Estrogen replacement therapy and female athletes: current issues.

Physicians commonly recommend estrogen replacement as treatment for exercise-associated amenorrhoea. While the evidence shows that the basis of the amenorrhoea is estrogen deficiency, it is not clear that it is the only factor in the development of lowered bone density found in oligo-amenorrhoeic female athletes. Nutritional factors, significant in the development of the reproductive dysfunction, could also contribute to bone loss. No randomised, controlled studies of estrogen replacement in athletes have been published. However, one nonrandomised study of a small group of athletes does suggest that there are significant gains in bone density to be made by the initiation of estrogen therapy. More research is clearly needed.

Tamoxifen in breast cancer: symptom reporting.

Clinical studies have traditionally identified treatment-specific side effects by comparison of voiced side effects in treatment and placebo arms of a study. Highly motivated women in a clinical trial may underreport drug-induced symptoms for medications which may be considered lifesaving. Affective symptoms during treatment of early breast cancer with tamoxifen (an estradiol receptor antagonist) were reported as infrequent by the manufacturer. However, reports suggest a higher rate of depression during general use. The objective of the present study was to examine the frequency of symptoms that might be side effects of tamoxifen and to relate them to the way the women attributed such symptoms. The exploratory study involved semistructured telephone interviews of 25 women who were taking tamoxifen. Textual analysis of the information was used to examine the symptoms described by the women. They were also asked whether any symptoms were related to the medication. The symptoms and their attribution were evaluated against a background of self-perceived stress. The principal finding was a pattern of ambivalence in attributing symptoms to the drug. Of all the symptomatic changes noted, the women only attributed 51% to tamoxifen. Flushes, fatigue, and depression were reported most frequently during treatment; flushes were readily attributed to tamoxifen but depression and fatigue were attributed to another factor by half of the symptomatic women. Women who reported moderate to high levels of life stress were less likely to attribute symptoms to drug therapy. The results suggest that women taking tamoxifen may not attribute known drug side effects to use of the medication.

Psychological well-being and coping patterns in infertile men.

OBJECTIVE: To determine whether differences existed in mood and coping styles among fertile men, oligoasthenospermic men, or euspermic men whose wives were undergoing ovulation stimulation with clomiphene and IUI. DESIGN: A cross-sectional research design. SETTING: Hospital-based academic fertility clinic. PATIENT(S): 30 fertile men with currently pregnant wives, 30 euspermic and 30 oligoasthenospermic men in couples undergoing ovulation stimulation with clomiphene and IUI. INTERVENTION(S): Measures of psychological well-being and coping were administered. MAIN OUTCOME MEASURE(S): Biodemographic information, and psychometric measures of mood and coping. RESULT(S): There were no significant differences among the groups on any of the measures except the Family Inventory of Life Events (FILE), in which fertile men reported higher stress levels. FILE scores in all groups were moderate, indicating typical levels of family stress. CONCLUSION(S): Mood and coping in the three groups were similar. This study suggests that men's psychological adjustment to their own infertility and to unexplained infertility is generally healthy.

Irritability and sociability in women with symptomatic premenstrual change.

Sociability and irritability are commonly cited symptoms of premenstrual syndrome but there has been little investigation of these cycle related changes using clearly defined test instruments. We examined the two symptoms using symptom specific subscales from the Multiscore Depression Inventory (Berndt, 1983). Clear and consistent cycle related changes in irritability and sociability were seen in 20 women with prospectively validated symptomatic premenstrual change but not in a control group of 8 women without symptomatic premenstrual change. The study suggests that these variables can be measured using specific brief scales.

Factors determining fertility after conservative or radical surgical treatment for ectopic pregnancy.

OBJECTIVE: To examine factors determining choice of radical or conservative surgical procedure for tubal ectopic pregnancy and subsequent pregnancy rates. DESIGN: A retrospective study collating information from the operative notes and previous gynecologic history associated with the choice of procedure and pregnancy rates and outcome over 3 years after a primary tubal ectopic pregnancy. PATIENT(S): Thirty-four women who had undergone conservative (tube sparing) and 56 who had undergone radical (salpingectomy) surgical treatment for tubal ectopic pregnancy at least 3 years before the study. MAIN OUTCOME MEASURE(S): The main outcome measure was the occurrence of a pregnancy (live birth, miscarriage, or ectopic pregnancy) over 3 years after the ectopic pregnancy. RESULT(S): The type of surgery performed was not affected by a previous history of infertility, known pelvic inflammatory disease, the presence of tubal adhesions, or abnormalities on the contralateral tube. Intrauterine pregnancy was not more likely after conservative treatment of ectopic pregnancy but, equally important, the risk of a further ectopic pregnancy was not increased. The single factor that was clearly associated with future fertility problems was a past history of infertility. CONCLUSION(S): Better results may be obtained by careful selection of operative procedure based on history and findings at the time of surgery.

Exercise-associated amenorrhea, low bone density, and estrogen replacement therapy.

BACKGROUND: Women with exercise-associated amenorrhea have a higher frequency of osteoporosis than eumenorrheic runners and sedentary women. The use of hormone replacement therapy was suggested many years ago to increase bone density in exercising women with amenorrhea and low bone density. OBJECTIVE: To determine if hormone replacement therapy increased bone density in women with exercise-associated amenorrhea. METHODS: We performed a retrospective clinical study comparing the changes in bone density in 8 women runners who took hormone replacement therapy with 5 who refused medication but who were followed up as controls over 24 to 30 months. RESULTS: Vertebral and femoral neck bone density significantly increased by 8.0% +/- 1.2% (+/- SEM) and 4.1% +/- 0.3% (+/- SEM), respectively, in 8 women runners with amenorrhea taking 24 to 30 months of estrogen replacement therapy with progestational support. Control women not taking replacement therapy had nonsignificant decreases of less than 2.5% at each site. CONCLUSION: Hormone replacement therapy appears to increase bone density in amenorrheic runners.

Hormonal responses to graded-resistance, FES-assisted strength training in spinal cord-injured.

Functional electrical stimulation (FES) assisted resistance training has been effective in increasing muscular strength and endurance in spinal cord injured men and women in preparation for FES-assisted cycle programs and for FES-assisted standing and walking. Increases in blood pressure and a concomitant bradycardia suggestive of autonomic dysreflexia have been reported during FES-assisted resistance training. Self-induced autonomic dysreflexia in athletes who use wheelchairs suppressed the normal exercise induced serum testosterone increase. We, therefore, examined the changes in hematocrit and circulating levels of testosterone, sex hormone binding globulin (SHBG), cortisol, prolactin, norepinephrine and epinephrine during FES assisted resistance exercise in five high spinal cord injured men (SCI) and comparable maximal exercise in five able bodied controls (AB). Mean serum testosterone levels significantly increased with FES-assisted resistance training in SCI and maximal resistance exercise in AB with no significant change in hematocrit or SHBG. Prolactin, cortisol and epinephrine levels were unchanged while norepinephrine levels were significantly increased in SCI and AB. These findings suggest that there is no concern over inadequate physiological androgen response to an exercise stimulus in SCI. The data do not support the previous findings that elevated levels of norepinephrine in autonomic dysreflexia suppress testosterone response to exercise.

Oral alendronate induces progressive increases in bone mass of the spine, hip, and total body over 3 years in postmenopausal women with osteoporosis.

To determine the effects of long-term daily oral alendronate sodium (ALN) on bone mass in postmenopausal women with osteoporosis, 19 centers enrolled 516 postmenopausal women aged 45-80 years with spine bone mineral density (BMD) at least 2.5 SD below the mean for young premenopausal women in a 3-year, double-blind, placebo-controlled study. Subjects were randomly allocated to one of four treatment groups: placebo; alendronate, 5 or 10 mg/day for 3 years; or alendronate, 20 mg/day for 2 years followed by 5 mg/day for the 3rd year. All patients received 500 mg/day of supplemental calcium to ensure adequate calcium intake. BMD was measured by dual-energy X-ray absorptiometry at several skeletal sites. Nonsignificant mean decreases in BMD of the spine, femoral neck, and trochanter of 0.6, 0.7, and 0.4%, respectively, occurred in the placebo group at 3 years. Relative to placebo-treated patients, spine BMD increased by 5.4%, 7.4%, and 8.4% in the 5, 10, and 20/5 mg ALN groups, respectively. Increases at the femoral neck were 3.5%, 5.5%, and 4.3%, and those at the trochanter were 5.1%, 7.2%, and 7.2%, respectively. Thus, efficacy of 10 and 20/5 mg ALN was similar, whereas the 5 mg dose was less effective. BMD continued to increase over the entire 3-year study duration in the ALN-treated groups and, compared with the other dosage groups, 10 mg ALN produced the largest gains in BMD during the 3rd year. Changes in biochemical markers of bone turnover and mineral homeostasis confirmed the effect of ALN to decrease bone turnover to a new steady-state level. The safety and tolerability of ALN were comparable with those of placebo. In summary, 10 mg daily oral ALN given for 3 years significantly and progressively increases bone mass and is a generally well-tolerated treatment for osteoporosis in postmenopausal women.

Prolonged cancer death. A family affair.

The frequency with which families have to deal with cancer death is increasing as the population ages. The prevalence of some cancers in younger people is also increasing. In this article the authors focus on helping families deal with the anticipated cancer death of a family member. The article includes a definition of those groups of people who form families in the 1990s and examines dimensions along which families vary such as belief systems. We discuss the needs of families when a family member has a terminal cancer diagnosis and outline coping strategies that are seen in families and ways in which nurses and other health care professionals can facilitate adaptive coping.

Intermenstrual affect in women with symptomatic premenstrual change.

To determine whether women seeking treatment for symptomatic premenstrual change have ongoing psychological disturbance, we undertook a cross-sectional, comparative study across four groups of reproductive-age women. Subjects were 35 patients with symptomatic premenstrual change and no psychiatric history, 35 women without symptomatic premenstrual change, 35 patients with affective disorders, and 35 women from the community at large. All women except those in the community sample were tested in the intermenstrual phase (after menses but before the 12th cycle day). Psychological tests administered were Profile of Mood States, State-Trait Anxiety Inventory, Institute for Personality and Ability Testing (IPAT) Anxiety Scale, IPAT Depression Scale, General Health Questionnaire and the Family Inventory of Life Events (FILE). Demographic data and information concerning present and past stresses were also collected. Women with symptomatic premenstrual change were distinguishable from psychiatric patients on assessment of intermenstrual mood state. They were no different from women within the community at large or from non-symptomatic women. When symptomatic women reported on time periods, which include the premenstrual phase of the cycle, we found results at variance with those obtained in relation to current state mood. While not unlike the women from the community at large in longer term affective characteristics, they were consistently different from non-symptomatic women and sometimes indistinguishable from psychiatric patients. Women with symptomatic premenstrual change also reported higher levels of past external stresses than women taken from the community at large.

Fluid intake in women with premenstrual syndrome.

Fluid intake was measured at 3 phases of the menstrual cycle in twenty women with prospectively validated premenstrual syndrome and 8 women with prospectively validated absence of cyclic symptoms. There was no cycle related change in fluid intake in either group but fluid intake was significantly lower in women with PMS than in controls at all phases of the menstrual cycle. All subjects but one denied voluntary fluid restriction. The mechanism, therefore, appears subconscious and may be related to perceived increase in fluid retention.

"So mean and cranky, I could bite my mother": an ethnosemantic analysis of women's descriptions of premenstrual change.

Textual analysis was used to examine responses to an open ended question about women's experiences of premenstrual change. The question was the final item of the Premenstrual Assessment Form (PAF), a retrospective PMS questionnaire. Of the 336 women who answered the PAF, 261 provided a written narrative summary. We found a logical hierarchy of distinctions covering the presence or absence of changes, their timing, and attributive aspects, and a final cumulative distinction in which women provided information about the consequences of their premenstrual change. Although attribute aspects mirrored the PAF, distinctions in timing and in the cumulative effect of changes differed. The analysis suggests that questionnaires could be designed which more precisely reflect premenstrual change.

Evidence of autonomic dysreflexia during functional electrical stimulation in individuals with spinal cord injuries.

The purpose of the investigation was to examine the safety and efficacy of functional electrical stimulation (FES)-assisted hydraulic resistance training in improving cardiovascular fitness in persons with spinal cord injuries. The cardiopulmonary responses of 10 high spinal cord injured (SCI) and five able bodied (AB) subjects were assessed during three bouts of FES-assisted leg extension exercise. The protocol involved three 30-minute tests: (1) unloaded leg extension, (2) hydraulically-resisted leg extension (loaded), and (3) a reproduction of the unloaded and loaded protocols to measure cardiac output (Q). Pre-measurements were made of body mass, mean limb weight, maximal force output and maximal oxygen uptake (incremental arm ergometry). Oxygen uptake (VO2), minute ventilation (Ve), respiratory exchange ratio (RER), heart rate (HR), blood pressure (BP) were recorded before, during and after tests. There was a significant difference in VO2 max between SCI and AB subjects. Cardiac output significantly increased between the loaded and unloaded tests. The significant increases from rest to unloaded and loaded exercise pointed to the potential value of adding resistance to a leg extension training regime. Heart rate and BP of the participants with SCI consistently demonstrated a response suggestive of autonomic dysreflexia. Upon stimulation an immediate increase in (predominantly systolic) BP was observed, followed by a fall in HR. On cessation of stimulation HR exhibited a substantial rebound effect and BP returned to normal levels. This response was highly reproducible and suggests caution be exercised in the use of FES for people with SCI with lesion levels above the major splanchnic outflow (T6).

Electrical stimulation-assisted rowing exercise in spinal cord injured people. A pilot study.

Recently a FES (functional electrical stimulation)-assisted rowing machine was developed to enhance cardiovascular training in people with spinal cord injuries. The machine was assessed in terms of its efficacy as a training tool. Six patients who were quadriplegic (C6-T1) and 2 who were paraplegic (T3-6) completed a series of three tests in succession: (1) leg stimulation only (quadriceps and hamstring groups)--'Stim', (2) arm row only--'Row' and (3) simultaneous row and stimulation--'R & S'. Measurements recorded included oxygen uptake (VO2), minute ventilation (Ve), respiratory exchange ratio (RER), heart rate (HR) and blood pressure (BP). In addition, 6 out of the 8 subjects took part in a qualitative assessment comprising a guided interview exploring the subject's perception of the machine and test. Significant increases in VO2 were demonstrated between the three tests with R & S producing mean steady-state values of 16.34 nm (+/- 0.74) ml/kg/min (83% of maximum). These values represented a 12% increase over Row alone. Of interest was the qualitative assessment which revealed that subjects perceived R & S to be easier than Row despite the higher levels of VO2 observed. The results suggest that the rowing machine represents a potentially valuable hybrid training device that may significantly reduce risk factors for cardiovascular disease and improve the quality of life of people with SCI.

Hot flushes during breast feeding?

The initiation of breast-feeding was accompanied by an increase in skin conductance followed by increased skin temperature. The pattern was similar to that observed during a menopausal hot flush and differed from sympathetic arousal and simple heating.

Postmenopausal hyperandrogenism of ovarian origin. A clinicopathologic study of four cases.

Postmenopausal hyperandrogenism with overt clinical effects is rare and often related to ovarian stromal disorders. We present a clinicopathologic study of 4 cases. The patients (age range 41-75 years; mean 62 years) had evidence of hirsutism or frank virilization. Their serum testosterone was elevated with or without increases in their serum androstenedione and DHEA levels. There were two right-ovarian hilus cell tumors, one associated with left-ovarian stromal hyperplasia and the other with bilateral hyperthecosis and nodular hilus cell hyperplasia. The other tumor was a small corticomedullary stromal luteoma with bilateral hyperthecosis and nodular hilus cell hyperplasia. The fourth patient had bilateral hilus cell hyperplasia with mild cortical-stromal hyperplasia. All these patients had rapid normalization of androgen levels after surgery without recurrence after a 2- to 10-year follow-up.

Preventing Sexually Transmitted Diseases: Effecting behavioural change.

The discouraging results of early efforts to educate the public about sexually transmitted diseases indicated that the goals of STD preventive action must be longer term and must change attitudes and behaviour as well as educate. They must also avoid an ostrich mentality about the sexual involvement of young people. This article examines more recent approaches to teaching about sexuality in general and STD prevention in particular.
