Small-intestinal cryptosporidiosis in a chicken.

Severe small-intestinal cryptosporidiosis was diagnosed in a chicken that had diarrhea, was weak, and had failed to thrive. Intestine segments also were parasitized by Eimeria sp. and bacteria.

Leukocyte changes associated with acute inflammation in chickens.

Leukocyte changes in chickens with turpentine-induced inflammation were investigated sequentially at 0, 6, 12, and 24 hours and at 2, 3, 4, 7, and 14 days. During acute inflammation, significant leukocytosis and heterophilia developed by 6 hours and persisted through 7 days. The peak mean heterophil and leukocyte counts occurred at 12 hours and 3 days, respectively.

Rapid cytologic diagnosis of respiratory cryptosporidiosis in chickens.

A method is presented for the rapid cytologic detection of cryptosporidial oocysts in Diff-Quik and modified Kinyoun acid-fast-stained tracheal imprints. On Diff-Quik-stained preparations, cryptosporidial oocysts were observed attached to the apical ends of respiratory epithelial cells or scattered throughout the imprint. These oocysts were round to oval, measured approximately 6 to 7 micron in diameter, and appeared faintly blue with fine pink granules.

Histologic incidence and distribution of Cryptosporidium sp. infection in chickens: 68 cases in 1986.

In 1986, a retrospective examination of histologic data determined that 68 histology accessions at the Georgia Poultry Laboratories had a diagnosis of cryptosporidiosis. These cases represented 6.4% of the 1065 histologic examinations of chickens performed at the facility.

Deinstitutionalization: a new scenario.

Deinstitutionalization appears to be an issue that is still pretty much up in the air. The public, courts, and state hospital administrators agree that large state, warehouse-like facilities are inadequate. The appropriate mental health delivery system for each state and the communities within each state need careful planning and implementation to be successful.

Diarrhea associated with intestinal Cryptosporidiosis in turkeys.

Turkey poults were suffering from diarrhea on a farm in which several previous grow-outs of turkeys had experienced a clinically identical problem. Upon necropsy, significant gross lesions were restricted to the gastrointestinal tract. Segments of small intestine were pale and distended with cloudy mucoid material and a few gas bubbles.

Prolonged selective urokinase infusion in totally occluded coronary arteries and bypass grafts: two case reports.

Reports are presented demonstrating a technique for dissolving thrombus in coronary arteries and bypass grafts by using prolonged selective infusion of urokinase via an infusion wire. This allows one to pass a steerable guide wire through the culprit stenosis and perform angioplasty on a distal lesion which could not be previously seen.

Assessment of the Albuscreen microalbuminuria kit in diabetic outpatients.

Diabetic patients who have albumin excretion rates of greater than 30 micrograms/min (30 mg/L at normal urine volumes) are at increased risk of the development of diabetic nephropathy. The Albuscreen microalbuminuria kit detects albuminuria at concentrations of 30 mg/L and above by an agglutination-inhibition reaction. One hundred and ninety-five random urine samples from diabetic outpatients were assessed by Albuscreen and Albustix testing for albuminuria and the results were correlated with those of a sensitive radioimmunoassay technique.

Anomalous thyrotropin values.

We studied problems associated with use of an "ultrasensitive" thyrotropin (TSH, thyroid-stimulating hormone) assay for diagnosis of hyperthyroidism. Of 955 TSH assays performed in our laboratory during four months, 135 gave TSH values less than 0.1 milli-int.

Hypomyelination in Weimaraner dogs.

Dogs from two separate litters of Weimaraners developed tremors by 3 weeks of age. Light and electron microscopic findings in one dog from each of the litters were compared to those of two age-matched controls. Many axons in the brain and spinal cord were either thinly myelinated or nonmyelinated in the affected dogs relative to the controls, while the peripheral nervous system was normally myelinated.

Adolescents' knowledge of nuclear issues and the effects of nuclear war.

Three hundred fifty-seven college students were surveyed to assess later adolescents' awareness of the status of nuclear arms development and possible effects of a nuclear war on people and the environment. Chi-square analyses were performed to determine whether the frequency of correct responses differed with regard to participants' sex, political orientation, and position toward the United States' possession of nuclear weapons. Results suggest that later adolescents are extremely uninformed regarding the current status of nuclear issues and the consequences of a nuclear war.

Wheelchair use by ambulatory nursing home residents.

In a survey of wheelchair use in two nursing homes, the authors found a substantial number of cognitively intact nursing home residents who walked, but who also used a wheelchair. Using chart review and interviews with the residents, it was found that multiple physical factors, including pain, strength, endurance, vision and balance, and multiple social and environmental factors, including the fear of falling, were related to the resident's decision to use a wheelchair as an alternative means of mobility. A physical examination focused on aspects of mobility was completed on each resident and was intended to characterize the physical limitations in groups studied.

Studies on orthoreoviruses isolated from young turkeys. III. Pathogenic effects in chicken embryos, chicks, poults, and suckling mice.

The pathogenicity of four clone-purified reoviruses (81-51, 81-68, 81-311, and 82-88) was studied in experimentally infected specific-pathogen-free (SPF) chicken embryos and chicks. SPF and specific-antigen-and-antibody-negative (SAAN) turkey poults, and suckling mice. In SPF embryos, all four viruses caused death or lesions characteristic for avian reoviruses.

Medicare's prospective payment system for hospitals: the impact on nursing home quality.

How are changes in Medicare affecting the quality of long term care? Finding an answer to this question is made difficult by the many variables that must be considered and the lack of concrete data on the subject. The variables include the care requirements of Medicare patients being discharged from hospitals to nursing homes, the availability and accessibility of skilled-care beds, the trends in utilization of skilled-care beds, and the capability of nursing homes to provide the care required by these patients. Anecdotal data suggest that Medicare patients are being discharged from hospitals earlier, sicker, and with more complex skilled nursing requirements than before the implementation of prospective payment, that there has been limited collaboration among hospitals and nursing homes during this period of transition in the Medicare system, and that nursing home administrators and staffs are increasingly concerned about the actual cost of providing care to a sicker group of patients and about the qualifications of staff to meet more complex care needs.
