Single donor-derived strongyloidiasis in three solid organ transplant recipients: case series and review of the literature.

Donor-derived Strongyloides stercoralis infections in transplant recipients are a rare but recognized complication. In this case series, we report donor-derived allograft transmission of Strongyloides in three solid organ transplant recipients. Following detection of infection in heart and kidney-pancreas recipients at two different transplant centers, a third recipient from the same donor was identified and diagnosed. S. stercoralis larvae were detected in duodenal aspirates, bronchial washings, cerebrospinal fluid, urine and stool specimens. Treatment with ivermectin and albendazole was successful in two of the three patients identified. The Centers for Disease Control and Prevention was contacted and performed an epidemiologic investigation. Donor serology was strongly positive for S. stercoralis antibodies on retrospective testing while all pretransplant recipient serum was negative. There should be a high index of suspicion for parasitic infection in transplant recipients and donors from endemic regions of the world. This case series underscores the need for expanded transplant screening protocols for Strongyloides. Positive serologic or stool tests should prompt early treatment or prophylaxis in donors and recipients as well as timely notification of organ procurement organizations and transplant centers.

Predicting no-reflow phenomenon prior to primary percutaneous coronary intervention using a novel probability risk score derived from clinical and angiographic parameters.

OBJECTIVE: We aimed to create a clinically usable probability risk score for prediction of no-reflow (NRF) phenomenon prior to primary percutaneous coronary intervention (PPCI). PATIENTS AND METHODS: This single-center and retrospective study included 1254 patients with acute ST-segment elevation myocardial infarction (STEMI) who underwent PPCI. Patients were randomly assigned into two groups in the ratio 2:1, the derivation dataset (n=840) and validation dataset (n=414). Independent predictors of NRF were identified and combined to create a prediction model using univariate and multivariate regression analysis in the derivation dataset. The risk score was tested and validated by calculating area under the receiver operating characteristic (ROC) curves in the derivation and validation datasets, respectively. RESULTS: Five significant, independent predictors of NRF were identified: age ≥ 65 years (odds ratio [OR]: 2.473, 95% confidence interval [CI]: 0.389-1.484, p < 0.01), heart rate ≥ 89 bpm (odds ratio [OR]: 1.622, 95% confidence interval [CI]: 0.024-0.945, p < 0.05), Killip class ≥ II (odds ratio [OR]: 1.914, 95% confidence interval [CI]: 0.024-1.306, p < 0.01), total ischemic time ≥ 268 min (odds ratio [OR]: 2.652, 95% confidence interval [CI]: 0.493-1.565, p < 0.01), and thrombus burden G≥4 (odds ratio [OR]: 8.351, 95% confidence interval [CI]: 0.344-15.901, p < 0.01). The risk score was created combining these predictors with assigned points. The overall score ranged from 0 to 17 points. The optimal cutoff value of the risk score was 11 points (area under curve [AUC]: 0.772, 95% confidence interval [CI]: 0.729-0.815, sensitivity 71.21%, specificity 70.34%, positive predictive value 30.92%, negative predictive value 92.91%, p < 0.001). The ROC curve for the validation group showed good discriminant power. CONCLUSIONS: We developed a novel risk score based on five clinical and angiographic parameters, which might be a useful clinical tool for prediction of NRF in STEMI patients prior to PPCI with an acceptable accuracy.

[Five-years experience with urinary derivation by Sygma-Rectum pouch at the department for urology in Smederevo]. / Petogodisnje iskustvo uroloske sluzbe u Smederevu sa urinarnom derivacijom sygma-rectum pouch.

Bladder cancer has poor prognosis. Outcome of the treated patients is dependent on correct staging, histologic grade of the tumor, and correctly realized surgical intervention, i.e. radicality of the operation. During the period from 2002. to 2004, on the Department for Urology in Smederevo, 120 patients were surgically treated because of bladder tumors. Of that number, in 34 patients radical cystectomy and derivation by Sygma-Rectum pouch was done. Of these 34 patients, 22 (64.7%) were being followed during the five-years period.

Radical retropubic prostatectomy--results in 127 surgically treated patients.

Radical prostatectomy represents an optimal therapeutic method in treatment of the localized prostatic carcinoma. It may be performed using retropubic, perineal, transcoccygeal or laparoscopic approach. In a multicenter study, the authors have analyzed 127 patients surgically treated in the period 1992 - 2003. All the patients were preoperatively diagnosed with the localized prostatic carcinoma. The patients were operated at the Clinic of Urology in Belgrade (92 patients) and other departments of urology in Serbia (35 patients). The youngest patient was 49 while the oldest one was 75 (mean age 64 years). The surgical procedure duration ranged between 60 and 120 minutes. Over the last five years, the need for blood transfusion was below 50%. All the patients underwent retropubic radical prostatectomy.
