The clinical syndrome of a new disease of pigs in four herds in the Humberside area is described. The first signs of the disease were anorexia, lethargy and pyrexia with up to 60 per cent of the dry sows affected. These signs were followed by an increased incidence of abortions which occurred in up to 3.3 per cent of sows, premature farrowings in up to 20.6 per cent of sows and stillbirths and late mummification which affected up to 26.0 and 18.8 per cent of fetuses, respectively. Mortality in neonatal and pre-weaning pigs reached up to 88 per cent and respiratory disease of high morbidity and low mortality occurred in fattening pigs. There were infertility problems in sows, with an increase in returns to service and a failure to show oestrus after weaning or aborting. The signs of the disease in boars were anorexia and malaise. Cyanosis of the extremities affected up to 2 per cent of the animals. The outbreak lasted 11 weeks in all the herds.

The purpose of this study was to experimentally reproduce swine infertility and respiratory syndrome (SIRS). Six multiparous sows were intranasally inoculated at 93 days of gestation with lung homogenates from clinically affected pigs, and 3 additional sows were similarly inoculated with a virus isolated in cell culture from the lung homogenate (SIRS virus, isolate ATCC VR-2332). Inoculated sows developed transient anorexia, farrowed up to 7 days prematurely, and delivered a mean of 5.8 live pigs and 6.0 dead fetuses/litter. Clinical signs of disease were not observed in 3 sham-inoculated control sows that delivered a mean of 12.7 live pigs and 0.3 stillborn fetuses/litter. The SIRS virus was isolated from 50 of 76 live-born and stillborn fetuses from the 9 infected litters. Virus was not isolated from 26 autolyzed fetuses or 15 control pigs. Six of 9 inoculated sows developed neutralizing antibodies to SIRS virus. The reproductive effects found in these experiments were identical to those found in field cases. On the basis of our findings, virus isolate ATCC VR-2332 causes the reproductive failure associated with SIRS.

Mammary adenocarcinoma was diagnosed in a 3-year-old Landrace sow with prolonged infertility, anorexia and progressive emaciation after parturition. Gross examination confirmed a large tumour in the left anterior mammary gland with metastatic nodules on the pleura and in the parenchyma of lung. Microscopically, the tumour consisted mainly of solid adenomatous proliferations with numerous mitotic figures. Irregular glandular structures, solid nests of polygonal tumour cells without polarity and nests consisting of glandular, cribriform and solid portions were evident in dense fibrous stroma. Immunostaining revealed keratin in the tumour cells.

Animal experiments conducted in the late 1960s and early 1970s in various institutes of China showed that the effective antifertility agent in crude cottonseed oil was gossypol. Gossypol is a yellow substance which occurs in various parts of the cotton plant; its chemical structure is naphthol phenol. At the Capital Hospital gossypol was tested on 172 volunteers selected from hospital employees and workers from a nearby factory. All of the volunteers were under age 50, married and healthy with at least 1 child. Examinations required before treatment were general physical examination, a blood and urine analysis, an electrocardiogram, serum potassium concentration and serum analysis. 2 stages of gossypol treatment were required in the clinical study: the initial stage, the loading period, is of about 60 days. A daily dose of 20 mg gossypol was given successively for 60 days causing the sperms to become immotile, reduced in number or totally absent. A sperm count below 4 million/ml semen was considered to indicate infertility. The dosage in the 2nd stage, the maintenance period, was reduced to 1/3 of the original dose to maintain infertility. The volunteers were followed up every 2-3 months. Fatigue, decrease of libido and impaired appetite were the 3 main complaints. Serum glutamic-pyruvic transaminase (SGPT) activities showed that the transient symptoms of fatigue and loss of appetite were not related to disturbance of liver function. The mechanism of hypokalemia induced by gossypol is probably of renal origin. Infertility induced by gossypol in contraceptive doses over a relatively short period of administration was reversed about 3 months after stopping treatment. Gossypol used as a male antifertility agent has been found to be very effective and relatively safe.

A 16-month-old Charolais bull was examined because of acute onset of scrotal and hind limb edema, fever, tachycardia, tachypnea, anorexia, and lethargy. Scrotal circumference on initial examination was 48 cm. Clinicopathologic abnormalities included microcytic, normochromic anemia and numerous Eperythrozoon organisms in blood smears. Results of immunohistochemical staining of a skin biopsy specimen suggested that the edema was the result of an Arthus-type reaction. Semen quality deteriorated rapidly, and the bull was aspermic within 7 days. The bull was treated with oxytetracycline, and the anemia and edema gradually subsided. Eperythrozoon organisms were not detected in blood smears after 3 days. Six months after initial examination, results of physical examination and semen evaluation were normal. We hypothesize that scrotal edema caused failure of testicular thermoregulation, resulting in transient production of abnormal sperm and infertility.

Sleeping sickness (SS; African trypanosomiasis) is an anthropozoonosis transmitted by the tsetse fly. Infection with Trypanosoma brucei in humans is associated with adynamia, lethargy, anorexia, and more specifically amenorrhea/infertility in women and loss of libido/impotence in men. Recent evidence suggests that experimental infection in animals with Trypanosoma brucei species causes polyglandular endocrine failure by local inflammation of the pituitary, thyroid, adrenal, and gonadal glands. In a cross-sectional study we investigated the prevalence and significance of neuroendocrine abnormalities in 137 Ugandan patients with SS. In the untreated stage of the disease, there was a high prevalence of adrenal insufficiency (27%), hypothyroidism (50%) and hypogonadism (85%). Pituitary function tests suggested an unusual combined central (hypothalamic/pituitary) and peripheral defect in hormone secretion. Specific therapy resulted in a rapid recovery of adrenal/thyroid function, whereas hypogonadism persisted for years in a substantial portion of patients. We did not detect pituitary, thyroid, adrenal, and gonadal autoantibodies in patients with endocrine dysfunction, ruling out an autoimmune origin of the endocrine abnormalities. However, the presence of hypopituitarism correlated with high cytokine concentrations (TNF-alpha, IL-6) which--together with direct parasitic infiltration of the endocrine glands--are involved in the pathogenesis of SS-associated endocrine dysfunction.

EATING DISORDERS: The development of somatic complications observed in patients with eating disorders depends both on the duration of the clinical course and on the gravity of the symptoms and psychological factors. It would thus appear advisable to obtain a complete endocrine (gonadotropic, thyroid, hypothalamo-hypophyseal-adrenal) work-up which could be repeated every year after the patient has controlled the behavior disorder. Two aspects of these complications predominate: osteoporosis and infertility. OSTEOPOROSIS: A common finding after anorexia nevrosa, osteoporosis can lead to multiple, sometimes spontaneous, fractures. Bone mass can be assessed with biphotonic absorptiometry. The indication for estroprogestogen prophylaxis is debatable, depending on the patient's psychological profile, but also because efficacy has not always been demonstrated. Third-generation biphosphonates appear to offer promising results. INFERTILITY: Among a population of women consulting for infertility, a non-negligible percentage have infraclinical manifestations of anorexia nevrosa. The question of prescribing estroprogestogens, which would allow normal cycles and a certain vaginal trophicity, is often raised. We advocate a dose coordination between endocrinologists, infertility specialists and psychiatrists in order to better define the precise modalities of a given treatment aimed at regulating hypothalamo-pituitary function or favoring procreation.

We describe endometriosis in an aged rhesus macaque. There was a large mass and a related paraovarian cyst, typical of the disease. Endometriosis is a common finding in nonhuman primate. In this report, we also review the pathophysiology of the disease and summarize the historical and more recent relevant literature. Given the frequency of endometriosis in the rhesus monkey and the long-life spans (15-30 years) of nonhuman primates in captivity, endometriosis should be suspected in animals displaying the earliest signs of the disease: anorexia, dysmenorrhea, menorrhagia, irregular menstrual cycles, or infertility. Despite recent advances in the diagnosis and therapeutic strategies for endometriosis in women, the disease remains a significant cause of morbidity and ultimately, a cause of mortality, in the older nonhuman primate.

The present study dealt with the interaction between body composition estimated by means of dual energy x-ray absorptiometry, sex-specific fat distribution and sex hormone levels (LH, FSH, estradiol, prolactin, DHEA-S, androstendione, testosterone and SHBG) as well as LH and FSH fluctuations in infertile young women ageing between 18 and 30 years (x = 23.4 yr). Twenty patients suffered from polycystic ovaries (PCO), 15 women suffering from a mild anorexia nervosa were amenorrhoeic for more than one year. Marked associations between estradiol, testosterone, SHBG as well as the FSH output and body fat, bone mass and fat distribution were documented. PCO patients exhibited a high weight status and a typical android fat distribution which signals infertility comparable to postmenopausal women. In contrast, although anorexia patients had pathological decreased estrogen levels and were infertile at the time of investigation, their fat distribution was be classified as 'ypergynoid' and signals potential reproductive capability after a sufficient weight gain.

There are several possible causes for amenorrhea. Two of the most common are mental anorexia and psychological shock. To perform laparoscopy in such cases would be of limited effect. Laparoscopy is useful in patients with ovarian hyperandrogenia. The cases for which laparoscopy is indicated are listed and explained. Laparoscopy helps explain luteal insufficiency which provoke infertility. However, one should not try to multiply the indications of this procedures.
