PPVT-R as an estimate of premorbid intelligence in older adults.

The Peabody Picture Vocabulary Test-Revised (PPVT-R) was examined as an estimate of premorbid intelligence in a clinical sample of elderly patients (N = 150) undergoing clinical neuropsychological evaluation. PPVT-R standard scores were compared across grossly cognitively intact, mildly/moderately and severely impaired groups of patients, and compared to a short form of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Barona regression equation. Results indicate that, while the PPVT-R is vulnerable to increasing levels of cognitive impairment among patients with fewer years of education, the PPVT-R is stable across mild to moderate levels of impairment for patients with greater than 12 years of education. In a sub-sample of grossly cognitively intact patients (n = 91), the PPVT-R standard score correlated significantly with estimated WAIS-R FSIQ (r =.61). Compared to the Barona equation, the PPVT-R was less likely to over-estimate WAIS-R FSIQ in the grossly cognitively intact patients. These data suggest the PPVT-R to be a useful estimate of premorbid ability for patients with a greater than high-school education.

What happens to wild animals with broken bones?

Orthopaedic teaching suggests that long-bone fractures in wild animals are not uncommon and that they can heal naturally. This paper investigates this statement. The unsystematic collection of specimens for museums has perpetuated the idea that these fractures are not uncommon. Many fractures in adult skeletons seem to have occurred while the animal was still young. A review of the original skeletons in two museums does not support the view that major long-bone fractures in adult wild animals heal well. Contemporary observations on primates in the wild over long periods show that fractures of long bones in adult wild primates are rare and usually fatal, while falls which might be associated with juvenile fractures are much more common and may well be the source of the many well-healed fractures found in museum collections.

Orthopedic rehabilitation of the stroke patient.

Rehabilitation of hemiplegic patients begins with setting reasonable functional goals and a treatment plan to reach them. During the initial illness an effort is made to begin range of motion exercising and positioning to prevent contractures. Transfer from bed to chair is recommended as soon as the patient's general condition permits.Upper extremity function depends on sensory and motor function as well as visual and central cerebral impairment. Spastic symptomatic contracture of the shoulder must be prevented by adequate orthopedic management of any musculoskeletal problems such as arthritis or tendinitis and the initiation of an active exercise program. Surgical release of contractures is occasionally indicated in refractory cases. Elbow flexion and pronation flexion deformity of the forearm and hand have also required surgical release on occasion. The goal of lower extremity function is ambulation. A double upright short leg brace aids stability in gait. Long leg braces are not used but a cane may be necessary for balance assistance. Contractures must be prevented by an exercise program or surgically released.
