1/10. Haemorrhagic cystitis associated with adenovirus in a patient with AIDS treated for a non-Hodgkin's lymphoma.Adenovirus-induced haemorrhagic cystitis has been reported chiefly in bone marrow or kidney transplant recipients. We report here on an hiv-positive patient treated for a Burkitt's lymphoma who developed gross haematuria associated with fever and burning urination. Usual causes of haematuria were ruled out: lithiasis, urinary tract lesions, glomerulonephritis, mycobacterium and schistosoma infections, and drug toxicity. Adenovirus was detected by cellular cultures and BK/jc virus dna sequences were detected using a polymerase chain reaction method. Because BK/JC virus shedding is very common (75%) in hiv patients receiving chemotherapy, our data strongly suggest that adenovirus was responsible for the haemorrhagic cystitis in our patient. In conclusion, adenovirus should be considered as a potential cause of haemorrhagic cystitis in AIDS patients whose immunosuppression is aggravated by cytotoxic drugs.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
2/10. Chronic cystitis caused by corynebacterium urealyticum detected by polymerase chain reaction.The case of a 73-year-old man with chronic cystitis due to corynebacterium urealyticum was complicated by hematuria and urinary stone formation. The diagnosis was based on an amplification product obtained using polymerase chain reaction for mycobacterial species on urine and a bladder biopsy specimen. A specific 212 bp amplification fragment that did not hybridize with a Mycobacterium-specific probe was recognized. sequence analysis of the fragment revealed corynebacterium urealyticum. Routine urine cultures were negative, but prolonged culture on sheep blood agar led to the isolation and identification of corynebacterium urealyticum. Identification was confirmed by polymerase chain reaction on the colonies. The patient was treated successfully with vancomycin. Integration of molecular laboratory diagnostics with conventional microbiology and pathology was synergistic for the diagnosis.- - - - - - - - - - ranking = 8keywords = bacterium (Clic here for more details about this article) |
3/10. mortality from grossly encrusted bilateral pyelitis, ureteritis, and cystitis by corynebacterium group D2.This is the first report of death due to gross encrustations of the entire upper urinary tract and bladder by corynebacterium group D2 in a man with no history of renal transplantation or prolonged catheterizations. This case demonstrates that debilitated patients with a prior endoscopic procedure are at risk for this disease process. Prolonged treatment with appropriate antibiotics, acidification of the urine, and removal of crusts is essential for proper management.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
4/10. teicoplanin treatment of alkaline encrusted cystitis due to corynebacterium group D2.Alkaline-encrusted cystitis (AEC) is a chronic inflammation of the bladder related to the gram-positive bacillus corynebacterium Group D2. This germ is often resistant to many antibiotics and is particularly difficult to eradicate in the particular setting of AEC. The authors report two observations of AEC treated with the glycopeptid antibiotic teicoplanin, which led to permanent cure of AEC.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
5/10. Emphysematous cystitis: rapid resolution of symptoms with hyperbaric treatment: a case report.INTRODUCTION: Emphysematous cystitis is a rare disease that occurs most often in elderly diabetic patients characterized by gas formation in the bladder wall due to infection. The infecting organism is usually an aerobic bacterium, most commonly E. coli although anaerobic species have also been reported. We report the use of hyperbaric oxygen in a patient with emphysematous cystitis and air in the femoral vein in which the treatment rapidly resolved the symptoms and radiological abnormalities. methods: A 65-year-old female presented to the Emergency Department with altered mental status, weakness, dark urine, dysuria and fever. She was febrile and lethargic. Abdominal exam showed suprapubic tenderness. urinalysis was positive for white blood cells and bacteria. A CT scan of the abdomen demonstrated extensive air in the bladder wall with an air bubble in the femoral vein. Presumptive diagnosis was urinary tract infection, emphysematous cystitis, and sepsis. A question of air embolism was raised due to the intravascular gas. The patient was treated with hyperbaric oxygen (2.85 atm abs, 90 minutes) on two separate occasions in the first 12 hours. Within 24 hours, the patient's condition rapidly improved. Repeat CT scan 48 hours after admission showed near complete resolution of the emphysematous cystitis. The patient grew klebsiella pneumonia from her urine. CONCLUSIONS: Emphysematous cystitis is a rare condition caused by either aerobic or anaerobic bacteria and may be associated with both bladder wall and intravascular gas formation. Hyperbaric oxygen therapy has not been previously reported as a treatment modality. The rapid improvement in our patient may indicate a role for hyperbaric oxygen in addition to IV hydration and antibiotics in this disease.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
6/10. Encrusted cystitis in an immunocompromised patient: possible coinfection by corynebacterium urealyticum and E. coli.Encrusted cystitis is a severe chronic inflammatory disease of the bladder characterized by excessively alkaline urine and calcifications within the bladder wall. A case of a 60 year-old man affected by systemic lupus erythematosus (SLE), which developed encrusted cystitis due to corynebacterium urealyticum with E. coli co-infection, shows that the treatment of encrusted cystitis with a endoscopic debulking of the encrusted stones and an antimicrobial therapy specific for C. urealyticum often is not sufficient for the complete resolution of symptoms.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
7/10. urinary tract infection caused by corynebacterium group D2: report of 82 cases and review.corynebacterium group D2 (CGD2) is a slow-growing, urea-splitting, multiantibiotic-resistant microorganism that is frequently isolated from urine samples and that, in certain circumstances, produces infection of the lower urinary tract (acute and chronic cystitis) and the upper urinary tract (pyelonephritis). This paper analyzes (by means of a retrospective and partially prospective clinical protocol) our experience with 82 patients with CGD2 bacteriuria. The infection was symptomatic in 62% of cases, and the clinical diagnoses included acute and chronic cystitis and pyelonephritis with or without bacteremia. Because CGD2 infection of the urinary tract may require specific antimicrobial treatment and because CGD2 is a fastidious microorganism, we recommend prolonged incubation of urine cultures (up to 48-72 hours), especially if the routine culture is negative, when patients are symptomatic, have alkaline urine, or have struvite crystals in the urine sediment.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
8/10. corynebacterium-induced cystitis with mucosal incrustations.Alkaline-incrusted cystitis is a rare condition that was first described more than 70 years ago. Since then few cases have been reported. To our knowledge, we report the second such case in the literature in which corynebacterium D2 was considered as the causative factor of incrusted cystitis.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
9/10. Late recurrence of mycobacterium bovis genitourinary tuberculosis: case report and review of literature.A patient is described in whom mycobacterium bovis genitourinary tuberculosis occurred initially 25 years after childhood scrofula and then recurred 29 years later despite apparently successful therapy. A review of the literature indicated that this 29-year interval between successive bouts of clinical genitourinary tuberculosis is among the longest described. This case also is a reminder that, although rare, mycobacterium bovis infection and genitourinary tuberculosis still occur. To avoid nonrecognition of this disease and its potentially serious consequences, clinicians should remain vigilant for tuberculosis even in unusual clinical circumstances.- - - - - - - - - - ranking = 6keywords = bacterium (Clic here for more details about this article) |
10/10. prevalence of corynebacterium urealyticum in urine specimens collected at a university-affiliated medical center.corynebacterium urealyticum (formerly corynebacterium group D2) has been implicated as a cause of alkaline-encrusted cystitis and urinary tract struvite calculi. Despite preselecting urine specimens with neutral and alkaline pHs and using prolonged incubation on a selective medium, isolation of this organism was rarely observed in a population of hospitalized patients. We do not recommend routine cultures for this organism unless the urine is alkaline and struvite crystals, leukocytes, and erythrocytes are present.- - - - - - - - - - ranking = 6keywords = bacterium (Clic here for more details about this article) |
