A practice pathway for the initial diagnostic evaluation of isolated sixth cranial nerve palsies.

PURPOSE: To define a practice pathway for the evaluation of sixth-nerve palsies (SNPs) and to determine its cost-effectiveness and validity in a retrospective chart review. METHODS: A Medline search of the English-language literature from 1966 to 1995 was performed to define the available clinical evidence and develop the practice pathway. The authors retrospectively reviewed 407 charts with the diagnosis of SNP seen at three centers. Information obtained included: etiologic diagnosis if known; development of new neurologic or ophthalmologic findings; and results and costs of neuroimaging studies, if performed. RESULTS: Of the 407 patients, 98 underwent computed tomography scans and 212 underwent magnetic resonance imaging of the head. Eighty cases were non-isolated, 317 were isolated SNP, and ten could not be classified from chart information. Of the 317 cases of isolated SNP, 49 were classified as traumatic; 5, congenital; 158, vasculopathic; 63, nonvasculopathic; and 42, progressive or unresolved. Following the recommendations of the practice pathway, the 158 patients classified as having vasculopathic SNP would not have undergone neuroimaging studies, realizing a savings of $100,000 in this study population of 407 patients. CONCLUSION: The recommendations of the practice pathway are supported by review of the literature and the retrospective review of these cases. However, a prospective study with a matched control group is needed to demonstrate regional and specialty-specific variations in care and to strengthen the clinical certainty of the pathway recommendations.

[Frequency of allergens in immediate, late, and dual allergic skin response at the National Institute of Pediatrics].

We studied 126 children with allergic illness in Instituto Nacional de Pediatria. We applied cutaneous test to determine the early, late and dual response. The results were 68% for the early response, 6% late response and 26% dual response. The allergens more frequently found in the early and late response were Dermatophagoides pteronyssinus, Dermatophagoides farinae and house dust. Approximately the third part of the children studied presented late cutaneous response (dual response more isolated late response). It is important to make the evaluation of the late response in patients with allergy disease for a good etiologic diagnosis.
