Blood pressure reactivity at onset of mental stress determines sympathetic vascular response in young adults.

Physiol Rep 2018 Dec;6(24):e13944

School of Medicine, Western Sydney University, Sydney, New South Wales, Australia.

We have previously shown in young males that the rate of rise in blood pressure (BP) at the onset of mental stress determines whether or not muscle sympathetic nerve activity (MSNA) has a role in driving the pressor response. The aim of this study was to investigate these interactions in young females. BP and MSNA were recorded continuously in 19 females and 21 males during 2-min mental stressors (mental arithmetic and Stroop test). Read More

Authors:

Development 2018 Dec 14;145(24). Epub 2018 Dec 14.

In contrast to nerves in the central nervous system, peripheral nerves are highly regenerative following injury. Regeneration is critically dependent on Schwann cells, the main glial cell type of the peripheral nervous system, but whether an additional stem cell or progenitor population also contributes has been a matter of contention. A paper in this issue of Development now addresses this issue with a characterisation of Schwann cell behaviour in the homeostatic and regenerating mouse peripheral nerve. Read More

Extended Duration of Hyperglycemia Result in Human-Like Corneal Nerve Lesions in Mice With Alloxan- and Streptozotocin-Induced Type 1 Diabetes.

Invest Ophthalmol Vis Sci 2018 Dec;59(15):5868-5875

Laboratory of Pathology, Faculty of Pharmaceutical Science, Setsunan University, Osaka, Japan.

Purpose: Previous experimental studies assessing corneal nerves as a measure of the severity of diabetic peripheral neuropathy have yielded discordant results; this may have been due to the effect of the short duration of the induced diabetes. We investigated whether increases in the duration of hyperglycemia result in the development of corneal lesions in a mouse model of alloxan (AL)- or streptozotocin (STZ)-induced type 1 diabetes. We further determined whether corneal nerve fiber density, intraepidermal nerve fiber density (IENFD), and sural nerve morphology can be used as morphologic markers of diabetic peripheral neuropathy in rodent models.

Department of Clinical Epidemiology and Biostatistics, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

Purpose: To investigate whether the relationship between circumpapillary vascular density (cpVD) and visual field (VF) mean sensitivity (MS) differs between primary open-angle (POAG) and angle-closure glaucoma (PACG).

Methods: The cpVD and retinal nerve fiber layer thickness (RNFLT) were obtained using optical coherence tomography angiography (OCTA, AngioVue/RTVue-XR) in 146 eyes from 146 subjects (age- and VF mean deviation-matched 86 POAG and 60 PACG). Global and regional relationships (superotemporal [ST], superonasal [SN], nasoupper [NU], nasolower [NL], inferonasal [IN], inferotemoporal [IT], temporolower [TL], and temporoupper [TU] sectors) were estimated between cpVD and VF MS using multiple linear regression models controlling for the confounding variables in two disease categories.

Am J Med Genet A 2018 Dec 14. Epub 2018 Dec 14.

Virginia Tech Carilion Research Institute, Roanoke, Virginia.

Heterozygous loss-of-function mutations in the X-linked gene CASK are associated with mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH) and ophthalmological disorders including optic nerve atrophy (ONA) and optic nerve hypoplasia (ONH). Recently, we have demonstrated that CASK mice display ONH with 100% penetrance but exhibit no change in retinal lamination or structure. It is not clear if CASK loss-of-function predominantly affects retinal ganglion cells, or if other retinal cells like photoreceptors are also involved. Read More

All sensory stimuli produce transient excitability changes in various central nervous system circuits. One example is prepulse inhibition (PPI), which is the inhibition generated by a preceding weak stimulus (prepulse) over the reflex response to a subsequent suprathreshold stimulus. The PPI is a ubiquitous phenomenon, common to many different sensory modalities. Read More

Optic Disc Coloboma in children - prevalence, clinical characteristics and associated morbidity.

Acta Ophthalmol 2018 Dec 13. Epub 2018 Dec 13.

Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden.

Purpose: The aim of the study was to report prevalence, ocular outcome, neurological characteristics, cognitive and behavioural problems in children with optic disc coloboma (ODC).

Methods: This was a population-based, cross-sectional study of 31 children between 2 and 18 years of age diagnosed with ODC. The children were part of a larger cohort of 184 children with congenital optic disc malformations. Read More

Fruitful first experience with an 8K ultra-high-definition endoscope for laparoscopic colorectal surgery.

Asian J Endosc Surg 2018 Dec 13. Epub 2018 Dec 13.

Department of Gastrointestinal Surgery, St. Luke's International Hospital, Tokyo, Japan.

We performed laparoscopic surgery for three cases of colorectal cancer using an 8K ultra-high-definition endoscopic system, which offers 16-fold higher resolution than the current 2K high-definition endoscope. The weight of the camera has been successfully reduced to 370 g. To maximize the advantages of the 8K ultra-high-definition endoscope, surgery was performed by darkening the room and placing a large 85-in. Read More

Review of rodent hypertensive glaucoma models.

Acta Ophthalmol 2018 Dec 13. Epub 2018 Dec 13.

Department of Ophthalmology & Visual Sciences, Chinese University of Hong Kong, Hong Kong, Hong Kong.

Glaucoma is a neurodegenerative disease characterized by the progressive loss of retinal ganglion cells (RGCs). Elevated intraocular pressure (IOP) is a primary risk factor for the development and progression of glaucoma. Rodent models of glaucoma have greatly improved our understanding of the pathophysiology of glaucoma and served as a useful tool to investigate neuroprotective agents. Read More

Patient Reported Symptom-Mapping in Carpal Tunnel Syndrome.

Muscle Nerve 2018 Dec 14. Epub 2018 Dec 14.

Clinical Professor of Orthopaedic Surgery, Wayne State University School of Medicine, 25700 Southwood Dr., Southfield, MI, USA, 48075, 2487526328.

Introduction: To date, no method has been described or utilized to study the distribution of symptoms in carpal tunnel syndrome. We describe a technique of symptom-mapping that yields a population-based "anatomic profile" of carpal tunnel syndrome.

Methods: Symptoms were mapped on visual questionnaires depicting the volar hand, wrist and forearm. Read More

Validation of diagnostic methods for traumatic sensory neuropathy and neuropathic pain.

Muscle Nerve 2018 Dec 14. Epub 2018 Dec 14.

Departments of Clinical Neurophysiology, University of Turku and Turku University Hospital, Postal Box 52, 20521, Turku, Finland.

Introduction: We evaluated diagnostic value of sensory tests during recovery from iatrogenic sensory neuropathy using intraoperatively verified nerve injury with subjective symptoms as gold standard.

Methods: Inferior alveolar nerves were monitored neurophysiologically throughout mandibular osteotomy in 19 patients. Sensory disturbance was registered and sensation tested using clinical and quantitative sensory (QST) and neurophysiologic tests postoperatively at 1, 3, 6, 12 months. Read More
