PURPOSE: Whereas acute complications following elective hand surgery have been assumed to be rare, the incidence of 30-day unplanned reoperation and/or admission for the most common elective procedures has not been well described. Our goal was to calculate the incidence and identify the risk factors associated with these complications in a busy academic practice. METHODS: Our institution's quality assurance database was examined retrospectively for unplanned reoperations and/or admissions within 30 days in adults undergoing elective procedures with 2 senior attending surgeons from February 2006 to January 2016...

Switchable materials, due to their potential applications in the fields of sensors, photonic devices, digital processing, etc., have been developed drastically. However, they still face great challenges in effectively inducing multiple molecular switching. Herein organic-inorganic hybrid compounds, an emerging class of hydrosoluble optoelectronic-active materials, welcome a new member with smart unique optical/electrical (fluorescence/dielectric) dual switches (switching ON/OFF), that is, [C5H13NBr][Cd3Br7] (1) in the form of both a bulk crystal and an ultraflexible monodirectional thin film, which simultaneously exhibits fast dielectric/fluorescent dual switching triggered by an optical/thermal/electric signal with a high signal-to-noise ratio of 35 (the highest one in the known optical/dielectric dual molecular switches)...

Continuous brain imaging techniques can be beneficial for the monitoring of neurological pathologies (such as epilepsy or stroke) and neuroimaging protocols involving movement. Among existing ones, functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG) have the advantage of being noninvasive, nonobstructive, inexpensive, yield portable solutions, and offer complementary monitoring of electrical and local hemodynamic activities. This article presents a novel system with 128 fNIRS channels and 32 EEG channels with the potential to cover a larger fraction of the adult superficial cortex than earlier works, is integrated with 32 EEG channels, is light and battery-powered to improve portability, and can transmit data wirelessly to an interface for real-time display of electrical and hemodynamic activities...

BACKGROUND Although percutaneous trigger digit release is common, controversy exists regarding its safety. The purpose of this study was to evaluate the feasibility and safety of the neurovascular displacement by local hydraulic dilatation (LHD) during percutaneous trigger digit release. MATERIAL AND METHODS Ten cadaver hands with 50 digits were dissected in this anatomical study. The distance between bilateral neurovascular bundles in each digit was measured before LHD and after LHD. The difference between the measured data before LHD and those after LHD in the same digit was compared to assess the feasibility of the neurovascular displacement by LHD...

Complex vector light fields, classically entangled in polarization and phase, have become ubiquitous in a wide variety of research fields. This has triggered the demonstration of a wide variety of generation techniques. Of particular relevance are those based on computer-controlled devices due to their great flexibility. In particular, spatial light modulators have demonstrated their high capabilities to generate any vector beam, with various spatial profiles and polarization distributions. Here, we put forward a novel technique that exploits the superposition principle in optics to enable the simultaneous generation of many vector beams using a single digital hologram...

PURPOSE: Mucopolysaccharidoses (MPS) are a group of rare lysosomal storage disorders associated with involvement of multiple organs along with a generalised skeletal dysplasia. Both haematopoetic stem cell transplant and enzyme replacement therapy have improved the outlook for patients while surgery remains high-risk and there is little information on clinical or functional outcome to justify many of the surgical procedures performed. This paper aims to summarise the orthopaedic surgical procedures in MPS patients for which quality of life (QoL) and functional data are available and to describe additional QoL and functional measurement tools of relevance to the assessment of orthopaedic outcomes in MPS...

Stenosing flexor tenosynovitis, or trigger finger, has been treated with open, endoscopic, and percutaneous tendon sheath incisions. A comparison of techniques highlights increased cost, procedure time, and postoperative recovery associated with open surgical treatment. We conducted a study of the efficacy of percutaneous tendon sheath incision as a treatment for trigger digit. Using percutaneous tendon sheath incisions, a single surgeon treated 596 trigger digits (429 patients) over a 10-year period. Successful release was defined as symptom relief on follow-up, or patient request for no further treatment...

"Stringhalt" is a horse condition that causes one or both hind legs to spasm when walking, trotting or backing. The condition is thought to be related to a neurological cause from either plant toxicity or peripheral nerve injury. The prognosis is poor and the horse's performance and quality of life can be affected. Treatment has included surgically cutting the digital extensors with varied results. The objective of the study is to utilize soft tissue release via acupressure, trigger point and myofascial release to decrease symptoms of stringhalt...
