The irritable bowel syndrome (IBS) is a common functional bowel disorder diagnosed by characteristic symptoms. It is often associated with gynecologic symptoms, especially chronic pelvic pain (CPP). IBS symptoms worsen during menstruation and are correlated with increased levels of various perimenstrual symptoms. Psychosocial factors including depression, somatization, substance abuse, and childhood abuse are similar in IBS and CPP. IBS predisposes women to undergo hysterectomy and negatively influences pain improvement postoperatively. Therefore, IBS should be considered in the differential diagnosis of CPP. Collaboration between gynecologists and gastroenterologists is needed in the care of women with CPP and IBS as well as in the conduct of additional research on the relationship of these two disorders.

This study confirms the previously studied findings by using a more rigorous methodology concerning the association of sexual victimization history and irritable bowel syndrome or inflammatory bowel disease. Structured psychiatric and sexual trauma interviews were given to 28 patients with irritable bowel syndrome and 19 inflammatory bowel disease, and the prevalence rates of sexual victimization in the 2 groups were compared. A logistic regression analysis was performed to summarize the differences between patients who had severe trauma and those who had none, and to account for intercorrelations among the study variables. Results showed that patients with irritable bowel syndrome were more likely to have a history of previous sexual victimization. The odd ratios for current and lifetime psychiatric disorders in the 9 patients who had experienced severe forms of victimization showed that they were at significantly greater risk for affective, anxiety, and somatoform disorders as well as substance abuse and sexual dysfunction. It was also demonstrated that the best predictors of having experienced severe forms of victimization were gender, the number of medically unexplained physical symptoms, and self-reported anxiety and hostility. This study suggests that irritable bowel syndrome may be part of a chronic adjustment to previous sexual victimization in some patients.

Corticotropin-releasing factor (CRF) co-ordinates the neural, endocrine and immune responses of the body to stress. Several studies have implicated CRF in the etiology of anxiety, depression, substance abuse, stress-related gastrointestinal disorders and preterm labor, and intensive research into the design of safe and effective CRF antagonists is currently being pursued in several laboratories. Recently, improvements have been made not only in brain penetrance and in vivo activity in preclinical models for anxiety, depression and irritable bowel syndrome, but also in structural diversity for these compounds. Clinical data for R-121919 (NBI-30775; Neurocrine Biosciences Inc) raises the expectation that safe and potent CRF antagonists might be useful as drugs for the treatment of human diseases.

Research has shown a strong relationship between childhood trauma and psychological difficulties in later life; more recent research has indicated that the long-term effects are even greater for physical illness. These long-term effects have highlighted Posttraumatic Stress Disorder (PTSD) as a possible mediator variable. The illnesses identified include, but are not limited to, eating disorders, substance abuse, phobias, multiple personality disorders, irritable bowel syndrome, rheumatoid arthritis, and autoimmune disorders. Childhood trauma is an area of interdisciplinary interest; therefore, a variety of disciplines have been carrying out research in this area. This article is an integrative review of the literature over the last five years across disciplines, including nursing, medicine, psychology, education, social services, and government agencies. The review searched for themes, common constructs, and definitions, plus gaps in the present literature that need to be addressed. Particular attention was paid to measurement tools, and the importance of post traumatic stress disorder. Databases included were Medline, Proquest, Canadian Health Network (CHN), Canadian Business and Current Affairs (CBCA) Education, Educational Resources Information Center (ERIC) Plus, Cumulative Index to Nursing & Allied Health Literature (CINAHL), American Psychological Association Database Information (PsychINFO), and Cochrance.

Chronic pelvic pain in women is a difficult subject that challenges the gynecologist in practice. Possible gynecological causes are endometriosis, adhesions/PID, pelvic varicosis and ovarian retention syndrome/ovarian remnant syndrome. Other somatic causes are irritable bowel syndrome, bladder pain syndrome and fibromyalgia.Confirmed psychosocial factors contributing to chronic pelvic pain are comorbidity with anxiety disorders, substance abuse or depression, but the influence of social factors is less certain. The connection to physical and sexual abuse also remains unclear. Important diagnostic steps are studying the patient's history, a gynecological examination and laparoscopy. Multidisciplinary therapeutic approaches are helpful. Basic psychosomatic care and psychotherapy should be integrated into the therapeutic concept at an early stage of the disease.

Interventions based on mindfulness have become increasingly popular. This article reviews the empirical literature on its effects on mental and physical health, discusses presumed mechanisms of action as well as its proposed neurobiological underpinning. Mindfulness is associated with increased well-being as well as reduced cognitive reactivity and behavioral avoidance. It seems to contribute to enhance immune functions, diminish inflammation, diminish the reactivity of the autonomic nervous system, increase telomerase activity, lead to higher levels of plasmatic melatonin and serotonin. It enhances the quality of life for patients suffering from chronic pain, fibromylagia and HIV infection. It facilitates adaptation to the diagnosis of cancer and diabetes. It seems to lead to symptomatic improvement in irritable bowel syndrome, chronic fatigue syndrome, hot flashes, insomnia, stress related hyperphagia. It diminishes craving in substance abuse. The proposed mechanism of action are enhanced metacognitive conscience, interoceptive exposure, experiential acceptance, self-management, attention control, memory, relaxation. Six mechanism of actions for which neurological underpinnings have been published are: attention regulation (anterior cingulate cortex), body awareness (insula, temporoparietal junction), emotion regulation (modulation of the amygdala by the lateral prefrontal cortex), cognitive re-evaluation (activation of the dorsal medial prefrontal cortex or diminished activity in prefrontal regions), exposure/extinction/reconsolidation (ventromedial prefrontal cortex, hippocampus, amygdala) and flexible self-concept (prefrontal median cortex, posterior cingulated cortex, insula, temporoparietal junction). The neurobiological effects of meditation are described. These are: (1) the deactivation of the default mode network that generates spontaneous thoughts, contributes to the maintenance of the autobiographical self and is associated with anxiety and depression; (2) the anterior cingulate cortex that underpins attention functions; (3) the anterior insula associated with the perception of visceral sensation, the detection of heartbeat and respiratory rate, and the affective response to pain; (4) the posterior cingulate cortex which helps to understand the context from which a stimulus emerges; (5) the temporoparietal junction which assumes a central role in empathy and compassion; (6) the amygdala implicated in fear responses. The article ends with a short review of the empirical basis supporting the efficacy for mindfulness based intervention and suggested directions for future research.
