The impact of outpatient drug services on abstinence among pregnant and parenting women.

Although there is an increasing number of outpatient drug programs, there remains little consensus on which service components are most effective for pregnant and parenting women seeking treatment. In this investigation, we studied 48 women who remained in treatment for 5 consecutive months to: (1) examine differences between clients who maintained 30 to 90 days of abstinence and those who did not and (2) test the association between services and abstinence. Although we found no demographic differences between abstinent and nonabstinent women, we did find that significantly more abstinent women received family therapy services compared to nonabstinent women as they remained in treatment. Furthermore, we found that clients who were abstinent tended to receive more services overall than those who were not. Providers need to consider their population when deciding on which service components will be included: and family therapy is one service component that should be available to pregnant and parenting women.

Cholera toxin mapping of retinal projections in pigeons (Columbia livia), with emphasis on retinohypothalamic connections.

Anterograde transport of cholera toxin subunit B (CTb) was used to study the retinal projections in birds, with an emphasis on retinohypothalamic connections. Pigeons (Columbia livia) were deeply anesthetized and received unilateral intraocular injections of CTb. In addition to known contralateral retinorecipient regions, CTb-immunoreactive fibers and presumptive terminals were found in several ipsilateral regions, such as the nucleus of the basal optic root, ventral lateral geniculate nucleus, intergeniculate leaflet, nucleus lateralis anterior, area pretectalis, and nucleus pretectalis diffusus. In the hypothalamus, CTb-immunoreactive fibers were observed in at least two contralateral cell groups, a medial hypothalamic retinorecipient nucleus, and a lateral hypothalamic retinorecipient nucleus. To compare retinorecipient hypothalamic nuclei in pigeons with the mammalian suprachiasmatic nucleus, double-label experiments were conducted to study the existence of neurophysin-like immunoreactivity in the retinorecipient avian hypothalamus. The results showed that only cell bodies in the medial hypothalamic nucleus contained neurophysin-like immunoreactivity. The results demonstrate CTb to be a sensitive anterograde tracer and provide further anatomical information on the avian equivalent of the mammalian suprachiasmatic nucleus.

Use of power Doppler in pediatric neurosonography: a pictorial essay.

In pediatric neurosonography, conventional color Doppler imaging has been the primary adjunct to routine gray-scale imaging. Power Doppler sonography is a relatively recent development that does not have the limitations of conventional color Doppler ultrasound. The power Doppler technique measures the energy of moving red blood cells instead of the velocity and direction of flow. Advantages of this technique include increased sensitivity for identifying flow in slow-flow states, more complete evaluation of a vessel, and more accurate evaluation of the course of the vessel. Power Doppler sonography is helpful in evaluation of the neonatal brain in a variety of clinical situations: identifying the exact locations of extraaxial fluid collections, differentiating intraventricular clot from normal choroid plexus, detecting intraventricular hemorrhage, and demonstrating asymmetries in cerebral perfusion. However, in certain difficult cases, use of both conventional color Doppler sonography and power Doppler sonography produces increased diagnostic accuracy because these techniques furnish complementary information.

Growth response to enteral feeding by children with cerebral palsy.

This study evaluated the growth of 51 children with cerebral palsy after the initiation of enteral tube feedings. The children were divided into three groups according to how soon after their central nervous system (CNS) insult they were started on enteral feedings. Group 1 consisted of 14 children who were within a year of their CNS insult; they were underweight for age, but had normal length as well as weight for length. Within 6 months of initiating enteral tube feedings, most children in this group had normalized their weights. Group 2 consisted of 27 children who were within 8 years of their CNS insult; they were stunted and were underweight for both their age and their length. Within 6 months of initiating enteral feeds, the group increased both weight and weight for length to near normal, but their gains in length reached a plateau at 90% of ideal for age. Group 3 consisted of 10 children who were more than 8 years after their CNS insult. This group was severely malnourished but had some improvement in their weight for age and for length but, length for age showed no significant change. We conclude that the earlier adequate nutritional management of children with severe cerebral palsy is initiated, the more readily the nutritional deficits will reverse.

Self-administration of drugs on an oncology ward.

This article focuses on the development of a programme of self-administration of medicines within an oncology setting. Previous studies which have developed this concept demonstrate that such a programme has a positive impact on a patient's knowledge of his/her illness and treatment. Compliance with drug regimens increases and patients are given back control over one aspect of their lives while in hospital. The development of an individualized drug administration programme within an oncology unit and how it will be evaluated in the future are described.

Workplace adjustment and intergenerational differences between matures, boomers, and xers.

The authors explored the factors influencing occupational adjustment related to workplace stress among 413 nurses at a Midwestern pediatric hospital. Among critical factors found in responses to their questionnaire and follow-up focus groups were differences in work adjustment and intergenerational conflicts. Both real and perceived workplace stress can manifest itself both fiscal and human costs by increasing turnover, absenteeism and worker's compensation claims as well as "faulty products and negative behaviors." Baby boomers (those born between 1946 and 1964) and Generation Xers (those born between 1965 and 1981) reported quite different issues and perceptions of occupational stress.
