Evaluation of the quality of life of patients with premature ejaculation (lifelong and acquired)

SUMMARY OBJECTIVE: The aim of this study was to evaluate the quality of life of patients with lifelong and acquired premature ejaculation and to examine its relationship with depression and anxiety. METHODS: Between February 2017 and January 2018, a total of 175 patients with premature ejaculation and 132 control men who applied to the urology department of the training and research hospital with the complaint of Premature Ejaculation were included. Patients were divided into three groups according to International Society for Sexual Medicine (ISSM) criteria as follows: Group 1, lifelong premature ejaculation; Group 2, acquired premature ejaculation, and Group 3, control group without premature ejaculation. A detailed medical history of patients was obtained and physical examinations were performed. Intravaginal ejaculation latency time (IELT) was recorded and patients were administered International Erectile Function Index-5 (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT), Sexual Health Inventory for Men (SHIM), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI)-1 and STAI-2, and Short Form-36 (SF-36). RESULTS: The mean mental component score (MCS) of the SF-36 was 51.65±6.57 in the lifelong premature ejaculation group, 49.33±8.65 in the acquired premature ejaculation group, and 61.12±11.09 in the control group (p<0.0001). The mean physical component score (PCS) was 50.99±7.43 in the lifelong premature ejaculation group, 48.32±11.58 in the acquired premature ejaculation group, and 55.17±8.10 in the control group (p<0.0001). Quality of life of premature ejaculation patients as assessed by SF-36 was lower in the subscales of physical functioning, general health perception, vitality, and role limitations due to emotional functioning, compared to the control group. CONCLUSIONS: Lifelong and acquired premature ejaculation patients deteriorate their quality of life: the deterioration in these patients' quality of life also negatively affects their depression and anxiety states.

Relation between blood vitamin B12 levels with premature ejaculation: case-control study.

The aim of this study was to investigate whether vitamin B12 levels are associated with premature ejaculation (PE). A total of 109 subjects (56 PE and 53 controls) were included in this study. PE was defined as self-reported intravaginal ejaculatory latency time (IELT) based on the Diagnostic and Statistical Manual of Mental Disorders IV criteria and those who had had an IELT of <2 min was considered as PE. All participants were evaluated using premature ejaculation diagnostic tool (PEDT), International Index of Erectile Function (IIEF) and Beck Depression Inventory (BDI). The vitamin 12 levels were measured in all subjects. The mean age between the PE and controls was comparable (p = .084). Mean IIEF and BDI scores between the two groups did not statistically differ. The mean IELT values in the PE group were significantly lower than in the control group (p < .0001). PE patients reported significantly lower vitamin B12 levels compared with the controls (213.14 vs. 265.89 ng ml-1 ; p < .001). The ROC analysis showed a significant correlation between the diagnosis of PE and lower vitamin B12 levels. This study has demonstrated that lower vitamin B12 levels are associated with the presence of PE. This work also shows a strong correlation between vitamin B12 levels and the PEDT scores as well as the IELT values.

Can ischemia-modified albumin be used as an objective biomarker for renal ischemic damage? An experimental study with Wistar albino rats.

INTRODUCTION: This study sought to evaluate the correlation of ischemia-modified albumin (IMA) with time-dependent renal ischemic injury. METHODS: We established 5 groups of 8 Wistar albino rats as follows: sham, 10 minutes of renal ischemia, 20 minutes of renal ischemia, 30 minutes of renal ischemia, and 40 minutes of renal ischemia. Renal ischemia was established by occlusion of the right renal pedicle. Blood samples were obtained after exploration of the renal pedicle in the sham group and after thoracotomy and directly from the cardiac chambers at the end of the ischemic period in the other groups. The ischemic kidneys were removed for histopathological evaluation, and the rats were killed. RESULTS: There were significant differences among the IMA levels of the 5 groups (P = .0013). Pathological examination showed that renal ischemic injury corresponded to the duration of ischemia. In the group analysis, the pathological evaluation scores were significantly different among the groups (P < .001). CONCLUSIONS: This study shows that IMA levels can be used as a nonselective biomarker for renal ischemic injury. However, further studies are needed to support our findings.
