Impact on the reduction of CO2 emissions due to the use of telemedicine.

Digital health can reduce CO emissions thanks to telemedicine and access to digital test results and medical reports. However, the environmental impact of digital health activity is not well known. Here, we show that telemedicine reduces CO emissions.

Gold Coast diagnostic criteria: Implications for ALS diagnosis and clinical trial enrollment.

Diagnostic criteria for amyotrophic lateral sclerosis (ALS) are complex, incorporating multiple levels of certainty from possible through to definite, and are thereby prone to error. Specifically, interrater variability was previously established to be poor, thereby limiting utility as diagnostic enrollment criteria for clinical trials. In addition, the different levels of diagnostic certainty do not necessarily reflect disease progression, adding confusion to the diagnostic algorithm.

Ultrasound assessment of optic disc edema in patients with headache.

Point-of-care ocular ultrasonography is emerging as a powerful tool to evaluate emergency department (ED) patients at risk for ophthalmologic and intracranial pathology.We present cases of 3 patients in whom optic disc swelling was identified using ocular ultrasound. Causes for optic disc swelling in our patients included idiopathic intracranial hypertension, secondary syphilis, and malignant hypertension with associated hypertensive retinopathy.
