Preventive healthcare in women with multiple sclerosis.

The health maintenance of women with diverse disabilities and chronic disabling conditions has been neglected by medical professionals. Interest in their basic health promotion has been eclipsed by the narrowed focus on their underlying conditions. We surveyed preventive medical practices of 220 women with multiple sclerosis (MS). The objectives of this study were to evaluate the adequacy of preventive healthcare delivery for women with MS and to explore the adequacy of the detection, prevention, and treatment of osteoporosis in this high-risk population. Our survey revealed that 50% of the women do not get regular medical preventive checkups. Twenty-five percent do not have regular pelvic examinations, and 11% have not had a Pap smear within 3-5 years. In women over 40 years old, 52% do not have yearly mammograms. Risk factors for premature osteoporosis in our sample included impaired mobility (53%), corticosteroid use (82%), and vitamin D deficiency as a result of avoidance of sunlight. Despite these risks, 85% have never had bone density testing, 50% are not taking calcium supplements, and 71% are not taking vitamin D. Among the postmenopausal sample, 81% have never had bone density testing, 50% are not taking calcium supplements, and 70% are not receiving hormone replacement therapy (HRT). Only 1% are taking bone resorption inhibitors. The benefits of preventive healthcare and cancer prevention screening should be stressed to women with MS. Referrals should be facilitated by neurologists for dignified, knowledgeable examinations in fully accessible facilities. Osteoporosis prevention, screening, and treatment protocols must be part of the medical plan for all women with MS.

Suprascapular neuropathy related to the use of crutches.

A 41-year-old man with shoulder pain was found to have a suprascapular neuropathy. The nerve injury was believed to be secondary to improper crutch usage. The pathophysiology of this unusual cause of suprascapular neuropathy involves injury to the nerve due to exaggerated movements around the shoulder joint. Suprascapular entrapment neuropathy is another potential hazard of improper crutch usage. Therefore, properly fitted crutches and adequate crutch training are essential for the prevention of additional disability.

MRI in epilepsy.

A retrospective study was done of the MRI and CT scans of 267 consecutive patients sent for an evaluation of one or more seizures. 21% (57/267) of the MRI scans were abnormal. The CT scan was normal in 28% of these MRI documented abnormal cases. In an additional 10% of these cases, MRI was more specific than CT scan. CT was more specific in cases of calcification and abscess (7%). There was one case specific than CT scan. CT was more specific in cases of calcification and abscess (7%). There was one case of undetermined pathology in which CT was abnormal despite a normal MRI. The predominant abnormalities found on MRI included tumor, infarction and vascular malformation. MRI is more sensitive than CT in noting central nervous system pathology and lesions of potential therapeutic significance in patients with seizures.

MRI appearance of AIDS subacute encephalopathy.

A case of biopsy documented subacute encephalopathy of AIDS was evaluated by CT and MRI. CT scanning revealed ventriculomegaly and ill-defined nonspecific periventricular white matter hypodensities. MRI, however, demonstrated extensive unequivocal diffuse white matter disease as the cause of the ventriculomegaly. MRI findings in this patient support the preliminary suggestion that MRI is more useful than computed tomography (CT) in demonstrating AIDS subacute encephalopathy.

Magnetic resonance imaging examination of denervated muscle.

Denervated muscles due to lumbar radiculopathy, peroneal axonal neuropathy and hypoglossal neuropathy were studied with magnetic resonance imaging (MRI). Denervated muscle was clearly distinguished from normal muscle by its higher intensity signal. Comparison of the resulting signal intensity of the muscle using various imaging parameters suggests an alteration in water macromolecular binding. These preliminary findings indicate that MRI may be useful in the noninvasive in vivo diagnosis and study of the effects of denervation on muscle.
