PLA, suggesting PLA is a warning sign for PLC.

PurposeThe purpose of this study was to evaluate need for antibiotic prophylaxis for radiofrequency ablation (RFA) of liver tumors in patients with no significant co-existing risk factors for infection.Materials and MethodsFrom January 2004 to September 2013, 83 patients underwent 123 percutaneous RFA procedures for total of 152 hepatocellular carcinoma (HCC) lesions. None of the patients had pre-existing biliary enteric anastomosis (BEA) or any biliary tract abnormality predisposing to ascending biliary infection or uncontrolled diabetes mellitus. No pre- or post-procedure antibiotic prophylaxis was provided for 121 procedures. Data for potential risk factors were reviewed retrospectively and analyzed for the frequency ofmore » infectious complications, including abscess formation.ResultsOne patient (1/121 (0.8 %) RFA sessions) developed a large segment 5 liver abscess/infected biloma communicating with the gallbladder 7 weeks after the procedure, successfully treated over 10 weeks with IV and PO antibiotic therapy and percutaneous catheter drainage. This patient did not receive any antibiotics prior to RFA. During the procedure, there was inadvertent placement of RFA probe tines into the gallbladder. No other infectious complications were documented.ConclusionThese data suggest that the routine use of prophylactic antibiotics for liver RFA is not necessary in majority of the patients undergoing liver ablation for HCC and could be limited to patients with high-risk factors such as the presence of BEA or other biliary abnormalities, uncontrolled diabetes mellitus, and large centrally located tumors in close proximity to central bile ducts. Larger randomized studies are needed to confirm this hypothesis.« less

We present the case of a 49-year-old woman, with previous clinical antecedents of recent hepatic metastasis, who was admitted to the ICU due to respiratory failure and hemodynamic instability. She was found to have purulent pericarditis complicated by pericardial tamponade and pleural effusion, as well as surgical site infection, which was the origin of the disease. Cultures of the surgical wound and the pericardial effusion were positive for Enterococcus faecalis and Escherichia coli. A pericardial tap was performed and the intra-abdominal abscess was surgically drained. Pleural effusion was also evacuated. She received antibiotic treatment and recovered successfully. The only after-effect was a well-tolerated effusive-constrictive pericarditis. PMID:24872819

1984-06-01

The contrast-enhancing properties of iron (Fe) and deferoxamine (DFO) in abscess imaging with Ga-67 citrate were compared in rats bearing turpentine-induced abscesses. Iron administration shifted Ga-67 from plasma into tissues such as muscle and fat. As a result, the abscess-to-plasma ratio increased whereas the abscess-to-muscle ratio decreased. DFO enhanced the abscess-to-muscle and abscess-to-plasma ratios by increasing urinary Ga-67 excretion. The authors conclude that abscess imaging with Ga-67 citrate may be improved by administration of (a) Fe for detection of abscesses masked by blood activity, or (b) DFO for detection of abscesses surrounded by muscle tissue.

Liver Disease in Sri Lanka.

Liver disease in Sri Lanka is mainly due to alcoholic liver disease and nonalcoholic fatty liver disease. In contrast to other South Asian countries, the prevalence of hepatitis B and C is low in Sri Lanka and prevalence of hepatitis A is intermediate. The few reported cases of hepatitis E in Sri Lanka are mainly in people who have traveled to neighboring South Asian countries. Wilson's disease, autoimmune hepatitis, hemochromatosis, drug-induced liver disease, and primary biliary cirrhosis are recognized causes of liver disease in Sri Lanka. Pyogenic and amebic liver abscesses and dengue infection are the other causes of liver disease. Some of the commonly used plants as traditional herbal medicine in Sri Lanka have been shown to have deleterious effects on the liver in animal studies. Considering the high popularity of traditional herbal medicine in the country, it is likely that herbal medicine is an etiological factor for liver disease in Sri Lanka, but no published data are available.

Abstract Rationale: Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. Patient concerns: We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. Diagnoses: Retroperitoneal metastasis of hepatic phase fascioliasis. Interventions: The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. Outcomes: After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. Lessons: To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

Ferritin L (FTL) and Ferritin H (FTH) subunits are responsible for intercellular iron storage. We previously reported increasing amounts of liver cytoplasmic and nuclear iron content during acute phase response (APR). Aim of the present study is to demonstrate intracellular localization of ferritin subunits in liver compared with extra hepatic organs of rat under physiological and acute phase conditions. Rats were administered turpentine-oil (TO) intramuscularly to induce a sterile abscess (acute-phase-model) and sacrificed at different time points. Immunohistochemistry was performed utilizing horse-reddish-peroxidise conjugated secondary antibody on 4μm thick section. Liver cytoplasmic and nuclear protein were used for Western blot analysis. By means of immunohistology, FTL was detected in cytoplasm while a strong nuclear positivity for FTH was evident in the liver. Similarly, in heart, spleen and brain FTL was detected mainly in the cytoplasm while FTH demonstrated intense nuclear and a weak cytoplasmic expression. Western blot analysis of cytoplasmic and nuclear fractions from liver, heart, spleen and brain further confirmed mainly cytoplasmic expression of FTL in contrast to the nuclear and cytoplasmic expression of FTH. The data presented demonstrate the differential localization of FTL and FTH within hepatic and extra hepatic organs being FTL predominantly in the cytoplasm while FTH predominantly in nucleus.

We describe the first two multifocal invasive infections due to Klebsiella pneumoniae recently observed in Switzerland. Phenotypic (MIC assays and string test) and molecular analyses (PCR/Sequencing for bla, virulence factor genes and whole genome sequencing for one strain) were performed to characterize the causative K. pneumoniae isolates. Both K. pneumoniae isolates (Kp1 and Kp2) were pan-susceptible to antibiotics and produced narrow-spectrum SHV β-lactamases. However, only Kp1 was string test positive. Kp1 was of ST380 and caused liver abscess as well as pneumonia and orbital phlegmon in an Eritrean patient. It belonged to the hypervirulent capsular serotype K2 and harboured the classic virulence-associated rmpA and aerobactin genes, fulfilling both the clinical and microbiological definitions for an invasive K. pneumoniae syndrome. Kp2 was of ST1043 and caused both liver abscess and endocarditis in a Swiss patient. Moreover, it did not possess the classic virulence-associated genes. Whole genome sequencing identified less well-known virulence factors in Kp2 that might have contributed to its virulence. Among these there were genes important for intestinal colonization and/or invasion, such as genes involved in adhesion (e.g., fimABCD and mrkABCD), regulation of capsule polysaccharide biosynthesis (e.g., evgS-evgA), as well as iron uptake (iroN), energy conversion, and metabolism. This report confirms the continuous dissemination of hypervirulent K. pneumoniae strains among patients of non-Asian descent in Europe. Moreover, it highlights the genetic background of an atypical hypervirulent K. pneumoniae causing a severe invasive infection despite not possessing the classical virulence characteristics of hypermucoviscous strains.

Approach to Clinical Syndrome of Jaundice and Encephalopathy in Tropics

A large number of patients present with jaundice and encephalopathy in tropical country like India and acute liver failure is the usual cause. Clinical presentation like ALF is also a complication of many tropical infections, and these conditions may mimic ALF but may have subtle differences from ALF. Moreover, what hepatologists see as acute liver failure in tropics is different from what is commonly described in Western Textbooks. Paracetamol overdose, which is possibly the commonest cause of ALF in UK and USA, is hardly ever seen in India. Most common etiology here is viral hepatitis (hepatitis E > hepatitis B> hepatitis A). Apart from ALF, one may also come across subacute hepatic failure (SAHF) as well as acute-on-chronic liver failure (ACLF) due to viral hepatitis. Interestingly, a host of other conditions can mimic ALF because clinical presentation in these conditions can be dominated by jaundice and encephalopathy. Malarial hepatopathy is possibly the best-known condition out of these and is not an uncommon manifestation of severe malaria. A similar presentation can also be seen in other common infections in tropics such as dengue fever, typhoid fever, leptospirosis, scrub typhus, amoebic liver abscesses, tuberculosis and other bacterial and fungal infections with or without human immunodeficiency virus (HIV) related disease. In many of these conditions, liver failure may not be underlying pathophysiology. Some pregnancy related liver diseases could also present with jaundice and encephalopathy. This review summarizes the commonly seen presentations in tropical country like India, where jaundice and encephalopathy dominate the clinical picture. PMID:26041951

TNFα-Mediated Liver Destruction by Kupffer Cells and Ly6Chi Monocytes during Entamoeba histolytica Infection

Amebic liver abscess (ALA) is a focal destruction of liver tissue due to infection by the protozoan parasite Entamoeba histolytica (E. histolytica). Host tissue damage is attributed mainly to parasite pathogenicity factors, but massive early accumulation of mononuclear cells, including neutrophils, inflammatory monocytes and macrophages, at the site of infection raises the question of whether these cells also contribute to tissue damage. Using highly selective depletion strategies and cell-specific knockout mice, the relative contribution of innate immune cell populations to liver destruction during amebic infection was investigated. Neutrophils were not required for amebic infection nor did they appear to be substantially involved in tissue damage. In contrast, Kupffer cells and inflammatory monocytes contributed substantially to liver destruction during ALA, and tissue damage was mediated primarily by TNFα. These data indicate that besides direct antiparasitic drugs, modulating innate immune responses may potentially be beneficial in limiting ALA pathogenesis. PMID:23300453

Bilious pleural effusion is an extremely rare condition associated with liver diseases, subphrenic or subhepatic abscess formation, biliary peritonitis, and invasive procedures (i.e., percutaneous biliary drainage or liver biopsy). The current diagnostic test is based on the measurement of the ratio of pleural total bilirubin to serum total bilirubin, which is greater than 1 in patients with bilious pleural effusion. Given the low incidence of bilious pleural effusion, the precise diagnostic yield of this ratio based test has not been evaluated. We retrospectively reviewed the medical records of our institution and searched the PubMed database for reports of bilious pleural effusion. We identified a total of 12 cases of bilious pleural effusion (9 from 8 Pubmed reports and 3 from our institutional records). The factors causing this condition were broadly classified into three categories based on the pathophysiology: 1) liver diseases (echinococcosis, tuberculosis and amebiasis); 2) subhepatic/subphrenic abscess or biliary peritonitis, with or without biliary tract obstruction; and 3) iatrogenic disease after percutaneous biliary drainage and/or liver biopsy. The sensitivity of detection was 76.9% when the ratio of pleural total bilirubin to serum total bilirubin was greater than 1. The sensitivity increased to 100% when a combination test including pleural glycoholic acid was adopted. This study demonstrates the high diagnostic yield for bilious pleural effusion using a combination of two test criteria; a ratio of pleural total bilirubin to serum total bilirubin greater than 1 and the presence of pleural glycoholic acid.

Visceral larva migrans, caused by Toxocara canis and Toxocara cati, has emerged as a significant cause of eosinophilic liver abscess (ELA). Differentiation of ELA associated with toxocariasis (ELA-T) from metastasis or primary liver malignancy is sometimes difficult. However, the role of albendazole treatment remains uncertain in this condition. The aim of this study was to evaluate whether albendazole can enhance the radiologic resolution of ELA-T. We retrospectively reviewed the medical records of the patients diagnosed with ELA-T at our institution between January 2008 and December 2011. ELA-T was diagnosed based on the imaging findings on computed tomography or magnetic resonance imaging and the presence of positive serum IgG antibody for Toxocara canis. Among a total of 163 patients, 32 patients received albendazole (albendazole group) and 131 did not (control group). Baseline characteristics and fate of liver nodules were compared between the two groups. Baseline characteristics (age, sex, number and maximal size of lesions, eosinophil count) were similar between the two groups. Median duration for achieving radiologic resolution in the albendazole group was significantly shorter than in the control group (207 days [range 186-228] vs. 302 days [range 224-380], p=0.023). In Cox regression analysis of the cumulative rates of radiologic resolution, the hazard ratio for albendazole treatment was 1.99 (95% confidence interval, 1.22-3.23). Radiologic resolution of ELA-T can be accelerated with albendazole treatment. Hence, inconvenience associated with long-term follow-up and unnecessary worries among patients can be eliminated with albendazole treatment.

A 16-year-old spayed female American Shorthair cat was presented with lethargy, anorexia, and wamble. Physical and blood examination did not reveal any remarkable findings. Abdominal ultrasonography identified the presence of a localized anechoic structure with a thick wall in contact with the small intestine and adjacent to the liver. Ultrasound-guided fine-needle aspiration of the structure revealed fluid containing numerous cocci and neutrophils. Two days after antibiotic treatment, exploratory laparotomy was performed and the content of the structure was removed before multiple lavages. The pathological and bacteriological examination results supported a confirmatory diagnosis of pancreatic abscess due to Staphylococcus aureus infection, making this the first such report in a cat. The cat remained healthy thereafter with no disease recurrence.

Giant cystic pheochromocytoma is a rare neuroendocrine tumor. The possibility of cystic pheochromocytoma should be considered for any peri-adrenal mass even in absence of characteristic symptoms and negative biochemical analysis. The key in the management of a case of cystic pheochromocytoma is the preoperative suspicion and the intraoperative crisis management.

To evaluate the healing process of rat traumatic liver lesion corrected with the use of 2-octyl cyanoacrylate adhesive, compared to the use of biologically absorbable chromed catgut thread suture. Thirty mail adult rats were divided into two groups (15 per group) according to the used method for liver lesion correction as follows: adhesive group (AG), and catgut group (CG); each group being divided into three subsets of five animals (7th, 14th, and 21st day), respectively, according to post-surgery evaluation. All animals were submitted to homogeneous lesion applying synthetic bonding to AG and using chromed catgut suture to CG for lesion correction. Macroscopic and microscopic parameters of healing processes were evaluated. Both groups of animals showed excellent abdominal wall healing, with no evidence of infection, and no abdominal cavity peritonitis or abscess. The presence of adherence was observed in both groups with no statistically significant difference. As to macroscopic evaluation, there was statistically significant difference with respect to specific factors of clinical inflammation (ischemic inflammation and giant celular inflammatory reaction) between animals evaluated on the 10th day (ischemic necrosis and giant cellular inflammatory reaction) among animals evaluated on the 14th day (A14 versus C14). Applying 2-octyl-cyanoacrylate adhesive for correcting rat liver lesion does not change healing process when compared to the use of chromed catgut stitch.

Previously, we reported that wild eastern box turtles (Terrapene carolina carolina) with aural abscesses contained higher body burdens of organochlorine (OC) compounds than those without the lesion. This lesion in captive chelonians is associated with turtles that are fed diets deficient in vitamin A. To examine the pathophysiology of this lesion and evaluate the relationship between OC burdens and vitamin A metabolism, we maintained red-eared sliders (Trachemys scripta elegans) under different conditions of OC exposure and dietary vitamin A concentrations from August 2005 to February 2006. Dietary vitamin A concentration (0 or 5 international units/g in the diet) and OC exposure (no OC compound or the mixture of 2 mg/kg chlordane, 0.25 mg/kg aroclor, and 1 mg/kg lindane) did not affect histologic score based on degree of squamous metaplasia of the tympanic epithelium or levels of plasma or liver vitamin A among the study groups. The results of this study suggest that 6 mo of exposure to the selected OC compounds, or similar duration of reduced dietary vitamin A concentrations do not influence the formation of squamous metaplasia and aural abscesses in red-eared sliders. Further studies are required to determine whether the duration of the experiment was insufficient, the OC compounds selected were inappropriate, the dosing was incorrect, and whether there are other unknown mechanisms causing the reported association between OC exposure and aural abscesses seen in eastern box turtles.

The seroepidemiology of Leptospira infection in patients suffering from liver disease has been poorly studied. Information about risk factors associated with infection in liver disease patients may help in the optimal planning of preventive measures. We sought to determine the association of Leptospira IgG seroprevalence and patients with liver diseases, and to determine the characteristics of the patients with Leptospira exposure. We performed a case-control study of 75 patients suffering from liver diseases and 150 age- and gender-matched control subjects. Diagnoses of liver disease included liver cirrhosis, steatosis, chronic hepatitis, acute hepatitis, and amoebic liver abscess. Sera of participants were analyzed for the presence of anti- Leptospira IgG antibodies using a commercially available enzyme immunoassay. Anti-Leptospira IgG antibodies were found in 17 (22.7%) of 75 patients and in 15 (10.0%) of 150 control subjects (OR = 2.32; 95% CI: 1.09-4.94; P=0.03). This is the first age- and gender-matched case control study about Leptospira seroprevalence in patients with liver diseases. Results indicate that Leptospira infection is associated with chronic and acute liver diseases. Results warrants for additional studies on the role of Leptospira exposure in chronic liver disease.

Pannonibacter phragmitetus is a bioremediation reagent for the detoxification of heavy metals and polycyclic aromatic compounds (PAHs) while it rarely infects healthy populations. However, infection by the opportunistic pathogen P. phragmitetus complicates diagnosis and treatments, and poses a serious threat to immunocompromised patients owing to its multidrug resistance. Unfortunately, genome features, antimicrobial resistance, and virulence potentials in P. phragmitetus have not been reported before. A predominant colony (31801) was isolated from a liver abscess patient, indicating that it accounted for the infection. To investigate its infection mechanism(s) in depth, we sequenced this bacterial genome and tested its antimicrobial resistance. Average nucleotide identity (ANI) analysis assigned the bacterium to the species P. phragmitetus (ANI, >95%). Comparative genomics analyses among Pannonibacter spp. representing the different living niches were used to describe the Pannonibacter pan-genomes and to examine virulence factors, prophages, CRISPR arrays, and genomic islands. Pannonibacter phragmitetus 31801 consisted of one chromosome and one plasmid, while the plasmid was absent in other Pannonibacter isolates. Pannonibacter phragmitetus 31801 may have a great infection potential because a lot of genes encoding toxins, flagellum formation, iron uptake, and virulence factor secretion systems in its genome. Moreover, the genome has 24 genomic islands and 2 prophages. A combination of antimicrobial susceptibility tests and the detailed antibiotic resistance gene analysis provide useful information about the drug resistance mechanisms and therefore can be used to guide the treatment strategy for the bacterial infection. © 2017 The Authors.

Acute ruminal acidosis is a metabolic status defined by decreased blood pH and bicarbonate, caused by overproduction of ruminal D-lactate. It will appear when animals ingest excessive amount of nonstructural carbohydrates with low neutral detergent fiber. Animals will show ruminal hypotony/atony with hydrorumen and a typical parakeratosis-rumenitis liver abscess complex, associated with a plethora of systemic manifestations such as diarrhea and dehydration, liver abscesses, infections of the lung, the heart, and/or the kidney, and laminitis, as well as neurologic symptoms due to both cerebrocortical necrosis and the direct effect of D-lactate on neurons. In feedlots, warning signs include decrease in chewing activity, weight, and dry matter intake and increase in laminitis and diarrhea prevalence. The prognosis is quite variable. Treatment will be based on the control of systemic acidosis and dehydration. Prevention is the most important tool and will require normalization of ruminal pH and microbiota. Appropriate feeding strategies are essential and involve changing the dietary composition to increase neutral detergent fiber content and greater particle size and length. Appropriate grain processing can control the fermentation rate while additives such as prebiotics or probiotics can help to stabilize the ruminal environment. Immunization against producers of D-lactate is being explored.

Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. Retroperitoneal metastasis of hepatic phase fascioliasis. The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

Abstract Delayed-onset primary liver cancer (PLC) including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) in patients with pyogenic liver abscess (PLA) is not common. The relationship between PLA and delayed-onset PLC is unclear. We investigated the association in a nationwide cohort study. From Taiwan National Health Insurance claims data, a cohort of 17,531 patients with PLA was generated after excluding patients with a history of cancer (n = 2034) and those diagnosed with PLC (n = 572) and other cancers (n = 627) within 1 year of a diagnosis of PLA. An age-, sex-, index year-, and diabetes mellitus (DM)-matched control cohort of 70,124 persons without PLA was selected from the same dataset. Both cohorts were followed up until the end of 2011. The risk of PLC was estimated for both cohorts. The incidence of PLC was nearly 2-fold greater in the PLA group than in the control cohort (29.3 per 10,000 person-years vs. 16.2 per 10,000 person-years). The incidences of HCC and ICC were 1.5- (22.1 per 10,000 person-years vs. 15.0 per 10,000 person-years) and 11-fold greater (6.73 per 10,000 person-years vs. 0.62 per 10,000 person-years), respectively, in the PLA group than in the control cohort. The PLA cohort also had high risks of PLC (adjusted hazard ratio [aHR] = 1.56; 95% confidence interval [CI] = 1.35–1.81), HCC (aHR = 1.34; 95% CI = 1.15–1.57), and ICC (aHR = 6.94; 95% CI = 4.23–11.57). In conclusion, in this nationwide cohort study, PLA increased the risk of delayed-onset PLC. PMID:28834881

Fascioliasis is an often-neglected zoonotic disease and currently is an emerging infection in Iraq. Fascioliasis has two distinct phases, an acute phase, exhibiting the hepatic migratory stage of the fluke's life cycle, and a chronic biliary phase manifested with the presence of the parasite in the bile ducts through hepatic tissue. The incidence of Fascioliasis in Sulaimaniyah governorate was unexpected observation. We believe that shedding light on this disease in our locality will increase our physician awareness and experience in early detection, treatment in order to avoid unnecessary surgeries. We retrospectively evaluated this disease in terms of the demographic features, clinical presentations, and managements by reviewing the medical records of 18 patients, who were admitted to the Sulaimani Teaching Hospital and Kurdistan Centre for Gastroenterology and Hepatology. Patients were complained from hepatobiliary and/or upper gastrointestinal symptoms and diagnosed accidentally with Fascioliasis during hepatobiliary surgeries and ERCP by direct visualization of the flukes and stone analysis. Elevated liver enzymes, white blood cells count and eosinophilia were notable laboratory indices. The dilated CBD, gallstones, liver cysts and abscess were found common in radiological images. Fascioliasis diagnosed during conventional surgical CBD exploration and choledochodoudenostomy, open cholecystectomy, surgical drainage of liver abscess, ERCP and during gallstone analysis. Fascioliasis is indeed an emerging disease in our locality, but it is often underestimated and ignored. We recommend the differential diagnosis of patients suffering from Rt. Hypochondrial pain, fever and eosinophilia. The watercress ingestion was a common factor in patient's history.

The purpose of this study was to identify risk factors for abscess formation in acute bacterial prostatitis, and to compare treatment outcomes between abscess group and non-abscess group. This is a multicenter, retrospective cohort study. All patients suspected of having an acute prostatic infection underwent computed tomography or transrectal ultrasonography to discriminate acute prostatic abscesses from acute prostatitis without abscess formation. A total of 31 prostate abscesses were reviewed among 142 patients with acute prostatitis. Univariate analysis revealed that symptom duration, diabetes mellitus and voiding disturbance were predisposing factors for abscess formation in acute prostatitis. However, diabetes mellitus was not related to prostate abscess in multivariate analysis. Patients with abscesses <20 mm in size did not undergo surgery and were cured without any complications. In contrast, patients with abscesses >20 mm who underwent transurethral resection had a shorter duration of antibiotic treatment than did those who did not have surgery. Regardless of surgical treatment, both the length of hospital stay and antibiotic treatment were longer in patients with prostatic abscesses than they were in those without abscesses. However, the incidence of septic shock was not different between the two groups. A wide spectrum of microorganisms was responsible for prostate abscesses. In contrast, Escherichia coli was the predominant organism responsible for acute prostatitis without abscess. Imaging studies should be considered when patients with acute prostatitis have delayed treatment and signs of voiding disturbance. Early diagnosis is beneficial because prostatic abscesses require prolonged treatment protocols, or even require surgical drainage. Surgical drainage procedures such as transurethral resection of the prostate were not necessary in all patients with prostate abscesses. However, surgical intervention may have potential merits that reduce the antibiotic exposure period and enhance voiding function in patients with prostatic abscess.

Liver metastasis is an important prognostic factor in colorectal cancer. The efficacy of resection of metastatic lesions in liver metastasis of colorectal cancer is also widely recognized. However, studies on treatment methods of unresectable cases have not been sufficient and obtaining complete remission (CR) for liver metastasis is rare with chemotherapy. Selection of reliable chemotherapy for unresectable liver metastasis is an urgent necessity. The usefulness of oxaliplatin, 5-flurouracil and leucovorin combination therapy (FOLFOX) has recently been reported, but CR of liver metastasis is rare. The current status and new therapeutic significance of FOLFOX therapy are discussed based on the literature of colorectal cancer chemotherapy to date, and the clinical experience in which we obtained CR for liver metastasis is reported. The patient had stage IV rectal cancer, perforative peritonitis, pelvic abscess and simultaneous multiple liver metastasis. The patient underwent an emergency operation using the Hartmann's procedure. Liver metastasis is considered to be a prognostic factor and FOLFOX was selected as the postoperative chemotherapy, CR of the liver metastasis was obtained. FOLFOX was suggested to have new clinical significance in oncologic emergencies against unresectable liver metastasis in colorectal cancer and should serve as adjuvant chemotherapy that will contribute to improvement of treatment results.

Staphylococcus aureus (SA) breast abscesses are a complication of the postpartum period. Risk factors for postpartum SA breast abscesses are poorly defined, and literature is conflicting. Whether risk factors for methicillin-resistant SA (MRSA) and methicillin-susceptible SA (MSSA) infections differ is unknown. We describe novel risk factors associated with postpartum breast abscesses and the changing epidemiology of this infection. We conducted a cohort study with a nested case-control study (n = 216) involving all patients with culture-confirmed SA breast abscess among >30 000 deliveries at our academic tertiary care center from 2003 through 2010. Data were collected from hospital databases and through abstraction from medical records. All SA cases were compared with both nested controls and full cohort controls. A subanalysis was completed to determine whether risk factors for MSSA and MRSA breast abscess differ. Univariate analysis was completed using Student's t test, Wilcoxon rank-sum test, and analysis of variance, as appropriate. A multivariable stepwise logistic regression was used to determine final adjusted results for both the case-control and the cohort analyses. Fifty-four cases of culture-confirmed abscess were identified: 30 MRSA and 24 MSSA. Risk factors for postpartum SA breast abscess in multivariable analysis include in-hospital identification of a mother having difficulty breastfeeding (odds ratio, 5.00) and being a mother employed outside the home (odds ratio, 2.74). Risk factors did not differ between patients who developed MRSA and MSSA infections. MRSA is an increasingly important pathogen in postpartum women; risk factors for postpartum SA breast abscess have not changed with the advent of community-associated MRSA.

Background/aim: Our aim was to interpret the effects of deep neck space abscesses on the adjacent carotid artery according to abscess location, as well as to determine narrowing by calculating the mean stenosis ratios.Materials and methods: Neck computed tomography scans and clinical data of 45 children with neck abscesses were evaluated retrospectively for abscess location and internal carotid artery narrowing. The lumen areas of the carotid arteries were measured from standard levels, and stenosis ratios were calculated with two different techniques. The mean stenosis ratios of each group according to abscess location were then compared with the control group.Results: Among the 45 abscesses included in the study, 51.1% (n = 23/45) were located in the peritonsillar region, 37.8% (n = 17/45) were located in the parapharyngeal-lateral retropharyngeal space, and 11.1% (n = 5/45) were in the midline retropharyngeal space. We found a statistically significant difference between the mean stenosis ratios of the ipsilateral side of the parapharyngeal-lateral retropharyngeal abscesses and the control group (P < 0.01).Conclusion: The children with parapharyngeal-lateral retropharyngeal abscesses all had narrowing in the adjacent carotid lumen to some degree. Although most of the patients had no clinical symptoms, radiologists have to be aware of this arterial complication to prevent further progress and fatal complications.

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. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Few studies exist to guide the treatment approach to intra-abdominal abscesses in Crohn disease, which can include antimicrobials alone or in conjunction with percutaneous drainage or surgery. The primary aim of this study is to review outcomes from different treatment approaches to intra-abdominal abscess in Crohn disease. Medical records were reviewed for patients admitted to the University of Michigan health care system with Crohn disease and intra-abdominal abscess over a 4-year period. Outcomes were compared among medical and interventional approaches. The χ 2 test was used to test for statistical significance. Of the 33 patients included, 13 were in the medical group and 20 were in the interventional group. Abscess recurrence/nonresolution occurred in 31% of patients in the medical group and 25% of patients in the interventional group ( P = .7). In this study, there was no significant difference in outcome between medical and interventional therapy for intra-abdominal abscess in Crohn disease.

There are sporadic reports in the literature in which radiologic liver and lung lesions found incidentally during follow-up metastatic surveillance were shown to be caused by toxocariasis. The objective of the work discussed in this report was to identify common clinical and histopathological features of toxocariasis resembling metastatic nodules in five patients with gastrointestinal cancer. We retrospectively analyzed clinical features of five gastrointestinal cancer patients with liver or lung nodules mimicking metastasis. Serologic tests for parasitic infestations and pathologic examinations were performed. All five patients were males and three patients had gastric cancer and two had colorectal cancer. All the cases of toxocariasis were confirmed serologically. On follow-up imaging, the lesions improved or resolved, suggestive of the phenomenon of visceral larva migrans. In two patients, liver biopsy was performed and showed eosinophilic abscess. Serologic tests and liver or lung biopsy should be performed aggressively to exclude toxocariasis when patients with underlying gastrointestinal cancer present with hepatic or pulmonary nodules associated with eosinophilia, particularly if the patients have a clinical history of raw animal liver ingestion. Curative surgical intervention should not be excluded just because of multiple nodules in the liver or the lungs.

Ruminal Acidosis in Feedlot: From Aetiology to Prevention

Hernández, Joaquín; Benedito, José Luis; Abuelo, Angel; Castillo, Cristina

2014-01-01

Acute ruminal acidosis is a metabolic status defined by decreased blood pH and bicarbonate, caused by overproduction of ruminal D-lactate. It will appear when animals ingest excessive amount of nonstructural carbohydrates with low neutral detergent fiber. Animals will show ruminal hypotony/atony with hydrorumen and a typical parakeratosis-rumenitis liver abscess complex, associated with a plethora of systemic manifestations such as diarrhea and dehydration, liver abscesses, infections of the lung, the heart, and/or the kidney, and laminitis, as well as neurologic symptoms due to both cerebrocortical necrosis and the direct effect of D-lactate on neurons. In feedlots, warning signs include decrease in chewing activity, weight, and dry matter intake and increase in laminitis and diarrhea prevalence. The prognosis is quite variable. Treatment will be based on the control of systemic acidosis and dehydration. Prevention is the most important tool and will require normalization of ruminal pH and microbiota. Appropriate feeding strategies are essential and involve changing the dietary composition to increase neutral detergent fiber content and greater particle size and length. Appropriate grain processing can control the fermentation rate while additives such as prebiotics or probiotics can help to stabilize the ruminal environment. Immunization against producers of D-lactate is being explored. PMID:25489604

Human toxocariasis is the most prevalent helminthiasis in Korea and other industrialized countries. The clinical features of toxocariasis are diverse, according to the involved organ. Typically, Toxocara spp. infection is easily treated with 400 mg albendazole twice a day for 5 days. However, we experienced a case of recurrent toxocariasis that was refractory to this standard therapy and presented with urticaria, an uncommon symptom in toxocariasis. A 35-year-old male visited our emergency room because of abdominal pain. He had recently consumed raw cow liver (3 weeks prior to presentation). Laboratory analyses revealed eosinophilia (1,612 cells/µL) and increased total IgE (3,060 IU/mL). Chest X-ray showed multiple lung nodules in both lungs, and computed tomography revealed multiple ground-glass opacities in both lungs and multiple tiny liver abscesses. Liver biopsy revealed an eosinophilic abscess. Enzyme-linked immunosorbent assay findings for Toxocara antigens were positive (optical density, 2.140), leading to a diagnosis of toxocariasis. We initiated a 5-day treatment with albendazole and prednisolone; however, 6 days after completing the treatment, the patient again experienced urticaria and severe itching that could not be controlled by antihistamines or hydrocortisone cream. A second bout of eosinophilia suggested recurring toxocariasis, for which we prescribed a second round of albendazole. Despite an initial improvement in his symptoms, the patient returned after 6 weeks complaining of abdominal pain for 6 hours, which was reminiscent of his first attack; he also exhibited eosinophilia. Accordingly, albendazole was administered once more for an additional 3 weeks, and his symptoms resolved.

Sporadic incidence of Fascioliasis detected during Hepatobiliary procedures: A study of 18 patients from Sulaimaniyah governorate

PubMed Central

2012-01-01

Background Fascioliasis is an often-neglected zoonotic disease and currently is an emerging infection in Iraq. Fascioliasis has two distinct phases, an acute phase, exhibiting the hepatic migratory stage of the fluke’s life cycle, and a chronic biliary phase manifested with the presence of the parasite in the bile ducts through hepatic tissue. The incidence of Fascioliasis in Sulaimaniyah governorate was unexpected observation. We believe that shedding light on this disease in our locality will increase our physician awareness and experience in early detection, treatment in order to avoid unnecessary surgeries. Findings We retrospectively evaluated this disease in terms of the demographic features, clinical presentations, and managements by reviewing the medical records of 18 patients, who were admitted to the Sulaimani Teaching Hospital and Kurdistan Centre for Gastroenterology and Hepatology. Patients were complained from hepatobiliary and/or upper gastrointestinal symptoms and diagnosed accidentally with Fascioliasis during hepatobiliary surgeries and ERCP by direct visualization of the flukes and stone analysis. Elevated liver enzymes, white blood cells count and eosinophilia were notable laboratory indices. The dilated CBD, gallstones, liver cysts and abscess were found common in radiological images. Fascioliasis diagnosed during conventional surgical CBD exploration and choledochodoudenostomy, open cholecystectomy, surgical drainage of liver abscess, ERCP and during gallstone analysis. Conclusion Fascioliasis is indeed an emerging disease in our locality, but it is often underestimated and ignored. We recommend the differential diagnosis of patients suffering from Rt. Hypochondrial pain, fever and eosinophilia. The watercress ingestion was a common factor in patient’s history. PMID:23259859

A New Human 3D-Liver Model Unravels the Role of Galectins in Liver Infection by the Parasite Entamoeba histolytica

2014-01-01

Investigations of human parasitic diseases depend on the availability of appropriate in vivo animal models and ex vivo experimental systems, and are particularly difficult for pathogens whose exclusive natural hosts are humans, such as Entamoeba histolytica, the protozoan parasite responsible for amoebiasis. This common infectious human disease affects the intestine and liver. In the liver sinusoids E. histolytica crosses the endothelium and penetrates into the parenchyma, with the concomitant initiation of inflammatory foci and subsequent abscess formation. Studying factors responsible for human liver infection is hampered by the complexity of the hepatic environment and by the restrictions inherent to the use of human samples. Therefore, we built a human 3D-liver in vitro model composed of cultured liver sinusoidal endothelial cells and hepatocytes in a 3D collagen-I matrix sandwich. We determined the presence of important hepatic markers and demonstrated that the cell layers function as a biological barrier. E. histolytica invasion was assessed using wild-type strains and amoebae with altered virulence or different adhesive properties. We showed for the first time the dependence of endothelium crossing upon amoebic Gal/GalNAc lectin. The 3D-liver model enabled the molecular analysis of human cell responses, suggesting for the first time a crucial role of human galectins in parasite adhesion to the endothelial cells, which was confirmed by siRNA knockdown of galectin-1. Levels of several pro-inflammatory cytokines, including galectin-1 and -3, were highly increased upon contact of E. histolytica with the 3D-liver model. The presence of galectin-1 and -3 in the extracellular medium stimulated pro-inflammatory cytokine release, suggesting a further role for human galectins in the onset of the hepatic inflammatory response. These new findings are relevant for a better understanding of human liver infection by E. histolytica. PMID:25211477

The objective was to study the effect of rumen-escape starch and coarseness of ingredients in pelleted concentrates on performance, carcass quality and rumen wall characteristics in rosé veal calf production. Two alternative concentrates (Coarse and Slow) were compared with a traditional (Control) concentrate. Control was based on finely ground ingredients, whereas in Coarse, the same ingredients were coarsely ground resulting in a mean particle size before pelleting of 1.5 in Coarse and 0.6 mm in Control. Slow compared with Control and Coarse contained finely ground sorghum and corn instead of barley and wheat which increased the amount of rumen-escape starch to 59 compared with 22 g/kg in Control and Coarse. All concentrates had the same total starch (362 g/kg), NDF (168 g/kg), CP (154 g/kg) and DE (15.5 MJ/kg DM) content and a pellet diameter of 3.5 to 4 mm. Use of an 'indicator of starch digestibility' method gave a value of 98.6% for Control and Coarse and 91.1% for Slow (P < 0.001). A total of 57 Holstein bull calves (n = 19 per treatment) were offered one of the three concentrates ad libitum from weaning (2½ months of age) to slaughter (<10 months of age). Concentrate intake was recorded individually. Barley straw was available ad libitum but intake was not recorded. Average daily gain (1.43 kg/day), concentrate conversion efficiency (3.7 kg DM concentrate/kg gain), LW at slaughter (386 kg), carcass weight (194 kg) and EUROP conformation (3.9) were not affected by type of concentrate (P > 0.05). Papillae length and shape evaluated in atrium ruminis and the cranial part of the ventral rumen sac at slaughter were not affected by type of concentrate (P > 0.05). Rumen wall characteristics showed degrees of plaque formation (i.e., papillary aggregation), hyperaemia and necrotic areas in all treatment groups, but with no general difference between type of concentrate (P > 0.05). Incidence of liver abscesses (LAs, 16%) was not affected by type of concentrate (P > 0.05). There were no differences in performance or rumen wall characteristics between liver-abscessed and non-abscessed calves. The results show a high level of production performance with the three types of pelleted concentrates and indicates that neither the more coarse ingredients nor the additional rumen-escape starch tested, when fed ad libitum, could improve rumen wall characteristics or reduce LAs of rosé veal calves.

The hypervirulent K1 serotype Klebsiella pneumoniae is responsible for a new invasive syndrome, typically associated to hepatic abscesses with extra-hepatic complications. Initially described in Taiwan, it has significantly spread to several Asian countries and more recently to Europe and North America, thus constituting an emerging and global problem. The authors describe a case report of a 64-years-old portuguese caucasian woman without any previous diseases or epidemiological risk factors such as trips or contact with Asian products or population, diagnosed with a pyogenic liver abscess with pleural effusion caused by this hyper-virulent strain. A successful clinical cure was achieved after the etiological identification and treatment with antimicrobial therapy combined with catheter drainage. This is the first identification of hypervirulent Klebsiella pneumonia ST 23 clone in Portugal in the context of an invasive syndrome.

The authors describe a rare case of posttraumatic pseudoaneurysm of an anomaly arising right hepatic artery accompanied with arteriobiliary fistula. Treacherousness of this case was given by anomaly origin of the affected vessel. Thirty-four year old female has been treated at the author's department after sustained knife abdominal injury. Before our treatment, she was twice operated at the other hospital for haemoperitoneum and subhepatic abscess with haemobilia. The patient was transferred to the 1st department of surgery in Kosice because of septic shock, right-lobe hepatic abscess and repeated haemobilia. Selective hepatico-mesentericography revealed the cause of haemobilia. At the operation a double ligation of anomaly right hepatic artery was carried out together with closure of arteriobiliary fistula via choledochotomy. Haemobilia was not seen after surgery and the patient was discharged without any signs of liver disfunction. Repeated angiography showed closure of anomaly arising vessel.

Recurrent gastrointestinal bleeding and hepatic infarction after liver biopsy.

2014-02-21

Hepatic artery pseudoaneurysms (HAP) are rare events, particularly after liver biopsy, but can be associated with serious complications. Therefore a high suspicion is necessary for timely diagnosis and appropriate treatment. We report on a case of HAP that potentially formed after a liver biopsy in a patient with sarcoidosis. The HAP in our case was virtually undetectable initially by angiography but resulted in several complications including recurrent gastrointestinal bleeding, hemorrhagic cholecystitis and finally hepatic infarction with abscess formation until it became detectable at a size of 5-mm. The patient remains asymptomatic over a year after endovascular embolization of the HAP. In this report, we demonstrate that a small HAP can avoid detection by angiography at an early stage while being symptomatic for a prolonged course. A high clinical suspicion with a close clinical/radiological follow-up is needed in symptomatic patients with history of liver biopsy despite initial negative work up. Once diagnosed, HAP can be safely and effectively treated by endovascular embolization.

Purpose Information on the clinical features of lung abscess, which is uncommon in children, at hospitalizationis helpful to anticipate the disease course and management. There is no report concerning lung abscess in Korean children. We aimed to identify the clinical characteristics of pediatric lung abscess and compare the difference between primary and secondary abscess groups. Methods The medical records of 11 lung abscess patients (7 males and 4 females) from March 1998 to August 2011 at two university hospitals were retrospectively reviewed. The clinical characteristics, symptoms, underlying disease, laboratory and radiologic findings, microbiological results, and treatments were examined. Results Six patients had underlying structural-related problems (e.g., skeletal anomalies). No immunologic or hematologic problem was recorded. The mean ages of the primary and secondary groups were 2.4 and 5.3 years, respectively, but the difference was not statistically significant. The mean length of hospital stay was similar in both groups (22.8 days vs. 21.4 days). Immunologic studies were performed in 3 patients; the results were within the normal range. Most patients had prominent leukocytosis. Seven and 4 patients had right and left lung abscess, respectively. Staphylococcus aureus, Streptococcus pneumoniae, and antimycoplasma antibodies were detected in both groups. Two patients with primary lung abscess were administered antibiotics in the absence of other procedures, while 8 underwent interventional procedures, including 5 with secondary abscess. Conclusion The most common symptoms were fever and cough. All patients in the primary group were younger than 3 years. Structural problems were dominant. Most patients required interventional procedures and antibiotics. PMID:26770223

Staphylococcus aureus infection dynamics.

Pollitt, Eric J G; Szkuta, Piotr T; Burns, Nicola; Foster, Simon J

2018-06-01

Staphylococcus aureus is a human commensal that can also cause systemic infections. This transition requires evasion of the immune response and the ability to exploit different niches within the host. However, the disease mechanisms and the dominant immune mediators against infection are poorly understood. Previously it has been shown that the infecting S. aureus population goes through a population bottleneck, from which very few bacteria escape to establish the abscesses that are characteristic of many infections. Here we examine the host factors underlying the population bottleneck and subsequent clonal expansion in S. aureus infection models, to identify underpinning principles of infection. The bottleneck is a common feature between models and is independent of S. aureus strain. Interestingly, the high doses of S. aureus required for the widely used "survival" model results in a reduced population bottleneck, suggesting that host defences have been simply overloaded. This brings into question the applicability of the survival model. Depletion of immune mediators revealed key breakpoints and the dynamics of systemic infection. Loss of macrophages, including the liver Kupffer cells, led to increased sensitivity to infection as expected but also loss of the population bottleneck and the spread to other organs still occurred. Conversely, neutrophil depletion led to greater susceptibility to disease but with a concomitant maintenance of the bottleneck and lack of systemic spread. We also used a novel microscopy approach to examine abscess architecture and distribution within organs. From these observations we developed a conceptual model for S. aureus disease from initial infection to mature abscess. This work highlights the need to understand the complexities of the infectious process to be able to assign functions for host and bacterial components, and why S. aureus disease requires a seemingly high infectious dose and how interventions such as a vaccine may be more rationally developed.

Lung parenchymal abscesses represent an uncommon pathology with high mortality if untreated. Although most respond well to antibiotics, the optimal therapy for persistent abscesses is unknown. The purpose of this study was to review the outcomes of percutaneous lung parenchymal abscess catheter drainage after broad-spectrum antibiotic therapy failure and correlate with patient microbiologic samples. Retrospective review of patients who underwent percutaneous lung abscess drainage at a tertiary hospital system from 2005 to 2015 was performed. In total, 19 procedures were identified on 16 different patients; six females and ten males. Mean patient age was 55 years (range 22-81). Median follow-up time was 7 months (range <1-78). Technical success was 100%. There was one major complication, a pneumothorax. Follow-up was until tube removal or death in 100% of patients. Catheters were removed with resolution of the abscess cavity in 58% (11/19) or with non-draining abscess cavities in 21% (4/19) for a clinical success rate of 79%. Blood cultures demonstrated no growth in all cases, while 21% (4/19) of sputum or bronchoscopic cultures demonstrated growth. In comparison, the specimens from initial catheter placement isolated a causative organism in 95% (18/19) of case (p < 0.0001). In cases of persistent lung abscess after broad-spectrum antibiotics, percutaneous abscess drainage is highly sensitive for microbiologic sampling compared to sputum/bronchoscopic or blood cultures. Additionally, percutaneous drainage of lung parenchymal abscess cavities may promote resolution of the abscess with high rates of therapeutic success and low complications.

To investigate the diagnostic value of contrast-enhanced computed tomography (CT) for the prediction of deep neck abscesses in different deep neck spaces and to evaluate the false-positive results. We retrospectively analysed the clinical charts, CT examinations, surgical findings, bacteriology, pathological examinations and complications of hospitalised patients with a diagnosis of deep neck abscess from 2004 to 2010. The positive predictive values (PPV) for the prediction of abscesses by CT scan in different deep neck spaces were calculated individually on the basis of surgical findings. A total of 162 patients were included in this study. All patients received both intravenous antibiotics and surgical drainage. The parapharyngeal space was the most commonly involved space. The overall PPV for the prediction of deep neck abscess with contrast-enhanced CT was 79.6%. The PPV was 91.3% when more than one deep neck space was involved but only 50.0% in patients with isolated retropharyngeal abscesses. In the false-positive group, cellulitis was the most common final result, followed by cystic degeneration of cervical metastases. Five specimens taken intra-operatively revealed malignancy and four of these were not infected. There are some limitations affecting the differentiation of abscesses and cellulitis, particularly in the retropharyngeal space. A central necrotic cervical metastatic lymph node may sometimes also mimic a simple pyogenic deep neck abscess on both clinical pictures and CT images. Routine biopsy of the tissue must be performed during surgical drainage.

We report here a human case probably mixed-infected with Clonorchis sinensis and Fasciola sp. who was diagnosed by computed tomography (CT) scan, serological findings, and/or fecal examination. The patient was a 43-year-old Korean female and was admitted to Kyung Hee University Hospital with the complaints of fever and abdominal pain. On admission, marked eosinophilia was noted in her peripheral blood. CT scan showed specific lesions for clonorchiasis and fascioliasis in the liver, along with lesions suggestive of amebic abscess. Micro-ELISA revealed positive results for the 2 helminthic infections. Eggs of C. sinensis and trophozoites of Entamoeba histolytica were observed in the stool. Treatment with praziquantel followed by metronidazole and tinidazole reduced abnormalities in the liver and eosinophilia. This is the first case report of a possible co-infection with 2 kinds of liver flukes in the Republic of Korea.

Parasitic diseases in the abdomen: imaging findings.

Parasitic diseases of the liver and biliary tract include echinococcosis, schistosomiasis, toxocariasis, clonorchiasis, and opisthorchiasis, affecting millions people in some endemic areas. Amebiasis and ascariasis are believed to be the most common bowel lumen indwelling parasitic diseases, affecting billions people worldwide, but sometimes these parasites migrate inadvertently to the liver and biliary tract, resulting in liver abscess or obstructive jaundice. Imaging findings of these parasitic diseases are fairly characteristic and easy to recognize if radiologists are aware of the findings, especially in endemic areas. Because of increased immigration and frequent travelling, some patients with "exotic" parasitic diseases may be encountered in non-endemic areas, and the diagnosis may be delayed or difficult, and it is often made only after operation. This feature section was designed to provide the detailed imaging features of common parasitic diseases affecting the abdominal organs and peritoneal cavity, based on pathology-image correlation.

Spinal epidural abscesses in children: a 15-year experience and review of the literature.

PubMed

Auletta, J J; John, C C

2001-01-01

We reviewed medical records and laboratory and diagnostic evaluations for 8 pediatric patients with spinal epidural abscesses who were treated during the last 15 years at our institution. Staphylococcus aureus was isolated from 5 of 8 epidural abscesses, including 2 abscesses with methicillin-resistant S. aureus. Unusual isolates were group B Streptococcus in a patient with chronic vesicouretral reflux associated with the posterior urethral valves and Aspergillus flavus in a patient with acute myelogenous leukemia. An analysis incorporating our results and a review of the English-language literature about abscesses in children and adults revealed differences related to age. Abscesses in children were more posterior in epidural location, had greater spinal column extension, and were associated with more favorable clinical outcomes than were abscesses in adults. Magnetic resonance imaging is the diagnostic procedure of choice; however, radionuclide bone scans should be considered for associated distant osteomyelitis in children. Prompt diagnosis and combined medical and surgical treatment remain the cornerstones for the prevention of adverse outcomes.

Retropharyngeal abscess-like lesions are occasionally seen in computed tomography (CT) imaging of patients with Kawasaki disease (KD) and these patients often undergo unnecessary surgery. We could distinguish the lesions from true abscesses by measuring their Hounsfield unit values (HUs). To distinguish the retropharyngeal abscess-like lesions from true abscesses without any surgical procedure. We investigated six cases of KD showing such lesions on CTs, both with and without contrast enhancement (CE). We measured the HUs of those lesions and compared them with those of 10 true abscesses as controls. Abscess-like lesions of KD were well enhanced by CE, whereas abscesses showed virtually no enhancement. The mean HU in the six KD cases was 20.0 ± 4.65 (mean ± SD) on plain CTs and 35.6 ± 4.49 on contrast CTs. In abscesses, it was 30.3 ± 4.42 on plain CTs and 30.3 ± 3.57 on contrast CTs. The difference in HU values [(HU on contrast CT) - (HU on plain CT)] was defined as ΔHU. The mean ΔHU was 15.6 ± 5.36 in the six KD lesions and 0.0 ± 2.93 in abscesses, with statistical significance of p < 0.0001 by Student's t test. Thus, ΔHU value may potentially be a useful parameter for their distinction.

A 73-year-old woman who had been followed in our department of gynecology because of ovarian cancer since 2002, was admitted with liver dysfunction and complaining of back pain and light precordial chest pain. The chest radiograph on admission revealed a tumor in her left upper lung field, and chest CT revealed a tumor adjacent to the chest wall and mediastinum. FDG-positron emission tomography (PET) showed abnormal uptake in the tumor and Th6/7, and the subaortic lymph nodes. On the basis of these findings, primary lung cancer with bone metastasis was suspected. She had a high grade fever on admission, and blood cultures were positive for group G streptococcus. The treatment with intravenous penicillin was started. Percutaneous biopsy of the tumor in her left chest showed an abscess wall in the chest wall, but no evidence of malignancy. Transbronchial lung biopsy and CT-guided biopsy also showed no malignant cells. Since the tumor decreased in size and back pain improved gradually by only antibiotic treatment, a diagnosis of sepsis of group G streptococcus, chest wall abscess, and vertebral osteomyelitis was made. She was treated with intravenous penicillin for 4 weeks and oral amoxicillin for another 4 weeks. After 60 days of antibiotic treatment, the tumor vanished.

Many patients with breast abscess are managed in primary care. Knowledge of current trends in the bacteriology is valuable in informing antibiotic choices. This study reviews bacterial cultures of a large series of breast abscesses to determine whether there has been a change in the causative organisms during the era of increasing methicillin-resistant Staphylococcus aureus (MRSA). Analysis was undertaken of all breast abscesses treated in a single unit over 2003 - 2006, including abscess type, bacterial culture, antibiotic sensitivity and resistance patterns. One hundred and ninety cultures were obtained (32.8% lactational abscess, 67.2% nonlactational). 83% yielded organisms. Staphylococcus aureus was the commonest organism isolated (51.3%). Of these, 8.6% were MRSA. Other common organisms included mixed anaerobes (13.7%), and anaerobic cocci (6.3%). Lactational abscesses were significantly more likely to be caused by S. aureus (p < 0.05). Methicillin-resistant Staphylococcus aureus rates were not statistically different between lactational and nonlactational abscess groups. Appropriate antibiotic choices are of great importance in the community management of breast abscess. Ideally, microbial cultures should be obtained to institute targeted therapy but we recommend the continued use of flucloxacillin with or without metronidazole (or amoxicillin-clavulanate as a single preparation) as initial empirical therapy.

Understanding the Lung Abscess Microbiome: Outcomes of Percutaneous Lung Parenchymal Abscess Drainage with Microbiologic Correlation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Duncan, Christopher; Nadolski, Gregory J.; Gade, Terence

IntroductionLung parenchymal abscesses represent an uncommon pathology with high mortality if untreated. Although most respond well to antibiotics, the optimal therapy for persistent abscesses is unknown. The purpose of this study was to review the outcomes of percutaneous lung parenchymal abscess catheter drainage after broad-spectrum antibiotic therapy failure and correlate with patient microbiologic samples.Materials and MethodsRetrospective review of patients who underwent percutaneous lung abscess drainage at a tertiary hospital system from 2005 to 2015 was performed. In total, 19 procedures were identified on 16 different patients; six females and ten males. Mean patient age was 55 years (range 22–81). Median follow-upmore » time was 7 months (range <1–78).ResultsTechnical success was 100%. There was one major complication, a pneumothorax. Follow-up was until tube removal or death in 100% of patients. Catheters were removed with resolution of the abscess cavity in 58% (11/19) or with non-draining abscess cavities in 21% (4/19) for a clinical success rate of 79%. Blood cultures demonstrated no growth in all cases, while 21% (4/19) of sputum or bronchoscopic cultures demonstrated growth. In comparison, the specimens from initial catheter placement isolated a causative organism in 95% (18/19) of case (p < 0.0001).ConclusionIn cases of persistent lung abscess after broad-spectrum antibiotics, percutaneous abscess drainage is highly sensitive for microbiologic sampling compared to sputum/bronchoscopic or blood cultures. Additionally, percutaneous drainage of lung parenchymal abscess cavities may promote resolution of the abscess with high rates of therapeutic success and low complications.« less

A coagulase-negative and non-haemolytic strain of Staphylococcus aureus for investigating the roles of SrtA in a murine model of bloodstream infection.

Sortase A (SrtA) is a cysteine transpeptidase and virulence factor from Staphylococcus aureus (S. aureus) that catalyses the attachment and display of surface proteins on the cell wall, thereby mediating bacterial adhesion to host tissues, host-cell entry and evasion of the immune response. As a result, SrtA has become an important target in the development of therapies for S. aureus infections. In this study, we used the new reference strain S. aureus Newman D2C to investigate the role of SrtA in a murine model of bloodstream infection, when the impact of coagulase and haemolysin is excluded. The results suggested that deletion of SrtA reduced the bacterial burden on the heart, liver and kidneys by blunting the host proinflammatory cytokine response at an early point in infection. Kidneys, but not heart or liver, formed abscesses on the sixth day following non-lethal infection, and this effect was diminished by SrtA mutation. These findings indicate that SrtA is a determining virulence factor in lethality and formation of renal abscesses in mice followed by S. aureus bloodstream infection. We have thus established a convenient in vitro and mouse model for developing SrtA-targeted therapeutic strategies. © FEMS 2015. All rights reserved.

Enterobius vermicularis in tubo-ovarian abscess: A rare and interesting incidental finding - A case Report.

PubMed

Saleem, Faryal; Malik, Faizan; Fatima, Saira

2017-04-01

Enterobius vermicularis is a common intestinal nematode; however, rare extraintestinal Enterobius infections have been reported from different parts of the world. Here, we present a case of tubo-ovarian abscess in an otherwise healthy young sexually active female with no known comorbids with history of on and off lower abdominal pain for one year and high grade fever for one month. On the basis of further workup and radiological evaluation, a preoperative diagnosis of right sided tubo-ovarian abscess was made and salpingo-oophorectomy was performed laproscopically in July 2015. Histopathology of the resected tissue revealed necrosis and in one area Enterobius vermicularis was identified surrounded by neutrophils and eosinophil rich abscess. A final diagnosis of severe acute and chronic salpingo-oophoritis with abscess formation, secondary to Enterobius vermicularis was made. Signs and symptoms of parasitic involvement in tubo-ovarian abscesses are not much different than usual presentations of pelvic inflammatory diseases and identification of a parasite in a tubo-ovarian tissue sample is a rare clinical finding. A high index of suspicion on the part of histopathologist as well as clinician is important for timely diagnosis and effective management of such cases.

This study investigated the presence and levels of matrix metalloproteinases (MMP)-2 and -9 in periapical abscesses. Eighteen samples of intracanal exudates containing pus were collected from teeth with clinically and radiographically verified primary or secondary acute and chronic apical abscesses. Pro- and active forms of MMP-2 and MMP-9 levels were analyzed by using substrate gel zymography followed by an image analysis system. Statistical analysis was performed using the Kruskall-Wallis and Mann-Whitney U tests with Bonferroni adjustment. Both forms of MMP-9 were detected in all pus samples and demonstrated marked differences among the experimental groups (P < .05). Primary or secondary acute apical abscess samples demonstrated significantly higher MMP-9 levels compared with MMP-2 levels (P < .01). However, MMP-2 could not be detected in chronic apical abscesses. According to the results of this study, gelatinases might affect the pathogenesis of acute and chronic periapical abscesses.

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

2004-12-01

There have been a number of reports of brain abscesses suggesting an odontogenic etiology. However, no efforts have been made to compare brain abscess isolates with isolates from the oral cavity using highly discriminative methods. We report a brain abscess caused by Streptococcus constellatus in an immunocompromised patient where oral infection (periodontitis) was suspected to be implicated. The brain abscess and oral isolates were compared by means of one phenotypic and three genetic (restriction fragment length polymorphism [RFLP], ribotyping, and random amplified polymorphic DNA [RAPD]) fingerprinting techniques. The phenotypic method and RFLP showed identical profiles between brain and periodontal isolates, while ribotyping and RAPD showed very close similarity, with only one band difference in one of the three ribotypes and in one of the three polymorphic RAPD. Gene transfer by genetic recombinational events in the periodontal pocket might have been responsible for the emergence of a strain variant of S. constellatus that had the potential to cause an abscess at a distant site (brain). The importance of odontogenic sources as potential foci of infection for brain abscesses is discussed.

Brain abscess is one of the most serious diseases of the central nervous system. This condition is more common among men--twice to three times, and morbidity rate is highest in fourth decade of the life. Etiologic agents of brain abscess are bacteria, fungus, protozoa and parasites. The development of the brain abscess can resulted from the spread of infection from local sites or bloodborne from distal sites. In 10-15% of cases multiple abscesses develop. Headache is the most common syndrome. The radiologic tests: computed tomography or magnetic resonance are tests of choice in diagnosis and monitoring of treatment. Treatment of brains abscesses required cooperation of different specialists: infectious diseases, neuroradiologist, neurologists and neurosurgeon. Decision about therapeutic methods depends on number, size and localization of lesions, and patient's condition. In conservative treatment empiric antibiotic therapy and supportive treatment are used. Actually two methods of surgical treatment are used: CT- guided stereotactic aspiration and incision of the brain abscess by craniotomy. Actually mortality rate is 6 to 24%. Among 30-56% patients permanent neurological complications are reported.

Chromobacterium Violaceum Sepsis: Rethinking Conventional Therapy to Improve Outcome

Patient: Male, 11 Final Diagnosis: Chromobacterium violaceum infection Symptoms: Abscess • fever • rash Medication: — Clinical Procedure: ECMO Specialty: Critical Care Medicine Objective: Rare disease Background: Chromobacterium violaceum (C. violaceum) is a facultative anaerobic gram-negative bacterium found in soil and water, especially in tropical and subtropical areas. Although infection in humans is rare, it is associated with significant morbidity. The bacterium is known for its resistance to multiple antimicrobials, and the possibility of relapse and reinfection. Presence of bacteremia, disseminated infection, and ineffective antimicrobial agents are predictors of mortality. Case Report: We report the case of a previously healthy 11-year-old male with C. violaceum sepsis who was exposed to stagnant water. He presented with severe septic shock and developed multi-organ system failure. Initial presumptive diagnosis was staphylococcal infection secondary to presence of skin abscesses resulting in antibiotic coverage with vancomycin, clindamycin, nafcillin and ceftriaxone. He also had multiple lung and liver abscesses. Once C. violaceum was identified, he received meropenem and ciprofloxacin, and was later discharged on ertapenem and trimethoprim-sulfamethoxazole (TMP-SMX) to complete a total of six months of antibiotics. He was diagnosed with chronic granulomatous disease (CGD) and is currently on prophylactic TMP-SMX and itraconazole. He has not had any relapses since his initial presentation. Conclusions: This case highlights the importance of considering C. violaceum as a relevant human pathogen, and considering it early in temperate regions, particularly in cases of fulminant sepsis associated with multi-organ abscesses. Once C. violaceum is identified, appropriate antimicrobial therapy should be started promptly, and sufficient duration of treatment is necessary for successful therapy. PMID:26477750

Infection with the introduced trematode Fasciola hepatica was associated with anemia, mild to moderate azotemia, hypoalbuminemia, and elevated liver enzymes and creatine kinase values in two free-ranging eastern grey kangaroos (Macropus giganteus). Both kangaroos were euthanized because of the severity of clinical signs associated with infection. Histopathologic changes included severe cholangiohepatitis, biliary hyperplasia, and fibrosis. Hepatic, splenic, and intestinal amyloidosis was present in one kangaroo and hepatic abscessation in the other; neither histologic change has been reported in macropodids with fascioliasis previously.

To investigate objective measures that could increase the positive predictive value of computed tomography (CT) in diagnosing deep neck space infections (DNSIs). A retrospective analysis of patients surgically treated at a tertiary care hospital for DNSIs for more than 2 years were reviewed. Patients who had had CT with contrast scanning suggestive of deep neck space abscess within 24 hours before surgery were included. The average Hounsfield units for each abscess were calculated. Based on the intraoperative finding of pus, the patients were divided into groups. Student t tests compared the average Hounsfield units, white blood cell count, and maximum temperature between the groups. Outcomes were measured by comparing overall length of hospital stay, length of postoperative stay, and complications. Of the 32 patients surgically drained, 24 (75%) had discreet collections of pus, whereas 12 (25%) did not. Hounsfield unit measurement was not reliable in distinguishing abscess from phlegmon. None of the other clinical variables studied to distinguish abscess from phlegmon were statistically different either. A statistical difference between the 2 groups was not identified. Although CT with contrast plays an important role in the diagnosis and management of DNSIs, the decision for surgical drainage of an abscess should be made clinically. A negative exploration rate of nearly 25% despite careful selection criteria should be expected.

Breast abscess is commonly seen in lactating and non-lactating women. Diabetes mellitus (DM) frequently predisposes to soft tissue infections and has many different presentations. But DM presenting in the form of breast abscess is yet to be studied, and we believe our study is the first to explore this connection. We collected 30 cases of breast abscess in women who presented to our hospital from May 2010 to June 2011 retrospectively. They were classified into lactating and non-lactating women, and their glycemic status was evaluated, together with length of hospital stay, management, recurrence, and follow-up status after 6 months. We found that of the 30 patients in our study, 20% had high blood sugar levels. And 37.5% of the non-lactating women were diagnosed newly with DM. This study shows that DM can present as breast abscess in non-lactating women. Therefore, non-lactating women with a breast abscess should be evaluated for DM.

Chronic granulomatous disease (CGD) is a genetically heterogeneous primary immunodeficiency that is characterized by recurrent and life-threatening infections resulting from defects in phagocyte nicotinamide adenine dinucleotide phosphate (NADPH) oxidase system and granuloma formation due to increased inflammatory response. The most commonly involved organs are the lungs, skin, lymph nodes, and liver due to infection. It may present with recurrent pneumonia, hilar lymphadenopathy, empyema, abscess, reticulonodular patterns, and granulomas due to lung involvement. In recent years, mycobacterial disease susceptibility has been reported in CGD cases. This article presents two male cases, one of whom is aged 18 months and the other is aged 5 years, who were diagnosed with CGD and tuberculosis during examination due to extended pneumonia. This report is presented because CGD should be considered not only in the presence of skin abscesses and Aspergillus infections, but also in the differential diagnosis for cases with BCG-itis and/or tuberculosis. It should be kept in mind that mycobacterial infections can occur during the course of the disease.

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.

Hyperammonemia, abnormalities in plasma amino acids and abnormalities of standard liver functions were corrected by orthotopic liver transplantation in a 14-day-old boy with carbamyl phosphate synthetase-I deficiency and in a 35-yr-old man with argininosuccinic acid synthetase deficiency. The first patient had high plasma glutamine levels and no measureable citrulline, whereas citrulline values were markedly increased in Patient 2. Enzyme analysis of the original livers showed undetectable activity of carbamyl phosphate synthetase-I in Patient 1 and arginosuccinic acid synthetase in Patient 2. Both patients were comatose before surgery. Intellectual recovery of patient 1 has been slightly retarded because of a brain abscess caused by Aspergillus infection after surgery. Both patients are well at 34 and 40 mo, respectively, after surgery. Our experience has shown that orthotopic liver transplantation corrects the life-threatening metabolic abnormalities caused by deficiencies in the urea cycle enzymes carbamyl phosphate synthetase-I and arginosuccinic acid synthetase. Seven other patients–six with ornithine transcarbamylase deficiency and another with carbamyl phosphate synthetase-I deficiency–are known to have been treated elsewhere with liver transplantation 1½ yr or longer ago. Four of these seven recipients also are well, with follow-ups of 1½ to 5 yr. Thus liver transplantation corrects the metabolic abnormalities of three of the six urea cycle enzyme deficiencies, and presumably would correct all. PMID:1544622

Abscesses are a classic host response to infection by many pathogenic bacteria. The immunopathogenesis of this tissue response to infection has not been fully elucidated. Previous studies have suggested that T cells are involved in the pathologic process, but the role of these cells remains unclear. To delineate the mechanism by which T cells mediate abscess formation associated with intra-abdominal sepsis, the role of T-cell activation and the contribution of antigen-presenting cells via CD28-B7 costimulation were investigated. T cells activated in vitro by zwitterionic bacterial polysaccharides (Zps) known to induce abscess formation required CD28-B7 costimulation and, when adoptively transferred to the peritoneal cavity of naïve rats, promoted abscess formation. Blockade of T-cell activation via the CD28-B7 pathway in animals with CTLA4Ig prevented abscess formation following challenge with different bacterial pathogens, including Staphylococcus aureus, Bacteroides fragilis, and a combination of Enterococcus faecium and Bacteroides distasonis. In contrast, these animals had an increased abscess rate following in vivo T-cell activation via CD28 signaling. Abscess formation in vivo and T-cell activation in vitro required costimulation by B7-2 but not B7-1. These results demonstrate that abscess formation by pathogenic bacteria is under the control of a common effector mechanism that requires T-cell activation via the CD28–B7-2 pathway. PMID:11083777

The major risk factor for Klebsiella liver abscess (KLA) is type 2 diabetes mellitus (DM), but the immunological mechanisms involved in the increased susceptibility are poorly defined. We investigated the responses of neutrophils and peripheral blood mononuclear cells (PBMCs) to hypervirulent Klebsiella pneumoniae (hvKP), the causative agent of KLA. DNA and myeloperoxidase levels were elevated in the plasma of KLA patients compared to uninfected individuals indicating neutrophil activation, but diabetic status had no effect on these neutrophil extracellular trap (NET) biomarkers in both subject groups. Clinical hvKP isolates universally stimulated KLA patient neutrophils to produce NETs ex vivo, regardless of host diabetic status. Ability of representative capsule types (K1, K2, and non-K1/K2 strains) to survive intra- and extra-cellular killing by type 2 DM and healthy neutrophils was subsequently examined. Key findings were: (1) type 2 DM and healthy neutrophils exhibited comparable total, phagocytic, and NETs killing against hvKP, (2) phagocytic and NETs killing were equally effective against hvKP, and (3) hypermucoviscous K1 and K2 strains were more resistant to total, phagocytic, and NETs killing compared to the non-mucoviscous, non-K1/K2 strain. The cytokine response and intracellular killing ability of type 2 DM as well as healthy PBMCs upon encounter with the different capsule types was also examined. Notably, the IL-12–IFNγ axis and its downstream chemokines MIG, IP-10, and RANTES were produced at slightly lower levels by type 2 DM PBMCs than healthy PBMCs in response to representative K1 and non-K1/K2 strains. Furthermore, type 2 DM PBMCs have a mild defect in its ability to control hvKP replication relative to healthy PBMCs. In summary, our work demonstrates that type 2 DM does not overtly impact neutrophil intra- and extra-cellular killing of hvKP, but may influence cytokine/chemokine production and intracellular killing by PBMCs.

We present the case of a middle-aged woman with antecedents of cholecystectomy and several episodes of resi-dual coledocolitiasis resolved endoscopically. She attended Emergency Services due to a new clinical picture of abdo-minal pain and alteration of hepatic enzymes. Image tests showed lesions that suggested hepatic abscesses without ruling out a malign origin. Given this doubt it was decided to carry out a thick needle biopsy obtaining a diagnosis of an inflammatory pseudotumour of the liver related to IgG4-related disease. This is an infrequent entity but must be taken into consideration because - unlike malign pathology, which is the main differential diagnosis - its behaviour is benign, with a good evolution with medical treatment. That is why a suitable diagnosis is vital to avoid aggressive, diagnostic-therapeutic procedures.

The article deals with the author's views on certain aspects of the problem of reconstructive and restorative surgery of the biliary tract. Original methods are suggested for external drainage (through the inferior surface of the right hepatic lobe in the region of the gallbladder seat and through the round ligament of the liver) in formation of ++hepato-hepatico- and hepaticojejunoanastomoses. Problems of operative techniques in formation of the anastomoses are discussed. Thirty-nine operations have been carried out in the clinic in the recent decade in high strictures and traumas of the biliary tract, 25 were reconstructive and 14 restorative. Postoperative mortality was 28.2% (11 patients). Intoxication and hepatargia associated with cholangiolytic abscesses of the liver were the main causes of death.

An 11-year-old Holstein-Friesian cow exhibited anorexia and jaundice. A large mass was found in the liver during necropsy. Macroscopically, the mass was composed of dark red multilobular tissue and a centrally located abscess, which was connected to the hepatic duct. Histologically, the mass consisted of proliferation of small neoplastic cells and was demarcated from the hepatic parenchyma by a thick region of granulation tissue. The neoplastic cells were predominantly arranged in solid sheets, but they also formed blood-filled cancellous structures, and proliferating foci were seen around blood vessels. Periodic acid-Schiff reaction demonstrated that a fine basement membrane-like structure surrounded the neoplastic cells. Immunohistochemically, the neoplastic cells were positive for vimentin and alpha smooth muscle actin and negative for cytokeratin, factor VIII-related antigen, chromogranin and desmin. Based on its histopathological features, the hepatic neoplasm was diagnosed as a primary glomus tumor. This is the first report about a primary glomus tumor of the liver in a cow. PMID:25715802

Cutaneous abscesses have traditionally been treated with incision and drainage (I&D) and left to heal by secondary closure. The objective was to compare the healing rates of cutaneous abscesses following I&D after primary or secondary closure. This was a randomized, controlled, trial, balanced by center, with blocked randomization created by a random-number generator. One urban and one suburban academic emergency department (ED) participated. Subjects were randomized to primary or secondary wound closure following I&D of the abscess. Main outcome measures were the percentage of healed wounds (wound was completely closed by visual inspection; a 40% difference in wound healing was sought) and overall failure rate (need for additional intervention including suture removal, additional drainage, antibiotics, or admission within 7 days after drainage). Fifty-six adult patients with simple localized cutaneous abscesses were included; 29 were randomized to primary closure, and 27 were randomized to secondary closure. Healing rates at 7 days were similar between the primary and secondary closure groups (69.6%, 95% confidence interval [CI] = 49.1% to 84.4% vs. 59.3%, 95% CI = 40.7% to 75.5%; difference 10.3%, 95% CI = -15.8% to 34.1%). Overall failure rates at 7 days were also similar between the primary and secondary closure groups (30.4%, 95% CI = 15.6% to 50.9% vs. 28.6%, 95% CI = 15.2% to 47.1%; difference 1.8%, 95% CI = -24.2% to 28.8%). The rates of wound healing and treatment failure following I&D of simple abscesses in the ED are similar after primary or secondary closure. The authors did not detect a difference of at least 40% in healing rates between primary and secondary closure. © 2013 by the Society for Academic Emergency Medicine.

Holospinal epidural abscesses - Institutional experience.

Bridges, Kelly J; Than, Khoi D

2018-02-01

The authors present a holospinal epidural abscesses (HEA) case series and a single institution's experience with varied surgical approaches and outcomes. Medical records were queried and reviewed (6 years) for patients with a spinal abscess diagnosis; HEA were selected. Medical history, comorbidities, blood and epidural pathogens, presentation symptoms, abscess location, presence of mass effect, surgical procedures, treatment regimens, and neurological outcomes were collected. Eight patients with HEA were treated; all underwent surgery. In the index procedure, one (12.5%) underwent laminectomy of the entire spinal column, four (50%) focal laminectomies at the area of mass effect, and three (37.5%) skip laminectomies. Of the four patients who initially had focal laminectomies, three (75%) required additional operations for abscess evacuation in other spine regions. Average number of laminectomies per patient was 8.6. Neurologically, 50% of patients improved, 37.5% remained stable, and 12.5% worsened. There was no difference in outcome between patients who underwent skip versus panspinal laminectomies. No differences in outcomes were noted in timing from presentation to surgery (median 5.3 h), location of mass effect, dorsal versus ventral abscesses, or initial symptoms. Of the four patients who had cervical laminectomy without fusion, two developed post-laminectomy kyphosis requiring fusion. Cervical instability occurred in half the patients who underwent cervical laminectomies without fusion, and there were no adverse outcomes in the patients who were fused in the setting of infection. For lower cervical abscess, upper thoracic laminectomy with catheter irrigation may be sufficient for decompression, minimizing risk of future instability. Copyright © 2017 Elsevier Ltd.

Taiwan is endemic for pyogenic liver abscess (PLA). Septic ocular or central nervous system (CNS) complications derived from PLA can result in catastrophic disability. We investigated the epidemiology and long-term prognosis of PLA patients with septic ocular or CNS complications over an 8-year period. We extracted 21,307 patients with newly diagnosed PLA from a nationwide health registry in Taiwan between 2000 and 2007. The frequency of and risk factors for PLA with septic ocular or CNS complications were determined. The 2-year survival of these patients was compared between those with and without septic ocular or CNS complications. Septic ocular or CNS complications accounted for 2.1% of all PLA patients. Age and the Charlson comorbidity index were significantly lower in PLA patients with ocular or CNS complications than those without. Diabetes and age <65 years were independent predictors of septic ocular or CNS complications. The 2-year mortality of patients with septic ocular or CNS complications was similar to those without complications (24.8% vs. 27.5%, p = 0.502). However, among patients <65 years old and a Charlson index ≤ 1, the 2-year mortality was significantly higher in those with than without complications (18.6% vs. 11.8%, p = 0.001). Physicians should recognize that catastrophic disability due to ocular or neurological complications from PLA could lead to a poor long-term prognosis, and should follow-up these patients more closely.

The purpose of this study was to investigate the relationship between periodontitis, dental scaling (DS) and pyogenic liver abscesses (PLAs). A nationwide population-based case-control study was applied using data from the National Health Insurance Research Database in Taiwan. We identified and enrolled 691 PLA patients, who were individually matched by age and sex to 2764 controls. Conditional logistic regression was applied to estimate adjusted odds ratios (aORs) in patients with exposure to periodontitis and DS before PLA. After adjusting for other confounding factors, periodontitis remained a risk factor for PLA among patients aged 20-40 years, with an aOR of 2.31 (95% confidence interval [CI] = 1.37-3.90, P = .0018). In addition, the average aOR for PLA was significantly lower among patients with one DS (aOR = 0.76, 95% CI = 0.59-0.96) and more than one DS (aOR = 0.61, 95% CI = 0.39-0.95) within 1 year before the index date. According to these results, we concluded that adult patients with periodontitis aged <50 years old are more at risk for PLA than controls, particularly when they have no DS. Moreover, from 20 years of age, non-periodontal patients subjected to at least 2 DS per year are less at risk for PLA than controls. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Eyelid edema in children is one of the signs of orbital complications secondary to acute rhinosinusitis, and identifying abscess formation is crucial for management decision. The objective of this study is to determine whether there are different computed tomography scan abscess dimensions and volumes in children requiring medical versus surgical management for subperiosteal orbital abscess (SPOA). Case series with chart review. The study was conducted at Assaf Harofeh Medical Center. Clinical and radiological parameters of 95 children admitted with eyelid edema between January 2005 and December 2007 were studied. Of 95 cases of orbital cellulitis, a total of 48 children with sinogenic orbital complications with a mean (SD) age of 4.03 (3.46) years were included. No significant difference was found between the surgically and medically treated SPOA groups regarding the use of preadmission antibiotic and clinical presentation. Statistically significant larger abscesses in the surgically treated group were noted (mean volume 1.389 vs 0.486 mL in the conservatively treated group; P = .013) and a longer mean anterior-posterior and medial-lateral dimension (P = .001 and .017, respectively). Children presenting with significant or progressing ocular findings or failure to improve after 48 hours of medical therapy, together with an abscess volume of more than 0.5 mL, a length greater than 17 mm, and a width greater than 4.5 mm, should be strongly considered to have surgical drainage.

Gastroenterological emergencies in the tropics.

PubMed

Cook, G C

1991-12-01

Significant differences exist in the prevalence of most gastroenterological emergencies in tropical compared with temperate countries. Both ethnic and environmental (often clearly defined geographically) factors are relevant. The major oesophageal lesions which can present acutely in tropical countries are varices and carcinoma; bleeding and obstruction are important sequelae. Peptic ulcer disease (and its complications), often associated (not necessarily causally) with Helicobacter pylori infection, has marked geographical variations in incidence. Emergencies involving the small intestine are dominated by severe dehydration, and its sequelae, resulting from secretory diarrhoea, most notably cholera. However, enteritis necroticans ('pig bel' disease), paralytic ileus (sometimes caused by antiperistaltic agents) and obstruction (secondary to luminal helminths, volvulus and intussusception) are other important problems, especially in infants and children. Enteric fever is occasionally complicated by perforation and haemorrhage; the former (which is notoriously difficult to manage) is accompanied by significant mortality. Ileocaecal tuberculosis is a major cause of right iliac fossa pathology--sometimes associated with malabsorption; amoeboma is an important clinical differential diagnosis. The colon can be involved in invasive Entamoeba histolytica infection (which, like complicated enteric fever, is difficult to manage if the fulminant form, with perforation, ensues), shigellosis, volvulus and intussusception. Acute colonic dilatation occasionally follows Salmonella sp., Shigella sp., Campylobacter jejuni, Yersinia enterocolitica and rarely E. histolytica infections. Acute hepatocellular failure is a major cause of morbidity and mortality in the tropics and subtropics. It usually results from viral hepatitis (HBV, sometimes complicated by HDV, and HCV), but there is a long list of differential diagnoses. Hepatotoxicity resulting from herbs, chemotherapeutic agents or alcohol also occurs not infrequently. Chronic liver disease and its sequelae (often long-term results of viral hepatitis) are commonplace. Haematemesis and hepatocellular failure are usually very difficult to manage due to a lack of sophisticated support techniques in developing countries. Invasive hepatic amoebiasis usually responds well to medical management; however, spontaneous perforation can occur and the consequences of this are serious. Pyogenic liver abscess, although far less common than amoebic 'abscess', carries a bad prognosis whatever the method(s) of management. Hydatidosis and schistosomiasis also involve the liver, and helminthiases are important in the context of biliary tract disease. Gall stones are unusual in most tropical settings. Acute pancreatitis is overall unusual, but chronic calcific pancreatitis can present as an acute abdominal emergency.

Forty-eight patients were scanned with /sup 111/In-chloride in an attempt to identify the cause of fever. Fifteen true positive scans, 30 true negatives, and 3 false negatives were found. Of the 15 true positives, 7 cases of abdominal or pelvic abscess, and 8 cases of alcoholic hepatitis were detected. The 3 false negatives included: (1) an abscess in the anterior abdominal wall; (2) an abscess in the right upper quadrant at the site of a necrotic gallbladder; and (3) a tuberculous abscess of the lumbar spine. Examples from the different categories, pitfalls in interpretation and advantages and disadvantages of scanningmore » with /sup 111/In-chloride will be presented.

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. 2015 BMJ Publishing Group Ltd.

Delayed colonic anastomosis after damage control laparotomy (DCL) is an alternative to colostomies during a single laparotomy (SL) in high-risk patients. However, literature suggests increased colonic leak rates up to 27% with DCL, and various reported risk factors. We evaluated our regional experience to determine if delayed colonic anastomosis was associated with worse outcomes. A multicenter retrospective cohort study was performed across three Level I trauma centers encompassing traumatic colon injuries from January 2006 through June 2014. Patients with rectal injuries or mortality within 24 hours were excluded. Patient and injury characteristics, complications, and interventions were compared between SL and DCL groups. Regional readmission data were utilized to capture complications within 6 months of index trauma. Of 267 patients, 69% had penetrating injuries, 21% underwent DCL, and the mortality rate was 4.9%. Overall, 176 received primary repair (26 in DCL), 90 had resection and anastomosis (28 in DCL), and 26 had a stoma created (10 end colostomies and 2 loop ileostomies in DCL). Thirty-five of 56 DCL patients had definitive colonic repair subsequent to their index operation. DCL patients were more likely to be hypotensive; require more resuscitation; and suffer acute kidney injury, pneumonia, adult respiratory distress syndrome, and death. Five enteric leaks (1.9%) and three enterocutaneous fistulas (ECF, 1.1%) were identified, proportionately distributed between DCL and SL (p = 1.00, p = 0.51). No difference was seen in intraperitoneal abscesses (p = 0.13) or surgical site infections (SSI, p = 0.70) between cohorts. Among SL patients, pancreas injuries portended an increased risk of intraperitoneal abscesses (p = 0.0002), as did liver injuries in DCL patients (p = 0.06). DCL was not associated with increased enteric leaks, ECF, SSI, or intraperitoneal abscesses despite nearly two-thirds having delayed repair. Despite this being a multicenter study, it is underpowered, and a prospective trial would better demonstrate risks of DCL in colon trauma. Therapeutic study, level IV.

This retrospective review assessed the safety and validity of elective liver resection in patients older than 64 years of age. In all, 293 patients underwent elective liver resection over a 23-year period (1967-1990). Fifty-two patients (18 per cent) were older than 64 (maximum 84, mean 70.4) years and all but four of these did not have cirrhosis. In this older subgroup, indications for resection were liver metastases in 30 patients, primary malignancy in 16, benign tumours in five and multiple abscesses in one. There were 21 major resections, with two deaths from hepatic failure, and 31 minor resections, with one death from cardiac failure (total mortality rate 6 per cent). During the same period, there were seven deaths after elective resections performed in 222 patients without cirrhosis who were younger than 64 years (P = 0.39). Mortality rate and duration of postoperative hospital stay were not related to the extent of liver resection nor to patients' grading according to the American Society of Anesthesiologists' criteria. Intraoperative blood loss was the only parameter found to influence mortality rate (P = 0.008) and duration of hospital stay (P = 0.04). Elective liver resection can be safely undertaken in elderly patients without cirrhosis, provided that intraoperative blood loss is minimized.

High extracellular concentration of excitatory amino acids glutamate and aspartate in human brain abscess.

2014-04-01

Brain abscesses often cause symptoms of brain dysfunction, including seizures, suggesting interference with normal neurotransmission. We determined the concentration of extracellular neuroactive amino acids in brain abscesses from 16 human patients. Glutamate was present at 3.6 mmol/L (median value, range 0.5-10.8), aspartate at 1.0 mmol/L (range 0.09-6.8). For comparison, in cerebroventricular fluid glutamate was ∼0.6 μmol/L, and aspartate was not different from zero. The total concentration of amino acids was higher in eight patients with seizures: 66 mmol/L (median value, range 19-109) vs. 21 mmol/L (range 4-52) in eight patients without seizures (p=0.026). The concentration of aspartate and essential amino acids tryptophan, phenylalanine, tyrosine, leucine, and isoleucine was higher in pus from patients with seizures (p⩽0.040), whereas that of glutamate was not (p=0.095). The median concentration of the non-proteinogenic, inhibitory amino acid taurine was similar in the two groups, 0.7-0.8 mmol/L (range 0.1-6.1). GABA could not be detected in pus. The patient groups did not differ with respect to abscess volume, the cerebral lobe affected, age, or time from symptom onset to surgery. Seven patients with extracerebral, intracranial abscesses had significantly lower pus concentration of glutamate (352 μmol/L, range 83-1368) and aspartate (71 μmol/L, range 22-330) than intracerebral abscesses (p<0.001). We conclude that excitatory amino acids glutamate and aspartate may reach very high concentrations in brain abscesses, probably contributing to symptoms through activation of glutamate receptors in the surrounding brain tissue.

INTRODUCTION: Pediatric lung abscesses can be primary or secondary, and there is limited data regarding response to treatments and patient outcomes. OBJECTIVES: To assess the clinical and microbiologic profile of pediatric patients with lung abscess and assess the differences in outcomes for patients treated with medical therapy or medical plus surgical therapy. METHODS: A retrospective review of all pediatric patients ≤ 18 years of age that were treated as an inpatient for lung abscess between the dates of August 2004 and August 2014 was conducted. Patients were divided into two subgroups based on the need for surgical intervention. RESULTS: A total of 39 patients with lung abscess (30 treated with medical therapy alone, 9 also required surgical interventions) were included. Fever, cough, and emesis were the most common presenting symptoms, and most of the patients had underlying respiratory (31%) or neurologic disorders (15%). Staphylococcus aureus was the most common organism in those that had culture results available, and ceftriaxone with clindamycin was the most common combination of antibiotics used for treatment. Comparison of medical and surgical subgroups identified the duration of fever and abscess size as risk factors for surgical intervention. CONCLUSIONS: Pediatric lung abscesses can be managed with medical therapy alone in most cases. Presence of prolonged duration of fever and larger abscess size may be predictive of the need for surgical intervention. Good clinical response to prolonged therapy with ceftriaxone and clindamycin was noted. PMID:27512508

There has only a small number of invasive amoebiasis cases occurred in Hungary up to now. Introducing two of our cases we would like to call attention on these cases coming mainly from tropical countries or having been just transiently there invasive amoebiasis should also be considered. Modern diagnostic imaging technics are of importance in differential diagnosis in showing antibodies against amoebas (!) because amoebas frequently cannot be directly shown from the patients in the invasive stage. Both ulcerous amoebic colitis and amoebic liver abscesses can be treated with drugs affecting amoebas in deep tissues (metronidazole, emetine, and its derivates, etc.).

To determine frequencies of different MRI patterns of tuberculous spondylitisin a public sector hospital in Karachi. This descriptive multidisciplinary case series study was done from October 25, 2011 to May 28, 2012 in Radiology Department and Department of Medicine in the Jinnah Postgraduate Medical Center Karachi. MRI scans (dorsal / lumbosacral spine) of the Patients presenting with backache in Medical OPD, were performed in Radiology Department. Axial and sagittal images of T1 weighted, T2 weighted and STIR sequences of the affected region were taken. A total of 140 patients who were diagnosed as having tuberculous spondylitis were further evaluated and analyzed for having different patterns of involvement of the spine and compared with similar studies. Among frequencies of different MRI pattern of tuberculous spondylitis, contiguous vertebral involvement was 100%, discal involvement 98.6%, paravertebral abscess 92.1% cases, epidural abscess 91.4%, spinal cord / thecal sac compression 89.3%, vertebral collapse 72.9%, gibbus deformity 42.9% and psoas abscess 36.4%. Contiguous vertebral involvement was commonest MRI pattern, followed by disk involvement, paravertebral & epidural abscesses, thecal sac compression and vertebral collapse.

An 8-year-old male red kangaroo (Macropus rufus) was evaluated with a 2-week history of vomiting and anorexia. Four days prior, the patient became refractory to medical management. The kangaroo was admitted for diagnostic testing and treatment including whole body CT, blood work, and emergency laparotomy. CT findings of a severely enlarged stomach, splenic displacement, and a whirl sign were indicative of mesenteric volvulus with gastric dilatation-volvulus (GDV). Contrast enhancement of abdominal viscera suggested intact arterial blood supply; however, compression of the caudal vena cava and portal vein indicated venous obstruction. Results of preoperative blood work suggested biliary stasis without evidence of inflammation. Additionally, a tooth root abscess was diagnosed on the basis of results of CT. Exploratory laparotomy confirmed the diagnosis of mesenteric volvulus and GDV. The volvuli were corrected by clockwise derotation, and a gastropexy was performed. Tissue samples were obtained from the spleen and liver for evaluation. The kangaroo recovered from surgery, and the abscessed tooth was extracted 6 days later. Eight days after initial evaluation, the kangaroo was discharged. In the present report, the CT whirl sign was used to diagnose volvulus of the abdominal viscera, which suggests that this diagnostic indicator has utility in veterinary patients. Mesenteric volvulus with GDV was successfully treated in a nondomestic species. The tooth root abscess, a common condition in macropods, may explain the historic episodes of anorexia reported by the owner and may have contributed to the development of mesenteric volvulus and GDV in this kangaroo.

Chromobacterium violaceum (C. violaceum) is a facultative anaerobic gram-negative bacterium found in soil and water, especially in tropical and subtropical areas. Although infection in humans is rare, it is associated with significant morbidity. The bacterium is known for its resistance to multiple antimicrobials, and the possibility of relapse and reinfection. Presence of bacteremia, disseminated infection, and ineffective antimicrobial agents are predictors of mortality. We report the case of a previously healthy 11-year-old male with C. violaceum sepsis who was exposed to stagnant water. He presented with severe septic shock and developed multi-organ system failure. Initial presumptive diagnosis was staphylococcal infection secondary to presence of skin abscesses resulting in antibiotic coverage with vancomycin, clindamycin, nafcillin and ceftriaxone. He also had multiple lung and liver abscesses. Once C. violaceum was identified, he received meropenem and ciprofloxacin, and was later discharged on ertapenem and trimethoprim-sulfamethoxazole (TMP-SMX) to complete a total of six months of antibiotics. He was diagnosed with chronic granulomatous disease (CGD) and is currently on prophylactic TMP-SMX and itraconazole. He has not had any relapses since his initial presentation. This case highlights the importance of considering C. violaceum as a relevant human pathogen, and considering it early in temperate regions, particularly in cases of fulminant sepsis associated with multi-organ abscesses. Once C. violaceum is identified, appropriate antimicrobial therapy should be started promptly, and sufficient duration of treatment is necessary for successful therapy.

Management of breast abscess in lactating women remains controversial. During pregnancy, women may develop different kinds of benign breast lesions that could require a surgical incision performed under general anesthesia with consequent breastfeeding interruption. The purpose of this study was to prospectively evaluate the management of large breast abscesses with ultrasound-assisted drainage aiming at breastfeeding preservation. 34 lactating women with a diagnosis of unilateral breast abscess have been treated with an ultrasound (US)-assisted drainage of the abscess. A pigtail catheter was inserted into the fluid collection using the Seldinger technique under US guide and connected to a three stop way to allow drainage and irrigation of the cavity until its resolution. All procedures have been found safe and well tolerated. No recurrence was observed and breastfeeding was never interrupted. The described technique allows to avoid surgery and to preserve breastfeeding in well-selected patients with a safe, well-tolerated and cost-effective procedure.

Streptococcus anginosus (S. anginosus) is considered a friendly bug and is a one of many different bacteria that constitute the normal flora of the oral cavity. Nevertheless, it has been infrequently associated with more invasive infections, like lung abscess. It is extremely rare to have multisystemic involvement with S. anginosus group. We present a unique case of pulmonary and brain abscess due to S. anginosus in an immunocompetent patient.

The management of pancreatic leakage is important after pancreatic resection because such leakagge can be associated with additional complications. In this paper, we present a new therapy "irrigation with suction" after pancreatic surgery. The addition of suction permits the start of irrigation early after surgery and prevents severe post-operative complications. Between January 1995 and June 2003, 29 consecutive patients underwent surgical treatment of the pancreas for a variety of indications. Among them, 18 patients were treated with continuous irrigation with suction prophylactically. In these 29 patients, we did not encounter any additional complications such as intraabdominal hemorrhage or abscess formation. A representative case report demonstrates the application of this treatment. The irrigation with suction therapy was started on the first post-operative day after the pylorus-preserving pancreatoduodenectomy with left lobectomy of the liver. CT with irrigation of contrast reagent showed that the reagent did not spread to the uninvolved abdominal area, and the patient did not develop hemorrhage or abscess. It seems that continuous irrigation with suction therapy was effective in preventing additional serious complications after pancreatic resection.

Psoas abscess is a rare clinical disease of various origins. Most common causes include hematogenous spread of bacteria from a different primary source, spondylodiscitis or perforated intestinal organs. But rarely some abscesses are related to malignant metastatic disease. In this case report we present the case of a patient with known squamous cell carcinoma of the cervix treated with radio-chemotherapy three years prior. She now presented with a psoas abscess and subsequent complete inferior vena cava thrombosis, as well as duodenal and vertebral infiltration. The abscess was drained over a prolonged period of time and later was found to be a complication caused by metastases of the cervical carcinoma. Due to the massive extent of the metastases a Whipple procedure was performed to successfully control the local progress of the metastasis. As psoas abscess is an unspecific disease which presents with non-specific symptoms adequate therapy may be delayed due to lack of early diagnostic results. This case report highlights the difficulties of managing a malignant abscess and demonstrates some diagnostic pitfalls that might be encountered. It stresses the necessity of adequate diagnostics to initiate successful therapy. Reports on psoas abscesses that are related to cervix carcinoma are scarce, probably due to the rarity of this event, and are limited to very few case reports. We are the first to report a case in which an extensive and complex abdominal procedure was needed for local control to improve quality of life.

A 7year old girl infected with the zoonotic trematode, Fasciola gigantica is reported because of the extreme rarity of this condition in our region. Because of the overlap in symptomatology and radiological features, the more common amebic/pyogenic liver abscess in the initial hepatic migratory phase and later choledochal cyst/biliary ascariasis when the parasite was finally located in the extrahepatic bile ducts, were thought of delaying effective treatment. The diagnosis was confirmed only by surgical exploration. The characteristic contrast enhanced computed tomography scan features retrospectively identified were multiple clustered hypodense lesions in the liver with peripheral enhancement in the acute hepatic migratory phase, and periportal tracking in the previously affected areas of the liver with biliary dilatation and a linear hypointense lesion within the common bile duct in the chronic phase. Although a known association, she did not have eosinophilia. This child, who became symptomatic at the age of 5.5years, also appears to be one of the youngest patients reported with Fasciola gigantica. Copyright © 2015 Elsevier Inc. All rights reserved.

To determine the health and economic burdens of post-partum Staphylococcus aureus breast abscess. We conducted a matched cohort study (N = 216) in a population of pregnant women (N = 32,770) who delivered at our center during the study period from 10/1/03-9/30/10. Data were extracted from hospital databases, or via chart review if unavailable electronically. We compared cases of S. aureus breast abscess to controls matched by delivery date to compare health services utilization and mean attributable medical costs in 2012 United States dollars using Medicare and hospital-based estimates. We also evaluated whether resource utilization and health care costs differed between cases with methicillin-resistant and -susceptible S. aureus isolates. Fifty-four cases of culture-confirmed post-partum S. aureus breast abscess were identified. Breastfeeding cessation (41%), milk fistula (11.1%) and hospital readmission (50%) occurred frequently among case patients. Breast abscess case patients had high rates of health services utilization compared to controls, including high rates of imaging and drainage procedures. The mean attributable cost of post-partum S. aureus breast abscess ranged from $2,340-$4,012, depending on the methods and data sources used. Mean attributable costs were not significantly higher among methicillin-resistant vs. -susceptible S. aureus cases. Post-partum S. aureus breast abscess is associated with worse health and economic outcomes for women and their infants, including high rates of breastfeeding cessation. Future study is needed to determine the optimal treatment and prevention of these infections.

Recently, an atypical rough colony morphotype of Peptostreptococcus micros, a species which is found in ulcerating infections, including periodontitis, was isolated. The virulence of morphotypes alone and in combination with Prevotella intermedia and P. nigrescens was investigated both in vivo and in vitro. All strains tested induced abscesses containing fluid pus in a mouse skin model, and lesions caused by monocultures of the rough morphotype strains of P. micros were statistically significantly larger than those induced by the smooth morphotype strains. Inocula containing both morphotypes produced similar sized abscesses compared to mono-inocula containing the same bacterial load. Both Prevotella species induced small abscesses when inoculated alone, and when Pr. nigrescens was inoculated with one of the other strains, the abscesses were not significantly different from the abscesses induced by the mono-infections of this strain. Synergy, in terms of higher numbers of colony forming units (cfu) in the mixed inocula, was found for all combinations of the rough morphotypes of P. micros and both Prevotella spp. Pus from abscesses caused by combinations of Peptostreptococcus and Prevotella spp. transmitted the infection to other mice, but no abscesses were formed in mice inoculated with pus induced by mono-inocula. These results demonstrated synergic activity between both rough and smooth P. micros strains and oral Prevotella strains. The in-vitro co-culture experiments produced no evidence of growth stimulation. The effect of P. micros strains on the immune system was investigated by testing their ability to initiate luminol-dependent chemiluminescence of polymorphonuclear leucocytes in the presence and absence of human serum. In the latter, the rough morphotype strains initiated higher counts than the smooth morphotype strains. Further work is needed to elucidate the difference in virulence between the smooth and the rough morphotype cells of P. micros and the nature of the interaction with the Prevotella spp.

Injection-site vein loss and soft tissue abscesses associated with black tar heroin injection: A cross-sectional study of two distinct populations in USA.

Injection-site vein loss and skin abscesses impose significant morbidity on people who inject drugs (PWID). The two common forms of street heroin available in the USA include black tar and powder heroin. Little research has investigated these different forms of heroin and their potential implications for health outcomes. A multiple-choice survey was administered to a sample of 145 participants seeking services at reduction facilities in both Sacramento, CA and greater Boston, MA, USA. Multivariate regression models for reporting one or more abscesses in one year, injection-site veins lost in six months, and soft tissue injection. Participants in Sacramento exclusively used black tar (99%), while those in Boston used powder heroin (96%). Those who used black tar heroin lost more injection-site veins (β=2.34, 95% CI: 0.66-4.03) and were more likely to report abscesses (AOR=7.68, 95% CI: 3.01-19.60). Soft tissue injection was also associated with abscesses (AOR=4.68, 95% CI: 1.84-11.93). Consistent venous access (AOR: 0.088, 95% CI: 0.011-0.74) and losing more injection sites (AOR: 1.22, 95% CI: 1.03-1.45) were associated with soft tissue injection. Use of black tar heroin is associated with more frequent abscesses and more extensive vein loss. Poor venous access predisposes people who inject drugs to soft tissue injection, which may constitute a causal pathway between black tar heroin injection and abscess formation. The mechanisms by which black tar heroin contributes to vein loss and abscess formation must be further elucidated in order to develop actionable interventions for maintaining vein health and decreasing the abscess burden. Potential interventions include increased access to clean injection equipment and education, supervised injection facilities, opioid substitution therapy, and supply chain interventions targeting cutting agents.

Purpose: Portal vein embolization is performed to increase the future liver remnant before liver surgery in patients with liver malignancies. This study assesses the feasibility of a transsinusoidal approach for portal vein embolization (PVE) with the ethylene vinyl alcohol copolymer, Onyx. Methods: Indirect portography through contrast injection in the cranial mesenteric artery was performed in eight healthy pigs. Onyx was slowly injected through a microcatheter from a wedged position in the hepatic vein and advanced through the liver lobules into the portal system. The progression of Onyx was followed under fluoroscopy, and the extent of embolization was monitored by indirectmore » portography. The pigs were euthanized immediately (n = 2), at 7 days (n = 4), or at 21 days postprocedure (n = 2). All pigs underwent necropsy and the ex vivo livers were grossly and histopathologically analyzed. Results: Transsinusoidal PVE was successfully performed in five of eight pigs (63%). In 14 of 21 injections (67%), a segmental portal vein could be filled completely. A mean of 1.6 liver lobes per pig was embolized (range 1-2 lobes). There were no periprocedural adverse events. Focal capsular scarring was visible on the surface of two resected livers, yet the capsules remained intact. Histopathological examination showed no signs of recanalization or abscess formation. Mild inflammatory reaction to Onyx was observed in the perivascular parenchyma. Conclusions: The porcine portal vein can be embolized through injection of Onyx from a wedged position in the hepatic vein. Possible complications of transsinusoidal PVE and the effect on contralateral hypertrophy need further study.« less

2018-03-02

There are numerous causes of hepatic gas formation that range from serious pathologies to incidental findings, including mesenteric infarction, liver abscess, inflammatory bowel disease or minimally invasive hepatic interventions. We report a case of a 50-year-old man who was admitted to the emergency room after a car accident. The clinical examination and further diagnostics revealed a craniocerebral injury with a fracture of the skull, concomitant soft tissue lesions and subarachnoidal bleeding. Furthermore, a blunt thoracic trauma with hemopneumothorax due to rib fractures was treated with a chest tube. No obvious abdominal pathology was seen. While in the operating theatre for the surgical revision of the cranial soft tissue lesions, a femoral venous catheter was inserted without any complications. A routine ultrasound of the abdomen six hours after the trauma revealed unclear hepatic gas formation. A contrast-enhanced computer tomography (CT) scan of the abdomen was performed, and the gas formation was found to be localized within the left hepatic vein. Afterwards, there was no specific treatment of the hepatic venous gas formation, as no alterations of liver function or liver enzymes were seen. The further course of the patient was uneventful regarding the gas formation in the liver, and another ultrasound two days later revealed no further gas in the liver. The placement of a femoral venous catheter is a risk factor for gas formation in liver veins. No further treatment is needed in cases with stable liver function. To rule out serious pathologies, diagnostic findings (e.g., ultrasound, CT), clinical history and underlying diseases need to be analyzed carefully after the detection of intrahepatic gas formation. With contrast-enhanced CT, the localization of the gas and its potential causes might be detectable.

Treatment of Intra-abdominal Abscesses in Crohn’s Disease – A Nationwide Analysis of Patterns and Outcomes of Care

PubMed Central

Ananthakrishnan, Ashwin N; McGinley, Emily L

2013-01-01

Background Abdominal abscesses are a common complication in Crohn’s disease (CD). Percutaneous drainage of such abscesses has become increasingly popular and may deliver outcomes comparable to surgical treatment; however, such comparative data are limited from single center studies. There have been no nationally representative studies comparing different treatment modalities for abdominal abscesses. Methods We identified all adult CD-related non-elective hospitalizations from the Nationwide Inpatient Sample 2007 that were complicated by an intra-abdominal abscess. Treatment modality was categorized into 3 strata – medical treatment alone, percutaneous drainage, and surgery. We analyzed the nationwide patterns in the treatment and outcomes of each treatment modality and examined for patient demographic, disease, or hospital-related disparities in treatment and outcome. Results There were an estimated 3,296 hospitalizations for abdominal abscesses in patients with CD. Approximately 39% were treated by medical treatment alone, 29% with percutaneous drainage, and 32% with surgery with a significant increase in the use of percutaneous drainage since 1998 (7%). Co-morbidity burden, admission to a teaching hospital, and complicated Crohn’s disease (fistulae, stricture) were associated with non-medical treatment. Use of percutaneous drainage was more common in teaching hospitals. Mean time to percutaneous drainage and surgical treatment were 4.6 and 3.3 days respectively and early intervention was associated with significantly shorter hospitalization. Conclusions We describe the nationwide pattern in the treatment of abdominal abscesses and demonstrate an increase in the use of percutaneous drainage for the treatment of this subgroup. Early treatment intervention was predictive of shorter hospitalization. PMID:23392744

The periodontal abscess: a review.

PubMed

Herrera, D; Roldán, S; Sanz, M

2000-06-01

The periodontal abscess is a frequent periodontal condition in which periodontal tissues may be rapidly destroyed. Its importance is based on the possible need of urgent care, the affectation of tooth prognosis, and the possibility of infection spreading. There is scant information in the scientific literature regarding this condition and most of it has been published as case reports and text books, where conclusions are not evidence-based, but rather empirical observations made by recognised clinicians. The aim of this review was to critically analyse all available information on this subject in the dental and medical literature, including information on its prevalence, proposed etiologies and pathogenesis, diagnosis, microbiology and treatment alternatives. The periodontal abscess is the 3rd most frequent dental emergency, and it is specially prevalent among untreated periodontal patients and periodontal patients during maintenance. Different etiologies have been proposed, and 2 main groups can be distinguished, depending on its relation with periodontal pockets. In the case of a periodontitis-related abscess, the condition may appear as an exacerbation of a non-treated periodontitis or during the course of periodontal therapy. In non-periodontitis related abscesses, impaction of foreign objects, and radicular abnormalities are the 2 main causes. The abscess microflora seems to be similar to that of adult periodontitis, and it is dominated by gram-negative anaerobic rods, including well-known periodontal pathogens. Complications and consequences include tooth loss and the spread of the infection to other body sites. Diagnosis and treatment is mainly based on empiricism, since evidence-based data are not available. The role of systemic antibiotics, in the treatment of periodontal abscesses, is especially controversial.

Valine and lactate have been recognized as important metabolic markers to diagnose brain abscess by means of MRS. However, in vivo unambiguous detection and quantification is hampered by macromolecular contamination. In this work, MEGA-PRESS difference editing of valine and lactate is proposed. The method is validated in vitro and applied for quantitative in vivo experiments in one healthy subject and two brain abscess patients. It is demonstrated that with this technique the overlapping lipid signal can be reduced by more than an order of magnitude and thus the robustness of valine and lactate detection in vivo can be enhanced. Quantification of the two abscess MEGA-PRESS spectra yielded valine/lactate concentration ratios of 0.10 and 0.27. These ratios agreed with the concentration ratios determined from concomitantly acquired short-T E PRESS data and were in line with literature values. The quantification accuracy of lactate (as measured with Cramér-Rao lower bounds in LCModel processing) was better for MEGA-PRESS than for short-T E PRESS in all acquired in vivo datasets. The Cramér-Rao lower bounds of valine were only better for MEGA-PRESS in one of the two abscess cases, while in the other case coediting of isoleucine confounded the quantification in the MEGA-PRESS analysis. MEGA-PRESS and short-T E PRESS should be combined for unambiguous quantification of amino acids in abscess measurements. Simultaneous valine/lactate MEGA-PRESS editing might benefit the distinction of brain abscesses from tumors, and further categorization of bacteria with reasonable sensitivity and specificity.

The relationship between chronic pancreatitis (CP) and subsequent pyogenic liver abscess (PLA) is not well understood. We investigated the risk of PLA in patients with CP using inpatient claims data from the Taiwan National Health Insurance Program for the period 2000-2010. We identified 17,810 patients with chronic pancreatitis (CP group) and 71,240 patients without CP (non-CP group). Both cohorts were followed until a diagnosis of PLA, until they were censored from the study because of loss to follow-up, death, or termination of insurance, or until the study cut-off date of 31 December 2011. Incidence and risk factors for development of PLA, and the effects of comorbidities, were assessed. The incidence of PLA in the CP group was 12.9 times that in the non-CP group (38.3 vs. 2.89 events per 1000 person-years; 95% confidence interval [CI], 10.5-15.8). After adjusting for age, sex, and the comorbidities of hypertension, diabetes, hyperlipidemia, cerebral vascular accident, cirrhosis, heart failure, chronic obstructive pulmonary disease, chronic kidney disease, cancer, alcoholism, other diseases of the pancreas, cholecystitis, and cholelithiasis and other disorders of the biliary tract and endoscopic insertion of stent (tube) into the bile duct, the risk of PLA remained higher among CP patients than among the comparison cohort (adjusted hazard ratio, 6.40; 95% CI, 4.83-8.49). CP patients with five or more comorbidities had a significantly higher risk of PLA (adjusted hazard ratio, 24.9; 95% CI, 18.3-33.8). CP was associated with increased risk of subsequent PLA. The risk of PLA was higher in patients with five or more comorbidities.

The strong association between penetrating colon injuries and intra-abdominal abscess (IAA) formation is well established and attributed to high colon bacterial counts. Since trauma patients are rarely fasting at injury, stomach and small bowel colony counts are also elevated. We hypothesized that there is a synergistic effect of increased IAA formation with concomitant stomach and/or colon injuries when compared to small bowel injuries alone. Consecutive patients at a level one trauma center with penetrating small bowel (SB), stomach (S), and/or colon (C) injuries from 1996 to 2012 were reviewed. Logistic regression determined associations with IAA, adjusting for age, gender, Injury Severity Score (ISS), admission Glasgow Coma Score, transfusions, and concurrent pancreas or liver injury. A total of 1518 patients (91% male, ISS = 15.9 ± 8.4) were identified: 496 (33%) SB, 231 (15%) S, 288 (19%) C, 40 (3%) S + SB, 69 (5%) S + C, 338 (22%) C + SB, and 56 (4%) S + C + SB. 148 (10%) patients developed IAA: 4 per cent SB, 9 per cent S, 10 per cent C, 5 per cent S + SB, 22 per cent S + C, 13 per cent C + SB, and 25 per cent S + C + SB. Multiple logistic regression demonstrated that ISS, 24 hour blood transfusions, and concomitant pancreatic or liver injuries were associated with IAA. Compared with reference SB, S or S + SB injuries were no more likely to develop IAA. However, S + C, SB + C, and S + C + SB injuries were significantly more likely to have IAA. In conclusion, combined stomach + colon, small bowel + colon, and stomach, colon, + small bowel injuries have a synergistic effect leading to increased IAA formation after penetrating injuries. Heightened clinical suspicion for IAA formation is necessary in these combined hollow viscus injury patients.

Klebsiella pneumoniae liver abscess (KPLA) has emerged as an endemic disease in Taiwan, and its prevalence has been increasing in east Asian countries in the past three decades. The utilization of healthcare resources associated with KPLA is assumed to be substantial, and may be of future concern. This study investigated the clinical characteristics and economic burden of KPLA in Taiwan in 2011 and 2012. Adult patients with KPLA were identified retrospectively in a tertiary medical center in Taiwan from January 2011 to December 2012. The clinical characteristics, total and daily hospitalization expenditure, and the risk factors for the costs of KPLA were analyzed. Among patients with KPLA, the median cost was $5290.80 in US dollars, and the mean cost was $6337.50 ± $4363.40. Length of hospital stay was the only independent risk factor for the high total hospitalization expenditure. The duration of antibiotic use was nearly the same as the length of hospital stay. The prolonged stay in the general ward (≥21 days) also contributed to the high total cost of hospitalization. The independent risk factors for the high average daily cost of hospitalization were a higher Charlson Comorbidity Index and the requirement of intensive care on admission. The current study is the first to demonstrate the high economic burden resulting from KPLA in a medical center in Taiwan. Standardizing the treatment protocol for KPLA inpatients and introducing an outpatient parenteral antimicrobial therapy center to reduce the length of stay may reduce costs, whereas development of a vaccine may be necessary to tackle endemic KPLA in the future.

Research highlights: {yields} ILY leads to the accumulation of [Ca{sup 2+}]i in the nucleus in HuCCT1 cells. {yields} ILY induced activation of NFAT1 through a calcineurin-dependent pathway. {yields} Calcineuri/NFAT pathway is involved in EGR-1 expression in response to ILY treatment. -- Abstract: Intermedilysin (ILY) is a cholesterol-dependent cytolysin produced by Streptococcus intermedius, which is associated with human brain and liver abscesses. Although intrahepatic bile duct cells play a valuable role in the pathogenesis of liver abscess, the molecular mechanism of ILY-treated intrahepatic bile duct cells remains unknown. In this study, we report that ILY induced a nuclear accumulation of intracellularmore » calcium ([Ca{sup 2+}]i) in human cholangiocellular cells HuCCT1. We also demonstrate that 10 ng/ml ILY induced NFAT1 dephosphorylation and its nuclear translocation in HuCCT1 cells. In contrast to the result that ILY induced NF-{kappa}B translocation in human hepatic HepG2 cells, ILY did not affect NF-{kappa}B localization in HuCCT1 cells. Dephosphorylation and nuclear translocation of NFAT1 caused by ILY were prevented by [Ca{sup 2+}]i calcium chelator, BAPTA/AM, and calcineurin inhibitors, cyclosporine A and tacrolimus. ILY induced early growth response-1 (EGR-1) expression and it was inhibited by the pre-treatment with cyclosporine A, indicating that the calcineurin/NFAT pathway was involved in EGR-1 expression in response to ILY. ILY-induced calcineurin/NFAT1 activation and sequential EGR-1 expression might be related to the pathogenesis of S. intermedius in human bile duct cells.« less

To assess whether chronic glycemic control and stress-induced hyperglycemia, determined by the gap between admission glucose levels and A1C-derived average glucose (ADAG) levels adversely affects outcomes in diabetic patients with pyogenic liver abscess (PLA). Clinical, laboratory, and multi-detector computed tomography (MDCT) findings of 329 PLA patients (2004-2010) were retrospectively reviewed. HbA1C levels were used to determine long-term glycemic control status, which were then converted to estimated average glucose values. For the gap between admission glucose levels and ADAG levels, we used receiver operating characteristic (ROC) curve to determine the optimal cut-off values predicting adverse outcomes. Univariate and multivariate logistic regressions were used to identify predictors of adverse outcomes. Diabetic PLA patients with poorer glycemic control had significantly higher Klebsiella pneumoniae (KP) infection rates, lower albumin levels, and longer hospital stays than those with suboptimal and good glycemic control. The ROC curve showed that a glycemic gap of 72 mg/dL was the optimal cut-off value for predicting adverse outcomes and showed a 22.3% relative increase in adverse outcomes compared with a glycemic gap<72 mg/dL. Multivariate analysis revealed that an elevated glycemic gap≥72 mg/dL was important predictor of adverse outcomes. A glycemic gap≥72 mg/dL, rather than admission hyperglycemia or chronic glycemic control, was significantly correlated with adverse outcomes in diabetic PLA patients. Poorer chronic glycemic control in diabetic PLA patients is associated with high incidence of KP infection, hypoalbuminemia and longer hospital stay.

Newly diagnosed breast abscesses are generally treated as a medical emergency that may necessitate immediate interventional treatment. At our institution, there is no in-house after-hours coverage for breast ultrasonography. We could find no peer-reviewed studies on the cost-effectiveness or clinical management impact of on-call ultrasound technologist coverage for imaging of breast abscesses. The purposes of this study were to determine the incidence of breast abscess in patients with clinical findings highly suggestive of abscess, identify clinical factors associated with breast abscess in such patients, and determine the impact of after-hours emergent or urgent breast ultrasonography on the clinical management of breast abscesses in both outpatients and inpatients. We retrospectively reviewed 100 after-hours breast ultrasound studies performed at our tertiary care center from 2011 to 2015 for evaluation of a suspected breast abscess. Only 26% of our patients with clinically suspected abscess ultimately had a confirmed abscess. Factors associated with breast abscess were a palpable abnormality and a history of breast surgery within the eight weeks before presentation. After-hours diagnosis of an abscess was associated with after-hours clinical intervention. Of the 74 patients in whom after-hours ultrasound imaging showed no evidence of abscess, only three patients underwent after-hours drainage. Our findings support overnight and weekend breast ultrasound coverage in large tertiary care centers. PMID:29473859

We herein report the case of a patient demonstrating a lung abscess with acute empyema which improved after performing pnemumonotomy and lung abscess drainage. A 60-year-old male was referred to our hospital to receive treatment for a lung abscess with acute empyema. At surgery, the lung parenchyma was slightly torn with pus leakage. After drainage of lung abscess by enlarging the injured part, curettage in the thoracic cavity and decortication were performed. The postoperative course was uneventful. Direct drainage of an abscess into the thoracic cavity is thought to be a choice for the treatment of lung abscesses.

Patients commonly present to emergency rooms and primary care clinics with cellulitic skin infections with or without abscess formation. In military operational units, non-physician medical personnel provide most primary and initial emergency medical care. The objective of this study was to determine if, after minimal training, Army physician assistants and medics could use portable ultrasound (US) machines to detect superficial soft tissue abscesses. This was a single-blinded, randomized, prospective observational study conducted over the course of 2 days at a military installation. Active duty military physician assistants and medics with little or no US experience were recruited as participants. They received a short block of training on abscess detection using both clinical examination skills (inspection/palpation) and US examination. The participants were then asked to provide a yes/no answer regarding abscess presence in a chicken tissue model. Results were analyzed to assess the participants' abilities to detect abscesses, compare the diagnostic accuracy of their clinical examinations with their US examinations, and assess how often US results changed treatment plans initially on the basis of clinical examination findings alone. 22 participants performed a total of 220 clinical examinations and 220 US scans on 10 chicken tissue abscess models. Clinical examination for abscess detection yielded a sensitivity of 73.5% (95% confidence interval [CI], 65.3-80.3%) and a specificity of 77.2% (95% CI, 67.4-84.9%), although US examination for abscess detection yielded a sensitivity of 99.2% (95% CI, 95.4-99.9%) and a specificity of 95.5% (95% CI, 88.5-98.6%). Clinical examination yielded a diagnostic accuracy of 75.0% (95% CI, 68.9-80.3) although US examination yielded a diagnostic accuracy of 97.7% (95% CI, 94.6-99.2%), a difference in accuracy of 22.7% favoring US (p < 0.01). US changed the diagnosis in 56 of 220 cases (25.4% of all cases, p = 0.02). Of these 56 cases, US led to the correct diagnosis 53 of 56 times (94.6%). Non-physician military medical providers can be trained in a very brief period to use US to detect superficial soft tissue abscesses with excellent accuracy.

Acute apical abscesses and cellulitis are severe endodontic diseases caused by opportunistic bacteria with possible co-infection with latent herpesviruses. The objectives of this study are to identify herpesviruses, including human cytomegalovirus (HCMV), Epstein-Barr virus (EBV), herpes simplex virus-1 (HSV-1) and Varicella zoster virus (VZV), in patients (n=31) presenting with acute apical abscesses and cellulitis of endodontic origin. Primary and nested polymerase chain reaction (PCR) was conducted using virus-specific primers and DNA isolated from cell-free abscess fluid. From patients exhibiting concurrent spontaneous pain (n=28), nine abscesses contained HCMV, two abscesses contained EBV, one abscess contained HSV-1, and no abscesses contained VZV. Control PCR using genomic or recombinant templates demonstrated detection limits to a single genomic copy of HCMV, 100 genomic copies for EBV, and 1-10 copies for HSV-1, with no cross-amplification between herpesviral DNA targets. Nested PCR was required for detection of herpesviral DNA in the abscess specimens, indicating that these viruses were present in low copy number. Filtration of abscess specimens and virus transfer experiments using human fibroblastic MRC-5 cells confirmed the presence of HCMV particles in several abscess specimens. We conclude that herpesviruses are present, but not required for development of acute apical abscesses and cellulitis of endodontic origin. PMID:19166769

Although breast abscess is a serious uncommon complication of mastitis with high morbidity rate, there is a lack of high-quality randomized trial to demonstrate the best treatments. We reported a novel way of applying negative suction drain through a mini periareolar incision. We retrospectively analyzed and compared the clinical characteristics of 62 patients with lactational breast abscess in our department from August 2012 to April 2015. Thirty-two patients went through traditional incision and drainage (Group A) and 30 patients were placed on negative suction drain through mini periareolar incision (Group B). There is no significant difference between the two groups in terms of age, white blood cell (WBC) count, size of the abscess cavity, and positive rate of Staphylococcus aureus (SA) or methicillin-resistant Staphylococcus aureus (MRSA). Patients in Group B had a shorter hospitalized stay (p = 0.003) and had a higher rate of continuation of breastfeeding (p < 0.005). Applying drain with negative suction pressure through a mini periareolar incision is an effective modality for treating lactational breast abscess and maintaining breastfeeding.

To evaluate the periodontal abscess as a possible oral clinical diagnostic criteria for the diagnosis of diabetes mellitus in the elderly. In this clinical outpatient department, cross-sectional study of 84 months, 143 212 subjects between the ages of 40 and 84 years were screened for the presence of periodontal abscess. Relevant medical and dental histories were recorded using a questionnaire. The subjects who fulfilled the inclusion criteria of undiagnosed diabetes mellitus, presence of periodontal abscess, and absence of other systemic disease were referred for laboratory diagnosis of diabetes mellitus (HbA1c). The subjects tested positive for the diabetes were noted, statistical evaluation was undertaken to correlate between undiagnosed diabetes mellitus and periodontal abscess. It was found out that 0.05% undiagnosed diabetes was noted among the 143 212 patients. Among the 143 212 subjects, 1352 met the inclusion criteria having periodontal abscess. Mean age of the participants was 57 ± 14.2 years. Among the 1352 subjects with periodontal abscess: 793 (58.65%) subjects had increased HbA1c (≥6.5% or 47.5 mmol/mol or 7.8 mmol/L); 559 (41.35%) individuals reported to have normal HbA1c (≤6.5% or 47.5 mmol/mol or 7.8 mmol/L). The difference was found to be statistically significant. Periodontal abscess can be considered as possible oral clinical diagnostic criteria for the diagnosis of diabetes mellitus. Elderly individuals visiting dental clinics need to be given due attention to find out the possibility of having this systemic condition. Medical fraternities are advised to consider oral health parameters in the evaluation of the medical status of elderly individuals. © 2016 John Wiley & Sons Australia, Ltd.

The treatment of complex liver injuries remains a challenge. Nonoperative treatment for such injuries is increasingly being adopted as the initial management strategy. We reviewed our experience, at a University teaching hospital, in the nonoperative management of grade IV liver injuries with the intent to evaluate failure rates; need for angioembolization and blood transfusions; and in-hospital mortality and complications. This is a retrospective analysis conducted at a single large trauma centre in Brazil. All consecutive, hemodynamically stable, blunt trauma patients with grade IV hepatic injury, between 1996 and 2011, were analyzed. Demographics and baseline characteristics were recorded. Failure of nonoperative management was defined by the need for surgical intervention. Need for angioembolization and transfusions, in-hospital death, and complications were also assessed Eighteen patients with grade IV hepatic injury treated nonoperatively during the study period were included. The nonoperative treatment failed in only one patient (5.5%) who had refractory abdominal pain. However, no missed injuries and/or worsening of bleeding were observed during the operation. None of the patients died nor need angioembolization. No complications directly related to the liver were observed. Unrelated complications to the liver occurred in three patients (16.7%); one patient developed a tracheal stenosis (secondary to tracheal intubation); one had pleural effusion; and one developed an abscess in the pleural cavity. The hospital length of stay was on average 11.56 days. In our experience, nonoperative management of grade IV liver injury for stable blunt trauma patients is associated with high success rates without significant complications.

An odontogenic cause of a lung abscess can easily be overlooked. A 61-year-old man presented at the emergency department with a productive cough and dyspnoea. He was admitted to the pulmonary ward with a suspected odontogenic lung abscess. A thorax CT scan confirmed the diagnosis 'lung abscess', following which the dental surgeon confirmed that the lung abscess probably had an odontogenic cause. The patient made a full recovery following a 6-week course of antibiotics, and he received extensive dental treatment. Poor oral hygiene can be a cause of a lung abscess. A patient with a lung abscess can be treated successfully with a 6-week course of antibiotics; however, if the odontogenic cause is not recognised the abscess can recur.

Lingual abscesses in three dogs.

Lingual abscessation is a rare condition in dogs. Very little information is available on the diagnosis and treatment of lingual abscesses in the major surgical textbooks and current veterinary literature. The common clinical signs of lingual abscesses are macroglossia, hypersalivation and a reluctance to open the mouth, but these can vary depending on the time course of the disease and the location of the abscess. This article presents three cases of tongue abscess in the dog outlining treatment and outcomes. A thorough diagnostic work up, consisting of anamnesis, clinical and haematological examinations, oral inspection under sedation and the use of diagnostic imaging techniques should be mandatory before surgical exploration of the abscess. Surgery is followed by drainage and systemic antibiotics, complemented by systemic fluid support and pain management. Conservative management of lingual abscesses can be fatal. Sharp trauma from an unknown object is suspected to be the underlying cause for the abscesses in the present cases.

Treatments for breast abscesses in breastfeeding women.

The benefits of breastfeeding are well known, and the World Health Organization recommends exclusive breastfeeding for the first six months of life and continuing breastfeeding to age two. However, many women stop breastfeeding due to lactational breast abscesses. A breast abscess is a localised accumulation of infected fluid in breast tissue. Abscesses are commonly treated with antibiotics, incision and drainage (I&D) or ultrasound-guided needle aspiration, but there is no consensus on the optimal treatment. To assess the effects of different treatments for the management of breast abscesses in breastfeeding women. We searched the Cochrane Pregnancy and Childbirth Group's Trial Register (27 February 2015). In addition we searched African Journals Online (27 February 2015), Google Scholar (27 February 2015), ProQuest Dissertations and Theses Databases (27 February 2015) and the WHO International Clinical Trials Registry Platform (ICTRP) search portal (27 February 2015). We also checked reference lists of retrieved studies and contacted experts in the field as well as relevant pharmaceutical companies. Randomised controlled trials (RCTs) investigating any intervention for treating lactational breast abscesses compared with any other intervention. Studies published in abstract form, quasi-RCTs and cluster-RCTs were not eligible for inclusion. Two review authors independently assessed studies for inclusion, assessed risk of bias and extracted data. Data were checked for accuracy. We included six studies. Overall, trials had an unclear risk of bias for most domains due to poor reporting. Two studies did not stratify data for lactational and non-lactational breast abscesses, and these studies do not contribute to the results. This review is based on data from four studies involving 325 women. Needle aspiration (with and without ultrasound guidance) versus incision and drainage (I&D) Mean time (days) to complete resolution of breast abscess (three studies) - there was substantial heterogeneity among these data (Tau(2) = 47.63, I(2) = 97%) and a clear difference between subgroups (with or without ultrasound guidance; Chi(2) = 56.88, I(2) = 98.2%, P = < 0.00001). We did not pool these data in a meta-analysis. Two studies excluded women who had treatment failure when they calculated the mean time to complete resolution. One study found that the time to complete resolution of breast abscess favoured needle aspiration over I&D (mean difference (MD) -6.07; 95% confidence interval (CI) -7.81 to -4.33; n = 36), but excluded 9/22 (41%) women in the needle aspiration group due to treatment failure. Another study reported faster resolution in the needle aspiration group (MD -17.80; 95% CI -21.27 to -14.33; n = 64) but excluded 6/35 (17%) women in the needle aspiration group due to treatment failure. A third study also reported that needle aspiration was associated with a shorter time to complete resolution of breast abscess (MD -16.00; 95%CI -18.73 to -13.27; n = 60); however, the authors did not indicate the number of women who were lost to follow-up for either group, and it is unclear how many women contributed to this result. Considering the limitations of the available data, we do not consider the results to be informative. Continuation of breastfeeding, after treatment (success): results favoured the needle aspiration group, but we did not pool data from the two studies because of substantial unexplained heterogeneity (I(2) = 97%). One study reported that women in the needle aspiration group were more likely to continue breastfeeding (risk ratio (RR) 2.89; 95% CI 1.64 to 5.08; n = 60), whereas the other study found no clear difference (RR 1.09; 95% CI 0.97 to 1.22 n = 70). Treatment failure was more common among women treated with needle aspiration compared to those who underwent I&D (RR 16.12; 95% CI 2.21 to 117.73; two studies, n = 115, low quality evidence). In one study, treatment with needle aspiration failed in 9/22 women who subsequently underwent I&D to treat their breast abscess. In another study, treatment with needle aspiration failed in 6/35 women, who subsequently underwent I&D. All abscesses in the I&D group were successfully treated.The included studies provided limited data for the review's secondary outcomes. No data were reported for adverse events. One study (60 women) reported that women in the needle aspiration group were more satisfied with their treatment than women who received I&D to treat their breast abscesses. Incision and drainage (I&D) with or without antibioticsOne study (150 women) compared the value of adding a broad-spectrum cephalosporin (single dose or a course of treatment) to women who underwent I&D for breast abscesses.The mean time to resolution of breast abscess was reported as being similar in all groups (although women with infection were excluded). Mean time to resolution for women who received a course of antibiotics was reported as 7.3 days, 6.9 days for women who received a single dose of antibiotics and 7.4 days for women who did not receive antibiotics. Standard deviations, P values and CIs were not reported and prevented further analysis. No data were reported for any continuation of breastfeeding after treatment (success). For treatment failure, there was no clear difference between the groups of women who received antibiotics (either a single dose or a course of antibiotics) and those who did not (RR 1.00; 95% CI 0.36 to 2.76).Included studies rarely reported this review's secondary outcomes (including adverse events). For post-operative complications/morbidity, there was no difference in the risk of wound infections between the antibiotics and no antibiotics groups (RR 0.58; 95% CI 0.29 to 1.17), irrespective of whether women received a single dose or a course of antibiotics. There is insufficient evidence to determine whether needle aspiration is a more effective option to I&D for lactational breast abscesses, or whether an antibiotic should be routinely added to women undergoing I&D for lactational breast abscesses. We graded the evidence for the primary outcome of treatment failure as low quality, with downgrading based on including small studies with few events and unclear risk of bias.

Appendicitis is a common surgical emergency in pediatric patients, and broad-spectrum antibiotic therapy is warranted in their care. A simplified once-daily regimen of ceftriaxone and metronidazole (CTX plus MTZ) is cost effective in perforated patients. The goal of this evaluation is to compare a historic regimen of cefoxitin (CFX) in nonperforated cases and ertapenem (ERT) in perforated and abscessed cases with CTX plus MTZ for all cases in terms of efficacy and cost. A retrospective review compared outcomes of nonperforated, perforated, and abscessed cases who received the historic regimen or CTX plus MTZ. Length of stay, time to afebrile, time to full feeds, postoperative abscess, and wound infection rates, inpatient readmissions, and antibiotic costs were evaluated. There were a total of 841 cases reviewed (494 nonperforated, 247 perforated, and 100 abscessed). Overall, the CTX plus MTZ group had a shorter time to afebrile (P < .001). Treatment groups did not differ in length of stay. Postoperative abscess rates were similar between groups (4.1% vs 3.3%, not significant). Other postoperative complications were similar between groups. Total antibiotic cost savings were over $110 000 during the study period (from November 2010 to June 2013). Both CFX and/or ERT and CTX plus MTZ result in low abscess and complication rates, suggesting both are effective strategies. Treatment with CTX plus MTZ results in a shorter time to afebrile, while also providing significant antibiotic cost savings. Ceftriaxone plus MTZ is a streamlined, cost-effective regimen in the treatment of nonperforated, perforated, and abscessed appendicitis. © The Author 2015.

Objectives Non-operative management has become the treatment of choice in the majority of liver injuries. The aim of this study was to assess the changes in primary treatment and outcomes in a single Dutch Level 1 trauma centre with wide experience in angio-embolisation (AE). Methods The prospective trauma registry was retrospectively analysed for 7-year periods before (Period 1) and after (Period 2) the introduction of AE. The primary outcome was the failure rate of primary treatment defined as liver injury-related death or re-bleeding requiring radiologic or operative (re)interventions. Secondary outcomes were liver injury-related intra-abdominal complications. Results Despite an increase in high-grade liver injuries, the incidence of primary non-operative management more than doubled over the two periods, from 33% (20 of 61 cases) in Period 1 to 72% (84 of 116 cases) in Period 2 (P < 0.001). The failure rate of primary treatment in Period 1 was 18% (11/61), compared with 11% (13/116) in Period 2 (P = 0.21). Complication rates were 23% (14/61) and 16% (18/116) in Periods 1 and 2, respectively (P = 0.22). Liver-related mortality rates were 10% (6/61) and 3% (4/116) in Periods 1 and 2, respectively (P = 0.095). The increase in the frequency of non-operative management was even higher in high-grade injuries, in which outcomes were improved. In high-grade injuries in Periods 1 and 2, failure rates decreased from 45% (9/20) to 20% (11/55) (P = 0.041), liver-related mortality decreased from 30% (6/20) to 7% (4/55) (P = 0.019) and complication rates fell from 60% (12/20) to 27% (15/55) (P = 0.014). Liver infarction or necrosis and abscess formation seemed to occur more frequently with AE. Conclusions Overall, liver-related mortality, treatment failure and complication rates remained constant despite an increase in non-operative management. However, in high-grade injuries outcomes improved after the introduction of AE. PMID:21492335

Tuberculous temporal brain abscess mimicking otogenic pyogenic abscess.

2009-01-01

Tuberculous brain abscess is a rare manifestation of central nervous system tuberculosis. We report the case of a tuberculous temporal lobe abscess in a 14-year-old female child that mimicked an otogenic pyogenic brain abscess. The patient had no prior history of tuberculosis. She had chronic otitis media and presented with signs of raised intracranial tension. Radiological imaging was suggestive of an acute pyogenic left temporal lobe abscess. A left temporal craniotomy was performed and the abscess was completely excised. Histological examination was consistent with a chronic abscess, and bacterial cultures were negative. A left radical mastoidectomy was also carried out. However, she presented with repeated abscess formation at the same site over the next 8 weeks, which was refractory to surgical therapy and broad-spectrum antibiotic administration. Furthermore, the purulent exudate showed strong positivity in the PCR test for tubercular bacilli. After administration of antituberculous treatment, she showed gradual clinical and radiological improvement. At follow-up after 2 years, she is asymptomatic. CT imaging at 2 years showed total resolution of abscess. Tuberculous abscess in the temporal lobe following otogenic infection has not been reported in the pediatric population. Although rare, the possibility of tuberculous etiology should be borne in mind as a differential diagnosis of acute abscess of otogenic origin, especially in endemic areas where the incidence of chronic otitis media as well as tuberculosis is high. The pathogenesis and treatment of tuberculous brain abscess in children is reviewed in light of the current literature on the subject. Copyright 2009 S. Karger AG, Basel.

Acute suppurative thyroiditis and recurrent abscess formation due to third and fourth branchial anomalies typically present in children. However, thyroid abscesses in branchial anomalies may occur in adulthood as well. Failure to recognize and delayed drainage of a neck abscess may lead to a fulminant life-threatening outcome. This is a retrospective case series. The study group comprised all patients presenting over a 12-month period from January to December 2012 with thyroid abscesses and a branchial cleft anomaly in two centres, one adult and the other paediatric. Patient demographics, clinical presentation, imaging, surgical management, definitive histology and outcomes were documented. Five patients were identified with a history of thyroid abscesses. Only one was a child (aged 9 years) with the other four being adults (aged 20, 34, 37 and 41 years). All patients had third or fourth left branchial cleft anomalies, presenting as suppurative thyroiditis with a left-sided thyroid abscess. Management options ranged from abscess drainage on initial presentation, primary thyroid lobectomy or delayed thyroid lobectomy following abscess drainage. Acute suppurative thyroidits and thyroid abscesses is not just a paediatric diagnosis but may present at any age. In both children and adults, a thyroid abscess almost always arises from branchial cleft anomalies. © 2014 Royal Australasian College of Surgeons.

Tuberculous brain abscess and subdural empyema in an immunocompetent child: Significance of AFB staining in aspirated pus

Tuberculous brain abscess and subdural empyema are extremely rare manifestations of central nervous system tuberculosis. Here, we report a case of an 11-year-old immunocompetent child who developed temporal lobe abscess and subdural empyema following chronic otitis media. A right temporal craniotomy was performed and the abscess was excised. The Ziehl Nielsen staining of the aspirated pus from the temporal lobe abscess yielded acid fast bacilli. Prompt administration of antituberculous treatment resulted in complete recovery of the child. Even though the subdural abscess was not drained, we presume that to be of tubercular aetiology. Ours is probably the first case of brain abscess and subdural empyema due to Mycobacterium tuberculosis reported in the same child. This case is being reported because of its rarity and to stress the importance of routine staining for tubercle bacilli in all cases of brain abscess, especially in endemic areas, as it is difficult to differentiate tuberculous from pyogenic abscess clinically as well as histopathologically.

to evaluate the epidemiological variables and diagnostic and therapeutic modalities related to hepatic trauma patients undergoing laparotomy in a public referral hospital in the metropolitan region of Vitória-ES. we conducted a retrospective study, reviewing charts of trauma patients with liver injuries, whether isolated or in association with other organs, who underwent exploratory laparotomy, from January 2011 to December 2013. We studied 392 patients, 107 of these with liver injury. The male: female ratio was 6.6 : 1 and the mean age was 30.12 years. Penetrating liver trauma occurred in 78.5% of patients, mostly with firearms. Associated injuries occurred in 86% of cases and intra-abdominal injuries were more common in penetrating trauma (p <0.01). The most commonly used operative technique was hepatorrhaphy and damage control surgery was applied in 6.5% of patients. The average amounts of blood products used were 6.07 units of packed red blood cells and 3.01 units of fresh frozen plasma. The incidence of postoperative complications was 29.9%, the most frequent being infectious, including pneumonia, peritonitis and intra-abdominal abscess. The survival rate of patients suffering from blunt trauma was 60%, and penetrating trauma, 87.5% (p <0.05). despite technological advances in diagnosis and treatment, mortality rates in liver trauma remain high, especially in patients suffering from blunt trauma in relation to penetrating one.

Corticosteroids and peritonsillar abscess formation in infectious mononucleosis.

PubMed

Hanna, Brendan C; McMullan, Ronan; Hall, Samuel J

2004-06-01

Peritonsillar abscess formation is an uncommon complication of infectious mononucleosis (IM). Early case reports implicated corticosteroids in the development of such abscesses, however, subsequent studies suggested that these drugs do not promote the formation of abscesses at several sites outside the central nervous system. It has recently been demonstrated that zwitterionic polysaccharides, in bacterial capsules, form complexes with CD4(+) T lymphocytes leading to abscess formation. A patient is presented who developed peritonsillar abscess a few days after initiation of corticosteroid therapy for IM; the medical literature was reviewed in respect of this subject. It appears that the occurrence of these abscesses in IM is not strongly linked to corticosteroid treatment. The authors, therefore, recommend that steroids should not be withheld from patients with severe IM on the basis that they may precipitate the development of peritonsillar abscess.

Twenty-eight odontogenic abscesses were examined for the presence of black-pigmented Bacteroides spp. Of the 28 samples, 26 were found to contain one or more species of black-pigmented Bacteroides. Abscesses were divided into three categories according to the tissue of origin: endodontal, periodontal, and pericoronal. Four abscesses which developed after extraction were also examined. It was found that Bacteroides endodontalis, a newly described species of asaccharolytic black-pigmented Bacteroides, was isolated almost exclusively from periapical abscesses of endodontal origin. B. intermedius proved to be the most frequently isolated species in all of the samples. B. gingivalis was present in all of the periodontal abscesses studied, as well as in two endodontal abscesses. B. melaninogenicus was recovered once from a pericoronal abscess. Precautions for the isolation of B. endodontalis are discussed. PMID:4030089

Splenic Abscess Associated with Endocarditis in a Patient on Hemodialysis: A Case Report

Splenic abscess is an unusual condition usually seen in immunocompromised patients or associated with intravenous drug abuses. Several conditions including trauma, immunodeficiency, corticosteroid and/or immunosuppressive therapy and diabetes mellitus have been listed under the predisposing factors for a splenic abscess. Splenic abscess in a patient on hemodialysis is a rare but life-threatening condition if not corrected. We describe a case of splenic abscess with bacterial endocarditis on maintenance hemodialysis. He had staphylococcal septicemia secondary to bacterial endocarditis at the mitral valve from the dialysis accesssite infection. Although hematologic seeding from endocarditis has been the predisposing factor for splenic abscess, we postulate that access-site infections may predispose hemodialysis patients to splenic abscess. Splenic abscess may be considered as one of the causes when patients on hemodialysis develop unexplained fever. PMID:15832007

Proctocolectomy with conventional ileostomy cures patients with severe ulcerative colitis but ileostomy appliances must be worn for the rest of their lives. The continent ileostomy, as devised by Kock, provides the patient with an intraabdominal ileal reservoir and a valve constructed by invaginating the efferent ileal segment into the reservoir. The patient empties his reservoir 2-3 times a day by inserting a catheter through the valve. Our experience with 14 patients is reported. The continent ileostomy was in most cases constructed as a second procedure after proctocolectomy. Minor postoperative complications, such as abscess, fistula or partial luxation of the valve were easily corrected. One patient who underwent proctocolectomy and simultaneous construction of a continent ileostomy died in acute liver failure due to a severe preexisting cirrhosis. All the other patients are continent for feces and gas and do not need external appliances. The construction of a continent ileostomy as a secondary procedure can be recommended in patients with proctocolectomy. It offers patients a life situation with differs only insignificantly from that of normal persons.

2016-10-01

The present study examined the histopathological and magnetic resonance imaging (MRI) features of pyogenic, brucella and tuberculous spondylitis (PS, BS and TS, respectively). A total of 22 PS, 20 BS and 20 TS patients were included in the study. Histopathological examination was used to assess the lesion structure and composition, and the MRI observation identified the lesion location and signal features. The following histopathological and MRI features were identified significantly more in patients with PS than in patients with BS and TS: Predominant neutrophil infiltration, abnormal intervertebral disk signal, lesions on the ventral and lateral sides of the vertebral bodies, and thick and irregular abscess walls. The following histopathological and MRI features were identified significantly more in patients with BS than in patients with PS and TS: Predominant lymphocyte infiltration, new bone formation, epithelioid granuloma, lesions on the ventral sides of the vertebral bodies, no, or very mild, vertebral body deformation, no abnormal paraspinal soft tissue signal, no intraosseous or paraspinal abscesses, and thin and irregular abscess walls. The following histopathological and MRI features were identified significantly more in patients with TS than in patients with BS and PS: Sequestrum, Langerhans giant cells, caseous necrosis, lesions primarily in the thoracic region and on the lateral sides of the vertebral bodies, no obvious intervertebral disk damage, obvious vertebral body deformation, abnormal paraspinal soft tissue signal, intraosseous or paraspinal abscesses, and thin and smooth abscess walls. In conclusion, it can be suggested that these significant differences in histopathological and MRI features between the three different types of spondylitis may contribute towards the differential diagnosis of the diseases.

Lung abscess predicts the surgical outcome in patients with pleural empyema

Objectives Most cases of pleural empyema are caused by pulmonary infections, which are usually combined with pneumonia or lung abscess. The mortality of patients with pleural empyema remains high (up to 20%). It also contributes to higher hospital costs and longer hospital stays. We studied pleural empyema with combined lung abscess to determine if abscess was associated with mortality. Methods From January 2004 to December 2006, we retrospectively reviewed 259 patients diagnosed with pleural empyema who received thoracscopic decortications of the pleura in a single medical center. We evaluated their clinical data and analyzed their chest computed tomography scans. Outcomes of pleural empyema were compared between groups with and without lung abscess. Results Twenty-two pleural empyema patients had lung abscesses. Clinical data showed significantly higher incidences in the lung abscess group of pre-operative leukocytosis, need for an intensive care unit stay and mortality. Conclusion Patients with pleural empyema and lung abscess have higher intensive care unit admission rate, higher mortality during 30 days and overall mortality than patients with pleural empyema. The odds ratio of lung abscess is 4.685. Physician shall pay more attention on high risk patient of lung abscess for early detection and management. PMID:20961413

Current trends in the diagnosis and treatment of tuboovarian abscess

DOE Office of Scientific and Technical Information (OSTI.GOV)

Landers, D.V.; Sweet, R.L.

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 polymicrobialmore » 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.« less

Human cytomegalovirus and Epstein-Barr virus type 1 in periodontal abscesses.

2004-04-01

Recent studies have linked herpesviruses to severe types of periodontal disease, but no information exists on their relationship to periodontal abscesses. The present study determined the presence of human cytomegalovirus (HCMV) and Epstein-Barr virus type 1 (EBV-1) in periodontal abscesses and the effect of treatment on the subgingival occurrence of these viruses. Eighteen adults with periodontal abscesses participated in the study. Subgingival samples were collected from each patient with sterile curettes from an abscess-affected site and a healthy control site. HCMV and EBV-1 were identified by polymerase chain reaction at the time of the abscess and at 4 months after surgical and systemic doxycycline therapy. HCMV was detected in 66.7% of periodontal abscess sites and in 5.6% of healthy sites (P=0.002). EBV-1 occurred in 72.2% of abscess sites but not in any healthy site (P<0.001). HCMV and EBV-1 co-infection was identified in 55.6% of the abscess sites. Posttreatment, HCMV and EBV-1 were not found in any study site. HCMV and EBV-1 genomes are commonly found in periodontal abscesses. These data favor a model in which a herpesvirus infection of the periodontium impairs the host defense and serves as a platform for the entrance of bacterial pathogens into gingival tissue with subsequent risk of abscess development.

In this case report, we present a 36-year-old woman with signs, symptoms and conventional imaging features of malignancy who underwent breast MRI. On diffusion-weighted imaging (DWI), profoundly low apparent diffusion coefficient values were a distinguishing sign of breast abscess from necrotic breast cancer, and helped manage the patient conservatively.

We present the first described case of invasive adenocarcinoma presenting as an abscess in a man. An 80-year-old diabetic man presented with symptoms typical of a breast abscess. The abscess failed to respond to percutaneous therapy and excision of breast abscess was performed. Histology revealed an invasive carcinoma. He went on to have a mastectomy. Histology should be obtained from breast abscesses not resolving within 2 months of initial percutaneous therapy. Histology could be obtained by ultrasound-guided fine-needle aspiration (FNA), core or vacuum assisted biopsy, or by formal incision and drainage.

We report FDG PET of two cases of cold abscess due to Mycobacterium tuberculosis. Case 1 had colon cancer; FDG PET showed high FDG uptake in the colon lesion and low uptake in the inguinal lesion. The latter was a tuberculous cold abscess confirmed by CT/MRI and biopsy. Case 2 received radiotherapy for lung cancer and presented with suspected vertebral metastasis. Further studies revealed tuberculosis of the vertebra and a tuberculous cold abscess in the iliopsoas muscle. FDG PET showed moderate uptake in the third lumbar spine and low uptake in the abscess center of iliopsoas lesion. Both tuberculous cold abscesses showed moderate FDG uptake in the capsule and low uptake in the center. These features are unique compared with non-tuberculous abscess and typical tuberculosis lesions, which are characterized by high FDG uptake. Pathologically, tuberculous cold abscess is not accompanied by active inflammatory reaction. Our findings suggested that the FDG uptake by tuberculous lesion varies according to the grade of inflammatory activity. The new diagnostic features of tuberculous cold abscess may be useful in the evaluation of such lesions by FDG PET.

2012-04-01

Although brain abscesses are frequently cryptogenic in origin, bacteria must reach the brain either by direct or hematogenous spread. Right-to-left shunts, caused either by intrapulmonary vascular malformations or congenital heart defects, may allow microorganisms to evade the normal host defenses in the lungs and lead to development of brain abscesses. Two patients recently presented with brain abscesses and were found to have conditions associated with right-to-left shunts. The diagnosis of brain abscess should prompt the clinician to consider right-to-left shunts as a possible predisposing condition for brain abscess.

A 68-year-old man, complaining of fever and puriform sputum, was referred to our hospital. A giant abscess was detected in the upper lobe of the right lung. Percutaneous drainage of a lung abscess was carried out. When the pus collected was cultured, Candida was 1+ and Escherichia coli was 2+. Later, it became difficult to control the abscess by drainage, and cavernostomy was selected. The contents of the abscess cavity were removed, and the cavity was opened, followed by exchange of gauze every day. For 14 months after cavernostomy, once-weekly gauze exchange was continued at the outpatient clinic to clean the abscess cavity. Finally, the abscess was filled with a free greater omentum flap, accompanied by microvascular anastomosis. In this way, the intractable lung abscess was successfully cured. Conventionally, surgical treatment, particularly cavernostomy, has been applied only to limited cases when dealing with a lung abscess. Our experience with the present case suggests that surgical treatment, including cavernostomy as one option, should also be considered when dealing with lung abscesses resisting medical treatment and causing compromised respiratory function. To enable maximum utilization of the greater omental flap, which is available in only a limited amount, it seems useful to prepare and graft a free omental flap making use of microvascular surgery.

Nonoperative management for patients with grade IV blunt hepatic trauma

PubMed Central

2012-01-01

Introduction The treatment of complex liver injuries remains a challenge. Nonoperative treatment for such injuries is increasingly being adopted as the initial management strategy. We reviewed our experience, at a University teaching hospital, in the nonoperative management of grade IV liver injuries with the intent to evaluate failure rates; need for angioembolization and blood transfusions; and in-hospital mortality and complications. Methods This is a retrospective analysis conducted at a single large trauma centre in Brazil. All consecutive, hemodynamically stable, blunt trauma patients with grade IV hepatic injury, between 1996 and 2011, were analyzed. Demographics and baseline characteristics were recorded. Failure of nonoperative management was defined by the need for surgical intervention. Need for angioembolization and transfusions, in-hospital death, and complications were also assessed Results Eighteen patients with grade IV hepatic injury treated nonoperatively during the study period were included. The nonoperative treatment failed in only one patient (5.5%) who had refractory abdominal pain. However, no missed injuries and/or worsening of bleeding were observed during the operation. None of the patients died nor need angioembolization. No complications directly related to the liver were observed. Unrelated complications to the liver occurred in three patients (16.7%); one patient developed a tracheal stenosis (secondary to tracheal intubation); one had pleural effusion; and one developed an abscess in the pleural cavity. The hospital length of stay was on average 11.56 days. Conclusions In our experience, nonoperative management of grade IV liver injury for stable blunt trauma patients is associated with high success rates without significant complications.

Thirty post-menopausal women with breast abscess were treated at Port of Spain General Hospital, Trinidad, between 1976 and 1980. In this age group, breast abscess can be confused with cancer due to a lack of inflammatory features. History and physical examination are often not helpful in differentiating an abscess from carcinoma. Although the usual treatment of an abscess is incision and drainage, in post-menopausal women, excision of the lesion is helpful for accurate histological diagnosis. PMID:3628144

Because of the rise in community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), presentations to the emergency department for the evaluation of cutaneous abscesses have risen dramatically over the past 2 decades. Soft tissue point of care ultrasound (POCUS) differentiates abscess from cellulitis, determines the size and shape, and characterizes the contents of the abscess. It has been shown to improve medical decision-making and therefore the emergency management of cutaneous abscesses over physical examination alone. We report a case of an unusual nonhealing abscess in an 18-year-old woman with a recent history of foreign travel where soft tissue POCUS identified motion within the abscess pocket. This changed the management of the case, leading to the diagnosis of bot fly myiasis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Clinicians should entertain a broader differential for an apparent abscess and consider liberal use of soft tissue POCUS in these cases.

Emergency department visits for skin and soft tissue infections are increasing with the discovery of community-acquired methicillin-resistant Staphylococcus aureus. Whether abscesses treated surgically also require antibiotics is controversial. There are no published pediatric randomized controlled trials evaluating the need for antibiotics in skin abscess management. We determine the benefits of antibiotics in surgically managed pediatric skin abscesses. This was a double-blind, randomized, controlled trial. Pediatric patients were randomized to receive 10 days of placebo or trimethoprim-sulfamethoxazole after incision and draining. Follow-up consisted of a visit/call at 10 to 14 days and a call at 90 days. Primary outcome was treatment failure at the 10-day follow-up. Secondary outcome was new lesion development at the 10- and 90-day follow-ups. Noninferiority of placebo relative to trimethoprim-sulfamethoxazole for primary and secondary outcomes was assessed. One hundred sixty-one patients were enrolled, with 12 lost to follow-up. The failure rates were 5.3% (n=4/76) and 4.1% (n=3/73) in the placebo and antibiotic groups, respectively, yielding a difference of 1.2%, with a 1-sided 95% confidence interval (CI) (-infinity to 6.8%). Noninferiority was established with an equivalence threshold of 7%. New lesions occurred at the 10-day follow-up: 19 on placebo (26.4%) and 9 on antibiotics (12.9%), yielding a difference of 13.5%, with 95% 1-sided CI (-infinity to 24.3%). At the 3-month follow-up, 15 of 52 (28.8%) in the placebo group and 13 of 46 (28.3%) in the antibiotic group developed new lesions. The difference was 0.5%, with 95% 1-sided CI (-infinity to 15.6%). Antibiotics are not required for pediatric skin abscess resolution. Antibiotics may help prevent new lesions in the short term, but further studies are required.

Breast abscess is usually caused by Staphylococcus aureus in pregnant or lactating females. Salmonella spp. is occasionally associated with abscess formation in various organs, but breast abscess is a very rare complication. In enteric fever dissemination to multiple organ systems following bacteraemia can lead to localized abscess. We report a case of bilateral breast abscess due to Salmonella Typhi in an unmarried 35-year-old female without any predisposing conditions. She presented with fever and painful swelling of both the breasts. S. typhi was isolated from both breasts. Such rare cause must be suspected in females without any evident predisposing factors for effective management.

Mastitis and abscess in HIV-infected women increase the risk of breastfeeding transmission of HIV. Guidelines encourage women to stop breastfeeding on the affected breast and feed on the contralateral breast. However, impact of breast pathology on breast milk HIV dynamics is unknown. HIV RNA was quantified in 211 breast milk samples collected before, during, and after a clinical mastitis or an abscess diagnosis from 38 HIV-infected women participating in a Zambian breastfeeding study. HIV RNA quantity was compared between affected and unaffected breasts over time using generalized estimating equation models. A sample of 115 women without breast pathology was selected as a control group. In the affected breast, breast milk HIV RNA quantity increased from the pre- to during-pathology period by log(10) 0.45 copies per milliliter [95% confidence interval (CI): 0.16 to 0.74], and after symptom resolution, HIV RNA levels were no different from prepathology levels (log10 -0.04 copies per milliliter 95% CI: -0.33 to 0.25). In the contralateral, unaffected breast, HIV RNA quantity did not significantly increase (log(10) 0.15 copies per milliliter, 95% CI: -0.41 to 0.10). Increase was more marked in women with abscess or with a greater number of mastitis symptoms. HIV RNA was not significantly different between affected and unaffected women, except at the time of diagnosis. Breast milk HIV RNA increased modestly in the affected breast with unilateral mastitis or abscess and returned to prepathology levels with symptom resolution. Contralateral HIV RNA was not affected. Results support guidelines encouraging feeding from the contralateral breast to minimize the risk of HIV transmission associated with unilateral breast pathology.

This is the first report of breast abscess due to Salmonella enterica serotype Typhimurium. Staphylococcus aureus is known as the most common cause of breast abscess. Salmonella spp. may occasionally form localized abscesses after dissemination to various organ systems following a bacteraemia. But breast abscess related to Salmonella spp is a very rare complication. A 43-year-old female patient referred to our hospital with a lump, fever and mild pain in her breast. The patient was not pregnant or lactating at that time. She had a history of rheumatoid arthritis for 5 years and was under immunosuppressive therapy. Ultrasonography of the breast revealed an abscess. The abscess was drained and sent for culture to medical microbiology laboratory. The microorganism was identified as Salmonella enterica serotype Typhimurium and found to be sensitive to all antibiotics tested. The patient was cured after surgical debridement and antibiotic therapy. The abscess did not recur again. This case is presented to draw attention to non-typhoidal Salmonella as rare causes of breast abscess and submission of specimens to the microbiology laboratory for accurate diagnosis and treatment especially in patients with underlying immunosuppressive diseases.

His body temperature was 38.0 degrees C, and he had the disturbance of consciousness, tachypnea, tachycardia and hepatomegaly with tenderness. Laboratory findings showed highly inflammatory reactions, DIC and hepatorenal dysfunction. Abdominal CT and US revealed multiple liver abscess with portal vein thrombus. Serratia rubidaea was detected in the blood culture. SBT/CPZ and TOB were administered and he recovered. This is a rare case of Serratia rubidaea sepsis. It is also necessary to pay attention to Serratia infections as well as S. marcescens.

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.

We aim to compare the incision and drainage against ultrasound-guided aspiration for the treatment of breast abscesses. Sixty-four patients were randomly allocated to Group A (incision and drainage) and Group B (needle aspiration). Incision and drainage was done under general, whereas aspiration was done under local anesthesia with antibiotic coverage after the pus sample was taken for cultures. Time taken to resolve symptoms including point tenderness, erythema and hyperthermia, recurrence of breast abscess, and healing time was recorded. Patients were followed until 8 weeks. Culture and sensitivity of the pus were done. Data were analyzed in SPSS 16.0. The mean difference of healing time was significant (P = 0.001). A total of 93.3 per cent were healed in Group B and 76.6 per cent in Group A (P = 0.033). Twenty-two samples (34.37%) had no bacterial yield and the remaining 42 samples (65.6%) yielded 11 anaerobic cultures (17.18%) and 31 aerobic cultures (48.4%). Ultrasound-guided aspiration of breast abscesses with the judicious use of antibiotics is a better treatment modality than incision and drainage.

Sixty-seven patients with brain abscess were managed over 19 years (1975-1993). Our series had a 2.5 to 1 male predominance; the age distribution was from 3 days to 81 years. The underlying conditions of hematogenic brain abscesses (n = 33; 49%) included lung infections (n = 16), heart disease (n = 4), sepsis (n = 10), and other foci (n = 3). Otolaryngologic infections led to the abscess in 10 cases; there were 9 traumatic abscesses. The causes remained unknown in 15 cases. There were 47 solitary abscesses (70%) and 20 multiple abscesses. The most frequent presenting signs and symptoms were neurologic deficits (n = 17), disturbances of consciousness (n = 14), seizures (n = 6), and headaches, meningism and vomiting (n = 13). Causative organisms were isolated in 39 cases (58%) and included staphylococci (n = 6), streptococci (n = 6), enterobacteriae (n = 2), and anaerobic pathogens (n = 9). The most reliable laboratory sign of inflammation was an elevated ESR (52/59 patients). With the advent of computed tomography, burr hole aspiration of the abscess with or without drainage was possible in 30 cases; the mortality in this subgroup was 9%. All 4 patients with surgical excision in the pre CT-era died. The mortality of patients treated with antibiotics only was 62% (18/29). Overall mortality was 37% (25/67), including 5 cases with post mortem-diagnosis of brain abscess. Good recovery was achieved in 29/42 survivors. Predictors of a poor outcome were the patient's age, the level of consciousness, multiple abscesses, polybacterial cultures, and a hematogenic etiology, but not the size of the abscess.

To investigate predictive factors of surgical management of subperiosteal orbital abscess in children. A retrospective monocentric study was conducted between 2000 and 2011 with children hospitalized for acute pediatric orbital cellulitis (APOC). Clinical, biological and radiological data as well as medical and surgical management were collected and analyzed. All patients received intravenous antibiotics and underwent a CT-scan. Orbit and subperiosteal intraorbital abscess dimensions were measured on axial and coronal planes and the abscess volume was calculated using a spheroid model. Eighty-three children with APOC (mean age: 4.5 years) were included, 53 were boys (63.9%). Thirty-two children (38.6%) presented with a subperiosteal orbital abscess. Mean abscess volume was 570mm(3) and mean exophthalmos was 4.7mm. Twenty patients were treated surgically, 11 of which by an endoscopic approach. A positive correlation was observed between the volume of the abscess or exophthalmos and surgical drainage: 57.9% of patients underwent surgery when exophthalmos was >4mm, 29.4% between 2 and 4mm, and none when <2mm. All patients with an abscess volume >500mm(3) or >5% of orbital volume were operated on whereas only 30% or 39% of patients, respectively, in case of smaller volumes (P<0.05). Surgery for subperiosteal orbital abscess is usually performed in case of visual complications or unfavorable medical outcome. The importance of the exophthalmos and the volume of the abscess measured on the CT-scan are predictive factors of surgery in children with subperiosteal orbital abscess without visual complications.

Background We investigated the patients and microbiological risk factors that predispose to the development of primary breast abscesses and subsequent recurrence. Methods Patients with a primary breast abscess requiring surgical therapy between January 1, 2000 and December 31, 2006 were reviewed. Recurrent breast abscess was defined by the need for repeated drainage within 6 months. Patient characteristics were compared to the general population and between groups. Results A total of 89 patients with a primary breast abscess were identified; 12 (14%) were lactational and 77 (86%) were nonlactational. None of the lactational abscesses recurred, whereas 43 (57%) of the nonlactational abscesses did so (P < 0.01). Compared to the general population, patients with a primary breast abscess were predominantly African American (64% vs. 12%), had higher rates of obesity (body mass index > 30: 43% vs. 22%), and were tobacco smokers (45% vs, 23%) (P < 0.01 for all). The only factor significantly associated with recurrence in the multivariate logistic regression analysis was tobacco smoking (P = 0.003). Compared to patients who did not have a recurrence, patients with recurrent breast abscesses had a higher incidence of mixed bacteria (20.5% vs. 8.9%), anaerobes (4.5% vs. 0%), and Proteus (9.1% vs. 4.4%) but lower incidence of Staphylococcus (4.6% vs. 24.4%) (P < 0.05 for each). Conclusions Risk factors for developing a primary breast abscess include African American race, obesity, and tobacco smoking. Patients with recurrent breast abscesses are more likely to be smokers and have mixed bacterial and anaerobic infections. Broader antibiotic coverage should be considered for the higher risk groups.

Brucellosis is an endemic disease seen in many countries. It may affect different organ systems. Brucellar breast abscess is a rare entity. We report the radiological findings of breast abscess due to brucella. A 63-year-old female was investigated with mammography, ultrasonography, magnetic resonance imaging (MRI), and magnetic resonance spectroscopy (MRS). A mass measuring 25 x 20 x 15 mm was detected in the left breast on mammography and ultrasonography. The mass was homogenously hyperintense on T1- and T2-weighted MRI images. On contrast-enhanced T1-weighted images, peripheral capsular enhancement was found. MR spectroscopic analysis of the mass revealed elevated lipid and acetate peaks. The diagnosis was provided by fine needle aspiration biopsy and specimen culture. The lesion had diminished in size after 12 months' treatment with combined tetracycline and rifampicine.

Surgical vs ultrasound-guided drainage of deep neck space abscesses: a randomized controlled trial: surgical vs ultrasound drainage.

Deep neck space abscesses (DNAs) are relatively common otolaryngology-head and neck surgery emergencies and can result in significant morbidity with potential mortality. Traditionally, surgical incision and drainage (I&D) with antibiotics has been the mainstay of treatment. Some reports have suggested that ultrasound-guided drainage (USD) is a less invasive and effective alternative in select cases. To compare I&D vs USD of well-defined DNAs, using a randomized controlled clinical trial design. The primary outcome measure was effectiveness (length of hospital stay (LOHS) and safety), and the secondary outcome measure was overall cost to the healthcare system. Patients presenting to the University of Alberta Emergency Department with a well-defined deep neck space abscess were recruited in the study. Patients were randomized to surgical or US-guided drainage, placed on intravenous antibiotics and admitted with airway precautions. Following drainage with either intervention, abscess collections were cultured and drains were left in place until discharge. Seventeen patients were recruited in the study. We found a significant difference in mean LOHS between patients who underwent USD (3.1 days) vs I&D (5.2 days). We identified significant cost savings associated with USD with a 41% cost reduction in comparison to I&D. USD drainage of deep neck space abscesses in a certain patient population is effective, safe, and results in a significant cost savings to the healthcare system.

We have already reported the feasibility, safety, and excellent long-term results of distal pancreatectomy with en-bloc celiac axis resection (DP-CAR) for locally advanced pancreatic body cancer. An international standard for the surgical technique of DP-CAR has yet to be established. DP-CAR was carefully performed in 42 patients in Hokkaido University Hospital from 1998 to July 2007. Arterial blood flow alteration and collateral flow development toward the liver and stomach was obtained following preoperative routine transcatheter arterial embolization of the common hepatic artery. The right-sided approach to the superior mesenteric artery and celiac artery, and the preservation of the inferior pancreatoduodenal artery during the dissection of the plexus around the pancreatic head, are the key techniques in DP-CAR. The operative morbidity and mortality were 43 and 4.8%, respectively. R0 resection could be done in 39 (93%) patients. Median operation time and intraoperative blood loss were 478 min and 1030 ml, respectively. Ischemic gastropathy was complicated in 5 (12%) patients, but liver abscess was found in only one patient and no liver failure was encountered. We emphasize again the feasibility and safety of DP-CAR; it should be a treatment of choice for locally advanced pancreatic body cancer.

We report a case of splenic abscess with multiple brain abscesses caused by Streptococcus intermedius in a healthy young man without any identifiable risk factors, which resolved with percutaneous drainage and antibiotics. Streptococcus intermedius, a member of the Streptococcus anginosus group, is a common commensal organism of the oral cavity and gastrointestinal tract, and it is a known cause of deep-seated infections. Suppurative infections caused by Streptococcus anginosus group are sometimes associated with bacteremia, but hematogenous spread of infection from an occult source leading to concurrent splenic abscess and multiple brain abscesses has never been previously reported in a healthy young individual.

To analyze cases with posttraumatic lenticular abscess and study the etiology, clinical presentation, management, and outcome. Retrospective case series. Seventeen eyes of 17 patients with traumatic lenticular abscesses were managed with extracapsular cataract extraction after aspirating the abscess. The mean age of the patients was 40.3 years, and males constituted 82%. The mean time to presentation after injury was 14.35 days (range, one to 60 days), and the patients had a mean follow-up of 125.94 days (range, 21 to 300 days). Culture of the lenticular abscess revealed bacterial growth in eight cases (47%) and fungi in four cases (23.5%). In five (29.4%) cases, culture was negative. Staphylococcus epidermidis grew in seven cases (41%). Thirteen eyes (77%) had best-corrected visual acuity better than 20/120. Surgical removal of the abscess, with systemic and local antimicrobial treatment is effective in cases of posttraumatic intralenticular abscess.

Retropharyngeal abscess with mediastinal extension in an infant--still existing?

PubMed

Bakshi, Rijuneeta; Grover, Gogia

2009-03-01

The objective of the present case report was to note that despite the low incidence of retropharyngeal abscess in the present antibiotic era, children, especially infants, can develop this condition. If early diagnosis is missed, the abscess may extend into the mediastinum and can be life threatening. Case reports of mediastinal abscess in the past literature along with the current case. The present case was successfully managed by surgical drainage of the abscess via transcervical route along with intravenous antibiotic therapy, and the recovery was uneventful. Although the incidence of retropharyngeal abscess has declined with the widespread use of antibiotics, the presenting symptom can be overlooked in a pediatric population, especially infants, and can extend along the fascial planes to the mediastinum when the recovery becomes difficult. The present report is an effort to draw attention to this life-threatening complication of retropharyngeal abscess, emphasize the role of early diagnosis, and prompt surgical management.

Objective: To explore the relationship between genotype and phenotype of ABCB11 deficiency. Methods: Clinical data of two siblings with ABCB11 deficiency were retrospectively analyzed. Related literature from PubMed, CNKI and Wangfang databases was reviewed to date (up to August 2017) with 'ABCB11 gene' or 'bile salt export pump', 'cholestasis' and 'child' as key words. Results: The patients were siblings. Both of them presented as jaundice, pruritus and hepatosplenomegaly since 3 days after birth. Significant laboratory findings on admission of the older sister included high total bilirubin, 170 µmol/L;conjugated bilirubin, 115.8 µmol/L;alanine aminotransferase, 168 U/L;total bile acid 186.3 µmol/L and normal gamma-glutamyl transpeptidase. While routine laboratory data of the younger brother were as follows: total bilirubin, 148.8 µmol/L;conjugated bilirubin, 96.3 µmol/L;alanine aminotransferase, 232.8 U/L;total bile acid 226 µmol/L, and normal gamma-glutamyl transpeptidase.Both received ursodeoxycholic acid and fat-soluble vitamins. Liver pathology of the younger brother showed giant hepatocytes with ballooning degeneration, focal necrosis and intrahepatic cholestasis. Both the patients harbor the same compound heterozygous mutations in ABCB11 gene, c.145C>T (p.Q49X) and c.1510G>A (p.E504K). The sister is 9 years old now, with normal liver function. Jaundice faded around 3 months after birth, pruritus relieved at age 5, and medications was stopped since then. The brother progressed to liver failure after an operation on perianal abscess when he was 8-month-old, and received living-related liver transplantation when he was 9 month and 20 days old (from his mother). Now he is 1 year and 5 months old, with normal liver function. Both are under our follow-up. Literature review revealed 18 ABCB11 deficiency patients from 7 families who had apparent different prognoses, within each family the siblings had the same ABCB11 gene mutation. Seven cases relieved after ursodeoxycholic acid therapy and/or partial external biliary diversion, 5 received orthotopic liver transplantation, 2 developed hepatocellular carcinoma and 4 cases died in childhood. Conclusions: The clinical manifestations of ABCB11 deficiency may vary greatly in patients carrying the same genotype, even in siblings. Patients should be managed in individualized maner.

We and others have shown previously that over-expression of hepcidin antimicrobial peptide, independently of inflammation, induces several features of anemia of inflammation and chronic disease, including hypoferremia, sequestration of iron stores and iron-restricted erythropoiesis. Because the iron-restricted erythropoiesis evident in hepcidin transgenic mice differs from the normocytic, normochromic anemia most often observed in anemia of inflammation, we tested the hypothesis that chronic inflammation may contribute additional features to anemia of inflammation which continue to impair erythropoiesis following the acute phase of inflammation in which hepcidin is active. We compared erythropoiesis and iron handling in mice with turpentine-induced sterile abscesses with erythropoiesis and iron handling in hepcidin transgenic mice. We compared erythrocyte indices, expression of genes in the hepcidin regulatory pathway, tissue iron distribution, expression of heme and iron transport genes in splenic macrophages, the phenotype of erythroid maturation and chloromethyl dichlorodihydrofluorescein diacetate, acetyl ester fluorescence. Mice with sterile abscesses exhibited an intense, acute inflammatory phase followed by a mild to moderate chronic inflammatory phase. We found that erythrocytes in mice with sterile abscesses were normocytic and normochromic in contrast to those in hepcidin transgenic mice. We also observed that although hypoferremia resolved in the late phases of inflammation, erythropoiesis remained suppressed, with evidence of inefficient maturation of erythroid precursors in the bone marrow of mice with sterile abscesses. Finally, we observed increased oxidative stress in erythroid progenitors and circulating erythrocytes of mice with sterile abscesses which was not evident in hepcidin transgenic mice. Our results suggest that chronic inflammation inhibits late stages of erythroid production in the turpentine-induced sterile abscess model and induces features of impaired erythropoiesis which are distinct from those in hepcidin transgenic mice.

Brain abscess is an unusual complication of uncontrolled diabetes. A solitary thalamic abscess is an uncommon type of brain abscess. We report a case of thalamic abscess, whereupon diabetes mellitus and periodontitis were diagnosed. The diagnosis and management of thalamic abscess, and the interplay of type 2 diabetes and periodontitis are discussed. A 56-year-old, Caucasian, man with no medical or travel history, presented with 5-day symptoms of meningeal irritation. Body mass index 30.6 kg/m2. CT demonstrated a solitary midline lesion with neoplasia as a differential diagnosis. It was biopsied and cultures grew Streptococcus milleri. He was treated by stereotactic puncture, external drainage and targeted intrathecal and systemic antibiotic therapy. HIV negative but glycated haemoglobin (HbA1c) 10.7% (93 mmol/mol). Dental examination revealed a small molar abscess. Radiological resolution of the thalamic abscess occurred within 2 months. Diabetes improved with 7 weeks of insulin, and maintained on metformin, HbA1c 6.9% (51 mmol/mol). There was no residual neurological disability. PMID:25053670

Mediastinal abscess is a fatal condition, treatment of mediastinal abscess is with antibiotics and sometimes surgery for debridement and drainage. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a safe assessment and candidate treatment method of mediastinal lesions. This study aimed to HYPERLINK "javascript:void(0);" discuss risks and benefits in treatment of mediastinal abscess by EBUS-TBNA. We noticed a 56-year-old man with developed bilateral pneumonia and sepsis after puncture of mediastinal abscess by EBUS-TBNA. The patient was successfully treated with a combination of systemic anti-infection treatment and intracavitary administration of antibiotics, antifungal and repeated drainage and lavage via EBUS-TBNA, in 1 year follow-up without recurrence. This study indicated infection spread risk of mediastinal abscess after EBUS-TBNA, and mediastinal abscess was successfully cured by combination of systemic anti-infection and local intervention through EBUS-TBNA. EBUS-TBNA is a potential effective minimally invasive treatment for mediastinal abscess, and it is necessary to be aware of clinical complications after puncture of mediastinal infectious lesions by EBUS-TBNA. © 2015 John Wiley & Sons Ltd.

BACKGROUND AND AIM: Preauricular sinus abscess is a common congenital external ear disease. This abscess is usually misdiagnosed because it is commonly overlooked during physical examination. In Nigeria, the prevalence was 9.3% in Ilorin, north central Nigeria This study is to determine the distribution and clinical presentation of the preauricular sinus abscess in Ekiti, south west Nigeria. MATERIALS AND METHODS: This is a prospective hospital based study of all patients with diagnosis of preauricular sinus abscess seen in our clinic carried out between April 2008 to March 2010. Detailed clinical history, administered interviewer’s assisted questionnaires full examination and. Data obtained were collated and analysed. RESULTS: Preauricular sinus were noticed in 184 (4.4%) out of 4170 patients seen during the study period. Preauricular sinus abscess were noticed in 21 (11.4%) of the preauricular sinuses especially in children. Unilateral preauricular sinus abscess accounted for 90.5%. Common presenting complaints were preauricular swelling (81.0%), 90.5% with recurrent earaches, 76.2% with ear discharges. All patients had antibiotic / analgesic while 17 out of 21 (81.0%) had surgical excisions. CONCLUSION: Preauricular sinus abscess were noticed among 11.4% of the preauricular sinuses especially in children, unilateral preauricular sinus abscess accounted for 90.5%. Common complaints were otorrhoea, earaches, and swelling and they were mostly managed surgically. PMID:24711764

A significant number of people suffer iatrogenic bile duct injury during laparoscopic cholescystectomy. Biliary-digestive bypass may be complicated by stenosis and biliary sepsis, affecting both quality of life and life expectancy. To avoid bypass synthetic grafts have been used, which are expensive. Evaluating autologous implantation of peritoneus as alternative of bile duct repair. Under general anesthesia, ten New Zealand adult rabbits were operated, common bile duct approached and sectioned underneath the cystic duct followed by a liver biopsy. An autologous graft was built of peritoneum and graft-bile duct proximal and distal end-to-end anastomosis done. Animals were followed-up by weekly bilirrubin and transferases. Rabbits were scheduled euthanized and a liver biopsy done for histological examinations. Autologous graft was easy to create and all rabbits survived. They did not develop jaundice or alterations in their normal habits. At necropsy, autologous grafts were removed and no signs of occlusion were noticed. Moderate short-term liver damage was observed but long-term damage was negligible. Bileoma and pyogenic liver abscess were observed in two animals, respectively. Our results favourably match well-known procedures used for bile duct repair, especially in cases of severe injury (Bismuth-Strasberg E1-3): it seems less complicated than biliary-digestive bypass, not as expensive as synthetic grafts, and much easier to build than human amnion graft. Interposing an autologous graft of peritoneum is an easy-to-create surgical procedure and circumferential bile duct injuries were adequately repaired.

Pyogenic brain abscess, a 15 year survey

PubMed Central

2012-01-01

Background Brain abscess is a potentially fatal disease. This study assesses clinical aspects of brain abscess in a large hospital cohort. Methods Retrospective review of adult patients with pyogenic brain abscess at Rigshospitalet University Hospital, Denmark between 1994 and 2009. Prognostic factors associated with Glasgow Outcome Score (GOS) (death, severe disability or vegetative state) were assessed by logistic regression. Results 102 patients were included. On admission, only 20% of patients had a triad of fever, headache and nausea, 39% had no fever, 26% had normal CRP and 49% had no leucocytosis. Median delay from symptom onset to antibiotic treatment was 7 days (range 0–97 days). Source of infection was contiguous in 36%, haematogenous in 28%, surgical or traumatic in 9% and unknown in 27% of cases. Abscess location did not accurately predict the portal of entry. 67% were treated by burr hole aspiration, 20% by craniotomy and 13% by antibiotics alone. Median duration of antibiotic treatment was 62 days. No cases of recurrent abscess were observed. At discharge 23% had GOS ≤3. The 1-, 3- and 12-month mortality was 11%, 17% and 19%. Adverse outcome was associated with a low GCS at admission, presence of comorbidities and intraventricular rupture of abscess. Conclusions The clinical signs of brain abscess are unspecific, many patients presented without clear signs of infection and diagnosis and treatment were often delayed. Decreased GCS, presence of comorbidities and intraventricular rupture of brain abscess were associated with poor outcome. Brain abscess remains associated with considerable morbidity and mortality.

Intra-abdominal abscess is a common complication of Crohn disease in children. Prior studies, primarily in adults, have shown that percutaneous abscess drainage is a safe and effective treatment for this condition; however, the data regarding this procedure and indications in pediatric patients is limited. Our aim was to determine the success rate of percutaneous abscess drainage for abscesses related to Crohn disease in pediatric patients with a focus on treatment endpoints that are relevant in the era of biological medical therapy. We retrospectively reviewed 25 cases of patients ages ≤20 years with Crohn disease who underwent percutaneous abscess drainage. Technical success was defined as catheter placement within the abscess with reduction in abscess size on post-treatment imaging. Clinical success was defined as (1) no surgery within 1 year of drainage or (2) surgical resection following drainage with no residual abscess at surgery or on preoperative imaging. Multiple clinical parameters were analyzed for association with treatment success or failure. All cases were classified as technical successes. Nineteen cases were classified as clinical successes (76%), including 7 patients (28%) who required no surgery within 1 year of percutaneous drainage and 12 patients (48%) who had elective bowel resection within 1 year. There was a statistically significant association between resumption of immunosuppressive therapy within 8 weeks of drainage and both clinical success (P < 0.01) and avoidance of surgery after 1 year (P < 0.01). Percutaneous abscess drainage is an effective treatment for Crohn disease-related abscesses in pediatric patients. Early resumption of immunosuppressive therapy is statistically associated with both clinical success and avoidance of bowel resection, suggesting a role for percutaneous drainage in facilitating prompt initiation of medical therapy and preventing surgical bowel resection.

The goal of this retrospective work was to study the clinical aspects and the principles of management of the abscess of the breast in order to determine a convenient and recent therapeutic attitude. Our retrospective survey concerns 114 cases of breast abscess collected in a surgery department over a period of 14 years, from 1990 to 2003. All patients have been operated and the diagnosis confirmed through the operation. The puerperal abscesses have been noted in 31 cases. One hundred and four women and ten men were concerned, with a sex-ratio of 0.1. The medium age was 33 years old for the women and 42 years for the men. The diagnosis was based on the clinical criteria, confirmed by the ultrasonography in 11 cases out of 16 and by the mammary puncture in 15 cases out of 22. Two non-puerperal abscesses have revealed an infiltrating canal carcinoma. The Staphylococcus aureus was the germ the most frequently met, concerning 8 cases out of 16. The surgical biopsies carried out in 52 cases revealed a fibrocystic mastopathy in six cases, a canalar ectasia in two cases and an infiltrating canalar carcinoma in two cases. The surgical treatment, performed in any case, was associated to an anti-staphylococcus antibiotherapy. The recurrence of the abscess has been observed in four cases. The frequency of pyogenic abscess of the breast, particularly the puerperal abscesses, has considerably decreased. The non-puerperal abscesses often pose a differential diagnosis problem with the very aggressive inflammatory cancers. The percutaneous ultrasonography guided drainage must be proposed in first intention to treat the abscesses of the breast. However, surgical treatment is still valid with an abscess either relapsing or chronic, or else the failure of the non-operative processes.

Brain abscesses carries a high morbidity and mortality, and despite medical advances, it continues to pose diagnostic and therapeutic challenges worldwide. The traditional surgical approaches to treating brain abscess (burr hole aspiration and craniotomy) have both advantages and disadvantages and remain controversial. Here we report a single institution's experience with a new surgical approach for brain abscess. We retrospectively analyzed 46 patients with intracranial abscess who underwent continuous irrigation and drainage through a double-cavity sleeve tube placed surgically in conjunction with a 4-week course of intravenous cefotaxime and metronidazole at Renmin Hospital of Wuhan University between January 2008 and December 2016. The patients' medical records were analyzed for demographic data, clinical presentation, predisposing factors, imaging findings, microbiological test results, treatments, surgical techniques, and outcomes. The 46 patients included 29 males and 17 females, ranging in age from 22 to 74 years. A single abscess was detected in 34 patients, whereas 12 patients had multiple abscesses. The average duration of hospitalization was 12.6 days. After treatment, 38 of the 46 patients resumed a normal life despite minor deficits (Glasgow Outcome Score [GOS] 5), 6 patients exhibited slight neurologic deficits (GOS 4), and 2 patients died of severe systemic infection and multiorgan failure. In particular, a patient with a brain abscess broken into the ventricle recovered well (GOS 5). No patient required repeat aspiration or surgical excision. Continuous brain abscess cavity irrigation and drainage with a double-cavity sleeve tube is an effective treatment for brain abscess and produces excellent results, especially for an abscess broken into the ventricle. It combines the advantages of burr hole aspiration and open craniotomy excision. It is easy to perform and reduces costs and damage to the patient, and also shortens hospitalization time and antibiotic treatment time, greatly reducing the likelihood of reoperation. This approach may be the optimal choice to treat brain abscess. Copyright © 2017. Published by Elsevier Inc.

An Entamoeba sp. strain, P19-061405, was isolated from a rhesus monkey in Nepal and characterized genetically. The strain was initially identified as Entamoeba histolytica using PCR amplification of peroxiredoxin genes. However, sequence analysis of the 18S rRNA gene showed a 0.8% difference when compared to the reference E. histolytica HM-1:IMSS human strain. Differences were also observed in the 5.8S rRNA gene and the internal transcribed spacer (ITS) regions 1 and 2, and analysis of the serine-rich protein gene from the monkey strain showed unique codon usages compared to E. histolytica isolated from humans. The amino acid sequences of two hexokinases and two glucose phosphate isomerases also differed from those of E. histolytica. Isoenzyme analyses of these enzymes in the monkey strain showed different electrophoretic mobility patterns compared with E. histolytica isolates. Analysis of peroxiredoxin genes indicated the presence of at least seven different types of protein, none of which were identical to proteins in E. histolytica. When the trophozoites from the monkey strain were inoculated into the livers of hamsters, formation of amebic abscesses was observed 7 days after the injection. These results demonstrate that the strain is genetically different from E. histolytica and is virulent. Revival of the name Entamoeba nuttalli is proposed for the organism.

CLEC4F Is an Inducible C-Type Lectin in F4/80-Positive Cells and Is Involved in Alpha-Galactosylceramide Presentation in Liver

CLEC4F, a member of C-type lectin, was first purified from rat liver extract with high binding affinity to fucose, galactose (Gal), N-acetylgalactosamine (GalNAc), and un-sialylated glucosphingolipids with GalNAc or Gal terminus. However, the biological functions of CLEC4F have not been elucidated. To address this question, we examined the expression and distribution of murine CLEC4F, determined its binding specificity by glycan array, and investigated its function using CLEC4F knockout (Clec4f−/−) mice. We found that CLEC4F is a heavily glycosylated membrane protein co-expressed with F4/80 on Kupffer cells. In contrast to F4/80, CLEC4F is detectable in fetal livers at embryonic day 11.5 (E11.5) but not in yolk sac, suggesting the expression of CLEC4F is induced as cells migrate from yolk cells to the liver. Even though CLEC4F is not detectable in tissues outside liver, both residential Kupffer cells and infiltrating mononuclear cells surrounding liver abscesses are CLEC4F-positive upon Listeria monocytogenes (L. monocytogenes) infection. While CLEC4F has strong binding to Gal and GalNAc, terminal fucosylation inhibits CLEC4F recognition to several glycans such as Fucosyl GM1, Globo H, Bb3∼4 and other fucosyl-glycans. Moreover, CLEC4F interacts with alpha-galactosylceramide (α-GalCer) in a calcium-dependent manner and participates in the presentation of α-GalCer to natural killer T (NKT) cells. This suggests that CLEC4F is a C-type lectin with diverse binding specificity expressed on residential Kupffer cells and infiltrating monocytes in the liver, and may play an important role to modulate glycolipids presentation on Kupffer cells.

Pyrogenic liver abscesses (PLA) can be caused by cholangitis associated with hepatolithiasis and cholangitis related to an abnormal bilioenteric communication, such as a hepaticojejunostomy or the presence of indwelling biliary stents. Our aim was to evaluate the clinical characteristics of PLA of biliary origin. We compared patients with PLA related to biliary tract disease (PLA-B; n = 125) with patients with PLA not related to biliary tract disease (PLA-NB; n = 444). We also separated the patients with PLA-B into PLA related to biliary tract disease that involved an abnormal bilioenteric communication, including hepaticojejunostomy and indwelling biliary stents (PLA-B-AC; n = 38), and PLA-B not related to abnormal communication (n = 87), and compared them. Among the 569 patients with PLA from 2008 to 2013, the most common etiologies were cryptogenic (n = 341; 60%) and biliary (n = 125; 22%). Patients with PLA-B tended to have a higher maximum body temperature and a greater leukocytosis. The incidences of bacteremia, septic shock, death, and postdischarge recurrence were greater in the PLA-B group when compared with the PLA-NB group. The most commonly isolated pathogenic bacteria in PLA-B group were Escherichia coli (36%) and Klebsiella pneumonia (23%). In contrast, in the PLA-NB group, the most common pathogen was K pneumonia (64%), whereas E coli was uncommon (only 5%). Independent risk factors for the occurrence of PLA-B were isolates with multidrug resistant (MDR) bacteria, bacteremia, E coli, and polymicrobial infection. In the group of PLA-B-AC, risk factors included MDR bacteria and a history of malignancy. The occurrences of PLA-B are often infected with MDR bacteria and mixed infections caused mainly by E coli and other isolates and associated with bacteremia; PLA-B-AC are associated with MDR bacteria and a history of malignancy.

To evaluate safety in an interim analysis of transarterial chemoembolization (TACE) with doxorubicin-eluting beads (DEB) in 13 patients with hepatic metastases from neuroendocrine tumors (NETs) as part of a phase II trial. Institutional Review Board approval and informed consent were obtained. Thirteen patients completed preliminary safety analysis. Their mean age was 65 years, Eastern Cooperative Oncology Group status was 0/1, tumor burden range was 4-75 %, and mean targeted tumor size was 5.9 cm. Up to four DEB-TACE sessions (100-300 {mu}m beads loaded with {<=}100 mg doxorubicin) within 6 months were allowed. Tumor response was assessed by magnetic resonance imagingmore » 1 month after treatment using contrast-enhancement [European Association for the Study of the Liver (EASL) and size Response Evaluation Criteria in Solid Tumors (RECIST)] criteria. Safety was assessed by National Cancer Institute Common Terminology Criteria. DEB-TACE was successfully performed in all 13 patients. At 1 month follow-up, there was a mean 12 % decrease in tumor size (p < 0.0003) and a 56 % decrease in tumor enhancement (p < 0.0001). By EASL criteria, the targeted lesion objective response rate was 78 %. Grade 3 to 4 toxicities were fatigue (23 %), increased alanine amino transferase (15 %), hyperglycemia (15 %), and abdominal pain (8 %). Seven patients developed bilomas (54 %); all of these patients had multiple small (<4 cm) lesions. Subsequently, four underwent percutaneous drainage, three for abscess formation and one for symptoms related to mass effect. Although biloma and liver abscess are known risks after TACE, the high incidence in our study population was unexpected and forced interruption of the trial. Although this occurred in a small group of patients, we have changed our technique and patient selection as a result of these findings, thus allowing resumption of the trial.« less

A lung abscess is a circumscribed collection of pus in the lung as a result of a microbial infection, which leads to cavity formation and often a radiographic finding of an air fluid level. Patients with lung abscesses commonly present to their primary care physician or to the emergency department with "nonresolving pneumonia." Although, the incidence of lung abscess has declined since the introduction of antibiotic treatment, it still carries a mortality of up to 10%-20%. This article discusses in detail the up-to-date microbiology and the management of lung abscesses.

We report a case of prostatic abscess in a 22-year-old man with metastatic testicular cancer being treated by BEP (bleomycin, etoposide and cisplatin) chemotherapy. This abscess was successfully treated by surgical drainage with transurethral resection of the prostate (TURP) under the guidance of transrectal ultrasound, allowing the patient to continue be receiving BEP without significant interruption. Drainage TURP is suggested to be a useful strategy for prostate abscess, when prompt control of symptoms caused by prostatic abscess is required.

A captive Malayan tapir was observed to have inappetence, weight loss, signs of depression, mild dehydration and diarrhoea. Haematological and serum biochemical tests showed anaemia, hypoproteinaemia, hyperfibrinogenaemia and neutrophilia with a left shift. Ultrasonic examination of the abdomen under anaesthesia revealed a well-encapsulated abscess. The abscess was marsupialised to the ventral body wall. Culture of the pus produced a mixed bacterial growth. Antimicrobial therapy was based on bacterial sensitivity results. Follow-up ultrasonic examinations showed resolution of the abscess. Ninety-one days after surgery the tapir began regurgitating food and water. An abscess originating from the stomach and occluding the lumen of the duodenum was identified at surgery. The abscess ruptured during surgical manipulations and the tapir was euthanased.

Harold Neuhof was one of the pioneers of thoracic surgery in the early decades of the last century. Inspired by his preceptor Howard Lilienthal he proposed an entirely new concept for surgery on acute lung abscess. The aim of his one-stage procedure was adequate drainage of the abscess cavity. His approach proved to be the first major breakthrough in the treatment of acute lung abscess. Therapy of pulmonary abscess was again radically changed by the advent of antibiotics in the late 1940s. However, the basic principles of Neuhof's concept still influence modern-day management of putrid lung abscess. Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc.

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. 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). 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). 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 identified in endodontic abscesses between the demographic region in Portland, Oregon and other regions.

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.

We reviewed the pathogenesis, clinical presentation, treatment options and outcomes of prostatic abscess in the post-antibiotic era, focusing on how patient risk factors and the emergence of multidrug-resistant organisms influence management of the condition. A MEDLINE search for "prostate abscess" or "prostatic abscess" was carried out. Prostate abscess is no longer considered a consequence of untreated urinary infection; now, men with prostatic abscess are typically debilitated or immunologically compromised, with >50% of patients having diabetes. In younger men, prostatic abscess can be the initial presentation of such chronic conditions. In older men, prostatic abscess is increasingly a complication of benign prostatic hyperplasia or prostate biopsy. Diagnosis is based on a physical examination, leukocytosis, leukocyturia and transrectal ultrasound, with magnetic resonance imaging serving as the preferred confirmatory imaging modality. Treatment of prostatic abscess is changing as a result of the emergence of atypical and drug-resistant organisms, such as extended-spectrum β-lactamase-producing enterobacteriaceae and methicillin-resistant Staphylococcus aureus. As many as 75% of infections are resistant to first-generation antibiotics, necessitating aggressive therapy with broad-spectrum parenteral antibiotics, such as third-generation cephalosporins, aztreonam or antibiotic combinations. A total of 80% of patients require early surgical drainage, frequently through a transurethral approach. In the post-antibiotic era, prostatic abscess is evolving from an uncommon complication of urinary infection to a consequence of immunodeficiency, growing antibiotic resistance and urological manipulation. This condition, primarily affecting patients with chronic medical conditions rendering them susceptible to atypical, drug-resistant organisms, requires prompt aggressive intervention with contemporary antibiotic therapy and surgical drainage. © 2017 The Japanese Urological Association.

Microbiology and Treatment of Acute Apical Abscesses

SUMMARY 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.

Brain abscesses result from a pyogenic parenchymal infection commonly initiated by Gram-positive bacteria such as Staphylococcus aureus. Although the host immune response elicited following infection is essential for effective bacterial containment, this response also contributes to the significant loss of brain parenchyma by necrosis that may be reduced by modulating the inflammatory response. Ciglitazone, a PPAR-γ agonist with anti-inflammatory properties, was evaluated for its ability to influence the course of brain abscess development when treatment was initiated 3 days following infection. Interestingly, abscess-associated bacterial burdens were significantly lower following ciglitazone administration, which could be explained, in part, by the finding that ciglitazone enhanced S. aureus phagocytosis by microglia. In addition, ciglitazone attenuated the expression of select inflammatory mediators during brain abscess development including inducible NO synthase, TNF-α, IL-1β, CXCL2, and CCL3. Unexpectedly, ciglitazone also accelerated brain abscess encapsulation, which was typified by the heightened expression of fibronectin and α-smooth muscle actin-positive myofibroblasts. Collectively, through its ability to attenuate excessive inflammation and accelerate abscess encapsulation, ciglitazone may effectively sequester brain abscesses and limit bacterial dissemination.

Periproctal inflammations related to the anus are characterized by the rapid spread of the infection to the surrounding tissue, which is determined by the anatomical characteristics and infectious agents. Inflammation, which starts as a phlegmon, quickly forms boundaries and an abscess develops in most cases. Up to 80-90% of anorectal abscesses develop according to the crypto-glandular theory on the basis of infection of the anal glands, spilling into the Morgagni crypts in the anal canal. Up to two-thirds of such abscesses are associated with the emergence of anorectal fistulas. Anorectal abscesses can be divided into marginal and subcutaneous perianal abscesses, submucosal, intersphincteric, ischiorectal and supralevator abscesses. Their diagnosis is based on thorough physical examination, sometimes also with the help of imaging methods such as computed tomography, magnetic resonance imaging and endoanal ultrasound. What is decisive for the successful treatment of anorectal abscessess is their early and adequate surgical drainage. Adjuvant antibiotic therapy is necessary only when the overall signs of sepsis are present and for patients with a comorbidity such as diabetes, valvular heart disease, or immunodeficiency.

We are reporting a rare case of de novo ovarian abscess in an endometrioma. Ovarian abscess within an endometrioma is a rare gynecological problem, but de novo abscess in the endometrioma is even rarer. Most of the ovarian abscesses develop in the endometriomas following interventions, e.g., aspiration, pelvic surgery, and oocyte retrieval. We are presenting a case of a spontaneous giant abscess in a large ovarian cyst in a nulliparous woman who presented with acute abdomen. Patient was treated in a district general hospital with multidisciplinary approach. Thirteen liters of the pus were drained. She has had a sub total (supra cervical) hysterectomy and bilateral salpingo-oophorectomy (BSO) performed. Histology of the abscess wall confirmed endometriotic nature of the cyst. Patient made an uneventful recovery and was discharged home on the 14th postoperative day. This case highlights that endometrioma and its complication can present as a surgical emergency and should be dealt as one. PMID:20589187

Although most breast abscesses can be treated with the current first-line treatment of antibiotics by needle aspiration, the therapeutic duration is lengthy and recurrences often occur. Therefore, we aimed to investigate the clinical efficacy of the Mammotome biopsy system (Johnson & Johnson Corp., New Brunswick, NJ) in a cohort of patients with breast abscesses. Forty lactating and 30 nonlactating breast abscess patients with unfavorable outcomes with antibiotic treatment and/or needle aspiration failure were recruited and treated with the Mammotome biopsy system. Skin inflammation of all patients disappeared within 6 days with no recurrence. The clinical outcomes in patients with an abscess size ≤ 3.5 cm was significantly better than those with an abscess size >3.5 cm (P = .025). The Mammotome biopsy system, an effective treatment strategy that is minimally invasive and less damaging, in combination with appropriate antibiotic therapy can be used safely as the first-line approach to breast abscess management.

A 63-year-old Japanese woman with a history of pemphigus was referred to us for abnormal findings of dynamic abdominal CT where three aneurysms of splenic artery and pancreaticoduodenal artery, celiac axis compression, and gall stone. Superior mesenteric artery supplied hepatic arterial flow via pancreaticoduodenal artery. Avoiding transarterial embolization to prompt arterial ischemia of liver/pancreas head/duodenum, she laparotomically underwent cholecystectomy, splenectomy, transection of median arcurate ligament, and ligation of splenic and inferior pancreaticoduodenal artery all at once. Postoperative course was uneventful except drainage of abdominal abscess, and she remained well without aneurysm recurring 40 months post. Important point of treatment for pancreaticoduodenal artery aneurysm associated with celiac artery occlusion/stenosis is both preventive solutions for rupture of aneurysm and hepatic/duodenal/pancreatic arterial ischemia. Remaining main arterial supply for the liver via pancreaticoduodenal artery from superior mesenteric artery would prompt recurrent aneurysm of pancreaticoduodenal artery. When a clinician encounters a case of pancreatic aneurysm associated with celiac axis occlusion, the case should be treated using with multimodality such as interventional radiology, and vascular surgery.

Breast abscess is a relatively important disease in the tropics, and yet this condition has received little attention in the literature. Breast abscess encourages artificial feeding, which in many instances may be responsible for gastroenteritis in infants. This occurs when foods are not properly prepared by mothers of low socioeconomic class with inadequate sanitation. Breast abscess occurs primarily in the lactating breast and is most commonly located in the upper half of the breast. The organism most commonly present in the pus is Staphylococcus aureus. When the abscess is localized, it may present with all the clinical features of a breast carcinoma. PMID:522185

Surgical vs ultrasound-guided drainage of deep neck space abscesses: a randomized controlled trial: surgical vs ultrasound drainage

PubMed Central

2013-01-01

Introduction Deep neck space abscesses (DNAs) are relatively common otolaryngology-head and neck surgery emergencies and can result in significant morbidity with potential mortality. Traditionally, surgical incision and drainage (I&D) with antibiotics has been the mainstay of treatment. Some reports have suggested that ultrasound-guided drainage (USD) is a less invasive and effective alternative in select cases. Objectives To compare I&D vs USD of well-defined DNAs, using a randomized controlled clinical trial design. The primary outcome measure was effectiveness (length of hospital stay (LOHS) and safety), and the secondary outcome measure was overall cost to the healthcare system. Methods Patients presenting to the University of Alberta Emergency Department with a well-defined deep neck space abscess were recruited in the study. Patients were randomized to surgical or US-guided drainage, placed on intravenous antibiotics and admitted with airway precautions. Following drainage with either intervention, abscess collections were cultured and drains were left in place until discharge. Results Seventeen patients were recruited in the study. We found a significant difference in mean LOHS between patients who underwent USD (3.1 days) vs I&D (5.2 days). We identified significant cost savings associated with USD with a 41% cost reduction in comparison to I&D. Conclusions USD drainage of deep neck space abscesses in a certain patient population is effective, safe, and results in a significant cost savings to the healthcare system. PMID:23672735

This study attempts to determine the antimicrobial resistance profiles of obligate anaerobic bacteria that were isolated from a periodontal abscess and to evaluate the prevalence of resistance genes in these bacteria. Forty-one periodontal abscess samples were cultivated on selective and non-selective culture media to isolate the oral anaerobes. Their antibiotic susceptibilities to clindamycin, doxycycline, amoxicillin, imipenem, cefradine, cefixime, roxithromycin, and metronidazole were determined using the agar dilution method, and polymerase chain reaction assays were performed to detect the presence of the ermF, tetQ, nim, and cfxA drug resistance genes. A total of 60 different bacterial colonies was isolated and identified. All of the isolates were sensitive to imipenem. Of the strains, 6.7%, 13.3%, 16.7%, and 25% were resistant to doxycycline, metronidazole, cefixime, and amoxicillin, respectively. The resistance rate for both clindamycin and roxithromycin was 31.7%. Approximately 60.7% of the strains had the ermF gene, and 53.3% of the amoxicillin-resistant strains were found to have the cfxA gene. Two nim genes that were found in eight metronidazole-resistant strains were identified as nimB. In the present study, the Prevotella species are the most frequently isolated obligate anaerobes from periodontal abscesses. The current results show their alarmingly high resistance rate against clindamycin and roxithromycin; thus, the use of these antibiotics is unacceptable for the empirical therapy of periodontal abscesses. A brief prevalence of four resistance genes in the anaerobic bacteria that were isolated was also demonstrated.

Hypervirulence and hypermucoviscosity: Two different but complementary Klebsiella spp. phenotypes?

PubMed Central

Catalán-Nájera, Juan Carlos; Garza-Ramos, Ulises; Barrios-Camacho, Humberto

2017-01-01

ABSTRACT Since the hypermucoviscous variants of Klebsiella pneumoniae were first reported, many cases of primary liver abscesses and other invasive infections caused by this pathogen have been described worldwide. Hypermucoviscosity is a phenotypic feature characterized by the formation of a viscous filament ≥5 mm when a bacterial colony is stretched by a bacteriological loop; this is the so-called positive string test. Hypermucoviscosity appears to be associated with this unusual and aggressive type of infection, and therefore, the causal strains are considered hypervirulent. Since these first reports, the terms hypermucoviscosity and hypervirulence have often been used synonymously. However, new evidence has suggested that hypermucoviscosity and hypervirulence are 2 different phenotypes that should not be used synonymously. Moreover, it is important to establish that a negative string test is insufficient in determining whether a strain is or is not hypervirulent. On the other hand, hypervirulence- and hypermucoviscosity-associated genes must be identified, considering that these phenotypes correspond to 2 different phenomena, regardless of whether they can act in synergy under certain circumstances. Therefore, it is essential to quickly identify the genetic determinants behind the hypervirulent phenotype to develop effective methodologies that can diagnose in a prompt and effective way these hypervirulent variants of K. pneumoniae.

The activity of a crude extract formulation was evaluated in experimental amoebic liver abscess in golden hamsters and in immunomodulation studies. The formulation comprises the following five plants-Boerhavia diffusa, Tinospora cordifolia, Berberis aristata, Terminalia chebula and Zingiber officinale. The formulation had a maximum cure rate of 73% at a dose of 800 mg/kg/day in hepatic amoebiasis reducing the average degree of infection (ADI) to 1.3 as compared to 4.2 for sham-treated controls. In immunomodulation studies humoral immunity was enhanced as evidenced by the haemagglutination titre. The T-cell counts remained unaffected in the animals treated with the formulation but cell-mediated immune response was stimulated as observed in the leukocyte migration inhibition (LMI) tests.

2017-10-01

To identify risk factors associated with the presence of methicillin-resistant Staphylococcus aureus (MRSA) in surgical cultures taken from incision and drainage (I&D) of head and neck abscesses in the pediatric population. Retrospective case series. All patients under 18 years of age with a head and neck abscess requiring I&D from 2009 to 2015 were reviewed. MRSA nasal swab cultures were taken from all patients upon hospitalization. Surgical cultures were obtained from all patients and correlated with MRSA nasal swab results. Univariate and multivariate logistic regression was performed, and odds ratios (ORs) along with descriptive statistics were analyzed. Of a total of 272 patients, there were 68 (25%) MRSA-positive abscesses. The majority (86.8%) of these abscesses were in children under 2 years of age. Overall, 12 (4.4%) presented with positive admission MRSA nasal swabs. Of these, 91.7% had MRSA-positive abscess cultures. Decreasing age in years showed an OR of 1.650 (P < 0.001) for MRSA-positive abscess, with children less than 1 year old having the highest OR of 10.74 (P < 0.001). Younger age and MRSA nasal colonization were two statistically significant risk factors for developing an MRSA abscess of the head and neck. This study demonstrates a high positive predictive value for MRSA-positive neck abscesses when nasal swab screenings were MRSA-positive (91.7%). Children under 2 years of age-especially those under 1 year of age-or those with MRSA nasal colonization can be considered a high-risk population that may benefit from empiric antibiotics against MRSA for head and neck abscesses. 4.

2018-01-01

Acute apical abscess is caused by bacteria that leave the infected dental root canal to invade the periodontal tissues. Most species occurring in abscesses are also found in asymptomatic infections; therefore, the possibility exists that not only the presence of certain species but also their specific counts influence the appearance of symptoms. This molecular study compared the frequency and levels of several candidate endodontic pathogens in teeth with acute apical abscesses and asymptomatic apical periodontitis. Samples were taken from the root canals of teeth with asymptomatic apical periodontitis (n = 73) and by aspiration of purulent exudate from acute abscesses (n = 55). DNA was extracted from samples and bacterial identifications were performed by a closed-ended semi-quantitative reverse-capture checkerboard approach targeting 40 bacterial species/phylotypes. Bacterial DNA was detected in all cases. In abscesses, the most prevalent taxa were Fusobacterium nucleatum (60%), Porphyromonas endodontalis (53%), Parvimonas micra (51%), and Streptococcus species (45%). The most frequently detected taxa in asymptomatic teeth were P. endodontalis (63%), Dialister invisus (58%), Olsenella uli (56%), and F. nucleatum (51%). None of the targeted taxa were significantly associated with abscesses when only mere presence was evaluated (p>0.05). However, semi-quantitative data demonstrated that P. endodontalis, Prevotella baroniae, Treponema denticola and Streptococcus species were significantly more frequent at levels >105 in abscesses than in asymptomatic cases (p<0.05). None of the target species/phylotypes were associated with abscesses in terms of frequency. However, some taxa were significantly found in higher levels in abscesses. Presence of a potentially virulent pathogen in high counts may increase the collective pathogenicity of the bacterial community and give rise to symptoms.

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 identified in endodontic abscesses between the demographic region in Portland, Oregon and other regions.

Crohn disease (CD) is a chronic inflammatory condition of the gastrointestinal tract that is complicated by fistulas, strictures, and intraabdominal abscesses (IAA) in 10%-30% of patients. To avoid surgical resection of the bowel, medical therapy with antibiotics (Ab) with or without percutaneous drainage (PD) is first undertaken. Our objectives are to examine the outcome of IAA in CD patients treated with antibiotics alone vs antibiotics and PD, and to identify risk factors for medical therapy failure. Charts for patient with CD who were diagnosed between 2004 and 2016 at the Women and Children's Hospital of Buffalo were retrospectively reviewed. We compared the two modalities of medical therapy (Ab + PD vs Ab alone) in terms of abscess resolution and the need for surgical intervention. Twenty-nine patients, ages ranging from 12 to 18years, mean 15.5±2.5, 48% Male with IAA were identified. Overall, 69% of abscesses failed medical therapy including 87% of the drained abscesses and 50% of nondrained abscesses, p=0.04. The abscesses that failed medical therapy were more likely to have been drained (P=0.03) as they were larger in size (P = 0.03), patients were more likely to have a known CD on immunosuppression (P=0.016), and more likely to have an associated upper GI disease (P=0.002), when compared to those that were successful with medical therapy alone. Our results show that the majority of our patients required surgical intervention for abscess treatment and resolution of associated findings despite drainage. Risk factors include big drainable abscesses, developing IAA while on immunosuppression, and a more extensive disease with associated fistulae and strictures. Small undrainable abscesses are likely to resolve with antibiotics alone, therefore early detection and treatment are essential. Level 2, retrospective study. Published by Elsevier Inc.

Optimal treatment of a brain abscess requires early clinical suspicion, and the diagnosis is usually made by identification of the abscess on contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI). The immediate first step is to reduce the potentially life-threatening brain mass (abscess and surrounding cerebral edema) and secure the diagnosis with culture specimens. This is usually accomplished by reducing the increased intracranial pressure (ICP) through surgical aspiration with or without drainage of the abscess pus. The surgical procedure chosen depends on several factors, including the location and type of abscess, multiplicity, and the medical condition of the patient. In addition, dexamethasone and hyperventilation may be required if brain herniation is imminent. The dexamethasone dose should be reduced as soon as the ICP is reduced because steroid administration may retard abscess capsule formation and decrease antibiotic concentrations within the abscess cavity. Antibiotic therapy should be started as soon as the diagnosis is made. Penicillin G or third-generation cephalosporins plus metronidazole are commonly given to treat both anaerobic and aerobic bacteria. The initial choice of antibiotic will vary on the basis of the suspected source of the brain organisms, which is most often either contiguous spread from a sinus or mastoid infection or hematogenous spread from a pulmonary, gastrointestinal, cardiac, or dental infection. Isolation and determination of the antibiotic sensitivities of the organism from abscess pus allow definitive antibiotic therapy. Patients should be managed in an intensive care unit. Phenytoin is often given to prevent seizures, which could further elevate the ICP. The duration of antimicrobial treatment is 4 to 8 weeks, during which time the patient should be monitored clinically and with repeated neuroimaging studies to ensure abscess resolution.

A lung abscess is an infectious pulmonary disease characterised by the presence of a pus-filled cavity within the lung parenchyma. The content of an abscess often drains into the airways spontaneously, leading to an air-fluid level visible on chest X-rays and CT scans. Primary lung abscesses occur in patients who are prone to aspiration or in otherwise healthy individuals; secondary lung abscesses typically develop in association with a stenosing lung neoplasm or a systemic disease that compromises immune defences, such as AIDS, or after organ transplantation. The organisms found in abscesses caused by aspiration pneumonia reflect the resident flora of the oropharynx. The most commonly isolated organisms are anaerobic bacteria (Prevotella, Bacteroides, Fusobacterium, Peptostreptococcus) or streptococci; in alcoholics with poor oral hygiene, the spectrum of pathogens includes Staphylococcus aureus, Streptococcus pyogenes and Actinomyces. Chest radiography and computed tomography (CT) are mandatory procedures in the diagnostic algorithm. Standard treatment for a lung abscess consists of systemic antibiotic therapy, which is based on the anticipated or proven bacterial spectrum of the abscess. In most cases, primary abscesses are successfully treated by calculated empiric antibiotic therapy, with an estimated lethality rate of less than 10 %. Secondary abscesses, despite targeted antimicrobial therapy, are associated with a poor prognosis, which depends on the patient's general condition and underlying disease; lethality is as high as 75 %. Negative prognostic factors are old age, severe comorbidities, immunosuppression, bronchial obstruction, and neoplasms. Surgical intervention due to failure of conservative treatment is required in only 10 % of patients, with a success rate of up to 90 % and postoperative mortality rates ranging between 0 and 33 %. Treatment success after endoscopic or percutaneous drainage is achieved in 73 to 100 % of cases, with an acceptable mortality rate (0-9 %). Georg Thieme Verlag KG Stuttgart · New York.

Recurrent diverticulitis has been reported in up to 30% to 40% of patients who recover from an episode of colonic diverticular abscess, so elective interval resection is traditionally recommended. The aim of this study was to review the outcomes of patients who underwent percutaneous drainage of colonic diverticular abscess without subsequent operative intervention. This was an observational study. This investigation was conducted at a tertiary care academic medical center and a single-hospital health system. Patients treated for symptomatic colonic diverticular abscess from 2002 through 2007 were included. The primary outcomes measured were complications, recurrence, and colectomy-free survival. Two hundred eighteen patients underwent percutaneous drainage of colonic diverticular abscesses. Thirty-two patients (15%) did not undergo subsequent colonic resection. Abscess location was pelvic (n = 9) and paracolic (n = 23), the mean abscess size was 4.2 cm, and the median duration of percutaneous drainage was 20 days. The comorbidities of this group of patients included severe cardiac disease (n = 16), immunodeficiency (n = 7), and severe pulmonary disease (n = 6). Freedom from recurrence at 7.4 years was 0.58 (95% CI 0.42-0.73). All recurrences were managed nonoperatively. Recurrence was significantly associated with an abscess size larger than 5 cm. Colectomy-free survival at 7.4 years was 0.17 (95% CI 0.13-0.21). This study was limited by its retrospective, nonexperimental design and short follow-up. In selected patients, observation after percutaneous drainage of colonic diverticular abscess appears to be a safe and low-risk management option.

A 50-year-old man with intractable anal pain attributed to proctalgia fugax underwent insertion of a sacral nerve stimulator via the right S3 vertebral foramen for pain control with good symptomatic relief. Thirteen months later, he presented with signs of sepsis. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a large presacral abscess. MRI demonstrated increased enhancement along the pathway of the stimulator electrode, indicating that the abscess was caused by infection introduced at the time of sacral nerve stimulator placement. The patient was treated with broad spectrum antibiotics, and the sacral nerve stimulator and electrode were removed. Attempts were made to drain the abscess transrectally using minimally invasive techniques but these were unsuccessful and CT guided transperineal drainage was then performed. Despite this, the presacral abscess progressed, developing enlarging gas locules and extending to the pelvic brim to involve the aortic bifurcation, causing hydronephrosis and radiological signs of impending sacral osteomyelitis. MRI showed communication between the rectum and abscess resulting from transrectal drainage. In view of the progressive presacral sepsis, a laparotomy was performed with drainage of the abscess, closure of the upper rectum and formation of a defunctioning end sigmoid colostomy. Following this, the presacral infection resolved. Presacral abscess formation secondary to an infected sacral nerve stimulator electrode has not been reported previously. Our experience suggests that in a similar situation, the optimal management is to perform laparotomy with drainage of the presacral abscess together with simultaneous removal of the sacral nerve stimulator and electrode.

The bacterial species found in pus aspirated from brain abscesses in two patients were typical of those found in dental sepsis. Subsequently apical-root abscesses were demonstrated in the upper jaws of both patients. This evidence strongly suggests that these cerebral abscesses were secondary to dental sepsis which could have spread from the teeth to the frontal lobes by several possible antaomical pathways.

Primary lung abscess caused by Staphylococcus lugdunensis.

PubMed

Chou, Deng-Wei; Lee, Chao-Tai

2017-11-01

Staphylococcus lugdunensis, a strain of coagulase-negative staphylococci, is part of the normal flora of human skin but can cause multiple infections at various sites. This microorganism has emerged as a major human pathogen. However, no study has reported primary lung abscess caused by S. lugdunensis. A 54-year-old alcoholic man without relevant past medical history was admitted because of primary lung abscesses. Empirical amoxicillin/clavulanate therapy was initially administered; however, the patient had persistent pleuritic chest pain and fever. He subsequently underwent resection of the lung abscess and removal of exudative pleural effusion on the fourth hospital day. Histopathologic examination confirmed the diagnosis of lung abscess, and colonies of gram-positive bacteria were identified. The culture specimen from the abscess was positive for S. lugdunensis, which was susceptible to amoxicillin/clavulanate, cefazolin, ciprofloxacin, clindamycin, erythromycin, oxacillin, teicoplanin, tetracycline, and vancomycin. Following resection and 3 weeks of amoxicillin/clavulanate therapy, the patient eventually recovered well without relapse. This case report is the first to describe S. lugdunensis as a cause of primary lung abscess; this microorganism should be considered a potential monomicrobial pathogen in primary lung abscess.

To assess ultrasonographically (US) guided needle aspiration of breast abscesses as an alternative to surgical incision and drainage. In our prospective study, 30 patients with 31 breast abscesses (one patient had bilateral breast abscess) underwent percutaneous breast abscess drainage under US guidance with local anaesthesia and oral antibiotics between 1 January 2004 and 31 March 2005. These patients consisted of 16 (53.3%) non-lactating and 14 (46.7%) lactating women, with ages ranging from 18 to 68 years (median, 28 years). The racial distribution comprised 26 (86.7%) Malays, three (10%) Chinese and one (3.3%) Indian. All patients had the chief complaint of breast swelling and 25 (83.3%) had breast pain. Clinically, 28 (93.3%) were found to have a palpable mass. Nine (30%) lesions were in the upper outer quadrant of the left breast. US diameters ranged from 1 to 15 cm (median, 4 cm). The pus volumes varied from 1 to 200 mL (median, 14 mL). Fifteen (50%) patients required only a single aspiration, 10 required multiple aspirations and five required incision and drainage. Those patients in whom needle aspiration failed had multiloculated lesions irrespective of abscess volume and size. Needle aspiration with ultrasound guidance is an effective treatment for breast abscess irrespective of abscess volume and size.

Population variability of the FimH type 1 fimbrial adhesin in Klebsiella pneumoniae.

FimH is an adhesive subunit of type 1 fimbriae expressed by different enterobacterial species. The enteric bacterium Klebsiella pneumoniae is an environmental organism that is also a frequent cause of sepsis, urinary tract infection (UTI), and liver abscess. Type 1 fimbriae have been shown to be critical for the ability of K. pneumoniae to cause UTI in a murine model. We show here that the K. pneumoniae fimH gene is found in 90% of strains from various environmental and clinical sources. The fimH alleles exhibit relatively low nucleotide and structural diversity but are prone to frequent horizontal-transfer events between different bacterial clones. Addition of the fimH locus to multiple-locus sequence typing significantly improved the resolution of the clonal structure of pathogenic strains, including the K1 encapsulated liver isolates. In addition, the K. pneumoniae FimH protein is targeted by adaptive point mutations, though not to the same extent as FimH from uropathogenic Escherichia coli or TonB from the same K. pneumoniae strains. Such adaptive mutations include a single amino acid deletion from the signal peptide that might affect the length of the fimbrial rod by affecting FimH translocation into the periplasm. Another FimH mutation (S62A) occurred in the course of endemic circulation of a nosocomial uropathogenic clone of K. pneumoniae. This mutation is identical to one found in a highly virulent uropathogenic strain of E. coli, suggesting that the FimH mutations are pathoadaptive in nature. Considering the abundance of type 1 fimbriae in Enterobacteriaceae, our present finding that fimH genes are subject to adaptive microevolution substantiates the importance of type 1 fimbria-mediated adhesion in K. pneumoniae.

Background: A brain stem abscess is a rare and severe medical condition. Here, we present a rare case of a brain stem abscess in a young pregnant woman, requiring acute stereotactic intervention. Case Description: A 36-year-old woman presented with a headache, nausea, and vomiting, and computed tomography showed a space-occupying lesion in the brain stem. She became shortly after comatose, and we decided to perform an acute stereotactic aspiration of the abscess. Soon after surgery, her neurological condition improved dramatically. Conclusion: A brainstem abscess is a life-threatening condition with a potentially good outcome if treated adequately. PMID:26543670

A 19-year-old male patient was diagnosed with S. sanguinis brain abscess of unknown etiopathology as a complication of subclinical endocarditis. While viridans streptococci are implicated in dental seeding to the heart, S. sanguinis brain abscesses are rare. Six previous cases of S. sanguinis brain abscess in the literature reported dental procedures and maxillofacial trauma. In our patient, there was no obvious source of infective endocarditis preceding the development of brain abscess. This demonstrates the importance of prompt diagnosis and initiation of antimicrobial therapy given the potential for long-term sequelae such as focal deficits and seizures.

Abscess incision and drainage in the emergency department--Part I.

Superficial abscesses are commonly seen in the emergency department. In most cases, they can be adequately treated by the emergency physician without hospital admission. Treatment consists of surgical drainage with the addition of antibiotics in selected cases. Incision is generally performed using local anesthesia, with intraoperative and postoperative systemic analgesia. Care must be taken to make a surgically appropriate incision that allows adequate drainage without injuring important structures. Postoperative care includes warm soaks, drains or wicks, analgesia, and close follow-up. Antibiotics are usually unnecessary. Complications of incision and drainage include damage to adjacent structures, bacteremic complications, misdiagnosis of such entities as mycotic aneurysms, and spread of infection owing to inadequate drainage. The infectious agents responsible for abscess formation are numerous and depend largely on the anatomic location of the abscess. Staphylococcus aureus accounts for less than half of all cutaneous abscesses. Anaerobic bacteria are common etiologic agents in the perineum and account for the majority of all cutaneous abscesses. Abscesses at specific locations involve special consideration for diagnosis and treatment and may require specialty consultation.

Surgical drainage and post operative lavage of large abdominal abscesses in six mature horses.

Six mature horses with large abdominal abscesses (defined as an abscess >15-20 cm in at least one dimension) were treated by surgical drainage and post operative lavage. The abscess was associated with previous intestinal surgery in one horse, and with Streptococcus equi spp. equi infection in the other 5. A Foley catheter was used to drain and lavage the abscess in all cases. The abscess was accessed by a ventral midline laparotomy in 5 cases and by standing flank laparoscopy in one. Two horses were subjected to euthanasia within 7 days due to persistent or recurrent colic. The other 4 horses survived. Lavage of the abscess was continued for a median time of 19 days. Antibacterial therapy was continued until the plasma fibrinogen concentration was normal (median 47 days). Follow-up information was obtained at a median of 1.8 years. All 4 horses were alive at the time of follow-up; 2 horses had suffered one or more bouts of colic that had responded to medical treatment. © 2011 EVJ Ltd.

Apical Periodontitis (AP) is an inflammatory disease that affects the tissues surrounding the root end of a tooth. The disease which is caused by endodontic infections presents in different clinical ways including development of an acute abscess. Recent studies have provided information suggesting role of a multitude of factors in pathogenesis of acute apical abscess (AAA). In this case-control study, our goal was to evaluate the frequency and potential role of two common polymorphisms of toll like receptor-4 (TLR-4) gene; Thr399Ile (1196 C>T) and Asp299Gly (+896 A>G), in 50 patients with AAA as cases and 50 patients with asymptomatic apical periodontitis (AAP) as controls. Saliva sample containing mucosal epithelial cells was used for DNA extraction. Polymorphisms were detected by Tetra-ARMS (Amplification Refractory Mutation System) PCR method. Statistical analyses were carried out in SPSS 21 software. Homozygous wild type (CC) and heterozygous (CT) genotypes of Thr399Ile polymorphism were detected in 84% and 16% of AAA patients respectively. In controls, respective ratios were 94% (CC) and 6% (CT). Observed difference was not statistically significant ( P >0.05) for distribution of these genotypes. The mutant homozygous (TT) genotype of this polymorphism was identified in neither of the participants. Overall, T allele frequency was obtained 8% in AAA and 3% in AAP (OR=2.6, 95% CI; 0. 6-10.6, p >0.05). For Asp299Gly polymorphism, no individual was detected with the mutant allele in case or control groups. Our results indicated a possible role for Thr399Ile polymorphism in acute presentations of abscess in AAA. However, the impact of this polymorphism needs to be more assessed in future studies. Key words: Genetic polymorphism, periapical abscess, periapical periodontitis, toll-like receptor 4.

Porphyromonas gingivalis produces hydrogen sulfide (H2S) from l-cysteine. However, the role of H2S produced by P. gingivalis in periodontal inflammation is unclear. In this study, we identified the enzyme that catalyses H2S production from l-cysteine and analysed the role of H2S using a mouse abscess model. The enzyme identified was identical to methionine γ-lyase (PG0343), which produces methyl mercaptan (CH3SH) from l-methionine. Therefore, we analysed H2S and CH3SH production by P. gingivalis W83 and a PG0343-deletion mutant (ΔPG0343) with/without l-cysteine and/or l-methionine. The results indicated that CH3SH is produced constitutively irrespective of the presence of l-methionine, while H2S was greatly increased by both P. gingivalis W83 and ΔPG0343 in the presence of l-cysteine. In contrast, CH3SH production by ΔPG0343 was absent irrespective of the presence of l-methionine, and H2S production was eliminated in the absence of l-cysteine. Thus, CH3SH and H2S production involves different substrates, l-methionine or l-cysteine, respectively. Based on these characteristics, we analysed the roles of CH3SH and H2S in abscess formation in mice by P. gingivalis W83 and ΔPG0343. Abscess formation by P. gingivalis W83, but not ΔPG0343, differed significantly in the presence and absence of l-cysteine. In addition, the presence of l-methionine did not affect the size of abscesses generated by P. gingivalis W83 and ΔPG0343. Therefore, we conclude that H2S produced by P. gingivalis does not induce inflammation; however, H2S enhances inflammation caused by CH3SH. Thus, these results suggest the H2S produced by P. gingivalis plays a supportive role in inflammation caused by methionine γ-lyase.

Background Apical Periodontitis (AP) is an inflammatory disease that affects the tissues surrounding the root end of a tooth. The disease which is caused by endodontic infections presents in different clinical ways including development of an acute abscess. Recent studies have provided information suggesting role of a multitude of factors in pathogenesis of acute apical abscess (AAA). In this case-control study, our goal was to evaluate the frequency and potential role of two common polymorphisms of toll like receptor-4 (TLR-4) gene; Thr399Ile (1196 C>T) and Asp299Gly (+896 A>G), in 50 patients with AAA as cases and 50 patients with asymptomatic apical periodontitis (AAP) as controls. Material and Methods Saliva sample containing mucosal epithelial cells was used for DNA extraction. Polymorphisms were detected by Tetra-ARMS (Amplification Refractory Mutation System) PCR method. Statistical analyses were carried out in SPSS 21 software. Results Homozygous wild type (CC) and heterozygous (CT) genotypes of Thr399Ile polymorphism were detected in 84% and 16% of AAA patients respectively. In controls, respective ratios were 94% (CC) and 6% (CT). Observed difference was not statistically significant (P>0.05) for distribution of these genotypes. The mutant homozygous (TT) genotype of this polymorphism was identified in neither of the participants. Overall, T allele frequency was obtained 8% in AAA and 3% in AAP (OR=2.6, 95% CI; 0. 6-10.6, p>0.05). For Asp299Gly polymorphism, no individual was detected with the mutant allele in case or control groups. Conclusions Our results indicated a possible role for Thr399Ile polymorphism in acute presentations of abscess in AAA. However, the impact of this polymorphism needs to be more assessed in future studies. Key words:Genetic polymorphism, periapical abscess, periapical periodontitis, toll-like receptor 4.

Prophylactic antibiotics are frequently administered for transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC). In patients without previous biliary instrumentation, infection risk from TACE is low. We hypothesized that there is a negligible rate of infection in these patients without prophylactic antibiotics. We reviewed consecutive patients undergoing TACE between 7/1/2013-6/15/2016. All patients had an intact Sphincter of Oddi, received no peri-procedural antibiotics, and had 30+ days follow-up. Level of arterial selection was recorded. Baseline Child-Pugh (CP) and Barcelona Clinic Liver Cancer (BCLC) scores were recorded. The primary outcome measure was the absence of clinical or imaging findings of hepatic abscess within 30 days. A total of 171 patients underwent 235 TACE procedures. CP scores were A (n = 109), B (n = 47), and C (n = 15). BCLC scores were 0 (n = 1), A (n = 108), B (n = 47), and C (n = 15). TACE was performed segmentally (n = 208) or lobar (n = 27). Three patients died of non-infectious causes before 30 days. No hepatic abscesses developed in evaluable patients: 0/232 infusions. In patients with HCC and an intact Sphincter of Oddi, TACE was performed safely without prophylactic antibiotics. The majority of the patients were BCLC and CP A/B. Additional study of BCLC and CP C patients is warranted. © 2018 Wiley Periodicals, Inc.

Study populations and casemix: influence on analysis of postoperative outcomes.

PubMed

Isbister, W H

2000-04-01

The importance of patient casemix as a determinant of surgical outcome is now being recognized. The present study was undertaken in order to compare the presentation and outcomes in colorectal patients managed surgically by the same surgeon, in the same way, in different settings. Colorectal outcome data from the University Department of Surgery in Wellington and the King Faisal Specialist Hospital in Riyadh were analysed in order to determine casemix differences between the two hospitals. Data relating to the type of surgery, the surgeon, the patient's disease, the operation performed and the postoperative complications were compared. Specific colorectal clinical indicators were compared for two commonly performed operations for rectal cancer: anterior resection and abdomino-perineal resection of the rectum. Wellington patients were slightly older and there were more females. Emergency surgery was more frequent in Wellington. Left hemicolectomy, sigmoid colectomy, abscess drainage and pilonidal surgery were more common in Wellington whereas abdomino-perineal resection and anterior resection of the rectum, stoma closure, fistula surgery, seton insertion, restorative proctocolectomy and ileostomy were undertaken more frequently in Riyadh. More complex anal fistulas were managed in Riyadh. Condylomata accuminata, pilonidal abscess, anorectal abscess, rectal prolapse and diverticular disease were rarely seen in Riyadh. There were more postoperative pulmonary and cardiac complications in Wellington. Patients having anterior resection of the rectum were younger in Riyadh and there were proportionally more females. There were some obvious numerical outcome differences in postoperative atelectasis, wound infection, anastomotic leak and deep vein thrombosis rates but none of these reached statistical significance except atelectasis. In Riyadh the usual male-to-female ratio of patients undergoing abdomino-perineal resection was reversed but, again, none of the numerical outcome differences observed reached statistical significance except postoperative atelectasis and intraabdominal abscess. Although not statistically significant, the results of the present study suggest that when the same surgeon operates using the same technique in different communities, the outcomes may be different. Care should thus be taken when comparing different populations with different casemixes before definitive conclusions are made in comparative studies.

Because subareolar breast abscess has a high recurrence rate, a more effective imaging technique is needed to comprehensively visualize the lesions and guide surgery. We performed a high-resolution MRI technique using a microscopy coil to reveal the characteristics and extent of subareolar breast abscess. High-resolution MRI has potential diagnostic value in subareolar breast abscess. This technique can be used to guide surgery with the aim of reducing the recurrence rate.

2010-01-01

Fungal abscesses of the parotid gland are rare, and cases arising within parotid neoplasms have not been described previously. This report conveys our experience managing such an entity, which is further distinguished by its occurrence in an immunocompetent host. A 59-year-old man experienced multiple recurrences of a parotid fungal abscess requiring repeated drainage procedures. Definitive excision ultimately demonstrated Candida glabrata infecting a Warthin tumor. This case is the first report of a parotid neoplasm presenting as a fungal abscess. It contributes to the scant literature on fungal abscesses of the parotid, which previously has only been described in debilitated hosts and without an associated neoplasm. The case also expands the spectrum of disease associated with C. glabrata. Warthin tumor may be an occult etiology for a parotid fungal abscess, and definitive diagnosis and therapy may require parotidectomy.

Orthodontic elastic separator-induced periodontal abscess: a case report.

PubMed

Becker, Talia; Neronov, Alex

2012-01-01

Aim. Orthodontic elastic bands were proposed as being the source of gingival abscesses that can rapidly lead to bone loss and teeth exfoliation. We report an adolescent, otherwise, healthy patient whose periodontal status was sound. Shortly after undergoing preparations for orthodontic treatment consisting of orthodontic separators, he presented with a periodontal abscess for which there was no apparent etiology. A non-orthoradial X-ray was inconclusive, but an appropriate one revealed a subgingival orthodontic separator as the cause of the abscess. Removal of the separator and thorough scaling led to complete resolution of the abscess, but there was already residual mild damage to the alveolar bone. Summary. Failure to use appropriate imaging to reveal the cause of gingival abscesses can result in the delay of implementing treatment and halting irreversible alveolar bone loss. An inflammatory process restricted to the gingiva and refractive to conventional therapy should raise the possibility of a foreign body etiology.

Actinomyces meyeri brain abscess following dental extraction

Clancy, U; Ronayne, A; Prentice, M B; Jackson, A

2015-01-01

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

With the progress of antibiotic therapy, the mortality of lung abscess has been improved, and surgical intervention has declined. However, surgery is still required in selected cases that are intractable to antibiotic treatment. Video-assisted thoracoscopic surgery (VATS) is beneficial for treatment and/or diagnosis of pulmonary disease as it provides a less invasive surgical technique and reduces prolongation of post-operative recovery. However, the indication of VATS lobectomy for lung abscess is controversial as a result of particular complications, i.e. wet lung, intrapleural adhesion and ease of bleeding. We herein report a rare combination of lung abscess and osteomyelitis of mandible resulting from the same pathogen successfully treated with VATS lobectomy. We propose VATS lobectomy for lung abscess. This procedure might be the best treatment candidate for selected cases of lung abscess. © 2014 John Wiley & Sons Ltd.

Gastric subepithelial lesion complicated with abscess: Case report and literature review

PubMed Central

Kim, Sung Bum; Oh, Myung Jin; Lee, Si Hyung

2015-01-01

Gastric abscess is a localized pyogenic inflammation of the gastric wall, which is a rare form of suppurative gastritis. The rarity of gastric abscess may be associated with the difficulty of early diagnosis and high mortality as a result. In general, subepithelial lesions (SELs) of the stomach are incidentally detected during the course of upper endoscopy without specific clinical symptoms and signs. However, some gastric SELs present rarely as a form of hemorrhage, obstruction, perforation, and abscess. Here we report a 45-year-old man with gastric SEL presenting as a gastric abscess, which was diagnosed as an ectopic pancreas of the stomach, along with a review of the literature. Although gastric SEL presenting as an abscess is known as a serious and life-threatening lesion, the patient made a complete recovery through surgical resection as well as medical treatment.

Breast abscess: evidence based management recommendations.

PubMed

Lam, Elaine; Chan, Tiffany; Wiseman, Sam M

2014-07-01

Literature review was carried out and studies reporting on treatment of breast abscesses were critically appraised for quality and their level of evidence using the Strength of Recommendation Taxonomy guidelines, and key recommendations were summarized. Needle aspiration either with or without ultrasound guidance should be employed as first line treatment of breast abscesses. This approach has the potential benefits of: superior cosmesis, shorter healing time, and avoidance of general anaesthesia. Multiple aspiration sessions may be required for cure. Ultrasound-guided percutaneous catheter placement may be considered as an alternative approach for treatment of larger abscesses (>3 cm). Surgical incision and drainage should be considered for first line therapy in large (>5 cm), multiloculated, or long standing abscesses, or if percutaneous drainage is unsuccessful. All patients should be treated concurrently with antibiotics. Patients with recurrent subareolar abscesses and fistulas should be referred for consideration of surgical treatment.

Further refinement of the Escherichia coli brain abscess model in rat.

PubMed

Nazzaro, J M; Pagel, M A; Neuwelt, E A

1992-09-01

The rat brain abscess model provides a substrate for the modeling of delivery of therapeutic agents to intracerebral mass lesions. We now report refinement of the Escherichia coli brain abscess model in rat. A K1 surface antigen-negative E. coli isolated from human blood culture was stereotaxically inoculated into deep brain sites. Histopathologic analyses and quantitative cultures demonstrated the consistent production of lesions. No animal in this consecutive series developed meningitis, ventriculitis or sepsis. By contrast, prior experience with E. coli abscess production resulted in 25% failure rate of abscess production or death from sepsis. This improvement in the model may be attributable to specific characteristics of the bacteria used, modification of the inoculation method or the intracerebral placement technique. The present work suggests a reliable and consistent brain abscess model, which may be further used to study brain suppuration.

Greater complexity of liver surgery is not associated with an increased incidence of liver-related complications except for bile leak: an experience with 2,628 consecutive resections.

Advances in technique, technology, and perioperative care have allowed for the more frequent performance of complex and extended hepatic resections. The purpose of this study was to determine if this increasing complexity has been accompanied by a rise in liver-related complications. A large prospective single-institution database of patients who underwent hepatic resection was used to identify the incidence of liver-related complications. Liver resections were divided into an early era and a late era with equal number of patients (surgery performed before or after 18 May 2006). Patient characteristics and perioperative factors were compared between the two groups. Between 1997 and 2011, 2,628 hepatic resections were performed, with a 90-day morbidity and mortality rate of 37 and 2 %, respectively. We identified higher rates of repeat hepatectomy (12.2 vs 6.1 %; p < 0.001), two-stage resection (4.0 vs 1 %; p < 0.001), extended right hepatectomy (17.6 vs 14.6 %; p = 0.04), and preoperative portal vein embolization (9.1 vs 5.9 %; p < 0.001) in the late era. The incidence of perihepatic abscess (3.7 vs 2.1 %; p = 0.02) and hemorrhage (0.9 vs 0.3 %; p = 0.045) decreased in the late era and the incidence of hepatic insufficiency (3.1 vs 2.6 %; p = 0.41) remained stable. In contrast, the rate of bile leak increased (5.9 vs 3.7 %; p = 0.011). Independent predictors of bile leak included bile duct resection, extended hepatectomy, repeat hepatectomy, en bloc diaphragmatic resection, and intraoperative transfusion. The complexity of liver surgery has increased over time, with a concomitant increase in bile leak rate. Given the strong association between bile leak and other poor outcomes, the development of novel technical strategies to reduce bile leaks is indicated.

Abscesses commonly occur among people who inject drugs (PWID). However, whether the risks are comparable between males and females, and the impact of sex work on abscess risk is unclear. The goal of this study was to examine the contemporary associations of gender and sex work with the risk of abscesses in PWID. Combining data from two cross-sectional studies conducted in the Greater Boston Area with people at risk for HIV and hepatitis C virus (HCV), we used the following inclusion criteria: age 18-45 years and report of illicit or non-prescription drug injection within the 30 days prior to the survey. Information on demographics, injection-mediated risks, and sexual behaviors was collected using Audio Computer-Assisted Self-Interview Software. Multivariable logistic regressions were used to model associations. The study sample included 298 people including 30% were female. Females were more likely than men to report sex work (28% vs. 16%, p = .012) and abscess during their lifetime (55% vs. 37% p = .004). Among the females, engaging in sex work increased by >5-fold the odds of reporting abscesses [Adjusted odds ratio 5.42; 95% CI: 1.27, 23.10]. There was no association between sex work and abscesses among men. We found a female-specific association between sex work, injection drug use, and abscesses among PWID. Although the cross-sectional designs precluded causal inferences, longitudinal studies could enhance understanding of gender-associated risks for abscesses and inform the development of harm reduction interventions.

Does pilonidal abscess heal quicker with off-midline incision and drainage?

2011-06-01

No clinical trials have been done to guide the surgeon in the optimal technique of draining a pilonidal abscess. The aim of our study was to investigate whether the location of the incision influences wound healing. Electronic records from the surgical database at our 200-bed district general hospital were reviewed for operative technique (midline vs. lateral) for patients who underwent incision and drainage for acute pilonidal abscess between January 2003 and February 2010. These patients were admitted from the Emergency Department with a pilonidal abscess, underwent operative drainage, and returned for follow-up. The main outcome measure was wound healing time. Two hundred and forty-three pilonidal abscesses were drained, 134 with a lateral and 74 with a midline incision. All patients underwent simple longitudinal incision. No patient underwent de-roofing, marsupialisation, or closure. Forty-eight patients with midline drainage who returned for follow-up were matched for gender, age, and microbiology culture results with patients who underwent lateral drainage. Almost all were drained under general anesthesia with a median postoperative stay of 1 day. The overall length of follow-up was the same in both groups (P = 0.13). Abscesses that did not heal were followed-up for the same period of time irrespective of incision type (P = 0.48). Abscesses that healed after midline incision took approximately 3 weeks longer than those drained via a lateral incision (P = 0.02). Our study has limitations since it was a retrospective study that did not capture patients whose abscess drained spontaneously or were drained in the emergency department. Pilonidal abscess should be drained away from the midline.

To explore possible reasons for the incidence of a pituitary abscess following transsphenoidal surgery and determine the most effective treatment. A series of 12 patients who had undergone transsphenoidal surgery in other hospitals before being treated at Peking Union Medical College Hospital were reviewed. The presence of a pituitary abscess was confirmed when pus was intraoperatively observed within the sella turcica. All patients were treated with debridement of the abscess, nine among whom through a transsphenoidal approach and the other three via a craniotomy, followed by antibiotic treatment and hormone replacement therapy. The mean follow-up time was 27.0 months (range from 3.0 to 79.0 months). Headache (92%), panhypopituitarism (58%) and visual disturbance (50%) were the most common clinical indicators of a pituitary abscess. Imaging tests demonstrated a pituitary mass in all patients, with seven (58%) manifested with typical magnetic resonance features of an abscess. Ten patients (83%) were correctly diagnosed preoperatively. During surgical exploration, six presented with severe inflammation or an abscess within the sphenoidal sinus. Causative organisms were identified in five patients (42%). After surgical and antibiotic therapies, all patients fully recovered except for two presenting with severe visual impairment. Six patients (50%) required hormone replacement therapy. Retrograde infection from the sphenoid sinus may be a vital mechanism underlying the formation of a pituitary abscess following transsphenoidal surgery. Debridement of the abscess through surgical approaches combined with antibiotic treatment has been found to yield positive outcomes. Copyright © 2014 Elsevier B.V. All rights reserved.

Pneumothorax secondary to septic pulmonary embolism (SPE) is rare but life-threatening. We herein report a long-term hemodialysis patient with psoas abscess caused by methicillin-resistant Staphylococcus aureus, associated with other muscle and splenic abscesses and SPE. Intravenous vancomycin treatment and percutaneous drainage of the psoas abscess rapidly improved her condition. However, the SPE lesions continued to increase, and right-sided pneumothorax occurred 10 days after treatment. The pneumothorax resolved after two months and SPE and all abscesses after four months of treatment. Since late-onset pneumothorax caused by SPE can occur despite successful treatment of the primary infection, care should be taken with such patients.

Lung abscess caused by Mycoplasma pneumoniae.

A 10-year-old boy with West syndrome was referred to hospital because of high fever and cough. Chest X-ray and computed tomography showed consolidation with an abscess in the right upper lobe. Laboratory data indicated cytokine storm. Various antibacterial agents and additional corticosteroid were unable to control the hypercytokinemia, which was suppressed after cyclosporine A was started. The lung abscess remained, however, and right upper lobectomy was performed. Culture from the abscess showed no growth, while polymerase chain reaction assay indicated Mycoplasma pneumoniae DNA. Serum passive agglutinin titer for M. pneumoniae was significantly elevated in the convalescent phase. These findings are strong evidence that the lung abscess was caused by M. pneumoniae infection. © 2015 Japan Pediatric Society.

2017-03-01

Superior pediatric orbital subperiosteal abscesses (SPAs) are less common than medial ones, and clinical features specific to patients with superior SPAs have not been well defined. Clinical characteristics between patients with superior and medial SPAs are compared to determine whether superior location is a risk factor for surgical intervention. Retrospective cohort study. The target population consisted of patients diagnosed with an SPA and seen by the pediatric otolaryngology service at a tertiary children's hospital between January 2010 and October 2014. Imaging characteristics including proptosis, hypoglobus, intraorbital air, and abscess volume as well as treatment interventions were reviewed. Forty patients between 5 and 17 years of age treated for an orbital SPA were identified. Thirteen patients were identified as having superior SPAs; 27 had medial SPAs. The average ages in the two groups were 10.92 and 9.26 years, respectively. The odds ratio for surgical treatment per each increasing year of age was 1.5 (P = .004). The proportion of patients requiring surgery was significantly different between the groups (12/13 superior vs. 13/27 medial, P = .01). The predominant organism group cultured in surgical patients was Streptococcus anginosus (8/24, 29.17%). Superior SPA patients had significantly more proptosis, hypoglobus, and abscess volume on computed tomography scan. Patients with superior SPAs may present with more advanced disease, leading to a higher rate of characteristics such as proptosis, hypoglobus, and intraorbital air, factors that would predispose to surgical drainage. We found that abscess volume was the most predictive of surgery. 4 Laryngoscope, 127:735-740, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

Studies on methicillin-resistant Staphylococcus aureus (MRSA) infections have typically focused on pediatric and adult populations at urban tertiary care hospitals. Limited data exist on MRSA rates in skin and soft tissue infections (SSTI) in suburban community hospital pediatric emergency departments (PED). To describe the prevalence of MRSA in SSTIs in a contemporary suburban community hospital PED population. Patients 0-21 years old with SSTI wound cultures who were seen at our PED from 2003-2007 were studied. Data analyzed included type of infection (abscess vs. non-abscess), site of infection, and culture results. Chi-squared and t-tests were used as appropriate; p < 0.05 was considered significant. During the study period, 204 cultures were obtained for SSTIs, 11 of which were contaminants. The subjects had a mean age of 12.9 years (SD 6.8 years); 60% were male. The prevalence of MRSA was 27%; MRSA was present in 30% of abscesses vs. 2.2% of non-abscess SSTI (p < 0.005). By year, the prevalence of MRSA was 10% in 2003, 31% in 2004, 33% in 2005, 31% in 2006, and 29% in 2007. No differences between MRSA and non-MRSA infections were present for gender, age, or site of infection. At our suburban community hospital pediatric ED, MRSA was present in 30% of all SSTI wound cultures; MRSA was unlikely with non-abscess SSTI. Our overall MRSA prevalence data among SSTIs are consistent with previously published reports in pediatric ED populations but may be less than those reported in the adult literature.

Retropharyngeal abscess commonly develops among infants and small children, and is associated with the severe inflammation of the retropharyngeal lymph nodes located in the retropharyngeal space. Retropharyngeal abscess causes cervical pain, swelling, contracture of the neck, and in rare cases inflammatory torticollis, all of which result from an inflammatory process that irritates the cervical muscles, nerves or vertebrae. Here we report a rare case of retropharyngeal abscess with a complication of torticollis. A 4-year-old girl suffered from severe retropharyngeal abscess spreading through the deep cervical fascia, as judged by magnetic resonance imaging of the neck. Blood analysis showed high degree of inflammatory reactions, and so the patient was transferred to our hospital ward. The inflammation caused spasms of the prevertebral muscles, eventually leading to torticollis. The surgical drainage was performed immediately under general anesthesia, and an anti-inflammation therapy with intravenously administered meropenem trihydrate and clindamycin was used together with traction therapy to relieve the symptoms of the patient. We must be careful about the existence of epidural abscess and infectious spondylitis when the retropharyngeal abscess causes torticollis. In conclusion, an anti-inflammation therapy using antibiotics, along with traction therapy, was effective to relieve the symptoms. In addition to repeated clinical examinations, cooperation with orthopedists and careful follow-up are necessary. We also discussed the relationship between acute torticollis and retropharyngeal abscess.

Increased Levels of S100A8/A9 in Patients with Peritonsillar Abscess: A New Promising Diagnostic Marker to Differentiate between Peritonsillar Abscess and Peritonsillitis.

Peritonsillar abscess (PTA) is a very frequent reason for urgent outpatient consultation and otolaryngological hospital admission. Early, correct diagnosis and therapy of peritonsillar abscess are important to prevent possible life-threatening complications. Based on physical examinations, a reliable differentiation between peritonsillar cellulitis and peritonsillar abscess is restricted. A heterodimeric complex called calprotectin consists of the S100 proteins A8 and A9 (S100A8/A9) and is predominantly expressed not only in monocytes and neutrophils but also in epithelial cells. Due to its release by activated phagocytes at local sites of inflammation, we assumed S100A8/A9 to be a potential biomarker for peritonsillar abscess. We examined serum and saliva of patients with peritonsillitis, acute tonsillitis, peritonsillar abscess, and healthy controls and found significantly increased levels of S100A8/A9 in patients with PTA. Furthermore, we could identify halitosis, trismus, uvula edema, and unilateral swelling of the arched palate to be characteristic symptoms for PTA. Using a combination of these characteristic symptoms and S100A8/A9 levels, we developed a PTA score as an objective and appropriate tool to differentiate between peritonsillitis and peritonsillar abscess with a sensitivity of 92% and specificity of 93%.

Our purpose was to review needle aspiration of breast abscesses and identify factors associated with treatment by aspiration alone versus aspiration with surgical incision and drainage (I/D). This Institutional Review Board-approved, retrospective review of the breast ultrasound database from 2008 to 2010 identified 40 patients (41 abscesses) who underwent aspiration, with or without I/D. Demographics, imaging, number of aspirations, and microbiology were reviewed. Twenty-two abscesses underwent aspiration only, 16 > 3 cm, 6 ≤ 3 cm (mean 4.3 cm, range 0.9-10 cm). Known risk factors included lactational (11), 3 weeks post partum (1), pregnancy (1), recent biopsy/lumpectomy (5). Nineteen abscesses underwent aspiration and I/D, 15 > 3 cm, 4 ≤ 3 cm (mean 4.1 cm, range 2.2-7.5 cm). Known risk factors included lactational (4), recurrent subareolar abscess (4), diabetes (3), hydradenitis suppuritiva (1), nipple piercing (2), smoking (1), pregnancy (1), HIV (1), and lumpectomy (1). Identified reasons for I/D included lack of improvement/recurrence (12), fistula (3), and one electively after clinical improvement of a recurrent subareolar abscess. Abscesses associated with pregnancy and lactation or breast biopsy are effectively managed with aspiration, even when large. Recurrence, chronicity, or fistula may require surgical intervention. © 2014 Wiley Periodicals, Inc.

Despite advances in surgical techniques in the management of the brain abscess, continuous systemic long-term antibiotics are necessary and crucial. This study was designed to evaluate the effect of intracavity administration of high-dose antibiotics on the course of antibiotic therapy. Between 2003 and 2013, 55 patients with bacterial brain abscesses (83 abscesses) were treated with stereotactic aspiration and intracavity injection of high-dose antibiotics combined with a short course systemic antibiotic therapy. Antibiotics of one-eighth daily systemic dosage were injected into the abscess cavity after stereotactic aspiration and intravenous antibiotics were given in all patients for 3 to 4 weeks. The results of the group treated with stereotactic aspiration and intracavity injection of antibiotic solution were compared to the results of our previous patients treated by stereotactic aspiration only. Thirty-nine males and 16 females (age ranging from 1.5 to 76 years; mean age 38.7 years) were included in this study. During the follow-up (mean 26.2 months, ranging from 6 to 72 months), all the abscesses subsided with no recurrence. No adverse effects related to topical use of antibiotics occurred. At the end of follow-up, 38 patients had good outcomes, 11 had mild neurological deficits, 3 had moderate deficits, 1 was in vegetative state, and 2 died of accidents not related to brain abscesses. Compared with conventional stereotactic aspiration and drainage, intracavity injection of antibiotics shorted the course of consecutive systemic intravenous antibiotics by average 10.8 days without an increase of the recurrence rate of abscesses. Our results indicate that topical application of antibiotics into the brain abscess cavity helps to reduce the length of systemic antibiotic therapy, decreases the abscess recurrence rate, avoids the side effects of long-term high dose antibiotics, shortens the hospitalization and reduces treatment costs.

Periodontal abscess during supportive periodontal therapy: a review of the literature.

PubMed

Silva, Geraldo L M; Soares, Rodrigo V; Zenóbio, Elton G

2008-09-01

The aim of this review is to present the current status of the occurrence and management of a periodontal abscess during supportive periodontal therapy (SPT). A periodontal abscess depicts typical features and has been described in patients under SPT in clinical trials. Common periodontal pathogens have been observed in this lesion and some etiologic factors may be responsible for its recurrence. This condition can be isolated or associated with factors that can change the prognosis of affected teeth. Although it has been frequently noticed in untreated periodontitis, the periodontal abscess can also occur in patients under SPT and has been regarded as one of the possible complications of SPT. Patients with a high susceptibility to periodontal disease lost more teeth than those with a healthy periodontium. Early diagnosis and appropriate intervention for periodontal abscesses in patients under SPT are extremely important for the management of the periodontal abscess since this condition can lead to loss of the involved tooth. A single case of a tooth diagnosed with periodontal abscess that responds favorably to adequate treatment does not seem to affect its longevity. An accurate diagnosis and adequate treatment can preserve the longevity of affected teeth.

Appendicitis is the most common abdominal inflammatory process in children which were sometimes followed by complications including intra-abdominal abscess. This later needs classically a surgical drainage. We evaluated the efficacy of antibiotic treatment and surgical drainage. Hospital records of children treated in our unit for intra-abdominal post appendectomy abscesses over a 6 years period were reviewed retrospectively. This study investigates a series of 14 children from 2 to 13 years of age with one or many abscesses after appendectomy, treated between 2002 and 2007. Seven underwent surgery and the others were treated with triple antibiotherapy. The two groups were comparable. For the 7 patients who receive medical treatment alone, it was considered efficient in 6 cases (85%) with clinical, biological and radiological recovery of the abscess. There was one failure (14%). The duration of hospitalization from the day of diagnosis of intra-abdominal abscess was approximately 10.28 days (range 7 to 14 days). In the other group, the efficacy of treatment was considered satisfactory in all cases. The duration of hospitalization was about 13 days (range: 9 to 20). Compared to surgical drainage, antibiotic management of intra-abdominal abscesses was a no invasive treatment with shorter hospitalization.

to study the diagnosis and treatment of enterococcus faecium lung abscess. a retrospective analysis of one case of Enterococcus faecium lung abscess and literature review was conducted. this patient suffered from cough and sputum over 6 months and complicated with hemoptysis over 3 months. Pulmonary embolism and lung cancer were suspected initially. After 2 times of CT-guided percutaneous transthoracic needle aspiration biopsy the diagnosis of pneumonia was made in other hospitals. However, the consolidation in the lung progressed and cavity appeared although antibiotic therapy was conducted. After admission to our hospital, CT-guided percutaneous transthoracic needle aspiration biopsy was made and the lung tissue was sent for bacterial culture. Enterococcus faecium was cultured and it was susceptible to vancomycin, teicoplanin and linezolid. The disease improved significantly after treatment with these 3 antibiotics in turn. In addition, 13 cases of enterococcus pneumonia or lung abscess were reviewed, including 3 cases of enterococcus faecium lung abscess. enterococcus faecium is rarely a pathogen for lung abscess. The diagnosis of enterococcus faecium lung abscess could be confirmed by lung biopsy and bacterial culture of lung tissue which could also provide the susceptibility of antibiotics and guide the antibiotic therapy.

Lung abscess following flexible bronchoscopy is a rare and sometimes fatal iatrogenic complication. Here, we report the first case of a lung abscess caused by multidrug-resistant Capnocytophaga sputigena following bronchoscopy. A 67-year-old man underwent bronchoscopy to evaluate a lung mass. Seven days after transbronchial lung biopsy, he presented with an abscess formation in a lung mass. Empirical antibiotic therapy, including with garenoxacin, ampicillin/sulbactam, clindamycin and cefepime, was ineffective. Percutaneous needle aspiration of lung abscess yielded C. sputigena resistant to multiple antibiotics but remained susceptible to carbapenem. He was successfully treated by the combination therapy with surgery and with approximately 6 weeks of intravenous carbapenem. Finally he was diagnosed with a lung abscess with adenocarcinoma expressing high levels of programmed cell death ligand 1. The emergence of multidrug-resistant Capnocytophaga species is a serious concern for effective antimicrobial therapy. Clinicians should consider multidrug-resistant C. sputigena as a causative pathogen of lung abscess when it is refractory to antimicrobial treatment.

Neonatal mastitis and neonatal breast abscess are uncommon. Although well described in the pediatric and surgical literature, there is a paucity of reports describing their sonographic features. To describe and illustrate the sonographic features of neonatal mastitis and neonatal breast abscess. We reviewed the medical database of a large children's health-care center from 2000 through 2008 for patients presenting in the first 8 weeks of life with mastitis. The findings were correlated with clinical presentation and course, laboratory findings and clinical outcome. Four neonates (three girls and one boy) presented with mastitis. They all had prominent breast buds on the affected side with poorly defined margins, slightly more echogenic focally or diffusely compared to normal with hyperemia on color flow Doppler US. The surrounding subcutaneous tissue was thick and echogenic. Two abscesses presented as avascular areas without color flow on Doppler US, subtly increased through-transmission and surrounding hyperemia. One abscess was of increased echogenicity while the other was anechoic. Neonatal mastitis and breast abscess are unusual diseases that should be appropriately treated with antibiotics and drainage to avoid generalized sepsis, breast hypoplasia, and scarring. US is useful in distinguishing mastitis from breast abscess and guiding treatment options.

Realisation of ultrasound-guided needle under local anesthesia by the radiologist and washing the cavity with physiological serum. Forty patients had lactational abscesses at an average of 10 weeks post-partum. Thirty-four patients were treated by needle aspiration, of which 2 had first surgical drainage. The average size of the abscess was 41.2mm. The success rate of needle aspiration was 91.2%. No cases of recurrence were observed, however, there were 5 fistulisations. In all, 91.2% were treated on an outpatient basis. In 87.8% of cases, breastfeeding was continued on the healthy side and in 48.5% of cases on the affected side. The major risk factor for abscess was mastitis in 91.1% of cases. Ultrasound guidance of needle aspiration should be gold standard for the treatment of lactational breast abscesses to continue breastfeeding including the affected side. Copyright © 2015.

Viral-bacterial and bacterial synergism have been suggested to contribute to the pathogenesis of several human diseases. This study sought to investigate the possible associations between 9 candidate endodontic bacterial pathogens and 9 human viruses in samples from acute apical abscesses. DNA extracts from purulent exudate aspirates of 33 cases of acute apical abscess were surveyed for the presence of 9 selected bacterial species using a 16S ribosomal RNA gene-based nested polymerase chain reaction (PCR) approach. Single or nested PCR assays were used for detection of the human papillomavirus (HPV) and herpesviruses types 1 to 8. Two-thirds of the abscess samples were positive for at least one of the target viruses. Specifically, the most frequently detected viruses were HHV-8 (54.5%); HPV (9%); and varicella zoster virus (VZV), Epstein-Barr virus (EBV), and HHV-6 (6%). Bacterial DNA was present in all cases and the most prevalent bacterial species were Treponema denticola (70%), Tannerella forsythia (67%), Porphyromonas endodontalis (67%), Dialister invisus (61%), and Dialister pneumosintes (57.5%). HHV-8 was positively associated with 7 of the target bacterial species and HPV with 4, but all these associations were weak. Several bacterial pairs showed a moderate positive association. Viral coinfection was found in 6 abscess cases, but no significant viral association could be determined. Findings demonstrated that bacterial and viral DNA occurred concomitantly in two-thirds of the samples from endodontic abscesses. Although this may suggest a role for viruses in the etiology of apical abscesses, the possibility also exists that the presence of viruses in abscess samples is merely a consequence of the bacterially induced disease process. Further studies are necessary to clarify the role of these viral-bacterial interactions, if any, in the pathogenesis of acute apical abscesses. Copyright © 2011 Mosby, Inc. All rights reserved.

Impact of Type III Secretion Effectors and of Phenoxyacetamide Inhibitors of Type III Secretion on Abscess Formation in a Mouse Model of Pseudomonas aeruginosa Infection

ABSTRACT Pseudomonas aeruginosa is a leading cause of intra-abdominal infections, wound infections, and community-acquired folliculitis, each of which may involve macro- or microabscess formation. The rising incidence of multidrug resistance among P. aeruginosa isolates has increased both the economic burden and the morbidity and mortality associated with P. aeruginosa disease and necessitates a search for novel therapeutics. Previous work from our group detailed novel phenoxyacetamide inhibitors that block type III secretion and injection into host cells in vitro. In this study, we used a mouse model of P. aeruginosa abscess formation to test the in vivo efficacy of these compounds against the P. aeruginosa type III secretion system (T3SS). Bacteria used the T3SS to intoxicate infiltrating neutrophils to establish abscesses. Despite this antagonism, sufficient numbers of functioning neutrophils remained for proper containment of the abscesses, as neutrophil depletion resulted in an increased abscess size, the formation of dermonecrotic lesions on the skin, and the dissemination of P. aeruginosa to internal organs. Consistent with the specificity of the T3SS-neutrophil interaction, P. aeruginosa bacteria lacking a functional T3SS were fully capable of causing abscesses in a neutropenic host. Phenoxyacetamide inhibitors attenuated abscess formation and aided in the immune clearance of the bacteria. Finally, a P. aeruginosa strain resistant to the phenoxyacetamide compound was fully capable of causing abscess formation even in the presence of the T3SS inhibitors. Together, our results further define the role of type III secretion in murine abscess formation and demonstrate the in vivo efficacy of phenoxyacetamide inhibitors in P. aeruginosa infection.

'Focal necrotizing pneumonia' was defined as a localized type of necrotizing pneumonia characterized by a single or few cavities of low density without rim enhancement on computed tomography (CT) scan. The purpose of this study was to investigate the clinical features and course of patients with focal necrotizing pneumonia, thereby elucidating its clinical relevance. The present study was conducted retrospectively in patients who had been interpreted as having lung abscess or necrotizing pneumonia on CT scan. Clinical and radiological characteristics were compared between the focal necrotizing pneumonia and lung abscess groups. Overall, 68 patients with focal necrotizing pneumonia (n = 35) or lung abscess (n = 33) were included in the present study. The frequency of risk factors for aspiration was significantly lower in the focal necrotizing group, compared with the lung abscess group (14.3% vs 45.5%, P = 0.005). Compared with lung abscess, focal necrotizing pneumonia was observed more commonly in non-gravity-dependent segments (66% vs 36%, P < 0.001). In addition, a trend towards more common isolation of aerobes as potential pathogens was observed in the focal necrotizing pneumonia group, compared with the lung abscess group (31% vs 12%, P = 0.08). However, in terms of treatment outcomes, a similar high rate of success was observed in both groups: 97%, respectively. Compared to lung abscess, focal necrotizing pneumonia occurs more commonly in non-gravity-dependent segments with lower incidence of risk factors for aspiration. Similar to lung abscess, the rate of success for treatment of focal necrotizing pneumonia was high. © 2013 The Authors. Respirology © 2013 Asian Pacific Society of Respirology.

Intratumoral lung abscess is a secondary lung abscess that is considered to be fatal. Therefore, surgical procedures, although high-risk, have sometimes been performed for intratumoral lung abscesses. However, no studies have examined the surgical outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. The aim of this study was to investigate the surgical and survival outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. Eleven consecutive non-small cell lung cancer patients with intratumoral lung abscesses, who had undergone pulmonary resection at our institution between January 2007 and December 2015, were retrospectively analysed. The post-operative prognoses were investigated and prognostic factors were evaluated. Ten of 11 patients were male and one patient was female. The median age was 64 (range, 52-80) years. Histopathologically, 4 patients had Stage IIA, 2 patients had Stage IIB, 2 patients had Stage IIIA, and 3 patients had Stage IV tumors. The median operative time was 346 min and the median amount of bleeding was 1327 mL. The post-operative morbidity and mortality rates were 63.6% and 0.0%, respectively. Recurrence of respiratory infections, including lung abscesses, was not observed in all patients. The median post-operative observation period was 16.1 (range, 1.3-114.5) months. The 5-year overall survival rate was 43.3%. No pre-operative, intra-operative, or post-operative prognostic factors were identified in the univariate analyses. Surgical procedures for advanced-stage non-small cell lung cancer patients with intratumoral lung abscesses, although high-risk, led to satisfactory post-operative mortality rates and acceptable prognoses.

To evaluate the presence or absence of periapical (PA) radiolucencies on individual roots of teeth with necrotic pulps, as assessed with digital PA radiographs and cone-beam computed tomography (CBCT). Digital PA radiographs and CBCT scans were taken from 161 endodontically untreated teeth (from 155 patients) diagnosed with non-vital pulps (pulp necrosis with normal PA tissue, symptomatic apical periodontitis, asymptomatic apical periodontitis, acute apical abscess and chronic apical abscess). Images were assessed by two calibrated endodontists to analyse the radiographic PA status of the teeth. A consensus was reached in the event of any disagreement. The data were analysed using a McNemar's test, and significance was set at P ≤ 0.05. Three hundred and forty paired images of roots were assessed with both digital PA radiographs and CBCT images. Fifteen additional roots were identified with CBCT. PA radiolucencies were present in 132 (38.8%) roots when assessed with PA radiographs, and in 196 (57.6%) roots when assessed with CBCT. This difference was statistically significant (P < 0.05). In teeth diagnosed with pulp necrosis, symptomatic apical periodontitis or acute apical abscess, CBCT images revealed a statistically larger number of PA radiolucencies than did PA radiographs (P < 0.05). No statistical differences were observed between PA radiographs and CBCT in teeth classified with asymptomatic apical periodontitis (P = 0.31) or chronic apical abscess (P = 1). Unlike PA radiographs, CBCT revealed a higher prevalence of PA radiolucencies when endodontically untreated teeth with non-vital pulps were examined. © 2013 International Endodontic Journal.

Intra-abdominal abscesses (IAA) are complications of Crohn's disease, which often result in hospitalization, surgery, and increased cost. Initial management may include medical therapy, percutaneous drainage (PD), or surgery, although the optimal management of IAA in children is unclear. Retrospective review of all pediatric patients with Crohn's disease who developed an IAA from January 1, 2000 to April 30, 2012. Three groups, based on initial IAA treatment modality (medical, PD, and surgery), were compared. Thirty cases of IAA were identified (mean age at IAA diagnosis, 15.4 ± 2.6 yr, 67% female, median Crohn's disease duration, 2.6 mo). Computed tomography was the most common initial (93%) and follow-up (47%) imaging. The average time to follow-up imaging was 8.5 days. For initial management, 18 received medical therapy, 10 PD, and 2 had surgery. The medical therapy group received more computed tomography scans for follow-up imaging than the PD group (12 [67%] versus 2 [20%], P = 0.046). There were no significant differences in abscess characteristics or management of posttreatment course between these 2 groups. Surgical resection occurred in 3 patients (17%) in the medical group and 2 (20%) in the PD group during index hospitalization. No significant differences were identified among treatment groups for readmissions, complications, or abscess recurrence. By 1 year, 12 of the 18 medically managed patients (67%) had surgery, and 6 of the 10 patients (60%) treated with initial PD ultimately had surgery. The majority of patients with IAA require definitive surgical treatment, and there were no clear predictors of those who did not.

Prostatic abscesses are an infrequent pathology, probably due to a better and early management of prostatic infections. Predisposing factors in this pathology are diabetes mellitus, urethral catheterism or manipulation, and immunodepressed states like AIDS. Nowadays, ultrasonography is an excellent diagnostic method of this pathology, and serves as a guidance of directed drainage. We present five cases in which the size of the abscess was determining in relation to the therapeutic attitude. Abscesses of less than 2 cm, measured by transrectal ultrasonography, can be evacuated by directed puncture, followed by antibiotic treatment. When the diameter of the abscess is greater than 2 cm, we realize a perineal drainage with a catheter placed with transrectal ultrasonography. Currently, TUR and other methods seems to be overcome.

In digitized radiography techniques, adjusting the image enhancement can improve the subjective image quality by optimizing the brightness and contrast for diagnostic needs. To determine the value range of image enhancement (brightness and contrast) on chronic apical abscess and apical granuloma interpretation. 30 periapical radiographs that diagnosed chronic apical abscess and 30 that diagnosed apical granuloma were adjusted by changing brightness and contrast values. The value range of brightness and contrast adjustment that can be tolerated in radiographic interpretations of chronic apical abscess and apical granuloma spans from -10 to +10. Brightness and contrast adjustments on digital radiographs do not affect the radiographic interpretation of chronic apical abscess and apical granuloma if conducted within the value range.

The diagnosis of lung abscess can be difficult to make and often requires imaging beyond plain chest x-ray. The decision to further image with computed tomography should be weighed against the risks of radiation exposure, especially in pediatric patients. In addition, the cost and potential impact on length of stay from obtaining computed tomography scans should be considered. In this report, we describe a case of lung abscess made immediately using point-of-care ultrasound in the emergency department. To our knowledge, there are no previous cases describing lung abscess diagnosed by point-of-care ultrasound. This case report aims to describe a case of pediatric lung abscess, review the ultrasound findings, and discuss relevant literature on the topic.

Pulmonary Abscess as a Complication of Transbronchial Lung Cryobiopsy.

We present the case of a 49-year-old man who developed pulmonary abscess as a complication of transbronchial lung cryobiopsy. He had been receiving prednisone therapy, but otherwise had no specific risk factors for lung abscess. Cryobiopsy is a novel technique for obtaining peripheral lung parenchymal tissue for the evaluation of diffuse parenchymal lung diseases. Cryobiopsy is being increasingly proposed as an alternative to surgical lung biopsy or conventional bronchoscopic transbronchial forceps biopsy, but the safety profile of the procedure has not been fully appreciated. Pulmonary abscess has been rarely reported as a complication of other bronchoscopic procedures such as endobronchial ultrasound-guided needle biopsy, however, to our knowledge this is the first reported case of pulmonary abscess complicating peripheral lung cryobiopsy.

Approximately 20% of patients develop some complications after gastrectomy. These complications should be treated appropriately to achieve a positive outcome. The records of 6 patients with postoperative intra-abdominal abscesses treated with interventional radiology (IVR) were analyzed. The cause of abscess was anastomotic leakage in 4 patients and contaminated surgery after gastric perforation in 2 patients. Intra-abdominal abscesses were detected on postoperative day 12 (median), and an IVR-guided drainage tube was inserted with a median interval of 1 day. The drainage tube was kept in place for 26 days (median), and patients were discharged 6.5 days (median) after drainage tube removal. No patients were converted to open surgery. Early IVR-guided drainage was essential and effective for intra-abdominal abscess treatment after gastrectomy.

The use of the fiberoptic bronchoscope as a drainage procedure for lung abscess has become more and more widespread. We have recently adopted the technique of inserting a simple polyethylene catheter through the flexible fiberoptic bronchoscope into the abscess cavity of 11 patients with lung absess. All cases had not responded to aggressive postural drainage and adequate antibiotic therapy for at least a week. The results were as follows: Among 11 patients, the therapeutic response was dramatic in 6 patients.In the successful group, the abscess sizes were greater than 8cm in diameter and the air-fluid levels were higher than two-thirds of the cavity.Additional diagnoses, other than bacterial lung abscess, could be made in 2 cases when otherwise the diagnosis would have remained in doubt. The authors suggest that catheter drainage via fiberoptic bronchoscpope is an effective treatment modality in the large lung abscess with a high air-fluid level which is intractable to other medical approaches, and it is also a safe procedure.
