The impact of glaucoma on the quality of life of patients in Norway. II. Patient response correlated to objective data

PURPOSE: To elucidate the relationship between the visual difficulties reported by patients treated for glaucoma and their objective functional damage, and to evaluate the reliability of the patient responses. METHODS: Questionnaires concerning quality of life filled in at home by 589 patients treated for chronic open angle glaucoma were correlated to corresponding questionnaires returned from their ophthalmologists. RESULTS: Few of our patients had a visual field damage judged to be of functional significance. There was a weak to moderate association between both visual field defects and decreased visual acuity and self-reported visual difficulties. A high proportion of the patients had normal binocular visual field and a stable disease, raising the suspicion that some of them were treated for ocular hypertension. The agreement between the responses from the patients and the ophthalmologists concerning the topical treatment was good, regarding treatment duration and other diseases of the patients the agreement was moderate. CONCLUSION: The association between subjective visual disability and presence of visual field defects was weak to moderate in our patients treated for glaucoma, and this association was further weakened by adjusting for visual acuity. Some patients might be treated unnecessarily, and a favourable prognosis might be given to most of them. The reliability of the patients in general was good.     

Self-Injury in Adolescents With Eating Disorders: Correlates and Provider Bias

IntroductionSelf-injurious behavior (SIB) is common among adolescents, and has been shown to be associated with eating disorders (ED). This study examines the prevalence of SIB and SIB screening in adolescents with ED, and associations with binge eating, purging, and diagnosis.MethodsCharts of 1,432 adolescents diagnosed with ED, aged 10–21 years, at an academic center between January 1997 and April 2008, were reviewed.ResultsOf patients screened, 40.8% were reported to be engaging in SIB. Patients with a record of SIB were more likely to be female, have bulimia nervosa, or have a history of binge eating, purging, co-morbid mood disorder, substance use, or abuse. Patients who engaged in both binge eating and purging were more likely to report SIB than those engaged in restrictive behavior or either behavior alone. Providers documented screening for SIB in fewer than half of the patients. They were more likely to screen patients who fit a profile of a self-injurer: older patients who binge, purge, or had a history of substance use.ConclusionsSIB was common in this population, and supports extant literature on associations with bulimia nervosa, mood disorders, binge eating, purging, abuse, and substance use. Providers may selectively screen patients.     

Medical versus surgical treatment of unstable angina

Unstable angina is an important symptom of coronary artery disease. Two general clinical presentations may occur: (1) stable angina with a recent increase in severity or angina of recent onset, or (2) acute coronary insufficiency or angina at rest with chest pain resembling that of acute infarction. The risk of death or infarction is greater in patients who have recurrent chest pain and ST-T wave abnormalities despite hospital treatment. In patients without electrocardiographic or serum enzyme evidence of a completed infarct, coronary arteriography and bypass graft surgery can be performed with an acceptably low mortality rate. Surgical treatment provides better symptomatic relief than medical management in many patients, but the significant incidence of perioperative infarction makes it difficult to determine if surgery prevents infarction. Some studies indicate that surgery improves survival in subgroups, but data from large scale randomized studies will be needed to answer this question securely. Patients with disease of the left main coronary artery should probably have surgical treatment.Medical treatment will relieve symptoms in most patients with unstable angina and on a long-term basis may obviate the need for surgery. A preliminary period of intensive medical treatment before surgery may be advantageous since there is little evidence that survival rates are improved by treating unstable angina as an acute surgical emergency.     

Unstable angina: comparison of medical and surgical management.

Medical versus surgical treatment of unstable angina was compared in a prospective nonrandomized study of 118 patients. Acute transient ST-T wave changes were present during chest pain in all patients. Acute infarction was excluded by serial electrocardiograms and enzyme studies. All patients admitted to the coronary care unit from 1970 to 1975 who fulfilled the entry criteria were included in the study. The starting point for data evaluation was 5 days after hospital admission. Characteristics at entry were similar in 66 medically treated patients and 52 patients who had coronary bypass vein graft surgery. During a mean follow-up period of 23 months in 66 medically treated patients with unstable angina the incidence rate of nonfatal myocardial infarction was 17% and the total mortality rate 21 percent compared with respective rates of 19% and 5.8% in 52 surgically treated patients. In the surgical group 8 patients (15%) had a perioperative infarction and only 2 (4%) had a late infarction; one patient (2%) died at operation. Symptomatic improvement was observed more frequently in the surgically treated group. Sixty percent of surgically treated patients were free of angina compared with 21% of medically treated patients. Eight medically treated patients (12%) required late surgical treatment for persistent severe angina despite optimal medical management.     

Characteristics and outcome of medical nonadherers in the Veterans Administration Cooperative Study of Coronary Artery Surgery

During a 7-year follow-up period in the Veterans Administration Study of Bypass Surgery, 75 (24%) of 311 medically assigned patients without left main disease "crossed over" to surgical treatment. Nineteen baseline, clinical, electrocardiographic and angiographic characteristics of the 75 crossover patients were compared with those of the 236 patients who adhered to medical treatment. At entry into the study, the crossover group contained more patients with severe angina than did the medical adherers group (p less than 0.05) and fewer patients with electrocardiographic evidence of previous myocardial infarction (p less than 0.05). Other entry characteristics were similar in distribution among those in the medical-adherer and crossover groups. The 2 major reasons for crossover were persistence or progression of angina, which occurred in 43 and 37% of the 75 crossover patients, respectively. There was no relation between progression of symptoms and angiographic progression of coronary narrowing. Thus, crossover was not determined by more severe coronary narrowing, but was associated with more severe symptoms and a lower incidence of infarction. The medically randomized patients who later underwent surgery (medical "nonadherers") experienced the same relief of angina 1 year after surgery as did the surgically randomized patients who initially received surgery (surgical "adherers"); however, their overall 7-year survival was lower (77% for medical nonadherers vs 83% for surgical adherers; difference not significant).     

Acute coronary embolism complicating bacterial endocarditis: operative treatment.

A patient with bacterial endocarditis and no previous history of angina substained an acute anterolateral myocardial infarction while awaiting surgery. Selective coronary arteriography revealed a filling defect in the left anterior descending coronary artery with limited flow beyond the area of occlusion. A calcific embolus from the infected aortic valve was removed at the time of valve replacement, and the patient had an uneventful immediate postoperative course. Late postoperatively paravalvular aortic regurgitation recurred before and after a second repair.     

Ten-year incidence of myocardial infarction and prognosis after infarction. Department of Veterans Affairs Cooperative Study of Coronary Artery Bypass Surgery

BACKGROUND. The 10-year incidence of myocardial infarction (fatal and nonfatal) and the prognosis after infarction were evaluated in 686 patients with stable angina who were randomly assigned to medical or surgical treatment in the Veterans Administration Cooperative Study of Coronary Artery Bypass Surgery. METHODS AND RESULTS. Myocardial infarction was defined by either new Q wave findings or clinical symptoms compatible with myocardial infarction accompanied by serum enzyme elevations with or without electrocardiographic findings. Treatment comparisons were made according to original treatment assignment; 35% of the medical cohort had bypass surgery during the 10-year follow-up period. The overall cumulative infarction rate was somewhat higher in patients assigned to surgery (36%) than in medical patients (31%) (p = 0.13) due to perioperative infarctions (13%) and an accelerated infarction rate after the fifth year of follow-up (average, 2.4%/yr in the surgical group versus 1.4%/yr in the medical group). The 10-year cumulative incidence of death or myocardial infarction was also higher in surgical (54%) than in medical (49%) patients (p = 0.20). According to the Cox model, the estimated risk of death after infarction was 59% lower in surgical than in medical patients (p less than 0.0001). The reduction in postinfarction mortality with surgery was most striking in the first month after the event: 99% in the first month (p less than 0.0001) and 49% subsequently (p less than 0.0001). The estimated risk of death in the absence of infarction was nearly identical regardless of treatment (p = 0.75). Exclusion of perioperative infarctions did not alter the findings. CONCLUSIONS. Although surgery does not reduce the incidence of myocardial infarction overall, it does reduce the risk of mortality after infarction, particularly in the first 30 days after the event (fatal infarctions).
