Relationships among an older adult's life review, ego integrity, and death anxiety.

The frameworks of Erikson (1963) and Butler (1963) were used to design this descriptive study that investigated the relationships among life review, ego integrity, and death anxiety in older adults. Three hypotheses were proposed: (a) the greater the life review, the higher the ego integrity; (b) the greater the life review, the lower the death anxiety; (c) the higher the ego integrity, the lower the death anxiety. The sample consisted of 115 female and male volunteers between the ages of 65 and 93. The participants filled out the Life Review Questionnaire, Adult Ego Development Scale, Death Anxiety Scale, Death Preparation Scale, and a Personal Information Sheet. Life review, while not positively correlated with ego integrity, was found to have a negative correlation with death anxiety. Also, religious subjects were found to be more prepared for death than those who did not practice. Implications for therapy and future research are discussed, as well.

Power to the portables.

Portable computing devices generally are classified into four categories: laptop, palmtop, notebook, and pen-based computers. If a portable unit weighs over eight pounds, call it a laptop. If a stylus is used to input data, call it pen-based or a pen computer. Palmtops frequently are electronic organizers or resources: Sharp's Wizard line stores appointments and addresses; Franklin's Med-Spell contains Stedman's medical dictionary. Notebooks often incorporate a QWERT keyboard, and sometimes include a pointing device. NEC's notebooks in 1988 were the first sub-laptop computers. According to a 1992 report from Market Intelligence Research Corp., Mountain View, Calif., 4.6 million sub-laptops were sold in 1991 for $2.6 billion. By 1998 the market may reach $25 billion. The report predicts that one sub-category of pen computers, which are designed to be held in one hand while information is input with a pen-like stylus, will prove most useful to the health-care industry. Pen tablets, as opposed to pen clipboards, use faster, more expensive processors, store more data, and "are expected to allow [caregivers] to carry full patient charting with them ... and allow information to be recorded directly to patient files." Sub-laptops are on-line in many healthcare facilities: Greenwich hospital, Stanford University Medical Clinic, Humana Hospital Audubon, Rancho Los Amigos Medical Center, and others.

Comparison of plastic/metal and leather/metal knee-ankle-foot orthoses.

Fifteen children with bilateral lower limb disability were fit alternately with plastic/metal (PM) and leather/metal (LM) knee-ankle-foot orthoses. Fit was maintained by periodic growth adjustments. Gait, activities of daily living, and subjective reactions were gathered for each orthosis type. Despite previous anecdotal reports and expert opinion to the contrary, no overall differences were found between the two types of orthoses. Several specific differences were revealed, however; most children preferred the PM orthoses, saying they were lighter and more easily donned and doffed; the PM orthoses also controlled hip and knee sagittal motion and foot valgus/varus during gait more effectively. Individual biomechanical, neuromuscular and psychologic attributes of the disabled child must be carefully matched with the technical attributes of each orthotic option to effect an optimal prescription.

Acceptability of the NYU Number 1 Child-sized Body-powered Hand. New York University.

The NYU Number 1 Child-sized Body-powered Hand was field tested on 24 children with below-elbow limb deficiency. Identical in size (14.4cm, four-knuckle circumference) and shape to the Systemteknik myoelectric number 1 size hand, this hand offers a new prescription alternative for very young children with upper-limb amputation. The participating children and prosthetic clinic teams reacted very favorably to the hand's appearance, function, and light weight. Maintenance reports during the three-month trial were primarily concerned with glove damage. Overall, the hand was received enthusiastically, and is now in commercial production.

Calcium dynamics: a model system approach.

A computerized model used to simulate calcium metabolism in growing chicks combines growth equations with differential equations that account for the amount and action of various components of the plasma calcium regulating subsystems--intestine, kidney and bone. These in turn are modulated by the calcium-regulating hormones: parathyroid hormone and 1,25-dihydroxycholecalciferol. Simulation with this model indicated oscillations in the plasma calcium concentration in growing chicks under normal dietary conditions. The oscillations diminish in amplitude and finally disappear when dietary calcium concentrations are either reduced or elevated. These oscillations, triggered by the perturbation imposed by growth, are the result of the dual action of parathyroid hormone on bone on the one hand and on intestinal calcium absorption via the 1,25-dihydroxycholecalciferol synthesizing system on the other and the difference in the response time between the two subsystems. Simulation also predicts that at high or low intakes of calcium, the capacity of the control systems is exceeded and oscillation in plasma. calcium diminish and finally disappear. Bone calcium, simulated for different calcium concentrations, mimics documented experimental results.
