1/22. 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) |
2/22. Intestinal amebiasis: a diagnosis not to be missed.entamoeba histolytica is a well-recognized cause of infectious colitis and disseminated amebic abscesses. Most prevalent in the tropics and subtropics, E. histolytica infections may also occur in the developed world. We describe a case of a North American traveler with intestinal amebiasis, a diagnosis first made by colonic biopsy. We review the available diagnostic tools and the role of the surgical pathologist in the detection of this infection.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
3/22. Amebic abscess of urachal remnants.We report a rare case of amebic abscess of the urachus, mimicking an urachal neoplasm: no previous reports of amebic infection of the urachus were found in the literature. The challenges of the differential diagnosis between urachal abscess and carcinomas based both on clinical and radiological data are discussed.- - - - - - - - - - ranking = 6keywords = abscess (Clic here for more details about this article) |
4/22. Diagnostic dilemma in coinfection.A Fifteen years girl belonging to a low socioeconomic status was admitted with peritonsillar abscess caused by methicillin resistant staphylococcus aureus (MRSA), high fever, diarrhoea and septicaemic shock. Initial blood cultures and widal test, stool cultures and routine stool examination were non-contributory to the diagnosis. A bone marrow culture in the second week confirmed the diagnosis of salmonella typhi infection. Examination of a fresh stool sample showed cysts of entamoeba histolytica. She was treated with ciprofloxacin, metronidazole, augmentin and ceftriaxone. She had no clinical evidence of immunosuppression prior to this episode and her hiv test was negative. This case report highlights the presence of community acquired MRSA infection causing perititonsillar abscess, and the diagnostic dilemma of fever and diarrhoea due to coinfection with salmonella typhi and Entamobea histolytica.- - - - - - - - - - ranking = 2keywords = abscess (Clic here for more details about this article) |
5/22. Amebic pericarditis.Amebic pericarditis in a 40-year-old man who presented with insidious onset of symptoms is reported. pericarditis is an infrequent complication of liver abscess and accounts for 4 percent of all extraintestinal amebiasis. communication between the left lobe of liver and pericardium has been demonstrated in this patient.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
6/22. Emphysematous pyelonephritis and renal amoebiasis in a patient with diabetes mellitus.Emphysematous pyelonephritis is an uncommon and life-threatening infection of the kidney that is characterized by gas formation within or around the kidney and is associated with diabetes mellitus and urinary tract infection. Amoebiasis is a protozoal infection caused by entamoeba histolytica. In its invasive forms, the disease is characterized by visceral abscess formations. We present a case of concomitant emphysematous pyelonephritis and renal amoebiasis in a 42-year-old female with uncontrolled diabetes mellitus. The patient did not respond well to initial supportive treatment and antibiotherapy. Therefore, nephrectomy was performed. She did extremely well after the operation and was discharged with antidiabetics and antibiotics.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
7/22. Systemic manifestations of invasive amebiasis.Eighty-four patients with serious infection due to entamoeba histolytica were evaluated for systemic complications by objective criteria for dysfunction of the organ systems normally assessed in surgical sepsis. Of 71 patients with amebic liver abscess (ALA), 41% had systemic complications and 13% had more than one organ system involved. patients > or = 40 years of age and those being treated with steroids were at significantly increased risk of developing complications (P < or = .05). The erythrocyte sedimentation rate and the levels of the acute-phase markers c-reactive protein (CRP) and serum amyloid A (SAA) were significantly elevated in patients with ALA over values in those without ALA (P < or = .05). ALA patients with complications had lower CRP and SAA concentrations than those without complications (P < or = .05). blood and liver aspirates in ALA patients were usually bacteriologically sterile. The pathogenesis of systemic complications and the associated acute-phase response requires further study, and ways of predicting disease severity and intervening therapeutically must be devised.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
8/22. Amoebic psoas and liver abscesses.A 28 year old woman with a history of a dysenteric illness and documented campylobacter infection presented with amoebic psoas and liver abscesses. A review of the literature of the last 20 years did not yield any reports of an amoebic psoas abscess.- - - - - - - - - - ranking = 6keywords = abscess (Clic here for more details about this article) |

10/22. Amoebic hepatic abscesses in an hiv-positive patient.Herein we report the case of hepatic amoebic abscesses in an hiv-positive Italian seaman with a history of promiscuous heterosexual intercourse. In October 2004, the patient was hospitalized because of fever and recurring abdominal pain. Abdominal ultrasonography revealed six hepatic hypoechoid oval lesions with hyperechoid margins. Stool samples were negative for parasites and bacteria, and serology for entamoeba histolytica was also negative. Therapy with meropenem plus levofloxacin was initiated. After a partial resolution of clinical symptoms and reduction of three hepatic lesions, the patient was again hospitalized in December 2004, because of recurring intense pain at the right hypochondrium and fever. At this time, one hepatic lesion at the sixth segment was enlarged, two lesions were unchanged, and the remaining three smaller abscesses were resolved. serum antibodies for E. histolytica and amoebic antigens on the largest abscess drainage were positive; moreover, E. histolytica was also identified on drainage fluid with polymerase chain reaction (PCR). Therapy with metronidazole followed by paromomycin improved both symptoms and radiographic images. This case report suggests that in hiv-infected patients, invasive amoebiasis should be considered and atypical aspects, such as multiple hepatic lesions, delayed positivity of serology for E. histolytica, and possible bacterial superinfection should be evaluated.- - - - - - - - - - ranking = 7keywords = abscess (Clic here for more details about this article) |
