1/29. Relapsing Henoch-Schonlein purpura associated with pseudomonas aeruginosa pyelonephritis.Henoch-Schonlein purpura is a systemic vasculitis of unknown cause. It is frequently triggered by a streptococcal upper respiratory tract infection. Other bacteria have been implicated as triggering agents. We report a recurring case of Henoch-Schonlein purpura in a patient with Pseudomonas pyelonephritis. The Henoch-Schonlein purpura remitted only when the infection was eradicated. Pseudomonas infection should be added to the list of bacteria that can trigger Henoch-Schonlein purpura.- - - - - - - - - - ranking = 1keywords = tract infection, tract, upper (Clic here for more details about this article) |

3/29. A rational approach to urinary tract infections in older patients.urinary tract infections (UTIs) occur more commonly in the elderly than in younger adults. The frequency of concomitant chronic illness and decreased resistance in this age group confers increased rates of morbidity and mortality, and manifestations are often atypical. diagnosis requires careful interpretation of urine culture results and a determination of the infection as asymptomatic bacteriuria, uncomplicated UTI, or complicated UTI. This, in turn, guides therapeutic measures, including the use of oral antibiotics.- - - - - - - - - - ranking = 4.9999863633375keywords = tract infection, tract (Clic here for more details about this article) |
4/29. Acute renal failure in adults with uncomplicated acute pyelonephritis: case reports and review.Acute renal failure is a rare complication of acute pyelonephritis in patients who do not have urinary obstruction. Although urinary tract infections are common in adults, pyelonephritis is rarely considered in the differential diagnosis of acute renal failure nor is renal failure considered a likely consequence of bacteriuria. In this review, the cases of acute renal failure caused by acute pyelonephritis that have been reported in the last quarter century are examined. Including two new cases reported, only 12 cases of acute pyelonephritis resulting in acute renal failure were found. Three of these occurred in patients with a solitary kidney. All cases occurred in individuals who had no history of urinary tract infections, and all were caused by escherichia coli. In several cases, the administration of non-steroidal antiinflammatory drugs contributed to disease. Three cases occurred after catheter-acquired bacteriuria. Acute renal failure is an uncommon but serious consequence of uncomplicated acute pyelonephritis in adults.- - - - - - - - - - ranking = 1.999994545335keywords = tract infection, tract (Clic here for more details about this article) |
5/29. Puerperal group A streptococcus infection: a case report.BACKGROUND: Group A streptococcus (GAS) sepsis is a rare event but carries a high risk of maternal mortality. CASE: A case of puerperal infection occurred with GAS. This patient had had an uneventful prenatal and intrapartum course. She was noted to have high, spiking fevers immediately postpartum, with minimal clinical symptoms. Her blood cultures were positive for GAS, most likely from a urinary tract infection. She was started on broad-coverage antibiotics and defervesced on postpartum day 4. She remained afebrile and was discharged on postpartum day 8. CONCLUSION: patients with puerperal GAS sepsis commonly appear well clinically, with minor somatic complaints. GAS bacteremia should be suspected and promptly treated in women with high, spiking fevers early in the postpartum period. There are currently no guidelines on preventing vertical transmission. It is unclear how a patient with a previous history of GAS should be managed. Prophylactic use of penicillin during future labor may be warranted.- - - - - - - - - - ranking = 0.99999727266749keywords = tract infection, tract (Clic here for more details about this article) |
6/29. Functional urinary outlet obstruction causing urosepsis in a male multiple sclerosis patient.Detrusor-external sphincter dyssynergia (DESD) is a neuropathic disorder of micturition that exists when the simultaneous contractions of the detrusor muscle and external urethral sphincter oppose each other. When the external urethral sphincter contracts during a detrusor contraction, functional urinary outflow obstruction occurs by the increased urethral resistance. This loss of coordination between the bladder and its outlet is associated with a high risk for serious urologic complications, such as vesicoureteral reflux, hydronephrosis, and urosepsis. This report describes a male multiple sclerosis patient with DESD who developed functional outlet obstruction with urosepsis and discusses the diagnosis and treatment of this potentially life-threatening voiding dysfunction.- - - - - - - - - - ranking = 0.014500388462741keywords = tract (Clic here for more details about this article) |
7/29. 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 = 4.0144922064652keywords = tract infection, tract, upper (Clic here for more details about this article) |
8/29. gardnerella vaginalis in infections of the urinary tract.During a period of 6 months, urine from 3576 patients was cultured for gardnerella vaginalis. Specimens from 32 patients yielded this species. Eleven (0.3%) of the isolates were judged to be of clinical importance. Seven were from women and four from men. Two of these patients, both women, suffered from spontaneous cystitis. Hence G. vaginalis is very unusual as a primary pathogen in the urinary tract. More often it may cause infections related to urological abnormalities or as a complication of urological procedures. Two of the men in our series had chronic prostatitis, one an infected urinoma. All six remaining patients had either undergone a urological procedure or had had an indwelling urethral catheter for more than 6 hours. A selective medium for G. vaginalis is recommended for screening cultures before urological procedures and when this species is suspected on microscopy. The role of metronidazole in extravaginal infections is discussed and the use of an antibiotic more active against G. vaginalis is recommended.- - - - - - - - - - ranking = 0.024167314104568keywords = tract (Clic here for more details about this article) |

10/29. urinary tract infections in urology: a urologist's view of chronic bacteriuria.urine culture performed during and after antimicrobial therapy will differentiate unresolved urinary tract infections from recurrent infections. Recurrent infections with the same organism and at close intervals are frequently caused by a focus of bacterial persistence within the urinary tract, and infections with different organisms and/or at longer intervals are characteristic of reinfections with bacteria from outside the urinary tract. Unresolved infections are usually due to resistant bacteria and are treated by modification of therapy based on antimicrobial sensitivity testing. When unresolved bacteriuria is caused by organisms sensitive to the initial antimicrobial therapy, azotemia or a large bacterial mass density should be suspected. Recurrent infections at close intervals and/or with the same organism are usually caused by a bacterial focus in an acquired or congenital abnormality of the urinary tract such as infection stones, which must be removed to cure the recurrent infections. If the bacterial focus within the urinary tract cannot be removed, long-term low-dose antimicrobial prophylaxis can prevent the morbidity of recurrent infections. Reinfection requires careful bacteriologic monitoring and low-dose prophylactic, intermittent, or post-intercourse antimicrobial therapy.- - - - - - - - - - ranking = 5.0193202146211keywords = tract infection, tract (Clic here for more details about this article) |
