Renal Cell Carcinoma of the Kidney with Synchronous Ipsilateral Transitional Cell Carcinoma of the Renal Pelvis

A 73-year-old man was admitted to our clinic with flank pain and gross macroscopic hematuria. Radiologic examination revealed a solid mass in the left kidney and additionally another mass in the ureteropelvic junction of the same kidney with severe hydronephrosis. Left nephroureterectomy with bladder cuff removel was performed, and histopathological evolution showed a Fuhrman grade 3 clear cell type RCC with low-grade TCC of the pelvis

The effect of Sertraline, Paroxetine, Fluoxetine and Escitalopram on testicular tissue and oxidative stress parameters in rats

Introduction: The aim of this study was to evaluate the effect of selective serotonin reuptake inhibitors (SSRIs) on testicular tissue and serum malondialdehyde (MDA) levels in rats. Materials and methods: A total of 40 male Wistar albino rats, 5.5-6 months old, were equally divided at random into five groups: group 1 was the control group, group 2 received sertraline 10mg/kg (p.o), group 3 was administered fluoxetine 10mg/kg (p.o), group 4 received escitalopram 10mg/kg (p.o), and group 5 (n = 8) was administered paroxetine 20mg/kg. Each dose was administered orally for two months. Johnsen&#8217;s criteria were used to categorize spermatogenesis. Johnsen&#8217;s method assigns a score of 1 to 10 to each tubule cross-section examined. In this system, a Johnsen score of 9 and 10 indicates normal histology. Serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels were evaluated. Serum MDA levels were also measured. Results: The mean Johnsen scores were 9.36 &#177; 0.33, 9.29 &#177; 0.32, 8.86 &#177; 0.48, 9.10 &#177; 0.56, and 8.33 &#177; 0.90 in control group, sertraline group, fluoxetine group, escitalopram group, and paroxetine group, respectively. The Johnsen score was significantly lower for paroxetine group compared with the control group (p < 0.05). The mean FSH level increased only in the sertraline group. With the exception of the fluoxetine group, the testosterone levels were lower in all groups compared with the control group. The total testosterone level was significantly lower in the sertraline group compared with the control group [40.87 (22.37-46.8) vs. 15.87 (13.53-19.88), p < 0.01]. There were no significant differences between the groups with respect to the MDA and LH levels (p = 0.090 and p = 0.092). Conclusion: These data suggest that SSRIs have a negative effect on testicular tissues. This negative impact is markedly greater in the paroxetine group. To determine the exact mechanism of action of these drugs on testicular tissue, well-designed randomized controlled clinical studies are needed on a larger population

The effects of oxytocin on penile tissues in experimental priapism model in rats

WOS: 000459537700007PubMed ID: 30515737PurposeThis study aimed to demonstrate the effects of oxytocin on penile tissues in ischemia-reperfusion injury developed after priapism.MethodsForty Wistar Albino strain male rats were divided into four groups. The control group (n=10) was not intervened. In Group 2, a rat model of priapism was constructed and maintained for 1 h. In Group 3, reperfusion was ensured for 30min following priapism. Rats in Group 4 rats were given oxytocin 30min before the induction of reperfusion following priapism. All rats were penectomized, and adequate amounts of blood sample were drawn. Inflammation, vasocongestion, desquamation, and edema in penile tissue were scored between 0 and 3 points (0: normal, 1: mild, 2: moderate, 3: severe) to evaluate the severity of tissue damage. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and the levels of malondialdehyde (MDA), and nitric oxide (NO) in blood samples were determined spectrophotometrically.ResultsIn histopathological examination, statistically significant positive changes were detected in vasocongestion, inflammation, desquamation, and edema scores in Group 4 than in Group 2 and Group 3 (p0.05).ConclusionsOxytocin protected against priapism-induced ischemia-reperfusion injury developed in cavernosal tissue as observed based on histopathological and biochemical evidence. Although this is an experimental study, oxytocin can be thought as an alternative drug in the treatment of priapism
