“…The VP, which refers to the presence of gas in the IVD, is a relatively common radiological finding in humans and dogs, especially from CT, with an incidence of 6% in canine vertebral CT scans (14, 16, 22, 30, 31). Although an intervertebral VP can indicate vertebral disc degeneration and herniation, it should not be considered a unique identifier for spinal compression.…”

Three dogs were presented with lumbosacral hyperesthesia. Computerized tomography scans were performed in all the cases, and magnetic resonance imaging was also performed in cases 1 and 3. There was intervertebral disc (IVD) protrusion causing nerve root compression and epidural gas accumulation in all the three cases. The gas-filled cystic structures in cases 1 and 3 were within the spinal canal; in case 2, the gas was within the disc protrusion. The IVD vacuum phenomenon is relatively common in dogs, but the formation of an epidural gas accumulation in cases of a lumbar disc protrusion is rare. The clinical significance of these epidural gas accumulations is unknown. Two of the dogs were treated surgically, improved after surgery, and showed no signs of pain in the follow-up examinations.

“…19/20 studies clearly reported age, breed, and sex, of the participants. Weight (28)(29)(30)(31) and level of activity (4, 32) were additionally reported in some studies. 13/20 included studies did not clearly report duration and presence of clinical signs among the participants.…”

Objective: To critically appraise the literature exploring the surgical treatment of degenerative lumbosacral stenosis in dogs. Background: Several surgical procedures to treat degenerative lumbosacral stenosis (DLSS) in the dog have been reported, however, definitive criteria for surgical technique preference are currently lacking (1). Evidentiary value and methods: A critical appraisal tool that examined the conduct and reporting of studies on the results of surgical treatment of DLSS was designed and, after a systematic search and screening of the literature, a critical appraisal was performed in 20 papers. Results: Results showed that 18/20 studies included did not clearly report inclusion and exclusion criteria and in 14/20 it was unclear whether consecutive inclusion of participants was applied. 19/20 studies reported age, breed, and sex of the participants, and 13/20 did not report duration and prevalence of clinical signs. In 13/20 studies, it was considered that the condition was not measured in a standard and reliable way. Objective outcome measures were used in 7/20 studies. Conclusion and application: The results demonstrate that there is room for improvement in the conduct and reporting quality of case series so that rigorous data can be generated and analysed, to inform research design, guide clinical practice, and improve veterinary healthcare delivery.

“…In applications where high electric or magnetic fields are required, optical fiber based headphones and microphones are very useful. These applications include team communication among medics working on a patient in an MRI (Magnetic resonance imaging) system during surgeries that are MRI-guided [ 72 ]. In oil industries, optical fibers are used to measure temperature and pressure in oil wells [ 73 , 74 ].…”

Light has found applications in data transmission, such as optical fibers and waveguides and in optoelectronics. It consists of a series of electromagnetic waves, with particle behavior. Photonics involves the proper use of light as a tool for the benefit of humans. It is derived from the root word “photon”, which connotes the tiniest entity of light analogous to an electron in electricity. Photonics have a broad range of scientific and technological applications that are practically limitless and include medical diagnostics, organic synthesis, communications, as well as fusion energy. This will enhance the quality of life in many areas such as communications and information technology, advanced manufacturing, defense, health, medicine, and energy. The signal transmission methods used in wireless photonic systems are digital baseband and RoF (Radio-over-Fiber) optical communication. Microwave photonics is considered to be one of the emerging research fields. The mid infrared (mid-IR) spectroscopy offers a principal means for biological structure analysis as well as nonintrusive measurements. There is a lower loss in the propagations involving waveguides. Waveguides have simple structures and are cost-efficient in comparison with optical fibers. These are important components due to their compactness, low profile, and many advantages over conventional metallic waveguides. Among the waveguides, optofluidic waveguides have been found to provide a very powerful foundation for building optofluidic sensors. These can be used to fabricate the biosensors based on fluorescence. In an optical fiber, the evanescent field excitation is employed to sense the environmental refractive index changes. Optical fibers as waveguides can be used as sensors to measure strain, temperature, pressure, displacements, vibrations, and other quantities by modifying a fiber. For some application areas, however, fiber-optic sensors are increasingly recognized as a technology with very interesting possibilities. In this review, we present the most common and recent applications of the optical fiber-based sensors. These kinds of sensors can be fabricated by a modification of the waveguide structures to enhance the evanescent field; therefore, direct interactions of the measurand with electromagnetic waves can be performed. In this research, the most recent applications of photonics components are studied and discussed.
