Social support and cancer: adult patients' desire for support from family, friends, and health professionals.

Examined cancer patients' desire for social support from family, friends, and health professionals upon whom they most depended for support. Before a single interaction with each of these sources, nonhospitalized adult cancer patients (N = 64) completed a questionnaire indicating their desire for support from the source on 11 functional components. Results indicated that emotional and instrumental functions of support were distinct and required separate examination. Distinctiveness of primary sources was manifest by patients' overall preference for tangible aid from family, modeling from friends who had cancer, and open communication and clarification from health professionals. Family and friends were equally preferred sources for dealing with affective reactions to the stressfulness of cancer. All three sources were similarly desired for self-esteem enhancement and for relief from decision-making and problem-solving responsibilities. Finally, patients' perceived prognosis but not the objective severity of their illness was associated with a heightened desire for support, especially for instrumental support functions.

Psoriatic arthritis in the hand.

Psoriatic arthritis is a polyarthropathy distinct from rheumatoid arthritis and associated with onychodystrophy and skin lesions. Patients present with stiffness, flexion and extension contractures, digital swelling, or painful joints. Psoriatic arthritis mutilans is a rapidly progressive osteolysis resulting in severe deformity. Radiographs reveal widened joint spaces with interphalangeal joint destruction, resorption of the distal tufts, and frequently spontaneous fusion. Surgery involves mainly salvage procedures to relieve pain or improve position, as the increase in motion obtained usually is limited.

The distribution of the infective larvae of sheep gastro-intestinal nematodes in soil and on herbage and the vertical migration of Trichostrongylus vitrinus larvae through the soil.

From May 1982 until September 1983 samples of soil and herbage were collected from a paddock grazed from May to October 1982, and for two short periods between May and July 1983, by sheep infected with gastro-intestinal nematodes. Few infective larvae were recovered from the soil although appreciable numbers of larvae were recovered from the herbage. Infective larvae of Trichostrongylus vitrinus in faeces buried in the soil of grass plots, at a depth of 10 cm, each month from April 1982 until March 1983, migrated on to the herbage at all times of the year, few remaining in the soil. The significance of the soil as a reservoir of infective larvae is discussed.

Observations on the bionomics of the free-living stages of Trichostrongylus vitrinus.

Eggs of Trichostrongylus vitrinus in faecal pellets deposited on grass plots each month from April 1981 to March 1982 developed into infective larvae. From October to March development was slow and mortality of the pre-infective stages was very high. From April to September development was more rapid. The weather was generally dry and mortality of the pre-infective stages was high on plots with short herbage but was lower on most of the plots with long herbage, especially in July and August. In the laboratory, development of eggs into infective larvae was completed at temperatures ranging from 4 degrees C to 27 degrees C in faecal pellets which were either kept moist or dried out slowly, but not in faecal pellets which dried out rapidly. The rate of development increased as the temperature rose. Infective larvae survived for up to 16 months on the herbage of grass plots; some survived during very cold weather in the winter of 1981/82. In the laboratory, infective larvae suspended in tap water survived even longer at 4 degrees C and 10 degrees C but not at higher temperatures. They were rapidly killed by continuous freezing. They survived for up to 8 weeks when subjected to desiccation. The relationship between climatic conditions and the development and survival of the free-living stages is discussed.

Observations on the effect of anthelmintic treatment on the transmission of Hyostrongylus rubidus and Oesophagostomum spp. among sows at pasture.

The transmission of Hyostrongylus rubidus and Oesophagostomum spp. following anthelmintic treatment was studied over a period of two years in a herd of sows kept out-of-doors on a commercial farm in south-eastern England. The sows were moved on to a clean pasture each autumn and at the same time were treated with an anthelmintic. The treatment was repeated six months later when the faecal worm egg count was rising. Contamination of the pasture with worm eggs was both light and intermittent. The pasture herbage remained free of infective larvae until the early summer; subsequently the herbage became lightly infected with larvae so that transmission of the parasites was possible, but limited. The level of infection on the herbage was much lower than was seen in earlier observations when the more commonly used system of treating groups of sows at different times of the year, in between farrowings, was used.

An evaluation of multiple trauma severity indices created by different index development strategies.

Evaluation of the effectiveness of emergency trauma care systems is complicated by the need to adjust for the widely variable case mix found in trauma patient populations. Several strategies have been advanced to construct the severity indices that can control for these population differences. This article describes a validity and reliability comparison of trauma severity indices developed under three different approaches: 1) use of a multi-attribute utility (MAU) model; 2) an actuarial approach relying on empirical data bases; and 3) an "ad hoc" approach. Seven criteria were identified to serve as standards of comparison for four different indices. The study's findings indicate that the index developed using the MAU theory approach associates most closely with physician judgments of trauma severity. When correlated with a morbidity outcome measure, the MAU-based index shows higher levels of agreement than the other indices. The index development approach based on the principles of MAU theory has several advantages and it appears to be a powerful tool in the creation of effective severity indices.

Observations on the development and survival of the free-living stages of Hyostrongylus rubidus both in their natural environments out-of-doors and under controlled conditions in the laboratory.

Faces containing eggs of Hyostrongylus rubidus were deposited on grass plots each month throughout 1980. Eggs in faeces deposited on plots from May to October developed into infective larvae but in May development was completed only in artificially moistened faeces, the weather was warm and dry and natural faeces dried out rapidly resulting in the death of eggs and pre-infective larvae. For the remainder of this period the weather was sufficiently warm and wet for development to be completed. More eggs developed into infective larvae on plots with well-grown herbage than on plots with short herbage. In April a few eggs survived and developed into 1st-stage larvae but no further development took place. In the laboratory development was completed at temperatures ranging from 10 to 27 degrees C but no development took place at 4 degrees C. Out-of-doors infective larvae survived on herbage for up to 10 months while in the laboratory, infective larvae suspended in tap water survived even longer to 10 and 22 degrees C, but the larvae were rapidly killed by continuous freezing and by desiccation when the relative humidity was less than 95%. The relationship between climatic conditions and the development and survival of the free-living stages is discussed and a comparison made with the free-living stages of Oesophagostomum dentatum.

Carcinoma in a transplanted nipple.

A 26-year-old woman requested that the nipple from her breast be saved for later reconstructive mammoplasty. At the time of mastectomy, two biopsy specimens from the base of the nipple showed no malignant neoplasms, The nipple was transplanted to the left thigh. Eleven months later, a 5-cm mass developed deep in the nipple transplant, and an adjacent inguinal lymph node became enlarged. Examination of biopsy specimens from the base of the nipple transplant showed the same duct cell carcinoma as the original specimen.

Observations on the development and survival of the free-living stages of Oesophagostomum dentatum both in their natural environments out-of-doors and under controlled conditions in the laboratory.

Eggs of Oesophagostomum dentatum in faeces deposited on grass plots from May to October developed into infective larvae. Warm wet weather facilitated development but weather conditions which caused the faeces to dry out rapidly resulted in a heavy mortality of eggs and pre-infective larvae. During the winter no development took place and the eggs died. In the early spring and late autumn a few eggs survived and developed into 1st-stage larvae but they died without developing further. In the laboratory no development took place at 4 degree C but at temperatures ranging from 10 to 25 degree C development into infective larvae was completed, the rate increasing as the temperature rose. Out-of-doors infective larvae survived in faeces and on herbage for 1 year under a wide range of climate conditions including the exceptionally cold winter of 1978--79. In the laboratory, infective larvae suspended in water survived even longer at temperatures ranging from 4 to 27 degree C. They were rapidly killed by continuous freezing and by desiccation when the relative humidity was less than 90%. The relationship between climatic conditions and the development and survival of the free-living stages is discussed.

Further attempts to immunise lambs using metabolites and in vitro grown larvae of Ostertagia circumcincta.

Attempts were made to immunise lambs by the intramuscular injection of either lyophilised or concentrated metabolites produced by Ostertagia circumcincta when grown in vitro, or macerated fourth and fifth stage worms. The lyophilised metabolites did not stimulate protection against the establishment of worms in nine-months-old lambs but the macerated worms and concentrated metabolites elicited protection in six-months-old and three-months-old lambs respectively. The worm burdens and worm egg counts of the immunised lambs were less than those of control lambs.

An automatic x-ray exposure controller for mammography.

A solid state sensor and associated electronic apparatus has been developed which automatically measures and controls film exposures when used with low-energy diagnostic equipment. When the kilovoltage is held constant, exposure is determined by the quantity of photons which reach the film, after passing through the breast. When the sensor is placed under the film, consistently good exposure density has been obtained. The design and installation of the sensor and exposure controller is presented.

Preliminary results using metabolites and in vitro grown larvae of Ostertagia circumcincta to immunise lambs against oral challenge.

An attempt was made to immunise lambs by the intra-muscular injection of concentrated metabolites obtained from the in vitro culture of Ostertagia circumcincta, by the oral administration of lyophilised metabolites or by the subcutaneous injection of living third, fourth and fifth stage worms grown in vitro. Protection appeared to have been elicited by each treatment as the worm burdens, the lengths of the worms and the faecal worm egg counts in the immunised lambs were less than those of the control lambs.

The significane of Nematodirus helvetianus eggs which have survived on a pasture throughout the winter in the transmission of infection to calves.

A field experiment was carried out to determine the significance of Nematodirus helvetianus eggs which had survived throughout the winter in the transmission of infection to calves turned on to a pasture in the early summer. The calves became infected but did not exhibit symptoms of clinical disease. It was concluded that eggs which survive the winter are unlikely to be associated with outbreaks of disease.
