Treatment of multiple sclerosis with interferon beta in clinical practice: 2-year follow-up data from the South Italy Mobile MRI Project.

This follow-up study assessed the 2-year clinical and magnetic resonance imaging (MRI) outcomes of patients with multiple sclerosis (MS) originally enrolled in an MRI study conducted at eight centres in south Italy (the South Italy Mobile MRI Project). Of the 597 MS patients recruited at baseline, 391 returned for the follow-up study. Of these, 363 provided 2-year clinical and MRI follow-up data, and 215 were still undergoing treatment with one of four interferon beta regimens: Avonex, 30 mcg intramuscularly once weekly; Betaferon, 250 mcg subcutaneously (sc) every other day; Rebif 22 mcg sc three times weekly (tiw; Rebif 22); or Rebif 44 mcg sc tiw (Rebif 44). Over the 2-year follow-up period, patients receiving the higher dose of Rebif were more likely to remain free from relapses [odds ratio (OR) = 2.23] and from developing both new T2 (OR = 0.15) and new T1 black hole lesions (OR = 0.22), when compared with patients in the Avonex group. Despite some limitations in the trial design, the results from this follow-up study provide helpful clinical and MRI data on the efficacy of interferon beta regimens in MS patients treated in the clinical setting.

Brain atrophy and lesion load in a large population of patients with multiple sclerosis.

OBJECTIVE: To measure white matter (WM) and gray matter (GM) atrophy and lesion load in a large population of patients with multiple sclerosis (MS) using a fully automated, operator-independent, multiparametric segmentation method. METHODS: The study population consisted of 597 patients with MS and 104 control subjects. The MRI parameters were abnormal WM fraction (AWM-f), global WM-f (gWM-f), and GM fraction (GM-f). RESULTS: Significant differences between patients with MS and control subjects included higher AWM-f and reduced gWM-f and GM-f. MRI data showed significant differences between patients with relapsing-remitting and secondary progressive forms of MS. Significant correlations between MRI parameters and between MRI and clinical data were found. CONCLUSIONS: Patients with multiple sclerosis have significant atrophy of both white matter (WM) and gray matter (GM); secondary progressive patients have significantly more atrophy of both WM and GM than do relapsing-remitting patients and a significantly higher lesion load (abnormal WM fraction); lesion load is related to both WM and even more to GM atrophy; lesion load and WM and GM atrophy are significantly related to Expanded Disability Status Scale score and age at onset (suggesting that the younger the age at disease onset, the worse the lesion load and brain atrophy); and GM atrophy is the most significant MRI variable in determining the final disability.

Analysis of the medical records in a pediatric emergency room.

A prospective evaluation of Pediatric Emergency Room records permitted analysis of major errors and of factors contributing to them. All records from July 1973 to June 1975 were reviewed daily by a board certified pediatrician using a previously established protocol. Patients had been seen by pediatric house staff from 4 PM to 8 AM on weekdays and from 8 AM to 8 AM on weekends and 25,907 records were reviewed. Errors were detected in 9.5 percent of these. The most common was an incomplete set of vital signs which accounts for 68 percent of all errors. Failure to arrange for appropriate follow-up care occurred in 16 percent of cases. Other errors ranged from two to four percent and included inadequate use of laboratory, incomplete physical examination, inappropriate diagnosis or therapy. Major omissions in the history were uncommon (1.3 percent). The frequency of errors was significantly greater at the start of each academic year (July to October), and at the start of each month (P<0.001). The errors occurred significantly more often at the first year level than the second year level (P<0.01). This study suggests a means of improving record keeping and house staff education, ie, attending-level supervision should be emphasized at the start of each month and academic year. Daily reviews of errors with the house staff as well as modification of chart design may bring about more complete patient evaluation and detailed recording of findings, diagnosis, and disposition.
