  1. Excessive Surgical Adhesive Mimicking Aortic Root Abscess: A Case Report.

    Silverton, Natalie A; Bull, David A; Morrissey, Candice K


    Aortic root abscess is a complication of aortic valve endocarditis that is associated with a high morbidity and mortality. The diagnosis usually is made with transesophageal echocardiography, which is highly sensitive and specific for the disease. We present a case of suspected aortic root abscess 1 week after mechanical aortic valve replacement for native valve endocarditis. The diagnosis was made by the use of transesophageal echocardiography but surgical inspection revealed that the paravalvular fluid collection was excessive surgical adhesive. We discuss the clinical significance and differential diagnosis of aortic root abscess in the setting of infective endocarditis.

    Guo Huijie; Gao Chengzhi; Zhang Chengfei; Zheng Shuying; Yue Lin


    Background Apical abscess is an inflammatory process in the peri-radicular tissues caused by biofllms in the necrotic root canal systems.Therefore,a comprehensive analysis of the bacterial colonization is required for a better understanding of the pathogenesis.This study aimed to investigate the patterns of bacterial infection of root canals of teeth with apical abscesses and to determine whether histological and microbiological findings correlated with clinical conditions.Methods Eighteen samples from 18 teeth with apical pathological lesions were analyzed.Nine patients with acute apical abscesses experienced severe pain,and nine patients were asymptomatic with a sinus tract.After extraction,each affected root was divided into two halves.One half was processed for histobacteriologic analysis and examined using light microscopy,and the other half was analyzed using scanning electron microscopy (SEM) to determine the patterns of microbial colonization of the root canals.Results The appearance of each sample subjected to SEM was consistent with the histobacteriologic findings despite the presence or absence of clinical symptoms.Intraradicular biofilms comprising cocci,rods,and/or filaments of amorphous materials were observed in the apical third of the main root canals in all samples.The bacterial biofilms covering the main root canal walls also penetrated the dentinal tubules to varying depths.The morphologies of biofilms varied,and a unique pattern of intraradicular infection was not identified.Conclusion Intraradicular infections formed complex and variable multispecies biofilms and their presence did not correlate with clinical symptoms.

  6. Spinal epidural abscess as a result of dissemination from gluteal abscess secondary to intramuscular analgesic injection.

    Sasani, Mehdi; Aydin, Ozlem; Aydin, Ahmet Levent; Oktenoglu, Tunc; Ozer, Ali Fahir; Ercelen, Omur


    Spinal epidural abscess is a collection of suppurative material that forms between the dura mater and the ligamentum flavum. If not recognized early and treated correctly, it can lead to life-threatening sepsis. Here we report the case of a female patient, 51 years of age, with difficulty walking and bilateral leg pain after having had degenerative discogenic pain for many years. The patient had occasionally received intramuscular non-steroidal anti-inflammatory drug injections. The current report is that of an unusual case of epidural abscess that formed following multiple dose of intramuscular non-steroidal anti-inflammatory drug over a 1-year period. Hematogenous or direct dissemination is the suspected cause. To prevent serious morbidity and mortality, early diagnosis is essential. Patients with localized back pain who are at risk for developing such epidural spinal abscesses should receive a magnetic resonance imaging scan with contrast enhancement without delay. The existence of predisposing factors such as intramuscular injections should be considered in the assessment of suspected spinal epidural abscess.

  8. Corneoscleral abscess resulting from a broken suture after cataract surgery.

    Cameron, J A; Huaman, A


    An 82-year-old man had pain and decreased vision in his right eye 15 months after uncomplicated cataract surgery. Examination revealed a large corneoscleral abscess with a 2 mm x 1 mm area of fluorescein staining at the base of a broken protruding 10-0 nylon suture. Streptococcus pneumoniae was isolated from both the suture and base of the ulcer. Despite intensive topical, subconjunctival, and systemic antibiotics, a large corneal perforation developed, necessitating a 10 mm tectonic penetrating keratoplasty. Long-term follow-up of patients after cataract surgery is important and should include an inspection of the limbal wound and removal of loose or broken exposed sutures. Suture-related complications will be eliminated if clinical studies prove the safety and efficacy of sutureless cataract surgery.

  9. CT-guided percutaneous drainage of intra-abdominal abscesses: APACHE III score stratification of 1-year results

    Betsch, Angelika; Belka, Claus [Department of Radiation Oncology, Eberhard Karls University, Hoppe-Seyler-Strasse 3, 72076 Tuebingen (Germany); Wiskirchen, Jakub; Truebenbach, Jochen; Claussen, Claus D.; Duda, Stephan H. [Department of Diagnostic Radiology, Eberhard Karls University, Hoppe-Seyler-Strasse 3, 72076 Tuebingen (Germany); Manncke, Klaus H. [Department of General Surgery, Eberhard Karls University, Hoppe-Seyler-Strasse 3, 72076 Tuebingen (Germany)


    Our objective was to evaluate the clinical success rates of percutaneously drained intra-abdominal abscesses using a risk stratification score for severely ill patients (APACHE III; Acute Physiology, Age, Chronic Health Evaluation). In 75 patients CT-guided percutaneous abscess drainage was performed to treat intra-abdominal abscesses. The clinical success rate based on a 1-year follow-up was correlated with abscess etiology, size, and structure, as well as with the initial APACHE III score. Clinical success, i.e., the complete removal of the abscess without surgical treatment, was observed in 62 of 75 patients (83%). Abscess size (<200 cm{sup 3}) and abscesses with a simple structure correlated with higher clinical success rates. Patients presenting with APACHE III scores below 30 were treated by percutaneous abscess drainages (PAD) alone significantly more often than patients presenting with higher APACHE scores. The percutaneous drainage of intra-abdominal abscesses shows good long-term results as long as abscesses are singular, small (<200 cm{sup 3}), and located in well accessible regions in combination with low APACHE scores (<30).

  10. Acute abscess with fistula: long-term results justify drainage and fistulotomy.

    Benjelloun, E B; Jarrar, A; El Rhazi, K; Souiki, T; Ousadden, A; Ait Taleb, K


    Conventional treatment of anal abscess by a simple drainage continues to be routine in many centers despite retrospective and randomized data showing that primary fistulotomy at the time of abscess drainage is safe and efficient. The purpose of this study is to report the long-term results of fistulotomy in the treatment of anal abscesses. This is a prospective nonrandomized study of 165 consecutive patients treated for anal abscess in University Hospital Hassan II, Fez, Morocco, between January 2005 and December 2010. Altogether 102 patients were eligible to be included in the study. Among them, 52 were treated by a simple drainage and 50 by drainage with fistulotomy. The results were analyzed in terms of recurrence and incontinence after a median follow-up of 3.2 years (range 2-6 years). The groups were comparable in terms of age, gender distribution, type and size of abscess. The recurrence rate after surgery was significantly higher in the group treated by drainage alone (88 %) compared to other group treated by drainage and fistulotomy (4, 8 %) (p fistulotomy group (5 % vs 1 %), although this difference was not significant (p = 0.27). In the group treated by drainage and fistulotomy, high fistula tract patients are more prone to develop incontinence and recurrence, mainly within the first year. A long-term follow-up seems not to influence the results of fistulotomy group. These findings confirm that fistulotomy is an efficient and safe treatment of anal abscess with good long-term results. An exception is a high fistula, where fistulotomy may be associated with a risk of recurrence and incontinence.

  11. Ultrasound-guided endocavitary drainage of pelvic abscesses: Technique, results and complications

    Ryan, R.S.; McGrath, F P.; Haslam, P.J.; Varghese, J.C.; Lee, M.J


    AIM: To evaluate the experience in our institution with ultrasound-guided transrectal and transvaginal (endocavitary) drainage of pelvic abscesses. MATERIALS AND METHODS: Eighteen patients (four male, 14 female; mean age 55 years, range 30-78 years) presenting with pelvic abscesses were referred to our institution for therapeutic drainage over a 4 year period. Patients received broad-spectrum antibiotics prior to drainage, which was performed by either the transvaginal or transrectal route under ultrasound guidance. Patients were given sedo-analgesia in the form of midazolam and fentanyl and local anaesthesia was also employed. Eight French catheters were inserted into the abscess cavities, and patients were subsequently monitored on a daily basis by a member of the interventional radiology team until such time as it was deemed appropriate to remove the catheter. RESULTS: Eighteen catheters were placed in 17 patients, and transvaginal aspiration alone was performed in one patient. Drainage was successful in 16 of 17 patients, but a transgluteal approach was ultimately required in the remaining patient to enable passage of a larger catheter into an infected haematoma. The mean duration of drainage was 5 days, mean time to defervesce 2 days. Spontaneous catheter dislodgement occurred in four patients associated with straining, but this did not have any adverse effect in three of the four patients. CONCLUSION: Endocavitary drainage is an effective method of treatment for pelvic abscesses. Spontaneous catheter dislodgement does not affect patient outcome.

  12. Microbiology and Treatment of Acute Apical Abscesses

    Rôças, Isabela N.


    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.

  14. Endovascular aortic graft infection resulting in retroperitoneal abscess: report of a case

    Salvatore Di Somma


    Full Text Available Infection is a rare complication of aortoiliac endovascular procedures, with an incidence inferior to 0.5%, and it may result in a retroperitoneal abscess potentially evolving to sepsis and gastrointestinal bleeding. In more than 50% of cases endovascular aortoiliac prosthetic grafts infection occur months or years after the procedure. The growing number of endovascular procedures, and as the actually midterm follow up in most cases, septic sequelae will no doubt continue to occur with increased frequency and may represent an emerging problem in the ED for the emergency physician. Endovascular graft infection begins with unspecific clinical manifestations. An high index of suspicion in any patient with an aortic stent graft presenting prolonged or recurrent fever and or abdominal or back pain and a low threshold for obtaining CT scan should increase the clinician’s ability to make a timely diagnosis in the ED setting.

  15. Primary Intraventricular Brain Abscess Resulting in Isolated Dilation of the Inferior Horn and Unilateral Hydrocephalus

    Joji Inamasu


    Full Text Available Primary intraventricular brain abscesses are rare, and there are no established treatment guidelines for this condition. We report a case in which isolated ventricular dilatation and unilateral hydrocephalus developed after seemingly successful conservative management and which required surgical diversion of the cerebrospinal fluid. A 59-year-old woman presented to our emergency department with high-grade fever and headache. Brain magnetic resonance imaging (MRI revealed abscesses in the bilateral posterior horn. Although surgical evacuation of the abscesses was considered, conservative management with antibiotics was selected because of the paucity of severe neurological deficits and the concern that an attempt to evacuate the intraventricular abscess might lead to inadvertent rupture of the abscess capsule and acute ventriculitis. Despite reduction in the abscess volume, the patient developed an altered mental status 4 weeks after admission. Follow-up MRI revealed isolated dilation of the left inferior horn, compressing the brainstem. Emergency fenestration of the dilated inferior horn was performed, and endoscopic observation revealed an encapsulated abscess with adhesion to the ventricular wall which was thought responsible for the ventricular dilation and unilateral hydrocephalus. Two weeks after the initial surgery, the unilateral hydrocephalus was treated by placement of a ventriculoperitoneal shunt. Eradication of the intraventricular brain abscesses without surgical evacuation may justify the conservative management of this patient. However, the possibility that earlier surgical evacuation might have prevented development of the isolated ventricular dilation cannot be denied. Additional clinical experience is required to determine which treatment (surgical vs. conservative is more appropriate in patients with primary intraventricular brain abscesses.

  16. Biostatistical analysis of treatment results of bacterial liver abscesses using minimally invasive techniques and open surgery

    Кipshidze A.A.


    Full Text Available Today bacterial abscesses remain one of the most difficult complications in surgical hepatology, both traditional and minimally invasive methods of their treatment are used. Bio-statistical analysis is used due to the fact that strong evidences are required for the effectiveness of one or another method of surgical intervention. The estimation of statistical significance of differences between the control and the main group of patients with liver abscesses is given in this paper. Depending on the treatment method patients were divided into two groups: 1 - minimally invasive surgery (89 cases; 2 – laporatomy surgery (74 patients. Data compa¬ri¬son was performed by means of Stjudent's criterion. The effectiveness of method of abscesses drainage using inter¬ventional sonography, outer nazobiliar drainage with reorganization of ductal liver system and abscess cavity with the help of modern antiseptics was considered. The percentage of cured patients was also estimated.

  17. [Cerebellar abscesses secondary to infection of an occipital dermal sinus].

    García Galera, A; Martínez León, M I; Pérez da Rosa, S; Ros López, B


    A dermal sinus is a congenital defect arising from a closure failure of the neural tube that results in different degrees of communication between the skin and the central nervous system. A dermal sinus can occur anywhere from the root of the nose to the conus medullaris, and the occipital location is the second most common. Dermal sinuses are often found in association with dermoid or epidermoid cysts and less frequently with teratomas. Patients with an occipital dermoid cyst associated with a dermal sinus can develop meningitis and/or abscesses as the first clinical manifestation of the disease due to the dermoid cyst itself becoming abscessed or to the formation of secondary abscesses; few cases of the formation of secondary abscesses have been reported. We present a case of a dermoid cyst associated with an infected dermal sinus and posterior development of cerebellar abscesses and hydrocephalus.

  18. Treatment of localized abscesses induced by methicillin-resistant Staphylococcus aureus (MRSA) using MRgFUS: First in vivo results

    Rieck, Birgit; Curiel, Laura; Mougenot, Charles; Zhang, Kunyan; Pichardo, Samuel


    Background. In the present work we study the therapeutic effect of focused ultrasound on localized abscess induced by methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a major nosocomial pathogen in health-care facilities. The people, particularly those who are immunocompromised are prone to develop infectious sites that often are non-responsive to regular treatments. Because of its capability to induce a rise of temperature at a very precise location, the use of focused ultrasound represents a considerable opportunity to propose a new therapy for MRSA-related infections. Methods. A 50μL subcutaneous injection of MRSA strain USA 400 bacteria at a concentration of 7×103/μL was made on the left thigh of BALB/c mice and an abscess of 6±2 mm-length formed after 48hrs. A transducer operating at 3 MHz with a focal length of 50mm and diameter of 32mm was used to treat the abscess. The focal point was positioned 2mm under the skin at the abscess center. Forty-eight hours after injection 4 ultrasound exposures of 9s-each were applied to each abscess under Magnetic Resonance-guidance. Each exposure was followed by a 1 min pause. Real-time estimation of change of temperature was done using a communication toolbox (matMRI) developed in our laboratory. Three experimental groups of 6 animals each were tested: moderate temperature (MT), high temperature (HT) and control. MT and HT groups reached, respectively, 55°C and 65°C at end of exposure. Effectiveness of the treatment was assessed by culturing bacteria of the treated abscess 1 and 4 days after treatment. Spleen samples were cultured to test for septicemia. Results. Macroscopic evaluation of treated abscess indicated a diminution of external size of abscess 1d after treatment. Treatment did not cause open wounds. Bacteria counting 1 day after treatment was 0.7±1.1 × 105, 0.5±0.7 × 105 and 1.1±2.3 × 105 CFU/μl for MT, HT and control groups, respectively; for the 4-day end point, the count was 0.6±0.6

  19. Quantification of endotoxins in infected root canals and acute apical abscess exudates: monitoring the effectiveness of root canal procedures in the reduction of endotoxins.

    Sousa, Ezilmara L R; Martinho, Frederico C; Nascimento, Gustavo G; Leite, Fabio R M; Gomes, Brenda P F A


    This clinical study was conducted to measure the endotoxin levels in infected root canals (RCs) and exudates related to acute apical abscesses (AAAs). In addition, the effectiveness of RC procedures in reducing the endotoxin levels in RCs was monitored. Paired samples of infected RCs and exudates from AAAs were collected from 10 subjects by using paper points. RCs samples were collected before (RCS1) and after chemomechanical preparation (CMP) (RCS2), after 17% EDTA (RCS3), and after 30 days of intracanal medication (Ca[OH]2 + chlorhexidine) (RCS4). A turbidimetric kinetic limulus amebocyte lysate assay was used for the measurement of endotoxins. Endotoxins were detected in 100% of the baseline samples of AAAs and RCs (RCS1) with median values of 175 EU/mL and 41.5 EU/mL, respectively (P < .05). After CMP (RCS2), endotoxins were reduced to a median value of 0.54 EU/mL (P < .05). Subsequent irrigation with EDTA (RCS3) failed to present a significant effectiveness in reducing the endotoxin levels (median= 0.37 EU/mL) (P = .07). However, intracanal medication for 30 days (RCS4) reduced endotoxins to median values of 0.03 EU/mL (P < .01). The present study revealed a strong association between the high levels of endotoxins found in AAAs and RCs collected from the same tooth. Moreover, the effectiveness of CMP in reducing the endotoxin levels from RCs in acute endodontic infection was improved by the use of RC medication.

  20. Intramedullary abscess resulting from disseminated cryptococcosis despite immune restoration in a patient with AIDS.

    Rambeloarisoa, J; Batisse, D; Thiebaut, J-B; Mikol, J; Mrejen, S; Karmochkine, M; Kazatchkine, M D; Weiss, L; Piketty, C


    We report on a case of cryptococcal intramedullary abscess, which occurred three years after a disseminated cryptococcosis and two years after a lymph node cryptococcal recurrence in a HIV-infected patient who exhibited a long-standing immune restoration. At the time of diagnosis, CD4(+) lymphocyte-count was 640x10(6)/l and HIV viral load was undetectable. Spinal involvement is rare during cryptococcosis of the central nervous system. As far as we are aware, there is only one case of proven intramedullary cryptococcal abscess reported in the literature and this case is then the second one. The significant and sustained increase in CD4 count following effective antiretroviral therapy was probably associated with only a partial immune restitution that did not allow to avoid the occurrence of the cryptococcal medullar abscess. Finally, this case raises the question of when to stop secondary prophylaxis of cryptococcal disease after increase in CD4 cell count under antiretroviral therapy.

  1. Retroperitoneal Abscess Formation as a Result of Spilled Gallstones during Laparoscopic Cholecystectomy: An Unusual Case Report

    Grigoris Chatzimavroudis


    Full Text Available One of the complications of laparoscopic cholecystectomy for gallstone disease that seems to exceed that of the traditional open method is the gallbladder perforation and gallstone spillage. Its incidence can occur in up to 40% of patients, and in most cases its course is uneventful. However in few cases an abdominal abscess can develop, which may lead to significant morbidity. Rarely an abscess formation due to spilled and lost gallstones may occur in the retroperitoneal space. We herein report the case of a female patient who presented with clinical symptoms of sepsis six months following laparoscopic cholecystectomy. Imaging investigations revealed the presence of a retroperitoneal abscess due to retained gallstones. Due to patient’s decision to refuse abscess’s surgical drainage, she underwent CT-guided drainage. The 24-month followup of the patient has been uneventful, and the patient remains in good general condition.

  2. Invasive group A Streptococcus resulting in sepsis and abdominal wall abscess after adenotonsillectomy.

    Wilson, Paul F; Wannemuehler, Todd J; Matt, Bruce H


    Systemic infectious complications following adenotonsillectomy are exceedingly rare. We describe an otherwise healthy 2-year-old patient who developed group A beta-hemolytic Streptococcus sepsis and presumptive scarlet fever 3 days after an uncomplicated adenotonsillectomy. After resolution of fever, rash, and discharge home on antibiotics, the patient returned on postoperative day 10 with an abdominal wall abscess. This is the first reported case of an abdominal wall abscess as a complication of adenotonsillectomy. This case demonstrates that an awareness of unexpected infectious complications of adenotonsillectomy should be a part of postsurgical management. Laryngoscope, 125:1230-1232, 2015.

  5. Tractography of lumbar nerve roots: initial results

    Balbi, Vincent; Budzik, Jean-Francois; Thuc, Vianney le; Cotten, Anne [Hopital Roger Salengro, Service de Radiologie et d' Imagerie musculo-squelettique, Lille Cedex (France); Duhamel, Alain [Universite de Lille 2, UDSL, Lille (France); Bera-Louville, Anne [Service de Rhumatologie, Hopital Roger Salengro, Lille (France)


    The aims of this preliminary study were to demonstrate the feasibility of in vivo diffusion tensor imaging (DTI) and fibre tracking (FT) of the lumbar nerve roots, and to assess potential differences in the DTI parameters of the lumbar nerves between healthy volunteers and patients suffering from disc herniation. Nineteen patients with unilateral sciatica related to posterolateral or foraminal disc herniation and 19 healthy volunteers were enrolled in this study. DTI with tractography of the L5 or S1 nerves was performed. Mean fractional anisotropy (FA) and mean diffusivity (MD) values were calculated from tractography images. FA and MD values could be obtained from DTI-FT images in all controls and patients. The mean FA value of the compressed lumbar nerve roots was significantly lower than the FA of the contralateral nerve roots (p=0.0001) and of the nerve roots of volunteers (p=0.0001). MD was significantly higher in compressed nerve roots than in the contralateral nerve root (p=0.0002) and in the nerve roots of volunteers (p=0.04). DTI with tractography of the lumbar nerves is possible. Significant changes in diffusion parameters were found in the compressed lumbar nerves. (orig.)

  6. Single step therapy for abscess foci localized at different parts of the body using trocar type catheter: Results of two year-experience

    Orhan Özbek


    Full Text Available Objectives: The aim of this study was to emphasize the feasibility and cost effectiveness of trocar type catheter in percutaneous abscess drainage under imaging guidance and to determine the clinical efficacy of the method.Materials and methods: From June 2008 to December 2010, 48 patients who were referred to interventional radiology unit, in order to undergo percutaneous abscess drainage. All was data including age, the organ or the part of the body where the abscess was localized and size of abscess were recorded. Forty-two (87% patients underwent drainage with ultrasonographic guidance, while 6 (13% underwent with computed tomography guidance. One pediatric patient underwent systemic sedation anesthesia (with remiphentanyl and midazolam and the rest of the patient with local anesthesia (with prilocain hydrochlorid. Catheterization procedure with which abscess drainage was done accepted as technically successful.Results: Imaging guided percutaneous abscess drainage procedures were performed with trocar type catheter to localized abscesses in different organs or systems in 48 patients (25 men, 23 women, mean age 52 years, range 2-82 years. Technical success was 100% in all cases. No patient had a complication during the procedure. Time to extraction of percutaneous catheter after drainage procedure was 5-28 days (mean 11.2 days. There was no recurrence except for a case, in which an abscess at the splenectomy site was successfully drained.Conclusion: Percutaneous drainage with imaging guidance using the trocar type catheter should be preferred because of its feasibility, cost-effectiveness, and reduced rate of complications in treating abscesses, which localized at different organ systems.

  7. Fusobacterium Liver Abscess

    Ben D. Buelow


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

  8. Brodie's abscess revisited.

    Kornaat, P R; Camerlinck, M; Vanhoenacker, F M; De Praeter, G; Kroon, H M


    Radiology plays an important role in the diagnosis of a Brodie's abscess, as can be difficult for a clinician to identify the disease using clinical information alone. A Brodie's abscess is clinically difficult to diagnose because patients typically have mild local symptoms, few or no constitutional symptoms, and near normal laboratory values. Furthermore, a Brodie's abscess may mimic various benign and malignant conditions, resulting in delayed diagnosis and treatment. The most frequently made incorrect diagnosis is that of a primary bone tumor. The present pictorial review summarizes imaging clues to the diagnosis of a Brodie's abscess, such as the serpentine sign on conventional radiographs and the penumbra sign seen on Magnetic Resonance (MR) images. A Brodie's abscess is difficult to diagnose, however, once diagnosed, it is a curable disease with a 100% cure rate.

  9. [Brodie's abscess].

    Lindsetmo, R O; Due, J; Singh, K; Stalsberg, H


    Brodie's abscess is a localized subacute or chronic osteomyelitis independent of any known previous acute infection. The entity is often mistaken for a bone tumour. The diagnosis requires biopsy. The treatment is curettage, drainage and antibiotics for a minimum of six weeks. We describe the characteristics of Brodie's abscess and describe a patient with an illustrating history, but with an unusual localization of the abscess (osilium).

  10. Aspergillus spinal epidural abscess

    Byrd, B.F. III (Vanderbilt Univ. School of Medicine, Nashville, TN); Weiner, M.H.; McGee, Z.A.


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

  11. Spontaneous spinal epidural abscess.

    Ellanti, P


    Spinal epidural abscess is an uncommon entity, the frequency of which is increasing. They occur spontaneously or as a complication of intervention. The classical triad of fever, back pain and neurological symptoms are not always present. High index of suspicion is key to diagnosis. Any delay in diagnosis and treatment can have significant neurological consequences. We present the case of a previously well man with a one month history of back pain resulting from an epidural abscess.

  12. Gravisensing in flax roots - results from STS-107

    Hasenstein, K. H.; Scherp, P.; Ma, Z.

    The goal of the experiment "magnetophoretic induction of curvature in roots" (MICRO) on STS-107 was the induction of curvature in roots by high-gradient magnetic fields (HGMF) in microgravity. The scientific objectives included investigating the growth/curvature pattern in response to a HGMF, the determination of amyloplasts as gravisensing/curvature-inducing structures, and a study of the effects of HGMF and microgravity on the plant cytoskeleton. Flax seeds were germinated in orbit in specially designed seed cassettes. The seeds were oriented so that the emerging roots grew away from the cassette. The magnetic system consisted of ferro-magnetic wedges, magnetized by permanent NdFeB magnets (coercivity > 32k Oe). The HGMF that results from the transition from the high magnetic field density at the wedge tips to air repels diamagnetic amyloplasts. As a result of the previously demonstrated internal displacement of the amyloplasts, the roots were expected to curve as if gravistimulated. Despite successful germination (>90%), the growth rate of the seedlings was significantly lower than comparable controls. Despite the slower growth rate, root curvature was enhanced and initiated earlier than in ground controls. The results indicate that microgravity-grown roots exhibit higher sensitivity for the HGMF than ground controls. The enhanced sensitivity of root curvature in microgravity suggests that the root gravisensing system responds to the displacement of amyloplasts.

  15. Splenic abscesses.

    Al-Hajjar, Nadim; Graur, Florin; Hassan, Aboul B; Molnár, Geza


    Splenic abscesses are rare entities (autopsy incidence between 0.14-0.7%). The most frequent etiology is the septic emboli seeding from bacterial endocarditis (about 20% of cases) or other septic foci (typhoid fever, malaria, urinary tract infections, osteomielitis, otitis). The treatment of splenic abscesses was until recently splenectomy with antibiotherapy. The actual trends are more conservative (mini invasive or non-invasive) because the immunologic role of the spleen has been better understood over the last year

  18. Wandering Fish Bone: a Case of Pelvic Abscess due to Rectum Perforation Resulting from an Accidental Fish Bone Ingestion

    Sirous Abbasi


    Full Text Available Fish bone is the most common foreign body that is ingested accidentally and can be caused gastrointestinal complications such as perforation, abstraction, and abscess. We describe a 75-year-old man who suffered from constipation, diarrhea, and fever and chills for 3 months. He had mild tenderness in hypogasteric region and also mild tenderness and swelling on anterior rectal wall and prostate upon clinical examination. The abdominal and pelvic sonography and CT scan findings suggested existence of abscess in the space of between bladder and rectum. The patient underwent laparotomy to drainage the pelvic abscess. The surgeon found a 6-cm fish bone which was embedded in the abscess. The presented case indicated the importance of accidental fish bone ingestion and its possible complications. In addition, the patients with abdominal pain, GI bleeding, and fever of unknown origin living in the seaside regions, the wandering fish bone as a differential diagnosis should be kept in mind.

  19. Infective Endocarditis and Aortic Valve Abscess in an Infant.

    Williamson, Kristy A; Gmuca, Sabrina; Rosman, Eliyahu C; Thomas, Philomena


    Infective endocarditis is relatively uncommon in the pediatric population, but when it does occur, results in substantial morbidity and mortality. Children at risk for endocarditis are typically those with an underlying congenital heart condition. Furthermore, an endocardial abscess is a very rare yet serious complication of infective endocarditis. We describe a case of a 23-month-old previously healthy male infant with no known congenital heart disease who returned to the emergency department after a recent hospitalization for pneumococcal bacteremia, presenting acutely ill but without fever. He was found to be in congestive heart failure due to endocarditis and an aortic root abscess.

    ZOU Li-guang; CHEN Ken; LI Yan-yu; YI Xi-zhi


    Objective: To investigate the features of hepatic abscess by dynamic contrast-enhanced CT. Methods: CT films of 62 cases of hepatic abscesses were reviewed retrospectively. All the patients underwent both plain and enhanced CT scanning, and 23 of them received dynamic CT examination. Results: The dynamic phase (60~90 s), the enhancement patterns of the abscesses varied from the ring enhancement of the abscess diminished in which the hypodense ring enhanced and became isodense, or the abscess enhanced diffusely and became smaller, the colliquative necrosis area more obvious. Conclusion: Contrast enhanced CT should be used routinely in the evaluation of hepatic abscesses. The dynamic and delayed scan is necessary to diagnose atypical hepatic abscesses.

  7. Serratia marcescens spinal epidural abscess formation following acupuncture.

    Yang, Chih-Wei; Hsu, Shun-Neng; Liu, Jhih-Syuan; Hueng, Dueng-Yuan


    The formation of spinal epidural abscess following acupuncture is very rare. We herein report the case of a 54-year-old woman who presented with progressive low back pain and fever with a root sign. She underwent surgical decompression, with an immediate improvement of the low back pain. A culture of the epidural abscess grew Serratia marcescens. One year postoperatively, magnetic resonance imaging revealed the almost complete eradication of the abscess. This case is the first case of Serratia marcescens-associated spinal epidural abscess formation secondary to acupuncture. The characteristics of spinal epidural abscess that develop after acupuncture and how to prevent such complications are also discussed.

  8. CT of pituitary abscess

    Fong, T.C.; Johns, R.D.; Long, M.; Myles, S.T.


    Pituitary abscess is a rare condition, with only 50 cases reported in the literature. Of those, 29 cases were well documented for analysis. Preoperative diagnosis of pituitary abscess is difficult. The computed tomographic (CT) appearance of pituitary abscess was first described in 1983; the abscess was depicted by axial images with coronal reconstruction. The authors recently encountered a case of pituitary abscess documented by direct coronal CT of the sella turcica.

  9. Endoscopic management of brain abscesses

    Yadav Yad


    Full Text Available Background: Treatment of brain abscess is still a subject of controversy. Simple therapeutic approaches like twist drill/burr hole aspiration with or without insertion of a drain are also quite effective. There are reports of encouraging results following endoscopic treatment. We are reporting our results of endoscopic approach on 24 patients. Materials and Methods: This is a prospective study on 24 patients of brain abscesses treated between January 2004 and January 2007. All the cases except those with small abscesses (less than 1.0 cm in diameter and multiloculated abscesses were included. Gabb 6-degree rigid endoscope was used. Repeat CT scan was done in all cases within 7 and 30 days after surgery. Ten patients (42% had small residual abscess on 7 th post-operative day′s CT scan, while 30 th post-operative day′s CT scan did not show any significant lesion in all the cases. Results: There were 23 patients of chronic otitis media and one of congenital cyanotic heart disease. Glasgow coma score (GCS was 3 in one patient, 13 in two cases, 14-15 in 21 cases. There were 14 cerebellar, 8 temporal and 1 frontal and thalamic abscess each. All the patients recovered completely except one who died (GCS 3. There was no procedure-related complication. Hospital stay ranged from 7 to 12 days with an average of 8.2 days. Follow-up ranged between 6 and 42 months. Conclusion: Endoscopic aspiration of brain abscess appears to be a safe and effective alternative method of treatment. There is direct visualization of abscess cavity, completeness of aspiration can be assessed, and perioperative bleeding can be controlled.

  10. Perianal abscesses due to ingested foreign bodies

    Doublali Mbarek


    Full Text Available The clinical presentation of perianal abscesses due to foreign bodies (FBs impacted in the anal canal mimics common causes of acute anal pain. The diagnosis can be established by digital rectal examination and/or proctoscopy, but may miss the presence of an FB. Incision and drainage of the abscess, along with removal of the FB, results in immediate pain relief and cure. Impacted FB must not be overlooked as an unusual cause of perianal abscess. One case of perianal abscesses due to FB impacted in the anal canal is reported.

  14. Hepatocellular Carcinoma Mimicking Liver Abscesses in a Cirrhotic Patient with Severe Septic Shock as a Result of Salmonella O9 HG Infection

    Shuichi Hagiwara


    Full Text Available We describe a case of severe Salmonella O9 HG sepsis with a mass in the liver, which was diagnosed as hepatocellular carcinoma (HCC by autopsy of the liver. The patient was a 67-year-old man with chronic high blood pressure. In addition, he was an alcoholic and had been drinking every day for many years. He had had a dinner of ‘sukiyaki’ with a raw egg two days before admission. The next morning, he had developed vomiting, diarrhea, and abdominal pain. Salmonella O9 HG was found in the blood and stool cultures. In the computed tomography (CT finding of the liver, there was a 2 cm early-enhanced mass with a multilocular structure, with ringed enhancement and daughter nodes. Since we thought that the mass was a liver abscess, we performed needle aspiration from the liver mass and were able to withdraw blood. Despite adequate antibiotic treatment, the patient died as a result of complications on the 55th day after admission. After the patient’s death, we conducted an autopsy. There were two HCC masses, a moderately-differentiated and a well-differentiated mass, as a result of alcoholic cirrhosis of the liver. As the HCC had multilocular cyst-like structures, which were fiber- and necrosis-rich, CT images of the liver masses resembled abscesses.

    We review the literature to the diagnosis and therapeutic aspect of prostatic abscess. The prostatic abscess having become an uncommon disease. The diagnosis of prostatic abscess has been nearly made by transrectal ultrasound and computed tomography scan. The best diagnostic method is considered to be the transrectal ultrasound. The choice therapy was intravenous antibiotic, and drainage by ultrasound guided transperineal percutaneous puncture.

  17. Symmetrical Brodie's abscess.

    Chambler, A F; Chapman-Sheath, P J; Pearse, M F; Hollingdale, J


    Chronic recurrent multifocal osteomyelitis is often confused with symmetrical Brodie's abscess as it has a similar pathogenesis. We report an otherwise healthy 17-year-old boy presenting with a true symmetrical Brodie's abscess. We conclude that a symmetrical Brodie's abscess presenting in an otherwise healthy patient is a separate clinical condition with a different management protocol.

  4. Pyogenic brain abscess, a 15 year survey

    Helweg-Larsen Jannik


    Full Text Available Abstract 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.

  7. Magnesium Deficiency Results in Increased Suberization in Endodermis and Hypodermis of Corn Roots 1

    Pozuelo, José M.; Espelie, Karl E.; Kolattukudy, P. E.


    The composition of the aliphatic components of suberin in the stele and cortex of young corn (Zea mays L.) roots was determined by combined gas-liquid chromatography/mass spectrometry of the LiAlD4 depolymerization products. ω-Hydroxy acids were shown to be the major class of the aliphatic components of both the hypodermal (35%) and endodermal (28%) polymeric materials with the dominant chain length being C24 in the former and C16 in the latter. Nitrobenzene oxidation of the roots generated p-hydroxybenzaldehyde and vanillin with much less syringaldehyde. Electron microscopic examination of the hypodermal and endodermal cell walls from roots of corn plants grown in a Mg2+ -deficient (0.03 millimolar) nutrient solution showed that these walls were more heavily suberized than the analogous walls of roots from plants grown in normal (2 millimolar) Mg2+ levels. Analysis of the LiAlD4 depolymerization products of the suberin polymers from these roots showed that the roots grown in low Mg2+ had 3.5 times as much aliphatic suberin monomers on a weight basis as the roots from plants grown in nutrient with normal Mg2+ levels. Roots from plants grown in Mg2+ -deficient nutrient solution released 3.8 times the amount of aromatic aldehydes upon nitrobenzene oxidation as that released from normal roots. As the degree of Mg2+ deficiency of the nutrient solution was increased, there was an increase in the aliphatic and aromatic components characteristic of suberin. Thus, both ultrastructural and chemical evidence strongly suggested that Mg2+ deficiency resulted in increased suberization of the cell walls of both hypodermis and endodermis of Zea mays roots. The roots from Mg2+ -deficient plants also had a higher amount of peroxidase activity when compared to control roots. Images Fig. 1-3 PMID:16663407

  8. Long anterior mandibular tooth roots in Neanderthals are not the result of their large jaws.

    Le Cabec, Adeline; Kupczik, Kornelius; Gunz, Philipp; Braga, José; Hublin, Jean-Jacques


    Tooth root length has been shown to taxonomically distinguish Neanderthals from modern humans. However, this may result from differences in jaw size between both taxa, although most previous studies have revealed a very low or non-existent correlation between tooth size and jaw size in recent modern humans. We therefore investigated, within a broader taxonomical frame, to what extent measurements on the anterior tooth roots and the symphyseal region covary. Our samples comprise permanent mandibular incisors and canines from Mauer, Neanderthals, and extant and fossil modern humans sensu lato. Using micro-computed tomography, we took linear and cross-sectional surface area measurements of the roots and the symphyseal region and calculated the root volume. We also measured 3D landmarks to quantify the overall size of the mandible using centroid size. Furthermore, we analyzed the relationship between root size and symphyseal shape, based on Procrustes shape variables of semi-landmarks along the symphyseal outline. Our results show that Neanderthals have significantly larger anterior tooth roots than recent modern humans in terms of root length, mid-sagittal surface area and volume, even after correction for mandibular size. In contrast, symphyseal height and width do not differ significantly between both taxa, whereas, without scaling, the mid-sagittal symphyseal surface area and the centroid size of the mandible do differ. Importantly, no significant correlation was found between any of the root and symphyseal measurements after correction for overall mandibular size. The shape analyses revealed that Neanderthals have a vertical symphyseal profile with an evenly-thick symphysis, whereas recent modern humans display an unevenly-thick symphysis, comprising a pronounced incurvatio mandibularis and a bony chin. These results suggest a negative evolutionary allometry for the recent modern human anterior root size. Therefore, root length and other root dimensions can be

  9. Current trends in the diagnosis and treatment of tuboovarian abscess

    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 polymicrobial with a preponderance of anaerobic organisms. An initial conservative antimicrobial approach to the management of the unruptured tuboovarian abscess is appropriate if the antimicrobial agents used can penetrate abscesses, remain active within the abscess environment, and are active against the major pathogens in tuboovarian abscess, including the resistant gram-negative anaerobes such as Bacteroides fragilis and Bacteroides bivius. However, if the patient does not begin to show a response within a reasonable amount of time, about 48 to 72 hours, surgical intervention should be undertaken. Suspicion of rupture should remain an indication for immediate operation. Once operation is undertaken, a conservative approach with unilateral adnexectomy for one-side tuboovarian abscess is appropriate if future fertility or hormone production is desired.

  10. Anorectal abscess during pregnancy.

    Koyama, Shinsuke; Hirota, Masaki; Kobayashi, Masaki; Tanaka, Yusuke; Kubota, Satoshi; Nakamura, Ryo; Isobe, Masanori; Shiki, Yasuhiko


    Anorectal symptoms and complaints caused by hemorrhoids or anal fissures are common during pregnancy. It is known that one-third of pregnant women complain of anal pain in the third trimester. Anal pain may be caused by a wide spectrum of conditions, but if it begins gradually and becomes excruciating within a few days it may indicate anorectal abscess. We experienced a case of anorectal abscess during pregnancy which was diagnosed by magnetic resonance imaging and treated by incision and seton drainage at 36 weeks of gestation, followed by a normal spontaneous delivery at 38 weeks of gestation. To our knowledge, this is the first case report of anorectal abscess during pregnancy in the English-language published work. The clinical course of our case and clinical considerations of anorectal abscesses are discussed.

  11. Severe root resorption resulting from orthodontic treatment: Prevalence and risk factors

    Caroline Pelagio Raick Maués


    Full Text Available OBJECTIVE: To assess the prevalence of severe external root resorption and its potential risk factors resulting from orthodontic treatment. METHODS: A randomly selected sample was used. It comprised conventional periapical radiographs taken in the same radiology center for maxillary and mandibular incisors before and after active orthodontic treatment of 129 patients, males and females, treated by means of the Standard Edgewise technique. Two examiners measured and defined root resorption according to the index proposed by Levander et al. The degree of external apical root resorption was registered defining resorption in four degrees of severity. To assess intra and inter-rater reproducibility, kappa coefficient was used. Chi-square test was used to assess the relationship between the amount of root resorption and patient's sex, dental arch (maxillary or mandibular, treatment with or without extractions, treatment duration, root apex stage (open or closed, root shape, as well as overjet and overbite at treatment onset. RESULTS: Maxillary central incisors had the highest percentage of severe root resorption, followed by maxillary lateral incisors and mandibular lateral incisors. Out of 959 teeth, 28 (2.9% presented severe root resorption. The following risk factors were observed: anterior maxillary teeth, overjet greater than or equal to 5 mm at treatment onset, treatment with extractions, prolonged therapy, and degree of apex formation at treatment onset. CONCLUSION: This study showed that care must be taken in orthodontic treatment involving extractions, great retraction of maxillary incisors, prolonged therapy, and/or completely formed apex at orthodontic treatment onset.

  13. Central corneal abscess.

    van Bijsterveld, O P


    Central corneal abscess developed in the experimental animal after inoculation of biologically active staphylococcal strains in a paracentral epithelial lesion of the cornea. These abscesses did not ulcerate, developed only with high inocula, occurred more frequently in immunized rabbits. A serpiginous type of ulceration did not develop at the site of the initial epithelial lesion nor at any other place in the cornea. Histologically, the lesions consisted of densely packed polymorphonuclear leukocytes between the corneal lamellae.

  14. [Acute periproctal abscesses].

    Slauf, P; Antoš, F; Marx, J


    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.

    Full Text Available Objective: Psoas abscess (PA is a rare infection disease, which is difficult to diagnose. In the present study, we aimed to evaluate etiological factors and treatment results of patients with PA. Methods: Files of 20 patients who were diagnosed as PA between December 2006 and January 2013, were retrospectively analyzed. Patient’s whose data were entirely reached and diagnosed by Ultrasonography and/or Computed Tomography as an exact PA were included to the study. Results: The mean age of the 20 patients was 48.8 (range 17-82 year, and 6 of them were female and remaining were male. Psoas abscess were on the right side in 12 patients (60%, on the left side in seven patients (35%, and bilateral in one (5%. According to data records four patients had Diabetes Mellitus (20%, two had Hypertension (10%, one had cerebrovascular disease (5%, one had tuberculosis (5%, one had hyperthyroidism (5%, one had mental retardation (5%, and one had paraplegia (5%. Six case (30% were diagnosed as a primary psoas abscess (pPA, sPA and remaining (n=14, %70 were diagnosed as secondary. Percutaneous drainage was performed to 13 patients (65% and exploration was performed to three patients (15% as a treatment modality. Remaining four patients (20% were followed by medical treatment. Conclusion: Psoas abscess is rare and have variable and non-specific clinical characteristic, which may lead to difficulty in diagnosis. In developed and developing countries, it has been reported that the most common causes of sPA are Pott's disease, and Crohn's disease, also it should be taken into account that open surgery and urinary tract stone disease can receive a significant portion of the etiological factors.

    N Suneetha


    Full Text Available Background: Knowledge of the culture and sensitivity pattern is necessary, for the institution of appropriate empirical antibiotic therapy in orbital abscess. Objective: The objective of this study is to describe culture and sensitivity patterns of specimens from the orbit and surrounding structures. Materials and Methods: Retrospectively the medical records of 56 cases of orbital abscess were reviewed. Results: Cultures were positive in 38/56 (68.8% orbital specimens and the organisms included Staphylococcus aureus 18, Streptococci 7, Pseudomonas aeruginosa 3, 2 each of Enterobactersp, Escherichia coli, Proteus mirabilis, Acinetobacter sp. and 1 each of Actinomyces israelii, Diptheroids, Coagulase negative Staphylococcus, Citrobacter freundii, Methicillin-resistant S. aureus and Enterococcus faecalis. Four had polymicrobial infection. Culture of purulent nasal discharge, swabs taken from foci of infection on the face, and blood cultures were done in 26/56, and positive cultures were obtained in 16/26 (61.5% specimens. In 12 patients, there was a concurrence in the organism cultured from the orbit and from cultures from other sites. Gram-negative organisms were associated with increased ocular morbidity. Conclusion: Gram-positive cocci, especially S. aureus are the most common organisms isolated from orbital abscesses. Infections by Gram-negative organisms were associated with more complications. Empirical intravenous antibiotic therapy should have a broad spectrum of activity effective against a wide range of Staphylococcal organisms and Gram-negative bacilli.

    V R Borade


    Full Text Available Objectives: Objectives of this study were to review our experience in on otogenic brain abscess and its management by transmastoid drainage and compare the results. Materials and Methods: All patients with brain abscess secondary to CSOM presenting to our department from January 1997 to December 2010 were included in this study. All patients subjected to clinical, neurological, opthalmological examination and CT scan was done as an imaging modality. All patients managed by radical mastoidectomy or modified radical mastoidectomy and transmastoid drainage of brain abscess as neurosurgical facility not available. Results: Seventy-two patients in whom brain abscess secondary to chronic suppurative otitis media was diagnosed and has been treated since 1997 are presented. 85% of patients were below 20 years of age. More than 50% patients presented with more than one complication of chronic suppurative otitis media. 85% of patients were having extensive cholesteatoma and 15% patients were having extensive granulations in middle ear and mastoid air cells. 83% patients were having cerebellar abscess while 17% patients were having temporal lobe abscess. 80% of the pus culture was sterile while in 20% patients various microorganisms such as Proteus spp., Escherichia coli, Pseudomonas aeruginosa, Staphylococcus spp., and Streptococcus spp were cultured. Overall mortality in this series was 4.4%. Conclusion: In diagnosis of otogenic brain abscess CT scan with constrast is of immense help. Transmastoid drainage of brain abscess is a safe and effective method that can be performed by otologists in cases of otogenic brain abscess.

  19. Treatment of bacterial brain abscess by repeated aspiration. Follow up by serial computed tomography

    Yamamoto, Masaaki; Fukushima, Takeo; Hirakawa, Katsuyuki; Kimura, Hideo; Tomonaga, Masamichi [Fukuoka Univ. (Japan). School of Medicine


    Bacterial brain abscess often requires repeated aspiration before the abscess finally resolves. However, there are no guidelines for treatment by aspiration; for example, when should the abscess be tapped again, or when can an abscess be treated by antibiotics alone without further aspiration. Eleven patients with bacterial brain abscess treated by aspiration were evaluated to establish treatment guidelines for brain abscess, in particular the abscess size on serial computed tomography (CT) after aspiration. CT was performed about 24 hours after aspiration to evaluate the size of the abscess, and almost weekly during follow up. The diameter of the brain abscess before and after the initial and last aspirations were reviewed. In eight of the 11 patients, abscesses were aspirated repeatedly: two to three times in most patients. The diameter of the abscesses was 2.5-4.5 cm (mean 3.5 cm) before the last aspiration, and 1.4-3.4 cm (mean 2.3 cm) after the last aspiration, or when continuous drainage was discontinued. Perifocal edema was moderately decreased within 3 weeks after the last aspiration by medical treatment alone, with a concomitant decrease in the volume of the abscess. There were no deaths, and most patients had a favorable outcome. These results suggest that after the diameter of the abscess becomes less than 2 to 3 cm and does not increase anymore on serial CT, medical treatment alone can be anticipated to give satisfactory results without further aspiration.

  1. Radiological diagnosis of Brodie's abscess.

    Kowalewski, Michał; Swiatkowski, Jan; Michałowska, Ilona; Swiecicka, Dorota


    Background. Brodie's abscess is a kind of rare subacute or chronic osteitis. It is probably caused by mistreated or non-treated osteitis, or by bacteria of low virulence. Material and methods. In the Orthopedic and Traumatology Clinic of our medical school 5 patients were diagnosed with Brodie's obsecess between 1999 and 2002. all the patients had conventional x-rays, while one also had CT and MRI. Results and conclusions. The typical x-ray image shows an osteolytic lesion with sclerotic margin in the diametophysis. Each of the 5 patients had surgery. In 4 cases the histopatological results confirmed the radiological diagnosis. In one case fibrous dysplasia was found.

  3. A case of odontogenic brain abscess arising from covert dental sepsis

    Clifton, TC; Kalamchi, S


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

  4. Iliacus abscess with radiculopathy mimicking herniated nucleus pulposus: Additional diagnostic value of magnetic resonance imaging.

    Kim, D H; Woo, S H; Lee, W J


    An iliacus abscess is an extremely rare cause of low back pain. With an iliacus abscess, the classical signs seen with a psoas abscess are frequently absent. Therefore, a timely diagnosis at the initial visit is difficult and inadequate treatment usually results in high mortality. Here, we report the case of 19-year-old man who presented with acute low back pain with radiculopathy and was ultimately diagnosed with an iliacus muscle abscess.

  5. [The role of echography in osteolytic tubercular abscesses].

    Gandolfo, N; Serrato, O; Sandrone, C; Serafini, G


    Tubercular abscesses are relatively common complications of tubercular spondylodiscitis. Fifty-one patients with suspected abscesses were selected from a group of 97 patients with tubercular spondylodiscitis and submitted to US. In 10 cases CT was performed before US and detected 7 abscesses, all of them confirmed by US. In the extant 41 cases, CT followed US; in 13 cases only US poorly visualized ilio-psoas muscles. As for the group of 23 patients who underwent both CT and US, if the former method is assumed as the reference gold standard, overall US sensitivity is 97% (1 false negative) and its specificity is 100%. In all cases where US findings were accurate and specific enough, CT was not performed; the patients were followed every seventh month and no abscesses found. US showed abscesses in the iliac fossa in 20 cases, along the psoas fascia in 6 and in the thighs in 3 cases. Two cases of gluteal localization were observed, together with 1 Grynfelt's triangle abscess, 1 Petit's triangle and 1 Scarpa's triangle abscesses; finally, 1 abscess was found in the knee. The most common appearance of tubercular abscesses is a hypoechoic and inhomogeneous pattern; sometimes caseum makes the abscess solid and hyperechoic. Calcifications were unusual in our series. All patients were submitted to percutaneous drainage under US guidance. The results proved US to allow the early and unquestionable diagnosis of tubercular abscesses and to confirm clinical suspicion. Moreover, US is also useful to guide percutaneous drainage and to follow the patients after drainage. As for CT, it remains the method of choice to depict vertebral involvement, but, in our series, it exhibited no significant advantages over US in the study of abscessual lumbar collections.

    Rustam Khan; Saeed Hamid; Shahab Abid; Wasim Jafri; Zaigham Abbas; Mohammed Islam; Hasnain Shah; Shaalan Beg


    AIM: To determine the predictive factors for early aspiration in liver abscess.METHODS: A retrospective analysis of all patients with liver abscess from 1995 to 2004 was performed. Abscess was diagnosed as amebic in 661 (68%) patients, pyogenic in 200 (21%), indeterminate in 73 (8%) and mixed in 32 (3%). Multiple logistic regression analysis was performed to determine predictive factors for aspiration of liver abscess.RESULTS: A total of 966 patients, 738 (76%) male, mean age 43 ± 17 years, were evaluated: 540 patients responded to medical therapy while adjunctive percutaneous aspiration was performed in 426 patients. Predictive factors for aspiration of liver abscess were: age ≥ 55 years, size of abscess ≥ 5 cm, involvement of both lobes of the liver and duration of symptoms ≥ 7 d. Hospital stay in the aspiration group was relatively longer than in the non aspiration group. Twelve patients died in the aspiration group and this mortality was not statistically significant when compared to the non aspiration group.CONCLUSION: Patients with advanced age, abscess size > 5 cm, both lobes of the liver involvement and duration of symptoms > 7 d were likely to undergo aspiration of the liver abscess, regardless of etiology.

  7. A Rare Case of Fusobacterium Necrophorum Liver Abscesses

    Hannoodi, Faris; Sabbagh, Hussam; Kulairi, Zain; Kumar, Sarwan


    Liver abscesses are an uncommon disease that can present with vague symptoms. Fusobacterium necrophorum causing liver abscesses is a rare condition and only a few cases have been reported. An 88-year-old female presented to her primary care physician with one week of fevers, night sweats, chills, fatigue and vague right upper quadrant abdominal pain. She denied nausea, vomiting, constipation, diarrhea and unintentional weight loss. A computed tomography scan of the abdomen showed two liver abscesses in the right lobe as well as extensive diverticulosis. Percutaneous drainage was performed and draining catheters were placed in the abscesses. Culture of the abscess fluid grew Fusobacterium necrophorum. She was treated with ceftriaxone and metronidazole as per sensitivities. Rare cases of F. necrophorum hepatic abscesses have been published. The source of infection described in reported cases included hematogenous spread from dental caries/peritonsillar abscess and those involving the gastrointestinal tract resulting from inflammation of the bowel wall or from inflamed diverticuli via the portal circulation. In one study, thirteen cases of liver abscess due to F. necrophorum were studied, and two of these cases had diverticular disease without inflammation.

    Cheng-Lin Wang; Xue-Jun Guo; Shui-Bo Qiu; Yi Lei; Zhi-Dong Yuan; Han-Bin Dong; Hui-An Liu


    BACKGROUND: Bacterial hepatic abscess usually is acute and progressive, often resulting in sepsis, impairment of liver function and disseminated intravascular coagulation. The mortality rate was as high as 80%in the past. For the purpose of early diagnosis and differential diagnosis of this disease, we probed the imaging manifestations and their characteristics in bacterial hepatic abscesses by CT scan. METHODS:Twenty-four lesions from 21 patients with bacterial hepatic abscesses that were conifrmed by clinical features, puncture and culture were reviewed for CT manifestations. Fourteen patients were male and 7 were female, with an average age of 56.2 years. All lesions underwent CT plain scan and three-phase enhanced scan and 15 patients underwent delayed-phase imaging. Three senior radiologists read the iflms in accordance with a standard. RESULTS: Among 24 lesions, 18 (75%) were situated in the right liver with diameters of 1.4-9.3 cm (average 4.5 cm). Nineteen (79.2%) lesions were round or sub-round in shape, and 22 (91.7%) had smooth, uninterrupted and sharp edges. All lesions showed low attenuation of less than 20 Hu. Twenty-two enhanced lesions (91.7%) had rim-shaped enhancement in the abscess wall, and 13 (54.2%) showed single or double-ring signs. Eighteen (75%) displayed honeycomb-like, grid-like or strip-like enhancement. Eighteen (75%) were regionally enhanced in the surroundings or upper or lower layers. Only 2 (8.3%) displayed a gas-liquid surface sign. CONCLUSIONS:  The CT ifndings of bacterial hepatic abscess are usually typical, and the diagnosis of the abscess is not dififcult. To precisely diagnose atypical cases, it is necessary to combine CT with clinical observations and follow-up.

  9. Rectus sheath abscess after laparoscopic appendicectomy

    Golash Vishwanath


    Full Text Available Port site wound infection, abdominal wall hematoma and intraabdominal abscess formation has been reported after laparoscopic appendicectomy. We describe here a rectus sheath abscess which occurred three weeks after the laparoscopic appendicectomy. It was most likely the result of secondary infection of the rectus sheath hematoma due to bleeding into the rectus sheath from damage to the inferior epigastric arteries or a direct tear of the rectus muscle. As far as we are aware this complication has not been reported after laparoscopic appendicectomy.

  10. Mycobacterium fortuitum abdominal wall abscesses following liposuction

    Al Soub Hussam


    Full Text Available We describe here a case of abdominal abscesses due to Mycobacterium fortuitum following liposuction. The abscesses developed three months after the procedure and diagnosis was delayed for five months. The clues for diagnosis were persistent pus discharge in spite of broad spectrum antibiotics and failure to grow any organisms on routine culture. This condition has been rarely reported; however, the increasing number of liposuction procedures done and awareness among physicians will probably result in the identification of more cases. Combination antibiotic therapy with surgical drainage in more extensive diseases is essential for cure.

  11. Orthodontic Elastic Separator-Induced Periodontal Abscess: A Case Report

    Talia Becker


    Full Text Available 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.

  12. Empirical antimicrobial therapy of acute dentoalveolar abscess

    Matijević Stevo


    Full Text Available Background/Aim. The most common cause of acute dental infections are oral streptococci and anaerobe bacteria. Acute dentoalveolar infections are usually treated surgically in combination with antibiotics. Empirical therapy in such infections usually requires the use of penicillin-based antibiotics. The aim of this study was to investigate the clinical efficiency of amoxicillin and cefalexin in the empirical treatment of acute odontogenic abscess and to assess the antimicrobial susceptibility of the isolated bacteria in early phases of its development. Methods. This study included 90 patients with acute odontogenic abscess who received surgical treatment (extraction of a teeth and/or abscess incision and were divided into three groups: two surgicalantibiotic groups (amoxicillin, cefalexin and the surgical group. In order to evaluate the effects of the applied therapy following clinical symptoms were monitored: inflammatory swelling, trismus, regional lymphadentytis and febrility. In all the patients before the beginning of antibiotic treatment suppuration was suched out of the abscess and antibiotic susceptibility of isolated bacteria was tested by using the disk diffusion method. Results. The infection signs and symptoms lasted on the average 4.47 days, 4.67 days, and 6.17 days in the amoxicillin, cefalexin, and surgically only treated group, respectively. A total of 111 bacterial strains were isolated from 90 patients. Mostly, the bacteria were Gram-positive facultative anaerobs (81.1%. The most common bacteria isolated were Viridans streptococci (68/111. Antibiotic susceptibility of isolated bacteria to amoxicillin was 76.6% and cefalexin 89.2%. Conclusion. Empirical, peroral use of amoxicillin or cefalexin after surgical treatment in early phase of development of dentoalveolar abscess significantly reduced the time of clinical symptoms duration in the acute odontogenic infections in comparison to surgical treatment only. Bacterial strains

  13. The infected heart: ventriculoseptal abscess and intracardiac fistulization.

    Habeeb, Keith; Stankewicz, Holly; Axelband, Jennifer; Melanson, Scott


    Infective endocarditis is a rare but potentially deadly infection of the endocardial layer, which can involve the valves of the heart among other structures. The extraordinarily rare complication seen in this case involves extensive damage manifesting in an aortic root abscess resulting in an abnormal communication between the aorta and the atrium known as an aortocavitary fistula (Eur Heart J 2005;26:288-297; Pediatr Cardiol 2011;32:1057-1059; J Am Coll Cardiol 1991;18:663-667). As the disease progresses, wading through the complex symptoms, which may seem unrelated, represents a key challenge in diagnosis. This case describes both early and late findings of endocarditis and highlights a rare complication in which rapid diagnosis and early surgical intervention before the development of hemodynamic sequelae are paramount. In this case, infective endocarditis, a great masquerader in this case, provided a challenging diagnostic situation, a very rare complication, and commonalities of disease characteristics that health care provider should appreciate.

  14. Brain abscess: Current management

    Alvis Miranda, Hernando; Castellar-Leones, Sandra Milena; Elzain, Mohammed Awad; Moscote-Salazar, Luis Rafael


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

  16. Pyogenic Liver Abscess Caused by Burkhoderia pseudomallei in Taiwan

    Yu-Lin Lee


    Full Text Available Pyogenic liver abscess in Taiwan is a well-known disease entity, commonly associated with a single pathogen, Klebsiella pneumoniae. Melioidosis is an endemic disease in Taiwan that can manifest as multiple abscesses in sites including the liver. We report three cases of liver abscesses caused by Burkholderia pseudomallei. The first patient was a 54-year-old diabetic woman, who presented with liver abscess and a left subphrenic abscess resulting from a ruptured splenic abscess, co-infected with K. pneumoniae and B. pseudomallei. The second patient, a 58-year-old diabetic man, developed bacteremic pneumonia over the left lower lung due to B. pseudomallei with acute respiratory distress syndrome, and relapsed 5 months later with bacteremic abscesses of the liver, spleen, prostate and osteomyelitis, due to lack of compliance with prescribed antibiotic therapy. The third patient was a 61-year-old diabetic man with a history of travel to Thailand, who presented with jaundice and fever of unknown origin. Liver and splenic abscesses due to B. pseudomallei were diagnosed. A high clinical alertness to patients' travel history, underlying diseases, and the presence of concomitant splenic abscess is essential to early detection of the great mimicker, melioidosis. The treatment of choice is intravenous ceftazidime for at least 14 days or more. An adequate duration of maintenance oral therapy, with amoxicillin-clavulanate or trimethoprim-sulfamethoxazole for 12-20 weeks, is necessary to prevent relapse. Liver abscess in Taiwan is most commonly due to K. pneumoniae, but clinicians should keep in mind that this may be a presenting feature of melioidosis.



    Full Text Available ABSTRACT Objective: To determine the efficacy of anesthetic transforaminal nerve root block in patients with sciatica secondary to lumbar disc herniation through a prospective observational study. Methods: The study included 176 patients from a private clinic undergoing transforaminal injection performed by a single spinal surgeon. The patients were assessed after two weeks, three months and six months regarding to the improvement of the pain radiating to the lower limbs. In case of persistent symptoms, patients could choose to perform a new nerve root block and maintenance of physical therapy or be submitted to conventional microdiscectomy. Results: By the end of six-month follow-up of the 176 patients, 116 had a favorable outcome (95 after one block and 21 after two blocks, and only 43 required surgery. Conclusion: The results of our study suggest a positive effect of transforaminal block for the treatment of sciatica in patients with lumbar disc herniation.

  18. [Endosonography control of percutaneous paracoccygeal drainage of deep pelvic abscesses after rectum resection].

    Truong, S; Willis, S; Jansen, M; Neuerburg, J; Schumpelick, V


    Pelvic abscesses are severe complications after rectal surgery. In recent years, surgical drainage has been edged out by percutaneous drainage techniques. We report our experience with the drainage of postoperative pelvic abscesses via the paracoccygeal route controlled by endosonography. In eight patients the diagnosis of a retrorectal pelvic abscess was established by endosonography and confirmed by endosonographically controlled exploratory puncture. Drainage of the abscesses was performed via the paracoccygeal access route by trocar or Seldinger technique under permanent visual control by endoluminal sonography. Irrigation of the abscess cavity was than performed daily. In all cases drainage was successful without complications. Duration of drainage was 9-14 days with a mean of 10.8 days. In one patient there was a recurrence of the abscess because of early removal of the drainage catheter. Because of its overall availability and its good results, paracoccygeal percutaneous endosonographically controlled drainage seems to be a suitable uncomplicated method for drainage of postoperative pelvic abscesses.

  19. Amebic liver abscess in Iranian children

    Khotaii Gh


    Full Text Available Although amebic liver abscess can be a cause of significant morbidity and mortality in all ages, there are few reports dealing with this entity in children. Twenty-four children with amebic liver abscess. Ages ranging between 8 weeks and 14.5 years were managed at the Tehran university hospital of children, Iran, between November 1987, and October 2001. The most frequency presentation was high-grade fever and right upper quadrant pain, associated with tender hepatomegaly, leukocytosis and an elevated erythrocyte sedimentation rate. The diagnosis was confirmed by elevated indirect hemagglutination titers and ultrasonograpy of the liver. Unlike the experience in adult patients, none of the patients had concomitant jaundice and significant derangement of liver enzymes. The abscesses were likely to be solitary (22 of 24 patients. There were 17 males and 7 females. Most patients (80% were between 8 weeks to 14.5 years of age. In five patients possible predisposing factors were tuberculosis, chickenpox, tetralogy of fallot and thalassemia major. All patients received metronidazole (50 mg/kg/day, followed by a therapeutic course of a luminal amebicide. There was no death despite a mean delay of 15 days before presentation to our hospital. In conclusion a high index of suspicion, early institution of metronidazole therapy and aspiration of abscesses with potential to rupture are believed to have contributed to the better outcome in these children when compared with results in previous reports.

  20. Diagnosis and treatment of prostatic abscess

    Paulo Oliveira


    Full Text Available OBJECTIVES: Present and discuss the pathogenesis, diagnostic methods and treatment of the prostatic abscess. MATERIALS AND METHODS: We have retrospectively studied the medical records of 9 patients diagnosed and treated for prostatic abscess, between March 1998 and December 2000, assessing age, context, associated diseases, and diagnostic and therapeutic methods. We have compared the data found with those described in literature, based on Medline data. RESULTS: Mean age was 52.6 years. Three patients had previous diabetes mellitus diagnosis, and one was infected by HIV virus. Transrectal ultrasound of the prostate confirmed the diagnosis of prostatic abscess in all 7 cases in which it was performed. All cases received antibiotic treatment, and 77.8% needed concomitant surgical treatment. Two cases of microabscess were treated only with antibiotics. Four patients were submitted to perineal catheter drainage, 2 were submitted to transurethral resection of the prostate (TURP, and one patient required both procedures. Mean hospitalization time was 11.2 days, and most frequent bacterial agent was S. aureus. All patients were discharged from the hospital, and there was no death in this series. CONCLUSIONS: Prostatic abscess should be treated with broad-spectrum antibiotics and surgical drainage (perineal puncture or TURP. Microabscess may heal without surgery.

  6. [Giant liver abscess due to nearly asymptomatic choledocholithiasis].

    Colović, Radoje; Grubor, Nikica; Colović, Natasa


    Solitary pyogenic liver abscess is usually caused by a metastatic infection through the portal blood flow or through the hepatic arterial blood flow from extra-abdominal pyogenic foci. Besides, it may be the result of local inflammatory diseases, such as cholecystitis, hydatid cyst, haematomas particularly with retained foreign bodies, etc. Suppurative cholangitis usually causes multiple pyogenic liver abscesses. Solitary pyogenic abscess is rarely caused by cholangitis, but practically always by suppurative cholangitis. Giant pyogenic liver abscess due to asymptomatic or mild cholangitis is a rarity. We present on a 63 year old man who developed a giant solitary pyogenic liver abscess in whom no other possible cause could be found or anticipated except practically almost asymptomatic choledocholithiasis accompanied with mild elevation of bilirubin content, alkaline phosphatase and gamma-GT. The patient was successfully treated operatively. Over 1800 ml. of pus was aspirated from the abscess cavity. Operative cholangiography performed in spite of the absence of gall bladder stones undilated and noninflamed common bile duct stone showed a small nonobstructing distal common bile duct stone. The duct was not dilated, the bile was clear and there were no signs of cholangitis in the inside of the common bile duct. Cholecystectomy and abscess cavity drainage led to uneventful recovery. The patient has been symptom-free for more than 3.5 years.

    Full Text Available Objective. To evaluate the association between abscess size and duration of hospitalization and need for surgical intervention. Methods. We collected data from patients admitted with ICD-9 codes 614.9 (PID and 614.2 (TOA from January 1, 1999—December 31, 2005. We abstracted data regarding demographics, diagnostic testing/laboratory testing, imaging, treatment, and clinical course. Two abscess groups were created: ≤8 cm or >8 cm. Descriptive statistics were calculated, and duration of hospitalization and surgical intervention for women with large abscesses were compared to women with smaller collections. Results. Of the 373 charts reviewed, 135 had a TOA and 31% required management with drainage and/or surgery. The average abscess size for those treated successfully with conservative management was 6.3 cm versus those requiring drainage and/or surgery (7.7 cm, P=.02. Every 1 cm increase in abscess size as associated with an increase in hospitalization by 0.4 days (P=.001. Abscesses greater than 8 cm were associated with an increased risk of complications (P<.01. Conclusions. Larger tubo-ovarian abscesses are associated with an increased duration of hospitalization and more complications including an increased need for drainage or surgery. Additional research to determine the most efficacious antibiotic regimen management strategy is needed.

  8. Oral microbiota species in acute apical endodontic abscesses

    Noelle George


    Full Text Available 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

  9. Dental abscess: A microbiological review



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

    Khan A Nazir


    Full Text Available Background: To describe our experience of paediatric patients with acute retropharyngeal abscess in terms of clinical presentation, diagnosis, management and complications. Materials and Methods: A prospective study was done for a period of 4 years (Jan 2009 to Jan 2013 on paediatric patients (< 15 years with acute retropharyngeal abscess at two tertiary hospitals in Srinagar. Diagnosis was made on the basis of X-ray, CECT scan findings and confirmed on incision and drainage. Pus was aspirated from all patients and sent for culture and sensitivity. Data for clinical presentation, X-ray, CECT scan findings, causes, complications, bacteriology and management were collected. Thirty-five abscesses were drained while 5 with small abscesses on CECT were managed conservatively. Results: A total of 40 patients were diagnosed as acute retropharyngeal abscesses. Males were commonly affected, and most of the patients were less than 6 years of age. Most common symptom at presentation was fever (35 followed by neck pain (30 Dysphagia/odynophagia (22, swelling in neck (19. Most common clinical sign observed was oropharyngeal swelling and limitation of neck movements (30, cervical swelling/lymphadenopathy in 22 patients. Torticollosis and drooling were seen in 15 patients. Complications were seen in 8 patients. Most common X-ray finding was pre-vertebral thickening. Success rate with primary surgical drainage was 95% while 3 patients in conservative group failed. Conclusion: Children with RPA most commonly present with restricted neck movements, fever and cervical lymphadenopathy, and rarely with respiratory distress or stridor. Surgical intervention is necessary for most of these patients.

    The principle of operation and main parameters of the recently created scanning differential reverse microcalorimeter of the new generation are presented. The microcalorimeter is destined for studying water crystallization and ice melting processes in heterogeneous systems, including plant and animal cells and tissues in the temperature range of 20 to -55 degrees C. In order to obtain maximum information from the experimental results respective algorithms and applied software package were developed. The results of studies of water crystallization and ice melting processes in different parts of common plantain (Plantago major L.) root, as a certain model system, can give us information on the peculiarities of the studied processes in complex, heterogeneous systems.

  12. [Intracranial epidural abscess in a newborn secondary to skin catheter].

    Fernández, L M; Domínguez, J; Callejón, A; López, S; Pérez-Avila, A; Martín, V


    Intracranial epidural abscesses are uncommon lesions, being more frequents in older children and adults. They commonly arise as a result of direct extension of a preexisting infection and rarely present with focal deficit. We present a case of a 11-days old preterm infant who developed an intracranial epidural abscess as a result of an infected scalp vein catheter. The diagnosis was made on the basis of the cranial ultrasound and CT scan images. An identified strain of Enterococcus faecium was cultured from all the samples. The patient underwent a right frontal craniotomy with drainage of the abscess and a 2-week total course of intravenous antibiotics was administrated. CT scan imaging 3 week after the procedure demonstrated no evidence of residual lesion. When present, a scalp vein catheter, in absence of others predisponing factors, must be considered as an etiologic agent for an intracranial epidural abscess in this age-group.

    Full Text Available The genotoxicity of the pesticide Folpan was evaluated in meristematic root cells of Tulipa gesneriana cv. ‘Leen van der Mark’. The statistical analyses of the results showed that the pesticide studied has a concentration-dependent toxicity and induces chromosomal aberrations. The lowest mitotic index (2,69% was related with the highest tested concentration of Folpan (900 ppm. Various types of chromosomal and mitotic abnormalities such as binucleated cells, laggards, and disturbed ana-telophase with multiple chromosomal bridges revealed the clastogenic potential of pesticide tested.

  14. Submasseteric abscess: A rare head and neck abscess

    Ashutosh Rai


    Full Text Available The objective of the article is to highlight and make people aware of a rare abscess which is often missed or misdiagnosed. As only a few cases have been reported, the authors feel that reporting such a case would help in proper management of the disease. We are presenting a 6.5-year-old male child with 3 weeks history of right facial swelling in the parotid region, with low-grade fever and trismus. Submasseteric abscess is a rare abscess which is often misdiagnosed as a parotid abscess or parotitis. Only a few cases have been reported. The cause is mostly dental in origin. Intravenous antibiotics often fail to alleviate the symptoms as this is a closed space and needs prompt drainage. Therefore, awareness of this complication of dental infections is vital for proper diagnosis and timely management.

  15. Liver abscesses with pyopericardium: Laparoscopic management in a preterm neonate

    Ravishankaran Praveen


    Full Text Available We report a 28-day-old neonate presenting with signs of fever, abdominal distension, and refusal to feed. The baby was diagnosed to have multiple liver abscesses which ruptured and a tract lead to the pericardium resulting in a pyo-pericardium. Laparoscopic drainage of the abscess cavities and the pyo-pericardium was performed. An extensive search of the literature revealed that this case is the youngest one to have undergone such simultaneous laparoscopic drainage.

  16. Subperiosteal abscess in a child. Trueta's osteomyelitis hypothesis undermined?

    Weenders, S G M; Janssen, N E; Landman, G W D; van den Berg, F P


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

    Polymerase chain reaction (PCR) has been applied in diagnosing amebic liver infection by detecting pathogenic Entamoeba histolytica DNA in liver aspirates. Oligonucleotide primers found to he specific for the gene encoding the 30 kDa molecule of this pathogenic ameba were used in the test. Liver aspirates obtained from 23 patients with amebic liver abscess substantiated by typical clinical rnanifastation or with very high titres of anti-E histtolytica antibodies by ELISA were found to he positive by PCR. Fourteen controlsamples (3 cases of bacterial liver abscess, I of liver cancer and 10 of other abscess) were all found to be negative to this reaction. The results suggested PCR to he a specific and sensitive tool for diagnosing amebic liver abscess infections.

  18. Ultrasound-guided drainage of deep pelvic abscesses

    Lorentzen, Torben; Nolsøe, Christian; Skjoldbye, Bjørn


    The aim of this study was to demonstrate and evaluate the ultrasound-guided drainage of deep pelvic abscesses in which transabdominal percutaneous access could not be performed because of overlying structures. A retrospective analysis of 32 consecutive patients with 33 deep pelvic abscesses...... (median diameter 7 cm), 19 were treated with catheter drainage and 18 of these cases resulted in favorable clinical outcomes. Of the smaller abscesses (median diameter 4 cm), 14 were treated with needle drainage. In two of these cases, follow-up US showed that a repeat puncture and drainage was necessary...... and the subsequent in-dwelling catheter period, there were no serious complications related to the drainage procedures. We conclude that ultrasound-guided transrectal, transvaginal, transperineal and transgluteal drainage of deep pelvic abscesses are safe and effective treatment approaches. Based on our findings...

  19. Brodie's abscess of the cuboid in a pediatric male.

    Agarwal, Sharat; Akhtar, Mohammad Nasim; Bareh, Jerryson


    Brodie's abscess of the tarsal cuboid is a rare presentation of a common disease. In the present report, we describe the case of Brodie's abscess of the tarsal cuboid after a thorn prick in the foot of a 10-year-old boy. The patient was asymptomatic in the acute phase of the injury, and on presentation, no evidence was found of an open cutaneous wound. The foot radiographs showed a cavitary osteolytic lesion in the cuboid bone. Magnetic resonance imaging revealed a classic penumbra sign and an abscess in the plantar intrinsic musculature. The patient was treated with curettage and debridement combined with broad-spectrum antibiotics, which resulted in complete resolution of the symptoms by 6 weeks postoperatively. Although microbiologic analysis of the surgical specimen failed to reveal a causative microorganism, histopathologic inspection showed chronic inflammation, consistent with Brodie's abscess.

  20. Novel Peritonsillar Abscess Task Simulator.

    Taylor, Steven R; Chang, C W David


    The management of peritonsillar abscesses is a skill developed early in residency training. Although drainage is not technically complicated, the procedure is intimidating to the neophyte. Task simulators have become increasingly common to provide training opportunities in a controlled environment. The authors designed a peritonsillar abscess simulator using a latex moulage of the oral cavity and other common materials. Twelve medical professionals of various levels of experience were instructed to expose, anesthetize, aspirate, and drain the simulated abscess. After completion, a questionnaire was completed by each volunteer. Initial impressions were positive that the model adequately replicated the tasks requisite for abscess drainage and was suitable as an instructional device. The initial construct cost was approximately 10 dollars, with disposables costing roughly 25 cents. Further research is under way to formally assess the simulator for face, content, and construct validity.

  1. Splenic abscess: a rare presentation

    Mohit Bhatia


    Full Text Available Splenic abscess is a rare clinical entity with an incidence of 0.2-0.7% in autopsy-based studies. When untreated, splenic abscess is associated with nearly 100% mortality; in treated patients, the mortality rate is 16.6% during the first 90 days. It mostly occurs in patients with neoplasia, immunodeficiency, trauma, diabetes or splenic infarct. The incidence of splenic abscess is thought to be growing because of the increase in the number of immunocompromised patients who are particularly at risk for this disease and also because of the widespread use of diagnostic modalities. However, the optimal treatment for this remains unclear. We present a case of a 42-year-old man diagnosed with multiloculated splenic abscess and was subjected to splenectomy.

  2. Lingual abscess: a case report

    Bekele K


    Full Text Available Kebebe Bekele,1 Desalegn Markos2 1Department of Surgery, School of Medicine, Madda Walabu University, Bale Goba, 2Department of Neonatology Nursing, St. Paul Hospital Millennium Medical College, Addis Ababa, Ethiopia Background: Lingual abscesses have become extremely rare since the discovery of antibiotics, despite the relatively frequent exposure of tongue to bite trauma during mastication and seizures. It is a potentially life-threatening clinical entity. Even though there were some case reports on tongue abscess from overseas, none of them were reported from Africa, particularly from Ethiopia.Case presentation: A 36-year-old male patient with severe, continuous pain and swelling of tongue for 6 weeks was presented to Goba Referral Hospital. The swelling was 2 cm by 1 cm, located on posterior central tongue, and frank pus oozed from the center of the swelling. He had associated dysphagia, odynophagia, and speech difficulty. He had no previous personal and family history of similar illness and tonsillitis. Gram staining revealed the presence of Gram-positive cocci in clusters. Pyogenic lingual abscess was the diagnosis. Treatment included incision and drainage with the administration of systemic antibiotics, which covered both aerobic and anaerobic organisms, and anti-pain drugs. The condition did not relapse in 6 months of follow-up. Conclusion: Lingual abscess should be considered in patients presenting with tongue swelling, dysphagia, odynophagia, and speech difficulty. Since lingual abscess that occurs on the posterior part of the tongue has diagnostic difficulty, professionals in rural setup where diagnostic resources (such as ultrasound and magnetic resonance imaging are scarce should be careful not to misdiagnose it. Incision and drainage with the administration of systemic antibiotics and anti-pain drugs is an effective treatment option for lingual abscess. Keywords: lingual abscesses, tongue abscess, swelling, incision, drainage, case

The author discusses the pathology of hematologic osteomyelitis and its role in the development of a subacute abscess. A review of the literature and a detailed description of the pathogenesis of Brodie's abscess is submitted as well.

  4. Surgical Excision of a Symptomatic Thoracic Nerve Root Perineural Cyst Resulting in Complete Resolution of Symptoms: A Case Report.

    Aljuboori, Zaid; Yaseen, Alae; Simpson, Jessica; Boakye, Maxwell


    Tarlov (perineural) cysts of the nerve root are common and usually incidental findings during magnetic resonance imaging (MRI) of the lumbosacral spine. There are a few case reports where symptomatic thoracic perineural cysts have been described in the literature. We report a case of a high thoracic nerve root perineural cyst that failed conservative therapy, requiring surgical intervention. Our patient presented with radicular symptoms involving the left hand. Imaging workup revealed a cystic lesion of the left T1 nerve root at the level of the foramen. Surgical resection resulted in significant improvement in patient symptoms, and pathology revealed a perineural cyst. We conclude that a thoracic perineural (Tarlov) cyst can be symptomatic by causing nerve root compression and can be mistaken as a nerve root sheath tumor on imaging. Surgical treatment can be curative.

  5. Pathogenesis of Staphylococcus aureus abscesses.

    Kobayashi, Scott D; Malachowa, Natalia; DeLeo, Frank R


    Staphylococcus aureus causes many types of human infections and syndromes-most notably skin and soft tissue infections. Abscesses are a frequent manifestation of S. aureus skin and soft tissue infections and are formed, in part, to contain the nidus of infection. Polymorphonuclear leukocytes (neutrophils) are the primary cellular host defense against S. aureus infections and a major component of S. aureus abscesses. These host cells contain and produce many antimicrobial agents that are effective at killing bacteria, but can also cause non-specific damage to host tissues and contribute to the formation of abscesses. By comparison, S. aureus produces several molecules that also contribute to the formation of abscesses. Such molecules include those that recruit neutrophils, cause host cell lysis, and are involved in the formation of the fibrin capsule surrounding the abscess. Herein, we review our current knowledge of the mechanisms and processes underlying the formation of S. aureus abscesses, including the involvement of polymorphonuclear leukocytes, and provide a brief overview of therapeutic approaches.

  6. Brucellar spondylodiscitis: comparison of patients with and without abscesses.

    Kaptan, Figen; Gulduren, Hakki Mustafa; Sarsilmaz, Aysegul; Sucu, Hasan Kamil; Ural, Serap; Vardar, Ilknur; Coskun, Nejat Ali


    Brucellosis is an important cause of spondylodiscitis in endemic areas. Brucellar spondylodiscitis is a serious complication because of its association with abscess formation. Prospective studies comparing patients with and without abscesses are lacking. The objective of this study was to determine the frequency and demographic, clinical, laboratory, and radiological features of brucellar spondylodiscitis and to compare patients with and without abscesses regarding treatment and outcome. Out of 135 consecutive patients with brucellosis, 31 patients with spondylodiscitis were recruited for the study. Patients were grouped according to magnetic resonance imaging findings. The frequency of spondylodiscitis was 23.0 %. Sites of involvement were lumbar (58.1 %), lumbosacral (22.6 %), cervical (9.7 %), thoracolumbar (6.5 %), and thoracic (3.2 %). Abscesses occurred in 19 (61.3 %) patients and were associated with low hemoglobin levels. Medical treatment included a combination of streptomycin (for the first 3 weeks), doxycycline, and rifampin. The total duration of treatment was 12-39 (mean 17.0 ± 8.5 SD) weeks. By 12 weeks of treatment, evidence of clinical improvement (67 vs. 28 %) and radiological regression (92 vs. 50 %) was significantly greater in patients without abscesses. The duration of treatment was longer if an abscess was present. Two female patients with abscesses required surgical intervention. Both patients presented with high fever, neurologic deficit, and high Brucella standard tube agglutination test titers. Each patient should be evaluated individually, based on clinical findings, laboratory data, and radiological results, when undergoing treatment for brucellar spondylodiscitis. If abscesses are found, a longer course of treatment and even surgical intervention may be needed.

  7. Analysis of the Bacterial Diversity in Liver Abscess: Differences Between Pyogenic and Amebic Abscesses.

    Reyna-Fabián, Miriam E; Zermeño, Valeria; Ximénez, Cecilia; Flores, Janin; Romero, Miguel F; Diaz, Daniel; Argueta, Jesús; Moran, Patricia; Valadez, Alicia; Cerritos, René


    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.

  8. 十二指肠溃疡导致巨大肠系膜脓肿1例%A case of duodenal ulcer resulting in huge mesenteric abscess

    孙运秀; 陈立波


    Although the perforation caused by ulcer on posterior wall of duodenal is common,the perforation which locates in mesentery and leads to mesenteric abscess is rare. The clinical manifestation is not typical in this case. So it is easy to make missed or incorrect diagnosis. With the report of this case,there will be important mirror meaning on the diagnosis and treatment of mesenteric abscess merger duodenal fistula.

  9. Conservative management of post-appendicectomy intra-abdominal abscesses

    Dhaou Mahdi


    Full Text Available Abstract Purpose 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. Methods Hospital records of children treated in our unit for intra-abdominal post appendectomy abscesses over a 6 years period were reviewed retrospectively. Results 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. Conclusion Compared to surgical drainage, antibiotic management of intra-abdominal abscesses was a no invasive treatment with shorter hospitalization.

  10. [Amoebic liver abscess: echographic aspects].

    Niang, H E; Ka, M M; Badiane, M; Ba, A; Konde, L; Lamouche, P


    Amoebic liver abscess is the most frequent location of the extra-intestine amibiasis with an epidemio-endemic repartition in our areas. We are reporting in this study the main echographic patterns that can be found. 117 documents were collected and studied between 1982 and 1988 in the main hospitals of Dakar (SENEGAL). Most of the patients were young, the range of age being between 25 and 55 years old and 83% of them, were male. The diagnosis of the amoebic liver abscess was evocated on the basis of the following clinical and biological symptoms: 54.38% of painful haetomegaly, 42.10% of pleuro-pulmonary and digestive signs, 3.50% of long lasting isolated fever, non specific biological sign of inflammation, 74.57% of positive hemaglutination test. An echographic test was performed before the anti-parasitic treatment with an echotomograph PHILIPS SDR 1500 in real time using a probe of 3 MHZ. The amoebic abscess of liver was detected by the echography in all cases. The unique abscess (83.10%) was the most frequent form. It was localized in the right liver (64%) and had an heterogeneous echostructure (55.70%). The hypo-echogeneous form (36.50%) was the earlier stage of the collecting abscess. The liquid form (07.80%) was observed in the latter stages of the disease. Some difficulties to determine the amoebic abscess may appear when primitive liver cancer or pyogensus abscess are present. In these cases it is necessary to analyse the liquid of ponction to be affirmative.

  11. Intraperitoneal tuberculous abscess: computed tomography features

    Peng; Dong; Jing-Jing; Chen; Xi-Zhen; Wang; Ya-Qin; Wang


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

  12. Medical management of cerebellar abscess: a case report and review of the literature.

    Turner, Ryan C; Dodson, Sean C; Rosen, Charles L


    A large abscess of the posterior fossa often warrants surgical intervention. We report a case of a 50-year-old male presenting with a cerebellar abscess measuring 2.8 cm x 1.6 cm located in the left cerebellar hemisphere at the level of the middle cerebellar peduncle that was treated conservatively and successfully with antibiotics. Therapeutic management options are discussed in regards to this case specifically as well as a review of the literature. This case illustrates the successful medical management of a cerebellar abscess of otogenic origin in an adult, a unique result in terms of abscess size and age of the patient.

  13. Diffuse large B cell lymphoma presenting as a peri-anal abscess.

    Jayasekera, Hasanga; Gorissen, Kym; Francis, Leo; Chow, Carina


    A non-healing peri-anal abscess can be difficult to manage and is often attributed to chronic disease. This case documents a male in his seventh decade who presented with multiple peri-anal collections. The abscess cavity had caused necrosis of the internal sphincter muscles resulting in faecal incontinence. Biopsies were conclusive for diffuse large B-cell lymphoma. A de-functioning colostomy was performed and the patient was initiated on CHOP-R chemotherapy. Anal lymphoma masquerading as a peri-anal abscess is rare. A high degree of suspicion must be maintained for an anal abscess which does not resolve with conservative management.

    Sofia A Santos; Jo(a)o R Deus; Sara CF Alberto; Elsa Cruz; Eduardo Pires; Tomás Figueira; (E)lia Coimbra; José Estevez; Mário Oliveira; Luís Novais


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

  15. A prospective study of USG guided pigtail catheter drainage in management of liver abscess

    Haresh B. Italiya


    Full Text Available Background: Treatment of the liver abscess of any etiology has evolved in the recent years. Percutaneous drainage of liver abscess has been an important advancement in the treatment of pyogenic liver abscesses. Aim: to evaluate and assess response, morbidity and complication rates of percutaneous pig tail catheter drainage in treatment of liver abscess. Methods: During a period of 27 months, 25 patients with liquefied liver abscess and #8805;5x5 cm underwent percutaneous drainage under sonographic guidance. Results: 18 had solitary abscess, while 7 had multiple abscesses. Pigtail catheters of various sizes (10 F or 12 F were introduced in these patients using the Seldinger technique. The volume of pus drained ranged from 150 to 400 ml, while the period of catheter drainage ranged from 6 to 17 days. Complications were minor and included catheter blockage in 2 patients and tract pain in 8 patients. There was no mortality associated with this procedure. This study shows a success rate of 96% (successful treatment in 24 out of 25 patients. Conclusion: Percutaneous catheter drainage of liver abscesses is successful with a low morbidity and mortality and should be the first line of management in liquefied moderate to large sized liver abscesses.

  16. Computed tomography-guided percutaneous catheter drainage of primary and secondary iliopsoas abscesses

    Cantasdemir, M. E-mail:; Kara, B.; Cebi, D.; Selcuk, N.D.; Numan, F


    AIM: To report our experience with computed tomography (CT)-guided percutaneous catheter drainage (PCD) of iliopsoas abscesses. MATERIALS AND METHODS: Twenty-two iliopsoas abscesses in 21 patients (11 women, 10 men) aged between 18 and 66 years (mean 36 years) were treated with PCD. Abdominal CT demonstrated the iliopsoas abscesses, which were definitively determined by Gram staining and aspirate cultures. Twenty of the 22 iliopsoas abscesses were primary and two were secondary. All PCD procedures were performed under local anaesthesia using a single-step trocar technique (n=19) or Seldinger technique (n=3). RESULTS: PCD was an effective treatment in 21 out of the 22 iliopsoas abscesses. Recurrence was seen in three abscesses as minimal residual collections. Two of them resolved spontaneously with anti-tuberculous regimen. One required percutaneous needle aspiration. The procedure failed in a diabetic patient with a secondary abscess, who died due to sepsis. The length of time that catheters remained in place ranged from 21 to 75 days (mean 59.7 days). Complications included catheter dislocation in four abscesses, which required removal of dislocated catheters and indwelling new ones. CONCLUSION: CT-guided PCD is a safe and effective front-line treatment of iliopsoas abscesses. Surgery should be reserved for failure of PCD and presence of contraindications to PCD.

  17. Vesicoovarian Fistula on an Endometriosis Abscessed Cyst


    We report the case of a patient who developed a vesicoovarian fistula on an endometriosis abscessed cyst. The patient presented with an advanced endometriosis stage IV complicated with a right ovarian abscessed cyst of 10 cm. A first coelioscopy with cystectomy was realized. After surgery, a voiding cystography highlighted a fistula between the ovarian abscess and the bladder. A second surgery by median laparotomy was realized with the resection of the right ovarian abscess and the resection ...

    Boyaci, Ahmet; Boyaci, Nurefsan; Tutoglu, Ahmet; Dokumaci, Dilek Sen


    Involvement of the skeletal system is a common complication of brucellosis. However, muscle involvement or paraspinal abscess formation are rare complications. Paraspinal abscess usually develops secondary to spondylitis. A case is reported here of a 33-year-old woman with symptoms of night sweats, fever and low back pain. Rose-Bengal test for brucellosis was positive and Brucella standard tube agglutination test was positive at a titre of 1/160. The diagnosis was made on MRI. The patient was treated with doxycycline and rifampin daily for 16 weeks. On day 14 of treatment, decline was observed in the patient's symptoms. In the presence of inflammatory lower back pain and fever, brucellosis should be considered particularly in the endemic areas. Furthermore, tuberculosis should be remembered in the differential diagnosis when a spinal epidural abscess is determined.

  19. Breast Abscess: A Brief Communication

    Pradipta Das


    Full Text Available Breast infections commonly affect women aged between 18 and 50 years and are categorized as lactational and non-lactational infections. The infection can affect the skin overlying the breast when it can be a primary event or, it may occur secondary to mastitis and/or, secondary to a lesion in the skin. The commoner clinical findings consist of a tender, hard breast mass with erythema of the overlying skin. Needle aspiration yields pus cultures of which yield the infecting microorganisms. In practice, treatment is usually empiric consisting of bed rest, frequent nursing, fluids, Acetaminophen for pain and fever and a course of antibiotics. The other common line of treatment for breast abscess consists of incision and drainage with primary and/or, secondary closure. This brief communication on breast abscess gives an overview of the possible etiologies, clinical signs and symptoms and the treatment lines for breast abscess.

    Full Text Available In spite of a significant decrease in cases of chronic otitis media following the advent of antibiotics, complications of otitis media still represent a challenging situation owing to their high mortality rate. Factors that can cause complications include the level of virulence of the infectious organism, poor resistance of the patient, the presence of chronic systemic diseases and resistance of the infecting organism to antibiotics. The contemporary risk for developing extracranial complications of otitis media is approximately twice that of developing intracranial complications. Inflammation and infection may result in necrosis of the mastoid tip, allowing the pus to track from the medial side of the mastoid process through the incisura digastrica (digastric groove. The pus is prevented from reaching the body surface by the neck musculature, but can track along the fascial planes of the digastric muscle, sternomastoid or trapezius muscles. Pneumatisation of the mastoid process leads to thinning of the bone and is considered an important factor in the development of a trapezius or Bezold’s abscess.

    Swanson, Amy; Lau, Kenneth K; Korman, Tony M; Kornman, Tony; Wallace, Euan M; Polyakov, Alex


    Primary iliacus-psoas muscle abscess formation is very uncommon during pregnancy. We present a case of a primary iliacus-psoas muscle abscess in pregnancy causing back pain with delayed diagnosis and treatment. Understanding the clinical presentation of iliacus-psoas muscle abscess helps with considering it in the differential diagnosis of back pain during pregnancy.

  2. Treatment of inflammatory external root resorption resulting from dental avulsion and pulp necrosis: clinical case report.

    Cunha, Rodrigo Sanches; Abe, Flavia Casale; Araujo, Roberta Aranha; Fregnani, Eduardo Rodrigues; Bueno, Carlos Eduardo da Silveiro


    The aim of this case report was to present a treatment for severe inflammatory external root resorption. The condition developed due to the patient's neglect to seek adequate treatment following replantation of an avulsed maxillary left central incisor. Following diagnosis, treatment consisted of conventional endodontic therapy with calcium hydroxide dressings and definitive filling of the root canal after the resorption was controlled radiographically. A 24-month follow-up showed that the resorption process had stabilized and the patient was free of symptoms. Successful tooth replantation requires following the indicated therapy effectively. Nevertheless, when an inflammatory external root resorption occurs, adequate endodontic treatment to remove the necrotic content and bacteria is required, as is the use of calcium hydroxide dressings.

  5. Good penetration of moxifloxacin into human abscesses.

    Sauermann, Robert; Karch, Rudolf; Kjellsson, Maria C; Feurstein, Thomas; Püspök, Andreas; Langenberger, Herbert; Böhmdorfer, Michaela; Jäger, Walter; Zeitlinger, Markus


    Abscesses are often treated with antibiotics in addition to incision or when incision is unfeasible, but accurate information about antibiotic abscess penetration in humans is missing. This study aimed at evaluating the penetration of moxifloxacin into human abscesses. After administration of a single dose of 400 mg moxifloxacin, drug concentrations were measured in 10 differently located abscesses at incision, and in plasma over 8 h. At incision performed 0.9-4.8 h after administration, moxifloxacin concentrations in abscesses ranged from ≤0.01 to 9.2 mg/l (1.9 ± 3.4 mg/l), indicating pronounced drug accumulation in some abscesses. The degree of abscess penetration could not be explained by covariates like the ratio of surface area to volume or pH of abscesses, or by moxifloxacin plasma concentrations. Concluding, moxifloxacin was detectable in most abscesses and may be a useful antibiotic for this indication. However, antibiotic abscess penetration was highly variable and unpredictable, suggesting surgical abscess incision whenever possible.

  6. Successful Management of a Recurrent Supralevator Abscess: A Case Report

    S. Sanyal


    Full Text Available Anorectal abscesses are commonly encountered in clinical surgical practice. These abscesses require surgical management. Supralevator abscesses are thought to originate either from an ischiorectal or intersphincteric abscess extension or from an intraperitoneal source. These abscesses are quite uncommon and present a difficult surgical problem. We present a case here of a 42-year-old female with a recurrent supralevator abscess requiring multiple surgical procedures for adequate drainage and care of her abscess.

  7. Bacteriology and Antibiotic Susceptibility Pattern of Peitonsillar Abscess

    A Acharya


    Full Text Available INTRODUCTION: Peritonsillar abscess is a common complication of acute tonsillitis. Its management consists of aspiration or surgical drainage followed by appropriate antibiotics. Appropriate antibiotic treatment depends on the common organisms associated with infection and their antibioticsensitivity pattern in local scenario. METHODS: Pus samples aspirated from diagnosed cases of peritonsillar abscess and submitted for culture and sensitivity in last two years were included in this study. Identification of different microorganisms was made on the basis of the microscopic findings, observation of their colony morphology and standard biochemical reactions. Susceptibility pattern to commonly used antibiotics were determined by Clinical Laboratory Standards Institute (CLSI guidelines. RESULTS: Altogether 24 pus samples were included in the study. Positive culture was obtained from 18 samples. Among them one organism was isolated from 13 samples whereas from five samples multiple organisms were isolated. From six samples no organisms could be cultured. Altogether Streptococcus pyogenes was isolated from 12 samples and Staphylococcus aureus from five samples. Other isolated organisms included Haemophlilus influenzae, Pseudomonas aeruginosa, Escherichia coli and Enterococcus species. Penicillin was effective for Streptococcus pyogenes whereas Staphylococcus aureus was resistant to it. Cloxacillin was found to be effective for Staphylococcus aureus. Ciprofloxacin and Ceftazidime were found to be effective for both organisms. CONCLUSIONS: Streptococcus pyogenes and Staphylococcus aureus were more commonly associated with peritonsillar abscess. Streptococcus pyogenes were sensitive to penicillin but all Staphylococcus aureus were resistant to it. This fact should be considered in clinical practice for management of peritonsillar abscess. KEYWORDS: Bacteriology, Peritonsillar abscess, Susceptibility pattern.

  8. Renal abscess after the Fontan procedure: a case report

    Kumar Suresh


    Full Text Available Abstract Introduction The Fontan procedure is an intervention that helps to correct single ventricle physiology. There are many known long-term complications of 'Fontan physiology'. However, the occurrence of renal abscess in such patients has not yet been reported in the literature. The first generation of adults has now undergone the procedure and it is necessary to be aware of the long-term outcomes and complications associated with it. Case presentation We report the case of a 22-year-old South Indian man who had developed a staphylococcal renal abscess against a background of xanthogranulomatous pyelonephritis, nine years after Fontan surgery. He presented to our hospital with a high-grade fever of 25-days duration but with no other symptoms. Physical examination identified costovertebral angle tenderness and pedal edema. An ultrasound scan revealed a mass in his left kidney. The results of a computed tomography scan were consistent with a renal abscess. Despite treatment with the appropriate parenteral antibiotics, there was no change in the size of the abscess and a left nephrectomy was performed as a curative procedure. Conclusions The learning points here are manifold. It is important to be aware of the possibility of renal abscess in a post-procedural patient. The early diagnosis of a septic focus in the kidneymay help to prevent the rare outcome of nephrectomy.

  9. Foreign body ingestion: rare cause of cervical abscess.

    Costa, Liliana; Larangeiro, João; Pinto Moura, Carla; Santos, Margarida


    Foreign body ingestion is a frequent emergency occurrence. Serious complications, although rare, include pharyngooesophageal perforation, aorto-oesophageal fistula and deep neck infection. A retrospective review was performed of all cases of foreign body ingestion requiring hospitalization between 1989 and 2011, in a tertiary Hospital. Cases complicated by deep cervical abscess were selected and their clinical presentation, results of diagnostic exams, therapeutics and clinical evolution are presented. Among a total of 1679 cases, 319 were related to pediatric patients and 1360 to adults. Two cases were reported (0.12%): an adult, 41 years-old, with parapharyngeal abscess subsequent to fishbone ingestion, and a child, 13 months-old, with retropharyngeal abscess consequent to chicken bone ingestion. Complications appeared three and four days after foreign body removal, respectively. In both situations cervical computerized tomography scan with contrast and surgical drainage were accomplished; the child was also submitted to rigid esophagoscopy for residual foreign body removal and closure of the associated pharyngeal laceration. Deep cervical abscesses are an uncommon but possible complication of foreign body ingestion and constitute a diagnostic challenge, particularly in children. Previous oesophageal manipulation by flexible endoscopy may be considered a risk factor for such complication. Imagiological studies proved to be crucial for diagnosis and therapeutic planning. Although a rare complication, given a recent history of foreign body ingestion/removal and the presence of compatible symptoms, cervical abscesses should be taken into account, highlighting their potential morbimortality in the absence of an appropriate therapeutic approach.

    Lee, Jong Tae; Kwon, Tae Hee; Yoo, Hyung Sik; Suh, Jung Ho [Yonsei University College of Medicine, Seoul (Korea, Republic of); Lee, Young Ho [Cheil General Hospital, Seoul (Korea, Republic of)


    Percutaneous catheter drainage has been reported to be an effective method in the management of selected patients with abscess and fluid collection. Its high success rate and relatively low complications make the procedure an alternative to surgery in the individual cases. During past two years percutaneous catheter drainage in 25 patients with intraabdominal abscesses and fluid collection was performed at the Department of Radiology, Yonsei University College of medicine. Here the technique and author's results were summarized. 1. The total 25 patients who had percutaneous catheter drainage are 10 liver abscesses, 3 subphrenic, one subhepatic, 4 renal and perirenal, 2 pelvic, one psoas, one anterior pararenal fluid from acute pancreatitis, one pancreas pseudocyst and 2 malignant tumor necrosis. 2. The modified Seldinger technique used for all cases of abscess and fluid drainage under guidance of ultrasound scan. The used catheters were 10F. Pigtail and 14F. Malecot (Cook c/o) catheters. 3. The abscesses and fluid of 17 patients among 25 were cured by the percutaneous catheter drainage and 4 patients were clinically improved. The catheter drainage was failed in 2 patients and 3 complication were developed. 4. The success rate of this procedure was 91.3%, failure rate was 8.7% and complication rate was 12%.

  11. Giant retroperitoneal abscess following necrotizing pancreatitis treated with internal drainage

    Ludmil Marinov Veltchev; Manol Anastasov Kalniev


    BACKGROUND: Retroperitoneal abscess is a dangerous complication of the inflammatory process in organs. The pancreas reacts by enzymatic autodigestion and inflammation to external and internal factors: alcohol abuse, trauma, biliary stones, and viral infections. Chronic pancreatitis and formation of pseudocysts are late complications. The diffuse spread of pancreatic inflammation may form a retroperitoneal phlegmon. A better outcome is the limitation of the process by capsule formation-retroperitoneal abscess. METHODS: A 62-year-old man, with a history of alcohol abuse, was admitted for intermittent abdominal pain, fever, and significant weight loss. Previous medical consultations (laboratory tests, US, CT) confirmed chronic pancreatitis with pseudocyst formation. A new CT depicted a giant retroperitoneal abscess. RESULTS: After preoperative preparation with antibiotics, laparotomy and internal drainage-longitudinal cystoje-junostomy with Roux-en-Y loop were performed. At the 8th postoperative day the patient was in good condition. CONCLUSIONS: Giant retroperitoneal abscess is a dangerous pathology with significant mortality and morbidity. Diagnosis strongly necessitates operative intervention in order to evacuate and drain the space. These conditions include one internal drainage (in the GI tract) with the stomach, duodenum, or jejunum, which does not cause early and late GI discomfort and will gradually liquidate the cavity. We propose internal drainage with Roux-en-Y jejunal loop as the only method for accomplishing these conditions in cases of giant retroperitoneal abscesses.

  12. Sodium hypochlorite accident resulting in life-threatening airway obstruction during root canal treatment: a case report

    Full Text Available Maisa O Al-Sebaei,1 Omar A Halabi,2 Ibrahim E El-Hakim3 1Department of Oral and Maxillofacial Surgery, King Abdulaziz University – Faculty of Dentistry, Jeddah, Kingdom of Saudi Arabia; 2Saudi Board of Oral and Maxillofacial Surgery, Al-Noor Specialist Hospital, Makkah, Kingdom of Saudi Arabia; 3Department of Oral and Maxillofacial Surgery, Riyadh Colleges of Dentistry and Pharmacy, Riyadh, Kingdom of Saudi Arabia Aim: This case report describes a serious and life-threatening complication of the use of sodium hypochlorite as an irrigation solution in root canal therapy. Summary: This case report describes a hypochlorite accident that occurred in a healthy 42-year-old female who was undergoing routine root canal therapy for the lower right central incisor (tooth #41. After approximately 1 hour of irrigation with 3% sodium hypochlorite (for a total of 12 cc, the patient complained of severe pain and burning in the lip. The swelling progressed over the next 8 hours to involve the sublingual and submental fascial spaces with elevation of the tongue and resultant upper airway obstruction. The patient was intubated and remained on mechanical ventilation for 3 days. She recovered without any skin necrosis or nerve deficits. Key learning points: This case report highlights the importance of carefully performing root canal irrigation with sodium hypochlorite to avoid complications. Careful injection without pressure, the use of proper rubber dam isolation, and the use of the endodontic needle are necessary to avoid this type of complication. Although it is a safe root canal irrigation solution, its use may lead to life-threatening complications. Early recognition and management of the untoward effects of sodium hypochlorite are vital for the patient's safety.

  14. Sub-Linear Root Detection, and New Hardness Results, for Sparse Polynomials Over Finite Fields

    Bi, Jingguo; Rojas, J Maurice


    We present a deterministic 2^O(t)q^{(t-2)(t-1)+o(1)} algorithm to decide whether a univariate polynomial f, with exactly t monomial terms and degree root in F_q. A corollary of our method --- the first with complexity sub-linear in q when t is fixed --- is that the nonzero roots in F_q can be partitioned into at most 2 \\sqrt{t-1} q^{(t-2)(t-1)} cosets of two subgroups S_1,S_2 of F^*_q, with S_1 in S_2. Another corollary is the first deterministic sub-linear algorithm for detecting common degree one factors of k-tuples of t-nomials in F_q[x] when k and t are fixed. When t is not fixed we show that each of the following problems is NP-hard with respect to BPP-reductions, even when p is prime: (1) detecting roots in F_p for f, (2) deciding whether the square of a degree one polynomial in F_p[x] divides f, (3) deciding whether the discriminant of f vanishes, (4) deciding whether the gcd of two t-nomials in F_p[x] has positive degree. Finally, we prove that if the complexity of root detection is sub-l...

[Department of Radiology, Adelaide and Meath Hospital, Tallaght, Dublin 24 (Ireland)]. E-mail:


    Objectives: To determine the utility of percutaneous computed tomography (CT) guided drainage of abscesses formed secondary to retained appendicoliths. Materials and methods: A retrospective review was conducted over a 5-year period to identify patients who underwent CT guided drainage of abscesses related to retained appendicoliths. Inclusion criteria were a history of prior proven appendicitis treated by laparoscopic appendicectomy, identification of a post-operative abscess related to a visualised retained appendicolith and initial treatment by CT guided drainage. Data regarding initial technical success as well as long-term outcome was recorded in each case. Results: In total, five patients were identified who underwent CT guided abscess drainage related to retained appendicoliths. There were three males and two females (age range 12-54 years). Initial drainage under CT guidance was technically successful in all cases with successful catheter placement and resolution of the abscess cavity. In all five cases however, there was recurrence of abscess formation following catheter removal. In one case, a second attempt with CT guided drainage was performed. Again this was initially successful with abscess recurrence following catheter removal. In all five cases, formal surgical drainage with removal of retained appendicolith resulted in a successful outcome. Conclusion: CT guided percutaneous drainage of intra abdominal abscess secondary to retained appendicoliths is only successful in the short term. Formal surgical drainage and removal of the appendicolith is required for long-term success.

Coll. of Medicine, Seoul (Korea, Republic of)


    Background: Differentiation of postoperative neck abscess from non-infected fluid is important because the treatment is different. Purpose: To determine specific CT findings that might help to differentiate abscesses from non-infected fluid collections in the postoperative neck. Material and Methods: We retrospectively reviewed CT scans of 50 patients (43 men and 7 women; mean age, 62.5 {+-} 8.9 years) who had postoperative fluid collections in the neck (26 abscesses and 24 non-infected fluid collections). Diagnosis of an abscess was determined by a positive bacteria culture from the fluid collection. Diagnoses were correlated with the following CT findings: anatomic spaces involved, the maximum transverse diameter, margin, attenuation, rim enhancement, gas bubbles, and manifestations of soft tissue adjacent to a fluid collection. Results: Rim enhancement pattern and soft tissue manifestations showed significant differences between abscess and non-infected fluid. The reliable CT findings for abscess were: (i) rim enhancement > 50% of the circumference, 54% sensitive, 71% specific, and 62% accurate; and (ii) severe soft tissue manifestations, 39% sensitive, 92% specific, and 64% accurate. There were no significant differences in the anatomic spaces involved, the maximum transverse diameter, margin, attenuation, and gas bubbles between abscess and non-infected fluid. Conclusion: CT findings that may help differentiate postoperative neck abscess from non-infected fluid were rim enhancement > 50% of the circumference and severe soft tissue manifestations.

    Background. Reports on CT-guided percutaneous drainage within the intervertebral space for pyogenic spondylodiscitis with a secondary psoas abscess are limited. Purpose. To evaluate CT-guided percutaneous drainage within the intervertebral space for pyogenic spondylodiscitis and a secondary psoas abscess in which the two sites appear to communicate. Material and Methods. Eight patients with pyogenic spondylodiscitis and a secondary psoas abscess showing communication with the intradiscal abscess underwent CT-guided percutaneous drainage within the intervertebral space. The clinical outcome was retrospectively assessed. Results. An 8-French pigtail catheter within the intervertebral space was successfully placed in all patients. Seven patients responded well to this treatment. The one remaining patient who had developed septic shock before the procedure died on the following day. The mean duration of drainage was 32 days (13-70 days). Only one patient with persistent back pain underwent surgery for stabilization of the spine after the improvement of inflammation. Among seven patients responding well, long-term follow-up (91-801 days, mean 292 days) was conducted in six patients excluding one patient who died of asphyxiation due to aspiration unrelated to the procedure within 30 days after the procedure. In these six patients, no recurrence of either pyogenic spondylodiscitis or the psoas abscess was noted. Conclusion. CT-guided percutaneous drainage within the intervertebral space can be effective for patients with pyogenic spondylodiscitis and a secondary psoas abscess if the psoas abscess communicates with the intradiscal abscess

  20. Presacral abscess as a rare complication of sacral nerve stimulator implantation.

    Gumber, A; Ayyar, S; Varia, H; Pettit, S


    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.

  1. Intracavitary urokinase in the treatment of multiloculated liver abscess : a case report

    Lee, Jeong Min; Lee, Mi Suk; Lee, Jin Hee; Ym, Seong Hee [Namwon Medical Center, Namwon (Korea, Republic of); Kim, Chong Soo; Han, Young Min; Choi, Ki Chul [Chonbuk National Univ. College of Medicine, Chonju (Korea, Republic of)


    Radiologically-guided percutaneous abscess drainage has been preferred as a therapeutic modality for hepatic abscesses, though where these have been septated or multilocular, its success rate has often been low. The results of several clinical and in vitro studies have recently suggested that in difficult cases, where abscesses occur in the peritoneal cavity and retroperitoneum, or multiloculated empyema of the thorax, urokinase may be useful. To our knowledge, however, there has been only one report of a case of liver abscess in which intracavitary urokinase was administered. The authors therefore report a case of multiseptated hepatic abscess occuring in a 53-year-man. Conventional percutaneous tube drainage failed, but the use of transcatheter intracavitary urokinase was successful. Diagnosis and continuing assessment involved a combination of ultrasound and CT scanning.

  2. Drainage or Packing of the Sella? Transsphenoidal Surgery for Primary Pituitary Abscess: Report of Two Cases

    Soichi Oya


    Full Text Available The detailed surgical procedure of the transsphenoidal surgery for pituitary abscess has scarcely been described previously because it is a very rare clinical entity. The authors reported two cases of primary pituitary abscess. In case 1, the anterior wall of the sella turcica was reconstructed with the vomer bone after irrigating the abscess cavity, but the sella was not packed by fat for fear of the persistent infection by devascularized tissues. This led to the postoperative meningocele, the cerebrospinal fluid leak, and bacterial meningitis despite the successful abscess drainage. In case 2, tight sellar packing and reconstruction of the sellar wall were performed to avoid these postoperative complications, which resulted in complete drainage and uneventful postoperative course. Although accumulation of more cases is obviously needed to establish the definitive surgical technique in pituitary abscess surgery, our experience might suggest that packing of the sella is not impeditive for postoperative sufficient drainage.

    microorganisms most commonly found were Streptococcus viridans in 17 (26.2% patients, Enterococcus sp in 6 (7.7%, and Staphylococcus aureus in 9 (13.8%. Nine patients presented PR interval longer than 0.20 mseg in the pre operative eletrocardiography. The indications for operation were prosthetic valve endocarditis in 46 cases (70.8%, heart failure in 9 (13.8%, failure in clinical treatment in 5 (7.7%, embolism in 2 (3.1%, fungal endocarditis in 1 (1.5%, and others in 2 (3.1 %. The immediate mortality was 17 (26.2% patients. There were 9 (13.8% late deaths; of these, 5 presented a new episode of bacterial endocarditis. Thirty seven (86% patients were in class I (NYHA, 4 in FC II, and 2 in FC III in the late postoperative period, with a mean followup of 5.3 years.These results show that the bacterial endocarditis associated with abscess in the valvular ring is a high risk pathology, the treatment is surgical, and the most common late complication is the reinfection.

  4. Chronic Calcific Pancreatitis Presenting as an Isolated Left Perinephric Abscess: A Case Report and Review of the Literature

    Ragesh Babu Thandassery


    Full Text Available Context Acute and chronic pancreatitis may present with pseudocysts in atypical locations. Activated pancreatic enzymes track along anatomic fascial planes causing digestion of the surrounding tissues and resulting in distant pseudocysts. Pseudocysts at atypical locations pose significant diagnostic as well as therapeutic challenges. Case report We report an unusual presentation of a pancreatic pseudocyst in a young male who presented with a left perinephric abscess. Percutaneous drainage was not successful in resolving the abscess and he was subsequently diagnosed as having chronic pancreatitis together with a left perinephric abscess. Needle knife sphincterotomy of the ampulla of Vater resulted in the gradual resolution of the abscess. Conclusion We report a rare presentation of chronic pancreatitis with a perinephric abscess and its non-surgical management. This case report indicates that any patient presenting with a perinephric abscess of unknown etiology not responding to conventional treatment modalities should be investigated for underlying pancreatitis.

    Full Text Available The diagnosis of hepatocellular carcinoma (HCC became easier in relation to the improved radiological examinations; however, the neoplasm may occur under atypical presentations mimicking other benign or malignant processes. Multicystic HCC mimicking a liver abscess associated with septic-type fever and leukocytosis is rare, has a poor prognosis, and poses diagnostic and therapeutic dilemmas. We present the case of an 80-year-old patient, who presented with fever, leukocytosis, and large cystic masses involving right and left lobes of the liver initially considered abscesses and finally diagnosed as HCC after open drainage and liver biopsy. Although the patient died on the tenth postoperative day due to pulmonary oedema, the authors emphasize the high index of suspicion needed in the diagnosis of this unusual presentation of HCC.

  6. Epidemiology, Clinical Features and Outcome of Liver Abscess: A single Reference Center Experience in Qatar

    Mushtak Talib Abbas


    Full Text Available Objective: To describe the etiology, clinical presentation, management and outcome of liver abscess in adult patients admitted at Hamad general hospital, Qatar. Methods: A cross sectional study was conducted to involve all adult patients who sequentially encountered episodes of liver abscess during the period from January 1, 2009, to December 31, 2010. Blood cultures were drawn from all patients in the first 24 hours after admission. In addition, all patients had stool examinations and indirect Hemagglutination test for Entameba histolytica. Aspiration of abscess was done under CT guidance and aspirated pus was sent for gram stain and culture. Results: In total, 67 patients were admitted with liver abscess; 56 patients with pyogenic liver abscess and 11 with amebic liver abscess. There were 61 (91% males and six (9% females and their mean age was 47.4 ± 18.5 years. Fever, abdominal pain and vomiting were the commonest presenting features. Of the 56 pyogenic liver abscess patients, four discharged against medical advice and seven refused all invasive procedures and were treated with antibiotics for six weeks. The remaining 44 (79% patients were treated with antibiotics and one or more invasive procedures, while one patient was treated surgically. The commonest organism isolated was Klebseilla pneumonia found in 21 patients (38%. The mean duration of hospitalization was 13.6 ± 8.1 days; the mean duration of antibiotic therapy was 34.7 ± 40.6 days, and one patient died. In contrast, all amebic liver abscess patients underwent ultrasound guided aspiration and showed good response to metronidazole treatment. Their mean duration of hospitalization was 7.7 ± 4.1 days, mean duration of therapy was 11.8 ± 2.1 days, and all patients were cured. Conclusion: Pyogenic liver abscess was more common than amebic liver abscess with Klebseilla pneumonia being the commonest organism. With good medical measures and early drainage of liver abscess, surgical

    Enver Zerem; Jacob Bergsland


    AIM: To analyze the results of ultrasound guided percutaneous needle aspiration (PNA) and percutaneous catheter drainage (PCD) in the treatment of splenic abscess.METHODS: Thirty-six patients (14 females and 22 males, with an average age of 54.1 ± 14.1 years) with splenic abscess were treated with ultrasound guided PNA and/or PCD. Patients with splenic abscess < 50 mm in diameter were initially treated by PNA and those with abscess ≥ 50 mm and bilocular abscesses were initially treated by an 8-French catheter drainage. The clinical characteristics, underlying diseases, organism spectra,therapeutic methods, and morality rates were analyzed.RESULTS: Twenty-seven patients had unilocular and 9 bilocular abscess. PNA was performed in 19 patients (52.8%), and 8 of them (42.1%) required PCD because of recurrence of abscess. In 17 patients (47.2%), PCD was performed initially. PCD was performed twice in six patients and three times in two. PNA was definitive treatment for 10 and PCD for 21 patients. One patient with PCD was referred for splenectomy, with successful outcome. In all 4 deceased patients, malignancy was the underlying condition. Twenty-one patients (58.3%)underwent 33 surgical interventions on abdomen before treatment. Cultures were positive in 30 patients (83.3%).Gram-negative bacillus predominated (46.7%). There were no complications related to the procedure.CONCLUSION: Percutaneous treatmnet of splenic abscess is an effective alternative to surgery, allowing preservation of the spleen. This treatment is especially indicative for the patients in critical condition postoperatively. We recommend PNA as primary treatment for splenic abscesses < 50 mm, and PCD for those ≥ 50 mm in diameter and for bilocular abscesses.

  8. How the anal gland orifice could be found in anal abscess operations

    Shahram Paydar


    Full Text Available Background: On an average 30-50% of patients who undergo incision and drainage (I and D of anal abscess will develop recurrence or fistula formation. It is claimed that finding the internal orifice of anal abscess to distract the corresponding anal gland duct; will decline the rate of future anal fistula. Surgeons supporting I and D alone claim that finding the internal opening is hazardous. This study is conducted to assess short-term results of optional method to manage patients with anal abscess and fitula-in-ano at the same time. Materials and Methods: In this cross-sectional descriptive study 49 from 77 patients with anal abscess whose internal orifice was not identified by pressing on the abscess, diluted hydrogen peroxide (2% and methylene blue was injected into the abscess cavity and the anal canal was inspected to find out the internal opening. Once the opening was distinguished, an incision was given from the anal verge to the internal opening. Results: The internal orifice was identified in 44 out of 49 patients (90% who underwent this new technique. Up to 18 months during follow-up, only 2.5% of patients with primary fistulotomy developed fistula on the site of a previous abscess. Conclusion: Conventional method to seek the internal orifice of anal abscesses is successful in about one-third of cases. By applying this new technique, surgeons would properly find the internal opening in >90% of patients. Needless to say, safe identification of the anal gland orifice in anal abscess disease best helps surgeons to do primary fistulotomy and in turn it would significantly decrease the rate of recurrence in anal abscess and fistula formation.

  9. Abdominal wall abscess secondary to spontaneous rupture of pyogenic liver abscess

    Maurizio Zizzo


    Conclusion: 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.

  10. Klebsiella Pneumoniae Multi-organ Abscesses not Accompanied by Liver Abscesses: A Case Report

    Kim, Sung Taek; Park, Chul Hi; Hwang, Ho Kyung; Lee, Mi Ran; Lee, Dong Hoon; Kim, Min Ji [Dept. of Radiology, Seoul Medical Center, Seoul (Korea, Republic of)


    A Klebsiella pneumoniae infection has a tendency to spread to multiple organs. It is most commonly seen in patients with liver abscesses, but infection in more than three organs without liver abscesses is unusual. We report one case of a K. pneumoniae infection that presented acute pyelonephritis with left perirenal, anterior pararenal, left psoas, and prostate abscesses without liver abscesses in a diabetic patient. With effective antibiotics and ultrasound-guided percutaneous drainage, the patient recovered without significant sequelae.

    Tuberculous retropharyngeal abscess is a rare presentation. It is present in adults usually due to involvement of cervical spine by tuberculosis. Retropharyngeal space usually gets involved in children due to pyogenic organisms or secondary to trauma. Here is a case of tuberculous retropharyngeal abscess in an adult female, with pulmonary tuberculosis. The patient was not having tuberculous involvement of cervical spine and was managed surgically by aspirating the retropharyngeal abscess transorally and AKT Category I.

  12. Behçet's disease complicated by multiple aseptic abscesses of the liver and spleen.

    Maeshima, Keisuke; Ishii, Koji; Inoue, Megumi; Himeno, Katsuro; Seike, Masataka


    Aseptic abscesses are an emergent entity and have been described in inflammatory bowel disease, especially in Crohn's disease, and in other diseases. However, aseptic abscesses associated with Behçet's disease are extremely rare. We report a Japanese male diagnosed with an incomplete type of Behçet's disease who developed multiple aseptic abscesses of the spleen and liver. In 2002, the spleen abscesses were accompanied by paroxysmal oral aphthous ulcers and erythema nodosum. As the patient's response to antibiotic treatment was inadequate, a splenectomy was performed. Severe inflammatory cell infiltration, largely of polymorphonuclear neutrophils, was observed without evidence of bacterial or fungal growth. Although the patient had no history of ocular symptoms or genital ulcers, a diagnosis of incomplete Behçet's disease was made according to the Japanese diagnostic criteria because of the presence of paroxysmal arthritis and epididymitis since 2002. In 2005, multiple liver abscesses developed with right hypochondrial pain and seemed to be attributed to Behçet's disease because the abscesses yielded negative results during a microbiologic investigation and failed to go into remission under antibiotic therapy. Oral prednisone (15 mg/d) was started in May 2006, and the abscesses dramatically disappeared 4 wk after treatment. Although the patient had a relapse of the liver abscesses in association with the tapering of prednisone, the augmentation of prednisone dosage yielded a response. The abscesses of the liver and spleen were strongly suggested to be attributed to Behçet's disease. Clinician should be aware of the existence of aseptic abscesses as uncommon manifestations of Behçet's disease.

  13. Left Colon Diverticulitis Presenting as Perforated Lumbar Abscess: A Case Report and Review of the Current Literature

    Daniel Paramythiotis


    Full Text Available Diverticular perforation is a common complication of diverticulitis and can lead to the creation of abscesses. The presence of such abscesses on the abdominal wall is rare and can lead to misdiagnosis. We present the case of a patient with abdominal pain and the formation of a large left lumbar abscess due to perforation of a diverticulum of the left colon and our surgical treatment of choice with favorable results.

  14. Basidiobolus: An unusual cause of lung abscess

    Chetambath Ravindran


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

  15. Vesicoovarian Fistula on an Endometriosis Abscessed Cyst

    C. Tran


    Full Text Available We report the case of a patient who developed a vesicoovarian fistula on an endometriosis abscessed cyst. The patient presented with an advanced endometriosis stage IV complicated with a right ovarian abscessed cyst of 10 cm. A first coelioscopy with cystectomy was realized. After surgery, a voiding cystography highlighted a fistula between the ovarian abscess and the bladder. A second surgery by median laparotomy was realized with the resection of the right ovarian abscess and the resection of vesical fistula.

  16. Non-interventional management of splenic abscess

    Saket Kumar


    Full Text Available Splenic abscess is not an uncommon entity in tropics. In Indian subcontinent, where the incidence of enteric fever is high, abscess formation in spleen is frequently seen in clinical practice. In view of immunological functions, splenic preservation is preferred over splenectomy, especially in children and young adults. Medical management with antibiotics alone is considered inadequate for management of splenic abscess. Hereby, we report an unusual case of complete resolution of a florid splenic abscess with antibiotics alone without the need for any invasive intervention.

  17. Cerebral Abscess Potentially of Odontogenic Origin

    Marouene Ben Hadj Hassine


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

    The report summarizes results of papers and discussions dealing with effects of air pollutants on growth of roots and mycorrhizas. The ratio of calcium and aluminium and its influence on the mentioned parameters is explained. Comparing experiments with trees of different damage degree were carried out to investigate the effects of liming. Changes of nutrient content, of physiology and morphology and of the dominance of mycorrhiza-species could be found.

  20. Mutualism-parasitism paradigm synthesized from results of root-endophyte models.

    Mandyam, Keerthi G; Jumpponen, Ari


    Plant tissues host a variety of fungi. One important group is the dark septate endophytes (DSEs) that colonize plant roots and form characteristic intracellular structures - melanized hyphae and microsclerotia. The DSE associations are common and frequently observed in various biomes and plant taxa. Reviews suggest that the proportion of plant species colonized by DSE equal that colonized by AM and microscopic studies show that the proportion of the root system colonized by fungi DSE can equal, or even exceed, the colonization by AM fungi. Despite the high frequency and suspected ecological importance, the effects of DSE colonization on plant growth and performance have remained unclear. Here, we draw from over a decade of experimentation with the obscure DSE symbiosis and synthesize across large bodies of published and unpublished data from Arabidopsis thaliana and Allium porrum model systems as well as from experiments that use native plants to better resolve the host responses to DSE colonization. The data indicate similar distribution of host responses in model and native plant studies, validating the use of model plants for tractable dissection of DSE symbioses. The available data also permit empirical testing of the environmental modulation of host responses to DSE colonization and refining the "mutualism-parasitism-continuum" paradigm for DSE symbioses. These data highlight the context dependency of the DSE symbioses: not only plant species but also ecotypes vary in their responses to populations of conspecific DSE fungi - environmental conditions further shift the host responses similar to those predicted based on the mutualism-parasitism-continuum paradigm. The model systems provide several established avenues of inquiry that permit more detailed molecular and functional dissection of fungal endophyte symbioses, identifying thus likely mechanisms that may underlie the observed host responses to endophyte colonization.

  2. Medicolegal cases for spinal epidural hematoma and spinal epidural abscess.

    French, Keisha L; Daniels, Eldra W; Ahn, Uri M; Ahn, Nicholas U


    Spinal epidural hematoma and spinal epidural abscess are rare surgical emergencies resulting in significant neurologic deficits. Making the diagnosis for spinal epidural hematoma and spinal epidural abscess can be challenging; however, a delay in recognition and treatment can be devastating. The objective of this retrospective analysis study was to identify risk factors for an adverse outcome for the provider. The LexisNexis Academic legal search database was used to identify a total of 19 cases of spinal epidural hematoma and spinal epidural abscess filed against medical providers. Outcome data on trial verdicts, age, sex, initial site of injury, time to consultation, time to appropriate imaging studies, time to surgery, and whether a rectal examination was performed or not were recorded. The results demonstrated a significant association between time to surgery more than 48 hours and an unfavorable verdict for the provider. The degree of permanent neurologic impairment did not appear to affect the verdicts. Fifty-eight percent of the cases did not present with an initial deficit, including loss of bowel or bladder control. All medical professionals must maintain a high level of suspicion and act quickly. Physicians who are able to identify early clinical features, appropriately image, and treat within a 48 hour time frame have demonstrated a more favorable medicolegal outcome compared with their counterparts in filed lawsuits for spinal epidural hematoma and spinal epidural abscess cases.

    Wesson, C M; Gale, T M


    definitely be incriminated as causative. Four were associated with first molar apicectomy and four with second molar apicectomy. Molar apicectomy with amalgam root-end filling attracts an overall 'complete healing' rate at 5 years of 57%, the results being best with mandibular first molars and worst with mandibular second molars. The prognosis is also better where there is 'good' initial orthograde root filling, an associated radicular cyst as compared with granulomatous change and where the buccal sulcus is deep rather than shallow. It is worse when orthograde root filling is absent and when there is disease in the furcation. 'Complete healing' at 1 year can be expected to be maintained at 5 years in 75% of cases. The commonest site of subsequent periradicular rarefaction seems to be 'apical' whilst failure at the furcation is probably comparatively rare. There is a threefold increase in the occurrence of permanent lower lip sensory impairment following second molar surgery in comparison with first molar surgery, the overall incidence being 1%.

  4. Otogenic brain abscess: A rising trend of cerebellar abscess an institutional study

    Rupam Borgohain


    Full Text Available Chronic inflammation of the middle ear is the most frequent cause of otogenic complications. Meningitis is the most frequent intracranial complications, followed by otogenic brain abscess in neglected otitis media. Although temporal lobe abscesses are more common than cerebellar abscesses, the converse was found to be true in our series of 17 cases. 16 cases of cerebellar abscess and 1 case of temporal lobe abscess were reported as a complication of chronic otitis media (COM. In our group of patients, otogenic brain abscesses were more frequent in male patients of age group 5–20 years with mean age of 14 years. Diagnostic procedure included history, clinical, otorhinolaryngological examination, audiological, microbiological, neurological, ophthalmological, and radiological examinations. The treatment included primary neurosurgical approach (abscess drainage followed by radical otosurgical treatment.

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

  6. Brain abscess due to Aggregatibacter aphrophilus and Bacteroides uniformis.

    Bogdan, Maja; Zujić Atalić, Vlasta; Hećimović, Ivan; Vuković, Dubravka


    The aim of this report was to describe the occurrence of a bacterial brain abscess in a healthy individual, without any predisposing condition. A thirteen-year old boy was admitted to the Department of Neurosurgery after the onset of vomiting, headache and dizziness. A neurological deficit was detected during the physical examination so urgent magnetic resonance imaging of the brain was performed, revealing an intrahemispheric, right positioned solitary expansive mass with ring enhancement. Purulent material was obtained during osteoplastic craniotomy with total extirpation of the brain abscess. Aggregatibacter aphrophilus and Bacteroides uniformis were isolated. The patient's general condition improved and the neurological deficit subsided as a result of the prompt recognition and treatment of this life threatening condition. To achieve a favourable clinical outcome, prompt recognition and surgical treatment of a brain abscess are of primary importance,followed by administration of appropriate antimicrobial therapy. To our best knowledge, this is the first report of this combination of microorganisms as the cause of a brain abscess. Copyright © 2015 by Academy of Sciences and Arts of Bosnia and Herzegovina.

  7. Multidrug resistant citrobacter: an unusual cause of liver abscess.

    Kumar, Prabhat; Ghosh, Soumik; Rath, Deepak; Gadpayle, A K


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

  16. Brain injury due to anaphylactic shock as a result of formocresol used during root canal treatment.

    Ding, Y-J; Song, H; Liu, J-H; Wang, G-H


    Formocresol is still used in many parts of the world despite concerns over its toxicity. A case of a 45-year-old women who experienced brain injury after an analyphlactic reaction to formocresol is presented. During routine root canal treatment, the patient experienced nausea and vomiting after formocresol was used as an antibacterial agent in the pulp chamber. The procedure was discontinued and the symptoms resolved. Four days later, the treatment was continued by a different dentist, and the patient developed anaphylactic shock within 10 min of placement of a formocresol-soaked cotton pellet. She received emergency medical treatment and magnetic resonance imaging (MRI) revealed brain injury characterized by swelling of the gyrus in the cerebral watershed territory of the left parietal-occipital lobe. The patient subsequently made a full recovery after supportive treatment. A type-I allergic reaction can be induced by formocresol. The reasons for the brain injury are thought to be cerebral hypoxia, which was induced by the anaphylactic shock and/or cerebral parenchymal oedema. All dentists should be aware of the risks involved in the use of formocresol and avoid using materials containing formocresol and related agents. © 2013 International Endodontic Journal.

  17. The frequency of dental abscesses increases in periods of low barometric pressure.

    Seemann, Rudolf; Svabik, Otto; Orlik, Alexander; Figl, Michael; Fischer, Michael B; Schicho, Kurt; Wutzl, Arno; Forster, Johannes; Jesch, Philip; Perisanidis, Christos; Undt, Gerhard; Millesi, Werner


    Bioclimatic conditions are thought to have an impact on the frequency of dental abscesses but previous studies have suffered from small patient cohorts, methodological obstacles, and restriction to a single site resulting in limited geographic and meteorological variability. The aim of the present study was to investigate the influence of environmental temperature and barometric pressure on the frequency of dental abscesses. Three maxillofacial and two dental clinics in Vienna retrospectively provided a total of 19,218 patients with dentoalveolar abscesses who were treated by intraoral incision between 1998 and 2011. Daily records from six local meteorological stations were consulted to assess daily meteorological parameters. Univariate and multivariate hurdle count regression models were fitted to estimate the effect of daily average barometric pressure and temperature on registered abscess frequencies. Temporal confounders causing variance of the observed abscess frequencies - such as weekday, business day, and month - were taken into consideration. On days of low barometric pressure a significant rise in dental abscess frequency was observed, even when adjusting for confounders. Environmental temperature, in contrast, did not show any effect. In conclusion, bioclimatic conditions affect health as low barometric pressure increases the number of patients with dental abscesses.

  18. Giant liver abscess due to almost asymptomatic common bile duct stone

    Čolović Radoje B.


    Full Text Available Solitary pyogenic liver abscess is usually caused by a meta-static infection through the portal blood flow or through the hepatic arterial blood flow from extra-abdominal pyogenic foci. Besides, it may be the result of local inflammatory diseases, such as cholecystitis, hydatid cyst, haematomas particularly with retained foreign bodies, etc. Suppurative cholangitis usually causes multiple pyogenic liver abscesses. Solitary pyogenic abscess is rarely caused by cholangitis, but practically always by suppurative cholangitis. Giant pyogenic liver abscess due to asymptomatic or mild cholangitis is a rarity. We present on a 63 year old man who developed a giant solitary pyogenic liver abscess in whom no other possible cause could be found or anticipated except practically almost asymptomatic choledocholithiasis accompanied with mild elevation of bilirubin content alkaline phosphatase and gamma-GT. The patient was successfully treated operatively. Over 1800 ml. of pus was aspirated from the abscess cavity. Operative cholangiography performed in spite of the absence of gall bladder stones undilated and noninflamed common bile duct stone showed a small nonobstructing distal common bile duct stone. The duct was not dilated, the bile was clear and there were no signs of cholangitis in the inside of the common bile duct. Cholecystectomy and abscess cavity drainage led to uneventful recovery. The patient has been symptom-free for more than 3.5 years.

    In order to identify the causative factors of ring abscess, which is the characteristic feature of pseudomonal keratitis, pseudomonal endotoxin, exotoxin A, and elastase were each separately injected into guinea pig cornea. There was no formation of ring abscess. Injection of living Pseudomonas aeruginosa strains IFO3455 and Takamatsu which produce all three molecules, clearly induced ring abscess. In contrast, when heat-killed bacteria strain IFO3455 or living bacteria of the non-elastase-producing strain PA103 were injected, ring abscess was not induced. Furthermore, when living bacteria strain IFO3455 were injected with anti-elastase antibody or a protease inhibitor, ovomacroglobulin, ring abscess formation was significantly inhibited. Histological examination demonstrated that the ring abscess was a dense accumulation and aggregation of polymorphonuclear leukocytes (PMN) with debris of cells and lamellae in the deep stroma at the corneal margins, suggesting prevention of PMN migration to the central lesion. The presence of anti-elastase antibody or a specific elastase inhibitor facilitated PMN migration towards living bacteria strain IFO3455 in an in vitro model. These results indicate that pseudomonal elastase is a necessary but not sufficient factor in the formation of ring abscess in pseudomonal keratitis.

    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.

    Here, we report brain abscess due to Fusobacterium necrophorum (F. necrophorum) in a 78-year-old healthy man. He developed convulsion and did not have any signs of meningitis. Although the brain magnetic resonance imaging findings of the left occipital lobe were typical of a brain abscess, his cerebrospinal fluid examination revealed only slight pleocytosis and mild increase in protein levels. Thus, it was difficult to rule out the possibility of metastatic brain tumor; the patient's condition was provisionally diagnosed as symptomatic epilepsy secondary to brain abscess. His convulsion disappeared soon after administration of antiepileptic, antibacterial, and steroid agents. A craniotomy was performed to evacuate the abscess, and F. necrophorum was identified by culturing the abscess contents. After the operation, he was treated with appropriate antibacterial agents, which resulted in resolution of the brain abscess. Although Fusobacterium species are gram-negative anaerobic bacilli commensal of the human oropharynx, we need to recognize that Fusobacterium species can be a primary pathogen causing brain abscesses and may leave residual neurological sequelae without early appropriate treatment.

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

    Rahav, Galiya; Hanoch, Josef; Shimonovitz, Shlomo; Yagel, Simcha; Laufer, Neri


    Background: Increasing reports of intrauterine device (IUD)-related abdominopelvic actinomycosis have been described recently. Surgical therapy has been the usual treatment when tubo-ovarian abscess is identified. Case: A 38-year-old woman suffering from Actinomyces pelvic abscess unresponsive to medical treatment underwent transvaginal ultrasound-guided needle aspiration. It resulted in marked improvement and avoided surgical treatment. Conclusion: Transvaginal needle aspiration of Actinomyces pelvic abscess may be an alternative to surgical therapy, thereby allowing the preservation of pelvic organs. PMID:18476111

  4. Subphrenic Abscess as a Complication of Hemodialysis Catheter-Related Infection

    Fernando Caravaca


    Full Text Available We describe an unusual case of subphrenic abscess complicating a central venous catheter infection caused by Pseudomonas aeruginosa in a 59-year-old woman undergoing hemodialysis. The diagnosis was made through computed tomography, and Pseudomonas aeruginosa was isolated from the purulent drainage of the subphrenic abscess, the catheter tip and exit site, and the blood culture samples. A transesophageal echocardiography showed a large tubular thrombus in superior vena cava, extending to the right atrium, but no evidence of endocarditis or other metastatic infectious foci. Catheter removal, percutaneous abscess drainage, anticoagulation, and antibiotics resulted in a favourable outcome.




    Full Text Available BACKGROUND AND OBJECTIVES ALA has gained importance during recent years as a result of increasing world travel, economic globalization and the growing number of chronically immunosuppressed people. AIDS and the increasing use of organ transplants have led to a new population at risk. In our study we aimed to analyse the clinical presentation and management of Amoebic liver abscess at Sree Rajarajeshwari Medical College and Hospital, Bangalore. METHODS A hospital based prospective observational study was conducted between Dec. 2013 to June 2015 in Sree Rajarajeshwari Medical College and Hospital, Bangalore. All patients admitted with suspicion of liver abscess were confirmed with ultrasonography. After establishing sonological diagnosis according to criteria, the treatment was started from the day of admission which consisted of Antibiotics, USG guided Aspiration, Pigtail catheterization and Open surgical Drainage. RESULTS Forty five cases of Amoebic liver abscess were studied; 28 patients (62% were between 21 and 40 years of age. Male-to-Female ratio was 14:1. All the patients were from rural background. History of alcoholism was present in 10 patients (22.2%. Plain X-ray abdomen showed signs of peritonitis in 2 patients. Right lobe of liver was involved in 40 cases and left lobe in 3 cases. Both lobes were involved in 2 cases. Twenty six cases were treated conservatively, 11 cases by aspiration, 6 patients by pigtail catheterization. Two patients underwent open surgical drainage for perforated liver abscess. Complications noted in our series were rupture into peritoneal cavity in 2 cases; mortality was seen in 1 case. CONCLUSION Amoebic liver abscess is still one of the commonest parasitic infections of the liver in developing countries. Prompt diagnosis, aggressive medical treatment along with minimal intervention can keep the morbidity and mortality associated with this condition to a bare minimum. The scope of surgery in this condition is

  6. Absceso hepático asociado a absceso pulmonar y endoftalmitis Liver abscess associated to lung abscess and endophthalmitis

    Jairo Cordero-Chen


    Full Text Available El absceso hepático piógeno producido por Klebsiella pneumoniae es relativamente raro y puede complicarse con lesiones sépticas a distancia. Esto se relaciona con características propias del germen que incluyen el genotipo K1, resistencia a la fagocitosis y la presencia del gen mag-A. Tales metástasis sépticas contemplan absceso pulmonar, meningitis, endocarditis bacteriana y, muy especialmente, endoftalmitis. Esta última ocurre con mayor frecuencia en pacientes diabéticos, y puede causar ceguera. Se reporta caso de absceso hepático por K. pneumoniae asociado a absceso pulmonar y endoftalmitis, y se revisa epidemiología, fisiopatología, diagnóstico y tratamiento de la entidad.The pyogenic liver abscess due to Klebsiella pneumoniae is relatively rare and can be complicated by distant septic metastases. This can be related to specific bacterial properties including genotype K1, resistance to phagocytosis and the presence of the gene mag-A. The septic metastases include lung abscess, meningitis, infective endocarditis and specially endophtalmitis. The latter is more frequent in diabetic patients and can result in blindness. We report a case of liver abscess produced by K. pneumoniae associated to pulmonary abscess and endophtalmitis, and review the epidemiology, pathophysiology, diagnosis and treatment of this disease.

  7. Role of Thr399Ile and Asp299Gly polymorphisms of toll-like receptor-4 gene in acute dental abscess

    Miri-Moghaddam, Ebrahim; Baghaee, Elnaz; Bazi, Ali; Garme, Yasaman


    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.

  8. Modern management of pyogenic hepatic abscess: a case series and review of the literature.

    Heneghan, Helen M


    BACKGROUND: Pyogenic hepatic abscesses are relatively rare, though untreated are uniformly fatal. A recent paradigm shift in the management of liver abscesses, facilitated by advances in diagnostic and interventional radiology, has decreased mortality rates. The aim of this study was to review our experience in managing pyogenic liver abscess, review the literature in this field, and propose guidelines to aid in the current management of this complex disease. METHODS: Demographic and clinical details of all patients admitted to a single institution with liver abscess over a 5 year period were reviewed. Clinical presentation, aetiology, diagnostic work-up, treatment, morbidity and mortality data were collated. RESULTS: Over a 5 year period 11 patients presented to a single institution with pyogenic hepatic abscess (55% males, mean age 60.3 years). Common clinical features at presentation were non-specific constitutional symptoms and signs. Aetiology was predominantly gallstones (45%) or diverticular disease (27%). In addition to empiric antimicrobial therapy, all patients underwent radiologically guided percutaneous drainage of the liver abscess at diagnosis and only 2 patients required surgical intervention, including one 16-year old female who underwent hemi-hepatectomy for a complex and rare Actinomycotic abscess. There were no mortalities after minimum follow-up of one year. CONCLUSIONS: Pyogenic liver abscesses are uncommon, and mortality has decreased over the last two decades. Antimicrobial therapy and radiological intervention form the mainstay of modern treatment. Surgical intervention should be considered for patients with large, complex, septated or multiple abscesses, underlying disease or in whom percutaneous drainage has failed.

  9. Spreading of multiple Listeria monocytogenes abscesses via central nervous system fiber tracts: case report.

    Bojanowski, Michel W; Seizeur, Romuald; Effendi, Khaled; Bourgouin, Patrick; Magro, Elsa; Letourneau-Guillon, Laurent


    Animal studies have shown that Listeria monocytogenes can probably access the brain through a peripheral intraneural route, and it has been suggested that a similar process may occur in humans. However, thus far, its spreading through the central nervous system (CNS) has not been completely elucidated. The authors present a case of multiple L. monocytogenes cerebral abscesses characterized by a pattern of distribution that suggested spread along white matter fiber tracts and reviewed the literature to identify other cases for analysis. They elected to include only those cases with 3 or more cerebral abscesses to make sure that the distribution was not random, but rather followed a pattern. In addition, they included those cases with abscesses in both the brainstem and the cerebral hemispheres, but excluded cases in which abscesses were located solely in the brainstem. Of 77 cases of L. monocytogenes CNS abscesses found in the literature, 17 involved multiple abscesses. Of those, 6 were excluded for lack of imaging and 3 because they involved only the brainstem. Of the 8 remaining cases from the literature, one was a case of bilateral abscesses that did not follow a fiber tract; another was also bilateral, but with lesions appearing to follow fiber tracts on one side; and in the remaining 6, to which the authors added their own case for a total of 7, all the abscesses were located exclusively in the same hemisphere and distributed along white matter fiber tracts. The findings suggest that after entering the CNS, L. monocytogenes travels within the axons, resulting in a characteristic pattern of distribution of multiple abscesses along the white matter fiber tracts in the brain. This report is the first description suggesting intraaxonal CNS spread of L. monocytogenes infection in humans following its entry into the brain. This distinct pattern is clearly seen on imaging and its recognition may be valuable in the diagnosis of listeriosis. This finding may allow for

  10. An emboligenic pulmonary abscess leading to ischemic stroke and secondary brain abscess

    Albrecht Philipp


    Full Text Available Abstract Background Ischemic stroke by septic embolism occurs primarily in the context of infective endocarditis or in patients with a right-to-left shunt and formation of a secondary cerebral abscess is a rare event. Erosion of pulmonary veins by a pulmonary abscess can lead to transcardiac septic embolism but to our knowledge no case of septic embolic ischemic stroke from a pulmonary abscess with secondary transformation into a brain abscess has been reported to date. Case presentation We report the case of a patient with a pulmonary abscess causing a septic embolic cerebral infarction which then transformed into a cerebral abscess. After antibiotic therapy and drainage of the abscess the patient could be rehabilitated and presented an impressive improvement of symptoms. Conclusion Septic embolism should be considered as cause of ischemic stroke in patients with pulmonary abscess and can be followed by formation of a secondary cerebral abscess. Early antibiotic treatment and repeated cranial CT-scans for detection of a secondary abscess should be performed.

  11. Bilateral Psoas Muscle Abscess Associated with Emphysematous Cystitis

    Jae-Ki Choi


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

  12. Liver Abscesses after Peritoneal Venous Shunt

    Hideto Kawaratani


    Full Text Available A 70-year-old man was referred to our hospital for high-grade fever with chills. He has visited our hospital for alcoholic liver cirrhosis and diabetes mellitus for over 20 years. Nine months earlier, he had received a peritoneal venous shunt (Denver shunt® because of refractory ascites. Laboratory examinations revealed elevated C-reactive protein and liver dysfunction. Ultrasonography and abdominal enhanced computed tomography showed multiple small abscesses in the right lobe of the liver. Blood culture test did not detect the pathogenic bacteria of liver abscesses. The patient was treated with antibiotics for more than 2 months and cured from the infection, but 3 months later, he developed high-grade fever again. He had a recurrence of multiple small liver abscesses involving both lobes of the liver. He was treated with antibiotics, and the abscesses disappeared within a month. After the antibiotic treatment, he had selective intestinal decontamination with kanamycin. He has had no recurrence of liver abscess for over a year. To our knowledge, this is the first report of liver abscess in a cirrhotic patient with Denver shunt. Clinicians should bear liver abscess in mind when treating patients with high-grade fever and liver dysfunction following Denver shunt implantation.

  13. Splenic abscess in typhoid fever -Surgical management

    Col Prasan Kumar Hota


    Splenic abscess is an uncommon clinical presentation in surgical practice,associated with high morbidity and mortality.Mortality may be 100 % if left untreated.Splenic abscess is also rarely encountered as a complica-tion of typhoid fever.We present here a case of multiple splenic abscesses with neuropsychiatric complications due to typhoid fever,which was managed successfully with splenectomy and other supportive therapies.Anoth-er case of single splenic abscess due to enteric fever was treated successfully with CT-guided aspiration and ap-propriate antibiotics.Being a rare entity in clinical practice,splenic abscess has been poorly studied.Haemat-ogenous seeding of the spleen due to typhoid is a common cause of splenic abscess in the tropical countries.In multiple or multiloculated abscesses aspiration usually does not succeed,which happened in our case.Sple-nectomy remains the definitive choice of treatment.However,Ultra sonography (USG)or CT-guided aspira-tion may be tried in selective cases.

  14. Emphysematous prostatic abscess with rectoprostatic fistula

    Po-Cheng Chen


    Full Text Available Emphysematous prostatic abscess is a rare but relatively serious infectious disease, and its association with rectoprostatic fistula is extremely unusual. The reported risk factors for this condition include diabetes mellitus, immunosuppression, and prostate surgery. We report a rare case of emphysematous prostatic abscess successfully treated by transurethral drainage. Nonetheless, a rectoprostatic fistula was found postoperatively. The fistula healed spontaneously without fasting or fecal diversion after suprapubic cystostomy and placement of a urethral catheter. This case highlights the importance of surgical drainage for the treatment of an emphysematous prostatic abscess and that conservative treatment can be a safe and effective approach for an associated rectoprostatic fistula.

  15. Renocolic Fistula Secondary to a Perinephric Abscess: A Late Complication of a Forgotten Double J Stent

    Kim, Jeong Hyun


    Late complications of ureteral stents are frequent, and longer indwelling times are associated with an increased frequency of complications. Although there are reports of various complications of long-term indwelling ureteral stents, a renocolic fistula secondary to a perinephric abscess resulting from an indwelling ureteral stent has not been reported. Here, we present a fatal case of a renocolic fistula secondary to a perinephric abscess caused by an encrusted forgotten double J stent in a functionally solitary kidney. PMID:19795000

    Brown, Carl J.; Hussein Jaffer; Nasir Jaffer; Claude Burul; McLeod, Robin S.


    Spinal epidural abscess is an uncommon but highly morbid illness. While it usually afflicts older, immunocompromised patients, this condition has been reported as a result of intestinal perforation in the setting of inflammatory bowel disease. Two cases of spinal epidural abscess in patients with inflammatory bowel disease are reported: one in a patient with Crohn’s disease and one in a patient with ulcerative colitis after restorative proctocolectomy.

  1. Lung abscess combined with chronic osteomyelitis of the mandible successfully treated with video-assisted thoracoscopic surgery.

    Arai, Hiromasa; Inui, Kenji; Watanabe, Keisuke; Watanuki, Kei; Okudela, Koji; Tsuboi, Masahiro; Masuda, Munetaka


    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.

  2. Adult brain abscess associated with patent foramen ovale: a case report

    Stathopoulos Georgios T


    Full Text Available Abstract Brain abscess results from local or metastatic septic spread to the brain. The primary infectious site is often undetected, more commonly so when it is distant. Unlike pediatric congenital heart disease, minor intracardiac right-to-left shunting due to patent foramen ovale has not been appreciated as a cause of brain abscess in adults. Here we present a case of brain abscess associated with a patent foramen ovale in a 53-year old man with dental-gingival sepsis treated in the intensive care unit. Based on this case and the relevant literature we suggest a link between a silent patent foramen ovale, paradoxic pathogen dissemination to the brain, and development of brain abscess.

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

    B Vijayakumar


    Full Text Available 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.

  4. Epidemiology and mortality of liver abscess in end-stage renal disease dialysis patients: Taiwan national cohort study.

    Chon-Seng Hong

    Full Text Available BACKGROUND AND OBJECTIVES: To determine the incidence rates and mortality of liver abscess in ESRD patients on dialysis. DESIGN SETTING PARTICIPANTS & MEASUREMENTS: Using Taiwan's National Health Insurance Research Database, we collected data from all ESRD patients who initiated dialysis between 2000 and 2006. Patients were followed until death, end of dialysis, or December 31, 2008. Predictors of liver abscess and mortality were identified using Cox models. RESULTS: Of the 53,249 incident dialysis patients identified, 447 were diagnosed as having liver abscesses during the follow-up period (224/100,000 person-years. The cumulative incidence rate of liver abscess was 0.3%, 1.1%, and 1.5% at 1 year, 5 years, and 7 years, respectively. Elderly patients and patients on peritoneal dialysis had higher incidence rates. The baseline comorbidities of diabetes mellitus, polycystic kidney disease, malignancy, chronic liver disease, biliary tract disease, or alcoholism predicted development of liver abscess. Overall in-hospital mortality was 10.1%. CONCLUSIONS: The incidence of liver abscess is high among ESRD dialysis patients. In addition to the well known risk factors of liver abscess, two other important risk factors, peritoneal dialysis and polycystic kidney disease, were found to predict liver abscess in ESRD dialysis patients.

  7. [Latex agglutination test in amebic liver abscess].

    Gómez Maganda y Silva, T; García Carrizosa, R; Torres Valadez, F; Ortiz Ramírez, E; Villaseñor de la Parra, C; Flores González, A; Gómez García, E


    Amebic hepatic abscesses are one of the most frequent and serious complications of intestinal amibiasis. Although many methods exists with which the diagnosis can be made, frequently problems do arise. Serologic reactions play an important role in the diagnosis of amebic hepatic abscess. Among the most useful of the serological tests, is that which evaluates agglutination with latex particles. Latex agglutination was positive in 98.5% of 200 cases of proved amebic hepatic abscess. The pros and cons of the utility of this test compared with other serological tests are discussed. It is concluded that or the especialist as well as the general practicioner latex agglutination can be extremely useful in the diagnosis of amebic hepatic abscess.

  8. Successful medical treatment of spinal epidural abscess.

    Xiao, Bo-Ren; Wang, Chih-Wei; Lin, Jung-Chung; Chang, Feng-Yee


    Spinal epidural abscess is a rare but potentially fatal disease. A 67-year-old female suffered fever and painful swelling of the right knee and lower leg for one week. Both synovial fluid and blood cultures yielded methicillin-sensitive Staphylococcus aureus. Low back pain developed and fever was sustained despite the administration of intravenous oxacillin. Magnetic resonance imaging (MRI) of the thoracolumbar spine revealed spinal epidural abscess from T12 to S1. Because of severe hypoalbuminemia and general anasarca and followed by exploratory laparotomy for massive duodenal bleeding, she did not receive surgical intervention for the spinal epidural abscess. After intravenous administration of oxacillin 2 g 4-hourly for 12 weeks, she recovered and follow-up MRI confirmed the efficacy of the medical treatment. She remained well at 1-year follow-up. In a patient with minimal neurological deficit or surgical contraindication, spinal epidural abscess can be successfully treated with a medical regimen.

  9. Pyogenic Liver Abscess. A Case Report

    Miguel Ángel Serra Valdés


    Full Text Available Liver abscesses account for 13% of all abdominal abscesses and 48% of those occurring in the viscera. The bacterial or pyogenic liver abscesses are the most frequent. A case of a 34-year-old woman of mixed race with history of gallstones (2011, extrahepatic obstructive jaundice caused by cholelithiasis (May 2012, cholangitis after endoscopic retrograde cholangiopancreatography (ERCP and cholecystectomy (August 2012 due to gallstones is presented. In September 2012, she began suffering from high fever with chills every day, usually in the evenings. In addition, she presented night sweats, loss of appetite, weight loss, nausea and pain in the right upper quadrant of the abdomen which was sharp, permanent and annoying sometimes. The signs and symptoms, history, ultrasound scan and multislice computed tomography confirmed the diagnosis of pyogenic liver abscess. The risk factors leading to the infection were well-identified. The patient progressed satisfactorily with the medical treatment provided.

  11. Renal hemorrhagic actinomycotic abscess in pregnancy.

    Smid, Marcela C; Bhardwaj, Neha R; Di Giovanni, Laura M; Eggener, Scott; Torre, Micaela Della


    Actinomyces israelii is a gram-positive, filamentous anaerobic bacteria colonizing the oral and gastrointestinal tracts. Retroperitoneal actinomycotic abscess is uncommon and its rare presentation as a hemorrhagic mass may be confused with malignancy. We present a case of this unusual infection complicating pregnancy. Increased awareness of actinomycotic abscess in the differential diagnosis of renal mass concerning for malignancy is critical to early recognition and treatment of this rare infection and most importantly, avoidance of unnecessary surgical intervention.

  14. Deep neck abscesses: the Singapore experience.

    Lee, Yan Qing; Kanagalingam, Jeevendra


    This study aims to review our experience with deep neck abscesses, identify key trends, and improve the management of this condition. This is a retrospective chart review of patients diagnosed with deep neck abscesses in the Department of ENT (Otorhinolaryngology) at Tan Tock Seng Hospital, Singapore between 2004 and 2009. Patient demographics, etiology, bacteriology, systemic disease, radiology, treatment, complications, duration of hospitalization, and outcomes were reviewed. 131 patients were included (64.9% male, 35.1% female) with a median age of 51.0 years. 54 (41.2%) patients had diabetes mellitus. The parapharyngeal space (23.7%) was the most commonly involved space. Odontogenic and upper airway infections were the leading causes of deep neck abscesses (28.0% each). Klebsiella pneumoniae (27.1%) was the most commonly cultured organism in this study and among the diabetic patients (50.0%). 108 (82.4%) patients underwent surgical drainage. 42 patients suffered complications. All 19 patients, who had upper airway obstruction, had either a tracheostomy or intubation. Patients with multi-space abscesses, diabetes mellitus, and complications had prolonged hospitalizations. Old age and diabetes are risk factors for developing deep neck abscesses and their sequelae. The empiric choice of antibiotics should recognize that a dental source is likely, and that Klebsiella is most common in diabetics. Surgical drainage and adequate antibiotic coverage remains the cornerstone of treatment of deep neck abscesses. Therapeutic needle aspiration may successfully replace surgical drainage, if the abscesses are small and no complications are imminent. Airway obstruction should be anticipated in multi-space and floor of mouth abscesses.

  15. Scalp abscess--a cautionary tale.

    Nugent, Nora F


    Transcranial extension of frontal sinus infection is a rare, but not eradicated entity. We present a 21-year-old male, in whom a persistent scalp abscess heralded the discovery of skull vault osteomyelitis and extradural abscesses secondary to frontal sinusitis. Patients with prolonged or unusual symptoms with a history of sinusitis or trauma warrant further investigation as they may have developed serious intracranial complications. Urgent management, both surgical and antimicrobial, is indicated in such scenarios.

  16. Intraventricular tuberculous abscess : a case report.

    Vajramani G


    Full Text Available Ventricles can be involved in different ways in neurotuberculosis, however, the occurrence of intraventricular abscess has been rarely reported. We report a young woman who had intraventricular tubercular abscess. Cranial computed tomographic scan showed hypodense ring enhancing lesion in the right lateral ventricle with unilateral hydrocephalus. She underwent parasagittal craniotomy with total excision of the lesion. The pus obtained from the lesion was teeming with acid fast bacilli.

  18. Bilateral Brodie's abscess at the proximal tibia.

    Buldu, Halil; Bilen, Fikri Erkal; Eralp, Levent; Kocaoglu, Mehmet


    Brodie's abscess is a form of subacute osteomyelitis, which typically involves the metaphyses of the long tubular bones, particularly in the tibia. The diagnosis is usually made incidentally, as there are no accompanying symptoms or laboratory studies. Bilateral involvement at the proximal tibia is unusual. However, orthopaedic surgeons should be aware of this entity, as it may present without symptoms. Checking the contralateral limb for concomitant Brodie's abscess is recommended.

  19. [Drainage of amoebic liver abscess by single incision laparoscopic surgery. Report of a case].

    Telich-Tarriba, José Eduardo; Parrao-Alcántara, Iris Jocelyn; Montes-Hernández, Jesús Manuel; Vega-Pérez, Jesús


    Single incision laparoscopic surgery has increased recently due to successful results, achieved in several procedures. The aim of the present work is to present the first case in which single incision laparoscopy is used for the drainage of an amoebic liver abscess. A 44-year-old man presented with intense right upper quadrant pain, generalised jaundice, tachycardia, fever, hepatomegaly and a positive Murphy's sign. Laboratory results revealed an increased plasma bilirubin, elevated alkaline phosphatase and transaminases, leucocytosis, negative viral panel for hepatitis, and positive antibodies against Entamoeba histolytica. On an abdominal computed tomography a 15 × 12.1 cm hypodense lesion was observed in the patient's liver, identified as an amoebic liver abscess. Analgesics and antibiotics were started and subsequently the patient was submitted to laparoscopic drainage of the abscess using a single port approach. Drainage and irrigation of the abscess was performed. Four days later the patient was discharged without complications. Management of amoebic liver abscess is focused on the elimination of the infectious agent and obliteration of the abscess cavity in order to prevent its complications, especially rupture. Laparoscopic surgery has proved to be a safe and effective way to manage this entity. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

  20. [Does the site of compression of spinal roots affect the therapeutic results in discogenic cauda equina syndrome?].

    Sulla, I


    Experimental investigations and differences in the anatomical structure of roots of the cauda equina indicate that the most serious sequelae should be produced in the short portion beyond the spine. The objective of the present work was to verify this assumption. The authors examined 70 subjects (24 women and 46 men) operated on account of discogenic syndrome of the cauda equina in 1982 -1992; statistical analysis of the results by means of the X2-test revealed that the condition had in the majority of patients permanent sequelae. Except for restored sensitivity it was not possible to prove a relationship between the site of the compression and the therapeutic results. Key words: cauda equina syndrome, site of compression.

  1. Heavy Ion Physics at the CERN SPS: Roots 1974-1984 and Key Results

    CERN. Geneva


    Two communities, Nuclear and Particle Physics, had to come together to open up a new field at the CERN SPS in the early eighties, bringing CERN to the forefront worldwide until the start of RHIC in 2000. I will discuss the period before that, including the basic new ideas on parton deconfinement, key workshops, alternative accelerator options in the LBL-GSI-CERN triangle, and the final convergence of the three labs on the SPS, sacrificing any home future in this field for the first two. In 1984, 5 major experiments were approved for initially O16 and S32 beams at the SPS, with an unprecedented reuse of existing experimental equipment. Subsequent evolution followed thanks to intense learning processes, leading to a second generation of much improved or completely new experiments together with Pb beams starting in 1994. I will summarise the key results and their (then still cautious) interpretation as of 2000. They were used as an input to a Press Conference at CERN, announcing the detection of a 'n...

  2. Laparoscopy may have a role in the drainage of liver abscess: Early experience at Owerri, Nigeria

    Christopher N Ekwunife


    Full Text Available Background: Image-guided percutaneous drainage with antimicrobial agents is the standard modality of treatment of liver abscess. Open surgical drainage, and lately laparoscopic drainage becomes useful in selected patients. Nigeria is awakening late to the laparoscopic surgery revolution. Public health institutions have started making enormous investments in minimal access surgery, which can augment deficient diagnostic capacities. Objective: To describe the outcomes of the patients who underwent laparoscopic liver abscess drainage at the Federal Medical Centre, Owerri. Materials and Methods: A retrospective analysis of the laparoscopic liver abscess drainage procedures done between the period September 2007 and December 2012 was done. Results: A total of eight patients in the study period were worked up for abscess surgical drainage based on ultrasound (seven cases and computed tomography (one case supported localized collection in the liver. Intraoperatively, one patient was noticed to have nodules on the liver that was later confirmed as hepatocellular carcinoma. Operating time ranged from 37 to 126 min. There was no conversion to open surgery. On the follow-up, one patient had residual abscess of 45 mm diameter size, after 6 weeks, and in whose aspirate acid-fast bacilli were identified. Conclusion: Laparoscopic drainage should be considered in the management of liver abscess.

  4. Ilio-psoas abscess in the paediatric population: treatment by US-guided percutaneous drainage

    Kang, M.; Gupta, S.; Gulati, M.; Suri, S. [Department of Radiodiagnosis and Imaging, Postgraduate Institute of Medical Education and Research, Chandigarh 160012 (India)


    Background. Image-guided percutaneous drainage has been shown to be a safe and effective alternative to surgery in the management of psoas abscess in adults and adolescents. There is little information on its use in children. Objective. To evaluate the safety and efficacy of US-guided percutaneous needle aspiration and catheter drainage of ilio-psoas abscesses. Materials and methods. A retrospective review of 14 children with 16 ilio-psoas abscesses (10 pyogenic and 4 tuberculous) who were treated by US-guided percutaneous needle aspiration (n = 5) or catheter drainage (n = 9) along with appropriate antimicrobial therapy. Results. Percutaneous treatment was successful in 10 of the 14 patients; all showed clinical improvement within 24-48 h of drainage and subsequent imaging demonstrated resolution of the abscess cavities. Surgery was avoided in all of these ten patients except one, who underwent open surgical drainage of ipsilateral hip joint pus. Of the other four patients, two had to undergo surgical drainage of the ilio-psoas abscesses after failure of percutaneous treatment, one improved with antibiotics after needle aspiration failed to yield any pus, and one died of continuing staphylococcal septicaemia within 24 h of the procedure. There were no procedural complications. Conclusions. Percutaneous drainage represents an effective alternative to surgical drainage as a supplement to medical therapy in the management of children with ilio-psoas abscesses. (orig.)

  5. Abscess of the cervical spine secondary to injection site infection in a heifer.

    Braun, Ueli; Gerspach, Christian; Kühn, Karolin; Bünter, Julia; Hilbe, Monika


    Abscesses in the neck region can result from infection associated with injection of drugs into the neck muscles. To our knowledge, there have been no reports of osteomyelitis of the cervical vertebra and spinal cord compression secondary to an abscess in the neck. This case report describes the findings in a 9.5-month-old heifer with an abscess of the cervical spine secondary to injection site infection. The main clinical findings were swelling on the left side of the neck, proprioceptive deficits in all limbs and generalised ataxia. The ultrasonographic examination of the swelling showed an abscess. Radiographs showed a well-defined lytic lesion in 5th cervical vertebra (C5). Postmortem examination revealed an intramuscular encapsulated abscess on the left side of the neck at the level of C5. The abscess had invaded the vertebral canal and caused marked compression of the spinal cord. Injection technique is critical for the prevention of problems such as those described in this report. Sterile hypodermic needles must be used, and the volume of drug per injection site limited to 10-15 ml in young cattle.

  6. [Cases of pyogenic iliopsoas abscesses in military men].

    Solov'ev, A A; Petrushin, V V; Gaĭduk, V P; Zotov, I V; Pchelkin, V A; Siniakov, V F


    Four cases of pyogenic inflammation of the iliolumbar muscle were analyzed and 3 clinical cases of this disease in military men are described. A rare case of abscess of the iliolumbar muscle complicated by secondary appendicitis is also described. A hematogenic way of infection against the background of microtraumas and hematomas with m. Iliopsoas was the main one in the patients observed that was due to specificities of military service: permanent physical activity, pustular diseases of the lower extremities. The main clinical symptom of the disease is the symptom of the iliolumbar muscle. Ultrasonic scanning is the most informative method of diagnosis among additional methods. Operative treatment of the piogenic iliopsoas abscess is the only method of treatment, the open operative interventions by the retroperitoneal access being preferred. Antibacterial therapy in the postoperative period is based on the results of inoculation of the purulent discharge from the wound. Broad spectrum antibiotics must be used due to possible anaerobic character of the purulent inflammation.

  7. Tubo-ovarian abscess with Morganella morganii bacteremia.

    Chou, Yen Yi; Chiu, Sheng Kang; Lai, Hung Cheng; Chang, Feng Yee


    Tubo-ovarian abscess caused by Morganella morganii is unusual. A 54-year-old menopausal woman visited the emergency room with lower abdominal pain, vomiting, and fever for 4 days. Pelvic examination revealed lifting tenderness over the right adnexum without motion tenderness of the uterus. Pelvic sonogram revealed a cystic lesion with heterogeneous content in the right ovary. Salpingo-oophoritis was suspected. Clindamycin and gentamicin were administered intravenously after obtaining blood cultures. Laparoscopy was done because of sustained fever, and an ovarian abscess was found. Laparoscopic salpingo-oophorectomy was performed. The patient was discharged 5 days later and oral clindamycin was prescribed. However, she was readmitted due to intermittent fever. The result of blood culture obtained before surgery disclosed M. morganii, which was resistant to clindamycin and cefazolin. Her symptoms resolved after administration of intravenous flomoxef. This report highlights the fact that antimicrobial resistance of M. morganii may complicate the management and outcome of this infection.

  8. [Evolution of Root Nodule Bacteria: Reconstruction of the Speciation Processes Resulting from Genomic Rearrangements in a Symbiotic System].

    Provorov, N A; Andronov, E E


    The processes of speciation and macroevolution of root nodule bacteria (rhizobia), based on deep rearrangements of their genomes and occurring in the N₂-fixing symbiotic system, are reconstructed. At the first stage of rhizobial evolution, transformation of free-living diazotrophs (related to Rhodopseudomonas) to symbiotic N₂-fixers (Bradyrhizobium) occurred due to the acquisition of the fix gene system, which is responsible for providing nitrogenase with electrons and reducing equivalents, as well as for oxygen-dependent regulation of nitrogenase synthesis in planta, and then of the nod genes responsible for the synthesis of the lipo- chito-oligosaccharide Nod factors, which induce root nodule development. The subsequent rearrangements of bacterial genomes included: (1) increased volume of hereditary information supported by species, genera (pan-genome), and individual strains; (2) transition from the unitary genome to a multicomponent one; and (3) enhanced levels of bacterial genetic plasticity and horizontal gene transfer, resulting in formation of new genera, of which Mesorhizobium, Rhizobium, and Sinorhizobium are the largest, and of over 100 species. Rhizobial evolution caused by development and diversification of the Nod factor synthesizing systems may result in both increased host specificity range (transition of Bradyrhizobium from autotrophic to symbiotrophic carbon metabolism in interaction with a broad spectrum of legumes) and to its contraction (transition of Rhizobium and Sinorhizobium to "altruistic" interaction with legumes of the galegoid clade). Reconstruction of the evolutionary pathway from symbiotic N₂-fixers to their free-living ancestors makes it possible to initiate the studies based on up-to-date genome screening technologies and aimed at the issues of genetic integration of organisms into supracpecies complexes, ratios of the macro- and microevolutionary mechanisms, and developmetn of cooperative adaptations based on altruistic

  9. Restored river corridors: first results on the effects of flow variability on vegetation cuttings survival rate and related root architecture

    Pasquale, N.; Perona, P.; Jiang, Z.; Burlando, P.


    Understanding and predicting the evolution of river alluvial bed forms toward a vegetated or a non-vegetated morphology have important implications for restored river corridors and the related ecosystem functioning (see also Schäppi et al, this session). Vegetation recruitment and growth on non-cohesive material of river corridors, such as gravel bars and islands of braided river, depend on the ability of roots to develop and anchor efficiently such to resist against flow erosion. In this work, we study the interannual morphological evolution of a gravel bar island, the survival rate and the growth of a number of plots with different density and orientation of transplanted cuttings (Salix Alba), the space and time dynamics of which depend on erosion and deposition processes due to floods. Our purpose is to identify island locations where the hydrodynamic conditions are more suitable for plants germination, growth and survival in relation to the river hydrograph statistics. This information is a first step to build a stochastic model able to predict the future evolution and progress of the restoration action of the investigated river reach. We focus at the main island of River Thur at Niederneunforn (Canton Thurgau, Switzerland), the restoration success of which is investigated from a mechanistic viewpoint in the research project "REstored CORridor Dynamics" ( Accordingly, we analyze two recent Digital Elevation Models (1 year difference), which were first corrected to account for the river bathymetry, and then we compare them in order to extract relevant interannual morphological changes. Using a two dimensional numerical hydrodynamic model we simulate several flow conditions ranging from the minimum recorded flow up to the one that completely inundates the island. Hence, we build inundation maps of the island that we associate to the frequency and the submergence duration of every area. We then correlate such results to the observed survival

  10. Brain Abscess after Percutaneous Therapy for Trigeminal Neuralgia

    Michele Acqui


    Full Text Available We report a case of brain abscess following the percutaneous treatment for trigeminal neuralgia. This procedure envisages the access with a needle into the middle cranial fossa through the oral cavity. Thus, in this case, the bacterial infection can be more likely ascribed to the possible contamination of the needle inside the oral cavity rather than to other frequent and more controllable causes of infection like an imperfect sterilization of surgical instruments or an inadequate antiseptic preparation of both operator’s hands and patient’s skin. The subsequent brain abscess was treated with antibiotic therapy (Vancomycin 2 gr a day and Meropenem 8 g a day for 22 days before the surgical procedure and 30 days after, until complete normalization of laboratory parameters, clinical parameters, and neurological symptoms and surgical drainage, although the culture of the abscess capsule and the purulent material resulted sterile. In conclusion, the percutaneous therapy for trigeminal neuralgia can be objectively related to risks, even if performed by expert hands. Therefore, it is important that the patient should be advised regarding risks/benefits and/or septic complications of such procedures, even if they occur very seldom. An association of surgery and antibiotic therapy results as effective treatment for this pathologic condition.

  11. Endoscopic Drainage of an Odontogenic Pterygoid Muscle Abscess

    Rickul Varshney


    Full Text Available The infratemporal fossa (ITF is a potential space bounded by bony structures that can be occupied by both benign and malignant tumors. It is also a potential area of abscess development, most commonly of dental origin. As with any abscess, the treatment of an ITF abscess is surgical drainage. We present a case of an ITF abscess involving the pterygoid muscles following dental extraction in a poorly controlled diabetic patient. The ITF was accessed with an endoscopic transseptal approach through the maxillary sinus to drain the abscess. This case of successful management supports the feasibility of the endoscopic approach in dealing with abscesses of the ITF.

  15. Pyogenic liver abscess: An audit of 10 years’ experience

    Tony CY Pang; Thomas Fung; Jaswinder Samra; Thomas J Hugh; Ross C Smith


    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.

  16. Bacillus cereus brain abscesses occurring in a severely neutropenic patient: successful treatment with antimicrobial agents, granulocyte colony-stimulating factor and surgical drainage.

    Sakai, C; Iuchi, T; Ishii, A; Kumagai, K; Takagi, T


    Multiple brain and liver abscesses developed immediately after Bacillus cereus bacteremia in a neutropenic patient with acute lymphoblastic leukemia. After even 8 weeks of antimicrobial chemotherapy together with administration of granulocyte colony-stimulating factor, every infectious process disappeared but the patient's headache has still persisted. Because the wall of one brain abscess became thin and was in danger of rupturing into the ventricle, surgical drainage was performed, resulting in disappearance of headache and resolution of brain abscess. The present case indicates that a combined medical and surgical approach is mandatory to treat patients with brain abscesses.

  17. Abscess or tumour? Lumbar spinal abscess mimicking a filum terminale tumour.

    Sajjad, Jahangir; Kaliaperumal, Chandrasekaran; O'Sullivan, Michael


    A 62-year-old woman presented with a 4-month history of central lower backache and a 2-week history of progressive bilateral leg weakness. She also complained of numbness on her left thigh and gluteal region, associated with urinary hesitancy and constipation. On examination, she had bilateral partial foot drop, absent knee and ankle reflexes and a negative Babinski's reflex and associated hyperaesthesia in L3 distribution bilaterally with decreased anal tone. Laboratory results revealed normal inflammatory markers. MRI scan demonstrated a large uniformly enhancing lesion in the filum terminale suggestive of a lumbar spinal tumour. An emergency spinal laminectomy from L3 to S2 was performed. Per operatively, the duramater was thickened and hyperaemic. The histopathology report suggested inflammation with no evidence of malignancy. Tissue specimen of cultured Staphylococcus aureus was sensitive to flucloxacillin. A final diagnosis of lumbar spinal abscess was made and subsequent antibiotic treatment led to good clinical recovery.

  1. Clinical presentation and diagnostic difficulties in amoebic liver abscess

    Kaushal D Suthar


    Full Text Available Background Amoebic liver abscess (ALA is a common and major health problem in India. ALA has a highly variable presentation, causing diagnostic difficulties. Early and correct diagnosis of Amoebic liver abscess is essential, because delayed diagnosis and treatment leads to complications which has significantly higher morbidity and mortality than uncomplicated disease. Objective To find out different clinical presentation and its differential diagnosis in order to establish early diagnosis of ALA. Patients and Methods This retrospective, observational study was carried out in the Department of Surgery during February 2010 to May 2013. Inclusion criteria were defined. The data of patients were enrolled according to variables in performa predesigned for this study and analyzed. Results 187 cases of ALA were enrolled with male to female ratio of 2.8:1. Right hypochondrial pain occurred in 69.52%, left hypochondrial pain occurred in 6.41%, pain radiating to tip of right shoulder in 8.02%, fever in 86.64%, co-incident diarrhea in 36.37% and concurrent pulmonary symptoms in 12.84%. The most common signs were tender hepatomegaly in 73.74% and jaundice in 17.65%. 3.20% patients had past history of aspiration of ALA. 23.52% patients had ruptured abscess. 11.12% were due to delayed diagnosis and 1.60% was ruptured despite treatment. Mortality rate was 3.20% amongst patients with ruptured ALA. Diabetes, hypertension, AIDS and alcoholism were commonly associated co morbidities. Right lobe (82.36% is commonly involved than left lobe and single abscess (83.42% was more common than multiple abscess. Diagnosis was missed in 30.48% patients particularly those with atypical presentations. Ultrasonography, Computerized tomography (CT scan with diagnostic aspiration were useful in diagnosing ALA. Conclusion The typical features of ALA, which include pain, fever and tender hepatomegaly, are nonspecific. ALA may be missed because of variable clinical features and

  2. Contrast-enhanced ultrasound in the differentiation between phlegmon and abscess in Crohn's disease and other abdominal conditions

    Ripollés, Tomás, E-mail:; Martínez-Pérez, María J., E-mail:; Paredes, José M., E-mail:; Vizuete, José, E-mail:; García-Martínez, Esteban, E-mail:; Jiménez-Restrepo, David H., E-mail:


    Aim: To evaluate the diagnostic accuracy of the contrast-enhanced ultrasound (CEUS) to differentiate between intra-abdominal phlegmon and abscess. Methods: We retrospectively reviewed all contrast-enhanced ultrasound performed between June 2006 and May 2012 to identify patients with the terms “inflammatory mass”, “phlegmon” or “abscess” on the sonographic report. The initial CEUS report was used for the diagnosis of phlegmon or abscess. Results: 71 inflammatory masses in 50 patients were identified in CEUS examination. 57 masses, 21 phlegmons and 36 abscesses, were confirmed by other imaging techniques, percutaneous drainage or surgery. CEUS specificity for the diagnosis of abscess was 100%. Kappa coefficient between CEUS and other techniques in the diagnosis of phlegmon or abscess was excellent (kappa = 0.972). Only in one patient surgery detected a small abscess (<2 cm) within a phlegmon that not was detected by CEUS. Statistically significant differences were found between the size of the abscesses before and after contrast agent injection. The interobserver agreement in the diagnosis of phlegmon or abscess was excellent (kappa = 0.953). Conclusions: CEUS is an accurate method for differentiating between intra-abdominal phlegmon and abscess in gastrointestinal conditions, especially in CD. Its use may help to better define the size of the collections and avoid other techniques that use ionizing radiation. CEUS should be used to confirm an inflammatory mass identified at US.

  3. Predicting Neck Abscess with Contrast-Enhanced Computed Tomography


    Neck abscesses are difficult to diagnose and treat. Currently, contrast-enhanced computed tomography (CECT) is the imaging modality of choice. The study aims to determine the predictive value of CECT findings in diagnosing neck abscess, causes of neck abscess and the most common neck space involved in the local population. 84 consecutive patients clinically suspected to have neck abscess who underwent CECT and surgical confirmation of pus were included. Demographic and clinical data were reco...

    Splenic abscess is a rare entity normally associated with underlying diseases. We report a case of splenic abscess with large gas formation in a non-diabetic and non-immunosuppressed patient after surgery for colon perforation. The most frequent cause of splenic abscess is septic embolism arising from bacterial endocarditis. Splenic abscess has a high rate of mortality when it is diagnosed late. Computed tomography resolved any diagnostic doubt, and subsequent surgery confirmed the diagnosis.



    ABSTRACT: Various aerobic and anaerobic bacteria have been r eported as causative agents of brain abscess but only a few cases of enterococcal brain abscesses have been reported. We report a case of enterococcal brain abscess of otoge nic origin in a 35 year old male who was known case of chronic suppurative otitis media (CSOM) and cholesteotoma of the right ear. The abscess material culture yielded an isolate which w as identified as Enterococcus faecium ...

  6. Outcome of percutaneous continuous drainage of psoas abscess: A clinically guided technique

    Bharat R Dave


    Full Text Available Background: Percutaneous aspiration of abscesses under ultrasonography (USG and computer tomography (CT scan has been well described. With recurrence rate reported as high as 66%. The open drainage and percutaneous continuous drainage (PCD has reduced the recurrence rate. The disadvantage of PCD under CT is radiation hazard and problems of asepsis. Hence a technique of clinically guided percutaneous continuous drainage of the psoas abscess without real-time imaging overcomes these problems. We describe clinically guided PCD of psoas abscess and its outcome. Materials and Methods: Twenty-nine patients with dorsolumbar spondylodiscitis without gross neural deficit with psoas abscess of size >5 cm were selected for PCD. It was done as a day care procedure under local anesthesia. Sequentially, aspiration followed by guide pin-guided trocar and catheter insertion was done without image guidance. Culture sensitivity was done and chemotherapy initiated and catheter kept till the drainage was <10 ml for 48 hours. Outcome assessment was done with relief of pain, successful abscess drainage and ODI (Oswestry Disability Index score at 2 years. Results: PCD was successful in all cases. Back and radicular pain improved in all cases. Average procedure time was 24.30 minutes, drain output was 234.40 ml, and the drainage duration was 7.90 days. One patient required surgical stabilisation due to progression of the spondylodiscitis resulting in instability inspite of successful drainage of abscess. Problems with the procedure were noticed in six patients. Multiple attempts ( n = 2, persistent discharge ( n = 1 for 2 weeks, blocked catheter ( n = 2 and catheter pull out ( n = 1 occurred with no effect on the outcome. The average ODI score improved from 62.47 to 5.51 at 2 years. Conclusions: Clinically guided PCD is an efficient, safe and easy procedure in drainage of psoas abscess.

  7. Endoscopic ultrasound-guided drainage of pelvic abscess: A case series of 8 patients

    Muhammed; Hadithi; Marco; J; Bruno


    AIM: To show the safety and effectiveness of endo-scopic ultrasound(EUS)-guided drainage of pelvic ab-scess that were inaccessible for percutaneous drainage. METHODS: Eight consecutive patients with pelvic abscess that were not amenable to drainage under computed tomography(CT) guidance were referred for EUS-guided drainage. The underlying cause of the abscesses included diverticulitis in 4, postsurgical surgi-cal complications in 2, iatrogenic after enema in 1, and Crohn’s disease in 1 patient. Abscesses were all drained under EUS guidance via a transrectal or transsigmoidal approach. RESULTS: EUS-guided placement of one or two 7 Fr pigtail stents was technically successful and uneventful in all 8 patients(100%). The abscess was perisigmoidal in 2 and was multilocular in 4 patients. All procedures were performed under conscious sedation and without fluoroscopic monitoring. Fluid samples were success-fully retrieved for microbiological studies in all cases and antibiotic policy was adjusted according to cultureresults in 5 patients. Follow-up CT showed complete re-covery and disappearance of abscess. The stents were retrieved by sigmoidoscopy in only two patients and had spontaneously migrated to outside in six patients. All drainage procedures resulted in a favourable clinical outcome. All patients became afebrile within 24 h after drainage and the mean duration of the postprocedure hospital stay was 8 d(range 4-14). Within a median follow up period of 38 mo(range 12-52) no recurrence was reported. CONCLUSION: We conclude that EUS-guided drain-age of pelvic abscesses without fluoroscopic monitoring is a minimally invasive, safe and effective approach that should be considered in selected patients.

  8. Pituitary abscess during pregnancy: Management dilemmas

    Krishna Chaitanya Joshi


    Full Text Available Pituitary abscess is a rare disorder and only one case of pituitary abscess in pregnancy has been reported in the literature. Since, its presenting manifestations are non-specific; the diagnosis is usually made per-operatively. A 35-year-old pregnant lady, with a sellar mass was managed successfully with trans-sphenoidal drainage of the abscess and antibiotic therapy. We discuss the unique set of problems faced in diagnosis and management. Choice of antibiotics, management of intra-operative cerebrospinal fluid leak and absence of any growth on cultures made the overall management challenging. Although, it can present with a dramatic course suggestive of central nervous system infection or a pituitary mass, but more often it mimics an indolent lesion, which can pose as a diagnostic and therapeutic challenge.

  9. Renal abscess caused by Salmonella Typhi

    Amarjeet Kaur


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




    Full Text Available This is a report of a very rare case of recurrent subclitoral abscess. Its etiology and the best treatment of the disease is here in discussed. We, the same as Sur, believe that marsupialization is the most promising treatment. Recurrent periclitoral abscess has been described previously5. s ome of the authors believe that it is part of the pilonidal disease. The first pilonidal cyst in 7 the clitoral region was introduced by Palmer (1957."nAnother case of pilonidal sinus of clitoris was repor-2 ted by Betson . All of the researchers are not in this opinion that the disease is necessarily a pilonidal sinus 1 3,and, sometimes, there is not any hair in the epithelium lining of the cyst. One case of recurrent subclitoral abscess treated by marsupialization is presented here.

  11. Filarial abscess in the submandibular region

    Rupinder Kaur


    Full Text Available Filariasis is a parasitic infectious disease caused by filarial nematode worms. These worms mainly dwell in subcutaneous tissues and lymphatics of the human host, with a predilection for lower limbs, retroperitoneal tissues, spermatic cord, and epididymis. Oral or perioral involvement of the filarial nematode is rare. This case report describes a filarial abscess in the right submandibular region. Fine needle aspiration cytology of the abscess revealed the presence of microfilaria of Wuchereria bancrofti species. The parasite was also present in the peripheral blood smear. Filarial infection presenting in this region is unusual and can cause diagnostic dilemma. The clinician can consider filariasis as one of the differential diagnosis while treating those abscesses in the orofacial region that are unresponsive to routine management, especially, patients hailing from endemic areas.

  12. Brodie's abscess. A long-term review.

    Stephens, M M; MacAuley, P


    In 20 patients with 21 Brodie's abscesses, a long-term review revealed that 13 occurred in the second decade of life. All had local symptoms for six weeks or more. The tibia was involved in 11 cases and seven of these were in the proximal metaphysis. The erythrocyte sedimentation rate (ESR) was elevated in only six cases. When the ESR was more than 40 mm per hour, recurrence was more likely. Staphylococcus aureus was cultured from 11 abscesses. Curettage and antibiotics for six weeks were adequate for treatment in most cases. However, lesions larger than 3 cm in diameter should be grafted, and patients with an elevated ESR require more aggressive decompression and prolonged antibiotic therapy. Lesions within the neck of the femur pose particular anatomic problems and should not be approached laterally. All cases were followed to full bone maturity. No significant leg length inequality was clinically or roentgenologically apparent. If an abscess was juxtaphyseal, deformity of the epiphysis could develop.

  13. Amoebic liver abscess production by Entamoeba dispar.

    Dolabella, Silvio S; Serrano-Luna, Jesús; Navarro-García, Fernando; Cerritos, René; Ximénez, Cecilia; Galván-Moroyoqui, José Manuel; Silva, Edward F; Tsutsumi, Víctor; Shibayama, Mineko


    Although Entamoeba dispar displays a similar morphology to Entamoeba histolytica, cellular and molecular studies have revealed significant differences between these two amoebae, including the former being characterized as non-pathogenic and the later as pathogenic. However, recent in vivo and in vitro experiments have shown that E. dispar strains of different origin are capable of causing liver damage and destroying cell culture lines in the presence of common intestinal bacteria. These results suggested that E. dispar may present pathogenic behavior according to the specific E. dispar strain, culture and environmental conditions. To investigate this possibility, we carried out in vivo and in vitro studies using a xenic strain E. dispar (ICB-ADO) isolated from a symptomatic non-dysenteric Brazilian patient. This strain was able to induce liver necrosis in a hamster model that was more severe than that produced by E. histolytica. The ICB-ADO isolate also caused significantly more destruction of cultured MDCK cells and increased loss of transepithelial resistance than did the E. histolytica. Xenic E. dispar exhibited high proteolytic activity, which was partially inhibited by the addition of cysteine-protease inhibitors. Based on our biochemical and molecular characterization of E. dispar (ICB-ADO) xenic culture and its ability to produce liver abscesses, we conclude that this specific strain can indeed produce tissue damage, distinct from the frequently used non- pathogenic E. dispar SAW 760 strain.

  14. Microbial flora of odontogenic abscesses in pet guinea pigs.

    Minarikova, A; Hauptman, K; Knotek, Z; Jekl, V


    Abscesses of odontogenic origin in guinea pigs pose a serious health problem and need to be treated with a combination of surgical and medical therapy. The aim of this prospective study was to describe the microbial flora of odontogenic abscesses associated with osteomyelitis in 24 pet guinea pigs, to perform antibiotic sensitivity testing, and to make recommendations for practitioners on the antibiotics of first choice. Inclusion criteria for the study included the animal being diagnosed with an odontogenic abscess which underwent surgery and was not pre-treated with an antibiotic. Inclusion criteria matched for 24 guinea pigs. Samples (pus, capsule and affected tooth/bone) for bacteriological examination were collected under sterile conditions during the surgical procedure. The most commonly isolated bacteria from abscesses of odontogenic origin were Bacteroides fragilis in 12.8 per cent (6/47) of cases, Pasteurella multocida in 10.6 per cent (5/47) and Peptostreptococcus anaerobius in 8.5 per cent (4/47). Aerobic bacterial species only were isolated in 29.2 per cent (7/24) of cases, anaerobic bacteria only were isolated in 33.3 per cent (8/24), and mixed infection with anaerobic and aerobic bacterial species was seen in 37.5 per cent (9/24). Aerobes (n=20) were sensitive to enrofloxacin and marbofloxacin in 100 per cent of samples, benzylpenicillin potassium (penicillin G, PNCG) in 90 per cent, cephalotin in 85 per cent, amoxicillin-clavulanate in 75 per cent, doxycycline in 70 per cent, gentamicin in 65 per cent and trimethoprim-sulfamethoxazole in 55 per cent. Anaerobes (n=27) were sensitive to amoxicillin-clavulanate in 100 per cent of cases, clindamycin in 96.3 per cent, metronidazole in 92.6 per cent, PNCG in 92.6 per cent and cephalotin in 74.1 per cent. As guinea pigs are strictly herbivorous animals, based on the results of this study the recommended antibiotic treatment for odontogenic abscesses is a combination of fluoroquinolones and metronidazole.

  15. Peritonsillar Abscess: Complication of Acute Tonsillitis or Weber's Glands Infection?

    Klug, Tejs Ehlers; Rusan, Maria; Fuursted, Kurt; Ovesen, Therese


    To review the literature concerning the 2 primary hypotheses put forth to explain the pathogenesis of peritonsillar abscess: "the acute tonsillitis hypothesis" (peritonsillar abscess is a complication of acute tonsillitis) and "the Weber gland hypothesis" (peritonsillar abscess is an infection of Weber's glands). PubMed, EMBASE. Data supporting or negating one hypothesis or the other were elicited from the literature. Several findings support the acute tonsillitis hypothesis. First, the 2 main pathogens in peritonsillar abscess have been recovered from pus aspirates and bilateral tonsillar tissues with high concordance rates, suggesting that both tonsils are infected in patients with peritonsillar abscess. Second, studies report signs of acute tonsillitis in the days prior to and at the time of peritonsillar abscess. Third, antibiotic treatment reduces the risk of abscess development in patients with acute tonsillitis. However, some findings suggest involvement of the Weber's glands in peritonsillar abscess pathogenesis. First, high amylase levels have been found in peritonsillar pus. Second, the majority of peritonsillar abscesses are located at the superior tonsillar pole in proximity of the Weber's glands. We propose a unified hypothesis whereby bacteria initially infect the tonsillar mucosa and spread via the salivary duct system to the peritonsillar space, where an abscess is formed. Our findings support the rationale for antibiotic treatment of patients with severe acute tonsillitis to reduce the risk of abscess development. Improved understanding of peritonsillar abscess pathogenesis is important for the development of efficient prevention strategies. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Full Text Available Spinal epidural abscess due to its varied presentation , poses a great challenge, more so in a healthy adult, without any predisposing factors. Early diagnosis and treatment is paramount, as late diagnosis and delayed treatment result in increased mortality and morbidity. In this case report, we are presenting a case of spinal extradural abscess in a healthy young adult without predisposing factors, provisionally diagnosed as extradural hematoma and early surgical intervention confirmed the diagnosis of spinal epidural abscess and prevented any devastating consequence

  1. CT detection and aspiration of abdominal abscesses.

    Haaga, J R; Alfidi, R J; Havrilla, T R; Cooperman, A M; Seidelmann, F E; Reich, N E; Weinstein, A J; Meaney, T F


    Computed tomography (CT) is effective in detecting intraabdominal abscesses. Loculations of fluid and extraluminal gas are clearly localized in relation to other organs. Of 22 abscess in this series, CT successfully detected 20; comparative information with gallium, techneticum, and ultrasound scans is presented. In addition to localizing these collections, CT can be used to guide needle aspiration and drainage procedures. Three sizes of needles were used to aspirate specimens and/or provide drainage. This was accomplished successfully in 12 of 14 CT-guided procedures.

    Ibis, Cem; Sezer, Atakan; Batman, Ali K; Baydar, Serkan; Eker, Alper; Unlu, Ercument; Kuloglu, Figen; Cakir, Bilge; Coskun, Irfan


    Brucellosis is a zoonotic infection that is transmitted from animals to humans by ingestion of infected food products, direct contact with an infected animal, or aerosol inhalation. The disease is endemic in many countries, including the Mediterranean basin, the Middle East, India, Mexico, Central and South America and, central and southwest Asia. Human brucellosis is a systemic infection with a wide clinical spectrum. Although hepatic involvement is very common during the course of chronic brucellosis, hepatic abscess is a very rare complication of Brucella infection. We present a case of hepatic abscess caused by Brucella, which resembled the clinical presentation of surgical acute abdomen.

  3. Rapidly Progressive Spontaneous Spinal Epidural Abscess

    Abdurrahman Aycan


    Full Text Available Spinal epidural abscess (SEA is a rare disease which is often rapidly progressive. Delayed diagnosis of SEA may lead to serious complications and the clinical findings of SEA are generally nonspecific. Paraspinal abscess should be considered in the presence of local low back tenderness, redness, and pain with fever, particularly in children. In case of delayed diagnosis and treatment, SEA may spread to the epidural space and may cause neurological deficits. Magnetic resonance imaging (MRI remains the method of choice in the diagnosis of SEA. Treatment of SEA often consists of both medical and surgical therapy including drainage with percutaneous entry, corpectomy, and instrumentation.

  4. Extensive spinal epidural abscess complicated with hydrocephalus

    Balan Corneliu


    Full Text Available Spinal epidural abscess is a rare but severe infection requiring prompt recognition in order to have a favorable outcome and appropriate treatment, mainly surgical. We present one of the largest extensions of such abscess in literature, involving the whole spine. No surgical treatment was tempted due to the involvement of 19 levels but antibiotics. The evolution of the lesion was complicated with hydrocephalus, by mechanism of cervical block of CSF flow, and needed first external derivation and later ventriculo-peritoneal drainage.

  6. Amebic liver abscess and polycystic liver disease

    Karan V. S. Rana


    Full Text Available Polycystic liver disease is a rare disorder which remains asymptomatic. Infection of cyst is a major complication and is usually pyogenic. We report a rare case of amebic liver abscess in a patient with polycystic liver disease. In our search we found one such case report. Clinical features and radiological findings are usually sufficient, but atypical history and the presence of multiple hepatic abscesses in CT scan delayed diagnosis in our case. Histopathology of the cyst wall and enzyme immunoassay asserted the diagnosis.

  7. Cerebral candida abscess in an infant

    Baradkar V


    Full Text Available Brain abscess is uncommon in the pediatric population. Here, we report one such case due to Candida albicans in one-year-old infant, without any predisposing factors. The child presented with progressively increasing size of head circumference. The diagnosis was confirmed by CT scan of brain and microbiological investigations on the drained pus material. The patient responded to combination of surgery (drainage and intravenous amphotericin B. Neurological development six months after hospital discharge was normal. The organism being a rare cause of cerebral abscess in pediatric population is reported here.

  8. [The anal fistula disease and abscess].

    Strittmatter, Bernhard


    There are two forms of anal fistulas arising from its pathogenesis: the acute stage is the abscess, whereas the chronic stage is the fistula in ano. The classification of the fistula in ano is named after Parks. Pathogenesis and classification are explained. For complete cure, every abscess needs precise examination to be able to show the course and shape of the fistula. The surgical procedure depends on the fistula tract. Most fistulas can be operated by means of a fistulotomy or fistulectomy. Recovery depends on locating the total fistula tract.

  9. Chest wall abscess due to Prevotella bivia

    Gwo-jong HSU; Cheng-ren CHEN; Mei-chu LAI; Shi-ping LUH


    Prevotella bivia is associated with pelvic inflammatory disease. A 77-year-old man developed a rapidly growing chest wall abscess due to P. Bivia within days. He underwent surgical resection of the infected area; his postoperative course was un-eventful. This is the first case of chest wall abscess due to P. Bivia infection. Its correct diagnosis cannot be underestimated be-cause fulminam infections can occur in aged or immunocompromised patients if treated incorrectly. Prompt, appropriate surgical management, and antibiotic therapy affect treatment outcome.

  10. Historical perspectives on the roots of the apical negative pressure irrigation technique in endodontics.

    Gutmann, James L; Zehnder, Matthias; Levermann, Vivian Manjarres


    The removal of the infectious process caused by an abscess in the periapical tissues was a challenge to dentists in the early part of the 20th century. While they recognized the need to debride the periapical tissues, the process was slow, tedious, and often fraught with failure that resulted in tooth extraction. However, with some creative ingenuity, an irrigation-suction apparatus was developed in the 1930s that enabled rapid and thorough debridement. This appliance went through multiple developmental permutations and was successful in achieving the desired goal. Interestingly, while the purpose of this device was a controlled periapical debridement through the root canal, and not necessarily a focus on a cleaning of the intricacies of the root canal system, the basic concept purported was similar to contemporary approaches used in root canal debridement today.

    Riadh Sadik; Evangelos Kalaitzakis; Anders Thune; Jan Hansen; Claes J(o)nson


    AIM: To compare the results for endoscopic ultrasound (EUS)-guided drainage of clear fluid pancreatic pseudocysts with the results for abscess drainage. METHODS: All patients referred for endoscopic drainage of a fluid collection were prospectively included. The outcome was recorded. RESULTS: Altogether 26 pseudocysts or abscesses were treated in 25 (6 female) patients. One endoscopist performed the procedures. Non-infected pseudocysts were present in 15 patients and 10 patients had infected fluid collections. The cyst size ranged between 28 cm × 13 cm and 5 cm × 5 cm. The EUS drainage was successful in 94% of the pseudocysts and in 80% of the abscesses (P = 0.04). The complication rate in pseudocysts was 6% and in abscesses was 30% (P = 0.02). Recurrence of a pseudocyst occurred in one patient (4%) after 6 mo; the patient was successfully retreated. CONCLUSION: EUS-guided drainage of pseudocysts is associated with a higher success rate and a lower complication rate compared with abscess drainage.

    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 sixtyseven 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 ofKlebsiella 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) andmultiple 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 APACHEⅡ scores are poor prognostic factors. Early surgical intervention should be encouraged when these risk factors are present.

  13. Long-term results of modified sandwich repair of aortic root in 151 patients with acute type A aortic dissection.

    Tang, Yangfeng; Liao, Zilin; Han, Lin; Tang, Hao; Song, Zhigang; Xu, Zhiyun


    Acute type A aortic dissection frequently induces aortic root disease; however, the optimal surgical strategy for aortic root dissection remains a challenge. The objective of this study was to introduce a novel technique for reconstruction of type A dissection to improve patient prognosis. We performed a retrospective review of 791 consecutive patients with acute type A aortic dissection between January 2003 and July 2015. Among these patients, 151 were selected (72% men, age 51.7 ± 9.8 years) to have the modified sandwich repair of aortic root dissection. The in-hospital mortality rate of the 151 patients was 6.6% (10/151). During a mean follow-up period of 52.7 ± 28.6 months, the survival rate was 100, 89.1 and 69.7% at 1, 5 and 10 years, respectively. Echocardiography and computed tomographic angiography were performed every year to monitor the pathological change in the aortic root. Freedom from severe aortic regurgitation at 5 years was 100%. No patients required reintervention due to dissection or pseudoaneurysm of the proximal aortic root. Aortic valve resuspension and repair of the sinus of Valsalva with the modified sandwich technique using Teflon felt strips for acute type A dissection could be reliable and effective.

  14. Boron deficiency results in early repression of a cytokinin receptor gene and abnormal cell differentiation in the apical root meristem of Arabidopsis thaliana.

    Abreu, Isidro; Poza, Laura; Bonilla, Ildefonso; Bolaños, Luis


    The development of Arabidopsis thaliana was dramatically altered within few hours following boron (B) deprivation. This effect was particularly evident in the apical root meristem. The essentiality of boron in plants has been clearly linked to its structural role in the cell wall, however the diversity and rapidity alterations of plant organogenesis when the micronutrient is absent suggest that B deficiency could also affect gene regulation during plant development. Therefore, the effect of B deficiency on cell elongation, apical root meristem cell division, and early differentiation of root tissues was investigated in A. thaliana seedlings. Dark-growth experiments indicated that hypocotyl elongation was inhibited 2 days after removing B, but apical root growth ceased almost immediately following B deprivation. Detection of cycline B1 by GUS staining of a promoter-reporter construct revealed that low B led to a reduced zone of cell division. The expression of CRE1/WOL/AHK4, encoding an integral membrane protein with histidine kinase domain that mediates cytokinin signaling and root xylem differentiation, was inhibited under B deficiency resulting in arrested xylem development at the protoxylem stage. Because the transition from cell division to cell differentiation in apical root meristems is controlled by cytokinins, this result support the hypothesis that signaling mechanisms during cell differentiation and organogenesis are highly sensitive to B deficiency, and together with previous reports that link the micronutrient with auxin or ethylene control of root architecture, suggests that B could play a role in regulation of hormone mediated early plant development signaling.

    Full Text Available Intratonsillar abscess is a rare complication of acute tonsillitis. It is a rarely diagnosed infection occurring in both children and adults. Herein, we present a case of intratonsillar abscess in a 25-year-old female patient, who was managed by needle aspiration which is a minimally invasive procedure and it is low cost, safe and effective along with antibiotic therapy. The aspiration of the pus from the tonsil confirms the diagnosis of intratonsillar abscess. So intratonsillar abscesses are uncommon, but should be considered in the differential diagnosis of peritonsillar abscess and tonsillitis.

  16. Orbital abscess from dacryocystitis caused by Morganella morganii.

    Carruth, Bryant P; Wladis, Edward J


    A 22-year-old female with multiple developmental abnormalities stemming from cardiofaciocutaneous syndrome presented with a recurrent orbital abscess 2 years after orbitotomy with drainage of an abscess of presumed hematogenous-origin. During careful intraoperative examination the abscess was seen to directly extend from the lacrimal sac. Cultures were taken and grew Morganella morganii, a Gram negative rod uncommon in ocular and periocular infections. To the author's knowledge, this microorganism has been reported in only one previous case of orbital abscess and underscores the need for organism identification and antibiotic sensitivity analysis in cases of orbital abscess, particularly those with extension from dacryocystitis.

  17. An Unusual Case of Acute Epiglottic Abscess

    Tanthry Deepalakshmi


      Incision and drainage was performed under general anaesthesia after haematological investigations. Patient was extubated the next day, and was discharged after two days, also oral antibiotics, and analgesics were prescribed. Patient was reviewed after 2 weeks, and indirect laryngoscopy revealed a normal epiglottis.Although pharyngitis is the most common cause of sore throat in adults, acute epiglottitis must be considered in differential diagnosis when there is unrelenting throat pain, and minimal objective signs of pharyngitis. Epiglottic abscess formation is more common in adults than children. They most commonly occur as a complication of acute pharyngitis or with abscess of lingual tonsil .The abscess most frequently comes to a point on or near the lingual surface of the epiglottis. Streptococcus was isolated more frequently. Other organisms reported were Haemophilus influenzae, E.coli, Pseudomonas, Micro- coccus catarrhalis, Pneumococci. In our case, there were no preceding symptoms of acute pharyngitis. Risk factors include adult age at onset, diabetes mellitus, trauma, presence of a foreign body, and immune- compromised state. This case is unusual because of the absence of above risk factors. Incision and drainage under general anaesthesia is the treatment of choice. To the author’s knowledge, very few cases of acute epiglottic abscesses have been reported in the literature. This case is unusual because there are no preceding symptoms of pharyngitis or tonsillitis, and no association of risk factors like diabetes mellitus, trauma, foreign body or immunocompromised state.

    Yi, Liao; Lihua, Qiu; Xianming, Diao; Qiyong, Gong


    Hepatic abscesses and hepatic metastasis are common diseases. However, hepatic abscesses seldom occur in patients with hepatic metastases. We describe a case of a 67-year-old female patient with abdominal pain in the right upper quadrant. Magnetic resonance imaging revealed several lesions, with the largest lesion displaying features of both hepatic pyogenic abscess and liver metastasis. These features included iso- or hypointense signaling on T1WI and T2WI, hyperintense signaling on diffusion weighted imaging of the thick wall, and mixed hyperintense signal in the center on DWI, as well as dramatic and irregular peripheral enhancement was detected on LAVA dynamic contrast scanning. Aspiration and culture of the largest lesions revealed Klebsiella pneumoniae and a pathologic diagnosis of adenocarcinoma. At this point, the patient admitted a history of colon adenocarcinoma 9 years ago treated with hemicolectomy. Therefore, this patient was considered to have a hepatic pyogenic abscesses complicated by hepatic metastasis. The patient began treatment for the responsible pathogens and underwent chemoembolization of the liver lesions. In special cases, we could attempt to pursue a more detailed search for coexistence of microorganism infection and tumor.

  1. Iliopsoas abscess: a re-emerging clinical entity not to be forgotten.

    Al-Hilli, Z


    Iliopsoas abscesses are relatively rare clinical entities. They present with subtle and non-specific symptoms and as a result the diagnosis is often delayed, leading to significant morbidity and mortality. With an increasing number of immunocompromised patients in the population the prevalence of this condition is set to rise. Therefore, early diagnosis and appropriate management remain a challenge for clinicians. We present three patients with iliopsoas abscesses, two of which were primary and one of which was secondary to Crohn\\'s disease. The average age of patients was 59 years and both patients with primary psoas abscesses were male. All presented with non-specific symptoms. Psoas sign was present in only one patient. CT confirmed the diagnosis in all cases. Treatment consisted of appropriate antibiotic cover and associated percutaneous drainage. The psoas abscess that was secondary to underlying Crohn\\'s disease was subsequently treated with surgical excision of the affected segment of bowel and lavage of the abscess cavity. A high index of suspicion is required to ensure the accurate and early diagnosis of this rare clinical entity. Abdominal CT scanning remains the gold standard for diagnosis. Management is with appropriate antibiotics and adequate drainage. This can be achieved by either percutaneous or surgical drainage. Such treatment can reduce the overall morbidity and mortality of this condition.

  2. Human Listeriosis Presenting as Breast Abscess: Report of a Rare Case


    An abscess is defined as a collection of pus in various tissues of the body including skin and other organs. Abscesses most commonly are formed on the skin under the armpits, groin areas, and rectal areas. Most abscesses involve microbial infections with few remaining sterile. The treatment of abscesses includes both medical and surgical intervention. In the era of multidrug resistance, isolation and identification of the causative microbe and testing for antimicrobial susceptible patterns assume greater significance for the better management of patients, thereby reducing the resultant morbidity and mortality. Listeria spp. are a group of aerobic and non-spore forming gram-positive bacilli. They are present in the environment, soil, and water. Listeria spp. have also been noted to be present as a normal intestinal flora of animals. They are known for their ability to thrive under both cold and hot environmental conditions. Human infections with Listeria spp. have not been frequently reported, mostly because of the difficulty in laboratory identification and complex clinical presentations. In humans, Listeria spp. have been frequently responsible for food poisoning and neonatal meningitis. Although not considered as a classic pathogen, Listeria spp. are associated with infections in elderly people, pregnant women, newborns, and persons with weakened immune systems. This report presents a case of breast abscess caused by Listeria spp. in a young lactating female belonging to rural India. PMID:28289572

    Asai, Nobuhiro; Ohkuni, Yoshihiro; Kaneko, Norihiro; Aoshima, Masahiro; Yamazaki, Ikuo; Kawamura, Yasutaka, E-mail: [Kameda Medical Center, Chiba (Japan)


    Combination therapy of CT-guided percutaneous drainage and antibiotics is the first-line treatment for abscesses. Its effectiveness has been demonstrated. However, the therapeutic impact of this procedure for infection treatment has never been reported. We retrospectively analyzed all 47 patients who received CT-guided percutaneous drainage for infection treatment. Patients' characteristics, pathogens isolated, antibiotics administered, technical and clinical outcomes, complications related to this procedure and therapeutic impacts were investigated. Patients were 26 males and 21 females. The mean age was 63.5 years ({+-}18.7). The diseases targeted were 19 retroperitoneal abscesses, 18 intraabdominal abscesses, three pelvic abscesses, and seven others. As for technical outcomes, all of the 54 procedures (100%) were successful. As for clinical outcomes, 44 (93.6%) were cured and three patients (6.4%) died. No complications related to this procedure were found in this study. A total of 42 patients (88%) had a change in the management of their infection as a result of CT-guided percutaneous drainage, such as selection and discontinuation of antibiotics. In conclusion, CT-guided percutaneous drainage is a safe and favorable procedure in the treatment of deep tissue abscesses. Therapeutic impact of these procedures helped physicians make a rational decision for antibiotics selection. (author)

    Braun, Ueli; Malbon, Alexandra; Kochan, Manon; Riond, Barbara; Janett, Fredi; Iten, Cornelia; Dennler, Matthias


    In cattle, the prognosis of brain abscess is unfavourable and treatment is therefore not recommended. To the knowledge of the authors, there has been no report of successful treatment of a brain abscess in cattle.This report describes the clinical, computed tomographic and postmortem findings in a Holstein-Friesian bull with a hypophyseal abscess. The main clinical findings were generalised ataxia, ptyalism, prolapse of the tongue, dropped jaw, dysphagia, head tilt and unilateral ptosis. Cerebrospinal fluid evaluation revealed 2437 leukocytes/µl and severe pleocytosis. CT examination of the head showed a cavitary lesion consistent with an abscess in the hypophysis. Treatment consisted of gentamicin and flunixin meglumine for 3 days and amoxicillin for 40 days. The neurological signs resolved within 8 days of the start of treatment. The bull was slaughtered 11 months later because of infertility, and a postmortem examination was carried out. Histologically, a mild chronic non suppurative meningoencephalitis restricted to the ventral diencephalon was diagnosed. In addition, there was mild to moderate multifocal chronic lymphoplasmacytic hypophysitis with mild multifocal fibrosis. This case report stresses the significance of CT in confirming the clinical and laboratory diagnosis of central nervous system disorders in cattle and for localising brain lesions. Treatment of the brain abscess resulted, with respect to the central nervous disorder, in a successful outcome and was encouraging considering that most cases have an unfavourable prognosis.

    Full Text Available Objectives: The purpose of the present study was to investigate the reliability of both periapical radiographs and orthopantomograms for exact detection of tooth root protrusion in the maxillary sinus by correlating the results with cone beam computed tomography.Material and methods: A database of 1400 patients scanned with cone beam computed tomography (CBCT was searched for matching periapical (PA radiographs and orthopantogram (OPG images of maxillary premolars and molars. Matching OPG images datasets of 101 patients with 628 teeth and PA radiographs datasets of 93 patients with 359 teeth were identified. Four observers assessed the relationship between the apex of tooth root and the maxillary sinus per tooth on PA radiographs, OPG and CBCT images using the following classification: root tip is in the sinus (class 1, root tip is against the sinus wall (class 2 and root tip is not in the sinus (class 3.Results: Overall correlation between OPG and CBCT images scores was 50%, 26% and 56.1% for class 1, class 2 and class 3, respectively (Cohen’s kappa [weighted] = 0.1. Overall correlation between PA radiographs and CBCT images was 75.8%, 15.8% and 56.9% for class 1, class 2 and class 3, respectively (Cohen’s kappa [weighted] = 0.24. In both the OPG images and the PA radiographs datasets, class 1 correlation was most frequently observed with the first and second molars.Conclusions: The results demonstrated that both periapical radiographs and orthopantomograms are not reliable in determination of exact relationship between the apex of tooth root and the maxillary sinus floor. Periapical radiography is slightly more reliable than orthopantomography in determining this relationship.

    CHEN Fan


    Full Text Available ObjectiveTo analyze the clinical data of Klebsiella pneumoniae liver abscess (KPLA, and to provide a reference for early diagnosis and proper treatment. MethodsThe etiological features of 156 patients with bacterial liver abscess (BLA and positive culture results who were hospitalized in The First Hospital Affiliated to Nanjing Medical University from March 2009 to July 2015 were analyzed retrospectively. According to the culture results, BLA patients were divided into KPLA group (81 patients and non-KPLA (NKPLA group (61 patients, and other positive strains including Escherichia coli were found in the other 14 patients with positive culture results for Klebsiella pneumoniae. The clinical, laboratory, and imaging data of KPLA and NKPLA were compared. The t-test was applied for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was applied for continuous data with skewed distribution between groups; the chi-square test or Fisher′s exact test was applied for comparison of categorical data between groups. ResultsThe most common pathogenic bacteria for BLA were Klebsiella pneumonia. In comparison with the NKPLA group, the KPLA group had a significantly higher proportion of male patients (χ2=4.50, P=0.03, a significantly higher proportion of patients with diabetes (χ2=27.28,P<0.001, and a significantly lower proportion of patients who complained of abdominal pain (χ2=5.24, P=0.02. In the aspects of underlying diseases, the prevalence of biliary tract diseases, previous abdominal surgery, and a history of intraperitoneal tumors showed significant differences between the NKPLA group and the KPLA group (χ2=18.38, 20.87, and 21.68, all P<0.001. As for laboratory examination, the NKPLA group had a significantly greater reduction in hemoglobin compared with the KPLA group (t=4.903, P<0.001. In terms of imaging examination, most BLA patients showed a single lesion in the right lobe of the liver, but

  12. Thigh Abscess Caused by Yersinia enterocolitica in an Immunocompetent Host

    Purva Gumaste


    Full Text Available Yersinia enterocolitica is primarily a gastrointestinal tract pathogen known to cause gastroenteritis, although it may produce extra-intestinal infections like sepsis and its sequelae. However, primary cutaneous infections are extremely rare. We present a case of Y. enterocolitica thigh abscess in an immunocompetent adult. The portal of entry is unclear in this case. He did many outdoor activities that involved skin injuries and exposure to soil and contaminated water. Hence, direct inoculation as a result of exposure to contaminated water is postulated in the absence of evidence for a gastrointestinal route of infection.

  13. Pancreatic and Colonic Abscess Formation Secondary to HELLP Syndrome

    James M. O’Brien


    Full Text Available Preeclampsia and the variant HELLP syndrome are systemic conditions associated with vascular changes resulting in vasoconstriction. Most commonly, patients present with elevated blood pressure and proteinuria, with a background of complaints such as headache, scotoma, and right upper quadrant pain. The systemic vascular changes experienced can target any organ system, oftentimes with more than one organ system being involved. We present the case of a patient admitted with HELLP syndrome who subsequently developed multisystem organ dysfunction, including placental abruption, disseminated intravascular coagulopathy, acute renal failure, colitis, abdominal ascites, pancreatitis, and the development of pancreatic and colonic abscesses.

  14. Hyponatremia as the Presenting Feature of a Pituitary Abscess in a Calf

    Jamie L. Stewart


    Full Text Available A 2-month-old Simmental heifer presented for acute onset of neurological behavior. Laboratory tests confirmed the presence of hyponatremia, hypochloremia, and hypokalemia that improved with intravenous fluid therapy. Despite an initial cessation of neurological signs, symptoms re-emerged, and the heifer was euthanized due to poor prognosis. A pituitary abscess (Trueperella pyogenes was observed on gross necropsy, suggesting that the effects of panhypopituitarism (inappropriate anti-diuretic hormone (ADH, adrenocorticotropic hormone (ACTH, and/or thyroid-stimulating hormone (TSH secretion may have resulted in the clinical findings. Pituitary abscess syndrome carries a poor prognosis due to the inability to penetrate the area with systemic antibiotic therapy. These findings highlight the unusual clinical presentations that may occur following pituitary abscess syndrome in cattle that practitioners need to consider when determining prognosis.

  15. Amebic lung abscess with coexisting lung adenocarcinoma: a unusual case of amebiasis.

    Zhu, Hailong; Min, Xiangyang; Li, Shuai; Feng, Meng; Zhang, Guofeng; Yi, Xianghua


    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.

  16. German S3 guidelines: anal abscess and fistula (second revised version).

    Ommer, Andreas; Herold, Alexander; Berg, Eugen; Fürst, Alois; Post, Stefan; Ruppert, Reinhard; Schiedeck, Thomas; Schwandner, Oliver; Strittmatter, Bernhard


    The incidence of anal abscess and fistula is relatively high, and the condition is most common in young men. This is a revised version of the German S3 guidelines first published in 2011. It is based on a systematic review of pertinent literature. Cryptoglandular abscesses and fistulas usually originate in the proctodeal glands of the intersphincteric space. Classification depends on their relation to the anal sphincter. Patient history and clinical examination are diagnostically sufficient in order to establish the indication for surgery. Further examinations (endosonography, MRI) should be considered in complex abscesses or fistulas. The goal of surgery for an abscess is thorough drainage of the focus of infection while preserving the sphincter muscles. The risk of abscess recurrence or secondary fistula formation is low overall. However, they may result from insufficient drainage. Primary fistulotomy should only be performed in case of superficial fistulas. Moreover, it should be done by experienced surgeons. In case of unclear findings or high fistulas, repair should take place in a second procedure. Anal fistulas can be treated only by surgical intervention with one of the following operations: laying open, seton drainage, plastic surgical reconstruction with suturing of the sphincter (flap, sphincter repair, LIFT), and occlusion with biomaterials. Only superficial fistulas should be laid open. The risk of postoperative incontinence is directly related to the thickness of the sphincter muscle that is divided. All high anal fistulas should be treated with a sphincter-saving procedure. The various plastic surgical reconstructive procedures all yield roughly the same results. Occlusion with biomaterial results in lower cure rate. In this revision of the German S3 guidelines, instructions for diagnosis and treatment of anal abscess and fistula are described based on a review of current literature.

  17. Bacterial pathogens induce abscess formation by CD4(+) T-cell activation via the CD28-B7-2 costimulatory pathway.

    Tzianabos, A O; Chandraker, A; Kalka-Moll, W; Stingele, F; Dong, V M; Finberg, R W; Peach, R; Sayegh, M H


    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.

  18. Sensitivity of computed tomography in detection of perirectal abscess.

    Caliste, Xzabia; Nazir, Shazia; Goode, Terral; Street, James H; Hockstein, Michael; McArthur, Karina; Trankiem, Christine T; Sava, Jack A


    Most patients with anorectal abscess are diagnosed clinically based on pain, erythema, warmth, and fluctuance. Some patients, however, present with subtle or atypical signs. CT is easily accessible and is commonly used for diagnosis and delineation of anorectal abscess. The purpose of this study is to determine the sensitivity of CT scan in detecting perirectal abscesses and to see if immune status impacts the accuracy of CT. A retrospective study was conducted to identify patients from 2000 to 2009 with International Classification of Diseases, 9th Revision code 566 (anal or rectal abscess). Patients included had a CT scan less than 48 hours before drainage. Patients with CT-positive abscess were compared with patients with CT-negative abscess. Patients were categorized as either immunocompetent or immunosuppressed based on documentation of diabetes mellitus, cancer, human immunodeficiency virus, or end-stage renal disease. One hundred thirteen patients were included in this study. Seventy-four (65.5%) were male and the average age was 47 years. Eighty-seven of 113 (77%) patients were positive on CT for anorectal abscess. Sixty of 113 (53%) patients included in this study were immunocompromised. CT missed 26 of 113 (23%) patients with confirmed perirectal abscess. Eighteen (69%) of these patients were immunocompromised compared with CT-positive patients (42 [48%], P = 0.05). The overall sensitivity of CT in identifying abscess was 77 per cent. CT lacks sensitivity in detecting perirectal abscess, particularly in the immunocompromised patient.

  19. Legionellosis and Lung Abscesses: Contribution of Legionella Quantitative Real-Time PCR to an Adapted Followup

    G. Descours


    Full Text Available We report a case of severe Legionnaires' disease (LD complicated by a lung abscess in an immunocompetent patient who required ECMO therapy and thoracic surgery. The results of repeated Legionella quantitative real-time PCR performed on both sera and respiratory samples correlated with the LD severity and the poor clinical outcome. Moreover, the PCR allowed for the detection of Legionella DNA in the lung abscess specimen, which was negative when cultured for Legionella. This case report provides a logical basis for further investigations to examine whether the Legionella quantitative PCR could improve the assessment of LD severity and constitute a prognostic marker.

    Emmanouil Liarmakopoulos


    Full Text Available The rarest subtype of malignant fibrous histiocytoma (MFH is the inflammatory type, which due to its peculiar clinical presentation may mimic an infectious process such as an abscess. The rarity of this disease and the unique features of its presentation may mislead the surgeon with consequent catastrophic results for the patient. In this study, a case report of a 65-year-old female patient with a soft-tissue inflammatory MFH presenting as a lumbar abscess and a review of the current literature are presented.

  2. Nontropical pyomyositis complicated with spinal epidural abscess in a previously healthy child

    Mohamed Boulyana


    Full Text Available Background: Pyomyositis (PM, a rare pyogenic infection that involves skeletal muscles, if not immediately diagnosed, can be fatal. Most notably, this results in spinal epidural abscess (SEA in typically unhealthy individuals. Case description: We present a very rare nontropical PM complicated with SEA in a previously healthy child revealed by Magnetic resonance imaging (MRI. Our patient recovered without complications 5 years after abscess drainage and antibiotics. Conclusion: PM remains a challenge to clinicians and should be considered in the differential diagnosis of musculoskeletal pain. MRI is the investigation of choice of spinal infection and should be undertaken at an early stage.

This case documents a male in his seventh decade who presented with multiple peri-anal collections. The abscess cavity had caused necrosis of the internal sphincter muscles resulting in faecal incontinence. Biopsies were conclusive for diffuse large B-cell lymphoma. A de-functioning colostomy was performed and the patient was initiated on CHOP-R chemotherapy. Anal lymphoma masquerading as a ...

  6. Intratesticular Abscess in a Solitary Testicle: The Case for Testicle Sparing Management

    Uwais B. Zaid


    Full Text Available We present the case of a 24-year-old immunocompromised man with an intratesticular abscess. The patient presented with one week of left scrotal pain and swelling. Workup included scrotal ultrasonography which revealed a large fluid collection within the tunica albuginea of the left testis. Surgical exploration of the left testis evacuated a significant amount of purulent fluid. The residual viable testicular parenchyma was salvaged. Intraoperative cultures grew Morganella morganii. Follow-up ultrasonography showed resolution of the testicular fluid collection, and the patient was discharged home with oral antibiotics. Intratesticular abscesses are a rare clinical entity which often result in orchiectomy.

  9. Subperiostal Orbital Abscess and Frontal Epidural Abscess Due to Sinusitis: A Case Report

    Burak Ulaş


    Full Text Available A seventeen-year-old girl was admitted to our clinic with complaint of rubor, swelling, and pain on the left upper eyelid. Her medical history revealed that she had received high-dose oral steroid treatment for one week for the diagnosis of acute angioedema in another clinic. On ophthalmologic examination, her left upper eyelid had edema, swelling, and hyperemia. Additionally, she had restriction in up-gaze in the left eye. Her best-corrected visual acuity was 0.7. The patient’s computerized tomography revealed ethmoidal, maxillary and frontal sinusitis, as well as subperiostal orbital abscess, and frontal epidural abscess. Intravenous antibiotic treatment has been arranged. Due to persistence of the clinical signs, surgical drainage of the abscesses has been performed. Following, she has been discharged from the hospital on oral antibiotic treatment. Postoperatively, at the first-month visit, the left eye’s up-gaze restriction was recovered, and visual acuity was improved to 1.0. If a patient presents with eyelid swelling, differential diagnosis should be performed carefully before making the decision to start steroid treatment. Sinusitis, which is seen frequently in clinical practice, should be kept in mind due to its potential to cause orbital abscess, epidural abscess, and intracranial complications.

  10. Splenectomy Correlates With Increased Risk of Pyogenic Liver Abscess: A Nationwide Cohort Study in Taiwan

    Shih-Wei Lai


    Full Text Available Objectives: Little is known about the risk of pyogenic liver abscess in patients with splenectomy. We explored the relationship between splenectomy and pyogenic liver abscess in Taiwan. Methods: We conducted a nationwide cohort analysis using the hospitalization dataset of the Taiwan National Health Insurance Program. We included 17 779 subjects aged 20–84 years who underwent splenectomy in 1998 to 2010 (splenectomy group and 70 855 randomly selected subjects without splenectomy (non-splenectomy group. Both groups were matched by sex, age, other comorbidities, and hospitalization year of receiving splenectomy. The incidence of pyogenic liver abscess at the end of 2011 was measured. The multivariable Cox proportional hazard regression model was used to estimate the hazard ratios and 95% confidence intervals for pyogenic liver abscess associated with splenectomy and other comorbidities. Results: The overall incidence rate was 3.75-fold higher in the splenectomy group than that in the non-splenectomy group (2.15 vs 0.57 per 1000 person-years; 95% confidence interval, 3.57–3.94. After controlling for potential confounding factors, the adjusted hazard ratio of pyogenic liver abscess was 3.89 in subjects with splenectomy (95% confidence interval, 3.20–4.72 when compared with subjects without splenectomy. In further analysis, the hazard ratio markedly increased to 14.34 for those with splenectomy and having any of the assessed comorbidities, including alcoholism, biliary stone, chronic kidney disease, chronic liver diseases, and diabetes mellitus (95% confidence interval, 10.61–19.39. Conclusions: Patients with splenectomy are at an increased risk of developing pyogenic liver abscess, particularly when they have comorbid conditions.

  11. Pilot study to evaluate the role of Mycoplasma species in cat bite abscesses.

    Torres-Henderson, Camille; Hesser, Jeff; Hyatt, Doreene R; Hawley, Jennifer; Brewer, Melissa; Lappin, Michael R


    Mycoplasma species are common inhabitants of the feline oral cavity, and so likely contaminate many cat bite abscesses. The objectives of this study were to determine whether Mycoplasma species are common contaminants of cat bite abscesses and whether they are are associated with β-lactam-resistant clinical disease. Twenty-six privately owned cats with clinical evidence of an abscess suspected to be from a cat bite were included in the study. Samples from each cat were evaluated by aerobic and anaerobic culture, as well as Mycoplasma species culture and polymerase chain reaction (PCR). All cats were initially treated with appropriate wound management and were administered an antibiotic of the β-lactam class (amoxicillin, amoxicillin clavulanate or cefovecin sodium). Mycoplasma species DNA was amplified by PCR from 4/26 samples (15.4%); one of these cases was concurrently culture positive. Adequate DNA for sequencing was present for 2/4 positive PCR samples; one was most homologous with Mycoplasma felis, and the other was most homologous with Mycoplasma equigenitalium and Mycoplasma elephantis. Of the 26 cats, 25 responded to the initial treatment by day 7. The cat that failed initial treatment was positive for M equigenitalium or M elephantis DNA on days 0 and 12, and ultimately responded to administration of enrofloxacin and clindamycin. The results suggest that while Mycoplasma species can contaminate cat bite abscesses, routine wound management and β-lactam antibiotic therapy is adequate for treatment in most cases of abscess. However, as Mycoplasma species infections do not respond to β-lactam class antibiotic therapy, these organisms should be on the differential list for cats with abscesses that fail treatment with this antibiotic class.

    Westyn Branch-Elliman

    Full Text Available OBJECTIVES: To determine the health and economic burdens of post-partum Staphylococcus aureus breast abscess. STUDY DESIGN: 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. RESULTS: 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. CONCLUSIONS: 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.

  13. A Rare Complication of Brucellosis: Testicular Abscess

    Ümit Gul


    Full Text Available Brucellosis is a zoonosis caused by Brucella species. Brucella epididymo-orchitis had been reported in up to 20% of patients with brucellosis. This case was a male patient who developed Brucella epidiymo-orchitis and testicular abscess. He had fever, arthralgia and his right epididymis and right testicle were enlarged and tender. Ultrasound evaluation showed hypertrophy of the right epididymis and testis and moreover hypoechoic area within the testis. Brucella serology was positive and the patient did not respond completely to treatment with streptomycin, doxycycline, and rifampicina. Unilateral orchidectomy was decided. In areas where brucella infection is endemic brucella epididymo-orchitis should be considered in the differential diagnosis. Effective and rapid treatment is important. It should be noted that these patients may develop testicular abscess.

  14. An interesting case of cerebral abscess.

    Rafiq, Muhammad Khizar


    An immigrant from Romania was referred to the neurosurgical unit with a cerebral abscess. On examination she was cyanosed and had clubbing of her fingers. A cardiovascular system examination revealed a systolic murmur heard all over the precordium. However, the diagnosis was not congenital cyanotic heart disease. The patient had a history of frequent nosebleeds and had multiple telangiectases on her body, leading to the diagnosis of hereditary haemorrhagic telangiectasia (HHT). A search was carried out for the presence of arteriovenous malformations in internal organs. Large arteriovenous malformations were found in the lungs, causing her cyanosis due to right-to-left shunting of blood and cerebral abscess due to paradoxical septic embolisation into cerebral circulation.

  15. Retroperitoneal abscess: an extra-abdominal manifestation.

    Mallia, Alvin James; Ashwood, Neil; Arealis, George; Galanopoulos, Ilias


    Retroperitoneal abscesses are unusual occurrences with occult and insidious presentations. There is often a lack of abdominal signs, leading to delays in drainage and high mortality rates. We report a case of thigh emphysema in an 88-year-old patient with diabetes. Prior to admission the patient reported a vague 4-week history of left thigh pain and an inability to fully weight bear. She presented to our emergency department with sepsis and acute kidney impairment. An X-ray of her left femur revealed widespread gas between muscular planes. A retroperitoneal abscess involving the left renal fossa, psoas, iliacus and upper thigh muscles was revealed on an urgent CT scan. The patient was transferred to intensive care unit (ICU) and underwent an emergency drainage. Despite ICU the patient died 2 days after admission.

  16. [Pelvic actinomycosis abscess and intrauterine device].

    Ko-Kivok-Yun, P; Charasson, T; Halasz, A; Fournié, A


    A case of association between IUD and a left tubal actinomycotic abscess is presented. The 45 year old patient was wearing an IUD for five years. The symptomatology was mainly that of pelvic pain with an associated mass in the left iliac fossa. The working diagnosis was that of a digestive tumor or an adnexal mass. The surgical procedure allowed to identify an inflammatory reaction with a pseudotumoral abscess formation in the left fallopian tube. The etiology was confirmed by the pathology and bacteriology reports. Treatment consists in surgical extirpation of the infected structures and long term antibacterial therapy. Actinomycosis is a rare but potentially serious pelvic disease. It may involve various organs and readily takes on the aspect of tumor formation.

  17. Treatment of anal fistula and abscess.

    Pigot, F


    The glands of Hermann and Desfosses, located in the thickness of the anal canal, drain into the canal at the dentate line. Infection of these anal glands is responsible for the formation of abscesses and/or fistulas. When this presents as an abscess, emergency drainage of the infected cavity is required. At the stage of fistula, treatment has two sometimes conflicting objectives: effective drainage and preservation of continence. These two opposing constraints explain the existence of two therapeutic concepts. On one hand the laying-open of the fistulous tract (fistulotomy) in one or several operative sessions remains the treatment of choice because of its high cure rates. On the other hand surgical closure with tract ligation or obturation with biological components preserves sphincter function but suffers from a higher failure rate. Copyright © 2014.

  18. Radiofrequency ablation of a misdiagnosed Brodie's abscess.

    Chan, Rs; Abdullah, Bjj; Aik, S; Tok, Ch


    Radiofrequency ablation (RFA) therapy is recognised as a safe and effective treatment option for osteoid osteoma. This case report describes a 27-year-old man who underwent computed tomography (CT)-guided percutaneous RFA for a femoral osteoid osteoma, which was diagnosed based on his clinical presentation and CT findings. The patient developed worsening symptoms complicated by osteomyelitis after the procedure. His clinical progression and subsequent MRI findings had led to a revised diagnosis of a Brodie's abscess, which was further supported by the eventual resolution of his symptoms following a combination of antibiotics treatment and surgical irrigations. This case report illustrates the unusual MRI features of osteomyelitis mimicking soft tissue tumours following RFA of a misdiagnosed Brodie's abscess and highlights the importance of a confirmatory histopathological diagnosis for an osteoid osteoma prior to treatment.

  19. Scintigraphic findings in a Brodie's abscess.

    Silva, F; Laguna, R; Acevedo, M; Ruíz, C; Orduña, E


    A 9-year-old girl had a 6-month history of left hip pain. Radiographs of the left hip showed a metaphyseal osteolytic lesion with sclerotic borders in the femoral neck. Tc-99m MDP bone imaging and a Ga-67 scan showed focal areas of increased activity in the left femoral neck. These areas of increased uptake corresponded to a lytic area on x-rays, which was due to a Brodie's abscess. The combination of Tc-99m MDP bone and Ga-67 imaging has been widely used in the confirmation of bone infection, increasing the accuracy in the diagnosis of osteomyelitis. However, nuclear scintigraphy has not been previously reported in the confirmation of a Brodie's abscess.

  20. High REDOX RESPONSIVE TRANSCRIPTION FACTOR1 Levels Result in Accumulation of Reactive Oxygen Species in Arabidopsis thaliana Shoots and Roots.

    Matsuo, Mitsuhiro; Johnson, Joy Michal; Hieno, Ayaka; Tokizawa, Mutsutomo; Nomoto, Mika; Tada, Yasuomi; Godfrey, Rinesh; Obokata, Junichi; Sherameti, Irena; Yamamoto, Yoshiharu Y; Böhmer, Frank-D; Oelmüller, Ralf


    Redox Responsive Transcription Factor1 (RRTF1) in Arabidopsis is rapidly and transiently upregulated by H2O2, as well as biotic- and abiotic-induced redox signals. RRTF1 is highly conserved in angiosperms, but its physiological role remains elusive. Here we show that inactivation of RRTF1 restricts and overexpression promotes reactive oxygen species (ROS) accumulation in response to stress. Transgenic lines overexpressing RRTF1 are impaired in root and shoot development, light sensitive, and susceptible to Alternaria brassicae infection. These symptoms are diminished by the beneficial root endophyte Piriformospora indica, which reduces ROS accumulation locally in roots and systemically in shoots, and by antioxidants and ROS inhibitors that scavenge ROS. More than 800 genes were detected in mature leaves and seedlings of transgenic lines overexpressing RRTF1; ∼ 40% of them have stress-, redox-, ROS-regulated-, ROS-scavenging-, defense-, cell death- and senescence-related functions. Bioinformatic analyses and in vitro DNA binding assays demonstrate that RRTF1 binds to GCC-box-like sequences in the promoter of RRTF1-responsive genes. Upregulation of RRTF1 by stress stimuli and H2O2 requires WRKY18/40/60. RRTF1 is co-regulated with the phylogenetically related RAP2.6, which contains a GCC-box-like sequence in its promoter, but transgenic lines overexpressing RAP2.6 do not accumulate higher ROS levels. RRTF1 also stimulates systemic ROS accumulation in distal non-stressed leaves. We conclude that the elevated levels of the highly conserved RRTF1 induce ROS accumulation in response to ROS and ROS-producing abiotic and biotic stress signals.

  1. Comparison of needle aspiration and vacuum-assisted biopsy in the ultrasound-guided drainage of lactational breast abscesses

    Kang, Yun Dan; Kim, You Me [Dankook University College of Medicine, Cheonan (Korea, Republic of)


    The purpose of this study was to compare needle aspiration and vacuum-assisted biopsy in the ultrasound-guided treatment of lactational breast abscesses. Between January 2005 and December 2014, a total of 74 patients presented with lactational breast abscesses. Thirty of these patients underwent treatment with antibioticsalone, while the remaining 44 lactating women with breast abscesses were treated with needle aspiration (n=25) or vacuum-assisted biopsy (n=19). Age, duration of lactation, abscess diameter, pus culture results, the number of interventions, the healing time, and the cure rate were reviewed and compared between these two groups. The Student's t test and the chi-square test were used to compare the variables. No significant difference was found in the cure rate between the needle aspiration group (22/25, 88%) and the vacuum-assisted biopsy group (18/19, 94.7%) (P=0.441). However, the mean healing time was significantly shorter in the vacuum-assisted biopsy group (6.7 days) than in the needle aspiration group (9.0 days) (P=0.001). Vacuum-assisted biopsy is a viable option for the management of lactational breast abscesses and was found to lead to a shorter healing time than needle aspiration. However, further study is necessary to establish the clinical efficacy of vacuum-assisted biopsy in the management of lactational breast abscesses.

  2. Effect of rehabilitation on a patient suffering from a tuberculous brain abscess with Gerstmann's syndrome: case report.

    Kuo, Chih-Lan; Lo, Sui-Foon; Liu, Chun-Lin; Chou, Chia-Hui; Chou, Li-Wei


    There are few reports in the literature of tuberculous brain abscess. Tuberculous brain abscess usually occurs in an immunocompromised host. Almost all previously documented cases have involved acquired immune deficiency syndrome. We encountered a 53-year-old right-handed immunocompetent male who was initially suspected of having a cerebrovascular accident due to acute-onset right hemiparesis and paresthesia. A tentative diagnosis of brain tumor versus brain abscess was made on imaging studies. The patient was finally diagnosed with a tuberculous brain abscess based upon deterioration on imaging and a positive tuberculosis culture. The tuberculous brain abscess was located in the left parietal lobe, which resulted in Gerstmann's syndrome and right-sided apraxia. Stereotactic surgery was performed. He was also given antituberculosis chemotherapy and comprehensive rehabilitation. Considerable improvement was noted after rehabilitation. The patient even returned to a normal life and work. Our case demonstrates that an aggressive intensive inpatient rehabilitation program combined with stereotactic surgery and effective antituberculosis therapy play an important role in improving the outcome for patients with tuberculous brain abscess, Gerstmann's syndrome, and right-sided apraxia.

  3. Intramedullary tubercular abscess with syrinx formation

    Mohd Khalid


    Full Text Available Intramedullary spinal cord tubercular abscess with involvement of whole cord is a rare entity that too with syrinx formation following disseminated meningitis. Accurate diagnosis requires a high index of suspicion with clinical history and imaging features for a favorable outcome. Here-in we present a similar case with tubercular etiology which was also associated with syrinx formation and has not been reported previously in the literature up to the author′s knowledge.

  4. Intra-abdominal gout mimicking pelvic abscess

    Chen, Chia-Hui; Chen, Clement Kuen-Huang [Kaohsiung Veterans General Hospital, Department of Radiology, Kaohsiung (Taiwan); National Yang-Ming University, School of Medicine, Taipei (Taiwan); Yeh, Lee-Ren; Pan, Huay-Ban; Yang, Chien-Fang [Kaohsiung Veterans General Hospital, Department of Radiology, Kaohsiung (Taiwan)


    Gout is the most common crystal-induced arthritis. Gouty tophi typically deposit in the extremities, especially toes and fingers. We present an unusual case of intrapelvic tophaceous gout in a patient suffering from chronic gouty arthritis. CT and MRI of the abdomen and pelvic cavity disclosed calcified gouty tophi around both hips, and a cystic lesion with peripheral enhancement in the pelvic cavity along the course of the iliopsoas muscle. The intra-abdominal tophus mimicked pelvic abscess. (orig.)

  5. Clinical Practice Guidelines for Cerebral Abscess Treatment

    Danny Barrueta Reyes


    Full Text Available Clinical Practice Guidelines for Cerebral Abscess Treatment. It has been defined as a festering process caused by any germ and placed inside the cerebral parenchyma; this is a diagnostic and therapeutic challenge for surgeons and general doctors since the clinical and radiological manifestations are often imprecise. This document describes its etiological agents, clinical presentation, diagnosis and treatment. It includes assessment guidelines focused on the most important aspects to be accomplished.

  6. Peritonsillar abscess: clinical aspects of microbiology, risk factors, and the association with parapharyngeal abscess.

    Klug, Tejs Ehlers


    . Conclusions on causality cannot be drawn from this retrospective study, but the pathophysiology behind the increased risk of PTA in smokers may be related to, previously shown, alterations in the tonsillar, bacterial flora or the local and systemical inflammatory and immunological milieu. Studying all 1,620 patients with PTA in Aarhus County from 2001 to 2006 and using population data for Aarhus County for the same six years, age- and gender-stratified mean annual incidence rates of PTA were calculated. The incidence of PTA was highly related to age and gender. The seasonal variation of PTA was insignificant. However, the microbiology of PTA fluctuated with seasons: GAS-positive PTA cases were significantly more prevalent in the winter and spring compared to the summer, while FN-positive PTA patients exhibited a more even distribution over the year, but with a trend towards higher prevalence in the summer than in the winter. In a series of 63 patients with PPA, we found that 33 (52%) patients had concomitant PTA. This association between PPA and PTA was much higher than previously documented. We therefore suggest that combined tonsillectomy and intrapharyngeal incision in cases where PTA is present or suspected. The results of our routine cultures could not support a frequent role of FN in PPA. Based on our findings suggesting that FN is a frequent pathogen in PTA, we recommend clindamycin instead of a macrolide in penicillin-allergic patients with PTA. Furthermore, cultures made from PTA aspirates should include a selective FN-agar plate in order to identify growth of this bacterium. Recent studies of sore throat patients document an association between recovery of FN and acute tonsillitis. Studying the bacterial flora of both tonsils in study II, we found almost perfect concordance between the bacterial findings of the tonsillar core at the side of the abscess and contralaterally. This finding suggests that FN is not a subsequent overgrowth phenomenon after abscess

  7. Evidence-based Homoeopathy: A case of corneal abscess

    Sandeep Sudhakar Sathye


    Full Text Available Corneal abscess is a circumscribed collection of pus within the layers of cornea. It is usually endogenous in origin and commonly found near the limbal blood vessels close to corneal margin. Treatment in modern medicine is use of local and systemic antibiotics. Homoeopathy has mentioned medicines for corneal abscess. A case reported was a female of 68 years of age suffering from symptoms of redness, dull pain, and foreign body sensation in the right eye and was diagnosed as corneal abscess. The homoeopathic medicine Hepar sulphuris 200C was prescribed on the basis of pathology. Abscess was reduced considerably within 5 days and it was absorbed completely in 21 days. No recurrence of abscess was observed thereafter. Ocular photographs during follow-up visits have provided documentary evidence about the effectiveness of homoeopathic Hepar sulphuris 200C in corneal abscess.

  8. Citrobocter kasori spinal epidural abscess: a rare occurrence.

    Kumar, Ashok; Jain, Pramod; Singh, Pritish; Divthane, Rupam; Badole, C M


    Pyogenic spinal epidural abscess Is an uncommon Infectious occurrence. Clinical prospects of pyogenic spinal epidural abscess are graver if not promptly diagnosed and treated appropriately. A case of spinal epidural abscess has been presented with sinus tract formation at L4-L5 level, of pyogenic aetiology that progressed to paraplegia over the course of the disease. MRI pointed towards an epidural abscess extending from T12 vertebral level to S1 vertebral level. Surgical decompression in the form of laminectomy and evacuation of pus was done and antibiotics were given according to culture and sensitivity. Histopathological analysis revealed the acute suppurative nature of the abscess. Citrobacter kasori was isolated on pus culture. Pyogenic epidural abscess with causative organism being Citrobacter kasori has least been documented.

  9. Sonographic findings of coccygeal abscess in the neonates

    Bae, Jun Gi; Kim, Ji Hye; Chun Seok; Lee, Young Seok; Kim, Hyung Sik; Kim, Sang Hi [Chungang Gil Hospital, Incheon (Korea, Republic of)


    The purpose of this study was to report the sonographic findings of neonatal coccygeal abscess, previously not described. Eighteen neonates (5-18 days old) presented with swelling in the coccygeal area and by either open drainage (n=13) or follow-up after antibiotic therapy (n=5), this was diagnosed as coccygeal abscess. We retrospectively reviewed the size, shape, location, echo pattern and marginal characteristics of the abscesses, as seen on sonography, as well as their intradural content and relationship with the spine. Additional MR images (n=5) were separately reviewed. Coccygeal abscesses were confined to the subcutaneous fat layer and were either isoor hypoechoic compared with surrounding fat. In neonates, abscess formation in the coccygeal area is possible and coccygeal abscess should therefore be included in the differentiation of coccygeal masses. (author). 7 refs., 3 figs.

  10. Pyogenic liver abscess associated with large colonic tubulovillous adenoma

    Hsueh-Chou Lai; Cho-Yu Chan; Cheng-Yuan Peng; Chih-Bin Chen; Wen-Hsin Huang


    Pyogenic liver abscesses usually occur in association with a variety of diseases. Rarely, liver abscess has been reported as the presenting manifestation of colonic tubulovillous adenoma. We report two cases of pyogenic liver abscess without hepatobiliary disease or other obvious etiologies except that one had a history of diabetes mellitus (DM). The pathogen in the patient with DM was Klebsiella pneumonia (KP). In both of the patients, ileus developed about two to three weeks after the diagnosis of liver abscess. Colonoscopy revealed large polypoid tumors with pathological findings of tubulovillous adenoma in both cases. Two lessons were learned from these two cases: (1) an underlying cause should be aggressively investigated in patients with cryptogenic liver abscess; (2) DM could be one of the etiologies but not necessarily the only cause of KP liver abscess.

  11. A cerebral abscess at first internist glance.

    Ribeiro, Rita; Patrício, Catarina; Valejo Coelho, Margarida Moura; Brotas, Vítor


    A 73-year-old man was transferred to the neurosurgery ward, with a presumptive diagnosis of cerebral abscess. The case was also discussed with the internists as internal medicine consultants. The neurosurgeons pointed out a right temporal lobe abscedated lesion on CT, but we noticed that the hypodense attenuation that usually surrounds the abscess wall (vasogenic oedema) extended to a broader, well-delimitated area, suggesting medium cerebral artery territory. The patient had left-sided hemiplegia with a confusional state and low-grade fever. Considering possible haematogenous dissemination, an echocardiography was performed, confirming mitral endocarditis. Blood cultures and aspirated pus isolated Escherichia coli. Investigating the patient's medical history, we learned he had been submitted to bladder catheterisation 7 weeks before for acute urinary retention due to benign prostatic hyperplasia, and empirically medicated for urinary tract infection. E. coli had also been isolated in a urine specimen at the time. The clinical history of the patient cancelled the pathogenesis of cerebral abscess. 2015 BMJ Publishing Group Ltd.

    Jeong, Woo Shin; Choi, Sung Youn; Jeong, Eun Haeng; Bang, Ki Bae; Park, Seung Sik; Lee, Dae Sung; Park, Dong Il; Jung, Yoon Suk


    Klebsiella pneumoniae (K. pneumoniae) can at times cause invasive infections, especially in patients with diabetes mellitus and a history of alcohol abuse. A 61-year-old man with diabetes mellitus and a history of alcohol abuse presented with abdominal and anal pain for two weeks. After admission, he underwent sigmoidoscopy, which revealed multiple ulcerations with yellowish exudate in the rectum and sigmoid colon. The patient was treated with ciprofloxacin and metronidazole. After one week, follow up sigmoidoscopy was performed owing to sustained fever and diarrhea. The lesions were aggravated and seemed webbed in appearance because of damage to the rectal mucosa. Abdominal computed tomography and rectal magnetic resonance imaging were performed, and showed a perianal and perirectal abscess. The patient underwent laparoscopic sigmoid colostomy and perirectal abscess incision and drainage. Extended-spectrum beta-lactamase-producing K. pneumoniae was identified in pus culture. The antibiotics were switched to ertapenem. He improved after surgery and was discharged. K. pneumoniae can cause rapid invasive infection in patients with diabetes and a history of alcohol abuse. We report the first rare case of proctitis and perianal abscess caused by invasive K. pneumoniae infection.

  13. [Brodie abscess. Primarily misinterpreted as traumatic lesion].

    Nicolajsen, K; Jørgensen, P S; Tørholm, C


    Two case histories are presented. In the first, a 49 year-old man fell on his right hip. He was able to walk, but because of pain he came to our emergency room. Radiographics gave an impression of an undislocated intertrochanteric fracture, scintigraphy confirmed the suspicion. There were no signs of infection. On starting osteosynthesis with the drilling of a hole in the lateral cortex, discharge of pus was observed and curettage of the abscess cavity was performed. In the second, a 21 year-old man hit his right knee against a table. Because of pain he was admitted to hospital. Primary signs of a lesion of the lateral meniscus were found and arthroscopy was scheduled. When readmitted we found signs of an infection and X-ray revealed a Brodie's abscess in the proximal tibia. The abscess cavity was opened and curettage was performed. Radiographics, scintigraphics, blood parameters and pathological and microbiological investigations revealed primary chronic osteomyelitis in both patients. Antibiotic therapy was instituted and six weeks after primary operation bone transplantation was performed. The further course was uncomplicated.

  14. Ultrasound-guided surgical drainage of face and neck abscesses.

    Yusa, H; Yoshida, H; Ueno, E; Onizawa, K; Yanagawa, T


    An ultrasound-guided surgical drainage technique in which grey-scale and colour Doppler ultrasonography were combined is described. The technique was performed for eight deep subcutaneous abscesses subsequent to odontogenic infection, and provided easy detection and accurate, reliable penetration of abscesses that were difficult to locate by physical examination. Colour Doppler ultrasonography is particularly useful for differentiating blood vessels from the static space of abscesses.

  15. Emphysematous liver abscess in diabetic patient: two cases report

    Rhim, Hyun Chul; Koo, Ja Hong; Kim, Sung Tae; Kim, Yong Soo; Koh, Byung Hee; Cho, On Koo [College of Medicine, Hanyang University, Seoul (Korea, Republic of)


    There has not been any report on massive air-containing liver abscess in diabetic patients, although emphysematous cholecystitis or pyelonephritis is a well-known complication in them. Authors report two cases of emphysematous liver abscess in diabetic patient, which showed typical findings of massive air-containing hepatic abscess on ultrasonography and computed tomography, but very poor prognosis in spite of immediate and successful percutaneous drainage procedure.

  16. Brodie's abscess of the cuboid bone: a case report.

    The case of a patient with Brodie's abscess of the cuboid bone and who presented with a painful and swollen right foot is described. The patient was treated successfully by surgical evacuation of the abscess and with antibiotics. To the authors' knowledge, Brodie's abscess of the cuboid bone has not been reported previously. The clinical presentation and diagnostic difficulties which may be encountered are discussed.

  17. Brodie's abscess of the femoral neck simulating osteoid osteoma.

    Gulati, Yash; Maheshwari, Aditya V


    Subacute osteomyelitis (Brodie's abscess) is essentially a problem of diagnosis, and there may be considerable difficulty in distinguishing it from other benign and malignant bone lesions. Though reported in the metaphyseal region of the femur, Brodie's abscess is rarer in the femoral neck. The authors present a case of Brodie's abscess in the femoral neck, which clinico-radiologically simulated an osteoid osteoma. Retrospectively, the presence of a cortical sinus tract should have aroused suspicion.

  18. Comparing root architectural models

    Schnepf, Andrea; Javaux, Mathieu; Vanderborght, Jan


    Plant roots play an important role in several soil processes (Gregory 2006). Root architecture development determines the sites in soil where roots provide input of carbon and energy and take up water and solutes. However, root architecture is difficult to determine experimentally when grown in opaque soil. Thus, root architectural models have been widely used and been further developed into functional-structural models that are able to simulate the fate of water and solutes in the soil-root system (Dunbabin et al. 2013). Still, a systematic comparison of the different root architectural models is missing. In this work, we focus on discrete root architecture models where roots are described by connected line segments. These models differ (a) in their model concepts, such as the description of distance between branches based on a prescribed distance (inter-nodal distance) or based on a prescribed time interval. Furthermore, these models differ (b) in the implementation of the same concept, such as the time step size, the spatial discretization along the root axes or the way stochasticity of parameters such as root growth direction, growth rate, branch spacing, branching angles are treated. Based on the example of two such different root models, the root growth module of R-SWMS and RootBox, we show the impact of these differences on simulated root architecture and aggregated information computed from this detailed simulation results, taking into account the stochastic nature of those models.

  19. Clinical and CT findings of Klebsiella liver abscess: comparison with non-Klebsiella liver abscess

    Woo, Young Geun; Kim, Man Deuk; Yoon, Sang Wook; Kim, Hee Jin [Bundang CHA General Hospital, Seongnam (Korea, Republic of); Kim, Hyun [Daejon St. Mary' s Hospital, Taejon (Korea, Republic of); Lee, Kang Mun [St. Vincent Hospital, Suwon (Korea, Republic of); Lee, Eun Ja [Myungji Hospital, Goyang (Korea, Republic of)


    To analyse the clinical features and CT findings of pyogenic liver abscess due to Klebsiella pneumoniae, and to compare the findings with those of cases in which abscesses were caused by other pathogens. Twenty-one cases of pyogenic liver abscess were assigned to either the Klebsiella or the non-Klebsiella group, and the patients' past medical history and intra-abdominal abnormalities such as calculus or malignancy were reviewed. Laboratory data such as alkaline phosphatase (ALT), SGOT and SGPT levels were analyzed, and on the basis of the CT findings, decisions were reached as to (a) whether abscesses were single or multiple contiguous or discontiguous, uniloculated or multiloculated; and (b) the presence or absence of gas, hepatic parenchymal enhancement, peripheral rim enhancement, and extrahepatic abnormality. For statistical analysis, fisher's exact test was used. Among 21 abscesses, Klebsiella pneumoniae was the most common pathogen (n=11). The others were Pseudomonas (n=3), E.coli (n=2), Enterococcus (n=2), G. (+) cocci (n=2) and polymicrobial (n=1). Diabetes mellitus was more common among patients in the Klebsiella group, among whom a multiloculated single cavity was a frequent finding. Five patients in the non-Klebsiella group experienced biliary tract obstruction, which was not demonstrated in the Klebsiella group. Hepatic parenchymal enhancement was more common in the non-Klebsiella group. In case of pyogenic liver disease, especially where diabates mellitus is involved, Klebsiella pneumoniae is a major pathogen. Significant CT findings of Klebsiella liver abscess included a multiloculated single cavity, rare biliary tract obstruction, and little hepatic parenchymal enhancement.

  20. Septic arthritis of the knee associated with calf abscess.

    Izumi, Masashi; Ikeuchi, Masahiko; Tani, Toshikazu


    Septic arthritis associated with extra-articular abscess is rare. We report on 2 non-rheumatic patients with septic arthritis of the knee associated with calf abscess. Magnetic resonance imaging showed a distinct leakage pathway from the knee joint in each patient. One was a ruptured popliteal cyst (posteromedial). Another was a pathologic popliteus hiatus (posterolateral). These patients underwent open drainage of the calf abscess via a small incision, followed by arthroscopic debridement of the knee. Careful palpation of the lower leg, followed by magnetic resonance imaging and needle aspiration, is important to exclude a possible extra-articular abscess regardless of the presence of a popliteal cyst.

  1. Right adrenal abscess -- an unusual complication of acute apendicitis.

    Dimofte, Gabriel; Dubei, Liviu; Lozneanu, Lili-Gabriela; Ursulescu, Corina; Grigora Scedil, Mihai


    Acute appendicitis represents one of the most frequent abdominal emergencies encountered in everyday surgical practice. Local infectious complications are not unusual and retroperitoneal abscesses after acute retrocaecal appendicitis have been previously described. The authors present the case of a 22-years-young female patient, admitted for a right iliac fossa abscess, secondary to gangrenous appendicitis. A right adrenal mass 35/40 mm was revealed during preoperative ultrasound evaluation, which evolved in an adrenal abscess that spontaneously drained 10 days after appendectomy and retrocecal drainage. Adrenal abscesses are exceptionally rare, with only a few cases being reported in the literature, but none of these after acute appendicitis.

  2. Head and neck cancers masquerading as deep neck abscesses.

    Soon, Sue Rene; Kanagalingam, Jeevendra; Johari, Shirish; Yuen, Heng Wai


    Deep neck space abscesses are common otolaryngological emergencies, and prompt incision and drainage is the treatment of choice. Head and neck cancers often present with cervical metastases that may become secondarily infected. Clinical presentation is similar to a deep neck abscess. Surgical drainage of such collections has implications on subsequent treatment. In this case series, we describe six cases with this unusual presentation that were subsequently found to have a head and neck malignancy, and where three patients had their abscesses treated surgically. We aim to raise awareness of this unusual presentation of a head and neck carcinoma, and to avoid a potential pitfall in the management of deep neck abscess.

  3. Unusual liver abscess secondary to ingested foreign body: laparoscopic management



    Liver abscess is a cause of febrile abdominal pain and usually the origin of a liver abscess is ascending cholangitis, hemathological diffusion, via the portal vein or the hepatic artery, or superinfection of necrotic tissue. Solitary pyogenic abscess with no obvious systemic cause may be secondary to a local event such as the migration of an ingested foreign body. We report the case of a solitary liver abscess caused by an ingested foreign body, a fish bone, migrated through the gastric wall into the left lobe. PMID:26017106




    Full Text Available ABSTRACT: Various aerobic and anaerobic bacteria have been r eported as causative agents of brain abscess but only a few cases of enterococcal brain abscesses have been reported. We report a case of enterococcal brain abscess of otoge nic origin in a 35 year old male who was known case of chronic suppurative otitis media (CSOM and cholesteotoma of the right ear. The abscess material culture yielded an isolate which w as identified as Enterococcus faecium by standard biochemical reaction. The isolate was sens itive to penicillin, ampicillin, gentamicin, vancomycin, ofloxacin, lincomycin, and cloxacillin.

  5. Iris abscess a rare presentation of intravenous drug abuse associated Candida endophthalmitis

    Jonathan Pierce


    Conclusions and importance: An iris abscess is a rare clinical presentation of intravenous drug use-associated endogenous endophthalmitis and as a result may present a diagnostic challenge as it requires a high level of clinical suspicion and a detailed social history to elicit the drug abuse. Early diagnosis and aggressive therapy is the key to better visual outcomes in these patients.

  6. Early secondary suture versus healing by second intention of incisional abscesses

    Hermann, G G; Bagi, P; Christoffersen, I


    A controlled trial was set up to compare the treatment of wound abscesses, occurring after laparotomy, with either early secondary suture combined with cefuroxime and metronidazole given intravenously or by healing by second intention. The secondary suture was performed two days after wound...... drainage and resulted in a significant reduction (p less than 0.01) in healing time without complications. No reinfections occurred....

  7. [Infracondylar abscess formation: a rare complication of local anesthesia].

    Dojcinovic, I; Hugentobler, M; Richter, M


    Ninety percent of oro-facial infections arise from a dental origin. The remaining 10% are the consequence of oro-pharyngeal, cutaneous or iatrogenic problems, such as in the present case. A 24-year-old patient consulted the emergency room because of a left mandibular swelling, accompagnied by trismus. Four days earlier, extraction of the 38 was performed under inferior alveolar nerve block anesthesia. A first drainage by vestibular approach was performed under general anesthesia. Because of the absence of improvement, a CT-scan was performed and an abscess localized at the base of the condyle, surrounding the posterior margin of the mandible, very high above the lingula. Outcome was favourable after a second surgery. Formation of an abscess very high above the lingula, around the condylar neck is rarely reported in the literature. In this patient it was certainly a complication resulting from the injection of local anesthesic with a vasoconstrictor. CT-scan should be performed to guide diagnosis in the event of an unusual course after the first surgical procedure and an adequate antibiotic regimen.

  8. Percutaneous drainage of abscess in the treatment of emphysematous pyelonephritis

    Jung, Jin Yong; Jeong, Yong Yeon; Kim, Jae Kyu; Park, Seung Jei; Park, Jin Gyoon; Kang, Heoung Keun [Chonnam Univ. School of Medicine, Kwangju (Korea, Republic of); Roh, Byung Suk [Wonkwang Univ. School of Medicine, Iksan (Korea, Republic of)


    To assess the usefulness of percutaneous drainage of abscess in the treatment of emphysematous pyelonephritis. Ten cases of nine patients with emphysematous pyelonephritis were percutaneously drained. All were suffering from diabetes mellitus. The procedure was performed under fluoroscopic guidance in nine cases and US guidance in one case in which bilateral multiloculated abscesses were present in the perirenal space. The results were classified as cure, partial success, recurrence, or failure. The mean drainage period and complication were analyzed. Eight cases were cured, and there was one case success. In one case, who had diffuse renal parenchymal destruction without perirenal fluid collection, the treatment failed. The longest drainage period was 45 days, in a case of re-insertion due to incidental catheter removal; the mean was 23 days. Bacteremia in one case was cured with antibiotic therapy which lasted two days. In diabetic patients, percutaneous drainage of obscess is thought to be a safe and effective method for the treatment of emphysematous pyelonephritis, and is one that does not involve diffuse destruction of renal parenchyma.

  9. Diagnostic tests for amoebic liver abscess: comparison of enzyme - linked immunosorbent assay (Elisa and counterimmunoelectrophoresis (CIE

    Marcos I. Restrepo


    Full Text Available The liver abscess is the most frequent extraintestinal complication of intestinal amoebiasis: its diagnosis is suggested by the clinical picture but it must be confirmed by paraclinic tests. Themost stringent diagnosis requires identification of E. histolytica. But this is possible only in a few cases. Serological tests greatly improve the diagnosis of this severe complication of amoebiasis. We compared the Enzyme Linfed Immunosorbent Assay and the Counterimmunoeletrophoresis techniques. Both techniques were used to detect amoebic antibodies in 50 control patients, 30 patients with liver abscess and 30 patients with intestinal amoebiasis. All the sera from control patients gave negative results iin both techniques. When analysing the sera from patients with intestinal amoebiasis, 10% of them were positive by ELISA but non by CIE. The sera of patients with liver abscess, we found that 90% were positive by the ELISA method and 66.6% by the CIE technique. In patients with amoebic liver abscess, the results showed that the ELISA was more sensitive than the CIE, as it presented a higher sensitivity (100% than that of the CIE technique (66%.

  11. Successful operative management of an upper lumbar spinal canal stenosis resulting in multilevel lower nerve root radiculopathy

    Shearwood McClelland


    Full Text Available Lumbar stenosis is a common disorder, usually characterized clinically by neurogenic claudication with or without lumbar/sacral radiculopathy corresponding to the level of stenosis. We present a case of lumbar stenosis manifesting as a multilevel radiculopathy inferior to the nerve roots at the level of the stenosis. A 55-year-old gentleman presented with bilateral lower extremity pain with neurogenic claudication in an L5/S1 distribution (posterior thigh, calf, into the foot concomitant with dorsiflexion and plantarflexion weakness. Imaging revealed grade I spondylolisthesis of L3 on L4 with severe spinal canal stenosis at L3-L4, mild left L4-L5 disc herniation, no stenosis at L5-S1, and no instability. EMG revealed active and chronic L5 and S1 radiculopathy. The patient underwent bilateral L3-L4 hemilaminotomy with left L4-L5 microdiscectomy for treatment of his L3-L4 stenosis. Postoperatively, he exhibited significant improvement in dorsiflexion and plantarflexion. The L5-S1 level was not involved in the operative decompression. Patients with radiculopathy and normal imaging at the level corresponding to the radiculopathy should not be ruled out for operative intervention should they have imaging evidence of lumbar stenosis superior to the expected affected level.

  12. Prevention of Evisceration or Enucleation in Endogenous Bacterial Panophthalmitis with No Light Perception and Scleral Abscess

    Chen, Kuan-Jen; Chen, Yen-Po; Chao, An-Ning; Wang, Nan-Kai; Wu, Wei-Chi; Lai, Chi-Chun; Chen, Tun-Lu


    Panophthalmitis is the most extensive ocular involvement in endophthalmitis with inflammation in periocular tissues. Severe inflammation of the anterior and posterior segments is frequently accompanied by corneal opacity, scleral abscess, and perforation or rupture. Enucleation or evisceration was the only remaining viable treatment option when all options to salvage the eye had been exhausted. The purpose of this retrospective study is to examine the outcomes of patients with endogenous bacterial panophthalmitis, no light perception and scleral abscess who were treated with multiple intravitreal and periocular injections of antibiotics and dexamethasone. Evaluation included spreading of infection to contiguous or remote sites, following evisceration or enucleation, and sympathetic ophthalmia. Eighteen patients were diagnosed with EBP, with liver abscesses in eight patients, retroperitoneal infection in four, pneumonia in two, infective endocarditis in one, cellulitis in one, drug abuse in one, and mycotic pseudoaneurysm in one. Culture results were positive for Klebsiella pneumoniae in 12 patients, Streptococcus spp. in three, Pseudomonas aeruginosa in one, Escherichia coli in one, and Staphylococcus aureus in one. The average number of periocular injections was 2.2, and the average number of intravitreal injections was 5.8. No eye required evisceration or enucleation and developed the spreading of infection to contiguous or remote sites during the follow-up. No sympathetic ophthalmia was observed in the fellow eye of all patients. Prevention of evisceration or enucleation in patients with EBP, NLP and scleral abscess can be achieved by multiple intravitreal and periocular injections of antibiotics and dexamethasone.

  13. Peroxynitrite and Peroxiredoxin in the Pathogenesis of Experimental Amebic Liver Abscess

    Judith Pacheco-Yepez


    Full Text Available The molecular mechanisms by which Entamoeba histolytica causes amebic liver abscess (ALA are still not fully understood. Amebic mechanisms of adherence and cytotoxic activity are pivotal for amebic survival but apparently do not directly cause liver abscess. Abundant evidence indicates that chronic inflammation (resulting from an inadequate immune response is probably the main cause of ALA. Reports referring to inflammatory mechanisms of liver damage mention a repertoire of toxic molecules by the immune response (especially nitric oxide and reactive oxygen intermediates and cytotoxic substances released by neutrophils and macrophages after being lysed by amoebas (e.g., defensins, complement, and proteases. Nevertheless, recent evidence downplays these mechanisms in abscess formation and emphasizes the importance of peroxynitrite (ONOO−. It seems that the defense mechanism of amoebas against ONOO−, namely, the amebic thioredoxin system (including peroxiredoxin, is superior to that of mammals. The aim of the present text is to define the importance of ONOO− as the main agent of liver abscess formation during amebic invasion, and to explain the superior capacity of amoebas to defend themselves against this toxic agent through the peroxiredoxin and thioredoxin system.

  15. Do neutrophils play a role in establishing liver abscesses and distant metastases caused by Klebsiella pneumoniae?

    Lin, Jung-Chung; Chang, Feng-Yee; Fung, Chang-Phone; Yeh, Kuo-Ming; Chen, Chiung-Tong; Tsai, Yu-Kuo; Siu, L Kristopher


    Serotype K1 Klebsiella pneumoniae is a major cause of liver abscesses and endophthalmitis. This study was designed to identify the role of neutrophils in the development of distant metastatic complications that were caused by serotype K1 K. pneumoniae. An in vitro cellular model was used to assess serum resistance and neutrophil-mediated killing. BALB/c mice were injected with neutrophils containing phagocytosed K. pneumoniae. Serotype K1 K. pneumoniae was significantly more resistant to serum killing, neutrophil-mediated phagocytosis and intra-cellular killing than non-K1 isolates (pneutrophils containing phagocytosed serotype K1 K. pneumoniae led to abscess formation in multiple sites including the subcutaneous tissue, lung, and liver, whereas no abscess formation was observed in mice injected with non-K1 isolates. The resistance of serotype K1 K. pneumoniae to complement- and neutrophil-mediated intracellular killing results in the dissemination of K. pneumoniae via the bloodstream. Escape from neutrophil intracellular killing may contribute to the dissemination and establishment of distant metastases. Thus, neutrophils play a role as a vehicle for helping K. pneumoniae and contributing to the establishment of liver abscess and distant metastatic complications.

  16. Successful Treatment of a Large Pelvic Abscess Using Intraluminal VAC: A Case Report.

    Aras, Abbas; Celik, Sebahattin; Kiziltan, Remzi; Yilmaz, Özkan; Kotan, Çetin


    The most feared complication of the surgical treatment of rectal cancer is anastomotic leakage, which is related to high rates of mortality and morbidity. Here, we present a patient who could not be treated with surgical drainage but treated by intraluminal Vacuum Associated Closure (VAC). A 34-year-old male patient was treated for rectal cancer by low anterior resection, colorectal anastomosis, and diverting ileostomy following neoadjuvant CRT. The patient reported with a postoperative anastomotic disruption and a large pelvic abscess. Due to the continuation of foul-smell drainage inspite of perianal incision and drainage, intraluminal VAC was applied and the pelvic abscess and the foul-smell were successfully treated. The presence of an adequate anal sphincter tonus is a disadvantage in anastomotic leakage, since it prevents the emptying of the intestinal content and also precludes the drainage of the pelvic abscess. The endoluminal application of VAC, similar to the results of application of VAC in open wounds, has been demonstrated to decrease fibrin and necrotic tissue in the pelvic cavity and increase granulation tissue. VAC, which has long been used in the treatment of open wounds, is a promising method in the treatment of large pelvic abscesses due to anastomotic leakage following rectum resection.

  17. Risk of Liver Abscess Formation in Patients with Prior Biliary Intervention Following Yttrium-90 Radioembolization

    Cholapranee, Aurada; Houten, Diana van; Deitrick, Ginna; Dagli, Mandeep; Sudheendra, Deepak; Mondschein, Jeffrey I.; Soulen, Michael C., E-mail: [University of Pennsylvania, Division of Interventional Radiology (United States)


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

  18. Ileocecal masses in patients with amebic liver abscess: Etiology and management

    Sri Prakash Misra; Vatsala Misra; Manisha Dwivedi


    AIM: To assess the causes of ileocecal mass in patients with amebic liver abscess.METHODS: Patients with amebic liver abscess and ileocecal mass were carefully examined and investigated by contrast-enhanced CT scan followed by colonoscopy and histological examination of biopsy materials from lesions during colonoscopy.RESULTS: Ileocecal masses were found in seventeen patients with amebic liver abscess. The cause of the mass was ameboma in 14 patients, cecal tuberculosis in 2 patients and adenocarcinoma of the cecum in 1 patient. Colonic ulcers were noted in five of the six (83%) patients with active diarrhea at presentation. The ileocecal mass in all these patients was ameboma. Ulcers were seen in only one of the 11 (9%) patients without diarrhea. The difference was statistically significant from the group with diarrhea (P< 0.005).CONCLUSION: Ileocecal mass is not an uncommon finding in patients with amebic liver abscess. Although,the ileocecal mass is due to ameboma formation in most cases, it should not be assumed that this is the case in all patients. Colonoscopy and histological examination of the target biopsies are mandatory to avoid missing a more sinister lesion.

  19. Pyogenic Liver Abscess Associated with Septic Pulmonary Embolism

    Por-Wen Yang


    Conclusion: There is diagnostic value in performing a chest CT scan in diabetic patients who have liver abscess plus abnormal CXR findings with multiple ill-defined peripheral round densities, in order to detect SPE, which has a relatively poor outcome in patients with liver abscess.

  20. Porphyromonas gingivalis causing brain abscess in patient with recurrent periodontitis.

    Rae Yoo, Jeong; Taek Heo, Sang; Kim, Miyeon; Lee, Chang Sub; Kim, Young Ree


    We report an extremely rare case of Porphyromonas gingivalis causing brain abscess in a patient with recurrent periodontitis. The patient presented with right-sided homonymous hemianopsia and right hemiparesis. Emergent surgical drainage was performed and antibiotics were administered. P. gingivalis was identified from the anaerobic culture of the abscess. The clinical course of the patient improved with full recovery of the neurologic deficit.

  1. Infrahyoid spread of deep neck abscess: anatomical consideration.

    Ojiri, H; Tada, S; Ujita, M; Ariizumi, M; Ishii, C; Mizunuma, K; Fukuda, K


    The aim of this study was to determine the pathway of infrahyoid extension of the oropharyngeal abscess considering the anatomy of the fascial spaces by cross-sectional imaging. CT scans and MR images were retrospectively reviewed in ten patients with known infrahyoid extension of oropharyngeal abscesses (eight with acute tonsillitis, two with acute phlegmonous oropharyngitis). In seven of eight patients tonsillar abscesses descended along the deep cervical fascia converging on the hyoid bone and further accumulated in the anterior cervical space through which extension to the mediastinum took place in four patients. In seven patients the abscesses involved the retropharyngeal space at the infrahyoid neck. In two of these seven patients the abscesses directly extended down into the upper mediastinum through the retropharyngeal space. In one patients of the seven mediastinal spread of an abscess occurred through the posterior cervical space, not through the retropharyngeal space. Cross-sectional imaging is valuable in the evaluation of deep neck abscesses and the pathway of spread. The anterior cervical space in the infrahyoid neck is important for mediastinal extension of pharyngeal abscesses.

  2. Predicting Neck Abscess with Contrast-Enhanced Computed Tomography

    Melisa Lim Seer Yee


    Full Text Available Neck abscesses are difficult to diagnose and treat. Currently, contrast-enhanced computed tomography (CECT is the imaging modality of choice. The study aims to determine the predictive value of CECT findings in diagnosing neck abscess, causes of neck abscess and the most common neck space involved in the local population. 84 consecutive patients clinically suspected to have neck abscess who underwent CECT and surgical confirmation of pus were included. Demographic and clinical data were recorded. 75 patients were diagnosed as having neck abscess on CECT; out of those 71 patients were found to have pus. Overall CECT findings were found to have a high sensitivity (98.6% and positive predictive value (PPV (94.7% but lower specificity (67.2% in diagnosing neck abscess. The CECT diagnostic criterion with the highest PPV is the presence of rim irregularity (96%. The most common deep neck space involved is the submandibular compartment, which correlates with the finding that odontogenic cause was the most common identifiable cause of abscess in the study population. Thus, in a patient clinically suspected of having neck abscess, CECT findings of a hypodense mass with rim irregularity are helpful in confirming the diagnosis and guiding clinical management.

  3. Infection of a brain abscess of Mycoplasma hominis.

    Payan, D G; Seigal, N; Madoff, S


    Persistent fever in a young man after evacuation of a subdural hematoma caused by a depressed skull fracture made it necessary to carry out a computerized tomographic exam of the head that demonstrated a left frontal lobe brain abscess. Mycoplasma hominis was recovered from this abscess as the sole infecting organism. Serial computerized tomographic scans showed resolution after aspiration and antibiotic therapy.

  11. Gordonia terrae kidney graft abscess in a renal transplant patient.

    Nicodemo, A C; Odongo, F C A; Doi, A M; Sampaio, J L M


    We present the first report, to our knowledge, of a renal abscess cause by an infection from Gordonia terrae in a kidney transplant patient. The patient simultaneously had pulmonary tuberculosis and a perirenal allograft abscess caused by G. terrae. After treatment with imipenem, in addition to anti-tuberculous drugs, the patient was cured.

  14. Retroperitoneal abscess: an extra-abdominal manifestation

    Mallia, Alvin James; Ashwood, Neil; Arealis, George; Galanopoulos, Ilias


    Retroperitoneal abscesses are unusual occurrences with occult and insidious presentations. There is often a lack of abdominal signs, leading to delays in drainage and high mortality rates. We report a case of thigh emphysema in an 88-year-old patient with diabetes. Prior to admission the patient reported a vague 4-week history of left thigh pain and an inability to fully weight bear. She presented to our emergency department with sepsis and acute kidney impairment. An X-ray of her left femur ...

  15. 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.

    Berube, Bryan J; Murphy, Katherine; Torhan, Matthew C; Bowlin, Nicholas O; Williams, John D; Bowlin, Terry L; Moir, Donald T; Hauser, Alan R


    Pseudomonas aeruginosa is a leading cause of intra-abdominal infections, wound infections, and community-acquired folliculitis, each of which may involve macro- or micro-abscess formation. The rising incidence of multi-drug 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 murine abscess model of P. aeruginosa infection to test 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 abscesses, as neutrophil depletion resulted in increased abscess size, formation of dermonecrotic lesions on the skin, and dissemination of P. aeruginosa to internal organs. Consistent with the specificity of the T3SS/neutrophil interaction, P. aeruginosa lacking a functional T3SS was fully capable of causing abscesses in a neutropenic host. Phenoxyacetamide inhibitors attenuated abscess formation and aided in immune clearance of 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.

    Choi, Sang Hee; Lee, Kyoung Soo; Lee, Jin Seoung; Lee, Moon Gyu; Chung, Young Hwa; Lee, Young Sang; Lee, Sung Gyu; Auh, Yong Ho [Ulsan Univ. College of Medicine, Seoul (Korea, Republic of)


    The purpose of this study was to report the CT findings of four patients with hepatic abscess secondary to perforated acute cholecystitis. We retrospectively reviewed the CT findings of four patients with surgically proven hepatic abscess secondary to perforated acute cholecystitis. CT findings were analysed with respect to the observation of the gallbladder, pericholecystic space, hepatic lesions, and peritoneal cavity. All patients underwent cholecystectomy, with drainage of the hepatic abscess. CT findings of hepatic abscess secondary to perforated acute cholecystitis were hypodense mass formation in the pericholecystic space(n=3), irreguarity and wall defect of Gallbladder(n=4), thickened Gallbladder wall(n=4), stone with debris(n=4), and local or diffuse infiltration of the pericholecystic area(n=3), omentum, and mesentery. CT was helpful in diagnosing the hepatic abscess secondary to perforated acute cholecystitis.

  17. MRI Based Localisation and Quantification of Abscesses following Experimental S. aureus Intravenous Challenge: Application to Vaccine Evaluation.

    Elizabeth R Allen

    Full Text Available To develop and validate a sensitive and specific method of abscess enumeration and quantification in a preclinical model of Staphylococcus aureus infection.S. aureus infected murine kidneys were fixed in paraformaldehyde, impregnated with gadolinium, and embedded in agar blocks, which were subjected to 3D magnetic resonance microscopy on a 9.4T MRI scanner. Image analysis techniques were developed, which could identify and quantify abscesses. The result of this imaging was compared with histological examination. The impact of a S. aureus Sortase A vaccination regime was assessed using the technique.Up to 32 murine kidneys could be imaged in a single MRI run, yielding images with voxels of about 25 μm3. S. aureus abscesses could be readily identified in blinded analyses of the kidneys after 3 days of infection, with low inter-observer variability. Comparison with histological sections shows a striking correlation between the two techniques: all presumptive abscesses identified by MRI were confirmed histologically, and histology identified no abscesses not evident on MRI. In view of this, simulations were performed assuming that both MRI reconstruction, and histology examining all sections of the tissue, were fully sensitive and specific at abscess detection. This simulation showed that MRI provided more sensitive and precise estimates of abscess numbers and volume than histology, unless at least 5 histological sections are taken through the long axis of the kidney. We used the MRI technique described to investigate the impact of a S. aureus Sortase A vaccine.Post mortem MRI scanning of large batches of fixed organs has application in the preclinical assessment of S. aureus vaccines.

Tuberculous brain abscess usually occurs in an immunocompromised host. Almost all previously documented cases have involved acquired immune deficiency syndrome. We encountered a 53-year-old right-handed immunocompetent male who was initially suspected of having a cerebrovascular accident due to acute-onset right hemiparesis and paresthesia. A tentative diagnosis of brain tumor versus brain abscess was made on imaging studies. The patient was finally diagnosed with a tuberculous brain abscess based upon deterioration on imaging and a positive tuberculosis culture. The tuberculous brain abscess was located in the left parietal lobe, which resulted in Gerstmann's syndrome and right-sided apraxia. Stereotactic surgery was performed. He was also given antituberculosis chemotherapy and comprehensive rehabilitation. Considerable improvement was noted after rehabilitation. The patient even returned to a normal life and work. Our case demonstrates that an aggressive intensive inpatient rehabilitation program combined with stereotactic surgery and effective antituberculosis therapy play an important role in improving the outcome for patients with tuberculous brain abscess, Gerstmann's syndrome, and right-sided apraxia.Keywords: tuberculous brain abscess, Gerstmann's syndrome, rehabilitation

    Purpose: Single-voxel spectroscopy (SVS) has been the gold standard technique to diagnose the pyogenic abssess. Two-dimensional magnetic resonance spectroscopic imaging (MRSI) is able to provide spatial distribution of metabolic concentration, and is potentially more suitable for differential diagnosis between abscess and necrotic tumors. Therefore, the purpose of this study was to evaluate the equivalence of MRSI and SVS in the detection of the metabolites in pyogenic brain abscesses. Materials and methods: Forty-two patients with pyogenic abscesses were studied by using both SVS and MRSI methods. Two neuroradiologists reviewed the MRS data independently. A κ value was calculated to express inter-reader agreement of the abscesses metabolites, and a correlation coefficient was calculated to show the similarity of two spectra. After consensus judgment of two readers, the binary value of metabolites of pyogenic abscesses (presence or absence) was compared between SVS and MRSI. Results: The consistency of spectral interpretation of the two readers was very good (κ ranged from 0.95 to 1), and the similarity of two spectra was also very high (cc = 0.9 ± 0.05). After consensus judgment of two readers, the sensitivities of MRSI ranged from 91% (acetate) to 100% (amino acids, succinate, lactate, lipid), and the specificities of MRSI were 100% for detecting all metabolites with SVS as reference. Conclusion: SVS and MRSI provide similar metabolites in the cavity of pyogenic brain abscess. With additional metabolic information of cavity wall and contralateral normal-appearing brain tissue, MRSI would be a more suitable technique to differentiate abscesses from necrotic tumors.

  1. Evaluation and management of spinal epidural abscess.

    DeFroda, Steven F; DePasse, J Mason; Eltorai, Adam E M; Daniels, Alan H; Palumbo, Mark A


    Spinal epidural abscess (SEA) is an uncommon and potentially catastrophic condition. SEA often presents a diagnostic challenge, as the "classic triad" of fever, spinal pain, and neurological deficit is evident in only a minority of patients. When diagnosis is delayed, irreversible neurological damage may ensue. To minimize morbidity, an appropriate level of suspicion and an understanding of the diagnostic evaluation are essential. Infection should be suspected in patients presenting with axial pain, fever, or elevated inflammatory markers. Although patients with no known risk factors can develop SEA, clinical concern should be heightened in the presence of diabetes, intravenous drug use, chronic renal failure, immunosuppressant therapy, or a recent invasive spine procedure. When the clinical profile is consistent with the diagnosis of SEA, gadolinium-enhanced magnetic resonance imaging of the spinal column should be obtained on an emergent basis to delineate the location and neural compressive effect of the abscess. Rapid diagnosis allows for efficient treatment, which optimizes the potential for a positive outcome.

  2. Endoanal ultrasound in perianal fistulae and abscesses.

    Visscher, Arjan Paul; Felt-Bersma, Richelle J F


    Endoanal ultrasound is a technique that provides imaging of the anal sphincters and its surrounding structures as well as the pelvic floor. However, endoanal magnetic resonance imaging (MRI) is preferred by most physicians, although costs are higher and demand easily outgrows availability. Endoanal ultrasound is an accurate imaging modality delineating anatomy of both cryptoglandular as well as Crohn perianal fistula and abscess. Endoanal ultrasound is comparable with examination under anesthesia and equally sensitive as endoanal MRI in fistula detection. When fistula tracts or abscesses are located above the puborectal muscle, an additional endoanal MRI should be performed. Preoperative imaging is advocated in recurrent cryptoglandular fistula because a more complex pattern can be expected. Endoanal ultrasound can help avoid missing tracts during surgery, lowering the chance for the fistula to persist or recur. It can easily be performed in an outpatient setting and endosonographic skills are quickly incremented. Costs are low and endoanal ultrasound has the potential to improve outcome of patients with both cryptoglandular and fistulizing Crohn disease; therefore, it values more attention.

    In order to know the incidence and epidemiologic features of the Amebic Hepatic Abscess we realized this study in the medicine service. 86.67% were males, the average age was 41.38 +/- 18.60 years old being more frequent between 30 and 69 years old (74.48%). The more affected were farmers (60%), students (10%) and Housekeepers (6.67%). The average time of the disease was 12.12 +/- 6.35 dias. The most frequent symptoms were abdominal pain in the upper right quadrant (96.66%), Hepatomegaly (83.33%), Fever (82.22%), Diarrhea (37.77%), Nausea (36.66%), Jaundice (33.33%). The initial diagnosis was AHA (45.55%), acute cholecystitis (14.44%), generalized infectious syndrome (7.77%), acute hepatitis (6.66%). The most frequent studies was: echography (98.85%). AHA alone was in the right lobe (84.05%), left lobe (14.49%). The bigger abscess was of 12 cm in diameter. The treatment was metronidazole + antibioticos (37.78%), metronidazole + antibiotico+percutaneous drainage (24.45%), Metronidazole + surgical drainage (3.33%). The complications were right pleural effusion (8.89%), peritonitis (5.56%) and pioneumothorax (1.11%). The hospitalization time was 14 +/- 8.02 days. There was one death (1.11%). The AHA was ones of each 76 deliveries in our medicine service.

  4. Thigh abscess as an extension of psoas abscess: the first manifestation of perforated appendiceal adenocarcinoma: case report.

    Petrovic, Igor; Pecin, Ivan; Prutki, Maja; Augustin, Goran; Nedic, Ana; Gojevic, Ante; Potocki, Kristina; Reiner, Zeljko


    A 65-year-old woman presented with a painful, swollen, red right thigh and the mild pain in the right abdomen without nausea, vomiting or diarrhoea that lasted for 1 week. Laboratory findings revealed elevated inflammatory markers. Computed tomography of the right thigh, abdomen and pelvis showed an abscess formation in the adductor muscles draining from the abscess that completely occupied the right retroperitoneum up to the diaphragm, dissecting downward through the inguinal canal. Appendix was enlarged with an appendicolith. Emergent exploratory laparotomy revealed a perforated appendix with psoas abscess. Pathohistological diagnosis revealed adenocarcinoma of the appendix. Thigh abscess is an uncommon condition with insidious clinical presentation. Therefore, early recognition and setting of the correct diagnosis enables adequate treatment avoiding additional complications and in some cases potential life-threatening conditions. When upper leg abscess is suspected or proven abdominal examination is mandatory.

  5. Renal dysplasia with the ipsilateral ectopic ureter mimicking abscess of the prostate

    Grbić Dragan


    Full Text Available Introduction. In males the ectopic ureter usualy drains into the prostate (50%. During ureteric developement a thin membrane (Chawalla’s membrane separates the lumen of the ureter and the urogenital sinus at the point where the ureter joins the urogenital sinus. This membrane ruptures allowing urin to drain from the ureter to the urogenital sinus. The authors reported a case of renal dysplasia associated with ipsilateral uretral ectopia mimicking prostatic abscess. Case report. A subfebrile (37.3°C, 23-year-old patient, otherwise healthy, presented with persistent ascending perineal pain non-responsive to antibiotics and analgetics. Digitorectal examination (DRE showed asymmetric prostate with a soft, tender, buldging left lobe suggestive of prostatic abscess. The diagnosis was suspected using transrectal ultrasonography (TRUS, but the picture of the anechoic tubular structure in the left lobe of the prostate with a proximal undefined extraprostatic extension and a caudal intraprostatic blind end was incoclusive for the definitive diagnosis of prostatic abscess. Magnetic resonance imaging (MRI was ordered and definitive diagnosis of renal dysplasia associated with the ipsilateral ectopic ureter filled with inflamed content mimicking prostatic abscess was made. Transurethral incision/minimal resection of the distal, blindly closed end of left ectopic ureter was done. Endoscopic surgical treatment was sufficient for relief of clinical symptoms. The patient’s recovery was uneventful. Conclusion. To the best of our knowledge, a case of renal dysplasia with the ipsilateral ectopic ureter mimicking prostate abscess has not been reported so far. Cystic pelvic malformations in males may result from too craniall sprouting of the ureteral bud, with delayed absorption and ectopic opening of the distal end of the ureter.

    Aim: To determine CT features that can potentially differentiate right tubo-ovarian abscess (TOA) from acute appendicitis (AA; including abscess formation). Materials and methods: The abdominal computed tomography (CT) images of 48 patients with right-sided TOA (average age 39.3 {+-} 9.8 years) and 80 patients (average age 53.5 {+-} 19.9 years) with AA (24 with peri-appendicular abscess) were retrospectively evaluated. Two experienced radiologists evaluated 12 CT signs (including enlarged, thickened wall ovary, appendix diameter and wall thickness, peri-appendicular fluid collection, adjacent bowel wall thickening, fat stranding, free fluid, and extraluminal gas) in consensus to categorize the studies as either TOA or AA. The diagnosis and the frequency of each of the signs were correlated with the surgical and clinical outcome. Results: Reviewers classified 92% cases correctly (TOA = 85%, AA = 96.3%), 3% incorrectly (TOA = 6.3%, AA = 1.3%); 5% were equivocal (TOA = 8.3%, AA = 2.5%). In the peri-appendicular abscess group reviewers were correct in 100%. Frequent findings in the TOA group were an abnormal ovary (87.5%), peri-ovarian fat stranding (58.3%), and recto-sigmoid wall thickening (37.5%). An abnormal appendix was observed in 2% of TOA patients. Frequent findings in the AA group were a thickened wall (32.5%) and distended (80%) appendix. Recto-sigmoid wall thickening was less frequent in AA (12.5%). The appendix was not identified in 45.8% of the TOA patients compared to 15% AA. Conclusions: In the presence of a right lower quadrant inflammatory mass, peri-ovarian fat stranding, thickened recto-sigmoid wall, and a normal appearing caecum, in young patients favour the diagnosis of TOA. An unidentified appendix does not contribute to the differentiation between TOA and peri-appendicular abscess.

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

  8. Caffeine-Induced Premature Chromosome Condensation Results in the Apoptosis-Like Programmed Cell Death in Root Meristems of Vicia faba.

    Dorota Rybaczek

    Full Text Available We have demonstrated that the activation of apoptosis-like programmed cell death (AL-PCD was a secondary result of caffeine (CF induced premature chromosome condensation (PCC in hydroxyurea-synchronized Vicia faba root meristem cells. Initiation of the apoptotic-like cell degradation pathway seemed to be the result of DNA damage generated by treatment with hydroxyurea (HU [double-stranded breaks (DSBs mostly] and co-treatment with HU/CF [single-stranded breaks (SSBs mainly]. A single chromosome comet assay was successfully used to study different types of DNA damage (neutral variant-DSBs versus alkaline-DSBs or SSBs. The immunocytochemical detection of H2AXS139Ph and PARP-2 were used as markers for DSBs and SSBs, respectively. Acridine orange and ethidium bromide (AO/EB were applied for quantitative immunofluorescence measurements of dead, dying and living cells. Apoptotic-type DNA fragmentation and positive TUNEL reaction finally proved that CF triggers AL-PCD in stressed V. faba root meristem cells. In addition, the results obtained under transmission electron microscopy (TEM further revealed apoptotic-like features at the ultrastructural level of PCC-type cells: (i extensive vacuolization; (ii abnormal chromatin condensation, its marginalization and concomitant degradation; (iii formation of autophagy-like vesicles (iv protoplast shrinkage (v fragmentation of cell nuclei and (vi extensive degeneration of the cells. The results obtained have been discussed with respect to the vacuolar/autolytic type of plant-specific AL-PCD.

  10. Chronic and Recurrent Subareolar Abscess of the Breast from Underlying Causes

    An, Jin Kyung; Kang, Jae Hee; Kim, Eun Kyung; Hong, Young Ok [Eulji University, Eulji Hospital, Daejeon (Korea, Republic of)


    A subareolar abscess is the most common non-puerperal abscess of the breast. The main cause of a subareolar abscess is squamous metaplasia, which obstructs the lactiferous ducts and leads to the stasis of secretions and rupture of the ducts. However, there are other causes of subareolar abscess formation




    Full Text Available For many ENT-clinicians, it is very difficult to diagnose the stage of infection and options available for treating retropharyngeal space abscesses (RPSAs with very limited literature available to focus on the treatment options in limited resource setup. The main cutting edge of the study aims to correlate post-surgical complications of RPSAs and also to know the age related incidence. MATERIALS AND METHODS A prospective and retrospective study was undertaken in the Department of ENT, Narayana Medical College & General Hospital, Nellore, Andhra Pradesh during the period of 2011-15. The incumbent laboratory parameters like throat swab culture was done for all the suspected patients along with Complete blood counts (CBC & X-ray neck. RESULTS A total sixty suspected paediatric patients were prospectively and retrospectively studied for the period of four years, out of which males 35 and females were 25 respectively. The mean age of the patient was 8.96±1.25 years (IQR 4-14 years median age was 10 years. Radiological examination and Computed tomography (CT scan was done for greater accuracy. Blocked airway is most common postsurgical intervention and it was found to be statistically significant (p<0.00 with respect to lower age group of the population. CONCLUSION The present study concludes that proper positioning and avoidance of unnecessary manipulation is essential for preventing the postoperative complications of RPSAs. The spread of infection to the spine can lead to replicate the osteomyelitis and vertebral erosion, which in turn results in subluxation and subsequent spinal cord injury, rupture of the abscess with inhalation of contents can lead to aspiration pneumonia (or rarely asphyxiation and spread of infection to mediastinum can lead to mediastinitis. More research could be intervened to prevent the infections at poor resource setup.

  12. Spinal epidural abscess presenting as intra-abdominal pathology: a case report and literature review.

    Bremer, Andrew A; Darouiche, Rabih O


    Spinal epidural abscess is a rare infectious disease. However, if left unrecognized and untreated, the clinical outcome of spinal epidural abscess can be devastating. Correctly diagnosing a spinal epidural abscess in a timely fashion is often difficult, particularly if the clinician does not actively consider the diagnosis. The most common presenting symptoms of spinal epidural abscess include backache, radicular pain, weakness, and sensory deficits. However, early in its course, spinal epidural abscess can also present with vague and nondescript manifestations. In this report, we describe a case of spinal epidural abscess presenting as abdominal pain, and review the literature describing other cases of spinal epidural abscess presenting as intra-abdominal pathology.

  13. Ovarian tubercular abscess mimicking ovarian carcinoma: A rare case report

    Abinash Agarwala


    Full Text Available Although genito-urinary tuberculosis is common, reports of isolated ovarian tubercular abscess are rare. Ovarian tubercular abscess may mimics that of an ovarian tumor, leading to diagnostic difficulties. We reported a case report of 35 years woman presented with chronic pain abdomen, weight loss, low-grade fever and a right ovarian mass on ultrasound, with a significantly elevated CA-125 level. On clinical and radiological evidence, diagnosis of ovarian carcinoma was made, and laparotomy was performed with resection of the ovary. Postoperative specimen sent for histological examination that revealed classic epithelioid granuloma and acid-fast bacilli were present in Ziehl-Neelsen stain. Patient was put on antitubercular regimen from our Dots center. She is improving clinical after taking antitubercular drug and is on regular follow up at our chest outpatient department. Ovarian tubercular abscess is common in young women living in endemic zones, but case report of isolated tubercular abscess is rarely reported. CA-125 can be raised in both ovarian tubercular abscess and ovarian carcinoma, and only imaging is not always conclusive. Laparotomy followed by tissue diagnosis can be helpful in this situation. As the prognosis and treatment outcome of ovarian tubercular abscess and ovarian carcinoma is different, proper diagnosis by laparotomy should be done. Early diagnosis of ovarian tubercular abscess is vital as untreated disease can lead to infertility.

  16. Modeling root reinforcement using root-failure Weibull survival function

    M. Schwarz


    Full Text Available Root networks contribute to slope stability through complicated interactions that include mechanical compression and tension. Due to the spatial heterogeneity of root distribution and the dynamic of root turnover, the quantification of root reinforcement on steep slope is challenging and consequently the calculation of slope stability as well. Although the considerable advances in root reinforcement modeling, some important aspect remain neglected. In this study we address in particular to the role of root strength variability on the mechanical behaviors of a root bundle. Many factors may contribute to the variability of root mechanical properties even considering a single class of diameter. This work presents a new approach for quantifying root reinforcement that considers the variability of mechanical properties of each root diameter class. Using the data of laboratory tensile tests and field pullout tests, we calibrate the parameters of the Weibull survival function to implement the variability of root strength in a numerical model for the calculation of root reinforcement (RBMw. The results show that, for both laboratory and field datasets, the parameters of the Weibull distribution may be considered constant with the exponent equal to 2 and the normalized failure displacement equal to 1. Moreover, the results show that the variability of root strength in each root diameter class has a major influence on the behavior of a root bundle with important implications when considering different approaches in slope stability calculation. Sensitivity analysis shows that the calibration of the tensile force and the elasticity of the roots are the most important equations, as well as the root distribution. The new model allows the characterization of root reinforcement in terms of maximum pullout force, stiffness, and energy. Moreover, it simplifies the implementation of root reinforcement in slope stability models. The realistic quantification of root

  17. Sternoclavicular joint septic arthritis following paraspinal muscle abscess and septic lumbar spondylodiscitis with epidural abscess in a patient with diabetes: a case report

    Shioya Nobuki


    Full Text Available Abstract Background Septic arthritis of the sternoclavicular joint (SCJ is extremely rare, and usually appears to result from hematogenous spread. Predisposing factors include immunocompromising diseases such as diabetes. Case presentation A 61-year-old man with poorly controlled diabetes mellitus presented to our emergency department with low back pain, high fever, and a painful mass over his left SCJ. He had received two epidural blocks over the past 2 weeks for severe back and leg pain secondary to lumbar disc herniation. He did not complain of weakness or sensory changes of his lower limbs, and his bladder and bowel function were normal. He had no history of shoulder injection, subclavian vein catheterization, intravenous drug abuse, or focal infection including tooth decay. CT showed an abscess of the left SCJ, with extension into the mediastinum and sternocleidomastoid muscle, and left paraspinal muscle swelling at the level of L2. MRI showed spondylodiscitis of L3-L4 with a contiguous extradural abscess. Staphylococcus aureus was isolated from cultures of aspirated pus from his SCJ, and from his urine and blood. The SCJ abscess was incised and drained, and appropriate intravenous antibiotic therapy was administered. Two weeks after admission, the purulent discharge from the left SCJ had completely stopped, and the wound showed improvement. He was transferred to another ward for treatment of the ongoing back pain. Conclusion Diabetic patients with S. aureus bacteremia may be at risk of severe musculoskeletal infections via hematogenous spread.

    BACKGROUND: Etiologic organism is not frequently isolated despite multiple blood and lfuid cultures during management of pyogenic liver abscess (PLA). Such culture negative pyogen-ic liver abscess (CNPLA) is routinely managed by antibiotics targeted toKlebsiella pneumoniae. In this study, we evaluated the outcomes of such clinical practice. METHODS: All the patients with CNPLA andKlebsiella pneu-moniaePLA (KPPLA) admitted from January 2003 to Decem-ber 2011 were included in the study. A retrospective review of medical records was performed and demographic, clinical and outcome data were collected. RESULTS: A total of 528 patients were treated as CNPLA or KPPLA over the study period. CNPLA presented more com-monly with abdominal pain (P=0.024). KPPLA was more com-mon in older age (P=0.029) and was associated with thrombo-cytopenia (P=0.001), elevated creatinine (P=0.002), bilirubin (P=0.001), alanine aminotransferase (P=0.006) and C-reactive protein level (P=0.036). CNPLA patients tend to have anemia (P=0.015) and smaller abscess (P=0.008). There was no differ-ence in hospital stay (15.7 vs 16.8 days) or mortality (14.0% vs 11.0%). No patients required surgical drainage after initiation of medical therapy. CONCLUSION: Despite demographic and clinical differences between CNPLA and KPPLA, overall outcomes are not different.

    Full Text Available Consensus regarding management of pyogenic liver abscess (PLA among children is yet to emerge, and documentation on these subjects is scanty. Eighteen cases of PLA admitted at Children’s Medical Center in Tehran, Iran, over a 15 year period were analyzed to document the clinical profile and to evaluate the management of PLA among children. Records of all patients were reviewed for presenting signs and symptoms, any associated condition, investigative results, management, and follow–up findings. The overall rate of PLA was 48.9 per 100,000 pediatric admissions in our hospital. Moderate to severe malnutrition was present in five (27.8% and ascariasis in seven (38.9% children. Common presentations were fever (100%, abdominal pain (76.9%, and tender hepatomegaly (83.3%. Fourteen patients (77.8% had solitary liver abscess. Organism was isolated in 11 cases (63.3%, and staphylococcus aureus was the commonest isolate (66.7%.Twelve cases were managed conservatively with antibiotics alone, of these only two (16.7% required drainage later. Percutaneous aspiration was also undertaken in four additional (22.2% cases and open drainage in two (11.1%, at presentation. The overall mortality rate was 11.1%. Time taken for complete resolution ranged from 10 to 40 days. Altogether, we conclude that any child presenting with fever, abdominal pain, and tender hepatomegaly should be subjected to ultrasound scan for early detection of PLA. It seems that a combination of cloxacillin and gentamicin or a third generation cephalosporine and gentamicin, especially in infants, is a satistactory initial coverage. Therapeutic drainage is not an obligation in all cases of PLA. When required, percutaneous needle aspiration is safe and effective. Resolution and significant reduction in mortality has been made possible by early detection and appropriate antibiotic therapy.

  20. Injection site abscess due to mycobacterium fortuitum: A case report

    Devi DR


    Full Text Available Injection abscess is an iatrogenic infection occurring as an isolated case or as cluster outbreak. These infections occur due to contaminated injectables or lapse in sterilisation protocol. While pathogens such as Pseudomonas, Klebsiella, E. coli, and S. aureus are the usual causative agents, unusual organisms such as mycobacteria, particularly the rapidly growing non-tuberculous mycobacteria (NTM may cause the abscess. The chances of overlooking these organisms is high unless an acid fast bacilli (AFB smear and culture is done on all aspirated pus specimens. We report a case of a three year old child who presented with a gluteal abscess following an intramuscular infection with an unknown preparation.

  1. Escherichia coli Eyelid Abscess in a Patient with Alcoholic Cirrhosis

    Matthew Stratton


    Full Text Available Escherichia coli (E. coli is a rare cause of ocular infections and has not yet been reported as a cause of an ocular abscess. We describe the case of a 47-year-old woman with a history of alcoholic cirrhosis who presented with painful left lower eyelid swelling that did not improve with oral antibiotics. The abscess was drained and cultures were positive for E. coli. Patients with cirrhosis are at increased risk for developing E. coli bacterial infections, but to our knowledge this is the first case of an E. coli eyelid abscess reported in the literature.

  2. Tuberculous splenic abscess in a neonate with thrombocytopenia

    Amodio, John; Biskup, Darius; Rivera, Rafael; Fefferman, Nancy [New York University Medical Center, Department of Radiology, NY (United States); Shah, Shetal [New York University Medical Center, Division of Neonatology, Department of Pediatrics, Avenue, NY (United States)


    We present a case of a premature neonate who presented with anemia and persistent thrombocytopenia. The patient was ultimately diagnosed with disseminated tuberculosis. Initial sonographic evaluation of the abdomen revealed a heterogeneous but predominately hypoechoic spleen; there was subsequent evolution of a splenic abscess. The patient was treated medically with anti-tubercular drugs. Follow-up post-treatment sonograms of the spleen showed diminution of the abscess and the evolution of multiple calcifications compatible with calcified granulomas. This case is an unusual presentation of tuberculosis in an infant with splenic abscess associated with thrombocytopenia and anemia. (orig.)

  3. Rapidly Progressive Gas-containing Lumbar Spinal Epidural Abscess.

    Bang, Jin Hyuk; Cho, Keun-Tae


    Gas-containing (emphysematous) infections of the abdomen, pelvis, and extremities are well-known disease entities, which can potentially be life-threatening. They require aggressive medical and often surgical treatment. In the neurosurgical field, some cases of gas-containing brain abscess and subdural empyema have been reported. Sometimes they progress rapidly and even can cause fatal outcome. However, gas-containing spinal epidural abscess has been rarely reported and clinical course is unknown. We report on a case of rapidly progressive gas-containing lumbar spinal epidural abscess due to Enterococcus faecalis in a 72-year-old male patient with diabetes mellitus.

  4. Liver abscess associated with an oral flora bacterium Streptococcus anginosus

    Hava Yılmaz


    Full Text Available Viridans group Streptococcus, a bacterium of the oral flora has a low-virulence and rarely causes liver abscess. A 40-yearoldmale patient was admitted to the hospital complaining of high fever and malaise. A physical examination revealedpoor oral hygiene; there were caries on many teeth, and he had hepatomegaly. A hepatic abscess was identified inhis abdominal tomography. Streptococcus anginosus was isolated from the drainage material, and the bile ducts werenormal in his MRI cholangiography. An immunocompetent case of liver abscess caused by Streptococcus anginosusoriginated most probably from oral flora is presented here. J Microbiol Infect Dis 2012; 2(1:33-35

  5. Wandering biliary ascariasis with hepatic abscess in a postmenopausal woman.

    Nahar, N; Khan, N; Islam, S M; Chakraborty, R K; Rima, S Z; Alam, M N; Roy, A S


    Hepatobiliary ascariasis is common in developing countries where there is a low standard of public health and hygiene. We are reporting a rare case of ascariasis which induced multiple liver abscesses in a post menopausal woman who presented with fever, anorexia, nausea, vomiting and mild hepatomegaly. Ultrasonography revealed biliary ascariasis with multiple hepatic abscesses. Laparoscopic drainage of hepatic abscesses was done and microscopic examination of drainage materials showed decorticated eggs of Ascaris Lumbricoides. The post operative recovery of the patient was uneventful. Ultrasonography is a reliable modality to diagnose and follow up of such cases.

  6. Pancreatic abscess following scrub typhus associated with multiorgan failure

    Sun Young Yi; Jung Hyun Tae


    Clinical severity of scrub typhus ranges from mild to fatal. Acute pancreatitis with abscess formation is a rare complication among patients with scrub typhus. This paper reports a case of scrub typhus in a 75 years old man with acute pancreatitis with abscess formation and multiorgan failure. Abdominal computed tomography showed multiple infected pancreatic pseudocysts with peri-pancreatic infiltration. Multiorgan failure was successfully treated with doxycycline, ceftriaxone, and supportive management. The pancreatic abscess was successfully drained percutaneously and the sizes of pseudocysts decreased remarkably.

  7. Brain abscess caused by Citrobacter koseri infection in an adult.

    Liu, Heng-Wei; Chang, Chih-Ju; Hsieh, Cheng-Ta


    Citrobacter koseri is a gram-negative bacillus that causes mostly meningitis and brain abscesses in neonates and infants. However, brain abscess caused by Citrobacter koseri infection in an adult is extremely rare, and only 2 cases have been described. Here, we reported a 73-year-old male presenting with a 3-week headache. A history of diabetes mellitus was noted. The images revealed a brain abscess in the left frontal lobe and pus culture confirmed the growth of Citrobacter koseri. The clinical symptoms improved completely postoperatively.

  8. Residual amoebic liver abscess in a prospective renal transplant recipient

    Ashish V Choudhrie


    Full Text Available Amoebic liver abscess (ALA is by far the most common extraintestinal manifestation of invasive amoebiasis. The vast majority of these resolve with treatment; however, a small percentage of the treated ALAs are known to persist asymptomatically. Herein, we present a prospective renal allograft recipient with a residual liver abscess who had a successful renal transplant after treatment. In our opinion, persistence of a radiological finding of residual abscess in the absence of clinical disease does not appear to be a contraindication to renal transplantation.

  9. Renal abscess with Morganella morganii complicating leukemoid reaction.

    Osanai, Shinobu; Nakata, Hiroaki; Ishida, Kensuke; Hiramatsu, Mie; Toyoshima, Eri; Ogasa, Toshiyuki; Ohsaki, Yoshinobu; Kikuchi, Kenjiro


    We report a case of leukemoid reaction (LR) complicating renal abscess caused by Morganella morganii infection in an 80-year-old man. On administration, laboratory tests revealed white blood cell count of 76160 /microL and C reactive protein 3.09 mg/dL. Although chronic myeloid leukemia was suspected, bcr/abl fusion transcript was not observed. Contrast enhanced computer tomography imaging of the abdomen showed abscess in the right kidney. M. morganii was detected repeatedly in material of liquid from the abscess and arterial blood culture. To our knowledge, this is the first case of M. morganii infection complicating LR.

  10. Brodie's abscess of the ulna caused by Salmonella typhi.

    Ip, K C; Lam, Y L; Chang, Robert Y P


    Osteomyelitis caused by Salmonella typhi is rare in patients with no haemoglobinopathies or other diseases causing immunosuppression. Brodie's abscess is a special variety of subacute or chronic osteomyelitis. An otherwise healthy woman who presented with forearm swelling for 6 months was diagnosed with a Brodie's abscess of the ulna caused by Salmonella typhi. Magnetic resonance imaging and a computed tomography-guided needle biopsy were performed. She was later found to be a Salmonella carrier. The Brodie's abscess was treated by surgical debridement and a course of antibiotics. The clinical, radiological, and management aspects of the disease are discussed.

  11. Ascariasis as a cause of hepatic abscess: A report of 3 cases.

    Chauhan, V; Thakur, S; Rana, B


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

  12. Preseptal Cellulitis, Orbital Cellulitis, Orbital Abscess

    Rana Altan Yaycıoğlu


    Full Text Available Patients with orbital infections present to our clinic usually with unilateral pain, hyperemia, and edema of the eyelids. The differentiation between preseptal and orbital cellulitis is utmost important in that the second requires hospitalization. Since in orbital cellulitis, the tissues posterior to the orbital septum are involved, signs such as conjunctival chemosis, limited eye movement, decreased vision, as well as afferent pupil defect secondary to optic nerve involvement may also be observed. Prompt intravenous antibiotic treatment should be started, and surgical drainage may be performed if patient shows failure to improve in 48 hours despite optimal management. Without treatment, the clinical course may progress to subperiosteal or orbital abscess, and even to cavernous sinus thrombosis. (Turk J Ophthalmol 2012; 42: Supplement 52-6

  13. Spinal epidural abscess treated with antibiotics alone.

    Pathak, Ashish; Singh, Poonam; Gehlot, Prateek; Dhaneria, Mamta


    Spinal epidural abscess (SEA) is a rare clinical condition among children. Most patients do not present with classical signs. A 13-year-old boy without any predisposing factors presented with paraparesis, bladder and bowel involvement. MRI spine demonstrated an SEA at the C7 and D1 levels on both sides of the midline with cord oedema at the C2-3 to C6 level with minimal marrow oedema in the C6 vertebral body. We treated the patient with antibiotics (ceftriaxone and vancomycin) alone. The patient showed excellent response with only minimal residual gait disturbance at the end of 6 weeks of antibiotic therapy. This is the first paediatric report of complete recovery of a patient at clinical stage 4 following antibiotic treatment alone from India. However, caution should be exercised to closely monitor the patient's recovery as any progression in the neurological state warrants surgery.

  14. Splenic abscesses in a returning traveler.

    Guo, Richard F; Wong, Frances L; Perez, Mario L


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

  15. CT evaluation of primary epiphyseal bone abscesses

    Azouz, E.M. (Dept. of Radiology, McGill Univ., Montreal Children' s Hospital, PQ (Canada)); Greenspan, A. (Dept. of Radiology, California Univ., Davis School of Medicine, Sacramento, CA (United States)); Marton, D. (Dept. of Radiology, Montreal Univ., Hopital Ste Justine, PQ (Canada))


    We reviewed the clinical, radiographic, and computed tomographic (CT) findings in eight children with a histologically proven diagnosis of epiphyseal or apophyseal osteomyelitis. In all cases the femur was involved: in five the osteomyelitis was localized in the femoral condyle, in two it was in the greater trochanter, and in one it was in the femoral head epiphysis. In four of the six cases of epiphyseal involvement there was associated joint effusion or septic arthritis. CT examination may demonstrate a serpentine tract, a sequestrum, cortical destruction or adjacent soft tissue swelling and can differentiate osteomyelitis from other epiphyseal lucent lesions, particularly chondroblastoma and osteoid osteoma. Early diagnosis helps avoid delays in initiating antibiotic or surgical treatment caused by the unusual (epiphyseal or apophyseal) location of the bone abscess. (orig./GD)

  16. Otogenic cerebellar abscess due to purulent labyrinthitis and defect of the superior semicircular canal and its propagation through the endolymphatic sac.

    Durisin, Martin; Stöver, Timo; Leinung, Martin; Mangold, Andreas; Rittierodt, Marion; Lenarz, Thomas


    The otogenic cerebellar abscess still is one of the most dangerous complications of otitis media and implicates a high risk of mortality. Early diagnosis and therapy are decisive factors for the chances of rehabilitation. Radiologic imaging (CT/MRI) plays an important role. A broad-spectrum antibiotic according to antibiogram is indispensable. The type of surgical intervention depends on the cause and localization of the abscess. In this case the cerebellar abscess was a complication resulting from labyrinthitis, which was propagated through the endolymphatic duct and sac to the posterior fossa dura. Consequently, it could be cured ultimately only after petrosectomy and abscess drainage toward the mastoid cavity. It is mandatory to completely sanitize the infection surgically in order to avoid lethal complication especially in case of a delayed clinical course or recurrent symptoms of labyrinth involvement. Close interdisciplinary collaboration between ORL, neurosurgery and neuroradiology is desirable for successful therapy.

  17. Child case of spinal epidural abscess with successful conservative treatment following early diagnosis by CT and /sup 67/Ga SPECT

    Kusunoki, T.; Tsuda, H.; Sumimoto, S.; Kasajima, Y.; Ojima, S.; Honda, M.; Kanao, K.; Hamamoto, T.


    Although early diagnosis and treatment of spinal epidural abscess are emphasized in children in view of its prognosis, these are very difficult because of the nonspecific symptoms of the disease. A 6-year-old boy complained of lumbar pain and difficulty in walking. Computed tomography, performed 6 days after the occurrence of complaints, revealed space occupying lesion in the spinal canal and epidural space at the level of L2-S1. Subsequent single photon emission computed tomography (SPECT) with Ga-67 clearly visualized active inflammation resulting from epidural abscess. The patient received intensive chemotherapy alone. Twenty-one days later, Ga-67 uptake disappeared on SPECT images. The finding indicates the usefulness of diagnostic imagings in the early diagnosis and treatment of spinal epidural abscess, thus avoiding surgery, the role of which has been under debate.

  18. Management of Pediatric Skin Abscesses in Pediatric, General Academic and Community Emergency Departments

    Baumann, Brigitte M


    Full Text Available Objectives: To compare the evaluation and management of pediatric cutaneous abscess patients at three different emergency department (ED settings.Method: We conducted a retrospective cohort study at two academic pediatric hospital EDs, a general academic ED and a community ED in 2007, with random sampling of 100 patients at the three academic EDs and inclusion of 92 patients from the community ED. Eligible patients were ≤18 years who had a cutaneous abscess. We recorded demographics, predisposing conditions, physical exam findings, incision and drainage procedures, therapeutics and final disposition. Laboratory data were reviewed for culture results and antimicrobial sensitivities. For subjects managed as outpatients from the ED, we determined where patients were instructed to follow up and, using electronic medical records, ascertained the proportion of patients who returned to the ED for further management.Result: Of 392 subjects, 59% were female and the median age was 7.7 years. Children at academic sites had larger abscesses compared to community patients, (3.5 versus 2.5 cm, p=0.02. Abscess incision and drainage occurred in 225 (57% children, with the lowest rate at the academic pediatric hospital EDs (51% despite the relatively larger abscess size. Procedural sedation and the collection of wound cultures were more frequent at the academic pediatric hospital and the general academic EDs. Methicillin-resistant Staphylococcus aureus (MRSA prevalence did not differ among sites; however, practitioners at the academic pediatric hospital EDs (92% and the general academic ED (86% were more likely to initiate empiric MRSA antibiotic therapy than the community site (71%, (p<0.0001. At discharge, children who received care at the community ED were more likely to be given a prescription for a narcotic (23% and told to return to the ED for ongoing wound care (65%. Of all sites, the community ED also had the highest percentage of follow-up visits (37

  19. Hemolysin activities as virulence factor of Enterococcus faecalis isolated from saliva and periapical abscess (gene detection by PCR

    Dewa Ayu N.P.A


    Full Text Available Background: Enterococcus faecalis is a normal flora of the oral cavity, commonly detected in saliva and persistence in endodontic infections. These bacteria have diverse survival and virulence factors. Hemolysin is one of the factor and still had unclear role as a virulence factor of the Enterococcus faecalis to survive in the root canal. Purpose: The purpose of this research was to analyze the presence and activity of hemolysin gene and its activity as a virulence factor isolated from saliva and root canals with periapical abscess. Yet by understanding one of the phenotypes characters which is hemolysin, it is expected a successful endodontic treatment can be provided with the persistent of Enterococcus faecalis bacteria. Methods: Method of the research starting with the identification of Enterococcus faecalis bacteria in isolated saliva and periapical abscess was done in the first part of the study. Then the phenotypes character of Enterococcus faecalis such as gene detection and expression of hemolysin in blood agar cultures of the 60 colonies samples were performed in the later part. Results: Not all of the colonies cultured were identified as Enterococcus faecalis. All positive detection on hemolysin gene showed hemolysin expresion in both isolated samples. However, there were samples with hemolysin expression eventough no hemolysin gene detected. Hemolysin expression detection in saliva was higher due to different activation phase of hemolysin in saliva. The study with just one primer could lead to the possibility of undetected hemolysin gene, eventough there were samples that did not have hemolysin gene. The proportion of hemolysin expression in root canals were less than saliva, this could be influenced by environmental factors. However, Hemolysin was considered as important virulence factor, particularly for disease therapy. Conclusion: The conclusion of this research was hemolysin gene discovered in clinical isolated saliva and root

  20. Masticator space abscess in a 47-day-old infant

    Eunhee Kim


    Full Text Available A 47-day-old male infant presented with fever, poor oral intake, irritability, and right-sided bluish buccal swelling. Contrast-enhanced computed tomography of the neck showed a round mass lesion of about 2.0¡¿1.5 cm that suggested abscess formation in the right masticator space. Ultrasound-guided extraoral aspiration of the abscess at the right masseter muscle was successful. Staphylococcus aureus was identified in the culture from the aspirated pus and blood. Appropriate antibiotics were given and the patient recovered. The patient underwent follow-up ultrasonography that showed an improved state of the previously observed right masseter muscle swelling at about 1 month after hospital discharge. A masticator space abscess usually originates from an odontogenic infection in adults. We report a case of masticator space abscess in a 47-day-old infant in whom septicemia without odontogenic infection was suspected.

  1. [Breast abscess with Salmonella typhi and review of the literature].

    Delori, M; Abgueguen, P; Chennebault, J-M; Pichard, E; Fanello, S


    We report the case of a 54-year-old woman who presented with breast abscess, which appeared through a common alimentary toxi-infection with Salmonella Typhi, infection, which implied twelve patients having attended the same restaurant. With around hundred native cases a year in France, typhoid fever is not a very frequent toxi-infection. Among the known extra-intestinal manifestations of Salmonella infections, the breast abscess remains rare and the literature revealed less than ten published cases, including some revealed the disease. In our observation, the imputability of S. Typhi was retained based on the chronology of the clinical signs, specific treatments, and the successful outcome under antibiotherapy, in spite of the negativity of the breast abscess bacteriological samples. We also analyze rare cases of breast abscess due to S. Typhi found in the literature.

    Dursun Ozgur Karakas


    Full Text Available Coexistence of a diverticular abscess and colorectal cancer is an extremely rare phenomenon. The clinical presentation and the extension of a diverticular abscess could cause mis-staging of colon cancer. We are presenting an overstaged colon cancer due to a diverticular abscess penetrating into the abdominal wall. A 65-year-old male patient with a history of an enlarging mass in the left lower quadrant of the abdomen was admitted to our service. Diagnostic studies revealed a sigmoid tumor communicating with an abdominal wall mass. The patient was clinically staged as T4 N1. Exploration revealed a diverticular abscess penetrating into the abdominal wall and a sigmoid tumor. Histopathological examination reported an intermediately differentiated T3 N0 adenocarcinoma of the sigmoid colon. After an uneventful postoperative recovery, the patient was referred to chemotherapy. [Arch Clin Exp Surg 2015; 4(4.000: 231-233

  4. An Unusual Cause of Renal and Perirenal Abscesses: Candida albicans



    Full Text Available A 42-year-old female with history of surgery due to urolithiasis was admitted to hospital with complaints of fever, left fl ank pain and vomiting. She was found to have acute kidney injury due to urinary tract infection. Abdominal computed tomography revealed right atrophic kidney and left renal and perirenal abscesses together with urolithiasis. Urine, blood and abscess cultures yielded C. albicans. The patient was treated with fl uconazole and percutaneous drainage of the perirenal abscess, which was 60 mm in diameter. Her serum creatinine returned to the normal ranges within two weeks of hospitalization. Nearly 18 months following this presentation, she has normal serum creatinine and no abscesses in the kidneys.

  6. Disseminated Cunninghamella bertholletiae infection with spinal epidural abscess in a kidney transplant patient: case report and literature review.

    Navanukroh, O; Jitmuang, A; Chayakulkeeree, M; Ngamskulrungroj, P


    Cunninghamella bertholletiae is a rare cause of invasive mucormycosis. We report the case of a 42-year-old Thai woman who suffered from disseminated C. bertholletiae infection. The patient developed dry cough, sharp shooting pain in the left buttock referred to the left leg, and fever 1 month after undergoing deceased-donor kidney transplantation. Radiographic studies exhibited multiple pulmonary cavities, osteomyelitis of the sacral spine, epidural abscess along the lumbrosacral spine, and paravertebral soft tissue involvement. Surgical debridement of the epidural abscess concurrent with prolonged intravenous administration of amphotericin B resulted in a good outcome.

    Kim-Diêp Dang-Tran


    Full Text Available Cardiac abscess is an uncommon and fatal complication after transplantation. We report a case of an initially isolated aspergillosis myocardial abscess diagnosed by cardiac magnetic resonance imaging (CMRI. At that time, there was no other biological evidence or other extracardiac manifestations. A three-month course of dual antifungal therapy followed by a single antifungal therapy was empirically given. Six month after admission, Aspergillus fumigatus was isolated for the first time and the patient deceased from a disseminated aspergillosis.

  8. Cervical abscess and pharyngeal fistula in a horse.

    Scott, E A


    A weanling Quarter Horse filly developed ventral swelling of the lower cervical area after difficult passage of a stomach tube for deworming. Intermittent bilateral nasal discharge developed. Radiography revealed fluid and gas density dorsal to the trachea and esophagus. Surgical incision with drainage and debridement of the abscess and fistulous tract, facilitated by use of drains, led to complete recovery. Contrast medium injected after surgery demonstrated a communication between the abscess and the pharyngeal region.

  9. Diabetes mellitus and spinal epidural abscess: clinical or surgical treatment?

    Felício, João S; Martins, Carlliane Lins P; Liberman, Bernardo


    Spinal epidural abscess (SEA) is an uncommon condition and its most important predisposing factor is diabetes mellitus. Although the treatment of choice is prompt surgical abscess evacuation, followed by antibiotic therapy, successful conservative treatment of SEA has been reported in some cases. We describe a SEA case in a 23-year old white woman with diabetes for 14 years, who was successfully treated only with antibiotics, and achieved full recovery at the fourth month of follow-up.

    Rakotonaivo, A; Ranoharison, H D; Razarimahefa, S H; Rakotozafindrabe, R; Rabenjanahary, T H; Ramanampamonjy, R M


    Acute cholangitis secondary to ascariasis is rare and occurs mainly in areas of high endemicity. The clinical presentation is non-specific, sometimes complicated by liver abscess. Abdominal ultrasound plays an important role in diagnosis and therapeutic surveillance. We report the case of a 35-year-old Malagasy woman with an acute cholangitis secondary to ascariasis and complicated by liver abscesses and its course to full recovery under medical treatment.

  11. A case of retropharyngeal abscess with spondylitis causing tetraplegia

    Takeshi Kusunoki


    Full Text Available We report a case of retropharyngeal abscess with spondylitis causing tetraplegia. At a previous hospital, administration of antibiotics improved the inflammation findings. However, magnetic resonace imaging showed a remaining retropharyngeal abscess. This patient showed a disturbance of consciousness under this therapy. Therefore, he was admitted to our hospital and underwent a drainage operation. At 1 day after this operation, he recovered from the disturbance of consciousness.

  12. Epiglottitis with an abscess caused by Haemophilus parainfluenzae

    Juul, Marie Louise; Johansen, Helle Krogh; Homøe, Preben


    A healthy 23-year-old man was admitted under the diagnosis of acute epiglottitis. Flexible fiber laryngoscopic examination showed a swollen epiglottis with an abscess. Microbiologic swab showed Haemophilus parainfluenzae, non-haemolytic Streptococcus and non-haemolytic Streptococcus salivarius....... Only in 1984 a case of acute epiglottitis due to H. parainfluenzae has been described in the literature. Still, in this case we think that H. parainfluenzae was the most likely pathogen causing the abscess....

  13. Cervical Epidural and Retropharyngeal Abscess Induced by a Chicken Bone

    Wei-Ting Hsu


    Full Text Available Retropharyngeal abscess is occasionally seen in children, but is less common in adults where it usually occurs secondary to iatrogenic oropharynx trauma or a perforated foreign body in the oropharynx. Spinal epidural abscess in combination with a retropharyngeal abscess, which may cause rapid and irreversible neurological deterioration, is not often found, as indicated by the very few reports in the literature. Here we report a 52-year-old male with a clinical history of seizure and mental retardation since childhood who presented at our emergency room with severe sore throat of 1 day’s duration. A chicken bone was removed successfully. However, he complained of progressive dysphagia, sore throat and posterior neck pain during the following 5 days. Flexible fiber-laryngoscopy showed bulging of the retropharyngeal wall and a small ulcer at the right posterior pharyngeal wall. A neck computed tomography (CT scan showed a retropharyngeal abscess at the oropharynx and hypopharynx level. His symptoms showed partial improvement after the administration of intravenous antibiotics. However, 2 weeks later he developed high fever, posterior neck pain and flaccid tetra-paresia. Emergent neck CT scan revealed a mild retropharyngeal abscess and epidural abscess formation between the second and third cervical vertebrae. The patient’s family refused drainage of the pre-vertebral and epidural pus. After receiving 2 months of antibiotics, the patient regained the mobility of his limbs

  14. Microbiology and management of peritonsillar, retropharyngeal, and parapharyngeal abscesses.

    Brook, Itzhak


    This review describes the microbiology, diagnosis, and management of peritonsillar, retropharyngeal, and parapharyngeal abscesses in children. Predominant anaerobic organisms isolated in peritonsillar, lateral pharyngeal, and retropharyngeal abscesses are Prevotella, Porphyromonas, Fusobacterium and Peptostreptococcus spp.; aerobic organisms are group A streptococcus ( Streptococcus pyogenes ), Staphylococcus aureus and Haemophilus influenzae . Anaerobic bacteria can be isolated from most abscesses whenever appropriate techniques for their cultivation have been used, while S. pyogenes is isolated in only about one third of cases. More than two thirds of deep neck abscesses contain beta-lactamase producing organisms. Management of tonsillar, peritonsillar, and retropharyngeal abscesses is similar. Systemic antimicrobial therapy should be given in large doses whenever the diagnosis is made. However, when pus is formed, antimicrobial therapy is effective only in conjunction with adequate surgical drainage. Untreated abscesses can rupture spontaneously into the pharynx, causing catastrophic aspiration. Other complications are extension of infection laterally to the side of the neck or dissection into the posterior mediastinum through facial planes and the prevertebral space. Death can occur from aspiration, airway obstruction, erosion into major blood vessels, or extension to the mediastinum.

  15. Brain Abscesses Associated with Asymptomatic Pulmonary Arteriovenous Fistulas

    Nam, Taek-Kyun; Park, Yong-sook; Kwon, Jeong-taik


    Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe. We performed a craniotomy and abscess removal. Bacteriological culture proved negative. Her chest computed tomography (CT) showed multiple AVFs. Therapeutic embolization of multiple pulmonary AVFs was performed and antibiotics were administered for 8 weeks. A 45-year-old woman presented with a 7-day history of progressive left hemiparesis. She had no remarkable past medical history or family history. On admission, blood examination showed a white blood cell count of 6290 cells/uL and a high sensitive C-reactive protein of 2.62 mg/L. CT and MR imaging with MR spectroscopy revealed an enhancing lesion involving the right motor and sensory cortex with marked perilesional edema that suggested a brain abscess. A chest CT revealed a pulmonary AVF in the right upper lung. The pulmonary AVF was obliterated with embolization. There needs to consider pulmonary AVF as an etiology of cerebral abscess when routine investigations fail to detect a source. PMID:28061502

  16. Brain abscess associated with ethmoidal sinus osteoma: A case report

    Hiroaki Nagashima


    Full Text Available Osteoma of the paranasal sinus is uncommon, and the occurrence of brain abscess associated with ethmoidal osteoma is particularly rare. We report here a case of a brain abscess complicating an ethmoidal osteoma in a 68-year-old man who presented with high-grade fever and disturbance in the level of consciousness. Computed tomography scanning and magnetic resonance imaging revealed a ring-enhancing mass in the left frontal lobe with surrounding edema and a bony mass in the ethmoidal sinus. We scheduled a two-stage operation. First, emergency aspiration and drainage of the abscess via the forehead were performed to reduce the abscess volume. These were followed by a left frontal craniotomy to totally remove both the brain abscess and the bony mass. The bony mass had breached the dura mater. After removing the bony mass, we repaired the anterior skull base using a pericranial flap. Pathological findings of the bony tumor were consistent with osteoma. The postoperative course was uneventful. In the case of a huge brain abscess associated with an ethmoidal osteoma, volume reduction by drainage followed by surgical removal of both lesions may help to control infection and achieve a cure. Use of a vascularized pericranial flap is important to prevent direct communication between the paranasal sinuses and the cranial cavity.

  17. A Case of an Abdominal Wall Abscess Associated with Spilled Gallstones: Imaging Findings and Clinical Significance

    Son, Youn Mi; Kim, Hyuk Jung; Bak, Cheol Hee [Seoul Medical Center, Seoul (Korea, Republic of)


    Laparoscopic cholecystectomy (LC) has been the gold standard for symptomatic gall stones for the last 20 years. The spillage of stones is reported in up to one-third of all LCs but clinical squeals caused by dropped gallstones are uncommon. We recently observed a patient with late abdominal wall abscess formation as a result of dropped gall stones after LC, who in the end, underwent open surgery because the medical therapy including antibiotics and percutaneous catheter drainage was not fully effective

  18. Anorectal abscess and fistula-in-ano: evidence-based management.

    Rizzo, Julie A; Naig, Anna L; Johnson, Eric K


    The management of anorectal abscess and anal fistula has changed markedly with time. Invasive methods with high resulting rates of incontinence have given way to sphincter-sparing methods that have a much lower associated morbidity. There has been an increase in reports in the medical literature describing the success rates of the varying methods of dealing with this condition. This article reviews the various methods of treatment and evidence supporting their use and explores advances that may lead to new therapies.

  19. Spinal Subdural Abscess Following Laminectomy for Symptomatic Stenosis: A Report of 2 Cases and Review of the Literature

    Ramos, Alexander D.; Rolston, John D.; Gauger, Grant E.; Larson, Paul S.


    Case series Patient: Male, 87 • Male, 62 Final Diagnosis: Spinal subdural abscess Symptoms: Fever • pain • weakness Medication: — Clinical Procedure: Laminectomy • durotomy • drainage • debridement Specialty: Neurosurgery Objective: Rare disease Background: Spinal subdural abscesses, also known as empyemas, are rare infectious lesions, the exact incidence of which is unknown. Presentation is typically dramatic, with back pain, fever, motor, and sensory deficits. Rapid identification and surgical intervention with laminectomy, durotomy, and washout provides the best outcomes. While hematogenous spread of an extra-spinal infection is the most common cause of this condition, a significant number of cases result from iatrogenic mechanisms, including lumbar punctures, epidural injections, and surgery. Case Report: Here we present 2 cases: 1) an 87-year-old man with type 2 diabetes, schizophrenia, mild cognitive impairment, and symptomatic lumbar spinal stenosis and 2) a 62-year-old man with a prior L3–4 spinal fusion with symptomatic lumbar spinal stenosis. In both cases, patients underwent laminectomy for spinal stenosis and developed epidural abscess. Following successful drainage of the epidural abscess, they continued to be symptomatic, and repeat imaging revealed the presence of a subdural abscess that was subsequently evacuated. Case 1 had significant improvement with residual lower-extremity weakness, while Case 2 made a complete neurological recovery. Conclusions: These cases illustrate patients at increased risk for developing this rare spinal infection, and demonstrate that rapid recognition and surgical treatment is key to cure and recovery. Review of the literature highlights pertinent risk factors and demonstrates nearly one-third of reported cases have an iatrogenic etiology. The cases presented here demonstrate that a subdural process should be suspected in any patient with intractable pain following treatment of an epidural abscess. PMID

  20. Perturbation of auxin homeostasis by overexpression of wild-type IAA15 results in impaired stem cell differentiation and gravitropism in roots.

    Da-Wei Yan

    Full Text Available Aux/IAAs interact with auxin response factors (ARFs to repress their transcriptional activity in the auxin signaling pathway. Previous studies have focused on gain-of-function mutations of domain II and little is known about whether the expression level of wild-type Aux/IAAs can modulate auxin homeostasis. Here we examined the perturbation of auxin homeostasis by ectopic expression of wild-type IAA15. Root gravitropism and stem cell differentiation were also analyzed. The transgenic lines were less sensitive to exogenous auxin and exhibited low-auxin phenotypes including failures in gravity response and defects in stem cell differentiation. Overexpression lines also showed an increase in auxin concentration and reduced polar auxin transport. These results demonstrate that an alteration in the expression of wild-type IAA15 can disrupt auxin homeostasis.

  1. Effect of reduced z-axis scan coverage on diagnostic performance and radiation dose of neck computed tomography in patients with suspected cervical abscess.

    Weiss, Jakob; Maurer, Michael; Ketelsen, Dominik; Notohamiprodjo, Mike; Zinsser, Dominik; Wichmann, Julian L; Nikolaou, Konstantin; Bamberg, Fabian; Othman, Ahmed E


    To evaluate the effect of reduced z-axis scan coverage on diagnostic performance and radiation dose of neck CT in patients with suspected cervical abscess. Fifty-one patients with suspected cervical abscess were included and underwent contrast-enhanced neck CT on a 2nd or 3rd generation dual-source CT system. Image acquisition ranged from the aortic arch to the upper roof of the frontal sinuses (CTstd). Subsequently, series with reduced z-axis coverage (CTred) were reconstructed starting at the aortic arch up to the orbital floor. CTstd and CTred were independently assessed by two radiologists for the presence/absence of cervical abscesses and for incidental and alternative findings. In addition, diagnostic accuracy for the depiction of the cervical abscesses was calculated for both readers. Furthermore, DLP (dose-length-product), effective dose (ED) and organ doses were calculated and compared for CTred and CTstd, using a commercially available dose management platform. A total of 41 abscesses and 3 incidental/alternative findings were identified in CTstd. All abscesses and incidental/alternative findings could also be detected on CTred resulting in a sensitivity and specificity of 1.0 for both readers. DLP, ED and organ doses of the brain, the eye lenses, the red bone marrow and the salivary glands of CTred were significantly lower than for CTstd (pz-axis coverage of neck CT allows for a significant reduction of effective dose and organ doses at similar diagnostic performance as compared to CTstd.

  2. Diagnosis of amebic liver abscess and amebic colitis by detection of Entamoeba histolytica DNA in blood, urine, and saliva by a real-time PCR assay.

    Haque, Rashidul; Kabir, Mamun; Noor, Zannatun; Rahman, S M Mazidur; Mondal, Dinesh; Alam, Faisal; Rahman, Intekhab; Al Mahmood, Abdullh; Ahmed, Nooruddin; Petri, William A


    The noninvasive diagnosis of amebic liver abscess is challenging, as most patients at the time of diagnosis do not have a concurrent intestinal infection with Entamoeba histolytica. Fecal testing for E. histolytica parasite antigen or DNA is negative in most patients. A real-time PCR assay was evaluated for detection of E. histolytica DNA in blood, urine, and saliva samples from amebic liver abscess as well as amebic colitis patients in Bangladesh. A total of 98 amebic liver abscess and 28 amebic colitis patients and 43 control subjects were examined. The real-time PCR assay detected E. histolytica DNA in 49%, 77%, and 69% of blood, urine, and saliva specimens from the amebic liver abscess patients. For amebic colitis the sensitivity of the real-time PCR assay for detection of E. histolytica DNA in blood, urine, and saliva was 36%, 61%, and 64%, respectively. All blood, urine, and saliva samples from control subjects were negative by the real-time PCR assay for E. histolytica DNA. When the real-time PCR assay results of the urine and saliva specimens were taken together (positive either in urine or saliva), the real-time PCR assay was 97% and 89% sensitive for detection of E. histolytica DNA in liver abscess and intestinal infection, respectively. We conclude that the detection of E. histolytica DNA in saliva and urine could be used as a diagnostic tool for amebic liver abscess.

  3. Use of partial prostatectomy for treatment of prostatic abscesses and cysts in dogs.

    Rawlings, C A; Mahaffey, M B; Barsanti, J A; Quandt, J E; Oliver, J E; Crowell, W A; Downs, M O; Stampley, A R; Allen, S W


    To determine whether dogs had prostatic disease, urinary incontinence, or urinary tract infection 1 year after partial prostatectomy to treat prostatic abscesses and cysts. Prospective study. 20 male dogs with prostatic abscesses or cysts. Fifteen dogs had evidence of urinary tract infection. Only 8 dogs urinated normally; the remainder dribbled, had obstructions, or required medical treatment. Partial prostatectomy was performed on each dog. Sexually intact dogs (n = 12) also were castrated. None of the dogs had return of prostatic cystic enlargement or clinical signs of prostatic disease during the first year after surgery. Two dogs were euthanatized within 1 year after surgery, with 1 dog having prostatic enlargement and adenocarcinoma and 1 dog having unrelated lymphosarcoma. Fifteen dogs were continent. The remaining 5 dogs urinated normally but had intermittent and minor incontinence. Eleven dogs had no signs of infection 1 year after surgery, 5 had pyuria or positive urine bacteriologic culture results, 2 did not have urinalysis performed, and 2 were euthanatized. Dogs with severe prostatic abscesses or cysts and infections can be successfully treated by partial prostatectomy with an ultrasonic surgical aspirator and castration, resulting in long-term disease resolution. Although most dogs with severe prostatic disease do not urinate normally before surgery, nearly all dogs resume normal micturition after partial prostatectomy. Postoperative results of partial prostatectomy appear to be better than those of previous drainage techniques for treatment of prostatic cavitary disease.

  4. Churg-Strauss syndrome complicated by colon erosion,acalculous cholecystitis and liver abscesses

    Msahiro Suzuki; Kazuo Nabeshima; Mitsukazu Miyazaki; Hitoshi Yoshimura; Shinsei Tagawa; Katsuya Shiraki


    We report on a case of Churg-Strauss syndrome (CSS)with colon erosion, cholecystitis and liver abscesses. A 21-year-old woman with a history of bronchial asthma for 3 years was admitted with a complaint of abdominal pain. Laboratory findings included remarkable leukocytosis and eosinophilia, and a colonoscopy revealed erosion from the rectum to the ileocecal region. In addition, a colonic biopsy specimen showed necrotizing vasculitis and marked eosinophilic infiltration. On the basis of the clinical features and histopathological findings, she was diagnosed with CSS and subsequently treated with oral prednisolone,after which the eosinophilia and abdominal pain disappeared. However, on the 15th d in hospital she developed cholecystitis and liver abscesses. She was therefore treated with antibiotics and as a result went into clinical remission.

  5. Extensive Frontoparietal Abscess: Complication of Frontal Sinusitis (Pott’s Puffy Tumor

    Raquel Andrade Lauria


    Full Text Available First described in 1768, the Pott’s puffy tumor is a subperiosteal abscess associated with frontal bone osteomyelitis, resulting from trauma or frontal sinusitis. The classic clinical presentation consists of purulent rhinorrhea, fever, headache, and frontal swelling. The diagnosis is confirmed by CT scan and treatment requires intravenous antibiotics, analgesia, and surgical intervention. Early diagnosis and aggressive medical and surgical approach are essential for a good outcome. It rare and the early diagnosis is important; we describe the case of a 14-year-old adolescent with Pott’s puffy tumor who was initially treated inadequately, evolving with extensive frontoparietal abscess. The patient underwent surgical treatment with endoscopic endonasal and external approaches combined. Intravenous antibiotics were prescribed for a prolonged time, with good outcome and remission of the complaints.

  6. A case of deep cervical and mediastinal abscess induced by radiotherapy

    Hori, Yohji [Tokushima Univ. (Japan). School of Medicine; Kashima, Kenji [Tokushima Red Cross Hospital, Komatsushima (Japan); Satoh, Go [Shikoku Central Hospital, Kawanoe, Ehime (Japan); Kanamura, Akira [Nate ENT Clinic, Tokushima (Japan)


    A 51-year-old man was hospitalized to receive radiotherapy for mesopharyngeal carcinoma. After he was treated at a dose of 24 Gy, redness of the neck and high fever appeared, but total white blood cell (WBC) count remained within the normal level. After four days, C reactive protein (CRP) was elevated, and then CT scan demonstrated cervical and mediastinal abscess. In addition to antibiotic therapy, emergency cervical drainage and frequent evaculation of necrotic tissue were effective, resulting in complete recovery from deep cervical and mediastinal abscess. The reason that total WBC count was not elevated in the early stage of his neck infection was probably bone marrow suppression induced by radiotherapy. Therefore, CRP is a more suitable index than total WBC count for early diagnosis of cervical infection of the patient with radiotherapy. (author)

  7. Bacteria Associated with Subcutaneous Abscesses of Cattle Caused by Hypoderma spp Larvae in North of Iran

    Hossein Tajik


    Full Text Available This study was performed from February to April 2006; several visits were made to abattoirs in the north of Iran for Hypoderma spp infestation. Necropsy inspection of slaughtered and skinned animals were carried out by examination of the inner skin surface and subcutaneous tissues. Warbles were isolated by squeezing nodules from subcutaneous tissues. In the case of abscess presence, aseptic sample were taken from abscesses. The parasitological and bacteriological examinations were performed on the samples. The results indicated that 104 out of 958 of slaughtered animals were infested to Hypoderma spp in which 48 (46.15 %, 34 (32.69 % and 22 (21.15 % were infested to Hypoderma bovis, Hypoderma lineatum and both species, respectively. Following bacterial analysis, the following bacteria were isolated: Escherichia coli, Streptococcus pyogenes, Staphylococcus aureus, Staphylococcus epidermidis and Klebsiella pneumonia.

  8. Rooting gene trees without outgroups: EP rooting.

    Sinsheimer, Janet S; Little, Roderick J A; Lake, James A


    Gene sequences are routinely used to determine the topologies of unrooted phylogenetic trees, but many of the most important questions in evolution require knowing both the topologies and the roots of trees. However, general algorithms for calculating rooted trees from gene and genomic sequences in the absence of gene paralogs are few. Using the principles of evolutionary parsimony (EP) (Lake JA. 1987a. A rate-independent technique for analysis of nucleic acid sequences: evolutionary parsimony. Mol Biol Evol. 4:167-181) and its extensions (Cavender, J. 1989. Mechanized derivation of linear invariants. Mol Biol Evol. 6:301-316; Nguyen T, Speed TP. 1992. A derivation of all linear invariants for a nonbalanced transversion model. J Mol Evol. 35:60-76), we explicitly enumerate all linear invariants that solely contain rooting information and derive algorithms for rooting gene trees directly from gene and genomic sequences. These new EP linear rooting invariants allow one to determine rooted trees, even in the complete absence of outgroups and gene paralogs. EP rooting invariants are explicitly derived for three taxon trees, and rules for their extension to four or more taxa are provided. The method is demonstrated using 18S ribosomal DNA to illustrate how the new animal phylogeny (Aguinaldo AMA et al. 1997. Evidence for a clade of nematodes, arthropods, and other moulting animals. Nature 387:489-493; Lake JA. 1990. Origin of the metazoa. Proc Natl Acad Sci USA 87:763-766) may be rooted directly from sequences, even when they are short and paralogs are unavailable. These results are consistent with the current root (Philippe H et al. 2011. Acoelomorph flatworms are deuterostomes related to Xenoturbella. Nature 470:255-260).

  9. Zinc Oxide Eugenol-Formocresol Root Canal Treatment Fails to Treat a Deciduous Tooth with Dentoalveolar Abcess

    Arifa Pediarahma


    Full Text Available Irreversible pulp infection can lead to dentoalveolar abscess. Root canal treatment in deciduous teeth is indicated in irreversible pulp infection to maintain children’s health and deciduous teeth until its exfoliation period. Success rate of endodontic treatment in deciduous teeth can be enhanced by using antimicrobial root canal filling material. Combination of ZOE-formocresol as root canal filling material has a superior antimicrobial property. Unfortunately, based on some research it is also toxic to the tissue. This case report will discuss about failure of root canal treatment in deciduous tooth with dentoalveolar abscess using combination of ZOE-formocresol as obturating material. There are some factors that possibly cause the failure: complexity of deciduous molar anatomy, the choice of root canal filling material, application of root canal filling material that is not adequate, or an extend pathological condition.DOI:10.14693/jdi.v21i3.230

  10. Is pulp regeneration necessary for root maturation?

    Nosrat, Ali; Li, Kevin L; Vir, Kunwar; Hicks, M Lamar; Fouad, Ashraf F


    True regeneration of the dental pulp-dentin complex in immature teeth with necrotic pulps has not been shown histologically. It is not known to what extent this true tissue regeneration is necessary to achieve clinically acceptable outcomes. This case report describes the treatment of a patient with an immature maxillary right central incisor with a history of impact trauma and enamel-dentin crown fracture. A diagnosis of pulp necrosis with acute apical abscess was established. A regenerative endodontic protocol that used a paste containing Augmentin for 5 weeks as an intracanal medicament was used. Follow-ups at 9, 12, 17, and 31 months revealed complete osseous healing of the periapical lesion and formation of the root apex, but without increase in root length. Clinically, the tooth was functional, asymptomatic, and nonresponsive to pulp vitality tests. The crown discolored over time. On reentering the root canal, no tissues were observed under magnification inside the root canal space. The root canal treatment was completed with mineral trioxide aggregate obturation. Augmentin might be an acceptable choice for root canal disinfection in regenerative endodontic procedures. The protocol for regenerative endodontic treatment is not predictable for pulp-dentin regeneration. Formation of the root apex is possible without pulp regeneration.

  11. 肛旁脓肿的术式选择%The selections of surgical procedures in perianal abscess

    梅世文; 金黑鹰


    Perianal abscess is the most common disease in anal, almost in man. It is caused by infections of anal glands, and the inflammations spread to the perianal gap, eventually abscess formation in perianal. There are a number of perianal abscess diseases caused by systemic diseases, such as inflammatory bowel disease, cancer and hematological system diseases. Whatever the perianal abscess arises from the infection of anal glands or the systemic diseases, in common, the strategy of therapy is incision and drainage. But after incision and drainage, the formation of fistula rate is higher. Abscess often spread widely in perianal, so improper surgical treatment may cause potentially residual cavity, leading to recurrent abscess and fistula formation. according to the characteristics of the anatomy around the anus, The author takes″three cavity clearance″ to drainage the perianal abscess completely, and achieves certain results. The Commentary will discuss the perianal abscess surgical options.%肛周脓肿是肛门部最常见疾病,青年男性多见,发病率较高,多由肛腺感染引起,向肛周间隙蔓延,最终形成脓肿。还有一些全身性疾病引起的肛周脓肿,例如炎症性肠病,血液肿瘤等。肛周脓肿无论是原发于肛腺感染还是全身疾病导致局部脓肿,目前公认的治疗方案为肛周脓肿的切开引流,同时也符合外科感染的治疗原则。但切开引流术后肛瘘的形成率较高,肛门部脓肿常无固定,手术处理不当可能将潜在腔系残留,导致脓肿的复发及肛瘘形成。笔者根据肛门周围解剖结构的特点,采用“三间隙引流”对肛周脓肿行彻底的敞开引流,取得了一定的效果。本述评就肛周脓肿的术式选择展开论述。

  12. Medtronic Freestyle Aortic Root Bioprosthesis Implantation for the Infective Endocarditis on Aortic Root

    Zekeriya Arslan


    Full Text Available    Infective endocarditis and periannular abscess formation are serious problems in cardiac valve surgery, requiring extensive surgical debridement and reconstruction of the aortic annulus. We aimed to report two cases which were successfully treated with bioprosthetic valve implantation for infective endocarditis. Transosephageal echocardiography were performed for the diagnosis of one prosthetic and one native destructive aortic valve endocarditis in association with congestive heart failure (NYHA class-VI and abscess formation. Medtronic Freestyle stentless aortic root bioprosthesis was implanted into the left ventricular outflow tract after surgical radical aortic root debridement for each patient followed with medical treatment, which was extended to six weeks. Neither early nor late mortality was detected. One patient required prolonged ventilatory support (two days and permanent DDD-R pacing. Echocardiography showed no signs of valve dysfunction or recurrent endocarditis for both patients in 10 months follow up.Medtronic Freestyle stentless aortic root bioprosthesis may be a good alternative way of treatment to aortic valve and root endocarditis instead of homograft.

  13. Dynamics of breast milk HIV-1 RNA with unilateral mastitis or abscess

    Semrau, Katherine; Kuhn, Louise; Brooks, Daniel R.; Cabral, Howard; Sinkala, Moses; Kankasa, Chipepo; Thea, Donald M.; Aldrovandi, Grace M.


    Background Mastitis and abscess in HIV-infected women increase 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. Methods HIV RNA was quantified in 211 breast milk samples collected before, during and after a clinical mastitis or 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. Results In the affected breast, breast milk HIV RNA quantity increased from the pre- to during-pathology period by log10 0.45 copies/mL (95% CI: 0.16, 0.74) and after symptom resolution, HIV RNA levels were no different from pre-pathology levels (log10 -0.04 copies/mL 95%CI: -0.33, 0.25). In the contralateral unaffected breast, HIV RNA quantity did not significantly increase (log10 0.15 copies/mL, 95% CI: -0.41, 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. Conclusions Breast milk HIV RNA increased modestly in the affected breast with unilateral mastitis or abscess and returned to pre-pathology levels with symptom resolution. Contralateral HIV RNA was not affected. Results support guidelines encouraging feeding from the contralateral breast to minimize risk of HIV transmission associated with unilateral breast pathology.

  14. [Paratonsillar abscess in the patients presenting with the non-anginous form of chronic tonsillitis].

    Arzamazov, C G; Ivanets, I V


    The present study was undertaken for the purpose of the comparative analysis of the degree of severity and inflammation-induced changes in palatine tonsils of the patients presenting with non-anginous forms of chronic tonsillitis both on the side of development of paratonsillitis and on the opposite side showing no visually visible signs of the acute inflammatory process. The secondary objective of the study was to compare pain syndrome during abscess-tonsillectomy and tonsillectomy proper, respectively. We analysed the causes behind the reduction of the total number of tonsillectomies for the treatment of chronic tonsillitis available from the accessible literature for the past 10 years. Moreover the analysis of medical records of the patients with chronic tonsillitis and delayed paratonsillar abscess was performed based on the results of the treatment of the patients admitted to the Otorhinolaryngological Department of the City Clinical Hospital No 1 during the period from 2002 and 2011. The severity of clinical manifestations of the inflammatory process was estimated based on the study of palatine tonsil biopsies removed during surgery using the radioautographic technique. The severity of pain syndrome during abscess-tonsillectomy and tonsillectomy proper was evaluated based on the McGill pain questionnaire. The results of the study confirmed apparent tonsillar inflammation in the patients presenting with chronic tonsillitis including its non-anginous forms.

    Mustafa Yildiz; Ahmet Sevki Karakayali; Saadet Ozer; Hilal Ozer; Aydin Demir; Bugra Kaptanoglu


    We report a case of right lower abdominal wall and groin abscess resulting from acute appendicitis. The patient was an 27-year-old man who had no apparent abdominal signs and was brought to the hospital due to progressive painful swelling of right lower abdomen and the groin for 10 d. Significant inflammatory changes of soft tissue involving the right lower trunk were noted without any apparent signs of peritonitis. Laboratory results revealed leukocytosis. Abdominal ultrasonography described the presence of abscess at right inguinal site also communicating with the intraabdominal region. Right inguinal exploration and laparotomy were performed and about 250 mL of pus was drained from the subcutaneous tissue and preperitoneal space. No collection of pus was found intraabdominally and subserous acute appendicitis was the cause of the abscess. The patient fully recovered at the end of the second post-operation week. This case reminds us that acute appendicitis may have an atypical clinical presentation and should be treated carefully on an emergency basis to avoid serious complications.

  16. Bacteroides fragilis in biopsies of patients with major abscesses and diabetic foot infections: direct molecular versus culture-based detection

    Stappers, Mark H. T.; Hagen, Ferry; Reimnitz, Peter; Mouton, Johan W.; Meis, Jacques F.; Gyssens, Inge C


    Direct determination by pathogen-specific real-time PCR assay for Bacteroides fragilis was compared to culture in major abscess and diabetic foot infection biopsy samples. Real-time PCR resulted in an increased detection rate of 12% for B. fragilis and could improve the detection of B. fragilis in clinical samples. (C) 2016 Elsevier Inc. All rights reserved.

  17. Retropharyngeal Calcific Tendonitis Mimics a Retropharyngeal Abscess

    Natasha Pollak


    Full Text Available Retropharyngeal calcific tendonitis (RCT is an uncommon, self-limiting condition that is often omitted in the differential diagnosis of a retropharyngeal fluid collection. This condition mimics a retropharyngeal abscess and should be considered when evaluating a fluid collection in the retropharyngeal space. Although calcific tendonitis at other sites has been well described in the medical literature, it appears that this entity has been underreported in the otolaryngology literature where only a few case reports have been identified. Presumably, the actual incidence is higher than the reported incidence, due to lack of familiarity with this disorder. As an otolaryngologist’s scope of practice includes the managements of retropharyngeal lesions, it is important for the otolaryngologist to recognize the presentation of acute RCT and be familiar with appropriate treatment strategies. Retropharyngeal calcific tendonitis presents with neck pain, limitation of neck range of motion and includes inflammation, calcifications, and a sterile effusion within the longus colli muscle. Treatment is medical with nonsteroidal anti-inflammatory medications. RCT does not require surgical treatment, and an accurate diagnosis can prevent unnecessary attempts at operative drainage. In this study, we discuss two cases of RCT, summarize the salient features in diagnosis, including key radiologic features, discuss treatment options, and review the literature.

  18. [Abscess, fistula and occlusion of colonic diverticulosis].

    Bouillot, J L


    Diverticular disease is generally benign but may be serious in case of septic complications. The most common complication of acute diverticulitis is development of an abscess which can be located around the colon or in the pelvis. The diagnosis can be clinically suspected in case of non-response to medical management of severe acute diverticulitis. Confirmation is obtained by conventional radiographic examinations and computerized tomography. This condition can be safely treated by percutaneous catheter drainage associated to antibiotics followed by an elective delayed single-stage operation without colostomy. Fistula occurs in 20% of the patients who undergo surgery for diverticular disease. Colovesical fistula is the most common type of spontaneous internal fistula. Routine evaluation may raise the suspicion of complication. Surgical management requires colonic resection and primary anastomosis. Complete obstruction secondary to diverticular disease is uncommon and generally resolves with conservative management. However, some degree of ileus is frequent secondary to inflammatory changes of diverticulitis but should imperatively be differentiated from ileus observed in case of generalized peritonitis.

  19. Experimental amoebic liver abscess in hamsters caused by trophozoites of a Brazilian strain of Entamoeba dispar.

    Guzmán-Silva, Maria Angélica; Santos, Helena Lúcia Carneiro; Peralta, Regina Saramago; Peralta, José Mauro; de Macedo, Heloisa Werneck


    It has been claimed that amoebic molecules such as amoebapore, galactose/N-acetyl galactosamine inhibitable lectin, and cysteine proteases are responsible for host tissue destruction and are present in both pathogenic Entamoeba histolytica and non-pathogenic Entamoeba dispar. Some reports have provided evidence that after infection with E. dispar, pathological changes may occur in some humans. The aim of this study was to evaluate E. dispar pathogenicity by comparing it to the pathogenicity of E. histolytica through liver abscesses induced in hamsters. Syrian golden hamsters were challenged by intrahepatic inoculation with the 03C E. dispar strain or with two strains of E. histolytica (HM1:IMSS and EGG) to compare their virulence grades. As control groups, we used bacterial flora and Pavlova's modified medium. Lesions were verified at 1, 3 and 6 days after inoculation. Multiplex Polymerase Chain Reaction was performed to characterize each strain using EdP1/EdP2 and EhP1/EhP2 primers. The EGG and HM1:IMSS E. histolytica strains and 03C E. dispar were able to cause liver lesions. The EGG strain caused extensive hepatic abscesses, and trophozoites were found in the lesions throughout the three periods of study. The HM1:IMSS strain caused smaller abscesses when compared to EGG lesions; however, trophozoites were observed at 1 and 3 days after inoculation. The 03C E. dispar strain caused intermediate abscesses when compared to the others; trophozoites were observed in all periods analyzed. The EGG strain caused progressive evolution of the injury, which differed from the HM1:IMSS and 03C strains. These results strongly suggest that the 03C E. dispar strain is pathogenic in the experimental hamster model. Additional studies are necessary to identify potential factors that regulate the manifestation of virulence of this strain and others. Copyright © 2013 Elsevier Inc. All rights reserved.

    Jin-Fu Tu; Xiu-Fang Huang; Ru-Ying Hu; He-Yi You; Xiao-Feng Zheng; Fei-Zhao Jiang


    AIM:To investigate the feasibility and therapeutic effect of laparoscopic surgery for pyogenic liver abscess (PLA) with biliary pathology.METHODS:From January 2004 to October 2010,31 patients with PLA combined with biliary pathology meeting entry criteria received surgical management in our hospital.Of the 31 patients,13 underwent laparoscopic surgery (LS group) and 18 underwent open surgery (OS group).Clinical data including operation time,intraoperative blood loss,postoperative complication rate,length of postoperative hospital stay,and abscess recurrence rate were retrospectively analyzed and compared between the two groups.RESULTS:All patients received systemic antibiotic therapy.Four patients underwent ultrasound-guided percutaneous catheter drainage before operation.Postoperative complications occurred in 5 patients (16.1%,5/31) including 2 in the LS group and 3 in the OS group.One patient had retained calculus in the common bile duct and another had liver abscess recurrence in the OS group.No retained calculus and liver abscessrecurrence occurred in the LS group.In the two groups,there was no mortality during the perioperative period.There were no significant differences in operation time,intraoperative blood loss and transfusion,postoperative complication rate and abscess recurrence rate between the two groups.Oral intake was earlier (1.9 ± 0.4 d vs 3.1 ± 0.7 d,P < 0.05) and length of postoperative hospital stay was shorter (11.3 ± 2.9 d vs 14.5 ± 3.7 d,P < 0.05) in the LS group than in the OS group.CONCLUSION:Laparoscopic surgery for simultaneous treatment of PLA and biliary pathology is feasible in selected patients and the therapeutic effect is similar to that of open surgery.

  1. Delayed diagnosis of central skull-base osteomyelitis with abscess: case report and learning points.

    Chawdhary, G; Hussain, S; Corbridge, R


    Central skull-base osteomyelitis (CSBO) is a rare life-threatening infection, usually resulting from medial spread of necrotising otitis externa. Here, we describe a case with no identifiable source of infection, causing a delay in diagnosis. An 80-year-old man with Crohn's disease treated with mesalazine presented with collapse and tonic-clonic seizure. Computed tomography and magnetic resonance imaging showed a nasopharyngeal mass that was initially thought to be a neoplasm. Awaiting formal biopsy, he represented with collapse and repeat imaging showed features of abscess formation. Review of previous scans revealed skull-base erosion and the diagnosis was revised to skull-base osteomyelitis. This is the first reported case of CSBO associated with mesalazine use, an aminosalicylate used in Crohn's disease. It is only the second reported case with abscess formation. We discuss the learning points in making a timely diagnosis and examine the potential association of factors such as mesalazine use and abscess formation in this case.

  2. Primary osteosarcoma of the breast presented as a large breast abscess

    N J Nawarathna


    Full Text Available Primary extra osseous osteogenic sarcoma is one of the rarest forms of malignant tumor of the breast. It can arise as a result of osseous metaplasia of a preexisting neoplasm or from a none - phyllodes sarcoma of a previously normal breast. Due to its rarity, natural history and optimal treatment methods remain unclear. A 60-year-old patient presented to the surgical casualty with large breast abscess. Abscess wall histology revealed an osteosarcoma of the breast. Left total mastectomy with axillary clearance was performed. Histology and subsequent immunohistochemical studies confirmed the diagnosis of osteogenic sarcoma without lymph nodal metastasis. The patient was referred to the oncologist for further management. Rare types of breast tumors can be presented as breast abscess. Incision and drainage together with wall biopsy help to exclude associated sinister pathologies. Diagnosis of primary osteosarcoma of the breast was made using histological and immunohistochemical findings once the possible primary from the sternum and ribs were excluded. Treatment is as for sarcomas affecting other locations and should comprise a multidisciplinary approach.

    Othman, Nurulhasanah; Mohamed, Zeehaida; Yahya, Maya Mazuwin; Leow, Voon Meng; Lim, Boon Huat; Noordin, Rahmah


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

  4. A Case of Recurrent Skin Abscesses: A Conundrum Solved after Obtaining a Thorough Sexual History

    Diego P. Peralta


    Full Text Available Background. Despite the improvement in patient-physician communication techniques, sexuality and sexual health continue to be challenging areas for discussion during a clinical encounter. Most people are not prepared to discuss sexual matters openly as it can be perceived as negative or inappropriate. Consequently, an incomplete health assessment can result in delayed diagnosis or misdiagnosis. Case Report. We present a 33-year-old woman who developed recurrent left breast abscesses. She required multiple incision and drainage procedures in the operating room followed by antimicrobial therapy. Although she always had an initial improvement with this approach, she continued to have recurrences and development of new abscesses in other body areas. The polymicrobial nature of her recurrences prompted an extensive and costly workup to determine the nature of her condition. The cause was finally elucidated when a thorough sexual history was obtained. Poor hygiene practices during her sexual encounters were considered the cause of her recurrent abscesses. After medical therapy and modification of her sexual practices, she has not developed new recurrences for more than two years. Conclusion. Discussions on sexuality and sexual health are important parts of any clinical encounter, yet frequently forgotten or avoided. Becoming aware of their importance would avoid delayed diagnosis or misdiagnosis.

    Taro Osada; Akihito Nagahara; Tomohiro Kodani; Akihiro Namihisa; Masato Kawabe; Takashi Yoshizawa; Toshifumi Ohkusa; Sumio Watanabe


    Gastrointestinal stromai tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. In large GISTs, cystic degeneration, necrosis and focal hemorrhage that occur inside the tumor can result in gastrointestinal bleeding. We describe a case of a 74-year old male with GIST of the stomach accompanied with a giant abscess that penetrated the gastric lumen. The patient experienced undiagnosed fever for two months prior to hospitalization. Gastrointestinal endoscopy, X-ray series and computed tomography of the patient's abdomen revealed a gastric submucosal tumor in the fornix, with a fistula to the gastric lumen that was inundated with a great deal of pus. The mass was diagnosed as a GIST from biopsy specimens. The patient was treated by endoscopic drainage of the abscess and intravenous administration of antibiotics. Eventually, a partial gastrectomy was performed. He was also administered Imanitib mesylate as adjuvant therapy. He was followed up for 2 years and no metastasis or recurrence was recognized at the followup examinations. This is the first report of a patient with clearly diagnosed GIST with endoscopic evidence of an abscess penetrating into the gastric lumen.

  6. Multilevel analysis of clinical parameters in chronic periodontitis after root planing/scaling, surgery, and systemic and local antibiotics: 2-year results

    Ibrahimu Mdala


    Full Text Available Aim: Find the periodontal treatment that best maintained clinical results over time evaluated by changes in pocket depth (PD and clinical attachment level (CAL. Methods: 229 patients with chronic periodontitis from USA (n=134 and Sweden (n=95 were randomly assigned to eight groups receiving 1 scaling+root planing (SRP alone or combined with 2 surgery (SURG+systemic amoxicillin (AMOX+systemic metronidazole (MET; 3 SURG+local tetracycline (TET; 4 SURG; 5 AMOX+MET+TET; 6 AMOX+MET; 7 TET; and 8 SURG+AMOX+MET+TET. Antibiotics were given immediately after SRP. Plaque, gingival redness, bleeding on probing, suppuration, PD, and CAL were recorded at baseline and after 3, 6, 12, 18, and 24 months. Treatment effects were evaluated by linear multilevel regression and logistic multilevel regression models. We considered only data from sites with a baseline PD of at least 5 mm of 187 patients completing the study. Results: Surgically treated patients experienced most CAL loss. Adjunctive therapy including SURG was most effective in reducing PD. Combining SURG with AMOX, MET, and TET gave significant clinical benefits. Past and current smoking habits were significant predictors of deeper PD. Only current smoking was a significant predictor of CAL loss. Bleeding, accumulation of plaque, gingival redness, and suppuration were significant predictors of further CAL loss and deeper PD. Conclusions: Both surgical and non-surgical therapies can be used to arrest chronic periodontitis. SURG+AMOX+MET+TET gave best maintenance of clinical results.

  7. The management of an endodontically abscessed tooth: patient health state utility, decision-tree and economic analysis

    Shepperd Sasha


    Full Text Available Abstract Background A frequent encounter in clinical practice is the middle-aged adult patient complaining of a toothache caused by the spread of a carious infection into the tooth's endodontic complex. Decisions about the range of treatment options (conventional crown with a post and core technique (CC, a single tooth implant (STI, a conventional dental bridge (CDB, and a partial removable denture (RPD have to balance the prognosis, utility and cost. Little is know about the utility patients attach to the different treatment options for an endontically abscessed mandibular molar and maxillary incisor. We measured patients' dental-health-state utilities and ranking preferences of the treatment options for these dental problems. Methods Forty school teachers ranked their preferences for conventional crown with a post and core technique, a single tooth implant, a conventional dental bridge, and a partial removable denture using a standard gamble and willingness to pay. Data previously reported on treatment prognosis and direct "out-of-pocket" costs were used in a decision-tree and economic analysis Results The Standard Gamble utilities for the restoration of a mandibular 1st molar with either the conventional crown (CC, single-tooth-implant (STI, conventional dental bridge (CDB or removable-partial-denture (RPD were 74.47 [± 6.91], 78.60 [± 5.19], 76.22 [± 5.78], 64.80 [± 8.1] respectively (p The standard gamble utilities for the restoration of a maxillary central incisor with a CC, STI, CDB and RPD were 88.50 [± 6.12], 90.68 [± 3.41], 89.78 [± 3.81] and 91.10 [± 3.57] respectively (p > 0.05. Their respective willingness-to-pay ($CDN were: 1,782.05 [± 361.42], 1,871.79 [± 349.44], 1,605.13 [± 348.10] and 1,351.28 [± 368.62]. A statistical difference was found between the utility of treating a maxillary central incisor and mandibular 1st-molar (p The expected-utility-value for a 5-year prosthetic survival was highest for the CDB and the

    Flavio Akira Sakae


    Full Text Available OBJETIVO: O objetivo deste estudo é avaliar a microbiologia dos abscessos periamigdalianos. MATERIAIS E MÉTODOS: Trinta pacientes com diagnóstico de abscesso periamigdaliano, idade média de 24,2 anos, foram submetidos à punção na região periamigdaliana de maior abaulamento com aspiração do material purulento (volume maior que 3mL. O material foi separado para realização das culturas aeróbicas e anaeróbicas. RESULTADOS: Houve um índice de positividade das culturas de 86,7%. Em 23,3% aspirados houve crescimento apenas de bactérias aeróbicas ou facultativas, 3,3% apenas de bactérias anaeróbicas e por fim em 60% aspirados houve crescimento de bactérias aeróbicas e anaeróbicas. Um total de 69 bactérias foi isolado (34 aeróbios e 35 anaeróbios. Os aeróbios predominantes foram Streptococcus sp, sendo o Streptococcus pyogenes em 23% dos casos. Os anaeróbios predominantes foram Prevotella sp e Peptostreptococcus sp. Pacientes receberam antibiótico prévio em 63% dos casos. Neste grupo foram isolados 1,8 bactérias por aspirado, menor número que nos paciente que não utilizaram antibiótico (3,0 bactérias por aspirado. Não houve diferença significativa no tipo de bactéria isolada nestes dois grupos. CONCLUSÃO: Os abscessos periamigdalianos apresentam na maioria dos casos infecções polimicrobianas, sendo os organismos anaeróbicos agentes importantes. O número de agentes isolados é maior nos pacientes que não utilizaram antibioticoterapia prévia, mas o uso de antimicrobiano não interferiu no tipo de bactéria isolada.AIM: The objective of the present study was to analyze the microbiology of peritonsillar abscesses. METHODS: Thirty patients, mean age 24,2 years, with peritonsillar abscesses underwent aspiration of at least 3 mL of pus, which was cultured for aerobes and anaerobes. RESULTS: 87% samples showed positive cultures. Aerobic or facultative aerobic bacteria were isolated from 23% aspirates, mixed aerobic and

  9. Late evolution retropharyngeal abscess after ingestion of foreign body

    Imamura, Rui


    Full Text Available Introduction: The complications relating to the ingestion of foreign bodies, such as retropharyngeal abscess, are of low prevalence, but potentially severe. Objective: To present one case of late evolution retropharyngeal abscess after ingestion of foreign body. Case Report: Female patient presenting with dysphagia, pain upon cervical motion and sensation of foreign body in the pharynx, about one month after removal of foreign body from the level of the cricopharyngeal muscle. In spite of not having fever or leukocytosis, due to the slight difficulty for cervical move and loss of the laryngeal crepitation, simple radiography and computed tomography were carried out in the neck, which showed signs of retropharyngeal abscess. Surgical draining of the abscess and antibiotic therapy led to good evolution of the case and symptoms reversion. Conclusion: The retropharyngeal abscess may occur during several weeks after ingestion of a foreign body. The absence of fever and leukocytosis does not exclude the diagnosis even in immunocompetent patients. A high degree of suspicion leads to the performance of diagnostic exams and suitable procedures.

  10. Healed perivalvular abscess: Incidental finding on transthoracic echocardiography

    Vishnu Datt


    Full Text Available A 36-year-old male patient presented with the complaints of palpitations and breathlessness. Preoperative transthoracic echocardiography (TTE revealed a bicuspid aortic valve; severe aortic regurgitation with dilated left ventricle (LV and mild LV systolic dysfunction (ejection fraction 50%. He was scheduled to undergo aortic valve replacement. History was not suggestive of infective endocarditis (IE. Preoperative TTE did not demonstrate any aortic perivalvular abscess. Intraoperative transesophageal echocardiography (TEE examination using the mid-esophageal (ME long-axis view, showed an abscess cavity affecting the aortic valve, which initially was assumed to be a dissection flap, but later confirmed to be an abscess cavity by color Doppler examination. The ME aortic valve short-axis view showed two abscesses; one was at the junction of the non-coronary and left coronary commissure and the other one above the right coronary cusp. Intraoperatively, these findings were confirmed by the surgeons. The case report demonstrates the superiority of TEE over TTE in diagnosing perivalvular abscesses.

  11. Epidural abscess caused by Streptococcus milleri in a pregnant woman

    Bearman Gonzalo


    Full Text Available Abstract Background Bacteria in the Streptococcus milleri group (S. anginosus, S. constellatus, and S. intermedius are associated with bacteremia and abscess formation. While most reports of Streptococcus milleri group (SMG infection occur in patients with underlying medical conditions, SMG infections during pregnancy have been documented. However, SMG infections in pregnant women are associated with either neonatal or maternal puerperal sepsis. Albeit rare, S. milleri spinal-epidural abscess in pregnancy has been reported, always as a complication of spinal-epidural anesthesia. We report a case of spinal-epidural abscess caused by SMG in a young, pregnant woman without an antecedent history of spinal epidural anesthesia and without any underlying risk factors for invasive streptococcal disease. Case presentation A 25 year old pregnant woman developed neurological symptoms consistent with spinal cord compression at 20 weeks gestation. She underwent emergency laminectomy for decompression and was treated with ceftriaxone 2 gm IV daily for 28 days. She was ambulatory at the time of discharge from the inpatient rehabilitation unit with residual lower extremity weakness. Conclusion To our knowledge, this is the first reported case of a Streptococcus milleri epidural abscess in a healthy, pregnant woman with no history of epidural anesthesia or invasive procedures. This report adds to the body of literature on SMG invasive infections. Treatment of SMG spinal-epidural abscess with neurologic manifestations should include prompt and aggressive surgical decompression coupled with targeted anti-infective therapy.

  12. Fistulotomy and drainage of deep postanal space abscess in the treatment of posterior horseshoe fistula

    Gencosmanoglu Rasim


    Full Text Available Abstract Background Posterior horseshoe fistula with deep postanal space abscess is a complex disease. Most patients have a history of anorectal abscess drainage or surgery for fistula-in-ano. Methods Twenty-five patients who underwent surgery for posterior horseshoe fistula with deep postanal space abscess were analyzed retrospectively with respect to age, gender, previous surgery for fistula-in-ano, number of external openings, diagnostic studies, concordance between preoperative studies and operative findings for the extent of disease, operating time, healing time, complications, and recurrence. Results There were 22 (88% men and 3 (12% women with a median age of 37 (range, 25–58 years. The median duration of disease was 13 (range, 3–96 months. There was one external opening in 12 (48% patients, 2 in 8 (32%, 3 in 4 (16%, and 4 in 1 (4%. Preoperative diagnosis of horseshoe fistula was made by contrast fistulography in 4 (16% patients, by ultrasound in 3 (12%, by magnetic resonance imaging in 6 (24%, and by physical examination only in the remainder (48%. The mean ± SD operating time was 47 ± 10 min. The mean ± SD healing time was 12 ± 3 weeks. Three of the 25 patients (12% had diabetes mellitus type II. Nineteen (76% patients had undergone previous surgery for fistula-in-ano, while five (20% had only perianal abscess drainage. Neither morbidity nor mortality developed. All patients were followed up for a median of 35 (range, 6–78 months and no recurrence was observed. Conclusions Fistulotomy of the tracts along the arms of horseshoe fistula and drainage of the deep postanal space abscess with posterior midline incision that severs both the lower edge of the internal sphincter and the subcutaneous external sphincter and divides the superficial external sphincter into halves gives excellent results with no recurrence. When it is necessary, severing the halves of the superficial external sphincter unilaterally or even bilaterally in the

  14. Low-Grade Astrocytoma Associated with Abscess Formation: Case Report and Literature Review

    Tai-Hsin Tsai


    Full Text Available A rare case of low-grade astrocytoma associated with abscess formation occurred in a 52-year-old man presenting with Broca's aphasia. He underwent craniotomy and tumor removal under the impression of brain tumor with necrotic cystic change. Abscess accumulation within the intra-axial tumor was found intraoperatively. Literature related to brain abscess with brain tumor is reviewed, with an emphasis on abscesses with astrocytoma. We discuss the common brain tumors that are associated with abscess, pathogens that coexist with brain tumor, and the pathogeneses of coexisting brain abscess and tumor. It is very important to know how to differentiate between and diagnose a brain abscess and tumor, or brain abscess with tumor, preoperatively from clinical presentation and through the use of computed tomography, conventional magnetic resonance imaging, diffusion-weighted imaging or magnetic resonance spectroscopy.

  15. Detection of excretory Entamoeba histolytica DNA in the urine, and detection of E. histolytica DNA and lectin antigen in the liver abscess pus for the diagnosis of amoebic liver abscess

    Khairnar Krishna


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

  16. Percutaneous abscess drainage in Crohn`s disease; Perkutane Abszessdrainage bei Morbus Crohn

    Strotzer, M.; Manke, C.; Feuerbach, S. [Klinikum der Univ. Regensburg (Germany). Inst. fuer Roentgendiagnostik; Lock, G.; Bregenzer, N.; Schoelmerich, J. [Klinikum der Univ. Regensburg (Germany). Klinik und Poliklinik fuer Innere Medizin I


    Purpose: To evaluate the success of percutaneous, CT-guided abscess drainage (PAD) in patients with Crohn`s disease. Methods: Within the last 5 years 8 patients with Crohn`s disease were treated by PAD for intra-abdominal abscesses. A fistula was determined to be the cause in 4 patients. The abscesses arose spontaneously in 7 patients while one patient had a postperative abscess. We used single lumen 10F- and double lumen 12F- and 14F-catheters for drainage (duration of drainage 8-20 days). Results: In all cases the abscess was successfully drained by PAD. However, an operation-free interval of at least three months was achieved in only two patients. A healing of the fistula was not attained in any of the 4 patients with a proven fistula. No enterocutaneous fistulas arose within the course of PAD. Conclusions: PAD is also useful for patients with Crohn`s disease since it improves the starting situation for the necessary operative interventions. In most cases (especially with enterogenic fistulas), however, a long-lasting therapeutic result cannot be expected. (orig.) [Deutsch] Ziel: Bewertung des Erfolges der perkutanen CT-gezielten Abszessdrainage (PAD) bei Patienten mit Morbus Crohn. Methoden: 8 Patienten mit Morbus Crohn wurden innerhalb der letzten 5 Jahre wegen intraabdomineller Abszesse mittels PAD behandelt. Als Ursache wurde bei 4 Patienten eine Fistel nachgewiesen. Bei 7 Patienten waren die Abszesse spontan entstanden, bei einem Patienten handelte es sich um einen postoperativen Abszess. Zum Einsatz kamen einlumige 10F- und doppellumige 12F- und 14F-Drainagekatheter (Drainagedauer 8-20 Tage). Ergebnisse: In allen Faellen konnte durch die PAD eine Entlastung der Abszesse erzielt werden. Ein operationsfreies Intervall von mindestens drei Monaten wurde nur bei zwei Patienten erreicht. Bei keinem der 4 Patienten mit Fistelnachweis wurde eine Ausheilung der Fistel erreicht. Es kam im Rahmen der PAD zu keiner Bildung von enterokutanen Fisteln. Schlussfolgerungen

  18. Pyogenic liver abscess in beta-thalassemia major--report of two cases.

    Hwang, C F; Lee, C Y; Lee, P I; Chen, J M; Lli, K H; Lin, D T; Chang, M H


    Pyogenic liver abscess, which may lead to devastating consequences, is an uncommon medical problem in pediatrics and has generally been reported in compromised hosts. This article describes two patients with beta-thalassemia major and hemochromatosis complicated by Klebsiella pneumoniae liver abscess. One of the patients had severe complications, including subphrenic abscess, pleural effusion and meningitis. To present knowledge, the occurrence of K. pneumoniae liver abscess in patients with beta-thalassemia major has never before been reported in the literature.

  19. Aseptic Splenic Abscess as Precursory Extraintestinal Manifestation of Inflammatory Bowel Disease

    Full Text Available Splenic abscesses are most often secondary to aerobic bacterial infections due to Streptococcus, Staphylococcus, and Enterococcus species of organisms. Sterile splenic abscesses rarely occur and diagnosis and treatment of those are challenging. We report a case of a previously healthy young female presenting with aseptic splenic abscesses as the initial manifestation of Crohn’s disease along with a review of the literature on aseptic splenic abscess as an extraintestinal manifestation of Crohn’s disease.

  20. Root resorption

    Kjaer, Inger


    Introduction: This paper summarizes the different conditions, which have a well-known influence on the resorption of tooth roots, exemplified by trauma and orthodontic treatment. The concept of the paper is to summarize and explain symptoms and signs of importance for avoiding resorption during...... orthodontic treatment. The Hypothesis: The hypothesis in this paper is that three different tissue layers covering the root in the so-called periroot sheet can explain signs and symptoms of importance for avoiding root resorption during orthodontic treatment. These different tissue layers are; outermost...... processes provoked by trauma and orthodontic pressure. Inflammatory reactions are followed by resorptive processes in the periroot sheet and along the root surface. Evaluation of the Hypothesis: Different morphologies in the dentition are signs of abnormal epithelium or an abnormal mesodermal layer. It has...
