Who helps whom in older parent-child families.

While previous research has assumed that older persons who live with adult children do so because of their poverty or disability, some recent evidence suggests that many of these extended households primarily benefit the child. This article attempts to provide a better understanding of the relative contributions of parents and adult children who live together through detailed analysis of data from the Survey of Income and Program Participation (SIPP). We find unmarried children tend to benefit more from and contribute less to extended households than married children. Similarly, unmarried parents benefit more from living with children than married parents. Results of logistic regression show that financial need and need for assistance with activities of daily living wre important determinants of coresidence for both unmarried children and unmarried parents. Controlling need, racial and ethnic minorities were more likely to live in extended families than non-Hispanic Whites.

Feathered nest/gilded cage: parental income and leaving home in the transition to adulthood.

The growing study of leaving home in young adulthood in the United States has been hampered by data and measurement problems, which are producing a major theoretical confusion about the role of parental resources in influencing young adults' leaving home. Does high parental income retain young adults in the home or subsidize their leaving (and parental privacy)? This paper uses the 1984 panel of Survey of Income and Program Participation to clarify this issue, and shows that the effects of parental resources differ depending on the route out of the home under consideration (marriage or premarital residential independence). Effects change substantially over the nest-leaving ages, but relatively few differences are found between young men and young women.

Optic disc edema after bone marrow transplantation. Possible role of cyclosporine toxicity.

Bone marrow transplantation has become widely used in the treatment of aplastic anemia and leukemia. Cyclosporine is used as prophylaxis against graft-versus-host disease. The authors report on eight cases of optic disc edema in patients taking cyclosporine after allogenic bone marrow transplant. Thorough evaluation revealed a possible alternate cause in two cases. In all cases, the optic disc edema resolved after discontinuing or decreasing the cyclosporine. Although cyclosporine has not previously been associated with optic disc edema, it has been implicated as the cause of a variety of neurologic side effects. Bone marrow transplant patients taking cyclosporine should be followed for the development of optic disc edema.

Disability, residential mobility, and changes in living arrangements.

The extent of mobility and changes in living arrangements associated with disability were studied using data from the 1984-86 Longitudinal Study of Aging. It was hypothesized that persons with significant limitations in their ability to perform normal daily activities (ADLs and IADLs) in 1984 would be more likely to move, more likely to be living with others in 1986, and more likely to have entered an institution between 1984 and 1986 than those without limitations. When only those variables that were measured in 1984 were used as predictors, this turned out to be true for institutionalization and for living with others in 1986. However, among those remaining in households, residential mobility showed little relationship to disability when other variables were controlled. When the change in disability between 1984 and 1986 was added to the prediction equation, there were strong relationships between changes in disability and both residential mobility and adjustment in living arrangement, suggesting that people respond quickly to significant changes in disability. However, because we cannot be sure that the changes in disability preceded the mobility or changes in living arrangements, we cannot claim to have established a causal link between these events.

Posterior chamber IOL implantation with suboptimal posterior capsular support.

A posterior chamber intraocular lens (PC/IOL) was implanted in 24 patients with suboptimal posterior capsular support due to preoperative or intraoperative rupture of the posterior capsule or zonules in which at least six clock hours of peripheral zonular support remained. The PC/IOLs were implanted, with ciliary sulcus haptic placement, with special attention to sulcus fixation of the haptics over the zone of residual zonular support. All of the IOLs have remained centered after a mean follow-up 10.5 months. We conclude that a PC/IOL can be successfully implanted and its position maintained if at least six clock hours of peripheral zonules remain.

An evaluation of the population and development program in Egypt.

Previous rural surveys analyzing the impact of the Egyptian Population and Development Program on KAP variables (knowledge, attitudes, and practices of contraception) have produced mixed results. In 1982 a survey specifically designed to measure program impact contained refinements in questionnaire measurement, sampling, and analysis. Each refinement intensified the apparent program impact. Fertility itself still appears unresponsive, and attitudes toward family size have changed little, but marked differences between program and nonprogram areas in contraceptive knowledge, attitudes, and practice suggest imminent fertility declines in program areas.

Murine xenotropic type C viruses. IV. Replication and pathogenesis of ducks.

The xenotropic (X-tropic) mouse type C virus (MuLV) and its pseudotype of murine sarcoma virus (MSV) were inoculated into several fertilized developing Pekin duck eggs. The development of the duck embryos was substantially reduced in those receiving the X-tropic viruses compared to eggs inoculated only with tissue culture medium. Infections virus was isolated from some of the adult animals; in others, evidence for integrated virus sequences in the tissues was noted. No specific pathology was found in the ducks that received X-trophic MuLV alone, but one duck developed multiple fibrosarcomas when inoculated at birth with the X-tropic virus pseudotype of MSV. Two ducks receiving X-tropic MuLv had signs of haematopoietic disorders. In addition, more virus-inoculated animals had evidence of hepatitis and encephalitis than control ducks. Antibody production to X-tropic MuLv was present in several ducks inoculated with virus either in embryo or at birth. Absence of antiviral antibodies was noted in those animals whose tissue contained replicating virus. These studies confirm the observations with X-tropic virus in tissue culture. They demonstrate in vivo that avian species are susceptible to infection by the mouse X-tropic virus and that their fibroblasts can be transformed by the X-tropic MuLV pseudotype of MSV.

Pharmacotherapy of drug abusers: adjunctive psychopharmacologic management of nonopiate mixed substance abusers in an outpatient setting.

Conventional practice in treating nonopiate mixed substance abusers have avoided the use of pharmaceuticals because of the strong drug orientation of this patient population. The author's impressions are that this is a maladaptive treatment polarization, and that psychopharmacotherapy of this group of patients is not only sometimes useful but necessary for some individuals. Diagnostic syndromata and problems specific to this patient population are delineated along with our experience in pharmacotherapy.

The spectrum of orbital aspergillosis: a clinicopathological review.

Orbital aspergillosis is an uncommon but serious infection that may first present to the ophthalmologist. Usually arising from the paranasal sinuses, it may present in manifold ways within the orbit. Some presentations, such as optic nerve involvement, can respond to systemic corticosteroids, leading to delays in diagnosis and possibly iatrogenic potentiation of the infectious process. In this review, pertinent clinical and radiographic findings are discussed, and the literature is summarized. Classic approaches to therapy include local treatment, debridement, and systemic amphotericin B. We review novel approaches to treating orbital aspergillosis and detail a flow-chart for its management. Four patients from the spectrum of orbital aspergillosis are also described: initially presenting as an infection of an exenteration socket, a complex dacryocystitis, and optic nerve tumor, and post-operative periorbital swelling. Physicians should be familiar with the clinical spectrum of disease and the variable presentation of this infection, as early diagnosis and rapid institution of appropriate therapy are crucial elements in the management of invasive aspergillosis. In the neutropenic or otherwise immunocompromised patient, a high index of suspicion must be maintained as delays in diagnosis of fulminant aspergillosis may lead to overwhelming and rapidly progressive infection. Obtaining adequate diagnostic material for pathological and microbiological examination is critical. Newer methods of therapy, particularly itraconazole and liposomal amphotericin B, may be beneficial in selected patients.
