A comparison of TC7 and 32% dextran 70 for prevention of postoperative adhesions in hamsters.

Prevention of postoperative adhesion formation has received considerable attention by infertility specialists. Barrier methods and hydroflotation solutions are currently used for adhesion prevention. The present study compared the efficacy of TC7 and 32% dextran 70 in a hamster model. At laparotomy, 90 golden hamsters had a lesion created on the left uterine horn and repaired with absorbable suture. The first experiment used 3-0 chromic catgut suture in 43 hamsters; the second experiment used 5-0 polyglactin 910 suture in 47 hamsters. The animals were randomly divided into a control group (N = 25) which received no treatment, a TC7-treated group (N = 33), and a 32% dextran 70-treated group (N = 32). The animals were sacrificed between 10-14 days after laparotomy and adhesions were graded (0 = no adhesions; 3 = severe adhesions). TC7 had average adhesion scores of 1.91 for chromic catgut and 2.25 for polyglactin 910; 32% dextran 70 had average adhesion scores of 1.53 and 2.00, respectively. These scores were not different from the control average adhesion score of 1.80 for both chromic catgut and polyglactin 910. We conclude that TC7 and 32% dextran 70 do not appear to be effective agents for preventing postoperative adhesions in this animal model.

Modulation of human granulosa cell steroid production in vitro by tumor necrosis factor alpha: implications of white blood cells in culture.

OBJECTIVE: To test the hypothesis that the macrophage cytokine, tumor necrosis factor-alpha (TNF-alpha), directly inhibits progesterone, estrone (E1), and estradiol (E2) synthesis by human granulosa cells in vitro in the presence and absence of white blood cells. METHODS: Granulosa cells from follicle aspirates of patients undergoing in vitro fertilization (IVF) were separated from red blood cells on 50% Percoll columns. Such preparations contained numerous white blood cells (lymphocytes, 40-52%, and macrophages, 6-14%) as determined with immunocytochemistry. In some studies, anti-CD45 magnetic beads followed by an additional adherence step and media change were used to remove white blood cells from granulosa cell cultures. Granulosa cells with and without associated white blood cells were cultured in basal and hCG-supplemented media. Androstenedione (40 ng/mL) and/or recombinant TNF-alpha (0.5-50 ng/mL) were added to triplicate wells. Media were harvested for radioimmunoassay of progesterone, E1, and E2 after 24 and 48 hours of incubation. RESULTS: The effects of TNF-alpha on progesterone production in white blood cell-associated cultures were inconsistent when 0.5 ng/mL TNF-alpha was added under basal conditions. At higher TNF-alpha doses (5-50 ng/mL) and under hCG-stimulated conditions, there was a consistent decrease in progesterone production, but the effect was not clearly dose-dependent. It was possible to remove white blood cells effectively from granulosa cell cultures. In granulosa cell cultures without associated white blood cells, 0.5 ng/mL of TNF-alpha at 48 hours produced an increase in progesterone, whereas 50 ng/mL of TNF-alpha decreased progesterone (P < .001). Estrone and E2 were both decreased by TNF-alpha regardless of whether white blood cells were present in culture, without clear evidence of dose-dependency. Granulosa cell viability and proliferation were unaffected by TNF-alpha as demonstrated by direct cell counts, trypan blue exclusion, and tetrazolium salt viability assays. CONCLUSIONS: In the normal ovary, TNF-alpha may influence the development of the dominant follicle by inhibiting aromatase activity. It may also mediate oocyte maturation disorders and ovarian endocrine dysfunction in some pathologic states. White blood cells can be effectively removed from granulosa cell cultures. Application of this removal technique will facilitate future granulosa cell studies by allowing more precise determination of direct granulosa cell function.

Unexplained displacement of ipsilateral ovary and fallopian tube.

During routine laparoscopy, the right fallopian tube and ovary were noted to be displaced. Ovarian and fallopian tube tissue were found on biopsy of adjacent omentum. The most probable cause is asymptomatic torsion of the right adnexum; therefore, evaluation of the renal system with intravenous pyelogram is probably not necessary.

The reproducibility of the postcoital test: a prospective study.

OBJECTIVE: To determine the reproducibility of the postcoital test among trained observers. METHODS: Twenty-eight infertile patients presenting to the Brigham and Women's Hospital over a 1-year period were recruited for the study. After a standardized collection of specimens for the postcoital test, four fellowship-trained reproductive endocrinologists evaluated six postcoital test characteristics and gave their overall impression of the test. Each observer was blinded to the patients' identities and clinical histories as well as to the ratings of the other observers. The six characteristics included an assessment of the cervical mucus by ferning, cellularity, spinnbarkeit, and consistency, and of sperm by total count per high power field and percent motility. Scoring was adapted from World Health Organization (WHO) criteria for semen-cervical mucus interaction. Statistical analysis included the kappa statistic to determine agreement among observers for postcoital test characteristics and the Mantel-Haenszel test to determine the association between overall impression and the other test characteristics. RESULTS: Agreement among the four observers was best for sperm number and motility (39% of cases) and worst for cellularity, spinnbarkeit, and overall test impression (11, 14, and 14% of cases, respectively). The kappa statistic ranged from a low of 0.13 for cellularity, demonstrating poor reliability (95% confidence interval [CI] 0.03-0.23), to a high of 0.51 for sperm number, demonstrating fair reliability (95% CI 0.41-0.60). Only sperm number and percent motility were significantly associated with the overall impression (P < .001). CONCLUSIONS: In a blinded study, the characteristics of the postcoital test were found to have poor to fair reproducibility among trained observers using a standardized WHO scoring system. The observers' overall impressions of test quality correlated with sperm number and motility only. We question the validity of the postcoital test as a diagnostic tool in the evaluation of infertility.

Predictors of post-rape medical care in a national sample of women.

BACKGROUND: Rape has a negative impact on physical and mental health, health-related behaviors, and health service utilization. Timely medical care is important for preventive services. METHODS: Cross-sectional data were obtained from a larger 2-year longitudinal study, the National Women's Study (NWS). A total of 3006 adult women participated in the final data collection wave of the NWS. During a structured telephone interview, women who reported a most-recent or only rape incident during adulthood were asked about rape characteristics, reporting to authorities, medical care, and rape-related concerns. The main outcome measures were receipt and timing of medical care received after an adult rape, and factors influencing whether or not medical care was received. RESULTS: Of the sample, 214 (7.1%) had experienced a most-recent or only rape as an adult (aged >/=18), and 56 (26.2%) received rape-related medical care following that incident. The final model multivariable logistic regression indicated that reporting the crime to police or other authorities (odds ratio [OR], 9.45; 95% confidence interval [CI]=3. 34-26.70) and fear of sexually transmitted diseases (OR, 8.61; 95% CI=3.12-23.72) were significant predictors of receipt of post-rape medical care. CONCLUSIONS: One in five victims reported an adult rape to police or other authorities; these women were nine times more likely to receive medical care than those who did not. Public health efforts are needed to increase the proportion of rape victims who receive immediate post-rape medical care.

Fixed cutaneous eruptions to seminal-plasma challenge: a case report.

Reactions to human seminal plasma may present as immediate hypersensitivity, cell-mediated hypersensitivity, or fixed eruptions. There are no typical responses to semen. An abnormal skin lesion or systemic response after intercourse may be the only clue to identifying those who are reacting to semen. The use of condoms has proven to be the most consistent preventive modality. However, the use of condoms is unacceptable to some regardless of the relief provided. Although conventional therapy for hypersensitivity reactions to human seminal plasma is suboptimal, one should be aware of MA in the treatment of an atypical cause of human seminal plasma induced reactions.

Evaluation of interceed(TC7) for reduction of postoperative adhesions in rabbits.

OBJECTIVE: To evaluate the effectiveness of Interceed(TC7) (Johnson and Johnson, New Brunswick, NJ) in the prevention of postoperative adhesions in a rabbit uterine horn model. Interceed(TC7) was tested in the presence and absence of absorbable suture. DESIGN, SETTING, PARTICIPANTS: Forty-one New Zealand white rabbits had lesions created on bilateral uterine horns at laparotomy. Lesions were randomly allocated to treatment with Interceed(TC7) or control. The effect of Interceed(TC7) was evaluated on sutured lesions (4-0 polyglactin 910; Ethicon, Inc., Somerville, NJ) as well as on open cut lesions (no sutures applied). MAIN OUTCOME MEASURES: Adhesion formation, using a grading system ranging from 0 to 3. RESULTS: Interceed(TC7)-treated animals in the sutured group (average adhesion score +/- SD = 2.15 +/- 1.3) did not differ from controls (average score +/- SD = 2.35 +/- 0.93) in adhesion formation, P = 0.47. Rabbits with open cut lesions treated with Interceed(TC7) (average adhesion score +/- SD = 1.89 +/- 1.1) did not differ from control animals (average score +/- SD = 1.83 +/- 1.2), P = 0.88. CONCLUSIONS: Interceed(TC7) was not an effective adhesioprophylactic agent in the presence or absence of nonreactive absorbable suture.

Prevalence of civilian trauma and posttraumatic stress disorder in a representative national sample of women.

Prevalence of crime and noncrime civilian traumatic events, lifetime posttraumatic stress disorder (PTSD), and PTSD in the past 6 months were assessed in a sample of U.S. adult women (N = 4,008). Random digit-dial telephone methods were used to identify study participants. Structured telephone interviews for assessment of specific crime or other traumatic event history and PTSD were conducted by trained female interviewers. Lifetime exposure to any type of traumatic event was 69%, whereas exposure to crimes that included sexual or aggravated assault or homicide of a close relative or friend occurred among 36%. Overall sample prevalence of PTSD was 12.3% lifetime and 4.6% within the past 6 months. The rate of PTSD was significantly higher among crime versus noncrime victims (25.8% vs. 9.4%). History of incidents that included direct threat to life or receipt of injury was a risk factor for PTSD. Findings are compared with data from other epidemiological studies. Results are discussed as they relate to PTSD etiology.

Risk factors for adolescent substance abuse and dependence: data from a national sample.

A national household probability sample of 4,023 adolescents aged 12 to 17 years was interviewed by telephone about substance use, victimization experiences, familial substance use, and posttraumatic reactions to identify risk factors for Diagnostic and Statistical Manual of Mental Disorders--(4th ed.; American Psychiatric Association, 1994) defined substance abuse/dependence. Age and ethnicity data were available for 3,907 participants. Major findings were (a) adolescents who had been physically assaulted, who had been sexually assaulted, who had witnessed violence, or who had family members with alcohol or drug use problems had increased risk for current substance abuse/dependence; (b) posttraumatic stress disorder independently increased risk of marijuana and hard drug abuse/dependence; and (c) when effects of other variables were controlled, African Americans, but not Hispanics or Native Americans, were at approximately 1/3 the risk of substance abuse/dependence as Caucasians.

A 2-year longitudinal analysis of the relationships between violent assault and substance use in women.

Women experience alarming levels of physical and sexual assault, which may lead to escalation of substance use. Reciprocally, evidence from cross-sectional studies indicates that substance use may increase risk of assault. To date, directionality of this relationship remains unclear. This issue is addressed by the present 3-wave longitudinal study in which a national probability sample of 3,006 women were followed for 2 years. Dependent measures were obtained at each wave of the study and included questions about lifetime and new assault status, alcohol abuse, and drug use. Wave 1 use of drugs, but not abuse of alcohol, increased odds of new assault in the subsequent 2 years. Reciprocally, after a new assault, odds of both alcohol abuse and drug use were significantly increased, even among women with no previous use or assault history. For illicit drug use, findings support a vicious cycle relationship in which substance use increases risk of future assault and assault increases risk of subsequent substance use.

The socioeconomic impact of interpersonal violence on women.

Prospective data from a nationally representative sample of women were used to examine 4 objective indexes of social adjustment following direct, interpersonal crime. Household income, marital status, employment, and education level were evaluated as risk factors for and outcomes of victimization. Data were collected in 3 waves at 1-year intervals, and 2,863 women completed all 3 waves. Results indicate that women experience increased risk for victimization when income is below poverty level and when newly divorced. Further, victimization appears to increase women's risk for unemployment, reduced income, and divorce. The cyclical nature of victimization is discussed.

Self-destructive behavior in hospitalized medical and surgical patients.

This article reviews the literature and presents data from the Psychiatric Consultation Service of the Medical University of South Carolina on self-destructive behavior in hospitalized medical and surgical patients. Fatal suicide attempts are rare and usually occur in patients with severe, painful chronic illnesses, psychosis, or dementia. Less overt forms of self-destructive behavior include refusal of medical treatment and uncooperative behavior.

Risk factors for rape, physical assault, and posttraumatic stress disorder in women: examination of differential multivariate relationships.

The National Women's Study, a 2-year, three-wave longitudinal investigation, employed a national probability sample of 3,006 adult women to: (a) identify separate risk factors for rape and physical assault, and (b) identify separate risk factors associated with post-rape posttraumatic stress disorder (PTSD) and post-physical assault PTSD. This investigation differed from previous studies in that it prospectively examined risk factors at the multivariate, as opposed to univariate level. Overall, past victimization, young age, and a diagnosis of active PTSD increased women's risk of being raped. By contrast, past victimization, minority ethnic status, active depression, and drug use were associated with increased risk of being physically assaulted. Risk factors for PTSD following rape included a history of depression, alcohol abuse, or experienced injury during the rape. However, risk factors for PTSD following physical assault included only a history of depression and lower education.

Delay in disclosure of childhood rape: results from a national survey.

OBJECTIVE: This study sought to gather representative data regarding the length of time women who were raped before age 18 delayed prior to disclosing such rapes, whom they disclosed to, and variables that predicted disclosure within 1 month. METHOD: Data were gathered from 3,220 Wave II respondents from the National Women's Study (Resnick, Kilpatrick, Dansky, Saunders, & Best, 1993), a nationally representative telephone survey of women's experiences with trauma and mental health. Of these, 288 retrospectively reported at least one rape prior to their 18th birthday. Details of rape experiences were analyzed to identify predictors of disclosure within 1 month. RESULTS: Fully 28% of child rape victims reported that they had never told anyone about their child rape prior to the research interview; 47% did not disclose for over 5 years post-rape. Close friends were the most common confidants. Younger age at the time of rape, family relationship with the perpetrator, and experiencing a series of rapes were associated with disclosure latencies longer than 1 month; shorter delays were associated with stranger rapes. Logistic regression revealed that age at rape and knowing the perpetrator were independently predictive of delayed disclosure. CONCLUSIONS: Delayed disclosure of childhood rape was very common, and long delays were typical. Few variables were identified that successfully predicted disclosure behavior, but older age and rape by a stranger were associated with more rapid disclosure. This suggests that the likelihood of disclosure in a given case is difficult to estimate, and predictions based on single variables are unwarranted.

Violent assault, posttraumatic stress disorder, and depression. Risk factors for cigarette use among adult women.

Cigarette smoking may be conceptualized as a strategy to cope with negative affect. Therefore, rates of cigarette use might be expected to be greater in individuals experiencing events that produce negative affect, such as assault. To test this hypothesis, a national sample of 3,006 women aged 18 and older was assessed for lifetime and current cigarette use, previous history of physical and sexual assault, lifetime and current incidence of depression, and lifetime and current incidence of PTSD. Results indicated that the odds of active smoking in women with a lifetime history of assault were 1.82 times those of women with no previous history of assault. Similarly, risk of active cigarette use in women with a previous history of depression or PTSD was 2.22 and 1.34 times those of women with no depressive or PTSD history, respectively. Recent assault, current PTSD, or current depression status were not associated with increased cigarette use.

Predictors of medical examinations following child and adolescent rapes in a national sample of women.

Childhood rape occurs frequently in our society and is associated with adverse consequences. Despite the severity of these outcomes, there appear to be many obstacles for children to receive postrape medical care. To date, it is unclear what proportion of childhood rape victims receive postrape medical examination or what factors predict receipt of this medical care. This study instigated the factors predicting immediate medica care for women who were raped during childhood. Data for the study were obtained from the final wave of the 2-year, longitudinal National Women's Study. Results indicated that the majority of women did not receive medical care following their childhood rape. Although women raped as adolescents were more likely to receive a postrape exam, logistic regression analyses indicated that rape characteristics (e.g., reporting the assault, concerns about sexually transmitted diseases [STDs]) mediated the relationship between age of victimization and receipt of medical care. Implications of these findings are discussed.
