Personal activity trackers are an inexpensive and easy way for people to record their physical activity and simple biometric data. As these devices have increased in availability and sophistication, their use in daily life and in medicine has grown. This column will briefly explore what these devices are, what types of data they can track, and how that data can be used. It will also discuss potential problems with trackers and how librarians can help patients and physicians manage and protect activity data. A brief list of currently available activity trackers is also included. © 2016, Published with license by Taylor & Francis.

PURPOSE: To present and discuss a case representing both a new sign and symptom of prostaglandin-associated periorbitopathy. CASE REPORT: An 83-year-old female patient presented for a 6-month glaucoma follow-up in July 2013 with no specific visual or comfort complaints. The patient had a 14-year history of bilateral primary open angle glaucoma and a 13-year history of once daily bimatoprost use in both eyes. Evaluation at previous examinations revealed long eyelashes, tight eyelids, small palpebral fissures, and deepening of the upper eyelid sulcus. During slit-lamp examination of the anterior segment, it was noted that the patient’s eyelids clicked intermittently when she blinked. The patient had not previously noticed the clicking and it was determined to be present in each eye individually. The eyelid clicking has been noted to be present in every follow-up examination since it was discovered in July 2013. CONCLUSIONS: Prostaglandin-associated periorbitopathy and the resulting cosmetic effects noticed visually by patients are well documented. Our case represents a new audible sign and symptom that may be found with prostaglandin-associated periorbitopathy but has not to our knowledge been reported in the literature. © 2016 American Academy of Optometry

PURPOSE OF REVIEW: Myopia is progressing at faster than predicted rates for reasons that are still unknown. The public health consequences worldwide, are also becoming a burden on healthcare costs. There have been numerous studies published attempting to determine the cause of myopia progression and methods of prevention. RECENT FINDINGS: The review examines recent articles that have tried to explain myopia progression and the increase in prevalence across the globe. Additionally, this review provides up-to-date research on current treatment options and their efficacy. SUMMARY: Although this topic has been an increased area of study recently, even more studies are needed to find a definitive treatment for the prevention of myopia.

Advances in building technologies are combining energy efficiency, networked sensors, and data recording in exciting ways. Modern facilities can adjust lighting, heating, and cooling outputs to maximize efficiency, provide better physical security, improve wayfinding for occupants, and provide detailed reports of building use. This column will briefly explore the idea of “smart buildings,” describe some of the technologies that are being developed for these buildings, and explore their implications for libraries. A brief listing of selected smart building technologies is also provided. © 2016, Published with license by Taylor & Francis.

Histoplasma urine antigen (UAg) detection is an important biomarker for histoplasmosis. The clinical significance of low-positive (<0.6 ng/ml) UAg results was evaluated in 25 patients without evidence of prior Histoplasma infection. UAg results from 12/25 (48%) patients were considered falsely positive, suggesting that low-positive UAg values should be interpreted cautiously. Copyright © 2014, American Society for Microbiology.

Tenotomy and debridement of diseased tendon can resolve symptoms due to chronic degenerative tendinopathic lesions (i.e. tennis elbow). Recent improvements in musculoskeletal ultrasound imaging and the development of a minimally invasive ultrasound-guided ultrasonic energy debridement tool, the TX1 (Tenex Health, Inc., Lake Forrest, CA), have created a viable less invasive alternative to open tenotomy and debridement procedures. The rationale behind this novel and minimally invasive procedure is to ultrasonographically visualize the diseased portion of the tendon and guide a small ultrasonic-energy debridement tool under dynamic sonographic imaging into the tendinopathic region to complete a percutaneous tenotomy and debridement procedure. The TX1-debridement tool is safe and has demonstrated similar or better outcomes to open tenotomy and debridement procedures. © 2013 Elsevier Inc.

Background: Elbow tendinopathy is the most common cause of elbow pain affecting active populations. Surgical excision is reserved for patients with refractory symptoms. Percutaneous ultrasonic tenotomy performed under local anesthesia also removes degenerated tissue and therefore provides an alternative treatment option to surgical excision. This investigation prospectively documented the safety and 1-year efficacy of ultrasonic percutaneous tenotomy performed by a single operator. Methods: Nineteen patients, aged 38 to 67years, in whom >6months of conservative management for medial (7) or lateral (12) elbow tendinopathy had failed were prospectively studied. All patients were treated with percutaneous ultrasonic tenotomy of the elbow by a single operator. Visual analog scale (VAS) for pain, the 11-item version of the Disabilities of the Arm, Shoulder, and Hand (Quick DASH) index, and the Mayo Elbow Performance Score (MEPS) were assessed by an independent observer before treatment and at 6weeks, 3months, 6months, and 12months after treatment. Results: No procedural complications occurred. Total treatment time was <15minutes, and ultrasonic energy time averaged 38.6 ± 8.8seconds per procedure. Average VAS scores were significantly improved from 6.4 to 2.6 at 6 weeks and were 0.7 at 12 months (. P<.0001). Similar improvement occurred with the Quick DASH (pretreatment, 44.1; 12 months, 8.6, P<.0001) and MEPS (pretreatment, 59.1; 12 months, 83.4; P<.0001). Conclusion: Percutaneous ultrasonic tenotomy performed under local anesthesia appears to be a safe and effective treatment option for chronic, refractory lateral or medial elbow tendinopathy up to 1 year after the procedure. © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

Objective: To assess whether high school football played between 1946 and 1956, when headgear was less protective than today, was associated with development of neurodegenerative diseases later in life. Methods: All male students who played football from 1946 to 1956 in the high schools of Rochester, Minnesota, plus a non-football-playing referent group of male students in the band, glee club, or choir were identified. Using the records-linkage system of the Rochester Epidemiology Project, we reviewed (from October 31, 2010, to March 30, 2011) all available medical records to assess later development of dementia, Parkinson disease (PD), or amyotrophic lateral sclerosis (ALS). We also compared the frequency of dementia, PD, or ALS with incidence data from the general population of Olmsted County, Minnesota. Results: We found no increased risk of dementia, PD, or ALS among the 438 football players compared with the 140 non-football-playing male classmates. Parkinson disease and ALS were slightly less frequent in the football group, whereas dementia was slightly more frequent, but not significantly so. When we compared these results with the expected incidence rates in the general population, only PD was significantly increased; however, this was true for both groups, with a larger risk ratio in the non-football group. Conclusion: Our findings suggest that high school students who played American football from 1946 to 1956 did not have an increased risk of later developing dementia, PD, or ALS compared with non-football-playing high school males, despite poorer equipment and less regard for concussions compared with today and no rules prohibiting head-first tackling (spearing). © 2012 Mayo Foundation for Medical Education and Research.

Near field communication is a method for sending and receiving small amounts of data across very short distances wirelessly. This technology is already available in a number of mobile devices and has many possible uses, including electronic payment, access control, and information exchange. This article will explain the basic principles of near field communication, discuss some of the ways it can be used in libraries, and explore some possible concerns with the technology. A list of resources for additional information is also included. © 2013 Copyright Matthew B. Hoy.
