Health promotion for older adults.

In light of the growing numbers of older persons, exponential increases in chronic health conditions, and rising health-care costs, our society is pressed to explore new strategies for maintaining and improving health in the later years. Studies have found that positive lifestyle changes can have an impact on the health status at any age, and can help to manage, postpone, and even prevent certain chronic health conditions. Several "model" health promotion programs designed specifically for older persons have demonstrated effectiveness in this area. This article proposes that health promotion for older adults should be taken seriously as an approach to managing chronic illness and mitigating high health-care costs in an "Aging Society."

Management of adults with cystic fibrosis.

Many patients with cystic fibrosis now survive into adulthood seeking continuation of their care from adult physicians rather than paediatricians. Attention to detail is the key to successful management of this complex multisystem disorder; care is best provided in the context of a multidisciplinary, team-oriented approach.

Spasmodic torticollis: a case report and review of therapies.

BACKGROUND: Spasmodic torticollis is a movement disorder of the nuchal muscles, characterized by tremor or by tonic posturing of the head in a rotated, twisted, or abnormally flexed or extended position or some combination of these positions. The abnormal posturing of the head allows this disorder to be clinically diagnosed. Psychiatric symptoms frequently accompany or precede the diagnosis of the movement disorder. METHODS: Using the key words "torticollis," "spasmodic torticollis," "therapy," "behavior therapy," "botulinum toxin," MEDLINE was searched from 1989 to 1996 for information on the cause and treatment of spasmodic torticollis. RESULTS AND CONCLUSIONS: Therapies include behavior modification, such as biofeedback, hypnosis, or simply training the patient to consciously readjust the position of the head; pharmacotherapy, using a variety of agents, the most commonly prescribed being anticholinergic medications or the botulinum toxin type A; and surgery, which entails selectively denervating the muscles responsible for the abnormal movement or posture of the head. The most effective treatments include surgery and botulinum, with sustained success rates ranging from approximately 60 to 90 percent.

Lipoblastoma presenting as a mesenteric mass in an infant.

PURPOSE: This article describes an infant with a large abdominal mass and hypertension. PATIENT AND METHODS: A 5-month-old infant girl with diarrhea of 1 week's duration and a large right-sided abdominal mass was brought for treatment. Computed tomography of the abdomen revealed a large, generally homogeneous, hypodense mass, which compressed the right kidney, resulting in dilatation of the right renal collecting system. At surgery, the mass was adherent anteriorly to the transverse colon and attached by a stalk to the mesentery near the origin of the right colic artery. RESULTS: Examination of the mass showed an encapsulated lipoblastoma. Cytogenetic analysis revealed a 46,XX karyotype with a reciprocal translocation between chromosome 2 and chromosome 8 with breakpoints at q23 and q11.2, respectively. CONCLUSION: Lipoblastoma is a rapidly growing but benign tumor, which can cause severe medical problems by compressing major organs. Cytogenetic analysis can reveal translocations involving chromosome 8 band q11.2, which appears to be a specific chromosome marker for lipoblastoma.
