Article: Diffuse large B-cell lymphoma of the ocular adnexal region: A nation-based study.
[show abstract] [hide abstract]
ABSTRACT: Purpose: To characterize the clinicopathological features of diffuse large B-cell lymphoma (DLBCL) of the ocular adnexal region. Methods: The present series of orbital and adnexal DLBCLs were found by searching the Danish Registry of Pathology between 1980 and 2009. Histological specimens were re-evaluated using a panel of monoclonal antibodies. Clinical files from all patients with confirmed DLBCL were collected. Results: A total of 34 patients with DLBCL of the ocular adnexal region were identified. Eighteen of the patients were men. The patients had a median age of 78 years (range 35-97 years). Ninety-seven per cent of the patients had unilateral ocular adnexal region involvement, and the orbit (76%) was the most frequently affected site. Nineteen patients (56%) presented with Stage I lymphoma. Of these, 18 were diagnosed with primary lymphoma. Four patients (12%) had Stage II, one patient (3%) had Stage III and ten patients (29%) presented with Stage IV lymphoma. The 5-year overall survival (OS) rate for the whole study group was 20%. The patients with Stage I lymphoma had a significantly better 5-year OS rate (28%) than patients in Stage II-IV (5-year OS rate, 9%). In Cox regression analysis, concordant bone marrow involvement and the International Prognostic Index (IPI) score were prognostic factors for OS. Conclusions: Diffuse large B-cell lymphoma of the ocular adnexal region is mainly prevalent in elderly patients. Most patients had unilateral orbital involvement. The overall prognosis is poor. Concordant bone marrow involvement and the IPI score were independent prognostic factors for mortality.Acta ophthalmologica 05/2012; · 2.44 Impact Factor -
Article: Short-term practice effects and variability in cognitive testing in a healthy elderly population.
[show abstract] [hide abstract]
ABSTRACT: Cognitive decline in the elderly is a subject of intense focus. However, there is a lack of consensus regarding definition of significant decline in connection with repeated testing and the interpretation of cognitive tests results must take into account the practice effect and variability in test performance. The aim of this study was to collect cognitive test results with repeated testing in an elderly healthy population. 161 healthy controls ≥60 years were included. Cognitive testing was performed upon entry into the study, at 1 week and 3 months. Practice effect was evaluated on 7 neuropsychological measures and reference values of clinically important changes were calculated according to z-scores above 1.96. Test scores improved significantly (p<0.05) in 2 of 7 measures between baseline and 2nd test and in 6 of 7 measures between baseline and 3rd test session. No significant correlation was found between magnitude of practice effect and age or educational status. Practice effect and variability in cognitive testing in the elderly are important to consider when evaluating changes in cognitive performance over a short period of time.Experimental gerontology 03/2012; 47(6):432-6. · 3.34 Impact Factor -
Article: Malignant lymphoma of the lacrimal gland: a nation-based study.
[show abstract] [hide abstract]
ABSTRACT: To characterize the clinicopathologic features of lacrimal gland lymphoma. All cases of lacrimal gland lymphoma from January 1, 1975, through December 31, 2009, were retrieved from The Danish Registry of Pathology. Histologic specimens were reevaluated using a panel of monoclonal antibodies. Clinical files from all patients with confirmed lymphoma were collected. Twenty-seven patients with lacrimal gland lymphoma were identified. Eight of the patients were men and 19 were women; the median (range) age was 69 (43-87) years. The distribution of lymphoma subtypes was as follows: extranodal marginal zone lymphoma, 10 (37%); follicular lymphoma, 5 (19%); diffuse large B-cell lymphoma, 4 (15%); mantle cell lymphoma, 3 (11%); chronic lymphocytic leukemia/small lymphatic lymphoma, 2 (7%); and unclassified B-cell lymphoma, 3 (11%). Twenty-two patients (81%) had stage I or II lymphoma, 1 patient (4%) had stage III lymphoma, and 4 patients (15%) had stage IV lymphoma. Patients with stage I or II lymphoma were treated with radiotherapy (15 [67%]), chemotherapy (3 [14%]), chemotherapy plus radiotherapy (1 [5%]), and surgery (3 [14%]). Patients presenting with stage III or IV lymphoma were treated with chemotherapy alone. Complete remission was observed in 23 of the patients (85%), although 12 (44%) of these had a relapse, independent of subtype, stage, or treatment. The 5-year overall survival was 70%. Malignant lymphoma of the lacrimal gland is relatively rare and is mostly prevalent in elderly women. The distribution of lacrimal gland lymphoma subtypes resembles that of lymphoma subtypes of the salivary glands. The majority of lacrimal gland lymphomas are low grade, and the prognosis is relatively good.Archives of ophthalmology 10/2011; 129(10):1275-80. · 3.86 Impact Factor -
Article: Apolipoprotein E genotype and cognitive dysfunction after noncardiac surgery.
[show abstract] [hide abstract]
ABSTRACT: Apolipoprotein E is important in recovery after neuronal damage. The epsilon4 allele of the apolipoprotein E gene has been shown as a risk factor for Alzheimer disease, poor outcome after cerebral injury, and accelerated cognitive decline with normal aging. The authors hypothesized that patients with the epsilon4 allele would have an increased risk of postoperative cognitive dysfunction (POCD) after noncardiac surgery. In a multicenter study, a total of 976 patients aged 40 yr and older undergoing noncardiac surgery were tested preoperatively and 1 week and 3 months after surgery with a neuropsychological test battery comprising seven subtests. POCD was defined as a decline in test performance of more than 2 SD from the expected. Apolipoprotein E genotypes were determined by blood sample analysis at a central laboratory. Multivariate logistic regression analysis with POCD as the dependent variable assessed presence of the epsilon4 allele (yes/no) and other possible risk factors. The epsilon4 allele was found in 272 patients. One week after surgery, the incidence of POCD was 11.7% in patients with the epsilon4 allele and 9.9% in patients without the epsilon4 allele (P = 0.41). Three months later, POCD was found in 10.3% of patients with the epsilon4 allele and in 8.4% of patients without the epsilon4 allele (P = 0.40). Multivariate logistic regression analysis did not identify the epsilon4 allele as a risk factor at 1 week (P = 0.33) or 3 months (P = 0.57). The authors were unable to show a significant association between apolipoprotein E genotype and POCD, but statistical power was limited because of a lower incidence of POCD than expected.Anesthesiology 11/2004; 101(4):855-61. · 5.36 Impact Factor -
Article: Postoperative cognitive dysfunction in middle-aged patients.
[show abstract] [hide abstract]
ABSTRACT: Postoperative cognitive dysfunction (POCD) after noncardiac surgery is strongly associated with increasing age in elderly patients; middle-aged patients (aged 40-60 yr) may be expected to have a lower incidence, although subjective complaints are frequent. The authors compared the changes in neuropsychological test results at 1 week and 3 months in patients aged 40-60 yr, using a battery of neuropsychological tests, with those of age-matched control subjects using Z-score analysis. They assessed risk factors and associations of POCD with measures of subjective cognitive function, depression, and activities of daily living. At 7 days, cognitive dysfunction as defined was present in 19.2% (confidence interval [CI], 15.7-23.1) of the patients and in 4.0% (CI, 1.6-8.0) of control subjects (P < 0.001). After 3 months, the incidence was 6.2% (CI, 4.1-8.9) in patients and 4.1% (CI, 1.7-8.4) in control subjects (not significant). POCD at 7 days was associated with supplementary epidural analgesia and reported avoidance of alcohol consumption. At 3 months, 29% of patients had subjective symptoms of POCD, and this finding was associated with depression. Early POCD was associated with reports of lower activity scores at 3 months. Postoperative cognitive dysfunction occurs frequently but resolves by 3 months after surgery. It may be associated with decreased activity during this period. Subjective report overestimates the incidence of POCD. Patients may be helped by recognition that the problem is genuine and reassured that it is likely to be transient.Anesthesiology 06/2002; 96(6):1351-7. · 5.36 Impact Factor
