Effect of administration mode (patient vs physician) and patient's educational level on the Turkish version of the International Prostate Symptom Score.

OBJECTIVES: To compare the effectiveness of the International Prostate Symptom Score (IPSS) when administered by the physician to when self-administered by the patient. The effect of the patient's educational level on the IPSS was also evaluated. METHODS: One hundred and seven previously untreated patients with symptomatic benign prostatic hyperplasia (BPH) completed the Turkish version of the International Prostate Symptom Score (Turkish I-PSS) and quality of life (QOL) questionnaires during a single office visit, first on their own and then with an interviewing physician. The patients were categorized into three groups according to their educational levels. Paired t-tests were performed to compare the total IPSS (tIPSS) and QOL results between the two testing modes. IPSS and QOL scores resulting from both modes were compared using a kappa test. Differences between the physician-assisted and self-administered scores among the different educational groups were further compared using a one-way anova test and Post Hoc Multiple Comparisons. To compare the objective effectiveness of tIPSS and QOL between the two testing modes, we selected the positive actual state, which was maximum urine flow (Qmax) of 15 mL/s or less and constructed receiver operating characteristics (ROC) curves for all patients. This estimation was constructed for each educational level. RESULTS: There were no statistical differences in IPSS and QOL values obtained by the patients or physicians (P > 0.05). The ROC areas for tIPSS were 0.94 and 0.93, and the ROC areas for QOL scores were 0.97 and 0.91 for information obtained by physicians and patients, respectively. When IPSS answers and QOL scores were evaluated separately, consistency was found across both modes of administration. However, there were lower levels of consistency in answers to IPSS questions 2, 5 and 6 (P = 0.59;0.42; 0.52, respectively). There was no significant difference among the aforementioned data in the educational groups. CONCLUSION: Although the total IPSS and QOL scores were not affected by the different modes of administration, we recommend that the physicians should evaluate answers to questions 2, 5 and 6 carefully. The present study demonstrates that the educational level did not affect the IPSS and QOL when administered either by the physician or the patient.

Diagnosis of pediatric varicoceles by physical examination and ultrasonography and measurement of the testicular volume: using the prader orchidometer versus ultrasonography.

INTRODUCTION: The differentiation of unilateral versus bilateral varicoceles and testicular volume measurements are important in determining the need for adolescent varicocele surgery and also in following patients after varicocelectomy. The aim of this study was to prospectively compare the findings of physical examination and color Doppler ultrasonography in the diagnosis of pediatric varicoceles and to compare the findings using the Prader orchidometer and scrotal ultrasonography in the measurement of testicular volumes. PATIENTS AND METHODS: This study included 68 boys with varicoceles, ranging in age from 8 to 19 years. Varicoceles were diagnosed using both physical examination and scrotal color Doppler ultrasonography. The testicular volumes of 136 testicles were measured using the Prader orchidometer and scrotal ultrasonography. A difference of more than 10% or 2 ml in each testicular volume was considered significant. RESULTS: The mean age of the boys was 13.5 +/- 2.3 years. On physical examination, a left unilateral varicocele was diagnosed in 46 boys (67.6%). The other 22 boys (32.4%) had bilateral varicoceles. Color Doppler ultrasonography detected bilateral varicoceles in 4 of the 46 boys (8.7%) who were diagnosed by physical examination as having only left unilateral varicoceles (grade 3 in 3 patients and grade 2 in 1 patient). A different of more than 10% or 2 ml in testicular volume using the Prader orchidometer versus scrotal ultrasonography was detected in 3 out of 136 testicles (2.2%). The correlation between ultrasonography and Prader orchidometer results in the measurement of testicular volumes was statistically highly significantly consistent using the intraclass correlation test (r = 0.997 and p < 0.001 for the left testis; r = 0.998 and p < 0.001 for the right testis). CONCLUSIONS: Although the management of subclinical varicoceles remains controversial, these data show that color Doppler ultrasonography may be necessary in the diagnosis of bilateral varicoceles, especially in boys with high-grade left varicoceles. In contrast, scrotal ultrasonography, if considered the gold standard, did not show superiority over the Prader orchidometer in measuring testicular volumes.

Effect of fexofenadine, a mast cell blocker, in infertile men with significantly increased testicular mast cells.

AIM: To investigate the role of fexofenadine, a mast cell blocker, on semen quality in the treatment of infertile men. METHODS: The study included 16 Turkish idiopathic infertile men with azoospermia or oligozoospermia who underwent testicular biopsy to examine mast cells containing tryptase. In all patients, a complete medical history, clinical examination, semen analysis and serum hormone assay were carried out. The biopsy specimens were immunohistochemically stained with antihuman tryptase for mast cells. The number of total mast cells per seminiferous tubule was calculated and recorded as mast cell index. The patients were divided into two groups according to their mast cell index: the higher (> or =1, n=9) and the lower (<1, n=7) index groups. Fexofenadine was administered orally at a dose of 180 mg/day for 4 to 9 months. Pre- and post-treatment semen parameters, including total motile sperm counts (TMC) were recorded and compared. Spontaneous pregnancies after the treatment were registered. RESULTS: There was no statistically significant difference in TMC between the pre-treatment and post-treatment values in patients with higher and lower mast cell index (P> or =0.05). In both groups, nobody had a significant response to the treatment and there was no spontaneous pregnancy after the treatment. CONCLUSION: Although testicular dysfunction is closely associated with increased number of testicular mast cells, fexofenadine, a mast cell blocker, appears not having any benefit in the treatment of Turkish infertile men with a significant increase in testicular mast cells.

The assessment of sexual functions in women with male partners complaining of erectile dysfunction: does treatment of male sexual dysfunction improve female partner's sexual functions?

The aims of this prospective study were to compare sexual functioning between women with male partners who have erectile dysfunction (ED) and women without partners with ED and also to investigate the effect of the treatment of male ED on female partner's sexual function. The study included 87 women and their male partners. We divided the women into two groups: 38 women with male partners complaining of ED (ED group) and 49 women with male partners who have no ED (control group). Of the men with ED, 30 were treated with penile prosthesis implantation (n = 17) or oral sildenafil citrate (n = 13). We evaluated all the men with the International Index of Erectile Function (IIEF; Rosen, Cappelleri, Smith, Lipsky, & Pena, 1999), physical examination, and color penile Doppler ultrasound. We evaluated female sexual function with the Female Sexual Function Index (FSFI; Rosen et al., 2000) to assess sexual desire, arousal, lubrication, orgasm, satisfaction, and pain. We compared female sexual function scores between the women of the male partners with and without ED and also compared before both groups and after the treatment of male partners in the ED group. Additionally, we compare the scores according to the type of treatment given to the male partners. Sexual arousal (p = 0.009), lubrication (p = 0.001), orgasm (p = 0.006), satisfaction (p = 0.000), pain (p = 0.039), and total score (p = 0.003) were highly significantly lower in the ED group than in the control group, although sexual desire did not differ between the two groups (p = 0.515). We investigated the effect of male ED on female sexual functions and found no statistically significant differences in the presence of organic type impotence, older age, and lower erection scores on the IIEF (p = 0.53, p = 0.15, and p = 0.1, respectively). After the treatment of male ED, we observed significant improvement in sexual arousal (p = 0.001), lubrication (p = 0.002), orgasm (p = 0.000), satisfaction (p = 0.000), and pain (p = 0.002) in the women. These findings suggest that female sexual function is affected by male erection status and may improve after the treatment of male sexual dysfunction.
