1/31. Inguinal lymphadenitis caused by entamoeba histolytica: case report and literature review.liver abscesses are the most common manifestation of extraintestinal infection by entamoeba histolytica. Involvement of other sites, including the peritoneum, pericardium, brain, or genitourinary tract, is unusual. We describe a case of inguinal necrotizing lymphadenitis caused by E histolytica. Our patient responded well to surgical drainage, metronidazole, and paramomycin therapy. A literature review of genitourinary and other uncommon sites of E histolytica infection is included.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
2/31. Mediastinal histoplasmosis with abscess.A mediastinal mass of clinically undetermined nature was found at autopsy to be an enormous abcess due to secondary infection in granulamatous caseating mediastinal nodes caused by Hitosplasma capsulatum. Other complications of mediastinal histoplasmosis are briefly reviewed.- - - - - - - - - - ranking = 4keywords = abscess (Clic here for more details about this article) |
3/31. Disseminated Mycobacterium abscessus infection manifesting as fever of unknown origin and intra-abdominal lymphadenitis: case report and literature review.Mycobacterium abscessus is a rapidly growing mycobacterium found in soil and water throughout the world. Disease in immunocompetent patients usually consists of localized skin and soft tissue infections. In contrast, disseminated disease is uncommon, usually presents with rash, and almost always occurs in an immunocompromised host. We describe an unusual case of disseminated M. abscessus infection manifesting as fever of unknown origin and intra-abdominal lymphadenitis, but without rash. Our patient responded well to amikacin and clarithromycin therapy. We also review the literature related to the diagnosis and management of this uncommon disease.- - - - - - - - - - ranking = 6keywords = abscess (Clic here for more details about this article) |
4/31. Cervical lymphadenitis--a rare case of focal listeriosis.Cervical lymphadenopathy is a condition with a broad differential diagnosis. Malignant tumors, allergic reactions, autoimmune diseases as well as various infectious agents can be the cause. We report the case of a 75-year-old man who had a cervical lymphadenopathy without symptoms of infection. The draining lymph nodes were excised. histology revealed a granulomatous abscess and culture yielded pure growth of listeria monocytogenes. Because food is occasionally contaminated with L. monocytogenes, the pathogenesis of this condition may be similar to that of lymph node tuberculosis.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
5/31. The supratrochlear lymph nodes: their diagnostic significance in a swollen elbow joint.In the differential diagnosis of a swollen elbow, the palpation of the supratrochlear glands is useful. They are not enlarged in a traumatic elbow joint. They are enlarged, discrete and shotty in rheumatoid arthritis. In tuberculosis, they are enlarged, matted and they may caseate and form a cold abscess on the medial aspect of the supratrochlear region of the arm.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
6/31. Atypical mycobacterial tuberculosis--a diagnostic and therapeutic dilemma? case reports and review of the literature.In immunocompetent preschool children cervical lymphadenitis is a common clinical presentation of atypical mycobacteria. Its rapid diagnosis and treatment is still a challenge, because accurate diagnostic procedures for atypical mycobacteria are still not yet available in routine practice. Two children suffered from craniojugular (16 months old girl) and infraauricular (2.5 years old boy) located neck masses which showed resistance to the medical treatment. In the first case an abscess splitting took place initially, followed by an anti-tubercular drug treatment and necessary surgical reintervention. In the second case surgical removal of all involved lymph nodes, infiltrated surrounding soft tissue and involved skin areas were followed by medical treatment. In both cases presumed infection with mycobacterium tuberculosis was not confirmed, but atypical mycobacteria could be isolated both. In the first case atypical mycobacterium could be specified as mycobacterium avium complex and in the second case as mycobacterium malmoense. Both bacilli showed sensitivity towards medical treatment with clarithromycin, whereby in one case only the surgical reintervention led to a complete removal of clinical symptomatic. In cases of presumed tuberculous neck lymph node infections differential diagnosis of an atypical mycobacterial lymphadenitis should always be supposed, because medical and surgical treatment differ fundamentally.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
7/31. Cat scratch disease with lymphadenitis, vertebral osteomyelitis, and spleen abscesses.In this report we describe a 30-year old male patient with vertebral osteomyelitis and spleen abscesses with cat scratch disease. The diagnosis was made on the basis of molecular detection of bartonella henselae either on lymph node biopsies or on bone biopsy, histology of the lymph node, serology using either our in-house microimmunofluorescence assay or a commercial kit (Focus Technologies). Immunofluorescent detection was also performed directly on slide appositions using a monoclonal antibody. Treatment consisted of administration of antibiotics with rapid clinical improvement and a stabilization of skeletal lesions on the magnetic resonance imaging performed three months later. Twenty two other cases of this unusual manifestation associated with cat scratch disease have been reported in the literature and are reviewed here. Our case represents the second case of osteomyelitis associated with cat scratch disease in which B. henselae has been specifically identified as the etiological agent using several direct and indirect methods.- - - - - - - - - - ranking = 5keywords = abscess (Clic here for more details about this article) |
8/31. Recognition of retropharyngeal abscess in children.retropharyngeal abscess is a rare deep-neck infection that usually affects young children. Swelling in the neck can lead to sudden and fatal airway obstruction. Enlargement of lymph nodes located between the posterior pharyngeal wall and the prevertebral fascia occurs secondary to infection of the nasopharynx, paranasal sinuses or middle ear. Penetrating trauma or foreign-body penetration may also lead to abscess formation. Common symptoms include fever, swollen neck, difficult swallowing, muffled voice and hyperextension of the head and neck. Lateral neck radiographs confirm the diagnosis. Early surgical treatment prevents serious complications, such as mediastinal spread, aspiration of pus, airway obstruction or erosion into a major vessel.- - - - - - - - - - ranking = 6keywords = abscess (Clic here for more details about this article) |
9/31. Ultrastructure of Warthin-Starry stain-positive bacteria in abscess-forming reticular lymphadenitis.This study describes the ultrastructure of Warthin-Starry (WS) stain-positive bacteria in abscess-forming reticular lymphadenitis (ARL) compatible with cat scratch disease (CSD). Sections containing WS-positive bacteria were re-embedded in Epon, and semithin sections were examined by electron microscopy. silver particles were aggregated on the outer surfaces of the bacteria. Stereoscopic observations clearly showed that the bacteria were pleomorphic, rod-shaped, arranged in a row or at an angle, and frequently showed septal formation. Electron microscopy of ultrathin sections revealed that the cell wall possessed an outer membrane characteristic of gram-negative bacteria. The results indicate that rod-shaped bacteria with the WS-positive, gram-negative staining cause ARL histopathologically consistent with CSD.- - - - - - - - - - ranking = 5keywords = abscess (Clic here for more details about this article) |
10/31. Complications associated with the bacille Calmette-Guerin vaccination in ireland.INTRODUCTION: BCG vaccination is currently recommended for all newborns in ireland except where specifically contraindicated. This paper describes a marked increase in the number of referrals of patients with localised complications after vaccination to two Dublin paediatric hospitals. This increase coincided with the introduction of a new strain of bcg vaccine methods: A population surveillance study was undertaken to determine the frequency and spectrum of complications associated with the new strain of bcg vaccine introduced in ireland. patients were identified though review of the infectious disease service case records and microbiology laboratory culture reports for the two year period from August 2002 to July 2004. Prospectively gathered data were supplemented by retrospective chart review. All infants who had inoculation site abscesses, suppurative adenopathy, or non-suppurative adenopathy with nodes > or =2 cm were included. RESULTS: Fifty eight patients presented a median of 13 weeks post-inoculation: 32 with suppurative adenitis, 17 with inoculation site abscess, three with both inoculation site abscess and suppurative adenitis, and six with non-suppurative adenopathy. The overall complication rate was estimated at 1/931 vaccinees with 1/1543 developing suppurative adenitis. Twenty six infants required surgery. DISCUSSION: This series illustrates the role of hospitals in sentinel surveillance and highlights the importance of having a well functioning and responsive system of adverse event reporting. These events raise a serious question as to the suitability of this vaccine strain for use in a national immunisation programme in a country where the prevalence of tuberculous disease is 10.4/100,000.- - - - - - - - - - ranking = 3keywords = abscess (Clic here for more details about this article) |
