Measuring intraocular pressure with the Pulsair 3000 and Rebound tonometers in elderly patients without an anesthetic

Purpose To evaluate the utility of the new Rebound tonometer for measuring intraocular pressure (IOP) in an unanesthetized eye; to test patient tolerance, measurement time, and accuracy compared with the Pulsair 3000 tonometer.Methods IOP was measured with the Rebound tonometer and the Pulsair 3000 tonometer without an anesthetic in 131 residents of two Finnish nursing homes. The measurement time and possible pain or discomfort experienced by the inhabitants was recorded.Results The mean differences in IOP readings between the two tonometers were 0.31 mmHg, SD 2.45 mmHg for the right eyes and 0.36 mmHg, SD 2.17 mmHg for the left eyes (P=0.28, multivariate analysis). The correlation constants between the tonometers were 0.84 (right eyes) and 0.80 (left eyes). The Pulsair 3000 caused more discomfort than the Rebound tonometer (36% vs 15%, P=0.01). With the Pulsair, 85%, and with the Rebound tonometer, 95% of the patients felt no pain (P= 0.14). Measurement of both eyes with the Rebound tonometer took less time (55±22 s vs 138±55 s, P<0.001). The mean difference was 82 s and the 95% confidence interval of the difference was 66–98 s.Conclusion Measurement of IOP with the Rebound tonometer without an anesthetic is a rapid and well-tolerated procedure. IOP readings of the two tonometers were within ±1 mmHg in 52.5% of the measurements and within ±2 mmHg in 71.7% of the measurements.Submitted as an abstract to the ARVO annual meeting, May 2002     

Potential case of gynecomastia in mummified remains of an early modern period northern finnish vicar

We report possibly the oldest evidence of gynecomastia in mummified human remains. Computed tomography was performed on the mummified remains of an early 17th century Northern Finnish vicar. The examination of the scans revealed large bilateral subareolar irregular masses resembling female mammary glands. The nearly septuagenarian vicar appears to have had gynecomastia, as it is a common condition in elderly men, and is sometimes associated with obesity. Gynecomastia is the most likely explanation for these findings. Clin. Anat. 31:641–644, 2018. © 2018 Wiley Periodicals, Inc.     

Results of metal-on-metal hip resurfacing in patients 40 years old and younger

The prevalence of total hip arthroplasty in young patients is small but increasing. We analyzed the results of metal-on-metal hip resurfacing (MMHR) in patients aged 40 years or less. In total 74 operations were performed on 64 patients. Mean age at operation was 33.2 years. HHS averaged 92.3 points at latest follow-up, mean UCLA activity was 8.2. Patients with comorbidity evinced lower scores in HHS, in UCLA activity and in quality of life than patients without comorbidities. Eight revisions (10.8 %) were performed, of which seven due to adverse reaction to metal debris. Seven-year survival was 90.5 %. The functional outcome of hip resurfacing in this cohort was excellent, but overall survival was unsatisfactory. Further analysis is required to verify the role of hip resurfacing among young and active patients.     

Challenges in investigation of diabetes-related aviation fatalities—an analysis of 1491 subsequent aviation fatalities in USA during 2011–2016

Diabetes mellitus (DM) could cause pilot incapacitation and result in aviation fatalities. The mechanisms could be directly as a consequence of acute hypoglycemia/subacute diabetic ketoacidosis (DKA) or indirectly as an acute cardiovascular event by contributing to the development of atherosclerosis in coronary or carotid and cerebral arteries. In this study, DM-related fatal flight accidents in the US National Transport Bureau’s database between years 2011–2016 were analyzed with special emphasis on postmortem (PM) glucose levels and correlation of toxicological reports with anamnestic information on DM. Additionally, autopsy results on coronary arteries were reviewed. In 43 out of 1491 (~ 3%) fatal accidents pilots had DM. Postmortem glucose or glycated hemoglobin percentage (Hb1Ac) was measured in 12 of the 43 cases; while antidiabetic medication was found in 14 of the cases (only two of the cases had both glucose measurements and medication). With the increasing prevalence of DM, a possibility of pilot incapacitation due to DM or complications of DM should be actively studied, even if no anamnestic information of DM was available. While PM hypoglycemia is difficult to assess, we propose a systematic investigation based on measurement of glucose, Hb1Ac%, and ketone bodies, and documentation of atherosclerotic lesions in major arteries to identify or rule out DM as a cause of pilot incapacitation.
