Effect of psychosocial trauma and stress on sexual dysfunction in women with endometriosis.

BACKGROUND: Endometrial tissue plays an important role in the regulation of female fertility and there is evidence that endometrial pathology (including endometriosis) is closely related to endocrine disorders. On the other hand, various neuroendocrine changes can be significantly affected by psychosocial stress. In connection with these findings, we tested the relationship between neuroendocrine changes, sexual dysfunction, psychosocial/traumatic stress, and dissociative symptoms in women with endometriosis. METHODS: A total of 65 patients with endometriosis were included in the study. Clinical examinations were focused on the biochemical analysis of neuroendocrine markers of endometriosis (cancer antigen 125 [CA 125] and cancer antigen 19-9 [CA 19-9]), estradiol, psychometric evaluation of sexual dysfunction, psychosocial/traumatic stress, and dissociative symptoms. RESULTS: The results showed significant Spearman correlations between the values of the revised range of sexual difficulties for sexual dysfunction (Revised Female Sexual Distress Scale), psychosocial/traumatic stress (Trauma Symptoms Checklist) (R = 0.31), and dissociative symptoms (Somatoform Dissociation Questionnaire) (R = 0.33). Positive correlations were also found between CA 125 and CA 19-9 (R = 0.63), and between CA 125 and the results of the values of the revised scale of sexual difficulties for sexual dysfunction (Revised Female Sexual Distress Scale) (R = 0.29). Also psychosocial/traumatic stress (Trauma Symptoms Checklist) significantly correlated with CA 125 (R = 0.38) and with CA 19-9 (R = 0.33). CONCLUSION: These results represent the first findings regarding the relationship of the neuroendocrine markers CA 125 and CA 19-9 and sexual dysfunction with trauma/stress-related symptoms and dissociative symptoms in women with endometriosis.

Sexual Dysfunctions in Obese Women Before and After Bariatric Surgery.

BACKGROUND Obesity and associated comorbidities increase the probability of sexual disorders. The present study evaluated sexual satisfaction levels in obese women prior to and following bariatric surgery, utilizing the validated Female Sexual Function Index (FSFI) to also evaluate the sexual satisfaction in obese and non-obese women. MATERIAL AND METHODS 60 obese women (mean initial BMI of 43.7±5.9 kg/m²; mean age of 41.7±10.8 years) were administered the questionnaire on sexual function (FSFI) preceding bariatric surgery (laparoscopic adjustable gastric banding, 22 women; gastric plication, 33 women; and biliopancreatic diversion, 5 women), 6 months and 12 months after the procedure, i.e., following substantial weight reduction (final mean BMI of 35.5±5.5 kg/m²). The control group comprised 60 non-obese women (mean BMI of 22.2±1.9kg/m²; mean age of 36.4±10.7 years). RESULTS Our findings indicate that baseline sexual function in the preoperative obese females was significantly lower than in non-obese women, with p<0.01 in each domain. Data gathered at the 6- and 12-month points following the procedure indicated no significant difference. Before the procedure, 31 obese subjects (51.6%) exceeded the cutoff for FSD, at the 6-month evaluation point, 17 women (39.5%) exceeded the cutoff, and at 12 months postoperatively, 18 subjects (41.9%) exceeded the cutoff, indicative of FSD. Among the non-obese controls, only 9 subjects (15%) exceeded the cutoff threshold. CONCLUSIONS These findings show that substantive weight reduction resulting from bariatric surgery results in reduced sexual dysfunction in female subjects.

Oncological markers CA-125, CA 19-9 and endometriosis.

The endometrium tissue is functionally androgen related which plays an important role in women's fertility regulation. In addition recent findings show that endometrium related pathology is closely linked to disrupted androgen biosynthesis and associated regulatory functions. These findings also suggest that androgens might play an important role in endometrium related cancer pathology with significant implications for treatment.Based on these findings, we have assessed 50 female outpatients with endometriosis and the clinical investigations were focused on biochemical serum analysis of DHEAS, oncological markers CA-125 and CA 19-9, estradiol, thyreothropic hormone, and prolactin.The results show significant Spearman correlations of CA-125 and CA 19-9 with dehydroepiandrosterone- DHEA-S (R = 0.52 resp. R = 0.49).This result represents 1st reported finding documenting androgen related increase of CA-125 and CA 19-9 levels as significant markers of endometrium pathology and it is possible to assume that these potential biomarkers could have clinical importance with respect to timely diagnosis.

Preictal dynamics of EEG complexity in intracranially recorded epileptic seizure: a case report.

Recent findings suggest that neural complexity reflecting a number of independent processes in the brain may characterize typical changes during epileptic seizures and may enable to describe preictal dynamics. With respect to previously reported findings suggesting specific changes in neural complexity during preictal period, we have used measure of pointwise correlation dimension (PD2) as a sensitive indicator of nonstationary changes in complexity of the electroencephalogram (EEG) signal. Although this measure of complexity in epileptic patients was previously reported by Feucht et al (Applications of correlation dimension and pointwise dimension for non-linear topographical analysis of focal onset seizures. Med Biol Comput. 1999;37:208-217), it was not used to study changes in preictal dynamics. With this aim to study preictal changes of EEG complexity, we have examined signals from 11 multicontact depth (intracerebral) EEG electrodes located in 108 cortical and subcortical brain sites, and from 3 scalp EEG electrodes in a patient with intractable epilepsy, who underwent preoperative evaluation before epilepsy surgery. From those 108 EEG contacts, records related to 44 electrode contacts implanted into lesional structures and white matter were not included into the experimental analysis.The results show that in comparison to interictal period (at about 8-6 minutes before seizure onset), there was a statistically significant decrease in PD2 complexity in the preictal period at about 2 minutes before seizure onset in all 64 intracranial channels localized in various brain sites that were included into the analysis and in 3 scalp EEG channels as well. Presented results suggest that using PD2 in EEG analysis may have significant implications for research of preictal dynamics and prediction of epileptic seizures.

Dissociative symptoms reflect levels of tumor necrosis factor alpha in patients with unipolar depression.

Recent evidence indicates that the nature of interactions between the nervous system and immune system is important in the pathogenesis of depression. Specifically, alterations in pro-inflammatory cytokines have been related to the development of several psychological and neurobiological manifestations of depressive disorder, as well as to stress exposure. A number of findings point to tumor necrosis factor alpha (TNF-α) as one of the central factors in these processes. Accordingly, in the present study, we test the hypothesis that specific influences of chronic stressors related to traumatic stress and dissociation are related to alterations in TNF-α levels. We performed psychometric measurement of depression (Beck Depression Inventory [BDI]-II), traumatic stress symptoms (Trauma Symptom Checklist [TSC]-40), and psychological and somatoform dissociation (Dissociative Experiences Scale [DES] and Somatoform Dissociation Questionnaire [SDQ]-20, respectively), and immunochemical measure of serum TNF-α in 66 inpatients with unipolar depression (mean age 43.1 ± 7.3 years). The results show that TNF-α is significantly related to DES (Spearman R=-0.42, P<0.01), SDQ-20 (Spearman R=-0.38, P<0.01), and TSC-40 (Spearman R=-0.41, P<0.01), but not to BDI-II. Results of the present study suggest that TNF-α levels are related to dissociative symptoms and stress exposure in depressed patients.

Depression, traumatic stress and interleukin-6.

BACKGROUND: Recent evidence indicates that various types of interactions between nervous and immune system are important in pathogenesis of depression. These findings show that a significant role in developing depression play pro-inflammatory cytokines that may mediate its psychological, and neurobiological manifestations. Great importance among these cytokine molecules plays interleukin-6 (IL-6). There is growing evidence that this inflammatory process related to depression may be influenced by psychological stress as well as organic inflammatory conditions. These findings suggest that specific influences related to traumatic stress and dissociation could be found in close relationship to increased level of cytokine IL-6. METHODS: In the present study we have performed psychometric measurement of depression (BDI-II), traumatic stress symptoms (TSC-40) and dissociation (DES, SDQ-20), and immunochemical measure of serum IL-6 in 40 inpatients with unipolar depression (mean age 42.3+/-6.8). RESULTS: The results show that IL-6 is significantly correlated to BDI-II (Spearman R=0.47, p<0.01), TSC-40 (Spearman R=0.32, p<0.05), SDQ-20 (Spearman R=0.34, p<0.05) but not to DES (Spearman R=0.25, p=0.11). CONCLUSION: The findings of the present study indicate that increased level of IL-6 in depression could be directly related to symptoms of traumatic stress and somatoform dissociation.

Dissociative processes, multiple personality, and dream functions.

From ancient times on, our dream processes were thought to be the uncovering of unknown connections. It may be that there is some basis to this belief and that dreams truly represent a mirror of our unconscious and not only random processes moving along according to some brain "computation." These ideas are supported by some findings that involve connections among dissociative processes, hypnosis, and multiple personality disorder (MPD). From this point of view, MPD represents a very interesting theoretical problem, which may be understood as an extreme example of the dissociative nature of the human psyche. This in turn leads to an understanding of the complex structure of the human psyche and corresponds perfectly to our experience, which says that the pathological often sheds new light on the normal and physiological.
