Purpose: To evaluate the changes in dynamic pupillometry in patients with idiopathic overactive bladder (OAB)., Methods: The study included 40 female patients with idiopathic OAB and 40 healthy female volunteers as a control group. Demographic and clinical data were recorded. Dynamic pupillometric parameters were measured with a commercially available unit (MonPack One, Metrovision, France) at baseline and on the 30th day of treatment with an antimuscarinic treatment (drug-agent) (solifenacin 5 mg daily). Initial, minimum, maximum and mean pupil diameters, the latency and duration of contraction and dilatation of the pupil, the amplitude of contraction and dilatation velocity were automatically measured and compared between the groups., Results: There were no significant differences between two groups with respect to age and body mass index (p = 0.288, 0.755, respectively). The measurements of initial, minimum and mean pupil diameters were significantly lower in patients with OAB compared to healthy controls (p = 0.007, 0.002, 0.001, respectively). OAB patients had significantly longer latency of pupil dilatation, latency of pupil contraction and shorter duration of pupil contraction than control group (p = 0.028, 0.029, 0.021, respectively). After the antimuscarinic treatment, latency of pupil contraction, latency of pupil dilatation and duration of pupil contraction shortened significantly (all p < 0.001). Pupil dilatation velocity increased significantly during the treatment (p < 0.001)., Conclusions: The dynamic pupillometric findings in this study imply impaired autonomic dysfunction, mostly the increased parasympathetic action, in OAB patients and the modulatory effects of antimuscarinic treatment.

Objective: We determine the comorbid conditions associated with syncope in women. In addition, we hypothesize a higher proportion of autonomic comorbid conditions during the female reproductive age., Methods: We identified a cohort of patients admitted to US hospitals with the principal diagnosis of syncope. We compare patient demographics stratified by gender as well as syncope associated comorbidities. We compared these comorbidities in female of reproductive age (15-45) to men as control., Results: From a total sample of 305,932, females constituted 56.7% (n = 173,434). Females were slightly older (mean age 70.9 +/- 17.9 vs. 66.7 +/- 17.3; P < 0.0001); with similar racial distribution (white 57.8 vs. 57.5%), and similar length of hospital stay (mean 2.66 +/- 2.63 vs. 2.68 +/- 2.72 days; P > 0.05). Females had higher proportion of migraine (1.65 vs. 1.29%; odds ratio 'OR' 1.29; 95% confidence interval 'CI' 1.21, 1.36); chronic fatigue syndrome (1.73 vs. 1.3%; OR 1.32; 95% CI 1.25, 1.4); gastroparesis (0.2 vs. 0.12%; OR 1.64; 95% CI 1.35, 1.98); interstitial cystitis (0.07 vs. 0.01%; OR 7.44; 95% CI 4.10, 13.5); and postural tachycardia syndrome (0.49 vs. 0.44%; OR 1.1; 95% CI 1.001, 1.23). Orthostatic hypotension was not different between the groups (P = 0.24). When the sample was stratified by age category, the odds ratio for gastroparesis, orthostatic hypotension, and postural tachycardia syndrome was increased (P < 0.05)., Interpretation: A higher proportion of autonomic dysfunction was present in women compared to men. In addition, these comorbid autonomic conditions were especially prominent during the female reproductive age.

This study was planned to investigate the dysfunction of the autonomic nervous system in fibromyalgia syndrome (FM) using sympathetic skin responses (SSR) and RR interval analysis. Thirty-four FM and 22 healthy subjects were recruited for the study. They were questioned for symptoms that are characteristic for FM and medical outcome study short form-36 (SF-36) was used to determine the quality of life of the subjects. Tender points were counted and the disease duration was noted. SSR was recorded from palm and sole with stimulation of contralateral median and tibial nerves respectively. R-R interval variation was evaluated at rest (R%) and during deep breathing (DR%). The mean ages of the patients were 37+/- 10.2 and 37+/-10.6, respectively. The mean tender point count was 14.9+/-2.3 and the disease duration was 16.6+/-12.1 months. The symptoms were discrepant in FM (P<0.001). The scores of the eight items of SF-36 in FMS patients were significantly lower than the control group (P<0.001). We could not elicit SSR in five FM patients (15%) from the sole and in two patients (6%) from the palm. The latencies of SSR recorded from both palms and soles of FM patients were significantly longer than healthy subjects (P<0.001). The mean amplitude of SSR recorded from both palm and sole was not statistically different from control subjects (P>0.05). RRIV obtained from FM and the control subjects at rest and during deep breathing showed that the decrease in DR% was significant compared to normal subjects (P<0.001). As a result, we can state that sympathetic as well as parasympathetic nervous system dysfunction occurs in FM patients and this abnormality could be determined by SSR and RRIV analysis.
