Single voxel proton magnetic resonance spectroscopy in women with and without intimate partner violence-related posttraumatic stress disorder.

Preliminary in vivo proton magnetic spectroscopic ((1)H-MRS) studies of N-acetylaspartate (a putative marker of neuronal viability and function) in combat veterans and maltreated children with posttraumatic stress disorder (PTSD) suggest altered neuronal integrity in anterior cingulate and medial temporal lobe structures. In this study, (1)H-MRS was used to measure N-acetylaspartate (NAA), choline (Cho) and myo-inositol (mI) relative to creatine (Cr) in the anterior cingulate of 16 women with histories of intimate partner violence (7 with a DSM-IV diagnosis of PTSD, 9 without PTSD) and 11 healthy, non-abused comparison subjects. The relationship between anterior cingulate chemistry and performance on the Stroop Color-Word task and Part B of the Trail Making Test was also examined. There were no significant differences in anterior cingulate or occipital gray matter metabolite ratios of NAA/Cr and Cho/Cr between intimate partner violence and healthy comparison subjects. Intimate partner violence subjects with PTSD had significantly higher anterior cingulate Cho/Cr than intimate partner violence subjects without PTSD. There was evidence that the subjects with PTSD suffered more severe intimate partner violence as measured by the Conflict Tactics Scale-Revised. Metabolite ratios were not significantly correlated with performance on the Stroop or Trails B. Our findings, in agreement with earlier studies, showed significant alterations in anterior cingulate chemistry in women with PTSD. In contrast to other studies, we found an increase in Cho/Cr rather than a decrease in NAA/Cr, indicating alterations in glia, instead of neuronal dropout.

Risk factors for painful bladder syndrome in women seeking gynecologic care.

The aim of this cross-sectional study was to report risk factors for painful bladder syndrome in women. We surveyed 645 women presenting for care to general gynecology clinics and a vulvar specialty clinic using a standardized questionnaire and validated outcome measures. We used two definitions for painful bladder syndrome, based on the O'Leary-Sant interstitial cystitis symptom and problem indices. Of those women surveyed, 29.5% met broader criteria and 8.5% met more restrictive criteria for painful bladder syndrome. After adjusting for confounders, bladder pain was significantly associated with current smoking, irritable bowel syndrome, and a generalized pain disorder. Tobacco use, the only modifiable association noted on multivariate analysis, has not been previously identified to our knowledge.

Vulvar disease: a pelvic floor pain disorder?

OBJECTIVE: The purpose of this study was to compare the rates of painful bladder syndrome and functional bowel disorders in women with vulvar disease and control subjects. STUDY DESIGN: In this cross-sectional survey, a questionnaire that contained validated outcome measures was administered to women who were seeking care in a vulvar disease clinic and in general gynecology clinics. RESULTS: Women who were seen at a vulvar disease clinic were 2.18 (95% CI, 1.19, 3.97) times more likely to have painful bladder syndrome and 2.13 (95% CI, 1.35, 3.35) times more likely to have functional bowel disorders than general gynecology clinic control subjects after multivariable analyses. CONCLUSION: Painful bladder syndrome and functional bowel disorders are more prevalent in women who are seen at a vulvar disease clinic than gynecology clinics control subjects. These associations may reflect a common origin for these disorders in certain women. These findings lay the groundwork for future research to investigate a potential "pelvic floor pain disorder," which is a disease entity that would combine the diagnostic criteria for vulvar, bladder, and bowel pain disorders.

Vulvar cellular angiofibroma: a case report.

Cellular angiofibroma is a benign growth initially described in 1997, with few reports to date. A 31-year-old woman presented with a 3-year history of a small left labial mass, which had recently increased in size to 5 cm, and was clinically thought to be a lipoma. A simple excision was performed. Histologically, the mass was consistent with a cellular angiofibroma. Ten months later, the growth has not recurred. Cellular angiofibroma is a rare, benign mesenchymal lesion typically occurring on the vulva, and should be considered in the differential diagnosis of a painless, soft, vulvar mass.

Pelvic floor symptoms and lifestyle factors in older women.

OBJECTIVES: To measure the prevalence of pelvic floor symptoms in noncare-seeking older women and the association between symptoms and lifestyle factors. METHODS: Women enrolled at one site of the Women's Health Initiative Hormone Therapy clinical trial completed a questionnaire, modified from the Pelvic Floor Distress Inventory, on bladder, bowel, and prolapse symptoms. Individual symptoms and symptom groups were examined in a cross-sectional analysis. RESULTS: In the 297 women who participated, mean age was 68.2 years, mean body mass index (BMI) was 30.2 kg/m(2), and median vaginal parity was 3. The median number of symptoms endorsed was 3 (range 0-18). The most prevalent symptoms were stress urinary incontinence (51.2%), urge urinary incontinence (49.2%), urinary frequency (29.0%), straining for bowel movements (25.0%), a sense of incomplete bowel movements (34.8%), and involuntary loss of gas (33.0%). The symptom groups most frequently endorsed were stress urinary incontinence, overactive bladder, obstructive voiding, and obstructive colorectal groups (>/=1 symptom per group in 51.2%, 61.3%, 40.8%, and 48.3%, respectively). In analyses adjusted for age, BMI, caffeine ingesting, smoking, and exercise, older women more frequently reported incomplete bladder emptying (adjusted OR 3.4, 95% CI 1.3, 9.2), weak urinary stream (adjusted OR 6.4, 95% CI 2.0, 20.0), intermittent urinary stream (adjusted OR 4.0, 95% CI 1.6, 10.4), and a feeling of incomplete bowel movements (adjusted OR 2.7, 95% CI 1.2, 5.9). Women who exercised weekly had less fecal urgency (adjusted OR 0.3, 95% CI 0.2, 0.8). Coffee drinking was associated with difficulty emptying the bladder (adjusted OR 8.6, 95% CI 1.4, 55.0) and weak stream (adjusted OR 5.3, 95% CI 1.5, 19.0). CONCLUSIONS: Pelvic floor symptoms, especially urinary incontinence and irritative and obstructive urinary and bowel symptoms, are common in older women. Some symptoms are associated with potentially modifiable lifestyle factors.

Vulvar granuloma fissuratum: a description of fissuring of the posterior fourchette and the repair.

OBJECTIVE: To describe the characteristics of women who experience chronic fissuring of the posterior fourchette and the outcome of treatment administered. METHODS: We conducted a retrospective review of 42 women with granuloma fissuratum presenting for care between January 1, 1995, and December 31, 2003. Women underwent medical management first, and if improvement was minimal, perineoplasty was recommended. Dyspareunia and vulvar symptom scores, including itching, burning, and pain, before and after treatment were compared. RESULTS: Twenty women were managed nonoperatively, while 22 women underwent perineoplasty. The median age at diagnosis of granuloma fissuratum was 42.5 years (range 26-78). The fissure resolved in 13 of 20 women (65%) who were managed nonoperatively and in 21 of 22 women (95%) who underwent perineoplasty. Of the 11 women sexually active after perineoplasty, all had preoperative dyspareunia; it resolved in 7 (64%) women. Among the 13 women managed nonsurgically who had resolution of the fissure, 7 women were sexually active after treatment and dyspareunia resolved in 2 (29%) women. Other vulvar symptoms, such as burning, itching, pain, and discharge, showed no significant improvement after either surgical or nonsurgical treatment. CONCLUSION: Although fissuring is common with some vulvar dermatoses, such as lichen sclerosus and contact vulvitis, and often resolves with the appropriate medical management, fissuring may also occur as a primary finding and may benefit from perineoplasty.

Leiomyosarcoma of the vulva: a case report.

BACKGROUND: Leiomyosarcoma of the vulva is a rare gynecologic malignancy, comprising approximately 1% of vulvar cancers. CASE: A 36-year-old woman was referred for a slowly growing painless vulvar mass that was initially thought to be a Bartholin's duct cyst but was cancerous upon biopsy. A modified radical vulvectomy was performed, and pathology revealed a grade 1 leiomyosarcoma. Thirteen months later, the tumor had not recurred. CONCLUSION: Vulvar cancer must be considered in patients with a suspected Bartholin duct cyst that demonstrates atypical features. A biopsy should be obtained if the mass appears firm or solid on palpation, is ulcerated or presents in a slightly different location from the usual area of the Bartholin gland.

Adult psychopathology and intimate partner violence among survivors of childhood maltreatment.

Childhood maltreatment is associated with psychopathology and revictimization in adulthood. Whether different types of childhood maltreatment have different long-term consequences, however, is largely unknown. The participants in this study included 42 female victims of intimate partner violence and 30 women with no history of serious trauma. These women completed measures of their trauma history, current psychological symptoms, and severity of current abuse. Regression-based techniques were used to assess the relationships among these constructs. Childhood maltreatment was associated with current distress and current conflict in relationships. There was a positive relationship between number of types of childhood traumatization and psychopathology. Symptoms of post-traumatic stress disorder (PTSD) and depression were negatively associated with current relationships involving physical assault. This work underscores the importance of assessing multiple types of childhood maltreatment and of considering the cumulative effects of such experiences.

Brain morphometry in female victims of intimate partner violence with and without posttraumatic stress disorder.

BACKGROUND: To examine neuroanatomical morphometry in adult female victims of intimate partner violence with and without posttraumatic stress disorder. METHODS: Seventeen nonvictimized comparison subjects and 22 victims of intimate partner violence, 11 with and 11 without posttraumatic stress disorder, were studied. Using quantitative magnetic resonance imaging, three mesial temporal lobe areas were measured: hippocampus, amygdala, and parahippocampal gyrus. Additionally, whole brain morphometry provided fluid, gray, and white matter volumes of the cortex and cerebellum for exploratory analyses. Relationships of morphometric measures to symptoms, abuse history, and neuropsychological function were examined. RESULTS: Intimate partner violence subjects with posttraumatic stress disorder did not demonstrate significantly smaller hippocampal or other mesial temporal lobe volumes. Overall, intimate partner violence subjects had smaller supratentorial cranial vaults and smaller frontal and occipital gray matter volumes relative to nonvictimized comparison subjects. Supratentorial cranial vault volume was negatively correlated with severity of childhood physical abuse, but not with intimate partner violence or posttraumatic stress disorder severity. Trails B performance was negatively correlated with frontal gray matter volume. CONCLUSIONS: These findings are inconsistent with prior reports of smaller hippocampal volumes in patients with posttraumatic stress disorder. Rather, the findings point to cerebral abnormalities that may reflect the influence of early trauma on neurodevelopmental processes or denote brain morphometric characteristics of persons at increased risk for serious psychosocial adversity.

Neuropsychological function in female victims of intimate partner violence with and without posttraumatic stress disorder.

BACKGROUND: Various aspects of neuropsychologic function have been reported to be abnormal in patients with posttraumatic stress disorder (PTSD); however, the majority of these data come from studies of seriously ill, treatment-seeking samples with substantial substance use comorbidity. Few studies have included similarly trauma-exposed subjects without PTSD, and fewer still have focused on women. METHODS: Thirty-nine female victims of intimate partner violence (IPV; 22 without lifetime PTSD and 17 with current PTSD), and 22 nonvictimized comparison (NC) subjects were administered tests of attention, working memory, visuoconstruction, language ability, learning and memory, and executive functioning. RESULTS: The IPV and NC subjects did not demonstrate statistically significant differences on most neuropsychologic tests, with the exception of those in the realm of working memory, visuoconstruction, and executive functioning. The IPV subjects, regardless of PTSD status, had poorer performance on tasks of speeded, sustained auditory attention and working memory (Paced Auditory Serial Addition Test) and response inhibition (Stroop). The IPV subjects with PTSD performed worse than NCs on a set-shifting task (Trail Making Test, Part B). No consistent relationships were noted between neuropsychologic functioning and severity of childhood abuse or domestic violence experiences. CONCLUSIONS: Cognitive deficits in IPV subjects were confined to measures of working memory, visuoconstruction, and executive function; were subtle; and were not uniformly worse among those with current PTSD. This pattern, however, is consistent with frontal-subcortical dysfunction in traumatized women. The clinical significance of these findings deserves further study.

Anxiety sensitivity and PTSD among female victims of intimate partner violence.

The purpose of this study was to evaluate the relationship between anxiety sensitivity (AS) and posttraumatic stress disorder (PTSD) in women. The study involved three groups: women with no history of exposure to serious trauma (n = 30), women who had been exposed to intimate partner violence (IPV) but never developed PTSD (n = 23), and women with IPV exposure and current PTSD (n = 19). As a part of a larger study, they completed measures of AS, PTSD symptomatology, and depression. Women with PTSD reported the highest levels of AS, although traumatized women with PTSD reported more AS than did women with no trauma history. AS-related psychological concerns were a statistical predictor of PTSD symptoms when the entire sample of women was considered but not among the subset with a trauma history. Nonetheless, AS may be an important factor to consider in treatment of individuals with PTSD.
