PURPOSE: Many patients admitted for acute myocardial infarction (AMI) have chronic renal insufficiency and erectile dysfunction (ED). This study aimed to evaluate the relationship between ED and the glomerular filtration rate (GFR) in patients with coronary artery disease. MATERIALS AND METHODS: We studied 183 patients undergoing coronary angiography owing to AMI. The GFR was calculated and the International Index of Erectile Function-5 (IIEF-5) was used to evaluate ED. The relations between erectile function, GFR, and the number of occluded coronary arteries were evaluated. RESULTS: Of 183 patients with a mean age of 55.2+/-11.16 years who underwent coronary angiography owing to AMI, 100 (54.64%) had ED. The ED rate was 45.36% (44/97) in patients with single-vessel disease, 64.5% (31/48) in patients with two-vessel disease, and 65.7% (25/38) in patients with three-vessel disease. The ED rate in patients with single-vessel disease was significantly lower than in the other groups (p<0.001). The mean IIEF scores were 24.2+/-4.3, 20.4+/-4.9, and 20.5+/-4.2 in the three groups, respectively (p<0.001). Mean GFRs were similar in patients with single-vessel disease, two-vessel disease, and three-vessel disease (128.2+/-46.8, 130.8+/-70.9, and 110.8+/-44.6, respectively, p=0.171). The GFR was significantly lower in the presence of ED only for single-vessel disease (p=0.001). CONCLUSIONS: This study confirmed that the presence and severity of ED are linked to the number of occluded vessels as documented by coronary angiography. The presence of ED and reduced GFR are associated with single-vessel coronary artery disease. This relationship can be used to predict the likelihood of coronary artery disease.

PURPOSE: Even though hypospadias is one of the most common congenital anomalies, the cause of hypospadias is largely unknown. With regard to molecular biology and microarray technology, it appears that hypospadias is potentially related to disrupted gene expression. Genomic analysis of hypospadiac tissue indicated a potential role for activating transcription factor 3 (ATF3) in the development of this anomaly. This study prospectively examined the expression of ATF3 in tissues from 20 children with hypospadias compared with 26 normal penile skin tissue samples from elective circumcision. MATERIALS AND METHODS: Prepucial tissue was obtained from children who underwent repair of hypospadias for comparison with tissue samples from children who underwent elective circumcision. Skin specimens were evaluated for the expression of ATF3 protein by immunohistochemical staining. RESULTS: Immunohistochemical staining for ATF3 in samples from children who underwent repair of hypospadias was significantly greater than in samples from children who underwent elective circumcision (80% vs. 11%, respectively; p<0.05). CONCLUSIONS: Our results indicate that ATF3 is up-regulated in the penile skin tissue of boys with hypospadias, which suggests a role for this transcription factor in the development of this abnormality.

Purpose:
Three intravesical treatment agents were compared in an interstitial cystitis rat model: chondroitin sulfate, hyaluronic acid, and combined hyaluronic acid-chondroitin sulfate.
Methods:
Thirty-five female rats were divided into 5 groups: control (group I), isotonic (group II), chondroitin sulfate (group III), hyaluronic acid (group IV), and hyaluronic acid-chondroitin sulfate (group V). Chemical cystitis was induced in all experimental groups by intravesical instillation of 1 mL of hydrogen peroxide (H2O2) for 15 minutes via the transurethral route. The treatment was administered every other day for 3 sessions 2 days after inducing chemical cystitis. Groups II, III, IV, and V received 1 mL of 0.9% NaCl, 1 mL of 0.2% sodium chondroitin sulfate, 1 mL of low-molecular-weight hyaluronic acid, and 1 mL of 2% sodium chondroitin sulfate+1.6% sodium hyaluronic acid, respectively. On day 7, the animals were sacrificed and the bladders were removed for histopathological and immunohistochemical assessments.
Results:
Significant between-group differences were found in vascular congestion (P=0.006). The grade of submucosal edema in groups II and IV was significantly higher than in group I (P=0.006, P=0.006, respectively). In group I, the grade of granulation tissue was lower than the other 4 groups, but no significant difference was found between the remaining groups (P=0.016). Neutrophil cell infiltration was more intense in groups II and IV than in group I (P=0.006, P=0.006, respectively). Significant differences in the leukocyte and mast cell count were detected between groups II and IV (P<0.001, P<0.001, respectively). Abnormal zonula occludens-1 and uroplakin-III immunoreactivity in group II was higher than in groups I, III, or V (P=0.002, P=0.010, respectively). Interleukin-8 expression was lower in group V than in group II (P=0.001).
Conclusion
A single treatment of chondroitin sulfate and combined hyaluronic acid-chondroitin sulfate treatment demonstrated efficacy by suppressing inflammation and achieving improvements in the urothelium.
