Is It Possible to Predict Sepsis, the Most Serious Complication in Prostate Biopsy?

Objective: Prostate biopsy for the diagnosis of prostate cancer by transrectal ultrasonography (TRUS) is a common procedure used in daily urology practice with a low complication rate and easy applicability. In this study, the precipitating factors and prophylaxis for sepsis, the worst complication of the procedure, were assessed. Patients and Methods: 2,023 patients with suspected prostate cancer who underwent biopsy by TRUS in one center were assessed retrospectively. The relationship between sepsis and age, serum total prostate-specific antigen (PSA) level, PSA density, prostate volume, number of biopsies, number of repeated biopsies, accompanying diagnosis of prostatitis, presence of urethral catheter, and presence of diabetes mellitus was assessed. Data were analyzed using the t test and logistic regression analysis. Results: Of the 2,023 patients, 62 (3.06%) developed sepsis within 5 days after biopsy. There was no significant relationship between the biopsy and the above parameters using the logistic regression analysis. Using the t test, it was found that the number of biopsy cores (p < 0.001), presence of urethral catheter (p < 0.0001), and presence of diabetes mellitus (p < 0.0001) were predictive factors for sepsis. Conclusion: Sepsis is a rare but life-threatening complication after prostate biopsy by TRUS. Although preoperative prophylactic oral antibiotics and enema before biopsy have proven to be effective in decreasing urinary tract infection rates, patients with urethral catheter, diabetes mellitus or those to undergo biopsy from more sites than ten cores should be closely monitored after biopsy.

The Relationships between Serum sTWEAK, FGF-23 Levels, and Carotid Atherosclerosis in Renal Transplant Patients

Background: Cardiovascular disease is the main cause of mortality after renal transplantation. Soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and fibroblast growth factor-23 (FGF-23) are two novel molecules that have been associated with atherosclerosis in different populations. In this cross-sectional study, we investigated the associations between sTWEAK, FGF-23, and carotid artery intima-media thickness (CA-IMT) in renal transplant patients. Methods: A total of 117 renal transplant patients were studied. CA-IMT was determined by B-mode Doppler ultrasonography. Serum sTWEAK and FGF-23 were measured by a commercially available enzyme-linked immunosorbent assay (ELISA). Results: Mean age was 39.6 ± 9.6 years and 51% of the patients were male. Mean sTWEAK level was 595 ± 225 pg/mL (158–1140), FGF-23 level was 92 ± 123 RU/mL (9.6–1006), and CA-IMT level was 0.62 ± 0.11 mm (0.40–0.98). sTWEAK level was positively correlated with CA-IMT. There was no association between sTWEAK and FGF-23 levels. FGF-23 was also associated with CA-IMT. In adjusted models using linear regression analysis, only age and serum TWEAK levels were predictors for CA-IMT. Conclusion: There is a positive correlation between CA-IMT and sTWEAK, but not with FGF-23 levels in renal transplant patients.

Should Subtotal Thyroidectomy Be Abandoned in Multinodular Goiter Patients From Endemic Regions Requiring Surgery

The most convenient surgical procedure for benign thyroid diseases is still controversial. The aim of this study is to determine the recurrence rate and risk factors for recurrence after different thyroidectomy procedures in multinodular goiter patients. Patients were separated into two groups according to the detection of a recurrent nodule or not after thyroidectomy. Of the 748 patients, 216 (29%) had recurrence, while 532 had no recurrent nodule. The difference between surgical procedures described as subtotal (ST), near total (NT) and total thyroidectomy (TT) was statistically significant. Transient hypoparathyroidism was significantly higher in NT and TT, when compared to ST patients (P < 0.05). Young age, bilateral multinodular goiter and insufficient surgery are risk factors affecting recurrence for benign nodular thyroid disease. Currently, subtotal procedures should be discontinued and total or near total procedures should be preferred. Meanwhile, the probability of a higher risk of hypoparathyroidism should be kept in mind.

A new insight for evaluation of the inferior turbinate with ultrasound elastography.

There are diseases that affect the stroma of the inferior turbinate and many surgical interventions that alter it. However, an objective method that can evaluate the turbinates stromal structure in detail has not been defined yet. The primary aim of this study was to investigate the effectiveness and reliability of ultrasound elastography for objective evaluation of the inferior turbinate stroma and define the most suitable elastographic technique.

A novel method for comparison of tissue fibrosis after inferior turbinate surgery: ultrasound elastography.

Background Ultrasound (US) elastography has been widely used for thyroid, liver, and lymph nodes as a research tool in the current medical practice. It has been described in the inferior turbinates and validated as a reliable, reproducible, noninvasive, and objective method that can detect the fibrosis-related tissue strain. There is no previous study that investigated the amount of fibrosis induced by radiofrequency and bipolar electrocautery in the inferior turbinates in a noninvasive and objective manner. The aim of this study was to assess the amount of inferior turbinate soft tissue fibrosis that was induced by radiofrequency ablation (RFA) and submucosal bipolar diathermy (SBD) by US elastography. Methods Thirty-eight inferior turbinates of 19 patients were included. RFA was applied to 18 inferior turbinates (group 1) and SBD was applied to 20 inferior turbinates (group 2). US elastography and visual analog scale (VAS) assessments were performed on all patients preoperatively and 6 months postoperatively. Results Preoperative mean US elastography scores in groups 1 and 2 were 2.55 ± 0.78 m/s and 2.56 ± 0.49 m/s, respectively (p < 0.05). Postoperative mean US elastography scores in groups 1 and 2 were 2.91 ± 1.03 m/s and 3.41 ± 0.86 m/s, respectively (p < 0.05). Preoperative mean VAS scores in groups 1 and 2 were 2.78 ± 0.94 and 2.50 ± 1.15, respectively. Postoperative mean VAS scores in groups 1 and 2 were 6.61 ± 1.61 and 6.10 ± 1.4, respectively (p < 0.05). Correlation of US elastography and VAS scores was insignificant (p > 0.05). Conclusion Both RFA and SBD of the inferior turbinates were effective in inducing scar tissue and, eventually, fibrosis in the soft tissue of inferior turbinates. Cauterization has been found to cause significantly higher amounts of fibrosis than radiofrequency; however, it did not reflect the comparable clinical outcome. This is the first study that objectively and noninvasively evaluates the targeted tissue fibrosis of the inferior turbinate surgeries by the novel inferior turbinate US elastography.

The associations between serum paraoxonase 1 activity and carotid atherosclerosis in renal transplant patients.

BACKGROUNDS AND AIMS Paraoxonase 1 (PON1) is a novel marker that has been shown to exert protective functions on atherosclerosis by preventing oxidative modification of serum lipoproteins. In this study, we investigated the effects of PON1 on CA-IMT in renal transplant patients. METHODS A total of 98 adult renal transplant recipients was enrolled in the study. CA-IMT was determined by B-mode Doppler ultrasonography. PON-1 activity was assessed by the rate of enzymatic hydrolysis of paraoxon to p-nitrophenol. RESULTS Mean age was 39.4 ± 9.6 years and 10% of the patients were diabetic. Time after transplant was 76 ± 59 months. Mean PON1 level was 62.1 ± 43.3 U/l. PON1 levels were negatively correlated with CA-IMT and positively with HDL cholesterol. Mean CA-IMT was 0.62 ± 0.10 mm (0.40 - 0.98). CA-IMT was positively correlated with age, male gender and negatively with proteinuria and PON1 levels. In linear regression analysis, PON1 levels were associated with CA-IMT. CONCLUSION Reduced PON1 activity is significantly associated with increased carotid atherosclerosis in renal transplant patients.

Evaluation of Inferior Turbinate Stroma with Ultrasound Elastography in Allergic Rhinitis Patients

Background: Diagnosis of allergic rhinitis is primarily based on history, physical examination and allergy testing. A technique that noninvasively evaluates the soft tissue changes in the nasal mucosa of allergic rhinitis patients has not been defined. Aims: To assess nasal mucosal changes and measure the submucosal fibrosis in allergic rhinitis patients with sonoelastography. Study Design: Case control study. Methods: Eighty-eight turbinates of 44 patients were included in the study. There were 23 prick test positive allergic rhinitis patients. The control group constituted 21 patients. The rhinitis quality of life questionnaire and the visual analogue scale were applied to the allergic rhinitis patients. A higher visual analogue scale score indicated more severe allergic rhinitis symptoms. Sonoelastographic measurements were made from the lateral nasal wall. The propagation speed of sound waves was recorded in m/s. The presence of asthma and the type of allergic rhinitis (seasonal or perennial) was noted. Results: Ten patients had seasonal allergic rhinitis and thirteen patients had perennial allergic rhinitis. Six patients (26.1%) had accompanying asthma along with allergic rhinitis. The median visual analogue scale score was 7 (3-9) in allergic rhinitis patients. The median symptom duration was 7 (1-24) months. The median quality of life questionnaire score was 3.39 (1.68-5.43) points. The median sonoelastography scores of allergic rhinitis patients and healthy subjects were 2.38 m/s (0.9-4.47) and 2.42 m/s (1.62-3.50), respectively. Sonoelastographic measurements of seasonal and perennial allergic rhinitis patients did not differ significantly (p>0.05). The presence of asthma did not have a significant impact on the elastography measurements (p>0.05). However, regression analysis revealed a significant inverse correlation (coefficients: B=0.005, standard error=0.097, beta 0=0.008) between the visual analogue scale and sonoelastography scores (p<0.05). Conclusion: Sonoelastography was not suitable as a diagnostic tool in allergic rhinitis. Reduced sonoelastography scores were measured in more symptomatic patients. Higher visual analogue scale scores could be an indicator of disease severity.
