Combined Bladder, Urethral and Uterine Rupture After a Normal, Spontaneous Vaginal Delivery at Home - a Case Report
(Sci Printers & Publ inc, 2005) Zeteroglu, S; Bayrakli, H; Yilmaz, Y; Sahin, HG
BACKGROUND: Uterine rupture and associated injury to the maternal bladder and urethra have been rarely reported. All those cases were associated with a scarred uterus or augmentation of labor. We report a case of simultaneous bladder, urethral and uterine rupture in an unscarred uterus following delivery at home. CASE: A 22-year-old woman was referred front a peripheral hospital to the emergency unit of the Medical Faculty, Yuzuncu Yil University, after delivering at home. On vaginal examination, the bladder neck and proximal one third of the urethra were ruptured. Intraoperatively it appeared that the posterior wall of the bladder and bladder base had ruptured and separated from the level of the interureteric ridge. An extensive rupture of the lower uterine segment to the left sidewall of the uterus was seen. CONCLUSION: To prevent these complications, uneducated, traditional birth attendants should be replaced by at least midwives, and the rate Of unsupervised home delivery should be reduced.
Diagnostic Value of Cytokeratin-18 as a Tumor Marker in Bladder Cancer
(Pergamon-elsevier Science Ltd, 2002) Sekeroglu, MR; Aydin, S; Dülger, H; Yilmaz, Y; Bayrakli, H; Noyan, T
Objectives: The aim of the study was to compare serum levels of cytokeratin-18 of patients with bladder cancer with those of the healthy controls, and to investigate the relation between cytokeratin level and the tumor stage. Design and methods: Serum cytokeratin-18 levels of 38 patients with bladder cancer and of 25 healthy people were determined. Tumor stage was T-1 in 12 patients, T-2 in 9 patients, T-3 in 10 patients and T-4 in 7 patients. The serum cytokeratin-18 levels in these cases were analyzed with respect to the stage of the tumor. Results: Cytokeratin- 18 level in the patient group was found to be significantly higher than that of the control group (p < 0.010) when the groups were totally compared. However, when the levels in patients with different tumor stages were compared with that of the controls, the difference was not significant in patients with stage I and 2 tumors (p > 0.05). Regarding the cut off value as 4.0 ng/mL, sensitivity and specificity for serum cytokeratin-18 were found to be 53% and 72% respectively. When sensitivity was calculated with respect to tumor stages, it was 8% for T-1, 33% for T-2, 90% for T-3 and 100% for T-4. On the other hand, considering higher stage (T-3 and T-4) tumors only, the sensitivity was calculated as 94%, but the sensitivity for lower stage (T-1 and T-2) tumors was 19%. Conclusions: It is clear that serum cytokeratin- 18 level increases in patients with bladder cancer. However, it can only be useful as a tumor marker in the diagnosis of T-3 and higher staged tumors. This study indicated that cytokeratin- 18 does not have any diagnostic value in lower stage bladder cancers. (C) 2002 The Canadian Society of Clinical Chemists. All rights reserved.
Effects of Sildenafil Citrate, Acetylcholine. and Sodium Nitroprusside on the Relaxation of Rabbit Cavernosal Tissue in Vitro
(Elsevier Science inc, 2001) Aydin, S; Özbek, H; Yilmaz, Y; Atilla, MK; Bayrakli, H; Çetin, H
Objectives. To investigate the effect of sildenafil together with the influence of sodium nitroprusside and acetylcholine and further discuss its mechanism of action in vitro. Methods, Isolated strips of rabbit corpus cavernosum were stimulated isometrically with phenylephrine. Graded relaxations were induced using increasing concentrations of acetylcholine, sodium nitroprusside, and sildenafil alone and in combination. Results, The agents all relaxed the rabbit corpus cavernosal strips in a dose-dependent manner. The inhibitory potentials of the test agents were ranked (from least inhibitory to most inhibitory) as follows: sildenafil, acetylcholine plus sildenafil, sodium nitroprusside, sodium nitroprusside plus sildenafil, acetylcholine. The presence of sodium nitroprusside in the medium reduced the median effective dose for the sildenafil-induced relaxation of the cavernosal tissue from 3.65 x 10(-5) M to 2.73 x 10(-7) M, and the presence of acetylcholine reduced it to 9.79 x 10(-6) M. Conclusions. Sildenafil enhances the relaxing effect of both sodium nitroprusside and acetylcholine on the phenylephrine-induced contraction of rabbit cavernosal tissue. UROLOGY 58: 119-124, 2001.

Nasal Obstruction as a Common Side-Effect of Sildenafil Citrate
(Tohoku Univ Medical Press, 2006) Kiroglu, AF; Bayrakli, H; Yuca, K; Cankaya, H; Kiris, M
Sildenafil citrate is an effective oral drug for erectile dysfunction. The main action of sildenafil is the enhancement of the effect of nitric oxide (NO) by inhibiting the cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase-5 (PDE-5). an enzyme responsible for degradation of cGMP. NO is also present in the nasal mucosa and is responsible for vasodilation causing congestion and nasal obstruction. The aim of this study was to detect the effect of sildenafil on nasal mucosa in terms of nasal obstruction. A total of 16 patients presented to urology clinic suffering from impotence and medicated with sildenafil were included in the study. Before and after oral administration of 50 mg sildenafil, in all of the patients the nasal patency was examined by active anterior rhinomanometry (a method of assessing nasal resistance) using air pressure of 150 Pascal. In addition, all patients were asked about their sensation of nasal patency to detect the symptomatic nasal obstruction. There was a significant decrease in nasal air flow values (cm(3)/s) (p < 0.05). Except for three cases, all patients indicated that they had the sensation of nasal obstruction after the use of sildenafil (p < 0.05). Nasal obstruction is a common complaint for the patients using Sildenafil.
