Recently, the cognitive abilities of patients with amyotrophic lateral sclerosis (ALS) have been found to be impaired along with the neurodegeneration of motor neurons. Electroencephalography (EEG) of end-stage ALS patients has reportedly shown specific features based on neuronal network modulations, differing from EEG of other patients with cognitive failure and dementia. However, EEG of end-stage ALS patients during anaesthesia has not yet been reported. A 64-year-old male ALS patient with locked-in state (LIS), supported by tracheostomy positive-pressure ventilation (TPPV) and enteral nourishment for 9years, underwent scheduled general anaesthesia for repair of a fractured mandible...

REVIEW
Bryan K Ward, John P Carey, Lloyd B Minor
Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal...

PURPOSE: 14-3-3 zeta protein plays a potential protective role in neurodegenerative disease. Given that glaucoma and neurodegenerative diseases share a similar pathogenesis, it is possible that 14-3-3 zeta may have a similar protective effect in the glaucomatous process. In the present study, we measured the expression of 14-3-3 zeta in vivo (mouse eyes) and in vitro in a transformed human trabecular meshwork (HTM) cell line, TM-1, and assessed the possible roles of this protein in dexamethasone (DEX)-treated eyes and HTM cells...

Glaucoma is a complex neurodegenerative disease characterized by progressive visual dysfunction leading to vision loss. Retinal ganglion cells are the primary affected neuronal population, with a critical insult damaging their axons in the optic nerve head. This insult is typically secondary to harmfully high levels of intraocular pressure (IOP). We have previously determined that early mitochondrial abnormalities within retinal ganglion cells lead to neuronal dysfunction, with age-related declines in NAD (NAD(+) and NADH) rendering retinal ganglion cell mitochondria vulnerable to IOP-dependent stresses...

Central Sleep Apnea (CSA) is characterized by intermittent apneas and hypopneas during sleep that result from absent central respiratory drive. CSA occurs almost exclusively during non-rapid-eye-movement (NREM) sleep due to enhanced neuronal ventilatory drive during REM sleep that makes central apneas highly unlikely to form. A 45-year-old obese African American female presented with co-existing Obstructive Sleep Apnea (OSA) and CSA, not in the form of mixed or complex sleep apnea. Peculiarly, her CSA occurred only during rapid-eye-movement (REM) sleep, which is exceedingly rare...

High Alt Med Biol 00:000-000, 2017.-High-altitude retinal hemorrhages (HARHs) are seen at altitudes more than 3000 m, are usually multiple, flame shaped, and adjacent to blood vessels. Development near the macula causes blurring of vision, otherwise, they are symptomless and self-limiting. They often develop during the first few days after ascent to high altitude and subjects often suffer from acute mountain sickness (AMS) or high-altitude cerebral edema (HACE)...

Automated calf feeding systems are becoming more common on US dairy farms. The objective of this study was to evaluate calf health in these systems and to identify risk factors associated with adverse health outcomes on farms in the upper Midwest United States. Over an 18-mo period on bimonthly farm visits to 38 farms, calves (n = 10,179) were scored for attitude, ear, eye, and nasal health, as well as evidence of diarrhea (hide dirtiness score of perianal region, underside of the tail, and tailhead). For all health score categories, a score of 0 represented an apparently healthy animal...

Various immune response pathways are altered during early, predegenerative stages of glaucoma; however, whether the early immune responses occur secondarily to or independently of neuronal dysfunction is unclear. To investigate this relationship, we used the Wld(s) allele, which protects from axon dysfunction. We demonstrate that DBA/2J.Wld(s) mice develop high intraocular pressure (IOP) but are protected from retinal ganglion cell (RGC) dysfunction and neuroglial changes that otherwise occur early in DBA/2J glaucoma...
