The hypothalamic-pituitary-gonadal axis in mood disorders.

This article has demonstrated that stress and HPA axis activation affect the reproductive axis. Despite similarities in the HPA axis picture between women with major depression and those with hypothalamic amenorrhea and exercise or nutritional amenorrhea, no abnormalities in LH secretion have been documented in major depression. Lower estradiol in the follicular phase in depressed women and lower testosterone in depressed men however, have been observed [81, 92]. Although PMS would appear to be the best candidate for a mood disorder associated with abnormalities in reproductive hormones, no abnormalities in LH, estradiol or progesterone have been documented in PMS either [62]. Similarly, blockade of progesterone appears to be ineffective as a treatment for PMS [79]. Complete elimination of monthly cycling with leuprolide improves mood, however. No published studies have examined women with major depression to determine whether leuprolide will exacerbate or improve depressive symptoms. Some studies suggest beneficial effects of estrogen on mood in postmenopausal women, but no placebo controlled studies have explored estrogen augmentation in the treatment of major depression in either post- or premenopausal women, although estrogen is beneficial in women with perimenopause-related mood disorders [78].

Diabetes mellitus/male infertility.

Diabetes mellitus (DM), associated with very subtle disorders, affects, either directly or indirectly, various functions of the reproductive system. Adequate, regular, and timely therapy may prevent or delay these disorders. The T synthesis disorder is caused by molecular changes at the level of Leydig cells and may lead to other disorders in all target organs and tissues. The close correlation between Leydig and Sertoli cells function, i.e., between spermatogenesis and second sex glands function, results in certain anomalies in diabetic patients' spermiograms. Parallel lesions associated with DM, through CNS (hypothalamus-hypophysis), and endocrine profile are indirectly intensified or induced by these disorders, which reflect dysfunction of homeostatic balance in carbohydrate metabolism. Sexual dysfunction in all its forms (reduced erection, impotence, and other libido dissociations) is an accompanying phenomenon of the diabetic disease. However, manifestations of these disorders are related to the regulation of carbohydrate metabolism and to the duration of disease. The duration of disease is not necessarily correlated with sexual dysfunction. Even carbohydrate metabolism remains within normal range in addition to other lesions, diabetes leads gradually but progressively to premature aging of body cells.

Relationships of Fusarium toxins to tumours and other disorders in livestock.

Experimental laboratory animals treated with the trichothecene T-2 toxin, develop various acute and chronic disorders and also tumours of the digestive tract and of the brain. T-2 toxin is teratogenic and immunosuppressive. In livestock, ingestion of fodder contaminated with T-2 toxin and with certain other trichothecenes can cause various disorders, including a haemorrhagic syndrome, neurological and reproductive disturbances. Follow-up studies of survivors in the flocks or herds which suffered fatalities from acute mycotoxicoses could establish whether and which chronic disorders and tumours may develop among the survivors and among their progeny, as a result of exposure to mycotoxins, which caused the acute fatalities. Outbreaks of acute mycotoxicoses are usually preceded by exceptional weather.

Update on the management of polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder that affects 5% to 10% of women in reproductive age. It is the most simply defined as the association of hyperandrogenism (diagnosed clinically and/or biochemically) with chronic anovulation in the absence of specific ovarian, adrenal and pituitary gland diseases. Recent studies have revealed that PCOS is associated with hyperinsulinemia and insulin resistance. Both of them have been shown to play a substantial role in the increased risk of the cardiovascular events. The new data concerning the pathogenesis and management of PCOS have changed its treatment strategy. The management of PCOS is complex and includes lifestyle modification combined with dietary-induced weight loss, oral contraceptives, clomiphene citrate, gonadotropins, antiandrogens and insulin-sensitizing agents. Women with PCOS, diagnosed and managed properly, can benefit from the reduction or even reversal of the reproductive and metabolic morbidities and from the reduction of the risk factors for cardiovascular disorders. In this article, we describe all these treatment options. Although both standard and novel therapies are discussed, this review focuses on the progress made in the recent years.

Somatization disorder in family practice.

Although often difficult to recognize, somatization disorder--the presence of multiple physical symptoms but no apparent physical or psychiatric disease--is a common problem in primary care practices. Onset is usually before age 30. The disorder manifests as a myriad of symptoms, including gastrointestinal complaints, various types of pain, cardiopulmonary symptoms, pseudoneurologic complaints, sexual problems and complaints related to the female reproductive system. Vigilance is necessary, because somatization disorder may mimic numerous physical and psychiatric ailments.

Integrating occupational health and safety into the health education classroom.

Given the startling number of job-related illnesses and injuries which occur every year, occupational health and safety, a hitherto neglected topic, deserves significant attention in the school health education curriculum. Youngsters need to be exposed to this field before they become indifferent or callous toward diseases and accidents in the workplace and while the opportunity still exists to weight health and safety considerations in selecting a career. In addition, when students take up regular employment, they cannot rely on industry, government, or organized labor to protect them fully from occupational illnesses and accidents; they must possess the skills and attitudes necessary to safeguard themselves. Occupational health and safety education in the schools can focus on general awareness, skill development, and job-specific information. The field can be easily and appropriately integrated with a number of current health education topics. Examples of integration are provided for eleven typical areas of a school health education curriculum.

Sleep, rhythms and women's mood. Part II. Menopause.

This review summarizes studies of sleep and other biological rhythms in menopausal women with major depression compared with healthy control subjects. Where feasible, we focused on studies in women who met DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) criteria for a major depressive episode (MDE) compared with matched normal control subjects and the Staging System for Reproductive Aging in Women (STRAW) criteria. The aim was to review supporting evidence for the hypothesis that a disruption of the normal temporal relationship between sleep and other biological rhythms, such as melatonin, cortisol, thyroid stimulating hormone (TSH) or prolactin, occur during the menopausal transition. As a result, depressive disorders occur in predisposed women. Treatment strategies, designed to correct these altered phase (timing) or amplitude abnormalities, thereby improve mood. Although there may be some common features to menopausal depression compared with other depressive disorders related to the reproductive cycle (e.g. premenstrual dysphoric disorder or postpartum major depression), such as increased morning melatonin secretion, a specific profile of sleep and biological rhythms may distinguish healthy from depressed women during menopause. Further work is needed to characterize more fully the particular abnormalities associated with well-defined menopausal depression in order to develop treatment strategies targeted more specifically to pathogenesis.

Animal models of cognitive dysfunction.

The increased life expectancy in industrialised countries in the last half century has also brought to a greater incidence of neurological disorders, including neurodegenerative diseases and developing in a rather long time. In this respect, Alzheimer's disease (AD), for the large incidence, and the dramatic loss of autonomy caused by its cognitive and behavioural symptoms represents one of the main challenges of modern medicine. Although AD is a typical human disease and probably includes several nosographic entities, the use of animal models may contribute to understand specific aspects of pathophysiology of the disease. The most widely used animal models are rodents and non-human primates. In this review different animal models characterised by impaired cognitive functions are analysed. None of the models available mimics exactly cognitive, behavioural, biochemical and histopathological abnormalities observed in neurological disorders characterised by cognitive impairment. However, partial reproduction of neuropathology and/or cognitive deficits of Alzheimer's disease (AD), vascular dementia and dementia occurring in Huntington's and Parkinson's diseases, or in other neurodegenerative disorders may represent a basis for understanding pathophysiological traits of these diseases and for contributing to their treatments.

Spasmodic torticollis: clinical and biologic features and their implications for focal dystonia.

A previous investigation of IST in Rochester, Minnesota, from 1960 through 1979 yielded an incidence of 1.1/100,000 person-years. The rate in women was almost three times higher than that in men. Thyroid disorders, other endocrine disorders, right-hand preference, symptomatic ovarian cysts, other disorders of the female genito-reproductive system, emotional depression, cerebral aneurysm, and family history of diabetes mellitus were common. In 347 cases of IST personally evaluated (151 seen between 1969-1971, a sample of 49 seen in 1978, and 147 other cases evaluated in 1985) the female-to-male ratio was 1.6:1. The mean age at onset was 43.5 years for women and 42 years for men, and the distributions of age at onset were virtually identical for the two sexes. Thyroid disorder was prevalent in all three referral patients samples. The increased frequency of thyroid disorder was due to a high overall frequency in female patients, 28.4% (95% confidence interval, 22.3-34.4%). Thyroid disorders were 4.5 times more frequent in women with IST than in men with IST. In the control population of 61 patients with peripheral sensory neuropathy, in which sex distribution and mean age at onset of symptoms were comparable to those in IST patients, the incidence of thyroid disorder overall was only 8.2% (in women, 6.6%). Only 12 of the 347 referral IST patients were non-right-handers. Five of these 12 were female patients (2.3% of the 215 women; 95% confidence interval, 0.3-4.3%), significantly below the anticipated frequency (10%) or the observed frequency (10% and 15.16%) in two attempted control populations. Light eyes seem to be unusually common in IST patients, as are personal and family histories of essential tremor. These results may reflect shared biologic risk factors which relate age, gender or estradiol/testosterone function, cerebral anatomic and chemical lateralization, endocrinopathy including elevated thyrotropin levels, immune status, emotional depression, common cells of origin in the neural crest, race, and familial occurrence to IST and other focal dystonias and essential tremor.

Exercise-induced endocrine pathologies.

There has been a substantial increase in women practicing sports over the past 30 yr. While exercise provides many health benefits, there appears to be a unique set of risks associated with intense exercise for the female athlete. The female athlete triad encompasses these risks, including amenorrhea, osteoporosis and eating disorders. The incidence of menstrual irregularities including primary and secondary amenorrhea and shortened luteal phases is much higher among women partaking in athletics, specifically in sports requiring low body weight for performance and aesthetics. The hormone pattern seen in these amenorrheic athletes includes a decrease in GnRH pulses from the hypothalamus, which results in decreased pulsatile secretion of LH and FSH and shuts down stimulation of the ovary. The recently discovered hormone leptin may also play a large role as a significant mediator of reproductive function. The prevalence of eating disorders is high among female athletes who practice sports which emphasize leanness. Consequently, the cause of menstrual irregularities is not due to the exercise alone, but to chronic inadequate or restrictive caloric intake that does not compensate for the energy expenditure. The most dangerous risk associated with amenorrhea for the female athlete is the impact on the skeleton. Complications associated with amenorrhea include compromised bone density, failure to attain peak bone mass in adolescence and increased risk of stress fractures. The diagnosis of exercise-associated menstrual dysfunctions is one of exclusion. The most effective treatment is to decrease the intensity of the exercise and increase the nutritional intake. Hormone replacement has also been under investigation as a possible treatment.

Nutrition and reproduction in women.

Malnutrition is a major problem in developing countries, and obesity and eating disorders are increasingly common in developing as well as developed countries. The reproductive axis is closely linked to nutritional status, especially undernutrition in the female, and inhibitory pathways involving detectors in the hind brain suppress ovulation in subjects with weight loss. Recovery may occur after minimal reacquisition of weight because energy balance is more important than body fat mass. Anorexia nervosa and bulimia nervosa affect up to 5% of women of reproductive age causing amenorrhoea, infertility and, in those who do conceive, an increased likelihood of miscarriage. Obesity can affect reproduction through fat cell metabolism, steroids and secretion of proteins such as leptin and adiponectin and through changes induced at the level of important homeostatic factors such as pancreatic secretion of insulin, androgen synthesis by the ovary and sex hormone-binding globulin (SHBG) production by the liver. WHO estimates that 9 to 25% of women in developed countries are severely obese, and obese mothers are much more likely to have obese children, especially if they have gestational diabetes. Obesity-associated anovulation may lead to infertility and to a higher risk of miscarriage. Management of anovulation with obesity involves diet and exercise as well as standard approaches to ovulation induction. Many obese women conceive without assistance, but pregnancies in obese women have increased rates of pregnancy-associated hypertension, gestational diabetes, large babies, Cesarean section and perinatal mortality and morbidity. Among contraceptors, the fear of weight gain affects uptake and continuation of hormonal contraceptives, although existing trials indicate that any such effects are small. For all methods of hormonal contraception, weight above 70 kg is associated with increased failure rates.

Acute urinary retention after use of assisted reproductive technology. A report of 2 cases.

BACKGROUND: Urinary retention in women is an unusual occurrence. Various conditions can cause it, including surgery, childbirth, pelvic masses, procidentia, vulva hematoma, incarceration of a gravid uterus, urologic disease, neurogenic disease and psychiatric disorders. CASES: Two infertile women underwent assisted reproductive technology (ART) and luteal-phase support during which acute urinary retention occurred. The patients were evaluated by means of physical examination, urodynamic study and determination of serum progesterone levels. Bladder distention was found during luteal-phase support. Urodynamic studies revealed detrusor areflexia. Serial serum progesterone levels were > 100 ng/mL. CONCLUSION: Cases of acute urine retention during luteal-phase support are rarely reported. Urine retention should be considered in the differential diagnosis when abdominal pain occurs after patients undergo ART. Transient elevation of the progesterone level may be the cause of the acute urine retention.

Zearalenone applied per os provides adverse effects in structure of chosen parts of bitch reproductive system.

Both earlier investigations and complete formulas of pet food for dogs show that professionally prepared pet food is based in 30% on the material of the plant origin. Our own investigations prove that animal feeding stuffs of the plant origin are very often vectors of many undesirable substances (including micotoxins) that are unfavourable for carnivores. Zearalenone is a micotoxin, which frequently occurs among them. It was revealed in pet food in quantities from 5.0-299.5 microg/kg. It is a very dangerous xenobiotic because of its quick and easy absorption in the organism after per os application in monogastric animals. It is also a sterid and despite its plant origin it binds estrogen receptors in the reproductive tract and causes its hypo- and dysfunction. It is clearly visible in young, growing organisms and those during the menopause. In bitches, dysfunctions of the reproduction system, such as: endometritis-pyometra syndrome, prolonged oestrus, ovarian cysts and others are often found. It is supposed that specific for this species hormonal regulation of the reproduction processes based on the long progesterone and prolactin cycles, and on high sensibility to estrogens plays an important role in the etiopathogenesis of these dysfunctions. The application of hormones in bitches in therapeutic and biotechnical (contraception) purposes are the other factors, which should be taken into account in this aspect. There are some suggestions that therapeutic management, unfortunately connected with mistakes in the medical art, is often a cause of pathological condition in a reproductive organ in bitches. However, another reason of these disorders may be that bitches take zearalenone with the commercial pet food. The long-lasting intake of the feed with a low dose of this micotoxin may be the factor, which complicates hormonal regulation of the reproduction processes and is the cause of many disorders. Our own pilotage investigations showed that application of zearalenone at a dose of 200 microg/kg b.w. for 7 days leads to apoptotic-like changes in granule cells in the bitch reproductive system, atresia of follicular cells and oedema and hyperplasia of the oviductal and uterine cells. They could also indicate a follicular phase of the oestrus cycle in bitch. However, it did not take place.

[Pulmonary lymphangiomyomatosis with tuberous sclerosis and endolymphatic stromal myosis of the uterus].

Pulmonary lymphangiomyomatosis is a rare disorder that affects only women of reproductive age. The lung shows numerous cystic changes and striking proliferation of smooth muscle around the airways, blood vessels, and lymphatic channels. We encountered a patient with pulmonary lymphangiomyomatosis who had repeated pneumothorax and bloody sputum over 10 years. The patient also had other lesions, including intracranial calcification, renal angiomyolipoma and endolymphatic stromal myosis of the uterus. The first two findings are known as tuberous sclerosis, and lymphangiomyomatosis is considered to be a form fruste of tuberous sclerosis. However, we know of no previous reports of uterine lesions in this disease. Lymphangiomyomatosis may be a systemic disorder of smooth muscle.

Sex differences in depression and anxiety disorders: potential biological determinants.

The phenomenon of higher rates of affective disorders in women illustrates many of the difficulties as well as promises of translating preclinical models to human disorders. Abnormalities in the regulation of the hypothalamic-pituitary adrenal axis and the sympathoadrenomedullary system have been identified in depression and anxiety disorders, and these disorders are clearly precipitated and exacerbated by stress. Despite the striking sex difference in the prevalence of depression and anxiety disorders, attempts to identify corresponding sex differences in stress response reactivity in animal models have met with limited success. Processes which may contribute to increased rates of affective disorders in women are greater fluxes in reproductive hormones across the life span, and increased sensitivity to catecholamine augmentation of emotional memory consolidation.
