Myoelectric and body-powered prostheses.

One hundred twenty below-elbow child amputees compared cosmetically identical myoelectric (MYO) and body-powered (BP) hands after wearing each for 3 months; 78% chose the MYO and 22% chose the BP. However, at 2-year follow-up, only 44% wore the MYO, 33% used a BP hand or hook, and 23% became nonwearers (NW). Eighty percent of children aged > or = 8 years used active prosthetic prehension for both the MYO and BP prostheses.

Basic mechanisms of pain.

It has been well established that pain reflects complex, linked neuroendocrine responses that go far beyond a sensory alarm system. Accordingly, there may be significant medical consequences of inadequate recognition or treatment of pain.

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.

Case report: myiasis--the botfly boil.

Cutaneous furunculoid myiasis arises from the infestation of skin or mucous membranes with dipterous larvae. Myiasis from the botfly Dermatobia hominis is a common parasitic disease of the tropics of Central and South America, and may present in the United States. With increasing travel by U.

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.

Cyclosporin A augments human platelet sensitivity to aggregating agents by increasing fibrinogen receptor availability.

Clinical use of cyclosporin A (CsA) has been associated with platelet hypersensitivity and an increased incidence of thrombotic and vasoactive events. The purpose of this study was (1) to confirm that CsA enhances platelet sensitivity to the soluble agonists, adenosine diphosphate (ADP) and epinephrine (EPI), and (2) to determine if this enhancement is mediated by alteration in the availability of platelet surface fibrinogen receptors, a final mediator of platelet activation. Mean log dose of ADP required to achieve complete second-wave platelet aggregation in vitro decreased from 1.

Immunofluorescence and electron microscopic findings in a congenital arrector pili hamartoma.

A congenital arrector pili hamartoma is a neoplasm that presents as multiple or solitary dermal nodules in a dermatomal distribution. To elucidate and clarify its histogenesis, a lesion derived from a 3-year-old boy was studied by light microscopy, indirect immunofluorescence, using antibodies against basal lamina constituents and against interstitial matrix components, and electron microscopy. In addition, a rabbit antibody specific for bovine smooth-muscle myosin was used.

Rheumatoid arthritis with forefoot reconstruction.

Rheumatoid arthritis is a systemic disorder affecting joints as well as organ systems. The disease sequellae may result in complete loss of functional capacity. Surgical intervention including reconstruction of the forefoot may provide the patient with the opportunity to return to more activities of daily life.
