Knowledge about human papillomavirus among adolescents.

OBJECTIVE: To assess knowledge of human papillomavirus (HPV) among high school-aged adolescents. METHODS: We administered written surveys to 523 inner-city high school students in Toronto, Canada, that asked about HPV, other sexually transmitted diseases (STDs), and Papanicolaou testing. We also asked them to report doctor or clinic visits and whether they received sexual health information at those visits. The predictor variables used in analysis were gender and sexual experience. RESULTS: Eighty-seven percent of our population [95% confidence interval (CI) 84%, 89%) had not heard of HPV. Although adolescent women were more knowledgeable about Papanicolaou testing than adolescent men, only 39% of sexually experienced adolescent women knew who should get a Papanicolaou test. Sexually experienced and inexperienced adolescents failed to identify correctly their STD risk. Both genders showed greater knowledge about human immunodeficiency virus (HIV) than other diseases. Among adolescent women, 85% had visited a doctor or clinic within the past year, but only 29% had talked about sexual health. CONCLUSION: Knowledge of HPV infection and cervical cancer screening was low in this urban adolescent population. Improved efforts are needed for prevention of HPV infection and HPV-related cervical changes. Programs modeled after HIV-education programs might be effective. Doctors' offices and clinics providing health care to adolescents should take greater responsibility in sexual health education.

Women physicians and stress.

Most women physicians enjoy better than average physical health and lead satisfying and productive lives. However, higher than average rates of depression, anxiety, marital problems, and substance abuse have been reported by some, but not all, authors. This quantitative survey of 196 women physicians and qualitative focus groups with 48 other women physicians was conducted to determine perceptions of their health, stress, satisfaction, knowledge, and abuse rates in medical practice. Eight specialties plus family practice physicians participated. The average age was 44.1 years (SD 8.8, range 23-77). Seventy-four percent of women physicians were married, with children. Specialists and family physicians were similar in all demographic characteristics except that family physicians were more significantly likely to be divorced, separated, or widowed (p < or = 0.01). Specialists perceived their personal physical health to be better than that of family doctors (p < or = 0.05), and family physicians rated their medical knowledge better than that of specialists (p < or = 0.0001). Women physicians over age 50 or with children over age 19 reported the best mental health (p < or = 0.0001 and 0.003, respectively). Overall, 49% of women physicians reported usually having high levels of stress, 44% felt mentally tired, and 17% took antidepressant drugs. Seventy-three percent reported verbal abuse at work (71% in the last year), and 33% reported physical assault at work (11% in the last year). Focus groups identified three major sources of stress: high expectations, multiple roles, and work environment. These results are discussed and compared with the literature. Both personal and systemic strategies are required to solve the problems identified. Women physicians can facilitate the adoption of some of these strategies by sharing information about successes, challenges, and solutions.

Antidepressant drugs during pregnancy and lactation.

As depression is common in women during their childbearing years, many women will experience depression during pregnancy or postpartum. This paper reviews the latest scientific knowledge on the effects of antidepressant drugs during pregnancy and lactation. Information is presented on physical and behavioural teratogenic risks, impaired intrauterine growth, and neonatal toxicity, withdrawal, and death. Risk : benefit considerations, such as the effects of antidepressant drugs on the mother and foetus compared with the effects of untreated severe depression, are discussed to facilitate clinical decision-making. Recent studies of the safety of antidepressant drugs during pregnancy and lactation are predominantly reassuring, and should guide and improve the care of depressed childbearing women and their infants.

Use of hormone replacement therapy among cardiac patients at a Canadian academic centre.

BACKGROUND: Although hormone replacement therapy (HRT) is associated with a reduced risk of coronary artery disease (CAD), use of this treatment among post-menopausal women is not widespread. The authors sought to determine the extent of HRT use in a select population of women at high risk for CAD. METHODS: A cross-sectional survey was performed involving all consecutive post-menopausal women who attended a cardiology clinic in a Toronto teaching hospital between January 1996 and August 1997. A chart review was followed by a telephone interview with the patients or their physicians. The utilization rate of HRT was obtained. Predictors of HRT use were identified using a multivariate logistic regression model. RESULTS: A total of 80 women with risk factors for CAD, symptoms suspicious of CAD or definite CAD diagnosed after cardiac investigations were included in the survey. Information on HRT use or nonuse was documented in 17 (21%) of the charts. Of the 72 women for whom data on HRT were available 16 (22%) were currently using it, 41 (57%) were not, and 15 (21%) had used it in the past. Five women (7%) were receiving HRT but there was no chart documentation. On multivariate analysis, younger women were more likely than older women to use HRT (odds ratio 0.91, 95% confidence interval 0.22-0.96; p < 0.05). Coronary risk profile, CAD diagnosis and history of hysterectomy were not associated with HRT use. Of the 41 women who had never received HRT 10 (24%) had possible contraindications (e.g., breast cancer or deep vein thrombosis); the proportion was similar in the group of women who were current or past users of HRT (29%). INTERPRETATION: Documentation of HRT use in patient charts is lacking. Few women in the study who were at risk for CAD were currently using HRT. The data support the need for better adherence to optimal practices in the management of women at high risk for CAD.

Is premenstrual dysphoric disorder a distinct clinical entity?

Does the evidence now available support the concept of premenstrual dysphoric disorder (PMDD) as a distinct clinical disorder such that the relative safety and efficacy of potential treatment can be evaluated? In a roundtable discussion of this question, a wealth of information was reviewed by a panel of experts. The key characteristics of PMDD, with clear onset and offset of symptoms closely linked to the menstrual cycle and the prominence of symptoms of anger, irritability, and internal tension, were contrasted with those of known mood and anxiety disorders. PMDD displays a distinct clinical picture that, in the absence of treatment, is remarkably stable from cycle to cycle and over time. Effective treatment of PMDD can be accomplished with serotinergic agents. At least 60% of patients respond to selective serotonin reuptake inhibitors (SSRIs). In comparison with other disorders, PMDD symptoms respond to low doses of SSRIs and to intermittent dosing. Normal functioning of the hypothalamic-pituitary-adrenal (HPA) axis, biologic characteristics generally related to the serotonin system, and a genetic component unrelated to major depression are further features of PMDD that separate it from other affective (mood) disorders. Based on this evidence, the consensus of the group was that PMDD is a distinct clinical entity. Potential treatments for this disorder can now be evaluated on this basis to meet the clear need for effective therapy.

Patient preference for the management of mildly abnormal Papanicolaou smears.

Our objective was to investigate patient knowledge, desire for participation in medical decision making, and preference for the management of mildly abnormal Papanicolaou (Pap) smears (low-grade squamous intraepithelial lesions [LGSIL]) in the context of the continuing controversy between active (immediate colposcopy and biopsy) and surveillance (repeat Pap smears) management strategies. One hundred thirty-six women referred for a diagnostic colposcopy with a first-time mildly abnormal Pap smear result completed questionnaires before contact with either the nurse or physician. They were given the State-Trait Anxiety Inventory, the CESD Depression scale, and a knowledge about dysplasia quiz. They were then presented with the two management options and asked to state a preference, if any. They then completed the Problem Solving-Decision Making Scale, a measure of desire for involvement in medical decision making. The majority of women in this sample opted for the active management strategy. Management preference was related to anxiety, with the most anxious women more likely to choose the active management strategy. Management preference was not related to knowledge or to desire for an active role in decision making, although the more knowledgeable women also reported a desire for an active role in the decision-making process. Given the current controversy over the management of mildly abnormal Pap smears (LGSIL), as well as the fact that there is no conclusive evidence to support one strategy over another, the informed management preference of women affected by these decisions should be factored into the equation.

Parameters of grieving in spontaneous abortion.

OBJECTIVE: The study's objective was to determine the quality and severity of grief after spontaneous abortion and to statistically determine the effect of significant demographics and social variables such as age, number of previous losses and the effect of perceived family support on the grief experienced. METHODS: Two hundred and ninety-four women who had experienced a miscarriage within the last year were the participants. One hundred and seventy-five had miscarried three months prior to participation in the study; one hundred and nineteen had miscarried one year previously. Ninety-five percent of women approached consented to participate. Standardized psychometric tests and Likert Scales measured elements of grief such as depression, self-esteem, perceived guilt and stress at two time periods in the first year after loss. RESULTS: Women in both time periods after miscarriage had mean depression scores in the "clinical risk for depression" or "in need of treatment" range, i.e., pharmacotherapy or psychotherapy. A majority of women showed negative emotions like self blame and stress. Younger women with multiple miscarriages showed more depression in the early time period after miscarriage than older women (p < .05). However, at one year younger women had the least depression. Marital and family conflict correlated positively with depressive symptomatology (p < .05). CONCLUSIONS: Women assessed in the first year after spontaneous abortion show grief characterized by perceived stress and high levels of depressive symptoms including self-blame. Marital or family problems increase emotional risk to a woman after miscarriage.

Using the ALPHA form in practice to assess antenatal psychosocial health. Antenatal Psychosocial Health Assessment.

BACKGROUND: The assessment of the psychosocial health of pregnant women and their families, although recommended, is not carried out by most practitioners. One reason is the lack of a practical and evidence-based tool. In response, a multidisciplinary group created the Antenatal Psychosocial Health Assessment (ALPHA) form. This article describes the development of this tool and experience with it in an initial field trial. METHODS: A systematic literature review revealed 15 antenatal psychosocial risk factors associated with poor postpartum family outcomes of woman abuse, child abuse, postpartum depression, marital/couple dysfunction and increased physical illness. The ALPHA form, incorporating these risk factors, was developed and refined through several focus groups. It was then used by 5 obstetricians, 10 family physicians, 7 midwives and 4 antenatal clinic nurses in various urban, rural and culturally diverse locations across Ontario. After 3 months, these health care providers met in focus groups to discuss their experiences. A sample of pregnant women assessed using the ALPHA form were interviewed about their experience as well. Results were analysed according to qualitative methods. RESULTS: The final version of the ALPHA form grouped the 15 risk factors into 4 categories--family factors, maternal factors, substance abuse and family violence--with suggested questions for each area of enquiry. The health care providers uniformly reported that the form helped them to uncover new and often surprising information, even when the women were well known to them. Incorporating the form into practice was usually accomplished after a period of familiarization. Most of the providers said the form was useful and would continue to use it if it became part of standard care. The pregnant women in the sample said they valued the enquiry and felt comfortable with the process, unless there were large cultural barriers. INTERPRETATION: The ALPHA form appears to be an important tool in assessing psychosocial health in pregnancy and to be readily integrated into practice. More study is required to quantify the number of risks identified and resources used, to determine the form's reliability and validity and, ultimately, to assess the effect of its use on postpartum outcomes.

Psychotherapy with a woman at high risk for developing breast cancer.

Women who are at high risk for developing breast cancer increasingly consult with psychiatrists about the psychological, social, and sexual consequences of genetic testing and risk-reducing surgeries such as bilateral mastectomy and oophorectomy. The 9-year psychotherapy with a woman who had bilateral mastectomy because of her family history of breast cancer and who later tested negative for BRCA1 is described and discussed.

Fatigue in primary biliary cirrhosis.

BACKGROUND: Fatigue is a frequent and debilitating symptom in patients with primary biliary cirrhosis (PBC). AIMS: To study fatigue in relation to sleep, depression, and liver disease severity. METHODS: Patients with PBC completed validated self report questionnaires measuring fatigue, sleep quality, depression, and functional capacity. Verbally reported fatigue and observer rated measure of depression and ursodeoxycholic acid (UDCA) use were recorded. Liver biochemistry and tests to rule out metabolic causes of fatigue were performed. RESULTS: Mean age of the 88 patients enrolled was 57 years; 86% were female and mean duration of disease was 6.6 years. Median bilirubin was 13 micromol/l (mean 18.6). Verbally reported fatigue (for more than six months) was present in 60 patients (68%). The self rated Fatigue Severity Score (FSS) correlated well with verbally reported fatigue (p=0.0001). The FSS did not correlate with age, duration of disease, serum bilirubin, Mayo Risk Score, or UDCA use, but correlation was seen with sleep quality. Fatigued patients had more sleep problems and higher depression scores than non-fatigued patients. Self rated depression was present in 28% (17/60) of fatigued compared with 4% (1/28) of non-fatigued patients. CONCLUSIONS: Long term fatigue affected 68% of the patients with PBC but it was not related to the severity of their liver disease. Poor sleep quality and depression were commonly associated with fatigue.

Are there special considerations in the prescription of serotonin reuptake inhibitors for women?

OBJECTIVE: To present information on special considerations in the prescription of selective serotonin reuptake inhibitor (SSRI) antidepressant drugs to women. METHODS: Literature review and analysis of adverse drug reactions to SSRIs reported to Health Canada between 1986 and 1996. RESULTS: SSRIs are prescribed twice as often to women as to men. Special considerations are required of the social context in which the illness occurs, biological aspects of the illness, the effects of endogenous and exogenous sex steroids, menstruation, pregnancy, lactation, and menopause. Serious or fatal side effects are most commonly drug-drug or drug-alcohol interactions, and endocrine side effects are more common in women than men. CONCLUSIONS: Although SSRIs are relatively effective and safe when prescribed to women, further research is required for long-term follow-up of children exposed to these drugs in utero or during lactation. Continued study of the effects of sex steroids on pharmacodynamics and kinetics and ongoing monitoring and reporting of side effects in women is required. Special consideration of endocrine side effects and drug-drug and drug-alcohol interactions are needed for optimal safety.

Survey of parental-leave policies and experiences in Ontario academic departments of psychiatry.

OBJECTIVE: To analyze psychiatrists' self-reports on a survey of faculty parental leaves conducted in 5 Ontario faculties of medicine. METHOD: A self-report questionnaire was mailed to all Ontario academic medical faculty members requesting information on demographics, parenting status, knowledge of parental-leave policies, personal and collegial experience of recent parental leave, and opinions about ideal parental-leave policies. RESULTS: The survey yielded a 48.6% response rate (3104 respondents). Of the respondents, 318 (10.2%) were academic psychiatrists and 113 (35.5%) of them had or adopted children since 1990. Of the 113 recent parents, 59 (53.2%) did not know their official university parental-leave policy. Fifty-one (48.1%) psychiatrists had recently taken parental leave (30 female, 21 male). Of these, females (26, 86.7%) were more likely than males (0%) to take more than 8 weeks' leave (P = 0.001). The income paid during parental leave was highly variable. Although 192 (64.4%) psychiatrists recommended that temporary replacements be hired and 175 (59.1%) recommended that the replacements be paid from a common faculty risk pool, replacements were hired for only 7 (13.7%) recent leaves. This replacement rate for psychiatry parental leaves was the second lowest of 8 medical specialties. Several leave takers felt that the leave negatively affected their research (32, 32.7%), administration (24, 23.3%), overall career course (23, 21.5%), colleagues' workload (27, 26.2), clinical work (19, 18.3%), teaching (18, 17.3%) and colleagues' attitudes toward them (11, 10.4%). Although 220 (71.5%) academic psychiatrists recommended paid leave to the primary caregiver for 16 or more weeks, 88 (28.6%) recommended less than the 17-week national standard. For secondary caregivers, 202 (66.0%) academic psychiatrists recommended a paid leave of 1-8 weeks, but 63 (20.6%) recommended paid leave for less than 1 week. One hundred and fifty-four psychiatrists (53.1%) recommended that parental-leave income be composed of usual income excluding clinical earnings, a less generous recommendation than that suggested by academic physicians in family medicine, pediatrics, internal medicine, and surgery. CONCLUSIONS: The lack of knowledge of parental-leave policies and the variability in income and duration of parental leaves among Ontario academic psychiatrists call for the development, transmission, and implementation of equitable policies. Common faculty risk pools should be established to pay temporary replacements for parental leaves to facilitate the hiring of replacements and to avoid overburdening remaining colleagues. Strategies to allow new parents to continue their career development, especially in research, need further attention. There are clear discrepancies between what psychiatrists believe to be the vital role of early parenting in child development and what they recommend and provide with regard to parental leave for their colleagues. These discrepancies become more evident when compared with the more generous policies and practices in several other medical specialties.

Alternative treatments for menopausal symptoms. Qualitative study of women's experiences.

OBJECTIVE: To describe women's experiences with alternative treatments for symptoms attributed to menopause. DESIGN: Descriptive qualitative study. SETTING: Personal interviews and focus groups were conducted in private rooms at the Toronto Hospital; telephone interviews were conducted at mutually convenient times. PARTICIPANTS: Thirteen perimenopausal women with a mean age of 52.6 +/- 2.6 years who were experiencing symptoms attributed to menopause and were using alternative therapies participated in the study. METHOD: Women using alternative therapies for menopausal symptoms were recruited via posted notices and were screened over the telephone. Data were collected during semistructured personal interviews, telephone interviews, and a focus group. All interviews were audiotaped, transcribed, and mailed to participants for verification. Recruitment continued until theme saturation was reached. MAIN FINDINGS: Because of their "natural" origin, the women perceived alternative treatments to be safe and considered them somewhat effective. Factors influencing use of alternative therapies included personal control over health, confidence in advice from nonphysicians, perceived pressure from physicians to use hormone replacement therapy, and physicians' disinterest and frequently negative attitudes toward alternatives. CONCLUSION: Personal control was a central issue. Helping women during their menopausal years feel they have some control over their health, including their informed choice of treatments, might help them to trust their physicians more and to feel more confident in their ultimate treatment decisions, which might include improvements in health behaviour.

Alternative treatments for menopausal symptoms. Systematic review of scientific and lay literature.

OBJECTIVE: To review the scientific literature on common alternative remedies for treatment of symptoms attributed to menopause and to contrast this with available lay literature. QUALITY OF EVIDENCE: Scientific articles were identified by searching MEDLINE, CINAHL, and HEALTH databases from 1966 to mid-1997 for English-language articles. More than 200 references were reviewed; 85 were selected for citation based on specific reference to alternative medicine for symptoms commonly attributed to menopause (e.g., hot flashes), to the effects of changing estrogen levels (e.g., irregular menses, vaginal dryness), and to reported side effects of the treatments. MAIN FINDINGS: The scientific literature was categorized under the headings nutritional supplements, herbal remedies, homeopathic remedies, and physical approaches. Some scientific evidence of the safety and efficacy of alternative treatments during menopause was uncovered, with the strongest evidence emerging in favour of phytoestrogens, which occur in high concentrations as isoflavones in soy products. CONCLUSIONS: In available controlled studies, the strongest data support phytoestrogens for their role in diminishing menopausal symptoms related to estrogen deficiency and for possible protective effects on bones and the cardiovascular system. Randomized controlled trials, standardization of dosage, and accurate safety and efficacy labeling are required to ensure proper use of alternative remedies.
