The longitudinal development of a rehabilitation agency: an integrated rehabilitation service delivery model.

Health care services in the late 1980's are undergoing drastic changes. Similarly the laws, insurance regulations, etc. are changing so rapidly that the health care system appears to be having a difficult time keeping up with the ever changing needs of the consumers (that is, the patients). Diagnosis Related Groups (DRGs) have resulted in decreased hospital stays for patients with subacute and chronic conditions, and therefore patients are being care for in outpatient rehabilitation agencies, and/or outpatient clinics associated with hospitals. In short, a patient cannot stay in the hospital unless he or she is acutely ill or in need of surgery. Outpatient care is gradually becoming more important since patients who would have still been in the hospital several years ago, are now released to go home, with an order to receive outpatient therapy at the local rehabilitation agency. Currently there is no model available for starting an outpatient rehabilitation agency, and as a result health care professionals interested in starting such a facility have no guidelines or methodology for establishing a private rehabilitation practice.

Computed tomographic findings in metastatic dural carcinomatosis.

A case is presented of metastatic dural carcinomatosis associated with a thickened subdural membrane similar to those found in association with posttraumatic chronic subdural hematomas. In this case burr-hole drainage was attempted as a result of findings on computed tomography scanning that suggested a right frontal chronic subdural hematoma. However, no chronic subdural hematoma or effusion was found. The pathology, radiographic findings, and clinical features of this phenomenon are discussed.

Elastofibroma arising in the foot.

Elastofibroma is a nonneoplastic proliferation of collagen and abnormal elastic fibers, with a marked predilection for the subscapular area. We have described an elastofibroma occurring in a previously unreported location, the plantar surface of the foot. Trauma has been implicated in the pathogenesis of these lesions, regardless of site, and our patient's history of intensive dance and aerobic exercise further supports this relationship. Although elastofibromas are rare, they may be considered in the differential diagnosis of fibrous lesions arising at sites of repetitive strenuous exercise or injury.

Ultrasound effects on electroneuromyographic measures in sensory fibers of the median nerve.

The purpose of this study was to clarify the available literature and study the influence of ultrasound on the conduction velocity and amplitude of evoked sensory potentials in the median nerve. Thirteen subjects were assigned to either Experimental or Control Groups for ultrasound or placebo treatments. We compared sensory-nerve conduction velocity in the median nerve after 10 minutes of ultrasound treatment at three intensity levels (0.5, 1.0, and 1.5 W/cm2) with sensory-nerve conduction velocity in the median nerve after 10 minutes of placebo ultrasound treatment (0.0 W/cm2). No significant differences were noted between groups at any of the three ultrasound intensity levels, nor were the interaction effects significant. A hypothetical model, based on the available literature, proposes that ultrasound-induced changes in sensory-nerve conduction velocity may not progress in a direct linear fashion relative to the duration of treatment.

A statistical comparison of the emotional status of hospitalized versus nonhospitalized subjects: a pilot study.

It has been suggested that the health care system might be best assessed by the patient's own attitudes concerning the quality of service rendered (Wood, 1974). The purpose of this study is to analyze the psychosocial quality of the health service/hospital system in the greater Iowa City, Iowa area, and the relative emotional stability of hospitalized patients in several local hospitals. Specifically, a survey of 20 questions has been developed to assess (1) patient's attitudes and psychosocial outlook, (2) patient's self-perception. (3) situation generated feelings and (4) family/support group generated feelings. The comparative results of this experiment may indicate (1) the overall emotional status of hospitalized patients relative to non-hospitalized individuals and (2) the general psychosocial effectiveness of the hospital system (in the greater Iowa City. Iowa area). This information may be useful to both the medical/allied-health student and the inexperienced clinician, relative to various preconceived notions concerning the emotional state of hospitalized patients, in general.

The characteristics of physical exercise programs in rehabilitation: a means of analysis.

The relatively few number of articles available concerning the utility of physical exercise or physical sports activities within rehabilitation, according to a recent literature search, may reflect a general scarcity of such articles and/or programs. According to the 115 references located however, exercise appears potentially useful as a rehabilitation tool, in spite of various programmatic and methodological complications. It is apparent that all forms of exercise training are not suitable for all rehabilitation clients. However, based on the rehabilitation-related characteristics of the 15 different activities represented herein, there are certain forms of physical exercise which (1) are more congruent with normalization principles, (2) are more easily adapted to all disabilities, including the elderly, and (3) employ brief, high-intensity training principles, and therefore seem to be well suited for rehabilitation programming, in general. The anecdotal and empirical reports represented in this literature analysis should provide a base for continued investigation of the rehabilitative impact and relative efficiency of physical fitness/sports activities upon impaired individuals.

The influence of physical fitness training as a rehabilitation tool.

Many people have reported the benefits derived from physical exercise. Various activities of modern society reflect, in general, an increased interest in health and physical fitness. The construct validity of a "sound body - sound mind" philosophy, although not yet established, has been empirically supported within the nondisabled population. At first glance, a group of rehabilitation-related studies seem to further support such a theoretical construct, with regard to the physically, psychologically and/or emotionally impaired. A two-fold, programmatic and methodological, analysis of these 10 articles, which were (1) published between 1973 and 1978 and (2) were empirical studies of the effects of physical fitness training on disabled clients, uncovered a fascinating confounding of programmatic and methodological variables. Further empirical investigation of the issue utilizing (1) strong design methodology and (2) brief-high intensity training principles, is essential before any specific conclusions can be made, concerning the influence of physical fitness training upon rehabilitation clients. On the basis of the aforementioned 10 articles, however, exercise training appears potentially useful as a rehabilitation program tool.

Safety evaluation of gentian violet for breeder chickens.

Four treatment levels (1.0, 2.5, 5.0 and 10.0 x the recommended use level) of a gentian violet premix (Dye-Gen) were compared with non-medicated controls for breeder chickens during a 168-day study. There were no treatment effects up to and including 10 x the recommended use level on: average daily feed consumption, feed/dozen eggs, hatchability of fertile eggs, or mortality. Fertility was higher for the birds receiving 2.5 x the recommended use level than for the non-medicated controls. Egg production was higher (P less than .05) for the non-medicated controls and 10x groups than for the birds receiving the gentian violet premix at 2.5 x the recommended use level. Semen of breeder males was observed for % abnormal sperm, % dead sperm, % motility, vigor, and semen volume. There was no treatment effect on any of the semen characteristics evaluated. It can be concluded from these data that the gentian violet premix is safe for breeder chickens under the conditions of this study.

Fibroinflammatory pseudotumor of the submandibular gland.

BACKGROUND: Fibroinflammatory pseudotumors infrequently involve the major salivary glands. Much more is known regarding the clinical behavior of orbital pseudotumors, especially their steroid responsiveness. METHODS: A case of fibroinflammatory pseudotumor involving the submandibular gland is presented with its preoperative cytologic and computed tomographic scan features. The lesion had a dramatic response to steroids for residual disease. CONCLUSIONS: If preoperative cytologic features of benign spindle cells with an inflammatory component seen on fine-needle aspiration raise the possibility of fibroinflammatory pseudotumor, then responsiveness to high-dose steroids may preclude the need for more-extensive surgery.
