Measurement of the rate of aqueous humor flow.
Techniques which estimate the rate of aqueous flow generally require the use of tracer substances. Determination of the distribution of the tracer in the relevant body compartments permits calculation of the rate of flow within the limits of accuracy of the method used. The underlying theory, as well as the advantages and limitations of methods employing systemic, topical, intracameral, and intravitreal administration of tracer substances are reviewed. Since these methods all assume that the rate of aqueous secretion is constant, yet the presence of a diurnal rhythm of flow has been demonstrated in both rabbits and humans, a compartmental model of a circadian system based upon the vitreous depot technique is presented. This model estimates the degree to which a continuously changing rate of aqueous flow limits the ability to determine aqueous flow rate accurately by this particular method and illustrates this limitation, which is common to all tracer methods.

Planning change in scheduling practices: a theoretical perspective.
The dynamic nature of today's health care environment requires innovation and creativity in organizational structure and management style. Some of the most essential concerns of nursing staff today are related to quality of working life, and perhaps a central focus for most nurse employees is a scheduling system which offers the flexibility necessary for them to respond to an active personal and professional life. This paper describes the utilization of change theory in operationalizing new scheduling practices with four unique nursing groups. The self designed master rotation and a self scheduling process are two examples of innovative change implemented by four nurse managers. Each participative management approach is presented in relation to the phases of Lewin's change process. Strategies include a needs assessment survey, facilitating staff participation in the design, implementation and evaluation of a new scheduling practice and encouraging group responsibility for the process and outcome of the planned change.

Review of postoperative results of the subtalar arthrorisis operation: a preliminary study.
The purpose of this paper is to report the preliminary results of a follow-up study of the subtalar arthrorisis operation for the correction of flexible flatfoot. It is the authors' intention to report the efficacy of this surgical procedure in restoring the flexible flatfoot to normal function.

Computerized topography of a full-thickness corneal laceration.
A full-thickness corneal laceration was studied by computerized topography. Measurements taken preoperatively and during healing allowed the effects of the injury, its repair, and subsequent suture removal to be isolated and separately analyzed.

Fatigue perturbation of the os calcis.
This paper represents a philosophical shift in thinking. The authors propose that heel spur syndrome is not a primary soft tissue injury (i.e., enthesiopathy with concomitant bruising of the bursae and fat pad, and eventually the formation of a traction spur by the pull of the plantar fascia), but rather a primary bone injury. A microtrabecular stress failure (fatigue perturbation) of the os calcis occurs with secondary soft tissue involvement such as enthesiopathy, periostitis, myositis, bursitis, and finally the formation of a buttress callous (bone spur) to stabilize a microcortical crack. This study describes four stages in a progressive, sequential, pattern of fatigue failure of the os calcis. Clinical symptoms for each stage, along with supporting data such as x-rays, bone scans, and MRIs will be presented, as well as a suggested treatment plan for the chronic resistant cases.

Lipoblastoma presenting as a mesenteric mass in an infant.
PURPOSE: This article describes an infant with a large abdominal mass and hypertension. PATIENT AND METHODS: A 5-month-old infant girl with diarrhea of 1 week's duration and a large right-sided abdominal mass was brought for treatment. Computed tomography of the abdomen revealed a large, generally homogeneous, hypodense mass, which compressed the right kidney, resulting in dilatation of the right renal collecting system. At surgery, the mass was adherent anteriorly to the transverse colon and attached by a stalk to the mesentery near the origin of the right colic artery. RESULTS: Examination of the mass showed an encapsulated lipoblastoma. Cytogenetic analysis revealed a 46,XX karyotype with a reciprocal translocation between chromosome 2 and chromosome 8 with breakpoints at q23 and q11.2, respectively. CONCLUSION: Lipoblastoma is a rapidly growing but benign tumor, which can cause severe medical problems by compressing major organs. Cytogenetic analysis can reveal translocations involving chromosome 8 band q11.2, which appears to be a specific chromosome marker for lipoblastoma.
