The caregiver reaction assessment (CRA) for caregivers to persons with chronic physical and mental impairments.

The development and testing of a multidimensional instrument to assess the reactions of family members caring for elderly persons with physical impairments, Alzheimer's disease, and cancer is reported. Forty items were administered to a sample of 377 caregivers of persons with physical impairments and Alzheimer's disease. Five dimensions of caregivers' reactions were identified through exploratory factor analysis. Using confirmatory factor analysis on an independent sample (N = 377), these dimensions were tested for factorial invariance across spouse and nonspouse caregivers and between caregivers of persons with cancer and those caring for persons with Alzheimer's disease. The subscales also had a high level of factorial invariance across a three-wave panel study (N = 185). The subscales appeared consistent with first order tests of construct validity.

Sonographic diagnosis of portal venous gas in two pediatric liver transplant patients with benign pneumatosis intestinalis. Case reports and literature review.

Pneumatosis Intestinalis (gas in the bowel wall) is uncommon in children and is associated with a number of clinical conditions most notably necrotizing enterocolitis in sick neonates. We observed portal venous gas on sonography and benign pneumatosis intestinalis on abdominal radiography in two children who had recently undergone liver transplantation. Asymptomatic portal venous gas and pneumatosis intestinalis has not been described previously in pediatric liver transplant patients. It is important to recognize the sonographic appearance of portal venous gas since sonography is the imaging modality most frequently utilized for monitoring the allograft post liver transplantation.

Improving nursing practice: the provision of equipment.

The quality of nursing care depends not only on the knowledge and skill of practitioners, but also on the equipment provided for their use. The availability and storage of urinary catheters was recorded in two "point prevalence" surveys in one District Health Authority. The numbers of catheters available in different locations were not related to the prevalence or "predicted incidence" of catheterized patients. The second survey documented evidence of improvements in practice, in particular a reduction in excessive and/or out-of-date stocks; a reduction in damaged stock; an increased availability of catheters with small balloons; and a greater awareness of those considerations important to a judicious choice of catheter for each individual patient. Equipment audits improve practice by raising awareness of clinical issues; by providing objective evidence of unnecessary expenditure; and by monitoring indirectly certain aspects of care such as the provision of standards and guidelines.

The specialty of gynecologic oncology as perceived by the public.

The purpose of this study was to obtain information about the public's awareness and perception of the discipline of gynecologic oncology. The marketing of cancer care and related services has resulted in substantial funding being allocated to market individual institutions. However, little has been done to educate patients to the fact that there are physicians specifically trained who possess special expertise in the care of specific types of malignancy. The members of The Division of Gynecologic Oncology at The Hospital of the University of Pennsylvania asked each new patient to complete an anonymous questionnaire hoping to learn more about her prior knowledge of the specialty of gynecologic oncology and her perceptions of our discipline. Presented is the analysis of the answers provided by the 200 participants. The conclusion is that the public in general is poorly informed of gynecologic oncology as a specialty and consequently may not be taking advantage of optimal cancer care already available. Thus, as a specialty we must institute programs to educate and enlighten patients.

Case report: liver adenomatosis presenting as multiple calcified masses.

Liver adenomatosis is a rare condition with only 14 cases reported. It is considered to be a distinct entity from liver adenoma. This is the first case in which calcification has been described. The differential diagnosis of multiple calcified lesions in the liver is discussed, and other features of liver adenomatosis.

A formula for predicting the risk of a positive second-look laparotomy in epithelial ovarian cancer: implications for a randomized trial.

OBJECTIVE: To develop a formula to predict the risk of a positive second-look laparotomy. METHODS: A retrospective review was performed on 89 patients who underwent second-look surgery following a complete clinical remission after cis-platin- or carboplatin-based chemotherapy. Logistic regression was used to develop a formula to predict the probability of a positive second look based on age, stage, grade of tumor, residual disease after initial surgery, and histologic type. RESULTS: We identified three groups based on estimated probabilities: low probability (0.25 or less), intermediate probability (0.26-0.74), and high probability (0.75 or more). The low-probability group had an 8% chance of a positive second look, the high-probability group had an 82% chance of a positive second look, and the intermediate-probability group had the correct outcome predicted only 61% of the time. Survival curves paralleled these results and were significantly different for each group. CONCLUSIONS: Using known prognostic factors, a formula can aid in implementation of a randomized clinical trial to test the efficacy of second-look laparotomy. This formula could exclude patients not suitable for randomization and give the investigator a better idea of the expected survival of various subgroups.

Self-perceived social function among disabled children in regular classrooms.

Disabled children represent an important "at-risk" group for emotional and behavioral problems. This study determined how they assess their own social function in regular classrooms and compared them with their able-bodied peers. School principals identified 60 visibly disabled children who were integrated into regular classes for at least 50% of the time. A comparison group of 56 randomly selected, same-gender classmates was identified. Children completed the Perceived Competence Scale and a classroom sociometric scale. Parents and teachers were asked to rate each child's social function. Disabled children rated themselves lower on physical competence (mean = 2.53 vs 2.92, p = .002) but not on social or cognitive competence. However, disabled children had fewer friends and scored lower on the classroom sociometric measure than did their able-bodied classmates (mean = 2.06 vs 2.39, p = .01). There was no difference between disabled and control children when social function was assessed by parents or teachers. For all children two variables were significantly associated with the child's self-perceived social competence: the child's self-perceived physical competence (R2 = .27) and the peer sociometric rating (R2 = .13). Teacher perception (R2 = .35) and self-perception (R2 = .10) of social function were most strongly associated with the perception of peers. In both cases whether the child was disabled contributed little to the observed association. These findings support the importance of peers in the successful social function of children and suggest that teachers can have an impact on how children are perceived by other children.(ABSTRACT TRUNCATED AT 250 WORDS)

A semi-automated method for breathing rate measurement in the mouse.

A semi-automated system of breathing rate measurement for the assessment of lung damage in mice has been developed. Based on the plethysmographic method, a BBC B microcomputer plus Torch CPM examines four plethysmographs at any given time, looking for periods of quiet breathing and measuring the breathing rate during rest. This requires both machine code and Microsoft Basic programs, linked using Microsoft Link 80. The results correlated closely with results obtained using the well-validated measurement of chart recorder assessed breathing rate. Using the computer method, up to 40 animals could be examined per hour.

Institutionalization of an elderly family member: reactions of spouse and nonspouse caregivers.

Although a prevalent clinical assumption is that the caregiver well-being improves following patient institutionalization, recent research challenges this assumption. In this article, the impact of patient institutionalization on the well-being of family caregivers is examined. Caregiver reaction, sense of general well-being and level of depression are compared pre- and postinstitutionalization and differences between spouse, adult child, and other caregivers are investigated.

Cognitive abilities and school performance of extremely low birth weight children and matched term control children at age 8 years: a regional study.

The intellectual, psychoeducational, and functional status of a regional cohort of extremely low birth weight (ELBW) survivors who weighed 501 to 1000 gm at birth (n = 143) and who were born between 1977 and 1981 was compared with that of control children born at term (n = 145) who were matched for gender, age, and social class. One hundred twenty-nine ELBW survivors (90%) were available; their mean birth weight was 839 +/- 124 gm and mean gestational age 27 +/- 2.1 weeks, and 48 of them weighed less than or equal to 800 gm at birth. Both ELBW and control groups were tested at a mean unadjusted age of 8 years; 113 of 129 ELBW children completed the full test battery, eight blind children had other tests, and eight were not testable. The mean Full Scale IQ (Wechsler Intelligence Scale for Children--Revised) was 91 +/- 16 for ELBW children and 104 +/- 12 for control children (p less than 0.0001). Between 8% and 12% of the ELBW group scored in the "abnormal" range (less than or equal to -2 SD) on the Wechsler IQ and subtests, compared with 1% to 2% of the control group. The ELBW group did less well on the reading, spelling, and mathematics tests (Wide Range Achievement Test--Revised less than or equal to -2 SD: ELBW = 20% to 28%; control = 3% to 10%). The motor performance of the ELBW group (Bruininks-Oseretsky Test of Motor Proficiency less than or equal to -2 SD: ELBW = 20%; control = 1%) and their visual-motor integration (Beery Developmental Test of Visual-Motor Integration less than or equal to -2 SD: ELBW = 21%; control = 6%) were also poorer. Exclusion of 19 ELBW children with neurologic impairments or an IQ less than or equal to 70 or both did not result in significant improvement in Wechsler or achievement measures. Approximately 15% of the ELBW cohort performed in the abnormal range on the Vineland Adaptive Behavior Scales, compared with none of the control group. Although approximately two thirds of the ELBW group were performing in the normal range on intellectual measures, comparison with the control group suggests that, as a group, ELBW children were significantly disadvantaged on every measure tested.

Knowledge and use of community services among family caregivers of Alzheimer's disease patients.

The number of people with dementia residing within the community is steadily increasing. Community services can alleviate the burdens experienced by families, but are used infrequently by families of dementia patients. Caregivers (N = 93) of dementia patients were surveyed regarding their knowledge and use of community services. The most frequently used services were family support groups and home health aides. Overall, service use was low despite high levels of perceived availability of services. Older and less educated caregivers had higher levels of uncertainty about service availability. Depressed caregivers were less likely to know about service availability. Implications for practice and research are presented.

Assessment of the attitudes of family caregivers toward community services.

Previous research has not taken into account the influence of attitudinal variables on the use of community services by dementia caregivers. The Community Service Attitude Inventory (CSAI) was developed to provide a measurement tool to further understanding of community service use by family caregivers. Testing of the CSAI revealed five distinct components of family attitudes toward use of community services.
