Manually assisted ejaculation in a stallion with erectile dysfunction subsequent to paraphimosis.

A Thoroughbred stallion with erectile dysfunction following paraphimosis was managed to allow consistent ejaculation. Ejaculation was elicited in this stallion by applying manual stimulation to the base of the penis. This technique allowed consistent ejaculation, and the stallion was able to return to natural service. Historically, stallions with this degree of penile dysfunction have been considered incapable of ejaculation and unable to continue as breeding animals.

Ejaculatory failure associated with aortic-iliac thrombosis in two stallions.

Two mature breeding stallions were evaluated because of specific ejaculatory dysfunction, and each was found to have aortic-iliac thrombosis occluding 60 to 70% of the aortic lumen. In each case, the stallion had strong libido, normal mounting, and vigorous initial thrusting. With continued exertion, thrusting became weak and dismount was awkward. Treatment aimed at maximizing sexual arousal before mounting and reducing hind limb pain and exertion during breeding allowed these stallions to continue breeding. A program of gradually increasing daily exercise also was associated with improved breeding performance during subsequent breeding seasons. In cases of specific ejaculatory dysfunction, aortic-iliac disease should be included among the differential diagnoses.

Semen collection techniques.

Semen collection techniques in the stallion have evolved considerably over the last 70 to 80 years and are used today primarily for artificial insemination. Semen can be collected from stallions that are otherwise unable to breed, allowing continued use of valuable animals. There are many options for collection of semen from stallions that present with ejaculatory dysfunction (see the article by McDonnell elsewhere in this issue.) Although there are many advantages to the use of artificial breeding, the collector must understand each step of the collection procedure as well as stallion preferences and proper use of an artificial vagina and mount source so that a representative semen sample is collected.

Violence toward health care workers: an emerging occupational hazard.

1. Violence toward health care workers has only recently been addressed as an occupational health hazard and research in this area is in its infancy. 2. Violent incidents are severely underreported and when studied are usually limited to formal incident reports. 3. Identified environmental risk factors for assaults include staffing patterns, time of day, and containment activities. 4. Health care institutions need to be educated that they have much to gain from efforts to identify and reduce the current epidemic of violence in these settings.

Pathological changes of the mare endometrium and genotypes for transferrin and ELA.

Histological features of the endometrium, as assessed in biopsy samples, were related to Standardbred mare genotypes for transferrin, esterase (as a control) and equine leucocyte antigens (ELA). Pathological changes were found more frequently in each successively older age group of mares. Among mares aged 6-19 years, there were significant pathologic changes on first examination following an infertile breeding season for 46 of 90 (51%) of transferrin homozygotes and 50 of 146 (34%) of transferrin heterozygotes. The difference between the two groups was significant for the total data (chi 1(2) = 6.56, P = 0.010) and when the data were stratified for mare age at biopsy (chi 1(2) = 7.33, P = 0.0068). The effect of transferrin was similar in both trotters and pacers, especially for frequent genotypes commonly found in horses of both gaits. There was no effect of esterase and, in a smaller set of ELA-typed mares, no significant effect of ELA genotype on uterine biopsy category. Transferrin has a well-established microbiostatic and biocidal effect. Conceivably, heterozygotes for some combinations of transferrin variants could have a slower natural rate of endometrial deterioration than homozygotes.

Evaluation of measures taken by ultrasonography and caliper to estimate testicular volume and predict daily sperm output in the stallion.

The semen of 26 stallions, 2-20 years of age, was collected once a day for 7 consecutive days to determine daily sperm output (DSO). After the last collection, 17 stallions were castrated. Testicular volume was estimated using two methods. Length, width, height, of each testis were measured by caliper. Length, width, height, cross-sectional area and circumference at the widest point of the testis were measured by ultrasonography. Both caliper and ultrasound measurements were first made in the live animal, and again in vitro. There were no differences in these measurements because of method or condition of the animal, i.e., whether the measures were taken in the live animal or after castration. The volume of an ellipsoid (4/3 pi abc, a = height/2, b = width/2, c = length/2) is introduced as a method of accurately estimating testicular volume (r = 0.99) as well as predicting DSO (r = 0.92) in the stallion. The authors of this report suggest that this estimation can be performed by substituting values derived by ultrasonography or calipers.

Eating disorders. Highlights of nursing assessment and therapeutics.

Nurses providing care for individuals with eating disorders should identify and test the effectiveness of various milieu factors and nursing therapeutics employed in the treatment of these often-debilitating disorders. Nurses offer presence, role modeling, surveillance, and emotional and physiologic support while guiding reluctant patients to explore and experiment with new behaviors. Nurses provide flexibility, empathy, and rational limit setting in response to the unique and shifting needs of each patient. This interpersonal dynamic is often extremely different from that experienced in the patient's family of origin and, thus, contributes to the essential "interpersonal conditions" that are necessary for the patient to engage meaningfully in treatment. The prevalence of eating disorders suggests that nurses are likely to encounter people with eating disorders in many settings. Nurses should be skilled at spotting disordered eating among an array of clinical presentations (e.g., amenorrhea, disturbed family relationships, athletic injuries) because people engaged in disordered eating are hesitant to volunteer such information. In addition to the shame associated with disordered eating is the stigma associated with psychiatric treatment. Seeking help from a nurse may be perceived as less stigmatizing than seeking care from a psychiatrist. Thus, nurses may serve as important points of entry for the hesitant patient. The initial contact is so essential in setting the stage for the continuation and denouement of therapy. Finally, nurses and patients with disordered eating share at least one commonality. Both groups are predominantly women. The prevailing culture has been implicated repeatedly as a major factor in contributing to the prevalence of disordered eating. Nurses experience the influences of paternalism in their professional practice and confront daily the pressures of socially constructed feminine ideals. These gender-sensitive ways of knowing, which nurses bring to the treatment relationship, should be further analyzed as substantive dimensions with treatment and preventive potential.

Endometrial concentrations of ampicillin in mares after intrauterine infusion of the drug.

Serum concentration of ampicillin, a semisynthetic penicillin, was measured in mares at various time intervals up to 24 hours after intrauterine infusion of 3 g of ampicillin. Blood samples were drawn immediately before infusion and at 1-, 4-, 10- and 24-hour intervals after infusion. At postinfusion hour 24, two endometrial biopsy specimens were obtained to measure endometrial concentrations of ampicillin. Blood was drawn twice as part of the 24-hour postinfusion sample collection, once before removal of the biopsy specimens and again 5 minutes after removal of the biopsy specimens. After drug infusion, more diestrous mares had detectable serum ampicillin concentration than did estrous mares for all samples, except the 24-hour prebiopsy sample. None of the 24-hour prebiopsy serum samples had detectable ampicillin concentration, but ampicillin was detected in the serum of 4 of 5 diestrous mares after endometrial biopsy. Endometrial concentrations of ampicillin were detectable at postinfusion hour 24 in estrous and diestrous mares, but were not different. All 24-hour biopsy specimens had ampicillin concentrations greater than the ampicillin minimal inhibitory concentration.

Bilateral seminal vesiculitis and ampullitis in a stallion.

A Thoroughbred stallion suspected of having venereal disease was found to have an infection of the accessory sex glands. Purulent debris, blood, and Pseudomonas aeruginosa were recovered from all ejaculates. Treatment with gentamicin sulfate, tobramycin, and amikacin sulfate was unsuccessful in eliminating the infection. The stallion's seminal plasma, collected during treatment with gentamicin sulfate, did not contain any appreciable antibacterial activity. Apparently, negligible amounts of gentamicin diffused across the mucosal cell borders of the accessory sex glands into the seminal plasma. Bilateral seminal vesiculitis and ampullitis were evident on examination of the reproductive tract when the stallion was euthanatized.
