1/7. Mycotic aneurysm of the ascending aorta following CABG.Mycotic aneurysm of the thoracic aorta is a rare and life threatening condition. Two patients are presented (both male, aged 66 and 59 years) in whom coronary artery bypass surgery was complicated by the development of a mycotic aneurysm. Fever preceded the radiological and echocardiographic signs of the aneurysm by at least several months in both cases. blood cultures were negative for one patient and the source of corynebacterium sp infection in the other was not determined for several months. Both patients died before surgery could correct the aneurysm.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
2/7. Tuberculous gumma (cutaneous metastatic tuberculous abscess) with underlying lymphoma.Cutaneous tuberculosis is an infrequent first sign of disseminated tuberculosis. We describe a patient with 2 cutaneous ulcerations that grew mycobacterium tuberculosis. Despite an initial response to antimycobacterial therapy, the fever relapsed. After several months, biopsy of a single cervical lymph node showed a T cell-rich B cell lymphoma. Our patient had metastatic tuberculous abscesses (tuberculous gummas), which are secondary to disseminated tuberculosis, and an underlying occult lymphoma, both believed to be sequentially presenting as a fever of unknown origin.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
3/7. 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 = bacterium (Clic here for more details about this article) |
4/7. Cervico-mediastinal tuberculous lymphadenitis presenting as prolonged fever of unknown origin.Prolonged fever of unknown origin (FUO) is a challenging and important medical problem. Tuberculosis is the most frequent cause of FUO, especially in endemic regions, such as developing countries. We present a case of cervico-mediastinal tuberculous lymphadenitis that had been searched and followed up as a prolonged FUO. Especially in endemic areas, tuberculosis should be borne in mind in the differential diagnosis of FUO cases with granulomatous lymphadenitis presenting as prolonged or recurrent fever, even if the cultures and polymerase chain reaction for mycobacterium tuberculosis are negative.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
5/7. Laparoscopic intervention in resistant hepatosplenic tuberculosis presenting as pyrexia of unknown origin.Hepatosplenic tuberculosis (HST), rarely encountered in surgical practice, is seen in-patients with disseminated tuberculosis. A 20-year-old female presenting with pyrexia of unknown origin (PUO) was subsequently diagnosed to have lymph-nodal tuberculosis with involvement of liver and spleen. Despite anti-tuberculosis treatment (ATT) for 3 months, clinical improvement did not occur and fever persisted. Laparoscopic splenectomy and drainage of the hepatic cold abscess were done with favorable results. Smear for acid fast bacilli (AFB), culture for mycobacterium tuberculosis and histopathological examination (HPE) established the diagnosis of tuberculosis (TB).- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
6/7. Cryptogenic hepatic abscess in two uncompromised children.A pre-mortem diagnosis of cryptogenic liver abscess in children is rare, but this diagnosis must be considered in the evaluation for pyrexia of unknown origin. Two previously healthy children were suspected of harboring liver abscesses. Radioisotopic, sonographic, and angiographic evidence supported the clinical diagnosis. Operative drainage was performed in each case. No source for either abscess was found and no cause established. Anaerobic bacteria, microaerophilic streptococcus and fusobacterium necrophorum, each in pure culture, were retrieved on culture of the pus from each child's abscess. Experience gleaned from these two cases emphasizes the possibility of an hepatic abscess existing in the uncompromised child with fever of unknown origin. A cryptogenic hepatic abscess may occur in a child with only mild gastrointestinal complaints and in a child with sickle cell disease. Recovery is attributed to suspicion of diagnosis, prompt investigation, operative drainage, effective culture technique with isolation of organism and appropriate antibiotic coverage.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
7/7. Unilateral adrenal mass due to mycobacterium kansasii in an AIDS patient.Infection with mycobacterium kansasii in patients with acquired immunodeficiency syndrome usually involves the lung or disseminated infection. We report a case of infection with M kansasii confined to the adrenal gland and possibly to an adjacent vertebral body that presented as a fever of undetermined origin.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
