    (Korean Continence Soc, 2017) Solmaz, Volkan; Albayrak, Sebahattin; Tekatas, Arslan; Aksoy, Durdane; Gencten, Yusuf; Inanir, Sema; Erdemir, Fikret
    Purpose: In this study, we investigated overactive bladder (OAB) functions in male patients who used antidepressant drugs (ADs) that were previously examined in female patients, based on conflicting data in literature regarding the effects of AD on OAB and the differences between male and female urinary system physiologies (anatomical and hormonal). Methods: The study included 202 male patients (a control group of 90 healthy subjects, and an experimental group of 112 patients taking ADs for different disorders). All the patients completed the overactive bladder-validated 8 (OAB-V8) questionnaire, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and the Beck Depression Inventory (BDS). Results: The OAB-V8, ICIQ-SF, and BDS scores for the antidepressant users were significantly higher than those of the control group. The highest prevalence of OAB symptoms was observed in patients taking venlafaxine (68.2%), and the lowest prevalence was in patients taking sertraline (28.0%). Moreover, the frequency of OAB between the antidepressant groups was statistically significant. The univariate logistic regression analyses showed a significant relationship between the presence of OAB, antidepressant usage, BDS score, and the age of a patient. In the multivariate logistic regression analyses, the association between the presence of OAB and antidepressant usage was statistically significant. Conclusions: The present study showed that the incidence of OAB and the severity of OAB symptoms increased in males using antidepressants for various disorders. This may have been due to unique pharmacological effects, on a molecular or individual level, of serotonin-norepinephrine reuptake inhibitors.

    Evaluation of the association between sexual dysfunction and demyelinating plaque location and number in female multiple sclerosis patients
    (Taylor & Francis Ltd, 2018) Solmaz, Volkan; Ozlece, Hatice Kose; Him, Aydin; Gunes, Ayfer; Cordano, Christian; Aksoy, Durdane; Celik, Yahya
    Purpose: To investigate the frequency of sexual dysfunction (SD) in female multiple sclerosis (MS) patients and to explore its association with the location and number of demyelinating lesions. Material and Methods: We evaluated 42 female patients and 41 healthy subjects. All patients underwent neurological examination and 1.5 T brain and full spinal MRI. All subjects completed the female sexual function index (FSFI), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Short-Form 36 Quality of Life Scale (SF-36). All participants were also evaluated for serum thyroid stimulating hormone (TSH), T4, estradiol, and total testosterone. Results: No statistically significant differences between the MS and control groups were found for age, body mass index (BMI), serum TSH, T4, E2, and total testosterone level. MS patients had a statistically significantly lower FSFI and SF-36 scores and higher BDI and BAI scores compared with healthy subjects. The location and number of demyelinating lesions were not associated with SD. Conclusion: In our cohort, this difference in SD appears unrelated to the location and number of demyelinating lesions. These findings highlight the importance of the assessment and treatment of psychiatric comorbidities, such as depression and anxiety, in MS patients reporting SD.

    Investigation of Nerve Conduction Studies of Carpal Tunnel Syndrome Cases With Different Risk Factors: An Electrodiagnostic Study
    (Lippincott Williams & Wilkins, 2017) Solmaz, Volkan; Yavuz, Selcuk; Inanir, Ahmet; Aksoy, Durdane; Pektas, Elmas; Tekatas, Aslan; Kurt, Semiha G.
    Purpose:The aim of this study was to determine whether there are electrodiagnostic differences between carpal tunnel syndrome (CTS) patients with diabetes mellitus, CTS + hypothyroidism (HT), CTS + fibromyalgia syndrome, CTS + rheumatoid arthritis (RA), and idiopathic CTS cases, by comparing nerve conduction studies.Methods:This research examined electrophysiologic studies of 47 untreated HT + CTS, 47 diabetes mellitus + CTS, 49 RA + CTS, 52 fibromyalgia syndrome + CTS, 50 idiopathic CTS cases, and a healthy control group of 50 individuals (a total of 293 patients and 433 hands with CTS).Results:There were no significant differences between the groups in terms of sex and age. There was no significant difference between the CTS groupsin terms of numberswith mild, moderate, and severe CTS. When the CTS groups were compared with the control group, in all CTS groups on both left and right hands, there was a significant prolongation in median motor latency and median sensory latency (in the 3rd finger); also a significant decrease in median sensory velocity in the 3rd finger. In diabetes mellitus, HT, and RA groups, the median motor amplitudes in both hands were significantly decreased compared with the idiopathic group. There was a moderate significant negative correlation between disease duration and median motor amplitudes (of both right and left sides) in RA (right; P = 0.028, r = 0.761, left; P = 0.041, r = 0.694) and HT groups (right; P = 0.035, r = 0.637, left; P = 0.049, r = 0.697).Conclusions:Electrodiagnostic results showed both demyelinating injury and axonal damage in diabetes mellitus, HT, and RA patients with CTS, in these patients during treatment for CTS. Early treatment planning should include the risk factor diseases.

    Neuroprotective Effects of Eexenatide in a Rotenone-Induced Rat Model of Parkinson's Disease
    (Elsevier Science Inc, 2017) Aksoy, Durdane; Solmaz, Volkan; Cavusoglu, Turker; Meral, Ayfer; Ates, Utku; Erbas, Oytun
    Backround: Several studies suggest an association between Parkinson's disease (PD) and type 2 diabetes mellitus; these 2 diseases are both known to affect the common molecular pathways. As a synthetic agonist for the glucagon-like peptide 1 receptor, exenatide has been evaluated as a neuroprotective agent in multiple animal models. Rotenone models of PD have great potential for the investigation of PD pathology and motor and nonmotor symptoms, as well as the role of gene environment interactions in PD causation and pathogenesis. Therefore, in this study, the neurochemical, behavioral and histologic effects of exenatide on a rotenone-induced rat model of PD were examined. Materials and Methods: Eighteen adult male rats were randomly divided into the following 3 groups (n = 6): 1 group received stereotaxical infusion of dimethyl sulfoxide (vehicle, group 1) and the others received stereotaxical infusion of rotenone (groups 2 and 3). Apomorphine-induced rotation test was applied to the rats after 10 days. Thereafter, group 2 was administered isotonic saline, whereas group 3 was administered exenatide for 28 days. Results: Malondialdehyde and tumor necrosis factor alpha levels increased in the rats with PD induced by rotenone, whereas malondialdehyde and tumor necrosis factor alpha levels markedly decreased in the rats treated with exenatide. The apomorphine-induced rotation test scores of exenatide-treated rats were determined to be lower compared with the untreated group. Additionally, treatment with exenatide significantly reduced the loss of dopaminergic neurons in striatum. Conclusions: These results have shown that exenatide has neuroprotective, anti-inflammatory and antioxidant effects in a rotenone-induced rat model of PD.

    (Cukurova Univ, Fac Medicine, 2018) Solmaz, Volkan; Genc, Elmas Pekdas; Aksoy, Durdane; Cevik, Betul; Kurt, Semiha Gulsum; Benli, Ismail
    Purpose: We aimed to investigate the systemic inflammation status by analyzing the Neutrophil/Lymphocyte (N/L) ratio, Erythrocyte Sedimentation Rate (ESR), and C - reactive protein (CRP) in patients with Parkinson's disease (PD). Materials and Methods: 101 PD patients, and 60 healthy subjects of similar age and gender were include in this study. The demographic data and duration of the disease, the drugs, duration of usage of Parkinson drugs, Hoehn-Yahr stage were noted. After full neurological examination blood samples are collected and neutrophil, lymphocyte counts, high sensitive CRP, ESR levels are detected. Results: The N/L ratio and the CRP levels were statistically higher in Parkinson's group. There was a statistically significant but weak positive correlation between the CRP levels and the N/L ratio with the disease duration. Similarly, there was a statistically significant but weak positive correlation between the CRP levels and the N/L ratios with Hoehn-Yahr stages. When the N/L rates of the Parkinson's patients were correlated with the CRP and the ESR levels separately, it was observed that there was a weak but statistically significant correlation between the CRP and the N/L ratio Conclusion: N/L ratio, and CRP levels, which are very important indicators of peripheral inflammation, was higher in PD. Our findings suggest that these biochemical markers may have a predictive value for the diagnosis of PD.
